OBJECTIVE To explore the working model and practical effectiveness of surgical pharmacists participating in the rational medication management of urology department under the background of diagnosis related groups （DRGs） payment system.METHODS In the context of DRGs， surgical pharmacists have constructed a rational drug use control model for key DRGs disease groups with a high number of urological cases in three stages： the pre stage， which includes developing perioperative drug use guidelines and implementing a rational drug use management system intervention； the mid-term stage， which includes conducting specialized evaluations in conjunction with DRGs disease groups， conducting pharmaceutical ward rounds and medical order reviews， conducting rational drug use training and science popularization； the post event stage， which includes establishing a performance evaluation system for clinical departments and surgical pharmacists， and collecting reasons why surgical physicians did not adopt surgical pharmacist recommendations. Patients who entered DRGs groups and were discharged from the urology department of Foshan Second People’s Hospital were selected as the research subjects. The changes in departmental DRGs indicators [including number of DRGs groups， total weight， case mix index （CMI）， average length of stay， time consumption index， average cost per case， cost consumption index， average drug cost per case， drug consumption index， and mortality in low- and medium-risk] were compared before pharmacist intervention （June to December 2022）， after 1 year of intervention （June to December 2023）， and after 2 years of intervention （June to December 2024）. The improvement in medication rational rates （for antibiotics， hemocoagulase， and proton pump inhibitors） and pharmacy performance assessment indicators [average drug cost per case， defined daily doses （DDDs， excluding traditional Chinese medicine）， and antibiotic use density （AUD）] in the top 5 DRGs groups by case volume were statistically analyzed. The reasons for non-adoption of medication intervention recommendations by urologists were further analyzed.RESULTS With the participation of surgical pharmacists in the rational medication management of urology department， the number of DRGs groups， total weight， and CMI in the urology department increased year by year， while the average length of stay， average cost per case， and average drug cost per case decreased year by year， there were no low- to medium-risk deaths before and after the medication management. The average drug cost per case， DDDs， and AUD in the top 5 key DRGs groups （LE15， LE13， MC15， MC13， and LK19） were significantly decreased compared with those before intervention （ P ＜0.05）. The medication rational rates （for antibiotics， hemocoagulase， and proton pump inhibitors） in the above 5 key DRGs groups were significantly increased compared with those before intervention （ P ＜0.05）. After 2 years of pharmacist intervention， the non-adoption rates of urologists for medication interventions related to antibiotics， hemocoagulase， and proton pump inhibitors were significantly lower than those after 1 year of intervention （ P ＜0.05）； the main reason for not adopting interventions related to hemocoagulase was that surgeons believed “increasing the daily dose could shorten the hemostasis course”， the main reason for not adopting interventions related to antibiotics was “postoperative elevation of inflammatory indicators necessitates prolonged treatment”.CONCLUSIONS The hospital has successfully established a model of surgical pharmacists participating in the rational medication management of urology department. This model has improved departmental DRGs indicators and pharmacy performance assessment indicators， and enhanced the medication rational rate.

Objective:To evaluate the clinical outcomes of combined complete preservation of chordal structure mitral valve replacement (C-MVR) with total anatomical arterial myocardial revascularization (TACR) in coronary patients with moderate-to-severe or severe ischemic mitral regurgitation (IMR).Methods:This is a retrospective multi-center case series study. Data were retrospectively collected from 127 patients with coronary artery disease with moderate to severe or severe IMR who received TACR with C-MVR from July 2015 to April 2024 in 13 hospitals in China. There were 90 males and 37 females, aged (56.5±10.7) years (range: 33 to 74 years). Perioperative data and follow-up data including left ventricular ejection fraction, left ventricular end-diastolic diameter, and patency rate of arterial grafts of patients were collected. Comparisons were made using paired sample t-test or χ2 test. Results:In this cohort of 127 patients, 67 underwent concurrent tricuspid valve repair. During surgery, 113 grafts of the left internal mammary artery (LIMA), 127 grafts of the left radial artery, 80 grafts of the right radial artery, and 110 grafts of the right internal mammary artery (RIMA) were harvested. The number of the distal anastomosis was 4.2±0.4 (range: 3 to 5). The aortic cross-clamp time and cardiopulmonary bypass time were (97.5±23.4) minutes (range: 90 to 161 minutes) and (145.4±19.2) minutes (range: 101 to 210 minutes), respectively. There was one operative death. Intraoperative placement of an intra-aortic balloon pump was performed in 21 patients to improve the left ventricular ejection. No sternal ischemic occurred. All patients completed follow-up, with a mean follow-up period of (64.3±7.5) months (range: 4 to 110 months). No major cerebrovascular events occurred during the follow-up period, and all patients survived. Left ventricular ejection fraction improved postoperatively (55.0%±5.3% vs. 41.0%±15.3%, t=17.23, P<0.01). The proportion of patients with New York Heart Association functional class ≤2 increased postoperatively (23.6% (30/127) vs. 87.3% (110/126), χ2=103.77, P<0.01). The proportion of patients with Canadian Cardiovascular Society Angina Classification ≤3 decreased postoperatively (4.8% (6/126) vs. 78.7% (100/127), χ2=142.19, P<0.01). The left ventricular end-diastolic diameter decreased postoperatively ((5.70±4.50) cm vs. (6.10±0.23) cm, t=12.15, P<0.01). Coronary multi-detector computed tomography angiography (MDCTA) follow-up was conducted for (60.5±11.7) months (range: 6 to 109 months) postoperatively. MDCTA confirmed the patency rates of the grafts: 96.4% (108/112) for the LIMA grafts, 88.9% (112/126) for the left radial artery grafts, 93.7% (74/79) for the right radial artery grafts, and 90.9% (100/110) for the free RIMA grafts. No significant differences in graft patency rates were observed between the arterial grafts ( χ2=5.24, P=0.155). Conclusion:The results of this multi-centre study demonstrate satisfactory mid-term results of C-MVR with TACR for the treatment of coronary artery disease with moderate to severe or severe IMR.

Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

Objective To explore the traditional Chinese medicine(TCM)syndrome characteristics of patients with Chikungunya hemorrhagic fever and to provide empirical data to support the application of TCM in diagnosing and treating Chikungunya hemorrhagic fever.Methods A cross-sectional survey was conducted to collect clinical data(sex,age,days since onset,and comorbidity underlying disease conditions)and TCM with four-examination information(symptoms,tongue manifestations,and pulse manifestations)from 255 patients with Chikungunya hemorrhagic fever who visited Lecong Hospital of Shunde,Foshan,the Third People's Hospital of Shunde District of Foshan,Shunde Hospital of Southern Medical University Affiliated Chencun Hospital between July 23 and July 29,2025.Factor and cluster analyses were used to summarize TCM syndrome characteristics and analyze core pathogenesis in conjunction with clinical features.Results Among the 255 patients with Chikungunya hemorrhagic fever,131 were male and 124 were female,with a age of(49.05±17.93)years and a disease duration of(3.26±1.78)days.Among the four types of examination information in TCM,35 items exhibited a frequency exceeding 10%.The most prevalent symptoms were arthralgia(180 patients,70.59%),exanthem(153 patients,60.00%),fatigue(99 patients,38.82%),anhidrosis(98 patients,38.43%),pruritus(96 patients,37.65%),and fever(92 patients,36.08%).Tongue and pulse manifestations were primarily white fur(155 patients,60.78%),pink tongue(111 patients,43.53%),slippery pulse(143 patients,56.08%),and greasy fur(134 patients,52.53%).Patients with disease onset≤3 d had a higher incidence of arthralgia,fatigue,fever,aversion to cold,generalized muscle pain,aversion to wind,insomnia,headache,sweating,low-grade fever,poor appetite,loose stool,hyperhidrosis,and red tongue than those with disease onset≥4 d(P<0.05).Patients with disease onset≥4 d had a higher incidence of pink tongue and thick fur than those with disease onset≤3 d(P<0.05).The syndrome elements in patients with Chikungunya hemorrhagic fever predominantly manifested on the defensive exterior,with involvement of the sinew-bone joints,skin-muscle,and spleen.Pathogenic factors were primarily characterized by external winds,dampness,and heat.Factor and cluster analysis result indicated three TCM pathogenesis progression patterns:imbalance of the defensive exterior with wind-dampness conflict and heat transformation;dampness-heat flowing into muscles and meridians causing joint obstruction and qi blood stasis;and dampness-heat congelation resulting in qi mechanism obstruction,consumption of body fluids,and infiltration of the skin.Conclusion Patients with Chikungunya hemorrhagic fever primarily present with fever,joint pain,and rashes.In TCM,this condition falls under the category of"dampness-warmth"syndrome.Its etiology is attributed to pathogens,with transmission occurring through mosquito bites.The core pathogenesis of TCM is the invasion of the defensive exterior and dampness-toxic heat accumulation.The therapeutic principles focus on clearing heat pathogens,resolving dampness pathogens,dispersing wind pathogens,and promoting the resolution of rashes.

Objective:To establish a clinical laboratory diagnostic pathway for hepatitis C covering diagnosis, differential diagnosis, drug toxicity monitoring, and therapeutic and prognostic evaluation, and to explore a new teaching model for laboratory diagnostics based on the clinical laboratory diagnostic pathway.Methods:According to the clinical diagnosis and treatment guidelines for hepatitis C, laboratory testing strategies for different stages of diagnosis and treatment of the disease were formulated to establish a clinical laboratory diagnostic pathway for hepatitis C. The pathway was applied in the teaching for undergraduate medical students of the seven-year program of grade 2019 of The First Clinical College of Wuhan University, with those of grade 2018 as the control to receive traditional teaching. The teaching effect was compared through questionnaires and quizzes in class. The data were analyzed through the t test with the use of SPSS 19.0. Results:A clinical laboratory diagnostic pathway for hepatitis C recognized by clinicians was established, covering the entire process of clinical diagnosis, differential diagnosis, monitoring of drug side effects, and therapeutic and prognostic evaluation. The students of grade 2019 receiving the pathway-based teaching model had significant improvements in teaching quality evaluation indicators ( P<0.05), with the most marked improvement in "having mastered the key and difficult points of this lesson", with a score of (60.90±2.15) points for grade 2018 and (84.80±3.44) points for grade 2019. The total score for teaching evaluation was significantly higher in students of grade 2019 than in those of grade 2018 [(94.02±4.29) vs. (79.21±3.68)] points, P<0.05). Grade 2019 also had a significantly higher classroom quiz score than grade 2018 (94.60±5.63) vs. (78.10±4.92), P<0.01]. Conclusions:We established and applied a clinical laboratory diagnostic pathway of hepatitis C in the teaching model of laboratory diagnostics, which organically integrates laboratory diagnostics and clinical medicine, and significantly improves the quality of teaching.
