ABSTRACT
Objective@#To investigate an acute gastroenteritis outbreak caused by Norovirus, and to provide evidence for effective school infectious outbreak prevention and control.@*Methods@#In March 2019, basic information of Huzhou Normal University and related data of cases were collected. Epidemiological characteristics were analyzed. Anal swabs of the 10 cases were collected for laboratory detection. Case definitions, specific detection criteria and procedures were based on the Diagnostic Criteria for Infectious Diarrhea (WS 271-2007) and the Technical Guidelines for the Investigation, Prevention and Control of Outbreaks of Norovirus Infection (2015 edition).@*Results@#During March 15 to March 20, a total of 13 (12 girls and 1 boy) confirmed cases were reported, all of them were from the same class, with the incidence rate being 25.00% (1/4) and 37.50% (12/32) in boys and girls, respectively. No significant sex difference was found ( χ 2=2.05， P >0.05). Anal swab specimens of 10 students were collected from laboratory were positive for Norovirus GII and have an identity of 100%.@*Conclusion@#The gastroenteritis outbreak was deduced to be attributed to GII Norovirus infection, which are likely caused by fecal contamination through person to person contact. It is suggested that schools should strengthen knowledge education on the prevention and control of infectious diseases and improve the protection awareness and ability of teachers and students to protect them.
ABSTRACT
OBJECTIVE:To observe clinical efficacy of urinary kallidinogenase in the treatment of acute cerebral watershed in-farct (WSI). METHODS:128 patients with WSI were randomly divided into control group and treatment group,each of the 64 cases. Control group was given Shuxuening 15 ml added into 0.9% Sodium chloride 250 ml,ivgtt,qd;treatment group received urinary kallidinogenase 0.15 PNA added into 0.9% Sodium chloride 100 ml,ivgtt,qd. Both groups were treated for consecutive 14 days. Neurologic impairment score(NIHSS)and clinical efficacy were observed in 2 groups before treatment and 3,7 and 14 days after treatment. The blood specimens were collected after 7 and 14 days treatment,to determine serum levels of TCC. RESULTS:After treatment,NIHSS and total effective rate of treatment group were significantly higher than those of control group,with statis-tical significance(P0.05);7 days af-ter treatment,TCC level of 2 groups increased significantly,to 14 days,and a declive;the treatment group was higher than the control group,with statistical significance (P<0.05). CONCLUSIONS:Urinary kallidinogenase can improve clinical efficacy of WSI significantly,and promote neurologic impairment symptom and TCC levels.
ABSTRACT
Objective To investigate the application value of combination of ambroxol and fluidmicronized ipratropium bromide in full dose and frequency in treating senile refractory pneumonia.Methods From January 2010 to November 2013,84 cases of elderly patients with refractory pneumonia were divided into 3 groups.On the basis of anti-inflammatory and symptomatic treatment,the control group (n=28) received routine sputum suction and normal saline irrigation;the routine dose group (n=28) received the intravenous ambroxol 15 mg twice daily and the inhalation of 2.5 ml of nebulized ipratropium bromide once daily plus treatment in control group while full dose group (n=28) received intravenous ambroxol hydrochloride 30 mg three times a day and the inhalation of 2.5 ml of nebulized ipratropium bromide four times a day.The severity of pulmonary infection was described by clinical pulmonary infection score (CPIS) and C reactive protein (CRP),and therapeutic efficiency was evaluated by clinical symptom remission time,average hospitalization days and effective rate.Results At the 5 day and 10 days after treatment,the CPIS in full dose group was (4.82 ± 1.21) scores and (4.39± 1.03),respectively,C-reactive protein (CRP) was (58.11 ± 11.12) mg/L and (57.57±12.69) mg/L respectively,and these CPIS and CRP values at the 5 day and 10 days were significantly lower than those in the control group (6.10 ± 1.10) scores and (5.36 ± 0.95) scores,(74.50± 12.79)mg/L and (68.46± 13.77) mg/L (all P＜0.05).The above Values were lower as compared with those [(5.43±0.84) and (5.21 ±0.83),(65.11 ±834) mg/L and (59.11± 13.77) mg/L (P＜ 0.05)] in routine dose group.The CPIS and CRP concentration in full dose group and routine dose group were lower at the 10 days than at the 5 days (P＜0.05).Besides,clinical symptom remission time (4.43 ± 1.75) days,average hospitalization duration(26.32 ± 4.92) days in full dose group,clinical symptom remission time (5.68 ± 2.29) day,average hospitalization (32.21 ± 5.63) days in conventional dose group were significantly lower than in the control group (7.79±2.74) and (36.71 ± 11.78) days (P ＜ 0.05).Clinical manifestation,time of remission,and average hospitalization days of the full dose group were also reduced as compared with the conventional dose group (P＜0.05).The efficiency rates in the three groups of control,conventional dose and full dose were 42.9％ (12/28),71.4％ (20/28),92.9％ (26/28),among which the efficiency of full dose group was significantly higher than those of the control group and the conventional dose group,(x2 =16.047,6.788,P＜0.01).The conventional dose group showed a higher efficiency than the control group (x2 =4.667,P ＜ 0.01).Conclusions Combination of ambroxol and fluid-micronized ipratropium bromidet in full dose and frequency for treating senile refractory pneumonia is a useful managemen in the elderly patients.

ABSTRACT
Objective To explore the impact of waist-to-hip ratio (WHR) in type 2 diabetic probands on the phenotype of insulin resistance and β-cell function in normoglycemic first-degree relatives. Methods One hundred and eighty-six type 2 diabetic probands and 489 normoglycemic first-degree relatives were selected from 186 type 2 diabetes core families. 115 first-degree relatives (FDR1 group) of probands with low WHR (1st quartile: <0.86 for males and <0.84 for females) and 106 first-degree relatives (FDR2 group) of probands with high WHR (4th quartile: >0.92 for males and >0.89 for females) were identified to intensively study from 489 normoglycemic first-degree relatives. The homeostasis model assessment of insulin resistance (HOMA-IR) was used to estimate insulin sensitivity, and β-cell function was quantified as the ratio of the incremental insulin to glucose responses over the first 30 min (△I30/△G30) during the oral glucose tolerance test. The latter measure was also adjusted for the assay of insulin sensitivity as it modulated β-cell function (△I,,30>·△G-1,30·HOMA-IR-1). Results The body mass index, the waist circumference and waist-to-height ratio in female first-degree relatives, systolic blood pressure, triglyceride and HOMA-1R were significantly higher in FDR2 group than those in FDR1 group andhigh density lipoprotein cholesterol,△I30/△G30, △I-130·HOMA-IR-1were significantly lower in FDR2 group than those in FDRI group (P < 0.05 or P < 0.O1). The waist circumference and waist-to-height ratio in relatives of probands with low and high WHR were positively correlated with the HOMA-IR. However, the least square regression analysis showed that the slope from regression in FDR2 group were significantly steeper than thatin FDR1 group(both P <0.01). Conclusion The normoglycemic first-degree relatives of the type 2 diabetic probands with high WHR had much more evident phenotype of insulin resistance and decreased β-cell function, and a slight increase in abdominal obesity had a greater impact on insulin resistance.

@# Objective To observe the effects of citalopram and physical therapy on poststroke depression(PSD).Methods72 patients with PSD were randomly divided into medicine group(n=36)and control group(n=36).The patients in the control group were treated only with physical therapy and the patients in the medicine group were treated with Citalopram and physical therapy.All patients were assessed with Zung Self-Rating Depression Scale(ZSDS)and Modified Barthel index(MBI)before and after treatment.ResultsAfter treatment,the Zung score in both groups decreased significantly(P<0.01).Meanwhile,the medicine group showed significantly less depression than the control group(P<0.05).The score of MBI was also significantly increased after treatment(P<0.01)in both group,but there was no significant difference between two groups(P>0.05).ConclusionCitalopram combined with physical therapy is effective on PSD.
ABSTRACT
Objective To explore the effect of spironolactone on vascular remodeling of injuried rabbit artery. Methods 20 male New Zealand rabbits were randomly divided into two groups. The rabbit models of iliac artery angioplasty were set up by BC. After injury, control group was fed with standard forage, and experimental group was fed with standard forage and spironolactone(20mg?kg~ -1?d~ -1). The rabbits were killed four weeks after injury. The injuried segments of iliac artery were removed, and processed for histological and morphological analysis by imumohistochemistry and TD 2000 analysis system of pathology image. Results AUIEM and AUEEM in the experimental group significantly increased as compared with the control group(P0.05). Conclusion Spironolactone could improve vascular remodeling after angioploasty of iliac artery in rabbits.
ABSTRACT
AIM: To investigate the electrophysiological characteristics of ventricular myocyte both in subendocardium and in subepicardium during ischemia. METHODS: Using modified Ferrier's method of ischemic and reperfusion injury in isolated guinea pig right ventricular wall. RESULTS: The transmembranal electric activities in subendocardium and in subepicardium were all significantly abnormal, and it was more significant in subendocardium. CONCLUSION: The alteration degree of ventricular myocyte in subendocardium and in subepicardium during ischemia and early reperfusion was different, and this might be the electrophysiological basis of the vulnerability of the subendocardium.
ABSTRACT
Objective To investigate the protective effect of ascorbic acid on myocardium from ischemia and reperfusion injury and its electrophysiological mechanism. Methods Using modified Ferrier's arrhythmia induced by ischemia and reperfusion injury in isolated guinea pig right ventricular wall. Results Ascorbic acid at 5, 10, 50 and 100μmol/L slightly decrease incidence of ischemia arrhythmia (P ＞ 0. 05). In contrast, ascorbic acid at 10, 50 and 100μmol/L significantly reduced the incidence of arrhythmia during early reperfusion(2～12min) (P ＜ 0. 01 or P ＜ 0. 001). Ascorbic acid at 5～ 100μmol/L didn't reverse the abbrevating of APD of endocardium and epicardium and didn't affect the conduction time in endocardium (P ＞ 0. 05). However, ascorbic acid abbreviated epicardial conduc tion time significantly (P ＜ 0. 05 or P ＜ 0. 01 or P ＜ 0. 001 ). Conclusion The study suggests that ascorbic acid might exert antiarrhythmic effect via alleviating conduction abnormity to avoid transmural reentries during ischemia and early reperfusion.
ABSTRACT
A 54-kDa protein overexpressed by chloroquine-resistant Plasmodium berghei ANKA strain was first reported by us. In this paper, the localization of this protein by immunoelec-tron microscopy is presented. The results showed that the protein was mainly scattered inside the cytoplasm of the early date trophozoites and schizonts of erythrocytic stage of P. berghei ANKA strain , and some of it was also found in cytoplasm of erythrocytes infected with parasites. The protein content was much higher in chloroquine-resistant P. berghei ANKA strain than in chloroquine-sensitive P. berghei ANKA strain, suggesting the importance of this protein in understanding mechanism of chloroquine resistance in malaria parasites .
ABSTRACT
0.05, respectively), but those to noradrenaline (NA: 0.01?mol/L), histamine (His: 3?mol/L), and 5-hydroxytryptamine (5-HT: 0.1?mol/L), significantly reduced (P0.05, respectively). Under atropine or Ani pretreatment, the NA-, His- and 5-HT-elicited contractions in endothelium-denuded aorta were similar to those in endothelium-intact aorta. Conclusion Atropine and Ani can inhibit receptors-mediated constrictions of rabbit aortic vascular smooth muscle cells; the actions are endothelia independent.
