ObjectiveTo probe into the maternal care utilization by minority women, for the purpose of policy recommendations on better maternal care in minority areas. MethodsA combination of stratified random sampling and typical sampling was made on 445 married women of reproductive age in six counties in Yunnan, Guizhou, Qinghai and Tibet provinces, a field survey on their utilization of maternal care services. ResultsTheir average prenatal detection rate is 78.24％, a level lower than the national rural average of 93.7％ and grade-4 rural average of 81.2％ in 2008; their post partook rate is 30.7％, lower than the national rural average of 54.3％ and grade-4 rural average of 58.9％ in the same period; their average coverage rate is 52.18％, a level lower than the national rural average of 87.1％and grade-4 rural average of 64.3％ in 2008. ConclusionThe maternal care utilization is found to be low for women in minority areas. Effective solutions are expected for payment of indirect expenditure of hospital delivery; better health education for enhancing health knowledge and health awareness of minority women; effective incentive mechanism for village doctors, consolidating the base of the three-level healthcare network.

Objective: In order to validate the effectiveness of methods of defining poverty caused by illness which are based on catastrophic health expenditure and impoverishment health expenditure, originated from relative costs theory.Results: This paper uses empirical approach to explore the definition methods by comparing the original methods with modified methods and defined population with the actual situation of poverty alleviation.Results: Study results show that the catastrophic health expenditures incurred ratio is about 20% and shows the aggregation of both low-income and high-income groups.The impoverishment health expenditure incurred ratio is about 12% and they mainly are families at the edge of poverty line.This study found that 70% of the families defined based on our method did not receive medical assistance in reality.Conclusion: Therefore, the definition methods based on relative costs theory are of great value in Chinese medical assistance systems for defining poverty caused by illness.Grouping based on household ability to pay could improve the methods' operability and effectiveness.

ABSTRACT:Objective To investigate the clinical features of seronegative rheumatoid arthritis (RA)in western China and its outcomes after one-year treatment with disease modifying anti-rheumatoid drugs (DMARDs) so as to provide evidence for effective therapy.Methods We made a retrospective analysis of 240 RA patients treated in our department from May 2013 to June 2014.We compared the 47 seropositive and 25 seronegative RA patients in clinical features,laboratory parameters and outcomes after one-year DMARDs medication.Results The percentage of seronegative RA was 10.4% (25/240).The number of swollen small joints was significantly smaller in seronegative RA group (P<0 .0 1 ).Compared with those in seropositive RA,the level of hemoglobin was lower,the level of platelets was higher,and the level of alkaline phosphatase was lower in seronegative RA (P<0 .0 5 ).The remission rate was higher in seronegative RA group than in seropositive RA group after one-year DMARDs administration (P<0.05).Conclusion Seronegative RA is not rare in clinic.Even though seronegative RA patients often present fewer swollen small joints, it is difficult to distinguish between seronegative and seropositve RA just based on the clinical features.Besides,hematological damage is more severe in some patients with seronegative RA.Only after one-year treatment with DMARDs,the remission rate is higher in seronegative RA patients than in seropositve RA ones.

Objective To study the serum HBV cccDNA and genotype of hepatitis B virus in children in Gansu province.Methods 124 HBV-DNA positive children were randomly selected,with 84 males and 40 females.Among the 124 patients,65 were HBV carriers,59 were chronic hepatitis(31 mild,18 moderate and 10 severe).Genotypes of their serum HBV,liver function,HBV-DNA load and serum HBV cccDNA were detected.Results In the moderate and severe groups,HBV cccDNA positive rate was higher than that in the HBV carriers or the mild group(F=25.429,P＜0.01).The HBV cccDNA detection rate in HBeAg positive group was higher than that in the HBeAg negative group(F=28.386,P＜0.01).In the HBV cccDNA positive group,glutamic-pyruvic transaminase,glutamic-oxaloacetic transaminase,total bilirubin were higher than that in the negative group(t respectively 13.241,11.347,15.013,P＜0.01).Both C and B genotypes appeared to be the majority while C genotype was dominant in the 124 cases of children hepatitis,with the rest as B/C and some other genotypes.The positive rate of HBV cccDNA C genotype was higher than that of the genotype B(F=23.216,P＜0.01)and the negative rate of HBV cccDNA genotype was higher than that of the C genotype(F=26.364,P＜0.01).Conclusion Higher detection rate was found inthose more severe cases in the peripheral blood streams.HBV cccDNA and genotype testing might better reflect the level of HBV replication and the clinical severity of the disease,showing its guiding role in clinical diagnosis and treatment of hepatitis B.

OBJECTIVETo prepare monoclonal antibodies (mAbs) against enoyl-CoA hydratase 1 (ECH1).

METHODSNormal human liver tissues were homogenized, and the mitochondria were isolated by differential centrifugation. The total mitochondrial proteins were used to immunize BALB/c mice to prepare mAbs by routine hybridoma technique. The mAbs were characterized by ELISA, Western blotting and immunohistochemistry. The specificity of the antibody was identified by mass spectrometry (MS) following immunoprecipitation (IP) and confirmed by Uni-ZAP expression library screening.

RESULTSOne clone of the hybridoma BGB095 secreting specific mAb against ECH1 was obtained. The mAb was identified to belong to Ig subclass IgG1 and could be used in ELISA, Western blotting, immunohistochemistry, and immunoprecipitation.

CONCLUSIONA hybridoma cell line stably secreting specific mAb against ECH1 has been established. The specific mAb against ECH1 can be of great value for functional and distribution studies of ECH1.

OBJECTIVETo investigate the relationship between genotype of hepatitis B virus and hepatitis B virus related-glomerular nephritis in (HBV-GN) children.

METHODTotally 176 HBV-DNA positive children with chronic hepatitis B were randomly collected. Among the 176 patients, 92 were HBV carriers, 84 were cases with chronic hepatitis. The genotypes of their serum HBV, liver function, and HBV-DNA load were detected. When children showed nephrotic syndrome, renal biopsy was performed.

RESULTOf the serum samples of 176 cases, 85 (48.3%) were genotype C, 72 (40.9%) were genotype B, 13 (7.4%) were genotype B/C, and 6 (3.4%) were non-B/C genotype which were excluded. Among the analyzed 157 cases, the ratio of HBV-GN in the HBeAg positive group (78.3%) was significantly higher than that in the negative group (21.7%) (χ(2) = 18.301, P < 0.001). And, the ratio of HBV-GN in the genotype C group (73.9%) was significantly higher than that in the genotype B group (26.1%) (P < 0.039). The ratio of hematuria or proteinuria in the genotype C group (20%, 18.8%) was significantly higher than that in the genotype B group (8.3%, 5.6%) (P < 0.039; P value = 0.013); and the alteration of ALT or C3 in the genotype C group (10.2%, 15.3%) was more frequent than those in the genotype B group (2.8%, 2.8%) (P = 0.005; P = 0.008). There were no significant differences in kidney dysfunction or hepatomegaly. Further, the ratio of HBV-GN was more significantly frequent in HBV-DNA highly loading group (79.2%) than which in HBV-DNA lowly loading group (20.8%) (P = 0.000). Finally, in HBV-GN group, genotype C cases (88.2%) more frequently had high HBV-DNA load condition than genotype B cases (11.8%) (P = 0.021).

CONCLUSIONChildren with HBV infection in Gansu province showed mainly genotypes C or B, while genotype C seemingly predominant. Patients with genotype C more frequently showed proteinuria or hematuria. The high HBV-DNA load may be related with HBV-GN. It is a potential reason in the mechanism of HBV-GN that patients with genotype C had more possibility to have HBV-DNA high load. Analysis of HBV genotype for HBV patients maybe helpful in diagnosis and treatment.
