Objective To investigate the influence of co-expression state of p14 ARF and p16 INK4a protein on radiochemotherapy and length of survival period in patients with non-small cell lung cancer(NSCLC)after resection. Methods Thirty-five patients with negative p14 ARF and p16 INK4a co-expression and 20 patients with positive p14 ARF and p16 INK4a co-expression were enrolled for the study. The co-expression of the said proteins were previously determined by immunohistochemistry (S-P). Clinical pathological characteristics were compared between two groups, and the survival time and the results of radiochemotherapy of patients were respectively recorded and analysed. Results No significant differences were found in age, TNM stages, degree of differentiation, recurrence/metastasis and radiochemotherapy between two groups. However, there was significant differences in sex, smoking index, and pathological classification. It was found that 2-year, 3-year and total survival rate were significantly lower in patients with p14 ARF and p16 INK4a co-expression than those with positive co-expression (P

Objective To summarize our experience in management of infected femoral artery pseudoaneurysm caused by addictive drugs injection.Methods Clinical data of 45 cases of infeted femoral artery pseudoaneursysm were reviewed retrospectively.When infected femoral artery pseudoaneurysm was diagnosed,the femoral artery or external iliac artery was ligated and the pseudoaneurysm was resected in all of cases.Anticoagulants and antibiotics were used after operation.Results Lower limbs were salvaged in 44 patients.The ambulation function of affected limb was fine in the short-term.One limb was amputated because of lower limb deep venous thrombosis and gangrene.Thirty-four patients(75.6%) were followed up for 3-12 months,the results were satisfactory.Conclusions Femoral artery or external iliac artery ligation is an effective procedure for management of infected femoral artery pseudoaneurysm.

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 study the curative effect of percutaneous radiofrequency ablation (PRFA) on liver tumors. Methods A total of 66 patients underwent PRFA under ultrasound guidance for the total frequencies of 146. AFP, B-US, and CT examinations were conducted before and after the operation. A follow-up for 6 months was carried out. Results PRFA was successfully performed on all patients. Serious complications and death were found in 2 cases. The follow-up revealed complete disappearance of tumor masses in 6 cases. The diameter of tumor reduced by 1/2 were found in 24 cases, and

Objective To evaluate the methods,applicability and results of cndovascular therapy for Stanford type B aortic dissection.Methods The clinical data of 36 cases of Stanford type B aortic dissection were analysed retrospectively.The stent-grafts were introduced via femoral arteriotomy.Stent-grafts were implanted to blockade tears of aortic dissection under the guidance of DSA.Results In all cases,the aortic dissection tears were blockaded,true lumens were opened,and organs function was restored.There were not complications such as internal hemorrhage due to trauma or stent displacement on CTA 3 and 12 months after endovascular therapywhile 2 cases developed new tears.The caliber of the 36 true lumens was restored to near normal.Twenty-two pseudocoeloms were obliterated,while the others were reduced is size and had varying degrees of thrombosis.Conclusions Endovascular thcrapy is safe and effectivc for the patients with Stanford type B aortic dissection.Its clinical application has a favorable outlook.

Objective To observe the relationship between urine albumin excretion rate (UAE), growth factors and the bone mineral density (BMD) in elderly patients with type 2 diabetes mellitus. Methods Fourteen controls and 51 elderly male patients with diabetes divided into three groups: normal albuminuria(UAE

Ca2+ leak via ryanodine receptor type 2 (RyR2) can cause potentially fatal arrhythmias, and RyR2 mutations have been shown in the aetiology of catecholaminergic polymorphic ventricular tachycardia. We report the case of a patient with catecholaminergic polymorphic ventricular tachycardia resulting from a RYR2 mutation who had not only typical electroencephalogram changes, but also epileptiform discharges in electroencephalogram. We believe the changes were closely related to the RYR2 mutation.

Objective: To study quantitative changes of cochlear hair cells and spiral ganglion cells after blast exposure in guinea pigs. Methods: The number of hair cells was calculated using the surface specimen technique and computer image analysis technique after blast exposure. The number of spiral ganglion cells was calculated using pathologic technique and computer image analysis technique after blast exposure. Results: Quantitative observation was carried out 21 days after blast exposure. The number of total hair cells in uncus, the first and second gyre in normal control group and in blast group was 3 599?159.6 and 6 022?98.4 respectively, and the number of spiral ganglion cells in the 2 low parts of cochlear in normal control group and in blast group was 51? 4.72 and 27? 6.94 respectively, the difference in mean value between the groups being significant. Conclusion: Not only the hair cells reduce, but also the spiral ganglion cells are severely damaged after blast exposure. [

Objective To study the relationships of hemoglobin(Hb)level with the levels of neurohormones,and cytokines,and the effect of them on ventricular remodeling in patients with congestive heart failure(CHF). Methods Hb level,serum angiotensinⅡ(Ang Ⅱ ),tumor necrosis factor-α(TNF-α),nitric oxide(NO),soluble intereellular adhesion molecule-1(sICAM-1)and B-type natriuretic peptide(BNP)were measured in 121 CHF patients.The left ventrieular ejection fraction (LVEF)from echocardiography,left ventricular mass index(LVMI),and mean wall stress(MWS)were calculated. Results The levels of Ang Ⅱ,TNF-α,NO,siCAM-1,BNP[(144.5±64.1)ng/L,(92.3±6.4)ng/L,(65.2±4.2)μmol/L,(253.6±26.0)μg/L,(1294.0±223.0)ng/L]and LVMI,MWS in the anemia group of CHF patients were higher than those in the non-anemia group[(76.7±48.5)ng/L,(55.6±10.2)ng/L,(42.1±11.9)μmol/L,(237.18±33.26)μg/L,(437.0±115.0)ng/L,all P＜0.01].With the increase of anemia severity,the levels of AngⅡ,TNF-α,NO,siCAM-1,BNP and LVMI,MWS were significantly increased.There were negative correlations between Hb level and the 1evels of AngⅡ,TNF-α,NO,siCAM-1,BNP,LVMI,MWS(r=-0.8173,-0.8509,-0.6001,-0.6692,-0.6283,-0.8604,-0.8733,all P＜0.01),and negative correlations between LVMI,MWS and Hb levels and LVEF(P＜0.01). Conclusions Neurohormones and cytokines play roles in ventrieular remodeling and anemia in CHF aggravates the severity of ventricular remodeling.

OBJECTIVETo compare the clinical effect of the double eyelid blepharoplasty with central minimal incision and with three minimal incisions. Methods: From Jul. 2010 to May 2012, 268 cases (Group A) received double eyelid blepharoplasty with central minimal incision, while 102 cases (Group B) underwent double eyelid blepharoplasty with three minimal incisions. Photos were taken immediately, and 1,2, 4, 8,12 weeks after operation. Operation time, recovery time and postoperative complications were evaluated and recorded. The operation time and recovery time were analyzed by Wilcoxon rank sum test. The postoperative complications were analyzed by chi square test. The satisfactory degree was analyzed by t test.

RESULTSThe operation time in Group A was (25.63 ± 3.74) min, compared with that (29.90 ± 4.13) min in Group B (Z = -8.011, P <0.01). Meanwhile, the recovery time in Group A was shorter than that in Group B (Z = -15.887, P <0.01). The occurrence rate of postoperative complications,including hematoma,recurrence and scar hyperplasia in Group A was also lower than that in Group B. At the same time, the satisfactory degree in Group A was(97.302 ± 1.764), which was higher than that(88.628 10.880) in Group B (t = 12.650, P <0.05).

CONCLUSIONSThe double eyelid blepharoplasty with central minimal incision, which is suitable for all cases except those who has serious blepharochalsais, has more advantages than double eyelid blepharoplasty with three minimal incisions.
