Objective:To investigate the application effect of medical failure modes and effects analysis(FMEA)in reducing the inci-dence rate of catheter dislodgement in patients in the post-anesthesia care unit(PACU).Methods:A retrospective study was con-ducted among 469 PACU patients in our hospital from January 2023 to June 2024.According to the application time of FMEA,the pa-tients were divided into routine group(234 PACU patients who did not receive FMEA from January to June 2023)and FMEA group(235 PACU patients who received FMEA from July 2023 to June 2024).The two groups were compared in terms of the incidence rate of catheter dislodgement,risk priority number(RPN)coefficients(including professional knowledge,risk awareness,and intervention guidance),the quality of recovery of consciousness(including the time to complete recovery of consciousness and the length of stay in the PACU),and the degree of satisfaction with nursing(including risk management,nursing services,and nursing techniques).Results:The FMEA group had a significantly lower incidence rate of catheter dislodgement than the routine group[0.43%(1/235)vs.2.99%(7/234),the difference was statistically significant(χ2=4.604,P=0.032)].Compared with the routine group,the FMEA group had significantly lower RPN coefficients of risk awareness t=52.518,professional knowledge t=49.641,and intervention guidancet=61.592(P<0.001).Compared with the routine group,the FMEA group had significantly shorter time to complete recovery t=18.087 of consciousness and length of stay in the PACUt=15.710(P<0.001).The FMEA group had a significantly higher degree of satisfaction with nursing than the routine group in terms of risk management t=19.794,nursing services t=10.825,and nursing techniques t=14.555(P<0.001).Conclusion:The application of FMEA manage-ment in PACU patients can reduce the incidence rates of catheter dislodgement and risk events and improve the quality of recovery of consciousness and the degree of satisfaction with nursing,and there-fore,it has important clinical significance.

Objective:To explore the value of applying stone burden in evaluating the treatment efficacy of patients with upper ureteral stones undergoing extracorporeal shock wave lithotripsy.Methods:A retrospective selection was conducted on 328 patients with upper ureteral stones admitted to Beijing Friendship Hospital, Capital Medical University from October 2018 to August 2024. The maximum diameter of the stones was 1.0-2.0 cm, and the patients were divided into successful lithotripsy group ( n=306) and failed lithotripsy group ( n=22) based on the success or failure of lithotripsy. Using multi-slice spiral CT scanning to collect the longest diameter, maximum CT value, volume, and average CT value of the stones in the enrolled patients, evaluate the predictive value of stone burden on the effectiveness of extracorporeal shock wave lithotripsy in patients with upper ureteral stones. Measurement data were expressed as mean ± standard deviation ( ± s), and t-test was used for comparison between groups; count data were expressed as the cases and percentage, and Chi-square test was used for comparison between groups. Univariate and multivariate Logistic regression analysis were used to evaluate the factors affecting the efficacy of extracorporeal shock wave lithotripsy in patients with upper ureteral stones. The area under the curve (AUC) of receiver operating characteristic (ROC) curve was used to evaluate the predictive value of each influencing factor for the therapeutic effect. Results:The results of univariate analysis showed that there were no statistically significant differences in age, gender, disease duration, and stone side between the successful and failed lithotripsy groups ( P>0.05). However, there were statistically significant differences in the longest diameter, maximum CT value, volume, average CT value of the stones and stone burden ( P<0.05). The results of multivariate Logistic regression analysis showed that the longest diameter, maximum CT value, volume, average CT value of the stones and the stone burden were all risk factors affecting the therapeutic effect of extracorporeal shock wave lithotripsy for upper ureteral stones ( P<0.05). The results of ROC curve analysis showed that the AUC of the longest diameter, maximum CT value, volume, average CT value of the stones and the stone burden, burden 1, burden 2, and burden 3 were 0.844, 0.827, 0.948, 0.873, 0.889, 0.835, 0.911 and 0.865, respectively. Conclusion:The stone burden has good predictive value for the therapeutic effect of extracorporeal shock wave lithotripsy in the treatment of upper ureteral stones, and is worthy of promotion and application.

Objective To observe the effects of Levo-tetrahydropalmatine(l-THP)on the expression,regression and relapse of conditioned place preference(CPP)in ketamine induced rats,and to detect the content of dopamine(DA)in the striatum(caudate putamen,CPu)of the rat brain at different time points.Methods Ketamine addiction rat model was established by CPP.The effects of l-THP on the expression,regression and relapse of ketamine induced rat CPP were investigated using CPP score as the index.The content of DA in CPu of rats was determined by ultra-performance liquid chromatography coupled to tandem mass spectrometry(UPLC-MS/MS)after ketamine administration and l-THP intervention at 30 min,60 min,90 min,120 min and 150 min.Results It indicated that 1-THP could decrease the expression of CPP in ketamine induced rats,promote the process of CPP resolution and inhibit the process of relapse.In addition,l-THP combined with ketamine administration significantly inhibited the ketamine-induced increase in DA content in the CPu of the rats.Conclusion The mechanism of l-THP inhibiting the reward effect of ketamine may be related to blocking DA receptors and reducing the release of DA neurotransmitters.l-THP has potential implications for the treatment of ketamine addiction.

OBJECTIVE To investigate the implementation effects of the national centralized drug volume-based procurement policy （abbreviated as “national centralized procurement policy”） in Guangxi Zhuang Autonomous Region prefecture， and to provide a reference for the future centralized drug procurement work of the medical institution. METHODS Drug procurement data before and after policy implementation were included in the study. The six secondary indicators （such as availability， affordability， and drug safety） and eighteen third-level indicators （such as completion rate of agreed purchase volume， affordability level， drug revenue proportion） were introduced， guided by the policy objectives and issues of concern to policy beneficiaries. Descriptive statistics was adopted to analyze the data before and after policy implementation （in 2019 and 2020） in terms of differences and change trends. RESULTS In terms of accessibility， the participation rate of medical institutions in Guangxi Zhuang Autonomous Region was 92.55%， the proportion of diseases involved and median completed procurement rate were 40.16%， and 287.82% respectively， and the total centralized delivery rate was 97.20%. In terms of affordability， the total reduction amplitude in drug price was 74.80% from 2019 to 2022； the charge for medicine per capita in hospitalization， the proportion of medicine used for outpatient service and hospitalization， decreased by 17.61%， 10.22%， and 20.10% in order； the burden levels on medical fares for patients were all below 1 in addition to chronic diseases， and anti-tumor drugs. In terms of the impact on medicine， the ratio of adverse drug reaction event cases in 2022 was 66.00%， an increase of 1.29% compared to the previous； since the implementation of the policy， 12 drugs from local pharmaceutical enterprises from Guangxi Zhuang Autonomous Region had passed the consistency evaluation， and the market concentration rate of the top 8 pharmaceutical companies was less than 20.00%. In terms of the impact on healthcare and medical insurance， the public medical institutions achieved generic substitution for originator drugs mostly until 2022； about 9.12% of drugs that were non- centrally purchased in the same category were used； 63.39% of people under investigation did not show a need for a second dressing change； drug expenditure decreased by 2.459 billion yuan. CONCLUSIONS The national centralized procurement policy achieves a significant effect in Guangxi Zhuang Autonomous Region. On the other hand， attention should be paid to these suggestions as follows: expanding the category of drugs used in clinic， conducting clinically comprehensive evaluation of selected drugs， and improving reasonable allocation strategy， etc.

【Objective】 To investigate the factors affecting the length of hospitalization after the Sun's procedure in patients with type A aortic coarctation. 【Methods】 From January 2018 to June 2023, the clinical data, related laboratory indicators and perioperative blood transfusion data of patients with type A aortic dissection who underwent Sun's procedure in the First Hospital of Lanzhou University were collected. LASSO regression was used to screen the characteristics related to the length of hospital stay, and linear regression analysis was used to determine the risk factors for prolonged length of hospital stay. 【Results】 The statistical analysis of 242 patients showed that the amount of red blood cell transfusion, plasma transfusion, platelet transfusion and autologous blood transfusion were the influencing factors of the length of hospital stay in patients with type A aortic dissection after operation. The total sum of squared deviations of the linear regression equation fitting the total length of hospital stay was statistically significant (F= 10.504, P<0.001). 【Conclusion】 Perioperative red blood cell transfusion,plasma transfusion,platelet transfusion and autologous blood transfusion are risk factors for prolonged postoperative hospitalization in patients undergoing the Sun's procedure for type A aortic coarctation. Control of operation time and reduction of intraoperative blood loss may help to prevent prolonged postoperative hospital stay and other adverse conditions.

Purpose: Through meta-analysis, we aimed to assess the efficacy and safety of drug-coated balloons (DCB), compared with drugeluting stents (DES) or uncoated devices, in the treatment of de novo coronary lesions. Materials and Methods: Only randomized controlled trials were included. The primary outcomes were late lumen loss (LLL), target lesion revascularization (TLR), and major adverse cardiac events (MACEs). Subgroup analyses were conducted based on clinical indications, whether DCBs were used with a systematic or bailout stent, and types of DESs. Results: The present meta-analysis demonstrated that DCBs elicit significantly lower incidences of TLR, MACE, and LLL, compared with uncoated devices, and similar incidences, compared with DESs, in the treatment of de novo coronary lesions. Subgroup analysis indicated that DCBs used with a bailout stent achieved lower incidences of binary restenosis and myocardial infarction, compared with uncoated devices, and provided less LLL than DESs. DCBs showed similar rates of TLR and MACE, with significantly less LLL, than DESs in treating de novo small-vessel diseases. The clinical efficacy of DCBs was similar to that of secondgeneration DES. Conclusion Overall, DCB is favored over bare metal stent alone in treating de novo coronary lesions. DCBs appear to be a promising alternative to DESs in the treatment of de novo coronary lesions.

Objective:To investigate the safety and efficacy of Belintoumab on the treatment of children with acute B-lymphoblastic leukemia (B-ALL).Methods:The clinical data of 10 children with CD 19+ B-ALL who were admitted to the Department of Pediatrics, the First Affiliated Hospital of Zhengzhou University from September 2021 to May 2022 and treated with Belintoumab were analyzed retrospectively. Results:Among the 10 cases, there were 6 recurrent cases, 3 cases with persistent minimal residual disease (MRD) positive after an initial treatment, and 1 case complicated with invasive candidiasis.Before treatment, bone marrow blasts ≥0.25, and that ranged 0.05-<0.25 were detected in 2 cases and 1 case, respectively.Seven cases had a complete remission (CR) of bone marrow, 6 of which were MRD positive and 1 case was MRD negative.After treatment with Belintoumab, the CR rate was 66.7% (2/3). The overall MRD negative rate was 88.9% (8/9), and the negative rate in previously MRD positive children was 100% (6/6). The median follow-up time was 4.1 (1.6-10.0) months after the application of Belintoumab.The overall survival (OS) rate was 70.0% (7/10). Eight MRD negative children received hematopoietic stem cell transplantation, and the OS rate was 75% (6/8). Survived children did not relapse until the last follow-up visit.Fever (90%, 9/10) was the most common adverse events, followed by neutropenia (90%, 9/10). One case (10%, 1/10) of neurotoxicity was seizures (grade 2) and one case (10%, 1/10) suffered cytokine release syndrome (grade 2), which did not influence the therapeutic efficacy of Belintoumab after symptomatic treatment.Conclusions:Belintoumab is safe and effective on the treatment of children with recurrent/refractory CD 19+ B-ALL, and those with MRD positive who have achieved CR in bone marrow have a higher rate of turning negative.Belintoumab can also be used as a bridge scheme for CD 19+ B-ALL children who cannot tolerate chemotherapy.

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.
