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 investigate the influencing factors of stroke patients with hypertension and their compliance with antihypertensive drugs, and to provide targeted intervention measures for stroke prevention in hypertensive patients.  Methods Using the method of multi-stage cluster sampling, a total of 59,434 permanent residents aged 40 and above were selected from 48 monitoring sites in 9 cities of Hebei Province from December 2019 to December 2020. Unconditional logistic regression analysis was used to explore the influencing factors of stroke complicated with hypertension and the compliance of patients with antihypertensive drugs.  Results Among the 59 434 subjects, the prevalence rate of stroke was 4.33% and the prevalence rate of stroke complicated with hypertension was 82.47%. The results of univariate analysis showed that the proportion of women, rural areas, dyslipidemia, diabetes, obesity, and people with family history of stroke was higher in stroke patients with hypertension, and the difference was statistically significant (P<0.05). Multivariate logistic regression analysis showed that rural areas, dyslipidemia, diabetes, obesity, and family history of stroke significantly increased the risk of stroke, and the OR (95%CI) values were 1.29 (1.03-1.62), 1.39 (1.12-1.72), 1.58 (1.25-1.99), 1.61 (1.22-2.12) and 1.60 (1.26-2.04), respectively. Among stroke patients with hypertension, 92.71% of patients took antihypertensive drugs. It was found that women's compliance with antihypertensive drugs was good, with an OR (95%CI) value of 1.46 (1.01-2.09).  Conclusion The prevalence rate of stroke complicated with hypertension is high in people aged 40 and above in Hebei Province. Hypertensive people should lower blood lipids, control blood glucose, and lose weight as soon as possible to prevent the occurrence of stroke.

Purpose To explore the value of multi-modal ultrasound using two-dimensional grayscale ultrasound,ultrasound elastography and superb microvascular imaging in the ultra-high frequency ultrasound mode for evaluating benign and malignant skin tumors.Materials and Methods A retrospective analysis was conducted on 94 patients with skin tumors who were treated and confirmed by surgical pathology at the Second Affiliated Hospital of Anhui Medical University from January 2021 to December 2023,with 45 cases in the benign group and 49 cases in the malignant group.All patients underwent two-dimensional grayscale ultrasound,superb microvascular imaging and ultrasound elastography under the ultra-high frequency ultrasound mode before surgery,all the ultrasound parameters and clinical features were recorded.The differences in parameters between the benign and malignant groups were compared,and independent risk factors for tumor malignancy were analyzed.Results Univariate analysis showed there were statistically significant differences in age,maximum diameter,morphology,margin,superb microvascular imaging rating and ultrasound elastography score between the benign and malignant skin tumors groups(χ2/Z=-4.532-34.321,all P<0.05).Multivariate analysis showed that the older the patient(OR=1.052,P=0.023),the larger the maximum diameter of the lesion(OR=1.113,P=0.031),the irregular morphology(OR=21.975,P=0.025)and the higher the ultrasound elastography score(3 score:OR=7.310,P=0.026;4 score:OR=17.916,P=0.008),the higher the risk of tumor progression.Conclusion Older age,larger maximum diameter,irregular morphology and larger ultrasound elastography score(≥3 points)are independent risk factors for predicting malignant skin tumors.Multi-modal ultra-high frequency ultrasound has a certain value for the differential diagnosis of benign and malignant skin tumors.

Objective:To investigate the relationship between glycated hemoglobin (HbA1c) level and the occurrence of diabetes complications in patients with type 2 diabetes mellitus in 11 provinces in China.Methods:A total of 4 832 patients with type 2 diabetes mellitus from 60 surveillance sites in 11 provinces where national surveillance for chronic diseases and risk factors was conducted in 2010 were selected as the study participants, and a follow-up survey was conducted in 3 516 persons from 2016 to 2017, finally 3 427 patients were included in the analysis after excluding those data exception and incomplete data. Cox proportional risk regression model was used to evalaute the association between HbA1c level and the risk for diabetes complications (macroangiopathy, microangiopathy and diabetic foot), and subgroup analyses were conducted according to the baseline characteristics of the study participants, such as age, gender and smoking status.Results:A total of 3 427 study participants were included in final analysis of the follow up for an average of 6.2 years, in whom 395 suffered from macroangiopathy, 226 suffered from microangiopathy, and 57 suffered from diabetic foot later during the follow-up period. After adjusting for relevant confounders, using the HbA1c <7.0% as a reference, there was no increased risk for macrovascular lesions in the those with HbA1c levels of 7.0%-, 7.5%-, 8.0%-8.4%, and the risk for macrovascular lesions increased by 38% in those with HbA1c ≥8.5% ( HR=1.38,95% CI:1.06-1.80); the risk for microangiopathies increased by 131% ( HR=2.31,95% CI:1.46-3.65), 206%( HR=3.06,95% CI:1.91-4.90) and 208% ( HR=3.08,95% CI:2.20-4.30) in those with HbA1c levels of 7.5%-, 8.0%-, ≥8.5%, respectively; and the risk for diabetic foot increased by 253% ( HR=3.53, 95% CI: 1.89-6.59) in those with HbA1c level ≥8.5%. Subgroup analyses revealed an effect modifying effect of different diabetes diagnosis situations (previously diagnosed and newly diagnosed) on HbA1c level and the risk for microangiopathy. Conclusions:HbA1c level ≥7.5% would increase the risk for microangiopathy in patients with type 2 diabetes mellitus, the higher the level, the higher the risk, and HbA1c level ≥8.5% would increase the risk for macrovascular lesions and diabetic foot. It is necessary to strengthen the health education in diabetic patients to improve their awareness of blood glucose management and the importance of HbA1c level control to effectively reduce or delay the diabetes complications.

Objective:To examine the effect of cumulative hemoglobin A 1c (HbA 1c) levels and insulin dosage on insulin resistance (IR)-related metabolic disturbances in newly diagnosed patients with type 1 diabetes (T1D). Methods:This retrospective cohort study included T1D patients admitted to the Second Xiangya Hospital of Central South University from November 2015 to March 2023. Clinical data collected comprised age, sex, disease duration, insulin dosage, body mass index, waist circumference, blood pressure, HbA 1c levels, islet autoantibodies, and fasting blood lipid profiles. IR-related metabolic disturbances assessed were overweight, obesity, central obesity, hypertension, and dyslipidemia. Cox regression and cluster analyses were applied to assess the influence of cumulative HbA 1c and insulin dosage on these metabolic disturbances. Results:A total of 235 patients were included, with 97 males (41.3%) and 138 females (58.7%). The median age was 19.8 (13.3, 31.1) years, and the median follow-up duration was 30.8 (20.8, 45.6) months. During follow-up, 41.6% (72/173) of patients developed IR-related metabolic disturbances. Multivariate Cox regression analysis revealed that a cumulative HbA 1c ≥60 mmol/mol was an independent risk factor for any IR-related metabolic disturbance [ HR (95% CI): 1.739 (1.067-2.835) ] and for triglyceride abnormalities [ HR (95% CI): 3.277 (1.176-9.127)]. Additionally, a cumulative insulin dosage ≥0.5 U·kg -1·d -1 was identified as an independent risk factor for overweight, obesity, or central obesity [ HR (95% CI): 2.374 (1.059-5.323)]. Cluster analysis further identified that patients with higher levels of cumulative HbA 1c and insulin dosage, particularly those with adolescent-onset diabetes, had the highest likelihood of developing hypertension ( HR=2.460, 95% CI 1.008-6.005), overweight/obesity/central obesity ( HR=2.707, 95% CI 1.062-6.900), triglyceride abnormalities ( HR=5.495, 95% CI 1.842-16.391), high-density lipoprotein cholesterol abnormalities ( HR=11.054, 95% CI 4.107-29.751), and any IR-related metabolic disturbance ( HR=5.833, 95% CI 2.602-13.077). Conclusions:Elevated cumulative HbA 1c and insulin dosage levels in T1D patients are associated with an increased risk of developing IR-related metabolic disturbances. These findings underscore the urgent need for novel therapeutic strategies tailored to this population.

Objective:To investigate the clinical characteristics and genetic etiology of Duchenne muscular dystrophy (DMD) with myogenic tumors.Methods:The clinical data of 2 children with DMD combined with myogenic tumors diagnosed in Children′s Hospital Affiliated to Zhengzhou University in July 2021 and February 2022 were collected. The relevant literature was reviewed to summarize the clinical characteristics and explore the mechanism of the dystrophin ( DMD) gene in myogenic tumors. Results:A 6-year and 10-month-old boy with DMD (deletion of exon 45) and a 12-year-old boy with DMD (deletion of exon 51) were diagnosed with tumors. They were diagnosed with DMD for delayed motor development in the Department of Neurology of Children′s Hospital Affiliated to Zhengzhou University. They presented with painless masses in the waist. Postoperative pathological diagnosis: the pathology and immunohistochemistry of case 1 showed an alveolar rhabdomyosarcoma (ARMS) and both myogenin and myogenic differentiation 1 positive; the pathology and immunohistochemistry of case 2 showed an alveolar soft part sarcoma(ASPS) and transcription factor enhancer 3 positive; both cases were myogenic tumors. Literature review (including this paper) showed that there were in total 14 cases with DMD combined with myogenic tumors including 13 cases of rhabdomyosarcoma (RMS) and 1 case of ASPS. All of them are male, and the age of onset of the tumors was 4-17 years. Pathological subtypes were described in 6 cases of ARMS and 5 cases of embryonal RMS, and were not described in 2 cases. The 9 cases described all had large deletions in the DMD gene which can change the reading frame of the DMD gene, and all gene mutations did not exceed exon 62. Conclusions:DMD gene with deletion may increase the risk of having myogenic tumors, and RMS is more common, which is manifested as painless mass in early stage. All DMD gene deletions do not exceed exon 62 and lead to change of the gene reading frame with severe clinical phenotype and degenerative changes in muscle function.

Objective:To investigate the clinical characteristics of encephalocraniocutaneous lipomatosis (ECCL) in pediatric patients.Methods:A retrospective analysis was conducted on the clinical data of 2 ECCL cases admitted to Children′s Hospital Affiliated to Zhengzhou University between January 2024 and December 2024. Additionally, a review of relevant literature was performed to summarize the clinical features of this condition.Results:Case 1 is a male patient aged 2 years and 10 months, while case 2 is a female patient aged 8 months. Both patients presented with seizures and exhibited nevus psiloliparus on the scalp, non-scarring alopecia, nodular skin tags around the eyes, and ocular choristomas. Brain magnetic resonance imaging revealed leptomeningeal angiomatosis in both cases, with case 1 also demonstrating an intracranial lipoma and case 2 showing localized cerebral atrophy and an arachnoid cyst. Whole-exome sequencing of peripheral blood and copy number variation analysis in both cases did not identify any pathogenic variants. Additionally, no relevant pathogenic variants were detected in the scalp lesion tissue of case 2. A review of the literature revealed that, to date, there have been 5 reported domestic cases, 132 reported foreign cases in pediatric populations, totally 139 cases including 2 cases described in this article. Among these patients, 86 are male, 49 are female, and the gender of 4 cases remains unspecified. Clinical manifestations observed included seizures in 79.0% (64/81) of cases and developmental delay in 64.7% (57/88). Cutaneous lesions were characterized by non-scarring alopecia in 100% (97/97) of cases,non-hair-bearing fatty tissue nevi in 98.3% (58/59), nodular skin tags in 96.5% (56/58), and subcutaneous lipomas in 94.8% (73/77). Ocular lesions predominantly involved choristomas, occurring in 91.8% (90/98) of cases. Central nervous system abnormalities were identified as ventricular dilatation or hydrocephalus in 85.0% (68/80) of cases, intracranial lipomas in 82.1% (69/84), localized cerebral atrophy in 80.9% (34/42), intracranial vascular anomalies in 74.1% (23/31), and spinal lipomas in 66.6% (30/45).Conclusions:ECCL is an uncommon neurocutaneous disorder with the potential to impact various organ systems, notably the integumentary, ocular, and central nervous systems. Pediatric patients may exhibit symptoms such as seizures, developmental delays, and additional clinical manifestations, necessitating vigilant monitoring and management.
