BACKGROUND: Subsequent to liver transplantation, pulmonary infection and new drug resistant strain frequently appear due to complex pathophysiological changes and abuse of antibiotics.OBJECTIVE: To collect the clinical data of 6 cases who underwent liver transplantation, and analyze the prevention and treatment measures of pulmonary infection after liver transplantation.DESIGN, TIME AND SETTING: Retrospective case analysis, performed in the Department of Hepatobiliary Surgery,First People's Hospital of Guangzhou between January and December 2004.PARTICIPANTS: Six cases that underwent liver transplantation and received treatment in the First People's Hospital of Guangzhou were recruited in the present study. All 6 cases underwent selective homologous whole liver transplantation, 5cases underwent modified orthotopic piggyback liver transplantation, and only 1 underwent classical orthotopic liver transplantation.METHODS: The clinical data of the 6 cases were retrospectively analyzed. After transplantation, basic disinfection,isolation, infection-protection measures should be taken. In addition, etiological information was collected. Chest X-ray was underwent to know the lung at the early stage. Aseptic manipulating was strictly performed during sputum aspiration.Gastrointestinal decompression and non-obstructed drainage were maintained to prevent aspiration. Moreover, preventive anti-infective treatment against the bacteria, fungi, and viruses was performed.MAIN OUTCOME MEASURES: Pulmonary infection and curative effects subsequent to liver transplantation.RESULTS: Of the 6 cases, 5 presented with pulmonary infection, including 1 at 4-11 days after transplantation and 1 at 1day after transplantation. One case died of respiratory failure. The remaining 5 cases were cured after standardized anti-infection, respiratory therapy, sputum aspiration, and nutritional support.CONCLUSION: Application of effective antibiotics, aseptic operation in sputum aspiration, and unobstructed respiratory tract drainage are important measures for treating pulmonary infection subsequent to liver transplantation.

Objective To evaluate the prognostic value of blood lactate (Lac) level in sepsis patients with or without diabetes.Methods 106 patients admitted to intensive care unit (ICU) of Zhongshan Hospital Affiliated to Fudan University from April 2015 to November 2016 were enrolled. The patients with age > 18 years and the length of hospital stay > 24 hours were included. Records including blood Lac, serum creatinine (SCr), white blood cell count (WBC), platelet count (PLT), sequential organ failure assessment (SOFA) on the first day of admission; minimum oxygen index (PaO2/FiO2) in 3 days after admission; mechanical ventilation, whether there was a history of diabetes, usage of biguanides, etiology control treatment, usage of continuous renal replacement therapy (CRRT) were collected. According to the level of blood Lac patients were divided into high Lac group (Lac > 2 mmol/L) and low Lac group (Lac ≤ 2 mmol/L);based on their diabetic history, sepsis patients were divided into the diabetes group and non-diabetes group. The survival curve of each group was analyzed by Kaplan-Meier regression analysis, and the factors influencing the prognosis were analyzed by multivariate Cox regression analysis.Results There were 76 males and 30 females sepsis patients, with an average age of (68.1±14.7) years old. In the 51 patients of low Lac group, there were 7 patients who suffered from diabetes. While in the 55 patients of high Lac group, there were 12 patients who suffered from diabetes. Compared with low Lac group, high Lac group had a higher age, higher SOFA score, and a lower proportion of patients who had the treatment of etiology control (allP < 0.05). There was no significant difference of blood Lac in sepsis patients with diabetes and those without diabetes (mmol/L: 3.03±2.73 vs. 2.81±2.40,P > 0.05). Kaplan-Meier survival curve analysis showed that the 90-day survival rate in the high Lac group was significantly lower than that in the low Lac group (56.36% vs. 90.20%,χ2 = 0.697,P = 0.008). The high Lac group without diabetes had lower survival rate, and the 90-day survival rate was significantly lower than that of the low Lac group without diabetes (58.14% vs. 90.90%,χ2 = 7.152,P = 0.007); there was no significant difference in 90-day survival rate between the high Lac group and the low Lac group with diabetes (50.00% vs. 85.71%,χ2 = 0.012,P = 0.914). Multivariate Cox regression analysis showed that blood Lac was an independent risk factor for the prognosis of sepsis patients [odds ratio (OR) = 3.863, 95% confidence interval (95%CI) = 1.237-12.060,P = 0.020]. After stratification according to their diabetic history, the blood Lac was an independent risk factor for the prognosis of sepsis patients without diabetes (OR = 4.816, 95%CI = 1.407-15.824, P = 0.010), but the blood Lac had no effect on the prognosis of sepsis patients with diabetes (OR = 0.000, 95%CI =0.000-1.103,P = 0.270).Conclusions The predictive value of blood Lac on sepsis patients with or without diabetes was different. The blood Lac was related with the prognosis of sepsis patients without diabetes, while further study should be conducted for the prognostic value of blood Lac in sepsis patients with diabetes, and it's possible to increase the cut-off-point of Lac level in these patients.

Objective To define the assessment dimensions of community-based elderly care service.Methods Firstly 11 assessment dimensions of elderly care service needs were teased out through literature review and group discussion, these were illness, self-care ability, vision, risk of falls, willingness/information self-expression ability, the comprehension in others' willingness/information, depression, anxiety, family care ability, self-desires for old-age support, family-desires for old-age support.Then 37 experts were invited to reconfirm and empower theose assessment dimensions with two rounds of Delphi method.Results Results showed that the enthusiasm and authority degree of experts were favorable in two rounds, and the results from the second round showed strong opinion coordination.Finally, 12 assessment dimensions were confirmed, in which financial situation of the aged added and used for reference.After weight calculation, illness was weighted the highest (0.11), while vision and the degree of anxiety were weighted lowest in 11 dimensions (0.07).Conclusion The reliability of the assessment dimensions of the aged service needs is high.This study had positive significance on the solution of the dilemma in elderly care at the present stage.

Objective To systematically evaluate the role of laparoscopic living donor hepatectomy in living donor liver transplantation (LDLT).Methods A systematic literature search was conducted on Medline-Pubmed,Embase,Cochrane Library to find studies on laparoscopic living donor hepatectomy for LDLT.All extracted data were analyzed using the RevMan 5 software.Results Ten studies with a total of 1 059 participants were included in this analysis.Laparoscopic donor hepatecomy (LDH) was associated with significantly less intraoperative blood loss [SMD =-0.39,95％ CI (-0.73,-0.05),P ＜ 0.05],lower peak level of postoperative total bilirubin [SMD =-0.24,95％ CI (-0.47,-0.01),P ＜ 0.05]and longer operative time [SMD =0.50,95％ CI (0.04,0.96),P ＜0.05] when compared with those operated with open surgery.On subgroup analyses,hospitalization stay decreased in patients who underwent LDLT with grafts obtained by complete living donor hepatectomy (LDH) and left lateral sectionectomy (both P ＜ 0.05).LDH was comparable to open surgery in donor complication rates and in-hospital cost (P ＞ 0.05).There were no differences on the harvested liver graft size,ischemic time,recipient postoperative liver function and complications between the two groups (P ＞ 0.05).Conclusions Laparoscopic hepatectomy in living donor is a safe procedure for graft-harvesting,which improved the clinical outcomes of the donor,liver graft and recipient in LDLT.It has also the advantages of reduced blood loss,low peak levels of postoperative total bilirubin and short hospitalization stay.

Objective: To evaluate the surgView-RFT electromagnetic navigation system in radiofrequency thermocoagulation(RFT). Methods: 6 foramen ovales of 3 cadavers were punctured by 3 beginners. Every one tried 5 times by free-hand and 5 times by SurgView-RFT electromagnetic navigation-guidance. After each puncture, CT scans were used as golden standard to measure the distance between the tip of needle and the anterior margin of the foramen ovale. T test and variance of SAS 6.12 statistical software was used to do the statistic analysis. Results: The punctures by free-hand failed, and the distances between the tip of needle and the anterior margin of the foramen ovale were 8-10.6 mm. The punctures by navigation guidance were successful, and the distances between the tip of needle and the anterior margin of the foramen ovale were 2.68-3.54 mm. The error of navigation system was 0.59 mm which was verified by CT scan. There was significant difference between free-hand puncture and navigation-guided puncture. Conclusion: The surgView-RFT electromagnetic navigation system is characteristic with high performance, high accuracy and minimal invasion, while it is applied in training or clinical using.

OBJECTIVETo discover and identify differentially expressed genes associated with colorectal adenoma formation and the role of RegIV in colorectal adenoma differentiation.

METHODSA subtracted cDNA library was constructed with cDNAs that were isolated from either the normal mucosa or adenoma tissue of a single patient. Suppressive subtractive hybridization (SSH) combined with virtual northern blotting was used to characterize differentially expressed genes and contigs were assembled by electronic cloning (in silico cloning) with the EST database. Semi-quantitative RT-PCR was performed in 9 colorectal adenomas.

RESULTSThe amino acid sequence was determined with open reading frame (ORF) prediction software and was found to be 100% homologous to the protein product of RegIV (a novel gene isolated from a large inflammatory bowel disease library). RegIV was found to be highly expressed in all of the adenoma samples (9/9) compared with the normal mucosa samples, while 5/6 cases showed RegIV to be more strongly expressed in adenocarcinoma.

CONCLUSIONRegIV may play an important role in the initiation of colorectal adenoma differentiation, and its detection may be useful in the early diagnosis of colorectal adenoma formation.

Objective To investigate the clinical treatment and outcomes of severe community-acquired pneumonia (CAP) complicated with mediastinal emphysema after renal transplantation. Methods Clinical data of9 patients with severe CAP complicated with mediastinal emphysema after renal transplantation were retrospectively analyzed. The acute physiology and chronic health evaluationⅡ(APACHEⅡ) and oxygenation index were recorded when the patients were admitted to the intensive care unit (ICU). The complications of mediastinal emphysema and corresponding treatment were observed. The treatment course during the ICU, mortality rate in ICU, ICU stay time and hospital stay time were recorded. All patients underwent pathogenic examinations. Results The APACHEⅡ score of9 patients with severe CAP complicated with mediastinal emphysema after renal transplantation was 14 (8-21) scores and the oxygenation index was 150 (133-189) mmHg. Among 9 patients, 3 cases were infected by bacteria alone, 3 cases were infected by bacterial infection combined with viral infection, 1 case was infected by mycobacterium tuberculosis complicated with other bacterial infection and 1 case was viral infection. No pathogenic evidence was detected in the remaining 1 patient. Mediastinal emphysema complicated with subcutaneous emphysema occurred in 7 cases and pneumothorax occurred in 6 cases. Treatment methods included anti-infection, modified immunosuppressive program, mediastinal drainage, thoracic closed drainage, subcutaneous incision and extracorporeal membrane oxygenation (ECMO) treatment. Six patients received invasive mechanical ventilation (IMV), 2 received non-invasive positive pressure ventilation (NIV) and 1 received high-flow nasal oxygen cannula (HFNC). Among 9 patients, the mortality rate in ICU was 6/9, the remaining 3 patients were recovered and discharged, the ICU stay time was 26 (17-40) d, and the total hospital stay time was 27-61 d. Conclusions Mediastinal emphysema is a serious complication of patients presenting with severe CAP after renal transplantation with a high mortality rate. For these patients, imaging evaluation, timely drainage and full sedation should be strengthened, and ECMO treatment should be delivered when necessary.

Objective To investigate the value of the apparent diffusion coefficient (ADC)measurement in assessment of tumor grade and myometrial invasion of endometrial carcinoma (EC).Methods 80 EC patients and 28 cervical cancer patients with normal endometrium were studied retrospectively.1.5T conventional MRI and DWI (b=0,1 000 s/mm2)were performed,and ADC values were calculated by two radiologists.Statistical analyses were performed by using SPSS 19.0 and Medcalc software.Results The mean ADC values (×10-3mm2/s)were 0.851±0.131,0.752±0.099,0.681±0.089 for G1,G2 and G3 EC,respectively.Significant statistical differences were achieved for the three groups (G1 vs G2:P=0.005;G2 vs G3:P=0.03;G1 vs G3:P< 0.000 1).For the prediction of G3,the area under the curve (AUC)of 0.851 and the cut-off value of ≤0.742×10-3mm2/s were identified,with the sensitivity, specificity and accuracy of 88.24%,76.19% and 85%,respectively.Conclusion There are significant statistical differences between histologic grades of EC.ADC measurement may have the potential to select G3 EC patients.
