RESUMO
As the major means of outpatient payment for basic medical insurance (the insurance for short) relies on fee-for-service, it tends to encourage unreasonable growth of medical expenses. Based on the principal-agent theory, this paper analyzed the principal-agent relationship between the insurance handling agencies and the hospitals designated by the insurance, and constructed a benefit game model of outpatient payment methods and the supporting supervision game model. This practice aims to explore the optimal and balanced benefit of the insurance payment methods and supporting supervision mechanism, and provide decision support for promoting the reform of medical insurance outpatient payment in China. The analysis results of the benefit game model of payment methods showed that a system mixing the post-payment and pre-payment could optimize and maximize the total benefits and interests of all the stakeholders within the system. Specifically, the practice recommended was a mixed payment integrating ambulatory-payment-classification, fee-for-service and global-budget-payment. The analysis of the supporting regulatory game model found that the factors that must be considered to ensure the expected utility of the above mixed payment mode as follows: the gap between the unreasonable income obtained by the hospital by out-of-control charging and the reward obtained by under-control charging, the size of the penalty after the unreasonable income of the hospital was discovered, the size of the regulatory cost and the loss of benefits of the government and the insured group. It is suggested to adopt the mixed payment method mainly based on the ambulatory-payment-classification supported by fee-for-service and global-budget. At the same time, medical insurance agencies can improve their supervision mechanism from such aspects as perfecting penalties, reducing supervision costs, leveraging government administrative power and advocating public supervision.
RESUMO
Objective@#To understand the mortality and influencing factors on injecting drug users (IDUs) with HIV/AIDS, in Guizhou province, 1996-2015.@*Methods@#A retrospective cohort study was conducted on IDUs with HIV/AIDS that were reported through national comprehensive HIV/AIDS information system, in Guizhou province during 1996-2015. Cox proportional hazard regression model was used to analyze the influencing factors on the mortality of HIV/AIDS.@*Results@#A total of 3 958 cases of IDUs with HIV/AIDS were recruited in this study, with all-cause mortality rate of 44.01% (1 742/3 958) and total mortality rate of 7.80/100 person-years, respectively. The median survival time between diagnosis and death was 8.08 years. Mortality rate was 3.57/100 person-years in the group receiving antiretroviral therapy (ART). The mortality appeared to be 4.08/100 person-years in the group who were on methadone maintenance treatment (MMT). Data from the multiple regression analysis indicated that factors of gender, ethnicity, age when HIV/AIDS diagnosis was made, CD4+T lymphocyte (CD4) count at the first testing, ART and MMT were significantly associated with deaths among these people. The risk of death in females was 0.82 times (95%CI: 0.69-0.98) higher than that in males. The risk of deaths among the ethnic minority subjects was 1.39 times (95%CI: 1.21-1.60) higher than that of the Hans. The risk of death appeared to be 2.44 times higher (95%CI: 1.07-5.56) in the over-50-year of age group than in the <20 year-old group, when HIV/AIDS was diagnosed for the first time. The risk of death in CD4 ≥500/μl group in the first time was 0.27 times (95%CI: 0.22-0.32) more than CD4 <200/μl group in the firs time. The risk of death in cases who were treated with ART or MMT was 2.83 times (95%CI: 2.45-3.26) and 1.35 times (95%CI: 1.15-1.59) higher than those who did not receive any treatment, respectively.@*Conclusion@#Higher risks on death seemed to be related to the following factors: being male, older age at the time of diagnosis, lower CD4 at diagnosis, not on ART or MMT among the IDUs with HIV/AIDS in Guizhou province, between 1996-2015.
RESUMO
OBJECTIVE To investigate the effect and its mechanism of laminaria japonica polysaccharides(LJP) on human laryngeal carcinoma cell Tu212 growth. METHODS The laryngeal squamous cell Tu212 in logarithmic growth phase were treated by laminaria japonica polysaccharides(80, 160, 320 μg/ml) and cisplatin(1.8 mg/L). The MTT assay was used to evaluate cell growth inhibition rate after 24h, 48h and 72h. The flow cytometry with PI staining were used to estimate cell cycle distribution after 48h. The fluorescent microscopy was used to estimate cell apoptosis after 48h. The western blot was used to evaluate the expressions of Cyclin B1 and Bcl-2. RESULTS The cell proliferation was inhibited by cellular LJP in a dose and time dependent manner. Tu212 cells proliferation were stopped at the G2/M phase treated with LJP after 48h. Cell apoptosis was observed clearly by f luorescent microscope after 48h. The expressions of Cyclin B1 and Bcl-2 were suppressed significantly treated with LJP after 48 h. All of the differences were significant(P <0.05). CONCLUSION LJP has inhibitive effects on the Tu212 cells, this mechanism was probably through inhibition of the proliferation and promotion of the apoptosis.

Primitive neuroectodermal tumor (PNET) is a small round cell malignancies, normally confined to the chest wall and soft tissues of children and young adults, and reports of this tumor existing in nasal cavity are scarce. We herein present a case of nasal PNET. A 35-year-old male patient presented with a chief complaint of stuffy nose was diagnosed with a primary nasal pPNET by the clinical, microscopic, immunohistochemical features. Since these tumors are highly aggressive and patient prognosis is typically very poor, early diagnosis, immediate surgical resection and re-resection if possible, early radiotherapy and chemotherapy and close follow-up are required. We also review literatures on pPNET.

OBJECTIVE@#Systematic reviews and Meta-analysis were conducted to assess the efficacy and security of adenoidectomy for the treatment of otitis media with effusion in children.@*METHOD@#Based on the principles and methods of Cochrane systematic reviews, literature was searched in PubMed, Medline, Elisevier, Ovid, CBM, CNKI, VIP and Wanfang datebases. Randomized controlled trials about treatment of otitis media with effusion in children using adenoidectomy were included. Meta-analysis was performed for the result of homogeneous studies using RevMan 5.2 software.@*RESULT@#Adenoidectomy (combined with myringotomy or puncture) was superior to non-surgical (combined with myringotomy or puncture) treatment in reducing the incidence of acute otitis media and removing the middle ear effusion. Adenoidectomy combined with tympanostomy tube was superior to tympanostomy tube alone in the removal of the middle ear effusion and improvement of hearing level. Three trials described some postoperative complications including haemorrhage, incipient malignant hyperthermia, postoperative pneumonia and velopharyngeal insufficiency.@*CONCLUSION@#Our research shows a benefit of adenoidectomy in the removal of middle ear effusion in children with OME. Adenoidectomy combined with tympanostomy tube was superior to tympanostomy tube alone in improving hearing level. At present, there is no evidence of serious postoperative complications after adenoidectomy.

Allergic airway diseases have been identified as chronic inflammatory diseases of respiratory membranes, characterized by infiltration of many inflammatory cells, especially eosinophils. The expression of CCR3 is abundant on the cell surface of eosinophils. Increased accumulation of CCR3-driven inflammatory cells is thought to favor the development of allergy. In this review, we survey the properties of CCR3 and its ligands and highlight the roles of CCR3 signaling in allergic airway diseases.
