RESUMO
The intestinal flora and gut barrier function are of great significance for gut function and human health. When the intestinal flora is disrupted and the gut barrier structure is disrupted, it can lead to bacterial translocation, endotoxin influx into the bloodstream, and the production of pro-inflammatory factors, leading to various tissue damage in the body. Tongfu method in TCM can affect the intestinal environment by regulating intestinal permeability and immune response, restoring normal intestinal movement, and regulating the structure and metabolites of intestinal flora, thereby maintaining intestinal homeostasis and body health. The research on regulating intestinal flora and improving intestinal barrier function by Tongfu method can provide reference for further research on the relationship between TCM and intestinal microecology, and provide ideas for clinical treatment.
RESUMO
【Objective】 To examine the association between psychological behavioral problems and sleep problems in disabled children in Beijing, in order to provide reference for reducing the sleep problems of disabled children. 【Methods】 From September 2017 to February 2018, children with disabilities aged 6 to 17 years were selected by random sampling, and were investigated by a self-designed questionnaire to get their demographic characteristics.Pediatric Symptom Checklist-17 (PSC-17) was used to assess psychological and behavioral problems.The relationship between psychological behavior and sleep problems was analyzed by binary Logistic regression. 【Result】 Totally 650 children with disabilities were included in the study.The detection rates of sleep problems was significantly different in children with different genders, different school styles, different types of disabilities and different grades of disabilities (χ2=3.984, 4.437, 12.925, 18.104, P<0.001). There was statistically significant difference in the detection rate of sleep problems between children with and without psychological and behavioral problems (χ2=30.722, P<0.001).Psychological and behavioral problems were the main risk factors for sleep problems of disabled children (OR=2.540, 95%CI:1.740 - 3.709).The risk of sleep problems in day students with disabilities was 1.577 times as high as that of boarders with disabilities. 【Conclusions】 Psychological and behavioral problems of disabled children are related to sleep problems.Improving psychological and behavioral status can effectively prevent their sleep problems.
RESUMO
Objective:To study the regulatory effect of Wumen-Yiji powder on 5-hydroxytryptamine (5-HT) signal transduction system in intestine and hypothalamus of diarrhea irritable bowel syndrome (IBS-D) model rats. Methods:Sixty male SD rats were randomly divided into blank group (10 rats) and diarrhea irritable bowel syndrome group (50 rats). The diarrhea irritable bowel syndrome group formed the diarrhea irritable bowel syndrome model after 2 weeks of senna leaf gavage and restraint stress. They were randomly divided into model group, deshute group (1.5 mg/kg), low, medium and high dose group of Wumen-Yiji San (6, 12, 24 g/kg), with 10 rats in each group. After continuous administration for 2 weeks, the contents of 5-HT in serum, colon and hypothalamus were detected by ELISA; HE staining was used to observe the pathological changes of colon in each group. The protein and mRNA levels of tryptophan hydroxylase 1 (TPH-1), serotonin receptor 3 (5-HT3R), serotonin receptor 4 (5-HT4R), serotonin transporter (SERT) in colon and hypothalamus were detected by Western blot and RT-PCR, respectively. Results:Compared with the model group, the pathological morphology of colon in each treatment group was improved. Compared with the model group, the level of 5-HT in serum and colon significantly decreased ( P<0.05), and the level of 5-HT in hypothalamus of rats in the low, medium, high dose group of Wumen-Yiji San significantly increased ( P<0.05). The expression of TPH-1, 5-HT3R and 5-HT4R protein significantly decreased ( P<0.05), and the expression of SERT protein in the medium, high dose group of Wumen-Yiji San significantly increased ( P<0.05). The expression of TPH-1, 5-HT3R and 5-HT4R protein in hypothalamus increased ( P<0.05), and the expression of SERT protein in the high dose group of Wumen-Yiji San significantly decreased ( P<0.05). The mRNA levels of TPH-1 (4.778 ± 0.604, 3.278 ± 0.668, 1.670 ± 0.361 vs. 6.877 ± 0.148), 5-HT3R (3.807 ± 0.463, 2.697 ± 0.455, 1.132 ± 0.136 vs. 6.322 ± 0.778), 5-HT4R (4.521 ± 0.234, 2.801 ± 0.351, 1.331 ± 0.142 vs. 6.741 ± 0.293) in colon tissue of low, medium and high dose groups of Wumen-Yiji San decreased ( P<0.05). The level of 5-HT4R mRNA (0.616 ± 0.208, 0.726 ± 0.226 vs. 0.521 ± 0.062) increased ( P<0.05), and the level of SERT mRNA (1.563 ± 1.023 vs. 2.612 ± 1.035) in medium, high dose group of Wumen-Yiji San decreased ( P<0.05). Conclusion:The result showed that Wumen-Yiji San could regulate the expression of 5-HT signaling system relating proteins and mRNA in the colon and hypothalamus of IBS-D rats within a certain dose range, so as to improve the symptoms of IBS-D.
RESUMO
From September 2017 to February 2018, 650 disabled children and adolescents aged 6-to 17-year-old in Beijing were matched 1∶1 to those in normal physical condition with same age, gender and place of residence. All children and adolescents were investigated for self-injury status in the last year to understand the difference of self-injury incidence between groups. Multivariate unconditional logistic regression model was applied for exploring relevant factors of self-injury of children and adolescents. This study found that the disability, insufficient sleep, difficulty falling asleep, and sleeping late were associated with self-injury of children and adolescents.
RESUMO
Objective To explore the relationship between collateral circulation and clinical manifestation after se-vere stenosis or occlusion of internal carotid artery. Methods According to the clinical manifestation, 78 cases of ICA ste-nosis or occlusion confirmed by digital subtraction angiography (DSA) were divided into two groups:asymptomatic group (n=31) and symptomatic group (n=47). Collateral circulation pathway in circle of Willis and the mean flow velocity of the middle cerebral arteries (MVMCA) were measured by Transcranial Doppler Ultrasonography (TCD). The correlation of the types of intracranial collateral circulation and clinical manifestation was analyzed. Results ① The collateral circulation opening rate of severe stenosis or occlusion of internal carotid artery in 78 cases of patients was 70.5%(55/78). The collat-eral patency rate (27/31, 87.1% of patients) was higher in asymptomatic group than in the symptomatic group (28/47, 59.6%of patients)(P<0.01).②Collateral patency of anterior communicating artery (ACoA)in asymptomatic group (24/31, 77.4%of patients) was higher than that in symptomatic group (20/47, 42.6%of patients) (P<0.01). Collateral patency of ophthalmic artery (OA) in symptomatic group (21/47, 44.7%of patients) was higher than that in asymptomatic group(6/31, 19.4%of patients)(P<0.05). The opening rate of ACoA was significantly higher than that of either the posterior commu-nicating artery (PCoA) or OA collateral circulation in asymptomatic group (P<0.05).③The mean flow velocity of the af- fected side middle cerebral arteries (MVMCA) in asymptomatic group (51.58±12.36cm/s) was significantly higher than that in symptomatic group (32.23±10.31cm/s) (P<0.01). Conclusion The clinical manifestation is closely related to arterial circle of Willis collateral circulation opening after severe stenosis or occlusion of internal carotid artery and collateral patency of anterior communicating artery is the major collateral supply vessel.

Objective To investigate the pathogenesis of cerebral watershed infarction (CWI) through analyzing the appearance examined by Color duplex Imaging(CDI) and transcranial doppler (TCD).Methods One hundred and forty-two patients with CWI diagnosed by magnetic resonance imaging(MRI) were enrolled in the study group and 150 patients with acute cerebral infarction were enrolled in the control group.The results of CDI and TCD were retrospectively analyzed of the two groups.The vascular stenosis,plaque detection rate,plaque characteration,plaque scores,the cause of low blood volume,intracranial collateral circulation were compared between the two groups to investigate the pathogenesis of CWI.Results Among the 142 cases in the study group,there were 72 cases of severe stenosis and occlusion,21 cases of moderate stenosis,31 cases of mild stenosis and 18 cases without stenosis and there were 19 cases of severe stenosis and occlusion,41 cases of moderate stenosis,23 cases of mild stenosis and 67 cases without stenosis among the 150 cases in the control group.There were significant differences in the two groups (x2 =66.583,P =0.000).There were significant differences on the plaque detection rate between the two groups (80.99% (115/142) vs 49.33% (74/150),x2 =32.010,P =0.000).There were significant differences on the scores of plaque between the study group and the control group ((11.47 ± 3.78) points vs (6.57 ± 3.53) points,t =4.019,P =0.001).There were significant differences on the defined cause of low blood volume between the study group and the control group (54.93% (78/142) vs 11.33% (17/150),x2 =63.164,P =0.000).There were 50 patients had collateral circulation in the study group and 38 cases in the control group,there were no significant differences between the two groups (35.31% (50/142) vs 25.33% (38/150),x2 =3.381,P =0.066).Conclusion Angiostegnosis,microemboli from the unstable atherosclerosis plaque,lower perfusion on the basis of hypovolemia are all the pathogenesis of CWI.CDI combine with TCD can provide more information in vascular evaluation and treatment.
RESUMO
This study explored a novel systemic community-based model for detecting and managing people living with HIV/AIDS (PLWHA). Both quantitative and qualitative research methods were used in this study. A quantitative questionnaire investigation was conducted in a sample of 1192 subjects which were randomly selected from two areas with high HIV prevalence, Xiangfan City and Shiyan City of Hubei Province, China. Twenty-two medical and health service staffs were interviewed by semi-structured questionnaire focusing on awareness, status, problems, and suggestions about community-based Voluntary Counseling and Testing and Provider Initiated Testing and Counseling (VCT/PITC). And they were organized to discuss about the aforementioned issues in Xiangfan City and Shiyan City, respectively. Our results showed that the accessibility and availability of the general VCT/PITC were bad. About 28.3% had known and only 4.9% had made use of VCT/PITC. Developing community-based VCT/PITC had some special advantages that can overcome some existing problems to remedy the aforementioned defects. We are led to conclude that, to maximize the availability and uptake rate of the VCT/PITC, we plan to detect PLWHA by developing the community-based VCT/PITC through 4 paths. Then we establish the community HIV health care center constituted of 8 sectors to provide an overall management. Thus, we can effectively detect and manage the PLWHA with a new systemic community-based model.

RESUMO
Objective To illustrate the evaluation effect of bivariate analysis of sensitivity and specificity meta-analysis model in diagnosis test to provide basis for selecting better evaluation method of diagnostic test.Methods Bivariate model was presented by reanalyzing the data from a published meta-analysis of two diagnostic techniques in diagnosis of schistosomiasis japonica.Results The bivariate model could directly provide summary estimates of(logit)sensitivity,specificity and DOR with corresponding 95% CI for two diagnostic tests(IHA and ELISA).Also,it could elicit any significant difference that existed among sensitivity,specificity and DOR between the two diagnostic methods,and incorporate any correlation that existed between sensitivity;specificity.Conclusion The bivariate model preserves the two dimensional nature of the original data,and separates effects of sensitivity and specificity,which is more rational than a net effect on diagnostic odds ratio scale as in SROC approach.The bivariate model is appropriate and agile,and can be used as an extension and improvement of the traditional SROC method.
