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 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.

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.

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 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.

Objective To observe the therapeutic effect of Qilin Xintongshu pill for treatment of patients with non-ST segment elevation acute coronary syndromes(NSTE-ACS)accompanied by gastrointestinal bleeding (GIB). Methods A prospective randomized controlled trial was conducted. A total of 67 hospitalized patients in Cardiovascular Department of Qionghai City Hospital of Traditional Chinese Medicine were divided into therapy group(35 cases)and control group(32 cases). Both groups were given conventional medical treatment(except anti-coagulative agent). In the therapy group,the patients received Qilin Xintongshu pill(the ingredients consisting of panax pseudo-ginsen,dragon's blood,immature orange fruit,etc.)oral administration,once 5 mg and 3 times a day,while in the control group,the patients accepted clopidogrel orally,once 75 g and once a day,the therapeutic course in both groups being 30 days. The major cardiovascular events(such as death,a newly-happened myocardial infarction(MI),MI secondary,obstinately ischemia)and incidence of massive hemorrhage of gastrointestinal tract were compared between the two groups,and the adverse events were observed. Results After treatment,the incidence of cardiovascular events and massive hemorrhage of gastrointestinal tract in the therapy group were decreased significantly compared to those in the control group 〔incidence of cardiovascular events:8.57%(3/35)vs. 28.13%(9/32), incidence of massive hemorrhage of gastrointestinal tract:2.86%(1/35)vs. 21.88%(7/32),both P<0.05〕. Adverse events were not observed in both groups,and the examinations of blood,urine,liver and renal functions were of no abnormalities before and after treatment. Conclusion Qilin Xintongshu pill can effectively reduce the incidences of cardiovascular events and massive hemorrhage of gastrointestinal tract in patients with NSTE-ACS accompanied by GIB in the therapeutic course of 30 days,therefore this traditional Chinese herbal medicine is an ideal agent for treatment of such disease.

Objective To investigate the correlation of the expressions of P170,topoisomerase Ⅱ(TOPⅡ)and the proliferation in gliomas.Methods Ki-67 was used as the marker of the proliferation in gliomas.The expressions of P170,TOPⅡ and Ki-67 were tested by S-P immunohistochemical technique using monoclonal antibody to their protein in 54 cases of low-grade gliomas(WHO Ⅰ～Ⅱ grade)and 54 cases of high-grade gliomas(WHO Ⅲ～Ⅳ grade),analysis of the clinical and follow-up were performed.Results The expressions of P170,TOPⅡ and Ki-67 had significant differences between low-grade and high-grade gliomas(P<0.01).Correlation analysis showed that the expression of P170 was negatively related with Ki-67(r=-0.276,P=0.019);the expression of TOPⅡ was positively related with Ki-67(r= 0.637,P<0.001);there was no correlation between the expressions of P170 and TOPⅡ.Conclusion The expressions of P170 and TOPⅡ are associated with the malignant prognosis in gliomas.

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 report a rare type of aortic arch aneurysm. Methods: Three cases of aortic arch aneurysm derived from the fourth aortic arch were retrospectively analyzed. The pathogenesis and treatment of this type of aortic arch aneurysm were investigated. Results:Most of the aneurysm body was located in the Z2 zone, which was the stem from the fourth aortic arch in the embryonic development period. All of the 3 cases could not be explained by common etiology. We speculated that the cause might be developmental anomaly of the fourth aortic arch. All the 3 aortic arch aneurysms were totally ex-cluded with a covered stent. The technical success rate was 100%. Endoleak of typeⅠwas seen in one case, which was resolved in a later open surgery. During the follow-up, no type of complications was found. Conclusion:To the best of our knowledge, this is the first report of this type of aortic arch aneurysm. The cause may be developmental anomaly of the fourth aortic arch. Endovascular treatment of this type of aortic arch aneurysm is feasible.
