ObjectiveTo explore the clinical safety of Feilike Mixture （FLK） in the real world. MethodsThe safety of all children who received FLK from 29 institutions in 12 provinces between January 21，2021 and December 25，2021 was evaluated through prospective centralized surveillance and a nested case control study. ResultsA total of 3 035 juveniles were included. There were 29 research centers involved，which are distributed across 12 provinces，including one traditional Chinese medicine （TCM） hospital and 28 general hospitals. The average age among the juveniles was （4.77±3.56） years old，and the average weight was （21.81±12.97） kg. Among them，119 cases （3.92%） of juveniles had a history of allergies. Acute bronchitis was the main diagnosis for juveniles，with 1 656 cases （54.46%）. FLK was first used in 2 016 cases （66.43%），and 142 juvenile patients had special dosages，accounting for 4.68%. Among them，92 adverse drug reactions （ADRs） occurred，including 73 cases of gastrointestinal system disorders，10 cases of metabolic and nutritional disorders，eight cases of skin and subcutaneous tissue diseases，two cases of vascular and lymphatic disorders，and one case of systemic diseases and various reactions at the administration site. The manifestations of ADRs were mainly diarrhea，stool discoloration，and vomiting，and no serious ADRs occurred. The results of multi-factor analysis indicated that special dosages （the use of FLK）［odds ratio （OR） of 2.642， 95% confidence interval （CI） of 1.105-6.323］，combined administration： spleen aminopeptide （OR of 4.978， 95%CI of 1.200-20.655），and reason for combined administration： anti-infection （OR of 1.814， 95%CI of 1.071-3.075） were the risk factors for ADRs caused by FLK. Conclusion92 ADRs occurred among 3 035 juveniles using FLK. The incidence of ADRs caused by FLK was 3.03%，and the severity was mainly mild or moderate. Generally，the prognosis was favorable after symptomatic treatment such as drug withdrawal or dosage reduction，suggesting that FLK has good clinical safety.

Practice-oriented education is an important link in cultivating qualified builders and reliable successors of socialism， and it is particularly important for cultivating high-quality talents in traditional Chinese medicine （TCM）. Practice-oriented education is a vital part in improving college students’ ideological and political literacy， an important measure for TCM colleges and universities to promote the inheritance and innovation of TCM culture， and a significant pathway to cultivate high-quality TCM talents. The prominent issues of practice-oriented education in TCM colleges and universities are that the small ideological and political classroom is not closely integrated with the large classroom of society， the characteristics of TCM culture are not highlighted， and the current situation of practice-based construction does not match the needs of talent cultivation. Based on systematic thinking， the construction of a collaborative education of TCM culture and red culture should start from the following four aspects： cultural integration-cultivating ideological and political education and ideological and political theory courses of TCM culture； medical and educational collaboration-leveraging the synergistic educational effect of clinical practice； practice reinforcement-integrating the small classroom of ideological and political education into the big classroom of society； and “double innovation” promotion-creating an educational environment for innovation and entrepreneurship of TCM.

OBJECTIVE To provide a reference for revising the safety content of traditional Chinese medicine（TCM） instructions. METHODS A systematic analysis was conducted on the relevant announcements on the revision of TCM instruction from 2013 to 2024， including the year of publication， drug name， drug formulation， announcement release time， and the average number of revisions made to three safety contents （contraindication， adverse drug reaction， and precaution）. According to the report data of national adverse drug reaction monitoring from 2013 to 2024， analyze the proportion of TCM in all adverse drug reactions， the composition ratio of adverse drug reaction of different dosage forms of drugs [TCM injection， oral TCM， other （topical） TCM]. RESULTS From 2013 to 2024， the National Medical Products Administration issued a total of 101 notices on the revision of TCM instruction， involving 241 types of TCM. Among them， there were 163 types of oral TCM， 25 types of TCM injection， and 53 types of other （topical） TCM. There were 3， 10 and 0 types of TCM injection， oral TCM， and other （topical） TCM with missing safety content， respectively. The main source of adverse drug reaction data for TCM injections was post- marketing monitoring data （accounting for 48.00%）； the main source of adverse drug reaction data for oral TCM was monitoring data （accounting for 71.17%）； 73.58% of other （topical） TCM did not mention the source of adverse drug reaction data. The report on national adverse drug reaction monitoring showed that the proportion of all adverse drug reactions of TCM had decreased from 17.3% in 2013 to 12.1% in 2024. Among them， the proportion of adverse drug reaction of TCM injection in the three dosage forms of TCM had decreased from 61.3% in 2015 to 24.6% in 2024， while the proportion of adverse drug reaction of oral TCM in the three dosage forms of TCM had increased from 34.7% in 2015 to 64.0% in 2024. CONCLUSIONS The risk management of TCM safety content has achieved results in China， but still faces three major challenges： strongdependence on passive monitoring， insufficient data traceability， and missing key content. It is urgent to improve safety content by dosage form， optimize data sources， and fully utilize real-world evidence to supplement safety content.

Objective To investigate the identification of octreotide(OCT)modified chitosan(CS)miR-155 molecular beacon nanoparticles(CS-miR-155-MB-OCT)and imaging of lung cancer cells for the early screening of lung cancer.Methods A nude mouse model of lung transplantation tumor was established by injecting A549 lung cancer cells into tail veins to establish lung xenograft models.Cre adenovirus was injected through nasal cavity,and mice were killed at 4,6,8 and 12 weeks after adenovirus injection to establish lung cancer models of atypical hyperplasia,adenoma,carcinoma in situ and adenocarcinoma of lung in LSL K-ras G12D transgenic mice at different pathological stages.Lung tissue samples were taken and observed by HE staining.Immunohistochemistry were used to detect the expression of somatostatin receptor 2(SSTR2).Real-time fluorescence quantitative PCR was used to detect miR-155 expression levels in lung xenograft models and transgenic mice at different stages of lung cancer.Then CS-miR-155-MB and CS-miR-155-MB-OCT were injected via tail vein in lung xenograft models.CS-miR-155-MB-OCT was injected via tail vein in transgenic mice models.The fluorescence signals of lung in nude mice and transgenic mice at different disease stages were imaged by living imaging system.Frozen slices of lung tissue were made.The source of fluorescence signal was detected by laser confocal scanning microscope(CLSM).Results HE staining showed that lung transplantation tumor models and lung cancer models of atypical hyperplasia,adenoma,carcinoma in situ and lung adenocarcinoma at different pathological stages were successfully constructed.Immunohistochemical analysis showed somatostatin receptor 2(SSTR2)was expressed in transplanted lung tumor and tissue at different pathological stages.In transgenic mouse models,the expression of miR-155 was gradually increased as the disease progressed(P＜0.05).In lung xenograft models,the fluorescence signals were significantly higher in the CS-miR-155-MB-OCT group than those of the CS-miR-155-MB group(P＜0.05).In transgenic mouse models,the fluorescence signals gradually increased with the gradual progression of lesions(P＜0.05).After re-imaging the lung tissue,it was found that the fluorescence signal came from lung,and CLSM showed that the fluorescence signal came from cancer cells and some normal alveolar epithelial cells.Conclusion CS-miR-155-MB-OCT can dynamically reflect the occurrence and development of lung cancer according to changes of different fluorescence intensity,thus providing a new technology for the early diagnosis of lung cancer.

Objective:To explore the correlation between grip strength promotion and improvement of body composition and metabolic disorders in health examination population of different genders.Methods:In this retrospective cohort study, clinical data of 600 people who received health examination and grip strength check-up two times or more in the Medical Examination Center of Peking University Third Hospital from January 2018 to November 2022 were selected. The general data, physical examination, biochemical parameters, body composition and grip strength results were collected. After the first physical examination, the grip strength test was conducted, appropriate resistance strength exercises were given based on individual evaluation results. A health lecture was held, and the information related to health exercise was pushed through WeChat official account every week. The grip strength test was completed at the same time at the second physical examination, and the difference between the two test results was calculated before and after the second physical examination. The generalized estimation equation was used to analyze the correlation between the improvement of grip strength and the improvement of body composition and metabolic disorders in different gender health-check population.Results:In man and women, the body mass index [(25.50±3.66) vs (25.33±3.74) kg/m 2, (22.41±3.55) vs (22.25±3.46) kg/m 2] and grip strength [(42.71±7.30) vs (41.77±7.36) kg, (25.28±5.30) vs (23.98±4.87) kg] at the second health check-up were all significantly higher than those at the first time, and the diastolic blood pressure [(72.79±10.30) vs (74.47±9.85) mmHg (1 mmHg=0.133 kPa), (66.93±8.90) vs (68.92±9.42) mmHg] and serum homocysteine [(17.96±14.09) vs (19.27±14.26) μmol/L, (9.47±3.91) vs (10.26±3.90) μmol/L] were all significantly lower than those at the first time (all P<0.05). Among man, the low-density lipoprotein cholesterol (LDL-C) at the second physical examination was significantly lower than that at the first time [(2.94±0.78) vs (3.00±0.69) mmol/L] (all P<0.05). Among women, the systolic blood pressure and uric acid at the second health check-up were both significantly lower than those at the first time [(109.34±12.85) vs (110.54±12.32) mmHg, (276.91±62.46) vs (287.16±68.78) μmol/L], and the waist-hip ratio was significant higher (85.8%±5.1% vs 85.4%±5.0%) (all P<0.05). In males, the decreased aspartate aminotransferase ( OR=0.932, 95% CI: 0.888-0.978) and the increased skeletal muscle index ( OR=75.370, 95% CI: 29.012-195.806) were both positively correlated with the elevation of grip strength (all P<0.05); and in females, the decreased homocysteine ( OR=0.876, 95% CI: 0.782-0.982) and glycosylated hemoglobin ( OR=0.423, 95% CI: 0.222-0.805) and increased skeletal muscle index ( OR=22.918, 95% CI: 11.114-47.256) were all positively correlated with the elevation of grip strength (all P<0.05). Conclusion:There is a positive correlation between the improvement of grip strength and the improvement trend of body composition and metabolic disorders in in health examination population of different genders.

Objective:To evaluate the value of CEA, CYFRA21-1 and CA125 tests in opportunistic screening of non-small cell lung cancer (NSCLC) based on meta-analysis.Methods:The original research literatures on the diagnostic value of CEA, CYFRA21-1 and CA125 in Chinese NSCLC patients were searched from databases of PubMed, Embase, The Cochrane Library, CNKI, VIP, Database and Wanfang database from establishment to June 2023. The literature screening, data extraction and quality evaluation were carried out independently by two researchers. The quality evaluation tool of diagnostic accuracy studies was used to evaluate the quality of the literature. A summary receiver operating characteristic (SROC) curve was used to assess the overall effectiveness of the tests. The outcome stability and publication bias were detected by using sensitivity analysis and Deeks′ test.Results:A total of 23 studies met the inclusion and exclusion criteria were included. The results of meta-analysis showed that the overall sensitivity of CEA, CYFRA21-1 and CA125 alone in the diagnosis of NSCLC was relatively low, it was 0.49(95% CI: 0.43-0.55), 0.56(95% CI: 0.49-0.63) and 0.41(95% CI: 0.33-0.49), respectively. The overall sensitivity of the combined detection of the three markers for the diagnosis of NSCLC increased to 0.83(95% CI: 0.69-0.91), but the overall specificity decreased to 0.76(95% CI: 0.69-0.83). Conclusions:The single detection of CEA, CYFRA21-1 and CA125 is not recommended for screening NSCLC in population receiving physical examination. Although the sensitivity of the combined detection of CEA, CYFRA21-1 and CA125 for screening NSCLC is improved, but the specificity is decreased, the misdiagnosis rate is increased, so the screening effect is limited.

Objective:To assess a value of dual energy index(DEI)and effective atomic number(Zeff)of dual-energy computed tomography(DECT)combined with slope of energy spectrum curve in identifying the component of urinary tract stones.Methods:The clinical and DECT imaging data of 111 patients with urinary tract stones who admitted to Nantong Haimen People's Hospital from October 2019 to October 2022 were selected,and the diameters of the urinary tract stones of all patients were<5 mm.The components of outside body stones of all patients were analyzed by infrared spectrum.The accuracy,sensitivity and specificity of the DEI,Zeff,slope of energy spectrum curve and the combination of the them were respectively calculated in identifying the components of urinary tract stones.Results:In 111 patients,the patients with calcium oxalate stones were 75(67.57%),and ones with hydroxyapatite were 15 cases(13.51%),and ones with uric acid stones were 21 cases(18.92%),and there were no other type of stone included cysteine.The differences of CT values(F=487.691,P<0.001),DEI values(F=395.553,P<0.001),Zeff values(F=818.689,P<0.001)and the slopes of energy spectrum curves(H=19.615,P<0.001)were statistically significant among the three types of stones.The overall accuracies of DEI,Zeff and slope of energy spectrum curve were 87.39%(97/111),84.68%%(94/111)and 81.98%(91/111)in identifying the components of urinary tract stone.The range of diagnostic accuracies of DEI,Zeff and the slope of energy spectrum curve was between 80%and 100%for calcium oxalate stones,hydroxyapatite and uric acid stones.The overall accuracy of DEI,Zeff combined with slope of energy spectrum curve was 94.59%(105/111)in identifying the components of urinary tract stones.The diagnostic accuracies of DEI,Zeff combined with slope of energy spectrum curve were respectively 94.59%,94.59 and 100%for calcium oxalate stones,hydroxyapatite and uric acid stones.Conclusion:Compared with the single indicator of DECT,the DEI and Zeff combined with the slope of the energy spectrum curve showed better diagnostic accuracy in identifying the components urinary track stones.

Methods: (i) Animal experiments. This study conducted experiments using specific pathogen-free (SPF) grade male C57BL/6J wild-type (WT) mice and APP/PS1 double transgenic mice. The animals were divided into three groups: WT group (WT mice, n = 5, receiving distilled water daily), APP/PS1 group (APP/PS1 double transgenic mice, n = 5, receiving distilled water daily), and BSTSD group [APP/PS1 double transgenic mice, n = 5, treated with BSTSD suspension at a dosage of 27 g/(kg·d) for 90 d]. Cognitive function was assessed using the Morris water maze (MWM). Post-experiment, hippocampal tissues were collected for analysis of pyramidal cell and synaptic morphology through hematoxylin-eosin (HE) staining and transmission electron microscopy (TEM). (ii) Cell experiments. The HT-22 cells were divided into control group (untreated), Aβ25-35 group (treated with 20 μmol/L Aβ25-35 for 24 h), icariin group (pre-treated with 20 μmol/L icariin for 60 min, followed by 20 μmol/L Aβ25-35 for an additional 24 h), and icariin + LY294002 group [treated with 20 μmol/L icariin and 20 μmol/L LY294002 (an inhibitor of the phosphoinostitide 3-kinases (PI3K) signaling pathway) for 60 min, then exposed to 20 μmol/L Aβ25-35 for 24 h], and cell viability was measured. Western blot was used to detect the expression levels of synapse-associated proteins [synaptophysin (SYP) and postsynaptic density-95 (PSD-95)] and PI3K signaling pathway associated proteins [phosphorylated (p)-PI3K/PI3K, p-protein kinase B (Akt)/Akt, and p-mechanistic target of rapamycin (mTOR)/mTOR]. Results: (i) Animal experiments. Compared with APP/PS1 group, BSTSD group showed that escape latency was significantly shortened (P < 0.01) and the frequency of crossing the original platform was significantly increased (P < 0.01). Morphological observation showed that pyramidal cells in the hippocampal CA1 region were arranged more regularly, nuclear staining was uniform, and vacuole-like changes were reduced after BSTSD treatment. TEM showed that the length of synaptic active zone in BSTSD treatment group was increased compared with APP/PS1 group (P < 0.01), and the width of synaptic gap was decreased (P < 0.01). (ii) Cell experiments. Icariin had no obvious toxicity to HT-22 cells when the concentration was not more than 20 μmol/L (P > 0.05), and alleviated the cell viability decline induced by Aβ25-35 (P < 0.01). Western blot results showed that compared with Aβ25-35 group, the ratios of p-PI3K/PI3K, p-Akt/Akt and p-mTOR/mTOR in icariin group were significantly increased (P < 0.01), while the protein expression levels of SYP and PSD-95 were increased (P < 0.01). These effects were blocked by LY294002 (P < 0.01). Conclusion BSTSD and icariin enhance cognitive function and synaptic integrity in AD models and provide potential therapeutic strategies through activation of the PI3K/Akt/mTOR pathway.
