Objective To observe the effects of low frequency electrostimulation(LFES)on sleep disorder of patients after acute cerebral infarction(ACI)as evaluated by using polysomnography,and on the recovery of neurological deficits. Methods Seventy cases of acute cerebral infarction were randomly divided into two groups,a treatment group and a control group.Both groups were treated with routine drugs, and the treatment group was also treated with LFES in addition.The changes of neurological deficits(ND) scores and such parameters of polysomnography as sleep latency(SL),total sleep time (TST),sleep efficiency(SE%),sleep maintenance(SMT),rapid eye movement sleep(REM),REM latency(RL),REM time(RT),REM activity(RA),REM density(RD).stage 1 sleep(S1),stage 2 sleep(S2)and deep sleep (S3+4) were observed.Results It was shown that,after treatment,both groups got significant improvement in terms of the ND scores and all the polysomnography parameters except RA,S1 and S2,(P<0.01),and the treatment group improved to a significantly greater extend when compared with the control group (P<0.01).Conclusion It is concluded that LFES could promote recovery of neural function and sleep disorder of ACI patients.

Objective To investigate the effect of pressure ulcers wound record form on the quality of nursing records in geriatric wards . Methods Twenty-eight patients with pressure ulcers hospitalized from January to June 2014 were assigned as control group , where the pressure ulcers assessment and nursing form was used for recording pressure ulcers . Another 30 patients during July to December 2014 were assigned as the trial group , where the pressure ulcers wound record form was used . The two groups were compared in terms of time for writing nursing records , satisfaction of nurses and problems in recording the pressure ulcers . Result Compared with the control group, the time for writing nursing records was much shorter, the satisfaction degree was significantly higher and the problems in recording wounds were significantly fewer as well. Conclusion The pressure ulcers wound record form can enhance the quality of pressure ulcers wound records, shorten the time for writing the records and increase the nurses′satisfaction.

Objective To explore the potential risk of misdiagnosis of pharyngeal esophageal diverticulum( PED) for the treatment of thyroid nodules with thermal ablation and its rapid and effective method of diagnosis . Methods The process of diagnosis and treatment were reviewed on 5 cases of PEDs which had been misdiagnosed as thyroid nodules and recommended for thermal ablation therapy . A comprehensive analysis was carried out for the reasons of misdiagnosis ,the timing and clues of the diagnosis as well as the advantage of swallow contrast-enhanced ultrasonography ( sCEUS ) in achieving rapid and correct diagnosis . Results The lack of recognition and vigilance to the acoustic image of PED were the direct causes of misdiagnosis . Five cases of PED misdiagnosed as thyroid nodules were all discovered by the same chief operator before thermal ablation . They were confirmed through sCEUS and mistreatment by ablation were fortunately avoided ,but all true thyroid nodules requiring treatment were safely ablated . Conclusions PED is easily misdiagnosed as thyroid nodule .Improving the recognition and vigilance of the ultrasonic features of PED ,strictly implementing the reconfirming ultrasound examination by the chief operator ,and promptly conducting sCEUS are sensible measures to quickly correct the diagnosis and prevent w rong ablation of PED .

Objective: To investigate the effect of 1q21 amplification (1q) on the therapeutic response and prognosis of bortezomib(Btz) in the treatment of newly diagnosed multiple myeloma (MM) patients. Methods: A total of 180 newly diagnosed MM were included for analyses of clinical characteristics, cytogenetics, objective response rate (ORR), progression-free survival (PFS) and overall survival (OS), retrospectively. Gene expression profiling (GEP) was analyzed using publicly available R2 platform. Results: ① In 180 patients, 1q was found in 51.1% cases. Of them, 174 patients had complete follow-up data, including 88 cases with 1q and 86 without 1q (non-1q). ②Incidence of 1q was positively associated with percentage of IGH rearrangement (72.2%, P=0.017) and 1p deletion (1p) (27.8%, P=0.040). ③ The median PFS was 15.0 and 20.3 months for the 1q group and non-1q group, and the median OS was 29.4 and 44.0 months, respectively. Both PFS and OS of 1q group was significantly shorter than those of the non-1q group (P=0.029 and 0.038, respectively). Multivariate analysis further revealed that 1q was an independent prognostic factor for both PFS (HR=1.910, 95% CI 1.105-3.303, P=0.020) and OS (HR=2.353, 95% CI 1.090-5.078, P=0.029). ④ In 91 evaluable cases with 1q, very good partial remission (VGPR) rate was higher after treatment with Btz than those without Btz (62.1% vs 40.0%, P=0.032). Of note, the patients with 1q who received auto-HSCT after induction with Btz had significantly longer PFS than those without auto-HSCT (19 months vs 13 months, P=0.048). ⑤GEP analysis revealed that 1q21 amplification predominantly up-regulated expression of >50% genes within 1q21 region, and also altered expression of 28% genes in chromosome 1 and 10% genes in whole genome, particularly related to DNA repair and cell cycle. Conclusions 1q is an independent adverse prognostic factor in patients with newly diagnosed MM. It is often associated with 1p deletion and IGH rearrangement. Patients with 1q respond well to Btz-based regimen, but they fail to gain long-term benefit from this treatment itself. However, auto-HSCT following Btz induction might improve survival of patients with 1q, suggesting a potential strategy to treat this high-risk subset of MM. GEP analysis warrants further attention in understanding the mechanisms underlying the high-risk of 1q.
