BACKGROUND: Adipose-derived stem cells (ADSCs) represent one of the promising cell sources for myocardial regeneration due to their easy accessibility and efficacy in the improvement of cardiac function following myocardial infarction. However, previously reported studies on the underlying mechanism of ADSCs-mediated cardioprotective effect mainly focused on the ADSCs cultured at room air. OBJECTIVE: To test the paracrine actions and anti-apoptotic effect of ADSCs under hypoxic conditions. METHODS: After isolation and culture, neonatal rat myocardial cells were injured by hydrogen peroxide and co-cultured with rat ADSCs under normoxia and hypoxia (10% O2) conditions. Ratio of reduced glutathione to oxidized glutathione (GSH/GSSG) in the cell pellet and levels of vascular endothelial growth factor (VEGF), insulin-like growth factor 1 (IGF-1), and basic fibroblast growth factor (bFGF) were tested by ELISA. Expression of apoptotic proteins Bax and Bcl-2 were determined by western blot. RESULTS AND CONCLUSION: GSH/GSSG, VEGF, IGF-1, and bFGF were decreased in neonatal rat myocardial cells injured by hydrogen peroxide. ADSCs significantly attenuated hydrogen peroxide-induced myocardial apoptosis by increasing the ratio of GSH/GSSG and the secretion of VEGF, IGF-1 and bFGF. ADSCs also down-regulated Bax expression and up-regulated Bcl-2 expression. To conclude, hypoxic conditions can enhance the anti-apoptosis and cardioprotective effects of ADSCs through the paracrine mechanism.

Objective To analysis the clinical effects of biliary-pancreatic double stents in pancreatic cancer patients with obstructive jaundice.Methods From July 2008 to October 2011,a total of 60 patients with advanced pancreatic cancer were randomly divided into two groups to receive biliary-pancreatic double stents (n =28) or biliary stent only (n =32) according to the odd and even numbers of their admission date.Changes in liver function,abdominal pain,quality of life scores (QOL) were compared between two groups.Results The stents were placed successfully in 54 patients (90.0％),in which symptoms were relieved or gradually disappeared in all patients after the procedure.One week after stents placement,the serum total bilirubin decreased significantly from 164.32 ±45.16 μmol/L before ERCP to 63.25 ±27.06 μmol/L (P ＜ 0.05),other parameters including ALT,AST,AKP and r-GT were also decreased significantly compared with those of pre-ERCP (P ＜ 0.01),but there was no significant difference between the two groups (P ＞ 0.05).25 cases in double-stents group and 29 cases in single-stent group had varying degrees of pain relief at 7d after ERCP,but the overall pain relief rate and complete pain relief rate in double-stent group were significantly higher than those in single-stent group (92.0％ vs.55.2％; 64.0％ vs.34.5％,P＜0.05).At 7d and 14d after ERCP,Karnofsky QOL score were improved significantly in double-stent group (P ＜ 0.05).It was significantly better than single-stent group at 14d after ERCP (P ＜0.05).No death or other severe ERCP-related complications were observed.Conclusion Biliary-pancreatic stent placement for pancreatic cancer could significantly improve liver function and relieve obstructive pain.In the ways of alleviating pain and improving quality of life scores,it was better than ERCP biliary stent placement,especially for patients with pancreatic cancer combined obstructive pain.It indicated that biliary-pancreatic stent placement was better than simple biliary stent placement for advanced pancreatic head cancer patients with obstructive pain.

Objective To explore the characteristics of dipyridamole 201 Tl myocardial perfusion imaging (MPI) SPECT in patients with dilated cardiomyopathy. Methods Thirty patients with dilated cardiomyopathy underwent pharmacological stress 201Tl MPI SPECT after intravenous infusion of dipyridamole (0. 56 mg/kg) for 4 min. The early and delayed SPECT images were acquired respectively at 10 and 240 min after 201Tl injection. The images were analyzed and reported by two or three experienced nuclear medicine physicians. Results All patients were found to have abnormal perfusion patterns at delay imaging, however 90.00% (27/30) were also abnormal at early images. Six patients had reverse redistribution. Conclusion Dipyridamole 201Tl MPI SPECT imaging may be of some value for the assessment of patients with dilated cardiomyopathy.

Objective To investigate the clinical effect of pulmonary rehabilitation therapy including respiratory exercise and vibration expectoration on patients with pulmonary infection after abdominal surgery.Methods A retrospective case control study was conducted.Seventy-six patients with pulmonary infection after abdominal surgery admitted to the First Affiliated Hospital of Hunan Normal University from September 2015 to September 2016 were enrolled.According to whether accept the pulmonary rehabilitation therapy or not,the patients were divided into two groups.In the control group (n =35),the convemional expectoration method was adopted.The patients in pulmonary rehabilitation group (n =41) received both methods of the control group and pulmonary rehabilitation treatment,including respiratory exercise (effective cough,lip reduction breathing),respiratory exercise device (respiratory exerciser tri-ball),and vibrated expectoration.The 24-hour sputum volume,degree of comfort,inflammatory and pulmonary function parameters,and recovery situation were recorded in the two groups.Results ① There were no significant differences in the parameters of inflammation and pulmonary function before treatment between the two groups.After treatment,the white blood cell (WBC) and C-reactive protein (CRP) in both groups were significantly decreased,and the forced expiratory volume in 1 second (FEV1) and FEV1/forced vital capacity (FVC) were significantly increased.The above changes in pulmonary rehabilitation group were more significant than those of the control group [WBC (× 109/L):11.12 ± 2.88 vs.13.42 ± 2.62 at 3 days,8.22 ± 1.48 vs.9.27 ± 1.92 at 5 days;CRP (mg/L):13.47 ± 4.77vs.16.03±4.94 at 3 days,9.69±1.56 vs.11.77±1.41 at 5 days;FEV1 (L):2.48±0.14 vs.2.29±0.16 at 3 days,FEV1/FVC:0.78±0.04 vs.0.75±0.04 at 3 days;all P ＜ 0.05].② The 24-hour sputum volume within 3 days of pulmonary rehabilitation group were significantly higher than that of the control group (mL:30.51 ± 4.15 vs.18.30 ± 3.64at 1 day,31.08±3.22 vs.20.37±3.20 at 2 days,29.03±2.55 vs.19.03±2.51 at 3 days,all P ＜ 0.01].③ In the pulmonary rehabilitation group,the recovery time of pulmonary infection symptoms (days:5.44 ± 1.45 vs.6.20 ± 1.55),the days of antibiotic use (days:12.61 ± 3.15 vs.15.03 ± 3.78),the time of getting out of the bed (days:4.05 ± 0.74vs.4.51±0.89),and the hospital days (days:19.95±3.90 vs.22.00±4.42) were significantly shorter than those of the control group (all P ＜ 0.05),and the degree of comfort was significantly better than that of the control group (comfort score:2.71 ±0.90 vs.2.14±0.91,P ＜ 0.01).Conclusion The application of pulmonary rehabilitation including respiratory exercise and vibration expectoration in abdominal surgery patients with pulmonary infection can promote recovery,and it has a good clinical and practical application value.

Objective To analyze the clinical features and prognosis of patients with infective endocarditis(IE) and acute kidney injury(AKI),and to evaluate the effect of timely operation on prognosis of renal function.MethodsClinical data of 45 IE and AKI cases in Peking Union Medical College Hospital from January 2010 to May 2016 were retrospectively reviewed;among them 8 cases underwent renal biopsy and the pathologies were analyzed.Patients were divided into Operation group(22 cases) and Non-operation group(23 cases),the clinical data and prognosis were compared.Results The ratio of male to female was 2.46:1 and the average age was 48.3±16.6.35.6% of cases were found with basic valve diseases,the congenital valve diseases were the most common type.The most frequently infected valves were mitral valve(46.7%),aortic valve(28.9%) and prosthetic valve(8.9%) ordinally.The most common pathogenic bacteria were streptococcus(46.7%) and staphylococcus(35.6%).Some rare and special pathogen could also be found in these cases.In 8 cases underwent renal biopsy,3 cases were diagnosed as crescentic nephritis,2 cases were diagnosed as focal proliferative glomerulone-phritis and mesangial prolif-erative glomerulonephritis respectively,1 case was diagnosed as acute interstitial nephritis.C3 sedimentation was the most common phenomenon found in immunofluorescence.There was no significant difference between the baseline data of Operation and Non-operation groups,and neither was the survival rate.However,renal function recovered better in Operation group(P<0.05): the serum creatinine declined remarkably in 7 days(P<0.05) and 30 days(P<0.01)post operation,compared with the peak valve before operation.Conclusions The underline valve diseases and pathogen have been changed in IE as compared with traditional description.Crescentic nephritis is common in renal pathologic manifestation when parenchymal lesion is developed after the onset of IE.Timely operation can improve the renal prognosis in patients with IE and AKI.
