Adult albino rats were exposed to simulated high altitude of 5000 m for 72 hours. Mild degree of interstitial pulmonary edema was observed under light microscope. Rats with the left lung excised were subjected to hypoxice of the same degree for 48 hours. On histologic examinations interstitial edema of the right lung was more obvious than that of the previous group. In isolated alveolus or in small groups of alveoli, edematous fluid could he seen.There were perivascular and peribronchial "Cuffs". The former were supposedto be accumulation of edema fluid leaking from the capillaries at the level of alveoli. The latter might be the result of extension of perivascular fluid to the peribrochial space.Excision of the left lung may result in a rise in pulmonary arterial pressure and over perfusion in certain areas remaining lung. Hypoxia may intensify the above changes. Pulmonary hypertension and overperfusion may in force promote the genesis of pulmonary edema.

OBJECTIVE To investigate the transgenerational effects of a hypothala mic-pituitary-ad-renal (HPA)axis -associated neuroendocrine metabolic progra mming alteration fro m F1 to adult second generation (F2)with prenatal ethanol ingestion.METHODS Pregnant Wistar rats were ad ministered with ethanol (4 mg·kg -1·d -1 )fro m gestational day 1 1 until delivery.F1 rats were fed a high-fat diet fro m postnatal week 4 (PW4)and were cross-mated in PW 16 -20.F2 rats were fed a standard diet fro m PW4 and rectal te mperature was measured in PW20,oral glucose tolerance test (OGTT)was con-ducted in PW21 ,blood sa mples and hypothala mus were collected in PW24 to investigate seru m lipids and HPA axis activity.RESULTS Co mparing to the F2 control group ,rectal te mperature in F2 ethanol group were higher (P<0.01 ),sugar tolerance in F2 male group was i mpaired (P<0.05),seru m corti-costerone and hypothala mus arginine vasopressin (AVP) mRNA were increased (P <0.05);seru m insulin were decreased (P<0.05)and male rats showed i mpaired glucose tolerance (P<0.05);seru m high-density lipoproteincholesterol (HDL-C)decrease (P <0.05)and total cholesterol (TCH)/HDL-C and low density lipoproteincholesterol (LDL-C)/HDL-C ratios were markedly increased (P <0.05,P <0.01 ).CONCLUSION Prenatal ethanol exposure induced metabolic syndro me has transgenerational effects,which may originate fro m the intrauterine progra mming of altered HPA axis-associated neuroen-docrine metabolis m.

To understand the Escherichia coli (E .coli) O157∶ H7 isolated from cow in Zhengzhou ,Henan Province ,a total of 146 samples of cow fecal and milk were collected in the different farms ,and E .coli O157∶ H7 was detected with mul-tiplex polymerase chain reaction (PCR) in our laboratory .Then the biochemical characteristics ,growth dynamic ,the biofilm formation ,and the toxin genes of the E .coli O157∶ H7 isolates were analyzed .The results showed that 2 strains of E .coli O157∶H7 were found ,with the detection rate of 1 .4% ,and the isolates were named as L1 and L2 in current study ,respec-tively .The E .coli O157∶H7 clinical isolates had the same biochemical characteristics with that of the typical E .coli .The L1 and L2 isolates presented similar growth curve ,which entered into the log phase earlier than that of the standard strain .L1 strain formed thick ,confluent ,complete biofilm after 48 hours post-inoculation ,and the biofilm of L2 strain was formed com-pletely in 36 hours .The two E .coli O157∶ H7 isolates were positive with eaeA and hlyA genes ,and the L1 strain also carried the Stx2 virulence gene .Our results reinforce the epidemiological data of E .coli O157∶H7 ,and underscore the need for more effective surveillance of animal-derived E .coli O157∶H7 isolates in Zhengzhou City ,China .

Objective To evaluate endovascular therapy and open surgery for subclavian artery occlusion disease. Methods In this study, 69 patients received endovascular therapy (44 patients)or open surgery(25 patients)from January 2002 to July 2007.Balloon dilatation was carried out in 3 cases and 43 stents was placed in 41 cases. Results All procedures were successful. In endovascular therapy group, the ratio of healthy/dieased side of mean blood pressure was improved from 0.66±0.14 to 0.96±0.13(t=9.532,P＜0.001＝;in surgery group, the ratio improved from 0.63±0.16 to 0.95±0.18(t=8.236,P＜0.001＝.Sixty-one discharged patients were followed up for 2～49 months(mean 16.7 months),in endovascular group, restenosis occurred in 1 patient 1 year after the therapy, in surgery group, all prothesis remained patent and there was no complication related to prothesis. Conclusions Both endovascular therapy and surgery were the effective methods for subclavian artery occlusion, and endovascular therapy is preferred for less invasiveness.

Objective To evaluate surgical therapy for ruptured aortoiliac artery. Method Between Apr 1984 and Dec 2003, 23 patients of ruptured aortoiliac artery were admitted with ruptured aortoiliac artery aneurysm in 18 cases and traumatic artery rupture in 5 patients. Two patients were treated with direct vascular repair and 21 patients underwent prosthetic grafts replacement. Result Four cases died perioperatively including 2 patients dying of acute renal failure, one of upper gastrointestinal heamorrhage caused by stress ulcer at 48 h after operation, and one of respiratory failure in 72 h. Conclusion Based on the etiology emergency operations should be performed on patients of ruptured aortoiliac artery by repairing or prosthetic grafts replacement.

Objective To compare the effect after endovascular repair (EVAR) or open repair (OR) of ruptured abdominal aortic aneurysm (rAAA) in Department of Vascular Surgery,Beijing Anzhen Hospital.Methods Clinical data of 46 repaired rAAAs patients was retrospectively analyzed from 2005 to 2015.The difference between the EVAR group and the OR group in perioperative mortality,operation time,ICU stay,blood transfused,length of stay (LOS),complication rate were compared by x2 test and t test.Results 18 rAAA patients were repaired by EVAR,aged from 51 to 91 with a mean of (68 ±9).28 were repaired by OR,aged from 41 to 83 with a mean of (70 ± 11).Perioperative mortality was 21.0％ for EVAR and 28.6％ for OR (P ＞0.05).LOS was (15.3 ±9.5) days for EVAR,and (23.9 ± 10.5) days for OR (P ＜0.05).Blood transfused was (3 210 ± 3 780) ml for EVAR and (4 814 ± 3 392) ml for OR (P＜0.05).ICU stay time was (7.7 ±4.2) d for EVAR and (4.2 ±2.5) d for OR (P＜0.05).Conclusion EVAR is a reliable approach for the treatment of acute rAAA.
