Background Normal adult optic disc rim width follows inferior ≥ superior ≥ nasal ≥ temporal (ISNT) rule.Analysis of the optic disc structural parameters with Heidelberg retina tomograph (HRT) can understand whether ISNT principle is suitable to other optic disc structure parameters.Objective This study was to investigate the characteristics of optic nerve head structure parameters in normal Chinese adults.Methods The parents of twins who participated Guangzhou Twin Eye Study were enrolled in Zhongshan Ophthalmic Center from 2006 June to 2011 August.All subjects received the routine eye examinations,including visual acuity,slit lamp microscope,direct ophthalmoscope examination,auto-refraction examination and HRT Ⅲ examination.All data from the right eyes were collected and analyzed.HRT values from different quadrants of optical nerve head were compared with one-way analysis of variance,and the multiple comparison between quadrants was carried out by Bonferroni test.The differences of optical nerve head parameters in different gender were analyzed using independent sample t test and Bland-Altman test.Results In this study,1672 eyes of 1672 subjects were included,with the 759 male and 913 female persons and average age of (41.8±5.3)years.No significant differences were seen in the disc area (DA)between the superior and inferior,as well as the nasal and temporal quadrants among the subjects (P＞0.05).In addition,there were not significantly different in the rim area (RA) between the superior and nasal disc as well as the rim volume (RV) among the inferior,superior and nasal disc (P＞O.05).However,significant differences were found in the cup area (CA),cup/disk area ratio (C/DAR),cup volume (CV),mean cupdepth (MCD),maximum cup depth (MxCD),height variation contour (HVC),cup shape measure (CSM),mean retinal nerve fiber layer thickness (mRNFLT) and retinal nerve fiber layer cross section area (RNFLcsa) among the different quadrants (P＜0.001).The local differences from only DA and RA complied with an ordination of the ISNT rule.The values of DA,CA,C/DAR,CV,MCD,MxCD from male individuals were higher,but those of the RV,HVC,mRNFLT RNFLcsa were lower in comparison with female individuals.Nevertheless,all the differences were ＜ 0.1 with a maximal mean difference in DA and CA (both 0.07 mm2).Conclusions The optical nerve head configurations measured by HRT have different distributing characteristics in four quadrants in normal adults.Most parameters show the higher values in the inferior and superior than those in nasal and temporal of disc,but DA and RA meet ISNT rule.The differences of most parameters between male and female subjects can be ignored.

Background Heidelberg Retinal Tomograph (HRT) has been widely used in clinical diagnosis of glaucomatous optic neuropathy,importantly,the measurement results of HRT may be affected by myopia.Therefore,studying the effect of different refractive status and axial length on structural parameters of the optic disc is important.Objective This study was to evaluate the influence of refractive error and axial length to optic nerve head parameter measured by HRT.Methods The parents who participate in Guangzhou Twin Study were enrolled in this investigation from July 2006 to August 2011.The regular eye examinations,including visual acuity,slit lamp,fundus,auto-refraction,HRT-Ⅲ and intraocular lens (IOL) Master,were performed on all the subjects.Thc data from right eyes of subjects were collected and analyzed.The linear correlation analysis and multiple linear regression analysis were applied to analyze the correlation between HRT optic papilla configuration parameter and equivalent sphere and ocular axis length.Results A pilot prospective series cases observational study was designed.1748subjects were enrolled in this study.The disc area (DA) (P=0.021),rim area (RA) (P＜0.001),rim volume (RV) (P＜0.001),mean retinal nerve fiber layer thickness (mRNFLt) (P＜0.001) and retinal nerve fiber layer cross section area (RNFLcsa) in the high myopia were greater than those of the emmetropic group,with significant difference between the two groups (P＜0.001).However,the cup area (CA),cup/disk area ratio (C/DAR) and cup volume (CV) were less in the high myopic group than those of the emmetropic group (P=0.004,P＜0.001 and P＜O.001),respectively.In the mild-moderatc myopic group,the RV,mRNFLt and RNFLcsa were greater than those of the emmetropic group (all of the P value less than 0.001),but the numbers of DA,CA,C/DAR,and CV were less than those of the emmetropic group,the differences were significant and their P valuables were 0.038,＜ 0.001,＜0.001 and 0.001 respectively.The differences of structure parameters between the hyperopia group and the emmetropic group were not statistically significant (P＞0.05).The DA,CA,RA,C/DAR,CV,RV,mean cup depth (MCD),maximum cup depth (MxCD),cup shape measure (CSM),mRNFLt and RNTLcsa were (2.04±0.43) mm2,(0.49±0.34) mm2,(1.55 ± 0.34) mm2,0.23-0.13,(0.11 ± 0.12) mm3,(0.45 ± 0.19) mm3,(0.21 ± 0.09) mm,(0.60±0.21) mm,-0.21 ± 0.07,(0.29 ± 0.07) mm and (1.46 ± 0.36)mm2,respectively,in the 1748 eyes of 1748 subjects.No significant correlation was found between the DA value with SE (r=-0.032,P =0.186).However,weaker positive correlations were seen between the CA,C/DAR,CV,MCD,MxCD with SE (r=0.139,0.163,0.130,0.004,0.054,P＜ 0.05) and negative correlation between RA,RV,mRNFLt and RNFLcsa with SE (r =-0.178,-0.331,0.241,-0.239,P＜0.001).With the increase of the ocular axial length,the DA,RA,RV,mRNFLt and RNFLcsa values were enlarged,and the CV value was smaller.With the increase of CA,the RA,C/DAR,CV,RV,MCD,MxCD,CSM and RNFLcsa values elevated,but mRNFLt value was decreased.Conclusions Refractive error is not associated with DA,but the measuring results are different among various refractive groups.Refractive error,ocular axial length and DA affect the measuring result of HRT.

Objective To explore the pathological changes by CT scan on localized thermochemotherapy dur- ing and after the operation of human gliomas.Methods Retrospective analysis was given to the CT scan of 37 pa- tients receiving thermochemotherapy during and after the operation,and the relation of the tumorous cells and mi- crovessels and CT density by EM were analyzed.Changes of tumorous cells and microvessels after localized ther- mochemotherapy on C_6 gliomas in rat were analyzed.Results When the tumor was low dense on CT pattern,less cellular number with increasing the amount of fluid between the cells was demonstrated pathologically.On EM,a lower cellular electron density was observed.The amount of fluid in cytoplasm was increased,the cytoplasm was porous,swelling denaturation was chiefly seen in organelle.If the tumor had mixed density on CT,cellular number was more,the amount of fluid was less.On EM,cellular electron density increased correspondingly,the fluid in cyto- plasm decreased,organdie was aggregated.After thermochemotherapy,the tumor reduced,liquefied,and vanished by CT scan.It could be observed that the tumorous cell become smaller,concentrated and cataclased,finally formed apoprotic bodies and separated from the cell in C_6 gliomas in EM.The tumorous vessels was less,smaller and thinker. Some vessels only could see the base membrane and no endothelioid cells.Conclusion The remaining tumors is van- ished by CT scan.The mechanisms of tumors disappearance proposes to explain that thermochemotherapy can dam- age C_6 glioma cells and microvessels,decrease microvessels density and induce tumor ceils apoptosis.That inhibits tu- morous angiogenesis and proliferation.

Objective To evaluate the efficacy and safety of diacerhein in the treatment of patients with knee osteoarthritis.Methods The efficacy and safety of diacerhein was randomly investigated in 42 pa- tients with knee osteoarthritis using parallel group methodology and a double-dummy technique to ensure dou- ble blind status with respect to diacerhein and control drugs diclofenac.Results Significant changes were ob- served in 20 meters walk pain,knee joint tenderness scale,WOMAC index scale,5F-36 health survey,knee joint swelling scale,compared with baseline(P＞0.05)in both diacerhein and diclofenac group respectively.No difference was found between diacerhein group and diclofenae group.The patient global assessment and physi- cian's global assessment were similar in diacerhein group and diclofenac group(P＞0.05).The side effect was similar in two groups.All of these side effects in gastrointestinal tract appeared to be transient.Conclusion Diacerhein can effectively relieve pain and swelling of knee osteoarthritis,and provides us a new effective and safe approach for treating knee osteoarthritis.

As a member of orphan G protein-coupled receptors (oGPCRs), hGPCRc was cloned from human colon tissue and analyzed by bioinformatic softwares. It was showed that the corresponding amino acids of hGPCRc formed seven-transmembrane domains as the key characteristic of GPCRs. Then, the recombinant GFP-hGPCRc was constructed by fussing hGPCRc into pEGFP-N1 carrying green fluorescent protein (GFP) gene, and CHO-K1 cells were subsequently transfected with the GFP-hGPCRc or pEGFP-N1. The green fluorescence protein expression in the two different transfected cells was observed under the laser scanning confocal microscopy (LSCM). It was showed that green fluorescence protein was distributed in the whole bodies of the cells transfected with pEGFP-N1, but mainly distributed on the plasma membrane and cytoplasm membrane transfected with GFP-hGPCRc. Thus, the localization on the membrane of hGPCRc was accorded with the predication by bioinformatic analysis. The expression analysis of hGPCRc by RT-PCR indicated that hGPCRc was abundantly expressed in heart, kidney, cerebel and colon etc., but absent in liver, cerebra, small intestine and muscle etc. The expressing profile of hGPCRc could provide some useful clues to understanding its effects on embryonic development and physiological functions.
