Objective To study the prediction value of C-reactive protein (CRP) level to ankylosing spondylitis disease activity score (ASDAS),the most widely used activity score in ankylosing spondylitis (AS).Methods A total of 386 patients with AS were enrolled and divided into 2 groups by CRP≥3.5 mg/L (n =266) and CRP ＜ 3.5 mg/L(n =120).ASDAS-CRP was evaluated in patients with CRP below the normal range (3.5 mg/L) in different subgroups.Three methods were used to test the consistency between ASDAS-CRP and ASDAS-erythrocyte sedimentation rate (ESR).Results The ASDAS-CRP showed a good correlation with the ASDAS-ESR when CRP level was ≥ 3.5 mg/L (r =0.899,P =0.000).In the group of CRP ＜ 3.5 mg/L,ASDAS-ESR showed better consistency with ASDAS-CRP when CRP level was below 1.5 mg/L(intra-class correlation coefficient 0.902;kappa coefficient 0.70).By the evaluation of variant gradient matrix,CRP 1.5 mg/L coincided with disease activity states.Conclusion There is good consistency between ASDAS-CRP and ASDAS-ESR.When CRP level is below the normal range,1.5 mg/L could be a cut-off value to calculate the optimal ASDAS-CRP score.

Objective To summarize the experience in treating coronary artery fistula (CAF) by using Guglielmi detachable coils. Methods During the period from July 2009 to November 2014 at the Affiliated Changhai Hospital of Second Military Medical University, interventional treatment of CAF by using Guglielmi detachable coils was performed in 40 patients. The clinical data were retrospectively analyzed. The feasibility, safety and effectiveness of this technique were evaluated. Results Successful transcatheter closure of CAF with Guglielmi detachable coils was achieved in all 40 patients; the average Guglielmi detachable coils used in each patient was(2.33±1.38) coils. No procedure-related complications occurred. Intra-operative angiography showed that residual shunt completely disappeared in 12 patients (30%) and blood flow was significantly decreased in 28 patients (70%). All the patients were followed up for 1-65 months, neither complications such as recurrent bleeding and ischemia nor stenosis and occlusion of related arteries, or fistula cavity rupture occurred. Conclusion The use of Guglielmi detachable coil in interventional treatment of CAF is safe and effective, although its long-term effect needs to be further verified.

Objective The aim of this study was to determine the effect of a new method of cardiac assistant therapy with an extra-aortic balloon pump on the experimental dogs in which myocardial ischemia or infarction were induced, and to ob serve its effectiveness and feasibility. Methods Twelve animal models of myocardia 1 infarction were established with the method of left anterior descending coronary artery ligation. They were divided randomly into two groups, six in the experimental group and six in the untreated group. The end points observed were the differences between the two groups in the blood pressure, cardiac function, myocardial enzymes, infarction size and routine blood variables before procedure, 1,2, 3, 4, 5 and 6 hours after myocardial infarction. Results All six dogs in the experimental group were survived, with a mortality rate of 0.The number of death in the control group was three, with a mortality rate of 50%. Measurements such as mean blood pressure,cardiac output, cardiac index in the experimental group were better than those in the control group ( P ＜ 0.05 ). Mean heart rate before myocardial infarction in the experimental group was 156 beats per minute, as compared with 148 beats per minute in the control group, and was 128 vs. 67 beats per minute respectively six hours after myocardial infarction. The cardiac output was 3.48 vs. 4.98 liters per minute before myocardial infarction and was 6.10 vs. 0.85 liters per minute six hours after myocardial infarction. The average pressure was 94 mm Hg vs. 99 mm Hg before myocardial infarction and was 70 mm Hg vs. 33 mm Hg six hours after myocardial infarction. Conclusion The extra-aortic balloon pump significantly improved the hemodynamic variables of the experimental animals after myocardial infarction and reduced mortality. Injury to the blood cells may be the potential disadvantage.

Objective To evaluate the association between interleukin-I(IL-1)loci polymorphisms and increased risk of gastric carcinoma in samples from northern Chinese population.Methods Blood sam- ples from 126 patients with gastric cancer and 125 controls with chronic gastritis were collected.Genomic DNA was extracted and polymorphisms at -31(C to T),-511(C to T)and at intron 2(86-bp VNTR)of IL-I RN were genotyped by PCR-CTPP,PCR-RFLP and PCR.For detection of Hp infection fast urenase test,~(14)C breath test and serum anti-Hp IgG antibody assay were used.Results Five kinds of polymorphism of IL-IRN were found as 1/1,1/3,1/4,1/2 and 2/2,and the frequencies in patients were 76.19%、4.76%、6.35%、11.90% and 0.79%,respectively.However,the frequencies in controls were 76.00%、4.00%、4.80%、13.60% and 1.60%.No significant differences were observed between cases and controls in each genotype.The polymorphism of IL-IB-31 allele was C/C,C/T and T/T.The frequencies in patients were 12.70% ,47.62% and 39.68%,and in controls 28.00%,48.80% and 23.20% respectively.IL-1B- 31 T/T carriers were at an increase risk of gastric cancer with an odds ratio of 3.772(95% CI,1.786- 7.966).IL-IB-511 alleles were C/C,C/T and T/T.The frequencies in patients were 19.20%,56.80% and 24.00% and in controls,23.38%,49.19% and 27.42% respectively.No significant differences were observed between cases and controls in each genotype.Conclusion In Chinese population,the polymor- phism of IL-1B-31 alleles may be associated with the susceptibility of gastric cancer.However,no evidence was found to support that the polymorphisms of IL-1RN and IL-I B-511 alleles had relationship with gastric cancer.

Objective To investigate the role of survivin and P53 in apoptosis of gastric adeno- carcinoma,as well as its relationship with the clinicopathologic features and the prognosis.Methods The gas- tric tissue microarrays were composed of those from 100 cases of gastric cancer and 30 controls.At these tissue microarrays,expressions of survivin and P53 were investigated immunohistochemically,and tumor cell apoptosis index was examined by TUNEL method.Of the 100 cases,47 cases were followed-up from 14 months to 13 years,in which the survival was analyzed.Results Two paraffin-embedded gastric carcinoma tissue micro- arrays were successfully constructed,including 114 and 116 tissue spots,respectively.Immunohistochemical analysis showed that survivin was expressed in 78 cases (78%).No expression of survivin was detected in control tissue (P0.05).In the 47 cases with followed-up data,univariant analysis revealed that the survival was correlated with invading of vessel and nerve,TNM stages,and expression of survivin.The histological grades and expression of P53 were not related to prognosis.However,Cox stepwise proportional hazards analysis showed that only TNM staging and survivin status retained significant independently in prospecting prognosis.Conclusions The expression of survivin was associated with the pathologic features,TNM stages and prognosis in gastric carcinoma,indicating that overex- pression of survivin may be a poor prognosis factor for gastric carcinoma.

Clinical medicine is a comprehensive discipline integrating natural science and hu-manities and social science. Lemology is closely related with basic medicine and medical microbiology and medical immunology are the basis of lemology. Therefore, in the process of cultivating postgradu-ates of lemology, we should not only should attach importance to the cultivation of basic medical knowl-edge and clinical professional quality, but also pay more attention to the development of the intelligence factors and non-intelligence factors. Meanwhile education on humanity, social sciences and relevant laws and regulations should be enhanced to cultivate doctors' professional quality. Reverse thinking and lateral thinking in the clinical diagnosis should be strengthened to achieve the training objectives of cultivating international medical talents.
