Cardiovascular disease is a major cause of morbidity and mortality in the contemporary society. Cardiac gene therapy has already been investigated in clinical studies profoundly. Adenovirus vector could transfer the gene efficiently, but low organ specificity and immuno- genie properties limited its application, With adenovims vector improved in the last few years, the third adenovims vector is probably the most potential vector systems for cardiovascular disease. This review will give a broad overview of the molecular basis of the adenovims vectors, their advantages, the development of increasingly efficient gene transfer approach, and experimental and clinical studies targeting the heart, application barriers and modified strategies.

Objective To compare the safety and efficiency of endoscopic total extraperitoneal patchplasty(TEP)and modified Kugel hernioplasty for inguinal hernia.Methods The clinical data of 284 cases(312 surgeries)of preperitoneal inguinal hernia repair,including 134 cases(152 surgeries)of TEP and 150 cases (160 surgeries)of modified Kugel hernioplasty,were retrospectively evaluated from June 2009 to June 2011.Mean operative time,postoperative hospital stay,postoperative complications and recur-rence were compared between groups.Results There were no significant differences in mean operative time [(48.75 ±12.14)min vs(51.46 ±24.76)min,P=0.248],postoperative hospital stay [(5.23 ± 1.85)d vs(5.84 ±1.52),P=0.126],postoperative complications [5 cases(3.3%)vs 8 cases(5.0%), P=0.598]and recurrence [1 case(0.7%)vs 2 cases(1.3%),P=1.00]between TEP and modified Kugel hernioplasty,espectively.Conclusion TEP and modified Kugel hernioplasty are both methods for preperitoneal hernia repair and they can completely repair the defect of myopectineal orifice.They are safe and effective,which is worthy of being spread in clinical practice.

Objective To evaluate the efficacy and safety of Prostant TM and the patients’ compliance with the treatment of chronic prostatitis of different types. Methods A multi-central,randomized,double-blind,placebo-controlled clinical trial was conducted between June 2002 and December 2002.A total of 125 patients who had been diagnosed as chronic prostatitis and classified according to NIH classification system for prostatitis were divided into two groups: the trial group treated with Prostant TM anally one pill per night for 30 days and the control group given placebo in the same way.The efficacy was evaluated by the NIH chronic prostatitis symptom index (NIH-CPSI) and the WBC count in EPS after the treatment. Results Based on leukocyte and culture results,124 evaluable patients were stratified,with 48 cases of categories Ⅱ(38.7%),45 cases of Ⅲa(36.3%) and 31 cases of Ⅲb(25.0%)with chronic prostatitis.The overall NIH-CPSI scores were averagely reduced by 10.37 points in trial group and 6.65 in control group,and the symptom scores were averagely reduced by 7.34 in trial group and 4.72 in controll group,compared with pre-treatment.Significant differences of reduction were found between the two groups(P

In recent years, the study of autophagy in spinal cord injury (SCI) gradually becomes the hot spot. However, the function of autophagy in the injured spinal cord is still controversial. In order to further understand the role of autophagy after SCI, we summarized the activation of autophagy, autophagic cell death, the relationship between autophagy and apoptosis, the function of autophagy in promoting the molecular metabolism and the role of autophagy after spinal cord injury. We concluded that the role of autophagy after SCI is a double-edged sword. Upregulating the level of autophagy appropriately can promote damaged proteins metabolism and inhibit apoptosis. However, excessive activation of antophagy may induce autophagic cell dealth. So we consider that the proper regulation of autophagy will be a new target in the treatment of SCI.

Objective As important transcription factors, SOX2, TWIST and SNAIL are closely related to breast cancer me?tastasis. The aim of this study was to explore the expressions of SOX2, TWIST and SNAIL in breast cancer and the relationship between the three factors. Methods We collected 74 specimens of breast cancer and another 74 from paired normal tissue from January 2012 to January 2013. Using immunohistochemistry, we determined and compared the expression of SOX2 in the breast cancer and normal tissues. We also detected the expressions of TWIST and SNAIL proteins and analyzed the relationship of SOX2, TWIST and SNAIL ex?pressions with the clinicopathological characteristics of breast cancer as well as the correlation between the three proteins. Results The expression of SOX2 was significantly higher in the breast cancer than in the normal tissues (25.7% vs 8.1%, P=0.004) and corre?lated with the grade, lymph node metastasis, and TNM stage of breast cancer ( P<0.05) , while the expressions of TWIST and SNAIL were significantly correlated with lymph node metastasis and clinical TNM stages of the malignancy ( P<0.05) . The protein expression of TWIST was correlated positively with those of SOX2 ( Cc=0. 325, P<0.005) and SNAIL (Cc=0.308, P<0.008), and so was that of SNAIL with that of SOX2 (Cc=0.275, P<0.018). Conclusion The SOX2 protein is highly expressed in breast cancer. The expres?sions of SOX2, TWIST and SNAIL are closely related to lymph node metastasis of the malignancy and the three factors are interacted coor?dinatively in the metastasis of breast cancer.
