Objective　To evaluate the value of CT virtual gastroscopy (CTVE) in clinical applications. Methods　52 patients (65 foci of stomach) were examined by CTVE combined with 2D CT, gastrointestinal series (GI) and fibric gastroscopy (FG). The accurate ratio in quantitative, locating, qualitative and staging diagnoses was compared. Results　CTVE demonstrated the diameter of 0.3 cm foci in stomach. The accurate ratio in quantitative, locating and qualitative diagnoses with combination of CT and CTVE was higher than that of GI (P<0.001 ) but lower that of FG (P>0.05); In staging, CTVE was better than GI and FG. Conclusion　CTVE is a complementary gastric examination, which can replace GI in the diagnosis of common physical gastrical diseases.

Objective To investigate the effect of castration on heart function in male rabbits postinfarction congestive heart failure model. Methods 32 male 4-5 months old New Zealand rabbits were randomly assigned to ligation of first branch of left coronary artery or sham operation (sham group, n=8). 3 weeks later 20 survived MI model rabbits were randomly subjected to castration (castration group, n=10) or sham operation (MI group, n=10). Serum FT, DHEAS levels and LVEF were checked at week 0, 3 and 15. Heart diameter and left ventricular wall thickness were measured at week 15. Results The serum FT and DHEAS levels decreased significantly at week 3. In MI group and castration group serum androgen level was lower and heart weight, ventricular diameters, ventricular wall thickness corrected by body weight were higher than that in sham group at week 15. The androgen level and body weight of castration group were lower than that in MI group. But LVEF in castration group was not higher than MI group. Conclusion There was no benefit effect of castration on heart function in male rabbits postinfarction congestive heart failure model.

Objective To evaluate the relationship between the serum free IGF-1 level and the severity and prognosis in patients with chronic severe hepatitis. Methods Serum free IGF-1 was assessed by ELISA in 44 patients with chronic severe hepatitis, 43 chronic viral hepatitis, 46 liver cirrhosis. At the same time the liver function, prothrombin activity and cholinesterase were also determined. Results Serum free IGF-1 in patients with chronic severe hepatitis, liver cirrhosis and chronic viral hepatitis was 0.24?0.15,0.33?0.17 and 1.06?0.70 (ng/ml), respectively. IGF-1 was significantly decreased in patients with chronic severe hepatitis and liver cirrhosis. IGF-1 level in patients with chronic severe hepatitis at early, middle and advanced stages was 0.28?0.07, 0.27?0.19 and 0.16?0.06 (ng/ml), respectively. The reduction in the value showed a positive correlation with different stages of chronic severe hepatitis. Patients with chronic severe hepatitis having a serum free IGF-1 below 0.2ng/ml had a higher mortality, and those with the value above 0.35ng/ml had a better chance to survive during the follow-up period. There was a significant positive correlation between serum free IGF-1 and prothrombin activity. Conclusion Serum free IGF-1 was decreased in the patients with chronic severe hepatitis. The clinical observation suggested that the serum free IGF-1 might be an important prognostic indicator in patients with chronic severs hepatitis.

Objective To study the value of neoadjuvant chemotherapy in the treatment of cervical carcinoma. MethodsA clinical prospective study was carried out from Jan.1997 to Dec.2003,118 patients with cervical carcinoma were given two cycles of combined chemotherapy before operation(neoadjuvant chemotherapy group,group A).102 patients accepted surgery alone in our hospital from Jan.1997 to Dec.2003 were chosen as the comparison group(group B).Survival rate and complications were observed and analysed. Results5 year survival rate in group A was significantly higher than that in group B(P＜0.01),The 5 year survival rate was significantly higher in group A than in group B,despite of different pathological types,with or without radiochemotherapy(P＜0.05).The recurrent rate was lower in group A than that in group B,which show significant difference in the 5 year recurrent rate(P＜0.05). ConclusionNeoadjuvant chemotherapy is an effective method for the treatment of cervical carcinoma in early stage.Because of satisfactory short-term control rate,excision rate,long-term survival rate and low recurrent and metastatic rate,neoadjuvant chemotherapy is worth popularizing in clinical treatment.

AIM: To observe the enhanced green fluorescent protein (EGFP) gene expression and cytotoxicity in human adipose derived adult stem cells (hADSCs) by pEGFP-N1, Ad5-EGFP and rAAV-2/1-EGFP, and investigate the suitable gene-transferred vehicle. METHODS: The experiment was conducted at Chinese National Human Genome Center and the Third Hospital of Peking University from January to July 2006. ①After the patients and their relative were informed consent, the subcutaneous adipose tissue was obtained from the patients undergoing routine total hip joint replacement in Department of Orthopaedics, Third Hospital of Peking University. pEGFP-N1 was provided by Clotech Company, Ad5-EGFP and rAAV-2/1-EGFP by Vector Gene Technology Company. ②hADSCs were cultured in vitro after isolated from the adipose tissue after dissected and digested with type I collagenase. ③hADSCs of passage 3 were infected with pEGFP-N1, Ad5-EGFP and rAAV-2/1-EGFP and the EGFP expression and the cell toxicity were observed. ④Twenty-four hours after being transfected, 5?104 cells were reseeded in a 24-well plate and the solution was changed three times every week. The growth curves of each group were drawn. Normal non-transfected cells served as control. The influence of different transfection ways on the growth of hADSCs was observed. RESULTS: ①Comparison of transfected efficiency with different ways: pEGFP-N1 transfection showed a higher cytotoxicity and lower efficiency of 10.5%; Ad5-EGFP could efficiently transfect hADSCs (multiplicity of infection=5?102, 82.5%); when MOI was 0.05); however, the growth capability of hADSCs was decreased significantly in the pEGFP-N1 transfection group compared with the control, and the differences were significant at day 3-10 after transfection (P

Objective:To investigate the efficacy of lanthanum carbonate versus calcium acetate in the treatment of hyperphosphatemia in patients receiving maintenance hemodialysis. Methods:A total of 202 patients with chronic renal failure who received maintenance hemodialysis in Department of Nephrology, Yiwu Central Hospital from March 2016 to January 2017 were included in this study. These patients were on dialysis for ≥ 6 months with blood phosphorus level > 1.78 mmol/L before dialysis. They were randomly divided into the lanthanum carbonate ( n = 100) and calcium acetate ( n =102) groups. Two patients in the lanthanum carbonate group withdrew from the study due to intolerance of vomiting. All patients were treated for 9 months. During the study period, low calcium dialysate was rationally used, and strict dietary phosphate restriction was applied. The changes in serum phosphorus, calcium and parathyroid hormone contents before and after treatment were compared between the two groups, and they were compared between before and after treatment in each group. Results:During the treatment, the average dose of phosphate binder was 1 500 mg/d in the lanthanum carbonate group and 3 335 mg/d in the calcium acetate group. There were no significant differences in general demographic data and biochemical indexes between the two groups (both P > 0.05). No significant differences in dietary phosphorus content and dialysate calcium concentration were observed between the two groups (both P > 0.05). In the calcium acetate group, blood phosphorus content decreased from (2.12 ± 0.35) mmol/L before treatment to (1.55 ± 0.24) mmol/L after treatment ( t = 13.43, P < 0.01). In the lanthanum carbonate group, blood phosphorus content decreased from (2.14 ± 0.3) mmol/L before treatment to (1.45 ± 0.17) mmol/L after treatment ( t = 20.01, P < 0.01). In the lanthanum carbonate group, the difference in blood phosphorus content between before and after treatment was (0.69 ± 0.29) mmol/L, which was significantly higher than that in the calcium acetate group [(0.57 ± 0.37) mmol/L, t = 2.553, P < 0.01]. Hypercalcemia did not occur in both groups, and there were no significant differences in carotid intima thickening and presence of calcified plaque between the two groups (both P > 0.05). Conclusion:Under the premise of effectively implementing rational low calcium dialysate use and strict dietary phosphate restriction, both calcium acetate and lanthanum carbonate can effectively reduce the blood phosphorus level in patients undergoing maintenance hemodialysis. Lanthanum carbonate has better effect in reducing serum phosphorus level than calcium acetate, but it is likely to produce gastrointestinal reactions. Neither treatment method bears the risk of hypercalcemia.
