Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

Objective To observe the effects of abdominal penetrating moxibustion combined with acupuncture at the"four chong points"on balance,walking function and trunk control in patients recovering from stroke.Methods Seventy-eight patients recovering from stroke were randomly divided into an observation group and a control group,with 39 patients in each group.The control group was given conventional rehabilitation exercises,while the observation group was given abdominal penetrating moxibustion combined with acupuncture at the"four chong points"on the basis of the control group.Both groups were treated for 2 consecutive months.After 2 months of treatment,the clinical efficacy of the two groups was evaluated,and the changes in the Berg Scale score and the Timed Up and Go Test(TUGT)were observed before and after treatment.The changes in the National Institutes of Health Stroke Scale(NIHSS)scores were compared before and after treatment between the two groups.The Sheikh Trunk Control Scale scores were also evaluated.Results(1)The total effective rate of the observation group was 94.87%(37/39),and the total effective rate of the control group was 80.00%(31/39),and the efficacy of the observation group was superior to that of the control group,and the difference was statistically significant(P＜0.05).(2)After treatment,the Berg scores of the patients in the two groups were significantly increased(P＜0.05),and the Berg scores of the observation group were higher than those of the control group,and the difference was statistically significant(P＜0.05).(3)After treatment,the TUGT time and NIHSS score of patients in the two groups were significantly improved(P＜0.05),and the TUGT time of the observation group was shorter than that of the control group,and the NIHSS score was lower than that of the control group,and the difference was statistically significant(P＜0.05).(4)After treatment,the Sheikh trunk control scores of the two groups were significantly increased(P＜0.05),and the Sheikh trunk control score of the observation group was higher than that of the control group,and the difference was statistically significant(P＜0.05).Conclusion Abdominal penetrating moxibustion method combined with acupuncture at the four chong points for the treatment of stroke recovery can effectively restore the patients'balance and walking function,improve the patients'trunk control ability,and the therapeutic effect is precise.

AIM:Using bioinformatics analysis and experiment validation to explore the differential expres-sion genes related to abnormal lipid metabolism in hepatocellular carcinoma(HCC)and the molecular mechanism of pachymaran affecting pyroptosis through squalene epoxidase(SQLE)/nucleotide-binding oligomerization domain-like re-ceptor protein 3(NLRP3)/gasdermin D(GSDMD)signaling pathway.METHODS:(1)The GEO,GSEA,DAVID,STRING and GEPIA databases were employed to screen abnormal lipid metabolism-related differentially expressed genes in HCC.(2)The tumor tissues from HCC patients(n=9)were collected to verify the differential expression of SQLE.(3)The inhibitory effect of pachymaran on the viability of human HCC cell line HepG2 was measured by CCK-8 assay.(4)The HepG2 cells were divided into control group and pachymaran(800 mg/L)group.The cell migration was analyzed by wound-healing assay,and RT-qPCR was used to measure SQLE mRNA expression.(5)The HepG2 cells with overexpres-sion of SQLE(OE-SQLE)were divided into 5 groups as follows:control group,overexpression negative control(OE-NC)group,OE-SQLE group,OE-NC+pachymaran group,and OE-SQLE+pachymaran group.The mRNA and protein expres-sion levels of SQLE and pyroptosis-related factors were determined by RT-qPCR and Western blot.Colorimetric method and ELISA were used to measure lactate dehydrogenase(LDH),interleukin-1β(IL-1β)and IL-18 levels.The necrosis of HepG2 cells was analyzed by flow cytometry.RESULTS:The SQLE gene was screened through bioinformatics analysis,and its mRNA expression was significantly increased in tumor tissues from HCC patients(P＜0.01).In cell experiments,treatment with 800 mg/L pachymaran for 48 h had a significant inhibitory effect on HepG2 cell viability,and the expres-sion of SQLE mRNA was reduced(P＜0.01).After overexpression of SQLE,the mRNA and protein levels of pyroptosis-re-lated factors,necrotic rate,and LDH,IL-1β and IL-18 levels were significantly decreased(P＜0.05).After treatment with pachymaran,the above indicators were significantly increased(P＜0.05).CONCLUSION:The SQLE is abnormal-ly highly expressed in HCC,and pachymaran can affect the growth of HCC cells by activating the NLRP3/GSDMD pyropto-sis pathway through SQLE.

Objective:To assess the feasibility and efficacy of hypofractionated radiotherapy with simultaneous integrated boost (HFRT-SIB) for patients with non-osteogenic spinal metastases who were not suitable for stereotactic body radiotherapy (SBRT).Methods:A totoal of 26 spinal metastatic lesions in 24 patients with non-osteogenic spinal metastases admitted to Beijing Luhe Hospital affiliated to Capital Medical University from March 2020 to April 2023 were retrospectively analyzed. In our institution, a higher-dose fractionated regimen for spinal metastases was introduced, at a dose of 3 Gy/f ×10 times (5 times a week, once a day) to the clinical target volume (CTV), and simultaneous integrated boost (SIB) of 4 Gy/f ×10 times (5 times a week, once a day) to the gross tumor volume (GTV). The primary endpoint was the overall relief (OR) rates of pain at 12 and 24 weeks post-radiotherapy, while secondary endpoints included the pain response time and duration of pain relief, the incidence of adverse events post-radiotherapy, and the 1-year overall survival (OS) rate. The differences before and after treatment were analyzed by Wilcoxon signed-rank test. OS was assessed using Kaplan-Meier method.Results:The median follow-up was 11.7 (8.0, 17.0) months. At 12 weeks post-radiotherapy, 92% (22/24) of patients achieved OR, and 81% (17/21) obtained OR at 24 weeks post-radiotherapy. The median pain response time was 4 (3, 5) d. At the last follow-up, 42% (10/24) of patients maintained pain relief for over 1 year, with a median duration of pain relief up to 11.0 (6.0, 16.9) months. The 1-year OS rate was 66.3%, and no patients experienced grade 3 or higher acute or chronic adverse events.Conclusion:HFRT-SIB can effectively alleviate pain, and achieve sustained pain control, and does not lead to severe adverse effects in patients with non-osteogenic spinal metastases.

Objective:To explore the related factors of vascular complications after liver transplantation in children.Methods:This is a retrospective case series research. The clinical data of 89 pediatric liver transplant patients admitted to the Organ Transplantation Center, the Affiliated Hospital of Qingdao University from January 2016 to March 2024 were collected retrospectively. This study included 44 males and 45 females,aged from 4 months to 17 years. The ratio of graft to recipient weight was 0.6% to 7.7%. The primary diseases included 48 cases of biliary atresia and 41 cases of non-biliary atresia. The Wilcoxon rank sum test, χ2 test, and Fisher′s exact probability method were used for data analysis. Multivariate Logistic regression was used to analyze the related factors of vascular complications. Results:All 89 children with liver transplantation completed surgery successfully. There were 8 cases of arterial complications after surgery, including 6 cases of hepatic artery thrombosis and 2 cases of hepatic artery stenosis. There were 16 cases of portal vein complications after surgery, including 9 cases of portal vein stenosis and 7 cases of portal vein thrombosis. The results of univariate analysis showed that the age of the recipient ≤1 year was the relevant factor for hepatic arterial complications( χ 2=4.772, P=0.029). The age of the recipient ≤1 year, the age of the donor, the hepatic phase, and the time of cold ischemia were the relevant factors for the occurrence of portal vein complications( χ 2=7.270, Z=388.500, Z=838.000, Z=894.500;all P<0.05). The results of multivariate analysis showed that age(≤1 year vs. >1 year) and duration of cold ischemia(every additional 1 hour) were independent related factors for portal vein complications after liver transplantation in children(both P<0.05). Conclusion:Children aged ≤1 year and with prolonged cold ischemia are more likely to develop portal vein complications after liver transplantation.

As a major global public health problem, pulmonary diseases threaten human life and health while causing a huge economic burden. The messenger RNA (mRNA)-based inhalation preparation, which effectively targets pulmonary cells can overcome the problems of traditional therapy, such as high side effects, low pulmonary bioavailability, and difficulty in synthesizing target proteins in vitro, thus providing new ideas for the treatment of pulmonary diseases. However, as the lung structure is complex and mRNA has trouble entering cells, researchers have been attempting to develop a suitable nano delivery system for higher delivery efficiency. This review introduces the barriers to pulmonary delivery, discusses the recent research development of the mRNA pulmonary delivery systems, including lipid nanoparticles, polymeric nanoparticles, polypeptides and exosomes, summarizes their limitations and looks forward to the application of mRNA inhalation preparations.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Glioblastoma(GBM)is a lethal cancer with limited therapeutic options.Dendritic cell(DC)-based cancer vaccines provide a promising approach for GBM treatment.Clinical studies suggest that other immu-notherapeutic agents may be combined with DC vaccines to further enhance antitumor activity.Here,we report a GBM case with combination immunotherapy consisting of DC vaccines,anti-programmed death-1(anti-PD-1)and poly I:C as well as the chemotherapeutic agent cyclophosphamide that was integrated with standard chemoradiation therapy,and the patient remained disease-free for 69 months.The patient received DC vaccines loaded with multiple forms of tumor antigens,including mRNA-tumor associated antigens(TAA),mRNA-neoantigens,and hypochlorous acid(HOCl)-oxidized tumor lysates.Furthermore,mRNA-TAAAs were modified with a novel TriVac technology that fuses TAAs with a destabilization domain and inserts TAAs into full-length lysosomal associated membrane protein-1 to enhance major histo-compatibility complex(MHC)class Ⅰ and Ⅱ antigen presentation.The treatment consisted of 42 DC cancer vaccine infusions,26 anti-PD-1 antibody nivolumab administrations and 126 poly I:C injections for DC infusions.The patient also received 28 doses of cyclophosphamide for depletion of regulatory T cells.No immunotherapy-related adverse events were observed during the treatment.Robust antitumor CD4+and CD8+T-cell responses were detected.The patient remains free of disease progression.This is the first case report on the combination of the above three agents to treat glioblastoma patients.Our results suggest that integrated combination immunotherapy is safe and feasible for long-term treatment in this patient.A large-scale trial to validate these findings is warranted.

Objective:To construct a virtual simulation training platform for peripheral inserted central catheter (PICC) catheterization and discuss its application in clinical training.Methods:A total of 118 nurses who attended the PICC professional and technical advanced training courses in a province in 2020 and 2021 were enrolled in this study. In 2020, the training was conducted in the form of theoretical teaching combined with practical training ( n=51), and in 2021, virtual simulation platform was introduced as a supplement on the basis of the original training ( n=67). SPSS 23.0 was used for independent-samples t-test to compare the theoretical and operational assessment results of the two years and evaluate the application effect of the platform. Through the satisfaction survey and learning log, the nurses' experience of using the platform was understood. Results:The theoretical performance and the operational performance of nurses who participated in the training in 2021 were (96.56±3.17) and (94.06±2.16) respectively, and the operational performance was better than that of nurses who participated in the training in 2020 ( t=-11.37, P<0.001), and the difference in theoretical performance was not statistically significant ( t=0.17, P=0.853). In 2021, 63 nurses (94.0%) who used the virtual simulation platform believed that the platform could assist to improve the training effect; 61 nurses (91.0%) expected the application of virtual simulation technology in the teaching and training of other knowledges. Conclusion:As a new teaching form, virtual simulation technology can significantly improve the training effect and satisfaction, and provide reference for the development of relevant teaching and training.
