Selenium is one of the essential trace elements for man. A close relationship between the selenium levels and diseases of human beings exists. The determination of selenium may provide a valuable index in prevention and treatment of human diseases. 3 quantitative control diagrams are used as means of method examination in determination fo selenium. The role of control diagram in determination procedure is discussed.

An increasing number of young patients who suffer from endometrial carcinoma (atypical hyperplasia of endometrium) succeed in childbirth.However,some young patients have to receive surgery due to resistance and prognosis and so on.Here we make a brief revicw of the failure-related issues and subsequent treatment of young patients of endometrial carcinomas (atypical hyperplasia of endometrium) who fail in conservative treatments.

Objective To investigate the clinical characteristics, pathological and biochemical featur es of paraneoplastic syndromes (PNS) of hepatocellular carcinoma (HCC). Methods The clinical data of 624 HCC patients (the ratio of male to female 5.3∶1) ident ified by pathology were retrospectively reviewed. Results Among the patients with HCC, 32.2% (201/624) had PNS, the ratio of male to femal e was 4.6∶1. PNS mainly manifested as six clinical abnormalities: hyperchol esterol emia (15.9%), hypoglycemia(8.2%), thrombocytosis(7.7%), leucocytosis(4.8%), eryt hrocytosis(3.4%), hypercalcemia (1.0%). The carcinoma of PNS originated in multi si tes, they mainly located at the right lobe of liver, whilst 47.5% of patients wi th PNS were involved in two lobes. The level of ?-glutamyltranspeptidase in PN S was statistically higher than that free of PNS controls (261.2?224.0 vs. 165 .8?152.2, P

Methods In medical genetics teaching,set the clinical Class 1 grade 2007 to the control group,using traditional pedagogy,set the clinical Class 2 grade 2007 to the experimental group,using PBL and CBS pedagogy. Results Final exam results showed that the experimental group's average scores were significantly higher than control group(P

Objective To study the effect mechanism of anticancer synergic (KangAiZengXiao,KAZX) decoction on gastric cancer in immunologic deficit rats with implanted tumor. Methods Forty rats were divided into normal control group(n=10), model group(n=15) and KAZX treating group(n=15). Model group and KAZX group were subcutaneously injected axillary the left upper limb with 0 5ml gastri cancer cells,MGC-803 cell(1?10 7/ml) after irradiated by 60 Co(dose:10Gy). Then the three groups were treated with KAZX decoction or distilled water every day, respectively. After three weeks, the rats were sacrificed,and blood WBC, the weight of spleen, activity of NK cell and transformation efficiency of lymphocyte were also detected.Results The rate of loaded tumor in KAZX group was significantly lower than in model group(20% vs 66 7%,P

Objective:To investigate the effects of YiqiWenyangHuoxue decoction on NF-?B in the myocardial remodeling of rat with chronic heart failure(CHF).Methods:Heart failure medel was established with ? ushing dose isoproterenol in rats and cardiac hypertrophy with angiotensin Ⅱ(Ang Ⅱ) stimulation 48h in myocardial cell.The model rats and cardiocytes with CHF were treated with YiqiWenyangHuoxue decoction,then cardiac index in model rats was measured;TNF-?,IL-18 were determined by ELISA;NF-?B mRNA evaluated with RT-PCR,and protein by Western-blot.Results:Compared with the control group,TNF-?,IL-18 concentration were significantly higher,as well as NF-?B mRNA and protein levels not only in myocardial tissues but also in cardiocytes of CHF groups.But those can be attenuated by YiqiWenyangHuoxue decoction.Conclusions:NF-?B plays important roles in the myocardial remodeling of CHF;and YiqiWenyangHuoxue decoction may reverse the myocardial remodeling through blockingNF-?B.

Objective To observe the expressions of insulin-like growth factors(IGFs) and proliferating cell nuclear antigen(PCNA) in various kinds of liver tissues,we discussd the relationship among IGFs,PCNA and HBV-DNA integration in the process of hepatocarcinogenesis,provide some theoretical basis for the mechanism of hepatocarcinogenesis and clinical diagnosis and therapy of HCC.Methods 32 cases of HCC,32 cases of paracancerous liver tissues(PLT),12 cases of chronic active hepatitis(CAH),10 cases of fetal liver tissues(FLT) and 8 cases of normal adult liver tissues(NALT) were collected.Southern hybridization was used to detect HBV-DNA integration in various kinds of liver tissues.Then a colloid gold immunoelectron microscopic technique was used to make a systematic study on the expression and ultrastructural location of IGFs and PCNA in different liver tissues.Results The HBV-DNA integration was positively existed in 81 3%(26/32) of HCC and PLT,and 83 3%(10/12) in CAH,but the integration in NALT and FLT was no existed.PCNA was expressed by 87 5%(28/32) of HCC and 84 4%(27/32) of PLT,respectively.The postive rates of IGF-Ⅰ and IGF-ⅠR expressed by HCC were 40 6%(13/32) and 56 3%(18/32),those of IGF-Ⅰand IGF-ⅠR expressed by PLT were 50 0%(16/32) and 65 6%(21/32),respectively.The positive rates of IGF-Ⅱ and IGF-Ⅱ receptor(IGF-ⅡR) expressed by HCC were both 78 1%(25/32),and those expressed by PLT were both 81 3%(26/32).In the integration group of HBV-DNA had higher positive rates of IGF-Ⅱ and IGF-ⅡR,which were expressed by the HCC and PLT groups,than that of non-integration group of HBV-DNA(P

Objective To observe the blind area in routine gastric lavage and evaluate its significance. Methods Each of 10 healthy volunteers drank 60 ml water containing 185 MBq 99mTc. Images of mouth, esophagus and stomach of all subjects were collected from anterior position with gamma camera, and intraoral and intraesophageal radiocounts were monitored with " Region of Interesting" technique at 0, 0.5, 1,2,3 and 4 hours. Ratios of the counts at subsequent time points vs the count of 0 hour were calculated. For other 13 volunteers, 100 ml, 200 ml, 300 ml and 400 ml normal saline containing 25% compound meglucamine diatrizoate were drunk and injected into stomachs through stomach tube respectively. After that, X-ray chest films were taken at the dorsal and left lateral decubitus positions to observe the oral and e-sophageal developments. Results The images of mouths and esophagus of 10 subjects could be identified more than 4 hours after the administration of 99mTc. The ratios of oral counts and esophageal counts at 0. 5 ,1, 2, 3 and 4 hrs were 30. 7% , 10. 5% , 6. 3% , 4. 7% , 3. 7% , and 18. 6% , 4. 4% , 3. 5% , 3. 0% ,2. 7% respectively. The ratios of both oral and esophageal counts were 49. 3% , 14. 9% , 9. 8% , 7. 7% and 6.4%. When the liquid was drunk, full oral and esophageal developments could be identified. While the liquid was injected through the tube, no development was found. Conclusions Liquid drug may remain in mouth and esophagus for a long period of time after administration. Routine gastric lavage through nasogastric tube can not clean the oral and esophageal drug residues. There are oral and esophageal blind areas when routine gastric lavage is employed.

To explore the mechanism of Jianpi(splenic tonic) and Shugan(dispersing the stagnated liver-qi) prescription regulating immunity by testing the expression of the differentiation signaling transduction protein,calcineurin.Methods We prepared the Sijunzitang and Chaihushugansan prescription serum,take the Ova as antigen induction and B cell as presenting cell,intervened culturing the CD 4 +T cells for 24 hours, and then examine the expression of calcineurin by RT-PCR,Western-blotting.Results The expression of calcineurin was increased in the stimulated Th cells, and the Sijunzitang and Chaihushugansan prescription serum can reduce it significantly,the Chaihushugansan also improved the expression deficit of calcineurin.Conclusions Jianpi and Shugan prescription can regulate the balance of immunity through affecting the expression of signaling transduction proteins at the Th activation and differentiation stage,The regulating the flow of qi prescription is superiority to supplementing qi one.in treatment of the Th2-mediated autoimmune disease.

Objective To investigate change of Th 1/Th 2 Cytokines in the rats with spleen deficiency syndrome and effect of decoction of SiJunZi on it. Methods The contents of IL-4 and IFN-? in the T cells of the rats with spleen deficiency syndrome before and after treatment of decoction of SiJunZi and powder of ChaiHuShuGan were detected by ELISA. Results Compared with normal group, the content of IFN-? decreased (P0 05). After treated with powder of ChaiHuShuGan, the levels of IL-4 and IFN-? did not obviously change compared with normal group (P
