Objective To investigate the safety and effectiveness of different nutrition support pathways after gastrectomy.Methods Clinical data of patients with gastric cancer received surgery treatment at our hospital from 2011 to 2013 were retrospectively analyzed.Patients were divided into 3 groups according to different nutrition support pathways,including group A (jejunostomy),group B (intraoperative nasal-bowel tube),and group C (parenteral nutrition).Results A total of 85 patients was retrospectively analyzed,including 28 in group A,26 in group B,and 31 in group C.The exhaust time had significant difference between groups A and B (t =2.312,P =0.02),and between groups A and C (t =3.323,P =0.005).The defecation had significant difference between groups A and B(t =4.211,P =0.001),and between groups B and C(t =3.402,P =0.004).There was significant difference in the adverse effect rate(x2 =6.611,P =0.037) and in hospital stays(P ＜0.01) among 3 groups.The hospitalization expense had significant difference between groups A and C (t =4.012,P =0.001),and between groups B and C (t =5.152,P =0.001).Conclusions Nutrition support via jejunostomy after gastrectomy was better than the other two pathways in the safety and effectiveness.

Angiopoietin-like 4(ANGPTL4)is one of the angiopoietin family members and plays a regulatory role in lipid metabolism,glucose homeostasis,inflammatory signal transduction,angiogenesis and vascular permeability.Inflammatory reaction in tumor microenvironment regulates tumor progression,and tumor angiogenesis plays a vital role in tumor growth and metastasis,so ANGPTL4 is closely related to tumor occurrence and development.Many studies have shown that ANGPTL4 plays an important regulatory role in tumor growth,anoikis resistance,tumor angiogenesis and tumor metastasis.This paper reviews the role of ANGPTL4 in tumor progression.

One hundred and sixty-two low back pain cases due to intervertebral disc problem were treated by puncturing 30 mm in depth with even reinforcing and reducing manipulation on Jiaji points (Ex-B 2) in the lumbar area plus patterned oral herbal decoction, Tao Hong Siwu Decoction. The result showed that 65 cases got marked effect, 53 cases got good effect, 37cases got certain effect, 6 cases got no effect and the total effective rate was 96.3%.

The achievements in recent research on osteogenetic induction of extracorporeal shock wave (SW) are introduced. The mechanism of osteogenesis inducted by SW and its effect of bone repairing are explained emphatically. Besides, the development prospects of SW in healing human disease are described and is indicated that SW will maybe a clinical method for osteoporosis and other disease in orthopedics according to its osteogenetic mechanism.

To investigate the inhibition of HBV expression by multi-target ribozyme-expressing adenovirus vector in vivo, the ribozyme and muta-ribozyme were cloned into adenovirus vector pAd-CMV. By using the adenovirus expression system, the two plasmids were co-transfected into 293 cell line with adenovirus gene recombinant plasmids pJM17. The recombinant adenovirus were detected by plaque assay. Then the recombinant adenovirus infected the 2.2.15 cells. Using ELISA, dot-bolt hybridization and image analysis system, the inhibition of HBV expression was detected. The ribozyme and muta-ribozyme were cloned into the adenovirus vector pAd-CMV. The recombinant adenovirus could infect 2.2.15 cells and express the ribozyme. The ribozyme could decrease the expression of HBeAg by 87.1%. All these results strongly indicate that ribozyme can inhibit HBV expression in the cell, which represents a potential gene therapy for HBV infection.

Objective To investigate the change in the function of the motor nerve fibers of the sciatic nerve of rat following injection of different neurolytic drugs. Methods Thirty-five SD rats weighing 350-380 g were randomly divided into 7 groups ( n = 5 each): group C received normal saline; group Ad adriamycin 5 mg/ml;group Aa anhydrous alcohol; group Pg1 8% phenol-glycerol; group Pg2 10% phenol-glycerol; group Pg3 12% phenol-glycerol and group Ci cidomycin 4000 U/ml. 0.2 ml of the different neurolytic drugs was injected at the points where the branches of the sciatic nerve entering semi-membranous and adductor magnus muscles. The action potential and conduction velocity of motor and sensory nerve fibers were measured at 21 d after injection. Results The conduction velocity of sensory nerve fibers was 0 in each group. The conduction velocity and action potential of the motor nerve fibers were significantly decreased in group Ad, Aa, Pg1, Pg2, Pg3 and Ci as compared with group C (the control group). The action potential and the conduction velocity were significantly higher in group Ad than in other neurolytic drug groups. The potential and the conduction velocity were the lowest in group Aa and Pg3.The conduction velocity in group Pg1, Pg2, Ci was comparable. Conclusion 5% adriamycin seems to be a better neurolytic drug with less interference with function of motor never fibers.

Objective To quantitatively analyze the mRNA and protein expression level of a proliferation-inducing ligand (APRIL) and investigate its clinical significance in peripheral blood mononuclear cells and plasma from newly diagnosed patients with B-cell chronic lymphocytic leukemia (B-CLL).Methods The mRNA of the target gene in 32 B-CLL patients and 15 health controls was quantified with real-time fluorescence quantitative polymerase chain reaction (RFQ-PCR) and protein by enzyme-linked immunosorbent assay (ELISA).Results APRIL mRNA was assayed with RFQ-PCR,the intra-and inter-batch reproducibility showed the coefficient of variation (CV) were 1.69 ％-6.98 ％ and 6.49 ％-10.27 ％,respectively.The expressions of APRIL mRNA and protein in patients with B-CLL were significantly higher than those in control (P ＜ 0.05),and significant difference was noted among the comparable stages in the arms (P ＜ 0.05).The expression of APRIL mRNA and protein in TDI (treatment-demand-indicator) arm was significantly higher than those in non-TDI arm (P ＜ 0.05).Conclusions APRIL may be involved in the formation and development of B-CLL and be an influence factor for disease staging.Thus,APRIL may be a prognostic indicator as well as the therapy target for the disease.

Objective To investigate mRNA and protein expression of aproliferation-inducing ligand (APRIL) in peripheral blood mononuclear cell and plasma of patients with B cells non-Hodgkin lymphoma (B-NHL) pre- or post- chemotherapy and to explore the role of APRIL in the B-NHL. Methods The mRNA and protein expression of APRIL were detected by real-time fluorescence quantitative polymerase chain reaction (RFQ-PCR) and enzyme-linked immunosorbent assay(ELISA), respectively. According to the standard curves,the quantitative levels of target mRNA and protein were determined. Results The detection linear range of targeted mRNA by RFQ-PCR was 101-109 pg/ml, and the coefficient of variation values for both intra- and inter-experimental reproducibility ranged 1.69 %-5.99 % and 6.35 %-10.12 %, respectively. To detect expression of APRIL protein by ELISA, the correlation coefficient of standard curves reached 0.9922. Before or after chemical treatment, the expression levels of APRIL mRNA and protein in patients with B-NHL were significantly higher than those in normal control (P ＜0.01), while the expression levels in post-treatment patients with Ⅲ and Ⅳ stage were lower than those of pre-treatment patients with corresponding stage (P ＜0.05, respectively), but those of pre- and post-treatment patients with Ⅰ / Ⅱ stage were not different (P ＞0.05).Conclusion The expression level of APRIL mRNA is similar to that of APRIL protein. APRIL may be involved in pathogenesis and development of B-NHL. Moreover, APRIL may be related to the burden of B-NHL and it may be considered as a targeted molecule for B-NHL.
