Rhubarb anthraquinone derivatives (AQs) have been documented to have both therapeutic and toxic effect on liver and kidney, leading to a complex puzzle to assess their benefits and risks. In this study, the tissue distributions of AQs in SD rats after orally administrated extracts of raw and prepared rhubarb were examined whether they undergo different uptake. The total rhubarb extract (14.49 g x kg(-1) of body weight per day od, counted on the quantity of crude material) was administrated orally for 12 weeks. The concentrations of the AQs in different tissues were quantified by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The five major AQs, aloe-emodin, rhein, emodin, chrysophynol and physcion, could all be detected in the liver, kidney and spleen, while only rhein, aloe-emodin and emodin reached the quantitative limit. The tissue concentrations of AQs in raw rhubarb group were higher than that in steamed rhubarb group with rhein > emodin > aloe-emodin in the same tissue. On the whole, the tissue distribution of rhein was higher than that of emodin and aloe-emodin in liver, spleen and kidney. AQs could not be detected in those tissues after drug withdraw for 4 weeks, which suggested scarcely any accumulative toxicity of rhubarb. The result indicated that raw rhubarb had more tissue toxicity than steamed rhubarb and rhein may be one of the major poisonous ingredients. The results were concordant with the traditional Chinese medicine theory of toxicity-attenuating effect of processing.

Objective: To investigate the correlation between fat mass percentage(FM%), fat mass index(FMI), fat free mass index(FFMI), body mass index (BMI) and physical fitness, and to explore the potential value of body composition index in predicting physical exercise level of children and adolescents. Methods: Data came from 2013 revision of National Students Physical Health Standard of Ministry of Education in Beijing. Body composition of 4 069 children and adolescents aged 6-20 years in Beijing was measured by the BIA(inbody 230). FM, FMI, FFMI and BMI were divided into four groups by quartile method. The differences and trends of the four groups were analyzed by graphpad prism 8.0 software. Results: FM% (20.03±10.39) and FMIS [(4.35± 2.84 )kg/m 2] of oys were significantly lower than those of girls, while FFMI [(14.21±4.95)kg/m 2] and BMI [(20.31±4.27) kg/m 2 ] of boys were significantly higher than those of girls( t =-13.36, -7.66, 11.49, 8.16, P <0.01). In boys, with the increase of FM% and FMI, the performance of 50 m, 1 000 m, standing long jump and pull up showed a downward trend; with the increase of FFMI, the performance of 50 m, standing long jump and pull up had an obvious upward trend. In girls, with the increase of FM% and FMI, the 50 m running time was gradually shortened, and the 800 m running time was gradually increasing; High FFMI was associated with higher performance in 50 m running, while no association was observed between FFMI and 800 m running.Four body composition indicators showed no effects on performance of sitting forward flexion and 1 minute sit up. Conclusion FM%, FMI, FFMI and BMI have a good predictive effect on physical fitness of children and adolescents. Adolescents with higher FFMI, lower FM% and FMI have better muscle burst strength, muscle endurance, flexibility, aerobic ability and anaerobic ability, especially in boys.

OBJECTIVETo explore the therapeutic effect and the hemorrheology change of berberine in new diagnosed patients with type 2 diabetes combining nonalcoholic fatty liver disease.

METHODSixty patients, in our department from March 2009 to March 2010, with type 2 diabetes and nonalcoholic fatty liver disease were randomly divided into two groups. One group was given berberine, another group was given Xuezhikang, both for 12 weeks. The indicators, include B-ultrasound of liver, triglycerides (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), alanine aminotransferase (ALT), aspertate aminotransferase (AST), hemorrheology, were detected before and after treatment.

RESULTAfter treatment by berberine, B-ultrasound of liver were better than before, the effective rate was 70%, vs 73.3% after treatment by Xuezhikang. ALT, AST, TC, TG, LDL-L, hemorrheology (including the whole blood viscosity, whole blood viscosity, high cutting reduction of whole blood viscosity, plasma cutting reductive low viscosity, blood sedimentation, RBC deposited, fibrinogen) were significantly lower than before, however, HDL-L significantly increased (P<0.05). The therapeutic effect of xuezhikang was the same as berberine. The distance between the indicators of the two groups was no different.

CONCLUSIONBerberine can obviously improve the conditions of new diagnostic T2DM patients with nonalcoholic liver lesions, effectively reduce hemorrheology indicators, and has good application prospect.

Purpose: C5α receptor 1 (C5ΑR1) is associated with the development of various human cancers. However, whether it is involved in the development of hepatitis B virus (HBV)–related hepatocellular carcinoma (HCC) is poorly understood. We explored the expression, biological role, and associated mechanisms of C5AR1 in HBV-related hepatoma cells. Materials and Methods: The expression of C5ΑR1 mediated by HBV and HBV core protein (HBc) was detected in hepatoma cells. The function of nuclear factor кB (NF-κB) pathway in HBc-induced C5AR1 expression was assessed. The roles of C5ΑR1 in the activation of intracellular signal pathways, the upregulation of inflammatory cytokines, and the growth and migration of hepatoma cells mediated by HBc, were investigated. The effect of C5α in the development of HCC mediated by C5AR1 was also measured. Results: C5ΑR1 expression was increased in HBV-positive hepatoma cells. Dependent on HBc, HBV enhanced the expression of C5ΑR1 at the mRNA and protein levels. Besides, HBc could promote C5ΑR1 expression via the NF-κB pathway. Based on the C5ΑR1, HBc facilitated the activation of JNK and ERK pathways and the expression and secretion of interleukin-6 in hepatoma cells. Furthermore, C5ΑR1 was responsible for enhancing the growth and migration of hepatoma cells mediated by HBc. Except these, C5α could promote the malignant development of HBc-positive HCC via C5AR1. Conclusion We provide new insight into the mechanisms of hepatocarcinogenesis mediated by HBc. C5ΑR1 has a significant role in the functional abnormality of hepatoma cells mediated by HBc, and might be utilized as a potential therapeutic target for HBV-related HCC.

The continuing challenges that limit effectiveness of tumor therapeutic vaccines were high heterogeneity of tumor immunogenicity, low bioactivity of antigens, as well as insufficient lymph nodes (LNs) drainage of antigens and adjuvants. Transportation of in situ neoantigens and adjuvants to LNs may be an effective approach to solve the abovementioned problems. Therefore, an FA-TSL/AuNCs/SV nanoplatform was constructed by integrating simvastatin (SV) adjuvant loaded Au nanocages (AuNCs) as cores (AuNCs/SV) and folic acid modified thermal-sensitive liposomes (FA-TSL) as shells to enhance de novo antitumor immunity. After accumulation in tumor guided by FA, AuNCs mediated photothermal therapy (PTT) induced the release of tumor-derived protein antigens (TDPAs) and the shedding of FA-TSL. Exposed AuNCs/SV soon captured TDPAs to form in situ recombinant vaccine (AuNCs/SV/TDPAs). Subsequently, AuNCs/SV/TDPAs could efficiently transport to draining LNs owing to the hyperthermia induced vasodilation effect and small particle size, achieving co-delivery of antigens and adjuvant for initiation of specific T cell response. In melanoma bearing mice, FA-TSL/AuNCs/SV and laser irradiation effectively ablated primary tumor, against metastatic tumors and induced immunological memory. This approach served a hyperthermia enhanced platform drainage to enable robust personalized cancer vaccination.
