ABSTRACT

Objective:To explore the effect of pelvic floor muscle functional exercise based on Snyder hope theory in patients after prophylactic stoma retraction.Methods:74 patients with low rectal cancer who underwent prophylactic stoma retraction from July 2019 to June 2021 were randomly divided into intervention group and control group. The patients in the control group received routine nursing and pelvic floor muscle functional exercise. The patients in the intervention group received functional exercise intervention based on Snyder′s hope theory on the basis of the control group. The hope level and self-care ability of the patients in the two groups were evaluated before the intervention and 3 months after stoma restitution. The anal function of the patients in the two groups was evaluated 1 month and 3 months after stoma restitution.Results:Before the intervention, there was no significant difference in the score of hope level and self-care ability between the two groups ( P>0.05). Three months after the operation, the score of hope level in the observation group was 36.20 ± 3.82, which was higher than that in the control group (31.26 ± 5.03) ( t = 4.63, P<0.05). Three months after the operation, the self-care ability score of the observation group was 123.57 ± 10.82, which was higher than that of the control group (108.23 ± 9.48) ( t = 6.31, P<0.05). One month and three months after stoma retraction, the anal function scores of the observation group were 12.03 ± 3.94, 5.91 ± 2.05 respectively, which were lower than those of the control group (13.86 ± 2.19, 7.26 ± 1.74) ( t = 2.40, 2.99, both P<0.05). Conclusion:Pelvic floor muscle functional exercise based on Snyder′s hope theory can improve the hope level of patients after stoma retraction, improve their anal function and improve their self-care ability.

ABSTRACT

Objective To research the immuno-protection of SJIR-2 DNA vaccine with nanometer microspheres a-gainst Schistosoma japonicum infection in mice. Methods To construct eukaryotic expression plasmid pEGFP-SJIR-2, identified by double digestion and sequenced delivery. The recombinant plasmid pEGFP-SJIR-2 was ex-tracted and was encapsulated into PLGA nanometer microspheres which were modified by CHS. 40 female BALB/c mice were randomly divided into 4 groups (n=10), each group of mice were injected with PBS, empty pEGFP plasmid, CHS-PLGA nanometer microspheres and CHS-PLGA-pEGFP-SJIR-2 nanometer microspheres 100 μg, re-spectively. Two weeks after the last immunization, each mouse was infected by cercaria of Schistosoma japonicum, sera of mice in each group were collected before each immunization and challenge infection. ELISA was used to de-tect the change of IgG in each group of micesera. 42 days later, all mice were sacrificed. The adult worms and eggs were collected and counted, and the worm and egg reduction rates were calculated as well. Results The recombi-nant plasmid pEGFP-SJIR-2 was successfully constucted, and there was significant difference in the numbers of worm and egg between CHS-PLGA-pEGFP-SJIR-2 group and PBS group ( P<0. 01 ) . The worm andegg reduction rates in CHS-PLGA-pEGFP-SJIR-2 group were 37. 36% and 46. 82% respectively. The IgG levels in mice sera of CHS-PLGA-pEGFP-SJIR-2 group were remarkably higher (P<0. 01) compared with PBS group. On the contrary, there was no significant difference between both pEGFP plasmid group and CHS-PLGA group in the numbers of worm and egg compared with PBS group. Conclusion SJIR-2 nanometer microspheres nucleic acid vaccine has some immuno-protection against Schistosoma japonicum infection in BALB/c mice,while it is worth further studying for it’ s potential value to be a candidate antigen molecule of Schistosoma japonicum vaccine.

ABSTRACT

This study investigated the effect of arctigenin (Arc) on the cell activation, cytokines expression, proliferation, and cell-cycle distribution of mouse T lymphocytes. Mouse lymphocytes were prepared from lymph node and treated with Phorbol-12-myristate-13-acetate (PMA)/Ionimycin (Ion) and/or Arc. CD69, CD25, cytokines, proliferation and cell cycle were assayed by flow cytometry. The results showed that, at concentrations of less than 1.00 micromol x L(-1), Arc expressed non-obvious cell damage to cultured lymphocytes, however, it could significantly down-regulate the expression of CD69 and CD25, as well as TNF-alpha, IFN-gamma, IL-2, IL-4, IL-6 and IL-10 on PMA/Ion stimulated lymphocytes. At the same time, Arc could also inhibit the proliferation of PMA/Ion-activated lymphocytes and exhibited lymphocyte G 0/G1 phase cycle arrest. These results suggest that Arc possesses significant anti-inflammatory effects that may be mediated through the regulation of cell activation, cytokines expression and cell proliferation.

ABSTRACT

Bcl-2 gene is the human homologous gene of anti-apoptotic gene Ced-9 in c-elegans, which can participate in regulations of cells apoptosis including suppression of neuronal apoptosis in cerebral ischemic penumbra.This review is about Bcl-2 anti-ischemic neuron injury, its possible mechanisms and the effects of anti-ischemic drugs on Bcl-2.
