Objective To summarize the experiences of extracorporeal membrane oxygenation (ECMO) technique in human lung transplantation. MethodsECMO was used in 45 patients undergoing lung transplantation.There were 32 cases of dilated pulmonary fibrosis and pulmonary hypertension,4 cases of chronic obstructive pulmonary disease,2 cases of pneumosilicosis,2 cases of phthisis,one case of diffuse panbronchiolitis,2 cases of bronchiectasis and 2 cases of primary pulmonary hypertension. In 3 patients, ECMO conduit was used as a bridge to the lung transplantation for 13,19 and 6 days respectively before operation,and ECMO support was done after the operation.In 40 patients ECMO support was done during operation.In 2 patients without using cardiopulmonary bypass, ECMO support was done after operation because of primary graft dysfunction.Results In 40 patients undergoing ECMO support during operation,the ECMO conduit was removed in 37 patients immediately after the operation.ECMO mean blood flow was (2.8 ± 0.6)L/min,running time was (7.7 ± 0.9) h,and 31 patients survived. In 3 patients undergoing postoperative ECMO support,ECMO was removed in 2 cases at 36th h and 6th day after the operation respectively,and the remaining one died from acute renal failure 2 weeks after the operation though the continuing hemofiltration was applied through ECMO conduit. In 2 patients without using cardiopulmonary bypass and 3 patients using ECMO during operation,ECMO support was used initially or again after operation because of PGD or acute heart failure.Three patients were cured,and 2 patients were died from multiple system organ failure.Conclusion ECMO is an important auxiliary tool in lung transplantation for preoperative,intraoperative and postoperative supports. As the transition bridge to recipients,ECMO can be used for preoperative supports; during operation,it can stabilize the haemodynamics,and postoperation,it can improve severe pulmonary function dysfunction and PGD.

Objective To explore the relationship between plasma homocysteine levels and diabetic retinopathy (DR).MethodIn 40 DR patients and 63 non-DR patients,the indexes including plasma homocysteine concentrations,duration of diabetes,ages,blood pressure,preprandial blood glucose(PBG),plasma GHbA,e,plasma lipids,serum folie acid and semm vitamin B12 were analyzed.ResultsPlasma homocysteine level was significantly higher in DR patients (12.9μmol/L) than that in non-DR patients (7.8μ.mol/L) (P＜0.01),and the relationship remained significant correlation after adjusted for duration of diabetes,GHbA1c,ages,serum folic acid and serum vitamin B12(OR = 1.23,P＜0.05).ConclusionHyperhomocysteinimia is a risk factor and an independent predieator of DR.

Objective To study the effect of early enteral nutrition (EEN) with ω-3 polyunsaturated fatty acid on nutritional status and body immunity of postoperative patients with colorectal cancer.Methods Forty patients with colorectal cancer were randomly divided into EEN group and parenteral nutrition (PN) group by systematic sampling method with 20 cases of each.The patients in EEN group were given complete enteral nutrition with ω-3 polyunsaturated fatty acid 1-7 d after operation,while the patients in PN group only were given nutrient by regular PN.Nutritional status,body immunity before operation and 1-7 d after operation,and intestinal function recovery time,untoward reaction were determined.Results The postoperative anus first exhaust time and defecate time of patients in EEN group were significantly shorter than those in PN group [(48.0±5.6) hvs.(51.0±6.7) h,(53.0±4.8) h vs.(72.0±3.6) h,P＜0.05].Serum albumin and prealbumin 1 d after operation in 2 groups were significantly lower than before operation (P ＜0.05),but 7 d after operation were significantly higher than 1 d after operation (P ＜0.05).Serum albumin and prealbumin 7 d after operation in EEN group were significantly higher than PN group(P ＜ 0.05).IgG,IgA,IgM,CD3,CD4,CD8,CD4/CD8 1 d after operation in 2 groups were significantly lower than before operation (P ＜ 0.05).IgG,IgA,CD4,CD4/CD8 7 d after operation in EEN group were significantly higher than PN group (P＜ 0.05).Conclusions Compared with the PN,EEN with ω-3 polyunsaturated fatty acid can remarkably improve nutritional status and body immunity in postoperative patients with colorectal cancer.It can accelerate the recovery of intestine function and worthy of recommending.

AIM: To investigate the effect of nucleolin on diabetic cardiomyopathy in mice.METHODS: A type II diabetic cardiomyopathy mouse model was prepared using a cardiac-specific nucleolin-overexpressing transgenic mice.The mice were divided into wild-type mouse control group, nucleolin transgenic mouse control group, wild-type mouse diabetes group and nucleolin transgenic mouse diabetes group.Wheat germ agglutinin (WGA) fluorescent dye, Masson staining and PowerLab system detection were used to further clarify the role of nucleolin on cardiac hypertrophy, fibrosis and cardiac function in type II diabetic cardiomyopathy mice.RESULTS: Compared with wild-type mouse control group, no significant increase in blood glucose level was found, while genetical myocardial cell hypertrophy was significantly attenuated in nucleolin transgenic mouse diabetes group.The collagen fibers were also significantly reduced, and hemodynamic indexes ± dp/dtmax, left ventricular end-diastolic pressure, left ventricular systolic pressure and heart rate were also improved.The above differences were statistically significant.CONCLUSION: Nucleolin may reduce the occurrence of myocardial hypertrophy and fibrosis, thus improving the cardiac function of diabetic cardiomyopathy mice.

Objective To explore the effects of pretreatment of bone marrow mesenchymal stem cells (BMSCs) by ultrasound-exposed microbubbles (UM) on both homing to ischemic myocardium and cardiac function after acute myocardial infarction (AMI).Methods Rats of AMI model established by ligation of left anterior descending coronary artery were divided into four groups randomized:phospho-buffered saline (PBS) group,stem cells treatment (SCT) group,ultrasound and stem cells treatment (USCT) group,and UM stem cells treatment (UMSCT) group,and each group was injected with PBS,stem cells,US-pretreated stem cells and UM-pretreated stem cells through the caudal veins after AMI respectively.Homing of BMSCs to the ischemic myocardium was examined by confocal microscopy at 48 h after implantation,and cardiac function was examined by ultrasonic cardiogram (UCG) after 4 weeks.Masson staining was used to examine the changes of local ischemic cardiac tissues,and immunohistochemistry was used to detect the density of local neo-capillaries (CD31).Results 1) The numbers of CM-Dil-positive cells counted under confocal microscopy in the ischemic myocardial tissues of each groups 48 hours after implantation were not the same:there was no significant difference of the numbers of positive cells between USCT group (19.67 ±2.08) and SCT group (18.67 ± 2.08).However,the number of positive cells in the UMSCT group (39.33 ±3.06) was larger than that in USCT group and SCT group (P ＜0.05).2) UCG examinations showed that there was no significant difference of left ventricular systole function between the USCT group [LVEF (44.92 ± 2.77)％,LVFS (22.83 ± 1.79)％] and SCT group [LVEF (42.28 ± 2.82)％,LVFS (21.52 ±1.88) ％,P ＞0.05],but both were better than that in PBS group [LVEF (20.52 ± 1.88)％,LVFS (9.55 ±0.85) ％,P ＜0.05].The left ventricular systolic function in UMSCT group [LVEF (61.85 ± 3.15)％,LVFS (32.74± 2.45)％] was significantly higher than that in USCT group and SCT group (P ＜0.05),while which was still significantly lower than that in pseudo-surgery group [LVEF (75.88± 4.52)％,LVFS (42.76 ± 2.88)％,P ＜0.05].3) Pathological examinations showed the percentages of AMI areas in the USCT group (35.9 ± 1.1％) were not different compared with that in SCT group [(36.5 ± 1.3)％,P ＞0.05],while both were significantly smaller than that in PBS group [(45.2± 1.4)％,P ＜0.05].The percentages of AMI areas in the UMSCT group [(25.8 ± 1.0)％] were significantly smaller than that in USCT group and SCT group (P ＜0.05).The density of neo-capillaries (25.9 ± 1.3) in USCT groups had no difference compared with that in SCT group (25.2 ± 1.3),while both were significantly higher than that in PBS group (17.6 ± 1.1,P ＜0.05);the density of neo-capillaries (33.2 ± 1.6) was significantly higher in UMSCT group than that in both USCT group and SCT group (P ＜0.05),which were examined by immunohistochemistry.Conclusions Homing to ischemic myocardium of BMSCs transplanted intravenously could be promoted by UM pretreatment,which stimulates development of capillaries,reduces AMI areas,and improves the cardiac function after AMI.
