ABSTRACT
ObjectiveTo analyze the quality of life and related factors in patients with depression， and to provide evidence for formulating the corresponding measures to improve the patients' quality of life. MethodsA total of 117 inpatients who met the International Classification of Diseases， tenth edition（ICD-10） for depression were selected in Central People's Hospital of Zhanjiang， Affiliated Hospital of Guangdong Medical University and Guangdong 999 Brain Hospital from November 19， 2018 to September 7， 2019. The values of patients' clinical objective indicators consisted of routine blood test， routine urine examination， blood biochemical tests and blood gas analysis were collected by reviewing their medical records， and all subjects were assessed using Quality of Life Instruments for Chronic Diseases-Depression V2.0 ［QLICD-DE（V2.0）］. Simple correlation analysis was used to explore the correlation between the QLICD-DE （V2.0） scores and various clinical objective indicators， and multiple linear regression was adopted to further screen factors affecting quality of life of patients with depression. ResultsSimple correlation analysis suggested that QLICD-DE （V2.0） total score was positively correlated with total protein and platelet distribution width in patients with depression （r=0.198， 0.281， P<0.05 or 0.01）， and negatively correlated with hematocrit （r=-0.300， P<0.01）. Multiple linear regression analysis showed that albumin-to-globulin ratio and treatment compliance （B=-19.836， -3.711， P<0.05 or 0.01） were influential factors for physical function. Platelet distribution width （B=2.706， P<0.01） was an influential factor for psychological function. Bilirubin （B=-6.375， P<0.05） was an influential factor for social function. Platelet distribution width （B=2.101， P<0.05） was an influencing factor for specific module. The albumin-to-globulin ratio and platelet distribution width （B=-10.653， 2.114， P<0.05 or 0.01） were influencing factors for total score of QLICD-DE （V2.0）. ConclusionTreatment compliance and clinical objective indicators platelet distribution width， bilirubin and albumin-to-globulin ratio may be the influencing factors of quality of life in patients with depression.
ABSTRACT
BACKGROUND: Salvia miltiorrhiza is widely used to treat angina cordis, ischemic stroke and other ischemic cardiovascular diseases. However, the effects of Salvia miltiorrhiza on ovariectomized rats remain unclear.OBJECTIVE: To observe the effects of Salvia miltiorrhiza on the body mass, food intake, and levels of blood lipids and malondialdehyde (MDA) in ovariectomized rats.DESIGN: A completely randomized and controlled experiment.SETTING: Institute of Physiology and Psychology, School of Basic Medical Sciences, Lanzhou University.MATERIALS: The experiment was performed in the Key Laboratory of Pre-clinical Study for New Drugs of Gansu Province and the laboratory of Institute of Physiology and Psychology, School of Basic Medical Sciences, Lanzhou University from November 2005 to December 2006. Twenty-four healthy female SD rats of 3 months old and (220±2) g were selected. Salvia miltiorrhiza water decoction (equal to 1 g/mL crude drug) was identified and extracted by Drug Control Institute of Gansu Province; MDA kit was purchased from Nanjing Jiancheng Institute of Bioengineering.METHODS: ①The rats were randomly divided into three groups with 8 rats in each group: sham-operated group,ovariectomized group and Salvia miltiorrhiza group. The rats were underwent a bilateral ovariectomy except those in the sham-operated group, which were subjected to a removal of bilateral fat as much as ovariectomized group with the ovaries remained. Rats in sham-operated group and ovariectomized group freely drank water; rats in Salvia miltiorrhiza group freely took 1% water extracts from Salvia miltiorrhiza postoperatively, and the concentration of Salvia miltiorrhiza gradually increased to 12% on the eighth day, which was lasted until the end of the experiment (55 days). ②The food intake of rats in each group was monitored daily, and the body mass was measured every five days. At the end of the experiment, femoral artery blood samples of rats were collected to determine the levels of blood lipids. At the same time,MDA was measured according to the kit.MAIN OUTCOME MEASURES: The body mass, food intake, levels of blood lipids and malondialdehyde in each group.RESULTS: Twenty-four rats all entered the result analysis. ①The body mass of rats in 3 groups was nearly the same before operation (P ＞ 0.05). While the body mass in ovariectomized group on the postoperatively 10th, 20th, 25th, and 55th days was significantly higher than those in sham-operated group (P ＜ 0.01). The body mass in Salvia miltiorrhiza group on the postoperatively 20th, 25th, and 55th days was significantly lower than those in ovariectomized group (P ＜0.05-0.01). ②The food intake in ovariectomized group on the postoperatively 15th, 40th, and 55th days was significantly higher than those in sham-operated group (P ＜ 0.05-0.01), and that in Salvia miltiorrhiza group was significantly lower than those in ovariectomized group at those 3 time points (P ＜ 0.05-0.01). ③At the end of the experiment, the levels of total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol and triglyceride in ovariectomized group were significantly higher than those in sham-operated group (P ＜ 0.05-0.01). The levels of triglyceride and MDA in Salvia miltiorrhiza group were significantly lower than those in ovariectomized group (P＜0.01, 0.05).CONCLUSION: Salvia miltiorrhiza can significantly reduce the body mass and levels of triglyceride and MDA in ovariectomized rats.
ABSTRACT
BACKGROUND: Ephedra, a Chinese medicine, is often used to treat obesity with relatively satisfying results recently. However, the effects of Ephedra on the perimenopausal and postmenopausal obese women remain unclear.OBJECTIVE: To observe the effects of oral Ephedra decoction on body mass and the levels of blood lipids, blood glucose and hormone in ovarietomized obese rats.DESIGN: A completely randomized and controlled experiment.SETTING: Institute of Physiology and Psychology, School of Basic Medical Sciences, Lanzhou University.MATERIALS: The experiment was performed in the Key Laboratory of Pre-clinical Study for New Drugs of Gansu Province and the Laboratory of Institute of Physiology and Psychology, School of Basic Medical Sciences,Lanzhou University from February 2006 to June 2006. Forty-four healthy female SD rats were randomly divided into four groups with 11 rats in each group, namely sham-operated group, ovariectomized group, estrogen replacement therapy group and Ephedra group.METHODS: ① After having been narcotized by cloraminone (110 mg/kg),rats were underwent a bilateral ovariectomy except those in the sham-operated group, which were also operated, but their ovaries were not cut off. ②Rats in the sham-operated group and ovariectomized group were subcutaneously injected with sesame oil (0.2 mL/each rat) every day postoperatively till the end of the experiment. ③ The rats in the estrogen replacement therapy group were given estradiol (1 mg/kg) by subcutaneous injection every day postoperatively till the end of the experiment. ④ The rats in the Ephedra group freely drank 1% water extracts from Ephedra postoperatively, later the concentration of Ephedra gradually increased to 8% on the sixth day, which lasted until the end of the experiment. ⑤ The food intake was monitored daily, and body mass was measured every ten days. ⑥ At the end of the experiment, all the rats were fasted for 12 hours and collected blood samples for the measurement of serum indexes. The body mass and body length were measured to calculate the Lee's index [(g)×103/body length (cm)] at the same time.MAIN OUTCOME MEASURES: ① Body mass and Lee's index at different time points in each group. ② Food intake at different time points in each group. ③ Levels of blood lipids and blood glucose in each group. ④Levels of estrogen, progesterone and insulin in each group.RESULTS: Forty-four rats all entered the analysis of results. ① Result of body mass and Lee's index at different time points: The body masses on the 20th, 30th, 40th and 50th days in the ovariectomized group were (256.4±14.3),(271.3±16.1), (276.4±12.7), (285.7±24.2) g, which were significantly higher than those in the sham-operated group [(226.5±11.5), (241.8±12.6),(243.1±13.5), (251.1±22.4) g, P ＜ 0.05-0.01], and the Lee's index in the ovariectomized group was greater than that in the sham-operated group(317.2±13.5, 280.4±11.2, P ＜ 0.01). The body masses on the 40th and 50th days in the estrogen replacement therapy group were (243.7±14.8) and(246.2±11.9) g, which were significantly lower than those in the ovariectomized group (P ＜ 0.05-0.01), and the Lee's index (289.9±13.5) was lower than that in the ovariectomized group (P ＜ 0.01). The body masses on the 40th and 50th days in the Ephedra group were (245.4 ±14.1) and(252.4±14.9) g, and the Lee's index was 294.4±11.0, which were all lower than those in the ovariectomized group (P ＜ 0.05). ② Result of Food in take at different time points: The food intakes on the 30th, 40th and 50th days in the Ephedra group were (17.8±2.4), (22.3±3.9), (26.1±3.5) g per day,which were decreased as compared with those in the ovariectomized group[(25.9±4.7), (28.5±5.3), (32.8±5.5) g per day, P ＜ 0.05]. ③ Levels of blood lipids and blood glucose: The levels of triglyceride, cholesterol and low density lipoprotein cholesterol (LDL-C) in the ovariectomized group were (1.73±0.32), (1.45±0.50), (0.78±0.19) mmol/L, which were higher than those in the sham-operated group [(0.94±0.29), (1.05±0.30), (0.08±0.11) mmol/L, P ＜ 0.01]. After the estrogen replacement therapy, the levels of triglyceride, cholesterol, LDL-C and blood glucose were (1.10±0.34),(1.14±0.30), (0.17±0.05), (5.88±1.21) mmol/L, which were lower than those in the ovariectomized group (P ＜ 0.05-0.01), but the level of high density lipoprotein cholesterol (HDL-C) was higher than that in the ovariectomized group [(1.11±0.31), (0.88±0.21) mmol/L, P ＜ 0.05]. The levels of triglyceride, cholesterol, LDL-C and HDL-C in the Ephedra group were (0.97±0.16), (1.11±0.20), (0.59±0.07) and (0.45±0.061) mmol/L, which were lower than those in the ovariectomized group (P ＜ 0.05-0.01). ④ The serum levels of estrogen, progesterone and insulin in each group: The serum levels of estrogen and progesterone in the ovariectomized group were lower than those in the sham-operated group [(17.09±9.00), (28.51 ±7.99) μg/L;(58.69±12.11), (62.73±10.93) μg/L, P ＜ 0.01], the serum level of insulin was higher than that in the sham-operated group [(31.74±6.69),(23.75±6.66) mU/L, P ＜ 0.01]. The serum levels of estrogen in the estro gen replacement therapy and Ephedra group were (36.03±8.83) and (30.18±8.61) ng/L, which were higher than those in the ovariectomized group(P ＜ 0.05-0.01), the level of insulin were (21.34±4.57), (24.86±6.20) mU/L,which were lower than those in the ovariectomized group (P ＜ 0.05-0.01).The serum level of progesterone in the Ephedra group [(17.68±6.19) μg/L]was lower than that in the ovariectomized group (P ＜ 0.01).CONCLUSION: Ephedra can promote loss of body mass, reduce levels of the blood lipids and insulin, and increase the serum levels of hormones in ovariectomized obese rats.
