Objective To evaluate the effect of hyperoxygenated solution on myocardial injury in the rats with acute carbon monoxide (CO) poisoning.Methods Thirty pathogen-free adult male SpragueDawley rats,weighing 250-300 g,were randomly divided into 5 groups (n=6 each) using a random number table:control group (C group),acute CO poisoning group (ACP group),and different doses of hyperoxygenated solution groups (HP1-3 groups).CO 120 ml/kg was injected intraperitoneally to establish the model of acute CO poisoning.Hyperoxygenated solution 10,15 and 20 ml/kg were infused via the caudal vein at 1 h after intraperitoneal injection of CO in HP1-3 groups,respectively.At 24 h after intraperitoneal injection of CO,blood samples were collected from the caudal vein for determination of plasma creatine kinase (CK),creatine kinase-MB (CK-MB),lactic dehydrogenase (LDH) and alpha-hydroxybutyrate acid dehydrogenase (α-HBDH) activities using the automatic biochemical analyzer.The rats were then sacrificed,and myocardial specimens were obtained for examination of the pathological changes with a light microscope.Results Compared with group C,the plasma LDH,α-HBDH,CK and CK-MB activities were significantly increased in ACP and HP1-3 groups (P＜0.01).Compared with group ACP,the plasma LDH,α-HBDH,CK and CK-MB activities were significantly decreased in HP1-3 groups (P＜0.05 or 0.01).Compared with group HP1,the plasma LDH,α-HBDH,CK and CK-MB activities were significantly decreased in HP2,3 groups (P＜0.05).The pathological changes of myocardium were significantly attenuated in HP1-3 groups as compared with group ACP.Conclusion Hyperoxygenated solution can attenuate myocardial injury in the rats with acute CO poisoning.

Objective:To explore the effect of music relaxation training combined with Huangqi Jianzhong Decoction oral administration and foot bath on fatigue status and quality of life in patients with cancer related fatigue.Methods:A total of 90 patients with cancer related fatigue in our hospital from January 2019 to October 2020 were selected. The patients were divided into 2 groups by random number table method, with 45 in each group. Both groups were given health and diet education. The control group was given music relaxation training, and the observation group took Huangqi Jianzhong Decoction oral administration and foot bathing on the basis of the control group. Both groups have a course of treatment of 4 weeks, a total of 3 courses. The TCM syndrome scores were observed before and after treatment, and the Piper Fatigue Score (PFS) was used to evaluate fatigue status, and the Karnofsky functional state score was used to evaluate the quality of life of patients, evaluation of clinical efficacy.Results:After treatment, 43 patients in the observation group and 42 patients in the control group were analyzed. The total effective rate of the observation group was 83.72% (36/43), which was significantly higher than 64.29% (27/42) of the control group ( χ2=4.18, P=0.041). After treatment, the TCM syndrome scores in the observation group was significantly lower than that of the control group ( t=2.48, P=0.015). After treatment, the Karnofsky functional state score in the observation group was significantly higher than that of the control group ( t=2.83, P=0.006). After treatment, the emotion score (4.35±1.02 vs. 5.03±1.01, t=3.09), feeling score (4.31±1.06 vs. 5.00±1.02, t=3.06) and total score (4.23±1.07 vs. 4.87±1.10, t=2.72) in the observation group were significantly lower than those in the control group ( P<0.01). Conclusion:Music relaxation training combined with Huangqi Jianzhong Decoction oral administration and foot bathing can alleviate the fatigue state of CRF patients and improve the quality of life.

Objective To investigate the gestational weight gain and quality of life in women with gestational diabetes mellitus(GDM) who used Free-Style Libre Flash Glucose Monitoring System. Methods From August of 2017 to January of 2019, the GDM patients diagnosed in the Department of Endocrinology in 3 ClassⅢ Grade A hospitals in Guangzhou were selected and divided into the observation group(n=39) and control group(n=43) according to their glucose monitoring willingness. The Free-Style Libre Flash Glucose Monitoring System was used for the observation group(sensor changed every 14 days) combined with the fingertip blood glucose monitor, it was necessary to monitor fingertip blood glucose contrast when hypoglycemia was identified by sensors. Pregnant women at other monitoring points could selectively monitor fasting and postprandial blood glucose. In the control group, after assigned into the group patients only monitored their fingertip blood glucose(at lease 2 times/d, including fasting and 2h postprandial blood glucose). The two groups were all instructed by self-management on diet, exercise etc according to the result of blood glucose monitor, the Wechat management was included to instruct them of the daily life diary recording method. World Health Organization-5 Well-Being Index (WHO-5) was adopted at the beginning of the study and the second week of follow-up to investigate the well-being index score of the patients in the two groups; at the end of pregnancy, the average perinatal blood sugar level, incidence of hypoglycemia events and the eligible rate of weight gain in different BMI patients were recorded. Results At the 2nd week, the score of well-being index in the observation group was higher than that in the control group with statistical significance(P=0.037).There was no statistically significant difference in fasting and 2 h postprandial glucose between the two groups (P＞0.05). There was no significant difference in blood sugar control (fasting and 2 hours after meal) between the two groups (P＞0.05), but the detection rate of hypoglycemia in the group using Free-style Libre glucose monitoring system was higher than that in the control group (P=0.042). By the end of pregnancy, stratified analysis showed that the qualified rate of weight gain in the observation group with BMI between 18.5 and 24.9 kg/m2 before pregnancy was higher than that in the control group with statistical significance(P=0.035). Conclusions The use of Free- Style Libre Flash Glucose Monitoring System in GDM patients makes gestational weight control more reasonable and painless, and improves the well-being index of patients.
