OBJECTIVE:To establish the method for simultaneous determination of 5 heavy metals in Vespae Nidus,and to dis-cuss the effects of difterent producing area and part on the contents of heavy metals in Vespae Nidus. METHODS: The contents of arsenic(As),mercury(Hg),lead(Pb),cadmium(Cd)and copper(Cu)were determined by atomic spectrophotometry(hydride generation method,cold vapor method,graphite furnace method and flame method). The difference in the contents of heavy metals in samples were compared among different producing areas by analyzing data. RESULTS:The linear range of As,Hg,Pb,Cu, Cd were 0-40 ng/mL(r=0.9930),0-0.9 ng/mL(r=0.9974),0-80 ng/mL(r=0.9955),0-8 ng/mL(r=0.9927),0-800 ng/mL(r=0.9966),respectively. Limit of quantitation were 4.473,2.35×10 - 3 ,8.380,2.128,54 ng/mL,limit of detection were 1.342,0.701× 10 - 3,2.514,0.632,16 ng/mL. RSDs of precision,stability and reproducibility tests were all lower than 5.0%. The recoveries were 84.26% -102.25%(RSD=7.71% ,n=6),90.90% -115.31%(RSD=9.38% ,n=6),92.16% -105.70%(RSD=6.19% ,n=6), 90.81%-113.99%(RSD=8.86%,n=6),91.63%-102.79%(RSD=5.09%,n=6). The phenomenon that heavy metals of sample from Shandong and Hebei exceed the standard was the most serious. Main heavy metal which exceed the standard was Pb. The con-tent of Pb in Chamber was higher than other parts. CONCLUSIONS: The method is simple,precise,stable and reproducible,and can be used for simultaneous determination of 5 heavy metals in Vespae Nidus. There are different contents of heavy metal in Ves-pae Nidus of different producing areas and parts.

Objective To explore the role of combined respiratory function combined with drug therapy in the rapid recovery of lung cancer patients, and to provide reference for clinical treatment. Methods Forty patients with early non-small cell lung cancer (NSCLC) who underwent surgical treatment from January 2012 to December 2015 were selected as subjects and were randomly divided into intervention group and control group (n=20) according to the order of admission. All patients were treated with routine chemotherapy on the basis of routine chemotherapy of lung cancer, and routine perioperative care was carried out. The intervention group received comprehensive respiratory function exercise on the basis of them. There were psychological nursing, health education, perioperative respiratory function exercise and so on. The incidence of postoperative pulmonary complications, quality of life improvement and postoperative rehabilitation were compared between the two groups. Results The incidence of pulmonary complications in the intervention group was 5％ (1/20, only one case of pneumonia), the incidence of pulmonary complications in the control group was 35％ (7/20, 4 cases of pneumonia, two cases of atelectasis, one case of hypoxemia),the incidence of postoperative pulmonary complications in the intervention group was significantly lower than that in the control group (P<0.05). The scores of SF-36 in the intervention group were higher than those in the control group, the difference was statistically significant (P<0.05). The extubation time and postoperative hospital stay in the intervention group were shorter than in the control group. The 6-minute walking test (6MWK) was longer than the control group, the difference was statistically significant (P<0.05).Conclusion Comprehensive respiratory function combined with treatment with etestin hydrochloride can reduce the early postoperative pulmonary complications in patients with early non-small cell lung cancer, improve its quality of life and promote rapid postoperative rehabilitation.

Objective To study and analyze the effect of psychological intervention combined with glucocorticoid on the treatment of nephrotic syndrome and the quality of life in patients with nephrotic syndrome. Methods 100 patients with nephrotic syndrome treated in he affiliated hospital of Hangzhou normal university from February 2015 to August 2016 were selected and randomly divided into the control group and the experimental group, with 50 patients in each group. Patients in the control group received basic treatment, including trial and treatment, and diuretics, and were treated with corticosteroids on this basis. Patients in the experimental group on the basis of the control group, psychological intervention combined with glucocorticoid treatment, pay attention to the psychological status of patients and patients, strengthen communication and exchanges, increase confidence in the treatment and the treatment compliance of patients. The quality of life and treatment effect of the experimental group and the control group were compared and analyzed. Results After the corresponding treatment, the daily score of the patients in the experimental group was (15.19±3.19) points, and the daily life score of the control group was (22.21±5.19) points (QOL). The QOL score of the experimental group was significantly lower than that of the control group, and the quality of life was significantly higher than that of the control group, with statistical difference (P<0.05). The effective rate of the experimental group (90.0％) was significantly higher than that of the control group (66.0％), with statistical difference (P<0.05). Conclusion Psychological intervention combined with glucocorticoid on the treatment of nephrotic syndrome, the clinical effect is better, which can greatly improve the quality of life, and is worthy of promotion.

Objective:The aim of this study was to examine whether PSA levels were affected by BMI and the influence of BMI on the clinical application of PSA.Methods:A total of 856 males who had routine health checkups between January 2006 and July 2007 in our hospital were recruited for this study.Those with a documented history of prostate carcinoma were excluded.Height,weight, and total PSA were measured.The BMl was calculated from measured height and weight [BMl=weight(kg)/height(m)2].Results:The serum PSA(ng/mL)levels were 2.97±0.15 in the normal weight group,2.53±0.12 in the overweight group,and 2.01±0.16 in the obese group(P＜0.05).A negative correlation was found between PSA and BMI(r=-0.130,P＜0.05)and weight(r=-0.142.P＜0.05).A positive correlation was found between PSA and age(r=0.306,P＜0.05).Con-clusion:BMl is associated with PSA.As BMI increases, serum PSA decreases.The current data suggest that such an influence should be considered in the clinical application of PSA.
