Sangjuyin， as a pungent and cooling agent with precise therapeutic effect， is a classic pungent formula for cooling relief of the epidermis， which is highly respected by medical practitioners. This formula is from the Wenbing Tiaobian written by WU Jutong in the Qing dynasty， on the basis of which subsequent medical practitioners have made additions and subtractions to apply it. The authors used the bibliometric method to systematically organize the medical books from the Qing dynasty and the Republic of China and modern literature to analyze the composition， concoction， decoction， efficacy， and previous and modern application of Sangjuyin. After examination， the drug base of this formula is basically clear. Armeniacae Semen Amarum is the dried mature seeds of Armeniaca vulgaris， family Rosaceae. Forsythiae Fructus is the dried fruit of Forsythia suspensa， family Mulleinaceae. Menthae Haplocalycis Herba is the dried above-ground part of Mentha haplocalyx， family Labiatae. Mori Folium is the dried leaves of Morus alba， family Moraceae. Chrysanthemi Flos is the dried head of Chrysanthemum morifolium， family Asteraceae. Platycodonis Radix is the dried root of Eryngium grandiflorum， family Eryngium. Glycyrrhizae Radix et Rhizoma is the dried root and rhizome of Glycyrrhiza uralensis of the Leguminosae family， and Phragmitis Rhizoma is the fresh or dried rhizome of Phragmites communis of the Gramineae family. It is recommended that the eight drugs be used in raw form as medicine. The dosage and method of decoction were converted into a modern single dosage of 7.46 g Armeniacae Semen Amarum， 5.60 g Forsythiae Fructus， 2.98 g Menthae Haplocalycis Herba， 9.33 g Mori Folium， 3.73 g Chrysanthemi Flos， 7.46 g Platycodonis Radix， 2.98 g Glycyrrhizae Radix et Rhizoma， and 11.19 g Phragmitis Rhizoma， with 400 mL water added， and the solution was boiled to obtain 200 mL， taken twice a day. Sangjuyin has the efficacy of dispersing wind and clearing heat， promoting lung and relieving cough， and it is used for treating the initial onset of wind-warmth and the evidence of evil spirits in the lungs and collaterals. Modern research has shown that Sangjuyin is often used in the treatment of cough， pneumonia， rhinitis， and other respiratory diseases， and the results of this study provide a reference for the later development of Sangjuyin.

Background Health literacy is closely related to mental health, and improving health literacy has been shown to promote mental well-being. However, whether occupational stress among workers in mining and manufacturing is associated with their occupational health literacy remains inconclusive. Objective To study the levels of occupational health literacy and occupational stress among workers in three industrial sectors (metal ores mining, metal smelting, and manufacture of non-metallic mineral products) in Gansu Province, and to analyze the correlation between them. Methods Between May and December 2024, a stratified cluster random sampling method was employed to survey workers from 73 large, medium, and small and micro sized enterprises across the aforementioned industries in Gansu Province. Participants’ occupational health literacy and occupational stress levels were assessed. The LASSO regression model was applied to identifykey factors influencing occupational stress, and subsequently a multilevel random intercept mixed-effects logistic model was used to study factors influencing occupational stress and to explore the relationship between occupational health literacy and occupational stress. Results A total of 3611 workers across the three industries were surveyed, among whom 1031 (28.55%) experienced occupational stress. Workers with adequate occupational health literacy—whether assessed in terms of overall literacy or specific dimensions—demonstrated a significantly lower prevalence of occupational stress compared to those without adequate literacy (P<0.05). Through the LASSO regression analysis, it was found that the factors closely related to occupational stress were dimension one (occupational health legal knowledge), dimension two (basic knowledge of occupational health protection), and dimension four (healthy working methods and behaviors) of occupational health literacy, gender, average monthly income, and night shifts. The results from the three-level random intercept mixed-effects logistic regression model indicated that dimensions one (OR=0.69, 95%CI: 0.58, 0.82), two (OR=0.71, 95%CI: 0.58, 0.87), and four (OR=0.81, 95%CI: 0.67, 0.98) of occupational health literacy were negatively correlated with the risk of occupational stress. Workers with an average monthly income of 3001–≤5000, 5001–≤7000, and ≥7001 yuan reported occupational stress risks that were 61% (OR=0.61, 95%CI: 0.45, 0.81), 56% (OR=0.56, 95%CI: 0.41, 0.78), and 36% (OR=0.36, 95%CI: 0.24, 0.53) of those with an average monthly income ≤3000 yuan, respectively. Male workers (OR=1.66, 95%CI: 1.32, 2.10) and those on night shifts (OR=2.29, 95%CI: 1.90, 2.76) had a higher risk of occupational stress. The random effects variance showed that the intraclass correlation coefficient was 0.12. Conclusion There is a negative correlation between occupational stress and occupational health literacy among workers in mining and manufacturing. Being male, having a low income, and working night shifts are risk factors affecting workers' occupational stress. It is recommended to focus on these groups of workers and incorporate occupational health literacy into workplace mental health promotion.

Objective: To assess the association of family food environment with dietary and nutrition literacy among junior and senior high school students, providing a basis for nutritional health education and adolescent nutritional improvement. Methods: From January 9 to February 10, 2025, a total of 1 473 junior and senior high school students aged 12-20 were recruited by using a cluster random sampling method combined with convenient sampling from 15 provinces (municipalities and autonomous regions) across China. Data on basic demographic characteristics, home food environment, and dietary and nutrition literacy were collected by using the Food and Nutritional Literacy Questionnaire for Chinese School age Children. Multiple linear regression and Logistic regression models were employed to analyze the association of the home food environment on adolescent dietary and nutrition literacy. Results: The total score of dietary and nutrition literacy among junior and senior high school students was (65.28±9.03). The score in the cognitive domain (67.59±10.56) was higher than that in the skill domain (60.74±9.15), and the score for food preparation skills (56.60±14.28) was the lowest. Students aged 16-20, senior high school students, those for only children, non boarding students, those with urban household registration, those from wealthier families, those whose primary caregivers were parents with higher education levels, and those who previously received nutrition and health education had significantly higher dietary and nutrition literacy scores compared to their respective counterpart groups ( t/F =-8.32, -8.14, 4.76, -2.70, 7.15, 18.29, 10.68, 11.66 , all P <0.05). Multiple linear regression analysis revealed that family food environment was associated with dietary and nutrition literacy, and the model was statistically significant ( R 2=0.20, F=20.54, P <0.05). Lower availability of fruits at home in the past month and lower frequency of family communication regarding dietary and nutrition were associated with lower dietary nutrition literacy scores among junior and senior high school students ( β =-1.35, -1.67, both P <0.01). Among junior and senior high school students, lower frequency of dining out with the family, watching videos during family meals, and being urged by parents to eat more food in the past month were associated with higher scores on dietary nutrition literacy ( β =1.35, 1.13, 0.71, all P <0.01). Logistic regression model results indicated that watching videos during family meals ( OR =1.70) and family communication regarding dietary and nutrition ( OR =0.51) were significantly associated with dietary and nutrition literacy levels (both P <0.05). Conclusions The score of dietary and nutrition literacy among junior and senior high school students is relatively low, and the family food environment is a key factor. It is recommended that nutrition education and improvement initiatives for junior and senior high school students prioritize attention on children and adolescents from households with less favorable food environments.

AIM:To study the effect of Sanhuang Gel on the expression of TLRs/NLRP3 signal path-way in auricle acne model rats,and to explore its mechanism in treating acne inflammatory injury.METHODS:A rat model of auricular acne was in-duced by applying 100％oleic acid to the opening of the right ear catheter and injecting Propionibac-terium acnes.Rats were divided into normal group,model group,positive control group(clindamycin hydrochloride gel 10 mg/g)and Sanhuang Gel high,medium and low dose groups(280,140 and 70 mg/g).Each drug group was given drug intervention for 28 days.The changes of auricle skin lesions in each group were observed;Hematoxylin-eosin(HE)staining was used to observe the pathological changes of auricle acne.The ultrastructural chang-es of auricle tissue cells were observed by transmis-sion electron microscope(TEM).The distribution and expression changes of TLR2 and TLR4 in rat au-ricle tissue were detected by immunofluorescence.The expressions of TLR2,TLR4,NLRP3,ASC and Cas-pase-1 mRNA in rat auricle were detected by Real-time PCR.The expressions of TLR2,TLR4,NLRP3,ASC and Caspase-1 in rat auricle were detected by Western blot.RESULTS:Compared with the normal group,papules,pustules,inflammatory cell infiltra-tion and obvious edema of mitochondria can be seen in the auricle tissue of the model group.The mRNA and protein expression levels of TLR2,TLR4,NLRP3,ASC andCaspase-1 increased significantly(P＜0.01).Compared with the model group,the ap-pearance and pathological damage of auricle in each treatment group were obviously alleviated,and the morphology and structure of mitochondria returned to normal.The mRNA expression levels of TLR2,TLR4,NLRP3,ASC and Caspase-1 decreased significantly(P＜0.01).The expression levels of TLR2,TLR4,NLRP3,ASC and Caspase-1 in positive control group and high and middle dose groups de-creased(P＜0.01,P＜0.05).The expression levels of ASC and Caspase-1 protein in low dose group were significantly decreased(P＜0.01),but there was no significant difference in the expression levels of TLR2,TLR4 and NLRP3 protein(P＞0.05).CONCLU-SION:Sanhuang Gel can improve the pathological damage of auricle tissue and reduce immune in-flammatory reaction in acne rats,and its mecha-nism may be related to regulating TLRs/NLRP3 sig-naling pathway.

Objective:To investigate gut microbiota differences between individuals with and without colorectal adenoma(CRA)and to identify gut microbes associated with CRA.Methods:This cross-sectional study analyzed the gut microbiota of 100 patients with CRA and 68 individuals without CRA(aged 40-75 years)who underwent colonoscopies between March 2021 and March 2022 at Tianjin Nankai Hospital.Fecal samples were sequenced for the V3-V4 region of the bacterial 16S rRNA gene using the Illumina NovaSeq platform.Results:Compared to the non-CRA group,the CRA group exhibited reduced relative abundances of identified and unidentified Lachnospiraceae,with increased Faecalibacterium and Streptococcus.In the non-CRA group,the relative abundances of Coprococcus,unidentified Clostridiaceae,and Clostridium were higher.LEfSe analysis revealed significant enrichment of Gammaproteobacteria,Proteobacteria,Enterobacteriales,and Faecalibacterium in the CRA group,while the non-CRA group was enriched for Moraxellaceae,Acinetobacter,and Anaerostipes.Conclusions:These findings suggest a discernible disparity in the gut microbiota structure between CRA patients and individuals without adenoma.The enrichment of potential pathogenic taxa,such as Faecalibacterium and Streptococcus,in the CRA group suggests a possible association with adenoma development.

Objective:To investigate the molecular mechanisms by which HMGB1 in lung cancer cells affects the function of lung cancer cells themselves and immune cells through the NF-κB pathway.Methods:Western blot detected HMGB1 expressions in Lewis lung cancer(LLC)cells,Raw264.7 cells,and mouse spleen cells,while tumor cell lysates(TCL)with low HMGB1 was pre-pared by inhibiting HMGB1 expression in lung cancer cells with glycyrrhetinic acid(GA);the effects of endogenous HMGB1 inhibi-tion or TCL with low HMGB1 on apoptosis and proliferation of lung cancer cells were detected by flow cytometry and CCK-8;TCL with normal HMGB1 or TCL with low HMGB1 was prepared by freeze-thawing;Raw264.7 cells and mouse splenocytes were treated with them for 48 h.Apoptosis and CD69 expression were detected by flow cytometry,and secretion of cytokines IL-2,IL-4,IL-6,TNF-α and TNF-β were detected by ELISA;Western blot detected lung cancer cells or immune cells.Western blot was performed to detect the protein expression of key signaling molecules of the NF-κB signaling pathway in lung cancer cells or immune cells.Results:HMGB1 was expressed in LLC cells,Raw264.7 cells,and mouse spleen cells,among which LLC cells had the highest expression of HMGB1,and 30 μg/ml GA had the best inhibitory effect on HMGB1 expression in LLC cells.Endogenous HMGB1 in LLC cells could promote cell proliferation.Exogenous HMGB1 in TCL induced apoptosis in lung cancer cells and inhibited immune cell activation and prolifera-tion.Inhibition of endogenous HMGB1 in lung cancer cells leaded to activation of the apoptosis-inducing factor CASP9 in the NF-κB signaling pathway,which was inhibited in lung cancer cells or immune cells after the action of TCL with low HMGB1.Conclusion:Tumor cell HMGB1 has a dual role in lung carcinogenesis,promoting the proliferation of lung cancer cells while suppressing the func-tion of immune cells,which in turn causes lung carcinogenesis,a process associated with the activation of the NF-κB signaling path-way in different cells.

Objective To compare the difference,agreement,and axial length measurement success rate between biometers ZW-30 and IOLMaser 700 based on swept-source optical coherence tomography for the measurement of ocular bi-ological parameters in patients with cataracts.Methods A total of 126 cataract patients(233 eyes)who were advised to undergo cataract surgery at the Department of Ophthalmology at Beijing Tongren Hospital,Capital Medical University from January to February 2024 were included in this study.Two biometers were used to measure the axial length(AL),mean keratometry(Km),anterior chamber depth(ACD),lens thickness(LT),central corneal thickness(CCT),and horizontal corneal diameter[namely,the white-to-white(WTW)distance].The axial measurement success rate of the two biometers and the difference and agreement between the parameters were calculated.Results The mean difference between ZW-30 and IOLMaster 700 was(-0.006±0.042)mm for AL,(-0.074±0.204)D for Km,(0.031±0.051)mm for ACD,(0.001±0.005)mm for CCT,and(-0.286±0.337)mm for WTW,and the differences were statistically significant(all P＜0.05).The mean difference between ZW-30 and IOLMaster 700 was(0.008±0.215)mm for LT,and the difference was not statis-tically significant(t=0.579,P=0.563).The 95％limits of agreement range was between-0.011 mm and 0.000 mm for AL,between-0.474 D and 0.326 D for Km,between-0.010 mm and 0.012 mm for CCT,between-0.068 mm and 0.131 mm for ACD,between-0.116 mm and 0.159 mm for LT,and between-0.947 mm and 0.376 mm for WTW.The intra-class correlation coefficient of all measurements ranged from 0.790 to 1.000.The AL measurement success rate of IOLMaster 700 and ZW-30 was 95.3％and 95.7％,respectively.The latter had an AL measurement success rate of 98.7％after manually marking the position of the retinal identification line.Conclusion There were statistically significant differences between ZW-30 and IOLMaster 700 in the measurement of the AL,Km,ACD,and CCT,which,however,were not clinically significant.The agreement between both was good.ZW-30 had a higher AL measurement success rate,espe-cially for the manual identification function of eyes with opacified refractive media,which can further improve the AL meas-urement success rate and provide reference for clinical work.
