Objective To investigate the effects of propofol on death-associated protein kinase (DAPK) mRNA expression in a rat model of traumatic brain injury (TBI). MethodsSixty male Wistar rats with a mean age of 3-4 months and mean body weight of 250-300 g were randomly divided into 6 groups ( n = 10 each) : Ⅰ normal control;Ⅱ sham operation; Ⅲ TBI; Ⅳ normal saline (NS) +TBI;Ⅴ fat emulsinn+ TBI and Ⅵ propefol + TBI. TBI was produced according to Feeney et al. In group Ⅲ-Ⅵ the animals were killed and their brains were removed at 24 h after brain contusion. NS 2 ml·kg-1 · h-1 , 10% fat emulsion 2 ml · kg-1 · h-1 and propofol 2 ml·kg-1·h-1 were infused iv for 4 h after lead trauma in group Ⅳ, Ⅴ and Ⅵ respectively. DAPK mRNA expression in the brain tissue was determined by RT-PCR and neuronal apeptosis was assessed by TUNEL. Results The expression of DAPK mRNA and neuronal apoptosis were significantly increased in the TBI group as compared with normal control and sham operation groups. Propefol infusion significantly attenuated neuronal apoptosis and reduced DAPK mRNA expression as compared with TBI, NS and FE groups. ConclusionPropofol can protect the brain from traumatic injury by suppression of the expression of DAPK mRNA.

To investigatethe relationship between p38 MAPK pathway and multidrug resistance of stomach cancer. The activity of p38 MAP kinase in stomach cancer cell SGC7901 and multidrug resistant cell SGC7901/VCR were examined by immunoprecipition after adriamycin treatment SGC7901 for 0, 2, 15, 30 and SGC7901/VCR for 0, 2, 15, 30, 60 minutes,respectively. The results indicated that adriamycin could activate the activity of p38 MAP kinase in gastric cancer cell SGC7901 with time dependency, but could decrease remarkably the activity of p38 MAP kinase in gastric cancer multidrug resistant cell SGC7901/VCR after adriamycin treatment it for 15 minutes. It suggested that adriamycin could affect the activity of p38 MAPK in gastric cancer cell SGC7901 and multidrug resistant cell SGC7901/VCR.

OBJECTIVE: The present study was to construct Der p 2 eukaryotic expression vector and validate its expression in the mouse bone marrow-derived dendritic cells. DESIGN, TIME AND SETTING: A single sample observation was performed at the Institute of Respiratory Disease,Xinqiao Hospital, Third Military Medical University of Chinese PLA between May and December 2005. MATERIALS: C57BL/6 mice were included. Plambd-Der p 2 was the product of Heska Company, USA.pCI-neo plasmid was provided by the Institute of Respiratory Disease, Xinqiao Hospital, Third Military Medical University of Chinese PLA.METHODS: Mouse bone marrow-derived dendritic cells were in vitro isolated and cultured.Complete Der p 2 cDNA was spliced from prokaryotic expression vector plambd-Der p 2, and then cloned into eukaryotic expression vector pCI-neo (pCI-neo-Der p 2).The positive recombinants pCl-neo-Der p 2 transfected into dendritic cells.Non-transfected and blank vector pCI-neo-transfected dendritic cells were used as controls. MAIN OUTCOME MEASURES: ①Identification of pCI-neo-Der p 2 recombinant plasmid.②Detection of Der p 2 mRNA and protein expression by reverse transcription-polymerase chain reaction (RT-PCR) and Western Blot techniques. RESULTS: Sequencing results showed Der p 2 cDNA in pCI-neo-Der p 2 was in coincidence with the sequence registrated in Gene Bank.RT-PCR and Western Blot results showed that expression of Der p 2 mRNA and protein could be detectable in the pCI-neo-Der p 2-transfected dendritic cells. CONCLUSION: The Der p 2 cDNA was successfully constructed into the eukaryotic expression vector, and Der p 2 gene and protein could be expressed efficiently in dendritic cells.

Objective To analyze CD+4 CDHi25 CDLo127 regulatory T cells (Treg) in peripheral blood of patients with thyroid nodules and differentiated thyroid cancer and their change regularity, and to investigate the immunosuppression mechanism. Methods The peripheral blood was collected from 175 patients with thyroid nodules, including 43 patients with differentiated thyroid cancer and 132 patients with nodular goiter.By using monoclonal antibodies, the blood samples were evaluated with the flow cytomertry for lymphocyte subsets and Treg cells. Results The results showed the prevalence of the CD+4 CDHi25 CDLo127 Treg in differentiated thyroid cancer group [(6.48±1.49) %] and nodular goiter group [(6.23+1.67) %] was higher than those in the healthy group [(5.62±1.48) %], and the difference was significant(P < 0.005), but there was no significant difference between the nodular goiter group and differentiated thyroid cancer group (P >0.005).Conclusion It is concluded that the relative increase of CD+4 CDHi25 CDLo127 Treg in peripheral blood of patients with nodular goiter and differentiated thyroid cancer may be related to immunosuppression and tumor progression.

Objective To understand how about the female consumers know the skin conditions of themselves and which they concern by a comprehensive questionnaire. Methods Three hundred and twenty-eight healthy volunteers in Shanghai were involved in this study. They were divided into 5 age groups equally. The questionnaire included the skin conditions, i.e. skin moisture, sebum, whiteness, redness, xanthochromia, homogeneity, spots, fine line, wrinkle, elasticity, angiotelectasis,pore, sagging, smoothness, gloss, roughness, scales and sensitivity. Each condition was divided into 10 grades to assess the skin conditions of the face (exposed site), upper arm (non-exposed site) and the perfect skin status. SPSS11.5 software was used to analyze the correlations of the skin conditions with ages. Results The skin concerns were difference in the 5 groups. Skin aging of sagging, wrinkle, spots and fine line became prominent from group C (35 to 40 years old). The correlations between the skin concerns of facial moisture, sebum, whiteness, homogeneity, spots, wrinkle, fine line, elasticity, sagging, sensitivity, upper arm sebum, spots, elasticity, angiotelectasis, sagging and roughness with ages were very significant (P＜0.01). Conclusion The changes of the volunteers'concerns about sebum, pore, sagging, elasticity, fine line and wrinkle with age in different age group are consistent with the quantitative measurement results from the oversea studies.

Objective To explore effects of sequel recanalization PCI therapy(primary coronary intervention,PCI) on cardiac function for the patients with acute ST segment elevation myocardial infarction(STEMI),and related factors.Methods 116 patients with STEMI enrolled were divided randomly into two groups:sequel recanalization PCI group(58 cases) and conventional PCI group(58 cases),and the patients of sequel recanalization PCI group were fully absorbed for thrombus before conventional PCI,then compared estoration of their cardiac function of the patients of two groups at once and 2 weeks after PCI procedure,respectively.Meantime to study the effect related-factors for cardiac function by Logistic regression analysis.Results There were significant differences between two groups in RESVmax(P =0.03) 、RESVmin(P = 0.00) 、REFmax(P = 0.00)、 REDVmax(P = 0.01) and the ratio of E/A(P =0.02)(all P＜0.05);it showed that the restoration of cardiac function of sequel recanalization PCI group was faster than that of conventional PCI group.If sequel recanalization PCI served as a variable for predicting REFmax being 50%,the results of logistic regression showed that OR(odds ratio) value was 3.47,95% CI(confidence interval) 1.39-9.75,P =0.04.Among other variables,as was time-to-recanalization(OR =4.59,P =0.01);infarct size(OR =4.59,P=0.01);Kiliip grades(OR = 3.99,P =0.02)and age(OR=2.75,P=0.04).Conclusion The sequel recanalization PCI could be better than conventional PCI for the patients with STEMI in restoration of heart function,but there should be some other effective factors.

Objective To explore the clinical significance of early invasive mechanical ventilation for acute respiratory distress syndrome (ARDS) caused by thoracic trauma.Methods We retrospectively analyzed the clinical data of 93 patients of invasive mechanical ventilation in those with ARDS caused by thoracic trauma,and divided them into delayed invasive mechanical ventilation group (n =45) and timely invasive ventilation group (n =48) by the time of invasive mechanical ventilation.We compared the blood gas analysis,oxygen index,heart rate,lactic acid,muscle use score of the two groups before and after invasive mechanical ventilation and the differences of mechanical ventilation time,incidence of complications,mortality and length of hospital stay between the two groups.Results Each index of the delayed invasive mechanical ventilation group and the timely invasive ventilation group was calculated:PaO2 (63.2 ± 12.3,74.2 ± 12.1)mm Hg,PaCO2 (39.4 ±8.7,38.9 +7.6) mm Hg,PaO2/FiO2 (196.2 ± 17.8,231.4 ± 18.2),respiratory rate (27.4 ±3.7,21.1 ± 3.4) beats/min,heart rate (117.2 ± 26.8,96.0 ± 25.1) beats/min,accessory muscle use score (2.69 ± 0.15,1.67 ± 0.10),lactic acid (4.23 ± 1.70,2.12 ± 0.80) mmol/L Except for PaCO2,the differences of each index were statistically significant (t values were respectively 4.346,9.420,3.949,5.436,38.809,7.736; P ＜ 0.05).The duration of mechanical ventilation treatment (10.21 ± 1.50,6.47 ± 1.20) d and the length of hospital stay (21.53 ± 1.90,16.32 ±2.10) d of the delayed group and the timely group were significantly different (t values were respectively 12.518,13.318; P ＜ 0.01).The timely group had significantly lower mortality rate (26.7％ (12/45),14.6％ (7/48)),VAP (46.7％ (21/45),22.9％(11/48)),acute gastric mucosal lesions (33.3％ (15/45),12.5％ (6/48)),MODS (40.0％ (18/45),16.7％ (8/48)) than the delayed group (x2 values were respectively 3.86,5.81,4.49,5.70; P ＜ 0.05).There is no significant difference on the incidence of pneumothorax between the two groups (11.1％ (5/45),8.3％ (4/48)).Conclusion Invasive mechanical ventilation is an effective treatment of ARDS caused by chest trauma.Early invasive mechanical ventilation can reduce the mortality rate and shorten the duration of mechanical ventilation and hospital stay of the patients with ARDS after severe thoracic trauma.
