Objectives :To investigate the effect of BCG - PSN on the mechanical properties of adhesion between lung cancer cells and human umbilical vein endothelial cells. Methods: Micropipette aspiration technique was used to investigate quantitatively the adhesion force (Fa) and the relative adhesion stress (S1) between high metastatic human lung giant cell carcinoma (PG) cells or low metastatic lung adenocarcinoma (PAa) cells and human umbilical vein endothelial cells (HUVEC). Further,we Invistgated the effect of bacillus of Calmette and Guerin - polysaccharide nucleic acid (BCG - PSN) on Fa and S1. Results: The adhesion force (Fa) of PG cells to HUVEC were higher than that of PAa cells under the experimental condition. With treatment using BCG - PSN, the values of the adhesion force of PAa cells to HUVEC decreased in a concentration - dependent and time - dependent manner. For PG cells, treatment with a concentration of 50?g/ml or higher resulted in a continuous decrease of the cell adhesion force. And the adhesion force to HUVEC decreased continuously with the duration of treament from 30 minutes to 48 hours, but they increased significantly again in 72 hours after treatment. The relative adhesion stress between lung cancer cells and HUVEC,S1,changed almost in the same tendency as the adhesion force,Fa. Conclusion :The adhesion forces of PG cells to HUVEC were higher than that of PAa cells under the experimental condition. The adhesion forces of both of the lung cancer cells to HUVEC can be inhibited by BCG - PSN. These results might be relative to the high metastatic potential of PG cells through blood circulation, and to the antitumor action of HCG-PSN.

Breast cancer is the most common disease in women worldwide, which not only threatened the women’s survival time, but also inlfuenced their quality of life as well. Within this challenge, it’s important to optimize the current multidisciplinary treatment stratagem for breast cancer. Radiotherapy is one of the most important treatment modality for patients with breast cancer, with the trend to shrink the irradiated volume and shorten the total fraction times in recent years. Intraoperative radiation therapy (IORT) as a fast and convenient procedure has the ability to deliver a high, single-fraction radiation dose to tumor beds with minimal exposure of surrounding tissues (lung, heart, etc.), which could be displaced or shielded right after the tumor removal during the surgical procedure. Right now, IORT has been either integrated as a boost technique in multimodal approaches using postoperative EBRT in the treatment of early breast cancer patients undergoing breast conservation surgery or used as a single dose accelerated partial breast irradiation technique for these patients. This review discussed the rationale of IORT, the beneifts and limitations of IORT, the indication and the clinical results of this procedure, including treatment related side-effects as well in order to provide the preliminary evidence based approach for early breast cancer patients.

To treat 30 patients with simple adiposis with needling of point Jiaji (Ex-B2, T3-L5), after 2 courses of treatment 12 got a marked curative effect, 15 got a curative effect, 3 got no effect, accounting for 10.0%. The total effective rate was 90.0%.

Objective To evaluate the clinical efficacy of atorvastatin combined with salvianolate in treatment of chronic obstructive pulmonary disease (COPD) complicated with pulmonary arterial hypertension (PH) , and its influence on hypoxia inducible factor-1 alpha (HIF-1α), endothelin-1 (ET-1), adrenomedullin (ADM) in serum.Methods 30 cases of COPD patients with PH were randomly divided into 2 groups, each of 15 cases.The two groups were given conventional treatment, including rest, continuous low flow oxygen, anti infection, relieving cough and phlegm, relaxing tracheal, correcting water and electrolyte balance.Control group was received Atorvastatin Calcium Tablets 20 mg orally, once daily.Observation group was received Atorvastatin Calcium Tablets 20 mg once daily, once daily;salvianolic 200 mg+0.9% sodium chloride solution 250 mL, intravenous drip, once daily.The course of treatment was 10 d.Before and after treatment, 6 min walking distance(6 MWD) and hemodynamic parameters were detected, including pulmonary artery systolic blood pressure (PASP), cardiac output (CO), right ventricular end diastolic pressure (RVEDP) , and HIF-1, ET-1 and ADM level in serum.Results After treatment, 6MWD, PASP, CO, RVEDP of the two groups were significantly improved compared with the same group before treatment.But compared with control group, observation group was improved significantly, the difference was statistically significant (P<0.05).After treatment, HIF-1 alpha, ET-1 of the two groups were significantly lower than the same group before treatment, but ADM were significantly increaser( P <0.05 ) .Compared with control group, HIF-1 alpha, ET-1 of observation group were significantly decreased, while the ADM was significantly increased, the difference was statistically significant (P<0.05).Conclusion Atorvastatin combined with salvia miltiorrhiza polyphenols can significantly reduce the pulmonary artery pressure in patients with COPD and PH, increase exercise tolerance, and its mechanism maybe related to the regulation of the expressions of HIF-1, ET-1 and ADM.

Objective To compare the clinical results of the intramedullary nails (Gamma nail and the proximal femoral nail) in treatment of intertrochanteric fractures of femur. Methods A review study was conducted on 116 intertrochanteric fractures of femur treated with the Gamma nail and 89 treated with PFN in our hospital between 2000 and 2003. Results In the Gamma nail group, the mean time for operation was 68.3(48 to 106)minutes,the mean blood loss during operation was 261(180 to 400)mL,the mean time for walking after operation was 5.0 (2.3 to 8.9)weeks and the mean time for bone union was 8.6(7.1 to 12.6)weeks. In the PFN group, the mean time for operation was 48.0(36 to 85)minutes, the mean blood loss during operation was 192(120 to 360)mL,the mean time for walking after operation was 5.3(2.5 to 8.1)weeks and the mean time for bone union was 8.8(6.9 to 12.1)weeks. There were significant differences in the mean time for operation and the mean blood loss between the 2 groups(P

Kawasaki disease is an acute self-limiting systemic vasculitis syndrome and usually occurs in children.The small and medium arteries of the whole body are mainly invaded, and marked with coronary arteries.Coronary artery dilation and aneurysm formation mainly occur in the early period.Thrombi, intimal hyperplasia, and calcification could be formed during the later period.Consequently, sometimes, it develops intochronicischemic cardiopathy or myocardial infarction.In that, Kawasaki disease has become the leading cause of acquired heart disease for children in developed countries.Presently, the treatment of coronary artery lesions caused by Kawasaki disease includes drug therapy, and interventional and surgical treatment.However, medications usually fail to solve severe coronary conditions, and only interventional and surgical treatment can we choose.Therefore, the development and indications of interventional and surgical treatment of coronary artery lesions caused by Kawasaki disease were reviewed in this article.

Purpose To investigate the expression of RNF2 in breast disease tissues and cell lines,and to analyze the association between expression of RNF2 and clinicopathological characteristics in breast carcinoma.Methods Expression of RNF2 protein and mRNA levels was detected using immunohistochemistry of EnVision two-step and qRT-PCR in breast carcinoma and benign breast disease as well as in cell lines.Results RNF2 expression was sigmificantly higher in breast carcinoma tissue specimens compared with benign breast disease specimens (P ＜0.05).Besides,the expression of RNF2 protein was significantly associated to tumor size,lymph node status and TNM stage (P ＜ 0.05 for both),but was not related to age,histological grade,the expression of ER,PR and HER-2 (P ＞ 0.05 for both).Higher expression of RNF2 mRNA was detected in breast carcinoma cell lines compared with breast epithelial cell lines (P ＜ 0.05).Conclusion RNF2 is overexpressed in breast carcinoma and can be a potential therapeutic target for breast carcinoma.
