Objective To investigate the treatment efficacy of lumbar spondylolisthesis patients with modic change. Methods The da-ta of 45 lumbar spondylolisthesis patients with modic change were analyzed retrospectively,which were admitted into hospital from January 2010 to December 2013 and received posterior lumbar interbody fusion ( PLIF) surgery. Those patients were tested by X-ray and Magnetic resonance imaging ( MRI) and confirmed the type of spondylolisthesis and Modic change. Based on the degree of spondylolysis and whether combined or not with Modic change,all the patients were divided into six groups:group A with Ⅱ grade spondylolisthesis;group B with Ⅲgrade spondylolisthesis;group C with Ⅱ grade spondylolisthesis with Modic typeⅠ;group D withⅡgrade spondylolisthesis with Modic typeⅡ;group E with Ⅲ grade spondylolisthesis with Modic type Ⅰ;group F with Ⅲ grade spondylolisthesis with Modic type Ⅱ. Those patients were evaluated preoperatively and postoperatively the scores according to the Visual Analogue Scale ( VAS) and Oswestry Disability Index ( ODI) systems,the obtained data were statistically analyzed and then were used to evaluated the treatment efficacy. Results The treatment efficacy of those patients were evaluated by follow-up work based on the scores of VAS and ODI systems,the results indicated that all those patients were improved in the scores of pain and ODI at different agrees. Within groups,the scores of low back and leg pain in VAS system and ODI preoperative were all significantly lower than that of postoperative (P<0. 0001). However,there were no significant differences of those scores among groups (P>0. 05). Conclusion Those spondylolisthesis patients with Modic change could obtained satisfactory clinical efficacy after posterior lumbar interbody fusion ( PLIF) surgery.

40/h) and non-severe group(n=15,AHI 5-40/h).Anthropometric measurements,fasting plasma glucose,insulin,blood fat,and CT quantitative measurement of abdominal adipose tissue were recorded. Results Insulin resistance index(HOMA-IR) in patients with OSAS was related to hypoxia independently of obesity variables.The severe group was characterized by more serious metabolic disorders and higher prevalence of metabolic syndrome than the non-severe group.OSAS was positively associated with an increased metabolic disorders risk for the severe group versus the non-severe group(OR=8.8).Using the receiver operating characteristic(ROC) curve analysis,waist circumference had the greatest areas under the ROC curves compared with body mass index and neck circumference.The results of multiple stepwise regression of lowest pulse oxygen saturation(LSpO2)during overnight sleep indicated that neck circumference followed by epworth sleepiness score(ESS) entered the equation(P

Objective To evaluate the effect of sevoflurane on the expression of α7 nicotinic acetylcholine receptor (α7nAChR) in hippocampal neurons of rats.Methods Forty-eight pathogen-free healthy adult Sprague-Dawley rats of both sexes,weighing 210-280 g,aged 3-4 months,were divided into 4 groups (n=12 each) using a random number table:control group (group C) and 1%,3% and 5% sevoflurane groups (S1,S2 and S3 groups).In S1,S2 and S3 groups,1%,3% and 5% sevoflurane were inhaled for 1 h,respectively.Morris water maze test was performed at 1 and 7 days after anesthesia to assess the cognitive function.Six rats in each group were sacrificed after the end of the test.The brains were then removed and the hippocampi were isolated for detection of the expression of α7nAChR (by Western blot) and contents of tumor necrosis factor-alpha and interleukin-1 (by enzyme-linked immunosorbent assay).Results Compared with group C,the number of crossing the platform was significantly decreased at 1 and 7 days after anesthesia in group S1,the time of staying at the target quadrant was significantly shortened,the number of crossing the platform was decreased,and the rate of time of staying at the original platform quadrant and rate of swimming distance at the original platform quadrant were decreased at 1 and 7 days after anesthesia in S2 and S3 groups,and the contents of tumor necrosis factor-alpha and interleukin-1 were significantly increased,and the expression of α7nAChR was down-regulated at 1 and 7 days after anesthesia in S1,S2 and S3 groups (P<0.05).Compared with group S1,the expression of α7nAChR was significantly down-regulated at 1 and 7 days after anesthesia in S2 and S3 groups (P<0.05).Compared with group S2,the expression of α7nAChR was significantly down-regulated at 1 day after anesthesia in group S3 (P<0.05).There was no significant difference in each parameter of Morris water maze test among group S1,group S2 and group S3 (P>0.05).Conclusion The mechanism by which sevoflurane induces inflammatory responses in hippocampi is related to down-regulation of α7nAChR expression in hippocampal neurons of rats.

Objective To explore the feasibility of quantitative assessment of pancreatic perfusion using dynamic contrastenhanced MRI (DCE-MRI).Methods Totally 68 healthy volunteers were divided into youth,middle and old groups according to ages.All volunteers underwent pancreas DCE-MRI examination.Images were transmitted to Research-DCE MRI Tool workstation to calculate the quantitative parameters,including volume transfer constant (Ktrans),interstitium-toplasma rate constant (Kep),interstitial volume (Ve) and plasma volume (Vp).Independent sample t test and one-way ANOVA test were used to evaluate the differences of pancreatic perfusion.Results There were no significant differences of Ktrans,Kep, Ve and Vp between male and female;Ve in old group was higher than that in youth and middle groups (P =0.036,0.001);Vp of pancreatic head was higher than that of pancreatic body and tail (P=0.011,0.023).Conclusion DCE-MRI can be applied to provide a reliable quantitative assessment of pancreatic perfusion noninvasively.The parameters of DCE-MRI of pancreatic perfusion are independent of gender but vary with age and pancreatic sites.

The natriuretic peptide(NP) system is an endocrine system that maintains fluid and pressure homeostasis by modulating cardiac and renal function.NP levels are elevated in patients with heart failure(HF) and other cardiac diseases.They are early warning system to help to identify patients at high risk for cardiac events.Measurement of NPs may be used to aid diagnosis and prognosis.NPs also can exert important anti-proliferative,anti-fibrotic effects to prevent the remodification in the heart with myocardial infarction and advanced HF.Brain natriuretic peptide is an important biomarker in patients with HF and other cardiovascular diseases,such as pulmonary hypertension and atherosclerotic vascular disease.In addition,synthetic NPs such as nesiritide could be used to treat the patients with acutely congestive HF. These Recombinant drugs are also being investigated for myocardial and renal protection in the setting of cardiac surgery and for prevention of cardiac remodeling.

OBJECTIVEThe aim of this study was to evaluate the efficacy and safety of combination therapy with simvastatin and fenofibrate in patients with combined hyperlipidemia.

METHODSA total of 221 patients with combined hyperlipidemia were randomly assigned to receive 10 mg simvastatin (n = 72) or 200 mg fenofibrate (n = 68), or a combination of 10 mg simvastatin + 200 mg fenofibrate (n = 81) for 6 months. Lipid profiles, physical and laboratory investigations for adverse effects were assessed.

RESULTS(1) Combination treatment were more effective in normalizing lipid profile than any monotherapy. Serum TC, LDL-C, and TG were reduced by 30%, 37% and 56% respectively, whilst HDL-C significantly increased by 24% (all P < 0.01). The improvement in TG and HDL-C achieved by combination treatment was superior to fenofibrate or simvastatin alone. (2) The success rate of TC, LDL-C and TG control in the combination therapy group were 51%, 55% and 61% respectively, with an overall success rate (all three together) of 45%, which was superior to either drug given as monotherapy. (3) All treatments were well tolerated with no increase in adverse events for combination therapy versus monotherapy.

CONCLUSIONThe results of this study demonstrated that combination therapy with fenofibrate (200 mg/day) and low-dose simvastatin (10 mg/day) is more effective than monotherapy in patients with combined hyperlipidemia, and is generally safe and well tolerated.
