Objective To investigate the factors related to outcome (recovery of motor, activities of daily living, and balance) of stroke patients. Methods 67 stroke patients with hemiplegia were evaluated with the Ueda Classfication of upper and lower limbs function, Functional Independence Measure (FIM), Berg balance scale (BBS) before and after treatment. The scores of all the assessment were as the dependent variable respectively, and regression analyzed with the factors possiblely related to the outcome. Results The positive factors for lower limbs function included rehabilitation intervention, time of rehabilitation, and hypercholesterolemia; while the negative factors were body mass index (BMI), and damage of superficial sensibility. The positive factors for upper limbs function were rehabilitation intervention and time of rehabilitation; while the negative factors were BMI, dysphagia, damage of superficial sensibility, and frequency of attack. The positive factors for hand function were rehabilitation interventions and interval from diagnosis to rehabilitation, while the negative factors were the muscle tension, incontinence, and frequency of attack. The positive factors for FIM were the rehabilitation intervention, while the negative factors were BMI, incontinence, hypercholesterolemia, gender and residence status. The positive factors for BBS were the rehabilitation intervention, while the negative factors were BMI, frequency of attack, and hyperglycemia. Conclusion Rehabilitation promotes the recovery of stroke patients, but the BMI may block it.

Objective To investigate the clinical features and effective treatment of patients with severe type A H1N1 flu in Wenzhou. Methods The clinical data of 42 hospitalized patients with severe type A H1N1 flu were analyzed and the clinical features were summarized. Results A total of 42 patients with severe type A H1N1 flu all began with fever and cough. The symptoms of expectoration, pharyngalgia, chilly accounted for 92. 9%, 90. 5% and 42. 9%, respectively. The peripheral leucocyte counts were normal or reduced. C-reactive protein and erythrocyte sedimentation rate levels both increased in 30 patients (71.4%). About 95.2% (40/42) patients had changes of pulmonary imaging. All of the patients were treated with oseltamivir and effective antibiotic drugs as well as symptomatic management. No patients was treated with glucocorticoid. The patients with underlying diseases were given proper treatment. Three cases were treated with antifungal therapy and 3 pregnant patients were timely terminated of pregnancy. Conclusions Severe type A H1N1 flu progresses rapidly and the lower respiratory tract is involved soon after onset. Therefore, the patient should be diagnosed early and treated promptly after presenting fever, which will lead to good prognosis.

Soil water is one of the most important components in hydrological cycle. The stable hydrogen and oxygen isotopes in soil water have been increasingly used in the ecological, environment and hydrological research. In view of different techniques for extracting soil water, there is significant difference in theδD andδ18 O composition. This paper presents a method for analyzing hydrogen and oxygen isotopes in soil water by using elemental analyzer and isotope ratio mass spectrometry with accelerated solvent extraction for sample pretreatment. The conditions are: extraction solvent: dichloromethane, temperature: 100 ℃, pressure of 10. 3 MPa, static time:10 min. The samples were extracted three times, and with cycle values of four, four and three, respectively. Comparing with the added water, the deuterium and oxygen isotope values in the extracted soil water enrich 2. 12‰-4. 58‰ and 0. 17‰-0. 93‰, respectively. The reproducibility of replicate extractions of soil water is around ±0. 89‰ for δD and ±0. 37‰ for δ18 O.

This paper is to report the exploration of the activation of Rho/ROCK signal pathway in 5-HT-induced proliferation of rat pulmonary artery smooth muscle cells (PASMCs) and the inhibitory effect of m-Nis on this pathway. PASMCs were cultured with the explant technique. MTT assay was used to explore the proliferation of PASMCs after 5-HT treated for different time and the intervening effect of m-Nis. RT-PCR and Western blot were used respectively to explore the mRNA expression of RhoA, ROCK1 and the protein expression of p-MYPT1 in 5-HT-treated PASMCs and intervening effect of m-Nis. The results of MTT assay suggested that 5-HT (1 µmol · L(-1)) treatment for 12-72 h significantly induced the proliferation of rat PASMCs (P<0.05 or P < 0.01), which were inhibited by m-Nis (1 x 10(-5), 1 x 10(-6), l x 10(-7), 1 x10(-8) mol · L(-1)) in dose-dependent manners (P < 0.05 or P < 0.01). Similarly, the mRNA expression of RhoA, ROCK1 and the protein expression of p-MYPT1 were also inhibited by m-Nis in different degrees (P < 0.05 or P < 0.01). Thus, the results of this study suggested that Rho/ROCK pathway played an important role in 5-HT-induced proliferation of rat PASMCs, m-Nis inhibited 5-HT-induced proliferation obviously, which may be related to the blockage of Rho/ROCK signal pathway.

OBJECTIVETo investigate the correlation of perihematomal free radical level and neuronal apoptosis following the intracerebral hemorrhage (ICH).

METHODSAnimals were randomly divided into 4 groups: sham operation group, model group, 1 mg/kg edaravone group, and 3 mg/kg edaravone group. Each group was then divided into seven subgroups, in which the rats were correspondingly killed at 6 h, 12 h, 24 h, 48 h, 72 h, 7 d or 14 d (n = 1 in each subgroup of the sham group, and n = 6 in each subgroup of the other 3 groups). By Horseley-Clarke technique, autoblood (80 microL) were administered into the left caudate putamen of SD rats in a double administration-withdrawal way. Rats in the sham group were needled in but not administered with autoblood. The ICH model was then evaluated by Bederson's scale. Around the hematoma, the levels of malonaldehyde (MDA) and hydroxyl radical were tested by spectrophotometer, and the process of apoptosis was tested by terminal deoxynucleotidyltransferase-mediated dUTP-biotin nick end labeling (TUNEL) method.

RESULTS(1) ICH significantly increased the levels of MDA and hydroxyl radicals. Significant differences in MDA and hydroxyl radical contents were observed among the four groups. (2) In the sham group, a small number of TUNEL-positive cells were found. In the other three groups, the TUNEL-positive cells were observed at 6 h, increased significantly at 24 h, and reached peak level at 3 d, then fell profoundly at 7 d, but remained detectable at 14 d. (3) The positive correlation existed between apoptosis and free radical level (r = 0.2003), and existed between apoptosis and MDA content (r = 0.6563) in the brain.

CONCLUSIONPost-hemorrhagic apoptosis was related to the production of free radicals, indicating that the elevated free radicals following the ICH could induce neuron and glial cell apoptosis.

OBJECTIVETo evaluate the inhibitory effect of small interfering RNA (siRNA) targeting HBV C gene region on hepatitis B virus (HBV) in vivo.

METHODSAn animal model of HBV infection was developed hydrodynamically, and pcDNA3.1-HBV and siRNA were together injected into the tail vein of the BALB/c mice. HBsAg was analyzed by time-resolved immunofluorometric assay, HBV DNA was analyzed by fluorogenic quantitative PCR (FQ-PCR), HBV C-mRNA was detected by semi-quantitative RT-PCR, and viral specific proteins (HBsAg and HBcAg) in the mice livers were assayed using immunohistochemical staining.

RESULTSIn the mice, the siRNA effectively inhibited HBV replication and expression compared with the controls. The inhibitive effect of siRNA on HBV lasted at least 3 days.

CONCLUSIONThese results demonstrate that RNAi can substantially inhibit HBV replication and expression in vivo.
