Objective To analyze the clinical features and evaluate outcomes of active pulmonary tuberculosis(TB)patients in floating population.Methods Retrospectively analyzed the clinical data of 68 active pulmonary TB patients in floating population,in comparison with 123 cases of TB patients of local which was treated as control group.Evaluated the outcomes by analyzing the composition of sex and age,tuberculosis type,positive phlegm germ.males and 33 females;so the male to female ratio was 2.73:1,the difference between two groups was statistically significant(x2=3.37,P＜0.05).The age in study group ranged from 18 to 62,the average was(30.23±18.52),and it ranged from 18 to 70 in control group,the average was(46.46±31.50),the difference between two groups was statistically significant(t=25.14,P＜0.05).Among those aged 21 to 30,the incidence in study group was 44.11%(30/68),and in control group it was 24.39%(30/123),the difference between two groups had statistical significance(x2=9.91,P＜0.05).In study group,there were 68 sputum smears,47 of them were positive,and the proportion was 69.11%;In control group,there were 123 sputum smears,70 of them were positive,and the proportion was 56.91%.The difference between two groups had statisticall significance.In study group.there were 22 patients who stopped by themselves accepting treatment,accounting for 34.92%;At same time,in control group,there were 23 patients who stopped by themselves accepting treatment,accounting for 18.67%.The difference of treatment compliance between two groups had statistical significance(x2=6.890,P＜0.05).After 6 months treatment,41 cases were treated in study group,of them 37 cases sputum bacterium turns negative,accounting for 90.24%;the same time 100 cases were treated in control group,of them 92 cases sputum bacterium turns negative,accounting for 92.00%.The difference of sputum bacterium conversion rate in two groups had no statistical significance(x2=0.1 10,P＞0.05).Conclusion The incidence rate of tuberculosis was high in floating population of Pinghu City.The TB patients in floating population could receive the same treatment as those in local population through DOTS treatment.

We report the results of detecting M. lepraespecific antigen--phenolic glycolipid I (PGL--I) with modified M-Dot-ELISA in sera from 75 cases of household contacts (HC)of leprosy patients, which were all seropositive by Gelatin Particle Agglutination Test (MLPA)and ELISA. The results indicate that: (1 ) 16/75 (21. 3 % ) are antigen positive. The rates of positivity in HC of MB patients are much higher than those in HC of PB patients,the difference (P

We expressed 17-hydroxysteroid dehydrogenase10 (17β-hsd10) recombinant protein, prepared anti-17β- hsd10 polyclonal antibodies and established sandwich enzyme linked immunosorbent assay (ELISA) test for detection of 17β-hsd10. RT-PCR was used to get the gene of 17β-hsd10 of mouse liver, and a prokaryotic protein expression system pET 15b-17β-hsd10/Escherichia coli BL21 (DE3) which induced with isopropyl-1-thio-β-galactopyranoside (IPTG) for recombinant protein expression was constructed subsequently. The target protein purified using His-Binding-resin column was used to immunize BALB/c mice and rabbits, serum total IgGs from immunized animals were purified by ammonium sulfate precipitation method. We established a Double-antibody Sandwich enzyme linked immunosorbent assay about 17β-hsd10 using the two antibodies we prepared. We got the concentration of 1.5 mg/mL of 17β-hsd10 protein with molecular weight of 29.5 kDa, and polyclonal antibodies from mouse and rabbit with the tite 1.25 x 10(4) and 2.5 x 10(4) respectively. The concentration of 0.1 g/mL of 17β-hsd10 can be detected by the Double-antibody Sandwich ELISA we established, and the assay was sensitive and specific. It can be widely used in clinical and experimental study.

Objective To study the corelation of mucosal involvement and corticosteroid dosage in the control of bullous pemphigoid(BP). Methods One hundred and three in-patients with bullous pemphigoid hospitalized during 1988 - 2002 were retrospectively analyzed for their mean corticosteroid dosage for controlling the disease and the duration for complete relieving the skin lesions, as well as the duration to start corticosteroid tapering. All the patients were divided into two groups: group A (37 cases) with mucosal involvement and group B (66 cases) without mucosal involvement. Results The mean corticosteroid dosage used to control the disease in group A was much higher than that in group B (t = 3.488, P 0.05). Conclusion Patients with mucosal involvement require a higher dosage of corticosteroids to control the disease.

Objective To evaluate the diagnostic value of deep venous thrombosis(DVT)on lowerlimb venous ultrasonography combined with right ventricular dysfunction (RVD) on transthoracic echocardiography(TTE) in patients with acute pulmonary thrombo embolism(PTE). Methods This prospective multicenter control trial included 520 patients with confirmed acute PTE from 41 hospitals between June 2002 and February 2005.Results The incidence of RVD and DVT was associated with the severity of PTE.There were 57.0%(207/363)patients with RVD,49.6%(1 80/363)patients with DVT,265(73.0%)patients with RVD and/or DVT,and 121(33.3%)patients with combined sign of DVT plus RVD in the whole population.As to major PTE population,206(99.5%)patients had RVD and 121 (58.5%)patients had DVT.In addition,the rate of RVD was much greater in proximal PTE than in lobar PTE and segmental PTE(78.7%,51.4%and 21.7%,respectively,P＜0.001).DVT occurred more frequently in proximal PTE than in lobar PTE and segmental PTE(61.7%,46.8%and 37.0%,respectively,P＜O.001).The incidence of the combined sign was 51.1%,24.3%and 8.7%,respenctively (P＜0.001).Conclusions The incidence of the combined sign of RVD plus DVT was associated with the severity of PTE and the localization of emboli.The combined sign of RVD plus DVT help diagnose major PTE especially in emergency department.

The module design of pharmaceutical superfine pulverization matched up GMP was attempted. The integral of mechanism and electricity into the whole pulverization process was designed and established.

Objective To explore the protective effect of folic acid supplementation in different ways on lipopolysaccharide-induced external malformations and skeletal malformations in mice.Methods The pregnant mice were divided into six groups randomly,including saline control group,FA control group,LPS group,LPS+FAig group,LPS+FAip group,and LPS+FAdw group.All dams were medicated on gestational day 8～12,and then sacrificed on gestational day 18,for each litter,the number of live fetuses,dead fetuses,resorption fetuses and external malformations of live fetuses were all counted.All fetuses were subsequently evaluated the skeletal malformations.Results A low dose of LPS injection during the second trimester resulted in external and skeletal malformations.Exencephaly and encephalomeningocele were two of the most common external malformations,skeletal malformations consisted mainly of the incompletion of supraoccipital ossification,sternal malformation and rib malformation.FA supplementation by three ways all attenuated the external and skeletal malformations.And the best protective effect was by oral administration.The incidence of external,sternal and rib malformation was all decreased.Conclusions Three ways can prevent the mice during the second trimester from the external and skeletal malformations caused by LPS injection,and the best protective effect was by intragastric administration.

Objective To observe the clinical effect of combination of Tongxiening granule and Mesalazine on treating mild and moderate ulcerative colitis(UC) .Methods Totally 380 patients with mild‐to‐moderate UC diagnosed through endoscopy were allocated to the control group (n=190) and observation group(n=190) .For the observation group ,patients were remedied with the combination of Tongxiening Granules and the Mesalazine by oral administration for eight weeks ,meanwhile the control group only received the Mesalazine for eight weeks .The total effective rate of the two groups were statistically analyzed ,and the levels of ser‐um MMP‐2 and MMP‐9 before and after treatment in the two groups were measured .The expression of S100A12 and RAGE were detected by immunohistochemistry SP method .Results The total effective rate of the observation group and the control group was 94 .74% and 89 .47% respectively ,and the difference was statistically significant(P<0 .01) .After treatment ,the expression levels of MMP‐2 and MMP‐9 in the two groups were decreased ,additionally the expression levels in the observation group was lower than those in the control group ,and the difference was statistically significant (P< 0 .01) .After treatment ,the expression levels of RAGE and S100A12 in the observation group were decreased ,and there was a significant difference when compared with the control group(P<0 .01) .Conclusion Combined application of Tongxiening Granules and Mesalazine in treating patients with mild‐to‐mod‐erate UC could better improve clinical symptoms and bring better therapeutic effect than single use of Mesalazine .
