Objective To investigate the requirment of family rehabilitation training and provide instructions and references to guide parents practising family rehabilitation training for cerebral palsy (CP) children in Shanghai.Methods300 CP children were surveyed with the Requirement Questionnaire of Family Guidance Training Program of Rehabilitation for Cerebral Palsy Children. Then 100 children out of them were selected randomly and a visiting training and guidance of rehabilitation in family was afforded.ResultsAfter providing training and guidance of rehabilitation in family, the requirement of family rehabilitation increased from 41.5% to 92.7% ( P<0.01) and the duration and the times of training were also increased ( P<0.01).ConclusionThe families having CP children in Shanghai don't understand fully about the family rehabilitation. The visiting training and guidance program will be helpful for CP children having complete rehabilitation and coming back to society.

OBJECTIVE: To analyze the impact of extraction and nonextraction in soft tissue profile repair. METHODS: Databases of CNKI, Wanfang, VIP Chinese Periodical Database, CBM, Medline (ovid) and Science direct had been searched for studies of soft tissue profile after orthodontic treatment with and without extractions published in recent decade, with orthodontics, corrective, tooth extraction, soft tissue profile as key words. Hand searching was also done to obtain any further information about the studies. Meta analysis was used to comprehensively quantitatively analyze the upper (lower) lip with esthetic plane and soft tissue plane before and after extraction and nonextraction treatment. According to homogeneity test, fixed effect model and random effect model were adopted to calculate weighted mean difference (WMD) and 95% confidence interval (95% Cl).Revman 5.0 was used for data management. RESULTS: Five studies with 356 patients were included. Homogeneity test showed that lower lip-esthetic line and lower lip-soft tissue line Ⅰ~2 < 50%, without heterogeneity, so fixed effect model was adopted. Upper lip-esthetic line and upper lip-soft tissue line were more than 50%, indicating heterogeneity, so random effect model was adopted. Result of meta-analysis showed that, the WMD value and 95% Cl of lower lip-esthetic line, lower lip-soft tissue line, and upper lip-soft tissue line has statistically significance. CONCLUSION: The extraction treatment significantly decreased the distance of lower lip-esthetic line, lower lip-soft tissue line, and upper lip-soft tissue line.

Objective To study the relationship between personality and defense mechanism of obsessivecompulsive disorder (OCD) patients.Methods Thirty-four OCD patients were tested with Swedish University Scales of Personality(SSP) and defensive style questionnaire( DSQ), and the result was compared with that of thirty-one normal controls.Results The SSP scores of STA,PsTA,SS,E,TI and M of OCD patients were significantly higher than that of normal controls (t = 2.06 ～ 5.10, P ＜ 0.05 ).Comparing with normal controls, OCD patients tended to use immature and intermediate mechanism such as projection, passive aggression, unconscious emerge, phantasy, withdrawl and reaction formation, but less used mature mechanism such as sublimation, suppression and humor (t = -2.27 ～ 6.73, P＜ 0.05 ).All subscales of SSP in OCD patients, excluding SD and D, had positive correlation with total score of immature mechanism (r = 0.375 ～ 0.719, P ＜ 0.05 ).The OCD patients' SSP scores of STA had positive correlation with mature mechanism (r = 0.378, P ＜ 0.05 ).The OCD patients' STA, PsTA, I, AS, E, M,VTA and PhTA score of SSP had positive correlation with intermediate mechanism (r= 0.381 ～0.548, P＜ 0.05 ).All subscales of SSP in OCD patients, excluding SD, had positive correlation with total score of concealment (r =0.342 ～ 0.530, P ＜ 0.05 ).Conclusion OCD patients have the neurotic and aggressive features of personality;and the personalities of OCD patients have significant correlation with defense mechanism.

ObjectiveTo explore gamma resonance signals in acute medication-free schizophrenics,and the effects of antipsychotics on gamma activity.MethodsSchizophrenia patients( n=56) and normal controls ( n =18 ) underwent auditory steady-state event-related potential testing and were evaluated of their psychopathic syndromes with the positive and negative syndrome scale (PANSS) before and after 8 weeks of medication with oral chlorpromazine or clozapine.Click trains varying in rate of stimulation 40 Hz were presented; EEG-evoked power and intertrial phase synchronization were obtained in response to stimulation frequency.ResultsSchizophrenic patients showed reduced evoked power( Fz:( 5.08 ± 1.48) μV2 vs (6.91 ± 1.64) μV2 ; Cz:(4.70 ± 2.03 ) μV2 vs ( 6.93 ± 1.43 ) μV2 ; P ＜ 0.01 ) and a tendency of reduction in phase synchronization ( Fz:0.14 ± 0.04 vs 0.13 ± 0.04,P =0.051 ; Cz:0.18 ± 0.06 vs 0.17 ± 0.06,P =0.056) in response to 40 Hz stimulation.However significant correlations were not observed between oscillatory responses and clinical parameters in schizophrenic patients.There were no significant differences of gamma power and ITC in patients before and after chlorpromazine or clozapine administered.ConclusionSchizophrenia patients have deficits in the power and coherent of gamma oscillations,and can not be normalized by medication with antipsychotics.

Objective To explore the feature of functional connectivity of default mode network (DMN) and salience network (SN) in unmedicated schizophrenia patients during a resting state by functional magnetic resonance imaging (fM-RI). Methods The SPM8 and DPARSFA softwares combined with independent component analysis (ICA) were used to in-vestigate functional connectivity (FC) of the DMN and SN in 27 unmedicated patients with schizophrenia and 27 age-and gender-matched healthy controls. Results Concerning the DMN, patients with schizophrenia showed decreased FC in right inferior frontal gyrus , right precuneus(unadjusted P<0.05)and increased FC in right middle cingulate gyrus, left middle frontal gyrus(unadjusted P<0.05). With regard to the SN, patients showed reduced connectivity in left inferior frontal gyrus, right inferior frontal gyrus, left anterior cingulate, left postcentral gyrus(unadjusted P<0.05)and increased connectivity in left superior temporal gyrus(unadjusted P<0.05). Correlation analyses showed that the increased FC of left superior temporal gyrus significantly correlated with PANSS-positive symptoms(r=0.568,P=0.002)and decreased FC of right precuneus significantly negatively correlated with delusion symptom(r=-0.458,P=0.016). Conclusion This study provides evidence for resting state functional abnormalities of DMN and SN in unmedicated schizophrenia patients. These aberrant function connectivities in some brain regions of the two networks could be a source of abnormal introspectively-oriented mental actives.

Objective To investigate the relationship between the characteristics of psychological defense style and clinical symptoms of eating attitude in patients with anorexia nervosa patients. Methods Totally 92 ca?ses ( 46 cases of restricting type,46 cases of binge?eating/purging type,48 cases of early onset before 16 years old, 44 cases of late onset after 16 years old) meeting the Diagnostic and Statistical Manual of Mental Disorders,Forth Edition ( DSM?4) for anorexia nervosa (AN) were collected.92 gender?marriage?and education?matched normal cases in a psychiatric hospital were selected as the healthy control group(HC) .All were assessed with defensive style questionnaire(DSQ) and eating attitude test?26(EAT?26).DSQ and EAT?26 were compared between AN and HC,between early onset of AN( before 16 old years) and late onset of AN( after 16 old years) ,and between AN?R and AN?P.Then correlation study was done for the AN. Results Compared with HC,AN showed higher scores in the immature defense,neurotic defense ((4.49±1.13)vs (3.55±0.93),(4.33±0.76)vs (3.88±0.69), P<0.001), and higher EAT?26 median total and factor scores of dieting scale items,bulimia&food preoccupation scale items, oral control subscale items (P<0.01).Compared with AN?R,AN?P showed higher scores in the immature defense ((4.49±1.03)vs (4.79±1.13), P=0.01),and higher EAT?26 median total and factor score of bulimia&food pre?occupation scale items (P<0.05, P<0.01).The correlations between immature defense and EAT?26 total score,be?tween neurotic defense and EAT?26 total score were significant( r=0.472, P<0.001;r=0.315, P=0.002). The correlations between immature defense and EAT?26 dieting score, between neurotic defense and EAT?26 dieting score were significant( r=0.343, P<0.001, r=0.257, P=0.014).The correlations between immature defense and EAT?26 bulimia & food preoccupation score,between neurotic defense and EAT?26 bulimia & food preoccupation score were significant( r=0.523, P<0.001, r=0.267, P=0.010).The correlations between immature defense and duration were significant( r=0.375, P<0.001).The correlations between all defense factors and BMI were not sig?nificant( r=-0.15?0.25, P>0.05) . Conclusion AN patients tend to use more immature defense and neurotic de?fense compared with HC,and AN?P patients use more immature defense compared with AN?R. Immature defense and neurotic defense are related to the eating attitude,and the immature defense is related the duration.

Objective:To compare the value of Liaoning scoring system, model for end-stage liver disease (MELD), model for end-stage liver disease-Na (MELD-Na) and Blatchford score in predicting high-risk esophageal varices (EVs), hemorrhage or re-hemorrhage within 1 year and blood transfusion treatment in cirrhotic patients.Methods:Clinical data of 170 patients with esophageal varices confirmed by endoscopy from January 2018 to September 2019 were recorded. Liaoning score, MELD, MELD-Na score and Blatchford score were calculated when the first endoscopy was performed. These patients were followed up, and hemorrhage or re-hemorrhage within 1 year was recorded. Receiver operating characteristic (ROC) curve was drawn and the area under curve (AUC) was used to evaluate the accuracy of 4 scoring systems in predicting high-risk EVs, hemorrhage or re-hemorrhage within 1 year after the first endoscopy and blood transfusion. Cut-off values were obtained, and groups divided by cut-off values were compared for the proportion of high-risk EVs and hemorrhage or re-hemorrhage.Results:The cut-off value of high-risk EVs in patients with cirrhosis predicted by Liaoning score was 0.45, and the AUC was 0.702 (95% CI:0.612-0.781, P<0.01), superior to MELD, MELD-Na and Blatchford score (AUC were 0.593, 0.648, 0.610, respectively). The proportion of high-risk EVs in Liaoning score ≥0.45 and <0.45 were 71.8% (89/124) and 34.8% (16/46) with significant differences ( χ2=19.442, P<0.01). The AUC of Liaoning score for predicting hemorrhage or re-hemorrhage within 1 year was 0.680 (95% CI: 0.595-0.765, P<0.01), superior to MELD, MELD-Na and Blatchford score (AUC were 0.605,0.615,0.598, respectively). AUC of Blatchford score for predicting blood transfusion was 0.775 (95% CI:0.687-0.863, P<0.01), superior to MELD, MELD-Na and Liaoning score (AUC were 0.653, 0.719, 0.631, respectively). Conclusion:Liaoning score can predict high-risk EVs, hemorrhage or re-hemorrhage within 1 year after the first endoscopy in patients with cirrhosis and is superior to MELD, MELD-Na and Blatchford score. Blatchford score can effectively predict whether cirrhosis patients with EVs need blood transfusion.

Objective:To examine the possibility of the differentiation into islet-like cell clusters from the co-culture system of bone marrow mesenchymal stem cells (BMSCs) and islet cells.Methods:Rat BMSCs from the femur and tibia of Wistar rats were isolated and purified taken under aseptic conditions; the surface markers CD 44 and CD 90 expressions of BMSCs were detected by flow cytometry; and alizarin red staining and oil red O staining were used to identify the cells induced in the osteogenic direction and adipogenic direction, respectively. Rat islet cells from the pancreas of Wistar rats were isolated and purified; and dithiazone staining was performed for validation. The basal insulin level of the culture was detected by ELISA method. 5.6mmol/L (low glucose) and 25.0 mmol/L (high glucosa) glucose were added to the culture, respectively, and insulin release was detected by ELISA. 5-generation BMSCs and islet cells were collected and divided randomly into stem cell culture alone group (stem cell group), stem cell-islet co-culture group (co-culture group), and islet culture alone group (islet group). The morphological changes of BMSCs during co-culture were observed using an inverted phase contrast microscope; basal insulin secretion and insulin secretion stimulated by low and high glucose were tested by ELISA. Insulin protein expression in induced islet-like cell masses in co-culture group were detected by immunocytochemical staining. The ultrastructure of islet-like cells was observed by using transmission electron microscopy. Results:The positive rates of CD 44 and CD 90 were 99.48% and 99.50%, respectively; BMSCs were induced the formation of multiple calcium nodules outside the differentiation cells in the osteogenic direction, and many lipid droplets in the cytoplasm of differentiated cells in the adipogenic direction. Dithiazone staining showed that β cells in pancreatic islet were brown red and about 450 islets could be obtained per pancreas with a mean purity up to 80%. The insulin release in the low sugar group and the high sugar group were (7.105±1.551) mIU/ml and (20.231±1.592) mIU/ml, respectively, with a statistically significant difference ( P<0.05). It can be seen that local stem cells began to gather and grow upward into small clumps in the budding manner until finally forming a spherical islet-like cell cluster structure after 7 days of culture in the co-culture group. The basal insulin secretion in the stem cell group was <0.5 mIU/L. In the islet group, insulin secretion peaked on the 5th day and then gradually decreased to about 20% of the highest value on the 13th day. The insulin level of the co-culture group peaked on the 5th day, and the 13th day remained at about 40% of the peak level. There were statistically significant differences on basal insulin secretion on the 8th, 10th and 13th day between islet group and co-culture group (all P value >0.05). There was no statistically significant difference between the insulin release by islet in islet group under the stimulation of low and high sugar and that by islet-like cell cluster in co-culture group. There were a large number of brownish-yellow granules in the islet-like cell clusters after the co-culture for 14 days; and there were more secretory granules and coarse endoplasmic reticulum in the ultrastructure, showing more active protein secretion functions. Conclusions:The co-culture system of BMSCs and islet cells could induce BMSCs into differentiating into islet-like cell clusters, which can express insulin protein and had relatively mature function of insulin secretion.

Objective: To assess the relationship between body mass index (BMI) and mortality in adults of Shanxi, China. Methods: Baseline data were from the '2002 China Nutrition and Health Survey’ in Shanxi province. All the death-related investigation and follow-up visits were carried out from December 2015 to March 2016. The follow-up program covered 5 360 people from all the 7 007 participants aged 18 years and over that having complete core information, with a rate as 76.5%. Participants of this study were divided into eight groups, according to the appearance of BMI. Taking the group with the lowest mortality density as the reference group, Cox regression model was used to estimate the hazard ratio (HR) and 95% confidence interval (CI) of deaths by the whole population, gender and age groups (≥60 years, <60 years). Results were then adjusted by age, gender, smoking, alcohol use and education level from the baseline survey. Sensitivity analysis was also conducted. Results: Results from the study showed that among the total number of 67 129 person- years from the average period of 12.5 years, there were 615 deaths occurred, with the mortality density as 916 per 100 000 person-years. Taking the BMI range of 26.0-27.9 kg/m² as the reference, the aHRs of death increased to 1.90 (95%CI: 1.26-2.86), 1.68 (95%CI: 1.15-2.45), 1.49 (95%CI: 1.08-2.06) and 1.72 (95%CI: 1.07-2.76) after the multivariate adjustment, in these four groups (BMI<18.5, 18.5-19.9, 22.0-23.9 and ≥30.0 kg/m²), respectively. Low body weight (BMI<18.5 kg/m²) was associated with higher risks of death in the elderly of ≥60 years, with the aHR of death as 1.94 (95%CI: 1.20-3.15). Conclusions When BMI appeared as ≤19.9 kg/m², 22.0-23.9 kg/m² and ≥30.0 kg/m², the risks of death would increase. In addition to programs that focusing on obesity, special attention should be paid to the high risk of mortality which was caused by low-weight and malnutrition in the elderly.
