Objective To discuss the pathological classification and lesion's inner imaging features of lung adenocarcinoma presented as pure ground-glass opacity.Methods CT imaging features of 156 pGGO lesions which confirmed by surgery and pathology were analyzed in retrospectively.There were 58 lesions of pre-invasive (including atypical adenomatous hyperplasia and adenocarcinoma in situ),32 lesions of minimally invasive adenocarcinoma and 66 lesions of invasive adenocarcinoma.CT features were analyzed including lesion density,vacuole sign,air bronchogram and abnormal vascular changes (vascular dilatation,distortion or rigid).Results There were statistical difference in lesions density and abnormal vascular changes in 3 different pathological types (P ＜ 0.05),with increase of lesions invasive,the incidence of uneven density and abnormal vascular changes increase,its mean the more invasive of the lesion,the lesion tent to be more uneven and higher incidence of the dilation,twist or rigid of the vascular happened;while the incidence of the air bronchogram will be higher when the lesions invasive degree increased,but there was statistical difference only between the pre-invasive and invasive groups (including minimally invasive adenocarcinoma and invasive adenocarcinoma) (x2 =4.868,P =0.027).Conclusions The uneven density and abnormal vascular changes had certain value in differential diagnosis of lung adenocarcinoma presented as pGGO.

Objective To investigate the effects of Chaishao Chengqi Decotion on intestinal microbiota and intestinal mucosal lesion in severe acute pancreatitis(SAP).Methods 46 Patients with SAP were randomized into two groups.Routine medical management was initiated in two groups.The treatment group received Chaishao Chengqi Decotion for 1 week.The plasma concentrations ofDiamine Oxidase (DAO),D-lactate were detected and changes of microflora were evaluated by bacterial culture.Results The levels of DAO in the treatment group (4.65 ±0.82)U/ml were significantly lower than those in the control group (5.66 ±2.17) U/ml (P ＜ 0.05) 7 days after treatment.The levels of D-lactate in the treatment group (10.65 ± 5.24)mg/L were significantly higher than those in the control group (5.42±2.13)mg/L (P＜0.05).Bacterial culture revealed that the amount of bifidobaterium (6.02± 1.42)In/g and lactobacilli (7.21 ± 2.02) In/g were significantly increased when compared to those before treatment (3.74± 1.71)In/g and (4.03 ± 1.79)In/g respectively,while there was imbalance of intestinal microflora to some extent in the control group.Conelusien Chaishao Chengqi Decotion exerted the protective effects on gut barrier function by alleviating the damage of intestinal mucosa and balancing the intestinal microbiota following severe acute pancreatitis.

Objective To understand the situation of procrastination and its influencing factors in medical students.Methods The general procrastination scale (GPS),general self-efficacy scale (GSES),achievement motivation scale(AMS),self-esteem scale (SES),self-rating depression scale (SDS) and self-rating anxiety scale (SAS) were applied to 531 medical students,and the influence factors were analyzed with correlation analyses,hierarchical regression and path analysis of SPSS 16.0 and Amos 5.0.Results (1) The scale score of procrastination was between 31-93 and the average score was 55.54±9.68.96.1％ students showed different degree procrastination,with the moderate-severe degree ones accounted for 45.3％.(2)Procrastination was positively correlated to anxiety(r=0.331) and depression(r=0.415),but negatively correlated with self-efficacy(r=-0.247) and selfesteem(r=-0.328).(3)The hierarchical regression revealed that self-efficacy,self-esteem,and depression could significantly predict procrastination,which increased the explained variance 6.1％,6.1％ and 6.3％ respectively.(4) Path analysis showed that the self-esteem had direct effect on procrastination (path coefficient 0.12);self-efficacy had indirect effect on procrastination through self-esteem (path coefficient 0.21).Depression had direct effect on procrastination (path coefficient 0.34) and indirect effect to the procrastination through the self-esteem (path coefficient 0.50).All the fitting indices reached statistical standards.Conclusion Procrastination was common in medical students and self-efficacy,self-esteem,depression had direct or indirect effect on it.

To study the value of high-fluorescent cell for the screening of malignant hydrothorax or ascites. The clinical diagnosis results and hydrothorax or ascites specimens of 400 outpatients registered from January to December in 2014 were collected, and high-fluorescent cells were counted with Sysmex XE-5000 blood cell analyzer, and then stained for microscopy. Receiver operating characteristic (ROC) curve was used to explore the sensitivity, speci-ficity, positive likelihood ratio and negative likelihood ratio of high-fluorescent cell for screening malignant hydrothorax or ascites. The numbers of high-fluorescent cells of the cancer patients were significantly higher than those of the non-cancer patients, with Z equal to -7.372 and P less than 0.05. The values of the area under curve (AUC), sensitivity, specificity, positive likelihood ratio and negative likelihood ratio were 0.801, 70.67%, 84.31%, 4.50 and 0.35 respective-ly. Detection of high-fluorescent may be used to screen malignant hydrothorax or ascites, and further exami-nation and follow-up have to be performed in case the number of high-fluorescent cells in the hydrothorax or ascites is not less than 68.

Objective: To study the fluid distribution abnormalities in patients on hemodialysis and fluid shift between intracellular and extracellular compartment during hemodialysis (HD).Methods: Eighty stable end stage renal disease patients on maintenance hemodialysis were selected. Conventional low flux dialyses at dialysate sodium concentration of 138 mmoL/L were performed for all of the patients. Fresenius polysulphons or Gambro hemophon dialyzers were used. All of the patients showed no clinical signs of over ultrafiltration during HD sessions and dry body weights were considered adequate. Intracellular water (ICW), extracellular water (ECW) and total body water (TBW) were measured and standardized by body weight (nICW, nECW, nTBW) before and after HD sessions. Sixty-seven cases of sex, age and body weight matched normal individuals were used as controls. Bio-impedance spectrum (BIS) analysis (Xitron, Technolo gies, San Diego, CA, USA) was used in body fluid measurement. Pre and post HD nICW, nECW, and nTBW were compared with these of the controls.Results: There were no differences in age, post-dialysis body weight and body mass index between patients on hemodialysis and the controls. Patients on hemodialysis had less nICW [male (0.28?0.05) vs (0.33?0.04), P

Objective:To propose a method to evaluate the total body water (TBW) of patients on hemodialysis with urea kinetic model (UKM), and compare it with body surface bio-impedance spectrum (BIS) analysis. Methods:We enrolled 24 adult patients with end stage renal disease (ESRD) without hyper-catabolism in our dialysis center. All of them had been on hemodialysis for more than 3 months. TBW was measured with BIS analysis immediately before and after dialysis session, and one hour after hemodialysis session. Spent dialysate was collected; blood samples were taken before and one hour after hemodialysis session, TBW before hemodialysis session were calculated by UKM. Results:Patients were 6 men and 18 women, the average age was (51.2?13.5) years and the average time on dialysis was (33.2?36.7) months. Causes of ESRD included chronic glomerulonephritis (8 patients), diabetic nephropathy (1 patients), hypertensive renal damage (1 patients), interstitial nephritis(two patients), chronic pyelonephritis (two patients). The average ultrafiltration volume was (2.7?1.0) L (0.5-4.4 L) . Plasma urea concentrations were (23.06?5.76) mmol/L and (8.15?2.06) mmol/L before and one hour after hemodialysis session, respectively. There was no significant difference between TBW measured immediately after and one hour after hemodialysis session with BIS analysis [(29.9?8.8) L and (29.8?8.6) L, respectively; average difference was (0.1?0.9)L, P=0.70]. These two measurements correlated very well (Pearson r=0.99, P

Objective To investigate the distribution and antibiotic resistance profile of clinical isolates in the First Hospital of Qiqihar during 2015.Methods Antimicrobial susceptibility test was carried out according to a unified protocol using automated system from January 1,2015 to December 31,2015.The results were analyzed with WHONET 5.6 software according to the 2014 breakpoints of Clinical and Laboratory Standards Institute.Results A total of 5 162 clinical isolates were collected,of which 28.1％ (1 450/5 162) were gram-positive cocci and 71.9％ (3 712/5 162) were gram-negative bacilli.About 36.5％ (255/698) ofS.aureus isolates and 81.4％ (180/221) of coagulase negative Staphylococcus isolates were resistant to methicillin.No S.aureus and coagulase negative Staphylococcus isolate were found resistant to vancomycin or linezolid.Enterococcus isolates showed low resistance to vancomycin and linezolid.One strain of E.faecium was found resistant to vancomycin.ESBLs were produced in 39.9％ (298/747) ofE.coli,26.1％ (294/1 127) ofKlebsiella spp.,and 15.6％ (12/77) ofP mirabilis strains.The Enterobacteriaceae strains were less resistant to imipenem,beta-lactam/beta-lactamase inhibitor combination and amikacin.About 36.6％ (163 / 445) of A.baumannii isolates and 1.8％ (13/715) of P.aeruginosa isolates were extensively drug-resistant strains.Conclusions Antibiotic resistance poses a serious threat to clinical practice,to which more attention should be paid.Clinical microbiology lab should make more efforts to provide better support to clinical therapy.

Objective To explore the relationships between the quantitative parameters for contrastenhanced ultrasonography(CEUS) in hepatocellular carcinoma (HCC) and arteries in neoangiogenesis.Methods One hundred and fifteen HCCs in CEUS were analyzed off-line with dynamic vascular curve of ImageArena and immunohistochemical stained in the tissue slices.Parameters including maximum of intensity(IMAX),rise time(RT),time to peak(TTP),mean trasit time corresponding to the center of gravity(mTT) ,rise slope(RS) and washout time(WT) were analyzed by statistics.Unpaired arteries(UAs)of 82 HCC cases were succesfully stained.Results The number of UAs had moderate correlation with RT (r = - 0.446),TTP (r = - 0.432) and RS (r = 0.431) (P ＜ 0.05),and it had mild correlation with IMAX (r = 0.303) ,WT (r = 0.285) (P ＜0.05).Conclusions Neoangiogenesis is a functional adaptation to altered vascular dynamics.Quantitative parameters of CEUS,reflecting hemodynamics of tumors,are correlated with UAs.
