Objective This study is to examine the effect of different breathing patterns (abdominal respiration,natural respiration)on skin temperature(TEMP),skin conductivity(SC) and heart rate variability (HRV) in college students.Methods We use single blind trial in the study,and randomly select thirty students,including fourteen male and sixteen female,aged 19.6±0.77 years,and then randomly divide them into two groups:the intervention group (abdominal respiration group,6 males and 9 females) and the control group(natural respiration group,8 males and 7 females).In the study three phases are included:baseline phase(five minutes),test phase(fifteen minutes),recovery phase(five minutes).Data of above indicators was collected at 3-5 min,14.5-19.5 min,and 23-25 min,respectively,during the study.Results (1) There are no significant difierences of all three indicators between the two groups in the baseline phase(P<0.05).(2)The SC of the test phase in the intervention group is lower than in the control group (P=0.05),while the TEMP and HRV of the two groups show no significant differences(P>0.05).(3)There are no significant differences of TEMP and the HRV in the recovery phase between the two groups(P>0.05),except the SC (P<0.05).Conclusion No significant difference is observed between the influences of abdominal and natural respiration on the emotion-related biological indicators.

Objective To observe the dynamic changes of high-sensitive C-reactive protein (hs-CRP) and visfatin in patients with acute traumatic injury of brain. Method A total of 120 patients with equal number in each gender ( n = 60) and with average age of (43.2 ± 6.2) years were admitted and treated by the neurosurgical department of ICU from August 2009 to June 2010. All patients were eligible to the diagnostic criteria of craniocerebreal injury. The clinical conditions of patients were assessed with Glasgow coma scale (C CS) at admission,and as per the scores of GCS, the patients were classified into mild degree (13- 15, n = 40), moderate degree (9 - 12, n = 40) and severe degree (3 - 8, n = 40). Another 60 subjects from those asking for health care by physical examination as control with equal number in each gender and their average age was (42.2±6.7) years.Blood samples were collected from fasted patients within 12 hours, 1d, 3d, 7d and 15 days after admission, and the levels of hs-CRP and visfatin in peripheral blood were detected. Results The levels of hs-CRP and visfatin were significantly higher in brain injury group than those in control group on the admission day (both P ＜ 0.01 ),and they both had positive relationships with severity of injury. The level of hs-CRP increased to peak on the first day of admission and visfatin increased to the peak on the 3rd day after admission. There was a correlation between levels of hs-CRP and visfatin ( r = 0.63, P ＜ 0.01 ). Conclusions hs-CRP and visfatin levels are related to the severity of acute traumatic injury of brain.

Objective: To assay the content and stability of vitamin C(VC) in serum by a simple, specific method. Methods: Serum samples were extracted by metaphosphoric acid, and analyzed on a column C 18 of HPLC with DAD detector at 234 nm. Mobile phase was 100 mmol/L KH 2PO 4, pH3.00. The flow rate was 1 ml/min. Results: Under this condition, the retention time of VC was 5.76 min. The within run and between run reproducibilities tests were 0.42% and 2.11% respectively, and the recovery rate ranged from 82% to 88.5%. Stored at -70 ℃ and compared to that of its metaphosphoric acid extract, serum VC content was stable only for two days, and then decreased rapidly, whereas it did not decrease in metaphosphoric acid extract until the fifth day. Conclusion: A simple, sensitive and reliable method of HPLC with DAD detector is established for measuring VC in either serum or fruit, such as orange juice. VC should be determined immediately or should be extracted with metaphosphoric acid as soon as possible, then the extracts are kept at -70 ℃, and analysed within 5 d.

This study is purposed to investigate the effects of praeruptorin A (PA) and praeruptorin C (PC) on UGT1A1 in HepG2 cells through hCAR pathway. PA and PC were incubated with HepG2 cells for 24 h and 48 h, mRNA and protein expressions of UGT1A1 were determined by real-time PCR and Western blotting assays. Additionally, effects of PA and PC on UGT1A1 mRNA and protein expressions were also measured after transient transfection of a specific CAR siRNA for 72 h in HepG2 cells. UGT1A1 mRNA and protein expression levels were significantly increased by PA and PC after incubation for 48 h. Moreover, the mRNA and protein up-regulations of UGT1A1 were attenuated by transient transfection of a specific CAR siRNA, suggesting the induction was mediated by CAR. The results suggest that PA and PC can significantly up-regulate UGT1A1 expression partially via the CAR-mediated pathway.

Objective To establish gastric bypass surgery model with SD rat and analyze the influence factors and preventive measures so as to accumulate experience and skills for further developing gastric bypass surgery model on diabetic rat( GK rat) . Methods Gastric by-pass surgery was operated on 30 SD rats. Summarized modeling experience and analyzed various factors affecting modeling success. Results 17 rats weresuccessfully survived after surgery and 13 failed, with the mortality rate 43. 3%. Three rats died during operation, including two for anesthesia and one for heart failure;one died due to anastomotic bleeding two hours after surgery. Eight died in the third day after surgery, including two for infection, two for intestinal necrosis, four for anastomotic stenosis or obstruction. One died because of anastomotic leakage caused by mistaking and satiety the fifth day after surgery. There were no other complications such as wound dehiscence occurred in this group . Conclusion Establishing models of gastric bypass surgery with SD rats which is regarded as pre-experiment of building models of gas-tric bypass surgery with GK rats is economical and feasible. Anesthesia and perioperative management, surgical techniques and infection pre-vention and control are the main factors affecting modeling. The survival rate of rat model could be increased if related factors well controlled.
