Objective To study the effect of chemically synthesized Nogo-66 receptor ( NgR ) specific small interfering RNA ( siRNA) on nerve regeneration and function of newborn rats after hypoxic-ischemic brain damage ( HIBD) . Methods A total of 50 HIBD newborn rats were set up. They were randomly assigned OR allocated into siNgR group ( n=20 ) , normal saline ( NS ) group ( n=20 ) and HIBD group ( n=10 ) . The rats of siNgR group were given intraventricular injection of siNgR and transfection reagents ( 10μl ); the rats of NS group were given intraventricular injection of NS and transfection reagents (10μl);and the rats of HIBD group had no intervention. In addition to these three groups, there is another group, sham-operated group ( n=10 ) . The rats of sham-operated group were sham-operated ( common carotid artery was isolated but not ligated) and did not receive hypoxia-ischemia processing and intraventricular injection. Utilize water maze experiment to analyze the rats' escape time. The levels of NgR and GAP-43 protein in rats' brains were measured by immunohistochemistry and image analysis. Results RT-PCR gel electrophoresis results showed that the NgR cDNA stripe of siNgR group was not obvious, but the stripe of NS group was clear. At the same time, the GAPHD cDNA bands of the above two groups were both clear. There were more NgR positive immune reaction products ( brown particles) in NS group than in siNgR group. The number of GAP-43 positive cells by immunohistochemistry in sham-operated group, HIBD group, NS group and siNgR group was (33. 24±1. 32), (20. 14±1. 24), (18. 73±1. 41) and (28. 06±1. 78), respectively. The number of sham-operated group and siNgR group was greater than HIBD group and NS group ( P＜0. 05 ) . There was no statistical significant difference for the number of GAP-43 positive cells between sham-operated group and siNgR group ( P＞0. 05 ) . Water maze experiment results showed that the newborn rats ' average escape time ( s ) of HIBD group ( 58. 1 ± 10. 3,47. 2±10. 1, 42. 5±7. 6) was obviously longer than sham-operated group (34. 2±5. 6, 25. 7±6. 2, 21. 2±8. 1), and the difference was statistically significant (P＜0. 05). However, the average escape time of siNgR group (37. 5±9. 8, 29. 1±9. 8, 27. 2±9. 3) was obviously shorter than HIBD group and NS group (60. 7±5. 2, 49. 1±9. 9, 45. 3±9. 3), (P＜0. 05). Conclusions Chemically synthesized specific siRNA had the potential to interference the expression of NgR in the brain of newborn rats, and to a certain extent, could promote the nerve regeneration and neural functional recovery of rats.

Objective To explore the expressions of transforming growth factor(TGF)-?1 and connective tissue growth factor(CTGF) in viral myocarditis(VM) and the intervention effect of valsarta on them.Methods Fifty-four male Balb/c mice were randomly divided into 3 groups:control group,treatment group and model group.Model group and treatment group established VM model by intraperitoned injecting 0.1 ml CVB3.They were killed on days 7,14 and 28,respectively.Histological cross sections of heart were stained with hematoxylin-eosin and myocardial histopathplogic scores were counted under optical microscope.The expressions of typeⅠand Ⅲ myocardial collagen,TGF-?1 and CTGF were examined by immunohistochemical method and analyzed by using SPSS 11.5 software.Results Compared with control group,histopathplogic scores,the expressions of type Ⅰand Ⅲ myocardial collagen,TGF-?1 and CTGF increased markedly in model group (Pa

Smoking and exposure to second hand smoke are the deadly killer of human health. Tobacco kills more than one million people each year in China. According to 2015 Chinese adult tobacco survey, the number of smokers in China increased by 15 million during five years, from 301 million in 2010 to 316 million in 2015. Smoking addiction is a chronic recurrent disease, and its pathogenesis is associated with the mesolimbic dopamine system. In recent years, domestic and overseas scholars studied the brain function of smoking addicts through resting state functional magnetic resonance imaging (fMRI), and found that the brain functional activity of smoking addicts has changed. fMRI can help us understand the mechanism of tobacco dependence, and provide the evidence of diagnosis, treatment and health management of tobacco dependence. In this paper, the present study situation and the application in the field of the treatment and management of smoking cessation of fMRI in smoking addicts are reviewed.

Objective To make a further recongnizing of the manifestations of diffuse axonal injury (DAI)on CT images for the early accurate clinical diagnosis.Methods The CT image data and its correlated clinic features of 56 cases with diffuse axonal injury(44 male,12 female)were analyzed retrospectively.In this series,43 cases were caused by traffic accident,13 by falling from high place.Results 1. 44 cases had haemorrhage lesions(less than 2 cm in diameter)in brain parenchyma which were at the corticomedullary junction,corpus callosum,brain stem,basal ganglia,internal capsule.2. 41 cases had subarachnoid and/or intraventricular hemorrhage 3. 9 cases had acute generalized brain swelling 4. 5 cases were associated with epidural hematoma and 16 with subdural hematoma.Conclusion CT manifestation of DAI have some featrues,and can provide reliable evidence for accurate clinic diagnosis of DAI.

Objective To observe the effects of chemo-endocrine therapy on gastric carcinoma (GC). Methods Cancerous tissues from 95 patients with primary GC were examined for the presence of estrogen receptor (ER) and progesterone receptor (PgR). Afterwards, 64 GC patients with recurrent or metastatic conditions were randomly divided into two groups: chemotherapy group and chemo-endocrine therapy group. Results A total of 34.38% ER positive and 16.30% PgR positive rates were found. For ER positive patients, the use of tamoxifen-EAP regimens was more effective than that of EAP alone (P

Objective To evaluate the clinical efficacy ofDuhuo Jisheng Decoction in treating liver and kidney deficiency syndrome of knee osteoarthritis (KOA) by ultrasound.Methods A total of 120 cases of KOA patients with liver and kidney deficiency syndrome were randomly divided into two groups (each contains 60 cases). Control group took hydrochloric acid glucosamine capsules, while treatment group tookDuhuo Jisheng Decoction additionally for 8 weeks. ESR, CRP, WOMAC, joint swelling scores, and TCM syndrome scores of the two groups were determined, and the sonographic characteristics of knee-joint effusion in patellar fabricius, synovial membrane, cartilage and bone erosions were compared before and after treatment.Results There were significant differences in ESR, CRP, WOMAC, joint swelling scores, and TCM syndrome scores between before and after treatment in both groups (P<0.05,P<0.01). The knee-joint synovial membrane got thinner after therapy in osteoarthritis patients, and the effusion in knee-joint also decreased. The vessel flow signals in knee-joint synovial membrane of osteoarthritis decreased after drug therapy (P<0.05,P<0.01).ConclusionDuhuo Jisheng Decoction can improve clinical efficacy of KOA with liver and kidney deficiency syndrome. Ultrasound can clearly observe the changes of effusion in patellar fabricius, and synovial membrane, and can provide good imaging assessment for the drug therapy for KOA patients.

Objective To study the relationship between salt consumption and hypertension in Chinese people,and provide basic information for developing intervention strategies.Method The data of 45 349 chinese residents aged 15 yrs and above from 2002 China National Nutrition and Health Survey was used.Results The hypertension prevalence was 18.2%.The prevalence of residents with high blood pressure value was 36.0%,which was 20.4% and 16.2% among men and women,respectively. Hypertension prevalence among people living in urban was higher than their counterparts living in rural.The prevalence of hypertension increased with salt consumption.As compared to people who consumed less than 6 g salt per day,after relative confounding factors adjusted,the prevalence ratio was 1.09,1.14 and 1.28 times,respectively,among people who averagely consumed 6～12 g,12218 g,and≥18 g salt per day,which was 1.13,1.11 and 1.30 times,respectively,among employment population.Conclusion The hypertension prevalence of chinese residents is quite high.There is significant relationship between salt consumption and hypertension.It is very important to strengthen the health education for preventing and controlling hypertension in Chinese residents.
