The formation of carcinomas of liver, lung and kidney in rats by feeding aminopyrine (AP) plus sodium nitrite (Na NO2) in diet was investigated. 72 young Wister rats were divided into A,B,C,D group. Group A was set as control receiving basal diet and tap water. Another 3 groups were given basal diet containing AP plus Na NO2 (2g/kg each). However, group B was given tap water, group C ascorbic acid solution, group D sea buckthorn (Hippophae rhamnoides L.) juice for drinking. After 38 week's feeding, group B developed tumors in the livers (17/17), lungs (6/17) and kidneys (4/17) and the average life-span was 195 days, group D delayed the development of tumors and the average life-span was 270 days, significantly longer than that of group B (195 days, p

Objective To compare the clinical value of fluid attenuated inversion recovery imaging (FLAIR),magnetic resonance diffusion-weighted imaging(DWI) and magnetic resonance angiography(MRA) in diagnosis of early cerebral infarction.Methods 70 cerebral infarction patients were chosen.They underwent FLAIR,DWI and MRA examination.Results 70 patients with early cerebral infarction mostly were multiple lessions accouting for 60％.Supper actue period had 22 cases and acute period had 48 cases.DWI had the highest detection rate of cerebral infarction,particularly in the hyperacute period the detection rate reached 100％,which was significantly higher than the FLAIR and MRA(x2 =12.4,P ＜ 0.05).Conclusion Especially in the early diagnosis of hyperacute cerebral infarction,DWI is superior to FLAIR and MRA.FLAIR showed better on the cortex and periventricular lesions,MRA can check out the blood vessel lesions in the infarction area.

A total of 104 marine bacterial strains were isolated from Stelletta tennui around Sanya area of South China Sea by dilution-plate method and were screened for anti-microbial activity on Escherichia coli, Staphylococcus aureu, Pseudomonas fluorescens, Bacillus subtilis, Aspergillus niger, Candida albicans and Pacecilomyces variotii by agar diffusion, paper disc diffusion assay and cell concentration counts methods. It was found that 23 strains, which are 22.2% of the total isolated strains, have anti-microbial activities. Among the 23 strains, A05, A08, A72 and A75 were morphologically, physiologically and biochemically characterized and identified to be the genus Bacillus. At the same time, it was proved that there are positive and negative synergistic effects between or among active strains, e.g., as for A72-75 combination, an obvious enhanced anti-microbial activities on inhibiting Candida albicans and Pseudomomas fluorescens growth was observed than A72 or A75.

OBJECTIVE:To systematically review the clinical efficacy and safety of sirolimus(SRL)versus tacrolimus(Tac) for anti-rejection after renal transplantation,and provide evidence-based reference for clinical treatment. METHODS:Retrieved from PubMed,EMBase,Medline,Science Direct,Cochrane library,CJFD,VIP and Wanfang Database,randomized controlled tri-als(RCT)about SRL(test group)versus Tac(control group)for anti-rejection after renal transplantation were collected. Meta-anal-ysis was performed by using RevMan 5.2 software after data extraction and quality evaluation. RESULTS:Totally 5 RCTs were in-cluded,involving 594 patients. Results of Meta-analysis showed,there was no significant difference in the incidence of acute rejec-tions [RR=1.26,95%CI(0.82,1.93),P=0.30],graft loss rate [RR=0.91,95%CI(0.32,2.55),P=0.85] and mortality rate [RR=0.87,95%CI(0.34,2.22),P=0.77] in 2 groups;while the infection rate in test group was significantly lower than control group, the difference was statistically significant [RR=0.13,95%CI(0.04,0.40),P<0.001]. CONCLUSIONS:Compared with Tac,SRL has the same anti-rejection effect after renal transplantation,not changed graft loss rate and mortality rate,but reduced the infection rate with higher safety.

Limb-shaking transient ischemic attack (TIA), a rare manifestation, is commonly caused by severe stenosis or occlusion of an extracranial internal carotid artery. Such patients are usually treated with surgical revascularization or anti-platelet therapy. We present a 56-year-old woman with 6 months’ episodic attacks starting with mouth skewed to the right and a sensation of ‘weakness’ involving predominantly her left arm, and at times, also involved the left leg. This was immediately followed by rhythmic jerky movements of the left arm and at times, also involved the left leg. Magnetic resonance angiography revealed severe stenosis of M1 segment of the right middle cerebral artery. The patient’s symptoms were signifi cantly improved by treatment with anti-platelet drugs and nimodipine.

Objective To investigate the expression of Fascin-1 protein in colorectal adenocarcinoma,and the relationship with its clinicopathologic features.Methods The expressions of Fascin-1 protein in colorectal adenocarcinoma tissues of 60 cases,colorectal adenoma tissues of 30 cases and normal mucosa tissues (4 cm distance to neoplasm) of 30 cases were detected by Microwave-EliVisionTM immunohistochemistry method,and the relationship between the expression of Fascin-1 protein in colorectal adenocarcinoma tissues and its clinicopathologic characteristics was analyzed.Results The expression of Fascin-1 protein was located in cytoplasm.The positive expression rates of Facsin-1 protein were 3.3% (1/30),30.0% (9/30) and 53.3% (32/60) in normal mucosa tissues,colorectal adenoma tissues and colorectal adenocarcinoma tissues,respectively.The expression of Fascin-1 was gradually increased in these three tissues,and there was statistical difference among the three tissues (P0.05).Conclusion The high expression of Fascin-1 protein is correlated to high invasion ability and lymph node metastasis,which can play as a sensitive index in predicting the invasion and metastasis of colorectal adenocarcinoma.

Objective:To study influencing factors for in‐stent restenosis (ISR) during one year in patients with coro‐nary heart disease (CHD) after coronary sirolimus‐eluting stent (SES) implantation .Methods :According to results of coronary angiography (CAG) ,a total of 275 patients ,who hospitalized in our department from Jan 1st ,2012 to Dec 30th ,2013 and have received SES implantation and reviewed CAG after one year ,were divided into non‐ ISR group (n=247) and ISR group (n=38) .Clinical characteristics were compared between two groups ,and Logistic regression analysis was used to analyze influencing factors for ISR .Results:Compared with non‐ISR group ,there were significant rise in percentages of occlusion lesions (17. 9% vs .31. 9% ) ,multiple overlapping stents (16. 7% vs . 31.9% ) ,and significant reduction in percentage of stent post‐dilatation (34.9% vs .10.6% ) in ISR group ,P<0.05 or <0. 01 ;Logistic regression analysis indicated that coronary occlusion lesion was a risk factor (OR :2. 855 ,95%CI :1.197~6.808 ,P=0.018) ,and post‐dilatation was a protective factor (OR :0.198 ,95% CI :0.057~0.691 , P=0.011) for ISR occurrence .Conclusion:Multiple overlapping stents and coronary occlusion lesions increase one‐year in‐stent restenosis rate ;stent post‐dilatation can reduce one‐year in‐stent restenosis rate ;coronary occlusion le‐sions is a risk factor , and stent post‐dilatation is a protective factor for restenosis during one‐year after coronary drug‐eluting stent implantation .

BACKGROUND:It is suggested that glucose metabolism of frontal lobes,cingulate gyri and caudate nuclei in cerebral functional area of patients with depression is low,and the blood flow in cerebellum decreases.OBJECTIVE:To observe the effect of scalp acupuncture on cerebral glucose metabolism in depression by positron emission tomography.DESIGN:Randomly controlled and verifying experiment.SETTING:Department of Acupuncture and Aoxibustion in Nanfang Hospital and Center of Positron Emission Tomography in a Guangdong People's hospital.PARTICIPANTS:Twelve patients of primary depression,from Nanfang Hospital,Zhujiang Hospital and Center of Positron Emission Tomography in Guangdong People's Hospital from October 2002 to October 2003,were selected randomly with the diagnostic criteria of [F32] in the Third Edition of the Chinese Classification and Diagnostic Criteria of Mental Disease.Among them,3 were male and 9 were female.Their ages were from 36 to 66 years,with the average of 48.METHODS:Giving scalp acupuncture in middle line of vertex(MS5),middle line of forehead(MS1) and bilateral lateral line 1 of forehead(MS2).All the patients received positron emission tomography examination before and after acupuncture treatment for 6 weeks.Then cerebral Regions of Interest,bilateral frontal lobes,bilateral caudate nuclei,bilateral cingulate gyri and bilateral cerebella,were chosen and their average glucose metabolisms were counted by half-quantifying analysis.MAIN OUTCOME MEASURES:Glucose metabolism of bilateral frontal lobes,bilateral caudate nuclei,bilateral cingulate gyri and bilateral cerebella.RESULTS:According to intension,all 12 patients with primary depression sults of right frontal lobes(2.91 ±0.34),left frontal lobes(2.96±0.26),right cingulate gyri(2.68±0.20),right caudate nuclei (2.61±0.39) and left cerebellum(2.55±0.18)were obviously higher than those of right frontal lobes(2.53±0.31),left frontal lobes(2.53±0.36),right cingulate gyri(2.34±0.31),right caudate nuclei(2.40±0.33) and left cerebellum(2.35±0.25)before treatment(P＜ 0.05-0.01).However, the results of left cingulate gyri (2.69 ±0.38),left caudate nuclei(2.66±0.01) and right cerebellum(2.50±0.27) were similar to those of left cingulate gyri(2.43±0.38),left caudate nuclei(2.45±0.21) and right cerebellum(2.30±0.34) before treatment(P ＞ 0.05).CONCLUSION:Scalp acupuncture on middle line of vertex,middle line of forehead and bilateral lateral line 1 of forehead could improve the glucose metabolism in depressive patients of certain cerebral regions,and it might be a mechanism related to improvement of frontal lobes,caudate nuclei,cingulate gyri and cerebellum.
