Objective To study the effect of coenzymes complex combined with vitamin E on liver and kidney inju-ry induced by neonatal hyperbilirubinemia. Methods One hundred and fifty full-term neonatals with hyperbilirubinemia were chosen as observation groups, who were divided into mild, moderate and severe groups according bilirubin. Forty five healthy full-term newborns in the same period, who are either healthy or with physiological jaundice, were selected as con-trol group. Serum total bilirubin, gamma-glutamyl transferase (γ-GGT) , Malondialdehyde (MDA) and Cys-C were measured within 24 hours of hospital admission.The observation groups were randomly divided into regular and combined treatment groups. Coenzymes complex combined with vitamin E were given in addition to regular method to combined group while reg-ular group only received regular methods.All above biochemical indexes were tested in the 7th day after medication admin-istration. Results Serum MDA were higher in all observation groups (mild, moderate and severe groups) than in control group (P＜0.05);but the levels ofγ-GGT and Cys-C increased in moderate and severe groups compared with control group (P＜0.05). There were positive correlations (P＜0.05) between levels of serum total bilirubin with MDA,γ-GGT and Cys-C. Positive linear correlation were found between MDA with γ-GGT and Cys-C(P＜0.01). After early intervention,γ-GGT, Cys-C and MDA declined with drop of bilirubin level. This is more prominent and faster in a in combined treatment group than regular group (P＜0.05).Conclusion In hyperbilirubinemia newborns, lipid peroxidation activated by bilirubin may lead to damages of liver and kidney. Coenzymes combined with vitamin E have protective effect to these damages.

Objective To explore the efficacy of acupuncture in the treatment of nonalcoholic fatty liver disease by using magnetic resonance iterative decomposition of water and fat with echo asymmetry and least-squares estimation-quantitative FAT/R2 * imaging (IDEAL-IQ) technique.Methods Totally 36 patients with nonalcoholic fatty liver were divided into acupuncture group (25 cases) and control group (11cases).The patients were performed liver magnetic resonance IDEAL-IQ and the liver fatty component value (F value) was measured before and after the treatment,at the same time clinical indicators of liver function and blood lipid were measured.The Spearman correlation analysis was used to compare the consistency of F value and blood lipid in all patients.The t test was used to compare the differences of liver F values,liver function,blood lipids and other clinical indicators of two groups before and after the treatment.Results There were significantly positive correlation between the fat component and triglyceride (TG),total cholesterol (TC) level (r =0.836,0.852,P ＜ 0.05),and significant negative correlation between the fat component and high density lipoprotein (HDL) level in the fatty liver group (r =-0.735,P ＜0.05),The liver F values,alanine aminotransferase (ALT) and aspartate aminotransferase (AST) contents and TG,HDL,low density lipoprotein (LDL) and TC contents of the acupuncture group after treatment were statistically significant (P ＜ 0.05).Comparison of each index in the acupuncture group after treatment with the control group,the differences were statistically significant (P ＜ 0.05).Conclusions Acupuncture is an effective approach to treat nonalcoholic fatty liver disease,as it can improve liver function and down-regulate lipid level.Magnetic resonance IDEAL-IQ technique can quantitatively detect its therapeutic efficacy.

Objective To investigate the expression of suppressor of cytokine signaling genes (SOCSs) and JAKs mRNA in the acute myloid leukemia(AML) patients. Methods The expression of SOCSs and JAKs mRNA as well as TYK2 in AML patients and healthy adults as normal contrals (NC) was measured with RT-PCR. Results The expression of SOCS 1,4,5 and 7 in AML patients was lower than those in normal control and AML with remis-sion (P<0.01),but the expression of SOCS 3 and 6 was higher than those in normal control and remission AML(P<0.01),however there was no significant difference in SOC2 between groups. The expressions of JAK2 ,JAK3 and TYK2 in AML were significantly higher than those in patients with remission and normal control(P<0.05). The ex-pression of JAK1 mRNA in relapsed AML was higher than that in normal control group(P<0.05),but the latter has no statistical significance between beginning treatment and normal group(P>0.05). Conclusion The deletion and degradion of SOCS 1,4,5 and 7 present in AML patients and JAKs expression is significantly increased, suggesting that both of them may co-participate in the pathogenesis of AML.

Objective To investigate the sleep quality and influencing factors in patients with stable myasthenia gravis (MG).Methods From September 2015 to February 2017,151 cases of stable MG were enrolled in the department of neurology,West China Hospital,Pittsburgh sleep quality index (PSQI) was used to evaluate their sleep quality;Spearman analysis was used to analyze the influencing factors (clinical data,quality of life,anxiety and depression).Results Spearman test analysis showed that PSQI was positively correlated with age,duration,myasthenia gravis quality of life 15 (MG-QOL15),Hamilton Anxiety Scale 14 (HAMA14),Hamilton Depression Scale 24 (HADA24) (P ＜ 0.05).Stepwise regressionanalysis further revealed that life quality was the best predictor of reduced sleep quality (t =3.161,P =0.002),followed by anxiety (t =2.495,P =0.014) and age (t =2.356,P =0.020).Conclusions There are many influencing factors of stable MG wnich more attentions should be paid on.

BACKGROUND/OBJECTIVES: A variety of immunomodulators can improve the efficacy of low-dose chemotherapeutics. Active hexose correlated compound (AHCC), a mushroom mycelia extract, has been shown to be a strong immunomodulator. Whether AHCC could enhance the antitumor effect of low-dose 5-fluorouracil (5-FU) via regulation of host immunity is unknown. MATERIALS/METHODS: In the current study Hepatoma 22 (H22) tumor-bearing mice were treated with PBS, 5-FU (10 mg.kg-1.d-1, i.p), or AHCC (360 mg.kg-1.d-1, i.g) plus 5-FU, respectively, for 5 d. CD3+, CD4+, CD8+, and NK in peripheral blood were detected by flow cytometry. ALT, AST, BUN, and Cr levels were measured by biochemical assay. IL-2 and TNFalpha in serum were measured using the RIA kit and apoptosis of tumor was detected by TUNEL staining. Bax, Bcl-2, and TS protein levels were measured by immunohistochemical staining and mRNA level was evaluated by RT-PCR. RESULTS: Diet consumption and body weight showed that AHCC had no apparent toxicity. AHCC could reverse liver injury and myelosuppression induced by 5-FU (P < 0.05). Compared to mice treated with 5-FU, mice treated with AHCC plus 5-FU had higher thymus index, percentages of CD3+, CD4+, and NK cells (P < 0.01), and ratio of CD4+/CD8+ (P < 0.01) in peripheral blood. Radioimmunoassay showed that mice treated with AHCC plus 5-FU had the highest serum levels of IL-2 and TNFalpha compared with the vehicle group and 5-FU group. More importantly, the combination of AHCC and 5-FU produced a more potent antitumor effect (P < 0.05) and caused more severe apoptosis in tumor tissue (P < 0.05) compared with the 5-FU group. In addition, the combination of AHCC and 5-FU further up-regulated the expression of Bcl-2 associated X protein (Bax) (P < 0.01), while it down-regulated the expression of B cell lymphoma 2 (Bcl-2) (P < 0.01). CONCLUSIONS: These results support the claim that AHCC might be beneficial for cancer patients receiving chemotherapy.

It is a significant challenge to improve the blood-brain barrier (BBB) permeability of central nervous system (CNS) drugs in their development. Compared with traditional pharmacokinetic property tests, machine learning techniques have been proven to effectively and cost-effectively predict the BBB permeability of CNS drugs. In this study, we introduce a high-performance BBB permeability prediction model named balanced-stacking-learning based BBB permeability predictor(BSL-B3PP). Firstly, we screen out the feature set that has a strong influence on BBB permeability from the perspective of medicinal chemistry background and machine learning respectively, and summarize the BBB positive(BBB+) quantification intervals. Then, a combination of resampling algorithms and stacking learning(SL) algorithm is used for predicting the BBB permeability of CNS drugs. The BSL-B3PP model is constructed based on a large-scale BBB database (B3DB). Experimental validation shows an area under curve (AUC) of 97.8% and a Matthews correlation coefficient (MCC) of 85.5%. This model demonstrates promising BBB permeability prediction capability, particularly for drugs that cannot penetrate the BBB, which helps reduce CNS drug development costs and accelerate the CNS drug development process.
