The signaling pathways involved in acupuncture intervention in post-stroke depression (PSD) mainly include cAMP signaling pathway, MAPK signaling pathway, PI3K/Akt/mTOR signaling pathway, NF-κB signaling pathway, CREB signaling pathway, and CaMK signaling pathway. A variety of regulatory networks are formed between these signaling pathways, which play a key role in reducing inflammation, inhibiting apoptosis, improving neuroplasticity, promoting angiogenesis, and protecting neurons.

Acupuncture has a certain effect for the patients with post-stroke depression. In clinics, acupuncture treat this disease from the brain, liver and kidney, heart and spleen, and phlegm and blood stasis. Acupuncture plays a role in nourishing the bone of marrow, regulating the liver and kidney, nourishing the heart and mind, and invigorating the spleen and stomach. Acupuncture plays an antidepressant role by regulating neurotransmitters and receptors, promoting nerve function repair, inhibiting the secretion of inflammatory factors, reducing inflammatory response, inhibiting the hyperfunction of hypothalamic-pituitary-adrenal axis, and regulating the brain-gut axis.

Objective To study the effect of low concentrations of sodium fluoride on the osteogenic/odontogenic differentiation of human dental pulp cells(hDPCs)in vitro.Methods This study was reviewed and approved by the Ethics Committee.hDPCs were cultured using a modified tissue explant technique in vitro.The effects of different con-centrations of sodium fluoride on the proliferation of hDPCs were measured by methylthiazol tetrazolium(MTT)assay.Appropriate concentrations were added to the osteogenic/odontogenic differentiation induction medium,and the cells were induced in vitro.Alizarin red S staining was used to detect the osteoblastic/odontogenic differentiation ability of the cells,and the mRNA expression of the key differentiation factors was detected by RT-qPCR.Moreover,the expres-sion of key molecules of endoplasmic reticulum stress(ERS)was detected by RT-qPCR and Western blot.The data were analyzed with the SPSS 18.0 software package.Results Low concentration of NaF(0.1 mmol/L)could stimulate cell proliferation in vitro,while a high concentration(5-10 mmol/L)could inhibit cell proliferation(P＜0.05).According to the literature and the experimental data,0.1 mmol/L NaF was selected as the following experimental concentration.The levels of alizarin red S staining were increased after NaF induction of mixed osteogenic/odontogenic differentiation in vi-tro.The mRNA expression levels of key molecules for osteogenic/odontogenic differentiation,dentin sialophosphoprotein(DSPP),bone sialoprotein(BSP)and osteocalcin(OCN),were increased(P＜0.05).The mRNA levels of ERS markers(splicing x-box binding protein-1(sXBP1),glucose-regulated protein 78(GRP78)and activating transcription Factor 4(ATF4)were increased in NaF-treated cells.The protein expression levels of key ER stress molecules(phosphorylated RNA-activated protein kinase-like ER-resident kinase(p-PERK),phosphorylated eukaryotic initiation factor-2α(p-eIF2α)and ATF4)were higher in NaF-treated cells.Conclusion A low concentration of NaF promotes the osteogenic/odontogenic differentiation of hDPCs and increases the level of ER stress.

Objective To explore the correlation between serum microRNA-29a-3p(miR-29a-3p),throm-bospondin 2(THBS2)and cardiopulmonary function in children with chronic pulmonary heart disease.Meth-ods A total of 136 children with chronic pulmonary heart disease treated in Shijiazhuang Hospital of Tradi-tional Chinese Medicine from July 2019 to September 2023 were selected as the study subjects.Based on their clinical signs,cardiopulmonary function,and symptoms,they were divided into a compensated group(74 ca-ses)and a decompensated group(62 cases).Real-time fluorescence quantitative PCR(RT-qPCR)method was applied to detect serum miR-29a-3p level,and enzyme-linked immunosorbent assay(ELISA)was applied to detect serum THBS2 level.Moreover,ultrasound diagnostic equipment was applied to detect cardiac function indicators such as left ventricular ejection fraction(LVEF)and cardiac output(CO).Creatine kinase isoenzyme(CK-MB)and troponin(cTnl)were detected by electroluminescence analysis.Pulmonary function indicators were detected by pulmonary artery systolic pressure(PASP),mean pulmonary artery pressure(MPAP)and pulmonary artery diastolic pressure(PADP).Pearson correlation was used to analyze the corre-lation between serum miR-29a-3p and THBS2 levels and cardiopulmonary function indexes in children with chronic pulmonary heart disease,and multivariate Logistic regression analysis was used to screen the influen-cing factors of the disease in children with chronic pulmonary heart disease.Receiver operating characteristic(ROC)curve was drawn to analyze the evaluation value of serum miR-29a-3p and THBS2 levels in children with chronic pulmonary heart disease.Results The THBS2,CK-MB,cTnI,PASP,MPAP,and PADP in the decompensated group were higher than those in the compensated group(P＜0.05),while miR-29a-3p,LVEF,and CO were lower than those in the compensated group(P＜0.05).Serum miR-29a-3p in children with chro-nic pulmonary heart disease was positively correlated with LVEF and CO(P＜0.05),but negatively correla-ted with CK-MB,cTnI,PASP,MPAP,and PADP(P＜0.05).THBS2 was negatively correlated with LVEF and CO(P＜0.05),but positively correlated with CK-MB,cTnI,PASP,MPAP,and PADP(P＜0.05).MiR-29a-3p was a protective factor for exacerbation of chronic pulmonary heart disease in children(P＜0.05),while THBS2 was an independent risk factor for exacerbation of chronic pulmonary heart disease in children(P＜0.05).ROC curve analysis results showed that the area under the curve(AUC)of serum miR-29a-3p and THBS2 levels alone and in combination for evaluating the severity of chronic pulmonary heart disease in children were 0.827,0.817 and 0.915,respectively.Conclusion Serum miR-29a-3p and THBS2 levels are both factors affecting the disease of children with chronic pulmonary heart disease,and are closely related to the disease and cardiopulmonary function of children with chronic pulmonary heart disease.

Objective:To analyze the clinical features of children with refractory N-methyl-D-aspartate (NMDA) receptor antibody encephalitis treated with tocilizumab.Methods:Demographic and clinical manifeatations, immunotherapy and prognosis data of 9 children with refractory NMDA receptor antibody encephalitis who received tocilizumab in the Department of Pediatrics Neurology, XiangYa Hospital of Central South University from August 2021 to September 2023 were collected retrospectively. Prognosis was evaluated using the modified Rankin scale at initial diagnosis, at the initiation of tocilizumab treatment, and at the last follow-up. Treatment related complications, neuroimaging, and electroencephalography data were analyzed.Results:Among the 9 children, 6 were male and 3 were female, with an onset age of 4.2 (2.8, 8.7) years. At the onset of the disease, 9 children had a modified Rankin scale score of 5. When tocilizumab treatment was initiated, 7 children had a score of 5, and 2 children had a score of 4. The interval between the onset and initiation of tocilizumab treatment was 12 (5, 27) months, and the treatment frequency was 8 (5, 13) times. The follow-up time was 2.8 (1.5, 3.7) years. At the last follow-up, the symptoms of 9 children, including movement disorder, sleep disorder, consciousness disorder, silence and autonomic dysfunction, were improved to varying degrees, and none of them had seizures. At the last follow-up, 4 cases with a modified Rankin scale score of 0, 1 case with a score of 1, 2 cases with a score of 3, 1 case with a score of 4 and 1 case with a score of 5. The modified Rankin scale at the last follow-up was significantly different from that at the start of tocilizumab ( Z=-2.56, P=0.014). All children had no serious adverse reactions during the treatment. Conclusions:After treatment with tocilizumab, the symptoms in patients with refractory NMDA receptor antibody encephalitis, including movement disorder, sleep disorder, consciousness disorder, silence and autonomic dysfunction were improved, and none of them had seizures. The modified Rankin scale were improved, and the safety was good.

Objectives: To explore and summarize the beneficial effects of a traditional Chinese medicine prepara-tion, Tripterygium glycosides tablets (TGT), in rheumatoid arthritis (RA) animal models of neo-vascularization, and to provide a reference for future clinical applications and research on its pharmacologic mechanism.Methods: We searched the databases PubMed, Embase, Web of Science, Chinese National Knowledge Infrastructure, VIP, Wan Fang and SinoMed (China Biomedical Document Service System) to identify studies of TGT with outcome indicators of angiogenesis-related factors that were published before April 2020. Subgroup analysis and meta-regression were performed for dosage and duration of TGT. Statistical tests and subgroup analysis were conducted using RevMan 5.3, and meta-regression and sensitivity analysis were conducted using STATA/SE 15.0. Results: Fourteen studies of TGT in RA rats were included in this analysis. Treatment with TGT signifi-cantly reduces synovial microvessel density and the expression of vascular endothelial growth factor (VEGF), VEGF receptor 2, hypoxia inducible factor α, c-Fos, c-Jun, angiopoietin-1 and angiopoietin-2 compared with control groups (P < .05). Subgroup analysis did not show a significant association of the mRNA levels of VEGF in synovium, assessed using quantitative real-time PCR, with duration or dosage of TGT. Meta-regression analysis also indicated that the effects of dosage and duration were not significantly associated with differences in VEGF mRNA levels. Sensitivity analysis on VEGF mRNA levels did not fundamentally change the results. Conclusions: TGT can reduce synovial neovascularization by decreasing synovial microvessel density and expression of VEGF, VEGF receptor 2, hypoxia-inducible factorα, c-Fos, c-Jun, Ang-1 and Ang-2, thereby suppressing pannus formation and bone destruction in rat models of RA. Additional well-designed studies are required to confirm these findings.

Objective To evaluate the effect of combination of uterine artery chemoembolization and curettage in treatment of caesarean scar pregnancy(CSP),and to analyze the possible influence factors.Methods 46 cases with caesarean scar pregnancy treated by the combination of uterine artery chemoembolization and curettage were retrospectively analyzed.Univariate analysis was made on the factors that might influence the efficacy,and the Logistic regression model was constructed for the significant variables.Results All of the patients were terminated pregnancy succesfully .According to the ultrasound recheck,there were no residual gestational sac tissue in 29 patients,and some residual gestational sac tissue in 17 patients.After the application of traditional Chinese medicine or methotrexate and other symptomatic treatment, the pregnancy was terminated.The univariate analysis showed that the number of cesarean section,the gestational sac volume,the gestational weeks,the type of CSP,and the condition of the fetal heart pulsation were related to the presence of residues in the uterus after treatment (P＜0.05).The multivariate analysis showed that gestational sac volume ＞9 cm3 ,gestational weeks ＞ 7 weeks and exogenous CSP were the independent factors leading to intrauterine residual gestational sac tissue.Conclusion Uterine artery chemoembolization combined with curettage is an effective method for treatment of caesarean scar pregnancy.It is proposed that clinical treatment should pay close attention to the factors that may affect the efficacy.
