ObjectiveTo explore the effect of the intervention by the family members on the rehabilitation of dysfunction of the patients with hemiplegia after acute cerebral infarction.MethodsSixty patients of hemiplegia caused by acute cerebral infarction were randomly divided into two groups, observing group and control group(30 patients for eaeh group).Patients in the observing group received family members' intervention in addition to the regular drug and rehabilitation treatment,which was used in control group only.The change of scores of Fugl-Meyer Assessment(FMA) and Modified Barthel Index(MBI) before and after treatment was evaluated respectively.ResultsThe scores of FMA and MBI in both groups rose very significantly eight weeks after treatment(P<0.001). But the scores of the obersevertion group were higher than that of the control group(P<0.05).ConclusionProper intervention by the family members plays an important role in enhancing the rehabilitation of acute cerebral infarction dysfunction and developing the patiennts' ability to take care of themselves in daily life.

Ex-vivo liver resection and liver autotransplantation offers a chance to cure extensive regional liver diseases which are otherwise deemed untreatable in selected cases. A 33-year-old male patient with advanced alveolar echinococcosis (AE) which invaded the right lobes and adjacent retrohepatic inferior vena cava, while the left lobes were free from lesion and had proliferated to over 1200 ml in size except for a 1 cm × 1 cm solid lesion in the segment Ⅳ. No extrahepatic metastases were found in this patient. A lesion with a size of 4300 ml and other small lesions in the right lobes were removed extracorporeally,and the retrohepatic vena cava was repaired, then the remaining AE-free left lobes (more than 700 ml in size) and the retrohepatic inferior vena cava were re-implanted in situ. A temporary end-to-end cavo-caval shunt with interposition of a blood vessel prosthesis and end-to-side portocaval shunt were established to keep the blood flow during the four-hour anhepatic phase. The patient was followed up for six months, and he had no signs of residual liver disease with good hepatic function.

Objective:To compare the tropism of different adeno-associated virus (AAV) serotypes in retinal cells.Methods:The plasmids pFastBacDual-inCap and pFastBacDual-ITR-CMV-EGFP were constructed for AAV packaging with the baculovirus expression system.Recombinant adeno-associated virus type 2(rAAV2), 6, 8 and 9 serotypes were packaged, and the infectivity of rAAV was evaluated by infecting HEK293T cells at multiplicity of infection(MOI)2000.Twenty-five C57BL/6 mice were divided into five groups, with five mice per group.In the three experimental groups, both eyes of each mouse were injected 1 μl rAAV intravitreally, and 1 μl phosphate buffered saline (PBS) for the eyes of the control group.Two weeks after injection, the retinal tissues were collected for preparing flat mounts and cryosections.Enhanced green fluorescent protein (EGFP) gene expression was observed via fluorescence microscopy and laser scanning confocal microscopy.The study protocol was approved by the Ethics Committee of Suzhou Institute of Biomedical Engineering and Technology.Results:The infection efficiency of the recombinant virus to HEK293T cells was rAAV2>rAAV6>rAAV8>rAAV9, and the transduction efficiency was 39.5%, 18.4%, 8.7% and 4.6%, respectively.In mouse retinal transduction, rAAV2 and rAAV6 were highly expressed in the ganglion cells, and rAAV8 and rAAV9 were highly expressed in the retinal pigment epithelium (RPE) and photoreceptor cells.rAAV2-mediated EGFP expression in retinas was stable within three months after injection.Conclusions:Different rAAV serotypes have varying tropism and transduction efficiencies in retinal cells through intravitreal injection, rAAV2 has a high transduction efficiency and it can be stably expressed in retinas within three months after injection.
