China Medical Equipment 2017;14(1):45-47,48
Objective:To research the application value of coronary CT angiography(CTA) detection for epicardial adipose tissue(EAT) and pericardial adipose tissue(PAT) in the diagnosis of coronary stent restenosis.Method:Selected 68 cases coronary atherosclerotic stenosis patients who were treated by coronary stent from June 2012 to June 2013 in hospital. All patients were detected after the operation of CTA within 3 years and they were divided into two groups (coronary stent restenosis positive group included 29 cases, negative group included 39 cases). To analyze the relationship between EAT and PAT through the statistical method and analyze the application value of EAT and PAT in the diagnosis of coronary stent restenosis based on calcification score image measurement of EAT and PAT volume.Results: Correlation analysis results showed there was correlation between EAT volume and PAT volume (r=0.859,P<0.05); through compared CAG and the diagnostic results of coronary artery stent restenosis by EAT and PAT, the sensitivity was 82.87%, specificity was 84.62%, CCTA positive predictive value was 80.00%, negative predictive value was 86.84% and diagnostic accuracy was 83.82% of the stent patency which was evaluated by CAG. The consistency evaluation marker Kappa was 0.554. The analysis of patients with coronary stent restenosis showed that there was significant correlation between Gensini score of coronary stent restenosis and EAT and PAT(P<0.05).Conclusion:There was significant correlation between EAT volume and PAT volume, and they can be used to evaluate the sensitivity and specificity of coronary stent operation restenosis and the results were higher. Besides, its clinical diagnostic value was similar with CAG.

Sepsis has relatively high morbidity and mortality in patients at intensive care unit (ICU). With the study of sepsis having continued to develop in recent years, the defects existing in this research have unceasingly exposed. Because the lack of design process of international standardized clinical randomized controlled trials (RCT) for septic patients, the situation of incomplete data record exists in these clinical studies, that may further affect the interpretation of the research results, therefore it is in urgent need to have an international standardized RCT design process for septic patients.

Objective To evaluate the value of imaging examination and diagnosis of airway foreign body in children. Methods 218 of airway foreign bodies confirmed by bronchoscopy were retrospectively analyzed in terms of clinical and imaging data. Results 218 patients included 140 males and 78 females. Their ages ranged 6 months to 12 years(mean,19.2 months). All patients had conventional radiographs on frontal chest films,neck lateral films and fluoroscopy. 34 cases underwent 64-slice spiral chest CT examination. According to the location of the foreign bodies,29 cases were in throat and subglottic,55 cases in trachea and 134 cases in bronchus(79 cas-es in the right,55 cases in the left). According to the character of the foreign bodies,5 cases were metal,29 cas-es in bone,93 cases in peanuts,59 cases in seeds,22 cases in fruits and vegetables and 10 cases in others respec-tively. Thirty-fourcases showed a direct sign of the foreign body and 177 cases showed the indirect signs. 34 cases on CT examination directly were showed foreign body in the tracheal bronchi. The diagnostic accuracy of CT exami-nation was 100%. Conclusions X-ray photograph and fluoroscopy were the first choice for aspiratory foreign bod-ies in children. CT examination is an important supplementary method when conventional X-ray examination is neg-ative.

Human colostrum and milk collected at different times during the first six months of lactation from 301 subjects were tested for the levels of SIgA, IgM, IgG, C3, C4, lactoferrin and lysozyme by the technique of radial immunodiffusion. These kinds of immunoglobulins in colostrum and milk were detected, however the SIgA was highest among immunoglobulins in colostrum, which acounted for 89.8%.The average level of SigA on the first day of postpartum was 3152.5 mg/dl and exceeded those in the serum by 13-fold. It was suggested that breast-feeding may be crucial for the newborns before their mucosal immune system has been established. The average levels of C3 and C4 on the first day of postpartum were 99.7mg/dl and 65.9mg/dl respectively, reaching the normal serum level. Lactoferrin was as high as 1228.7mg/dl in the colostrum of the first day of lactation. The concentration of lysozyme was 944.2ug/ml on the first day of postpartum, which was about 429 times higher than that of cow milk. Using Holder pasteurization (62.5℃, 30 minutes), the SIgA and lysozyme activity of the milk could be reduced by 29.7% and 8.3% respectively, but a lot of anti-infective factors still remained in milk. So pasteurization may be useful for the sterilization of stored human milk.

Objective To explore effect of rehabilitation training on deglutition disorders of children with cerebral palsy . Methods Twenty-seven children patients from January to June in 2013 were set as control group and thirty-one patients from July 2013 to January 2014 as experiment group. The children in the control group were treated with tube-feeding combined with spoon feeding and bottle-feeding by professional nurse. Children in the experiment group were treated with oral rehabilitation training by professional therapists and nurses apart from the same feeding as in the control group. The two groups were compared in terms of effect of deglutition within 4 weeks, time and rate of removing the stomach tube. Results The recovery of deglutition function in the experiment group was much better than that in the control group , the total effective rate and rate of removing the stomach tube within 3 months were higher and the intubation duration was significantly lower as compared with those of the control group (P < 0.01). Conclusion Rehabilitation training can improve the recovery of deglutition disorders, improve active feeding ability of children with cerebral palsy, shorten time of tube feeding and improve their life quality.

Objective To investigate the clinical significance of homocysteine(Hcy) and glycated hemoglobin (HbA1c) in patients with diabetic retinopathy.Methods From March 2013 to February 2015,a total of 168 patients with diabetes from Beijing Jishuitern Hospital were divided into diabetic retinopathy group (76 cases,32 male,44 female,average age 62.97 ± 12.46) and non-diabetic retinopathy group (92 cases,46male,46 female,average age 58.14 ± 13.71),and 65 cases of healthy subjects (46male,46 female,average age 60.24 ± 10.85) were enrolled as normal control group as well.Hcy and HbA1c were detected in all groups.Multiple independent samples nonparametric tests were used to compare the difference between groups.The concentrations of Hcy and HbA1c between DR group and NDR group were analysised by ROC curve analysis.Result The Hcy levels in normal control group,NDR group and DR group were 7.00 (4.55-10.50) μmol/L,12.45 (10.30-15.10) μmol/L,20.10 (16.63-25.68) μmol/L respectively.The HbA1c levels in normal control group,NDR group and DR group were 5.30 (5.00-5.70) %,6.80 (5.83-8.03) %,7.25 (6.50-8.60) % respectively.There was no significant difference in Hay and HbA1c levels between groups (P < 0.01);Compared with non-diabetic retinopathy group,levels of Hcy,HbA1c in diabetic retinopathy group were obviously higher;The optimal diagnostic cut-off values of Hcy was 14.35 μmol/L,at this cut-off value,the sensitivity was 96.05%,specificity was 68.48%;The optimal diagnostic cut-off values of HbA1c was 6.05%,at this cut-off value,the sensitivity was 98.68%,specificity was31.25%.Conclusion Patients with Diabetic retinopathy might have hyperhomocystinemia,and detection of Hcy may contribute to the early diagnosis of diabetic retinopathy.
