Objective To investigate the factors influencing the outcomes of patients with ALI/ARDS.Method Data of 63 patients with ALI/ARDS in ICU,Cancer Hospital,Chinese Academy of Medical Science,from January 2005 to December 2006,were retrospectively analyzed.Patients were divided into survivor group(n=39)and non-survivor group(n=24)according to different outcomes,and equally,patients were classified in the rcspect of different causes as pulmonary origin and extra-pulmonary origin.Results The incidence of ALI/ARDS was 5.2%(63/1201)in ICU.The univariate analysis showed that the differences in the length of mechanical ventilation(P=0.028),blood creatinine level(P=0.031),oxygenation index(P=0.023),between survivor group and non-survivor group.In addition,the differences in acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)scores and sequential organ failure assessment(SOFA)on the admission day were significant between survival group and non-survival group(P<0.001,respectively).Logistic regression analysis showed that APACHE Ⅱ scores was the only independent predictor of the mortality in patients with ALI/ARDS(P=0.015,OR:3.809,95%CI:1.295～11.203).There was no significant difference in one-year survival between pul-monary origin cause of ALI/ARDS group and exwa-pulmonary origin cause of ALI/ARDS group(63.9% vs.55.4%).There was significant difference in one-year survival between ARDS and ALI group(44.9% vs.88.9%,P<0.05).Conclusions APACHE Ⅱscores on the admission day of patients is the only independent predictor of the mortality in patients with ALI/ARDS,whereas the underlying cause of ALI/ARDS does not matter to the survival of patients.

OBJECTIVE To investigate the distribution of fungus infection and risk factor of postoperation patients with tumors. METHODS We analyzed 1 256 postoperation patients in our hospital ICU from Aug 2000 to Aug 2004,and found that there were 88 fungus infection patients(7%),the pathogens were tested and analyzed. RESULTS The fungus infection,which dominated in respiratory tract and digestive tact,had an increasing tendency,the most prevalent fungus of infection was Candida albicans. CONCLUSIONS The risk factors of fungus infection are mechanical ventilation,the useness of antibiotics,radiotherapychemotherapy,and invasive treatment,it is very important to diagnose early and treat in time.

Objective To evaluate the incidence and to investigate risk factors of supraventricular arrhythmia (SVAs) in postoperative cancer patients in intensive care unit ( ICU ). Methods Data of 570 patients consecutively admitted to oncologic surgical ICU of Cancer Hospital of Chinese Academy of Medical Sciences from Nov. 2008 to Oct. 2009 were retrospectively collected. Univariate and multivariate logistic analysis were conducted for potential factors that influenced SAVs. Results Thirteen patients with a history of atrial fibrillation (AF) were excluded and 557 patients were eligible for the study. SVAs occurred in 72 patients ( 12. 93% ). Multivariate analysis showed four independent predictors of SVAs including age ( OR = 1. 066,95%CI: 1. 034 - 1. 099,P ＜0. 001 ) ,a history of coronary heart diseases ( OR = 2. 644,95% CI: 1. 459 - 4. 790,P ＜ 0. 05), sepsis ( OR = 2. 374,95% CI: 1. 098 - 5. 135, P ＜ 0. 05 ) and intra-thoracic procedure ( OR =2. 322,95 % CI: 1.061 - 5.084, P ＜ 0. 05 ) . ICU length of stay, severity ( APACHE Ⅱ scores in SVAs patients) were significantly greater in patients who were not affected by SVAs ( ICU stay: [2 ( 1 ～ 77 )]vs [3 ( 1 ～ 40 )]days,P ＜ 0. 001; APACHE Ⅱ score: [9 (0 ～ 37 )] vs [11 (3 ～ 38 )], P = 0. 001 ). Nine cases died in SVAs patients ( 12. 5% ) and 19 died in the non-SVAs patients (3.9%), with significant difference between the two groups( x2 = 9. 673, P = 0. 002). Conclusion In oncologic surgical ICU, the incidence of SVAs is high. Age,history of coronary heart diseases, sepsis and intra-thoracic procedure were independent rsik factors of SVAs. SVAs prolong ICU length of stay. SVAs is a marker of critical illness severity.

A microfluidic chip with integrated microelectrode for real-time dopamine detection was designed and fabricated. The chip consisted of a polydimethylsiloxane ( PDMS) channel plate and a glass electrode plate. One central channel as the culture chamber of neural stem cells and two lateral channels for transport of the culture medium were integrated on the PDMS channel plate. Microelectrodes for real-time dopamine detection were integrated on the glass electrode plate. To solve the problem in demoulding the PDMS channel plate from the silicon mould, a novel demoulding method was developed. An Au-Au-Au three-electrode system was constructed, and it performed well in electrochemical detection. The performance of the microfluidic chip was primarily studied by detecting dopamine dissolved in the medium for the culture of neural stem cells. The limit of detection was 3. 92 μmol/L, the linear detection range was from 10 μmol/L to 500 μmol/L, and the detection reproducibility from different chips was less than 4%.

This study was aimed to develop the method for determination of mannitol and meglumine in diterpene lactones of Ginkgo Injection. The HPLC-ELSD was used to determine mannitol and meglumine in diterpene lactones of Ginkgo Injection. The analysis was carried out on Waters XBridge Amide (4.6 mm í 150 mm, 3.5 μm) column. The mobile phase was the mixture of acetonitrile, and 50 mmol·mL-1 ammonium acetate with a linear gradient elu-tion at a flow rate of 1.0 mL·min-1. The column temperature wad maintained at 30℃. The operating conditions of the ELSD were a nebulizer nitrogen with the flow rate of 2.0 L·min-1 and an evaporator tube at the temperature of 90℃. The results showed that mannitol had a good linear relationship in a range of 1.9665 μg - 19.665 μg. The average recovery rate was 100.57% (RSD = 0.92%, n = 9). The meglumine showed a good linear relationship in a range of 0.4838 μg - 4.638 μg. The average recovery rate was 100.67% (RSD = 0.72%, n = 9). It was concluded that this method was simple and accurate with good reproducibility. It met with the requirement of the determination of the contents of mannitol and meglumine in diterpene lactones of Ginkgo Injection.

Objective:To study the treatment outcomes of combining percutaneous transhepatic one-step biliary fistulation (PTOBF) followed by two stages cholangioscopic treatment for type Ⅰ and Ⅱa hepatolithiasis which developed after Roux-en-Y cholangiojejunostomy, and in treatment of cholangiojejunostomy stenosis.Methods:The clinical data of 95 patients with type Ⅰ and Ⅱa hepatolithiasis which developed after Roux-en-Y cholangiojejunostomy and were treated at Shandong Second Provincial General Hospital from September 2016 to December 2020 were analyzed retrospectively. There were 36 males and 59 females, with the age of (51.2±15.3) years (range 14 to 75 years). These patients initially underwent PTOBF rigid choledochoscopy, followed by electronic choledochoscopy via the fistula tract after 6-8 weeks. The hepatolithiasis removal, complications and hepatolithiasis recurrence rates, and the cholangio-intestinal anastomotic stenosis rate and treatments were recorded. The follow-up was performed to analyse prognosis.Results:All 95 patients successfully underwent PTOBF rigid choledochoscopy and electronic choledochoscopy via the fistula tract. In 92 patients (96.8%), stones were completely removed. In 3 patients, small amounts of peripheral bile duct stones were left behind. Of 49 patients had cholangio-intestinal anastomotic strictures. On cholangioscopic examination, the strictures were caused by anastomotic knots in the suture line in 25 patients and cicatricial stenosis in 24 patients. After biliary balloon dilation and removal of anastomotic suture line knots, the strictures were relieved in 49 patients. There were 2 patients who developed biliary bleeding and 2 patients pleural effusion after PTOBF rigid choledochoscopy. Hepatolithiasis recurred in 4 patients in 6 to 36 months later.Conclusion:PTOBF followed by two stages cholangioscopic treatment were safe and effective in treatment of type Ⅰ and Ⅱa hepatolithiasis after Roux-en-Y cholangiojejunostomy. A high hepatolithiasis removal rate was obtained. Balloon dilation and removal of biliary intestinal anastomotic suture knots effectively relieved biliary intestinal anastomotic stenosis. The long-term results needs to be further determined.
