OBJECTIVE To comprehensively evaluate the quality of adverse drug reaction （ADR） reports in clinical departments or ward （hereinafter referred to as “department”） based on game theory combinatorial weighting-technique for order preference by similarity to ideal solution （TOPSIS）-rank-sum ratio （RSR） method， providing a reference for the further standardization of ADR reporting. METHODS Based on relevant documents and scoring criteria， the ADR report quality evaluation standards previously developed by our team were modified. Using game theory principles， the fusion of subjective and objective weights for each indicator was determined. A game theory combinatorial weighting-TOPSIS-RSR model was developed to evaluate and categorize the quality of raw ADR reports submitted by departments to the pharmacy department at Bozhou Hospital of Anhui Medical University. RESULTS A total of 222 ADR reports from 23 departments were included. The game theory combinatorial weighting method identifies weak points in management， such as ADR symptoms and signs， the description of underlying diseases， timing of ADR， by optimizing the weightings of the indicators. The TOPSIS-RSR method calculates that the mean relative closeness of the departments was 0.401 7， indicating that the overall report quality ranged from moderate to substandard. 20095） Three departments， including neurosurgery， demonstrated medium reporting quality [estinate closeness （Ĉ）i ≥0.506]， while two departments， such as the respiratory department，were rated as unqualified （Ĉi＜0.278）. The remaining departments were all deemed qualified （0.278≤ Ĉi＜0.506）. CONCLUSIONS The developed game theory combinatorial weighting-TOPSIS-RSR method provides an effective approach for the quality evaluation of ADR reports， which not only balances subjective and objective weights but also facilitates comparisons among different departments. There is still room for improvement in the ADR report quality at the hospital.

Increasing evidence showed that histone deacetylase 6 (HDAC6) dysfunction is directly associated with the onset and progression of various diseases, especially cancers, making the development of HDAC6-targeted anti-tumor agents a research hotspot. In this study, artificial intelligence (AI) technology and molecular simulation strategies were fully integrated to construct an efficient and precise drug screening pipeline, which combined Voting strategy based on compound-protein interaction (CPI) prediction models, cascade molecular docking, and molecular dynamic (MD) simulations. The biological potential of the screened compounds was further evaluated through enzymatic and cellular activity assays. Among the identified compounds, Cmpd.18 exhibited more potent HDAC6 enzyme inhibitory activity (IC₅₀ = 5.41 nM) than that of tubastatin A (TubA) (IC₅₀ = 15.11 nM), along with a favorable subtype selectivity profile (selectivity index ≈ 117.23 for HDAC1), which was further verified by the Western blot analysis. Additionally, Cmpd.18 induced G2/M phase arrest and promoted apoptosis in HCT-116 cells, exerting desirable antiproliferative activity (IC₅₀ = 2.59 μM). Furthermore, based on long-term MD simulation trajectory, the key residues facilitating Cmpd.18's binding were identified by decomposition free energy analysis, thereby elucidating its binding mechanism. Moreover, the representative conformation analysis also indicated that Cmpd.18 could stably bind to the active pocket in an effective conformation, thus demonstrating the potential for in-depth research of the 2-(2-phenoxyethyl)pyridazin-3(2H)-one scaffold.

AIM: To explore the intervention effect of Dahuangtang pellets (DHT) on diabetic nephropathy (DN) based on the AMP-activated protein kinase/mammalian target of rapamycin/unc-51-like kinase 1 (AMPK/mTOR/ULK1) signaling pathway. METHODS: Eight mice were randomly assigned to the model group, the dapagliflozin group, and the DHT (high, medium, and low dosage) group out of a total of 40 C57BL/KSJ-db/db (hereafter referred to as db/db) mice; another 10 C57BL/KSJ-db/dm mice were used as the normal group, saline was provided to the normal and model groups, and the mice in the treatment group received the appropriate medications. The medications were given for 10 consecutive weeks, once per day, to the mice in the treatment group. At weeks 0, 4, 8, and 10 of administration, fasting blood glucose (FBG) was assessed by drawing blood at a predetermined time from the tail vein; Urine samples were taken at 0, 5, and 10 weeks after treatment to evaluate the levels of albumin and creatinine, and the urinary albumin-creatinine ratio (ACR) was computed. After 10 weeks, mice in each group were assayed for 24 h total urine protein, serum creatinine (Scr), urea nitrogen (BUN) levels; Western blotting analysis was conducted to detect the expression of p-AMPK, p-mTOR, and p-ULK1, as well as the expression of autophagy related proteins homolog of yeast Atg6 (Beclin-1), autophagy-related proteins microtubule-associated protein 1 light chain 3 (LC3), P62 in renal tissue; Immunohistochemistry was used to measure the expression of podocyte lacunar membrane proteins (Nephrin, Podocin) in renal tissues; The pathological morphology of renal tissue was observed by light microscopy and transmission electron microscopy. RESULTS: Compared with the model group, FBG, ACR, and 24 h total urine protein were reduced in the dapagliflozin group and DHT groups of mice, and there was no statistically significant difference in Scr and BUN; In renal tissues, there is increased expression of p-AMPK and p-ULK1, decreased expression of p-mTOR, increased expression of LC3II / LC3I and Beclin-1, and decreased expression of P62 (P<0.01, P< 0.05); differentially upregulated in glomeruli are the podocyte lacunar membrane proteins Nephrin and Podocin (P<0.01, P<0.05); renal pathologic damage was reduced to varying degrees; transmission electron microscopy showed an increase in the number of autophagic vesicles and autophagic lysosomes. CONCLUSION: DHT can delay the development of DN by regulating the AMPK / mTOR / ULK1 signaling pathway, enhancing podocyte autophagy, and protecting glomeruli.

Objective:To analyze and clarify the clinical and pathogenic gene variation and genetic etiology of polycystic liver disease.Methods:The proband clinical data and family history were collected. Whole-exome sequencing technology was used to detect the proband gene variations. Fluorescence quantitative PCR validation was performed on the proband and his family to screen out pathogenic gene variation.Results:A multiple liver cyst was found in an 18-year-old male proband during a physical examination. There were no abnormalities in his liver function, and both his father and grandfather had multiple liver cysts without any obvious discomfort or other special manifestations. Whole exome sequencing suggested a heterozygous deletion in exon 1 (Exon 1) of the SEC63 gene in the proband. Real-time fluorescence quantitative PCR confirmed that the heterozygous deletion variation of the SEC63 gene Exon 1 of the proband came from his father, and the same heterozygous deletion was detected in his grandfather. The gene variant had a pathogenic variation that had been rarely reported before and was in accordance with the the American college of Medical Genetics and Genomics (ACMG) guidelines.Conclusions:The genetic etiology of this autosomal dominant polycystic liver disease has been clarified, and the heterozygous deletion of Exon1 of the SEC63 gene is a newly discovered gene variation that broadens the variation spectrum of the SEC63 gene.

ObjectiveTo validate the alleviating effect of Gegen Qinliantang （GGQLT） on insulin resistance in db/db diabetic mice by regulating the silent information regulator 1 （SIRT1）/forkhead transcription factor O1 （FoxO1） autophagy pathway. MethodSeventy-five SPF-grade spontaneous type 2 diabetic db/db mice and 15 control db/m mice were selected and maintained on regular feed for one week before measuring blood glucose. They were randomly divided into six groups， with 15 mice in each group. The groups included a normal group （physiological saline， 0.2 g·kg^-1）， a metformin group （0.2 g·kg^-1）， high-， medium-， and low-dose GGQLT groups （31.9， 19.1， 6.9 g·kg^-1）， and a model group （physiological saline， 0.2 g·kg^-1）. They were orally treated with corresponding drugs for eight weeks， once daily. Fasting blood glucose （FBG） was measured using a Roche glucometer. Serum levels of high-density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， triglyceride （TG）， and total cholesterol （TC） were measured using an automated biochemical analyzer. Fasting serum insulin （INS） levels were determined using enzyme-linked immunosorbent assay （ELISA）， and the homeostasis model assessment of insulin resistance （HOMA-IR） was calculated. Western blot was used to detect the expression of Beclin-1， microtubule-associated protein 1 light chain 3 （LC3）， and SIRT1/FoxO1 autophagy pathway-related proteins in liver tissues. Immunohistochemistry was performed to assess the expression of SIRT1， FoxO1， Beclin-1， and LC3B proteins in liver tissues. Transmission electron microscopy was used to observe the formation of autophagosomes in the liver. ResultCompared with the normal group， the model group showed significant increases in FBG， FINS， HOMA-IR， TC， TG， LDL-C， and HDL-C levels （P<0.01）， and significant increases in the expression of SIRT1， Beclin-1， LC3， and FoxO1 proteins in liver tissues （P<0.01）. Transmission electron microscopy revealed the highest number of autophagosomes in the model group. Compared with the model group， the metformin group and the low-， medium-， and high-dose GGQLT groups showed significant decreases in serum FBG， FINS， HOMA-IR， TC， TG， LDL-C， and HDL-C levels （P<0.05， P<0.01）， significant decreases in the expression of SIRT1， Beclin-1， LC3 （P<0.05， P<0.01）， and up-regulated FoxO1 protein （P<0.01）. Transmission electron microscopy showed a reduction in the degree of autophagy in the treatment groups. Compared with the metformin group， the medium- and high-dose GGQLT groups showed significant decreases in FBG， FINS， and TG levels （P<0.01）， significant decreases in the expression of SIRT1， Beclin-1， and LC3 in liver tissues （P<0.05， P<0.01）， and reduced FoxO1 protein （P<0.01）. The high-dose GGQLT group showed reduced HOMA-IR， TC， LDL-C， and HDL-C levels （P<0.05， P<0.01）. Transmission electron microscopy revealed a significant reduction in autophagosomes in the medium- and high-dose GGQLT groups. ConclusionGGQLT can significantly improve glucose and lipid metabolism disorders， alleviate insulin resistance in db/db mice， and prevent and treat type 2 diabetes by activating the SIRT1/FoxO1 autophagy pathway.

ObjectiveTo investigate the changes of intestinal microbiota in type 2 diabetic diarrhea （T2DD） patients with dampness-heat syndrome and spleen-kidney deficiency syndrome. MethodT2DD patients who were admitted to the Department of Endocrinology Ⅰ of the Affiliated Hospital of Shaanxi University of Chinese Medicine from March 2020 to May 2021 were selected， including 14 patients with type 2 diabetes mellitus （T2DM）， 12 T2DD patients with dampness-heat syndrome， and 13 T2DD patients with spleen-kidney deficiency syndrome. Twelve healthy subjects receiving medical examination were selected as control group. Their body mass index （BMI）， fasting plasma glucose （FPG）， 2 h postprandial blood glucose （2 h PBG） and glycosylated hemoglobin （HbA1c） were compared. Fecal samples were collected for DNA extraction to build a database. High-throughput 16S rDNA sequencing was used to compare the composition of intestinal microbiota and the differential bacteria among the four groups. ResultCompared with the conditions in control group， the levels of FPG， 2 h PBG and HbA1c in the other groups were increased （P<0.05）. Alpha diversity showed no significant difference in species richness， evenness and diversity of intestinal microbiota among the groups. Beta diversity indicated that intestinal microbiota tended to be consistent in each group， and there was no marked difference between groups. The top 5 phylum by relative abundance were Bacteroidetes，Proteobacteria， Firmicutes， Actinobacteria， and Fusobacteria， among which，Bacteroidetes， Proteobacteria and Firmicutes were dominant. Compared with the control group， the three diabetic groups had elevated relative abundance of Bacteroidetes while decreased relative abundance of Firmicutes. The relative abundance of Actinomycetes in spleen-kidney deficiency T2DD group was significantly higher than that in the other groups， and the relative abundance of Firmicutes and Fusobacteria in the dampness-heat T2DD group was significantly lower than that in the other groups. At the genus level， the top 10 bacteria by relative abundance were Phocaeicola， Bacteroides， Pseudescherichia， Prevotella， Bifidobacterium， Faecalibacterium， Fusobacterium， Roseburia， Citrobacter， and Cetobacterium. LEfSe analysis revealed that the relative abundance of Prevotella， Mediterraneibacter， Parabacteroides， and Fusicatenibacter in diabetic patients was remarkably higher than that in healthy patients. Bacteroides and Sutterella might be the characteristic microbiota of T2DD patients with dampness-heat syndrome， while Faecalibacterium， Limosilactobacillus， Eubacterium， Gemmiger， Enterocloster， Alistipes， Parasutterella and Oscillibacter might be the characteristic microbiota of T2DD patients with spleen-kidney deficiency syndrome. ConclusionBacteroides and Parasutterella might be the characteristic microbiota of T2DD patients with dampness-heat syndrome and spleen-kidney deficiency syndrome， respectively. This paper provided reference for studying the mechanism， diagnosis and treatment of modern traditional Chinese medicine for T2DD of dampness-heat type and spleen-kidney deficiency type.

This article reported the genetic etiology of two pedigrees with Alstrom syndrome and the results of prenatal genetic diagnosis in the second pregnancies of the two pedigrees. The probands in the two pedigrees both had different degrees of visual abnormalities. The mothers of the two probands were pregnant again and received prenatal diagnosis in the First Affiliated Hospital of Zhengzhou University. Whole-exome sequencing and Sanger sequencing confirmed that the proband of pedigree 1 carried compound heterozygous variants of c.6103C>T(p.Gln2035*) and c.6430C>T(p.Arg2144*) in ALMS1 gene, and the parents were carriers. While the proband of pedigree 2 was found to carry compound heterozygous variants of c.9148_9149delCT(p.Cys3051Serfs*9) and c.12028delC(p.Leu4010Typfs*19) in ALMS1 gene and the parents were also carriers. Among these variants, c.6103C>T(p.Gln2035*), c.9148_9149delCT(p.Cys3051Serfs*9) and c.12028delC(p.Leu4010Typfs*19) were all de novo ones. Prenatal genetic detection confirmed the fetus of pedigree 1 carried c.6430C>T(p.Arg2144*) variant inherited from the father and the pregnancy was continued after genetic counselling, while the fetus of pedigree 2 was found to carry both of the same variants as the proband and the pregnancy was terminated.
