| 1 | Huangqi Guizhi Wuwu Decoction for treating diabetic peripheral neuropathy:a meta-analysis of 16 randomized controlled trials显示文摘OBJECTIVE:This meta-analysis was performed to systematically assess the efficacy and safety of the Chinese herbal medicine Huangqi Guizhi Wuwu Decoction(HGWWD) for treating diabetic peripheral neuropathy.DATA SOURCES:Six electronic databases,including the Cochrane Library,MEDLINE database,Chinese Biomedical Database,Chinese National Knowledge Infrastructure Database,Chinese Science and Technique Journals Database,and the Wanfang Database,were search ed on the internet for randomized controlled trials published up until 1 December 2015.The search terms included 'Chinese herbal medicine','diabetic peripheral neuropathy' and 'randomized controlled trials' in Chinese and in English.DATA SELECTION:We included randomized controlled trials using HGWWD/modified HGWWD for the treatment group,without restriction for the control group.We assessed literature quality in accordance with the Cochrane Review Handbook.A random or a fixed effects model was used to analyze outcomes using Rev Man 5.2 software.OUTCOME MEASURES:The primary outcomes were changes in symptoms and nerve conduction velocities.The secondary outcomeswere fasting blood glucose and hemorheological indexes.RESULTS:Sixteen randomized controlled trials,with a total of 1,173 patients,were included.Meta-analysis revealed that the efficacy of HGWWD for diabetic peripheral neuropathy was significantly superior compared with the control treatment(i.e.,control group)(risk ratio = 0.36,95% confidence interval(CI):0.29–0.46,Z =8.33,P < 0.00001) Compared with the control group,there was an increase in median motor nerve conduction velocity(mean difference(MD) = 3.46,95%CI:1.88–5.04,Z = 4.30,P < 0.01) and median sensory nerve conduction velocity(MD = 3.30,95%CI:2.04–4.56,Z = 5.14,P < 0.01).There was also an increase in peroneal motor nerve conduction velocity(MD = 3.22,95%CI:2.45–3.98,Z = 8.21,P < 0.01) and peroneal sensory nerve conduction velocity(MD = 3.05,95%CI:2.01–4.09,Z = 5.75,P < 0.01) in the treatment groups.No significant difference in fasting blood glucose was found between the treatment groups and the control groups(MD =-0.12,95%CI:-0.42–0.19,Z = 0.76,P = 0.45).Plasma viscosity was significantly decreased after treatment(MD =-0.11,95%CI:-0.21 to-0.02,Z = 2.30,P = 0.02).No significant difference in fibrinogen was detectable(MD =-0.53,95%CI:-1.28–0.22,Z = 1.38,P = 0.17).Four trials reported that treatment groups experienced no adverse reactions.Adverse events were not mentioned in the other 12 trials.No trial reported the incidence of complications,quality of life outcomes,or health economics.CONCLUSION:HGWWD treatment improves diabetic neurologic symptoms and ameliorates nerve conduction velocities.Our study suggests that HGWWD may have significant therapeutic efficacy for the treatment of diabetic peripheral neuropathy.However,the methodological quality of the randomized controlled trials was generally low.Larger and better-designed randomized controlled trials are required to more reliably assess the clinical effectiveness of HGWWD. | Bing Pang Tian-yu Zhao Lin-hua Zhao Fang Wan Ru Ye Qiang Zhou Feng Tian Xiao-lin Tong | 2016 | Neural Regeneration Research2016，11，8： | 32 |
| 2 | Cystatin C is a biomarker for predicting acute kidney injury in patients with acute-on-chronic liver failure显示文摘AIM:To investigate serum cystatin C level as an early biomarker for predicting acute kidney injury(AKI)in patients with acute-on-chronic liver failure(ACLF).METHODS:Fifty-six consecutive patients with hepatitis B virus-related ACLF who had normal serum creatinine(Cr)level(<1.2 mg/dL in men,or<1.1 mg/dL in women)were enrolled in the Liver Failure Treatment and Research Center of Beijing 302 Hospital between August 2011 and October 2012.Thirty patients with chronic hepatitis B(CHB)and 30 healthy controls in the same study period were also included.Measurement of serum cystatin C(CysC)was performed by a particle-enhanced immunonephelometry assay using the BN Prospec nephelometer system.The ACLF patients were followed during their hospitalization period.RESULTS:In the ACLF group,serum level of CysC was 1.1±0.4 mg/L,which was significantly higher(P<0.01)than those in the healthy controls(0.6±0.3mg/L)and CHB patients(0.7±0.2 mg/L).During the hospitalization period,eight ACLF patients developed AKI.Logistic regression analysis indicated that CysC level was an independent risk factor for AKI development(odds ratio=1.8;95%CI:1.4-2.3,P=0.021).The cutoff value of serum CysC for prediction of AKI in ACLF patients was 1.21 mg/L.The baseline CysC-based estimated glomerular filtration rate(eGFR CysC)was significantly lower than the creatinine-based eGFR(eGFR CG and eGFR MDRD)in ACLF patients with AKI,suggesting that baseline eGFR CysC represented early renal function in ACLF patients while the Cr levels were still within the normal ranges.CONCLUSION:Serum CysC provides early prediction of renal dysfunction in ACLF patients with a normal serum Cr level. | Zhi-Hong Wan Jian-Jun Wang Shao-Li You Hong-Ling Liu Bing Zhu Hong Zang Chen Li Jing Chen Shao-Jie Xin | 2013 | World Journal of Gastroenterology2013，19，48： | 20 |

| 4 | Using Fuzzy Theory and Variable Weights for Water Quality Evaluation in Poyang Lake, China显示文摘Achieving water purity in Poyang Lake has become a major concern in recent years, thus appropriate evaluation of spatial and temporal water quality variations has become essential. Variations in 11 water quality parameters from 15 sampling sites in Poyang Lake were investigated from 2009 to 2012. An integrative fuzzy variable evaluation(IFVE) model based on fuzzy theory and variable weights was developed to measure variations in water quality. Results showed that: 1) only chlorophyll-a concentration and Secchi depth differed significantly among the 15 sampling sites(P < 0.01), whereas the 11 water quality parameters under investigation differed significantly throughout the seasons(P < 0.01). The annual variations of all water quality variables except for temperature, electrical conductivity, suspended solids and total phosphorus were considerable(P < 0.05). 2) The IFVE model was reasonable and flexible in evaluating water quality status and any possible ′bucket effect′. The model fully considered the influences of extremely poor indices on overall water quality. 3) A spatial analysis indicated that anthropogenic activities(particularly industrial sewage and dredging) and lake bed topography might directly affect water quality in Poyang Lake. Meanwhile, hydrological status and sewage discharged into the lake might be responsible for seasonal water quality variations. | LI Bing YANG Guishan WAN Rongrong ZHANG Lu ZHANG Yanhui DAI Xue | 2017 | Chinese Geographical Science2017，27，1： | 15 |
| 5 | Understanding hydraulic fracture propagation behavior in tight sandstone–coal interbedded formations: an experimentalinvestigation显示文摘Whether hydraulic fractures could connect multiple gas zones in the vertical plane is the key to fracturing treatment to jointly exploit coalbed methane and tight sandstone gas through integrative hydraulic fracturing in tight sandstone–coal interbedded formations. Laboratory true triaxial hydraulic fracturing experiments were conducted on layered specimens with di erent combination types of natural sandstone and coal to simulate the propagation behavior of hydraulic fractures. The effects of the fracture initiation position, fracturing fluid viscosity and injection rate were discussed. The results showed that di erent fracture morphologies could be found. When initiating from coal seams, three patterns of fracture initiation and propagation were obtained:(1) The main hydraulic fracture initiated and propagated along the natural fractures and then diverged due to the effects of in situ stress and formed secondary fractures.(2) The hydraulic fracture initiated and propagated in the direction of the maximum horizontal stress.(3) Multiple fractures initiated and propagated at the same time. With the same fracturing fluid viscosity and injection rate, the hydraulic fractures initiating in sandstones had greater chances than those in coal seams to penetrate interfaces and enter neighboring layers. Excessively small or large fracturing fluid viscosity and injection rate would do harm to the vertical extension height of the induced fracture and improvement of the stimulated reservoir volume. Compared with operation parameters(fracturing fluid viscosity and injection rate), the natural weak planes in coals were considered to be the key factor that a ected the fracture propagation path. The experimental results would make some contributions to the development of tight sandstone–coal interbedded reservoirs. | Peng Tan Yan Jin Liang Yuan Zhen-Yu Xiong Bing Hou Mian Chen Li-Ming Wan | 2019 | Petroleum Science2019，16，1： | 14 |

| 8 | Identification and Typing of Respiratory Adenoviruses in Guangzhou, Southern China Using a Rapid and Simple Method显示文摘Human adenoviruses (HAdVs), especially HAdV-B3, -E4 and -B7, are associated with Acute Respiratory Disease in Chinese children, and occasionally in adults. In order to establish and document the profiles of the respiratory adenovirus pathogen among children in Guangzhou, Southern China, a rapid, simple and practical method for identification and typing of respiratory adenoviruses was developed and evaluated. One pair of universal PCR primers was designed according to the conserved region of the hexon gene, which can detect not only HAdV-B3, -E4 and -B7, but also HAdV-B14, -F40 and -F41, with a specific 300bp PCR product. Three pairs of type-specific PCR primers were also designed according to the hypervariable regions of the hexon gene to type HAdV-B3, -E4 and -B7 by three independent PCR reactions, making it easy to optimize the PCR conditions. By using this method, one hundred throat swab specimens collected during Oct 2010 to Dec 2011 and suspected of being positive for adenoviral infection were identified and typed for adenoviruses. Of these samples, fifty-five were adenovirus-positive. The most common HAdV type was HAdV-B3, identified in 92.7% of samples, which is not only consistent with the data reported in 2004-2006, but also consistent with the recent report in Hangzhou, eastern China, indicating that HAdV-B3 has been circulating in Guangzhou, and maybe in eastern China, for many years. The method for the respiratory adenovirus identification and typing we developed is rapid, simple and practical, which has a potential in the real-time surveillance of circulating adenovirus strains and also to provide etiological evidence for the adenovirus-relative disease control and prevention in China. | Guiyuan Han Hongling Niu Suhui Zhao Bing Zhu Changbing Wang Yungang Liu Mingjie Zhang Shu Yang Feitong Liu Chengsong Wan Qiwei Zhang | 2013 | Virologica Sinica2013，28，2： | 10 |
| 9 | Alginate oligosaccharide-induced intestinal morphology, barrier function and epithelium apoptosis modifications have beneficial effects on the growth performance of weaned pigs显示文摘Background: Alginate oligosaccharide(AOS), produced from alginate by alginate lyase-mediated depolymerisation, is a potential substitute for antibiotics and possesses growth-enhancing effects. Nevertheless, the mechanisms by which AOS regulates porcine growth remain to be elucidated. Therefore, we investigated the AOS-mediated changes in the growth performance of weaned pigs by determining the intestinal morphology, barrier function,as well as epithelium apoptosis.Methods: Twenty-four weaned pigs were distributed into two groups(n = 12) and received either a basal diet(control group) or the same diet supplemented with 100 mg/kg AOS. On d 15, D-xylose(0.1 g/kg body weight)was orally administrated to eight randomly selected pigs per treatment, and their serum and intestinal mucosa samples were collected 1 h later.Results: Our results showed that inclusion of AOS in the diet for 2 wk increased(P < 0.05) the average daily body weight gain in weaned pigs. Notably, AOS supplementation ameliorated the intestinal morphology and barrier function, as suggested by the enhanced(P < 0.05) intestinal villus height, secretory immunoglobulin A content and goblet cell counts. Compared to the control group, AOS ingestion both decreased(P < 0.05) the total apoptotic percentage and increased(P < 0.05) the proportion of S phase in the intestinal epithelial cells. Furthermore, AOS not only up-regulated(P < 0.05) the B-cell lymphoma-2(BCL2) transcriptional level but also down-regulated(P < 0.05) the B-cell lymphoma-2-associated X protein(BAX), cysteinyl aspartate-specific proteinase-3(caspase-3) and caspase-9 transcriptional levels in the small intestine.Conclusions: In summary, this study provides evidence that supplemental AOS beneficially affects the growth performance of weaned pigs, which may result from the improved intestinal morphology and barrier function,as well as the inhibited enterocyte death, through reducing apoptosis via mitochondria-dependent apoptosis. | Jin Wan Jiao Zhang Daiwen Chen Bing Yu Xiangbing Mao Ping Zheng Jie Yu Junqiu Luo Jun He | 2018 | Journal of Animal Science and Biotechnology2018，9，4： | 10 |
| 10 | Recent advances on phylogenomics of gymnosperms and a new classification显示文摘Living gymnosperms comprise four major groups:cycads,Ginkgo,conifers,and gnetophytes.Relationships among/within these lineages have not been fully resolved.Next generation sequencing has made available a large number of sequences,including both plastomes and single-copy nuclear genes,for reconstruction of solid phylogenetic trees.Recent advances in gymnosperm phylogenomic studies have updated our knowledge of gymnosperm systematics.Here,we review major advances of gymnosperm phylogeny over the past 10 years and propose an updated classification of extant gymnosperms.This new classification includes three classes(Cycadopsida,Ginkgoopsida,and Pinopsida),five subclasses(Cycadidae,Ginkgoidae,Cupressidae,Pinidae,and Gnetidae),eight orders(Cycadales,Ginkgoales,Araucariales,Cupressales,Pinales,Ephedrales,Gnetales,and Welwitschiales),13 families,and 86 genera.We also described six new tribes including Acmopyleae Y.Yang,Austrocedreae Y.Yang,Chamaecyparideae Y.Yang,Microcachrydeae Y.Yang,Papuacedreae Y.Yang,and Prumnopityeae Y.Yang,and made 27 new combinations in the genus Sabina. | Yong Yang David Kay Ferguson Bing Liu Kang-Shan Mao Lian-Ming Gao Shou-Zhou Zhang Tao Wan Keith Rushforth Zhi-Xiang Zhang | 2022 | Plant Diversity2022，44，4： | 10 |

| 14 | Construction and selection of the natural immune Fab antibody phage display library from patients with colorectal cancer显示文摘AIM: To construct the natural immune Fab antibody phage display libraries of colorectal cancer and to select antibodies related with colorectal cancer.METHODS: Extract total RNA from tissue of local cancer metastasis lymph nodes of patients with colorectal cancer.RT-PCR was used to amplify the heavy chain Fd and light chain к and the amplification products were inserted successively into the vector pComb3 to construct the human libraries of Fab antibodies. They were then panned by phage display technology. By means of Dot immunoblotting and ELISA, the libraries were identified and the Fab phage antibodies binding with antigens of colorectal cancer were selected.RESULTS: The amplified fragments of Fd and к gained by RT-PCR were about 650bp. Fd and к PCR products were subsequently inserted into the vector pComb3, resulting in a recombination rate of 40% and the volume of Fab phage display library reached 1.48 x 106. The libraries were enriched about 120-fold by 3 cycles of adsorption-elution- multiplication (panning). Dot immunoblotting showed Fab expressions on the phage libraries and ELISA showed 5clones of Fab phage antibodies which had binding activities with antigens of colorectal cancer.CONCLUSION: The natural immune Fab antibody phage display libraries of colorectal cancer were constructed. They could be used to select the relative antibodies of colorectal cancer. | Bao-Ping Wu~1 Bing Xiao~1 Tian-Mo Wan~1 Ya-Li Zhang~1 Zhen-Shu Zhang~1 Dian-Yuan Zhou~1 Zhuo-Sheng Lai~1 Chun-Fang Gao~2 1 Institute for Digestive Diseases,Nanfang Hospital,Guangzhou 510515,Guangdong Province,China2 Surgical Department of Colon and Rectum,150 Central Hospital,Luoyang 471031,Henan Province,China | 2001 | World Journal of Gastroenterology2001，7，6： | 9 |
| 15 | Precipitation regulates plant gas exchange and its long-term response to climate change in a temperate grassland显示文摘Aims Climate change largely impacts ecosystem carbon and water cycles by changing plant gas exchange,which may further cause positive or negative feedback to global climate change.However,long-term global change manipulative experiments are seldom conducted to reveal plant ecophysiological responses to climatic warming and altered precipitation regimes.Methods An 8-year field experiment with both warming and increased precipitation was conducted in a temperate grassland in northern China.We measured leaf gas exchange rates(including plant photosynthesis,transpiration and instantaneous water use efficiency[WUE])of two dominant plant species(Stipa sareptana var.krylovii and Agropyron cristatum)from 2005 to 2012(except 2006 and 2010)and those of other six species from 2011 to 2012.Important Findings Increased precipitation significantly stimulated plant photosynthetic rates(A)by 29.5%and 19.9%and transpiration rates(E)by 42.2%and 51.2%for both dominant species S.sareptana var.krylovii and A.cristatum,respectively,across the 8 years.Similarly,A and E of the six plant functional types were all stimulated by increased precipitation in 2011 and 2012.As the balance of A and E,the instantaneous WUEs of different plant species had species-specific responses to increased precipitation.In contrast,neither warming nor its interaction with increased precipitation significantly affected plant leaf gas exchange rates.Furthermore,A and E of the two dominant species and their response magnitudes to water treatments positively correlated with rainfall amount in July across years.We did not find any significant difference between the short-term versus long-term responses of plant photosynthesis,suggesting the flexibility of leaf gas exchange under climate change.The results suggest that changing precipitation rather than global warming plays a prominent role in determining production of this grassland in the context of climate change. | Bing Song Shuli Niu Shiqiang Wan | 2016 | Journal of Plant Ecology2016，9，5： | 8 |
| 16 | Relationships among hamstring muscle optimal length and hamstring flexibility and strength显示文摘Background:Hamstring muscle strain injury(hamstring injury) due to excessive muscle strain is one of the most common injuries in sports.The relationships among hamstring muscle optimal lengths and hamstring flexibility and strength were unknown,which limited our understanding of risk factors for hamstring injury.This study was aimed at examining the relationships among hamstring muscle optimal length and flexibility and strength.Methods:Hamstring flexibility and isokinetic strength data and three-dimensional kinematic data for hamstring isokinetic tests were collected for11 male and 10 female recreational athletes.The maximal hamstring muscle forces,optimal lengths,and muscle lengths in standing were determined for each participant.Results:Hamstring muscle optimal lengths were significantly correlated to hamstring flexibility score and gender,but not to hamstring strength.The greater the flexibility score,the longer the hamstring muscle optimal length.With the same flexibility score,females tend to have shorter hamstring optimal muscle lengths compared to males.Hamstring flexibility score and hamstring strength were not correlated.Hamstring muscle optimal lengths were longer than but not significantly correlated to corresponding hamstring muscle lengths in standing.Conclusion:Hamstring flexibility may affect hamstring muscle maximum strain in movements.With similar hamstring flexibility,hamstring muscle maximal strain in a given movement may be different between genders.Hamstring muscle lengths in standing should not be used as an approximation of their optimal lengths in calculation of hamstring muscle strain in musculoskeletal system modeling. | Xianglin Wan Feng Qu William E.Garrett Hui Liu Bing Yu | 2017 | Journal of Sport and Health Science2017，6，3： | 6 |
| 17 | Effects of flexibility and strength training on peak hamstring musculotendinous strains during sprinting显示文摘Background:Hamstring injury is one of the most common injuries in sports involving sprinting.Hamstring flexibility and strength are often considered to be modifiable risk factors in hamstring injury.Understanding the effects of hamstring flexibility or strength training on the biomechanics of the hamstring muscles during sprinting could assist in improving prevention strategies and rehabilitation related to these injuries.The purpose of this study was to determine the effects of altering hamstring flexibility or strength on peak hamstring musculotendinous strain during sprinting.Methods:A total of 20 male college students(aged 18-24 years)participated and were randomly assigned to either a flexibility intervention group or a strength intervention group.Each participant executed exercise training 3 times a week for 8 weeks.Flexibility,sprinting,and isokinetic strength testing were performed before and after the 2 interventions.Paired t tests were performed to determine hamstring flexibility or strength intervention effects on optimal hamstring musculotendinous lengths and peak hamstring musculotendinous strains during sprinting.Results:Participants in the flexibility intervention group significantly increased the optimal musculotendinous lengths of the semimembranosus and biceps long head(p<0.026)and decreased peak musculotendinous strains in all 3 bi-articulate hamstring muscles(p<0.004).Participants in the strength-intervention group significantly increased the optimal musculotendinous lengths of all 3 hamstring muscles(p<0.041)and significantly decreased their peak musculotendinous strain during sprinting(p<0.017).Conclusion:Increasing hamstring flexibility or strength through exercise training may assist in reducing the risk of hamstring injury during sprinting for recreational male athletes. | Xianglin Wan Shangxiao Li Thomas M.Best Hui Liu Hanjun Li Bing Yu | 2021 | Journal of Sport and Health Science2021，10，2： | 6 |
| 18 | Perivenous application of fibrin glue prevents the early injury of jugular vein graft to arterial circulation in rabbits显示文摘Background Placement of an external support has been reported to prevent intimal hyperplasia of vein grafts. However, it is limited by potential complications. In the present study, we investigated the effect of fibrin glue on preventing vein graft failure as perivenous application. Methods Twenty-four rabbits were divided into non-supported group (n=12) and fibrin glue group (n=12). All animals underwent unilateral jugular vein into common carotid artery interposition grafting and then fibrin glue was applied as perivenous support. Samples of tissues were harvested after 4 weeks. Results The vein grafts with fibrin glue demonstrated a statistically significant decrease in proliferating cell nuclear antigen in the medial/intimal region [13.38% (11.26%-15.11%)] compared with non-supported vein grafts [31.22% (27.15%-35.98%)] (P<0.001). Light microscopy showed remarkable attenuation of endothelial cell loss and numerous microvessels in neoadventitia in the fibrin glue group compared with the non-supported group. The smooth muscle cells migrated into adventitia significantly in fibrin glue group, whereas the smooth muscle cells migrated into intima in non-supported group.

| 19 | Cylindrical vector beam fiber laser with a symmetric two-mode fiber coupler显示文摘We demonstrate a passively mode-locked all-fiber laser generating cylindrical vector beams(CVBs)only using a symmetric two-mode fiber optical coupler(TMF-OC)for both high-order mode excitation and splitting.Theoretical analyses show that for a symmetric TMF-OC with appropriate taper diameter,the second-order mode can be excited and coupled into output tap with high purity due to the effective index difference of different modes.Based on the fabricated TMF-OC,the passively mode-locked fiber laser delivers pulsed CVBs at a center wavelength of 1564.4 nm with 3 d B linewidth of 11.2 nm,pulse duration of 2.552 ps,and repetition rate of3.96 MHz.The purity of both radially and azimuthally polarized beams is estimated to be over 91%.Due to simple fabrication method of the TMF-OC and high purity of the generated CVBs,this mode-locked CVB fiber laser with all-fiber configuration has potential applications in optical trapping,optical communications,material processing,etc. | YANG XU SU CHEN ZHIQIANG WANG BING SUN HONGDAN WAN ZUXING ZHANG | 2019 | Photonics Research2019，7，12： | 5 |
| 20 | The effect of hamstring flexibility on peak hamstring muscle strain in sprinting显示文摘Background:The effect of hamstring flexibility on the peak hamstring muscle strains in sprinting,until now,remained unknown,which limited our understanding of risk factors of hamstring muscle strain injury(hamstring injury).As a continuation of our previous study,this study was aimed to examine the relationship between hamstring flexibility and peak hamstring muscle strains in sprinting.Methods:Ten male and 10 female college students participated in this study.Hamstring flexibility,isokinetic strength data,three-dimensional(3D)kinematic data in a hamstring isokinetic test,and kinematic data in a sprinting test were collected for each participant.The optimal hamstring muscle lengths and peak hamstring muscle strains in sprinting were determined for each participant.Results:The muscle strain of each of the 3 biarticulated hamstring muscles reached a peak during the late swing phase.Peak hamstring muscle strains were negatively correlated to hamstring flexibility(0.1179 ≤ R2≤ 0.4519,p = 0.001) but not to hip and knee joint positions at the time of peak hamstring muscle strains.Peak hamstring muscle strains were not different for different genders.Peak muscle strains of biceps long head(0.071 ± 0.059) and semitendinosus(0.070 ± 0.055) were significantly greater than that of semimembranosus(0.064 ± 0.054).Conclusion:A potential for hamstring injury exists during the late swing phase of sprinting.Peak hamstring muscle strains in sprinting are negatively correlated to hamstring flexibility across individuals.The magnitude of peak muscle strains is different among hamstring muscles in sprinting,which may explain the different injury rate among hamstring muscles. | Xianglin Wan Feng Qu William E.Garrett Hui Liu Bing Yu | 2017 | Journal of Sport and Health Science2017，6，3： | 5 |
