Objective To approach the reason and treatment of arrhythmia after total pneumonectomy. Methods 94 arrhythmic cases after total pneumonectomy surgery were reviewed, the arrhythmia's clinical types, developing reasons and treatment process were summarized. Results There are 34 arrhythmic cases (36.2%) in all the 94 patients, most of them are sinus tachycardia. The incidences of arrhythmic are about 22.5 % and 78.3 % for normal and abnormal ECG patients before operation. The incidences of arrhythmic are also about 24.2% and 28.1% for using PCEA or not using any pain killers after surgery. Conclusion Arrhythmia after total pneumonectomy was influenced by patients' age, previous medical history, suffered hypoxemia during operation and high cardiac irritability. Using interventional treatment for patients with cardiovascular disease before operation, give enough oxygen, keep respiratory tract ease and smooth and using analgesia can significantly decease the arrhythmic incidence after total pneumonectomy.

Objectives:To investigate the expression of regulators survivin and Ki 67 in rhabdomyosarcoma(RMS), and to evaluate their relationship with clinicopathological features. Methods: Immunohistochemical technique(S P) and image analysis were used to detect the expression of regulators survivin and Ki 67 in 43 cases of RMS and 10 normal skeletal muscles. Results: Expression of survivin was detected in 86% of the RMS, with higher levels in RMS than in normal skeletal muscles ( P

ncing analysis validated that all four-type base-quenched probes could provide unbiased genotyping results ( Kappa =1, P=0.00), although. Conclusion This method is simple, economic and suitable for large-scale genotyping studies.

AIM:To determine whether the vitreous cavity (VC) is capable of supporting the induction of deviant immune response to retinal soluble (S) antigen and to observe the influence of interleukin-1 (IL-1) on the immunologic properties of the VC. METHODS: Retinal S antigen was inoculated into the anterior chamber (AC) and VC in Wistar rats. Seven days after antigen inoculation, the recipient animals were immunized with S antigen and complete Freund's adjuvant. Delayed-type hypersensitivity (DTH) was then assessed by footpad challenge. To alter systemic immune conditions, IL-1 was administrated by intraperitoneal injection. RESULTS: Antigen-specific DTH did not develop in rats in which S antigen was injected into the AC and the VC. In contrast, strong DTH was elicited by S antigen injected into the AC and VC if IL-1 was administrated systemically for 7 consecutive days after the antigen challenge. CONCLUSION: The VC is capable of supporting immune deviation to soluble antigen by actively suppressing antigen-specific DTH. Systemic administration of exogenous IL-1 eliminates the capacity of the VC to support immune deviation inducing by soluble antigen injected locally.

Objective To study the growth effect of human cholangiocarcinoma cell line QBC939 treated by norcantharidin (NCTD) and preliminary illustrate the potential mechanism.Methods The human cholangiocarcinoma cell line QBC939 was detected by MTT assay,flow cytometry,immunocytochemistry after the treatment of NCTD in vitro.Results NCTD displayed inhibitory effect on growth of QBC939 from different doses of 0.125,0.75,2.5,10,120 μg/ml after 48 h (P ＜0.05).It was in a dose and time dependent manner.Dose-effect curve was drawn and IC50 value was (3.66±1.14) μg/ml.The flow cytometric profiles showed that the rate of cell apoptosis enhanced following increasing the concentration of NCTD[(8.6±0.4) ％,(17.6±0.3) ％,(22.9±0.4) ％,(25.5±0.9) ％ and (31.1±1.5) ％,respectively]and cells blocked in the G2/M phase after treatment with 2.5 μg/ml NCTD[(14.1±1.0) ％ and (5.7±0.3) ％].The expression of the protein caspase-3 elevated after different concentrations of NCTD co-cultured with QBC939 compare with contrast group.Conclusion NCTD has an inhibitory effect on proliferation of QBC939 cell line,and the mechanism might be related to the induction of cell apoptosis and blockade of cell cycle.

Objective Experimental autoimmune anterior uveitis (EAAU) is a useful model for human anterior uveitis. The purpose of this study was to observe whether EAAU development could be prevented by anterior chamber-associated immune deviation (ACAID). Methods Bovine melanin protein (BMP) in phosphate-buffered saline (PBS) was injected into the anterior chamber of the right eye of rats; control animals were injected with PBS alone. Seven days later, all animals were immunized with BMP in complete Freund's adjuvant (CFA) and pertussis toxin. The severity and incidence of uveitis was monitored by clinical examination and histopathology. The delayed-type hypersensitivity (DTH) responses were evaluated by footpad swelling elicited by injection of BMP.Results Rats intraocularly injected with BMP showed a reduced severity and incidence of EAAU, and significantly suppressed DTH response compared to control rats.Conclusion These data suggest that the ACAID procedure can be utilized to prevent the development of EAAU.

Objective To develop a duplex fluorescence RT-PCR assay for detection of scavenger receptor class B, typeⅠ(SRBⅠ) knockout mice. Methods Primers and probes were designed according to knockout region of SRBⅠgene and related substituted sequence. DNA samples were extracted from tails of mice and performed amplification using real-time PCR. SRBⅠgenotypes of mice were analyzed according to amplification curves of FAM and CY5 channels. Finally, the sensitivity of the method was detected and the accuracy was verified by the direct sequencing. Results The homozygous SRBⅠwild genotype showed an amplification curve only in FAM channel. When the homozygous SRBⅠknockout genotype was present, the typical S amplification curve appeared only in the CY5 channel. Heterozygous genotype showed two typical S amplification curves in both FAM and CY5 channels, respectively. The results showed that the sensitivity reached 4×101 copies/μL, and there was complete concordance between this method and direct DNA sequencing. Conclusion The new method is simple, rapid and accurate, which is suitable for genotyping SRBⅠknockout mice.
