ObjectiveTo investigate the intervention effects of moxibustion and moxa smoke on blood lipids,hepatic pathological changes and intrahepatocytic molecules related to cholesterol metabolism and analyze the regulating effects of moxibustion and moxa smoke on cholesterol metabolism and explore the mechanisms of actions of moxibustion and moxa smoke. MethodFifty-one 8-week-old ApoE-/-mice were randomized into model, moxa smoke and moxibustion groups, 17 mice each. Twenty C57BL/6 mice comprised a blank control group. The normal and model groups of mice were routinely grabbed and fastened. The moxa smoke group of mice was exposed to 10-15 mg/m3moxa smoke circumstances. The moxibustion group of mice was given moxibustion on point Guanyuan(CV4). All interventions were made 20 min daily, 6 times a week, for 12 consecutive weeks. Total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C) and low density lipoprotein-cholesterol (LDL-C) were measured using an automatic biochemical analyzer. Hepatic pathologic morphology was observed by HE staining. Hepatic CD36 and ABCA1 expressions were determined by immunohistochemical method.ResultIn the model group of mice, serum TG and LDL-C contents were significantly higher than in the normal group (P=0.003;P=0.001);HDL-C content was significantly lower than in the normal group (P=0.007); TC content had no significant difference compared with the normal group (P>0.05). In the moxibustion group of mice, serum TG and LDL-C contents were significantly lower than in the model group (P=0.03;P=0.001) and HDL-C content had no significant difference compared with the model group (P=0.11). In the moxa smoke group of mice, serum TG and LDL contents were significantly lower than in the model group (P=0.01;P=0.008) and HDL content had no significant difference compared with the model group (P=0.11). There were no significant differences in various blood lipid indicators between the moxibustion and moxa smoke groups (P>0.05). There were hepatic cell cord and sinusoid derangement and obvious hepatocytic swelling in the model group of mice. In the moxa smoke and moxibustion groups, hepatocytic swelling subsided significantly, and inflammatory cell infiltration reduced compared with the model group. In the model group,CD36 expression was significantly higher than in the normal group (P=0.004) and ABCA1 expression was significantly lower than in the normal group (P=0.001). In the moxibustion group, CD36 expression had no significant difference compared with the model group (P=0.09) and ABCA1 expression was significantly higher than in the model group (P=0.03). In the moxa smoke group, CD36 expression was significantly lower than in the normal group (P=0.02) and ABCA1 expression was significantly higher than in the model group (P=0.002). There were no significant differences in CD36 and ABCA1 expressions between the moxibustion and moxa smoke groups (P>0.05).ConclusionEarly moxibustion on point Guanyuan can regulate disorders of blood lipid metabolism, delay the occurrence of hepatic lesions and reduce intrahepatic accumulation of cholesterol to a certain extent in an ApoE-/-mouse model of atherosclerosis. That may be one of the mechanisms by which moxibustion therapy prevents atherosclerosis. Moxa smoke as the product of moxibustion is an effective factor in moxibustion producing a therapeutic effect.

Objective To observe the effect of PM10 (inhalable particles) in moxa smoke on apoptosis of human lung adenocarcinoma cell line-A549 cells, and explore the possible mechanisms of inducing apoptosisMethods The A549 cells were studied in vitro experiment method, which were stained by Hoechest33258 staining method. Their morphological changes of apoptosis were observed by the fluorescence microscopy. The levels of intracellular Ca2+ and reactive oxygen species (ROS), and expression of NF-κB p65 were also measured.Results Some apoptotic cells were observed after treated with moxa smoke PM10 in the concerntration of 400μg/mL. After 4 hours intervention by moxa smoke PM10 in A549 cells, the intracellular Ca2+ level increased significantly (P<0.01). Compared with the blank control group, the expression of NF-κB p65 decreased significantly (P<0.05) after intervention of moxa smoke PM10 with different concerntrations for 4 hours. When the A549 cells were cultured with moxa smoke PM10 for 20 hours, the expression of p65 decreased significantly (P<0.05) in the concerntrations of 70, 280μg/mL, while there was no significant change in the concerntration of 140μg/mL (P>0.05). Compared with the blank control group, ROS level was significantly lower (P<0.05) in A549 cells after intervention of moxa smoke PM10.Conclusion PM10 in moxa smoke could induce apoptosis of A549 cells, could increase cytosolic Ca2+ level.

New strategies to improve vaccine efficacy against human immunodeficiency virus type 1 (HIV-1) are still required. DNA vaccines, exhibiting potential advantages over conventional vaccines for their simplicity and versatility, can induce specific humoral and cellular immune responses. We developed a recombinant pVAX1 DNA vector carrying p24 gene of HIV-1. The results showed that pVAX1 mediated gene possessed the ability of effective expression in both transfected 293T cells and BALB/c mice. And pVAX1-p24 DNA prime and boost immunization can induce significant P24-specific humoral immune responses and cellular immune responses in BALB/c mice. Furthermore, immunization with pVAX1-p24 DNA prime and protein boost induced 7.3 to 8.0-fold greater p24-specific humoral responses than pVAX1-p24 DNA prime and boost, while the cellular immune responses induced by combined immunization was lower. The results suggested that pVAX1-p24 DNA and P24 protein vaccine is a promising HIV-1 vaccine, and the selections of the immunization strategies are important for the immunization results.

OBJECTIVETo develop a new vaccine expressing membrane-bound heat shock protein 70 (mbHSP70) and further study its antitumor therapeutic effect.

METHODThe pre- established vector expressing mbHSP70 was transfected into CT26 cells of colorectal cancer. After the CT26 cells were incubated with 900 microg/ml G418, the sub-clones resistant to G418 were harvested and the HSP70 positive clones were selected by limiting dilution. The clones were amplified and inactivated, thereby the vaccine expressing mbHSP70 was prepared. Lymphocyte proliferation stimulated by the vaccines, NK and CTL activity was observed. The antitumor efficacy of vaccine was observed in BALB/c mice model with colorectal cancer.

RESULTSThe laser confocal microscopy and flow cytometry showed that there existed much HSP70 on the vaccine membrane surface. The HSP70 gene-modified vaccine displayed augmented lymphocyte proliferation and higher NK and CTL activity in vitro,and marked tumor suppression and prolonged survival time of the vaccinated micein vivo, when compared with its counterpart. Furthermore, mbHSP70-expression vaccine elicited lymphocyte proliferation most intensively, generated the highest NK and CTL activity as well as the strongest antitumor effect, and prolonged survival time of the vaccinated mice.

CONCLUSIONA new vaccine expressing mbHSP70 has more potent antitumor immunity and better therapeutic efficacy than HSP70 gene-modified vaccine did.
