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.

Purpose To explore the characteristics of left and right ventricular myocardial strain in hypertensive heart disease(HHD)assessed by magnetic resonance feature tracking technique,and to assess the effect of HHD on right ventricular function.Materials and Methods A retrospective analysis was performed on 40 patients with HHD at the General Hospital of Ningxia Medical University from January 2022 to August 2023.Among these 40 HHD patients,19 presented with a left ventricular ejection fraction(LVEF)of≥50%,and 21 presented with an LVEF of<50%.Additionally,25 healthy controls were enrolled.All subjects underwent cardiac magnetic resonance imaging.The cine sequence images were imported into cardiac post-processing analysis software(QIR suite software).The left ventricular radial strain(LVRS),left ventricular circumferential strain(LVCS),left ventricular longitudinal strain(LVLS)and right ventricular longitudinal strain(RVLS)were measured,and left and right ventricular strain parameters of the three groups were analyzed statistically.Results The absolute values of LVRS,LVCS,LVLS and RVLS in the HHD group with LVEF<50%were lower than those in the normal control group(t=7.48,-12.69,-8.19,-6.32,all P<0.001)and those in the HHD group with LVEF≥50%(t=5.97,-8.88,-4.50,-4.90,all P<0.001);the area under the curve values of LVRS,LVCS,LVLS and RVLS for distinguishing HHD from normal controls were 0.804,0.785,0.829,0.832,respectively,and the cut-off values of LVRS,LVCS,LVLS and RVLS were 22.9%,-10.0%,-11.9%and-18.7%,respectively.Conclusion Magnetic resonance feature tracking technique can detect left and right ventricular myocardial dysfunction in HHD at an early stage and can provide a new basis for evaluating cardiac function.

Triple-negative breast cancer (TNBC) is a highly aggressive malignancy predominantly managed via chemotherapy. Our clinical sample analysis revealed a significant correlation between elevated CD24 expression in TNBC tumor cells and patient survival rates. We developed a novel antibody-drug conjugate (ADC), named HN03, consisting of an antibody with engineered cysteines for site-specific conjugation with a low toxic nitric oxide (NO) precursor as its payload through a novel Pt(IV)-mediated bioorthogonal self-cleavable linker. HN03 specifically targets tumor cells expressing high levels of CD24, concurrently generating cisplatin and releasing NO upon activation. HN03 also exhibited potent in vitro and in vivo antitumor activity. It significantly reduced tumor growth at various doses, prevented tumor metastasis, with markedly lower toxicity than traditional chemotherapy agents. We found that a key mechanism of its action involved inducing apoptosis and endoplasmic reticulum stress, substantially decreasing the number of M2-type macrophages. Overall, HN03 stands out as a promising therapeutic option for TNBC, offering a targeted treatment with reduced side effects and the potential for improved outcomes. Furthermore, using Pt(IV) in the linker and an NO precursor as the payload enhances the versatility of the Antibody-NO donor Conjugate (ANC), offering new avenues for the design of the next generation of ADCs.

Objective:To observe any effect of percutaneous tibial nerve stimulation (PTNS) combined with electro-acupuncture on detrusor overactivity after a spinal cord injury.Methods:Forty spinal cord injury survivors with neurogenic detrusor overactivity were randomly assigned to a control group or an observation group, each of 20. Both groups received routine bladder training and electro-acupuncture modulating 3 sacral spinal nerves. The observation group also received 20 minutes of bilateral PTNS five times a week for 8 weeks. The frequency was 10Hz with a pulse width of 200μs. Before and after the treatment, both groups′ urination frequency, incontinence and average daily urine volume were assessed using a urodynamics analyzer, bladder diaries and an incontinence quality of life questionnaire (I-QOL).Results:After treatment, the average involuntary detrusor contraction volume (IDCV), maximum detrusor pressure at filling time (P det·max), bladder compliance (BC), residual volume and the TL value of the electromyogram of the urethral sphincter (LgTLR) had all improved significantly in both groups. The 1st IDCV, BC and LgTLR of the observation group were then significantly better than in the control group, on average, with the average P det·max and residual volume significantly lower than in the control group. The average daily single urine output and I-QOL score of both groups had increased significantly, while the average daily urination frequency and frequency of urinary incontinence had decreased significantly. Both were again significantly better in the observation group. Conclusion:Combining percutaneous electrical stimulation of the tibial nerves with electro-acupuncture can effectively inhibit detrusor overactivity after a spinal cord injury, reducing urinary incontinence.

Objective To analyze the current situation of dietary diversity and caregiver self-efficacy for complementary feeding among infants and young children aged 6 to 23 months in rural Nanchong city,Sichuan province,and to explore the relationship between dietary diversity and caregiver self-efficacy.Methods Multi-stage randomized cluster sampling method was used to select infants and young children aged 6 to 23 months and their caregivers in rural areas of Nanchong city,Sichuan province as the subjects.A structured questionnaire was designed to collect the basic information of the subjects,dietary diversity,and caregiver self-efficacy for comple-mentary feeding.Multivariate Logistic regression was adopted to analyze the relationship between the dietary diver-sity and caregiver self-efficacy for complementary feeding of infants and young children.Results A total of 770 pairs of infants and young children and their caregivers were included.The minimum pass rate of dietary diversity was 61.56% (474/770)for all the infants and young children and 45.00% (108/240),69.16% (287/415),and 68.70% (79/115)for the infants and young children aged 6 to 11,12 to 17,and 18 to 23 months,respective-ly.The results of regression analysis showed that the caregiver self-efficacy of complementary feeding was a contributing fac-tor for qualified dietary diversity of infants and young children in the case of other confounders being controlled(OR = 1.42,95% CI=1.17-1.73,P<0.001).Conclusion The dietary diversity for infants and young children in rural Nan-chong city,Sichuan province needs to be improved,and caregivers with higher self-efficacy of complementary feeding are more likely to provide diversified complementary feeding for infants and young children.

Objective To investigate the current status of physical activity and depressive symptoms a-mong middle-aged and older adults in Chengdu,Sichuan and explore the relationship between physical activity and depressive symptoms.Methods Multi-stage proportional stratified random sampling was employed to select middle-aged and older adults aged ≥45 years as the participants,and face-to-face interviews were carried out to collect data.Logistic regression was adopted to explore the relationship between physical activity and depressive symptoms in middle-aged and older adults.The trend test was performed for the relationship between different lev-els of physical activity and depressive symptoms.The subgroup analysis and the test for multiplicative interactions were conducted for the relationship between physical activity and depressive symptoms.Results A total of 4376 middle-aged and older adults were included.Among them,14.58％(638/4376),25.98％(1137/4376),and 27.83％(1218/4376)had depressive symptoms,failed to reach the guideline-recommended standards of physical activity,and were at low levels of physical activity,respectively.There was a negative association be-tween reaching guideline-recommended physical activity standard and depressive symptoms in middle-aged and ol-der adults(OR=0.713,95％CI=0.589-0.861,P＜0.001).In addition,moderate levels(OR=0.714,95％CI=0.586-0.871,P=0.001)and high levels of physical activity(OR=0.705,95％CI=0.548-0.906,P=0.006)had negative associations with the presence of depressive symptoms.The trend test revealed that the negative association between physical activity and depressive symptoms in middle-aged and older adults enhanced as the level of physical activity increased(Pfor trend=0.001).The subgroup analysis and the test for multiplicative interactions revealed that neither reaching guideline-recommended physical activity standards or not nor the physi-cal activity level had an interaction with each of the subgroups(all Pfor interaction＞0.05).Conclusions The current status of depressive symptoms among middle-aged and older adults in Chengdu,Sichuan needs to be ameliora-ted.A negative association existed between reaching the guideline-recommended physical activity standard and pres-ence of depressive symptoms,and the negative association enhanced as the physical activity level elevated.

Microneedles (MNs) serve as a revolutionary paradigm in transdermal drug delivery, heralding a viable resolution to the formidable barriers presented by the cutaneous interface. This review examines MNs as an advanced approach to enhancing dermatological pathology management. It explores the complex dermis structure and highlights the limitations of traditional transdermal methods, emphasizing MNs' advantage in bypassing the stratum corneum to deliver drugs directly to the subdermal matrix. The discourse outlines the diverse typologies of MNs, including solid, coated, hollow, hydrogel, and dissolvable versions. Each type is characterized by its unique applications and benefits. The treatise details the deployment of MNs in the alleviation of cutaneous cancers, the administration of inflammatory dermatoses such as psoriasis and atopic dermatitis, and their utility in wound management. Additionally, the paper contemplates the prospects of MNs within the realm of aesthetic dermatology and the burgeoning market traction of cosmetic MN formulations. The review summarizes the scientific and commercial challenges to the clinical adoption of MN therapeutics, including dosage calibration, pharmacodynamics, biocompatibility, patient compliance, sterilization, mass production, and regulatory oversight. It emphasizes the need for ongoing research, innovation, and regulatory harmonization to overcome these obstacles and fully realize MNs' potential in treating skin diseases and improving patient welfare.

Objective:To observe any effect of dynamic motor instability training on the balance and postural control of stroke survivors.Methods:Forty stroke survivors with poor balance were randomly divided into a control group and an observation group, each of 20. In addition to routine rehabilitation, the observation group was given 20 minutes of dynamic motor instability training, 5 days a week for 8 weeks, while the control group underwent routine rehabilitation for the same length of time. Before and after the intervention, surface electromyogram of the rectus femoris, biceps femoris, and erector spinae were recorded during perturbation. Activation time and the intensity of the anticipatory and complementary postural adjustments (APAs and CPAs) were also observed. Balance and lower limb motor functioning were assessed using the Berg balance scale (BBS), the Fugl-Meyer lower extremity assessment (FMA-LE), and GaitWatch analysis.Results:After the treatment the average activation time of the rectus femoris, biceps femoris in the affected side and those of the biceps femoris [(-84.31±5.74)s] and erector spinae in the intact side in APAs were all significantly shorter in the observation group than in the control group, while the average activation intensity of the rectus femoris and erector spinae was significantly greater. There was no significant difference in the activation intensity of each muscle group in CPAs after the treatment. After the intervention the average BBS score, FMA-LE score, stride length and walking speed of the observation group all were significantly better than the control group′s averages.Conclusions:Supplementing traditional rehabilitation training with dynamic motor instability training can further improve the posture control of stroke survivors and promote recovery of their balance and walking ability.
