Objective To evaluate the safety of nasogastric tube feeding and nasojejunal tube feeding in early enteral nutrition treatment of acute pancreatitis.Methods Using key words,subject headings,and citation tracing,we searched literatures reporting randomised controlled trials on early enteral nutrition treatment of acute pancreatitis through nasojejunal tube and nasogastric tube in the following databases:PubMed,Embase,Cochrane library,Wanfang,China National Knowledge Infrastructure (CNKI),and VIP published since the founding of the databases up to 2016.Meta-analysis was performed with the selected literature.Results Seven randomised controlled trials with 367 patients were included.Meta-analysis showed that the nasogastric tube group was not inferior to the nasojejunal tube group in the incidence of recurrent abdominal pain,gastrointestinal adverse reaction,the total length of hospital stay,and mortality.Conclusion Enteral nutrition via nasogastric tube is safe and well tolerated,may be a safe approach of nutrition treatment for acute pancreatitis.

BACKGROUND:Fibrin glue is a natural biodegradable scaffold, which can be used for tissue-engineered scaffolds, and is increasingly used as seed cel carrier for tissue engineering repair. OBJECTIVE:To investigate the biocompatibility in vitro of rabbit fascia fibroblasts and fibrin glue. METHODS:Tissue explants adherent method was used to culture fibroblasts from subcutaneous deep fascia tissue of New Zealand white rabbits. The fibroblasts could be passaged with trypsin digestion method. Suspension of passage four fibroblasts was co-cultured with fibrin glue. Morphology and proliferation of fibroblasts on the surface of fibrin glue were dynamical y observed under the inverted phase contrast microscope. At 5 days after co-culture, fibroblasts were identified by immunofluorescence staining under the laser scanning confocal microscope. The fibroblast growth and adhesion were observed under the scanning electron microscope. RESULTS AND CONCLUSION:There was no significant difference in fibroblast morphology between co-culture fibroblasts and pure culture fibroblasts with inverted phase contrast microscope. Scanning electron microscope demonstrated that fibroblasts ful y extended in fibrin glue surface, and showed a good adhesion between the“pseudopodium”and fibrin glue, and secreted matrix material. It is clear that the fibrin glue did not alter the morphologic features of fibroblasts. Laser scanning confocal microscope revealed that fibroblasts were positive for vimentin. These verified that properties of fibroblasts did not change after they were seeded in fibrin glue surface and did not be induced to differentiate. There is a very good biocompatibility between fascia fibroblasts and fibrin glue in vitro.

Objective To investigate the relationship between serum homocysteine (Hcy) and large artery atherosclerosis (LAA).Medods The consecutive stroke patients with LAA and small artery occlusion (SAO) were enrolled.The demographics,baseline clinical data,and laboratory test results were compared.Multivariate logistic regression analysis was used to identify the independent risk factors for LAA.Spearman correlation analysis was used to analyze the correlation between serum Hcy concentration and carotid plaque scores.Results A total of 117 patients with LAA and SAO were enrolled,42 were in the LAA group and 75 were in the SAO group.The plasma Hcy levels (median [interquartile range] 15.35 [12.20-20.43] μmol/Lvs.12.40 [10.40-15.00] μmoFL; Z=-2.540,P=0.011),the carotid plaque scores (6.30 ±4.11 mm vs.4.19 ±2.84 mm; t =2.952,P=0.004),and the proportion of plasma Hcy level at tertile groups of the patients (x2 =10.697,P =0.005) of the LAA plasma group were all significantly higher than those of the SAO group.Multivariate logistic regression analysis showed that the plasma Hcy concentration was in the third tertile (＞ 15.3 μmol/L),and it was an independent risk factor for LAA (odds ratio 4.739,95％ confidence interval 1.696-13.241; P =0.003).Moreover,there was a significant positive correlation between the serum Hcy concentration and the carotid plaque scores (r =0.245,P =0.008).Conclusions The plasma Hcy levels were positively correlated with the severity of carotid atherosclerosis.The Hcy ＞ 15.3 μmol/L was an independent risk factor for LAA.

OBJECTIVETo evaluate digital rectal examination (DRE) , transrectal ultrasonography (TRUS) , free/total (f-PSA/ t-PSA) prostate-specific antigen (PSA), and PSA density (PSAD) in the diagnosis of prostate cancer (PCa) in patients with PSA < or = 4.0 microg/L.

METHODSBetween April 1996 and December 2012, a total of 343 subjects, aged 30 -91 years, with PSA < or =4.0 microg/L and abnormal findings on DRE or TRUS underwent prostatic biopsy. Based on the levels of PSA, the subjects were divided into four groups: 0 -1.0, 1.1 -2. 0, 2.1 -3. 0, and 3.1 -4.0 microg/L. The diagnostic values of DRE, TRUS, f-PSA/t-PSA, and PSAD were assessed in those with different PSA levels. According to the age, the subjects were again divided into five groups: C49 yr, 50 -59 yr, 60 -69 yr, 70 -79 yr, and > 80 yr. The rates of PCa detection in relation to PSA levels were estimated in different age groups.

RESULTSOf the 343 subjects, 65 (19.0% ) were diagnosed with PCa, with detection rates of 16.28% (21/129) , 17. 17% (17/99), 21.82% (12/55), and 25.00% (15/60) in those with the PSA levels of 0 -1.0, 1.1 -2.0, 2.1 -3.0, and 3.1 -4.0 microg/L, respectively. There were statistically significant differences in f-PSA/t-PSA between the PCa patients and non-PCa subjects with the PSA level > 2.0 microg/L (P <0.05) , but not with the PSA level < or =2.0 microg/L (P > 0.05) , nor did PSAD show any significant difference between the PCa and non-PCa groups ([0.09+/-0. 16] versus [0. 06 +/- 0. 07] micro/L/ml, P > 0. 05). The rate of cancer detection rose -with the elevation of the PSA level, but had no statistically significant difference among different age groups (P >0.05).

CONCLUSIONPSA 2.1 -4.0 microg/L with abnormal DRE and TRUS findings should be considered as a warning signal, which requires regular follow-up and PSA detection. With f-PSA/t-PSA <0. 15 with or without abnormal DRE and TRUS findings, routine prostate biopsy should be performed. PCa diagnosis cannot be effectively established by DRE, TRUS, f-PSA/t-PSA, and PSAD in those with PSA < or = 2.0 microg/L.
