ABSTRACT
Objective:To explore the effect of exercise therapy on the exercise capacity and quality of life of maintenance hemodialysis patients.Methods:A total of 90 patients who underwent regular dialysis in Henan Provincial People′s Hospital, People′s Hospital of Zhengzhou University from April to December, 2020 were selected as the research objects by convienient sampling method. They were divided into experimental group and control group by random number table method, with 45 cases in each group. The control group was given routine nursing, and the experimental group took exercise therapy on the basis of routine nursing. The intervention lasted for 12 weeks. The changes in the exercise capacity and quality of life of the two groups before and after the intervention were observed.Results:Finally, 43 patients were included in the control group and 41 patients in the experimental group. There was no significant difference in the exercise capacity and quality of life before the intervention between the two groups( P>0.05). After the intervention, the maximum oxygen uptake, anaerobic threshold, 6MWT distance were (15.22 ± 3.08) ml·kg -1·min -1, (620.70 ± 53.56) ml·kg -1·min -1, (475.36 ± 50.51) m in the experimental group, and (12.22 ± 2.46) ml·kg -1·min -1, (590.18 ± 52.07) ml·kg -1·min -1, (444.50 ± 46.09) m in the control group, the differences were statistically significant between the two groups( t=3.32, 2.68, 296, all P<0.05). After the intervention, the scores of physiological function, physiological intelligence, physical pain, overall health, vitality, social function, emotional function and mental health dimensions of the quality of life were (84.32 ± 18.53), (84.61 ± 25.80), (76.40 ± 18.15), (59.02 ± 15.38), (52.22 ± 13.68), (69.56 ± 17.29), (94.24 ± 29.47), (73.44 ± 12.86) points in the experimental group, and (76.25 ± 17.35) (66.37 ± 27.63), (65.68 ± 17.54), (47.26 ± 15.45), (44.86 ± 13.14), (61.82 ± 16.51), (76.30 ± 26.14), (64.17 ± 13.36) points in the control group, the differences were statistically significant between the two groups( t values were 2.08-3.54, all P<0.05). Conclusions:Exercise therapy during dialysis can enhance exercise capacity and improve quality of life in maintenance hemodialysis patients.
ABSTRACT
OBJECTIVE@#To report on clinical characteristics and genetic findings in 15 Chinese patients with methylmalonic acidemia (MMA).@*METHODS@#For the 15 MMA patients detected by tandem mass spectrometry, genetic analysis was carried out in twelve pedigrees. Clinical characteristics, genetic finding, treatment and outcomes were retrospectively analyzed.@*RESULTS@#The main features of the patients included poor feeding, recurrent vomiting, lethargy, seizure and development retardation. Blood propionylcarnitine (except for 3 patients), its ratio with acetylcarnitine, and urine methylmalonic acid were increased in all patients. Twelve patients were diagnosed genetically, which included 7 with MUT variants, 4 with MMACHC variants, and 1 with MMAB variant. Nine MUT variants were detected, among which c.1159A>C, 753+1delGinsTGGTTATTA and c.504del were novel. Six known pathogenic MMACHC variants and two novel MMAB variants (c.289_290delGG, c.566G>A) were also detected. Seven patients died of metabolic crises within a year, others had improved effectively following the treatment, but had mild to severe growth delay and/or developmental retardation.@*CONCLUSION@#The clinical manifestation of MMA are complex. Most patients have variants of the MUT and MMACHC genes. High mortality may occur before one year of age.

ABSTRACT
Objective To establish chemiluminescent immunoassay(CLIA) for quantitative detection of Rabies virus antibody in human serum.Method The purified antigen was coated on the microplate,pairing with alkaline phosphatase(ALP)-labeled antigen and luminescence substrate CSPD,then the double antigen sandwich CLIA was established.Results The sensitivity of the assay was 0.2IU/ml.The linear range was from 0 IU/ml to 200 IU/ml.The precision was less than 10%.The analytical recovery rate was from 90% to 110%.Conclusion The CLIA is a simple,sensitive,special and repeatable method for detection of Rabies virus antibody.It was suitable for clinical application.
