Objective To compare the surgical effects of transurethal enucleation of prostate (TUEP)with transurethal resection of prostate (TURP) by a retrospective analysis of clinical data.Methods The patients in this study were divided into the groups of TUEP (enrolled in 2010 and 2011,n =77) and TURP (enrolled in 2009,n =27) with prostate larger than 60 g and smaller than 60 g respectively.Comparisons were made between the two groups in operation time,blood loss volume and weight of resected prostate.Results In the group of patients with prostate larger than 60 g,there was no significant difference in prostate weight ((88.5 ± 9.2) g vs.(107.0 ± 15.30) g,P =0.255),operation time ((91.5 ± 8.8) min vs.(118.3 ± 20.2)min,P =0.083),and weight of resected prostate ((48.0 ± 4.6) g vs.(58.4 ± 5.4) g,P =0.32) between the TUEP (53 patients) and the TURP (12 patients) groups.There was significant difference in blood loss ((110.0 ± 16.4) ml vs.(193.3 ± 22.3) ml,P =0.011) between the two groups.In the group of patients with prostate smaller than 60 g,there was no significant difference in prostate weight ((43.1 ± 3.2) g vs.(36.8 ± 3.4) g,P =0.072),operation time ((62.7 ±6.8) min vs.(69.3 ±6.2) min,P =0.431),blood loss ((56 ± 5) ml vs.(110±20) ml,P=0.082),and weight of resected prostate ((26.3 ±2.4) g vs.(23.6 ±2.1) g,P =0.291) between the TUEP (24 patients) and the TURP (15 patients) groups.Conclusion Compared with TURP,TUEP has the advantages of less blood loss in the treatment of patients with prostate larger than 60 g.With the improvement of surgeon' s experience and development of operation techniques,TURP will be replaced by TUEP.In the treatment of patients with prostate smaller than 60 g,the operation modality can be chosen by the surgeon based on his experience and proficiency.

Objective To study wether dezocine (DZ) can attenuate neuropathic pain in rats and to investigate its mechanism.Methods Neuropathic pain was induced by tight ligation of the left L5 spinal nerve of the male SD rats. 24 Spinal nerve ligation (SNL) model rats were randomly divided into three groups:the first group (saline group, n=8), rats were given intraperitoneal injection of 1ml of saline 14 days after SNL surgery; the second group (dezocine group, n=8), rats were given intraperitoneal injection of 5mg/kg of dezocine in 1ml saline 14 days after SNL surgery;the third group (morphine group,n=8),rats were given intraperitoneal injection of 5 mg/kg of morphine 14 days after SNL surgery. Results Intraperitoneal injection dezocine and morphine had significant analgesic effect in neuropathic pain rats. This analgesic effect lasted for 4-6 hours.Continuous injection of morphine for 3 days produced significant tolerance, while continuous injection of dezocine for 7 days still had significant analgesic effect on neuropathic pain. Conclusion Intraperitoneal injection of dezocine and morphine can attenuate SNL neuropathic pain, continuous injection of morphine for 3 days can produce significant tolerance, while continuous injection of dezocine for 7 days still has significant analgesic effect on neuropathic pain.

The “vertical tongue”method was used in speech training for 12 patients with functional speech disorder of consonant /L/.Af-ter treatment,the average vocal intilligibility of the 12 patients increased from 86.3% to 98.9%(P <0.05)./L/consonant average intelligi-bility increased from 42.9% to 85.2%(P <0.05).

Objective: To investigate the mechanism responsible for homoharringtonine (HHT), which contributes to imatinib (IM) sensitivity in the chronic myeloid leukemia (CML) cell line. Methods:We established cell lines from a patient with CML at the time of first diagnosis and relapse phase, and designated the cell lines as NPHA1 and NPHA2, respectively. Stable underexpressed EphB4 cells (NPHA2-EphB4-sh) were obtained. Leukemia cell lines were incubated with HHT. The activated signal proteins in cells were tested by Western blot. Results:EphB4 was overexpressed in IM-resistant NPHA2 compared with the NPHA1 cell line. However, the expression of EphB4 mRNA and protein were significantly decreased in knockdown NPHA2-EphB4-sh cells compared with the NPHA2 and NPHA1 (P<0.001) cell lines. NPHA2-EphB4-sh cells were sensitive to IM (IC50:0.93 mg/L), and NPHA2 showed IM re-sistance (IC50 : 5.45 mg/L) (P<0.001). However, co-stimulation with HHT+IM decreased IC50 of NPHA2 cells to 1.17 mg/L (P<0.001). Meanwhile, phospho-Rac1/cdc42 was significantly increased in NPHA2 cells compared with NPHA2-EphB4-sh (P<0.001). HHT blocked the expression of EphB4/RhoA. Conclusion: The overexpression of EphB4 contributed to IM resistance in CML line cells. EphB4/RhoA may be a new marker of IM resistance. HHT with IM yielded more treatment advantages than IM alone by blocking EphB4/RhoA pathways.

Objective To establish the in vitro biofilm model of Laribacter hongkongensis(LH),to analyze the type Ⅰ integron related genes carried by LH and to investigate the mechanism of LH resistance to quinolones.Methods The biofilm forming abilities of LH clinical isolates were determined by Giemsa staining qualitative method and by crystal violet staining semi-quantitative method.The sensitivity of LH to norfloxacin,ofloxacin,levofloxacin,ciprofloxacin and lomefloxacin in both planktonic and biofilm conditions were dectermined by broth microdilution susceptibility tests.Type I integron related genes carried in 18 LH strains resistant to quinolone were detected by PCR amplification method.Results The detection results by Giemsa staining demonstrated that 36 strains in 55 LH clinical isolates formed visible biofilm,and the biofilm formation rate was 65.4%(36/55).In the biofilm forming ability detected by crystal violet staining semi-quantitative method,OD560≤0.15 was in 8 strains of LH,0.150.20 in 7 strains respectively.The levels of minimal biofilm inhibitory concentration in norfloxacin,ofloxacin,levofloxacin,ciprofloxacin and lomefloxacin to LH were respectively higher than the minimal inhibitory concentration(MIC) in the corresponding floating bacteria(P<0.05).Among 55 strains of LH,18 strains were resistant to quinolones,the resistance rate was 32.7%,and the type I integron in 18 strains of LH carried the drug resistant genes,these drug resistant genes played the drug resistance role in corresponding bacterial strains.Conclusion Drug resistance gene formation and widespread of LH may be associated with type I integron.

The research on regulation rules of traditional Chinese medicine (TCM) syndrome was the core of TCM syndrome information. It was thought that the constitution identification which provided the technology for evaluating health status was one of the bases in drawing the curve of conditional standard of syndrome. It was fitted and analyzed by the curve of conditional evolution of syndrome through establishing the curve of conditional standard of TCM constitution theory. It was the key technology of realizing the dynamical evaluation of TCM clinical effect.

Objective To investigate the effect of rapid eye movement (REM) sleep deprivation on spatial memory and hippocampal cellular prion protein (PrPC) expression and to explore the underlying mechanism of cognitive impairment induced by sleep deprivation.Methods Adult Sprague-Dawley rats were sorted by weight,randomly divided into three groups:the cage control (CC) group,the tank control (TC) group,and the sleep deprivation (SD) group.Rats were deprived of REM sleep for 72 h using the modified multiple platform method.The Morris water maze task was used to assess hippocampal-dependent spatial memory.After sleep deprivation,the rats were sacrificed and their brain tissue was analyzed for PrPC protein expression via Western blotting.Hippocampal neuron axon elongation was examined as well after lentivector-mediated RNA interference (RNAi) of PrPC in primary cultured rat hippocampal neurons.Results REM sleep deprivation for 72 h resulted in spatial memory impairment.The number of times of rats passing through the platform was decreased significantly in the SD group (3.17 ±0.95) compared with the CC (7.17 ±0.95) and TC (6.50 ±0.62) groups (Z =2.026 6,Z =2.026 6,P ＜0.05),the mean value of proximity to the platform (mm) was greater for rats of the SD group (711.74 ± 33.99) compared to those of theCC (592.32±31.31) andTC (580.86±11.36) groups (Z=-2.001 6,Z=-2.4820,P ＜ 0.05).REM sleep deprivation for 72 h resulted in reduced PrPC level in the hippocampus (0.33 ± 0.10) compared with the CC (1.01 ±0.33) and TC (0.96 ±0.27) groups (Z=2.152 9,Z=2.152 9,P ＜ 0.05).In primary cultured hippocampal neurons,axon elongation(μm) was inhibited 7 days in infected neurons (326.28 ± 12.53) compared with normal (555.00 ±30.43) or negative control (558.70 ±23.10) cells (Z =4.768 4,Z =4.877 0,P ＜ 0.05).Conclusion These findings suggest that PrPC-mediated hippocampal neuron axon elongation inhibition is probably involved in spatial memory impairment induced by sleep deprivation in rats.
