The angle of tibial torsion is an inherent angle in human bodies.The angle has been to knew of clinical workers.But the research of mechanism for angle of tibial torsion and relationship with some disease still in initial stage.Recent years,the angle of tibial torsion has been noticed with the concept of torsionaldeform appearance.This paper summarizes measurement of the angle of tibial torsion andits advancement of correlated research.

Objective To study the role and mechanism of A2AR activation in tau hyperphosphorylation after brain injury.Methods SD rats were cultured with no specific pathogen level.SH-SY5Y was cultured.The rats were treated with CGS21680 solution and DMSO and SH-SY5Y respectively.The CGS21680 solution and sb216763, H-89, or Only add ZM241385, the control group plus DMSO, compared with each group tau hyperphosphorylation.Results The phosphorylation level of tau protein in SH-SY5Y cells was significantly higher than that in the control group (P<0.05).The phosphorylation level of tau protein in the primary hippocampal neurons of rats was significantly higher than that of the control group (P<0.05).The levels of tau protein phosphorylation in group 2 and group 3 were significantly higher than those in control group (P<0.05).The expression of tau in group 4 and group 5 was statistically significant (P<0.05)There was no significant difference in phosphorylation level between the two groups.Conclusion A2AR activation can activate kinase A and GSK-3β after brain injury, leading to tau hyperphosphorylation.

Objective To investigate the clinical effect of continuous blood purification therapy in patients with severe heart failure and renal failure.Methods The clinical data of 38 patients with severe heart failure and renal failure treated by continuous blood purification were analyzed retrospectively.Heart rate,mean blood pressure, APACHE II score,Boston score,blood biochemistry,blood gas analysis and cardiac function changes were compared before and after the treatment of continuous blood purification.Results After treatment 12h and 72h,patients breath-ing[(19.24 ±2.88)times/min],heart rate[(88.57 ±15.68)times/min],APACHE Ⅱ [(14.28 ±3.26)points] and the score of Boston[(6.27 ±1.25 )points]were significantly decreased compared with those before treatment [(35.68 ±5.97)time /min,(131.24 ±24.26)time /min,(26.34 ±5.96)points,(17.88 ±2.87)points],and the differences were statistically significant (t =3.13 3.45,2.12,4.11,3.67,5.68,3.44,609,all P <0.05).38 cases of severe heart failure with renal failure after continuous blood purification treatment,markedly effective in 16 cases, effective in 12 cases,ineffective in 10 cases,the total effective rate was 73.68%.Patients after continuous blood purification treatment,the SCr[(168.15 ±31.16)μmol/L],BUN [(13.13 ±3.44)mmol/L]were significantly decreased.pH[(7.41 ±0.13)],HCO3 [(25.57 ±5.11)mmol/L],PaO2 [(88.26 ±7.72)mmHg],SaO2 [(96.43 ± 3.14)%]and blood biochemistry and blood gas index decreased markedly,and the differences were statistically significant (t =4.55,3.21,2.11,3.45,673,4.21,all P <0.05).After the examination of echocardiography,stroke volume (SV)[(59.31 ±6.58)mL],cardiac output (CO)[(4.57 ±0.62)L/min]and left ventricular ejection fraction (LVEF)[(68.12 ±4.88)%]increased significantly compared with before treatment,and the differences were statistically significant (t =4.33,5.12,367,all P <0.05).Conclusion Continuous blood purification could effectively maintain the hemodynamic stability of patients,and is safe and effective in the treatment of severe heart failure with renal failure.

In the recent few years,apart from the development of interventional technology,the development of new kinds material for packing intracranial aneurysms has hastened the promotion of endovascular interventional treatment greatly. Microvention company introduces lately Hydrocoil,a kind of hydro-agglutinated microspring coil which adopts a special hydrolink detachment technology,enriching the methods of endovascular treatment for cerebral aneurysms. Hydrocoil is a traditional platinum coil coated with expandable,unabsorble hydrogel material,which can improve the filling volume proportion of the aneurysm. At present it has been initially applied in clinic. This article summarizes the characteristics,the preclinical study,and the clinical application of Hydrocoil.(J Intervent Radiol,2007,16: 710-713)

NKR and TLR are most important receptor superfamilies in innate immunity and act as first line of host defense against infection. Those receptors exert peculiar recognition mechanisms to sense danger signals and distinguish infectious nonself from noninfectious self. More importantly, they coordinate and regulate each other and therefore play major roles in initiation of innate immunity and also help to direct adaptive immune responses. The importance of recognition and interaction of those receptors are highlighted. The precise mechanisms can be harnessed to aid the rational design of therapy against infection, inflammation, cancer or autoimmune diseases.

We used MTT assay to test the cellular cytotoxicity ( NK, LAK, CTL, Macrophage), cytokine activities ( 1L-1, 1L-2, 1L-6, TNF), proliferation of lymphocytes and chemosensitivity of tumor cells, and compared it with radioactive isotope assay. The results showed that the MTT assay may be used to test the cellular cytotoxicity, cytokine ac-tivity, proliferation of lymphocytes and chemosensitivity of tumor cells. We think it is a simple, rapid, economic and safety method.

Objective To provide anatomical basis for reconstruction thumb of free bifoltaed bone flap pedicled with the dorsal carpal branch of ulnar artery. Methods After red latex was infused into the arteries of 35 sides of adult cadaveric upper limbs, the origin, course, branches, diameters, skin branches and periosteal branches of dorsal carpal branch of ulnar artery were observed, to initate operation experiment of reconstruction thumb on 1 sides. Results The dorsal carpal branch begins with ulnar artery (4.0?1.0)cm above the pisiform with diameter of (1.3?0.5)mm, its pedicle ranges(1.2?0.5)cm and branches off into ascending and descending branches. There were outer diameter range(0.8?0.3)mm and (1.1?0.2)mm. Skin branches of dorsal carpal branch of ulnar artery nourinshed the forearm ulnar side, carpal and dorso-ulnar aspect of mid-hand, periosteal branches of dorsal carpal branch of ulnar artery nourished the anterior internus side of the ulnar and the fifth metacarpal bone. Conclusion The free bifoltaed bone flap pedicled with the dorsal carpal branch of ulnar artery is available to reconstruction the thumb.
