Objective To evaluate the effect of combination transfer pump and single blood pump to 32 cases of renal failure patient who need blood purification therapy.Methods The combination transfer pump and single blood pump were used.According to the clinical requirement,the parameters of transfer pump were set such as therapy time,replacement liquid flow rate,dialysate flow rate,temperature of warmer and filtrate flow rate,etc.Results 32 patients with varying degrees of illness have been alleviated.Patients' acute left heart failure,water and electrolyte turbulences,acid intoxication and azotemia caused by liquid retention were corrected,which ensured a role for further treatment.Conclusion It is the functions of adjustable time and transfusion volume that are used in the combination transfer pump,the task of which is accomplished by several transfer pumps together.This method is easy to implement and can meet the clinical requirement largely without special CBP instrument.

Objective To investigate the effects of Thalidomide(THD)on transdifferentiation of human fetal lung fibroblast(HFL-F) to myofibroblast(MF) induced by Transforming Growth Factor-?1(TGF-?1) and the effects on trans differentiated MF.Methods HFL-F to MF trans-differentiation was induced with 5 ?g/L TGF-?1.The effect of 50 ?g/L THD on HFL-F to MF transdifferentiation was evaluated by measuring hydroxyproline(HYP) content with alkaline hydrolysis colorimetry,?-smooth muscle actin(?-SMA) protein with Western Blot,?-SMA and collagen Ⅲ(COL Ⅲ) mRNA with semiquantitative RT-PCR.Results THD inhibited TGF-?1 induced up-regulation of HYP and COLⅢ mRNA expressions(all P0.05).For HFL-F treated with 5 ?g/L TGF-?1 for 96 h,THD inhibited COLⅢ mRNA expression(P

Objective:To evaluate the effects of different types of resistance training on the treatment and prevention of sarcopenia in the elderly.Methods:A computer search was conducted in seven databases including PubMed, Embase, Web of Science, Cochrane Library, CNKI, VIP, and Wanfang, to identify randomized controlled trials published from the inception of the databases to March 2023, for the assessment of the preventive effects of resistance training on sarcopenia in older adults.Two reviewers independently performed the literature search, selection, and quality assessment of the included studies.A Meta-analysis was conducted using RevMan 5.3.Results:A total of 12 studies with 1018 participants were included.Compared with the control group, resistance training significantly improved the skeletal muscle mass index( MD=0.34, 95% CI: 0.24~0.44, P<0.01), grip strength( MD=1.63, 95% CI: 0.73~2.53, P<0.01), and 5 times sit-to-stand test performance( MD=-1.99, 95% CI: -2.48--1.51, P<0.01).However, there was no significant improvement observed in muscle mass( MD=1.28, 95% CI: -0.38-2.94, P>0.05), knee extensor strength( SMD=1.71, 95% CI: -0.51-3.93, P>0.05), or gait speed( MD=0.03, 95% CI: -0.03-0.08, P>0.05). Conclusions:Resistance training improves the skeletal muscle mass index, grip strength and the time taken to perform the 5 times sit-to-stand test in the elderly, thus delaying degenerative skeletal muscle changes in older adults with sarcopenia and offering a preventive effect on sarcopenia in healthy senior adults.
