OBJECTIVE To establish a Chinese drug-related problem （DRP） classification system applicable to pharmacist-led pharmaceutical care in China， providing pharmacists with an effective and practical tool for pharmaceutical care. METHODS A multi-stage process was employed to construct the DRP classification system， including literature review and analysis， comparison of existing classification systems， refinement of classification items and framework development， two rounds of standard case validation， expert discussion， and system revision. The Fleiss′ kappa test was used to calculate the consistency coefficient κ， assessing the reliability of pharmacists participating in evaluating the classification system. An electronic questionnaire comprising six items was employed to evaluate the system’s applicability. RESULTS The constructed Chinese DRP classification system comprised six sections [problem（including potential problems）， DRP evaluation， cause （including possible causes of potential problems）， intervention， acceptance of intervention and DRP status]， with 24 primary codes and 96 secondary codes. In the first round of case validation， κ values exceeded 0.4 for all sections except “intervention” and “DRP status”. In the second round， κ values exceeded 0.4 for all sections. In the applicability evaluation of the classification system， positive ratings （“strongly agree” or “agree”） exceeded 85% for all items. Specifically， positive ratings for“the classification system can provide appropriate category selection”，“ the classification system is comprehensive”，“ the classification system is convenient to use” and “the classification system is highly satisfactory” exceeded 92%. CONCLUSIONS The Chinese DRP classification system developed demonstrates both high reliability and applicability， providing an effective and practical classification tool for pharmacists in China to conduct pharmaceutical care.

Increasing evidence has underscored the significance of post-stroke alterations along gut-brain axis, while its role in pathogenesis and treatment of ischemic stroke (IS) remains largely unexplored. This study aimed to elucidate the therapeutic effects and action targets of Panax notoginseng saponins (PNS) on IS and explore a novel pathogenesis and treatment strategy of IS via profiling the microbial community and metabolic characteristics along gut-brain axis. Our findings revealed for the first time that the therapeutic effect of PNS on IS was microbiota-dependent. Ischemia/reperfusion (I/R) modeling significantly down-regulated Lactobacilli in rats, and PNS markedly recovered Lactobacilli, particularly Lactobacillus reuteri (L.Reu). Metabolomics showed a significant reduction in serum histidine (HIS) in clinical obsolete IS patients and rehabilitation period I/R rats. Meanwhile, the L.Reu colonization in I/R rats exhibited significant neuroprotective activity and greatly increased HIS in serum, gut microbiota, and brain. Moreover, exogenous HIS demonstrated indirect neuroprotective effects through metabolizing to histamine. Notably, vagus nerve severance in I/R rats was performed to investigate HIS's neuroprotective mechanism. The results innovatively revealed that PNS could promote HIS synthesis in gut by enhancing L.Reu proportion, thereby increasing intracerebral HIS through peripheral pathway. Consequently, our data provided novel insights into HIS metabolism mediated by L.Reu in the pathogenesis and treatment of IS.

Objective To analyze the influence of anxiety and depression on postoperative recovery of patients with acute coronary syndrome(ACS),and to analyze the relationship with neutrophil to lymphocyte ratio(NLR),lymphocyte to monocyte ratio(LMR)and platelet-to-lymphocyte ratio(PLR).Methods A total of 108 ACS patients undergoing surgical treatment in Hainan Provincial Anning Hospital from March 2022 to March 2024 were retrospectively recruited.According to their scores of Hamilton anxiety scale and Hamilton depression scale,they were divided into an anxiety and depression group(34 cases)and a non-anxiety and depression group(74 cases).The quality of life at 1 month after surgery and serum levels of NLR,LMR and PLR at 3 d after surgery were compared between groups.Spearman correlation analysis was performed to analyze the correlation between serum NLR,LMR and PLR and anxiety as well as depression in the ACS patients.Binary logistic regression analysis was used to construct an evaluation model with NLR,LMR and PLR as variables.Receiver operating characteristic(ROC)curve was plotted to analyze the value of serum NLR,LMR and PLR in evaluating anxiety and depression.Results At 1 month after surgery,the scores of dimensions of Short-Form 36 Questionnaire(SF-36)were significantly lower in the anxiety and depression group than the non-anxiety and depression group(P＜0.01).The levels of serum NLR and PLR at 3 d post-operatively were obviously higher while that of LMR was notably lower in the anxiety and depression group than the non-anxiety and depression group(P＜0.01).Spearman correlation analysis indicated that serum NLR and PLR levels(r=0.500,P=0.000;r=0.215,P=0.026)were positively correlated,and LMR level(r=-0.474,P=0.000)was negatively correlated with co-occurrence of anxiety and depression in the ACS patients.Binary logistic regression analysis suggested that NLR,LMR and PLR were high risk factors for anxiety and depression in ACS patients(OR=6.867,95％CI:2.792-16.887,P=0.000;OR=0.180,95％CI:0.078-0.419,P=0.000;OR=1.285,95％CI:1.038-1.591,P=0.032).ROC curve analysis showed that the AUC value of the three indicators combined together in evaluating anxiety and depression in the ACS patients was 0.900(95％CI:0.827-0.949,P=0.000),with a sensitivity of 73.53％and a specificity of 95.95％.The efficiency of combined evalu-ation was superior to that of each indicator.Conclusion Anxiety and depression can affect the postoperative recovery and serum NLR,LMR and PLR in ACS patients.Early combined detection of the three indicators can provide certain value for whether ACS patients are complicated with anxiety and depression.

Objective:To evaluate the efficacy of eculizumab in treating hematopoietic stem cell transplantation-associated thrombotic microangiopathy (TA-TMA) .Methods:This retrospective study included 11 patients who developed TA-TMA after allogeneic hematopoietic stem cell transplantation and subsequently received eculizumab treatment at Peking University People′s Hospital between June 2018 and May 2024. The incidence of TA-TMA, treatment details, and clinical outcomes were analyzed.Results:Among the 11 included patients [4 males, 7 females; median age: 29 years (range: 9-56) ], underlying diseases were severe aplastic anemia (SAA) in 5 patients, acute lymphoblastic leukemia (ALL) in 3 patients, and acute myeloid leukemia (AML) in 3 patients. The median time to TA-TMA diagnosis was 48 days post-transplantation (range: 4-213 days), and all patients met the diagnostic criteria for high-risk TA-TMA. The median interval from TA-TMA diagnosis to the initiation of eculizumab treatment was 12 days (range: 1-56 days). Patients received a median of 3 doses of eculizumab (range: 1-14). Ten of the 11 patients were assessed as having no response (NR) to eculizumab at the end of treatment or at death. One patient achieved a partial response (PR) but subsequently died after TA-TMA relapsed due to infection. At the last follow-up, all patients were either lost to follow-up or had died. The median follow-up duration was 88 days (range: 33-326 days), and the median time from TA-TMA diagnosis to the last follow-up was 31 days (range: 21-113 days) .Conclusion:Eculizumab demonstrated poor efficacy in this TA-TMA cohort. This might be attributable to the critical and complex condition of the patients, delayed initiation of eculizumab treatment, and insufficient dosage.

Objective:To investigate the efficacy and safety of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for the treatment of BCR::ABL-negative chronic neutrophilic leukemia (CNL) and MDS/MPN with neutrophilia.Methods:This study retrospectively analyzed 12 cases of CNL and MDS/MPN with neutrophilia that underwent allo-HSCT from March 2017 to June 2024, comprising 7 males and 5 females with a median age of 48 ( IQR: 28, 59) years. The 2-year overall survival (OS), disease-free survival (DFS), cumulative incidence of relapse (CIR), and transplantation-related mortality (TRM) rates were analyzed. Complications were also assessed. Results:Of the 12 patients, 6 received matched sibling HSCT and 6 received haploidentical HSCT. All patients had successful engraftment, and the median times of neutrophil and platelet engraftment were 17 ( IQR: 11, 24) days and 15 ( IQR: 9, 28) days, respectively. Grade Ⅱ–Ⅳ acute graft versus host disease (GVHD) and chronic GVHD occurred in 2 and 4 cases, respectively. The 2-year OS, DFS, CIR, and TRM rates were (65.6 ± 16.4) %, (41.7 ± 16.6) %, (47.2 ±18.2) %, and (11.1 ± 11.4) %, respectively, after a median follow-up time of 637 ( IQR: 330, 943) days. One patient died from treatment-related complications due to respiratory failure caused by coronavirus disease 2019. Two patients died due to relapse. Conclusion:Allo-HSCT can be applied as a safe and effective approach to treat CNL and MDS/MPN with neutrophilia.

Objective:To evaluate the safety and efficacy of donor-purified CD34 + stem cell boosts in patients with poor hematopoietic reconstruction (PHR) after haploid hematopoietic stem cell transplantation (haplo-HSCT) for aplastic anemia (AA) . Method:A retrospective analysis was conducted on 11 patients with AA and PHR who underwent haplo-HSCT and received donor-purified CD34 + stem cell boosts at Peking University People’s Hospital. Recovery of blood cell counts, incidence of graft-versus-host disease (GVHD), and overall survival (OS) were assessed. Results:Of the 11 patients with PHR, two were diagnosed with prolonged isolated thrombocytopenia (PT), one was primary poor graft function (PGF), and eight were diagnosed with secondary PGF. The median time to PHR diagnosis was 110 days (range: 60-330 days), and the median interval from transplantation to purified CD34 + hematopoietic stem cell infusion was 194 days (range: 125-456 days). The two patients with PT achieved complete platelet recovery at 22 and 13 days after CD34 + stem cell infusion, respectively. Among the remaining nine patients with PGF, six achieved complete hematopoietic recovery, with a median absolute neutrophil count recovery time of 19 days (8-158 days), HGB recovery time of 32.5 days (range: 13-158 days), and platelet recovery time of 31.5 days (range: 7-171 days). The incidence of chronic GVHD after infusion was 18.2%, with no cases of acute GVHD observed. The OS rate was 90.9% (10/11) in the 11 patients, with a median follow-up of 614 days (range: 153-1 765 days) . Conclusion:Donor-purified CD34 + stem cell boost may be an effective therapeutic strategy for PHR in patients with AA after haplo-HSCT.

OBJECTIVE:To assess the efficacy and safety of acupuncture in treating postmenopausal osteoporosis.METHODS:Clinical randomized controlled trials on acupuncture for postmenopausal osteoporosis were retrieved from databases including CNKI,VIP,WanFang,China Biomedical Literature Service System,Web of Science,PubMed,Embase,and Cochrane Library.The search period was from the inception of the database to July 23,2024.The quality of evidence and risk of bias of the included studies were assessed using the GRADEprofiler and the revised Cochrane risk-of-bias tool for randomized trials(RoB 2.0).Meta-analysis was performed using StataSE 15 and TSA 0.9.5,along with heterogeneity analysis,sensitivity analysis,subgroup analysis,publication bias analysis,trim-and-fill analysis,and trial sequential analysis.RESULTS:The study included 19 randomized controlled trials involving a total of 1 464 patients.(1)The meta-analysis revealed that compared with conventional therapies,acupuncture significantly increased the total effective rate(RR=1.25,95％confidence interval[1.19,1.32],P＜0.001),lumbar spine L2-L4 bone mineral density(mean difference=0.08,95％confidence interval[0.05,0.11],P＜0.001),and estrogen levels(standard mean difference=0.55,95％confidence interval[0.30,0.81],P＜0.001).Additionally,acupuncture increased bone mineral density and gonadotropin levels in the femoral neck,greater trochanter,and Ward's triangle,reduced visual analogue scale scores,and improved bone metabolism without significantly increasing the incidence of adverse events.(2)Subgroup analysis of the main outcome indicators showed no significant difference between the treatment and control groups when the body mass index was greater than 23.9 kg/m2 and the total treatment duration was 6 months.All other treatment subgroups were significantly superior to the control group.(3)Publication bias analysis indicated a significant risk of publication bias in the overall efficacy;however,a trim-and-fill analysis showed that this risk did not significantly impact the reliability of the conclusions.Publication bias analysis showed no significant risk of publication bias in the bone mineral density values of lumbar spine L2-L4 and estradiol levels.(4)The sequential analysis of the trial further confirmed that acupuncture significantly increased the overall effective rate,bone mineral density values at the lumbar spine L1-L4,and estradiol levels.CONCLUSION:Acupuncture is an effective and safe treatment for postmenopausal osteoporosis.More rigorously designed and high-quality studies are needed in the future to verify this conclusion.

Objective: To determine the clinical efficacy and mechanism of Piwei Peiyuan Pill (PPP) combined with moxibustion for treating patients with chronic atrophic gastritis (CAG) with spleen and stomach weakness syndrome. Methods: Ninety-six CAG patients with spleen and stomach weakness syndrome who met the inclusion and exclusion criteria were enrolled at the Department of Spleen and Stomach Diseases of the Second Affiliated Hospital of Anhui University of Chinese Medicine from June 2022 to December 2023. The patients were randomly divided into a control, a Chinese medicine, and a combined group using a random number table method, with 32 cases in each group (two cases per group were excluded). The control group was treated with rabeprazole combined with folic acid tablets (both thrice daily), the Chinese medicine group was treated with PPP (8 g, thrice daily), and the combined group was treated with moxa stick moxibustion (once daily) on the basis of the Chinese medicine group for 12 consecutive weeks. Gastric mucosa atrophy in the three groups was observed before and after treatment. The gastric mucosal pathological score was evaluated. The Patient Reported Outcome (PRO) scale was used to evaluate the patients′ physical and mental health status and quality of life.An enzyme-linked immunosorbent assay was used to detect serum tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-4, IL-10, IL-37, and transforming growth factor (TGF)-β levels in each group. Real-time fluorescence PCR was used to detect the relative expression levels of signal transducer and activator of transcription 3 (STAT3) and mammalian target of rapamycin (mTOR) mRNA in each group. Western blotting was used to detect the relative expression levels of proteins related to the STAT3/mTOR signaling pathway, and the adverse drug reactions and events were recorded and compared. Results: There was no statistical difference in age, gender, disease duration, family history of gastrointestinal tumors, alcohol consumption history, and body mass index among the three groups of patients.The total therapeutic efficacy rates of the control, Chinese medicine, and combined groups in treating gastric mucosal atrophy were 66.67% (20/30), 86.67% (26/30), and 90.00% (27/30), respectively (P<0.05). Compared to before treatment, the pathological and PRO scale scores of gastric mucosa in each group decreased after treatment, and TNF-α, IL-1β, IL-37, and TGF-β levels decreased. The relative STAT3 and mTOR mRNA expression levels, as well as the relative STAT3, p-STAT3, mTOR, and p-mTOR protein expression levels decreased (P<0.05), whereas the IL-4 and IL-10 levels increased (P<0.05). After treatment, compared to the control group, the pathological score of gastric mucosa, PRO scale score, TNF-α, IL-1β, IL-37, TGF-β content, relative STAT3 and mTOR mRNA expression levels, and relative STAT3, p-STAT3, mTOR, and p-mTOR protein expression levels in the Chinese medicine and combined groups after treatment were reduced (P<0.05), whereas the IL-4 and IL-10 levels increased (P<0.05). After treatment, compared to the Chinese medicine group, the combined group showed a decrease in relative STAT3, mTOR mRNA expression levels, and STAT3, p-STAT3, mTOR, and p-mTOR protein expression levels (P<0.05). Conclusion The combination of PPP and moxibustion may regulate the inflammatory mechanism of the body by inhibiting the abnormal activation of the STAT3/mTOR signaling pathway, upregulating related anti-inflammatory factor levels, downregulating pro-inflammatory factor expression, and increasing related repair factor expression, thereby promoting the recovery of atrophic gastric mucosa, reducing discomfort symptoms, and improving the physical and mental state of CAG patients with spleen and stomach weakness syndrome.

Objective : To establish an interleukin-1β (Il-1β) induced inflammatory model of rat articular chondro- cytes (ACs) , and to investigate the relationship between the expression of lysine acetyltransferase 7 (KAT7) under inflammatory stimulation and the senescence of ACs. Methods: Primary ACs were obtained by digestion of rat knee cartilage with collagenase type Ⅱ and identified. The inflammatory model of ACs was induced by IL-1β . KAT7 was over-expressed or knocked down in ACs by adeno-associated virus infection or small interfering RNA transfection , respectively. A negative control group was set up. Transwell assay was used to detect cell migration ability. Senes- cent cells were stained with senescence-associated β-galactosidase (SA-β-Gal) . Western blot ( WB) was used to detect the protein expression levels of KAT7 , collagen type II (Col Ⅱ ) , matrix metalloproteinase 13 (MMP13) , tumor protein p53 (p53) and cyclin-dependent kinase inhibitor 1A (p21) . The cells of negative control group and KAT7 over-expression group were performed for RNA sequencing , and WB was used to verify the related signaling pathways obtained by Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis. Results: Compared with the control group , the SA-β-Gal staining was enhanced , the protein expression of Col Ⅱ decreased , the pro- tein expression of MMP13 and p53 increased , the cell migration ability decreased , and the expression of KAT7 also increased in the ACs of rats after IL-1β stimulation. Compared with the negative control group , the SA-β-Gal stai- ning was enhanced , the protein expression of Col Ⅱ decreased , the protein expression of MMP13 , p53 and p21 in- creased , and the cell migration ability decreased in the KAT7 over-expression group. Compared with the negative control group , the SA-β-Gal staining was weakened , the protein expression of Col Ⅱ increased , the protein expres- sion of MMP13 , p53 and p21 decreased , and the cell migration ability was enhanced in the KAT7 knockdown inflammatory model of ACs. KEGG enrichment analysis showed that phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) signaling pathway was activated. Compared with the negative control group , the relative protein ex⁃pression levels of phosphorylated protein kinase B (p⁃AKT)/AKT and phosphorylated mammalian target of rapamy⁃cin (p⁃mTOR)/mTOR in KAT7 over⁃expression group increased. The relative protein expression levels of p ⁃AKT/AKT and p ⁃mTOR/mTOR in KAT7 knockdown cells decreased. Conclusion Rat ACs with high expression of KAT7 exhibit senescence and osteoarthritis phenotype , and the mechanism may be related to the activation of PI3K/AKT/mTOR signaling pathway by KAT7.

The NOD-like receptor protein 3(NLRP3)inflammasome is essential in innate immune-mediated inflammation,with its overactivation implicated in various autoinflammatory,metabolic,and neurode-generative diseases.Pharmacological inhibition of NLRP3 offers a promising treatment strategy for in-flammatory conditions,although no medications targeting the NLRP3 inflammasome are currently available.This study demonstrates that clioquinol(CQ),a clinical drug with chelating properties,effec-tively inhibits NLRP3 activation,resulting in reduced cytokine secretion and cell pyroptosis in both human and mouse macrophages,with a half maximal inhibitory concentration(IC50)of 0.478 μM.Additionally,CQ mitigates experimental acute peritonitis,gouty arthritis,sepsis,and colitis by lowering serum levels of interleukin-1β(IL-1β),IL-6,and tumor necrosis factor-α(TNF-α).Mechanistically,CQ covalently binds to Arginine 335(R335)in the NACHT domain,inhibiting NLRP3 inflammasome assembly and blocking the interaction between NLRP3 and its component protein.Collectively,this study identifies CQ as an effective natural NLRP3 inhibitor and a potential therapeutic agent for NLRP3-driven diseases.
