1.A new method of cataract imaging evaluation
Ophthalmology in China 1994;0(02):-
Photography of slit-lamp biomicroscopy combined with retro-illumination photography is the gold standard in cataract evaluation. However the application is limited due to its complexity and low efficiency. We introduce digital non-mydriatic fundus photography as a new method for cataract screening in patients with visual impairment,which might play an important role in screening low vision and blindness caused by cataract. Two distinguished benefits are found in this method including compatibility for tele-diagnosis,and integration with screening of glaucoma and diabetic retinopathy. Cautions should be made on the photographs in which media opacity derived from other than cataract or low quality photos due to small pupils.
2.THE PROTECTIVE EFFECTS OF FOLIC ACID,VB_6,VB_(12) TO RAT AORTIC ENDOTHELIAL CELLS INJURIED BY DL-HOMOCYSTEINE
Acta Nutrimenta Sinica 1956;0(01):-
Objective:To investigate the cross protective effects of folic acid,VB6,VB12 on rat aortic endothelial cells(RAEC) from injury induced by DL-homocysteine(Hcy).Method:RAEC were cultured in vitro,and the cross effects of folic acid,VB6,VB12 were studied by MTT.According to the results of orthogonal design,the activities of SOD,GSH-PX,NOS and the contents of MDA,NO in the media were compared.Results:The results of orthogonal design indicated that the inhibition of Hcy to RAEC could be relieved by folic acid,VB12 excluding VB6.The interaction existed between folic acid and VB12,as well as VB6 and VB12.The inhibition of Hcy to the enzymes(SOD、GSH-PX、NOS) could be relieved by three vitamin projects.Folic acid,VB12,VB6 could inhibit the reduction of NO and decrease the production of MDA.Conclusion:The simultaneous addition of folic acid,VB6 and VB12 may be an excellent strategy for protection of RAEC injury induced by DL-homocysteine.

Acta Nutrimenta Sinica 1956;0(02):-
Objective: To investigate the effect of DL-homocysteine (Hcy) on expression of VCAM-1 and the adhesion between endothelial cells and monocytes in cultured rat aortic endothelial cells. Method: Rat aortic endothelial cells were cultured in vitro and treated by 0-5.0 mmol/L Hcy for 24 h. The activity of SOD and GSH-Px, the contents of MDA in the medium and the rates of adhesion between endothelial cells and monocytes were determined. The expressions of NF-?b,VCAM-1 protein and the VCAM-1 mRNA were detected by immunocytochemical and reverse transcriptase PCR respectively. Results: Compared with control group and 0.01 mmol/L Hcy , 0.1-5.0 mmol/L Hcy significantly inhibited the activity of SOD and GSH-Px, increased the contents of MDA and the expression of NF-?B and VCAM-1mRNA, enhanced the rates of adhesion between endothelial cells and monocytes. Conclusion: Homocysteine may play a crucial role in atherosclerosis by increasing the expression of NF-?B,VCAM-1mRNA and enhancing the rates of adhesion between endothelial cells and monocytes.

Objective To observe effects of acupoint sticking of Migudan on BGP and Hyp in the patients of primary osteoporosis. Methods By computer random number generating method, the patients were randomly divided into a treatment group treated with acupoint sticking of Migudan, and a control group treated with Gaitianli, 48 cases in each group.

Objective To evaluate video-assisted thoracoscopic sympathectomy(VTS) for the treatment of palmar hyperhidrosis(PH),and to analyze curative efficacies for surgeries on different sympathetic segments.Methods Medline search was done on PubMed and data of randomized controlled trials(RCTs) about comparisons of surgeries on different segments over the past decade were collected.According to the inclusion criterion,relevant articles were screened.Then we extracted data,assessed trail quality,and performed Meta-analysis by using RevMan 5.2 with postoperative compensatory hyperhidrosis(CH) as the main evaluation index.Results A total of 11 RCTs involving 1 413 patients were included,among which all patients underwent bilateral VTS.Ef cacious rates were similar between multiple and single ganglia sympathectomy(97.7% vs 98.8%,P <0.01).However,single-ganglia group showed a lower risk of CH compared to multiple-ganglia group.Meta-analysis suggested that,in the subgroups of the single-ganglia VTS,no significant difference was found between T2/T3 and other segments in the risk of CH [T2 segment vs other segments,RR =1.11,95 % CI(0.99,1.24) ; T3 segment vs other segments,RR =0.99,95% CI(0.89,1.11)].The risk of CH was significantly lower in T4 sympathectomy than in other segments [RR =0.67,95% CI(0.57,0.79)].By comparison of T2,T3 and T4 sympathectomy,we found that low segment had a lower risk of CH than high segment[RR =0.75,95% CI(0.68,0.84)].Conclusion Single-ganglia and low segment sympathectomy can significantly reduce the incidence of CH,and T4 is supposed to be the best segment for the treatment of PH.
