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 analyze the change trends in the body shape indicators and proportions of students in Harbin from 2010 to 2024, and to investigate ergonomic compatibility of functional dimensions of school desks and chairs with current student shape indicators, so as to provide a reference for revising furniture standards of desks and chairs. Methods: Between September and November of both 2010 and 2024, a combination of convenience sampling and stratified cluster random sampling was conducted across three districts in Harbin, yielding samples of 6 590 and 6 252 students, respectively. Anthropometric shape indicators cluding height, sitting height, crus length, and thigh length-and their proportional changes were compared over the 15-year period. The 2024 data were compared with current standard functional dimensions of school furniture. The statistical analysis incorporated t-test and Mann-Whitney U- test. Results: From 2010 to 2024, average height increased by 1.8 cm for boys and 1.5 cm for girls; sitting height increased by 1.5 cm for both genders; crus length increased by 0.3 cm for boys and 0.4 cm for girls; and thigh length increased by 0.5 cm for both genders. The ratios of sitting height to height, and sitting height to leg length increased by less than 0.1 . The difference between desk chair height and 1/3 sitting height ranged from 0.4-0.8 cm. Among students matched with size 0 desks and chairs, 22.0% had a desk to chair height difference less than 0, indicating that the desk to chair height difference might be insufficient for taller students. The differences between seat height and fibular height ranged from -1.4 to 1.1 cm; and the differences between seat depth and buttock popliteal length ranged from -9.8 to 3.4 cm. Among obese students, the differences between seat width and 1/2 hip circumference ranged from -20.5 to -8.7 cm, while it ranged from -12.2 to -3.8 cm among non obese students. Conclusion Current furniture standards basically satisfy hygienic requirements; however, in the case of exceptionally tall and obese students, ergonomic accommodations such as adaptive seating allocation or personalized adjustments are recommended to meet hygienic requirements.

Objective To investigate the role of mitochondrial transcription factor A (TFAM) in platinum-resistant ovarian cancer cells and its effects on metabolic reprogramming and sensitivity to platinum-based drugs Methods The mitochondrial function and metabolic characteristics of platinum-resistant ovarian cancer cells were analyzed. A TFAM-overexpressing cell model was established to assess its effects on platinum sensitivity, mitochondrial function, and aerobic glycolysis; and glycolytic enzyme and drug-resistant protein expression were analyzed. Results Platinum-resistant ovarian cancer cells exhibited considerable mitochondrial dysfunction (reduced oxygen consumption rate) and enhanced aerobic glycolysis (increased extracellular acidification rate, glucose uptake, and lactate production). TFAM was downregulated in resistant cells. Meanwhile, TFAM overexpression significantly enhanced platinum sensitivity (P<0.01), restored mitochondrial function, and inhibited aerobic glycolysis. The expression levels of glycolytic enzymes and drug-resistant proteins were also downregulated (P<0.05). Conclusion TFAM downregulation is associated with suppressed oxidative phosphorylation and enhanced aerobic glycolysis in platinum-resistant ovarian cancer cells. TFAM overexpression can restore cellular dependence on oxidative phosphorylation and increase platinum sensitivity, suggesting that TFAM is a potential therapeutic target for reversing platinum resistance.

AIM: To investigate timing of glucocorticoids use in the treatment of syphilitic uveitis.METHODS: A retrospective study was conducted in 110 patients(134 eyes)with syphilitic uveitis diagnosed from January 2008 to January 2021, of whom 24 were binocular. The time from onset to treatment was 1 d to 3 mo. They were divided into three groups according to the treatment, including 98 eyes with completed clearely fundus lesions and no abnormalities in fundus fluorescein angiography(FFA)+ indocyanine green angiography(ICGA)+ optical coherence tomography(OCT)after treated with antibiotics alone for 1 to 2 wk in single antibiotics group, 26 eyes with in completely cleared fundus lesions and retinal vessels wall staining observed by FFA or choroidal weak fluorescence observed by ICGA after standard antisyphilitic treatments for 1 to 2 wk in first antibiotics followed by hormones group, and 10 eyes treated according to uveitis at other hospital in the absence of a clear cause of disease, that was intravenously dripped with 250 mL of normal saline and 10 mg of dexamethasone once a day for 7 to 10 d in total, then clearly diagnosed as syphilitic uveitis by Treponema pallidum particle agglutination(TPPA)test after receiving treatment for 10 to 14 d in hormones followed by antibiotics group. The best corrected visual acuity, slit-lamp examination, fundus photography, OCT, FFA, ICGA and prognosis of the three groups of patients were compared.RESULTS: There were statistically significant difference in the best corrected visual acuity, optic disc, retinal vasculitis, choroidal weak fluorescence, and RPR titer before and after treatment of the three groups of patients. The prognosis of the hormones followed by antibiotics group was lower than that in the single antibiotics group and antibiotics followed by hormones group, and the proportion of “good” prognosis in the antibiotics followed by hormones group was larger than that in other groups.CONCLUSION: Early diagnosis and regular treatment of syphilitic uveitis has a good overall prognosis, and giving large doses of glucocorticoids before thorough antisyphilitic treatments is not conducive to the recovery of disease. In patients with residual lesions after standard antisyphilitic, the application of small doses of glucocorticoids is helpful for the recovery of the disease.

Chronic cough is one of the common complications after pulmonary nodule surgery. Its etiology and pathogenesis are complex， and syndrome differentiation and treatment in traditional Chinese medicine （TCM） require comprehensive consideration of the distinct characteristics across the preoperative， intraoperative， and postoperative phases. Prior to surgery， there may be healthy qi depletion with lingering pathogens in the lungs； during surgery， metal instruments may injure the body， leading to qi and blood damage； after surgery， the depletion of healthy qi worsens， with dual deficiency of lung and spleen qi and yin as the root condition， often complicated by pathogens such as wind， phlegm， stagnation， and stasis. Treatment should follow the principle of comprehensively considering all three phases with a focus on the postoperative phase. Replenishing deficiency is the primary， particularly by tonifying qi and nourishing yin， as well as supplementing the lung and fortifying the spleen. For different accompanying syndromes， therapeutic methods such as dispelling wind， resolving phlegm， relieving stagnation， and unblocking stasis should be applied accordingly， while aggressive purgative herbs should be used with caution to avoid depletion of qi and blood injury.

Cells and exosomes derived from them are extensively used as biological carrier systems. Cells demonstrate superior targeting specificity and prolonged circulation facilitated by their rich array of surface proteins, while exosomes, due to their small size, cross barriers and penetrate tumors efficiently. However, challenges remain, cells' large size restricts tissue penetration, and exosomes have limited targeting accuracy and short circulation times. To address these challenges, we developed a novel concept termed exosomal spheres. This approach involved incorporating platelet-derived exosomes shielded with phosphatidylserine (PS) and linked via pH-sensitive bonds for drug delivery applications. The study demonstrated that, compared with exosomes, the exosomal spheres improved blood circulation through the upregulation of CD47 expression and shielding of phosphatidylserine, thereby minimizing immune clearance. Moreover, the increased expression of P-selectin promoted adhesion to circulating tumor cells, thereby enhancing targeting efficiency. Upon reaching the tumor site, the hydrazone bonds of exosome spheres were protonated in the acidic tumor microenvironment, leading to disintegration into uniform-sized exosomes capable of deeper tumor penetration compared to platelets. These findings suggested that exosome spheres addressed the challenges and offered significant potential for efficient and precise drug delivery.

Objective:To investigate the correlations of urinary adverse reactions with dose to the bladder and urethra during external pelvic irradiation for locally advanced cervical cancer.Methods:This study retrospectively collected relevant dosimetric parameters and urinary symptoms, such as frequent, urgent, and painful urination, from locally advanced cervical cancer patients treated with external pelvic irradiation in the Department of Oncology, Affiliated Hospital of Guizhou Medical University. The dosimetric parameters examined in this study included the maximum, minimum, and mean doses to bladder and urethra (i.e., Dmax, Dmin and Dmean), mean doses received in an area of 0.1, 1, and 2 cm 3 around the planning target volume, D0.1 cm 3, D1 cm 3, D2 cm 3, and percentages of irradiated volumes in the whole organ volume under doses of 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 Gy, V5 Gy, V10 Gy, V15 Gy, V20 Gy, V25 Gy, V30 Gy, V35 Gy, V40 Gy, V45 Gy, V50 Gy. Then the correlations between urinary symptoms and these dosimetric parameters were analyzed using the independent-sample t-test and the Logistic regression model. Results:The median volumes of bladder and urethra were 294.8 and 4.71 cm 3, respectively. Patients were divided into two groups based on the median division. The univariate analysis showed that urethral Dmax, Dmin, Dmean, V5 Gy, V10 Gy, V15Gy, V20 Gy, V25 Gy, V30 Gy, V35 Gy, V40 Gy, V45 Gy and V50 Gy correlated with urinary complications ( t = 14.30, 21.65, 32.19, 33.36, 16.62, 17.91, 21.52, 20.11, 12.27, 37.25, 30.18, 36.24 and 21.98, P<0.05). The multivariate analysis further indicates that urethral D2 cm 3, V20 Gy, V40 Gy and Bladder V40 Gy, D1 cm 3, D2 cm 3 were independent predictors of grade 2 urinary adverse reactions ( P<0.05). Conclusions:This study reported the correlations of relevant dosimetric parameters of urethra with urinary toxicity during external pelvic irradiation. It holds that urethral D2 cm 3, V20 Gy and V40 Gy should be restricted to minimize the risks of grade 2 urinary complications.

Objective To construct,implement and evaluate the effectiveness of the virtual simulation technology-based prenatal health education course.Methods The curriculum included 4 parts:"warm delivery room and easy delivery","medicated analgesic delivery","non-medicated analgesic delivery"and"early maternal and infant health care".From May to September 2022,100 primiparas in an obstetrics and gynecology hospital in Zhejiang Province were investigated by convenient sampling method.Random number table method was used to divide the participants into an experimental group and a control group,with 50 participants per group.The control group received conventional health education,while the experimental group received an augmented virtual reality technology-based prenatal health education course during the late stages of pregnancy on this basis.We conducted a post-intervention comparative analysis of antenatal anxiety levels,fear of childbirth,and birth outcomes between the 2 groups.Furthermore,a post-intervention satisfaction survey was administered to the experimental group.Results After intervention,the antenatal anxiety of the experimental group was lower than that of the control group(x2=4.943,P=0.026),and the decrease in fear of childbirth scores was higher than that of the control group(t=3.200,P=0.002).The experimental group was highly satisfied with all of the 4 dimensions of the course,and the overall evaluation was(31.8±3.23)points.However,there were no significant differences in vaginal delivery rate,postpartum bleeding volume,postpartum hemorrhage incidence,perineal injury degree and duration of each labor stage between the 2 groups(P＞0.05).Conclusion The virtual reality technology-based prenatal health education course was effective in improving the antenatal anxiety and fear of childbirth of primipara,and the use satisfaction is high.

Objective:To analyze the passive smoking exposure and its influencing factors in non-smokers aged≥18 in Tianjin.Methods:This was a cross-sectional study. Based on the 2018 Tianjin Adults Noncommunicable Disease and Nutrition Surveillance, non-smokers aged≥18 years old at 7 surveillance sites were selected as the research objects, taking 2018 population data of Tianjin as the standard population, the sample data were weighted to analyze the general demographic characteristics, the level of passive smoking exposure, the cognition of tobacco harm, and the influencing factors of passive smoking exposure. Pearson χ 2 test was used to compare the rate between groups, and the influencing factors were analyzed by unconditional logistic regression. Results:After weighted, the passive smoking exposure rate was 51.5%, among non-current smokers, the awareness rates of smoking related lung cancer and passive smoking related adult lung cancer were 83.3% and 80.0%, respectively. The awareness rates of smoking related stroke and passive smoking related heart disease in adults were 61.4% and 66.4%, respectively. The awareness rate that smoking related stroke was higher in the non-passive smoking exposed group than in the secondhand smoke exposed group (62.7% vs 60.3%, P<0.05). There was no statistical difference in the awareness rate of smoking related heart attacks and lung cancer as well as passive smoking related adult heart disease, adult lung cancer, and lung disease in children between the passive smoking exposed group and the non-passive smoking exposed group (all P>0.05). The awareness rate of smoking related three diseases (stroke, heart attack and lung cancer) was 57.9% and the awareness rate of passive smoking related three diseases (heart disease in adults, lung cancer and lung disease in children) was 64.9% in non-current smokers. Among men, undergraduate or above was a protective factor for second-hand smoke exposure. Heads, clerical and related personnel of state organs, party and mass organizations, enterprises and public institutions were risk factors for secondhand smoke exposure. Among women, age ≥60 years and high education were protective factors for secondhand smoke exposure. Conclusions:Non smokers aged 18 and above in Tianjin have a higher level of passive smoking exposure, and the awareness rate of tobacco exposure related cardiovascular diseases is low. In future, the health education of relevant knowledge should be strengthened.

Objective:To investigate the current status of endoscopic treatment for gastroesophageal varices in portal hypertension in China, and to provide supporting data and reference for the development of endoscopic treatment.Methods:In this study, initiated by the Liver Health Consortium in China (CHESS), a questionnaire was designed and distributed online to investigate the basic condition of endoscopic treatment for gastroesophageal varices in portal hypertension in 2022 in China. Questions included annual number and indication of endoscopic procedures, adherence to guideline for preventing esophagogastric variceal bleeding (EGVB), management and timing of emergent EGVB, management of gastric and isolated varices, and improvement of endoscopic treatment. Proportions of hospitals concerning therapeutic choices to all participant hospitals were calculated. Guideline adherence between secondary and tertiary hospitals were compared by using Chi-square test.Results:A total of 836 hospitals from 31 provinces (anotomous regions and municipalities) participated in the survey. According to the survey, the control of acute EGVB (49.3%, 412/836) and the prevention of recurrent bleeding (38.3%, 320/836) were major indications of endoscopic treatment. For primary [non-selective β-blocker (NSBB) or endoscopic therapies] and secondary prophylaxis (NSBB and endoscopic therapies) of EGVB, adherence to domestic guideline was 72.5% (606/836) and 39.2% (328/836), respectively. There were significant differences in the adherence between secondary and tertiary hospitals in primary prophylaxis of EGVB [71.0% (495/697) VS 79.9% (111/139), χ2=4.11, P=0.033] and secondary prophylaxis of EGVB [41.6% (290/697) VS 27.3% (38/139), χ2=9.31, P=0.002]. A total of 78.2% (654/836) hospitals preferred endoscopic therapies treating acute EGVB, and endoscopic therapy was more likely to be the first choice for treating acute EGVB in tertiary hospitals (82.6%, 576/697) than secondary hospitals [56.1% (78/139), χ2=46.33, P<0.001]. The optimal timing was usually within 12 hours (48.5%, 317/654) and 12-24 hours (36.9%, 241/654) after the bleeding. Regarding the management of gastroesophageal varices type 2 and isolated gastric varices type 1, most hospitals used cyanoacrylate injection in combination with sclerotherapy [48.2% (403/836) and 29.9% (250/836), respectively], but substantial proportions of hospitals preferred clip-assisted therapies [12.4% (104/836) and 26.4% (221/836), respectively]. Improving the skills of endoscopic doctors (84.2%, 704/836), and enhancing the precision of pre-procedure evaluation and quality of multidisciplinary team (78.9%, 660/836) were considered urgent needs in the development of endoscopic treatment. Conclusion:A variety of endoscopic treatments for gastroesophageal varices in portal hypertension are implemented nationwide. Participant hospitals are active to perform emergent endoscopy for acute EGVB, but are inadequate in following recommendations regarding primary and secondary prophylaxis of EGVB. Moreover, the selection of endoscopic procedures for gastric varices differs greatly among hospitals.
