Objective To analyse tratment strategies and to evaluate the relation between different therapies and survival rate of patients of with asynchronous liver metastases after pancreatic cancer surgery (PCLM).Methods From January 2006 to January 2012,48 patients with PCLM were included in this study,and their medical records were retrospectively analyzed.Results Among the 48 patients,27 cases of liver metastases were found within six months after surgery,and the survival rate for 1,3 and 5 years was 22.2％,3.7％ and 0％,respectively,with the median survival of 6 months,and 21 cases of liver metastases were found after six months,and the survival rate for 1,3 and 5 years was 85.7％,30.6％ and 9.2％,with the median survival of 15 months,and the difference between the two groups was statistically significant (P ＜ 0.01).After pancreatic cancer surgery and adjuvant gemcitabine chemotherapy,the probability of liver metastases was 33.3％ (8/24) within six months,the median disease-free survival time was 8 months and the disease-free survival rate for 1,3 and 5 years was 20.8％,4.3％ and 0％.For patients without adjuvant gemcitabine chemotherapy,the probability of liver metastases was 79.2％ (19/24),the median disease-free survival time was 3 months and the disease-free survival rate for 1,3 and 5 years was 4.2％,0％ and 0％,and the difference between the two groups was statistically significant (P ＜ 0.01).The overall survival for patients undergoing resection of liver metastases combined with gemcitabine treatment was better than the other groups (P ＜ 0.01).And the overall survival for patients undergoing transhepatic arterial embolization (TACE) combined with gemcitabine treatment was better than TACE group,gemcitabine group or the observation group (P ＜0.05).There were no difference in overall survival between TACE group,gemcitabine group and observation group.Conclusions Pancreatic cancer patients who develop liver metastasis within six months after surgery have poor prognosis,but postoperative chemotherapy can delay the development of liver metastasis.For patients with resectable lesion,resection of asynchronous liver metastasis is the treatment of choice,and TACE combined with gemcitabine has better efficacy than that of single treatment.

OBJECTIVETo analyze the risk factors of liver metastasis in patients after radical resection of pancreatic cancer.

METHODSOne hundred and twenty-four patients with non-metastatic, resectable pancreatic cancer treated in our department between 2006 and 2012 were included in this study. All of these patients underwent resection of the primary tumor combined with extensive lymph node dissection. The development of postoperative liver metastases was carefully followed up, and the clinicopathological factors and molecular characteristics were evaluated by univariate analysis and multivariate logistic regression using SPSS 16.0 software.

RESULTSForty-eight cases of liver metastases were found among the 124 cases of pancreatic cancer after radical surgery (38.7%). The rate of liver metastasis of pancreatic cancer after radical surgery in the age groups < 40, 40-60, and > 60 were 68.8%, 33.3% and 35.1%, respectively. The rate of liver metastasis in the body mass index (BMI) group < 20 kg/m2, 20-25 kg/m2, and > 25 kg/m2 were 21.6%, 44.1% and 52.6%, and the rate of liver metastasis in the time between the onset and diagnosis groups ≥ 3 months and < 3 months were 59.4% and 31.5%, respectively. The rate of liver metastasis in patients with preoperative fatty liver was 14.3% and it was 43.7% in patients without preoperative fatty liver. The rate of liver metastasis in patients of histological high, medium and low grade was 10.0%, 35.4% and 49.0%, respectively. The rate of liver metastasis in patients with venous tumor thrombus was 68.8% and it was 34.3% in patients without venous tumor embolus. The rate of liver metastasis in patients with postoperative chemotherapy was 31.2% and it was 51.1% in patients without postoperative chemotherapy. All those differences had statistical significance (P < 0.05). Univariate analysis revealed that age, body mass index (BMI), time between the onset and diagnosis, preoperative fatty liver, histological grading, tumor invasion depth, venous tumor embolus, and postoperative chemotherapy were significantly related to postoperative liver metastasis. Multivariate analysis revealed five statistically independent risk factors for postoperative liver metastasis: BMI, time between onset and diagnosis, preoperative fatty liver, histological grading, and venous tumor embolus.

CONCLUSIONSOur data suggest that patient's BMI, time between onset and diagnosis, histological grade, and venous tumor embolus are significantly correlated with postoperative liver metastases in patients with pancreatic cancer. Pancreatic cancer patients with preoperative fatty liver have less postoperative liver metastasis.

Objective:To investigate the therapeutic effect of different prone position ventilation (PPV) on patients with severe acute respiratory distress syndrome (ARDS) at high altitude.Methods:The severe ARDS patients who met the Berlin standard admitted to the department of intensive care unit (ICU) of Qinghai Provincial People's Hospital from January 2017 to January 2020 were enrolled. The patients with classic PPV treatment (i.e. alternate prone supine position, about 16 hours per day) were included in the discontinuous PPV group; the patients with modified PPV treatment (i.e. alternate left and right prone positions 20°-30°, every 4 hours and continuous treatment for 24 hours per day) were included in the continuous PPV group. The oxygenation index (PaO 2/FiO 2), mechanics of breathing, ventilator parameters before treatment and 72 hours after treatment, and mechanical ventilation time, the length of ICU stay, and related complications between the two groups were analyzed. Results:Eighteen cases were treated with continuous PPV and 20 cases were treated with discontinuous PPV. There were no significant differences in gender, age, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), PaO 2/FiO 2, lung compliance, driving pressure (ΔP) and positive end expiratory pressure (PEEP) before treatment between the two groups. Compared with before treatment, PaO 2/FiO 2 in discontinuous PPV group and continuous PPV group was increased significantly after 72-hour treatment [mmHg (1 mmHg = 0.133 kPa): 99.7±15.4 vs. 55.5±6.3, 121.8±25.3 vs. 55.1±7.1, both P < 0.05], lung compliance was improved significantly (mL/cmH 2O: 36.8±2.4 vs. 28.0±2.0, 43.4±6.7 vs. 27.7±2.1, both P < 0.05), and ΔP was decreased significantly [cmH 2O (1 cmH 2O = 0.098 kPa): 10.5 (10.0, 12.0) vs. 13.0 (12.3, 14.0), 10.0 (8.0, 12.0) vs. 13.0 (12.0, 14.0), both P < 0.05], PEEP was also decreased [cmH 2O: 12 (12, 14) vs. 14 (13, 14), 10 (8, 10) vs. 14 (12, 15), both P < 0.05], and the indexes in continuous PPV group were improved more significantly than those in discontinuous PPV group [PaO 2/FiO 2 (mmHg): 121.8±25.3 vs. 99.7±15.4, lung compliance (mL/cmH 2O): 43.4±6.7 vs. 36.8±2.4, ΔP (cmH 2O): 10.0 (8.0, 12.0) vs. 10.5 (10.0, 12.0), PEEP (cmH 2O): 10 (8, 10) vs. 12 (12, 14), all P < 0.05]. The duration of mechanical ventilation and the length of ICU stay in the continuous PPV group were significantly shorter than those in the intermittent PPV group [days: 6.0 (5.0, 7.3) vs. 8.0 (7.0, 9.0), 9.7±1.5 vs. 12.1±2.2, both P < 0.01]. During the PPV treatment, there were 3 cases of cheek skin damage and 2 cases of ear skin damage in the continuous PPV group, and 3 cases of facial skin damage in the intermittent PPV group. There was no significant difference in the incidence of complications between the two groups ( χ2 = 0.321, P = 0.571). All patients were repaired normally after PPV, without adverse consequences. Conclusion:Continuous PPV is more effective than discontinuous PPV in the treatment of severe ARDS patients at high altitude, and the related complications are did not increased in prolonged time of PPV.

Objective: To explore the effective application of ventilation at prone position on patients with severe acute respiratory distress syndrome(ARDS) at high altitude. Methods: A total of 19 severe ARDS patients in ICU of Qinghai Province People's Hospital were enrolled from February in 2016 to February. in 2018, all of them ventilated at the prone position, several indicators were assessed:heart rate (HR), respiratory (R), mean arterial pressure (MAP); blood gas indicators: arterial oxygen partial pressure (PaO₂), inhaled oxygen concentration (FiO₂), carbon dioxide partial pressure (PaCO₂), blood oxygen saturation (SpO₂), oxygenation index (PaO₂/FiO₂), PH, lung compliance, PEEP and so on, which assessed before and 12h, 24h, 48h, 72h after the ventilation. Results: FiO₂ and PEEP significantly declined at 12 h, 24 h, 48 h, 72 h after ventilation at the prone position. HR, MAP, R, PaO₂, PaCO₂, SPO₂, PaO₂/FiO₂, pH and lung compliance significantly improved (F=32.30,24.73, P < 0.05). Conclusions It was an effective method for ARDS patients to improve the oxygenation status and vital signs at the plateau with ventilation used at the prone position and probably nursing intervention, which have clinical application value.

Objective:To investigate the current practice environment of male nurses in Qinghai province, and understand the professional environment and turnover intention of male nurses, provide ideas and theoretical basis for continuous improvement of the working environment of male nurses in hospitals.Methods:From September to October 2020, the practice environment and turnover intention of male nurses in Qinghai Province were investigated by using the method of convenience sampling and using the general data questionnaire, the Nurse Practice Environment Assessment Scale and the turnover intention table.Results:A total of 155 registered male nurses in Qinghai Province participated in this survey, and the overall evaluation score of the practicing environment of nurses in Qinghai Province was (74.38±22.63) points, among which the highest score was that nurses could write nursing records in time (85.24±20.99) points, and the lowest score was that nurses had the opportunity to participate in the internal management of the hospital (55.03±30.55) points. The total score of resignation intention was (14.34±4.35) points.Conclusion:The overall evaluation of the practicing environment of male nurses in Qinghai Province is fair, and their turnover intention is high. Nursing managers should attach importance to the cultivation of male nurses' feelings towards hospitals and professions, so as to reduce their turnover intention and stabilize the nursing team of male nurses.

Objective:To explore the effect of epalrestat combined with calcium dobesilate on cardiovascular and cerebrovascular diseases and oxidative stress in diabetes patients with peripheral neuropathy.Methods:In a retrospective analysis, 92 patients with diabetic peripheral neuropathy were admitted to the Department of Endocrinology and Metabolism Hospital of Bozhou People’s Hospital from Jun. 2018 to Jun. 2021, which were divided into observation group and control group according to the different treatment methods, with 46 cases in each group. The control group were treated with epalrestat. On this basis, the observation group were given calcium dobesilate combined treatment. The two groups were compared in terms of the Michigan diabetes neuropathy score (MDNS) Michigan neuropathy screening instrument (MNSI) score, oxidative stress reaction [serum superoxide dismutase (SOD), reduced glutathione (GSH) ], clinical efficacy, complications and adverse reactions Using t-test and chi square test.Result:After treatment, the MDNS and MNSI scores of both groups decreased, and the observation group [ (23.49±3.73), (8.49±1.97) ] were lower than the control group [ (28.49±3.85), (11.53±2.28) ] ( t=8.337, 6.843, P<0.05) ; After treatment, the levels of SOD and GSH in both groups increased compared to those before treatment, and the observation group [ (38.96±4.89), (89.79±6.92) ] were higher than the control group those [ (36.42±4.61), (86.74±6.20) ] ( t=2.563, 2.226, P=0.012, 0.028) ; The clinical efficacy of the observation group was higher than that of the control group ( Z=1.592, P=0.042) ; The incidence of complications in the observation group after 1 year was significantly lower than that in the control group ( χ2=4.389, P=0.036) ; The incidence of adverse reactions in the observation group was slightly lower than that in the control group ( χ2=0.155, P=0.694) . Conclusion:Epalrestat combined with calcium dobesilate is effective in the treatment of diabetes peripheral neuropathy, can effectively reduce complications, and has high treatment safety, which is worthy of clinical application.

Objective To investigate the surgical methods and the differences of postoperative complications in esophageal canccr patients aged 60 years and over undergoing different operation models.Methods A total of 542 elderly esophageal cancer patients who underwent thoracic surgery at our hospital between January 2010 and December 2016 were enrolled.Patients were divided into 4 groups:left thoracic incision operation group (n =202),lvor-Lewis two incisions operation group (right chest posterolateral and upper abdomen median) (n=251),three incision operation group (left neckright chest-abdominal midian (n =29),and McKneown under-endoscope minimally invasive operation group (n=60).Clinical data,including the postoperative days,numbers of lymph nodes dissection,pulmonary infection,serous membrane fluid,arrhythmia,chylous fistula,gastric emptying dysfunction and anastomotic leakage,were retrospectively compared between the four groups.Results There was no significant difference in the postoperative days,serous membrane fluid,arrhythmia,chylous fistula,gastric emptying dysfunction and anastomotic leakage (P ＞ 0.05).The number of lymph nodes dissection in Sweet group,Ivor-Lewis group,Mckeown operation group and minimally invasive Mckneown group were (12.9±7.4)、(19.3±8.6)、(14.3±6.9)and(15.4±7.3)respectively.The number of lymph nodes dissection was more in the Ivor-Lewis group than in the other three groups (F =23.915,P =0.000).Sweet group,Ivor-Lewis group,Mckeown group and minimally invasive Mckneown group were 31.7％、40.2％、24.1％ and 50.0％ respectively.The incidence of pulmonary infection was higher in the minimally invasive surgery group than in the other three groups (x2 =9.941,P =0.019).Conclusions Ivor-Lewis surgery is more effective in lymph nodes dissection and has a lower incidence of complications in elderly esophageal cancer patients.The minimally invasive surgery group has a higher incidence of pulmonary infection than in the other surgical groups,which may be related with the immaturity of endoscopic technique.
