Objective To investigate the diagnosis and treatment for biliary papillomatosis. Methods 23 patients who were pathologically diagnosed as biliary papillomatosis and treated in our hospital from Jan. 2003 to Mar. 2008 were enrolled in this study. Their ages, genders, clinical manifestations, diagnostic approaches,histopathological findings, intraoperative findings, treatments and prognosis were analyzed retrospectively. Recal manifestations were abdominal pain (83.3%) and obstructive jaundice (72.2%). All the patients were diagnosed pathologically through intraoperative frozen section. No patient was diagnosed preoperatively. Anatomically, solitary lesion was observed in 10 patients (43.5%) and multiple lesions in 13 patients (56.5%), with a median tumor size of 2.6 cm. Microscopically, carcinomatous change was found in one patient, mild atypical hyperplasia in three, and medium atypical hyperplasia in one. Therapies mainly included radical excision and palliative external drainage. All but one patient recovered well postoperatively. This patient had anastomotic leak. All 23 patients were followed up with a mean period of 34 months. During the follow-up, three patients died as a consequence of biliary malignancy, one patient had the recurrence and others without recurrence. Conclusions Biliary papillomatosis is very difficult to diagnose preoperatively and the definitive diagnosis mainly depends on intraoperative and postoperative pathologic examination. To obtain a better prognosis, management should be aimed at radical excision. Intraoperative cholangioscopic evaluation and frozen section are strongly recommended to guide the choice of appropriate therapeutic approach.

Objective To determine the effect of omental flap wrapping of pancreaticoduodenectomy on postoperative pancreatic fistula and intra-abdominal bleeding in patients undergoing pancreaticiduodenectomy through meta-analysis of published studies.Methods Articles about whether omental flap wrapping could prevent postoperative pancreatic fistula and intra-abdominal bleeding were searched in databases of MEDLINE,PUBMED and EMBASE.14 English article were found and according to including and excluding criteria,4 eligible articles with a total of 2971 patients were selected.Random effects model was used to analyze odds ratios and 95％ confidence intervals (CIs).Results 1129 patients were in omental wrapping group,and 1842 patients in nonomental wrapping group.Omental roll-up during pancreaticoduodenectomy could not prevent postoperative pancreatic fistula (OR =0.81,95 ％ CI 0.40～1.63,P＞0.05) or postoperative abdominal bleeding (OR=0.67,95％ CI 0.28～1.59,P＞0.05).The sensitivity analysis showed the pancreatic fistula rate was lower in the nonomental roll-up group than that in the omental roll-up group (OR=1.24,95％ CI 1.03～1.50,P＜0.05).Conclusions Omental wrapping can not decrease the risk of pancreatic fistula and abdominal bleeding after pancreaticoduodenectomy.Further randomized controlled trials are needed to identify the effect of omental wrapping technique for pancreaticoduodenectomy.

Objective: To observe the efifcacy and safety of bivalirudin on primary percutaneous coronary intervention (PCI) in patients with acute ST-elevation myocardial infarction (STEMI).
Methods: A total of 159 patients with acute STEMI treated by emergent PCI in our hospital from 2011-09 to 2014-01 were retrospectively studied. The patients were divided into 2 groups according to procedural bivalirudin application as Bivalirudin group and Heparin group, and the application of GPI (glycoprotein IIb/IIIa inhibitor) was decided by the operator. The baseline condition, coronary artery imaging condition, peri-operative and 30-day post-operative bleeding, the occurrence rate of MACE were compared between 2 groups.
Results: There were 153 patients completed the follow-up study including 72 in Bivalirudin group and 81 in Heparin group. The peri-operative bleeding rates in Bivalirudin group and Heparin group were 6.5% vs 11.0%, the in-stent thrombosis rates were 0% vs 1.2%, 30-day post-operative bleeding rates were 9.7% vs 13.5% and the occurrence of MACE were 1.4% vs 7.4% allP>0.05.
Conclusion: THE application of bivalirudin in emergent PCI is safe and effective in patients with acute STEMI, it has certain trend to reduce bleeding in relevant patients.

Objective:To study the preparation methods of N3-O-toluyl-flulorouracil (TFu) solid lipid nanoparticles(SLNs) and chitosan modified TFu SLNs. Methods: TFu-SLNs and chitosan modified TFu-SLNs were prepared by film dispersion-homogenization methods. The morphology, particle diameter and zeta potential were detected. The preparation methods were optimized by single factor experiments and an orthogonal design, and the stability of the nanoparticles was also studied. Results: The mean diameter of TFu-SLNs was 160. 2nm, and the zeta potential was -33. 2 mV. The mean diameter of chitosan modified TFu- SLNs was 400. 3nm, and the zeta potential was +12. 87 mV. With the concentration increase of chitosan, the zeta potential was enhanced. The optimized TFu-SLNs had higher reproducibility and stability. Conclusion:The formula of TFu-SLNs is optimized by an orthogonal design to obtain the optimal formula of TFu -SLNs and chitosan modified TFu-SLNs.

OBJECTIVETo observe the clinical efficacy difference in treatment of functional dyspepsia (FD) between syndrome differentiation based acupuncture and ordinary acupuncture.

METHODSSeventy FD patients were assigned to a syndrome differentiation based acupuncture group (Group A) and an ordinary acupuncture group (Group B) by Excel Software randomization. Zhongwan (RN12 ), Tianshu (ST25), and Zusanli (ST36) were needled as main points for patients in Group A. Meanwhile, different combined acupoints were needled according to syndrome differentiation. Only the same main points were needled for patients in Group B. All patients were needled once per day, 30 min each time, 6 days as one treatment cycle, 2 treatment cycles in total. Fasting serum levels of gastrin (GAS) and motilin (MTL) were determined before treatment and after 2 treatment cycles. 36-item Short-form Heath Survey (SF-36) and Nepean Dyspepsia Index [NDI, including Nepean Dyspepsia Symptom Index (NDSI) and Nepean Dyspepsia Life Quality Index (NDLQI)] were assessed before treatment, after 2 treatment cycles, and one month after treatment.

RESULTSCompared with before treatment in the same group, serum levels of GAS and MLT increased in the two groups after 2 treatment cycles (P <0. 05), but changes were more obvious in Group A (P <0. 05). Compared with before treatment in the same group, SF-36 and NDLQI score increased, and NDSI score decreased in the two groups after 2 treatment cycles and 1 month after treatment (all P <0. 05). Compared with Group B, SF-36 and NDLQI score increased in Group A after 2 treatment cycles and 1 month after treatment (P <0. 05, P <0. 01). But NDSI score at 1 month after treatment was lower in Group A than in Group B (P <0.01).

CONCLUSIONSyndrome differentiation based acupuncture could evidently improve dyspeptic symptoms of FD patients, and significantly improve their quality of life with remarkable curative effect.

ObjectiveTo observe the effects of a modified version of constraint-induced movement therapy (CIMT) on upper-extremity function of children with hemiplegic cerebral palsy.Methods22 patients were divided randomly into treatment group (n=10) and control group (n=12). Cases of control group received routine rehabilitation therapy, otherwise, those of treatment group were treated with CIMT. It involved restraining the unimpaired extremity with a restraining-instrument, and having the child engage in activities with the involved extremity 4 hours a day for 2 months repeatedly. Before and after treatment, affected upper-extremity function of all children were assessed with the Fine Motor Function Measure (FMFM) scale.ResultsThe fine motor function of all children in two groups improved significantly(P<0.05), but effect of treatment group was better than that of control group (P<0.05).ConclusionThe treatment of CIMT can improve upper-extremity function of children with hemiplegic cerebral palsy.

Intensifying the continuing education of doctors in hospitals at primary level is one of the important measures for increasing their specialized skills and improving the condition of primary care.In recent years,following the trend of national medical reform,the Fourth Military Medical University (FMMU) has made full use of its advantages to provide training for civilian doctors in hospitals at primary level.In the training,with the reform measures of ‘ four focuses' and ‘ five combinations',FMMU actively advanced teaching reform to make innovations in curriculum system and teaching methods,which was approved by teachers and students.These measures were very effective,which in turn greatly enhanced the ability of the doctors and training quality.This practice obviously pushed forward development of primary-level medical and health-care service in Shanxi province.

OBJECTIVETo observe the expression of Ginkgo biloba Tablet (GbT) on scavenger receptor A (SRA) of the aortic wall and changes of serum inflammatory factors in atherosclerotic rats, and to explore its new mechanism for fighting against atherosclerosis (AS).

METHODSTotally 45 male Wistar rats were randomly divided into the control group, the model group, the GbT group, 15 rats in each group. Levels of blood glucose, blood lipids, blood calcium, serum C-reactive protein (CRP), soluble intercellular adhesion molecule-1 (slCAM-1), and soluble vascular cell adhesion molecule-1 (sVCAM-1) were measured in all rats. The expression of SRA in the aortic wall of atherosclerotic rats was observed by immunohistochemical assay. The correlation between the expression of SRA and levels of in-flammatory factors was also observed.

RESULTSCompared with the control group, blood glucose and blood calcium obviously increased (P < 0.05); levels of TG, TC, and LDL-C were significantly elevated (P < 0.01); neointimal areas were significantly thickened, increased intima percentage was significantly enlarged, narrowed lumen index was significantly reduced; levels of CRP, sICAM-1, and sVCAM-1 were significantly elevated in the model group (all P < 0.01). Compared with the model group, blood glucose and blood calcium obviously decreased (P < 0.05); levels of TG, TC, and LDL-C significantly decreased (P < 0.01) in the GbT group. Aortic lumens were obviously narrower in the model group than in the GbT group (P < 0.05). SRA expressed at the aortic wall. The aforesaid 3 indices were significantly improved in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were significantly decreased in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were positively correlated with the percentage of SRA positive expression area (r = 0.701, 0.604, 0.581, all P < 0.01).

CONCLUSIONSSerum levels of inflammatory factors in atherosclerotic rats were elevated, and the expression of SRA in the aortic wall was enhanced. The expression of SRA was closely correlated with serum levels of inflammatory factors. GbT could decrease serum levels of inflammatory factors and inhibit the expression of SRA.
