Objective To study the relationship between the 18F-FDG PET/CT whole body imaging characteristics and pathologic features of small intestine primary malignant neoplasms.Methods A retrospective study was carried out on 18F-FDG PET/CT data of patients(n =44)with small intestine disease(25 malignant,19 benign).All results were proved by pathologiy,or diagnostic therapy and/or clinical follow-up.The intestinal wall thickness(IWT)and maxium standardized uptake value(SUVmax)were used to analyze the imaging features under different pathological conditions.Results(1)The incidence rate of local tumor formation for benign and malignant intestinal lesions was 31.6％ and 84.0％(x2 =10.40,P ＜ 0.01),respectively.The IWT was(0.75 ± 0.32)cm and(1.42 ± 0.20)cm(t =2.66,P ＜ 0.01),respectively.The S UVmax was(5.17 ± 3.04)and(9.65 ± 5.48)(t =2.88,P ＜ 0.01),respectively.The incidence rate of enlargement of mesenteric lymph nodes for benign and malignant intestinal lesions was 52.6％ and 72.0％(x2 =1.01,P ＞ 0.05),respectively.The SUVmax was(4.80 ± 1.91)and(7.00 ± 5.61)(t =1.11,P ＞ 0.05),respectively.(2)The metastasis incidence rate of other organs for intestinal malignant lesions was 44.0％.The most common metastasis organs were liver(28.0％),distant lymph nodes(20.0％)and bone (16.0％).The most pathological type of intestinal malignant lesions were malignant lymphoma(44.0％),adenocarcinoma(32.0％).The IWT was(1.41 ± 0.59)cm and(1.36 ± 0.62)cm(t =0.18,P ＞ 0.05),respectively.The SUVmax was(12.49 ± 7.00)and(7.93 ± 2.82)(t =7.55,P ＜ 0.01),respectively.The metastasis incidence rate was 9.1％ and 62.5 ％(x2 =3.89,P ＜ 0.05),respectively.(3)Taking the intestinal local tumor formation and SUVmax andnot less than 4.2 0 wall thickening,and / or metastasis as the main basis of the intestinal malignant lesions,the sensitivity,specificity and accuracy were 96.0％,94.7％ and 95.4％,respectively.The main pathological type of false positive for '8F-FDG PET/CT imaging was intestinal tuberculosis,and false negative was signet(f)ing cell carcinoma.Conclusion 18F-FDG PET/CT imaging has a higher clinical diagnosis value in differentiating small intestine primary malignant carcinoma from benign ones.The size and SUVmax of perifocus lymph nodes could not point out its malignant degree.The 18F-FDG uptake of the lesions is correlated with pathological type.The IWT is not correlated with pathological type.

Objective To evaluate the value of whole body 18F-FDG PET/CT in detecting small intestine adenocarcinoma (SIA).Methods A retrospective study of 18F-FDG PET/CT was performed on 29 cases (male 17,female 12) of SIA,21 cases of small intestine lymphoma (SIL) (male 15,female 6) and 10 cases of small intestine tuberculosis (SIT) (male 4,female 6).Visual and semi-quantitative methods (SUVmax) were used to summarize and analyse the 18F-FDG PET/CT resutls.One-way analysis of variance and x2 test were used to analyze the data.Results (1) 18F-FDG PET/CT for SIA showed a partially conglomerate pattern of hypermetabolic small bowel masses with nodular configurations.A typical SIL showed a partially annular abnormal growth with aggregated foci of radioactivity.SIT lesions were usually in form of stripes and/or nodules with high metabolic foci or lesions withskipped distribution.The SUVmax of SIA (8.44±3.82) was significantly lower than that of SIL (11.54±4.02; F=86.96,t=2.77,both P＜0.01),but not significantly different when compared with SIT (8.61±2.99; t=0.11,P＞0.05).(2) The incidence rates of peri-lesion lymph node enlargement in SIA,SIL and SIT were 72.41％ (21/29),85.71％ (18/21) and 70.00％ (7/10),respectively (x2 =1.50,P＞0.05).The SUVmax of peri-lesion lymph nodes in SIA (5.59±2.86) was significantly lower than that of SIL (11.10±5.72; F=56.56,t=3.85,both P＜0.01),but was not significantly different when compared with SIT (5.63± 3.36; t =0.30,P＞ 0.05).The detection rate of PET/CT on pefi-lesion lymph node enlargement of SIA was higher than CT (41.38％,12/29; x2 =5.69,P＜0.05).(3) The incidence rate of extra-intestinal metastases was 55.17％ (16/29) in SIA,and the most common metastatic sites were liver,bone and adrenal gland.The incidence rate of extra-intestinal lesions was 66.67％ (14/21) in SIL,most commonly presented as widespread multifocal nodal permeation.Extra abdominal tuberculous loci were found in 80.00％ (8/10) of SIT.The incidence rates of extra-intestinal involvement were not significantly different among SIA,SIL and SIT (x2=2.13,P＞0.05).(4) Among the 29 SIA cases,15 (51.72％) involved the ileum,8 (27.59％) jejunum,4 (13.79％) both jejunum and ileum,and 2 (6.90％) both jejunum and duodenum (x2 =18.16,P＜0.01).(5) Among the 29 SIA cases,primary SIA was found in 8 cases (27.59％),double primary in 7 cases (24.14％) and metastatic SIA in 14 eases (48.28％).(6) Based on the clinical data,pathological results and clinical follow-up,the diagnosis of SIA by 18F-FDG PET/CT had a sensitivity and specificity of 93.10％ (27/29) and 80.00％ (8/10),respectively.Conclusions 18F-FDG PET/CT is useful for the differential diagnosis of S1A and for supporting the diagnosis of single primary,multi-primary and metastatic SIA.

Objective To determine the sensitivity of autofluorescence bronchoscopy (AFB) in the assessment of tumor size and therapeutic strategy.Methods Patients with imaging suspected of malignancy were examined with both white light bronchoscopy (WLB) and AFB.The area of tumor infiltration,imaging information and pathological results were analyzed.Results A total of 212 patients were enrolled,including 180 male and 32 female.In 24 patients (13.2％),greater tumor volume was revealed by AFB than by WLB alone.In these patients,the median diameter of tumor was ＞ 1 cm wider on AFB examination than on WLB.Therapeutic strategy was changed in 18 patients (9.9％) after receiving AFB,including 15 patients with expanded scope of removal and 3 patients with avoidance of surgery.In the univariate analysis,the pathological type of squamous cell carcinoma and tumor invasion in two or more segments of bronchus were independent predictive factors.Diagnostic sensitivity of AFB group was 85.7％,specificity 73.3％,positive predictive value 95.1％,false predictive value 45.8％.Diagnostic sensitivity of WLB group was 72.5％,specificity 60.0％,positive predictive value 91.7％,false predictive value 26.5％.Conclusion Our study suggests that compared with WLB alone,autofluorescence bronchoscopy plus WLB significantly improves the diagnostic value and treatment outcome of central lung cancer.

As a widely accepted and convenient method,the Apgar score has been applied to assess the status of the newborn infants and the response to resuscitation since 1952.But the Apgar score has also been used inappropriately in infants to predict specific neurologic outcomes in many cases.The Apgar Score produced by American Academy of Pediatrics(AAP) in collaboration with American College of Obstetricians and Gynecologists(ACOG),updated policy statements of the Apgar score in October 2015.The Apgar score has limitations,and it is not appropriate to use it alone to establish the diagnosis of asphyxia;the method does not predict individual neonatal mortality or neurologic outcome.AAP/ACOG encourages the use of an expanded Apgar score reporting form that accounts for concurrent resuscitation interventions.

Neonatal hypoxic-ischemic encephalopathy as a standard term has been used for over 30 years,but now increasingly being questioned.Most experts recommend using neonatal encephalopathy instead of hypoxic-ischemic encephalopathy.The American College of Obstetricians and Gynecologists and The American Academy of Pediatrics published separately the report of Task Force on Neonatal Encephalopathy Neonatal Encephalopathy and Neurologic Outcome,Second Edition in 2014.Definition,diagnosis and treatment of neonatal encephalopathy and other content have been updated in the report.It is recommended that a comprehensive multidimensional assessment be performed of neonatal encephalopathy.This article will introduce the controversy about neonatal encephalopathy or hypoxic-ischemic encephalopathy and contents of the report of Task Force on Neonatal Encephalopathy.

Bronchiolitis is a common lower respiratory tract viral infection in infants.Incidence of bronchiolitis is greatly increasing in recent years,and seriously affecting the health of children.In order to better manage bronchiolitis,American Academy of Pediatrics (AAP) convened a new subcommittee to review and revise the 2006 bronchiolitis guideline.This evidence-based guideline amended to provide new evidence of diagnosis,treatment and prevention bronchiolitis for the clinician.
