In the past 10 years, 118 cases with primary congestive cardiomyopathy of first admittance to this institution were treated.12 cases died in the course of hospitalization. Out of the 106 cases discharged after clinical recovery, 91 cases were followed up. In the follow-up period, 1 year survival rate was 85.25%, 2 year survival rate 67%, 5 year survival rate 43.7%, and 10 yaar survival rate 25.5%, as calculated with the life-span table method. The results suggest that the remote prognosis of this disease is poor. The factors influencing the prognosis of this disease were the age of the patient, the heart size, and the status of heart functions. Severe and complicated cardiac arrhythmias could worssen the outlook of the patient even though no heart failure occurred. Early and long term administration of vessel-dilatating agent such isoscorbide dinitrate can improve the prognosis but steroid therapy has no effect.

Objective:To investigate the risk of heparin leading to upper gastrointestinal bleeding in elderly patients undergoing percutaneous coronary intervention(PCI).Methods:To compare characteristics of unfractionated heparin and low molecular weight heparin,the dosage and lab indexes.Results:The upper gastrointestinal bleeding is easy to happen in elderly patients with disease of digestive tract when using heparin in PCI.Conclusion:The patients before undergoing PCI,especially the elderly,need to have a general examination,make an overall assessment with care to digestive disease.Doctors should pay more attention to the heparin dosage and lab indexes in order to avoid serious complications.

Objective:To identify the influence of personality characteristics on adult patients' satisfaction after initial orthodontic treatment and offer references to rise quality of orthodontic treatment.Methods:85 patients(34 males and 51 females;average age 23.3years?4.4years who treated their teeth by fixed orthodontics were included in the study.Satisfaction questionnaire was used to assess the satisfaction with the dentition in the study sample.The NEO Five Factor inventory was used to assess personality profiles and traits in the study samples.Comparisons between groups were made by using Logarithm of likelihood ratio test.Results:This test provides a comprehensive assessment of personality according to the five major domains namely Neuroticism,Extroversion,Openness,Agreeableness and Conscientiousness.Satisfaction of higher neuroticism scores is relative low(P0.05).Conclusion:Different personality traits were found to be correlated with adult patients' satisfaction with their dentition during initial orthodontic treatment.The orthodontists should pay more attention to higher neuroticism scores adult patients during treatment.In according to strengthen the communication between the orthodontists and outpatients,the therapeutic effect of adult orthodontic treatment could be increased.

Objective:To explore a method for pericardiocentesis and drainage,the duration,posture of drainage and the fluid volume by drainage.Methods:Forty patients half lying on the bed,the puncture was performed via the subxiphoid route after the site,depth and direction of needle entry were confirmed by echocardiography.Using seldinger method,we put the central venous indwelling catheter into pericardial sac and connect it with an aseptic bag for drainage.Results:Catheter pericardiocentesis in 40 patients was successful without complications.Duration of use of the indwelling pericardial catheter ranged from one day to seven days,the average is 1.5?2 days.The fluid volume removed was one hundred and eighty to two thousands milliliters,mean volume is 750?600ml.After drainage,chest discomfort and short breath were alleviated obviously.Prominent jugular veins disappeared.Reductions of heart rate were significant.Cardiac function improved.Conclusion:Seldinger technique is a safe method for pericardiocentesis and drainage with the assistance of echocardiographic diagnosis and guidance.It can avoid myocardial trauma and drain the pericardial effusions effectively.

Objective:To compare the effects of simvastatin,xuezhikang and pravastatin in patients with primary hyperlipidemia.Methods:Sixty patients were randomly divided into three groups,simvastatin 20mg were taken once a day at night;provastatin 10mg were taken once a day at night;xuezhikang 0.6g were taken twice a day in the morning and at night.Blood samples were taken before and 4 weeks,8 weeks,12 weeks after the treatment.Results:In simvastatin group:the serum levels of total cholesterol(TC),low-density lipoprotein cholesterol(LDL C) decreased markedly at the end of 4 weeks compared with those of the baseline ( P 0.05).In xuezhikang group:after 4 weeks of treatment,TC,TG,LDL C reduced markedly( P 0.05).From the change rates,we can see after 8 weeks,12 weeks of treatment the level of LDL C drcreased more significantly in simvastatin group (40%,45%) than in xuezhikang (31%,36%) and provastatin (31%,35%) ( P 0.05).Conclusion:The clinical effects of simvastatin,xunzhikang,provastatin on primary hyperlipidemia were equal among the three groups,but the time is different about when they take great effects respectively.Next,LDL C lowering effect of simvastatin was significant.Finally,xuezhikang was the best in reducing TG among the three groups and it has a relatively good economic effectiveness.

Objective:To study the optimal intensity of warfarin therapy for prevention of thromboembolism in elderly patients with nonvalvular atrial fibrillation and to determine the safe range of INR.Methods:Warfarin was used for anticoagulant therapy for thirty-seven patients with nonvalvular atrial fibrillation.The patients were followed up and INRs were measured regularly.Results:When the dosage of warfarin changed from 2.11 milligram to 2.41 milligram,the range of INR was between two and two point five (2.0～2.5).When the dosage changed from 2.41 milligram to 2.70 milligram,the INR was between two point five and three (2.5～3.0).No atrial fibrillation related thromboembolism and major hemorrhage occurred in all patients.It required different number of days to reach the safe INR limits by raising or lowering the dosage of warfarin in the patients.Conclusion:Warfarin is effective in preventing stroke in elderly patients with nonvalvular atrial fibrillation.The optimal intensity of warfarin ranges from 2.11 milligram to 2.41 milligram and the safe range of INR is between two and two point five (2.0～2.5).

MicroRNAs (miRNAs or miRs) are a class of small non-protein-coding RNAs, approximately 18 to 25 nt long. MicroRNAs can act as endogenous RNA interference. MicroRNAs can posttranscriptionally regulate the expression of hundreds of their target genes, controlling a wide range of biological functions such as cellular proliferation, differentiation, and apoptosis. MicroRNAs can posttranscdptionally regulate the expression of genes by hybridizing to complementary sequences in 3' UTR (3' untranslated region) of target messenger RNA (mRNA), repressing the translation of mRNA or increasing the instability of mRNA. A number of miRNAs are mapped to cancer-associated fragile regions (FRAs) as well as in minimal regions of loss of heterozygosity, minimal regions of amplification, or common breakpoint regions in the genome, suggesting that miRNAs might be involved in tumorigenesis. Many miRNAs are up or down-regulated in cancers as potential oncogene or tumor suppressors. It has been considered that the mutation of a series of oncogene or anti-oncogene gradually causes tumorigenesis. The conventional points of view were changed with the finding of non-protein-coding RNAs. MiRNA as members of non-protein-coding RNAs may play an important role in regulating tumor formation. Recent studies have in-vestigated the relationship of miRNAs with neoplasia, development, treatment and prognosis. Lung cancer is the leading cause of cancer-related deaths all over the world. Its etiology is primarily genetic and epigenetic damage caused by tobacco smoke. Systematic analysis of RNA and protein expression levels of thousands of genes has also contributed to defining the molecular net work of lung carcinogenesis. MiRNAs are closely related to lung cancer and play an important part in the diagnosis, therapy, surveillance and prognosis of lung cancer. We reviewed some miRNAs closely associated with lung cancer such as miRNA-126, miRNA-221, miRNA-222, has-mir-221, a polycistronic microRNA cluster miR-17-92, miRNA-128b, has-mir-137, has-mir-182, has-mir-372 and miRNA let-7. We summarized the roles of miRNAs in the genetic susceptibility, invasion or metastasis, diagnosis, therapy and prognosis of lung cancer.

Objective:To investigate the intervention effect of vitamin C for the treatment to diabetes patients with diabetes and gastric ulcer.Methods: 53 cases of patients with diabetes combined with gastric ulcer were selected as the research subjects, and were divided into a control group(23) and a intervention group(30). The patients in two groups were given the treatment of reducing blood sugar and anti-HP triple therapy. The intervention group was given additionally diet intervention via eating vitamin C. The blood sugar, blood lipid levels, gastric ulcer index and inflammatory markers of the two groups were reviewed six months later by helicobacter pylori type detector. And the statistical analysis was performed.Results: After treatment, the blood sugar, blood lipid levels, gastric ulcer index and inflammatory markers of the two groups were significantly improved (t=1.23,t=1.35,t=2.63,t=1.07,t=0.77,P<0.05), except for the HP cure rate (P>0.05). Other indexes of the intervention group are significantly better than the control group (t=1.45,t=1.67,t=2.33, t=1.55,P<0.05).Conclusion:Vitamin C play a very good role in the treatment and prevention for the blood sugar, the blood lipids, gastric function and inflammation of patients with diabetes and gastric ulcer, and helicobacter pylori type detector can simplify the detection of helicobacter pylori.
