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 investigate the changes of fractional exhaled nitric oxide (FENO)) and their relation with lung function in bronchial asthma.Methods FENO and forced expiratory volume in the first second (FEV1) were measured during the periods of acute onset,chronic persistence and paracmasis in 54 patients with asthma and 19 healthy persons.Results There were significant differences in the levels of FENO and FEV1 among the course of acute onset [(57.59 ± 32.24) ppb and (1.72± 0.33) L],chronic persistent course [(40.02 ± 15.68) ppb and (2.41 ± 0.23) L],paracmasis [(26.71±6.07) ppb and (2.82±0.29 )L]and control[(14.74±3.42 ) ppb and (2.93±0.13)L] (F=19.555,163.096,P＜0.01) except for the levels of FEV1 between paracmasis and control group(P＞0.05).The negative correlation between FENO and FEV1 was found in the course of acute onset(r=- 0.666,P =0.005 ),but not in the chronic persistent course ( r =- 0.288,P =0.176) and paracmasis(r=-0.246,P=0.457).Conclusions The level of FENO is increased and may be useful to evaluate control degree in patients with asthma.

Objective To explore the value of hydronephrosis volume measured by 64 slice CT scan, evaluating renal function in patients with obstructive hydronephrosis.Methods The patients performed with both single photon emission computed tomography(SPECT) renal dynamic imaging and 64 slice CT scan in three days were chosen, 176 cases included finally.The images of renal dynamic imaging were divided into normal renal function group, mild renal impairment group, moderate renal impairment group and severe renal impairment group according to glomerular filtration rate (GFR) measured by SPECT.At the same time, CT three-dimensional reconstruction technique has been used to measure the volume of hydronephrosis, compare the differences of hydronephrosis volume among these groups, and future analyze the correlation of hydronephrosis volume with renal GFR value.Results The hydronephrosis volume of the four groups were respectively (31.47±3.81) cm3,(83.43±7.81) cm3,(208.53±15.47) cm3 and (577.31±61.32) cm3.There was statistical significance among these groups (P<0.01),except between normal renal function group and mild renal impairment group.The volume of hydronephrosis showed positive correlations with renal GFR (r=-0.614).Conclusion The volume of hydronephrosis measured by 64 slice CT has positive correlation with GFR measured by SPECT, which could reflect renal function to some extent.

Neonatal pain is a common phenomenon. For a long time neonatal pain had not been focus on properly and managed appropriately. American Academy of Pediatrics Committee on Fetus and Newborn and Section on Anesthesiology and Pain Medicine published policy statement to emphasize the necessity of neonatal pain assessment,and summarize the neonatal operability pain assessment method,drug and non-drug control measures,also update prevention and management of procedural pain in the neonate in 2016. Until today the guideline for neonatal pain management has not yet been released in China. As the reference for clinicians in domestic,the content of policy statement will be reorganized and introduced.

Objective To verify the correlation between rs17118 polymorphism of xyluloknase homolog (XYLB) gene and risk of ischemic stroke in a Chinese Han population.Methods A case-control study design was used.The case group was the patients with first-ever ischemic stroke and the control group was the healthy subjects from hospital physical examination.Taqman probe fluorescence quantitative polymerase chain reaction technique was used to detect the genotype distribution of rs17118 C/A polymorphisms.Results A total of 475 patients with ischemic stroke and 483 controls were enrolled in the study.The proportion of hypertension (67.9％ vs.22.2％;x2 =292.982,P ＜ 0.001) and diabetes (24.2％ vs.7.3％;x2 =25.864,P ＜ 0.001),as well as the levels of triacylglycerol (1.649 ± 1.126 mmol/L vs.1.157 ±1.480 mmol/L;t=3.592,P＜0.001),and low-density lipoprotein cholesterol (3.499 ± 1.163 mmol/L vs.3.105 ± 0.627 mmol/L;t =-6.227,P ＜ 0.001) in the case group were significantly higher than those in the control group,but the total cholesterol level was significantly lower than that in the control group (5.144 ± 1.296 mmol/L vs.5.491 ± 1.335 mmol/L;t =4.650,P ＜ 0.001).The AA genotyp e (11.4％ vs.7.5 ％;x2 =6.136,P =0.016) and A allele (32.3 ％ vs.26.4％;x2 =8.093,P =0.005) frequencies in the case group were significantly higher than those in the control group.Multivariatelogistic regression analysis showed that after adjusting for traditional risk factors,the risk of ischemic stroke in AA genotype carriers was 1.97 times of the CC genotype carriers (odds ratio 1.971,95％ confidence interval 1.040-3.736,P=0.038).Conclusions The rsl7118C/A polymorphism of XYLB gene may be associated with the risk of ischemic stroke in the Chinese Han population.
