Objective To compare the treatment effects,dosimetry,and toxicities to organs at risk of intensity-modulated radiation therapy (IMRT) and 3-dimentional conformal radiotherapy (3DCRT) plans for cervical carcinoma patients with recurrence and metastasis. Methods 62 cervical carcinoma patients with recurrence and metastasis were analyzed retrospectively, and divided into two groups including intensitymodulated radiation therapy group (n=29) and 3-dimentional conformal radiotherapy group (n=32).Patients were performed with 6 MV-X ray.The regimen was 1.8-2.2 Gy/f,1 f/d,18-33 times in total.Prescribed dose was 40-60 Gy and median dose was 52.8 Gy. At the same time for the IMRT group 29 cases were performed with 3DCRT, which was designed using the same prescribed dose to compare radiation dose distributed in organs at risk (OAR).Results The maximum dose of the two plans showed that bladder and small intestine in IMRT plans were lower than that in 3DCRT (P<0.05), showing the IMRT's protective advantage. The maximum dose of PTV in IMRT plans were significantly higher than 3DCRT (P<0.05). In the group of IMRT plans, the overall 1-,2-,and 3-year survival rates were 65.5 %(19/29), 42.1%(8/19), and 25.0 %(2/8),respectively,the median survival time was 19 months,of 28 deaths,21 patients died of tumor progression,7 patients died of distant metastases.In the group of 3DCRT plans,the overall 1-,2-,and 3-year survival rates were 60.6 %(20/33),35.0 %(7/20),and 14.3 %(1/7),respectively,the median survival time was 17 months,of 32 deaths, 24 patients died of tumor progression, 8 patients died of distant metastasis. There were no significant differences in overall 1-, 2-, and 3-year survival rates between the two groups (P>0.05). The incidence rate of toxicity in the IMRT plans was significantly lower than that in the 3DCRT plans, especially for patients with Ⅰ level and Ⅱ level.Conclusion The treatment effects of the IMRT plans are better than the 3DCRT plans for cervical carcinoma patients with recurrence and metastasis. IMRT plans can improve radiation dose in tumors and reduce the dose distributed in normal issue and reduce the incidence of the side effect.

Objective:To evaluate the efficacy of remimazolam-propofol-sufentanil for anesthesia in patients undergoing painless gastroscopy.Methods:Eighty American Society of Anesthesiologists physical statusⅠor Ⅱ patients, aged 20-59 yr, weighing 44-69 kg, scheduled for elective painless gastroscopy, were divided into 2 groups ( n=40 each) using a random number table method: remimazolam-propofol-sufentanil group (group RPS) and propofol-sufentanil group (group PS). The patients in group RPS received successive intravenous injection of sufentanil 0.1 μg/kg, remimazolam 0.15 mg/kg and propofol (at a rate of 4 mg/s). The patients in group PS received intravenous injection of sufentanil 0.1 μg/kg and propofol (at a rate of 4 mg/s). When Observer′ s Assessment of Alertness/Sedation Scale score was 0, gastroscopy was performed.The consumption of propofol, time of anesthesia, time for gastroscopy, emergence time and discharge time were recorded.The number of intraoperative assisted respiration cases, body movement and occurrence of adverse reactions at the time of discharge were observed. Results:Compared with group PS, the consumption of propofol was significantly decreased, and the time of anesthesia, emergence time and discharge time were shortened in group RPS ( P<0.05). There was no significant difference in the time for gastroscopy, the number of intraoperative assisted respiration cases, body movement and the occurrence of adverse reactions at discharge time between the 2 groups ( P>0.05). Conclusion:Remimazolam-propofol-sufentanil produces better efficacy for anesthesia than propofol-sufentanil in patients undergoing painless gastroscopy.

Objective To investigate the risk factors resulting in the perioperative liver failure and death for the HBV-associated hepatocellular carcinoma (HCC) patients with or without cirrhosis.Methods The method of retrospective case-control study was performed.The clinicopathological data of 1 083 HCC patients with positive HBsAg who received curative liver resection at the Southwest Hospital from January 2008 to December 2012 were collected.According to the absence or presence of cirrhosis,the HCC patients with positive HBsAg were divided into the 2 groups,including the cirrhosis group (633 patients) and the non-cirrhosis group (450patients).The intraoperative conditions (operation time,volume of intraoperative blood loss,rate of blood transfusion,rate of pringle maneuver) and postoperative conditions (incidence of perioperative complications,duration of postoperative hospital stay,perioperative mortality) of HCC patients were observed.The gender,age,alanine transaminase (ALT),aspartate transaminase (AST),albumin (Alb),total bilirubin (TBil),platelet (PLT),Child-Pugh classification,operation time,volume of intraoperative blood loss,blood transfusion,pringle maneuver,extent of liver resection,number of tumors,tumor diameter,tumor thrombus and liver cirrhosis were enrolled and prognostic factors resulting in perioperative liver failure and death for the HCC patients were explored.Measurement data with skewed distribution were presented as M (range) and comparison between the 2 groups was analyzed using Mann-Whitney U test.Count data were presented as counts (percentage) and comparison between the 2 groups was analyzed using chi-square test or Fisher exact probability.Univariate analysis was performed by chi-square test and multivariate analysis was performed by Logistic regression model (forward).Results (1) The intraoperative conditions:the volume of intraoperative blood loss were 500 mL (range,30-7 000 mL) in the cirrhosis group and 400 mL (range,50-8 000 mL) in the non-cirrhosis group,with a statistically significant difference between the 2 groups (Z =-2.209,P < 0.05).The operation time,rate of blood transfusion and rate of pringle maneuver were 250 minutes (range,82-715 minutes),29.86% (189/633),62.24% (394/633) in the cirrhosis group and 242 minutes (range,85-738 minutes),27.11% (122/450),66.67% (300/450) in the non-cirrhosis group,respectively,with no statistical differences between the 2 groups (Z =-1.212,x2 =0.969,2.236,P >0.05).(2) The postoperative conditions:the incidence of perioperative complications was 30.49%(193/633) in the cirrhosis group and 21.11% (95/450) in the non-cirrhosis group,with a statistically significant difference between the 2 groups (x2 =11.851,P < 0.05).The incidence of lung infection,abdominal infection and liver failure were 6.48% (41/633),2.69% (17/633),5.53% (35/633) in the cirrhosis group and 3.56% (16/450),0.89% (4/450),1.33% (6/450) in the non-cirrhosis group,respectively,with statistically significant differences between the 2 groups (x2 =4.502,4.465,12.713,P < 0.05).The duration of postoperative hospital stay was 15 days (range,0-70 days) in the cirrhosis group and 14 days (range,0-71 days) in the non-cirrhosis group,with a statistically significant difference between the 2 groups (Z =-3.448,P < 0.05).The perioperative mortality was 5.85% (37/633) in the cirrhosis group and 2.44% (11/450) in the non-cirrhosis group,with a statistically significant difference between the 2 groups (x2=7.181,P < 0.05).(3)Results of risk factors affecting perioperative liver failure:①results of univariate analysis showed that age,AST,Alb,Child-Pugh classification,operation time,volume of intraoperative blood loss,blood transfusion,extent of liver resection,tumor diameter,liver cirrhosis with positive HBsAg were associated with perioperative liver failure in HCC patients (x2=5.013,7.979,8.855,16.968,14.148,9.764,18.511,11.749,5.534,12.713,P<0.05);age,AST,Alb,Child-Pugh classification,operation time,blood transfusion,extent of liver resection and tumor diameter were

intraoperative blood loss > 1 200 mL was an independent risk factor affecting perioperative liver failure in the non-cirrhosis group (OR =15.077,95%CI:2.695-84.353,P < 0.05).(4) Risk factors affecting perioperative death:①results of univariate analysis showed that gender,Alb,TBil,Child-Pugh classification,blood transfusion,extent of liver resection,tumor diameter,tumor thrombus and liver cirrhosis were associated with perioperative death in HCC patients with positive H BsAg (x2=4.462,8.783,4.212,4.869,7.189,11.745,6.837,4.323,7.181,P <0.05);Alb,extent of liver resection and tumor diameter were associated with perioperative death in the cirrhosis group (x2=12.173,12.793,10.981,P < 0.05);blood transfusion and tumor thrombus were associated with perioperative death in the non-cirrhosis group (x2 =5.836,6.417,P < 0.05).② Results of multivariate analysis showed that Alb <38 g/L,extent of liver resection ≥ 3 segments and liver cirrhosis were independent risk factors affecting perioperative death in HCC patients with positive HBsAg (OR =2.560,2.657,2.567,95% CI:1.382-4.742,1.471-4.800,1.283-5.134,P < 0.05);Alb < 38 g/L,extent of liver resection ≥ 3 segments and tumor diameter≥5 cm were independent risk factors affecting perioperative death in the cirrhosis group (OR =3.003,2.533,3.060,95% CI:1.495-6.034,1.251-5.128,1.135-8.251,P<0.05);blood transfusion and tumor thrombus were independent risk factors affecting perioperative death in the non-cirrhosis group (OR =3.755,4.036,95% CI:1.047-13.467,1.126-14.469,P < 0.05).Conclusions Liver cirrhosis is an independent risk factor for perioperative liver failure and death in HCC patients with positive HBsAg.The risk of perioperative liver failure and death in HCC patients with cirrhosis is significantly higher than that in HCC patients without cirrhosis,and there is a difference in the risk factors for perioperative liver failure and death.

In order to study the regularity of shedding virus from infected SPF chickens and the formation of aerosol of H9N2 subtype AIV, SPF chickens were bred in a positive and negative pressure isolator. Aerosol samples were collected by AGI-30 (All Glass Impinger-30) extractor, and simultaneously trachea and cloaca samples were collected by tracheal swabs and cloacal swabs in different periods after challenged with vi- ruses. The above-mentioned samples were detected by HI, Dot-ELISA and RT-PCR methods. The results in- dicated that aerosols were isolated from the 4 days to the 43 days after inoculation. It was proved that H9N2 subtype AIV could copy themselves in respiratory passage and cloaca, and then could formation of aerosols. AIV H9N2 subtype could be isolated from cloacal and tracheal swabs 3 days after inoculation and lasted for 45 days, viruses were detected from all infected SPF chickens on 7 days.
