ObjectiveTo study the correlation between blast lung injury (BLI) and acute posttraumatic stress disorder(PTSD) through the establishment of the model about blasting injury of rats.Methods84 SD male rats were randomly divided into four groups:the normal control group( A),the model groups ( B,C) and the sham model group(D).21 rats in each group.The chest of the model group and sham model group rats,respectively,were exposed to 8＃ instantaneous electric detonator at different distances.Then,emotion and behavior of rats was observed through open field test and elevated plus maze test,at day 1,14,28 after blasting.Group A was not given the explosion of stress treatment.After testing,each group was randomly picked up seven rats for succumbing to draw blood which was used to detecting the level of plasma corticosterone by radioimmunoassay,respectively.Results( 1 ) On day 1,it was a significant difference that the latency time ( LT),crossing frequency (CF),rearing frequency(RF) and modification frequency(MF) which were both group B( (25.34 ± 4.50)s,( 19.73 ± 11.10 ),(0.52±0.11),(0.53±0.21) respectively)and group C((22.13 ±6.54)s,(28.67 ±7.22),(1.07 ±0.26),( 0.89 ± 0.15 ) respectively ) were compared with group A,including LT,CF and RF of group D ( ( 23.71 ± 3.9 ) s,(25.13 ± 12.35 ),( 1.26 ± 0.74 ) respectively ) (P ＜ 0.05 ).Then,on day 28,although there was a significant difference which both the LT,CF and RF of group B,and the CF and RF of group C were compared with group A(P ＜ 0.05 ),no significant discrepancy was observed between group B and C (P ＞ 0.05 ).( 2 ) In the elevated plus maze test,the result was similar to the open field test.(3)On day 1 after blasting injury,it was significant distinction that the level of serum corticosterone of group B,C and D (( 153.15 ± 44.50) ng/ml,( 132.72 ±78.77)ng/ml,(96.16 ±8.96)ng/ml respectively)were higher than group A(P＜0.05).Finally,the level of serum corticosterone of group B,C and D were lower than group A on day 28 (P ＜ 0.05 ).ConclusionBLI model successfully induces acute stress disorder(ASD) of rots which behaved like anxiety,fear,hyperarousal and avoidance,and promots furtherly the development of ASD to PTSD,and establishes the modle of acute PTSD.

To explore the effect of comprehensive management on psychological influence in children with asthma, 60 cases with asthma was administrated by WHO global comprehensive strategy for the management of asthma including the persistent use of beclomethaone with the intermittent inhalation of salbutanmol, the lung function monitored by peak flow meter, the detection and avoidance of the induced factors, the management of the social education and the psychological intervention. All children on comprehensive management were followed one year for observation. The results showed that the rate of the total effect was 98.3%. There were all decrease significantly in the rate of the hospitalization, the rate of the emergency, and the rate of the absence for school. It was obvious that asthmatic children and their parents's confidence for the treatment of asthma enhanced significantly.Their psychological disturbance, the school grade, and the life quality were also obtained advanced improvement.

We compared the total errors observed from both precision and accuracy validation experiments with defined medically allowable errors for each quantitative test,and used Westgard's method evaluation decision chart for initial judgement of the acceptability of method validation performance. Moreover,we need to judge the acceptability of other method validation parameters,so that we could integratedly assess and judge whether the testing system is acceptable to use in the laboratory.

[Objective]To evaluate the results of treatment with arthroscope and high tibial osteotomy with fixation of staple made of retention alligation for osteoarthritis of the knee,and to discuss the indication for this technique.[Method]From March 1999 to May 2003,42 arthroscopic treatment and high tibial osteotomies were performed in 34 patients.There were 6 men(8 knees)and 28 women(34 knees,with a mean age of 54.2 years(ranged,42～67 years.The average postoperative follow-up was 36 months(ranged,16～44 months.The indications for high tibial osteteotomy were unicompartmental osteoarthritis and varus malalignment.After arthroscopic treatment,a lateral closing-wedge osteotomy was performed with fixation of staple made of retention alligation.The arthroscopic examination showed:plica synovialis in l0 knees,medial meniscus injuries in 12 knees,lateral meniscus injuries in 6 knees,articular cartilage injuries in 20 knees,body loose in joint in 7 knees,intercondylar fossa stenosis in 9 knees.Common peroneal nerve was not exposed and the periosteum opposite to the insicion position was left intact for sake of stability and acted as a hinge around which the wedge osteotomy was closed.The patients were reexamined to obtain a knee score,to make lateral andanteroposterior radiograph of the involved knee with the patient standing.[Result]During the follow-up,the patients showed satifying pain relief,improvement of joint function,correction of yams deformity.The average preoperative knee score was 53.714?6.7,The average postoperative knee score at the time of the latest follow-up was 91.02?7.7.Comparing preoperative with postoperative,there were significant differences(P

Objective To study the role of the expression of P-selectin and intercellular adhesion molecule-1(ICAM-1) in hamster to rat concordant cardiac xenotransplantation.Methods Intra-(abdominal) cardiac transplantation was performed by using SD rats as recipients of Golden Syrian(hamster) hearts.The rats were divided into 4 groups randomly: group I(n=15),unmodified(recipients) were used as control; group II(n=15),splenectomy at day 0;group III(n=15),the rats were treated with cyclosporine A(CsA) 10 mg/kg every day from day 0;group IV(n=15),splenectomy in combined with CsA.The survival of hamster hearts was observed in each group.The xenograft was harvested at rejection and scheduled time in accordance with the experimental design,and analyzed for histology.The expression of P-selectin and ICAM-1 was detected by immunohistochemistry in xenograft after xenotransplantation.Results The mean survival time of the xenograft in group IV was 34.20?8.98 days,which was significantly longer in groups I,II and III (P

Objective To explore the relationship between pain of prostatitis and activation of glia cells in spinal cord. Methods To investigate the activation of astroglia cells and microglia cells in spinal cord after irritation of the prostate of the rats with complete Freund′s adjuvant (CFA) at different time using immunohistochemical staining. Results Activation of astroglia cells and microglia cells were significantly increased in deeper laminae and superficial laminae of the dorsal horn of L_6-S_1 spinal cord on the third day, tenth day and twenty-eighth day after CFA irritation of the prostate, and the most obvious activation occurred on the tenth day. Conclusions Activation of glia cells in spinal cord may play an important role in the neuropathological process of the pain of prostatic inflammation. The molecular mechanisms should be further explored.

Objective To investigate the role of Ca 2+ signaling in the overexpression of detrusor smooth muscle cell connexin 43 by cyclic stretch in vitro. Methods The detrusor smooth muscle cells (DSMC) grown on collagen-coated silicone membranes were subjected to cyclic stretch-relaxation. The Cx43 mRNA in DSMC were detected with RT-PCR, and the concentration of intracellular free Ca 2+ in DSMC was measured by confocal microscopy in conjunction with the calcium indicator, Fura-3 (Molecular Probes). Results The overexpression of Cx43 mRNA induced by cyclic stretch was significantly inhibited by EGTA.The increase of intracellular free Ca 2+ induced by stretch was also inhibited completely by EGTA, 61.95% by GdCl3, 29.98% by Nifedipine, 87.98% by Ryanodine and Thapsigargin. Conclusion The stretch-induced Ca 2+ entry, via the Ca 2+-induced Ca 2+ release mechanism, may play an important role in DSMC connexin 43 overexpression induced by cyclic stretch.
