Objective: To study the adjustment amplitude of blood pressure in patients with hypertensive intracerebral hemorrhage and the guiding significance in clinical practice in monitoring the changes of cerebral hemodynamics by transcranial Doppler (TCD). Methods: The blood pressures of sixty-four hospitalized patients with intracerebral hemorrhage were monitored dynamically within 10 hours after the onset. Among them, 38 patients had intracranial hematoma puncture and tube drainage within 24 hours of hospitalization (operation group), and 18 patients had conservative treatment (conservative group). Patients were monitored with TCD at the time of hospitalization on day 1, 4, 7, and 14. Another 8 unoperated patients (antihypertensive group) were monitored with TCD before and after antihypertensive treatment, and they were compared with the TCD parameters of 26 simple hypertensive patients (control group) before and after antihypertensive treatment. Results: There was no significant difference in TCD parameters in the control group before and after antihypertensive treatment, however, the blood flow velocity of bilateral middle cerebral arteries (MCA) decreased, and the pulsatility index (PI) increased after antihypertensive treatment in the antihypertensive group. The blood pressure in patients with intracerebral hemorrhage decreased gradually during the treatment, while the blood flow velocity of bilateral MCA decreased first, and then increased. The PI values of bilateral MCA increased first, and then decreased. The blood flow velocity in the conservative group decreased within the first week of the onset. It began to increase at week two and the changes of PI values were contrary to it. The blood flow velocity of MCA increased on day 7 and PI values decreased in the operation group, and there was significant difference between the 2 groups on day 14. The blood pressure decreased more significant in the operation group than that in the conservative group, and there were significant differences in systolic pressure between the 2 groups on day 14 (P

Mitochondrial DNA (mtDNA) is a genetic effect DNA molecule of double closed loop, and is crucial for cells and their functions. Mitochondria take an active part in physiological activities of retinal pigment epithelium (RPE) cells. The oxidative stress is usually occurred in RPE for its active metabolism, which can lead to mitochondria and mtDNA dam?age. Once mitochondria and mtDNA lesions have not been repaired timely, the lesions can be accumulated, which can cause dysfunctions and damaged-structures of RPE and mitochondria, and can motivate the progression of cell apoptosis. In the end it can result in some ocular related diseases such as aged-related macular degeneration (AMD). This study reviewed the functional relationship between mtDNA and RPE, and repair and detection methods of mtDNA damage.

BACKGROUND: Since the discovery of the fact that activin can promote the survival of retinal neurocyte in chicken,the effects of activin in nervous system receives recognition. As discovered recently,hippocampal activin βA mRNA expression up-regulates in multiple brain injury animal models including ischemia and hypoxia; however,the change of activin βA mRNA expression after epilepsy is waiting for investigation.OBJECTIVE: To observe hippocampal activin βA mRNA expression at different time point after pilocarpine (PC) -induced epilepsy in mouse to explore its mechanism.DESIGN: A randomized controlled experimental study based on the experimental animals.SETTING: Department of neurology in a university affiliated hospital and the institute of neurology in a university.MATERIALS: The study was conducted in the Institute of Neurology of Huashan Hospital Affiliated to Fudan University and the Department of Pathology of Shanghai Medical College between November 2001 and July 2002. Totally 168 eight to ten-week old healthy male C57BL/6 mice with a body mass between 20 g and 25 g were obtained from Shanghai Experimental Animal Center,Chinese Academy of Science.INTERVENTIONS: 350 mg/kg(10 g/L) of PC was injected into the abdominal cavity in the mice of study group,in which 1 mg/kg of scopolamine (SC) was injected at 30 minutes before the injection of PC to antagonize its peripheral cholinergic reaction. Status epilepticus(SE) model mouse was the mouse with continuous mgoelonus or generalized seizure of rigid clonus that lasted for 1 hour after the injection of PC. Valium(4 mg/kg) was immediately injected after the modeling to terminate seizure. Same dose of Valium was injected into non-SE(NSE) mice after 1.5 hours of PC injection. Saline was used to replace PC to inject into mice of control group,and the rest disposals of control group were as same as that of study group. SE mice,NSE mice and control mice were randomly divided into six subgroups including 0hour,1 hour,3 hours,6 hours,24 hours and 48 hours subgroups according to the time point after modeling with 6 mice of each subgroup(mice of NSE group and subgroups of 0 hour time point were not included into analysis of hybridization in situ).MAIN OUTCOME MEASURES: Hippocampal activin βA mRNA expression of different time point in SE mice and NSE mice were observed by RT-PCR; the distribution of hippocampal activin βA mRNA expression at different time points in mice were observed by hybridization in situ.RESULTS: There was no significant change of hippocampal activin βA mRNA expression at different time point in mice of NSE group and control group. In SE group,activin βA mRNA(0.49 ± 0. 11) had a transient significant decrease at the beginning(0 hour),which rapidly returned to control level(0. 74 ±0. 13) at 1 hour(0.73 ±0. 12) . Activin βA mRNA continuously increased and reached (0.97 ±0. 24) at 3 hours,(1.34 ±0. 19) at 6 hours,maintained (0.98 ±0. 17) until 24 hours,and decreased to (0. 83 ± 0.09) at 48 hours afterwards,which was slightly higher than control level. Compared with control group,the increases at 3 hours,6 hours and 24hours were significant( t = 2. 668,6. 289,2. 916,P ＜ 0. 001 - 0. 05). The significant up-regulation of activin βA mRNA expression was occurred earliest in hippocampal CA2 and DG regions at 3 hours after SE,and the significant expressions also could be seen in CA3 region after 6 hours. There were expressions in only CA2 and CA3 regions after 24 hours,while there were very few positive cells in CA2 region after 48 hours.CONCLUSION: PC-induced SE could significantly up-regulate hippocampal activin βA mRNA expression,while NSE has no such up-regulative effect. The up-regulation of hippocampal activin βA mRNA expression might be an endogenous protective effect of neuron on antagonizing excitatory injury.

BACKGROUND:Infrapatelar fat pad is often partialy resected in the knee surgery, which can be used as an important source of adipose-derived mesenchymal stem cels. OBJECTIVE: To explore the strategies of isolation, culture, and identification of adipose-derived mesenchymal stem cels from the infrapatelar fat pad and to detect the expression of cel surface markers of human adipose-derived stem cels. METHODS: Infrapatelar fat pad was obtained from patients undergoing knee arthroscopy surgery, and attached cels were obtained from adipose tissue by using colagenase I. Cels were cultured in 10% low-sugar DMEM. Stem cels proliferation was detected by means of MTT and then, cel growth curve was made. The obtained cels were induced and differentiated into adipocytes and osteocytes. Expressions of cel surface markers CD29 and CD44 were detected. RESULTS AND CONCLUSION:A few of attached cels were observed after cultured 24 hours. Cels proliferated faster and exhibited spindle shape after 1 week. Cel adherence and proliferation were speeded up after subculture. Growth curve of cels exhibited that the passages 5 and 2 cels had higher reproductive activity than passage 8 cels. The obtained cels can be induced and differentiated into adipocytes and osteocytes. Results from flow cytometry showed that 96.8% passage 5 cels expressed CD29 and 97.6% expressed CD44. These findings indicate that high-purity adipose-derived mesenchymal stem cels with high reproductive ability are easy to be isolated from the infrapatelar fat pad, which may be a kind of ideal seed cels for cartilage tissue engineering.

BACKGROUND:Because insulin-like growth factor I has the ability to induce mesenchymal stem cells into chondrocytes, we hypothesized that the chondrogenic diferentiation of adipose-derived stem cels can be improvedvia insulin-like growth factor I transfection. OBJECTIVE:To investigate the influence of insulin-like growth factor I transfection on chondrogenic potential of adipose-derived stem cels in vitroand tumor necrosis factor-like weak inducer of apoptosis (TWEAK)/fibroblast growth factor-inducible 14 (Fn14) signaling pathway. METHODS:Recombinant lentivirus plasmid pLVX-IGF-I-IRES-ZsGreenl was constructed and transferred into passage 3 adipose-derived stem cels, and then these stem cels were induced to diferentiate into chondrocytes (experimental group 1). Meanwhile, the cels transfected with pLVX-IRES-ZsGreenl were taken as green fluorescent protein/adipose mesenchymal stem cel group (experimental group 2), and those with no transfection acted as control group. RESULTS AND CONCLUSION:The mRNA expression of TWEAK was reduced in the experimental group 1 as compared with the other two groups, but the mRNA expressions of insulin-like growth factor I, Col2a1 and Sox9 were up-regulated in the experimental group 1. At the same time, the protein expression of matrix metaloproteinase-3 and TWEAK were down-regulated, while the protein expression of Col2a1 was increased in the insulin-like growth factor I-transfected cels in contrast to the cels modified with pLVX-IRES-ZsGreenl or with no transfection. These findings indicate that pLVX-IGF-I-IRES-ZsGreenl transfection of adipose-derived stem cels results in a higher expression of insulin-like growth factor I, and down-regulates the expression of TWEAK mRNA and protein, which improves the diferentiation of adipose-derived mesenchymal stem cels into chondrocytes.

Objective To explore surgical methods of removing polyacrylamide hydrogel (PAHG) and the right time of repairing the deformity of breast after removing PAHG.Methods We operated with endoscopy to remove PAHG through the lower mammary areolar incision.According to injection influence,we made the dicision whether to put the silicon gel prosthesis (hereafter referred to as prosthesis) simultaneously,and to fix the porsthesis,and to rebuild the imframammary fold of breast using biological repair membrane (hereafter referred to as membrane).Results In all 46 patients,39 patients' injection and their envelope were removed entirely.7 patients left part of the envelope because of its thin and wide characters.14 of them accepted prosthesis augmentation mammaplasty simultaneously and 5 of these accepted membrane repair.4 patients received prosthesis augmentation in stage Ⅱ.All patients' incision were primary healing.The incision scars were not obvious.1 patient with breast cancer suffered breast excision; 1 patient who received prosthesis and membrane simultaneously appeared prosthesis displacement after 3 months and fixed again.1 patient who received membrane appeared hydrops in residual cavity,and the membrane was removed finally.Conclusions This method with endoscopy through mammary areolae is necessary for cleaning PAHG entirely.We can use prosthesis to repair the deformity of breast after removing PAHG,and if necessary use membrane to fix the implant and rebuild the inframammary fold of the breast.
