ObjectiveTo investigate the effect and mechanism of Yiqi Wenyang Huwei decoction （YWHD） on airway inflammation in bronchial asthma （BA） rats based on transforming growth factor-β₁ （TGF-β₁）/SMAD family member 3 （Smad3） signaling pathway. MethodSixty male SD rats were randomly divided into a normal group， a model group， a dexamethasone （DEX） group， and low-， medium-， and high-dose YWHD groups， with 10 rats in each group. The BA model was induced by intraperitoneal injection of 1 mL of ovalbumin （OVA）-aluminum hydroxide suspension for sensitization， followed by nebulization with 2% OVA. One hour before daily OVA nebulization， the control group was treated with saline， the DEX group with DEX solution at 0.2 g·L^-1， and the low-， medium-， and high-dose YWHD groups with YWHD at 1， 2， 4 g·mL^-1， respectively. General conditions and lung function were observed. Bronchoalveolar lavage fluid （BALF） and serum were collected to count inflammatory cells in BALF and measure immunoglobulin E （IgE） levels in serum and inflammatory cytokines in BALF using enzyme-linked immunosorbent assay （ELISA）. Pathological changes in lung tissues， collagen deposition， and airway mucus secretion were observed by hematoxylin-eosin （HE）， Masson， and periodic acid-Schiff （PAS） staining. TGF-β₁/Smad3-related mRNA and protein levels in lung tissues were determined by Real-time fluorescent quantitative polymerase chain translation （Real-time PCR） and Western blot analysis. ResultCompared with the normal group， the model group showed increased total airway resistance （RL） and decreased dynamic compliance （Cdyn） （P<0.05， P<0.01）， elevated serum IgE levels， increased inflammatory cell counts， and higher inflammatory cytokine levels in BALF （P<0.01）. Additionally， there was significant inflammatory cell infiltration， collagen deposition， and mucus secretion in lung tissues. The levels of TGF-β₁， α-smooth muscle actin （α-SMA）， and Smad3 phosphorylation in lung tissues were significantly increased （P<0.01）. Compared with the model group， the DEX group and high-dose YWHD group exhibited significantly reduced RL （P<0.01）， improved lung dynamic compliance （P<0.05）， and lower serum IgE levels， inflammatory cell counts， and inflammatory cytokine levels in BALF （P<0.05）. Moreover， these treatments alleviated pathological damage in lung tissues and reduced the levels of TGF-β₁， α-SMA， and Smad3 phosphorylation （P<0.01）. ConclusionYWHD reduces airway inflammation， improves pathological damage， and mitigates airway remodeling in bronchial asthma rats， possibly by downregulating TGF-β₁， α-SMA protein levels， and Smad3 phosphorylation.

BACKGROUND:The alteration of miR-146a-3p level is a common event in the pathogenesis of most neurological diseases,and the specific mechanism of miR-146a-3p regulation of astrocytes has not been studied. OBJECTIVE:To verify that miR-146a-3p regulates astrocyte proliferation,migration and apoptosis through insulin-like growth factor 1. METHODS:12 SD rats were divided into a sham operation group and a spinal cord injury group,with six rats in each group.RNA sequencing analysis was performed on the spinal cord tissues of all groups 2 weeks after surgery to screen out the differential genes(log2FC>2),and to select spinal cord injury-related genes(Score>20)in the Genecards database,and then to predict the target genes of miR-146a-3p by Targetscan.The intersection of three gene sets was obtained to screen out insulin-like growth factor 1 as one of the important target genes.qPCR,western blot assay and immunohistochemistry were performed to analyze the expression level of insulin-like growth factor 1 in spinal cord tissues.The primary astrocytes were divided into NC group,NC-mimics group and miR-146a-3p mimics group.Annexin-V/PI staining was used to detect cell apoptosis.CCK-8 assay was used to detect cell proliferation.Transwell assay was used to detect cell migration ability. RESULTS AND CONCLUSION:The expression of miR-146a-3p in the spinal cord tissue of the spinal cord injury group was lower than that of the sham operation group(P<0.05).The expression of insulin-like growth factor 1 in the spinal cord tissue of the spinal cord injury group was higher than that of the sham operation group(P<0.05).Compared with the NC group and NC-mimics group,the apoptotic rate of astrocytes was increased(P<0.01);the proliferation of astrocytes was decreased(P<0.01)and the number of migration was decreased(P<0.01)in the miR-146a-3p mimics group.To conclude,the expression of miR-146a-3p decreased and the expression of insulin-like growth factor 1 increased in spinal cord tissue after spinal cord injury.miR-146a-3p targeted regulation of insulin-like growth factor 1 in astrocytes,inhibited the proliferation and migration of astrocytes and promoted their apoptosis.

Malocclusion,identified by the World Health Organization(WHO)as one of three major oral diseases,profoundly impacts the dental-maxillofacial functions,facial esthetics,and long-term development of～260 million children in China.Beyond its physical manifestations,malocclusion also significantly influences the psycho-social well-being of these children.Timely intervention in malocclusion can foster an environment conducive to dental-maxillofacial development and substantially decrease the incidence of malocclusion or reduce the severity and complexity of malocclusion in the permanent dentition,by mitigating the negative impact of abnormal environmental influences on the growth.Early orthodontic treatment encompasses accurate identification and treatment of dental and maxillofacial morphological and functional abnormalities during various stages of dental-maxillofacial development,ranging from fetal stages to the early permanent dentition phase.From an economic and societal standpoint,the urgency for effective early orthodontic treatments for malocclusions in childhood cannot be overstated,underlining its profound practical and social importance.This consensus paper discusses the characteristics and the detrimental effects of malocclusion in children,emphasizing critical need for early treatment.It elaborates on corresponding core principles and fundamental approaches in early orthodontics,proposing comprehensive guidance for preventive and interceptive orthodontic treatment,serving as a reference for clinicians engaged in early orthodontic treatment.

Background::Antiretroviral therapy (ART) was often associated with dyslipidemia among human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients. This study aimed to assess treatment-na?ve adult male patients with HIV/AIDS who initiated ART with either co-formulated bictegravir, emtricitabine, and tenofovir alafenamide (BIC/FTC/TAF) or lamivudine, efavirenz, and tenofovir disoproxil fumarate (3TC+EFV+TDF), monitoring at weeks 4, 12, 24, and 48.Methods::A case-control retrospective study was conducted. The newly diagnosed HIV-infected individuals attending the sexual transmission disease (STD)/AIDS clinic of Beijing Youan Hospital, Capital Medical University, from January to December 2021. The patients were divided into BIC/FTC/TAF group or 3TC+EFV+TDF group. High-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG), and total cholesterol (TC) at different time points over 48 weeks between two groups were compared. A multivariate Cox regression model was used to identify relevant influencing factors for the population at high risk of increased LDL-C.Results::A total of 870 participants, with 510 in BIC/FTC/TAF group and 360 in 3TC+EFV+TDF group. There were no statistically significant differences in median age, baseline CD4/CD8 ratio, median body mass index (BMI) between the two groups. In both two groups, levels of TG, TC, and LDL-C were higher at 4 weeks, 12 weeks, and 24 weeks of treatment (all P <0.05), and there were no statistically significant differences at 48 weeks compared to those at baseline (all P >0.05). In addition, the differences in average changes of the level of TG, TC, HDL-C, and LDL-C from weeks 4, 12, 24, and 48 to baseline between two groups were not statistically significant (all P >0.05). Multivariate Cox proportional risk model analysis showed that initiating ART with HIV RNA ≥10 5 copies/mL (compared with <10 5 copies/mL) was associated with an increased risk of elevated LDL-C (hazard ratio = 1.26, 95% confidence interval: 1.07-1.48, P = 0.005). Conclusions::Transient elevations in blood lipid levels (TC, TG, HDL-C, and LDL-C) were observed in treatment-na?ve adult male HIV/AIDS patients with BIC/FTC/TAF at 4 weeks, 12 weeks, and 24 weeks of treatment. However, these levels did not differ significantly from baseline after 48 weeks of treatment, regardless of whether patients were in the BIC/FTC/TAF or 3TC+EFV+TDF group.

Objective To observe the impact of semi-solidification enteral nutrition on feeding tolerance,nutritional and infection related indicators,and prognosis in neurocritical patients.Methods Adopting the prospective research method,the neurocritical patients who were admitted to the department of intensive care unit(ICU)of the First Affiliated Hospital of Ningbo University from December 2021 to May 2022 and had to stay in the nasogastric tube for enteral nutrition were selected as the study subjects,pectin was added to achieve the semi-solidification of enteral nutrition,and the patients were divided into pectin group and control group according to the principle of randomized control,with 25 cases in each group.Enteral nutrition was started within 24-48 hours of admission to the ICU in all patients,and pectin plus continuously pumped enteral nutrition preparation was given in the pectin group and continuously pumped enteral nutrition preparation in the control group,all of which was used continuously for more than 7 days.Differences in albumin,prealbumin,Glasgow coma scale(GCS),acute physiology and chronic health evaluation Ⅱ(APACHEⅡ),sequential organ failure assessment(SOFA),procalcitonin(PCT),interleukin-6(IL-6)and C-reactive protein(CRP)were compared between the two groups before and after 7 days of treatment,and enteral nutrition compliance rates at 3 days and 7 days of treatment,as well as the incidence of enteral nutrition intolerance(including vomiting,diarrhea,constipation,aspiration and bloating),along with the length of ICU stay and 28 days prognosis were observed.Results There were no statistically significant differences between the two groups in general clinical data[including gender,age and body mass index(BMI)]and pre-treatment GCS score,APACHEⅡ score,SOFA score,albumin,prealbumin,PCT,IL-6 and CRP levels.The incidence of vomiting,diarrhea,constipation,and bloating during enteral nutrition was significantly lower in the pectin group than those in the control group[vomiting:4.0％(1/25)vs.24.0％(6/25),diarrhea:8.0％(2/25)vs.32.0％(8/25),constipation:20.0％(5/25)vs.65.0％(13/25),bloating:12.0％(3/25)vs.36.0％(9/25),all P<0.05],but the difference in the incidence of aspiration compared with the control group was not statistically significant[4.0％(1/25)vs.16.0％(4/25),P>0.05].Caloric compliance with enteral nutrition was significantly higher in the pectin group than in the control group at both 3 days and 7 days of treatment[3 days of treatment:48.0％(12/25)vs.20.0％(5/25),7 days of treatment:88.0％(22/25)vs.60.0％(15/25),both P<0.05],and the prealbumin level was significantly higher in the pectin group than in the control group at the end of 7 days treatment(mg/L:248.08±43.99 vs.221.64±33.95,P<0.05).There was no statistically significant difference in the comparison of GCS score,APACHEⅡ score,SOFA score,PCT,IL-6,CRP,length of ICU stay,and 28 days mortality between the two groups after treatment.Conclusion The administration of semi-solidification enteral nutrition reduces the incidence of enteral nutrition intolerance,improves caloric intake and nutritional status in neurocritical patients,but has no significant effect on infection indicators and prognosis.

Objective:To investigate the status quo of psychological contracts and influencing factors among members of the "1+N" family doctor teams in Shenzhen and to explore the impact of psychological contracts on job burnout.Methods:This cross-sectional study was conducted from September 30 to October 31, 2022 among 361 members of 92 family doctor teams from 92 community health service centers which provided family doctor team service in Shenzhen city. A self-designed general information questionnaire, an employee psychological contract questionnaire (including organizational responsibility and personal responsibility dimensions), and a job burnout scale (including emotional exhaustion, depersonalization, and personal accomplishment dimensions) were used in the study. T-tests, one-way ANOVA, Pearson correlation analysis, and multiple linear regression analysis were used to analyze the influencing factors of psychological contracts and job burnout.Results:Among 361 respondents, there were 299 females (82.8%) and 62 males (17.2%), and a higher proportion of general practitioners (37.5%, 129/361) and nurses (41.8%, 151/361). The total score of psychological contracts among the 361 respondents was (141.6±19.5), with organizational responsibility scoring (70.6±11.2) and personal responsibility scoring (71.0±9.3). On the job burnout scale, emotional exhaustion scored (17.89±6.82), depersonalization scored (6.51±2.54), and personal accomplishment scored (30.95±5.70). General practitioners scored lower in organizational responsibility and personal responsibility compared to other members ( F=7.341,3.119, all P<0.05), and higher in emotional exhaustion and depersonalization ( F=7.637, 2.415, all P<0.05). Members with≤5 years of work experience scored lower in personal responsibility and personal accomplishment ( F=3.656, 4.205, all P<0.05). Correlation analysis showed that scores of organizational responsibility and personal responsibility were negatively correlated with levels of emotional exhaustion and depersonalization ( r=-0.618, -0.526, all P<0.01), ( r=-0.404, -0.393, all P<0.01), and positively correlated with personal accomplishment ( r=0.500, 0.558, all P<0.01). Multiple linear regression analysis indicated that organizational responsibility negatively affected emotional exhaustion and depersonalization ( β=-0.554, -0.274, all P<0.01), and positively affected personal accomplishment ( β=0.172, P<0.05). Personal responsibility positively affected personal accomplishment ( β=0.404, P<0.01). Conclusions:The study demonstrates that general practitioners in family doctor teams in Shenzhen city have lower psychological contract levels and are more prone to emotional exhaustion and depersonalization; members with≤5 years of work experience have lower personal responsibility and accomplishment. The results indicate that enhancing organizational responsibility can reduce job burnout of members in family doctor teams.

Objective:To survey on the status quo of the role cognition and job burnout among family doctor team members in Shenzhen Futian district.Methods:A survey on the role cognition and job burnout of family doctor members was conducted in October 2022. One family doctor team was randomly selected from each of the 92 community health service centers in Futian district of Shenzhen city, and all members of the selected family doctor teams were included in the survey. The Chinese version of the Maslach Burnout Inventory-Human Services Survey was used in the study, and the influencing factors of role cognition and job burnout, as well as the impact of role cognition on job burnout were analyzed.Results:A total of 361 family doctor team members were included in the survey, The scores of the Role Ambiguity and Role Conflict Scale were (35.25±5.21) and (27.03±13.73), respectively. In the Occupational Burnout Scale, the scores of Emotional Exhaustion, Dehumanization, and Personal Achievement Scale were (17.89±6.82), (6.51±2.54), and (30.95±5.70), respectively. There were significant differences in role ambiguity and job burnout among family doctor team members with different ages, professions, and years of work ( P<0.05). Team members aged≤30, general practitioners, and working time ≤5 years had higher scores for role ambiguity, emotional exhaustion, dehumanization, and lower personal achievement ( P<0.05). The score of role ambiguity was negatively correlated with the degree of emotional exhaustion and dehumanization ( r=-0.544, -0.352), and positively correlated with personal achievement ( r=0.473). The score of role conflict was positively correlated with the degree of emotional exhaustion and dehumanization ( r=0.352, 0.376), and negatively correlated with personal achievement ( r=-0.440). Regression analysis showed that the role cognition was significantly associated with the emotional exhaustion, dehumanization, and personal achievement ( F=10.28-85.12, P<0.01). Conclusion:Active and effective measures should be taken to improve the role cognition and reduce job burnout of family doctor team members in primary health care institutions.

OBJECTIVE To predict the development trends of licensed pharmacist staffing in retail pharmacies within the western China and provide reference for the formulation of policies related to licensed pharmacists. METHODS Based on the data of retail pharmacies and licensed pharmacists in the western China from 2016 to 2022， a grey model was constructed to analyze and predict the number development trends of retail pharmacies and licensed pharmacists in the western China from 2023 to 2026. RESULTS Currently， the 1∶1 staffing requirement for licensed pharmacists and retail pharmacies had been met in Shaanxi， Guangxi and Gansu. Based on current trends， Inner Mongolia， Chongqing， Yunnan， and Qinghai were expected to meet the 1∶1 staffing requirement for licensed pharmacists and retail pharmacies between 2023 and 2026. Sichuan and Xinjiang were also expected to meet this requirement in the future. However， there was still a significant gap in Guizhou， Xizang， and Ningxia towards achieving the above goals. CONCLUSIONS There is still a discrepancy between the deployment of licensed pharmacists and the national requirements in certain western provinces. Local authorities should formulate relevant policies according to local circumstances. Regions that have already met or will soon achieve the staffing requirement for licensed pharmacists should continue to enhance the quantity and quality of their licensed pharmacist workforce. In areas where meet this criterion in the short term is not feasible， it is necessary to strengthen the development of the licensed pharmacist workforce， and control the number of new retail pharmacies.

Objective To identify the potential long non-coding RNA (lncRNA) expressed in rheumatoid arthritis (RA) synovium key to RA onset and investigate its association with immune cell infiltration. Methods RA synovium data were downloaded from the GEO database and normalized. The lncRNAs key to RA onset were identified using multiple machine learning methods. Infiltration of 22 immune cell populations in RA synovium was measured by cell-type identification by estimating relative subsets of RNA transcripts (CIBER-SORT). The relationship between the key lncRNA and infiltrating immune cells was analyzed. Finally, real-time quantitative PCR was applied to validate the expression of the key lncRNA in RA synovial cells. Results lncRNA human leukocyte antigen complex P5(HCP5) was identified as the key lncRNA associated with RA onset. Infiltration analysis revealed increased abundance of CD8⁺ T cells, γδ T cells, and M1 macrophages while decreased abundance of M2 macrophages in RA synovial tissue. Correlation analysis demonstrated that the lncRNA HCP5 expression was positively associated with the infiltration abundance of CD8⁺ T cells, γδ T cells, and M1 macrophages in RA synovial tissue. Furthermore,the expression of lncRNA HCP5 in RA synovial cells was up-regulated. Conclusion lncRNA HCP5 expression is up-regulated in RA synovial tissue and potentially associated with immune cells infiltration.
