Objective To evaluate the effects of blood perfusion(HP)combined with hemodialysis(HD)on micro inflammation and malnutrition status in patients with maintenance of hemodialysis(MHD). Methods Eighty MHD patients admitted to blood purification center of Wuhan Puai Hospital in Hubei Province were enrolled and randomly divided into two groups. Pure HD group underwent conventional HD for 4 hours,3 times a week,and based on the weekly HD series,the HD+HP group took additionally HP once a week,the therapeutic course in both groups being consecutive 12 weeks. Blood was collected before and after treatment for detection of interleukin-6. (IL-6) and tumor necrosis factor-α(TNF-α) levels by enzyme-linked immunosorbent assay (ELISA), and the serum high sensitivity C-reactive protein (hs-CRP) and homocysteine (Hcy) levels were determined with electrochemiluminescence immunoassay,and the changes in nutritional indexes of hemoglobin(Hb),total protein(TP), albumin(Alb),transferrin(TRF)were observed. Results Compared with the indexes before treatment,in HD+HP group,hs-CRP(ng/L:5.65±2.21 vs. 13.91±2.10),IL-6(ng/L:50.10±6.65 vs. 101.22±21.32),TNF-α(ng/L:80.21±9.41 vs. 197.64±25.47),Hcy(μmol/L:13.31±2.21 vs. 40.96±9.42)were significantly decreased (all P<0.05),and Hb(g/L:106.65±22.21 vs. 92.01±12.10),TP(g/L:62.10±22.65 vs. 51.22±11.32),Alb (g/L:38.21±6.41 vs. 30.84±5.47),TRF(μg/L:196.31±22.21 vs. 161.96±15.42)were significantly increased (all P<0.05);but the above parameters in HD group did not change significantly(all P>0.05). There were statistical significant differences in above indexes after treatment between HD+HP group and HD group〔hs-CRP (ng/L):5.65±2.21 vs. 13.22±1.10,IL-6(ng/L):50.10±6.65 vs. 100.32±25.24,TNF-α(ng/L):80.21±9.41 vs. 196.87±24.54,Hcy(μmol/L):13.31±2.21 vs. 37.23±8.33,Hb(g/L):106.65±22.21 vs. 94.22±13.10,TP (g/L):62.10±22.65 vs. 51.32±12.32,Alb(g/L):38.21±6.41 vs. 32.87±4.54,TRF(μg/L):196.31±22.21 vs. 162.23±15.33,all P<0.05〕.

Autophagy is a degradation process of intracellular composition.It can be divided into four different stages,including initiation,elongation,maturation and autophagosome breakdown.Its role is associated with the degree of cell damage.Moderate activation of autophagy in the case of starvation and hypoxia can promote cell survival; whereas excessive activation during cerebral ischemia can cause cell lysis and promote cell death.Preconditioning may produce ischemic tolerance by appropriate activation of autophagy.Autophagy is strictly regulated by a variety of protein kinases,apoptotic molecules and oxidative stress pathways.

ATP-sensitive potassium channel congenital hyperinsulinism (KATP-HI) is the most common and most severe type of congenital hyperinsulinism,accounting for 40％-45％.It is due to the inactivating mutations of the ABCC8 and KCNJ11 gene which encode the ATP-sensitive potassium channel.Diazoxide is the main and preferred therapy for KATP-HI.For KATP-HI children who are unresponsive to medical therapy usually need different degrees of pancreatectomy to maintain normal blood sugar level.

Objective To investigate the correlations between plasma indoxyl sulfate and p-cresyl sulfate in the pathogenesis of cardiovascular complications in maintenance hemodialysispatients.Methods A total of 145 maintenance hemodialysis patients were selected.The researchers measured the physiological parameters of the subjects,including pre albumin,albumin,hemoglobin,blood urea nitrogen,creatinine,uric acid,calcium,phosphorus,alkaline phosphatase,total cholesterol,triglyceride,low-density lipoprotein cholesterol,high-density fat cholesterol,intact parathyroid hormone,C-reactive protein,apolipoprotein,lipoprotein,homocysteine,beta 2-microglobulin,sulfuric acid indoxyl,sulfuric acid cresol,serum iron,transferrin,ferritin,and N-terminal pro brain natriuretic peptide carrier.Subjects underwent cardiac ultrasound examination.Results The researchers used heart structure and function as the dependent variable.The single factor Cox regression analysis showed that the risk of heart structure and function changes increased with the increase of systolic blood pressure,N-terminal B-type natriuretic peptide,and left ventricular mass index.This study also showed that the risk of heart structure and function changes in patients with previous history of coronary heart disease also increased.The researchers took the systolic blood pressure,coronary heart disease history,N-terminal brain natriuretic peptide,and the left ventricular mass index as the dependent variables.Multifactor Cox regression analysis showed that the history of coronary heart disease,the high left ventricular mass index and the change of the heart structure and function of the patients with acute coronary heart disease were the independent predictors of the change of heart structure and function.The researchers used cardiovascular complications as the dependent variable.Cox regression analysis showed that,with the increase in patient's age,dialysis duration,elevated high C-reactive protein and sulfuric acid p-cresol,patients suffering from the risk of fatal cardiovascular complications rise.The researchers used the complications of cardiovascular deaths as dependent variable,age,duration of dialysis,C-reactive protein,and sulfuric acid p-cresol as covariates,multivariate Cox regression analysis of the results showed that with increasing age,dialysis duration increased,high sulfate of cresol and C-reactive protein,patients suffering from the risk of death from cardiovascular complications rise.Conclusions The history of coronary heart disease,left ventricular mass index,systolic blood pressure,indoxyl sulfate,Nterminal brain natriuretic peptide,age,dialysis age,high C-reaction protein,and p-cresol sulfate are the independent risk factors for cardiovascular complications.The relationship between indoxyl sulfate and sulfuric acid serum concentration of p-cresol and adverse cardiovascular events is most closely.

Objective To investigate and analyze the perioperative nursing of patients with breast cancer, and explore the effectiveness of the application of mind map in perioperative nursing care of patients with breast cancer. Methods The cluster sampling method was employed, and 265 patients with breast cancer receiving radical mastectomy treatment from department of general surgery of the First Affiliated Hospital of Liaoning Medical University were gathered according to the inclusion and exclusion criteria. 137 cases were assigned to test group (May 2014 to April 2015), and 128 cases were assigned to control group (May 2013 to April 2014 ). Nursing work was improved by establishing research group, discussing the design of perioperative nursing mind map and applying mind maps. Effect was evaluated by evaluating the incidence of postoperative complications in patients with breast cancer, the quality of patient′s life and the patient′s satisfaction. Results The incidence of bleeding, seroma, flap necrosis, upper extremity swelling and other postoperative complications of patients with breast cancer in test group was 26.28%(36/128),and that in control group was 73.44%(94/137). The differences between the two groups were of statistical significance (χ2=58.891, P<0.01). The perioperative survival quality scores of physiology, society/family, emotions, function, additions and total in the test group were (2.43 ± 1.09), (2.64±0.97), (2.85±0.97), (2.43±1.09), (2.22±1.12),(2.34±1.13), and that in the control group were (1.89± 1.09), (1.89 ± 1.06), (1.78 ± 0.92), (1.89 ± 1.09), (1.76 ± 1.05), (2.00 ± 1.09)respectively. The differences between the two groups were statistically significant (t=4.664-10.829,P<0.01). The proportion of patient satisfaction in test group was 94.89%(130/137),and that in control group was 82.03%(105/128), respectively. The differences between the two groups were statistically significant (χ2=10.900, P < 0.01). Conclusions Application of mind map in nursing intervention is able to help nurses to grasp the key content and direction of perioperative nursing on patients with breast cancer. More importantly, not only can it improved patients′quality of life and reduce the incidence of postoperative complications, but also increases patients′satisfaction.

Objective To investigate the protective effect of somatostatin (SS)combined with growth hormone (GH) in treatment of intestinal mucosal barrier injury in rabbits with severe acute pancreatitis (SAP), as well as its clinical significance. Methods Seventy-two rabbits were equally assigned into model group (SAP group), SS treated group (SS group) and SS combined with GH treated group (SS + GH group). SAP models were induced by retro-injection of 5% sodium taurocholate into the pancreatic duct. After modeling, all rabbits were given 5 % glucose saline daily.The rabbits in SS group and SS+GH group were continuously Given SS (3.5μg·kg-1·h-1)for 48 hours. Besides, the rabbits in SS+GH group were subcutaneously injected with 0.15 IU/kg of GH at the 1st and the 24th hours after modeling. The levels of serum amylase, serum tumor necrosis factor-α (TNF-α) and plasma diamine oxidase were measured at the 6th, 12th, 24th and 48th hours after modeling. The pathological changes of pancreatic tissue and ileal mucosa were observed. Survival rate was calculated. Data were analyzed using SPSS 16.0 software. The univariate analysis was used to compare the difference among groups. Results In SS+GH group, the levels of serum TNF-α and plasma diamine oxidase were (2. 43 ± 0. 14) pg/ml and (4. 61 ± 0. 45) U/L at the 24th hour respectively, and were (2.08±0.23) pg/ml and (3.75±0.47) U/L at the 48th hour, respectively,which were lower than those in SAP group and SS group [(2.80 0.30) pg/ml and (8.74 ± 1.77)U/L, respectively, at the 24th hour; (2. 45±0.12) pg/ml and (5. 02±0.95) U/L, respectively, at the 48th hour)]with significant difference (P＜0.05). The inflammation in pancreas and ileal mucosa was alleviated, and the integrity of bowel mucosa was improved. Survival rate of SS+GH group was significantly higher than SAP group and SS group. There was no significant difference in level of serum amylase between SS+GH group and SS group. Conclusion The combination of SS with GH may enhance the function of intestinal mucosa barrier and improve the prognosis of SAP in rabbits.
