BACKGROUNDMediastinoscopy has experienced a renaissance due to the introduction of neoadjuvant treatment protocols and recognition of the limitations of noninvasive mediastinal staging of lung cancer by CT and PET. The aim of this study is to determine the value of video-mediastinoscopy in mediastinal staging of lung cancer.

METHODSA total of 60 patients who underwent video-mediastinoscopy for known or suspected lung cancer were retrospectively reviewed. There were 52 cervical mediastinoscopies, 2 parasternal mediastinoscopies and 6 combined procedures. All the patients were found to have enlarged mediastinal lymph nodes on radiographic examination of the chest (more than 1.0cm on its shortest axis).

RESULTSOf the 60 patients, 42 patients were found with N2 or N3 disease on video-mediastinoscopy and then were confirmed pathologically. The other 18 mediastinoscopy-negative patients underwent thoracotomy for pulmonary resection and mediastinal lymph node dissection in the same operative session, in which thoracotomy-proven N0 was found in 17 patients, and N2 in 1 patient (false-negative result by video-mediastinoscopy). The sensitivity, specificity, and accuracy of video-mediastinoscopy for mediastinal staging of lung cancer were 97.7%, 100% and 98.3%, respectively. In the entire group of 60 patients, there was 1 complication (1.7%) , and no perioperative death.

CONCLUSIONSVideo-mediastinoscopy is a highly effective and safe procedure. It can be used routinely in mediastinal staging of lung cancer.

Objective:To investigate the effects of dexmedetomidine on short-term prognosis in elderly patients with gastric cancer after laparoscopic radical gastrectomy.Methods:A total of 60 elderly patients with gastric cancer admitted to Shanxi Provincial Cancer Hospital from June 2018 to September 2019 were selected as the research objects. The patients were randomly divided into the observation group and the control group according to random number method, 30 cases in each group. All patients underwent laparoscopic radical gastrectomy. The patients in the control group received routine intravenous anesthesia, and the patients in the observation group were assisted with intravenous infusion of dexmedetomidine on the basis of anesthesia in the control group. The general situation during and after surgery, hemodynamics and postoperative delirium of patients in the two groups were observed and compared.Results:The anal exhaust time and hospitalization time in the observation group was shorter than that in the control group [(72±10) h vs. (79±13) h, t = 8.384, P = 0.031; (11.0±1.7) d vs. (12.9±1.9) d, t = 7.404, P = 0.022]. While the time of abdominal drainage was (8.4±2.8) d and (8.6±1.6) d, respectively in the observation group and the control group, and the difference was not statistically significant ( t = 0.958, P = 1.092); the volume of abdominal drainage was (534±50) ml and (545± 55) ml, respectively, and the difference was not statistically significant ( t = 0.847, P = 1.202). Compared with the preoperative baseline, the mean arterial pressure (MAP) in the two groups was stable during the operation. At extubation, the MAP in the control group [(104±5) mmHg, 1 mmHg = 0.133 kPa] was higher than that in the observation group [(92±7) mmHg] ( t = 7.383, P < 0.01); in the control group, the MAP at extubation was also higher compared with the preoperative MAP [(92±9) mmHg] ( P < 0.05). The heart rate in the observation group was lower than that before surgery and the same period in the control group.The incidence rate of delirium and suspicious delirium was 3% (1/30) and 7% (2/30) in the observation group, 10% (3/30) and 13% (4/30) in the control group within 7 d after surgery, and there were statistically significant differences in delirium and suspicious delirium between the two groups ( χ2 = 9.394, 7.485, all P < 0.05). Conclusion:Dexmedetomidine can reduce the incidence of delirium in elderly patients with gastric cancer after laparoscopic radical gastrectomy, and make the hemodynamics more stable and recovery faster.

0.05).Conclusions There is imbalance of Th1/Th2 cells in CHB children.Th1 cytokines are positively correlated with hepatic inflammatory activity.In the course of disease,Th2 cytokines are predominant and they have a correlation to the chronic prognosis of the illness.So we can conclude the degree and prognosis of disease by observing the change of Th1/Th2 cytokines in CHB children.

Objective To explore the effect of glutamine(Gln) on expression of nuclear factor kappa B(NF-?B) and heat shock protein 70(HSP70) in brain of young rats induced by lipopolysaccharide(LPS).Methods Ten days old Wistar rats were randomly divided into 3 groups by injection intraperitoneally different agonts,LPS group,normal saline control group(NS group) and Gln group(Gln 1.346 g/kg,1 hour before LPS).NF-?B and HSP70 distribution and expression in brain were deteted by immunohistochemistry.The levels of HSP70 in rats brain induced by LPS were detected by Western blot.SPSS 12.0 software was used.Results The nuclei of neuron in cerebral cortex in LPS group obviously cleared at 6 hours.The positive stain of nuclei in Gln group at 2 hours could not be seen.The stain of nuclei in cerebral cortex was weakened in LPS group at 6 hours by immunohistochemistry.HSP70 protein expression decreased with the measurement of Western blot,especially at 24 hours.HSP70 expression in LPS group was similar as that in NS group.The stain of nuclei in neuron in Gln group at 2 hours increased.It also showed the amount of protein expression increased in Western blot in group Gln at 2,6,12,24 hours(Pa

Objective To evaluate if the enteral nutrition have effect on the immune function and in- flammatory reaction after operating about gastric carcinoma.Methods 58 postoperative patients suffering from stomach cancer and colon cancer were randomly divided into the EN group and the TPN group.On the first postoperative day,nutrition fibre were given via nasal intestinal tube,increasing the capacity and drop- ping speed day by day until patients can eat liquid diet.While patients in the TPN group didn't eat anything until enterokinesia completely recovered.Observing on preoperative day 1 and on postoperative day 3 and day 8 respectively to check IgA,IgG,IgM,C3,C4,CRP,LYM,LYM%,TP,ALB,PA.Results The results showed that on the postoperative day 8,the target ascension extent was higher than that in the PN group.The statistical significance was very obvious(P

Totally 126 patients with malignant breast tumors diagnosed with ultrasound were followed up.The ultrasonic image characters were analyzed and compared with the pathologic outcomes. Ultrasound had a 92.1%(116/126) veracity in the diagnosis of malignant breast tumor,which were characterized by strong echo in the border of the tumors and halo (72.2%, 91/126).There were differences in ultrasonic images of malignant breast tumors with different pathologic types. Ultrasound can determine the character of most breast tumors.
