RESUMEN

Background/Aims@#Chronic hepatitis B (CHB) and fatty liver (FL) often co-exist, but natural history data of this dual condition (CHB-FL) are sparse. Via a systematic review, conventional meta-analysis (MA) and individual patient-level data MA (IPDMA), we compared liver-related outcomes and mortality between CHB-FL and CHB-no FL patients. @*Methods@#We searched 4 databases from inception to December 2021 and pooled study-level estimates using a random- effects model for conventional MA. For IPDMA, we evaluated outcomes after balancing the two study groups with inverse probability treatment weighting (IPTW) on age, sex, cirrhosis, diabetes, ALT, HBeAg, HBV DNA, and antiviral treatment. @*Results@#We screened 2,157 articles and included 19 eligible studies (17,955 patients: 11,908 CHB-no FL; 6,047 CHB-FL) in conventional MA, which found severe heterogeneity (I2=88–95%) and no significant differences in HCC, cirrhosis, mortality, or HBsAg seroclearance incidence (P=0.27–0.93). IPDMA included 13,262 patients: 8,625 CHB-no FL and 4,637 CHB-FL patients who differed in several characteristics. The IPTW cohort included 6,955 CHB-no FL and 3,346 CHB-FL well-matched patients. CHB-FL patients (vs. CHB-no FL) had significantly lower HCC, cirrhosis, mortality and higher HBsAg seroclearance incidence (all p≤0.002), with consistent results in subgroups. CHB-FL diagnosed by liver biopsy had a higher 10-year cumulative HCC incidence than CHB-FL diagnosed with non-invasive methods (63.6% vs. 4.3%, p<0.0001). @*Conclusions@#IPDMA data with well-matched CHB patient groups showed that FL (vs. no FL) was associated with significantly lower HCC, cirrhosis, and mortality risk and higher HBsAg seroclearance probability.

RESUMEN

Vertebral artery type cervical spondylosis is a common type of cervical spondylosis, also known as cervical vertigo. In recent years, with the increase of people's life pace and the number of office staff, the incidence rate has been rising year by year, with a trend of younger age. Because traditional Chinese medicine has unique advantages in treating cervical vertigo, it is necessary to study the regularity of the Chinese medicine for cervical vertigo. But at present, the research is mainly based on the statistics for frequency and proportion of herbs. In addition, in the process of diagnosis and treatment of Chinese medicine, personal experience also caused differences in prescription compatibility and drug dosage, which makes difficult guarantee for the safety and effectiveness of drug treatment. So, this paper is based on literatures about the traditional Chinese medicine in treatment of cervical vertigo in the past 5 years, by using association rules algorithm, complex system entropy clustering and other non supervised data mining methods. Analysis was made for the use of various drugs in the frequency, the association rules, the core drug combination and the new prescriptions. The traditional Chinese medicine inheritance support system(TCMISS) was utilized to analyze 154 drugs from the 101 prescriptions, determine the use frequency of drugs, analyze the characteristics and the compatibility of core drugs, and dig out 14 core drug combinations and 7 new prescription combinations. The prescription and medication regularities illustrates the drugs for treatment of cervical vertigo, including those for flating liver and suppressing yang, invigorating the circulation of blood to remove blood stasis, reducing water and permeating dampness, increasing qi and activating blood, and nourishing the liver and kidney mainly. Treatment rules are nourishing liver and kidney, invigorating the circulation of blood stasis Tongqiao, reducing phlegm and dampness, flating liver and suppressing yan, dredging collaterals, supplementing qi and nourishing blood. This study aims to summarize frequently used single herbs for vertebral artery type cervical spondylosis, combinations of frequently used herbs and dosage of frequently used herbs with significant efficacy, define the current prescription and medication regularities for treating cervical vertigo and give guidances for clinical mediation.

RESUMEN

OBJECTIVE: To determine the neuro-protective effects of albiflorin against MPP+-induced PC12 cells death and related molecular mechanisms. METHODS: PC12 cells were treated with 4 mmol·L-1 MPP+ to establish apoptotic cell models. MTT method, DCFH-DA staining, JC-1 staining and Western Blot were used to determine the changes of cell viability, intracellular ROS concentration, mitochondrial membrane potential and the expression of Bel-2 and Bcl-X1, and the phosphoration of Akt/GSK3β in PC12 cells. RESULTS: Albiflorin showed significantly neuro-protective effects against MPP+-induced cell damage. Results showed that albiflorin enhanced the cell viability, reduced intracellular ROS level and caspase 3 activation, restored the mitochondrial membrane potential, increased the expression of Bcl-2 and Bcl-X1, and enhanced the phosphoration of Akt/GSK3β. CONCLUSION: Albiflorin shows neuro-protective effects against MPP+-induced PC12 cells damage via mitochondrial-dependent pathway and Akt/GSK3β signaling.

RESUMEN

OBJECTIVE: To investigate the anti-hepatocellular carcinoma effect and underlying mechanisms. METHODS: In PLC/PRF/5 and HepG2, after treatment with Grifola frondosa extract, MTT method, chemical method, JC-1 staining and Western Blot were applied to determine cell viability, caspase 3 activity, mitochondrial membrane potential, the expression of Bcl-2 and Bax, and the phosphorylation of Akt/GSK3β. The anti-tumor activity of Grifola frondosa extract was further confirmed in PLC/PRL/5-xengrafted mice model. RESULTS: Grifola frondosa extract significantly reduced cell viability, mitochondrial membrane potential, the expression of Bcl-2 and the phosphorylation of Akt/GSK3β, and enhanced LDH release, caspase 3 activity and the expression of Bax in both PLC/PRF/5 and HepG2 cells. 12-day Grifola frondosa extract treatment significantly inhibited the PLC/PRF/5-xenografted tumor growth without influence the body weight of mouse. CONCLUSION: All these data indicate that Grifola frondosa extract-mediated anti-hepatocellular carcinoma effects are related to its modulation of the activations of Akt/GSK3β and mitochondrial pathway.
