Objective To observe the serum levels of homocysteine (Hcy) and hypersensitivity C-reactive protein(hs-CRP) in elderly patients with cerebral infarction and to investigate their relationship and clinical significance by National Institutes of Health Stroke Scale (NIHSS).Methods The serum levels of Hcy and hs-CRP were by enzymatic cycling method and scattering turbidimetry in the elderly patients ( 116 cases with cerebral infarction and 100 cases of healthy control).Those 116 cases with cerebral infarction were divided into three groups by the degree of NIHSS.The three groups were compared with each other.Results The levels of serum Hcy and hs-CRP in elderly patients with cerebral infarction were significantly higher than that of healthy control group ( t =6.97,P ＜0.01 ; t =14.96,P ＜0.01 ).There has significant difference among those three groups with cerebral infarction by comparing with each other( F =23.49,P ＜0.05; F =28.19,P ＜0.05).A positive correlation was found between Hcy and degree of NIHSS( r=0.54,P ＜0.05),and between hs-CRPand degree of NIHSS( r =0.58,P ＜0.05).Conclusions Serum levels of Hcy and hs-CRP are correlated with the occurrence of cerebral infarction and its severity.There has positive clinical significance to evaluate the effect of cerebral infarction by measuring the serum levels of Hcy and hs-CRP dynamic.

Objective:To explore the incidenee of early hematoma growth in patients with intracerebral hemorrhage,and the correlation between early hematoma growth and early neurological deterioration.Methods:The evaluation of nervous system and CT scan in patients with intracerebral hemorrhage within 3 hours after the omet of symptoms were performed respectively at baseline,and 1,2,3,and 20 hours after the baseline.Results:In 106 patients,CT scan shelwed that the volume of intraparenehymal hemorrhage inereased significantly in 26% of patients at baseline and within 1 hour.CT scan showed that the bleeding volume increased in 12% of patients at 1,2,3,and 20 hours.By measuring baseline,1-hour Glasgow Coma Scale (GCS)score,and the changes of the National Institutes of Health Stroke Scale(NIHSS),it had found that the baseline status and the increased bleeding volume within 1 hour vdgre closely correlated with the clinical neurological deterioration.Conclusions:The early bleeding volume often inereases significantly in patiems with intracerebral hemorrhage,which is complicated with neurological deterioration.In order to determine whether these therapeutic measures improve the natural course of this early hematoma growth and decrease its occurrence,it is necessary to make a randomized clinical trial.

Objective To explore the impact of hyperglycemia on Hypersensitive C-reaction protein (hsCRP),B-type natriuretic peptide(BNP) and ventricular remodeling in elder patients with acute myocardial infarction(AMI).Methods One hundred and twenty elder patients with AMI are divided into hyperglycemia group(blood sugar in admission ＞ 7.8 mmol/L) and non-glycemia group(blood sugar in admission ≤7.8 mmol/L).The levels of blood sugar in admission,hsCRP,BNP were detected.LVEF,LVEDD,LVESD,WMS were observed by cardiac echo in admission and two weeks after therapy.Results The blood sugar in admission,hsCRP and BNP of the patients in hyperglycemia group were (9.6 ± 0.6) mmol/L,(1 750.6 ±677.1) ng/L,(56.1 ±38.6) ng/L,higher than those in non-glycemia group (t =38.679 and P =0.000; t =11.941 and P =0.000; t =3.288 and P ＜0.01,respectively).LVEF,LVEDD,LVESD and WMS of patients in hyperglycemia group didn't show statistical significance before and after therapy.However,there were significant in hyperglycemia group (t =2.049 and P =0.043,t =2.836 and P =0.005,t =3.814 and P =0.000,t =2.086 and P =0.039,respectively).Conclusion Hyperglycemia can reduce the increase of hsCRP and BNP,which has an impact on hsCRP,BNP and ventricular remodeling in elder patients with acute myocardial infarction,but the mechanism need to further research.

Objectives To analyze the expression of fibroblast growth factor-19(FGF-19) in hepatocellular carcinoma ( HCC) and adjacent tissues , and to investigate its clinical significance .Methods A total of 209 HCC patients who had undergone radical resection operations at Hospital 401 between January 2003 and December 2009 were chosen as samples . Immunohistochemistry method was employed to examine the expression level of FGF-19 in HCC and adjacent tissues .The relationship between FGF-19 protein expressions and clinicopathological features was analyzed by the chi -square test or Fisher exact probability .A survival curve was drawn using the Kaplan-Meier method and the Cox model was used to analyze factors that influenced survival .Results The rate of high expression of FGF-19 was 66.1% (138/209) in HCC, which was significantly higher than 46.9%(98/209) in adjacent tissues (P<0.05).The high expression of FGF-19 was related to the tumor capsule and tumor boundary (P<0.05).The overall survival in high expression of FGF-19 group was signifi-cantly lower than that in low expression group (P<0.05).Conclusion FGF-19 plays an important role in the carcinogen-esis and development of HCC , and a high expression of FGF-19 might be closely related to survival time of postoperative patients.FGF-19 might be a potential prognosis prediction factor for HCC .

For unresectable advanced hepatocellular carcinoma (HCC),besides sorafenib,alternative drugs and treatment modalities are required.Clinical studies of hepatic arterial infusion chemotherapy (HAIC),transcatheter arterial chemoembolization (TACE),and system chemotherapy have shown favorable efficacy and tolerance in advanced HCC patients.In addition,the potential efficacy of sorafenib combined with focal treatment is also an interesting issue.As more therapies become available,decision-making for treating advanced HCC becomes increasingly complex.In our opinion,diverse treatment modalities should be utilized for the best interest of patients.Based on predictive biomarkers,we should develop a precise patient stratification system to select suitable candidates for each treatment modality in future studies,as is useful for improving prognosis of patients with advanced HCC.

Objective To explore the diagnosis,treatment,risk factors and prognosis factors of postpancreaticoduodenectomy hemorrhage (PPH).Methods The retrospective case-control study was adopted.The clinical data of 703 patients who underwent pancreatoduodenectomy at Hospital 401 of the People's Liberation Army from January 2008 to July 2013 were collected.Standard pancreatoduodenectomy was carried out for the malignant tumors of the head of pancreas or ampulla,pylorus-preserving pancreatoduodenectomy was operated for the benign tumor or the duodenal papilla tumor.The corresponding treatment was adopted for PPH.The observation indicators included:(1) the surgical situation (surgical method,operation time and the volume of intraoperative blood loss),(2) diagnosis of PPH,(3) treatment of PPH,(4) univariate and multivariate analyses for the risk factors affecting the occurrence of PPH,(5) univariate and multivariate analyses for the risk factors affecting prognosis of PPH patients.The measurement data with normal distribution were represented as x ± s.The measurement data with skewed distribution were represented as M (range).The chi-square test or Fisher exact probability was used for univariate analysis.Logistic regression model was used for multivariate analysis.Results (1) The surgical situation:among 703 patients,409 patients underwent standard pancreatoduodenectomy and 294 underwent pylorus-preserving pancreatoduodenectomy,including 1 combined with right hemihepatectomy,27 with portal vein reconstruction and 2 with hepatic artery reconstruction.Pancreaticojejunostomy was applied to 658 patients using mucosa anastomosis of the pancreatic duct to jejunum and 45 patients using invagination anastomosis.Supporting tube was routinely deposed in the pancreatic duct,598 patients had internal drainage and 105 patients had external drainage.The end-to-side anastomosis between common bile duct and jejunum was used for choledochojejunostomy.The 409 patients received the gastrojejunostomy using side-to-side anastomosis of gastric part and jejunum and 294 patients using end-to-side anastomosis of duodenum and jejunum.Operation time and volume of intraoperative blood loss were (324 ± 54) minutes and (428 ± 118) mL.(2) The diagnosis of PPH:among 703 patients after pancreatoduodenectomy,62 patients had PPH,the hemorrhage reasons of 38 patients had been identified,and the hemorrhage reasons of 24 patients had not been identified (A level in 5 patients,B level in 17 patients,C level in 2 patients).① The site of hemorrhage:the hemorrhage outside the cavity were detect in 27 patients,the hemorrhage inside the cavity in 28 patients,and the hemorrhage from both outside and inside part of the cavity in 7 patients.② The time of hemorrhage:early-stage hemorrhage were detected in 5 patients and the delayed hemorrhage in 57 patients.③The volume of postoperative blood loss was (885 ± 253)mL,30 patients had mild hemorrhage and 32 patients had severe hemorrhage.④ The clinical classification of PPH:5,32 and 25 patients were detected in level A,B,C,and 19 patients combined with sentinel hemorrhage.(3) The treatment of PPH:①5 patients with PPH in A level were given clinical observation,blood volume supplement and other treatment,then the symptoms gradually turned better.② Among 32 patients with PPH in B level,15 patients became better after symptomatic and supportive treatments,6 patients received successful hemostasis after guglielmi detachable colis embolization,4 patients received successful hemostasis under gastroscopic hemostasis,7 patients received emergency exploratory laparotomy.Thirty-two patients were improved and then out of hospital after treatment,without occurrence of death.③ Among 25 patients with PPH in C level,4 patients received successful hemostasis after guglielmi detachable colis embolization,17 patients received hemostasis by emergency exploratory laparotomy,4 patients with undiscovered bleeding points received the treatment of fluid infusion,blood volume supplement and antacid.Among 25 patients after corresponding treatment,10 patients were improved and 15 patients were dead.(4) The result of univariate analysis showed that the combined hypertension,vascular resection and reconstruction,postoperative pancreatic leakage and postoperative intraabdominal infection were risk factors affecting the occurrence of PPH (x2 =4.950,5.300,7.568,5.505,P ＜ 0.05).The results of multivariate analysis showed that the combined pancreatic leakage and postoperative intraabdominal infection were independent risk factors affecting the occurrence of PPH [OR =2.761,2.216,95％ confidence interval (CI):1.389-5.489,1.198-4.101,P ＜ 0.05].(5) The risk factors affecting the prognosis of PPH patients:the results of univariate analysis showed that postoperative sentinel hemorrhage,postoperative pancreatic leakage,site,degree and level of hemorrhage were risk factors affecting the prognosis of PPH patients (x2 =8.022,4.448,11.853,18.551,28.285,P ＜ 0.05).The results of multivariate analysis showed that postoperative sentinel hemorrhage and site of hemorrhage (outside and inside part of the cavity) were independent risk factors affecting the prognosis of PPH patients (OR =5.550,0.233,95％ CI:1.595-19.314,0.086-0.635,P ＜ 0.05).Conclusions Pancreatic leakage and intraabdominal infection are independent risk factors after pancreatoduodenectomy.The treatment effect of the early-stage hemorrhage is better than that of the delayed hemorrhage,and angiographic embolization is the first choice of diagnosis and treatment for the delayed hemorrhage.Sentinel hemorrhage could result from aneurysm or continuous arterial hemorrhage of vascular erosion,it is the independent risk factor affecting the death of hemorrhage after pancreatoduodenectomy.

Objective To reduce the rate of dysphagia and inhalation pneumonia by changing the food dense and evaluate the swallow function by videofluoroscopy(VF) and fiberoptic endoscopic examination of swallowing(FEES). Methods The videofluoroscopy and fiberoptic endoscopic examination of swallowing were used in 50 healthy volunteer and 35 dysphagia person. Results Aspiration was find in 14% volunteer and penetration was find in 36% volunteer. The positive rate of videofluoroscopy was higher than of fiberoptic endoscopic examination of swallowing in the two indicators. The delay of the thin barium passed the pharynx was the danger factor of aspiration. Videofluoroscopy was more sensitive in diagnosis of penetration. The time that watery barium and pudding barium flowed from pharynx to epiqlottis is longer in patients than that in volunteer. Conclusion The videofluoroscopy and fiberoptic endoscopic examination could be predicted to some extend by some clinical swallowing abnormalities, which could increase the accuracy of clinical evaluation . The viscosity changing can decrease the rate of dysphagia and inhalation pneumonia.

Objective To explore the effect of aldosterone on renal epithelialmesenchymal transition in streptozocin(STZ)-induced diabetic nephropathy rats. Methods Wistar rats were intraperitoneally injected with STZ(60 mg/kg)for the preparation of diabetic model.After 4 weeks,the rats with urinary protein＞30 mg/d were regarded as successful diabetic nephropathy(n=16),and were randomly divided into diabetic nephropathy(DN group,n=8)and spironolactone group(SP group,n=8).Then eight healthy rats were selected randomly as control group(N group,n=8).SP group rats were treated with spironolactone 40 mg·kg-1·d-1,and N group and DN group rats were given equal water.After 8 weeks,rats were sacrificed to collect urine,blood plasma,kidney tissue for detection of 24 h urinary protein,creatinine and renal pathological changes.Aldosterone concentration in plasma and kidney tissue was detected by mdioimmunoassay;E-cadherin,α-SMA protein expression by immunohistochemistry,Western blotting; E-cadherin,α-SMA mRNA expression by RT-PCR. Results Compared with N group,serum creatinine, urinary protein excretion in the DN rats were significantly higher (P＜0.01,respectively), E-cadhefin protein and mRNA were significantly reduced (P＜0.01, respectively),α-SMA protein and mRNA expression was up-regulated (P＜0.01, respectively). Aldosterone level of kidney tissue in DN rats was increased obviously [(24.71±5.30) ng/g vs (16.38±2.85) ng/g, P＜0.01], which was positively correlated with urinary protein excretion, serum creatinine and α-SMA protein (r=0.737, 0.574, 0.688, P＜0.01, respectively), and negatively correlated with E-cadherin protein (r=-0.659, P＜0.O1). While no significant difference was found in serum aldosterone among three groups. Compared with DN rats, urinary protein excretion, serum creatinine were reduced (P＜0.01, respectively), E-cadherin protein and mRNA were increased (P＜0.01, respectively), α-SMA protein and mRNA expression were decreased (P ＜0.01, respectively) in SP group rats.Conclusions Local aldosterone involves in renal epithelial-mesenchymal transition in diabetic nephropathy rat. Spironolactone can block the effect of aldosterone and play a role in renal protection.

Objective To observe the correlation between P-selectin and troponin-T in aged people.Meth-ods P-selectin and troponin-T were detected in 80 patients,who were divided into two groups according to the level of troponin-T:group A(normal level of tropenin-T)and group B (abnormal level of troponin-T).The relationship of P-selectin and tropenin-T were compared in the two groups.Results P-selectin in group B was increased remark-ably than that in group A(P<0.01).P-selectin had positive correlation with tropenin-T by single factor analysis(r=0.824.P<0.01).Conclusion Cardiac sensitivity and specificity of P-selectin is lower than that of troponin-T,but both P-selectin and troponin-T offer simple and convenient methods of indirect judgment of the degree and prog-nosis of coronary artery disease and myocardial damage.

Objective To determine the relationship between the level of plasma homocysteine and coronary calcification in patients with different blood glucose levels. Methods By measuring plasma homocysteine and coronary calcification in 30 cases of diagnosed diabetes (T2D) ,29 cases of diagnosed impaired glucose tolerance (IGT) in patients and 27 cases with normal, we compared the level of plasma homocysteine and coronary calcification in patients with different blood glucose levels. Results We found significant diffieronces among three groups of the level of plasms homocysteine and coronary calcification (P ＜ 0.01). The plasma homocysteine levels were(19.31 ±3.17) μmol/L, (13.85 ± 1.62) μmol/L, (9.80 ± 1.78) μmol/L in the T2D,IGT and normal groups,respectively. The coronary calcification scores were 207.80 ± 154.10,63.24 ± 10.46,14.47 ± 5.16 in the T2D, IGT and normal groups, respectively. The plasma homocysteine level and coronary calcification score increased with the glycosylated hemoglobin rise in the normal,IGT and T2D groups((4.51 ±0.48)%, (6.13 ±0.31)% and (7.69 ±0.81)%, respectively). Conclusions The plasma homocysteine level is a strong independent predictor of type 2 diabetes and also an important factor of coronary artery event occurrence and develepment.
