Objective To discuss the surgical method and efficacy of adult Dandy-Walker syndrome ( DWS) through retrospective anal-ysis and literature review .Methods There were 3 cases of adult DWS in our hospital from August 2010 to August 2011.One case of them was given posterior cranial fossa cyst peritoneal shunt , and the surgery adopted ordinary high voltage shunt .Case 2 was given left side of the lateral ventricle peritoneal shunt , and the surgery adopted ordinary high voltage shunt .Case 3 was given posterior cranial fossa cyst peritoneal shunt combined with left side of the lateral ventricle peritoneal shunt , and the surgery adopted double-end high voltage shunt .The two ends of the shunt were respectively linked with the diverter valve and abdominal cavity drainage tube through T -branch pipe .Results Among the 3 patients, there was 1 case failed to ease the headache symptoms , and it was relieved one month later .The preoperative symptoms of the oth-er 2 cases disappeared immediately after the surgery .During the 4 years of follow-up,preoperative symptoms of the 3 patients disappeared , and there was no positive signs .Conclusion For adult patients with symptomatic DWS ,shunt surgery can eliminate symptoms ,relieve the tension of the posterior fossa cyst ,achieve good curative effect , and there was no surgical complication .

Objective To study the prevalence,risk factors of overactive bladder (OAB) in middle-aged and senior residents in Zhengzhou China.Methods A randomized,community-based,crosssectional study was performed on 10 160 residents aged 40 or older in urban area of Zhengzhou by using a stratified system sampling approach.A questionnaire including the subjects' basic information,previous history,present history,the Chinese overactive bladder symptom score (OABSS) was filled on site.The diagnostic criteria for OAB was 'an urgency score for Question 3 of 2 or more,and an OABSS of 3 or more'.Chisquare test was used to determine the differences of prevalence between genders,age groups,BMI and people with and without diabetes mellitus (DM).A pairwise comparison was conducted between different age,BMI group by using Bonferroni method.Results A total of 10 160 residents were investigated and finally 9805 (96.5％) were qualified for final statistical analysis.The mean age was (57.9 ± 9.7) years.The overall prevalence of OAB was 2.1％ (209/9805),of which,with OABdry 1.0％,and OABwet 1.1％.Male subjects were more likely suffered from OAB than female,with 2.7％ (84/3129) versus 1.9％ (125/6676).The prevalence of OAB in both male and female increased with age.There was no significant difference in the prevalence of male and female before the age of 60 years (1.2％ versus 1.4％,P ＞ 0.05) and more common in men than in women after the age of 60 years (4.6％ versus 2.6％,P ＜ 0.05).The prevalence of the subjects with DM was significantly higher than those without DM (P ＜ 0.05).The subjects with BMIs of 30 or more were nore likely to have OAB (3.2％ versus 1.8％,P ＜ 0.05).Conclusions The prevalence of OAB increases with advancing age.The prevalence of male is higher than female after the age of 60 years.The diabetics and obese people are more likely to have OAB.

Ebolavirus can cause hemorrhagic fever in humans with a mortality rate of 50%-90%. Currently, no approved vaccines and antiviral therapies are available. Human TIM1 is considered as an attachment factor for EBOV, enhancing viral infection through interaction with PS located on the viral envelope. However, reasons underlying the preferable usage of hTIM-1, but not other PS binding receptors by filovirus, remain unknown. We firstly demonstrated a direct interaction between hTIM-1 and EBOV GP in vitro and determined the crystal structures of the Ig V domains of hTIM-1 and hTIM-4. The binding region in hTIM-1 to EBOV GP was mapped by chimeras and mutation assays, which were designed based on structural analysis. Pseudovirion infection assays performed using hTIM-1 and its homologs as well as point mutants verified the location of the GP binding site and the importance of EBOV GP-hTIM-1 interaction in EBOV cellular entry.

Objective: To study the relationship between morphological characteristics, grading, diagnosis and prognosis in phyllodes tumors (PT) of the breast. Methods: A retrospective study was carried out on 83 PTs diagnosed between 1999 and 2003 that were classified semi-quantitatively according to the WHO recommendation. Follow-up data was available for some cases, and Cox regression analysis was used to evaluate factors affecting metastasis and recurrence. Results: All cases were classified into the benign (57.8%), borderline (28.9%) and malignant (13.3%). The overall recurrence rate for the 72 cases with follow-up data was 20.8% (15/72), and was 17.5% (7/40) in benign, 22.7% (5/22) in borderline and 3/10 in malignant PT, respectively, with no significant difference (P>0.05). The median interval between the initial diagnosis and the first recurrence was 24 months. Lung or bone metastases occurred in 1/22 borderline and 3/10 malignant PT patients 5 years post-surgery. The mitotic count and the degree of stromal cell atypia were significantly correlated with recurrence (P=0.001 and P=0.006). Multivariate analysis showed that severe stromal cell atypia was an independent predictor of recurrence-free survival in PT [HR=6.40 (95% CI=1.378 to 29.732), P=0.018]. Conclusions Each parameter in the histological grading of PT may have different prognostic value, and markedly increased mitotic count and were predictive of relapse.

To explore the application of humanistic care in children's fever clinics,the children's fever clinics of Guangzhou Women and Children's Medical Center conducted relevant research using narrative medicine as a guiding concept.This paper elaborated on the medical humanistic dilemmas and narrative care needs in children's fever clinics,and focused on exploring the practice paths of narrative medicine in pediatric with Chinese characteristics from five dimensions,including the cultivation of nursing staff's abilities of professional narrative and humanistic care,the establishment of health lectures featuring narrative patient education,the alleviation of medical anxiety for children and their families,related support of narrative nursing,and caring services.The aim was to improve the narrative care ability of nurses in children's fever clinics,develop methods for pediatric patients that can eliminate the fear of seeking medical treatment,and protect children's physical and mental health.A carrier of care,support,and emotional expression can be provided for parents.The foundation for nursing staff to achieve professional growth through narrative reflection can be laid.Thus,it can assist in establishing a life narrative community relationship between doctors and patients,and jointly explore the meaning of life.
