Cyanobacteria are simple organisms which possess an endogenous circadian clock.Although the cyanobacterial clock has the same fundamental properties as circadian clocks in eukaryotes,its components are non-homologous to those of eukaryotes.The clock core of the cyanobacteria consists of the kai gene cluster and three Kai proteins KaiA,KaiB and KaiC,which the kai genes encode.The interactions among the Kai proteins modulate the phosphorylation state of KaiC,which generates circadian rhythm.The KaiC phosphorylation cycle constitutes the pacemaker of the cyanobacterial circadian rhythm.And signal transduction into and out of the clock core could occur via histidine protein kinase-based phosphorylation relays.

[Objective]To investigate the relationship of TCM syndrome patterns with gastrointestinal motility and hormones in functional dyspepsia (FD). [Methods] Among 30 cases of dyskinetic FD, 16 with liver depression and qi stagnation were allocated to Group B, 14 with spleen and stomach deficiency to Group C and 20 healthy volunteers served as control group ( Group A). Gastric evacuation, elctrogastrogram (EGG), serum motilin and migrating motor complex (MMC) wave of gastric antrum and duodenum during digestion were examined and analysed statistically. [Results]Gastric evacuation, contraction index and amplitude of phase II MMC wave, contraction amplitude and coordinated contraction of phase III MMC wave, and the main power of emptying EGG in empty stomach were decreased in Group B and Group C as compared with those in Group A,and those in Group C were lower than those in Group B, the differences being significant (P

Background The mitochondrial Na+/Ca2+exchanger, NCLX, plays an important role in the balance between Ca2+influx and efflux across the mitochondrial inner membrane in endothelial cells. Mitochondrial metabolism is likely to be affected by the activity of NCLX because Ca2+activates several enzymes of the Krebs cycle. It is currently believed that mitochondria are not only centers of energy produc-tion but are also important sites of reactive oxygen species (ROS) generation and nucleotide-binding oligomerization domain receptor 3 (NLRP3) inflammasome activation. Methods&Results This study focused on NCLX function, in rat aortic endothelial cells (RAECs), induced by glucose. First, we detected an increase in NCLX expression in the endothelia of rats with diabetes mellitus, which was induced by an injection of streptozotocin. Next, colocalization of NCLX expression and mitochondria was detected using confocal analysis. Suppression of NCLX expression, using an siRNA construct (siNCLX), enhanced mitochondrial Ca2+influx and blocked efflux induced by glucose. Un-expectedly, silencing of NCLX expression induced increased ROS generation and NLRP3 inflammasome activation. Conclusions These findings suggest that NCLX affects glucose-dependent mitochondrial Ca2+signaling, thereby regulating ROS generation and NLRP3 in-flammasome activation in high glucose conditions. In the early stages of high glucose stimulation, NCLX expression increases to compensate in order to self-protect mitochondrial maintenance, stability, and function in endothelial cells.

Acupoints are surface reaction and treatment spots under the pathological conditions which have functions of diagnosis and treatment. For the study of acupoints, we can carry it out from the aspects of structure and function. The two aspects have a close relationship. Structure is the material basis of function, while function is the manifesta-tion of structure. Therefore, the study of acupoints is not only significant to reveal the essence of acupoint, but also has enormous value in the guidance of acu-moxibustion for clinical practice. Staring from the normality of structure and variability of function, we explored the essence of acupoints, and further revealed ordered regulation rule and its biological basis, so that the essence of acupuncture points will be illustrated with scientific evidences.

Objective To explore the potential mechanisms of mesenchymal stem cell (MSC) therapy in ischemia/reperfusion injury (IRI)-induced acute kidney injury (AKI). Methods Forty-five C57/BL6 male mice were randomly divided into three groups: sham group, IRI group, and IRI+MSCs group, with 15 mice in each group. The IRI-induced AKI model in mice was reproduced by clamping both renal pedicles for 35 minutes. In the sham group, both kidneys were exposed, but their pedicles were not clamped. Six hours after reperfusion, mice in IRI+MSCs group received 100 μL of MSCs (1×104 /μL) isolated from the bone marrow from C57/BL6 mice via tail vein, while the mice in the IRI group received same amount of normal saline. Blood samples were harvested at 48 hours after reperfusion, and levels of serum creatinine (SCr) and blood urea nitrogen (BUN) were determined. The changes in renal pathology were observed by microscopy with PAS staining, and the tubular injury and acute tubular necrosis (ATN) scores were calculated. The number of leukocytes (CD45+) infiltrated in kidney at 24 hours and 72 hours after reperfusion was measured with flow cytometry. The number of neutrophils (Ly-6G+) and macrophages (F4/80+) infiltrated in kidneys at 24 hours and 72 hours after reperfusion was determined by immunofluorescence. Results There was significant increase in the related parameters in IRI group compared with those of sham group. The levels of SCr (μmol/L) and BUN (mmol/L) were 180.3±8.8 vs. 9.7±3.5, and 1 121.1±8.3 vs. 9.4±2.3, both P < 0.01. The score of tubular injury was 4.80±0.55 vs. 0 at 48 hours after reperfusion. The quantity of leukocyte (CD45+) infiltration in kidney at 24 hours and 72 hours after reperfusion was increased (×105 cells/g: 60.50±2.56 vs. 19.46±4.83, 42.00±1.87 vs. 14.70±3.74, both P < 0.01), and the number of neutrophils (Ly-6G+) and macrophages (F4/80+) infiltrated in kidney at 24 hours and 72 hours after reperfusion was also increase although the number of leukocytes infiltrated in kidney was significantly lower at 72 hours after reperfusion than that at 24 hours. There was significant lowering of the levels of SCr and BUN [SCr (μmol/L): 99.0±8.0 vs. 180.3±8.8, BUN (mmol/L): 84.5±7.6 vs. 112.1±8.3, both P < 0.01] in IRI+MSCs group, compared to IRI group. For the degree of tubular necrosis in two groups, the tubular injury scores were 2.60±0.55 vs. 4.80±0.55 (P < 0.05). The number of leukocytes infiltrated in kidney at 24 hours and 72 hours after reperfusion (×105 cells/g) were 24.20±4.53 vs. 60.50±2.56, 31.70±3.15 vs. 42.00±1.87 (both P < 0.01). The number of neutrophils was lowered despite (the number of macrophages was increased). However, the number of infiltrated leukocytes was significantly more in IRI+MSCs group at 72 hours than that at 24 hours (×105 cells/g: 31.70±3.15 vs. 24.20±4.53, P < 0.05). Conclusion MSCs could protect against IRI induced AKI by reducing the total number of leuckocytes, especially that of the neutrophils infiltrating into ischemic kidney and by recruiting macrophages into ischemic kidney.

Objective To screen and identify the colonic adaptation-related proteins.Methods Totally 20 SD rats were equally randomized into 2 groups:ultra-short bowel group (90％ of intestine was resected) and control group (transection and then anastomosis of the intestine).After 21 days of feeding,two-dimensional electrophoresis (2-DE) was performed to separate the total protein from the colon mucous epithelial tissues.Then Image Master 2D Platinum software was use to analyze differential expressional proteins,which were further analyzed by MALDI-TOF-MS and Mascot software to identify these proteins.Results The 2-DE patterns with high resolution were obtained from the colon mucous epithelial tissues of both groups.Four differentially expressed proteins were identified by MALDI-TOF-MS:M2-PK,AGR2,proteasome activator complex subunit 1,and pancreatic triacylglycerol lipase.These proteins were involved in sugar and fat metabolism and cell proliferation.Conclusion The identified proteins may play important roles in the process of colonic adaptation through substance metabolism and by stimulating cell proliferation.

Objective: The purpose of this study was to determine the relationship between TCM pattern and Hp infection and apoptosis of stomach mucosa in chronic gastritis, to discover the substance of TCM Pattern of chronic gasuitis on genetic molecular level and to establish syndrome differentiation system of chronic superficial gastritis on molecular level Methods: Get gastric mucosa tissue by electronic gastroscope. Hp infection, expression of Fas and bel-2 of 41 cases of incoordination between the liver and stomach group (IBLS group) and 50 cases of Dampness-beat in spleen and stomach(DHSS group) of chronic superficial gastritis were investigated by immunohistocbemistry examination, with 10 healthy persons as control group. Muti-factor non-condition logistic regression analysis was adopted to analyze the data. Results: The positive rate of HP was of 22%, 52% and 10% respectively in the IBLS group, the DHSS group and the control group. The positive rate of HP in the DHSS group was significant higher than in the IBLS and control group, showing there is a significant correlation between DHSS patern and HP infection. The expression rate of bcl-2 antigen was 24.2%, 76.0% and 30.0% respectively in the IBLS, DHSS and control group. The expression rate of bcl-2 antigen in the DHSS group was significant higher than in and the IBLS and control group(P＜0.01), showing there was significant correlation between DHSS pattern and expression rate of bcl-2 antigen(P＜0.01). The expression rate of Fas antigen was 70.7% and 46% respectively in the IBLS and DHSS group, the expression rate of Fas antigen in the IBLS group was significant higher than in DHSS group(P＜0.01), showing there was a significant correlation between IBLS pattern and expression rate of Fas antigen(P＜0.01).Conclusion: The result suggested that there was a certain relationship between HP infection and TCM pattern, the positive rates of HP was higher in DHSS pattern compared with the IBLS group. There was a certain relationship between the expression of bcl-2 and Fas in DHSS pattern, IBLS pattern may probably promoted apoptosis in gastritis, whereas HP infection performed as a main role in apoptosis in DHSS pattern. Bcl-2, liP and Fas might contribute to syndrome differentiation of chronic gastritis.

The effect of realgar nanoparticles (NPs) on endogenous small molecules in rat kidney was analyzed by mass spectrometry-based metabolomics.The relationship between the changes of metabolites and the nephrotoxicity of realgar NPs was also discussed to provide a basis for the further toxicity study and the clinical application of realgar NPs.SD rats were randomly divided into seven groups,including control group,three doses (40,200,1 000 mg/kg) of relegar and realgar NPs groups,respectly.After 28 days of continuous intragastric administration,all rats were sacrificed and their serum and kidney samples were collected.The toxic effect of realgar NPs on kidney tissues were examined by biochemical analysis and histopathologic examination,which revealed a dosedependent nephrotoxicity induced by realgar NPs.The LC-MS and GC-MS analysis were performed for the subsequent metabolomics study.A series of 32 metabolites were found to be altered significandy in the kindey of realgar NPs treated rats,and might serve as potential nephrotoxicity biomarkers.The results of metabolic pathway analysis indicated that the nephrotoxicity of realgar NPs might be associated with the disorders of the amino acids and phosphatidic acid metabolism.
