Objective To investigate the effects of enteral nutrition with galactooligosaccharides (GOS) on serum inflammatory cytokines in rats with severe acute pancreatitis (SAP). Methods SD rats were randomly divided into sham operation control group, SAP with enteral nutrition (EN) group and SAP with EN supplemented with GOS (GOS-EN) group, and each group was divided into 4 d and 7 d subgroups according to the time that animals were sacrificed (n=8 in each subgroup). Rat SAP models were established by injection of 38 g/L sodium taurocholate beneath the pancreatic capsule. The serum amylase, inflammatory cytokines TNF-α, IL-2 and IL-10 were detected. Results At each time point, the levels of serum amylase in all SAP groups were significantly higher than those in sham operation control group (P < 0.01), and the levels in GOS-EN group were significantly lower than those in EN group (P < 0.01). The levels of serum TNF-α and IL-10 in all SAP groups were significantly higher than those in sham operation control group (P < 0.01), while the levels of IL-2 in all SAP groups were significantly lower than those in sham operation control group. The levels of TNF-α in GOS-EN group were significantly lower than those in EN group (P <0.05), while the levels of IL-2 and IL-10 and the ratio of IL-10/TNF-α were significantly higher than those in GOS-EN group (P < 0.05). Conclusion Early EN supplemented with GOS could modulate the balance of pro- and anti-inflammatory response.

Integrins are a family of cell surface glycoproteins that contribute to a variety of biological functions, including cell growth, migration, proliferation and morphology. In addition, integrins also play the important roles in pathological process. Several viruses have been showed to use integrins as receptors or co-receptors to infect host cells.This article mainly reviews the progress on integrins and their roles in FMDV infection.

Receptors are primary determinant of viral tropism and disease pathogenesis.Heparan sulfates (HS)are ubiquitous,polyanionic carbohydrate chains linked to core proteins in cell membranes and ex- tracellular matrices of all eukaryotes.HS have also been demonstrated to function as receptors or co-receptors for a number of different viruses.To date,HS and four RGD-dependent integrins,?v?3,?v?6, ?v?1,and?v?8 have been reported to serve as receptors for Foot-and-mouth disease virus(FMDV).Different receptors may be used to interact with host cells during FMDV infection.Studies on the structure and function of receptors are very important for understanding the interaction between host cells and FMDV. Here,We mainly reviews the progress on the biological characteristics of HS and its roles in FMDV infection.

Objective　To investigate the mechanism affecting on permeability of vascular endothelial cell by nitric oxide (NO). Methods　Series concentration of sin-1（a donor of NO） were added to ECV 304, a cell line of human umbilical vein endothelium. Cell growth and expression of f-actin, a cytoskeleton protein were observed. Results　Cell growth was inhibited with a dose from 6.25 to 100 μmol/L and was caused to death at the concentration of 50 to 100 μmol/L by sin-1. The expression of f-actin was suppressed obviously after cultured with 100 μmol/L sin-1 for 4 hours. Conclusion　It suggests that anomaly increased NO can increase permeability of blood vessels by suppressing the expression of f-actin, inhibiting cell growth or even resulting in cell death.

Objective To study and analyze the effects of triple therapy (clarithromycin, amoxicillin, and lansorazole) combined with psychological intervention in the treatment of elderly peptic gastric ulcer. Methods 100 patients with aged gastrointestinal ulcer who were admitted to the hospital from February 2015 to April 2016 were selected as the study subjects, randomly divided into the control group and the experimental group, and 50 patients in each group.The control group was treated with conventional treatment, the experimental group was treated with triple therapy (clarithromycin, amoxicillin, lansorazole) combined with psychological intervention therapy, pay attention to the psychological state of the patients, strengthen the communication and exchanges with the patient, the treatment of patients with increased confidence and treatment compliance. The treatment effect of the experimental group and the control group was compared. Results After the corresponding treatment, the effective rate of treatment in the experimental group was 96.0%, significantly higher than the control group (86.0%), the difference was statistically significant (P<0.05). No obvious adverse reactions were found in the experimental group and the control group. The recurrence rate in the control group was 400%, which was significantly higher than that in the experimental group (14.0%), the difference was statistically significant (P<0.05). Conclusion Triple therapy (clarithromycin, amoxicillin, lansorazole) combined with psychological intervention in treatment of elderly peptic ulcer effect is good, can significantly improve the treatment efficiency, the recurrence rate is low.

OBJECTIVETo study the influence of the reference values for semen analysis proposed in the 5th edition of the WHO Laboratory Manual for the Examination and Processing of Human Semen on the indication spectrum for intrauterine insemination (IUI).

METHODSWe retrospectively analyzed the clinical data of 111 cycles of IUI by the reference values for semen analysis in the 4th edition of the WHO Laboratory Manual (group A) and 84 cycles by the 5th edition (group B). We recorded and compared the percentages of various indications for IUI between the two groups.

RESULTSThe complications for IUI in groups A and B were as follows: asthenospermia (87.4% [97/111] vs 55.9% [47/84], P < 0.05), oligospermia (0 vs 0), teratospermia (51.4% [57/111] vs 35.7% [30/84]) , abnormal liquefaction (0.9% [1/111] vs O) , sexual dysfunction and genital malformation (0 vs 3.6% [3/84] , immune infertility (0.9% [ 1/111] vs O), and unexplained infertility (3.6% [4/111] vs 2. 4% [2/84 ] ). There were no significant differences between the two groups in the percentages of all the indications except that of asthenospermia.

CONCLUSIONThe reference values for semen analysis proposed in the 5th edition of the WHO Laboratory Manual for the Examination and Processing of Human Semen have an evident influence on the indication spectrum for IUI by largely reducing the cases of IUI for male factors, prolonging the cycles of some patients, causing excessive diagnosis and treatment for females, and increasing their mental and economic burdens.

Receptors play a crucial role in determining the host specificity and tissue tropism of virus. Foot-and-mouth disease virus(FMDV)has been showed to use four integrins, ?v?1, ?v?3, ?v?6 and ?v?8 as receptors to initiate infection and ?v?6 functions as the major receptor.The cDNA encoding bactrian camel integrin ?6 from the lung tissue was cloned and sequenced. The 2367bp cDNA of bactrian camel integrin ?6 encodes a polypeptide of 788 amino acids consisting of a 26-residue putative signal peptide, a 681-residue ectodomain with 8 potential N-linked glycosylation sites and 58 cysteine residues, a 29-residue transmembrane domain, and a 52-residue cytoplasmic domain with a NPLY motif and 1 potential N-linked glycosylation site. The nucleotide sequence similarity of integrin ?6 between bactrian camel and cattle, pig, sheep, human, mouse, Norway rat is 91.1%、91.8%、90.6%、90.5%、83.7%、84.1%, and the amino acid sequence similarity is 94.3%、93.4%、93.4%、93.7%、88.7%、88.6%, respectively. The bactrian camel ?6 gene exhibited the higher sequence homology with the ?6 gene of cattle, pig and sheep, indicating their close genetic relationships. It is possible that host tropism of FMDV may related to divergence in ?6 receptors among different species.
