OBJECTIVE To provide reference for improving the pre-prescription review system and reducing the occurrence of medication error by analyzing the drug-related problems （DRPs） in the pre-prescription review orders of pediatric outpatient clinics using the Pharmaceutical Care Network Europe （PCNE） classification system. METHODS The data of pre-prescription review orders were retrospectively collected from outpatient department of Shanghai Children’s Medical Center， Shanghai Jiao Tong University School of Medicine from July 2022 to June 2023； DRPs in the pre-prescription review orders were classified and summarized by using the PCNE classification system （version 9.1）， and then analyzed in terms of types and causes of issues， and the acceptance of interventions. RESULTS A total of 66 017 DRPs orders were included， involving 41 165 patients. The proportion of DRPs orders in children aged ≤5 years old was the highest （58.25%）， followed by children aged 6-12 years old （33.52%）； the department with the highest proportion of DRPs was internal medicine of pediatrics department （71.41%）； the department with the highest incidence of DRPs was thoracic surgery department （9.73%）； top three drug categories of DRPs orders were systemic anti- infective drugs （25.26%）， Chinese patent medicines （24.74%） and respiratory drugs （22.38%）. Referring to PCNE classification system， the types of DRPs mainly focused on treatment safety （64.86%）； the reasons of DRPs orders mainly focused on dose selection （82.09%）， of which 41.26% were due to excessive drug dosage； 92.13% of interventions could be accepted and fully executed by doctors. CONCLUSIONS DRPs orders identified by the pre-prescription review system can be effectively analyzed by using PCNE classification system. Pharmacists should focus on medication use in children aged ≤5 years old， update and develop personalized prescription review rules timely， and meet the rational needs of clinical medication for children.

Objective: To reveal the therapeutic effects of moxibustion in collagen-induced arthritis (CIA) rat models using the combined analysis of plasma and synovial membrane lipidomic profiling and to enhance the understanding of how moxibustion affects lipid metabolism in rheumatoid arthritis (RA). Methods: A total of 32 male Sprague-Dawley (SD) rats were randomly assigned to four groups: control, moxibustion control (MC), model, and moxibustion model (MM) groups, with 8 rats in each group. CIA was induced in SD rats by two immunizations. The paw volume was measured before the induction of CIA. Following induction, after assessing paw volume and arthritis index (AI) scores, the MC and MM groups received treatment at bilateral Shenshu (BL23) and Zusanli (ST36) acupoints for 10 min per acupoint. The intervention included three treatment courses, each spanning 6 d and followed by a 1-d interval. Paw volume and AI scores were assessed after each treatment course. After the completion of the three treatment courses, serum, plasma, synovial tissue, and ankle joint samples were collected. Enzyme-linked immunosorbent assay (ELISA) was employed to quantify the levels of interleukin (IL)-6 and tumor necrosis factor (TNF)-α in serum. Hematoxylin and eosin (HE) staining was performed for histopathological examination of the ankle joint tissues. Meanwhile, ultra-high-performance liquid chromatography coupled with Q-Exactive Orbitrap mass spectrometry (UHPLC-Q-Exactive Orbitrap MS) was utilized to analyze the plasma and synovial tissue samples. In addition, multivariate statistical analysis was performed to identify differential lipid metabolites, and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis was applied to explore metabolic pathways modulated by moxibustion therapy. Results: No significant difference in hind paw volume and AI scores was observed among the groups (P > 0.05). After CIA induction, model group showed increased hind paw volume and AI scores compared with control group (P < 0.05), which were significantly reduced after moxibustion treatment in MM group compared with model group (P < 0.05). The levels of IL-6 and TNF-α were significantly higher in model and MM groups compared with control group (P < 0.05), but were lower in MM group than those in model group (P < 0.05). Histopathological analysis showed improved cartilage and reduced inflammation in MM group. A total of 33 differential lipid metabolites in the plasma and 24 in the synovial membranes of CIA rat models were identified when compared with control group. Among these lipid metabolites, 31 in the plasma and all 24 in the synovial membranes were regulated by moxibustion treatment. Pathological analysis revealed upregulation of diacylglycerol (DG) and fatty acid (FA) levels, alongside downregulation of lysophosphatidylcholine (LPC), phosphatidylcholine (PC), and phosphatidylethanolamine (PE). Under physiological conditions, the treatment specifically reduced LPC and PC levels. Pathway enrichment analysis revealed that moxibustion predominantly affected α-linolenic acid, glycerophospholipid, and sphingolipid metabolism under pathological conditions. Under physiological conditions, the regulation was centered around α-linolenic acid and glycerophospholipid metabolism. Conclusion The RA rat models exhibited significant lipid metabolic disturbances. Moxibustion alleviated paw swelling, reduced AI scores, modulated inflammatory cytokine levels, and partially corrected the altered levels of multiple lipid metabolites. The potential metabolic pathways implicated in the regulation of lipid metabolism under both physiological and pathological conditions include α-linolenic acid, glycerophospholipid, and sphingolipid metabolism.

Objective To investigate the clinical efficacy of artificial dura mater and epidermal growth factor in the repair of tympanic membrane perforation after endoscopic tympanic membrane repair.Methods 58 patients with tympanic membrane perforation were randomly divided into two groups,29 cases in each.Group A was repaired with gelatin sponge,group B was repaired with artificial dura mater and epidermal growth factor.The tympanic membrane healing was reviewed every month,and the pure tone audiometry was reviewed after 3 months.Results The success rate of repair in group A was 34.48%(10/29),and that in group B was 75.86%(22/29).The difference was statistically significant(P<0.05).The air-bone gap in group A was improved by(7.32±2.68)dB HL,and that in group B was improved by(21.77±4.65)dB HL.The difference was statistically significant(P<0.05).Conclusion Artificial dura mater is a suitable tympanic membrane regeneration scaffold.Epidermal growth factor can promote the healing of tympanic membrane perforation.The combination of the two is a feasible treatment for tympanic membrane repair.

Objective:To investigate the clinical features and therapeutic efficacy of patients with hereditary leiomyomatosis and renal cell carcinoma(RCC) syndrome-associated RCC (HLRCC-RCC) in China.Methods:The clinical data of 119 HLRCC-RCC patients with fumarate hydratase (FH) germline mutation confirmed by genetic diagnosis from 15 medical centers nationwide from January 2008 to December 2021 were retrospectively analyzed. Among them, 73 were male and 46 were female. The median age was 38(13, 74) years. The median tumor diameter was 6.5 (1.0, 20.5) cm. There were 38 cases (31.9%) in stage Ⅰ-Ⅱand 81 cases (68.1%) in stage Ⅲ-Ⅳ. In this group, only 11 of 119 HLRCC-RCC patients presented with skin smooth muscle tumors, and 44 of 46 female HLRCC-RCC patients had a history of uterine fibroids. The pathological characteristics, treatment methods, prognosis and survival of the patients were summarized.Results:A total of 86 patients underwent surgical treatment, including 70 cases of radical nephrectomy, 5 cases of partial nephrectomy, and 11 cases of reductive nephrectomy. The other 33 patients with newly diagnosed metastasis underwent renal puncture biopsy. The results of genetic testing showed that 94 patients had FH gene point mutation, 18 had FH gene insertion/deletion mutation, 4 had FH gene splicing mutation, 2 had FH gene large fragment deletion and 1 had FH gene copy number mutation. Immunohistochemical staining showed strong 2-succinocysteine (2-SC) positive and FH negative in 113 patients. A total of 102 patients received systematic treatment, including 44 newly diagnosed patients with metastasis and 58 patients with postoperative metastasis. Among them, 33 patients were treated with tyrosine kinase inhibitor (TKI) combined with immune checkpoint inhibitor (ICI), 8 patients were treated with bevacizumab combined with erlotinib, and 61 patients were treated with TKI monotherapy. Survival analysis showed that the median progression-free survival (PFS) of TKI combined with ICI was 18 (5, 38) months, and the median overall survival (OS) was not reached. The median PFS and OS were 12 (5, 14) months and 30 (10, 32) months in the bevacizumab combined with erlotinib treatment group, respectively. The median PFS and OS were 10 (3, 64) months and 44 (10, 74) months in the TKI monotherapy group, respectively. PFS ( P=0.009) and OS ( P=0.006) in TKI combined with ICI group were better than those in bevacizumab combined with erlotinib group. The median PFS ( P=0.003) and median OS ( P=0.028) in TKI combined with ICI group were better than those in TKI monotherapy group. Conclusions:HLRCC-RCC is rare but has a high degree of malignancy, poor prognosis and familial genetic characteristics. Immunohistochemical staining with strong positive 2-SC and negative FH can provide an important basis for clinical diagnosis. Genetic detection of FH gene germ line mutation can confirm the diagnosis. The preliminary study results confirmed that TKI combined with ICI had a good clinical effect, but it needs to be confirmed by the results of a large sample multi-center randomized controlled clinical study.

Objective:To investigate the predictive value of pregnancy-associated plasma protein A(PAPP-A),fasting blood glucose(FPG),body mass index(BMI)and age in gestational diabetes mellitus(GDM)during the first trimester.Methods:A retrospective analysis was performed on 792 pregnant women who underwent pre-natal examination and delivered in Sichuan Provincial Maternal and Child Health Care Hospital from December 2021 to June 2022.They were divided into GDM group(232 cases)and control group(560 cases)according to whether they had GDM.The clinical data,serum PAPP-A median multiple(PAPP-A MoM)in early pregnancy and FPG levels were compared between the two groups.The indicators with statistical significance in univariate analy-sis were included in multivariate Logistic regression analysis to analyze the related factors affecting the occurrence of GDM.The receiver operating curve(ROC)and area under the curve(AUC)of different indexes were plotted to compare the efficacy of GDM prediction.Results:①The age,pre pregnancy BMI,early pregnancy FPG and the proportion of assisted reproductive technology in GDM group were higher than those in control group,and the differences were statistically significant(P＜0.05).The early pregnancy PAPP-A MoM level in GDM group was lower than that in control group,and the difference was statistically significant(P＜0.05).②Multivariate Logistic regression analysis showed that older age,lager pre-pregnancy BMI and lager FPG in the first trimester were in-dependent risk factors for GDM occurrence(OR＞1,P＜0.05),while an increase of PAPP-A MoM in the first tri-mester was a protective factor(OR＜1,P＜0.05).③ROC showed that the combination of PAPP-A MoM in early pregnancy,FPG in early pregnancy,BMI in pre-pregnancy and age had the highest AUC(0.752)when predicting GDM,with a sensitivity of 55.6％and a specificity of 84.3％.Conclusions:The combined screening of serologi-cal(PAPP-A +FPG)and clinical data(pre-pregnancy BMI +age)in early pregnancy has a high clinical application prospect and can be popularized.

Objectives:To evaluate the valvular and cardiac function,cardiac reverse remodeling at 6-month after transcatheter edge-to-edge repair(TEER)for patients with functional and degenerative mitral valve regurgitation,and summarize the experience of echocardiography application. Methods:The clinical data of 93 patients with moderate to severe mitral regurgitation(MR)treated with TEER and completed 6-month follow-up in Yunnan Fuwai Cardiovascular Hospital from July 2022 to February 2023 were retrospectively analyzed.Patients were divided into functional mitral regurgitation(FMR)and degenerative mitral regurgitation(DMR)groups according to MR etiology.The valve characteristic parameters,as well as valvular function,chamber volume and cardiac functional parameters before and at 6 months after operation were compared.The key points of echocardiography application were summarized. Results:Among all patients,71 were FMR and 22 were DMR.There were differences in valve structure between the two groups.Mitral TEER were successfully accomplished and all patients completed 6-month follow-up.The key points of echocardiography application included:valve structure analysis,atrial septal puncture location,device delivery process monitoring and image optimization during clamping process.The mitral regurgitation grade and NYHA grade were significantly improved in all patients at 6 months after TEER(P<0.05),and the mean mitral valve pressure gradient was higher than that before operation(P<0.05).Left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV)and left atrial volume index in FMR group were significantly decreased(P<0.05),while left ventricular and left atrial volume in DMR group remained unchanged(P>0.05).There were no significant changes in left ventricular ejection fraction and left ventricular global strain in both groups during the observation period(P>0.05).The changes of LVEDV and LVESV before and after operation were more significant in FMR group than those in DMR group(P<0.05). Conclusions:Mitral TEER can reduce the degree of regurgitation and improve cardiac function in the early postoperative period for moderate and severe MR patients with different etiologies.There are differences in preoperative valve structure and postoperative cardiac reverse remodeling between FMR and DMR patients.Echocardiography is an important imaging technique for the evaluation and monitoring process before,during and post mitral TEER.

Objective To explore the correlations of evaluations of right heart function parameters in patients with Ebstein anomaly(EA)using echocardiography and cardiac MRI.Methods Data of transthoracic echocardiography and cardiac MRI in 32 patients with EA confirmed by operation were retrospectively analyzed.The correlations of cardiac cavity size,right ventricular function and strain parameters obtained using echocardiography and the functional right ventricular(fRV)ejection fraction(EF)measured using MRI were explored.Results MRI fRV-EF in 32 cases of EA was(23.20± 7.61)％.Among echocardiographic parameters in 32 cases of EA,fractional area change(FAC)of fRV(r=0.347,P=0.015)was slightly,while global longitudinal strain(GLS)of fRV(r=0.801,P＜0.001)was highly positively correlated with MRI fRV-EF,respectively,whereas atrialized right ventricle(aRV)area/fRV area(r=-0.730,P=0.007)was highly negatively,aRV area/left ventricular area(r=-0.450,P=0.042)and right ventricular anterior-posterior diameter(r=-0.650,P=0.022)were both moderately negatively correlated with MRI fRV-EF.Both the left ventricular eccentricity index(r=-0.347,P=0.049)and Glasgow outcome scale extended(r=-0.336,P=0.024)obtained with echocardiography were slightly negatively correlated MRI fRV-EF.Conclusion Right heart function parameters in EA patients obtained with echocardiography were correlated with those of MRI fRV-GLS,among which aRV area/fRV area were highly positively correlated with MRI fRV-EF,hence having great value for evaluating right heart function in EA patients.

Objective To explore the efficacy of modified three-line tension reduction and precise delayed tamponade in nasal septum correction.Methods From January 2021 to January 2023,a total of 94 patients who underwent nasal septum deviation surgery in Department of Otolaryngology,Hangzhou Hospital of Traditional Chinese Medicine,Zhejiang University of Traditional Chinese Medicine were randomly divided into group A and group B,with 47 cases in each group.Patients in group A were treated with traditional nasal septum three-line tension reduction;Patients in group B were treated with modified three-line tension reduction of nasal septum,and iodoform gauze was accurately filled in the deviated part after bilateral nasal tamponade was removed for 2 weeks.The operation time,intraoperative nasal septum mucosal injury and intraoperative blood loss were compared between the two groups.Subjective symptoms were scored by nasal obstruction symptom evaluation(NOSE).Nasal septum deviation was evaluated by nasal endoscopy.Results The number of cases of mucosal injury in group A was more than that in group B;The operation time of group A was longer than that of group B,and the difference was statistically significant(P<0.05).The amount of bleeding in group A was more than that in group B,and the difference was statistically significant(P<0.05).The nasal obstruction symptoms of two groups were improved after operation,and the improvement effect of nasal obstruction symptoms in group B was better,the difference was statistically significant(P<0.05).The deviation of nasal septum in both groups was improved,and the improvement of nasal septum shaping in group B was better than that in group A,the difference was statistically significant(P<0.05).Conclusion The modified three-line tension reduction under nasal endoscopy can achieve the same effect as the traditional three-line tension reduction nasal septum correction.At the same time,it can shorten the operation time,reduce the amount of bleeding,reduce the risk of nasal septum perforation,and accurately delay the micro-filling for about 2 weeks.It can avoid the elastic retraction of nasal septum cartilage and improve the surgical effect.
