RESUMO
Crigler-Najjar syndrome (CNS) is an autosomal recessive disorder in which the content of plasma unconjugated bilirubin is increased due to the reduction or complete deficiency of the activity of bilirubin uridine diphosphate glucuronosyl transferase 1A1 (UGT1A1), classified as CNS type Ⅰ and Ⅱ. CNS type Ⅰ is the most severe, which will develop into kernicterus, damage the brain nervous system, and even threaten the life of patients. This article introduces six CNS treatment techniques, including phototherapy, plasma exchange, drug therapy, liver transplantation, hepatocyte transplantation and gene therapy. The applicable patient types, treatment effects and existing deficiencies of each technique were summarized. Phototherapy, plasma exchange, drug therapy and hepatocyte transplantation can temporarily control serum levels and reduce the risk of jaundice, but cannot completely restore UGT1A1 enzyme activity; liver transplantation is currently the only treatment option for CNS type Ⅰ patients, but is limited by suitable liver donors and post-operative immune rejection. Gene therapy has the most promising application in the treatment of genetic disorders such as CNS, which can provide more viable therapeutic techniques for CNS patients.

RESUMO
Long non-coding RNAs (lncRNAs) play important roles in several cellular biogenic activities, including the virus-host interaction as well. Virus infection could induce aberrant expression of multiple lncRNAs, and some of these lncRNAs could facilitate or suppress the virus infection via diverse mechanisms. In this paper, we enumerate the differentially expressed lncRNAs induced by different types of viruses and summarize the potential mechanism of interaction between viruses and these lncRNAs.

Objective@#To investigate the relationship between M2-polarized macrophages and early response in multiple myeloma and its molecular mechanism.@*Methods@#Two hundred and forty bone marrow biopsy tissue were collected and M2-polarized macrophages were stained by anti-CD163 monoclonal antibody. In vitro M2-polarized macrophages were derived from human peripheral blood mononuclear cell or THP-1 cells and identified by flow cytometry. Two myeloma cell lines RPMI 8226 and U266 were co-cultured with M2 macrophages using a transwell system. We measured myeloma cells proliferation through CCK-8 method and the pro-inflammatory cytokines expression (TNF-α and IL-6) by ELISA. Real time PCR was applied to measure chemokines (CCL2 and CCL3) , chemokine receptors (CCR2, CCR5) , VEGF and their receptors. In addition, flow cytometry was used to analyze the apoptosis of myeloma cells induced by dexamethasone.@*Results@#①Patients with high percentage of M2 macrophage involvement in bone marrow showed poorer response (23.9% versus 73.0%, χ2=60.31, P<0.001). ② In vitro the proliferation of RPMI 8226 cells (P=0.005 at 24 h, P=0.020 at 36 h) or U266 myeloma cells (P= 0.030 at 24h, P=0.020 at 36h) co-cultured with M2-polarized macrophages was higher than control group. ③In vitro the apoptotic rate of RPMI 8226 cells (29.0% versus 71.0%, t=4.97, P=0.008) or U266 myeloma cells (24.9% versus 67.7%, t=6.99, P=0.002) co-cultured with M2-polarized macrophages was lower than control group. ④ In vitro M2-polarized macrophages promoted myeloma cells secreting higher level of IL-6, TNF-α and higher expression of CCL2, CCL3, CCR2, CCR5, VEGFA, VEGFR-1,-2 compared with the non-macrophage co-culture system.@*Conclusion@#M2-polarized macrophages promote myeloma cells proliferation and inhibit apoptosis through a very complex mechanism involving pro-inflammatory cytokines IL-6 and TNF-α, chemokines and related receptors such as CCL2, CCL3, CCR2, CCR3, and VEGF as well as related VEGFR.
RESUMO
Phenylketonuria (PKU) is a newborn inherited metabolic disorder caused by the genetic deficiency of hepatic enzyme phenylalanine hydroxylase (PAH) which thus in metabolic disorder of phenylalanine. In this study, ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was used to analyze the accurate amount of coenzyme Q10 (CoQ10) and the relative amount of CoQ9 in newborn dried blood spot (DBS) collected from 5 PKU newborns (3 and 30 days after birth, respectively) and 20 healthy newborns. The content of CoQ10 was (122.1±24.9 ng/mL) and (59.0±12.0 ng/mL) in DBS from healthy newborns and PKU newborns, respectively. The relative contents of cholesterol and glucose in the DBS were determined by gas chromatography-mass spectrometry (GC-MS). In comparison with healthy newborn group, the levels of CoQ10, CoQ9, cholesterol and glucose were all significantly decreased in PKU newborns. The increased content of Phe and the decreased content of CoQ10 showed significant inverse correlation in the DBS from PKU. This study provides references for diet therapy of PKU newborns.
RESUMO
Objective To study the 18F-FDG PET/CT features of tuberculous and malignant diffuse peritoneal lesions and to discuss the diagnostic value of 18F-FDG PET/CT in diagnosing and differentiating the lesions. Methods The 18F-FDG PET/CT features of 72 patients with tuberculous peritonitis,28 primary serous papillary carcinoma of the peritoneum and 135 peritoneal metastases confirmed by clinic and/or histopathology, were retrospectively reviewed. The peritoneal thickening features of tuberculous and malignant peritoneal lesions were observed. The maximal standardized uptake value (SUVmax) of peritoneal lesions and ascites, ascites SUVmax/liver SUVmax (T/NT) were compared between tuberculous peritonitis and cancerous peritonitis. The ROC curve was used to analyze the diagnostic efficiency of T/NT, SUVmax of peritoneal lesions and ascites. Results The typical 18F-FDG PET/CT features of tuberculous peritonitis were uniformity thickening of parietal peritoneum, mesenteric and omental stain like changes, widely and even distribution of the peritoneal 18F-FDG, while the cancerous peritonitis was obvious uneven thickening of parietal peritoneum, mesenteric and omental nodules and pie-shape changes, uneven distribution of the peritoneal 18F-FDG. The degree of 18F-FDG uptake was increased in all peritoneal lesions, and there was no significant difference between the tuberculous group (SUVmax=10.53±5.44) and the cancerous group (SUVmax=11.45±6.78, t=1.017, P>0.05). The 18F-FDG concentration in malignant ascites (SUVmax=1.88±0.65,T/NT=0.73± 0.18) was obvious higher than that of tuberculous ascites (SUVmax=1.67±0.69,T/NT=0.57±0.27, t=2.243 and 5.045,both P<0.05). The area under the ROC curve of T/NT, SUVmax of ascites, SUVmax of peritoneal lesions were 0.707, 0.593, 0.536, respectively. Conclusion The 18F-FDG PET/CT imaging can reflect the morphology and metabolic changes of peritoneal lesions. It is important to combine the SUVmax of ascites in order to improve the efficiency of diagnosing the diffuse peritoneal diseases.

RESUMO
Bone marrow stromal antigen 2 (BST-2) is a kind of host restriction factor. Since it was discovered to be responsible for the defect in virion release of HIV-1 mutants lacking the accessory gene vpu in 2008, it was thought to mainly restrict the viruses by directly tethering viral particles at the plasma membrane. Recent reports suggest that BST-2 also can inhibit the the release of HBV particles, which are budding in the intracellular vesicles, expanding the antiviral spectrum of BST-2. Futhermore, the machanism that BST-2 used to restrict HBV release in multivesicular bodies (MVBs) is similar to that used to restrict HIV at the plasma membrane. However, HBV have evolved strategies to antagonize the antiviral action of BST-2. There are two different opinions about the antagonist. One is HBV inactivated BST-2 by HBx requiring a hepatocyte-specific environment. Another thought envelope protein HBs counteract the antiviral action of BST-2. In this review, we focus on the current advances in the anti-HBV activity of BST-2.
