RESUMO
Objective To investigate the epidemiological and pathogenic characteristics of viral diarrhea in Minhang District, Shanghai. Methods Random sampling on diarrhea was conducted in intestinal outpatient departments of 2 sentinel hospitals according to a certain sampling interval in Minhang District，Shanghai from 2014 to 2020. Real time PCR technology was used to detect Rotavirus, Norovirus, adenovirus, Astrovirus and Sapovirus in fecal samples. Results A total of 646 out of 1 839 stool specimenswere tested positive, and the positive rate was 35.13%.Five pathogenic viruses were detected , mostly norovirus (421 cases, 65.17%) followed by rotavirus (151 cases, 23.37%).The positive rate of norovirus was higher in the age group of 20- 69 years, and the positive rate of Rotavirus was higher in the age group of 0- 9 years. Conclusions Norovirus and rotavirus accounted for the majority of reported infection diarrhea cases in MinhangDistrict of Shanghai from 2014 to 2020, with significant seasonal peaks. Tailored prevention and control measures should be carried out, particularly in risk seasons.
RESUMO
@#Objective To investigation the effects of Phlebitis Mixture, a Chinese medicine, on the complications after endovenous laser treatment for varicose great saphenous veins. Methods 62 patients after endovenous laser treatment for varicose great saphenous veins were divided into the treatment group and the control group. The treatment group was administered with Phlebitis Mixture. The control group was treated with convention therapy. Results The incidence of very effective was 62.5% in the treatment group and 40.33% in the control group respectively (P<0.05). More in the treatment group released from pain, local heat, etc. than in the control (P<0.05). Conclusion The Phlebitis Mixture is helpful for the recovery from endovenous laser treatment for varicose veins.
RESUMO
Objective To explore the rat's abdominal pressure decending law by applying quantitative analytical technique.Methods Intra-abdominal hypertension rat model is made by Nitrogen aeroperitonerm.Nitrogen is exhausted the abdomen at fixed quantity and fixed time cell.MP-100A-CE type physiological monitor is used to record the changes of intra-abdominal pressure.The pressure numerical average value at different time are recorded,and the volume of Nitrogen exhausted and the pressure of intra-abdominal scatterplot are drawed.Regression analysis is used to study the functional relation between them.Results The regularity of the intra-abdominal pressure decrease was as follows:In Intra-abdominal Hypertension condition,discharge little Nitrogen could cause intra-abdominal pressure decrease greatly.Then the rate of decay is slowed.Intra-abdominal pressure(y)and Nitrogen in the abdomen(y)present decrement exponential function relation,the formula is:y=36.3190?0.9769x,and the pressure-volume index is-0.01.Conclusion Regularity of intra-abdominal pressure decengding is exponential function between intra-abdominal pressure and Nitrogen volume exhausted from the abdomen.
RESUMO
Objective: To investigate the protective effect of Xuesaitong(total saponins of sanchi) on lower extremity ischemical reperfusion injury.Methods: To observe PBN-spin bulky adducts signal of lower extremity ischemical reperfusion of rabbit by using electron spin resonance technology and electron spin resonance promoter N-tert-butyl-2-phenylnitrone(PBN).Results: The signal intensity is correlated with time,compared with ischemia for 2 hours,the signal intensity of ischemia for 4 hours increased apparently.Xuesaitong would quench PBN-spin bulky adducts signal significantly.Conclusion: Xuesaitong have protective effect on lower extremity ischemia-reperfusion injury.
