Objective:To explore the anti-fatigue effect of Tibet maca in mice. Methods: The mice were respectively given the powder or the alcohol extract of Tibet maca. The lactic acid concentration in blood, serum lactate dehydrogenase ( LDH) , the time of weight loading swimming and serum urea ammonia level after the exercise in the mice were detected, and the anti-fatigue effect of the powder and the alcohol extract of Tibet maca was compared. Results: After the 30-day feeding, the serum LDH activity of the mice taking the powder or alcohol extract of Tibet maca was obviously higher than that of the mice in the control group(P<0. 05), the time of weight loading swimming was significantly longer than that in the control group (P<0. 05), and the blood lactic acid concentration after the exercise was obviously lower than that in the control group (P<0. 05). Conclusion: Tibet maca can improve the time of weight loading swimming of mice, and reduce the level of serum urea ammonia after exercise and blood lactic acid concentration, sug-gesting the powder and alcohol extract of Tibet maca have obvious anti-fatigue effect.

Objective To observe the real-time and short-term anti-hypertension efficacy of ear apex bloodletting plus acupoint thread embedding. Method Eighty-three eligible hypertension patients were randomized into group A of 28 cases, group B of 29 cases and group C of 26 cases. Group A was intervened by bloodletting at ear apex, group B was by acupoint thread embedding, and group C was by bloodletting at ear apex plus acupoint thread embedding. The blood pressure was recorded 5 min before intervention, as well as 5 min, 15 min, 30 min, and 60 min following intervention, and the real-time anti-hypertension efficacy was compared. By analyzing the blood pressure before treatment and after 1-month treatment, the short-term anti-hypertension efficacy was compared. Result In group A and group C, the systolic and diastolic pressures at 15 min, 30 min, and 60 min after treatment were significantly different from that at 5 min before treatment (P<0.05). The total effective rate was 60.7% in group A, 51.7%in group B, and 80.8% in group C. The therapeutic efficacy of group C was significantly different from that of group A and B (P<0.05). The total effective rates for grade 1 and grade 2 hypertension were respectively 84.6%and 40.4%in group A, 76.9%and 31.3% in group B, and 100.0% and 64.3% in group C. In the three groups, the therapeutic efficacy for grade 1 hypertension was markedly different from that for grade 2 hypertension (P<0.05). Conclusion Bloodletting at ear apex can produce a significant anti-hypertension effect, and bloodletting at ear apex plus acupoint thread embedding is an effective method in treating hypertension.

Early diagnosis and timely treatment are two critical factors in reducing the cerebral damage and improving prognosis for ischemic stroke patients.The only proved effective way is to intravenously administer recombinant tissue plasminogen activator for thrombolytic therapy.However,the narrow time window restricts its application.One rapid and effective blood test,or auxiliary examinations such as computer tomography which may aid early diagnosis of ischemic stroke would contribute to treatment and intervention promptly,then take a pivotal role for the disease prognosis.Herein,the reported proteins and RNA markers are summarized and analysed in clinical application of acute ischemic stroke likewise.

This study was aimed to explore effect of Gui-Zhi Fu-Ling W an (GZFLW) on HIF-1α and vascular en-dothelial growth factor (VEGF) in patients with endometriosis. A total of 68 endometriosis patients in the First Peo-ple's Hospital of Xining from June 2011 to June 2013 were included. All patients received treatment of GZFLW, once a day. After one-month treatment, the treatment efficacy was analyzed. The endometrial tissues (both ectopic endometrium and eutopic endometrium) were obtained before and after treatment. The protein levels of HIF-1α and VEGF as well as the relationship of HIF-1α and VEGF were analyzed by SP immunohistochemistry. The results showed that the total treatment efficacy was 86.76%. Compared with pretreatment, the posttreatment protein levels of HIF-1α and VEGF were significantly reduced (P< 0.05). The decreasing of VEGF protein level and HIF-1α expres-sion level were positively correlated (P< 0.05). It was concluded that GZFLW had better efficacy in the treatment of endometriosis. One of the reasons may be the downregulation of protein levels of HIF-1α and VEGF in endometriosis tissues.

The tight junction of intestinal epithelium plays an important role in maintaining the function of intestinal barrier and regulating the cell differentiation. The intestinal epithelial cells interact with neighboring cells and the extracellular matrix and then affect the epithelial barrier as well as the proliferation, polarization, and apoptosis of cells. As an important cell junction, the tight junction of intestinal epithelium participates in a series of signal transduction pathways including the classic cyclic adenosine monophosphate-protein kinase A-cyclic adenosine monophosphate response element-binding, inositol trisphosphate, Ras-mitogen-activated protein kinase, phosphatidylinositol 3-kinase, and in some special pathways including zonula occludents protein 1-associated Y-box factor,cyclin related protein, phosphorylation, and methylation. Furthermore, regulations of gene and protein expression of the tight junction are also complex, while disorders of such regulations may lead to clinical diseases, such as disruption of the intestinal barrier, refractory infection, and even cancers. This article reviews the research advances in gene expressions, related signal transduction, and self-regulation in the tight junction of intestinal epithelium.
