OBJECTIVE:To provide reference for further comprehensive evaluation of the improvement of the accessibility of family medicines after the implementation of the new health care reform. METHODS:Sampled as 180 households from 2 urban ar-eas,2 counties and 2 rural areas in Chengdu,a questionnaire survey was adopted based on the WHO’s manual for the Household Survey to Measure Access and Use of Medicines to investigate the situation of drug use,storage and accessibility,and the results were statistically analyzed. RESULTS:Totally 180 questionnaires were sent out,179 were effectively received with effective recov-ery of 99.44%. In the terms of medicines taken for the acute illness,there were more than 60% rural households obtained drugs from the public health care facilities,while more than 60% counties households purchased drugs in public medical and health insti-tutions;in the terms of medicines taken for the chronic illness,the proportion of households reporting a chronic illness who did not take any medicines was low(3.80%);in terms of medicines storage,the proportion of households without reserve drugs was low (13.41%). In terms of drug accessibility,the proportions of respondents who agreed that the location and opening hours of their public healthcare facility were convenient were high;there was no situation for“patients did not take prescribed drugs because med-icines were not available at the healthcare facility and drug store”,while more than 95% respondents who agreed that drugs were available at their public health care facilities and drug stores;the essential medicines in the household use of chronic drugs in Chengdu accounted more than 60%;more than 85% can afford the drug costs,while the proportion of the monthly costs for acute illness and chronic illness in the total month costs was low;the health insurance coverage reached 90% in the survey households, but the proportions of households which could reimburse acute,chronic illness drug cost were lower(14.13% and 12.66%). CON-CLUSIONS:At present,the level of drug accessibility in Chengdu is high;the implementation of National Essential Medicines System has a positive effect on reducing the economic burden of chronic disease family. But there are shortcomings in the Medicare reimbursement levels and antibiotics use,it is suggested to take effective measures to solve it,such as exploring the stable and ef-fective medical insurance fund raising channels,improving the compensation level and the level of insurance reimbursement,formu-late and implement the corresponding antibacterial drugs supervision system and regulate the rational use of antibiotics in residents.

Objective To explore the clinical characteristics of treatment?resistant depression ( TRD) and of its relevance with thyroid hormones. Methods 43 patients with TRD and 48 patients with non?TRD were as?sessed with 17?item Hamilton depression scale ( HAMD?17) and Hamilton anxiety scale ( HAMA) . The serum lev?el of thyroid?stimulating hormone ( TSH) ,total triodothgronine ( TT3) ,total thyroxine ( TT4) ,free triodothgronine ( FT3) and free thyroxine ( FT4) were determined by radioimmunoassay. χ2 test and t test were used for statistic a?nalysis. The quantitative relation of FT3 level with TRD was analyzed and the value of FT3 level in TRD diagnosis was evaluated by ROC curve.Results Compared with non?TRD patients,the TRD patients showed a younger dis?ease onset age ((16.98±2.25)years vs (23.50±3.38)years) and a longer disease course ((10.14±6.47)years vs (5.48±4.15)years) for total disease course;(60.35±23.64)months vs (5.00±3.40)months for current disease course),and had shorter education years ((8.53±1.72)years vs (11.04±2.07)years) and higher HAMD total scores (19.09±1.59 vs 15.69±2.38) and behavior retarding factor scores (8.72±0.98 vs 4.98±1.63). In addition, the FT3 level of TRD patients was lower than that of non?TRD patients ((3.92±0.15)pmol/L vs (4.16±0.20) pmol/L).All the above differences between two groups were statistically significant (P<0.05). The logistic regres?sion analysis showed that the risk of suffering TRD increased by 1. 006?fold when FT3 level reduced 0. 1 pmol/L (OR=2.006,95%CI=(1.501,2.681). The area under ROC curve was 0.821 (P<0.001) with its 95% confidence interval of (0.734,0.907). Conclusion Compared with non?TRD patients,TRD patients have a longer disease course,a younger disease onset age, a lower education level, higher HAMD total scores, more severe retardation symptoms,and a lower FT3 level. The serum FT3 level has a high reference value in diagnosis of TRD.

To study the effect of exogenous oxygen, we added water solution of paraquat to 7 d cultures of Coriolus versicolor for the next 148 h. Enzyme exudation and biochemical process were investigated on the addition of paraquat. We found that compared with the control (without paraquat), the addition of 30 micromol/L paraquat stimulated the activity of manganese dependent peroxidase (MnP), lignin peroxidase (LiP), and laccases (Lac) 7, 2.5 and 1.3 times, respectively. Also, addition of paraquat enhanced activity of superoxide dismutase (SOD) and catalase (CAT) in the first 48 h. Impact of paraquat on ligninolytic enzymes was significant than that on antioxidant enzyme. Addition of paraquat enhanced phenolic compounds and formaldehyde of cultures too. And concentration of malondialdehyde was increased in the first 24 h. The results showed that addition of paraquat promoted oxidative stress, but the antioxidant systems of the fungal strain are sufficient to prevent mycelia from oxidative stress. As exogenous oxygen, paraquat might be a useful substrate in degradation of lignocellulose.

OBJECTIVETo study correlations of polychlorinated biphenyls (PCBs), DIOXIN, and polybrominated diphenyl ethers (PBDE) with thyroid stimulating hormone(TSH) in children, and assess the impact on children's health.
METHODSThree hundred and sixty nine children aged from 6 to 8, including 195 from Luqiao, the computer E-waste recycling area, and 174 from Longyou, the control area, were selected for this investigation to elucidate the correlation of PCBs, DIOXIN, and PBDE with TSH in children's blood samples. The children had a physical examination and their blood levels of PCBs, DIOXIN, PBDE, and TSH were detected after sample collection.
RESULTSIn the E-waste recycling area, the contents of PCBs, PBDE, DIOXIN, and TSH in the blood samples of children were 484.00 ± 84.86 ng·g(-1) lipid weight, 664.28 ± 262.38 ng·g(-1) lipid weight, 26.00 ± 19.58 ng·g(-1) lipid weight and 1.88 ± 0.42 μIU/mL (serum) respectively, while in the control area, the PCBs, PBDE, DIOXIN, and TSH contents were 255.38 ± 95 ng·g(-1) lipid weight, 375.81 ± 262.43 ng·g(-1) lipid weight, 39.64 ± 31.86 ng·g(-1) lipid weight, and 3.31±1.04 μIU/mL respectively.
CONCLUSIONThe health status of children in the control area are better than that in the contaminated area. Among children who are exposed to persistent organic pollutants, the pollutant content increases significantly in their serum, and the distribution of TSH levels in their bodies are also affected.

Background:
Arctic-like (AL) lineages of rabies viruses (RABVs) remains endemic in some Arctic and Asia countries. However, their evolutionary dynamics are largely unappreciated.
Objectives:
We attempted to estimate the evolutionary history, geographic origin and spread of the Arctic-related RABVs.
Methods:
Full length or partial sequences of the N and G genes were used to infer the evolutionary aspects of AL RABVs by Bayesian evolutionary analysis.
Results:
The most recent common ancestor (tMRCA) of the current Arctic and AL RABVs emerged in the 1830s and evolved independently after diversification. Population demographic analysis indicated that the viruses experienced gradual growth followed by a sudden decrease in its population size from the mid-1980s to approximately 2000.Genetic flow patterns among the regions reveal a high geographic correlation in AL RABVs transmission. Discrete phylogeography suggests that the geographic origin of the AL RABVs was in east Russia in approximately the 1830s. The ancestral AL RABV then diversified and immigrated to the countries in Northeast Asia, while the viruses in South Asia were dispersed to the neighboring regions from India. The N and G genes of RABVs in both clades sustained high levels of purifying selection, and the positive selection sites were mainly found on the C-terminus of the G gene.
Conclusions
The current AL RABVs circulating in South and North Asia evolved and dispersed independently.
