Diabetic kidney disease （DKD） is one of the more common chronic kidney diseases，and its causes are complex. DKD is very easy to progress to end-stage renal disease，and the current therapeutic effect still needs to be improved. As an important excretive organ of the human body， the kidney has physiological functions such as discharging metabolic waste， regulating fluid balance， and maintaining the stability of the body's internal environment. These highly complex biochemical processes all depend on the energy support provided by mitochondria. Mitochondrial dysfunction is a key factor causing kidney injury， and the imbalance of mitochondrial homeostasis is an important link leading to mitochondrial dysfunction. The occurrence and development of DKD are often accompanied by the imbalance of mitochondrial homeostasis in renal cells. Mitochondrial autophagy， as a means of regulating mitochondrial homeostasis， is very important for the prevention and treatment of DKD. The PTEN-induced putative kinase 1 （PINK1）/Parkin pathway is one of the most classical pathways to regulate mitochondrial autophagy. Recent studies have found that some drugs can regulate the PINK1/Parkin signaling pathway to target mitochondrial homeostasis and exert renoprotective effects. In particular， traditional Chinese medicine has a significant effect on early and middle stage DKD by regulating PINK1/Parkin pathway-mediated mitochondrial autophagy. This article discussed the mechanism of PINK1/Parkin pathway in mitochondrial autophagy and DKD and reviewed the effect of PINK1/Parkin pathway-mediated mitochondrial autophagy on DKD. At the same time， it explored the therapeutic effect of traditional Chinese and western medicine on DKD mediated by PINK1/Parkin-mediated mitochondrial autophagy， aiming to broaden the ideas of traditional Chinese and western medicine for the prevention and treatment of DKD from the perspective of PINK1/Parkin regulating mitochondrial autophagy.

BACKGROUND:Streptococcus mutans is an important pathogen of dental caries,and timely detection of its levels is of great significance for early detection and treatment of dental caries. OBJECTIVE:To evaluate the effect of loop-mediated isothermal amplification(FTA-LAMP)direct extraction of Streptococcus mutans DNA. METHODS:(1)Bacterial suspensions containing ATCC standard strains(Streptococcus mutans)were prepared and inoculated into the brain-heart leachate medium.After mixed thoroughly,the mixture was then diluted in a 10-fold gradient into seven concentrations(4.2×107,4.2×106,4.2×105,4.2×104,4.2×103,4.2×102,4.2×10 CFU/mL),two parallel controls were made for each dilution level,and sterile water was used as a blank control.(2)The DNA of Streptococcus mutans was extracted using FTA Elute card,boiling method,kit extraction and lysate extraction methods separately and then amplified using LAMP technology was amplified.A specificity test was also performed to compare the differences between the four DNA extraction methods.RESULTS AND CONCLUSION:The DNA extracted by all four methods met the requirements for LAMP amplification.Specificity test results showed that only Streptococcus mutans could specifically amplify the target gene.The detection limit value of the DNA concentration was 4.2×103 CFU/mL for the lysate method,4.2×104 CFU/mL for the FTA Elute card extraction method,4.2×106 CFU/mL for the kit extraction method,and 4.2×107 CFU/mL for the boiling method.In the other aspects of the four extraction methods,the kit extraction method had the highest experimental cost,number of steps and time;the other three methods had the same number of steps,with the FTA Elute card method requiring the least amount of instruments,the boiling method having the lowest single cost,and the lysate extraction method taking the least amount of time.Only a small amount of bacteria were needed for successful extraction using both the FTA Elute card and lysate extraction methods.Compared with the FTA Elute card method,the lysate extraction method was superior in terms of time,but it had a high single cost and required more equipment.To conclude,the FTA-LAMP technology established in this study has the advantages of ease of operation,high specificity,high sensitivity,and visualization,which is expected to be a new way for efficient extraction and detection of Streptococcus mutans.

Renal fibrosis （RF） is the primary pathological feature of chronic kidney disease （CKD） progression to end-stage renal disease （ESRD）， with glomerulosclerosis and tubulointerstitial fibrosis as core pathological manifestations. It involves abnormal accumulation of extracellular matrix （ECM） components such as collagen and fibronectin， ultimately leading to structural destruction and functional losses of the kidneys. Sirtuins （SIRTs）， a class of nicotinamide adenine dinucleotide （NAD+）-dependent deacetylases， play crucial roles in cellular metabolism， oxidative stress responses， inflammation regulation， and cell survival. In mammals， there are seven distinct SIRT members （SIRT1 to SIRT7）， which collectively ameliorate RF progression through multiple pathways. These include regulating the transforming growth factor （TGF）-β/Smad signaling pathway， suppressing inflammatory responses， reducing oxidative stress， modulating mitochondrial and autophagy functions， and promoting fatty acid oxidation. In recent years， traditional Chinese medicine （TCM） and its active components have demonstrated significant potential in activating or modulating the SIRT protease family and its regulatory networks to ameliorate RF in a multi-target and holistic manner. However， systematic reviews in this area remain lacking. This article elucidates the mechanisms by which the SIRT protease family regulates RF and reviews the latest research advances in TCM modulation of SIRTs for the prevention and treatment of RF， aiming to provide new insights and approaches for the TCM treatment of RF.

BACKGROUND: The use of potentially inappropriate medications (PIMs) is a major concern for medication safety as it may entail more harm than potential benefits for older adults. This study aimed to explore the prescribing rate, healthcare utilization, and expenditure of older adults using PIMs in China. METHODS: A cross-sectional analysis was conducted using a national representative database of all medical insurance beneficiaries across China, extracting ambulatory visit records of adults aged 65 years and above between 2015 and 2017. Descriptive analysis was conducted to measure the rate of patients exposed to PIM, prescribing rate of each PIM, average annual outpatient visits per patient, average total medication costs for each visit, average annual cost of PIMs for each patient, and average annual medication costs for each patient. Generalized linear model with logit link function and binomial distribution was used to examine the adjusted associations between PIMs and independent variables. RESULTS: In total, 845,278 (33.2%) participants were identified to be exposed to at least one PIM. Patients aged 75-84 years (38.1%, 969,809/2,545,430) and ≥85 years (37.9%, 964,718/2,545,430) were more likely to be prescribed with PIMs. Beneficiaries of the Urban Employee Basic Medical Insurance (UEBMI) and living in eastern and southern regions were more frequently prescribed with PIMs. Compared with patients without PIM exposure (7.5 visits, drug cost of RMB 1545.0 Yuan), patients with PIM exposure showed higher adjusted average annual number of outpatient visits (10.7 visits, β = 3.228, 95% confidence interval [CI] = 3.196-3.261) and higher annual drug costs (RMB 2461.8 Yuan, Coef. = 916.864, 95% CI = RMB 906.292-927.436 Yuan). CONCLUSIONS The results showed that the use of PIM among older adults was common in China. This study suggests that the use of PIM could be considered as a clear target, pending multidimensional efforts, to promote rational prescribing for older adults.

BACKGROUND: Gout is a chronic disease primarily caused by elevated urate levels, severely affecting joint health. Its global distribution varies, and updated data for China are lacking. This study aimed to analyze the current burden and trends of gout globally and in China, examining the burden by gender, age, and risk factors while providing future predictions. METHODS: This descriptive epidemiological secondary analysis utilized data from the Global Burden of Disease, Injuries, and Risk Factors (GBD) 2021 study. Age-standardized incidence rate (ASIR), prevalence rate (ASPR), and disability-adjusted life years (DALYs) rates (ASDR) were used to assess the gout burden. Trends from 1990 to 2021 were analyzed across global regions, genders, and sociodemographic index (SDI) levels. The burden in China was further examined by gender, age, and associated risk factors. The Bayesian age-period-cohort (BAPC) model was used to predict future trends. Gout burden in China and the United States was compared. RESULTS: In 2021, gout affected 57 million people globally, with 9.4 million new cases and 1.75 million DALYs. From 1990 to 2021, the ASIR, ASPR, and ASDR increased by 17.2%, 21.9%, and 21.3%, respectively. Males experienced a significantly higher burden, with greater ASIR, ASPR, and ASDR increasing with higher SDI levels. In China, male ASIR, ASPR, and ASDR were over 2.8 times those of females, and the burden increased with age. In 2021, 31.4% of gout-related DALYs in China were attributed to high body mass index and 7.6% to kidney dysfunction. Between 1990 and 2021, the high body mass index-related burden of gout rose annually for both genders, while the kidney dysfunction-related gout burden remained stable. By 2050, the burden of gout in China is expected to continue increasing, with a slower rise in females and a decline in males after an initial increase. However, the overall burden will remain substantial. In comparison, the gout burden will be higher in the United States than in China. CONCLUSIONS Gout is becoming a significant health burden globally and in China, particularly among Chinese males and older individuals. With the aging population and lifestyle changes exacerbating the issue, effective strategies and measures are essential to prevent or reduce gout-related health issues.

Objective To investigate the efficacy of sevelamer(SL)and calcium acetate(CA)in treating hyperphosphatemia in patients with end-stage renal disease(ESRD)undergoing maintenance hemodialysis(MHD)and their effects on calcium-phosphorus metabolism and levels of peripheral blood fetuin-A and fibroblast growth factor-23(FGF-23).Methods A total of 92 ESRD patients attending the First Hospital of Zibo between January 2022 and December 2023 were enrolled.They were randomly assigned to either the CA group(46 cases)or the SL group(46 cases)using a random number table method.Patients in both groups received MHD and conventional treatment.Additionally,patients in the CA group were given CA,while those in the SL group were given SL,with the treatment continuing for 3 months.The outcome indicators were assessed and compared between the two groups.The primary outcome indicator was clinical efficacy.The secondary outcome indicators included calcium-phosphorus metabolism indicators(blood calcium,blood phosphorus,calcium-phosphorus product,and intact parathyroid hormone[iPTH]),coronary artery calcification score(CACs),serum biochemical indicators(including fetuin-A,FGF-23,and C-reactive protein[CRP]),and adverse reactions and cardiovascular events during the course of treatment.Results There were no statistically significant differences in baseline data between the two groups(P>0.05).There was a significant difference in clinical efficacy between the SL group and the CA group(P<0.05).The differences in blood calcium,blood phosphorus,calcium-phosphorus product,iPTH,and CACs before and after treatment were statistically significant between the two groups(P<0.05).The differences in fetuin-A,FGF-23,and CRP before and after treatment were also statistically significant between the two groups(P<0.05).During treatment,there was no significant difference in the incidences of adverse reactions and cardiovascular events between the two groups(P>0.05).Conclusion SL demonstrates superior efficacy compared to CA in treating hyperphosphatemia in MHD patients.SL effectively regulates calcium-phosphorus metabolism,reduces CACs,regulates peripheral blood fetuin-A and FGF-23 levels,and leads to fewer adverse reactions.SL may be a preferred option for clinical management.

Objective:To investigate the impact of early invasive arterial blood pressure (IBP) monitoring on survival and neurological outcomes in out-of-hospital cardiac arrest (OHCA) patients undergoing extracorporeal cardiopulmonary resuscitation (ECPR).Methods:This retrospective cohort study analyzed 44 OHCA patients receiving ECPR between January 2021 and January 2023. Patients were divided into: Early intervention group : IBP established within 3 min of ECMO initiation; Late intervention group : IBP established after ICU admission. Baseline characteristics, ECMO parameters, and clinical outcomes were compared. Multivariable logistic regression (adjusted for age, initial rhythm, etc.) and Spearman's correlation were used.Results:This study included a total of 44 patients treated with OHCA and ECPR, divided into an early intervention group of 23 cases and a late intervention group of 21 cases. The early intervention group showed significantly higher: Survival to discharge (43.5% vs. 9.5%, P<0.05), Good neurological recovery (CPC 1-2: 34.8% vs. 9.5%, P<0.05).Early intervention independently predicted survival (adjusted OR=18.84, 95% CI:1.97-179.98, P=0.01). Stratified analysis by pH (cutoff 7.0) demonstrated consistent benefits in both pH>7.0 ( aOR=0.392, 95% CI:0.106-0.678) and pH≤7.0 subgroups ( aOR=0.385, 95% CI: 0.075-0.695; interaction P=0.183). Early IBP positively correlated with CPC scores ( ρ=0.40, P=0.007). Conclusions:Early IBP monitoring significantly improves survival and neurological outcomes in OHCA-ECPR patients, supporting its integration into standardized protocols.

Human parvovirus B19 (HPVB19) belongs to Parvoviridae, a genus of erythrovirus, and has been associated with various human diseases, and HPVB19 infection is one of the most important causes of refractory anemia after allogeneic hematopoietic stem cell transplantation (allo-HSCT). This study retrospectively analyzed 24 patients with HSCT combined with HPVB19 infection to collate and summarize the clinical presentation, treatment, and regression of patients with combined HPVB19 infection after allo-HSCT and provide experience in the management of HPVB19 infection after allo-HSCT. The median age of the patients with HPVB19 infection was 25 years, and the median time of infection occurrence was +107 days after transplantation, and 22 (91.7% ) had anemia with a median hemoglobin (HGB) level of 77.5 (46-149) g/L, and 13 (54.2% ) had new-onset anemia or persistent decline in HGB. The median length of hospital stay was 19 days. Among patients with new-onset anemia or persistent decline in HGB, the mean increase in HGB after treatment with intravenous immunoglobulin and/or antiviral therapy was 15.69 g/L, and treatment was effective in 10 (76.92% ) patients. HPVB19 infection should be alerted to the development of refractory anemia after HSCT; despite the lack of specific treatment, the overall prognosis of HPVB19-infected patients is good.

Objective:To explore the effects of estrogen receptor α (ERα) encoded by protein encoding gene ESR1 on the radiation resistance of breast cancer cells and their molecular mechanisms.Methods:The ESR1 overexpression plasmid was transfected into estrogen receptor (ER)-negative breast cancer cells. Then, the shRNA-ESR1 vector was introduced into ER-positive cell to establish models with different phenotype. The ATG5 mRNA level and protein expression levels of LC3B-I, LC3B-II, P62, FIP200, ATG5, ATG7, ATG12, Beclin1, ULK1 were detected using qPCR and Western blot techniques. Cell death was measured using flow cytometry. The radiation sensitivity was determined through the colony formation assay. The mortality of breast cancer cells under the autophagy gene knockdown and overexpression or treated with estrogen receptor inhibitor (TAM) combined with ionizing radiation were detected by trypan blue staining.Results:Under the condition of 8 Gy X-ray irradiation, the knockdown of ESR1 in ER-positive ZR75 breast cancer cells promoted cell death ( t = 3.49, 3.13, P < 0.05), while the overexpression of ESR1 in ER-negative MDA-MB-231 breast cancer cells inhibited cell death ( t = 4.16, 7.48, P < 0.05). Compared to the control group, the treatment with chloroquine increased the number of formed colonies of ESR1 knockdown ZR75 cells ( t = 8.49, P < 0.05), and inhibiting autophagy could reduce the death of ZR75 cells caused by ESR1 silencing. Under the treatment with ionizing radiation, the overexpression of ESR1 in MDA-MB-231 cells promoted protective autophagy, which, however, was reduced after ESR1 knockdown in ZR75 cells. Furthermore, it was observed that the knockdown of ATG5 in ZR75 cells was associated with reduced autophagy and an increase in cell death ( t = 4.19, 6.39, P < 0.05). In contrast, the overexpression of ATG5 in ZR75 cells reversed the increase in cell death caused by ESR1 knockdown ( t = 1.70, 4.65, P < 0.05). After the treatment of ER-positive ZR75 breast cancer cells with TAM, the expressions of ATG5 and ATG12 decreased, suggesting inhibited autophagy and an increase in cell death ( t = 18.70, P < 0.05). Furthermore, these processes were promoted by ionizing radiation ( t = 16.82, P < 0.05). Conclusions:The estrogen receptor encoded by ESR1 promotes protective autophagy of ER-positive breast cancer cells by increasing ATG5, further leading to radiation resistance in ER-positive breast cancer cells. Treatment with tamoxifen combined with ionizing radiation can increase the radiation sensitivity of ER-positive breast cancer cells.
