Objective To investigate health equity status of urban dwellers with different social stratification and provide evidence for health promotion.Methods 1,007 urban dwellers were surveyed in Zhejiang province in a stratified sampling based on their income,occupation and education,with their health equity analyzed.Results The proportion of urban dwellers to participate in social health insurance reached 97.5％,a proportion of statistical significance (P＜0.05).The two-week prevalence rate and two-week attendance rate of urban dwellers of different social stratification has no significant difference,but the rate of sickness without attending was significantly negatively correlated to social stratification.The proportion of no visiting because of poverty was 23.1％ in the lower social class,3.2％ in middle and lower class,and 0％ in the middle and upper class,a difference being statistically significant (P＜0.001).The outpatient clinic of first choice and ranking of the hospital was positively correlated to social stratification.Conclusion There is health inequity for urban dwellers with different social stratification,for which the government should pay more attention to lower social class.

Objective:To investigate the mRNA and protein expression of suppressors of cytokine signaling in human villa and decidua of first trimester gestation.Methods:We first obtained villous tissues and decidual tissues from 38 women who had undergone selective termination at 7-9 weeks of normal gestation.The transcripts of SOCS1,SOCS2,SOCS3 in villous tissues and decidual tissues were detected by using semi-quantitative reverse transcriptase polymerase chain reaction.The mRNA of SOCS1,SOCS2,SOCS3 from cultured trophoblasts and decidual stromal cells were detected.Also the protein expression of 35 pregnant women were detected by western blot.Immunohistochemistry analysis revealed the location of SOCS1,SOCS2,SOCS3 in materno-fetal interface.IL-10 and IFN-? secreted by cells in vitro were detected by ELISA.Results:The expression of SOCS1,SOCS2,SOCS3 were found in mater-fetal interface,while positive expression of SOCS3 in villi/decidua was 73.7%/71.1%,and that of SOCS2 was 50.0%/39.5%,then SOCS1 expression was 34.2%/31.6%.The protein expression of SOCS1,SOCS2,SOCS3 were similar to the transcription level.SOCS1,SOCS2,SOCS3 were mainly expressed in villi and decidual stroma.Trophoblasts and decidual stromal cells were not found the expression of SOCS1,but the low level mRNA of SOCS2,SOCS3 without serum,and IL-10 secreted by them increased significantly(P

Objective To study the effects of allopurinol in different dose on the cardiac function of chronic heart failure rats induced by adrimycin. To explore dose-dependency of allopurinol in improving blood vessel endothe-lium function and cardiac ventricle remodeling of the rats heart, as to supply evidence and new sight in clinical treat-ment of congestive heart failure. Methods 40 Sprague-Dawley male rats were randomly divided into four groups: normal control group (group A)、model control group (group B)、low-dose allopurinol group (group C)、high-dose allopurinol group (group D). The heart failure model was made by administering adriamycin to rats. After the model myocardial pathological changes were detected. Results Compared with the normal control group, the weight and heart weight of rats in model control group and allopurinol groups were obviously lessen (group A=(300.10± 9.85)g,group B=(200.67±9.91)g, group C=(233.14±9.42)g,group D=(248.25±13.34) g;group A= (828.30±50.97) nag, group B=(681.50±16.97) mg, group C=(743.00±17.20) nag, group D=(784.88± 36.83) mg,P<0.05). Heart weight indexes were all incerased ( group A=(2.76±0.15) mg/g, group B=(3.41± 0.17) mg/g, group C=(3.26±0.76) mg/g, group D=(3.11±0.65) mg/g, P<0.05). The hemedynamics resuh showed that myocardial contractile force were enhanced in drug groups. The level of NO, SOD were increased in the allopurinol groups compared with the model control group (group B: NO=(41.55±6.28) μmol/L, group C: NO= (52.47±5.59) μmoL/L,group D:NO=(61.04±4.26) μmoL/L; group B:SOD=(63.83±6.40) U/ml,group C: SOD=(76.29±7.99) U/ml, group D: SOD=(100.13±7.43) U/ml, P<0.05) and MDA levels were obviously decreased (group B: MDA=(9.70±1.08) μmol/L, group C: MDA=(6.64±0.34) μmol/L, group D: MDA= (5.72±0.71)p.moVL,P<0.05). The level of NO, SOD were obviously increased in the allopurinol of high-dose group compared with low-dose allopurinol group(P<0.05). MDA levels were obviously decreased(P<0.05). The myocardial pathological changes were relieved obviously in the allopufinol groups. Conclusion Allopurinol improves blood vessel endothelium function dose-dependently. High-dese allopurinol obviously decreases MDA, improve NO, SOD, thereby can improve the cardiac function of heart failure.

Objective To discuss the significance of high-risk human papilloma virus ( HR-HPV) detection by hybrid capture 2 (Hc-2) in managing the women with atypical squamous cell of undetermined significance (ASCIIS) and low grade squamous intraepithelial lesion (LSIL) of thin prep liquid-based cytology (TCT). Methods One hundred and seventy-eight women with ASCUS and 108 women with LSIL were studied. The infection of HR-HPV in the women was analyzed.

Conclusion HR-HPV detection by Hc-2 is an effective measure in managing the women with ASCUS and LSIL of TCT.

Objective To probe into the inequality found in primary public health service available to the migrant population and permanent residents. Methods With on-site interviews, 581 migrant workers and 581 permanent residents in a county in Zhejiang province were surveyed, to learn the inequalities between the two in the expenditure, access and outcomes of the public health service accessible to each. Results only 7. 8% of the migrant population ever had access to medical aid, a ratio far below that of the permanent residents; 40. 9% of the migrant population may turn down medical service beyond their affordability, a ratio far higher; for the migrant population, their ratio of gynecological checkup is 58. 7%, lower than that of the permanent residents (67. 7%). Conclusion Resources and financial allocation to institutions of public health should be enhanced, and social medical and insurance system should be developed and improved, in an effort to encourage the equality of primary public health services accessible to various sectors of the population.

Objective To investigate the relations between intrauterine asphyxia and peroxidation and newborn hypoxic-ischemic encephalopathy(HIE). Methods The levels of superoxide dismutase (SOD) and malondialdehyde (MDA) in cord blood of 60 newborns with intrauterine asphyxia during labor(which was divided into two groups,39 cases with asphyxia in groupⅠ, and 21 cases with asphyxia in groupⅡ),and in 30 newborns without intrauterine asphyxia(control group) were determined. The levels of SOD and MDA in cord blood of newborns with HIE were compared with those in newborns without HIE. The incidence of HIE was estimated simultaneously. Results (1) The levels of SOD were (12 896?247) U/g Hb in groupⅠ, (9846?268) U/g Hb in groupⅡ, (17 282?134) U/g Hb in control group, significantly lower in the former two groups compared with control group, while the level of SOD in group Ⅰ was higher than that in group Ⅱ(P121 min group, and the levels of SOD was (9786?249) U/g Hb.(2)The levels of MDA were (6.3?0.4) ?mol/L in group Ⅰ, (8.6?1.5) ?mol/L in group Ⅱ, and (4.1?0.5) ?mol/L in control group, significantly higher in the former two groups compared with control group (P

Objective To identify the quality of life (QOL)and major influencing factors for migrant workers in Zhejiang province.Methods The QOL of 1217 migrant workers and 1387 permanent urban residents in Zhejiang province were measured by WHOQOL-BREF scale (Chinese version)in a stratified sampling.A multiple linear regression model was used to analyze the relationship between the factors and the scores of the four domains.Results There were no significant statistical differences(P＞0.05)found in the scores of physical health,social relationship and general health between migrant workers and urban residents.Their scores of psychological health,surrounding conditions and general quality of life,however,were found lower than urban residents (3.5 ± 0.8 vs 3.6 ± 0.8).Influencing factors for their psychology were education,family conflicts and appetite; those for their surrounding conditions were daily average work hours and appetite.Conclusion Given improvements in the quality of life of migrant workers,rooms to improve were found in such scores as psychological health and surrounding conditions.

OBJECTIVE:To study the relationship between cisplatin-resistant of human ovarian cancer cells (SKOV3) and Toll-like receptor 9 (TLR9) under hypoxia. METHODS:Immunofluorescence method was used to detect the TLR9 expression in rupture and intact membranes SKOV3. SKOV3 was taken,adding cisplatin,then CCK-8 was used to detect cell inhibition rate af-ter 6,12,24 h of added into TLR9 specific agonists CpG-ODN 2006 (group A) and its isotype control CpG-ODN 2006 control (group B). SKOV3 or SKOV3 pretreated by 0(not added),1,10,102,103 μmol/L TLR9 specific antagonist chloroquine for 3 h were taken,adding cisplatin,cell inhibition rate was detected after 24 h of added into SKOV3 normoxia(21% O2),hypoxia(1%O2)incubating 6,12,24 h,HICR under hypoxia in pretreatment was calculated. Western blot method was used to detect the multi-drug resistance associated protein(MRP)expression in SKOV3 under the conditions of normoxia 24 h cell supernatant(group C), hypoxia 24 h cell supernatant(group D),hypoxia 24 h cell supernatant+10 μmol/L chloroquine(group E). RESULTS:TLR9 was expressed in both cell membrane and cytoplasm of SKOV3. Compared with group A,cell inhibition rate in group B was decreased (P<0.01). Compared with normoxia cell supernatant,cell inhibition rate was decreased after hypoxia cell supernatant (P<0.05). Compared with not added chloroquine,adding 10,102 μmol/L chloroquine can obviously decrease HICR(P<0.01),and the most significant decrease was showed when using hypoxia 24 h cell supernatant+10 μmol/L chloroquine. Compared with group C,MRP expression in group D was strengthened (P<0.01);compared with group D,MRP expression in group E was weakened (P<0.01). CONCLUSIONS:TLR9 receptors can be activated under hypoxia,and cause SKOV3 to cisplatin-resistance,the effect may be related with up-regulating MRP expression.

Objective Currently , the targeted therapy is the first-choice treatment of advanced non-small cell lung cancer (NSCLC) in with epidermal growth factor receptor (EGFR) mutations, but few studies have been reported on the relationship between immunohistochemical markers and the EGFR mutation.The aim of this study is to analyze the relationship of the EGFR mutation with the ex-pressions of thymidylate synthetase (TS), excision repair cross-com-plementation group 1 ( ERCC1 ) , β-tubulin-III, and ribonucleofide reductase large subunit-l ( RRM1) in NSCLC. Methods We retro-spectively analyzed 336 cases of NSCLC treated in the Department of Medical Oncology , the Affiliated Hospital of Inner Mongolia Medical University, from June 2014 to December 2015 and examined 29 EGFR mutations.We divided the patients into a mutation and a non-mutation group, performed immunohistochemical staining of the TS, ERCC1,β-tubulin-III and RRM1 proteins and compared their expressions in the NSCLC tissue between the two groups . Results EGFR mutations were found in 138 ( 41.07%) of the 336 NSCLC patients but not in the other 198 ( 58.93%) .The expression of TS was significantly lower in the mutation than in the non-mutation group (9.42%vs 39.39%, P<0.05), and so was that of β-tubulin-III (44.2%vs 60.1%, P<0.05).EGFR mutations were correlated with decreased expressions of TS (r=-0.332, P<0.05) andβ-tubulin-III (r=-0.157, P<0.05).Multivariate regression analysis showed that the risk of EGFR mutations was 2.109 times higher in the fe-male patients than in the males (OR=2.109, 95%CI:1.268-3.509), 24.265 times higher in the adenocarcinoma than in the adeno-squamous carcinoma patients (OR=24.265, 95%CI:3.508-167.845), 15.2 times higher in the squamous carcinoma than in the ade-nocarcinoma patients (OR=15.200, 95%CI:4.480-51.569), 2.364 times higher in the lung biopsy specimens than in the surgically treated patients (OR=2.364, 95%CI:1.266-4.413), and 6.171 times higher in the patients with lowly expressed than in those with highly expressed TS (OR=6.171, 95%CI: 3.145-12.109). Conclusion The decreased expressions of TS and β-tubulin-Ⅲ in NSCLC indicate the mutation of the EGFR gene.
