Objective To assess the effect of opiod pretreatment on etomidate induced myoclonus. Methods The pertinent literatures were searched by two independent investigators from the following electronic databases:PubMed,Cochrane Library,EMbase,VIP,WanFang Data,and CHKD. Then the meta?analysis was performed by using RevMan 5.2 and STATA 12.0 software. Results A total of 24 RCTs involving 2 396 pa?tients were included for the study. Pretreatment ofμorκ?receptor agonists reduced myoclonus with RR=0.19(95%CI 0.14 to 0.27)and RR=0.22 (95%CI 0.12 to 0.40),respectively. Conclusion Pretreatment of opiods can reduce the incidence of etomidate induced myoclonus.

Objective To evaluate the techniques and effects of post-operational surgery of colorectal cancer for metastatic tumor on caudate lobe of liver. Methods For the patients admitted from Jan. 1999 to Jan. 2007 to the Navy General Hospital of PLA and undergone metastasectomy on caudate lobe of liver after colorectal cancer operation, the operative procedure and effects were studied retrospectively. Results A total of 18 cases of metastasectomy on caudate lobe of liver were successfully performed. The mean diameter of the metastases was 6.3cm (3.2-11.3cm). The types of operation included total caudate lobectomy (6 cases), total caudate lobectomy combined with extended hepatectomy (9 cases) and partial caudate lobectomy (3 cases). The mean operative time was 198min (154-360min) and the average intraoperative blood loss was 975ml (400-3250ml). No intraoperative death occurred, while the remarkable complications were found in 5 cases (27.8%). The survival rates of follow up for 1, 3 and 5 years were 83.3%, 61.1% and 27.8%, respectively. Conclusions The metastases on caudate lobe of liver after colorectal carcinoma resection usually involve all the hepatic portals. Surgical resection, though sophisticated in technique, remains to be a safe and effective treatment, and the first choice for treating metastases.

Radioactive Protective aprons are used to reduce radiation dose during fluoroscopy and exposure.Tears,cracks and holes can be detected by X-ray inspection.By establishing the rejection criteria,routine inspection and renew,the radioactive safety can be acheieved.

Objective To investigate the relationship between carotid artery calcification and ischemic stroke.Methods The demographic data,vascular risk factors and clinical features of patients with acute ischemic stroke and non-acute stroke patients admitted in the same period were collected retrospectively.All the patients received 64-slice spiral CT examination,and the scan data were transmitted to a GE workstation.A smart score software was used to evaluate carotid artery calcification.Multivariate logistic regression analysis was used to identify the independent risk factors for ischemic stroke.Receiver operator characteristic (ROC) curve was used to analyze and determine the predictive value of carotid artery calcification in acute ischemic stroke.Results A total of 86 patients with acute ischemic stroke and 89 with non-acute stroke (control group) were enrolled.In addition to the previous stroke history,there were no significant differences in age,gender,and vascular risk factors between the ischemic stroke group and the control group.The calcium score (338.57 ± 77.35 vs.147.79 ± 64.52; t =4.065,P =0.045),total calcified volume (372.22 ± 78.73 mm3 vs.197.27 ±61.12 mm3; t =4.740,P =0.031),and calcification quality (70.33 ± 13.83 mg vs.32.44 ± 12.27 mg; t =6.673,P =0.011) of the ischemic stroke group were significantly higher than those of the control group.In patients with ischemic stroke,there were no significant differences in the carotid artery calcification score (335.50 ± 85.95 vs.312.73 ± 90.61; t =0.052,P =0.820),total calcified volume (357.91 ± 88.93 mm3 vs.311.71 ± 81.43 mm3; t=0.071,P=0.791),and calcium quality (59.68± 17.36 mg vs.51.29 ± 18.69 mg; t =0.071,P =0.791) between the symptomatic sides and non-symptomatic sides.Multivariate logistic regression analysis showed that the carotid artery calcification score (odds ratio [OR] 4.963,95％ confidence interval [CI] 5.932-18.994; P=0.019),total calcified volume (OR 5.967,95％ CI 3.940-14.993; P =0.015),and calcium quality (OR 6.815,95％ CI 4.703-21.946; P =0.007) were the independent risk factors for ischemic stroke.The ROC curve analysis of carotid artery calcification score showed that when it was 231.25,it had a predictive value for acute ischemic stroke.The sensitivity was 85.4％,specificity was 89.9％,positive predictive value was 87.1％,and negative predictive value was 89.1％.The area under the ROC curve was 0.891 (95％ CI 0.808-0.913; P =0.027).Conclusions Carotid artery calcification is one of the independent risk factors for ischemic stroke.Carotid artery calcification score has some predictive value for acute ischemic stroke.

Objective To discuss the illness mechanism and the reason of defective energy of the stomach and intestines with acute panereatitis.Method 43 cases of acute pancreatitis was studied which had the stomach and intestinal insufficiency to determine lesion degree of the stomach and intestines acording to the change of abdomen signs.Results The data found that the patient of light acute pancreatitis had light abdominal distention,cirumscribed abdominal tenderness and rebounding pain,weaken gurgling sound;most advanced acute pancreatitis had severe abdominal distention,abdominal tenderness and rebounding pain,almost no gurgling sound.Conclusion Abdominal sign could be a indicator to determine patient's condition of acute pancreatitis and a standard to diagnose acute pancreatitis.

Objective To compare the efficacy of patient-controlled epidural analgesia(PCEA) and routine analgesia on treatment of bleeding in patients prostate pit after prostatectomy.Methods 82 patients underwent prostatectomy were randomly divided into two groups:patient-controlled epidual analgesia(n=40) and routine postoperative analgesia (n=42).Results As compared with control group,the rate and duration of bladder spasm were reduced significantly in PCEA group(P

Objective To investigate the therapeutic time window and the dose response effects of epirubicin on the expression of c-FLIP in breast cancer.Methods MCF-7and MDA-MB-231 breast cancer cells were divided into two groups: epirubicin groups were treated with 4.0,2.0,1.0,0.5 and 0.25mg/L of epirubicin,and control groups were treated with 0.9% sodium chloride solution at the same dose.After treatment for 24,48 and 72 h,the incubated cells were collected for the measurement of c-FLIP by RT-PCR,and for examination of percent of apoptosis cells with flow cytometry.ResultsA dose-time-dependent pattern was observed.The expression of c-FLIP in MCF-7and MDA-MB-231 breast cancer cell lines declined gradually as the epirubicin concentration increased and treatment time was prolonged.Percentage of apoptosis breast cancer cells increased gradually as the epirubicin concentration was increased and treatment time was prolonged,and percentage of apoptosis cells was the highest when breast cancer cells were treated with 2 mg/L epirubicin for 72 h.ConclusionsEpirubicin can promote apoptosis of breast cancer cells by inhibiting the expression of c-FLIP,and its inhibitory effect is most pronounced when breast cancer cells are treated with 2 mg/L epirubicin for 72 h.

Objective To observe the morphological characteristics of oval cells in human chronic liver diseases, and determine whether there is a relationship between the number of oval cells and liver fibrotic stage. Methods Oval cells were detected in paraffin bedded liver sections of 3 normal subjects (as controls) and 29 chronic liver diseases, using histoimmunochemistry. Cells were counted if they fulfiled the morphological criteria for oval cells and showed cytoplasmic staining. Results Oval cells were not observed in normal livers. In chronic liver diseases, oval cells were located predominantly in the periportal region and fibrosis septa, characterized by an ovoid nucleus, small size, and scant cytoplasmic. The number of oval cells increased significantly ( F=22.60, P
