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.

中医疗法治疗运动性疲劳的研究进展   总被引:1,自引:0,他引:1  
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。  相似文献

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.  相似文献

There have been numerous studies done to explore the diagnostic performance of quanti- tative diffusion-weighted (DW) MR imaging to differentiate between benign and malignant pancre- atic masses. However, the results have been inconsistent. We performed a meta-analysis to investigate whether DW-MR imaging can differentiate between these two diseases. Databases including MEDLINE, EMBASE and Cochrane Library were utilized to find relevant articles published between January 2001 and January 2014. A Stata version 12.0 and a Meta-Disc version 1.4 were used to de- scribe primary results. Twelve studies with 594 patients, which fulfilled the inclusion criteria, were enrolled for the analysis. The pooled sensitivity and specificity of DW imaging was 0.91 (95% CI: 0.84, 0.95) and 0.86 (95% CI: 0.76, 0.93) respectively. The area under the curve of the summary re- ceiver operating characteristic was 0.95 (95% CI: 0.93, 0.96). The results indicated that DW imaging might be a valuable tool for differentiating benign and malignant pancreatic masses.  相似文献

Objective To study the effect of Shenfu on the expression of bax and bcl-2 in small intestinal mucosal epithelial cells after ischemic reperfusion injury and explore the effect of Shenfu on small intestinal mucosal epithelial cells apoptosis. Methods 36 SD rats were randomized into three groups, each consisting of 12 rats: Sham group (S group), Ischemic reperfusion group (IR group), Shenfu group (SF group), Ischemic reperfusion models were made by ligated the superior menseneric artery for 1 hour followed by 2 hrs reperfusion. Histological mucosal damage in each group was graded according to Chiu's score. Immunohistochemistry detected the expression of bax and bcl-2, and obtained the optical density (OD) value using a color image pattern analysis system, and then calculated the ratio of bcl-2/bax. TUNEL method measured apoptotic intestinal mucosal epithelial cells, and calculated the apoptotic index. Results There were edema and epithelial impairment in part of villus and the integral was higher in SF group than S group (P〈0.05), but lower than IR group (P〈0.01). Compared IR group with S group and SF group, the average OD value of bcl-2 and bax had significant statistic difference (P〈0.01), and the average OD value of bcl-2 in SF group was higher than in S group (P〈0.05), meanwhile bcl-2/bax was significantly lower in IR group than in S group and SF group (P〈0.01), but that was higher in SF group than in S group (P〈0.05). Apoptotic index in IR group was significantly higher than that in other two groups (P〈0.01), and that in SF group was higher than in S group (P〈0.05). Conclusion Shenfu can enhance the expression of bcl-2, decrease the expression of bax, meanwhile increase the ratio of bcl-2/bax, inhibit small intestinal mucosal epithetlial cells apoptosis, and protect small intestine mucosal epithetlial after ischemic reperfusion.  相似文献

Background Previous studies have shown that prostaglandins (PGs) dramatically stimulate healing processes in bone.However,the effect of prostaglandin l2 (PGI2) on fracture healing remains unclear.To investigate the effect of PGI2,a study on fracture healing process in closed tibia fractures was designed.Methods Thirty-six Sprague-Dawley male rats were randomized into two groups.On the first day,their right tibias were fractured by three-point bending technique.The study group (n=18) received a single injection of 10 μg/kg iloprost for 5 days,while the control group (n=18) received saline solution in the same way.On the 7th,14th and 28th days following the fracture,six rats were sacrificed and their right legs were harvested in each group.The progression of fracture healing was assessed for each specimen by the scores of radiography (by Lane-Sandhu) and histology (by Huo et al).Results On the 7th day,the radiographic and histologic scores were equal.On the 14th day radiographic total score was 6 and histologic total score was 23 in the iloprost group,whereas radiographic total score was 11 and histologic total score was 33 in the control group.On the 14th day radiographic and histologic scores were significantly decreased in the iloprost group compared to the control group (P 〈0.05).On the 28th day radiographic total score was 12 and histologic total score was 37 in the iloprost group,whereas radiographic total score was 15 and histologic total score was 40 in the control group.On the 28th day although there was a decrease in radiographic and histologic scores of the iloprost group acording to control group,it was not statistically significant (P 〉0.05).Conclusion Iloprost delays fracture healing in early stage in rats.  相似文献

Background It has been argued that the benefits of reducing sodium loading may be offset by increased activation of the renin-angiotensin-aldosterone system (RAAS) and sympathetic nervous system. This study aimed to investigate the long-term effects of an increase in dialysis sodium removal on circulating RAAS and sympathetic system in hypertensive hemodialysis (HD) patients with "normal" post-HD volume status. Methods Thirty hypertensive HD patients were enrolled in this pilot trial. After one month period of dialysis with standard dialysate sodium of 138 mmol/L, the patients were followed up for a four months period with dialysate sodium set at 136 retool/L, without changes in instructions regarding dietary sodium control. During the period of study, the dry weight was adjusted monthly under the guidance of bioimpedance spectroscopy to maintain post-HD volume status in a steady state; 44-hour ambulatory blood pressure, plasma renin, angiotensin II (Ang II), aldosterone, and norepinephrine (NE) were measured. Results After four months of HD with low dialysate sodium of 136 mmol/L, 44-hour systolic and diastolic blood pressures (BPs) were significantly lower (-10 and -6 mmHg), in the absence of changes in antihypertensive medications. No significant changes were observed in plasma renin, Ang II, aldosterone, and NE concentrations. The post-HD volume parameters were kept constant. Conclusion Mildly increasing dialysis sodium removal over 4 months can significantly improve BP control and does not activate circulating RAAS and sympathetic nervous system in hypertensive HD patients.

Multiple-treatments meta-analysis is thought to be a feasible method to compare the efficacy and safety among different treatments, especially when there was no head-to-head research among some treatments. But sometimes some conclusions are inconsistent with the clinical experience. Recently, we read a multiple-treatment meta-analysis finished by Stefen Leucht et al, which was published in Lancet) The authors summarized the results of the RCT studies on 15 antipsychotics commonly used in practice; they also horizontally compared the efficacy and safety profile by the recta-analysis. We believe that the results provide more solid evidence for the rational usage of antipsychotics to the psychiatrists, also for the government to distribute health resources in a more reasonable way.  相似文献

This study was aimed to examine the effect of ovariectomy on visceral fat, serum adi- ponectin levels and lipid profile. Forty-five female Sprague DawIey rats were divided into three groups (n=15 each): ovariectomized group (OVX), ovariectomized plus estrogen-treated group (OVX+E2), and sham-operated group (SHAM). Body weight, abdominal adipose tissues, serum adiponectin and lipid profile were measured and compared among the groups after three-month feeding post-surgery. Signifi- cant increases in body weight and visceral fat were found in ovariectomized rats when compared with sham-operated ones and significant increases were also observed in serum adiponectin, triglyceride and very low density lipoprotein cholesterol levels in ovariectomized rats. Body weight, visceral fat and se- rum adiponectin levels were profoundly reduced in OVX+E2 group as compared with OVX group. It was concluded that ovarian hormone deficiency induced by ovariectomy leads to significant increases in body weight and visceral fat, along with increased serum adiponectin, triglyceride and very low density lipoprotein cholesterol levels in rats. Attenuation in these changes can be achieved by estrogen supple- mentation.  相似文献

Protein tyrosine phosphorylation is a major posttranslational modification used by cells to regulate signal transduction and essentially participate in every aspect of cellular physiologic and pathogenic processes. The protein tyrosine phosphatase (PTP) super family of enzymes coordinately function with protein tyrosine kinases in signaling pathways that underlie a broad spectrum of fundamental physiological processes. Abnormal regulation of tyrosine phosphorylation or deregulation of phosphorylation is known to result in neoplastic or non-neoplastic diseases. Having evolved into separate families that are structurally and mechanistically distinct, PTPs have been implicated in a variety of diseases and efforts have been made to seek therapeutic clues from them. The phosphatases of regenerating liver (PRL) PRL-1, PRL-2, PRL-3 (also known as PTP4A1, PTP4A2, and PTP4A3, respectively) constitute a subfamily of the protein tyrosine phosphatases that have been suggested to play a key role in oncogenic and metastatic phenotypes.5 Here we review what is known about this novel class of small, prenylated phosphatases and its value in diagnosis and therapy of solid tumors.  相似文献

OBJECTIVE: The stable quality of Chinese herbal medicines is a critical factor for their reliable clinical efficiency. An improved liquid-liquid extraction procedure and a liquid chromatographic method were developed to simultaneously analyze five anthraquinones (aloe-emodin, rhein, emodin, chrysophanol and physcion) in a Chinese traditional hospital preparation, Fuyankang mixture, in order to quantitatively control its quality in a more effective way. METHODS: A more economical and repeatable extraction procedure based on conventional liquid-liquid extraction technique was developed and used to extract five marker components in Fuyankang mixture. These anthraquinones were separated in less than 20 min on a C18 column with methanol and 0.1% phosphoric acid (88:12, v/v) as mobile phase. The method was validated for specificity, precision, spiked recovery and stability. RESULTS: Compared to conventional liquid-liquid extraction, the improved liquid-liquid extraction was found to be more effective for simultaneous extraction of anthraquinones from an aqueous Chinese herbal preparation, especially for hydrophobic compounds. The improved extraction method was successfully applied to determine the content of five marker components in Fuyankang mixture by the means of reverse phase high-performance liquid chromatography. CONCLUSION: The improved extraction procedure may be suitable for routine quality control of Fuyankanq mixture and other traditional preparations at city-level hospitals in China.  相似文献

Background The bacterial endotoxins test (BET) is a method used to detect or quantify endotoxins (lipo-polysaccharide,LPS) and is widely used in the quality control of parenteral medicines/vaccines and clinical dialysis fluid.It is also used in the diagnosis of endotoxemia and in detection of environment air quality control.Although BET has been adopted by most pharmacopoeias,result judgment algorithms (RJAs) of the test for interfering factors in the BET still differ between certain pharmacopoeias.We have evaluated RJAs of the test for interfering factors for the revision of BET described in the Chinese Pharmacopoeia 2010 (CHP2010).Methods Original data from 1 748 samples were judged by RJAs of the Chinese Pharmacopoeia 2010,the Japanese Pharmacopoeia 2011 (JP2011),the European Pharmacopoeia 7.0 (EP7.0),the United States Pharmacopoeia 36 (USP36),and the Indian Pharmacopoeia 2010 (IP2010),respectively.A SAS software package was used in the statistical analysis.Results The results using CHP2010 and USP36,JP2011,EP7.0,and IP2010 had no significant difference (P=-0.7740).The results using CHP2010 of 1 748 samples showed that 132 samples (7.6%) required an additional step; nevertheless there was no such requirement when using the other pharmacopeias.The kappa value of two RJAs (CHP2010 and EP7.0) was 0.6900 (0.6297-0.7504) indicating that the CHP2010 and other pharmacopoeias have good consistency.Conclusions The results using CHP2010 and USP36,JP2011,EP7.0,and IP2010 have different characteristics.CHP2010 method shows a good performance in Specificity,mistake diagnostic rate,agreement rate,predictive value for suspicious rate,and predictive value for passed rate.The CHP2010 method only had disadvantages in sensitivity compared with other pharmacopeias.We suggest that the Chinese pharmacopoeia interference test be revised in accordance with the USP36,JP2011,EP7.0,and IP2010 judgment model.  相似文献
