Objective To investigate the significance of MMP-9 and TIMP-1 test for assessing the occurrence and development of chronic heart failure.Methods One hundred and twenty-seven patients with chronic heart failure were enrolled in the observation group,and 40 cases community health people were selected for the control group. The levels of serum MMP-9 and TIMP-1 were detected and the LVEF and E/E ' were evaluated using endocardiography. Results Compared with the control group, the level of MMP-9 was significantly higher (<0.01) but the level of TIMP-1 had significantly decreased ( <0.05) in the observation group. And the ratio of MMP-9 and TIMP-1 had significantly increased compared with the control group ( <0.05) . There were statistically significant differences of LVEF and E/E' between the observation group and control group ( <0.05) . In the observation group,the level of MMP-9, MMP-9/TIMP-1,LVEF and E/E' were increased but the level of TIMP-1 decreased significantly in cases with cardiac functional class III compared with cardiac function class II (<0.05) . There were significant differences between the cases with class IV heart function and class II, III in the levels of MMP-9, TIMP-1 and MMP-9/TIMP-1 ( <0.05) . In the cases of class IV heart function, the LVEF and E/E' have significantly increased compared with the cases of class II ( <0.05) . MMP-9 + TIMP-1 +MMP-9/TIMP-1 combination has higher sensitivity and specificity than the MMP-9,TIMP-1 and MMP-9/TIMP-1 single indicator, and the joint diagnostic value of LVEF + E/E' was less than that of IL-18+ NT-ProBNP. Conclusion The levels of MMP-9 and TIMP-1 and their ratio may have contributed to the early detection and diagnosis for chronic heart failure,and help to determine the disease progression.

Objective To study the clinical efficacy of naloxone combined with edaravone on acute alcoholism. Methods One hundred and twenty-five patients with acute alcoholism were randomly divided into the control and treatment groups. The control group accepted conventional treatment and taking naloxone, while the treatment group accepted edaravone on the basis. Before and after treatment,the treatment recovery time,recovery respiratory rate time and symptom disappearance time were recorded. The malondialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH), neuron-specific enolase (NSE), S-100βand vascular cell adhesion points-1 (VCAM-1) were detected. Results After treatment,the recovery time and recovery respiratory rate time of the treatment group were significantly shorter than those of the control group ( <0.05) . In the control group, S-100β was significantly improved after treatment ( <0.05) . NSE, S-100β, VCAM-1 and MDA have significantly decreased ( <0.05) after treatment in the treatment group. Compared with the control group, there were significant differences of S-100β,VCAM-1 and MDA in the treatment group before and after treatment (<0.05) . While SOD and GSH have significantly increased ( <0.05) after treatment and showed significant differences compared with the control group ( <0.05) . Conclusion Naloxone and edaravone combination therapy can improve oxidative stress and nerve damage, which help early rehabilitation in patients with acute alcoholism.

Objective : To investigate the effect of different decontamination methods, including photodynamic therapy, sandblasting and titanium curette, on titanium surface morphology and bacterial adhesion for the treatment of peri-implant disease. Methods: Porphyromonas gingivalis (Pg) and Fusobacterium nucleatum (Fn) were inoculated on the surface of polished titanium specimens, and titanium specimen surfaces were treated with different decontamination methods after incubation. The titanium specimens were divided into a no-treatment control group, photodynamic group, sandblasting group and titanium curette group according to different decontamination methods. The changes in titanium surface roughness were observed by atomic force microscopy (AFM), and the remaining bacteria on the titanium surface were observed by scanning electron microscopy (SEM) and live/dead bacteria staining tests. After reinoculation of Pg and Fn, bacterial readhesion was observed on the surface of decontaminated titanium specimens. Results : The AFM results showed that the surface roughness of the titanium curette group was significantly higher than that of the no-treatment control group, photodynamic group and sandblasting group (P<0.05), and there was no statistically significant difference between the no-treatment control group, photodynamic group and sandblasting group (P>0.05). The results of contact angle measurement showed that the surface contact angle of each treatment group was smaller than that of the no-treatment control group (P<0.05). The SEM results obtained after the titanium specimen surface was decontaminated showed that the number of bacteria on the no-treatment control group surface was higher and the bacteria were relatively concentrated. The bacteria on the surface of the photodynamic group, sandblasting group and titanium curette group were scattered and distributed in small numbers, and most bacteria on the surface of the photodynamic group were ruptured. The results of the live/dead bacteria staining experiment showed that the percentage of dead bacteria on the surface of the photodynamic group was significantly higher than that of the no-treatment control group, sandblasting group and titanium curette group (P<0.05). The remaining bacteria on the surface of the sandblasting group and titanium curette groups were mainly live bacteria. The remaining bacterial adhesion on the surface was significantly reduced for the sandblasting group compared to the no-treatment control group and the photodynamic and titanium curette groups (P<0.05). SEM and live/dead bacteria staining results of bacterial readhesion on the surface of titanium specimens showed that there was an aggregation of Pg on the surface of the titanium curette group, and its surface bacterial adhesion was significantly higher than that of the no-treatment control group, photodynamic group and sandblasting group. Conclusion In mechanical decontamination, sandblasting machines are a better option than photodynamic therapy and titanium curettes; however, sandblasting does not remove all bacterial contamination. For sterilization, photodynamic therapy is more effective than sandblasting and titanium curettes. A combination of sandblasting and photodynamic therapy methods for the treatment of peri-implant disease may be considered in clinical practice.
