2Calcium dobesilate for diabetic retinopathy: a systematic review and meta-analysis显示文摘Many randomized clinical controlled trials have confirmed the efficacy and safety of calcium dobesilate in treating diabetic retinopathy(DR).This systematic review critically evaluated the evidence that links calcium dobesilate to DR.In this fixed-effects meta-analysis,a total of 221 pertinent English-language articles published between January 1975 and October 2013 were identified.Systematic searches of PUBMED,Springer Link and the Cochrane Clinical Trials Database were conducted using the keywords 'diabetic retinopathy' and 'calcium dobesilate'.The extracted information included the study design,inclusion and exclusion criteria,setting,sample size,participant mean age,treatment regime,mean change in best corrected visual acuity,laboratory parameters,capillary fragility,intraocular pressure and fundus manifestations based on the findings of fluorescent angiography.The summary statistics indicated that calcium dobesilate was significantly associated with improving retinal microaneurysms(RR: 0.62,95%CI: 0.42?0.90,P=0.01),retinalhemorrhages(RR: 0.39,95% CI: 0.17?0.88,P=0.02); exudates(RR: 0.31,95% CI: 0.12?0.81,P=0.02),reduction of whole blood viscosity(MD: ?0.57 CP,95% CI: ?0.75 to ?0.38,P<0.001),plasma viscosity(MD: ?0.36 CP,95% CI: ?0.63 to ?0.09,P=0.01) and blood cholesterol(MD: ?0.48 mg m L?1,95% CI: ?0.64?0.33,P<0.00001).Intraocular pressure was also significantly reduced(MD: ?5.59 mm Hg,95% CI: ?6.69 to ?4.50,P<0.00001).The results indicate that calcium dobesilate effectively treats DR at the systematic and local ocular levels.ZHANG XinYuan LIU Wei WU ShanShan JIN JingLong LI WeiHong Wang NingLi 2015Science China(Life Sciences)2015,58,1:54
3Mechanism of the reconstruction of aqueous outflow drainage显示文摘Glaucoma is the leading cause of irreversible blindness worldwide. The reconstruction of aqueous outflow drainage (RAOD) has recently been proposed to aid in restoring aqueous outflow drainage in primary open-angle glaucoma. However, the mechanism of RAOD remains to be fully understood. Based on literature review and research studies, the potential mechanisms of RAOD are the following: (i) Circumferential dilation of the Schlemm’s canal (SC) and surrounding collector channels. (ii) Instant formation of microcracks through RAOD procedures. (iii) Formation of more pores, and local detachment between the SC endothelium (SCE) and basement membrane. (iv) Activation of stem cells by constant mechanical stress caused by the tensional suture placed at the anterior part of the SC. (v) Reversal of trabecular meshwork (TM) herniation. (vi) Mobilization of the reserve of the aqueous drainage. (vii) Change of SCE phenotype. (viii) Mechanosensing and mechanotransducing of TM.Chen Xin Ning Tian Meng Li Huaizhou Wang Ningli Wang 2018Science China(Life Sciences)2018,61,5:13
4Pressure balance and imbalance in the optic nerve chamber: The Beijing Intracranial and Intraocular Pressure (iCOP) Study显示文摘To determine the interdependence of intracranial pressure(ICP) and intraocular pressure(IOP) and how it affects optic nerve pressures, eight normal dogs were examined using pressure-sensing probes implanted into the left ventricle, lumbar cistern, optic nerve subarachnoid space in the left eye, and anterior chamber in the left eye. This allowed ICP, lumbar cistern pressure(LCP), optic nerve subarachnoid space pressure(ONSP) and IOP to be simultaneously recorded. After establishing baseline pressure levels, pressure changes that resulted from lowering ICP(via shunting cerebrospinal fluid(CSF) from the ventricle) were recorded. At baseline, all examined pressures were different(ICP>LCP>ONSP), but correlated(P<0.001). As ICP was lowered during CSF shunting, IOP also dropped in a parallel time course so that the trans-lamina cribrosa gradient(TLPG) remained stable(ICP-IOP dependent zone). However, once ICP fell below a critical breakpoint, ICP and IOP became uncoupled and TLPG changed as ICP declined(ICP-IOP independent zone). The optic nerve pressure gradient(ONPG) and trans-optic nerve pressure gradient(TOPG) increased linearly as ICP decreased through both the ICP-IOP dependent and independent zones. We conclude that ICP and IOP are coupled in a specific pressure range, but when ICP drops below a critical point, IOP and ICP become uncoupled and TLPG increases. When ICP drops, a rise in the ONPG and TOPG creates more pressure and reduces CSF flow around the optic nerve. This change may play a role in the development and progression of various ophthalmic and neurological diseases, including glaucoma.Ruowu Hou Zheng Zhang Diya Yang Huaizhou Wang Weiwei Chen Zhen Li Jinghong Sang Sumeng Liu Yiwen Cao Xiaobin Xie Ruojing Ren Yazhuo Zhang Bernhard A.

5Association of three single nucleotide polymorphisms at the SIX1-SIX6 locus with primary open angle glaucoma in the Chinese population显示文摘This study investigated the genetic association of three single nucleotide polymorphisms(SNPs; rs10483727, rs33912345, and rs146737847) at the SIX1-SIX6 locus with primary open angle glaucoma(POAG) in the Chinese population. A total of 866 subjects with POAG(685 high-tension glaucoma(HTG) and 181 normal-tension glaucoma(NTG)) and 266 control individuals were included. Significant genetic association was identified for rs10483727 in HTG(P=0.02; odds ratio(OR)=1.31), NTG(P=7.41×10^(-6); OR=2.71), and POAG(i.e., HTG and NTG combined; P=0.001; OR=1.44). rs33912345 was also significantly associated with HTG(P=0.008; OR=1.36), NTG(P=2.72×10^(-6); OR=2.27), and POAG(P=3.84×10^(-4); OR=1.49). The rare SIX6 mutation, rs146737847, was not found in the subjects enrolled in this study. Stratification by patient age identified that both rs10483727 and rs33912345 were significantly associated with NTG in patients aged above 40 years(P=2.08×10^(-5); OR=2.28), whereas in patients aged between 20–40 years, rs33912345 was significantly associated with NTG(P=0.017; OR=2.06). In HTG, the genetic associations for both rs10483727 and rs33912345 were significant in patients aged between 20–40 years(P=0.006; OR=1.56) but not in those aged above 40 years(P=0.118, OR=1.21 and P=0.042, OR=1.29, respectively). This study replicated the association of POAG with two SNPs at the SIX1-SIX6 locus and demonstrated that SNPs, rs10483727 and rs33912345, are significantly associated with POAG, especially with NTG in patients aged above 40 years.Jinghong Sang Liyun Jia Bowen Zhao Huaizhou Wang Nihong Zhang Ningli Wang 2016Science China(Life Sciences)2016,59,7:9
6A review of trachoma history in China: research, prevention, and control显示文摘Trachoma is one of the most widespread blinding eye diseases, which is harmful to human visual health. The efforts to prevent and control trachoma in China can be divided into three periods, i.e., highly epidemic period, research on pathogenesis and control of trachoma, and blinding trachoma elimination and epidemiological evaluation. In 1956, Prof. Feifan Tang and Xiaolou Zhang first discovered and isolated Chlamydia trachomatis, which clarified the cause of trachoma, and kick-started a fresh chapter in trachoma research, prevention, and control around the world. Although, the prevalence of trachoma differed in different areas, the average prevalence once exceeded 50% and was as high as 90% in some areas before and at early liberation of China. Therefore, the government-led efforts were made to comprehensively prevent and control trachoma, including development of National Plan for the Prevention and Control of Trachoma, nationwide screening and treatment of trachoma, implementation of National Patriotic Health Campaign and improvement of water supply and lavatories. After decades of effort, China reached the goal of eliminating blinding trachoma in 2015. China has gained remarkable achievements in the prevention and treatment of trachoma, making outstanding contributions toward the goal of eliminating trachoma worldwide. The research, prevention, and control of trachoma in China were reviewed in this paper.Ningli Wang Shijing Deng Lei Tian 2016Science China(Life Sciences)2016,59,6:8
7Changes in retinal and choroidal morphology after cerebrospinal fluid pressure reduction: a Beijing iCOP study显示文摘Dear Editor,Glaucoma is a multifunctional neurodegenerative disease and is the leading cause of irreversible blindness. It is characterized by progressive loss of retinal ganglion cells and their axons leading to visual field defects.Lu Liu Xiaoxia Li Hanspeter E Killer Kai Cao Jing Li Ningli Wang 2019Science China(Life Sciences)2019,62,2:7
8Studies of Primary Angle Qosure Glaucoma in China显示文摘The resent researches on primary angle closure glaucoma (PACG) in China were reviewed. The prevalence of PACG (0.41%) in chinese is between the Caucasian and Eskimos, and chronic type is the dominant type in PACG. However, with the economic development and medical care improvements, the prevalence condition of PACG may change; several researches discovered that the mechanism of PACG, especially the chronic type, is not only because of pupil-blocking but also closely related to the mechanism of crowding of peripheral iris and the anterior location of the ciliary body. We supposed that PACG can be divided into several subtypes based on this machnism. Also, we believe that the use of ultrasound biomicroscopy (UBM) and ophthalmic laser in China has promoted the research of PACG and improved the level of prevention and treatment of PACG.

9Molecular characteristics of the omp A gene of serotype B Chlamydia trachomatis in Qinghai Tibetan primary school students显示文摘To study the molecular characteristics of Chlamydia trachomatis, the major outer membrane protein gene(omp A) of C. trachomatis from primary school students with trachoma residing in the Qinghai Tibetan area was sequenced and compared with the same serotype in Gen Bank. In Jianshetang Primary School and Galeng Central Primary School in the Galeng Tibetan Township of Qinghai Haidong Sala Autonomous County, scraped samples were collected from the upper tarsal conjunctiva and lower conjunctival sac of both eyes of 45 students with trachoma, stored at 4°C, and transported to Beijing Tongren Hospital by air within 24 h. The samples were screened for C. trachomatis by real-time PCR. The omp A gene from the C. trachomatis-positive samples was amplified by nested PCR. The serotype was confirmed by National Center for Biotechnology Information(NCBI) BLAST search and homology analysis. The entire omp A gene sequence was compared with the corresponding gene sequences of serotype B strains available in Gen Bank. Of the 45 students aged 6–13 years with trachoma, 26 C. trachomatis-positive students were identified by the initial real-time PCR screening(average age,(9.09±1.63) years; sex ratio, 1.0), accounting for 57.78%(26/45). The cycle threshold values for real-time PCR were 16.79–37.77. Half(13/26) of C. trachomatis-positive students had a bacterial copy number of >105. The compliance rate of the omp A gene sequences with the C. trachomatis serotype B strains in Gen Bank was up to 99%. Two novel genetic mutations were found when the omp A gene was compared with those of the 11 serotype B strains in Gen Bank. The two non-synonymous mutations were located at(i) position 271 in the second constant domain, an adenine(A) to guanine(G) substitution(ACT?GCT), changing the amino acid at position 91 from threonine to alanine(Thr?Ala) in all 26 strains; and(ii) position 887 in the fourth variable domain, a cytosine(C) to thymine(T) substitution(GCA?GTA), changing the amino acid at residue 296 from alanine to valine(Ala?Val) in four of the 26 strains. Six mutations were identified relative to ATCC VR-573. The strains could be divided into two gene clusters according to the mutation at nucleotide position 887: CQZ-1(China Qinghai Tibetan-1) and CQZ-2(China Qinghai Tibetan-2). We thus detected two novel serotype B mutant strains of C. trachomatis among study subjects with trachoma.Xue Li Shaoya Zhang Qingfeng Liang Mei Wang Ailian Hu Xiuyuan Li Benshan Yang Mingxin Zhang Ningli Wang Xinxin Lu 2016Science China(Life Sciences)2016,59,6:6
10Quantitative Real Time Measurement of Iris Configuration in Human Eyes显示文摘Purpose: To evaluate intraobserver and interobserver reproducibility of real time measurement of iris morphology in living human eyes.Methods: Base on the platform of software (Autocad, version 12), we developed an ultrasound biomicroscopy (UBM) image asisstant measuring system. By using the system, we can perform the iris configuration quantitative measurement in living eyes. The measuring parameters including: iris rest length,radius of iris curvature,and the thickness in different parts of iris. Ten anterior segment images of one normal individual were obtained by a single operator to evaluate the intraobserver reproducibility of image capture, and ten times measurement of one image were performed by a single operator to assess the reproducibilityof image measurement. The measurement of three independent observers were compared to investigate interobserver reproducibility in quantitative measurement.

12Immunization with autologous T cells enhances in vivo anti-tumor immune responses accompanied by up-regulation of GADD45β显示文摘Immunization with inactivated autoreactive T cells may induce idiotype anti-idiotypic reactions to deplete autoreac-tire T cells,which are involved in autoimmune diseases.However,it is unknown whether attenuated activated healthyautologous T-cell immunization could increase anti-tumor immune responses.To this end,C57B1/6 mice were immunizedwith attenuated activated autologous T cells.The splenocytes from immunized mice showed a higher proliferative abil-ity than that from naive mice.The special phenotype analysis showed that there were more CDS+T cells and CD62L+T cells in immunized mice after 24 h of culture with 10% fetal calf serum complete medium in vitro(P<0.01).Theseresults demonstrated that this immunization may activate T cells in vivo.Furthermore,the splenocytes from immunizedmice revealed resistance to activation-induced cell death(AICD)in vitro.To further study the relative genes that areresponsible for the higher proliferation and resistance to AICD,the expression of Fas/Fas ligand(FasL)and GADD45βwas measured by real-time PCR.The results indicated that GADD45β transcription was higher in the splenocytes fromimmunized mice than that in the naive mice.In addition,the Fas expression showed a parallel higher,but FasL did notchange obviously.To investigate the biologic functions induced by immunization in vivo,a tumor model was establishedby EL-4 tumor cell inoculation in C57/B1 mice.Mice receiving autologous T-cell immunization had significantly inhibitedtumor growth in vivo(P<0.01).This study implicated that immunization with attenuated activated autologous T cellsenhances anti-tumor immune responses that participate in tumor growth inhibition.Li Wang~(1,2,*) Fang Du~(1,2,*) Qi Cao~(1,2) Huiming Sheng~(1,2) Baihua Shen~(1,2) Yan Zhang~(1,2) Yingna Diao~(1,2) Jingwu Zhang~(1,2) Ningli Li~(1,2) ~1Shanghai diao Tong UniversiO,School of Medicine,280 Chongqing Road,Shanghai 200025,China ~2Shanghai Institute of Immunology,280 Chongqing Road,Shanghai 200025,China 2006Cell Research2006,16,8:5
13Etiological characteristics of chlamydia trachoma conjunctivitis of Primary Boarding School students in the Qinghai Tibetan area显示文摘The aim of this study was to investigate the etiological characteristics of Chlamydia trachomatis conjunctivitis among resident students at primary schools in the Qinghai Tibetan area in order to understand the distribution of C. trachomatis and other pathogenic microorganisms, to detect the isolation rate of infectious pathogens, and to provide an evidence for further targeted efforts in the prevent of sporadic trachoma efforts. From two primary schools in Qinghai Province, ocular samples from 35 students who were clinically diagnosed as trachoma cases and 60 normal controls were obtained by swabbing their upper eyelids and lower conjunctival sacs. Samples were preserved at 4°C and airlifted to Beijing Tongren Hospital within 24 h. Real-time polymerase chain reaction(RT-PCR) was used to screen for C. trachomatis, and nested PCR was used to amplify a fragment of the omp A gene for serotype confirmation. Bacterial cultivation and sensitivity tests were conducted based on the 2015 version of the Clinical and Laboratory Standards Institute. Adenovirus, herpes simplex virus, cytomegalovirus, and Epstein-Barr virus were screened by RT-PCR. Among the 35 students with trachoma, 8 came from the Jianshetang Primary School and 27 came from the Central Primary School. Two novel C. trachomatis B serotypes(Gen Bank accession numbers KU737520 and KU737521) were detected based on a sequence analysis of the omp A gene. Single C. trachomatis infections accounted for 42.86%(9/21) of the cases, and infections with multiple bacteria, particularly Haemophilus influenzae, Staphylococcus aureus, Moraxella catarrhalis, and Streptococcus pneumoniae, accounted for the remaining 57.14%(12/21). Of the 14 C. trachomatis-negative samples, one was positive for adenoviral infection(serotype D) and 13 were positive for bacterial infections(H. influenzae, M. catarrhalis, S. pneumoniae, S. aureus, streptococci other than S. pneumoniae, Staphylococcus epidermidis, Corynebacterium, and Arthrobacterium). In addition to C. trachomatis, the other bacteria and virus that were detected in the boarding students of primary schools in the Qinghai Tibetan area should be emphasized in trachoma prevention and control.Mei Wang Xinxin Lu Ailian Hu Mingxin Zhang Xue Li Shijing Deng Ningli Wang 2016Science China(Life Sciences)2016,59,6:4

15The association of cerebrospinal fluid pressure with optic nerve head and macular vessel density显示文摘The present study aims to investigate the effect of temporary cerebrospinal fluid pressure(CSFP) reduction on optic nerve head(ONH) and macular vessel density(VD) using optical coherence tomography angiography.Forty-four eyes of 44 adults with diagnostic lumbar puncture and CSFP reduction were recruited.Thirty-two eyes of 32 healthy volunteers were controls.ONH and macular VD images were evaluated differences between baseline and after CSFP reduction.The results showed that the mean CSFP decreased from(11.6±2.1) mm Hg to(8.2±3.4) mm Hg(P<0.001).VD in the macular regions decreased significantly after CSFP reduction in the study group(all P<0.05).The control group showed no significant changes in macular VD(all P>0.05).In the study group,decreased VD in the macular parainferior region was associated with CSFP reduction(R^(2)=0.192,P=0.003),the reduction of macular VD in parafoveal(R^(2)=0.098,P=0.018),parainferior(R^(2)=0.104,P=0.021),parasuperior(R^(2)=0.059,P=0.058),paranasal(R^(2)=0.057,P=0.042),paratemporal(R^(2)=0.079,P=0.026) was associated with mean ocular perfusion pressure decrease following CSFP reduction.ONH vessel density did not differ after CSFP reduction(all P>0.05).In conclusion,macular vessel density decreased in association with CSFP reduction.Retinal vessel density in the macular region is more sensitive than that in peripapillary region after CSFP reduction.Xiangxiang Liu Mohamed M.Khodeiry Danting Lin Yunxiao Sun Qing Zhang Jiawei Wang Richard K.Lee Ningli Wang 2022Science China(Life Sciences)2022,65,6:3
16Comparison of time-domain,spectral-domain and swept-source OCT in evaluating aqueous cells in vitro显示文摘Different optical coherence tomography(OCT), both time-domain OCT and spectral-domain OCT, has been used to evaluate anterior chamber cells in previous studies. Recently, commercial swept-source OCT was available. The comparison among three kinds of OCTs have not been done before. Here, we compared their feasibility in discerning aqueous cells in vitro. The peripheral blood was diluted to eight different cell concentrations and was packed into plastic-film bag. Each sample was tested using different scan modes of three OCTs. It was easy to discern aqueous cells from background noise in both Visante AS-OCT and RTVue XR Avanti OCT, but difficult in Casia SS-1000 OCT. The measured blood cell densities in high-resolution corneal cross-sectional scan of Visante AS-OCT, cornea line scan and 3D cornea scan of RTVue XR Avanti OCT were highly correlated with the actual blood cell concentration(Pearson correlation=0.991, 0.989, and 0.993 respectively). The mean adjusted cell densities of cornea line scan(10.46±2.87 spots mm^(-2)) and 3D cornea scan(11.01±2.47 spots mm^(-2)) of RTVue XR Avanti OCT were significantly larger than that of Visante AS-OCT(1.55±1.75 spots mm^(-2))(P<0.01). Our study demonstrated that RTVue XR Avanti OCT, a spectral-domain OCT, is superior to other two OCTs in evaluating aqueous cells.Meng Li Huaizhou Wang Yue Liu Xifang Zhang Ningli Wang 2016Science China(Life Sciences)2016,59,12:3

18Finite element analysis of trans-lamina cribrosa pressure difference on optic nerve head biomechanics: the Beijing Intracranial and Intraocular Pressure Study显示文摘The present study aims to assess the potential difference of biomechanical response of the optic nerve head to the same level of trans-lamina cribrosa pressure difference(TLCPD) induced by a reduced cerebrospinal fluid pressure(CSFP) or an elevated intraocular pressure(IOP). A finite element model of optic nerve head tissue(pre-and post-laminar neural tissue, lamina cribrosa, sclera, and pia mater) was constructed. Computed stresses, deformations, and strains were compared at each TLCPD step caused by reduced CSFP or elevated IOP. The results showed that elevating TLCPD increased the strain in optic nerve head,with the largest strains occurring in the neural tissue around the sclera ring. Relative to a baseline TLCPD of 10 mmHg, at a same TLCPD of 18 mmHg, the pre-laminar neural tissue experienced 11.10% first principal strain by reduced CSFP and 13.66% by elevated IOP, respectively. The corresponding values for lamina cribrosa were 6.09% and 6.91%. In conclusion, TLCPD has a significant biomechanical impact on optic nerve head tissue and, more prominently, within the pre-laminar neural tissue and lamina cribrosa. Comparatively, reducing CSFP showed smaller strain than elevating IOP even at a same level of TLCPD on ONH tissue, indicating a different potential role of low CSFP in the pathogenesis of glaucoma.Yingyan Mao Diya Yang Jing Li Jun Liu Ruowu Hou Zheng Zhang Yiquan Yang Lei Tian Robert N.Weinreb Ningli Wang 2020Science China(Life Sciences)2020,63,12:3

20Apparent ages of suspended sediment and soil erosion of the Pearl River (Zhujiang) drainage basin显示文摘The carbon isotopic composition (Δ 14 C,δ 13 C) and apparent ages of suspended sediment were determined in the Pearl River in the years 1998,2000 and 2005.These results indicate that suspended POC consists mostly of young carbon and some 'old carbon'.Apparent ages of suspended POC range from 540 to 2050 a BP.The apparent ages are older in the Xijiang and Beijiang Rivers,while these values are variable in the Dongjiang River,including old and young samples.The suspended POCδ 13 C values increase with increasing Δ 14 C in the Pearl River,indicating that its source is soil and bedrock from depths under 15 30 cm.Since the organic carbon of the surface soil is quickly decomposed when it enters the rivers,its carbon isotopic characteristics are insignificant in suspended sediment.In the Pearl River drainage basin,there are areas with more severe soil erosion than others.For example,erosion is much more severe in the Xijiang River drainage basin when compared to the light soil erosion in the Dongjiang River drainage basin.WEI XiuGuo SHEN ChengDe LI NingLi WANG FuShun DING Ping WANG Ning GUO ZhiXing LIU KeXin 2010Chinese Science Bulletin2010,55,15:2
