Objective To evaluate the feasibility of ETView visual endotracheal intubation in elderly patients with a potentially difficult airway under general anesthesia.Methods A total of 80 patients scheduled for elective surgery,with at least three characteristics indicative of an increased risk for difficult tracheal intubation and aged 65-86 years with American Society of Anesthesiologists (ASA) grade [Ⅱ or Ⅲ,were selected and randomly assigned into 2 groups:the control group (Group C) and the ETView visual endotracheal intubation group (Group E) (n=40 for each).After induction with propofol 0.5-1.5 mg/kg,sufentanil 0.2 μg/kg,and rocuronium 0.6mg/kg,regular tracheal intubation and ETView visual endotracheal intubation were conducted in Group C and Group E respectively.Blood pressure and heart rate were recorded before induction (T0),before initial intubation (T1),at successful intubation (T2),and 5min after successful intubation (T3).Duration of catheterization,number of intubation attempts,rate of successful intubation at first attempt and complications within 2 days of intubation were also recorded.Results The duration of catheterization and the number of intubation attempts were lower in Group E than in Group C[(34±6) s vs.(48± 22) s,(1.0±0.0) vs.(1.4±0.4),t=2.484 and 2.373,respectively,P=0.017 and 0.023,respectively].The rate of successful intubation at first attempt was higher in Group E than in GroupC (100％ or 40 cases vs.75％ or 30 cases),x2=5.714,P=0.017).There was no significant difference in hemodynamic changes and the rate of postoperative hoarseness between the two groups (P＞0.05 for both).Conclusions ETView visual endotracheal intubation shows excellent safety in elderly patients with a difficult airway under general anesthesia,with shorter catheterization duration and a higher rate of successful intubation at first attempt than regular intubation.

Objective To explore the effect of boiled fenugreek seeds on renal matrix metalloproteinase-2(MMP-2) activity in diabetic rats.Methods The model of diabetes was built with STZ in rats.The model rats were randomly divided into diabetes control groups (DM ) (n=10) and fenugreek seeds groups(FN) (n=10,and while normal control group (N) (n=10)rats was used.Diabetic rats were treated with fenugreek seeds for 12 weeks,the renal morphology and MMP-2 activity were observed in three groups .Results After diabetic rats were treated with fenugreek seeds for 12 weeks,optical microscopic examination indicated that the glomerular structure in N group was normal,the glomerular lesions in rats of DM groups were seriously and the pathologic changes of glomerular in rats of FN groups were alleviated significantly.Immunohistochemical results showed that the Col Ⅳ expression in glomerular ECM was increased in DM group compared with N group,and was decreased in FN group.The activity of MMP-2 was increased in FN group (1.41?0.18) compared with DM group (1.05?0.19) (P

OBJECTIVETo explore the methylation status in promoter region of norepinephrine transporter gene (NET, SLC6A2) in heart failure ( HF) patients and its correlation with qi deficiency/blood stasis syndrome (QDS/BSS).

METHODSThirty-six patients with heart failure (NYHA classification III to IV) were recruited in the study (as the heart failure group) and their scores of QDS/BSS were evaluated. Besides, a healthy elderly group (30 cases) and a healthy youth group (30 cases) were also set up. They were recruited from Physical Examination Center of Fujian Provincial Hospital. Pyrosequencing was applied to detect the methylation in promoter region of SLC6A2 gene, and the total methylation index (MTI) of CpG island was calculated. The correlation between the methylation status in promoter region of SLC6A2 and scores of QDS/BSS was assessed using Pearson and Partial analyses. Risk factors were screened and adjusted using Logistic regression.

RESULTSBy one-factor analysis of variance, the total MTI in the HF group (219.72% ± 54.03%) was obviously higher than that in the healthy elderly group (194.47% ± 34.92%) and the healthy youth group (161.60% ± 41.11%) (all P < 0.05). Meanwhile, the total MTI was higher in the healthy elderly group than in the healthy youth group (P < 0.01). By covariance analysis , after controlling age and BMI, the total MTI was higher in the HF group than in the healthy elderly group (P = 0.041), while it was higher in the healthy elderly group than in the healthy youth group (P = 0.016). Age was found to play an essential role in affecting MTI of SLC6A2 gene promoter region among the 3 groups (F = 16.447, P = 0.01). The total MTI was quite lower in the healthy youth group. Results of Partial correlation analysis showed MTI was positively correlated with scores of qi deficiency and blood stasis respectively (r = 0.494 and 0.419 respectively, both P < 0.05). Logistic regression analysis showed after adjusting confounding factors, the relative risk (OR value) of total MTI of SLC6A2 gene in promoter region was 1.038 (95% CI, 1.006 to 1.071, P = 0.020).

CONCLUSIONSAbnormally elevated methylation of the promoter region of SLC6A2 gene is one of risk factors for HF. In addition, the degree of methylation of the promoter region of SLC6A2 gene was positively correlated with the severity of QDS/BSS.

Objective To compare the mid-term clinical results of primary implantation of a selfexpanding nitinol stent and primary percutaneous transluminal angioplasty (PTA) for long range arteriosclerosis obliterans of the superficial femoral artery. Methods From December 2005 to February 2007,109 patients who had moderate-severe claudication or chronic limb ischemia (CLI)due to stenosis or occlusion of the superficial femoral artery were treated by endovascular technology. 53 patients (73 limbs) were treated by primary stenting and 56 patients (76 limbs)by PTA. We compared the clinical data of stenting group and PTA group at 6,12 and 24 months. Results The mean length of the treated segment was (16± 8)cm in the stenting group and(15±7)cm in the PTA group. At 6 months, the rate of restenosis on duplex ultrasonography was 13.7% in stenting group and 30.2% in PTA group (X2=4.09, P<0.05);at 12 months the restenosis rates were 25.5% in stenting group and 46.9% in PTA group(X2=4.75, P<0.05);at 24 months the restenosis rates on duplex ultrasonography were 38.1% in stenting group and 65.9% in PTA group(X2=6.66, P<0.01). Rutherford stages in stenting group were significantly better than those in PTA group. Conclusion In the mid-term, primary implantation of a self-expanding nitinol stent yielded results that were superior to those with PTA for arteriosclerosis obliterans or long range stenosis of the superficial femoral artery.

Objective To discuss the changes of correlative ultrasonic parameter index of normal hips and abnormal hips with developmental dislocation of the hip (DDH) in infants of different months in order to provide objective information for the diagnosis. Methods Three-hundred and seventy-eight normal hips and 244 hips with DDH among 622 hips of 311 infants were detected by ultrasonography(US). The morphology and structure information of hips were observed, and the values of ultrasonic parameter index,including angle α,angle 3, acetabular index( AI), femoral head percentage of cover(FHC) of normal hips and abnormal hips were measured. The values of each parameter index were collected by being divided into different groups (3 months a group) ,then the correlation was analyzed. Results Morphology and structure,position relation between femoral head and acetabulum of the hips were demonstrated by US. Normal or abnormal hips,the degrees of abnormal hips and the types of hips could be judged according to the findingsof US. Analysis of values of parameter index of normal hips:①There was significantly statistical significance in the values of ultrasonic parameter index, such as angle α, angle β, AI, FHC of normal hip between the groups of different age (P＜0.01). ②There was correlation between the age and the values of each parameter index, among which angle α, FHC had positive correlations with age ( r = 0. 537, 0. 554,respectively ) while angle β and Al negative correlations ( r = -0. 465, -0.424, respectively ). ③There was correlation between the values of different parameter index. Both angle β and AI had negative correlation with angle α,among which the latter correlation was closely ( r = - 0. 794). No statistical significance was found between the ultrasonic values of each group under different ages of different type abnormal hips( P ＞0.05) ,but closely negative correlations still existed between angle α and AI. ConclusionsUS can be viewed as an early definite and a screening method of diagnosing DDH.For older infants (above 6 months) it will be more accurate to analyze the ultrasonic parameter index together with the age of infants.
