Objective:To assess iodine nutritional status and the prevalence of thyroid dysfunction in Kunming, Yunnan Province, along with correlation and risk factors between thyroid dysfunction and urinary iodine levels.Methods:This cross-sectional study was conducted from January 2014 to July 2016 using a multi-stage, stratified cluster sampling method. A total of 2 650 residents of Kunming, Yunnan Province, who met the inclusion criteria were selected. Data on participants′ demographics, physical measurements, and laboratory tests were collected through questionnaire and clinical assessments which led to 1 463 subjects in the final analysis considering missing data. Statistical analysis were performed using SPSS 26.0, while R Studio was used to model the nonlinear relationship between urinary iodine levels and the risk of thyroid dysfunction.Results:(1) Among 2 650 subjects, 755(28.5%) were diagnosed with thyroid dysfunction, with incidence rates of clinical hyperthyroidism(0.83%), subclinical hyperthyroidism(0.38%), clinical hypothyroidism(1.36%), subclinical hypothyroidism(17.66%), and isolated thyroid antibody positive(13.85%). The median urinary iodine concentration was 177.49(123.59, 251.85) μg/L, indicating adequate iodine nutritional. (2)Among the 1 463 subjects analyzed, significant differences in urinary iodine were found between healthy individual group and abnormal TSH group or abnormal TSH group and thyroid antibody positive group( H=-83.437, P=0.003; H=107.489, P=0.003). Logistic regression revealed that rural residents had a lower risk of thyroid dysfunction than urban residents( OR=0.429, 95% CI 0.256-0.717, P=0.001). Risk of thyroid disease increased with age, and TSH, thyroid peroxidase antibody(TPOAb), thyroglobulin antibody(TgAb), and urinary iodine levels were identified as significant risk factors, with a U-shaped relationship between urinary iodine levels and thyroid dysfunction. Conclusions:The prevalence of thyroid dysfunction in Kunming is comparable to the national average. The relationship between urinary iodine concentration and thyroid dysfunction follows a U-shaped curve. Factors including region, age, TSH, TPOAb, TgAb, and urinary iodine concentration are associated with thyroid dysfunction.

AIM To explore the clinical effects of Jiawei Yanghe Decoction combined with Budesonide and Formoterol Fumarate Powder for Inhalation on patients with mild to moderate bronchial asthma in chronic and persistent period.METHODS One hundred and eighteen patients were randomly assigned into control group(59 cases)for 4-week administration of Budesonide and Formoterol Fumarate Powder for Inhalation,and observation group(59 cases)for 4-week administration of both Jiawei Yanghe Decoction and Budesonide and Formoterol Fumarate Powder for Inhalation.The changes in clinical effects,ACT score,bronchial asthma control rate,pulmonary function indices(FEV1,PEF,FEV1％,PEF％),inflammatory indices(EOS,EOS％,FeNO),TCM syndrome score and incidence of adverse reactions were detected.RESULTS The observation group demonstrated higher total effective rate than the control group(P＜0.05).After the treatment,the two groups displayed increased bronchial asthma control rate,ACT score,PEF(P＜0.05),and decreased TCM syndrome score(P＜0.05),especially for the observation group(P＜0.05);the observation group exhibited increased FEV1,FEV1％,PEF％(P＜0.05),among which FEV1,PEF％were higher than those in the control group(P＜0.05);the observation group showed decreased inflammatory indices(P＜0.05),among which FeNO was lower than that in the control group(P＜0.05).No significant difference in incidence of adverse reactions was found between the two groups(P＞0.05).CONCLUSION For the patients with mild to moderate bronchial asthma in chronic and persistent period,Jiawei Yanghe Decoction combined with Budesonide and Formoterol Fumarate Powder for Inhalation can safely and effectively alleviate clinical symptoms,improve pulmonary functions,airway inflammatory reactions,and enhance bronchial asthma control rate.

Objective To explore the mechanism of Bufei Jiedu Granules in the treatment of methicillin-resistant Staphylococcus aureus(MRSA)chronic infection using network pharmacology;To verify it through animal experiments.Methods Active components and potential targets in Bufei Jiedu Granules were screened through the TCMSP database,and genes related to MRSA infection were retrieved through GeneCards,OMIM,DisGeNET,TTD,DrugBank and PharmGKB databases.The STRING database was employed to construct a protein-protein interaction network on common targets,and GO and KEGG pathway enrichment analysis were conducted to identify key signaling pathways for Bufei Jiedu Granules treatment of MRSA infection.The effects of Bufei Jiedu Granules on bacterial load and pathological changes in the lung,liver and kidney of MRSA chronic infection mice models were evaluated through WT and T/B immune cell deficient Rag2-/-mouse animal experiments.The mRNA expressions of inflammatory factors(IFN-γ,IL-10)and immune checkpoints(PD1,TIM3)were detected.Results Totally 54 active components related to Bufei Jiedu Granules were selected,and 50 potential targets related to MRSA infection were identified.118 signaling pathways significantly associated with MRSA infection were identified through GO and KEGG pathway enrichment analysis,in which the JAK-STAT signaling pathway,Th17 cell differentiation,and PD-L1 expression and PD-1 checkpoint pathway were closely related to cell activation and T cell differentiation.Animal experimental results indicated that Bufei Jiedu Granules could effectively reduce the bacterial load in organs and ameliorate the pathological damage in the chronic MRSA infection mouse model,increase the mRNA expression of IFN-γ in the lung tissue,and decrease the mRNA expressions of IL-10,PD1 and TIM3.Conclusion Bufei Jiedu Granules has the characteristics of multi-component and multi-target in the treatment of MRSA infection,and may be involved in adaptive immune activation to effectively treat chronic MRSA infection.

Mesenchymal stem cells have emerged as a promising cell therapy for anti-tumor research due to their homing properties,low immunogenicity,anti-angiogenic activity,anti-inflammatory properties,and paracrine effects.Paclitaxel has been clinically used for over thirty years in the treatment of various tumors such as ovarian cancer,lung cancer,and breast cancer.However,the broad-spectrum anti-tumor properties of paclitaxel are not possessed by the aforementioned cell therapies.Moreover,its adverse reactions,including peripheral neuropathy,bone marrow suppression,and gastrointestinal reactions,have long plagued cancer patients.In recent years,many studies have focused on combining cell therapy with chemotherapy to achieve better treatment outcomes,giving rise to a new drug delivery system that utilizes mesenchymal stem cells as carriers for delivering chemotherapeutic drugs.This review summarizes the research progress in MSC-based drug delivery systems for paclitaxel.

Malignancies are a difficult to treat disease in clinical practice.At present,there are many cases of differentiation and treatment based on qi and yin deficiency,the coagulation of phlegm,blood stasis and cancer toxin,there are few theories on the treatment of yang deficiency and yin excessiveness,as well as the coagulation of cold and dampness.On the basis of inheriting the cancer toxin theory of Chinese medicine master ZHOU Zhongying,combined with the theory of promoting yang and our own practice,we believe that malignancy is caused by yang deficiency as the foundation,cold dampness,phlegm-turbidity stagnation and toxin transformation as the manifestation,and the key pathogenesis can be summarized as yang deficiency and yin binding.Based on this,it is proposed to differentiate and treat malignancies from promoting yang and eliminating yin.The method of promoting yang and eliminating yin is people-oriented,with harmony as the value,based on the whole,with a focus on adjusting harmony,constantly promoting yang and timely eliminating yin.The specific differentiation and treatment strategies are as follows:in the early stages of malignancy,it is important to seize the opportunity to warm and dredge,or eliminate yin;malignancy is already present,balancing deficiency and excess,supplementing,eliminating,and harmonizing appropriately;after malignancy surgery,it is important to strengthen the foundation and regulate the spleen and kidney,and strengthen both congenital and acquired constitution;treating the zang-fu organs accordingly,elevating and lowering,and conforming to the physiology of the organs.Unlike simple malignancy treatment and detoxification,promoting yang and eliminating yin is a method of examining symptoms and identifying etiology and pathogenesis.It involves macroscopic regulation of yin and yang,dynamic management of medication,and orderly treatment,which can significantly improve the quality of life of patients and increase long-term survival rates.Exploring the theory and strategy of promoting yang and eliminating yin in the differentiation and treatment of malignancy can provide new ideas and references for the clinical differentiation and treatment of malignancies.

Objective:To investigate the causal correlation between depression and stress urinary incontinence(SUI)using Mendelian randomization(MR)analysis.Methods:We searched the FinnGen Consortium database for genome-wide association studies(GWAS)on depression and obtained 23 424 case samples and 192 220 control samples,with the GWAS data on SUI provided by the UK Biobank,including 4 340 case samples and 458 670 control samples.We investigated the correlation between depression and SUI based on the depression data collected from the Psychiatric Genomics Consortium(PGC).We employed inverse-variance weighting as the main method for the MR study,and performed sensitivity analysis to verify the accuracy and stability of the findings.Results:Analysis of the data from the UK Biobank and FinnGen Consortium showed that depression was significantly correlated with an increased risk of SUI(P=0.005),but not SUI with the risk of depression(P=0.927).And analysis of the PGC data verified the correlation of depression with the increased risk of SUI(P=0.043).Conclusion:Depression is associated with an increased risk of SUI,while SUI does not increase the risk of depression.

Background: We aimed to investigate the characteristics of pediatric ulcerative colitis (UC) at diagnosis in Korea. Methods: This was a multicenter, registry-based, inception cohort study conducted in Korea between 2021 and 2023. Children and adolescents newly diagnosed with UC < 18 years were included. Baseline clinicodemographics, results from laboratory, endoscopic exams, and Paris classification factors were collected, and associations between factors at diagnosis were investigated. Results: A total 205 patients with UC were included. Male-to-female ratio was 1.59:1, and the median age at diagnosis was 14.7 years (interquartile range 11.9–16.2). Disease extent of E1 comprised 12.2% (25/205), E2 24.9% (51/205), E3 11.2% (23/205), and E4 51.7% (106/205) of the patients. S1 comprised 13.7% (28/205) of the patients. The proportion of patients with a disease severity of S1 was significantly higher in patients with E4 compared to the other groups (E1: 0% vs. E2: 2% vs. E3: 0% vs. E4: 24.5%, P < 0.001). Significant differences between disease extent groups were also observed in Pediatric Ulcerative Colitis Activity Index (median 25 vs. 35 vs. 40 vs. 45, respectively, P < 0.001), hemoglobin (median 13.5 vs.13.2 vs. 11.6 vs. 11.4 g/dL, respectively, P < 0.001), platelet count (median 301 vs. 324 vs. 372 vs. 377 × 103 /μL, respectively, P = 0.001), C-reactive protein (median 0.05 vs. 0.10 vs. 0.17 vs. 0.38 mg/dL, respectively, P < 0.001), and Ulcerative Colitis Endoscopic Index of Severity (median 4 vs. 4 vs. 4 vs. 5, respectively, P = 0.006). No significant differences were observed in factors between groups divided according to sex and diagnosis age. Conclusion This study represents the largest multicenter pediatric inflammatory bowel disease cohort in Korea. Disease severity was associated with disease extent in pediatric patients with UC at diagnosis.
