OBJECTIVETo study the correlation between lacunar cerebral infarction and level of serum uric acid in elderly male hypertension patients.
METHODSNinety-eight elderly male hypertension patients were enrolled in this study. They all underwent cerebral magnetic resonance imaging (MRI) scan, and their clinical and laboratory data were collected. The patients were divided into the 1st group (n = 32), the 2nd group (n = 32) and the 3rd group (n = 34) according to the level of serum uric acid.
RESULTSThe numbers of lacuner infarction, serum creatinine, urea and high density lipoprotein(HDL) were significantly diferrent from the other groups. The numbers of lacuner infarction were positively related with serum uric acid and urea. Multiple variant analysis showed that serum uric acid was the independent factor of the numbers of lacuner infarction.
CONCLUSIONThe elevated level of serum uric acid may contribute to the risk factors of lacuner infarction.

Abstract: The first-line drug artemisinin is widely used against malaria. Commercially available artemisinin is extracted from plants. However, the lack of sufficient raw material, artemisinin and the cost associated with the drug's manufacture have limited the supply of ACT to most malaria sufferers in the Developing World. As such, it is important to develop a low cost, fine to environment and high-quality method to supply sufficient and reliable quantities of artemisinin in the future. The field of synthetic biology, which utilizes cell factories to manipulate microbial metabolism to enhance the production of artemisinin and its intermediates, has a particularly strong impact by providing new platforms for chemical production. After a brief introduction of the artemisinin biosynthetic pathway, the present review focuses on the introduction of artemisinin biosynthetic genes, such as the genes encoding amorpha-4, 11-diene monooxygenase, NADPH: cytochrome P450 oxidoreductase, artemisinic aldehyde delta 11(13) reductase and aldehyde dehydrogenase. The review also addresses general considerations for potential contributions of synthetic biology to artemisinin production, with an emphasis on factors influencing interest compounds production in chassis cells.

Background:The incidence of ulcerative colitis (UC)in developed countries is higher than that in developing countries,which may be related with westernized lifestyle,especially high animal protein and low complex carbohydrate diet. With the increased high fat and meat intake,synthesis and secretion of bile acid in liver is also increased,which may have an impact on the occurrence of UC. Aims:To investigate the expressions of farnesoid X receptor (FXR)and G protein-coupled bile acid receptor 5 (TGR5)in patients with UC. Methods:Thirty patients with active UC from January 2013 to June 2016 at the Affiliated Jiangning Hospital of Nanjing Medical University were enrolled,and 30 healthy subjects were served as controls. Expressions of FXR and TGR5 were determined by immunohistochemistry. Results:Compared with control group,expression of FXR was significantly decreased in UC patients (4. 63 ± 2. 07 vs. 6. 91 ± 2. 62,P =0. 00),however,no significant difference in expression of TGR5 was found between the two groups (6. 70 ± 2. 90 vs. 6. 11 ± 2. 44,P = 0. 40). Expression of FXR was significantly increased in right hemicolon colitis than in left hemicolon colitis (P < 0. 05). Conclusions:There is a significant decrease in FXR in active UC patients,indicating that FXR may have some role in the pathogenesis of UC,however,TGR5 may have no obvious effect in the pathogenesis of UC.

OBJECTIVETo investigate the incidence of depression and its etiological factors in patients with cryptorchidism 6-16 years after surgical treatment.
METHODSUsing Self-Rating Depression Scale and Correlation Factor Questionnaire, we investigated the incidence of depression symptoms among 70 patients with cryptorchidism 6-16 years after surgical treatment and another 70 healthy males as controls, and analyzed the related factors of depression symptoms.
RESULTSThe incidence rate of depression symptoms was 50% in the cryptorchidism patients postoperatively, extremely significantly higher than 4.3% in the control group (χ2 = 23.5, P <0.01). Multiple stepwise regression analysis showed that the main risk factors of depression symptoms were worries about natural fertility (F = 15.8992, P <0.01), dissatisfaction with scrotal appearance (F = 4.6003, P <0.05), and the status of being married (F = 4.1002, P <0.05).
CONCLUSIONSymptoms of depression often occur in cryptorchidism patients after operation, and the major etiological factors are infertility, dissatisfaction with scrotal appearance, and the status of being married.

Objective To analyze levofloxacin resistance in Helicobacter pylori (Hp) and the sequence difference of gyrA gene in levofloxacin resistance and sensitive Hp strains. To explore the function of gyrA gene mutation in the development of levofloxacin resistance Hp strain.Methods From July 2007 to December 2008 in Department of Gastroenterology, Jinhua People hospital of Zhejiang Province, the gastric mucosa from gastroscopy biopsy of chronic gastritis and peptic ulcer patients were cultured in Hp selective medium under microaerobic condition at 37 degrees for three to five days. The Hp strains were isolated and identified by oxidase test, catalase test,urease test and UreA gene detecting. The levofloxacin susceptibility was determined by E-test and then resistance and sensitive strains were screened. The genomic DNA of Hp strains was isolated. The gyrA gene was amplified by PCR and the sequences were analyzed. Results 38 clinical isolated Hp strains were passed the levofloxacin susceptibility E-test, among those the minimum inhibitory concentration (MIC) of 12 strains was over 1.0 μg/ml, the percentage of resistant strain was 31.58%, while the sensitive stains was 68.42%. The gyrA gene sequence result indicated 10 resistant strain with 261, 271 and 272 10 site mutation, 2 strains with C261A mutation, one strain with C261G mutation, two strains with G271A mutation, 2 strains with A272G mutation, 2 strains with C261A,G271T andA272G mutation, 1 strain with C261G and A272G mutation. However, no mutation sites were found in 26 sensitive strains. Conclusion The rate of levofloxacir-resistance in isolated clinical Hp strain was high. The drug-resistance was associated with 261,271 and 272. site mutation of gyrA gene.

The immunoregulation effect to polysaccharides from Bifidobacterium spp. was investigated on the base of functional assessment standards of health food. Effects of the EPS on immunity were investigated by promoted the proliferation of spleen lymph cells, delayed type hypersensitivity reaction, the HC50 value and macrophage function assay in mice. Data showed that the EPS could obviously increase the ratio of swallowed chicken red blood cell by macrophage and the HC50 value in mice. However, no significant effect was found on the delayed type hypersensitive induced by sheep red blood cell, for only the low dose of 100 mg/(kg?d) EPS promoted the proliferation of spleen lymph cells. Bifidobacterium spp. EPS can certain immunomodulating function.
