OBJECTIVE To explore the clinical risks and monitoring essentials associated with tonifying Chinese patent medicine. METHODS The varieties of tonifying Chinese patent medicines listed in the National Basic Drug List （2024 edition） were counted. Package inserts were collected using software such as “Dingxiangyuan” and then classified and organized according to criteria such as “drug name”“ingredients”“contraindications”“precautions”“drug interactions”. The names of traditional Chinese medicine （TCM） decoction pieces were standardized in accordance with the Chinese Pharmacopoeia （2020 edition） and other relevant standards； literature was reviewed to compile information on TCM decoction pieces that required caution/were contraindicated in special populations， as well as tonifying Chinese patent medicines and their related clinical applications. Then， a database for tonifying Chinese patent medicines was ultimately established by relying on the hospital’s internal information system， so as to conduct an in-depth exploration of the clinical usage risks and key monitoring points of tonifying Chinese patent medicines. RESULTS A total of 222 tonifying traditional Chinese medicines were evaluated. Contraindications or requirements for cautious use were identified in 91 （40.99%） for hepatic or renal impairment， 9 （4.05%） for hypertension， and 8 （3.60%） for pediatric patients， and 109 （49.10%） were designated as contraindicated or requiring caution for athletes. CONCLUSIONS Although tonifying Chinese patent medicines are indicated for deficiency patterns， their use is accompanied by measurable clinical risk， especially in individuals with hepatic or renal compromise who are prone to adverse reactions.

As research delves deeper into the mechanisms of tumor immune responses,studies reveal the importance of microbial com-munities within the tumor microenvironment in tumor progression and their interactions with the host immune system.Intratumoral micro-biota could influence the tumor microenvironment,thereby promoting or inhibiting tumor growth and development.Despite this import-ance,the specific role of intratumoral microbiota impacting cancer immunotherapeutic efficacy remains largely unexplored.A deeper under-standing of the characteristics and biological functions of tumor-specific microbiota heralds a potential revolutionary innovation in cancer treatment.In this review,we introduce the discovery and sources of intratumoral microbiota,also addressing its composition,and discuss tumor tissue characteristics.Moreover,we briefly review the history of cancer immunotherapy development with a particular focus on the research progress concerning the impact of intratumoral microbiota on cancer immunotherapy.Furthermore,we explore emerging strategies that combine targeting intratumoral microbiota with immunotherapy to enhance immune efficacy,inhibit tumor progression,and improve cure rates,anticipating that this approach could represent a new direction for enhancing treatment outcomes and prospects.

Objective:To screen the key exosomal long non-coding RNAs (lncRNAs) molecules that cause nasopharyngeal carcinoma cells to develop chemoradiotherapy resistance.Methods:In vitro, a model of concurrent chemoradiotherapy for human nasopharyngeal carcinoma cells was constructed, and the continuous shock method of high-dose concurrent chemoradiotherapy was used to induce the establishment of chemoradiotherapy-resistant nasopharyngeal carcinoma cell lines, and its resistance formation was verified. Exosomes produced by chemoradiotherapy-resistant cell lines and respective mother cell lines for nasopharyngeal carcinoma were extracted and identified. Finally, biochip technology was used to detect the differential expression levels of exosomal lncRNAs. Results:After 10 repeated treatments of concurrent chemoradiotherapy, CNE-1 CRR and CNE-2 CRR were successfully obtained. Compared with the mother cell lines, CNE-1 CRR and CNE-2 CRR had a tendency to transform from epithelial to interstitial morphology, and the number of cell clones was higher, and the values of average lethal dose (D 0), quasi-threshould dose (D q), survival fraction after 2 Gy irradiation (SF 2) and cell survival rate were higher. Nasopharyngeal carcinoma cells were detected by PCR chip of exosomal lncRNAs. Compared with their respective mother cell lines, 18 lncRNAs in CNE-1 CRR exosomes were significantly up-regulated and 31 lncRNAs were significantly down-regulated, and 15 lncRNAs were significantly up-regulated and 38 lncRNAs were significantly down-regulated in CNE-2 CRR exosomes. CNE-1 CRR also had similar expression profiles to CNE-2 CRR. Conclusion:There are significantly up-regulated and down-regulated lncRNAs in the exosomes of CNE-1 CRR and CNE-2 CRR.

Malaria is an ancient infectious disease that threatens millions of lives globally even today. The discovery of artemisinin, inspired by traditional Chinese medicine (TCM), has brought in a paradigm shift and been recognized as the "best hope for the treatment of malaria" by World Health Organization. With its high potency and low toxicity, the wide use of artemisinin effectively treats the otherwise drug-resistant parasites and helps many countries, including China, to eventually eradicate malaria. Here, we will first review the initial discovery of artemisinin, an extraordinary journey that was in stark contrast with many drugs in western medicine. We will then discuss how artemisinin and its derivatives could be repurposed to treat cancer, inflammation, immunoregulation-related diseases, and COVID-19. Finally, we will discuss the implications of the "artemisinin story" and how that can better guide the development of TCM today. We believe that artemisinin is just a starting point and TCM will play an even bigger role in healthcare in the 21st century.

Objective:To explore the brain electrical activity and its correlation with polysomnography monitoring parameters in children with obstructive sleep apnea syndrome (OSAS) and primary snoring.Methods:It was a prospective observational study involving children aged 6-12 years who presented to the Sleep Center of Beijing Children′s Hospital, Capital Medical University for polysomnography monitoring due to snoring at sleep from July 1 to December 31, 2019.Clinical data, polysomnography monitoring and 6-min measurement of brain electrical activity were collected from all the subjects.According to the results of polysomnography monitoring, the subjects were divided into the primary snoring group and the OSAS group at varying degrees.Based on the electroencephalogram (EEG) wavelet analysis, the brain injury index obtained by EEG synchronization and complexity analysis was used to reflect the changes of brain electrical activity in children in the resting state.Rank sum test was used to test the differences in brain injury index and the percentage of each frequency band of brainwave.Multivariate linear regression method was used to analyze risk factors for EEG activity.Results:A total of 149 children were recruited, including 110 males and 39 females.There was no significant difference in the proportions of α, θ, β and δ waves among OSAS children at varying degrees(all P>0.05). The brain injury index of the primary snoring group, mild OSAS group, moderate OSAS group and severe OSAS group was 0 (0, 3), 14 (9, 16), 26 (24, 28), and 34(30, 44), respectively.There were statistically significant differences in the brain injury index among groups ( H=129.70, P<0.01). The brain injury index gradually increased from the primary snoring group to the severe OSAS group.Multivariate linear regression analysis showed that the obstructive apnea hypopnea index (OAHI), mean oxygen saturation and minimum oxygen saturation were independently correlated with the brain injury index (all P<0.05). Conclusions:There were no significant differences in the ratios of α, θ, β and δ waves among OSAS children at varying degrees, while the EEG complexity and synchronicity varied a lot.With the increase of OAHI, the brain injury index gradually increased.The brain injury index was independently correlated with OAHI, mean oxygen saturation and minimum oxygen saturation.

The composition of serum is extremely complex,which complicates the discovery of new pharmaco-dynamic biomarkers via serum proteome for disease prediction and diagnosis.Recently,nanoparticles have been reported to efficiently reduce the proportion of high-abundance proteins and enrich low-abundance proteins in serum.Here,we synthesized a silica-coated iron oxide nanoparticle and devel-oped a highly efficient and reproducible protein corona(PC)-based proteomic analysis strategy to improve the range of serum proteomic analysis.We identified 1,070 proteins with a median coefficient of variation of 12.56％using PC-based proteomic analysis,which was twice the number of proteins iden-tified by direct digestion.There were also more biological processes enriched with these proteins.We applied this strategy to identify more pharmacodynamic biomarkers on collagen-induced arthritis(CIA)rat model treated with methotrexate(MTX).The bioinformatic results indicated that 485 differentially expressed proteins(DEPs)were found in CIA rats,of which 323 DEPs recovered to near normal levels after treatment with MTX.This strategy can not only help enhance our understanding of the mechanisms of disease and drug action through serum proteomics studies,but also provide more pharmacodynamic biomarkers for disease prediction,diagnosis,and treatment.

BACKGROUND: The mortality of lung cancer ranks first among all malignant tumors, but there are few studies on the effect of different segmentectomy on lung function in patients with early lung adenocarcinoma. The purpose of this study was to evaluate the degree of lung function preservation and short-term results of preoperative planning combined with fluorescence thoracoscopic precision segmentectomy and traditional segmentectomy in patients with early lung adenocarcinoma. METHODS: From January 1, 2020 to October 31, 2020, 60 patients underwent thoracoscopic segmentectomy in the Department of Thoracic Surgery of the First Affiliated Hospital of University of Science and Technology of China: 30 patients in precision segmentectomy group and 30 patients in traditional segmentectomy group. The clinicopathological features, perioperative data and postoperative pulmonary function of the two groups were compared. RESULTS: The operation time of the precision group was shorter than that of the traditional group, and the difference was statistically significant (P<0.05). The preoperative pulmonary function accuracy group and the traditional group in forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and carbon monoxide diffusing capacity (DLCO) were (3.65±0.63) L vs (3.54±0.64) L, (2.72±0.50) L vs (2.54±0.48) L and (20.36±3.02) mL/mmHg/min vs (19.16±3.18) mL/mmHg/min, respectively. One month after operation, the FVC, FEV1 and DLCO of pulmonary function accuracy group and traditional group were (3.35±0.63) L vs (2.89±0.57) L, (2.39±0.54) L vs (2.09±0.48) L and (17.43±3.10) mL/mmHg/min vs (15.78±2.865) mL/mmHg/min, respectively. Three months after operation, the FVC and DLCO of pulmonary function accuracy group and traditional group were (3.47±0.63) L vs (3.20±0.56) L and (19.38±3.02) mL/mmHg/min vs (17.79±3.21) mL/mmHg/min, respectively. CONCLUSIONS Preoperative planning combined with fluorescence thoracoscopic precise segmentectomy provides advantages in intersegmental plane recognition, vascular anatomy and postoperative recovery, which significantly shortens the operation time and makes the treatment more accurate.

Objective:To summarize the clinical characteristics of patients with coronavirus disease 2019 (COVID-19) infected with Delta variant, so as to provide further references for clinical diagnosis and treatment.Methods:A real-world study was conducted to analyze the characteristics of 166 COVID-19 patients infected with Delta variant at Guangzhou Eighth People’s Hospital, Guangzhou Medical University.Results:The study enrolled 5 asymptomatic cases, 123 non-severe cases (mild and moderate type), and 38 severe cases (severe and critical type). Among these patients, 69 (41.6%) were male and 97 (58.4%) were female, with a mean age of 47.0±23.5 years. Thirty-nine cases (23.5%) had received 1 or 2 doses of inactivated vaccine. The incidence of severe COVID-19 cases was 7.7% in 2-doses vaccinated patients, which was lower than that of 11.5% in 1-dose and 26.8% in unvaccinated patients. The proportion of severe cases in 2 dose-vaccinated patients was 7.7%, which was lower than that of 11.5% in 1-dose vaccinated patients and 26.8% in unvaccinated patients, but the difference was not significant ( P>0.05). The most common clinical symptom was fever (134 cases, 83.2%), and 39.1% of cases presented with high-grade fever (≥39 °C); other symptoms were cough, sputum, fatigue, and xerostomia. The proportion of fever in severe cases was significantly higher than that of non-severe cases (97.4% vs. 76.4%, P<0.01). Similarly, the proportion of severe cases with high peak temperature (≥39 ℃) () was also higher than that of non-severe cases (65.8% vs. 30.9%, P<0.01). The median minimal Cycle threshold (Ct) values of viral nucleic acid N gene and ORFlab gene were 20.3 and 21.5, respectively, and the minimum Ct values were 11.9 and 13.5, respectively. Within 48 h of admission, 9.0% of cases presented with decreased white blood cell counts, and 52.4% with decreased lymphocyte counts. The proportions of increased C-reactive protein, serum amyloid A, interleukin 6, and interleukin 10 were 32.5%, 57.4%, 65.3%, and 35.7%, respectively. The proportions of elevated C-reactive protein, serum amyloid A and interleukin-6 in severe cases were significantly higher than those in non-severe cases ( P<0.01). Logistic regression analysis showed that older age and higher peak temperature were associated with a higher likelihood of severe cases ( OR>3, 95% CI: 2-7, P<0.01). In terms of treatment, traditional Chinese medicine (TCM) was used in 97.6% of non-severe cases and 100% in severe cases. Other treatments included respiratory and nutritional support, immunotherapy (such as neutralizing antibodies and plasma of recovered patients). The median times from admission to progression to severe cases, of fever clearance, and of nucleic acid conversion were 5 days, 6 days and 19 days, respectively. No deaths were reported within 28 days. Conclusions:The symptoms of Delta variant infection in Guangzhou are characterized by a high proportion of fever, high peak temperature, long duration of fever, high viral load, a long time to nucleic acid conversion, and a high incidence of severe cases. The severe cases exhibit a higher percentage of elderly patients, a longer duration of fever and have a higher fever rate and a higher hyperthermia rate than non-severe cases. Age and hyperthermia are independent risk factors for progression to severe disease. The combination of TCM and Western medicine can control the progression of the disease effectively.

Objective:To understand the employment psychology of college students in traditional Chinese medicine universities through analyzing relevant influencing factors, and to provide solutions to improve employment quality of the medical students.Methods:An online questionnaire survey on employment psychology and employment situation was conducted from August to September in 2017 among 384 students who had graduated from Longhua Hospital of Shanghai University of Traditional Chinese Medicine from 2013 to 2017. SPSS 19.0 was used for chi-square test and linear trend test on the survey results.Results:A total of 374 valid questionnaires were recovered, with the effective recovery rate of 97.4%. The results showed that the most important factors to be considered were professional counterparts (77.01%, 288 students), salary (75.67%, 283 students) and development prospect (69.52%, 260 students) and the most important psychological characteristics were hesitation and contradiction (50.8%, 190 students) and anxiety (25.13%, 94 students). The study found that employment psychology was related to students' family situation, category, temperament and performance during their education period.Conclusion:Students have different employment psychology, which can be improved by consummating career planning, broadening employment channels, combing employment policies, supplementing professional shortcomings, and improving comprehensive skills. Meanwhile, colleges and universities can expand their practice bases, provide employment counseling, and improve education resources, speed up the construction of the second classroom, pay attention to special groups to conduct employment guidance and improve the quality of employment.
