Secondary organizing pneumonia after infection is a pathological condition characterized by connective tissue filling and obstructing the alveoli and bronchioles, in which following an infection in the lung, the inflammatory response is not controlled in a timely and effective manner. The pathogenesis and treatment of this condition can be interpreted through the Sanjiao membranous tube theory and the concept of stagnation within the pulmonary micro-membrane. Sanjiao is conceptualized as a four-way membranous tube that internally connects with the zangfu organs and externally with the skin and muscles, enabling the circulation of energy and fluids throughout the body. It also maintains communication with the zangfu micro-membranes. Within the lungs, the pulmonary micro-membrane is distributed and connected to the upper jiao membranous tube, facilitating the movement of qi and fluids and supporting nutrient distribution. External pathogens may invade the Sanjiao membranous system through the external membranous tube, travel internally along this system, and transform into latent pathogens that settle within the pulmonary micro-membrane. These latent pathogens can subsequently transform into heat or dampness, leading to the depletion of lung qi and impairing the lung′s ability to regulate and transport body fluids. Consequently, fluids may seep into the pulmonary micro-membrane, where they are transformed into dampness, turbidity, and phlegm. The accumulation of damp-turbidity and phlegm obstructs the flow of qi and blood, resulting in blood stasis in the pulmonary collaterals. This stagnation occurring within both the pulmonary micro-membrane and its associated collaterals underlies the development of secondary organizing pneumonia after infection. In severe cases, this condition may progress to pulmonary interstitial fibrosis. The therapeutic approach emphasizes expelling latent pathogens, regulating and dredging the pulmonary micro-membrane, tonifying the healthy qi, and supporting health. Regulating and dredging the pulmonary micro-membrane is a crucial step, with a focus on promoting the flow of lung qi, resolving dampness and phlegm, and activating blood circulation to remove stasis.

In recent years， the incidence of pulmonary nodules has kept rising. To give full play to the advantages of traditional Chinese medicine （TCM） in the treatment of pulmonary nodules and identify the breakthrough points of integrating TCM with Western medicine， the China Association of Chinese Medicine organized medical experts in TCM and western medicine to carry out in-depth discussion regarding this disease. The discussion encompassed the modern medical advances， TCM theories of etiology and pathogenesis， the role and advantages of TCM in the whole course management of pulmonary nodules， contents and methods of research on pulmonary nodules， and science popularization work， aiming to provide a reference for clinical practice and scientific research. After discussion， the experts concluded that the occurrence of pulmonary nodules was rooted in the deficiency of the lung and spleen and triggered by phlegm dampness， blood stasis， and Qi stagnation. TCM can treat pulmonary nodules by controlling and reducing nodules， improving physical constitution， ameliorating multi-system nodular diseases， reducing anxiety and avoiding excessive diagnosis and treatment， and serving as an alternative for patients who are unwilling or unfit for surgical treatment. At present， the optimal diagnosis and treatment strategy for pulmonary nodules has not been formed， which needs to be further studied from multiple perspectives such as clinical epidemiology， biology， and evidence-based medicine. The primary task of current research is to find out the advantages， effective prescriptions， and target populations and determine the effective outcomes of TCM in the treatment of pulmonary nodules. At the same time， basic research should be carried out to explore the etiology and biological behaviors of pulmonary nodules. The expert consensus on the diagnosis and treatment of pulmonary nodules with integrated TCM and Western medicine needs to be continuously revised to guide clinicians to conduct standardized， scientific， and accurate effective diagnosis and treatment.

Objective To analyze the effects of down-regulation+hormone replacement therapy(HRT)endometrial preparation regimen on the pregnancy outcomes of advanced age women(≥35 years old)undergoing frozen-thawed embryo transfer.Methods The clinical data of 329 patients with frozen-thawed em-bryo transfer in this hospital from June 2020 to June 2022 were analyzed retrospectively.Among them,149 pa-tients receiving gonadotropin-releasing hormone analogue(GnRHa)down-regulation+HRT endometrial preparation were included in the group A,and the other 180 patients with HRT endometrial preparation were included in the group B.The basic situation,endometrial transformation day situation and clinical outcome were compared between the two groups.The group A and group B were further divided into the two sub-groups according to age:group A1(35-＜40 years old,n=101),group A2(≥40 years old,n=48),group B1(35-＜40 years old,n=99)and group B2(≥40 years old,n=81).The effects of two endometrial prepara-tion regimens were compared among the different age groups.Results There were no significant differences in the age,infertility years,BMI,anti-Mullerian hormone level,as well as basal hormones levels such as estra-diol,progesterone,follicle-stimulating hormone,luteinizing hormone(LH),prolactin and testosterone between the two groups(P＞0.05).The levels of estradiol and LH on the endometrial transformation day in the group A were significantly lower than those in the group B(P＜0.05),the endometrial thickness,proportion of the patients with endometrial thickness ≥8 mm and proportion of the patients with type Ⅲ blood intima in the group A were significantly higher than those in the group B(P＜0.05).There was no significant difference in the number of transplanted embryos and the number of transplanted excellent embryos between the two groups(P＞0.05).The clinical pregnancy rate and embryo implantation rate in the group A were significantly higher than those in the group B(46.31％vs.35.56％;33.33％vs.25.18％,P＜0.05),and there was no significant difference in the early miscarriage rate between the two groups(P＞0.05).The further subgroup analysis showed that the clinical pregnancy rate and embryoimplantation rate in the group A2 were significant-ly higher than those in the group B2(35.42％vs.18.52％;21.43％vs.12.40％,P＜0.05),while there was no significant difference between the group A1 and group B1(P＞0.05).Conclusion The advanced age pa-tients undergoing frozen-thawed embryo transfer could select GnRHa down-regulation+HRT regimen to a-chieve better pregnancy outcomes,especially for those age ≥40 years old.

Objective To investigate the relationship between the central foveal thickness(CFT),ellipsoid zone(EZ)interruption ratio and best corrected visual acuity(BCVA)in patients with idiopathic epiretinal membranes(iERM).Methods A retrospective case-control study was conducted.The cluster sampling method was used to select 336 iERM patients(500 eyes)who underwent physical examinations in 9 community hospitals of the Kailuan Group from 2014 to 2018.Among them,215 were male(64.0％)and 121 were female(36.0％),with an average age of 31-89(66.4±8.8)years.According to the gass classification,these patients were divided into three groups:gass 0 group(201 patients,305 eyes),gass 1 group(75 patients,101 eyes),and gass 2 group(60 patients,94 eyes).Pearson correlation analysis was used to evaluate the correlation between BCVA(converted to logMAR visual acuity)and gass classification,EZ interruption ratio,CFT.Results The average BCVA(logMAR)and CFT of 500 eyes were 0.45±0.28 and(337.6±101.8)μm,re-spectively,with EZ interruption in 86 eyes(17.2％).There were statistically significant differences in BCVA(logMAR)(0.62±0.29,0.48±0.23,0.26±0.32),CFT[(283.20±79.30)μm,(335.50±84.50)μm,(394.00±135.60)μm],and EZ interruption ratio(2.6％,20.8％,60.6％)among gass 0,gass 1 and gass 2 groups(all P＜0.05).Pearson correlation analysis showed that there was no correlation between age and BCVA among different groups(r2=0.021,P=0.314);BCVA was positively correlated with CFT(r2=0.531,P=0.000),EZ interruption ratio(r2=0.304,P=0.000),and gass classification(r2=0.587,P=0.000).Conclusion The EZ interruption may occur in the early stage of iERM.BCVA is correlated with CFT,EZ interruption ratio and gass classification;the incidence of EZ interruption in gass 2 iERM signifi-cantly increases.

Objective To investigate the relationship of miRNA gene polymorphisms with blood pressure(BP)responses to the sodium and potassium diet intervention.Methods In 2004,we recruited 514 participants from 124 families in seven villages of Baoji,Shaanxi Province,China.All subjects were given a three-day normal diet,followed by a seven-day low-salt diet,a seven-day high-salt diet,and finally a seven-day high-salt and potassium supplementation.A total of 19 miRNA single nucleotide polymorphisms(SNPs)were selected for analysis.Results Throughout the sodium-potassium dietary intervention,the BP of the subjects fluctuated across all phases,showing a decrease during the low-salt period and an increase during the high-salt period,followed by a reduction in BP subsequent to potassium supplementation during the high-salt diet.MiR-210-3p SNP rs 12364149 was significantly associated with systolic BP(SBP),diastolic BP(DBP)and mean arterial pressure(MAP)responses to low-salt diet.MiR-4638-3p SNP rs6601178 was significantly associated with SBP while miR-26b-3p SNP rs115254818 was significantly associated with MAP responses to low-salt intervention.In addition,miR-26b-3p SNP rs115254818 was significantly correlated with SBP,DBP and MAP responses to high-salt intervention.MiR-1307-5p SNPs rs1 1191676 and rs2292807 were associated with SBP and MAP responses to high-salt diet.MiR-4638-3p SNP rs6601178,miR-210-3p SNP rs12364149,miR-382-5p SNP rs4906032 and rs4143957 were significantly associated with SBP response to high-salt diet.In addition,miR-26b-3p SNP rs115254818 was significantly associated with SBP,DBP and MAP responses to potassium supplementation.MiR-1307-5p SNPs rs11191676,rs2292807,and miR-19a-3p SNP rs4284505 were significantly associated with SBP responses to high-salt and potassium supplementation.Conclusion miRNA gene polymorphisms are associated with BP response to sodium and potassium,suggesting that miRNA genes may be involved in the pathophysiological process of salt sensitivity and potassium sensitivity.

To explore screening tools for children with autism spectrum disorder (ASD), which are convenient for primary hospitals, it can provide basic data for formulating ASD prevention policies. This was a cross-sectional study by cluster sampling. Huyi District and Xincheng District were extracted for investigation in Xi′an City. From July 2021 to September 2022, all children aged from 3 months to 36 months who live in the two districts were subjected to primary screening. The child care physician used the routine screening tool "warning signs checklist for screening psychological, behavioral and developmental problems of children" and cartoon pictures of "early high-risk warning signs of autism", the children who were positive in the initial screening were referred to the district level maternal and child health hospital for re-screening, and those who were positive in the re-screening were referred to Xi ′an Children′s Hospital for diagnosis. The results showed that a total of 17 905 children aged from 3 months to 36 months were initially screened in the two districts, including 10 588 children aged from 18 months to 36 months, 50 children who were positive in the initial screening and 50 children who were re-screened. 23 children (18 boys and 5 girls) were diagnosed with ASD. The prevalence rate of ASD in children was 2.17‰ (95% confidence interval:1.29‰-3.06‰). 42 children were positive for "warning signs checklist" at the preliminary screening, and 19 were confirmed as ASD. 27 children were positive for "cartoon pictures" in the preliminary screening, and 23 were confirmed with ASD. The "cartoon pictures" in the preliminary screening and diagnosis of consistent rate was higher than the "warning signs checklist", two kinds of screening methods comparison were statistically significant difference in the odds of consistent (χ 2=11.01, P=0.001). In conclusion, relying on the three-level network of maternal and child health care, it is conducive to the whole process management of screening and diagnosis of children with ASD, and to guide the formulation of prevention policies. The cartoon pictures of "early high-risk warning signs of autism" can assist the identification of children with ASD based on the "warning signs checklist", which is simple, effective and suitable for promotion in the community health care.

Objective:To determine the diagnostic accuracy and prognosis of fetal congenital heart disease (CHD) detected by ultrasound at 11-13 weeks gestation.Methods:Fetuses at 11 to 13 + 6 weeks gestation in the Maternal and Child Health Hospital of Guangxi Zhuang Autonomous Region between January 2015 and December 2022 were prospectively collected. Standrardized ultrasound was used to examine the fetuses. For the suspected fetal CHD, the section of cardiac ultrasound was improved as far as possible, and ultrasonic results, prenatal diagnosis, pathological anatomy and pregnancy outcome were followed up. Results:A total of 539 cases of CHD were detected in 72 242 fetuses with mixed risk in the first trimester, the incidence was 0.75% (539/72 242). The incidence of CHD in the fetuses with positive soft markers was 9.20% (287/3 118), and the incidence of multiple fetal malformations was 16.22% (235/1 449). The diagnostic accordance rate of complex CHD was 97.42%. For complex CHD, the sensitivity, specificity, false positive rate and false negative rate of first-trimester ultrasound were 90.41%, 99.98%, 0.02%, 9.59%. Combined with the results of this study, the abnormal section model of complex CHD was recommended. A total of 252 cases underwent staining chromosomal microarray or gene sequencing, of which 42.46% (107/252) were positive.Conclusions:Standardized ultrasound examination has a very high detection rate for fetal CHD in the first trimester. Transverse scanning of the heart can significantly improve the display of gray scale cardiac section, and reference to the cardiac section pattern map is beneficial to the early diagnosis of fetal CHD.
