Association Between Metabolic Risk Factors and Cognitive Impairment in Schizophrenia Based on Sex

Objective@#Sex differences have been observed in many aspects of schizophrenia, including cognitive deficits. Despite extensive research into the relationship between metabolic factors and cognitive deficits in schizophrenia, few studies have explored the potential sex difference in their association. @*Methods@#We recruited 358 schizophrenia patients and 231 healthy controls. The participants underwent measurements of body mass index (BMI), waist circumference, blood pressure, triglycerides, high-density lipoprotein cholesterol, and fasting blood glucose. Metabolic risk factors included abdominal obesity, hypertension, hyperglycemia, and dyslipidemia. A collection of these metabolic risk factors has been defined as metabolic syndrome. These diagnoses were based on the criteria of the National Cholesterol Education Program’s Adult Treatment Panel III. Cognitive performance was measured using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). A descriptive analysis, difference analysis, and linear regression model were used to identify the metabolic risk factors for cognitive function in schizophrenia. @*Results@#Our findings revealed sex differences in the rate of abdominal obesity and hypertension in schizophrenic patients. Additionally, we observed sex differences in the association between metabolic risk factors and cognitive impairment in schizophrenia. Specifically, hyperglycemia was associated with the immediate memory index score of RBANS in male patients, while dyslipidemia was associated with language, attention, delayed memory index scores, and RBANS total score in female patients. @*Conclusion@#Our results suggest that sex should be considered when evaluating the impact of metabolic disorders on the cognitive function of schizophrenic patients. Moreover, our study identifies hyperglycemia and dyslipidemia as potential targets for precise treatment by sex stratification, which could benefit the improvement of cognitive impairment in schizophrenic patients.

Bie Jia Jian pill enhances the amelioration of bone mesenchymal stem cells on hepatocellular carcinoma progression.

BACKGROUND: The therapeutic efficiency of Traditional Chinese Medicine (TCM) in suppressing the recurrence and metastasis of hepatocellular carcinoma (HCC) has been well proved. OBJECTIVE: The aim of this study is to investigate the role of Bie Jia Jian pill (BJJP) combined with bone mesenchymal stem cells (BMSCs) in HCC progression. METHODS: Flow cytometry was used to identify BMSCs isolated from BALB/c mice. The expressions of biomarkers and apoptosis rate of cancer stem cells (CSCs) enriched from Huh7 cells were also measured. The osteogenic differentiation and adipogenic differentiation ability of isolated BMSCs was determined by oil red O staining and Alizarin Red Staining. CSCs were used to establish the orthotopic HCC model. Histological changes in the liver tissues were examined by hematoxylin-eosin (H&E) staining and Van Gieson (VG) staining. The cell apoptotic rate in the cancer tissues was detected by TUNEL staining. The cell proliferation antigen Ki67 in the cancer tissues were detected by immunofluorescence assay and PCR, respectively. The levels of CSCs cellular surface markers (CD24, CD133 and EpCAM) and Wnt/ß-catenin signal pathway related proteins were detected by PCR and western blot. RESULTS: Treatment of BJJP or BMSCs both improved the morphology induced by HCC and suppressed the differentiation ability of CSCs, as evidenced by down-regulated expressions of CD24, CD133, EpCAM and Ki67. The protective effect of BJJP or BMSCs in cancer tissues can be enhanced by the combination of BJJP and BMSCs. In addition to that, BJJP or BMSCs alone was found to increase the expression of miR-140 and promote cell apoptosis in CSCs, while down-regulation of miR-140 partially reversed the protective effect of BMSCs or BJJP + BMSCs on cancer tissues. BJJP + BMSCs treatment together also can down-regulate the expressions of Wnt3a and ß-catenin. CONCLUSIONS: These results proved the inhibitory role of BJJP + BMSCs in HCC development through regulating miR-140 and Wnt/ß-catenin signal pathway.

Bie Jia Jian Pill Combined with Bone Mesenchymal Stem Cells Regulates microRNA-140 to Suppress Hepatocellular Carcinoma Stem Cells.

BACKGROUND AND OBJECTIVES: Cancer stem cells (CSCs) with tumorigenic potential are reported as the crucial factors of hepatocellular carcinoma (HCC) recurrence and therapy resistance. Bone mesenchymal stem cells (BMSCs) are documented to play an important role in the protection of hepatocytes. Bie Jia Jian pill (BJJP), a Traditional Chinese Medicine, has been used to treat liver fibrosis and liver cancer. This study aimed to explore the potential role of combined use of BJJP with BMSCs in HCC cell lines. METHODS AND RESULTS: Flow cytometry was used to identify BMSCs isolated from BALB/c mice and CSCs enriched from Huh7 cells by measuring CD24, CD133, CD44, CD73, CD105, CD166, CD29, CD14 and CD34. Differentiation potential of BMSCs was also determined. Cell viability and proliferation ability of CSCs were determined by CCK-8 assay and clone formation assay. The expressions of CSCs biomarkers and Wnt/ß-catenin signal pathway related proteins were determined by PCR and western blot. TOP-Flash/FOP-Flash luciferase assay was applied to measure the activity of ß-catenin/TCF. Compared with untreated CSCs, BJJP or BMSCs treatment alone on CSCs lead to increased miR-140 expression and cell apoptosis, as well as decreased expressions of CD24, CD133, EpCAM and cell viability. Downregualted expressions of Wnt/ß-catenin signal pathway related proteins, Wnt3a and ß-catenin were found in response to BJJP or BMSCs treatment alone. The combination of BJJP＋BMSCs treatment on CSCs could further enhance the suppressive effect on CSCs. Down-regulation of miR-140 in CSCs partially blocked the effects of BMSCs or BMSCs＋BJJP on the expressions of Wnt3a and ß-catenin as well as the cell viability and apoptosis of CSCs. Reversed expression pattern was found in CSCs transfected with miR-140 overexpression. CONCLUSIONS: Taken together, we demonstrate that BJJP＋BMSCs together could further enhance the suppressive effect on CSCs through regulating miR-140 and suppressing Wnt/ß-catenin signal pathway. This study demonstrated the potential of BJJP＋BMSCs in therapeutic treatment of HCC.

Literature Analysis of ADR Induced by Dasatinib / 中国药房

OBJECTIVE:To investigate ADR induced by dasatinib,and to provide reference for clinical rational drug use. METHODS:By means of literature metrology method,dasatinib-induced ADR cases domestically and internationally reported were analyzed. RSEULTS:A total of 63 ADR cases were induced by dasatinib,and the age of patients were mainly 41-60 years old. The most cases(25.4%)occurred within 1 month of medication. The patients mainly were from Asian countries and regions(53.9%). Organs/systems involved in dasatinib induced ADRs were mainly respiratory system(40.1%),digestive system(17.5%)and hema-tologic system(11.7%). Main clinical manifestations were pleural effusion(23 cases),pulmonary artery hypertension(15 cases), expiratory dyspnea(8 cases),diarrhea(8 cases),etc. CONCLUSIONS:Daring the use of dasatinib,great importance should be attached to ADR monitoring and prevention so as to avoid serious ADR.
