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 evaluate the changes of bronchial mucosa observed by fiberoptic bronchoscopy after bronchial arterial embolization(BAE)treatment.Methods A total of 176 patients,who received BAE at the First Affiliated Hospital of Guangzhou Medical University of China from May 2019 to March 2024,were enrolled in this study.The pre-BAE and post-BAE bronchial mucosa was checked by fiberoptic bronchoscopy.Results Of the 176 patients,fiberoptic bronchoscopy showed no abnormal findings in 143 and showed abnormal findings in 33.All the abnormal findings were mucosal congestion and oedema,in some cases coexisting vascular bulge was seen,but no manifestations of ischemia or necrosis of the bronchial mucosa could be found.In 22 patients,the preoperative and postoperative 7-day fiberoptic bronchoscopy revealed that both preoperative and postoperative examinations showed no obvious abnormalities of the bronchial mucosa in 13 patients,preoperative examination had abnormalities of the bronchial mucosa in 9 patients,postoperative examination showed no obvious abnormalities of the bronchial mucosa in 3 patients,and in one patient the postoperative degree of bronchial mucosal congestion and oedema was significantly improved when compared with its preoperative degree.Conclusion BAE does not cause ischemic necrosis or shedding of bronchial mucosa,and BAE can reduce the degree of bronchial mucosal congestion in some patients.

Objective To observe the effects of Bushen Huoxue Prescription on pressure-induced necroptosis in human nucleus pulposus cells and the expressions of RIPK1/RIPK3/MLKL pathway;To explore its potential mechanism in delaying intervertebral disc degeneration.Methods Human primary nucleus pulposus cells were cultured in vitro,and a model of nucleus pulposus cell degeneration was established using continuous load pressure method.After modeling,the nucleus pulposus cells were divided into model group,Bushen Huoxue Prescription group and inhibitor group,blank serum,Bushen Huoxue Prescription containing serum and necroptotic apoptosis inhibitor(Nec-1)intervention were administered,respectively.Normal group nucleus pulposus cells were cultured routinely.AO/EB fluorescence dual staining method was used for detecting cell apoptosis,flow cytometry was used to detect the necroptosis rate of nucleus pulposus cells,Western blot was used to detect the protein expressions of p-receptor interacting protein kinase(RIPK)1,p-RIPK3 and p-mixed lineage kinase domain like protein(MLKL),RT-qPCR was used to detect the mRNA expressions of RIPK1,RIPK3 and MLKL.Results Compared with the normal group,the model group showed more red fluorescence under AO/EB staining of nucleus pulposus cells,which were round and condensed,the necroptosis rate of nucleus pulposus cells increased(P<0.05),the protein expressions of p-RIPK1,p-RIPK3 and p-MLKL increased(P<0.05,P<0.01),while there was no significant difference in RIPK1 mRNA expression(P>0.05),and RIPK3 and MLKL mRNA expression increased(P<0.01).Compared with the model group,Bushen Huoxue Prescription group and the inhibitor group had less red condensed chromatin in the nucleus pulposus cells,Bushen Huoxue Prescription group had a lower rate of necroptosis(P<0.05),while the inhibitor group showed a decreasing trend in necroptosis rate(P>0.05),the protein expressions of p-RIPK1,p-RIPK3 and p-MLKL decreased in Bushen Huoxue Prescription group and the inhibitor group(P<0.05,P<0.01),while there was no significant difference in RIPK1 mRNA expression(P>0.05),and RIPK3 and MLKL mRNA expressions decreased(P<0.01).Conclusion Bushen Huoxue Prescription can alleviate pressure-induced damage to nucleus pulposus cells and inhibit necroptosis,thereby slowing the progression of intervertebral disc degeneration.Its mechanism may be related to the RIPK1/RIPK3/MLKL pathway mediated necroptosis.

Objective:To analyze the molecular characteristics of the virus in a local outbreak of dengue fever in Jiangsu province in 2023, and to provide a basis for the prevention and control of the outbreak.Methods:Serum samples were collected from suspected dengue patients in the acute phase of the outbreak for virus detection and serotyping by real-time fluorescence quantitative RT-PCR (RT-qPCR). Positive specimens were amplified with full-length genomic fragments and subjected to second-generation sequencing and related evolutionary analyses.Results:Four confirmed cases of dengue were found in Changzhou city, Jiangsu province, from October 18 to 21, 2023, with epidemiological association between the cases, which was recognized as a dengue outbreak. The serum RT-qPCR result of the four cases were all dengue type 1, and the whole genome sequences of three of the cases were obtained. The evolutionary tree of the E gene and the whole genome showed that the three sequences were located in the 3rd branch of the 1-I genotype, which is similar to the genotype 1-I. The genome-wide sequences of the E gene and the genome-wide evolution tree showed that the three sequences were located in the 3rd branch of the 1-I genotype, which is similar to the genome-wide genotype 1-Ⅰ. The E gene and the genome-wide evolutionary tree showed that all three sequences were located on branch 3 of genotype 1-Ⅰ, with high sequence similarity to the dengue virus epidemic strains in Guangdong and Yunnan provinces in 2023. Amino acid variant site analysis showed that there were 16 branch-specific amino acid site changes in the sequences of the three cases, among which the structural proteins, C protein and prM protein, had one variant site each, E protein had two, and the non-structural proteins had the largest number of NS5 variant sites (9).Conclusions:The local outbreak in Jiangsu was caused by dengue fever type 1 virus, with high nucleotide sequence similarity to strains from other regions of China, and amino acid site alterations.

Objective To study the physical and chemical stability of biapenem and parenteral nutrient solutions when they are used together through a Y-type infusion pathway,and to evaluate the rationality and feasibility of clinical compatibility.Methods Based on the actual clinical infusion rates of biapenem solution and parenteral nutrition solution in ICU,under room temperature and light conditions,simulate a Y-shaped pathway to mix biapenem solution and four types of parenteral nutrition solutions in three volume ratios(1∶1,2∶1,3∶1),and collect the compatible solutions at 0,1,2,4,and 6 hours,observing the appearance,pH value,osmolality,insoluble particles,Zeta potential,particle size and the change of biapenem content of the compatible solution,to investigate the potential interaction between them.Results Within 6 hours,the appearance,pH value,osmotic pressure,insoluble particles,particle size,and Zeta potential did not significantly change.Compared with zero time,the content of the biapenem fluctuated between 93.68%and 100.86%,and there was no impurity peak interference in the chromatogram.Conclusion The physico-chemical properties of biapenem were stable within 6 hours under the condition of room temperature and no light exposure through Y-type infusion pathway and parenteral nutrient solutions.

Objective To explore the impact of suture configuration and fixation type on the biome-chanical strength of rotator cuff repair,using a factorial design study.Methods Sixteen fresh-frozen porcine shoulder samples were randomized into an anchorless double-row suture bridge transosseous su-tures(DS)group,an anchored double-row suture bridge transosseous-equivalent(DE)group,an an-chorless X-BOX construct transosseous sutures(XS)group,and an anchored X-BOX construct transos-seous-equivalent(XE)group,each of four,according to suture configuration(double-row suture bridge,traditional X-BOX construct)and fixation type(suture anchors,transosseous sutures).Then,their fatigue resistance(first-cycle excursion,gap length difference ratio,and the percentage of ex-posed footprints)and the failure strength(the maximum failure load and the re-tear type)were mea-sured using a biomechanical material testing machine.Results Different suture configurations affected failure strength(F=39.559,P<0.001),with the double-row suture bridge groups(693.07±58.35 N,746.76±138.57 N)showing significantly higher failure strength,compared to the traditional X-BOX groups(462.90±18.91 N,421.43±90.76 N).However,the fixation type did not significantly im-pact failure strength(F=1.161,P=0.302).Moreover,the suture configuration influenced the gap differ-ence ratio(F=7.781,P=0.016),but had no significant correlation with other fatigue resistance indica-tors(P>0.05).Meanwhile,failure strength and fatigue resistance were not correlated with fixation type,and the interaction between suture and fixation type(P>0.05).The incidence of failure types for the four suture configurations was as follows:Type I tendon tear:XS>XE>DS=DE;type II tendon tear:DS>XE>XS=DE;fixing material-related failure:DE>DS=XE=XS.Conclusion The failure strength and gap formation ratio in rotator cuff repair under fatigue loading are influenced by suture configuration,whereas no significant association has been observed with respect to fixation method,whether using transosseous sutures or suture anchors.

As the incidence of autism rises annually,its unknown pathogenesis makes it challenging to treat the varied repetitive and stereotyped behaviors that characterize its core symptoms.The striatum is an important brain region for the control of locomotor behaviors,featuring a unique mosaic structure,complex neural origin,and finely regulated developmental process that is highly susceptible to genetic and environmental influences.Both clinical and basic studies have indicated that abnormal development of the striatal nuclei may contribute to the pathogenesis of these repetitive stereotyped behaviors in autism.Clinical imaging data have primarily identified gross anatomical variations in the stratum(e.g.,its general outline),but lack the resolution necessary to detect the cellular and subcellular alterations within the region.By introducing the abnormalities in the spatiotemporal development of the striatum and their links to the characteristic behaviors of autism,this review aims to advance our understanding of the role of the striatum in autism pathogenesis and to inform future animal studies and clinical research.

Objective:To investigate the G/P genotypes of group A rotavirus（RVA）in the 2023 sentinel surveillance in Jiangsu Province，and to conduct a molecular characterization analysis of the whole-genome sequences of four G9P［4］genotype RVA strains identified during surveillance.Methods:A total of 212 RVA-positive specimens collected from the surveillance system in 2023 were subjected to G/P genotyping using multiplex nested RT-PCR. Whole-genome sequencing was performed on six G9P［4］strains. The resulting complete genome sequences were preliminarily genotyped using BLAST，followed by comprehensive molecular characterization analyses utilizing BioEdit 7.0.5，MAFFT，MEGA 7.0，and iTOL software.Results:The overall RVA positivity rate was 6.22%. The predominant G/P combination in both outpatient and inpatient settings was G8P［8］. Among the six G9P［4］strains，four were successfully sequenced. All four exhibited the genotype constellation G9-P［4］-I2-R2-C2-M2-A2-N1-T2-E2-H2. While the NSP2 gene belonged to the N1 genotype，all other genes corresponded to the DS-1-like genogroup. Phylogenetically，the four Jiangsu G9P［4］strains clustered within Lineage V of the VP7 gene and formed a distinct minor subclade within the N1 branch of the NSP2 gene. Unique amino acid substitutions were identified at multiple VP7 neutralization antigenic epitope sites when compared to vaccine strains.Conclusions:The predominant circulating RVA strain in Jiangsu province during 2023 was G8P［8］. Concurrently，the relatively uncommon G9P［4］-N1 strain was detected. This strain exhibited significant amino acid differences at key epitopes compared to vaccine strains. Enhancing the proportion of whole-genome sequencing in RVA surveillance is warranted to obtain more detailed genetic information，thereby providing crucial data to support future vaccine development and optimization strategies.
