ABSTRACT
Objective To examine the relationship between physical activity and glycemic control among type 2 diabetic patients with a good compliance level in China. Methods A total of 1 272 patients diagnosed with type 2 diabetes with a good compliance level were recruited from five community health centers in Nanjing Chemical Industry Administrative Zone from 2014 to 2016. Logistic regression models were used to examine the relationship between physical activity and glycemic control. Results In this cross-sectional study, 1 272 type 2 diabetic patients (596 men and 676 women) were recruited. The participants’ mean (standard deviation, SD) age was (64.63±9.04) years old. Male participants who achieved sufficient physical activity had the odds ratio (OR) of 2.11 (95%CI:1.17-3.18, P=0.013) for a tight glycemic control compared to their counterparts who had sufficient physical activity, after controling for the potential confounders, no significant association between physical activity and glycemic control status existed in women. Conclusions Physical activity is positively associated with glycemic control among male type 2 diabetic patients who had a good compliance level in Nanjing. Specific physical activity interventions should be implemented to type 2 diabetic patients
ABSTRACT
Aim To observe the expression of mesen-cephalic astrocyte-derived neurotrophic factor(MANF) in synovial membrane and serum of rats with adjuvant arthritis (AA) and to analyse the relationship between MANF expression and arthritis. Methods AA models were prepared by injecting Freund complete adjuvant (FCA) into SD rats. The swelling of the secondary joint was measured by foot volume measurement. The severity of AA was recorded by arthritis index (AI). Synovial pathological changes were observed by HE staining. The protein and mRNA levels of MANF,BiP and CHOP extracted from synovial tissues in different periods of AA rats were detected by Western blot and reverse transcription-polymerase chain reaction (RT-PCR), respectively. The levels of MANF, C-reactive protein (CRP), interleukin-1β (IL-1β) and tumor necrosis factor α (TNF-α) in serum were detected by enzyme-linked immunosorbent assay (ELISA) and then the relationship between MANF level and inflam-matory factors were explored. Results AA rat model was established successfully. The expression of BiP significantly increased in synovial tissue on d 2 after CFA injection,and decreased until d 28. The expres-sion of MANF slightly increased on d 2,then remained stable,and significantly increased on d 14, and then decreased gradually. The expression of CHOP kept to rise slowly at a low level. The level of MANF in serum markedly increased on d 14,then gradually decreased, but it was still higher than the normal level on d 28. The level of CRP exhibited similar trend with MANF. Correlation analysis showed that MANF had a negative correlation with arthritis symptoms, IL-1β and TNF-α in the secondary inflammatory period of AA rats. Con-clusions Arthritis induces the expression and secre-tion of MANF,and the level of MANF is closely relat-ed to the progression and severity of arthritis.
