ABSTRACT

Colonic interposition is the main procedure used in esophageal reconstruction. We report a rare case of simultaneous treatment of an anastomotic site stricture and a neoplasm in the interpositioned colon. A 69-year-old female visited our outpatient clinic with symptoms of progressive dysphagia for 1 year. At the age of 30 years, the patient underwent esophagectomy with retrosternal colonic interposition because of severe esophageal burns after chemical ingestion. Upper gastrointestinal endoscopy revealed stricture at the anastomosis site and a 10-mm flat elevated high-grade dysplasia in the interpositioned colon. First, through-the-scope balloon dilatation was performed for strictures. However, stenosis was observed during the second upper gastrointestinal endoscopy session.Therefore, a second session of through-the-scope balloon dilatation was performed, and simultaneously, endoscopic submucosal dissection was also successfully performed. After 2 months of follow-up, stenosis persisted; consequently, balloon dilatation was performed. No recurrence of neoplasm was confirmed endoscopically. Through-the-scope balloon dilatation of the stricture site and simultaneous endoscopic submucosal dissection of the neoplasm in the interpositioned colon were successfully performed.

ABSTRACT

Objective: To verify the feasibility and accuracy of the transanal multipoint full-layer puncture biopsy (TMFP) technique in determining the residual status of cancer foci after neoadjuvant therapy (nCRT) in rectal cancer. Methods: Between April 2020 and November 2022, a total of 78 patients from the Beijing Chaoyang Hospital of Capital Medical University, the Beijing Friendship Hospital of Capital Medical University, the Qilu Hospital of Shandong University, the Zhongnan Hospital of Wuhan University with advanced rectal cancer received TMFP after nCRT participated in this prospective multicenter trial. There were 53 males and 25 females, aged (M(IQR)) 61 (13) years (range: 35 to 77 years). The tumor distance from the anal verge was 5 (3) cm (range: 2 to 10 cm). The waiting time between nCRT and TMFP was 73 (26) days (range: 33 to 330 days). 13-point transanal puncture was performed with a 16 G tissue biopsy needle with the residual lesion as the center. The specimens were submitted for independent examination and the complications of the puncture were recorded. The consistency of TMFP and radical operation specimen was compared. The consistency of TMPF with clinical remission rates for the diagnosis of complete pathological remission was compared by sensitivity, specificity, negative predictive value, positive predictive value and accuracy. Statistical analysis between groups was performed using the χ2 analysis, and a paired χ2 test was used to compare diagnostic validity. Results: Before TMFP, clinical complete response (cCR) was evaluated in 27 cases. Thirty-six cases received in vivo puncture, the number of punctures in each patient was 13 (8) (range: 4 to 20), 24 cases of tumor residue were found in the puncture specimens. The sensitivity to judgment (100% vs. 60%, χ2=17.500, P<0.01) and accuracy (88.5% vs. 74.4%, χ2=5.125, P=0.024) of TMFP for the pathologic complete response (pCR) were significantly higher than those of cCR. Implement TMFP based on cCR judgment, the accuracy increased from 74.4% to 92.6% (χ2=4.026, P=0.045). The accuracy of the in vivo puncture was 94.4%, which was 83.3% of the in vitro puncture (χ2=1.382, P=0.240). Overall, the accuracy of TMFP improved gradually with an increasing number of cases (χ2=7.112, P=0.029). Conclusion: TMFP is safe and feasible, which improves the sensitivity and accuracy of rectal cancer pCR determination after nCRT, provides a pathological basis for cCR determination, and contributes to the safe development of the watch and wait policy.

ABSTRACT

Objective: To compare the long-term outcomes of intersphincteric (trans-internal and external) sphincter resection (ISR) and abdominoperineal proctocolectomy (APR) for low-grade rectal cancer. Methods: We used a meta-analytic approach to compare these procedures . Published reports comparing ISR and APR for low rectal cancer in Pubmed, Medline, EMBASE and Cochrane, China Knowledge Network (CNKI), China Biomedical Literature Database, and Vipers databases between January 2005 and January 2023 were searched and those meeting the eligibility criteria were selected for extraction of data for analysis. Inclusion criteria were as follows: (1) all reports comparing ISR and APR for low rectal cancer before January 2023; and (2) prospective randomized controlled studies or well-designed cohort studies. Exclusion criteria were as follows: (1) full text not available; (2) duplicate publications, missing primary outcome indicators, and unknown data; and (3) invalid statistical analysis. Results: Sixteen studies with 2498 patients were included in this study. Compared with the APR group, patients in the ISR group were relatively younger (weighted mean difference [WMD]=-1.82, 95%CI=-2.94 to -0.70, P=0.01), had tumors farther from the anal verge (WMD=0.43, 95%CI=0.18 to 0.67, P<0.01), and lower pathological T-stage (T3-4 stage: OR=0.54, 95%CI=0.36 to 0.81, P<0.01). In contrast, there were no statistically significant differences between the two groups in gender (P=0.78), body mass index (P=0.77), or pathological N stage (P=0.09). Compared with the APR group, patients in the ISR group had a lower rate of postoperative complications (OR=0.77, 95%CI=0.60 to 0.99, P=0.04), shorter hospital stay (WMD=-4.30, 95%CI=-7.07 to -1.53, P<0.01), higher 5-year overall survival (HR=0.54, 95%CI=0.33 to 0.88, P=0.01), and higher 5-year disease-free survival (HR=0.65, 95%CI=0.47 to 0.90, P<0.01). Five-year locoregional failure (HR=0.66, 95%CI=0.40 to 1.10, P=0.11) and time to surgery (WMD=-9.71, 95%CI=-41.89 to 22.47, P=0.55) did not differ significantly between the two groups. Conclusion: ISR is a safe and effective alternative to APR for early-stage low-grade rectal cancer.

ABSTRACT

Currently, the standard of clinical complete response (cCR) after neoadjuvant chemoradiotherapy (nCRT) for local advanced rectal cancer generally lacks pathological examination, the cCR judged by the current standard is still far from the real pathological complete response. After nCRT, due to the presence of tissue edema and fibrosis, MRI is highly uncertain in determining the staging of local lesions. The precision of colonoscopy biopsy is generally low because residual cancer foci exist primarily in the muscular layer, which limits the determination of cCR by colonoscopy biopsy. Local excision through the anus can resect the whole intestinal wall tissue, which is relatively accurate and close to the real state of remission of the lesion, but there are many problems, such as affecting anal function, high rate of complications, and increased difficulty of following radical surgery. Based on the present diagnosis of cCR, the authors put forward the concept of modified cCR (m-cCR) which combined with the pathological standard of transanal multipoint full-layer puncture biopsy. It is possible to improve the accuracy of cCR, and improve the safety of cCR patients who receive wait-and-watch therapy without increasing complications or affecting anal function. The exact conclusion needs to be confirmed by further studies.

ABSTRACT

Objective:colorectal cancer is one of the common malignant tumors in the gas-trointestinal tract.Oxaliplatin is the first-line drug for the treatment of advanced colorectal cancer,but drug resistance often occurs.The mechanism of CXCR4 in oxaliplatin resistance of colon cancer is not clear.This study intends to explore the mechanism of CXCR4 mediated oxaliplatin resistance and the potential therapeutic value of CXCR4 inhibitor AMD3100.Methods:oxaliplatin resistant strains HCT116 were constructed.The expression of CXCR4 and the phosphorylation level of PI3K-Akt signal pathway were detected by Q-PCR and Western blot.The phosphorylation level of PI3K-Akt signal pathway was detected by Q-PCR and Western blot.The effect of AMD3100 an-tagonizing CXCR4 or combined application of Akt inhibitor LY294002 on oxaliplatin resistance of drug-resistant cells was detected by CCK8.Results:CCK-8 was used to detect the proliferation activity of Oxaliplatin in HCT116 drug resistant group compared with control cells in the absence of drugs and at different concentrations.The results showed that there was no significant change in the activity of the resistant strains,while the control cells showed a significant decrease.Q-PCR and Western blot showed that the expression of CXCR4 and the phosphorylation level of PI3K-Akt increased significantly in the drug-resistant group(P<0.05).After administration of CXCR4 inhibitor AMD3100,CXCR4 expression and PI3K-Akt phosphorylation decreased significantly(P<0.05).AMD3100 enhanced the sensitivity of drug-resistant cell lines to oxaliplatin.The combination of AMD3100 and Akt inhibitor LY294002 can further enhance the sensitivity of drug-resistant cell lines to oxaliplatin.Conclusion:CXCR4 mediated activation of PI3K-Akt signaling pathway plays an important role in the resistance of colon cancer to oxaliplatin.AMD3100 may become a potential therapeutic drug against chemoresistance of colon cancer.

ABSTRACT

In the mating of filamentous basidiomycetes, dikaryotic mycelia are generated through the reciprocal movement of nuclei to a monokaryotic cytoplasm where a nucleus of compatible mating type resides, resulting in the establishment of two different dikaryotic strains having the same nuclei but different mitochondria. To better understand the role of mitochondria in mushrooms, we created four sets of dikaryotic strains of Lentinula edodes, including B2 × E13 (B2 side) and B2 × E13 (E13 side), B5 × E13 (B5 side) and B5 × E13 (E13 side), E8 × H3 (E8 side) and E8 × H3 (H3 side), and K3 × H3 (K3 side) and K3 × H3 (H3 side). The karyotypes and mitochondrial types of the dikaryotic strains were successfully identified by the A mating type markers and the mitochondrial variable length tandem repeat markers, respectively. Comparative analyses of the dikaryotic strains on the mycelial growth, substrate browning, fruiting characteristics, and mitochondrial gene expression revealed that certain mitochondria are more effective in the mycelial growth and the production of fruiting body, possibly through the activated energy metabolism. Our findings indicate that mitochondria affect the physiology of dikaryotic strains having the same nuclear information and therefore a selection strategy aimed at mitochondrial function is needed in the development of new mushroom strain.

ABSTRACT

ObjectiveTo explore the effect of Ganshuang granule on liver fibrosis (S1 and S2) in chronic hepatitis B (CHB) with liver depression spleen deficiency and blood stasis syndrome. MethodA total of 100 patients were classified into the control group (50 in total with 4 lost and 2 rejected, 44 finally included) and observation group (50 in total with 5 lost and 2 rejected, 43 finally included) with the random number table method. Both groups were given oral entecavir tablets (0.5 mg/time, once a day, 12 months), and oral glutathione tablets was applied depending on the conditions of patients. In addition, the control group took the analog drug of Ganshuang granule (3 g/time, 3 times/day, 12 months) and the observation group received Ganshuang granules (3 g/time, 3 times/day, 12 months), followed by histological examination of the liver by puncture biopsy. The two groups were compared in terms of inflammatory activity grade and fibrosis stage, as well as liver stiffness measure (LSM), liver function, hepatitis B virus (HBV) DNA, liver depression and spleen deficiency syndrome score, aspartate aminotransferase (AST)-to-platelet ratio index (APRI), and fibrosis index based on the four factors (FIB-4). ResultAfter treatment, liver fibrosis in the observation group was milder than that in the control group (P<0.05) and the inflammatory activity grade in the observation group was lower than that in the control group (P<0.05). The effective rate in down-regulating inflammatory activity grade in the observation group was 77.78% as compared with the 45.83% in the control group (χ2=5.546, P<0.05). The effective rate in decreasing the fibrosis stage in the observation group was 59.26%, which was higher than that (16.67%) in the control group (χ2=9.669, P<0.01). The LSM and score of the liver stagnation and spleen deficiency syndrome in the observation group were lower than those in the control group at the 6th months and 12th months of treatment (P<0.05,P<0.01). The levels of alanine aminotransferase (ALT), AST, and alkaline phosphatase (ALP) in the observation group were lower than those in the control group (P<0.01). The APRI and FIB-4 in the observation group were lower than those in the control group (P<0.01). ConclusionThe Ganshuang granule combined with entecavir can alleviate inflammation and liver fibrosis, delay and reverse liver fibrosis, protect liver, and improve the traditional Chinese medicine syndrome of liver fibrosis (S1 and S2) in CHB, which is worth of clinical use and further research.

ABSTRACT

Hereditary colorectal cancer accounts for approximately 5% of all colorectal cancer cases, mainly including familial adenomatous polyposis and Lynch syndrome. Total proctocolectomy plus ileal pouch-anal anastomosis and total colectomy plus ileorectal anastomosis are two major procedures for familial adenomatous polyposis, however, the exact impact of these two procedures on surgical efficacy, oncologic efficacy as well as functional results still remains uncertain. Segmental colectomy and total colectomy are two major procedures for Lynch syndrome, each of them both has advantages and disadvantages, and there still lacks a consensus about the optimal strategy because of the nature of retrospective study with a relatively insufficient evidence support. As a result, we would make a review about the current surgical treatment status and future perspectives of hereditary colorectal cancer.

ABSTRACT

Objective: To compare the effects of 3 treatment strategies (emergent surgery, self-expanding metallic stents, self-expanding metallic stents plus neoadjuvant chemotherapy) on postoperative anal function and quality of life in patients with complete obstructive left hemicolon cancer. Methods: A retrospective cohort study was conducted. Clinical data of patients with complete obstructive left hemicolon cancer admitted to General Surgery Department of Beijing Chaoyang Hospital between January 2017 and October 2019 were retrospectively collected. Patient inclusion criteria: (1) complete obstructive left hemicolon cancer was confirmed through clinical manifestation and abdominal computed tomography; (2) adenocarcinoma was confirmed by postoperative pathology; (3) emergent radical resection of primary tumor was performed with temporary stoma, or radical resection of primary tumor and primary anastomosis was performed without stoma, 7 to 14 days after completion of insertion of self-expanding metallic stents. Patients who did not receive stoma reversion after emergent operation were excluded. According to different therapies, patients were divided into three groups: emergent surgery (ES) group, self-expanding metallic stents (SEMS) group and self-expanding metallic stents plus neoadjuvant chemotherapy (SEMS+NAC) group. Wexner score for incotinence (higher score indicates the worse anal function), Vaizey score (>10 indicates fecal incontinence) and low anterior resection syndrome (LARS) scale (higher score indicates the worse anal function) were applied to evaluate anal function of patients among groups at postoperative 1-, 6- and 12-month. EORTC QLQ-C30 questionnaire was used to assess the quality of life. Risk factors of decreased anal function were identified by logistic regression analysis. Results: A total of 72 patients were enrolled, including 27 (37.5%) patients in ES group, 23 (31.9%) in SEMS group and 22 (30.6%) in SEME+NAC group. The baseline characteristics including age, gender, tumor location, comorbidities, total blood loss, operation time and postoperative complications, were comparable among groups, except that the proportion of laparoscopic surgery was significantly lower in ES group (4/27, 14.9%) than that in SEMS (15/23, 65.2%) and SEMS+NAC group (16/22, 72.7%) with significant difference (P<0.001). The follow-up ended up to October 2020, and the overall follow-up rate was 79.2% (57/72). No significant differences existed in the Wexner score of patients among groups at postoperative 1-, 6- and 12-month (all P>0.05). The Vaizey scores at postoperative 1-month in ES, SEMS and SEMS+NAC group were 7 (0-17), 3 (0-7) and 4 (0-8) respectively with significant difference (H=18.415, P=0.001), and the scores in SEMS and SEMS+NAC groups were significantly lower than that in ES group (both P<0.05), while no significant difference existed between SEMS and SEMS+NAC group (P>0.05). Vaizey scores at postoperative 6- and 12-month among 3 groups were not significantly different (both P>0.05). The LARS scores at postoperative 1-month in ES, SEMS and SEMS+NAC groups were 20 (0-37), 15 (0-24) and 16 (0-28) respectively with significant difference (H=3.660, P=0.036), and the scores in SEMS and SEMS+NAC groups were significantly lower than that in ES group (both P<0.05), while no significant difference existed between SEMS and SEMS+NAC groups (P>0.05). LARS scores at postoperative 6- and 12-month among 3 groups were not significantly different (both P>0.05). The QLQ-C30 score revealed that the social function of patients in SEMS group and SEMS+NAC group was significantly better than that in ES group (both P<0.05), while no significant difference existed between SEMS and SEMS+NAC group (P>0.05). The logistic regression analysis revealed that only ES was an independent risk factor of decreased anal function (OR=2.264, 95% CI: 1.098-4.667, P=0.027). Conclusion: Compared to ES, SEMS may improve quality of life and short-term anal function of patients with complete obstructive left hemicolon cancer.

ABSTRACT

Anastomotic leak is one of the most severe complications following right hemicolectomy but rarely happens, which should be diagnosed based on clinical manifestations, laboratory and radiographic examinations. Influencing factors of anastomotic leak after right hemicolectomy include bowel preparation, emergency surgery, anastomotic procedure (side-to-side anastomosis vs. end-to-side anastomosis, instrument anastomosis vs. manual technigue and intracorporeal vs. extracorporeal anastomosis), surgical resection range and patient's characteristics. The occurrence of anastomotic leak might be avoided by standardized operations and indocyanine green fluorescence imaging. Active treatment is recommended once anastomotic leak is diagnosed. Most patients can be cured by non-surgical treatments such as adequate drainage and anti-infection therapy. When severe sepsis happens or non-surgical treatment fails, surgical treatment should be carried out in time.

ABSTRACT

Objective: To compare the morbidity of perineum-related complication between biological mesh and primary closure in closing pelvic floor defects following extralevator abdominoperineal excision (ELAPE). Methods: A literature search was performed in PubMed, Embase, Cochrane Library, Web of Science, Wanfang database, Chinese National Knowledge Infrastructure, VIP database, and China Biological Medicine database for published clinical researches on perineum-related complications following ELAPE between January 2007 and August 2020. Literature inclusion criteria: (1) study subjects: patients undergoing ELAPE with rectal cancers confirmed by colonoscopy pathological biopsy or surgical pathology; (2) study types: randomized controlled studies or observational studies comparing the postoperative perineum-related complications between the two groups (primary perineal closure and reconstruction with a biological mesh) following ELAPE; (3) intervention measures: biological mesh reconstruction used as the treatment group, and primary closure used as the control group; (4) outcome measures: the included literatures should at least include one of the following postoperative perineal complications: overall perineal wound complications, perineal wound infection, perineal wound dehiscence, perineal hernia, chronic sinus, chronic perineal pain (postoperative 12-month), urinary dysfunction and sexual dysfunction. Literature exclusion criteria: (1) data published repeatedly; (2) study with incomplete or wrong original data and unable to obtain original data. Two reviewers independently performed screening, data extraction and assessment on the quality of included studies. Review Manager 5.3 software was used for meta-analysis. The mobidities of perineum-related complications, including overall perineal wound (infection, dehiscence, hernia, chronic sinus) and perineal chronic pain (postoperative 12-month), were compared between the two pelvic floor reconstruction methods. Finally, publication bias was assessed, and sensitivity analysis was used to evaluate the stability of the results. Results: A total of five studies, including two randomized controlled studies and three observational controlled studies, with 650 patients (399 cases in the biological mesh group and 251 cases in primary closure group) were finally included. Compared with primary closure, biological mesh reconstruction had significantly lower ratio of perineal hernia (RR=0.37, 95%CI: 0.21-0.64, P<0.001). No significant differences in ratios of overall perineal wound complication, perineal wound infection, perineal wound dehiscence, perineal chronic sinus and perineal chronic pain (postoperative 12-month) were found between the two groups (all P>0.05). Conclusion: Compared with primary closure, pelvic floor reconstruction following ELAPE with biological mesh has the advantage of a lower incidence of perineal hernia.

ABSTRACT

OBJECTIVE: To investigate the influential factors of tacrolimus (TAC) blood concentration in patients with nephrotic syndrome (NS) of different nationalities. METHODS: In retrospective study, clinical information of 104 patients who diagnosed as NS and met inclusion/exclusion criteria were collected from the First Affiliated Hospital of Xinjiang Medical University during Dec. 2017 and Nov. 2018, including gender, age, ethnicity, height, body weight, laboratory test items, combined drug use and TAC dosage. Influential factors for TAC blood concentration were analyzed by SPSS 22.0 software, and effects of combined use of Wuzhi capsule on steady-state blood trough concentration ([ss][c min]) and dose of TAC were also analyzed. RESULTS: Among 104 patients, totally TAC blood concentration of 394 case times were monitored; using TAC standardized blood concentration as endpoint, Han nationality group was significantly lower than Uygur and Kazak nationality group (P=0.003); patients receiving combined use of Wuzhi capsule were significantly higher than those without combined use of Wuzhi capsule (P=0.056); the patients with combined use of calcium antagonists was significantly higher than the patients without calcium antagonists (P=0.01); the patients with combined use of proton pump inhibitors were significantly lower than those without combined proton pump inhibitors (P=0.01); patients with normal hematocrit were significantly lower than those with abnormal hematocrit (P=0.001); patients with normal urea nitrogen were significantly lower than those with abnormal urea nitrogen (P<0.001). The dose of TAC in patients receiving combined Wuzhi capsule were significantly lower than those without combined use of Wuzhi capsule (P=0.001), there was no significant difference in [ss][c min] of TAC between them (P=0.29). CONCLUSIONS: For NS patients, the effects of ethnicity, calcium antagonists, proton pump inhibitors, hematocrit, urea nitrogen and Wuzhi capsules on TAC blood concentration should be considered when TAC is used.

ABSTRACT

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.

ABSTRACT

As one of the most common pathogens in aquatic animals, Aeromonas hydrophila exhibits a wide range of pathogenicity. Due to factors like unreasonable use of antibiotics and horizontal gene transfer mediated by plasmids, many resistant strains of Aeromonas hydrophila were isolated from ready-to-eat seafood products in retail markets, supermarkets and restaurants. These strains carry many resistance genes. Therefore, it is essential to explore the key control points, and seek for prevention and control strategies so as to effectively alleviate antibiotic resistance. We review here the prevalence of drug resistance of Aeromonas hydrophila in China, and its main infection and resistance mechanisms, and the main means and strategies for reducing and preventing drug resistance. We also address further research directions and focus on drug resistance in Aeromonas hydrophila of the aquatic product.

ABSTRACT

<p><b>Background</b>The introduction of individualized abdominoperineal excision (APE) may minimize operative trauma and reduce the rate of complications. The purpose of this study was to evaluate the safety and efficacy of individualized APE for low rectal cancer.</p><p><b>Methods</b>Fifty-six patients who underwent individualized APE from June 2011 to June 2015 were evaluated retrospectively in Beijing Chaoyang Hospital, Capital Medical University. The main outcome measures were circumferential resection margin (CRM) involvement, intraoperative perforation, postoperative complications, and local recurrence. Statistical analysis was performed using SPSS version 16.0.</p><p><b>Results</b>Fifty (89%) patients received preoperative chemoradiotherapy: 51 (91%) patients were treated with the sacrococcyx preserved; 27 (48%) patients with the levator ani muscle partially preserved bilaterally; 20 (36%) patients with the levator ani muscle partially preserved unilaterally and the muscle on the opposite side totally preserved; 7 (13%) patients with intact levator ani muscle and part of the ischioanal fat bilaterally dissected; and 2 (4%) patients with part of the ischioanal fat and intact lavator ani muscle dissected unilaterally and the muscle on the opposite side partially preserved. The most common complications included sexual dysfunction (12%), perineal wound complications (13%), urinary retention (7%), and chronic perineal pain (5%). A positive CRM was demonstrated in 3 (5%) patients, and intraoperative perforations occurred in 2 (4%) patients. On multiple logistic regression analysis, longer operative time (P = 0.032) and more intraoperative blood loss (P = 0.006) were significantly associated with perineal procedure-related complications. The local recurrence was 4% at a median follow-up of 53 months (range: 30-74 months).</p><p><b>Conclusion</b>With preoperative chemoradiotherapy, individualized APE may be a relatively safe and feasible approach for low rectal cancer with acceptable oncological outcomes.</p>

ABSTRACT

Objective To evaluate the diagnosis value of the percentage of Tie 2-expressing monocytes(TEMs)in CD14+CD16+monocytes of peripheral blood from hepatocellular carcinoma(HCC) patients with negative AFP and tumor size≤3 cm.Methods Flow Cytometry(FCM)was used to determine the percentage of TEMs in CD14+CD16+monocytes of peripheral blood from patients with HCC(n=82), liver cirrhosis(n=29), chronic hepatitis B(n=28), and healthy controls(n=31).Abbott i2000 microparticle chemiluminescence immunoassay analyzer was used to determine the plasma alpha -fetoprotein (AFP)levels.The difference among multi groups was analyzed by the Kruskal-Wallis H test.Two independent groups were analyzed by the Mann-Whitney U test.The chi-square test was used in the rate comparison.The correlation between TEMs and AFP was analyzed by Spearman rank correlation analysis. Morever, the areas under the receiver operating characteristic curves(ROC-AUC), sensitivity and specificity of TEMs or AFP in differentiating HCC, HCC with AFP negative or tumor size≤3 cm were analyzed.Results The percentage of TEMs in CD14 +CD16 +monocytes of peripheral blood from HCC or HCC with negative AFP or HCC with tumor size≤3 cm was significantly higher than that in patients with liver cirrhosis,chronic hepatitis B and healthy controls(P<0.05).ROC-AUC of TEMs and AFP in the diagnosis of HCC were 0.701(95% CI 0.626-0.768)and 0.712(95% CI 0.638-0.779) respectively.When the cut-off values of TEMs and AFP were 4.95%and 20 μg/L,the sensitivities of TEMs and AFP were 71.95%and 45.12%,and the specificities of TEMs and AFP were 70.45%and 85.23%. The sensitivity of TEMs in the diagnosis of HCC was significantly higher than that of AFP(χ2=12.16,P=0.000).The specificity of AFP was significantly higher than that of TEMs(χ2=5.57,P=0.018).There was a highest sensitivity(89.02%)in TEMs/AFP method,and there was a highest specificity(93.18%) in TEMs+AFP method in the diagnosis of HCC.There was no significant difference between the ROC-AUC for the TEMs and the AFP in the diagnosis of 26 patients with tumor size≤3 cm HCC(0.776 vs 0.645,Z=1.805,P=0.071),TEMs/AFP had the highest sensitivity(84.62%),while TEMs+AFP had the highest specificity(93.18%)in the diagnosis of tumor size≤3cm HCC.The ROC-AUC for the TEMs in the diagnosis of 45 patients with AFP negative HCC was 0.739(95%CI 0.648-0.829).The sensitivity and specificity of TEMs were 80.0% and 70.45% respectively.There was no correlation between the level of plasma AFP and the percentage of TEMs(r=-0.169, P=0.129)determined by Spearmans rank correlation coefficient.Conclusions TEMs is valuable in the diagnosis of HCC with negative AFP and tumor size≤3cm,and the two tests of TEMs and AFP can complement each other in the diagnosis of patients with HCC.
