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 observe the effects of L-tetrahydropalmatine (L-THP) on concentrations of neurotransmitter amino acids in mice with cerebral ischemia and to discuss the mechanisms of L-THP in tyreating cerebral ischemia.

METHODMice were randomly divided into six groups: control group, cerebral ischemia group, L-THP treated group (doses were 14, 28, 56 mg x kg(-1) respectively) and Ginkgo biloba extract treated group. Concentrations of Glu and GABA were determined by HPLC.

RESULTCompared with control group, Glu and GABA in mice with cerebral ischemia were much higher. The ratio of Glu/GABA increased significantly. L-THP markedly reduced the concentrations of Glu and the ratio of Glu/GABA in mice with cerebral ischemia.

CONCLUSIONDecrease in Glu concertration and ratio of Glu/GABA may be one of the mechanisms of L-THP in treating cerebral ischemia.

OBJECTIVETo evaluate the value of radiofrequency ablation in the treatment of small hepatocellular carcinoma (HCC).

METHODSMEDLINE (1966 - 2008), EMBASE (1966 - 2008), CBMdisc (1978 - 2008) were searched. The Cochrane Library, Evidence Base Medicine Reviews (Ovid Edition), Cancerlit (1993 - 2008) and so on, date of last search: 30 January 2008. There were no restrictions in language. Randomized controlled trials (RCTs) and non-RCTs were both included in this study, and the quality of each included study was assessed. Meta-analysis was performed by RevMan 4.2 software.

RESULTSFour prospective controlled studies and two retrospective studies met the inclusion criteria. The results of meta-analysis showed that 1-, 3-, 4-year survival rates and 1-year tumor-free survival rate had not statistically significant difference in RFA group compared with surgical resection group (P > 0.05), but surgical resection was more effective to improve 3-year tumor-free survival rate than RFA (P < 0.05).

CONCLUSIONSThe effect of RFA therapy on small HCC is similar to resection, RFA could be considered as the first-line treatment of choice for surgical candidates with small HCC in cirrhotic patients.

OBJECTIVETo research the hereditary stability of Dendrobium huoshanense which were subcultured 7-8 times in the same tissue culture system.

METHODUsing three primers of arbitrary decamer oligonucleotide sequences from 20 primers for DNA amplification, random amplified polymorphic DNA (RAPD) were performed.

RESULTThe genetic similarity coefficient was varied from 85.4% to 98.4%. The variation of protocorm, germination and monoleaf were rather more notable than that of bileaf and inflorescence.

CONCLUSIONThe variation of the same pod is quite small. It is feasible to set up the rapid propagation system of D. huoshanense

OBJECTIVETo establish a chiral separation method for determination of fluvastatin enantiomer with in vitro cellular model.

METHODSThe determination was performed on Chiralpak AD column (4.6 mm × 250 mm); and the phase consisted of hexane-isopropanol-trifluoroacetic acid (90:10:0.1) at a flow rate of 0.5 ml/min with UV detection of 239 nm.

RESULTThe standard curve was linear over the concentration range of 20 μmol/L-300 μmol/L (r² = 0.9993, r² = 0.9997). The recovery for this assay was (99.4 ± 0.8)%, precision for inter-assay and intra-assay was <10 %.

CONCLUSIONThe normal-phase HPLC chiral separation method was accurate and suitable for study on the stereoselectivity of fluvastatin with in vitro cellular model.

Objective To observe the effect of ginsenoside Rb1,the most abundant ginsenoside in ginseng root,on differentiation and lipolysis of 3T3-L1 cells and to explore its anti-diabetic mechanism.Methods 3T3-L1 preadipoeytes were induced under standard differentiation process in the presence of 0.1,1,10,100?mol/L ginsenoside Rb_1 for 6 days.Oil red O staining,measurement of triglyceride contents and glucose uptake assay were performed.The expressions of mRNA and protein of PPAR?2,C/EBP?,ap2,glucose transporter (Glut) 1,and Glut4 were analysed with quantitative real time-PCR and Western blot.The binding affinity of Rb_1 to PPAR?-LBD was evaluated by Surface Plasmon Resonance (SPR).Lipolysis of adipocytes was examined by the measurement of glycerol released from adipoeytes treated with Rb_1 for 1 h.Results Ginsenoside Rb_1 facilitated differentiation of 3T3-L1 preadipoeytes in a dose-depondent manner.10?mol/L ginsenoside Rb_1 increased lipid accumulation by about 56%.Treatment of differentiating adipocytes with 10?mol/L ginsenoside Rb_1 increased the expressions of PPAR?2 and C/EBP?mRNA and protein,as well as mRNA expression of ap2,one of their target genes.After treatment of differentiating adipoeytes with Rb_1,basal and insulin-mediated glucose transport augmented significantly accompanied by up-regulations of mRNA and protein level of Glut4,but not of Glutl.SPR showed Rb_1 could bind to PPAR?which suggested Rb_1 was a ligand of PPAR?.Ginsenoside Rb_1 inhibited basal lipolysis in adipoeytos in a dose-dependent manner.However,it did not affect isoproterenol-stimulated lipolysis.Conclusion As a PPAR?ligand,ginsenoside Rb_1 promotes adipogenesis,inhibitas basal lipolysis and inereasos basal and insulin-mediated glucose transport in cultured adipoeytes.Therefore,anti-diabetic and insulin-sensitizing activity of ginsenosides is,at least in part,involved in the enhancing effect on PPAR?2 and C/EBP?expressions,hence promoting adipogenesis and glucose uptake,and inhibiting lipolysis in adipocytes.
