Cell polarity is a common feature of many different types of cells,and it is essential to the normal differentiation and function of cells. Partitioning defective 6( PAR6)gene encodes PAR6 protein, which is crucial to asymmetric cell division and polarized growth. PAR6 protein as a member of the PAR6 polarity complex,affects the synthetic of centrosome and protein recruitment to the centrosome. The abnormal number of centrosomal and the loss of cell polarity may eventually lead to the occurrence of tumor.

Objective To explore the relationship of plasma level of B-type natriuretic peptide (BNP) with cardiovascular risk,the severity of coronary heart disease(CHD),and the short-term prognosis in patients with type 2 diabetes. Methods 154 patients with type 2 diabetes,of them 95 cases complicated with CHD and 65 with hyper-tension were selected in this study. The CHD patients were diveded into 3 groups: AMI(n=32), UAP(n=33) and SAP(n=30). The relationship of the plasma BNP levels with cardiovascular risks, with each coronary heart disea-ses,were observed. The patients were followed up for 6 months to study the predicting role of BNP on the death in pa-tients accompanied with CHD. Results The plasma BNP level was (397.34±217.79) ng/L, which was correlated with age, CRP, hypertension and CHD (r=0.631,0.672, 0.762,0.857, P<0.05 for each);the plasma BNP levels increased with age(r=0.896,P<0.01):(57.6±12.3) ng/L in patients <50 years old,(146.2±53.4)ng/L in patients 50≤and < 59 years old, (388.4±67.5) ng/in patients 60≤and < 69 years old, and (423.8±132.6) ng/L in patients≥70 years old (P<0.01 or P<0.05). The plasma BNP levels, was higher in patients with hyper-tension than that in patients without hypertension [(314.7±125.3) ng/L vs (136.8±98.7) ng/L, P<0.01];Higher in patients with CHD than that in patients without CHD [(425.03±200.80)ng/L vs (37.64±21.57) ng/L,P<0.01)]. The short-term prognosis of patients with CHD was correlated with the levels of BNP, and BNP levels≥485 ng/L may be an independent predicting factor for cardiac death within one month. Conclusions Plas-ma levels of BNP were associated with some cardiovascular risks,which may be one of biomarkers for cardiovascular risks in patient complicated with CHD.

BACKGROUND:It is unclear whether hydrogen-rich water can be used to protect skeletal muscle injury induced by eccentric exercise, as wel as the relative mechanism. OBJECTIVE:To observe the effect of hydrogen-rich water on the mitochondrial oxidative stress and inflammation in rat skeletal muscle after eccentric exercise, and to investigate the relative signaling pathway of hydrogen-rich water. METHODS:Forty Sprague Dawley rats were randomly divided into four groups: control group, eccentric exercise group, eccentric exercise+saline group, and eccentric exercise+hydrogen-rich water group. Rats in three eccentric exercise groups were exercised on a motor-driven rodent treadmil at a speed of 16-18 m/min and a slope of-16° for 90 minutes per day. Rats in the eccentric exercise+hydrogen-rich water group were subjected to intraperitoneal injection of hydrogen-rich water (10 mL/kg) immediately after exercise; and rats in the eccentric exercise+saline group were administrated with normal saline after exercise. Al the interventions lasted for 5 days. RESULTS AND CONCLUSION:Hydrogen-rich water intervention after eccentric exercise could markedly enhance the mitochondrial Sirtuin-3 expression, improve the mitochondrial membrane potential and activity of manganese superoxide dismutase, down-regulate the mitochondrial reactive oxygen species generation and mitochondrial DNA oxidative damage, thus inhibiting inflammatory cytokines expression, such as NLRP3 and interleukin-1β. The results indicated that hydrogen-rich saline could directly scavenge reactive oxygen species. In addition, hydrogen-rich water could improve mitochondrial energy metabolism and antioxidant capacity through up-regulation of Sirtuin-3, which in turn inhibits eccentric exercise-induced mitochondrial oxidative stress and secondary inflammation in the skeletal muscle.

Objective: To evaluate the therapeutic effect of gamma knife on patients with intracranial cavernous angioma (CA). Methods: The medical records of 122 patients (134 lesions) who underwent radiosurgery were reviewed retrospectively. Results: hT e average follow-up period was 43 months. No patient died. One patient underwent CA resection. In patients with epilepsy, 83% patients showed alleviation of seizures. About 44% of the lesions shrank in size after treatment with gamma knife radiosurgery (59/134). Seven cases had hemorrhage again after radiosurgery, and the overall annual hemorrhage rate was 1.6%. Edema was found in 11.5% patients (14/122) and all patients showed improvement atf er treatment. Conclusion: Gamma knife is a safe treatment for CA, which could obviously improve the symptoms of epilepsy. Gamma knife radiosurgery is the if rst option for the treatment of cavernous sinus angiomas.

Objective:To investigate the expression of human epidermal growth factor receptor 4 (HER4) and metastasis-related protein (MMP-9) in human esophageal carcinoma tissues, and their relationship with clinicopathological features of the disease. Methods:Immunohistochemical Envision technique was applied to detect the expressions of HER4 and MMP-9 in 45 specimens of esophageal carcinoma tissues, paracancerous tissues and normal tissues. Statistical method was used to analyze the association of the positivity of HER4 with clinical pathological index and MMP-9 expression.Results:The positive rates of HER4 expression were 73.3%, 33.3%, and 2.2% in 45 specimens of esophageal carcinoma tissues, paracancerous tissues, and normal tissues, respectively. The expression of HER4 was correlated with TNM stage and lymph node metastasis (P<0.01), but not correlated with histological grade (P>0.05). The expression of MMP-9 correlated with T stage, invasion depth, TNM stage, and lymph node metastasis (P<0.05). Conclusion:The expression of HER4 is apparently different in esophageal carcinoma tissues, paracancerous tissues, and normal tissues. Its positive expression in esophageal carcinoma tissues is correlated with TNM stage and lymph node metastasis. The expression of MMP-9 in esophageal carcinoma tissues is correlated with the T stage, TNM staging, and lymph node metastasis. The positive expression of HER4 in esophageal carcinoma tissues is associated with the expressions of MMP-9.
