Objective To investigate the correlation between insulin resistance and interleukin-6 (IL-6), chemerin, total cholesterol (TC)/high density lipoprotein cholesterol (HDL-C) ratio, triglyceride (TG)/HDL-C ratio, low density lipoprotein cholesterol (LDL-C)/HDL-C ratio and insulin resistance in obese patients with type 2 diabetes mellitus (T2DM), and to provide scientific basis for T2DM prevention and control. Methods A total of 355 obese T2DM patients in Songjiang Hospital Affiliated to Shanghai Jiaotong University School of Medicine were selected from January 2021 to December 2023. IL-6, chemerin and lipids were detected, and the assessment of insulin resistance was conducted through the homeostasis model assessment of insulin resistance (HOMA-IR). Results Among the 355 obese T2DM patients, there were 280 cases of insulin resistance, with the incidence rate of 78.87%. The BMI, IL-6, chemerin, TC/HDL-C, LDL-C/HDL-C, and TG/HDL-C in the insulin resistance group were higher than those in the non-insulin resistance group (P<0.05). The above insulin resistant patients were divided into 4 subgroups by means of insulin resistance, and there were significant differences in BMI, IL-6, chemerin, and TG/HDL-C among the subgroups (P<0.05). IL-6, chemerin, and TG/HDL-C were positively correlated with HOMA-IR in obese T2DM patients (P<0.05), while TC/HDL-C and LDL-C/HDL-C had no significant correlation with HOMA-IR (P>0.05). BMI, IL-6, chemerin, and TG/HDL-C were all influencing factors of insulin resistance in obese T2DM patients (P<0.05). Conclusion IL-6, chemerin and TG/HDL-C are correlated with insulin resistance in obese patients with T2DM and are influencing factors for the occurrence of insulin resistance.

ObjectiveTo explore the characteristics of traditional Chinese medicine （TCM） syndromes in the patients with concurrent knee osteoarthritis （KOA） and postmenopausal osteoporosis （PMOP） and provide a scientific basis for precise TCM syndrome differentiation， diagnosis， and treatment of such concurrent diseases. MethodsA prospective， multicenter， cross-sectional clinical survey was conducted to analyze the characteristics of TCM syndromes in the patients with concurrent PMOP and KOA. Excel 2021 was used to statistically analyze the general characteristics of the included patients. Continuous variables were reported as x¯±s， and binary variables were reported as percentages. UCINET and Gephi were used to construct a complex "isease-syndrome-symptom" network for in-depth mining. Topological structure indicators， edge connection information between nodes， and weighted adjacency matrices were calculated by UCINET and Python. Gephi was used for complex network visualization. ResultsA total of 157 patients with concurrent PMOP and KOA from 12 TCM hospitals or community health service centers were selected for the collection of TCM syndrome and symptom information. A total of 4 main TCM syndromes were obtained， which were kidney-Yang deficiency （47.13%）， liver-kidney Yin deficiency （36.94%）， spleen-kidney Yang deficiency （8.92%）， and kidney Yin-Yang deficiency （7.01%）. In addition， 10 concurrent syndromes （mainly Qi stagnation and blood stasis， Qi and blood deficiency， spleen Yang deficiency， and cold-dampness） were identified. Based on the results of comprehensive frequency statistics and complex network analysis， as well as TCM theoretical knowledge and relevant guidelines， the general characteristics of concurrent PMOP and KOA and the main TCM syndromes in the dimensions of physical symptoms， pain， tongue and pulse manifestations， and defecation and urination were obtained. ConclusionThe main TCM syndromes in the patients with concurrent PMOP and KOA may be kidney Yang deficiency， liver-kidney Yin deficiency， spleen-kidney Yang deficiency， and kidney Yin-Yang deficiency， among which kidney Yang deficiency and liver-kidney Yin deficiency are the core TCM syndromes.

Objective: To investigate the vitamin D levels in children aged 1 year in Shaoxing City, Zhejiang Province, so as to provide the basis for prevention and treatment of vitamin D deficiency in children and promoting their health. Methods: The 1-year-old children who underwent health examinations at the Department of Child Health Care of Shaoxing Maternal and Child Health Care Hospital from September 2023 to August 2024 were selected. Basic information of the children was collected through the medical record information system, and their length and weight were measured. The length, weight and nutritional status were evaluated according to the Technical Specifications for the Management of Nutritional Diseases in Children. Serum 25-hydroxyvitamin D [25- (OH) D] levels were measured using electrochemiluminescence assay, and vitamin D levels were assessed based on the fifth edition of Child Health Care. The vitamin D levels were analyzed among the children with different genders, testing months, and growth status. Results: A total of 2 245 children were recruited, including 1 189 boys (52.96%) and 1 056 girls (47.04%). The median serum 25- (OH) D level was 39.98 (interquartile range, 16.63) ng/mL. Vitamin D insufficiency was observed in 279 children, with an insufficiency rate of 12.43%. The median serum 25- (OH) D level in boys was 39.26 (interquartile range, 17.75) ng/mL, which was lower than that in girls at 41.39 (17.75) ng/mL (P<0.05). The vitamin D insufficiency rate was 13.04% in boys and 11.74% in girls, with no statistically significant difference (P>0.05). The lowest vitamin D insufficiency rate was observed in August at 4.95%, while the highest rate was in September at 23.89%, showing the statistically significant difference across testing months (P<0.05). The children with above-average length ratings, higher weight ratings and obesity had higher vitamin D insufficiency rates, at 17.29%, 20.86% and 20.88%, respectively. The vitamin D insufficiency rate increased with higher weight and nutritional status ratings (both P<0.05), but no significant change was observed with higher length ratings (P>0.05). Conclusions The vitamin D insufficiency rate among 1-year-old children in Shaoxing City was 12.43%, with variations observed in different testing months, weight and nutritional status. Targeted prevention and intervention measures should be implemented to address these differences.

Objective: To explore the factors affecting language development delay among children aged <3 years, so as to provide a basis for the prevention and early intervention of children's language development problems. Methods: Eighty-one children aged <3 years with language development delay who visited the children's language development clinic of Shaoxing Maternal and Child Health Hospital from January to December 2024 as the case group. Meanwhile, 118 children who underwent routine physical examinations at the children's health clinic during the same period, had normal language development were randomly selected as the control group. Data on children's basic information, parenting environment, and screen exposure were collected through questionnaire surveys. Language development delay was assessed using the Early Language Milestone Scale and the Gesell Developmental Diagnosis Scale. The factors for language development delay were analyzed using a multivariable logistic regression model. Results: The case group comprised 81 children, including 56 boys (69.14%) and 25 girls (30.86%), with a mean age of (23.14±4.84) months. The control group consisted of 118 children, including 81 boys (68.64%) and 37 girls (31.36%), with a mean age of (23.81±4.60) months. Multivariable logistic regression analysis showed that daily parental companionship time of ≥2 hours (OR=0.121, 95%CI: 0.040-0.367), attending childcare institutions (OR=0.103, 95%CI: 0.030-0.352), the average daily screen exposure time <1 hour (OR=0.614, 95%CI: 0.400-0.942), interactive parental accompaniment during screen exposure (OR=0.350, 95%CI: 0.157-0.779), and restricting screen exposure time (OR=0.162, 95%CI: 0.056-0.470) were associated with a lower risk of language development delay among children aged <3 years. Conclusion Daily paternal companionship of 2 hours or more, attending childcare institutions, daily screen exposure time of less than 1 hour, interactive parental companionship during screen time, and limiting screen exposure time can reduce the risk of language developmental delay among children aged under 3 years.

Objective To analyze the effectiveness and safety of bisphosphonates in the treatment of pa-tients with calcification defense.Methods PubMed,Embase databases,CNKI and Wanfang were searched to collect the case reports and clinical studies of bisphosphonates for calcification defense.Then,the relevant infor-mation of patients was extracted for statistical analysis.Results A total of 18 case reports were selected involving 20 patients.Thirteen patients(65.0％)were treated with pamidronate,four(20.0％)were treated with etidr-onate,two(10.0％)were treated with alendronate,and one(5.0％)was treated with zoledronic acid.Thirteen patients(65.0％)recovered completely,the recovery time of whom ranged from half month to nine months.The tolerance of bisphosphonates in most patients(90.0％)was good,while one patient who did not tolerate pamidr-onate recovered after the frequency of administration was adjusted and one patient with high dosage of etidronate returned to normal after the discontinuation of the usage.Conclusions Bisphosphonates,an inhibitor of bone resorption,is effective and safe in the treatment of patients with calcification defense.

[Objective]To evaluate the changes in cardiac structure and ventricular function in patients with Ander-son-Fabry Disease(AFD)by two-dimensional speckle tracking echocardiography(2D-STE)and to explore the character-istics of their early cardiac involvement.[Methods]All 45 patients diagnosed with AFD in this observational study under-went routine ultrasonic cardiogram(UCG)examination and 2D-STE.The patients were divided into 2 groups based on UCG measurements:with left ventricular hypertrophy(interventricular septum or posterior left ventricular wall thickness≥12 mm)and without left ventricular hypertrophy.TomTec software was used to analyze the echocardiographic images,then the baseline data,UCG routine parameters and myocardial strain of the two groups were compared.[Results]The study in-cluded 27 males(60.0%)and 18 females(40.0%),with an average age of(32.33±16.11),17 cases(37.78%)with left ventricular hypertrophy and 28 cases(62.22%)without left ventricular hypertrophy.All patients had normal left ventricu-lar ejection fraction(LVEF)(>50%).Compared with those without left ventricular hypertrophy,patients with left ventric-ular hypertrophy had significantly more target organ involvement,significantly higher E/A and average E/E' ratios(P<0.05).No statistical difference was found in global and segmental longitudinal strain(LS),circumferential strain(CS)and radial strain(RS)of the endocardium and myocardium between the two groups(all P>0.05).There were lower abso-lute values of global and segmental LS and CS in the myocardium than in the endocardium(all P<0.05),and higher abso-lute values of LS and RS in the mid segment than in the basal and apical segments(all P<0.05).[Conclusions]There is no significant association between early systolic dysfunction and left ventricular wall thickness.2D-STE strain can be used to detect AFD in the early stage.Ventricular wall myocardium exhibits more serious involvement than endocardium and mid segment was less involved than the apical and basal segments.

Objective: To analyze the trends in disease burden of tuberculosis among children under 5 years of age in China from 1990 to 2021, so as to provide insights for future tuberculosis control measures among children in China. Methods: Based on the Global Burden of Disease (GBD) 2021 datasets, the incidence, prevalence, mortality and disability adjusted life year(DALY) of tuberculosis of children under 5 years of age in China and globally were collected from 1990 to 2021. The incidence, prevalence, mortality and DALY rate of tuberculosis were compared by genders and types. In addition,the annual percent change(APC) and the average annual percent change(AAPC) of children s tuberculosis burden in China and globally from 1990 to 2021 were calculated by using the Joinpoint regression model, and the changing trends were analyzed. Results: The numbers of incident, prevalent and dead tuberculosis cases were 9 700, 8 477 800 and 200 among children under 5 years of age in China in 2021, and the DALY due to tuberculosis were 27 100 person years. There were significant reductions in incidence, prevalence, mortality and DALY rate of tuberculosis among children under 5 years of age in China ( AAPC =-5.45%, -1.14%, -12.37%, -11.34 %) and globally( AAPC =-2.38%, -1.41%, -4.66%, -4.56%), and the reductions in the incidence, mortality and DALY rate were more significant in China than globally ( P <0.05).In 1992 and later, the numbers of incident, prevalent and dead tuberculosis cases and the DALY of tuberculosis were higher among male than among female. In addition, the disease burden of drug susceptible tuberculosis appeared a tendency of downward in China from 1990 to 2021, while the incidence and prevalence of extensively drug resistant tuberculosis rose since 2015. Conclusions The disease burden of tuberculosis remarkably reduced among children under 5 years of age in China from 1990 to 2021. However, the burden of disease due to multidrug resistant tuberculosis appeared an upward trend recently. Increased attention is required to be paid to the prevention and control of tuberculosis among children and improved diagnosis and treatment of drug resistant tuberculosis are recommended.

Although significant progress has been made in the development of novel targeted drugs for the treatment of acute myeloid leukemia(AML)in recent years,chemotherapy still remains the mainstay of treatment and the overall survival is poor in most patients.Here,we demonstrated the antileukemia activity of a novel small molecular compound NL101,which is formed through the modification on bendamustine with a suberanilohydroxamic acid(SAHA)radical.NL101 suppresses the proliferation of myeloid malignancy cells and primary AML cells.It induces DNA damage and caspase 3-mediated apoptosis.A genome-wide clustered regularly interspaced short palindromic repeats(CRISPR)library screen revealed that phosphatase and tensin homologous(PTEN)gene is critical for the regulation of cell survival upon NL101 treatment.The knockout or inhibition of PTEN significantly reduced NL101-induced apoptosis in AML and myelodysplastic syndrome(MDS)cells,accompanied by the activation of protein kinase B(AKT)signaling pathway.The inhibition of mammalian target of rapamycin(mTOR)by rapamycin enhanced the sensitivity of AML cells to NL101-induced cell death.These findings uncover PTEN protein expression as a major determinant of chemosensitivity to NL101 and provide a novel strategy to treat AML with the combination of NL101 and rapamycin.
