BACKGROUND: The STAR (Scientific, Transparent, and Applicable Rankings) working group conducts regular evaluations of Chinese guidelines and consensus statements. This study gathered insights from STAR working group members using qualitative interviews. METHODS: From March to August 2023, members of the STAR specialist committees were interviewed using semi-structured interview outline. The interviewees were selected through purpose-based sampling. Subject analysis was employed to summarize the findings. RESULTS: We conducted interviews with 37 members from 36 committees and summarized the contents into four main themes and 16 specific topics. The value of STAR in enhancing the development and selection of high-quality guidelines in China was commonly mentioned. Challenges identified included the lack of resources and suboptimal organizational structures, collaboration, and evaluation efficiency. Suggestions for the STAR tool included developing extensions for different guideline types, adjusting certain items, and better covering guideline applicability. The promotion of STAR and the consideration of an international committee for global outreach were also highlighted. CONCLUSION STAR has exerted a substantial influence on the evaluation of Chinese guidelines, and the insights gained from interviews offer valuable directions for its further enhancement.

Objective To predict the core targets and action pathways of Hedysari Radix based on UPLC-MS/MS and network pharmacology methods,and to verify the results of network pharmacology by molecular docking and molecular dynamics techniques.This article aims to investigate immune regulation mechanism of effective components absorbed into blood from Hedysari Radix.Methods Qualitative quantification of effective components absorbed into blood from Hedysari Radix were operated by using UPLC-MS/MS technique.The corresponding targets of effective components absorbed into blood from Hedysari Radix were screened by TCMSP and HERB databases.Targets of immune-related disease were obtained through DisGeNET,OMIM,TTD,and MalaCards databases.The network of"components absorbed into blood from Hedysari Radix-immune-related diseases"was then constructed.GO and KEGG enrichment analysis and mapped the PPI network were performed.Molecular docking and molecular dynamics techniques were applied for validation.Results A total of 8 prototype components absorbed into blood,synergistically acting on 101 targets,were identified by UPLC-MS/MS.They mediated 538 biological processes including immune response,positive regulation of gene expression,receptor binding,and cytokine activity.Meanuhile,116 signaling pathways,such as HIF-1,Toll-like receptor,JAK-STAT,T cell receptor,PI3K-Akt,and FoxO etc.were involved.The core targets were MAPK14,PTGS2,MMP9,PPARG,CCND1,etc..The results of molecular docking showed that formononetin and calycosin had strong docking binding activity with MAPK14.And molecular dynamics simulations further demonstrated that the binding between MAPK14 and formononetin or calycosin had good structural stability and binding affinity.Conclusion The results of serum pharmacochemistry,network pharmacology and molecular dynamics were verified to reveal the material basis and mechanism of Hedysari Radix in regulating immunity.The aim of this study is to provide scientific basis for its immunomodulatory mechanism.

Objective:To evaluate the safety and clinical efficacy of transcatheter arterial chemoembolization (TACE) combined with portal vein embolization (PVE) and percutaneous microwave ablation liver partition with PVE for planned hepatectomy in patients with hepatocellular carcinoma (HCC) with insu-fficient remnant liver volume.Methods:The clinical data of 51 patients with initially unresectable HCC due to insufficient remnant liver volume admitted to Zhejiang Provincial Tongde Hospital and Zhejiang Provincial People’s Hospital from January 2014 to December 2021 were retrospectively analyzed, including 37 males and 14 females, aged (56.7±11.2) years old. Patients were divided into two groups according to the treatment prior to hepatectomy: percutaneous microwave ablation liver partition combined with PVE (AP group, n=12) and TACE with PVE (TP group, n=39). Patients who successfully underwent planned hepatectomy in the above two groups were marked as resectable AP group ( n=10) and the resectable TP group ( n=29), respectively. Clinical data including the waiting time for surgery and the incidence of complications were analyzed. Patients were followed up by telephone or outpatient review. Kaplan-Meier and log-rank analysis were used for survival comparison. Results:The FLR growth rate was higher in AP group [76.5% (65.3%, 81.6%)] than that in TP group [31.4% (28.2%, 41.9%), P<0.01]. The waiting time for planned hepatectomy in the resectable AP group was 12.0 (11.3, 14.5) d, shorter than that in the resec-table TP group [21.0 (15.0, 29.0) d, P<0.05]. The incidence of postoperative complications was higher in the resectable AP group than that in the resectable TP group [80.0% (8/10) vs. 27.6% (8/29), P<0.05]. There was one perioperative death in the resectable AP group. The survival rate after PVE was lower in AP group than that in TP group, and the survival rate after hepatectomy was also lower in the resectable AP group than that in the resectable TP group (all P<0.05). Conclusion:For HCC patients with insufficient FLR, TACE combined with PVE is a safe and effective method for enlargement of liver remnant, whereas percutaneous microwave ablation liver partition with PVE showed a poor prognosis, despite the higher rate of FLR enlargement and shortened the waiting time for planned hepatectomy.

OBJECTIVE To analyze the current situation of pediatric drug use under centralized drug procurement， and to provide reference for the subsequent design of pediatric drug centralized procurement rules. METHODS The comparative analysis method was used to analyze the problems in the centralized procurement， clinical use and supply of pediatric drugs from the aspects of centralized procurement selection results and actual use of pediatric drugs， price difference and online prices of pediatric drugs. The solutions were put forward to optimize the centralized procurement and pricing rules of pediatric drugs. RESULTS & CONCLUSIONS The demands for pediatric drugs in China were increasing， but the supply of marketed pediatric drugs was insufficient （including insufficient coverage of disease fields， insufficient varieties， insufficient suitable dosage forms for children， insufficient specifications for children， etc.）， and the development of pediatric drugs was relatively difficult. After merging the dosage forms of centralized procurement according to the medical insurance list， some suitable dosage forms and specifications for children couldn’t be selected， resulting in a shortage of clinical pediatric medication. Relevant enterprises’ enthusiasm for developing and producing pediatric drugs and participating in online competitions had decreased. There was also the problem of underpricing of pediatric drugs under the drug price difference ratio rule. It is recommended that when conducting centralized drug procurement， special drugs for children should be grouped separately for centralized procurement based on attributes and the population covered by the indications. The specifications of suitable pediatric drugs that were not selected are converted into the agreed purchase quantity of medical institutions in a certain proportion. It is necessary to further optimize the pricing rules for pediatric specialized drugs， ensure a certain profit margin for such drugs， increase the willingness of production enterprises to research， develop and supply drugs， and thus ensure the use and supply of pediatric drugs.

Objective:To design a modified S1PR3 specific agonist, GPS-725.017, and investigate its protective effect on acute lung injury by promoting macrophage clearance of bacteria.Methods:A short peptide derived from the intracellular region of S1PR3 receptor was named GPS725.017, which was modified with norleucine (Nle) and myristicacid (myr) at its N terminus. Mice were divided into the sham operation group, solvent group and GPS-725.017 treatment group. The acute lung injury model was induced by endotracheal injection of E. coli (5×10 6 CFU), and the experimental group was treated with GPS-725.017 (10 mg/kg). The 48-h survival rate of mice was recorded. After 5 h of modeling, the bacterial load and inflammatory cytokines in peripheral blood and lung were detected, and Vps34 protein content in alveolar macrophages was determined by Western blot. After 12-h of modeling, lung tissues were collected for H&E staining and pathological scores. Results:Compared with the solvent group, the survival rate of mice in the GPS-725.017 treatment group was significantly improved ( P<0.01), the bacterial CFU in blood and alveolar lavage fluid was significantly lower than that in the solvent group ( P<0.001), and the levels of TNF-α and IL-1β in blood and alveolar lavage fluid were significantly lower than those in the solvent group ( P<0.001). Western blot showed that the expression level of Vps34 protein in alveolar macrophages was significantly higher than that in the solvent group ( P<0.01). Histopathology result showed that the pathological damage of lung in the treatment group was significantly less than that in the solvent group ( P<0.001). Conclusions:The modified synthetic S1PR3 specific agonist GPS-725.017 could specifically activate the S1PR3 receptor on the membrane of alveolar macrophages and up-regulate the expression level of intracellular Vps34 protein, which can promote the removal of bacteria in alveolar macrophages, significantly reduce the degree of lung injury and improve the survival rate in ALI mice.

Objective: To analyze the alterations and clinical significance of serum calcium binding protein S100A8/A9 and soluble receptor for advanced glycation end products (sRAGE) levels in patients with chronic obstructive pulmonary disease(COPD). Methods: Enzyme-linked immonosorbent assay was established to detect serum levels of S100A8/A9 and sRAGE in 203 patients with COPD[male166, female 37, aged 52-92 years, average years(69.72±9.079)] and in 41 smoking elderly non-COPD patients[male 35,female 6, aged 55-89 years, average years(68.66±8.74)], and 167 non-smoking healthy subjects as the control group[male 132, female 35, aged 57-92 years, average years(69.13±7.21)] from April 2018 to January 2019. The relationship between the S100A8/A9, sRAGE and clinical biomarkers [the percentage of fored expiratory volume in one second(FEV₁) in the predicted value, FEV₁/fored vital capacity(FVC), neutrophile granulocyte(NEU)%, pack-year] were investigated. The diagnostic value of S100A8/A9, sRAGE and their combined detection for COPD was analyzed using the subject operating characteristic curve. Results: The serum S100A8/A9 level [(2.70±1.11)μg/ml] in COPD patients was significantly higher than that in the smoking control group [(1.65±0.63) μg/ml] and the non-smoking control group[(0.99±0.48)μg/ml], t=5.807, P<0.000 1; t=18.45, P<0.000 1. The serum S100A8/A9 levels in patients with COPD[GOLD Ⅰ(2.08±1.08) μg/ml, GOLDⅡ (2.58±1.06) μg/ml, GOLD Ⅲ (2.69±1.12) μg/ml, GOLDⅣ (2.95±1.10)μg/ml] were significantly higher than the non-smoking control group(0.99±0.48)μg/ml, t=6.616, P<0.000 1; t=14.56, P<0.000 1; t=17.10, P<0.000 1; t=18.09, P<0.000 1.The serum sRAGE level [(0.29±0.25)ng/ml] in COPD patients was significantly higher than that in the smoking control group[(0.60±0.24)ng/ml] and the non-smoking control group[(0.85±0.35)ng/ml], t=7.367, P<0.000 1; t=18.14, P<0.000 1. The serum sRAGE levels in patients with COPD[GOLD Ⅰ(0.46±0.40),GOLDⅡ (0.28±0.25),GOLD Ⅲ (0.29±0.25),GOLD Ⅳ (0.25±0.19)ng/ml] were significantly lower compared with non-smoking control group[(0.85±0.35)ng/ml], t=3.459, P=0.000 5; t=10.23, P<0.000 1; t=13.95, P<0.000 1; t=11.70, P<0.000 1. Serum S100A8/A9 levels were positively correlated with smoking amount and NEU% (r=0.458 5, P<0.000 1; r=0.228 3, P=0.001 1), negatively correlated with FEV₁/FVC, the percentage of FEV₁ in the predicted value, and sRAGE(r=-0.190 6, P=0.006 4; r=-0.186 3, P=0.007 8; r=-0.201 7, P=0.003 9). sRAGE levels were negatively correlated with NEU% (r=-0.155 9, P=0.026 4). In the ROC curve, the area under the curve of S100A8/A9, sRAGE and combined detection were 0.922[95%CI(0.897-0.947)], 0.926[95%CI(0.899-0.952)]and 0.966 [95%CI(0.950-0.983)], respectively. Conclusion S100A8/A9 and sRAGE are closely correlated with the degree of airflow constrains and the levels of serum inflammatory mediators, which are expected to be as potential biomarkers of COPD.

Objective To accurately judge the tumor-feeding artery is the most important basis for a successful treatment of hepatocellular carcinoma (HCC) with super-selective hepatic arterial chemoembo lization therapy. This study aims to assess the clinical value of cone-beam CT hepatic arteriography (CBCT-HA) in detecting tumor-feeding arteries during the performance of conventional transarterial chemoembo lization (TACE), and to compare the diagnostic effects between CBCT-HA and non-selective hepatic DSA. Methods Twenty-three consecutive patients with inoperable HCC were enrolled in this study. TACE was carried out in all patients. During the performance of TACE, the DSA-HA, CBCT-HA, Lipiodol-TACE and Lipiodol-CBCT were performed separately. The imaging materials, including DSA-HA and CBCT-HA, were analyzed by two experienced interventional physicians together to judge the tumor-feeding arteries. Statistic analysis was conducted by using chi square test. Results Tumor stain and lipiodol accumulation were regarded as the “gold standard” of the presence of tumor-feeding artery, based on which the tumor-feeding artery was confirmed in 75 lesions. DSA-HA demonstrated positive tumor-feeding artery in 40 lesions, among which true-positive tumor-feeding artery was seen in 32 and false-positive one in 8. CBCT-HA showed positive tumor-feeding artery in 72 lesions, which included true-positive tumor-feeding artery in 68 and false-positive one in 4. The sensitivity of CBCT-HA in judging tumor-feeding artery was 90.7% (68/75), which was much higher than that of DSA-HA (42.6%, 32/75), the difference was statistically significant(P<0.001). The positive predictive value of CBCT-HA in detecting tumor-feeding artery was also higher than that of DSA-HA (94.4% vs. 80.0%; P=0.040). Conclusion Cone-beam CT hepatic arteriography is obviously superior to DSA hepatic arteriography in identifying tumor-feeding arteries, which is very helpful in guiding super-selective TACE for HCC.
