ABSTRACT
OBJECTIVES@#To explore the association between maternal gestational diabetes mellitus (GDM) exposure and the development of autism spectrum disorder (ASD) in offspring.@*METHODS@#A case-control study was conducted, recruiting 221 children with ASD and 400 healthy children as controls. Questionnaires and interviews were used to collect information on general characteristics of the children, socio-economic characteristics of the family, maternal pregnancy history, and maternal disease exposure during pregnancy. Multivariate logistic regression analysis was used to investigate the association between maternal GDM exposure and the development of ASD in offspring. The potential interaction between offspring gender and maternal GDM exposure on the development of ASD in offspring was explored.@*RESULTS@#The proportion of maternal GDM was significantly higher in the ASD group compared to the control group (16.3% vs 9.4%, P=0.014). After adjusting for variables such as gender, gestational age, mode of delivery, parity, and maternal education level, maternal GDM exposure was a risk factor for ASD in offspring (OR=2.18, 95%CI: 1.04-4.54, P=0.038). On the basis of adjusting the above variables, after further adjusting the variables including prenatal intake of multivitamins, folic acid intake in the first three months of pregnancy, and assisted reproduction the result trend did not change, but no statistical significance was observed (OR=1.94, 95%CI: 0.74-5.11, P=0.183). There was an interaction between maternal GDM exposure and offspring gender on the development of ASD in offspring (P<0.001). Gender stratified analysis showed that only in male offspring of mothers with GDM, the risk of ASD was significantly increased (OR=3.67, 95%CI: 1.16-11.65, P=0.027).@*CONCLUSIONS@#Maternal GDM exposure might increase the risk of ASD in offspring. There is an interaction between GDM exposure and offspring gender in the development of ASD in offspring.

Objective: To observe the effects of moxibustion on colonic inflammation, and the expressions of ubiquitin and nucleotide-binding oligomerization domain (Nod)-like receptor protein 3 (NLRP3) proteins in rats with ulcerative colitis (UC), and to explore the anti-inflammatory mechanism of moxibustion in the UC treatment. Methods: Clean grade male Sprague-Dawley (SD) rats were randomly divided into a normal group (NG), a model group (MG), a moxa-stick moxibustion group (MSMG) and a Western medicine group (WMG). UC model was prepared by freely drinking 35 g/L dextran sulfate sodium (DSS) solution. Bilateral Tianshu (ST 25) were selected for mild moxibustion treatment in the MSMG; mesalazine solution was intragastrically administrated in the WMG. Rats in the NG and MG were only grasped and fixed as in the MSMG without any treatment. After treatment, hematoxylin-eosin (HE) staining was performed to observe and score the colonic pathological damage under light microscope; immunofluorescence method was used to determine the expression of colonic ubiquitin protein; immunohistochemical method was used to detect the expressions of colonic interleukin (IL)-1β and NLRP3 proteins. Results: The colon tissue was severely injured, and the pathological score was significantly increased in the MG than in the NG (P<0.01), and the protein expressions of ubiquitin, NLRP3 and IL-1β in the colon were significantly increased (all P<0.01). Compared with the MG, the colonic damage was repaired, the inflammation and pathological scores were reduced, and the ubiquitin, NLRP3 and IL-1β protein expressions were decreased in the MSMG and WMG (all P<0.01). Correlation analysis revealed that the ubiquitin protein expression was correlated with the colonic pathological score and the NLRP3 protein expression (r=0.677, P<0.01; r=0.536, P<0.05). Conclusion: Moxibustion can down-regulate the protein expressions of ubiquitin, NLRP3 and IL-1β in the colon of UC rats, which may be one of the mechanisms to promote the repair of colonic inflammatory lesions and exert anti-inflammatory effects.
ABSTRACT
Objective: To summarize the clinical application patterns in acupuncture-moxibustion treatment of AD by reviewing the clinical literatures on acupuncture-moxibustion for Alzheimer disease (AD) published between January 2009 and December 2019. Methods: China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), Chinese Medicine Acupuncture-moxibustion Information Database, PubMed Medical Data Retrieval Service System, Springer Database and Ovid Technologies (OVID) were retrieved to screen clinical studies of acupuncture-moxibustion treatment of AD according to the inclusion and exclusion criteria to conduct quantitative, clustering and association analyses. Results: In acupuncture-moxibustion treatment of AD, the frequently used points were Baihui (GV 20), Zusanli (ST 36), Sishencong (EX-HN 1), Taixi (KI 3), Sanyinjiao (SP 6), and Neiguan (PC 6) in the descending order. Regarding meridians, the most frequently used one was the Governor Vessel, followed by the Stomach Meridian of Foot Yangming and Gallbladder Meridian of Foot Shaoyang. From the perspective of body regions, the points in the head-face region and the lower-limb region had the highest frequencies, followed by the upper-limb, back and chest-abdomen regions. The point group, Baihui (GV 20) and Sishencong (EX-HN 1)-Neiguan (PC 6)-Sanyinjiao (SP 6), showed the most significant association, and the group winning the second place was Baihui (GV 20) and Sishencong (EX-HN 1)-Neiguan (PC 6)- Zusanli (ST 36). The clustering analysis showed that the commonly used point pairs included Zusanli (ST 36)-Sishencong (EX-HN 1) and Taixi (KI 3)-Sanyinjiao (SP 6), which were closely associated with Baihui (GV 20). By analyzing the three commonly used acupuncture-moxibustion methods, acupuncture plus medication was found achieving the best result in the total effective rate and mini-mental state examination (MMSE) score, followed by monotherapy of electroacupuncture therapy, and these two methods were superior to acupuncture alone (P<0.05); the scores of MMSE, Alzheimer disease assessment scale-cognitive section (ADAS-cog) and activity of daily living scale (ADL) showed significant improvements after treatment (all P<0.01). Conclusion: In the acupuncture-moxibustion prescriptions for AD, the main points are Baihui (GV 20), Sishencong (EX-HN 1), Neiguan (PC 6), Zusanli (ST 36), Sanyinjiao (SP 6) and Taixi (KI 3). Monotherapy of acupuncture has the highest frequency amongst the treatment methods, but its effective rate is lower than that of acupuncture plus medication and monotherapy of electroacupuncture.
ABSTRACT
Objective To explore the action mechanism of moxibustion in treating Crohn's disease (CD) by observing the effect of herbal cake-partitioned moxibustion on the expression of NLRP3 inflammasome (NLRP3, ASC and Caspase-1) and IL-1β. Method Male Sprague Dawley (SD) rats of clean conventional grade were randomized into a normal control group (NG), a model control group (MG), a herbal cake-partitioned moxibustion control group (MoxG), and a sham moxibustion control group (SMG). The CD rat models were developed by using the mixture of 2, 4, 6-trinitrobenzene sulfonic acid (TNBS) and alcohol via enema. When the models were successfully developed, the MoxG received moxibustion intervention at bilateral Tianshu (ST25) and Qihai (CV6), and the SMG were administered by unlighted moxa cones. At the end of treatment, the length of each rats' colon and the colon macroscopic damage index (CMDI) score were recorded, the histopathological variations of rats' colons were observed by adopting HE staining and light microscope, and the expressions of NLRP3, ASC, Caspase-1 and IL-1β in rats' colons were determined by using immunohistochemical technique. Result Compared to the NG, the MG had its rats' colons present with severe damages, fissured ulcers and inflammatory cell infiltration with edema, and granulomas in submucosa of some colons, and its expressions of NLRP3, ASC, Caspase-1 and IL-1β increased significantly (P<0.05);compared to the MG, the MoxG had rats' colons present with improved structures and reduced intestinal inflammation, and its expressions of NLRP3, ASC, Caspase-1 and IL-1β dropped significantly (P<0.05); the SMG had its rats' colon inflammation present similarly to the MG, and its expressions of NLRP3, ASC, Caspase-1 and IL-1β had no significant difference (P>0.05). Conclusion Herbal Cake-partitioned moxibustion can down-regulate the expressions of NLRP3, ASC, caspase-1 and IL-1β in CD rats' colons to promote the repair of colon damage.
ABSTRACT
Objective:To observe the effect of moxibustion on the protein and mRNA expressions of corticotropin-releasing factor (CRF)and corticotropin-releasing factor receptor 1 (CRFR1) in hypothalamus of trinitrobenzene sulfonic acid (TNBS)-induced experimental colitis rats,and to explore the central mechanisms of moxibustion in improving visceral pain and the pain-related emotions in experimental colitis rats.Methods:Thirty-six Sprague-Dawley (SD) rats were randomly divided into a normal group (NG),a model group (MG),a herb-partitioned moxibustion group (HPMG) and a sham herb-partitioned moxibustion group (SHPMG).Except the NG,rats in the remaining three groups all received TNBS enema to establish experimental colitis models.The HPMG received herb-partitioned moxibustion (HPM) at bilateral Tianshu (ST 25) and Qihai (CV 6) for intervention;for the SHPMG,the herbal cakes and moxa cones were only placed on the acupoints but not ignited;rats in the MG and NG were only fixed in the same way as those in the HPMG but did not receive any treatment.At the end of the intervention,the abdominal withdrawal reflex (AWR) score,the open field test (OFT) score and the elevated plus maze (EPM) score were observed to measure the changes in visceral pain and pain-related emotions of the rats.The enzyme-linked immunosorbent assay (ELISA) was used to examine the expressions of CRF and CRFR1 proteins in hypothalamus;the fluorescence-based quantitative polymerase chain reaction (PCR) was used to detect the expressions of CRF and CRFR1 mRNAs in hypothalamus.Results:Compared with the NG,the AWR score increased significantly and the OFT and EPM scores dropped significantly in the MG (all P＜0.05),and the expressions of hypothalamic CRF and CRFR1 proteins and mRNAs increased significantly (all P＜0.01).Compared with the MG and SHPMG,the AWR score dropped significantly and the OFT and EPM scores increased significantly in the HPMG (all P＜0.01),and the expressions of hypothalamic CRF and CRFR1 proteins and mRNAs decreased significantly (all P＜0.05).There were no significant differences between the MG and the SHPMG (all P＞0.05).Conclusion:HPM can down-regulate the abnormally increased expressions of CRF and CRFR1 proteins and mRNAs in hypothalamus of the TNBS-induced experimental colitis rats,which is plausibly one of its action mechanisms in mitigating visceral pain and the pain-related emotions in the experimental colitis rats.

<p><b>OBJECTIVE</b>To summarize the echocardiographic features of a wide spectrum of congenital mitral valve anomalies.</p><p><b>METHODS</b>The medical records, echocardiograms, cardiac catheterization studies, and surgical reports were reviewed. The mitral valve anomalies evaluated in the study included parachute mitral valve, double orifice mitral valve, congenital mitral stenosis with 2 papillary muscles, anomalous papillary muscle rotation, and 3 commissures and papillary muscles in 15 cases. Surgeries were performed in 11 patients, and 1 patient underwent transcatheter closure of the patent ductus arteriosus.</p><p><b>RESULTS</b>The echocardiograms of 6 cases of parachute mitral valve were characterized by a hypoplastic mitral valve with short chordal attachments to a single posterior medial papillary muscle. The mitral valve demonstrated restricted motion. The double orifice mitral valve were featured by two separate mitral valve orifice, with each suborifice supported by its own tension apparatus in 4 patients. Asymmetric hypoplastic mitral valve stenosis with two papillary muscles was found in 1 patient with short and unbalanced chordal attachments to the anterior lateral major papillary muscle. Anomalous papillary muscle rotation was found in 1 patient. Mirtal anomaly with 3 major commissures and 3 papillary muscles was found in 3 patients.</p><p><b>CONCLUSIONS</b>Echocardiography offers clear demonstration of the mitral valve thickness and chordal attachments, and allows visualization of the position and the number of the papillary muscles and interpapillary spaces for evaluation of the mobility of the valve leaflets, therefore can be a valuable diagnostic modality for congenital mitral valve anomalies, especially congenital mitral stenosis.</p>

<p><b>OBJECTIVE</b>To study the changes of platelet in May-Hegglin anomaly (MHA) and the molecular pathogenesis mechanism.</p><p><b>METHODS</b>Peripheral blood was drawn from the MHA proband, her father and her uncle. Platelet count and morphology were examined by automatic blood cell counter and microscopy, respectively. The platelet membrane protein was examined by flow cytometry. Membrane antibodies were determined by ELISA. PCR was used to amplify the exons 25, 31 approximately 32, 38 and 40 of the MYH 9 gene in the MHA patient and her diseased father. Furthermore, PCR products were sequenced, a specific point mutation was identified and inclusions (Dohle's body) in the neutrophil was detected by indirect immunofluorescence technique.</p><p><b>RESULTS</b>It was proved that in MHA patients, platelet count was higher by cell counter than by microscope (P < 0.01). Giant platelet was 94% but platelet membrane proteins (CD41, CD61, CD42A, CD42b) were in normal range. Membrane antibodies was undetectable. An A5521G mutation (GAG-->AAG) in the exon 38 was found in the proband and her diseased father, resulting in a characteristic change of NMMHC-A1841 (Glutamic acid-->Arginine), which was not found in other members of the family and in normal controls. Spindle-like inclusions with fluorescence were clearly displayed in neutrophil cytoplasm.</p><p><b>CONCLUSION</b>The molecular pathogenesis mechanism of May-Hegglin anomaly is the mutation in MYH 9 gene.</p>
