ObjectiveTo observe the effects of Danggui Shaoyaosan on macrophage polarization and renal inflammation in db/db mice with diabetic kidney disease （DKD）， and to explore its renal protective effects and underlying mechanisms. MethodsEight db/m mice were assigned to the normal group， and forty db/db mice were randomly divided into a model group， low-， medium-， and high-dose Danggui Shaoyaosan groups （8.39， 16.77， 33.54 g·kg^-1）， and an irbesartan group （0.025 g·kg^-1）. All mice were administered treatment by gavage for 12 consecutive weeks. General conditions of the mice were observed during the intervention. At the end of the 12-week intervention， 24-h urine samples were collected using metabolic cages， after which the mice were anesthetized for sample collection. Blood was collected by enucleation and centrifuged to obtain serum for the determination of glycated serum protein （GSP）， serum creatinine （SCr）， blood urea nitrogen （BUN）， total cholesterol （TC）， and triglycerides （TG）. The urinary albumin-to-creatinine ratio （UACR） was measured. Renal pathological changes were observed using hematoxylin-eosin （HE） staining， periodic acid-Schiff （PAS） staining， and Masson staining. Enzyme-linked immunosorbent assay （ELISA） was used to detect serum tumor necrosis factor-α （TNF-α）， interleukin-10 （IL-10）， and monocyte chemoattractant protein-1 （MCP-1） levels. Immunofluorescence （IF） was performed to detect F4/80 expression in renal tissue， and immunohistochemistry （IHC） was used to assess CD206 expression. Real-time quantitative polymerase chain reaction （Real-time PCR） was employed to measure the mRNA expression of TNF-α， IL-10， inducible nitric oxide synthase （iNOS）， and arginase-1 （Arg-1）. Western blot analysis was used to detect the protein expression of iNOS， Arg-1， CD86， and CD206 in renal tissue. ResultsCompared with the normal group， the model group showed increased levels of GSP， UACR， SCr， BUN， TC， and TG， elevated levels of the inflammatory factor TNF-α and the chemokine MCP-1， and decreased IL-10 levels （P<0.01）. Pathological examination revealed glomerular hypertrophy， mesangial cell proliferation with marked mesangial expansion， inflammatory cell infiltration， vacuolar degeneration of renal tubular epithelial cells， prominent glycogen deposition， and increased collagen fiber deposition. In addition， relative F4/80 fluorescence intensity was enhanced， CD206 expression in the glomeruli and renal interstitium was reduced， and TNF-α and iNOS mRNA expression was increased. IL-10 and Arg-1 mRNA expression was decreased， iNOS and CD86 protein expression was increased， and Arg-1 and CD206 protein expression was decreased （P<0.05， P<0.01）. Compared with the model group， the Danggui Shaoyaosan groups and the irbesartan group showed decreased levels of GSP， UACR， SCr， BUN， TC， and TG， reduced serum TNF-α and MCP-1 levels， and increased IL-10 levels. Renal pathological damage was improved to varying degrees. Relative F4/80 fluorescence intensity was reduced， CD206 expression in the glomeruli and renal interstitium was increased， and TNF-α and iNOS mRNA expression was decreased. IL-10 and Arg-1 mRNA expression was increased， iNOS and CD86 protein expression was reduced， and Arg-1 and CD206 protein expression was increased （P<0.05， P<0.01）. ConclusionDanggui Shaoyaosan can improve renal function and alleviate renal pathological damage in db/db mice. Its mechanism may be related to inhibiting M1 pro-inflammatory macrophage polarization， promoting M2 anti-inflammatory macrophage polarization， reducing inflammatory responses， delaying the progression of renal fibrosis， improving renal pathological injury， and thereby exerting renal protective effects.

Objective:The aim of this study was to present an institution's experience with cochlear reimplantation（CRI）, to assess surgical challenges and post-operative outcomes and to increase the success rate of CRI. Methods:We retrospectively evaluated data from 76 reimplantation cases treated in a tertiary center between 2001 and 2022. Clinical features include caused of CRI, type of failure, surgical issues, and auditory speech performance were analyzed. Categorical Auditory Performance （CAP） and Speech Intelligibility Rating （SIR） scores were used to evaluate pre-and post-CRI outcomes. Our center's consecutive cohort of 1 126 patients had seven patients, while 69 patients were from other cochlear implant centers. Device failure was the most common cause of CRI（68/76）, with the remaining cases including flap complications（3/76）, magnet displacement（3/76）, secondary meningitis（1/76）, and foreign bodies around the implant（1/76）. Postoperative auditory and speech outcome improved in 31.6%（24/76） of patients, remained unchanged in 63.2%（48/76）, and decreased in CAP and SIR scores in 5.2%（4/76） of patients. Postoperatively, the seven patients with cochlear ossification and fibrosis scored lower on the overall CAP and SIR scale than non-ossification individuals, which is a significant factor in surgical success rates and auditory-speech outcomes. Conclusion:CRI surgery is a challenging but relatively safe procedure, and most reimplanted patients experience favorable postoperative outcomes. Medical complications and intracochlear damage are the main causes of poor postoperative results. Therefore, minimally invasive CI has a positive significance for reducing the difficulty of CRI surgery and improving the CI performance.

Objective:To analyze the association between inflammation-related dietary patterns and the risk for cognitive impairment in older adults aged ≥65 years in longevity areas in China by using reduced rank regression (RRR) analysis.Methods:This study used cross-sectional data from the 2021 Healthy Aging and Biomarkers Cohort Study, including the information about study participants' demographic characteristics, lifestyles, daily life activities, and disease histories. Dietary intake was obtained by using a simplified food frequency questionnaire. Cognitive impairment was evaluated based on the Mini-Mental State Examination Scale combined with years of education. Fasting venous blood samples were collected to detect inflammatory markers, especially high-sensitivity C-reactive protein (hs-CRP) and the platelet-to-lymphocyte ratio (PLR). RRR analysis was used to obtain inflammation-related dietary patterns using hs-CRP and PLR as response variables. Multivariate logistic regression model was used to analyze the association between dietary pattern score and the risk for cognitive impairment. Restricted cubic spline was used to explore the dose response relationship, and mediation analysis was used to quantify the mediating effects of hs-CRP and PLR.Results:Two dietary patterns were identified with RRR. The primary pattern was characterized by higher intakes of flour, red meat, and dairy products, and lower intake of fresh vegetables, explaining 6.84% of the variance in food intake and 0.50% of the variance in inflammatory markers. Compared with the T1 group, the T3 group had significantly higher risk for cognitive impairment ( OR=1.242, 95% CI: 1.034-1.491). Each one standard deviation increase in the dietary pattern score was associated with an 8.7% increase in the risk for cognitive impairment ( OR=1.087, 95% CI: 1.008-1.172), with a significant linear trend (overall-model P<0.001, non-linear P=0.295). Mediation analysis indicated that hs-CRP mediated 6.2% of the association between the dietary pattern and the risk for cognitive impairment. Conclusion:The inflammation- related dietary pattern characterized by higher consumption of flour, red meat, and dairy products and lower consumption of fresh vegetables is associated with an increased risk for cognitive impairment in older adults, and hs-CRP partially mediates this association.

This study aims to describe the population and regional distribution characteristics of smoking behavior among adult twins in the China Twin Registry (CNTR), as well as the concordance rates for smoking behavior in monozygotic and dizygotic twins, and estimate the heritability. The study population included adult twins in CNTR who had smoking questionnaire data. A random-effects regression model was used to describe the distribution of smoking behavior among different subgroups based on various characteristics. The concordance of smoking behavior between different zygosity groups was calculated, and heritability was estimated. A total of 28 444 twin pairs were included in this study, with an average age of (36.6±12.0) years. Among male twins, 41.2% were current smokers, while only 1.2% of females smoked. Higher smoking rates were observed among male smokers in the 50-59 age group ( z=23.0, P<0.001), northern regions ( z=2.9, P<0.01), rural areas ( z=-5.2, P<0.001), those who were divorced/widowed ( z=3.8, P<0.001), and first-born twins ( z=-4.3, P<0.001), while lower smoking rates were found in those with higher education ( z=-16.1, P<0.001) and unmarried individuals ( z=-16.0, P<0.001). The smoking concordance rate for male monozygotic twins was 69.6%, significantly higher than the 57.3% concordance rate for dizygotic twins ( χ 2=105.0, P<0.05). The heritability of smoking behavior in male twins was estimated at 28.9% (95% CI: 24.3%-33.4%). Stratified analyses showed differences in heritability across regions and age groups: the heritability in northern regions was 32.6% (95% CI: 27.3%-38.0%), higher than the 21.0% (95% CI: 12.4%-29.5%) observed in southern regions; the highest heritability of 35.1% (95% CI: 26.3%-43.9%) was found in the 18-29 age group, with heritability decreasing with age. In conclusion, the smoking rate and influencing factors in the twin population are similar to those in the general population, with unique characteristics, such as higher smoking rates in first-born twins. Genetic factors have a significant impact on smoking behavior.

Objective:To describe the distribution characteristics of alcohol consumption in adult twins in the Chinese National Twin Registry (CNTR), and further explore the influence of genetic factors on alcohol consumption in adult twins.Methods:The subjects of the study were twins registered by CNTR in 11 project areas across China from 2010 to 2018. A total of 56 966 twins (28 483 pairs) aged 18 years and above who answered questions about drinking behavior were included, and the random effect model was used to describe the population and regional distribution characteristics of alcohol consumption. Intra-pair analysis was performed to calculate the concordance rate and heritability of their alcohol consumption.Results:The age of all subjects was (36.6±12.0) years, and current drinkers accounted for 16.6% (9 461/56 966) of all subjects. In men, those aged 50-59 years, those in northern China, those living in rural area, those with low education level and those with high BMI, the proportions of current drinkers were higher. After excluding 468 pairs of twins who had stopped alcohol use and 21 764 pairs of twins who had no drink or had small amount drink, an intra-pair analysis was conducted in 4 929 pairs of same-sex twins, and found that the concordance rate of alcohol consumption was 64.0% (2 059/3 215) in monozygotic twins, and 52.6% (902/1 714) in dizygotic twins, the difference was significant ( P<0.001), and the heritability of alcohol consumption was 24.1% (95% CI: 18.9%- 29.3%). The further stratified analysis found that in southern men, the heritability was highest in those aged 40-49 years (36.1%, 95% CI: 21.6%-50.7%), while in northern men, the heritability was highest in those aged 50-59 years (34.2%, 95% CI: 18.1%-50.3%). Conclusions:In adult twins in China, there were population and regional differences in the distribution of alcohol consumption behavior, and alcohol consumption was influenced by genetic factors, and gender, age and region had potential modifying effects.

Objective:To systematically evaluate the effect of the Dietary Approaches to Stop Hypertension (DASH) diet on common metabolic diseases.Methods:Following the PICOS framework to construct the search formula, we systematically searched the Web of science, PubMed, Cochrane Library, CNKI, Wanfang, and VIP databases for randomized controlled trials (RCTs) investigating the effect of the DASH diet on multiple metabolic indices including body weight, body mass index (BMI), fasting blood glucose, triglycerides, systolic blood pressure (SBP), and diastolic blood pressure (DBP) in patients with metabolic disorders (e.g., obesity, diabetes mellitus, and hypertension) published both in China and abroad from 1 January 2000 to 31 December 2023. The search terms were combinations of MeSH and free-text terms, and the raw data obtained from the search were screened according to the inclusion and exclusion criteria to determine the articles that were finally included in the analysis. The differences in these metabolic indices were compared between the intervention group group (using DASH diet) and the control group. The quality of the studies was assessed quantitatively using the modified Jadad scale and qualitatively using the Risk of Bias 2 (RoB 2) tool by two reviewers independently. Data analysis was conducted using Stata 18.0 software, with the I 2 test for heterogeneity evaluation and funnel plots for qualitative assessment of publication bias. Results:A total of 13 RCTs were included, involving 1 653 participants. Meta-analysis showed that the intervention group had more favorable effects on SBP ( SMD:-0.91, 95%CI: -1.55–-0.27; Z=-2.79, P<0.005) and DBP ( SMD: -0.98, 95%CI: -1.62–-0.33; Z=-2.96, P<0.05) than the control diet. Fasting blood glucose ( SMD: 0.21, 95% CI: 0.01–0.41; Z=2.06, P=0.04) was statistically significant. There were no significant differences in body weight, BMI, fasting blood glucose, and triglyceride outcomes betweeen these two groups. Conclusions:DASH diet is effective in controlling SBP and DBP in patients with metabolic disorders and may be useful in clinical adjunctive therapy. However, current evidence does not support an independent improvement in glycolipid metabolic markers.

Objective:To construct Nomogram prediction model for pulmonary infection in patients after aortic dissection surgery, so as to provide reference for early screening of high-risk groups and carrying out preventive nursing measures.Methods:This was a retrospective case-control study. The case data of patients after aortic dissection surgery in the Second Affiliated Hospital of Anhui Medical University from January 2020 to October 2023 were selected by convenient sampling method and divided into pulmonary infection group and non-pulmonary infection group according to whether pulmonary infection occurred within one week after surgery. The risk factors of pulmonary infection after aortic dissection surgery were analyzed by Logistic regression and the Nomogram prediction model was constructed by R4.3.3.The model was evaluated by area under the receiver operating characteristic curve, calibration curve and decision curve analysis.Results:A total of 324 patients with aortic dissection were collected, and the incidence of postoperative pulmonary infection was 26.9%(87/324). There were 87 cases in pulmonary infection group, including 65 males and 22 females, with a median age of 58.0 years. There were 237 cases in non-pulmonary infection group, including 180 males and 57 females, with a median age of 60.0 years. Finally, operation time ( OR=1.015, 95% CI 1.007-1.022), intraoperative blood transfusion ( OR=1.001, 95% CI 1.000-1.022), mechanical ventilation time ( OR=7.624, 95% CI 2.679-21.692), postoperative invasive operation ( OR=6.310, 95% CI 1.545-25.778) and postoperative renal insufficiency ( OR=6.723, 95% CI 1.219-37.063) were independent risk factors for pulmonary infection after aortic dissection surgery. The area under the receiver operating characteristic curve of the model was 0.978, sensitivity of 93.7%, and specificity of 90.8%. The calibration curve showed good consistency, and the decision curve analysis curve showed good net benefit. Conclusions:Operation time, intraoperative blood transfusion, mechanical ventilation time, postoperative invasive operation and postoperative renal insufficiency are high-risk factors of pulmonary infection after aortic dissection surgery and the constructed predictive model has predictive value.

Objective:To construct an early rehabilitation management model for postoperative kinesiophobia patients after total knee arthroplasty (TKA) based on a topic-oriented quality control circle method, aiming to improve the quality of early rehabilitation management.Methods:Using a convenience sampling method, 120 TKA patients with kinesiophobia treated in the Department of Orthopedics at the First Affiliated Hospital of Zhengzhou University from January to April 2022 and September to December 2022 were selected. The patients from January to April 2022 were set as the control group, and those from September to December 2022 were set as the observation group, with 60 patients in each group. The control group received routine rehabilitation management after TKA surgery, while the observation group received the early rehabilitation management model based on the 10 steps of the topic-oriented quality control circle (topic selection, activity planning, clarification of the topic, goal setting, countermeasure formulation, pursuit of optimal strategies, etc.) in addition to the routine management. The differences between the two groups were compared in terms of kinesiophobia score, knee function score, pain score, early rehabilitation assessment rate, effective analgesia rate, and 24-hour ambulation rate.Results:After the intervention, the observation group showed significantly lower knee pain scores (2.89±0.66) and kinesiophobia scores (23.27±4.87) compared to the control group, with a significantly higher knee function score (74.47±7.40), all differences were statistically significant (all P<0.01). Additionally, the observation group had a significantly higher early rehabilitation assessment rate, effective analgesia rate, 24-hour ambulation rate, early rehabilitation compliance rate, earlier time for the first ambulation, shorter hospital stay, and reduced costs compared to the control group, with all differences showing statistical significance (all P<0.01) . Conclusions:The application of the topic-oriented quality control circle to construct and implement an early rehabilitation management model for postoperative kinesiophobia patients after TKA can effectively improve the quality of early rehabilitation management, reduce kinesiophobia levels, enhance knee joint function, and alleviate the economic burden.
