Objective To explore the application effect of home care on the basis of temperament combined with social competence in preschool children with bronchial asthma.Methods A total of 100 preschool children outpatients with bronchial asthma who came to our hospital from January 1 to February 28,2013 were selected with the method of convenience sampling and were randomly divided into observed group and control group with 50 cases in each group.Cases of the observed group were divided into ordinary,middle,and strengthen subgroups according to temperament and social competence.The control group and the ordinary subgroup received routine care interventions,and the other subgroups were given corresponding enhanced care measures.The attack rate of asthma,medical care,quality of life and lung function during one year follow-up were observed and compared between the two groups.Results Within the first six months of follow-up,patients in observed group got better control in acute attacks than the control group [(2.3±0.4) times vs.(3.4±0.3) times,x2=5.710,P＜0.05)].The percentage of forced expiratory volume in the first second and Pediatric Asthma Quality of Life Questionnaire scores in observed group were significantly higher than the control group one years later [(86.9±4.6)％ vs.(85.5±3.8)％ and (90.1±7.5) vs.(76.5±8.0),P＜0.05].Conclusions The application of temperament type combined with social competence showed a good practical value in home care for asthma preschoolers.

Objective:To understand the current situation of human resources in the hemodialysis centers of different levels of hospitals in Beijing, and to provide reference data for themedical institutions at all levels to adjust the related human resources programs.Methods:Based on the self-designed questionnaire, the basic situation of 123 hemodialysis centers and the allocation of human resources of doctors, nurses and engineers in medical institutions of Beijing were investigated and analyzed.Results:Each nurse in hemodialysis center was responsible for (4.98± 0.74) hemodialysis patients at the same time in each treatment shift. The specialized nurses accounted for 23.32% of the total registered nurses. The ratio of engineers to dialysis machines was 1∶25.76. The proportion of doctors, nurses and engineers with intermediate professional titles or above was 82.47%, 33.08% and 29.81% respectively. The proportion of doctors with graduate education or above was 51.13%. The proportion of nurses and engineers with bachelor degree or above was 56.12% and 51.56% respectively. The differences in the professional titles and the highest academic qualifications of the employees (doctors, nurses and engineers) between tertiary hospitals and non-tertiary hospitals were statistically significant ( P < 0.05). Conclusion:The number of personnel in Beijing hemodialysis centers is basically in a similar proportion, but there are some differences between the hemodialysis centers of tertiary hospitals and those of non-tertiary hospitals in terms of age composition, working years, professional titles and educational background. It is necessary to optimize the allocation of human resources in hemodialysis centers of different levels of hospitals, further strengthen the training of professional talents and the cooperation of multidisciplinary teams, to promote the sustainable development of medical service quality.

Objective To obtain the molecular epidemiology of human Parechovirus (HPeV)infections m children with central nervous system (CNS)-related disease and sepsis,as well as understand the pathogenic properties of HPeV infections by detecting HPeV in cerebrospinal fluid (CSF) and blood samples.Methods From January to December in the year of 2009,a total of 359enterovirus-negative specimens including 210 CSF and 149 blood samples were collected from 328children ＜14 years of age who were hospitalized for CNS-related disease and sepsis at Children's Hospital,Fudan University,Shanghai,China.HPeV was detected by nested reverse transcription polymerase chain reaction (RT-PCR),and then directly genotyped by sequencing nested RT-PCR product of VP3/VP1 region.Ninty-nine blood samples from healthy children were collected as controls during the same period.Results Twenty-seven children (8.2％) were HPeV positive in 328 children.HPeV infections were found in all age groups of children and the highest frequency was seen in children ＜3 months old (18.2％,12/66).HPeV was detected in several months,with the peak in December (18.8％,9/48).Of all the positive samples,20 were genotyped successfully and identified to be HPeV1.No HPeV infections were found in blood of healthy controls.ConclusionsHPeV is the pathogen of CNS infections and sepsis in children.HPeV screening should be enrolled in the routine virus testing in specimens obtained from children.HPeV1 is the prevalent type in children in the year of 2009 in Shanghai.

Objective To establish a HPLC method for the determination of galuteolin in Qingyan buccal tablets.Methods A Phenomenex luna C18 column served as stationary phase and the mobile phase was acetonitrile-0.5 %glacial acetic acid,gradient elution with the flow rate of 1 mL?min-1.The column temperature was 25 ℃and detection wavelength was 350 nm.Results A good linearity of galuteolin was in the range of 0.077 12 ?g～0.771 2 ?g and r=0.999 6.The average recovery of galuteolin was 101.35 %and RSD=1.58 %.Conclusion This method is simple,sensitive,accurate,and will provide evidence for the determination of galuteolin in compound preparations.

Objective To investigate susceptibility and antibacterial activity of cationic porphyfin derivative mediated photodynamic antimicrobial chemotherapy (CPD-PACT) against Pseudomonas aeruginosa,to provide experimental evidence for its high efficiency antibacterial activity.Methods The impacts of culture environments on minimum inhibitory concentration (MIC) were measured by double dilution method.The formation of inhibition zone was determined by diffusion plate method.The postantibiotic effect was analyzed by colony forming units.The viability and morphology of Pseudomonas aeruginosa were observed by confocal laser scanning microscopy (CLSM).Results The inoculum size of bacterial had a certain effect on the MIC.The MIC values increased as the pH of medium rose.When the calf serum content of culture medium increased,the MIC rose in light reaction and dropped in dark reaction.The diameter of inhibition zone mainly depended on the laser energy density,but not the concentration of photosensitizer.Though CPD possessed strong antimicrobial activity and persistent suppression on bacterial growth,the surviving Pseudomonas aeruginosa would soon continue to proliferate after PACT.The fluorescence images captured by CLSM showed that CPD-PACT could destroy the membrane integrity,leak the cytoplasmic component,decrease the bacterial activity and finally lead Pseudomonas aeruginosa to death.Conclusions CPD has strong inhibitory activity and obvious postantibiotic effect on Pseudomonas aeruginosa,which is suitable to be developed as an drug candidate for PACT.

Objective To investigate the dynamic characteristic of molecular epidemiology of group A Rotavirus (RV) by analyzing viral genotypes,disease seasonality,and the patients' age distribution,so that to provide theoretical basis for preyention and control of RV diarrhea in children.MethodsA total of 380 RV antigen positive samples were selected from 5176 stool specimens collected from ＜5 year-old patients with acute diarrhea who were admitted to Children's Hospital of Fudan University during January 2006 to December 2008. Multiplex nested reverse transcription polymerase chain reaction (RT-PCR) was used to analyze the RV genotypes.ResultsDuring 2006-2008,the incidence of RV related diarrhea peaked from October to December and about 96.8％ of all RV episodes occurred in patients younger than 3 years old,The predominant genotype was G3 which accounted for 58.4％ (222/380),G9 was an emerging genotype with the prevalence rate as high as 10.8％ (41/380).G1 and G2 types were rarely found during the three years.Infections with both G3 and G9 were the major mixed genotype G infection. Genotype P [8] was predominant with the prevalence rates of 64.6％ (53/82) and 46.8％ (58/124) in 2006 and 2008,respectively,whereasgenotype P[4] was predominant in 2007 (38,5％,67/174).P[6] and P[9] were found as minor types.The major mixed genotype P infection were genotype P[4] and P[8]. The proportion of undetermined genotype G and genotype P strains tended to increasing during 2006-2008.Genotype P [8]G3 was the major RV strain (20.5％) in Shanghai during 2006-2008 and the other prevalent genotypes included P[4]G3 and P[m]G3.Conclusion The infection of group A RV in Shanghai presents some new molecular epidemiology characteristics during 2006-2008,such as switch of predominant genotypes and diversification of prevalent genotypes.

Objective To investigate the miss rate of adenoma with colonoscopy and assess the features and risk factors for missed diagnosis.Methods Patients with colorectal adenoma received a second colonoscopy within 120 days after adenoma was detected and removed on the initial colonoscopy.The findings of two colonoscopies were reviewed and analyzed.The features of adenoma (including size, location, shape, number and pathology) , clinical characteristics of patients (including age, sex, reasons of colonoscopy, history of diverticular disease, history of abdominal or pelvic surgery and colonoscopy with sedation) and endoscopists were recorded.Miss rate and features of different types of missed adenoma were analyzed.We also assessed the effects of adenoma features, patients' characteristics and endoscopists on missed diagnosis of adenoma.Results Adenoma missed diagnosis was found in 271 patients out of 809 recruited subjects (33% ).A total of 425 adenomas were missed out of 2134 (20% ) adenomas detected by repeated colonoscopy.A large diameter was associated with a decrease in the miss rate for adenoma (P < 0.01).Conversely , sessile or flat shape (P < 0.01) , locations at sigmoid, hepatic flexure, cecum and ascending colonic ( P < 0.05) were significantly associated with a higher miss rate of adenoma, as was the number of adenomas (P <0.01).A higher adenoma missed diagnosis rate was observed in beginner colonoscopists, as compared with experienced ones (P < 0.01).Conclusion A marked miss rate of adenoma exists on colonoscopy, which is significantly associated with the size, shape, location and number of adenomas and endoscopists.

Objective To compare the molecular epidemic characteristics of human astrovirus (HAstV) between outpatient and hospitalized children with acute diarrhea,and to investigate the relationship between HAstY infection and diarrhea in children.Methods A total of 298 cases were randomly collected from hospitalized children from January 2008 to December 2010 in Children's Hospital of Fudan University,and 360 specimens were collected from outpatients with acute diarrhea from August 2010 to July 2011.Reverse transcriptase polymerase chain reaction (RT-PCR) was used to detect rotavirus (RV),human calicivirus (HuCV),HAstV and human adenovirus (HAdV).H AstV genotype was determined by gene sequencing and phylogenetic analysis.Results Epidemiology of HAstV in hospitalized children was as follows:among the included 298 samples,HAstV was detected in 27.2％ (81/298) of the patients,compared with 33.9％ (42/124),33.8％ (25/74) and 14.0％ (14/100),respectively from 2008 to 2010.HAstV diarrhea occurred throughout the year and peaked in January,March,and April.95.1％ (77/81) of the infected children were 0-35 months old.All the episodes of HAstV were mixed with other diarrhea virus infection.Molecular epidemiology of HAstV in outpatient children with diarrhea was as follows:the overall incidence of HAstV was 1.9 ％ among the 360 cases (7/360).The seasonal distribution of HAstV's gastroenteritis showed a peak in November.All the outpatient children were 0-35 months old.Three cases were single infection with HAstV and the others were coinfection with RV (3 cases) or HAdV (1 case).All of the detected HAstV,either in inpatients or outpatients,belonged to HAstV-1.Conclusions The detection rate of HAstV in hospitalized children is significantly higher than that in outpatients.Most HAstV infections in hospitalized children are ascribed to nosocomial infections.Most episodes of HAstV infection were accompanied with other diarrhea viruses infection.HAstY single infection is seen in outpatient children while the detection rate is very low,implying that HAstV co-infection with other viruses plays a main role in diarrhea in most instances.

Objective To explore the status of glucocorticoid application in patients with systemic lupus erythematosus (SLE) in China.Methods Epidemiological survey was used.The SLE patients who met the 1997 classification criteria of American College of Rheumatology were enrolled.The usage of glucocorticoid and related adverse reactions were recorded and analyzed.Results A total of 400 SLE patients were enrolled,including 35 men and 365 women.The average age was (37.4 ± 14.0) years old,and the average duration of disease was (6.7 ± 5.8) years.There were 310 patients using glucocorticoid as maintenance.Sixty-one percent (n =244) patients started using medium dose (prednisone 30-＜ 60 mg/d) as the initial treatment of glucocorticoid,which lasted for (37 ± 11) days.The time of drug duration in patients with low dose prednisone (7.5-＜30 mg/d)and high dose (60-100 mg/d) was(92 ± 20)and (17 ± 3) days respectively (P ＜ 0.05 between 3 groups).However,patients receiving different initial dosage were of no discrepancy in the maintenance therapy.During maintenance,even though 51.0％ (n =158) patients were on prednisone 2.5-5 mg/d,the duration of drug use in ＞ 5-10 mg/d groupwas longer [(29.9 ± 3.3) months].Patients with involvement of internal organs had a higher tendency to use 60-100 mg/d prednisone or pulse-dose therapy in the initial treatment,nevertheless these two groups had no difference of maintenance dosage.Among all 400 patients,62 patients withdrew glucocorticoid,including 17 patients with disease remission (4.3％),44 by self-withdrawal and one with adverse reaction.Conclusion In China,the medium dosage of glucocorticoid is the most common initial treatment in patients with SLE.Prednisone 2.5-5 mg/d was the most common choicefor maintenance therapy.Currently,the proportion of glucocorticoid withdrawal remains low in SLE patients achieving remission.
