Objective To observe the effect of rapid reduction of physical activity on bone mass (BMC), bone mineral density (BMD)and bone metabolism in growing rats. Methods 48 male SD rats were divided into the high-intensity exercise group (T1, n=12), high tolow-intensity exercise group (T2, n=12), low-intensity exercise group (T3, n=12) and control group (Con, n=12). During the first 6 weeks,the rats in T1 and T2 group ran on treadmill with high intensity, while rats in T3 group took low-intensity treadmill exercise. 6 rats were sacrificedfrom each group at the end of 6th week. BMC, BMD of femur were measured with DEXA. Alkaline phosphatase (ALP), osteocalcin(BGP), tartrate-resistant acid phosphatase (TRACP) were detected with ELISA. The exercise intensity of T2 group was reduced rapidly to alow level as in T3 group, but remained in the other 2 groups. At the end of the second 6 weeks, the other rats were investigated again. ResultsCompared with the first measurements, ALP and BGP of the T2 group decreased significantly (P<0.05), and TRACP increased (P<0.05). There was no significant difference in BMC and BMD of femur (P>0.05). Conclusion Rapid reduction of physical activity can suppressbone formation and stimulate bone resorption of long bone among growing rats.

Objective To investigate the effect of PNS on malignant melanoma and the expression of connexin32 in melanoma. Methods The spontaneous and experimental lung metastasis models of B16 melanoma were used to investigate the inhibitory effect of PNS on tumor growth and metastasis. The expression of connexin in melanoma were detected by immunohistoehemistry. Results (1) PNS can obviously inhibit the growth of B16 melanoma. The inhibition rate of the 480mg/kg PNS group was 50. 85%. (2) PNS can obviously inhibit the lung metastasis of B16 melanoma. The number of tumor colonies in lung of the 240 mg/kg PNS group and 480 mg/kg PNS group were lower than that in the negative control group. ( 3 ) The expression of connexin32 in melanoma was detected by immunohistochemistry:PNS could up-regulate the expression of connexin32 in membrane of melanoma. Conclusion PNS can inhibit malignant melanoma growth and metastasis and could also up-regulate the expression of connexin32 in membrane of melanoma.

Objective To detect the mRNA expression of mesenchymal-epithelial transition factor (MET)gene in patients with non-small cell lung cancer (NSCLC),and to investigate the relationship and clinical significance between the mRNA expression of MET gene and clinical pathological characteristics. Methods From June 201 1 to November 201 3,48 patients with pathologically confirmed NSCLC in Chinese People′s Liberation Army General Hospital were selected.All patients included in the study were not treated before surgery.The branched DNA liquid chip technology was used to detect mRNA expression of MET gene in tumor tissues.The relationship between mRNA expression of MET gene and clinical pathological characteristics was analyzed.Results The constituent ratios of low,moderate and high mRNA expression level of MET gene were 22.9%,50.0% and 27.1 % respectively,mainly for the moderate expression.The mRNA expression of MET gene was related to the pathologic type (χ2 =7.1 83,P =0.020)and TNM stage (χ2 =24.566,P =0.01 7)of the patients;but it was not related to the gender (χ2 =0.566,P =0.754),age (χ2 =1 .857,P =0.395),smoking history (χ2 =4.959,P =0.084),degrees of differentiation (χ2 =5.749,P =0.067), lymph node metastasis (χ2 =1 .631 ,P =0.442)and distant metastasis (χ2 =4.261 ,P =0.1 1 9).Conclusion mRNA expression of MET gene is more likely to present moderate and higher level in NSCLC patients.MET gene can also be used as a biomarker for judging tumor pathological type.

Objective To explore the clinical significance and safety in hemihepatectomy for hepatoma without inflow occlusion.Methods A total of 62 patients with liver cancer were divided into 2 groups.The inflow was occluded in group A (n = 28) and not occluded in group B (n = 34) during hepatectomy.Subsequently,the influence of the two approaches on the parameters including intraoperative blood loss,postoperative hepatic function and complications incidence rate was comparatively analyzed.Results Hepatectomy was successfully performed in the two groups.There was no significant difference between the two groups in intraoperative blood loss (P ＞ 0.05).Significant difference existed between the two groups in postoperative hepatic function and complications incidence rate (P ＜ 0.05).Conclusions The hemihepatectomy for hepatoma without inflow occlusion can reduce complications incidence rate and profit the recovery of postoperative hepatic function parameters.

Eight-six heroin addicts were randomly divided into the treatment group by electroacupuncture plus Methadone and the control group by single Methadone for comparison of the therapeutic effects. Statistically there was no significant difference in the therapeutic effect (score reduction rate) between the treatment group and the control group (P＞ 0.05). In the treatment group, the dose of Methadone was half of routine dose, but the therapeutic effect was similar and side effect was less, in comparison with full dose in the control group.
