AIMTo describe an unusual symptom of benign prostatic hyperplasia (BPH).

METHODSA patient presented to our urology clinic having experienced post-coital gross hematuria for 2 years. He had not experienced lower urinary tract symptoms (LUTS). A series of examinations were performed to determine the source of bleeding.

RESULTSThe prostate was defined as the active bleeding source responsible for the patient's post-coital hematuria. Endoscopic fulguration did not alleviate the symptom. The use of dutasteride, a dual inhibitor of 5alpha-reductase, solved the problem.

CONCLUSIONThis study reports for the first time that post-coital gross hematuria is one of the clinical presentations of BPH, which can be successfully treated with 5alpha-reductase inhibitor.

OBJECTIVETo explore the effect of Sedum sarmentosum Bunge Extract (SSBE) on severe acute pancreatitis (SAP) induced acute lung injury (ALI) model rats and their excessive inflammatory reactions.

METHODSForty-two healthy adult male Sprague-Dawley (SD) rats were randomly divided into 3 groups, the sham-operated control group (C), the SAP group (SAP), and the SSBE treated group (SSBE), 14 in each group. SAP induced ALl rat model was induced by retrograde injection of 5% sodium taurocholate (1 mL/kg) into the pancreatic duct. SSBE (100 m/kg) was administrated subcutaneously after the establishment of the SAP model. Equal dose of SSBE was injected again 12 h later. Equal volume of normal saline was administrated in the same way for rats in the C group and the SAP group. Rats were sacrificed after successful modeling and samples taken at 12 and 24 h. Pathological changes in the pancreas and the lung tissue were observed under light microscope. The ascites, serum amylase (AMS), wet/dry proportion (W/D) of the lung tissue, activities of myeloperoxidase (MPO), interleukin-1 (IL-1), IL-6, and tumor necrosis factor-alpha (TNF-alpha) were also measured.

RESULTSAscites and serum AMS activities significantly increased; MPO, IL-1, IL-6, TNF-alpha contents, and W/D ratio also significantly increased in the SAP group, when compared with the C group (P<0.05). Compared with the SAP group, those parameters were all attenuated in the SSBE group at 12 and 24 h (P<0.05, P<0.01). Pathological changes in the pancreas and the lung tissue were alleviated in the SSBE group under light microscope. The injury degree ranged between that of the C group and the SAP group.

CONCLUSIONSSBE could relieve the ALl in SAP model rats, which could be achieved through alleviating inflammation responses of SAP rats.

Objective To observe the effect of electroacupuncture combined with physical and hyperbaric therapy on activities of daily living (ADL) of cerebral infarction patients. Methods 105 cases were divided into compositive group (n=35), receiving electroacupuncture combined with physical and hyperbaric therapy; ordinary group (n=35), receiving physical and hyperbaric therapy; and control group (n= 35), not treated. They were assessed with Functional Independence Measure (FIM) and Barthel index (BI) before, 24 d and 36 d after treatment. Results The scores of FIM and BI improved the most in the compositive group (P<0.01) among these groups. Conclusion Electroacupuncture can further improve the activities of daily living of cerebral infarction patients

Objective To investigate the effects of rehabilitation on cognitive function, expression of synaptophysin and neurogranin in rats with cerebral infarction. Methods 48 male Wistar adult rats with cerebral infarction were randomly divided into model group and rehabilitation group, 24 rats in each group. The rehabilitation group received rehabilitation training from the 5th day after modeling. The cognitive ability and the expression of the synaptophysin and neurogranin were observed on the 15th day, 25th day and 35th day after modeling.Results The scores of neural function, motor ability, Y-maze test, and the expression of the synaptophysin and neurogranin were better in the rehabilitation group than in the control group (P<0.05). Conclusion The rehabilitation training can improve the neurological function, motor ability and cognitive ability of rats with cerebral infarction by increasing the positive expression of synaptophysin and neurogranin.

Streptomyces sp. A048 was cultured in a complete medium to the last stage of log phase,the hyphae were washed and collected by centrifugation. Then the hyphae were inoculated in liquid medium for chitinase production using two-step fermentation. Activity of chitinase produced by two-step fermentation was 1.1 times higher than that from one-step fermentation,and ferment cycle was for 54 hours,which was 66 hours shorter than that of one-step fermentation. The hyphae and the powder of chitin were co-immobilizated and cultured in liquid medium for 36 hours,activity of chitinase was 1.8 times higher than that from one-step fermentation,and ferment cycle was 54h shorter than that of one-step fermentation. By adding 0.4% cellulose to two-step fermentation,activity of chitinase was 18.52 U/mL that was 4 times higher than that from the control and 10 times higher than that from one-step fermentation. Two step fermentation with chitin and cellulose may be the optimal fermentation process to produce Chitinase from Streptomyces sp. A048.

Objective To analysis and determine the possibility of the Citellus undulatus infected with Yersinia pestis surviving the winter in an experimental study, and to provide scientific experimental basis for the study on the mechanism of Yersinia pestis preservation. Method In 2006,09 to 2007,04 and 2007,09 to 2008,04 in Xinjiang Wusu-Gurtu natural foci of plague, under natural conditions, the over the winter process of Citellus undulatus carrying the plague bacteria was simulated, and 178 Citellus undulatus were infected with Yersinia pestis (1×107 Bacteria/mouse) using artificial injection method. One hundred seventy-eight Citellus undulatus infected with Yersinia pestis were kept into a construction of the black (1-5 ℃) basement (2 meters under the ground) in the plague focus. In doing so, these Citellus undulatuses almost simultaneously stepped into hibernation. After waking up from hibernation in following year in April, the survived mice carrying the plague bacteria were observed. Results Sixty-eight mice survived among the 178 infected with Yersinia pestis after 6 months of hibernation (through October to the following year in April), and the remaining 110 were all dead without pulling through the hibernation period. The survival rate was 38.2% (68/178). The organ culture of Yersinia pestis of the 110 dead mice(Citellus undnlatus) were tested, 67 were negative(-), 43 positive(+), with a positive rate of 39.1%(43/110). Among the rats with positive plague bacteria, the congestive pulmonary edema and the pathological changes of the hemorrhagic inflammation of the heart, liver, spleen, kidney and injection site could be seen clearly; the plague-free mice were not found to have any pathological changes. The survived 68 mice over the winter were autopsied and observed after being fed up for 20 days. No any pathological changes were found among these mice, and culturing of Yersinia pestis of the heart, liver, spleen, lungs and the tissue of injection site of these mice were all negative (-). Conclusions Citellus undulatus can carry Yersinia pestis during hibernation, but some fail to carry the bacteria through the entire process of hibernation persistently. Yersinia pestis was negative in the survived mice at the end of hibernation. The results showed that Citellus undulatus can not carry Yersinia pestis over the winter.
