Objective To explore the effects of isoflurane on blood plasma metabolites (BPM) and its correlation with cognitive dysfunction.Methods Thirty female Sprague-Dawley (SD) rats were randomly divided into two groups:rats in the control group (n =10) received 80％ oxygen for 2 hours (h);and rats in the isoflurane-treated group (n =20) were anesthetized with isoflurane and 80％ oxygen for 2 h.Cognitive functions were examined using a Y-maze test to explore the learning times of rats.The level of blood plasma metabolites was detected through gas chromatography-mass spectrometry (GCMS).Results The learning times of rats in the isoflurane-treated group was more than the learning times of rats in the control group [(70.75 ± 15.30) vs (45.40 ± 11.21),P ＜ 0.05].D-fructose,arabinofuranose,n-butylamine,and inositol significantly increased (P ＜ 0.05),respectively.Whereas,L-analine and L-proline significantly decreased (P ＜ 0.05) in isoflurane-treated rats when compared to those in the control rats (P ＜ 0.05).Moreover,plasma concentrations of d-fructose,arabinofuranose,n-butylamine,inositol,and L-proline were positively correlated with the degree of cognitive dysfunction in the isoflurane-treated rats.Conclusions Changes of plasma concentrations of inositol,and d-fructose in aged rats are useful in predicting the occurrence and progression of post-anesthesia cognitive dysfunction.

Objective To evaluate the local control effect of radiotherapy and intravesical chemotherapy following bladder preserving surgery for musculoinvasive bladder cancer. Methods Twenty three patients with muscle invasive bladder cancer were treated by bladder preserving surgery followed by external radiation ( mean dose 52.5 Gy) combined with intravesical mitomycin infusion after bladder preserving operation (study group).For comparison, 29 similar patients received the same treatment without radiation served as control (control group).Results All patients in the study group completed their designed treatment,except two patients whose protocol was interrupted for 3 days and one week due to acute cystitis. The mean follow up duration was 41.6 months. The 3 year local recurrence rates were 18.8% in the study group and 44.8% in the control group(P=0.026).The 3 year distant metastasis rates were 18.2% and 24.1% (P=0.437),and the 3 year overall survival rates were 81.8% and 86.2% (P=0.670),respectively. Conclusion It is demonstrated that adjuvant radiotherapy and intravesical infusion chemotherapy following organ preserving surgical procedure are encouraging by giving favorable local control for musculoinvasive bladder cancer.

Objective To explore the correlative factors of sudden death in patients suspected with pulmonary thromboembolism (PTE) in emergency room (ER).Methods A retrospective analysis was conducted.The clinical data of 12 patients with sudden death suspected with PTE (sudden death group) in ER of the Air Force General Hospital from January 2011 to June 2014 were analyzed.The non-sudden death group included 35 patients during the same time period who were diagnosed with PTE based on findings of CT pulmonary arteriography (CTPA) and showed no sudden death in ER.Factors,including sex,age,previous operation,tumor,syncope,dyspnea,bilateral or unilateral edema of lower extremity,heart rate (HR),white blood cell count (WBC),D-dimer,arterial partial pressure of oxygen (PaO2),arterial partial pressure of carbon dioxide (PaCO2) and typical clinical manifestation of electrocardiogram (SⅠTⅢQⅢ),were compared between the two groups.The potential predictors of sudden death of PTE were analyzed by logistic regression analysis.Results Young age (years old:51.3±15.5 vs.62.3±14.4),lower PaO2 [mmHg (1 mmHg =0.133 kPa):49.9± 12.3 vs.62.7± 10.2],higher HR (bpm:122.0± 19.5 vs.89.1 ± 18.5) and higher WBC (× 109/L:13.8 ± 6.9 vs.7.2 ± 2.5) were found in sudden death group as compared with those in non-sudden death group (P ＜ 0.05 or P ＜ 0.01).There was no significant differences in D-dimer level and PaCO2 between sudden death group and non-sudden death group [D-dimer (pg/L):986 (891,3 230) vs.2089 (598,3 397),PaCO2 (mmHg):33.0 (28.6,43.4)vs.36.5 (32.9,41.0),both P ＞ 0.05].The syncope,antineoplaston treatment or tumor metastasis within 6 months,operation in previous 4 months,bilateral asymmetrical edema in sudden death group were more than those of the non-sudden death group,and chest pain was less (P ＜ 0.05 or P ＜ 0.01).Difference in gender,dyspnea and typical SⅠTⅢQⅢ in electrocardiogram were not significant between the two groups (all P ＞ 0.05).It was shown by multiple logistic regression analysis that higher HR [odds ratio (OR) =1.124,95％ confidence interval (95％CI) =1.024-1.235,P =0.014] and higher WBC (OR =1.347,95％CI =1.043-1.738,P =0.022) were identified as independent risk factors of sudden death for PTE.Conclusions Gender,dyspnea,typical S Ⅰ TⅢQⅢ in electrocardiogram,PaCO2 and D-dimer seem unrelated to sudden death of patients with PTE.Young age,chest pain,syncope,bilateral asymmetrical edema,antineoplaston treatment or tumor metastasis within 6 months,operation in previous 4 months and low PaO2 were potential predictors of sudden death according to the univariate analysis.Higher WBC and higher HR are independent risk factors of sudden death for PTE patients.

CONCLUSION: The prepared EPI-SLN is up to the standard.

ObjectiveTo explore the correlation between the respiration-induced clinical target volume (CTV) motion and volume variation and the dosimetric variation of planning target volume (PTV) and organs at risk (OAR) during free-breathing (FB) with whole breast intensity-modulated radiotherapy (IMRT).MethodsSeventeen patients with breast conserving surgery underwent respiration-synchronized four-dimentional computed tomography (4DCT) simulation scans on the state of FB.The treatment plan was constructed using the end-inspiration phase scan,then copied and applied to the other respiratory phases.The dose distribution was calculated separately to evaluate the dose-volume histograms parameters for the PTV,ipsilateral lung and heart.ResultsDuring FB,the CTV motion vector was (2.09 ±0.74) mm,and the volume variation was (3.05 ± 0.94) ％.There was no correlation between the volume variation of CTV and dosimetric variation of PTV/OAR ( r =-0.390 -0.480,P =0.182 -0.775 ).In anteroposterior (AP),superoinferior (SI) and vector directions,the CTV movement correlated well with the PTV mean dose,conformal index,and the lung volume receiving high dose (V20,V30,V40,and V50;r=-0.975-0.791,P =0.000 -0.041 ).In SI and vector directions,the CTV displacement only correlated with the heart volume receiving ＞ 5 Gy ( V5 ) ( r =-0.795,0.687,P =0.006,0.028 ).The lung volume variation and the lung volume receiving high dose correlated reasonably well (r=0.655 -0.882,P=0.001-0.04 0).The heart volume variation only correlated with the V5 of heart (r =-0.701,P =0.024).ConclusionsDuring free-breathing,the effect of breast volume variation can be ignored for whole breast IMRT,and whole breast IMRT assisted with breath-hold may improve the accuracy of dose delivery during radiotherapy.

Objective To summarize the clinical experience of surgical treatment for complete atrioventricular septal defect in infants.Methods From December 2013 to June 2004,56 patients aged from 53 days to 12 months with complete atrioventricular septal defect were undergone operations.All patients were diagnosed by 2D-echocardiography,and 18 patients underwent cardiovascular computed angiography (CTA).Rastelli type A had 44 cases,type B 3 cases,and type C 9 cases.The single pericardium patch repair was used for 37 cases,the two-patch repair for 3 cases,and the modified single-patch repair for 16 cases.The time of mechanical ventilation was 26 to 172 hours,and the time of staying at Intensive Care Unit (ICU) was 3 to 19 days.Results There were 5 early deaths caused by severe low cardiac output in 2 cases,renal failure in 2 cases,and severe pulmonary inflammation in 1 case.One late death was due to severe mitral regurgitation with pneumonia and heart failure.The operative mortality was 10.7％.A total of 47 patients was followed-up for 3 months to 5 years after surgery and their heart function was satisfactory.Conclusions The operation should be done between 6 months and 1 year when the diagnosis of complete atrioventricular septal defect (CAVSD) is clear.Its early surgical intervention is satisfactory.The result of surgical treatment for CAVSD depends on both probing intracardiac anatomy carefully and complete correction of associated cardiac abnormalities.

Objective To investigate the efficacy and safety of enriched-calorie formula in post-operative infants with congenital heart disease and malnutrition.Methods All malnourished infants less than 6 months diagnosed congenital heart disease: ventricular septal defect and had undergone surgery in Guangzhou Women and Children`s Medical Center from December 1,2014 to May 30,2015 were included in this study.All cases were randomly divided into intervention group(energy-enriched formula,intervention group)and control group(standard formula,control group)for enteral nutrition intervention and observed for 3 months.Body mass,body length,upper arm circumference,blood prealbumin(PA),retinol binding protein(RBP),and B-terminal pro-brain natriuretic peptide(NT-proBNP)were measured before and after ICU,after discharge,and 1 month and 3 months after operation.Results Fifty-one cases were in intervention group and 50 cases in control group,respectively.There were no significant differences in body mass,body length,arm circumference,PA,RBP,mean enteral nutrition starting time,mechanical ventilation time,length of ICU stay,hospitalization time,and average fluid intake between the two groups(all P>0.05).The average caloric intake in intervention group was significantly higher than in control group [(437.24±6.68)kJ vs.(312.43±86.22)kJ,P=0.001].There was no significant difference in NT-proBNP,PA,and RBP at different time points between the two groups(all P>0.05).The improvement of nutrition in intervention group was significantly higher than that in control group at 1 month(25.0％vs.4.9％,P=0.011)and 3 months(64.1％vs.15.7％,P<0.001)after operation.Body mass increased in intervention group [(0.067±0.348)kg] compared with that in control group,and decreased [(0.125±0.425)kg] in control group(P=0.015).Body weight[(5.46±1.36)kg vs.(4.80±1.01)kg,P=0.008],weight for age Z score(WAZ)(-2.79±1.28 vs.-3.75±1.27,P<0.001),and height for weight Z score(WHZ)(-2.47±1.43 vs.-3.62±1.77,P=0.001)one month after surgery were significantly higher than those before operation.Body weight [(6.78±1.42)kg vs.(5.72±1.01)kg,P<0.001] arm circumference [(12.80±1.17)cm vs.(12.00±0.90)cm,P<0.001],WAZ(-1.60±1.17 vs.-3.10±1.40,P<0.001),height for age Z score(HAZ)(-1.41±1.63 vs.-2.10±1.41,P=0.034),and WHZ(-0.86±1.31 vs.-2.59±2.13,P<0.001)of the two groups at 3 months postoperative were significantly higher than those before operation,and the growth rate of intervention group was faster than control group.There were no significant adverse reactions in both groups.Conclusion Calorie-enriched formula powder can help malnourished infants to catch up after congenital heart disease surgery.

Objective To investigate the effects of physical and chemical factors in the environment for dried blood sample (DBS) preparation of neonatal screening assay.Methods A total of 60 normal and 120 positive DBS were prepared under control and 10 different conditions.Another 30 normal and 80 positive DBS were prepared under control and 7 different concentration gradients of formaldehyde.The levels of phenylalanine (Phe),glucose-6-phosphate dehydrogenease (G6PD),thyroid stimulating hormone (TSH) and 17α-hydoxyprogesterone (17α-OHP) were tested by time-resolved fluorescence immunoassay or fluorescence assay.Statistical analysis was performed using SPSS 22.0 software.Results Compared with the control group,the results of Phe were not significantly different (P ＞ 0.05) when the samples were dried under the formaldehyde sensitive threshold (4.62 to 6.95 ppm for 18 hours).G6PD levels were significantly lowered when the samples were dried under all the conditions except for fast cold drying (2 to 8 ℃ overnight and formaldehyde condition,0.30 to 0.38 ppm for 4 hours or 0.21 to 0.24 ppm for 18 hours).TSH and 17α-OHP levels were lowered obviously when the samples were dried under the conditions of humidity,UV and formaldehyde condition (TSH:0.32 to 0.52 ppm for 4 hours,0.38 to 0.45 ppm for 18 hours,17α-OHP:4.37 to 4.62 ppm for 4 hours,0.38 to 0.45 ppm for 18 hours).The results of Phe,G6PD,TSH and 17α-OHP were not statistically different with the control group when the samples were dried under the fast cold drying and 2 to 8 ℃ overnight.Conclusion The physical and chemical factors in the environment of DBS preparation should be related to the accuracy of neonatal disease screening closely.The necessary control factors including formaldehyde,ethanol,glacial acetic acid,ultraviolet irradiation,heat,humidity and decoration pollution may exhibit significant effects on the preparation of DBS.Fast cold drying and overnight at 2 to 8 ℃ could be available for DBS preparation.

OBJECTIVETo investigate the expression of a new immunoglobulin gene SNC73 in malignant tumor and normal tissue and its significance.

METHODSExpression level of SNC73 in tumors and normal tissues was determined by reverse transcription-polymerase chain reaction and enzyme-linked immunosorbent assay (RT-PCR-ELISA) in 90 malignant tumors, including colorectal cancer, gastric cancer, breast cancer, lung cancer and liver cancer. Analysis on relation of SNC73 expression with age, sex, site, differentiation grade, depth of invasion and metastasis of colorectal cancer was made to assess the clinical significance of SNC73.

RESULTSMean ratio of SNC73 expression level in normal mucosa and colorectal cancer tissue was 7.134 (P < 0.01). Expression of SNC73 showed no significant difference among gastric cancer, breast cancer, lung cancer or liver cancer as compared with the control normal tissues (P > 0.05).

CONCLUSIONDown-regulation of SNC73 expression is a relatively specific phenomenon in colorectal cancer for which development SNC73 may be a potential genetic marker. The study on relationship of SNC73 expression with development of colorectal cancer is promising.
