Objective To explore the levels of serum interleukin-6 and interleukin-18 in newly diagnosed type 2 diabetes mellitus (T2DM) and investigate their roles. Methods The serum interleukin-6 and interleukin-18 levels were detected in 50 newly, diagnosed T2DM patients (T2DM group) and 40 normal subjects (control group). Fasting blood glucose, fasting insulin, blood lipid, body mass index (BMI) and waist/hip ratio (WHR) were measured. HOMA-IR and HOMA-β were calculated. Results The serum interleukin-6 and interleukin-18 levels in T2DM group were significantly higher than those in control group [(2.56 ± 1.09) ng/L vs (1.81±0.80) ng/L, (5.38±0.91) ng/L vs (4.62±0.59)ng/L] (P <0.01).Interleukin-6 level was positively correlated with HbA_1c,while interleukin-18 level was positively correlated with BMI and WHR. Interleukin-6 and interleukin-18 levels were positively correlated. Interleukin-6 and interhukin-18 could predicted the insulin resistance. Conclusion Interleukin-6 and interleukin-18 take part in the development of T2DM, and can be related to the insulin resistance.

Insulin resistance is the important base of the pathogenesis of type 2 diabetes.Physical exercise can improve insulin sensitivity.This article presents an overview of how physical exercise improves insulin resistance and helps the prevention and treatment of diabetes mellitus by analyzing its influence on the level of insulin receptor and post-receptor and adipose cell cytokine.

Objective To study the clinical features and treatment of horizontal canal benign paroxysmal positional vertigo (HC-BPPV).Methods The clinical features of 27 patients with HC-BPPV and the treatment results with otolith repositioning maneuver of Barbecue rotation were analyzed retrospectively.Results All the patients with HC-BPPV had vertigo attack and this kind of vertigo attack presented with some characters such as brief, positioning, latency and no fatigability. Geotropic nystagmus was seen in 21 patients and apogeotropic nystagmus was seen in 6 patients when head was turned to either side in supine position. After Barbecue rotation, all symptoms disappeared in patients with geotropic nystagmus and did not change in patients with apogeotropic nystagmus.Conclusions The diagnosis of HC-BPPV is based on typical clinical features and test of turning head to either side in supine position. Geotropic nystagmus is associated with canalithiasis and apogeotropic nystagmus is associated with cupulolithiasis, and the therapy of Barbecue rotation is very effective to HC-BPPV patients with geotropic nystagmus.

Objective To assess the diagnosis value of epithelial membrane antigen (EMA) immunocytochemistry examination in meningeal carcinomatosis.Methods The routine cerebrospinal fluid cytologic examination and EMA immunocytochemistry examination of 23 cerebrospinal fluid specimens from 14 patients with definitive meningeal carcinomatosis were analyzed,retrospectively.Results The positive rate of routine cerebrospinal fluid cytologic examination and EMA immunocytochemistry examination were 39.13%(9/23)and 86.96%(20/23),respectively. There was a significant difference between two results ( P

Objective To evaluate the clinical features and treatment of posterior semicircular canal benign paroxysmal positional vertigo(PC-BPPV).Methods To retrospectively analyse the clinical features and therapy results of 120 patients with PC-BPPV from January 2003 to November 2004 in the Chang Zheng Hospital of the Second Military Medical University.Results Vertigo attack of PC-BPPV had such characters as brief period,positioning,latency and fatigability.Geotropic rotatory nystagmus occurred in 108 patients and apogeotropic rotatory nystagmus in 12 patients in the test of Dix-Hallpike,and the former received the repositioning maneuver therapy of Epley and the later received the therapy of Semont maneuver.The symptoms disappeared completely in 88 patients after a single session and 12 patients after twice、6 patients after triple sessions of Epley repositioning maneuver therapy in the former,no effectiveness in 2 patients;the symptoms remitted in 8 patients after once,2 patients after twice and 1 patient after triple sessions therapy of Semont repositioning maneuver in the later,no change in 1 patient.The total success rate was 97.5%(117/120).Fifteen patients had relapse during follow-up and the recurrence rate was 12.5%(15/120).They also responded to repositioning maneuver therapy.Conclusion The diagnosis of PC-BPPV is based on the typical clinical features and the test of Dix-Hallpike.The repositioning maneuver therapy is safe and effective for PC-BPPV and should be used for all patients when the diagnosis is clearly made.

Banana streak virus (BSV),a member of genus Badnavirus,is a causal agent of banana streak disease throughout the world.The genetic diversity of BSVs from different regions of banana plantations has previously been investigated,but there are relatively few reports of the genetic characteristic of episomal (non-integrated)BSV genomes isolated from China.Here,the complete genome,a total of 7722bp (GenBank accession number DQ092436),of an isolate of Banana streak virus (BSV) on cultivar Cavendish (BSAcYNV) in Yunnan,China was determined.The genome organises in the typical manner of badnaviruses.The intergenic region of genomic DNA contains a large stem-loop,which may contribute to the ribosome shift into the following open reading frames (ORFs).The coding region of BSAcYNV consists of three overlapping ORFs,ORF 1 with a non-AUG start eodon and ORF2 encoding two small proteins are individually involved in viral movement and ORF3 encodes a polyprotein.Besides the complete genome,a defective genome lacking the whole RNA leader region and a majority of ORF1 and which encompasses 6525bp was also isolated and sequenced from this BSV DNA reservoir in infected banana plants.Sequence analyses showed that BSAcYNV has closest similarity in terms of genome organization and the coding assignments with an BSV isolate from Vientam (BSAcVNV).The corresponding coding regions shared identities of 88％ and ～95％ at nucleotide and amino acid levels,respectively.Phylogenetic analysis also indicated BSAcYNV shared the closest geographical evolutionary relationship to BSAcVNV among sequenced banana streak badnaviruses.

Objective To discuss the clinical features of pregnant women with hypertrophic cardiomyopathy (HCM).Methods There were 28 patients with HCM who delivered in Renji hospital of Shanghai Jiaotong University from January 2000 to August 2012.Clinical data were analyzed,including diagnosis,cardiac functional grading,gestational weeks of delivery,delivery mode,birth weight,Apgar scores,etc.Results (1) Of all the 28 patients,14 (50％) were diaguosed before pregnancy and others (50％) were diagnosed during pregnancy.(2) Four cases were obstructive HCM (14％),3 with cardiac function grade Ⅰ and 1 with grade Ⅱ.Twenty four cases were non-obstructive HCM (86％),14 with cardiac function grade Ⅰ,9 with grade Ⅱ and 1 with grade Ⅳ.(3) Of all the 28 patients,4 had family history,18 (64％) had clinical symptoms or signs which occurred in 8-32 gestational weeks.Twenty-three cases had abnormal ECG (82％).Among them 21 had non-obstructive HCM (88％),with average interventricular septal thickness of(22 ± 3) mm.The other 2 patients had obstructive HCM,with average interventricular septal thickness of (23 ± 4) mm.7 patients (7/28,25 ％) had mild-to-moderate pulmonary hypertension [6 with non-obstructive HCM (6/24,25％)],and 10 patients had abnormal myocardial enzyme spectrum or troponin levels [9 with non-obstructive HCM (9/24,38％)].(4) Among all the patients,only one had vaginal delivery and others received cesarean section.Twenty-two patients had term pregnancies and 6 had preterm birth.The average gestational weeks of delivery in non-obstructive HCM and obstructive HCM were (36.5 ± 2.5) and (38.5 ± 0.4) weeks,respectively.The average birth weight of neonates were (2684 ± 563) and (3164 ± 321) g,and Apgar scores were 9.9 and 10 (10 minutes) respectively.Patients transferred to NICU after delivery were 8 and 0.There was 1 maternal death(with nonobstructive HCM whose ejection fraction was only 26％) and no perinatal death.Conclusions More attention should be paid to the clinical signs and abnormal ECG.HCM could be definitely diagnosed by timely echocardiography.Patients with hypertrophic cardiomyopathy were mainly non-obstructive HCM,with cardiac function grade Ⅰ and Ⅱ.Monitoring the change of ejection fraction during pregnancy would help.Perinatal outcomes were fine.

OBJECTIVE: The purpose of this study is to assess the effects of aging on air-conducted sound elicited cervical vestibular evoked myogenic potential (cVEMP) and ocular vestibular evoked myogenic potential(oVEMP) in normal people. METHOD: Sixty normal subjects were recruited for the vestibular evoked myogenic potential examination. Among them, 20-40 year-old group was setted as the first group, 41-60 year-old group was setted as the second group, > 60-year-old group was setted as the third group. Each group included 20 normal subjects. SPSS 16.0 software was used to analyze the data. RESULT: As the age growing, P1 latency prolonged, N1-P1 amplitude decreased, and amplitude asymmetric ratio increased in cVEMP; N1 latency prolonged, P1-N1 amplitude decreased, and amplitude asymmetric ratio increased in oVEMP. CONCLUSION With the age growing, the time of otolithic organ input pathways prolonged, the function of otolithic organ decreased and the decrease level may be asymeetrical on both sides.

Objective To explore the clinical features of vestibular paroxysmia (VP).Methods The clinical features of 51 patients with VP from January 2009 to April 2011 were analyzed retrospectively.The treatment effectiveness of antiepileptics was evaluated.Results The ratio of male to female was 1 ∶ 1.55 in the 51 patients with VP and the course of disease was 10 days to 20 years.In 46 patients (90.2％) the attacks occurred at rest,whereas 37 patients (72.5％) were precipitated by a head turn or a body turn.Three minutes hyperventilation-induced vertigo was found in 13 patients (25.5％) and Fukuda test was positive in 15 patients (29.4％).Forty patients (78.4％) were abnormal in brainstem auditory evoked potentials (BAEP) and the interpeak latency of wave Ⅰ-Ⅲ was prolonged than 2.2 ms in 26 patients (51.0％).There were 47 ears had neurovascular cross-compression (NVCC),which were unilateral in 37 patients and bilateral in 5 patients,with type Ⅰ in 23 ears(48.9％),type Ⅱ in 5 ears(10.6％),type Ⅲ in 17 ears(36.2％) and type Ⅳ in 2 ears(4.3％).Three month-treatment led to a significant reduction in the attack frequency(3 (2,7) per month vs 15 (9,30) per month,Z =-6.156,P ＜ 0.01),in the attack duration(2(1,4) s vs 12(6,20) s,Z =-6.066,P ＜0.01),and a reduction in the visual analogue scale of vertigo (1.86 ±0.57 vs 5.83 ± 1.12,t =1.984,P ＜ 0.01).Conclusions Briefvertigoattacksatrestis the character of VP.Three minutes hyperventilation-induced vertigo is helpful for the diagnosis of VP.The prolongation of the interpeak latency of wave Ⅰ-Ⅲ in BAEP is the character of VP.NVCC widely existed in the patients with VP and types Ⅰ and type Ⅲ was more common.Using antiepileptics,a better treatment effectiveness can be obtained.

Aim To investigate the effect of BMS- 345541 on the repair of DNA DSBs induced by VP-16 in AML cells and its possible mechanism. Methods The effects of BMS-345541 on the sensitivity of AML cells to VP-16 were determined by MTT. Flow cytome-try ( FCM) was applied to test the level of DNA dam-age, cell cycle progression and apoptosis in AML cells. High content analysis ( HCA) was used to verify the amount ofγ-H2AX,p-ATM,RAD51 in AML cells. Results BMS-345541 could significantly inhibit the proliferation of AML cells induced by VP-16 . BMS- ＜br> 345541 increased the amount of RAD51 foci and p-ATM foci in AML cells treated with VP-16 after 6 hours , which led to increased numbers of cells in the G2/M phases of the cell cycle,then induced apoptotic cell death. Conclusion BMS-345541 sensitizes AML cells to VP-16 via selective inhibition of homologous recombinational repair of DNA double-strand breaks.
