OBJECTIVE To sort out the evaluation mechanism and methodology of published cases of comprehensive clinical evaluation of drugs in China, and provide a reference for promoting standardized comprehensive clinical evaluation of drugs and strengthening policy transformation in China. METHODS Clinical comprehensive evaluation cases of drugs published in China from CNKI, Wanfang Data, PubMed and Web of Science were systematically searched, and the retrieval time was from the inception to December 31st, 2023. The summary and analysis were performed from the aspects of theme selection, indicator system construction, evaluation methods, comprehensive decision-making, quality control, etc. RESULTS A total of 143 pieces of literature were ultimately included from 2014 to 2023. The number of publications has shown a rapid upward trend since 2019. The subjects of the evaluation cases were mainly pediatric drugs, Chinese patent medicines, cardiovascular drugs and anti-tumor drugs. The evaluation dimensions were between 3-8, all involving safety and effectiveness dimensions. Most cases adopted rapid evaluation methods based on literature review and expert interviews/questionnaire surveys with less emphasis on real-world research. Most cases did not involve comprehensive decision-making, quality control, or policy transformation. CONCLUSIONS The clinical comprehensive evaluation of drugs in China has made rapid progress under the guidance of national policies. However, there are still issues and challenges such as incomplete evaluation methods and standards, few cases of evaluation results being converted into decision-making, and a lack of quality control mechanisms. It is suggested that standardized evaluation paths and quality control mechanisms should be explored; when the evidence-based basis is insufficient, real-world research should be conducted as much as possible, so as to accelerate the policy transformation of evaluation results.

OBJECTIVE To observe the effects of Modified shaoyao gancao decoction on intestinal transit function, intestinal flora and the contents of metabolites [γ aminobutyric acid (GABA) and 5-hydroxytryptamine (5-HT)] in slow transit constipation (STC) rats. METHODS SD rats were randomly divided into blank group (10 rats) and modeling group (30 rats), with half male and half female. The STC model was established by intragastric administration of Compound diphenoxylate tablets in the modeling group. The successfully modeled rats were randomly divided into model group, Modified shaoyao gancao decoction group [56 g/(kg·d), calculated by crude drug] and positive control group [lactulose 2.09 g/(kg·d)], with 10 rats in each group. Each administration group was given relevant medicine intragastrically, the blank group and model group received an equivalent volume of normal saline, once a day, for 14 consecutive days. During the experiment, the general situation of rats was observed in each group. After the last medication, the body weight was measured, and the Bristol score was used to evaluate the fecal characteristics. The fecal moisture content, intestinal propulsion rate, and the contents of GABA and 5-HT in intestinal content were detected; the diversity of intestinal flora in intestinal contents was investigated, and the correlation between the contents of GABA, 5-HT and relative abundance of microbiota was analyzed. RESULTS Compared with the model group, general conditions such as small body shape, sparse and rough fur, and slow movement were all improved in Modified shaoyao gancao decoction body weight, Bristol score, fecal moisture content,intestinal propulsion rate, 5-HT content, Chao1 index and Shannon index were increased significantly, while GABA content and Simpson index were decreased significantly (P<0.05). The intestinal flora of rats in the Modified shaoyao gancao decoction group could be classified as the same as the blank group, but was far from the model group; the relative abundances of Desulfobacterota, Firmicutes and Bacteroidota in this group showed a tendency of pull back, but the differences were not statistically significant compared to model group (P>0.05). Desulfobacterota was an intergroup differential factor (P<0.05). The content of GABA was negatively correlated with the relative abundance of Bacteroidota, Cyanobacteria, Patescibacteria and Actinobacteriota (P<0.05). The content of 5-HT was positively correlated with the relative abundance of Campilobacterota (P<0.05). CONCLUSIONS Modified shaoyao gancao decoction can improve the fecal properties and intestinal motility of STC rats. Its mechanism may be related to improving intestinal flora and then affecting the contents of GABA and 5-HT in intestinal contents. In addition, the contents of GABA and 5-HT may be significantly correlated with the relative abundance of specific bacterial phyla such as Bacteroidota and Campilobacterota.

ObjectiveTo explore the potential mechanism of Xiezhuo Jiedu prescription in regulating autophagy in the treatment of ulcerative colitis (UC) by bioinformatics and animal experiments. MethodsThe differentially expressed genes (DEGs) in the colonic mucosal tissue of UC patients was obtained from the Gene Expression Omnibus (GEO), and those overlapped with autophagy genes were obtained as the differentially expressed autophagy-related genes (DEARGs). DEARGs were imported into Metascape and STRING, respectively, for gene ontology/Kyoto Encyclopedia of Genes and Genomics (GO/KEGG) enrichment analysis and protein-protein interaction (PPI) analysis. Finally, 15 key DEARGs were obtained. The core DEARGs were obtained by least absolute shrinkage and selection operator (LASSO) regression and receiver operating characteristic curve (ROC) analysis. The CIBERSORT deconvolution algorithm was used to analyze the immunoinfiltration of UC patients and the correlations between core DEARGs and immune cells. C57BL/6J mice were assigned into a normal group and a modeling group. The mouse model of UC was established by free drinking of 2.5% dextran sulfate sodium. The modeled mice were assigned into low-, medium-, and high-dose Xiezhuo Jiedu prescription and mesalazine groups according to the random number table method and administrated with corresponding agents by gavage for 7 days. The colonic mucosal morphology was observed by hematoxylin-eosin staining. The protein and mRNA levels of cysteinyl aspartate-specific proteinase 1 (Caspase-1), cathepsin B (CTSB), C-C motif chemokine-2 (CCL2), CXC motif receptor 4 (CXCR4), and hypoxia-inducing factor-1α (HIF-1α) in the colon tissue were determined by Western blot and real-time fluorescence quantitative polymerase chain reaction, respectively. ResultsThe dataset GSE87466 was screened from GEO and interlaced with autophagy genes. After PPI analysis, LASSO regression, and ROC analysis, the core DEARGs (Caspase-1, CCL2, CTSB, and CXCR4) were obtained. The results of immunoinfiltration analysis showed that the counts of NK cells, M0 macrophages, M1 macrophages, and dendritic cells in the colonic mucosal tissue of UC patients had significant differences, and core DEARGs had significant correlations with these immune cells. This result, combined with the prediction results of network pharmacology, suggested that the HIF-1α signaling pathway may play a key role in the regulation of UC by Xiezhuo Jiedu prescription. The animal experiments showed that Xiezhuo Jiedu prescription significantly alleviated colonic mucosal inflammation in UC mice. Compared with the normal group, the model group showed up-regulated protein and mRNA levels of caspase-1, CCL2, CTSB, CXCR4, and HIF-1α, which were down-regulated after treatment with Xiezhuo Jiedu prescription or mesalazine. ConclusionCaspase-1, CCL2, CTSB, and CXCR4 are autophagy genes that are closely related to the onset of UC. Xiezhuo Jiedu prescription can down-regulate the expression of core autophagy genes to alleviate the inflammation in the colonic mucosa of mice.

ObjectiveTo explore the dose-effect relationship and safety of high, medium, and low doses of raw Astragali Radix in the modified Huangqi Chifengtang (MHCD) for treating proteinuria in immunoglobulin A (IgA) nephropathy, and to provide scientific evidence for the clinical use of high-dose Astragali Radix in the treatment of proteinuria in IgA nephropathy. MethodsA total of 120 patients with IgA nephropathy, diagnosed with Qi deficiency and blood stasis combined with wind pathogen and heat toxicity, were randomly divided into a control group and three treatment groups. The control group received telmisartan combined with a Chinese medicine placebo, while the treatment groups were given telmisartan combined with MHCD containing different doses of raw Astragali Radix (60, 30, 15 g). Each group contained 30 patients, and the treatment period was 12 weeks. Changes in 24-hour urinary protein (24 hUTP), traditional Chinese medicine (TCM) syndrome scores, effective rate, and renal function were observed before and after treatment. Safety was assessed by monitoring liver function and blood routine. ResultsAfter 12 weeks of treatment, 24 hUTP significantly decreased in the high, medium, and low-dose groups, as well as the control group (P<0.05, P<0.01). The TCM syndrome scores in the high, medium, and low-dose groups also significantly decreased (P<0.01). Comparisons between groups showed that the 24 hUTP in the high-dose group was significantly lower than in the medium, low-dose, and control groups (P<0.05, P<0.01), and the 24 hUTP in the medium-dose group was significantly lower than in the control group (P<0.05). The TCM syndrome scores in the high and medium-dose groups were significantly lower than in the low-dose and control groups (P<0.05, P<0.01). The total effective rates for proteinuria in the high, medium, low-dose, and control groups were 92.59% (25/27), 85.19% (23/27), 60.71% (17/28), and 57.14% (16/28), respectively. The effective rates in the high and medium-dose groups were significantly higher than in the low-dose and control groups (χ2=13.185, P<0.05, P<0.01). The effective rates for TCM syndrome scores in the high, medium, low-dose, and control groups were 88.89% (24/27), 81.48% (22/27), 71.43% (20/28), and 46.43% (13/28), respectively. The efficacy of TCM syndrome scores in the high and medium-dose groups was significantly higher than in the control group (χ2=14.053, P<0.01). Compared with pre-treatment values, there was no statistically significant difference in eGFR and serum creatinine in the high and medium-dose groups. However, eGFR significantly decreased in the low-dose and control groups after treatment (P<0.05), and serum creatinine levels increased significantly in the control group (P<0.05). No statistically significant differences were observed in urea nitrogen, uric acid, albumin, total cholesterol, triglycerides, liver function, and blood routine before and after treatment in any group. ConclusionThere is a dose-effect relationship in the treatment of IgA nephropathy with high, medium, and low doses of raw Astragali Radix in MHCD. The high-dose group exhibited the best therapeutic effect and good safety profile.

ObjectiveTo establish a model that can quickly identify the aroma components in different parts of Nardostachys jatamansi, so as to provide a quality control basis for the market circulation and clinical use of N. jatamansi. MethodsHeadspace solid-phase microextraction-gas chromatography-mass spectrometry(HS-SPME-GC-MS) combined with Smart aroma database and National Institute of Standards and Technology(NIST) database were used to characterize the aroma components in different parts of N. jatamansi, and the aroma components were quantified according to relative response factor(RRF) and three internal standards, and the markers of aroma differences in different parts of N. jatamansi were identified by orthogonal partial least squares-discriminant analysis(OPLS-DA) and cluster thermal analysis based on variable importance in the projection(VIP) value >1 and P<0.01. The odor data of different parts of N. jatamansi were collected by Heracles Ⅱ Neo ultra-fast gas phase electronic nose, and the correlation between compound types of aroma components collected by the ultra-fast gas phase electronic nose and the detection results of HS-SPME-GC-MS was investigated by drawing odor fingerprints and odor response radargrams. Chromatographic peak information with distinguishing ability≥0.700 and peak area≥200 was selected as sensor data, and the rapid identification model of different parts of N. jatamansi was established by principal component analysis(PCA), discriminant factor alysis(DFA), soft independent modeling of class analogies(SIMCA) and statistical quality control analysis(SQCA). ResultsThe HS-SPME-GC-MS results showed that there were 28 common components in the underground and aboveground parts of N. jatamansi, of which 22 could be quantified and 12 significantly different components were screened out. Among these 12 components, the contents of five components(ethyl isovalerate, 2-pentylfuran, benzyl alcohol, nonanal and glacial acetic acid,) in the aboveground part of N. jatamansi were significantly higher than those in the underground part(P<0.01), the contents of β-ionone, patchouli alcohol, α-caryophyllene, linalyl butyrate, valencene, 1,8-cineole and p-cymene in the underground part of N. jatamansi were significantly higher than those in the aboveground part(P<0.01). Heracles Ⅱ Neo electronic nose results showed that the PCA discrimination index of the underground and aboveground parts of N. jatamansi was 82, and the contribution rates of the principal component factors were 99.94% and 99.89% when 2 and 3 principal components were extracted, respectively. The contribution rate of the discriminant factor 1 of the DFA model constructed on the basis of PCA was 100%, the validation score of the SIMCA model for discrimination of the two parts was 99, and SQCA could clearly distinguish different parts of N. jatamansi. ConclusionHS-SPME-GC-MS can clarify the differential markers of underground and aboveground parts of N. jatamansi. The four analytical models provided by Heracles Ⅱ Neo electronic nose(PCA, DFA, SIMCA and SQCA) can realize the rapid identification of different parts of N. jatamansi. Combining the two results, it is speculated that terpenes and carboxylic acids may be the main factors contributing to the difference in aroma between the underground and aboveground parts of N. jatamansi.

ObjectiveTo investigate the possible mechanism of Shenfuhuang Formula (参附黄配方) in prevention and treatment of epsis-associated encephalopathy from the perspective of brain genomics. MethodsC57BL/6 mice were randomly divided into sham surgery group, sepsis group, and Shenfuhuang group, with 20 mice in each group. The sepsis group and Shenfuhuang group were induced to develop sepsis by cecal ligation and puncture (CLP) procedure. At 4 hours after modelling, Shenfuhuang group were gavaged with 2.5 g/(kg·d) of Shenfuhuang Formula, 0.5 ml each time, at 12 hours intervals, for a total of 4 times after modelling. Sepsis group and sham surgery group were given 0.5 ml of purified water orally. At 48 hours after modeling, the transcriptome sequencing was used to explore the differential gene expression in the effects of Shenfuhuang Formula on the brain regions of septic mice, and real-time PCR and ELISA were later used to further validate the differential gene and proteins expression. ResultsA total of 4605 genes were differentially expressed in Shenfuhuang group compared with sepsis group, of which 2353 genes were up-regulated and 2252 genes were down-regulated. According to the results of previous publications, six key genes were screened, including serine/threonine-protein kinase (Nek1), myelin-associated glycoprotein (Mag), endothelial cell-specific tyrosine kinase receptor (Tek), a disintegrin and metalloproteinase with thrombospondin motifs 20 (Adamts20), lymphocyte antigen 86 (Ly86), and E3 ubiquitin-protein ligase (Traip). Further genetic and protein validation revealed that, compared to the sham surgery group, the mRNA levels and corresponding protein levels of Nek1, Mag, Tek, Adamts20, Ly86, and Traip in the brain tissue of septic mice significantly reduced (P<0.05). In comparison to the sepsis group, Shenfuhuang group showed significantly increased mRNA levels and corresponding protein levels of Nek1, Mag, Tek, Adamts20, Ly86, and Traip (P<0.05). ConclusionThe potential therapeutic targets of Shenfuhuang Formula for treating sepsis-associated encephalopathy may be related to the Nek1, Mag, Tek, Adamts20, Ly86, and Traip genes and their encoded proteins.
