ABSTRACT
ObjectiveTo investigate the current status of knowledge， attitude and practice of nurses in mental health hospitals on the prevention and control of nosocomial infections， and to analyze the influencing factors. MethodsFrom June to August 2020， 402 clinical nurses from 8 mental health hospitals in a city were enrolled using simple random sampling method， and were assessed using a self-compiled knowledge-attitude-practice questionnaire related to the nosocomial infection prevention and control， thereafter， the influencing factors were screened. ResultsThe scores of knowledge， attitude and practice dimensions in relation to the nosocomial infection prevention and control among the nurses were （8.43±1.84）， （76.01±5.70） and （57.42±3.75）， respectively. Univariate analysis showed that the knowledge dimension score demonstrated significant difference among nurses of different types of hospital， grades of hospital， professional titles， education levels， and emphasis degrees of hospital and individual on nosocomial infection （P<0.05 or 0.01）. The attitude dimension scores yielded significant difference among nurses of different types of hospital， position， grades of hospital， and emphasis degrees of hospital and individual on nosocomial infection （P<0.05 or 0.01）. The practice dimension scores manifested significant difference among nurses of different types of hospital， grades of hospital， professional titles， emphasis degrees of hospital and individual on nosocomial infection， and training frequency （P<0.05 or 0.01）. Multiple linear regression analysis showed that professional titles and individual emphasis on nosocomial infection entered the regression model of nurses' knowledge dimension of nosocomial infection prevention and control （P<0.05 or 0.01）. Individual emphasis on nosocomial infection， hospital types and position entered the regression model of attitude dimension （P<0.05 or 0.01）. Individual emphasis on nosocomial infection， hospital types， professional titles， and hospital emphasis on nosocomial infection entered the regression model of practice dimension （P<0.05 or 0.01）. ConclusionNurses in mental health hospital have a positive attitude towards nosocomial infection prevention and control， but their knowledge base needs to be strengthened.
ABSTRACT
Objective To observe the clinical efficacy of Dachaihu decoction in treatment of stroke-associated pneumonia (SAP) in the elderly patients with excess-heat syndrome and acute ischemic stroke (AIS). Methods One hundred elderly patients with excess-heat syndrome and SAP admitted to the Department of Neurology of Tianjin Nankai Hospital from August 2015 to September 2016 were enrolled, and they were divided into a control group and an observation group according to the random number table, 50 cases in each group. Both groups were given conventional neurological treatment, while the observation group additionally received Dachaihu decoction (the ingredients of the decoction: bupleurum 15 g, scutellariae 10 g, pinellia 10 g, fructus aurantii immaturus 15 g, radix paeoniae alba 10 g, rhubarb 5 g, ginger 10 g, jujube 2), and according to the individual's symptoms and signs, the above ingredients can be added and/or subtracted, 1 dose per day, divided into two parts, 1 part taken in the morning and 1 part in the evening orally, 14 days as a therapeutic course. The body temperature recovery time, the duration of antibiotic treatment, the changes of Clinical Pulmonary Infection Score (CPIS) and National Institutes of Health Stroke Scale (NIHSS) score before and after treatment of the two groups were observed and the therapeutic effects in the two groups were evaluated. Results The body temperature recovery time (days: 6.56±2.70 vs. 8.08±3.23) and the duration of antibiotic treatment (days: 8.78±2.80 vs. 10.02±2.90) in the observation group were significantly shorter than those in the control group (both P ＜ 0.05); with the prolongation of treatment, after treatment, the CPIS and NIHSS score were decreased significantly in both groups, reaching the lowest levels on the 14th day, and the degrees of score descent in observation group were more significant than those of the control group (CPIS score: 0.68±0.59 vs. 1.12±0.96, NIHSS score: 6.38±2.31 vs. 7.44±2.74, both P ＜ 0.05); the total effective rate in the observation group was significantly higher than that in the control group [92% (46/50) vs. 76% (38/50), P ＜ 0.05]. Conclusion The therapeutic effect of Dachaihu decoction used for treatment of SAP in elderly patients with excess-heat syndrome is favorably effective and safe.
ABSTRACT
Objective To evaluate the clinical effects of block calculus extraction catheter in the ureteroscopic lasertripsy. Methods Two hundred and thirty patients with ureter calculus were enrolled. Ninety-six patients were treated with block calculus extraction catheter (test group), and 134 patients were treated without block calculus extraction catheter (control group). The patients in 2 groups were treated with holmium laser ureteroscopic lithotripsy of Lumenis PowerSuite60W, and the treatment effectiveness was compared. Results The operation time and primary stone clearance rate in test group were significantly better than those in control group: (23.3 ± 7.4) min vs. (35.6 ± 11.1) min, 98.92%(92/93) vs. 88.89%(112/126), and there were significantly differences (P 0.05). Conclusions The block calculus extraction catheter is very useful and safe in preventing the calculus shift, shortening the operation time and improving the calculus elimination rate .
ABSTRACT
Objective To observe the clinical efficacy of acupuncture plus contralateral needling in treating post-stoke myodystonia. Method Totally 120 patients with post-stroke myodystonia were randomized into group A, B, C and D, 30 in each group. Group A was intervened by yin-reducing and yang-tonifying needling method plus contralateral needling; group B was by ordinary acupuncture plus contralateral needling, group C was by yin-reducing and yang-tonifying needling alone, while group D by ordinary acupuncture. Clinical Spasticity Index (CSI) was observed before and after intervention. Result After treatment, the CSI scores (tendon reflex, muscle tension, episodic spasm scores and total score) were significantly changed in the four groups (P<0.01, P<0.05). The tendon reflex score, muscle tension score and total score in group A were significantly different from that in the other three groups after intervention (P<0.01,P<0.05). There was a significant difference in comparing the episodic spasm score between group A and D after intervention (P<0.01). There were significant differences in comparing the tendon reflex score, muscle tension score and total score between group B and D after intervention (P<0.05). The total score in group C was markedly different from that in group D after intervention (P<0.05). Conclusion Yin-reducing and yang-tonifying needling method plus contralateral needling is an effective method in treating post-stroke myodystonia.
