Objective To analyze the role and mechanism of Xiaoqinglong decoction in alleviating the pathological process of pulmonary arterial hypertension(PAH),and to observe the effect of Xiaoqinglong decoction on endothelial-mesenchymal transition(EMT)in human pulmonary arterial endothelial cell(HPAEC)and the involvement of the Toll-like receptor/nuclear factor-κB/hypoxia-inducible factor-1α(TLR/NF-κB/HIF-1α)pathway in this mechanism.Methods Thirty-six male Sprague Dawley(SD)rats and HPAEC were randomly divided into control group,model group,Xiaoqinglong decoction plus Earthworm group,Bosentan tablet group,dimethyl sulfoxide(DMSO)group,and monophosphoryl lipid A(MPL)group.PAH rat models and HPAEC models were established by hypoxic exposure.The Xiaoqinglong decoction plus Earthworm group received intragastric administration Xiaoqinglong decoction plus Earthworm(5 g·kg-1·d-1)or cultured with 10%corresponding drug serum,the Bosentan group received Bosentan(100 mg·kg-1·d-1)by gavage or cultured with 10%corresponding drug serum,the MPL group received 1 μg MPL,and the DMSO group received an equivalent volume of the DMSO and corn oil mixed solvent as a negative control for the MPL group.The hemodynamic parameters,including mean pulmonary arterial pressure(mPAP),right ventricular systolic pressure(RVSP),and the maximum rate of right ventricular pressure(+dp/dt max),were measured via right heart catheterization.After euthanasia,lung and heart tissues were collected to assess the right ventricular hypertrophy index(RVHI);hematoxylin-eosin(HE)staining was used to observe the degree of right ventricular cardiomyocyte hypertrophy and to calculate the average intima-media thickness(IMT)in small pulmonary arteries;Western blotting was used to detect the protein expression levels of proliferating cell nuclear antigen(PCNA),CD68,TLR4,NF-κB,HIF-1α,vascular endothelial cadherin,and vimentin;cell counting kit-8(CCK-8),Transwell,and scratch assays were used to observe cell proliferation and migration;Enzyme-linked immunosorbent assay(ELISA)was used to measure the levels of interleukins(IL-8,IL-6),tumor necrosis factor-α(TNF-α),endothelin-1(ET-1),and nitric oxide(NO).Results Compared with the model group,the Xiaoqinglong decoction plus Earthworm group showed significant reductions in mPAP,RVSP,RVHI,and IMT in PAH rats[mPAP(mmHg,1 mmHg≈0.133 kPa):22.17±1.94 vs.42.00±4.90,RVSP(mmHg):34.67±3.20 vs.52.83±3.76,RVHI:0.402±0.057 vs.0.822±0.101,IMT:(37.85±2.49)%vs.(62.06±4.52)%,all P<0.05],and a significant increase in+dP/dT max(mmHg/s:2 730.83±137.89 vs.1 718.33±148.36,P<0.05).Western blotting and ELISA results showed that compared with the model group,the Xiaoqinglong decoction plus Earthworm group had significantly lower protein expression of PCNA and CD68 in lung tissue,and levels of inflammatory factors(IL-6,IL-8,TNF-α)in rat serum[lung tissue:PCNA protein expression(PCNA/GAPDH)was 1.56±0.08 vs.2.20±0.26,CD68 protein expression(CD68/GAPDH):1.46±0.09 vs.2.60±0.23;serum:IL-8(ng/L)was 39.67±6.28 vs.149.17±7.49,IL-6(ng/L):81.00±6.63 vs.211.00±25.31,TNF-α(ng/L):213.17±24.86 vs.799.50±43.51,all P<0.05].In vitro experiments,compared with the model group,Xiaoqinglong decoction plus Earthworm inhibited abnormal proliferation(A value:2.052±0.087 vs.2.242±0.057,P<0.05)and migration[number of migrating cells(per field):101.33±12.01 vs.226.67±17.56,P<0.05]of HPAEC,and reversed the EMT process,manifested as upregulation of vascular endothelial cadherin protein expression levels(vascular endothelial cadherin/GAPDH:0.39±0.06 vs.0.12±0.03,P<0.05)and downregulation of vimentin protein expression(vimentin/GAPDH:4.96±0.33 vs.7.89±0.44,P<0.05).Western blotting results indicated that compared with the model group,the protein expression levels of TLR4,the ratio of phosphorylated p65 to total p65,and HIF-1α in both lung tissue and HPAEC were significantly reduced in the Xiaoqinglong decoction plus Earthworm group[lung tissue:TLR4 protein expression(TLR4/GAPDH)was 3.13±0.20 vs.4.38±0.30,p-p65/p65 ratio:7.11±0.81 vs.12.73±1.80,HIF-1α protein expression(HIF-1α/GAPDH):2.37±0.32 vs.4.45±0.34;HPAEC:TLR4 protein expression(TLR4/GAPDH)was 1.42±0.03 vs.2.43±0.05,p-p65/p65 ratio:6.01±1.84 vs.11.28±1.06,HIF-1α protein expression(HIF-1α/GAPDH)was 3.24±0.17 vs.5.50±0.44,all P<0.05],accompanied by upregulated vascular endothelial cadherin protein expression(vascular endothelial cadherin/GAPDH:0.66±0.03 vs.0.49±0.03,P<0.05)and downregulated vimentin protein expression(vimentin/GAPDH:1.81±0.12 vs.2.47±0.10,P<0.05),indicating that Xiaoqinglong decoction plus Earthworm inhibits the EMT process in endothelial cells by suppressing the activation of the TLR/NF-κB/HIF-1α pathway.Experiments with a TLR agonist further confirmed that activation of the TLR pathway reverses the protective effects of Xiaoqinglong decoction plus Earthworm,as shown by the MPL group compared to the DMSO group having significantly increased protein expression of the p-p65/p65 ratio and HIF-1α[p-p65/p65 ratio:2.17±0.35 vs.1.08±0.14,HIF-1α/GAPDH:3.96±0.25 vs.1.03±0.10,both P<0.05],further decreased vascular endothelial cadherin protein expression(vascular endothelial cadherin/GAPDH:0.66±0.04 vs.0.99±0.02,P<0.05),further increased vimentin protein expression(vimentin/GAPDH:1.53±0.12 vs.0.93±0.07,P<0.05),along with enhanced cell migration capacity[number of migrating cells(per field):176.67±17.50 vs.107.00±11.14;cell migration rate in scratch assay:(34.32±2.82)%vs.(22.71±2.49)%,both P<0.05]and increased proliferation activity(48 hours A value:2.156±0.044 vs.1.810±0.088,P<0.05).Conclusions Xiaoqinglong decoction combined with Pheretima not only significantly reduces pulmonary artery pressure,improves cardiac function and mitigates pulmonary vascular fibrosis in PAH rats,but also alleviates pulmonary vascular remodeling by inhibiting inflammatory responses and EMT.It can further decrease the content of ET-1,increase the level of NO,and ameliorate vascular stenosis.This result further indicates that exterior-relieving medicines exert a significant dilating and supporting effect on the narrowed meridians and collaterals.

OBJECTIVE:In recent years,the number of clinical research reports on acupuncture and manipulation for the treatment of greater occipital neuralgia has gradually increased,but the quality is uneven.There is currently no literature evaluating the quality of published reports,which is not conducive to the promotion of clinical use of these therapies.Therefore,this article assessed the reporting quality of randomized controlled trials on acupuncture and manipulation for greater occipital neuralgia.METHODS:Cochrane Library,PubMed,Web of Science,Embase,China National Knowledge Infrastructure(CNKI),VIP,WanFang Data,and Chinese BioMedical Literature Database(CBM)from inception to May 20,2024 were searched.The reporting quality of included randomized controlled trials was independently evaluated by two investigators using the CONSORT statement,STRICTA checklist,and Cochrane bias of risk assessment tool.A third investigator resolved any disagreement.RESULTS:A total of 62 articles were included.Based on the CONSORT statement,59.46％(22/37)of all entries had a reporting rate of less than 50％,mainly including"Identification as a randomized trial in the title(1/62,1.61％),""How sample size was determined(7/62,11.29％),""Implementation(1/62,1.61％),""Blinding(1/62,1.61％),"and"Reports of Funding(4/62,6.45％)."According to the STRICTA checklist,29.41％(5/17)of all entries had a reporting rate of less than 50％,mainly including"Details of other interventions(7/58,12.07％),""Setting and context of treatment(0/58,0％),"and"Description of participating acupuncturists(0/58,0％)."CONCLUSION:The reporting quality of randomized controlled trials on acupuncture and manipulation therapy for greater occipital neuralgia remains low.Future researchers need to make greater efforts to strictly adhere to the CONSORT statement and STRICTA checklist during trial design,implementation,and reporting.This will facilitate the standardization of research in this field and enhance the reliability and reproducibility of the research results.

Objective The kinetic parameters of Lin's squeezing-pressing adjustment manipulation were collected for the analysis of its mechanical characteristics,thus to establish a standardized operating procedure to guide clinical teaching of this technique.Methods Ten healthy male trainees(aged 20-30 years)from the Tuina Department of Guangdong Provincial of Chinese Medicine were selected as the subjects.A multi-point thin-film pressure testing system was used to collect mechanical parameters during the operation of Lin's squeezing-pressing adjustment manipulation.The mechanical characteristics were analyzed,and then a mathematical model of time-mechanics curve was constructed.Results(1)The kinetic parameters of Lin's squeezing-pressing adjustment manipulation were as follows:preload force averaged(279.45±19.36)N with a duration of(0.98±0.03)s,the valley value of preload force averaged(137.45±3.59)N,the maximum impact force was(495.56±7.33)N,the impact duration averaged(0.15±0.01)s,the impact velocity averaged(3 183.96±94.76)N/s,and the impulse was(57.16±1.82)N/s.(2)The fitting function of impact force showed large absolute values for both ascending and descending slopes,and the ascending slope was significantly greater than the descending slope,indicating that the Lin's manipulation stressed on rapid outburst of the strength and withdrawal of the strength.(3)One-way ANOVA revealed no statistically significant differences in the preload force and its duration and valley value,the maximum impact force,and impact time among different operators(P＞0.05).Conclusion The analysis of kinetic parameters demonstrates that skilled operators maintain relatively stable mechanical parameters when performing Lin's squeezing-pressing adjustment manipulation.This study provides a preliminary digital analysis of the mechanical characteristics of Lin's bone-setting manipulation in addressing"bone misalignment and tendon displacement",which supplies objective evaluation criteria for the technique.

Objective To observe the clinical efficacy of thumb-tack needling therapy combined with Oxycodone Hydrochloride Sustained-Release Tablets in treating patients with severe cancer pain caused by malignant tumors.Methods A total of 60 patients diagnosed with severe cancer pain who were admitted to the Traditional Chinese Medicine Department of Qingpu Branch,Zhongshan Hospital Affiliated to Fudan University between November 2023 and December 2024 were selected as study subjects.Patients were randomly divided into an observation group and a control group using a random number table,with 30 cases in each group.The control group received conventional western medicine pain management,while the observation group received additional thumb-tack needling therapy based on the control group's treatment.The treatment duration was 2 weeks.After treatment,clinical efficacy was evaluated by observing changes in European Quality of Life-5 Dimensions(EQ-5D)scores,Numerical Rating Scale(NRS)scores,Cancer Pain Self-Efficacy Scale(CPSS)scores,and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire(EORTC QLQ-C30)scores in both groups before and after treatment.Changes in serum levels of prostaglandin E2,endothelin-1,β-endorphin,and substance P were also compared.Safety and adverse reactions were assessed.Results(1)The total analgesic effective rate was 76.67％(23/30)in the observation group and 46.67％(14/30)in the control group.The total effective rate in the observation group was significantly higher than that in the control group,with a statistically significant difference(P＜0.05).(2)After treatment,serum levels of prostaglandin E2,endothelin-1,β-endorphin,and substance P were significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(3)After treatment,EQ-5D scores,NRS scores,and CPSS scores were significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(4)After treatment,EORTC QLQ-C30 scores were significantly improved in both groups(P＜0.05),and the improvement in the observation group was significantly greater than that in the control group,with a statistically significant difference(P＜0.05).(5)The incidence of adverse reactions was 53.33％(16/30)in the observation group and 83.33％(25/30)in the control group.The incidence of adverse reactions in the observation group was significantly lower than that in the control group,with a statistically significant difference(P＜0.05).Conclusion Thumb-tack needling therapy combined with Oxycodone Hydrochloride Sustained-Release Tablets significantly alleviates pain symptoms,improves health status and self-efficacy,and enhances the quality of life in patients with severe cancer pain caused by malignant tumors.

Objective:To develop a quality assessment index system for infection prevention and control in integrated medical and elderly care facilities, providing methods for assessing infection control quality and a theoretical basis for enhancing infection prevention and control capabilities.Methods:This study initially constructed a framework for the quality evaluation index system through literature reviews, work specifications and standards and expert interviews. The Delphi method was employed to conduct two rounds of consultations with 19 experts to evaluate the necessity, feasibility, stability, and sensitivity of the indicators. The expert′s active coefficient, authority coefficient, degree of consensus, and coordination were statistically analyzed. The indicators were revised based on expert opinions to finalize the evaluation index system. The weights of the evaluation dimensions were determined using the Analytic Hierarchy Process (AHP), while the weights of the indicators were determined using the proportional allocation method. Reliability was assessed via Cronbach′s α coefficient, and content validity was verified through the Content Validity Index ( CVI). Results:After two rounds of expert consultation, the expert positive coefficient, expert authority coefficient ( Cr) and expert coordination coefficient Kendall′s W was 100%, 0.992 and 0.634 ( P<0.001), indicating high expert authority, good concentration and coordination of opinions. The assessment index system for infection prevention and control quality in integrated medical and elderly care facilities was ultimately constructed, comprising three primary indicators, 18 secondary indicators and 68 tertiary indicators. Among the primary indicators, the process quality had the highest weight of 0.338. Within the process quality, the secondary indicators with the highest weights were infection control material allocation, hand hygiene quality and the management of cluster outbreaks. A total of 11 unique evaluation indicators for integrated medical and elderly care facilities were established, with the highest weighted indicator being the rate of standardized surveillance of infection-related risk factors. Reliability and validity analyses demonstrated that the overall Cronbach′s α coefficient of the system was 0.991, and the Scale-level Content Validity Index was 0.936, confirming good reliability and validity. Conclusion:The evaluation index system constructed in this study can serve as an effective assessment tool for the quantitative evaluation of infection control quality in integrated medical and elderly care facilities. Furthermore, it is recommended that the system undergo continuous optimization concerning its application.

In recent years,as the survival time of liver transplant recipients continues to increase,serious complications after transplantation,including diabetes,which affects the long-term survival of patients,have attracted more and more attention.Diabetes after liver transplantation can increase the risk of infection and cardiovascular disease,which in turn affects the survival rate of grafts and patients,and therefore,identification and intervention for high-risk populations are of great importance for improving the prognosis of patients.This article reviews the risk factors for diabetes after liver transplantation,in order to deepen the understanding of diabetes after liver transplantation and provide a theoretical basis for disease prevention and treatment.

Objective To evaluate the effect of different doses of esketamine combined with propofol medium and long chain fat emulsion in painless gastroenteroscopy.Methods 144 patients who were scheduled to receive painless gastroenteroscopy from January 2022 to December 2023 were randomly divided into four groups with 36 cases in each group.The load dose of esketamine in group A,group B and group C was 0.2,0.3 and 0.4 mg/kg respectively,and group D was treated with equivalent normal saline instead of esketamine as the control.All the patients were administrated with propofol medium and long chain fat emulsion during the examination.Heart rate(HR),mean arterial pressure(MAP)and percutaneous arterial oxygen saturation(SpO2)were recorded immediately after electrocardiograph monitoring was established(T0),immediately before examination(T1),immediately after gastroscopy placement(T2),immediately before colonoscopy(T3),immediately after colonoscopy implantation(T4)and immediately after examination(T5).The dosage of propofol medium and long chain fat emulsion,recovery time and discharge time were compared among the four groups.Patients were assessed with quality of recovery-40 questionnaire(QoR-40)at T0 and at wake time(T6).The adverse reactions of the four groups were compared.Results There were statistically significant differences in the temporal effects of HR,MAP and SpO2 among the 4 groups(F=3.91,21.65,6.17,P＜0.05);There were statistically significant differences in the intergroup effects of HR,MAP and SpO2 among the 4 groups(F=14.57,7.14,30.34,P＜0.05).The variation trend of SpO2 in groups A,B,C and D was statistically significant(F=2.88,P＜0.05).The first and total dosage of propofol medium and long chain fat emulsion,and the recovery time of the four groups were statistically significant(P＜0.05).The initial dosage and total dosage of propofol medium and long chain fat emulsion in group A,group B and group C were significantly lower than those in group D(P＜0.05),and group B and group C were significantly lower than group A(P＜0.05),but there was no significant difference between group B and group C(P＞0.05).The recovery time of group A and group B were significantly shorter than that of group C and group D(P＜0.05),and group C was significantly longer than that of group D(P＜0.05),and there was no significant difference between group A and group B(P＞0.05).There was no significant difference in the time of get discharged from the hospital among the four groups(P＞0.05).The total scores of QoR-40 in four group at T6 were significantly lower than those at T0 respectively(P＜0.05).T6 QoR-40 total score:group B was significantly higher than group A,Group C and group D(P＜0.05),group A and group C were significantly higher than group D(P＜0.05),and there was no significant difference between group A and group C(P＞0.05).There were significant differences in the incidence of hypoxemia,hypotension,bradycardia,tachycardia,body movement and dizziness among the four groups(P＜0.05).The incidence of hypoxemia,hypotension and bradycardia in group B and group C was significantly lower than that in group D(P＜0.083),and the incidence of dizziness in group C was significantly higher than that in group D(P＜0.0083).Among them,1 case in group A and 3 cases in group D needed mask pressure ventilation due to hypoxemia.There was no significant difference in the incidence of nausea and vomiting among the four groups(P＞0.05).Conclusion During painless gastroenteroscopy,the application of 0.3 mg/kg esketamine combined with propofol medium and long chain fat emulsion can help maintain the hemodynamic stability,alleviate the respiratory and circulatory inhibition caused by propofol medium and long chain fat emulsion,accelerate recovery,and reduce adverse reactions in patients.

Objective This study aims to investigate and analyze the effects of the incentive-coordination-supervision mechanism applied to training management of medical staff under the modern hospital management system.Methods A total of 84 medical staff members working at the hospital from February 2022 to February 2024 were selected for the study.They were di-vided into a reference group(n=42,February 2022 to February 2023)and a study group(n=42,March 2023 to February 2024)based on the time period.The reference group underwent routine management,while the study group underwent manage-ment based on the incentive-coordination-supervision mechanism.The quality of management,occurrence of adverse events,management satisfaction,and core competencies were compared between the two groups.Results The study group had higher scores in cultural construction,reward and punishment mechanism,reporting system,and communication and coordination mech-anism than the reference group(all P＜0.05).The occurrence rate of adverse events was lower in the study group than in the reference group(7.14％vs 23.81％)(P＜0.05).The study group had higher satisfaction rates in management methods,man-agement content,management forms,and communication skills(95.24％,92.86％,97.62％,and 95.24％,respectively)compared to the reference group(78.57％,73.81％,76.19％,and 73.81％,respectively)(all P＜0.05).The study group had higher scores in all core competencies compared to the reference group(all P＜0.05).Conclusion The application of the incentive-coordination-supervision mechanism in training management of medical staff shows favorable effects,improving the qual-ity of management,management satisfaction,and core competencies,and reducing the occurrence of adverse events.

Objective:The aim of this study was to explore the risk factors that affect implementation of the innovative technique of single-incision laparoscopic appendectomy (solo-SLA) without assistance in patients with complicated appendicitis, the goal being improving surgical success rates and reducing the incidence of complications.Methods:This was an observational study. Indications for solo-SLA surgery were as follows: (1) computed tomography or ultrasound findings suggestive of acute appendicitis, accompanied by a high white blood cell count and C-reactive protein concentration; (2) disease course exceeding 72 hours, standard anti-infection treatment ineffective, inflammatory reaction not localized, surgery mainly aimed at abscess drainage, and the appendix removed if indicated intraoperatively; (3) acute onset stabilized for more than 3 months after conservative treatment; and (4) recurrent chronic appendicitis. Relative contraindications comprised: (1) cardiopulmonary insufficiency, extremely high risk for general anesthesia for laparoscopic surgery; (2) severe coagulation dysfunction; and (3) imaging findings suggestive of formation of a peri-appendiceal abscess, stable after anti-infection treatment, and a tendency for the inflammatory reaction to localize. We retrospectively collected clinical data of 106 patients with complicated appendicitis who had undergone solo-SLA in the Department of Emergency Surgery, Peking University People's Hospital from February to October 2023. Preoperative computed tomography showed appendiceal fecaliths, blurring of the tissue surrounding fat, intra- and extra-luminal gas and exudate, peri-appendiceal abscess, ascites, and intestinal obstruction by appendicitis. The study cohort comprised 53 male and 53 female patients aged (41.4±17.4) years. The median body mass index was (24.2±3.6) kg/m 2 and median preoperative body temperature (37.3±0.9)℃ Appendicitis had been present for >3 days in 21 of the patients (19.8%) and the maximum diameter of the appendix was (12.4±3.8) mm. The efficacy of the surgery was assessed and logistic regression analysis used to explore the factors affecting the duration of the procedure. The relationship between the maximum diameter of the appendix and duration of surgery was non-linear and was explored using a logistic regression model with restricted cubic spline (RCS). Results:Only one patient required conversion to open surgery; all the other patients successfully completed solo-SLA with a median intraoperative blood loss of 10 (1-100) ml and a surgical time of (65.4±31.7) minutes. Pain scores on postoperative Day 1 and 7 were (3.4±3.2) points and (1.5±1.7) points, respectively. There were no significant postoperative complications .The postoperative hospital stay was (3.5±1.5) days and the interval to resuming normal activities 14 (2-40) days. According to univariate and multivariate analyses, disease course >3 days (OR=5.19, 95%CI: 1.59-16.98, P=0.006) and C-reactive protein >10 mg/L (OR=1.01,95%CI: 1.00-1.02, P=0.003) were independent risk factors for surgical duration >60 minutes, whereas the maximum diameter of the appendix was not independently associated with duration of surgery (OR=1.10, 95%CI: 0.97-1.25, P=0.119). RCS analysis results showed a "U-shaped" association between the maximum diameter of the appendix and duration of surgery, the inflection point of the RCS curve being at a diameter of 10 mm. When the maximum diameter of the appendix was <10 mm, increases in diameter were not associated with longer duration of surgery (OR=1.15,95%CI: 0.55-2.58, P=0.710); whereas when the diameter was ≥10 mm, the maximum diameter of the appendix was associated with increased duration of surgery (OR=1.20, 95% CI: 1.04-1.42, P=0.022). Conclusion:The solo-SLA procedure can be performed to treat complicated appendicitis. A disease course >3 days, C-reactive protein concentration >10 mg/L, and maximum diameter of the appendix ≥10 mm are all associated with greater difficulty of solo-SLA surgery.

Objective To investigate the influencing factors of the course of perioperative prophylactic antibiotics in patients undergoing total hip arthroplasty,and explore management strategies for enhancing perioperative prophylactic medication administration.Methods The clinical data for patients undergoing total hip arthroplasty at Affiliated Hospital of Chengdu University from January,2020 to September,2024 were retrospectively collected.Patients were divided into a 24 h group and a 48-72 h group based on the duration of prophylactic antibacterial therapy.The general characteristics,surgical-related indicators,preoperative and postoperative laboratory test results,and surgical outcome measures between the two groups of patients were compared.Multivariate Logistic regression analysis was performed to identify influencing factors associated with prolonged duration of prophylactic antibacterial therapy.Results A total of 126 patients who underwent total hip arthroplasty were enrolled,including 74 cases in the 24 h group and 52 cases in the 48-72 h group.Univariate analysis results showed that there were statistically significant differences in the following indicators between the two groups:surgical cause,surgical duration,intraoperative blood loss,drainage duration of plasma drainage tubes,preoperative white blood cell count,and preoperative neutrophil count(P<0.05).The results of multivariate Logistic regression analysis showed that the reason for surgery and the duration of plasma drain tube drainage were the influencing factors of antimicrobial treatment course for total hip arthroplasty(P<0.05).The results of receiver operating characteristic curve analysis showed that the prediction model(constructed based on the drainage time of plasma drainage tube)for prophylactic antimicrobial treatment course to 48-72 h was 0.721.When the drainage time of plasma drainage tubes was≥40.56 h,the risk of requiring prophylactic antimicrobial therapy for an extended course of 48-72 h increased significantly.Conclusion The patient's surgical reason and the duration of plasma drain drainage may be related to the prophylactic antimicrobial course of more than 24 hours.Clinical pharmacists may utilize this parameter as a patient-specific characteristic,with the support of information systems,the hierarchical patient management can be implemented,thereby enhancing the effectiveness of medication surveillance and progressively elevating the 24 h discontinuation rate of perioperative prophylactic antibiotics.
