Objective To investigate the expression of HSF2 in colonic mucosa of patients with ulcerative colitis (UC),Crohn's disease (CD),intestinal tuberculosis (ITB),intestinal lymphoma (IL),infectious enteritis,Behcet's disease and normal control.Methods Intestinal tissue samples were retrieved from 2003-2011 archived specimen at the Department of Pathology,and assigned to UC group (n =38),CD group (n =29),ITB group (n =31),IL group (n =32),infectious enteritis group (n =32) and Behcet's disease group (n =28).10 cases were recruited as normal control group.The expression of HSF2 in colonic mucosa were detected by immunohistochemistry.Positive cells were counted by Image Analysis.Results The expression rate of HSF2 in intestinal mucosa of UC patients (64.64 ± 15.17) was significantly higher than that of CD (32.44 ± 5.94),ITB (36.93 ± 6.32),IL (36.16 ± 6.55),infectious enteritis (37.86 ±7.76),Behcet's disease (34.90 ±5.92) and normal control (35.54 ±6.76) (P ＜0.05),while there was no significant difference among the latter six groups (P ＞ 0.05).Conclusion HSF2 is closely related with UC,and may play an important role in the pathogenesis,diagnosis and differential diagnosis of UC.

Objective To explore the relationship between left atrial diameters (LAD) and prothrombotic state in senile patients with hypertension (HT) and atrial fibrillation (AF). Mcthods Totally 105 patients with cssential hypertension were divided into 65 patients with atrial fibrillation and 40 cases without atrial fibrillation,and then patients with atrial fibrillation were subgrouped into paroxysmal and persistent atrial fibrillation groups.30 healthy people without hypertension and atrial fibrillation were used as control group.LAD was determined by M type ultrasound cardiogram.Fibrinogen (Fg),D-Dimer(D-Dimer),von willebrand (vwF) and haematocrit (HCT) were also measured as prothrombotic state and compared among the groups. Results In groups of HT with AF versus HT without AF versus control,LAD[(43.56 ± 6.72) mm vs.(36.28 ± 5.83) mm vs.(31.63±4.32)mm],Fg[(4.24±0.59)g/L vs.(3.09 ±0.49)g/L vs.(2.80± 0.46)g/L],D-Dimer [(0.43±0.13)mg/L vs.(0.28±0.]0)mg/L vs.(0.18±0.08)mg/L],vwF[(290.44±29.02)％ vs.(101.32±21.36)％ vs.(84.15±20.26) ％],HCT[(0.46±±0.07)vs.(0.37±0.05)vs.(0.34±0.03)]were significantly higher in HT patients with atrial fibrillation than those without atrial fibrillation and control ( all P＜ 0.05),and there were differences in LAD and D-Dimet (P＜＜0.05),but not in Fg,vwF and HCT (all P＞0.05) between patients without atrial fibrillation and control.LAD[(46.75±7.32)mm vs.(40.82±6.21)mm],Fg [(4.68±0.65)g/L vs.(3.85±0.53)g/L],D-Dimer [(0.48±0.16)mg/L vs.(0.40±0.12)mg/L],vwF [(384.96±29.75)％ vs.(209.43±28.63)％] and HCT [(0.49±0.08)vs.(0.43±0.06)] in persistent atrial fibrillation group were increased than those in paroxysmal atrial fibrillation group ( P ＜ 0.05 ).Fg ( r =0.683 ),D-Dimer ( r =0.735 ),vwF ( r=0.763) and HCT(r=0.759)were corrclated with LAD (all P＜0.01). Conclusions Increased LADmight he one of the elevated risks of atrial fibrillation and a higher prothrombotic state is increasing with larger LAD in senile hypertension.

Objective To retrospectively investigate the characteristics of patients with inflammatory bowel disease (IBD)in last 10 years in Kunming city. Methods Four hundred and thirty consecutive patients with IBD, who had hospitalized in 7 hospitals between January 1998 to March 2007, were investigated. Among them, 379 patinets had ulcerative colitis (UC) and 51 had Crohn's disease (CD). The patients who received coloscopy, histopathological and bariam enema examination accunted for 98.2%, 56.2% and 2.6% in UC group,respectively, and 72.5%,78.4% and 31.4% in CD group,respectively. The gender, age, occupation and the clinical manifestation of the patients, and the results of the colonoscopy and pathological examination were analyzed. Results Most of the UC patients were aged 30 to 39 years and 50 to 59 years with average age of (46.9±15.8) years, whereas CD patients were aged 20 to 29 years with average age of (41.6±17.2)years. The male and urban patients were predominat in both UC and CD groups. Mental workers were common in UC group. The symptoms of diarrhea (302,79.7%), abdominal pain (285,75.2%) and bloody stools (290,76.5%) were major events in UC patients, and those of abdominal pain (44,86.3%), diarrhea (28,54.9%) and weight loss (28,54.9%) were major events in CD patients. The coincidence ratio among colonoseopy, histopathology and bariam enema examinations was 88.4 % ( 329/372 ), 24.4 % ( 52/213 ) and 4/10 in UC patients, respectively, and 86.5%(32/37), 27.5%(11/40) and 75%(12/16) in CD patients, respectively. All of the UC patients were in active stage of disease,including 38.3 % in mild,42.2% in moderate and 19.5% in severe. In CD group, 7.8% was in relief stage and 92.2% in active stage,including 15.7% in mild,43.1% in morderate and 41.2% in severe.Conclusion The understanding of prevalence and clinical characteristics of IBD in last 10 years in Kunming city will be helpful in diagnosis and treatment of the disease.

Objective To investigate the effect of propofol pretreatment on the expression of phosphorylated c-Jun N-terminal kinase (p-JNK), matrix metalloproteinase-9 (MMP-9) and aquaporin-4 (AQP-4) during focal cerebral ischemia-reperfusion (I/R) in rats. Methods Seventy-two healthy male SD rats weighing 250-280 g were randomly divided into 4 groups (n = 18 each): sham operation group (group S), I/R group and propofol pretreatment group (P1 and P2). In group I/R, P1 and P2, focal cerebral I/R was induced by occlusion of middle cerebralartery for 2 h followed by 24 h of reperfusion. In group P1 and P2, intraperitioneal 0.5 % and 1% propofol 10 ml/kg were injected 30 rmin before ischemia respectively. In group I/R, normal saline 10 ml/kg was given instead of propofol 30 min before ischemia. Neurological deficit score (NDS) was assessed after consciousness was recovered. 2% Evans blue (EB) 3 ml/kg was injected intravenously 1 h before the animals were sacrificed at 24 h of reperfusion. The brain tissues were taken for determination of the brain water content, EB content and expression of p-JNK, MMP-9 and AQP-4. Results Compared with group S, the NDS and content of water and EB were significantly increased and the expression of p-JNK, MMP-9 and AQP-4 was up-regulated in group I/R, P1 and P2(P ＜ 0.05). Compared with group I/R, the NDS and content of water and EB were significantly decreased and the expression of p-JNK, MMP-9 and AQP-4 was down-regulated in group P1 and P2 (P ＜ 0.05). Compared with group P1 , the expression of p-JNK and MMP-9 was down-regulated (P ＜ 0.05), but no significant difference was found in the NDS, water and EB content and the expression of AQP-4 in group P2 (P ＞ 0.05). Conclusion Propofol pretreatment can reduce focal cerebral I/R injury by inhibiting the activation of JNK signal pathway and up-regulation of MMP-9 and AQP-4 expression.

Autoimmune encephalitis with GABAB receptor antibodies has been rarely reported.Two cases of GABAB receptor antibodies encephalitis were presented here.Epilepsy was the onset symptom,followed by declined consciousness and frequent seizures.Fever was presented in the whole course of the disease.Myorhythmia of the two hands and pilomotor seizures were shown in the later course of the disease.No specificity was demonstrated in electroencephalograms and magnetic resonance imaging.Sensitive response was shown to the first-line immunotherapy.

OBJECTIVE:To evaluate the efficacy and toxicity of paclitaxel combined with cisplatin in the treatment of advanced non-small cell lung cancer(NSCLC) by weekly-,biweekly- and three-weekly-regimens.METHODS:180 patients who had been confirmed by pathology and cytology as having NSCLC(Ⅲ～Ⅳstage) were enrolled into the study and divided to three groups:Biweekly - regimen(n= 60):paclitaxel 80 mg?m~(-2) plus cisplatin 40 mg?m~2 ivgtt on day 1 and day 8 in every 21 days;Weekly- regimen(n= 60):paclitaxel 55 mg?m~(-2) plus cisplatin 30 mg?m z ivgtt on day 1,8,and 15 in every 28 days;Three - weekly regimen(n = 60):paclitaxel 160 mg?m~(-2) plus cisplatin 80 mg?m~(-2) ivgtt on day 1 in every 21 days.Serum concentrations of paclitaxel at 3,12,24 h after administration were determined,and the efficacy and toxicity after two- cycle treatment were evaluated.RESULTS:The overall response rates of weekly-,biweekly -and three weekly regimens were 43.1%,35.8%and 34.0%respectively,showing no statistical differences among groups,but the incidence of main toxicities of biweekly-regimen was lower as compared with the other regimens.CONCLUSION:Biweekly -regimen is optimal for the treatment of advanced NSCLC with mild toxicity,which deserves to be applied in clinical practice.
