Objective To investigate the apoptosis of human bile duct carcinoma cell induced by Apoptin gene transfection in vitro. Methods Apoptin gene was amplified by polymerase chain reaction (PCR) and then inserted into pAdtrack-CMV containing green fluorescent protein gene through T4 DNA ligase. The reconstructed plasmids were identified by enzyme digestion and sequencing. Apoptin expression vector was transfected into human bile duct carcinoma cell line QBC_(939). The apoptosis of human bile duct carcinoma cell induced by Apoptin gene was detected by TUNEL. Results Reconstructed pAdtrack-CMV containing Apoptin gene was obtained successfully. TUNEL test showed that there was significant difference in apoptosis index between Apoptin gene transfection and the control group (P

We introduced Case based learning into traditional bilingual teaching, dividing the hepatobiliary surgery teaching into four phases: preview, introduction, group discussion and estimation after class . Through the classroom organization analysis of common cases of liver and gallbladder surgery, we took students as the main body, teacher as the guide, to complete the bilingual teaching. Auxiliary case based learning used in bilingual teaching of liver and gallbladder surgery practice is beneficial to improving the quality of bilingual teaching, and helps to cultivate the students' clinical thinking. However, there are still some deficiencies of the case aided bilingual teaching, which needs continuous improvement.

Objective To understand the dietary intake of pregnant women, and try to give a reasonable sug-gestion to promote fetal development. Methods 400 pregnant women in Fushan city were enrolled in this study and their dietary intake were investigated, then the software of Analysis of pregnancy nutrition guidance system was used to make nutrition analysis. Results The ratio of the energy in each pregnancy provided by dietary protein, carbohy-drate and fat were relatively appropriate. But the intake of dietary calcium, ferrum, zinc, vitamin B1 and vitamin B2 in early pregnancy were very low, the intake were respectively 764.51 mg, 26.94 mg, 15.71 mg, 1.12 g, 1.13 g. Each pregnancy the ratio of high-quallty protein in total protein intake were more than 50%, an average protein RNI% was 48.50%. Conclusion The dietary style of pregnant women is relatively reasonable. But they should strengthened nutritional guide to intake more calciuro,ferrum, zinc,vitamin B1 and vitamin B2.

Objective To investigate the therapeutic measures of unresectable primary liver cancer (PLC) with transcatheter arterial chemoembolization(TACE).Methods The clinical data,treatment measures and followed up data of 312 patients with unresectable primary liver cancer from January 1991 to March 2010 were analyzed retrospectively.Of these 312 patients, different dosages, measures of transcatheter arterial chemoembolization together with immunotherapy and nutritional support treatments were given to the patients according to their own statements, including the patency of portal vein (evaluated by portography), the range, blood supply and lipiodol concentration of the lesions (evaluated by hepatic arteriography), and the systemic conditions.Some of these patients also accepted cryotherapy, radio frequency ablation (RFA), percutaneous ethanol injection therapy.Results Two hundred and eighty-seven patients were followed up (92％).Forty-two cases accepted the two-stage operation as the lesions were localized or reduced.In these 42 patients, 34 cases accepted the hepatectomy, 8 cases accepted the cryotherapy.The 1,3 and 5 year survival rate of all patients were 87.6％, 33.1％ and 13.2％.Conclusion TACE for unresectable primary liver cancer should be used individually and comprehensivly.Surgical treatment should be taken once the lesions can be resected.

Objective To study the therapy for xenograft human bile duct cancer in mice mediated by adenovirus containing Apoptin gene.Methods Subcutaneous human bile duct cancer was established in nude mice.Variations of tumor volume and histomorphology,side effects were observed after intratumoral injection of adenovirus containing Apoptin gene.Finally the mice were sacrificed for calculating the ratio of antitumor.Results Twelve days after treatment,the mean volume of the xenograft human bile duct cancer in the group of intratumoral injection of adenovirus containing Apoptin gene was(92.31?28.31)mm,which was reduced significantly compared with that of adenovirus infection without apoptin gene(288.86?113.13)mm and control group(344.86?113.87)mm.The ratio of antitumor was 72.10%,which was significantly higher than that in control group(11.9%).During the whole experimental course,no side effect was observed.The histological results demonstrated that the reduction of tumor growth was the result of apoptosis in bile duct cells,which was reduced by transfection of Apoptin gene.Conclusion The adenovirus vectors containing Apoptin gene may constitute a safe tool for the treatment of cholangiocarcinoma.

Objective To evaluate the efficacy of Grosse Kempf interlocking intramedullary nailing (Grosse Kempf IIN) and AO plate in the treatment of tibial fractures. Methods A retrospective analysis was done on the recovery of 55 cases with tibial fractures treated with the Grosse Kempf IIN (Group A) and 40 treated with AO plate (Group B) from 1994. Results The 10 26 months follow up showed that the healing rate and the infection rate were 98.2% (54/55) and 1.8% (1/55) respectively in the Group A with a mean healing time for 5.6 months and 90.0% (36/40) and 12.5% (5/40) respectively in the Group B with a mean healing time for 7.5 months. Conclusions The Grosse Kempf IIN has obvious advantage of excellent biodynamics, reliable fixation, simple operation, less trauma on regional blood supply and is more effective in the treatment of tibial fractures than the AO plate. Nevertheless, I IN itself has limitation for further application.

Parpose:To observe the therapeutic effects of the ricin's intervention in treating the hepatic carcinoma and to compare the restraint effect to bone manrrow caused by ricin and mitomicin C.Materials and Methods:Use human grafted hepatic carcinoma to naked rat as transplanted rat's liver cancer model.The therapeutic effects of ricin(4?g/kg)were compared with that of lipiodel-emusified riein(8?g/kg)and mitomicin C(500ug/kg)(all the dosages were of the one third of the LD50),with saline injected liver cancers as the control.To observe the tumour's growth inhibition rate,-FP hemogram and marrow change.Results:The growth of turners in group of ricin,lipiodel-emulified ricin,mitomicin C was inhibited,result in tumour necrosis.The inhibition in marrow showed more obvious in mitomicin C than in ricin.The- FP's reduction was significant in comparision with that of the control group,however,there were no remarkable difference among the three drug forms.Conclusion:Ricin has remarkable therapeutic effect on hepatic carcinoma.Ricin's emulsion was stable providing experimentd basis for the toxicity to marrow is clearly lower than mitomicim C

Objective To assess the clinical history and MRI findings of pituitary adenoma of different hormonesecreting type.Methods We retrospectively studied 200 postoperated patients,from 1996 to 2000,who all had the preoperated MRI exams.All cases had histopathological evalutions.Both clinical presentation(age,sex,symtom,sign)and MRI findings(size,form,signal intensity,extension)were investigated.Results There was a great span of age with sixty percent owing for 35～55 years old.The male and female proportion was 1∶2 in PRL hormone-secreting pituitary adenoma.12 cases with luleinizing hormone-secreting and 2 cases with thyrotropin hormone-secreting pituitary adenoma were just male.In other types the incidences were similar in man and woman.Clinical symptom and sign present overlapping.The volume of tumor was from 0.5 cm?0.8 cm?1 cm to 6 cm?7 cm?8 cm with most multihormone adenoma's maxium dimension out of 5 cm.The signal intensity was not characteristic pre-and post-enhancement.No calcification could be seen.In term of extension,most was to suprasellar,then infrasellar,unilateral or bilateral sinus cavernous,last was to lower part of the third ventricle.Conclusion Different hormonesecreting pituitary adenomas have some speciality in clinical and MRI presentation.Although an accurate diagnosis can not be made according to it,more information have been obtained.

Objective To obtain magnetic resonance imaging(MRI) symptoms that could be used in medical diagnosis and identification by analyzing the diverse MRI appearance of brain multiple sclerosis(MS).Methods MRI findings of 41 samples of clinically definite MS, including the numbers, distributions, sizes, and shapes of the lesions were analyzed. The symbolic characteristics and enhanced expression are also covered.Results Brain MS might happen singly and multiply, and more frequently with multiple happening. In a multiple case, 4—15 lesions were observed the most. Some samples showed with diffuse lesions which were unable to be counted accurately presenting as a “dirty-appearing white matter”. The distribution of the lesions was observed most frequently at the two sides of periventricle, and following by the subcortical, corpus callosum, and brainstem. Only two lesions were observed at cerebrum. The size of most lesions range from a few millimeters to 2 cm, accounting for about 75% of the total samples. Lesions with size above 2 cm were seen seldomly, with the biggest one of 6—7 cm. According to the shapes and symptoms, lesions might be categorized as an acute and chronic ones. The acute lesions had a shape of oval or circle, with a swelling appearance, low signal of T_1WI, and isointensity or a slightly higher signal on the circle. T_2WI showed a high signal, with different increase and showing “core+lunar” sign. This kind of lesions showed an enhancement with the circle enhancement as the most typical one, which had a complete circle or non-conplete arc shape enhancement, even the big lesions. The chronic lesion might also be divided into two categories. One was the quasi-symmetric lesion, with the distribution along two sides of periventricle and with the shape of small puncture/patch, part of them merged into the big patch; another kind of lesions was found scattered sparsely at frontal, parietal lobes and two sides of the periventricle, with small patches in shape. The chronic lesions had an appearance of shrinking, sharp edge, even signals, and had no lunar circle phenomena and obvious enhancement.Conclusion Brain MS have diverse MRI appearence, with some of which are unique and symbolic.

Studies using isolated rat fundus strip preparation demonstrated that l-stephanine ( l-STP ) , l-roemerine ( 1-REM ), l-stepholidine (l-SPD), 1-tetrahydropalmatine ( l-THP ) and dl-tetrahydrode-berine ( THB ) possessed 5-HT blockade properties. 1-STP ( 16, 25 ?M ) produced competitve antagonism against 5-HT receptor on rat fundus, while higher concentration ( 50 ?M ) suggested a non-competi tive inhibition, with pA2' and2' values equal to 5.8 and 4.2 respectively. 1-REM was found to be a non-competitive antagonIst ( pD' 2 = 4.5). 1-SPD, 1-THP and THB cuased a parallel shift to the right of 5-HT concentration response curve without any significant changes in their maximum response, indicating that they were competitive antagonists of 5-HT receptor. The antagonistic potencies of 1-SPD, l-THP and THB were expressed as pA2 values: 6.2,5.2 and 5.0.
