Objectives:To evaluate serum ?-HCG and VEGF concentrations in women with rupture of tubal pregnancy(rTP),tubal abortion(TA) and spontaneous abortion(SA) at about 6 weeks of gestation.Methods:This was a prospective,case-control study evaluating serum ?-HCG and VEGF concentrations among 63 women with the symptom of abdominal pain or vaginal bleeding who subsequently were confirmed rTPs(n=21),TAs(n=14),SAs(n=27).One suspected TP proved to be normal intrauterine pregnancy and was excluded.?-HCG,and VEGF were measured by RIA and ELISA methods respectively.Results:The median ?-HCG concentrations in rTPs and TAs were statistically higher than that in SAs(3070.70?1069.68,2632.21?840.60,1674.05?727.88mIU/ml respectively,P1 880 mIU/ml,serum ?-HCG could discriminate TPs from SAs with a sensitivity of 88.6%,a specificity of 66.7% and a positive predictive value of 77.5%.The median VEGF concentration in rTPs was statistically higher than that in TAs and SAs(254.87?78.52,105.81?38.11,118.32?52.94 pg/ml respectively,P179pg/ml,serum VEGF could discriminate rTPs from TAs with a sensitivity of 85.7%,a specificity of 100% and a positive predictive value of 100%.Conclusion:It is a useful marker that the combined measurement of serum ?-HCG and VEGF predicts the rupture of tubal pregnancy at about 6 weeks of gestation.

For a valid control of the finance management, the management system is developed again aiming at finance related control links and key control points. In this way, the control is rigorous and integral with simple procedures for check and examination. The key control point is set oriented to note management. Real-time operation is controlled. Post output processing is controlled. With business income and business expenditure as the main line, the control process of the related links are built up. Computer maintenance system is controlled.

Objective:To Study the molecular mechanism of Guizhi Fuling Bolus(GFW) controlling the tumor growth.Methods:Each of 30 mice received 0.2ml S180 tumor cell suspension subcutaneously in the right axilla.The mice were randomly divided into model group,GFW group and Cyclophosphane(CY) group and with 10 mice in each group.Another ten mice without cancer were used as control.The model group received intragastric normal saline,0.2ml?10g-1?d-1;the GFW group was given intragastric administration,0.2ml?10g-1?d-1 whilst the CY group received intraperitoneal injection of CY at 20mg?kg-1?d-1.The medicines were given to the mice in each group after they were inoculated,once a day for 10 days.The mice were sacrificed and the tumor removed,the S180 mice sarcoma model was used to detect the inhibiting effects of GFW.The protein expressions of P21waf/cip and mRNA expression of Survivin were evaluated by immunohistochemistry and in situ hybridization.Results:For S180 sarcoma,the inhibiting ratio of GFW was 38.93%.Survivin mRNA was markedly declined in the GFW group when compared with the model group(P

Objective To study the half quantitative diagnostic method of the high-risk gastrointestinal stromal tumors (GISTs) with analyzing the characteristic of high-risk and lower risk GISTs with multi-slice spiral CT (MSCT). Methods CT findings of 46 patients with 51 GIST lesions were retrospectively analyzed. The location, size, shape, boundary, growth pattern and other specialties of the tumors in high-risk and lower risk GISTs were studied, moreover statistical analysis was conducted, logistic regression equation was obtained. Results Significant difference was found in tumors' location, size, shape, boundary and distant metastasis between the two types of GISTs. There were obvious correlation between the risk level and tumors' size and boundary which could be used to build the diagnostic equation of high-risk GISTs. Conclusion The equation ln [P/(1-P)]=-2.612X_3+0.371X_5 (X_3:tumors' boundary, X_5:tumors' size) is valuable in the diagnosis of high-risk GISTs.

Objective To understand adolescent's mental stress, coping style and their correlating with emotion. Methods This research, in order to be tried with 5870 middle school students, adopt Mental Stress Questionnaire, Coping Style Scale and Profile of Mood States. Results Compared with male students, female students had higher scores on stress from school work achievement and appearance(P＜0.05) and lower scores on stress from family[(2.04±1.19)vs(2.11±1.25)](P＜0.05),also they had higher sores on extra-coping style[(3.11±0.77)vs(2.77±0.81)](P＜0.01). Compared with lower grade students, higher grade students had higher scores on all mental stress except stress from family, while they had lower scores on extra-coping style (P＜0.01). Stepwise logistic regression analysis indicated that high scores on mental stress and intro-coping style could predict negative emotion (P＜0.01), and extra-coping style could predict positive emotion (P＜0.01).Conclusion The middle school students suffered more stress from school work achievement than from other aspects. Students who differed in sex, grade had significant different scores on mental stress and coping style. Mental stress and coping style could predict adolescents' emotion.

This article elaborated on the importance of collecting archives of drug clinical trails. Taking the drug clinical trial archives into account, the first value is the effort of clinical researchers. Sec-ond, the archives of drug clinical trials are the requirement to obtaining the evaluation before the new drug projects are approved. Third, the archives are the important evidence as getting professional certification from relevant drug research organizations and governmental officials. Making good drug clinical archive man-agement depends on the system and relevant regulations. A system should clarify the responsibilities of the collectors and managers for the archival materials. It also should make clear what are needs for collection, the rule of project numbering, and the rule of transferring. A good system also establishes the functionalities of monitoring and controlling. Last, the article pointed out the usual problem appeared in archive manage-ment of drug clinical trials.

Objective To explore the pathological and imaging features of adenosquamous carcinoma (ASC) of pancreas.Methods Both clinical data and imaging findings in seven cases with pathologically proved ASC of pancreas were analyzed retrospectively.Imaging features were compared with pathological results.Results 1 )The disease mainly occurred in people around 55 years, among the 7 cases ,5 located in the pancreatic head, 2 in the body and tail, with abdominal pain and jaundice as the chief complaint.2)Pathologically, the solid part of the tumor was made up of ductal adenocarcinoma and squamous carcinoma components, with a different rate, while the cystic part was made up of necrosis, liquefaction.3) the imaging of 5 cases with ASC of pancreas in which squamous carcinoma components predominate shows solid and cystic tumors of pancreas, furthermore the ratio of central cystic diameter and the whole tumor diameter increase with the the volum of the tumor.4) There is no partitioning in the cystic part of the tumor, with a few irregular microcyst around it.5 ) The tumor shows a pattern of infiltrative growth, associated dilatation of the common bileduct or pancreatic duct in all cases, pancreatic atrophy in part.6) Squamous carcinoma components of the tumor was the pathologic basis for the formation of the solid and cystic structure in imaging.Conclusions ASC of pancreas is a rare aggressive subtype of pancreatic adenocarcinoma with a worse prognosis than the usual type of ductal adenocarcinoma, although symptoms similar to pancreatic ductal carcinoma.Cases of ASC of pancreas in which squamous carcinoma components predominate have certain characteristic imaging and pathologic features,which is important to early diagnosis.

Objective:To investigate the effects of IL-2 on the proliferation activity and HCG secretion of first trimester human trophoblastic cells in vitro. Methods:Growing -well 4th generation trophoblastic cells were selected,cultured for 48 h with IL-2 of different concentration. The MTT colorimetric assay was used to analyze the proliferation activity, and radioimmunoassay was used to analyze the secretion of HCG. Results:①Low concentration (100 U/ml,400 U/ml) IL-2 promoted proliferation activity and HCG secretion (P

0.05).Conclusions This study shows that in severe acute biliary pancreatitis patiens with biliary tract obstruction, emergency endoscopic therapy should be performed within 48 hours from the onset of symptoms; patients with mild acute biliary pancreatitis shoud also undergo prompt endoscopic therapy after ineffective conservative management or appearance of symptoms of acute biliary tract infection.
