The clinical practice guidelines for Chinese patent medicines （CPM） provide reference for the selection of national drug catalogs， the formulation of prescription collections in medical institutions， and the clinical use of CPM， constituting an important part of traditional Chinese medicine （TCM） guidelines. As a crucial part of Chinese drug supply guarantee system， CPM plays an important role in the treatment， prevention， and healthcare of many disease categories， whereas the application of CPM has problems of misuse and even abuse. To standardize the application of CPM， a research team at Zhejiang Chinese Medical University developed the Reporting Items for Practice Guidelines in Healthcare for Chinese Patent Medicines （RIGHT for CPM） based on the RIGHT checklist framework. The RIGHT for CPM checklist gathers key information from published CPM guidelines， existing TCM reporting checklists， and the RIGHT checklist and its extensions to form an initial pool of reporting items. Seventeen experts from different disciplines were invited to conduct two rounds of Delphi surveys， and the final checklist was reviewed and approved for publication by 18 leading experts in TCM research and guideline reporting from China and abroad. The RIGHT for CPM checklist adds 16 sub-items and revises 2 sub-items on the basis of the RIGHT checklist， highlighting the characteristics of CPM guideline reporting. It considers CPM selection and inclusion criteria， policy access， indications and symptoms， drug combination instructions， drug use in special populations， precautions， and recommendations of Western medical physicians， among others. This can further improve the quality and transparency of CPM guideline reporting， promote standardized reporting of CPM guidelines， and facilitate the rational clinical use of CPM. This article interprets the development process of the RIGHT for CPM checklist and the items that highlight the characteristics of CPM guidelines， with a view to promoting the application of the RIGHT for CPM checklist.

Objective To investigate the expression and clinical significance of multiple endocrine neoplasia type 1(MEN1)gene in breast cancer.Methods The Cancer Genome Atlas(TCGA)database was used to analyze the relationship between MEN1 gene and clinicopathological characteristics of breast cancer.Kaplan-Meier method was used to observe the effect of MEN1 on survival of breast cancer patients.Gene Ontology(GO),Kyoto Encyclopedia of Genes and Genomes(KEGG),and gene set enrichment analysis(GSEA)were used to predict the function and signaling pathways of MEN1 related and interacting genes.Tumor Immune Estimation Resource(TIMER)and single sample gene set enrichment analysis(ssGSEA)were used to investigate the correlation between the level of immune infiltration and MEN1 expression in breast cancer.Results MEN1 was highly expressed in breast cancer patients,and its expression level was related to PAM50 subtype and menopause status(both P＜0.05).Kaplan-Meier survival analysis showed that high MEN1 expression was associated with poor clinical outcome(P=0.019).GO and KEGG enrichment analysis showed that MEN1 related and interacting genes were involved in biological processes(histone modification,histone-lysine methylation),cell components(methyltransferase complex and histone methyltransferase complex),molecular functions(histone-methyltransferase activity),and functional pathways(transcriptional disorders in tumors).GSEA identified that the highly expressed MEN1 phenotype was involved in vesicle-mediated transport,complement cascade,B-cell receptor signaling,lymphocyte-non-lymphocyte interaction,interleukin signaling,and cytokine signaling pathways in the immune system.CancerSEA single cell sequencing results indicated that the expression of MEN1 was positively correlated with angiogenesis in MDA-MB-231 cells(P＜0.05).TIMER analysis found that MEN1 in breast cancer was negatively correlated with the infiltration levels of macrophages and CD8+T cells,and positively correlated with the infiltration level of CD4+T cells(all P＜0.05).ssGSEA showed that the infiltration levels of 18 types of immune cells were negatively correlated with MEN1 expression(all P＜0.05).Conclusion High MEN1 level is associated with poor survival and immune infiltration in breast cancer patients.

Objective To investigate the types of diseases examined by ultrasonography in a certain island clinic,and to summarize the experience of ultrasound medical support in island area.Methods The ultrasound examination results of patients who were admitted to a certain island clinic from January 2017 to August 2022 were reviewed,and the types and characteristics of diseases examined by ultrasound were analyzed.Results A total of 2 043 patients underwent ultrasound examination.There were 76 disease categories and 1 579 diseases.The top five diseases were fatty liver(13.24%),kidney crystals(12.10%),kidney stones(10.70%),gallbladder polyps(6.33%)and ureteral stones with hydronephrosis(6.02%).Ultrasound could predict the pathological types of appendicitis and guide the clinical decision by observing the width of the appendiceal lumen and the layers of the appendiceal wall.Doppler-assessed ureteric jet could be used to determine the renal function of the affected side of ureteral calculi.Conclusion There are wide and varied disease categories in islands.Sonographers should have comprehensive abilities and qualities.This study can provide reference for the follow-up medical support on island area.

Objective To explore whether Yes-associated protein(YAP)affects occurrence and progression of liver fibrosis by regulating epithelial-mesenchymal transition(EMT).Methods In a 8-week-old C57BL/6 mouse model of CCl4-induced liver fibrosis,the effect of verteporfin(a YAP inhibitor)intervention was assessed with HE staining and by detecting liver biochemistry and expressions of YAP and EMT-related genes using immunohistochemistry and Western blotting.Transcriptome and proteomic sequencing and informatics analysis were used to investigate the main downstream pathways of YAP in liver fibrosis.Serum levels of YAP,N-cadherin,vimentin and Twist were examined in 60 healthy individuals,60 patients with chronic hepatitis B(CHB),and 60 patients with HBV-related liver cirrhosis.In another 24 C57BL/6 mice,the effects of Twist inhibitor alone or in combination with harmine(a YAP activator)on CCl4-induced liver fibrosis were evaluated by histopathological examination and Western blotting.Results The mouse models of liver fibrosis showed obvious structural damages of the liver lobes with formation of pseudolobules,and verteporfin treatment significantly improved these pathologies and lowered plasma ALT and AST levels of the mice.Transcriptome and proteomic sequencing and informatics analysis suggested that N-cadherin and Twist were differentially expressed in liver fibrosis in close correlation with YAP.Inhibition of YAP obviously downregulated hepatic N-cadherin and Twist protein expressions in the mice with liver fibrosis.In patients with CHB and liver cirrhosis,serum levels of YAP elevated obviously with the severity of liver fibrosis and were significantly correlated with N-cadherin,vimentin and Twist levels.In mice with liver fibrosis,inhibiting Twist effectively improved liver inflammation and fibrosis,while the combined treatment with YAP activator worsened hepatic collagen fiber deposition and increased hepatic YAP and α-SMA expressions.Conclusion EMT is an important pathogenic mechanism of liver fibrosis,and inhibiting YAP can alleviate liver fibrosis by reducing EMT.

Based on the resutls of literature review and interviews of experts, two rounds of Delphi surveys were conducted. The mean, importance ratio, coefficient of variation and coordination coefficient were used for assessment of survey from multiple perspectives, and finally form a framework model of factors affecting the efficacy of Tuina therapy. A total of 37 experts were selected for questionnaire surveys, the positive coefficients of experts' participatation in the first round and second round were 92.5% and 80.0%, respectively. The overall coordination coefficient in the second round is 0.68. The items were included into the consensus meeting if the importance ratio of items were equal to and more than 80%. After the expert consensus meeting, 22 items were included to form a framework model of factors affecting the efficacy of Tuina therapy, and summarized as 5 major influencing factors, including diagnostic factors, treatment factors, prognostic factors, patient factors, and doctor-patient communication. This framework can guide and help young Tuina practitioners to improve clinical efficacy. It is also clearly pointed out that the effect of Tuina for pain is not only related to disease diagnosis or manipulation, but also related to home exercise, health care, and doctor-patient communication.

OBJECTIVE:To study the effects of calcium ion(Ca2+)on the stability of total parenteral nutrition(TPN),and to provide reference for clinical use. METHODS:4 kinds of TPN containing different contents of Ca2+were prepared according to ster-ile operation procedure,and at room temperature,their microbial limit,appearance,pH value,osmotic pressure molar concentra-tion,the number of insoluble particle and emulsion particle size were investigated at 0,2,4,6,8 and 24 h. RESULTS:Within 24 h,no bacterial colony was found in TPN,and its appearance had no obvious change;pH value of TPN were all higher than 5 at different time points,without statistical significance(P>0.05);osmotic pressure molar concentration of TPN were all within the range of normal human blood(280-310 mOsmol/kg),without statistical significance(P>0.05). As the increase of Ca2+,the num-ber of insoluble particle ≥10 μm in TPN showed increasing tendency,with statistical significance (P<0.05);that ≥25 μm had no significant change,without statistical significance (P>0.05). There was statistical significance in emulsion partial size of TPN at different time points(P<0.05). CONCLUSIONS:Ca2+ can influence the stability of TPN,manifesting as the number of insolu-ble particle ≥10 μm and emulsion partial size increase. To garantee the safety of TPN use in the clinic,the concentration of biva-lent cation in TPN prescrption should be kept in reasonable range,and TPN should be used as soon as possible after preparation.
