The incidence of adverse cardiovascular events was 19.3% in group A, which was significantly higher than that in group B (χ2 =2.193,P<0.05). There was no significant difference in the incidence of bleeding between the two groups.Conclusion The use of STEMI patients underwent PCI surgery ticagrelor treatment, in case of the risk of bleeding can effectively improve the patient's myocardial reperfusion and prognosis does not increase , the increased incidence of immediate thrombolysis in myocardial infarction patients in the three grade .

Objective To investigate the prevalence of BPPV in patients with Meniere’s Disease(MD),and to investigate the diagnostic and predictive values of VEMP in patients with MD and BPPV.Methods A total of 1 1 6 patients previously diagnosed MD were followed up through telephone about their BPPV-like attacks.We recorded the detailed history of BPPV-like attacks,and provided them with complete Dix-Hallpike and roll tests if patients were on their BPPV-like attacks.Results In all,4 patients'histories supported BPPV,and 4 patients were found with BPPV.The prevalence of BPPV in patients with MD was 3 .4%(4/1 1 6 ).Meniere's symptoms preceded the on-set of BPPV in 8 patients.In 4 confirmed BPPV patients with Meniere's disease,BPPV was limited to the same ear as the MD in 2 cases,and 1 had contralateral BPPV,and 1 was uncertain.Six histories supported or confirmed BP-PVpatients with high abnormal oVEMP rates (5/6).Four in this 5 (80%)had abnormal oVEMP of the same MD ear.The single repositioning procedures can improve vertigo and eliminated positional nystagmus in cases of BPPV associated with MD.Conclusion In the present study,the prevalence of BPPV in patients with MD was 3 .45%.De-tailed medical histories combined with Dix-Hallpike and roll tests and VEMP tests can identify BPPV in patients with MD.

Objective To understand the eco-hydraulics characteristics of Biomphalaria straminea,the intermediate host of Schistosoma mansoni. Methods The drainage method and settlement tube method were applied to measure B. straminea's den-sity and hydrostatic settling velocity respectively. Results The density of B. straminea was 1.04-1.16 g/cm3,and the average value was 1.08 g/cm3. The hydrostatic settling velocity was 2.32-12.92 cm/s. Conclusions The eco-hydraulics characteristics of B. straminea is different from Oncomelania hupensis,and more attention should be paid to the hydraulic measures for the con-trol of B. straminea.

OBJECTIVE: To analyze the abnormal conditions of the affected ear and the contralateral ear of patients with unilateral Meniere's disease and the prevalence of bilateral abnormalities among these unilateral Meniere disease population, providing reference for the clinical treatment strategies for Meniére disease. METHOD: A retrospective analysis of 106 Meni6re disease cases was performed, the abnormal incidence of the affected ears, the contralateral ears and the bilateral abnormalities were calculated, and the disease characteristics were analyzed. RESULT: The bilateral ears abnormal incidence of unilateral Meniére disease was 35. 85% (38/106); the cochlear symptoms of the contralateral ears often occurred 2. 25 years later of the symptoms of Meni6re disease; contralateral cochlear symptoms included at least two symptoms of tinnitus, deafness and ear fullness; 39. 47%(15/38) patients with bilateral abnormalities would appear binaural hearing impairment. CONCLUSION This study showed that about one-third of unilateral Meniére diseases have binaural symptoms, among which about one-third would occur bilateral hearing loss. Therefore, it is necessary to consider the course of disease and the symptoms of the contralateral ear before taking damage or destructive method for treating Meniére's disease clinically.

Objective To explore the potential risk factors of schistosomiasis transmission so as to provide evidence for setting up the surveillance scheme of schistosomiasis prevention and control. Methods The schistosome infection of local inhabitants, mobile population and stock from endemic areas were investigated from 2002 to 2007 by using IHA or ELISA technique. The historical endemic reports of Chongqing City and the schistosomiasis cases, and the plants imported from schistosomiasis endemic areas and Oncomelania snails were investigated. The behavior of local inhabitants was also investigated. Results The investigated people included 5 112 local inhabitants, 1 455 mobile people from schistosomiasis endemic areas and 1 744 residents returned from the endemic areas. The sero-positive rates of them were 0.57%, 1.44% and 0.86%, respectively. Eighteen cases of imported schistosomiasis were found. There were many plants and stock imported from the schistosomiasis endemic areas. No imported snail was found. The farming of local inhabitants depended on the cattle chiefly. The rate of the harmless lavatories was 14.88%. The local residents had the habit of water contact. Conclusion There are potential risk factors for schistosomiasis transmission in the Three Gorges Reservoir areas. The local residents have potential risk behavior of getting infection of Schistosoma japonicum. The surveillance should be emphasized on the mobile population, imported plants and stock from endemic areas.

Objective To compare the advantages and disadvantages of SNPscan and Sanger sequence which are both used to detect the common deafness gene mutations in non-syndromic hearing loss (NSHL) in Gansu Province.Methods Peripheral blood samples were obtained from Dongxiang, Yugu and Baoan people with moderately severe to profound sensorineural hearing loss in Gansu province to extract genomic DNA.SNPscan was used to detect the 115 mutations in the common pathogenic GJB2 gene, SLC26A4 gene and mtDNA gene.Results We used the SNPscan to screen the mutation of GJB2 gene,mtDNA A1555G and mtDNA C1494T, SLC26A4 gene of sensorinural deafness patients from Gansu Province.The mutation rate of these three genes was 23.18% (35/151), and the mutation rate of Dongxiang, Yugu, Baoan was 21.31% (26/122), 54.54% (6/11), 16.67% (3/18), respectively.Compared with the Sanger sequence, the results were statistically insignificant(P>0.05).The detection rates in the three genes of SNPscan were 11.26% (17/151), 1.32% (2/151) and 0.66% (1/151),respectively , and the detection rates of Sanger sequence were 9.93% (15/151), 1.32% (2/151) and 0.66% (1/151) ,respectively.The results of the two methods were compared.The results were statistically insignificant (P>0.05).Time, cost and flux, SNPscan method is superior to Sanger sequencing.Conclusion Compared with the Sanger sequence, SNPscan is more lighter in workload, less time-consuming, higher-throughput, lower cost, and can get more meaningful mutations and reduce the false negative rates.

Objective To investigate the association between PARK16 gene polymorphism and Parkinson's disease(PD)susceptibility in Chinese Han population.and to analyze its single-nucleotide polymorphism(SNP)genotypes,frequencies and odds ratios(OR)of different genotypes.Methods The association between two SNP loci in PARK16 gene(Rs947211,Rs823128)and PD susceptibility was investigated by TaqMan quantitative polymerase chain reaction(PCR)in 226 PD patients and 362 healthy controls.Allele and genotype frequencies were calculated by the Chi-square test,and the clinical data were also analyzed.Results Three genotypes of Rs947211(GG,AG and AA)account for 34.1%(77/226),46.0%(104/226),19.9%(45/226)in the PD group,and 23.8%(86/362),53.0%(192/362),23.2%(84/362)in the control group,respectively.There was significant difference between two groups (P<0.05).Setting the GG genotype as the reference,OR values of AG and AA genotype were 0.57(95%CI0.38-0.85,P=0.006)and 0.55(95%CI 0.34-0.85,P=0.015),while the OR value for exposure to the A allele(AA+AG)was 0.56(95%CI0.38-0.82,P=0.003).Genotypes of Iate-onset PD were also significantly different from the controls(OR valne of AG=0.46,95%CI 0.27-0.78,P=0.004:OR value of AA=0.35.95%CI 0.18-0.68,P=0.002).And there was no diffefence in clinical features among the 3 genotypes. The frequency of Rs823128, another locus, in PD group was not significantly different from the control group( AA genotype as the reference, OR value of AG was 1. 12, 95% CI 0. 75-1.68, P = 0.568; OR value of GG was 0.99, 95% CI 0.35-2.76, P = 0.994). Conclusion Polymorphism of PARK 16 locus Rs947211 is associated with PD patients in Chinese Han population.

The purpose of this study was to fabricate decelluarized valve scaffold modified with polyethylene glycol nanoparticles loaded with transforming growth factor-β1 (TGF-β1), by which to improve the extracellular matrix microenvironment for heart valve tissue engineering in vitro. Polyethylene glycol nanoparticles were obtained by an emulsion-crosslinking method, and their morphology was observed under a scanning electron microscope. Decelluarized valve scaffolds, prepared by using trypsinase and TritonX-100, were modified with nanoparticles by carbodiimide, and then TGF-β1 was loaded into them by adsorption. The TGF-β1 delivery of the fabricated scaffold was measured by asing enzyme-linked immunosorbent assay. Whether unseeded or reseeded with myofibroblast from rats, the morphologic, biochemical and biomechanical characteristics of hybrid scaffolds were tested and compared with decelluarized scaffolds under the same conditions. The enzyme-linked immunosorbent assay revealed a typical delivery of nanoparticles. The morphologic observations and biological data analysis indicated that fabricated scaffolds possessed advantageous biocompatibility and biomechanical property beyond decelluarized scaffolds. Altogether this study proved that it was feasible to fabricate the hybrid scaffold and effective to improve extracellular matrix microenvironment, which is beneficial for an application in heart valve tissue engineering.

Objective To evaluate the expressions and its clinical significance of Foxj2 in non-small cell lung cancer (NSCLC) patients.Methods Fifty cancer tissues from patients who underwentsurgery were collected.Western blot and immunohisto-chemical methods were used to detect the expressions of Foxj2.Results Results of western blot showed that Foxj2 expres-sion in lung cancer tissue was significantly lower than adjacent tissues.The difference between the two groups was statisti-cally significant(P<0.05).Immunohistoehemical results showed that the number of Foxj2-positive cells in adjacent tissues was significantly higher than that in cancer tissues,and the expression of Foxj2 in non-lymphatic node metastasis group was higher than that in lymphatic node metastasis.The difference between the two groups was statistically significant (P<0.01).Conclusion The expressions and location of Foxj2 was related to the lymphatic node metastasis of lung cancer.This phenomenon indicates that Foxj2 may play an important role in the development of lung cancer.

OBJECTIVE: To investigate the result of vestibular evoked myogenic potentials (VEMP) of primary benign paroxysmal positional vertigo(BPPV)and to identify the characteristics in VEMP examination of the primary BPPV and to observe the relevance of patients with primary BPPV and abnormal VEMP with hearing loss. METHOD: Patients with primary BPPV were tested with pure tone audiometry, videonystagmograph and VEMPs test. We analyzed the difference in the two groups with normal hearing and hearing loss, discussed the etiology and pathogenesis. RESULT: Primary BPPV comprised 23.0% with hearing lost, 77.0% hearing normal. The results of oVEMP were abnormal in 79. 7% (59/74) of the cases; and the results of cVEMP were abnormal in 66. 2% (49/74) of the cases; oVEMP and cVEMP differences to the diagnosis of primary BPPV (P<0. 05); oVEMP and cVEMP differences to the diagnosis primary BPPV with hearing lost (P<0. 05). CONCLUSION oVEMP detection positive rate of primary BPPV is higher than cVEMP,which may be due to otolithic particles falling from the utricle; positive rate of cVEMP in primary BPPV with hearing loss is higher than that of oVEMP, which may related to the cochlear and sacculus occured in the same embryonic tissue structure.
