RESUMEN
Chronic hepatitis B (CHB) is a global epidemic disease caused by hepatitis B virus that can lead to hepatic failure, even liver cirrhosis and hepatocellular carcinoma. The occurrence and development of CHB are closely related to the changes in the gut microbiota communities. To explore the relationship between the structure of gut microbiota and liver biochemical indicators, 14 CHB patients (the CHB group) and 11 healthy people (the CN group) were randomly enrolled in this study. Our results demonstrate that CHB caused changes in the gut microbiota communities and biochemical indicators, such as alanine transaminase, total bilirubin and gamma glutamyl transferase. Furthermore, CHB induced imbalance of the gut microbiota. Prevotella, Blautia, Ruminococcus, Eubacterium eligens group, Bacteroides uniformis and Ruminococcus sp. 5_1_39BFAA were associated with the critical biochemical indicators and liver injury, suggesting a new approach to CHB treatment.

Objective@#To determine the changes in peripheral plasma concentrations of interleukin-10 (IL-10), interleukin -12 (IL-12) and interfoeron-γ(IFN-γ) in the patients with chronic hepatitis B virus (HBV) infection and their correlations with HBV infection stage or HBV DNA load of HBV carriers.@*Methods@#Data of 135 patients with chronic HBV infection from March 2016 to March 2017 were collected, the patients included 32 chronic HBV carriers, 61 with chronic hepatitis and 42 with cirrhosis. Forty healthy subjects served as controls. The concentrations of IL-10, IL-12 and IFN-γ were determined using enzyme-linked immunosorbent assay (ELISA). Correlation analysis was performed using the Pearson correlation test, which was performed to analyze the correlation between IL-10, IL-12, IFN-γ and HBV infection stage, HBV DNA load of HBV carriers.@*Results@#Compared with those in healthy controls, plasma IL-10 and IL-12 levels in patients with chronic hepatitis and cirrhosis increased significantly (F=22.06, 15.67, P=0.013, 0.021), plasma IL-10 and IL-12 levels in cirrhosis cases were higher than those in chronic hepatitis (all P<0.001), plasma IL-10 and IL-12 levels in chronic hepatitis were higher than those in chronic HBV carriers (all P<0.001). Plasma IFN-γ level in chronic HBV carriers, chronic hepatitis and cirrhosis were significantly higher than those in healthy controls (F=18.36, P=0.017). There were statistically significant differences in IFN-γ levels among the three groups in the chronic HBV carriers, chronic hepatitis and cirrhosis. IL-10, IL-12 and IFN-γ levels of the low, medium and high HBV DNA load groups were statistically significant (all P<0.05). There was no correlation between IL-10 and HBV DNA. IFN-γ, IL-12 and HBV DNA load were negatively correlated. There was no correlation between IL-10 and IFN-γ (r=0.103, P>0.05), IL-12 and IFN-γ were significantly positively correlated (r=0.687, P<0.05).@*Conclusions@#IL-10, IL-12 and IFN-γ may play an important role in the chronic HBV infection.
RESUMEN
@#Objective To study the effect of electroencephalograph (EEG) bionic electrical stimulation at Wangu (GB12), Tianzhu (BL10), Neiguan (PC6) on cerebral blood flow and metabolism in patients with persistent vegetative state (PVS). Methods 60 patients with PVS were divided into observation group (n=30) and control group (n=30) according to the random number table. The control group received routine treatment, including basic management, hyperbaric oxygen therapy, awaking medicine, sensory stimulation, and so on; while the observation group received EEG bionic electrical stimulation at bilateral Tianzhu, Wangu (cheif electrodes) and Neiguan (auxiliary electrodes) in addition. They were treated for 30 days. They were assessed with the PVS score, and observed with transcranial Doppler ultrasound (TCD) and magnetic resonance spectroscopy (MRS) one day before and one day after treatment. Results The incidence of improvement was 86.67% in the observation group, more than 60.00% in the control group (P<0.05). The difference of blood flow velocity before and after treatment (ΔVm) of anterior-middle cerebral artery was more in the observation group than in the control group respectively (P< 0.001), as well as those of posterior cerebral-vertebral-basilar artery (P<0.01). The N-acetyl aspartic acid/creatine (NAA/Cr) increased more in the observation group than in the control group respectively (P<0.01), and the choline/creatine (Cho/Cr) decreased more (P<0.01), after treatment. Conclusion EEG bionic electrical stimulation can improve the cerebral circulation and metabolism in patients with PVS, which may associate with the wake promoting.

RESUMEN
Objective To study the functional connectivity (FC) pattern of anterior cingulated cortex in patients with vascular cognitive impairment with no dementia (VCIND) after subcortical ischemic vascular disease,and to analyze the relationship between FC and cognitive function.Methods Resting state functional magnetic resonance imaging (MRI) data were acquired from 14 patients with VCIND and 16 healthy volunteers with normal cognition.The altered functional connectivity pattern in VCIND was valuated by comparing to normal control.Then a correlation analysis was performed between the strength of FC and the Montreal Cognitive Assessment (MoCA) scores in patients with VCICD.Results (1) The visual space or executive function (3.14 ± 0.29),attention or computing power (3.79 ± 0.37),language (1.14 ± 0.21),directional power (4.14 ± 0.53) items,and the total points of MoCA (17.29 ± 1.53) in VCIND were significantly lower than that in the normal control group (4.93 ± 0.07,5.93 ± 0.07,2.93 ± 0.26,5.93 ± 0.07,27.57 ± 0.33 ; t =31.62,32.50,28.51,12.00,39.71,all P ＜ 0.05).While the abstract ability or memory (4.36 ± 0.74),the naming (2.79 ± 0.11) items in VCIND were not significantly different with that in the control group (4.79 ± 0.80,2.93 ± 0.07 ; t =1.76,1.00,both P ＞ 0.05).(2) Compared with the control group,the patients showed FC decrease between the anterior cingulated cortex and several brain regions,including the left middle temporal gyrus/left superior temporal gyrus,the left superior frontal gyrus/left middle frontal gyrus/left inferior frontal gyrus,the left posterior cingulated cortex/left precuneus,the left inferior parietal lobule/left angular gyrus,the right middle temporal gyrus/right superior temporal gyrus,the right orbit frontal cortex/right inferior frontal gyrus,the right inferior parietal lobule/right angular gyrums,and the right superior frontal gyrus/right middle frontal gyrus.There were also some regions that showed increased FC,which included the right posterior lobe of the cerebellum,the calcarine fissure,the left middle frontal gyrus,and the left precentral gyrus.(3) In the VCIND patients,the brain regions which positively correlated with the MoCA scores were the left inferior parietal lobule,the right middle temporal gyrus,the right superior frontal gyrus,and the left superior temporal gyrus.The negativerelated brain regions were the right posterior limb of internal capsule,the left middle temporal gyrus,the left precuneus,and the right anterior limb of internal capsule.Conclusions VCIND patients show abnormal FC pattern of anterior cingulated cortex,which could be the pathological basis of VCIND,and have certain predictive value for VCIND.
