Objective To analyze the main practices of capitation payment system reform in the case areas and put forward enlightenments and suggestions in this regard. Methods The implementation practices of the case areas were summarized, and descriptive statistical analysis was carried out on the implementation effects. Results By analyzing the effectiveness of the case areas′reform, it was found that the case areas are curbing the excessive growth of medical expenses (for example, outpatient fees per visit of Dingyuan county-level hospitals decreased from 245.11 yuan in 2015 to 218.40 yuan in 2017), increasing the actual compensation ratio of residents ( for example, the actual compensation ratio of Funan increased from 59.80% in 2015 to 63.28% in 2017), forming a medical treatment pattern within the county (for example, out-of-county compensation ratio in Dingyuan decreased from 37.38% in 2015 to 31.13% in 2017), achieving double-way referrals (for example, the number of referrals to superior hospitals of Jimo increased from 98 in 2015 to 328 in 2017), improving the subsidence of quality services, and controlling the risks of medical insurance funds. Conclusions At present, the reform of the case areas has been implemented steadily and achieved results. It is recommended to further improve such aspects as reform coordination, insurance standard setting, incentive mechanism establishment, and leadership to ensure the reform progress.

OBJECTIVETo define the differences in gene expression patterns between glycidyl methacrylate (GMA)-transformed human lung fibroblast cells (2BS cells) and controls.

METHODSThe mRNA differential display polymerase chain reaction (DD-PCR) technique was used. cDNAs were synthesized by reverse transcription and amplified by PCR using 30 primer combinations. After being screened by dot blot analysis, differentially expressed cDNAs were cloned, sequenced and confirmed by Northern blot analysis.

RESULTSEighteen differentially expressed cDNAs were cloned and sequenced, of which 17 were highly homologous to known genes (homology = 89%-100%) and one was an unknown gene. Northern blot analysis confirmed that eight genes encoding human zinc finger protein 217 (ZNF217), mixed-lineage kinase 3 (MLK-3), ribosomal protein (RP) L15, RPL41, RPS 16, TBX3, stanniocalcin 2 (STC2) and mouse ubiquitin conjugating enzyme (UBC), respectively, were up-regulated, and three genes including human transforming growth factor beta inducible gene (Betaig-h3), alpha-1,2-mannosidase 1A2 (MAN 1A2) gene and an unknown gene were down-regulated in the GMA-transformed cells.

CONCLUSIONAnalysis of the potential function of these genes suggest that they may be possibly linked to a variety of cellular processes such as transcription, signal transduction, protein synthesis and growth, and that their differential expression could contribute to the GMA-induced neoplastic transformation.

OBJECTIVETo evaluate the genotoxic and nongenotoxic effects of short-term exposure to glycidyl mathacrylate (GMA) on human lung fibroblast cells (2BS cells) in vitro.

METHODSDNA strand breakage was determined by single cell gel electrophoresis, and DNA ladder formation assay and flow cytometric analysis were carried out to detect apoptic responses of cells to GMA exposure. The HPRT gene mutation assay was used to evaluate the mutagenicity, and the effect of GMA on gap junctional intercellular communication (GJIC) in the exposed cells was examined with the scrape loading/dye transfer technique. The ability of GMA to transform 2BS cells was also tested by an in vitro cell transformation assay.

RESULTSExposure to GMA resulted in a dose-dependent increase in DNA strand breaks but not apoptic responses. GMA was also shown to significantly induce HPRT gene mutations and morphological transformation in 2BS cells in vitro. In contrast, GMA produced a concentration-dependent inhibition of GJIC.

CONCLUSIONSGMA elicits both genotoxic and nongenotoxic effects on 2BS cells in vitro. The induction of DNA damage and gene mutations and inhibition of GJIC by GMA may casually contribute to GMA-induced cell transformation.

The present study aimed to investigate the protective effect and mechanism of hydrogen sulfide donor NaHS administration against gastric mucosal injury induced by gastric ischemia-reperfusion (GI-R) in rats. GI-R injury was induced by clamping the celiac artery of adult male SD rats for 30 min and followed by reperfusion for 1 h. The rats were randomly divided into sham group, GI-R group, NaHS group, glibenclamide group and pinacidil group. Gastric mucosal damage was analyzed with macroscopic injured area, deep damage was assessed with histopathology scores, and the hydrogen sulfide concentration in plasma was determined by colorimetric method. The results showed that pretreatment of NaHS significantly reduced the injured area and deep damage of the gastric mucosa induced by GI-R. However, NaHS did not significantly alter the levels of hydrogen sulfide in plasma 14 d after NaHS administration. The gastric protective effect of NaHS during reperfusion could be attenuated by glibenclamide, an ATP-sensitive potassium channel (K(ATP)) blocker. However, K(ATP) opener pinacidil inhibited the GI-R-induced injury. These results suggest that exogenous hydrogen sulfide plays a protective role against GI-R injury in rats possibly through modulation of K(ATP) channel opening.

Ras is best known for its ability to regulate cell growth, proliferation and differentiation. Mutations in Ras are associated with the abnormal cell proliferation which can result in incidence of all human cancers. Extracellular signal-regulated kinase (ERK) is a downstream effector of Ras and plays important roles in prognosis of tumors. Recently, evidence has gradually accumulated to demonstrate that there are other effectors between Ras and ERK, these proteins interact each other and constitute the thorough Ras/Raf/MEK/ERK signaling pathway. The pathway has profound effects on incidence of esophageal carcinoma and clinical applications of some chemotherapeutic drugs targeting the pathway. Further understanding of the relevant molecular mechanisms of Ras/Raf/MEK/ERK signaling pathway can be helpful for the development of efficient targeting therapeutic approaches which contribute to the treatment of esophageal cancer. In this article, roles of Ras/Raf/MEK/ERK signaling pathway in esophageal carcinoma as well as pharmacological targeting point in the pathway are reviewed.

Objective To explore the characteristics and their influencing factors of economic burden for pneumoconiosis disease,and to provide a baseline to develop the prevention measures and to reduce the economic burden of pneumoconiosis. Methods The retrospective epidemiological method was used to investigate the general information of pneumoconiosis cases,frequency of outpatient and hospitalization per year,medical expenditure. Direct economic loss and its influencing factors of pneumoconiosis patients were analyzed. Results A total of 421 pneumoconiosis cases were investigated. All subjects were male,including 306 inpatients. The average medical expenditures of outpatient and inpatient were 594. 53 ± 336. 23 and 32 266. 06 ± 28 130. 67 Yuan,respectively. The annual average expenditures of outpatient and inpatient were 2 907. 25 and 48 721. 75 Yuan,respectively. In terms of health care costs,the highest proportion of western medicine was 44. 08% ,followed by traditional Chinese medicine(12. 62% ). With an increase in pneumoconiosis stage,the annual frequency of outpatient and hospitalization,as well as total expenditure increased accordingly. The average annual cost of pneumoconiosis inpatient with complications and non - complication inpatient were 55 822. 20 and 23 532. 21 Yuan,respectively. The annual average cost of outpatient with complications and without complications were 4 236. 41 and 882. 31 Yuan, respectively. The expenditures for pneumoconiosis disease with complications among outpatient and inpatient were significantly higher than those of pneumoconiosis patients without complications(P < 0. 05). Conclusion Direct economic loss of pneumoconiosis disease is relatively high. The disease stage and complications of pneumoconiosis are the main factors influencing the direct economic loss of pneumoconiosis.

OBJECTIVETo explore the biomarker of manganese exposure by analyzing the relationship between manganese exposure and concentration in some biomaterials.

METHODSThe air samples were collected through the individual air sample. According to the manganese levels in the air, workers were assigned to control group, low concentration group and high concentration group, and manganese in the hair, urine, serum, blood cell and saliva from different group were measured respectively. The correlations between concentration of external manganese exposure and manganese concentrations in biomaterials, and years of employment and concentrations in biomaterials were analyzed.

RESULTSIn the high concentration group, saliva manganese was 32.17 µg/L, hair manganese was 37.39 mg/kg, urine manganese was 2.50 µg/L, plasma manganese was 29.61 µg/L, blood manganese was 14.49 µg/L, were higher than those in the control group (10.40 µg/L, 1.60 mg/kg, 0.77 µg/L, 10.30 µg/L, 4.56 µg/L respectively) (P < 0.01). The manganese concentration in the saliva was significantly correlated with airborne manganese concentration (r = 0.649, P < 0.01), with the years of employment (r = 0.404, P < 0.01), with the total exposure of manganese (r = 0.342, P < 0.01), with the manganese concentration of plasma (r = 0.303, P < 0.01) and with the manganese concentration in blood cells (r = 0.359, P < 0.01), respectively.

CONCLUSIONSThe concentration of manganese in saliva could work as a biomarker of manganese internal exposure.
