Objective To analyze the influence of multiple myeloma tumor-associated gene MYEOV2 on NIH/3T3 cells growth. Methods The recombinant plasmid, pcDNA3.1(+)/MYEOV2, was constructed and subsequently transfected into NIH/3T3 cells by liposome. The positive clones of the transfected NIH/3T3 cells were obtained by G418 selection. RT-PCR was used to detecte the expression of MYEOV2 gene in the cells. Fluorescence-activated cell sorting (FACS) and cell grow curve drawing were applied to analyze the influence of MYEOV2 gene on NIH/3T3 cells proliferation. Results The cell clones stably expressing MYEOV2 gene were obtained. FACS analysis showed that the percentage of S phase cell of pcDNA3.1(+)/MYEOV2-transfected cells, pcDNA3.1(+) -transfected cells and non-transfected cells was 30.9%, 20.1% and 16.1%, respectively, and the difference of sphase cell percentage between pcDNA3.1(+)/MYEOV2-transfected cells and the other two groups of cells was significant (P

Objective To investigate the clinical and electrophysiological characteristics of upper motor neuron-dominant amyotrophic lateral sclerosis (UMN-D ALS ).Methods The clinical and electrophysiological characteristics were analyzed retrospectively in 76 patients with UMN-D ALS and 19 patients with primary lateral sclerosis (PLS).Electrophysiological study included the examination of median nerve,ulnar nerve,tibial nerve,peroneal nerve and sural nerve except for the electromyogram of bulbar region,cervical region,thoracic region and lumbosacral region.Results The diagnosis in 8 PLS patients were changed to UMN-D ALS after detailed review.In UMN-D ALS patients,there were more females in age group of older than 40 (male:female =1∶1.37) and 32 patients (38.1％) had onset with bulbar dysfunction.UMN-D ALS patients showed electromyograph evidence of denervation at 30 months (median)after onset,and clinical lower motor neuron (LMN) signs 6 months later.Seventy-seven patients (91.6％)developed LMN sign by 4 years from symptom onset.ALS functional rating score-revised changed from 40 ±3 to 32 ±4 in 4 years in U MN-D ALS patients (t =1.83,P ＜ 0.05 ).The amplitude of motor unit action potential (MUAP) on the first interosseus dorsalis was higher (( 1003.7 ± 25.2) μV vs (353.5 ±21.5) μV,t=2.34,P ＜0.05) and the duration of MUAP was longer ((19.8 ±2.3) ms vs (9.6 ±1.3) ms,t =1.85,P ＜0.05 ) in UMN-D ALS patients than in PLS patients.Conclusions UMN-D ALS occurs more in female cases,with more bulbar onset and with faster progression than PLS does.It also presents focal denervation in electromyograph.

Objective To explore surgical methods and their efficacy for post-traumatic Made-lung deformity complicated with dorsal or volar angulation in the adults. Methods Volar plate or exter-nal fixator, combined with the techniques osteotomy and bone grafting, were selected to treat adult pa-tients with post-traumatic Madelung deformity complicated with dorsal or volar angulation. The effects were preliminarily evaluated through comparing the volar tilting angle, ulnar inclination, radial shortening and the range of joint motion before and after the operation. Results All the patients were followed up for 6-27 months (mean 16 months). The volar tilting angle, radial inclination, radial shortening, range of joint motion of all patients were improved significantly (P<0.05). Conclusions For patients with Madelung deformity complicated with dorsal angulation, internal fixation of volar plate combined with volar osteotomy and bone grafting is recommended; while dynamic eternal fixator combined with combined with dorsal osteotomy and bone grafting is an ideal choice for patients with Madelung deformity complicated with volar angulation.

Objective To investigate the efficacy of biphasic insulin aspart 50(BIAsp50)twice daily(bid) versusbiphasichumaninsulin50(BHI50)(bid)plusmetforminonbloodglucosecontrolfollowingastandardmealtest in Chinese patients with type 2 diabetes mellitus(T2DM). Methods A randomized, open-label, 2-sequence, crossover trial for two 4-week treatment periods was conducted in 14 Chines institutes. Eligible subjects inadequately controlled with BHI50(bid)plus metformin were randomized to two sequences in a 1 : 1 ratio(A:BIAsp50-BHI50, B:BHI50-BIAsp50 ) . Standard meal tests were performed at baseline and the ends of two periods within 4 weeks. Primary endpoint was 2h postprandial plasma glucose ( PPG) increment following standard meal test, with insulin dose standardized at 0. 3 IU/kg. Results A total of 161 subjects were randomized into two sequences(81 to sequence A, and 80 to sequence B) and finally analysed. After 4 weeks of treatment, mean 2h PPG increment with BIAsp50 was lower than that with BHI50 [ treatment difference of BIAsp50 vs BHI50: -1. 12 mmol/L ( 95% CI-1. 66,-0. 58), P<0. 01], suggesting superiority of BIAsp50 over BHI50. Incremental area under the curve for PPG(0-2 h)with BIAsp50 was lower than that with BHI50 [treatment difference:-38. 8 mmol·L-1·min-1(95%CI-77. 3,-0. 26), P=0. 049], as was the mean 2h PPG [treatment difference:-0. 58 mmol/L(95% CI -1. 13,-0. 03), P=0. 040]. The FPG value with BIAsp50 was higher than that with BHI50 [treatment difference:0. 52 mmol/L(95%CI 0. 18, 0. 86), P=0. 003]. The rate of nocturnal hypoglycemia with BIAsp50 was lower than that with BHI50(1. 13 vs 2. 86 events per subject year, P<0. 01). Conclusion In patients with T2DM inadequately controlled with BHI50 plus metformin, BIAsp50 was proven to be well-tolerated with improved postprandial glucose control compared with BHI50.

Objective:To analyze the characteristics of cardio-metabolic risk factors coronary artery disease(CAD)patients with in-stent restenosis(ISR)after percutaneous coronary intervention(PCI).Methods:A total of 169 patients undergone primary(T1)PCI and followed up and rechecked by coronary angiography(T2)in our hospital from 2010 to 2017 were enrolled.According to the results of coronary angiography during follow-up, patients were divided into the ISR group(n=66)and the control group(non-ISR or NISR, n=103). Patients were sub-grouped into the elderly ISR group(the E-ISR group, n=17), the elderly non-ISR group(the E-NISR group, n=19), the young ISR group(the Y-ISR group, n=49)and the young non-ISR group(the Y-NISR group, n=84). Clinical data including medical history, laboratory results, and coronary angiography records during the two hospital stays were collected.Cardio-metabolic risk factors and clinical features of coronary artery disease were analyzed for the groups.Results:The levels of systolic blood pressure, glycated hemoglobin A1c(HbA1c), fasting blood glucose(FBG), the percentage of patients with diabetes or myocardial infarction(MI)history, the coronary Gensini score and the percentage of patients with triple vessel disease were higher in the ISR group than in the NISR group(128.6±16.4) mmHg vs.(123.4±10.7) mmHg, P=0.023; (7.0±1.6)% vs.(6.2±0.9)%, P<0.001; 6.6 mmol/L vs.5.7 mmol/L, P<0.001; 53.0% vs.31.1%, P=0.004; 36.4% vs.20.4%, P=0.022; 40 vs.29, P=0.01; 57.6% vs.40.8%, P=0.033). The E-ISR group had higher systolic blood pressure and a lower glomerular filtration rate than the E-NISR group(135.9±27.2) mmHg vs.(124.1±10.8) mmHg, P=0.013; 77.5±14.4 ml·min -1·1.73 m -2vs.(84.8±9.4) ml·min -1·1.73 m -2, P=0.033), but the Y-ISR group had longer hypertension history, higher levels of low-density lipoprotein and HbA1c, and higher Gensini scores than the Y-NISR group[129.7 months vs.83.1 months, P=0.008; (2.78±1.08) mmol/L vs.(2.31±0.65) mmol/L, P=0.002; (7.2±1.7)% vs.(6.1±0.9)%, P<0.001; 41 vs.29, P=0.009]. Conclusions:Clinical features are different between elderly CAD patients and young and middle-aged CAD patients with ISR after PCI, and metabolic risk factors such as blood pressure, blood lipid and blood glucose levels should be proactively controlled
