Objective:To investigate the clinical efficacy of acupoint pressing acupuncture combined with moxibustion at Baihui acupoint on infantile cold and nasal obstruction caused by exogenous wind and cold. Methods:This study included a total of 120 children with exogenous wind and cold-induced infantile cold and nasal obstruction who were treated at the Jinhua Maternal & Child Health Care Hospital from February 2021 to May 2022. They were divided into three groups using a random number table method, namely the acupoint pressing acupuncture group, the moxibustion group, and the combined therapy group, each containing 40 children. Based on routine treatment, children in the acupoint pressing acupuncture group received acupoint ( Yintang, Shuangyingxiang, Shuangbitong) pressing acupuncture treatment, while those in the moxibustion group underwent mild moxibustion at Baihui acupoint, and those in the combined therapy group underwent acupoint ( Yintang, Shuangyingxiang, Shuangbitong) pressing acupuncture Baihui combined with mild moxibustion at Baihui acupoint. The clinical efficacy of each group was evaluated. At 2, 24, 48, and 72 hours after treatment, differences in nasal congestion symptom scores were compared among the three groups. Sleep quality was also compared among the three groups before and after treatment. Results:The response rate in the combined therapy group was 92.5% (37/40), which was significantly higher than 75% (30/40) in the acupoint pressing acupuncture group and 65% (26/40) in the moxibustion group ( χ2 = 4.50, 9.04, both P < 0.05). At 2, 24, 48, and 72 hours after treatment, the nasal congestion symptom score in the combined therapy group was (2.05 ± 0.55) points, (1.80 ± 0.64) points, (1.33 ± 0.59) points, and (0.90 ± 0.18) points, respectively, while it was (2.43 ± 0.59) points, (2.15 ± 0.57) points, (1.73 ± 0.84) points, and (1.18 ± 0.80) points, respectively, in the acupoint pressing acupuncture group, and (2.50 ± 0.59) points, (2.13 ± 0.78) points, (1.88 ± 0.81) points, and (1.45 ± 0.81) points, respectively, in the moxibustion group. At the above-mentioned time points, the nasal congestion symptom score was statistically significant among the three groups ( F = 3.15, 9.27, 16.17, 20.22, all P < 0.05). After treatment, daytime sleep duration and nocturnal sleep duration in the combined therapy group were (3.41 ± 0.31) hours and (12.36 ± 1.17) hours, respectively, which were significantly longer than (2.95 ± 1.07) hours and (11.33 ± 1.38) hours in the acupoint pressing acupuncture group and (2.93 ± 0.98) hours and (11.21 ± 1.93) hours in the moxibustion group ( F = 6.37, 12.31, both P < 0.05). Nocturnal wake time, the number of night wakings, and sleep onset time in the combined therapy group were (18.74 ± 2.21) minutes, (1.64 ± 0.18) times, and (15.43 ± 2.03) minutes, respectively, which were significantly shorter or less than (21.13 ± 3.78) minutes, (2.15 ± 0.66) times, and (17.63 ± 5.24) minutes in the acupoint pressing acupuncture group, and (20.53 ± 2.90) minutes, (2.11 ± 0.32) times, and (17.22 ± 2.88) minutes in the moxibustion group ( F = 15.93, 15.36, 10.11, all P < 0.05). There was a significant difference in sleep quality score among the three groups ( F = 23.45, P < 0.05). Conclusion:The combination of acupoint pressing acupuncture and moxibustion at Baihui acupoint is highly effective against infantile cold and nasal obstruction caused by exogenous wind and cold. The combined therapy can alleviate the symptoms of nasal congestion in children and improve sleep quality.

Objective To screen the pharmacodynamic material basic components of Artemisiae Annuae Herba and study its antioxidant activity in vitro by investigating the spectrum-effect relationship between the HPLC fingerprints of 11 batches of Artemisiae Annuae Herba(dried aerial part of Artemisia annua L.).Methods The determination was performed on Aglient C18 column(250 mm×4.6 mm,5 μm)with mobile phase consisted of 0.2%phosphoric acid solution-Methanol(gradient elution)at the flow rate of 1.0 ml/min.The column temperature was indoor temperature,and detection wavelength was 220 nm,with sample size of 10 μl.Using isochlorogenic acid A as reference,HPLC fingerprints of 11 batches of samples were determined.The common peaks of 11 batches of samples were identified and recorded through TCM chromatographic fingerprint similarity evaluation system(2012 edition).Using scavenging rate of DPPH and ABTS free radical as pharmacodynamic indicators of antioxidant effects,SIMCA 14.1 analysis software was used for PLSR to establish the spectra-effect relationship.Results There were 48 common peaks on 11 batches of sample,11 components were identified as scopoletin,scoparone,isochlorogenic acid B,A,C,luteolin,apigenin,chrysosplenetin,artemisinin,artemisetin and artemisinic acid.The scavenging activity of 11 batches of samples to DPPH and ABTS free radicals was detected.The spectrum-effect relationship showed that isochlorogenic acid A,B,C and scoparone were positively associated with its antioxidant capacity,and variable projection value was greater than 1.It was suggested that these components were the material basis of antioxidant effect in Artemisiae Annuae Herba.Conclusion This study investigates the antioxidant capacity of different substances in Artemisiae Annuae Herba in vitro,and proves that isochlorogenic acid A,B,C and scoparone play a major role for the antioxidant capacity.

Objective To explore the effect of Bajitianwan(BJTW)formula on bone formation of Aβ-injured osteoblasts and its mechanism.Methods Osteoblasts isolated from neonatal 24-hour Wistar rats were used for the study,and osteoblasts were subjected to damage with Aβ1-42 oligomers,and pharmacological intervention was performed with the aqueous extract of BJTW formula.The MTT assay,alkaline phosphatase(ALP)activity assay,catalase(CAT)activity assay,superoxide dismutase(SOD)activity assay,glutathione(GSH)activity assay and malondialdehyde(MDA)activity assay were carried out respectively.The expression levels of bone morphogenetic protein 2(BMP2),osteogenic specific transcription factor(RUNX-2)and osteoprotective protein(OPG)were detected by Western blotting.After confirming the effect of BJTW formula on Aβ-injured osteoblasts,the network pharmacology method was used to predict the potential pathways.Results The BJTW formula significantly promoted the proliferation of Aβ-injured osteoblasts,increased ALP,SOD and GSH activity,inhibited MDA activity,and promoted the expression of bone formation-related proteins BMP2,RUNX-2 and OPG.Network pharmacological analysis showed that the effect of ameliorating of Aβ-injured osteoblasts by BJTW formula was mainly mediated by AGE-RAGE,PI3K-Akt,MAPK and neuroactive ligand-receptor interaction signaling pathways.Conclusion In this study,the effect of BJTW formula on improving the osteoblasts damaged by Aβ was confirmed for the first time,and its related mechanism was explored based on network pharmacology method.The results lay a strong foundation for the clinical application of traditional formula BJTW against osteoporosis.

Objective To explore the relationship between serum microRNA-124(miR-124),CD146,angio-poietin-like protein 2(Angptl2)and the stability of carotid atherosclerosis(CAS)plaque in patients with a-cute cerebral infarction(ACI),and to provide reference for early prevention and treatment of patients with ACI.Methods A total of 191 patients with ACI admitted in Handan Central Hospital from January 2020 to February 2023 were selected as ACI group,and another 61 healthy volunteers who were underwent physical examination during the same period were selected as control group.The patients with ACI were divided into unstable plaque group(56 cases),stable plaque group(71 cases),and non plaque group(64 cases)based on carotid color doppler ultrasound results.The serum miR-124 expression levels of all subjects were detected by real time fluorescence quantitative polymerase chain reaction(RT-qPCR),and the serum CD146 and Angptl2 levels were detected by enzyme-linked immunosorbent assay(ELISA).The influencing factors of the instabili-ty of CAS plaque in patients with ACI was analyzed by univariate and multivariate Logistic regression.The predictive value of serum miR-124,CD146 combined with Angptl2 for the instability of CAS plaque in patients with ACI was analyzed by the receiver operating characteristic(ROC)curve.Results The serum CD146 and Angptl2 levels in ACI group were higher than those in control group(P＜0.05),and the miR-124 expression level was lower than that in control group(P＜0.05).Univariate analysis showed that the stability of CAS plaques in ACI patients was correlated with age,hypertension,hyperlipidemia,fibrinogen(FIB),serum C-reac-tive protein(CRP),serum cystatin C(CyC),CD146,Angptl2 and miR-124(P＜0.05).Multivariate Logistic regression analysis showed that the decrease of serum miR-124,the increase of CD146,the increase of Angptl2 and the combination of hyperlipidemia were risk factors for CAS plaque stability in ACI patients(P＜0.05).The area under ROC curve(AUC)of serum miR-124,CD146,Angptl2 and the combination of the three indi-cators to predict CAS plaque instability in ACI patients were 0.741,0.719,0.781 and 0.834,respectively.Conclusion The serum miR-124 expression level,CD146 and Angptl2 levels are the influencing factors of CAS plaque instability in ACI patients,which may be involved in the formation and development of CAS plaque in ACI patients.The combined detection of the three factors has a good predictive effect on CAS plaque instability in ACI patients.

As a complex and large microbial community colonized in the human body, the intestinal flora and its metabolites short-chain fatty acids (SCFAs) play an important role in participating in human metabolism, resisting pathogens, and regulating immune mechanisms. In recent years, many studies have found that the intestinal flora is closely related to bone metabolism. The intestinal flora is able to regulate bone metabolism and affect bone mass changes through various pathways such as absorption of nutrition, generation of SCFAs, regulation of immunity, and influence on body metabolism. The potential pathways and mechanisms by which intestinal flora affect bone mass changes were reviewed in this article in bone metabolism. The related study on Traditional Chinese Medicine that has effects in balancing intestinal flora for regulating bone metabolism was also introduced in order to provide new ideas for the prevention and treatment of osteoporosis, a disease related to bone metabolism.
