Effect of Yiqi Jianpi plus anticancer herbs on spleen deficiency in colorectal cancer and its anti-tumor role

Objective:To observe the effect of Yiqi Jianpi plus anticancer herbs on spleen deficiency in colorectal cancer and its anti-tumor role.Methods:Human intestinal cancer cell HT29 xenograft of nude mice model was established.The expression of ECF,VEGF,gastric cancer tumor growth in mice were observed.Results:Protein kinase C expression in in the Yiqi Jianpi group and Yiqi Jianpi anti-tumor group was significantly better than the model group(P<0.01,P<0.05).There was significantly more apoptotic cells in Yiqi Jianpi anti-tumor group than Yiqi Jianpi group and model group(P<0.01).Epidermal growth factor and vascular endothelial growth factor expression in Yiqi Jianpi group was significantly lower than Yiqi Jianpi group and model group(P<0.05).Conclusions:Tumor can inhibit the expression of PKC inhibition.Yiqi Jianpi and anticancer treatment can reduce this inhibition.Besides this treatment can also inhibit expression of tumor related genes such as epidermal growth factor and vascular endothelial growth factor.

Effect and Mechanisms of Gong-Tone Music on the Immunological Function in Rats with Liver(Gan)-Qi Depression and Spleen(Pi)-Qi Deficiency Syndrome in Rats

Objective： To investigate the effects and mechanisms of Gong-tone music on the immunological function in rats with the Chinese medicine syndrome of Liver （Gan）-qi stagnation and Spleen （Pi）-qi deficiency （LSSD）. Methods： Twenty five male Wistar rats of SPF grade were randomly divided into 5 groups： normal group, model group, Xiaoyao Powder （逍遥散） group, Gong-tone group and combined group （the combination of Gong-tone and Xiaoyao Powder）, with 5 rats in each group. The rat model for the Chinese medicine syndrome of LSSD was induced by chronic bandage and irregular diet. The course of treatment was 21 days. After the treatment, the levels of serum gastrin and IgG were detected by enzyme-linked immunoabsorbent assay （ELISA）. Phagocytosis of macrophages was detected by the neutral red uptake assay and T cell proliferation was investigated by 3-（4,5-dimethylthiazolyl）-2,5-diphenyltetrazolium bromide （MTT） assay. Results： The serum gastrin, macrophage phagocytosis, IgG level and proliferation ability of T cells in the model group were significantly decreased compared with those in the normal group （P〈0.05）. Compared with those in the model group, the serum levels of gastrin, macrophage phagocytosis, IgG level and proliferation ability of T cells in Gong-tone, Xiaoyao Powder, and combined groups were significantly increased （P〈0.05）. The combined group was superior to either Gong-tone group or Xiaoyao Powder group. Conclusion： Gong-tone music may upregulate the immunological function and play a role in adjuvant therapy in the Chinese syndrome of LSSD.

Efficacy of Sijunzi decoction(四君子汤) on limb weakness in spleen Qi deficiency model rats through adenosine monophosphate-activated protein kinase/unc-51 like autophagy activating kinase 1 signaling

OBJECTIVE:To investigate the efficacy of Sijunzi decoction(四君子汤)on limb weakness in a rat model of spleen Qi deficiency(SQD),and to study its effect on mitophagy in skeletal muscle through adenosine monophosphate-activated protein kinase(AMPK)/unc-51 like autophagy activating kinase 1(ULK1)signaling.METHODS:SQD model rats were produced by fasting combined with forced swimming method for15 d.After model assessment,rats were randomly divided into four groups of 10[low/middle/high(L/M/H)Sijunzi decoction dose groups and a normal saline(S)group].Limb holding power(HP)and body mass(BM)were measured after 2 weeks of treatment.Following euthanasia,quadriceps femoris were dissected and myofiber and mitochondrial morphology were observed by transmission electron microscopy(TEM).Mitochondrial membrane potential(MMP),adenosine triphosphatase(ATP)and reactive oxygen species(ROS)levels were determined using colorimetric methods,and immunoblot analysis of Microtubule-associated protein light chain 3(LC3)and Sequestosome 1(p62)was performed to monitor mitophagy and AMPK/ULK1 signaling.RESULTS:Compared with control(C)group rats,in the S group,HP was reduced,the myofiber Z line was disordered,mitochondria were scattered,and numerous vacuoles and mitophagy were observed.MMP and ATP levels were reduced,ROS levels were elevated,and LC3B expression,and p-AMPKα(Thr172)/AMPKα,p-ULK1(Ser555)/ULK1,and p-Raptor(Ser792)/Raptor ratios were increased,while p62 expression and p-mT OR(Ser2448)/mT OR and p-ULK1(Ser757)/ULK1 ratios were decreased.After treatment,compared with the S group,HP was improved in M and H groups but not in the L group.Mitophagy was reduced in M,H and L groups but the Z line was disordered and vacuolization remained in the L group.ATP levels were elevated in M,H and L groups,and MMPs were elevated in M and H groups but not in the L group.ROS levels were decreased in M,H and L groups,as were LC3B expression and p-Raptor(Ser792)/Raptor ratios,while p62 expression and p-mT OR(Ser2448)/mT OR and p-ULK1(Ser757)/ULK1 ratios were increased in M and H groups but not in the L group.p-AMPKα(Thr172)/AMPKαand p-ULK1(Ser555)/ULK1 ratios were decreased in M,H and L groups.CONCLUSIONS:Sijunzi decoction improved HP,possibly by inhibiting mitophagy via suppression of AMPK/ULK1 signaling.This restored mitochondrial morphology and improved oxidative phosphorylation,which contributed to recovery of limb weakness in SQD model rats.

Clinical Observation on Effect of Kanglaite(康莱特)in Treating Pulmonary Carcinoma Patients withLung-Qi Deficienoy and ImmunologicInadequacy sfter Pneumonectomy

Objective: To study the effect of Kanglaite (KLT) in treating pulmonary carcinoma (PC) patients with Lung-Qi Deficiency and immunologic inadequacy (LDII) after pneumonectomy. Methods: Thirtysix patients of PC-LDII were treated with KLT and the lymphocyte subset was examined before and after treatment. Results: The markedly effective rate of treatment was 50. 0 % and the total effective rate 66. 7%. Immunological examination showed that the lymphocyte subset of patients tended to get normal and the difference between pre-treatment and post-treatment was significant. Conclusion: KLT could improve the symptom ofLung-Qi Deficiency and markedly strengthen the immune function of PC patients.
