Objective To explore the expression of Bcl-2 and calretinin(CR)in enteric ganglion cells in different developmental conditions and its significance.Methods The immunohistochemical staining was carried out to detect the expression of Bcl-2 and CR in enteric ganglion cells at different intestinal segments from tissue samples of 40 hirschsprung disease(HD) cases(age,26 d to 12 years old),10 Hirschsprung's allied disease(HAD) cases and 10 normal controls.Results In immature ganglion cells,there was a strong expression of Bcl-2,and no positive to or poor expression of CR.In mature ganglion cells,there was a strong expression of CR but no positive Bcl-2 staining.Conclusion The specific expression of Bcl-2 and CR may play an essential role in judging if the ganglion cells are mature.Bcl-2 might be of importance in the maintenance and restore of the fuction of enteric immature ganglion cells.

Hospital information system is indispensable for hospital management,and its evaluation indexes system serves as the cornerstone for evaluation of hospital informationization.Basic evaluation indexes for hospital informationization were earmarked objectively as well as quantitatively and qualitatively,based on expert opinions.The evaluation indexes of hospital informationization consists of six dimensions and 23 secondary indexes.The paper described in detail the data makeup for reference of building the evaluation indexes system of hospital informationization.

Objective To study the current situation of diagnosis and treatment of rudimentary uterine horn pregnancy through 4-cases report. Methods We made a clinical study of 4 cases of rudimentary uterine horn pregnancy admitted to our hospital between 1995 and 2005. Results Three patients had been undergone artificial abortion before they were admitted to our hospital. All the patients were asymptomatic. Ultrasonography was made in 3 cases. Two cases were diagnosed as rudimentary uterine horn pregnancy. Three patients were cured with surgery. Conclusions Rudimentary uterine horn pregnancy is rare and with atypical clinical manifestation in the first trimester. Although diagnosis before surgery is difficult, ultrasonography and MRI make a great role. Surgery is the most important therapeutic method.

A method for the determination of Pt、Pd、Ru、Rh 、Ir and Au in geological samples was studied. The sample was fused by sodium pe roxide and determined by a double focusing high resolution inductively coupled p lasma mass spectrometer “ELEMENT” after the separation and enrichment by co-precipitation with Te. Detection limit of the method was between 1～9ng/g and the recovery was ＞90%. Our analytical results for some domestic or interna tional reference materials were in agreement with the certified values.

Objective To study the role of Schwann cells apoptosis in the pathogenesis of experimental autoimmune neuritis(EAN) in TNF receptor Ⅰ knock out(TNFR Ⅰ-/-)mice.Methods For induction of EAN,TNFRⅠ-/- and wild type C57BL/6 mice were immunized by subcutaneous injection into the back with the peripheral nerve P0 protein peptide 180-199;clinical scores of EAN were assessed and scored immediately before immunization(day 0) and thereafter every other day until day 46 post immunization(p.i.).On day 22 p.i.,Schwann cells were collected from the two groups and cultivated in vitro.The expressions of Fas and Annexin-Ⅴ(Annexin-Ⅴ+/PI-)on Schwann cells from TNFRⅠ-/-and wild type EAN were detected by flow cytometry.Results More light clinical signs of EAN were observed in the TNFRⅠ-/-mice(1.50?0.19) than in wild type mice(1.90?0.16);the percentage of Fas expression on Schwann cells was significantly decreased in TNFRⅠ-/-mice(88.03%?1.40%)as compared with wild type mice(94.70%?1.53%)(P

Objective To investigate the influence of rosuvastatin on inflammatory factors and immune func-tion in chronic obstructive pulmonary disease(COPD)with pulmonary heart disease.Methods 80 COPD patients with pulmonary heart disease were randomly divided into two groups,40 cases in each group.The control group was treated with conventional medicine comprehensive treatment,the observation group was given rosuvastatin based on the control group.The inflammatory cytokines (TNF -α,IL -1 and hs -CRP)changes,immunoglobulin IgM,IgG and IgA changes situation,and heart,lung function changes related indicators were compared between the two groups before and after the treatment.Results After treatment,the TNF -α,IL -1 and hs CRP levels of the observation group were significantly lower than those before treatment(t =145.5,35.35,57.5,all P <0.05)and those of the control group(t =160.75,11.45,32.99,all P <0.05).After treatment,the IgM,IgG and IgA levels of the observa-tion group were significantly lower than those before treatment (t =4.89 of 18.29,3.42,all P <0.05)and those of the control group (t =2.55 9.67,2.342,all P <0.05 ).After treatment,the FEV1 ,FEV1 /FVC and LVEF of the observation group were significantly higher than those before treatment(t =40.44 33.64,33.79,all P <0.05),while the PAP level was significantly lower than that before treatment (t =24.12,P <0.05),and the FEV1 ,FEV1 /FVC and LVEF of the observation group were significantly higher than those of the control group after treatment(t =16.30, 15.82,18.72,all P <0.05),while the PAP level was significantly lower than that of the control group after treatment (t =13.43,P <0.05).Conclusion Combined rosuvastatin therapy for COPD patients with pulmonary heart disease can effectively reduce body inflammatory response,improve immune function and myocardial contractility,so it can promote functional recovery of heart and lung in patients.

Objective Study the effect of transvaginal bitths in term pregnant women with less amniotic fluid B-mode ultrasonography suggested on neonatal and find the correct approach. Methods The maternity outcome of 166 pregnant women with less amniotic B-mode ultrasonography suggested fluid was compared with that of 187 term pregnant women with normal amniotic fluid.Results There was no significant difference on severe meconium stained amniotic fluid and the rate of neonatal asphyxin between two groups.Conclusion Transvaginal biths can be tried in term pregnant women with less amniotic fluid B-mode ultrasonography suggested under the intensive care.

During the treatment of pain syndrome,professor JIANG Jian’ clinical experience by using later generation's prescriptions was extraordinary,deserved to learn an reference.

A simple thin layer chromatography ultraviolet densitometric method has been established for the separation and quantitative determination of Puerarin in plasma. Using ethyl acetate : metha-nol: water : toluene : absolute alcohol ( 100 : 15.5: 13.5: 2 :13.5 V/V ) as the developing system, 5?l supernatant of the sample extracts were spotted on high performance sillica gel G glass plates and developed. The separeted spots were scanned using Shimadzu CS-910 TLC scanner, the results were calculated by the areas of spots with Rf 0.47. The mininum detectable quantity of Puerarin was 7.5ng/spot. The plasma concentration-time curve of Puerarin in rabbits after single iv 30mg/kg was best fitted to a two- compartments open model. The T1/2? , T1/2? (3 were 5.7, 27.5 min respectively. This showed that Puerarin is distributed and eliminated in a fairly rapid rate in rabbits.
