Objective:Surgical site infection (SSI) is the most common infectious complication after emergency abdominal surgery (EAS). To a large extent, most SSI can be prevented, but there are few relevant studies in China. This study mainly investigated the current situation of SSI occurrence after EAS in China, and further explored risk factors for SSI occurrence.Methods:Multi-center cross-sectional study was conducted. Clinical data of patients undergoing EAS in 33 hospitals across China between May 1, 2019 and June 7, 2019 were prospectively collected, including perioperative data and microbial culture results from infected incisions. The primary outcome was the incidence of SSI after EAS, while the secondary outcomes were postoperative hospital stay, ICU occupancy rate, length of ICU stay, hospitalization cost, and mortality within postoperative 30 days. Univariate and multivariate logistic regression models were used to analyze the risk factors of SSI after EAS.Results:A total of 660 EAS patients aged (47.9±18.3) years were enrolled in this study, including 56.5% of males (373/660). Forty-nine (7.4%) patients developed postoperative SSI. The main pathogen of SSI was Escherichia coli [culture positive rate was 32.7% (16/49)]. As compared to patients without SSI, those with SSI were more likely to be older (median 56 years vs. 46 years, U=19 973.5, P<0.001), male [71.4% (35/49) vs. 56.1% (343/611), χ 2=4.334, P=0.037] and diabetes [14.3% (7/49) vs. 5.1% (31/611), χ 2=5.498, P=0.015]; with-lower preoperative hemoglobin (median: 122.0 g/L vs. 143.5 g/L, U=11 471.5, P=0.006) and albumin (median: 35.5 g/L vs. 40.8 g/L, U=9452.0, P<0.001), with higher blood glucose (median: 6.9 mmol/L vs. 6.0 mmol/L, U=17 754.5, P<0.001); with intestinal obstruction [32.7% (16/49) vs. 9.2% (56/611), χ 2=25.749, P<0.001], with ASA score 3-4 [42.9% (21/49) vs. 13.9% (85/611), χ 2=25.563, P<0.001] and with high surgical risk [49.0% (24/49) vs. 7.0% (43/611), χ 2=105.301, P<0.001]. The main operative procedure resulting in SSI was laparotomy [81.6%(40/49) vs. 35.7%(218/611), χ 2=40.232, P<0.001]. Patients with SSI experienced significantly longer operation time (median: 150 minutes vs. 75 minutes, U=25 183.5, P<0.001). In terms of clinical outcome, higher ICU occupancy rate [51.0% (25/49) vs. 19.5% (119/611), χ 2=26.461, P<0.001], more hospitalization costs (median: 44 000 yuan vs. 15 000 yuan, U=24 660.0, P<0.001), longer postoperative hospital stay (median: 10 days vs. 5 days, U=23 100.0, P<0.001) and longer ICU occupancy time (median: 0 days vs. 0 days, U=19 541.5, P<0.001) were found in the SSI group. Multivariate logistic regression analysis showed that the elderly (OR=3.253, 95% CI: 1.178-8.985, P=0.023), colorectal surgery (OR=9.156, 95% CI: 3.655-22.937, P<0.001) and longer operation time (OR=15.912, 95% CI:6.858-36.916, P<0.001) were independent risk factors of SSI, while the laparoscopic surgery (OR=0.288, 95% CI: 0.119-0.694, P=0.006) was an independent protective factor for SSI. Conclusions:For patients undergoing EAS, attention should be paid to middle-aged and elderly patients and those of colorectal surgery. Laparoscopic surgery should be adopted when feasible and the operation time should be minimized, so as to reduce the incidence of SSI and to reduce the burden on patients and medical institutions.

Objective: To investigate the diagnosis and treatment for enterocutaneous fistula (ECF) in China, and to explore the prognostic factors of ECF. Methods: A multi-center cross-sectional study was conducted based on the Registration System of Chinese Gastrointestinal Fistula and Intra-Abdominal Infections to collect the clinical data of ECF patients from 54 medical centers in 22 provinces/municipalities from January 1, 2018 to December 31, 2018. The clinical data included patient gender, age, length of hospital stay, intensive care unit (ICU) admission, underlying diseases, primary diseases, direct causes of ECF, location and type of ECF, complications, treatment and outcomes. All medical records were carefully filled in by the attending physicians, and then re-examined by more than two specialists. The diagnosis of ECF was based on the clinical manifestations, laboratory/imaging findings and intraoperative exploration. Results: A total of 1521 patients with ECF were enrolled, including 1099 males and 422 females, with a median age of 55 years. The top three primary diseases of ECF were malignant tumors in 626 cases (41.2%, including 540 gastrointestinal tumors, accounting for 86.3% of malignant tumors), gastrointestinal ulcers and perforations in 202 cases (13.3%), and trauma in 157 cases (10.3%). The direct causes of ECF were mainly surgical operation in 1194 cases (78.5%), followed by trauma in 156 (10.3%), spontaneous fistula due to Crohn′s disease in 92 (6.0%), radiation intestinal injury in 41 (2.7%), severe pancreatitis in 20 (1.3%), endoscopic treatment in 13 (0.9%) and 5 cases (0.3%) of unknown reasons. All the patients were divided into three groups: 1350 cases (88.7%) with simple ECF, 150 (9.9%) with multiple ECF, and 21 (1.4%) with combined internal fistula. Among the patients with simple ECF, 438 cases (28.8%) were jejuno-ileal fistula, 313 (20.6%) colon fistula, 170 (11.2%) rectal fistula, 111 (7.3%) duodenal fistula, 76 (5.0%) ileocecal fistula, 65 (4.3%) ileocolic anastomotic fistula, 55 (3.6%) duodenal stump fistula, 36 (2.4%) gastrointestinal anastomotic fistula, 36 (2.4%) esophagogastric/esophagojejunal anastomotic fistula, 29 (1.9%) gastric fistula and 21 (1.4%) cholangiopancreatiointestinal. Among all the simple ECF patients, 991 were tubular fistula and 359 were labial fistula. A total of 1146 patients finished the treatment, of whom 1061 (92.6%) were healed (586 by surgery and 475 self-healing) and 85 (7.4%) died. A total of 1043 patients (91.0%) received nutritional support therapy, and 77 (6.7%) received fistuloclysis. Infectious source control procedures were applied to 1042 patients, including 711 (62.0%) with active lavage and drainage and 331 (28.9%) with passive drainage. Among them, 841 patients (73.4%) underwent minimally invasive procedures of infectious source control (replacement of drainage tube through sinus tract, puncture drainage, etc.), 201 (17.5%) underwent laparotomy drainage, while 104 (9.1%) did not undergo any drainage measures. A total of 610 patients (53.2%) received definitive operation, 24 patients died within postoperative 30-day with mortality of 3.9% (24/610), 69 (11.3%) developed surgical site infection (SSI), and 24 (3.9%) had a relapse of fistula. The highest cure rate was achieved in ileocecal fistula (100%), followed by rectal fistula (96.2%, 128/133) and duodenal stump fistula (95.7%,44/46). The highest mortality was found in combined internal fistula (3/12) and no death in ileocecal fistula. Univariate prognostic analysis showed that primary diseases as Crohn′s disease (χ²=6.570, P=0.010) and appendicitis/appendiceal abscess (P=0.012), intestinal fistula combining with internal fistula (χ²=5.460, P=0.019), multiple ECF (χ²=7.135, P=0.008), esophagogastric / esophagojejunal anastomotic fistula (χ²=9.501, P=0.002), ECF at ileocecal junction (P=0.012), non-drainage/passive drainage before the diagnosis of intestinal fistula (χ²=9.688, P=0.008), non-drainage/passive drainage after the diagnosis of intestinal fistula (χ²=9.711, P=0.008), complicating with multiple organ dysfunction syndrome (MODS) (χ²=179.699, P<0.001), sepsis (χ²=211.851, P<0.001), hemorrhage (χ²=85.300, P<0.001), pulmonary infection (χ²=60.096, P<0.001), catheter-associated infection (χ²=10.617, P=0.001) and malnutrition (χ²=21.199, P<0.001) were associated with mortality. Multivariate prognostic analysis cofirmed that sepsis (OR=7.103, 95%CI:3.694-13.657, P<0.001), complicating with MODS (OR=5.018, 95%CI:2.170-11.604, P<0.001), and hemorrhage (OR=4.703, 95%CI: 2.300-9.618, P<0.001) were independent risk factors of the death for ECF patients. Meanwhile, active lavage and drainage after the definite ECF diagnosis was the protective factor (OR=0.223, 95%CI: 0.067-0.745, P=0.015). Conclusions The overall mortality of ECF is still high. Surgical operation is the most common cause of ECF. Complications e.g. sepsis, MODS, hemorrhage, and catheter-associated infection, are the main causes of death. Active lavage and drainage is important to improve the prognosis of ECF.

This study showed a case of a patient with central dislocation of the femoral head without involvement of anterior or posterior column of the acetabulum. The patient was associated with endocrine disorders caused by pituitectomy, severe osteoporosis caused by a long-term gulucocorticoids intake history, and poor bone quality of the quadrilateral plate. The direct impact of the femoral head on the quadrilateral plate after trauma resulted in purely central dislocation of the femoral head. 3D printing technique was used to print the fracture model for observation of the fracture morphology and the simulated operation before surgery. The variable-angle locking acetabular plate with a propeller-like shape was designed on the basis of the mirror of the ipsilesional semi-pelvis. This fracture was reduced via the lateral-rectus approach under direct vision. The quadrilateral surface fractures were fixed by the variable-angle locking acetabular plate which was used as a template for reduction. The follow up after surgery showed good reduction and fixation, equal length of double lower limbs, good positive and passive motion of the injured hip joint and without perioperative complications. This report describes an isolated quadrilateral plate fracture that has not yet been classified. It was effectively treated by using a customized variable-angle locking acetabular plate with a propeller-like shape via the lateral rectus approach.

Objective: To evaluate clinical efficacy and surgical techniques of customized variable-angle locking acetabular wing plates in treatment of complex acetabular fractures in the elderly through the lateral-rectus approach. Methods: Data of 11 elder patients of complex acetabular fractures (mean age 75 y, range: 60-93 y; 8 males, 3 females) admitted to our department from March 2016 to March 2017 were retrospectively analyzed. According to Judet-Letournel classification of acetabular fractures, there were 2 cases of anterior column and posterior hemitransverse fractures, 9 cases of both-column fractures. The customized variable-angle locking acetabular wing plates were designed by mimics software and then produced before surgery. During the operation, the customized variable-angle locking acetabular wing plate was applied to reduction and fixation via the anterior lataral-rectus approach. The effect of fracture reduction was assessed by Matta's criteria. The clinical effect was assessed by Harris Hip score and the modified Merle d' Aubigné-Postal score at the 6th month of postoperative follow-up. Results: The average time of designing and producing customized variable-angle locking acetabular wing plates was 4 d (3-5 d), the average operation time was 95 min (45-150 min), and the average intraoperative bleeding was 600 ml (250-1 400 ml). All patients were followed up, with an average follow-up of 18 m (6-24 m). All fractures were healed, with an average healing time of 8 weeks (6-12 weeks). Reduction quality: excellent in 8 cases, good in 2 cases, poor in 1 case, with an overall excellent and good rate of 90.9%. The result of Harris Hip scoring: excellent in 7 cases, good in 3 cases, and acceptable in 1 case, with a total excellent and good rate of 90.9%; Modified Merle d' Aubigné-Postal soring: excellent in 6 cases, good in 3 cases, and acceptable in 2 cases, with an overall excellent and good rate of 81.8%. There were 2 cases of obturator nerve injury, 1 case of fat liquefaction of incision, 3 cases of traumatic hip arthritis. During the follow-up, no complications such as ectopic ossification, plate fracture and screw loosening were found. Conclusion The customized variable-angle locking acetabular wing plates in treatment of complex acetabular fractures in the elderly via the lateral-rectus approach can achieve satisfactory reduction and firm fixtation.

PURPOSE: Nonylphenol (NP) is an endocrine disruptor found in products such as cleaners, plastics, and detergents. It exerts actions similar to endogenous 17β-estradiol (E2) and is reported to influence various cancers. However, its role in colon cancer remains elusive. MATERIALS AND METHODS: Colon cancer cell lines COLO 205 and SW480 were employed in our study. The cells were treated with NP or E2 followed by measurement of apoptosis and proliferation using flow cytometry and MTT assays, respectively. G protein–coupled estrogen receptor 30 (GPR30) expression was visualized using immunofluorescence and Western blot. To investigate the underlying mechanism, the expression levels of GPR30, p-protein kinase A (PKA), c-myc, cyclin D1, and ERK1/2 were analyzed using Western blot. Meanwhile, the GPR30 antagonist G15 was utilized to validate the role of GPR30 in colon cancer progression. Finally, the effect of a GPR30 inhibitor on tumor growth was determined in vivo using tumor xenograft mouse models. RESULTS: NP facilitated the proliferation of colon cancer cells and induced apoptosis failure in vitro. Western blot revealed increased GPR30 expression levels in response to NP treatment. Cyclin D1, p-PKA, c-myc, and proliferating cell nuclear antigen, proteins that regulate the cell cycle, were all upregulated by NP, and NP-mediated ERK1/2 activation and subsequent cell proliferation were abrogated by the GPR30 inhibitor G15. Moreover, colon cancer mice that received G15 administration demonstrated impaired tumor growth in vivo. CONCLUSION: Low dose NP promotes the growth of colon tumors through GPR30-mediated activation of ERK1/2 signaling.

OBJECTIVETo investigate the expression and the subcellular localization of HDAC9 in different brain regions of mice after cerebral ischemic injury and explore the association between HDAC9 and ischemic stroke.

METHODSTwenty-one male C57BL/6 mice were randomly divided into sham-operated group (n=9) and operated group (n=12). In the latter group, the mice with Zea-Longa neurological deficit scores of 2 or 3 following middle cerebral artery occlusion (MCAO) were assigned into MCAO group (n=9). Immunofluorescence was performed to investigate the subcellular localization of HDAC9 in the brain tissues on day 3 after MCAO. Western blotting and qRT-PCR were used to analyze the expression of HDAC9 in different regions of the brain. Results Immunofluorescence showed more intense HDAC9 expressions in the brain tissues around the infarct focus, and in the cells surrounding the infarct, HDAC9 expression was obviously increased in the cytoplasm and reduced in the cell nuclei. Compared with the other brain regions, the ipsilesional cortex with MCAO showed more abundant HDAC9 expressions at both the mRNA and protein levels (P<0.05).

CONCLUSIONHDAC9 may be closely related to cerebral ischemic injury and participate in the pathophysiological process of ischemic stroke.

Objective To evaluate the clinical outcome of bleeding control by preoperative embolization of internal iliac artery with DSA and intra?operative presetting abdominal aorta balloon, combine with the operation techniques of exposure, reduc?tion and internal fixation of pelvic fracture through lateral?rectus approach. Methods From March 2012 to May 2015, 7 patients with type C3 pelvic fractures admitted to our department from March 2012 to May 2015, treated with preoperative embolization of internal iliac artery under digital subtraction angiography 2 h before surgery and presetting abdominal aorta balloon were retrospec?tively reviewed. There were 3 males and 4 females, with an average age of 34 years (range, 16 to 61 years). According to AO classi?fication, all 7 cases belonged to type C3 (3.2:5 cases;C3.3:2 cases), including 5 cases with limb fracture, 2 cases with craniocere?bral trauma, 4 cases with pulmonary contusion, 2 cases with injury of abdominsal organs. Time from injury to operation was 19 days on average (10 to 33 days). Patients received damage control surgery treatment including bleeding control and temporary ex?ternal fixation, and ipsilateral tractions with heavy weight, intensive care and corrections of general situation before operation. The fracture model was manufactured by 3D printing and fracture reduction was simulated on computer preoperatively. Embolization of internal iliac artery was performed in the side of severe displaced sacroiliac joint with DSA 2 hours preoperatively. Reduction was performed to stabilize anterior-posterior pelvic ring and acetabular fractures via the intraoperative lateral?rectus approach. And 2 cases were performed by temporary balloon occlusion of abdominal aorta (≤60 min) for bleeding control in reduction of in the side of sacroiliac joint fractures. Results All the 7 cases had undergone the operations successfully, and the operating time was from 135-320 min with blood loss from 440-3 350 ml. According to Matta radiological evaluation postoperatively, reduction of pelvic fracture was rated as anatomic in 5 cases, satisfactory in 2, without complications. All 7 cases were complicated with lumbosacral plexus injury or lumbosacral trunk injury at different degrees (M0 2 cases, M1 2 cases, M2 2 cases, M3 1 case). According to the BMRC scoring system, 5 cases had well recovered and the other 2 cases had no improvement after three months (M4 2 cases, M5 3 cases). Conclusion Surgical management of pelvic fracture through preoperative internal iliac artery embolization and intra?oper?ative occlusion of abdominal aorta could effective control bleeding and achieve favorable conditions for reduction. Lateral?rectus approach can provide adequate exposure of the anterior and posterior ring, and this approach could also provide excellent visual control of reduction and fixation.
