The rapid screening of tumor markers is a challenging task for early diagnosis of cancer. This study aims to use highly sensitive chemiluminescent protein microarray technology to efficiently screen a variety of low abundance tumor related markers. A new material, termed integrated polydimethylsiloxane modified silica gel (iPDMS), was obtained by adding a surface polymerization initiator with olefin end to the conventional polydimethylsiloxane, and fixing into the three-dimensional structure of polydimethylsiloxane by thermal crosslinking through silicon hydrogen bonding. In order to make the iPDMS material resistant to non-specific protein adsorption, a poly(OEGMA) polymer brush was synthesized by surface-initiated atom transfer radical polymerization at the active initiation site. Finally, 20 tumor-related antigens were printed into the specific areas of the microarray by high-throughput spray printing technology, and assembled into 48-well detection microtiterplates of the iPDMS microarray. It was found the VEGFR and VEGF121 autoantibodies that obtained from 8 common tumors (breast cancer, lung cancer, colon cancer, gastric cancer, liver cancer, leukemia, lymphoma and ovarian cancer) can be used as potential tumor markers. The chemiluminescence labeled iPDMS protein microarray can be used for the screening of tumor autoantibodies at early stage.

OBJECTIVETo investigate the predictive value of procalcitonin(PCT) in postoperative intra-abdominal infections (IAI) after definitive operation of intestinal fistulae(IF).
METHODSWith the exclusion of emergence operation, preoperative clinical infection, preoperative renal or hepatic dysfunction, and age less than 18 years, a total of 356 consecutive patients who underwent elective digestive tract reconstruction of intestinal fistulae from February 2012 to December 2015 at Intestinal Fistula Center of Jinling Hospital were prospectively enrolled in the study. All the patients were divided into IAI group (26 cases, 21 of anastomosis leakage and 5 of peritoneal abscess) and non-IAI group (330 cases) based on the existence of postoperative IAI. The non-IAI group was then divided into two subgroups of other infection (93 cases) and non-infection(237 cases) according to the presence of other infections. Plasma PCT level, serum CRP concentration and WBC count were assessed preoperatively and on postoperative days (PODs) 1, 3, 5, 7 by immunofluorescence, turbidimetry and automatic blood analyzer, respectively. The predictive value of each marker for IAI was calculated by receiver operating characteristic (ROC) curve.
RESULTSThere was no significant difference in general clinical data between IAI and non-IAI group (all P>0.05). The proportions of multi-IF (53.8%, 14/26) and colectomy (61.5%, 16/26) in IAI group were higher than those of non-IAI group [20.0% (66/330), χ=15.847, P=0.000 and 31.2%(103/330), χ=9.961, P=0.002]. Differences of preoperative PCT, CRP and WBC levels among IAI, other infection and non-infection groups were not significant. These three markers all increased obviously and immediately after surgery. PCT and WBC values reached the peak point on POD 1, whereas CRP on POD 3. In IAI group, mean PCT values were (5.4±4.2) μg/L, (2.9±1.9) μg/L and (1.6±1.8) μg/L on POD 1, POD 3 and POD 5, respectively, which were higher than those of other infection group [(4.2±8.7) μg/L, (1.9±3.8) μg/L and (0.6±0.8) μg/L] and non-infection group [(2.7±5.8) μg/L, (1.1±1.7) μg/L and (0.5±0.7) μg/L, all P<0.05]. Mean CRP values in IAI group were 99.4 mg/L and 183.9 mg/L respectively on POD 1 and POD 3,and mean WBC values of IAI group on POD 1, POD 3 and POD 5 were 16.0×10/L, 10.8×10/L and 8.7×10/L, respectively, which were all significantly higher than those in the other 2 groups (all P<0.05). No significant differences were obtained between other infection group and non-infection group in all these three markers (all P>0.05). ROC curve demonstrated that PCT had the biggest area under the curve (AUC) of 0.86 and 0.84 on POD 3 and POD 5, with the cut-off value of 0.98 μg/L and 0.83 μg/L, 92.0% sensitivity and 74.0% specificity, 91.0% sensitivity and 73.0% specificity, respectively. The highest AUC was 0.72 on POD 3 for CRP and 0.71 on POD 3 for WBC, with 80.0% sensitivity and 54.0% specificity, 56.0% sensitivity and 73.0% specificity, respectively.
CONCLUSIONThe value of procalcitonin above 0.98 μg/L on POD 3 and 0.83 μg/L on POD 5 can predict the occurrence of IAI after definitive operations of intestinal fistulae.

Chinese Journal of Gastrointestinal Surgery 2016;19(7):743-745
Over the past decades, the evolution of the techniques used in the intensive care has led on one side to better survival rates in ICU patients. On the other side, it has resulted in a growing number of patients who survive an acute event to chronic condition, and who then become dependent on one or more life support treatments. Such patients are called chronic critical illness(CCI) patients. Even these patients can dismiss from intensive care unit (ICU) or transfer to specialized rehabilitation care settings, the mortality of these patients is still very high. Therefore, how to promote the rehabilitation of CCI patients is one of the most important research points of epidemiology, public health and social economics. Exercise training can promote rehabilitation, improve quality of life and independent functional status in these patients, which should be used as one of the standard treatment protocols for CCI patients.

BACKGROUNDThe clinical applications of fibrin glue span over several surgical modalities. The aim of this study was to evaluate the biocompatibility and biodegradation of different formulations of platelet-rich fibrin glue in vivo and examine its effects on the neovascularization of wound sites.
METHODSHuman-derived single-unit fibrin glue was prepared. Incisions were made on the backs of rats, and these were coated with homemade glues containing different concentrations of aminomethylbenzoic acid (Groups A-F) or commercial adhesives (Group G). A sham control group was included (Group H). The wounds were examined by histological analysis and immunohistochemistry at several time points.
RESULTSSuccessful wound closure was achieved in all groups by day 12. Acute inflammation occurred during the first six days, but gradually disappeared. The longest sealant duration was achieved using the lowest concentration of anti-fibrinolytic agent in a 1:10 volume ratio with cryoprecipitate. Expression levels of the platelet endothelial cell adhesion molecule-1 were significantly higher in Groups A and C compared to the control groups (Groups G and H) on day 3 (P < 0.05).
CONCLUSIONSSingle-unit platelet-rich fibrin glue has excellent biocompatibility and is associated with the upregulation of neovascularization. The addition of aminomethylbenzoic acid could prevent the degradation of fibrin glue.
