Objective To investigate the effect of electro-acupuncture (EA) on vascular permeability in patients undergoing open-heart surgery with CPB. Methods Thirty-two NYHA class Ⅰ or Ⅱ and ASA class Ⅱ or Ⅲ patients with BMI of 19-28 kg/m2 undergoing open heart surgery with CPB were randomly divided into 2 groups ( n = 16 each): Ⅰ control group and Ⅱ acupuncture group . The patients were premedicated with intramuscular phenobarbital 0.1 g, pethidine 50 mg and scopolamine 0.3 mg. Anesthesia was induced with midazolam, propofol, fentanyl and vecuronium and maintained with TCI of propofol and fentanyl in both groups. The patients were acupuncture points (neiguan, lieque, yunmen) were selected for stimulation with stimulator. Acupuncture stimulation was started from 30 min before anesthesia induction and continued until the end of operation. The level of sedation was monitored by BIS and maintained at 40-60 during operation. Urinary microalbumin concentration was used as a parameter of vascular permeability, and was measured before and at the end of operation. Blood samples were taken 24 h before and 24 h after operation for measurement of ALT, AST, total bilirubin, BUN and Cr. Results The two groups were comparable with respect to sex ratio, age, body weight, ASA physical status, and preoperative ejection fraction. There was no significant difference in renal and liver function between the 2 groups.Postoperative urinary microalbumin concentration was significantly lower in acupuncture group than in control group. Conclusion Acupuncture can reduce the effect of open heart surgery performed under CPB on vascular permeability.

Objective To observe the clinical effects of Bufei Yishen treatment on quality of life of patients with chronic obstructive pulmonary disease in stable period. Methods Sixty-four patients were randomly divided into two groups, the control group (32 cases) received Atrovent metered dose inhaling and Mucosolvan po. The treatment group (32 cases) received the fluid extract of Bufei Yishen besides the routine treatment. Both groups were treated for three months. The changes of scores of TCM syndrome and cardinal symptom, quality of life (QOL), lung function were observed before and after the treatment. Results The scores of TCM syndrome and cardinal symptom, quality of life of the treatment group were significantly higher than the control group (P0.05). Conclusion Bufei Yishen treatment has significantly effect on quality of life of patients with chronic obstructive pulmonary disease in stable period.

Objective The study consisted of two parts: in part Ⅰ the effects of propofol or/and procaine on CD18, CD62L expression and superoxide anion (SOA) release of phorbol 12-myristal 13-acetate(PMA) stimulated human neutrophils (PMNs) were studied in vitro; in part Ⅱ the effects of propofol or/and procaine on IL-6 and TNF-?production in endotoxin-stimulated human whole blood were studied. Methods PMNs were separated from the whole blood obtained from healthy 20-40yr old subjects. Part Ⅰ consisted of 9 groups: in group 1 (control) phosphate buffer solution was added to PMNs; in group 2 PMNs were stimulated by PMA 100mg?ml-1 ; in group 3-5 different concentrations of propofol (0.4, 4.0,40?g?ml-1) were added to PMA stimulated PMNs; in group 6-8 different concentrations of procaine (1.5,15,150?g?ml-1 ) were added to PMA stimulated PMNs; in group 9 propofol 2?g?ml-1 and procaine 8?g?ml-1 were added to PMA stimulated PMNs. Part II also consisted of 9 groups: in groupl whole blood was mixed with normal saline; in group2 lipopolysaccharide (LPS) l?g?ml-1 was added to whole blood; in group 3-5 different concentrations of propofol (0.4,4.0,40?g?ml-1) were added to LPS stimulated whole blood; in group 6-8 different concentrations of procaine (1.5, 15, 150?g?ml-1 ) were added to LPS stimulated whole blood; in group 9 propofol 2?g?ml-1 and procaine 8?g?ml-1 were added to LPS stimulated whole blood. CD18, CD62L expressions were measured by flow cytometry. SOA release was determined by cytochrome C reduction in the presence or absence of superoxide dismutase (SOD) . IL-6 and TNF-? production were measured by using radioimmunoassay. Results Propofol or/and procaine depressed CD18 up-regulation, CD62L shedding and SOA release of PMA-stimulated PMNs and propofol was more effective than procaine. Propofol enhanced but procaine inhibited the increased production of TNF-? and IL-6 in the LPS stimulated whole blood but when propofol and procaine were used in combination. The effectof procaine predominated. Conclusions Propofol or/and procaine can attenuate tissue damage induced by neutrophils by inhibiting the function of neutrophils.

Objective:To explore whether different phospholipid peptides could induce different pathological features of EAE in Lewis rats.Methods:Lewis rats were immunized with myelin basic protein 82-99 (MBP82-99),MBP68-86,and myelin oligodendroglia glycoprotein 35-55 (MOG35-55),respectively,and evaluated everyday for neurological scores.The cerebrum,brain stem,cerebellum and spinal cord of every rat were removed and pathological features observed.Results: Rats immunized with the two MBP peptides exhibited neurological signs of EAE wherein the central nervous system had extensive inflammation infiltration.The number of infiltrates in spinal cords in the two MBP peptides groups was higher than that in the cerebrums,brain stems and cerebellums.In spinal cords, there was no statistical difference of infiltrates between MBP82-99 and MBP68-86 groups;however,the both groups had more infiltrates than MOG35-55 group.Inflammatory cells were observed only in spinal cords of animals immunized with MOG35-55.Conclusion:This study provides certain evidence for understanding the diversity of pathological manifestations of EAE in Lewis rats.

Objective To investigate the effects of different degrees of hemodilution on neurological injury and amino acid content in different brain areas after deep hypothermic circulatory arrest (DHCA) . Methods Forty-eight male adult SD rats weighing 400-450 g were randomly divided into 4 groups ( n = 12 each); group 1 Hct 10% (H1); group II Hct 20% (H2); group III Hct 30% (H3) and control group (C). All animals except those in control group underwent DHCA at 18 ℃ for 90 min (including cooling and rewarming) under general anesthesia with fentanyl, ketamine and droperidol. Different degrees of hemodilution were accomplished by changing the composition and volume of priming solution used in cardiopulmonary bypass (CPB) . Hct was determined before, at the initiation of CPB and beginning of rewarming. PaO2, pH and blood lactate of arterial blood and SO2 of venous blood from internal jugular vein (SjvO2 ) were determined at the beginning and end of cooling and rewarming. The animals were killed and brains removed after recovery of circulatory function for the count of injured neurons and determination of glutamate (Glu), aspartate (Asp), glycine (Gly), ?-aminobutyric acid (GABA) and taurine (Tau) contents in cortex, hippocampus and thalamus. Results The number of injured neurons in hippocampus and parietal cortex was significantly smaller in Hct 30 % group than in the other two groups (P

Objective To detect the expressive levels of hepatocyte growth factor and D2-40 and its correlation with clinicopathological factors and microlymphatic density in gastric carcinoma. Methods Immunohistochemistry method was used to detect the expression of HGF and D2-40 in gastric cancer tissue, with microlymphatic density(MLD) counted. Results The expression of HGF had the positive correlation with histologic types, infiltration depth, clinical stage and lymph node metastasis (P <0.05). No correlation was found in age, tumor diameter(P >0.05). In gastric cancer, the MLD in the HGF-positive group (22.8±10.9) was higher than that in the HGF-negative group(14.0±4.2, P <0.05). Conclusion The expressive levels of HGF have the positive correlation with histologic types, infiltration depth, clinical stage, lymph node metastasis and MLD in gastric carcinoma. HGF can be used to predict prognosis of gastric carcinoma.

One hundred and fifty patients with 70 percent or more of carotid steno-ocelusion confirmed by digital subtraction angiography were selected to analyze risk factors for its clinical symptoms.Results of analysis showed that risk for clinical symptom increased with severity of unilateral carotid stenosis (OR = 3.546,95% CI 1.515-8.300,P = 0.004).Whereas presence of "functional complete circle of Willis" was a protective factor for it (OR = 0.208,95 % CI 0.045-0.962,P = 0.045).

Dengue is the most common vector borne viral disease of humans globally.Detection of viral RNA from suspected patient specimens is rapid,specific and confirmative in laboratory diagnosis of dengue infections during the acute phase.In this study,a multiplex nested reverse transcription PCR (RT-PCR) system was established for clinical specimens.While other nucleic acid amplification tests showed relatively low sensitivity,the multiplex nested RT PCR assay detected 4 cases among blood clots from 8 serologically confirmed dengue patients.These results suggested that blood clots of dengue patients could be used in laboratory diagnosis,and that the multiplex nested RT PCR assay,which simplified the detection procedure,could facilitate viral RNA detection of specimens in clinical laboratories.

Objective To explore whether patients with bipolar disorder are deficit in their theory of Mind (ToM) and the factors influencing the ToM.Methods Three groups (27 with bipolar disorder,27 with schizophrenia,and 26 in health control) were tested.All subjects' ToM was assessed by Faux pas Questions and IQ by WAISR.The symptoms of groups of patients were measured by Positive and Negative Symptom Scale (PANSS).Results Three groups' scores of Faux pas Questions(ToM scores) displayed significance(One-Way ANOVA:F(2,77) =13.686,P =0.000) ; Post-hoc test (Games-Howell) showed that ToM scores (13.81 ± 5.66) of bipolar disorder group were lower than those of the control group (17.04 ± 3.79) and higher than the schizophrenia group (9.44 ±6.13).The difference was significant (P =0.048,0.024).Independent sample t test showed that ToM scores of gender in bipolar disorder group were not significant (male:13.20 ± 6.07,femal:14.58 ± 5.26,t =-0.623,P =0.539).There was no correlation between ToM scores of patients with bipolar disorder and their age,years of education,age of onset,duration of illness,scores of negative,positive and general psychiatric rating scale of PANSS,and IQ (＞ 70).Linear regression by stepwise regression was used on each specific symptom of the PANSS,and according to the outcome,related factor was selected as independent variables,the ToM scores as the dependent variable.The regression equation was ToM scores =21.79-1.53 G12-3.16 N6 ;R2adjust was 0.46.Conclusion Patients with bipolar disorder as a whole compared to the control have deficit in their ToM,and the deficit is less than that of patients with schizophrenia.G12 and N6 of the PANSS are the influencing factors,which explain 46％of the variation sources.
