Objective To investigate the relationship between serum levels of D-dimer(DD),hs-CRP and IL-6 with the infarction severity and prognosis in the patients with cerebral infarction(CI),and to analyze the influencing factors of prognosis for screening the independent risk factors affecting prognosis.Methods Eighty-one patients with CI in our hospital from January 2014 to June 2015 were selected as research subjects.All patients were treated with the CI routine treatment after admission.On admission,the CI severity was assessed by NIHSS,the serum levels of DD,hs-CRP and IL-6 were detected.After discharge,following up lasted for 12 months,the prognosis was assessed by MRS scale.The correlation between DD,hs-CRP and IL-6 with the infarction severity and prognosis was analyzed.The prognostic influencing factors were analyzed by adopting the univariate analysis and multivariate Logistic regression analysis.Results On admission,the levels of DD,hs-CRP and IL-6 in the severe group were significantly higher than those in the moderate group(q=5.736,7.772,4.757,P<0.05) and the mild group(q=11.094,16.920,12.255,P<0.05),while the moderate group was significantly higher than the mild group(q=5.783,9.870,8.049,P<0.05).Pearson′s analysis showed that the levels of DD,hs-CRP and IL-6 were positively correlated with the CI severity(r=0.603,0.457,0.394,P<0.05).After following up for 12 months,the levels of DD,hs-CRP and IL-6 in the good prognosis group were significantly lower than those in the poor prognosis group(t=4.775,3.101,2.910,P<0.05).Pearson′s analysis showed that DD,hs-CRP and IL-6 levels were positively correlated with poor prognosis(r=0.584,0.513,0.432,P<0.05).Multiple Logistic regression analysis showed that infarct volume,NIHSS score,DD,hs-CRP and IL-6 were the independent risk factors for poor prognosis in the patients with CI(P<0.05).Conclusion The infarct volume,NIHSS score,DD,hs-CRP and IL-6 are the independent risk factors for poor prognosis in the patients with CI,which provide a certain reference for judging the prognosis in CI patients.

Objective To assess the association between serum levels of carbohydrate antigen 125 (CA125) and the heart function in the elderly with congestive heart failure (CHF). Methods CA125, carcinoembryonic antigen (CEA) ,alpha-fetoprotein ( AFP), CA199, CA15-3, CA724, liver and kidney function and NT-proBNP were measured in 178 patients with heart failure. Ve, Va, Ve/Va, left ventricular end-diastolic diamete ( LVEDD), left ventricular end-systolic diamete ( LVESD ), left ventricular ejection fraction ( LVEF ) and time were measured using echocardiograph. All patients were classified as Ⅰ + Ⅱ , Ⅲ and Ⅳ level according to the criteria of New York Heart Assocation ( NYHA), and the incidence of pleural effusion, peripheral edema,atrial fibrillation were observed. Results Among the 178 patients,serum CA125 were ≤35 U/ml in 91 patients with median of 9.9( 3.4 - 33.7 ) U/ml, ＞ 35 U/ml in 87 patients with median of 64. 4 ( 20. 2 - 462. 1 ) U/ml.Among those patients with CA125 ＞ 35 U/ml ,heart function was classified as level Ⅲ + Ⅳ in 82 patients,and level Ⅰ + Ⅱ in 5 patients. Among the patients with CA125 ≤35 U/ml,heart function was classified as level Ⅲ + Ⅳin 7 patients,and level Ⅰ + Ⅱ in 84 patients. Heart function was significantly different between the two CA125 groups( x2= 133. 3 ,P ＜0. 001 ). The incidence of pleural effusion,atrial fibrillation ,peripheral edema in the higher CA125 group were 32. 2%, 51.7% and 78. 2%, respectively, which were significantly higher than those in the normal CA 125 group ( 5.5 %, 9. 9% and 19. 8 %, repactively ) ( P ＜ 0. 01 ). NT-proBNP, LVESD,LVEF and time in the higher CA125 group were 2524. 0( 104.0 - 19 308. 0) ng/L,35 (27 -55) mm,49% (23%-66% ) and 268 (210 -312)ms, which were significantly differenct from those in the normal CA125 group [356.0 ( 32.0 - 5201.0) ng/L, 32 ( 26 - 53 ) mm, 59% ( 42% - 69% ) and 290 ( 260 - 340 ) ms, respectively](Ps ＜0. 05). The linear regression showed that serum CA125 was positively correlated with NT-ProBNP and urea nitrogen ( BUN ) ( r= 0. 3326 and 0. 3430, Ps= 0. 002 ) , as well as negtively correlated with LVEF and time (r= -0. 3016,P =0. 006;r = -0. 336,P =0. 004). Conclusion Serum CA125 in the elderly with congestive heart failure increased with the worsing of heart function, and correlated with the level of NT-proBNP, LVEF and time,as well as pleural effusion, atrial fibrillation, peripheral edema.

Objective　To explore the effects of treatment and mechanism of sodium salicylate on blast deafness. Methods　Guinea pigs were divided into blast group, blast plus sodium Salicylate group and sodium solicylate group. The animals in the blast group were exposed to blast average peak pressure 176.7 dB(SPL); sodium salicylate was injected IP 400 mg/kg,1/d. Monitoring ABR threshold, the value of MDA of and counting the number of hair cells on the cochlea preparation, SEM for hair cells was observed. Results　The ABR threshold shift in the blast group was 46.75±13.56 dB，38.0±12.4 dB,35.5±10.67 dB，41.5±12.57 dB,33.75±8.42 dB, post-blast 1 d，3 d，1 w，2 w,4 w respectively. And that of the blast plus sodium salicylate was 46.65±11.7 dB，38.25±9.52 dB,30.5±9.17 dB,30.0±9.17 dB,23.0±6.57 dB. The two groups differed significantly at 1 w，2 w，4 w(P＜0.05). The value of MDA differed significantly at 2 w,4 w(P＜0.05). And the hair cells lost also differed significantly. It was observed that sodium salicylated can raise the ABR thresbold temporarily 24 hrs during simple sodium salicylate adminastration. However it recovered 14 hrs after the injection.Conclusion　Sodium salicylate can partially attenuate the hearing loss caused by blast. It is probable that sodium salicylate can clear peroxicative produced during blast and therefore protect hair cells and make hearing loss partially recover.

Objective To analyze the clinical significance of aberrant hepatic artery which originated from superior mesenteric artery in liver cancer and gastric cancer operations.Method Four hundred liver cancer patients who underwent digital subtraction angiography (DSA) and multislice spiral computed tomography angiography (MSCTA) and 86 gastric cancer patients who underwent MSCTA between June 2008 and June 2010 and operated at the First Affiliated Hospital of Guangxi Medical University were included in this study.Preoperatively,the origins of the aberrant hepatic arteries from superior mesenteric arteries were detected by medical imaging.Postoperatively,immunohistochemistry of lymphoid tissues around the aberrant hepatic arteries of the gastric cancer patients were performed using recombinant human cytokeratin 20 (CK20) and carcino-embryonic antigen (CEA) to determine the incidence of lymph node metastases around the aberrant arteries.Results Among 486 patients,49 patients with liver cancer and 14 patients with gastric cancer had an aberrant hepatic artery which originated from the superior mesenteric artery.The rate was 12.96％ (63/486).The hepatic artery ran in front of the pancreas in 2 patients (3.17％) and behind the pancreas in 61 patients (96.83％).Immunohistochemical analyses of CK20 and CEA were negative which revealed no metastases in the lymphoid tissues surrounding the aberrant arteries.Conclusions Aberrant hepatic artery originated from the superior mesenteric artery can be classified into the pre-pancreas type and postpancreas type.The majority of aberrant hepatic artery belonged to the post-pancreas type.The clinical significance of aberrant hepatic artery is that the hepatic hilar lymph nodes should be dissected in liver cancer and gastric cancer operations.

Objective To investigate the clinical and pathological features of adult form nemaline myopathy. Methods Biopsied muscle specimens from two patients were observed using enzymatic histochemical method and electron microscope. Results These two patients were found with an initial onset from neck muscle weakness at the age of 52 and 36 years respectively, followed by trunk and limb muscle involvement to a variant degree. Type Ⅰ fiber atrophy and numerous granules (rod) were found in both patients in light microscopy. In case 1, the centralized nuclei were seen almost in all normal sized muscle fibers. Electron microscopic observation showed marked myofibril disorganization and numerous rod-like formations. Two inclusion-carrying nuclei were detected in case 1. The intranuclear inclusion showed a lattice pattern of Z-disc line or sarcoplasmic rod. Conclusions Adult form nemaline myopathy is clinically nonspecific. Rod-like structures might be found either in sarcoplasma or in nucleus. Centralized nuclei might coexist with rods in adult form nemaline myopathy. As compared to the child form, the adult one might often show a marked muscle fiber atrophy.
