Objective To assess the value of three clinical diagnostic criteria systems,the APACHE-Ⅱ,Balthazar score and Extrapancreatic inflammation on Abdominal Computed tomography(EPIC) in predicting outcome of patients with acute pancreatitis.Methods One hundred and seventy-eight patients with acute pancreatitis who underwent an abdominal CT scan within 24 h after admission were studied prospectively in the study.To assess the value of predicting severe AP and complications,the APACHE-Ⅱ score,the Balthazar score,EPIC score were calculated and evaluated by calculating receiver operator characteristic(ROC)curves,the sensitivity,the specificity,the Youden Index and the area under the ROC curve.Results 46 of 178 patients developed severe disease.The mean score of the three criteria system was significantly higher in the group of severe AP than the mild AP one(P

Objective To explore the CT and MR features of malignant peripheral nerve sheath tumor (MPNST) of adults.Methods The CT and MRI findings of 20 patients of MPNST confirmed by pathology were analyzed retrospectively.Results Among 20 cases,the lesions were located in the lower extremities (n=4),shoulder and spine (n=4),abdomen (n=3),chest wall (n=2),mediastinum (n=2),breast (n=1),prostate (n=1),scrotum (n=1),scalp (n=1),left maxillary sinus and orbital bottom (n=1).Nineteen cases appeared as solid masses and 1 case appeared as diffuse lesion.The maximum cross section of the lesions were about 1.41 cm× 1.42 cm-17.10 cm× 18.08 cm.Sixteen cases were ill defined margin and 4 cases were well-defined margin.CT scan showed 14 cases were lower density or isodensity and with patchy inhomogeneous density.Multiple calcification were found in 2 cases and osteolytic destruction were found in 7 cases.Enhanced CT of 10 cases showed solid component and gradually delayed enhancement,while cystic lesion and necrosis were not enhancement.The tortuous arteries were displayed in 7 cases.Seven cases were performed MRI and the lesions appeared as hypo-intensity on T1WI and hypo-intensity on T2WI with obviously high intensity of cystic component.Enhanced MRI of 3 cases showed significantly heterogeneous enhancement,cyst and necrosis had no enhancement.MR dynamic enhancement of 1 case showed time-signal intensity curve was platform type.DWI showed high signal.Conclusion MPNST has certain CT and MR characteristics which are helpful to improve the diagnostic accuracy.

Objective To explore the application of team-based learning (TBL) and problem-based learning (PBL) method in clinical teaching of laparoscopic surgery in general surgery. Methods 48 students of surgery in our department were selected as the subjects to conduct the clinical teaching study. These students were divided randomly into two groups. The experimental group (24 students) adopted the method that combined TBL and PBL method, while the control group (24 students) adopted the traditional teaching method. We compared the efficacy of two groups in term of theoretical knowledge, surgical practice, com-prehensive surgical grade, and questionnaire survey. Results The score of theoretical knowledge and sur-gical practice on clipping soybean and making suturation and instrumental tie of two groups were obviously higher than that before teaching. After finishing teaching, the score of experimental group on theoretical knowledge, making suturation and instrumental tie and comprehensive surgical grade were higher than that of control group. The score of clipping soybean was similar between two groups. In addition, in term of questionnaire survey on the consciousness of independent study, the depth and width of study, and satisfac-tions to teaching, the TBL and PBL group had a better score than the control group. Conclusion The new teaching method which combines TBL with PBL enhances the teaching effect on theoretical knowledge and laparoscopic surgery practice. It is an effective method to train medical students.

Objective To determine the effects of different anesthetic techniques on T-lymphocyte subsets in patients with esophageal carcinoma. Methods Forty patients were randomly assigned into general anesthesia group (group Ⅰ),or combined generae anesthesia with epidural anesthesia group(group Ⅱ). Peripheral blood CD3, CD4,CD8 were measured before induction ( T1 ), after anesthesia ( T2 ), end of operation ( T3 ), 1d ( T4 ), 3d ( T5 ) after surgery. Resolts CD3,CD4,CD8,CD4/CD8 decreased at T2 in the two groups. In group Ⅱ ,CD3,CD4,CD8,CD4/CD8 ratio almost returned to the baseline values at T4 ,while group Ⅰ did not. Conclusion Epidural anesthesia combined with general anesthesia can reduce depression of T-lymphocyte subsets induced by surgical trauma and anesthesia, and is the anesthetic tecnique of choice for cancer patients undergoing major operation.

To explore and compare the response of the protease inhibitors or non-nucleoside reverse transcriptase inhibitors-based therapeutic impact on metabolic indices in hepatitis C virus (HCV)/human immunodeficiency virus(HIV) co-infected patients.A randomized,open,and control approach was performed to enroll 273 cases of HCV/HIV co-infected patients on their initial visits and to choose protease inhibitors(PIs group) or non-nucleoside reverse transcriptase inhibitors (NNRTIs group) based therapy treatments for one year.Laboratory results of metabolic indices before and after the treatment were collected.After treatment,the levels of triglyceride in NNRTIs and Pls groups were (1.93 ± 0.99) mmol/L and (1.62 ± 0.93) mmol/L respectively,high density lipoprotein-cholesterol were(1.28 ± 0.55) mmol/L and (1.08 ± 0.53) mmol/L,low density lipoprotein-cholesterol were (2.60 ± 1.44) mmol/L and (2.22 ± 1.16) mmol/L,fasting plasma glucose were (5.92 ± 1.21) mmol/L and (4.79 ± 0.47) mmol/L,serum creatinine were (70.5 ± 14.6) μmol/L and (56.6 ± 8.3) μmol/L,and serum amylase were(66.9 ± 27.5) U/L and(62.7 ± 33.8) U/L respectively.The difference between the two groups was statistically significant(all P＜0.01).There is a therapeutic impact on metabolic indices in patients wtih HCV / HIV co-infection after non-nucleoside reverse transcriptase inhibitors-based regimen.

Objective To explore the chiaical value of cerebral perfusion reduction after subarachnoid hemorrhage(SAH)by multi spiral CT perfusion in rabbits.Methods 32 male Japanese big-ear rabbits of clean level were randomly divided into 2 groups:Group A(n =8),the normal group,were to obtain normal MS-CTP values of rabbit cerebrums;Group B(n =24),the SAH group was made into two-hemorrhage animal models,checked on seven day by multi spiral CT perfusion.The source data was transmitted to the post-processing workstation ADW 4.2.Perfusion parameters maps(CBF)of both sides of frontal,parietal and basal ganglia were got by computing.Each rabbit was killed immediately after scanning,and the spider blood was observed.Results The average CBF value of the two groups:The difference was not statistically significant at the frontal(t =1.740,P =0.092)and parietal(t =1.868,P =0.072); The average values of CBF were significantly decreased at the basal ganglia(t =2.481,P =0.019).Group B showed the distribution of blood clot in the basal cistern,but there was no blood clot at the frontal and parietal.Conclusion The monitor perfusion changes of rabbit brain after SAH could be detected by MS-CTP,and the lower of regional cerebral perfusion had a relationship with the distribution with the blood clot,and it could instruct the early diagnosis of cerebral perfusion,and the clinical benefit to early intervention treatment.

To investigate the efficacy and safety of minimal y invasive endovascular techniques treatment of hydronephrosis in pregnancy complicated by infection.
65 cases of pregnancy hydronephrosis coinfected patients with minimal y invasive endovascular treatment. Patients were fol owed up for 3-12 months, compared with 48 patients with the same period of conservative treatment .
Ureteral perforation and other surgery-related complications occurred in 65 patients in the observation group has not occurred. The patient's duration of hospitalization、the recurrence rate of postoperative infection, antibiotic duration of treatment, fever days were significantly lower than the control group(P<0.05).
Compared with conservative treatment, minimal y invasive endovascular technical treatment of gestational hydronephrosis co-infection with faster recovery, shorter hospital stay, can significantly reduce the number of days of fever patients and reduce the number of days of antibiotic use, can be used as conventional means of treatment of gestational hydronephrosis infection combined conventional.
