Objective Cardiovascular diseases comorbid with mental disturbances are described as psycho-cardiology diseases, which have been paid attention increasingly. The aim of this study is to summarize and analyze the findings about the study of psycho-cardiology over a year , and to obtain the baseline data of psycho-ca rdiology diseases in inpatients of cardiology department. Methods Subjects in this study were inpatients of cardiology department in the First Affiliated Hospital of Kunming Medical University in the past 21 months. The demographic and clinical data of the inpatients were collected. Anxiety and depression were evaluated by the Hospital Anxiety and Depression Scale. The prevalence of anxiety and depression in patients with various cardiovascular diseases were calculated respectively. To detect the potential risk factors of anxiety or depression, two logistic regression models were established. Results The prevalence of anxiety, depression, anxiety and/or depression, and anxiety comorbid with depression was 38.6%, 12.4%, 51.0%, and 7.9%,respectively. The prevalence of depression in patients with chronic heart failure was 24.6%, which was higher than the general level and that of patients with other cardiovascular diseases. The prevalence of anxiety in patients with acute myocardial infarction, arrhythmia, and hypertension ranged from 39.6% to 41.7%. The long course of diseases, multiple diseases, and the history of cardiac interventional operation were the common risk factors for anxiety and depression. Conclusion Anxiety and depression are common in patients with cardiovascular diseases. Cardiologists should take mental disturbances seriously, and pay more attention to the patients with above risk factors.

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.

Neurotensin receptor-1 (NTR1), which can stimulate the intracellular cascade signal pathway, belongs to the large superfamily of G-protein coupled receptors. NTR1 is related to the occurrence and development of several kinds of diseases. In order to screen the inhibitors for the cancers associated with NTR1 protein, we established a CHO (Chinese hamster ovary) cell line in which human neurotensin receptor-1 was highly expressed. The method is to construct the recombinant plasmid which was lysed with the hNTR1 gene and transfect it into CHO cells. After selected with G418, the cell line was evaluated by Western blotting analysis and calcium flux assays. Through the calcium flux assays on FlexStation 3, we got the EC50 value of neurotensin peptide which is the natural NTR1 agonist, and the IC 50 value of SR48692 which is the known NTR1 antagonist. The established human CHO/NTR1 cell line can be used to study the profile of NTR1 biological activity and further screen of NTR1 antagonists and agonists.

Objective To analyze the sequence of microsatellite and the flanking sequence from four populations of Oncomelania hupensis. Methods We cloned 159 SSR-PCR amplification products of a commonly used primer, (CA)8RY, using O. hupensis genomie DNA as template, and sequenced 82 products Results The sequences obtained were novel O. hupensis genomic sequences but not repeat simple sequence. It was observed that 36 out of 82 clones contained microsatellites between priming sites.The flanking sequences of certain microsatellite were invariant. Both (GA/CT). and (TTAGGG/CCCAA)n were found in four populations of O. hupensis. However, (CAA)n were found only in O. hupensis from Fuqing,Fujian province and (TCTCTG), were found only in O. hupensis from Guichi,Anhui province and (GAA/TTC)n, (CAA/TTG)n, (CAT), were found only in O.hupensis from Puge,Sichuan province. Conclusion The results obtained by SSR-PCR should not be interpreted as the amplification of microsatellite loci, and analytical rules similar to those for Random Amplified Polymorphic DNA should be used. SSR-PCR could not make the most of the priority of microsatellite. It seems better to amplify the microsatellites with the primers designed on the basis of the flanking sequence.

Background Research demonstrated that mitochondrial pathway plays a key role in cell apoptosis.Purendan supermicropowder(PRD),a traditional Chinese medicine,may be a potentially effective therapy for neuron apoptosis in diabetic retina.Objective This study was carried out to investigate the effects of PRD on aldose reductase(AR)activity,neuron apoptosis and mitochondrial pathway in retina of diabetic rat.Methods Thirty-six clean male Wistar rats were randomly divided into normal control group,diabetes model group,PRD treatment group randomly and 12 rats for each group.The diabetes models were established by intraperitoneal injection of 25 mg/(kg · d)streptozotocin(STZ)for 3 consecutive days,and blood glucose ≥ 16.7 mmol/L was taken as the standard.PRD solution of 1.8 g/(kg · d)was lavaged in 12 models for 3 months.The eyeballs were enucleated for the preparation of retinal tissue homogenate and slice.AR activity in the retina was detected by ultraviolet spectrophotometry,and neuron apoptosis in retina was assayed by TUNEL staining.Western blot was used to assess the expressions of bcl-2,bax,cyt-c and caspase-3 protein in the retina.The use of animals followed the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Committee(Version 1988).Results Statistically significant differences were found in AR activity and AI among the normal control group,diabetic group and PRD groups(F=90.115,165.540,P＜0.01),and those of diabetic group were evidently higher than the normal control group and PRD group(P＜0.01,P＜0.01).The positive TUNEL cells mainly located in inner nuclear layer and retinal ganglion cell layer.The expressions of bax,cyt-c,caspase-3,bcl-2 and bcl-2/bax in retina were obviously different among these three groups(F =51.332,41.262,25.888,38.564,47.870,P＜0.01),and the expression of bax,cyt-c and caspase-3 protein in diabetic group evidently elevated in comparison with the normal control group and PRD group(t ＝ 10.32,11.04,6.91,P ＜ 0.01)and the expressions of bcl-2 protein and bcl-2/bax value were significantly lower in diabetic rats than in the normal control rats(t =18.05,12.23,P＜0.01).AR activity by AI of retina,the expressions of bax,cyt-c and caspase-3 proteins in retina were obviously lower in PRD group than in diabetes model rats(P ＜ 0.01),and the expression of bcl-2 protein and bcl-2/bax value were significantly higher in PRD group than in diabetes group(P＜0.01).Conclusions PRD can protect retina against the damage caused by high glucose by suppressing AR activity by downregulating the expressions of bax,cyt-c,caspase-3 proteins,increasing the expressions of bcl-2 protein in retina of diabetic rats and further inhibiting the mitochondrial pathway and reducing cell apoptosis in retina of diabetic rats.

Objective To analyse the characteristics of orbital benign and malignant masses on diffusion weighted imaging in combination with conventional MR imaging and evaluate the diagnostic value of apparent diffusion coefficient in distinguishing benign and malignant orbital lesions.Methods Seventy- seven cases with orbital masses,including fifty-five benign lesions and twenty-two malignant tumors,who underwent conventional MRI and diffusion imaging scanning were studied with use of a 1.5 T magnetic resonance system.Quantitative ADC measurements of masses(ADC_M)and of the white matter of eontralateral temporal lobe(ADC_W)were made with two different b-values of 0 and 1000 s/mm~2.The ADC ratio(ADCR)of the lesion to the control was calculated.The receiver operating characteristic curves(ROC) were constructed using various cut points of ADC_M and ADCR for different parameters to differentiate between benign and malignant masses.The area under the ROC curve for each parameter was also calculated. Results All cases were proved by histopathology.The mean ADC_M and ADCR of benign orbital masses were(1.56?0.75)?10~(-3)mm~2/s and 1.85?0.91,respectively.The mean ADC_M and ADCR of malignant orbital masses were(1.09?0.42)?10~(-3)mm~2/s and 1.28?0.53,respectively.There were significant difference both between ADC_M and ADCR of benign and malignant masses(t=2.803,2.735,P

To investigate the therapeutic effects and associated complications of allogeneic peripheral blood stem cell transplantation (allo-PBSCT). 40 patients with various malignant hematopoietic diseases received allo-PBSCT. The preparative regimens were based on BUCY2 or modified BUCY2. The acute graft-versus host disease (aGVHD) was prevented by cyclosporin A and short-term MTX regimen in all patients. Two patients from donors with one fully mismatched HLA on DRB1 locus and 4 from unrelated donor also administered Zenapox (CD25 MAb) at dosage of 1 mg/kg every day on the day before transplantation and day 4 after transplantation. These 6 patients were also treated with mycophenolate mofetil (MMF). Transfusion of the donor cells: The median of the transfused nucleated cells was 5.38 x 10(8)/kg and that of the CD34+ cells was 7.8 x 10(6)/kg respectively. All the patients gained hematopoietic reconstruction except one who died of infection before engraftment. Seven patients got II degrees-IV degrees aGVHI) and the incidence was 17.5%. Fourteen patients got cGVHD and the incidence was 53.8% in the patients who survived over 6 months. Twenty-eight patients had fever or other characteristics of infection. The median follow-up time was 13.8 months. The incidence of transplantation related mortality (TRM) was 17.5% and 2 patients relapsed (5.0%). It was concluded that allo-PBSCT can reconstruct hematopoiesis quickly and is a favorable therapeutic method for leukemia.

To investigate the exon mutation of vitamin K-dependent gamma-glutamyl carboxylase (GGCX or VKDC) in patients with calcium oxalate urolithasis, renal cortex and peripheral blood samples were obtained from severe hydronephrosis patients (with or without calculi), and renal tumor patients undergoing nephrectomy. GGCX mutations in all 15 exons were examined in 44 patients with calcium oxalate urolithiasis (COU) by polymerase chain reaction (PCR) and denatured high pressure liquid chromatography (DHPLC), and confirmed by sequencing. Mutation was not found in all COU samples compared to the controls. These data demonstrated that functional GGCX mutations in all 15 exons do not occur in most COU patients. It was suggested that there may be no significant association between the low activity and mutation of GGCX in COU.
