Caveolin are a family that proteins are highly conserved and located at the mammalian plasma membrane.They include four isoforms:Cav-1,Cav-2,Cav-3 and Cav-4.Caveolin proteins are implicated in endocytosis,lipid metabolism and cellular signaling.There is recent evidence that Cav-1 expression levels in tumour have been associated with tumour growth and metastasis,stromal car-1 expression downregulated have been also associated with mutli-tumor metastasis.

Despite the general agreement that calculation ability is an important component of cognition,and a comprehensive cognitive evaluation should include testing for calculation ability,there is a significant paucity in study and evaluation of acalculia.In this paper,the concepts and classification of acalculia are proposed;main neuropsychological theoretical models and cerebral mechanisms are presented;clinical appearances,standard testing instruments and related study of acalculia are intensively reviewed;finally,rehabilitation training of acalculia is initially discussed.

Objective To explore the value of the square for intracranial puncture orientation applying in the intracranial hematoma microinvasive craniopuncture scavenging technique. Methods Fifty-one patients with hypertensive cerebral hemorrhage were randomly enrolled into the orientation square group( n=27)and the CT orientation routine group (n=24). The puncture point was fixed by certain wayin each group. Both groups received the same intracranial hematoma microinvasive craniopuncture scavenging technique. The punctural precision,the time spended for puncture orientation and the curative effect in two group were observed and compared. Results The deflected rate(18.5%)of the orientation square group was lower than that routine group significantly(50.0%)(P

[Objective]To determine the effect of Oxfenmino hydrochloric acid on delayed allergic reaction in mouse. [ Method ] 120 ICR mice weighing 18~22g, half female and half male, were randomly and averagely divided into 6 groups according to weight:control group and model group (treated with distilled water at a dosage of 10ml/kg), three Oxfenmino hydrochloric acid groups (treated with Oxfenmino hydrochloric acid at a dosage of 10.0mg/kg, 5.0mg/kg and 2.5mg/kg respectively) and positive drug group (treated with CsA at a dosage of 15mg/kg); they were orally administered one time every day. After a continuous week of administration, all the groups were smeared evenly with 1%DNFB solution on the abdomen for allergy except the control group. Five days after allergy, 1%DNFB solution was smeared to right ear of all mice to stimulate the allergic reaction except that the control group was smeared with non-allergenic substance. 24 hours after attack, the auricle swelling, spleen index and thymus index in right mouse were determined. [ Result] Different dosages of Oxfenmino hydrochloric acid benefited to reduce auricle swelling, spleen index and thymus index in mouse with allergic reaction induced by DNFB at different degree. [ Conclusion] Oxfenmino hydrochloric acid can inhibit the delayed allergic reaction in mouse induced by DNFB and depress the ability of specific cell-mediated immunity.

Aim To establish a rat aortic calcification sub-chronic model induced by vitamin D3 and nicotine.Methods The vascular calcification model was produced by vitamin D3(300 kIU?kg-1,im) plus nicotine(25 mg?kg-1,5 ml?kg-1,po).Rat body weight and blood pressure were monitored on a regular basis.Ratio of heart to body weight,plasma calcium,plasma phosphate content,vascular calcium content,Von Kossa staining,activity of alkaline phosphatase(ALP) and 45Ca deposition in aorta were measured as the index of calcification at the 8th and the 16th week.Results Compared with control group,the VDN group rats showed higher values of blood pressure from the 3rd week(all P

Objective To explore the clinical significance of changes of umbilical artery and amniotic fluid vascular endothelial growth factor (VEGF) level in newborn infants with asphyxia. Methods The VEGF levels in umbilical artery and amniotic fluid were detected by ELSIA in 67 newborn infants with asphyxia (asphyxia group) and 44 normal term newborn infants (control group). Results The VEGF level of umbilical artery ( 674?150) ng/L and amniotic fluid (225?78) ng/L in asphyxia groups were significantly higher than that of umbilical artery (129?30) ng/L and amniotic fluid (57?4) ng/L in control group ( P

Objective To investigate errors and mechanism of acalculia in patients with brain injury.Methods Forty patients with brain injury and forty-eight normal adults who were matched in age and years of education were tested with EC301 standardized battery. Patients were divided into the left-brain damaged (LBD) group (n=20), right-brain damaged (RBD) group (n=9) and bilateral brain damaged (BBD) group (n=11). The data of all subjects were statistical analyzed.Results Both total scores and scores of 27 out of 31 items were remarkable lower in patients than those in the normal control group ( P<0.05). The total scores and items' scores for number sequences, numerical transcodings were significantly lower in LBD group than those in RBD group ( P<0.05). Total scores and each items' score did not significantly differ between BBD group and LBD group, or between BBD group and RBD group ( P>0.05).Conclusion The abilities of number processing and calculation are impaired in patients with brain injury. There is either association or dissociation in terms of performance of acalculia and aphasia in LBD patients. Visuospatial impairment is related to performance of acalculia in RBD patients.

Objective To investigate natural killer(NK) and NKT cells in acute pancreatitis(AP).Methods Changes of NK and NKT cells in peripheral blood of 86 AP cases were detected using muhiparameter flow cytometry.Results Compared with control group,the NKT cells decreased in AP patients (t =5.23,P =0.00),but NK cells didn't (t =-1.15,P =0.25).NKT cells in severe SAP and mnoderate MAP were lower than that in the control group (t =-3.92,P =0.00;t =4.84,P =0.00).There was no statistically significant difference of NK cells between MAP and the controls (t =-0.54,P =0.59),but NK cells in SAP group was obviously higher than that in control group (t =3.12,P =0.00).After one week treatment,NK cells significantly decreased (t =8.43,P =0.00).NKT cells were higher than control group (t =-4.44,P =0.00).Dynamic monitoring in AP patients found continuous declination in NK cells,and NKT cells experienced an increase before a falling.Conclusion Monitoring of NK and NKT cells can be used as an important index for the severity and response to treatment in acute pancreatitis.

Objective To compare the differences between external standard method and relative correction factor method for determination of the flavonoids from Sorbus tianschanica Rupr.Methods Using HPLC external standard method for determination of hyperoside,rutin,isoquercitrin,quercetin-3-O-(6″-O-malonyl)-β-D-glucoside,astragalin and Kaempferol-3-O-(6″-O-malonyl)-β-D-glucopyranoside in Sorbus tianschanica Rupr.,HPLC relative correction factor method was adopted to establish relative correction factor of the other five flavonoids above with hyperoside as reference.The difference was evaluated by comparing the external standard method with the relative correction factor method.Results There was no significant difference between the T test external standard method and relative correction factor method(P>0.05).Conclusion External standard method and relative correction factor method can be used for determination of the flavonoids from Sorbus tianschanica Rupr.,but in the case of lack of reference substance or mass detection,using the relative correction factor method for determination of rutin,hyperoside isoquercitrin,quercetin-3-O-(6″-O-malonyl)-β-D-glucoside,astragalin and kaempferol-3-O-(6″-O-malonyl)-β-D-glucopyranoside in Sorbus tianschanica Rupr.It was more feasible and it can be used as a new quality evaluation method in determination of flavonoid components from Sorbus tianschanica Rupr.
