Objective To investigate the relationship between apolipoprotein E(Apo E) gene poly-morphism and mild cognitive impairment (MCI) in patients with type 2 diabetes mellitus (T2DM), and e-valuate the correlative risk factors. Method 40 cases of type 2 diabetes with MCI and 80 cases of type 2 diabetes without MCI were enrolled in this study. The polymorphism of the Apo E gene was detected by PCR-restriction fragment length polymorphism(PCR-RFLP). According to the clinical data such as course of disease, plasma glucose, plasma fat and body mass index (BMI), the independent risk factors of T2DM and MCI were analyzed by non-conditional logistic regression. Results The frequency of Apo E ε_4 allele in the group of type 2 diabetes with MCI was higher than that without MCI ( 25.0% vs 10. 0% ), and the difference had statistical significance( P < 0. 01 ). The indexes of the statistical significant difference be-twcen the two groups were age, course of disease, postprandial blood glucose ( P2BG), HBA1C, BMI,family history of T2DM, hypertension, diabetic retinopathy, diabetic peripheral neuropathy, Apo E gene. The independent risk factors included diabetic retinopathy ( OR = 3. 452, P < 0. 05 ), diabetic peripheral neuropathy( OR = 3. 252, P <0. 05), Ape E gene( OR = 2. 441, P < 0.01 ), HBA1C ( OR = 1. 372, P <0.05), P2BG(OR = 1. 194, P <0.05), age(OR = 1. 194, P <0.01) and course of disease(OR =1. 142, P <0. 05). Conclusion Apo E ε_4 allele has significant relationship with T2DM and MCI. The age, course of disease, control of plasma glucose, and microvascular complication of diabetes have relation-ship with the cognitive function.

Objective To evaluate the effectiveness of bioelectrical impedance analysis(BIA) interventions on volume status in hemodialysis patient. Methods Searched The Cochrane Library, PubMed, EMbase, EBsco, Wanfang Data, China Biology Medicine, China National Knowledge Infrastructure to collect clinical trials. The retrieval time was from database to July 15, 2016. The studies were selected according to the inclusion and exclusion criteria and were critically appraised by two reviewers. Then the data of included studies were extracted. Meta-analysis was conducted by using RevMan 5.3 software and descriptive analysis. Results Ten clinical trials were included six random control trial, one controlled clinical trail, three longitudinal study, involving 2009 patients. The results of Meta-analysis showed that the effectiveness of BIA interventions on volume management could improve blood pressure (P=0.001), protect the heart function(left ventricular mass index,P=0.002), compared with the clinical evaluation method, the BIA assessment of dry weight of hemodialysis patients could reduce hospitalization rate 14%. Descriptive analysis showed that BIA intervention volume management had certain advantages for the survival benefit of patients, but the current research was still few, had not yet come to a certain conclusion. Conclusions BIA can improve the management of the volume status and dry weight of hemodialysis patients, so as to it can improve the clinical benefit and survival benefit of patients.Better methods and guidelines for assessing DW and using BIA need to be developed.We propose that experienced HD nursing staff be trained in the use of the BIA to help monitor patient over hydration and approximate dry weight in consultation with the nephrologists responsible for the care of these patients so as to obviate excessive residual over hydration between nephrology reviews.

OBJECTIVE: Mitochondrial deoxyribonucleic acid (mtDNA) 8344 A>G (m.8344A>G) mutation is the common mutation associated with mitochondrial myoclonus epilepsy with ragged-red fibers (MERRF) syndrome. Herein we report a rare case with mitochondrial encephalopathy, lactic acidosis and stroke-like episodes/MERRF/Leigh (MELAS/MERRF/Leigh) overlap syndrome caused by m.8344A>G mutation. METHODS: The clinical and imaging data of the patient were collected and an open muscle biopsy was carried out. We further employed molecular genetic analyses to detect mtDNA mutation in the proband and his mother. And then a clinical and neuroimaging follow-up was performed. RESULTS: This patient was a 25-year-old male, who developed exercise intolerance since the age of 6. At age 10, he suffered from acute episodes of hemianopia, and cranial magnetic resonance imaging (MRI) showed occipital stroke-like lesions and cranial magnetic resonance spectroscopy (MRS) revealed a lactate peak corresponding to the lesion. After that the patient presented slowly progressive psychomotor decline. He had myoclonic seizures and cerebellar ataxia since the age of 12. At age 21, he was admitted to our hospital because of confusion and cranial MRI revealed symmetrical lesions in bilateral posterior putamen, thalami and midbrain. Then repeated MRI showed progression of original lesions and new frontal multiple stroke-like lesions. Symptomatic and rehabilitation treatment relieved his condition. Follow-up cranial MRI at age 24 showed the lesions in basal ganglia and thalami diminished, and the midbrain lesions even completely vanished. Muscle pathology indicated the presence of numerous scattered ragged-red fibers (RRF), suggestive of a mitochondrial disorder. Polymerase chain reaction-restricted fragment length polymorphism (PCR-RFLP) detected the m.8344A>G mutation of the MT-TK gene encoding mitochondrial transfer RNA for lysine in the patient's blood. Next generation sequencing (NGS) of the whole mitochondrial genome identified that the proportion of m.8344A>G was 90%, and no other mtDNA mutation was detected. Sanger sequencing further identified this mutation both in the proband and his mother's blood, although the mutation load was much lower in his mother's blood with approximately 10% heteroplasmy. CONCLUSION The present study is the first to describe a patient with m.8344A>G mutation in association with the MELAS/MERRF/Leigh overlap syndrome, which expands the phenotypic spectrum of the m.8344A>G mutation.
