OBJECTIVE To investigate the mechanism by which Shenfukang capsule （SFK） ameliorates renal interstitial fibrosis （RIF） by regulating macrophage-fibroblast crosstalk via the signal transducer and activator of transcription 3 （STAT3）/Yes-associated protein （YAP） pathway. METHODS RAW264.7 macrophages were induced to polarize with transforming growth factor-β 1 （TGF-β 1 ）. Subsequently， a non-contact co-culture system of macrophages with renal fibroblasts NRK-49F， as well as a non-contact co-culture system of macrophages with YAP-knockdown renal fibroblasts， were established. Cells were treated with low， medium， and high concentrations （4， 8， 16 μg/mL） of SFK， as well as a STAT3 inhibitor （STAT3-I，1.64 μg/mL） and losartan potassium tablets （positive control， 0.28 μg/mL）， for 48 h. After intervention， the protein and mRNA expression levels of CD86， CD163， and STAT3 in macrophages， as well as CD86， F4/80， and STAT3 mRNA， were detected. In co-cultured renal fibroblasts， the protein and mRNA expression levels of α -smooth muscle actin （ α -SMA）， Vimentin， collagen type Ⅰ （Col-Ⅰ）， matrix metalloproteinase-1 （MMP-1）， and YAP were detected. In co-cultured YAP-knockdown renal fibroblasts， the protein and mRNA expression levels of α -SMA， Vimentin， and MMP-1 were also detected. RESULTS Following TGF-β 1 induction， the protein expression levels of CD86， CD163， and STAT3， as well as the mRNA expression levels of CD86， F4/80， and STAT3 in macrophages were significantly increased （ P ＜0.05）. The conditioned medium from polarized macrophages activated renal fibroblasts， as evidenced by significantly increased protein and mRNA expression levels of α -SMA， Vimentin， Col-Ⅰ， and YAP， and significantly decreased protein and mRNA expression levels of MMP-1 in renal fibroblasts （ P ＜0.05）. Treatment with SFK and STAT3-I reversed the changes in the above indicators， with the medium concentration SFK group showing stronge r effects on some indicators than the low and high concentration groups. In the non-contact co-culture experiment of macrophages and YAP-knockdown renal fibroblasts， there were no statistically significant differences in the protein and mRNA expression of α-SMA， Vimentin， and MMP-1 among the groups. CONCLUSIONS SFK can inhibit macrophage-renal fibroblast crosstalk by blocking the STAT3/YAP pathway， thereby delaying the progression of RIF.

As the first defense of respiratory system,airway epi-thelial cells(AECs)play an important role in separating the re-spiratory internal and external environment.They are essential for the natural immune function.Small airway lesions are an im-portant early pathology of chronic obstructive pulmonary disease(COPD),when AECs are exposed to harmful particles or gases for a long time,the epithelial barrier is damaged,and the signa-ling pathways which involved in differentiation,repair,and in-flammatory are disordered,resulting in epithelial cell cycle stag-nation and accelerated aging.A number of studies have sugges-ted that AECs of COPD patients express high levels of aging markers,suggesting that senescence of AECs is closely related to COPD.This review discusses the potential mechanisms of AECs senescence in COPD,the impact of AECs senescence on the de-velopment and severity of the disease,and highlights potential targets for modulating cellular senescence in airway epithelium as a therapeutic approach in COPD.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

OBJECTIVE To analyze the clinical distribution characteristics and drug resistance of Enterobacter cloa-cae in Gansu Province from 2019 to 2023,providing reference for the prevention and control of E.cloacae infec-tions in this region.METHODS Data on the distribution and drug resistance of E.cloacae from hospitals in mem-ber units of the Gansu Antimicrobial Surveillance Network between 2019 and 2023 were collected.In vitro drug susceptibility testing was performed by the Kirby-Bauer disk diffusion(K-B)method,minimum inhibitory con-centration method,and fully automated instrumentation,followed by analysis of the susceptibility results.RESULTS From 2019 to 2023,a total of 402 490 bacterial strains were isolated and cultured in Gansu Province,including 17 417 strains of E.cloacae,with a detection rate of 4.33％.The bacteria were primarily iso-lated from sputum specimens(62.81％),followed by urine(7.37％)and wound pus specimens(6.07％).The de-partmental distribution was dominated by internal medicine(44.96％)and surgery(28.50％).The highest detec-tion rate was observed in the adult group(15-65 years,45.79％).E.cloacae exhibited varying degrees of resist-ance to over 20 antibacterial drugs,but the overall drug resistance rate showed a declining trend(P＜0.05).The highest drug resistance rate was observed for cefazolin(96.40％-98.38％),while the lowest was for tigecycline(0.44％—2.92％).Carbapenem-resistant E.cloacae demonstrated an increasing trend in drug resistance rates,with imipenem resistance ranging from 2.79％to 3.71％(P=0.044)and meropenem resistance ranging from 1.29％to 3.41％(P＜0.05).CONCLUSIONS The isolation rate of E.cloacae in Gansu Province remains stable,with a declining trend in drug resistance to multiple antibacterial drugs.However,the increasing drug resistance to carbapenems warrants attention.

AIM:To evaluate the pharmacokinet-ics(PK)and pharmacodynamics(PD)of two recom-binant human insulin injection by euglycemic clamp technology in healthy male subjects after a single subcutaneous injection.METHODS:We con-ducted a randomized,open-label,single dose,two period,crossover study.A total of 24 healthy male subjects were enrolled and randomized to receive single subcutaneous doses(0.2 U/kg)of the investi-gational products every period.The PK and PD characteristics were assessed by euglycemic clamp up to 14 hours after dosing.RESULTS:Euglycemic clamp technique was successfully established.C-peptide levels detected at each time point before and after administration indicated that endoge-nous insulin secretion was inhibited in the two groups after administration.The geometric mean ratio of Cmax and AUC0-tand 90％confidence interval(CI)of test preparation and reference preparation under fasting condition were in the range of 80.00％-125.00％.CONCLUSION:The human insulin produced by KP Biotech demonstrated similarity to the reference preparation Humulin? in PK and PD characteristics in healthy Chinese subjects.

Objective:To evaluate the efficacy and safety of the pegaspargase, etoposide, methotrexate, and dexamethasone (PEMD) regimen in patients with early-stage nonupper respiratory digestive tract or advanced extranodal natural killer/T-cell lymphoma (ENKTL) .Methods:This retrospective analysis included 38 patients with newly diagnosed early-stage non-upper respiratory digestive tract or advanced ENKTL who received PEMD regimen for induction chemotherapy at the First Affiliated Hospital of Nanjing Medical University from January 2016 to December 2022. Survival outcomes and prognostic factors were examined by Kaplan-Meier, and the Log-rank test was used to compare survival.Results:The study population had a median age of 48 years (range, 26-72 years) and included 30 males (78.9%) and 8 females (21.1%). 7 patients’ age >60 years (18.4%). The Eastern Cooperative Oncology Group (ECOG) performance score was >1 in 7 patients (18.4%) ; 20 patients (52.6%) had elevated lactate dehydrogenase levels; and 37 patients (97.4%) exhibited extranodal involvement. Using the Ann Arbor staging system, 37 patients (97.4%) were classified as stage Ⅲ-Ⅳ. The median number of treatment cycles was 5 (1-6), and the median follow-up duration was 60 months (24 - 101 months). Interim efficacy assessment revealed an overall response rate of 52.7%. At 2 and 4 years, the progression-free survival (PFS) rates were 34.2% (95% CI 22.0%-53.2%) and 25.5% (95% CI 14.7%-44.4%), respectively, and the overall survival rates were 50.0% (95% CI 36.4%-68.7%) and 45.5% (95% CI 31.4%-65.7%), respectively. The risk factors for worse PFS were ECOG performance score >1 [ HR=3.711 (95% CI 1.494-9.218), P=0.005]; bone marrow infiltration [ HR=2.251 (95% CI 1.026 - 4.938), P=0.043]; and Prognostic Index for Natural Killer/T-Cell Lymphoma score of 3 - 5 [ HR=2.350 (95% CI 1.009 - 5.476), P=0.048]. Multivariate analysis identified ECOG performance score >1 as an independent risk factor for PFS [ HR=7.971 (95% CI 2.222 - 28.591), P=0.001]. The main adverse effect was anemia in 31 patients (81.6%) . Conclusion:The PEMD regimen was safe and effective for patients with newly diagnosed early-stage non-upper respiratory digestive tract or advanced ENKTL.

Objective:To explore the genetic etiology of fetal skeletal dysplasia using whole exome sequencing (WES) and copy number variation sequencing (CNV-seq) techniques, and the feasibility of using WES as the first-tier method for such fetuses.Methods:Seventy four fetuses with skeletal dysplasia detected by prenatal ultrasound at the Genetic Testing Center of the Women and Children′s Hospital Affiliated to Qingdao University from January 2020 to August 2024 were selected as the study subjects. Fetal muscle and peripheral blood samples of the pregnant women and their spouses were collected and subjected to WES analysis. CNV-seq was carried out on all fetal muscle tissue samples. And the results were compared with the CNVs indicated by WES. Genetic etiologies were analyzed across different subtypes of skeletal dysplasia. And the feasibility of using WES as the first-tier genetic test for similar fetuses was assessed, in addition with a systematic cost-effectiveness analysis. This study was approved by the Medical Ethics Committee of the Hospital (Ethics No.: QFELL-YJ-2024-201).Results:A total of 50 fetuses were diagnosed, which yielded a diagnostic rate of 67.57%. These included 6 chromosomal aneuploidies, 4 chromosomal CNVs and 40 monogenic disorders. The monogenic diseases had involved 46 variant sites in 23 pathogenic genes, among which 12 were unreported previously, including MYH3: c. 735T>C, ALPL: c. 1324C>T, NEK9: c. 1973G>A, MAGEL2: c. 2024_2025del, LMBR1: c. 423+ 4914A>C, NEB: c. 21273_21276del, COL1A1: c. 2651G>C and c. 2758G>C, ASPM: c. 2473delinsGA, TBX5: c. 704G>A, DYNC2H1: c. 10893del, and DYNC2I2: c. 1270C>T. Substantial concordance was reached between WES-derived CNV calls and CNV-seq findings. No clinically significant CNV was exclusively detected by CNV-seq. Cost-effectiveness modeling demonstrated that implementing WES as the first-tier genetic testing method could reduce the total expenditure when WES unit cost remained below 6.4 folds that of the CNV-seq. Conclusion:Genetic variants including single nucleotide variations (SNV) of monogenic disorders, chromosomal aneuploidies and genomic CNVs are important causes for fetal skeletal dysplasia. WES is an accurate and efficient method for analyzing the etiology of fetal skeletal dysplasia, particularly in those with a family history of similar phenotype or maternal history of adverse pregnancies.
