Objective To investigate the accuracy of prognosis risk assessment and clinical applicability of Rockall (RS) and Blatchford scoring system (BRS) for acute nonvariceal upper gastrointestinal bleeding (ANVUGIB). Methods From January 2009 to December 2009, the clinical date 195 ANVUGIB patients who met the standards with complete information and treated in The First Affiliated Hospital of Anhui Medical University were recorded. Each patient's scores of RS and BRS were calculated for risk stratification. Patients were followed up for 30 days after discharged.Death or the prognosis of disease in 30 days after discharged was considered as clinical study endpoints.Checked prognostic capacity of these two scoring system. Results In the 195 patients, there were 150 years, mean age was 53.97±18.34 years. 90 patients' age was over sixty (elderly group), 105 less than sixty (non-elderly group). 182 patients survived (93.3%), while 13 dead (6.7%). In survival patients, 11were re-bleeding (5.6 %). Mortality ( 12.2 %, 11/90), the percentage of patients with comorbidities (43.3%, 39/90) and taking aspirin (24. 4%, 22/90) were higher in elderly patients than non-elderly patients (1.9%, 2/105; 16.2%, 17/105; 11.4%, 12/105 respectively)(P＜0.05).The AUC of RS in predicting risk of death was 0.742 (P=0.004) and re-bleeding was 0.469 (P=0.101). For BRS score system, the AUC of predicting risk of death was 0. 493 (P= 0. 067)and rebleeding was 0.341(P=0.092). The RS score was positively correlated with length of hospital stay,however there was no statistically significant between BRS score and length of hospital stay.Conclusion RS score system was good at predicting the risk of death, and the score was positively correlated with length of hospital stay. While it was poor in predicting the risk of re-bleeding. BRS performed poorly in predicting the risk of both death and re-bleeding, so it was not suitable for predicting the risk of hospitalized patients.

AIM: To study the inhibitive effects of valsartan and spironolactone on expression of insulin like growth factor 1 in cardiacmyocytes of spontaneously hypertensive rats. METHODS: 18 SHRs were randomly divided into 3 groups (n=6 in each): valsartan group treated with 30 mg?kg -1 ?d -1 valsartan, spironolactone group treated with 20 mg?kg -1 ?d -1 spironolactone, and control group treated with placebo. All were administrated by gastric perfusion. 6 WKY rats were served as control. After 13 weeks administration, the expressions of IGF 1 in cardiacmycytes were measured by immunohistochemistry and the IGF 1 concentrations in myocardium were measured by radiommunoassay. RESULTS: The expression of IGF 1 was higher in SHR group than that in the WKY group (P

Objective:To explore the risk factors of delayed traumatic intracranial hematoma (DTICH)followed by unilateral large decompressive craniectomy (LDC)and its influence in the prognosis of the severe traumatic brain injury (sTBI)patients,and to improve the successful rate of the rescue.Methods:The clinical data of 130 sTBI patients underwent unilateral LDC were retrospectively analyzed.The patients were divided into DTICH group (n=42)and non-DTICH group (n=88)according to whether the DTICH occurred after operation.The risk factors of DTICH and its influence were contrastively analyzed.Results:The analysis results of the clinical data of patients in two groups showed that preoperative GCS,time from trauma to operation,skull fracture,midline shift > 1 cm, basal cistern disappear,activated partial prothrombin time (APTT),fibrinogen (FIB),and thrombin time (TT) were significantly correlated with the appearance of DTICH (P<0.05).Multivariable Logistic regression analysis showed that the time from trauma to operation, skull fracture, basal cistern disappearing and FIB were the independent risk factors of DTICH (P<0.05).The analysis results of GOS 3 months after operation of the patients in two groups showed that the prognosis of the patients in DTICH group was significantly worse than that in non-DTICH group (P<0.01 ).Conclusion:For those patients who accompanied with shorter time from trauma to operation,skull fracture,basal cistern disappearing and FIB decrease,the appearance of DTICH should be paid attention.DTICH can affect the prognosis of patients;prevention and early diagnosis are crucial to improve the prognosis of patients.

Objective:To observe the protective effect of acupuncture plus mild hypothermia on brain tissues in rats with cerebral ischemia-reperfusion injury (CIRI), and the influence on protein expression levels of phosphorylated Raf-1, MEK-2 and ERK1/2 in the mitogen-activated protein kinase (MAPK)/extracellular regulated protein kinases (ERK) pathway, and to explore the mechanism of acupuncture plus mild hypothermia therapy for the ischemic stroke. Methods:Ninety Sprague-Dawley (SD) rats were randomly divided into a blank control group, a sham operation group, a model group, an acupuncture group, a mild hypothermia group and an acupuncture plus mild hypothermia group, 15 rats in each group. Except the rats in the blank control group, the remaining rats were used to prepare the middle cerebral artery occlusion (MCAO) models according to the modified occlusion method using lines, while only the occlusion lines were inserted without blocking the brain arteries of rats in the sham operation group. When the vital signs of rats were stable, rats in the blank control group did not receive any intervention; rats in the sham operation group and the model group received fastening without treatment; rats in the acupuncture group, the mild hypothermia group, and the acupuncture plus mild hypothermia group were treated with the corresponding therapeutic methods. 72 h later, observed neurologic injury score, evaluated infarction area ratio by 2,3,5-tripheyl tetrazolium chloride (TTC) staining, determined apoptosis by TUNEL assay, and measured the phosphorylated Raf-1, MEK-2 and ERK1/2 protein expression levels in rat ischemic hippocampal tissues by Western blot assay. Results: Compared with the blank control group and the sham operation group, after modeling, the neurologic injury score, infarction area ratio and apoptotic cells were increased, and phosphorylated Raf-1, MEK-2 and ERK1/2 protein expression levels were significantly increased in the model group; the differences were statistically significant (P<0.05 orP<0.01). Compared with the model group, after acupuncture or mild hypothermia therapy, neurologic injury score and infarction area ratio were decreased; apoptotic cells and phosphorylated Raf-1, MEK-2 and ERK1/2 protein expression levels were significantly decreased; the differences were statistically significant (P<0.05 orP<0.01). Compared with the acupuncture group, neurologic injury score and phosphorylated Raf-1, MEK-2 and ERK1/2 protein expression levels were decreased in the acupuncture plus mild hypothermia group; differences between the groups were statistically significant (P<0.05 or P<0.01). Compared with the mild hypothermia group, phosphorylated Raf-1, MEK-2 and ERK1/2 protein expression levels decreased in the acupuncture plus mild hypothermia group, and differences were statistically significant (P<0.01). Conclusion:Acupuncture or mild hypothermia therapy can improve neurologic injury, reduce infarction area and apoptosis, which brought about protective effect on the brain tissues, in the MCAO model. The protective effect of acupuncture plus mild hypothermia group is the strongest. The mechanism may involve the MAPK/ERK pathway, by reducing the phosphorylated Raf-1, MEK-2 and ERK1/2 protein expression levels.

Objective To study the rationality and possibility of 64 slice spiral CT in the examination of the temporal bone at low dose.Methods The same CT technique and temporal bone mode as those for clinical CT were used,two cranium specimens(four ears)were scanned with Somatom Sensation 64-slice spiral CT at different mA(380,300,200,160,120,80),and muhi-planar reformation was performed.The CT dose index at different mA groups were measured by 10 cm pencil ionization chamber and head dose phantom.Four anatomic structures on axial images(subarcuate fossa,tendon of tensor tympani, facial recess,etc),four anatomic structures on coronal images(scute,crista transversa,fenestra cochleae, etc)and six anatomic structures on double oblique images(malleus,incus,stirrup bone,upper bony semicircular,etc)were chosen to evaluate and grade the reformation images among different mA groups,and to determine the minimum mA value.Ten ears of five patients were used to test the validity of the minimum mA value.Results CT radiation dose was significantly reduced from(47.8?2.7)to(20.1?2.0)raCy (P
