[Poor Oral Health and Sarcopenia in the Elderly:a Review of Their Correlation and Intervention Measures].

Sarcopenia is a common geriatric syndrome associated with the occurrence of adverse consequences such as falls,debility,and death,seriously affectingthe quality of life of the elderly.Oral health as the basis of the overall health plays a vital role in improving the overall quality of life and extending the healthy life span of the elderly.Studies have demonstrated that poor oral health may increase the risk of sarcopenia.By reviewing the recent studies about oral health and sarcopenia in the elderly,we summarize the related mechanisms and put forward some intervention measures,so as to provide a theoretical basis for the prevention and treatment of sarcopenia from the aspect of oral health.

[Mechanism of Impaired Cognitive Function in Patients with Chronic Kidney Disease].

Each stage of chronic kidney disease has a high risk of cognitive dysfunction.The decline of cognitive function will affect the daily life and treatment compliance of the patients with chronic kidney disease and increase the patients' risk of death and public health burden,which has aroused widespread concern.However,the specific mechanism of cognitive impairment in the patients with chronic kidney disease remains unclear.This paper summarizes the possible association mechanisms,related indicators,and impaired cognitive domains,aiming to provide a theoretical basis for the early diagnosis and slow down the progression of the cognitive impairment associated with chronic kidney disease.

Establishment of complete blood count reference intervals for Chinese preschoolers.

BACKGROUND: Reference intervals are critical for interpreting test results of a clinical laboratory. The aim of this study was to establish local reference intervals of complete blood count for healthy preschoolers in China. METHODS: Three thousand eight hundred and twenty-one blood specimens from children aged 4 months to 6 years were collected and analyzed. Complete blood counts were determined by Sysmex XT-4000i Automated Hematology Analyzer. The nonparametric 2.5th to 97.5th percentile reference ranges were calculated according to CLSI EP28-A3c guideline. RESULTS: Reference intervals for each blood cell parameter are determinded as follows: total WBC 4.86-12.1×109 /L for males and 4.73-12.3×109 /L for females; RBC 4.13-5.32×1012 /L for males and 4.08-5.24×1012 /L for females; HGB 109-145 g/L for males and 111-143 g/L for females; HCT 33.1-41.2% for males and 33.3-41.1% for females; MCH 23.5-29.7 pg for males and 24.6-30.0 pg for females; MCHC 320-365 g/L for males and 321-362 g/L for females; MCV 71.4-85.1 fL for males and 73.8-86.9 fL for females; RDW-SD 33.5-41.9 fL for males and 33.5-41.0 fL for females; RDW-CV 12.0-15.2% for males and 11.8-14.5% for females; PLT 181-475×109 /L for males and 179-456×109 /L for females; PCT 0.18-0.44% for males and 0.18-0.43% for females; MPV 8.20-11.6 fL for males and 8.20-11.5 fL for females; PDW 8.40-14.4 fL for males and 8.40-14.0 fL for females; P-LCR 12.0-36.6% for males and 11.8-35.6% for females. CONCLUSIONS: We established local complete blood count reference intervals for apparent healthy preschoolers in China. It is necessary to establishing region-specific reference intervals of complete blood count for preschoolers.
