Objective To evaluate the potentiation of neuromuscular block produced by rocuronium during isoflurane anesthesia. Methods Sixty ASA Ⅰ -Ⅱ patients (39 male, 21 female), aged 18-56 yr, weighing 42-88 kg undergoing ENT, oral or facial plastic surgery were enrolled in this study. The patients were premedicated with atropine 0.01 mg?kg-1 . Anesthesia was induced with diazepam 0.1 mg?kg-1 , pethidine 1mg?kg-1 and droperidol 50?g?kg-1. Oro- or naso-tracheal intubation was accomplished under topical anesthesia. After intubation the patients received hydroxydione 2.5 g and fentanyl 5 ?g?kg-1 . The patients were mechanically ventilated. Anesthesia was maintained with inhalation of 50% N2O in O2 alone (groupⅠ) or combined with 0.6% isoflurane (group Ⅱ ) or 1.2% isoflurane (group Ⅲ ) . A bolus of rocuronium 0.6 mg?kg-1 was given during maintenance of anesthesia. Neuromuscular function was monitored using TOF response measured by accelerography (Biometer, Denmark). (1) Onset time (time from the end of injection to maximum depression of T1 ) , (2) the duration of T1 = 0, (3) time from the end of injection to recovery of T1 to 25% , 50% and 90% control, (4) recovery index (time from T, 25%-75%) were recorded. End-tidal isoflurane concentration was monitored.Results The onset time was significantly longer in group Ⅰ[ (1.7?0.2) min] than that in group Ⅱ[ (0.9?0.1) min] and groupⅢ[(0.8?0.1) min] ( P

Objective To explore relationships of expression of hypoxia?inducible factor?1α(HIF?1α), vascular endothelial growth factor(VEGF)and protein kinase B(P?Akt)with angiopoiesis and cell apoptosis. Methods Biopsy specimens were collected from skin lesions of 32 patients with lichen planus and normal skin of 20 patients with lipomyoma, and subjected to paraffin embedding. Immunohistochemical staining was performed to measure expression of HIF?1α, VEGF and P?Akt, and TUNEL technique was used to detect apoptosis of keratinocytes in these paraffin?embedded tissue sections. Microvessel density (MVD)was assessed by counting CD34?labeled vascular endothelial cells. Results HIF?1α, VEGF and P?Akt were moderately or strongly expressed in lichen planus lesions, but absent or weakly expressed in normal skin of controls, and the expression of HIF?1α, VEGF and P?Akt was significantly higher in the lichen planus group than in the control group (all P < 0.01). HIF?1α was mainly expressed in nuclei of keratinocytes, while VEGF and P?Akt were expressed in the cytoplasm of keratinocytes. In addition, the lichen planus group showed significantly increased MVD(21.27 ± 6.54 vs. 10.26 ± 1.10 microvessels/high?power(200 ×)field, t = 5.607, P < 0.01)and apoptosis rate of keratinocytes(72.81% ± 9.234% vs. 28.16% ± 3.464%, t = 8.431, P < 0.01) compared with the control group. Pearson correlation analysis showed that there were positive correlations between HIF?1αand VEGF expression, between VEGF and P?Akt expression, and between P?Akt and HIF?1αexpression in the lichen planus group(r=0.625, 0.453, 0.455, respectively, all P<0.01), and expression of HIF?1α, VEGF and P?Akt was all positively correlated with MVD(r=0.721, 0.646, 0.671, respectively, all P<0.01). Conclusion HIF?1αand its downstream target genes VEGF and P?Akt may play a certain role in the occurrence of lichen planus.

Objective:To explore the clinical application in urinary system stones of the inspection technologies intravenous pyelography (IVP),computer tomography urography (CTU) and magnetic resonance urography (MRU). Methods:We collected 100 cases of urinary system stones on which 80 were carried out to IVP,60 to CTU and 35 to MRU,25 patients were implemented all 3 examinations. CTU and MRU are reconstructed with multi-level reorganization (MPR),curved projection reproduction (CPR),volume reproduction (VR) and the maximum intensity projection (MIP). Results:Stones were found in 73 patients of the 80 people by IVP,the diagnosis rate is 91.3 %. Stones were found in all the 60 patients except 1 by CTU with images direct and accurate,the diagnosis rate was 98.1 %. By the MRU,stones were found in 20 of the 35 patients at a display rate of 57.1 %,with images displayed in a low stone location signal,filling defect and the hydrocele circs of renal pelvis and ureter. Conclusion:IVP is a simple method,easy-to-patient acceptance and has a high detection rate of stones; CTU has a good image quality and the detection rate is higher than the stone IVP. By combining with the original cross-sectional image,the rate of diagnosis is up to 98%; as a non-invasive and no contrast agent approach,MRU is also very important in the diagnosis of stones.

ObjectiveTo study the effect of adding various doses fentanyl to 0.75% bupivacaine for spinal anesthetic in the population undergoing inguinal hernia repair surgery. MethodsThe population of 100 patients belonging to ASA class Ⅰ and Ⅱ ,scheduled for elective inguinal hernia repair, were randomized to receive a spinal anesthetic with 2 ml 0.75% bupivacaine and 1.0 ml saline (group B),or 50 μg/ml fentanyl 0.1,0.2,0.4,0.6 ml(group BF5, group BF10, group BF20,group BF30),each group with 20 cases.Subarachnoid block was established in the left lateral position in L2-3 space by use of a midline approach. The volume of injected drug was kept constant at 3 ml. The time to the highest level of sensory block, the time for regression until T12 level, the time for complete motor recovery, the maintenance duration of the analgesia,the anesthesia effect of the groups, duration of surgery, drug-related side effects were assessed and recorded.ResultsThe time of the highest level of sensory block in group BF30 was shorter than that in group B,group BF5, group BF 1 0, group BF20 (P < 0.05 ), but group B and group BF5 was longer than group BF10,group BF20, group BF30(P < 0.05 ). The time of regression to T12 level in group BF20 was longer than that in group B, group BF5, group BF10, group BF30 (P<0.05),but group B and group BF5 was shorter than group BF10, group BF20, group BF30(P< 0.05 ). The time for complete motor recovery and the maintenance duration of the analgesia in group B and group BF5 was shorter than that in group BFI0,group BF20, group BF30 (P < 0.05 ). The occurrence of pruritus in group B (0) was lower than that in group B F5 (8 cases),group BF10 (3 cases), group BF20 (6 cases), group BF30 (6 cases)(P<0.05). There were no cases of respiratory depression in five groups. ConclusionsIt suggests that in the population receiving spinal anesthetic for hernia repair surgery, addition of 10 μ g fentanyl to 0.75% bupivacaine significantly improves the quality and duration of analgesia. No further advantage occurs if the dose of fentanyl is increased among 30 μg.

Background:The incidence of duodenal Brunner’s gland hyperplasia is low and the etiology and pathogenesis has not yet been clarified. Aims:To investigate the relationship between duodenal Brunner’s gland hyperplasia and Helicobacter pylori( Hp ) infection. Methods:A total of 96 patients with duodenal Brunner ’s gland hyperplasia diagnosed by pathological examination from October 2005 to December 2013 at People’s Hospital of Xinjiang Uygur Autonomous Region were enrolled in this study,and 270 cases without duodenal Brunner’s gland hyperplasia were served as controls. Hp infection was detected by 14 C-urea breath test( 14 C-UBT). The relationship between duodenal Brunner’s gland hyperplasia and Hp infection was analyzed. Results:In the duodenal Brunner ’s gland hyperplasia group,75 patients were Hp positive,the proportion of Hp infection was 3. 57( 75/21 ). In the control group,110 cases were Hp positive,the proportion of Hp infection was 1. 45(160/110). The difference between the two groups was statistically significant(χ2 =10. 97,P=0. 001). Hp infection was a risk factor of the genesis of duodenal Brunner’s gland hyperplasia( OR=2. 46, 95% CI:1. 44-4. 19). Conclusions:Hp infection may be related with the genesis of duodenal Brunner’s gland hyperplasia.
