OBJECTIVE:To study the effect of Shenfu injection(SFI)on the expression profile of myocardial miRNA in rats with chronic congestive heart failure (referring to heart failure). METHODS:40 rats were randomly divided into sham operation group (normal saline,ip),model group (normal saline,ip),valsartan group (positive control,10 mg/kg,ig) and SFI group (0.75 mL/kg,im),10 in each group. Except for sham operation group,another groups were reduced heart failure. After modeling, rats in other groups received related medicines,once a day. Affymetrix miRNA V4.0 chip technology was conducted to analyze the miRNA expression in myocardial tissue of rats with heart failure after administration for 28 d,and screen the miRNA on common differential expression in myocardial tissue of rats in each group. The miRNA associated with heart failure was analyzed by thresh-old of differential gene expression multiple value greater than or equal to 1.1. Gene Ontology (GO) analysis was used to analyze functional classification and biological signaling pathway of differentially expressed genes. RESULTS:There were totally 29 miR-Nas on common differential expression and 7 miRNAs associated with heart failure (rno-miR-30c-1-3p, rno-miR-125b-5p, rno-miR-133a-5p,rno-miR-199a-5p,rno-miR-221-3p,rno-miR-146a-5p and rno-miR-1-3p). SFI can significantly downregulate the expressions of rno-miR-125b-5p,rno-miR-133a-5p,rno-miR-221-3p,rno-miR-1-3p in myocardial tissue of rats (P<0.05 or P<0.01). Results of GO analysis showed,miRNAs on differential expression were mainly related to signal transduction,cytoplasm and nucleotide binding. CONCLUSIONS:SFI plays the role of anti-heart failure by participating in the downregulation of miRNAs associated with heart failure process and then affecting related signal pathways transduction after the combination of cyto-plasm and nucleotide.

ObjectiveTo observe the curative effect of alprostadil combined with cilostazol in treatment of patients with lower limb atherosclerosis.MethodsSixty-two patients with lower limb atherosclerosis were divided into cilostazol group (cilostazol 100 mg,2 times a day,oral) and therapeutic alliance group (cilostazol 100 mg,2 times a day,oral; alprostadil 10 μ g dissolved in 100 ml intravenous infusion of 0.9％ sodium chloride,once a day) by random number table with 31 cases each.The changes of ankle-brachial index (ABI),distance of 6-minute walk test(6-MWT) and the dorsal blood flow were compared before and after treatment.Results | After treatment,the distance of 6-MWT,ABI and the level of dorsal blood flow were significantly improved in two groups (P ＜ 0.05 or ＜ 0.01 ).Distance of 6-MWT and the level of dorsal blood flow in therapeutic alliance group was significantly higher than that in cilostazol group after treatment [(425.4±138.5) m vs.(379.5±124.6) m,(0.77±0.18) ml/ (s·cm2) vs.(0.66±0.14) ml/( s· cm2)] ( P＜0.05 ).The total effective rate in the treatment of cold feel in therapeutic alliance group was significantly higher than that in cilostazol group [ 87.5％(21/24) vs.61.9％( 13/21 ) ](P＜ 0.05).Conclusion Alprostadil combined with cilostazol is safe and effective in treating lower limb atherosclerosis.

Domestic injections took the lead among all the anti-vomiting drugs. CONCLUSION: Consumption quantity of 5-HT3 antagonists has a rapid increase and which occupy a dominate place in our hospital.

Objective To determine the difference of microvessel density(MVD) in each layer and region of abdominal flap. MethodsFlaps were obtained from 60 patients with abdominal operations,10 in each of the regions from I to VI.The vascular endothelial cells were marked with CD34 by immunohistochemistry,and the MVD in each region and layer of the abdominal flaps was determined.Results The vascular net of abdominal flap was divided into five layers: papillary layer of corium,papillary underlayer of corium,papillary deep layer of corium,superficial fascia and deep fascia.The mean MVD of the five layers were 17.80?1.68,9.12?1.84,27.91?2.44,37.18?6.55 and 46.91?7.02,respectively,with significant differences among them(P0.05).Conclusion Anatomic factors may be responsible for the survival of large abdominal flaps.Either of the direct and retrograde motion is feasible in the transplantation.

? AIM: To investigate the differences between synoptophore and triple prism strabismometry and its possible cause.?METHODS: There were 347 patients with horizontal concomitant strabismus involved, in which 76 patients were esotropia, 37 patients were male while 39 were female, with average age of 13. 27 ± 7. 77 years old. There were 271 patients with exotropia, 131 cases were male while 140 were female, with average age of 15. 43 ± 8. 42 years old. All the patients were examined by synoptophore and prism plus shaded strabismometry in a long distance of 6m. Datas were analyzed by SPSS 17. 0.?RESULTS:In the exotropia patients, the conversions of circular degree(°) and prism degree(△) were:1°=0. 29△ ~1. 78△, which was statistically significant with intermittent strabismus (P=0. 001). While in the esotropia patients, the conversions were:1°=2. 01△ ~2. 15△.?CONCLUSION: The diversity between the two methods is enlarged with the increase of squint angle for exotropia patients. While in esotropia patients, the diversity decreased with the increase of squint angle. Synoptophore equipped with +7. 00D, defects of the triple prism itself and proximal convergence during exam may be the reasons for the diversity.

OBJECTIVE: To explore the relationship of the local recurrence with the expression of protein Survivin and MMP-2 in the primary lesions and the surgical margins of laryngeal carcinoma. METHOD: The primary lesions and the surgical margins of laryngeal carcinoma of 48 patients were made into serial sections. Immunochemical methods was used to detect the expression of protein Survivin and MMP-2 in the primary lesion and the surgical margins of laryngeal carcinoma of 48 patients. RESULT: The positive expression for Survivin and MMP-2 in the primary lesion was 70.83% (34/48) and 66.67% (32/48) respectively, and the positive expression of Survivin and MMP-2 in the surgical margins of laryngeal carcinoma was 47.92% (23/48) and 37.50% (18/48), which in the primary lesion was significantly higher than those of the surgical margins of laryngeal carcinoma (P < 0.05). The recurrence rates of primary lesion positive for Survivin (34 cases) and MMP-2 (32 cases) were 26.47% (9/34) and 25.00% (8/32), which were higher than negative for them 7.14%(1/14) and 12.50% (2/16) (P > 0.05). The recurrence rates of those with Survivin (23 cases) and MMP-2 (18 cases) positive surgical margins were 34.78% (8/23) and 38.89% (7/18) respectively, which were significantly higher than those with negative ones 8.00% (2/25) and 10.00% (3/30) (P < 0.05). Logistic analysis showed that the expression of Survivin and MMP-2 protein in the surgical margins of laryngeal carcinoma was positively associated with the recurrence rates. CONCLUSION Laryngeal carcinoma patients with Survivin-positive or MMP-2-positive margin would have a higher recurrence rate. Survivin and MMP-2 protein can be used as biomarkers for local recurrence of laryngeal carcinoma after operation.
