Objective To evaluate the relevant systematic reviews/meta-analyses that focused on the prevention and treatment of complications after impacted tooth extraction. Methods The systematic reviews/meta-analyses on the prevention and treatment of complications after impacted tooth extraction were searched in PubMed, The Cochrane Library, CBM, CNKI and WanFang Data from inception to September 30th, 2012, and a total of 15 professional journals and the references of included studies were also retrieved manually. Two reviewers screened the literature according to the inclusion criteria and extracted the data. Then the AMSTAR was used to evaluate the quality of the included studies, and the GRADE system was used to evaluate the quality of evidence. Results A total of twelve relevant systematic reviews/meta-analyses were included, of which five focused on the prevention and treatment of dry socket, six on the prevention of swelling, seven on the prevention and treatment of pain, six on the prevention of limitation of mouth opening, two on the prevention of infection, three on the prevention of bleeding, and one on the treatment of nerve damage after tooth extraction. Based on AMSTAR, seven studies were minor limitations and five studies were moderate limitations. Based on GRADE system, two was high quality of evidence, twelve were moderate, nine were low, and seven were very low. Conclusion Currently, the systematic reviews/meta-analyses on the prevention and treatment of complications after impacted tooth extraction can provide some references for clinical practice, which should be combined with the real condition by clinical doctors when making an evidence-based decision. However, it also suggests performing more high quality and large sample studies to prove this conclusion.
Objective To investigate the variation of total hospitalization cost for single-diagnosed disease of different types of acute appendicitis in a three-A hospital, so as to provide evidence for the reimbursement amount of social medical insurance. Methods All patients with acute appendicitis who had surgery treatment during January-April 2011 (before implementing the fee system for single-diagnosed disease) and January-April 2012 (after implementing the fee system for single-diagnosed disease) were collected in this study for analysis. According to the types of acute appendicitis, the patients were stratified into the low risk group (simple, suppurative and gangrenous) and the high risk group (perforative, abscess-formed and pregnancy-combined). The correlation between total hospitalization cost and types of acute appendicitis, as well as the changes of total hospitalization cost after implementing the fee system for single-diagnosed disease were analyzed. Results A total of 90 eligible patients were included. The disease types were positively correlated with hospital stays and total hospitalization cost. All three types in the low risk group could control the average total hospitalization cost within RMB 10 000 yuan. The results of sensitivity analysis showed that, before implementing the fee system for single-diagnosed disease, the total hospitalization cost up to RMB 6 000 yuan could be positively correlated with the above risk stratification (r=0.442, P=0.003). After implementing the fee system for single-diagnosed disease from January to April 2012, the constituent ratio of hospital stays, compared with that in the same period of 2011, had no significant difference (P=0.108) between the two groups; but the ratio of hospital stays (less than 5 days) increased from 45% to 64%, and the ratio of hospital stays (greater than or equal to 10 days) decreased from 17% to 4%, indicating a tendency of shortening hospital stays. Also, the constituent ratio of total hospitalization cost had no significant difference (P=0.114) between the two groups; but the ratio of total hospitalization cost (greater than or equal to RMB 9 000 yuan) decreased from 32% to 13%, indicating a tendency of lowering total hospitalization cost. Conclusion The low risk group of acute appendicitis, RMB 6 000 yuan should be rated as the rational reimbursement amount of social medical insurance. The total hospitalization cost for the high risk group is quite various, so the further studies are needed to investigate the feasibility of the fee system for single-diagnosed disease as well as the rating amount of total hospitalization cost. The implementation of the fee system for single-diagnosed disease is helpful to shorten hospital stays and reduce total hospitalization cost.

Objective To study the effect of HBeAg on recurrence and survival after radical resection of small (≤3 cm) hepatocellular carcinoma (HCC). Methods Two hundreds and twenty-three HCC patients undergone radical resection from 1999 to 2000 were divided into two groups according to serum HBeAg status， HBeAg positive group (n=73) and HBeAg negative group (n=150). The patients’ factors, operative factors and tumorous facors were studied retrospectively between the two groups. And risk factors of overall survival (OS) and disease-free survival (DFS) were analyzed. Results There were no significant differences in operative and tumorous factors between the two groups, but the HBeAg positive group were younger with more severe cirrhosis (P=0.004, P=0.008). The OS and DFS were significantly different between the HBeAg positive group and HBeAg negative group. The 1-, 3- and 5-year OS were 91.5%, 76.8%, 60.1% and 95.2%, 85.3%, 73.2%, respectively (P=0.053)； and the 1-, 3- and 5-year DFS were 73.3%, 53.7%, 40.3% and 86.6%, 65.5%, 54.5%, respectively (P=0.002). Multivariate analysis revealed that age ＞50 years, HBeAg positive and macronodular cirrhosis were significantly related to OS, and HBeAg positive, multiple tumor nodulars were significantly related to DFS. Positive serum HBeAg status was an independent risk factor for both OS and DFS. Conclusion Positive serum HBeAg is closely related to early recurrence and survival after radical resection of patients with small HCC.

【Abstract】Objective To study the effects of Chinese traditional medicine Sanqizonggan on bacterial translocation in rats with acute necrotizing pancreatitis (ANP).Methods The rat model of ANP was established by retrograde bilepancreatic duct injection of 5% sodium taurocholate. All rats were randomly divided into three groups: the shamoperation group(n=30), ANP group(n=30), and ANP+Chinese traditional medicine group (n=30). The serum amylase was detected at 0 h,12 h,24 h, and oneweek survival rate and pancreatic histological changes were observed in three groups, and the bacterial translocation from intestinal lumen was examined. Results The survival rate of the group treated with Chinese traditional medicine was significantly higher than that of the ANP group. The rate of bacterial translocation in the treated group significantly decreased. Conclusion The Chinese traditional medicine Sanqizonggan can promote gastrointestinal movement, protect intestinal mucosa and reduce bacterial translocation from intestinal lumen.
ObjectiveTo observe apoptosis and proliferation of choledochus wall epithelial cell and fibrocyte, to understand the effects of apoptosis and proliferation on choledochal cyst development.MethodsThirty two cases of cystic dilatation,35 cases of cylindrical dilatation，and 25 cases of cholangiectasis caused by choledocholith were collected. All specimens were offered by department of hepatobiliarypediatric surgery. The apoptosis related index (bcl2 and bax) and cell proliferation index (PCNA) were detected by the immunohistochemical technique; Apoptosis was detected by TUNEL method. ResultsThere was serious mucosal epithelial cell damage in cystic dilatation group. In cylindrical dilatation group there was a damage similar to that of the cystis dilatation group, but the damage was not serious. In control group there was little damage in the duct wall, but there was a low positive rate of apoptosis of 〔epithelium cell (2.74±1.00)% and fibroblast (2.95±0.87）%〕, and a low bcl2 and bax’s expression rate, and a high PCNA’s expression rate 〔epithelium cell (3.74±1.00)%, fibroblast (3.71±1.77)%〕. There was no obvious difference between cylindrical dilatation group and cystic dilatation group (Pgt;0.05): the PCNA’s expression rate was low 〔(0.99±0.51)% and (0.90±0.38)% respectively〕, the bax expression rate was high in remaining epithelial cell, and the positive rate of bax was apparently higher than that of bcl2 (P＜0.05), the positive rate of the apoptosis cell was high 〔(13.94±4.77)%, (7.51±3.46)%〕; the expression rate PCNA were high 〔(9.91±2.91)%,(9.70±3.18)%〕, and expression rate of bax’s was low in the fibre tissue, the positive rate of bcl2 was markedly higher than that of bax, and the positive rate of the apoptosis cell was low 〔(3.74±2.12)%,(4.46±2.41)%〕. There were no marked difference between the two groups (Pgt;0.05). The expression of bcl2 and bax had marked difference both in cylindrical dilatation group and cystic dilatation group and as compared to control group (P＜0.05). ConclusionApoptosis has certain promoting effect in the course of choledochal cyst formation.
