Objective: To observe the clinical efficacy of thunder-fire moxibustion for hypomenorrhea after induced abortion. Methods: A total of 74 patients with hypomenorrhea after induced abortion were randomized into two groups, with 37 cases in each group. The control group was treated with conventional hormone sequential therapy, and the observation group was treated with thunder-fire moxibustion. The course of treatment was 3 menstrual cycles. The traditional Chinese medicine (TCM) symptom scores, menstrual volume, endometrial thickness and the sex hormone levels were observed before and after treatment. The clinical efficacy was compared after treatment. Results: The total effective rate in the observation group and the control group was 91.4％ and 73.5％, respectively, and the difference between the two groups was statistically significant (P<0.05). After treatment, the TCM symptom scores in both groups decreased significantly (all P<0.05), and the scores in the observation group were lower than those in the control group (P<0.05). The menstrual volume, endometrial thickness and each sex hormone level of the patients in both groups were significantly improved after treatment (all P<0.05), and the improvements in the observation group were more significant than those in the control group (all P<0.05). Conclusion: Thunder-fire moxibustion can significantly improve the clinical symptoms of patients with hypomenorrhea after induced abortion; it can increase menstrual volume and endometrial thickness, and regulate the sex hormone levels, producing a better curative effect than the conventional hormone sequential therapy.

Objective To test whether multiplex ligation-dependent probe amplification(MLPA)could be used for the prenatal detection of the most common aneuploidies of chromosomes 13,18,21,X,and Y.Methods 34 cases including 22 blood samples(12 with trisomy 21,1 with monosomy X,one male witll extra Y and 8 healthy persons),4 cord blood samples with Down syndrome and 8 amniotic fluid samples ( 1 with trisomy 21 and 7 normal fetuses)were recruited into this study.All samples were confirmed by karvotype analysis. DNA was extracted from blood and amniotic lysate was incubated with proteinase K.MLPA was used to determine the relative copy numbers.Results The resuhs were available within 48 h and were concordant with karyotype analysis in all but one case of amniotic fluid that was suggested to be triploid sample 69,XXY by MLPA or contaminated by maternal blood.This sample actually was found containing a number of red blood cells after centfifugation in test. In total,the concordance rate with clinical characteristics was 97.1%.The Ratio values of 13,18,21,X in normal samples were approaching 1.0 except chromosome Y having slightly higher variation in relative copy number.The difference of ratio means between the normal and trisomy 21 samples was statistically significant by one-way ANOVA(F=298.906.P=0.000).Conclusion Computer assisted MLPA with high sensitivity is a rapid,simple,automatic and reliable method for detection of common chromosomal aneuploidies.

Objective To investigate the effect of calcium antagonist verapamil on the function of rat?- cells and tolbutamide (D860)-induced insulin release.Methods Insulin released from isolated islets were measured in control,verapamil,D860,and verapamil+D860 groups.Furthermore,intravenous glucose tolerance test (IVGTT) was conducted in acute experiments treated with verapamil and D860 respectively to assess?-cell function in rats with the same allocation as in vitro.Another IVGTT was performed in the end of 4 weeks' treatment.The insulin contents in pancreas were assayed and pancreas islets morphology were observed with immunohistochemistry.Results Verapamil could inhibit insulin release from isolated islets.Verapamil group was [(1.244?0.082)ng?ml~(-1)?islet~(-1)]and control group (2.623?0.226) ng?ml~(-1)?islet~(-1)(P0.05).Also,similar results were obtained in normal rats during acute experiments and verapamil reduce the hypoglycemic effect promoted by D860. However,above results were not observed in the end of 4 weeks experiments,and no difference for insulin content and morphological change in islets was found among four groups.Conclusion Treatment of verapamil chronically does not impair islet function and interfere with the hypoglycemic effect of D860 in rats .

Objective To compare the diagnostic value of renal ultrasound scan (RUS) and 99Tcmdimercaptosuccinic acid (DMSA) renal scintigraphy in children with acute pyelonephritis (APN). Methods In all, 165 children with initial clinical diagnosis of APN, aged from 1.5 months to 11 yrs ( median 20 months), were included in the study, all of which were examined with RUS and DMSA renal scientigraphy. The diagnosis with DMSA renal scientigraphy results was taken as the standard reference to evaluate the diagnostic sensitivity and specificity of RUS. Results Of 99 out of all 330 kidneys that were found abnormal on DMSA renal scientigraphy, 31 were abnormal on RUS. Of the rest normal kidneys on DMSA scans renal scientigraphy, 4 were abnormal on RUS. Thus diagnostic sensitivity of RUS for APN was 31.3%(31/99) and specificity was 98.3% (227/231). Conclusions Although RUS provides with high diagnostic specificity for children with APN, its low sensitivity may underestimate the clinical evaluation of APN.More often than not, 99Tcm-DMSA renal scientigraphy is a clinical necesscity for the definite RUS diagnosis.

ObjectiveTo evaluate the value of serum galactomannan platelia aspergillus kit in the diagnosis and treatment of invasive fungal infection(IFI) patients. MethodsA total of 178 serum samples from 74 high risk patients were collected. ELISA assay was used to detect the level of GM antigen. Refer to domestic IFI diagnostic criteria, 16 patients include the proven cases and probable cases were defined as study group, while 29 patients of improbable cases defined as control group. Fourflod table was founded,by which the sensitivity,specificity,positive predictive value, negative predictive value of this GM test were calculated. Meanwhile, a total of 53 patients received antifungal therapy which divided into GM-positive group(21 patients with I≥0. 5) and GM-negative group(32 patients with I ＜0. 5). The therapeutic effect comparison of two groups was made according to curative effect criterion. ResultsAccording to the certainty level of IFI diagnosis, 1,9,10 and 4 patients were identified as GM positive in proven, probable,possible and improbable IFI groups respectively. The prevalence of GM in these 4 groups was 50％ ,64％ ,34％ and 14％ ,respectively. The sensitivity and specificity of galactomannan ELISA assay were 63％ ,86％ respectively. The positive and negative predictive values were 71％ and 81％ respectively. The diagnose accordance rate was 78％, the Younden index was 0. 49. The efficacy of fluconazole in GM-positive patients was significant lower than in GMnegative patients( x2 =4. 95 ,P ＜0. 05) ,while The efficacy of non-fluconazole drug was superior to that in GM-negative patients( x2 =4. 88,P ＜ 0. 05). After antifungal therapy, the GM value of GM-positive patients decreased significantly( t =2. 13 ,P ＜0. 05). ConclusionThe galactomannan ELISA assay with high specificity, could be helpful in diagnosis and choicing effective anti-fungi drug in clinic.

Objective To investigate the clinical features and distribution of G types of rotavirus diarrhea in infants and children in Suzhou and Maanshan areas.Methods 1267 stool specimens were collected from children under 5 years with acute diarrhea. Enzyme-linked immunosorbant assay (ELISA) and nested polymeras chain reaction (Nested-PCR) were used to detect rotavirus and serotypes.Results In 1267 stool specimens, 378 were detected RV positive, and serotype G was the prevalent type in the two cities with number of 250 and the G3 and G1 types were the most prevalent which accounted for 40%(100/250) and 44.40 % (111/250), respectively. While the G2 ,G4, G9 types and mixed infections were 8,3,3,4 and the un-identified type was 8.40%(21/250). G1 type was the most prevalent in Maanshan are which accounted for 58.54% in all cases,while the G3 type accounted for the most of case(47.85%) in Suzhou area.Conclusions The results indicated that rotavirus was the most important etiologic agent in Maanshan and Suzhou areas,G1 and G3 were the most prevalent types,respectively.

Objective To explore the influence of coal-arsenic exposure on human T cells proliferation and its mechanism.Methods Blood samples colleoted from individuals which lived in arsenism area of coal-burning type and non-arsenism area in Guizhou Province were divided into exposed group(17),mild(35),moderate(38) and severe arsenism group(19)and control group(35)according to Diagnosis Smndard for Endemic Arsenism (WS/T 211-2001).T cell stimulation index wag determined by methyl thiazolyl tetrazolium(MTT)colorimetric method.The intracellular Ca2+ exponential(IECa2+)in peripheral blood mononuclear cell(PBMC)was analyzed by Fho-3/AM dye and flow cytometry.DNA binding activity of actively T cells nuclear factor(NF-AT)in PBMC was evaluated by electrophoretie mobility shift assay(EMSA).Results Concanavalin A(ConA)stimulation decreased the T cells stimulation indexes in exposed group,mild,moderate and severe arsenism groups(1.315±0.962, 1.611±1.224,1.114±0.545,1.289±0.875)compared with control group(2.322±1.241),all the differences being statistically significant(P＜0.01).After stimulated by anti-CD3 monoclonal antibody(McAb),the T cells stimulation index in exposed group,mild,moderate and severe arsenism group(0.997±0.177,1.103±0.291,1.007±0.221, 0.957±0.205) were lower than that of control group(1.842±0.429,P ＜ 0.01 ). IECa2+ of PBMC after treated by anti-CD3 McAb in mild,moderate and severe arsenism group( 110.130±49.637,92.429±31.191,77.640± 35.372) were lower compared with control group(145.986±59.450,P ＜0.01 ). Moreover,IECa2+ in moderat and severe arsenism group were lower than exposed group(121.337±46.410,P ＜ 0.05). DNA binding activity of PBMC NF-AT in mild,moderate and severe arsenism group(1.354±0.446,1.290±0.291,1.159±0.411 ) were lowered than that of control group(1.722±0.291,P ＜ 0.01) and exposed group(1.611±0.294,P ＜ 0.05). Conclusions The coal-arsenic exposure can reduce the human T cells stimulation indexes,IECa2+ in PBMC and the DNA binding activity of NF-AT. It suggest that arsenic may suppress the proliferation ability of human T cells,which may be partly related to the influence of arsenic on T cell receptor(TCR)/CD3 signal transduetion pathway.
