Objective To make rational use of teicoplanin and better management of patients treated with teicoplanin. Methods Nine clinical issues related to the treatment of teicoplanin in Clinical practice guidelines for therapeutic drug monitoring of teicoplanin: a consensus review by the Japanese Society of Chemotherapy and the Japanese Society of Therapeutic Drug Monitoring (Japan, 2022) were interpreted from the perspective of pharmacy. Results The guidelines indicated that the area under drug-time curve/minimum inhibitory concentration was the key pharmacokinetic/pharmacodynamic parameters of teicoplanin.The purpose of therapeutic drug monitoring (TDM) of teicoplanin is to specify the target trough concentration (C_min), which guidelines recommend for severe or complex methicillin-resistant Staphylococcus aureus (MRSA) infection is 20-40 mg/L.The target C_min for uncomplicated MRSA infection with normal or mildly impaired renal function is 15-30 mg/L.For severe and/or complex MRSA infections, such as infective endocarditis and osteomyelitis, the C_min of teicoplanin was 20-40 mg/L. Conclusions The guidelines are aimed at the determination of target C_min of teicoplanin in patients with different pathological conditions, and provide reference for individual drug administration and teicoplanin TDM in clinical treatment.

目的 探讨外周血CD34阳性（CD34⁺）细胞计数对普乐沙福自体干细胞动员效果的预测价值。方法 回顾性分析2021年5月—2023年7月中山大学附属第七医院使用人粒细胞集落刺激因子（G-CSF）联合普乐沙福进行自体干细胞动员的13例患者临床资料,分析普乐沙福动员前后外周血CD34⁺细胞计数的变化及干细胞采集情况。结果 共有13例患者纳入研究,包括淋巴瘤10例和多发性骨髓瘤3例。多发性骨髓瘤患者中1例为新诊断,另2例为复发患者;淋巴瘤患者中3例为套细胞淋巴瘤,6例为弥漫大B细胞淋巴瘤（包括1例复发）,1例为B细胞淋巴瘤（不能明确类型）。本研究纳入的患者均使用G-CSF动员,在使用普乐沙福后CD34⁺细胞计数均升高,使用普乐沙福前中位CD34⁺细胞计数为13.3（2.5~76.1）/μL,使用普乐沙福后中位CD34⁺细胞计数为73.6（10.4~208.70）/μL,升高4.18（1.99~13.60）倍。13例患者中有2例患者在使用普乐沙福前外周血CD34⁺细胞计数<5 /μL,均动员失败。Spearman相关分析结果显示,使用普乐沙福后CD34⁺细胞计数与使用普乐沙福前CD34⁺细胞数呈正相关（r_s=0.769,P=0.003）。多元线性回归分析显示,使用普乐沙福后CD34⁺细胞计数能较好地预测采集结果（P=0.004）。结论 监测外周血CD34⁺细胞计数可预测普乐沙福自体干细胞动员效果,使用普乐沙福后CD34⁺细胞计数越多,CD34⁺细胞采集量越大。

Objective To explore the predictive value of peripheral blood CD34⁺ cell count for the stem cell mobilization effect of plerixafor．Methods The clinical data of 13 patients who used granulocyte colony-stimulating factor + plerixafor for stem cell mobilization in the Seventh Affiliated Hospital of Sun Yat-sen University from May 2021 to July 2023 were retrospectively analyzed．The changes of peripheral blood CD34⁺ cell count in all patients before and after the mobilization of plerixafor were analyzed．Results In 13 enrolled patients,there were 10 lymphoma patients and 3 multiple myeloma（MM）patients．One patient was newly diagnosed with MM,and the other two were recurrent patients．The lymphoma cases included 3 mantle cell lymphoma,6 diffuse large B cell lymphoma and 1 B cell non-Hodgkin's lymphoma（type cannot be specified）．The CD34⁺ cell counts were increased in all patients when mobilized with granulocyte colony-stimulating factor before plerixafor．The CD34⁺ cell count was 13.3（2.5~76.1）/μL and 73.6（10.4~208.70）/μL before and after the use of plerixafor,between which the difference was statistically significant（Z=0.578,P<0.05）,and the median increased of 4.18（1.99~13.6）times．There were 2 patients failed in mobilizing whose CD34⁺ cell count was less than 5 /μL before using plerixafor．Spearman analysis showed that there was a positive correlation in peripheral blood CD34⁺ cell count before and after the use of plerixafor（r_s=0.80,P=0.032）．The CD34⁺ cell count after using plerixafor was a good predictor of the collection results（P=0.002）．Conclusions Monitoring the CD34⁺ cell count in peripheral blood has a certain predictive value for the stem cell mobilization effect of plerixafor．The higher of CD34⁺ cell count after the use of plerixafor,the higher of CD34⁺ collection．

Objective To observe the application of failure mode and effect analysis (FMEA) in monitoring analysis and protection countermeasures of blood-borne occupational exposure of medical personnel. Methods FMEA was used to retrospectively analyze the high risk factors of blood-borne occupational exposure of medical staff in our hospital from January 2018 to June 2019, to calculate the risk priority number (RPN), to give priority to the highest risk factor, to formulate improvement measures. The improved scheme was adopted from July 2019 to December 2020. The RPN value of failure mode, blood-borne occupational exposure and Chinese Hospital Safety Atmosphere Scale (C-HSCS) before and after the implementating of the scheme were compared and analyzed. Results After implementating FMEA, RPN and weight coefficient (W_i) decreased, and the RPN scores were 2 633 and 853 before and after implementation, with a decrease of 67.60%, W_i was 0.729 9 before implementation and 0.268 0 after implementation, with a decrease of 63.28%. Before FMEA, the blood-borne occupational exposure rate was 28.74%, and after FMEA, the rate was 4.65%. After the implementation, the scores of safety work obstruction was (11.99±2.16), cleanliness and tidiness was (11.48±1.89), management and support was (28.58±3.24), conflict and communication was (22.54±2.83), feedback and training was (13.82±2.55), which were higher than those before the implementation: (10.67±2.68), (10.06±2.36), (26.80±3.86), (20.85±2.62), (12.52±1.19), P<0.05. Conclusions Using FMEA in the management of blood-borne occupational exposure of medical personnel could refine high-risk steps, improve the pertinence of improvement measures and reduce occupational exposure.

Objective To investigate the feasibility of Mycoplasma pneumoniae-simultaneous amplification and testing (MP-SAT)as a monitoring index for children with Mycoplasma pneumoniae pneumonia (MPP). Methods 178 hospitalized children with community-acquired pneumonia (CAP)in our hospital from October 2017 to October 2018 were selected and divided into two groups, namely MPP group (n=80)and non-MPP group (n=98). Serum MP antibody (MP-Ab)and throat swab MP-RNA were detected separately. The MP-Ab test was used as a reference for the analysis of accuracy of MP-SAT for MPP diagnosis. The MPP patients with positive MP-SAT and positive MP-Ab were observed dynamically. The detection rates of MP-SAT and MP-Ab in different treatment time points were compared. The correlation of MP-SAT negative time with clinical recovery time, clinical symptoms, laboratory parameters and chest X-ray was analyzed. Results The ratio of inconsistent MP-SAT and MP-Ab results was 60.00% (48/80)and 19.39% (19/98)in the MPP group and the non-MPP group, respectively. The MP-SAT and MP-Ab were statistically different in terms of specificity and positive predictive value (P<0.05), while no difference was found in the sensitivity and negative predictive value (P>0.05). Both MP-SAT and MP-Ab were positive in 28 cases (35.00%). The positive rate of MP-SAT was decreased with the prolongation of treatment time (P<0.05), meanwhile the positive rate of MP-Ab was increased with the treatment time (P<0.05); the clinical recovery time of 28 cases was (3.11±0.88)weeks, and the MP-SAT negative time was (3.25±0.74)weeks, with no statistical difference (P>0.05). The long-term duration of MP-SAT was characterized by long duration of fever, high consolidation rate of X-ray chest radiograph, high CRP level, high LDH level, high percentage of neutrophils, and low percentage of lymphocytes (P<0.05). Conclusion MP-SAT, as a new generation of RNA live bacteria detection technology, has high value in monitoring the efficacy of Mycoplasma pneumonia in children, and it is worth promoting.
