OBJECTIVETo explore the mechanisms of Qianjing Decoction in the treatment of oligoasthenospermia (OAS).
METHODSWe randomly divided 100 SPF male rats into five groups of equal number: normal, model, Huangjingzanyu, levocarnitine, and Qiangjing. OAS models were established in the animals followed by intragastrical administration of normal saline, ornidazole, Huangjingzanyu Capsules (200 mg per kg body weight per day), levocarnitine (100 mg per kg body weight per day), and Qianjing Decoction (10 g per kg body weight per day), respectively, qd, for 4 successive weeks. Then, we detected the concentration and motility of the epididymal sperm, obtained the contents of superoxide dismutase (SOD), malonaldehyde (MDA), glutathione peroxidase (GSH-Px), lactate dehydrogenase (LDH), α-glucosidase, and fructose in the epididymis, and determined the mRNA expressions of nuclear factor erythroid 2-related factor 2 (Nrf2) and succinate dehydrogenase (SDH) in the epididymal tissue of the rats by real-time PCR.
RESULTSThe concentration and motility of the epididymal sperm in the model, Huangjingzanyu, levocarnitine, and Qianging groups were (35.34 ± 4.22) x 10(6)/ml and (40.04 ± 7.05)%, (48.12 ± 5.56) x 10(6)/ml and (62.46 ± 7.12)%, (47.14 ± 4.87) x 10(6)/ml and (63.23 ± 6.34)%, and (50.25 ± 5.08) x 10(6)/ml and (66.34 ± 7.58)%, respectively, all significantly lower than in the normal group ([53.05 ± 4.55] x 10(6)/ml and [70.20 ± 8.54]%) (P < 0.05), but remarkably higher in the Huangjingzanyu, levocarnitine, and Qiangjing groups than in the model rats (P < 0.05). Compared with the thinned epididymal lumen walls, decreased sperm count, and disorderly and loose arrangement of the lumens in the OAS models, the rats in the Huangjingzanyu, levocarnitine, and Qiangjing groups showed evidently thicker epididymal lumen walls, with the lumens full of sperm cells and arranged regularly and compactly, similar to those of the normal rats. The levels of SOD and GSH-Px were significantly lower but that of MDA markedly higher in the model rats ([84.12 ± 23.25], [10.56 ± 3.02], and [14.04 ± 2.06] nmol/mg) than in the normal group ([110.04 ± 19.56], [17.25 ± 3.56], and [8.87 ± 1.35] nmol/mg) (P < 0.05), while the former two indexes remarkably higher and the latter one significantly lower in the animals treated with Qiangjing Decoction ([120.56 ± 23.68], [16.34 ± 3.12], and [8.45 ± 1.56] nmol/mg), Huangjingzanyu Capsules ([115.34 ± 21.35], [15.23 ± 3.67], and [8.33 ± 1.54] nmol/mg), and levocarnitine ([116.67 ± 22.67], [15.35 ± 3.45], and [8.05 ± 1.78] nmol/mg) than in the models (P < 0.05). The levels of fructose, LDH and α-glucosidase were decreased markedly in the OAS models ([100.22 ± 12.12] mg/[ ml x g], [322 ± 46.13] U/[ ml x g], and [10.48 ± 2.33] U/[ml x g]) as compared with the normal rats ([128.12 ± 13.45] mg/[ml x g], [428 ± 35.12] U/[ml x g], and [15.34 ± 3.12] U/[ ml x g]) (P < 0.05), remarkably higher in the rats treated with Qiangjing ([130.23 ± 13.67] mg/[ml x g] [455 ± 51.50] U/[ml x g], and [18.56 ± 4.67] U/[ml x g]), Huangjingzanyu ([124.16 ± 14.02] mg/[ml x g], [ 419 ± 43.14] U/[ml x g], and [17.64 ± 4.08] U/[ml x g]), and levocarnitine ([123.34 ± 14.02] mg/[ml x g], [430 ± 31.80] U/ [ml x g], and [16.85 ± 5.55] U/[ml x g]) than in the models (P < 0.05). The Nrf2 mRNA expression was significantly reduced in the models as compared with the normal rats (P < 0.05) but remarkably increased in the Huangingzanyu, Qiangjing and levocarnitine groups as compared with the model and normal animals (P < 0.05). The SDH mRNA expression was significantly lower in the model than in the normal rats (P < 0.05) but markedly elevated in the Huangjingzanyu, Qiangjing and levocarnitine groups as compared with the model and normal animals (P < 0.05), remarkably higher in the Qiangjing than in the Huangjingzanyu group (P < 0.05).
CONCLUSIONOrnidazole induces OAS in rats, which is closely associated with excessive oxidation and energy metabolism dysfunction. Qiangjing Decoction can improve and even reverse ornidazole-induced OAS in rats as well as improve the ultrastructure of their testicular and epididymal tissues. Antioxidation and improvement of energy metabolism are probably the action mechanisms of Qiangjing Decoction in the treatment of OAS.

Papillary cystadenoma of the epididymis is a rare benign tumor, accounting for only 4 per cent of all epididymal tumors. Histologically, it can be confused with metastatic renal cell carcinoma. This extremely rare lesion may occur sporadically or as a manifestation of von Hippel-Lindau(VHL) disease. The present paper reported a case of papillary cystadenoma accompanied by testicular atrophy with no signs of VHL syndrome or infertility. To date, no similar case was reported in the literature. The tumor measured 5.0 cm x 4.0 cm x 4.0 cm and was located in the right epididymis. Histopathologic examination of a surgically removed specimen indicated a primary papillary cystadenoma. Histomorphologically, these tumors are characterized by cysts with colloid-like contents and papillary formations of light epithelium. Since metastatic renal cell carcinoma may be histologically similar to papillary cystadenoma, the importance of long-term urologic follow-up for possible presentation of renal cell carcinoma is discussed.

BACKGROUND AND PURPOSE: This study evaluated the clinical value of detachable-balloon embolization for traumatic carotid-cavernous fistula (TCCF), focusing on the frequency, risk factors, and retreatment of recurrence. METHODS: Fifty-eight patients with TCCF underwent transarterial detachable-balloon embolization between October 2004 and March 2011. The clinical follow-up was performed every 3 months until up to 3 years postprocedure. Each patient was placed in either the recurrence group or the nonrecurrence group according to whether a recurrence developed after the first procedure. The relevant factors including gender, fistula location, interval between trauma and the interventional procedure, blood flow in the carotid-cavernous fistula, number of balloons, and whether the internal carotid artery (ICA) was sacrificed were evaluated. RESULTS: All 58 TCCFs were successfully treated with transarterial balloon embolization, including 7 patients with ICA sacrifice. Recurrent fistulas occurred in seven patients during the follow-up period. Univariate analysis indicated that the interval between trauma and the interventional procedure (p=0.006) might be the main factor related to the recurrence of TCCF. The second treatments involved ICA sacrifice in two patients, fistula embolization with balloons in four patients, and placement of a covered stent in one patient. CONCLUSIONS: Detachable balloons can still serve as the first-line treatment for TCCFs and recurrent TCCFs despite having a nonnegligible recurrence rate. Shortening the interval between trauma and the interventional procedure may reduce the risk of recurrence.

OBJECTIVETo investigate the effects of Biejia Ruangan Tablet ([symbol in text], BRT)-containing serum on the expression of matrix metalloproteinase (MMP-9) and tissue inhibitor of metalloproteinase (TIMP-1) in cultured renal interstitial fibroblasts.
METHODSDifferent BRT-containing sera were prepared by gastric gavages to rats with the high-dose (7 g/kg), mid-dose (3.5 g/kg), and low-dose (1.75 g/kg) BRT respectively. The expression of extracellular matrix in NRK-49F cells was induced by treatment with human transforming growth factor-β1 (recombined human TGF-β1), and BRT-containing serum. Western blotting and Northern blotting were used to measure type I and III procollagen, MMP-9, and TIMP-1.
RESULTSThe high dose BRT-containing serum could decrease the type I and III procollagen gene expression which boosted by TGF-β1, at the same time cut down TIMP-1 protein and gene expression which increased by TGF-β1 (P <0.05). Treatment of cells with recombined human TGF-β1 had no significant effect on MMP-9 expression and BRT-containing serum also had no effect on MMP-9 expression.
CONCLUSIONSHigh dose BRT has anti-fibrosis effects in NRK-49F cells, as indicated by its inhibition of type I and III procollagen and TIMP-1 expression.

Virus inactivation of plasma can be achieved by methylene blue/photochemical method. To investigate the effect of this method on immunological properties and biochemical functions of plasma components, the virus-inactivation method was performed on single-donor plasma that was exposed to visible light (40,000 lux) at room temperature for 1 h in the presence of 1 micro mol/L methylene blue. The results showed that activities of the factor VIII, PT and APTT were decreased to a certain degree while most of other plasma proteins were not affected significantly. Human plasma components including albumin, glucose and minerals as well as plasma pH were also not affected. By using different electrophoreses and immunochemical techniques, no neoantigens were found in photodynamically treated plasma and electrophoretic mobility revealed identical patterns for untreated and treated plasma. In conclusion, methylene blue/photochemical method dose not considerably influence the properties of major of plasma components.
