??Objective    To discuss the influence of basic periodontal therapy on the level of IL-8?? IL-10 in serum and gingival crevicular fluid in patients who have chronic periodontitis complicated by coronary heart disease. Methods     A total of 65 cases of patients with chronic periodontitis complicated by coronary heart disease were selected and divided into two groups randomly??Group A of 35 patients who received the basic periodontal therapy and cardiac medical treatment??Group B of 30 patients who received cardiological treatment only. Then??select 25 patient who had developed chronic severe periodontitis with non-systematic disease to establish group C and give them the basic periodontal therapy only. Observe the changes of the IL-8??IL-10 levels in serum and gingival crevicular fluid and the periodontal infection indexes??BI??PD??. Results    The results showed that after three months of basic periodontal therapy the periodontal clinical indices of both group A and group C became better and the IL-8 level obviously reduced??while the IL-10 level obviously increased. There was no obvious difference between group A and group B in each examination index before the therapy. After three months??we found that the periodontal infection index??SBI PD??of group A was obviously better than group B. Compared to group B??the IL-8 level of group A obviously reduced??and the IL-10 level obviously increased. The difference was statistically significant??P < 0.05??. Conclusion    The basic periodontal therapy can effectively improve periodontal conditions of the patients with chronic periodontal diseases??and reduce the risk of breaking the normal cardiovascular function.     

8周基础军训对入伍新兵红细胞及其相关指标的影响

目的探讨8周基础军训(basic military training,BMT)对入伍新兵血像中红细胞及其相关指标的影响,为指导科学的军事训练提供参考。方法数据来自新疆边防部队2015年度入伍的50名男性新兵,分别在BMT前后测定并记录受试新兵的红细胞计数、血红蛋白浓度及血清铁蛋白等。结果经过8周的BMT,新兵血液中血红蛋白浓度、红细胞计数及血清铁蛋白均显著下降(P0.05,P0.01)。结论 8周BMT可能导致入伍新兵发生运动性贫血,铁缺乏可能是其主要原因。     

正念减压疗法对妊娠呕吐妇女负性情绪和生活质量的影响

目的 探析正念减压疗法对妊娠呕吐妇女负性情绪和生活质量的影响。 方法 将2017年5月-2018年5月在我院治疗的90例妊娠呕吐妇女纳入本研究,采用数字表法随机分成研究组和对照组,每组各45例。对照组接受宣教,研究组在对照组上实施正念减压疗法。分别于入组时、干预4周和干预8周采用焦虑自评量表(self-rating anxiety scale,SAS)、抑郁自评量表(self-rating depression scale,SDS)、生活质量综合评定问卷(generic quality of life inventory-74,GQOLI-74)进行评估,比较2组妊娠呕吐妇女负性情绪和生活质量。 结果 2组SAS、SDS评分及生活质量综合评定问卷总分在组间效应、时间效应及交互效应上差异具统计学意义。 结论 妊娠呕吐妇女进行正念减压疗法,能够显著减轻妊娠呕吐妇女负性情绪和提高生活质量,值得在临床上广泛应用。

目的探讨T细胞非特异性活化在CNS脱髓鞘性疾病中的作用。方法分离实验性自身免疫性脑脊髓炎(EAE)易感性BALB/c小鼠外周血单个核细胞(PBMC),采用体外细胞培养方法在体外与碱性髓鞘蛋白(MBP)共培养,测定培养上清液中IFN-γ、NO水平。结果经MBP刺激的PBMC产生IFN-γ[(43.83±6.06)pg/mL]和NO[(180.76±20.75)μmol/L]明显增加,与对照组产生的IFN-γ[(28.52±2.18)pg/mL]和NO[(95.61±13.09)μmol/L]相比差异有统计学意义(P<0.01)。结论在CNS脱髓鞘性疾病发病过程中,活化的T细胞、单核细胞等分泌致炎细胞因子和其他有害物质增多。     

加强基层微生物室生物安全防护

近年来，尤其是2003年发生的SARS疫情以及新加坡、台北、北京陆续发生的SARS冠状病毒实验室感染传播事件，使实验室的安全管理隐患变成了巨大的现实危害。这给各类微生物或生物医学实验室的生物安全防护敲响了警钟。作为基层微生物室工作人员每天都在接触含有不同致病性的微生物标本，其中也不排除含有风险级别较高、传播途径不明的微生物样品，但是由于基层微生物实验室的结构和设施、安全操作规范、安全设备、防护措施以及试验人员的安全防护意识却相对薄弱，因此为了试验人员、实验室及生态环境安伞，消除实验室生物安全隐患，卫生行政部门应重视基层微生物室的生物安全问题。     

Basic fibroblast growth factor mRNA, bFGF peptide and FGF receptor in epiretinal membranes of intraocular proliferative disorders (PVR and PDR)

Basic fibroblast growth factor (bFGF) has been shown to be involved in epiretinal membrane formation in proliferative vitreoretinal disorders. However, up to now, little knowledge exists, as to the actual cellular source of this potent mitogen.We examined 20 epiretinal membranes from patients with proliferative diabetic retinopathy (PDR) (n = 12) and proliferative vitreoretinopathy (PVR) (n = 8) for the presence of bFGF peptide, fibroblast growth factor receptor-1 (FGFR-1) and bFGF messenger ribonucleic acid (mRNA).Using a specific antibody, we detected bFGF peptide in most (8/10) examined PDR membranes and in all (8/8) PVR membranes. Moreover, we found positive staining for the corresponding receptor.Local production of bFGF in epiretinal membranes was confirmed by nonisotopic in situ hybridisation for bFGF mRNA in some (4/7) examined PDR membranes and some (3/4) examined PVR membranes. All membranes which contained bFGF mRNA were also positive for bFGF peptide.In conclusion, bFGF is produced and stored in epiretinal membranes. Together with the corresponding receptor, bFGF may play a role in the auto- and paracrine control of the proliferative processes at the vitroretinal interface.Abbreviations aFGF acidic fibroblast growth factor - bFGF basic fibroblast growth factor - FGFR-1 fibroblast growth factor receptor-1 - mRNA messenger ribonucleic acid
