Profiles of and correlation between objective and subjective outcome assessments following open-door laminoplasty for cervical spondylotic myelopathy

Background Open-door laminoplasty is widely used in the treatment of cervical spondylotic myelopathy （CSM）. This study aimed to investigate the profiles of and correlation between objective and subjective short-term outcome assessments after open-door laminoplasty for CSM. Methods We retrospectively analyzed surgical outcomes in 129 consecutive CSM patients who underwent open-door laminoplasty in Peking University Third Hospital from February 2008 to November 2011. Both objective and subjective assessments were evaluated before surgery, 3 months after surgery, and 1 year after surgery. We then analyzed the profiles of and correlation between objective and subjective short-term outcomes. Results The Modified Japanese Orthopaedic Association （mJOA） score was significantly improved at 3 months （P〈0.01） and 1 year （P〈0.01） after surgery. Bivariate Logistic regression showed that sensory improvement contributed more to the recovery rate than motor function improvement at 3 months after surgery, while motor function contributed more to the recovery rate at 1 year after surgery. On the subjective assessment （the short form （SF）-36）, there was no significant improvement at 3 months after surgery （P〉0.05）, while physical function （PF）, role-physical （RP）, and social function （SF） were notably improved at 1 year after surgery （P〈0.01）. Improved mJOA score correlated with improvements in PF, RP, bodily pain, general health （GH）, vitality （VT）, and SF （P〈0.05） at 3 months after surgery; PF, GH, VT, and SF were associated with improved mJOA scores at 1 year after surgery. Conclusions Patients benefit from surgery by postoperative restitution of neurological function with early recovery of sensory function, followed by a gradual transition to motor function improvement. At the early stage of recovery, improvement in the mJOA score essentially correlated with improvements in the physical domains of the SF-36, while at the later stage, mJOA score improvement was a     

补肾活血方对PCOS大鼠模型卵巢中PAI-1mRNA表达的影响

目的探讨补肾活血方对大鼠PCOS模型卵巢局部纤溶酶原激活物抑制因子-1（PAI—1mRNA）表达的影响。方法选用未成年24d龄SD雌性大鼠60只,随机分为模型组、克罗米酚组、补肾活血方高剂量组、补肾活血方低剂量组、正常对照组5组。用Bogovich法建立大鼠多囊卵巢病理模型。以克罗米酚为对照。用原位杂交法观察补肾活血方对多囊卵巢大鼠局部PAI—1mRNA的影响。结果模型组卵巢局部PAI—1mRNA存在卵泡膜间质细胞显著增高,用补肾活血方高、低剂量与克罗米酚药后,卵巢局部PAI-1mRNA的表达明显降低．差异具有统计学意义（P〈0．05、P〈0．01）。补肾活血方高剂量组与克罗米酚组比较,差异具有显著统计学意义（P〈0．01）;低荆量组与克罗米酚组比较差异无统计学意义（P〉0．05）,补肾活血方高、低剂量组比较,低剂量组卵泡膜间质细胞上PAI-1的基因表达增高更明显,但二者差异无统计学意义（P〉0．05）。结论PAI-1mRNA可能与多囊卵巢综合征的发病机制有关。以补肾活血立法的补肾活血方能降低多囊卵巢大鼠局部PAI—1mRNA的显著增高表达．降低PAI—1mRNA卵巢局部的作用。提示补肾活血方可能通过PAI—1mRNA途径促进卵巢排卵的机制。     

Sphingosine Kinase-1/sphingosine 1-phosphate pathway in diabetic nephropathy

Objective Diabetic nephropathy （DN） is the major cause of end-stage renal disease worldwide and its prevalence continues to increase.Currently,therapies for DN provide only partial renoprotection; hence new targets for therapeutic intervention need to be identified.In this review,we summarized the new target,sphingosine kinase-1/sphingosine 1-phosphate （SphK1/S1P） pathway,explored its potential therapeutic role in the prevention and treatment of DN.Data sources Most relevant articles were mainly identified by searching PubMed in English.Study selection Mainly original articles and critical review articles by major pioneer investigators in this field were selected to be reviewed.Results SphK1/S1P pathway can be activated by hyperglycemia,advanced glycation end products,and many proinflammatory cytokines,which leads to fibronectin,transforming growth factor-31 up-regulation and AP-1 activation.And then it could promote glomerular mesangial cells proliferation and extracellular matrix accumulation,mediating the initiation and progression of diabetic renal fibrosis.Conclusions SphK1/S1P pathway is closely correlated with the pathogenesis of DN.The results suggest that SphK1/ S1P pathway as a new target for clinically improving DN in future is of great prospect.

Depressant effect and mechanism of atorvastatin on the chronic rejection of aortic allograft in rats

Objective To investigate the depressant effect and mechanism of atorvastatin on the chronic rejection of aortic allograft in rats. Methods： The models of abdominal aorta transplantation were made with micro-surgery in rats. The recipients were divided into three groups： allograft control group, atorvastatin-treated group and isograft control group. Vascular intimal thickness in all of the groups were observed by histological examination. The expression of PCNA and α-SMA were determined by immunohistochemistry. The content of nitric oxide was determined by nitrate reductase chromatometry. Results： The vascular intimal thickness in rats of atorvastatin-treated group （11.60% ± 2.40% ） were lower than those in allograft control group （34.60 % ± 6.40 % ; P 〈 0.05） and higher than those in isograft control group （1.15 % ± 0.65 %; P〈 0.05 ）. The expression level of PCNA was decreased in atorvastatin-treated group （4.80% ± 0.80% ） than allograft control group （18.40% ± 1.80% ; P〈0.05） and higher than isograft group （1.20% ± 0.40% ; P〈0.05）. Conclusion： The expression of PCNA in the transplant aorta could be suppressed by atorvastatin, which resalted in relief of chronic rejection of aortic allograft.     

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。     

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

Association between interferon gamma receptor 1 -56C/T gene polymorphism and tuberculosis susceptibility: a meta-analysis

Background Genetic variations in the interferon-gamma （IFN-γ） receptor 1 gene （IFNGR1） may contribute to tuberculosis （TB） risk in different populations.Many studies have investigated the relationship between IFNGR1 56C/T polymorphism and the susceptibility to TB,but have yielded conflicting results.A comprehensive meta-analysis is needed to provide a more accurate estimation of the relationship between them.Methods A literature search based on a combination of manual and computer-based methods was conducted on four English databases （PubMed,Science Direct,SpringerLink,and EBSCO） and three Chinese databases （Wanfang,CQVIP,and Chinese National Knowledge Infrastructure databases）.Pooled odds ratios （ORs） and 95％ confidence intervals （95％ Cls） were calculated using either the fixed-effects model or the random-effects model for different genetic models based on the heterogeneity examination.Results A total of six studies comprising 1 497 confirmed TB cases and 1 802 controls were included in this meta-analysis.Overall,no significant association was observed between IFNGR1-56C/T polymorphism and TB susceptibility （C vs.T,OR=0.90,95％ Cl 0.69-1.17; CC vs.TT,OR=0.87,95％ Cl 0.65-1.18; TC vs.TT,OR=-1.031,95％ Cl 0.872-1.219; CC＋TC vs.TT,OR=0.89,95％ Cl 0.64-1.26; CC vs.TC＋TT,OR=0.92,95％ Cl 0.66-1.29）.In subgroup analysis,a significant association was found in the dominant model （CC＋TC vs.TT,OR=1.24,95％ Cl 1.02-1.51） in Africans,but not in Asians or Caucasians.Conclusions Our meta-analysis did not provide enough powerful evidence to identify a significant association between IFNGR1-56C/T polymorphism and TB susceptibility in the overall population.In subgroup analysis,it indicates that IFNGR1-56C/T is possibly associated with increased TB risk in Africans,but not in Asians or Caucasians.However,larger sample size and better-designed case-control studies are needed to validate these findings.     

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.     

Effect of behavior training on learning,memory and the expression of NR2B,GluR1 in hippocampus of rats offspring with fetal growth restriction

Objective： To study effects of behavior training on learning, memory and the expression of NR2B, GluR1 in hippocampus of rat＇ s offspring with fetal growth restriction（FGR）. Methods： The rat model of FGR was established by passive smoking method. The rats offspring were divided into the FGR group and the control group, then randomly divided into the trained and untrained group, respectively. Morris water maze test was proceeded on postnatal month（PM2/4） as a behavior training method, then the learning-memory of rats was detected through dark-avoidance and step-down tests. The expressions of NR2B and GluR1 subunits in hippocampal CA1 and CA3 areas were detected by immunohistochemical method. Results： In the dark-avoidance and step-down tests, the performance record of rats with FGR was worse than that of control rats, and the behavior-trained rats was better than the untrained rats, when the FGR model and training factors were analyzed singly. The model factor and training factor had significant interaction（P 〈 0.05）. The expressions of NR2B and GluR1 subunits in hippocampal CA1 and CA3 areas of rats with FGR reduced. In contrast, the expressions of GluR1 and NR2B subunits in CA1 area of behavior-trained rats increased, when the FGR model and training factors were analyzed singly. Conclusion： These findings suggested that the effect of behavior training on the expressions of NR2B and GluR1 subunits in CA1 area should be the mechanistic basis for the training-induced improvement in learning-memory abilities.     

Glutamate Transporter 1-mediated Antidepressant-like Effect in a Rat Model of Chronic Unpredictable Stress

In recent years, more attention has been paid to the role of the glutamate transporter 1 （GLT-1, EAAT2） in major depressive disorder （MDD）. However, experimental data on brain GLT-1 levels are, to some extent, inconsistent in human postmortem and animal studies, These discrepancies imply that the role of GLT-1 in the pathophysiology of MDD and the action of antidepressants remain obscure. This work was designed to study the impact of chronic unpredictable stress （CUS） for 2 ses- sions per day for 35 days and four weeks of fluoxetine （FLX） on depressive-like behaviors in rats, as well as the concomitant expression of the GLT-1 protein in the hippocampus. Behavioral changes were assessed by the sucrose preference and open field tests. GLT-1 levels were detected by immunohisto- chemistry and Western blot analysis. Our study demonstrated that the animals exposed to CUS showed depressive-like behaviors and exhibited a significant decrease in GLT-1 expression in the hippocampus. Chronic FLX treatment reversed the behavioral deficits and the CUS-induced decrease in GLT-1 levels. Taken together, our results support the reduction of GLT-1 in human postmortem studies in MDD and suggest that GLT-1 may be involved in the antidepressant activity of FLX. Our studies further support the notion that GLT-1 is an attractive candidate molecule associated with the fundamental processes of MDD and may be a potential, and novel pharmacological target for the treatment of MDD.

Iloprost inhibits fracture repair in rats

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.     

Bias in multiple-treatments meta-analysis: a case on comparative efficacy and tolerability of 15 antipsychotic drugs for schizophrenia

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.

Low-intensity aerobic exercise training attenuates airway inflammation and remodeling in a rat model of steroid-resistant asthma

Background Aerobic exercise can improve symptoms,reduce airway inflammation,and even ameliorate airway remodeling in asthmatic animals and patients.However,previous studies have focused mainly on the effect of aerobic exercise on steroid-sensitive asthma （SSA）.The goals of this study were to determine the effect of low-intensity aerobic exercise training on airway hyperresponsiveness,inflammation,and remodeling in a rat model of steroid-resistant asthma （SRA） and to identify the potential mechanisms underlying these effects.Methods Endotoxin-free ovalbumin with or without lipopolysaccharide were applied to establish rat models of SRA and SSA,respectively.Airway hyperresponsiveness,inflammation,remodeling,expression of interleukin （IL）-25,IL-33,thymic stromal lymphopoietin （TSLP）,high mobility group box-1 （HMGB1）,and IL-17 in bronchoalveolar lavage fluid （BALF）,and the role of dexamethasone （DXM） were compared between these two asthmatic rat models.The effect of low-intensity aerobic exercise training and anti-HMGB1 treatment on airway hyperresponsiveness,inflammation,and remodeling in SRA rats also was evaluated.Results SRA rats developed neutrophil-dominated airway inflammation （（29.5±4.1）％ of the total cell numbers in BALF）,whereas SSA rats developed eosinophil-dominated airway inflammation （（24.0±6.1）％ of the total cell numbers in BALF）.Compared with SSA rats,SRA rats had more severe airway hyperresponsiveness,lower levels of IL-25 （（33.6±10.3） vs.（104.8±24.9） pg/ml）,IL-33 （（87.5±25.0） vs.（226.6±40.7） pg/ml）,and TSLP （（1 933.2±899.5） vs.（7 224.0±992.1） pg/ml）,and higher levels of HMGB1 （（21.2±4.5） vs.（5.4±1.6） ng/ml） and IL-17 （（780.5±261.7） vs.（291.4±76.4） pg/ml） in BALF （all P ＜0.05）.However,there was no significant difference in goblet cell hyperplasia,subepithelial collagen thickness,and airway smooth muscle remodeling between the two groups.Compared with control SSA rats,airway hyp
