OBJECTIVE: To determine the effectiveness of pediatric Tuina(PT) in preventing recurrent acute respiratory tract infections(ARTIs) in children. METHODS: This is a retrospective cohort study based on the electronic medical records of children with recurrent ARTIs in 2016. Children were divided into a PT group or a non-PT group, according to whether they had received PT or not in 2016. The primary outcome was the number of ARTI episodes in 2017 and 2018. The secondary outcomes were the number of ARTIs leading to outpatient department visits and outpatient antibiotic prescriptions due to ARTIs in the same time period. Negative binomial regressions were used to detect the association between PT and the outcomes. RESULTS: A total of 2303 children were included in the analysis, including 94 in the PT group and 2209 in the non-PT group. Children who received PT six or more times in 2016 had fewer episodes of ARTIs in 2017 [incidence rate ratio(IRR): 0.59, 95% confidence interval(CI)(0.42-0.84)] and 2018 [IRR: 0.58, 95% CI(0.36-0.94)] and fewer outpatient department visits due to ARTIs in 2017 [IRR: 0.56, 95% CI(0.38-0.83)] than children who had not received PT in 2016. There was no significant difference in the number of outpatient antibiotic prescriptions between the two groups. CONCLUSIONS: Receiving PT six or more times within one year is associated with a decrease in recurrent ARTIs in children in the following two years. Randomized controlled trials are needed for effect evaluation prior to establishing PT as a method for preventing recurrent ARTIs among children.

To the Editor:Gestational diabetes mellitus(GDM)is a pathologic condition in which glucose intolerance and insulin resistance develop to different degrees during pregnancy.Women with GDM have higher odds of adverse maternal and fetal outcomes.Patients with a history of GDM were at a significantly increased risk for recurrence of GDM in subsequent pregnancies.Our previous and some other studies found an increased incidence of adverse perinatal outcomes in pregnant with recurrent GDM.^([1])So far,women with a prior history of GDM are not recommended to refrain from subsequent pregnancy in light of the limited available data.What about those women with a history of recurrent GDM?Should women with recurrent GDM be recommended to avoid further pregnancy?Currently,studies on perinatal outcomes of women with re-recurrent GDM and their prognostic factors are very rare.Therefore,this retrospective cohort study was performed to explore perinatal outcomes of pregnant woman with re-recurrent GDM and their prognostic factors.

Upregulation of vascular endothelial growth factor A/basic fibroblast growth factor(VEGFA/b FGF)expression in the penumbra of cerebral ischemia can increase vascular volume,reduce lesion volume,and enhance neural cell proliferation and differentiation,thereby exerting neuroprotective effects.However,the beneficial effects of endogenous VEGFA/b FGF are limited as their expression is only transiently increased.In this study,we generated multilayered nanofiber membranes loaded with VEGFA/b FGF using layer-by-layer self-assembly and electrospinning techniques.We found that a membrane containing 10 layers had an ideal ultrastructure and could efficiently and stably release growth factors for more than 1 month.This 10-layered nanofiber membrane promoted brain microvascular endothelial cell tube formation and proliferation,inhibited neuronal apoptosis,upregulated the expression of tight junction proteins,and improved the viability of various cellular components of neurovascular units under conditions of oxygen/glucose deprivation.Furthermore,this nanofiber membrane decreased the expression of Janus kinase-2/signal transducer and activator of transcription-3(JAK2/STAT3),Bax/Bcl-2,and cleaved caspase-3.Therefore,this nanofiber membrane exhibits a neuroprotective effect on oxygen/glucose-deprived neurovascular units by inhibiting the JAK2/STAT3 pathway.

Objective:To develop an interference-free and rapid method to elucidate GuanxinⅡ(GXⅡ)'s representative vasodilator absorbed bioactive compounds(ABCs)among enormous phytochemicals.Methods:The contents of ferulic acid,tanshinol,and hydroxysafflor yellow A(FTA)in GXⅡ/rat serum after the oral administration of GXⅡ(30 g/kg)were detected using ultra-performance liquid chromatography-mass spectrometry.Totally 18 rats were randomly assigned to the control group(0.9%normal saline),GXⅡ(30 g/kg)and FTA(5,28 and 77 mg/kg)by random number table method.Diastolic coronary flow velocity-time integral(VTI),i.e.,coronary flow or coronary flow-mediated dilation(CFMD),and endothelium-intact vascular tension of isolated aortic rings were measured.After 12 h of exposure to blank medium or 0.5 mmol/L H_(2)O_(2),endothelial cells(ECs)were treated with post-dose GXⅡof supernatant from deproteinized serum(PGSDS,300μL PGSDS per 1 m L of culture medium)or FTA(237,1539,and 1510 mg/m L)for 10 min as control,H_(2)O_(2),PGSDS and FTA groups.Nitric oxide(NO),vascular endothelial growth factor(VEGF),endothelin-1(ET-1),superoxide dismutase(SOD),malondialdehyde(MDA)and phosphorylated phosphoinositide 3 kinase(p-PI3K),phosphorylated protein kinase B(p-AKT),phosphorylated endothelial nitric oxide synthase(p-e NOS)were analyzed.PGSDS was developed as a GXⅡproxy of ex vivo herbal crude extracts.Results:PGSDS effectively eliminates false responses caused by crude GXⅡpreparations.When doses equaled the contents in GXⅡ/its post-dose serum,FTA accounted for 98.17%of GXⅡ-added CFMD and 92.99%of PGSDS-reduced vascular tension.In ECs,FTA/PGSDS was found to have significant antioxidant(lower MDA and higher SOD,P<0.01)and endothelial function-protective(lower VEGF,ET-1,P<0.01)effects.The increases in aortic relaxation,endothelial NO levels and phosphorylated PI3K/Akt/e NOS protein induced by FTA/PGSDS were markedly abolished by NG-nitro-L-arginine methyl ester(L-NA,e NOS inhibitor)and wortmannin(PI3K/AKT inhibitor),respectively,indicating an endothelium-depende

The gut is the largest digestive and absorptive organ,which is essential for induction of mucosal and systemic immune responses,and maintenance of metabolic-immune homeostasis.The intestinal components contain the epithelium,stromal cells,immune cells,and enteric nervous system(ENS),as well as the outers,such as gut microbiota,metabolites,and nutrients.The dyshomeostasis of intestinal microenvironment induces abnormal intestinal development and functions,even colon diseases including dysplasia,inflammation and tumor.Several recent studies have identified that ENS plays a crucial role in maintaining the immune homeostasis of gastrointestinal(GI)microenvironment.The crosstalk between ENS and immune cells,mainly macrophages,T cells,and innate lymphoid cells(ILCs),has been found to exert important regulatory roles in intestinal tissue programming,homeostasis,function,and inflammation.In this review,we mainly summarize the critical roles of the interactions between ENS and immune cells in intestinal homeostasis during intestinal development and diseases progression,to provide theoretical bases and ideas for the exploration of immunotherapy for gastrointestinal diseases with the ENS as potential novel targets.
