OBJECTIVE To survey the current situation of disinfection and supply rooms in 34 hospitals of Hubei Province under the Committee of Hubei Distinfection.METHODS On the basis of certain references,an questionaire was designed to survey on site.RESULTS All 34 hospitals were taken disperse control mode of disinfection;the education was not good enough;most of the disinfection and supply rooms covered limited space,without meeting the standards of Ministry of Health.The rate of equipement usage was low;the working spheres were narrow.CONCLUSIONS There is not any control mode of disinfection and supply rooms in these 34 hospitals;if working staff and equipment are improved,the working spheres can be broaden.it should be transferred to the centralized control mode of disinfection.

Objective To investigate the predictive value of heart rate variability to,and its correlation with ventricular arrhythmias in patients with structural heart disease.Methods 24 hours ambulatory electrocardiogram monitoring was administered during March 2012 and October 2013,and standard deviation of the NN interval (SDNN) in the time-domain analysis and sympathetic/vagal ratio in the frequency domain analysis were collected and retrospectively analyzed in 300 patients.Results The incidence rate of ventricular arrhythmias was higher in patients with structural heart disease in SDNN ＜100 ms group than in control group [4.1％ (3/74) vs.39.5％ (45/114),P＜0.01].The sympathetic/vagal ratio was significantly higher in group with structural heart disease and ventricular arrhythmia than in control group(19.9 ±2.3 vs.10.1 ±1.7,P＜0.01)The time-domain index SDNN was negatively correlated with the frequency domain index (sympathetic/vagal ratio) (r=-0.819,P ＜0.01).Conclusions SDNN ＜100ms and the increased sympathetic/vagal ratio can be considered as the predictors of ventricular arrhythmias in patients with structural heart disease.

AIM: To investigate the possible use of anti-FGF-2 nanobody for the treatment of pathological neovascularization. METHODS: SD rats were divided into a sham operation group, a control group (3 mm diameter circular filter paper soaked with 1 mol/L NaOH solution was applied to the central part of the cornea of rats for 30 s to prepare the rat model of alkali-burn angiogenesis) and a treatment group (treated with a drop of 3 mg/mL anti-FGF-2 nanobody 7 days after the operation. Repeat application 3x/day for 14 days). Corneal angiogenesis was measured by stereoscopic microscopy and CD31 immunohistochemical staining. The mRNA and protein expression levels of VEGF and FGF-2 were detected by quantitative fluorescence PCR (qPCR), enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry.RESULTS: (1) Blood vessel: The area of the treatment group was significantly reduced compared with the model group, and the vascular lumen was narrower (P<0.05). The difference was the most significant after 14 days of drug intervention; (2) Expression level of FGF-2 mRNA and protein: the model group had similar results to the treatment group (P>0.05); (3) Expression levels of VEGF mRNA and protein: The treatment group was significantly higher than the model group (P<0.05). In addition, the expression of VEGF also increased significantly in the continuous administration of the sham operation group. CONCLUSION: Anti-FGF-2 nanobody can be used for the treatment of angiogenesis. However, the expressions of VEGF will compensatorily increase after blocking FGF-2 in normal or pathological rats.
