Transient receptor potential (TRP) is a kind of novel Ca2+ permeant channel.It is later found that TRP channels are expressed broadly in many organisms,tissues and cell types.It is involved in the regulation of sensory conduction and cell signal transduction.Further studies are required to assess which TRPC6(a member of TRPC subfamily) is associated with the cytosolic Ca2+ levels,development and progression of cancer and tumor cell cycle.TRPC6 may be regarded as new targets for the treatment of cancer.

Objective To observe the effects of hypoxia preconditioning on the mitochondria ultrastructure of hepatocyte during liver transplantation in rats.Methods A modified orthopotic liver autotransplantation model was used to simulate liver transplantatation.Seventy two Sprague-Dawley rats were randomly divided into the following three groups:the normal control(group NC),the autotransplantation group(group AT),and the hypoxia preconditioning group(group HP),with twenty four rats in each group.Group HP were given an 8% oxygen atmosphere for 90 minutes before the operation.At 1,6,and 24 hours after the operation,the rats were killed and the following tests were conducted:1.The morphology of mitochondria was observed under transmission electron microscopy(TEM);2.Mitochondria were quantitatively analyzed by a MiVnt image analysis system.ResultsHepatic cells in group AT showed typical injury signs under TEM,the appearance of hepatocytes and mitochondria in group HP were much better than the group AT,and the areas,perimeters and diameters of mitochondria in group HP were much smaller than those in group AT by a significantly amount(P

Objective To investigate the role of tyrosine kinase Src in a murine C.albicans infection model. Methods Observed cell proliferation by alarmarblue assay at 2, 24 and 48 h after Src inhibitor PP2 treatment. Phagocytosis was determined by a fluorometric assay. Cytokine TNF-αand IL-10 production was detected by ELISA. Results The 0~33.3 μmol/L PP2 had no effect on cell proliferation after PP2 treatment for 2 h. When the PP2 treatment extended to 24 or 48 h, PP2 (11.1, 33.3μmol/L) showed significant inhibition on cell proliferation with 78%, 9%, and 54%,13%, respectively. At 48 h after 11.1μmol/L PP2 treatment, the internalization of C.albicans in macrophage is significantly inhibited, contributing to the inhibition of cell proliferation. However, the 11.1 and 33.3μmol/L PP2 significantly inhibited the cytokine TNF-αand IL-10 production during C.albicans infection (P<0.01). Conclusion Src kinase played an important role during C.albicans infection, especially for the cytokine TNF-αand IL-10 production.

Objective To investigate the causes of reduced function of neutrophils in neonates by measuring superoxide, one of the reactive oxygen species, produced by neutrophils following live bacterial phagocytosis in the whole blood. Methods Twenty-three cord blood samples were collected from normal full-term newborns and cultured with live Staphylococcus aureus and Escherichia coli. Blood cells were stained with Hydroethidine, an indicator of superoxide. The intensity of the superoxide of neutrophils were analyzed by flow cytometry. Fifteen adult blood samples were collected as control. Plasma replacement was used to study the function of body fluid in active oxygen metabolism of neutrophils. Results Most full-term neonatal neutrophils (PMNs) could produce superoxide anion following bacterial phagocytosis in the blood as that in adults. The level of superoxide production of term neonatal neutrophils, after stimulation of S. aureus, was as high as the adult′s but was significantly lower after stimulation by E. coli (bacteria cell ratio 40∶1, MFI 347?70 vs 461?55, P

OBJECTIVETo investigate the correlation between the pathogeneses of diarrhea-pre- dominant irritable bowel syndrome (D-IBS) complicated functional dyspepsia (FD) patients of Gan-stagnation Pi-deficiency Syndrome (GSPDS) and symptoms, psychological states, and gastrointestinal hormones.

METHODSA total of 111 patients with confirmed D-IBS complicated FD of GSPDS were recruited as the treated group by using Rome III standard and Chinese medical syndrome standard. And 30 healthy volunteers were recruited as the control group. The general condition, scoring for digestive symptoms, and the distribution of GSPDS subtype of all subjects were recorded by a questionnaire, and assessed by Symptom Checklist (SCL-90; a software for psychological test developed by Beijing Huicheng Adult Cor- poration). Meanwhile, plasma levels of 5-hydroxytryptamine (5-HT), somatostatin (SS), vasoactive intestinal peptide (VIP), endothelin (ET), interleukin 10 (IL-10), and interleukin 12 (IL-12) were measured in all subjects.

RESULTS(1) The subtype of D-IBS complicated FD of GSPDS was dominant in Pi-qi deficiency type (51/111,45.9%),Pi yang deficiency type (34/111,30.6%), and GSPDS. There was no statistical difference in the scoring of digestive symptoms among the 3 subtypes (P >0.05). (2) Compared with the control group, the anxiety factor score and the total score significantly increased in all three subtypes of D-IBS complicated FD of GSPDS, and the depression score of Pi yang deficiency type and Gan-depression type also significantly increased (P <0.05, P <0.01); the depression score of Gan-depression type was significantly higher than that of the Pi-qi deficiency type (P <0.01). Plasma 5-HT levels were obviously lower in D-IBS complicated FD patients of GSPDS accompanied with anxiety or depression than in those with no obvious psychological abnormalities, and VIP and IL-10 levels were significantly lower than those in the control group (P <0.05). Plasma VIP levels were also obviously lower in D-IBS complicated FD patients of GSPDS accompanied with anxiety or depression than in those with no obvious psychological abnormalities (P <0.01), and SS levels were significantly lower than those in the control group (P <0.05). There was no statistical difference in plasma ET or IL-12 levels in each patient group, when compared with the control group (P >0.05). (3) Compared with the.control group, plasma 5-HT levels significantly increased, plasma VIP and IL-10 levels significantly decreased in ach subtype of D-IBS complicated FD patients of GSPDS (P <0.05, P <0.01), and no significant change of SS, ET, or IL-12 occurred (P >0.05). Besides, plasma 5-HT levels were significantly higher in Gan-depression type than in Pi yang deficiency type, VIP levels were lower in Gan-depression type than in Pi-qi deficiency type (all P <0.05).

CONCLUSIONSGan stagnation and Pi deficiency were dominant in D-IBS complicated FD patients of GSPDS. Psychological abnormalities, increased plasma 5-HT levels, and decreased plasma VIP levels were closely correlated with Gan stagnation subtype, which provided some reference for looking for objective indicators of Chinese medical syndromes in treating D-IBS complicated FD patients of GSPDS.

Galanin is a peptide with wide-ranging effects,especially within the central,peripheral nervous system and endocrine system.Many tumors of neuroendocrine origin,and also an increasing number of non-neuroendocrine cancers,have been shown to express galanin and/or its receptors.Expression of galanin peptide has been detected in pheochromocytoma,squamous cell carcinoma,pituitary adenoma,gastrointestinal cancers and so on.Galanin peptide plays an important role in tumori-genesis and progression of many kinds of tumors.Therefore,studying the roles of galanin and its receptors are helpful for diagnosis and treatment of tumors.

Wogonin is a kind of natural flavonoid compound. According to findings in the latest studies, wogonin shows a wide range of antitumor effects, with the characteristics of multi-pathway, multi-link and multi-target, such as promoting tumor cell apoptosis through ROS or Ca(2+)-mediated signal paths, enhancing tumor cytotoxicity by TNF-α and TRAIL, blocking tumor cell cycle, inhibiting tumor angiogenesis and resisting cancer synergistically with chemotherapeutic drugs. Moreover, Wogonin could enhance body immune function by enhancing immune cell infiltration, regulating the immune cell phenotype and promoting relevant cytokine secretion. In this paper, the authors summarized the advance in studies on wogonin's antitumor and immunomodulatory effects.
