Regulatory mechanisms and therapeutic potential of microglial inhibitors in neuropathic pain and morphine tolerance / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Microglia are important cells involved in the regulation of neuropathic pain (NPP) and morphine tolerance. Information on their plasticity and polarity has been elucidated after determining their physiological structure, but there is still much to learn about the role of this type of cell in NPP and morphine tolerance. Microglia mediate multiple functions in health and disease by controlling damage in the central nervous system (CNS) and endogenous immune responses to disease. Microglial activation can result in altered opioid system activity, and NPP is characterized by resistance to morphine. Here we investigate the regulatory mechanisms of microglia and review the potential of microglial inhibitors for modulating NPP and morphine tolerance. Targeted inhibition of glial activation is a clinically promising approach to the treatment of NPP and the prevention of morphine tolerance. Finally, we suggest directions for future research on microglial inhibitors.

Risk factors which were associated with heroin use during the methadone maintenancetreatment among 1301 patients in 9 cities of China / 中华流行病学杂志

Objective To determine the proportion of heroin use among patients who were involved in community-based methadone maintenance treatment (MMT) program and to identify the risk factors associated with heroin use. Methods This study was conducted in 9 MMT clinics within 3 provinces. Thirteen hundred and one patients who met the study criteria were selected from each of the five groups with different dosages of methadone users. An administrative questionnaire was applied to explore the demographics,drug abuse-related behaviors and MMT services received by the clients,etc. The prevalence of depression and anxiety among the clients were also collected by SAS and SDS. Urine samples were collected as a biological marker to indicate if heroin had been used. Results Of the 1301 patients,76.2% were males. The mean age was (34.6±6.5) years while 71.7% had an education level of primary school or below. The average daily dosage of methadone was (48.1±29.4) mg and self-satisfied evaluation score on treatment was 8.6. On average,27.7% urine samples showed positive opiate evidence. Marital status,employment status,treatment retention,self-satisfied evaluation score on dosage and dropout history were found to be significantly associatedwith heroin use,while gender,education level and dosage had no significant association with heroin use. It seemed that risk factors that associated with heroin use were different from areas to areas. Conclusion High quality MMT clinic services,high self-satisfied score,longer treatment retention and low dropout rate seemed to have the effects of reducing the risk of ongoing heroin abuse under the methadone maintenance treatment program.

Influence of glucose-insulin-potassium on the levels of inflammatory cytokines and prognosis of MODS in the scalded rats / 中华烧伤杂志

<p><b>OBJECTIVE</b>To evaluate the influence of glucose-insulin-potassium treatment (GIK) on the levels of inflammatory cytokines in the scalded rats with MODS.</p><p><b>METHODS</b>One hundred and twenty Sprague Dawley rats were inflicted with 30% TBSA full-thickness scalding, and MODS model was reproduced with intraperitoneal injection of endotoxin following burn injury. Then the rats were randomly divided into GIK, glucose (G) and control (C) groups, with 40 rats in each group. The serum contents of glucose, lactate acid, TNF-alpha, NO and IL-6 of the rats in the three groups were determined during 1 to 7 PSD, and the mortality rate within 7 PSD was observed.</p><p><b>RESULTS</b>The serum contents of glucose, lactate acid, TNF-alpha, NO and IL-6 of the rats in the GIK group were obviously lower than those in the other two groups during 1 to 7 PSD (P < 0.01), and reached the lowest level at 6 to 7 PSD (TNF-alpha: 2.37 +/- 0.54 microg/L; IL-6: 0.28 +/- 0.17 microg/L; NO: 29 +/- 9 micromol/L). The content of glucose and lactate acid in G group were obviously higher than those in control group (P < 0.01), but the contents of TNF-alpha, IL-6 and NO content were similar between these two groups (P > 0.05). The mortality in GIK group within 7 PSD was 20.0%, which was evidently lower than that in G (37.5%) and C (47.5%) groups (P < 0.05), while that between G and C groups was similar (P > 0.05).</p><p><b>CONCLUSION</b>The administration of GIK might ameliorate sepsis by reducing the levels of inflammatory cytokine after burns and endotoxin challenge.</p>

Effects of total body irradiation injury on the participation of dermal fibroblasts in tissue repair / 生理学报

Wound combined with total body irradiation (TBI) injury results in impairment of tissue repair and delayed processes of healing, so it has been considered as an important and representative model of impaired wound healing, but the mechanism is not fully clarified. Fibroblasts in wound are the most important cells participating in tissue repair, whereas its radiosensitivity is not high. To understand whether TBI injury has direct damaging effects on fibroblasts in wound, fibroblasts in wound combined with TBI injury and in wound of simple incision injury were isolated and cultured, and parameters associated with tissue repair were determined. The results showed that the abilities of proliferation, attachment and adhesion of fibroblasts isolated from wounds combined with TBI injury significantly decreased as compared with those of simple incision injury, nevertheless, apoptotic ratio of fibroblasts isolated from wounds combined with TBI injury increased significantly. These data suggest that TBI injury may cause direct damaging effects on fibroblasts in wounds, which might be one of the dominant reasons for impairment of wound healing when it is combined with TBI injury.
