Objective To assess the effectiveness and safety of hyperthermia combined with chemotherapy(HCT)compared with chemotherapy (CT)for ovarian cancer. Methods Related literatures were searched by two independent investigators from the following electronic databases:PubMed,Cochrane Library,EMbase,VIP,WanFang Data,CNKI and CBM.Then the meta?analysis was performed by using RevMan 5.3 software. Results A total of 10 RCTs involving 546 patients were included. The results of Meta?analysis showed that the HCT group was superior to the CT group in the effective rate,tumor control rate,effective rate of CA125,ascites control rate and PD,with significant differences(P<0.05). There was no significant difference in the improvement rate of life quality and the incidences of myelosuppression,severe myelosuppression,severe nausea and vomiting,severe constipation and diarrhea,liver and renal damage(P>0.05). Conclusion Compared with CT,HCT can significantly increase short?term curative effect,ameliorate the quality of life,and it does not increase the incidence of adverse reactions. HCT is worthy of clinical applica?tion.

Background:Upon inhibition of STAT3 signaling pathway,cucurbitacin-I elicits anticancer effect in various malignancies. However,the anticancer effect and underlying mechanism of cucurbitacin-I in gastric cancer is still elusive. Aims:To explore the effect of low nanomolar cucurbitacin-I on cell proliferation,cell cycle and apoptosis in human gastric cancer cells and the underlying mechanism in vitro. Methods:Human gastric adenocarcinoma cell lines AGS and HGC-27 were treated with cucurbitacin-I at low nanomolar concentration. The anti-proliferative effect of cucurbitacin-I was detected by CCK-8 assay and colony formation assay. Flow cytometry was used to assess the cell cycle and apoptosis. Expressions of cell cycle-related proteins,as well as activation of related pathways such as caspase-3 / PARP apoptotic pathway,STAT3, GADD45α and JNK/ p38 MAPK signaling pathways were determined by Western blotting. Results:Cucurbitacin-I markedly inhibited the growth of gastric cancer cells at low nanomolar concentration by inducing G2 / M phase arrest and apoptosis via a STAT3-independent manner. Furthermore,it was revealed that the anticancer effect of cucurbitacin-I was associated with up-regulation of GADD45α,activation of JNK/ p38 MAPK signaling pathway and the subsequent apoptotic events. Conclusions:The present study provides new insights into the mechanism of anticancer effect of cucurbitacin-I, supporting cucurbitacin-I as an attractive therapeutic drug in gastric cancer.

Background The current epidemiology study had shown the prevalence of age and sex adjusted dry eye was higher in patients with diabetes than population without diabetes.Further researches demonstrated that the tear film disturbance is common after the phacoemulsification or photocoagulation in the eyes of diabetic patients.Objective The aim of this study was to characterize the clinical features of tear film instability in diabetes patients.Methods One hundred and sixty-two patients with tear-film abnormality referred to Tongren Eye Center from January 1,2010 to September 1,2010 underwent questionnaire about diabetes and other diseases,BUT,Schirmer test.Tear film instability was diagnosed as abnormality of either Schirmer test or BUT and showed as M ( Q25,Q75 ).The right eyes of 162 dry eye patients meeting with the including criteria were enrolled.The patients were assigned to two groups according to with ( 80 patients) or without ( 82 patients) diabetes mellitum.DEQ questionnaire were scored.The percentage of cases with meibomain gland abnormal score ＞ 1 was calculated.Mann-Whitney U analysis and Chisquare analysis were used to compare the difference between the two groups.Results The Schirmer test in diabetic group was 8 ( qualities:5,9 )mm and was longer than 6 ( qualities:5,7 ) mm in non-diabetic patients ( U =2452,P =0.00).The result of BUT test was 3 ( qualities:2,4 ) seconds in diabetic patients and was shorter than 4 (qualities:3,5) seconds in non-diabetic patients( U=2104,P＜0.01 ).The DEQ score of diabetic patients was 15 ( qualities:1 0,19,which was less than21 ( qualities:19,23.25 ) in non-diabetic patients.51.2 ％ ( 41/80 ) diabetic participants and 32.9％ (27/82) nondiabetic participants appeared meibography ( grade larger than 1 ) (x2 =16.07,P=0.00).The percentages of dry eyes were 51.2％ (41/80) and 93.9％ (77/82) respectively in diabetes and nondiabetes groups(x2 =37.24,P＜0.01 ).No significant correlation was found between the diabetes course and DEQ score or meibography( r =0.16,P =0.16 ; r =0.10,P =0.36 ).Conclusions Diabetes patients with tear film instability have longer Schirmer test results,shorter BUT,more severe meibomain glands damage and lower DEQ scores.The dry eye symptom is lack in the diabetic patients though appearing the tear film and meibomain glands damage.Therefore,more attention should be given to ocular surface health in diabetes patients.

Lipid metabolism disorder is an important risk factor to obesity, hyperlipidemia and type 2 diabetes as well as other chronic metabolic disease. It is also a key target in preventing metabolic syndrome, chronic disease prevention. Plant polyphenol plays an important role in maintaining or improving lipid profile in a variety of ways. including regulating cholesterol absorption, inhibiting synthesis and secretion of triglyceride, and lowering plasma low density lipoprotein oxidation, etc. The purpose of this article is to review the lipid regulation effects of plant polyphenols and its related mechanisms.

BACKGROUND:At present, it remains unclear whether delayed functional exercises after arthroscopic rotator cuff repairs could elevate the healing rate of tendon. The opportunity of functional exercises after rotator cuff repairs is stil controversial, and there is no relevant system evaluation.
OBJECTIVE:To systematical y evaluate the differences in curative effects of early and delayed functional exercises after arthroscopic rotator cuff repairs.
METHODS:We searched the Pubmed, EMBASE, Cochrane Central Register of Control ed Clinical Trials, Chinese Biomedical Literature Database, Wanfang Data, China National Knowledge Infrastructure, and Chongqing VIP Database. The key words were“arthroscopy, rotator cuff, rehabilitation”. The references of the included literatures were re-retrieved. The deadline of retrieval was August 15, 2012. The included literatures were randomized control ed trials on early and delayed functional exercises after arthroscopic rotator cuff repairs. Methodological quality evaluation, screening and heterogeneous test were conducted. REVMAN5.1 software was utilized to analyze the extracted data.
RESULTS AND CONCLUSION:We included three randomized control ed trials, including 237 patients:119 in the early movement group and 118 in the delayed movement group. During fol ow-up at 1 year after operation, no significant differences in range of motion, pain degree, American Shoulder and Elbow Surgeons Scale, Simple Should Test scores and re-tear rate of rotator cuff were detected between the two groups. Results confirmed that compared with delayed functional exercises, early functional exercises after arthroscopic rotator cuff repair did not have advantages on the improvement of joint function and range of motion, but also did not negatively affect cuff healing. Postoperative rehabilitation can be modified to ensure patient’s compliance.
