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.

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 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

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.

Objective To study the sedation and amnesia of midazolam in patients with different ages of lumbar epidural anesthesia . Methods From January to July 2015, 235 patients in the first affiliated of xian jiaotong unniversity,who were implemented abdominal surgery under combined spinal epidural anesthesia and American Society of anesthesiologists (ASA) grade was I-II , were divided into three groups:young group (n=70); middle-aged group (n =82); elderly group (n =83).Intraoperative continuous monitoring of respiratory and circulatory function index,and recorded MAP,SpO2, HR before and 5, 15, 30 min after injection.ResuIts MAP, HR and SpO2 of three groups were compared with the same time points pre-and post used of midazolam, there was no significant difference among indicators.; Compared with the same group at different time points, MAP(FYG =9.2547,FMG =12.8181,FOG =17.77)和 SpO2 (FYG =190.3835,FMG =196.2393,FOG =270.5609),there were significant difference.The difference was not statistically significant between HR group and the same group at different time points and forgetting degree and sedation score , but compared with OG,there were significant difference(P<0.05).The total number of adverse reactions in YG group and MG group was less than that of OG group(X2 =11.2516,X2 =10.4491, P<0.05).ConcIusion The effect of the same dose of midazolam on sedation and amnesia in patients with different ages of lumbar epidural anesthesia is different, and the degree of the effect of the elderly patients is significant,but will produce more adverse reactions.Therefore, in the combined spinal epidural anesthesia,it is necessary to consider the patient's individual differences, rational use of sedative and narcotic drugs.
