Objective To study the relationships among health-related quality of life(HRQL), social support, excessive daytime sleepiness (EDS) and PSG parameters in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS).Methods Eighty-five patients were recruited who were diagnosed as OSAHS by overnight po]ysomnography from August 2007 through November 2007 in West China Hospital.The Calgary sleep apnea quality of life index (SAQLI) was used for HRQL, social support rating scale (SSRS) was used for social support,and Epworth sleepiness scale(ESS) was used for EDS.The Pearson linear correlation and stepwise multiple regression analysis were used to analyze the correlation among SAQLI, SSRS, ESS, and PSG.Results The SAQLI was correlated with SSRS score (r = 0.402, P < 0.01) ; ESS score (r =-0.505 ,P <0.01) ; apnea-hypopnea index (AHI) (r =-0.269,P <0.05) and lowest artery oxygen saturation (ISaO2) (r = 0.226, P < 0.05).Stepwise muhiple regression analysis determined two variables,the SSRS and ESS score,as independent factors for predicting the total score of SAQLI which accounted for 37.3% of the total variance in the total score on SAQLI (R2 = 0.373, P < 0.001).Conclusions The HRQL of patients with OSAHS was correlated with the SSRS score, ESS score and PSG parameters.The former two were the more important factors to affect the HRQL of patients with OSAHS.

Objective:To evaluate the nutritional status before and after chemotherapy in patients with colon cancer by measuring energy metabolism and body composition.Methods:Fifty-one patients with colon cancer were included and were investigated using self-control method (before and after chemotherapy).Resting energy expenditure (REE) was determined by bed metabolic instrument,and body composition was measured by body composition analyzer.Results:For all patients,the REE on the 2nd day after chemotherapy was decreased significantly compared with that before chemotherapy (P ＜ 0.05).After chemotherapy,body fat percentage and body moisture percentage were increased significantly (P ＜ 0.05),and lean body mass percentage was decreased significantly (P ＜ 0.05).Conclusion:After chemotherapy,the REE and lean body mass percentage of the patients with colon cancer were decreased,and body fat percentage and body moisture percentage were increased.

Objective To investigate the effects of δ-opioid receptor agonist DADLE (D-Ala2-D-Leu5-enkephalin) on the hemodynamics and oxygen metabolism in rats with sepsis. Methods Eighty healthy male SD rats were randomly divided into 4 groups ( n = 20 each) : sham operation group (group S), sepsis group (group SEP) ,DADLE, group and DADLE2, group. Sepsis was induced by cecum ligation and puncture (CLP) in SEP, DADLE,and DADLE2 groups. In DADLE1 and DADLE2 groups, 0.5 mg/ml DADLE 10 mg/kg was injected intraperitoneally (IP) 0.5 h before CLP and immediately after CLP respectively. Mean arterial pressure (MAP), left ventricular systolic pressure (LVSP) and ± dp/dtmax were recorded at 0, 2, 4 and 6 h after CLP (T1-4). Blood samples from left common carotid artery and right external jugular vein were collected at T4 for blood gas analysis. The cardiac index (CI), O2 delivery (DO2), O2 consumption (VO2) and O2 extraction rate (ERO2) were calculated.Results Compared with group S, MAP and LVSP were significantly increased at T2, while decreased at T3,4, and ± dp/dtmax was significantly increased in group SEP, MAP was significantly increased at T2, while decreased at T3,4, LVSP was significantly increased at T2,3, while decreased at T4 , and ± dp/dtmax was significantly increased in DADLE, and DADLE2 groups, and CI, DO2 and VO2 were significantly decreased and ERO2 was increased in SEP, DADLE, and DADLE2 groups (P＜0.05). Compared with group SEP, MAP, LVSP and ± dp/dtmax at T3,4 and CI, DO2 and VO2 were significantly increased, while ERO2 was significantly decreased in DADLE1 and DADLE2 groups (P ＜ 0.05). There was no significant difference in the parameters mentioned above between DADLE1 and DADLE2 groups ( P ＞ 0.05). Conclusion δ-opioid receptor agonist DADLE can obviously improve the hemodynamics and oxygen metabolism in septic rats.

Objective To investigate the effect of δ-opioid receptor agonist D-Ala2-D-Leu5-enkephalin (DADLE) on the celluar immune function in septic rats. Methods One hundred and fifty healthy male SD rats weighing 154-198 g were randomly divided into 3 groups (n = 50 each):group Ⅰ sham operation (group S);group Ⅱ sepsis (group SEP) and group Ⅲ DADLE. Sepsis was induced by cecum ligation and punture (CLP) in group Ⅱ and Ⅲ. In group Ⅲ 0.5 rmg/kg DADLE 10 ml/kg was injected intraperitoneally (IP) immediately after CLP operation. Seven day survival rate was calculated. Blood samples were collected from 10 animals at 4, 8 and 12 h after operation (T1-3) respectively in each group for determination of serum TNF-α and IL-10 concentrations by ELISA and changes in T-cell subsets by flow cytometry. Results CLP significantly increased serum TNF-α and IL-10 concentrations and TNF-α/IL-10 ratio at T1-3 and decreased CD4+ and CD4+/CD8+ ratio and increased CD8+ at T3 in group Ⅱ as compared with group S (group Ⅰ). DADLE treatment significantly attenuated the CLP-induced above changes. Seven-day survival rate was significantly higher in DADLE group than in CLP group.Conclusion δ-opioid receptor agonist DADLE can improve the celluar immune function of rats with sepsis and increase the survival rate.

Objective To observe the effect of Shenqi Fuzheng injection combined with chemotherapy on reducing the side effects of malignant tumor chemotherapy. Methods Eighty cancer patients in Traditional Chinese Medicine Hospital of PLA General Hospital from January 2015 to March 2017 were randomly divided into treatment group and control group by using random number table method, each group contained 40 cases. The patients in the treatment group were given Shenqi Fuzheng injection combined with chemotherapy, while the control group used chemotherapy only. Results The incidence of WBC and Plt reduction in the treatment group [35.0 % (14/40), 32.5 % (13/40)] was lower than those in the control group [70.0 % (28/40), 57.5 % (23/40)], and the differences were statistically significant (χ 2= 9.825, P = 0.002;χ2=5.051, P=0.025). The incidence rates of digestive tract reaction and oral ulcers[52.5 %(21/40), 32.5 % (13/40)]were lower than those in the control group[75.0 %(30/40), 60.0 %(24/40)], and the differences were statistically significant (χ2= 4.381, P = 0.036; χ2= 6.084, P = 0.014). The quality of life in the treatment group was significantly improved compared with the control group [(51.4 ±5.1) points vs. (48.3±5.5) points], and the difference was statistically significant(t =2.595,P =0.011). Conclusions Shenqi Fuzheng injection combined with chemotherapy can reduce chemotherapy-induced side effects and improve the life quality of the patients.The injection can be used as the adjuvant therapy for chemotherapy in clinic application.

Objective:To detect serum levels of vitamin A (Vit A), vitamin D(Vit D)25-hydroxy vitamin D[25-(OH)D] and vitamin E(Vit E) in children aged 0-6 years in Tibetan Plateau of Garzi Prefecture, thus providing references for physical examinations and prevention of 4 key diseases (rickets, malnutrition anemia, pneumonia and diarrhea) in children in plateau areas by relevant government departments.Methods:A total of 2 122 children who participated in physical examination in 12 townships of Xiangcheng County and 14 townships of Daocheng County, Garzi Tibetan Autonomous Prefecture, Sichuan Province from April 2017 to April 2019 with 0-6 years old were recruited for surveying physical measurements and collection of venous blood.Serum Vit A and Vit E levels were detected by high performance liquid chromatography.Serum levels of 25-(OH)D were detected by high performance liquid chromatography tandem mass spectrometry.The relationship between Vit A, Vit E and 25-(OH)D levels with the gender, age, seasonal change and altitude was analyzed.Results:The serum Vit A level, subclinical Vit A deficiency rate and marginal vitamin A deficiency rate were(1.05±0.27) μmol/L, 8.15%(173/2 122 cases) and 45.99%(976/2 122 cases), respectively in 2 122 children with 0-6 years old.There were significant differences in the serum Vit A level, the subclinical Vit A deficiency rate and the marginal vitamin A deficiency rate in children with different ages, seasons and altitudes (all P<0.05). The serum level of 25-(OH)D and 25-(OH)D deficiency rate insufficient rate were (24.65±6.45) ng/L, 6.03%(128/2 122 cases) and 16.59%(352/2 122 cases), respectively.There were significant differences in the serum level of 25-(OH)D, 25-(OH)D deficiency rate and 25-(OH)D insufficient rate in children with different ages and seasons (all P<0.05). The mean serum Vit E level, Vit E deficiency rate and Vit E insufficient rate were (7.81±1.74) mg/L, 2.78%(59/2 122 cases) and 29.59%(628/2 122 cases), respectively.There were significant differences in serum Vit E level, Vit E deficiency rate and Vit E insufficient rate in children with different ages and seasons (all P<0.05). The mean serum levels of Vit A and Vit D remained the lowest before the age of 1 year, and their deficiencies at this age were the most significant.The mean serum level of Vit E remained the lowest in >1-2 years old, and its deficiency and insufficient at this age were the most significant.Vit A, D and E levels were significantly affected by seasonal changes, which were significantly higher in the summer than in the spring, autumn and winter.In addition, Vit A and 25-(OH)D were significantly affected by the altitude, which were the lowest above 4 km altitude. Conclusions:The overall serum levels of Vit A, 25-(OH) D and E in children with 0-6 years old in Tibetan Plateau areas of Ganzi Prefecture are lower than those in plain areas.Vit A, 25-(OH) D and Vit E levels significantly differed in the age, season and altitude, which are related to the lack of local resources, insufficient maternal nutrition during pregnancy and insufficient intake after birth, as well as temperature and light caused by changes in local seasons and altitude.Therefore, it is necessary to make reasonable supplements during pregnancy to prevent vitamin deficiency.
