1Deferoxamine promotes recovery of traumatic spinal cord injury by inhibiting ferroptosis显示文摘Ferroptosis is an iron-dependent novel cell death pathway. Deferoxamine, a ferroptosis inhibitor, has been reported to promote spinal cord injury repair. It has yet to be clarified whether ferroptosis inhibition represents the mechanism of action of Deferoxamine on spinal cord injury recovery. A rat model of Deferoxamine at thoracic 10 segment was established using a modified Allen's method. Ninety 8-week-old female Wistar rats were used. Rats in the Deferoxamine group were intraperitoneally injected with 100 mg/kg Deferoxamine 30 minutes before injury. Simultaneously, the Sham and Deferoxamine groups served as controls. Drug administration was conducted for 7 consecutive days. The results were as follows:(1) Electron microscopy revealed shrunken mitochondria in the spinal cord injury group.(2) The Basso, Beattie and Bresnahan locomotor rating score showed that recovery of the hindlimb was remarkably better in the Deferoxamine group than in the spinal cord injury group.(3) The iron concentration was lower in the Deferoxamine group than in the spinal cord injury group after injury.(4) Western blot assay revealed that, compared with the spinal cord injury group, GPX4, xCT, and glutathione expression was markedly increased in the Deferoxamine group.(5) Real-time polymerase chain reaction revealed that, compared with the Deferoxamine group, mRNA levels of ferroptosis-related genes Acyl-CoA synthetase family member 2(ACSF2) and iron-responsive element-binding protein 2(IREB2) were up-regulated in the Deferoxamine group.(6) Deferoxamine increased survival of neurons and inhibited gliosis. These findings confirm that Deferoxamine can repair spinal cord injury by inhibiting ferroptosis. Targeting ferroptosis is therefore a promising therapeutic approach for spinal cord injury.Xue Yao Yan Zhang Jian Hao Hui-Quan Duan Chen-Xi Zhao Chao Sun Bo Li Bao-You Fan Xu Wang Wen-Xiang Li Xuan-Hao Fu Yong Hu Chang Liu Xiao-Hong Kong Shi-Qing Feng 2019Neural Regeneration Research2019,14,3:35
2The Association of Maternal Body Composition and Dietary Intake with the Risk of Gestational Diabetes Mellitus during the Second Trimester in a Cohort of Chinese Pregnant Women显示文摘Objective To investigate the association of maternal body composition and dietary intake with the risk of gestational diabetes mellitus(GDM). Methods A total 154 GDM subjects and 981 controls were enrolled in a prospective cohort study in 11 hospitals from May 20, 2012 to December 31, 2013. Bioelectrical impedance analysis and dietary surveys were used to determine body composition and to evaluate the intake of nutrients in subjects at 21-24 weeks' gestation(WG). Logistic regression analysis was applied to explore the relationships of maternal body composition and dietary intake with the risk of GDM morbidity. Results Age, pre-pregnant body weight(BW), and body mass index(BMI) were associated with increased risk of GDM. Fat mass(FM), fat mass percentage(FMP), extracellular water(ECW), BMI, BW, energy, protein, fat, and carbohydrates at 21-24 WG were associated with an increased risk of GDM. In contrast, fat free mass(FFM), muscular mass(MM), and intracellular water(ICW) were associated with a decreased risk of GDM. Conclusion Maternal body composition and dietary intake during the second trimester of pregnancy were associated with the risk of GDM morbidity.Xu Qing Gao Zhi Ying Li Li Ming Wang Lu Zhang Qian Teng Yue Zhao Xia Ge Sheng Jing Hong Jiang Yang Yong Tao Liu Xiao Jun Lyu Chun Jian Mao Lun Yu Xiao Ming Liu Ying Hua Kong Ai Jing Yang Xue Yan Liu Zhao Zhang Yong Wang Jin Zhang Xin Sheng Xue Chang Yong Lu Yan Ping 2016Biomedical and Environmental Sciences2016,29,1:29
3Serum pepsinogen Ⅱ is a better diagnostic marker in gastric cancer显示文摘AIM:To investigate screening makers for gastric cancer,we assessed the association between gastric cancer and serum pepsinogens(PGs).METHODS:The subjects comprised 450 patients with gastric cancer,111 individuals with gastric atrophy,and 961 healthy controls.Serum anti-Helicobacter pylori(H.pylori) immunoglobulin G(IgG),PGⅠand PG Ⅱ were detected by enzyme-linked immunosorbent assay.Gastric atrophy and gastric cancer were diagnosed by endoscopy and histopathological examinations.Odds ratios and 95%CIs were calculated using multivariate logistic regression.RESULTS:Rates of H.pylori infection remained high in Northeastern China.Rates of H.pylori IgG positivity were greater in the gastric cancer and gastric atrophy groups compared to the control group(69.1% and 75.7% vs 49.7%,P < 0.001).Higher levels of PG Ⅱ(15.9 μg/L and 13.9 μg/L vs 11.5 μg/L,P < 0.001) and lower PGⅠ/PG Ⅱ ratio(5.4 and 4.6 vs 8.4,P < 0.001) were found in patients with gastric cancer or gastric atrophy compared to healthy controls,whereas no correlation was found between the plasma PGⅠconcentration and risk of gastric cancer(P = 0.537).In addition,multivariate logistic analysis indicated that H.pylori infection and atrophic gastritis were independent risk factors for gastric cancer.Lower plasma PGⅠ/PG Ⅱ ratio was associated with higher risks of atrophy and gastric cancer.Furthermore,plasma PG Ⅱ?level?significantly?correlated?with?H.pyloriinfected gastric cancer.CONCLUSION:Serum PG Ⅱ concentration and PG Ⅰ/PG Ⅱ ratio are potential biomarkers for H.pyloriinfected gastric disease.PG Ⅱ is independently associated with risk of gastric cancer.Xue-Yuan Cao Zhi-Fang Jia Mei-Shan Jin Dong-Hui Cao Fei Kong Jian Suo Jing Jiang 2012World Journal of Gastroenterology2012,18,48:27
4Differentiation of isolated human umbilical cord mesenchymal stem cells into neural stem cells显示文摘AIM:To investigate whether umbilical cord human mesenchymal stem cell(UC-MSC)was able to differentiate into neural stem cell and neuron in vitro.·METHODS:The umbilical cords were obtained from pregnant women with their written consent and the approval of the Clinic Ethnics Committee.UC-MSC were isolated by adherent culture in the medium contains 20%fetal bovine serum(FBS),then they were maintained in the medium contain 10%FBS and induced to neural cells in neural differentiation medium.We investigated whether UC-MSC was able to differentiate into neural stem cell and neuron in vitro by using flow cytometry,reverse transcriptase-polymerase chain reaction(RT-PCR)and immunofluorescence(IF)analyzes.·RESULTS:A substantial number of UC-MSC was harvested using the tissue explants adherent method at about 2wk.Flow cytometric study revealed that these cells expressed common markers of MSCs,such as CD105(SH2),CD73(SH3)and CD90.After induction of differentiation of neural stem cells,the cells began to form clusters;RT-PCR and IF showed that the neuron specific enolase(NSE)and neurogenic differentiation 1-positive cells reached 87.3%±14.7%and 72.6%±11.8%,respectively.Cells showed neuronal cell differentiation after induced,including neuron-like protrusions,plump cell body,obviously and stronger refraction.RT-PCR and IF analysis showed that microtubule-associated protein 2(MAP2)and nuclear factor-M-positive cells reached 43.1%±10.3%and 69.4%±19.5%,respectively.·CONCLUSION:Human umbilical cord derived MSCscan be cultured and proliferated in vitro and differentiate into neural stem cells,which may be a valuable source for cell therapy of neurodegenerative eye diseases.Song Chen Wei Zhang Ji-Ming Wang Hong-Tao Duan Jia-Hui Kong Yue-Xin Wang Meng Dong Xue Bi Jian Song 2016International Journal of Ophthalmology(English edition)2016,9,1:22

6Whole-genome sequencing of 508 patients identifies key molecular features associated with poor prognosis in esophageal squamous cell carcinoma显示文摘Esophageal squamous cell carcinoma(ESCC)is a poor-prognosis cancer type with limited understanding of its molecular etiology.Using 508 ESCC genomes,we identified five novel significantly mutated genes and uncovered mutational signature clusters associated with metastasis and patients’outcomes.Several functional assays implicated that NFE2L2 may act as a tumor suppressor in ESCC and that mutations in NFE2L2 probably impaired its tumor-suppressive function,or even conferred oncogenic activities.Additionally,we found that the NFE2L2 mutations were significantly associated with worse prognosis of ESCC.We also identified potential noncoding driver mutations including hotspot mutations in the promoter region of SLC35E2 that were correlated with worse survival.Approximately 5.9%and 15.2%of patients had high tumor mutation burden or actionable mutations,respectively,and may benefit from immunotherapy or targeted therapies.We found clinically relevant coding and noncoding genomic alterations and revealed three major subtypes that robustly predicted patients’outcomes.Collectively,we report the largest dataset of genomic profiling of ESCC useful for developing ESCC-specific biomarkers for diagnosis and treatment.Yongping Cui Hongyan Chen Ruibin Xi Heyang Cui Yahui Zhao Enwei Xu Ting Yan Xiaomei Lu Furong Huang Pengzhou Kong Yang Li Xiaolin Zhu Jiawei Wang Wenjie Zhu Jie Wang Yanchun Ma Yong Zhou Shiping Guo Ling Zhang Yiqian Liu Bin Wang Yanfeng Xi Ruifang Sun Xiao Yu Yuanfang Zhai Fang Wang Jian Yang Bin Yang Caixia Cheng Jing Liu Bin Song Hongyi Li Yi Wang Yingchun Zhang Xiaolong Cheng Qimin Zhan Yanhong Li Zhihua Liu-Show 2020Cell Research2020,30,10:19

8Sedimentary Evolution of the Holocene Subaqueous Clinoform off the Southern Shandong Peninsula in the Western South Yellow Sea显示文摘Based on the stratigraphic sequence formed since the last glaciation and revealed by 3000 km long high-resolution shallow seismic profiles and the core QDZ03 acquired recently off the southern Shandong Peninsula, we addressed the sedimentary characteristics of a Holocene subaqueous clinoform in this paper. Integrated analyses were made on the core QDZ03, including sedimentary facies, sediment grain sizes, clay minerals, geochemistry, micro paleontology, and AMS 14 C dating. The result indicates that there exists a Holocene subaqueous clinoform, whose bottom boundary generally lies at 15–40 m below the present sea level with its depth contours roughly parallel to the coast and getting deeper seawards. The maximum thickness of the clinoform is up to 22.5 m on the coast side, and the thickness contours generally spread in a banded way along the coastline and becomes thinner towards the sea. At the mouths of some bays along the coast, the clinoform stretches in the shape of a fan and its thickness is evidently larger than that of the surrounding sediments. This clinoform came into being in the early Holocene(about 11.2 cal kyr BP) and can be divided into the lower and upper depositional units(DU 2 and DU 1, respectively). The unit DU 2, being usually less than 3 m in thickness and formed under a low sedimentation rate, is located between the bottom boundary and the Holocene maximum flooding surface(MFS), and represents the sediment of a post-glacial transgressive systems tract; whereas the unit DU 1, the main body of the clinoform, sits on the MFS, belonging to the sediment of a highstand systems tract from middle Holocene(about 7–6 cal kyr BP) to the present. The provenance of the clinoform differs from that of the typical sediments of the Yellow River and can be considered as the results of the joint contribution from both the Yellow River and the proximal coastal sediments of the Shandong Peninsula, as evidenced by the sediment geochemistry of the core. As is controlled mainly by coactions of multiple factors such as the Holocene sea-level changes, sediment supplies and coastal dynamic conditions, the development of the clinoform is genetically related with the synchronous clinoform or subaqueous deltas around the northeastern Shandong Peninsula and in the northern South Yellow Sea in the spatial distribution and sediment provenance, as previously reported, with all of them being formed from the initial stage of the Holocene up to the present.QIU Jiandong LIU Jian SAITO Yoshiki YANG Zigeng YUE Baojing WANG Hong KONG Xianghuai 2014Journal of Ocean University of China2014,13,5:17
9Altitudinal changes of surface pollen and vegetation on the north slope of the Middle Tianshan Mountains,China显示文摘To provide information on vegetation patterns and altitudinal distributions of pollen assemblage in surface soil layers,their complicated relationships in a dryland mountain-basin system in northwestern China and a realistic basis for paleovegetational reconstruction,we investigated 86 vegetation quadrats and analyzed 80 soil samples from the surface soil layers along an altitudinal transect on the north slope of the Middle Tianshan Mountains from alpine cushion vegetation at 3,510 m near glacier to desert vegetation at 460 m in the Gurbantunggut Desert.According to surface pollen assemblages and the results of the detrended correspondence analysis,the transect can be divided into six major altitudinal pollen zones as alpine cushion vegetation,alpine and subalpine meadows,montane Picea forest,forest-steppe ecotone,Artemisia desert and typical desert,which basically reflect the characteristics of the mountainous vegetation patterns on the north slope of the Middle Tianshan Mountains.However,Picea pollen also exists outside the spruce forest,Chenopodiaceae and Artemisia pollen appeared above the elevation of 1,300 m,indicating that most of them might be introduced from lower elevations by upslope winds.Airborne pollen researches from three regions at different elevations further suggest that a high-frequency northwest anabatic wind has a remarkable influence on the transportation and dispersion of surface pollen in the area.YANG Zhenjing ZHANG Yun REN Haibao YAN Shun KONG Zhaochen MA Keping NI Jian 2016Journal of Arid Land2016,8,5:17
10Laparoscopic vs computerized tomography-guided radiofrequency ablation for large hepatic hemangiomas abutting the diaphragm显示文摘AIM: To compare safety and therapeutic efficacy of laparoscopic radiofrequency(RF) ablation vs computed tomography(CT)-guided RF ablation for large hepatic hemangiomas abutting the diaphragm.METHODS: We retrospectively reviewed our sequential experience of treating 51 large hepatic hemangiomas abutting the diaphragm in 51 patients by CT-guided or laparoscopic RF ablation due to either the presence of symptoms and/or the enlargement of hemangioma.Altogether, 24 hemangiomas were ablated via a CTguided percutaneous approach(CT-guided ablation group), and 27 hemangiomas were treated via a laparoscopic approach(laparoscopic ablation group).RESULTS: The mean diameter of the 51 hemangiomas was 9.6 ± 1.8 cm(range, 6.0-12.0 cm). There was nodifference in the diameter of hemangiomas between the two groups(P > 0.05). RF ablation was performed successfully in all patients. There was no difference in ablation times between groups(P > 0.05). There were 23 thoracic complications in 17 patients: 15(62.5%, 15/24) in the CT-guided ablation group and2(7.4%, 2/27) in the laparoscopic ablation group(P< 0.05). According to the Dindo-Clavien classification,two complications(pleural effusion and diaphragmatic rupture grade Ⅲ) were major in two patients. All others were minor(grade Ⅰ). Both major complications occurred in the CT-guided ablation group. The minor complications were treated successfully with conservative measures, and the two major complications underwent treatment by chest tube drainage and thoracoscopic surgery, respectively. Complete ablation was achieved in 91.7%(22/24) and 96.3%(26/27) in the CT-guided and the laparoscopic ablation groups,respectively(P > 0.05).CONCLUSION: Laparoscopic RF ablation therapy should be used as the first-line treatment option for large hepatic hemangiomas abutting the diaphragm.It avoids thermal injury to the diaphragm and reduces thoracic complications.Jun Gao Jian Kong Xue-Mei Ding Shan Ke Hai-Gang Niu Zong-Hai Xin Chun-Min Ning Shi-Gang Guo Xiao-Long Li Long Zhang Yong-Hong Dong Wen-Bing Sun 2015World Journal of Gastroenterology2015,21,19:16

12A Prospective Randomized Multicenter Controlled Trial on Salvianolate for Treatment of Unstable Angina Pectoris in A Chinese Elderly Population显示文摘Objective: To evaluate the efficacy and safety of salvianolate in elderly patients with unstable angina pectoris(UAP). Methods: A prospective double-blind randomized placebo-controlled multicenter trial in elderly patients with UAP from 13 third-grade class-A hospitals in China was performed. A total of 318 patients were randomly allocated in a 1:1 ratio to an experimental group(160 patients) and a control group(158 patients). The experimental group was treated with salvianolate for 14 days on the basis of conventional medicine, and the control group was given a placebo for 14 days with the same criteria. Follow-up was lasted 28 days in both groups. The primary endpoint was biweekly frequency of angina pectoris attacks. The secondary endpoints included biweekly dosage of nitroglycerin, the Seattle Angina Questionnaire, angina pectoris severity and duration, myocardial injury markers, high-sensitivity C-reactive protein(hs-CRP) and N-terminal pro-B-type natriuretic peptide(NT-proBNP), as well as major adverse cardiovascular events(MACEs). Safety was assessed according to adverse events and serious adverse events. Results: Baseline characteristics were similar between treatment groups. Compared with those in the control group, the frequency of biweekly angi na attacks(2.92 vs. 4.08, P =0.025), th e biweekly dosage of nitroglycerin, as well as the severity and duration of angina attacks(P <0.01) were reduced by salvianolate. The Seattle Angina Questionnaire score was also significantly improved in the experimental group than in the control group(P <0.05). No significant differences were observed between the two groups with respect to the incidence of MACEs. Salvianolate was well tolerated. Conclusions: Salvianolate appear to have efficacy and well tolerated for elderly patients with UAP.CUI Hua LI Xiao-ying GAO Xue-wen LU Xiang WU Xiu-ping WANG Xiao-fei ZHENG Xiang-qing HUANG Kui LIU Feng LUO Zhi YUAN Hui-shu SUN Gang KONG Jian DU Xiao-hong ZHENG Jin LIU Hong-ying ZHANG Wen-ju 2019Chinese Journal of Integrative Medicine2019,25,10:13
13Prostate cancer in Asia:A collaborative report显示文摘The incidence of prostate cancer(PCa)within Asian population used to be much lower than in the Western population;however,in recent years the incidence and mortality rate of PCa in some Asian countries have grown rapidly.This collaborative report summarized the latest epidemiology information,risk factors,and racial differences in PCa diagnosis,current status and new trends in surgery management and novel agents for castration-resistant prostate cancer.We believe such information would be helpful in clinical decision making for urologists and oncologists,health-care ministries and medical researchers.Rui Chen Shancheng Ren Ming Kwong Yiu Ng Chi Fai Wai Sam Cheng Lap Hong Ian Seiji Naito Tadashi Matsuda Elijah Kehinde Ali Kural Jason Yichun Chiu Rainy Umbas Qiang Wei Xiaolei Shi Liqun Zhou Jian Huang Yiran Huang Liping Xie Lulin Ma Changjun Yin Danfeng Xu Kexin Xu Zhangqun Ye Chunxiao Liu Dingwei Ye Xin Gao Qiang Fu Jianquan Hou Jianlin Yuan Dalin He Tiejun Pan Qiang Ding Fengshuo Jin Benkang Shi Gongxian Wang Xiuheng Liu Dongwen Wang Zhoujun Shen Xiangbo Kong Wanhai Xu Yaoliang Deng Haibo Xia Alexa NCohen Xu Gao Chuanliang Xu Yinghao Sun 2014Asian Journal of Urology2014,1,1:13
14Shenfu injection attenuates lipopolysaccharide-induced myocardial inflammation and apoptosis in rats显示文摘Shenfu injection(SFI), a Chinese medicinal product, shows potent efficacy in treating sepsis. The aim of the present study was to clarify the protective effects of SFI against lipopolysaccharide(LPS)-induced myocardial inflammation and apoptosis.Experiments were carried out in Sprague-Dawley(SD) rats treated with LPS or LPS + SFI, and in H9 C2 cardiomyocytes. The sepsisassociated myocardial inflammation and apoptosis was induced by the intraperitoneal injection of LPS(20 mg·kg–1). SFI attenuated the increased expression of tumor necrosis factor(TNF)-α and interleukin(IL)-1β induced by LPS both in serum and heart. In LPS group,cell viability was reduced, and reversed after SFI administration. LPS treatment increased the expression levels of cleaved-caspase 3 and Bax, and those of Bcl2 and Bcl2/Bax. These two trends were reversed by SFI administration. The expression levels of phosphorylated mitogen-activated protein kinase kinase(p-MEK) and phosphorylated extracellular regulated protein kinases(p-ERK) were increased by LPS, and reversed by SFI. MEK inhibitor U0126 attenuated the apoptosis induced by LPS. These results indicate that SFI could treat LPS-induced cardiac dysfunction. In conclusion, SFI attenuates the inflammation and apoptosis induced by LPS via downregulating the MEK and ERK signaling pathways.CHEN Rui-Juan RUI Qing-Lin WANG Qiong TIAN Fang WU Jian KONG Xiang-Qing 2020Chinese Journal of Natural Medicines2020,18,3:12
15Pollen record and environmental evolution of Caotanhu wetland in Xinjiang since 4550 cal. a BP显示文摘This paper presents a multi-proxy reconstruction of the climate change in Caotanhu wetland using pollen, phytolith and charcoal records, and the data of loss of ignition (LOI), grain size analysis, and susceptibility. Results reveal that between 4550 and 2500 cal. a BP, a dry climatic condition was not favorable for the accumulation of peat. Since 2500 cal. a BP, the climate became humid and the wetland developed with abundant freshwater aquatic plants, which contributed to peat accumulation. Never-theless, alternate periods of rain and dry climate occurred during that period. Between 2500 and 1810 cal. a BP (550 BC―140 AD), the climate was more humid than at present. A lot of emerged plants, such as Phragmites, Typha and Sparganium, and freshwater green algae grew in the wetland which was sur-rounded by desert-steppe vegetation composed mainly of Chenopodiaceae, Artemisia, Compositae and Thalictrum. However, from 1810 to 1160 cal. a BP (140―790 AD), the water level started to decrease and hydrophyte species reduced greatly, but some Phragmites still grew in the wetland and around it was desert vegetation with high proportion of Chenopodiaceae and Artemisia. Then from 1160 to 650 a BP (790―1300 AD), it entered a period of desert-steppe with abundant mesic and xerophytic plants. And a lot of aquatic plants prevailed in the wetland. Here, what is noticeable is that percentages of arboreal pollen, consisting mainly of Betula and Picea, increased greatly and reached a maximal value of 27.2%, in which, Betula percentages rose to 23.2%. Hence, it is reasonable to conclude that Betula grew in the highland of the wetland, or Picea timberline shifted downward resulting in the increase of percentages of Betula and Picea pollen, which were transported into the wetland by flood or wind. But since 650 cal. a BP, desert vegetation prevailed around the wetland again with dominant Chenopodiaceae and Ar-temisia, and the climate was similar to modern one.

17Anti-proliferation effects of Twist gene silencing in gastric cancer SGC7901 cells显示文摘AIM:To study the role of Twist gene in gastric cancer by gene silencing,including the potential of induction of apoptosis,cell cycle arrest,and proliferation inhibition in human malignant gastric SGC7901 cells.METHODS:The expression level of Twist in gastric cancer samples was measured by immunohistochemistry.The effects of Twist gene silencing were detected at both m RNA and protein levels by RT-PCR and Western blot.We also evaluated the cell proliferation and apoptosis by CCK-8 assay and flow cytometry.We determined the activity of caspase-3 and caspase-9 with a caspase activity assay kit.Cell cycle distribution was analyzed by flow cytometry.Cell migration and invasion ability was evaluated by wound scratch assay and Boyden chamber assay.RESULTS:Twist protein was highly expressed in gastric cancer samples.Twist gene silencing significantly induced apoptosis,cell cycle arrest at G0/G1 phase,proliferation inhibition,and reduced the ability of migration and invasion in human gastric cancer SGC7901 cells.Meanwhile,both caspase-3 and caspase-9 were activated.CONCLUSION:The Twist gene could serve as a potential molecular target for gene therapy of gastric cancer with targeted small interfering RNA.Hui Zhang Jian Gong Di Kong Hong-Yi Liu 2015World Journal of Gastroenterology2015,21,10:11
18Fluctuation of Picea timberline and paleoenvironment onthe northern slope of Tian-shan Mountains during the late Holocene显示文摘As a good indicator of Holocene climate, the fluctuation of alpine timberline is a synthetical result of impacts of many environmental factors dur-ing geological and historical periods and modern times. As the dominant tree species of mountainous conifer forests on the northern slope of Tianshan Mountains in Xinjiang, the distribution of Picea schrenkiana and its population size are sensitive to climatic change. The typical natural profile of Huashuwozi and the nearby Xiaoxigou archaeologi-cal profile, located in Quanzijie Township, Jimusaer County in Xinjiang, were chosen to analyze and compare the relative high-resolution pollen records, and to measure 14C dating and SEM (scanning elec-tron microscope) microstructure for charcoal frag-ments contained in Xiaoxigou profile’s cultural layers. The results show that in these two profiles, the high percentages of Picea (more than 20% and 35%, re-spectively) appeared in the stratum of the same pe-riod (2000-1300 a BP), which corresponds to the charcoal fragment’s age of Picea schrenkiana con-tained in Xiaoxigou cultural layers. These results convincingly revealed that during the period of 2000-1300 a BP, the timberline for Picea schrenkiana on the northern slope of Tianshan Mountains in Xinjiang declined by about 330m compared with the present.ZHANG Yun KONG Zhaochen YAN Shun YANG Zhenjing NI Jian 2006Chinese Science Bulletin2006,51,14:9

20White Matter Abnormalities in Major Depression Biotypes Identified by Diffusion Tensor Imaging显示文摘Identifying data-driven biotypes of major depressive disorder(MDD) has promise for the clarification of diagnostic heterogeneity. However, few studies have focused on white-matter abnormalities for MDD subtyping. This study included 116 patients with MDD and118 demographically-matched healthy controls assessed by diffusion tensor imaging and neurocognitive evaluation.Hierarchical clustering was applied to the major fiber tracts, in conjunction with tract-based spatial statistics, to reveal white-matter alterations associated with MDD.Clinical and neurocognitive differences were compared between identified subgroups and healthy controls. With fractional anisotropy extracted from 20 fiber tracts, cluster analysis revealed 3 subgroups based on the patterns of abnormalities. Patients in each subgroup versus healthy controls showed a stepwise pattern of white-matter alterations as follows: subgroup 1(25.9% of patient sample),widespread white-matter disruption;subgroup 2(43.1% of patient sample), intermediate and more localized abnormalities in aspects of the corpus callosum and left cingulate;and subgroup 3(31.0% of patient sample),possible mild alterations, but no statistically significant tract disruption after controlling for family-wise error. The neurocognitive impairment in each subgroup accompanied the white-matter alterations: subgroup 1, deficits in sustained attention and delayed memory;subgroup 2, dysfunction in delayed memory;and subgroup 3, no significant deficits. Three subtypes of white-matter abnormality exist in individuals with major depression, those having widespread abnormalities suffering more neurocognitive impairments, which may provide evidence for parsing the heterogeneity of the disorder and help optimize typespecific treatment approaches.Sugai Liang Qiang Wang Xiangzhen Kong Wei Deng Xiao Yang Xiaojing Li Zhong Zhang Jian Zhang Chengcheng Zhang Xin-min Li Xiaohong Ma Junming Shao Andrew J.
