Systemic lupus erythematosus （SLE）， a refractory autoimmune disease， is among the dominant diseases where traditional Chinese medicine （TCM） shows advantages in the field of rheumatology and immunology. The China-Japan Friendship Hospital hosted the "46^th Youth Salon on Dominant Diseases （Systemic Lupus Erythematosus）" organized by the China Association of Chinese Medicine， which led to a consensus on "the advantages， challenges， interdisciplinary approaches， and translational achievements of integrated TCM and Western medical approaches in the diagnosis and treatment of SLE." The diagnosis and treatment of SLE currently face several challenges， such as frequent misdiagnosis and missed diagnosis in the early stages， difficulty in achieving treatment targets， multiple side effects from pharmacotherapy， and the lack of management strategies for special populations， all of which hinder the fulfillment of the clinical needs of patients. Integrated TCM and Western medical approaches can improve clinical symptoms such as skin erythema， aversion to cold and cold limbs， fatigue， dry mouth， restlessness， and heat sensation in the palms and soles， thereby improving patients' quality of life. The approaches also help consolidate the efficacy of conventional Western medicine， slow disease progression， reduce relapse rates， address multi-organ involvement， and prevent or treat complications. Additionally， they enhance efficacy and reduce toxicity， prevent the side effects of Western medications， help reduce hormone use， and offer distinct advantages in the individualized intervention of special populations， contributing to the whole-process management of the disease. However， evidence-based medical support for this integrated approach remains limited， and the quality of available evidence is generally low. Common evaluation systems and modern research methodologies should be adopted to clarify the efficacy of TCM in SLE treatment. Efforts should be made to carry out high-quality evidence-based medical research， strengthen the development of fundamental and pharmacological research， and further explain the distinct advantages of TCM in the diagnosis and treatment of SLE. Future efforts should focus on advancing the integration of TCM and modern medicine， incorporating multi-omics technologies， individualized stratification， and other precision medicine concepts， in combination with artificial intelligence. Moreover， interdisciplinary collaboration should be promoted to utilize modern technology in exploring the essence of TCM theories and screening effective formulae， thereby comprehensively improving the diagnosis and treatment of SLE through integrated TCM and Western medical approaches.

ObjectiveTo study the clinical characteristics and influencing factors of rheumatoid arthritis （RA） in the patients with cold dampness obstruction syndrome. MethodsThe RA patients treated in the Department of Traditional Chinese Medicine and Rheumatology of the China-Japan Friendship Hospital from August 2022 to June 2024 were selected. The demographic information， clinical data， laboratory test results， and traditional Chinese medicine （TCM） symptom information were collected for syndrome differentiation， on the basis of which the characteristics and influencing factors of cold dampness obstruction syndrome were analyzed. ResultsA total of 258 RA patients were selected in this study， including 88 （34.1%） patients with cold dampness obstruction syndrome， 53 （20.5%） patients with dampness and heat obstruction syndrome， 31 （12.0%） patients with wind dampness obstruction syndrome， 29 （11.2%） patients with liver-kidney deficiency syndrome， 19 （7.4%） patients with Qi-blood deficiency syndrome， 14 （5.4%） patients with phlegm-stasis obstruction syndrome， 15 （5.8%） patients with stasis obstructing collateral syndrome and 9 （3.5%） patients with Qi-Yin deficiency syndrome. The patients were assigned into two groups of cold dampness obstruction syndrome and other syndromes. The group of cold dampness obstruction syndrome had lower joint fever， 28-tender joint count （TJC28）， and 28-joint disease activity score （DAS28）-C-reactive protein （CRP） and higher central sensitization， cold feeling of joints， fear of wind and cold， cold limbs， and abdominal distention than the group of other syndromes （P<0.05）. The binary logistic regression analysis showed that central sensitization （OR 5.749， 95%CI 2.116-15.616， P<0.001） and DAS28-CRP （OR 0.600， 95% CI 0.418-0.862， P=0.006） were the independent factors influencing cold dampness obstruction syndrome in RA. ConclusionCold dampness obstruction syndrome is a common syndrome in RA patients. It is associated with central sensitization， cold feeling of joints， abdominal distension and may be a clinical syndrome associated with central sensitization.

Background::Rapid initiation of antiretroviral therapy (ART) is recommended by guidelines, however, real-world studies of same-day initiation of ART in China are limited, and an optimal treatment regimen has yet to be identified. The study aims to provide a realistic reference for rapid initiation of ART.Methods::We retrospectively analyzed the clinical data of treatment-na?ve people with human immunodeficiency virus (PWHs) who were diagnosed and prescribed same-day ART initiation from January 1, 2021 to December 31, 2022 at Chongqing Public Health Medical Center. PWHs voluntarily chose an ART regimen that divided them into two groups: National Free Antiretroviral Treatment Program (NFATP)-recommended regimens group (2 nucleoside reverse transcriptase inhibitors + non-nucleoside reverse transcriptase inhibitors/protease inhibitors) and bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) group. The primary endpoint was the virological outcome of the two groups for same-day ART initiation at 24 weeks and 48 weeks. The secondary endpoints included changes in CD4 counts, maintenance of the original ART regimen at 48 weeks, and lipid levels and renal function at 48 weeks.Results::A total of 255 PWHs were included in the study, including 131 (51.4%) in the NFATP group and 124 (48.6%) in the BIC/FTC/TAF group. The overall virological suppression rates at 24 weeks and 48 weeks were 78.2% (165/211) and 95.4% (207/217), respectively. At 24 weeks, the virologic suppression rate in the NFATP group was lower than that in the BIC/FTC/TAF group (65.3% [66/101] vs. 90.0% [99/110], P <0.001). The median increase in the CD4 count was 198.0 (126.0-300.0) cells/μL at 24 weeks, with 182.0 (108.0-245.0) cells/μL in the NFATP group and 219 (132.0-316.0) cells/μL in the BIC/FTC/TAF group ( P = 0.035). At 48 weeks, there was no significant difference in the virological suppression rate or CD4 count between the groups. The 48-week initial ART regimen retention rates and treatment retention rates were significantly higher in the BIC/FTC/TAF group than in the NFATP group (91.1% (113/124) vs. 71.8% (94/131), 99.2% (118/119) vs. 93.0% (120/129), respectively). In terms of safety, there were no significant changes from baseline in levels of creatinine, estimated glomerular filtration rate (eGFR), or lipids in either group at 48 weeks. Conclusions::ART initiation on the day of diagnosis is effective, safe, and feasible, with satisfactory rates of virologic suppression, 48-week initial ART regimen retention rates, and treatment retention rates in treatment-na?ve PWHs. In our study, the early virologic suppression rate, CD4 cell counts, and treatment retention of the BIC/FTC/TAF regimens were significantly better than those of the NFATP regimens.

Objective To investigate the effect of trehalose(Tre)H9C2 cardiomyocytes under oxy-gen-glucose deprivation/reoxygenation(OGD/R)injury and its mechanism of action with the cel-lular model simulating the process of myocardial ischemia/reperfusion injury.Methods H9C2 cells were divided control group,OGD/R group,Tre group(OGD/R+Tre),and combination group(OGD/R+Tre+ML385).MTT assay was used to observe cell proliferation,and lactate de-hydrogenase(LDH)release and Hoechst/propidium iodide staining were employed to evaluate cell membrane damage.Western blot analysis was utilized to detect the expression of nuclear fac-tor erythroid 2-related factor 2(Nrf2)and its downstream related proteins.The generation of re-active oxygen species(ROS)and mitochondrial membrane potential(MMP)were measured to quantify the level of oxidative stress.The expression of apoptosis-related proteins was determined by Western blot analysis.Results In comparison to the control group,the OGD/R group exhibi-ted a significantly reduced cell viability.When compared with the OGD/R group,the intervention of varying concentrations of Tre obviously improved cell viability in a dose-dependent manner(P＜0.01),increased MMP,and up-regulated the expression of glutathione(GSH),Nrf2,hemeo-xygenase 1,and nicotinamide adenine dinucleotide phosphate quinone oxidoreductase 1(NQO1),Bcl-2,and cysteinyl aspartate specific proteinase 3(Caspase-3)(P＜0.05,P＜0.01),and decreased the production of ROS and MDA and the expression of responding element binding protein 1,Bax,Bax/Bcl-2,and cleaved Caspase-3(P＜0.05,P＜0.01).What's more,the combined group ex-hibited significantly higher production of ROS,MDA,increased mRNA levels of TNF-α,IL-1β,and IL-6,and reduced MMP and GSH levels(P＜0.05,P＜0.01),as well as,enhanced expression of Bax,Bax/Bcl-2,and cleaved Caspase-3(1.77±0.08 vs 1.20±0.20,3.41±1.45 vs 0.99±0.15,4.10±1.05 vs 1.79±0.52,P＜0.01),and decreased expression of Bcl-2 and Caspase-3(0.58±0.21 vs 1.23±0.25,0.87±0.25 vs 1.45±0.31,P＜0.01)in comparison with the Tre group.Conclusion Tre can be regarded as an Nrf2 activator that inhibits oxidative stress and apoptosis by activating Nrf2,and thereby ameliorates OGD/R-induced cardiomyocyte injury.

Objective:To evaluate the effect of trehalose on oxygen-glucose deprivation and restoration (OGD/R) injury in H9C2 cells and the role of solute carrier family 7 member 11- (SLC7A11)-glutathione peroxidase 4 (GPX4) signaling pathway.Methods:Well-grown H9C2 cells were divided into 4 groups ( n=24 each) by the random number table method: control group (group C), OGD/R group (group O), OGD/R+ trehalose group (group OT) and OGD/R+ trehalose+ erastin group (group OTE). The cells were normally cultured in group C. In O, OT and OTE groups, the DMEM medium was replaced with EBSS medium, the cells were exposed to 5% CO 2-95% N 2 in an incubator at 37 ℃ for 6 h, and then the medium was replaced with DMEM medium supplemented with 6% fetal bovine serum to restore oxygen and glucose supply for 24 h. In group OT, trehalose at a final concentration of 50 mmol/L was added during restoration of oxygen and glucose supply. In group OTE, the SLC7A11 inhibitor erastin at a final concentration of 10 μmol/L was added at 8 h before oxygen-glucose deprivation, and trehalose at a final concentration of 50 mmol/L was added during restoration of oxygen and glucose supply. The cell viability, lactic dehydrogenase (LDH) activity, contents of glutathione (GSH), malondialdehyde (MDA) and iron, and reactive oxygen species (ROS) levels were measured at 24 h of restoration of oxygen and glucose supply. The expression of SLC7A11, GPX4, long-chain fatty acyl coenzyme A synthetase 4 (ACSL4), and ferritin heavy chain 1 (FTH1) was detected by Western blot. The structure of the mitochondrial morphology was observed with a transmission electron microscope. Results:Compared with group C, the cell viability and GSH content were significantly decreased, the LDH activity, contents of MDA and iron, and ROS level were increased, the expression of SLC7A11, GPX4 and FTH1 was down-regulated, and the expression of ACSL4 was up-regulated in group O ( P<0.05). Compared with group O, the cell viability and GSH content were significantly increased, the LDH activity, contents of MDA and iron, and ROS level were decreased, the expression of SLC7A11, GPX4 and FTH1 was up-regulated, and the expression of ACSL4 was down-regulated in group OT ( P<0.05). Compared with group OT, the cell viability and GSH content were significantly decreased, the LDH activity, contents of MDA and iron, and ROS levels were increased, the expression of SLC7A11, GPX4 and FTH1 was down-regulated, and the expression of ACSL4 was up-regulated in group OTE ( P<0.05). Conclusions:Trehalose can inhibit ferroptosis by activating the SLC7A11-GPX4 signaling pathway, thereby attenuating OGD/R injury in H9C2 cells.

Objective To investigate the occurrence of intraoperative frozen section(FS)pathology unclear diagnosis in thyroid carcinoma,seeking clinical factors affecting the pathological accuracy of FS.Methods Retrospective analysis of thyroid cancer patients who underwent surgical treatment at People's Hospital of Daxing District in Beijing from August 2016 to December 2019.Target nodules were divided into FS clear diagnosis group and unclear diagnosis group(including delayed diagnosis group,misdiagnosis group,accidental diagnosis group)according to the results of FS and paraffin section pathological examination.The general information,laboratory test,result of color ultrasound and pathological types between FS clear diagnosis group and unclear diagnosis group were compared.Results A total of 336 cancer nodules were included.The quantity and proportion of cancer nodules in clear diagnosis group,delayed diagnosis group,misdiagnosis group and accidental diagnosis group were respectively 266(79.17%),28(8.33%),21(6.25%)and 21(6.25%).In the delayed diagnosis group,"no exception"thyroid cancer was the most frequently used.Compared to clear diagnosis group,the maximum diameter of cancer nodules in delayed diagnosis group,misdiagnosis group,accidental diagnosis group were smaller(P<0.05);In the delayed diagnosis group,the proportion of aspect ratio>1 was higher(P=0.017),and the proportion of microcalification was lower(P=0.002).In the misdiagnosis group,thyroid peroxidase antibody level was higher(P=0.002).Conclusion Clinical doctors should be familiar with commonly used diagnostic terms for delayed diagnosis and misdiagnosis.When making treatment decisions,full consideration should be given to the possibility of difficult to diagnose diagnosis,especially for patients with small nodules and concurrent chronic lymphocytic thyroiditis.

Objective:To develop a U-Net-based quadruple numerical neural network (QU-Net) model for retinal vessel segmentation and to verify its precision and efficiency in extracting and segmenting retinal vessels from fundus images.Methods:This study used the concept of hypercomplex numbers, the three channels of color images, and a quaternion matrix representing all the information data of the images, which was then used as input for quaternion convolution and quaternion fully connected layers based on the U-Net architecture to form a QU-Net model.The QU-Net model was first tested on the DRIVE, STARE, and CHASE_DB1 datasets and compared with the traditional real-valued U-Net, M-Net, and SU-Net models in terms of accuracy, sensitivity, specificity, precision, F1 score, and Matthews correlation coefficient.Finally, the model was further optimized and the optimized QU-Net model was compared side-by-side with the well-known advanced models to comprehensively evaluate and analyze the efficiency and accuracy of the model in extracting and segmenting retinal blood vessels from fundus images.Results:The results showed that the QU-Net model achieved the following vessel segmentation results: accuracy 0.956 6, sensitivity 0.700 8, specificity 0.987 9, precision 0.595 4 on the DRIVE dataset, accuracy 0.975 5, sensitivity 0.890 7, specificity 0.984 2, precision 0.662 5 on the STARE dataset, and accuracy 0.979 4, sensitivity 0.747 0, specificity 0.990 6, precision 0.596 9 on the CHASE_DB1 dataset.Its specificity was better than U-Net, M-Net and SU-Net models, and its accuracy, sensitivity and precision were not inferior to the three models.After optimization, the sensitivity, precision and F1 value of the QU-Net model were effectively improved on the three datasets while maintaining its original accuracy and specificity.When compared with the performance indicators of other models on the three datasets, it was found that the optimized QU-Net model had good performance in accuracy, specificity, sensitivity, precision, and F1 score, indicating that its vessel segmentation ability was not inferior to the advanced models.Among all the models compared, the optimized QU-Net model had the best F1 score and Matthews correlation coefficient.Conclusions:The QU-Net model proposed in this study expands the data dimension space from the traditional real number space to the complex number space and greatly reduces the loss of data information.The optimized QU-Net model has good efficiency and accuracy in extracting retinal vessel segmentation from fundus images, and has certain advantages in detecting fine vessels.

BACKGROUND:Stage Ⅲ Kümmell's disease is characterized by a high degree of vertebral compression and posterior wall defects.Most of the patients are elderly people with severe osteoporosis and various medical diseases.Clinically,some surgical methods are often at high risk and are controversial. OBJECTIVE:To investigate the clinical efficacy of screw placement combined with transpedicular impaction bone grafting in the treatment of stage Ⅲ Kümmell's disease. METHODS:The clinical data of injured vertebral screw placement combined with transpedicular impaction bone grafting in treatment of stage Ⅲ Kummell's disease from May 2016 to August 2021 were retrospectively analyzed.Visual analog scale score,Oswestry disability index,anterior vertebral heights,kyphotic Cobb angle and American Spinal Injury Association(ASIA)impairment scale were used to evaluate the effects of surgery.The operation time,intraoperative blood loss and complications were recorded.CT scans were used to evaluate the healing of injured vertebrae at the final follow-up visit. RESULTS AND CONCLUSION:(1)A total of 26 patients were included,with 7 males and 19 females,at the age range of 62-81 years[mean(69.7±4.8)years].The follow-up time was 18-60 months[mean(35.1±8.9)months].The average operative duration was 133.5 minutes(100-165 minutes),and the average intraoperative blood loss was 285.3 mL(210-350 mL).(2)Visual analog scale and Oswestry disability index scores 1 week after surgery were significantly lower than those before surgery.(3)At 1 week after surgery,the anterior vertebral height corrections and the Cobb angle were(9.0±0.7)mm and(16.2±1.0)°,respectively.During the follow-up period,the loss of vertebral height and kyphosis correction were(5.1±0.3)mm and(8.0±0.4)°,respectively.(4)14 patients(54%)had ASIA grade D before operation,which recovered to grade E at the last follow-up.CT scan showed that all patients achieved good osseous union.(5)Complications occurred in seven patients(27%),including hypostatic pneumonia in two cases,postoperative superficial wound tissue liquefaction in two cases,and adjacent vertebral compression fractures in three cases.(6)It is concluded that screw placement of the injured vertebra combined with transpedicular impaction bone grafting can rapidly rebuild spinal stability,effectively relieve pain and improve neurological function in the treatment of stage Ⅲ Kümmell's disease.This technique is an effective and relatively minimally invasive surgical option.
