AIM:To explore the clinical effect of capsule membrane phacoemulsification and capsular bag in phacoemulsification in treatment of hard nuclear cataract with high myopia.
METHODS:A total of 297 patients(322 eyes) with hard nucleus cataract(Ⅳ-Ⅴ grade nucleus) and high myopia were selected from Mar. 2014 to Mar. 2016 in our hospital. They were randomly divided into the observation group with 149 cases(162 eyes) and the control group with 148 cases(160 eyes). The observation group received capsule membrane phacoemulsification and the control group received capsular bag in phacoemulsification. The therapeutic effect and safety of patients in two groups were compared. The comparison of phacoemulsification time, energy parameters and corneal endothelial cell density used t-test, post-operative visual acuity and the occurrence of complications were tested by Chi-square test.
RESULTS: The harder the nucleus was, the longer the phacoemulsification time and higher the average phacoemulsification energy was, and the differences were statistically significant(P<0. 05). The phacoemulsification time and energy parameters of the observation group were significantly lower than that of the control group( P<0. 05 ). One month after operation, the postoperative visual acuity in two groups was significantly higher than the visual acuity at 1d after operation(P<0. 05). But there was no statistical significance on the visual acuity at 1mo after operation between two groups ( P> 0. 05 ). After operation, the density of corneal endothelial cell in two groups was significantly lower than the density before operation ( P < 0. 05 ). But there was no statistical significance on the density of corneal endothelial cell after operation between two groups ( P > 0. 05 ). The intraoperative complication rate of observation group was significantly lower than that of the control group ( P<0.05 ) , but there was no statistical significance on postoperative complication rate between two groups ( P>0. 05). CONCLUSION: For the treatment of hard nuclear cataract with high myopia, capsule membrane phacoemulsification and capsular bag in phacoemulsification have similar effect, but capsule membrane phacoemulsification has better safety.

Objective: To study the correlations between galectin-3, soluble ST2 (sST2) levels and chronic heart failure (CHF) classiifcation, traditional HF indicator and short-term death in relevant patients. Methods: This research included 2 groups: CHF group, containing 142 relevant patients treated in our hospital from 2014-02 to 2015-10 and Control group, containing 85 normal subjects from physical examination at the same period of time. Based on NYHA criterion, the patients were classiifed in NYHA grade II, III and IV respectively. Blood levels of N-terminal brain natriuretic peptide (NT-ProBNP), high-sensitivity C reactive protein (hs-CRP) and ultrasonic morphology were examined upon admission; protein expressions of galectin-3 and sST2 were assessed by ELISA. Results: The patients with NYHA grade III and IV had increased levels of galectin-3 and soluble sST2; galectin-3, sST2 were positively related to NT-ProBNP, hs-CRP and LVEDD, while negatively related to LVEF. Logistic regression analysis indicated that galectin-3 and sST2 were related to short-term death in CHF patients,P<0.05. Area under ROC curve of galectin-3 and sST2 for diagnosing CHF were 0.738 and 0.771,P<0.01. Conclusion: Galectin-3 and sST2 levels were related to traditional HF indicator and could be used for CHF diagnosis in relevant patients.

[Objective]To investigate the effects of alendronate(ALN)on subchondral bone and articular cartilage in the rat osteoarthritis model induced by anterior cruciate ligament transaction(ACLT).[Method]Twenty-four three-month-old female Sprague-Dawley rats were divided randomly into three groups:Sham group(n=8),ACLT+NS group(n=8) and ACLT+ALN group(n=8)(20 ?g?kg-1?2 d-1 subcutaneous injection for 12 weeks).Bone mineral density(BMD) measurement and bone histomorphometric analysis were made for the subchondral bone of right distal femur and proximal tibia in all rats at 12 weeks post surgery.Degree of cartilage degeneration was scored by Mankin scoring system.Immunostaining for matrix metalloproteinase 13(MMP-13) was performed to investigate the effect of ALN on cartilage matrix loss.[Result]BMD of the subchondral bone in the ACLT+NS group were significantly lower than those in the Sham group and the ACLT+ALN group(P

40%)were observed in HLA CREGs matching and outcome of post-transplantation.Results Patients with 0,1,2 or 3 mismatching(MM) of HLA CREGs+DR were 4(28%), 6(44%)and 4(28%)cases respectively according to the the rule of CREGs matching and no case had 3～6 MM.However the cases of 0,1,2,3 and 4 MM were 1(7%),3(21%),5(36%)and 5(36%)respectively by the standard of conventional HLA antigen matching,without 4～6 MM and only 4 cases had shared 0～1MM.Only 9 patients were developed into acute rejection, and were reversed by OKT3 treatment after transplantation.Renal function was returned to normal in all patients.Conclusions Using CREGs matching criteria would significantly increase the chance of recipients to receive well-matched kidney and provide more chance for waiting recipients.Suitable HLA matching could play an important role in reducing the incidence of acute rejection and improving graft survival in sensitized patients.

Objective To investigate the protective effect of trichostatin-A (TSA) on cerebral ischemia/reperfusion injury via Janus kinase/signal transducer and activator of transcription (JAK/STAT) signal pathway.Methods 36 male SD rats were randomly (random number) divided into 3 groups:shamoperated group,ischemia/reperfusion (I/R) group and TSA group.Rat model of middle cerebral artery occlusion/reperfusion (MCAO) was established using a modified filament method.No occlusion was applicated to the sham-operated group.TSA group was injected with TSA 0.05 mg/kg via penile vein,20 minutes before operation.Reperfusion was carried out 24 hours after modeling.Longa 5 score was used to assess the neurological function,and TTC staining was applied to calculate the percentage of cerebral infarction area,The expression of JAK2 and p-JAK2 proteins was detected by Elisa.Results The low expression of JAK2 was observed in each group,and there was no statistical difference between groups (P =0.266).Compared with I/R group,TSA group had lower score in cerebral ischemia-reperfusion injury assessment (P=0.019),smaller area of cerebral infarction (P ＜0.01),reduced expression of p-JAK2 (P =0.009),all of which were of significant difference.Condusions TSA can reduce the cerebral ischemia/reperfusion injury via JAK/STAT signal pathway by down regulating p-JAK2 expression.

Objective: To express glycosyl-phosphatidylinositol (GPI) modified Met- RANTES fusion protein on Chinese hamster ovary (CHO) cells and to develop a novel immunosuppressant GPI anchored form of Met-RANTES. Methods: The eukaryotic expression vector PEF/GPI-Met-RANTES were constructed and transfected into CHO cells by electroporation. The transfectants were selected with methotrexate (MTX). Expression of the recombinant protein was assessed by flow cytometric analysis, cell immunofluorescence staining and immunogold electron microscopy. Results: The chimeric molecules of GPI anchored form of Met-RANTES including the whole reading frame were constructed, and the sequence was identical to the designed sequence. GPI anchored form of Met-RANTES was stably expressed on CHO- DHFR- cells. Conclusion: A large amount of GPI modified Met-RANTES fusion protein was expressed on CHO cells. GPI anchored form of Met-RANTES may be used as novel immunosuppressant for suppressing reaction in graft rejection.

Purpose To establish rabbit VX2 tumor model and to explore the relation between perfusion parameters and the expression of the VEGF in the portal vein VX2 implanting tumor emboli. Materials and Methods VX2 tumor was implanted in the portal vein of eight experimental rabbits. Multi-slice CT (MSCT) perfusion scan was performed after tumor formation to measure and compare portal vein tumor thrombus, hepatic blood lfow (HBF) near tumor foci and far away from tumor foci, hepatic blood volume (HBV), probability of surface area product (PS) and mean transit time (MTT). The VX2 tumor emboli were then resected to analyze the relationship between the liver perfusion parameters and VEGF expression using immunohistochemical method. Results MSCT liver perfusion parameters were not statistically signiifcant between foci close to or far away from the tumor (P>0.05). The HBF, HBV and PS within the tumor emboli were higher than that in hepatic parenchyma (P<0.05) and the MTT was higher (P<0.05). There was positive correlation (r=0.711, 0.646 and 0.626, P<0.05) between the HBF, HBV and PS of portal vein VX2 tumor emboli and VEGF expression, and there was negative correlation between MTT and VEGF expression (r=-0.565, P<0.05). Conclusion MSCT perfusion parameters in the portal vein VX2 implanting tumor emboli and the expression of VEGF are positively related. MSCT can evaluate the angiogenesis of portal vein VX2 implanting tumor emboli.

Objective To detect the expression of E-cadherin and ?-catenin in breast carcinoma and analyze the relationship between E-cadherin and ?-catenin and the clinicopathological features. Methods The expression of E-cadherin and ?-catenin in breast cancer, paracarcinoma breast tissue, simple mastoplasia and atypical mastoplasia were detected by immunohistochemical method and the results were compared. Results The abnormal expression rates of E-cadherin and ?-catenin in breast cancer tissue were 51.9% and 61.1 %,respectively. Abnormal expression of E-cadherin was significantly correlated with histological grade. Abnormal expression of ?-catenin was significantly correlated with TNM staging, axillary lymph nodes metastasis and postoperative distant metastasis. COX multiple factor analysis showed that neither E-cadherin nor ?-catenin expression was an independent indicator for the prognosis of breast cancer. Conclusions Abnormal expressions of E-cadherin and ?-catenin are correlated with occurrence and development of breast carcinoma. Abnormal expressions of E-cadherin and ?-catenin are good indicators to judge invasion and metastasis of breast carcinoma.
