Acetabulum fracture, the inner fracture of the joint, has be en divided into 10 kinds. Because acetabulum is an irregular body, no single ope ration approach can solve all kinds of acetabular fracture. Appropriate selectio n of the operative approach according to the type of fracture is very important. Kocher-Langenbeck approach, extended-iliofemoral approach and ilioinguinal ap proach are often used in clinic now. Because of its complicated procedures and m any complications resulting from the approach, the application of extended-ilio femoral approach is decreasing. Because of its predominant advantage and improve ment of the operation techniques, the use of ilioinguinal approach is obviously increasing in proportion. Since the united approach can reveal clearly so that i t facilitates reduction and internal fixation, it is recommended by the surgeons at home and abroad.

OBJECTIVE:To discuss the effect of early usage with Wulingjun powder on the behavior of rats with post-traumat-ic stress disorder(PTSD)and the level of interleukin-1β(IL-1β)and IL-6 in their hippocampi. METHODS:50 SD rats were ran-domized into control group(normal saline),model group(normal saline),positive control group(paroxetine,10 mg/kg)and the groups of low and high-dose(0.4,0.8 g/kg)Wulingjun powder. The rats in all groups except for control group,were exposed to single prolonged stress for the establishment of PTSD models. Corresponding drugs were given ig immediately after such establish-ment,qd,for 7 consecutive days. An open field test(the times of the rats’entering the central area and the percentage of the time the rats spent in exploring the central area within 10 min were recorded)was conducted 7 days after giving drugs;and an elevated plus-maze test(the times of the rats’in opening arms and the percentage of the time the rats spent in opening arms within 5 min were recorded)was carried out 8 days thereafter,to observe the behavior of the rats. Then the rats were sacrificed to determine the level of IL-1β and IL-6 in their hippocampi by ELISA. RESULTS:Compared to the normal group,the behavioral index of the rats in model group was significantly lower,and the level of IL-1β and IL-6 in their hippocampi was significantly higher(P<0.05 or P<0.01). Compared to model group,the behavioral index of the rats in positive control group and the group of high-dose Wuling-jun powder was significantly higher,and the level of IL-1β and IL-6 in their hippocampi was significantly lower (P<0.05),but no statistically significant difference was shown in all indexes in the group of low-dose Wulingjun powder (P>0.05). CONCLU-SIONS:High-dose Wulingjun power can improve the anxiety-like behavior of the rats with PTSD,which may be related to the re-duction in the level of IL-1βand IL-6 in the hippocampus.

Objective To carry out a meta-analysis on the published data in order to evaluate the clinical efficacy of prophylactic antibiotics in severe acute pancreatitis (SAP). Methods We searched the MEDLINE, EMBASE, Cochrane data base for systematic reviews and China biological medicine for randomized controlled trials on the efficacy of prophylactic antibiotics in patients with SAP from 1975 to May 2010. Eight studies met the inclusion criteria. Two authors independently extracted the data from these studies. The data were analyzed using the RevMan 4. 2. 10 software. Result In patients with SAP, prophylactic antibiotics did not reduce pancreatic infection (OR = 0. 67,95% CI:0. 43~1. 02,P = 0. 06), surgical intervention (OR = 0. 90,95% CI: 0. 60~ 1. 36 ,P = 0. 63) and mortality rate (OR = 0. 69,95% CI: 0. 41~1. 15,P=0. 16). Conclusion Antibiotic prophylaxis of SAP did not reduce mortality. It did not protect against pancreatic infection and the frequency of surgical intervention.

Chinese Pharmaceutical Journal 2013;48(24):2117-2122
OBJECTIVE: To investigate the therapeutic efficacy of treatment of Bacillus licheniformis (BL) on ulcerative colitis(UC) in BALB/c mice. METHODS: The therapeutic effect of different treatment was evaluated in seven acute UC mice groups and one control group, including the normal group, the model group, the solvent group, the sulfasalazine (SASP) treated group, the high dose BL treated group, the low dose BL treated group, the high dose BL with SASP treated group and the low dose BL with SASP treated group. The disease activity index (DAI) score of mice were recorded every other day since the experiment started. On the 15th day, all the mice were killed, then gross injury score in colonic mucosa and histopathological changes were measured. The expression levels of NF-κB and Bcl-2 in mouse colonic mucosa was also determined by immunohistochemistry method. RESULTS: The DAI score, the colonic gross injury score, the histopathological changes and the expression level of NF-κB and Bcl-2 of mice colonic mucosa in drug treated groups were decreased significantly when comparing with the drug untreated groups. Moreover, these results were even better in two drugs combined treated groups than in single drug treated groups (P<0.05). CONCLUSION: BL has the efficacy of remission DSS-induced acute ulcerative colitis in mice, and there is more effective when it is administered with SASP. The results indicat that the therapeutic effort is via inhibiting the expression of NF-κB and Bcl-2 in colonic mucosa.

Ischemic heart disease (IHD), which has been considered to be exclusively caused by stenosis or occlusion of coronary artery, is a significant cause of morbidity and mortality worldwide. Mitochondrial dysfunction is the main pathological basis of ischemic heart disease and reperfusion injury, and moderate mitochondrial autophagy can selectively remove damage proteins and organelles to maintain intracellular homeostasis, so mitochondrial autophagy is important for maintaining the homeostasis of cardiomyocytes. Natural drugs from plants are widely used in ischemic heart disease. In recent years, more and more natural drugs have been proven to alleviate myocardial cell damage after ischemia/reperfusion through mitochondrial autophagy. This paper reviews the research progress of natural drugs from plants medicines regulating mitochondrial autophagy in the treatment of ischemia heart disease.
