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 explore the relationship between serum soluble semaphorin 4D(sSema4D),CXC chemokine ligand 12(CXCL12)levels and left ventricular diastolic function in young and middle-aged patients with essential hypertension.Methods A total of 148 young and middle-aged patients with essential hyperten-sion admitted to a hospital from November 2020 to November 2022 were selected as the study subjects,and were grouped into left ventricular diastolic dysfunction group(n=41)and normal left ventricular diastolic function group(n=107)according to their left ventricular diastolic function.The serum levels of sSema4D and CXCL12 were detected by enzyme-linked immunosorbent assay.Pearson correlation analysis was applied to analyze the correlation between the serum levels of sSema4D and CXCL12 and the left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),left ventricular septal thickness(IVST),left ventricular end-diastolic posterior wall thickness(LVPWT),left ventricular ejection fraction(LVEF),E peak/A peak(E/A)and maximum velocity of tricuspid regurgitation(TRVmax).The predictive value of ser-um sSema4D and CXCL12 levels in left ventricular diastolic dysfunction in young and middle-aged patients with essential hypertension was analyzed by receiver operating characteristic(ROC)curve.Results There were significant differences in diastolic blood pressure and gender between the left ventricular diastolic dys-function group and the left ventricular diastolic function normal group(P＜0.05).Compared with the normal left ventricular diastolic function group,serum levels of sSema4D,CXCL12 in the left ventricular diastolic dys-function group were obviously increased,and the difference was statistically significant(P＜0.05).Compared with normal left ventricular diastolic function group,IVST and LVPWT in the left ventricular diastolic dys-function group were significantly increased,and E/A was significantly decreased,with statistical significance(P＜0.05).Pearson correlation analysis showed that serum sSema4D and CXCL12 levels were positively cor-related with LVEDD,IVST and LVPWT(P＜0.05),and negatively correlated with E/A(P＜0.05).ROC curve analysis showed that the area under the curve(AUC)of serum sSema4D and CXCL12 combined in pre-dicting left ventricular diastolic dysfunction in young and middle-aged patients with essential hypertension was 0.894(95％CI:0.833-0.939),which was significantly greater than that of sSema4D alone in predicting left ventricular diastolic dysfunction in young and middle-aged patients with essential hypertension(Z=3.142,P=0.002)and CXCL12 alone predicted the AUC of left ventricular diastolic dysfunction in young and middle-aged patients with essential hypertension(Z=3.268,P=0.001).Conclusion Serum sSema4D and CXCL12 levels are associated with left ventricular diastolic function in young and middle-aged patients with essential hypertension.

Objective To study the influence of rosemary essential oil inhalation on the memory of mice experiencing sleep deprivation and to delineate the possible mechanisms involved.Methods C57BL/6J mice were randomly divided into four experimental groups in this study:a control group(Con),a control group with rosemary essential oil inhalation(Con+REO),a sleep deprivation group(SD)and a sleep deprivation group with rosemary essential oil inhalation(SD+REO).A 72-hour sleep deprivation model was induced using the multiple platform water environment method,with the Con+REO and SD+REO groups exposed to rosemary essential oil inhalation.Cognitive function was evaluated through Y-maze and novel object recognition tests.The hippocampal tissue was analyzed for superoxide dismutase(SOD)activity and the concentrations of malondialdehyde(MDA)and glutathione(GSH).ELISA was used to determine the levels of norepinephrine(NE),dopamine(DA),and serotonin 5-hydroxytryptamine(5-HT)in the hippocampus.The expression levels of postsynaptic density 95(PSD95)and brain-derived neurotrophic factor(BDNF)in the hippocampus were determined using immunoblotting techniques.Results Compared with the Con and Con+REO groups,the SD group demonstrated a significant reduction in the spontaneous alternation percentage in the Y-maze as well as the novel object recognition index.Additionally,there was a pronounced decrease in hippocampal SOD activity and GSH content,a substantial elevation in MDA levels,and a decrease in the levels of DA,NE,and 5-HT.The expressions of PSD95 and BDNF proteins also decreased.In comparison with the SD group,the SD+REO group exhibited a significant increase in the spontaneous alternation percentage in the Y-maze and the novel object recognition index.There was also a marked increase in hippocampal SOD activity and GSH content,a reduction in MDA levels and elevated levels of NE and DA.Moreover,the expressions of PSD95 and BDNF proteins were upregulated.Conclusion The inhalation of rosemary essential oil enhances the memory of sleep-deprived mice,and the underlying mechanism may involve the mitigation of oxidative stress within the hippocampal tissue,the modulation of neurotransmitter levels,and the facilitation of synaptic plasticity.

Microribonucleic acid (miRNAs) is a widely existing endogenous single-stranded non-coding small RNA, which is stably expressed in tissues and body fluids. By complementing messenger RNA(mRNA) sequences, miRNAs degrade target mRNA and block the expression of protein-coding genes, playing a key role in post-transcriptional regulation and different biological processes. In recent years, more and more studies have shown that miRNAs are closely related to the occurrence and development of tumors. Among them, as a member of the miRNAs family, microribonucleic acid-196 (miR-196) is abnormally expressed in the serum, tissues and cells of patients with non-small cell lung cancer, participating in the occurrence and development of non-small cell lung cancer and playing an important regulatory role in various biological processes such as proliferation, invasion and metastasis, providing diagnostic evidence for early screening of non-small cell lung cancer.This paper reviews the progress of miR-196 in the development and diagnosis of non-small cell lung cancer.

Galactinol synthase (GolS) is a key enzyme in the biosynthetic pathway of raffinose family oligosaccharides (RFOs) and plays an important role in plant responses to abiotic stresses. However, the molecular characteristics of the GolS family members in soybean was not well-known. In this study, six members of GmGolS gene family were genome-widely identified, and their physicochemical properties, chromosomal localization, evolutionary relationship, gene structure, conserved motifs, secondary structure, tertiary structure, tissue-specific expression patterns and the expression levels under salt and drought stresses were analyzed. The results showed that six soybean GolS genes were unevenly distributed on four chromosomes, the range of the isoelectric points of six GmGolS proteins was 5.45-6.08, the molecular weight range was 37 567.07-38 817.59 Da, and the number of amino acids was 324-339 aa. The results of subcellular localization showed that 4 proteins were located in the chloroplast, and 2 proteins in the cytoplasm. Phylogenetic tree analysis showed that the members of the soybean GolS gene family were closely adjacent to each other, and were evolutionarily conservative. Six gene members contain 3 or 4 exons. Prediction of secondary and tertiary structures showed that the spatial structure of proteins of all family members was mainly composed of α-helix and random coil structure, with less β-turn and extended chain structure. Tissue-specific expression analysis showed that six GmGolS members expressed to variable degrees in seeds, roots, root hairs, flowers, stems, pods, nodules and leaves. Expression analysis based on qRT-PCR showed that all GmGolS genes showed different degrees of up-regulated expression under salt and drought treatment, indicating that these genes may be related to the response of plants to salt-tolerance and drought-resistance. These results may facilitate subsequent functional analysis of soybean GolS genes.

Objective:To analyze curative efficacy and pronosis of three-dimensional reconstruction combined with 3D printing assisted minimally invasive surgery in the treatment of hepatolithiasis.Methods:92 patients with complex hepatolithiasis treated by minimally invasive surgery in Qingdao Hospital affiliated to Shandong First Medical University from November 2018 to January 2020 were retrospectively selected. According to different surgical positioning methods, they were divided into the control group [50 cases , conventional computer tomography (CT) positioning] and the observation group (42 cases, 3D reconstruction combined with 3D printing technology). The curative effect, stone residue rate, operation related indexes, complications and recurrence rate were compared between the two groups.Results:The excellent and good rate of the observation group was higher than that of the control group (95.2% vs 80.0%), and the rate of residual stones after surgery was lower than that of the control group (4.0% vs 22.0%), with statistically significant difference (both P<0.05). Compared with the control group, the observation group had shorter operation time, less intraoperative blood loss and postoperative abdominal drainage volume, shorter postoperative abdominal drainage time and hospital stay, with statistically significant difference (all P<0.05). The incidence of postoperative complications and recurrence rate in the observation group were lower than those in the control group (11.9% vs 30.0%, 2.4% vs 18.0%), with statistically significant difference (both P<0.05). Conclusions:Three-dimensional reconstruction combined with 3D printing assisted minimally invasive surgery is effective in the treatment of complex hepatolithiasis and can reduce the recurrence rate.

Objective:To explore the existing issues in radiation protection during the treatment of 131I by means of measuring the ambient dose equivalent rate to patients with thyroid cancer and the dose equivalent to the surface of chest of patients during hospitalization. Methods:The ambient dose equivalent rate (peer) was measured by using gamma ray detector for selected 78 patients who received 131I treatment in a hospital 10 min, 1 d, 2 d, 3 d and 5 d after administration with 131I. The measurements were made at distances of 5 cm, 0.5 m and 1 m from the body surface in front, rear, left and right directions. The photoluminescence dosimeter on the chest of the patients was used to measure the effective dose during hospitalization period (6 d). Results:The ambient dose equivalent rate on the surface of chest of patients was up to 4.81 mSv/h 10 min after administration of medicine. The dose equivalent on the surface of chest of patients before discharge ranged 2.6-64.1 μSv/h. The cumulative dose on chest surface during hospitalization was 15.9-58.8 mGy. There was a significant difference in the dose rate at 5 cm from the body surface between 3.7 GBq group and 5.55 GBq group 10 min after medication ( t=-6.11, P<0.05). There was a significant difference in the dose rate at 5 cm from the body surface between male and female groups 10 min after medication ( t=4.52, P < 0.05). There was no significant difference in other groups ( P > 0.05). Conclusions:During the 131I treatment, patients had high level of radiation around them, so it is necessary to strengthen the protection and management of patients and reduce unnecessary exposure to the public.
