BackgroundNegative symptoms of schizophrenia impose a substantial burden on society， and the current antipsychotic drugs have limited efficacy in treating these symptoms. Intermittent theta burst stimulation （iTBS）， as a novel neuromodulation technique， shows potential therapeutic promise. However， the evidence for its efficacy in treating negative symptoms of schizophrenia and its relationship with associated immuno-inflammatory changes remain to be further elucidated. ObjectiveTo investigate the efficacy of iTBS targeting the left dorsolateral prefrontal cortex （L-DLPFC） on persistent negative symptoms of schizophrenia， and to analyze its relationship with changes in peripheral blood inflammatory markers， so as to provide references for the clinical application of iTBS in treating persistent negative symptoms and to offer clues for further research into its potential biological mechanisms. MethodsA randomized， double-blind， sham-controlled clinical trial was conducted. A total of 60 patients with schizophrenia who were hospitalized at Xuzhou Oriental Peopple's Hospital from February 20， 2024 to May 10， 2025 were consecutively enrolled. All patients met the diagnostic criteria for schizophrenia according to the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） and fulfilled the criteria for persistent negative symptoms. Participants were randomly assigned into the study group and the control group， with 30 patients in each group. The two groups respectively received 20 sessions of either active iTBS or sham stimulation over a 4-week period. Clinical symptoms were assessed using the Positive and Negative Syndrome Scale （PANSS） at the baseline， the end of treatment， and 3 months after treatment. Peripheral blood inflammatory markers were measured at the baseline and at the end of treatment， including white blood cell count， platelet count， neutrophil count， lymphocyte count， and monocyte count， the neutrophil-to-lymphocyte ratio （NLR）， monocyte-to-lymphocyte ratio （MLR）， and platelet-to-lymphocyte ratio （PLR） were also calculated. A linear mixed model was used to compare PANSS scores between the two groups. Spearman correlation analysis was performed to examine the association between reductions in inflammatory markers at the end of treatment and reductions in PANSS negative symptom subscale scores， with body mass index （BMI） and chlorpromazine-equivalent dose as covariates. Results①The time-group interaction effect for the PANSS negative symptom subscale score was statistically significant （F=5.410， P<0.01）. At the end of treatment and 3 months after treatment， the study group had significantly lower scores on the PANSS negative symptom subscale than the control group （P<0.01）. ② At the end of treatment， group differences in reduction scores for neutrophil count， NLR， and PLR were significant （Z=-2.262， -2.048， -2.070， P<0.05）. However， after FDR correction， the between-group differences in reductions in peripheral blood inflammatory markers were no longer statistically significant （P>0.05）. ③ After adjusting for BMI and chlorpromazine equivalents， the reduction in PANSS negative symptom subscale scores was positively correlated with the reduction in neutrophil count in the study group （r_s=0.382， P=0.045）. ConclusioniTBS targeting the L-DLPFC may be beneficial in improving persistent negative symptoms of schizophrenia， and its clinical efficacy may be associated with changes in neutrophil count. ［Funded by National Natural Science Foundation of China （number， 82371510）； Social Development Project of Jiangsu Province （number， BE2023668）. www.chictr.org.cn number， ChiCTR2500101060］

As an important endocrine organ of human body,adipose tissue secrets a large amount of endocrine fac-tors that regulate a variety of physiological functions,and role of adiponectin in cardiovascular system is especially important.At the cellular and molecular level,adiponectin possesses profound anti-inflammatory,anti-oxidative and anti-apoptotic effects,which can reduce various pathogenic factors of cardiovascular diseases(CVD).In ad-vanced stage of CVD,the expression of adiponectin in adipose tissue as well as its circulating level compensatively increased.Therefore,adiponectin has a protective effect on the cardiovascular system,and increased adiponectin level may suggest severe CVD.In this review article,we systematically introduced the role of adiponectin in CVD and discussed its application prospects as a clinical biomarker.

Endosomes are characterized by the presence of various phosphoinositides that are essential for defining the membrane properties. However, the interplay between endosomal phosphoinositides metabolism and innate immunity is yet to be fully understood. Here, our findings highlight the evolutionary continuity of RAB-10/Rab10's involvement in regulating innate immunity. Upon infection of Caenorhabditis elegans with Pseudomonas aeruginosa, an increase in RAB-10 activity was observed in the intestine. Conversely, when RAB-10 was absent, the intestinal diacylglycerols (DAGs) decreased, and the animal's response to the pathogen was impaired. Further research revealed that UNC-16/JIP3 acts as an RAB-10 effector, facilitating the recruitment of phospholipase EGL-8 to endosomes. This leads to a decrease in endosomal phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2) and an elevation of DAGs, as well as the activation of the PMK-1/p38 MAPK innate immune pathway. It is noteworthy that the dimerization of UNC-16 is a prerequisite for its interaction with RAB-10(GTP) and the recruitment of EGL-8. Moreover, we ascertained that the rise in RAB-10 activity, due to infection, was attributed to the augmented expression of LET-413/Erbin, and the nuclear receptor NHR-25/NR5A1/2 was determined to be indispensable for this increase. Hence, this study illuminates the significance of endosomal PI(4,5)P2 catabolism in boosting innate immunity and outlines an NHR-25-mediated mechanism for pathogen detection in intestinal epithelia.

This paper aimed to explore the effects of Duzhong Decoction(DZD)-containing serum on the proliferation and osteoblast differentiation of MC3T3-E1 cells through L-type voltage-gated calcium channels(L-VGCCs). L-VGCCs inhibitors, nifedipine and verapamil, were used to block L-VGCCs in osteoblasts. MC3T3-E1 cells were divided into a control group, a low-dose DZD-containing serum(L-DZD) group, a medium-dose DZD-containing serum(M-DZD) group, a high-dose DZD-containing serum(H-DZD) group, a nifedipine group, a H-DZD + nifedipine group, verapamil group, and a H-DZD + verapamil group. The CCK-8 method was used for cell proliferation analysis, alkaline phosphatase(ALP) assay kits for intracellular ALP activity measurement, Western blot for protein expression level in cells, real-time fluorescence quantitative PCR technology for intracellular mRNA expression level determination, fluorescence spectrophotometer for free Ca~(2+) concentration determination in osteoblasts, and alizarin red staining(ARS) for mineralized nodule formation in osteoblasts. The experimental results show that compared to the control group, DZD groups can promote MC3T3-E1 cell proliferation, ALP activity, and mineralized nodule formation, increase intracellular Ca~(2+) concentrations, and upregulate the protein expression of bone morphogenetic protein 2(BMP2), collagen Ⅰ(COL1), α2 subunit protein of L-VGCCs(L-VGCCα2), and the mRNA expression of Runt-related transcription factor 2(RUNX2), and BMP2. After blocking L-VGCCs with nifedipine and verapamil, the intervention effects of DZD-containing serum were inhibited to varying degrees. Both nifedipine and verapamil could inhibit ALP activity, reduce mineralized nodule areas, and downregulate the expression of bone formation-related proteins. Moreover, the effects of DZD-containing serum on increasing MC3T3-E1 cell proliferation, osteoblast differentiation, and Ca~(2+) concentrations, upregulating the mRNA expression of osteoprotegerin(OPG) and protein expression of phosphorylated protein kinase B(p-Akt) and phosphorylated forkhead box protein O1(p-FOXO1), and upregulating phosphatase and tensin homolog(PTEN) expression were reversed by nifedipine. The results indicate that DZD-containing serum can increase the Ca~(2+) concentration in MC3T3-E1 cells to promote bone formation, which may be mediated by L-VGCCs and the PTEN/Akt/FoxO1 signaling pathway, providing a new perspective on the mechanism of DZD in treating osteoporosis.

BACKGROUND: Disease-modifying therapies have been approved for the treatment of relapsing multiple sclerosis (RMS). The present study aims to examine the safety of teriflunomide in Chinese patients with RMS. METHODS: This non-randomized, multi-center, 24-week, prospective study enrolled RMS patients with variant (c.421C>A) or wild type ABCG2 who received once-daily oral teriflunomide 14 mg. The primary endpoint was the relationship between ABCG2 polymorphisms and teriflunomide exposure over 24 weeks. Safety was assessed over the 24-week treatment with teriflunomide. RESULTS: Eighty-two patients were assigned to variant ( n  = 42) and wild type groups ( n  = 40), respectively. Geometric mean and geometric standard deviation (SD) of pre-dose concentration (variant, 54.9 [38.0] μg/mL; wild type, 49.1 [32.0] μg/mL) and area under plasma concentration-time curve over a dosing interval (AUC tau ) (variant, 1731.3 [769.0] μg∙h/mL; wild type, 1564.5 [1053.0] μg∙h/mL) values at steady state were approximately similar between the two groups. Safety profile was similar and well tolerated across variant and wild type groups in terms of rates of treatment emergent adverse events (TEAE), treatment-related TEAE, grade ≥3 TEAE, and serious adverse events (AEs). No new specific safety concerns or deaths were reported in the study. CONCLUSION: ABCG2 polymorphisms did not affect the steady-state exposure of teriflunomide, suggesting a similar efficacy and safety profile between variant and wild type RMS patients.
