OBJECTIVE To construct a whole-process management system for the smart pharmacy based on the integration of drug batch numbers and traceability codes， aiming to solve the problems of low upload rates and traceability difficulties of drug traceability codes in the central pharmacy， and to enhance its level of refined management and medication safety. METHODS Following the FOCUS-PDCA framework（find，organize，clarify，understand，select-plan，do，check，act）， a drug batch number and traceability code management system was established by optimizing batch number management processes， introducing “pre-scan registration” technology， and establishing a dynamic “code pool” mechanism. Based on medical insurance upload data and operational performance indicators in our hospital from June to August 2025， the differences in management efficacy before and after the implementation of the system were compared and analyzed. RESULTS The drug batch number and traceability code management system was successfully established， achieving “one-object， one-code” whole-process association with batch numbers for inpatient drugs， especially split drugs. After the application of this system， the upload rate of inpatient drug traceability codes reached 100%， significantly higher than the average upload rate of inpatient drugs in other tertiary hospitals in our city （with the highest rate being only 23.22%， P ＜0.001）. The inventory stocktaking error rate dropped from 0.9% to 0.3% （a decrease of 66.7%）； the number of daily dispensing errors decreased from 1.43 to 0.37； the dispensing time （14.75 min） for temporary medical orders recovered to the routine level （14.42 min） prior to the system implementation. CONCLUSIONS By adopting the “pre-scan registration-code pool management-closed-loop traceability” model， this system enables traceability for individual drug products in their smallest packaging units， improves the upload rate of traceability codes， significantly reduces the medication dispensing error rate， and does not increase the time cost for temporary medical order dispensing， thereby balancing efficiency with closed-loop traceability.

BACKGROUND:Allogeneic tendons are often used in clinical treatment of tendon and ligament injuries,which need to be treated before clinical application.At present,allogeneic tendons will face multiple freeze-thaw cycles after cryopreservation,but there is no relevant research on the changes in the properties of the treated allogeneic tendon after several freeze-thaw cycles.OBJECTIVE:To explore the changes in mechanical properties and composition of allogeneic tendon after multiple freeze-thaw cycles.METHODS:The treated allogeneic tendon was frozen and thawed 3,6,and 10 times at-40 ℃(or-80 ℃),respectively.The mechanical test,DNA content,glycosaminoglycan sulfate,hydroxyproline content and total protein content of the allogeneic tendon after freezing and thawing were detected.RESULTS AND CONCLUSION:(1)There was no significant difference in the maximum load,maximum load elongation,tensile strength and elastic modulus between groups after freezing-thawing cycles for 3,6,and 10 times at-40 ℃(P＞0.05).There was no significant difference in the maximum load and maximum load elongation between the groups after freezing-thawing cycles for 3,6,and 10 times at-80 ℃(P＞0.05).The tensile strength of the group with 3 cycles of freezing and thawing was higher than that of the groups with 6 and 10 cycles of freezing and thawing(P＜0.05).The elastic modulus of the group with 3 cycles of freezing and thawing was higher than that of the group with 10 cycles of freezing and thawing(P＜0.05).(2)The freezing and thawing times did not affect the contents of DNA,hydroxyproline,total protein,and sulfated glycosaminoglycan in allogeneic tendon when stored at-40 ℃(or-80 ℃).(3)These findings suggest that in-40℃ storage,the performance of the allogeneic tendon should not be affected by taking out and putting back the tendon less than 10 times,while in-80 ℃ storage,the allogeneic tendon should be taken out and put back less than 6 times.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

Objective To evaluate the reliability and validity of the Chinese version of the Repeatable Battery for the Assessment of Neuropsychological Status(RBANS)in patients with maintenance hemodialysis(MHD).Methods The general information and medical history of 84 MHD patients were collected,and the Mini-Mental State Exam(MMSE),Montreal Cognitive Assessment Scale(MoCA),and RBANS were conducted.The reliability of the scale was assessed by Cronbach α and split-half reliability.The structure and convergent validity of the scale were assessed by confirmatory factor analysis,and the RBANS scores'correlation to MoCA and MMSE scores was analyzed by Spearman correlation analysis.The predictive value of the RBANS total score on cognitive impairment(CI)was analyzed by receiver operating characteristic(ROC)curve.Results The Cronbach's alpha coefficient of the RBANS total scale was 0.896,split-half reliability was 0.911,and reliability for the five dimensions of the RBANS ranged from 0.618 to 0.791.Confirmatory factor analysis indicated that the overall fit of the five-dimensional model of the RBANS scale was acceptable(χ2/df=1.587,root mean square error of approximation=0.084,comparative fit index=0.967,incremental fit index=0.968,Tucker-Lewis index=0.947,goodness of fit index=0.891).The average variance extracted(AVE)for the five dimensions of the RBANS ranged from 0.525 to 0.863,while the composite reliability(CR)ranged from 0.733 to 0.926,indicating good convergent validity of the scale.Furthermore,Spearman correlation analysis revealed that the total RBANS score was negatively correlated to the age of MHD patients and positively correlated to years of education,as well as the total scores of MMSE and MoCA(all P<0.01).The ROC curve analysis indicated that the area under the curve(AUC)for the total RBANS score in predicting CI was 0.891(P<0.01),suggesting a high predictive value.Conclusion The Chinese version of RBANS has good reliability and validity in MHD patients,and can be used as a measure of cognitive function in MHD patients.

Results:①Among the 64 patients with lupus, 19(29.7%) had abnormal radionuclide myocardial imaging, 23 (35.9%) had elevated BNP, and 6 (9.4%) had myocardial involvement on echocardiography. There was no statistical difference between radionuclide myocardial imaging and BNP ( Kappa=0.294, P=0.503), but there was a significant difference between radionuclide myocardial imaging and echocardiography ( Kappa=0.394, P<0.001). ②There was no statistical difference in the EF values measured by resting gated myocardial radionuclide imaging and echocardiography [(64.9±9.6)% vs. (63.2±5.6)%, Z=-1.73, P=0.083]. ③Compared with the normal myocardial group, the myocardial damage group had higher BNP value [(912±1729)pg/ml vs. (297±572)pg/ml, t=-3.05, P=0.002], ESR[(56±42)mm/1 h vs. (34±27)mm/1 h, t=-2.17, P=0.030], and SDI scores[2.16±1.30 vs. 1.04±0.85, t=-3.43, P=0.002], more patients with a course of disease≥10 years [57.9% vs. 28.9%, Z=2.17, P=0.030], and anti-U1RNP antibody[52.6% 24.4%, Z=-2.18, P=0.029] and anti-SSB antibody[31.6% vs. 11.1% Z=-1.97, P=0.049] were statistically different. ④Through binary logistic regression analysis, SDI score [ OR ( 95%CI)=2.444 (1.195, 4.998), P=0.014], anti-U1RNP antibody [ OR ( 95%CI)=4.569 (1.036, 20.150), P=0.045] and disease duration≥10 years [ OR ( 95%CI)=5.218 (1.210, 22.496), P=0.027] were independent risk factors for myocardial damage in SLE patients. Conclusion:Resting gated radionuclide myocardial imaging can accurately provide ventricular motion parameters and can detect myocardial damage in SLE patients at early stage. Disease duration ≥10 years, high SDI score, and positive anti-U1RNP antibodies are independent risk factors for myocardial damage in SLE patients.
