05). After treatment, the concentrations in the two groups were significantly lower than those before treatment (P < 0.05), and the concentrations in the observation group were significantly lower than those in the control group (P < 0.05). There was no significant difference in the 3-year OS between the observation and control groups (P > 0.05).

Nimotuzumab combined with cisplatin could improve the conditions of patients with nasopharyngeal carcinoma. After treatment, the expression of VEGF and MMP-2 decreased significantly. We speculated that it improves the survival rate of patients by reducing the expression of VEGF and MMP-2.

Heterocyclic materials are heavily studied in this regard due to the large variations in possible substrates. Herein we evaluated four different 5,6-fused ring heterocycles to gain a better understanding of any favorable optical and electronic properties that were due to incorporation of certain moieties. The molecules chosen would highlight the effects that the central ring (pyridazine versus oxazine), aromatic substituent, and heterocyclic side group may have on electronic and optical properties. Computational analysis of these four molecules was done using density functional theory (B3LYP and PBEPBE) with 6-31G(d,p), 6-311 ++G(d,p), and cc-pVTZ basis sets. The constituent molecules were optimized, and calculations were done for the dipole moment, polarizability, first-order hyperpolarizability (β), HOMO and LUMO orbitals, and a natural bonding order (NBO) analysis. Vismodegib These calculations allow for the study of charge density via electrostatic potential mapping and bonding orbitals. The results indicated that the pyridazine molecules presented here are more favorable than the oxazines for non-linear optical (NLO) applications. It is also noted that side ring substituents (thienyl and furyl) in the two pyridazines studied showed very little calculated differences. Finally, heterocyclic rings showed more favorable properties when incorporated as substituents for NLO applications over hydrocarbon aromatics. Graphical abstract.

Adult polyglucosan body disease (APBD) is an autosomal recessive leukodystrophy characterized by neurogenic bladder starting after 40 years old, spastic paraparesis and peripheral neuropathy. It is mainly resultant from the GBE1 homozygous p.Tyr329Ser (c.986A>C) mutation, especially in Ashkenazi-Jewish patients, although some cases of compound heterozygous have been reported. A genotype-phenotype correlation is not established, but atypical phenotypes have been described mainly in non-p.Tyr329Ser pathogenic variants.

We describe an atypical case in a 62-year-old Portuguese woman, presenting the typical clinical triad of APBD plus prominent autonomic dysfunction, suggested by orthostatic hypotension and thermoregulatory dysfunction; she has compound heterozygous GBE1 mutations, namely, p.Asn541Asp (c.1621A>G) and p.Arg515Gly (c.1543C>G), the last one not yet reported in literature and whose pathogenicity was suggested by bioinformatics analysis and confirmed by sural nerve biopsy that showed intrats with atypical phenotypes.

The current study set out to compare the efficacies and toxicities (grad 3 and 4) between concurrent chemoradiotherapy (CCRT), induction chemotherapy plus radiotherapy (IC + RT), IC + CCRT, RT and CCRT + adjuvant chemotherapy (CCRT + AC) in regard to advanced nasopharyngeal carcinoma (NPC) treatment using a network meta-analysis.

Literature retrieval was conducted using PubMed, Cochrane Library and other English databases. Eligible randomized controlled trails (RCTs) of 5 different regimens were included. The network meta-analysis combined direct and indirect comparisons to measure pooled odd ratios (OR) and the surface under the cumulative ranking curves (SUCRA).

A total of eight eligible RCTs were enrolled into this network meta-analysis after initial exclusion. With respect to hematologic toxicity, CCRT + AC exhibited higher toxicity in patients with advanced NPC in terms of anemia and leukopenia/neutropenia compared to RT. As for anemia, the toxicity of IC + CCRT was higher than those with advanced C + RT may be a potentially acceptable treatment alternative to CCRT for advanced NPC, and is worthy of further investigation.

Ballooned hepatocytes (BH) are akey histological hallmark of nonalcoholic steatohepatitis (NASH), yet their consequences for liver-specific functions are unknown.

In our previous study, an experimental model of human induced-BHs (iBH) has been successfully developed based on cell sheet technology. This study aimed to determine the functions of iBHs in the primary human hepatocyte/normal human dermal fibroblast (PHH/NHDF) co-culture cell sheets. Normal hepatocytes in the PHH/3T3-J2 co-culture cell sheets were set as a control, since 3T3-J2 murine embryonic fibroblasts have exhibited previously long term maintenance of PHH functions.

It was found that, albumin secretion was not affected in iBHs, but urea synthesis as well as cytochrome P450 enzyme (CYP) activities including CYP1A2 and CYP3A4, were significantly reduced in iBHs. Besides, loss of bile canaliculi was observed in iBHs. These findings are consistent with clinical studies of human NASH. In addition, PHH/NHDF cell sheets demonstrated twofold higher TGF-β1 secretion compared with PHH/3T3-J2 cell sheets. Furthermore, treatment with a TGF-β inhibitor and a semi-synthetic bile acid analogue (obeticholic acid, phase 3 trial of NASH therapy) ameliorated the histological appearance of established iBHs.

In summary, this study demonstrates the priority of iBHs in recapitulating not only histology but also clinically relevant hepatic dysfunctions in human NASH and suggests TGF-β and bile acid related signal pathway may play important roles in the formation of iBHs.
