Objective To evaluate the timing of postoperative parenteral nutrition support for gastrointestinal tumor patients with a definite nutritional risk.Methods Using a randomized control clinical research methods,80 gastrointestinal cancer patients were randomly divided into study group (40 cases) and control group (40 cases).In the study group parenteral nutrition support started on postoperative day 2,while in the control group it started on postoperative day 1.Flatus passing,the rate of infectious complications,the rate of systemic inflammatory response syndrome,postoperative nutrition support related expenses,and the duration of postoperative hospital stay were recorded.Results There was no significant differences between the two groups (P ＞ 0.05) in age,sex,body mass index,use of glutamine,disease and type of surgery.Compared with the control group,patients in the study group had earlier postoperative flatus passing [(3.33± 1.10) d vs.(4.03 ± 1.51) d,P =0.020],less systemic inflammation response syndrome (8/40 vs.17/40,P =0.030),shorter postoperative hospital stay [(3.33±1.10) d vs.(4.03±1.51) d,P=0.020] and lower nutrition support costs [(2144.49 ±1210.96) RMB vs.(2915.99 ± 1615.68) RMB,P =0.018].There was no significant difference in postoperative nutrition index,peristalsis recovery time and infectious complications between the two groups (all P ＞ 0.05).Conclusions In patients undergoing surgery for GI tumors,parenteral nutrition support started on post-op day 2 promotes the recovery of gastrointestinal function,while decreasing medical cost.

OBJECTIVE: In recent years, in the field of neurosurgery, people have tried to study the mesenchymal stem cells(MSCs) transplantation for treatment of spinal cord injury and review its related studies.DATA SOURCES: We did a computer-search of Medline for spinal cord injury related articles published in English from January 1990 to November 2004, with the key words of "mesenchymal stem cells, transplantation,spinal cord injury". Meanwhile, We also searched Chinese Biomedical Literature Database (CBM) for bone marrow-derived mesenchymal stem cells for transplantation of spinal cord injury related articles published from January 1990 to November 2004, with the key words of "mesenchymal stem cells, transplantation, spinal cord injury" in Chinese.STUDY SELECTION: All articles were selected firstly, and those relevant to progression of mesenchymal stem cells transplantation in spinal cord injury therapy were collected. The full texts of the rest literatures were looked up and the latest evolutional articles were enrolled.DATA EXTRACTION: A total of 32 articles about the mesenchymal stem cells transplantation in spinal cord injury therapy were collected. After the exclusion of repetitive or similar studies, 19 articles met our criteria.DATA SYNTHESIS: Aiming at the spinal cord injury therapy by means of mesenchymal stem cells transplantation, the viewpoints of collected articles were summarized. We found bone marrow derived mesenchymal stem cells could supply lesioned part as filler. Directional regeneration accomplishes the construction of the function that transfers up and down for the nerve cell anchor through surrounding structure. The microenvironment which can inhibit the regeneration of the glial cell, protect the survival of nerve cell body, promote the regeneration of autogenic nerve cells shall be created in transplant. The international successful experience was introduced emphatically, and the most hopeful outlook was suggested.CONCLUSION: The transplanted MSCs survive, migrate to the injury site and differentiate into neurons and astrocytes. Transplantation of MSCs following spinal cord injury may improve the recovery of spinal function and may be an effect way in treating spinal cord injury.

Skeletal muscle is essential for the glucose disposal in organism, which is one of the major sites of insulin resistance.The over-activity of classical renin-angiotensin system ( RAS) induces the oxidative stress, leads to the impairment of insulin signaling and glucose transport, resulting in insulin resistance of skeleton muscle.The activation of non-classical RAS by inhibiting classical RAS activity, can ameliorate insulin resistance in skeletal muscle tissue.

Objective To investigate the causes of reduced function of neutrophils in neonates by measuring superoxide, one of the reactive oxygen species, produced by neutrophils following live bacterial phagocytosis in the whole blood. Methods Twenty-three cord blood samples were collected from normal full-term newborns and cultured with live Staphylococcus aureus and Escherichia coli. Blood cells were stained with Hydroethidine, an indicator of superoxide. The intensity of the superoxide of neutrophils were analyzed by flow cytometry. Fifteen adult blood samples were collected as control. Plasma replacement was used to study the function of body fluid in active oxygen metabolism of neutrophils. Results Most full-term neonatal neutrophils (PMNs) could produce superoxide anion following bacterial phagocytosis in the blood as that in adults. The level of superoxide production of term neonatal neutrophils, after stimulation of S. aureus, was as high as the adult′s but was significantly lower after stimulation by E. coli (bacteria cell ratio 40∶1, MFI 347?70 vs 461?55, P

Objective To investigate current status of learned resourcefulness in pregnant women,and to identify its influencing factors.Methods With convenient sampling,a self-made General Data Questionnaire and the Chinese version of Self-Control Schedule (C-SCS) was used to survey 360 pregnant women in the antenatal clinic in one three-class hospital in Guangzhou.Results The mean score of learned resourcefulness in pregnant women was (115.00±14.42) and its influencing factors included education degree,gravidity,pregnancy school training and planed pregnancy.Conclusions Learned resourcefulness in pregnant women loads upper level.Medical staff should take targeted interventions to strengthen it and facilitate the mental well-being of pregnant women.

Two hundred and twenty-four patients with metabolic syndrome (MS) and 200 subjects as normal controls were included in this study.Genotyping of +276G/T,+45T/G SNPs in apM1 gene was made by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique,and then the distribution and differences in genotypes and allele frequencies in the population were observed.It was found that the G/T polymorphism of +276 site was associated with MS,while +45 T/G polymorphism had nothing to do with MS.It is suggested that the +276G/T polymorphism may be a predisposing factor of MS.

Objective To explore the curative effect of ursodeoxycholi acid on retinopathy of prematurity (ROP) caused by high concentration of oxygen in newborn rats. Methods The model of ROP was established. Neonatal rats were divided into normal control group, ROP model group, low dose ursodeoxycholi acid treatment group (10mg/kg) and high dose ursodeoxycholi acid treatment group (40mg/kg). Rats were sacrificed at days 17. The new retinal vessels were observed and counted under lfuorescence microscope. Results The new retinal vessels in ROP rats were hyperplastic, twisted and unevenly distributed. There was signiifcant difference in the number of new retinal vessels among different groups (P=0.000). The number of new retinal vessels of rats in ROP group, low-dose group and high-dose group was signiifcantly more than that in control group (P=0.000). The number of new retinal vessels in low-dose group and high-dose group was significantly less than that in ROP group (P<0.05). The number of new retinal vessels in high-dose group was less than that in low-dose group (P>0.05). Conclusions Ursodeoxycholi acid could inhibit the angiogenesis of retina and could have curative effect on ROP.

Objective To analyze the risk factors associated with allergic disease in preterm infants during the first year of life. To investigate whether there was any association between peripheral blood eosinophils and allergic di-sease during the first year of life benefit of hydrolyzed formula feeding in preterm infants. Methods A nested case -control study was conducted in a cohort of artificial feeding preterm infants admitted to Neonatal Intensive Care Unit, Shanghai Children's Medical Center from January 2012 to April 2013. The preterm infants were monitored from birth up to 1 year of age and the findings were related to development of allergic disease. Individuals with allergic disease during the first year of life(cases)were matched with gender,as previously described with two individuals(controls)who re-mained event - free during the study. The risk factors associated with allergic disease in preterm infants during the first year of life were analyzed. And whether there was any association between peripheral blood eosinophils and allergic di-sease during the first year of life benefit of a hydrolyzed formula feeding in preterm infants was investigated. Different variables in control and case individuals were compared with t test for normal distribution measurement date,χ2 tests for categorical variables and Mann - Whitney U test for non - normal distribution measurement date,and multiple conditio-nal Logistic regression were used to investigate the risk factors associated with allergic disease in preterm infants. Results Thirty - four individuals were in cases and 68 individuals were in controls. In a conditional multivariable Logistic model,peripheral blood eosinophils of preterm infants at full enteral feeding(EOS - 2)(OR = 5. 941,95% CI:1. 165 - 41. 375,P ﹤ 0. 05),and family history of allergy(OR = 3. 316,95% CI:1. 201 - 9. 152,P ﹤ 0. 05)were the two independent risk factors for allergic disease in preterm infants during the first year of life. Individuals fed with standard preterm formula after birth,the association between EOS - 2 and allergic disease was significantly enhanced (OR = 21. 459,95% CI:1. 686 - 273. 152,P ﹤ 0. 05). By contrast,in individuals fed with hydrolyzed formula,the risk of EOS - 2 was substantially attenuated(OR = 1. 708,95% CI:0. 148 - 19. 743,P ﹥ 0. 05). Conclusions Peripheral blood eosinophils of preterm infants at full enteral feeding EOS - 2 and family history of allergy were the 2 independent risk factors for allergic disease in preterm infants during the first year of life. Contrast to individuals fed with standard preterm formula after birth,individuals fed with hydrolyzed formula had lower association between factors of peripheral blood eosinophils and family history of allergy,and allergic disease during the first year of life.
