OBJECTIVETo study the epidemiology and etiologic characteristics of a Dengue fever outbreak in Fuzhou from the beginning of September to the end of October in 2004 in order to understand the source of infection.

METHODSData on descriptive epidemiology was collected to study the characteristics and related factors to the epidemic. Dengue virus was isolated through the use of C6/36 cell line while viral serotypes were identified by indirect immunofluorecent assay with type-specific monoclonal antibody. The sources of infection were traced by nucleotide sequencing.

RESULTSDuring the epidemic, 93 cases occured consistently with the region entomoplily growth and decay. The viruses of 6 strains isolated from 10 patients' blood specimens were identified as dengue virus type 1. Phylogenetic evidence suggested that the viral isolate had high genetic relation with the isolates from Kampuchea (DENV-1/KHM/2001; GenBank Accession No. L0904278).

CONCLUSIONThe epidemic was caused by introduction of patients migrating into Fuzhou.

OBJECTIVETo discuss the efficacy of Qingkailing soft capsules in treating acute fever, and the relationship between symptoms-effect and time effect.

METHODQingkailing soft capsules was taken orally, 4 times a day, 1.6 g each time. Shuanghuanglian kou fu liquid was taken as control. 129 patients with acute upper respiratory tract infection were recruited.

RESULTThere were 73.34% of patients cured by Qingkailing soft capsules and 43.59% cured by Shuanghuanglian kou fu liquid. The efficacy of the former was better than that of the latter (P < 0.05). The efficacy of Qingkailing soft capsules in treating Fengrexing was better than that in Fenghanxing (P < 0.05). The efficacy of Qingkailing soft capsules in reducing rapid pulse and adding moderate pulse was more remarkable than Shuanghuanglian kou fu liquid (P < 0.05). Taking Qingkailing soft capsules seldom induced mild gastrointestinal disturbance.

CONCLUSIONQingkailing soft capsules showed good result in the treatment of acute upper respiratory tract infection with less adverse effect.

Objective To understand the current status and relevant factors influencing the duration of breastfeeding in rural areas in China.Methods Children under two years old were selected as subjects from the study on "Physical growth among the under 7-years-old children from the rural areas of ten provinces in China in 2006".Kaplan-Meier method was used to estimate the survival curves and Cox multivariate stepwise regression was used to identify the relevant factors on the duration of breastfeeding.Results Median of the duration for breastfeeding was 12 months in rural areas of 10 provinces in China.Results of this study suggested that factors as sex,birth order,areas of residency,nationality,initiation of formula,parents' education levels,maternal services and famliy income were correlated with the duration of breastfeeding.Conclusion Duration of breastfeeding among rural children under 2-years of age was short in the 10 provinces of China.Factors as level of education,residential areas and family income of the parents as well as sex of the chilaren were correlated with the duration of breastfeeding.Intervention program should be implemented to improve the current status on breastfeeding.

Objective: To compare the prognosis of transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valve (BAV) or tricuspid aortic valve (TAV) stenosis. Methods: This was a retrospective study. Patients with symptomatic severe aortic stenosis, who underwent TAVR with follow-up time more than one year in Guangdong Provincial People's Hospital from April 2016 to August 2018, were included. According to aortic CT angiography, the patients were divided into BAV group and TAV group. The primary endpoint was the composite event of all-cause death and stroke, and the secondary endpoints were TAVR-related complications. Incidence of clinical endpoints and parameters derived from echocardiography were compared between the groups, and Kaplan-Meier survival analysis was used to compare the composite event between the two groups. Results: A total of 49 patients were included. The age was (73.6±6.3) years, and 25(51.0%) were male. There were 32 patients in BAV group and 17 in TAV group, the follow-up time was 466 (390, 664) days. The incidence of composite endpoint of death and stroke at one year were comparable in BAV and TAV groups (6.3% (2/32) vs. 5.9% (1/17), P=1.00). Kaplan-Meier curves also showed a similar risk of the composite endpoint(HR=1.03，95%CI 0.09-11.24，Log-rank P=0.98) between two groups. The incidence of all-cause death, stroke, myocardial infarction, severe bleeding, major vascular complications, new-onset atrial fibrillation or atrial flutter, and permanent pacemaker implantation were all similar between the two groups(all P>0.05), and there was no acute kidney injury (stage 2 or 3) in both groups. Echocardiographic parameters at one year were similar between the two groups (all P>0.05). Conclusions: The midterm prognosis of TAVR in patients with BAV and TAV stenosis is similar. Clinical trials of large sample size with long-term follow-up are warranted to verify our findings.

Objective: To compare the safety and efficacy of different anticoagulants in patients with indications for anticoagulation after transcatheter aortic valve replacement (TAVR). Methods: This is a retrospective study. Patients who underwent TAVR from April 2016 to February 2022 in Guangdong Provincial People's Hospital and had indications for anticoagulation were included and divided into two groups according to the type of anticoagulants, i.e. non-vitamin K antagonist oral anticoagulant (NOAC) and warfarin, and patients were followed up for 30 days. The primary endpoint was the combination of death, stroke, myocardial infarction, valve thrombosis, intracardiac thrombosis and major bleeding. The incidence of endpoints was compared between two groups, and multivariate logistic regression analysis was applied to adjust the bias of potential confounders. Results: A total of 80 patients were included. Mean age was (74.4±7.1) years, 43 (53.8%) were male. Forty-nine (61.3%) patients used NOAC, 31 used warfarin, and major indication for anticoagulants was atrial fibrillation (76/80, 95.0%). The adjusted risks of the primary endpoint (OR=0.23, 95%CI 0.06-0.94, P=0.040) of NOAC were lower than that of warfarin, mainly driven by a lower risk of major bleeding (OR=0.19, 95%CI 0.04-0.92, P=0.039). Conclusions: The short-term outcome of NOAC is better than that of warfarin in patients with indications for anticoagulation after TAVR. Randomized controlled trials of large sample size with long-term follow-up are needed to further testify this finding.
