ObjectiveTo study neural protective effect of combined medication with nimodipine and mannitol on injury of cerebral ischemia-reperfusion for screening the better medication method in acute cerebral ischemia-reperfusion. MethodsA model of cerebral ischemia-reperfusion was performed by clipping bilateral common carotid artery of rats with vago- and releasing them 3 hours later. 40 Wistar female rats within 1 month were divided into 5 groups randomly with 8 rats each: model group (no use of medicine), nimodipine group(0.2mg/kg), mannitol group(0.5g/kg), nimodipine and mannitol group, sham-operated group (no use of medicine and no clipping process). The changes of SOD and MDA in brain tissue were measured 24 hours after cerebral ischmic reperfusion in all groups. At the same time pathologic study was performed to compare the different groups.ResultsThere were significant differences between nimodipine and mannitol group and other groups in changes of SOD, MDA and pathological changes(P<0.01). Conclusions Combined medication with nimodipine and mannitol is the better way to protect brain tissue from acute cerebral ischemia-reperfusion than other way in present experiment, by synergistic action.

OBJECTIVETo investigate the characteristics, diagnosis, and treatment of ovotesticular disorder of sex development (OT-DSD).

METHODSWe retrospectively analyzed 2 cases of OT-DSD treated in our hospital. The patients were 19 and 15 years old, respectively, and both received systematic physical examination and examinations of the karyotype, sex hormone, adrenocorticotropic hormone (ACTH), color Doppler ultrasonography, urethrocystoscopy, and human chorionic gonadotropin (HCG) test. Under the laparoscope, we performed surgical gonad exploration, gonadectomy, and vulvar orthopedics. Intraoperative exploration and pathology confirmed true hermaphroditism in both cases, with sex selection as female. One underwent laparoscopic resection of the ovotestis, and the other removal of the testis with the ovarian tissue reserved.

RESULTSThe patients were followed up for 12 months postoperatively, which found no abnormality in either the vulvas or the genital glands.

CONCLUSIONSurgical exploration of the gonad is the only method for the diagnosis of OT-DSD and sex selection is the key to treatment. Laparoscopic surgical exploration of the gonad and vulvar orthopedics are the first treatment options.

This study was aimed to clone human intercellular adhesion molecule-1 (ICAM-1) gene, to transfect the constructed eukaryotic expression vector ICAM-1-GFP into CHO cells, as well as to detect ICAM-1-GFP expression in CHO cells binding with Molt-4 cells. ICAM-1 cDNA gene was amplified by RT-PCR and inserted in PMD(18)-T vector. Then ICAM-1 cDNA from pMD18-ICAM-1 vector was subcloned into eukaryotic expression vector pEGFP-C1 to construct recombinant ICAM-1-pEGFP-C1 vector. Restriction analysis and DNA sequencing were used to confirm the recombinant vector. After stable transfection of CHO-K1 cells with the recombinant vector, the expression and subcellular localization of ICAM-1-GFP were detected by RT-PCR, flow cytometry and fluorescence microscopy. The function of ICAM-1-GFP fusion protein was assessed by the binding of ICAM-1-GFP/CHO cells to Molt-4 cells. The results showed that 1622 bp full-length ICAM-1 cDNA obtained and was successfully ligated with pMD(18)-T-vector, subcloned to construct recombinant ICAM-1-pEGFP-C1 vector. Restriction analysis and DNA sequencing indicated that recombinant ICAM-1-GFP was successfully constructed and ICAM-1-GFP was expressed stably in CHO cells. ICAM-1-GFP expression was only observed in the cytoplasm of ICAM-1-GFP/CHO cells by fluorescence microscopy. The ICAM-1-GFP/CHO cells were bound to PMA-treated Molt-4 cells. The expression of MEM-148 was very weak in PMA-treated Molt-4 cells. It is concluded that the ICAM-1-GFP eukaryotic expression vector has been constructed successfully and expresses stably in CHO cells. PMA can increase the binding of Molt-4 cells to ICAM-1-GFP/CHO cells by inducing specialized form of ICAM-1 clustering.

ObjectiveTo explore the effectiveness and practicability of training technique in hemiplegia.Methods313 stroke patients with hemiplegia were divided randomly into the control group and training group, and treated with integrative training technique for hemiplegia impairment during 3 months. Locomotor recovery and the performance of activities of daily living (ADL) of patients in two groups were assessed before and after one, two and three months training respectively, using Fugl-Meyer Assessment (FMA), Functional Independence Measure (FIM) and the scale of impairment in community rehabilitation.ResultsAfter treatment, FMA, FIM and the scale of impairment in community rehabilitation of the patients in the training group improved significantly ( P<0.001), the effectiveness was better than that of the control group ( P<0.05～0.001).The scales of FMA and FIM were proportional to the scale of impairment in community rehabilitation.ConclusionThe training technique for hemiplegia has ideal rehabilitation effectiveness.

The purpose of study was to evaluate the effect of stopping use of cyclosporine A (CsA) in reversion of donor chimeras of chronic myeloid leukemia (CML) patients relapsed after transplantation. Two CML patients were transplanted with allogeneic peripheral blood stem cells, and relapsed after transplantation, their bcr/abl gene and/or ph1 chromosome showed positive, donor chimeras decreased. For these two CML patients relapsed after transplantation, the use of CsA was stopped immediately, and the patient's body temperature, skin rash, blood picture, liver function and chimeras were planed to observe carefully. The results indicated that acute graft versus host disease (aGVHD) appeared in both patients. A hundred percent (100%) of donor chimeras were then found with bcr/abl gene and/or ph1 chromosome turning to negative in both patients. In conclusion, to stop using of CsA might be effective in the treatment of some CML patients relapsed after transplantation by reversing of donor chimeras and inducing graft-versus-leukemia (GVL) effect accompanied by GVHD.
