ObjectiveTo explore the listed varieties and prescription characteristics of Chinese patent medicines for stroke in China， explore the medication rules of Chinese medicine for stroke， and provide guidance for further clinical research and development of Chinese patent medicines. MethodsExcel 2021 and the Ancient and Modern Medical Record Cloud Platform （V2.3.5） were used to systematically mine and analyze the varieties and prescriptions of Chinese patent medicines for stroke in China. ResultsA total of 244 Chinese patent medicines （two for different dosage forms of the same prescription）， 1 736 approval documents for Chinese patent medicines， 792 manufacturers， and 83 varieties of protected Chinese patent medicines were finally included in the database. The top three dosage forms were capsules （75）， pills （53）， and tablets （42）. There were 28 Chinese patent medicines for stroke in the National Essential Drug Catalogue （2018）， 129 in the National Essential Medical Insurance， Industrial Injury Insurance and Maternity Insurance Drug Catalogue （2023）， and 4 in the National Non-prescription Drug Catalogue. Among the 138 prescriptions screened out， Chinese patent medicines mainly treated stroke patients with the syndrome of Qi deficiency and blood stasis. The top three most frequent medicinal herbs were Chuanxiong Rhizoma （63）， Pheretima （47）， and Salviae Miltiorrhizae Radix et Rhizoma （47）. The medicinal herbs used were mainly warm， pungent， with the meridian tropism to the liver meridian. The correlation analysis showed that the herb pair with the highest support was Astragali Radix-Chuanxiong Rhizoma， and that with the highest confidence was Carthami Flos-Chuanxiong Rhizoma. Five herb combinations were identified based on the cluster analysis. ConclusionThe Chinese patent medicines for stroke mainly treat patients with the syndrome of Qi deficiency and blood stasis. The medicinal herbs used in the prescriptions mainly have the functions of activating blood and resolving stasis， extinguishing wind and stopping convulsions. Drug compatibility usually focuses on activating blood and resolving stasis， as well as expelling phlegm and opening orifices. This review of the varieties and prescription characteristics of Chinese patent medicines for stroke helps optimize clinical decision-making， guide drug research and development， promote medical research and scientific progress， and provide more effective support and guarantee for the treatment of stroke patients.

Objective To understand the respiratory protection competency of staff in hospitals.Methods Staff from six hospitals of different levels and characteristics in Beijing were selected,including doctors,nurses,medical technicians,and servicers,to conduct knowledge assessment on respiratory protection competency.According to exposure risks of respiratory infectious diseases,based on actual cases and daily work scenarios,content of respira-tory protection competency assessment was designed from three aspects:identification of respiratory infectious di-seases,transmission routes and corresponding protection requirements,as well as correct selection and use of masks.The assessment included 6,6,and 8 knowledge points respectively,with 20 knowledge points in total,all of which were choice questions.For multiple-choice questions,full marks,partial marks,and no mark were given respective-ly if all options were correct,partial options were correct and without incorrect options,and partial options were correct but with incorrect options.Difficulty and discrimination analyses on question of each knowledge point was conducted based on classical test theory.Results The respiratory protection competency knowledge assessment for 326 staff members at different risk levels in 6 hospitals showed that concerning the 20 knowledge points,more than 60％participants got full marks for 6 points,while the proportion of full marks for other questions was relatively low.Less than 10％participants got full marks for the following 5 knowledge points:types of airborne diseases,types of droplet-borne diseases,conventional measures for the prevention and control of healthcare-associated infec-tion with respiratory infectious diseases,indications for wearing respirators,and indications for wearing medical protective masks.Among the 20 knowledge questions,5,1,and 14 questions were relatively easy,medium,and difficult,respectively;6,1,4,and 9 questions were with discrimination levels of ≥0.4,0.30-0.39,0.20-0.29,and ≤0.19,respectively.Conclusion There is still much room for hospital staff to improve their respiratory protection competency,especially in the recognition of diseases with different transmission routes and the indications for wearing different types of masks.

Objective To explore the risk factors for the occurrence of adenomatous polyps in melanosis coli(MC),and to construct and validate a risk prediction model for the occurrence of adenomatous polyps in MC.Methods The clinical data of patients with melanosis coli who underwent colonoscopy in our hospital were retrospectively analyzed.The related risk factors,including gender,age,smoking history,drinking history,hypertension history,diabetes history,melanosis degree and so on,were collected.Establish a column chart model for predicting the risk of adenomatous polyps using R language,evaluate the model through C-index,calibration curve,and decision curve analysis(DCA),and validate the model internally using Bootstrap method.Results Gender,degree of melanosis,homocysteine,HbA1c,TSH,fecal occult blood,gallstones or polyps,HP infection were the independent influencing factors of adenomatous polyps in patients with melanosis of large intestine.The model had a good discrimination in predicting the risk of adenomatous polyps in patients with colorectal melanosis.Hosmer Lemeshow goodness of fit test showed that the P values of the training set and the validation set were 0.157 and 0.179,respectively(both＜0.05),indicating that the model fitted well.When the threshold probability of the training set and the validation level were both 0％to 100％,patients with melanosis of the colon may benefit from clinical intervention.Conclusion The risk model established by the above risk factors has good discrimination and good fit,which can provide reference for clinical decision-making.

3ʹ-Hydroxy-4ʹ-methoxy-2-hydroxy-5-bromochalcone (hereinafter referred to as C13) is a novel chalcone derivative obtained in the process of structural modification of DHMMF, the antitumor active compound of Resina Draconis, in our laboratory. In this study, we investigated the effects of C13 on the proliferation and apoptosis of human gastric cancer HGC-27 and AGS cells and its potential mechanism of action. Firstly, through methyl thiazolyl tetrazolium (MTT), colony formation assay, and 5-ethynyl-2'-deoxyuridine (EdU) staining, we found that C13 inhibited the proliferation ability of human gastric cancer HGC-27 and AGS cells. Using flow cytometry and Western blot, it was found that C13 induced apoptosis in human gastric cancer HGC-27 and AGS cells, and up-regulated the protein level of cleaved poly ADP-ribose polymerase (cleaved-PARP). The results of RNA sequencing analysis showed that the Erb-b2 receptor tyrosine kinase 4/phosphoinositide 3-kinases/AKT (ErbB4/PI3K/AKT) signaling pathway may be involved in anti-gastric cancer activity of C13. Finally, the results of immunoblotting assay showed that C13 treatment down-regulated the protein levels of ErbB4 and phospho-ErbB4, as well as down-regulated the phosphorylation levels of PI3K and AKT in human gastric cancer HGC-27 and AGS cells, which verified the results from RNA-seq analysis. In conclusion, C13 inhibited the proliferation and induced apoptosis of human gastric cancer cells, which may be related to the down-regulation of ErbB4/PI3K/AKT signaling pathway. This study may provide a candidate drug for the treatment of gastric cancer.

Objective To explore characteristics of clinical parameters and cytokines in patients with drug-induced liver injury(DILI)caused by different drugs and their correlation with clinical indicators. Method The study was conducted on patients who were up to Review of Uncertainties in Confidence Assessment for Medical Tests(RUCAM)scoring criteria and clinically diagnosed with DILI.Based on Chinese herbal medicine,cardiovascular drugs,non-steroidal anti-inflammatory drugs(NSAIDs),anti-infective drugs,and other drugs,patients were divided into five groups.Cytokines were measured by Luminex technology.Baseline characteristics of clinical biochemical indicators and cytokines in DILI patients and their correlation were analyzed. Results 73 patients were enrolled.Age among five groups was statistically different(P=0.032).Alanine aminotransferase(ALT)(P=0.033)and aspartate aminotransferase(AST)(P=0.007)in NSAIDs group were higher than those in chinese herbal medicine group.Interleukin-6(IL-6)and tumor necrosis factor alpha(TNF-α)in patients with Chinese herbal medicine(IL-6:P<0.001;TNF-α:P<0.001)and cardiovascular medicine(IL-6:P=0.020;TNF-α:P=0.001)were lower than those in NSAIDs group.There was a positive correlation between ALT(r=0.697,P=0.025),AST(r=0.721,P=0.019),and IL-6 in NSAIDs group. Conclusion Older age may be more prone to DILI.Patients with NSAIDs have more severe liver damage in early stages of DILI,TNF-α and IL-6 may partake the inflammatory process of DILI.

Objective·To analyze the expression of cancer-testis antigen(CTA)family member SPANXB(sperm protein associated with the nucleus on the X chromosome B)in liver cancer and its correlation with the prognosis of liver cancer patients,and to explore the impact of SPANXB on liver cancer cell proliferation and its potential mechanism.Methods·By using liver cancer sample data from the cancer genome atlas(TCGA)database,the expression of SPANXB in liver cancer tissue and its correlation with patient survival were analyzed.By constructing stable knockdown of SPANXB and stable overexpression of SPANXB in liver cancer cell lines,the effects of SPANXB on liver cancer cell proliferation were evaluated with live cell imaging experiments,EdU cell proliferation experiments and plate clone formation experiments.The regulatory pathways of SPANXB in liver cancer cell proliferation were explored through RNA-sequence(RNA-seq),and the effect of SPANXB on liver cancer cell cycle was validated through cell cycle experiments.Immunoprecipitation-mass spectrometry(IP-MS)was used to explore the proteins that interacted with SPANXB,and co-immunoprecipitation(Co-IP)was used to verify their interaction.Results·The expression of SPANXB mRNA in liver cancer tissues was higher than that in normal tissues(P=0.003),and was negatively correlated with the survival of liver cancer patients.Stable knockdown of SPANXB could reduce the proliferation and clone formation ability of liver cancer cells,while stable overexpression of SPANXB could promote these processes.The analysis results of RNA-seq showed that knockdown of SPANXB could lead to downregulation of DNA replication and G1/S cell cycle transition-related pathways.The results of cell cycle experiments showed that knockdown of SPANXB could result in changes in the liver cancer cell cycle.The results of IP-MS and Co-IP showed that SPAXNB interacted with cell cycle-related proteins such as mitotic arrest defect 2-like protein 1(MAD2L1)and WD repeat domain 5(WDR5).Conclusion·The high expression of SPANXB is negatively correlated with the prognosis of liver cancer.SPANXB may regulate the cell cycle and enhance the proliferation activity of liver cancer cells by interacting with MAD2L1 and WDR5.
