Objective To investigate the relationship between positron emission tomography (PET) and cognitive dsyfunction in patients with multiple sclerosis (MS). Methods 2 cases of MS were test with the Wechsler Intelligence Scale (WIS) or mini-mental state examination(MMSE), brain MRI and PET,then the results were analysed. Results The MMSE score of the case 1 was 19, which was lower than normal. The WIS score of the case 2 was normal. The PET of 2 patients showed that there were many hypo-metablism areas in cortex or subcortex.In addition,some cortical hypo-metablism areas of PET were not correspondingly found lesions in cortex or subcortex by MRI. Conclusions There are many hypo-metablism areas in cortex or subcortex in MS patients. The hypometablism areas may be correlated with the cognitive dysfunction of MS.

ObjectiveTo investigate the clinical,myopathological and molecular changes in two Chinese families with oculopharyngodistal myopathy ( OPDM).MethodsWe performed muscle biopsy and histopathologic study on the probands of two families,and further examined molecular genetic testing on PABPN1 and GNE gene. Results Family 1 included 3 affected brothers in the same generation and family 2 involved 4 patients in 2 generations. Dysarthria rather than external ophthalmoplegia was the prominent oculopharyngeal symptoms for Chinese patients. No intranuclear inclusions were observed in ultrastructural examination.The number of GCG repeats in the PABPN1 gene was within normal range and no mutations were identified in the GNE gene.ConclusionsFamily 1 is the first publication on autosomal recessive OPDM in China.The age of onset of two families was comparable with Japanese patients and the pattern of muscle involvement was different. OPDM is a distinct phenotypical,histological,and genetic entity.

This study was aimed to evaluate the feasibility of wind-warm lung-heat disease (non-severe community-acquired pneumonia, CAP) from the clinical curative effect, hospitalization days, medical expenses and other aspects. This study selected 198 wind-warm lung-heat disease (non-severe CAP) inpatients from January, 2012 to December, 2012 with the conventional therapy in the Respiratory Department, Wuhan Integrated Traditional Chinese Medicine (TCM) & Western Medicine Hospital as the control group. And another 179 wind-warm lung-heat disease (non-severe CAP) inpatients were selected from January, 2013 to December, 2013 with the TCM clinical pathway treatment in the Respiratory Department of the same hospital as the treatment group. Retrospective analysis was used to compare the clinical curative effects, hospitalization days, and medical cost differences. The results showed that TCM clinical pathway for wind-warm lung-heat disease (non-severe CAP) can shorten the hospitalization days and reduce patients’ medical costs, and ensure the clinical curative effects. It was concluded that the standardized TCM clinical pathway had positive effect on wind-warm lung-heat disease (non-severe CAP). Therefore, the formulation and implementation of TCM clinical pathway was of great significance in the treatment of wind-warm lung-heat disease (non-severe CAP).
