The expression of C-myc, K-ras and H-ras oncoproteins in lymphocytesand monocytes, and NK subsets were studied in 21 patients with Behcet's syndrome (BS)and 40 healthy individuals. CD16~+,57~- cells of NK from BS patients were much decreasedwhen compared to the control. The positive percentages of three kinds of oncoprotein in BS lymphocytes and C-myc and K-ras oncoproteins in BS monocytes were significantly higher thanthat of the control. Positive correlations were found not only between C-myc expression oflymphocytes and serum ?-globulin%, IgM and IgG levels in BS, but also between C-mycexpression of monocytes and ESR. Expression of K-and H-ras oncoproteins in lympho-cytes and monocytes from BS patients were found to be negatively correlated with serumIgA level. Negative correlation was also found between C-myc expression in monocytesand CD16~+,57~- subset of NK. The significance of these results and the possible correlationsbetween BS and autoimmunity were discussed. It was suggeted that autoimmunity mightbe an important mechanism underlying BS.

AIM:To investigate the kinetics of tumor necrosis factor alpha(TNF-?)in an animal model of chronic P.aeruginosa biomembrane associated with lung infection.METHODS:Rats were challenged with 0.1 mL of PAO579(1012 CFU/L)in alginate beads or 0.1 mL of planktonic PAO579(1012 CFU/L).After challenging for 3,7 and 14 d,bacteriological and pathological features,and TNF-? expression in lung tissue were observed.RESULTS:(1)CFU/lung in alginate beads group was significantly higher than that in planktonic bacteria group(P

Objective To study the changes of insulin-like growth factor-1(IGF-1) in serum of patients with obstructive jaundice.Methods The clinical data of 20 patients with obstructive jaundice were collected and the measurement of serum TNF-?,ALT, ALP, endotoxin and IGF-1 were performed. Results The serum IGF-1 in obstructive jaundice was significantly lower than that in gallbladder stone(P

Objective To analyze the causes of recurrent hemoptysis after interventional treatment and to provide the reference to improve the interventional radiology technique in dealing with the hemoptysis.Methods From Oct.2000 to Oct.2008,repeated interventional procedure was carried out in 22 patients with recurrent hemoptysis after initial interventional treatment.After the bronchial arterial angiography and collateral branch arterial angiography were performed,embolization of diseased arteries with gelatin sponge particle,PVA particle or microcoil was conducted.Results Of 22 patients,re-canalization of the bronchial arteries was seen in 4,blood supply from additional bronchial artery other than from the already embolized bronchial artery in 3,and blood supply from the collaterals in 15.Technical success of the second interventional treatment was achieved in all the 22 cases.Bleeding ceased immediately after the second interventional treatment and no recurrent hemoptysis occurred during the follow-up period of 3 months to 4 years.Conclusion Complete embolization of all arteries related to the hemoptysis together with actively dealing with the primary disease can effectively improve the successful rate of interventional treatment for the massive hemoptysis.

Objective:To explore the formula and preparation technology parameters of Shengmai dispersible tablets. Methods:With the granulation status, disintegration time, friability, taste and and so on as the testing indices, the formula and preparation tech-nology of Shengmai dispersion tablets were optimized by uniform design. Results:The optimized formula of Shengmai dispersible tab-lets was as follows:25% extract powder, 58% MCC, 8% CCMC-Na, 4% CMS-Na, 2% L-HPC, 2% magnesium stearate and 1%sweetener. L-HPC and magnesium stearate were added after the granulation, and the tablet hardness was controlled at 25N. The opti-mized dispersible tablets could disintegrate uniformly within 3 min. Conclusion: The optimization of the prescription and preparation process parameters of Shengmai dispersing tablets is stable and reliable, and has good repeatability, and the process is feasible.

OBJECTIVE:To optimize enzymatic extraction technology of polysaccharide from Schisandra chinensis. METH-ODS:Using pH value of enzymatic extraction solution,the amount of enzyme,extraction temperature as response factor,S. chi-nensis polysaccharide as response value,on the basis of single-factor experiments,3-factor,5-level central composite experimental design was adopted for the experiment. Validation test was also conducted. RESULTS:The optimal extraction technology was as pH value of 5.7,enzyme dosage of 1.3%,extraction temperature of 53 ℃. In validation test,the extraction rate of S. chinensis polysaccharide was 14.30%(RSD=1.84%,n=6). CONCLUSIONS:The optimized extraction technology is simple,reasonable and stable,and can be used for the extraction of polysaccharide from S. chinensis.

Objective To investigate the effects of different durations of methamphetamine abuse on spatial cognitive processing.Methods The mental rotation task was used to evaluate the spatial processing function of 35 methamphetamine abusers and 30 healthy subjects.The methamphetamine abusers are divided into 2 groups according to their abuse durations,group 1 contains 16 abusers with an average duration of 1 year and group 2 contains 19 abusers with an average duration of 3 years.Participants were asked to judge the right hand/food or the left hand/food of the experimental stimuli at difference angles.The reaction time (RT) and the accurate rate (AR) of the mental rotation task were recorded.Results Compared with the control group,RT of group 1 methamphetamine abusers was longer at the angle of 0°((1469±318)ms) and 180°((1718±412)ms) (P＜0.05),RT of group 2 was longer at the angle of 0°((1466±243) ms),60°((1497±294) ms) and 180°((1708±288) ms) (P ＜0.05).And the AR of methamphetamine abusers was higher at every angle (P＜0.05).Conclusion Long-term dependence on methamphetmine can damage the abuser's spatial processing function.

Objective To explore the efficacy and safety of bedside continuous blood purification (CBP) in the treatment of critically ill neonates.Methods Totally ten critically ill neonates were hospitalized in Department of Neonatal Intensive Care Unit (NICU) in Shanghai Children's Hospital from June 2011 to May 2015, and managed with CBP treatment.The indications of CBP therapy were multiple organ dysfunction syndrome (MODS) failed to conventional treatment or combined with acute renal failure (ARF).The model for CBP was continuous veno-venous hemofiltration dialysis (CVVH).The clinical outcomes included blood electrolytes, serum bio markers, urine output, hemodynamic indicators, dose of intravenous epinephrine before treatment, 6, 12, 24, 48 h after treatment and at the end of CBP.Complications of CBP were also observed.Statistical analysis was performed with ANOVA and Dunnett-t test.Results The underlying problems of the ten newborns were septicemia (n=5), severe neonatal asphyxia (n=2), congenital hereditary metabolic disease (n=2) and traumatic asphyxia (n=l).The venous catheter was successfully inserted for all babies and CBP treatment continued for (86.7 ± 25.9) h averagely with obvious effect.Four of the ten cases were cured and discharged, and the rest six refused to treatment and died after due to irreversible injury of the nervous system although they had survived from the oliguric stage of ARF.The complications of CBP included thrombocytopenia (n=3), catheter blockage (n=2), hypotension (n=l).No hypothermia, thrombosis, bleeding or infection occurred.The mean blood pressure and partial pressure of oxygen in arterial blood/fraction of inspiration oxygen (PaO2/ FiO2) of the ten cases 6 h after the beginning of treatment were higher than those before [(46.4 ± 7.5) vs (36.5 ±8.3) mmHg, 1 mmHg=0.133 kPa;(210.0±62.0) vs (93.0±43.0) mmHg;t=2.647 and 6.378, both P ＜ 0.05].At the 12th hour since treatment start, the blood pH value was 7.4 ± 0.2, which was higher than that before treatment (6.9 ± 0.2, t=2.731, P ＜ 0.05), and kept in normal range.At the 24th hour, the serum levels of potassium, urea nitrogen and creatinine dropped to normal range compared to those before treatment [(4.8±2.9) vs (9.6± 3.6) mmol/L;(7.2±2.3) vs (13.6±6.3) mmol/L;(51.0± 12.0) vs (172.0±23.0) μ mol/L;t=4.571, 5.427 and 21.672, all P ＜ 0.05].Urine output increased from zero before the treatment to (0.7±0.3) ml/(kg · h) after 24 h (t=3.284, P ＜ 0.05).The maintaining dose of intravenous epinephrine decreased since 12 h after the beginning of treatment and was ceased at the 48th hour.Conclusion CBP is an effective and feasible treatment for critically ill neonates.
