      Abstract:

          ObjectiveTo evaluate the difference in the configuration and quantity of biofilms in dental unit water lines (DUWL) before and after disinfected with sodium hypochlorite solution. MethodsThe samples of biofilms from DUWL supplied with 10 separate water sources were collected and the microorganisms were quantified after incubated for 48h, and the configuration of biofilms were observed with confocal laser scanning microscope (CLSM) and scanning electronic microscope (SEM). The sodium hypochlorite at concentration of 525 mg/L was used for disinfection of DUWL. ResultsThe number of bacteria in biofilms at the baseline was 1.7×103CFU/cm2 before disinfection and 0 CFU/cm2 after disinfection with sodium hypochlorite solution, there was significant difference between the two (t=12.03,P=0.02) . CLSM and SEM showed that before disinfection, biofilm existed in the inner wall of DUWL,and bacilli and cocci distributed in the matrix; after disinfection, the configuration of biofilms, particularly fencelike structures were destroyed, but matrix was still existed. ConclusionDUWL has been contaminated heavily with a number of microbes, and the inner walls of DUWL is covered with biofilm, which is composed of millions of bacteria. The high concentration of microbes in DUWL is bringing the high risk of cross infection to both dental professionals and patients. Sodium hypochlorite at the concentration of 525 mg/L may be used as a disinfection solution for DUWL with separate water source.

      Abstract:

      ObjectiveTo explore the influence of adefovir dipivoxil (ADV) therapy on the cellular immunity by observing the levels of interferonγ(IFNγ), interleukin4 (IL4) and their relationship with HBV DNA loads in patients with HBeAgpositive chronic hepatitis B at different time before and after treatment. MethodsSera of 30 patients before ADV therapy and 16 weeks ,52 weeks and 132 weeks after ADV therapy respectively were collected in this study. There were 14 complete response cases(group A),16 incomplete response cases(group B). Sera of 10 healthy people were chosen as control group(group C). Levels of IFNγ and IL4 were detected with enzymelinked immunosorbent assay; HBV DNA loads were detected by ROCHE COBAS AMPLICOR HBV MONITOR, lower limit was 103 copy/mL.ResultsThe average IFNγ level in group A was significantly higher than that of group B(P<0.05)and C(P<0.05), there was no significant difference between group B and C(P>0.05);The level of IL4 of group A decreased after treatment while group B didn’t. HBV DNA loads of all groups had no significant correlation with IFNγ and IL4 levels before treatment, but dropped obviously at 16th week after treatment; and the increased level of IFNγ in group A was significantly higher than that of group B(P<0.05); IL4 levels in group A decreased gradually, but didn’t decreased obviously in group B.ConclusionCellular immune response of patients with hepatitis B was resumed to some extent after ADV treatment. The resumption level was positively related with the decreased level of HBV DNA load.

      Abstract:

      ObjectiveTo investigate the clinical diagnostic value of sandwich cup collecting bacteria and smear method (sandwich cup method) in the detection of acidfast bacilli.MethodsFrom July to December 2008 , 1 782 sputum samples (including 642 morning sputum and 1 140 random sputum) were collected from people who were suspected to have pulmonary tuberculosis at tuberculosis prevention and treatment departments in 4 counties (cities) of Hunan Province. Each sample was dealt with sandwich cup method and improved Lowenstein Jensen(LJ) culture, respectively, the results were analyzed.ResultsThe positive rate of LJ culture and sandwich cup method was 26.64%(171/642) and 23.52% (151/642) in morning sputum, respectively, there was significant difference between the two(χ2=4.56,P=0.04); The positive rate of LJ culture and sandwich cup method was 23.33%(266/1 140) and 18.07% (206/1 140) in random sputum respectively , there was significant difference between the two(χ2=34.60,P=0.00). The positive rate of sandwich cup method in morning sputum was significantly higher than that in random sputum(χ2=7.62, P=0.01), while the positive rate of LJ culture in morning and random sputum showed no statistical difference (χ2=2.42, P=0.12).ConclusionThe positive rate of sandwich cup method is lower than LJ culture in detecting acidfast bacilli, but the former is simple, timesaving and easy to carry out quality control, and is worth popularizing in clinic. The positive rate of sandwich cup method in morning sputum is high, so morning sputum should be kept to detect acidfast bacilli clinically.

      Abstract:

      传染病是当今世界范围内引起人类死亡的重要原因,人类正面临着与传染病斗争的新形势。新传染病的出现、老传染病的复燃、病原体对抗菌药物耐药性的增加,构成了对人类健康的巨大威胁,使临床工作和高等医学教学面临新的挑战,已引起国际医学界的极大关注。2003年发生在我国及东南亚各国的严重急性呼吸综合征(SARS)暴发流行,近年来引起全球恐慌的禽流感疫情及2009年全球暴发的甲型H1N1新型流感流行再次警示人们应高度重视“新”传染病的出现和“老”传染病的死灰复燃。

      Abstract:

      重患者静脉给药的有效途径,在疾病治疗中起着非常重要的作用。按照美国疾病预防控制中心(CDC) 1996年和2002年《预防血管内导管相关血流感染指南》对导管的分型,中心静脉导管包括非隧道式导管、隧道式导管、皮下埋置式输液管、经外周穿刺中心静脉导管、血液透析导管等。血管内导管已成为一种临床应用非常广泛的医疗用品,同时也引起了并非少见的各种机械性、血栓性或感染性的并发症。在这些并发症中,血流感染是最致命的。在危重症患者中,若并发血流感染,则归因死亡率可能高达35%[1]。
      美国CDC认可洗必泰是中心静脉导管穿刺时的首选皮肤消毒剂[2]。同时国内近年来对洗必泰的临床使用也给予了高度关注,但对其作用特点、安全性能和临床应用的研究介绍较少,本文就此对洗必泰消毒剂作如下综述。
