Chinese Journal of Integrated Traditional and Western Medicine 2015;35(3):287-289
OBJECTIVETo observe the effect of Angong Niuhuang Pill (ANP) on Thl/Th2 in cerebral infarction patients and to explore the mechanism of phlegm-heat obstructing orifices.
METHODSRe- cruited were 30 cerebral infarction patients of phlegm-heat obstructing orifices syndrome (PHOOS) both in China and Indonesia. They were assigned to 4 groups according to the use of ANP, the Chinese treatment group, the Indonesia treatment group, the Chinese control group, and the Indonesia control group. Patients in the two control groups received conventional treatment, while those in the two treatment group additionally took ANP for 30 successive days. Their adverse reactions were observe, and levels of INF-γ and IL-4 were detected.
RESULTSThe INF-γ level and the INF-γ/IL-4 ratio significantly decreased, and the IL-4 level increased after treatment in the four groups with statistical difference (P < 0.05). Compared with the control group after treatment in the same country, the INF-γ level and the INF-γ/IL-4 ratio were lower, and the IL-4 level was higher in the two treatment groups (P < 0.05). Compared with the two Chinese groups, the INF-γ level and the INF-γ/IL-4 ratio were higher, and the IL-4 level was lower in the two Indonesian groups (P < 0.05). There was no statistical difference in the post-treatment indices between the two treatment groups.
CONCLUSIONSANP had moderating effect on Th1/Th2 in cerebral infarction pa- tients. Cerebral infarction patients of PHOOS might exist certain relation with Th1/Th2.

Intersectin is an evolutionarily conserved multifunctional adaptor protein with multifunctional domains. These domains interact with components of the endocytic and exocytic pathways, such as the clathrin mediating synaptic vesicle recycling, the protein related to endocytosis via caveolae, the with-no-lysine kinases related to the regulation of renal outer medullar potassium, and the Cdc42 mediating exocytic pathway. Recently, the understanding of intersectin function in the pathogenesis of endocrine tumor and many neurodegenerative diseases such as Down syndrome, Alzheimer disease has been deepened. This article reviewed the structure and roles in endocytosis/exocytosis and diseases of intersectin.

OBJECTIVETo investigate the expression of Tenascin-C mRNA in keloids and hypertrophic Total RNA was isolated from normal adult skin. A cDNA fragment (base 5941-6481bp) of the scars.
METHODSfull-length human Tenascin-C cDNA was synthesized by polymerase chain reaction and subcloned in pGEM-T-easy. Dioxygen-labeled anti-sense and sense probes were synthesized by using a Sp6/T7 RNA synthesis kit in the present of Dig-UTP in vitro. The samples were taken from keloids in 10, hypertrophic scars in 10 and normal adult skin in 5. The hybridization was performed with 4% paraformaldehyde-fixed and wax-embedded sections to detect the Tenascin-C mRNA.
RESULTSThe Tenascin-C mRNA was negative in the normal adult epidermis and weakly located in the fibroblasts of the papillary dermis and the epidermal adnexa. In all of the 10 keloid specimens, the Tenascin-C mRNA was positive throughout the epidermis and widely distributed in the dermis included in the fibroblasts, endothelial cells and epidermal adnexa. In the specimens of the 3 hypertrophic scars,the Tenascin-C mRNA was also positive in the epidermis, but in the other 7 cases, it became negative. In the dermis of the hypertrophic scar,the Tenascin-C mRNA was weaker than that in the keloid, but stronger than that in the normal skin.
CONCLUSIONSThe expression of Tenascin-C mRNA is markedly enhanced in the keloids.

OBJECTIVETo investigate of antiatherogenic effect and possible mechanisms of piper longuminine.
METHODThe atherosclerotic model was established by the hypercholesterol feeding rabbits. Male Mew Zealand rabbits were randomly divided into five groups: normal group, model group, the high-dose (5 mg x kg(-1) x d(-1)) and low-dose (2.5 mg x kg(-1) x d(-1) group of piperlonguminine, and simvastatin group (5 mg x kg(-1) x d(-1)). All the rabbits were fed for 60 days. Blood samples were taken from the ear edge vein of rabbits in the day before the experiment, and in the days of 20, 40 and 60 days after the experiment, respectively. All the rabbits were fasted for at least twelve hours before the blood was taken. The blood serum were analyzed for total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C). The blood serum of the 60th day were also analyzed for superoxide dismutase (SOD), malondialdehyde (MDA) and nitric oxide (NO). At last, the pathological observation of aorta and heart samples were carried out.
RESULTCompared with those in model group, the TC, TG and LDL-C levels were reduced (P < 0.05) and the HDL-C was raised in the piperlonguminine group; also, the serum SOD and NO level was raised (P < 0.05), MDA level was reduced in the piperlonguminine group (P < 0.05). Area percentage of aorta plaque was reduced (P < 0.01) in the piperlonguminine group. The aorta and heart injury was abated and coronary artery angusty extent was markedly abatement (P < 0.01). The results of observation through transmission electron microscope (TEM) indicated that the fine structure of aortal pathological degree was markedly abated.
CONCLUSIONThe piperlonguminine could inhibit the atherogenesis formation and development, which might be due to regulating the lipid metabolism and enhancing the antioxidation.

1H NMR metabonomics approach was used to reveal the chemical difference of urine between patients with Xiao-Chaihu Tang syndrome (XCHTS) and healthy participants (HP). The partial least square method was used to establish a model to distinguish the patients with Xiao-Chaihu-Tang syndrome from the healthy controls. Thirty-four endogenous metabolites were identified in the 1H NMR spectrum, and orthogonal partial least squares discriminant analysis showed the urine of patients with Xiao-Chaihu Tang syndrome and healthy participants could be separated clearly. It is indicated that the metabolic profiling of patients with Xiao-Chaihu Tang syndrome was changed obviously. Fifteen metabolites were found by S-pot of OPLS-DA and VIP value. The contents of leucine, formic acid, glycine, hippuric acid and uracil increased in the urine of patients, while threonine, 2-hydroxyisobutyrate, acetamide, 2-oxoglutarate, citric acid, dimethylamine, malonic acid, betaine, trimethylamine oxide, phenylacetyl glycine, and uridine decreased. These metabolites involve the intestinal microbial balance, energy metabolism and amino acid metabolism pathways, which is related with the major symptom of Xiao-Chaihu Tang syndrome. The patients with Xiao-Chaihu Tang syndrome could be identified and predicted correctly using the established partial least squares model. This study could be served as the basis for the accurate diagnostic and reasonable administration of Xiao-Chaihu-Tang syndrome.

OBJECTIVETo study the characteristics of dermal mesenchymal stem cells (DMSC), and explore whether they could enhance hematopoiesis recovery in vivo as well as facilitate proliferation and differentiation of hematopoietic cells in vitro.
METHODSMultipotential stem cells from the murine dermal mesenchyme were dissociated and cultured as donor cells. After 2 approximately 3 passages, the growth status, cell cycle, immunophenotype and morphology of DMSC were analyzed. Hematopoietic cells were plated onto a feeder layer formed by DMSC, cell count and CFU-GM yields were observed dynamically. Female mice received 5 Gy (137)Cs radiation were injected with DMSC cultured for 2 - 3 passages via tail vein. Cell count and CFU-GM yields of the bone marrow were observed regularly. Pathological study of the liver, spleen and bone marrow was done to evaluate hematopoiesis recovery.
RESULTSMurine DMSC are adherent cells with a morphology of fibroblastoid and spindle and multiangle in shape. Immunophenotypes showed that CD(45), CD(34), HL-DR positive DMSC were 1 - 3%, CD(44) and CD(13) positive DMSC 75 approximately 95%. Cell cycle assay demonstrated 83% of DMSC being G(0)/G(1) phase. In vitro, the total cell count and CFU-GM yields in the experimental group were higher than those of the long-term culture bone marrow cells by the third week. The DMSC can sufficiently support the proliferation and differentiation of hematopoietic cells for seven weeks. In vivo, peripheral granulocytic count, cells in the bone marrow of one femoral bone and CFU-GM by the third week in the experimental group were much higher than those of controls. Genetic assay of the murine blood demonstrated Y chromosome.
CONCLUSIONThe DMSC have characteristics of stem cells. DMSC sped up hematopoiesis recovery of irradiated mice. DMSC as a feeder layer can support proliferation and differentiation of hematopoietic cells.

OBJECTIVETo explore the hematopoietic reconstitution potential of mesenchymal derived stem like cells.
METHODSWe transplanted bone marrow mesenchymal derived stem like cells into lethally irradiated BALB/c mice. Hematopoietic cells were derived from the non-adherent bone marrow cells 24 hours after initial culture while murine mesenchymal derived stem like cells from bone marrow of donor mice were cultured for 10 days before the transplantation.
RESULTSAll mice of group 1 and 3 died in 7-8 days post irradiation following transplantation, while all the mice from group 2 and 4 survived. The time course of hematopoietic reconstitution was then observed. The peripheral blood and bone marrow cell count recovered in the MSC + G-CSF transplanted group and the BM transplanted group after 3 weeks. Interestingly, CFU-GM number in the MSC + G-CSF transplanted group increased significantly after 2 weeks and even more than that in the BM transplanted group after 3 weeks while as CFU-GM colony dropped 2 weeks after in the BM transplanted group. Spleen colony (CFU-S) number and size of the MSC + G-CSF transplanted group was significantly greater than the BM transplanted group. Furthermore, PCR analysis was performed using peripheral blood cells to determine if any male-derived cells were present. No male-derived cells were found in any of the mice from group 1 and 3. Y-chromosome-specific src gene was found to be dominant in the MSC + G-CSF transplanted group and the BM transplanted group by week 4 post transplantation. In addition, we demonstrated that induction with G-CSF lead to CFU-GM colony formation from MSC compartment in vitro.
CONCLUSIONThese results indicate that under stimulation of G-CSF, mesenchymal derived stem like cells might differentiate into hematopoietic primitive stem cells in vivo and have the capacity to re-establish hematopoiesis in lethally irradiated mice. This study should provide an alternative transplantation treatment for malignancy.

Rosai-Dorfman disease is a rare, idiopathic, benign, and self-limiting histiocytic proliferative disorder. A 26-year-old man presented with a single massive cutaneous nodule (reaching 30 cm in diameter) on the left shoulder and back for 15 months. The routine hematological and biochemical tests were normal. Magnetic resonance scanning showed the lesion involved the skin, subcutaneous tissue, and subjacent muscle group, accompanied by obvious lymph node enlargement in the left part of the neck, supraclavicular fossa, and axillary fossa. The histopathology of the left cervical lymph node revealed diffuse effacement of the normal nodal architecture, with patchy chronic inflammatory cell infiltrates comprising lymphocytes and sheets of histiocytes. Some histiocytes contained lymphocytes within their pale cytoplasm. Many multinucleated giant cells were found; however, caseating granulomas were not seen. The skin and muscle biopsy specimen obtained from the back revealed infiltrating lymphocytes and histiocytes diffusely distributed in the dermis, subcutaneous tissue, and crevices of the muscle fibers. The phenomenon of emperipolesis and the presence of multinucleated giant cells were also seen. Immunohistochemical staining revealed that the histiocytes were positive for S-100 protein and CD68 but negative for CD1a. Immunophenotyping of the infiltrating lymphocytes indicated positive reactions to CD3, CD45RO, CD5, CD7, CD4, CD8 (partly), CD79a, CD20 (partly), and Ki-67 (<1%). The final diagnosis was Rosai-Dorfman disease. Owing to the extensive and deep involvement of the subcutaneous tissue and muscles, the patient did not undergo surgery to excise the massive skin nodule. The lesion showed no obvious change at the 12-month follow-up.

OBJECTIVETo study the effect of Triptolide (TL) on the growth of prostate carcinoma cell line, and analyze its function and mechanism in anti-prostate cancer.
METHODSMTT experiments were performed to examine the inhibiting effect of TL on the proliferation of RM-1 cells, cell morphological changes observed by acridine staining, cellular cycles and apoptosis peak analyzed by flow cytometry, the apoptosis fracture zone investigated with DNA electrophoresis, and the expressions of caspase-3 and bcl-2 mRNA in RM-1 cells examined by RT-PCR.
RESULTSThe results of MTT experiments showed that after the treatment of TL (5, 10, 20, 40 and 80 ng/ml), the RM-1 cell proliferation inhibition rates were 9.8%, 25.1%, 39.2%, 48.8% and 53.2% respectively; 12, 24, 36 and 48 hours after the treatment of TL (10 and 20 ng/ml), the cell proliferation inhibition rates were 8.4%, 25.1%, 36.1%, 42.4% and 10.2%, 39.2%, 50.2% and 58.5% respectively. Acridine staining after the TL treatment revealed nucleus condensation, cell membrane invagination, irregular orange particles in the cells and apoptosis morphological changes; flow cytometry tests showed that 48 hours after the TL treatment (10, 20 ng/ml) of RM-1 cells, an obvious apoptosis peak appeared before the G1 stage; 24, 36 and 48 hours after it, DNA "trapezoid" strips could be seen; the caspase-3 mRNA expression in the TL treated cells was higher, and the bcl-2 mRNA expression was lower than in the controls.
CONCLUSIONTL can decrease bcl-2 expression, increase caspase-3 expression, induce apoptosis of prostate carcinoma cells, and consequently inhibit the proliferation of RM-1 cells in mice.
