On the premise of respecting the objective law of the occurrence and development of traditional Chinese medicine（TCM） dispensing granules， relevant national departments have gradually formed the research and formulation ideas of national drug standards for dispensing granules based on the experiences and lessons learned in the development process of quality standards， as well as the formation mechanism of national standards for dispensing granules. This has certain reference significance for the formulation path of TCM quality standards. Combined with the general situation of the published standards and specific cases， the research concepts of the national standards for dispensing granules were analyzed and summarized in this paper， and the analysis of the technical characteristics of the issued national standards was focused， including the introduction of standard decoction， the overall quality control of TCM， the whole process quality control and other research ideas. At the same time， it summarized the industry common problems in the research and development process of national standards for dispensing granules， such as the source and process control of medicinal materials， and strived to solve them together， encouraging the demonstration and application of new technological means in the field of TCM dispensing granules. Finally， based on the literature analysis， the shortcomings of the current national standards were discussed， and relevant suggestions were put forward to further improve the national standards for dispensing granules. Through the overall analysis， it is helpful to comprehensively understand the technical characteristics of the national standards for TCM dispensing granules， and provide reference for the scientific exploration and practice of quality control methods for TCM.

Objective To develop and validate a safety assessment scale for early mobilization in lung transplant patients after surgery.Methods From September 2022 to April 2023,a preliminary scale was constructed using literature analysis,expert meetings,and the Delphi method.From June 2023 to May 2024,a convenience sampling was used to select 135 patients admitted to the lung transplant center of a tertiary general hospital in Jiangsu Province.Item analysis,reliability analysis,and validity analysis were applied to adjust the items,forming the final scale.Results The post-operative early mobilization safety assessment scale for lung transplant patients includes 5 dimensions(consciousness level,vital signs,disease-related factors,mobility,and nutritional status)and 18 items.The inter-rater reliability of the scale is 0.985;the overall content validity index is 0.853;the split-half reliability is 0.716.The area under the receiver operating characteristic curve for predicting adverse events within 72 hours of mobilization is 0.845,with a 95％confidence interval of 0.767 to 0.917(P＜0.001).The optimal cutoff value is 18.5,with a sensitivity of 0.735 and a specificity of 0.782.Conclusion The developed safety assessment scale for early mobilization in lung transplant patients after surgery demonstrates good reliability and validity,and it can serve as a clinical tool to assess the safety of early mobilization activities in these patients.

Objective To analyze ethnic differences in mutations of the PIK3CA and TP53 genes among breast cancer patients from the Han, Tibetan, and Hui ethnic groups in Qinghai, China, and their associations with clinicopathological characteristics. Methods A total of 382 breast cancer tissue samples were retrospectively collected from surgical patients (Jan 2020−Dec 2022), comprising 200 Han, 93 Tibetan, and 89 Hui ethnicity. Mutations in PIK3CA (E542K, H1047R, and E545K) and TP53 (R273H and R175H) were detected by using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Correlations between mutations and clinicopathological parameters were analyzed. Results Significant differences were observed in pTNM stage, lymph node metastasis, molecular subtypes, and PR status among the three ethnic groups. The overall mutation rate of PIK3CA and TP53 was 48.95%. The PIK3CA-p.E542K mutation rate in Tibetan cohort was significantly higher than those in Han and Hui cohort, whereas the detection rate of the PIK3CA-p.E545K mutation was lower in Tibetan cohort than that in Han cohort. The PIK3CA-p.E542K mutation was associated with an increased risk of lymph node metastasis. The TP53-p.R175H mutation was significantly correlated with advanced pTNM stage, vascular invasion, and triple-negative breast cancer. The PIK3CA-H1047R and E545K mutations were enriched in the luminal A subtype of breast cancer. Conclusion Considerable ethnic disparities exist in breast cancer mutation profiles in Qinghai, with the high-frequency PIK3CA-p.E542K mutation in Tibetan population potentially serving as a region-specific therapeutic target. Mutations are closely linked to tumor aggressiveness and molecular subtypes, highlighting the value of PIK3CA/TP53 mutation detection for early risk stratification and personalized treatment of breast cancer in high-altitude populations.

Objective:To observe the changes of small airway parameters in patients with coal workers' pneumoconiosis in different disease stages by high resolution computed tomography (HRCT) , and analyze the correlation between them and the severity of the disease.Methods:From June 2016 to June 2023, 25 healthy volunteers and 71 untreated patients with coal worker's pneumoconiosis in the Fifth People's Hospital of Ningxia were selected as the research objects. The clinical and imaging data of the patients were collected, and the disease stages were performed according to the dust exposure history and high-kilovolt chest X-ray. The patients were divided into 4 groups: control group (25 cases) , coal workers' pneumoconiosis stage Ⅰ group (17 cases) , coal workers' pneumoconiosis stage Ⅱ group (32 cases) and coal workers' pneumoconiosis stage Ⅲ group (22 cases) . Quantitative chest HRCT parameters of each group were collected, including the square root of wall area at 10 mm inner perimeter (AWT-Pi10, Pi10) , airway wall thickness, airway wall volume, airway wall area percentage of the whole lung and the 5th, 6th, 7th and 8th level airways, and low attenuation area percentage (LAA%) of the whole lung. Pulmonary function indicators were collected, including forced expiratory volume in 1 second (FEV 1) and the percentage of its projected value [FEV 1 (%pred) ], the ratio of FEV 1 to forced vital capacity (FEV 1/FVC) and the percentage of its projected value[FEV 1/FVC (%pred) ]. One-way ANOVA or Kruskal-Wallis H test and Spearman rank correlation were used to analyze the difference and correlation. Results:Compared with control group, FEV 1, FEV 1 (%pred) , FEV 1/FVC and FEV 1/FVC (%pred) in stage Ⅱ and Ⅲ coal workers' pneumoconiosis groups were lower ( P<0.05) . In addition, the FEV 1 and FEV 1 (%pred) of the stage Ⅲgroup were lower than those of the stageⅡ group ( P<0.05) , and the FEV 1/FVC and FEV 1/FVC (%pred) of the stage Ⅲgroup were lower than those of the stage Ⅰgroup ( P<0.05) . Compared with stage Ⅰ group, Pi10 in stage Ⅲ group were increased ( P < 0.05) at the 6th and 8th level airways, and airway wall thickness and airway wall volume in the 6th, 7th and 8th level airways of stage Ⅲgroup increased ( P<0.05) . Correlation analysis showed that all pulmonary function indexes were negatively correlated with Pi10 of whole lung and the 6th, 7th and 8th level airways ( P<0.05) , all pulmonary function indexes were negatively correlated with airway wall thickness of the 7th and 8th level airways ( P<0.05) , and FEV 1/FVC (%pred) was negatively correlated with airway wall volume of the 7th and 8th level airways ( P<0.05) . FEV 1, FEV 1 (%pred) , FEV 1/FVC (%pred) were negatively correlated with percentage of airway wall area of whole lung and the 6th, 7th and 8th level airways ( P<0.05) . Conclusion:The quantitative airway parameters of coal workers' pneumoconiosis based on HRCT are correlated with pulmonary function indexes, which can reflect the severity of coal workers' pneumoconiosis.
