Objective To construct a plasmid expression vector coding for the short hairpin RNA(shRNA) targeting Twist mRNA.Methods Two plasmid expression vectors coding for shRNA targeting 777 and 845 of Twist gene sequence and a control vector containing random DNA fragment were constructed.The recombinant plasmids were identified by PCR,and then transfected separately into bladder cancer cell line T24.The Twist gene silencing effect was detected by RT-PCR and Western blotting.Results The expected band of 400 bp was amplified from the plasmids coding for shRNA by PCR.By DNA sequencing,it was the same with the insertion element as with the shRNA of synthetic.Transfection of T24 cells expressing Twist gene with the shRNA plasmids resulted in inhibition of Twist mRNA and protein expressions by 90% and 86%,respectively.The shRNA1 had the most obvious effect in Two types of plasmids interference.Conclusion The plasmid expression vectors coding for shRNA targeting Twist mRNA have been constructed successfully,of which pGenesil-shRNA1 most effectively silences Twist gene in T24 cells.

Objective To explore the molecular effect and interaction among nephrin, podocin, CD2AP and ?-actinin-4. Methods Firstly, the recombinant RNA interference (RNAi) plasmid-psiRNA-hH1GFPzeo, specifically targeting to the mRNA of nephrin, podocin, CD2AP or ?-actinin-4, was respectively tansfected into the mouse podocyte clone (MPC5) to each knockdown (KD) the expression of nephrin, podocin, CD2AP or ?-actinin-4. Molecular distributions were revealed by confocal microscopy, and the mRNA and protein expressions were detected with semi-quantitative RT-PCR and Western blotting. Results (1)In podocin KD group (siPod966 and siPod54), the mRNAs of podocin and nephrin were not detected, their protein decreased 92% and 79%, 82% and 67%, respectively. The mRNA and protein level of CD2AP increased 62% and 42%, 71% and 46%, respectively, whereas ?-actinin-4 did not change. In nephrin KD group (siNep492), the mRNA expression and protein level of nephrin were not detected, CD2AP increased 35% and 48%, respectively; and whereas podocin and ?-actinin-4 did not change. In CD2AP KD group (siCda744 and siCda21), the mRNA of expression CD2AP was not detected, and its protein level decreased 92% and 83%, the mRNA and protein of nephrin decreased 60% and 48%, 76% and 72%, respectively; podocin increased 38% and 22%, 56% and 44%, respectively; whereas ?-actinin-4 did not change. In ?-actinin-4 KD group (siAct1790 and siAct319), the mRNAs expression of ?-actinin-4 and nephrin decreased 69% and 58%, 64% and 49%, respectively; their protein level decreased 81% and 55%, 71% and 64%, respectively. However, the mRNAs of podocin and CD2AP increased 50% and 34%, 45% and 28%, respectively; and their protein level increased 64% and 46%, 65% and 42%, respectively. (2) With their expression change, the distributions of nephrin, podocin and CD2AP shifted evidently from the cell membrane surface to the nucleus circumference, whereas ?-actinin-4 showed no change, which was still localized in the cytoplasm and further extended to foot processes. Conclusion (1) Nephrin might more independently play a crucial role in the slit diaphragm complex. (2) Alpha-actinin-4 might interact direcdy or indirectly with nephrin, podocin and CD2AP. (3) The relationship among these podocyte molecules might not be spontaneous, either a single-directional or bi-directional reaction. (4) The normal localization of these podocyte molecules might depend on their normal expression quantity.

Objective To explore the molecular mechanisms underlying therapeutic responses of the anti-proteinuria drugs from the view of podocyte molecule. Methods Adriamycin (ADR) nephropathy was induced by a single tail intravenous injection of adriamycin. Lisinopril, prednisone and all-trans retinoic acid (ATRA) were administered once a day to the adriamycin-induced nephrotic rats at the first day after adriamycin injection respectively. Renal tissue samples were collected at day 3, 7, 14, and 28 after adriamycin injection respectively. The distribution, mRNA expression and protein expression of nephrin, podocin, CD2AP and ?-actinin-4 were examined by indirect immunofluorescence, real-time PCR and Western blotting, respectively. The interactions among nephrin and podocin, nephrin and CD2AP, as well as the nephrin phosphorylation were detected by immunoprecipitation, respectively. Results Compared to the control rats, 24 h urinary protein of the ADR rats increased significantly at day 14 (P

Objective To observe the effects of lower limb motion control training using virtual games combined with core stability training (CST) on the lower limb motor function of hemiplegic patients after stroke.Methods Sixty hemiplegic stroke patients were divided into an observation group and a control group (n =30 in each) using a random number table.The control group was given conventional treatment and CST,while the observation group received lower limb motion control training using virtual games in addition to conventional treatment and CST.All of the patients were assessed using the Fugl-Meyer lower limb assessment (FMA),the Berg balance scale (BBS),the modified Barthel index (MBI),10 metre maximum walking speed (MWS) and functional ambulation categorization (FAC)before and after 8 weeks of treatment.Results Before the intervention there was no significant difference between the two groups in any of the measurements.After the treatment,however,the average FMA,BBS,MBI,MWS and FAC in the observation group were significantly better than those before treatment and those in the control group.Conclusions Lower limb motion control training using virtual games combined with core stability training can improve effectively the lower limb motor function of hemiplegic patients after stroke.Such a combination is worth applying in clinical practice.

Objective To analyze the effects of the mumps virus on testicular function and evaluate the value of blood testosterone in acute orchitis condition and prognosis by observing the testosterone levels of peripheral blood in the mumps orchitis patients.Methods Thirty patients with acute mumps orchitis (mumps orchitis group)and 28 patients with mumps only without any major complications (mumps group)were enrolled in the study.At the same time,we selected 20 healthy males in our hospital as healthy controls.All cases were treated by ribavirin (10mg/kg). The testosterone was tested by chemiluminescence method,in 0,7,14 days respectively.The variance analysis and LSD -t test were used to compare differences of blood testosterone in each group,and Pearson method was used to analyze the correlation of blood testosterone and testicular swelling day times,blood amylase,level of neutrophils,IL -6 and CRP.Results The testosterone of acute orchitis [(1.51 ±0.26)ng/mL]was lower than mumps group and healthy controls.The difference was significant(F =99.36,P <0.01).The level of blood testosterone was significantly increased in the treatment for 14 days (t =13.03,P <0.01),and there was no significant difference compared with healthy controls (t =1.23,P =1.23).Pearson correlation analysis found that blood testosterone levels were negatively correlated with the days of testicular swelling,the levels of IL -6 and CRP(r =0.678,P <0.01 and r =0.528,P =0.000;r =0.442,P =0.000).Conclusion This study showed that MuV infection inhibited testosterone synthesis in Leydig cells.In other words,the level of blood testosterone is related to the severity of the orchitis,which can be widely used in clinical.

Objective To investigate the MR imaging findings of acute experimental allergic encephalomyelitis(EAE) in correlation with pathology. Methods An EAE model was induced by intradermal inoculation with guinea pig CNS homogenate in 6 female Lewis rats.Another 6 rats served as control.The clinical presentation and body weight of the animals were recorded daily. Routine MRI,Gd-enhanced MRI were performed when EAE animals showed the initial symptoms. Uhrasmall superparamagnetic iron oxide(USPIO) colloid solution was also administrated intravenously and MRI was performed again after 24 hours. The brain was removed instantly after the second MR imaging. The pathological exams including HE staining,myelin sheath staining and prussian staining were performed.The imaging findings were observed in correlation with pathological results. Results The EAE rats showed decrease of body weight on the 6th to 7th day after inoculation,and the clinical symptoms appeared on the 10th to 11th day after inoculation.Routine MRI did not show any definite abnormalities.The Gd-enhanced MRI found the diffuse thickening and enhancement of brain meninges.The USPIO-enhanced MRI showedareas of low signal intensity at white matter of medulla oblongata on T2WI,and high signal intensity was observed at the corresponding area on T1 WI. Gradient T2 * WI found more foci of low signal intensity in eerebellar white matter besides the lesions in the brain stem.The range of abnormal signal intensity was larger in animal with higher clinical scores than that with lower score.There were no abnormal findings in control animaL The pathological exam found "perivascular cuff" in the brain white matter in EAE animals,some accompanied with adjacent demyelinatian. The prussian staining found blue particles within the cytoplasm of the macrophages around the lesion,which corresponded to the area of low signal intensity on T2WI.Conclusion USPIO-enhanced MRI could reveal acute EAE lesions which were not capable of being shown on routine MRI and Gd-enhanced MRI.It can image the macrophages around the lesions in vivo.USPIO is important for future research and application in MS patients.

ObjectiveTo establish a method to induce heterotopic ossification (HO) after spinal cord injury. Methods10 New Zealand White rabbits underwent a complete transection of the thoracic (T10) spinal cord. Just after transection, the right hind limb of every rabbit was immobilized with a plaster support to keep the knee in extension and the hip unrestricted. The plaster was temporarily removed once a day (six times per week) to allow the knees passively mobilized at the maximum range for 5 min. Local swelling, local skin temperature and grade of ossification of the paraplegic limbs were observed. After 5 weeks, the rabbits were sacrificed, and the quadriceps muscles of the right hind limbs were removed for the histological examination. ResultsAfter 5-week immobilization and temporary passive mobilization, HO was successfully induced in all 10 rabbits. There was local skin temperature increase and local swelling in the right hind limbs. The histological changes were similar to those observed in clinical HO. Conclusion5-week immobilization and temporary passive mobilization approach may successfully induce HO, and it may be used to study the pathogenesis of HO after spinal cord injury.
