Objective To investigate the application of ureteral catheter in complicated gynecological laparoscopic surgery for the prevention of ureteral injury . Methods A total of 182 cases of gynecological laparoscopic surgery performed from January 2009 to November 2011 were selected as study group .Bilateral ureteral catheters were inserted under cystoscopy , and then laparoscopic surgery was performed under the instruction of the catheter .The catheter was immediately removed after the surgery .A total of 200 cases of laparoscopic surgery were selected as control group and preoperative ureteral catheterization was not applied in this group .The incidence rate of ureteral injury was compared between the two groups . Results The success rate of bilateral ureteral catheterization in the study group was 98.9%(180/182)and no ureteral injury occurred .In the control group, ureteral injury was found in 2 cases, which were converted to open surgery for ureter repair and double J stent was retained .The 2 cases recovered 2 months after the surgery.Bladder injury was found in 2 cases during the surgery , which received immediate repair assisted by surgeons from the department of urinary surgery and recovered 2 months after postoperative catheterization . No statistical difference was found in complication rate between the two groups ( P=0.125 ) . Conclusion The application of ureteral catheterization in complicated gynecological laparoscopic surgery can reduce the risk of intraoperative ureteral injury .

Objective To study the effects of γ-aminobutyric acid ( GABA) and sertraline on the CABAA(α) receptor and GABAB receptor of hippocampus neuron in rats of depression induced by acute stress. Methods The cognitive function of male SD (Sprague-Dawley) rats was screened through Y-maze. Then rats were randomly divided into five groups. Except control group,rats were injected intraperitoneally with double-distilled, GABA,sertraline or GABA + sertraline respectively. They were exposed to the forced-swimming stress test,which was to make acute stress model of depression. The space memory function in the maze was measured. Then the number of GABA-like immunoreactive neurons in hippocampus CA1 ,CA3 ,DG areas of rats were investigated with immunohistochemist. Results Compared with the model group,the immobility time in the forced-swimming test and the latency in the maze could be reduced significantly after pretreatment with GABA and sertraline (P < 0.01). The positive cell populations of CA1 ,CA3 region and DG gate region in the model group were significantly reduced compared with the control group (P<0.01). GABA could only improve the positive cell populations of GABAB receptor in CA3 region (P<0.01). In the sertraline group,the positive cell populations in hippocampus were increased obviously more than it in model group(P<0.01). The positive cell populations of hippocampus in the GABA + sertraline group in CA1 ( (82.83±8.72),(78.08±5.67)),in CA3((92.83±9.35),(76.00±3.97)),in the gate of DG( (35.00 ±1.41) ,(33.33±4.36)) increased significantly to the other groups (P< 0.05 or 0.01). Conclusion Ectogenic GABA could improve the sertraline' s effects of antagonizing acute depression effectively and the space memory function,and its mechanism may be involved in strengthening the expression of GABAA(α) receptor and GABAB receptor in hippocampus.

With acupuncture depth as a perspective, some related issues are discussed in this paper. Firstly, the possible reasons of divergence on needling depth are explained. Secondly, by literature retrieval, the advantages and disadvantages of the clinical efficacy of deep needling and shallow needling are explored, and the essential value of shallow needling is emphasized in promoting acupuncture. Thirdly, due to the placebo acupuncture that led to the controversy of the curative effect of acupuncture, it is crucial to establish a method of modern system of scientific research which should be suitable for the development of acupuncture. Finally, the "cun" in acupuncture is inappropriate to transform into millimeter, and the standardization of acupuncture should focus on the improvement of curative efficacy. From the acupuncture depth, it is clear that there are plenty of problems in acupuncture, which could not only limit the development of acupuncture, but also affect the future of acupuncture.

In order to assess whether gene transfection could be mediated by ultrasound in association with P85 and find the appropriate parameters of ultrasound irradiation, the effects of ultrasound with or without P85 on gene transfection of HepG2 cells were examined. The HepG2 cells were irradiated by ultrasound at 1 MHz, 0.4-2.0 W/cm(2) and 50% duty cycle with plasmid encoding enhanced green fluorescent protein (EGFP) as a report gene. Forty-eight h later, the expression of EGFP was detected under the fluorescence microscopy. Transfection efficacy was quantitatively assessed by flow cytometry, and cell viability was evaluated by trypan blue exclusion. The results showed that the transfection efficacy was increased with the increases in ultrasound output power and the ideal transfection efficacy was achieved in HepG2 cells irradiated by ultrasound at 0.8 W/cm(2) for 30 s. The transfection efficacy in ulstrasound+P85 group was three times higher than in single ultrasound group [(17.63+/-1.07)% vs (5.57+/-0.56)%, P<0.05]. The cell viability was about 81% and 62% in ultrasound group and ultrasound+P85 group respectively. It was concluded that ultrasound in combination with P85 could mediate the gene transfection of HepG2 cells, ideal transfection efficacy was achieved by ultrasound irradiation at 0.8 W/cm(2) for 30 s, and P85 could somewhat increase the damage to cells caused by ultrasound.

And there was a significantly negative correlationship between the principal components of TCM syndrome and patients’ quality of life.

Minimally invasive treatment of liver cancer plays a very important role in clinical practice in China, because most patients had the background of hepatitis or cirrhosis and were prone to recurrence after radical resection of the tumor. In the past four decades, much progress has been made in controlling liver cancer, which is well consistent with the trends of minimally invasive treatment. Minimally invasive therapy is also the main goals of our practice and has a great potential developing future, although a good outcome is the prerequisite. Nowadays, minimally invasive treatment for liver cancer includes percutaneous transarterial chemotherapy or embolization (TAE or TACE), percutaneous ethand injection (PEI), and ablation with radiofrequency, micromave, cryosurgery or high intensity focused ultrasound.
