Objective To explore effect of swan-like memory connector (SMC) on bioelectric potential changes during the course of experimental fracture healing and its relation with fracture healing. Methods Bilateral humerus of 33 New Zealand rabbits were osteotomized in midshaft. One random side was fixed with SMC and the other one plated by the four-hole dynamic compression plate (DCP). The bioelectric potential changes of the fractured humerus in eight animals were determined using modified Friedenberg's technique,at eight time intervals (prefracture,postfracture,postfixation immediately,1, 2,4,8 and 12 weeks after surgery). The rabbits were killed at the 1st,2nd,4th,8th and 12th weeks respectively postoperatively and the humerus in 5 rabbits harvested for HE sections. Results The bioelectric potential of fracture site remained invariably negative all the time in the Group SMC. However,the bioelectric potential began to recover from the 2nd week after operation and reached the normal level of prefracture at the 4th week in the Group DCP,with a significant difference compared with the Group SMC ( P

Objective To investigate the correlation between prognosis of patients with severe acute pancreatitis and changes of plasma albumin. Methods A total of 235 patients with severe pancreatitis who were admitted into hospital from September 2008 to October 2013 were selected as research object. According to the prognosis, they were divided into the survival group (143 cases who were recovered and still alive) and the death group (92 cases who died of the deterioration of diseases). Retrospectively analyzed the basic situation of the pa-tients and the changes of serum albumin levels in the two groups. And the correlation between prognosis of patients with severe acute pancrea-titis and changes of plasma albumin were evaluated by the logistic regression analysis. Results Compared with the death group,there were significant differences (P<0. 05) in terms of age,APCHEⅡ score,Ranson score,SOFA score,length of hospital stay,duration of mechani-cal ventilation,continuous renal replacement therapy,average serum albumin level,decrease of serum albumin within 24 hours,and variation of serum albumin. And ROC curves suggested the best cutoff value of decrease of serum albumin within 24 hours to predict death in patients within 24 hours was 4. 24 g/L,and the best cutoff value of variation of serum albumin to predict death was 13. 6%. Logistic regression analy-sis showed that the major risk factors of death in severe acute pancreatitis were decrease of serum albumin within 24 hours,variation of serum albumin within 24 hours,average serum albumin level,and the APCHEⅡscore. Conclusion Changes in plasma albumin can reflect the se-verity of severe acute pancreatitis,and the sharp decrease of serum albumin within 24 hours can be used as a risk factor for death.

Objective To explore the effects of swan-like memory compressive connector(SMC) made of Ni-Ti shape memory alloy on stress shielding rate, struct ure and mechanical properties as well as the blood flow of cortical bone of expe rimental fracture healing. Methods Mid-shaft osteotomies of bilateral humerus we re performed in 56 rabbits. One side was randomly fixed with SMC, and the other side was plated with a 4-holes dynamic compressive plate (DCP). At 2, 4, 8, 12, 16,and 20 weeks after operations, the humeri in 8 rabbits were harvested. The st ress-shielding rate was measured using axial compressive test in situ samples. T he geometrical structure and bone density were examined by CT scans, and the mec hanical property was assessed by torsion tests. Blood flow was measured in real time using Laser-Doppler flowmetry. The cortical bone perfusion of 16 rabbits wa s measured at 10 time intervals (after periosteotomy, after fracture, instant af ter fixation, at 1, 3, and 7 days, and 2, 4, 8, and 12 weeks postoperatively). B lood flow was measured at outer and inner cortical bone beneath the fixation. Si multaneously, anteroposterior radiograph of the humerus was taken. Results The s tress-shielding rate in SMC group was significantly lower than that of DCP group (P

Objective To investigate the effects of sea voyage on cellular immune function and nutrition status of naval servicemen. Methods A total of 173 male naval servicemen were included in the present study. The percentage of T, B and NK cell subpopulations from peripheral blood were assessed by flow cytometry. CD3+, CD3+CD4+, CD3+CD8+ and CD4+/CD8+ were employed as the markers of T cell subpopulation, CD3-CD19+ served as the marker of B cell subpopulation, and CD3-CD56+ served as the marker of NK cell subpopulation. The serum total protein (TP), albumin (ALB), glucose (Glu), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HLD-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A1 (ApoA1), apolipoprotein A2 (ApoA2), apolipoprotein B (ApoB), apolipoprotein C2 (ApoC2), apolipoprotein C3 (ApoC3), apolipoprotein E (ApoE), lipoprotein a (LPa), Fe2+, total iron-binding capacity (TIBC), Hb, K+, Na+, Cl-, Ca2+ and Mg2+ levels were determined by 7600DDP. Results Compared with that before sailing, the percentage of CD3+, CD3+CD4+ and CD4+/CD8+ elevated significantly during voyage (P

Objective To investigate the effects of swan shaped memory connector(SMC) on the bone mineral density and mechanical properties of humeral fracture in rabbits in order to disclose the mechanism of SMC stimulating fracture healing. Methods Shafts of both humeri of 40 rabbits were osteotomized. One side was selected to fix with SMC, but the contralateral side was fixed with the 4 hole dynamic compression plate (DCP). Eight rabbits were sacrificed and the humeri were harvested respectively at 2, 4, 8, 12 and 16 weeks after operation. The bone mineral density(BMD) was examined by dual energy radiographic absorptiometry(DRA). The mechanical properties were assessed by mechanical traction test. Results From 4 to 16 weeks after operation, the BMD in SMC group was significantly higher than that in DCP group ( P

Objective To observe the effect of kinesthetic imagery and visual imagery on upper limb rehabilitation among stroke survivors.Methods Forty-five hemiplegic stroke survivors were randomly assigned into a kinesthetic imagery training group (n=14),a visual imagery training group (n=15) or a control group (n=16).In addition to conventional rehabilitation,patients in the kinesthetic and visual imagery training groups were given 30 minutes of the appropriate imagery training once a day,five days per week for four weeks,while the control group relaxed or received health education for the same time.Before and after the 4-week intervention,the upper limb section of the Fugl-Meyer assessment (FMA-UE) and the modified Barthel index (MBI) were used to evaluate the motor function of the subjects' upper limb and their ability in the activities of daily living respectively.Results Before the intervention,there were no significant differences in the average FMA-UE and MBI scores among the 3 groups.After the intervention there was no significant difference between the average FMA-UE and MBI scores of the two training groups,but both were significantly better than the control group's averages.Conclusion Either kinesthetic or visual imagery training can improve the upper limb function of stroke survivors and their abihty in the activities of daily living.Their effectiveness is not significantly different.

Objective:
To evaluate efficacy of the BiRd regimen, a combination of clarithromycin, lenalidomide, and dexamethasone, in the treatment of patients with relapsed/refractory multiple myeloma (RRMM) .
Methods:
Patients with RRMM treated with BiRd between September 11, 2013 and August 1, 2016 at six centers were included to evaluate overall survival rate (ORR) , clinical benefit rate (CBR) , progression-free survival (PFS) , overall survival (OS) , as well as adverse events.
Results:
Of 30 patients with RRMM, 27 patients were evaluable, and ORR and CBR were 51.9% (14/27) and 66.7% (18/27) respectively, including 1 sCR (3.7%) , 3 CR (11.1%) , 3 VGPR (11.1%) , and 7 PR (25.6%) . In 13 patients with prior Rd, ORR and CBR were 38.5% (5/13) and 61.5% (8/13) respectively, of which 5 patients with ≥MR carried high-risk cytogenetic[ (e.g.17p- or t (4;14) ] together with at least one of other adverse-prognostic cytogenetic (e.g.13q- and/or 1q21+) . In 24 patients with prior bortezomib-based therapy, ORR and CBR were 45.8 and 62.5%, respectively. With a median follow-up time of 14.9 (range 1.0-33.8) months, the median PFS and OS were 12.0 (95%
