Objective Accelerated junctional rhythm (AJR) always occur during slow pathway catheter ablation for atrioventricular nodal reentrant tachycardia (AVNRT), the clinical significance of it has not been gotten in agreement. The aim of this study is to search for an association between AJR and ablation target site or tachycardia recurrence.Methods The data of 247 patients with AVNRT who received radiofrequency ablation procedure during April 1995 to October 1999 was analyzed. All these people were divided into two groups (212 patients in the successful ablation group or group 1, 35 patients in the recurrence group or group 2). The AJR was divided into two distinct pattern:type Ⅰ(continuous AJR that persisted until the end of energy delivery) and type Ⅱ (intermit AJR alternated with sinus rhythm during slow pathway ablation, which was eliminated immediately when stopping energy delivery ). Results\ The results showed that patients in group 1 exhibited better AJR response, most of them were seen with type Ⅱ AJR. However most of the people in group 2 had no AJR response throughout energy delivery , few of them had type Ⅰ AJR response. The AJR response of group 1 started relatively earlier than that of group 2(3 2?1 8 vs 5 7?2 5 ,P

In the research field of quality control in Chinese medicinal materials, variation in active ingredients of medicinal plant is always the key and hot issues. With the development of high-throughput sequencing technologies and reducing cost, a large numbers of genes from medicinal plant were cloning and provide a solid foundation for further research of gene structure and its biological function, and also provides conditions for explore active ingredient variation and its quality control from the perspective of molecular pharmacognosy. This paper introduces the concept of homologous gene, gene duplication and classification. We prospect the function of duplicated genes in the role of molecular mechanism research about variation in active ingredients, aiming at providing a new way for medicinal materials quality control.

Objective To investigate the relationship between expression of nuclear factor kappa B p65 ( NF-κB p65) and hippocampal neuronal apoptosis in acute necrotizing pancreatitis (ANP) rats with brain injury. Methods Sixty-four SD rats were randomized into normal saline group (NS) and ANP group. The ANP rat model was induced by retrograde injection of 4% sodium taurocholate into the pancreaticobiliary duct of SD rats. Nissle stain was used to detect the brain injury. Neuronal apoptosis was determined by TUNEL.NF-κB p65 expression was detected by immunohistochemistry and RT-PCR. Results Hippocampal neuron was absent, karyopyknosis, unclear nucleolus and decreased Nissl bodies were found, the injuries was aggravated with time. The apoptosis index at the 3, 6 and 12 h in ANP group was 10.63 ±0.24, 21.02±0.25, 17.12±0.36, respectively, while they were 0.33±0.19,0.71±0.67, 0.45 ± 0. 33 in NS group, and the difference was statistically significant ( P < 0. 01 ). The expressions of NF-κB p65 mRNA were 0. 63 ± 0.05,1.05 ±0.06,0.92 ±0.05, which were significantly higher than those in the NS group (0.11 ±0.01,0.12±0.01,0.08±0.01,P<0.05).The chatge of expression of NF±κB p65 protein was consistent with that of NF-κB p65 mRNA. Conclusions The brain injury of ANP rats was highly correlated with neuronal apoptosis at the early and middle phase of ANP, and its mechanism may be related with NF-κB p65 activation.

Objective To investigate the effects of cystectasia with sodium hyaluronate solution on ketamine related cystitis.Methods From June 2008 to October 2012,29 patients with ketamine related cystitis were analyzed,among which 27 were males and 2 were females.Their age ranged from 18 to 36 years old with a mean age of 25.All of them had frequency,urgency,urodynia and suprapubic pain.Voiding volume ranged from 10 to 160 ml and the interval duration ranged from 10 to 60 min.The test of ketamine in urine was positive.Patients were divided into four groups according to the treatment modality,namely the surgical treatment group (group A,n =11),surgery followed by addiction relapse group (group B,n =7),drug treatment group (group C,n =6) and non-drug treatment group (group D,n =5).Patients in group A and B underwent cystectasia with sodium hyaluronate solution under combined spinal-epidural anesthesia,and patients in group B were reported of addiction relapse within 2 weeks after cystectasia treatment.Patients in group C were free of the addiction to ketamine,while those in group D still rely on the ketamine.The average urine volume,OABSS and PUF scores were recorded 2 weeks and 4 weeks after the treatment.Results Two weeks after cystectasia,the average urine volums in group A and B were (107.7±39.6) ml and (95.0±35.5) ml respectively,which was larger than that in group D (42.0±13.5) ml,plus the volume in group A was larger than that in group C (63.3± 16.3) ml.The aforementioned differences were considered statistically significant (P<0.05).As for OABSS and PUF scores,scores in group A [(6.0±2.6),(14.8± 4.2)] were lower than those in group C [(9.5±2.4),(22.5±2.2)].Furthermore,scores in group B [(9.0±2.4),(19.57±2.7)] were lower than those in group D [(12.2±1.9),(26.4±3.5)] (P<0.05).Four weeks later,the average urine volume,OABSS and PUF scores in group A [(106.4±37.5) ml,(5.6± 2.5),(13.5±4.0)] and group C[(113.3±27.3) ml,(6.3±2.2),(14.5±2.7)] were significantly different from those in group B [(52.1±21.6) ml,(11.1±1.3),(26.4±2.8)] and group D [(40.0±13.7)ml,(12.0±1.6),(26.6±3.6)] (P<0.05).While,no obvious distinction was observed between group A and group C,group B and group D in terms of average urine volume,OABSS and PUF scores at 4 weeks postoperatively (P>0.05).Conclusions Cystectasia can efficiently alleviate lower urinary tract syndromes in patients with ketamine related cystitis.

Objective To explore the characteristics of sleep disturbance and its related factors in patients with rheumatoid arthritis (RA).Methods A total of 71 patients with RA in Department of Rheumatology Huaxi Hospital have completed the following questionnaires, including Pittsburgh sleeping quality index (PSQI), visual analogue scale (VAS), disease activity score in 28 joints (DAS28), health assessment questionnaire (HAQ), hospital anxiety and depression scale (HADS), fatigue severity scale (FSS) and a self-designed general status questionnaire.Results The prevalence of sleep disturbance was 42.3% (30/71) in rheumatoid arthritis patients (68.4%).The scores of DAS28, VAS, PSQI, HAQ, FSS and HADS in patients with sleep disturbance were significantly higher than those in patients with good sleep, which were respectively 3.90 ± 1.12 vs 2.92 ± 1.92, (5.03 ± 2.63) scores vs (2.41 ± 1.84) scores, (10.87 ± 2.42) scores vs (4.29 ± 1.85) scores, 3.0 (0.0, 7.0) scores vs 2.0 (0.5,4.0) scores, (39.17 ±14.02) scores vs (29.63 ± 16.12) scores, (14.50 ±7.77) scores vs (9.49 ±6.57) scores (P < 0.05 in all scales).According to the results of Pearson correlation analysis, PSQI had significantly positive correlation with DAS28 (r =0.462, P < 0.01), VAS (r =0.556, P < 0.01), HAQ (r =0.360, P < 0.01), FSS(r =0.420, P < 0.01) and HADS (r =0.447, P < 0.01) respectively.The logistic regression analysis indicated that VAS was a predictor for poor sleep quality (P < 0.01).The patients receiving biological agents had significantly (P < 0.05) lower scores of DAS28 (2.86±1.39 vs 3.52 ± 1.1 0), PSQI [(5.90 ± 4.24) scores vs (8.53 ± 3.78) scores], VAS(2.15 ± 2.30 vs 4.05 ± 2.46), HAQ [0.0 (0.0, 2.0) scores vs 3.0(0.0,6.0) scores] compared to those taking oral drugs.Conclusion High prevalence of sleep disturbance in patients with RA is noted, which indirectly influences the activity of disease, quality of life, depression, fatigue and other physical and mental health.Biological agents can partly improve the sleep disturbance and functional status.
