Diabetic kidney disease （DKD） is a kidney disease caused by hyperglycemia，which is one of the most common microvascular complications of diabetes. Due to the high incidence of diabetes，the incidence of DKD has also increased year by year，and DKD has become a global public health problem. The pathogenesis of DKD is related to mechanisms such as oxidative stress，inflammation，renal fibrosis，and decreased mitophagy activity，which are developed under a variety of complex mechanisms. In traditional Chinese medicine，it is believed that the incidence of DKD is closely related to damp heat. Therefore，it is necessary to grasp the treatment method of clearing heat and removing dampness in clinical medication. Huangkui Capsules （HKC） have the effect of clearing damp heat，detoxifying， and detumescence. Because of its unique curative effect on DKD，HKC is often used in the treatment of DKD. HKC plays a role in the treatment of DKD with a variety of pharmacokinetic and pharmacodynamic processes. In many laboratory studies，it has been found that the specific mechanisms of HKC in the treatment of DKD include increasing mitophagy，reducing mitochondrial damage，reducing renal fibrosis，controlling inflammatory response，and inhibiting oxidative stress，which can achieve the purpose of reducing renal damage and promoting renal function. Some clinical studies have also verified that the application of HKC alone can exert renal protective function through anti-inflammatory，anti-oxidative stress，anti-renal fibrosis effects，as well as reduction of urinary protein. Since DKD is not a single injury of renal function，it is often accompanied by problems in blood pressure，blood lipids，blood circulation，body immunity， and other aspects. Therefore，the combination of HKC with other drugs can often achieve more comprehensive results，improve the advantages of various drugs，and improve the therapeutic effect. The combination of drugs such as antihypertensive，lipid-lowering， vascular circulation improvement，immunity inhibition，and anti-oxidative stress with HKC has achieved good results. In addition，HKC is often used in combination with other Chinese patent medicines in clinics. The application of HKC in the treatment of DKD has made some progress，but there are still many places worthy of further study，and the research on the mechanism of HKC is not comprehensive enough. The research on its long-term effect and safety in clinical application is relatively lacking，and the drug variety is relatively single when combined with certain drugs. These problems deserve further attention. Finally，it is necessary to pay attention to the promotion and application of HKC in clinical practice so that HKC can be better applied in clinical practice and better solve practical problems for patients.

Objective To quantitatively assess the association of short-term exposure to polycyclic aromatic hydrocarbons (PAHs) in ambient fine particulate matter (PM2.5) with residents mortality. Methods A time-stratified case-crossover study was conducted from 2020 to 2022 among 10606 non-accidental residents by using the Guangzhou Cause of Death Surveillance System in Conghua District, Guangzhou. Exposure levels of PAHs in PM_2.5 and meteorological data during the study period were obtained from the Center for Disease Control and Prevention in Conghua District and the China Meteorological Administration Land Data Assimilation System (CLDAS-V2.0), respectively. Conditional Poisson regression model was used to estimate the exposure-response association between PAHs and the mortality risk. Results Fluoranthene, chrysene, benzo[k]fluoranthene, benzo[a]pyrene, and indeno[1,2,3-cd]pyrene were significantly associated with an increased risk of mortality. For every one interquartile range increase in exposure levels, the non-accidental mortality risks increased by 8.33% (95% CI: 1.80%, 15.27%), 4.67% (95% CI: 1.86%, 7.57%), 6.07% (95% CI: 2.08%, 10.21%), 4.62% (95% CI: 1.85%, 7.47%), and 4.70% (95% CI: 0.53%, 9.03%), respectively. The estimated non accidental deaths attributable to exposure to fluoranthene, chrysene, benzo[k]fluorine, benzo[a]pyrene and indine[1,2,3-cd]pyrene were 5.91%, 6.08%, 6.51%, 6.46%, and 4.21%, respectively. Conclusions Short-term exposure to PAHs in PM_2.5, including fluoranthene, chrysene, benzo[k]fluoranthene, benzo[a]pyrene and indine[1,2,3-cd]pyrene, was significantly associated with an increased risk of mortality among residents.

Alcoholic liver disease(ALD), a major cause of chronic liver disease worldwide, poses a serious threat to human health. Despite the availability of various drugs for treating ALD, their efficacy is often uncertain, necessitating the search for new therapeutic approaches. Traditional Chinese medicine polysaccharides have garnered increasing attention in recent years due to their versatility, high efficiency, and low side effects, and they have demonstrated significant potential in preventing and treating ALD. Emerging studies have suggested that these polysaccharides exert their therapeutic effects through multiple mechanisms, including the inhibition of oxidative stress and the regulation of lipid metabolism, gut microbiota, and programmed cell death. This review summarizes the recent research progress in the pharmacological effects and regulatory mechanisms of traditional Chinese medicine polysaccharides in treating ALD, aiming to provide a scientific basis and theoretical support for their application in the prevention and treatment of ALD.

Tailored lipid nanoparticles (LNPs)-mediated small interfering RNA (siRNA) nanomedicines show promise in treating liver disease, such as acute liver injury (ALI) and non-alcoholic steatohepatitis (NASH). However, constructing LNPs that address biosafety concerns, ensure efficient delivery, and target specific hepatic subcellular fractions has been challenging. To evade above obstacles, we develop three novel self-degradable "gemini-like" ionizable lipids (SS-MA, SS-DC, SS-MH) by incorporating disulfide bonds and modifying the length of ester bond and tertiary amino head. Our findings reveal that the disulfide-bond-bridged LNPs exhibit reduction-responsive drug release, improving both biosafety and siRNA delivery efficiency. Furthermore, the distance of ester bond and tertiary amino head significantly influences the LNPs' pK _a, thereby affecting endosomal escape, hemolytic efficiency, absorption capacity of ApoE, uptake efficiency of hepatocytes and liver accumulation. We also develop the modified-mannose LNPs (M-LNP) to target liver macrophages specifically. The optimized M-MH_LNP@TNFα exhibits potential in preventing ALI by decreasing tumor necrosis factor α (TNFα) levels in the macrophages, while MH_LNP@DGAT2 could treat NASH by selectively degrading diacylglycerol O-acyltransferase 2 (DGAT2) in the hepatocytes. Our findings provide new insights into developing novel highly effective and low-toxic "gemini-like" ionizable lipids for constructing LNPs, potentially achieving more effective treatment for hepatic diseases.

Background Exposure to air pollutants increases the risk of diseases in multiple systems, including respiratory and cardiovascular systems, yet its association with neurological diseases remains unclear. Objective To quantitatively evaluate the association between short-term exposure to air pollutants and outpatient and emergency visits for neurological diseases, identify potential susceptible populations, and quantify associated disease burden. Methods Daily 24-hour average concentrations of fine particulate matter (PM_2.5), inhalable particulate matter (PM₁₀), sulfur dioxide (SO₂), nitrogen dioxide (NO₂), and carbon monoxide (CO), daily maximum 8-hour average concentration of ozone (O₃), daily meteorological data (24-hour average temperature, 24-hour average relative humidity), and data on daily outpatient and emergency department visits for neurological diseases from two hospitals in Conghua District, Guangzhou, China, were collected from 2015 to 2022. A time-stratified case-crossover design was adopted, and a conditional Poisson regression model was constructed to analyze the association between air pollution exposure and neurological disease visits. Two-pollutant models and sensitivity analysis were used to validate model stability. Stratified analyses by season (cold season: from November to March; warm season: from April to October), sex (male, female), and age (≤45 years, 46–60 years, ≥61 years) were performed to identify vulnerable group. Additionally, the number and proportion of neurological disease visits attributable to short-term air pollutant exposure were calculated. Results A total of 72 673 outpatient and emergency department visits for neurological diseases were included during the study period. Most of the patients were middle-aged and elderly individuals (69.89% were over 45 years old) and females (60.25%). The results of single-pollutant models showed that for each interquartile range (IQR) increase in exposure to PM_2.5, PM₁₀, SO₂, NO₂, CO, and O₃, the risk of outpatient and emergency department visits for neurological diseases increased by 7.54% (95%CI: 4.69%, 10.46%), 6.66% (95%CI: 3.92%, 9.46%), 16.72% (95%CI: 10.58%, 23.19%), 8.12% (95%CI: 4.82%, 11.53%), 5.60% (95%CI: 2.34%, 8.97%), and 6.11% (95%CI: 2.91%, 9.40%), respectively. The results of the two-pollutant model showed that the association between PM_2.5 and SO₂ exposure and outpatient and emergency department visits for neurological diseases were relatively stable. The stratified analyses showed that the effect of SO₂ was stronger in the cold season. It was estimated that 8.32% (95%CI: 5.55%, 10.96%) and 6.65% (95%CI: 4.27%, 8.96%) of the outpatient and emergency department visits were attributable to short-term exposure to SO₂ and PM_2.5, respectively. Conclusion Exposure to PM_2.5 and SO₂ is associated with increased risks of outpatient and emergency visits for neurological diseases. SO₂ shows stronger effects during the cold season, and exposure to air pollution contributes to up to 8.32% of neurological disease visits.

Objective:To analyze the clinical characteristics, treatment strategies, and prognostic outcomes of patients infected with Listeria monocytogenes, thereby providing evidence-based insights for the prevention and control of this disease.Methods:A retrospective analysis was performed on the clinical data, diagnostic tests, treatment protocols, and prognostic outcomes of patients definitively diagnosed with Listeria monocytogenes infection at Sichuan Provincial People's Hospital over the past decade. Additionally, a comprehensive literature review was conducted, encompassing studies published between 2014 and 2024, sourced from CNKI, Wanfang Data, and PubMed. This review focused on summarizing the clinical features, treatment regimens, and prognostic outcomes of patients with Listeria monocytogenes infection.Results:The study cohort comprised 17 patients, with a mean age of (61.29 ± 16.24) years. The confirmed cases included 7 cases of bloodstream infections, 3 cases of central nervous system infections, and 7 cases of combined infections. Sepsis developed in 9 patients. The average time from symptom onset to the initiation of empirical antibiotic therapy was 72 hours, while the mean time to definitive diagnosis was 102 hours. Antimicrobial regimens predominantly featured penicillins, meropenem, and vancomycin. The average hospitalization duration was 16 days, with 9 patients experiencing adverse outcomes. A total of 78 relevant literature pieces were retrieved, encompassing data from 85 patients. The average age of these patients was (57.96 ± 16.48) years. Primary diagnostic methods relied on blood/cerebrospinal fluid cultures and Next-Generation Sequencing (NGS). Treatment regimens primarily involved antibiotics such as penicillins, aminoglycosides, carbapenems, and glycopeptides. Despite these interventions, the proportion of patients with poor prognosis remained significantly high at 30.6% (26/85). Logistic regression analysis identified sepsis and delayed antibiotic administration as independent predictors of poor prognosis.Conclusions:Listeriosis, caused by an opportunistic pathogen, necessitates early antibiotic administration and timely identification of at-risk populations to mitigate the risk of poor prognostic outcomes in patients.

Objective To study the feasibility and safety of right ventricular angiography(RVG)to as-sist pacing in the left bundle branch region(LBBaP).Methods The retrospective study was adopted.A total of 67 patients receiving LBBaP in this hospital from January 2019 to June 2022 were included as the study sub-jects.The basic information of the patients was collected,including the sex,age,clinical diagnosis,EKG pa-rameters,etc.The RVG three-stage adjuvant LBBaP was adopted.The specific operation was to perform RVG under the right anterior oblique perspective of 30°.A straight line was connected between the highest point of the tricuspid valvular ring and the apex of the right ventricle,and then the straight line was divided into 3 e-qual parts.The proximal junction was the LBBaP electrode implantation area.The success of LBBaP operation was defined as the simultaneous satisfaction of right bundle branch block form of QRS wave in unipolar pa-cing,QRS wave width(QRSd)＜130 ms and peak time of left ventricular excitation＜90 ms.The operation related parameters and occurrence situation of complications were recorded.The follow up was conducted in 1,3,6,12 months.The electrode parameters,electrocardiogram and color Doppler ultrasound results were recor-ded.Results Among 67 patients,43 cases were males aged(65.0±8.0)years old;twenty-two cases(32.8％)were symptomatic sick sinus syndrome,and 45 cases(67.2％)were second-degree type Ⅱ and above atrioven-tricular block.The preoperative QRS width(QRSd)was(103.0±22.0)ms.The LBBaP operation success was in 61 cases(91.0％).The operation time was(134.6±32.3)min,and the X-ray exposure time was(43.6±12.6)min.The pace-making threshold value was(0.8±0.4)V,the R wave perception amplitude was(12.1±4.7)mV,and the impedance was(741.2±130.8)Ω.At 1 V pacing,the peak time of left ventricular activation in the lead V5 was(83.4±13.7)ms.The postoperative QRSd was(116.5±18.3)ms.During the operation,8 cases developed interventricular septal perforation and 1 case developed bundle branch injury.No other serious complications occurred.After 12 months of follow-up,all patients had stable electrode parame-ters.Conclusion RVG three-stage adjuvant LBBaP is a simple,feasible and safe physiological pacing method.
