Asian Journal of Andrology 2019;21(4):360-364
We aimed to establish a novel rat model of seminal vesiculitis that would provide an effective approach to investigate the pathogenesis of this disease in the future. Eight male rats received the same operation, during which the root of one of the two seminal vesicles was partly ligatured with sutures and the other vesicle was left intact. The samples of seminal vesicles were harvested on the 8th day following the operation. Hematoxylin and eosin and Masson's trichrome stains were used to observe the histopathology and the presence of fibrous tissue in seminal vesicles, respectively. Immunoblotting and immunohistochemistry were applied to determine the tumor necrosis factor-alpha and cyclooxygenase-2 levels in seminal vesicle tissues. Real-time fluorescence quantitative polymerase chain reaction was performed to measure the gene expression levels of proinflammatory cytokines. H2O2levelsin the seminal plasma from the seminal vesicle were also measured. Hematoxylin and eosin staining suggested that there was inflammatory cell infiltration into the seminal vesicles treated by partial root ligation. The tumor necrosis factor-alpha and cyclooxygenase-2 proteins were significantly upregulated in the treated seminal vesicles. The tumor necrosis factor-alpha, cyclooxygenase, interleukin 6, and inducible nitric oxide synthase mRNA expression levels were also upregulated in the treated seminal vesicles. The H2O2 levels in the seminal plasma from seminal vesicles with partial root ligation were significantly elevated compared with those from vesicle left intact. In conclusion, partially ligating the root of the seminal vesicle via sutures in rats is an effective method to establish a seminal vesiculitis rat model.
3. Clinical and preclinical treatment of urologic diseases with phosphodiesterase isoenzymes 5 inhibitors: An update
Asian Journal of Andrology 2016;18(5):723-731
Phosphodiesterase isoenzymes 5 inhibitors (PDE5-Is) are the first-line therapy for erectile dysfunction (ED). The constant discoveries of nitric oxide (NO)/cyclic guanosine monophosphate (cGMP) cell-signaling pathway for smooth muscle (SM) control in other urogenital tracts (UGTs) make PDE5-Is promising pharmacologic agents against other benign urological diseases. This article reviews the literature and contains some previously unpublished data about characterizations and activities of PDE5 and its inhibitors in treating urological disorders. Scientific discoveries have improved our understanding of cell-signaling pathway in NO/cGMP-mediated SM relaxation in UGTs. Moreover, the clinical applications of PDE5-Is have been widely recognized. On-demand PDE5-Is are efficacious for most cases of ED, while daily-dosing and combination with testosterone are recommended for refractory cases. Soluble guanylate cyclase (sGC) stimulators also have promising role in the management of severe ED conditions. PDE5-Is are also the first rehabilitation strategy for postoperation or postradiotherapy ED for prostate cancer patients. PDE5-Is, especially combined with adrenoceptor antagonists, are very effective for benign prostatic hyperplasia (BPH) except on maximum urinary flow rate (Q max ) with tadalafil recently proved for BPH with/without ED. Furthermore, PDE5-Is are currently under various phases of clinical or preclinical researches with promising potential for other urinary and genital illnesses, such as priapism, premature ejaculation, urinary tract calculi, overactive bladder, Peyronie′s disease, and female sexual dysfunction. Inhibition of PDE5 is expected to be an effective strategy in treating benign urological diseases. However, further clinical studies and basic researches investigating mechanisms of PDE5-Is in disorders of UGTs are required.

Metabolic syndrome is closely related to target organ injury such as heart, brain, and kidney. And bilirubin is an effective antioxidant. At present, there is a lack of research data on metabolic syndrome and serum total bilirubin in longevity elderly people. This study aimed to study the prevalence of the metabolic syndrome and its correlation with serum total bilirubin level in nonagenarians and centenarians living in Hubei Zhongxiang Province. According to the demographic information provided by Zhongxiang Civil Affairs Bureau, 128 elderly people were interviewed and 11 of them were excluded. A total of 117 population were included in the study. Questionnaires, physical examination, and blood test were made. 117 subjects aged 90-113 years with an average age of (98.6±4.8) years old were analysed. The prevalence of metabolic syndrome and its diagnostic components were obesity 19.7%, hyperglycemia 29.9%, hypertension 94.0%, hypertriglyceridemia 33.3%, low high density lipoprotein-cholesterol (HDL-C) levels 17.1%, and metabolic syndrome 23.9%. Logistic regression analysis found that the total bilirubin level was negatively correlated with metabolic syndrome and triglyceride levels(

OBJECTIVETo investigate the mechanisms of lysophosphatidic acid (LPA) in stimulating invasion and metastatic colonization of ovarian cancer cells.
METHODSThe metastatic ability in vivo of ovarian cancer SK-OV3, HEY, OVCAR3, and IGROV1 cells was determined in tumor-bearing nude mouse models. Matrigel assay was used to detect the changes of response in vitro of ovarian cancer cells to LPA after Rac(-) or Rac(+) adenovirus treatment. LPA-induced Rho GTPase activation was detected by GST-fusion protein binding assay.
RESULTSThe peritoneal metastatic colonization assay showed overt metastatic colonization in mice receiving SK-OV3 and HEY cell inoculation, indicating that they are invasive cells. Metastatic colonization was not detected in animals receiving OVCAR3 and IGROV1 cells, indicating that these cells are non-invasive cells. In the matrigel invasion assay, exposure to LPA led to a notably greater migratory response in metastatic SK-OV3 and HEY cells (Optical density: SK-OV3 cells: 0.594±0.023 vs. 1.697±0.049, P<0.01; HEY cells: 0.804±0.070 vs. 1.851±0.095, P<0.01). But LPA did little in the non-metastatic OVCAR3 and IGROV1 cells (Optical density A: OVCAR3 cells: 0.336±0.017 vs. 0.374±0.007, P>0.05; IGROV1 cells: 0.491±0.036 vs. 0.479±0.061, P>0.05). LPA migratory responses of ovarian cancer cells were closely related to their metastatic colonization capabilities (r = 0.983, P<0.05). Rac(-) blocked the LPA response of invasive SK-OV3 and HEY cells (LPA-induced fold increase of cell migration: SK-OV3 cells: 2.988±0.095 vs. 0.997±0.100,P=0.01; HEY cells: 2.404±0.059 vs. 0.901±0.072, P=0.01). But Rac(+) confered the non-invasive cells with LPA response and invasion capability (LPA-induced fold increase of cell migration: OVCAR3 cells: 1.072±0.080 vs. 1.898±0.078, P<0.01; IGROV1 cells: 1.002±0.044 vs. 2.141±0.057, P<0.05). Among Rho GTPases, only Rac activation was different between ovarian cancer cell lines with different metastatic capability after LPA stimulation: Cdc42 could not be activated in both the invasive and non-invasive cell lines. RhoA could be activated in both the invasive and non-invasive cell lines. Rac could be activated by LPA in the invasive ovarian cancer cell lines. However, Rac could not be activated in the non-invasive cell lines.
CONCLUSIONLysophosphatidic acid stimulates invasion and metastasis of ovarian cancer cells through Rac activation.

Allergic rhinitis(AR) is an independent risk factor for allergic asthma. Some AR patients may have developed airway hyperresponsiveness(AHR) in the absence of asthma symptoms. In this stage, AHR is often neglected due to the absence of typical asthma symptoms. Exploring the clinically relevant risk factors for AHR in patients with AR, as well as the clinical indicators and biomarkers to predict AHR in patients with AR, is of great significance to the prevention of the occurrence of AHR and asthma. This review summarized the risk factors for the development of AHR in AR patients, and gave hints to the prevention of AHR in AR patients.

Pull-through operation is an effective procedure for the treatment of posterior urethral stricture and atresia.Traditional pull-through operation is often difficult to achieve the ideal outcomes due to factors such as major injury, imprecise end-to-end alignment and fixation.Our team has modified the traditional pull-through operation by applying ureteroscopy to perform precise end-to-end urethral alignment under direct vision without opening the bladder during the operation.Meanwhile, we use ultrasonic scalpel to reduce intraoperative bleeding and postoperative wound infection, improve the success rate of operation, reduce the recurrence rate of stenosis and the incidence of postoperative complications, and finally achieve the effects of minimally invasive and precision medicine.Furthermore, the shorter learning curve makes it a novel treatment of complex posterior urethral stricture or atresia after pelvic fracture.This paper describes in detail the specific steps of this procedure, analyzes the efficacy based on clinical data, and details the innovations and operation experience of it.
