Objective To investigate the effect of UCP2 on cell proliferation, apoptosis, metastasis in cervical squamous carcinoma. Methods Plasmid?mediated downregulation of UCP2 was obtained in cervical cancer cell lines. MTT, flow cytometry and transwell chamber assay were conducted to detect the ability of proliferation, apoptosis and metastasis. Characteristics of UCP2 protein was analyzed by bioinformatics methods. Results (1)UCP2 was verified to be downregulated by qRT?PCR and Western blotting assay.(2)MTT, apoptosis assay and transwell chamber assay showed that the proliferation of SiHa cell was significantly inhibited, and the apoptosis rate was significantly increased, and metastasis was markedly deduced (P < 0.05). (3) Bioinformatic analysis showed that UCP2 was located in mitochondria with several phosphorylation sites, and UCP2 interacted with other proteins to produce biological effects. Conclusion UCP2 may play an important role in the occurrence and development of cervical cancer, and it is expected to be a new target for the early diagnosis and treatment of cervical cancer.

Objective To analyze the corneal flap thickness in laser in situ keratomileusis(LASIK) using Moria M2 microkeratome and to identify the related factors. Methods Sixty patients with LASIK were divided into two groups: M2 90 group,using the Moria M2 90 microkeratome,n=30;M2 110 group,using the Moria M2 110 microkeratome,n=30.All were performed on both eyes with the right one treated first.Subtraction pachymetry was used to measure corneal flap thickness which was analyzed statistically with the data including age,preoperative corneal diameter,curvature,corneal thickness and refraction. Results In the 30 patients of M2 90 group,the mean corneal flap thickness of right eye and left eyes were(128.03?12.03)?m(105~156 ?m) and(123.40?12.38) ?m(92~147 ?m),respectively,and the corneal flap thickness were statistically different between the right and left eyes(P

Objective To analyze the relationship between the distribution of visceral adipose and cardiovascular damage in the patients with metabolic syndrome. Methods 108 in-patients were categorized according to the diseases, they were suffering from into metabolic syndrome group (MS, 70 cases), essential hypertension group (EH, 22 cases), and type 2 diabetes mellitus group (T2DM, 16 cases). The areas of both visceral adipose (VA) and subcutaneous adipose (SA) were measured for all the three groups, and then VA/SA was calculated. The relationship of the above variables with left ventricular mass (LVM), LVM-index (LVMI) intima-medial thickness (IMT) of carotid artery, and myocardial ischemia was analysed. Results Compared with T2DM and EH groups, the area with VA was significantly larger in MS group (P

OBJECTIVE:To systematically evaluate the efficacy and safety of sodium valproate versus diazepam in the treat-ment of status epilepticus in adults,and to provide evidence-based reference for clinic treatment. METHODS:Retrieved from Med-line,EMBase,PubMed,Cochrane Library,CJFD,VIP datebase,CBM and Wanfang database,the randomized controlled trials (RCT) about sodium valproate (test group) versus diazepam (control group) in the treatment of status epilepticus in adults were collected. Meta-analysis was performed by using Rev Man 5.0 statistical software after extracting data and evaluating quality. RE-SULTS:A total of 5 RCTs were included,involving 276 patients. Results of Meta-analysis showed that recurrence rate of epilepsy in 48 h in test group was significantly lower than that of control group [OR=0.39,95%CI(0.16,0.96),P=0.04]. Compared with the control group,the effective rate controlling epilepsy within 2 h[OR=1.76,95%CI(0.88,3.52),P=0.11] and incidence of liver injury[RR=1.19,95%CI(0.38,3.70),P=0.77] were no significant differences. CONCLUSIONS:The efficacy and safety of sodi-um valproate was equivalent to diazepam in the treatment of status epilepticus in adults,however,sodium valproate was superior to diazepam in terms of controlling recurrent effect. Due to methodology limit of included studies,large-scale and high quality RCT are required for further validation of the conclusions.
