Objective To explore the illness experience and perspectives of youth patients with systemic lupus erythematosus (SLE) in China. Methods The research was conducted following phenomenological approach of qualitative research. Twelve patients with SLE were selected through purposive sampling method.The interviewer conducted hour-long semi-structured interviews according to the proposed interview outline.Data were analyzed based on Colaizzi phenomenological research method. Results Three themes were identified, including emotional experience since illness, SLE related limitations, and perceived stigma. Conclusions There exists a dynamic variation in disease related experience of young SLE patients.Understanding the feelings of those patients can help eliminate the negative factors so as to provide effective nursing intervention for patients and improve the quality of young patients′life with long-term living.

This experiment aims to investigate the effects of a dietary supplement of herbal tea resi-due on white feather broilers in the prospectives of growth performance,serum indexes and intesti-nal immune indexes.A total of 280 1-day-old white feather broilers with similar body mass and good health were randomly divided into 4 groups with 5 replicates per group and 14 birds per repli-cate.Group Ⅰ(control group)was fed a basal diet.Groups Ⅱ,Ⅲ and Ⅳ were fed a diet supple-mented with 2%,4%and 6%herbal tea residue powder,respectively.The feeding lasted for 49 days,and was divided into 2 phases from 1 to 21 days of age and 22 to 49 days of age.Blood,tissue and mucosa of the duodenum and jejunum were collected on 21 d and 49 d.Total cholesterol(T-CHO),triglyceride(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C)and the activities of aspartate aminotransferase(AST)and alanine amin-otransferase(ALT)in the serum were examined.The villus height and crypt depth of the jejunum were observed and measured by morphology.The mRNA expression levels of intestinal interleukin-1β(IL-1β),interleukin-2(IL-2),interleukin-4(IL-4),interleukin-10(IL-10)and tumor necrosis factor-α(TNF-α)were determined by qPCR.The results showed that compared with group Ⅰ,the mass of group Ⅲ on 21 d and 49 d significantly increased(P<0.05).The average daily feed intake of 22-49 d and 1-49 d significantly increased(P<0.05).The average daily mass gain of 1-21 d,22-49 d and 1-49 d significantly increased(P<0.05).In the serum of 21 d,compared with group Ⅰ,T-CHO in group Ⅱ significantly decreased(P<0.05).TG in groups Ⅱ,m and Ⅳ significantly de-creased(P<0.05).LDL-C and AST activity in group Ⅳ significantly decreased(P<0.05).In the serum of 49 d,T-CHO in group Ⅲ,LDL-C in group Ⅳ,HDL-C of groups Ⅲ and Ⅳ significantly increased(P<0.05),and the ALT activity of these two groups decreased(P<0.05).AST activity in group Ⅱ significantly decreased(P<0.05).In the duodenum of 21 d,compared with group Ⅰ,the expressions of TNF-α in group Ⅱ was significantly decreased(P<0.05).In the duodenum of 49 d,the expression of IL-10 in group Ⅱ was significantly increased(P<0.05),and the expression of IL-2 in groups Ⅲ and Ⅳ was significantly decreased(P<0.05).In the jejunum of 49 d,the ex-pression of IL-10 in group Ⅱ was increased(P<0.05),and the expression of IL-2 in groups Ⅲand Ⅳ was significantly decreased(P<0.05).In conclusion,dietary herbal tea residue can regulate circulating lipid level and enhance intestinal immunity of white feather broilers without affecting their normal growth performance.This experiment also suggested that the a 2%-4%supplementa-tion of herbal tea residues to white feather broilers was of good effect.

The study adopted muscle injection of pVAX1-SP-GHRH(1-44)expression plasmid and electrostimulation to determine its effects on mouse growth and sow production performance.One hundred and fifty four-week-old C57 BL/6 female mice were randomly divided into 6 groups of 5 replicates each.Muscle single-injection followed by electrostimulation was performed.The con-trol group received an empty plasmid injection(80 μg/kg),while the treatment groups received pVAX1-SP-GHRH(1-44)plasmid injections(20,40,80,120,160 μg/kg).Twenty healthy preg-nant sows were randomly divided into 2 groups,each with 10 sows.Electrostimulation treatment was applied to the semimembranosus muscle of the pregnant sows after a single injection.The con-trol group received physiological saline injection,while the plasmid group received a 2 mg pVAX1-SP-GHRH(1-44)expression plasmid injection.Mouse weight,feed intake,and serum GHRH and IGF-1 levels were measured at days 0,7,14,21,and 28 after injection.Pregnant sows were bled via the tail vein at days 0,14,28,and 42 after injection,and their serum was separated to measure serum GHRH and IGF-1 levels.The birth weight,placental weight,number of piglets born,number of healthy piglets,number of weak piglets,number of deformed piglets,number of stillborn piglets,and number of mummified piglets were recorded at day 14.The mouse study re-sults showed that muscle injection of pVAX1-SP-GHRH(1-44)plasmid followed by electrostim-ulation could promote mouse feeding and increase weight gain(P<0.05),significantly increase mouse serum GHRH and IGF-1 levels(P<0.05),and maintain its effects until day 21.The results of the pregnant sow study showed that the average birth weight of the piglets in the plasmid group was significantly increased(P<0.01),and the placenta weight was significantly increased(P<0.05).The serum GHRH and IGF-1 concentrations in the plasmid group sows were significantly increased(P<0.01).The study results showed that muscle injection of pVAX1-SP-GHRH(1-44)expression plasmid followed by electrostimulation could promote mouse feeding and increase weight gain,and also significantly improve the average birth weight and placental weight of the piglets in pregnant sows.
