There are a lot of medical colleges which carry out foreign student medical education in our country. On the basis of clinical theory situation and problems of foreign students medical education,Xuzhou Medical College implemented a number of reform measures and achieved good teaching effect.These measures included writing new syllabus of oversea students and reforming multiform teaching methods and the pattern of examination and evaluation for clinical theory.

Objective To investigate the protective effect of ischemic preconditioning(IP) on liver ischemia/reperfusion(I/R)injury in rats with cirrhosis.Methods Thirty-two SD rats with liver cirrhosis induced by carbon tetrachloride were randomly divided into IP group and Non-IP(NIP) group,according to whether an IP was performed before liver I/R injury or not.The function of liver, superoxide dismutase(SOD),glutathione peroxidase(GSH-PX),malonyldialdehyde(MDA),adenine nucleotide(ATP,ADP,AMP),energy charge(EC),nitric oxide(NO)in liver tissues,the changes in liver histology,and one-week survival rate after the test in both groups were compared.Results Compared with NIP group,the serum AST,ALT ,and LDH and the MDA contents significantly decreased(P

Objective To study the clinical characteristics, diagnosis and treatment of extrahepatic growing hepatocellular carcinoma(HCC). Methods The clinical data of 11 patients with extrahepatic growing HCC were analysed retrospectively. Results The mean diameter of the tumors was (12.4?4.3)cm.All the tumors in the 11 patients had complete capsule formation. The numbers of tumors located in the left, right and caudate lobe of the liver were 6,3 and 2 respectively. Surgical treatment included segmentectomy in 6 cases , lobectomy in 4 cases, and unresectable in 1 case. The 1-, 2-, and 3-year survival rates were 80.1%,62.3%, and 47.6% respectively. Conclusions Although the size of extrahepatic growing HCC is large,the resection rate is high and prognosis is good. The resection of hepatic segments or lobes containing the lesion should be done in radical operation of this tumors.

Combined with the practice of curriculum reform in Xuzhou Medical College for for-eign clinical medical students, this paper discussed its experiences in compiling the teaching syllabus, programming rational courses, increasing practical class hours, establishing corresponding elective courses, taking various teaching methods and using flexible testing mode.

Objective To evaluate the feasibility and safety of resection of tumors in hepatic centric area. Methods The clinical data of 36 patients with tumors in hepatic centric area treated by resection in our hospital from Jan 1996 to Dec 2001 were retrospectively analyzed. In this series,there were 26 cases of liver cancer and 10 cases of benign tumor. Of the 36 patients,the tumor involved the first porta hepatis in 13 cases, involved the second porta hepatis in 10 , involved the third porta hepatis in 5 , involved both the first and second porta hepatis in 3, and involved both the second and third porta hepatis in 5 cases. Results During the operation, massive hemorrhage occurred in 4 cases(11.1%). Postoperative complications occurred in 11 patients(30.5%),including liver function failure in 1 case (2.7%), biliary fistula in 2 cases (5.5%), pleural effusion in 6 cases (16.7%), subphrenic infection in 1 case (2.7%),and abdominal incisional hernia in 1 case (2.7%). All patients recovered except that one died of acute hepatic failure after the operation. Conclusions Although the surgery for this tumor is quite difficult and risky, if enough attention is paid to the choice of the patient,and the meticulous surgical technique,the operation safety and therapeutic result of the operation could be improved.

OBJECTIVETo investigate the risk factors for contact dermatitis in pig farm workers.

METHODSThe cross-sectional questionnaire survey and on-site survey were conducted in pig farms raising more than 50 pigs in a county of Fujian Province, China. The study subjects were grouped based on different factors. The incidence rate was compared between groups by statistical analysis.

RESULTSOf 302 subjects, 70 (23.18%) had contact dermatitis. There was a significant difference in the prevalence of contact dermatitis between the subjects in direct contact with commercially available pannage and those in indirect contact (χ(2) = 14.552, P < 0.01). Region, season, farm scale, brand of pannage, and allergic history were not influential factors for contact dermatitis (P > 0.05 for all).

CONCLUSIONDirect contact with commercially available pannage is closely associated with contact dermatitis in pig farm workers.
