New Mechanism of Herb-herb Interaction between Ginseng and Trogopterus Based on CYPs in Rat Livers

The study was designed to investigate the potential mechanism of herb-herb interaction between ginseng and Trogopterus （Trg） based on Cytochrome P450 isozymes （CYPs） in rat livers. We estimated the influence on CYP1A2, CYP2E1, and CYP3A1/2 activity caused by ginseng and Trg used in combination. The CYP1A2 and CYP2E1 enzyme activity were induced by ginseng and Trg used in combination. And this induction effect was caused via inducing CYP1A2 and CYP2E1 protein expression which was supposed caused by inducing the gene expression of CYP1A2 and CYP2E1.

Liuwei Dihuang,a traditional Chinese herbal formula,suppresses chronic inflammation and oxidative stress in obese rats

OBJECTIVE： To investigate the anti-inflammatory, anti-oxidative stress, and adipokine-ameliorating effects of Liuwei Dihuang （LWDH）, a traditional Chinese herbal formula, in obese rats. METHODS： After 2 weeks of acclimation with free access to regular rodent chow and water, obese-prone-caesarean-derived （OP-CD） rats were fed a modified AIN-93G diet containing 60% energy from fat. Treatment was performed twice daily by gavage feeding with 500, 1 500, or 3 500 mg/kg body weight LWDH suspended in water （n=12 rats per group）. Twelve obese-resistant-CD （OR-CD） rats were fed the atherogenic diet and gavaged with water, and served as the normal control. Blood biomarkers of inflammation, oxidative stress and adiponectin were measured post-sacrifice and used to determine the treatment effect of LWDH and assess the suitability of OR/OP-CD rats for studying these parameters. RESULTS： After 9 weeks of treatment, LWDH lowered serum C-reactive protein （CRP） and tumour necrosis factor-α （TNF-α） levels. Serum interleukin-6 （IL-6） levels showed a tendency towards reduction, but were not significantly different from the OP-CD control. Liver superoxide dismutase （SOD） activity was increased in response to all three doses of LWDH, while the levels of reduced （GSH） and oxidized glutathione （GSSG） and thiobarbituric acid reactive substances （TBARS） were unchanged. Serum adiponectin levels were increased in response to oral administration of LWDH at the dose of either 500 or 1 500 mg/kg body weight. In addition, comparisons between OR-CD and OP-CD rats revealed differential, and for some biomarkers, conflicting characteristics of high-fat diet-fed OP-CD rats in reference to obese human subjects in terms of inflammatory and oxidative stress biomarkers and circulating adiponectin levels. CONCLUSION： The results show, for the first time, the anti-inflammatory, anti-oxidative stress and adiponectin-ameliorating effects of LWDH in obese rats. The suitability of the OP-JOP-CD rat model as

UniPron is A Fully Effective Non-hormonal Reversible Contraceptive in Baboon Model （Papio Anubis）

Objective To determine the safety and efficacy of UniPron as a reversible contraceptive.
Methods Vaginal swabs were obtained before and after UniPron administration, cultured onto appropriate culture media and bacteria identification was done based on type of media used, Gram stain reactions, colony morphology and biochemical tests. Vaginal biopsy tissues were processed using paraffin wax method, stained with hematoxylin and eosin and examined under light microscopy to determine the effect of the product on vaginal tissues. The effect of UniPron on sperm was examined by mixing the product with electroejaculated spermatozoa in vitro at different concentrations. For efficacy studies, male baboons of proven fertility were mated with UniPron treated or untreated females of proven fertility during the fertile stages.
Results All the five females （100%） that were treated with UniPron did not conceive and they regained total fertility when the treatment was stopped while all the controls conceived. At a concentration of 40%, UniPron completely immobilized spermatozoa in an in-vitro system. UniPron mechanism of action was by lowering the vaginal pH and on application in baboon, the pH was lowered for at least 3 h after which it went back to normal.
Conclusions As we plan for a study to test UniPron as a microbicide to prevent STIs including HIV, our current study has established that this novel product is effective in contraception and harmless to vaginal tissues and vaginal microbial flora in a baboon model （Papio anubis）.     

Mechanical tests on the reconstructed anterior cruciate ligament fixed with allogenetic cortical bone cross-pin on the femoral side

Background Anterior cruciate ligament reconstruction （ACLR） has developed dramatically in the last century.Now,ACLR has become a reliable and productive procedure.Patients feel satisfied in 〉90% cases.The aim of this study was to evaluate the feasibility of allogenetic cortical bone cross-pin （ACBCP） used as a clinical fixation method in anterior cruciate ligament reconstruction on the femoral side based on biomechanical tests in vitro.Methods The specimens were provided by the bone banks of the First Affiliated Hospital of People＇s Liberation Army of General Hospital from September 2011 to June 2012.Fresh deep frozen human allogenetic cortical bone was machined into cross-pins which is 4.0 mm in diameter and 75.0 mm in length.Biomechanical parameters compared with Rigidfix were collected while cross-pins were tested in double-shear test.The load-to-failure test and cycling test were carried out in a goat model to reconstruct anterior cruciate ligament with Achilles tendon autograft on the femoral side fixed by human 4.0 mm ACBCP and 3.3 mm Rigidfix served as control.Maximum failure load,yield load,and stiffness of fixation in single load-to-failure test were compared between the two groups.Cycle-specific stiffness and displacement at cycles 1,30,200,400,and 1 000 were also compared in between.Results In double-shear test both maximum failed load and yield load of 4.0 mm humanACBCP were （1 236.998±201.940） N.Maximum failed load and yield load of Rigidfix were （807.929±110.511） N and （592.483±58.821） N.The differences of maximum failed load and yield load were significant between ACBCP and Rigidfix,P 〈0.05.The shear strength of ACBCP and Rigidfix were （49.243±8.039） MPa and （34.637±3.439） MPa,respectively,P 〈0.05.In the load-to-failure test ex vivo,yield load and maximum failed load of ACBCP fixation complexity （（867.104±132.856）N,（1 032.243±196.281） N） were higher than those of Rigidfix （（640.935±42.836） N,（800.568±64.890） N,P 〈0.05）.However,s     

中医疗法治疗运动性疲劳的研究进展

随着竞技体育的发展，运动员经常承受着大负荷、超强度的体力训练，因此极易产生运动性疲劳。疲劳的出现使肌内压增高，局部缺血，造成氧化代谢、H^＋排出率与pH值降低，血乳酸增高，从而影响肌纤维神经传导速度和肌内收缩力量，减弱了肌肉保护能力。致使较多的冲击力传到骨骼上，故易导致疲劳骨折的发生,严重影响了运动员的训练和比赛成绩，对运动员身心产生不必要的伤害。运动性疲劳消除手段的研究一直是竞技体育工作和运动医学关注和研究的焦点。     

Effects of tacrolimus and cyclosporine treatment on metabolic syndrome and cardiovascular risk factors after renal transplantation: a meta-analysis

Background The therapeutic success of renal transplantation has been largely attributable to the development of effective and balanced immunosuppressive treatment regimens.This study provides a meta-analysis of a series of randomized controlled trials that compared the effects of tacrolimus and cyclosporine on metabolic syndrome （MetS） and cardiovascular risk factors after renal transplantation.Methods We searched various electronic databases and bibliographies,including MEDLINE,the Cochrane Central Register of Controlled Trials,and EMBASE,for relevant studies published prior to October 2012.Results Our meta-analysis included five randomized controlled trials that examined a total of 923 patients.The tacrolimus group and the cyclosporine group exhibited no significant differences in MetS incidence after renal transplantation; risk ratio （RR）：1.06,95％ confidence interval （C/）：0.73-1.55,P=0.76.Cyclosporine treatment was associated with a higher incidence of hyperlipidemia （RR：0.50,95％ CI：0.39-0.64,P ＜0.01）.Although there were no statistically significant differences,cyclosporine treatment was associated with a higher incidence of hypertension （RR：0.91,95％ CI：0.83-1.00,P=0.06） after renal transplantation compared to tacrolimus treatment,and tacrolimus treatment was associated with a higher incidence of diabetes after renal transplantation （RR：1.79,95％ CI：0.98-3.27,P=0.06） compared to cyclosporine treatment.Conclusions Compared to tacrolimus treatment,cyclosporine treatment was associated with a higher incidence of hyperlipidemia.Future large-scale studies are expected to be conducted to further confirm our findings.
