There were 538 males and 282 females, aged (56±13)years. Observation indicators: (1) clinical charac-teristics of cirrhotic portal hypertension patients; (2) overall prevention and treatment of EVB in cirrhotic portal hypertension patients; (3) prevention and treatment of EVB in cirrhotic portal hypertension patients from different grade hospitals. Measurement data with normal distribution were represented as Mean± SD. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test. Results:(1) Clinical characteristics of cirrhotic portal hypertension patients: of 820 cirrhotic portal hypertension patients, 271 cases were in compensated stage and 549 cases were in decompensated stage. Of the 271 cases in compensated stage, there were 183 maels and 88 females, aged (53±12)years. There were 185 Han people, 85 Hui people and 1 case of other ethic group. The etiological data of liver cirrhosis showed 211 cases of viral hepatitis B, 4 cases of alcoholic liver disease, 8 cases of viral hepatitis C, and 48 cases of other etiology. There were 235 cases of Child-Pugh grade A and 36 cases lack of data. Of the 549 cases in decompensated stage, there were 355 males and 194 females, aged (57±14) years. There were 373 Han people, 174 Hui people and 2 cases of other ethic group. The etiological data of liver cirrhosis showed 392 cases of viral hepatitis B, 33 cases of alcoholic liver disease, 10 cases of viral hepatitis C, and 114 cases of other etiology. There were 80 cases of Child-Pugh grade A, 289 cases of grade B, 170 cases of grade C and 10 cases lack of data. (2) Overall prevention and treatment of EVB in cirrhotic portal hypertension patients: of 271 patients in compensated stage, 38 cases received non-selective β-blocker (NSBB) therapy, 16 cases received endoscopic treatment, 6 cases received interventional therapy. Of 549 patients in decompensated stage, 68 cases received NSBB therapy, 46 cases received endoscopic treatment, 28 cases received interventional therapy. (3) Prevention and treatment of EVB in cirrhotic portal hypertension patients from different grade hospitals: of 271 patients in compensated stage, 181 cases came from tertiary hospitals, of which 28 cases received NSBB therapy, 15 cases received endoscopic treatment, 6 cases received interventional therapy. Ninety cases came from secondary hospitals, of which 10 cases received NSBB therapy, 1 cases received endoscopic treatment. There was no significant difference in NSBB for prevention of EVB between tertiary and secondary hospitals ( χ2=0.947, P>0.05), while there was a significant difference in endoscopic treatment for prevention of EVB between tertiary and secondary hospitals ( χ2=5.572, P<0.05). Of 549 patients in decompensated stage, 309 cases came from tertiary hospitals, of which 22 cases received NSBB therapy, 29 cases received endoscopic treatment, 22 cases received interventional therapy. Two hundreds and fourty cases came from secondary hospitals, of which 46 cases received NSBB therapy, 17 cases received endoscopic treatment, 6 cases received interven-tional therapy. There were significant differences in NSBB and interventional therapy for prevention of EVB between tertiary and secondary hospitals ( χ2=18.065, 5.956, P<0.05). Conclusions:The proportion of receiving EUB prevention in cirrhotic portal hypertension in Ningxia is relatively low. For patients with compensated liver cirrhosis, the proportion of NSBB therapy and endoscopic treatment in the secondary hospitals was lower than that in tertiary hospitals. For patients with decompensated liver cirrhosis, the proportion of interventional treatment in secondary hospitals is lower than that of tertiary hospitals, but the proportion of NSBB in secondary hospitals taking is higher than that of tertiary hospitals.
ABSTRACT
Objective To investigate the genotype distribution of microsatellite locus CAI among Candida albicans ( C.albicans ) strains and to evaluate its relationship with the epidemic of vulvovaginal candidiasis ( VVC) in Guizhou region .Methods Ninety independent C.albicans strains isolated from pa-tients with VVC in Guizhou were investigated based on single-strand conformation polymorphisms ( SSCP ) and GeneScan analysis .The genotypes of C.albicans strains were identified by microsatellite locus CAI pol-ymorphism analysis .The gene polymorphism and the cluster of C.albicans strains were analyzed by using software SPSS 19.0.A logistic regression model was used to analyze the relationship between genotype distri -bution of CAI microsatellite among C.albicans strains and VVC infection .Results Twenty-seven distinct CAI genotypes with various patterns were identified from 90 C.albicans strains by GeneScan analysis .Clus-ter analysis showed that the C.albicans strains were classified into three clusters ( ClusterⅠto Cluster Ⅲ) . Three predominant genotypes including 30-45, 32-46 and 30-46 and other 7 highly similar genotypes be-longed to clusterⅡthat accounted for 70.0%(63 strains) in all strains.The odds ratio for the predominant genotypes associated with VVC infection was 4.3.Conclusion The predominant distribution of genotypes was observed among the isolated C.albicans strains.The predominant genotypes of C.albicans were highly associated with the occurrence of VVC .

ABSTRACT
Objective To explore the role of matrix metalloproteinase 9(MMP-9)and tissue inhibitor of metalloproteinase-1(TIMP-1)in patients with acute exacerbation of severe chronic obstructive pulmonary diseases (AECOPD)treated with glucocorticoids.Methods The serum levels of MMP-9 and TIMP-1 were measured by ELISA in 41 patients with AECOPD before and after treatment with glucocorticoids and in 40 patients with regular methods(control group).Results ①After treatment with glucocorticoids,the serum levels of MMP-9(189.25±52.38)μg/L、TIMP-1(198.38±43.45)μg/L,ratio of MMP-9/TIMP-1(0.92±0.37)were decreased significantly than before((246.10±68.64)μg/L,(217.63±62.34)μg/L,(1.09±0.23))(P<0.01,P<0.05,P<0.05);but there were no differences(P>0.05)in regular methods(control group);② After treatment with glucoeorticoids, FEV_1、FEV_1%((0.83±0.35)L,(46±17)%)were impmved than before((0.72±0.48)L,(34±15)%)(P<0.05).Conclusions After treatment with glucocorticoids,the serum levels of MMP-9、TIMP-1、ratio of MMP-9/TIMP-1 from patients with COPD were decreased significandy,and FEV_1、FEV_1%were improved significant;Glucocorticoids can alleviate severs AECOPD to some degrees,which might be related to improving the imbalance of MMP-9/TIMP-1.
ABSTRACT
Objective To investigate the adjustment of immunosuppression and prevention of infections in lung after renal transplantation.Methods 253 cases of pulmonary infections after renal transplantation between January 1999 to March 2004 were analyzed. After 2003, postinduction period, the blood concentrations of CsA and FK506 were maintained at 0.125~0.166 ?mol/L and 5 ?g/L respectively. The oral dose of MMF was 1 g every day. Results The creatinine levels were stable 253 patients after treatment. Among 253 cases, 229 cases were cured (90.51 %) and 24 died (9.49 %). After adjustment of immunosuppressants, common pulmonary infections and severe pulmonary infections were decreased.Conclusions Infection in lung was a severe complication after renal transplantation. Timely treatment, nursing care and adequate adjustment of immunosuppression may achieve satisfactory effects in preventing lung infection.
