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 analyze the use situation and trend of cardiovascular and cerebrovascular drugs during 2007～2009 in a military sanatorium, and provide reference for the rational use of cardiovascular and cerebrovascular drugs and its essential medicines. METHODS: Cardiovascular and cerebrovascular drugs in the rehabilitation center during 2007～2009 were analyzed statistically in the respect of category, consumption sum and DDDs. RESULTS: The consumption sum and DDDs of cardiovascular and cerebrovascular drugs were increasing in the past three years. And its essential drugs account for 94.8%.The most widely used drugs were cerebrovascular drug, brain metabolism drug, nootropics and antihypertensive drugs. Oxiracetam and Xueshuantong were widely used cerebrovascular drug, brain metabolism drug and nootropics. Amlodipine were widely used antihypertensive drugs in the clinic. CONCLUSION: Cardiovascular and cerebrovascular drugs and its essential drugs were characterized with complex classification, numerous categories, extensive application and potential market demand, which require rational use of drug should be strengthened.

Objectives To establish a simple,quick,accurate serodiagnostic assay for detecting serum antibodies against Helicobacter pylori(H.pylori).Methods We established quick immunocolloidal gold filtration assay(DIGFA) by combining colloidal gold labelling technique with filtration method.145 sera from cases with H.pylori infection were detected by DIGFA,and the results were compared with that of ELISA and pathological examinations.In addition,blocking test and human IgG protein detection were conducted.The sensitivity,specificity of DIGFA were analysed.Besides,DIGFA was applied to investigate the H.pylori infection situation among persons of different ages.Results The coincidence rate reached 95 1% compared with the ELISA,and it was 88 8% compared with pathological the examination.The detectable minimum amount of IgG was 10?g/mL.The antibodies detected by DIGFA proved to be specific antibodies by blocking test.The human H.pylori infection rate among 216 persons reached 42 5% by DIGFA.Conclusions DIGFA can be applied effectively in clinical diagnosis and epidemiological survey.

Objective To investigate the common reasons,prophylaxes and treatment of postoperative complications in orthotopic liver transplantation (OLT).Method Seventy two patients who underwent OLT during recent three years were collected and analyzed retrospectively.Results OLT was performed on 50 cases with benign diseases including terminal liver cirrhosis 34;and 22 cases with and malignant diseases including hepato cellular carcinoma 19 cases.Fifty four complications were occurred postoperatively,including secondary abdominal cavity bleeding (4 cases ),severe infection of ascites (2 cases),stress gastric ulcer with bleeding and perforation (1 cases),biliary leak (6 cases),pulmonary infection (21 cases),and enteric fungal infection (5 cases).There were no primary dysfunction of liver and vascular complications.Follow up 2-41 months, without biliary complications and chronic liver dysfunction occurred 6 cases death postoperative,6 cases death on follow-up period.Total surrival rate is 83.33%, 32 cases alive more than 1 year,the longest surrival cases is 41 months postoperative.Conclusions It is suggested that the cases with cirrhosis are main indication for liver transplantation.The patients with liver cirrhosis always combinated of liverdisfunction,coagulopaphy,malnutrition and poor immune functions and we should pay attention to replace that of coagulation factors,antibiotics using and nutrition support perioperatively.Good surgical technique is the key point for preventing vascular complications.

To study the relationship between the density of muscarinic receptor (MR) subtype and the occurrence of bladder instability. The rat model of unstable bladder was established, and the density of MR subtype was determined in normal and unstable bladders. The results showed that there were only m 2 RNA and m 3 RNA present in the detrusor of normal and unstable bladders, and m 1, m 2 or m 3 mRNA subtypes were not detected. In the normal bladder, the amount of m 2 RNA (1 67?0 42) was obviously greater than m 3 RNA (0 64?0 19), and the ratio of them was 2 59∶1. In the unstable bladder, the density of both m 2 and m 3 increased to (2 03?0 65) and (1 53?0 46) respectively, and the increase of m 3 was more significant ( P

The purpose of this study was to compare the efficiency of 3 different methods in purifying engineered anti-HBsFab. Anti-HBsFab Supernatants containing anti-HBsFab were prepared by ultrasound lysis of host cells of anti-HBsFab positive clone. Anti-Fab-sepharose gel, streptococcal protein G-sepharose gel (Prot G gel) and Ni-NTA-agarose gel were used to purify Fabs according to the reagents protocols. Then the concentrations of purified proteins were determined. SDS-PAGE was used for the measurement of purified Fabs'purity. HBsAg based ELISA was chosen to determine the Fabs' bio-activity. The results indicated that Fab recovery of different gels in equal volume were different. The recovery of Ni-NTA GEL was greater than that of Prot G gel, and the recovery of Prot G gel was greater than that of anti-Fab gel. Purity of the Fab isolated by 3 different gels was confirmed by SDS-PAGE. The binding capacity of anti-HBs Fab to HBsAg of these three gels had no signifticant difference. Our data suggested that each method had its advantage and usage limitation, Ni-NTA method demonstrated much better performance in economy, management, and efficiency over the other two methods.
