To explore the advantages of traditional Chinese medicine （TCM） and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications （DMC）， refine key pathophysiological insights and treatment principles， and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine， hosted by the China Association of Chinese Medicine， was held in Beijing， 2024. Experts in TCM， Western medicine， and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis， diagnostic and treatment challenges， and mechanism research related to DMC， ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development， research prioritization， and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM， strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

OBJECTIVE: To evaluate the clinical efficacy and safety of Yangxue Qingnao Pills (YXQNP) combined with amlodipine in treating patients with grade 1 hypertension. METHODS: This is a multicenter, randomized, double-blind, and placebo-controlled study. Adult patients with grade 1 hypertension of blood deficiency and Gan (Liver)-yang hyperactivity syndrome were randomly divided into the treatment or the control groups at a 1:1 ratio. The treatment group received YXQNP and amlodipine besylate, while the control group received YXQNP's placebo and amlodipine besylate. The treatment duration lasted for 180 days. Outcomes assessed included changes in blood pressure, Chinese medicine (CM) syndrome scores, symptoms and target organ functions before and after treatment in both groups. Additionally, adverse events, such as nausea, vomiting, rash, itching, and diarrhea, were recorded in both groups. RESULTS: A total of 662 subjects were enrolled, of whom 608 (91.8%) completed the trial (306 in the treatment and 302 in the control groups). After 180 days of treatment, the standard deviations and coefficients of variation of systolic and diastolic blood pressure levels were lower in the treatment group compared with the control group. The improvement rates of dizziness, headache, insomnia, and waist soreness were significantly higher in the treatment group compared with the control group (P<0.05). After 30 days of treatment, the overall therapeutic effects on CM clinical syndromes were significantly increased in the treatment group as compared with the control group (P<0.05). After 180 days of treatment, brachial-ankle pulse wave velocity, ankle brachial index and albumin-to-creatinine ratio were improved in both groups, with no statistically significant differences (P>0.05). No serious treatment-related adverse events occurred during the study period. CONCLUSIONS Combination therapy of YXQNP with amlodipine significantly improved symptoms such as dizziness and headache, reduced blood pressure variability, and showed a trend toward lowering urinary microalbumin in hypertensive patients. These findings suggest that this regimen has good clinical efficacy and safety. (Registration No. ChiCTR1900022470).

OBJECTIVE: To explore the anti-photoaging properties of salvianolic acid B (Sal B). METHODS: The optimal photoaging model of human immortalized keratinocytes (HaCaT cells) were constructed by expose to ultraviolet B (UVB) radiation. The cells were divided into control, model and different concentrations of Sal B groups. Cell viability was measured via cell counting kit-8. Subsequently, the levels of oxidative stress, including reactive oxygen species (ROS), hydroxyproline (Hyp), catalase (CAT), and glutathione peroxidase (GSH-Px) were detected using the relevant kits. Silent information regulator 1 (SIRT1) protein level was detected using Western blot. The binding pattern of Sal B and SIRT1 was determined via molecular docking. RESULTS: Sal B significantly increased the viability of UVB-irradiated HaCaT cells (P<0.05 or P<0.01). Sal B effectively scavenged the accumulation of ROS induced by UVB (P<0.05 or P<0.01). In addition, Sal B modulated oxidative stress by increasing the intracellular concentrations of Hyp and CAT and the activity of GSH-Px (P<0.05 or P<0.01). The Western blot results revealed a substantial increase in SIRT1 protein levels following Sal B administration (P<0.05). Moreover, Sal B exhibited good binding affinity toward SIRT1, with a docking energy of -7.5 kCal/mol. CONCLUSION Sal B could improve the repair of photodamaged cells by alleviating cellular oxidative stress and regulating the expression of SIRT1 protein.

The angiogenic response is essential for the repair of ischemic brain tissue. Integrin α6 (Itga6) expression has been shown to increase under hypoxic conditions and is expressed exclusively in vascular structures; however, its role in post-ischemic angiogenesis remains poorly understood. In this study, we demonstrate that mice with endothelial cell-specific knockout of Itga6 exhibit reduced neovascularization, reduced pericyte coverage on microvessels, and accelerated breakdown of microvascular integrity in the peri-infarct area. In vitro, endothelial cells with ITGA6 knockdown display reduced proliferation, migration, and tube-formation. Mechanistically, we demonstrated that ITGA6 regulates post-stroke angiogenesis through the PI3K/Akt-eNOS-VEGFA axis. Importantly, the specific overexpression of Itga6 in endothelial cells significantly enhanced neovascularization and enhanced the integrity of microvessels, leading to improved functional recovery. Our results suggest that endothelial cell Itga6 plays a crucial role in key steps of post-stroke angiogenesis, and may represent a promising therapeutic target for promoting recovery after stroke.

OBJECTIVE: To explore the relationship between serum chloride levels and prognosis in patients with hepatic coma in the intensive care unit (ICU). METHODS: We analyzed 545 patients with hepatic coma in the ICU from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. Associations between serum chloride levels and 28-day and 1-year mortality rates were assessed using restricted cubic splines (RCSs), Kaplan-Meier (KM) curves, and Cox regression. Subgroup analyses, external validation, and mechanistic studies were also performed. RESULTS: A total of 545 patients were included in the study. RCS analysis revealed a U-shaped association between serum chloride levels and mortality in patients with hepatic coma. The KM curves indicated lower survival rates among patients with low chloride levels (< 103 mmol/L). Low chloride levels were independently linked to increased 28-day and 1-year all-cause mortality rates. In the multivariate models, the hazard ratio ( HR) for 28-day mortality in the low-chloride group was 1.424 (95% confidence interval [ CI]: 1.041-1.949), while the adjusted hazard ratio for 1-year mortality was 1.313 (95% CI: 1.026-1.679). Subgroup analyses and external validation supported these findings. Cytological experiments suggested that low chloride levels may activate the phosphorylation of the NF-κB signaling pathway, promote the expression of pro-inflammatory cytokines, and reduce neuronal cell viability. CONCLUSION Low serum chloride levels are independently associated with increased mortality in patients with hepatic coma.

Objective To analyze the diagnosis of occupational radiation diseases in Hubei Province, China between 1986 and 2021, and to assess the occupational health risks of radiation workers in Hubei Province. Methods A retrospective analysis was conducted on the diagnosis institutions, diagnosis case characteristics, and typical problems encountered in the diagnosis process of occupational radiation diseases in Hubei Province between 1986 and 2021. The findings were analyzed and discussed in conjunction with current occupational disease diagnosis standards and relevant regulations. Results There are currently 3 authorized occupational radiation disease diagnosis institutions in Hubei Province, with a total of 14 diagnostic physicians. Among them, 9 (64.3%) have senior professional titles and 12 (85.7%) possess postgraduate degrees; however, only one has a professional background in radiological medicine. From 1986 to 2021, a total of 139 cases of occupational radiation diseases were diagnosed. Chronic radiation sickness from external exposure accounted for 40.3%, radiation-induced cataract for 21.6%, and radiation-induced tumors for 18.7%. Among all cases, 81.4% were engaged in diagnostic radiology and interventional radiology, 3.1% were engaged in radiotherapy, and 3.1% were engaged in nuclear medicine. Diagnosed cases were primarily concentrated among medical radiation workers, especially those involved in X-ray diagnosis. Issues identified during the diagnosis process included illegal acceptance of subjects, non-standard dosage estimation, and illegal procedures. Conclusion The incidence of occupational radiation diseases in Hubei Province showed a declining trend. The diagnosis of occupational radiation diseases needs to be improved, and the occupational health management of key radiation workers should be further strengthened.

[Purpose]To analyze the incidence and mortality of thyroid cancer in Zhejiang cancer registration areas in 2021 and trends from 2000 to 2021.[Methods]Based on cancer data from 22 registries across Zhejiang Province between 2000 and 2021,the crude incidence/mortality rates,age-standardized incidence/mortality rates of thyroid cancer by Chinese and world standard population(ASIRC/ASMRC,ASIRW/ASMRW),cumulative rate(0～74 years old)and truncated rate(35～64 years old)were analyzed.Joinpoint regression model was employed to calculate the annual percentage change(APC)and average annual percentage change(AAPC)with 95％confidence in-terval(CI)for analyzing trends of thyroid cancer incidence and mortality rates from 2000 to 2021.[Results]The crude incidence rate of thyroid cancer increased from 3.62/105 in 2000 to 79.66/105 in 2021,and ASIRC rose from 3.11/105 to 69.49/105(AAPC=15.55％,95％CI:14.65％～16.61％).The AAPC for ASIRC was slightly higher in female(15.54％,95％CI:14.71％～16.49％)than that in male(15.02％,95％CI:13.53％～16.82％).The increase was significantly more pronounced in rural areas(AAPC=23.34％,95％CI:21.48％～25.33％)compared to urban areas(AAPC=14.12％,95％CI:13.15％～15.43％).Among age groups,the age group of 15～44 years old showed the fastest increase in crude incidence rate(AAPC=20.37％,95％CI:18.46％～22.31％),followed by the age group of 45～64 years old(AAPC=18.41％,95％CI:16.65％～20.19％).Between 2000 and 2021,the crude mortality rate of thyroid cancer rose from 0.34/105 to 0.56/105(AAPC=5.52％,95％CI:3.45％～7.70％),the trend of ASMRC was relatively stable.[Conclusion]From 2000 to 2021,the incidence of thyroid cancer in Zhejiang Province increased markedly,especially among females and younger to middle-aged adults,while the age-standardized mortality rate remained stable.

Neutrophil extracellular traps (NETs), intricate reticular structures released by activated neutrophils, play a pivotal regulatory role in the pathogenesis of malignant tumors. Lung cancer is one of the most prevalent malignancies globally, with persistently high incidence and mortality rates. Recent studies have revealed that NETs dynamically modulate the tumor microenvironment through unique pathological mechanisms, exhibiting complex immunoregulatory characteristics during the progression of lung cancer, and this discovery has increasingly become a focal point in tumor immunology research. This paper provides a comprehensive review of the latest advancements in NETs research related to lung cancer, offering an in-depth analysis of their impact on lung cancer progression, their potential diagnostic value, and the current state of research on targeting NETs for lung cancer prevention and treatment. The aim is to propose novel strategies to enhance therapeutic outcomes and improve the prognosis for lung cancer patients.
