ObjectiveTo observe the effect of Qishao capsules on renal injury in db/db mice with diabetic kidney disease （DKD），and explore its mechanism of protecting the kidney by inhibiting podocyte apoptosis. Methodsdb/m mice （7 mice） were used as the normal group，and db/db mice （35 mice） were randomly divided into a model group，a dapagliflozin group （0.001 g·kg^-1·d^-1），and low-，medium-，and high-dose groups of Qishao capsules （0.341 3，0.682 5，and 1.365 g·kg^-1·d^-1，respectively）. Drug intervention lasted for 8 consecutive weeks. After sampling，the serum renal function indicators ［creatinine（SCr），and urea nitrogen（BUN）］，fasting blood glucose （FBG），24 h urinary protein quantification （24 h-UTP）， and other indicators of the mice were measured. The pathological tissue morphology of the kidney was observed by periodic acid-silver methenamine （PASM） and Masson's trichrome （Masson） staining. Immunohistochemical detection of cysteine-dependent aspartate-specific protease （Caspase）-3 and B-cell lymphoma 2 （Bcl-2） was performed. Western blot was used to detect the protein expression of Caspase-8，Caspase-7，Caspase-3， and other molecules. Terminal deoxynucleotidyl transferase dUTP nick End labeling （TUNEL） staining was used to observe apoptosis in renal tissue. Immunofluorescence staining of Wilms tumor suppressor gene-1 （WT-1） was used to observe podocyte injury. Real-time polymerase chain reaction （Real-time PCR） was employed to detect Caspase-8 and Caspase-3 mRNA expression in the kidneys of experimental mice. Data analysis was conducted using statistical software GraphPad Prism 10. ResultsCompared with the normal group，the model group showed significantly increased 24 h-UTP，SCr，BUN，and FBG （P<0.01）. Additionally， PASM staining of renal tissue showed increased glycogen deposition，glomerular hypertrophy，and thickening of the basement membrane. Masson staining showed collagen fiber proliferation in renal tissue. Transmission electron microscopy showed thickening of the renal tissue basement membrane and fusion or loss of foot processes in the model group. The immunohistochemical results showed that Caspase-3 in the kidneys of the mice in the model group significantly increased （P<0.01），while the Bcl-2 protein expression level decreased significantly （P<0.01）. The number of TUNEL positive cells in renal tissue significantly increased （P<0.01）. The positive expression of WT-1 in podocytes was significantly reduced （P<0.01）. Western blot analysis showed significant upregulation of Caspase-8，Caspase-7，and Caspase-3 protein expression in renal tissue （P<0.01）. The mRNA expression levels of Caspase-8 and Caspase-3 in the kidneys increased significantly （P<0.01）. Compared with the model group，the Qishao capsules groups can significantly reduce the levels of 24 h-UTP，SCr，BUN，and FBG （P<0.01）. The pathological damage of renal tissue and podocyte injury were improved to some extent. Immunohistochemistry in the kidney showed a significant decrease in Caspase-3 （P<0.01） and a significant increase in Bcl-2 protein expression level （P<0.01）. Additionally， there were a significant decrease in the number of TUNEL positive cells in renal tissue （P<0.01），a significant increase in WT-1 positive expression in podocytes （P<0.01），marked downregulation of Caspase-8，Caspase-7，and Caspase-3 protein expression in renal tissue （P<0.05，P<0.01），and a significant decrease in Caspase-8 and Caspase-3 mRNA expression levels （P<0.01）. ConclusionQishao capsules can inhibit podocyte apoptosis by regulating the expression of Caspase-8，Caspase-7， and Caspase-3，thereby improving the diabetic renal injury in db/db mice.

Attention deficit hyperactivity disorder （ADHD） is often accompanied by tic disorder. The core pathogenesis is considered to be ministerial fire scorching yin and internal stirring of deficient wind， which leads to disharmony between the body and spirit， resulting in clinical manifestations. The treatment principles emphasize nourishing yin fluids， calming ministerial fire， and extinguishing endogenous wind （内风）. The method of nourishing yin fluids is applied throughout the entire treatment process， commonly using ingredients such as Shudihuang （Rehmanniae Radix Praeparata）， Shanzhuyu （Corni Fructus）， Gouqizi （Lycii Fructus）， Wuweizi （Schisandrae Chinensis Fructus）， and Tusizi （Cuscutae Semen）. These are combined with approaches to harmonize the zang-fu organs， primarily including extinguishing liver wind， clearing heart fire， nourishing kidney water， and strengthening spleen earth， thereby stabilizing ministerial fire and extinguishing endogenous wind. Additionally， emotional regulation and smoothing emotional constraint are essential to improve clinical symptoms in children with ADHD comorbid with tic disorder.

ObjectiveTo investigate the therapeutic efficacy of Qizhi Tongluo granules on proteinuria in membranous nephropathy （MN） and its potential protective effects and underlying mechanism against endoplasmic reticulum stress. MethodsAfter 70 Sprague-Dawley （SD） rats were adaptively fed for one week， the MN rat model was established by injecting cationic bovine serum albumin （C-BSA） into the tail vein. Rats were divided into the normal group， model group， low-dose Qizhi Tongluo granules group （2.43 g·kg^-1）， medium-dose group （4.86 g·kg^-1）， high-dose group （9.72 g·kg^-1）， and benazepril group （0.01 g·kg^-1）， with 10 rats in each group. Treatment was administered for four weeks. The 24-hour urinary total protein （UTP） content， as well as the levels of reactive oxygen species （ROS）， malondialdehyde （MDA）， and glutathione peroxidase （GPX） in renal tissues， were measured. Renal pathological changes were assessed using immunoglobulin G （IgG） staining， periodic acid-silver methenamine （PASM） staining， and transmission electron microscopy （TEM）. The localization and expression levels of glucose-regulated protein 78 （GRP78）， phosphorylated inositol-requiring enzyme 1α （p-IRE1α）， phosphorylated protein kinase R-like endoplasmic reticulum kinase （p-PERK）， activating transcription factor 4 （ATF4）， nuclear factor erythroid 2-related factor 2 （Nrf2）， and 2'-5' oligoadenylate synthetase-like protein 1 （OASL1） in rat kidneys were detected by immunohistochemistry （IHC）. The mRNA and protein expression levels of Nrf2， thioredoxin 1 （Trx1）， thioredoxin-interacting protein （TXNIP）， and OASL1 in rat kidneys were measured using real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot analysis. ResultsCompared with the normal group， UTP levels were significantly increased in the model rats （P<0.05）， with obvious renal pathological damage. GPX content levels were significantly decreased in renal tissue （P<0.05）， while ROS and MDA content levels were significantly increased （P<0.05）. The expression of GRP78， p-IRE1α， p-PERK， and ATF4 proteins was significantly increased in the kidneys （P<0.05）， while the mRNA and protein expression levels of Trx1 and Nrf2 were significantly decreased （P<0.05）. The mRNA and protein expression levels of TXNIP and OASL1 were significantly increased （P<0.05）. Compared with the model group， the UTP levels of rats in the Qizhi Tongluo granules groups and the benazepril group decreased to varying degrees （P<0.05）， and renal pathological damage was significantly alleviated. The GPX content in renal tissue was significantly increased （P<0.05）， while the ROS and MDA levels were significantly decreased （P<0.05）. The expression of GRP78， p-IRE1α， p-PERK， and ATF4 proteins in the kidney was significantly decreased （P<0.05）. The mRNA and protein expression levels of Trx1 and Nrf2 were significantly increased （P<0.05）， while the mRNA and protein expression levels of TXNIP and OASL1 were significantly decreased （P<0.05）. ConclusionQizhi Tongluo granules alleviates proteinuria in MN rats by modulating the Nrf2/OASL1 signaling pathway in renal tissues to reduce endoplasmic reticulum stress， which represents its underlying mechanism.

The clinical diagnosis and treatment of urinary tract infection has long faced the challenges of insufficient standardization of diagnosis and treatment pathways,irrational use of antimicrobial drugs and high recurrence rate.How to optimize the hierarchical diagnosis and treatment pathway of urinary tract infection,standardize the use of antimicrobial drugs,and reduce the recurrence rate have always been the focus of clinical attention.There is significant heterogeneity in the existing diagnostic criteria for urinary tract infection,which seriously affects the comparability and evidence integration of clinical and research studies.In order to solve the above problems,a consensus on global multidisciplinary diagnostic criteria for urinary tract infection has been formed by international multidisciplinary experts after three rounds of Delphi method.Breaking through the traditional classification framework,the consensus innovatively established a four-dimensional quantitative scoring system including local symptoms and signs,systemic inflammatory response,quantitative analysis of pyuria and urine culture results,and established a hierarchical standard for stepwise urinary tract diagnosis according to the scoring threshold.Based on the key citations related to the consensus,this paper interprets in detail the basis for the selection of core indicators and the establishment of thresholds for the diagnosis of urinary tract infection in the consensus,and focuses on the key issues and implementation paths of the consensus in localization practice.This consensus provides a unified standard for standardizing the clinical diagnosis and treatment of urinary tract infection,improving the homogeneity of clinical research through standardized diagnostic processes,and promoting the standardization of UTI drug research and development and the rational use of antibiotics and precision.

Steroid-induced osteonecrosis of the femoral head(SNOFH)is a prevalent challenging condition in orthopedics,characterized by a high disability rate and intricate pathophysiological mechanisms including diminished an-giogenesis and impaired osteogenic function.The concept of osteogenesis-angiogenesis coupling involves the interplay be-tween osteoblasts and angiogenesis.Restoring the blood supply to bone tissue,boosting bone cell activity,and facilitating bone regeneration are crucial for the recovery of SNOFH patients.Research has demonstrated the significant role of mi-croRNAs(miRNAs)in the coordination of osteogenesis and angiogenesis.MiRNAs have the ability to concurrently regu-late multiple target genes and signaling pathways associated with osteogenesis and angiogenesis,effectively stimulating the regeneration of bones and blood vessels.By considering the interaction of multiple miRNAs and their target genes,the de-velopment of a multi-target combination therapy approach could greatly enhance the treatment outcomes for SNOFH.Through a thorough investigation of miRNA interactions in the regulation of osteogenesis and angiogenesis,the progression of the disease can be elucidated,offering a fundamental basis for early diagnosis,precise treatment,and prognosis evalua-tion of SNOFH.This paper aims to uncover the pivotal nodes and regulatory connections in SNOFH by summarizing the in-volvement of miRNAs in the coupling of osteogenesis and angiogenesis.By identifying potential therapeutic targets and un-derstanding the coordinated function of miRNAs in osteogenesis and angiogenesis coupling,valuable insights can be gained for the personalized treatment of SNOFH.

Objective To explore the characteristics of incorrect opinions in re-examination cases,analyze the reasons,characteristics,and commonalities of different forensic opinions in the same injury case during re-examination,and provide references for similar case acceptance,forensic procedures,analysis and argumentation,and the application of relevant provisions.Methods A retrospective analysis was conducted on the re-examination cases of human injury degree accepted by the Forensic Judicial Appraisal Center of Guizhou Medical University and West China Forensic Medical Appraisal Center of Sichuan University from January 2020 to December 2024.Results Among the 81 collected re-examination cases of human injury degree,the injury types mainly included fractures,soft tissue injuries,tendon injuries,craniocerebral injuries,nerve injuries,joint injuries,and organ injuries.Of these,74 cases were entrusted by the public security system,and 72 cases used primary injuries as the basis for assessment.Seven cases had more than 3 appraisals and 74 cases had two appraisals,of which 53 cases had inconsistent opinions between the previous and current appraisals,including 29 cases with an upgraded injury grade and 24 cases with a downgraded injury grade.Conclusion When accepting re-examination cases,forensic experts need to choose relevant objective examination techniques in forensic clinical medicine,such as clinical imaging techniques,to determine whether imaging data serves as key evidence in the case,and seek assistance from experts in related fields when necessary.In the case acceptance stage,it is necessary to collect and review key assessment materials such as medical records,the first assessment opinion,and interrogation records.Forensic experts should also enhance their understanding of legal provisions,timing of assessment,their image-reading ability,and work to standardize the forensic assessment process.

Objective:To report two cases of anti-glomerular basement membrane (GBM) disease with IgA nephropathy (IgAN), and summarize the clinical characteristics of these patients through systematic literature review, for providing clinical data for the diagnosis and treatment of this disease.Methods:It was a case-series analysis. Clinical data of two cases with anti-GBM disease and IgAN diagnosed in the First Affiliated Hospital of Guangxi Medical University were collected. The course of their diagnosis and treatment was described. Besides, the relevant literature of anti-GBM disease with IgAN cases reported in PubMed and CNKI databases from the establishment of the database to June 30, 2024 were retrived, and the relevant clinical data were extracted for analysis and summary. Patients were divided into end-stage renal disease (ESRD) group and non-ESRD group according to renal outcome, and the differences in age, gender, hemoglobin, creatinine at diagnosis, proportion of hypuria/anuria, qualitative grade of urinary protein, and proportion of renal crescent were compared between the two groups.Results:Two patients were both young women. The pathology of renal tissue suggested crescentic glomerulonephritis. The pathological manifestations were linear deposition of IgG along GBM and deposition of immune complex dominated by IgA in mesangial region. At the initial diagnosis, the renal function damage of the case one was not severe. After plasma exchange, glucocorticoid and cyclophosphamide treatment, the renal function recovered. The kidney function of the case two was obviously impaired at the initial diagnosis, and was improved after the above treatment, but aggravated due to infection, and continued to progress into ESRD. Twenty-six literates involving 40 cases of anti-GBM disease with IgAN were retrieved. A total of 42 cases of anti-GBM disease with IgAN, including 2 cases in this report, were analyzed and summarized. The age was (41.3±17.5) years old, 45.2% were male, 39 cases (92.9%) were from Asia. The hemoglobin was (94.4±15.1) g/L, the serum creatinine was 450.8 (284.4, 755.8) μmol/L, 83.3% (35/42) patients had crescent ratio greater than 50% and 37 patients (88.1%) patients were treated with intravenous methylprednisolone and cytotoxic immunosuppressive drugs. Plasma exchange was performed in 34 patients (81.0%) patients, 23 patients (54.8%) had renal function recovered and 17 patients (40.5%) entered ESRD. Compared with the non-ESRD group, the serum creatinine in the ESRD group was higher at initial diagnosis ( P<0.01), and the proportion of hypuria/anuria was higher ( P=0.03). There were no statistically significant differences in age, sex, hemoglobin, urinary protein and crescent proportion between the two groups (all P>0.05). Conclusions:Compared with anti-GBM disease, anti-GBM with IgAN has a smoother course and a better prognosis. Infection should be actively prevented during treatment.
