Previous studies have shown that ginsenoside Rb1 (Rb1), one of active components in ginseng, can activate insulin signaling pathway and promote translocation of glucose transporters (GLUTs) to increase glucose uptake in adipocytes. However, the effect of Rb1 on the expressions of GLUTs remains unknown. In this study, the effects of Rb1 on GLUT1 and GLUT4 were observed in 3T3-L1 adipocytes and epididymal adipose tissue of db/db obese diabetic mice. Male db/db mice were treated with Rb1 by intraperitoneal injection at the dosage of 20 mg x kg(-1) for 14 d. Rb1 reduced HOMA-IR significantly (P < 0.05, n = 5), and FBG and FINS sowed declining trend after treatment with Rb1. Rb1 recovered the expressions of GLUT1 and GLUT4 and phosphorylation of AKT in adipose tissue of db/db mice. In vitro, glucose consumption in 3T3-L1 adipocytes treated with 10 micromol x L(-1) Rb1 for 24 h was elevated (P < 0.05, n=3), and mRNA of GLUT1 and GLUT4 were up-regulated (P < 0.05, n=3) and proteins of GLUT1 and GLUT4 were also increased. AKT was activated in adipocytes treated with Rb1 for 3 h. It can be concluded that ginsenoside Rb1 can up-regulate the expression of GLUTs in adipose tissue, in addition to activate insulin signalling pathway, which may partially account for its insulin sensitizing activity and regulating effect of glucose metabolism.

Ginsenoside Rb1 is an active component in ginseng. Previous in vitro experiments showed that ginsenoside Rb1, could inhibit lipolysis and promote glucose transporter in adipocytes. This study focused on the effect of ginsenoside Rb1 in insulin resistance and ectopic fat deposit in obese mice induced by high fat diet and its molecular mechanism. Obese male C57/L mice induced by high fat diet were randomly divided into the diet-induced obesity group (DIO group), the ginsenoside Rb1 group (Rb1 group) and the rosiglitazone group (Rog group), and continuously fed with high fat diet. In addition, male C57/L mice fed with normal diet were selected as the normal group (NC group). Mice in Rb1 group and Rog groups were intraperitoneally injected with ginsenoside Rb1 and rosiglitazone with the dosage of 20 mg x kg(-1) and 10 mg x kg(-1), respectively. NC and DIO groups were intraperitoneally injected with the same amount of saline. Two weeks later, the intraperitoneal glucose tolerance test (IPGTT) was performed. Three days later, the mice were killed, and their serum samples were collected to detect insulin and free fatty acid (FFA). Their livers were weighed to examine the triglyceride content, and a pathological detection was performed. Epididymal adipose tissues were weighed, and PDE3B, HSL and perilipin were detected by Western blotting. The results showed that the treatment with ginsenoside Rb1 for two weeks could improve the glucose tolerance of obese mice. Except for 0-120 min, the areas under the glucose tolerance curve (0-30 min, 0-60 min and 0-90 min) in the Rb1 group were less than that in the DIO group (P < 0.05, n = 5), with a much lower HOMA-IR (P < 0.05, n = 5). The fat level of obese mice was significantly reduced by Rbl (P < 0.05, n = 5), and so were liver weight/weight (P < 0.05, n = 8). The increased serum FFA of obese mice declined after the treatment of Rb1 (P < 0.05, n = 8). Rb1 could partially recover the expression of perilipin in adipose tissues, but without obvious change in the expressions of PDE3B and HSL and the phosphorylated activation. The above findings indicated that ginsenoside Rb1 could reduce the release of FFA and alleviate the ectopic deposit of triglyceride by up-regulating the expression of perilipin in adipose tissue, which may be one of its mechanisms for improving the insulin resistance and abnormal glucose metabolism of organisms.

To confirm the inactivating effect of chito-oligosaccharides on Tobacco mosaic virus (TMV) par ticles in vitro, the difference of TMV pathogenicity was evaluated according to the decrease of local lesion numbers after inoculating with TMV mixed with chito-oligosaccharides (DP3-10) in Nicotiana glutinosa, and the virion structural change was studied by transmission electron microscopy after mixed with chito-oligosaccharides. In the range of tested concentrations of chito-oligosaccharides (100-1000 microg /mL), the numbers of local lesions were strongly reduced with over 30% decrement, and the 88.4% reduction gained at the concentration of 600g /mL. It revealed that treatment with chito-oligosaccharide solution of 300-500 microg /mL directly broke TMV particles into tiny pieces of 50-150nm long, and that treatment with solutions of 600-1000 microg/mL caused virus particle agglomerated. The data presented here suggested that chito-oligosaccharides exerted strong inactivating effect on plant virus in vitro.

OBJECTIVETo investigate the feasibility of treatment for calculous pyonephrosis with first stage percutaneous nephrolithotomy under the standard access.
METHODSThirty-six cases of calculous pyonephrosis and 36 cases of urolithiasis with no pyonephrosis were treated by percutaneous nephrolithotomy. In the nephrostomy, the caliber was dilated to F24. All the operations were preformed through the EMS lithotrity system. The intrapelvic pressure was detected in the operation. The hemoculture before and after operation, the germi culture of urine, and the temperature and blood leucocyte changes after operation were recorded. All the patients were treated by antibiotics before and after the operation.
RESULTSAll the patients were treated successfully. The average intrapelvic pressure were 23.2 cmH(2)O in non-pyonephrosis group and 22.8 cmH(2)O in pyonephrosis group. Both of the groups had 1 case of transient bacteremia after the operation. No significant difference was found in the other indices between the two groups.
CONCLUSIONEMS lithotrity system is safe and feasible for treating calculous pyonephrosis with stage I percutaneous nephrolithotomy via the standard access.

Objective To observe the effect of Compoud Qingqin Liquids on renal function of rat model of uric acid nephropathy, and to discuss its protection of renal function. Methods The rat model was induced by gavaging adenine and feeding yeast. SD rats were randomly divided into control group, model group, positive group, and high-, medium-, low-dose groups of Chinese medicine. Blank control group and model group were daily gavaged with distilled water, positive control group was daily gavaged with allopurinol by 9.33 mg/kg, and high-, medium-, low-dose group of Chinese medicine was daily gavaged with Compound Qinggin Liguids by 3.77, 1.89, 0.09 g/(kg·d) respectively for 6 weeks. General condition of rats were observed, renal pathological changes were observed with light and electron microscope. Urine protein concentration, blood uric acid, blood urea nitrogen, creatinine and kidney weight index were respectively tested before and after treatment. Results There were no significant differences in eating, drinking and body weight between before and after modeling. Compoud Qingqin Liquids can obviously decrease the concentration of urine protein, blood uric acid, serum creatinine, blood urea nitrogen, and kidney weight index (P<0.05) of rats with uric acid nephropathy. Renal tubular epithelial cells atrophy and renal interstitial fibrosis of high-dose group of Chinese medicine were not evident. Conclusion Compoud Qingqin Liquids can protect the rats renal function against uric acid renal injury.

OBJECTIVETo explore the protective effect of L-carnitine (LC) on the reproductive function of male rats with asthenospermia induced by ornidazole (ORN).
METHODSForty male SD rats (200-230 g) were randomly divided into Groups A (control: 0.5% carboxymethylcellulose solution), B (medium-dose ORN: 400 mg/kg/d), C (medium-dose ORN + LC: ORN 400 mg/kg/d + LC 100 mg/kg/d), D (high-dose ORN: 800 mg/kg/d), and E (high-dose ORN + LC: ORN 800 mg/kg/d + LC 100 mg/kg/d). All the rats were treated via gastric gavage for 20 days consecutively, and then killed for the detection of sperm motility and the sperm count of the cauda epididymis.
RESULTSCompared with Group A, there was a significant decrease in sperm motility and sperm count in Groups B and D (P < 0.05), while Group C showed a significant increase in both the parameters as compared with B (P < 0.05), but with no significant difference from A (P > 0.05). Group E exhibited no obvious improvement in sperm motility and sperm count, with no difference from D (P > 0.05).
CONCLUSIONL-carnitine can improve the sperm motility and sperm count of the male rats with ornidazole-induced asthenospermia.

OBJECTIVETo investigate the effect of Compound Qingqin Liquid (CQL) on the expression level of angiotensin II (Ang II) and COX-2 mRNA transcription and protein expression in the renal tissue of rats with uric acid nephropathy.
METHODSSD rats were randomly divided into the blank control group, the model group, the positive drug group, the high, moderate, and low dose CQL group according to number randomization principle. The model was established by gastrogavage of adenine, accompanied with yeast feeding. Distilled water was given by gastrogavage to rats in the blank control group and the model group. Allopurinol at the daily dose of 9.33 mg/kg was given by gastrogavage to rats of the positive control group. CQL at the daily dose of 3.77 g/kg, 1.89 g/kg, and 0.09 g/kg was respectively given by gastrogavage to rats in the high, moderate, and low dose CQL groups. All treatment lasted for 6 weeks. Rats were randomly divided at week 4 (3 in the blank control group, and 6 in the rest groups), and the rest rats were killed at week 6. The renal tissue was extracted. The expression level of Ang II and COX-2 mRNA transcription were detected by RT-PCR. The expression level of Ang II was detected by ELISA. The expression level of COX-2 protein was detected by Western blot and immunohistochemical assay.
RESULTSCompared with the blank control group, except the mRNA expression of Ang II at week 4, the mRNA and protein expression of Ang II and COX-2 obviously increased at week 4 and 6 in the model group (P < 0.01, P < 0.05). The COX-2 protein expression at week 4 was obviously lower in the high and moderate dose CQL groups than in the model group and the low dose CQL group (P < 0.05); the average integral of optical density value was obviously lower in the positive control group than in the model group. Except the mRNA expression of Ang II in the high dose CQL group at week 6, the mRNA and protein expression of Ang II obviously decreased in the positive control group and each dose CQL group (P < 0.01, P < 0.05). Of them, the effects were better in the high and moderate dose CQL groups than in the positive control group and the low dose CQL group (P < 0.05, P < 0.01). Besides, the mRNA expression of COX-2, the average integral of optical density value were obviously lower in the positive control group and each dose CQL group than in the model group (P < 0.05). The protein expression of COX-2 was obviously lower in the high and moderate dose CQL groups than in the model group (P < 0.05). Of them, the mRNA expression of COX-2 was better in the moderate dose CQL group than in the positive control group (P < 0.05); the protein expression of COX-2 was better in the high dose CQL group than in the low dose CQL group (P < 0.05).
CONCLUSIONCQL was capable of lowering the expression level of Ang II, COX-2 mRNA transcription and protein expression, thus suppressing the inflammatory pathological injury of the renal tissue.
