Seen from the judicial fulfillment of the medical treatment indemnity,there exists a lot of dissatisfaction,which derives from the wrong application of law to a great degree.It is the reasonable and feasible choice to apply the law correctly and carry out the actual indemnification principle of the General Rule of the Civil Law in the medical treatment indemnity realm so as to promote the formation of the dispersion mechanism of the sounder medical treatment responsibility.

The paper expounds the ethics problems caused by doctor's selling activities in consulting room,which means the conflicts between doctors and patients, purchase pressure implied in seeking medical ad vice, disgrace to the aim of medical service etc. Furthermore puts forward some suggestions about strengthening management, stopping doctors' selling activities:1. to curb doctors' selling activities in consulting room; 2. to formulate health law and regulations, standardize medical behavior; 3. to deepen health reformation, improve investment mechanism.

Traditionally the cultivation mechanisms of pathological postgraduates can not fully adapt to the demand of research and society in China,to some extent,which impedes the development of pathology.Combining our practical conditions with overseas experiences,we try to make the beneficial thinking and adjustment on the existing cultivation mechanisms.

Objective To study the indications of endoscopic treatment for carpal tunnel syndrome(CTS).Methods From July 2004 to September 2007,21 patients(24 wrists) with CTS received endoscopic treatment in our hospital.Under local anesthesia,an 1-cm incision was made at the level of the proximal transverse wrist crease ulnar to the palmaris longus tendon.A special cannula was inserted into the carpal tunnel,and then the transverse carpal ligment was cut and the median nerve was decompressed.All the patients were re-examined in 1,2,3,and 5 months postoperation.Results According to the criteria of Kelly,11 cases achieved excellent outcomes in 5 months,meanwhile 6 were good,2(3 wrists) were fair,and 2 were poor.One of the 2 poor cases received a second operation by traditional procedures(nerve release) 7 months after the first surgery,another case were treated by conservative therapy because of sympathetic symptoms.Conclusions ① Endoscopy is the first choice for idiopathic cases,while open surgery should be performed on secondary cases(rheumatic synovitis,fracture deformity,tumar,inflammation,gout,neurodegenerative desease etc.).② The carpal tunnel release should be used for patients with abnormal opponens function of the thumb,as well as advanced cases.③ Routine operation are the first choice for eldly patients but not for the younger ones.

Objective To explore the effect of hypoxia on the in vitro invasion of lung carcinoma cells and its molecular basis. Methods Small cell lung carcinoma cells(H128) were exposed to hypoxia(5%O 2,5%CO 2,90%N 2) or anoxia(95%N 2,5%CO 2)condition for 48 hours. The invasive ability of the cancer cells was assayed with HABM-HEM model. The expression of E-cadherin and ? 1-integrin on the cells was also assayed by flow cytometry. Results Compared with normoxia group, the invasive ability of the cancer cells increased, the expression of E-cadherin decreased, and the expression of ? 1-integrin increased in hypoxia group. In anoxia group, the invasive ability and the expression of E-cadherin and ? 1-integrin all decreased compared with normoxia group. Conclusions Moderate hypoxia can down-regulate the expression of E-cadherin, up-regulate the expression of ? 1-integrin, and increase the invasion of carcinoma cells. But serious hypoxia can decrease the expression of adhesive molecules and the invasion of the cancer cells.

The hypercholesterolemia model was established by feeding mice on hypercholester-ol diet. FGS was administered to the hypercholesterolemia mice at the dose of 250,750 and 1500mg ? kg-1 ?d-1, respectively. On the 10,20,30 and 40th day, the serum cholesterol was determined. The results were as follows: 40th day the concentration of TC(Ⅰ,Ⅱ,Ⅲ) was 37. 6,54. 2 and 66. 2mg ?dL-1 lower than that of the control group; and the cocentration of LDL-C was 47. 6,86. 6 and 94. 4mg ?dL-1 lower than that of the control group; while the concentration of HDL-C was 16. 1,38. 2 and 36. 7mg?dL-1 higher than that of the control group. It was proved that FGS was an effective serum cholesterol regulator.

0.05). The production of TNF-? in LPS group was higher than that in control group (61 ng/L vs 156 ng/L, q=5.12, P

AIM:To observe the changes of nuclear factor-?B (NF-?B) activity and inducible nitric oxide synthase (iNOS) expression in hypoxic pulmonary hypertension(HPH). METHODS:The rat model of HPH was used. The NF-?B activity and iNOS expression in lung tissue were determined by immunohistochemistry(IHC), in situ hybridization (ISH), RT-PCR and Western blot.RESULTS:ISH showed that iNOS mRNA expression in intraacinar pulmonary arteriole (IAPA) in H28 d group(hypoxic treatment for 28 days) was stronger than that in normal group, H5d group and H14 d group. RT-PCR showed that the iNOS mRNA in H28 group was 2.1 times, 1.9 times and 1.8 times higher than that in normal group, H5d group and H14 d group, respectively. The nucleic anti-NF-?B stain was observed in H28 d group, which was significantly stronger, but the I-?B amount was 2.8 times, 2.7 times and 2.5 times lower than that in normal group, H5d group and H14 d group, respectively. CONCLUSION: The activity of NF-?B was correlated with the hypoxic pulmonary vessel structural remodeling and iNOS expression.

AIM: To investigate the expression of phosphatidylinositol 3-kinase (PI-3K) during the proliferation of the hypoxic pulmonary arterial smooth muscle cells(PASMC). METHODS: The cultured PASMC was divided into two groups: serum-free medium (SFM) group and 48 hours hypoxia (H48h) group. Immunohistochmistry(IHC) and Flowcytometer(FCM) were used to detect the cultured PASMC. RESULTS: The positive expression of PI-3K p110 existed in both cultured PASMC groups. The staining intensity in H48h group (0 1891?0 0301) was significantly stronger than that in SFM group (0 1025?0 0164, P
