Background Researches showed that the content of nitric oxide (NO) and nitric oxide synthetase (NOS) increases in blood,aqueous humor and tear of cataract patient.But the function of NO and NOS in cataract formation is still elusive.Objective The aim of this study was to explore the prevention and treatment effect of NOS inhibitor,1-nitro-arginine methyl ester (L-NAME),on galactose cataract.Methods Sixty clean three-week-old Wistar rats were equally and randomly divided into 3 groups.0.9% Normal saline solution (30 ml/kg) was subcutaneously injected every day for 30 days in the rats of the control group,and 50% of D-galactose solution (30 ml/kg) was used in the rats of the model and L-NAME group at the same way.L-NAME eye drops was simultaneously administered in the L-NAME group 3 times per day for 30 days.The eyes of the rats were examined under the slit lamp in 10,20 and 30 days,and the degree of lens opacification was scored.Lenses of the rats were obtained at the end of this experiment for the detect of NO,NOS contents.Flow cytometry was used to assay the caspase-3 level of rat lens.Repeated measurement two factor analysis of variance was used to analyze the difference of lens opacification scores in different groups and different time points,and one-way ANOVA was used to analyze the differences of NO,NOS and caspase-3 contents in lens among the groups.Results Lens opacification appeared in 10 days after injection of 50% D-galactose solution in the rats of the model group and L-NAME group.Lens opacification score was higher among the different groups and different time points (Ftime =435.251,P =0.000 ;Fgroup =395.120,P=0.000).NO content in the lens was (0.45±0.15) μmol/g,(2.67 ± 0.47) μmol/g and (1.68±0.34) μmol/g in the control group,model group and L-NAME group,showing a significant difference (F=58.872,P=0.000).The NOS contents in the lens was (0.0160±0.0020) U/ml,(0.0370±0.0040) U/ml and (0.0270±0.0010) U/ml in the control group,model group and L-NAME group,showing a significant difference (F =66.174,P=0.000).Caspase-3 contents in the lens was (339.4 ± 37.9),(697.7 ± 46.5) and (650.7 ± 53.1),Showing a significant difference among them (F =100.005,P =0.000).Conclusions The increase of NO,NOS and caspase3 levels are associated with lens opacification.Topical administration of L-NAME eye drops can down-regulate NOS content in lens,reduce the NO formation and inhibit the apoptosis of lens epithelial cells.

Aim To explore the pharmacological mechanism and the effects of polysaccharide sulfat(PSS) on cardiovascular diseases induced by type 2 diabetes mellitus(DM) through observing the risk factors.Methods Type 2 diabetic animal model was established by high-sugar and high-fat diets,combined with injection of small amount streptozotocin(STZ 20 mg?kg-1,iv).Adult male wistar rats were divided into five groups: normal control group,model group,polysaccharide sulfate group,metformin group and lovastatin group.They were treated with exact medicne for 8 weeks,but control group and model group were treated with 0.9% Nacl.During this process,FBG and serum lipid concentrations were measured.22 weeks later,the rats were sacrificed.The activity of tissue-type plasminogen activator(t-PA) and plasminogen activator inhibitor type-1(PAI-1) were detected by chemical methods.The aortas were collected for histopathlogical,immunohistochemical and Western blot studies.Results FBG concentrations and serum lipid(TC,TG,LDL) levels decreased in PSS group as compared from those of model group(P

Objective To study the effects of emergency operation with 2~5 cm incision to treat fresh closed heel tendon disjunction.Method 23 cases of fresh closed heel tendon disjunction were operated in post-injury 3~12 hours and the incisions were 2~5 cm long. Results None of these cases was complicated with wound infection or cutaneous necrosis.The follow-up was from 6 months to 6 years,averaging 2.2 years;in which,according to the Arner-Lindholm standards,20 were excellent,3 were good.Conclusion A satisfactory effect can be obtained through the smaller incision to treat the fresh closed heel tendon disjunction.

Objective To explore the effect of posterior internal fixation surgery with pedicle screw/rod instrument system in the treatment of thoracic vertebrae fracture-dislocation complicated with a severe thoracic injury. Methods In the 8 cases examined, the range of injury was from T5 to T9, including 1 case of compression fracture-dislocation and 7 cases of burst fracture-dislocation according to Hanley and Eskey’ s classification. According to Frankle’ s classification, 4 were grade A, 3 were grade B, 1 was grade C. All cases were complicated with multiple fractures of bilateral ribs, pulmonary contusion and haemothorax. After the pathogenic condition being stable, reduction and internal fixation were performed with the posterior surgery pedicle screw/rod instrument system. In 5 cases, spinal canal anterolateral decompression was performed homeochronously. The intervals between accidents and operation were 3 to 9 days. Results Operations were performed safely in all patients. The reposition of the alignment and height of vertebraes was good. Postoperative CT scanning showed: in 2 cases, bone block occupied about 10% volume of vertebral canal, and 1 was 50%. The follow-up were 4~36 months, averaging 15 months. No postreduction disposition, internal fixation loosening or breakage occurred. The Frankel’ s classification of neurological function was improved by 1 grade on average. Conclusions After a positive treatment of thoracic injury, it is safe and feasible to treat the fresh thoracic vertebrae fracture-dislocation with the posterior surgery pedicle screw/rod instrument system, and the curative effects are satisfied.

ObjectiveTo investigate the value of 18F-FDG SPECT myocardial imaging in evaluating haemodynamic change,treatment outcome and prognosis for idiopathic pulmonary arterial hypertension (IPAH).MethodsAll 24 patients with IPAH underwent 18 F-FDG SPECT myocardial imaging.Right ventricle/left ventricle (RV/LV)-FDG uptake was calculated by ROI method drawing over the central areas of left and right ventricular free walls.All patients underwent right heart catheterization within 3 days after imaging studies.Mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance (PVR) were recorded.After six month pharmaceutical treatment,15 IPAH patients were re-examined with 18F-FDG SPECT myocardial imaging followed by repeated right heart catheterization within 3 days.Plasma N-terminal pro-brain naturetic peptide (NT-proBNP) and endothelin-1 ( ET-1 ) were measured in 17 patients using electrochemiluminescent immunoassay and enzyme immunoassay respectively.All patients were followed up for 12 months at least.Correlations between RV/LV-FDG uptake and mPAP and PVR were determined by simple linear regression analysis.Change of RV/LV-FDG before and after treatment was calculated using Student's t-test.Survival in groups with RV/LV FDG uptake ≥ 1.15 and RV/LV-FDG uptake < 1.15 were compared using Log-rank test.ResultsSignificant correlations were found between RV/LV-FDG uptake and mPAP (r =0.562,P < 0.01 ),and between RV/LV-FDG uptake and PVR ( r =0.574,P < 0.01 ).There were no significant correlation between RV/LV-FDG uptake and NT-proBNP( r =0.18 1,P > 0.05 ),but a significant correlation between RV/LV-FDG and ET-1 was observed (r =0.669,P < 0.01 ).The RV/LV-FDG uptake in patients with positive treatment outcome ( n =6) decreased from 1.38 ± 0.52 to 0.92 ±0.26 (t =4.018,P < 0.05) after 6 months treatment.In contrast,no significant change of RV/LV-FDG uptake was seen in those patients (n =9) with negative treatment outcome ( t =1.861,P > 0.05 ).The mean follow-up time was (21 ±8) months.Mean survival time for the patients with RV/LV- FDG uptake ≥ 1.15was 28 months (95% confidence interval:24-32 months),which was significantly lower than 34 months survival (95% confidence interval:33-35 months) for the patients with RV/LV-FDG < 1.15 (x2 =3.956,P <0.05 ).Conclusions Detection of right ventricle myocardial glucose metabolism level with 18F-FDG SPECT may be a practical method for evaluating haemodynamic change,treatment outcome and prognosis of IPAH.
