ABSTRACT
Objective To assess the effects of cognitive-behavioral group psychotherapy on depression,anxiety and medication adherence in elderly patients with coronary heart disease.Methods Eighty patients from two communities in Qinghai province were randomly divided into intervention group (n=40) and control group (n=40).In addition to regular care for both groups,patients in the intervention group also received eognitive-behavioral group psychotherapy.Depression,anxiety and medication adherence were measured with the Zung Self-Rating Depression Scale (SDS),the Zung Self-Rating Anxiety Scale (SAS) and the eight-item Morisky Medication Adherence Scale (MMAS-8),respectively,at baseline,immediately after intervention,at 3 months after intervention,and at 6 months after intervention.Results The repeated-measures ANOVA showed that improvement in depression,anxiety and medication adherence before and after intervention in the intervention group was greater than in the control group (F =22.805,48.058,128.058,all P＜0.05).Scores for depression and anxiety were lower and scores for medication adherence were higher (all P＜0.05) in the intervention group than in the control group at all the time points after intervention.Conclusions Cognitive-behavioral group psychotherapy can alleviate depression and anxiety,and improve medication adherence in elderly patients with coronary heart disease.
ABSTRACT
Objectives To explore the efficacy of CaNa2EDTA in the treatment of chronic moderate lead poisoning, so as to optimize the chelation therapy for lead poisoning in children. Methods The clinical data of 14 patients with chronic moderate lead poisoning treated with CaNa2EDTA for 3 consecutive courses of lead removal during September 2014 to December 2016 were analyzed retrospectively. Twenty-four hour urinary lead levels during hospitalization were analyzed. The changes of blood lead levels before treatment, 3 days, and 5 days after treatment were also analyzed. Results In the 14 children (4 males and 10 females) average age was 2.35±1.47 years. After treatment with CaNa2EDTA for 3 consecutive courses, the blood lead levels were decreased significantly in all the patients, and the blood lead levels at 3 days after treatment were 0.76, 0.77, 0.72 times those at 5 days after treatment respectively. The decrease of blood lead levels per unit of drug in the first 3 days of treatment were significantly higher than those in 5 days of treatment (P<0.05). The decrease of blood lead levels at 3 days after treatment was 0.65, 0.71, 0.70 times , those in 5 days' treatment respectively. The decrease of urine lead levels per unit of drug in the first 3 days of treatment were significantly higher than those in 5 days of treatment (P<0.05). Conclusions CaNa2EDTA has an obvious effect on removal of lead.The efficiency of lead removal in 3 days of treatment was higher than in 5 days of treatment. Thus, a course of treatment for 3 days may be an altenative for a course of 5 days.
ABSTRACT
OBJECTIVE:To study the hypoglycemic effects of Insulin self-microemulsion for parenteral administration on mod-el rats with type 1 diabetes in vivo. METHODS:Rats were treated with streptozotocin(50 mg/kg)to reproduce model with type 1 diabetes,ip. The model rats were randomly divided into model group (normal saline),positive control group (Insulin injection 2.25 u/kg) and self-microemulsion low,medium and high dose groups (Insulin self-microemulsion 4.5,9 and 18 u/kg);and 10 normal rats were involved in sham-operation group (normal saline). Anesthesia and operation were conducted for all rats. Positive control group was administrated,ip;other rats were parenterally administrated. The blood glucose levels in groups were detected be-fore and after 15-600 min administration. Glucose tolerance test was conducted for the rats in normal control group,model group without glucose,model group with glucose and microemulsion group (Insulin self-microemulsion 9 u/kg). All group were given glucose except model group without glucose. RESULTS:Compared with sham-operation group,the blood glucose levels in model group within 0-240 min were increased,with significant difference(P<0.05). Compared with model group,there was hypoglyce-mic trend in positive control group after 15 min,the blood glucose levels within 30-480 min were decreased,the hypoglycemic peak was 36%,and the peak time was 30 min;there was also hypoglycemic trend in microemulsion low,medium and high dose groups after 30 min,the blood glucose levels within 45-360 min were decreased,hypoglycemic peak was 18%-21%,and the peak time was 90-120 min,with significant differences (P<0.01 or P<0.05). All rats had glucose absorption peak except for model group without glucose in glucose tolerance test,and glucose of rats in microemulsion group reached its peak and then quickly de-creased. CONCLUSIONS:Insulin self-microemulsion can obviously reduce the blood glucose of model rats with type 1 diabetes.
