Objective:To compare the surgery indicators of early lung cancer patients between video-assisted thoracoscopic surgery and thoracotomy in order to provide suggestion for surgery scheme.Methods: 126 early lung cancer patients, from March 2014 to January 2016 stayed in our hospital, were chosen as observation object. They were divided in control group (63 cases, thoracotomy) and observation group (63 cases, video-assisted thoracoscopic surgery), and to compare series of surgery indicators, IL-6 and TNF-α between the two groups.Results: The operating time and blood loss of observation group were lower, and the dissected lymph node number of observation group was higher than control group, respectively, and both of the differences were statistical significant (t=6.568,t=3.096, P<0.05;t=3.659,P<0.05); the hospital stay, catheter-retaining time and pain score of observation group were lower than control group, and the differences also were statistical significant (t=15.850,t=12.379,t=10.272;P<0.05); the differences of IL-6 and TNF-α between two groups were no statistical significant before treatment, and both of them reduced after treatment; both of the IL-6 and TNF-αof observation group were lower than control group (t=13.073, t=1.629;P<0.05); on the other hand, the total rate of complications of observation group, such as pneumonia, pulmonary atelectasis and arrhythmia, were higher than control group (x2=0.208, x2=2.800,x2=0.341;P<0.05). Conclusion: Early lung cancer patients are more suitable for video assisted thoracoscopic surgery, and its effect is better and is more conducive to the rehabilitation of patients after surgery.

AIM: To observe the effects of methionine-induced hyperhomocysteinemia on protein C(PC), antithrombin-Ⅲ (AT-Ⅲ) and von willebrand factor (vWF). METHODS:Eighteen New Zealand rabbits were randomized as methionine group (group M,n=9) and control(group C,n=9), which were fed with methionine-rich diet(600 mg/d) and regular diet respectively for sixteen weeks.By the end of sixteen weeks,the serum biochemistry and PC,AT-Ⅲ and vWF in plasma were determined and vWF expression of endothelial cells of aorta were examined.RESULTS:In group M, the levels of methionine(29.97?5.34 ?mol/L) and homocysteine(13.30?2.19 ?mol/L) in serum were signifficantly higher than those(14.48?1.97 ?mol/L and 5.36?1.19 ?mol/L, respectively,P

AIM: To observe the oxidative modification of low density lipoprotein iinduced by hyper homocysteinaemia following application of methionine. METHODS: Thirty two rabbits were randomized as group methionine(group M, n =9), group cholesterol (group Ch, n= 9), group methionin+cholesterol (group M+Ch, n= 9) and control group (group C, n= 5).In group M, Ch and M+Ch, the animals were fed with the food containing 3% methionine, 3.75% cholesterol and 3% methionine+3.75% cholesterol, respectively. By the end of sixteen weeks, the blood were taken and the measurements were carried out. RESULTS: Following application of methionine, the levels of hyperhomocysteine, ox-LDL and TBARS in group M and group M+Ch were significntly higher than those of group C and group Ch ( P

Objective To investigate the method of disinfection and sterilization of ventilator tubes and accessories in order to increase the sterilization quality of them. Methods 120 ventilator tubes and accessories from ICU and emergency department were randomly dividied into the control group,and the study group. Bacteriologic tests were conducted in the two groups. Results There was significat differ-ence in bacteriologic tests between the two groups. Conclusions It is necessary to research into steriliza-tion method of ventilator tubes and accessories.

Objective To evaluate the significance of myocardial bridge and find a reasonable diagnosis and treatment strategy.Methods Sixty-three myocardial bridge patients and sixty-three patients with negative results of coronary artery angiography were reviewed.The clinical data of symptoms,electrocardiogram,exercise tests,coronary artery angiography,therapeutics and the serum levels of C-reactive protein(CRP)were analyzed.Results The symptoms of chest distress and chest pain were found in myocardial bridge patients.Myocardial consumption of oxygen augmentation causes the symptoms of aggravation.Positive results of electrocardiogram and exercise tests in many of myocardial bridge patients were examined.There were no relationship with severity of myocardial bridge artery stenosis.Most of myocardial bridge were discovered in anterior descending branch.At present,the main treatment of myocardial bridge was drug therapeutics.After treatment,the serum levels of CRP was significantly decreased.Conclusion Myocardial bridge was anatomy abnormality with important clinical significance.The serum levels of CRP can be used to evalue the therapeutic efficacy of myocardial bridge.

OBJECTIVE To investigate the role of the complement C3/C3aR signaling pathway in the prefrontal cortex and colon neuroglia cell interactions during meth-amphetamine(METH)addiction,to observe the effects of TLR4 inhibitors as well as complement C3 elimination on METH reward and relapse behavior,and to explore the neuroinflammatory mechanisms of complement C3 acti-vation in METH addiction.METHODS ①A 14 d and 28 d rat METH addiction model was established to observe the effects of TLR4 antagonist ibudilast 3 mg·kg-1 and 10 mg·kg-1 on self-administration,reward motivation,relapse,and natural reward behavior in METH-trained 14 d rats and the effects of 0.02 mg·kg-1 complement C3 antago-nist on self-administration behavior in METH-trained 28 d rats.② Differences in the expression of TLR4,NF-κB,GRP94,C3,cathepsin L,CD68,and GFAP in the pre-frontal cortex of each group were examined using West-ern blotting.③ In addition,the expression of ATF6 in the prefrontal cortex of each group and the effects on neuro-nal and microglia/macrophage INOS,CD206 GRP94,and complement C3/C3aR.RESULTS ① Endoplasmic reticulum stress occurred in neurons and microglia after METH exposure depending on GRP94 and unfolded pro-tein responses to the ATF6 pathway.In addition,it acti-vates the TLR4-NF-κB pathway.② Microglia with high complement C3/C3aR expression in the prefrontal cortex were recruited to synaptic pruning and phagocytic responses around neurons with high GRP94,comple-ment C3/C3aR expression and these effects were blocked by complement C3 antagonists.③ In the rec-tum,GRP94 functions as a molecular chaperone for com-plement C3 and cathepsin L.Crosstalk occurs between enteric neurons high in GRP94,complement C3,and macrophages high in C3aR,located in the submucosa,lamina propria,and muscular,respectively,and all of these effects are blocked by complement C3 antago-nists.④ Treatment with the TLR4 antagonist ibudilast inhibits self-administration,reward motivation,and cue-or METH-priming in METH-trained 14 d rats,but fails to affect natural reward behavior.Ibudilast treatment attenu-ates the TLR4-NF-κB inflammatory pathway and comple-ments C3/C3aR pathway in the prefrontal cortex.CON-CLUSION Activation of the complement C3/C3aR signal-ing pathway by TLR4-NF-κB inflammatory signaling in the prefrontal cortex mediates the METH addiction pro-cess,providing an experimental basis for the clinical treatment of METH addiction,and targeting TLR4/NF-κB inflammatory signaling and complement C3/C3aR may be a new way to intervene in METH addiction.
