Objective To investigate the risk factors and effective nursing for patients with benign prostatic hyperplasia(BPH)within 3 days after operation.Methods The risk factors for restlessness of patients with BPH in 2006 were analyzed and the nursing points were summarized.Results Age of patients,surgical style and sleeping time before the operation were evidently related to the incidence of restlessness.Conclusion Strengthening of psychological nursing,appropriate surgical style and insurance of abundant sleeping time before operation could reduce the incidence of restlessness of patients after operation.

Objective To investigate the effect of ketamine on the synaptic long-term potentiation(LTP) in the CA1 area of rat hippocampal slices,and to elucidate the mechanisms underlying the effect of ketamine on memory.Methods Hippocampal slices(400 ?m thick) were obtained from the brains of male Sprague-Dawley rats(2 months old) weighing 200-250 g that were decapitated.The slices were incubated in artificial cerebrospinal fluid(ACSF) at room temperature for at least 120 min before use.Forty-nine slices were randomly divided into 7 groups(n=7):control group,ketamine 1,5,10,30,50 and 100 ?mol?L-1 groups.All the slices in each group were perfused with ACSF,ketamine 1,5,10,30,50 or 100 ?mol?L-1,respectively.The slices in each group were performed to record evoked population spikes(PS) using extracellular microelectrode recording technique.Another forty-nine slices were randomly divided into 7 groups(n=7):LTP group,ketamine-LTP 1,5,10,30,50 and 100 ?mol?L-1 groups.All the slices in each group were perfused with ACSF,ketamine 1,5,10,30,50 or 100 ?mol?L-1,respectively.PSs were recorded for at least 30 min before LTP in each group.For LTP induction,high-frequency stimulation(HFS) conditioning pulses(100 Hz?s-1) were applied to the Schaffer collateral-commissural pathway of hippocampus using a bipolar stimulating electrode.The changes in PS amplitude after HFS were analyzed in each group.Results The PS amplitude of the rat hippocampal slices in ketamine 1,5,and 10 ?mol?L-1 groups had no significant difference compared with control group.The PS amplitude in ketamine 30,50 and 100 ?mol?L-1 groups decreased compared with control group(P

Objective To investigate the injury of podocyte and its association with proteinuria in IgA nephropathy (IgAN). Method Thirty-five patients of IgA nephropathy with proteinuria more than 1.0 g/24 h were enrolled in the study, and eight cases of renal harmatomaeetomy or renal cancinomaectomy were as controls. Cell cycle regulatory proteins (p21, p27), podocyte-associated molecules (integrin-β1, nephrin, α-actinin 4, nestin), foot process width (FPW) and the amount of podocyte were examined by immunohistochemistry and real-time PCR, respectively. Patients were divided into two groups according to podocyte number per volume (Nv): podocytopenia group (n=15, Nv<52.49×106/μm3) and normal number group (n=20, Nv≥52.49× 106/μm3). Proteinuria was followed up for eighteen months. Results Compared with the controls, podocyte p21 was re-expressed, while the expression of p27 was decreased (0.71±0.12 vs 0.91±0.07, P<0.05) in IgAN. The nestin protein level was markedly decreased in IgAN (13.4%± 0.04% vs 17.6%±0.04%, P<0.05). The mRNA expression of integrin-β1 was significantly increased (12.54±5.20 vs 1.02±0.30, P<0.05), while the amount of nephrin, α-actinin4 remained unchanged. Effacement of foot processes and podocyte detachment from the glomerulax basement membrane were observed in some cases. Nv was significantly less than that of controls (161.27± 225.92 vs 323.22±138.12, P<0.05), which was associated with the Lee's grade of IgA nephropathy. The integrin-β1 mRNA expression and Nv were negatively correlated with baseline proteinuria by univariate analysis (r=-0.840, P=0.034; r =-0.4483, P=0.014, respectively). Proteinuria in podocytopenia group was decreased more slowly than that in normal number group. Conclusions Podocyte injury exsists in IgAN with proteinuria, which manifests alterations in cell cycle regulatory protein and some podocyte-associated molecules, as well as foot process effacement and loss of pedocyte. Podocyte injury may be involved in proteinuria by affecting the progression of proteinuria in IgAN.

Objective To investigate the effect of cluster needling at scalp points plus gavage of modified Buyang Huanwu decoction on NSC differentiation in rats with ischemic stroke of qi deficiency and blood stasis type.Methods A model of qi deficiency and blood stasis syndrome was made using healthy rats. Dil dye was given for pre-labelling after the success of model making. The rats were randomized into groups A, B, C, D, E and F. Group F consisted of 4 rats and each of the other groups, of 12 rats. A rat model of ischemic stroke of qi deficiency and blood stasis type was made by MCAO at 48 hrs after pre-labelling. After the success of model making, group A was the model group, group B was treated by cluster needling at scalp points, group C was treated by an oral gavage of Buyang Huanwu decoction, group D was treated by an oral gavage of modified Buyang Huanwu decoction, group E was treated by cluster needling at scalp points plus an oral gavage of modified Buyang Huanwu decoction and group F was the sham operation group. The rats were sacrificed at various time points respectively and the materials were taken. By nerve function assessment, double immunofluorescence staining and laser scanning confocal microscopy, a comparative study was conducted to investigate the effects of different treatments on NSC differentiation.Results There was a statistically significant difference in the nerve function score between group B, C, D, E or F and group A after one week of treatment (P<0.01), between group B or E and group A after two weeks of treatment (P<0.05,P<0.01) and between group E and group C or D after one and two weeks of treatment (P<0.01,P<0.05). After one and two weeks of treatment, there were statistically significant differences in Brdu﹢/NeuN﹢ cell count, Brdu﹢/GFAP﹢ cell count, Dil﹢/Brdu﹢NeuN﹢ cell count and Dil﹢/Brdu﹢/GFAP﹢ cell count between group B, C, D or E and group A (P<0.01), between group D or E and group B or C (P<0.01) and between groups E and D (P<0.01).Conclusions Various treatments have a promoting effect on nerve stem cell differentiation in the rats. Of various treatments, cluster needling at scalp points plus gavage of modified Buyang Huanwu decoction has the best therapeutic effect.

Objective To observe the brain tissue recovery in patients with bilateral chronic subdural hematomas after drilling and drainage treatments. Methods The clinical data of 143 patients with bilateral chronic subdural hematoma performed drilling and drainage in our hospital from January 2011 to December 2016 were collected, including gender, age, the longest and widest diameters of the skull and the longest diameter of the initial hematoma, the widest diameter of the initial hematoma, the widest diameter of the postoperative hematoma, and other clinical information. The postoperative absorption of hematoma and recovery of brain tissues were analyzed. Results In these 143 BCSDH patients, 119 were male and 24 were male; the mean age of these patients was (67.7 ±1.1) years (21-92 years old), and the mean age of male patients was (67.2 ±1.2) years and the mean age of female patients was (70.2±2.5) years. The longest diameters of the skull was 134.8 mm-177.8 mm (averaged 155.5 mm± 0.7 mm) and the widest diameters of the skull was 113.5 mm-147.0 mm (averaged 131.7 mm±0.5 mm). The longest diameters of the left and right initial hematomas were (113.4±2.5) mm and (117.6±2.1) mm,and the widest diameters of the left and right initial hematomas were (15.8±0.5) mm and (17.2±0.8) mm. There was no significant difference in the recovery rate of brain tissues between patients with different gender, age or lesion sides (P<0.05). The recovery rate of brain tissues was positively correlated with the longest and widest diameters of initial hematomas (r=0.143, P=0.018; r=0.181, P=0.002). A total of 58 patients (40.6％) presented a single-side distance<10 mm from the brain tissue to the inner edge of the skull within one week after surgery, and a total of 48 patients (33.6％) showed both sides brain recovery to<10 mm. Conclusions Drilling and drainage are the first line treatment for patients with bilateral chronic subdural hematoma and contribute to the re-location of brain tissues. The rate of brain tissue recovery is positively correlated with the size of primary hematoma.
