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.

Objective::To compare the analgesic effects of ibuprofen administered orally via two modes combined with a conventional, patient-controlled intravenous analgesia pump on maternal pain after cesarean section (CS).Methods::This prospective, randomized, controlled study enrolled females who underwent CS from August 2022 to August 2023 at Peking University First Hospital, Beijing, China. Participants were randomly assigned to either an as-needed ibuprofen group (300 mg orally upon request) or a scheduled ibuprofen group (300 mg every 12 hours for 48 hours). The primary outcomes assessed were postoperative pain levels using the Wong-Baker Faces Pain Scale-Revised and cumulative oxycodone consumption at multiple time points up to 48 hours post-delivery. Secondary outcomes included recovery parameters (time to first flatus, ambulation, and lactation initiation), patient satisfaction with pain control, and postpartum depression scores evaluated by the Edinburgh Postnatal Depression Scale on postoperative day 3. Normally distributed data analyzed with t-tests; non-normal data with Mann-Whitney U tests; categorical variables with chi-square or Fisher’s exact tests (SPSS 26.0, P < 0.05). Results::After excluding 61 non-eligible cases, 339 patients were included (171 as-needed vs. 168 scheduled). The scheduled group showed significantly better pain control at 12 hours (4.00 (2.00-5.50) vs. 4.00 (4.00-6.00), P < 0.001), 24 hours (4.00 (2.00-4.00) vs. 4.00 (2.00-6.00), P < 0.001), and 36 hours (2.00 (2.00-4.00) vs. 4.00 (2.00-4.00), P < 0.001), and 48 hours (2.00 (2.00-4.00) vs. 2.00 (2.00-4.00), P = 0.004) post-delivery and lower levels of oxycodone consumption at 36 hours (10.20 (8.20-13.35) vs. 11.00 (8.80-14.40), P = 0.042) and 48 hours (12.40 (10.40-15.95) vs. 13.80 (11.00-16.00), P = 0.020) postpartum compared with those in the as-needed group. Additionally, the time to the return of bowel movements was shorter in the scheduled group than in the as-needed group (23.50 (16.94, 31.47) vs. 27.00 (19.88, 35.97), P = 0.004). Differences in post-delivery ambulation, lactation initiation, satisfaction levels, and depression scores were not significantly different between the two groups. Conclusion::The results of this study promote the use of ibuprofen (scheduled oral administration) combined with a conventional, patient-controlled intravenous analgesia pump for achieving better post-CS pain control than an as-needed dosage regimen.Registration::Chinese Clinical Trial Registry, ChiCTR2400082474.

OBJECTIVE: This study aimed to investigate the impact of glycemic control and diabetes duration on subsequent myocardial infarction (MI) in patients with both coronary heart disease (CHD) and type 2 diabetes (T2D). METHODS: We conducted a retrospective cohort study of 33,238 patients with both CHD and T2D in Shenzhen, China. Patients were categorized into 6 groups based on baseline fasting plasma glucose (FPG) levels and diabetes duration (from the date of diabetes diagnosis to the baseline date) to examine their combined effects on subsequent MI. Cox proportional hazards regression models were used, with further stratification by age, sex, and comorbidities to assess potential interactions. RESULTS: Over a median follow-up of 2.4 years, 2,110 patients experienced MI. Compared to those with optimal glycemic control (FPG < 6.1 mmol/L) and shorter diabetes duration (< 10 years), the fully-adjusted hazard ratio ( HR) (95% Confidence Interval [95% CI]) for those with a diabetes duration of ≥ 10 years and FPG > 8.0 mmol/L was 1.93 (95% CI: 1.59, 2.36). The combined effects of FPG and diabetes duration on MI were largely similar across different age, sex, and comorbidity groups, although the excess risk of MI associated with long-term diabetes appeared to be more pronounced among those with atrial fibrillation. CONCLUSION Our study indicates that glycemic control and diabetes duration significant influence the subsequent occurrence of MI in patients with both CHD and T2D. Tailored management strategies emphasizing strict glycemic control may be particularly beneficial for patients with longer diabetes duration and atrial fibrillation.

BACKGROUND: Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by chronic inflammation and joint destruction. Iguratimod (IGU) is a novel conventional synthetic disease-modifying antirheumatic drugs (csDMARD) with good efficacy and safety for the treatment of active RA in China and Japan. However, the long-term effects of IGU on the progression of bone destruction or radiographic progression in patients with active RA remain unknown. We aimed to investigate the efficacy and safety of iguratimod (IGU), a combination of methotrexate (MTX) and IGU, and IGU in patients with active rheumatoid arthritis (RA) who were naïve to MTX. METHODS: This multicenter, double-blind, randomized, non-inferiority clinical trial was conducted at 28 centers for over 52 weeks in China. In total, 911 patients were randomized (1:1:1) to receive MTX monotherapy (10-15 mg weekly, n = 293), IGU monotherapy (25 mg twice daily, n = 297), or IGU + MTX (10-15 mg weekly for MTX and 25 mg twice daily for IGU, n = 305) for 52 weeks. The patients' clinical characteristics, Simplified Disease Activity Index (SDAI), Clinical Disease Activity Index (CDAI), disease activity score in 28 joints-C-reactive protein (DAS28-CRP) level, and disease activity score in 28 joints-erythrocyte sedimentation rate (DAS28-ESR) were assessed at baseline. The primary endpoints were the proportion of patients with ≥20% improvement according to the American College of Rheumatology (ACR20) response and changes in the van der Heijde-modified total Sharp score (vdH-mTSS) at week 52. RESULTS: The proportions of patients achieving an ACR20 response at week 52 were 77.44%, 77.05 %, and 65.87% for IGU monotherapy, IGU + MTX, and MTX monotherapy, respectively. The non-inferiority of IGU monotherapy to MTX monotherapy was established with the ACR20 (11.57%; 95% confidence interval [CI], 4.35-18.79%; P <0.001) and vdH-mTSS (-0.37; 95% CI, -1.22-0.47; P = 0.022). IGU monotherapy was also superior to MTX monotherapy in terms of ACR20 ( P = 0.002) but not the vdH-mTSS. The superiority of IGU + MTX over MTX monotherapy was confirmed in terms of the ACR20 (11.18%; 95% CI, 3.99-18.37%; P = 0.003), but not in the vdH-mTSS (-0.68; 95% CI, -1.46-0.11; P = 0.091). However, the difference in the incidence rates of adverse events was not statistically significant. CONCLUSIONS: IGU monotherapy/IGU + MTX showed a more favorable clinical response than did MTX monotherapy. IGU may have some clinical benefits over MTX in terms of radiographic progression, implying that IGU may be considered as an initial therapeutic option for patients with active RA.

Recent studies have shown that an imbalance in iron metabolism can affect the composition and microstructural changes of bone, disrupting bone homeostasis and leading to osteoporosis(OP). The imbalance in iron metabolism, along with its induced local abnormal microenvironment and cellular iron death, has become a new focal point in OP research, drawing increasing attention from the academic community regarding the regulation of iron metabolism to prevent and manage OP. From the perspective of traditional Chinese medicine(TCM), iron metabolism imbalance has potential connections to TCM theories regarding internal organs, as well as treatments aimed at tonifying the kidney, strengthening the spleen, and activating blood circulation. Evidence is continually emerging that TCMs and effective components that tonify the kidney, strengthen the spleen, and activate blood circulation can prevent and manage OP by regulating iron metabolism. This article analyzes the relationship between iron and bone, as well as the effects of TCM formulations on improving iron metabolism and influencing bone metabolism, from the perspectives of iron metabolism mechanisms and TCM interventions, aiming to broaden existing clinical strategies for prevention and treatment and inject new momentum into the field of OP as it moves into a new era.

Objective: To identify the risk factors for pulmonary arterial hypertension(PAH) in maintenance peritoneal dialysis(MPD) patients and to develop and validate a nomogram-based risk-prediction model. Methods: A total of 168 hospitalized MPD patients from the Department of Nephrology were enrolled.Body-fluid composition was measured by bioelectrical impedance analysis,and pulmonary-artery systolic pressure(PASP) was assessed by echocardiography.Patients were randomly allocated into a training set and a validation set at 1:1 ratio.Variables with P< 0. 05 in multivariable Logistic regression in the training set were incorporated to construct a nomogram .The validation set was used to test the model ’s predictive performance . ROC curves , calibration curves , and decision-curve analysis were applied to evaluate accuracy , consistency , and clinical usefulness of the model . Results: Dialysis vintage ( OR : 1 . 038 , 95% CI: 1 . 008 - 1 . 069 , P = 0. 012) , hemoglobin level ( OR : 0. 961 , 95% CI: 0. 929 - 0. 994 , P = 0. 021) , and extracellular water/intracellular water ratio (E/I) (OR : 1 . 069 , 95% CI: 1 . 024- 1 . 115 , P = 0. 002) were independent risk factors for PAH . ROC analysis yielded area under curve as 0. 867 (95% CI: 0. 782 - 0. 953) and 0. 808 (95% CI: 0. 714 - 0. 902) in the training and validation sets , respectively .Calibration plots showed that the predicted curves for both the training and validation sets closely overlapped with the ideal reference line , indicating that the nomogram risk-prediction model had good predictive performance . Decision-curve analysis demonstrated that , within threshold ranges of 0. 13 - 0. 76 ( training set ) and 0. 20 - 0. 76 (val- idation set ) , clinical net benefit was substantial when interventions were guided by the nomogram . Conclusion Dialysis vintage , hemoglobin level , and fluid-overload index (E/I) are independent risk factors for PAH in MPD patients . The nomogram based on these parameters reliably predicts PAH risk and may aid clinical decision-making.
