With more and more attention and investment on acupuncture scientific researches, considerable outcomes and achievements has been acquired, but the shortcoming of low transformation rate of acupuncture research achievements is gradually exposed. Nowadays there is no related report on this problem, so based on achievement translational research in other areas and practical situation of acupuncture, the existing problems and solutions are analyzed. As a result, the existing problems include (1) the research content is mainly basic research and clinical research but less acupuncture device research, leading to limited transformation efficiency; (2) the evaluation system and transformation pattern are still needed to be perfect. The solutions are (1) to properly evaluate the research achievements of acupuncture, (2) to advocate the concept and method of translational medicine, (3) to reform the policy and system, and (4) to establish valid platforms covering research, outcomes and transformation.

Objective To explore protective effect of topiramate (TPM) and folic acid (FA) on mitochondrial damage in hippocampal CA3 neurons during pentylenetetrazol- induced kindling in immature rats.Methods Pentylenetetrazol (PTZ) - induced kindling in rats was used to establish rat models of epilepsy.Forty-eight 3-week-old male Wistar rats were randomly divided into 4 groups: two therapy groups with TPM 40 mg/(kg?d) or TPM 40 mg/(kg?d) and FA 5 mg/(kg?d) administration, 2 control groups (positive control group and negative control group) with the equal amount of distilled water administration. The seizure behaviors of rats were evaluated. Two months later, the rats were killed and the brain sections were made. The mitochondrial ultrastructures of neurons in hippocampal CA3 region were observed with transmission electron microscope.Results In the positive control group, the frequency of seizure was (48.4 ? 3.7)times, while in TPM group (44.3 ? 3.1)times and in TPM and FA group(40.8 ? 3 .7)times.The differences were significant among three groups (Pa

Objective To study the anti-fatigue effect of Cynomorium songaricum flavone(CSF)on old rats.Methods50 old male Wistar rats were randomly divided into the control group(no swimming,no drugs),single swimming group(swimming,given saline by gavage),and three swimming plus CSF groups(swimming,given CSF 20 g/kg weight,10 g/kg weight and 5 g/kg weight respectively),total five groups with 10 animals in each group.Animals swam with free swimming in endless cycles water 30 minutes once every day for 10 days.The level of monoamine oxidase(MAO) and glutathione peroxidase(GSH-px) in blood of animals were examined by MAO kit,GSH-px kit and ultraviolet spectrophotometer at 11th day.ResultsCompared with single swimming group,the body weights of swimming plus CSF groups increased significantly by 12.9%,80.6% and 200% respectively(P<0.01);swimming times before sinking increased by 19.4%,29% and 48.4%;sinking times of each rat(time/10 min) decreased by 17.8%,43.2% and 72.9%;total swimming times increased by 2.8%,7% and 29.6% respectively(P<0.01);MAO decreased by 60%,69.8% and 80.5%,GSH-px increased by 465.3%,563.8% and 635% respectively(P<0.01).ConclusionCSF shows anti-oxidative and anti-fatigue properties and can be given as prophylactic/therapeutic supplements for increasing antioxidant enzyme activities and preventing lipid peroxidation during strenuous exercise.

Purpose To examine the expression of Fascin-1 and β-catenin protein and K-ras gene mutation in colorectal adenocarcinoma, and to explore their role in progression of colorectal neoplasm and their relevance. Methods Fascin-1 and β-catenin were analyzed by use of immunohistochemistry En Vision two-step. K-ras gene mutation was detected by ARMS method.Relationship between overexpression of Fascin-1, the nuclear expression of β-catenin, and the mutations of K-ras gene and clinicopathologic parameters was analyzed, the correlation between them was also analyzed. Results In 112 colorectal adenocarcinoma samples, the overexpression rate of Fascin-1 protein was 27.7％ (31/112), significantly higher than non-neoplastic mucosa (P < 0.01). The high nuclear expression rate of β-catenin was 29.5％ (33/112) in adenocarcinoma and non-neoplastic mucosa respectively with a significant difference between two groups (P < 0.01). High expression rate of Fascin-1 protein and β-catenin were correlated significantly with lymph node metastasis (P = 0.022, P = 0.027), and TNM staging (P =0.042, P = 0.019) in colorectal adenocarcinoma. The overexpression of Fascin-1 protein was correlated with tumor location (P = 0.004). The mutation rate of K-ras gene was 34.8％ (39/112), which showed no correlation with age, gender, tumor size, grade of differentiation, lymph node metastasis and TNM staging (P> 0.05). There was a correlation between the overexpressison of Fascin-1 protein, the nuclear expression of β-catenin and the mutation of K-ras gene (rs= 0.252, rs= 0.258, P < 0.05). The overexpression of Fascin-1 protein positively correlated with the nuclear expression of β-catenin (rs= 0.213, P < 0.05). Conclusion Fascin-1 protein and β-catenin protein are involved in invasion and metastasis of colorectal cancer and are associated with K-ras gene mutation. K-ras may promote the overexpression of Fascin-1 by virtue of nuclear expression ofβ-catenin, which provided a new research direction on the treatment of K-ras gene mutated colorectal adenocarcinoma.

OBJECTIVETo study the neuroprotective effects of topiramate (TPM) alone or together with folic acid (FA) on young rats with kindling-induced epilepsy.

METHODSRat models of epilepsy were prepared by pentylenetetrazol (PTZ)-induced kindling. Seventy-two 3-week-old male Wistar rats were randomly divided into 6 groups: four TPM-treated epilepsy groups (TPM 20, 40 or 80 mg/kg/d and TPM 40 mg/kg/d + FA 5 mg/kg/d), a positive control group (untreated epilepsy group) and a negative control group (normal control group). After two months of administration, behaviors of the rats were recorded; serum levels of neuron-specific enolase (NSE) were measured using ELISA; pathological changes in the hippocampus were observed.

RESULTSThe frequency of convulsion seizures in the 20, 40 and 80 mg TPM treatment and TPM+FA groups was 44.7 +/- 2.9, 44.3 +/- 3.1, 42.7 +/- 3.2, and 40.8 +/- 3.7 respectively, which were significantly lower than that in the positive control group (48.4 +/- 3.7) (P <0.01). Twenty, forty and eighty mg TPM treatment and TPM+FA treatment significantly reduced NSE levels from 35.71 +/- 5.97 microg/L of the control group to 27.40+/- 6.40, 24.79 +/- 6.22, 21.47 +/- 6.87 and 22.55 +/- 7.02 microg/L respectively (P <0.05). Neuronal apoptosis in the CA3 and CA1 regions were alleviated in the four TPM treatment groups compared with positive control. The number of necrotic neurons was progressively reduced with the increased dose of TPM. The 40 mg TPM+FA treatment group showed less necrotic neurons in the CA3 and CA1 regions than the 40 mg TPM alone treatment group.

CONCLUSIONSTPM has protective effects against epilepsy-induced neuronal damage. The effect is dose-dependent. A combination of TPM and FA can produce a synergistic effect.

Objective To evaluate the clinical efficacy of Yiqi Fumai and Zixin Yangyin Prescription combined with Captopril for the treatment of children's hand-foot-mouth disease (HFMD) complicated with viral myocarditis (VMC); To explore the mechanism. Methods Totally 80 cases children with HFMD complicated with VMC were selected and randomly divided into two groups, with 40 cases in each group. Both groups were given conventional low flow oxygen, cardiac function monitoring, ribavirin antiviral, and fructose nutrition, and severe cases were given immune globulin and dexamethasone to relieve symptoms. The control group was given Captopril 0.5 mg/(kg?d), three times a day,orally,on the basis of conventional treatment,and the treatment group was given Yiqi Fumai and Zixin Yangyin Prescription on the basis of control group,one dose a day,decoction 180 mL,6 to 10 times a day,orally. The treatment in both groups lasted for two weeks. Serum hs-CRP, CK, CK-MB and cardiac function change before and after treatment of the two groups were observed. Electrocardiogram curative effect and comprehensive curative effect were evaluated. Results Compared with before treatment, the contents of hs-CRP, CK-MB, and CK in both groups decreased after treatment (P<0.05), and the treatment group was lower than the control group (P<0.05);Compared with before treatment, EF and FS in both groups increased after treatment, and A/E of mitral valve diastolic blood flow velocity peak decreased after treatment, with statistical significance among EF, FS and A/E between the two groups (P<0.05). The total effective rate of electrocardiogram was 92.5% (37/40) in the treatment group and 75.0% (30/40) in the control group, with statistical significance (Z=-2.370, P=0.018). The total effective rate of comprehensive efficacy was 92.5% (37/40) in the treatment group, and 77.5% (31/40) in the control group, with statistical significance (Z=-2.397, P=0.017). Conclusion Yiqi Fumai and Zixin Yangyin Prescription combined with Captopril can improve the clinical symptoms of HFMD complicated with VMC, improve clinical efficacy, whose mechanism may be related to the decrease of contents of hs-CRP, CK and CK-MB and enhancement of cardiac function.

Objective To explore the innuence of single-drug topirmate(TPM)on injured neurons of immature rats with chronic epilepsy. Methods A total of 72 male Wistar rats around 3-4 weeks of age were randomly allocated into 6 groups, 12 rats each. Group A: negative control group;group B:positive control group;group C:low-dose TPM group(20 mg/kg);group D:medium-dose TPM group(40 mg/kg);group E:high-dose TPM group(80 mg/kg);group F:united drug group[TPM 40 mg/kg+sodium valproate (VPA) 200 mg/kg]. Groups B-F belonged to the chronic epilepsy group,including rat models of epilepsy induced by intraperitoneal injection of pentylenetetrazol(PTZ)before the administration of TPM. After two-month administration, changes in body weight, behavioral performance,the level of serum neuron-specific enolase(NSE)and pathology in the hippocampus were examined. Results (1)The effect of group E on body weight of immature rats was significantly obvious than that of gruop B and gruop F.(2)Duration and degree of epileptic seizures induced by PTZ were respectively prolonged and alleviated in groups D and E. (3) NSE levels in groups administered with different doses of TPM were evidently lower than that in group B and there was no difference between group F and single-drug TPM groups.(4) Degenerative changes of hippocampal neurons and degree of glial cell hyperplasia were remarkably alleviated in group E. Conclusions TPM may alleviate the severity of neural injury following epileptic seizures in immature rats, with the existence of the dose effect;however,TPM plus VPA may impair its neuroprotective effects.
