Objective To explore the effect and method of the theory teaching of general practice course for eight-year program of clinical medical students. Methods The course of General Medicine was set up for 87 students from two grades in their fourth school year. All of them attended a closed-book exami-nation when they finished the lectures. The satisfaction rates, necessity and the suggestion of teaching and assessment were collected from the questionnaire. Results The examination results of the two grade students were (80.92±7.26) and (83.76±5.75); The satisfaction rate was 40.2％ (35/87); Necessity of the courses was between 3.6 to 4.1 (5-point-Likert-scale). The way of teaching method students chose was dif-ferent by course content. Conclusion The theory teaching of general practice course for eight-year program of clinical medical students needs more reform from curriculum designing, teaching methods, faculty train-ing and evaluation methods.

Peroxisome proliferator-activated receptors (PPARs) are nuclear transcriptional factors closely related to glucose and lipid metabolism, insulin sensitivity. Activation of PPARs targets treated type 2 diabetes, obesity, hypertension and other metabolic diseases by insulin resistance. Recently, a variety of active ingredients of traditional Chinese medicines (TCMs) have been proved to activate PPARs targets for improving insulin resistance, which has attracted widespread attention at home and abroad. In this paper, we reviewed the pathological mechanisms between insulin resistance and PPARs, and summarized the active ingredients of TCMs improved insulin resistance based on PPARs targets. This paper may provide some theoretical guidance for the development of new drugs and TCMs.

Objective To explore the effects of different degrees of intermittent hypoxia (IH) on the activation and the secretion of extracellular matrix in MLg lung fibroblast cell line. Methods MLg lung fibroblast cells in logarithmic growth phase were exposed for 5%O2 for 100 seconds and 21%O2 for 120 seconds in 1 h, 4 h and 8 h groups (IH1, IH4 and IH8) and normoxia group (21%O2 for 8 h, N group). The cells in each group were collected at the end of experiment. Real-time PCR was used to measure the mRNA expression levels ofα-SMA and typeⅠcollagen (COL1) A1, and Western blot assay was used to detect the protein expression levels ofα-SMA and COL1. Results The mRNA and protein expression levels ofα-SMA and COL1 were significantly increased in IH1, IH4 and IH8 groups than those in N group (all P < 0.05). Furthermore, expression levels of α-SMA and COL1 showed a time-dependent increase with IH exposure time. Conclusion The intermittent hypoxia can promote the cell activation and the extracellular matrix secretion of mouse lung fibroblast cells, which may be related with the oxidative stress.

Objective To explore the effects of cobalt chloride (CoCl2)-induced hypoxia on migration of melanoma cells, and to detect the transcription, expression and secretion of Follistatin-like 1(FSTL1) in this process. Methods B16F10 melanoma cell line was treated with CoCl2 in order to mimic hypoxia. Experimental cells were divided into three groups: 0μmol/L, 50μmol/L and 100μmol/L CoCl2 treatment groups. MTT assay was used to assure cell viability, and to determine the treatment concentration of CoCl2. Transwell assay was used to determine the migration ability of B16F10 melanoma cell line. Real-time PCR was used to measure the mRNA expression of Fstl1. Western blot assay was used to detect the intracel?lular and extracellular protein expression of FSTL1. Results The cell viability of B16F10 melanoma cell line was signifi?cantly reduced by CoCl2 treatment, with a time and concentration-dependent manner. The migration ability of B16F10 cell line was significantly increased in CoCl2 treated group compared with that of control group (P<0.05). The mRNA level of Fstl1 was obviously higher in CoCl2 treated group than that of control group (P<0.05). The intracellular expression of FSTL1 protein was consistent with the expression trend of Fstl1 mRNA. Simultaneously, the extracellular protein level of FSTL1 was significantly decreased compared with that of control group. There was no expression of FSTL1 in 100μmol/L CoCl2 treat?ment group. Conclusion The migration ability of melanoma cell line is enhanced by CoCl2 treatment, which may be associ?ated with expression and secretion of FSTL1, however, the relevant mechanism still needs further investigation.

BACKGROUND: Biological characteristics of porcine cardiovascular system are similar to that of human. The metabolism, immune system, mechanism of disease have 99% homology between pig and human. OBJECTIVE: To develop ventricular aneurysm animal models by plugging left anterior descending branch. DESIGN, TIME AND SETTING: The animal observational study was performed at the Laboratory of Functional Material and Animal Experimental Center, Tongji Hospital Affiliated to Tongji University from December 2005 to July 2007. MATERIALS: A total of 13 pigs, of both genders, weighing 30-40 kg, were used in this study. METHODS: After abdominal cavity and intravenous anesthesia, balloon with "WYW" stent was put into 13 pig left anterior descending coronary artery following No. 7 artery sheathing canal was implanted. The balloon was dilated and the stent was positioned into the distal point of the first diagonal branch to obstruct the artery under digital subtraction angiography. During and after the operation, electrocardiogram was monitored and recorded to maintain stable vital sign. MAIN OUTCOME MEASURES: Electrocardiogram, serum myocardial enzymes, myocardial radionuciide imaging, echocardiography and angiography and pathological changes were observed. RESULTS: One rat died of anesthetic accident before surgery. Six rats died from ventricular fibrillation during plugging, and the other 6 rats were survival. 4 weeks following surgery, coronary angiography showed blood flow at distal end was blocked 100%. Left ventricle angiography demonstrated that wall motion at apex of the heart and the left ventricle disappeared. Before embolism, electrocardio-monitoring displayed electrocardiogram was normal. After plugging, ST segment was raised continuously; amplitude of R wave was decreased; T wave was erected; ST-T fusion wave appeared; precordial leads were obvious. ST segment was reduced to basic level 2 week later, and pathological Q wave appeared 4 weeks later. Serum treponin was increased at 12 hears following surgery compared with before surgery (P < 0.01). Radioactive nuclide myocardial imaging revealed that cardiac apex and left ventdcle anterior wall showed radioactive nuclide perfusion filling defect, thin ventricular wall and ventricular aneurysm. Cardiac ultrasonic showed six pigs suffered from weaken segmentation contraction motor of local ventricular wall, especially at anterior wall of the left ventricle and cardiac apex. After hematoxylin-eesin staining, optical microscope exhibited that cardiac muscle fiber disappeared, which was replaced by collagen fiber, with the presence of some capillary at the infarct of cardiac apex. Pyknosis and lysis of residual cardiac muscle fiber were visible in infarct region of anterior wall of the right ventricle. Many inflammatory cells and capillary infiltration were detected besides collagen fiber filling. CONCLUSION: The new approach of "WYW" intervention embolization is able to develop the ventricular aneurysm animal model, which is similar to clinical pathophysiological variation. The outcome is precise and reliable.

Objective To investigate the diagnosis and treatment of primary hyperparathyroidism (PHPT) with urolithiasis.Methods The clinical data of 9 PHPT patients who were evaluated with simple metabolic evaluation in 881 urolithiasis from 2000 to 2005 were summarized and the references were reviewed.Results The level of serum calcium was (2.96±0.48)mmol/L before operation, (1.94±0.42) mmol/L after operation.The level of parathyroid hormone(PTH) was(1133.53±788.21)pmol/L before op-eration,(74.52±49.17)pmol/L after operation.The level of serum calcium and PTH changed significantly after the parathyroidectomy (P<0.01).Follow-up for 14 months to 6 years.the ureteral stones fragments with lithotripsy were clear after 3 months and followed without recurrence,although the renal stones without lithotripsy were followed with no significant change.Conclusions Increase of serum calcium or increase of PTH above double with normal serum calcium may be helpful for diagnosis of PHPT with urolithiasis.Ureteral stone with PHPT should be treated together.Renal stone with PHPT may be followed up after the parathv-roidectomy,and be treated until the complications were occurred.It suggests that the maidend diagnosed pa-tient with urolithiasis should be added with simple metabolic evaluation,including serum calcium, phospho-nium and PTH.
