Ningmitai Capsules combined with doxycycline hydrochloride for Ureaplasma urealyticumpositive chronic prostatitis / 中华男科学杂志

Objective@#To investigate the effects of Ningmitai Capsules (NMT) combined with doxycycline hydrochloride (DH) on chronic prostatitis induced by Ureaplasma urealyticum (Uu).@*METHODS@#This randomized controlled trial included 240 male patients with Uupositive chronic prostatitis, treated orally with NMT at 4 capsules tid (n= 35), DH at 100 mg bid (n = 78), and NMT+DH at the corresponding doses (n = 127), respectively, all for 2 successive weeks. At 1 week after drug withdrawl, we conducted routine urine analysis, EPS examination, and drug sensitivity test of the cultured Uu.@*RESULTS@#The positivetonegative rate of Uu was significantly higher in the NMT+DH group than in the NMT and DH groups (89.0% ［113/127］ vs 54.3% ［19/35］ and 71.8% ［56/78］, P< 0.05), so were the cure rate (25.2% vs 20.0% and 20.5%, P< 0.05) and total effectiveness rate (89.0% vs 54.3% and 71.8%, P< 0.05).@*CONCLUSIONS@#The combination of Ningmitai Capsules and doxycycline hydrochloride is more effective than either Ningmitai Capsules or doxycycline hydrochloride used alone in the treatment of Uupositive chronic prostatitis.

Changes of nerve growth factor and M3 subtype muscarinic receptor in the seminal vesicle of diabetic rats / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the effect of diabetic autonomic neuropathy on the seminal vesicle and search for the theoretical evidence for the prevention and treatment of diabetic infertility by observing changes in the contents of the nerve growth factor (NGF) and muscarinic M3 receptor in the seminal vesicle of diabetic rats.</p><p><b>METHODS</b>Diabetic models were established in 10 of the 15 male adult SD rats by intraperitoneal injection of streptozotocin (STZ), and the other 5 were included in a normal control group. Eight weeks after modeling, seminal vesicles were collected from the rats for HE and immunohistochemical staining.</p><p><b>RESULTS</b>Compared with the normal controls, the diabetic models showed a decreased number of smooth muscle cells, thinner cytoplasm of glandular epithelial cells and disordered structure in the seminal vesicle. The intensity of NGF-positive staining was significantly enhanced, but that of M3 markedly reduced in the diabetic group. There were statistically significant differences in the mean integrated optical density (IA) of muscarinic M3 receptors and NGF between the control and diabetic groups (0.0187 +/- 0.0024 vs 0.0100 +/- 0.0015 and 0.0209 +/- 0.0085 vs 0.0412 +/- 0.0117, P<0.01).</p><p><b>CONCLUSION</b>The changes in the expressions of NGF and M3 receptors in the seminal vesicle of diabetic rats suggest that diabetes mellitus may induce autonomic neuropathy of the seminal vesicle.</p>
