The development of traditional Chinese medicine (TCM) diagnosis and treatment has undergone multiple paradigms, evolving from sporadic experiential practices to systematic approaches in syndrome differentiation and treatment and further integration of disease and syndrome frameworks. TCM is a vital component of the medical system, valued alongside Western medicine. Treatment based on syndrome differentiation embodies both personalized treatment and holistic approaches; however, the inconsistency and lack of stability in syndrome differentiation limit clinical efficacy. The existing integration of diseases and syndromes primarily relies on patchwork and embedded systems, where the full advantages of synergy between Chinese and Western medicine are not fully realized. Recently, driven by the development of diagnosis and treatment concepts and advances in analytical technology, Western medicine has been rapidly transforming from a traditional biological model to a precision medicine model. TCM faces a similar need to progress beyond traditional syndrome differentiation and disease-syndrome integration toward a more precise diagnosis and treatment paradigm. Unlike the micro-level precision trend of Western medicine, precision diagnosis and treatment in TCM is primarily reflected in data-driven applications that incorporate information at various levels, including precise syndrome differentiation, medication, disease management, and efficacy evaluation. The current priority is to accelerate the development of TCM precision diagnosis and treatment technology platforms and advance discipline construction in this area.

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 expression of Toll-like receptor 9 (TLR9) in B cells in the peripheral blood of patients with allergic rhinitis (AR), allergic asthma (AA), AR combined with AA (ARA) and the blood or lung tissue of sensitized mice, as well as the effect of allergens on its expression. 【Methods】 A total of 100 volunteers from The First Affiliated Hospital of Jinzhou Medical University were recruited for outpatient and acute inpatient attacks, consisting of 19 healthy people (HC) with negative prick test result, 40 AR patients, 26 AA patients, and 15 ARA patients with positive prick test result. The expression of TLR9 in the peripheral blood B cells of the patients before and after stimulation by house dust mite allergen extract (HDME), Artemisia sieversiana wild allergen extract (ASWE), and Platanus pollen allergen extract (PPE) was detected by flow cytometry. AR and AA sensitization models were established in WT mice and FcεRI-KO mice to detect the effects of allergens and FcεRI on the expression of TLR9 in B cells. 【Results】 The expression and mean fluorescence intensity (MFI) of TLR9 in peripheral blood B cells of unstimulated AR, AA and ARA patients were higher than those of HC. After allergen stimulation, the expression of TLR9 and its MFI in blood B cells of AR and AA patients increased (P<0.05). In WT mice and FcεRI-KO mice, compared with NS control mice, MFI was increased in almost each group. Compared with the NS control group, there was no significant difference in the expression of TLR9⁺ in B cells in the lung tissues of AA mice with FcεRI-KO after allergen challenge, but their MFI increased. FcεRI-KO mice had lower TLR9⁺ MFI in B cells after allergen challenge compared with WT mice. 【Conclusion】 TLR9 in B cells may be involved in the occurrence of AR and AA, and detecting the expression of TLR9 in B cells may be a new direction for the diagnosis of AR and AA.

Objective To investigate the efficacy and safety of Cyberknife in the treatment of elderly patients(aged≥75 years)with early stage non-small cell lung cancer(NSCLC),and to compare the results with those of patients aged<75 years.Methods We retrospectively analyzed 75 patients with early(T1-2N0M0)NSCLC admitted to the 960th Hospital of Jinan People's Liberation Army from January 2013 to October 2019.There were 32(42.7%)patients aged<75 years,and 43(57.3%)patients aged≥75 years.All patients were treated with 45-66Gy/3-8F,60%-85%isodose line as the prescription dose to cover planning target volume(PTV),and irradiation once a day and five times a week.The clinical efficacy,survival status and radiotherapy toxicity of the two groups were compared,and the factors affecting the efficacy of elderly patients were analyzed.Results The disease control rates of patients aged<75 and≥75 years were 96.9%and 93.0%,respectively(P>0.05).The 5-year local control rate(LC),progression-free survival(PFS)and cancer-specific survival(CSS)were 70.9%and 85.4%,58.5%and 54.4%,and 70.4%and 64.5%,respectively(P>0.05).However,the overall survival(OS)of patients aged≥75 years was significantly lower than that of patients aged<75 years,and the 5-year OS was 49.2%and 68.2%,respectively(P<0.05).There was no significant difference in the treatment complications between the two groups(P>0.05).Multivariate analysis showed that biologic effective dose(BED)was an independent factor affecting OS in patients aged≥75 years.Conclusion Stereotactic body radiotherapy with cyberknife is a safe and effective treatment for elderly patients with early stage NSCLC who are not suitable for surgery.

Aminopeptidase A (Pep A) is a metal-dependent enzyme that specifically hydrolyze peptides with the N-terminal amino acids glutamic acid (Glu) and aspartic acid (Asp). A possible application of PepA is the hydrolysis of Glu/Asp-rich food proteins such as wheat gluten and casein, increasing the flavor and solubility of food protein. In the present study, the gene encoding a Pep A from Lactococcus lactis ssp. lactis IL1403 was synthesized and introduced into Pichia pastoris GS115 (His4). Lc-Pep A was successfully expressed and secreted to the culture medium, followed by identification and purification to homogeneity. Characteristics study demonstrated that Lc-Pep A could specifically hydrolyze the substrates Glu-pNA and Asp-pNA with similar catalytic activity, and this was further confirmed by the kinetics parameters measured. Additionally, Lc-Pep A showed a broad thermostability and pH stability with an optimum temperature of 60 ℃ and an optimum pH of 8.0. The enzyme activity of Lc-Pep A was activated by metal ions Co²⁺, Mn²⁺, and Zn²⁺ but was strongly inhibited by Ni²⁺and Cu²⁺. The routine proteinase inhibitor had no effect on the activity of Lc-Pep A. However, Lc-Pep A was strongly inhibited by the metallopeptidase inhibitor, EDTA, and disulfide bond-reducing agents. The study may facilitate production and application of Lc-Pep A.

Objective To investigate the correlation between early serum β2-microglobulin (β2-MG) and cystatin-C (Cys-C) levels and post-stroke depression (PSD) in patients with acute cerebral infarction and their clinical significance. Methods Patients with acute cerebral infarction within 72 hours of the first onset were consecutively collected,and the diagnosis met the diagnostic criteria of the Chinese Guidelines for the Diagnosis and Treatment of Acute Ischemic Stroke 2018,all confirmed by head MRI DWI,with reference to the diagnostic criteria of PSD and the 24-item version of the Hamilton Depression Scale-24 (HAMD-24) scores were included in the patients. Scores≥8 were included in the study group (PSD group),and the PSD group was further divided into two subgroups,mild and moderate-severe,according to the HAMD score. Laboratory indicators such as serum β2-MG,Cys-C and biochemistry and clinical data were collected on admission. Results 64 of 174 patients with acute cerebral infarction were diagnosed with PSD,with an incidence of 37%. Compared with the control group,there were statistical differences in age,hypertension,high-density lipoprotein cholesterol (HDL-C),serum creatinine (Scr),β2-MG and Cys-C in the study group,and the results of multifactorial logistic regression analysis showed that age,β2-MG and Cys-C might be the most important factors. β2-MG and Cys-C may be independent risk factors for the occurrence of PSD;meanwhile,the levels of β2-MG and Cys-C were found to be positively correlated with the severity of PSD (P<0.01). The analysis of the role of serum β2-MG and Cys-C in the diagnosis of PSD by applying ROC curves showed that the AUC of β2-MG was 0.781,with a sensitivity of 0.672 and specificity of 0.909;the AUC of Cys-C was 0.785,with a sensitivity of 0.828 and specificity of 0.736;the AUC of the combined diagnosis was 0.815,with a sensitivity of 0.656 and specificity of 0.909.Conclusion Age,serum β2-MG and Cys-C may be independent risk factors for the occurrence of PSD,and serum β2-MG and Cys-C are associated with the severity of PSD;β2-MG and Cys-C may have some diagnostic value for the occurrence of PSD,and the combined diagnostic value of the two is higher.
