ABSTRACT

Objective To evaluate hospital acquired infection control using the risk assessment method of hazard vulnerability analysis (HVA). Methods The HVA risk assessment method was used to screen out two hospital-level priority improvement projects in hospital acquired infection management in 2016, and assess the relative risk of the risk factors,for selective intervention according to the"20% -80% principle". 2015 was set as baseline survey, while the first and second half of 2016 as the outcome evaluation stage. The comparison of the count data was performed using the χ2test. Results Baseline survey of hand hygiene found the compliance rate and high-touch surface cleaning pass rate as 64.4% and 57.0% respectively. The first stage of evaluation found the rate as 69.0% and 73.7% respectively, while in the second stage rate was 72.9% and 82.4% respectively. These differences were statistically significant (P<0.001). Baseline survey found the incidence of hospital acquired infection and surgical site infection as 1.26% and 0.29% respectively, while the figures in the stage of evaluation were 1.07% and 0.22% respectively,figures being statistically significant (P<0.05). Conclusions The HVA risk management proves significant for the prevention and control of hospital acquired infection, as it can identify and assess risk factors of hospital acquired infection,for better risk control.

ABSTRACT

Objective To evaluate the effect of targeted monitoring and comprehensive intervention measures on reducing the occurrence of catheter-associated urinary tract infection(CAUTI)in patients in non-intensive care unit(Non-ICU).Methods In quarter 4 of 2015,patients with indwelling urinary catheter in clinical departments were conducted a baseline survey(before intervention),risk factors for CAUTI in patients were analyzed,targeted monitoring programmes and comprehensive intervention measures were initiated in 2016(after intervention),incidence of CAUTI before and after intervention was compared.Results After taking intervention measures,hand hygiene compliance rate increased from 78.51%in quarter 4 of 2015 to 92.99%in quarter 3 of 2016 and 90.73%in quarter 4 of 2016(x2=7.342,3.998,respectively,both P<0.05),the correct disposal rate of patients' urinary catheterization system increased from 72.83%in quarter 4 of 2015 to 95.44%in quarter 4 of 2016(x2=30.267,P<0.05).A total of 12 067 patients with indwelling urinary catheter were monitored,incidence of CAUTI dropped from 1.03%(24/23 313)in quarter 4 of 2015(before intervention)to 0.53%(14/26 595)in quarter 4 of 2016(after intervention),difference was statistically significant(x2=4.126,P=0.042).Conclusion Improving the quality of urinary catheterization system in patients with indwelling catheter through targeted monitoring can effectively reduce the incidence of CAUTI in patients in Non-ICU.

ABSTRACT

Objective To investigate the effect and mechanism of decorin (DCN) on invasion of colorectal cancer cell line HCT116 in vitro.Methods Transwell assay was employed to detect the invasion of HCT116 cells;Real-time PCR was used to detect the expression of CD133 and TIMP-2 mRNA of HCT116 cells;Western blot method was used to detect the expression of HIF-1α, CD133 and TIMP-2 protein of HCT116 cells.Results 1) When the concentrations of DCN was 0, 1 and 3 mg/L, under the conditions of normal oxygen and hypoxia, the numbers of invasive cells were (241±46), (168±46), (51±17) fields in each well (P<0.01) and (207±61), (213±64), (156±54), (44±17) fields in each well (P<0.01).2) Under the normoxic conditions, the TIMP-2 mRNA and protein in HCT116 cells were increased by DCN (3 mg/L) (P<0.01), but that of CD133 were not affected.3) DCN (3 mg/L) significantly decreased the expression of HIF-1α/CD133/TIMP-2 protein in HCT116 cells under hypoxia (P<0.01), but had no significant effect on the expression of CD133 mRNA.ConclusionsUnder the conditions of hypoxia and normal oxygen, DCN may function through different mechanisms to inhibit the invasion of colorectal adenocarcinoma cell line HCT116 in vitro.

ABSTRACT

Purpurin is a common component ofRubia cordifolia L. The study on its molecular target was useful for elucidating the therapeutic material basis and action mechanism ofR. cordifolia. HT-29 cells were used in the cell culture. The highly expressed G Protein-coupled Receptor-35 (GPR35) agonist was used as target. The label-free optical biosensor cellular assay was used to investigate the agonist activity ofpurpurin at an endogenous receptor. The results showed thatpurpurin can cause DMR response in HT-29 cells. And the DMR response curve type was consistent with zaprinast. Its EC50 was 6.142± 0.189μmol·L-1. In addition,purpurinhad desensitization effect on GPR35 agonist zaprinast in HT-29 cells. GPR35 agonist ML145 blocked the DMR ofpurpurin. It was concluded thatpurpurinwas the GPR35 agonist.

ABSTRACT

Objective To evaluate application of fist clenching method with shaking hands in venipuncture to elderly angular patients. Methods 360 elderly angular patients were randomly divided into group A and group B with 180 cases in each group. Group A used fist clenching method with shaking hands, group B adopted traditional fist clenching method in venipuncture. Pain degree and one-time success rate of two groups were compared. Results One-time success rate of group A in venipuncture was obviously higher than group B, while pain degree of group A was less than group B. Conclusions Fist clenching method with shaking hands to elderly angular patients can raise success rate in venipuncture, and reduce pain degree of patients.
