Long educational system is an effective form in training high-level medical talents.Doctor-patient communication skill is one of tbe basic qualifications for 8-year program medical students.Standardized patients can be applied in training and evaluating of the 8-year program medical students'ability to deal with doctor-patient relationship so as to cultivate their communication competence.

To improve the quality of clinical practice education,questionnaires were distributed to the medical interns. Corresponding responses were proposed based on humanities quality,quality of clinical practice and its factors,views on after-department examination and training for clinical skill. The result shows most of students realized the importance of clinical practice. After reformation for clinical education,after-department examination could efficiently improve interns’ability to resolve practical problems. Management of teachers,development of students’clinical thinking and ability of communication between doctor and patient should be enhanced .

Objective To study the clinical curative effect of transvaginal and laparoscopic operation methods for treating exogenous uterine cesarean scar pregnancy.Methods Sixty patients with exogenous uterine CSP in our hospital from August 2013 to August 2016 were selected and divided into the two groups with 30 cases in each group.The control group adopted laparoscopic lesion resection,while the observation group adopted transvaginal lesion excision of lower uterine segment.Then the operation situation,postoperative VAS score,β-HCG levels and traumatic response indexes were compared between the two groups.Results The hospitalization time had no statistical difference between the two groups(P＞0.05).The hospitalization cost,blood loss volume and anal exhaustion time in the observation group were less than those in the control group(P＜0.05).The β-HCG level before and after operation had no statistical difference between the two groups (P＞0.05).The VAS score and traumatic response indexes in the observation group were better than those in the control group(P＜0.05).The complication occurrence rate in the observation group was lower than that in the control group(P＜0.05).Conclusion Transvaginal lesion excision of lower uterine segment in the treatment of exogenous uterine CSP has better curative effect and safety.

BACKGROUND/AIMS: To screen for serum protein/peptide biomarkers of hepatitis B virus (HBV)-associated chronic hepatic lesions in an attempt to profile the progression of HBV-associated chronic hepatic lesions using surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS) techniques. METHODS: Using SELDI-TOF MS, serum protein/peptide profiles on the CM10 ProteinChip arrays were obtained from a training group including 26 HBV-associated hepatocellular carcinoma patients with liver cirrhosis (LC), 30 HBV-associated LC patients, 85 patients at different stages of liver fibrosis, and 30 asymptomatic HBV carriers. The most valuable SELDI peak for predicting the progression to LC in HBV-infected patients was identified. RESULTS: A SELDI peak of M/Z 5805 with value for predicting LC in HBV-infected patients was found and was identified as a peptide of the C-terminal fraction of the fibrinogen alpha-chain precursor, isoform 1. CONCLUSIONS: The peptide of the C-terminal fraction of the fibrinogen alpha-chain precursor, isoform 1 with M/Z 5805, may be a serological biomarker for progression to LC in HBV-infected patients.

OBJECTIVETo study the expression of tenascin in normal and fibrotic rat liver.

METHODSLiver fibrosis induced in rat with CCl(4) were divided into three stages: the stage of hepatic injury (4 weeks), early stage of hepatic fibrosis (8 weeks) and later stage of hepatic fibrosis (12 weeks). Tenascin expression in liver tissue was observed by immunohistochemical method and in situ hybridization using digoxigenin-labelled DNA probe.

RESULTSIn normal rat liver there was a weak staining for tenascin. In both liver injury stage and early stage of hepatic fibrosis, both mRNA signal and immunostaining for tenascin were significantly increased as compared to that in normal liver. In later stage of hepatic fibrosis, mRNA signal and immunostaining for tenascin were decreased compared with that in early stage of hepatic fibrosis. The cellular source of tenascin in liver mainly restricted in mesenchymal cells.

CONCLUSIONSTenascin is a component of the extracellular matrix of liver tissue. Plays a role in early matrix organization during liver fibrogenesis.

To establish and manage of multicentral colection bio-sample banks of malignant tumors from digestive system, the paper designed a multicentral management system, established the standard operation procedures (SOPs) and leaded ten hospitals nationwide to colect tumor samples. The biobank has been established for half a year, and has colected 695 samples from patients with digestive system malignant tumor. The clinical data is ful and complete, labeled in a unified way and classified to be managed. The clinical and molecular biology researches were based on the biobank, and obtained achievements. The biobank provides a research platform for malignant tumor of digestive system from different regions and of different types.
