Cognitive impairments are the hallmark of schizophrenia and prominent in the early episode stage. However, the underlying pathological mechanisms of cognitive impairments are not fully understood. This study aimed to investigate the abnormal functional connectivity (FC) of the cerebellar dentate nucleus (DN) and its correlation with cognitive impairments in patients with drug-naive and first-episode schizophrenia.

Working memory research has primarily concentrated on studying our senses separately; the neural basis of maintaining information from multiple sensory modalities in working memory has been not well elucidated. It is debated whether multisensory information is maintained in the form of modality-specific representations or amodal representations. The present study investigated what brain regions were engaged in both types of complex audiovisual objects maintenances (semantically congruent and incongruent) using functional magnetic resonance imaging and conjunction analysis, and examined in which form to maintain multisensory objects information in working memory.

Interest in the promotion of well-being has blossomed in recent years, and it is widely reported that positive psychological interventions (PPIs) can effectively improve SWB. However, to date, the neural correlates of PPIs remain elusive.

Methods: We retrospectively analyzed the efficacy of switching to tenofovir disoproxil fumarate in suboptimal responders to lamivudine plus adefovir. Charts were reviewed for LAM-resistant chronic hepatitis B (CHB) patients who visited the Zhejiang Province People's Hospital and The First Affiliated Hospital, College of Medicine, Zhejiang University, from June 2009 to May 2013.
Aim: To study the effect of salvianolate on tight junctions (TJs) and zonula occludens protein 1 (ZO-1) in small intestinal mucosa of cirrhotic rats.
Methods: Cirrhosis was induced using carbon tetrachloride. Rats were randomly divided into the untreated group, low-dose salvianolate (12 mg/kg) treatment group, medium-dose salvianolate (24 mg/kg) treatment group, and high-dose salvianolate (48 mg/kg) treatment group, and were treated for 2 wk.
Objective: To analyse the emergence of YMDD motif (tyrosine-methionine-aspartate-aspartate) variants in patients with hepatitis B treated with lamivudine.
Methods: The amino acid substitution from methionine or isoleucine at the YMDD motif at the HBV polymerase gene is a main mutation resistant to lamivudine treatment. Generated from a fragment of domain C of the polymerase gene, patients' HBV DNA, which had been positive previously became positive again ever since it had been negative during lamivudine therapy.
Objective: To study the types and emergence time of YMDD motif mutation in hepatitis B virus (HBV) polymerase gene during lamivudine treatment.
Methods: The serum samples were collected from 33 patients with HBV DNA rebounding and 2 non-responders after at least one year lamivudine treatment. HBV polymerase gene was amplificated by PCR, then the products were detected by restriction fragment length polymorphism (RFLP) and by direct sequence analysis.
