Objective:To explore the epidemiological characteristics, clinical manifestations, laboratory findings, and imaging features of children with HRV-associated pneumonia, and to analyze the clinical features and risk factors associated with severe HRV pneumonia, providing references for clinical management.Methods:A single-center, retrospective, observational study was conducted, including 1 001 cases of HRV-positive children with pneumonia admitted to the Respiratory Department of the Affiliated Children′s Hospital of Capital Institute of Pediatrics from January 2019 to December 2023. Among them, 584 cases (58.3%) were male and 417 cases (41.7%) were female, with an age range of 0.1 to 14.9 years, a median age of 3.42 years, and a mean age of (3.92±2.75) years. According to clinical guidelines, the cases were divided into a mild pneumonia group (855 cases, 510 males, 345 females) and a severe pneumonia group (146 cases, 73 males, 73 females). Basic information, clinical, laboratory, and imaging data were collected from the electronic medical record system. Comparisons between different age groups, diagnoses, and pneumonia severity groups were performed using the χ2 test. Multivariate logistic regression analysis was used to identify risk factors for the severity of HRV pneumonia. Results:Among the 1 001 cases of HRV-associated bronchopneumonia, 146 cases (14.6%) were severe pneumonia. The age of severe HRV pneumonia patients was significantly higher than that of the mild pneumonia group (5.2 years vs. 3.7 years, t=-6.050, P<0.01). Severe HRV pneumonia had a higher incidence in autumn and winter (60.9%). Severe HRV pneumonia was associated with higher levels of lactate dehydrogenase (LDH), C-reactive protein (CRP), neutrophils, and creatinine (correlation coefficients 0.198, 0.334, 0.104, 0.142, P<0.01), and lower levels of albumin (correlation coefficient 0.308, P<0.01). Multivariate logistic regression analysis showed that co-infection with Streptococcus pneumoniae or Mycoplasma was an independent risk factor for severe HRV pneumonia [ OR=1.611, 95% confidence interval ( CI):1.066-2.435, P<0.05; OR=3.355, 95% CI:2.062-5.458, P<0.01]. Conclusion:The infection rate of HRV is higher in preschool and school-age children. Severe HRV pneumonia is associated with increased levels of LDH, CRP, neutrophils, and creatinine, as well as decreased levels of albumin. Co-infection with Streptococcus pneumoniae or Mycoplasma may be an independent risk factor for severe HRV pneumonia. High-risk children require enhanced monitoring and early intervention to improve prognosis.

Objective: To investigate the effects of Zuogui Jiangtang Yishen Formula (左归降糖益肾方, ZGJTYSF) in regulating the nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3)/caspase-1/gasdermin D (GSDMD) signaling axis on pyroptosis in rats with diabetic kidney disease (DKD). Methods: Fifty male specific pathogen-free (SPF) grade Goto-Kakizaki (GK) rats (12 weeks old) were fed a high-fat diet for one month to establish an early DKD model. Model establishment was confirmed when fasting blood glucose (FBG) ≥ 11.1 mmol/L and urinary albumin-to-creatinine ratio (uACR) ≥ 30 mg/g. The successfully modeled early DKD rats were randomly divided by random number table into five groups (n = 10 per group): model group; dapagliflozin group (1.0 mg/kg, by gavage, served as positive control); and low-, medium-, and high-dose of ZGJTYSF groups (4.9, 9.9, and 19.9 g/kg, respectively, by gavage). Age-matched male SPF Wistar rats (n = 10) served as control group. Rats in control and model groups were gavaged with equivalent volumes of distilled water. Treatment lasted 12 weeks. Changes in uACR, FBG, and renal function were observed in all groups. Hematoxylin-eosin (HE), periodic acid-Schiff (PAS), and Masson staining were used to observe renal histopathological changes. Immunohistochemistry was performed to detect the localization and expression of caspase-1, GSDMD, and NLRP3 in rat renal tissues. Terminal deoxynucleotidyl transferase deoxyuridine triphosphate (dUTP) nick end labeling (TUNEL) was utilized to detect pyroptosis in renal tissues. Quantitative real-time polymerase chain reaction (qPCR) and Western blot were applied to detect mRNA and protein expression levels of NLRP3, caspase-1, GSDMD, interleukin (IL)-1β, and IL-18. Results: Compared with model group, all doses of ZGJTYSF showed reductions in FBG, with medium- and high-dose of ZGJTYSF groups demonstrating significant decreases at week 8 and 12 (P < 0.05). For uACR, all doses of ZGJTYSF groups exhibited a decreasing trend, with high-dose of ZGJTYSF group being significantly lower than low- and medium-dose of ZGJTYSF groups at week 12 (P < 0.05) and showing no significant difference from dapagliflozin group (P > 0.05). No significant differences in renal function parameters (serum creatinine, blood urea nitrogen, and uric acid) were observed among groups (P > 0.05). Histopathological examination revealed milder glomerular and tubular lesions in both ZGJTYSF groups and dapagliflozin group, with renal pathological changes in high-dose of ZGJTYSF group resembling those in dapagliflozin group. Immunohistochemistry demonstrated significantly reduced expression of caspase-1, GSDMD, and NLRP3 in renal tissues of dapagliflozin group and high-dose of ZGJTYSF group compared with model group (P < 0.05 or P < 0.01), while the differences in low- and medium-dose of ZGJTYSF groups were not statistically significant (P > 0.05). TUNEL assay showed significantly fewer TUNEL-positive cells in renal tissues of dapagliflozin and high-dose of ZGJTYSF groups (P < 0.01), indicating a marked reduction in pyroptotic cells. Molecular analysis revealed that compared with model group, both dapagliflozin and high-dose of ZGJTYSF groups showed significantly downregulated mRNA and protein expression levels of NLRP3, caspase-1, GSDMD, IL-1β, and IL-18 in renal tissues (P < 0.01), while low- and medium-dose of ZGJTYSF groups showed downward trends without statistical significance (P > 0.05). Conclusion ZGJTYSF may inhibit renal pyroptosis by regulating the NLRP3/caspase-1/GSDMD signaling axis, thereby preventing and treating early renal injury in DKD and delaying the onset and progression of DKD.

Objective:To observe the diuretic effects of Zhuling Decoction on mice with adriamycin nephropathy (ADRN); To explore its mechanism.Methods:Totally 32 SPF male C57BL/6 mice were divided into a blank group of 7 mice and a model group of 25 mice using a random number table method. ADRN model was prepared by single tail vein injection of 0.01 g/kg of amphotericin. Two weeks later, the successfully modeled mice were divided into a model group (7 mice), a furosemide group (8 mice), and a Zhuling Decoction group (8 mice). The blank group and model group mice were given equal volumes of injection water by gavage. The furosemide group was given 2.6 mg/kg of furosemide by gavage, and the Zhuling Decoction group was given 6.5 g/kg of Zhuling Decoction by gavage, once a day, for 8 consecutive weeks. Changes in body weight and urine output of mice were observed. A biochemical analyzer was used to detect 24-hour urinary protein quantification and blood potassium and SCr levels in mice. HE staining was used to observe pathological changes in mouse kidneys, and immunohistochemistry and Western blot were used to detect the homology of cyclin dependent kinase 18 (CDK18), STIP1, and the expressions of U-box protein 1 (STUB1) and aquaporin 2 (AQP2) in mouse kidney tissue cells.Results:Compared with the model group, both the furosemide and Zhuling Decoction groups exhibited increased 24-hour urine output ( P<0.05); compared with the model group and furosemide group, Zhuling Decoction group showed reduced average optical density values and protein expressions of CDK18 and AQP2 ( P<0.05) and increased STUB1 average optical density value and protein expression ( P<0.05). Conclusion:Zhuling Decoction can increase 24-hour urine output in ADRN mice, and the mechanism may be related to down-regulation of CDK18 and AQP2 protein expressions and up-regulation of STUB1 protein expression, thereby modulating the CDK18/STUB1/AQP2 pathway and reducing water reabsorption.

Objective lo contrast the diagnostic efficacies of perineal and transrectal approaches for combined prostate biopsies guided via magnetic resonance imaging(MRI)and ultrasound fusion imaging.Method A retrospective analysis of clinical data from 271 patients subjected to combined prostate biopsies guided by MRI and ultrasound fusion imaging at the first people's hospital of Wuxue city and Wuhan Tongji Hospital from January 2022 to November 2023 was conducted.They were divided into two groups according to the puncture path,132 cases were transrectal and 139 cases were perineal.The differences between the detection rates of prostate cancer(PCa)and clinical significant prostate cancer(csPCa)across different prostate imaging reporting and data system(PI-RADS)scores and lesion localizations within the two puncture paths were compared.Results The detection rates of PCa in the perineal and transrectal puncture groups(68.3％vs.59.8％,P=0.145)and csPCa(64.7％vs.55.3％,P=0.112)did not exhibit statistically significant differences.However,the perineal puncture group experienced fewer complications.For patients with a PI-RADS score of 4,both PCa(77.2％vs.56.1％,P=0.027)and csPCa(71.9％vs.48.8％,P=0.02)detection rates were higher via the perineal combined biopsy),compared to the transrectal path.Additionally,for apical(PCa:84.3％vs.48.7％,P=0.001;csPCa:81.8％vs.48.7％,P=0.004)and anterior(PCa:77.1％vs.46.5％,P=0.006;csPCa:68.6％vs.44.2％,P=0.031)prostate lesions,the detection rates via the perineal combined biopsy were considerably higher than those of the transrectal path.Conclusion For patients carrying a PI-RADS score of 4 or with prostate lesions situated at the apical or anterior section,the perineal approach for biopsy sampling emerges as the most appropriate method.

It is estimated that approximately seven million people worldwide are affected by inflammatory bowel disease(IBD),causing a huge burden on healthcare systems and society.In the occurrence,progression,and treatment of IBD,the intestinal microbiota and its key metabolic product,bile acids,play a crucial role.The intestinal microbiota not only participates in the biotransformation of bile acids,enriching the diversity of bile acids,but also regulates their synthesis and transport through the farnesoid X receptor(FXR).Meanwhile,bile acids contribute to regulating the structure and function of the intestinal microbiota by supporting microbial diversity,exerting direct toxicity,participating in indirect antimicrobial pathways,and influencing microbial metabolic capabilities.Furthermore,under normal physiological conditions,intestinal microbiota-derived bile acids facilitate the repair process of the intestinal epithelial barrier.They also promote the balance of the immune system by modulating the functions of various immune cells including helper T(Th)cells 17,regulatory T(Treg)cells,CD8+T cells and natural killer T(NKT)cells,thereby slowing down the development of IBD.This article focuses on exploring the role of intestinal microbiota and bile acids in the onset and progression of IBD,and investigating new effective treatment strategies by targeting intestinal microbiota and bile acids,such as bile acid receptor modulators,probiotics,prebiotics,fecal microbiota transplantation(FMT),and phage therapy.

Background Permethrin is a commonly used pyrethroid insecticide and has been found to be potentially neurotoxic. Microglia are innate immune cells in the central nervous system and are involved in the development of a range of neurodegenerative diseases. Objective To observe possible toxic effects of permethrin on human microglia clone 3 (HMC3) in vitro and explore associated mechanism. Methods HMC3 were treated with 0, 10, 25, and 55 μmol·L⁻¹ permethrin for 72 h. Cell cycle and apoptosis were measured using flow cytometry. Cyclin-dependent kinase 1 (CDK1), cyclin-dependent kinase inhibitor 1A (CDKN1A), cyclin B2 (CCNB2), cellular tumor antigen p53 (p53), factor-related apoptosis (FAS), caspase 3 (CASP3), and H2A histone family member X (H2AX) were detected by quantitative real-time PCR (qPCR). The differential genes and enrichment pathways of HMC3 after 0 and 25 μmol·L⁻¹ permethrin treatment was analyzed by RNA sequencing. HMC3 was treated by 0, 10, 25, and 55 μmol· L⁻¹ permethrin for 72 h. The content of nitric oxide (NO) in the supernatant was detected using Griess reagent. The secretion level of interleukin-6 (IL-6) was detected by enzyme linked immunosorbent assay (ELISA). The mRNA expression levels of mitogen-activated protein kinase (MAPK) pathway (including MAPK1, MAPK8, and MAPK14), interleukin-1β (IL-1β), IL-6, and matrix metalloproteinase (MMP) families (including MMP1, MMP2, MMP3, and MMP9) were detected by qPCR. The protein expressions of phosphorylated p38 mitogen-activated protein kinase (p-p38), phosphorylated extracellular signal-regulated kinase (p-ERK), IL-1β, IL-6, and MMP1 were detected by Western blot. Results HMC3 was arrested in G2/M phase after 0, 10, 25, and 55 μmol·L⁻¹ permethrin treatment for 72 h, of which there was a statistically significant difference between the 55 μmol·L⁻¹ permethrin treatment group and the control group (P<0.01), and the mRNA expression of CDKN1A was up-regulated according to the qPCR (P<0.05). There was no statistically significant difference in the proportions of apoptosis between the groups (P＞0.05). The RNA sequencing showed that the differential genes were enriched in the MAPK pathway, and the mRNA expressions of MAPK1, MAPK8, and MAPK14 were up-regulated after the permethrin treatment at 55 μmol·L⁻¹ compared to the control group by qPCR (P<0.05). The Western blot revealed that, compared to the control group, the levels of p-p38 and p-ERK were increased after the 10 μmol·L⁻¹ permetrin treatment (P<0.05), the p-ERK level was increased after the 25 μmol·L⁻¹ permetrin treatment (P<0.05), and the p-p38 level was up-regulated after the 55 μmol·L⁻¹ permetrin treatment (P<0.05). The secretion of NO in the supernatant of HMC3 increased after permetrin treatment compared to the control group (P<0.05), the mRNA and protein expressions and the secretion of IL-6 showed an upward trend, the mRNA and protein expressions of IL-1β were up-regulated (P<0.05), and the mRNA and protein expressions of MMP1 were up-regulated in the 25 and 55 μmol·L⁻¹ permethrin groups (P<0.05). Conclusion Permethrin inhibits HMC3 cell proliferation in vitro, induces cell cycle arrest, activates MAPK pathway, and promotes the expression of inflammatory factors IL-1β and MMP1, which may be one of the mechanism of neurotoxicity induced by permethrin.

Nonalcoholic fatty liver disease(NAFLD),also known as metabolic associated fatty liver disease(MAFLD),is one of the most common chronic liver diseases characterized by the fat accumulation in the liver and hepatocellular damage.Patients with NAFLD can manifest as simple fatty liver or non-alcoholic steatohepatitis(NASH)in the early stage,and can progress to hepatic fibrosis,hepatic cirrhosis,hepatic fail-ure,and hepatic carcinoma in the late stage.NAFLD has become the most common chronic liver disease,af-fecting more than 30%of the population worldwide,posing a threat to human health that cannot be ignored.However,the current research on NAFLD is still incomplete,and there is no ideal medication for the treat-ment of NAFLD.The clinical management of NAFLD lacks unified standards and evidence-based evidence,and the multiple comorbidities bring challenges to the clinical management of NAFLD.This article was aimed to review the research progress in the clinical management of NAFLD,including the diagnosis and non-invasive examination methods,evaluation and commonly used tools,treatments methods,advantages and disadvanta-ges,so as to provide a reference for the clinical management of NAFLD.

Objective:To investigate the clinical efficacy of three-connections and four-screwings technique in the treatment of high double column acetabular fractures through a single ilioinguinal approach.Methods:A retrospective study was conducted to analyze the data of 42 patients who had been treated for high double column acetabular fractures from June 2017 to June 2020 at Trauma Ward 2, Department of Orthopedics and Traumatology, The First Hospital of Traditional Chinese Medicine of Changde. There were 19 males and 23 females with an age of (42.7±25.6) years. 29 injuries were due to a traffic accident, 12 ones to fall from a height, and one to fall. The time from injury to operation was (4.5±2.1) days. All the patients were treated by the three-connections and four-screwings technique through a single ilioinguinal approach. Briefly, the anterior column was connected and secured to the main bone using 3 routes, and the posterior column was attached and fixated to the anterior column reset using 2 or 3 of the 4 screwings. The operation time, intraoperative blood loss, fracture reduction quality, fracture healing time, hip function at the last follow-up and complications during the follow-up were recorded.Results:For this cohort, the operation time was (150.0±30.5) min, and intraoperative blood loss (300.0±50.0) mL. According to the Matta scale for postoperative acetabular fracture reduction, 34 cases were excellent, 6 cases good, and 2 cases acceptable, with an excellent and good rate of 95.2% (40/42). After operation one patient had fat liquefaction and wound exudation which responded to drainage and dressing change. The 42 patients were followed up for (15.0±3.4) months. All fractures healed after (11.0±2.0) months. By the modified Merle d'Aubigné & Postel scoring system, the hip function was evaluated at the last follow-up as excellent in 33 cases, as good in 6 cases, and as fair in 3 cases, yielding an excellent and good rate of 92.9% (39/42).Conclusions:In the treatment of high double column acetabular fractures, the three-connections and four-screwings technique through a single ilioinguinal approach can lead to fine reduction and rigid fixation by lag screw compression and neutralization plate protection. Consequently, early functional exercises can be performed to secure good therapeutic outcomes for the patients.
