AIM: To investigate the clinical effect of cataract combined lens dislocation greater than 2 quadrants` patients after having phase I intracapsular cataract extraction and anterior vitrectomy,postoperative corrected vision greater than 0.3,and then taking phase II small incision suture-fixation of intraocular lens suspension.METHODS: Totally 34 cases with cataract combined lens dislocation greater than 2 quadrants had been treated in our hospital from July 2014 to December 2016.We investigated their 1wk,1 and 3mo postoperative complications and the uncorrected visual acuity,best corrected visual acuity,intraocular pressure,corneal astigmatism who took phase II small incision suture-fixation of intraocular lens suspension with corrected vision greater than 0.3 after having phase I intracapsular cataract extraction and anterior vitrectomy.RESULTS: Along with the recovery time extension,patients` uncorrected visual acuity and best corrected visual acuity increased obviously than preoperative in each phase.On the 3mo postoperatively,the best corrected visual acuity of 1 eyes was between 0.3 and 0.1,8 eyes was between 0.5 and 0.3,16 eyes was between 0.7 and 0.5,and 9 eyes was better than 0.7.The best corrected visual acuity was achieved or near the best corrected visual acuity before surgery.Intraocular pressure rechecked became in the normal range at 1wk,1 and 3mo postoperative.Surgery did not significantly increase the corneal astigmatism.CONCLUSION: It is a safe and effective way in improving eyesight effectively,with stable intraocular pressure and fewer complications towards cataract combined lens dislocation greater than 2 quadrants` patients having phase I intracapsular cataract extraction and anterior vitrectomy,whose postoperative corrected vision greater than 0.3,and then phase II small incision suture-fixation of intraocular lens suspension.

Objective To analysis the varying degrees of the M protein staining after immunofixation electrophoresis(IFE)and study its applications in clinical diagnosis.Methods 196 cases of clinical serum samples were tested by using IFE,we analyzed the positive electrophoretic bands of M protein and performed statistical analysis by using SPSS17.0.The M proteins were analyzed ret-rospectively.Results 103 patients were diagnosed with monoclonal gammopathy in 196 patients with positive M protein bands,in-cluding 96 cases of multiple myeloma(MM)and 7 cases of other monoclonal gammopathy;93 patients were non-monoclonal gam-mopathy.By analyzing the M band staining in different clinical groups,we found that M bands were mainly with dense and thick staining in monoclonal immunoglobulin group,the dense staining rate of MM was 90.6%,and the difference between MM and the other monoclonal gammopathy was not significant(P >0.05).In contrast,M bands were in light and narrow staining in non-mono-clonal immunoglobulin group,the rate of which was 25.8%,the difference between non-monoclonal immunoglobulin group and monoclonal immunoglobulin group was statistically significant(P <0.01).The proportion of allelic band in MM,other monoclonal gammopathy,non-monoclonal gammopathy were 39.6%,28.6% and 2.2% respectively,the differences were statistically significant (P <0.01).Conclusion The M band,accompanied by allelic band in IFE staining,is helpful in the diagnosis of monoclonal gam-mopathy,especially MM.The appearance of M protein provides early warning of monoclonal gammopathy.

In this study, the effect of hespridin, a natural flavonoid, on renal function and morphology in streptozotocin induced diabetic rats was evaluated. The result was compared with that of aminoguanidine which can inhibit the formation of advanced glycosylation end products (AGEs) and can decreased diabetic complications in experimental diabetes. The results showed that excretion of urinary protein, and the content of AGEs and LPO decreased, while the mesangial expansion and basement membrane thickening were retarded in diabetic rats treated with hespridin. These indicate that hespridin plays the same protective role as aminoguanidine in inhibiting formation of AGEs, thus preventing the development of nephropathy in STZ induced diabetic rats.

Purpose:To study the effect of combined treatment on advanced endometrium carcinoma. Methods:45 cases of stage Ⅲ endometrium carcinoma with combined treatment were retrospectively reviewed. Operation was the most used mode in the combined treatment. Depending on the pathology, metastatic site etc. 31 cases were treated in combination with chemotherapy, 11 cases with operation and radiotherapy, 3 cases with radiotherapy. All cases had hormonotherapy. The multi-drug chemotherapy was dominated by platinum agents. CFP 17 cases (54.83%),EFP 5 cases (16.12%), CAP 4 cases (12 90%), CP 3 cases(9.68%), others 2 cases. Survival analysis were done by Kaplan-Meier model of SPSS 8.0. Results:15 cases of Ⅲ stage were treated by operation and chemotherapy, 16 cases by operation chemotherapy and radiotherapy, 11 cases by operation and radiotherapy. The 2-year survival rate was 69.23%,78.97%, 70.71%. There was no difference in statistics. The 5-year survival rate was 30.29%,47.38%,14.14%. Chemotherapy in the combined treatment partly improved long-term cure P

Objective To identify a rapid and efficient fungal genomic DNA extraction method for PCR amplification.Methods Genomic DNA was extracted from Penicillum marneffei,Rhizopus microsporus,Cryptococcus neoformans and Candida albicans by heating pyrolysis,microwave,repeated freezing and thawing,lysozyme digestion,overnight snail enzymatic and Qiagen kit methods.DNA electrophoretogram was observed by gel imaging system.The concentration and purity of extracted DNA were determined with an ultramicro nucleic acid protein tester and the yields were calculated.PCR amplification and sequencing were also performed.ANOVA and SNK-q test were used for data analysis.Results There were statistical differences in concentrations and yields of the fungal DNA extracted from Penicillum marneffei (hyphal phase and yeast phase),Rhizopus microsporus,Coptococcus neoformans and Candida albicans by six methods (F=750.83,220.95,669.35,132.01,510.20 and 1658.35,287.10,963.64,1147.77,4521.22,all P ＜0.01).Of six methods,microwave method gained the highest DNA concentration and yield,followed by heating pyrolysis method,while Qiagen kit method obtained the lowest concentration and yield.All DNA extracted by 6 kinds of methods were positive in PCR amplification.Conclusion All of the six methods can be used for fungal DNA extraction which is sufficient for PCR amplification,but microwave and heating pyrolysis methods are more easy and simple to perform.

The methods for aptamer selection have been modified and developed in recent years. Selection efficiency has been increased due to the improvement in separation of bound and unbound nucleic acids; applicability of aptamers has been improved due to the development of primer-free SELEX and the utilization of short oligonucleotide library; more research requirements have been satisfied due to the functional modifications of aptamer selection methods. All the methodological advances enhance the potential value of aptamers in basic researches and clinical applications.

Aim The changes of the levels of blood sugar and plasma insulin in obese woman pa-tients with insulin resistance and the effect of insulin intravenous infusion during oper-ation were observed. Methods 10 patients of normal weight(contrast group, group A)and 20 patients of obesity women(ASA grade Ⅰ- Ⅱ) undergoing selective surgerywere investigated. The patients of obesity were randomly divided into two groups(group B and C, respectively). Groups A and B liquids without glucose, and in group Ctransfuse liquids with glucose and insulin(4g glucose add 1U insulin) were transfusedduring operation. The levels of blood sugar and plasma insulin were measured beforeand after anesthesia, during operation(30min) and after operation respectively. ResultsThere was an insulin resistance phenomenon in patients with obesity. The levels ofblood sugar and plasma insulin in patients with obesity were remarkably higher thanthose in patients of normal weight. The levels of blood sugar and plasma insulin wereextremely raised after anesthesia and during operation. The levles of blood sugar wasinhibited as insulin was infused during operation, but no hypoglycemic reaction wasfound. Conclusion There are insulin resistance phenomenon in patients with obesity.Insulin infused during operation can prevent blood sugar rise and minimize glucosemetabolism turbulence.
