Objective To investigate the prognostic factors of EGC patients,especially the relationship between prognosis and tumor size.Methods Clinical data of 119 EGC cases from 1998 to 2002 were analyzed retrospectively.Results The overall 5-year survival rate was 90.9%.and the survival rate of patients with tumor D＜2 cm.2 cm≤D＜4 cm and D≥4 cm respectively was 100%,92.0%and 80.8%(P=0.024).In this group,tumor stage,lymph node metastasis and tumor invasion depth did not affect the survival statistically.There was no correlation between tumor size and other prognostic factors.Conclusion Tumor size is an independent prognostic factor of patients with EGC,which may have some relevance to the surgical approach of EGC.

Objective:To investigate the neuroimaging relationship between tau protein deposition and brain atrophy, and assess their relationships with cognitive decline in Alzheimer′s disease (AD) patients.Methods:From April 2017 to October 2019, 26 AD patients (12 males, 14 females, age (70.7±12.2) years) and 19 cognitively normal controls (CN; 9 males, 10 females, age (65.6±8.1) years) in Chinese PLA General Hospital were retrospectively enrolled. All subjects received (S)-6-[(3- 18F-fluoro-2-hydroxy)propoxy]-2-(4-methylaminophenyl)quinoline ( 18F-THK5317) PET/MR and the standardized uptake value ratio (SUVR) and gray matter volume (GMV) were measured. General linear model (GLM) was used to evaluate the differences of SUVR and GMV between two groups. Pearson correlation analysis was used to assess the relationships between SUVR and GMV, and relationships of SUVR and GMV with Mini-Mental State Examination (MMSE) scores in AD patients. Results:Compared with CN, the AD patients showed significantly increased 18F-THK5317 retention in lateral temporal, frontal, posterior cingulated/precuneus and occipital cortex with significant differences of SUVR between two groups (2.18±0.54 vs 1.78±0.09, 2.13±0.50 vs 1.82±0.06, 2.03±0.45 vs 1.69±0.08, 2.18±0.57 vs 1.76±0.10, t values: 2.58-6.57, all P<0.001). The AD patients also showed decreased GMV in medial temporal, posterior cingulated/precuneus and orbitofrontal cortex ( t values: 3.67-8.85, all P<0.001). In AD patients, SUVR was negatively associated with GMV in bilateral lateral temporal cortex, pre-frontal cortex and orbital frontal cortex ( r values: from -0.52 to -0.43, all P<0.05). Both SUVR ( r=-0.599, P=0.001) and GMV ( r=0.443, P=0.023) were significantly correlated with MMSE scores in AD patients. Conclusion:AD patients have neocortical 18F-THK5317 abnormal uptake and GMV reduction, which are significantly correlated with cognitive decline.

Objective To investigate the empathic abilities and the association between empathic abilities and executive function in schizophrenic patients. Methods Empathy with the Interpersonal Reactivity Index-C (IRI-C) and executive function with Wisconsin Card Sorting Test (WCST) , Stroop Color-Word Task (Stroop), Spatial n-back Task (n-back) were applied to 74 schizophrenic patients and 69 healthy controls. Results Compared with healthy controls, schizophrenic patients showed significantly lower total scores ((46. 8 ± 10. 0) vs (51.5 ±9.7), P<0.01),and subscores in Perspective Taking ((9.5 ±4.2) vs (12.2 ±3.9) , P<0. 01), Fantasy ((12.5 ±4.2) vs (15.5 ±3.8), P<0.01) and Empathic Concern((15. 9 ±4.2) vs (17. 3 ±3.4), P< 0.05) ,but higher subscore((8.8 ±5. 1) vs (6.5 ±3.7), P<0.01) in personal distress of IRI-C. A significant difference(P<0.01) were fund on the scores of WCST, Stroop task and n-back task between schizophrenic patients and healthy controls. Pearson correlation analysis showed that the total scores of IRI-C was negatively correlated with the response administered (Ra), the number of responses errors (Re) and non-perseverative errors (nRpe) of WCST (r= -0.293, r= -0.253, r= -0.272, P<0.05) respectively, that empathic concern sub-score of IRI-C was negatively correlated with Ra, Re, perseverative responses (Rp) and perseverative errors (Rpe) of WCST (r= -0.326, r= -0.300, r= -0.294, r= -0.287, P<0.01 -0.05) respectively , but positively correlated with Rfp. of WCST (r=0.279, P<0.05), and that the fantasy subscore of IRI-C was negatively correlated with the reaction time of B part(r= -0.299, P<0.01) and C part (r= -0.322, P<0.01) of the Stroop task. Conclusion Schizophrenics have a general impairment of empathy and executive function,and affective empathy is related to the executive function, suggesting that the impairment of executive function maybe the one of pathological mechanism for the empathic deficit of patients with schizophrenia.

OBJECTIVETo observe the effects of Pogostemon cablin (Blanco) Benth. (PCB), a Chinese aromatic herbal medicine, on serum levels of nitric oxide (NO), tumor necrosis factor-alpha (TNF-alpha), and membrane fluidity of intestinal epithelial cells (IMC) in rats undergoing lower limbs ischemic reperfusion (I/R), for exploring its action in protecting intestinal barrier and the possible mechanisms, and to seek a new way, viewing from Chinese medicine, for providing the experimental bases of gastrointestinal protection against trauma or surgical operation.

METHODSEighty adult Wistar rats were induced into lower limb I/R model and randomized equally into the model group, the three PCB water extract groups treated respectively with high- (4 g x kg(-1) x d(-10), middle- (3 g x kg(-1) x d(-1)), and low-dose (2 g x kg(-1) x d(-1)) of PCB water extract, and three PCB volatile oil groups treated respectively with high- (4 g x kg(-1) x d(-1)), middle- (3 g x kg(-1) x d(-1)), low-dose (2 g x kg(-1) d(-1) of PCB volatile oil. Besides, 10 healthy rats was allocated in a normal control group. PCB preparation was given via gastric infusion for 5 successive days just before modeling. The serum levels of NO and TNF-alpha were monitored, and the membranous fluidity of IMC at I/R region was determined by fluorescence polarization technique.

RESULTSCompared with the control group, both serum NO and TNF-alpha levels in model rats were significantly higher (P < 0.01), and the fluorescence polarization value (P) of IMC obviously increased at the same time (P < 0.05). As compared with the model group, the serum level of NO and TNF-alpha significantly reduced in all the PCB treated groups (P < 0.01 or P < 0.05). As for the membrane fluidity, significant difference was shown between the model group with low-dose of PCB water extract and middle-dose of PCB volatile oil (P < 0.05).

CONCLUSIONPCB could effectively protect the intestinal barrier function by way of maintaining the membrane fluidity of IMC through regulating the level of NO and TNF-alpha in serum.

Objective To investigate the preventive effect of Indomethacin for post-ERCP pancreatitis and hyperamylasemia.Methods A total of 600 patients,who were undergoing ERCP,were randomly divided into 3 groups to receive anal Indomethacin (n=200),intravenous octreotide (n=200) or no special medication (n=200) before ERCP.The level of serum amylase before and 24h after ERCP were measured,and the rate of acute pancreatitis and hyperamylasemia after ERCP were assessed.Results Serum amylase levels before ERCP of all groups were normal.The mean serum amylase level of Indomethacin group (101.3±77.7 U/L) after ERCP was significantly lower than those of octreotide group ( 176.6±138.3 U/L,P =0.040 ]and control group (227.2±264.9 U/L,P=0.048),while there was no difference between octreotide group and control group ( P＞0.05 ).The incidence of post-ERCP pancreatitis in Indomethacin group (2.5％) was significantly lower than that of control group (9.5％,P=0.003),while there was no difference between octreotide group (4.5％) and control group ( P=0.05 ).The incidence of hyperamylasemia after ERCP in Indomethacin group (5.5％) was significantly lower than that of control group ( 13.5％,P=0.006 ),while there was no difference between octreotide group (10.0％) and control group ( P＞0.05 ).Conctusion Anal administration of Indomethacin before ERCP can effectively reduce the incidence of acute pancreatitis and hyperamylasemia after ERCP.

Objective To summarize our preliminary experience of selective fetieide with bipolar coagulation in complicated monochorionie twins(MCT),and discuss the clinical application of feticide in discordant MCT.Methods Three MCT with one twin anomaly.in which 2 had severe twin-twin transfusion syndrome(TTTS),stage Ⅳ ,and 1 had acardiac twin,were identified in the second trimester of pregnancy.To terminate the abnormal twin and isolate the co-twin's circulation completely.selective feticide was performed by umbilical cord occlusion with bipolar coagulation under guidance of ultrasound and fetoscopy.After each invasive procedure,serial monitoring was performed,including procedural complications,Doppler of fetal middle cerebral artery and umbilical artery.Pregnancies were followed up every 2 weeks for fetal growth until delivery.After birth the placentas and the terminated fetuses were examined.Result Cord occlusion was successfully accomplished in all 3 targeted fetuses,at 21,22 and 24 weeks of gestation respectively.One case with TTTS was complicated with rupture of the membrane in the terminated fetus at the 7th day after the procedure.and a healthy baby was born at 32 weeks.The other case with TTTS delivered a boy by cesarean section at 38 weeks.The third case with TRAP is at 35 weeks of gestations and under regular follow-up.Monochorionicity was confirmed by placental examination after delivery.and the effects of bipolar coagulation were observed at the,cord of terminated fetuses.Conclusions Umbilical cord occlusion witll bipolar coagulation is an effective procedure for selective feticide in MCT with one twin anomaly.The outcome of normal fetus can be favorable.

Objective To analyze the correlation of hypersensitive C-reactive protein(hs-CRP),homocysteine(Hcy) and D-dimer(D-D) with pathological change degree of coronary heart disease(CHD),and to investigate the diagnostic specificity and sensitivity of joint detection in CHD.Methods A total of 100 cases of CHD patients(experimental group) and 100 healthy subjects(control group) were enrolled,.Patients of the experimental group were divided into four groups on the basis of complications,including simple CHD group(32 cases),amalgamating hypertension group(46 cases),amalgamating diabetes group(9 cases),amalgamating hypertension diabetes group(13cases).The levels of hs-CRP,Hcy and D-D in the five groups were detected and analyzed.Results The levels of hs-CRP,Hcy and D-D in the experimental group were all higher than the control group(P<0.05).Logistic regression confirmed that three indexes were the independent risk factors for CHD.Each indicator has a certain clinical significance to the diagnosis and treatment of CHD but the value of Hcy could be better.Joint detection of hs-CRP and Hcy could be an ideal combination of detection,and the three joint detection might not be suitable for early diagnosis and treatment of CHD.The levels of hs-CRP and D-D in simple CHD group,amalgamating hypertension group,amalgamating hypertension diabetes group were all higher than amalgamating diabetes group(P<0.05).Conclusion hs-CRP,Hcy and D-D could be the independent risk factors of CHD,and joint detection might be with important clinical value for diagnosis of CHD.
