Journal of Leukemia & Lymphoma 2016;25(1):15-18
The diagnosis and treatment of multiple myeloma (MM) have make remarkable progress, which were reviewed in the 57th American Society of Hematology (ASH) annual meeting. In this annual meeting, the effects of advanced proteasome inhibitor (PI), antibody, checkpoint blockade, immunomodulatory agent (IMiD), histone deacetylase (HDACI) and chimeric antigen receptor T-cell (CAR-T), and new diagnostic technologies were reported. The real point is to apply the best available diagnosis and therapy at this meeting. At present, regardless of advances, all of randomized clinical trials push to combined agents, and combined with hematopoietic stem cell transplantation, efficacy will be improved in further. So some professors also refered to 2015 year as 'the advance year of MM'.

AIM: To investigate the changes of bladder volume , pressures and pelvic nerve firing induce by different speeds and ways of instillation .METHODS:Female SD rats (n=20) were randomly divided into 2 groups.The rats in group A was performed using 3-F polyethylene tubing inserted into the bladder through the urethra .The rats in group B were performed using 3-F tubing inserted into the dome of the bladder and secured by silk suture .The rats in both groups were infused with saline into the bladder at different speeds of 50, 100, 200 and 400μL/min.The changes of bladder vol-ume and pressure were recorded by urodynamic measuring devices .The changes of pelvic nerve firing during instillation were recorded by multi-channel physiologic recorder .RESULTS:In group A, the maximum firing frequency , bladder leak point pressure ( BLPP) and maximum voiding pressure ( MVP) were increased with the increase in the instillation speed . No significant difference of the maximum bladder capacity (MBC) at different speeds was observed .In group B, the maxi-mum firing frequency had no significant difference at different speeds .MBC was decreased with the increase in the instilla-tion speed , and exhibited significant decrease at 200 and 400 μL/min.No significant difference of BLPP and MVP at dif-ferent speeds was observed .Compared with group A , the maximum firing frequency and MBC in group B significantly de-creased at different speeds .However , BLPP and MVP in group B were higher than those in group A at the speeds of 50 and 100 μL/min.CONCLUSION:Different instillation speeds with the method of group A will not change the bladder volume but influence the pelvic nerve firing , so the process of method A may take various speeds according to different aims .How-ever, process of method B at the speed of over 200 μL/min may not be good to MBC, thus instillation under 200 μL/min is re-commended .

Objective To investigate the attentional network in patients with temporal lobe epilepsy(TLE) and the disease-related factors. Methods Fity-four patients with TLE and 40 controls were enrolled in our hospital from January 2007 to December 2008.The computerized ANT software was used for evaluating the attentional network efficiency and the clinical date of the patients with TLE were recorded. Logistic regression was used to identify the risk factors of attentional network efficiency. Results The mean reaction time(TLE:688.2±138.1 ms;Control:625.1±100.1 ms, t=2.06, P <0.05)and executive control network efficiency (TLE:155.7±57.0 ms;Control:108.0±33.8 ms, t=4.62, P <0.01) of the TLE group were lower than the healthy control group. The efficiency of alerting network and orienting network between the two groups were no significant difference. Logistic regression analysis showed that the positive epileptiform activity was an independent risk factor of the attentional impairment(95% CI : 1.03~42.33, OR =6.603, P =0.043). Conclusions The ANT demonstrate that patients with TLE may accompany with attentional executive control network efficiency impairment. Epileptiform discharge may cause attentional executive network efficiency impairment.

A full-length cDNA sequence encoding for the precursor of a venom peptide (named BmKCT) with homology to chlorotoxin has been isolated from a cDNA library made from the venom glands of the Chinese Scorpion Buthus martensii Karsch. The sequence of BmKCT is similar (68 % identities) to that of chlorotoxin isolated from Leiurus quinquestriatus quinquestriatus. To understand the biological function of BmKCT, this peptide was expressed using pGEX expression system and purified using GST affinity column and gel filtration.Whole cell patch-clamping recording showed that BmKCT could significantly inhibit chloride currents of gliomas cells, and the inhibitory effect was reversible. These results suggested that BmKCT might belong to the class of short chain toxins blocking the chloride ion channels.

Objective To explore the effects of tumor necrosis factor-α (TNF-α) on ventricular arrhythmias resulted from acute myocardial infarction (AMI) in rats. Method Two hundred and forty male Wistar rats were randomized (random number) into sham operation group, AMI group and recombinant human tumor necrosis factor receptor (rhTNFR) fusion protein (Fc) group. Acute anterior wall myocardial infarction was produced in rats of AMI group with ligating the left anterior descending coronary artery (LAD) , and the rats were just operated without ligation of LAD in sham group. The rats of Fc group were treated with rhTNFR-Fc (10 mg/kg), a TNF-α antagonist, 24 hours before LAD ligation. The original ECG was recorded 10 min before ligation and the ECGs of ventricular arrhythmias occurred spontaneously or induced by programmed electrical stimulation were recorded 10 min, 20 min, 30 min, 60 min, 3 h, 6 h and 12 hours after ligation. The protein levels and mRNA expressions of TNF-α in rats in different groups were detected with histochemistry and real-time fluorescent quantitative PCR. Results The expressions of TNF-α mRNA and levels of TNF-α protein markedly increased 10 min after infarction, reached the climax 20-30 min later, and then gradually returned to the original level in AMI group and Fc group. The time-windows of spontaneous and induced ventricular arrhythmias were consistent with the time-window of expressions of TNF-α mRNA and levels of TNF-α protein. Compared with AMI group, there were lower levels of TNF-α protein and lower incidence of ventricular arrhythmias in Fc group ( P < 0.05) , but there was no significant difference in TNF-α mRNA between two groups. There was no obvious change in TNF-α in rats of sham operation group. Conclusions The expressions of TNF-α mRNA and levels of TNF-α protein induced by AMI could contribute the initiation of ventricular arrhythmias.
