Objective To investigate the status of familial aggregation of Helicobacter pylori (Hp) infection in Jinniu District, Chengdu, and analyze its risk factors so as to provide a basis for developing prevention and control strategies of family aggregation of Hp infection. Methods A total of 172 subjects in the Second Affiliated Hospital of Chengdu Medical College · 416 Hospital of Nuclear Industry from January 2022 to January 2023 were selected as the research subjects. All subjects underwent 13C-urea breath test (13C-UBT) to diagnose whether there was Hp infection. Analyze the current situation of family aggregation of Hp infection in the region, collect general data of survey subjects, analyze the relevant factors affecting Hp family aggregation infection, and develop prevention and control strategies based on this. Results A total of 242 people from 97 households were surveyed, and the Hp family aggregation rate was 29.33%. Univariate analysis showed that there were statistically significant differences in family aggregation of Hp infection in terms of different age groups (χ²=9.719, P=0.008), marital status (χ²=8.496, P=0.014), occupations (χ²=19.462, P<0.001), frequencies of dining out (χ²=5.457, P=0.019), previous Hp test results (χ² =4.131, P=0.042) and test results after treatment (χ²=12.000, P=0.001), with statistical significance (P<0.05). Multivariate logistic regression analysis showed that the frequency of dining out 2 days or more per week and a positive Hp test results in the past were risk factors for family aggregation of Hp infection, while the occupation of teachers/medical staff/management/technology personnel and a negative Hp results after treatment were protective factors (P<0.05). Conclusion Family aggregation of Hp infection is related to family members' occupation, frequency of dining out, previous Hp test results and Hp test results after eradication, which deserves attention in clinical practice.

Objective To explore the molecular mechanism of Xiaojin Pills in the treatment of breast cancer using an integrated network pharmacology and experimental verification.Methods The chemical components and potential targets of Xiaojin Pills were obtained from TCMSP,TCM-ID,ETCM and SwissTargetPrediction databases.Breast cancer related targets were collected from GeneCards,OMIM and KEGG databases.The overlapped targets were imported into STRING database to analysis a protein-protein interaction(PPI).The key targets of PPI networks were screened based on node topology parameter values through Cytoscape 3.8.0.DAVID database was used to analyze the GO and KEGG pathway enrichment to build drug-chemical components-key targets-signaling pathway network.The breast cancer cell lines MDA-MB-231 and SK-BR-3 were used to study the effects of Xiaojin Pills extract on cell apoptosis,migration and invasion,and to verify the key pathway obtained by enrichment analysis.Results Totally 181 chemical components in Xiaojin Pills were obtained,including quercetin,myricetin,pinocembrin and β-sitosterol.615 potential targets were identified for the anti-breast cancer effects of Xiaojin Pills.After overlapping,170 key targets against breast cancer were identified based on the topological analysis,which included SRC,ERK1/2,AKT1,EGFR,etc.KEGG analysis enriched pathways including pathways in cancer,MAPK signaling pathway,endocrine resistance,PI3K-AKT signaling pathway,EGFR tyrosine kinase inhibitor resistance,apoptosis,and HIF-1 signaling pathway,which may play important roles in the therapeutic effects of Xiaojin Pills against breast cancer.GO enrichment was involved in protein phosphorylation,inflammatory response,negative regulation of apoptosis,and positive regulation of ERK1 and ERK2 cascades.Cell experiments showed that Xiaojin Pills further induced mitochondria-dependent apoptosis by inhibiting the activation of MAPK and PI3K-AKT pathways.At the same time,the expressions of ZO-1 and β-catenin increased,and the epithelial-mesenchymal transformation process was reversed to inhibit the metastasis of breast cancer cells.Conclusion The key targets and signaling pathways of Xiaojin Pills in the treatment of breast cancer are studied through network pharmacology combined with in vitro experiments,which provided a basis for further study of its pharmacodynamic material basis,mechanism of action and clinical application.

Perimenopausal syndrome （MPS）， a common endocrine system disease， is one of the diseases responding specifically to traditional Chinese medicine （TCM）. The China Association of Chinese Medicine organized experts in endocrinology， gynecology， and interdisciplinary fields of both Western and Chinese medicine to discuss the advantages and challenges of diagnosing and treating MPS with Western medicine， TCM， and integrative medicine. Experts at the conference believe that MPS is initiated by estrogen decline and rooted in deficiency， with the pathogenesis being imbalance between Yin and Yang in the kidney. The hormone replacement therapy in Western medicine for menopause can rapidly alleviate related symptoms by quickly restoring the estrogen level and timely detect and delay complications of menopause， whereas such a therapy has certain risks， necessitating close monitoring of adverse reactions. Moreover， the various contraindications and precautions limit the clinical application of the hormone replacement therapy. TCM has advantages in synergistically alleviating symptoms such as hot flashes， sweating， sleep disorders， and emotional abnormalities of MPS without causing obvious adverse reactions. However， its efficacy is slower than the hormone replacement therapy， and the TCM evidence for preventing and treating complications of menopause remains unclear. Three suggestions were proposed for the future development of both Western and TCM for ameliorating MPS. First， an integrated diagnosis and treatment system for MPS with both Western and Chinese medicine should be established. Second， high-quality evidence-based interventions for MPS should be developed with TCM alone or in combination with Western medicine. Third， efforts should be made to promote the new TCM drug development and the interdisciplinary cooperation for treating MPS.

ObjectiveTo investigate the prevalence of dental caries among preschool children in Chongming District， Shanghai， and to analyze the related factors influencing dental caries in preschool children in Chongming District， in order to provide references and suggestions for the prevention of dental caries in preschool children in Chongming District. MethodsFrom January to April 2022， 939 preschool children from 5 kindergartens in Chongming District of Shanghai were selected as the research objects through random cluster sampling. The dental caries prevalence rate and related risk factors of dental caries in preschool children were studied through oral examinations and questionnaire surveys. ResultsThe prevalence rate of dental caries among the 939 preschool children was 45.69%. The prevalence of dental caries in preschool children was not related to gender but increased with age （P<0.001）. Risk factors for dental caries in children included consuming desserts between meals or before bedtime （OR=3.049， P<0.001）， consuming sugared milk （OR=2.389， P=0.027）， presence of dental caries in caregivers （OR=1.888， P<0.001）， age （OR=1.758， P<0.001）， regular consumption of certain beverages by children （OR=1.250， P=0.029）， and the frequency of snack consumption （OR=1.191， P=0.034）. ConclusionTo reduce the incidence of dental caries in preschool children， it is recommended that caregivers undergo oral health examinations and dental caries treatment to reduce the transmission of cariogenic bacteria. Additionally， reducing the frequency of children’s consumption of snacks， sugary drinks， and dairy products， and avoiding unhealthy eating habits such as consuming desserts before bedtime are advised. It is also important to educate children on proper toothbrushing methods to ensure the effectiveness of toothbrushing and to encourage them to develop good oral hygiene habits.

Objective:To investigate the post-traumatic growth status of patients with benign central airway stenosis undergoing interventional therapy, and analyze the influencing factors, so as to provide basis for the formulation of measures to improve the treatment tolerance and quality of life of patients.Methods:Patients with benign central airway stenosis treated by interventional therapy in the First Affiliated Hospital of Second Military Medical University from May 2020 to May 2022 were selected by convenient sampling. The general information questionnaire, Chinese Version of Post-traumatic Growth Inventory, Perceived Social Support Scale and Chronic Disease Patients′ Health Literacy Management Scale were used to conduct a cross-sectional survey. Multivariate linear regression was used to analyze the influencing factors of patients′ posttraumatic growth.Results:A total of 183 questionnaires were distributed, and 172 questionnaires were effectively collected, with an effective recovery rate of 93.99% (172/183). The posttraumatic growth score of 172 patients was (62.66 ± 9.54) points; Pearson correlation analysis showed that perceived social support, health literacy and post-traumatic growth were positively correlated ( r=0.483, 0.246, both P<0.05). Multivariate linear regression analysis showed that the degree of stenosis, the number of interventional therapy, social support, and health literacy were the main influencing factors for the post-traumatic growth of patients with benign central airway stenosis undergoing interventional therapy ( t values were -3.46-4.55, all P<0.05), could jointly explain 38.9% of the variation in post-traumatic growth scores. Conclusions:The post-traumatic growth of patients with benign airway stenosis undergoing interventional therapy is at a moderate level. The degree of stenosis and the number of interventional therapy are the limiting factors for post-traumatic growth. Systematic health education, social support and health literacy are conducive to more post-traumatic growth of patients. Medical staff can enhance patients' disease awareness, and provide more channels for acquiring disease knowledge through WeChat groups and WeChat official account, so as to promote patients' post-traumatic growth and reduce their painful experience during treatment.

Medical service price reflects the value and the financial compensation for medical services.The medical service price reform plays an important role in optimizing the allocation of medical resources and transforming the operating mechanism of public hospitals.The pricing of medical services should take many factors into consideration such as the characteristics of medical service,service markets,service costs,supply and demand relationships,medical insurance payment policies,compensation mechanisms,and so on.In response to the current situation of price management methods and price levels for medical service in China,various pricing methods such as cost-based pricing,price-regulation pricing,and demand-oriented pricing should be comprehensively utilized to ex-plore a pricing mechanism that separates medical service value from medical service price,human resource value from material con-sumption value,and build a medical service pricing system that could be coordinated with policy objectives.

ObjectiveTo prepare matrine lipid-based cubic liquid crystalline nanoparticle （MAT-LLCN） gels and investigate its in vitro release and transdermal absorption behavior. MethodTaking entrapment efficiency as the index， the optimal formulation of MAT-LLCN was screened by extreme vertex mixture method based on the optimal ratio of glycerol monooleate （GMO） to poloxamer 407 （P407）， and its drug loading was investigated. MAT-LLCN gels was prepared by mixing MAT-LLCN with pre-swelled carbomer 940 as the gel matrix. The structure of MAT-lipid-based cubic liquid crystalline （LLC） was characterized by polarized light microscopy （PLM） and small angle X-ray scattering （SAXS）. The in vitro release and transdermal absorption properties of MAT-LLCN gels and MAT ordinary gels were compared by modified Franz diffusion cell method， skin structure changes caused by them were observed by hematoxylin-eosin （HE） staining. ResultThe optimal formulation of MAT-LLCN gels was 5.5% of GMO-P407 （9∶1）， 1%-6% of MAT， 0.6% of carbomer 940， adding water to sufficient amount. The prepared MAT-LLC was confirmed as body-centered （Im3m） LLC. The in vitro release behavior of MAT-LLCN gels was in accordance with the Weibull equation （R²=0.954 0）， and the release mechanism was the Fick diffusion. In vitro transdermal test showed that all the parameters of MAT-LLCN gels were higher than those of MAT ordinary gels （P<0.05）， including cumulative release rate， steady-state release rate and the amount of drug retention in skin. HE staining results showed that MAT-LLCN gels could loose the cellular arrangement of skin stratum corneum， and maintain the stability of the cell structure of the dermis. ConclusionThe prepared MAT-LLCN gels can accelerate the transdermal drug transport and form drug storage in the dermis by rapidly opening the skin stratum corneum barrier， suggesting that LLC has good application prospects in the field of transdermal drug delivery.
