Objective To evalue the effects of elevation epidural block with 0.2% ropivacaine on lung function. Methods fifty ASA Ⅰ-Ⅱ patients undergoing elective radical mastectomy were anesthetized with method of epidural block .T 2-3 or T 3-4 were selected as puncture site. A catheter was inserted into the epidural space in a cephalad direction for 3-4cm. Nasal catheter oxygen inhalation was used in routine method. A loading dose of 0.2% Ropivacaine 15-20ml was given after a test dose of 1% lidocaine 5ml or 0.2% ropivacaine 5ml. Generally, the first dosage was at 25-30ml. The anesthesia effect, segments of block were measured and heart rates (HR),blood pressure (BP), blood oxygen saturation(SpO 2) were assessed before anesthesia, after anesthesia and at the end of surgery, meanwhile the breathing frequency, minute ventilation and maximal voluntary ventilation(MVV) were monitored. Blood gas, lactic acid and serum glucose were detected from 25 of the total case before and after anesthesia. Levels of sense obstacle and movement of bilateral upper limbs were recorded after operation. Results All 50 patients but one were finely anesthetized by elevation epidural block with 0.2% ropivacaine. Among them 39(78%) patients were blocked at C 5-T 8. No significant difference existed before and after anesthesia on breathing frequency, minute ventilation and maximal voluntary ventilation, and the values of blood gas in all those patients analysed were normal. Over 20% of decline on BP and obvious reduction on HR were found in 8 patients after anesthesia (P

Objective To explore the safety and the efficacy of the two-stage sedation administration method for the elderly in gastroscopic examination. Methods 128 elderly patients were divided into two groups according to age and body mass index (BMI), and were given sedation treatment before gastroscopic examination by two-stage administration method(group TSAM, n= 64)and continual administration method (group CAM, n= 64) of analgesics respectively. The following major data were recorded : ( 1 ) mean artery pressure (MAP) ;( 2 ) Blood oxygen saturation ( SpO2 ) ;(3)sedation level;(4) recovery time;(5) the amount of propofol used for sedation;(6) electrocardiogram (ECG) ;(7)the degree of pharyngeal malaise;(8) the oblivion degree of malaise. Results There was no significant difference in MAP alteration between two methods(P>0. 05). Compared with group CAM, the decreased degree of SpO2 was slighter and no patient's SpO2 was lower than 90% in group TSAM (P<0. 05). Fifty-seven patients in group TSAM fell into sedative state for gastroscopy with OAA/S score 2, while sixty patients in group CAM with OAA/S score 2, which represented a deeper sedation level in group CAM (P<0. 01). The recovery time was shorter and the amount of propofol used was significantly less in group TSAM than in group CAM (P<0. 01). During the process of gastroscopic exmaination, ST-T change and arrhythmia in ECG were not seen in either of these two groups. The pharyngeal malaise of patients in group TSAM was more severe than in group CAM (P<0. 01). However, there was no difference in the oblivion degree of malaise between two methods(P>0.05). Conclusions The two-stage sedative administration method is safer and more effective for gastroscopic examination for the elderly.

Objective To explore the factors related to vasovagal syncope (VVS) in children. Methods The clinical data of 125 children with conifrmed VVS were collected. According to the frequency of syncope during the ifve years from ifrst episode to the time of head-up tilt test, the children with 2 or 3 episodes of syncope were assigned into the low episode group, and the children with 4 or more episodes of syncope were assigned into the high episode group. The two groups were analyzed and compared. Results Among the 125 children, 84 children (67.2%) were in the low episode group and 41 children (32.8%) were in the high episode group. The single factor analysis showed that the age at head-up tilt test, onset of syncopal, causes of syncope, history of carsickness, and positive family history were associated with high attack frequency. The results of non-conditional logistic regression analysis showed that causes of syncope (OR?=?3.723, 95%CI:1.163-11.918, P?=?0.027), history of carsickness (OR?=?5.929, 95%CI:2.066-17.015, P?=?0.001), and positive family history (OR?=?6.794, 95%CI:2.006-23.013, P?=?0.002) were the independent risk factors of high attack frequency. Conclusions The causes of syncope (excluding persistent standing), history of carsickness, and positive family history have important clinical signiifcance in predicting high attack frequency of VVS in children.

Objective To validate the feasibility and accuracy of iterative decomposition of water and fat with asymmetry and least squares estimation-quantitative fat imaging (IDEAL-IQ) in fat quantification using fat-water model. Methods A homogeneous fat-water mixture model consisting of various known fat-fractions were described, and the fat fraction was 0.00, 0.01, 0.02, 0.04, 0.06, 0.08, 0.10, 0.14, 0.18, 0.22, 0.26, 0.30 g/ml respectively. A water-vaseline separated model was also described. IDEAL-IQ was performed. Thin slices were acquired for fat-water mixture model and repeated 3 days later. Nineteen slices of 14 mm-thick parallel to the water-vaseline boundary in 1 mm steps from vaseline to water
were acquired. The fat-fractions in 11 slices of fat-water mixture model were measured on FatFrac images. Accuracy was assessed through single sample t test or Kolmogorov-Sirmov test. Measured fat-fractions of the same known fat-fraction were assessed through independent samples t test between two scan times. Linear regression was used to assess the relationship between known fat-fractions and measured fat-fractions. Slices containing the water-vaseline boundary were measured with ROI in the middle of the FatFrac images. The relationship between measured fat-fractions and locations of scanning was exploded using curve fitting. Results (1) Fat-water mixture model: no significant difference(P>0.05) was found between measured fat-fractions and known fat-fractions when it was 0.00, 0.02, 0.06 and 0.08 g/ml with the measured fat-fractions 0.60%, (2.30 ± 0.60)%, (5.76 ± 1.40)%, (7.62 ± 1.40)% respectively for the first time. No significant difference(P>0.05) was found between measured fat-fractions and known fat-fractions when it was 0.00, 0.02, 0.10 g/ml with the measured fat-fractions 0.04%, (2.32 ± 0.60)%, (9.41 ± 1.00)%respectively for the second time. Measured fat-fraction was inlinear relation with known fat-fraction:Y=0.898X+0.224, r2=0.993, P<0.01, F=36 129.548.(2) Water-vaseline separated model: measured fat-fraction increased as scanning location changed, Y=0.045X2-0.499X-4.474, r2=0.978, P<0.05, F=350.623.Conclusions IDEAL-IQ can be used to quantify fat content with good repeatability and can accurately assess the actual fat content from the linearrelationship.

Along with the development of economy and society, type 2 diabetic mellitus (T2DM) has become one of the most common diseases at the global level. As one of the complications of T2DM, diabetic neuropathic pain (DNP) stubbornly and chronically affects the health and life of human beings. In the pain field, dorsal root ganglion (DRG) is generally considered as the first stage of the sensory pathway where the hyperexcitability of injured neurons is associated with different kinds of peripheral neuropathic pains. The abnormal electrophysiology is mainly due to the changed properties of voltage-gated sodium channels (VGSCs) and the increased sodium currents (I(Na)). Curcumin is an active ingredient extracted from turmeric and has been demonstrated to ameliorate T2DM and its various complications including DNP effectively. The present study demonstrates that the I(Na) of small-sized DRG neurons are significantly increased with the abnormal electrophysiological characteristics of VGSCs in type 2 diabetic neuropathic pain rats. And these abnormalities can be ameliorated efficaciously by a period of treatment with curcumin.
