| 1 | Compensation trends of the angulation of first molars:retrospective study of 1403 malocclusion cases显示文摘We investigated the compensatory trends of mesiodistal angulation of first molars in malocclusion cases. We compared differences in the angulation of first molars in different developmental stages, malocclusion classifications and skeletal patterns. The medical records and lateral cephalogrammes of 1 403 malocclusion cases taken before treatment were measured to evaluate compensation of molar angulation in relation to the skeletal jaw. The cases were stratified by age, Angle classification and skeletal patterns. Differences in the mesiodistal angulation of the first molars were compared among the stratifications. We observed three main phenomena. First,angulation of the upper first molar varied significantly with age and tipped most distally in cases aged,12 years and least distally in cases aged.16 years. The lower first molar did not show such differences. Second, in Angle Class II or skeletal Class II cases, the upper first molar was the most distally tipped, the lower first molar was the most mesially tipped, and opposite angulation compensation was observed in Class III cases. Third, in high-angle cases, the upper and lower first molars were the most distally tipped, and opposite angulation compensation was observed in low-angle cases. These data suggest that the angulation of the molars compensated for various growth patterns and malocclusion types. Hence, awareness of molar angulation compensation would help to adjust occlusal relationships, control anchorage and increase the chances of long-term stability. | Hong Su Bing Han Sa Li Bin Na Wen Ma Tian-Min Xu | 2014 | International Journal of Oral Science2014，6，3： | 22 |

| 3 | Effects of size variation and spatial structure on plastic response of plant height to light competition显示文摘Plants only interact with neighbors over restricted distances,so local conditions are of great significance for plants.In this study,a spatially-explicit,individual-based model was constructed to explore the effects of size variation and spatial structure on adaptive plasticity of plant height in response to light competition.In the model a plant maintains its height at an optimal value in order to maximize its growth rate,and this optimal height increases with the increase of the intensity of light competition experienced by the individual plant.When the spatial pattern of the population is non-uniform or there is size variation among individual plants,the height growth curves of individuals different from each other vary due to the differences in the local light environment,and there is also variation in the allocation of photosynthate to height growth among the individual plants.There is no ESS height or height growth strategy on which all plants will converge.Our results indicate that the plasticity of plants' height growth reactions to the light competition should be considered at the individual level and they argue strongly for the importance of the spatial pattern and neighborhood effects in generating the diversity of heights and height growth strategies in plant population. | CHEN ShuYan ZHANG JiaLin JIA Peng XU Jin WANG Gang XIAO Sa | 2010 | Chinese Science Bulletin2010，55，12： | 8 |
| 4 | 复杂性长段尿道狭窄与勃起功能之间的关系:初步调查和描述性研究显示文摘本研究的目的在于评估超长尿道狭窄患者尿道重建术后的勃起功能情况。该研究我们共纳入65名患者,其中根据每个患者具体的尿道狭窄情况,实施个体化的尿道重建术式。我们在术前、术后对每个病人都进行阴茎勃起功能的评估。尿道狭窄的长度及部位、首次诊断到最终的手术时间间隔也在记录的范围之内。随访患者术后3、6、12个月IIEF.5评分、QOL评分及最大尿流率,并与术前相应情况进行比较分析。结果显示术后3、6和12个月患者QOL评分及最大尿流率相较于术前有显著改善(P〈0.05)。多段尿道狭窄患者术后3个月的勃起功能有明显下降(P〈O.05),但在术后6、12月的两个随访点时,其勃起功能有不同程度的恢复。前尿道狭窄患者在术后3、6、12月的随访时间点上IIEF-5评分均高于同期的多段尿道狭窄术后患者。在术后勃起功能障碍患者与术后勃起功能正常患者之间,年龄和首次诊断到最终的手术间隔时间没有明显的差异,但我们发现IIEF-5评分和尿道狭窄的位置存在线性回归关系。重建手术方面,其本身对长段尿道狭窄患者术后的勃起功能影响有限。尿道狭窄的位置,尤其是波及到后尿道,是术后对勃起功能产生影响的因素。 | Hong Xie Yue-Min Xu Qiang Fu Ying-Long Sa YongQiao | 2015 | Asian Journal of Andrology2015，17，2： | 7 |

| 6 | Evaluation of erectile function after urethral reconstruction:a prospective study显示文摘We conducted a prospective study of erectile dysfunction(ED)after urethral reconstructive surgery,using the 5-item International Index of Erectile Function(IIEF-5),the Sexual Life Quality Questionnaire(SLQQ)and the Quality of Life Questionnaire(QoLQ).Between January 2003 and July 2007,125 male patients with urethral strictures underwent urethroplasty,and pre-and post-surgery erectile function was assessed using these three questionnaires.A formula to predict the probability of ED after urethroplasty was derived.At 3 months post-operatively,there was a significant decrease in IIEF-5(16.57±7.98)and SLQQ scores(28.71±14.84)compared with pre-operative scores(P<0.05).However,the IIEF-5 scores rebounded at 6 months post-operatively(17.22±8.41).Logistical regression analysis showed that the location of the urethral stricture,the recurrence of strictures and the choice of surgical technique were predictive of the post-operative occurrence of ED.This study identified the clinical risk factors for ED after urethroplasty.Posterior urethral stricture and end-to-end anastomosis were found to have a strong relationship with erectile function.The logistical model derived in this study may be applied to clinical decision algorithms for patients with urethral strictures. | Hong Xie Yue-Min Xu Xiao-Lin Xu Yin-Long Sa Deng-Long Wu Xin-Chi Zhang | 2009 | Asian Journal of Andrology2009，11，2： | 6 |

| 8 | Formation mechanism of propagated sensation along the meridians,as verified by cortical somatosensory-evoked potential topographic maps显示文摘The peripheral driver stimulating theory states that as a driver passes along a certain meridian during acupuncture;the driver provokes nerve sense devices along the meridian,resulting in the nerve impulse entering the central nervous system.Accordingly,volunteers have reported propagated sensations along the meridians (PSM).The present study was designed to utilize a cortical somatosensory-evoked potential (CSEP) topographic map for determining whether stimulation expansion occurs in somatosensory area I when sensation was provoked in individuals with obvious PSM.The sensation was blocked by mechanical compression,and the sensation was imitated in individuals without PSM.Results revealed a red,high-potential signal in the representative area of the lower limbs in individuals with obvious PSM symptoms when the Gall Bladder Meridian (GBM) sensation passed to the head and face.This representative area was near the middle line of the CSEP topographic map,and a red,high-potential signal,which jumps over the representative area of the upper limbs,also appeared in the representative face area,which was at the external region of the CSEP topographic map.However,in individuals exhibiting no PSM,only a red high-potential signal appeared in the representative lower limb area.When Hegu (LI 4) was stimulated in individuals without PSM,an obvious evoked response appeared only in the representative upper limb area.However,when Hegu was stimulated in individuals exhibiting PSM,the response area was larger in the representative upper limb area and extended to the representative face area.When Guangming (GB 37) was stimulated in PSM individuals,the face representation response disappeared and was confined to a foot representation of the somatosensory area I when PSM was blocked by mechanical pressure.Results suggested that mechanical compression blocked PSM,and corresponding changes were exhibited in the CSEP topographic map.These results provide compelling evidence for the hypothesis that peripheral driver stimulation is the key element in producing PSM. | Jinsen Xu Xiaohua Pan Shuxia Zheng Xianglong Hu Zheyan Sa | 2011 | Neural Regeneration Research2011，6，6： | 3 |
| 9 | Relationship between virological response and FIB-4 index in chronic hepatitis B patients with entecavir therapy显示文摘AIM: To investigate whether long-term low-level hepatitis B virus(HBV) DNA influences dynamic changes of the FIB-4 index in chronic hepatitis B(CHB) patients receiving entecavir(ETV) therapy with partial virological responses.METHODS: We retrospectively analyzed 231 nucleos-(t)ide(NA) na?ve CHB patients from our previous study(NCT01926288) who received continuous ETV or ETV maleate therapy for three years. The patients were divided into partial virological response(PVR) and complete virological response(CVR) groups according to serum HBV DNA levels at week 48. Seventy-six patients underwent biopsies at baseline and at 48 wk. The performance of the FIB-4 index and area under the receiver operating characteristic(AUROC) curve for predicting fibrosis were determined for the patients undergoing biopsy. The primary objective of the study was to compare the cumulative probabilities of virological responses between the two groups during the treatment period. The secondary outcome was to observe dynamic changes of the FIB-4 index between CVR patients and PVR patients.RESULTS: For hepatitis B e antigen(HBe Ag)-positive patients(n = 178),the cumulative probability of achieving undetectable levels at week 144 was 95%and 69% for CVR and PVR patients,respectively(P < 0.001). In the Cox proportional hazards model,a lower pretreatment serum HBV DNA level was an independent factor predicting maintained viral suppression. The cumulative probability of achieving undetectable levels of HBV DNA for HBe Ag-negative patients(n = 53) did not differ between the two groups. The FIB-4 index efficiently identified fibrosis,with an AUROC of 0.80(95%CI: 0.69-0.89). For HBe Ag-positive patients,the FIB-4 index was higher in CVR patients than in PVR patients at baseline(1.89 ± 1.43 vs 1.18 ± 0.69,P < 0.001). There was no significant difference in the reduction of the FIB-4 index between the CVR and PVR groups from weeks 48 to 144(-0.11 ± 0.47 vs-0.13 ± 0.49,P = 0.71). At week 144,the FIB-4 index levels were similar between the two groups(1.24 ± 0.87 vs 1.02 ± 0.73,P = 0.06). After multivariate logistic regression analysis,a lower baseline serum HBV DNA level was associated with improvement of liver fibrosis. In HBe Ag-negative patients,the FIB-4 index did not differ between the two groups.CONCLUSION: The cumulative probabilities of HBV DNA responses showed significant differences between CVR and PVR HBe Ag-positive CHB patients undergoing entecavir treatment for 144 wk. However,long-term low-level HBV DNA did not deteriorate the FIB-4 index,which was used to evaluate liver fibrosis,at the end of three years. | Ni Li Jing-Hang Xu Min Yu Sa Wang Chong-Wen Si Yan-Yan Yu | 2015 | World Journal of Gastroenterology2015，21，43： | 3 |
| 10 | Prevalence trend and risk factors for anemia among patients with human immunodeficiency virus infection receiving antiretroviral therapy in rural China显示文摘OBJECTIVE: To estimate the prevalence trend and risk factors for anemia in patients with human immunodeficiency virus(HIV) infection receiving antiretroviral therapy(ART) in rural China.METHODS: We conducted cross-sectional studies among the same population in 2010, 2012, and2014, based on data from standard medical record registers. Factors associated with anemia were evaluated using a logistic regression model.RESULTS: The number of patients with HIV infec-tion included in each cross-sectional study was1456 in 2010, 1531 in 2012, and 1567 in 2014, and the prevalence of anemia was 44.3%, 34.7%, and27.6%, respectively. The prevalence of anemia was lower in female patients in 2010 [odds ratio(OR)0.68; 95% confidence interval(CI) 0.55-0.85]; however, there was no difference by sex in 2012(OR0.90; 95% CI 0.72-1.11) and 2014(OR 1.05; 95% CI0.84-1.32). Patients with a higher level of education had a lower risk of anemia in 2014(OR 0.72; 95% CI0.56-0.92), but there was no difference in 2010(OR1.00; 95% CI 0.79-1.25) and 2012(OR 0.99; 95% CI0.79-1.24). Patients who had received a longer duration of ART had a higher risk of anemia in 2014(OR1.74; 95% CI 1.15-2.64), but there was no difference in 2010 and 2012(P > 0.05). Patients receiving Traditional Chinese Medicine(TCM) therapy had a lower risk of anemia.CONCLUSION: The prevalence of anemia among patients with HIV infection receiving ART decreased between 2010 and 2014 in Henan Province but was still higher than the prevalence in the general population of China. TCM therapy can potentially decrease the risk of anemia among patients with HIV infection. | Jin Yantao Liu Sa Yuan Jun Meng Xiangle Guo Huijun Xu Liran Xu Qianlei | 2019 | Journal of Traditional Chinese Medicine2019，39，1： | 2 |

| 12 | Collisionless tool orientation smoothing above blade stream surface using NURBS envelope显示文摘In five-axis machining,tool orientation above a blade stream surface may lead to tool collision and a decrease in workpiece rigidity.Hence,collisionless tool orientation smoothing(TOS)becomes an important issue.On the basis of a constant scallop height tool path,the triangular facets in the faces,vertices format are constructed from cutter contact(CC)using the Voronoi incremental algorithm.The cutter location(CL)points candidate set is represented by an oblique elliptic cone whose vertex lies at CC using NURBS envelope.Whether the CL point is above its CC is judged by the dot product between the normal vector and the point on triangulation nearest to the CL point.The curvatures at CC are obtained by fitting a moving least square(MLS) quadratic patch to the local neighborhood of a vertex and calculating eigenvectors and eigenvalues of the Hessian matrix.Triangular surface elastic energy is employed as the weight in selection from the NURBS envelope.The collision is judged by NURBS surface intersection.TOS can then be expressed by selecting a CL point for each CC point and converted into a numerical control(NC)code automatically according to the postprocessor type of the machine center.The proposed method is verified by finishing of a cryogenic turboexpander impeller of air separation equipment. | Jing-hua XU Shu-you ZHANG Jian-rong TAN Ri-na SA | 2013 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2013，14，3： | 2 |
| 13 | Novel ATP8B1 mutation in an adult male with progressive familial intrahepatic cholestasis显示文摘Progressive familial intrahepatic cholestasis type 1 is a rare disease that is characterized by low serum γ-glutamyltransferase levels due to mutation inATP8B1.We present a 23-year-old male who experienced persistent marked pruritus for eighteen years and recurrent jaundice for thirteen years,in addition to cholestasis that eventually became fatal.Genetic sequencing studies of the entire coding(exon) sequences of ATP8B1 and ABCB11 uncovered a novel heterozygous missense 3035G>T mutation(S1012I) and a synonymous 696T>C mutation in ATP8B1.The patient's progression was associated with not only impaired familial intrahepatic cholestasis 1(FIC1) function but also impaired bile salt export pump expression due to the impaired FIC1 function.Our findings show that patients with intermittent cholestasis can develop progressive liver disease even after several decades and require regular follow up. | Bao-Cheng Deng Sa Lv Wei Cui Rui Zhao Xu LU Jian Wu Pei Liu | 2012 | World Journal of Gastroenterology2012，18，44： | 2 |
