Background Pterygium is a common ocular surface disease and its treatment is surgical excision.But recurrence rate of pterygium is high after operation.Recently,some studies showed that the postoperatively topical administration of cyclosporine A (CsA) reduce the recurrence of pterygium,but this conclusion needs basis of evidence-based medicine.Objective This systematic review was to investigate the efficacy and safety of postoperatively topical usage of CsA in preventing the recurrence of primary pterygium.Methods A systematic literature retrieval was conducted and the relative articals were searched from MEDLINE,EMBASE,Cochrane Library,CNKI,Wanfang and VIP databases up to October 2012 according to searching strategy and correlated words.Randomized controlled trial (RCT) and prospective Cohort studies data were extracted by two researchers separately.The outcome parameters,such as the rate of recurrence,Schirmer Ⅰ test (S Ⅰ t) and complications were analyzed.The statistical analysis of the relative risk (RR) or weighted mean difference (WMD) was performed using a RevMan 5.0 software.Fixed-effect model was used for the inhomogeneity multiple studies (P≥0.1,homogeneity test I2 ＜ 50％),and random-effect model was used for the homogeneity study.Results Six prospective studies involving 366 eyes of 309 participants were identified,including 4 RCT and 2 non-RCT.The literature was published in 2008-2012 with the Jadad 5 scores in 1 paper and 2 scores in 3 papers for RCT and 6-7NOS (The Newcastle-Ottawa Scale) scores in 2 papers for Cohort studies.Meta-analysis showed that the recurrence and complication rates were significantly lower in the CsA group than those of the control group (RR =0.39,95 ％ CI:0.24-0.64,P =0.0002 and RR =0.24,95％ CI:0.13-0.44,P ＜ 0.00001) respectively.The postoperatively increased value of S Ⅰ t in the CsA group was significantly higher than that of the control group (WMD =2.47,95％CI:1.59-3.35,P ＜ 0.00001).Subgroups analyses suggested that the results were comparatively reliable.Conclusions Postoperative application of CsA can be effective for preventing recurrences and reducing complications after primary pterygium surgery.

Objective:To assess the clinical efficacy of abdominal acupuncture for subhealth insomnia.Methods:Eighty-two cases of subhealth insomnia were randomly divided into an observation group (41 cases) and a control group (41 cases).The control group was treated with conventional acupuncture.The observation group was treated with Bo's abdominal acupuncture on the basis of conventional acupuncture.Six treatments constituted one treatment course.The measuring scale of traditional Chinese medicine syndrome for subhealth state (MSSSHS) and Pittsburgh sleep quality index (PSQI) scores were compared between the two groups after two courses,to estimate the efficacy of abdominal acupuncture for subhealth insomnia.Results:One case dropped out from the observation group,while 2 cases dropped out from the control group.The MSSSHS score and PSQI score both declined after the treatment in the two groups (all P＜0.05).The MSSSHS and PSQI scores in the observation group were significantly lower than those in the control group (both P＜0.05).Conclusion:The abdominal acupuncture is effective for subhealth insomnia,and it can enhance the effect of conventional acupuncture.

Objective To investigate the changes and clinical significance of calcitonin gene related peptide (CGRP) and interleu-kin 1α(IL-1α) before and after warm acupuncture therapy in the patients with lumbar disc herniation (LDH ) .Methods Serum CGRP and IL-1αcontents were detected before and after the warm acupuncture therapy in 60 cases of lumbar disc herniation and 15 healthy control cases by ELISA method for conducting the statistical analysis .The changes of the McGill pain scores and serum CGRP and IL-1αconcentrations before and after the warm acupuncture therapy were observed .Results The McGill pain scores af-ter the warm acupuncture therapy in the LDH patients were significantly decreased ,the difference was statistically significant (P<0 .01) ,and serum CGRP and IL-1α concentrations were significantly decreased ,the difference was statistically significant (P<0 .01) .Conclusion CGRP and IL-1αcan be used as the observation index of the effects for the warm acupuncture therapy in trea-ting LDH ,which can provide the basis for the conservative treatment of LDH .

Objective:To compare the therapeutic and toxic profile of topotecan given intraperitoneally with intravenously in human ovarian cancer xenografted into athymic nude mice.Methods: Eighty female Balb-c/nu-nu mice were randomized assigned into eight groups (n=10). Xeneografts resulted from intramesentery injection of cultured human ovarian cancer cells SKOV3 in athymic mice. Onset of intraperitoneal treatment with either topotecan or cisplatin (7.5 mg/kg) was on day 7. Animals scheduled for topotecan i.p. received intraperitoneal application of topotecan (1.5 mg/kg×2, 3.0 mg/kg×2, 6.0 mg/kg×2 or 10.0 mg/kg×1). Animals scheduled for topotecan i.v. received intravenous administration of topotecan (6.0 mg/kg×2 or 10.0 mg/kg×1). Two weeks after drug application animals were killed. Tumor growth inhibition were assessed and compared with untreated mice and cisplatin intraperitoneally administered mice. Acute toxicity was determined by loss of body weight. Cell cycle division and apoptosis after drug administration was determined by flow cytometric analysis.Results: In a panel of ten tumour xenografts, intraperitoneal topotecan was significantly more effective than intravenous administration. The toxicity profile suggested a better tolerability in terms of weight loss after intraperitoneal administration than cisplatin control. Topotecan 10.0 mg/kg i.p. per day (1 day) schedule was an optimal treatment for ovarian cancer and well tolerated by mice with no signs of acute toxicity. Topotecan and cisplatin induce cells G0-G1 arrest and apparent apoptosis. No significant difference among mice treated with topotecan intraperitoneally or intravenously or cisplatin was observed in term of apoptosis and cell cycle perturbation.Conclusion:The results may have implications for the future design of clinical studies on intraperitoneal application of topotecan. It suggests that apoptosis and cell cycle perturbation play an limited role in the mechanism of topotecan administration.

Objective To investigate the relationship between clinical and pathological features in order to observe estrogen and progestin receptor(ER and PR) expressions in bilateral primary breast cancer(BPBC). Methods ER and PR expressions in 29 cases of BPBC from 1990 to 2003 and the clinical and pathological features were analyzed retrospectively. Results ER and PR positive expressions were 53 2% and 41 2% in unilateral breast cancer, but 69% and 51% in first primary cancer of BPBC, and 65% and 41 3% in second primary cancer of BPBC, respectively. Invasive lobular carcinoma(ILC) was 11 6% in unilateral breast cancer and 34 4% in first cancer of BPBC and 41.3% in second primary cancer of BPBC. Status of lymph nodes in unilateral breast cancer was similar to that in BPBC. Conclusion There is higher ER expression in BPBC than that in unilateral breast cancer. ILC is significantly related to the carcinogenesis of BPBC. The status of lymph nodes is not related to BPBC.

Objective To investigate the expression of transforming growth factor?1(TGF-?1)in human colorectal carcinoma and its value for predicting the prognosis.Methods The expression of TGF-?1 and vascular endothelial growth factor(VEGF)was measured in specimens of 52 coloreetal cancers by immunohistoehemistry.The features of clinical pathology were analyzed and the follow-up of all patients were conducted.The correlation between the expression of TGF-?1 and the survival time was studied with Log-rank test.Results Of 52 patients,no expression of TGF-?1 and VEGF was observed in 11 and 14 patients,and the expression was noticed in 41 and 38 patients,respectively.There was a signifi- cant positive correlation between expression of TGF-?1 and expression of VEGF(x~2＝0.633,P＜0.01). Furthermore,the expression of TGF-?1 was significantly correlated with Dukes staging(x~2＝19.866,P＜0.01)and metastasis of lymph nodes(x~2＝13.152,P＜0.01).The 3-year overall survival rates(OSR)in all patients was 49.1% and the 3-year OSR of patients with and without expression of TGF-?1 were 20.5% and 69.2% respectively(x~2＝11.64,P＝0.0006).Conclusion The expression of TGF-?1 could be served as an important predicator for prognosis of coloreetal carcinoma.

Heterotrimeric G proteins are classes of signal-transducing proteins that bind to guanine nucleotides and possess GTP hydrolase activity. G proteins are composed of three subunits α, β, and γ, and are considered as the "molecular switch" in the GPCR signaling pathway. The abnormal activation of G protein is strongly related to diseases such as uveal melanoma, asthma, et al., making directly targeting G protein as an promising strategy for combating diseases. In this review, the classification and physiological functions of G protein are briefly described, and the research progress of G proteins in diseases, G protein modulators are reviewed.

The purpose of this study was to evaluate the effect and safety of Jinlong capsule combined with chemotherapy or radio-therapy for non-small cell lung cancer (NSCLS) using Meta-analysis. PubMed, Embase, CNKI and Wanfang databases were all searched without language restriction, and searching time was from January 1990 to July 2015. All eligible published studies were included in this study for quality assessment and data extraction. All the data were analyzed using Revman 5.3. A total of ten studies including 736 subjects (370 in Jinlong capsule plus chemoradiotherapy and 366 in chemoradiotherapy only) were finally included in this Meta-analysis. The result of Meta analysis showed that compared with pure chemoradiotherapy group, Jinlong capsule combined with chemoradiotherapy for NSCLC could improve the patients' curative effect (OR = 1.77, 95% CI: 1.29-2.43, P < 0.05), clinical benefit rate (OR = 1.89, 95% CI: 1.22-2.91, P < 0.05), life quality improvement rate (OR = 2. 56, 95% CI: 1.61-4.05, P < 0.05), and decrease leucopenia incidence rate (OR = 0.35, 95% CI: 0. 22-0.56, P < 0.05) and gastrointestinal reaction rate (OR = 0.67, 95% CI: 0.40-1.11, P < 0.05). The pooled results showed that Jinlong capsule combined with chemoradiotherapy for NSCLC could improve the curative effect and life quality, and decrease the adverse reaction of patients.

P210(bcr/abl) fusion gene is indispensable for generation and progression of chronic myeloid leukemia (CML). Small molecule inhibitors, such as imatinib, are effective for P210(bcr/abl) gene mediated CML, but drug resistance may occur. The unique fusion junction of P210(bcr/abl) gene is an attractive target for therapeutic intervention using RNA interference (RNAi). This study was purposed to constructed the BaF3 cell line by viral vector which can stably express P210(bcr/abl) shRNA and P210(bcr/abl) mRNA at the same time, and investigate the effect of lentiviral-victor-delivered shRNA on P210(bcr/abl) gene expression. The infective rate of lentiviral vector on BaF3 cells with P210(bcr/abl) gene was assayed by fluorescent microscopy; the cell proliferation ability was determined by trypan blue exclusion; the P210(bcr/abl) mRNA and protein expressions were detected by RT-PCR and Western blot respectively. The results found that stable expression of the P210(bcr/abl) shRNA resulted in obvious inhibition of P210(bcr/abl) mRNA and protein expression and increased sensitivity of these P210(bcr/abl) gene transformed Ba/F3 cells to imatinib. The IC(50) to imatinib in these cells decreased < 50% as compared with Ba/F3-P210(bcr/abl) cells which did not express P210(bcr/abl) mRNA. The survival time of the lethal dose irradiated mice induced by intravenous injection of these Ba/F3 cells was longer than the other group induced by Ba/F3-P210(bcr/abl). It is concluded that stable expression of shRNA targeting the P210(bcr/abl) gene fusion junction may potentiate the effects of conventional therapy for CML.
