ABSTRACT
Objective To investigate the tumor/ non-tumor (T/ NT) ratio during 99 Tcm-hydrazinon-icotinamide(HYNIC)-( poly-( ethylene glycol), PEG) 4-Glu( cyclo ( Arg-Gly-Asp-D-Phe-Lys ( PEG4 ))) 2 ( 99 Tcm-3PRGD2 ) SPECT/ CT imaging and clinical pathological features of breast cancer. Methods Forty-five female patients (age range: 39-76 (53.0±9.5) years) with suspected breast malignant nodules or mas-ses from October 2016 to June 2017 were prospectively enrolled. Patients underwent 99 Tcm-3PRGD2 SPECT/CT imaging before breast puncture and surgery. All subjects had pathological results, and estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2(HER-2), Ki-67 and mi-crovessel density ( MVD) were obtained by immunohistochemistry and fluorescence in situ hybridization(FISH). Two-sample t test and Kruskal-Wallis H test were used to analyze the data. Results Invasive duc-tal carcinoma was pathologically confirmed in 35 of 45 patients. There were 7 patients in stage Ⅰ, 11 pa-tients in stage ⅡA and 17 patients in stage ⅡB. The Luminal A subtype, Luminal B subtype, ERBB2+subtype, Basal-like subtype were found in 6, 9, 9 and 11 patients, respectively. The T/ NT ratio was signifi-cantly higher in the stageⅡB patients than that in stageⅠ+ⅡA patients (4.54±1.46 vs 3.32±1.72, t= -2.24, P<0.05). Patients with ERBB2+ subtype had higher T/ NT ratio compared to patients with Basal-like sub-type: 5.80(3.90, 6.70) vs 2.80(2.20,3.50), H= 11.06, χ2 = 15.31, both P<0.05. Besides, the T/ NT ra-tios in the HER-2 positive group and lymphatic metastasis group were significantly higher than those in the HER-2 negative group and group without lymph node metastasis (t values: -3.99, -2.51, both P<0.05). MVD of HER-2 positive group was higher than that of HER-2 negative group (t= 7.13, P<0.01). Conclu-sion The T/ NT ratio during 99 Tcm-3PRGD2 SPECT/ CT imaging has relations with TNM staging, lymph node infiltration and HER-2 in breast cancer.
ABSTRACT
Objective To explore the influence of group B Streptococcus screening during pregnancy and the incidence of the ear‐ly‐onset GBS disease for newborns .Methods Totally 47 cases of pregnant women with premature rupture of membranes (PROM ) , which were GBS positive and accepted antibiotic treatment ,who were chosen as the experimental group .While 73 cases of pregnant women with premature rupture of membranes (PROM) ,which were not accept GBS screening and antibiotic treatment ,were chosen as control group .The neonatal clinical manifestations were observed .The swab specimens were collected from throat and detected of GBS by using PCR method .Results The experimental group showed no occurrence of neonatal group B streptococcal infection , dyspnea ,cyanosis and fever .Totally 7 cases of the control group had group B Streptococcus infection .Totally 2 cases had dyspnea and 2 cases had cyanosis .Totally 4 cases had fever .The neonatal research indicators of these two groups were statistically signifi‐cant differences (P<0 .05) .Conclusion The group B Streptococcus screening during pregnancy would effectively reduce the inci‐dence of neonatal infection of group B Streptococcus .
ABSTRACT
Objective To evaluate the feasibility and efficacy of endoscopic push?radial dissection (EPRD)for benign esophageal stricture(BES). Methods Clinical data of 24 patients diagnosed as having BES who received EPRD were analyzed. The procedure and efficacy were evaluated. Results All 24 patients underwent EPRD successfully with mean operation time being 32 min(15?45 min).The mean esophageal stric?ture incision length was 3?? 2 cm (1?? 0?8?? 0 cm).No severe complications related to EPRD occurred, or trans?ferred for surgery. Patients were followed up for 1?5 months (mean 2?? 8 months). Dysphagia was relieved signif?icantly during the follow?up in 23 patients where endoscopy could go through smoothly. But dysphagia re?oc?curred in one patient 2 weeks after the operation, who underwent a second EPRD and stent implantation, then dysphagia was relieved. Conclusion EPRD is safe, feasible and effective for benign esophageal stricture.
ABSTRACT
Summary: In order to objectively evaluate the efficacy of intravenous gammaglobulin (IVIG) in the prevention and treatment of coronary artery lesion (CAL) in Kawasaki disease (KD) and the related factors influencing the IVIG efficacy, 314 children with KD were reviewed retrospectively and comparatively and were divided into IVIG plus aspirin group and ASA group. The occurrence and restoration of CAL in these two groups as well as many laboratory and clinical indexes including average hospital stay (days), total fever duration, defervescence time, platelet count, erythrocyte sedimentation rate, C reactive protein etc. were observed. The incidence of CAL was 39.5 % in the children with KD. In the IVIG+ASA group, the incidence of CAL was 34.3 % and 56.0 % in ASA group respectively (P<0.001). The incidence of CAL was reduced in the group in which 2.0 g/kg or 1.0 g/kg IVIG was administered as compared with the group in which IVIG was administered at a dose ≤0.6 g/kg or ≥3.0 g/kg (P<0.05). CAL occurred less frequently when IVIG was administered at 3-10 days of the course than that when IVIG was administered ≤3 days or >10 days (P<0.05). About 13.4 % of the CAL treated with IVIG was not recovered at the 12 th month of the course, mostly in the groups in which only ASA was administered and IVIG treatment was started 10 days later. The hospital stay (days), defervescence time, total fever duration, platelet count, erythrocyte sedimentation rate and C reactive protein were significantly reduced in IVIG+ASA group as compared with those in the ASA group (P<0.05). IVIG treatment can remarkably shorten the course of patients with KD and decrease the incidence of CAL, but the efficacy of IVIG in the prevention and treatment of KD disease is not as expected by people, therefore, reevaluation of the practical efficacy of IVIG is required.
ABSTRACT
Objective To explore the value of maximun P wave duration (P max ) and P wave dispersion (P d),that is,the difference between the maximum and minimun P wave duration in patients with idiopathic paroxysmal atrial fibrillation.Methods P max and P d were measured from 12 lead surface electrocardiogram among 20 patients with a history of idiopathic paroxysmal atrial fibrillation and 20 age matched healthy control subjects.Results P max and P d were found to be significantly higher in patients with a history of idiopathic paroxysmal atrial fibrillation than in the control subjects(P
ABSTRACT
Object To explore the bacteriostatic and anti inflammation activities of ultrasonically nebulized Houttuynai cordata Thunb in patients after pneumonectomy Methods The patients were randomized into 2 groups Patients of the experimental group, inhaled ultrasonically nebulized H cordata, while patients in the control group inhaled ultrasonically nebulized vapors without the addition of H cordata Results Total leucocyte counts on the third and fourth day in the experimental group were significantly lower than that in the control group Neutrophil ratio in experimental group was also lower in all the 5 days of treatment although nonsignificantly Meanwhile, occurrence of Gram negative bacilli colonization in experimental group occurred less than that in the control group But incidence of fungi colonization appeared higher Conclusion Inhalation of ultrasonically nebulized H cordata can ease the inflammation and inhibit the colonization of Gram negative bacilli in respiratory tract
