Objective: To investigate the rate of post-stroke depression and psychosocial factors related to it, and to provide the direction and the basis for clinical nursing. Methods: 69 patients with stroke were assessed by Zung Self-rating Depression Scale and Type A Behavior Pattern Scale. Their sex, age, behavior type, marital condition, level of education, supportor of medical expenses were collected and analysed statistically. Results: The rate of post-stroke depression was 59.42%, and the rate in type A behavior group was higher than that in the other behavior groups(P

AIM: To investigate the role of p38 protein kinase in the activation of rat alveolar macrophages(AMs) induced by lipopolysaccharide(LPS). METHODS: Nuclear protein was extracted, p38 protein kinase in nuclear extracts was analyzed by Western blot. The concentrations of TNF-? and IL-8 in supernatant were measured by radioimmunoassay. RESULTS: The concentrations of TNF-?, IL-8 in supernatant and p38 protein kinase in nuclear extracts were increased significantly induced by LPS and blocked by SB203580, a selective inhibitor of p38 protein kinase. CONCLUSION: The inductoin of TNF-? and IL-8 in alveolar macrophages by LPS may be mediated through the activation of p38 protein kinase.

Objective To investigate the changes of visual evoked potentials (VEP) in patients with Parkinson’s disease (PD). Methods Pattern reversal checkerboard VEP and the unified Parkinson’s disease rating scale (UPDRS) were evaluated in 69 patients with PD and 61 healthy controls. The 69 patients and 61 healthy controls were divided into an aged group (≥60 years old) and a non aged group (0.05). Conclusions VEP reflected objectively the patients’ electrophysical changes of the visual pathway due to dopamine changes and it may be helpful in PD diagnosis.

Objective To establish a fluorescent quantitative polymerase chain reaction method for quantifying the ICP4 gene expression of herpes simplex virus type 2(HSV2).Methods According to the HSV2 ICP4 gene sequence,we designed and synthesized PCR primer.The purified PCR product was sequenced after connecting with pMD-18 T plasmid.According to the sequence assay results,the primer and probe of fluorescent quantitative PCR was designed and synthesized.Standard recombinant plasmid extracted from the positive bacteriumclone was used as standard substance.The plasmid as standard substance was diluted for 10 times,then PCR reaction proceeded.The sensitivity and dependability of the real-time fluorescent quantitative PCR were analyzed.Results The sequence result indicated that there was non-sense mutation of A-G and T-C.And the detection sensitivity was 101 copy.The Ct value were 14.275土0.137,17.988?0.162,22.081土0.259,25.957土0.345,29.565?0.203,33.269土0.287,37.737?0.698,respectively with 107~ 101 copies/?l.The coefficient of variability were 0.965%,0.902%,1.174%,1.329%,0.686%,0.862% and1.851%,respectively.There was a good linear function in statistics between the Ct value and the concentration gradient of standard plasmid DNA specimen.The coefficient of regression was 0.998.Conclusion The method of quantification of ICP4 gene of HSV2 with real-time fluorescent quantitative PCR is successfully established,and the method has good sensitivity and dependability,which can be used to quantitative detecting HSV2 ICP4.

AIM: To evaluate effects of Pinaverium Bromide on different segments and layers of colonic smooth muscle in wrap restraint stress (WRS) rats and explore its possible therapeutic mechanism on different types of irritable bowel syndrome (IBS). METHODS: Adult SD rats were randomly divided into model group (wrap restraint stress group) and control group. Colonic smooth muscle strips were made from different segments and layers in two groups. The spontaneous contraction activities of colonic longitudinal/circular muscle (LM/CM) strips of rats were observed with organ bath system before and after addition of series concentrations of pinaverium. RESULTS: Pinaverium Bromide caused concentration-dependent inhibition of colonic smooth muscle, the inhibitory effect of pinaverium in model group was significantly stronger than that in control group(proximal colon: 28.54±4.82 vs 7.48±1.65,21.75±1.00 vs 12.56±3.15; distal colon: 15.71±5.27 vs 3.89±1.16, 20.16±3.16 vs 7.56±1.96 )(P<0.05). Compared with that of distal colon, inhibitory effect of pinaverium was significantly higher of proximal colon (P<0.05). For the inhibition of pinaverium, there was no significant difference between LM and CM strips in the same intestinal segments (P>0.05). CONCLUSION: Effects of Pinaverium Bromide on different colonic muscle layers and segments in WRS rats is probably related with its therapeutic mechanism on different types of IBS.

Objective To evaluate the reliability and validity of the Chinese-version Successful Aging Inventory (C-SAI).Methods The C-SAI was translated according to the Brislin translation model,and its reliability and validity was tested in 181 old adults.Results The content validity index for the scale (S-CVI/Ave) was 0.975.Five factors were extracted by principal components analysis which contributed 58.035％ to the variance.The Cronbach α and split-half reliability was respectively 0.832 and 0.871 for the total scale.Conclusions The C-SAI has good psychometric quality and can be used as a measurement tool for the successful aging.

Objective To investigate the relationship between the efficacy of autologous epidermal grafting and the levels of epidermal cytokines in vitiligo. Methods A total of 57 patients with stable vitiligo receiving autologous epidermal grafting were included in this study. Before grafting, 17 patients were irradiated with narrow-band UVB on vitiliginous sites. Suction blister fluid was collected from the recipient site (vitiligous lesions) and donor site (normal skin) in these patients (including the 17 patients irradiated with NB-UVB). ELISA was used to detect the levels of endothelin-1 (ET-1 ) and stem cell factors (SCF) in suction blister fluid. Clinical efficacy was evaluated through a 3-month follow-up. Resttlts Among these 57 patients, 45 successfully responded to autologous epidermal grafting. In these 45 patients, the levels of ET-1 and SCF in vitiligous lesions were 728.97±286.12 ng/L and 329.97±114.13 ng/L respectively, significantly higher than those in nomal skin (503.16±251.44 ng/L, 224.73±107.91 ng/L, t = 5.443, 5.897, respectively, both P < 0.05 ). In those who responded poorly, significant difference was also observed in the level of SCF between the normal skin and vitiligous lesions (309.00±163.89 ng/L vs 204.22±83.25 ng/L, t = 3.03, P < 0.05), but not in the level of ET-1. Increased level of ET-1 was observed in both vitiligous lesions and normal skin of patients who responded well compared to those who responded poorly, while no difference was noticed in the level of SCF between these two groups of patients. The level of ET-1 was statistically higher in vitiligous lesions in patients exposed to NB-UVB than in those without exposure (t = 1.44, P > 0.05). In those patients who responded successfully, the level of ET-1 was lower in the 15 patients exposed to NB-UVB compared to the other 30 patients without exposure (548.48±230.22 ng/L vs 794.60±278.72 ng/L, P<0.05); no significant difference in the level of SCF was noted. Conclusions ET-1 and SCF may both play important roles in the repigmentation of vitiligo, with ET-1 exerting a more important role.

Rat models with common peroneal nerve injury were treated with modified Decoction for Invigorating Yang orally to observe its effect on the nervous functional recovery after peripheral nerve injury. The result showed that the motor nerve conduction velocity of the drug group during the whole observation period was higher than that of the control group (p

Objective To analyse the possible risk factors associated with the progression of vitiligo.Methods A questionnaire survey was carried out to collect the clinical data on 1088 patients with vitiligo.The relationship between possible inducements to the progression of vitiligo and lesion area was statistically analyzed in patients with the same clinical course of vitiligo. Paired t test was performed to compare the mean area index of involvement between patients with inducements and those without Results A significant difference was observed in the mean area index of involvement between patients with isomorphic response and those without (t = 6.770, P ＜ 0.01 ) as well as between patients negatively affected by psychiatric factors and those unaffected (t = 6.704, P ＜ 0.01 ), but not between patients with family history and those without (t = 1.499,P ＞ 0.05). Conclusion A rapid progression of vitiligo is more likely to be observed in patients negatively affected by psychiatric factors and patients with isomorphic response.
