Bacillus subtilis is a generally recognized as safe (GRAS) strain that has been widely used in industries including fodder, food, and biological control. In addition, B. subtilis expression system also plays a significant role in the production of industrial enzymes. However, its application is limited by its low sporulation frequency and transformation efficiency. Immense studies have been done on interpreting the molecular mechanisms of sporulation and competence development, whereas only few of them were focused on improving sporulation frequency and transformation efficiency of B. subtilis by genetic modification. The main challenge is that sporulation and competence development, as the two major developmental events in the stationary phase of B. subtilis, are regulated by the complicated intracellular genetic regulatory systems. In addition, mutual regulatory mechanisms also exist in these two developmental events. With the development of genetic and metabolic engineering, constructing genetic regulatory networks is currently one of the most attractive research fields, together with the genetic information of cell growth, metabolism, and development, to guide the industrial application. In this review, the mechanisms of sporulation and competence development of B. subtilis, their interactions, and the genetic regulation of cell growth were interpreted. In addition, the roles of these regulatory networks in guiding basic and applied research of B. subtilis and its related species were discussed.

AIM: To study the influence of PD098059 on the rat platelet aggregation rate and the phosphorylation of ERK1/2 induced by the different agonists, and to observe the effects of phosphorylation of ERK1/2 on the platelet aggregation. METHODS: The maximal aggregation rate (MAR) was measured by nephelometry. The inhibitory rate of PD098059 and the appearing time of MAR were also observed. ERK1/2 phosphorylation was detected by Western blot. RESULTS: The phosphorylation of ERK1/2 was detected during aggregation induced by thrombin and ADP. PD098059 inhibited the MAR and phosphorylation of ERK1/2. Effects of PD098059 were different on the aggregation induced by thrombin and ADP. CONCLUSIONS: The phosphorylation of ERK1/2 is one of the cellular signal transduction mechanisms of platelets aggregation. Phosphorylation of ERK1/2 plays different roles during the platelet aggregation induced by thrombin and ADP. [

Objective: To analyze the expression of CMTM1-v17 in normal prostate tissue and prostate carcinoma originated cell lines, and study its impact on the transactivation of androgen receptor and the possible mechanism. Methods: The expression of CMTM1-v17 in normal prostate tissue was analyzed with immunohistochemistry method. In immounocytochemistry was used to analyze the expression of CMTM1-v17 in prostate carcinoma originated cell lines. Luciferase assay was used to study the impact of CMTM1-v17 on the transactivation of AR and its mechanism. Results: The results of immunohistochemistry showed that CMTM1-v17 was highly expressed in prostate. In prostate cancer originated cell lines, CMTM1-v17 could also be detected in prostate cancer originated cell lines PC3, Du145 and LNCaP. And the results of luciferase implied that the relative luciferase activity of the PC3 cells transfected with 1 ?g and 2 ?g pCDI-CMTM1-v17 plasmids separately were 70.8 and 34.7, compared with the control set as 100. When trichostatin A, the inhibitor for histone deacetylase, was used, the repression of androgen receptor could be recovered with trichostatin A treatment,for the relative luciferase activity of the PC3 cells transfected with 1 ?g and 2 ?g pCDI-CMTM1-v17 plasmids and treated with 100 nmol/L trichostatin A rebound to 90.9 and 86.4. Conclusion: CMTM1-v17 is highly expressed in both normal prostate and prostate carcinoma originated cell lines. It may recruit histone deacetylas to inhibit the function of androgen receptor.

Objective To evaluate the symptom improvement of anxiolytics and antidepressant to hemifacial spasm(HFS)patients with anxiety and depression. Methods A total of 60 HFS patients with anxiety and depression were enrolled for the study and divided into experimental group and control group. Experimental group were treated with escitalopram and BTX-A ,and control group only received BTX-A. SAS and SDS were used to test all the patients before and after treatment. Results Both experimental group and control group were significantly improved after BTX-A therapy. There was no different between two groups at 1 week and 1 month,respectively. At 2 weeks and 3 months,more obvious improvement was seen in experimental group. The SAS and the SDS standard average scores of experimental group were significantly decreased compared with the control group. There was statistical significance in control group after 1 month and 3 months treatment(P<0.05),and in experimental group,the differences appeared after 2-week treatment(P<0.05). Additionally,after 1 month treatment,there were statistical differences between the two groups(P<0.05),and experimental group shown a longer effective period compared with control group. Conclusion Anxiety and depression state serves as a complication of HFS ,which is positively correlated with HFS. HFS patients with anxiety and depression benefit better from escital-opram and BTX-A combination therapy than BTX-A alone.

Objective:To investigate the antioxidant activity of the total flavonoids of Cinnamomum septentrionale Hand.-Mzt. Methods:A ferricyanide reduction method was used to study the reduction ability.

Hyperuricemia is a risk factor for various diseases, but knowledge on acute hyperuricemia is still not sufficient. The present study was aimed to investigate the effect of acute hyperuricemia on red blood cells from hemorheological point of view, and to provide the reference for clinical treatment. The rats were gavaged with 500 mg/kg hypoxanthine and intraperitoneally injected with 100 mg/kg oxonate to induce the model of acute hyperuricemia. The same volume of blood samples were drawn within time period of 0, 1, 2, 3 and 6 h, respectively, from the inner canthus of rats to measure the serum uric acid, hemorheological parameters and the malondialdehyde level. It was found that in each period of 1, 2 and 3 h, the rats had significantly higher levels of uric acid. The integrated deformation index and relax index were increased. The hemolysis rate was significantly reduced. The plasma malondialdehyde level was obviously decreased at the end of 2 h. The results suggested that short-term elevated uric acid could improve the hemorheological parameters and the lipid oxidative level in red blood cells.
