3 month),fluid sign was observed in 2(3 vertebrae,3/26,11.5%). Conclusion Fluid sign is characteristic in acute,subacute and early chronic trauma vertebral compression fracture for bone marrow edema,while it is rare in metastatic tumor vertebral compression fracture.It may paly a role in the differentiation of benign and malignant vertebral compression fracture.

Objective To investigate the effects of intravenous immunoglobulin(IVIG) on apoptosis and necrosis of myocytes in mice with viral myocarditis.Methods Three hundreds and twenty Balb/c mice were randomly divided into 8 groups.Different courses of IVIG were given in varying time after virus inoculation,Chinese medicine Huangqi given in control group.The virus titer in myocardium、percentage of apoptosis and necrosis of myocytes were detected, myocardial histopathologic scores were counted.Results In every IVIG treatment group,the above 3 items were all significantly lower than that in virus control group and Huangqi group,as IVIG early long course group had the best effect.Conclusion IVIG may reduce the percentage of apoptosis and necrosis of myocytes and virus titer in myocardium in mice with viral myocarditis,the effects are better than that of Huangqi.

Objective To study the correlations of VDR FokⅠgene polymorphism with type 2 diabetes in postmenopausal women of Han nationality in south Sichuan. Methods 160 patients with type 2 diabetes (T2DM) and 190 healthy cases were enrolled in the study. The VDR FokⅠgene polymorphisms were detected using RFLP-PCR and DNA sequencing. Results The FF, Ff and ff genotype frequencies were 32.5%, 47.5%and 20% in the T2DM group and 15.8%, 53.7%, 30.5% in the control group, respectively (P < 0.05). The allele frequencies were 56.3%, 43.8% in the T2DM group and 42.6%, 57.4% in the control group, respectively (P < 0.05). The risk of T2DM in the FF genotype people was 2.568 times higher than Ff/ff genotype (adjusted OR = 2.568, 95%CI = 1.246 ~ 5.292, P < 0.05). The levels of 2 h PG and HbA1C in the FF genotype people were significantly higher than those of the Ff/ff genotype people (P<0.05). Conclusions There was an association between the VDR FokⅠgene polymorphism and type 2 diabetes incidence in the postmenopausal women in south Sichuan area.

Objective:To establish a double antibody sandwich ELISA assay for detection of human IL-37 in serum.Methods: Mouse anti-human IL-37 monoclonal antibody was used as capturing antibody,rabbit anti-human IL-37 polyclonal antibodies served as detection antibody,HRP labeled goat anti-rabbit IgG employed as second antibody and recombinant human IL-37 protein used as reference standard for the establishment of a doubleantibody sandwich ELISA.The working conditions were optimized,such as sensitivity,linear range,reproducibility and evaluated the serum IL-37 in patients with Dengue fever.Results: The sensitivity of the established ELISA method was 1.465 μg/L approximately.Likewise,the linearity range of this method was about (1.465-46.875) μg/L.Further,the co efficient of variation (CV) of inter-batch and intra-batch in this study were 6.6％ and 11.7％,respectively.Notably,this method could be used in the detection of IL-37 in serum of the patients with Dengue fever,showing that the level of IL-37 in Dengue fever patients was much higher than that in healthy controls.Conclusion: The double antibody sandwich ELISA assay for the detection of human IL-37 was successfully established,which can be apply to detect of human IL-37 in clinical samples.

Objective To investigate the correlation between the indications,findings,interventions of fibrobronchoscopy(FB) in neonates and their correlative diseases with neonatal FB results and clinical data.Methods Retrospective case series of 243 consecutive patients of 28 days old or younger were investigated underwent FB for the first time from January 2010 to December 2014,at a tertiary care hospital.The common indications for FB and detection rate of respiratory tract diseases were collected.If the findings of FB had significant associations with premature birth and other diseases were analyzed.Associations between interventions and basic illnesses were also analyzed.Results Of the 243 patients undergoing 275 procedures of FB,201 cases were boys(73.1％).The age of FB was (13.34 ± 9.76) days and the weight was (3.08 ± 0.68) kg.Forty-five cases were premature infants (16.4％).A total of 254 procedures were found to have congenital diseases (92.4％),and 177 cases of them had congenital heart diseases (CHD) (64.4％).Common indications for FB were dyspnea(140 cases,50.9％),tachypnea(82 cases,29.8％),and stridor(71 cases,25.8％).A total of 188 upper airway lesions were found and the most common findings were laryngomalacia(56 cases,20.4％) and vocal cord paralysis(bilateral/unilateral,50 cases,18.2％).A total of 315 lower airway lesions were found and the most common findings were airway mucosal inflammation (98 cases,35.6％),trachea and main bronchial stenosis (73 cases,26.5 ％).A total of 21 cases (7.6％) underwent supraglottoplasty during or after FB,while 17 cases (6.2％) underwent tracheal dilation and 10 cases (3.6％) underwent tracheotomy.Compared with non-CHD neonates,neonates with CHD were statistically significantly less likely to have congenital lesions statistically,such as laryngomalacia(15.8％ vs.28.6％,P =0.012),bilateral vocal cord lesions(6.2％ vs.21.4％,P =0.000) and congenital laryngeal dysplasia(0 vs.7.1％,P =0.001).The tracheotomy(0 vs.10.2％,P =0.000) and supraglottoplasty(2.3％ vs.17.3％,P =0.000) were more rare.Nevertheless,they were more likely to have secondary lesions such as the left main bronchial stenosis caused by extrinsic compression (23.7％ vs.1.0％,P =0.000),abnormal bronchial anatomy(9.6％ vs.2.0％,P =0.018),left vocal cord paralysis(9.0％ vs.1.0％,P =0.008) and airway mucosal inflammation(41.8％ vs.24.5％,P =0.004).The tracheostenosis and main broncial stenosis (37.3％ vs.7.1％,P =0.000) with long-term intubation(78.5％ vs.58.2％,P =0.000) were more common.There was no significant difference between term neonates and premature infants in the detection rate of respiratory tract diseases (P ＞ 0.05),tracheotomy (0 vs.4.3 ％,P =0.322),supraglottoplasty (13.3 ％ vs.6.5 ％,P =0.205) or long-term i ntubation (80.0％ vs.69.6％,P =0.157).Complications caused by procedure were rare and mild.Conclusions FB can detect whether the neonates with dyspnea,tachypnea and stridor have laryngomalacia,vocal cord paralysis,airway mucous edema,tracheal and main bronchial stenosis and other signs,and FB may play an important role in diagnosis,treatment and prognosis evaluation of neonatal respiratory diseases.

Using the new negative pressure biopsy technology, the automatic negative pressure gun and the specific puncture needle for the biopsy have been developed. Renal biopsies were conducted in 1136 cases, with the success rate being 99.9%, and 29 cases gross hematuria while the hepatic biopsies were conducted in 16 cases, mass biopsies in 3 cases with the success rates being 100% respectively. The biopsy gun has the advantages of easy manipulation, higher success rate and lower incidence of complications.

OBJECTIVETo identify patterns of hand, foot and mouth disease (HFMD) incidence in China during declining incidence periods of 2008, 2009, and 2010.

METHODSReported HFMD cases over a period of 25 months were extracted from the National Disease Reporting System (NDRS) and analyzed. An interrupted time series (ITS) technique was used to detect changes in HFMD incidence rates in terms of level and slope between declining incidence periods of the three years.

RESULTSOver 3.58 million HFMD cases younger than 5 years were reported to the NDRS between May 1, 2008, and May 31, 2011. Males comprised 63.4% of the cases. ITS analyses demonstrated a significant increase in incidence rate level (P<0.0001) when comparing the current period with the previous period. There were significant changes in declining slopes when comparing 2010 to 2009, and 2010 to 2008 (all P<0.005), but not 2009 to 2008.

CONCLUSIONIncremental changes in incidence rate level during the declining incidence periods of 2009 and 2010 can potentially be attributed to a few factors. The more steeply declining slope in 2010 compared with previous years could be ascribed to the implementation of more effective interventions and preventive strategies in 2010. Further investigation is required to examine this possibility.
