Chinese Journal of Tissue Engineering Research 2015;19(16):2593-2597
BACKGROUND:In recent years, commonly used removable partial denture materials include Vitalium200 material, cobalt-chromium aloys and titanium materials. OBJECTIVE:To explore the value of different removable partial dentures in the repair of dentition defects. METHODS: Ninety cases of dentition defects, including 45 males and 45 females, aged 20-57 years old, were subject to removable partial denture repair. Among them, 30 cases were treated with Vitalium2000 removable partial dentures, 30 cases with titanium removable partial dentures, and 30 cases with cobalt-chromium removable partial denture. Denture inplace rate, incidence rates of denture stomatitis, periodontal disease and secondary caries, patient satisfaction self-evaluation were compared between three groups within 2 years after implantation. RESULTS AND CONCLUSION:Vitalium2000 material group was superior to pure titanium and cobalt-chromium aloy groups in the denture inplace rate, incidence rates of denture stomatitis, periodontal disease and secondary caries (P < 0.05). Patients in the Vitalium2000 material group were more satisfied with lightweight and comfort, aesthetics, chewing ability, odor degree of removable partial dentures than those in the other two groups (P < 0.05). These findings suggest that Vitalium2000 removable partial dentures can better improve the denture in place rate, reduce the incidence of denture stomatitis, periodontal disease and secondary caries, ensuring the comfort level and aesthetics of dentures.

HepG2 cells were pre-incubated with insulin (Ins 0,1,0. 1,0.01 μol/L) and dexamethasone ( Dex 0,3,0. 3,0.03 μol/L) alone or together for 24 h to induce insulin resistance (IR) in vitro, the resistant level was estimated by glucose consumption, the optimal model of insulin resitance was chosen, and at the same time its lasting time of resistance was determined. In order to investigate the effects and mechanisms of mifepristone on in sulin-resistant HepG2 cells induced by insulin and dexamethasone, mifepristone and pioglitazone were adminis tered 24 h after the optimal model of insulin-resistant HepG2 cells was established. The glucose consumption, in tracellular concentrations of glucose, glycogen, ATP, and free fatty acid (FFA) in each group were detected. The expression of InsR-mRNA and GR-mRNA was detected by semi-quantitative reverse transcription and polymerase chain reaction (SqRT-PCR). Results revealed that pretreatment with insulin (0. 1 μmol/L) and dexamethasone (0.3 (μol/L) for 24 h caused optimal insulin resistance of HepG2 cells which lasted for 36 h. Compared with control group, the glucose consumption, intracellular glucose, glycogen, ATP contents and the level of InsR-mRNA in model cells decreased while FFAs concentrations and GR-mRNA increased. However, the tendency of insulin resistant HepG2 cells was obviously attenuated by pioglitazone at the concentration of 0. 2 mmol/L and mifepris tone at 200μmol/L and 20 μol/L while mifepristone at 2 μol/L had no effect on insulin-resistant cells. The findings indicated that mifepristone at 200 μol/L and 20 μol/L improved the insulin resistance via modulating intracellular glucolipid metabolism and the expression of InsR-mRNA and GR-mRNA.

AIM: To investigate the role of infiltration of macrophages and expression of intracellular adhesion molecule-1 in the pathogenesis of oleic-acid-induced acute lung injury rats. METHODS: The rats were subjected to injection of oleic acid (oleic acid group) or saline solution (control). After injecting oleic acid or saline for 4 hours, the PaO 2 of the left heart, lung permeability index(LPI), the number of macrophage and the levels of soluble intercellular molecule-1 (sICAM-1) in the bronchial alveolar lavage fluid (BALF) were measured. The levels of expression of ICAM-1 mRNA were evaluated by in situ hybridization and the degree of macrophage infiltration and the expression of ICAM-1 were evaluated by double staining immunocytochemistry. RESULTS: The PaO 2 of the oleic acid group was significantly lower than that of the control group (P

AIM: To investigate the protective effect of anti-macrophage migration factor monoclonal antibody (anti-MIF MAb) on oleic-acid-induced acute lung injury (ALI) rats and its influence on the expression level of MIF and intercellular adhesion molecule-1(ICAM-1). METHODS: The rats were subjected to injection of oleic acid (oleic acid group) or saline solution (control group). One hours before administration of oleic acid, the rats were intraperitoneally injected with anti-MIF antibody (5 mg/kg) as the treatment group. After injecting oleic acid or saline for 4 hours, the PaO_2, lung permeability index (LPI), the number of macrophage and the level of soluble ICAM-1 (sICAM-1) in the bronchial alveolar lavage fluid (BALF) were measured. The expression level of MIF mRNA and ICAM-1 mRNA in the lung were detected by in situ hybridization, and the degree of macrophage infiltration and the expression of MIF were evaluated by double staining immunocytochemistry. RESULTS: The PaO_2 of the oleic acid group was far lower than those of the control and treatment group (P

OBJECTIVETo analyze and evaluate the clinical efficacy of heat-sensitive moxibustion for symptoms of large intestine cancer.
METHODSSixty patients with large intestine cancer were randomly divided into an observation group and a control group, 30 cases in each one. FOLFOX chemotherapy regimen was used in the two groups,and heat-sensitive moxibustion was added in the observation group. The acupoints were Zusanli(ST 36), Sanyinjiao (SP 6) Xuehai (SP 10) and Geshu (BL 17), etc. The treatment was applied once a day,five-day treatment as one course. Four courses were required. The reaction rates of uncomfortable symptoms by the Chinese version of the M. D. Anderson symptom inventory (MDASI-C) scale and clinical effects were analyzed and evaluated in the two groups.
RESULTSAfter treatment, the MDASI-C reaction rate of uncomfortable symptoms in the observation group was 50.4% which was lower than 53.3% in the control group (P < 0.05). The total effective rate of symptom improvement in the observation group was 83.3% (25/30), which was higher than 60.0% (18/30) in the control group (P < 0.05).
CONCLUSIONHeat-sensitive moxibustion can improve symptoms of chemotherapy for large intestine cancer.

Objective To evaluate the effect of remote limb ischemic postconditioning on the level of adiponectin during myocardial ischemia-reperfusion (I/R) in rats.Methods Fifty-seven male Sprague-Dawley rats,aged 8 weeks,weighing 250-350 g,were randomly divided into 3 groups (n =19 each):sham operation group (group S); group I/R; remote limb ischemic postconditioning group (group RLIP).Myocardial ischemia was induced by occlusion of anterior descending branch of left coronary artery for 30 min followed by 180 min reperfusion in urethane-anesthetized rats.In group S,the anterior descending branch was only exposed but not ligated.The animals underwent 10 min ischemia of bilateral hind limbs starting from 20 min of occlusion of the anterior descending branch,followed by reperfusion in RLIP group.The changes in S-T segment were recorded at 30,60,120 and 180 min of reperfusion.At 180 min of reperfusion,the blood samples were taken from the jugular vein for determination of serum levels of creatine kinase MB (CK-MB) and cardiac troponin Ⅰ (cTnⅠ).The animals were then sacrificed and hearts were removed for measurement of myocardial infarct size (IS) and adiponectin contents in myocardial tissues (by ELISA).Results Compared with group S,S-T segment was significantly elevated at each time point,myocardial IS,and serum cTnⅠ and CK-MB levels were increased,and adiponectin contents were decreased in I/R and RLIP groups.Compared with group I/R,elevation of S-T segment was significantly decreased at each time point,myocardial IS,and serum cTnⅠ and CK-MB levels were decreased,and adiponectin contents were increased in RLIP group.Conclusion The mechanism by which remote limb ischemic postconditioning reduces myocardial I/R injury is related to increased level of adiponectin in the myocardium of rats.
