Objective To discuss the intensive gastric cavitary lavage method in treatment of stress ulcer bleeding(SUB).Methods The therapeutic effects of 100 patients with severe SUB in intensive care unit (ICU)from July 2005 to February 2008 treated with intensive gastric cavity lavage method were observed and analyzed.Results In these 100 cases,the bleeding was stopped successfully in 97 cases,the therapeutic effective rate being 97%;there were 17 cases died of complicated pulmonary infection(17%)and 3 cases of bleeding(3%),the total fatality rate being 20%.All the other cases were cured.Conclusion Intensive gastrointestinal lavage therapy is an effective method as acid inhibitor for treatment of SUB,but it can decrease the inhabitant flora in the stomach to pass through gastric-pulmonary route,thus the incidence of pulmonary infection was reduced.

Objective To investigate the survival rate and the influencing factors in lupus nephritis (LN) patients with neuropsychiatric systemic lupus erythematosus (NPSLE). Methods Clinical characteristics and biochemical markers of 78 patients including 59 variances were analyzed. Patients were followed up from the onset of NPSLE to death. Patient survival rate was estimated by Kaplan-Meier method. Cox regression model was used to analyze influencing factors. Results Sixteen (20.5%) of 78 patients died of SLE or its complications. Infection was the main cause of death (31.3%). One-, 3-, 5- and 10-year survival rates were 83.2%, 81.7%, 76.7% and 76.7%, respectively. Hypertension (RR =6.965,95% CI:1.578-30.746, P= 0.010), pulmonary infection (RR=8.171,95% CI:1.954-34.177, P=0.004)and acute renal failure (RR=6.978,95%CI:2.063-23.609, P=0.002) were risk factors of mortality, while cyclophosphamide (CTX) impulse therapy (RR =0.130,95 % CI:0.031-0.541, P=0.005) and resolution of NPSLE (RR= 0.169, 95%CI:0.042-0.679,P=O.012)were protective factors. Conclusions Infection is the main cause of death in patients of LN complicated with NPSLE. Survival rate of LN patients with NPSLE in this study is lower than those of LN and NPSLE alone reported by other authors. Hypertension, pulmonary infection and acute renal failure are risk factors of mortality, while CTX impulse therapy and resolution of NPSLE reduce the mortality and improve the prognosis.

AIM:To investigate the effect of pretreatment of stem cell factor(SCF) and granulocyte colony-stimulating factor(G-CSF) on the proliferation and the differentiation of mesenchymal stem cells(MSCs) into cardiomyogenic cells.METHODS:The MSCs,isolated primarily from bone marrow,and purified by passage culture,were obtained from the adult rats of four groups:the rats were pretreated by 5 daily injections of SCF;the rats were pretreated with G-CSF;the rats were pretreated with SCF and G-CSF;the rats were treated without any intervention.The 4th passage of MSCs was labeled by DAPI and cellular cycle analysis was conducted by flow cytometry before co-culture.The neonatal rat cardiomyocytes cultured for 3 days were co-cultured with DAPI-MSCs.The percentage of the differentiation of MSCs into cardiomyogenic cells during the five co-culture days was analyzed.The morphologic changes of MSCs and the proteins expression of cardiac myosin heavy chain(MHC) and troponin T(TnT) were recorded respectively with digital microscope camera system and immunofluorescence technique.The percentage of the differentiation of MSCs into cardiomyogenic cells was also calculated.RESULTS:The percentage of MSCs in G0/G1 phase in SCF/G-CSF group was significantly lower than that in SCF group,G-CSF group and the control group.The percentage of MHC protein-positive MSCs in SCF/G-CSF group was markedly higher than that in SCF group,G-CSF group and the control group,and that in SCF group and G-CSF group was significantly higher than control group.The percentage of TnT protein-positive MSCs in SCF/G-CSF group,SCF group and G-CSF group was significantly higher than that in control group.CONCLUSION:SCF and G-CSF show the ability to stimulate the proliferation of MSCs and induce MSCs to differentiate into cardiomyocytes.The combination of using SCF and G-CSF is more effective than using only SCF or G-CSF.

Conclusions pcDNA3-IFN-? can stably expressIFN-? cDNA in the transfected HCC cell strains

BACKGROUND: Mesenchymal stem cells (MSCs) can differentiate into myocardial cells in vitro and in vivo, but the amount is small and directed differentiation rate is low.OBJECTIVE: To explore the effect of stem cell factor (SCF) on promotion of MSCs differentiating into myocardial cells.DESIGN: Opening experiment.SETTING: Institute of Cardiovascular Disease, Xianning College and Department of Cardiology, Tongji Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology.MATERIALS: The experiment was performed at the Experimental Center of Institute of Cardiovascular Disease, Xianning College from October 2003to August 2004. A total of 20 infant SD rats aged 1-2 days were selected for culture of myocardial cells. Another 25 clean adult SD rats were selected and randomly divided into SCF group, blank control group with 12 rats in each group. The left one rat was used for MSCs extraction, culture and purification.METHODS: ①MSCs were labeled with 4', 6-diamidino-2-phenylindole,dihydrochloride (DAPI) before co-culture. SCF was given into rats of the SCF group by subcutaneous injection successively for 5 days, 20 μg/kg per day. Isolated MSCs were co-cultured with myocardial cells that had been cultured for 3 days. Saline of the same volume was given in the blank control group by subcutaneous injection. MSCs without any intervention were co-cultured with myocardial cells that had been cultured for 3 days.②Expressions of MHC α/β and troponin T were recorded and measured with digital micro-camera shot and immunofluorescence technique, respectively. Percentage of DAPI labeled MSCs differentiating into myocardial cells was measured.MAIN OUTCOME MEASURES: ①Growth of MSCs, ②detection of labeling rate of DAPI on MSCs, ③analysis of activity and purity of co-cultured myocardial cells, and ④differentiation of MSCs into myocardial cells after co-culture.RESULTS: ①Bone marrow cell suspension was inoculated in plastic petri dish. Round cells scattered at the bottom of bottle. At hour 24 a few long fusiform shape adhered cells appeared following liquor change, and at day 4 many fusiform shape adhered cells appeared, which entered logarithm increased period. At days 8-12 80% were confluence. The proliferation of passage cells was more rapid. With liquor change and passage, the MSCs were purified gradually. ②Labeling rate of DAPI on MSCs was 100%. ③At 3-day in vitro culture of myocardial cells the percentage of beat cells was 63%, with beat frequency of 40-60 times per minute. Percentage of positive cells of troponin T expression was 75% examined with immunocytochemical technique. ④At co-cultured days 2 and 3, positive percentage of DAPI labeled MSCs expressing MHC α/β was significantly higher in the SCF group than in the blank control group (P ＜ 0.01). At the co-cultured days 3, 4 and 5, positive percentage of DAPI labeled MSCs expressing troponin T was obviously higher in the SCF group than in the blank control group (P ＜ 0.01).CONCLUSION: SCF has markedly accelerating effect on proliferation and differentiation of MSCs.

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 This study on a medium-fidelity simulator (SimMan , Laerdal Medical Corpo-ration,Wappingers Falls, NY, USA) examined the management of unanticipated difficult airway by residents of anesthesiology and the effect of training in this context.Methods 30 residents of anesthesiology were devided into two groups (T and E). There were two scenarios investigated:'can't intubate, can oxygenate'(CI) and'can't intubate, can't oxygenate'(CICO). The E group was trained by scene simulation in the second, fourth, sixth month respectively before and after the training, and the T group received the same situation simulation training on the same day after the theoretical training and in the second, sixth month after the training. In con-trast to standard operating procedures, the performance of two groups of trainees was recorded on the basis of pre established evaluation criteria. Data differences between the two groups were analyzed using SPSS 23.0,t test, M-W test andx2 test.ResultIn CI, success rate of placement of astandard and intubating laryngeal mask air-way were high in T group (87％ vs. 55％ ,P=0.037). This was sustained over time. There was no difference in duration and incidence of desaturation between two groups. In CICO, there was a more structured approach following training in T group (P<0.05), which wasn't sustained over time. But this was sustained over 6 months in E group.ConclusionSituational simulation training can significantly improve the anesthesiology residents' ability to take proper response measures to the unexpected difficult airway, and significantly shorten the training time for emergency airway treatment. Repeated situational simulation training should be conducted at intervals of 2 months or less, allowing residents to maintain emergency response to the emergency airway.

Objective:To explore the optimal postpartum nursing intervention method of elderly second-birth parturient based on the best evidence and evaluate its effect so as to improve the quality of clinical nursing.Methods:Based on the best evidence obtained from the previous study, the optimal nursing examination index of the elderly second parturient was established, and the evidence of best practice was obtained by using the evidence-based nursing method, and the 2017 revised version (the third edition of) Johns Hopkins evidence-based nursing practice model) was used to guide nurses to apply the evidence to clinical practice. During the period from March to May 2019, the baseline review was completed, including 82 pregnant women and 43 nurses. The evidence was incorporated into clinical practice in June 2019. From July to October 2019, the same indicators and inclusion and exclusion criteria were used to evaluate the effectiveness of evidence application in 43 nurses (including midwives) and 85 elderly second-child parturients in obstetric wards (including baby-friendly areas). The anxiety, depression, maternal satisfaction and nurses' correct implementation rate of the best evidence were compared before and after the application of evidence.Results:After the use of evidence-based intervention, the implementation rate of nurses was above 80%. The anxiety score of parturient decreased from 55.29±10.11 to 41.74±10.35, the difference was statistically significant ( t value was 8.55, P<0.001), and the depression score decreased from 57.77 ±8.32 to 47.86 ±9.33, the difference was statistically significant ( t value was 7.23, P<0.001). Maternal satisfaction increased from 92.68% (76/82) to 98.82% (84/85), the difference was statistically significant ( χ2 value was 3.92, P< 0.05). Conclusion:The result of practice shows that through evidence-based nursing intervention, we can further standardize the postpartum optimal nursing paradigm of elderly second-child parturients in China. Reduce postpartum anxiety and depression and improve maternal satisfaction. And quality review still needs to be continuously promoted and implemented in clinical practice in order to continuously improve the quality of nursing and ensure sustainability.

OBJECTIVE: To observe cardiac ultrastructure and the expression of heat shock protein 70 (HSP70) and hypoxia inducible factor-lα (HIF-lα) in electric shock death rats and to explore the application of these indexes as the basis of medical identification in electric shock death. METHODS: Seventy-two SD rats were randomly divided into electric shock death group, postmortem electric shock group and the control group. The changes of myocardial ultrastructure were observed by transmission electron microscope, and the expressions of myocardial HSP70 and HIF-1α were observed by immunohistochemical technology. RESULTS: Myocardial myofibril fracture, mitochondrial cristae and membrane dissolution, and disordered arrangement of Z lines and M lines were observed in electric shock rats. HSP70 and HIF-lα were strong positive expressions in the electric shock death group, significantly compared with the control and postmortem electric shock groups (P < 0.05). CONCLUSION The expressions of HSP70 and HIF-lα were obviously increased in electric shock death group, which may be used as the diagnostic indicator of electric shock death.
