This article systematically reviews the current research status as well as diagnosis and treatment strategies of traditional Chinese medicine （TCM） for gastroesophageal reflux disease （GERD）. Studies demonstrate that TCM， based on the "disease-syndrome combination" approach， exhibits multi-target advantages in alleviating symptoms of various GERD subtypes， promoting mucosal repair， regulating emotions， and facilitating the reduction of western medication. To address clinical challenges such as symptom overlap and limited therapeutic efficacy， strategies have been proposed including "treating different diseases with the same method" and integrated regulation based on viscera correlation. Future efforts should focus on elucidating the mechanisms of compound prescriptions， promoting TCM drug development under the "three-combination" evaluation framework that integrates TCM theory， human experience and clinical trial evidence， and optimizing integrated traditional and western medicine models to enhance GERD management.

Objective To explore TCM syndrome distribution law in patients with overlapping non-erosive reflux disease(NERD)and epigastric pain syndrome(EPS)gastrointestinal symptoms.Methods A multi-center,cross-sectional study was conducted to investigate the general information of 800 patients with overlapping NERD and EPS gastrointestinal symptoms in four hospitals,such as gender,age,body mass index(BMI)and four diagnostic information of TCM.Descriptive frequency analysis,factor analysis and clustering analysis were used to summarize the TCM syndrome types and distribution characteristics.Results The average age of 800 patients with overlapping NERD and EPS gastrointestinal symptoms was(44.50±14.43)years old,the average BMI was(23.17±4.80)kg/m2,and the male to female ratio was 3:5.Frequency of 95 TCM symptoms/signs≥20%.18 common factor variables were obtained based on factor analysis,and the cumulative contribution rate was 67.11%.The first three syndrome elements of disease location were liver,stomach and spleen,and the disease nature syndrome elements were qi stagnation,qi deficiency and yin deficiency.Based on the clustering analysis of 18 common factor variables,combined with expert discussion,four main TCM syndrome types were obtained,which were liver-stomach stagnation heat syndrome(213 cases,26.63%),spleen-stomach damp heat syndrome(209 cases,26.13%),spleen-stomach deficiency and cold qi stagnation syndrome(190 cases,23.75%)and qi-phlegm stagnation syndrome(188 cases,23.50%).There was no significant difference in the distribution of TCM syndrome types among patients with different genders,ages and BMI values(P>0.05).Patients with a course of disease≥2 years and those residing long-term north of the Qinling-Huaihe Line showed a significantly higher prevalence of spleen-stomach dampness-heat syndrome(P<0.05).Conclusion The syndrome elements of disease location of overlapping NERD and EPS gastrointestinal symptoms are mainly liver,stomach and spleen.The TCM syndrome types are liver-stomach stagnation heat syndrome,spleen-stomach damp heat syndrome,spleen-stomach deficiency cold qi stagnation syndrome and qi-phlegm stagnation syndrome.The course of disease and the regional differences between north and south may be the influencing factors of the distribution of syndrome types.

OBJECTIVE To understand the disinfectant-resistant genes in the gram-negative bacteria isolated from the dirt retention on air recure filters of air conditioners and observe the drug resistance.METHODS The dirt re-tention samples were collected from the air return filters of air conditioners of some wards in 3 hospitals of Wuhan(Tongji Hospital of Tongji Medical College of Huazhong University of Science and Technology,Wuhan Central Hospital,and Hubei Provincial Maternal and Child Health Hospital)from 2018 to 2024.The gram-negative bac-teria were screened out,the disinfectant-resistant genes in the strains were detected by polymerase chain reaction(PCR),and the results of drug susceptibility test were analyzed.RESULTS Of 354 dirt retention samples that were collected from the air return filers of air conditioners,77 were detected with 138 strains of gram-negative bacteria,87 of which were Acinetobacter baumannii,50 were Enterobacteriaceae,and 1 was Pseudomonas aerug-inosa.The detection rates of qacEΔ1,qacEΔ1-sul1,aceI and qacA/B were 73.19％,82.61％,69.57％and 2.90％,respectively.None of the strains were detected with qacC,qacH or qacJ.The result of drug susceptibility test showed that 76.81％of the gram-negative bacteria were resistant to at least 1 type of antibiotic;93 strains of multidrug-resistant gram-negative bacteria were isolated,most of which were isolated from intensive care unit(ICU).The detection rates of qacEΔ1 and qacEΔ1-sul1 were higher in the drug-resistant strains than those in the non-drug-resistant strains;there were significant differences in the drug resistance rates to carbapenems,quin-olones and β-lactams between the qacEΔ1-sul 1-positive strains and the qacEΔ1-sul1-negative strains(P＜0.05).CONCLUSIONS There are drug-resistant gram-negative bacteria contaminations in some wards of the 3 hospitals in Wuhan.The carrying rates of disinfectant-resistant genes of the strains are high,and the strains show varying degree of resistance to the commonly used antibiotics;the strains carrying the qacEΔ1-sul1 have certain statistical association with the drug resistance.It is suggested that the hospital should take targeted disinfec-tion measures for the environment and reasonably use antibiotics.

Leukocyte differentiation antigen CD109(CD109)is a glycosylphosphatidylinositol(GPI)-associated cell surface antigen,belonging to the α-2 macroglobulin/C3,C4 and C5 super family complex,and is a transfor-ming growth factor(TGF)-β/Smads co-receptor.CD109 regulates the occurrence and development of glioma and is closely related to drug resistance and recurrence of glioma.As a cell membrane protein,CD109 can be directly la-beled by specific antibodies or enzymes,and may also be recognized by targeted vectors for drug delivery,which is expected to become an effective diagnostic molecular marker and pharmacological therapeutic target.

Objective:Taking naval officers and soldiers who participate in military continuing education as an example, to compare the distribution of sensory learning style of learners with different personality in order to provide suggestions and references for online course teaching.Methods:By using convenient sampling method, MBTI (Myers-Briggs Type Indicator) and VARK (Visual, Aural, Read/Write, Kinesthetic questionnaire) were measured in the Navy. A total of 10 000 questionnaires were distributed and 8 124 valid ones were collected. Through analysis of SPSS 25.0 software, the personality dimensions and personality types were analyzed for personality analysis, and the main indicators of sensory learning style analysis were tendency multiplicity, the intensity and distribution of single sensory learning style, and specific sensory learning styles. The Chi-square test was adopted, with test level of α=0.05. Results:It showed statistical differences in the tendency multiplicity and intensity of single style among officers and soldiers in the three dimensions of extroversion-introversion, sensing-intuition and judging-perception ( χ 2=12.37, 18.02, 22.97, 12.57, 12.73, 24.45, P=0.005, <0.001, <0.001, =0.006, =0.005, <0.001). It showed statistical differences in the distribution of single style and the specific sensory learning styles among officers and soldiers in all the four dimensions of extroversion-introversion, sensing-intuition, thinking-feeling, and judging-perception ( χ 2=28.30, 36.96, 11.40, 41.95, 53.76, 75.48, 43.11, 77.29, P <0.001, <0.001, =0.022, <0.001, <0.001, <0.001, <0.001, <0.001). It showed statistical differences in the tendency multiplicity, the intensity and distribution of single style, and the specific sensory learning styles among naval officers and soldiers with different personality types ( χ 2=86.63, 96.22, 147.41, 363.76, all P<0.001). Conclusions:Personality dimension has influence on sensory learning style, especially for extroversion-introversion, sensing-intuition, and judging-perception dimensions. Personality type has an important influence on the tendency multiplicity, distribution type and performance intensity of sensory learning style. It is integral part of online course teaching to meet the diversified and personalized learning needs of officers and soldiers.

Objective:To investigate the association between exposures of seven classic phthalate metabolites and fertility among preconception women before pregnancy.Methods:Based on the preconception cohort, a nested case-control study was carried out. Preconception couples who were recruited from Shanghai Jiading District Maternal and Child Health Hospital from 2016 to 2020 with intention to conception were selected. A total of 100 women whose time to pregnancy (TTP) >12 months were selected as the case group, and 151 women with the TTP≤12 months were randomly selected as control group. The single and joint effects on fertility of phthalate metabolites were analyzed by the comparison between the two groups via the multivariate binary logistic regression model, and the weighted quantile sum regression model.Results:There were significant differences in mono-(2-ethylhexyl) phthalate (MEHP), mono-(2-carboxmethyl)-hexyl phthalate (MCMHP), the sum of the detected concentrations of MEHP, MCMHP, mono-(2-ethyl-5-oxohexyl) phthalate, mono-(2-ethyl-5-hydroxyhexyl) phthalate and mono-(2-ethyl-5-carboxypentyl) phthalate (∑DEHP), and the sum of the detected concentrations of the seven phthalate metabolites (∑PAE) exposure levels between the case group and control group ( P=0.005, P<0.001, P=0.001, P=0.007). As shown by the multivariate binary logistic regression model, women with MEHP, MCMHP, ∑DEHP, ∑PAE at the highest quartile level were found to have significantly increased risk of infertility compared with women at the lowest quartile level (a OR=2.40, 95% CI: 1.12-5.15, P=0.025; a OR=7.74, 95% CI: 3.14-19.08, P<0.001; a OR=4.35, 95% CI: 1.93-9.79, P<0.001; a OR=2.04, 95% CI: 0.96-4.34, P=0.044). The weighted quantile sum regression model demonstrated that the exposure to seven phthalate metabolite mixtures in preconception was associated with an increased risk of infertility ( P<0.05). Among the seven phthalate metabolites, MCMHP had the largest contribution weight (61.7%). Conclusion:Women of childbearing age should avoid the exposure to phthalates in the environment when preparing for conception, such as to reduce the consumption of highly processed foods and foods packaged with plastic/polyvinyl chloride materials to promote fertility.

Objective: This study aimed to evaluate the validity and predictive value of different methods for myopia screening, and to provide the most effective method of myopia screening. Methods: A total of 7 441 students of grade 1-12 selected from 36 primary and middle schools in 12 counties in Jiangsu Province were enrolled in this study for ophthalmological examination, and uncorrected visual acuity (UCVA, Plan A), noncycloplegic autorefraction (NCAR, Plan B) and combination of UCVA and NCAR (Plan C) were included in the examination. Receiver operating characteristics (ROC) curve was performed to determine the cut-off values (The gold standard is cycloplegic refraction: SE≤0.5 D), and positive predictive value, sensitivities, specificities and other indicators of three screening tests were compared and calculated. Results: The AUC of the combination test for uncorrected visual acuity(UCVA) and noncycloplegic autorefraction (NCAR) was nearly 1(0.91, 95%CI=0.90-0.92), and the sensitivity, specificity, Yoden index, diagnostic coincidence rate, positive predictive value and negative predictive value were 92.4%，89.5%，0.82，91.1%，91.3%，90.8%, respectively, but the index of the younger pupils in primary schools was relatively low. The result of screening plan A for students of middle and high school students was the closest to that of myopia diagnosis. Conclusion Combination test, which was recommended by China National Health Commission, can be a practical solution for school students for myopic screening. Under the condition of no mydriatic refraction, Plan A could be considered for myopia screening especially for middle and high school students. For the younger pupils, it is suggested to use the internationally recommended myopia screening strategy, that is, SE ≤ 0.50D after mydriasis.
