ABSTRACT
Objective To observe the clinical features and evaluate the risk factors affecting prognosis in patients with secondary sepsis of gastrointestinal perforation (GIP). Methods A retrospective cohort study was conducted, and the patients with GIP admitted to the Department of General Surgery of Affiliated Shuyang People's Hospital of Xuzhou Medical University from January 1, 2014 to April 30, 2017 were enrolled, according to the presence or absence of sepsis occurrence, they were divided into GIP with and GIP without sepsis groups. The difference of gender, age, the time between the onset of GIP and the occurrence of sepsis, infection situation, body temperature, heart rate, respiratory frequency, white blood cell count (WBC), systemic inflammatory response syndrome (SIRS) in accord with standard, C-reactive protein (CRP), blood sugar, mean arterial pressure (MAP), lactic acid, number of cases having undergone laparoscopic surgery, sequential organ failure score (SOFA) and quick sequential organ failure score (qSOFA), Glasgow coma score(GCS), length of stay in intensive care unit (ICU), the total length of stay in hospital were compared;the status of survival and prognosis was assessed on day 30 by the Glasgow Outcome Scale (GOS). The indicators with statistical significance in the two groups were brought into the Cox regression model to analyze the independent risk factors affecting the prognosis of the patients. Results Fifty-eight patients with GIP were enrolled in this study. Among them, 22 cases developed secondary sepsis (GIP with sepsis group, there were 50.0% cases with single organ failure and 50.0% cases with multiple-organ failure, cases only in accord with 0-1 SIRS criteria accounting for 81.8%, and the mortality of secondary sepsis being 31.8%). No sepsis occurred in 36 patients (GIP without sepsis group). In GIP with sepsis group, the age, blood glucose, lactic acid, SOFA score, qSOFA, and the length of stay in ICU were significantly higher than those of GIP without sepsis group [age (years): 68.7±15.9 vs. 56.1±17.2, blood glucose (mmol/L): 6.9±2.3 vs. 5.9±1.2, lactic acid (mmol/L): 2.9±1.3 vs. 1.2±0.7, SOFA score: 5.6±3.2 vs. 0.5±0.4, qSOFA score: 1.0±0.9 vs. 0.3±0.1, the length of stay in ICU (days): 1.0 (0-4.0) vs. 0.1 (0-2.0), all P < 0.05], while MAP, GCS, and GOS scores in GIP with sepsis group were significantly lower than those in GIP without sepsis group [MAP (mmHg, 1 mmHg =0.133 kPa): 83.6±18.7 vs. 100.0±14.3, GCS score: 12.8±3.5 vs. 14.5±0.5, GOS score: 3.5±1.9 vs. 4.9±0.2, all P < 0.01]. Cox multivariable regression analysis showed: only low MAP and low GCS score were the independent risk predictors of death outcome for GIP with sepsis, the relative risk (RR) was 0.896 [95% confidence interval (CI) = 0.815-0.984, P = 0.022] and 0.585 (95%CI = 0.395-0.866, P = 0.007) respectively. Conclusion Patients with secondary sepsis following GIP have relatively high morbidity and much more risk factors, but only low MAP and low GCS score are closely associated with its high risk of death.

ABSTRACT
A high performance liquid chromatography tandem mass spectrometric ( HPLC-MS/MS ) method was developed for the determination of seven perfluorinated alkyl acidin ( C4-C10 ) and perfluorooctane sulfonate in water. After the particulate was removed by leaching, surrogate standard was added, then the sample was loading to a pre-conditioned WAX cartridge for purification, and then the eluent was concentrated and analyzed by HPLC-MS/MS. Due to the situation that the fluoride polymer was unavoidable to be used in the LC system, a delay column was employed and the perfluorooctanoic acid ( PFOA ) of interference was departed from the PFOA in sample. The method detection limit ( MDL) of PFOA was 0. 8 ng/L, and the lowest quantitative concentration (LQC) was 3. 2 ng/L. For other compounds, the MDL was ranged from 0. 2 to 1. 2 ng/L, and the LQC was 0. 8-4. 8 ng/L. This method also had good reproducibility, for six duplicated samples, the relative standard deviations ( RSD ) of all target compounds were less than 16%. And the recoveries of target compounds at six spiked matrix samples ranged from 87% to 129%, and the RSD were less than 15%. Because of the connection of delay column, the background was well controlled, and a relatively lower MDL were obtained.
