Objective To investigate the effect of external abdominal aorta compression on circulation during anesthetic induction in elderly patients. Methods A prospective randomized controlled trial was conducted. Patients with age of 60-75 years old, requiring a general anesthesia for non-abdominal surgery, and with Ⅱ-Ⅲ class of American Society of Anesthesiologists (ASA) physical status classification, and admitted to General Hospital of Chinese People's Armed Police Forces from January to April in 2017 were enrolled. They were divided into abdominal aorta pressure group and control group according to random number method, with 20 patients in each group. In both groups, anesthesia was induced with midazolam, propofol, fentanyl and cisatracurium, and was maintained with propofol, remifentanil and cisatracurium. After successful intubation, the anesthesia machine was changed into mechanical ventilation. The patients in abdominal aorta pressure group were given abdominal aorta pressure 1 minute after induction of general anesthesia with midazolam till 5 minutes after intubation. The mean arterial pressure (MAP), heart rate (HR) and blood oxygen saturation (SpO2) were observed before anesthesia induction, immediately after anesthesia induction, immediately after intubation, 5 minutes and 10 minutes after intubation, respectively. The incidence of hypotension or bradycardia, and usage of ephedrine or atropine were recorded. Results There were no significant differences in MAP [mmHg (1 mmHg = 0.133 kPa): 83.6±4.7 vs. 82.9±4.7], HR (bpm: 67.3±5.9 vs. 65.9±5.7) and SpO2 (0.962±0.007 vs. 0.960±0.009) before anesthesia induction between abdominal aorta pressure group and control group (all P > 0.05). Immediately after anesthesia induction, the MAP and HR in control group were significantly decreased as compared with those before anesthesia induction [MAP (mmHg): 70.0±8.7 vs. 82.9±4.7, HR (bpm): 60.7±6.7 vs. 65.9±5.7, both P < 0.05], and they were also significantly lower than those of abdominal aorta pressure group [MAP (mmHg): 83.1±3.9, HR (bpm): 66.8±4.9, both P < 0.05]. Immediately after intubation, the MAP and HR in control group were significantly increased as compared with those immediately after anesthesia induction [MAP (mmHg): 78.9±7.9 vs. 70.0±8.7, HR (bpm): 67.3±2.7 vs. 60.7±6.7, both P < 0.05], but the changes in MAP and HR in abdominal aorta pressure group were not obvious. During the anesthesia induction period, there was no statistical difference in SpO2 change between the two groups. During induction of anesthesia, no adverse reaction was found in the abdominal aorta pressure group, but 4 patients with hypotension and 2 patients with bradycardia were found in the control group. Two patients with hypotension were treated with ephedrine, and 2 patients with bradycardia were treated with atropine. Conclusion Anesthesia induction of elderly patients with abdominal aorta pressure can help maintain hemodynamic stability.

Objective To investigate the expression of VEGF-C in breast cancer and its relationship with lymph node metastasis. Methods VEGF-C expression was assessed by immunohistochemistry in 78 cases of breast cancer. The relationship between expression of VEGF-C and lymph node status and clinicopathological features in breast cancer was analyzed. 20 cases of breast fibroadenoma was taken as control group. Results The expression of VEGF-C was significantly higher in breast cancer group than that in fibroadenoma group(P<0.01). VEGF-C was significantly higher in axillary lymph node-positive group than that in axillary lymph node-negative group(P<0.05). No relativity was found between VEGF-C and patient age, tumor size, estrogen receptor status, progesterone receptor status, and clinical stage. Conclusion The high expression of VEGF-C has a relativity with lymph node metastasis of breast cancer and may be important for the breast cancer's prognosis.

Objective To compare the effect of lymph node dissection by VATS lung cancer resection surgery and conventional lung cancer surgery.Metnods 120 patients with non-small cell lung cancer were selected and randomly divided into observation group (n =60) and control group (n =60) according to the digital table.The control group was given conventional resection of lung cancer treatment,the observation group was assisted thoracoscopic lung resection treatment.The postoperative drainage,postoperative ambulation time,postoperative hospital stay,the number of lymph node metastasis and incidence rate of postoperative complications were observed.Results The time of postoperative drainage,get out of bed and postoperative hospital stay of the observation group were all shorter than those of the control group [(2.43 ± 0.54) d vs.(5.82 ± 1.35) d,(1.23 ± 0.29) d vs.(3.87 ± 0.75) d,(2.59 ± 0.63) d vs.(6.92 ± 1.27) d;t =18.059,25.430,23.658,all P ＜ 0.05)].The lymph node dissection number of the two groups had no statistically significant difference(x2 =1.008,P ＞ 0.05).The positive rate of lymph node metastasis in the observation group was lower than that in the control group(x2 =7.033,P ＜ 0.05).The incidence rate of postoperative complication of the observation group was lower than that of the control group (x2 =6.708,P ＜ 0.05).Conclusion Video-assisted thoracoscopic lung resection for non-small cell lung cancer patients with lymph node dissection is better than conventional lung surgery,and it is worthy of studying.

Mechanical ventilation is regarded as an effective means of replacing artificial ventilation during cardiopulmonary resuscitation (CPR), and has been widely used in the treatment of cardiac arrest (CA) patients. However, there are still some controversial issues remaining to be settled, such as the assessmentof the effectiveness of mechanical ventilation, the selection of the optimal oxygen concentration (FiO2), tidal volume (VT), respiratory frequency, and mode of ventilation during the CPR process. The pros and cons of positive pressure ventilation are also inconclusive. We reviewed and summarized the related research in recent years, and recommended that the intermittent positive pressure ventilation (IPPV) of volume controlled with small VT (6-7 mL/kg), low ventilation rates (10 times/min), and pure oxygen could be applied during the mechanical ventilation of CPR. The best mechanical ventilation strategy still needs further experimental researches to discover and explore.

To promote the technical training and scientific popularization of cardiopulmonary resuscitation (CPR) in China, the Cardiopulmonary Resuscitation Specialized Committee of Chinese Research Hospital Association combined with the Science Popularization Branch of the Chinese Medical Association wrote "2018 National consensus on cardiopulmonary resuscitation training in China". The formation was based on the general outline about "2016 National consensus on cardiopulmonary resuscitation in China", and to implement the important strategies included the "three pre" policy, prevention, precognition, and pre-warning, before the cardiac arrest (CA); the "three modernization" methods, standardized, diversified and individualized, during the CA; and the "three life" strategies, the rebirth, the extra and the extended, after the CA; and also combined with the concrete National conditions and clinical practice of China area. The document summarized the evidence of published science about CPR training till now, and recommend the establishment of "the CPR Training Triangle" according to the Chinese National conditions. The bases of the triangle were system, training and person, the core of which was CPR science. The main contents were: (1) The "three training" policy for CPR training: the cultivation of a sound system, which included professional credibility, extensive mobilization and continuous driving force, and the participation of the whole people and continuous improvement; the cultivation of scientific guidelines, which included scientific content, methods and thinking; and the cultivation of a healthy culture, which included the enhancement of civic quality, education of rescue scientifically, and advocate of healthy life. (2) The "three training" program of CPR training: training professional skills, which included standard, multiple, and individual skills; training multidimensional, which included time, space, and human; and training flexible, including problem, time, and innovation oriented. (3) The "three party" direction of CPR training, the application for achievement translation, which included scientific translations, skill propagators, and cultural advocates; the precision disseminators, which included accurate communication sources, channels, and dissemination of the audience; and theoretical innovation guides, which included scientific, popular science and communication theory. That integrated the wisdom of scholars, melt the thought of genius, and created the act of envoy for Chinese and foreign CPR training. The training program should be suitable for different trainee, no matter who is trainer or trainee. The release of the expert consensus on the 2018 CPR training will make the National CPR education into the new training era with definite direction, clear target and fully standard of China.
