Objective: To analyze the relationship between high-sensitivity C-reactive protein (hs-CRP) and P wave dispersion (Pd) in patients with lone atrial ifbrillation (AF), and to explore the effect of inlfammation on atrial electrophysiological remodeling.
Methods: Our research included 2 groups. AF group, containing 71 consecutive paroxysmal lone AF patients, and Control group, containing 71 paroxysmal supra ventricular tachycardia patients with the matched age and gender. The clinical characteristics, electrocardiographic Pd assessment and plasma hs-CRP levels were compared between 2 groups. The relationship between hs-CRP and Pd was studied by linear and multi linear regression analysis.
Results: Compared with Control group, AF group showed increased left atrial diameter, Pd and hs-CRP, all P<0.05. multilinear regression analysis indicated that hs-CRP was positively related to Pd in both groups, P<0.01. Multiple logistic regression analysis revealed that hs-CRP was an independent risk factor for AF occurrence (HR=15.430, 95%CI 6.031-39.476, P<0.001), with adjusted Pd, multiple logistic regression analysis presented that both Pd and hs-CRP were the independent risk factors for AF occurrence, both P<0.001, while the HR for hs-CRP predicting AF occurrence was attenuated from 15.430 to 6.246.
Conclusion: Plasma hs-CRP level and electrocardiographic Pd were the important risk factors for paroxysmal lone AF, the interaction between hs-CRP and AF occurrence could be mediated by Pd, suggesting that inlfammation might be involved in atrial electrophysiological remodeling.

Objective: To study the safety and efifcacy of hematoma aspiration with manual compression for treating the patients of femoral pseudoaneurysm after cardiac catheterization under ultrasound guidance. Methods: A total of 27 patients suffering from post-catheterization iatrogenic femoral pseudoaneurysm were analyzed including 14 male and 13 female at the mean age of (53.5±11.4) years. The body, neck and blood supply area of pseudoaneurysm were located by ultrasonography; 18 gauge needle was punctured into the center of pseudoaneurysm to aspirate blood, meanwhile the neck and body of pseudoaneurysm were manually compressed to block blood supply for relevant artery under ultrasound guidance. Manual compression was conducted for 15 min followed by bandage compression; the patients were lie on the back and kept lower extremity straight for 12 hours. Ultrasonography was performed at 24 hours and 1 month after the operation in all patients respectively. Results: There were 24/27 (88.9%) patients having successful aspiration with manual compression at ifrst time; 2 (7.4%) having incomplete occlusion at ifrst time and the success was obtained by second time; 1 having incomplete occlusion due to coexisted femoral arteriovenous ifstula, while the body of pseudoaneurysm was obviously decreased. The overall success rate was 96.3% (26/27), no procedural complication occurred. Conclusion Ultrasonography guided hematoma aspiration with manual compression has been safe and effective for treating the patients of iatrogenic femoral pseudoaneurysm.

Objective To explore the clinical effect of psychological rehabilitation on dysphagia with cognitive and psychological disorders post stroke. Methods 120 stroke patients with dysphagia complicated with cognitive and psychological disorders were divided into experimental group (n=60) and control group (n=60). Both groups received neurological routine medical treatment, swallowing function rehabilitation training, feeding training and low-frequency electrical stimulation. Cognitive and psychological therapy was additionally used in the experimental group. Both groups were assessed by Kubota DrinkingWater Test, Mini-Mental State Examination (MMSE), Hamilton Rating Scale for Depression (HAMD) and Hamilton Rating Scale for Anxiety (HAMA). Results 1 month after intervention, the score of Kubota Drinking Water Test improved significantly in both groups, and was higher in the experimental group than in the control group (P<0.001).The rate of clinical improvement was higher in the experimental group than in the control group (P<0.01). The scores of MMSE increased significantly in the experimental group (P<0.001). The scores of HAMD and HAMA decreased significantly in the experimental group (P<0.01). Only the scores of HAMA decreased in the control group (P<0.05). Conclusion Swallowing function rehabilitation training combined with cognitive and psychological therapy may facilitate to improve the cognitive function and psychological state and swallowing function for dysphagia with cognitive and psychological disorders post stroke.

Purpose To ana1yze the expression features of 5-F1uorouraci1(5-FU)metabo1ic enzyme thymidy1ate synthetase(TS),thy-midine phosphory1ase( TP),dihydropyrimidine dehydrogenase( DPD)and its re1ationship with c1inicopatho1ogica1 factors and progno-sis in co1orecta1 cancer,in order to further exp1ore its potentia1 significance in guiding co1orecta1 cancer chemotherapy. Methods Es-tab1ishment of a tissue microarray containing 72 patients with co1orecta1 cancer,and 56 norma1 tissue( dista1 cut edge tissue near carci-noma)was used to detect TS,TP,and DPD by immunohistochemistry,and to ana1yze its re1ationship with c1inicopatho1ogica1 factors and prognosis of co1orecta1 cancer through statistica1 method. Results The expression of TS in co1orecta1 cancer was 1ower than that in norma1 tissue(P=0. 876),which was associated with TNM(P=0. 043)and positive1y corre1ated with patients’overa11 surviva1(P=0. 027),the expression of TP in co1orecta1 cancer was higher than that in norma1 tissue(P=0. 315)that was associated with 1ymph node metastasis(P=0. 009)and negative1y corre1ated with the prognosis of patients(P=0. 040),DPD expression in co1orecta1 canc-er was higher than that in norma1 tissue(P=0. 071),which was re1ated to the histo1ogic type(P=0. 029). Overa11 surviva1 was sig-nificant1y shortened in co1orecta1 cancer with DPD high expression( P=0. 011). Conclusions TS,TP and DPD might be app1ied as important index of prognosis in co1orecta1 cancer patients using 5-FU adjuvant chemotherapy. The expression of TS re1ated c1ose1y with the c1inica1 stage is a bio1ogica1 marker of tumor progression. TP expression is c1ose1y re1ated to 1ymph nodes metastasis and recur-rence,which is an important factor of postoperative recurrence and metastasis.

Objective To investigate the toxicity of alpha terthienyl to the larvae of Aedes albopictus , its influencing factors and effect on the larva deve lopment. Methods Under experimental ultraviolet A (UVA),the number of dead,pupal or eclosive mosquito larvae was determined on the condition of different doses of alpha terthienyl and different disposal time in the dark;the number of dead larvae was also determined under sunlight on the condition of different doses of alpha terthienyl and different disposal time to water. Results The LC 50 of alpha terthienyl to Aedes albopictus larvae was 2.37 ?g/L under UVA. The best effect was shown when the larvae were incubated with alpha terthienyl 3 h in dark. Alpha terthienyl could significantly inhibit the larva deve lopment and the emergence of the pupae. Under strong sunlight, the larvae were quickly killed by high concentration alpha terthienyl. The 24 hours effect of alpha terthienyl was better when it was applied at 5 AM than that of at 10 AM and 1PM. Conclusion Alpha terthienyl is an effective, practicable larvicide which prohibits the growth and development of the larvae of Aedes albopictus .

Background One of the major challenges in arrhythmogenic right ventricular cardiomyopathy (ARVC) ablation is ventricular tachy-cardia (VT) non-inducibility. The study aimed to assess whether fast rate (≥ 250 beats/min) right ventricular burst stimulation was useful for VT induction in patients with ARVC.Methods Ninety-one consecutive ARVC patients with clinical sustained VT that underwent electro-physiological study were enrolled. The stimulation protocol was implemented at both right ventricular apex and outflow tract as follows: Step A, up to double extra-stimuli; Step B, incremental stimulation with low rate (< 250 beats/min); Step C, burst stimulation with fast rate (≥ 250 beats/min); Step D, repeated all steps above with intravenous infusion of isoproterenol.Results A total of 76 patients had inducible VT (83.5%), among which 49 were induced by Step C, 15 were induced by Step B, 8 and 4 by Step A and D, respectively. Clinical VTs were induced in 60 patients (65.9%). Only two spontaneously ceased ventricular fibrillations were induced by Step C. Multivariate analysis showed that a narrower baseline QRS duration under sinus rhythm was independently associated with VT non-inducibility (OR: 1.1; 95% CI: 1.0–1.1;P = 0.019).ConclusionFast rate (≥ 250 beats/min) right ventricular burst stimulation provides a useful supplemental method for VT induction in ARVC patients.

OBJECTIVE:To explore the effects of early treatment with mouse nerve growth factor on the wound healing in aged patients with electric burn. METHODS:78 elderly patients with electric burn were divided into control group and observation group by random number table method,with 39 cases in each group. Control group was given routine method for electric burn, and observation group was additionally given Mouse nerve growth factor for injection 30 μg dissolved in 2 ml 0.9% Sodium chlo-ride injection within 24 h,im,qd,on the basis of control group. Treatment course of 2 groups lasted for 2 weeks. Clinical effica-cies of 2 groups were compared as well as VAS score before treatment,3,5,7 days after treatment. The survival rate of skin flaps and the rate of wound healing 3,5,7 days after treatment,the recovery of wound scar,the value of wound blood perfusion,the time of complete wound healing and the occurrence of ADR were also compared. RESULTS:The total effective rate of observation group(94.9%)was significantly higher than that of control group(66.7%),with statistical significance(P<0.05). 3,5,7 days after treatment,VAS score of observation group was significantly lower than that of control group,and the survival rate of skin flaps and the rate of wound healing were significantly higher than those of control group,with statistical significance(P<0.05). Af-ter treatment,VSS score of observation group was significantly lower than that of control group,while the value of wound blood perfusion was significantly higher than that of control group;the time of complete wound healing was significantly lower than that of control group,with statistical significance (P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Early treat-ment with mouse nerve growth factor for elderly patients with electric burns can effectively lower the VAS and VSS score,improve the survival rate of skin flaps and the rate of wound healing,increase the value of wound blood perfusion and shorten the time of complete wound healing with good clinical efficacy and safety.
