Aim To evaluate the hypolipidemic effect of total phenylpropanoid glycoside extracted from Ligustrum robustum(Roxb.)Blume(CNTG)and its mecha-nisms.Methods The 60 hamsters were randomly divided into six groups,namely the control group,the model group,the positive control group(fenofibrate,150 mg·kg-1),the high(1 200 mg·kg-1),medium(600 mg·kg-1)and low(300 mg·kg-1)doses of CNTG groups.Only the control group was given control diet and other groups received high-fat diet.The changes of serum lipid were measured and analyzed in 1st week to ensure the successful establishment of the model.The drugs were administered daily for four weeks and the concentrations of lipids were determined in the 2nd week,3rd week and 4th week respectively.Quantitative real-time PCR and Western blot were used to assay the mRNA and protein expression of related signaling enzymes and proteins.Results Compared with the model group,the concentrations of serum TG,TC,LDL-C(P<0.05,P<0.01)and hepatic TG,TC(P<0.01)were effectively reduced in hamsters in CNTG-treated groups.Mechanism research found that CNTG increased the levels of phospho-AMPKα,LKB1 and phospho-LKB1 in liver(P<0.05).Conclusion CNTG prevents hyperlipidemia via activation of hepatic LKB1-AMPK pathway.

Objective To detect the expression of IL-17 in renal transplant recipients by Luminex and evaluate the relationship between the level of serum IL 17 and early acute renal allograft rejection.Methods 38 kidney transplant recipients and healthy controls (HC,healthy volunteers,n =20) were selected in this study from January 2009 to October 2011.All patients were divided into two groups according to their allograft outcome as acute rejection group (ARG,n-18) and non-rejection group (NRG,n=20).The expression of serum IL-17 was detected by Luminex technique in two groups of kidney transplant recipients and HC.To evaluate the correlation between the level of serum IL-17 and early acute renal allograft rejection.Results The mean level of IL-17 in all renal transplant recipients 1.3 ± 1.9 pg/ml at the pre-transplantation was significantly lower than that in HC (6.9± 8.5 pg/ml,t=3.968,P＜0.001).The results highlighted that the level of serum IL-17 in ARG 3.4±5.8 pg/ml was significantly higher than that in NRG (0.5±0.4 pg/ml) on the 7th days post Kidney transplantation (post KTx,t=2.242,P =0.031).Kaplan-Meier survival analysis showed that the probability of rejectionfree survival in the higher levels group of IL-17 on the 7th days post-KTx was significant lower than that in the lower levels group (P＜0.001).The results of receiver operating characteristic curve showed that the sensitivity and specificity of the combined IL-17 to predict acute rejection were 66.67％ and 100％,respectively.Conclusion The serum IL-17 levels in renal transplant recipients on the 4th and 7th post-KTx days can predict early renal transplant rejection.

Chinese prescription medicine in Japan derives from China's traditional Chinese medicine. Yet during the long histroy of development, the management system of production, quality standard, and registration have been gradually establised in Japan. Research and development pattern and quality control management system for Chinese prescription medicine are formed and are different from those in China. Many of them are different with our current situation, especially in the aspect of quality management. Thus their experience is worth learning and using for reference.

The dissolution of Panacis Quinquefolii Radix ultrafine granular powder and common powder, traditional pieces in water and simulated gastric juice in vitro was compared, and the effect of particles size of Panacis Quinquefolii Radix on the dissolution was studied. HPLC method was used for determination of five ginsenosides including Rg1, Re, Rb1, Rc and Rd from ultrafine granular powder and common powder, traditional pieces of Panacis Quinquefolii Radix at different points in time, furthermore, the dissolution curves of Panacis Quinquefolii Radix ultrafine granular powder and common powder, traditional pieces were obtained. The dissolution characteristics of the three Panacis Quinquefolii Radix forms were also compared in this study. According to the results, the dissolution rates of ginsenosides from ultrafine granular powder exceeded 90% of the total content with 5 min, significantly higher than that of the other two forms in water in vitro. At the same time, the dissolved amount of the ultrafine granular powder was fourteen percent higher than that of the traditional pieces and eight percent higher than that of the common powder. Under the condition of simulated gastric juice in vitro, the dissolution rates of ginsenosides from ultrafine granular powder were little lower than that of the other two, but the maximum dissolved amount of the former was fourteen percent higher than that of the common powder and five percent higher than that of the extracts. Therefore the conclusion is that micronization of Panacis Quinquefolii Radix contributed to dissolution of effective components.

This study aims to analyze and compare the effect of cell wall-broken decoction pieces, conventional decoction pieces and conventional powder of Rhodiolae Crenulatae Radix et Rhizoma on the intestinal flora of normal mice. The conventional bacterial culture and PCR-DGGE (polymerase chain reaction-denaturing gradient gel electrophoresis) were adopted for the mice after the oral administration for 14 days. According to the bacterial culture results, the 1/8 dose cell wall-broken decoction pieces group showed fewer Enterococcus and Escherichia coli bacillus but more Lactobacillus and Bifidobacterium than the conventional decoction pieces group and the traditional powder group (P <0.05). Meanwhile, on the basis of the PCR-DGGE results, the 1/8 dose cell wall-broken decoction pieces group revealed the highest Shannon-Wiener index (H) and species richness (S) among the seven groups, with extremely significant differences compared with the normal group (P <0.01), significant differences compared with the conventional decoction pieces group and the conventional powder group (P <0.05) and a high intra-group similarity. In conclusion, the long-term intake of 1/8 dose Rhodiolae Crenulatae Radix et Rhizoma cell wall-broken decoction pieces showed a certain effect in regulating intestinal tract by promoting the growth of Lactobacillus and Bifidobacterium. Furthermore, the intestinal flora community will become more stable.

OBJECTIVETo study the causes of orchiectomy in different age groups.

METHODSWe retrospectively reviewed the clinical data about 291 cases of orchiectomy performed between March 1993 and October 2014 and analyzed the causes of surgery and their distribution in different age groups.

RESULTSThe main causes of orchiectomy were testicular torsion (45.8%), cryptorchidism (32.5%) and testicular tumor (16.9%) in the patients aged 0-25 years, testicular tumor (42.4%), cryptorchidism (25.9%) and tuberculosis (10.6%) in those aged 26-50 years. Prostate cancer was the leading cause in those aged 51-75 years (77.6%) or older (84.0%)), and testicular tumor was another cause in the 51-75 years old men (10.2%). Prostate cancer, testicular tumor, cryptorchidism, and testicular torsion were the first four causes of orchiectomy between 1993 and 2009. From 2010 to 2014, however, testicular tumor rose to the top while prostate cancer dropped to the fourth place.

CONCLUSIONThe causes of orchiectomy vary in different age groups. The proportion of castration for prostate cancer patients significantly reduced in the past five years, which might be attributed to the improvement of comprehensive health care service.

OBJECTIVE To explore the hypolipidemic mechanisms of the total phenylpropanoid glycosides from Ligustrum robustum (Roxb.)Blume (LRTPG)in hamsters using proteomics technique. METHODS The hamsters were fed with a high fat diet to induce hyperlipidemia.Then LRTPG of high (1.2 g·kg-1),medium(0.6 g·kg-1)and low(0.3 g·kg-1)doses were administrated daily for 4 weeks.Then the concentrations of plasma and hepatic lipids were determined using enzymic methods.The total protein was extracted from livers of the model group and the group treated with the high dose of LRTPG for label-free quantitative proteomics. RESULTS LRTPG significantly reduced the concentrations of plasma and hepatic lipids in hamsters fed a high fat diet. The proteomics data showed that a total of 2231 proteins were identified,and 549 proteins were found to be differentially expressed between the model group and the group treated with LRTPG.Among the 549 proteins,93 proteins were up-regulated and 59 proteins were down-regulated, and 397 proteins were absent or not. And some of these proteins were much related to the lipid metabolism. Further, gene ontology (GO) analysis indicated metabolic process, transport, oxidation-reduction process, phosphorylation, signal transduction, lipid metabolic process were the main biological processes that those differentially expressed proteins participated. KEGG pathway analysis showed that those proteins were involved in several metabolic pathways including oxidative phosphorylation,non-alcoholic fatty liver disease(NAFLD),PI3K-Akt signaling pathway, cAMP signaling pathway, cGMP-PKG signaling pathway. CONCLUSION The proteomics study could provide valuable clues to help us to understand the hypolipidemic mechanisms of LRTPG much better.
