This paper systematically reviews the core concepts and lines of theoretical inheritance of major spleen-stomach theories in traditional Chinese medicine （TCM）， including spleen deficiency theory， spleen-stomach damp-heat theory， and liver-spleen disharmony theory. It is found that these theories have all undergone a developmental trajectory characterized by classical foundation， refinement of therapeutic methods， systematization of pathogenesis， and modern innovation. The evolution of spleen-stomach theory has achieved a shift from a singular focus on tonifying the spleen to regulating dynamic middle-jiao （焦） balance， and from localized spleen-stomach regulation to the circular movement of qi involving all five zang organs. In terms of modern disease-syndrome integrative research， spleen deficiency syndrome is shown to be closely associated with impairment of the gastrointestinal mucosal barrier， metabolic disorders， and gene polymorphisms related to Helicobacter pylori-associated gastric diseases. Spleen-stomach damp-heat syndrome is closely linked to hyperactive energy metabolism， inflammatory cytokines， and abnormal expression of aquaporins. Liver-spleen disharmony syndrome is mainly associated with dysregulation of the brain-gut axis and microbiota-related metabolic disorders. It is proposed that future research on spleen-stomach diseases and syndromes should further elucidate their potential multidimensional differential biological characteristics， thereby promoting the modernization of the TCM discipline of spleen-stomach studies.

OBJECTIVE To evaluate the efficacy and safety of dimethyl fumarate （DMF） in the treatment of multiple sclerosis （MS）. METHODS Retrieved from CBM， Web of Science， PubMed， the Cochrane Library， Embase， CNKI， Wanfang Data， and VIP， randomized controlled trials （RCTs） about DMF （trial group） versus other drugs or placebo （control group） were collected. After data screening and extraction， quality evaluation， meta-analysis was conducted by using RevMan 5.3 software. RESULTS A total of 6 literature were included， involving 638 patients. Results of meta-analysis showed that the proportion of patients with lesion changes after treatment in the trial group was lower than control group [MD＝－0.65， 95%CI（－1.27， －0.02）， P＝0.04]； there was no statistical significance in recurrence rate [RR＝1.06， 95%CI（0.52，2.17）， P＝0.88]， the proportion of patients with new lesions after treatment [RR＝1.05， 95%CI（0.62，1.80）， P＝0.85]， expanded disability status scale after treatment [MD＝0.02，95%CI （－0.18， 0.23）， P＝0.82]， the incidence of adverse events [RR＝1.33， 95%CI（0.97， 1.84）， P＝0.08] or severe adverse events [RR＝0.95，95%CI（0.48，1.90），P＝0.89] between 2 groups. Results of sensitivity analysis showed the study obtained unstable recurrence rate and the incidence of adverse events， while other results were robust. CONCLUSIONS DMF can control the lesion progression in MS patients to some extent and doesn’t increase the incidence of adverse events and serious adverse events， but there is no significant advantage in reducing the recurrence rate and controlling the disability progression.

The construction of standard system is an important part of standardization work， and also the top-level design of standardization work.Taking the group standards of the China Association of Chinese Medicine as a reference， and following the steps of establishing an expert group， literature research， Delphi method expert consultation and expert meeting， it was clarified that the content of the standard system for clinical diagnosis and treatment techniques of gastroenterology in traditional Chinese medicine， including terms （symptoms and signs， syndromes and syndrome components， and therapeutic principles and methods）， guidelines and standards （traditional Chinese medicine disease name， western medicine disease name， and classical syndromes）， effectiveness evaluation （modern medicine evaluation， traditional Chinese medicine characteristics of diseases， symptoms and signs grading， traditional Chinese medicine syndrome evaluation）， and practical techniques. Meanwhile， the structure chart of the standard system， the table of standard details and the table of statistical standards were compiled to lay the foundation for the standardisation of clinical diagnosis and treatment techniques of gastroenterology， and to provide reference for the construction of the standard system of various disciplines.

Background::Understanding willingness to undergo pulmonary function tests (PFTs) and the factors associated with poor uptake of PFTs is crucial for improving early detection and treatment of chronic obstructive pulmonary disease (COPD). This study aimed to understand willingness to undergo PFTs among high-risk populations and identify any barriers that may contribute to low uptake of PFTs.Methods::We collected data from participants in the "Happy Breathing Program" in China. Participants who did not follow physicians’ recommendations to undergo PFTs were invited to complete a survey regarding their willingness to undergo PFTs and their reasons for not undergoing PFTs. We estimated the proportion of participants who were willing to undergo PFTs and examined the various reasons for participants to not undergo PFTs. We conducted univariable and multivariable logistic regressions to analyze the impact of individual-level factors on willingness to undergo PFTs.Results::A total of 8475 participants who had completed the survey on willingness to undergo PFTs were included in this study. Out of these participants, 7660 (90.4%) were willing to undergo PFTs. Among those who were willing to undergo PFTs but actually did not, the main reasons for not doing so were geographical inaccessibility ( n = 3304, 43.1%) and a lack of trust in primary healthcare institutions ( n = 2809, 36.7%). Among the 815 participants who were unwilling to undergo PFTs, over half ( n = 447, 54.8%) believed that they did not have health problems and would only consider PFTs when they felt unwell. In the multivariable regression, individuals who were ≤54 years old, residing in rural townships, with a secondary educational level, with medical reimbursement, still working, with occupational exposure to dust, and aware of the abbreviation "COPD" were more willing to undergo PFTs. Conclusions::Willingness to undergo PFTs was high among high-risk populations. Policymakers may consider implementing strategies such as providing financial incentives, promoting education, and establishing community-based programs to enhance the utilization of PFTs.

Objective:To analyze the association between the pre-pregnancy oral microbiota of women and fetal overgrowth, and the possible mechanisms involved.Methods:A nested case-control study design based on a pre-pregnancy cohort was used to select 51 mothers who delivered macrosomia and/or large-for-gestational-age (LGA) infants from the population recruited at the Maternal and Child Health Care Hospital of Jiading District in Shanghai from October 2016 to December 2021 as the case group. A control group was formed by selecting 204 mothers who delivered infants with normal birth weight and appropriate for gestational age during the same period, in a 1:4 ratio. The LGA subgroup consisted of 48 mothers who delivered LGA infants from the total population, and a corresponding control group of 192 was randomly selected from the remaining mothers who delivered non-LGA infants in a 1∶4 ratio for the LGA subgroup analysis. The 16S rRNA gene sequencing technique was utilized to detect pre-pregnancy saliva samples to compare the characteristics of the oral microbiota, differential microorganisms, and differential functional pathways between groups. Nonparametric Wilcoxon rank-sum tests, two independent samples t-tests, or Chi-square (or Fisher's exact) tests were used for statistical analysis. Factor analysis was conducted on the pre-pregnancy diet data of women, and the primary dietary pattern of each study subject was identified based on the highest score of the dietary pattern factors. For microbiota count data, α and β diversity indices were calculated using R and QIIME2 software, and the corresponding microbiota functional count data were acquired through PICRUSt2. Results:(1) General data: There was no significant difference in the time interval from pre-pregnancy sampling to pregnancy and from sampling to delivery between the two groups. In the case group, there were three cases of macrosomia and 48 cases (94.1%) of LGA. The corresponding control group for the LGA subgroup consisted of 192 cases. There were no significant differences in dietary patterns between the case group and the control group. (2) α diversity analysis: The species richness index of the case group was lower than that of the control group [(367.27±84.57) vs. (408.71±93.08), multivariate analysis, P=0.009], while no significant differences were found between the two groups in the Shannon and Simpson indices; the species richness index of the LGA subgroup was also lower than that of the corresponding control group [(371.04±83.92) vs. (408.04±94.21), multivariate analysis, P=0.033], with no significant differences in the Shannon and Simpson indices. (3) β diversity analysis: There was a statistically significant difference in the unweighted UniFrac distance of the oral microbiota between the case group and the control group ( R2=0.006, F=1.479, P=0.048). No significant differences were found in the β diversity indices of the oral microbiota between the LGA subgroup and the corresponding control group. (4) Differential microbiota analysis: There were 14 differential microbiotas from phylum to genus between the case group and the control group. At the genus level, members of the G1 genus of the Streptococcaceae were enriched in the case group, while the Lautropia, Dialister, Leptotrichia, and Rothia were enriched in the control group. In the LGA subgroup and its corresponding control group, there were 14 differential microbiota from phylum to genus; at the genus level, Leptotrichia, Rothia, G6 genus of the Saccharibacteria, and Selenomonas were enriched in the control group (all LDA value>2, and all P<0.05). (5) Differential functional analysis: In the case group, metabolic pathways such as nicotinate degradation [log 2 fold change ( FC)=3.510, q=0.005], de novo synthesis of pyrimidine nucleotides (log 2FC=0.078, q=0.005), and L-tyrosine degradation pathway (log 2FC=0.710, q=0.034) were enriched in the oral microbiota of women. In the LGA subgroup, compared to the corresponding control group, metabolic pathways related to nicotinate degradation were enriched in the oral microbiota (log 2FC=3.660, q=0.012). Conclusions:There are differences in the structure of the pre-pregnancy oral microbiota of mothers with overgrown fetuses compared to those with normally grown fetuses, and mothers of normally grown fetuses show higher diversity in their pre-pregnancy oral microbiota. The enrichment of certain pathogenic bacteria and the reduction of symbiotic bacteria in the pre-pregnancy oral microbiota are associated with fetal overgrowth, and this association may be mediated by functional pathways such as nicotinate degradation.

OBJECTIVE: To explore the clinical manifestations and genetic characteristics of patients with congenital central hypothyroidism due to variants of IGSF1 gene. METHODS: Clinical data, results of genetic testing, and follow-up of four patients admitted to Children's Hospital of Soochow University during 2017 to 2021 were retrospectively analyzed. RESULTS: All of the four patients were males. Patient 1 had presented neonatal jaundice, patients 2 and 3 were admitted for growth retardation during childhood, and thyroid function test indicated slightly low free thyroxine (FT4), patient 4 was found to have reduced FT4 in the neonatal period. Genetic testing revealed that all of the four patients have harbored pathogenic variants of the IGSF1 gene, which were all inherited from their mothers. The thyroid functions in all patients were well controlled with oral levothyroxine and regular follow-up. CONCLUSION Pathogenic variants of the IGSF1 gene probably underlay the congenital central hypothyroidism with a variety of clinical manifestations, and genetic testing can facilitate the diagnosis at an early stage.

OBJECTIVE: To analyze the genetic characteristics of a child with Meier-Gorlin syndrome (MGS) due to a homozygous variant of the ORC6 gene. METHODS: A child who was admitted to the Children's Hospital Affiliated to Soochow University on March 25, 2019 due to growth retardation was selected as the study subject. Clinical data of the child was collected. Whole exome sequencing was carried out for the child. Candidate variant was validated by Sanger sequencing and bioinformatic analysis. RESULTS: The child, a 8-year-and-3-month-old male, has featured short stature, small ears, bilateral cryptorchidism and patellar dysplasia. His parents were of first cousins. The child was found to harbor a homozygous c.712A>T (p.K238*) missense variant of the ORC6 gene, which may lead to premature termination of protein translation. Sanger sequencing confirmed that both of his parents were heterozygous carriers. Based on the guidelines from the American College of Medical Genetics and Genomics, the variant was classified as pathogenic (PVS1_Moderate+PM2_Supporting+PM3+PP3+PP4). CONCLUSION The homozygous c.712A>T (p.K238*) variant probably underlay the MGS in this child.

To analyze the clinical features and genetic variants of a child with type 4 familial partial lipodystrophy (FPLD4) and the initial manifestation of diabetes.The male patient with the age of 13 years and 5 months, and the diabetes course was about 3 years, the patient was admitted to Children′s Hospital of Soochow University on November 10, 2021(4 th hospitalization at the hospital), in the course of diabetes, the children repeatedly suffered from diabetes ketoacidosis, and lipid metabolism complications gradually emerged.The gene sequencing showed that the proband and his mother carried dual gene mutations of PLIN1 c. 1325delG(p.G442Afs*99) and SPINK1 c. 194+ 2T>C(p.? ). The PLIN1 gene was the causal gene of FPLD4.The mutations of c. 1325delG in the PLIN1 gene had not been previously reported.Based on the clinical phenotype, family history and genetic testing findings, the patient was diagnosed as FPLD4.In addition, the mutation of SPINK1 c. 194+ 2T>C(p.? ) might increase the risk of chronic pancreatitis.This case report enriched the clinical characteristics and genotype data of FPLD4.Gene sequencing assisted the accurate diagnosis of the type of diabetes.The effects of dual gene mutations on disease progression should be concerned, which were of great significance to develop treatment regimen and disease management.

Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes(MELAS) is one of the most common inherited mitochondrial diseases. This paper reports a rare mutation associated with MELAS syndrome, the m. 3252 A>G mutation in the MT-TL1 gene encoding the mitochondrial tRNALeu(UUR). The 6-year-old girl suffered from recurrent convulsion and lactic acidemia. The mtDNA sequencing detected a variant m. 3252A>G(MT-TL1 gene) in the proband and her maternal relatives. The heteroplasmic levels in peripheral blood and urine sediment were 66.53% and 97.42%, respectively, which were obviously higher than those of her maternal relatives. Together with 3 previously reported cases, the variant m. 3252A>G could be classified pathogenic. All the reported pathogenic variants in MT-TL1 gene were reviewed to explore the genotype-phenotype correlations of pathogenic variants in MT-TL1 gene.

Objective: Based on observational, longitudinal and intervention study of common diseases among students in Jiangsu Province, this paper presents the current progress of two year follow up of myopia cohort regarding the association between growth parameters with progression of myopia among children and adolescents in areas with rapid economic growth. Methods: This survey adopted the stratified cluster sampling method for school selection. The full automatic computer optometry (TOPCON RM800) was used to track myopia related parameters for all participants from 2019 to 2020 under the condition of mydriasis (compound topicamide eye drops). Relationship between growth parameters of children and adolescents and the incidence and progression of myopia was analyzed by using Cox regression multiple statistical model. Results: The myopia rates of students from grade 1 to grade 3 in 2019 were 5.4%, 21.5% and 37.3% respectively. After one year, the myopia rates of all school stages increased to 25.3%, 43.3% and 58.1% respectively( χ 2=53.59, 49.63, 32.52, P <0.01). The mean diopter of right eye and left eye after mydriasis were ( 0.30± 1.24/0.39±1.26)D in 2019 and (-0.33±1.54/-0.19±1.55)D in 2020, respectively based on Cox multiple regression results, age ( HR =1.21, 95% CI =1.09-1.34), naked eye vision ( HR =0.08, 95% CI =0.07-0.11), height ( HR =0.98, 95% CI =0.97-0.99) showed a strong correlation with the incidence and progression of myopia( P <0.05). Conclusion Myopia is growing rapidly in the central region of Jiangsu Province. It is suggested that diopter, axial length, naked eye vision, age, height and other indicators should be included in the refractive archives of children and adolescents in the region.
