Objective To investigate the effect of rocuronium on spectral entropy during induction of general anesthesia in patients of Uygur nstionality. Methods Forty ASA Ⅰ or Ⅱ patients (Uygur nationality) of both sexes, aged 20-50 yr, weighing 45-70 kg, undergoing elective surgery under general anesthesia, were divided into 2 groups ( n = 20 each): normal saline (NS) group and rocuronium group (group R). Anesthesia was induced with target-controlled infusion of propofol. The initial target plasma concentration wan net at 2 μg/ml. The concentration wan then increased by 0.5 μg/ml every 4 min until response entropy (RE) was decreased to 45 and maintained for 4 min. When the plasma concentration was equal to the effect-site concentration, iv rocuronium 0.6 mg/kg was injected in group R, while group NS received the equal volume of NS instead. Fentanyl 3 μg/kg was injected intravenously at 3 min after recuronium administration. The patients were tracheal intubated and mechanically ventilated. State entropy (SE) and RE were recorded immediately before induction (baseline, To), before rocuronium administration (T1), 2 main after rocuronium administration (T2) and at 0, 1, 2 and 3 min after intubation (T3-6). The difference between RE and SE wan calculated. Results The RE value at T3 and T4 and the difference between RE and SE at T2.5 were significantly lower in group R than in group NS ( P ＜ 0.05). Conclusion Rocuronium can decrease the RE value and degree of increase in the difference between RE and SE during induction of general anesthesia in patients of Uygur nationality, which may affect the accuracy of spectral entropy in monitoring the depth of anesthesia.

Objective:To investigate the correlation between microRNA-497 (miR-497) expression and invasion and metastasis and prognosis of colorectal cancer (CRC).Methods:The expression of miR-497 in 93 CRC patients (CRC group), 30 colorectal adenoma polyps (colorectal adenomatous polyp group) and 30 healthy patients (normal control group)were detected by real-time fluorescence quantitative polymerase chain reaction (qRT-PCR); meanwhile, the content of serum carcinoembryonic antigen (CEA) was detected by chemiluminescence; After 3 years follow-up, the expression of miR-497 was measured again; the correlation between the expression of miR-497 and the clinicopathological characteristics and prognosis of CRC was analyzed.Results:The expression of miR-497 in CRC group was significantly lower than that at the end of postoperative treatment, adenomatous polyps group and normal control group ( P<0.01), and the content of CEA in CRC group was significantly higher than that at the end of postoperative treatment, adenomatous polyps group and normal control group ( P<0.01); At the end of postoperative treatment, the expression of serum miR-497 in CRC group was lower than that in normal control group ( P<0.05), and the content of serum CEA was higher than that in normal control group ( P<0.05). The diagnosis positive rate of serum miR497 expression in CRC group was significantly higher than that of serum CEA ( P<0.01), and they showed no correlation ( r=0.232, P>0.05). The pre-and post-operative serum miR-497 expression levels in the recurred and metastasis group were significantly lower than those in the no postoperative recurrence and metastasis group ( P<0.01). The preoperative expression of miR-497 was related to the differentiation degree of CRC, tumor node metastasis (TNM) stage, lymph node metastasis, distant metastasis and survival period ( P<0.01), but not with the age, sex, tumor size and location of the patients ( P>0.05). Cox multivariate analysis showed that tumor differentiation, TNM stage, preoperative miR-497 expression, lymph node metastasis and distant metastasis were all independent risk factors influencing prognosis of CRC patients ( P<0.05); The survival rate of 1, 2, 3 years in the miR-497 low expression group was lower than that in the miR-497 high expression group ( P<0.05). Conclusions:The preoperative low serum miR-497 expression levels are closely relative with invasion and metastasis and poor prognosis of CRC, and can be a prognostic indicator of CRC. The reduced postoperative serum miR-497 expression levels may be a predictor of the postoperative recurrence and metastasis of CRC.

Objective To investigate the relationship between quantitative detection of T lymphoma invasion and metastasis inducing factor (Tiaml) mRNA and invasion,metastasis and prognosis of patients with colorectal cancer.Methods The quantitative expression of Tiam1 mRNA in cancer tissues in colorectal cancers (n =97),in tissues of colorectal adenomatous polyposis (n =49) and normal control (n =30) were detected with real-time fluorescence quantitative-polymerase chain reaction (PCR).The relationship between the quantitative expression of Tiam1 mRNA in colorectal cancer tissues and the invasion,metastasis and the prognosis were analyzed.Results The levels of Tiam1 mRNA expression in the colorectal cancer group,were significantly higher than those in colorectal adenomatous polyposis group and normal controlgroup [(14.45±4.87)2-△△△Ct vs (3.77 ±3.15)2-△△Ct,(1.06 ±0.65)2-△△Ct,P ＜0.01].The levels of Tiam1 mRNA expression in the adenomatous polyposis with high grade intraepithelial neoplasia were signifiCantly higher than those in the adenomatous polyposis with low grade intraepithelial neoplasia [(5.26 ±2.45)2-△△Ct vs (3.78 ±2.19)2-△△Ct,P ＜0.01],which were both significantly higher than those in the adenomatous polyposis with no intraepithelial neoplasia [(2.13 ± 1.64)2-△△Ct,P ＜0.05 or P ＜ 0.01].The levels of Tiam1 mRNA expression in colorectal cancer group were positively related to the differentiated degree of tumor,depth of invasion,lymph node metastasis,tumor node metastasis (TNM) stages and the postoperative recurrence (P ＜ 0.01),and were negatively related to the postoperative survival time (P ＜0.01).Multivariate Cox regression analysis revealed that levels of Tiam1 mRNA expression in cancer tissues were independent prognostic factor for colorectal cancer (Exp =4.043).Conclusions The high Tiam1 mRNA expression levels in cancer tissues are closely related to invasion,metastasis and poor prognosis of colorectal cancer,and may be a prognostic indicator of colorectal cancer.The increase expression of Tiam1 mRNA in colorectal adenomatous polyposis may be related to colorectal tumorigenesis.

ObjectiveTo investigate the effect of anisodamine on the expression of connexin 43 (Cx43) in swine ventricular myocardium after resuscitation from cardiac arrest.Methods The experiment was conducted on healthy pigs, and they were randomly divided into three groups, namely sham group, epinephrine group (control group) and anisodamine group (experimental group, animals were resuscitated combined with injection of 0.4 mg/kg of anisodamine), with 5 pigs in each group. Model of ventricular fibrillation was reproduced by alternating current challenge, and cardiopulmonary resuscitation (CPR) was performed 8 minutes after cardiac arrest. Left ventricular myocardium was harvested at 24 hours after restoration of spontaneous circulation. The expression and distribution of Cx43 were observed by immunofluorescence, Cx43 mRNA expression was assessed with reverse transcription-polymerase chain reaction (RT-PCR), and the protein expressions of Cx43 and phosphorylation of Cx43 (p-Cx43) were analyzed by Western Blot.Results The positive expression of Cx43 in ventricular muscle was distributed uniformly, mostly at the end-to-end linkage of myocardial cells, with a few side-to-side linkage in sham group. The positive expression of Cx43 in control group was significantly weaker than that in the sham group, and the signal intensity was significantly declined (4.35±2.10 vs. 10.02±3.66,P< 0.01). The positive expression of Cx43 at the end-to-end linkage and side-to-side linkage was irregular in experimental group, and the signal intensity was obviously higher than that in the control group (7.91±2.54 vs. 4.35±2.10,P< 0.05), but it was significantly weaker than that in the sham group (7.91±2.54 vs. 10.02±3.66,P< 0.05). For control group and experimental group, the Cx43 mRNA and protein expressions were significantly lower than those of the sham group [Cx43 mRNA (A value): 0.32±0.05, 0.32±0.03 vs. 0.48±0.07; Cx43 protein (A value): 0.43±0.03, 0.50±0.07 vs. 0.65±0.04, allP< 0.01], and there were no significant differences between experimental group and control group (allP> 0.05). The p-Cx43 protein expression of control group was significantly lower than that of the sham group (A value: 0.22±0.03 vs. 0.37±0.06,P< 0.01), and it was significantly higher in the experiment group than that in the control group (A value: 0.29±0.07 vs. 0.22±0.03, P< 0.01), but there was no significant difference with the sham group (P> 0.05). No significant difference in p-Cx43/Cx43 was found among sham, control, and experiment groups (0.57±0.09, 0.51±0.05, 0.58±0.06, all P> 0.05).ConclusionAnisodamine can improve the abnormal expression of Cx43 in ventricular muscle of pigs with cardiac arrest, which may be related to the protection effect of anisodamine on cardiac conduction.

Background and purpose:Reasonable proportion with blood less than half of the surgical system, cancer patients during surgery prone to acute massive blood loss, this study aimed to investigate blood transfusion in the patients who diagnosed with cancer during operation in the Afifliated Tumor Hospital of Xinjiang Medical University, and in order to improve the intraoperative blood transfusion and make it more scientiifc and more reasonable.Methods:The patients who were taken selective operations and heterogenous blood transfusions in the Afifliated Tumor Hospital of Xinjiang Medical University from Oct. 2012 to Dec. 2013 were enrolled, and the clinical data were retrospectively surveyed and investigated.The intraoperative use of blood components and reasonableness in each department were analyzed.Results:The medical records of 299 blood transfusion receipts proportions of reasonable transfusion of RBC from department of gastrointestinal surgery, gynecology, orthopedics, hepatobiliary surgery, neurosurgery, urological surgery and thoracic surgery were 88.9%, 91.8%, 94.3%, 96.3%, 91.6%, 100%, 81.3%,respectively. And the proportions of reasonable transfusion of plasma were 86.2%, 71.8%, 96.4%, 78.4%, 100%, 100%, 87.5%, respectively. The proportions of low-volume blood transfusion and the combined transfusion of RBC and plasma were 62.5% and 43.2% in unreasonable blood transfusion.Conclusion:Except for the unreasonableness in very few departments, the intraoperative blood component transfusion is carried on fairly well. The medical staff still should be further trained in the appropriate use of blood and strengthened the knowledge on blood transfusion.

Objective To investigate the relationship between juxtapapillary duodenal diverticular (JPDD) and choledocholithiasis,and the effects of JPDD on endoscopic sphinctemtomy(EST) in treatment of choledocholithiasis.Methods Fifty-one cases of choledocholithiasis combined with JPDD (choledocholithiasis combined with JPDD group) and 210 cases of choledocholithiasis without JPDD (choledocholithiasis without JPDD group) were treated by EST,and the clinical data of patients in the two groups were retrospectively analyzed.The relationship between JPDD and choledocholithiasis was studied.The JPDD' influence on the intubation success rate of endoscopic retrograde cholangiopancreatography (ERCP),the success rate of the stone removal by EST and complication were analyzed.Results The incidences of choledocholithiasis in patients of JPDD diameter ＜ 1 cm,1-3 cm and ＞ 3 cm were 39.3％(11/28),53.2％ (33/62) and 7/8 respectively.The larger the JPDD diameter,the higher the incidence of choledocholithiasis,and there was statistical difference (P ＜ 0.01).The incidence of choledocholithiasis in peripheral type JPDD was significantly higher than that in parallel type and circumvolution type [81.0％(17/21) vs.41.9％(26/62) and 8/15],and there were statistical differences (P ＜0.05).There was no statistical difference in the intubation success rate of ERCP between the two groups (P ＞ 0.05),but the success rate of the stone removal by EST in choledocholithiasis combined with JPDD group was significantly lower than that in choledocholithiasis without JPDD group [91.8％ (45/49) vs.99.5％ (208/209)].The incidence of EST incision bleeding was significantly higher than that in choledocholithiasis without JPDD group [11.1％ (5/45) vs.1.9％ (4/208)],and there was statistical difference (P ＜ 0.01) ; there were statistical differences in the incidences of others complication between the two groups (P ＞ 0.05).Logistic regression analysis showed that JPDD was independent risk factor for EST incision bleeding (P =0.043).Conclusions JPDD is relative with choledocholithiasis.JPDD makes EST a little more difficult and risky,while EST is still a safe and effective therapy for choledocholithiasis patients combined with JPDD.

Objective To investigate the correlation between serum soluble epithelial cadherin (sE-cad) and postoperative recurrence and prognosis in patients with advanced gastric cancer.Methods The level of serum sE-cad in 85 patients with advanced gastric cancer (advanced gastric cancer group) was detected by ELISA technique preoperative and postoperative 1 month,and compared with 30 healthy controls(control group).The patients in advanced gastric cancer group were followed up for 3 years,the level of serum sE-cad in recurrent patients and non-recurrent patients was compared.Results The level of serum sE-cad in advanced gastric cancer group preoperative was significantly higher than that in control group [(24.3 ± 14.8) μ g/L vs.(9.4 ± 3.8) μ g/L,P ＜ 0.01].The level of serum sE-cad in advanced gastric cancer group was significantly decreased postoperative 1 month [(12.5 ± 6.4) μ g/L vs.(24.3 ± 14.8) μ g/L,P ＜0.01].The level of serum sE-cad in recurrent patients was significantly higher than that in non-recurrent patients and postoperative 1 month [(20.7 ±9.8)μg/L vs.(12.5 ±6.4),(14.8 ±6.2) μg/L,P＜0.01].Univariate analysis revealed that preoperative high serum sE-cad level was related with tumor size,differentiated degree,lymph node metastasis ratio,depth of tumor invasion (P ＜0.05),but had no relationship with histological type(P＞ 0.05).Elevated preoperative serum sE-cad level negatively affected the postoperative survival rate and recurrence rate.Multivariate Logistic regression anaiysis revealed that preoperative serum sE-cad level was an independent risk factor for postoperative 3 years survival rate in advanced gastric cancer (HR =2.068,P =0.013).Conclusions Preoperative elevated serum sE-cad level is related with pathologic features in patients with advanced gastric cancer,and may be an important prognostic factor.Postoperative monitoring the level of serum sE-cad is useful for evaluating the prognosis and recurrence.
