Effect of Acupuncture on Constipation in Children with Autism Spectrum Disorder / 中国康复理论与实践

Objective:To observe the effect of acupuncture on constipation in children with autism spectrum disorder (ASD). Methods:From January, 2019 to November, 2020, 50 ASD children with constipation from Rehabilitation Center of the Second Affiliated Hospital of Heilongjiang University of Chinese Medicine were admitted and randomly divided into acupuncture-rehabilitation group (n = 25) and medicine-rehabilitation group (n = 25). For constipation, the acupuncture-rehabilitation group used scalp acupuncture, body acupuncture combined with rehabilitation; the medicine-rehabilitation group took probiotics orally combined with rehabilitation. Both groups received conventional rehabilitation for constipation and the core symptoms. Constipation was treated for eight weeks, and ASD symptoms was treated for twelve weeks. After eight weeks and twelve weeks, the efficacy of constipation and the scores of main symptoms of constipation were compared, and they were also evaluated with Autism Child Behavior Scale (ABC) and Autism Treatment Evaluation Scale (ATEC). Results:Before treatment, there was no significant difference in the main symptoms of constipation, nor the scores of ABC and ATEC between two groups (P > 0.05). Eight weeks after treatment, the main symptoms of constipation significantly improved (t > 5.473, P < 0.001); twelve weeks after treatment, the efficacy of constipation and the main symptoms of constipation were better in the acupuncture-rehabilitation group than in the medicine-rehabilitation group (Z = 2.848, t = -2.139, P < 0.05). Eight weeks after treatment, the scores of ABC and ATEC significantly decreased (t > 7.139, P < 0.001), and there was no significant difference between two groups (P > 0.05); the score of behavior of ATEC significantly decreased in the acupuncture-rehabilitation group (t = 3.849, P < 0.01), and was lower than that of the medicine-rehabilitation group (t = -2.643, P < 0.05), and no significant difference in other items was found between two groups (P > 0.05); twelve weeks after treatment, the scores of ABC and ATEC were lower in the acupuncture-rehabilitation group than in the medicine-rehabilitation group (|t| > 2.156, P < 0.05). Conclusion:Acupuncture-rehabilitation can improve the longer-lasting effect of constipation, and also improve the core symptoms of ASD, which is superior to medicine-rehabilitation.

Therapeutic effect analysis of skeletal class Ⅲ malocclusion treatment by transmission straight wire technique / 华西口腔医学杂志

OBJECTIVE@#This study aimed to investigate the therapeutic effects and advantages of skeletal class Ⅲ malocclusion treatment by transmission straight wire technique.@*METHODS@#Ninety-seven patients who received treatment for skeletal class Ⅲ malocclusion at the Department of Stomatology, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 2012 to January 2017 were selected for this retrospective study. All these patients refused surgery. They were divided into two groups in accordance with the type of skeletal malocclusion: mild-to-moderate skeletal malocclusion group (-4°≤ANB <0°) and severe skeletal malocclusion group (-8°≤ANB<-4°). Each of the two groups was divided further into two small groups in accordance with the technique used: T group (transmission straight wire technique) and M group (MBT technique).@*RESULTS@#The crossbite of all 59 patients in the mild-to-moderate skeletal malocclusion group was successfully treated. The molars were classified as classⅠrelationship, and the facial profile improved. Significant differences were found in the values of U1/SN angle, L1/MP angle, and Lip-Diff between the T and M groups before and after the treatment (P<0.05). The extent of incisor root resorption was lighter in the T group than in the M group (P<0.05). In the severe skeletal malocclusion group, the crossbite of all 38 patients was cured or partially cured. Fourteen patients showed severe lower anterior teeth inclination (five in the T group and nine in the M group), and the profiles did not significantly improve. Significant differences were observed in the values of U1-NA value, U1/SN angle, L1-NB value, L1/MP angle, LLP, and Lip-Diff between the T and M groups before and after the treatment (P<0.05). The extent of incisor root resorption was lighter in the T group than in the M group (P<0.05).@*CONCLUSIONS@#Relative to the MBT technique, the transmission straight wire technique has great advantages in improving facial profile, reducing the compensatory inclination of the upper and lower anterior teeth, and reducing the risk of root resorption in the treatment of skeletal class Ⅲ malocclusion.

Close association between abnormal expressed enzymes of energy metabolism and diarrhea-predominant irritable bowel syndrome / 中华医学杂志(英文版)

BACKGROUND@#Irritable bowel syndrome (IBS) is one of the most common functional intestinal diseases, but its pathogenesis is still unknown. The present study aimed to screen the differentially expressed proteins in the mucosa of colon between IBS with diarrhea (IBS-D) patients and the healthy controls.@*METHODS@#Forty-two IBS-D patients meeting the Rome III diagnostic criteria and 40 control subjects from July 2007 to June 2009 in Chinese PLA General Hospital were enrolled in the present study. We examined the protein expression profiles in mucosa of colon corresponding to IBS-D patients (n = 5) and controls (n = 5) using 2-dimensional gel electrophoresis (2-DE) and mass spectrometry (MS). Secondly, Western blot and immunohistochemical analysis were carried out to validate the screened proteins in 27 IBS-D patients and 27 controls. Thirdly, high-performance liquid chromatography (HPLC) was further carried out to determine ATP concentration in the mucosa of colon between 10 IBS-D patients and 8 controls. Comparisons between 2 groups were performed by Student's t-test or Mann-Whitney U-test.@*RESULTS@#Twelve differentially expressed proteins were screened out. The α-enolase (ENOA) in the sigmoid colon (0.917 ± 0.007 vs. 1.310 ± 0.100, t = 2.643, P = 0.017) and caecum (0.765 ± 0.060 vs. 1.212 ± 0.122, t = 2.225, P = 0.023), Isobutyryl-CoA dehydrogenase (ACAD8) in the sigmoid colon (1.127 ± 0.201 vs. 1.497 ± 0.392, t = 7.093, P = 0.008) of the IBS-D group were significantly lower while acetyl-CoA acetyltransferase (CT) in the caecum (2.453 ± 0.422 vs. 0.931 ± 0.652, t = 8.363, P = 0.015) and ATP synthase subunit d (ATP5H) in the sigmoid (0.843 ± 0.042 vs. 0.631 ± 0.042, t = 8.613,P = 0.007) of the IBS-D group was significantly higher, compared with the controls. The ATP concentration in the mucosa of the sigmoid colon in IBS-D group was significantly lower than that of control group (0.470 [0.180, 1.360] vs. 5.350 [2.230, 7.900], U = 55, P < 0.001).@*CONCLUSIONS@#Many proteins related to energy metabolism presented differential expression patterns in the mucosa of colon of the IBS-D patients. The abnormalities in energy metabolism may be involved in the pathogenesis of IBS which deserves more studies to elucidate.

Advance in Relationship between Autism Spectrum Disorders and Microbiome (review) / 中国康复理论与实践

It has been increasingly recognized that the presence of a healthy and diverse gut microbiota is important to the development of central nervous system and emotional processing for children with autism spectrum disorders (ASD). The interconnection of gut microbiome and brain function has significantly contributed to establishing the microbiota-gut-brain axis as an extension of the well-accepted gut-brain axis concept. The bidirectional interaction between the gut microbiota and the brain occurs through various pathways including serotonin, hypothalamus-pituitary-adrenal axis, neurotrophin, and the immune system. The microbiota-gut-brain axis has been shown to influence the behaviors associated with neuropsychiatric conditions. Modulation of this gut microbiota as a novel therapy for ASD is gaining interest. This paper summarized the status of neuropsychological microbiome, which provided evidence supporting the role of gut microbiota in modulating neuropsychological functions of the central nervous system and exploring the potential underlying mechanisms.

Up-regulation of GABAAα1in ventrolateral periaqueductal gray in rats is associated with formalin-induced acute pain / 基础医学与临床

Objective To investigate the expression of γ-aminobutyric acid A receptor α1 subunit (GABAAα1) in the ventrolateral periaqueductal gray (vLPAG) in rats with formalin-induced acute pain. Methods The rats were randomly divided into two groups:control group(group C) and formalin-induced pain group(group F),12 rats in each group:0.9% sodium chloride solution or 2% formaldehyde 50 μL was injected into the ventral surface of right hind paw respectively. The pain scores were recorded for every 5 minutes and the mechanical pain threshold were recorded for every 10 minutes until 1 h. The expression levels of GABAAα1in vLPAG were determined by Western blot analysis in each group.Results The rats in formalin group showed significant nociceptive behaviors immedi-ately, such as paw withdrawal and/or paw licking. Results demonstrated that the rats exhibited a biphasic response to pain. The pain behavior scores in group F were significantly higher than that in group C (P<0.05),and the mechanical pain threshold in group F was decreased after injection compared with group C(P<0.05). The expression of GABAAα1 protein in group F was significantly higher than that in group C (P<0.05).Conclusions The up-regulation of GABAAα1 expression in ventrolateral periaqueductal gray is associated with the decrease of pain threshold in rats with acute pain.

Inhibin B level helps evaluate the testicular function of prepubertal patients with varicocele / 中华男科学杂志

Effects of hyperoside on the myocardical activities of ATPases and expressions of Cx43 and Kir2.1 in arrhythmia rats induced by ischemia-reperfusion / 中成药

AIM To investigate the effects of hyperoside,an anti-arrhythmic agent capable of reducing myocardial infarct size,on arrhythmic rats induced by ischemia-reperfusion (I/R) and the corresponding mechanism.METHODS Male SD rats were randomly assigned to sham operation group,model group and hyperoside group (50 mg/kg,n =15).The I/R model was reconstructed by the ligation of left anterior descending coronary artery for 30 min ischemia.Rats in the hyperoside group were injected with 50 mg/kg hyperoside intraperitoneally 10 min before ischemia.Heart rate,mean arterial pressure (MAP) and heart rate systolic blood pressure product (RPP) at time points of 10 min before ischemia (T0),30 min after ischemia (T1),30 min (T2),60 min (T3),120 min (T4) after reperfusion were recorded.ELISA method was used to determine serum CK-MB and cTnI,spectrophotometry to measure Na+-K+-ATPase and Ca2+-Mg2+-ATPase levels,HE staining to observe myocardial tissue changes,immunohistochemistry to investigate Cx43 protein,and Western blot to detect Kir2.1 protein expression.RESULTS At T1,T2,T3 and T4,the model group demonstrated significantly lower HR,MAP and RPP than those in the sham operation group (P ＜ 0.05),whereas the hyperoside group had higher HR,MAP and RPP than the model group.Both hyperoside group and the model group shared significantly higher arrhythmia score,levels of CK-MB and cTnI than the sham operation group (P ＜ 0.05) while their lower activities of Na +-K +-ATPase and Ca2+-Mg2+-ATPase,protein expressions of Cx43 and Kir2.1 than the sham operation group were noticed as well.But the hyperoside group displayed its lower arrhythmia score,levels of CK-MB and cTnI,and yet higher activities of Na +-K +-ATPase and Ca2 +-Mg2 +-ATPase,protein expressions of Cx43 and Kir2.1 than the model group (P ＜0.05).CONCLUSION Hyperoside in improving ventricular arrhythmia of I/R rats may contribute to the activity restoration of Na +-K +-ATPase and Ca2 +-Mg2 +-ATPase,and the up-regulation of Cx43 and Kir2.1 protein expressions.

Association of in-stent restenosis with serum Gal-3 and MMP-9 levels / 西安交通大学学报(医学版)

Objective To investigate the relationship of galectin-3 (Gal-3)and matrix metalloproteinase-9 (MMP-9)with in-stent restenosis (ISR).Methods We consecutively recruited 434 patients who had undergone successful drug eluting stent (DES)implantation.Then we divided them into ISR group (n=41)and NO-ISR group (n=393)according to the results of coronary angiography review.Independent risk factors for ISR were found out by multivariate analysis and the two groups were matched for these factors except for Gal-3 and MMP-9 .After elim-ination of the influence of confounders,serum Gal-3 and MMP-9 were compared between the groups and their rela-tions with the severity of ISR were analyzed.Patients were grouped based on Gal-3 and MMP-9 concentrations and major adverse cardiac events (MACEs)were compared between the two groups.Results After elimination of the influence of confounders,the results showed that serum levels of Gal-3 and MMP-9 were significantly higher in ISR group than in NO-ISR group (P＜0.001).Serum levels of Gal-3 and MMP-9 increased with the increased grade of classification.Serum levels of Gal-3 and MMP-9 were obviously higher in classes Ⅲ and Ⅳ ISR than in class Ⅰ (P＜0.05).Patients with higher levels of Gal-3 and MMP-9 had a higher incidence of MACEs (P＜0.01).ISR group had a higher incidence of MACEs than NO-ISR group (P＜0.05).Conclusion Serum levels of Gal-3 and MMP-9 are correlated with ISR and its severity,and they are independent risk factors for ISR.The rate of MACEs during follow-up period was increased with the increased levels of Gal-3 and MMP-9 .

Therapy approaches in treatment of recurrent ischemic angina with internal mammary artery bridge after coronary artery bypass grafting / 西安交通大学学报(医学版)

Objective To investigate the clinical therapeutic methods and their curative effects in recurrent ischemic angina for internal mammary artery resterosis after coronary artery bypass grafting (CABG).Methods We enrolled the patients who had recurrence of ischemic angina for restenosis of internal mammary artery graft after CABG as research subjects in the Affiliated Hospital of Yan'an University from January 2014 to January 2016.The 42 patients were divided into three groups according to the different treatment approaches for recurrence of ischemic angina:Group A (n=22)who received internal mammary artery interventional therapy;Group B (n=12)who received coronary artery bypass grafting treatment;and Group C (n=8)who received left subclavian artery proximal stent treatment.Then we compared the clinical therapeutic effects in the three groups.Results The success rate in Group C was 100%,which was the highest in the three groups,and the post-operative restenosis rate was 0.The hospitalization time was significantly shorter in Group A than in Group B (P＜0.05).However,the two groups did not significantly differ in mortality,success rate or restenosis rate (P＞0.05).Conclusion We should select the appropriate treatment according to the patient's specific situation for recurrent ischemic angina. Endovascular treatment has evident therapeutic effects,rapid postoperative recovery,and lower treatment risk, making it the preferred treatment when possible.

Correlation between the degree of coronary artery stenosis and endothelial dysfunction in patients with coronary heart disease and subclinical hypothyroidism / 西安交通大学学报(医学版)

Objective To study the correlation between coronary artery stenosis and endothelial dysfunction in patients with coronary heart disease and subclinical hypothyroidism.Methods According to the results of coronary angiography and thyroid function,the patients were divided into coronary heart disease with subclinical hypothyroidism (group A,n=71),coronary heart disease without subclinical hypothyroidism (group B,n=73), and normal coronary angiography (control group,n=59).The degree of coronary artery stenosis was evaluated by Gensini integral method.Fasting blood was taken to measure nitric oxide (NO),high sensitivity C reactive protein (hs-CRP),and endothelin (ET)to evaluate endothelial dysfunction.Results TC,TG,LDL-c,FT3,TSH,hs-CRP,ET and Gensini score were higher in Group A than in Group B and control group (P＜0.05).The level of NO in Group A and Group B were lower than that in control group (P＜0 .0 5).Multivariate Logistic regression analysis showed that age,TSH,ET and NO were independent risk factors for coronary heart disease.ET and NO levels in patients with coronary heart disease combined with subclinical hypothyroidism were correlated with Gensini scores (r=0.431,r=-0.383,P＜0.001).Conclusion Subclinical hypothyroidism may cause endothelial dysfunction in patients with coronary heart disease,which may increase cardiovascular risk in these patients.

Predictive values of the platelet to lymphocyte ratio and neutrophil to lymphocyte ratio for drug eluting stent restenosis / 西安交通大学学报(医学版)

Objective To investigate the predictive values of platelet to lymphocyte ratio (PLR) and neutrophil to lymphocyte ratio (NLR)before percutaneous coronary intervention (PCI)and a reexamination of coronary angiography (CAG)on the development of in-stent restenosis (ISR)in patients implanted with coronary drug eluting stent (DES).Methods For this study we enrolled 123 patients who had undergone successful drug eluting stent implantation (SI)and a further CAG reexamination.Another 45 patients with non-coronary heart disease (NC)served as controls.PLR and NLR were measured before DES implantation or CAG and compared between the groups.Patients in SI group were further divided into two subgroups based on the results of CAG reexamination:ISR group and no-ISR group.Hematologic data were reexamined before further CAG and compared between the subgroups.Receiver operator characteristic curve (ROC)was drawn to evaluate the predictive values of PLR and NLR for ISR.Results PLR and NLR before PCI or a further CAG were significantly higher in ISR group (34 patients)than in non-ISR group (89 patients,P＜0.05).Before PCI,the best cutoff value of PLR in screening restenosis was 107.20;the sensitivity and the specificity were 64.7% and 65.2%.The best cutoff value of NLR in screening restenosis was 2.72; the sensitivity and the specificity were 61.8% and 70.8%. Before CAG reexamination,the best cutoff value of PLR in screening restenosis was 160.08;the sensitivity and the specificity were 26.5% and 97.8%.The best cutoff value of NLR in screening restenosis was 2.08;the sensitivity and the specificity were 73.5% and 56.2%.Conclusion Both PLR and NLR before PCI or CAG reexamination can be predictors of ISR in patients implanted with DES.

Association of AIP and serum bilirubin with coronary in-stent restenosis / 西安交通大学学报(医学版)

Objective To analyze the association of atherogenic index of plasma (AIP)and serum bilirubin with coronary in-stent restenosis after drug-eluting stent implantation.Methods For this research we recruited 268 patients who had undergone successful drug-eluting coronary stent implantation and then received coronary angiography.Both ends (from the edge of the supporting frame≤5 mm)or the vessel's diameter stenosis ≥50% were used as the definition of restenosis.According to the results of coronary angiography,the subjects were divided into restenosis group (42 cases)and non-restenosis group (226 cases).The total bilirubin,direct bilirubin,indirect bilirubin and AIP in the two groups were compared to explore the correlation of AIP and serum bilirubin with in-stent restenosis.Results AIP in restenosis group was significantly higher than that in non-restenosis group (P＜0.05).The level of total bilirubin was significantly lower in the former group than in the latter one (P＜0.05). Conclusion AIP is a risk factor for restenosis,and serum total bilirubin is a protective factor for coronary stent restenosis.

Effect of simulated transportation vibration on suspended erythrocyte quality / 军事医学

Objective To investigate the effect of vibration on the quality of suspended erythrocytes during transportation, and explore suitable experimental vibration conditions.Methods Three intensities(highway truck vibration, random vibration of fixed goods in a caterpillar, and combined wheeled vehicle vibration)were selected to simulate suspended erythrocyte transportation using electromagnetic vibration test system.Suspended erythrocytes of the same storage were randomly divided into three groups:highway truck vibration(group1),random vibration of fixed goods in a caterpillar(group 2),and combined wheeled vehicle vibration(group 3).The suspended erythrocytes were stored for 11 days and 26 days.The control group was stored with conventional methods.Suspended erythrocytes were vibrated for 1 hour,samples were collected before and after vibration,while free hemoglobin(FHb),K+,and LDH were tested.Results The changes in FHb and LDH after vibration were gradually increased with the magnitude of vibration(P<0.05).There was no significant difference in K +between the three vibration levels.The increase in FHb in suspended erythrocytes stored for 26 days was higher than 11days after random vibration of fixed goods in a caterpillar and combined wheeled vehicle vibration(P<0.05).There was no significant difference in the change in FHb between day(d)26 and d 11 after highway truck vibration.Under the same magnitude of vibration,the change in LDH in the d 26 suspended erythrocytes was more significant than that of the d 11, and no significant difference was found in the change in K +between d 26 and d 11. Conclusion The damage to suspended erythrocytes after combined wheeled vehicle vibration is more obvious than that by the other two vibrations.The vibration environment of combined wheel vehicles is more suitable for simulating the vibration damage to suspended erythrocyte vibration.Suspended erythrocytes with a longer storage time have significant changes in FHb and LDH after transportation vibration, and the length of storage time of suspended red blood cells might affect the vibration injury.
