AIM:To observe the relation between astroglial activation state and ischemic tolerance in the gerbil hippocampus. METHOD: Bilateral occlusion of common carotid arteries and immunofluorescent methods in the gerbil hippocampal tissue. Slices were used. The morphological changes of the neurons were observed by light microscopy.RESULTS:Pretreatment with 2 minute bilateral carotid artery occlusion produced protective effects of CA 1 neurons. Glial fibrillary acidic protein (GFAP) staining showed weak positive cells in control group. Most of GFAP positive cells showed weak and middle positive cells after recirculation 1d and 2d following ischemic 3.5 min and preconditioning of the brain with sublethal ischemia respectively.CONCLUSION:Astroglial played an important role in cerebral ischemia. It is possible that state of astroglial activation related to neuronal survival in ischemic tolerance.

Objective To investigate the diagnostic and predict vaIue of procalcitonin (PCT) in ICU patients with sepsis and the correlation between PCT concentration and positive results of bacterial culture.Methods A total of 278 patients with sepsis were admitted into emergency ICU,general ICU and respiratory ICU from October 2011 to September 2012.Of them,193 patients had definite microbial infection evidence.Serum PCT levels among groups of different pathogens were compared.The analysis of correlation between the PCT concentration of the first assay was got after admission and short-term prognosis was evaluated.The correlation between PCT level and positive results of bacterial culture was also evaluated.Results Spearman correlation analysis showed that serum PCT levels of bacterial infections in patients with sepsis were significantly higher than those of the non-bacterial infections in patients with sepsis (P =0.001).And there was a positive correlation between the PCT concentration of the first specimen after admission and 7-day in-hospital mortality in patients with sepsis due to bacterial infections (r =0.277,P =0.004).The patients with PCT levels greater than 2 ng/ml had high vulnerability to bacterial infection Conclusions The PCT concentration of the first assay after admission was positively correlated to 7-day mortality in ICU patients with sepsis due to bacterial infections.The serum PCT concentration indicated the severity of host response to the bacterial infection.And etiological evidence directly showed pathogenic factors.Both of PCT and etiological evidence related to bacterial infection,reflected different aspects of bacterial infection.

Objective To evaluate the diagnostic and predict value of procalcitonin (PCT) levels in patients diagnosis of sepsis with immune system defect in the intensive care unit (ICU).Methods This is a retrospective analysis.We enrolled 278 patients diagnosis of sepsis in Emergency ICU,general ICU and Respiratory ICU in Renmin Hospital of Wuhan University from October 2011 to September 2012.Among them,122 patients have normal immune function and 156 patients have auto-immune system diseases or/and requiring corticosteroids or chemotherapy.According to the APACHE Ⅱ score,patients were divided into low-risk group,middle-risk group and high-risk group,and their PCT levels were compared.Logistic regression analysis of the multiple factors was used to screen independent risk factors for predicting 7 days' mortality.The predictive ability was also evaluated and compared between the first time of PCT concentration after admission and dynamic change of PCT within the first week with area under receiver operator's characteristic curve (ROC curve,AUC).Result The results of Spearman correlation analysis showed that there was a significant positive correlation between the patients' PCT concentration and APACHE Ⅱ score (r =0.979,P ＜ 0.05).And there was a positive correlation between the first PCT concentration after admission and 7 days' mortality in-hospital (r =0.826,P ＜ 0.05).Multiple factors logistic regression analysis indicated that both the first time PCT concentration after admission and APACHE Ⅱ score of patients were independent risk factors for predicting 7 days' mortality (PCT OR =1.77,95％ CI =1.28-3.83,P =0.0023).The warning value of 7 days' mortality for patients with normal immune function was PCT≥7.18 ng/ml and for those with abnormal immune function was PCT ≥ 3.52 ng/ml.Compared to dynamic monitoring of PCT,there was no significant difference in sensitivity but specificity is less than the dynamic monitoring of PCT.Conclusions The diagnostic and predict value of procalcitonin (PCT) levels were not affected by the immuno-suppressive therapy.The first time PCT concentration after admission was an independent risk factor for predict of 7 days' mortality in ICU patients with sepsis.The PCT warning value of the sepsis patients with abnormal immune function was much lower compared to those with normal immune function.

Objective To investigate the assistant method for improving and promoting nervous movement functional recovery on neonate hypoxie ischemic encephalopathy. Methods Eighty-five patients with neonate hypoxic ischemic encephalopathy were divided into two groups: observed group (45 cases) and control group(40 cases). Observed group added early exercises intervention on basis of routine synthetic drug treatment, compared to control group which just purely synthetic drug treatment with neonatal behavior neurological assessment (NBNA), mental development index (MDI) and psychomotor development index (PDI). Results NBNA at 14 days [(38.84±1.56)scores] in observed group was significantly higher than that in control group [(36.12±2.23)scores]. PDI at 6, 12 months and MDI at 12 months in observed group were significantly higher than those in control group. Conclusion Early exercises intervention can promote nervous movement functional recovery on neonate hypoxic ischemic encephalopathy, prevent or lessen brain injury sequels, elevate life quality for patients with neonate hypoxic ischemic encephalopathy.

Objective To evaluate the feasibility of endovascular repair for retrograde type A aortic dissection.Method 35 patients of retrograde type A aortic dissection admitted to Peking University People's Hospital from December 2001 to March 2014 were treated with endovascular repair.There were 33 males and 2 females with mean age of 46 ± 9 years.29 were on acute stage,2 on subacute stage and 4 on chronic stage.The entry tear was in the descending thoracic aorta in 32 cases,between the left subclavian artery and the left common carotid artery in one,and between the left common carotid artery and the innominate artery in two.Results Entry closure was achieved in all patients with a covered stent.2 patients died in 30 days postoperatively (5.7％).1 patient with two chimney developed acute renal artery embolized which was infused by false lumin (2.9％).One patient developed transient paraparesis after graft deployment(2.9％).During the follow-up period,the aortic remodeling is perfect,no entry tear was noted in the ascending thoracic aorta.All the endografts for preserving supra-aortic branches were patent.Conclusions The endovascular repair for retrograde type A aortic dissection is feasible and effective.

Methods The clinical data of 38 patients with splitting right hepatic duct and hepatolithiasis treated by operation were analyzed retrospectively. Results All the patients underwent operation. operative procedures were as follows: (1) in situ cholangioplasty of splitting right hepatic duct in 7 cases;(2) fenestration of splitting right hepatic with adjacent hepatic duct in 9 cases; (3) bilioplasty of splitting right hepatic duct with adjacent bile duct in 8 cases; (4) hepatic lobectomy or segmentectomy of splitting right hepatic duct in 14 cases. Postoperative complications developed in 6 cases, which were cured conservatively. There was no perioperative mortality. All patients were followed up for 5～16 years(averaged 9.2 years). Excellent rate was 78.9%,and residual stones were found in 26.3% of the patients . Conclusions Accurate localization and appropriate operation may get satisfactory result in treating patients with splitting right hepatic duct with hepatolithiasis and stenosis.

Objective To evaluate the clinical efficacy of Qilinxintongshu pill for treatment of critical patients with unstable angina pectoris (UAP) accompanied by upper alimentary tract damage.Methods A prospective randomized controlled trial was conducted. A total of 60 critical outpatients or inpatients with confirmed diagnosis of UAP accompanied by upper alimentary tract damage in Cardiology Department of Hospital of Traditional Chinese Medicine of Qionghai City from November 2011 to January 2015 were enrolled in the study, and they were assigned to a therapy group (30 cases) and a control group (30 cases) by table of random number. The conventional medical basic therapy was given to both groups, in addition, the patients in therapy group took Qilinxintongshu pill (made of notoginseng, dragon's blood, fruit of immature citron, etc.) 5 g once, three times a day, and the patients in control group orally administered clopidogrel 75 mg once a day, the therapeutic course being consecutive 30 days. After treatment, the rates of main cardiovascular events [including death, a newly-happened myocardial infarction (MI), and obstinate ischemia] and events of alimentary damage were compared between the two groups, and adverse effects were observed.Results There was no statistically significant difference in incidence of cardiovascular events between the therapy group and control group [6.7% (2/30) vs. 16.7% (5/30),P > 0.05]. The incidence of massive hemorrhage of gastrointestinal tract was significantly lower in therapy group than that in control group [10.0% (3/30) vs. 36.7% (11/30),P < 0.05]. In the treatment process, there was no significant untoward side effect, and no abnormalities in routine blood and urine tests, liver and renal functions were found.Conclusion Qilinxintongshu pill for treatment of critical patients with UAP accompanied by upper alimentary damage is safe and effective, and does not enhance the incidence of massive hemorrhage of gastrointestinal tract.

SUMMARY An involved internal iliac artery is usually embolized when performing endovascular aneu -rysm repair for aortoiliac or isolated iliac artery aneurysm .This can lead to complications such as buttock claudication ,colon ischaemia and erectile dysfunction .Iliac branch device ( IBD ) is an endograft de-signed specifically for iliac bifurcation to preserve internal iliac flow .It was performed with high technical success rates and encouraging mid-term patency .Here we report a case of right iliac aneurysm developed 3 years after endovascular aneurysm repair for an aortoiliac aneurysm , with the patient ’ s left internal ar-tery been sacrificed then .Using a handmade IBD , we excluded the aneurysm without occlusion of the ip-silateral internal iliac artery or any type of endoleak .Both the design and deployment of this IBD are dis-tinctive that we would like to share our experience with all the colleagues .

Objective To evaluate iliac artery rupture during endovascular treatment of aorto-iliac disease and treatment with covered stent.Methods From November 2008 to August 2014,iliac artery rupture happened in 8 patients of 225 patients of aorto-iliac artery disease admitted to our hospital.Clinical data of the 8 patients were analyzed retrospectively.Four were of intraoperative rupture and four were of delayed rupture.The aorto-iliac diease of all the 8 patients were TSAC D.Direct placement of a covered stent was performed in all the cases,except for one patient who refused further treatment.Results All of the procedures finally achieved technical success and all patients become hemodynamically stable.One patient was complicated with heart failure who died of multiple organ dysfunction syndrome.Another one died of aspiration.5 patients were followed up from 9-52 moths,average 9-52 moths without recurrence.Conclusions Iliac artery rupture is a serious and life-threatening complication in the endovascular treatment of aorto-iliac disease.Covered stent provided a safe and effective treatment for iliac perforations.

Objective To investigate risk factors of the prognosis of patients with severe fever with thrombocytopenia syndrome (SFTS).Methods From May 2012 to July 2014,17 cases of severe fever with thrombocytopenia syndrome in Renmin Hospital of Wuhan University were treated.Clinical data including history of epidemiology,clinical manifestations,complications,physical examination and laboratory test results on admission and the third day after admission were retrospectively analyzed and compared with the death group and recovery group by application of Spearman correlation analysis.Results Elderly male patients with neuropsychiatric symptoms,or abnormal liver function,or abnormal blood clotting function had higher risk of the poor prognosis.In SFTS patients,AST,ALT was significantly increased,AST 539 U/L (229.73,545.4) U/L (r =0.597,P =0.015) was a risk factor affecting prognosis.Elevated blood ammonia indicated serious liver dysfunction and neurological dysfunction which were manifested as irritability,delirium,and trembling limbs.In SFTS patients,platelets were significantly decreased accompanied with mouth ulcers / bleeding gums,gastrointestinal bleeding.PLT 24.88 × 10 9/L-1 (12.75,35.00) ×10 9/L-1 (r=0.557,P=0.005) or APTT 86.06 s (66.88,114.18) (r=0.798,P=0.001) or D-dimmer 9.79 mg / L (4.09,16.51) mg/L (r =0.597,P =0.015) are risk factors affecting poor prognosis.Conclusions On the third days after admission,AST,WBC,PLT,APTT,Ddimmer are risk factors for prognosis of patients with severe fever with thrombocytopenia syndrome infected by a novel bunyavirus.
