Objective To evaluate the efficacy of transcatheter arterial chemoembolization (TACE) combined with hypofractionated 3 dimensional conformal radiotherapy for hepatocellular carcinoma (HCC). Methods During May 1998 and Dec. 1999, 81 unresectable HCC patients were divided into two groups. Forty one patients in group A were treated with TACE and hypofractionated 3 dimensional conformal radiotherapy and 40 patients in group B were treated with TACE alone. Acute effects were analyzed and survival rates were assessed from the date of the beginning of treatment using the Kaplan Meier method. The survival rates of two groups were compared using Log rank. The Cox proportional hazards model was used to analyze the prognostic factors in group A. Results The objective response rate in group A was higher than that in group B (85.4% vs. 65.0% , P

Objective To investigate the molecular epidemiology as well as the subtypes of HIV in intravenous drug abusers, which can help pursue the source of infection in Zhejiang province and predict the epidemic strain in the future. Methods Such as ELISA, Western blot, nest PCR, DNA and sequencing technologies were used to analyze HIV subtypes of 15 strains isolated from intravenous drug abusers(IVDU) from Xinjiang autonomous region. Results All of the 15 IVDUs were infected with HIV 1, 2 of which were infected by subtype E and the others were infected by subtype C. Conclusions Subtype C is main HIV subtype infecting IVDUs. The epidemic subtype may have changed in China.

Objective To investigate the expressions of nitric oxide synthase (NOS) protein and mRNA in the lung of rats with hepatopulmonary syndrome. Methods Male Sprague-Dawley rats were divided into four groups: sham operation (SO), intrahepatic portal hypertension (IHPH), prehepatic portal hypertension (PHPH) and portasymstimic shunt (PCS). Two weeks after preparation of rat models, the following measurements were performed: arterial blood gas analysis; the concentrations of NO in lungs; in situ hybridization of ecNOS and iNOS mRNA expressions in lung tissue sections with digoxin-labeled ecNOS and iNOS oligonucleotide probes; expressions of ecNOS and iNOS proteins by immunohistochemisty; image and semiquantitative analysis of the expressions of ecNOS, iNOS and their mRNA. Results PaO_ 2 was (73.85?6.51) mmHg in IHPH rats, significantly lower than that in PHPH, PCS and SO rats97.39? 1.33, 95.23?2.22 and (99.05?0.75)mmHg, respectively.The level of lung NO of IHPH was(19.78?5.33)?mol per gram of protein,much higher than that of PHPH, PCS and SO 13.21?3.99,13.89?3.16 and (8.71?1.68)?mol per gram of protein,respectively. In capillary endothelia, positive expressions of ecNOS mRNA and ecNOS protein in IHPH(4.96?0.82,4.11?0.28) were significantly higher than those of PHPH (1.81? 0.39, 1.63?0.18), PCS (1.88?0.53,1.83?0.16)and SO(1.19?0.32,0.98?0.20). Conclusion The expressions of NOS protein and mRNA in the lung of rats with hepatopulmonary syndrome were increased, and the level of lung NO was elevated, which seems to play an important role in the pathogenesis of hepatopulmonary syndrome.

Objective To investigate the peripheral blood Th17 and CD4 + CD25 + regulatory T cell levels and their correlations in patients with primary hepatocellular carcinoma (PHC).Methods Peripheral blood samples were collected from 30 PHC patients and 25 healthy controls in the First Affiliated Hospital of Zhejiang University from June 2008 to May 2009.Mononuclear cells were isolated and the Th17 and CD4 + CD25 + regulatory T cells were detected by flow cytometry and compared between patients and controls by t test.Spearman test was performed to analyze the correlation of Th17 with CD4 + CD25 +regulatory T cell concentrations.Results The levels of Th17 and CD4 + CD25 + regulatory T cells in peripheral blood in healthy controls were (2.10 ± 0.87) % and (7.10 ± 2.32) % ; while those in PHC patients were (3.38±1.68)% and (11.78±5.62)% (t=3.640 and 4.162,P<0.01).The level of Th17 cells was positively associated with that of CD4 + CD25 + regulatory T cells in PHC patients (r =0.821,P <0.01).Conclusion The levels of Th17 and CD4 + CD25 + regulatory T cells in peripheral blood are high in PHC patients and positively correlated with each other,which indicates that CD4 + CD25 + regulatory T cells may contribute to the disease progression and pathogenesis of carcinoma through inducing Th17 cells differentiation.

Objective To study the methods and outcome of 71 patients with Parkinson's disease treated with microelectrode-guided stereotactic pallidotomy and thalamotomy. Method Pallidal and thalamal target sites are chosen by supervision of microelectrode recording technique in 71 patients with Parkinson's disease. The UPDRS motor score was used to evaluate the outcomes 12 weeks before and after operation Result After 12 months follow-up, tremor disappeared completely or nearly completely in 12 patients who underwent unilateral and l bilateral ventrolateral thalamotomy. Dramatic improvement of tremor, rigidity, bradykinesia were observed in 57 patients underwent posteroventral pallidotomy,including 6 underwent bilateral posteroventral pallidotomy. Intracerebral hemorrhage was observed in l patient. Conclusion Microelectrode-guided stereotactic pallidotomy and thalamotomy are effective in treatmenting Parkinson's disease, but with serious complications

Objective To determine the iodine content of common foods in different geographical areas (coastal city,coastal rural area,mountainous city and rural area) in Fujian Province and provide basic data for evaluation of dietary iodine intake.Methods In 2010,based on the types of food of the total diet study,one food sample(consumption rate is greater than 1%) was collected in coastal city(Taijiang),coastal rural area(Xiang'an),mountainous city (Sanyuan) and rural area(Mingxi).These foods including cereal,beans,potato,meat,eggs,milk,aquatic products,vegetables,fruits,sugar,beverages,liquor and seasoning,and so on 184 kinds of common foods.The iodine content of these food was tested by As (Ⅲ)-Ce4+ catalytic spectrophotometry.Results Among the 184 kinds of food tested,164 were not indicated food iodine content in the Chinese Food Composition Tables (2004).The iodine content of common food in Fujian Province in descending order were salt (30 000 μg/kg),aquatic products(341.4 μg/kg),eggs(255.9 μg/kg),dairy(106.7 μg/kg),meat(103.2 μg/kg),cereals (40.7 μg/kg),vegetables(30.7 μg/kg),beans(12.9 μg/kg),sugar(8.5 μg/kg),fruits(6.7 μg/kg),potatoes(2.4 μg/kg) and alcohol(2.1 μg/kg).The iodine content of kelp and laver was the highest in all the food,which was 314 780.1,176 956.5 μg/kg,respectively.The iodine content of food from animal(241.4 μg/kg) was much higher than that of the food from plant(25.4 μg/kg).The iodine content of common cereals,potatoes,beans,sea algae,meat,eggs and aquatic products was compared in the four areas,and the difference was not statistically significant (M =135.5,20.0,42.0,16.0,54.0,4.0,x2 =1.4,all P > 0.05).The iodine content of vegetables and fruits was compared,and the difference was statistically significant (x2 =8.5,M =204.5,all P < 0.05).Conclusion The iodine content of different foods is different.
