Objective Evaluate the feasibility of PTCA and stents by radial artery. Methods we had operated PTCA for 25 cases by radial artery from July 2004 to April 2005. The average age is 63 years old including 40 men and 15 women. Results 67 stents were implanted in 55 patients including 30A cases, 26 B cases and 11C cases. These stents is about 8mm to 33mm in length and 2.5mm to 4.0mm in width. The successful rate is 96%(53/55), and two case was failed, because the guiding wire can not pass by chronic obstruction in LAD all. There is no case by femoral. All the procedures have no heart complications, obstruction of radial artery and vascular complications. Conclusions The way is good for PTCA by radial artery. Its advantages are mild injury, high successful rate and few complications, and the salted hospitals can use the technology successfully.

Objective To study the apoptosis of human colorectal cancer HT-29 cells induced by Aralia elata Seem leaf total saponin (ETS) and its effects on the expression of relevant proteins. Methods MTT assay was used to detect the proliferation of human colorectal cancer HT-29 cells cultivated with different concentrations (6.25, 12.5, 25, 50, 100, 200 mg/kg) of ETS. Hoechst33258 staining and laser confocal imaging were used to detect the apoptotic cells. Morphological changes were observed. The expressions of Bcl-2 and Bax were detected by immuno-histochemistry. Results ETS could induce apoptosis of HT-29 cells and apoptosis was in a dose-dependent manner in a certain range. ETS could decrease the expression of Bcl-2 and increase the expression of Bax in HT-29 cells (P<0.05, P<0.01), showing a significant dose-effect relationship. Conclusion ETS can induce the apoptosis of HT-29 cells, and the mechanism may be related to reducing the expression of Bcl-2 and increasing the expression of Bax.

Objective To explore the influence of policy support on attitude of staff toward contracted service in community health service ( CHS) centers in different areas of China. Methods A multi-stage stratified cluster sampling method was used to select participants, and questionnaire survey was conducted among 192 staff (99 from Chengdu and 93 from Xiamen) from 4 community health service centers in Chengdu and Xiamen. In addition, documents on contracted service in CHS were collected and analyzed. EpiData software was used to establish database. Double input and cross-check were implemented. SAS version 9.4 was used for data analyses. Results Differences were found in goals, financial modes and insurances coverage in contracted service in the two areas. Among the 192 participants, 80.7% considered that contracted service was worth to carry out; 90.8% supported the implementation of contracted service in local settings and 78.1% were willing to take more work load on contracted service. In contrary, only 41.6% wished their child work as a family doctor. The main reasons for the negative attitudes were that the performance-based salary system had not been well established or implemented, and there was much more work load that resulted from contracted service. Conclusions The majority of the study subjects held positive attitude toward contracted service, but there were disparities between the four study sites. Relative policy and financial support, proper human resource distribution were critical determinants of contracted service.

Hepatic encephalopathy is a common metabolic neuropsychiatric syndrome in the development of end-stage liver disease. Since the concept of intestinal-liver-brain axis was proposed, the relationship between the pathogenesis of hepatic encephalopathy and the gut microbiota has been a hot research topic. In recent years, studies have confirmed that gut microbiota is involved in and affects various pathological processes of hepatic encephalopathy. This article combines the latest research progress at home and abroad to elaborate on the research status of regulating gut microbiota and thus interfering with the pathological process of hepatic encephalopathy, hoping to provide new ideas and methods for the intervention of hepatic encephalopathy based on the regulation of gut microbiota.

OBJECTIVETo determine if double bundle hamstring autograft posterior cruciate ligament (PCL) reconstruction could bring better outcomes than single bundle.
METHODSFrom June 2007 to June 2009, there were 22 subjects, including 16 male and 6 female patients with an average (37 ± 13) years old (16-54 years old) were reconstructed with single bundle PCL reconstruction (single bundle group), 24 subjects, including 18 male and 6 female patients with an average (37 ± 10) years old (17 - 52 years old) were reconstructed with double bundle PCL reconstruction (double bundle group). There were no differences between the two groups on patients' demographics and the duration from the injury to the operation (P > 0.05). Clinical outcomes, KT2000 and tunnel placements of all the patients were measured and analyzed.
RESULTSThe two groups were retrospectively studied and compared with a (29 ± 9) months (24 - 55 months) follow-up. Operation duration of double bundle group was (92 ± 8) minutes which was significantly longer than the single bundle group (78 ± 13) minutes (t = 2.474, P < 0.05). IKDC, Lysholm and Tegner scores were all significantly improved at the last follow-up of both groups (single bundle group: t = 9.578, 13.115 and 8.165, P < 0.01; double bundle group: t = 4.390, 5.522 and 4.313, P < 0.05). Post operative KT2000 side-to-side difference of the double bundle group was significantly smaller than that of the single bundle group under maximum posterior force with the knee in 90° flexion ((1.5 ± 1.5) mm vs. (4.0 ± 2.9) mm, t = 2.538, P = 0.019). There were 66.7% of the patients of double bundle group were normal which was significantly higher than 31.8% of the single bundle group on the IKDC knee examination form (χ² = 5.576, P = 0.018).
CONCLUSIONSSingle or double bundle PCL reconstruction could restore the knee's stability and function satisfied. There are no differences between two groups in clinical scores, but double group manifestes a better anterior-posterior stability.
