BACKGROUND: Spatiotemporal disparities exist in the disease burden of non-communicable diseases (NCDs) attributable to kidney dysfunction, which has been poorly assessed. The present study aimed to evaluate the spatiotemporal trends of the global burden of NCDs attributable to kidney dysfunction and to predict future trends. METHODS: Data on NCDs attributable to kidney dysfunction, quantified using deaths and disability-adjusted life-years (DALYs), were extracted from the Global Burden of Diseases Injuries, and Risk Factors (GBD) Study in 2019. Estimated annual percentage change (EAPC) of age-standardized rate (ASR) was calculated with linear regression to assess the changing trend. Pearson's correlation analysis was used to determine the association between ASR and sociodemographic index (SDI) for 21 GBD regions. A Bayesian age-period-cohort (BAPC) model was used to predict future trends up to 2040. RESULTS: Between 1990 and 2019, the absolute number of deaths and DALYs from NCDs attributable to kidney dysfunction increased globally. The death cases increased from 1,571,720 (95% uncertainty interval [UI]: 1,344,420-1,805,598) in 1990 to 3,161,552 (95% UI: 2,723,363-3,623,814) in 2019 for both sexes combined. Both the ASR of death and DALYs increased in Andean Latin America, the Caribbean, Central Latin America, Southeast Asia, Oceania, and Southern Sub-Saharan Africa. In contrast, the age-standardized metrics decreased in the high-income Asia Pacific region. The relationship between SDI and ASR of death and DALYs was negatively correlated. The BAPC model indicated that there would be approximately 5,806,780 death cases and 119,013,659 DALY cases in 2040 that could be attributed to kidney dysfunction. Age-standardized death of cardiovascular diseases (CVDs) and CKD attributable to kidney dysfunction were predicted to decrease and increase from 2020 to 2040, respectively. CONCLUSION NCDs attributable to kidney dysfunction remain a major public health concern worldwide. Efforts are required to attenuate the death and disability burden, particularly in low and low-to-middle SDI regions.

Guided by the concept of quality by design(QbD), this study optimizes the calcination and quenching process of calcined Magnetitum and establishes the XRD characteristic spectra of calcined Magnetitum, providing a scientific basis for the formulation of quality standards. Based on the processing methods and quality requirements of Magnetitum in the Chinese Pharmacopoeia, the critical process parameters(CPPs) identified were calcination temperature, calcination time, particle size, laying thickness, and the number of vinegar quenching cycles. The critical quality attributes(CQAs) included Fe mass fraction, Fe~(2+) dissolution, and surface color. The weight coefficients were determined by combining Analytic Hierarchy Process(AHP) and the criteria importance though intercrieria correlation(CRITIC) method, and the calcination process was optimized using orthogonal experimentation. Surface color was selected as a CQA, and based on the principle of color value, the surface color of calcined Magnetitum was objectively quantified. The vinegar quenching process was then optimized to determine the best processing conditions. X-ray diffraction(XRD) was used to establish the characteristic spectra of calcined Magnetitum, and methods such as similarity evaluation, cluster analysis, and orthogonal partial least squares-discriminant analysis(OPLS-DA) were used to evaluate the quality of the spectra. The optimized calcined Magnetitum preparation process was found to be calcination at 750 ℃ for 1 h, with a laying thickness of 4 cm, a particle size of 0.4-0.8 cm, and one vinegar quenching cycle(Magnetitum-vinegar ratio 10∶3), which was stable and feasible. The XRD characteristic spectra analysis method, featuring 9 common peaks as fingerprint information, was established. The average correlation coefficient ranged from 0.839 5-0.988 1, and the average angle cosine ranged from 0.914 4 to 0.995 6, indicating good similarity. Cluster analysis results showed that Magnetitum and calcined Magnetitum could be grouped together, with similar compositions. OPLS-DA discriminant analysis identified three key characteristic peaks, with Fe_2O_3 being the distinguishing component between the two. The final optimized processing method is stable and feasible, and the XRD characteristic spectra of calcined Magnetitum was initially established, providing a reference for subsequent quality control and the formulation of quality standards for calcined Magnetitum.

Objective:To investigate the risk factors and establish a prediction model of primary non-response (PNR) to anti-tumor necrosis factor-α(TNF-α) monoclonal antibody in Crohn′s disease (CD) patients.Methods:From December 1, 2018 to July 31, 2022, 103 patients with CD treated with the anti-TNF-α monoclonal antibody in Renmin Hospital of Wuhan University were enrolled (modeling group), and at the same time, 109 patients with CD treated with anti-TNF-α monoclonal antibody in Zhongnan Hospital of Wuhan University were selected (validation group). The baseline clinical data of all the patients before the first treatment of anti-TNF-α monoclonal antibody were collected, which included C-reactive protein (CRP), the simplified Crohn′s disease activity index (CDAI), and modified multiplier simple endoscopic score for Crohn′s disease (MM-SES-CD), etc. Multivariate logistic regression was used to screen the independent risk factors of PNR in patients with CD treated with the anti-TNF-α monoclonal antibody, and to establish the nomograms prediction model. The area under the curve (AUC) of the receiver operating characteristic curve (ROC), the net reclassification index (NRI), integrated discrimination improvement index (IDI), and decision curve analysis (DCA) were used to evaluate the predictive efficacy and clinical application value of the prediction model. DeLong test was used for statistical analysis.Results:The results of multivariate logistic regression analysis showed that high level of CRP ( OR=1.030, 95% confidence interval (95% CI) 1.002 to 1.059), simplified CDAI ( OR=1.399, 95% CI 1.023 to 1.913), and MM-SES-CD ( OR=1.100, 95% CI 1.025 to 1.181) in baseline were independent risk factors of PNR in patients with CD treated with the anti-TNF-α monoclonal antibody ( P=0.033, 0.036 and 0.008). The results of ROC analysis showed that the AUCs of CRP, simplified CDAI, MM-SES-CD, and the prediction model in the modeling group and the validation group were 0.697(95% CI 0.573 to 0.821), 0.772(95% CI 0.666 to 0.879), 0.819(95% CI 0.725 to 0.912), 0.869 (95% CI 0.786 to 0.951) and 0.856 (95% CI 0.756 to 0.955), respectively. The AUC of the prediction model in the modeling group was greater than those of CRP and simplified CDAI, and the differences were statistically significant ( Z=3.00 and 2.75, P=0.003 and 0.006), while compared with MM-SES-CD and the validation group, the differences were not statistically significant (both P>0.05). However, compared with MM-SES-CD, the NRI and IDI of the prediction model in the modeling group were 0.205(95% CI 0.002 to 0.409, P=0.048) and 0.098(95% CI 0.022 to 0.174, P=0.011), respectively, suggesting that the predictive ability of the prediction model was better than that of MM-SES-CD. The results of DCA indicated that the prediction model had significant clinical benefits in both the modeling group and the validation group. Conclusions:A prediction model was successfully constructed based on the independent risk factors for PNR in patients with CD treated with the anti-TNF-α monoclonal antibody. After verification, the prediction model has good prediction performance and significant clinical benefits.

This study aims to explore the effect of preventive administration of Yigong Powder on the learning and memory abilities of the mouse model of aging induced by D-galactose and decipher the underlying mechanism, so as to provide a basis for the application of Yigong Powder in the prevention and treatment of cognitive decline. Forty KM mice were randomized into control, model, donepezil(1.5 mg·kg~(-1)), and high-dose(7.5 g·kg~(-1)) and low-dose(3.75 g·kg~(-1)) Yigong Powder groups. The mice in other groups except the control group were injected with D-galactose(200 g·kg~(-1)) at the back of the neck for the modeling of aging. At the same time, the mice were administrated with corresponding drugs by gavage for one month. Morris water maze was used to examine the learning and memory abilities of the mice. Hematoxylin-eosin staining was employed to observe the pathological and morphological changes of the hippocampus. The immunofluorescence assay was employed to detect the expression of ionized calcium-binding adapter molecule 1(IBA1), glial fibrillary acidic protein(GFAP), chemokine C-X-C-motif ligand 12(CXCL12), chemokine C-X-C-motif receptor 4(CXCR4) in the hippocampus and observe the positional relationship between IBA1, GFAP, and CXCR4. Western blot was employed to determine the protein levels of extracellular regulated kinase(ERK), p-ERK, and tumor necrosis factor receptor 1(TNFR1). Enzyme-linked immunosorbent assay was employed to measure the levels of glutamate and tumor necrosis factor(TNF-α) in the brain tissue and the level of TNF-α in the serum and spleen. Yigong Powder significantly shortened the escape latency, increased the times crossing platforms, and prolonged the cumulative time in quadrants of the aging mice. It alleviated the nerve cell disarrangement, increased intercellular space, and cell degeneration or death in the hippocampus and reduced the pathology score of the damaged nerve. Moreover, Yigong Powder reduced the positive area of IBA1 and GFAP, reduced the levels of TNF-α in the brain tissue, serum, and spleen, and decreased spleen index. Furthermore, Yigong Powder decreased the average fluorescence intensity of CXCL12 and CXCR4, reduced CXCR4-positive astrocytes and microglia, down-regulated the protein levels of p-ERK/ERK and TNFR1, and lowered the level of glutamate in the brain tissue. This study showed that the preventive administration of Yigong Powder can ameliorate the learning and memory decline of the D-galactose-induced aging mice by regulating the immune function of the spleen and the CXCL12/CXCR4 signaling in the brain to reduce glutamate release. However, the mechanism of Yigong San in preventing and treating dementia via regulating spleen and stomach function remains to be studied.

The ovary is the reproductive organ of female mammals, which is responsible for producing mature eggs and secreting sex hormones. The regulation of ovarian function involves the ordered activation and repression of genes related to cell growth and differentiation. In recent years, it has been found that histone posttranslational modification can affect DNA replication, damage repair and gene transcriptional activity. Some regulatory enzymes mediating histone modification are co-activators or co-inhibitors associated with transcription factors, which play important roles in the regulation of ovarian function and the development of ovary-related diseases. Therefore, this review outlines the dynamic patterns of common histone modifications (mainly acetylation and methylation) during the reproductive cycle and their regulation of gene expression for important molecular events, focusing on the mechanisms of follicle development and sex hormone secretion and function. For example, the specific dynamics of histone acetylation are important for the arrest and resumption of meiosis in oocytes, while histone (especially H3K4) methylation affects the maturation of oocytes by regulating their chromatin transcriptional activity and meiotic progression. Besides, histone acetylation or methylation can also promote the synthesis and secretion of steroid hormones before ovulation. Finally, the abnormal histone posttranslational modifications in the development of two common ovarian diseases (premature ovarian insufficiency and polycystic ovary syndrome) are briefly described. It will provide a reference basis for understanding the complex regulation mechanism of ovarian function and further exploring the potential therapeutic targets of related diseases.
