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.

As one of the chronic diseases with high incidence in contemporary society, cervical spondylosis has increasing patient groups who gradually present a low age, and it seriously affects social and public health. Although modern medicine has made great progress in the pathological research and clinical treatment of cervical spondylosis, patients still face gastrointestinal side effects of nonsteroidal anti-inflammatory drugs(NSAIDs), neck pain, limited mobility, upper limb numbness, and other symptoms after conservative or surgical treatment. In the theory of traditional Chinese medicine(TCM), cervical spondylosis belongs to the categories of "Bi syndrome" "stiff neck" "stiff Bi", etc. With the change of the times, the change of lifestyle, and the application of western medicine treatment, the etiology and pathogenesis of TCM in cervical spondylosis also show new characteristics. In terms of etiology and pathogenesis, it involves the invasion of wind, cold, and dampness, long-term strain, liver and kidney deficiency, Qi and blood stasis, which are associated with factors such as cervical degeneration, muscle tension and spasm, intervertebral disc herniation, and nerve root compression in modern medicine. In terms of the evolution of pathogenesis, in the early stage, wind, cold, and dampness, were more common in Xuanfu, resulting in unfavorable muscles and bones, poor flow of Qi and blood, and cervical spondylosis and radiculopathy. Medium-term phlegm stasis and internal knots, sluggish muscles and veins, and long-term weathering and fire are more likely to occur in the vertebral artery and sympathetic radiculopathy. In the later stage, the positive Qi is depleted; the true Yin is damaged, and the viscera Qi and blood are deficient, which is most common in cervical myelopathy. The strategy of treating cervical spondylosis with TCM classic formulas applies Gegen Decoction, Wutou Decoction, Qianghuo Shengshi Decoction, Mahuang Jiazhu Decoction to patients with wind, cold, and dampness. Patients with phlegm dampness and blood stasis are treated with Huoxue Xiaoling Dan, Jinlingzi Powder, Siwu Decoction, Banxia Baizhu Tianma Decoction, Shuanghe Decoction, etc. For those patients with liver, spleen, and kidney deficiency, Huangqi Guizhi Wuwu Decoction, Tianma Gouteng Decoction, Guishao Dihuang Pills, Shenling Baizhu Powder, and Lizhong Decoction are used to invigorate the spleen, nourish Qi and blood, and tonify liver and kidney. In clinical practice, the authors advocate a safe and effective treatment plan of classic formulas based on deficiency and excess, the integration of formulas and syndromes, and the combination of modern research results, so as to relieve symptoms, reduce recurrence, and reduce medical burden.

OBJECTIVES: To investigate the association between maternal depressive symptoms and adolescent suicidal ideation, and to examine the chain mediating roles of childhood trauma and ineffectiveness. METHODS: A cross-sectional online survey was administered by school psychologists to 4 157 mother-adolescent pairs from middle schools in Shanghai and Henan, China. Measures included the Center for Epidemiological Studies Depression Scale, the Childhood Trauma Questionnaire, and the Children's Depression Inventory. Using Bootstrap method to examine the chain mediating effect of childhood trauma and ineffectiveness on the relationship between maternal depression symptoms and adolescent suicidal ideation. RESULTS: The prevalence of maternal depressive symptoms was 17.68% (735/4 157); among adolescents, the prevalence of depressive symptoms was 15.49% (644/4 157), and suicidal ideation was 28.19% (1 172/4 157). Adolescent depressive symptoms and suicidal ideation were positively correlated with maternal depressive symptoms, childhood trauma, and ineffectiveness (all P<0.01). Childhood trauma significantly mediated the association between maternal and adolescent depressive symptoms (95%CI: 0.046 9-0.077 2). The chain mediation of childhood trauma and ineffectiveness in the association between maternal depressive symptoms and adolescent suicidal ideation was also significant (95%CI: 0.000 7-0.001 3). CONCLUSIONS Higher maternal depressive symptom levels are associated with a greater likelihood of adolescents' exposure to childhood trauma, which increases adolescents' ineffectiveness and, in turn, is associated with suicidal ideation. This chain effect has important implications for social interventions targeting adolescent depression.

OBJECTIVE: To investigate the effect of piperlongumine(PL) on the proliferation and ferroptosis of human adriamycin-resistant chronic myeloid leukemia K562/ADR cells, and to explore its possible molecular mechanism. METHODS: CCK-8 assay was used to detect the effect of PL on the survival rate of K562/ADR cells and to screen the appropriate drug concentration. After K562/ADR cells were treated with low, medium and high concentrations of PL(2, 4, and 6 μmol/L), EdU proliferation assay and plate colony formation assay were used to detect cell proliferation and colony formation ability. CCK-8 assay was used to detect the effects of different inhibitors (Fer-1, Z-VAD, Nec-1) combined with PL on cell proliferation. The intracellular Fe²⁺, ROS, malondialdehyde(MDA) and glutathine(GSH) contents were respectively detected by iron ion colorimetry, DCFH-DA fluorescent probe, MDA and GSH kits. RT-qPCR and Western blot were respectively used to detect the expression level of GPX4 mRNA and protein in cells. Bioinformatics websites predicted miRNA that could target and regulate GPX4 . RT-qPCR was used to detect the effects of different concentrations of PL on the expression levels of the predicted miRNA. Dual luciferase gene reporter assay was used to verify the targeting relationship between miR-214-3p and GPX4 . After treating cells with PL or PL+miR-214-3p inhibitor, the Fe²⁺, ROS, MDA, GSH centents and GPX4 protein expression levels in cells were detected. RESULTS: PL inhibited K562/ADR cell proliferation in a concentration-dependent manner（r =0.979）. Compared with the blank control group, the survival rate, EdU positive cells rate in low, medium and high concentration PL groups were significantly decreased (P < 0.01). Compared with the PL group alone, the survival rate of cells in the Z-VAD+PL group was increased slightly (P < 0.05). The cell survival rate was significantly increased in medium or high concentration PL+Fer-1 group (P < 0.01). Compared with blank control group, ROS expression level in low concentration PL group was slightly increased (P < 0.05), and GSH content was slightly decreased (P < 0.05). In medium and high concentration PL groups, the contents of Fe²⁺, ROS and MDA were significantly increased (P < 0.01), while the contents of GSH, expression of GPX4 mRNA and protein were significantly decreased(P < 0.01). Bioinformatics prediction and double luciferase reporter gene experiment confirmed the targeting relationship between GPX4 and miR-214-3p. Compared with the blank control group, the expression level of miR-214-3p in cells of medium and high concentration PL groups was significantly increased (P < 0.01). Compared with PL group alone, the intracellular Fe²⁺, ROS and MDA contents in PL+miR-214-3p inhibitor group were all decreased (P < 0.01), while GSH content and GPX4 protein expression levels were significantly increased (P < 0.01). CONCLUSION Medium and high concentrations of PL can inhibit the proliferation of K562/ADR cells by inducing ferroptosis, which is related to the regulation of miR-214-3p pathway.

OBJECTIVE: To reveal the effects and potential mechanisms by which synaptic vesicle glycoprotein 2A (SV2A) influences the distribution of amyloid precursor protein (APP) in the trans-Golgi network (TGN), endolysosomal system, and cell membranes and to reveal the effects of SV2A on APP amyloid degradation. METHODS: Colocalization analysis of APP with specific tagged proteins in the TGN, ensolysosomal system, and cell membrane was performed to explore the effects of SV2A on the intracellular transport of APP. APP, β-site amyloid precursor protein cleaving enzyme 1 (BACE1) expressions, and APP cleavage products levels were investigated to observe the effects of SV2A on APP amyloidogenic processing. RESULTS: APP localization was reduced in the TGN, early endosomes, late endosomes, and lysosomes, whereas it was increased in the recycling endosomes and cell membrane of SV2A-overexpressed neurons. Moreover, Arl5b (ADP-ribosylation factor 5b), a protein responsible for transporting APP from the TGN to early endosomes, was upregulated by SV2A. SV2A overexpression also decreased APP transport from the cell membrane to early endosomes by downregulating APP endocytosis. In addition, products of APP amyloid degradation, including sAPPβ, Aβ _1-42, and Aβ _1-40, were decreased in SV2A-overexpressed cells. CONCLUSION These results demonstrated that SV2A promotes APP transport from the TGN to early endosomes by upregulating Arl5b and promoting APP transport from early endosomes to recycling endosomes-cell membrane pathway, which slows APP amyloid degradation.

Objective To establish a stable rat model of non-obese polycystic ovary syndrome(PCOS)with clinical characteristics.Methods Dehydroepiandrosterone(DHEA)was used to establish a PCOS rat model by subcutaneous injection.Three-week-old female SD rats were divided into a normal group,6 mg/kg DHEA model group,and 60 mg/kg DHEA model group.The model groups were subcutaneously injected with the corresponding dose of DHEA daily,while the normal group was subcutaneously injected with glycerol daily for 21 consecutive days.The model was evaluated with ovarian histopathology as the gold standard to determine the optimal dosage of DHEA to induce a PCOS rat model.On this basis,the optimal DHEA modeling dose was selected,and stop and continue modeling groups were set up to observe the model for 28 days and evaluate its maintenance.The stop modeling group was no longer given DHEA,and the continued modeling group was subcutaneously injected with 60 mg/kg DHEA every 48 h.The evaluation indicators included body mass,estrous cycle,fasting blood glucose,serum insulin,histopathologic morphology of the ovaries,and serum sex hormone levels.Results(1)Compared with the normal group,the 6 mg/kg and 60 mg/kg DHEA model groups showed no significant difference in body mass,and their estrous cycles were irregular.There were more cystically dilated large follicles in the ovaries;fewer mature follicles;reduced layers of granulosa cells,which were arranged in a sparse and disorganized manner;and fewer lutea in the 6 mg/kg and 60 mg/kg DHEA model groups than the normal group.Furthermore,serum T and E2 levels were significantly higher in the 60 mg/kg DHEA model group(P＜0.05)than the normal group.(2)The stop modeling group(A2 group)resumed regular estrous cycles after 2 weeks,various growth follicles and corpora lutea were observed in the ovarian tissues,the number of cystic follicles was reduced,the number of granulosa cell layers increased,mature follicles were visible,oocyte morphology was locally intact,and the levels of E2 and AMH were reduced compared with the normal group(A1 group)(P＜0.05).(3)The continue model group(B2 group)was in the late stage of estrous cycle for a long period,and there were more large follicles with cystic dilatation,fewer mature follicles,fewer layers of granulosa cells with a sparse and disordered arrangement,and significantly fewer corpus lutea in the ovaries compared with the normal group(B1 group).The levels of serum LH,LH/FSH,and T were elevated(P＜0.05).Conclusions Subcutaneous injection of 60 mg/kg DHEA for 21 consecutive days can be used to successfully construct a non-obese PCOS rat model that possesses clinical characteristics.Subcutaneous injection of 60 mg/kg DHEA every 48 hours maintains the stability of the model.

Objective:To analyze the efficacy and safety of low-dose azacitidine in the treatment of senile myelodys-plastic syndromes(MDS).Methods:A total of 92 elderly MDS patients who were initially diagnosed in the Huaibei Miners General Hospital and the Affiliated Hospital of Xuzhou Medical University from January 2018 to June 2022 were randomly divided into the observation group and the control group with 46 patients in each group.The observation group received a low dose of azacitidine 100 mg/d,dl-7,28 days as a course of treatment,6 courses in total,and the control group received a standard dose of azacitidine 75 mg(m2·d),d1-7,28 days as a course of treatment,a total of 6 courses of treatment.The clinical efficacy,overall survival(OS)and adverse reactions of the two groups of patients were observed.Results:There was no statistically significant difference in the clinical data between the two groups(P＞0.05).After treatment,the hemoglobin and platelet levels of the two groups of patients were significantly higher than before treatment in each group(P＜0.05).There was no statistically significant difference in leukocyte,hemoglobin and platelet levels between patients in the observation group and control group(P＞0.05).The number of cases with complete remission,partial remission,hematological remission,disease stabilization and disease progression in the observation group were 4,10,22,6 and 4,respectively,with a total effective rate of 78.26％.The numbers of cases with complete remission,partial remission,hematological remission,disease stabilization and disease progression in control group were 8,12,18,4 and 4,respectively,with a total effective rate of 82.61％.The total effective rate of patients in the observation group was slightly lower than that of the control group(x2=0.457,P=0.254).There was no significant difference between the two treatment schemes in the treatment of patients with blood transfusion dependence and patients with low risk,medium risk and high risk(P＞0.05).It takes 4 and 6 courses of treatment to achieve the best treatment response in the control group and observation group respectively.There was no significant difference in OS between the two groups(P＞0.05).In the observation group,there were 4,6 and 2 cases of infection,Ⅲ-Ⅳ degree myelosuppression and gastrointestinal reaction,respectively,with the incidence rate of adverse events being 26.09％.In the control group,there were 6,16 and 6 cases of infection,Ⅲ-Ⅳ degree myelosuppression and gastrointestinal reaction,respectively,with the adverse event rate was 60.87％.The incidence of adverse events in the control group was significantly higher than that in the observation group(x2=7.095,P=0.036).Conclusion:Elderly patients with MDS have poor tolerance to chemotherapy.Reducing azacitidine in the treatment of elderly MDS patients shows good efficacy and safety.

AIM To investigate the clinical effects of Lingxian Tongluo Capsules combined with Wentong Acupuncture Method on patients with lumbar disc herniation.METHODS One hundred and four patients were randomly assigned into control group(52 cases)for 30-day intervention of both Wentong Acupuncture Method and conventional treatment,and observation group(52 cases)for 30-day intervention of Lingxian Tongluo Capsules,Wentong Acupuncture Method and conventional treatment.The changes in clinical effects,TCM syndrome scores,lumbar function indices(ODI index score,JOA score),VAS score,inflammatory factors(TNF-α,IL-1β,IL-6),hemorheological indices(plasma viscosity,whole blood high-shear viscosity,whole blood low-shear viscosity)and incidence of adverse reactions were detected.RESULTS The observation group demonstrated higher total effective rate than the control group(P＜0.05).After the treatment,the two groups displayed decreased TCM syndrome scores,ODI index score,VAS score,inflammatory factors and hemorheological indices(P＜0.05),and increased JOA score(P＜0.05),especially for the observation group(P＜0.05).No significant difference in incidence of adverse reactions was found between the two groups(P＞0.05).CONCLUSION For the patients with lumbar disc herniation,Lingxian Tongluo Capsules combined with Wentong Acupuncture Method can safely and effectively relieve clinical symptoms,promote lumbar function recovery,reduce pain degree,alleviate inflammatory responses,and improve hemorheology.

Background:Recurrence after stone removal is common in patients with choledocholithiasis.Recent studies have indicated that dysbiosis in gut microbiota plays an important role in the formation of cholesterol gallstones.Aims:To explore the effect of probiotics supplementation on serum lipopolysaccharide(LPS)and the indicators of bile acid metabolism in patients with a high risk of cholesterol gallstone formation.Methods:Sixty choledocholithiasis patients undergoing ERCP lithotomy were recruited at the First Affiliated Hospital of Shihezi University from June 2021 to June 2023.Bile and stool samples were collected for bacterial culture.Then the patients were randomly allocated into two groups:patients in control group received conventional supportive therapy after calculus removal,while those in probiotics intervention group were given oral bifid triple viable enteric capsule 420 mg,twice a day for 6 months based on conventional therapy.Changes in serum levels of LPS,the cell wall component of Gram-negative bacteria,fibroblast growth factor 19(FGF19),the key molecule in bile acid metabolism,and cholesterol 7α-hydroxylase(CYP7A1),the rate-limiting enzyme of bile acid synthesis,were determined and compared between the two groups.Results:Escherichia coli and Klebsiella pneumoniae were the main pathogens in bile and stool of patients with choledocholithiasis.Six months after ERCP lithotomy,the serum levels of LPS and FGF19 were decreased,and the serum level of CYP7A1 was increased in both groups(all P<0.05),especially in probiotics intervention group(all P<0.05).Conclusions:Oral probiotics supplementation can reduce the serum LPS level and modulate the canonical pathway of enterohepatic circulation of bile acids--farnesoid X receptor(FXR)-FGF19 pathway in high-risk patients of cholesterol gallstone formation.These alterations reduce the cholesterol supersaturation in bile and inhibit the probability of cholesterol gallstone formation.

Objective:To evaluate the utility of the 9-gene panel as a differential diagnostic method for thyroid nodules within determinate cytological diagnosis and as a parallel diagnostic method for thyroid fine-needle aspiration (FNA) cytology.Methods:579 liquid-based cytology samples from 544 patients were collected after thyroid FNA diagnosis in our hospital from December 2014 to April 2021. Mutations at any site of 9 genes, namely, BRAF, NRAS, HRAS, KRAS, GNAS, RET, TERT, TP53, and PIK3CA as recorded by the Catalogue of Somatic Mutations in Cancer (COSMIC), were analyzed by next-generation sequencing. Taking postoperative histopathology and cytology results with definite benign or malignant diagnosis as the gold standard, the diagnostic efficacy of the 9-gene panel as a reclassified method for thyroid nodules with indeterminate cytological diagnosis and as a parallel diagnostic method for thyroid FNA cytology were evaluated and compared with that of the BRAF V600E single-gene detection method.Results:Of the 579 thyroid nodules, 196 (33.85%) were Bethesda Ⅱ, 11 (1.90%) were Bethesda Ⅲ, 31 (5.35%) were Bethesda Ⅳ, 27 (4.66%) were Bethesda Ⅴ, and 314 (54.23%) were Bethesda Ⅵ, as diagnosed by thyroid FNA cytology. Among these 579 thyroid nodules, 275 were tested positive for 9-gene mutations, with a mutation rate of 47.5%. Of the 329 thyroid nodules surgically removed, 30 (9.12%) were benign, 5 (1.52%) were borderline, and 294 (89.36%) were malignant. Regarding borderline nodules as malignant nodules, the mutation rates of the 9 genes in the 299 malignant thyroid nodules from high to low were BRAF 62.21% (186/299), NRAS 5.02% (15/299), HRAS 1.00% (3/299), PIK3CA 0.67% (2/299), GNAS 0.67% (2/299), KRAS 0.33% (1/299), TP53 0.33% (1/299), TERT 0.33% (1/299) and RET 0.00% (0/299). The malignant risks of the 9 genes from high to low were BRAF 100% (186/186), PIK3CA 100.00% (2/2), GNAS 100.00% (2/2), TERT 100.00% (1/1), TP53 100.00% (1/1), NRAS 78.95% (15/19), HRAS 75.00% (3/4), and KRAS 50.00% (1/2). For thyroid nodules of Bethesda Ⅲ-Ⅳ (indeterminate diagnosis), the sensitivity (SN) of the 9-gene panel in diagnosing thyroid cancer is 34.48% (10/29), the specificity (SP) is 61.54% (8/13), and the accuracy is 42.86% (18/42); whereas the SN of the BRAF V600E detection method is 0%. Therefore, the diagnostic efficiency of the 9-gene panel is significantly better than that of BRAF V600E single gene detection. For thyroid nodules of Bethesda Ⅱ-Ⅵ, the SN of the 9-gene panel in diagnosing thyroid cancer was 68.83% (254/369), the SP was 90.00% (189/210), the accuracy was 76.51% (443/579), and the area under the curve (AUC) was 0.79; whereas the SN of BRAF V600E single-gene detection in diagnosing thyroid cancer was 63.69% (235/369), the SP was 99.52% (209/210), the accuracy was 76.68% (444/579), and the AUC was 0.82. The SP of BRAF V600E detection is higher than that of the 9-gene panel ( P＜0.01), but there is no significant difference in SN, accuracy (both P＞0.05), and AUC ( Z=0.85, P=0.396) between them. Gene mutations indicating poor prognosis were detected in 4 nodules of papillary thyroid carcinoma and 1 nodules of follicular thyroid carcinoma, including 2 nodules with TERT and BRAF V600E co-mutations, 1 nodule with TP53 mutation, and 2 nodules with PIK3CA mutation. Conclusions:As a reclassified method for thyroid lesions with indeterminate cytological diagnosis, the 9-gene panel is better than BRAF V600E single gene detection. As a parallel diagnostic method of thyroid FNA cytology, the 9-gene panel has similar diagnostic efficacy as BRAF V600E single-gene detection. The 9-gene panel can detect individual cases with gene mutations indicating poor prognosis. The identification of patients with these special gene mutations has certain implications for the clinical management of them.
