慢性非细菌性前列腺炎动物模型的研究进展

慢性非细菌性前列腺炎（chronic abacterial prostatitis,CAP）,是最常见的一种前列腺疾患。该病的就诊患者约占泌尿外科门诊总量的1／4。该病多发于20～40岁青壮年男性,病因尚不清楚。其I临床特点是尿频、尿急、尿痛,尿道口常有溢液,并伴有会阴、腰背、耻骨上区等部位的隐痛不适等。在CAP患者的前列腺分泌物中存在异常数量的炎性细胞,但细菌培养或其他方法均不能发现致病菌。该病容易反复发作、缠绵难愈,关联症状较多,给患者带来很大的生理痛苦及精神负担。     

圆锥铁线莲对慢性非细菌性前列腺炎的治疗作用及机制研究

本文研究圆锥铁线莲水提取物对实验性慢性非细菌性前列腺炎的治疗作用,并对其抗炎的作用机制进行初步探讨。采用苯甲酸雌二醇致去势大鼠慢性非细菌性前列腺炎模型,研究圆锥铁线莲对慢性非细菌性前列腺炎的治疗作用。酶联免疫吸附测定法(ELISA)检测血清细胞因子白细胞介素1β(IL-1β)和肿瘤坏死因子α(TNF-α)的水平,Western Blot和免疫组化法检测前列腺组织环氧酶2(COX-2)和诱导型一氧化氮合酶(i NOS)的变化,探讨圆锥铁线莲发挥抗炎作用的可能机制。研究发现苯甲酸雌二醇致去势大鼠慢性非细菌性前列腺炎模型中,圆锥铁线莲2 g/kg组可见前列腺液中白细胞数明显降低,卵磷脂小体数量明显增加;病理切片可见炎症细胞浸润和成纤维细胞增生的情况有所改善。圆锥铁线莲能明显降低苯甲酸雌二醇致去势大鼠慢性非细菌性前列腺炎模型血清中IL-1β及TNF-α的含量,减少前列腺组织中COX-2和i NOS的表达。表明圆锥铁线莲水提取物对慢性非细菌性前列腺炎具有良好的抑制作用,其作用机制可能是通过调节炎症细胞因子水平、抑制COX-2以及i NOS的表达,从而避免局部产生过量的前列腺素(PG)和一氧化氮(NO),减轻局部炎性损伤实现的。

Overexpression of lncRNA GAS5 suppresses prostatic epithelial cell proliferation by regulating COX-2 in chronic non-bacterial prostatitis

Chronic non-bacterial prostatitis (CNP) is a common urologic disease that is linked to the development of prostate cancer. Long non-coding RNA (lncRNA) GAS5 has been identified to mediate cell proliferation in prostate cancer, although its role in CNP is still unclear. Human prostate epithelial cell line RWPE-1 was induced by lipopolysaccharide (LPS) to mimic CNP model in vitro. Real-time PCR was performed to determine the expression of GAS5 and COX-2, while western blotting was used to evaluate the protein expression of COX-2. The interaction between GAS5 and COX-2 was determined using RNA pull-down and RNA immunoprecipitation (RIP). Cell proliferation was determined using MTT assay. The expression of GAS5 was decreased, while COX-2 was increased in prostatitis tissues and in LPS-induced RWPE-1 cells. The overexpression of GAS5 suppressed the protein level of COX-2, and inhibited cell proliferation of LPS-induced RWPE-1 cells and HPECs, which was rescued by the co-transfection with pcDNA-GAS5 and pcDNA-COX-2. GAS5 was confirmed to promote the ubiquitination of COX-2, and the in vivo GAS5-overexpressed CNP rat model decreased the motor scores, the volume of prostate tissues, the average number of inflammatory cells, prostatic proliferation, and COX-2 expression. Our findings revealed that overexpression of GAS5 inhibited cell proliferation via negatively regulating the expression of COX-2, thus alleviating the progression of CNP.     

雷公藤制剂对雄性布氏田鼠的不育作用

采用强制给药和自由取食2种方式,研究了雷公藤制剂对发育期成体雄性布氏田鼠不育作用,给药剂量分别为80 mg/kg、120 mg/kg和160 mg/kg.结果表明,120 mg/kg和160 mg/kg剂量使睾丸脏器系数下降,但剂量组间差异不明显(F(3,21)=2.197, F0.05=3.07,P>0.05).不同剂量能够对附睾中精子数量和活力产生显著影响(F(3,21)=17.305, F0.05=3.07,P<0.05),且随药物剂量的升高精子密度与精子活力均呈下降趋势.精子畸形率亦随药物剂量的增加而增加.80 mg/kg及其更高的剂量使附睾出现萎缩并造成睾丸组织损伤.120 mg/kg剂量可减少布氏田鼠平均胎仔数及降低繁殖率.给药后的繁殖后代未发现畸形幼仔.雷公藤制剂的最佳使用剂量介于120～160 mg/kg.自由取食与连续强制给药两种方式对雄性布氏田鼠的作用差异不显著.

The soy effect in the disease models of nonbacterial prostatitis and obstructive voiding

The goal of this study was to improve the understanding of the potential significance of dietary soy for human health by investigating its effects in the animal models of nonbacterial prostatitis and urethral obstruction. Nonbacterial prostatitis was induced in adult Noble rats with the combined treatment of testosterone and 17beta-estradiol. The inflammatory foci categorized into three forms were counted and correlated with expression of an estrogen-responsive gene, progesterone receptor (PR), in the dorsolateral lobes of the rats on soy (+) and soy (-) diets. Development of obstructive voiding after neonatal estrogenization of Noble rats (NeoDES rats) was followed with urodynamic measurements in rats on soy (+) and soy (-) diets. The amounts of genistein and daidzein, two major soy-derived isoflavones, were measured in the urine of Noble rats by the high-performance liquid chromatography-photodiodearray method. Dietary soy decreased the total number of inflammatory foci while no demonstrable effects were seen on the cellular composition of the infiltrates. Soy did not increase the weights of the pituitary gland, testes, or sex accessory glands, but it did increase the number of PR-positive epithelial cells in the dorsolateral prostate. It also decreased the bladder pressures in NeoDES rats but did not increase the flow rates. The soy effects may be mediated by the strong estrogen influence involved in the animal models. Dietary soy had anti-inflammatory effects in the prostate but only marginal effects on the development of obstructive voiding in Noble rats. The anti-inflammatory effects of soy may contribute to the lower prevalence of prostatitis-like symptoms and the historically lower risk of benign prostatic hyperplasia in Japan; however, no evidence was found that regular consumption of soy influences the age-related development of lower urinary tract symptoms or decline of flow rate.     

The effect of total maxillary advancement on facial growth.

The effect of total maxillary advancement on the growing skull was examined in 25 pigs, subjected to facial operations of varied severity at the age of 5 weeks (elevation of periosteum, simple osteotomy, and osteotomy immobilized by wire fixation, with or without bone grafts) and in controls. When the animals were killed 8 months later, the body weight had increased tenfold and the skull size had doubled. In 5 pigs whose maxillae were advanced 10 mm by bone grafts, the relative increase in length was not maintained. The overall skull length showed no difference from the control measurements. The extent of the growth in the area adjacent to the osteotomy was less than in the controls, but the same as in pigs subjected to periosteal elevation only. Scattered areas of bone damage were seen with no consistent pattern. Incision of the periosteum over the frontal bone decreased the local blood supply, increased the adherence of the periosteum to the bone, and affected bone growth locally.     

The effect of active pedaling combined with electrical stimulation on spinal reciprocal inhibition

ObjectivePedaling is widely used for rehabilitation of locomotion because it induces muscle activity very similar to locomotion. Afferent stimulation is important for the modulation of spinal reflexes. Furthermore, supraspinal modulation plays an important role in spinal plasticity induced by electrical stimulation. We, therefore, expected that active pedaling combined with electrical stimulation could induce strong after-effects on spinal reflexes.DesignTwelve healthy adults participated in this study. They were instructed to perform 7 min of pedaling. We applied electrical stimulation to the common peroneal nerve during the extension phase of the pedaling cycle. We assessed reciprocal inhibition using a soleus H-reflex conditioning-test paradigm. The magnitude of reciprocal inhibition was measured before, immediately after, 15 and 30 min after active pedaling alone, electrical stimulation alone and active pedaling combined with electrical stimulation (pedaling + ES).ResultsThe amount of reciprocal inhibition was significantly increased after pedaling + ES. The after-effect of pedaling + ES on reciprocal inhibition was more prominent and longer lasting compared with pedaling or electrical stimulation alone.ConclusionsPedaling + ES could induce stronger after-effects on spinal reciprocal inhibitory neurons compared with either intervention alone. Pedaling + ES might be used as a tool to improve locomotion and functional abnormalities in the patient with central nervous lesion.     

The bactericidal effect of isoascorbic acid combined with mild heat

The thermal inactivation of Salmonella thompson, Escherichia coli, Staphylococcus aureus, Clostridium perfringens, Candida zeylanoides, Enterococcus faecium and E. faecalis was accelerated by the addition of sodium isoascorbate (1 mmol/l) to phosphate-buffer heating medium but not to complex food mixtures. The lethal effect of isoascorbate was nullified by heating under anaerobic conditions or by the addition of catalase. The scavengers of hydroxyl radicals, mannitol and formate were not protective whereas histidine was. Histidine may have protected by slowing the rate of isoascorbate autoxidation, a property common to other amino acids tested. Superoxide dismutase was not protective. Dehydroascorbic acid also enhanced heat killing and its action was also reversed by catalase. The bactericidal effects of mild heat plus isoascorbate or dehydroascorbic acid both apparently depend on oxidative processes but their relative effectiveness was not related to their respective rates of oxygen consumption or peroxide production. We speculate that site-specific redox reactions, involving amino-carbonyl intermediates are involved in the inactivation mechanism.
