Objective To investigate the safety, feasibility and clinical application effect of upper arm totally implantable venous access port (TIVAP) inserted by the combination of oncologists and nurses in patients with tumor. Methods A total of 34 patients, who needed long-term transfusion treatment, were included in this study with upper arm TIVAP from March 2017 and December 2017. There were 20 males and 14 females. The median age was 63 (35~83) years. Upper arm TIVAP was implanted by both doctors and nurses into the patients with tumor, and the TIVAP related success rate, complications and patients satisfaction were recorded. Results 34 patients all succeeded in TIVAP implantation with the operation success rate of 100%. The average operation time was about 40 minutes (30 to 60 minutes) from the disinfecting cloth to the end of the suture. The operations of all patients were successful. After the operation two patients died of cancer progression, one patient had soft tissue infection around capsular bag, None of the patients had other complications such as blocked infusion, catheter shift, port reversal, and so on, and the incidence of complication was 2.94%(1/34). Conclusions Upper arm TIVAP has the advantages of safe puncture, shorter operation time, few intra-operative and post-operative complications and higher feasibility for operation by both oncologist and nurse, which can supplement the limitations and deficiencies of the chest wall port and PICC in a certain extent, therefore is a good choice for clinical application.

Objective To investigate maternal zinc metabolism and the changes of zinc-related factors as metallothionein-1(MT1) and zinc transporter-1(ZnT1) in certain types of congenital heart diseases (CHD). Methods Fifteen infants with interventricular septal defect, 12 infants with atrial septal defect and 7 infants with tetralogy of Fallot, together with their mothers were enrolled, and normal infants and their mothers were enrolled by a ratio of 1∶1 with the above three types of CHD diseases. General conditions of the mothers, along with their diets and zinc-containing drug supplementation during the pregnancy, were surveyed. Maternal blood zinc levels and serum alkaline phosphatase activities at gestation week 32 and delivery or induced abortion, and the protein and mRNA expressions of MT1 and ZnT1 in maternal serum and placental tissue at delivery or induced abortion were assayed. Results The general conditions were comparable between the CHD group and control group. The ratio of the mothers taking more zinc-rich food was significantly lower in the CHD group than in the control group. Circulating zinc levels in interventricular septal defect (73.55±5.79 μmol/L), atrial septal defect (72.66±5.82 μmol/L) and tetralogy of Fallot (68.72±6.72 μmol/L) groups were significantly lower than those in the control groups (82.77±7.88, 84.58±7.55 and 85.66±7.30 μmol/L) at delivery (P all <0.05). Similar change patterns were seen for serum alkaline phosphatase activities. The relative quantities of serum MT1 and ZnT1 proteins in interventricular septal defect (73.22±36.54 and 68.55±27.82), atrial septal defect (64.29±38.26 and 74.55±29.67) and tetralogy of Fallot (67.88±30.50 and 70.13±29.65) groups were significantly lower than those in their corresponding control groups (166.31±67.43 and 97.67±30.22, 182.56±71.40 and 111.65±32.70, and 173.81±62.36 and 108.27±28.52, P<0.01 or P<0.05). The relative quantities of placental MT1 and ZnT1 proteins and mRNA expressions in interventricular septal defect (protein quantities 0.438±0.096 and 0.384±0.061, mRNA expressions 1.23±0.82 and 0.96±0.39), atrial septal defect (0.427±0.093 and 0.377±0.059, 1.17±0.70 and 0.85±0.40) and tetralogy of Fallot (0.414±0.111 and 0.336±0.066, 1.31±0.97 and 0.90±0.38) groups were significantly lower than those in their corresponding control groups (protein quantities 0.565±0.083 and 0.541±0.090, mRNA expressions 2.78±1.06 and 1.67±0.33; protein quantities 0.622±0.136 and 0.493±0.079, mRNA expressions 2.85±0.89 and 1.72±0.38; protein quantities 0.637±0.125 and 0.521±0.089, mRNA expressions 3.21±0.99 and 1.61±0.29; P<0.01 or P<0.05). Conclusion Mothers with their fetus of certain types of CHD are found zinc deficiency, and down-regulation of MT1 and ZnT1 expressions in the serum and placenta may involve in the pathogenesis of CHD when maternal zinc deficiency.

Objective To systemically analyze the efficacy and safety of multi-oil fat emulsion injection (SMOF) in the premature infant parenteral nutrition support. Methods Databases including EMbase, PubMed, Cochrane Library, CNKI, VIP and Wanfang, were searched from libraries establishment to November 2017 for randomized controlled trials (RCTs) focusing on the efficacy and safety of SMOF in the premature infant parenteral nutrition support. All the literatures were retrieved and screened according to inclusion and exclusion criteria by two researchers. The software RevMan 5.3 was used for meta-analysis after the evaluation of methodology of quality. Results A total of 7 articles including 7 RCTs were enrolled. Meta-analysis showed that there were no significant differences in body length (OR=-0.25, 95% CI=-1.80-1.30, P=0.75), weight(OR=-0.12, 95% CI=-0.20-0.04, P=0.14), head circumference(OR=0.07, 95% CI=-0.83-0.96, P=0.88), low-density lipoprotein, high-density lipoprotein, direct bilirubin, serum creatinine(OR=-0.16, 95% CI=-0.59-0.26, P=0.45) between the infants receiving SMOF or Intralipid. But compared with the infants receiving Intralipid, hemoglobin(OR=-0.75, 95% CI=-1.49-0.00, P=0.05), red blood cells(OR=-0.23, 95% CI=-0.45-0.00, P=0.05) decreased in the infants receiving SMOF, and white blood cells(OR=1.91, 95% CI=0.46-3.37, P=0.01) increased. Conclusions SMOF can control the hemoglobin content in serum, reduce the risk and degree of jaundice in premature infant, with better safety.

Objective To investigate the effects and mechanisms of Glutamine(Gln) supplementation on neurobehavioral outcome, neuronal apoptosis, microglia polarization, and neuroinflammatory response after traumatic brain injury (TBI) in rats. Methods TBI animal models were established using Feeney's method. Sixty Wistar rats were randomly divided into three groups: control group (Con), traumatic brain injury group (TBI), and glutamine supplementation group (TBI+ Gln). We measured rat behavioral outcomes by modified neurologic severity score (mNSS) tests at day 1, 3, 7 and 14 after TBI. Apoptotic neurons were determined by Nissl staining. The microglia polarization relatived protein (Iba-1, CD16, CD86) expressions in TBI cerebral cortices were determined by immunohistochemistry staining and western blotting, respectively. While, the serum levels of tumor necrosis factor-α(TNF-α), interleukin (IL)-1 and interferon (IFN)-γ were tested by enzyme linked immunosorbent Assay (ELISA). Results Compared with the Con group, the levels of neurobehavioral outcome, neurons apoptosis, microglia polarization and neuroinflammatory factors were significantly increased in the other two groups(P=0.00). Compared with the TBl group, glutamin supplementation improved neurobehavioral outcome[7 d: (10.74±0.25)points vs. (8.94±0.24) points, P=0.01; 14 d: (8.77±0.16)points vs. (7.43±0.13)points, P=0.03]. Meanwhile, glutamin supplementation suppressed the apoptotic rates of neurons [3 d: (80.18±8.38)% vs.(65.47±7.02)%, P=0.01; 7 d: (58.90±6.12)% vs.(42.73±4.88)%, P=0.01; 14 d: (39.56±2.95)% vs.(31.12±3.16)%, P=0.01], inhibited protein expressions of Iba-1 and CD16, and increased the protein expression of CD86, which promoted the phenotypic shift of microglia from M1 to M2 phenotype, inhibited microglial activation, and thus reduced TBI-induced neuroinflammatory factors [TNF-α: (125.42±12.81)pg/ml vs. (74.36±9.25)pg/ml, P=0.01; IL-1: (69.04±8.48)pg/ml vs. (34.73±3.92)pg/ml, P=0.01; TNF-α: (89.75±9.40)pg/ml vs. (45.62±6.64)pg/ml, P=0.02]. Conclusion Glutamine supplementation can markedly reduce neuron apoptosis and improve neurological outcomes after TBI, possibly mediated by promoting the phenotypic shift of microglia from M1 to M2 phenotype and thus reducing TBI-induced neuroinflammatory factors.

Objective To observe the effects of maternal high fat diet (MHFD) during pregnancy and lactation on intestinal barrier function in offspring mice. Methods C57BL/6 pregnant mice were divided into high fat diet (MHFD) group and normal diet group (MND) randomly and were given high fat diet and normal diet during pregnancy (3 weeks) and lactation (3 weeks) respectively. Both groups of offspring mice were naturally given and bodyweight of pups was monitored at birth and weekly. After weaning, the intestinal permeability of offspring mice was detected by fluorescein isothiocyanate conjugated-dextran method (FITC-D). Immunofluorescence was used to detect the expression of ZO-1 in intestinal tissues. HE staining was used to assess the villus length and crypt depth. The intestinal cell proliferation(expression of Ki-67)and Mucin 2(MUC2) were assessed by immunohistochemistry. PAS staining was used to evaluate the goblet cells. The expression of inflammatory cytokines including IL-1β, IL-6, and TNF-α in intestinal tissue were measured by real-time PCR. Results At the age of 2 and 3 weeks, the offspring in MHFD group were significantly heavier than those in MND group. HE staining showed no obvious microscopic inflammation in both groups of 3 weeks old offspring mice, however, the relative expression levels of IL-1β (1.95±0.53 vs. 1.13±0.15; t=3.65, P=0.005), IL-6(1.40±0.71 vs. 0.73±0.17; t=2.72, P=0.04), and TNF-α(1.63±0.53 vs. 1.04±0.12; t=2.64, P=0.02) mRNA were significantly higher in the MHFD group. Compared with the 3 weeks old offspring mice in MND group, MHFD significantly increased the permeability of intestine and decreased the expression of ZO-1 in membrane. The number of Ki-67 positive cells (18.00±4.74 vs. 24.60±4.17; t=3.31, P=0.004) in each villus, goblet cells (14.70±2.91 vs. 28.10±4.95; t=7.38, P<0.001) and MUC2 positive cells (20.60±3.13 vs. 30.00±3.33; t=6.50, P<0.001) in each crypt were significantly lower than those in MND group. Conclusion Maternal high fat diet in early life of offspring mice can induce intestinal low grade inflammation and lead to the disruption of intestinal mucosal barrier in offspring mice, which may be involved in the progeny diseases.

Objective To assess the value of bedside gastrointestinal ultrasound combined with gas-water alternate injection on nasointestinal tube positioning in critically ill patients. Methods A total of 62 critically ill patients requiring post-pyloric enteral nutrition admitted to the intensive care unit in our Hospital from May 1, 2017 to December 1, 2017 were enrolled. Nasointestinal tubes were blindly inserted in a bedside setting. Then, we evaluated the nasointestinal tube position using both an ultrasound with gas-water alternate injection and the traditional auscultation method after gas perfusion. Abdominal X-ray imaging was also performed in all cases as the gold standard, and the sensitivities, specificities, positive predictive values, negative predictive values, and accuracies of the tested methods were obtained. Results Sixty-two patients were confirmed by X-ray, wherein 55 were successfully catheterized and 7 were ectopic. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of ultrasound-assisted gas-water injection were 90.9%, 100%, 100%, 58.3%, and 91.9%, respectively, which were all higher than those of traditional gas perfusion auscultation (P<0.05). Conclusion The bedside gastrointestinal ultrasound with gas-water alternate injections for nasointestinal tube positioning in critically ill patients has a certain clinical value.

Objective To investigate the efficacy and safety of nasogastric feeding tube placed by endoscopy to give enteral nutrient solution in the pediatric intensive diseases. Methods A retrospective analysis of 30 children with serious illness who were given enteral nutrient solution through the nasogastric feeding tube placed by endoscopy from January 2013 to May 2016 in our hospital was conducted including 12 boys and 18 girls aging from 2 months to 14 years with the mean as (6.86±3.44) years old. Catheterization condition including catheter insertion time after hospitalization, catheter maintenance time, hospital stay and retention time after discharge, postoperative complications after catheterization, prognostic indications including anal exhaust and defecation time, blood urine amylase and returning to normal time, and changes of the indicators for nutrition including total protein, albumin, prealbumin, retinol binding protein were analyzed. Results Catheter insertion time after hospitalization was (16.13±10.51) days, catheter maintenance time (21.35±9.62) days, hospitalization time after catheterization (20.10±8.96) days and hospital stay (36.23±14.20) days. 10 cases (33.3%) maintained the catheter for (11.10±4.65) days after the discharge. The anal exhaust time was (2.84±3.32) days and the defecation time (4.55±3.35) days; The urinary amylase significantly deceased three days after catheterization compared with that of one day before catheterization (P=0.047); Serum total protein, albumin, prealbumin and retinol binding protein increased three days after catheterization compared with that of one day before catheterization, but the difference was not statistically significant (P>0.05). 5 children (17%) had complications including 3 children of abdominal distension and 2 children of vomiting. Conclusions Nasogastric feeding tube placed by endoscopy to give enteral nutrient solution in the pediatric intensive diseases can improve the intestinal and pancreatic function, recover their nutritional status to some extent and be controlled safely. However, the waiting time for catheterization and the hospital stay after catheterization are relatively long.

Objective To investigate the effects and mechanism of (-)-epigallocatechin-3-gallate (EGCG) on white adipose tissue angiogenesis in high fat diet rats. Methods Twenty-four male weaning SD rats were randomly divided into normal control group, high fat diet group and EGCG intervention group, 8 rats in each group. Normal control group were fed with normal diet, high-fat diet group were fed with high-fat diet, EGCG intervention group were fed with high-fat diet along with intragastric administration of 200 mg/(kg·d) EGCG. After 8 weeks, the rats were sacrificed. The adipocyte size and vascular density of the abdominal adipose tissue in rats in each group were observed under the microscope.The serum vascular endothelial growth factor (VEGF) concentration was detected by Elisa Kit. RT-PCR was used to detect the expression of VEGF, nuclear factor E2 (Nrf2), heme oxygenase-1 (HO-1), catalase (CAT), SOD, GPx, interleukin-6(IL-6) and monocyte chemoattractant protein-1 (MCP-1) mRNA. Results The adipocyte size, number of vascular/each adipocyte, serum VEGF concentration and VEGF mRNA expression in adipose tissue of high fat diet group were significantly higher than those of normal control group (all P<0.05). EGCG can significantly reduce the above indicators of high fat diet group (all P<0.05). The expression of Nrf2, HO-1, SOD, GPx and CAT mRNA in adipose tissue of EGCG group was significantly higher than those in high fat diet group and normal control group (all P<0.05). The expression of MCP-1 and IL-6 mRNA in adipose tissue of EGCG group was significantly lower than that in high fat diet group (all P<0.05). Conclusion EGCG can decrease the production of serum VEGF, vascular density and the expression of VEGF mRNA in white adipose tissue of high fat diet rats, and inhibit the angiogenesis in white adipose tissue possibly due to its up-regulation of Nrf2/HO-1 pathway to increase the expression of antioxidant enzymes (SOD, CAT, GPx), reduce ROS production and decrease the inflammatory response.

The expression of MCP-1 and IL-6 mRNA in adipose tissue of EGCG group was significantly lower than that in high fat diet group (all P<0.05). \u0000 \u0000 \u0000Conclusion \u0000EGCG can decrease the production of serum VEGF, vascular density and the expression of VEGF mRNA in white adipose tissue of high fat diet rats, and inhibit the angiogenesis in white adipose tissue possibly due to its up-regulation of Nrf2/HO-1 pathway to increase the expression of antioxidant enzymes (SOD, CAT, GPx), reduce ROS production and decrease the inflammatory response. \u0000 \u0000 \u0000Key words: \u0000(-)-Epigallocatechin-3-gallate; High fat diet; White adipose tissue; Angiogenesis; Vascular endothelial growth factor","PeriodicalId":9877,"journal":{"name":"Chinese Journal of Clinical Nutrition","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47628320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
