Objective To explore the medical coping strategies and impact factors of patients with coronary heart disease in Wuhan.Methods Both medical coping strategies and impact factors of 90 patients with coronary heart disease in Wuhan were analyzed by using Spearman coefficient and multiple linear regression analysis,and compared with the norm of 701 cases.Results Compared with the norm,patients with coronary heart disease in Wuhan preferred less facing coping strategies and more avoidance coping strategies:(17.89±2.67) points vs.(19.48±3.81) points,(16.95±2.54) points vs.(14.44±2.97) points,and there were significant differences (t=2.146,P=0.035;t=1.994,P=0.048).The yielding coping strategies was indicated insignificant differences (t=1.758,P=0.173).The facing coping strategies were correlated with age (r=-0.212,P=0.036),education levels (r=0.190,P=0.041),family monthly income (r=-0.106,P=0.049) and disease course (r=0.327,P=0.017).The avoidance coping strategies were correlated with marital status (r=-0.304,P=0.013).The yielding coping strategies were correlated with length of disease(r=0.294,P=0.023)and therapy methods (r=0.308,P=0.017).Conclusions Based on patients' characteristics and impact factors,nursing staff should guide and encourage patients to use positive medical coping styles.

Objective To establish a stable and fast method for primary culture of mouse cardiomyocytes. Methods Dishes were coated with polylysine firstly.A two-step approach was used to isolate and digest mouse cardiomyocytes cells (0.25%trypsin in 4°C overnight and 0.5 mg/mL to 1.0 mg/mL collagenase +5 mg/mL albumin collagen digestion liquid in 37°C for short-time digestion), then the cardiomyocytes were purified through differential adhesion for 70 min and 5-bromodeoxyuridine ( BrdU) .The cell morphology was observed under an inverted microscope. The survival rate of cardiacmyocytes was detected by trypan-blue staining and their purity was identified by α-actinin immunofluorescence staining.Results The cardiomyocytes were in good shape and pulsed spontaneously.The survival rate of the cardiomyocytes reached 98%and the purity was 95%.Conclusions This method described in this study is an ideal method for primary culture of mouse cardiomyocytes with a high survival rate and high purity.

Objective To discuss the correlation between nutritional megaloblastic anemia and homocysteine,in order that e-valuate the application of homocysteine in some aspects that detection and treatment of megaloblatic anemia.Methods The study was divided into three groups,included case group (MA group,n=192,including megaloblatic anemia of vitamin B12 deficiency,n=60;megaloblatic anemia of folic acid deficiency,n=69;megaloblatic anemia of folic acid and vitamin B12 defi-ciency,n=63),matched group (heathy persons,n=200)and treated group (persons who recovered from megaloblatic ane-mia,n=192).Results The difference on homolevel in plasma between case group and matched group had statistical sidnifi-cance (t=3.56,3.21,2.78,P <0.01).The difference on homocysteine level in plasma between treated group and matched group had no statistical sidnificance (t=1.23,0.98,0.77,P >0.05).The Hcy levels of folic acid deficiency vitamin B12 de-ficiency,vitamin B12 deficiency and folic acid and vitamin B12 deficiency had no statistical sidnificance (t=1.42,P >0.05). Conclusion The homocysteine level of patients who had nutritional megaloblatic anemia higher than heathy persons.High level of homocysteine had correction between the nutritional megaloblatic anemia.The lack of some nutrition facters (eg:fo-lic acid,vitamin B12)can lead to high homocysteine disease.Detecting the change of homocysteine level in plasma can guide the treatment of nutritional megaloblatic anemia.

Objective To investigate the clinical characteristics of patients with polymyositis(PM) and dermatomyositis (DM), and compare the differences of PM/DM to help the understanding of clinical diagnosis and treatment. Methods One hundred and forty-five hospitalized PM/DM patients from Department of Rheumatology of the First Affiliated Hospital of Xiˊan Jiaotong University were collected from May 2008 to December 2014, and the clinical manifestations, muscle enzymes, electromyogram, muscle biopsy, treatment outcome were retrospectively analyzed. Mann-Whitney U test and χ2 test were used for statistical analysis. Results The most common initial symptom of PM was muscle weakness, accounted for 51.2%, while rash was the initial presentation in most DM patients(43.1%). The incidence of interstitial lung disease (ILD) (62.7% vs 39.5%, χ2=11.009, P=0.001), and the elevation of CRP (48.9% vs 26.8%, χ2=10.272, P=0.001) were all higher in DM than PM, while the elevation of level of CK (85.4% vs 61.8%, U=-2.668, P=0.008) and CKMB (82.9%vs 41.2%, U=-3.303, P=0.001) were more common in PM compared with DM. The pathological study showed degeneration of muscle fiber, connective tissue hyperplasia in most PM patients, and perimysium atrophy, vacuoles degeneration, muscle bundles, perivascular inflammatory cell infiltration were observed in most DM patients. During the follow-up, the clinical remission rate was 57.5%, the relapse rate and the mortality rate was 7.5%and 31.1%respectively. The mortality rate was higher in DM than PM (34.6% vs 21.4%, χ2=4.861, P=0.027). Infection and tumors were the major causes of death, and the lung was the most common site of infection. Conclusion Differences in the clinical features, muscle enzymes, CRP level, pathology and the mortality rate between PM and DM are evident, while ILD, infection and the higher mortality rate are more common in DM than in PM.

A series of surveillance and management actions was taken to minimize out-of-plan re-operations. These actions include: 1) Building and completing the surveillance and management mechanism against unplanned re-operations; 2) Building a real-time surveillance and reporting mechanism; 3) Enhancing quality control and continuous improvement at the operating departments; 4) Enhancing the supervision on regulations implementation by quality control departments of the hospital; 5) Enhancing quality control for medical records; 6) Building a feedback mechanism for surveillance results; 7) Building a penalty and reward mechanism. Efforts for one year and a half on such surveillance and management proved successful, as the incidence of out-of-plan re-operations fell from 1.7% before these actions to 1.0% afterwards.

ObjectiveTo evaluate the nephroprotective effects of transplanting metanephric mesenchymal cells (MMCs) into the renal subcaspsule of rats with acute tubular necrosis (ATN) induced by gentamicin. MethodsMMCs were expanded in culture and immunocytochemistry was used to characterize the cells. After gentamicin-induced ATN, fluorescence-labeled cells were transplanted and traced in kidney tissues by fluorescence microscopy. Serum creatinine (Scr) and N-acetyl-b-D-glucosaminidase (NAG) were tested. Kidney pathology was studied by hematoxylin-eosin staining. Apoptosis was examined by the TUNEL assay. Ki-67 and Bcl-2 expression was examined by immunohistochemistry. ResultsMMCs were expanded in culture and the phenotype of the cells was vimentin-positive and keratin-negative. Compared with other ATN groups, in the MMCs-treated group, Scr and NAG clearly decreased[14d Scr: (101.38±20.46) μmol/L vs (248.78±23.15), (252.98±33.52), (229.08±18.18) μmol/L;NAG: (14.83±7.74) U/L vs (33.33±14.88), (29.62±10.54), (30.22±10.94) U/L, P<0.05, respectively];the histopathoiogic lesion scores were lower (P<0.05);the Ki-67 antibody and apoptosis of renal tubular epithelial cells were improved or reduced respectively;the expression of Bcl-2 protein was up-regulated (P<0.05). ConclusionThe subcapsular transplantation of MMCs can ameliorate renal function and repair kidney injury.

We present a case of autoimmune chronic pancreatitis in a previously healthy child without any history of autoimmune disease. A 12-year-old boy was admitted to the hospital with abdominal pain. The serum amylase, lipase, and IgG levels were elevated and autoantibodies (antinuclear antibody, antineutrophil antibody) were detected. An abdominal CT (computed tomographic) scan revealed diffuse enlargement of the pancreas. ERCP (endoscopic retrograde cholangiopancreaticography) demonstrated an irregular stricture of the main pancreatic duct in the pancreas tail. After two years of oral steroid and immunosuppressive drug therapy, the clinical, laboratory and radiological findings were improved. The patient has been symptom-free for 18 months after the discontinuation of medication.
