The purpose of this study was to assess the diagnostic value of main frequency of transient evoked otoacoustic emissions for Meniere's disease. The click- evoked transient otoacoustic emissions(TEOAE) in normal subjects and in patients with Meniere' s disease were examined using ILO 88 otodynamic analyzer system to observe the main frequency distrbution. The main frequeencies ranged from 1.2 to 1.6 kHz in normal ears, and from 0.8 to 1. 1 kHz in Meniere' s ears. The main frequency range of normal ears was obviously higher than that in Meniere's ears. After application of glycerol, the main frequencies in some Meniere's ears were shifted from relative low frequency range to relative high frequency range. TEOAE appeared in some Meniere's ears in which TEOAEs could not be evoked before application of glycerol. The results suggest that the TEOAE can be used in the diagnosis of Meniere's disease.

Objective To investigate the induced-factors levels of venous thrombosis associated with the placement of peripherally inserted central catheters (PICC) in patients with malignant tumor,and establish intervention model accordingly. Methods 40 patients complicated with venous thrombosis after PICC were set as the thrombosis group, 40 patients without venous thrombosis were selected as the no-thrombosis group, 30 healthy cases were selected as the control group. All cases' serum samples were ob-tained to measure the levels of molecular biomarkers of the coagulation system, platelet parameters and molecular biomarkers of the fibrinolysis system. The results of the three groups were assessed. Results Patients in the thrombosis group were reported significantly higher levels of vWF, GMP140,TAT than those in both two other groups, but lower levels of ATⅢ. Higher levels of MPV and PCT were found in the throm-bosis group than those in both two other groups.Tthe data also showed higher PLG and PAI levels and lower levels of PLM in the thrombosis group. Conclusions From this study it shows that patients with malig-nant tumors during the placement of PICC have evident hypercoagnlahility, high- activated platelet and se-vere pre- thrombosis state caused by PICC. In treatment of malignant tumor patients with PICC, the level of coag-ulation system molecular markers, platelet parameters,fibrinolysis molecular markers shoud be used as a clinical routine and as the index of early intervention and evaluation of the PICC.

Objective To explore the clinical value of fetal syetem ultrasound union real-time three-dimensional ultrasound to diagnose the abnormalities of fetal palms and feet in medium-term pregnancy.Methods The results of fetal syetem ultrasound u-nion real-time three-dimensional ultrasound in 23 675 cases during dmedium-term pregnancy in our department from January 2009 to November 2013 were retrospectively analyzed,including 47 350 palms and feet.Results If using the fetal syetem ultrasound u-nion real-time three-dimensional ultrasound to examine fetal palms and feet more than three times,the display rate of palms and feet was 100.0%,while the first-time display rate of finger and toes was 81.2%,second-time display rate was 97.2% and the third-time and more display rate more thatn 99.8%.136 cases hand-foot deformity were diagnosed,including 37 cases of hand gesture abnor-malities,6 cases of finger abnormalities,93 cases of food abnormalities,and the main abnormality was strephexopodia.Of all the 136 cases,there were 2 cases also with Trisomy 18,4 cases with Trisomy 21.Conclusion Malformations of fetal palms and feet can be detected by fetal system ultrasound combined with real-time three-dimensional ultrasonography during the second trimester,which is important indicators of prenatal screening for chromosomal abnormalities.

Objective To investigate the related factors of phlebitis caused by PICC and support effective preventive nursing measures. Methods 163 patients diagnosed as malignant tumor who first used peripherally inserted central catheters (PICC) were recruited. Patients were observed for 3 months. According to the diagnostic criterion of infection, 34 patients with phlebitis were divided into the phlebitis group and others were divided into the control group. All patients were investigated for general information survey :sex, age, tumor type, allergic history,location of inserted vein, one-time success rate,activity after catheter, elbow bending,phlebitis occurred time, grade and type. Laboratory markers:WBC,neutrophils,immune parameters, fasting plasma glucose. Trait anxiety inventory (T-AI)was used for assessment of emotional state. Case-control study between groups was carried out. Results The results of univariate analysis showed that location of inserted vein,times of inserting vein,activity of inserted limb,elbow bending,blood sugar level and emotion were associated with phlebitis. Sex, age, tumor type, allergic history, immune function,WBC,neutrophils were not involved with phlebitis. The results of multivariate logistic regression analysis showed that PICC through basilica vein was the protective factor. Multiple insertions, more activity of inserted limb,durative anxious emotion were the risk factors of phlebitis. Conclusions Different location of vein,times of inserting vein,activity of inserted limb,elbow bending,high blood glucose level and persistent anxious emotion are the risk factors of phlebitis. Taking effective preventive measures before,during, and after PICC can reduce the incidence of phlebitis.

OBJECTIVE: To systematically analyze the local recurrence of CO₂ laser surgery for early glottic cancer and without anterior commissure involvement. METHOD: By searching CBM, CNKI, wanfang, weipu, PubMed, Embase, OVID, and Springer database, the retrospective clinical studies were included according to inclusion and exclusion criteria. Meta analysis of extracted data was carried out by RevMan 5.0 software.

Objective To investigate the relationship between putative rs5744168 of Toll-like receptors 5 (TLR5)and ANCA associated small vasculitis (AAV) in Guangxi Han nationality. Methods Polymorphism was analyzed by polymerase chain restricted fragments length polymorphism in 120 cases with AAV and 212 controls. Results (1)There were two genotypes of CC and CT in AAV group and control group. The frequencies distribution of CC and CT in 120 AAV patients were 82.50% and 17.50% respectively and the frequencies of allele C and T 91.25% and 8.75%,respectively. In controls,the genotypefrequencies of CC and CT were 88.68% and 11.3%, and frequencies of allele C and T 94.34% and 5.66%, respectively. No significant difference was found in either genotype distribution or allele frequencies between the patients and the controls ( P > 0 . 05 ) . ( 2 ) Significant reductions in the incidence of BUN, uric acid, quantitative test of 24 h urinary protein and erythrocyte sedimentation rate(ESR) were found in CC genotype (P < 0.05). (3) Binary regression model with a logit link function found total cholesterol was related with AAV. Conclusion The susceptibility of AAV in Guangxi Han population has nothing to do with the polymorphism of rs5744168.In AAV patients, polymorphism of rs5744168 may be associated with ESR, BUN, uric acid and quantitative test of 24 h urinary protein levels.

Objective To investigate the correlations between the displacements of surgical clips,skin markers and the gross tumor volume (GTV) delineated by surgical clip and seroma based on fourdimensional computed tomography (4DCT) during normal breathing.Methods On each of the 10 respiratory phases of 4DCT with 15 patients of breast cancer,the surgical cavity,which was defined as GTV and formed by both surgical clips and seroma,all surgical clips in the cavity,and skin markers on the skin were delineated by the same radiation oncologist.The center displacements of GTV,selected boundary surgical clips and skin markers in the left-right (LR),anterior-posterior (AP),and superior-inferior (SI) directions were recorded and analyzed by Pearson method.Results In the AP direction,there was a positive correlation between the displacements of the GTV and the inner clip (r =0.643,P =O.013).In the SI direction,the displacement of GTV was positively correlated with those of the lower clip and the skin marker at anterior body midline (r =0.857 and 0.643,P =0.002 and 0.013).In the LR and AP directions,there was a positive correlation between the displacements of the outer clip and the ipsilateral skin marker (r =0.757 and 0.697,P =0.001 and 0.025),but they were negatively correlated with each other in the SI direction (r =-0.647,P =0.043).In the AP direction,there was a positive correlation between the displacements of the inner clip and the skin marker at the anterior body midline (r =0.738,P =0.015).Conclusions The correlations between the displacement of GTV delineated by surgical clips and seroma and the displacements of surgical slips and skin markers vary under different conditions,and so does the correlation between the displacements of surgical clips and skin markers.
