Objective: To compare the quantities of water-soluble, water-insoluble glucans synthesized by S. mutans in 3-4 years old children with high dmft and no caries. Methods: The quantities of water-soluble and water-insoluble glucans synthesized by S. mutans from dental plaques of children with high dmft (dmft≥5) and caries-free (dmft=0) were measured using the anthrone method. Results: S. mutans isolated from the children with high dmft had stronger ability in producing both water-soluble and water-insoluble glucans than those isolated from the caries-free children (0.0332 mg/ml v.s. 0.0192 mg/ml and 0.0357 mg/ml v.s. 0.0215 mg/ml respectively). Children with high dmft harbored more isolates with higher water-soluble or water-insoluble glucans producing ability than caries-free children. Water-insoluble glucans produced by all the clinical isolates is higher than water-soluble glucans (0.0301 mg/ml v.s. 0.0267 mg/ml) and the difference was statistically significant. Conclusion: There may be a correlation between the extracellular glucans producing ability of S. mutans and the caries susceptibility in deciduous teeth.

Study was carried on pentobarbital anesthetized cats to investi-gate the effect of clonidine on arrhythmias induced by coronary occlusion. Clonidine 15???g/kg iv 15min prior to ligation of left anterior descending coronary artery significantly reduced the frequenecy of arrhythmias: the ventricular premature bats ( phase Ia, VPB from 80% in controls to 20%,P

Rotundine (1 micromol L(-1)) was incubated with a panel of rCYP enzymes (1A2, 2C9, 2C19, 2D6 and 3A4) in vitro. The remained parent drug in incubates was quantitatively analyzed by an Agilent LC-MS. CYP2C19, 3A4 and 2D6 were identified to be the isoenzymes involved in the metabolism of rotundine. The individual contributions of CYP2C19, 3A4 and 2D6 to the rotundine metabolism were assessed using the method of total normalized rate to be 31.46%, 60.37% and 8.17%, respectively. The metabolites of rotundine in incubates were screened with ESI-MS at selected ion mode, and were further identified using MS2 spectra and precise molecular mass obtained from an Agilent LC/Q-TOF-MSMS, as well as MS(n) spectra of LC-iTrap-MS(n). The predominant metabolic pathway of rotundine in rCYP incubates was O-demethylation. A total 5 metabolites were identified including 4 isomerides of mono demethylated rotundine and one di-demethylated metabolite. The results also showed that CYP2C19, 2D6 and 3A4 mediated O-demethylation of methoxyl groups at different positions of rotundine. Furthermore, the ESI-MS cleavage patterns of rotundine and its metabolites were explored by using LC/Q-TOF-MSMS and LC/iTrap-MS(n) techniques.

Objective To investigate the effect of norcantharidin on growth inhibition and induction of apoptosis of human rectal cancer Colo 320 cells. Methods Norcantharidin (NCTD) in different concentrations were added to rectal cancer Colo 320 cells. Morphological characteristics of apoptosis were observed using the light microscope and transmission electron microscope. The expressions of Bag-1 and Bcl-2 proteins were tested by Western blotting. The growth inhibition of Colo 320 cells on the cell cycle was observed by flow cytometry. Results The apoptosis morphological changes of Colo 320 cells were observed by the light microscope and transmission electron microscopy. Flow cytometry analysis showed that the cell count of G2/M phase in experimental group was higher than that in control group ( <0.05) but the cell counts of G0/G1 and S phases have decreased in experimental group after treatment with NCTD at the concentrations of 5μg/mL, 10μg/mL and 20 μg/mL, and presented dosage dependence relations. The expressions of Bag-1 and Bcl-2 proteins have decreased. Conclusion Norcantharidin has inhibitory effect on rectal cancer Colo 320 cells, and the effect may be related to the cell cycle arrest and apoptosis.

The STandards for Reporting Interventions in Clinical Trials Of Moxibustion (STRICTOM), in the form of a checklist and descriptions of checklist items, were designed to improve reporting of moxibustion trials, and thereby facilitating their interpretation and replication. The STRICTOM checklist included 7 items and 16 sub-items. These set out reporting guidelines for the moxibustion rationale, details of moxibustion, treatment regimen, other components of treatment, treatment provider background, control and comparator interventions, and precaution measures. In addition, there were descriptions of each item and examples of good reporting. It is intended that the STRICTOM can be used in conjunction with the main CONSORT Statement, extensions for nonpharmacologic treatment and pragmatic trials, and thereby raise the quality of reporting of clinical trials of moxibustion. Further comments will be solicited from the experts of the CONSORT Group, the STRICTA Group, acupuncture and moxibustion societies, and clinical trial authors for optimizing the STRICTOM.

OBJECTIVETo investigate infection-related mortality (IRM) after allogeneic hematopoietic stem cell transplantation in patients with refractory/relapse acute leukemia.

METHODSWe conducted a retrospective analysis of 127 patients with refractory/relapse acute leukemia and investigated the incidence, causes and risk factors of IRM.

RESULTSSixty-seven of the patients died after the transplantation. The 5-year overall survival and disease-free survival was (35.2∓5.3)% and (30.8∓5.6)% among these patients, respectively. IRM occurred in 28.3% (36/127) of the patients. Multivariate analysis showed that grade II-IV acute graft-versus-host diseases (aGVDH, P=0.049, OR=3.017) and post-transplant invasive fungal infection (P=0.032, OR=3.223) were independent risk factors of IRM.

CONCLUSIONAs a common cause of transplant-related mortality, IRM is more frequent in cases of refractory/relapse acute leukemia than in cases with a standard risk profile, and effective prophylaxis and treatment of severe GVHD remain currently the primary measures for reducing post-transplant IRM.

PURPOSE: This study was aimed to investigate the effect of pseudolaric acid B (PAB) on proliferation, invasion and epithelial-to-mesenchymal transition (EMT) in pancreatic cancer cells and to explore the possible mechanism. MATERIALS AND METHODS: The pancreatic cancer cell line SW1990 was cultured and treated with PAB dose- and time-dependent manners. Cell proliferation and invasion ability were measured by MTT assay and Matrigel/Transwell test, respectively. Semi-quantitative real-time polymerase chain reaction and Western blotting were conducted to detect the expression of EMT markers and the key molecules. Finally, nude mice subcutaneous transplantation tumor model was used to confirm the therapy efficacy of PAB. RESULTS: PAB could inhibit SW1990 cell proliferation and invasion in time- and dose-dependent manners. Vimentin, fibronectin, N-cadherin, Snail, Slug, YAP, TEAD1, and Survivin were down-regulated (p < 0.01), while E-cadherin, caspase-9, MST1, and pYAP were up-regulated (p < 0.05). Combined PAB and gemcitabine treatment markedly restricted the tumor growth compared with gencitabin or PAB alone groups. CONCLUSION: PAB could inhibit the proliferation and invasion ability of pancreatic cancer cells through activating Hippo-YAP pathway and inhibiting the process of EMT.
