Objective The aim of this study was to investigate the characteristic of regional cerebral glucose metabolism in patients with Wilson's disease (WD) using 18F-fluorodeoxyglucose (FDG) PET.Methods Thirteen WD patients and 12 normal controls were studied by brain 18F-FDG PET, and the data were analyzed by visual analysis, semi-quantification and statistical parametric mapping (SPM). The radioactivity ratios of lenticular nuclei, caudate, thalamus and cerebellum to cerebral cortex and the ratio of lenticular nuclei to caudate were calculated, respectively. SPSS 11.0 software for statistics was also used to analyze the data. Results In WD patients, radioactivity of lenticular nuclei and candate was significantly decreased compared with controls. The radioactivity ratios of lenticular nuclei and caudate to cerebral cortex in WD patients were both significantly lower than that in normal controls (0.95±0.05 vs 1.26±0.05, t =15, P < 0.05 ; 1.02±0.06 vs 1.17±0.05, t = 8, P < 0.05), and the ratio of lenticular nuclei to caudate in WD patients was significantly higher than that in normal controls (0.93±0.06 vs 1.09±0.06, t =9, P< 0.05). Conclusion As compared with normal controls, patients with WD had significantly decreased glucose utilization in the basal ganglia, especially in the lenticullar nuclei.

Patients with early cataract may have normal visual acuity ( VA ) but complain that they have problems in driving at night, like seeing things through a veil. This phenomenon is defined as disability glare which maybe caused by growing stray light. Patients with intraocular lens following cataract surgery may complain about glare, halos and shadows in visual field, which are also resulted from dysphotopia. Disability glare is the VA loss due to disturbing luminance in visual field. ln other words, it's the retinal contrast sensitivity reduction because of the straylight. This article contains the consensus and new progress of disability glare. lt provides solutions according to its effect factors and offers clues for further study.

As one of the major sources of infection, viruses could infect all organisms including bacteria, plants, animals, and humans. Infectious diseases caused by viruses pose a great threat and damage to human health and economic activities all over the world. Adaptor-associated protein kinase 1 (AAK1) is a member of the Ark1/Prk1 family of serine/threonine kinases and a specific key kinase regulating the phosphorylation of AP-2 protein μ2 subunit T156. In the past, AAK1 has been regarded as a feasible biological target for the treatment of nerve pain. Recently, scientists have found that inhibiting AAK1 can regulate endocytosis and inhibit virus invasion into cells. Therefore, AAK1 could be the potential target of anti-virus therapy. This paper reviews the research progress of small molecule AAK1 inhibitors in the field of antiviral, analyzes the future research directions and challenges, and provides new ideas for the development of antiviral drugs targeting AAK1.

OBJECTIVETo study the effect of dihydroartemisinin (DHA) combined irradiation on the apoptosis of human lung cancer GLC-82 cells and to study its mechanism.
METHODSThe growth inhibition rate of GLC-82 cells acted by different concentrations DHA was detected using MTT assay at 24, 48, and 72 h, respectively. Clone forming test was used. With multi-target single-hit model, the radiosensitization effect was assessed by calculating sensitizing enhancement ratio (SER).The effect of DHA combined irradiation on the apoptosis of GLC-82 cell cycle distribution and apoptosis were measured by flow cytometry. The protein expression of p53, p21, Bcl-2, and Bax were detected by Western blot.
RESULTSDifferent concentrations DHA (4, 8, 16, 32, 64, and 128 μg/mL) had cytotoxicity on GLC-82 cells. The IC50 for 24, 48, and 72 h was 38.25,20.58, and 10.36 μg/mL, respectively, in obvious dose- and time-dependent manner. The growth inhibition rate was more significantly increased than that of the blank control group (P < 0.01, P<0.05). DHA had sensitization enhancement effect on GLC-82 cells, with SER of 1.4. DHA combined irradiation could obviously change the structure of GLC-82 cells cell cycle and induce apoptosis (with the apoptosis rate of 21.5%), which was significantly different from that of the blank control group (P < 0.05). Western blot showed the expression of p53 and p21 protein could be increased by DHA combined irradiation, and the expression of Bcl-2 protein down-regulated (P <0.01, P <0. 05).
CONCLUSIONSDHA had stronger cytotoxicity and radiosensitization on GLC-82 cells. Its mechanisms might lie in making the arrest of GLC-82 cells' growth at G0/G1 phase, decreasing the ratio of cells at S phase, restoring the function of p53, decreasing the expression of Bcl-2 protein, and inducing apoptosis in GLC-82 cells.

BACKGROUNDThe molarless condition has been reported to compromise learning and memory functions. However, it remains unclear how the molarless condition directly affects the central nervous system, and the functional consequences on the brain cortex and hippocampus have not been described in detail. The aim of this study was to find the molecular mechanism related with learning and memory deficit after a bilateral molarless condition having been surgically induced in senescence-accelerated mice/prone 8 (SAMP8) mice, which may ultimately provide an experimental basis for clinical prevention of senile dementia.
METHODSMice were either sham-operated or subjected to complete molar removal. The animals' body weights were monitored every day. Learning ability and memory were measured in a water maze test at the end of the 1st, 2nd, and 3rd months after surgery. As soon as significantly prolonged escape latency in the molarless group was detected, the locomotor activity was examined in an open field test. Subsequently, the animals were decapitated and the cortex and hippocampus were dissected for Western blotting to measure the expression levels of brain-derived neurotrophic factor (BDNF) and the tropomyosin related kinase B (TrkB), the high affinity receptor of BDNF.
RESULTSSlightly lower weights were consistently observed in the molarless group, but there was no significant difference in weights between the two groups (P > 0.05). Compared with the sham group, the molarless group exhibited lengthened escape latency in the water maze test three months after surgery, whereas no difference in locomotor activity was observed. Meanwhile, in the cortex and hippocampus, BDNF levels were significantly decreased in the molarless group (P < 0.05); but the expression of its receptor, TrkB, was not significantly affected.
CONCLUSIONThese results suggested that the molarless condition impaired learning and memory abilities in SAMP8 mice three months after teeth extraction, and this effect was accompanied by significantly reduced BDNF expression in the cortex and hippocampus.
