Objective To observe the regulation effect of transforming growth factor alpha(TGFα) on expression of glutamate transporter(GLAST)and ingestion activity of retinal M(u)ller cells in mice.Methods To take the retinal tissue of Kunming mouse at postnatal 7～10 day.and then cultured M(u)ller cells according to literature.The 3～4 generation cultured cells of the same primary cell were divided into two groups at random:①TGFα group:maintained in different concentrations of TGFα as 50,75,125 and 150 ng/ml,3 holes in each concentration;②Control group:cultured by Eagle culture medium which improved from Dulbeccon and contained 20%fetal calf serum.The influence of different concentrations TGFα on GLAST activity in M(u)ller cells were observed by L-3H-glutamate uptake detection;the expression of GLAST mRNA in M(u)ller cells was determined by RT-PCR;the expression of GLAST protein was detected with immunocytochemical staining.Results With the increase of TGFα concentration.both L-3H-glutamate uptake and GLAST mRNA expression were increased.The L-3H-glutamate accumulation had got to the maximum uptake at concentration of 125 ng/ml,which was 266% of that in control group,meanwhile,the expressions of GLAST mRNA also got to the maximum as 4 times of control group.Immunocytochemical staining indicated that the effect of 125ng/ml TGFα on expression of GLAST protein was higher than that in the control group,the differences between two groups were statistically significant(P＜0.05).Conclusion TGF-α can increase GLAST activity through up-regulating the expression of GLAST mRNA and protein.

Objective To study clinical effect of laparoscopy combined with gestrinone in treatment of ovarian endometriosis cyst and the prognoisi of patients. Methods A randomized, controlled, prospective study was used in this study, 78 patients with ovarian endometriosis cyst were selected in Sichuan province panzhihua city miyi people's hospital from august 2012 to august 2014, and were randomly divided into observation group and control group, 39 patients in each group. Patients in the observation group were treated with laparoscopy combined with gestrinone (2.5 mg/time, two times per week, for 6 months) intervention; patients in the control group were treated with laparoscopic intervention. After six months, the postoperative serum FSH (Follicle Stmi Ulating Hormone, FSH), Estradiol (E2) and Estradiol levels, ovarian biggest plane average diameter (D), the level of MMP-9 and TIMP -1 level, pregnancy outcome of two groups were compared and the outcome and the recurrence rate 18 months after treatment were followed up. Results Six months after treatment, the E2 and FSH levels in the observation group were better than control group, with statistically significant difference (P<0.01);the postoperative serum levels of MMP-9 and TIMP-1 in Observation group were better than control group, with statistically significant difference (P<0.01);there were 20 patients of D≤2 cm, 19 patients of D>2 cm, the postoperative ovarian shrink rate was 51.28% in the observation group; there were 5 patients of D≤2 cm, 34 patients of D>2 cm ovarian shrink ratio was 12.82% in the control group, the ovarian shrink ratio of observation group was obviously higher than control group, with statistically significant difference (P<0.01) . Follow-up for 18 months, the recurrence rate was 5.13%in the observation group, which was significantly lower than thatin the control group (25.64%), with statistically significant difference (P<0.05);the pregnancy rate was 66.66%and 30.77%in the Observation group and control group, respectively, the difference had statistical significance (P<0.01) . Conclusion Laparoscopic surgery combined with gestrinone can protect ovarian function of patients with ovarian endometriosis cyst, improve pregnancy outcomes, and reduce recurrence rate, and has good clinical value.

Objective To investigate the effect of ovariectomy and estrogen on secretion function and number of pancreatic islet beta cell in low-dose streptozotocin-induced diabetic rats. Methods Thirty female SD rats were randomly divided into five groups: normal control(NC) group, streptozotocin(STZ) group, ovariectomized(OVX) group, OVX + STZ(OS) group and OVX+STZ+estradiol(OSE) group. OVX, OS and OSE groups underwent ovariectomy, while NC and STZ groups underwent just sham operation. After surgery, OSE group was treated subcutaneously with estradiol 0.2 mg/kg twice weekly. At the end of 3 weeks, STZ, OS and OSE groups were induced by a single intraperitoneal injection of 40 mg/kg STZ. Then eight days later, plasma glucose and insulin levels were tested. The insulin protein, the average beta cell area and the relative beta cell mass were tested by streptavidin peroxidase conjugation method (SP). The quantification of beta cell apoptosis was performed by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL). The expressions of proliferating cell nuclear antigen(PCNA) protein, Bax and Bcl-2 were tested. Results With the administration of low-dose STZ, the plasma glucose was significantly higher and the insulin secretion curve after glucose loading, △I30/△G30 and modified beta cell function index(MBCI) were lower in OVX group than in other groups(all P<0.05). At the same time, the insulin protein, the relative beta cell mass and the beta cell area were dramatically decreased(all P<0.05). The beta cell apoptotic index was increased (t = 2.957, P< 0.05), the expression ratio of Bcl-2/Bax was decreased (0.41±0.03 vs. 0.76±0.05, P<0.05). Estrogen replacement therapy could obviously inhibit these changes. Compared with OS group, glucose disturbances and insulin secretion were improved dramatically in OSE group(all P<0.05); the insulin content, the relative beta cell mass and the average beta cell area were all enhanced (all P<0.05); the beta cell apoptotic rate was decreased(t =2.482, P<0.05), and the expression tatio of Bcl-2/Bax was increased (0.71±0.05 vs. 0.41±0.03, P<0.05). Conclusions The ovx rats are significantly more susceptible to low-dose STZ toxicity than in control rats. Under the effect of STZ, the ability of insulin secretion of beta cell is obviously decreased, while apoptosis is increased, which induces a higher glucose level and a lower insulin secretion. Administration of estrogen may protect OVX rats from the metabolic disturbances.

Abstract?AIM: To analyze the effects of femtosecond laser assisted cataract surgery ( FLACS ) in the treatment of cataract and its effect on prognosis.?METHODS:Forty-two cases (42 eyes) of patients with cataract who were treated in the Department of Ophthalmology in our hospital between January 2012 and December 2014 were selected as the study objects. According to the order of treatment, they were divided into control group and observation group, 21 cases in each. The control group was treated with traditional phacoemulsification cataract surgery ( PCS ) . On the basis, the observation group was treated with femtosecond laser. The effective phacoemulsification time (EPT), cumulative dissipated energy (CDE), fluid flow and monitored pressure of the two groups were recorded.The rate of corneal endothelial loss and the situation of Tyndall phenomenon were statistically analyzed.The two groups were followed up for 1a.The long-term visual acuity recovery was observed.The best corrected visual acuity ( BCVA ) was recorded, and the long-term complications were statistically analyzed.?RESULTS: 1 ) The total response rate in observation group was 95% while in control group was 90% ( P>0.05);2) the surgery time of the observation group was longer than that of the control group ( P<0.05) but EPT was shorter than that of the control group.CDM and liquid flow were less than those of the control group ( P<0.05 ); 3 ) at 1d after surgery, there was no significant difference in intraocular pressure between the two groups (P>0.05); the rates of Tyndall phenomenon and corneal endothelial loss in the observation group were lower than those in the control group ( P<0.05);4) BCVA of the two groups at different time after surgery were significantly higher than that before surgery (P<0.05). However, at 1d, 3mo, 6mo and 1a after surgery, BCVA of the observation group was better than that of the control group ( P <0.05 ); 5 ) the incidence of complications in the observation group after surgery (14%) was lower than that in the control group (43%) (P<0.05).?CONCLUSION: The surgical effects of FLACS in the treatment of cataract are good.After surgery, the visual acuity of patients is improved significantly and the incidence of postoperative complications is low. However, the surgery time is long and cost is high, so it is difficult to popularize.

Objective To observe the level of homocysteine(Hcy),high sensitive C-reactive protein(hs-CRP)and D-Dimer(D-D) in peripheral blood of patients with coronary heart disease,and to explore their values in clinical diagnosis of the coronary heart dis-ease(CHD).Methods Total of 95 patients with coronary heart disease were selected including 27 patients with AMI,42 patients with UAP and 26 patients with SAP.50 health examination volunteers were served as contro1.The levels of Hcy,hs-CRP and D-D were measured.Results The levels of Hcy in AMI group,UAP group and SAP group were significantly higher than those in con-trol group(P <0.05).The levels of hs-CRP and D-D in AMI group and UAP group were significant higher than control group and SAP group(P <0.05).The level of hs-CRP in SAP group was much higher than the control group(P <0.05),whereas the level of D-D in SAP group was not significantly different from control group(P <0.05).Conclusion The changes of serum levels of Hcy, hs-CRP and D-D are related with the occurrence and development of CHD.The joint detection of Hcy,hs-CRP and D-D can better reflect the severe degree of CHD,and could be helpful for early diagnosis,therapy and prognosis of CHD.
