Objective To determine plasma resistin level in patients with traumatic brain injury (TBI) and evaluate its correlations with outcome and inflammatory reaction. Methods Fiftyfour patients with moderate TBI, 71 patients with severe TBI and 40 healthy controls were enrolled in this study. Plasma samples were obtained from the healthy controls on physical examination and from the TBI patients on admission. Enzyme-linked immunosorbent assay ( ELISA) was used to determine the plasma resistin concentrations. Results Twenty patients (37.0% ) and 53 patients (74.6% ) with moderate and severe TBI suffered from an unfavorable outcome (defined as GOS score for 1-3 points) three months after TBI respectively. Plasma resistin levels in the patients with moderate and severe TBI were substantially higher than that in the healthy controls ((21. 9 ± 8. 4) ng/ml and (29. 2 ± 9. 6) ng/ml vs (9. 3 ± 2.6) ng/ml, both P ＜0. 01] by using covariance analysis. By using the multivariate linear regression analysis, plasma C-reactive protein level (t =2.212,P =0.035; t =2. 274,P =0. 014) and GCS scores (t =3. 120,P =0.007; t=3.986,P=0.003) were associated with the plasma resistin levels. Logistic regression analysis selected plasma resistin level as an independent predictor for 3-month unfavorable outcome of the patients with moderate and severe TBI (odds ratio = 1. 124, 95% CI = 1. 040-1. 221, P = 0.011; odds ratio = 1. 145, 95% CI = 1. 044-1. 232, P = 0. 009). A receiver operating characteristic curve identified cutoff levels of plasma resistin (22.4 ng/ml and 30.5 ng/ml) that predicted 3-month unfavorable outcome of moderate and severe TBI patients with the high sensitivity (70. 0% and 79. 2% ) and specificity (70.6% and 72.2% ) ( area under curve = 0.719, 95% CI = 0.642-0.829, P = 0.000;area under curve =0.735, 95% CI =0. 671-0. 893, P = 0.000). Conclusions Plasma resistin level is increased after TBI and may be involved in inflammatory response of brain injury. Clinical detection of this indicator can help early determine the prognosis of the TBI patients.

Objective To investigate the efficacy and safety of endoscopic ultrasound-guided gallbladder drainage ( EUS-GBD) for patients with acute cholecystitis, who are unfit for cholecystectomy. Methods Patients who underwent EUS-GBD at Hangzhou First People′s Hospital from April 2015 to December 2016 were enrolled in this study. Clinical data were collected, and effectiveness and complications were analyzed. Results EUS-GBD was achieved in all 5 patients, and the mean procedure time of EUS-GBD was 26. 0±3. 1 min. Double pigtail plastic stents were successfully placed in 4 patients. A nasobiliary drainage tube was placed in 1 patient and the tube was endoscopically cut 5 days after procedure acting as internal drainage. All patients recovered without complications and no procedure-related death occurred. During the follow-up period (46-692 d), no patient experienced recurrent cholecystitis and stent migration. Conclusion At an experienced endoscopic center, EUS-GBD is a safe, effective and minimally invasive method for patients with acute cholecystitis and high surgical risk.

Objective:To evaluate endoscopic nasobiliary drainage (ENBD) combined with nasojejunal tube feeding for elderly patients with severe acute cholangitis.Methods:Data of 43 elderly patients with severe acute cholangitis, who received ENBD combined with nasojejunal tube feeding from January 1, 2016 to May 31, 2018 at Affiliated Hangzhou First People′s Hospital, Zhejiang University School of Medicine were retrospectively analyzed and were included in the observation group, and 43 other patients who received ENBD combined with conventional therapy in the same period were included in the control group with the matching principle of 1∶1. Liver function indices (ALT and AST), nutritional status (Hb, TP and ALB) and inflammation indices (WBC, NEU% and CRP) of the two groups before the operation, 3 days and 7 days of nutritional support after the operation were compared. Adverse reactions (abdominal distention and diarrhea), mortality, hospitalization time and expenses of the two groups were also compared.Results:There were no significant differences in gender composition, mean age, preoperative APACHE-Ⅱ score, NRS2002 score, liver function index, nutritional index, or inflammatory index between the observation group and the control group ( P>0.05). The baseline data of the two groups were comparable. After 3 days of nutritional support, ALT, AST, TP were 21.0 (15.0, 35.5) U/L, 26.0 (21.0, 36.5) U/L, and 64.2±5.2 g/L, respectively in the observation group, and 47.0 (29.5, 82.5) U/L ( P<0.05), 47.0 (29.0, 75.0) U/L ( P<0.05), and 60.5±6.4 g/L ( P<0.05), respectively in the control group. The levels of other indicators were not statistically different at this time point ( P>0.05). At 7 days postoperative nutritional support, ALT, AST, TP, ALB and CRP of the observation group were 22.0 (14.0, 31.5) U/L, 26.0 (20.5, 38.5) U/L, 67.6±5.4 g/L, 34.6±3.7 g/L, and 28.0 (18.5, 35.5) mg/L, respectively, and 43.0 (18.0, 59.5) U/L ( P<0.01), 34.0 (24.0, 60.5) U/L ( P=0.02), 64.5±5.7 g/L ( P=0.01), 31.5±7.0 g/L ( P=0.02), and 34.0 (24.0, 66.5) mg/L ( P<0.05) in the control group. There were no significant differences in the levels of other indicators between the two groups at this time point ( P>0.05). In the observation group, the incidence of diarrhea, abdominal distension, mortality, hospitalization time and hospitalization expenses were 32.6% (14/43), 30.2% (13/43), 9.3% (4/43), 16.0±7.0 days and 40±10 thousand yuan, respectively, and in the control group, the above indicators were 4.7% (2/43) ( P<0.05), 7.0% (3/43) ( P<0.05), 11.6% (5/43) ( P=0.72), 19.3±3.7 days ( P<0.05)) and 53±23 thousand yuan ( P<0.05), respectively. Conclusion:For elderly patients with severe acute cholangitis, enteral nutrition with ENBD can effectively improve the nutritional status, reduce inflammatory reaction, the impact on liver function, and hospital costs, and shorten the hospitalization time, which is suitable for further clinical application.
