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.

To understand the progress of, summarize the lessons learned from and analyze the challenges in the national schistosomiasis elimination program of China in 2024, this article presented the endemic situation of schistosomiasis and national schistosomiasis surveillance results in the People’s Republic of China in 2024. By the end of 2024, Shanghai Municipality, Zhejiang Province, Fujian Province, Guangdong Province and Guangxi Zhuang Autonomous Region continued to consolidate schistosomiasis elimination achievements, and 7 provinces of Jiangsu, Sichuan, Yunnan, Hubei, Hunan, Anhui and Jiangxi maintained the criteria of schistosomiasis transmission interruption. A total of 450 counties (cites, districts) were found to be endemic for schistosomiasis in China in 2024, including 26 061 endemic villages covering 73 630 500 residents at risk of infections. Among the 450 counties (cities, districts) endemic for schistosomiasis, 388 (86.22%) achieved the criteria of schistosomiasis elimination and 62 (13.78%) achieved the criteria of transmission interruption. In 2024, a total of 4 102 624 individuals received immunological tests for schistosomiasis in China, with 44 823 sero-positives identified (1.09% seroprevalence), and a total of 169 722 individuals received parasitological examinations, with 1 egg-positives detected. A total of 27 321 cases with advanced schistosomiasis were documented in China by the end of 2024. In 2024, a total of 575 686 bovines were raised in schistosomiasis-endemic villages of China, and 113 842 bovines received immunological tests, with 235 sero-positives detected (0.21% seroprevalence), while no egg-positives were identified among the 167 475 bovines receiving parasitological examinations. In 2024, snail survey was performed covering an area of 680 498.27 hm² in China, and 190 778.66 hm² snail habitats were identified, including 59.09 hm² emerging snail habitats and 704.23 hm² reemerging snail habitats. In 2024, a total of 19 665 schistosomiasis patients receiving chemotherapy with praziquantel in China, and expanded chemotherapy was given to humans at 571 722 person-times and to bovines at 306 740 herd-times. In addition, snail control with chemical treatment covered 117 111.37 hm² snail habitats across China in 2024, and the actual area of chemical treatment was 66 562.95 hm², while environmental improvements were performed in snail habitats covering an area of 1 374.26 hm². The national schistosomiasis surveillance results showed that the mean prevalence rates of Schistosoma japonicum infections were both 0 among humans and bovines in China in 2024, and no S. japonicum infection was detected in snails. These data demonstrated that the prevalence of schistosomiasis remained at a low level in China in 2024; however, the areas of snail habitats remained high and the number of fenced cattle showed a slight increase. To address these risks, it is imperative to maintain the integrated strategy with an emphasis on management of the source of S. japonicum infection and intensified snail control in high-risk areas, and to reinforce schistosomiasis surveillance and forecast and snail control in high-risk areas.

Objective To investigate the association between the Chinese visceral adiposity index (CVAI) and diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension among elderly people in Hebei Province. Methods In 2020, a stratified multi-stage random sampling was used to conduct questionnaire survey, physical examination and laboratory detection among permanent residents of 10 monitoring sites in Hebei Province. Logistic regression was used to analyze the association between CVAI and diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension. The area under the ROC curve (AUC) was used to evaluate the predictive value of CVAI for diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension. Results The detection rates of diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension were 19.8%, 74.6%, 78.2%, and 16.2%, respectively. Multivariate logistic regression analysis showed that compared with the lowest quartile of CVAI group Q1, the OR (95% CI) of diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension in the highest quartile Q4 group were 3.55 (2.58~4.89), 2.52 (1.92~3.31), 3.09 (2.31~4.12), and 4.92 (3.40~7.12), respectively. The ROC curve results showed that CVAI had the best predictive value in the diagnosis of diabetes with hypertension, and the optimized critical values in males and females were 128.54 and 141.88, respectively. Conclusion The detection rates of diabetes mellitus and hypertension are high in the elderly population in Hebei Province. CVAI is positively associated with the risk of diabetes mellitus, hypertension, diabetes mellitus or hypertension, and diabetes with hypertension among the elderly in Hebei. CVAI has the strongest prediction ability for diabetes with hypertension.

The host-microbe co-metabolism system, generating diverse exogenous and endogenous bioactive molecules that influence the host's immune and metabolic functions, plays a crucial role in the pathogenesis of atherosclerosis. Recent studies have elucidated the interaction between natural medicines and this co-metabolism system. Upon oral administration, natural medicine ingredients can undergo transformation by gut microbiota, potentially enhancing their bioavailability or anti-atherogenic efficacy. Furthermore, natural medicines can exert anti-atherogenic effects via modulation of endogenous host-microbe co-metabolism. This review presents an updated understanding of the dual association between natural medicines and host-microbe co-metabolites. It explores the critical function of microbial exogenous metabolites derived from natural medicines and uncovers the mechanisms underlying natural medicines' intervention on key nodes of endogenous host-microbe co-metabolism. These insights may offer new perspectives for cardiovascular disease (CVD) treatment and guide future drug discovery efforts.

To understand the progress of national schistosomiasis elimination program of China in 2023 and summarize the lessons and experiences, data on the endemic status of schistosomiasis and national schistosomiasis surveillance results in the People’s Republic of China were collected and analyzed at a national level. By the end of 2023, Shanghai Municipality, Zhejiang Province, Fujian Province, Guangdong Province and Guangxi Zhuang Autonomous Region continued to consolidate the achievements of schistosomiasis elimination, and Sichuan and Jiangsu provinces maintained the criteria of transmission interruption, while Yunnan and Hubei provinces were identified to achieve the criteria of transmission interruption in 2020, and Anhui, Jiangxi and Hunan provinces achieved the criteria of transmission interruption in 2023. A total of 451 counties (cites, districts) were found to be endemic for schistosomiasis in China in 2023, including 26 250 endemic villages covering 73 034 500 residents at risk of infections. Among the 451 endemic counties (cities, districts), 78.49% (354/451) achieved the criteria of schistosomiasis elimination and 21.51% (97/451) achieved the criteria of transmission interruption, respectively. In 2023, a total of 4 216 643 individuals received immunological tests, with 47 794 sero-positives identified, and a total of 184 216 individuals received parasitological examinations, with 4 egg-positives detected. A total of 27 768 cases with advanced schistosomiasis were documented in China by the end of 2023. In 2023, 539 548 bovines were raised in schistosomiasis-endemic areas of China, and 125 440 bovines received immunological tests, with 124 sero-positives detected, while no egg-positives were identified among the 133 508 bovines receiving parasitological examinations. In 2023, snail survey was performed at an area of 641 339.53 hm² and 184 819.77 hm² snail habitats were identified, including 51.53 hm² emerging snail habitats and 642.25 hm² reemerging snail habitats. In 2023, there were 20 198 schistosomiasis patients receiving praziquantel chemotherapy, and 598 183 person-time individuals and 283 954 herdtime bovines were given expanded chemotherapy. In 2023, snail control with chemical treatment was performed in 116 347.95 hm² snail habitats, and the actual area of chemical treatment was 65 690.89 hm², while environmental improvements were performed in snail habitats covering an area of 1 334.62 hm². The national schistosomiasis surveillance results showed that the mean prevalence of Schistosoma japonicum infections were both zero among humans and bovines in 2023, and no S. japonicum infection was detected in snails. These data demonstrated that transmission interruption of schistosomiasis had been achieved across all endemic provinces in China in 2023, and the endemic status of schistosomiasis tended to be stable, while advanced cases were predominant among all schistosomiasis cases. However, the areas of snail habitats remained high and cattle re-raising was very common in some regions. Intensified schistosomiasis surveillance and forecast and snail control in high-risk areas are needed.

Objective:To evaluate the effect of sleep deprivation on the expression of sirtuin 6 (SIRT6) in the cerebellum of immature mice.Methods:Fifty SPF healthy male C57BL/6 mice, aged 4 weeks, weighing 14-16 g, were divided into 2 groups ( n=25 each) using a random number table method: control group (Con group) and sleep deprivation group (SD group). The chronic sleep deprivation model was prepared by using the multi-platform water environment method, with 20 h of sleep deprivation per day for 10 consecutive days. After sleep deprivation, a balance beam experiment was performed to test the balance and coordination ability of mice. The mice were sacrificed after anesthesia and cerebellar lobular IV-VI (4-6 cb) tissues were taken for microscopic examination of the ultrastructure (with a transmission electron microscope) and for determination of the dendritic spine density of cerebellar 4-6cb Purkinje neurons (by Golgi staining), co-expression of SIRT6 and Calbindin D-28k (CbD-28k) and expression of glucose transporter Glut3 of cerebellar 4-6cb (by immunofluorescence staining). Results:Compared with group Con, the duration of passage through the balance beam was significantly prolonged, and the number of posterior foot slips was increased, the synaptic gap of cerebellar 4-6cb neurons was increased, the thickness of postsynaptic density was increased, the density of dendritic spines of Purkinje cells and the number of positive cells co-expressing SIRT6 and CbD-28k were decreased, and the expression of Glut3 was down-regulated in group SD ( P<0.05). Conclusions:The mechanism by which sleep deprivation decreases the abilities of balance and coordination is related to down-regulating SIRT6 expression in cerebellar Purkinje cells and decreasing neuronal glucose metabolism, thus damaging the synaptic plasticity of cerebellum in immature mice.

Idiopathic pulmonary fibrosis (IPF) is an interstitial lung disease that is difficult to diagnose clinically, and finding appropriate biomarkers to assist in the diagnosis and prognosis monitoring of IPF can improve the proportion of early diagnosis and timely treatment of these patients and improve the quality of life of patients

Objective:The combined diagnosis models was constructed with the test indicators and its application value in the clinical evaluation of patients with interstitial lung disease was evaluated.Methods:Methodology development and validation. A total of 101 patients with idiopathic pulmonary fibrosis (IPF) and 107 patients with non-IPF interstitial lung disease admitted to China-Japan Friendship Hospital from 2022 to 2023 were collected, and 98 healthy people were collected during the same period. The population in each group was divided into modeling group (180 cases) and validation group (126 cases) by complete randomization. Serum samples and clinical test results were collected. The test indicators included white blood cell count, lymphocyte count, monocyte count, hemoglobin concentration, highly sensitive C-reactive protein, Krebs von den Lungen 6, total cholesterol, triglycerides, high density lipoprotein cholesterol, low density lipoprotein cholesterol, adenosine deaminase, neuron-specific enolase, alpha-fetoprotein, carcinoembryonic antigen, cytokeratin 19 fragment, carbohydrate antigen 15-3, gastrin releasing peptide precursor, squamous cell carcinoma antigen and interleukin 1 (IL-1), IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12p70, IL-17, tumor necrosis factor-α, interferon-α, interferon-γ. Multiple collinearity test, univariate and multivariate logistic regression were performed for the included test indicators in each group, and nomograms were established and validated by receiver operating characteristic (ROC) curves, calibration curves and clinical decision curves.Results:By comparing interstitial lung disease to healthy people, carbohydrate antigen 15-3 ( OR=1.285, 95% CI 1.178-1.402), IL-6 ( OR=1.128, 95% CI 1.011-1.258), adenosine deaminase ( OR=1.465, 95% CI 1.261-1.702), and Krebs von den Lungen-6 ( OR=1.013, 95% CI 1.008-1.017) were independent risk factors for interstitial lung disease. Based on these four indexes, the nomogram model was constructed. The AUCs of the combined diagnosis model in the modeling group and validation group were 0.967(95%CI 0.941-0.993)and 0.948(95% CI 0.911-0.984), respectively.Decision curve analysis showed that the net benefit of the combined diagnosis model in diagnosing IPF was higher than that of a single indicator within the threshold range of 0.01-1. In the comparison of IPF and non-IPF interstitial lung disease, alpha-fetoprotein ( OR=1.403, 95% CI 0.975-2.019) and squamous cell carcinoma antigen ( OR=0.531, 95% CI 0.321-0.878) were independent risk factors for IPF. The AUCs of the combined diagnosis model in the modeling group and validation group were 0.703 (95% CI 0.597-0.81) and 0.642 (95% CI 0.528-0.757), respectively. Through calibration curve and clinical decision curve verification, it was found that it had a certain value in the differential diagnosis of IPF. Conclusions:Carbohydrate antigen 15-3, IL-6, adenosine deaminase and Krebs von den Lungen 6 are risk factors of interstitial lung disease, which can be used to construct a combined diagnostic model for the diagnosis of interstitial lung disease. Alpha-fetoprotein and squamous cell carcinoma antigen are risk factors of IPF, which can be used to construct a combined diagnostic model to distinguish IPF from non-IPF interstitial lung disease and assist clinical diagnosis of IPF.
