Objective To investigate the role of intestinal fatty acid binding protein (IFABP) and blood procalcitonin (PCT) in diagnosis of traumatic Intestinal rupture in early stage.Methods The clinical data of 58 patients with abdominal injuries admitted from May 2012 to April 2016 were retrospectively analyzed.All 58 patients were divided into intestinal rupture group (n =21) and nonintestinal rupture group (n =37).The concentrations of IFABP and PCT were detected,analyzed and compared between two groups at different intervals.Results The IFABP and PCT in intestinal rupture group were significantly higher than those in non-intestinal rupture group.The IFABP and PCT in intestinal rupture group significantly decreased after operations.There were significantly differences in IFABP and PCT between two groups at admission,4 hours after admission,preoperative period,and 24 hours after operation.However,these differences disappeared at 72 hours after operation.At the same time,the accuracy rate 92.4％,sensitivity 96.3％,specificity 72.8％ found in combination of these two biomarkers were significantly higher than those of IFABP and PCT measured separately.Conclusions The combination of IFABP and PCT detection can be used as an indicator for the diagnosis of traumatic intestinal rupture in the early stage.

Objective To investigate the role of expressions of pituitary tumor transforming gene(PTTG) and p27 in glioma,and explore the relationship between the expressions of them and cell cycle regulation.Methods Specimens of 40 patient with gliomas were divided into gradeⅠ:8 cases,gradeⅡ:10 cases,gradeⅢ:13 cases, gradeⅣ:9 cases,PTTGmRNA and p27mRNA were detected by reverse transcription polymerase chain reaction (RT-PCR),and their expressions of PTTG,P27,CDK4 protein were detected by immunostaining assay using strep- tavidin-peroxidase(SP) method.Results The expressions of PTTGmRNA in gradeⅠ～Ⅳwere (0.907?0.065),(1.109?0.083),(1.312?0.089),(1.499?0.215) respectively,there was significant difference among the groups(P

Objective To profile the omp1 genotypes of Chlamydia trachomatis (Ct) in patients with nongonococcal urethritis (cervicitis) in Guangzhou region. Methods Swab samples were obtained from the urethra of males and cervix of females in clinical settings of venereology and gynecology as well as at outreach sites for the prevention and control of sexually transmitted diseases (STDs). DNA was extracted from the swabs and nested PCR was performed to amplify the variable domain (VD) 1 - 3 of omp1 gene of Ct followed by gene sequencing. The genotypes of Ct were determined based on the amino acid mutation in VD 1 - 2 of omp1 gene. Results Totally, 1208 swabs were collected. Of them, 132 were Ct positive, and 130 positive samples underwent genotyping. Ten ompl genotypes were determined in total, including serotype E (38, 29.23%), D (25, 19.23%), J(24, 18.46%), F(21, 16.15%), G(7, 5.38%), H(5, 3.85%), K(5, 3.85%), B(2, 1.54%), Ja (2, 1.54%), I (1, 0.77%). E, D, J and F were the dominant type of Ct in this region, and amounted to 83% of all the Ct isolates. Mutations were observed within VD 1 and 2 of omp1 gene in serotype D, B and K.Serotypes were undetermined for Ct in 2 patients with mixed infection. Conclusions In Guangzhou region, E,D, F and J are the predominant genotypes of Ct, and amount to 83% of all the Ct isolates. Ct serotype B is also observed in the urethra of males and cervix of females in this region.

Objective To evaluate the diagnostic value of MSCT in Solitary Pulmonary Nodules (SPN) with different pathologic types .Methods Four-five SPN with pathological findings including 16 benign cases and 29 malignant cases were retrospectively an-alyzed ,and performed with MSCT scanning .Observation of the distribution ,morphology and internal characteristics of SPN by post-processing technique were done ,and the results were compared with pathological findings .Results Among 45 SPN ,the benign nodules included 6 cases of inflammatory pseudotumor ,4 cases of tuberculoma ,3 cases of hamartoma ,2 cases of cryptococcus and 1 case of hemangioendothelioma ,and the malignant nodules included 21 cases of adenocarcinoma ,3 cases of squamous carcinoma ,2 ca-ses of small cell carcinoma and 3 cases of alveolar cell carcinoma .Average diameter of benign nodules was 2 .1 cm ,and 2 .6 cm for the malignant nodules .All SPN ,including 5 cases in the inner zone ,12 in the medial zone and 28 in the lateral zone ,the percentages with malignant signs at the corresponding parts were 40% (2/5) ,50% (6/12) ,75% (21/28) ,there was significant difference be-tween distributions(P<0 .05) .The distributions of malignant nodules in the upper and lower lung lobe had no significant difference (P>0 .05);the incidences of leaf sign ,burr sign ,pleural indentation sign ,cavitas and bronchial air sign ,blood vessels cluster sign of malignant nodules were higher than that of the benign nodules(P<0 .05) ,and the inflammatory pseudotumor and adenocarcinoma owned similar characteristics ;the incidence of calcification in tuberculoma and hamartoma was high ,while cavitas in tuberculosis and lung cancer were high .Conclusion MSCT can sufficiently display the distribution ,morphology and internal characteristics of SPN , and can help make qualitative diagnosis of benign and malignant SPN ,providing great practical value in clinical treatment .

Objective To investigate the utilization of damage control surgery (DCS) in treatment of the severe abdominal traumas.Methods The clinical data of 56 patients with severe abdominal traumas treated by DCS (Emergency operation,fluid resuscitation and definitive operation were used gradually.)from January 2011 to January 2013 in Department of General Surgery,Taizhou People's Hospital were retrospectively analyzed.Results Of the 56 patients,52 were cured and discharged from hospital,the clinical curative rate was 92.9％; 4 patients dead.Conclusions Abdominal traumas under going operations by applying the damage control surgery significantly increased the clinical curative rate.

Objective Coralline hydroxyapatite (CHA),in comparison with Bio-Oss bone meal,is a material with extensive resources but no immunogenicity or risk of disease-transmission. The aim of this article was to study the clinical application of CHA in ridge preservation in the maxillary anterior zone. Methods Twenty-six patients underwent extraction of maxillary anterior teeth (n=26) for chronic periodontitis or periapical periodontitis. The patients were randomly assigned into a CHA and a control group of equal number to receive ridge preservation with CHA and Bio-Oss bone meal respectively. Cone beam computed tomography (CBCT) was performed immediately and at 4 months after ridge preservation to compare the vertical and horizontal alterations of the alveolar ridge be-tween the two groups of patients. Results After ridge preservation,both the CHA and control groups showed a reduction in the width ([1.1±0.7] vs [1.3±1.9] mm) and height of the alveolar ridge ([1.3±1.6] vs [1.2±1.4] mm),but with no statistically significant differences between the two groups (P<0.05). Conclusion For ridge preservation in the maxillary anterior zone,CHA has a similar effect to that of Bio-Oss bone meal and therefore is an ideal material for bone graft.

OBJECTIVETo construct the eukaryotic expression plasmid of mouse histone lysine methyltransferase Setd7 and detect its effect on neuron development.

METHODSThe clone of mouse Setd7 was obtained and inserted into the eukaryotic expression vector pCMV-3tag-6-Flag. The plasmid was transfected into HEK 293T and identified by Western blot. Real-time PCR was used to detect the effect of Setd7 on the neuron differentiation marker gene Ngn 1 mRNA expression. Dual luciferase reporter system was used to detect the effect of Setd7 on Ngn 1 mRNA expression. Real-time PCR was used to detect the effect of Setd 7 siRNA plasmid on Ngn 1 mRNA expression.

RESULTSAn eukaryotic expression plasmid of Setd 7 was successfully constructed. Setd7 induced Ngn 1 mRNA expression and increased Ngn 1 promoter activity. Also, the knockdown of Setd 7 inhibited Ngn 1 mRNA expression.

CONCLUSIONHistone lysine methyltransferase Setd7 can enhance neuron differentiation marker gene Ngn 1 transcription.
