To standardize the clinical application of oral Chinese patent medicines （CPMs）， and address the safety issues arising from their dosage form characteristics， irrational clinical use， and the lack of targeted pharmacovigilance systems， the China Association of Chinese Medicine organized the formulation and release of Pharmacovigilance Guidelines for Clinical Application of Oral Chinese Patent Medicines， aiming to inform the safe clinical use of oral CPMs and related pharmacovigilance work. According to the principles of GB/T1.1—2020 and the Drug Administration Law of the People's Republic of China （2019 revision）， the Institute of Basic Research in Clinical Medicine， China Academy of Chinese Medical Sciences， led a drafting group comprising 18 institutions. After multiple rounds of expert interviews， literature retrieval， evidence screening， and extensive solicitation of opinions， the Guidelines were registered internationally. Systematic standardization focused on safety monitoring， risk identification， assessment， control， and other aspects. The Guidelines clarified the characteristics of oral CPMs in terms of safety monitoring， known risks， and potential risks， compared to non-oral CPMs. Then， risk control measures were proposed， including medication in special populations and irrational medication. As a special guideline for pharmacovigilance in the clinical application of oral CPMs， the Guidelines systematically construct a technical system in line with the characteristics of traditional Chinese medicine （TCM）， which is essential for improving the clinical safety management of oral CPMs and provides an important reference for medical institutions， pharmaceutical manufacturers， and regulatory authorities.

Objective To investigate the impact of pomegranate peel polyphenols(PPP)on the malignant biological behavior of colon cancer cells through modulation of the miR-138-5p/hypoxia-inducible factor-1α(HIF-1α)pathway.Methods Quantitative real-time PCR(qRT-PCR)was employed to measure the expression levels of miR-138-5p and HIF-1α mRNA in the normal colon epithelial cell line FHC and three colorectal cancer cell lines:SW480,HCT116,and Caco-2.SW480 cells were divided into six groups:a blank control group,a negative control(mimics NC)group,a miR-138-5p mimics group,three different concentrations of PPP treatment groups(0.5 mg/mL,1 mg/mL,and 2 mg/mL),a PPP+inhibitor NC group at 2 mg/mL,and a PPP+miR-138-5p inhibitor group at 2 mg/mL.The effects on cell proliferation,invasion,and migration,as well as changes in apoptosis and related proteins including B-cell lymphoma 2(Bcl-2),migration invasion enhancer 1(MIEN1),and Cyclin D1,were evaluated separately.Additionally,the targeting relationship between miR-138-5p and HIF-1α was validated.The expression levels of miR-138-5p,HIF-1α mRNA,and protein were assessed in each experimental group.Results The expression levels of miR-138-5p were highest in FHC cells and lowest in SW 480 cells,while the expression levels of HIF-1α mRNA showed an opposite trend,being lowest in FHC cells and highest in SW 480 cells(P<0.05).Compared with the control group,different concentrations of PPP significantly promoted cell apoptosis,upregulated miR-138-5p expression,inhibited cell proliferation,invasion,and migration,and downregulated the expression of HIF-1α mRNA,Bcl-2,MIEN1,CyclinD1,and HIF-1α protein,with significant differences between groups(P<0.05).Compared with the mimics NC group,the miR-138-5p mimics group significantly enhanced cell apoptosis,upregulated miR-138-5p expression,inhibited cell proliferation,invasion,and migration,and downregulated the expression of HIF-1α mRNA,Bcl-2,MIEN1,CyclinD1,and HIF-1α protein(P<0.05).Compared with the 2 mg/mL PPP+inhibitor NC group,the 2 mg/mL PPP+miR-138-5p inhibitor group significantly suppressed cell apoptosis,downregulated miR-138-5p expression,promoted cell proliferation,invasion,and migration,and upregulated the expression of HIF-1α mRNA,Bcl-2,MIEN1,CyclinD1,and HIF-1α protein(P<0.05).These results indicate a targeted relationship between miR-138-5p and HIF-1α(P<0.05).Conclusion PPP inhibits the malignant biological behavior of colon cancer cells through upregulation of the miR-138-5p/HIF-1α pathway.

Objective:To combine the conventional audiometric curves and extended high frequency audiometric curves of patients with sensorineural deafness to form a full-frequency audiometric curve and to perform typing, so as to comprehensively understand the hearing status of patients with sensorineural deafness.Methods:This study was a cross-sectional study. The study subjects included 249 patients with sensorineural hearing loss who visited the Otolaryngology-Head and Neck Surgery outpatient clinic of the PLA General Hospital between July 2019 and December 2020. Among them, 146 were male and 103 were female, aged 11 to 80 years. The cases included 123 with mild hearing loss, 70 with moderate hearing loss, 32 with moderately severe hearing loss, 17 with severe hearing loss, 6 with profound hearing loss, and 1 with total deafness. According to the national standard GB/T16403-1996, conventional pure-tone audiometry (125-8 000 Hz) was performed on the 249 patients with sensorineural hearing loss to obtain their conventional-frequency hearing curves, which were then classified. Extended high-frequency pure-tone threshold testing (9 000-20 000 Hz) was conducted using extended high-frequency headphones, specifically including eight frequencies: 9 000, 10 000, 11 200, 12 500, 14 000, 16 000, 18 000, and 20 000 Hz. Ultimately, the full-frequency hearing curves (125-20 000 Hz) of each patient were obtained. The K-means clustering analysis method was used to classify the hearing curves based on their characteristics, and the results of the K-means clustering analysis were partially adjusted through manual screening.Results:The conventional hearing curves of all 249 patients were consistent with sensorineural hearing loss. The detection rates for extended high frequencies (9 000, 10 000, 11 200, 12 500, 14 000, 16 000, 18 000, and 20 000 Hz) were 96.79% (241/249), 94.38% (235/249), 87.95% (219/249), 78.31% (195/249), 65.46% (163/249), 22.09% (55/249), 10.84% (27/249), and 0.80% (2/249), respectively. The conventional-frequency hearing curves of the patients could be classified into the following types: low-frequency descending type (50/249, 20.08%), conventional-frequency steep descending type (78/249, 31.33%), conventional-frequency gradual descending type (58/249, 23.29%), conventional-frequency flat type (25/249, 10.04%), conventional-frequency 4 000 Hz notch type (30/249, 12.05%), and other types (8/249, 3.21%). By incorporating extended high-frequency hearing data, the full-frequency hearing curves of 235 patients were further classified into the following types based on different characteristics: full-frequency hill type (32/235, 13.62%), full-frequency ascending type (28/235, 11.91%), full-frequency 8 000 Hz notch type (14/235, 5.96%), full-frequency steep descending type (82/235, 34.89%), full-frequency gradual descending type (34/235, 14.47%), full-frequency shoulder-raising type (7/235, 2.98%), full-frequency shoulder-dropping type (25/235, 10.64%), full-frequency flat type (8/235, 3.40%), and other full-frequency types (5/235, 2.13%).Conclusions:Compared to the classification based on conventional-frequency hearing curves, the full-frequency hearing curves of patients with sensorineural hearing loss provide a more comprehensive representation of their overall hearing status. Patients with the same conventional-frequency hearing curve classification may exhibit different full-frequency hearing curve types, suggesting potential differences in the location and extent of pathological damage within their auditory systems.

Objective:To investigate gait alterations in patients with rheumatoid arthritis (RA) complicated with knee joint damage and to explore the potential of using gait analysis to evaluate the effectiveness of precision medical or surgical treatments in RA patients, serving as a reference for future gait-related research.Methods:A total of 45 patients with cumulative knee joint RA and 45 healthy control subjects were recruited from May 2021 to May 2022. Gait analysis and scale scoring were performed to compare gait changes between the two groups. Statistical tests including t-test, Mann-Whitney U, and Pearson Chi-square were used to assess group differences. Results:Compared with the control group, the objective gait indexes of the knee involvement in patients with rheumatoid arthritis were double support time [(523±127)ms and (333±45)ms, t=-9.48, P<0.001], total support time [(904±137) ms and (678±101)ms, t=-8.90, P<0.001], step length [(635±81) ms and (548±56) ms, t=-5.91, P<0.001], walking cycle [(1 273±169) ms and (1 075±104) ms, t=-4.76, P<0.001], the proportion of single support cycle (0.298±0.037 and 0.334±0.015, t=6.06, P<0.001), the proportion of double support cycle (0.408±0.069 and 0.309±0.021, t=-7.90, P<0.001), total support period ratio (0.709±0.035 and 0.628±0.041, t=-10.01, P<0.001), step length [(40±5)cm and (52±4)cm, t=9.02, P<0.001], step length [(77±11)cm and (104±8)cm, t=12.71, P<0.001] and the pace [(0.708±0.168) m/s and (1.050±0.192) m/s, t=8.98, P<0.001] were significantly different. Conclusion:Gait analysis can be utilized for the quantitative evaluation of patients with rheumatoid arthritis (RA), complicated with knee darnage, enabling objective quantification of assessment indicators and offering novel ideas and methodologies for diagnosing and treating of patients with RA.

Osteoporosis is a systemic disease characterized by imbalanced bone metabolism and destruction of bone microstructure, with reduced bone density, decreased bone quality, and significantly increased risk of fracture as its hallmarks. At present, osteoporosis is primarily diagnosed through bone density measurement. However, this method has low sensitivity and is challenging for the early diagnosis of osteoporosis. We analyzed osteoporosis-related metabolomics studies based on blood, urine, and fecal samples, as well as the application of multi-omics approaches in elucidating its pathogenesis. Evidence suggests that metabolomics can detect metabolic alterations prior to measurable changes in bone mineral density, offering promising avenues for early osteoporosis detection. Blood-based metabolomics studies indicate that amino acid metabolism dysregulation is a key feature of osteoporosis. Specifically, glycine, glutamine, lysine, and hydroxyproline exhibit negative correlations with bone mineral density, whereas tryptophan, branched-chain amino acids, and arginine show positive associations. Lipid metabolism disturbances are characterized by increased levels of phosphatidylcholine, phosphatidylethanolamine, and triglycerides, alongside decreased levels of sphingomyelin and carnitine. Fecal metabolomics studies highlight the significance of the "gut-bone axis" in osteoporosis, where gut microbiota dysbiosis influences bone metabolism through modulation of arginine and proline metabolism and aminoacyl-tRNA biosynthesis pathways. Multi-omics approaches integrate metabolomics, genomics, proteomics, and other omics data to provide a more comprehensive understanding of osteoporosis' molecular mechanisms, enabling the identification of key biomarkers and therapeutic targets. Metabolomics holds considerable potential for early diagnosis, while multi-omics integration offers novel insights into the complex pathophysiological mechanisms underlying osteoporosis. As detection technologies and analytical methods continue to advance, omics-based strategies are expected to play a pivotal role in the development of precision medicine for osteoporosis.

Objective:To understand the clinical manifestations, laboratory characteristics, and treatment of Staphylococcus aureus ( Sa) infection in children, and explore the predictive value of lymphocyte count, neutrophil to lymphocyte ratio(NLR), and high-sensitivity C-reactive protein to albumin ratio(CAR) in patient with secondary bloodstream infection(BSI). Methods:A retrospective analysis was conducted on 72 children with Sa infection admitted to the Nanchong Hospital of Beijing Anzhen Hospital Affiliated to Capital Medical University from January 2020 to April 2024. Clinical data including basic information, drug resistance, antibiotic treatment were collected. Differences in laboratory test results and inflammatory indicators were analyzed. The influencing factors of Staphylococcus aureus bacteraemia(SAB) in pediatric patients were analyzed using univariate/multivariate Logistic regression and correlation analysis. The predictive value was analyzed by receiver operating characteristic curve (ROC) and area under curve (AUC). Results:Seventy-two patients were selected, of whom 60 (83.33%) had skin and soft tissue infections (SSTIs), mainly community-associated Staphylococcus aureus(CA-SA)(50 cases), including 16 community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) cases (32.00%, 16/50). The detection rate of MRSA was 37.50% (27/72). The resistance rates of Sa to penicillin, clindamycin, and erythromycin were 97.22%(70/72), 69.44%(50/72), and 69.44%(50/72), respectively. Compared with the SSTIs group, the levels of lymphocyte count in children with bone and joint infections were significantly lower, while NLR and CAR levels were higher ( P<0.05). Fourteen patients had secondary SAB. In the secondary SAB group, lymphocyte counts were lower, while inflammatory indicators (NLR, CAR), and D-dimer were higher. CAR and NLR are positively correlated with the occurrence of bloodstream infections ( P<0.05). CAR ( OR=4.866, 95% CI: 1.37-17.25) and NLR ( OR=1.293, 95% CI: 1.032-1.620) were independent risk factors for secondary bloodstream infection, and ROC curve results showed that the combination of the two indicators had a higher sensitivity (0.929) and AUC (0.909) than individual testing. After undergoing effective treatment, the levels of CAR and NLR in the children in the secondary SAB group were significantly reduced. Wound infection patients underwent debridement treatment in 38 cases (52.78%, 38/72), while antibiotic treatment still primarily used first- and second-generation cephalosporins. For patients with secondary bloodstream infection, vancomycin was the first choice. Conclusions:Children′s wound infections with Sa primarily involve skin and soft tissue infections, commonly seen in CA-SA. NLR and CAR are independent risk factors for children with secondary bloodstream infection, and their combined detection has certain value for early diagnosis.

Objective:To identify the relevant factors for the first-course remission of acute myeloid leukemia (AML) and to develop a predictive model as well as assess its predictive capability.Methods:Clinical data of 749 patients newly diagnosed with AML admitted to the Department of Hematology, the First Affiliated Hospital, Zhejiang University, School of Medicine from January 1, 2019, to April 30, 2023, were collected and randomly divided into training and validation sets. Multivariate logistic regression analysis was conducted to determine variables associated with complete remission in the first course of induction therapy, and a predictive model was established based on these variables. The receiver operating characteristic (ROC) curve of the predictive model was plotted, and the area under the curve (AUC) was calculated.Results:The indicators predicting the first remission course included peripheral blood white blood cell count during onset, CBF::MYH11 fusion gene, CEBPA bZIP region mutation, myelodysplastic syndrome-related gene mutation, and induction chemotherapy regimen selection as independent factors for the first remission course. The model’s area under the training and validation curves was 0.738 (95% CI: 0.696-0.780) and 0.726 (95% CI: 0.650-0.801), respectively. The Hosmer-Lemeshow test results yielded P-values of 0.993 and 0.335, respectively. Conclusion:In this study, the developed model demonstrates a strong predictive capability for the efficacy of the first course of patients with AML, providing valuable guidance to clinicians in assessing patient prognosis and selecting appropriate treatment strategies.

Objective To discuss the effect of interleukin-17A(IL-17A)and transforming growth factor-β1(TGF-β1)on the benign tracheal stenosis after tracheal injury in experimental dogs.Methods The trachea stenosis model of healthy Beagle dogs was established by burning the middle part of trachea with electric snare under bronchoscopy guidance.A total of 21 dogs were divided into normal group(n=3,receiving normal feeding),molding group(n=12,after airway modeling every 3 dogs were sacrificed each week for 4 weeks),IL-17A suppression group(n=3,receiving Secukinumab after airway modeling),and IL-17A inhibitor+TGF-β1 inhibitor group(n=3,receiving Secukinumab and SB43154 after airway modeling).Bronchoscopy and CT scan were performed once a week,and the stenosis degree was calculated.RT-qPCR,immunohistochemistry,and HE staining of the obtained tracheal tissues were performed.Results Within 1-4 weeks after molding,in module-making dogs the degree of stenosis of the injured trachea gradually increased,and the expressions of ECM-related proteins,TGF-β1 and IL-17A were up-regulated.After treatment with IL-17A inhibitors,the inflammatory infiltration and granulation tissue hyperplasia were reduced and the early tracheal stenosis was improved(P＜0.05).The combination use of IL-17A inhibitor and TGF-β1 inhibitor had a better remission effect(P＜0.05).Conclusion IL-17A and TGF-β1 may synergistically affect the formation of tracheal stenosis.

Objective To analyze the diagnostic value of serum biomarkers in patients with pulmonary tuberculosis complicated by invasive pulmonary aspergillosis.Methods A retrospective collection of laboratory test results,including blood analysis,liver function,lymphocyte counts,and cytokine levels,from 54 patients diagnosed with pulmonary tuberculosis and invasive pulmonary aspergillosis admitted to the Third People's Hospital of Kunming between January 2021 and May 2024.Additionally,70 patients with simple pulmonary tuberculosis and 50 healthy individuals were collected as control groups to compare serum biomarker levels across the three groups and analyze relevant factors and diagnostic value for pulmonary tuberculosis patients with invasive pulmonary aspergillosis.Results Among different age groups,the incidence of pulmonary tuberculosis with invasive pulmonary aspergillosis was 29 cases(53.7％)in youth,15 cases(27.8％)in middle age,and 10 cases(18.5％)in the elderly.In terms of gender distribution,there were 41 males(75.9％)and 13 females(24.1％).The serum levels of CRP(6.85[2.10,27.0])ng/L,PCT(0.05[0.05,0.15])ng/mL,RBC(4.55±0.65)× 1012/L,Hb(129.13±19.10)g/L,TP(66.23±6.82)g/L,ALB(37.03±4.77)g/L,and CHOL(4.30[3.71,4.91])mmol/L in the invasive pulmonary aspergillosis group showed no significant difference compared to the simple tuberculosis group and healthy control group(P＞0.05).The levels of CD3+T,CD4+T,and CD8+T in the invasive pulmonary aspergillosis group were significantly lower than those in the simple tuberculosis group and healthy control group(P＜0.05).The levels of IL-2,IL-4,IL-5,IL-8,IL-10,IL-12p70,IFN-α,and TNF-α in the invasive pulmonary aspergillosis group were significantly higher than those in the healthy control group(P＜0.05);IL-8,IL-12p70,and IFN-α were also higher compared to the simple tuberculosis group,with statistical significance(P＜0.05).Conclusion The population with pulmonary tuberculosis complicated by invasive pulmonary aspergillosis is predominantly male and younger.The serum indicators of infection severity and nutritional status in these patients are similar to those with simple tuberculosis and lack specificity;however,their immune function is significantly lower than that of simple tuberculosis patients.Multiple cytokines are elevated,particularly IL-8,IL-12p70,and IFN-α,which can aid in the differential diagnosis of pulmonary tuberculosis infection.
