OBJECTIVETo evaluate the diagnostic value of micro-movement sensitive mattress sleep monitoring system (MSMSMS) in children with obstructive sleep apnea hypopnea syndrome.

METHODSSixty-five children with the complaint of sleep disorder were collected and detected by polysomnography and micro-sensitive mattress sleep monitoring system overnight at least seven hours. The date from two instruments were analyzed by computer automatically and then modified by two professional staff double-blind separately. The data about the diagnosis of sleep breath disorder and other sleep physiology information were compared between the two groups.

RESULTSSixty-one cases finished the study finally. The mean age of these children was (7.0 ± 2.7) and the youngest was 3 years old, maximum was 13 years old, male children 46 cases, female patients 15 cases, body mass index (BMI) median [25 quantile; 75 quantile] 16.00 [14.80;17.5]kg/m2. Mean PSG measured apnea hypopnea index (AHI) was 4.50 [2.30;10.15] times/h, and mean MSMSMS AHI was 3.63 [2.56; 6.43] times/h. There was a significant correlation between PSG AHI and AHI by MSMSMS (r = 0.935, P < 0.01). A Bland-Altamplot of PSG AHI and MSMSMS AHI was also used to assess the accuracy of MSMSMS. 95. 1% of the data was fallen in the 95% consistency areas. For AHI--5 times/h and nighttime minimum oxygen < 91% or obstructive apnea index( OAT) > 1 time/h and nighttime minimum oxygen saturation < 91 % as threshold value, the MSMSMS diagnosing sensitivity and specificity were 82.9% and 92.3%. The misdiagnosis rate and missed diagnosis rate were 7.7% and 17.1%.

CONCLUSIONSThe MSMSMS offer a simple and comfortable method to monitor children's sleep. It improves the compliance in the process of sleep monitoring. Besides, as a diagnostic tool in the diagnosis of OSAHS on children has a high credibility in AHI.

Objective:To explore the relation of social adaptability to theory of mind (Tom)and executive function (EF)in Chinese children with autism.Method:Thirty-eight children aged 6.0 -12.9 years and meeting the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition (DSM-IV)criteria for autism were re-cruited.They were assessed with the Children's Adaptive Behavior Rating Scale,Chinese Wechsler Intelligence Scale for Children (C-WISC),Tom test and EF task,then their adaptive quotient (ADQ),intelligence quotient, scores of theory of mind and executive function were obtained.Results:In this sample,the ADQ was (85.4 ± 20.9),the T scores of independent factor,cognitive factor and social self-control factor were separately (40.2 ± 17.3),(43.3 ±15.7)and (42.0 ±16.0).The median total intelligence quotient was (102.1 ±24.0).After con-trolling for age and intelligence quotient,the score of first false belief understanding was positively correlated with social responsibility subsclale score and social self-control factor score (r =0.50,0.45,Ps <0.05).In executive function test,scores of immediate and delayed recall for details of Rey complex figure recall task were negatively correlated with social responsibility subscale score (r =-0.46,-0.47,Ps <0.05).In Stroop tests,the second test time,the forth test time,the forth test error number and alpha numeric connection error number were negatively cor-related with economic activity subscale score (r =-0.63,-0.57,-0.45,-0.57,Ps <0.05).The second test time of Stroop was negatively correlated with the scores of individual choose subscale and social self-control factor (r =-0.46,-0.50,Ps <0.05).Conclusion:It suggests that social adaptability may be related to theory of mind and executive function.The autistic children with better theory of mind and executive function have better social a-daptability.

Objective To investigate the prevalence and risk factors of hyperuricemia (HUA) in rural residents of Gaoyou City,Jiangsu Province.Methods A total of 4504 rural residents were investigated in a cross-sectional study.Questionarre survey and physical examination were used for the stndy.Fatsing venous blood samples were collected for biochemical examination.T-test,chi-square test for multiple-group data comparison and logistic regression analysis were used for statistical analysis.Results The prevalence of HUA was 11.9％,15.7％ in male,which was significantly higher than 8.6％ in the female (P＜0.01),the risks of HUA in male was 1.98 times higher than in female.The average value of serum uric acid in this population was higher than.that of female.The prevalence of HUA in female increased with age.Non-conditional logistic regression analysis showed WHR,Cr,Tg,hypertension were the independent risk factors of male patients with HUA.Age,BMI,Cr,Tg,hypertension were independent risk factors of HUA in female.Conclusion The prevalence of HUA can be affected by age and sex.Weight control,keeping blood pressure and blood lipid profiles in normals levels are important for the prevention of HUA.

Pulmonary arteriovenous malformations (PAVMs) can induce cryptogenic stroke and are also an important cause of stroke in young adults. The risk of ischemic stroke increases with age in patients with PAVMs. Contrast echocardiography can be used for early screening of PAVMs, especially in young patients with cryptogenic stroke. After treatment, patients with PAVMs have a reduced risk of ischemic stroke. This article summarizes the etiology, pathogenesis, diagnosis and treatment of PAVMs by retrieving studies on PAVMs and ischemic stroke, in order to improve the understanding of PAVMs and avoid misdiagnosis and missed diagnosis.

Objective: To learn about the construction and staffing of the school health system in Chinese institutions for disease prevention and control, and to provide basic information for the school health system, team capacity building and work development. Methods: Electronic questionnaire was used to collect the setting and staffing of school health departments (including school health centers and departments/rooms) at the provincial, prefecture and county (district) levels in the centers for disease control and prevention. Statistical analysis was made on the proportion of school health, the number of staff and the characteristics such as age, education, major and working years in the provincial, prefecture and county (district) levels. Results: Among the 3 313 institutions, the proportion of independent school health departments was 10.8%, and those of the provincial, prefecture and county (district) levels were 74.2%, 15.0%, and 9.6%, respectively. Among the institutions with separated department, the average number of staff members was 4.4, while the number of staff was 2.5. The average age of school health workers was 40.4 years old, and the proportion of male and female employees was 45.2% and 54.8%. The proportion of personnel who have been engaged in school health work for less than 5 years on average was as high as 65.1%. The majors of the staff were mainly public health ( 40.4 %), 54.0% of the provincial staff had a master s degree or above, and 47.8% and 58.7% of the staff at the prefecture and county (district) levels were junior college or below respectively.The proportion of provincial level personnel with intermediate and senior titles was 69.6%, and the proportion of municipal and countylevel personnel at the junior level and below was 52.2% and 56.2% respectively. Conclusion The proportion of independent school health departments within centers of disease control and prevention across China was low. There is a serious shortage of school health personnel, and there are problems such as low levels of education and professional titles, especially in county (district) level institutions. It is urgent to strengthen the construction of the school health system of the centers for disease control and prevention in China.

Objective:To systematically evaluate the efficacy and safety of filiform fire needle combined with tacrolimus ointment in the treatment of vitiligo.Methods:The RCTs of combination of filiform fire needle and tacrolimus ointment on the treatment of vitiligo were searched in the Chinese Biomedical Literature Database (CBM), China Knowledge Network Full-text Database (CNKI), Wanfang Full-text Database, VIP and PubMed databases. The studies were selected with the inclusion and exclusion criteria, then data extracted, and the quality of the included studies was evaluated according to Cochrane System Evaluation Manual. Meta-analysis was performed using RevMen 5.3 software.Results:Four studies involving 218 patients were included. After analysis, it was found that the effective rate [ OR=4.42, 95% CI (1.39-14.03), P<0.05)] and the apparent efficiency [ OR=2.89, 95% CI (1.40-5.95), P=0.004] of filiform fire needle combined with tacrolimus ointment were significantly better than that of tacrolimus ointment alone. Adverse reactions werelocal slight redness, pain and itching. None of adverse reactionswas reported. Recurrence occurred in the follow-up of were reported in two studies, which found that the recurrence rate [ OR=0.17, 95% CI (0.04-0.77), P<0.05] in the combined treatment group was significantly lower than that in the control group. Conclusions:The clinical efficacy of filiform fire needle combined with tacrolimus ointment in the treatment of vitiligo is better than that of tacrolimus ointment alone, and the recurrence rate can be reduced without any adverse reactions. However, in view of the limited number, average quality and bias of the included studies, it is suggested to carry out more multi-center, large sample and high quality randomized controlled trials for further verification.

Objective: To understand the current status of main professional work in independent school health departments of Chinese centers for disease control and prevention, so as to provide reference and suggestions for the further development of school health work in China. Methods: Electronic questionnaire was used to collect the basic work of school health, the monitoring work, the intervention action of common diseases and the development of health intervention among students in independent school health departments of centers for disease control and prevention in China. Results: Among the 357 institutions that have set up independent school health departments, the implementation rates of school mental health work, safety emergency and risk avoidance health intervention were low, which were 11.8% and 11.5%, respectively. Relying on the project "national monitoring and intervention of common diseases and health influencing factors of students", the overall implementation of health monitoring in schools nationwide was successful, but the overall implementation rate of students nutritional status monitoring and "healthy parents action" were low, accounting for 44.5% and 24.4%, respectively. At the same time, there were still as many as 27.2% institutions that had not carried out the intervention action for common diseases of students which advocated in the monitoring program. The failure rate of county level institutions was higher than that of provincial level and prefecture level institutions, and the failure rate of the central and western institutions was much higher than that of the eastern institutions; the difference was statistically significant( χ 2=30.1, 41.6, P <0.05). Conclusion We should increase support including policy preference, fund guarantee, technical guidance and so on for the school health work of disease control institutions at the grass roots level and in economically underdeveloped areas, so as to ensure the healthy growth of children and adolescents in all respects.

Objective To explore the structure changes of white matter in the first-episode schizo-phrenic patients with never-medicated(FESZ)and the relationship between facial emotion perception and white matter(WM)integrity.Methods Sixty-three schizophrenic patients and thirty health control subjects underwent diffusion tensor imaging(DTI)scans.Voxel-based analysis was used to compared fractional ani-sotropy(FA)map between the two groups.Correlations were analyzed with pearson relative analysis between impaired facial emotion perception tested by facial emotion categorization(FEC)and severity of symptoms measured by the Positive and Negative Syndrome Scale(PANSS).Results (1)Compared with controls, FESZ patients showed overall decreased FA in WM of the body of left ventral frontal lobe((MNI(x,y,z):-18,26,-4;t=4.43)),right supramarginal gyrus((MNI(x,y,z):32,-50,26;t=4.27)),left middle oc-cipital gyral((MNI(x,y,z):-26,-60,0;t=4.89)),right middle occipital gyral((MNI(x,y,z):28,-70, 14;t=4.18)),left fusiform gyrus((MNI(x,y,z):-40,-50,0;t=3.92)),left cerebellum anterior lobe ((MNI(x,y,z):-32,-56,-28;t=4.57)),right parahippocampa gyrus1((MNI(x,y,z):32,-10,-14;t=4.16)),right parahippocampa gyrus2((MNI(x,y,z):16,-6,-14;t=4.56)),left anterior cingulate ((MNI(x,y,z):-2,4,-6;t=4.41)),left extra-nuclear((MNI(x,y,z):-2,-10,-6;t=4.44)),right thalamus((MNI(x,y,z):10,-10,2;t=4.20)),left thalamus((MNI(x,y,z):-22,-28,12;t=4.01)), and right caudate((MNI(x,y,z):14,12,8;t=4.87)).(2)Compared with controls,the patients with schizo-phrenia showed a higher shift point and a steeper slope than control subjects in FEC.Correlational analysis re-vealed that the negative correlations were found between the slope and negative factor(r=-0.298,P=0.036),between positive factor and the FA value in WM of the right middle occipital gyral(r=-0.322,P=0.023)and the left middle occipital gyral(r=-0.288,P=0.043),and between the FA value in the left cere-bellum anterior lobe and shift point(r=-0.393,P=0.005),but the positive correlation was found between disorganized/concrete factor and the FA value in the right parahippocampal gyrus(r=0.429,P=0.002).Con-clusions There are extensive microstructural abnormalities in WM of patients with FESZ.Disrupted WM in-tegrity in these regions may constitute a potential neural pathological basis for the facial emotion perception impairments in schizophrenia.

OBJECTIVETo establish a canine cell line with p53 gene knockdown by lentivirus- mediated RNA interference (RNAi).

METHODSFour pairs of oligonucleotide sequences of p53 gene were synthesized and cloned into the pGMLV-SC5 RNAi vector. Following confirmation by PCR and DNA sequencing, the recombinant pGMLV-p53 plasmids and packaging mix vectors were packaged into mature lentivirus to infect 293T cells. The supernatant of the infected cells was harvested to infect WRD cells, in which p53 expression was detected using Western blotting and real-time PCR. The lentivirus with the strongest p53⁻ silencing effect was packaged for infecting WRD cells at the optimal multiplicity of infection (MOI) to establish a stably infected cell line (WRD/p53⁻) screened using puromycin.

RESULTSThe lentivirus carrying p53 shRNA was constructed successfully and a virus titer of 1 × 10⁹ TU/ml. The 4 pGMLV-p53 plasmids all produced strong p53 interference affects, and pGMLV- p53A1 with the strongest effect. The stably infected cells line WRD/p53⁻ was established successfully using pGMLV-p53A1 plasmid.

CONCLUSIONThe canine cell line WRD/p53⁻ with stable lentivirus-mediated p53 silencing has been established successfully.
