AIM:To investigate the expression levels of serum sirtuin 6(Sirt6)and nicotinamide adenine dinucleotide phosphate oxidase 2(NOX2)in patients with primary glaucoma and their correlation with the severity of the disease. METHODS:This study is a cross-sectional study. Patients diagnosed with primary glaucoma at the hospital from August 2022 to June 2025 were enrolled and divided into mild-to-moderate and severe groups based on the mean deviation of visual field defects, along with healthy individuals as a control group. Clinical data were collected, and serum levels of Sirt6 and NOX2 were measured using enzyme-linked immunosorbent assay(ELISA). Correlations between serum Sirt6 and NOX2 levels and clinical parameters were analyzed. Multivariate Logistic regression was used to identify factors influencing disease severity, and the diagnostic efficacy of serum Sirt6 and NOX2 levels was evaluated using receiver operating characteristic(ROC)curves. RESULTS:A total of 120 patients with primary glaucoma(58 males, 62 females, mean age 60.08±8.19 y)and 100 controls(46 males, 56 females, mean age 60.23±8.67 y)were enrolled in this study. There were no statistically significant differences in sex or age between the two groups(both P>0.05). The intraocular pressure and serum NOX2 expression level in the primary glaucoma group were significantly higher than those in the control group, while the Sirt6 level was significantly lower than in the control group(all P<0.001). The AUC values of serum Sirt6 and NOX2 in the diagnosis of primary glaucoma were 0.733 and 0.770, respectively, with optimal cutoff values of 2.35 and 4.25 ng/mL, respectively. The AUC of the combined diagnosis of the two was 0.901, and its efficacy was obviously better than that of a single indicator(Zcombination-Sirt6=5.317, Zcombination-NOX2=4.720, P<0.001).The severe group had lower serum Sirt6 expression levels(P<0.05), and higher NOX2 expression levels(P<0.05)than the mild-to-moderate group. Serum Sirt6 expression levels were prominently negatively correlated with mean intraocular pressure(r=-0.354, P<0.05); NOX2 expression levels were prominently positively correlated with mean intraocular pressure(r=0.240, P<0.05). Multivariate Logistic regression analysis showed that a decrease in serum Sirt6 expression levels(OR=0.229, 95%CI: 0.090-0.581), an increase in serum NOX2 expression levels(OR=2.649, 95%CI: 1.658-4.232), an increase in mean intraocular pressure(OR=1.278, 95%CI: 1.118-1.462)which were risk factors for the progression to severe glaucoma. The AUC values of serums Sirt6 and NOX2 expression levels in diagnosing severe primary glaucoma were 0.794 and 0.800, respectively, the AUC, sensitivity, and specificity of the combined diagnosis of the two were 0.916, 80.00%, and 89.33%, respectively, and the combined diagnostic efficacy was better than that of a single indicator(Zcombination-Sirt6=2.627, P=0.009, Zcombination-NOX2=2.762, P=0.006). CONCLUSION:The decreased serum Sirt6 and increased NOX2 expression levels in patients with primary glaucoma are significantly correlated with disease severity, and the combined detection demonstrates good diagnostic value for primary glaucoma and its severity.

ObjectiveTo investigate the mechanisms by which Renshentang treats atherosclerosis (AS) in mice, focusing on the regulation of endothelial inflammatory responses mediated by transient receptor potential vanilloid subtype 1 (TRPV1). MethodsAn AS model was established in apolipoprotein E knockout (ApoE-/-) mice fed a high-fat diet. The mice were randomly divided into a simvastatin group (0.02 g·kg-1·d-1) and low-, medium-, and high-dose Renshentang groups (1.77, 3.54, 7.08 g·kg-1·d-1), with 12 mice in each group. ApoE-/- mice were fed a high-fat diet and treated simultaneously. C57BL/6J mice fed a normal diet served as the normal group (n=9). After continuous administration for 12 weeks, mice were anesthetized and the aortas were collected. Oil Red O staining was used to observe lipid plaque formation in the aorta. Hematoxylin-eosin (HE) staining was performed to examine pathological changes in the aortic root. Immunohistochemistry was used to analyze the levels of pro-inflammatory factors tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β), as well as the expression of TRPV1, phosphorylated phosphoinositide 3-kinase (p-PI3K), and phosphorylated protein kinase B (p-Akt) in the aortic root. Real-time quantitative polymerase chain reaction (Real-time PCR) was used to detect endothelial nitric oxide synthase (eNOS) mRNA expression in the aorta, and Western blot was used to detect TRPV1 protein expression. ResultsCompared with the normal group, the model group showed a significant increase in aortic plaque formation (P<0.01) and significantly elevated levels of TNF-α and IL-1β in the aortic root (P<0.01). The expression levels of TRPV1, p-PI3K, and p-Akt were decreased (P<0.05, P<0.01), and eNOS mRNA expression was reduced (P<0.05, P<0.01). Compared with the model group, all Renshentang groups significantly reduced aortic plaque formation (P<0.01), significantly decreased TNF-α and IL-1β levels (P<0.01), and markedly increased the expression levels of TRPV1, p-PI3K, p-Akt, and eNOS mRNA (P<0.05, P<0.01). ConclusionRenshentang may inhibit endothelial inflammation and suppress the formation of AS by increasing TRPV1 protein expression and up-regulating the PI3K/Akt/eNOS signaling pathway, which may be one of the molecular mechanisms underlying its therapeutic effect against AS.

Schizophrenia is a chronic and debilitating mental disorder.Around 20%to 40%of patients do not respond well to normal antipsychotic medication,and are ultimately diagnosed with treatment-resistant schizophrenia(TRS),representing the most severe and challenging form of schizophrenia.Currently,clozapine is the standard treatment for TRS.Early identification and standardized treatment can be beneficial to patients with TRS by controlling acute-phase symptoms as soon as possible,reducing suicidal rate and improving their quality of life.Under the guidance of the Steering Committee,this consensus was formed after multiple discussions by 30 psychiatric experts and anonymous Delphi surveys including 17 consensus opinions on treatment-resistant schizophrenia,which cover risk factors and prevention,diagnosis and evaluation,standardized clozapine treatment and management of adverse reactions,treatment regimens for clozapine resistance and intolerance,and psychosocial intervention,etc.The consensus-making process also incorporated evidence-based medicine to help standardize and guide diagnosis and treatment for adults with TRS in China.

ObjectiveTo explore the effects of Renshentang on atherosclerosis (AS) in mice based on the role of transient receptor potential vanilloid1 (TRPV1) in regulating cholesterol metabolism in foam cells. MethodsNine SPF-grade 8-week-old C57BL/6J mice were set as a normal group, and 60 ApoE-/- mice were randomized into model, positive drug (simvastatin, 0.02 g·kg-1·d-1), and low-, medium-, and high-dose (1.77, 3.54, 7.08 g·kg-1·d-1, respectively) Renshentang groups (n=12) according to body weight. The normal group was fed with a normal diet, and the other groups were fed with a high-fat diet and given corresponding drugs by oral gavage for the modeling of AS. The mice were administrated with corresponding drugs once a day for 12 weeks. After the last administration and fasting for 12 h, the aorta was collected. Plaque conditions, pathological changes, levels of total cholesterol (TC), triglcerides (TG), low-density lipoprotein-cholesterol (LDL-C), and high-density lipoprotein-cholesterol (HDL-C), and the expression of TRPV1, liver X receptor (LXR), inducible degrader of the low-density lipoprotein receptor (IDOL), and low-density lipoprotein receptor (LDLR) in the aortic tissue were observed and detected by gross oil red O staining, HE staining, Western blot, immunohistochemistry, and real-time PCR. ResultsCompared with the normal group, the model group presented obvious plaque deposition in the aorta, raised levels of TC, TG, and LDL-C in the serum (P<0.01), up-regulated expression level of LDLR in the aorta (P<0.01), lowered level of HDL-C in the serum, and down-regulated expression levels of TRPV1, LXR, and IDOL in the aorta (P<0.05, P<0.01). Compared with the model group, the positive drug and Renshentang at different doses alleviated AS, elevated the levels of HDL-C, TRPV1, LXR, and IDOL (P<0.05, P<0.01), while lowering the levels of TC, TG, LDL-C, and LDLR (P<0.05, P<0.01). ConclusionRenshentang has a lipid-lowering effect on AS mice. It can effectively reduce lipid deposition, lipid levels, and plaque area of AS mice by activating TRPV1 expression and regulating the LXR/IDOL/LDLR pathway.
