To identify the genotype and analyze the molecular characteristics of dengue virus strain SZ0524 isolated from serum samples of patients with early stage of dengue fever in Shenzhen in 2005 so as to explore its possible origin. The C6/36 cell line was cultivated with virus strain SZ0524 and its suspension was harvested. The type of isolated virus strain was determined by RT-semi-nested PCR and fluorescent PCR. E gene of isolated virus strain was amplified by RT-PCR and sequenced. Homology and phylogenetic tree of E gene of this dengue virus with the strains isolated from other areas were constructed. This SZ0524 strain was further identified by fluorescent PCR, and confirmed to be the type 4 virus after obtaining the 392bp band with type 4 specific primers. The homology of nucleotide sequence of E gene of SZ0524 strain with the standard type 4 dengue virus H241 strain were 99.7%, but the homology with the standard dengue virus 1,2,3 in the same fragment were 57.0%, 59.2% and 56.2% respectively. Analysis of the phylogenetic tree indicated that SZ0524 was more close to D4-73NIID and D4-61NIID strain, next to H241 strain, and they lied in the same branch of phylogenetic tree. The isolated dengue virus type 4 belonged to genotype Ⅰand the SZ0524 strain was proved to be dengue virus type 4 in the molecular level. Combined with epidemiology information, it is suggested that this case can be classified as an imported case and the SZ0524 strain may be transferred from the southeast asian region.

Encephalomyocarditis virus (EMCV) ,named JZ1202 ,was isolated from domesticated boar in Henan ,China . We performed the full-length genome sequencing and molecular characteristic analysis of the isolated strain .Results showed that the full-genome sequence of EMCV JZ1202 generated a sequence of 7 735 bp in length ,and had 81 .2%-99 .9% nucleotide identity with other reference strains from different animals ,but 99 .4% with Chinese reference from pig .The phylogenetic tree was constructed based on the full-length genome;ORF and VP1 gene sequences identified EMCV was divided into G1 ,G2 and G3 groups ;the strain JZ1202 belongs to G1 with other Chinese reference strains .Results identified that the EMCV infection could cause severe clinical symptoms in domesticated boar .Big regional differences exist in EMCV and the transmission is limit-ed in a range of area .However ,cross infection and prevalence of EMCV disease between domesticated boar and mice might ex-ist .Mutation of some amino acid may occurred in EMCV infected domesticated boar .

Objective To investigate the prevalence and associated factors of fecal incontinence (FI) and urinary incontinence (UI) in postpartum Chinese women.Methods Questionnaires about FI and UI symptoms were completed via telephone interviews conducted within six months after delivery.Multi-variant Logistic analysis was applied for relation between delivery mode and FI or UI.Results (1) Two thousand and twelve postpartum women were admitted into this study,among which 14 (0.7％) had FI within 6 months after delivery.Logistic regression analysis showed that FI was significantly associated with forceps delivery (OR =20.09,95 ％ CI:3.64-110.90,P =0.000),and mediolateral episiotomy (OR=6.11,95％ CI:1.29-28.80,P=0.024).(2) Among the 2012 women,the prevalence of UI,stress urinary incontinence (SUI),urgent urinary incontinence (UUI)and mixed urinary incontinence (MUD was 10.04％ (n=202),8.15％ (n=164),0.94％ (n=19)and 0.94 ％ (n =19),respectively.Logistic regression analysis found that SUI prevalence was related to maternal age (OR =1.07,95％ CI:1.04-1.11,P =0.000),maternal weight before delivery (OR=1.04,95％ CI:1.02-1.06,P=0.001),neonatal head circumference (OR=1.20,95％ CI:1.05-1.39,P =0.010),mediolateral episiotomy (OR =4.96,95 ％ CI:3.05-8.07,P =0.0005 ),spontaneous vaginal delivery (OR=5.22,95％ CI:2.53-10.76,P=0.000) and forceps delivery (OR=9.20,95％ CI:4.07-20.79,P=0.000).UUI was related to maternal weight before delivery (OR=1.51,95％ CI:1.12-2.05,P=0.008).MUI was related to maternal weight before delivery (OR=1.06,95％ CI:1.00-1.11,P=0.049),duration of second stage of labor (OR=1.01,95％ CI:1.00-1.03,P =0.010),mediolateral episiotomy (OR =7.76,95％ CI:1.42-42.52,P=0.017) and forceps delivery (OR=15.21,95％ CI:1.61-143.44,P=0.018).(3) The prevalence of SUI was higher at 4 days and 42 days after delivery (7.95％ and 9.10％).Conclusions (1) F1 and UI prevalence is lower in this study than in other reports.(2) Vaginal delivery is a risk factor for women's FI and UI,especially forceps delivery and mediolateral episiotomy.(3) Maternal age,pre-delivery weight,newborn head circumference,spontaneous vaginal delivery,forceps delivery and mediolateral episiotomy might increase the risk of UI.

Objective To investigate the awareness of the negative emotions on the physical rehabilitation and psychological treatment of family members of stroke patients in Gansu. Methods 1100 stroke patients from 10 hospitals of different levels in Gansu were surveyed. Results Family members who thought negative emotions can affect the recovery of limb function accounted for 77.17%, and who thought psychological treatment was needed accounted for 83.46%. Conclusion Family members of stroke patients think that negative emotions affect the recovery of limb function and psychological treatment is needed.

Objective To investigate the knowledge about risk factors for stroke in stroke patients. Methods 1043 stroke patients in 10 hospitals were investigated with self-designed questionnaire. Results The rate of awareness of risk factors for stroke was: hypertension 61.55%, hyperlipidemia 40.27%, drinking 32.21%, smoking 30.11%, diabetes mellitus 28.67%, heart disease 23.11%. 6.42% knew all the 6 risk factors, and 20.13% did not know any risk factor. The rate of awareness of diabetes mellitus was different among various aged groups (P<0.01), and the rate of awareness of hypertension, hyperlipidemia, and diabetes mellitus increased with the years of education. Conclusion The stroke patients know less about the common risk factors for stroke, who need more health education.

Objective To investigate the knowledge of stroke risk factors in the families of patients with stroke. Methods 1100 family members of stroke patients hospitalized in 10 hospitals of various levels in Gansu were investigated with self-designed questionnaire. Results Most families knew that the hypertension was a risk factor for stroke, and there was no significant difference among ages. 7.32% of the families knew all the 6 common risk factors for stroke, and 14.23% knew none of them. Hypertension, hyperlipidemia, diabetes as the risk factors for stroke was known most in the families finished higher education, and different with the education levels. Heart disease, smoking, consumption of alcohol as risk factors for stroke was known poorly whatever the careers of the families. Conclusion The families of patients with stroke know less about common risk factors for stroke in Gansu.

ObjectiveTo investigate the effect of integrated psychotherapy on activities of daily living (ADL) in patients with post-stroke depression. Methods60 stroke patients were divided into 2 groups: the treatment group and the control group, each including 30 cases. Both groups were treated with routine medicine and rehabilitation, while the treatment group was also treated with psychological approaches in addition. Before and 4 and 12 weeks after treatment, all the patients were assessed with the Zung Self-rating Depression Scale (SDS) and the modified Barthel Index (MBI). ResultsThere was no significant difference between these 2 groups in all the assessment parameters before treatment. The scores of SDS and MBI improved more in treatment group than in control group (P<0.05) 4 and 12 weeks after treatment. ConclusionThe integrate psychotherapy is effective on ADL in patients with post-stroke depression.

Objective To understand the awareness of early symptoms of stroke patients in Gansu. Methods 1100 stroke patients in neurology and neurosurgery departments in 10 hospitals of different levels in Gansu in 2010 were surveyed by questionnaire. Results The awareness rate of early symptoms of stroke was generally low in all age groups. Conclusion Stroke patients were lack of awareness of early symptoms in Gansu, we should step up publicity efforts to enable more patients to receive early treatment and reduce morbidity and mortality.

Objective To investigate the awareness of knowledge about stroke rehabilitation in medical professionals in Gansu.
