The health of the human body is the result of the dynamic interplay between immunity and various microorganisms. Furthermore, the health of the mitochondrial grid determines the strength of immunity. Mitochondrial imbalance leads to the metabolic remodeling of intracellular nutrients, which accelerates the occurrence and development of tumors. The theory of yin and yang and the theory of visceral outward manifestation are the foundation and core of traditional Chinese medicine (TCM) theory, which guides the clinical diagnosis and treatment of TCM. Yang Qi is the driving force behind the metabolism and physiological functions of the human body; it is also the adenine nucleoside triphosphate produced efficiently by mitochondrial aerobic respiration. The main transport of spleen refers to the biological oxidation process of food in the mitochondria, and its normal function is closely related to the integrity of the mitochondrial structure and function of the cell. Therefore, warming yang and strengthening the spleen essentially means restoring the high production capacity of the mitochondria. Rebuilding damaged mitochondrial function, improving efficiency, and boosting the energy level of the neuro-endocrine-immune network are the key factors contributing to the body’s ability to resist disease and return to health.

Objective:To investigate the clinical efficacy of bilateral V-Y advancement island flaps on buttocks in repairing postoperative defects in patients with perianal Paget′s disease.Methods:From January 2009 to January 2021, a retrospective analysis was performed on clinical data collected from 13 patients with perianal Paget′s disease, whose perianal defects resulting from the tumor resection were reconstructed with bilateral V-Y advancement island flaps on the buttocks in the Department of Dermatology, Hangzhou Third People′s Hospital. The postoperative recovery of the buttocks and the effects on the defecation function were evaluated.Results:The areas of perianal defects in 13 cases ranged from 4.8 cm × 5.6 cm to 12.2 cm × 6.4 cm. All defects were successfully repaired by using the bilateral V-Y advancement island flaps, and all surgical wounds healed primarily. One case first received temporary ileostomy, and then received ileostomy closure 3 months later, resulting in the recovery of defecation function; in another 1 case of perianal Paget′s disease comorbid with rectal cancer, the permanent sigmoid colostomy was performed to divert feces, and the defecation function was lost. After the follow-up for 1 - 6 years, the buttocks were symmetrical in shape in all the 13 patients, and 12 with preserved anus had normal defecation function. No tumor recurrence was observed in 12 patients without other malignant tumors after the operation, while 3 patients experienced mild anal stenosis without anal mucosa eversion or wound dehiscence; 1 patient with perianal Paget′s disease complicated by anal canal adenocarcinoma developed bilateral inguinal lymph node and internal iliac lymph node metastasis 1 year after the operation, and died 6 months later.Conclusion:The bilateral V-Y advancement island flaps on the buttocks have the advantages of reliable blood supply and sufficient advancement mobility, and can be used to repair large skin defects around the anus.

Objective:To assess the association between short-term ambient air pollution exposure and arterial stiffness and whether obesity modifies these associations.Methods:A cross-sectional study was conducted based on Fangshan family cohort in Beijing. The 24 hours average air pollutant levels on the day cohort participants took baseline survey were calculated as short-term air pollution. A generalized additive model (GAM) with Gaussian links was used to estimate changes in typical carotid artery intima-media thickness (CIMT), brachial-ankle pulse wave velocity (BAPWV), pulse pressure (PP) and ankle-branchial index (ABI) after short-term exposure to each air pollution (PM 2.5, PM 10, SO 2, NO 2, CO). The cross-product terms of each air pollution, body mass index (BMI), and waist-to-hip ratio were included in the GAM model to test the interaction. Further, they conducted a stratified analysis to test their effects on the relationship between short-term exposure to each air pollution and the arterial stiffness indicators. Results:A total of 4 211 individuals were included in the analysis. Individuals' age was (58.9±8.7) years, of which 2 268 (53.9%) were female. Several covariates, including sociodemographic factors, lifestyle behaviors, and history of drugs, were included in the analysis. The results of the GAM analysis showed that an increase in PM 2.5 ( β=2.912×10 -4, 95% CI: 1.424×10 -4-4.400×10 -4, P<0.001), CO ( β=0.027, 95% CI: 0.011-0.043, P<0.001), SO 2 ( β=2.070×10 -3, 95% CI: 7.060×10 -4-3.430×10 -3, P=0.003), and NO 2 ( β=3.650×10 -4, 95% CI: 2.340×10 -5-7.060×10 -4, P=0.036) were associated with an increase in CIMT, while an increase in PM 10 ( β=0.018, 95% CI: 0.002-0.033, P=0.028) was associated with an increase in PP in the study population. Besides, the waist-to-hip ratio had an effect-modification on the correlation of short-term exposure of PM 2.5 (interaction P=0.015), NO 2 (interaction P=0.008), and CO (interaction P=0.044) with CIMT, and the correlation between short-term exposure of PM 2.5 (interaction P=0.002), NO 2 (interaction P=0.010), CO (interaction P=0.029), PM 10 (interaction P<0.001) with PP. The significant association between CIMT, PP, and air pollution concentrations was more visible in people with lower waist-to-hip ratios. Conclusions:Short-term ambient air pollution exposure was associated with arterial stiffness indicators, and there was an effect modification of waist-to-hip ratio on these associations, and lower waist-to-hip ratios may enhance the association between air pollution exposure and indicators.

Purpose To investigate the abnormal brain development in fetuses with isolated mild to moderate ventriculomegaly(VM)during the second and third trimesters of pregnancy by using semi-quantitative fetal total maturation score(fTMS).Materials and Methods A retrospective analysis was performed on 45 normal fetuses and 78 abnormal fetuses who underwent fetal MRI in the General Hospital of Ningxia Medical University from January 2018 to October 2022.fTMS was used to score all images.Linear regression was used to assess the relationship between fTMS and gestational age between normal and abnormal fetuses and to analyze the differences between fetuses with isolated mild and moderate VM and controls.Results In the control group,fetal fTMS was significantly positively correlated with gestational age(r=0.939,P<0.05).The linear regression equation between fTMS(Y)and gestational age(X)was as follows:Y=-28.1+1.25X.In the mild and moderate isolated VM groups,fTMS was positively correlated with gestational age(r=0.945,0.906,P<0.05).The linear regression equations of fTMS(Y)and gestational age(X)were:Y=-28.46+1.24X,Y=-25.57+1.13X.The average fTMS of healthy fetus,mild VM and moderate VM were(10.55±4.25)points,(10.13+4.08)points and(9.22±3.77)points,respectively.There was no significant difference in fTMS between the 49 fetuses with mild isolated VM and the control group(t=1.651,P>0.05).There was significant difference in fTMS between the 29 fetuses with moderate isolated VM and the control group(t=2.306,P<0.05).Conclusion fTMS is suitable for routine clinical use and sensitive to differences in brain maturation between fetuses with isolated moderate VM and healthy controls.

Systemic rheumatic disease is a kind of autoimmune disease which is caused by the dys-function of autoimmune cells and the damage of multiple systems and organs.Traditional immuno-suppressants play an important role in the treat-ment of systemic rheumatic diseases,but there are still a considerable number of refractory systemic rheumatic diseases that do not respond well to tra-ditional immunosuppressant therapy,and new ther-apeutic methods need to be explored.Chimeric an-tigen receptor T cell therapy(CAR-T)immunothera-py was initially used for the treatment of malig-nant hematological diseases and has shown good efficacy.Recently,CAR-T immunotherapy has also achieved remarkable efficacy in refractory systemic lupus erythematosus.It brings new hope for the treatment of systemic rheumatic diseases.This arti-cle summarizes the progress of clinical application of CAR-T immunotherapy in systemic rheumatic dis-eases in recent years,aiming to enhance clinicians'cognition of CAR-T immunotherapy and promote the further development of CAR-T immunotherapy in systemic rheumatic diseases.

Objective:To explore the effects of short-term particulate matter(PM)exposure and the melatonin receptor 1B(MTNR1B)gene on triglyceride-glucose(TyG)index utilizing data from Fang-shan Family-based Ischemic Stroke Study in China(FISSIC).Methods:Probands and their relatives from 9 rural areas in Fangshan District,Beijing,were included in the study.PM data were obtained from fixed monitoring stations of the National Air Pollution Monitoring System.TyG index was calculated by fasting triglyceride and glucose concentrations.The associations of short-term PM exposure and rs10830963 polymorphism of the MTNR1B gene with the TyG index were assessed using mixed linear models,in which covariates such as age,sex,and lifestyles were adjusted for.Gene-environment inter-action analysis was furtherly performed using the maximum likelihood methods to explore the potential effect modifier role of rs10830963 polymorphism in the association of PM with TyG index.Results:A total of 4 395 participants from 2 084 families were included in the study,and the mean age of the study participants was(58.98±8.68)years,with 53.90％females.The results of association analyses showed that for every 10 μg/m3 increase in PM2.5 concentration,TyG index increased by 0.017(95％CI:0.007-0.027),while for per 10 μg/m3 increment in PM1o,TyG index increased by 0.010(95％CI:0.003-0.017).And the associations all had lagged effects.In addition,there was a positive association between the rs10830963 polymorphism and the TyG index.For per increase in risk allele G,TyG index was elevated by 0.040(95％CI:0.004-0.076).The TyG index was 0.079(95％CI:0.005-0.152)higher in carriers of the GG genotype compared with carriers of the CC genotype.The inter-action of rs10830963 polymorphism with PM exposure had not been found to be statistically significant in the present study.Conclusion:Short-term exposure to PM2.5 and PM10 were associated with higher TyG index.The G allele of rs10830963 polymorphism in the MTNR1B gene was associated with the elevated TyG index.

Objective:To explore the association between polymorphisms of transforming growth factor-β(TGF-β)signaling pathway and non-syndromic cleft lip with or without cleft palate(NSCL/P)among Asian populations,while considering gene-gene interaction and gene-environment interaction.Methods:A total of 1 038 Asian NSCL/P case-parent trios were ascertained from an international consortium,which conducted a genome-wide association study using a case-parent trio design to investigate the genes affec-ting risk to NSCL/P.After stringent quality control measures,343 single nucleotide polymorphism(SNP)spanning across 10 pivotal genes in the TGF-β signaling pathway were selected from the original genome-wide association study(GWAS)dataset for further analysis.The transmission disequilibrium test(TDT)was used to test for SNP effects.The conditional Logistic regression models were used to test for gene-gene interaction and gene-environment interaction.Environmental factors collected for the study in-cluded smoking during pregnancy,passive smoking during pregnancy,alcohol intake during pregnancy,and vitamin use during pregnancy.Due to the low rates of exposure to smoking during pregnancy and al-cohol consumption during pregnancy(＜3％),only the interaction between maternal smoking during pregnancy and multivitamin supplementation during pregnancy was analyzed.The threshold for statistical significance was rigorously set at P=1.46 × 10-4,applying Bonferroni correction to account for multiple testing.Results:A total of 23 SNPs in 4 genes yielded nominal association with NSCL/P(P＜0.05),but none of these associations was statistically significant after Bonferroni's multiple test correction.How-ever,there were 6 pairs of SNPs rs4939874(SMAD2)and rs1864615(TGFBR2),rs2796813(TGFB2)and rs2132298(TGFBR2),rs4147358(SMAD3)and rs1346907(TGFBR2),rs4939874(SMAD2)and rs1019855(TGFBR2),rs4939874(SMAD2)and rs12490466(TGFBR2),rs2009112(TGFB2)and rs4075748(TGFBR2)showed statistically significant SNP-SNP interaction(P＜1.46 × 10-4).In contrast,the analysis of gene-environment interactions did not yield any significant results after being cor-rected by multiple testing.Conclusion:The comprehensive evaluation of SNP associations and interac-tions within the TGF-β signaling pathway did not yield any direct associations with NSCL/P risk in Asian populations.However,the significant gene-gene interactions identified suggest that the genetic architec-ture influencing NSCL/P risk may involve interactions between genes within the TGF-β signaling path-way.These findings underscore the necessity for further investigations to unravel these results and further explore the underlying biological mechanisms.

Objective:To develop the Chinese version of the adolescent lifestyle profile-revised 2 (ALP-R2) and evaluate its reliability and validity.Methods:The original ALP-R2 was translated into Chinese edition, then tested by random sampling in middle school students.SPSS 23.0 and AMOS 17.0 were conducted exploratory factor analysis and confirmatory factor analysis to evaluate the reliability and validity of the Chinese version of ALP-R2.Results:(1) The Chinese version of ALP-R2 contained 43 items through item analysis, then exploring factor analysis showed that it contained 7 sub-scales(F1: health responsibility, F2: physical activity, F3: nutrition, F4: positive life perspective, F5: stress management, F6: spiritual health, F7: interpersonal relationships)with 40 items, and could explain 61.044% of the total variances. (2) The results of confirmatory factor analysis showed that the revised ALP-R2 had good construct validity( χ2/ df=4.97, GFI=0.98, NNFI=0.97, CFI=0.90, RMSEA=0.12). The scores of various factors in ALP-R2 were significantly correlated with the total score of Chinese adolescent lifestyles scale(CALS)( r=0.38-0.65, all P<0.05). (3) Internal consistency reliability was 0.711-0.801, the test-retest reliability was 0.723-0.822, and split-half reliability was 0.708-0.845. Conclusion:The Chinese version of ALP-R2 has good reliability and acceptable validity, and can be used to evaluate the lifestyle of adolescents.

Objective:To summarize and analyze the efficacy of the upper eyelid orbicularis oculi myocutaneous island flap in repairing secondary defects after resection of eyelid and periorbital skin tumors.Methods:A retrospective analysis was carried out on clinical data collected from 28 patients, whose secondary eyelid and periorbital defects were repaired with the upper eyelid orbicularis oculi myocutaneous island flaps in the Department of Dermatology, Hangzhou Third People′s Hospital from August 2019 to June 2021. The survival condition of the flaps was observed after the operation, and the appearance of the upper eyelid and periorbital skin as well as tumor recurrence were evaluated during the follow up.Results:Among the 28 cases, there were 6 males and 22 females; their ages ranged from 47 to 87 years (70.5 ± 10.9 years), 7 patients were aged 80 - 89 years, 8 aged 70 - 79 years, 8 aged 60 - 69 years, 4 aged 50 - 59 years, and 1 patient was aged 40 - 49 years. Skin defects were distributed at the upper eyelid in 1 case, at the lower eyelid in 9 cases, at the inner canthus in 1 case, at the outer canthus in 3 cases, at the upper eyebrow in 1 case, at the dorsum of the nose in 3 cases, and at the junction of the external nose, inner canthus and lower eyelid in 10 cases. The skin defects varied from 1.0 cm × 0.5 cm to 3.1 cm × 2.3 cm in size. The designed upper eyelid orbicularis oculi myocutaneous flap was 0.5 - 1.8 cm in width and 3 - 4 cm in length, and the length of the subcutaneous tunnel was 1.2 - 2.5 cm. During the follow-up of 6 months to 1.5 years, all flaps survived; scars on the upper eyelid donor sites were not obvious; there was no upper eyelid ectropion, no trichiasis, and no eyelid closure abnormality after the operation.Conclusion:The medium- or small-sized defects of the eyelid and periorbital skin can be successfully repaired by the upper eyelid orbicularis oculi myocutaneous island flap, with a favorable cosmetic effect and concealed donor areas.

Objective:To investigate the application of transverse closure of longitudinal incisions in repairing pentagonal full-thickness defects of the lower eyelid margin.Methods:A retrospective analysis was performed on clinical data collected from 26 patients with melanocytic nevi at the lower eyelid margin in Department of Dermatology, The Third People′s Hospital of Hangzhou from July 2016 to June 2019. Among the 26 patients, 10 were males, and 16 were females. After lesion resection, all the pentagonal full-thickness defects of the lower eyelid margin were repaired via transverse closure of longitudinal incisions.Results:All the pentagonal defects of the 26 cases were successfully repaired. The longitudinal incisions perpendicular to the eyelid were successfully converted into transverse incisions parallel to the eyelid margin and near the eyelash, and all incisions healed primarily. After surgery, mild congestion of the lower eyelid occurred in 3 patients, and temporary blurred vision in 1. During 1 - 2 years of postoperative follow-up, 26 patients all achieved symmetrical appearance of the skin and soft tissues around the eyes, without obvious postoperative scars or lower eyelid ectropion.Conclusions:Horizontal closure of longitudinal incisions can be used to repair the pentagonal full-thickness defects of the lower eyelid margin, because it can convert the incision closure line perpendicular to the lower eyelid margin into a horizontal transverse incision closure line parallel to the lower eyelid margin, so that the incisions and scars of the lower eyelid can be hided with a satisfactory cosmetic effect.
