Metformin has become the first-line drug for the treatment of type 2 diabetes, which is stably efficacious, safe, and cheap. Previous studies have shown that the application of metformin can decrease the rate of tumor incidence, recurrence, and metasta-sis. It can also improve the prognosis of cancer patients and their lifetime after long-term use. Considering its multiple advantages, met-formin has become an emerging choice for the treatment and prevention of cancer. Therefore, the mechanisms through which metfor-min inhibits tumor metastasis in cancer therapy are worth investigating.

Objective To explore the effect of new labor standards on the intrapartum interventions and delivery outcome for gestational diabetes mellitus primiparas in labor by comparing with materal who were in accordance with the Friedman standards. Methods From May to November 2015, 319 singleton and full-term gestational diabetes mellitus primiparas whose labor treatment was according to new labor standards were selected as observation group. From November 2014 to April 2015, materal in accordance with the Friedman standards were selected as control group, a total of 292 cases, and then progress of labor, the usage of oxytocin, delivery way, postpartum hemorrhage, neonatal hypoglycemia and asphyxia were all observed. Results There was no significant difference between two groups in the rate of postpartum hemorrhage, neonatal hypoglycemia, neonatal asphyxia and neonatal mobidities (P>0.05). The total labor stage, the first labor stage and the second labor stage was (10.73 ± 4.00), (9.97 ± 3.89), (0.60 ± 0.38) h in observation group and (8.86 ± 3.09), (8.19 ± 3.00), (0.53 ± 0.31) h in control group, there was significant difference between two groups (t=18.184, 17.799, 6.798, all P<0.01). The incidence of artificial rupture, the usage of oxytocin, caesarean section was 22.57%(72/319), 16.93%(54/319), 5.64%(198/319) in observation group, and 28.77%(84/292), 22.95%(67/292), 9.59%(28/292) in control group, and there was significant difference between two groups(χ2=3.079, 3.476, 3.410, all P<0.05). The incidence of episiotomy was only 29.47% (94/319) in observation group, significantly less than that in control group, which was 51.37% (150/292), there was significant difference (χ2=30.490, P<0.01). Conclusions For gestational diabetes mellitus primipara, the new labor standards effectively reduce intrapartum interventions, the rate of cesarean sections and episiotomy, and more, less influence on maternal and newborn, which is helpful to promote the maternal reproductive health and natural delivery.

Objective To study the relationship between the expression of matrix metalloproteinase-9 in rat brain and pathogenesis of epilepsy.Methods The expression of matrix metalloproteinase-9 in hippocampus was observed by immunochemistry in normal and epilepsy rat.Meanwile,the effects of dexamethasone before epilepsy on the expression of MMP-9 in hippocampus was evaluated.Results The expression of MMP-9 in hippocampus were fewer in normal rat brain.The expression of MMP-9 had increased in hippocampus after epilepsy 24h.It had increased obviously in dentate gyrus(DG)after epilepsy 72h than 24h(P0.05).Dexamethasone suppressed the expression of MMP-9 in hippocampus.Conclusion The expression of MMP-9 in rat brain participates in immunopathogenesis of epilepsy by affecting brain immunoreaction,leading to the change of neuronal response and synapse remodeling in hippocampus,regulating brain nervous cell excitability.Dexamethasone plays a prominent suppressant role in the processes.

Objective To assess the effect of fructose sodium diphosphate and alpha-lipoic acid on diabetic peripheral neuropathy. Methods Sixty-six patients with diabetic peripheral neuropathy were randomly divided into two groups, additional to the regular treatment to control blood glucose, 34 patients in the treatment grouptreated with fructse sodium diphosphate 10 g and alpha-lipoic acid 0.45 g daily through intravenous drip for two weeks (3 patients dropped out due to un-tolerance), 32 patients in the control group treated with alpha-lipoic acid 0.45 g dai-ly through intravenous drip for two weeks. All patients were examined on the improvement of symptoms, motor and sensory nerve conduction velocity of the median nerve and nervus peroneus communis before and after the treatment. Results After treatment for two weeks, the overall effect rate in the treatment group was 93.55 % (28/31), which was significantly higher than that in the control group(68.75%,22/32) (P < 0.05). In the treatment group, the motor nerve conduction velocity for the median nerve and nervus peroneus communis was 47.7 (SD:3.8) m/s and 41.6 (SD: 3.3) m/s after treatment, which was significantly higher than that before treatment (42.5 [SD:2.5] and 36.0[SD:2.8] m/s,respectively) (P <0.05). In the control group, the motor nerve conduction velocity for the median nerve and nervus peroneus communis was 43.4 (SD: 2.0) m/s and 39.6 (SD: 3.3) m/s after treat-ment, which was significantly higher than that before treatment (41.9 [SD16.0] and 36.2 [SD: 1.9] m/s, respec-tively) (P < 0.05). In the treatment group,the sensory nerve conduction velocity for the median nerve and nervus peroneus communis was 40.3 (SD: 1.8) m/s and 34.1 (SD: 2.3) m/s after treatment, which was significantly higher than that before treatment (35.2 [SD:2.3] and 28.8 [SD:2.5] m/s,rospectively) (P <0.05). In the control group,the sensory nerve conduction velocity for the median nerve and nervus peroneus communis was 37.7 (SD:1.7) m/s and 30.8 (SD:2.6) m/s after treatment,which was significantly higher than that before treatment (34.8 [SD :3.1] and 27.8 [SD :2.4] m/s, respectively) (P < 0.05). Furthermore, the improvements in the treat-ment group was significantly higher than those of the control group (P < 0.01). Conclusions Fructse sodium si-phosphate combined with alpha-lipoic acid is more effective to treat diabetic peripheral neuropathy than alpha-lipoic acid only.

Histone deacetylase inhibitors (HDACI) can improve the acetylation status of histone N-terminal, which will exert the effect on treatment. The N-terminal of histone modifications belongs to the category of epigenetics. Epigenetics mainly refers to the study of the heritable variation without change in DNA sequence. HDACI had been paid much attention as a new non-cytotoxic an-ti-cancer targeted drug. Thus, the application of this drug in clinical research is widespread. After the U.S. Food and Drug Administra-tion approved two HDACIs for the treatment of cutaneous T-cell lymphoma, the clinical applications of HDACI in other subtypes of T-cell lymphoma have obtained increasing attention. Studies on the mechanism of HDACI provide the theoretical basis for the applica-tion of HDACIs in other subtypes of T-cell lymphoma. In this article, we reviewed the mechanism and clinical trials of HDACIs on the treatment of T-cell lymphoma.

HCV NS5B, acting as a RNA dependent replication enzyme,has emerged as an attractive protein used as a target for screenig of drugs against HCV NS5B, and plays an important role in HCV replication. In the report the gene expression of NS5B in E.coli was investigated. PCR was performed to gain the gene of HCV NS5B from plasmid pBRTM/HCV 1 which contains whole sequence of HCV, and the truncated NS5B gene containing no hydrophobic domain was cloned into pGEM Teasy vector. The gene of the truncated NS5B was cut from pGEM Teasy vector and cloned into E.coli expression plasmid pET 21b, then pET 21b NS5B was transfected into E.coli cells. The protein E.coli lysates were purified and analyzed by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS PAGE) and Western blotting assay. The RdRp activity of NS5B was examined by scintillation proximity assay (SPA). The truncated NS5B gene was successfully cloned into pET 21b. The results of SDS PAGE and Western blotting assay showed: ①the molecular weight of the expressed product was about 68 000 D, ②The truncated NS5B protein was existed in media of E.coli cells, ③The activity of NS5BDCT21 His from HCV 1b amounted to 6 900 cpm (total incorporation of approximately). These findings suggest that soluble NS5B can be successfully expressed in E.coli and could secret into media.
