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 investigate the management of granulation tissue during surgery for infected congenital preauricular fistula and to assess the surgical outcomes. Methods:To summarize the surgical methods and the treatment of granulation methods in 140 cases of congenital preauricular fistula during the period of infection treated in our department from January 2018 to September 2022. The study divided patients into an observation group （79 patients） undergoing fistulectomy without granulation treatment, and a control group （61 patients） where fistulectomy and granulation resection were performed concurrently.. After six months of follow-up, the wound healing, recurrence rates, and the aesthetic assessment of granulation healing were evaluated using the Stony Brook Scar Evaluation Scale（SBSES）. Results:The two surgical approaches were applied to a total of 140 patients with infected congenital preauricular fistula. There was no statistical difference in wound healing and recurrence rates between the observation group and the control group. However, the observation group exhibited smaller scars. Conclusion:In cases of infected congenital preauricular fistula, surgical removal without excising granulation tissue is feasible, leading to effective healing and lesser scar formation.

After 12 weeks of treatment， the total effective rate of the comprehensive curative effect of diabetic retinopathy in the treatment group （61.0%， 189/310） was better than that in the control group （44.1%， 45/102）， and the difference was statistically significant （χ²=8.880， P<0.01）. The total effective rate of TCM syndromes in the treatment group （88.4%， 259/293） was better than that in the control group （69.9%， 65/93）， and the difference was statistically significant （χ²=17.927， P<0.01）. The disappearance rate of dry eyes （χ²=8.305）， dull complexion （χ²=4.053）， lassitude （χ²=10.267）， shortness of breath （χ²=8.494）， and dry stool （χ²=8.657） in the treatment group was higher than that in the control group， and the difference between the groups was statistically significant （P<0.05， P<0.01）. In terms of improving corrected visual acuity （χ²=8.382）， fundus changes （χ²=6.026） ， the treatment group was significantly better than the control group （P<0.05）. During the trial， the incidence of adverse events in the treatment group and the control group was 1.3% and 2.9%， respectively. There was no significant difference between the two groups. In addition， there were no serious adverse events and adverse events leading to withdrawal in both groups. ConclusionTongluo Mingmu capsules can improve the comprehensive curative effect of diabetic retinopathy and enhance the efficacy of TCM syndromes， visual acuity， fundus changes， and fundus fluorescein angiography， with great safety. Therefore， it can provide a new alternative therapeutic drug for patients with diabetic retinopathy.

Cough variant asthma （CVA） is a chronic respiratory disease with cough as its main symptom. The occurrence of CVA is closely related to non-specific airway inflammation， and its pathogenesis involves environmental， genetic， immune， and other factors. In recent years， the advantages of traditional Chinese medicine （TCM） in the treatment of CVA have attracted the attention of experts and scholars in China and abroad， especially its prominent role in regulating immune balance， relieving cough symptoms in CVA patients， and reducing recurrence. T Helper cells 1 （Th1）， T helper cells 2 （Th2）， T helper cells 17 （Th17）， and regulatory T cells （Treg） are derived from CD4⁺ T cells. Immune imbalance of Th1/Th2 and Th17/Treg is a new hotspot in the pathogenesis of CVA and a potential key target in the treatment of CVA by TCM. Th cell subsets are in dynamic balance under physiological conditions， maintaining respiratory immune homeostasis in which pro-inflammatory cytokines and anti-inflammatory cytokines are balanced. Immature helper T cells （Th0） can be differentiated into Th1， Th2， Th17， Treg， and other cell subsets due to cytokine types in the microenvironment in the stage of CVA maturation. The proliferation of Th2 cells leads to eosinophilic airway inflammation. Excessive differentiation of Th17 cells induces neutrophil airway inflammation. Th1/Th2 and Th17/Treg cells are mutually restricted in number and function， and the immune imbalance of Th1/Th2 and Th17/Treg is easy to aggravate the generation of inflammatory response. Restoring immune balance is particularly important for the airway anti-inflammatory therapy of CVA. In this paper， the imbalance of Th1/Th2 and Th17/Treg and the pathogenesis of CVA were systematically expounded. Meanwhile， the latest research on the regulation of immune imbalance by TCM compound， single TCM， and its effective ingredients in the treatment of CVA was reviewed. It provides ideas and references for revealing the scientific connotation of TCM regulating immune balance therapy of CVA， as well as the development of clinical treatment and basic research of CVA.

ObjectiveTo determine the drug sensitivity and molecular typing characteristics of Klebsiella pneumoniae isolated from meat and diarrhea samples in a local area. MethodsSeventy-one strains of K.pneumoniae were isolated from 118 meat food （chicken and pork） randomly sampled in the markets in Jinshan District， Shanghai， 2020‒2021， and 1 499 diarrhea samples from outpatient diarrhoea patients in hospitals in the same district. Then drug susceptibility testing was conducted by micro-broth dilution method， and sequence identity was determined by pulsed field gel electrophoresis（PFGE）. ResultsThe overall detection rate of K.pneumoniae in meat was 11.86% （14/118）， with detection rate 20.93% （9/43） in chicken and 6.67% （5/75） in pork. The difference in detection between meats was statistically significant （χ²=5.317，P<0.05）. The detection rate of K.pneumoniae in diarrhea samples was 3.80% （57/1 499）. Furthermore， the isolated strains showed the highest resistance to ampicillin at 76.06%. The multi-drug resistant strains included 5 of human origin （8.77%） and 2 of foodborne origin （14.28%）. Additionally， 1 foodborne imipenem-resistant strain was detected. A total of 71 strains of K.pneumoniae were found to have 70 banding types， with similarity ranging from 39.4% to 100%， suggesting genetic diversity. ConclusionK.pneumoniae isolated from foodborne and diarrhea samples showed multi-drug resistance in Jinshan District， . with scattered PFGE banding patterns. It is recommended to strengthen the monitoring of this pathogen in the population and animal food， and be alert to the emerging multi-drug resistant strains and risk of food chain transmission.

Objective To explore the health promotion behaviors among patients with pulmonary tuberculosis(TB),and to analyze its relationship with health locus of control,in order to provide scientific references for improving TB patients'health-promotion behaviors in clinical nursing care.Methods The interpretive sequence mixed method design was utilized.A convenient sampling was used to enroll 300 TB patients from 2 TB specialized tertiary hospitals in Xi'an as research subjects from January to April 2023.General information questionnaire,Health promoting lifestyle profile-Ⅱ,and Multidimensional health locus of control scale were used to collect data,and single-factor analysis and multiple linear regression analysis were conducted.Purposeful sampling was used to select 11 TB patients for a semi-structured interview,and the Colaizzi 7-step method was used to extract themes.Results In the quantitative study,the total score of health promoting behaviors in 294 TB patients was(110.26±15.74).Patients'intemal health locus of control,chance health locus of control,and occupational status significantly influenced their health-promotion behaviors(P＜0.05).In the qualitative study,4 themes were extracted,including awakening self-awareness of health,the desire to establish a normal life,the distress of multiple uncertainties,and the immediate effect of authoritative guidance.The qualitative and quantitative studies complemented each other and further verified the relationship between health promotion behaviors and health locus of control of TB patients.Conclusion The level of health-promotion behaviors in TB patients needs to be further improved.Nurses need to take systematic health education as an opportunity by the catalytic effect of individual health awareness,to improve their internal locus of control,reduce their opportunity control tendency due to multiple uncertainties,with the ultimate purpose of helping TB patients form and maintain health promotion behaviors.

Astrocytes are important nerve cells in the central nervous system （CNS）， which mainly play a key role in nutrition and support. Astrocytes and neurons undergo close energy coupling and substance coupling， which are closely related and interact with each other. In recent years， many studies have shown that the astrocyte-neuron coupling imbalance plays a central role in the occurrence and progression of Alzheimer's disease （AD） and serves as an important therapeutic target receiving increasing attention. According to traditional Chinese medicine （TCM） theory， the main pathogenesis of AD is kidney deficiency and marrow inadequacy， and in clinical medication， kidney-tonifying and marrow-filling TCM prescriptions are often employed with satisfactory results achieved. As reported， many kidney-tonifying and marrow-filling prescriptions exhibit regulatory and protective effects on the imbalance of astrocyte-neuron coupling， suggesting that the effect of kidney-tonifying and marrow-filling prescriptions in treating AD may have some internal relationship with its regulation of the imbalance of astrocyte-neuron coupling. This article reviewed the underlying internal relationship between the imbalance of astrocyte-neuron coupling and the pathogenesis of kidney deficiency and marrow inadequacy in AD and the research progress in the intervention mechanism of TCM for tonifying the kidney and filling the marrow.

ObjectiveTo explore the mechanism of Dihuang Yinzi in improving astrocyte injury and glycolysis in Alzheimer's disease （AD） mice via regulating the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway， thereby improving the cognitive function of AD mice. MethodForty male APP/PS1 transgenic mice aged four months were randomly divided into a model group and a model + Dihuang Yinzi （0.25 g·kg^-1） group， with 20 mice in each group. Forty C57BL/6J mice with the same background and same age were randomly divided into a control group and a control + Dihuang Yinzi （0.25 g·kg^-1） group， with 20 mice in each group. The mice in the control + Dihuang Yinzi group and the model + Dihuang Yinzi group were administered with Dihuang Yinzi by gavage， and those in the control group and the model group received an equal volume of sterilized normal saline， once a day for 150 days. Morris water maze test was performed to test the ability of navigation and space exploration of mice. The protein expression of p-PI3K， PI3K， p-Akt， Akt， phosphofructokinase-1 （PFK-1）， and aldehyde dehydrogenase 3 family member B2 （ALDH3B2） in mouse brain tissues was measured by Western blot. An immunofluorescence assay was performed to detect astrocyte morphology and the expression level of ALDH3B2. ResultAs compared with the control group， the model group showed prolonged escape latency during the 2^nd to 5^th days of the location-based navigation （P<0.05， P<0.01）， reduced number of times crossing the target area of the platform， shortened residence time in the target quadrant （P<0.05， P<0.01）， prolonged residence time in the opposite quadrant （P<0.05）， increased surface area of the cell body and total length of cell protrusions of astrocytes （P<0.05， P<0.01）， and down-regulated protein expression of p-PI3K， p-Akt， ALDH3B2， and PFK-1 （P<0.01）， while the above experimental indexes were not significantly different in the control + Dihuang Yinzi group. Compared with the model group， the model + Dihuang Yinzi group showed shortened escape latency of APP/PS1 mice during the 2^nd to 5^th days of the location-based navigation （P<0.05， P<0.01）， increased number of times crossing the platform， prolonged target quadrant residence time （P<0.05， P<0.01）， shortened residence time in the opposite quadrant （P<0.05）， reduced surface area of the cell body and total length of cell protrusions of astrocytes （P<0.05）， and up-regulated protein expression of p-PI3K， p-Akt， ALDH3B2， and PFK-1 （P<0.01）. ConclusionDihuang Yinzi can improve the learning and memory ability of AD mice by activating the PI3K/Akt signaling pathway and up-regulating the protein expression of PFK-1 and ALDH3B2 to protect against astrocyte injury in brain tissues and improve glycolysis.
