ObjectiveTo investigate the association between CYP11B2 gene polymorphism and left ventricular hypertrophy in Chinese hypertensive patients by the means of meta-analysis. MethodsLiteratures about case control study on the association of CYP11B2 gene polymorphism and left ventricular hypertrophy were searched from January 1980 to December 2012.The electronic databases searched included China national knowledge internet,Chinese biological medicine disk,Vip fulltext database,Wanfang fulltext database and Pubmed.Odds ratio (OR) of CYP11B2 genotype distributions in left ventricular hypertrophy (LVH) patients against NLVH patients were analyzed.RevMan 5.1 software was applied for investigating heterogeneity among individual studies and summarizing effects across studies by proper statistical methods. ResultsSix case-control studies were selected finally.A total of 1 791 hypertensive patients were included.The pooled OR (95% CI) of CC vs.TT+TC genotype was 1.21(0.80,1.81)(Z=0.91,P=0.36),the pooled OR (95% CI) of (TC+CC) vs.TT genotype was 1.16(0.68,1.98)(Z=0.54,P=0.59),and the pooled OR (95% CI) of C vs.T allele was 1.09(0.78,1.54)(Z=0.51,P=0.61). ConclusionThe genotype of CYP11B2 polymorphism is not associated with an increase risk of left ventricular hypertrophy in Chinese hypertensive patients.
ObjectiveTo make a better understanding of potassium channel-complex autoimmune antibodies associated limbic encephalitis, we studied in details with patients of this autoimmune disease accompanying without tumors. MethodsDiagnosis of 3 patients were confirmed by antibody detection in serum or CSF. All the clinical data, including history, CSF data, cranial MRI, EEG, pelvic ultrasound and treatment strategy, were carefully gathered. Two to eleven months follow-up were carried out. Results3 female adult patients showed common initial manifestation of seizures, and changes of consciousness, mental disorder and cognitive impairment. Hyponatremia was found in one LGI1-Ab+ patient. Cranial MRI showed unilateral or bilateral signal changes with limbic system. Changes of CSF and EEG were nonspecific. All 3 patients became recovery in different levels after two to eleven months. ConclusionsPotassium channel-complex antibodies associated encephalitis may be a common type of limbic encephalitis in adults without tumors. Seizures may be the first sign of the disease. Hyponatremia is one of characteristics of LGI1-Ab+ patient. Patients may have a fairly good short outcome.
ObjectiveTo evaluate the role of cardiopulmonary bypass (CPB) technique in the treatment of the abdominal soft tissue tumor (ASTT). MethodClinical data of 9 patients with ASTT who underwent CPB-aided resection in zhongshan Hospital of Fudan University from April 2011 to December 2015 were analyzed retrospectively. ResultsAll patients were performed complete resection of tumor, without perioperative death. Six patients received complete CPB technique and other 3 patients received partial CPB technique. In establishment of CPB, patterns of arterial perfusion included the ascending aorta (n=6) and femoral artery (n=3); patterns of venous drainage included the inferior vena cava (n=2), superior vena cava (n=6), femoral vein (n=2), and jugular vein (n=3). Among of them, 7 patients were diagnosed as intravenous leiomyomatosis, 1 patient was diagnosed as small round cell malignant tumor, and another 1 patient was diagnosed as leiomyosarcoma. Two patients occurred postoperative complications, 1 patient was duodenal fistula, with conservative treatment to heal; another 1 patient was inferior vena cava thrombosis, with treatment of placement of the inferior vena cava filter. Nine patients received follow-up, and follow-up time was 1-57 months (the median time was 4-month), and the survival rate was 100%, no one suffered from recurrence. ConclusionsFor some patients with complicated ASTT, CPB technique can provide chance to completely resect the tumors.
ObjectiveTo study the clinical characteristics of patients onset epilepsy Dentatorubral-pallidoluysian atropy (DRPLA) in Epilepsy Center of Guangdong 999 Brain Hospital and improve understanding of the disease. MethodsCollected five patients from August 2014 to August 2016 in Guangdong 999 Brain Hospital, whom diagnosed through genetic testing of DRPLA, analysed their disease course, family history, video-EEG, brain MRI and treatment data. ResultsDRPLA performed as neurodegenerative diseases, and epilepsy population mainly performed as progressive myoclonic epilepsy (Progressive myoclonus epilepsy, PME). ConclusionDRPLA is autosomal dominant neurodegenerative disease. In patients with cerebellar atrophy, neurological regression, ataxia, drug refractory epilepsy, it is recommended routinely to detect ATN1 gene, so that timely diagnosis and genetic counseling.
ObjectivesPost-encephalitic epilepsy could be of great chance of pharmaco-resistant, even surgery may not achieve seizure free. The aim of this study is to mapping epileptogenic area of pharmaco-resistant post-encephalitic temporal lobe epilepsy, to find whether "temporal plus" epilepsy is the main type and its surgery outcome, based on stereo-EEG(SEEG) study.MethodWe retrospectively studied 15 patients with pharmaco-resistant temporal lobe epilepsy. Scalp EEG, seizure semiology, MRI, FDG-PET, and SEEG were reviewed for all patients. According to epileptogenic area which was analysed by SEEG, 15 patients were divided into 2 groups, temporal lobe epilepsy(TLE) group and temporal plus epilepsy(TPE) group. Clinical characteristics were compared with each group, by t-test or Fisher exact test when data needed.ResultsThere were 8 patients in TLE group, with 6 mesial TLE, 1 lateral TLE, 1 mesial-lateral TLE. And 7 patients in TPE group. Age of seizure onset (P=0.548), duration of epilepsy (P=0.099), age of remote encephalitis (P=0.385), type of semiology (P=0.315) and lateralization of MR lesions (P=1.000), interictal FDG-PET hypometabalism (P=1.000) or intracranial implantation (P=0.619) were of no statistically difference between TLE group and TPE group. Surgery was performed in all patients. Better outcome was obtained in TLE group(5/8 class Ⅰ), and poor was in TPE group(3/7class Ⅰ).ConclusionMesial-TLE and temporal plus epilepsy were common types of pharmaco-resistant post-encephalitic TLE. There was no way to differentiate clinically, except by SEEG. Mesial-TLE had a better outcome after surgery, but temporal plus epilepsy did not.
