OBJECTIVE To provide references for ensuring the safety of prescription preparation， dispensing， and use of parenteral nutrition solution， as well as for expanding the scope of pharmaceutical services provided by pharmacists in the Pharmacy Intravenous Admixture Services （PIVAS）. METHODS Under the guidance of PIVAS pharmacists， the rules for reviewing medical orders of parenteral nutrition in the PIVAS system and the information displayed on the infusion labels of finished parenteral nutrition solutions were refined. The process management of dispensing parenteral nutrition solution was strengthened， and detailed quality control and inspection rules were formulated. Additionally， Clinical Safety Monitoring Form for Finished Parenteral Nutrition Infusions was designed to conduct clinical monitoring and inspections for abnormalities in the finished infusions， infusion operations， and complications that may arise during the use of finished parenteral nutrition infusions. The implementation effects of the aforementioned optimization/inspection measures were evaluated by comparing data on the efficiency of medical order review for parenteral nutrition， the rate of irrational medical orders， the compliance rate of vascular access selection and infusion rate standardization， the rate of dispensing error， as well as the abnormalities occurring during clinical use， before and after the optimization/inspection initiatives were put into place. RESULTS The optimized prescription review system achieved automatic review of medical orders for parenteral nutrition， enhancing the efficiency of order review. The average time taken to review one parenteral nutrition medical order was reduced from approximately 1 minute to 10 seconds. The irrational rate of parenteral nutrition orders decreased by 31.87%. The dispensing error rate of parenteral nutrition decreased by 56.55%. The standard rate of vascular access selection and standard rate of infusion speed were increased by 13.29% and 3.54%， respectively. The PIVAS pharmacists identified and intervened in 5 abnormal cases out of 298 cases examined for use of parenteral nutrition solutions. CONCLUSIONS By optimizing the prescription review system， improving labeling information， and strengthening quality control inspections during both preparation and administration processes， PIVAS pharmacists have enhanced the safety of compounded parenteral nutrition solutions. This initiative has expanded the scope and depth of pharmaceutical care provided by dispensing pharmacists.

Sweat pores function is the ascending and descending of Qi. The human body maintains a continuous, holistic, and dynamic balance through the functioning of sweat pores as well as the Qi movement and transformation in the spleen, stomach, and triple energizer. Sweat pores play a crucial role in the generation and development of Zang-fu organs, essence and spirit, and body and orifices, as well as in the onset and progression of diseases. Oxidative stress significantly affects the regulation of inflammation in allergic rhinitis(AR), induces the pathological damage to nasal epithelial cells, and alters immune activity, serving as a key mechanism exacerbating AR symptoms. This mechanism closely aligns with the pathogenesis associated with dysfunction in the sweat pore-Qi-triple energizer system. In recent years, oxidative stress and antioxidants in AR have received increasing attention. Elevated levels of reactive oxygen species, fractional exhaled nitric oxide, and malondialdehyde have become key indicators for the early diagnosis of AR. Classical prescriptions, empirical prescriptions, and newly developed preparations of traditional Chinese medicine(TCM) for external use with anti-inflammatory, anti-allergic, and immune-regulatory effects via antioxidant pathways have demonstrated definite efficacy in treating AR. This provides a basis for understanding the pathogenesis of AR in TCM from a modern medical perspective. Therefore, this paper systematically examines the relationship between the sweat pore-Qi-triple energizer system and AR, incorporating the oxidative stress mechanism into the research on pathogenesis of the disorders. Furthermore, methods for treating AR in children are proposed with TCM preparations for external use which aimed at opening nasal sweat pores, dispersing, searching, channeling with aroma, warming, and dredging, regulating Qi movement in spleen, warming Yang Qi to promote urination, and clearing latent wind to inhibit liver depression.

BACKGROUND: The clinical impact of post-percutaneous coronary intervention (PCI) quantitative flow ratio (QFR) in patients treated with PCI for chronic total occlusion (CTO) was still undetermined. METHODS: All CTO vessels treated with successful anatomical PCI in patients from PANDA III trial were retrospectively measured for post-PCI QFR. The primary outcome was 2-year vessel-oriented composite endpoints (VOCEs, composite of target vessel-related cardiac death, target vessel-related myocardial infarction, and ischemia-driven target vessel revascularization). Receiver operator characteristic curve analysis was conducted to identify optimal cutoff value of post-PCI QFR for predicting the 2-year VOCEs, and all vessels were stratified by this optimal cutoff value. Cox proportional hazards models were employed to calculate the hazard ratio (HR) with 95% CI. RESULTS: Among 428 CTO vessels treated with PCI, 353 vessels (82.5%) were analyzable for post-PCI QFR. 31 VOCEs (8.7%) occurred at 2 years. Mean value of post-PCI QFR was 0.92 ± 0.13. Receiver operator characteristic curve analysis shown the optimal cutoff value of post-PCI QFR for predicting 2-year VOCEs was 0.91. The incidence of 2-year VOCEs in the vessel with post-PCI QFR < 0.91 (n = 91) was significantly higher compared with the vessels with post-PCI QFR ≥ 0.91 (n = 262) (22.0% vs. 4.2%, HR = 4.98, 95% CI: 2.32-10.70). CONCLUSIONS Higher post-PCI QFR values were associated with improved prognosis in the PCI practice for coronary CTO. Achieving functionally optimal PCI results (post-PCI QFR value ≥ 0.91) tends to get better prognosis for patients with CTO lesions.

Objective Cervical disc herniation(CDH)is one of the common orthopaedic diseases.With the in-depth study of it and the development of cervical implants,the establishment of cervical fusion animal models has become an indispensable part.Notably however,studies of the establishment and evaluation of cervical fusion animal models in China are currently lacking.This study aimed to provide a suitable animal model and evaluation scheme for implants for cervical spine-related research.Methods Small-tailed Han sheep were chosen for anterior cervical discectomy fusion(ACDF)after modified surgery,and a polyetheretherketone(PEEK)interbody fusion cage(Cage)(control group),3D-printed Ti6Al4V Cage(group 1),and new method Ti6Al4V Cage(group 2)were implanted in different cervical segments(C2/3～C4/5)in each sheep,respectively.Hematology and histopathological analyses were carried out after surgery to evaluate recovery of sheep and the biosafety of the materials.Bone in-growth and bone fusion were assessed by X-ray,computed tomography(CT),Micro-CT and quantitative analysis,hard tissue section staining,and biomechanical tests.Results The modified ACDF ovine model was established successfully.There were no significant differences in important hematology indexes(P＞0.05)and histopathological analysis showed no pathological changes,such as inflammatory cell infiltration.The implants had good biosafety.Furthermore,X-ray and CT examinations showed that the position of internal fixation and the interbody fusion were good.Micro-CT and quantitative analysis at 3 and 6 months after operation showed that compared with PEEK Cage group,the bone volume/total volume and trabecular number were significantly increased(P＜0.01)while the trabecular spacing was significantly decreased in the new method Ti6Al4V and 3D-printed Ti6Al4V groups compared with the PEEK Cage group(P＜0.01).Moreover,the new method new method Ti6Al4V Cage group had more bone growth(P＜0.01).Hard tissue section staining demonstrated that the pores of the new method Ti6Al4V Cage and 3D-printed Ti6Al4V Cage had obvious bone growth and relatively dense pores in the new method Ti6Al4V and 3D-printed Ti6Al4V groups,and the combination was slightly better than that of PEEK Cage.Biomechanical evaluation indicated that the new method Ti6Al4V Cage and 3D-printed Ti6Al4V Cage reduced the range of cervical flexion-extension,lateral bending,and axial rotation(P＜0.05)compared with the PEEK cage,as well as enhancing the stability of the cervical vertebra,and the new method Ti6Al4 V Cage was more advantageous(P＜0.05).Conclusions After the establishment of the modified ACDF ovine model,reasonable and effective assessment method were used to demonstrate the suitability and effectiveness of the model and the good biosecurity of all three Cage materials.Compared with the PEEK Cage,the new method Ti6Al4V Cage and 3D-printed Ti6Al4V Cages showed better performances in terms of bone growth and bone fusion,which could enhance the stability of the cervical vertebrae.The new method Ti6Al4V Cage was particularly advantageous.

To evaluate the effectiveness and safety of 8-ring assisted traction in endoscopic submucosal dissection (ESD), a total of 13 patients with 15 gastric lesions who underwent 8-ring traction-assisted ESD in Nanjing Drum Tower Hospital from July 2021 to January 2022 were included in the retrospective cohort study. All patients successfully completed the operation. The median procedure time was 56 min, and the dissected area per unit time was 0.20±0.02 cm 2/min. The en bloc resection rate, the complete resection rate and the curative resection rate were 93.3% (14/15), 80.0% (12/15) and 80.0% (12/15), respectively. There were no ESD-related complications, such as delayed bleeding or intraperative and postoperative perforation. No deaths occurred. As a novel internal traction technology, 8-ring traction method is simple to operate, providing a good field of vision during ESD to improve the dissection efficiency and reduce complications, which is worthy of further clinical research and promotion.

Objective To examine the changing antimicrobial resistance profile of Enterobacter spp.isolates in 53 hospitals across China from 2015 t0 2021.Methods The clinical isolates of Enterobacter spp.were collected from 53 hospitals across China during 2015-2021 and tested for antimicrobial susceptibility using Kirby-Bauer method or automated testing systems according to the CHINET unified protocol.The results were interpreted according to the breakpoints issued by the Clinical & Laboratory Standards Institute(CLSI)in 2021(M100 31st edition)and analyzed with WHONET 5.6 software.Results A total of 37 966 Enterobacter strains were isolated from 2015 to 2021.The proportion of Enterobacter isolates among all clinical isolates showed a fluctuating trend over the 7-year period,overall 2.5％in all clinical isolates amd 5.7％in Enterobacterale strains.The most frequently isolated Enterobacter species was Enterobacter cloacae,accounting for 93.7％(35 571/37 966).The strains were mainly isolated from respiratory specimens(44.4±4.6)％,followed by secretions/pus(16.4±2.3)％and urine(16.0±0.9)％.The strains from respiratory samples decreased slightly,while those from sterile body fluids increased over the 7-year period.The Enterobacter strains were mainly isolated from inpatients(92.9％),and only(7.1±0.8)％of the strains were isolated from outpatients and emergency patients.The patients in surgical wards contributed the highest number of isolates(24.4±2.9)％compared to the inpatients in any other departement.Overall,≤ 7.9％of the E.cloacae strains were resistant to amikacin,tigecycline,polymyxin B,imipenem or meropenem,while ≤5.6％of the Enterobacter asburiae strains were resistant to these antimicrobial agents.E.asburiae showed higher resistance rate to polymyxin B than E.cloacae(19.7％vs 3.9％).Overall,≤8.1％of the Enterobacter gergoviae strains were resistant to tigecycline,amikacin,meropenem,or imipenem,while 10.5％of these strains were resistant to polycolistin B.The overall prevalence of carbapenem-resistant Enterobacter was 10.0％over the 7-year period,but showing an upward trend.The resistance profiles of Enterobacter isolates varied with the department from which they were isolated and whether the patient is an adult or a child.The prevalence of carbapenem-resistant E.cloacae was the highest in the E.cloacae isolates from ICU patients.Conclusions The results of the CHINET Antimicrobial Resistance Surveillance Program indicate that the proportion of Enterobacter strains in all clinical isolates fluctuates slightly over the 7-year period from 2015 to 2021.The Enterobacter strains showed increasing resistance to multiple antimicrobial drugs,especially carbapenems over the 7-year period.

Objective:To investigate the expression level and clinical significance of HMGB1-TLR4-IL-23-IL-17A axis in se-rum of patients with psoriasis vulgaris.Methods:The expression levels of HMGB1,TLR4,IL-23 and IL-17A in serum of 60 patients with psoriasis vulgaris and 30 healthy volunteers were detected by ELISA.In addition,the differences of cytokines expression levels between moderate and severe psoriasis patients were compared,and the correlation between the expression levels of cytokines and the disease severity expressed by psoriasis area and severity index(PASI)were analyzed.The differences of expression levels of HMGB1-TLR4-IL-23-IL-17A axis before and after IL-17A inhibitor induction treatment were detected and compared in 22 moderate to severe psoriasis patients reached PASI75 and higher level.Results:The expression levels of serum HMGB1,TLR4,IL-23 and IL-17A in patients with psoriasis were obviously higher than those of healthy controls.Moreover,the expression levels of serum HMGB1,TLR4,IL-23 and IL-17A were even elevated in severe patients compared with moderate patients,and were positively correlated with PASI score.After induction treatment of IL-17A inhibitor,the expression levels of HMGB1-TLR4-IL-23-IL-17A aixs decreased significantly in serum of patients with psoriasis.Conclusion:HMGB1-TLR4-IL-23-IL-17A axis is highly expressed in patients with psoriasis vulgaris,and positively related to the disease severity,which may be involved in the disease process of psoriasis vulgaris and provide a new idea for the immunotherapy of psoriasis.

Objective:To explore the gene mutations of Langerhans cell histiocytosis in children,and to analyze the correlation of BRAF V600E mutation with clinical features and prognosis of LCH,so as to provide reference for clinical diagnosis and treatment. Methods:Fluorescence PCR was used to detect gene mutations in paraffin-embedded tissue samples from 78 children with LCH,and the correlation of BRAF V600E mutation with clinical characteristics and prognosis of LCH in children was analyzed. Results:Among the 78 children,41 cases (52.6％) had BRAF V600E mutation,8 cases (10.3％) had MAP2K1 mutation,1 case (1.3％) had BRAF Exon 12 mutation,1 case (1.3％) had ARAF mutation,and 1 case (1.3％) had PIK3CA mutation. BRAF V600E mutation was not significantly correlated with sex,age,multisystem involvement,risk-organ involvement,CNS-risk lesions,and early treatment response in children with LCH (P>0.05),and it was also not significantly correlated with the recurrence and event-free survival (EFS) of children with LCH (P>0.05). Conclusion:LCH is an inflammatory myeloid tumor. BRAF V600E mutation is not correlated with clinical features,early treatment response,recurrence and prognosis of LCH.

Objective:To evaluate the efficacy and outcomes of early removal of lumen-apposing metal stent (LAMS) in the treatment of pancreatic wall-off necrosis (WON).Methods:A retrospective analysis was performed on 51 patients with WON who underwent endoscopic ultrasound (EUS)-guided transluminal drainage (ETD) and direct endoscopic necrosectomy (DEN) using LAMS at Nanjing Drum Tower Hospital from January 2018 to December 2022. Patients were divided into the early removal group (within two weeks, n=24) and the traditional removal group (after two weeks, n=27) based on the timing of LAMS removal. The short-term effects, safety and long-term outcomes of WON were compared between the two groups. Results:The technical success rate of LAMS placement in 51 patients reached 100%, and all patients underwent ETD and DEN. The median number of necrosectomy sessions in the early removal group was significantly lower than in the traditional removal group, 2.0 sessions vs 3.0 sessions and the difference was statistically significant ( P<0.05). Postoperatively, 15.7% of patients required percutaneous catheter drainage (PCD) and 5.9% required surgery, with no significant difference between the two groups. The clinical success rate and mortality rate in the early removal group were 79.2% and 8.3%, respectively, compared to 81.5% and 3.7% in the traditional removal group, with no statistically significant difference. In terms of safety, the early removal group exhibited a significantly lower rate of adverse events during stent retention with statistically significant difference (12.5% vs 37.0%, P<0.05) compared to the traditional removal group. A total of 46 patients were followed up for six months. In the early removal group, the rates of disease recurrence, need for endoscopic reintervention and occurrence of long-term complications were 20.0%, 10.0% and 20.0%, respectively. These rates did not show a significant increase compared to the traditional removal group, which were 7.7%, 3.8% and 38.5%, respectively, without significant differences between the groups. Conclusions:In the treatment of WON, early removal of LAMS is safe and effective to a certain extent. In comparison to the traditional practice of removing LAMS after two weeks, early removal does not reduce clinical success rates, nor does it increase the rates of disease-related mortality, recurrence, or long-term complications. On the contrary, it may reduce the occurrence of adverse events during stent retention and decrease the number of necrosectomy procedures subsequently.
