To investigate the mechanism of moxibustion in regulating cellular apoptosis in rat's precancerous lesion of primary hepatocellular carcinoma (HCC). Methods:Seventy-four rats were randomly allocated to normal group,model group and moxibustion group,and the diethylic nitrosamine (DEN) was used to establish HCC model. Moxibustion with moxa cone which is as big as a grain of wheat was performed on acupoint Zusanli (ST 36),3 cones for each acupoint and 0.5 mg for each cone,the treatment was given once a day,totally 16 weeks. Then the changes in the body weight,liver weight and thymus weight,a morphological change in the liver tissue and changes in γ-GT and GST were observed;Immunohistochemical staining method was adopted to observe the tendency of changes in relevant apoptosis genes such as C-myc,N-ras and mutant type P53,and the influence of moxibustion on cell cycle modulation genes such as cyclinD1,CDK4 and p16. Results:Moxibustion could reduce the activities of γ-GT and GST in the blood,obviously decrease the protein expression of relevant apoptosis genes such as C-myc,N-ras and mutant type P53 and markedly inhibit the over-expression of relevant cell cycle modulation genes such as cyclinD1 and CDK4 and the mutation of cell cycle modulation gene p16. Conclusion:Moxibustion might play a certain role in relieving HCC precancerous lesion and its action mechanism might be related to the regulation on partial apoptosis genes.

OBJECTIVE:To provide reference for ensuring safe and effective drug use in obstetrics and gynecology outpatient department.METHODS:Medication education intervention was conducted among some patients in obstetrics and gynecology outpatient department from 4 third grade class A hospitals of our province through making Wechat pushing messages,videos and leaflets.The difference of rational drug use knowledge awareness and compliance was compared before and after intervention by questionnaire survey.RESULTS:A total of 60 questionnaires were distributed,and 60 valid questionnaires were collected with effective recovery rate of 100％.Compared to before intervention,correct rate of 20 questions about the knowledge of rational drug use were improved after intervention in respects of awareness and compliance.The awareness and compliance scores about the knowledge of rational drug use after intervention were higher than before intervention;there was statistical significance in Wechat pushing message group [(53.18 ± 11.51) vs.(88.48 ± 7.12),(55.15 ± 11.82)vs.(86.81 ± 7.69)],in video group [(49.50 ± 17.23) vs.(85.00 ± 11.55),(52.00 ± 17.70)vs.(86.00 ± 6.99)],in leaflets group[(41.47 ± 9.14)vs.(77.05 ± 9.36),(43.23 ± 10.89)vs.(78.82 ± 9.11)] be-fore and after intervention (P＜0.05).There was no statistical significance in the improvement of awareness or compliance score among those groups (P=0.992 and P=0.397).CONCLUSIONS:Three intervention methods can effectively improve the awareness and compliance of patients about rational drug use knowledge in obstetrics and gynecology outpatient department.Pharmacists can choose the appropriate medication education intervention based on the patient's different educational levels,preferences and acceptability.

Background: Galangin, commonly employed in traditional Chinese medicine for its diverse medicinal properties, exhibits potential in treating inflammatory pain. Nevertheless, its mechanism of action remains unclear. Methods: Mice were randomly divided into 4 groups for 7 days: a normal control group, a galangin-treated (25 and 50 mg/kg), and a positive control celecoxib (20 mg/kg). Analgesic and anti-inflammatory effects were evaluated using a hot plate test, acetic acid-induced writhing test, acetic acid-induced vascular permeability test, formalininduced paw licking test, and carrageenan-induced paw swelling test. The interplay between galangin, transient receptor potential vanilloid 1 (TRPV1), NF-κB, COX-2, and TNF-α proteins was evaluated via molecular docking. COX- 2, PGE2, IL-1β, IL-6, and TNF-α levels in serum were measured using ELISA after capsaicin administration (200 nmol/L). TRPV1 expression in the dorsal root ganglion was analyzed by Western blot. The quantities of substance P (SP) and calcitonin gene-related peptide (CGRP) were assessed using qPCR. Results: Galangin reduced hot plate-induced licking latency, acetic acid-induced contortions, carrageenantriggered foot inflammation, and capillary permeability in mice. It exhibited favorable affinity towards TRPV1, NF- κB, COX-2, and TNF-α, resulting in decreased levels of COX-2, PGE2, IL-1β, IL-6, and TNF-α in serum following capsaicin stimulation. Galangin effectively suppressed the upregulation of TRPV1 protein and associated receptor neuropeptides CGRP and SP mRNA, while concurrently inhibiting the expression of NF-κB, TNF-α, COX-2, and PGE2 mRNA. Conclusions Galangin exerts its anti-inflammatory pain effects by inhibiting TRPV1 activation and regulating COX-2, NF-κB/TNF-α expression, providing evidence for the use of galangin in the management of inflammatory pain.

Objective:To assess the clinical features and effectiveness of antiviral therapy in newborns with sensorineural hearing loss (SNHL) caused by congenital congenital cytomegalovirus (cCMV) infection, and to speculate the risk factors for poor hearing outcomes.Methods:A multicenter prospective cohort study wasconducted, enrolling 176 newborns diagnosed with cCMV at four research centers in Zhejiang Province from March 1, 2021, to April 30, 2024. Clinical characteristics at birth were recorded and hearing was followed up. The children were divided into groups based on their condition at birth, specifically into asymptomatic, mild symptom, and moderate to severe symptom groups. Additionally, they were divided into SNHL and normal hearing groups based on the results of air conduction brainstem audiometry at birth. And they were also divided into treatment and untreated groups according to antiviral treatment. Mann Whitney U test, and chi square test were used for inter group comparison to analyze the differences in clinical features between different disease groups, and to analyze the effects of clinical features, antiviral therapy, and other factors on hearing improvement. Logistic regression analysis was employed to identify the risk factors influencing hearing outcomes. Results:Among the cohort of 176 children diagnosed infection with cCMV, 90 cases were male and 86 cases were female. Of these, 79 cases were asymptomatic, 12 cases classified as mild cCMV and 85 cases as moderate to severe cCMV. Fifty cases belonged to SNHL group, with different degrees of severity, including 30 cases of mild, 9 cases of moderate, 5 cases of severe, and 6 cases of extremely severe SNHL. Among the 121 cases in the normal hearing group, 2 cases (1.7%) exhibited late-onset hearing loss despite having normal hearing at birth. Among 81 cases (46.0%) who completed the hearing follow-up, 71 cases (87.7%) had good hearing outcomes and 10 cases (12.3%) had poor hearing outcomes. Among the 81 children, 29 cases (35.8%) had SNHL at birth. During follow-up, the hearing threshold improved in 19 cases (65.5%), remained stable in 7 cases (24.1%) and progressed in 3 cases (10.3%). A total of 26 cases in the treatment group and 55 cases in the untreated group completed the hearing follow-up assessment. The rate of hearing improvement in the treatment group was found to be higher compared to the untreated group (13 cases (50.0%) vs. 6 cases (10.9%), χ2=15.00, P<0.01), with individuals in the treatment group having a 4.58 times greater likelihood of experiencing hearing improvement ( RR=4.58,95% CI 1.96-10.70, P<0.05). However, no statistically significant difference was observed in hearing outcomes between the antiviral treatment group and the untreated group ( RR=0.90, 95% CI 0.57-1.41, P=0.517). Multivariate analysis further confirmed SNHL ( OR=11.58, 95% CI 2.10-63.93, P=0.005) and preterm birth ( OR=4.98, 95% CI 1.06-23.41, P=0.042) as independent risk factors for poor hearing outcomes. Conclusions:SNHL resulting from cCMV infection presents symptoms at birth and can be improved by antiviral therapy. Poor hearing outcomes are associated with SNHL and prematurity.
