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.

Objective To compare the long-term prognosis of elderly patients with stageⅠnon-small cell lung cancer (NSCLC) after lobectomy or segmentectomy. Methods Data of elderly patients with stageⅠNSCLC between 2010 and 2020 were collected from the SEER database. According to the resection method, patients were divided into a lobectomy group and a segmentectomy group. The overall survival (OS) and lung cancer-specific survival (LCSS) of the two groups were compared by propensity score matching (lobectomy : segmentectomy=2 : 1). Results A total of 9990 patients were included, including 5840 (58.46%) females and 4150 (41.54%) males, with an average age of (70.48±6.47) years. Among them, 9029 patients were in the lobectomy group and 961 patients were in the segmentectomy group. After propensity score matching, a total of 2883 patients were matched, including 1 922 patients in the lobectomy group and 961 patients in the segmentectomy group. There was no statistical difference in baseline data between the two groups (P>0.05). The 10-year OS rate and LCSS rate of the lobectomy group were higher than those of the segmentectomy group (OS: 51.15% vs. 38.35%, P<0.01; LCSS: 79.68% vs. 71.52%, P<0.01). Subgroup analysis showed that the survival advantage of lobectomy was found in patients aged 60-<70 years and ≥80 years; for patients 70-<80 years, there was no statistical difference in OS or LCSS between the two surgical methods (P>0.05). In addition, for patients with tumor diameter ≤2 cm (stages ⅠA1-ⅠA2), lymph node dissection number≥10, and receiving adjuvant radiotherapy/chemotherapy, segmentectomy could also achieve a similar prognosis as lobectomy. Conclusion Overall, for elderly patients with stage ⅠNSCLC, lobectomy can achieve better OS and LCSS. However, individual differences, tumor characteristics, and perioperative treatment plans should be considered comprehensively to determine the surgical method for elderly patients with stageⅠNSCLC.

Octapeptin has strong antibacterial activity against Gram-negative bacteria such as Escherichia coli, Klebsiella pneumoniae and Acinetobacter baumannii, while it also has activity against some Gram-positive bacteria. This study used natural octapeptin A3 and B3 as lead compounds for structural modification. Twenty-one peptide derivatives (including A3 and B3) containing eight amino acid residues were prepared by solid-phase synthesis, and evaluated for antibacterial activity and renal cytotoxicity. Among them, three compounds 6, 7 and 17 exhibited broad-spectrum antibacterial activity and significantly enhanced the activity for Gram-positive bacteria while maintaining the activity of Gram-negative bacteria. Several compounds improved the activity for Pseudomonas aeruginosa. Compound 7 was active against all test strains and had relatively low renal cytotoxicity. The results provide a basis for the further development of novel polypeptide antibiotics.

Objective:This study aimed to explore the performance of renal resistive index (RRI), semiquantitative power Doppler ultrasound (PDU) score, and renal venous Doppler waveform (RVDW) pattern in predicting 28-day renal dysfunction in critically ill patients and establish nomogram model.Methods:This was a prospective, observational study. Critically ill patients admitted to the emergency intensive care unit (ICU) of Cangzhou Central Hospital from January 2018 to October 2022 were included. Patients underwent renal ultrasound examination to obtain RRI, PDU score and RVDW pattern within 24 h after ICU admission. The following clinical variables were collected during the renal ultrasound examination session, including heart rate, mean arterial pressure, type and dose of vasoactive drugs, oxygen therapy parameters, and average urine volume per hour derived from a period of 6 h prior to the ultrasound examination. The data on duration of AKI and mortality were recorded on the 28th day of follow-up. Patients were divided into 28-day normal renal function group and 28-day renal dysfunction group according to 28-day renal dysfunction. 28-days of renal dysfunction was defined as failure to achieve renal function recovery within 28 days of ICU admission. The difference of each index between the two groups was compared. Associated factors for 28-day renal dysfunction were determined by univariate and multivariate COX regression analyses. A nomogram was developed based on the independently factors associated with 28-day renal dysfunction. Survival receiver operator characteristic (ROC) curves were plotted to assess diagnostic performance in predicting 28-day renal dysfunction. Delong’s test was used to compare area under the curves (AUC) between each predictor.Results:187 patients were enrolled for the final analysis: 97 with no AKI, 48 with AKI stage 1, 24 with AKI stage 2, and 18 with AKI stage 3 upon enrollment. At 28-day follow up, 16 patients had renal dysfunction and 2 required continuous renal replacement therapy (CRRT). The multivariate COX regression showed that RVDW and SCr upon enrollment were the independent risk predictors. Nomogram based on RVDW and SCr upon enrollment showed the best performance in predicting 14-day renal dysfunction (AUC = 0.918, 95% CI:0.871-0.964, P<0.05), and the AUC was statistically significantly higher than single index (all P<0.05). Nomogram also showed the best performance in predicting 28-day renal dysfunction (AUC = 0.924, 95% CI:0.865-0.983, P<0.05), and the AUC was statistically significantly higher than single index (all P<0.05) except for SCr upon enrollment. The optimal cutoff for nomogram in predicting 28-day renal dysfunction was ≤89.5 (sensitivity, 81.2%; specificity, 90.6%; Youden index, 0.719). Kaplan-Meier analysis showed that the median duration of renal dysfunction in the groups with total nomogram score >85.9 and ≤85.9 was 0 and 22 days (HR=0.220, 95% CI:0.129-0.376, P<0.001). Conclusions:SCr and RVDW pattern within 24 h from ICU admission were independent factors associated with 28-day renal dysfunction in critically ill patients. The value of the nomogram model based on these two factors in predicting 28-day renal dysfunction is superior to each single intrarenal Doppler spectrum indicator and clinical indicator.

Objective To explore the effect of chemotherapeutic drugs doxorubicin or cisplatin on lipid metabolism of macrophages and its regulatory mechanism.Methods Macrophage RAW264.7 was treated with doxorubicin or cisplatin,and intracellular lipid level was detected by oil red O and ELISA;RNA sequence screen-ing and Western blot were used to confirm the changes of gene expression after chemotherapeutic drug treatment;The effects of silencing ROBO3 on cellular lipid metabolism were explored,and changes in key target genes of lipid metabolism were detected by Q-PCR and western blot.Results Adriamycin or cisplatin induced disturbances in macrophage cholesterol metabolism and exacerbated macrophage foaminess.Further studies showed that the expression of the axon guidance factor receptor,ROBO3,increased and then decreased during the chemotherapeutic drug-induced macrophage foaming process.Further intervention with ROBO3 exacerbates oxldl-induced cholesterol accumulation and foam formation in macrophages.Mechanistically,ROBO3 deficiency promotes the expression of cholesterol synthesis-related gene DHCR24 and inhibits the expression of cholesterol elimination-related gene ABCG1,resulting in cholesterol accumulation in macrophages.Conclusion This study found that ROBO3 plays an important regulatory role in the disruption of cholesterol metabolism and its foaming process in macrophages induced by chemotherapeutic drugs,which may provide new targets and ideas for the prevention and treatment of chemotherapy-related atherosclerosis.

BACKGROUND:It is known that N6-methyladenosine(m6A)plays a role in the pathogenesis of various diseases and studies have suggested its involvement in the pathologic changes of steroid-induced femoral head necrosis(SNFH).However,research on m6A methylation modifications in steroid-induced femoral head necrosis is limited. OBJECTIVE:Using bioinformatics methods to identify the differential expression of m6A-related genes in steroid-induced femoral head necrosis and to predict miRNAs associated with these genes to further elucidate the role and mechanism of m6A methylation in steroid-induced femoral head necrosis. METHODS:Differential gene expression between steroid-induced femoral head necrosis and control groups was analyzed using GSE123568 gene expression data and identified using the"limma"package in R.Functional enrichment analysis was performed on the differentially expressed genes.Differential analysis of the related genes was carried out using the"ggstatsplot"package in R.The differential genes were cross-validated using the GSE74089 dataset.An mRNA-miRNA regulatory network was constructed,and co-expression analysis was performed on the module genes followed by enrichment analysis.Differences in immune cell infiltration between steroid-induced femoral head necrosis and control groups were quantified using the ssGSEA method. RESULTS AND CONCLUSION:Correlation analysis revealed 13 m6A-related genes,and further analysis through the protein-protein interaction network identification and receiver operating characteristic curve analysis showed that YTHDF2 was expected to be a core differential gene as a potential early biomarker.Enrichment analysis indicated that differentially expressed genes were mainly involved in inflammation and immune response and were closely related to osteoclasts.Cross-validation analysis showed that differential gene expression results between the two datasets were consistent.mRNA-miRNA regulatory network analysis revealed that YTHDF2 was negatively correlated with miRNA-27a.Immune infiltration analysis revealed an increase in immune cell infiltration in steroid-induced femoral head necrosis,and YTHDF2 was positively correlated with the infiltration of CD4+T cells.To conclude,m6A-related gene YTHDF2 can serve as a potential biomarker of steroid-induced femoral head necrosis and is valuable for the early clinical diagnosis and treatment of steroid-induced femoral head necrosis.The negative correlation between YTHDF2 and mir-27a and the positive correlation between YTHDF2 and CD4+T cell infiltration provide new insights into the early diagnosis and treatment of steroid-induced femoral head necrosis and shed light on the mechanism of m6A in steroid-induced femoral head necrosis.

Objective:To explore the effects of Liuwei Dihuang Wan on the behaviors and Toll-like receptor 4/nuclear factor kappa-B(TLR4/NF-κB) signal transduction pathway of amyloid β-precursor protein/presenilin-1(APP/PS1) double transgenic mice.Methods:Forty 3-month-old female APP/PS1 mice were randomly divided into model group, low-dose group(0.59 g/kg), medium-dose group(1.18 g/kg), high-dose group(2.36 g/kg)of Liuwei Dihuang Wan(gavaged according to grouped doses), and ibuprofen group(0.04 g/kg, gavage) using a random number table method, with 8 mice in each group.Eight 3-month-old wild-type female C57BL/6 mice with matched body weight were used as the control group.The mice in control group and model group were given an equal volume of 0.9% sodium chloride solution by gavage.The gavage administration was twice a day for a continuous period of 3 months.Morris water maze test was used to detect the learning and memory abilities of mice. ELISA was used to detect the serum levels of tumor necrosis factor-α (TNF-α), interleukin-1β(IL-1β) and immunohistochemistry was used to detect the levels of amyloid β-protein (Aβ), glial fibrillary acidic protein(GFAP) and NF-κB in hippocampal tissue.Western blot was used to detect the expression levels of TLR4, myeloid differentiation primary response gene 88(MyD88), and phosphorylated NF-κB(p-NF-κB) proteins in hippocampal tissue.The SPSS 20.0 software was used for data analysis. Multiple group comparisons were conducted by repeated measure ANOVA or one-way ANOVA.Results:The results of repeated measure ANOVA showed that as for the escape latency of the 6 groups of mice, the interaction effect between time and group was significant ( Finteraction=117.219, P<0.001). The escape latencies of mice in the 6 groups on the 5th day were all lower than those on the 1st day (all P<0.05). The escape latencies of mice in the ibuprofen group and the medium-dose and high-dose groups of Liuwei Dihuang Wan were lower than that in the model group from 1st day to 5th day(all P<0.05). On the 3rd to 5th day, the escape latencies of mice in the medium-dose and high-dose groups of Liuwei Dihuang Wan were lower than those in the low-dose group of Liuwei Dihuang Wan (all P<0.05). There were statistically significant differences in the percentage of residence time in the platform quadrant and the numbers of crossing platform among the 6 groups of mice ( F=5.451, 4.824, both P<0.05). The percentage of residence time in the platform quadrant (50.77±5.49)%, (54.39±5.71)%, (51.98±6.12)%), and the numbers of crossing platform((5.9±1.1) times, (6.0±1.3) times, (5.1±0.8) times) in the high-dose and medium-dose groups of Liuwei Dihuang Wan and the ibuprofen group were all higher than those in the model group ((27.32±3.22)%, (2.2±1.0) times )(all P<0.05). The immunohistochemical results showed that there were statistically significant differences in the integrated optical density values of Aβ, GFAP and NF-κB in the hippocampal tissues of 6 groups of mice ( F=57.52, 45.37, 79.10, all P<0.05). The integrated optical density values of Aβ, GFAP and NF-κB in the high-dose and medium-dose groups of Liuwei Dihuang Wan and the ibuprofen group were all lower than those in the model group (all P<0.05). And the integrated optical density values of Aβ, GFAP, and NF-κB in the high-dose and medium-dose groups of Liuwei Dihuang Wan were all lower than those in the low-dose group of Liuwei Dihuang Wan (all P<0.05). There were statistically significant differences in the levels of serum TNF-α and IL-1β detected by ELISA ( F=3.996, 6.395, both P<0.05) and the proteins levels of TLR4, MyD88, and p-NF-κB in hippocampal tissue detected by Western blot among the 6 groups( F=15.710, 3.522, 4.119, all P<0.05). The serum TNF-α and IL-1β levels in the high-dose and medium-dose groups of Liuwei Dihuang Wan and ibuprofen group were all lower than those in the model group (all P<0.05). The serum TNF-α ((18.90±2.33) ng/L, (21.56±2.49) ng/L) and IL-1β ((5.88±0.80) ng/L, (6.75±0.83) ng/L) levels in the high-dose and medium-dose groups of Liuwei Dihuang Wan were lower than those in the low-dose group ((30.77±2.89) ng/L, (9.11±1.27) ng/L) (all P<0.05). The protein expression levels of TLR4, MyD88, and p-NF-κB in the hippocampus of the high-dose and medium-dose groups of Liuwei Dihuang Wan and ibuprofen group were lower than those of the model group (all P<0.05). The protein expression levels of TLR4 ((0.254±0.091), (0.318±0.122)), MyD88 ((0.229±0.077), (0.386±0.119)), and p-NF-κB ((0.412±0.188), (0.358±0.119)) in the hippocampus of the high-dose and medium-dose groups of Liuwei Dihuang Wan were lower than those of the low-dose group ((0.617±0.172), (0.672±0.166), (0.799±0.227)) (all P<0.05). Conclusion:Liuwei Dihuang Wan can significantly alleviate learning and memory impairment in Alzheimer's disease model mice, possibly by inhibiting TLR4/NF-κB signal pathway, reducing TNF-α and IL-1β expression, thereby alleviate central immune inflammatory response and exert anti Alzheimer's disease effects.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Objective:To explore the prognostic value of baseline 18F-FDG PET/CT metabolic parameters in locally advanced cervical cancer (LACC) after concurrent chemoradiotherapy (CCRT). Methods:From September 2015 to October 2021, the clinical data of 180 LACC patients (age: 22-76 years) who underwent 18F-FDG PET/CT before CCRT at Affiliated Cancer Hospital of Shandong First Medical University were analyzed retrospectively. The metabolic tumor volume (MTV), total lesion glycolysis (TLG), SUV max, and SUV mean were computed by using the margin threshold of 42%SUV max. The optimal threshold for predicting progression-free survival (PFS) was obtained by ROC curve analysis. The Kaplan-Meier method was applied for survival analysis, and the log-rank test was applied to compare the survival rate between groups. Multivariate Cox proportional hazard regression was used to analyze progression for PFS. Results:The median follow-up was 19.1 months, and 54 patients (30.0%, 54/180) suffered from disease progression. ROC curve analysis showed that the optimal cut-off value of MTV was 31.145 ml, with the AUC of 0.641. Para-aortic lymph node (PALN) metastasis had the highest AUC value (0.589) among the clinical factors, followed by International Federation of Gynecology and Obstetrics (FIGO) stage (0.581). The 1-year PFS rates of patients with MTV<31.145 ml ( n=88) and MTV≥31.145 ml ( n=92) were 80.68% and 59.78%, respectively ( χ2=13.72, P<0.001). Multivariate Cox analysis demonstrated that pathological type (hazard ratio ( HR)=3.075, 95% CI: 1.370-6.901, P=0.006), FIGO stage ( HR=1.955, 95% CI: 1.031-3.707, P=0.040), PALN metastasis ( HR=2.136, 95% CI: 1.202-3.796, P=0.010) and MTV ( HR=2.449, 95% CI: 1.341-4.471, P=0.004) were the significant predictors for PFS. Conclusions:Pathological type, FIGO stage, PALN metastasis and MTV are independent prognostic risk factors for PFS. MTV as the baseline 18F-FDG PET/CT metabolic parameter, can realize prognostic stratification analysis.
