ABSTRACT
Objective:To investigate the level of family support and health literacy in elderly patients with knee osteoarthritis, and to analyze the correlation.Methods:This study was a cross-sectional study. Totally 172 knee osteoarthritis patients were recruited by convenience sampling method from the department of Orthopaedics in Honghui Hospital, Xi ′an Jiaotong University from July to December, 2021. General data questionnaire,Chronic Disease Health Literacy Scale and Family Support Scale were used for questionnaire survey. Results:The total score of family support in elderly patients with knee osteoarthritis was (10.20 ± 2.61), and the total score of health literacy was (93.62 ± 12.68). The results of single factor analysis showed that family support and health literacy in elderly patients with knee osteoarthritis were affected by gender, education level, marital status, residence, family income per capita and other factors. The results of correlation analysis showed that family support was positively correlated with the level of health literacy ( r=0.730, P<0.05). Conclusions:The family support of elderly knee osteoarthritis patients is medium level, and health literacy needs to be strengthened. Therefore, when formulating the health management plan of patients′ health literacy and the related support of family support, targeted attention should be paid to the influencing factors and intervention measures should be implemented.
ABSTRACT
Objective To investigate characteristics of glucose metabolism of non-obese and obese women with polycystie ovary syndrome(PCOS).Methods From March 2008 to July 2011,118 PCOS patients were enrolled in this study and were divided into 53 cases (body mass index(BMI) ≥25 kg/m2) in obese group and 65 cases (BMI ＜ 25 kg/m2) in non-obese group.Participants' clinical data,glucose tolerance and insulin release test results were retrospectively reviewed.The prevalence of type 2 diabetes mellitus (T2DM),results of oral glucose tolerance test,impaired fasting glucose (IFG),impaired glucose tolerance (IGT) were compared between the two groups.Results (1) Blood glucose levels:at the time points of 30,60,120 and 180 minutes,the levels of fasting glucose were (5.2 ± 1.1),(8.5 ± 2.8),(8.1 ± 2.4),(6.3 ± 2.0) and (4.8 ± 1.5)mmol/L in non-obese group and(5.4 ±0.9),(9.1 ± 1.8),(9.3 ±0.6),(7.6 ± 1.0) and (5.4 ±0.8) mmol/L in obese group.Statistical difference was observed between obese and non-obese groups at each time point (t =-6.125,-4.005,-6.074,-6.751 and-4.512 respectively,P ＜0.01).(2) The level of insulin:at the time points of 30,60 and 120 min,the level of fasting insulin were (8 ± 4),(55 ± 21),(65 ± 14) and (45 ±18)mU/L in non-obese group and (13 ± 8),(85± 30),(105± 54) and (76 ± 46)mU/L in obese group.There were significant statistical difference between the two groups at each time point (t =-17.024,-12.540,-15.791 and-16.149 respectively,P ＜ 0.01).However,at the time point of 180 minutes,the level of insulin did not exhibit significant difference between obese and non-obese groups (P ＞ 0.05).(3) The prevalence of abnormal glucose metabolism:The rates of IGT were 13.85 ％ (9/65) in non-obese group and 24.53 ％ (13/53)in obese group,which also showed remarkable difference (x2 =18.446,P ＜ 0.01).The rates of T2DM were 1.54％ (1/65) in non-obese group and 7.55％ (4/53) in obese group,which reached significant difference (x2=16.005,P ＜ 0.01).Conclusion Abnormal glucose metabolism was observed more frequently in overweight or obese PCOS women.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the effect of the total flavonoids of Jiawei Wuzi Yanzong prescription on the Voltage-gated calcium channel of the CA1 pyramidal cell of rat hippocampus.</p><p><b>METHOD</b>The inward calcium current was recorded by the whole-cell patch clamp and the amplitude of it was thought to observe the effect of Abeta25-35 and the total flavonoids. The hippocampus of rat was separated and cut into slices. Active pyramidal cells of slices were chosen for the whole-cell patch clamp recording. After exposure to Abeta25-35, voltage steps (500 ms) were used to depolarize stepwise in a range from 50 to +50 mV (increment: 5 mV). An inward Ca2+ current which was suggested to be survey was evoked. Application of the total flavonoids was to be observed if it had effect on this voltage-depended inward current.</p><p><b>RESULT</b>Abeta25-35 could enhance the calcium current to induce intracellular calcium overload. The amplitude of the control group was--(157.1 +/- 19.9) pA, but after application of Abeta25-35 the current enhanced to--(323.2 +/- 23.4) pA. When the total flavonoids at concentration of 125, 250, 500 g x L(-1) were added, the current declined to--(257.9 +/- 31.6), - (196.4 +/- 29.8) and--(169.3 +/- 34.0) pA, respectively.</p><p><b>CONCLUSION</b>Abeta-induced intracellular calcium overload may be one of neurotoxic of beta-amyloid peptide. The total flavonoids of Jiawei Wuzi Yanzong prescription can suppress inward calcium current to protect neurons.</p>
