OBJECTIVE To provide a scientific basis for the quality evaluation and clinical application of Qingwen hufei granules. METHODS Fourteen batches of Qingwen hufei granules were used as samples to establish high-performance liquid chromatography （HPLC） fingerprints using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine （2012 Edition）. The chromatographic peaks were identified and the similarity was evaluated. Cluster analysis （CA）， principal component analysis （PCA）， and orthogonal partial least squares-discriminant analysis （OPLS-DA） were used to conduct chemical pattern recognition analysis on the 14 batches of samples. Meanwhile， the contents of neochlorogenic acid （NGA）， chlorogenic acid （CHA）， cryptochlorogenic acid （CGA）， forsythoside A （FTA）， 3，5-O-dicaffeoylquinic acid （3，5-O- DA）， 4，5-O-dicaffeoylquinic acid （4，5-O-DA）， and angoroside C （AGC） in the samples were determined by HPLC. RESULTS The methodological investigation results of both the fingerprint and the content determination complied with the relevant requirements. Fourteen common peaks were indicated in the HPLC fingerprints of the 14 batches of samples， and 7 of them were identified [NGA （peak 2）， CHA （peak 3）， CGA （peak 5）， FTA （peak 11）， 3，5-O-DA （peak 12）， 4，5-O-DA （peak 13）， and AGC （peak 14）]； the similarity of each sample was greater than 0.94. The results of CA and PCA showed that the samples could be classified into 3 categories； the results of OPLS-DA indicated that peak 4 （unknown）， peak 11 （FTA）， peak 8 （unknown）， peak 9 （unknown）， and peak 1 （unknown） were the differential components. The content ranges of NGA， CHA， CGA， 3，5-O-DA， FTA， 4，5-O-DA and AGC in the 14 batches of samples were 0.210 4-0.458 7， 0.269 1-0.506 3， 0.228 1-0.461 1， 0.443 9-1.044 6， 0.066 7-0.155 7， 0.062 8-0.143 8， and 0.057 4-0.105 7 mg/g， respectively. CONCLUSIONS The HPLC fingerprint and multi-component content determination methods established in this study are efficient and reliable， and can be used for the quality evaluation of Qingwen hufei granules.

Objective To investigate the risk factors for postoperative recurrence and metastasis in patients with T1 stageⅢ/Ⅳ clear cell renal cell carcinoma(ccRCC), and to analyze the influence of surgical methods on prognosis, so as to provide prognostic evaluation and treatment guidance for clinical practice. Methods A retrospective analysis was conducted on 398 patients diagnosed with T1 stage Ⅲ/Ⅳ ccRCC who underwent either partial nephrectomy(PN)or radical nephrectomy(RN)at Jiangsu Province Hospital during Jan. 2008 and Sep. 2022. The patients were divided into recurrence group(n=49)and non-recurrence group(n=349)according to whether the tumor recurred during the follow-up period. The general, clinical data and prognosis were compared between the two groups. Univariate and multivariate Cox regression analyses were used to explore the factors influencing disease-free survival(DFS)and overall survival(OS)after surgery. Subgroup analysis using Kaplan-Meier curves was performed for T1a and T1b patients. Results During the median follow-up of 67(42, 98)months, the recurrence group was characterized by older age, larger tumor diameter, higher proportion of T1b stage, and more complex tumor anatomy. Univariate and multivariate Cox regression analyses showed that age ≥55 years and R.E.N.A.L. score ≥7 were independent risk factors for poorer DFS and OS(P＜0.05). Subgroup analysis revealed that PN or RN did not significantly affect DFS or OS in T1a patients and OS in T1b patients, while RN significantly improved DFS in T1b patients(P＜0.05). Conclusion Age ≥55 years and R.E.N.A.L. score ≥7 are independent risk factors for poor DFS and OS in highgrade T1 ccRCC patients. For T1b patients, RN may improve DFS.

Results Clear spots were obtained with good separation in TLC identification which was highly specific. The Saikosaponin-a at the range of 25.00-500.0 μg/ml was linear with peak area （r=0.999 9）, the average recovery rate was 97.00%, and RSD was 2.60%. Conclusion These methods was easy to operate with accurate results, with good specificity and reproducibility, which could be uesd for the quality control for Shugantongluo capsules.

Objective:To analyze Hepatitis B virus(HBV)drug resistance mutations in patients with chronic hepatitis B(CHB)infection who have undergone long-term monotherapy with Entecavir(ETV)and those receiving combination therapy with ETV and Lamivudine(LAM), and to explore the related factors affecting HBV drug resistance mutations.Methods:The study retrospectively analyzed patients with CHB, compensated cirrhosis, decompensated cirrhosis, and liver cancer who received long-term nucleotide analogue antiviral therapy at the Fifth Medical Center of PLA General Hospital from August 2012 to August 2019.The patients were divided into an ETV monotherapy group and a combined LAM+ETV therapy group.Chi-square tests, independent sample t-tests, and Wilcoxon rank-sum tests were used to compare the clinical baseline characteristics and HBV drug resistance mutation features between the two therapy groups.A multivariate logistic regression model was used to analyze the factors related to HBV drug resistance mutations. Results:A total of 533 patients were enrolled in this study, 357 in the ETV monotherapy group and 176 in the LAM+ETV group. The ETV monotherapy group had 122 (34.17%) patients with resistance mutations, while the LAM+ETV group had 126 (71.59%).In general, the difference in gene mutation rate between the two therapy groups was statistically significant( χ2=66.337, P<0.001). The median age and alanine aminotransferase levels of patients with drug resistance mutations in the two therapy groups were higher than those in the non-mutation group[( t=-4.743, P<0.001)/( Z=-4.809, P<0.001), ( Z=-2.667, P=0.007)/( Z=-2.001, P=0.045)].Age( OR=1.044, 95% CI:1.023-1.066), compensated cirrhosis( OR=2.163, 95% CI:1.193-3.922), liver cancer( OR=4.017, 95% CI:2.170-7.436) and the treatment regimen( OR=6.075, 95% CI:3.889-9.489) were associated with drug resistance gene mutations( P<0.001).The mutation rates in different stages of chronic liver disease(CHB, cirrhosis, and liver cancer)showed statistically significant( χ2=41.038, P<0.001; χ2=15.894, P<0.001).The overall mutation rates of ETV-related genes in the two therapy groups were 25.49% and 32.39%, respectively.Additionally, 10 mutation sites and 38 variant combinations were identified, containing five common combinations being rtL180M, rtM204V, rtS202G;rtL180M, rtM204V, rtT184A; rtL180M, rtM204V, rtT184L;rtM204I and rtL180M, rtM204V. Conclusion:In CHB patients undergoing long-term therapy, the rate of HBV resistance mutations is higher in those receiving ETV and LAM combination therapy than in those receiving ETV monotherapy.Monitoring older patients and those with cirrhosis or liver cancer is especially important for preventing resistance mutations.

OBJECTIVE: Glucocorticoid-induced osteoporosis (GIOP) is a common complication of prolonged glucocorticoid therapy. Chlorogenic acid (CGA), a polyphenol with antioxidant properties that is extracted from traditional Chinese medicines such as Eucommiae Cortex, has potential anti-osteoporotic activity. This study aimed to investigate the possible effects of CGA on GIOP in mice and murine long bone osteocyte Y4 (MLO-Y4) cells and explore the underlying molecular mechanisms. METHODS: The protective effects of CGA were initially evaluated in the GIOP mouse model induced by dexamethasone (Dex). The micro-computed tomography, hematoxylin-eosin staining, silver nitrate staining, and serum detection were used to assess the efficacy of CGA for improving bone formation in vivo. Then, network pharmacology analysis was used to predict the potential targets and molecular mechanisms underlying the therapeutic efficacy of CGA against GIOP. After that, 2',7'-dichlorofluorescein diacetate staining, flow cytometry, real-time quantitative reverse transcription polymerase chain reaction, and Western blotting were used to verify the mechanisms of CGA against GIOP in vitro. RESULTS: Animal experiments showed that CGA treatment effectively attenuated Dex-induced decreases in bone mass and strength and improved disrupted osteocyte morphology in mice. The protein-protein interaction analysis highlighted erb-b2 receptor tyrosine kinase (ERBB2), which is also known as human epidermal growth factor receptor 2 (HER2), caspase-3, kinase insert domain receptor, matrix metallopeptidase 9, matrix metallopeptidase 2, proto-oncogene tyrosine-protein kinase Src, and epidermal growth factor receptor as core targets. The Kyoto Encyclopedia of Genes and Genomes analysis revealed several significantly enriched pathways (P < 0.05), including the ERBB, phosphoinositide 3 kinase-AKT serine/threonine kinase 1 (AKT), and mechanistic target of rapamycin kinase (mTOR) pathways. Cellular experiments verified that CGA enhanced bone formation and promoted autophagy while inhibiting apoptosis in MLO-Y4 cells exposed to Dex, which was associated with the upregulated expression of HER2 and activation of the HER2/AKT/mTOR signaling pathway. CONCLUSION CGA exerted anti-osteoporotic effects against GIOP, partially through targeting osteocytes and modulating the HER2/AKT/mTOR signaling pathway.

Objective:To compare the efficacy and safety of the gastrointestinal endoscopic super minimally invasive surgery (eSMIS) and the laparoscopic minimally invasive procedure (LS) for the treatment of gastric glomus tumors(GGT).Methods:This study retrospectively included 15 patients with GGT who underwent eSMIS at the First Medical Center of Chinese PLA General Hospital from May 2014 to May 2024. Data on demographic characteristics, surgical indexes, efficacy evaluation indexes, postoperative medical disposition, health economics indexes and postoperative laboratory indexes were collected and analyzed, the patients were followed up for survival outcomes and the postoperative quality of life, efficacy and safety of the two groups were compared.Results:The amount of bleeding in the eSMIS group was lower than that in the LS group: 1.25 (0, 3.75) ml vs. 41.56 (10.00, 50.00) ml, and the surgical cost in the eSMIS group was lower than that in the LS group: 10 792.87 (8 424.90, 12 730.30) yuan vs. 21 773.06 (19 940.60, 24 843.10) yuan, there were statistical differences ( P<0.05). The surgical efficacy, postoperative laboratory indicators and medical treatment convenience between the two groups had no statistical differences ( P>0.05). Conclusions:In the choice of surgical procedures for the treatment of GGT, eSMIS is superior to LS in terms of bleeding and surgical cost, and not inferior to LS in other indicators. This suggested that the treatment of GGT with eSMIS is feasible, safe and effective.

Objective To investigate the expression of arginase Ⅱ(ArgⅡ)in kidney tissue of rats with diabetic nephropathy(DN)and its significance in the development of DN.Methods A total of 10 male SD rats were randomly divided into the control group and the model group,with 5 rats in each group.An rat model of DN was developed by feeding with high-sugar and high-fat diet combined with intra-peritoneal injection of low-dose streptozotocin(45 mg/kg),and they were sacrificed after 11 weeks of continued feeding.The body weight,and biochemical indexes of blood and urine of rats were determined.The right kidney was weighed and histopathological examination was performed.The pathological changes of kidney tissues and protein expression of ArgⅡ and CD68+were observed,and the immunofluores-cence double staining was used to observe the distribution and expression of ArgⅡand a marker of renal macrophage activation CD68+;the protein expression of ArgⅡ,NF-κB,TNF-α and IL-6 in kidney tissues was determined by Western blot.Results Compared with the control group,the ratio of kidney weight to body weight,24-hour urine volume,24-hour urine protein,fasting blood glucose,urea nitrogen and insulin level in the model group were significantly increased(P<0.05).The renal histopathology showed that the mesangial cells of the renal glomerular were necrotic with vascular dilatation,and the renal tubular epithelial cells were steatosis and congestion.Compared with the control group,the protein expression of ArgⅡ,CD68+,NF-κB,TNF-α and IL-6 in the kidney tissues of the model group were significantly increased(P<0.05).Immunofluorescence double staining demonstrated the co-expression of ArgⅡ and CD68+in renal tissue,and the fluorescence intensities of both ArgⅡ and CD68+in the model group were significantly stronger than those in the control group(P<0.01).Conclusion The expression of ArgⅡ is increased in DN,which may be participated in the occurrence of inflammatory lesions in DN.

Objective:To evaluate the cumulative live birth rate (CLBR) and cost-effectiveness of fixed versus adjusted follicle-stimulation hormone (FSH) dosages in infertile women with different ovarian responses during their first assisted reproductive technology (ART) cycle.Methods:A retrospective real-world cohort study was conducted on 5 419 infertile women who underwent their first ART treatment at the Department of Reproductive Medicine of the First Affiliated Hospital of Nanjing Medical University between January 2013 and December 2017. All patients received an individualized starting dosage of gonadotropin. Based on whether FSH dosages were adjusted during controlled ovarian stimulation (COS), patients were divided into fixed-dosage group ( n=2 061) and adjusted-dosage group ( n=3 358). Clinical outcomes and FSH cost-effectiveness were compared between the two groups across different ovarian response groups, with CLBR as the primary outcome. Propensity score matching (PSM) and multivariable logistic regression were used to adjust for potential confounders. Results:FSH dosage adjustments were found in 62.0% (3 358/5 419) of cycles during COS. After PSM, baseline characteristics were comparable between the two groups (all P>0.05). After adjusting for confounders using multivariable logistic regression, FSH dosage adjustment was not significantly associated with CLBR ( OR=1.06, 95% CI: 0.94-1.20, P=0.332). Compared with the adjusted-dosage group, the fixed-dosage group showed no significant differences in CLBR in poor-, normal-, and high-responder groups (all P>0.05). The incidence of ovarian hyperstimulation syndrome (OHSS) did not differ significantly between the two groups ( P>0.05). In poor-, normal-, and high-responder groups, the total FSH dosages in the fixed-dose group [1 350 (375, 1 825) U, 1 200 (375, 1 500) U and 525 (375, 1 128) U, respectively] were significantly lower than those in the adjusted-dose group [1 875 (1 425, 2 294) U, P=0.001; 1 425 (450, 1 875) U, P<0.001; 600 (375, 1 425) U, P=0.020]. Similarly, average FSH costs in different ovarian response groups in the fixed-dosage group [4 725.0 (1 312.5, 6 387.5) yuan, 4 200.0 (1 312.5, 5 250.0) yuan and 1 837.5 (1 312.5, 3 947.3) yuan, respectively] were significantly lower than those in the adjusted-dosage group [6 562.5 (4 987.5, 8 028.1) yuan, P=0.001; 4 987.5 (1 575.0, 6 562.5) yuan, P<0.001; 2 100.0 (1 312.5, 4 987.5) yuan, P=0.020]. For normal-responders, the FSH cost per high-quality embryo in the fixed-dosage group [1 365.0 (875.0, 2 537.5) yuan] was significantly lower than that in the adjusted-dosage group [2 056.3 (1 268.8, 3 412.5) yuan, P<0.001]. Conclusion:FSH dosage adjustment during COS is not associated with CLBR or the incidence of OHSS. However, the fixed-dose group exhibited lower total FSH dosages and costs across different ovarian response populations. In the context of ART being covered by medical insurance, fixed FSH dosage may represent a more cost-effective ovarian stimulation protocol.

OBJECTIVE To explore the clinical characteristics of bronchial asthma with secondary pulmonary infec-tions in children and compare the expressions of transcriptomes in peripheral blood between the bronchial asthma with secondary pulmonary infections and the bronchial asthma without the secondary pulmonary infections.METHODS The clinical data were collected from 425 children with bronchial asthma who were treated in respirato-ry medicine department of Children's Hospital of Anhui Province from Apr.2022 to Feb.2025 and were retrospec-tively analyzed.The enrolled children were divided into the infection group with 60 cases and the non-infection group with 365 cases according to the status of complication with pulmonary infections.The clinical characteristics were compared between the infection group and the non-infection group.The gene expression profile sequencing was carried out for peripheral blood mononuclear cells by transcriptome high throughput technology,and the bio-logical information was analyzed.RESULTS There were significant differences in course of asthma,frequencies times of acute attack,complication with nasosinusitis or allergic rhinitis,standardized use of antibiotics and intra-venous use of glucocorticoids between the two groups of children(P＜0.05).Totally 60 children had secondary pulmonary infections,with the infection rate 14.12％.Totally 73 strains of pathogens were isolated,43.84％of which were gram-positive bacteria,and 56.16％were gram-negative bacteria.As compared with the non-infection group,there were 1578 genes with the changed expression in the infection group,and the expressions of the genes such as nuclear factor κB were upregulated.The differentially expressed genes were primarily enriched in immuno-regulation-related pathways,including proinflammatory factor signal transduction,interacted networks of cyto-kines and its receptors,T lymphocyte activation signal transduction and other biological processes.CONCLUSION The specific clinical characteristics and abnormal immune pathways may jointly result in the pulmonary infec-tions in children with the asthma and provide theoretical bases for early identification of the children at high risk of pneumonia and targeted intervention.

Objectives:To analyze the disease burden and trends of ischemic stroke attributable to major metabolic risk factors in China from 1990 to 2021,and provide a basis for disease prevention and management.Methods:Based on the Global Burden of Disease(GBD)2021 data,we compared the age-standardized mortality rate(ASMR)and age-standardized disability-adjusted life year rate(ASDR)of ischemic stroke attributable to major metabolic risk factors(including overweight/obesity,hypertension,elevated low-density lipoprotein cholesterol,low bone density,hyperglycemia,and impaired renal function)in China and globally,and estimated their time trends through estimated annual percentage change(EAPC).We also analyzed the number of deaths,mortality rate,disability adjusted life year(DALY),and DALY rate of ischemic stroke attributable to major metabolic risk factors in China from 1990 to 2021,and compared the epidemiological differences among different gender and age groups.Results:From 1990 to 2021,the disease burden of ischemic stroke attributable to major metabolic risk factors in China showed a slight upward trend(1990 to 2005)and then gradually decreased,with a relatively small overall decline.,while the global disease burden showed a decreasing trend.In 2021,the ASMR and ASDR of ischemic stroke attributable to major metabolic risk factors in China were 48.11/100 000 and 898.35/100 000(EAPC[95%CI]were-0.24%[-1.13%to 0.66%]and-0.25%[-1.00%to 0.51%]),respectively,both higher than the global average levels(33.96/100 000 and 651.46/100 000,EAPC[95%CI]were-1.75%[-2.03%to 1.47%]and-1.49%[-1.74%to-1.23%],respectively).Compared with 1990,the actual mortality rate and DALY rate of ischemic stroke attributable to major metabolic risk factors in China increased by 139.60%and 110.53%respectively in 2021.There are gender differences in the disease burden of ischemic stroke attributable to major metabolic risk factors in China,with significantly higher death numbers,mortality rates,DALY,and DALY rates in males compared to females.At the age level,DALY and DALY rates were both higher in individuals aged 15-49,DALY increased but DALY rates decreased in individuals aged 50-69.DALY surged in individuals aged 70 and above,male DALY rates showed increasing trend and female DALY rates showed slightly decreasing trend.Conclusions:The disease burden of ischemic stroke in China is significantly affected by metabolic risk factors.Although prevention and control have achieved certain positive results,the overall disease burden in China is higher than that of the world,and precise intervention strategies need to be developed for different genders and ages in China.
