Objective To study the efficacy of surgical treatment in hilar cholangiocarcinoma patients. Methods One hundred and four cases underwent surgical treatment of hilar cholangiocarcinoma were retrospective enrolled in the study from 1998 to 2008, including 45 cases of radical resection, 38 cases of palliative resection, vitro bridge drainage in 21 cases, 93 cases of postoperative patients. Ninty-three patients were followed up for 5 - 67 months, the different procedures of the treatment was summerized. Results Oneyear survival rate of radical resection and palliative resection was 80. 0% ( 32/40 ) and 86. 8% ( 33/38 ),respectively. No significant difference between the two groups (P ＞0. 01 ) were found; 2-year survival rate was 67. 5% (27/40) and 39. 5% ( 15/38), with significant difference between the two groups (P ＜0. 01 ) ;3-year survival rates were 37.5% ( 15/40 ) and 13.2% ( 5/38 ), with significant difference between the two groups (P＜0. 05). Palliative resection had higher 1-year survival rate than in vitro bridge drainage(P ＜ 0.01).Conclusion Surgical treatment of hilar cholangiocarcinoma is the most effective way to prolong the survival time of radical resection, radical surgery had better efficacy than palliative surgery, and palliative surgery is superior to external drainage. In patients of severe jaundice combined with biliary drainage infection, preoperative bridge drainage would improve the safety.

Objective To systematically review,evaluate and summarise the best evidences about lifestyle guidance for women at high risk of GDM in domestic and international databases,therefore to provide evidences for nurses to guide the women at high risk of GDM to prevent GDM.Methods Systematic search BMJ Best Practice,Cochrane Library,PubMed,Web of Science,Science Direct,Medlive,National Institute for Health and Care Excellence,International Diabetes Federation,International Diabetes and Pregnancy Study Groups,Australian clinical practice guidelines(ACPG),ACPG,CNKI,Wanfang,CBM datebase from June 2015 and June 2022,which provide the lifestyle guidance for women at high risk of GDM.Two of the researchers examined and evaluated the quality of the included articles respectively.Results A total of 22 articles were included,including 6 of clinical guidelines,2 of expert consensuses,10 of systematic reviews or Meta analysis and 4 of randomized controlled trials(RCTs).A total of 17 pieces of evidence were extracted and summarised into 4 themes,including early screening,diet guidance,exercise guidance and weight guidance.Conclusion The best evidence summary in this study provide an evidence-based clinical nursing for health care workers to guide the lifestyle and formulate lifestyle intervention programs for high-risk groups of GDM.

Objective:To understand the function of diaphragm and analyze the clinical factors affecting the function of diaphragm by measuring twitch tracheal pressure (TwPtr) in patients with mechanical ventilation and in the weaning phase.Methods:Patients with more than 48 hours of invasive mechanical ventilation admitted to the department of critical care medicine of the First Affiliated Hospital of Guangzhou Medical University from December 2015 to March 2017 were enrolled. After the patient entered the weaning stage, TwPtr of patients was monitored by two-way non repetitive automatic respiratory trigger device, the effects of duration of mechanical ventilation, severe pulmonary infection, sedative application and chronic obstructive pulmonary disease (COPD) on weaning were analyzed.Results:A total of 62 patients were included, of which 45 were male and 17 were female. The average age was (66.8±11.7) years old. Twenty-three cases had severe pneumonia. The absolute value of TwPtr in severe pneumonia group was lower than that in non-severe pneumonia group [cmH 2O (1 cmH 2O = 0.098 kPa): 10.40±5.81 vs. 14.35±5.22, P = 0.021]. However, there was no significant difference in the duration of mechanical ventilation between the severe pneumonia group and non-severe pneumonia group [days: 26 (17, 43) vs. 15 (11, 36), P = 0.091]. In 62 patients with mechanical ventilation, there was a negative correlation between TwPtr and duration of mechanical ventilation ( r = 0.414, P = 0.002), there was also a negative correlation between the duration of mechanical ventilation and TwPtr after the assessment of diaphragm function ( r = 0.277, P = 0.039). There was a linear relationship between TwPtr and sedatives ( r = 0.220, P = 0.040), but there was no correlation between TwPtr and COPD ( r = -0.178, P = 0.166). Conclusions:For patients in the weaning stage of mechanical ventilation, severe pulmonary infection is one of the factors that affect the diaphragm dysfunction. There is a certain correlation between the diaphragm dysfunction and the use of sedatives.
