BACKGROUNDThe role of tumor-infiltrating lymphocytes (TILs) in the immunopathogenesis of individual cancer is not clear and is a challenge for anti-tumor immunotherapy. This study aimed to investigate the effects of interleukin (IL)-18 and -12 on cytotoxic functions of TILs.

METHODSTILs from postoperative gastric cancer patients were costimulated with IL-18 and IL-12. SGC-7901 tumor cells were pre-incubated with TILs and subcutaneously injected into BALB/C SCID mice. The function of TILs was evaluated by measuring tumor sizes in tumor-bearing mice, T helper (Th)1 (tumor necrosis factor (TNF)-α, interferon (IFN)-γ) and Th2 cytokine levels (IL-10 and IL-4) in serum and cytotoxicity of mouse natural killer (NK) and CD8(+) T cells.

RESULTSIL-18 and IL-12 synergistically inhibited the growth of SGC-7901 cells in vivo and significantly extended the survival rate of SGC-7901-bearing mice (66.7% vs. 13.7%, P < 0.01). Moreover, TILs could promote the secretion of TNF-α and IFN-γ ((130.34 ± 7.65) vs. (210.63 ± 12.31) pg/ml, P < 0.01; (14.23 ± 1.97) vs. (30.52 ± 2.12) pg/ml, P < 0.01), and downregulate IL-10 and IL-4 secretion ((103.72 ± 11.21) vs. (61.36 ± 5.41) pg/ml, P = 0.021; (49.36 ± 4.67) vs. (28.48 ± 3.86) pg/ml, P = 0.024).

CONCLUSIONIL-18 and IL-12 can synergistically enhance cytotoxic functions of TILs from human gastric cancer.

Objective: To observe the clinical efficacy of acupuncture plus MOTOmed intelligent motor training in treating children with spastic cerebral palsy, and analyze the effects on lower limb motor function, intelligence development level, immune function and cerebral hemodynamics.Methods: A total of 42 children with spastic cerebral palsy were selected as the observation objects, and enrolled into the observation group. Another 42 cases treated in the same period were selected as the control group. Both groups received MOTOmed intelligent motor training, and the observation group was given additional acupuncture therapy, and the control group was given additional conventional rehabilitation treatment. After 2 consecutive treatment courses, the psychomotor development index (PDI) and mental development index (MDI) of Children's Developmental Center of China (CDCC) scale, the scores of gross motor function measure (GMFM) scale and modified Ashworth scale (MAS), and the changes in CD3+, CD4+, CD8+ and CD4+/CD8+ were observed. The peak systolic velocity (PSV) and mean flow velocity (MFV) of the anterior cerebral artery (ACA), middle cerebral artery (MCA) and posterior cerebral artery (PCA) were observed and measured. The clinical efficacy was evaluated. Results: Compared with the same group before treatment, the scores of GMFM, PDI and MDI, levels of CD3+, CD4+ and CD4+/CD8+, PSV and MFV levels of ACA, MCA and PCA in both groups were significantly increased after treatment (all P<0.05), while the CD8+ level had no significant change (both P>0.05). After treatment, the total effective rate of lower limb spasm in the observation group was 90.5％, significantly higher than 71.4％ in the control group (P<0.05). The scores of GMFM, PDI and MDI, the levels of CD3+ and CD4+, PSV and MFV, and the levels of ACA, MCA and PCA in the observation group were all significantly higher than those in the control group (all P<0.05). There were no significant differences in the CD8+ level and CD4+/CD8+ between the groups (all P>0.05). Conclusion: Acupuncture plus MOTOmed intelligent motor training has a better clinical efficacy than conventional rehabilitation plus MOTOmed intelligent motor training in treating children with spastic cerebral palsy, and is also superior in improving lower limb motor function and the level of intellectual development. And the mechanism may be related to the improvement of cerebral hemodynamics.

The aim of this study is to observe the therapeutic effect of recombinant murine interleukin 12 (rmIL-12) combining with granulocyte colony stimulating factor (G-CSF) on mice irradiated by γ-rays. 56 BALB/c mice were totally irradiated by 6.0 Gy of (60)Co γ-ray and randomly divided into irradiation control group, rmIL-12 treatment group, G-CSF treatment group and combination therapy (rmIL-12 plus G-CSF) group. rmIL-12 20 µg/kg was administrated intraperitoneally at 1 h following irradiation, and was administrated every 3 days after irradiation for 4 times in rmIL-12 treatment group. G-CSF 100 µg/kg was administrated subcutaneously the 2 h following irradiation for 14 d in G-CSF treatment group. The dose and method of rmIL-12 and G-CSF in combination therapy group were same as in rmIL-12 group and G-CSF group. The general status of mice were observed twice a day, the changes in body weight, peripheral blood cell (WBC and Plt) counts were examined once every three days, bone marrow cells were collected to perform colony cultivation on day 14 and 28 after irradiation. The results showed that WBC count recovery time in combination therapy group was significantly earlier than that of the control group (7 d vs 11 d), WBC count recovery velocity in the combination therapy group was no significant different from that of the G-CSF treatment group. Combined therapy significantly promoted Plt count recovery, resulting in less profound nadirs (16.5% vs 8.1%, P < 0.01) and rapid recovery to normal levels (11 d vs 14 d), Plt count recovery velocity in the combination therapy group was no significant different from that of the rmIL-12 treatment group. Culture of bone marrow cells in semi-solid medium also demonstrated that combination of rmIL-12 and G-CSF could stimulate bone marrow cells to form more CFU-GM and CFU-Mix than those of the irradiation control group in vitro on day 14 and 28 after irradiation (P < 0.05). It is concluded that the combination of rmIL-12 and G-CSF can significantly accelerate the recovery of hematopoietic function in mice with acute radiation sickness.

OBJECTIVETo observe effect of porcine relaxin(pRLX) on NO production of human microvascular endothelial cells(HMVECs) and discuss its possible mechanism.

METHODSiNOS and cNOS expression of HMVECs with or without pRLX were detected using western blotting. NO production of HMVECs with pRLX at different concentration or different time were determined by method of Griess. NO production of pRLX of HMVECs plus Non-selective NOS inhibitor NG-monomethyl-L-arginine(L-NMMA), selective iNOS inhibitor aminoguanidine(AG) or nuclear factors-kappaB (NF-kappaB) inhibitor pyrrolidine dithiocarbamate(PDTC) were also analysed.

RESULTSpRLX promoted iNOS protein expression of HMVECs, but not cNOS protein expression. NO production of HMVECs was promoted by pRLX on concentration-dependent pattern instead of time-dependent one. AG, L-NMMA and PDTC were showed to block the effect of pRLX on NO production of HMVECs.

CONCLUSIONpRLX promote iNOS expression and NO production of HMVECs.

OBJECTIVETo explore the effects of integrative medicine (IM) rehabilitation protocolon motor function, activity of daily living, and quality of life (QOL) in hemiplegia patients after stroke.

METHODSTotally 120 patients with post-stroke hemiplegia were allocated to four groups using sealed envalope drawing, i.e., the rehabilitation group, the Chinese medical treatment group, the acupuncture group, and the comprehensive rehabilitation group, 30 cases in each group. Based on routine rehabilitative training, patients in the Chinese medical treatment group, the acupuncture group, and the compre-hensive rehabilitation group received standardized treatment based on syndrome typing, Shi's Consciousness-Restoring Resuscitation acupuncture, Chinese herbs + acupuncture comprehensive rehabilitatino protocol, respectively. The treatmet cycle consisted of 4 weeks with 24-week follow-ups. Fugl-Meyer motor assessment (FMA), Modified Barthel Index (MBI), and Stroke-Specific Quality of Life Scale(SS-QQL), and safety assessment were taken as main effect indices before treatment, at week 4 of treatment, at week 12 and 24 of follow-ups, respectively.

RESULTSThere was no statistical difference in FMA score, MBI score, SS-QOL score among the four groups before treatment (P > 0.05). These scores were significantly improved in the four groups at week 4 of treatment, week 12 and 24 of follow-ups, respectively (P < 0.05). Besides, FMA score and SS-QOL score were significantly improved in the comprehensive rehabilitation group at each corresponding time point, as compared with other treatment groups (P < 0.05).

CONCLUSIONSThe comprehensive protocol could significantly improve motor function, activity of daily living in hemiplegia patients after stroke, and further improve their QOL. Its effect was better than other single treatment.
