ObjectiveTo analyze the long-term trend of incidence and mortality of type 2 diabetic kidney disease (DKD) in China from 1990 to 2021. MethodsThe Joinpoint regression model was used to analyze the average annual percentage change (AAPC) of standardized incidence rate and standardized mortality rate, and the age-period-cohort (APC) model was constructed to analyze the longitudinal age change, period and cohort effect risk ratio (RR). ResultsFrom 1990 to 2021, the standardized incidence rate of type 2 DKD in males and females showed an overall upward trend, with AAPC of 0.08% and 0.36%, respectively. The age-standardized mortality rate of the total population and female showed a downward trend, with AAPC of -0.61% and -1.03%, respectively. However, there was no significant difference in males. APC model showed that the age effect existed: the peak age was 75-79 years old, the mortality rate of females increased, and the mortality rate of males decreased after 80-84 years old. For the effect of time period, the risk of type 2 DKD incidence in females in 2017—2021 was 1.05 times that in 2002—2006, and the risk of death in males and females in 2017—2021 was 0.84 and 0.71 times that in 2002—2006, respectively. For cohort effects, the highest risk of disease was seen in men and women born in 1967—1971, and the highest risk of death was seen in men born in 1952—1956 and women born in 1912—1916. ConclusionFrom 1990 to 2021, the standardized incidence rate of type 2 DKD in China shows an upward trend, and the standardized mortality rate shows a downward trend. It is necessary to strengthen the health behavior publicity and education of type 2 DKD, and actively carry out early screening to reduce the disease burden.

Objective To evaluate the effect of LifePort combined with polymyxin B in preventing donor-derived infections caused by preservation solution contamination. Methods Clinical data of 110 kidney transplant recipients were retrospectively analyzed. According to the decontamination status of preservation solution, the recipients were divided into the decontamination group (n=62) and the non-decontamination group (n=48). The general data of the two groups were compared, and the preventive effect of polymyxin B on possible donor-derived infections (p-DDI) was analyzed, especially infections associated with multidrug-resistant Gram-negative bacteria (MDR GNB). Results There were no statistically significant differences in baseline data (gender, age, preservation solution contamination status, etc.) between the decontamination group and the non-decontamination group (all P > 0.05). The overall contamination rate of preservation solution was 80.0%, and 68 contaminated samples were with single microorganism and 20 with multiple microorganisms. Coagulase-negative staphylococci, Enterococcus and Klebsiella pneumoniae were the most common microorganisms in the positive samples. Fifteen cases of preservation solution were contaminated by MDR GNB, including 10 cases in the non-decontamination group and 5 cases in the decontamination group, with no statistically significant difference between the two groups (P = 0.053). Postoperative infection-related events occurred in 69 recipients, including 39 cases in the non-decontamination group and 30 cases in the decontamination group, with the incidence rate in the non-decontamination group significantly higher than that in the decontamination group (P < 0.001). Only 10 cases of infections were identified as p-DDI, all of which were positive for preservation solution culture, including 8 cases in the non-decontamination group and 2 cases in the decontamination group (P < 0.05). There were 5 cases of p-DDI related to MDR GNB in the non-decontamination group, while no such cases occurred in the decontamination group (P < 0.05). No adverse reactions related to polymyxin B were observed, and no recipient death or renal allograft dysfunction occurred in either group. Conclusions Adding polymyxin B to the preservation fluid during hypothermic machine perfusion with LifePort before renal transplantation may reduce p-DDI and its potential adverse consequences.

Objective To explore the association between dynamic indexes of maternal progesterone in early pregnancy and the average level and growth rate of fetal head circumference(HC)in mid-and late pregnancy.Methods This study adopted a retrospective cohort design and included 255 singleton pregnant women in the maternal and infant cohort of The First Affiliated Hospital of Xi'an Jiaotong University from January 2015 to December 2024.The progesterone levels of their early venous blood were detected and divided into two groups of progesterone trajectories,namely,fluctuating type and increasing type,by morphology.The dynamic indicators of progesterone in early pregnancy were constructed:cumulative dynamic deviation index in the first trimester(CDDI-P1T),gestational age at progesterone peak(GA-PP),and maximal relative progesterone decline in the first trimester(MRD-P1T).The average head circumference level and linear growth rate of the fetuses in the middle and late pregnancy were calculated.Generalized linear regression(GLM)was used to analyze the linear association between progesterone dynamic indicators and head circumference development.The key gestational weeks of progesterone affecting fetal head development were explored by linear regression of gestational weeks.Ordinary least squares(OLS)regression and restricted cubic spline(RCS)plots were used to draw the nonlinear association between progesterone dynamic indicators and head circumference.Results Among the 255 pregnant women included,92.5%of the progesterone trajectories in early pregnancy were fluctuating,and 7.5%were increasing.The growth rates of the increasing progesterone trajectory group were higher in the second and third trimesters than in the fluctuating group,but the differences were not statistically significant(all P>0.05).GLM analysis showed that for every 1 unit increase in CDDI-P1T,the head circumference in the middle and late pregnancy increased significantly by 1.574 cm and 1.193 cm(Z=3.714,2.885,P<0.01).The delay of GA-PP was negatively correlated with the head circumference in the middle pregnancy(β=-0.190 cm,95%CI:-0.339--0.041,P=0.010)but positively correlated with the head circumference growth rate in the late pregnancy(β=0.022 cm/week,95%CI:0.003-0.041,P=0.025).A 10%decrease in the decline of CDDI-P1T increased the head circumference in the middle pregnancy by 0.200 cm(95%CI:0.016-0.384,P=0.033),and a 100%decrease in the decline increased the head circumference growth rate in the late pregnancy by 0.201 cm/week(95%CI:0.002-0.399,P=0.048).The analysis of the key time window showed that for every 20 nmol/L increase in progesterone during 9.5-13 weeks of pregnancy,the mid-term head circumference increased by 0.035-0.166 cm(Z=2.452-3.517,allP<0.05),and the late-term head circumference increased by 0.767 cm during 9-13 weeks of pregnancy(Z=2.452-3.517,all P<0.05).When progesterone increased during 9.5-10.5 weeks of pregnancy,the growth rate of mid-term head circumference increased by 0.013-0.023 cm/week(Z=2.074-2.243,all P<0.01).When progesterone increased during 8.5-10.5 weeks of pregnancy,the growth rate of late-term head circumference increased by 0.010-0.026 cm/week(Z=2.061-3.137,all P<0.05).Conclusion Progesterone dynamic index is a new sensitive tool for evaluating fetal head circumference development.There is a stage-specific window period for progesterone regulation.9.5-13 weeks of pregnancy is the critical period for progesterone to affect head circumference growth,and 9.5-10.5 weeks of pregnancy is the core window for regulating the growth rate of head circumference.Therefore,it is necessary to combine progesterone dynamic index and time window for individualized intervention to promote the transformation of prenatal care from pregnancy maintenance to eugenics intervention.

Objective:To investigate the disease self-management status of patients with chronic obstructive pulmonary disease (COPD) and its influential factors, providing evidence for the development of effective management strategies.Methods:A total of 483 patients with chronic obstructive pulmonary disease (COPD) who received treatment at Wenshan People's Hospital from April 2023 to April 2024 were included in this study. Their disease self-management status was assessed, and one-way analysis of variance and multiple linear regression analysis were conducted to identify the factors influencing patients' self-management abilities.Results:Among the 483 patients studied, only 2.9% (14/483) showed a complete understanding of their disease, while 21.12% (102/483) had some understanding of how to manage it. Only 34.38% (166/483) of the patients used inhalants outside the hospital as required, of which only 40.96% (68/166) used them regularly as required by doctors, and 60.84% (101/106) of the patients inhaled correctly. One-way analysis of variance and multiple linear regression analysis results showed that the factors affecting patients' self-management included COPD classification, smoking, life satisfaction, disease self-cognition, exercise habits, lung function, and gender ( t = 2.35, -2.22, -5.76, 4.37, -2.22, 5.09, -3.64, all P < 0.05). Conclusions:Patients with COPD exhibit poor disease self-management awareness and medication compliance. Patient's ability to self-manage their disease is associated with COPD classification, lung function, smoking, exercise habits, gender, life satisfaction, and disease self-cognition. Therefore, it is essential to develop appropriate intervention measures based on these factors, focusing on enhancing patients' self-management awareness and abilities to improve their quality of life.

The mechanism of action of traditional Chinese medicine (TCM) remains unclear. Historically, research on TCM has mainly focused on exploring the mechanisms of active components acting on single targets. However, it is insufficient to explain the complex mechanisms by which these active components in TCM treat diseases. In recent years, the emergence of molecular glues (MGs) theory has provided new strategies to address this issue. MGs are small molecules that can promote interactions between proteins at their interface. The characteristic of MGs is to establish connections between diverse protein structures, thereby enabling a chemically-mediated proximity effect that triggers a wide spectrum of biological functions. Natural products are the result of billions of years of evolutionary processes in the natural environment. Thus, the extensive structural diversity of natural products renders them a rich source of MGs, including polyketides, terpenoids, steroids, lignans, organic acids, alkaloids and other classes. Currently, several well-known natural MGs, including the immunosuppressants cyclosporin A (CsA) and tacrolimus (FK506), as well as the anticancer agent taxol, have been incorporated into clinical practice. Meanwhile, the advancement of new technologies is propelling the discovery of novel MGs from natural products. Thus, we primarily summarize a growing variety of MGs from natural origins reported in recent years and categorize them based on the chemical structural types. Moreover, the main sources of TCM are natural products. The discovery of natural MGs promises to provide a new perspective for the elucidation of the molecular mechanism behind the efficiency of TCM. In summary, this review aims to provide insights from the perspective of natural products that could potentially influence TCM and modern drug development.

Network pharmacology and molecular docking were employed to predict the mechanism of Zhizhu Decoction in regulating macrophage polarization to reduce adipose tissue inflammation in obese children, and animal experiments were then carried out to validate the prediction results. The active ingredients and targets of Zhizhu Decoction were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP). The inflammation related targets in the adipose tissue of obese children were searched against GeneCards, OMIM, and DisGeNET, and a drug-disease-target network was established. STRING was used to construct a protein-protein interaction(PPI) network and screen for core targets. R language was used to carry out Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analyses. AutoDock was used for the molecular docking between core targets and active ingredients. 24 SPF grade 6-week C57B/6J male mice were adaptively fed for 1 week, and 8 mice were randomly selected as the blank group. The remaining 16 mice were fed with high-fat diet for 8 weeks to onstruct a high-fat diet induced mouse obesity model. After successful modeling, the 16 mice were randomly divided into model group and Zhizhu Decoction group, with 8 mice in each group. Zhizhu Decoction group was intervened by gavage for 14 days, once a day. Blank group and model group were given an equal amount of sterile double distilled water(ddH_2O) by gavage daily. After the last gavage, serum and inguinal adipose tissue were collected from mice for testing. The morphology of inguinal adipose tissue was observed by hematoxylin-eosin(HE) staining, the levels of inflammatory factors interleukin-6(IL-6) and tumor necrosis factor-α(TNF-α)were detected by enzyme-linked immunosorbent assay(ELISA), and the protein expression of macrophage marker molecule nitric oxide synthase(iNOS) and epidermal growth factor like hormone receptor 1(F4/80) was detected by immunofluorescence staining. Network pharmacology predicted luteolin, naringenin, and nobiletin as the main active ingredients in Zhizhu Decoction and 15 core targets. KEGG pathway enrichment analysis revealed involvement in the key signaling pathway of nuclear factor κB(NF-κB). Molecular docking showed that the active ingredients of Zhizhu Decoction bound well to the core targets. Animal experiment showed that compared with the model group, Zhizhu Decoction reduced the distribution of inflammatory cytokines in the inguinal adipose tissue of mice, lowered the levels of TNF-α and IL-6 in the serum(P<0.05, P<0.01), and down-regulated the expression of iNOS and F4/80(P<0.05). The results showed that the active ingredients in Zhizhu Decoction, such as luteolin, naringenin, and nobiletin, inhibit the aggregation of macrophages in adipose tissue, downregulate their classic activated macrophage(M1) polarization, reduce the expression of inflammatory factors IL-6 and TNF-α, and thus improve adipose tissue inflammation in obese mice.
