Abstract
OBJECTIVE The aim of this study was to explore the regulatory role of TRIM66 in the development of hepatocellular carcinoma (HCC), and to investigate its underlying mechanism. PATIENTS AND METHODS A total of 88 pairs of HCC tissues and para-cancerous tissues were surgically resected. The expression of TRIM66 was detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The correlation between TRIM66 expression and clinic-pathologic characteristics of HCC patients was analyzed. Follow-up data of enrolled HCC patients were collected for survival analysis. Subsequently, TRIM66 expression in HCC cells was determined by qRT-PCR as well. By constructing si-TRIM66, the biological performances of transfected HCC cells were determined using cell counting kit-8 (CCK-8), colony formation and transwell assay. Western blot was performed to measure the protein expressions of relative genes in epithelial-mesenchymal transition (EMT) pathway. Finally, HCC cells were co-transfected with si-TRIM66 and pcDNA-E-cadherin, followed by detection of invasive and migratory abilities. RESULTS TRIM66 was highly expressed in HCC tissues compared with that of para-cancerous tissues. High expression of TRIM66 was positively correlated with tumor stage, lymph node metastasis and distant metastasis, whereas not correlated with age and sex of HCC patients. Kaplan-Meier curves revealed that a higher expression of TRIM66 was associated with worse prognosis of HCC. Similarly, TRIM66 was also highly expressed in HCC cells. The knockdown of TRIM66 in HCC cells significantly inhibited the proliferative, invasive and migratory abilities of transfected cells. However, TRIM66 down-regulation significantly induced cell apoptosis. Western blot results showed that TRIM66 knockdown in HCC cells markedly downregulated the protein expressions of E-cadherin, N-cadherin, Vimentin and β-catenin. The inhibited migration and invasion of HCC cells resulted from TRIM66 knockdown were partially reversed by E-cadherin overexpression. CONCLUSIONS TRIM66 is highly expressed in HCC, which is positively correlated with tumor stage, lymph node metastasis and distant metastasis of HCC patients. In addition, TRIM66 promotes the malignant progression of HCC by inhibiting E-cadherin through the EMT pathway.

Abstract
Objective: To explore the influence of inhalation injury on fluid resuscitation of massive burn patients during shock stage. Methods: A total of 74 massive burn patients (65 males and 9 females, aged 21 to 65 years) admitted to the Second Affiliated Hospital of Air Force Medical University (n=57) and Yan'an University Affiliated Hospital (n=17) from May 2009 to December 2019 were enrolled in this retrospective cohort study. Patients were divided into inhalation injury group (n=56) and non-inhalation injury group (n=18) based on clinical symptoms, vital signs, and results of bronchofibroscopy. Then 26 patients in inhalation injury group and 13 patients in non-inhalation injury group were 1∶2 matched by case-control matching based on the difference of total burn surface area. The total fluid replacement coefficient, crystalloid replacement coefficient, colloid replacement coefficient, glucose input volume, ratio of crystalloid to colloid, urine volume, and cumulative ratio of input to output volume during the first 24 h post injury, the second 24 h post injury, and the third 24 h post injury, heart rate, respiratory rate, mean arterial pressure (MAP), and hematocrit (HCT) at post injury hour (PIH) 24, 48, and 72 were recorded and compared between the two groups. Data were statistically analyzed with analysis of variance for repeated measurement and Bonferroni correction, t test, Fisher's exact probability test, and Mann-Whitney U test. Results: (1) After matching, during the first to third 24 h post injury, the total fluid replacement coefficient and glucose input volume of patients in inhalation injury group were significantly higher than those in non-inhalation injury group (F=4.202, 10.671, P<0.05 or P<0.01). During the first, second, and third 24 h post injury, the total fluid replacement coefficient, crystalloid replacement coefficient, colloid replacement coefficient, and ratio of crystalloid to colloid were similar between the patients in two groups(t=-1.336, -1.452, -1.998; -0.148, 0.141, 0.561; 0.916, -0.046, -0.509; -1.024, 0.208, 0.081, P>0.05). During the first, second, and third 24 h post injury, the glucose input volume of patients in inhalation injury group were respectively (2 996±1 176), (2 659±1 030), and (2 680±1 509) mL, which were significantly higher than (2 125±898), (1 790±828), and (1 632±932) mL in non-inhalation injury group (t=-2.334, -2.639, -2.297, P<0.05). (2) After matching, in overall comparison between groups, during the first to third 24 h post injury, the urinary output volumes and cumulative ratios of input to output volume of patients in inhalation injury group were significantly lower or higher than those in non-inhalation injury group, respectively (F=12.158, 9.111, P<0.01). At PIH 24, 48, and 72, heart rate of patients in inhalation injury group were significantly higher than those in non-inhalation injury group (F=4.675, P<0.05). There were no statistically significant differences in heart rate, respiratory rate, MAP, and HCT between patients in the two groups at PIH 24 and 48 (t=-0.039, -1.688, 1.399, 1.299, -1.741, 0.754, -0.677, 0.037, P>0.05). During the first and second 24 h post injury, the urine volume and cumulative ratio of input to output volume of patients in inhalation injury group were respectively significantly lower and higher than those in non-inhalation injury group (t(urine volume)=2.421, 2.876, t(cumulative ratio of input to output volume)=-2.687、-2.943, P<0.05 or P<0.01). At PIH 72, the heart rate and HCT of patients in inhalation injury group ( (114±13) times/min, 0.42±0.06) were significantly higher than those in non-inhalation injury group ( (98±18) times/min, 0.38±0.06, t=-3.182, -2.123, P<0.05 or P<0.01), there were no statistically significant differences in respiratory rate and MAP between the patients in two groups (t=0.359, 1.722, P>0.05). During the third 24 h post injury, there were no statistically significant differences in urine volume and cumulative ratio of input to output volume between the patients in two groups (t=1.664, -1.895, P>0.05). Conclusions: The presence of inhalation injury can lead to increased fluid requirement in massive burn patients during shock stage. An appropriate increase of fluid volume in the fluid resuscitation of burn patients combined with inhalation injury would be beneficial for maintaining ideal urine output.

Abstract
Sea cucumber is a sensitive organism that is easily challenged by environmental change. The aim of this study was to characterize the proteome of sea cucumbers from 5 main Chinese origins, including Xiamen (XM), Dalian (DL), Weihai (WH), Yantai (YT) and Qingdao (QD). In this work, a tandem mass tag (TMT) labeling proteomic approach was applied to identify and quantify the proteome of sea cucumber. A total of 5051 proteins were identified in the body wall; among those proteins, 1594 proteins (31.6%) were identified as enzyme proteins, and 33 proteins belonged to collagen. In addition, the 10 most highly abundant proteins were further discussed. Among all quantified proteins, 2266 were significantly differentially expressed proteins (SDEPs) across the 5 origins. These SDEPs were related to pigmentation (5 proteins), antioxidant activity (13 proteins), and immune system processes (29 proteins). Based on SDEPs, DL differed the most from QD and XM, as well as WH and YT, as shown in principal component analysis (PCA) and hierarchical clustering. In conclusion, one-fourth of the significantly different proteins found in the sea cucumber body wall among the 5 main Chinese locations indicated the sensitivity of sea cucumber to variations in temperature, environment, and feeding.

Abstract
OBJECTIVE To detect the chloroquine-resistant molecular marker polymorphisms in Plasmodium falciparum imported into China, investigate the mutation types of P. falciparum chloroquine resistant transporter (Pfcrt) gene at positions 72 to 76, and analyze the specificity of the P. falciparum specimens with different origins. METHODS A total of 674 filter paper blood samples were collected from the National Malaria Diagnosis Reference Laboratory of China in 2012 and 2018. The amino acid po- sitions 72 to 76 of the Pfcrt gene on chromosome 7 were amplified using nested PCR assay and sequenced, and the sequencing results of the target gene fragment and the geographical region-specific prevalence of the mutations in the Pfcrt gene were analyzed. RESULTS Among the 674 imported P. falciparum malaria cases in China in 2012 and 2018, 99.5% (644/674) were from Africa, which were predominantly from western and central Africa (80.4%, 518/644), and 4.5% (30/674) from Southeast Asia and Oceania (Papua New Guinea). A total of 4 site mutations (C72S, M74I, N75E and K76T) and 5 haplotypes (CVMNK, CVIET and SVMNT and two mixed types) were identified, with haplotypes CVMNK and CVIET present in parasites of both African and Southeast Asian origins, SVMNT detected in Southeast Asia (Myanmar) and Papua New Guinea isolates, the mixed type of haplo- types CVMNK/CVIET detected in P. falciparum of African and Southeast Asian origins, and the mixed type of haplotypes CVMNK/SVMNT detected only in the Myanmar isolate. Most P. falciparum parasites of the African origin carried the wild-type Pfcrt allele (77.7%, 478/615), and 68.0% (17/25) of the P. falciparum parasites of the Southeast Asian and Papua New Guinea or- igins harbored chloroquine resistant molecular markers (χ2 = 28.5, P < 0.05). The constituent ratio of the wild- and mutant-type Pfcrt allele varied in different geographical regions of Africa (P < 0.01), and the lowest prevalence of the wild-type Pfcrt allele was seen in western Africa. CONCLUSIONS Among the 674 imported malaria cases in China in 2012 and 2018, the P. falciparum imported from Sotheast Asia habors a higher proportion of resistance to chloroquine and a higher molecular polymophism at ami- no acid positions 72 to 76 of the Pfcrt gene than the parasite of the African origin.

Abstract
Background:Donor-specific anti-HLA antibodies (DSAs) are antibodies in the recipient directed against donor class I/II HLA antigens. The existence of DSAs before allogenic hematopoietic stem cell transplantation (AHSCT) are known to cause primary graft failure. Currently there’s no established method of DSA desensitization due to the long half-life of plasma cells.Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disease involving in multiple organ systems mediated by numerous autoantibodies. Recent results have shown that depletion of B cells by CD19 CAR-T cells effectively reversed some manifestations in two SLE mouse models. However, plasma cells could be spared with single CD19 CAR-T cells, and peripheral circulating anti-DNA IgG and IgM autoantibodies remain elevated or increased in treated mice.Objectives:We present the efficacy of BCMA-CD19 compound CAR (cCAR), which target on antibody- producing “root”, both B cells and plasma cells in preclinical study and in our first-in-human phase 1 clinical trial.Methods:We constructed a BCMA-CD19 cCAR composed of a complete BCMA-CAR fused to a complete CD19 CAR, separated by a self-cleaving P2A peptide. We assessed the functional activity of cCAR in co-culture assay with multiple cell lines. We also verified cCAR efficacy with two mouse models, injected with either BCMA-expressing MM.1S cells or CD19-expressing REH cells. In our phase 1 clinical trial, we enrolled patients with hematologic malignancies with antibody mediated disorders.Results:BCMA-CD19 cCAR exhibited robust cytotoxic activity against the K562 cells engineered to express either CD19 or BCMA in co-culture assays, indicating the ability of each complete CAR domain to specifically lyse target cells. In mouse model study, cCAR-T cells were able to eliminate tumor cells in mice injected with MM.1S cells and REH cells, indicating that both BCMA and CD19 are specifically and equally lysing B cells and plasma cells in vivo, making BCMA-CD19 cCAR a candidate for clinical use.In our first-in-human clinical trial, the first case is a 48-year-old female patient having resistant B-ALL with high DSA titers. She exhibited complete remission of B-ALL at day 14 post-CAR T treatment. MFI of DSA dropped from 7800 to 1400 at 8 weeks post cCAR treatment, the reduction percentage was approximately 80% (Figure 1). The patient had no CRS, and no neurotoxicity was observed.Figure 1.1. A) MFI of DSA and other HLA antibodies before and at different time points after cCAR T infusion. B) the percent reduction post-transfusion of cCAR T cells at different time points.The second case is a 41-year-old female patient having a refractory diffuse large B cell lymphoma with bone marrow (BM) involvement. Furthermore, she has a 20 years of SLE, with manifestation of fever dependent of corticosteroids. On day 28 after cCAR treatment, PET/CT scan showed CR, and BM turned negative. In addition, she is independent of steroids, has no fever and other manifestations, C3/C4 are within normal ranges, and all the ANA dropped significantly, especially the nuclear type ANA, which turned from> 1:1000 to be negative at day 64. She had Grade 1 CRS but with no neurotoxicity observed. The absence of B cells and plasma cells persisted more than 5 months post CAR therapy.Conclusion:Our first in human clinical trial on BCMA-CD19 cCAR demonstrated profound efficacy in reducing DSA levels in an AHSCT candidate and ANA titer in a SLE patient. There was strong clinical evidence of depletion of antibody-producing roots, B-cells and plasma cells in both patients. Our results further suggested that BCMA-CD19 cCAR has the potential to benefit patients receiving solid organ transplants or those with other antibody-mediated diseases.Figure 2.Reduction of different type of ANA titer at different time points.Acknowledgments:patients and their familiesDisclosure of Interests:Fang liu: None declared, Hongyu Zhang: None declared, Xiao Wang: None declared, Jia Feng: None declared, Yuanzhen cao Employee of: Employee of iCell Gene Therapeutics LLC, Yi Su: None declared, Masayuki Wada Employee of: employee of iCell Gene Therapeutics LLC, Yu Ma Employee of: employee of iCAR Bio Therapeutics Ltd, Yupo Ma Shareholder of: shareholder of iCell Gene Therapeutics LLC

Abstract
We report the observation of new properties of primary cosmic rays, neon (Ne), magnesium (Mg), and silicon (Si), measured in the rigidity range 2.15 GV to 3.0 TV with 1.8×10^{6} Ne, 2.2×10^{6} Mg, and 1.6×10^{6} Si nuclei collected by the Alpha Magnetic Spectrometer experiment on the International Space Station. The Ne and Mg spectra have identical rigidity dependence above 3.65 GV. The three spectra have identical rigidity dependence above 86.5 GV, deviate from a single power law above 200 GV, and harden in an identical way. Unexpectedly, above 86.5 GV the rigidity dependence of primary cosmic rays Ne, Mg, and Si spectra is different from the rigidity dependence of primary cosmic rays He, C, and O. This shows that the Ne, Mg, and Si and He, C, and O are two different classes of primary cosmic rays.

Abstract
BACKGROUND Various minimally invasive approaches have been described for infected necrotizing pancreatitis. This article describes a modified minimal-access retroperitoneal pancreatic necrosectomy (MARPN) procedure assisted by gas insufflation. METHODS This retrospective, observational study documented patients who had undergone a step-up MARPN between 1 January 2010 and 31 December 2016. A minimum follow-up of 1 year was required for inclusion. The step-up approach involved percutaneous catheter drainage followed by the modified MARPN and necrosectomy. If more than one access site was needed it was categorized as complex MARPN. RESULTS Of 212 patients with infected necrotizing pancreatitis, 164 (77·4 per cent) underwent a step-up approach. The median number of percutaneous catheter drains and MARPN procedures was 3 (range 1-7) and 1 (1-6) respectively. Ninety patients (54·9 per cent) underwent complex MARPN. For residual necrosis after MARPN, three patients (1·8 per cent) underwent sinus tract gastroscopy, and 11 (6·7 per cent) had sinography combined with a tube change. However, operations in 13 patients (7·9 per cent) required conversion to open surgery. Postoperative complications developed in 103 patients (62·8 per cent). The mortality rate was 6·1 per cent (10 deaths). CONCLUSION A step-up approach using a modified MARPN for infected necrotizing pancreatitis is a reasonable option.

Abstract
The explicit breaking of the axial symmetry by quantum fluctuations gives rise to the so-called axial anomaly. This phenomenon is solely responsible for the decay of the neutral pion π0 into two photons (γγ), leading to its unusually short lifetime. We precisely measured the decay width Γ of the [Formula: see text] process. The differential cross sections for π0 photoproduction at forward angles were measured on two targets, carbon-12 and silicon-28, yielding [Formula: see text], where stat. denotes the statistical uncertainty and syst. the systematic uncertainty. We combined the results of this and an earlier experiment to generate a weighted average of [Formula: see text] Our final result has a total uncertainty of 1.50% and confirms the prediction based on the chiral anomaly in quantum chromodynamics.

Abstract
An inelastic excitation and cluster-decay experiment ^{2}H(^{16}C,^{4}He+^{12}Be or ^{6}He+^{10}Be)^{2}H was carried out to investigate the linear-chain clustering structure in neutron-rich ^{16}C. For the first time, decay paths from the ^{16}C resonances to various states of the final nuclei were determined, thanks to the well-resolved Q-value spectra obtained from the threefold coincident measurement. The close-threshold resonance at 16.5 MeV is assigned as the J^{π}=0^{+} band head of the predicted positive-parity linear-chain molecular band with (3/2_{π}^{-})^{2}(1/2_{σ}^{-})^{2} configuration, according to the associated angular correlation and decay analysis. Other members of this band were found at 17.3, 19.4, and 21.6 MeV based on their selective decay properties, being consistent with the theoretical predictions. Another intriguing high-lying state was observed at 27.2 MeV which decays almost exclusively to ^{6}He+^{10}Be(∼6 MeV) final channel, corresponding well to another predicted linear-chain structure with the pure σ-bond configuration.

Abstract
Passive interception of fog from the wind is an effective solution for accessing water in regions where fog is frequent and other sources scarce. A Namib Desert beetle is often cited as bioinspiration for further advancement, in a narrative which focuses on patterned wettability of its bumpy elytra as a means of transporting accumulated water from its back to its mouth. However, surface transport in fog collection is secondary to the role of the fluid dynamics of droplet deposition, in which inertial droplets migrate across diverging streamlines approaching an obstruction. 3D geometry of biological surface features inevitably affect this process, but its specific role in flow physics of fog collection has not previously been explored. Here, we report experimental measurements of deposition efficiency of targets with identical surface chemistry but varying surface morphology. We find a nearly threefold increase in collection upon addition of millimetric bumps to a spherical target, and provide insight into the micromechanics underlying the performance. Modifying surface morphology can be easier than overall geometry for both manufactured structures and evolved organisms and should therefore be both considered in the design of separation devices and expected in other biological systems for which extraction of particles from flow is important.

Abstract
OBJECTIVE: To evaluate the accuracy of molecular diagnostics for the detection of drug-resistant tuberculosis (TB) in Chinese patients.METHOD: Seven databases were searched for eligible studies that evaluated the accuracy of molecular diagnostics against drug susceptibility testing (DST) for detecting drug resistance. A bivariate random-effects meta-analysis was conducted to pool sensitivity and specificity by the index test and drug resistance type.RESULTS: A total of 159 studies were included. Compared with DST (reference standard), Xpert® could diagnose rifampicin (RMP) resistant TB accurately, with a pooled sensitivity and pooled specificity of 92% (95%CI 90-94) and 98% (95%CI 97-98), respectively. Line-probe assays (LPAs) also performed well for RMP resistance, with a pooled sensitivity of 91% (95%CI 88-93) and pooled specificity of 98% (95%CI 96-99), but not for isoniazid (INH) or second-line drugs due to lower sensitivity (<80%). The pooled sensitivity of GeneChip® microarrays for RMP, INH and multidrug resistance was 89% (95%CI 86-91), 79% (95%CI 75-82) and 79% (95%CI 73-84), respectively, and the specificities were all >97%. Similarly, the MeltPro® TB/STR assay had better sensitivity and specificity for first-line drugs, varying from 87% to 89% and 97% to 98%, respectively, than for second-line drugs.CONCLUSION: The Xpert assay, LPA, GeneChip assay, and MeltPro assay are credible methods with high accuracy for RMP resistance detection, but they may not be appropriate for other anti-tuberculosis drugs due to low sensitivity.

Abstract
A total of 129 wheat cultivars collected from local breeders in four ecological regions in China was evaluated for Fusarium head blight resistance after natural infection under epidemic conditions. The disease index was scored and seven toxins concentrations were determined by UPLC-MS/MS. The disease index ranged from 6.3 to 80.9% and a strong correlation was found between the regions from which the cultivars originate and disease index. The middle and lower reaches of Yangtze River Region showed the highest disease resistance, followed by the upper reaches of the Yangtze River Region. FHB resistance of cultivars from northern and southern Huanghuai Region was lowest and all cultivars in these regions are highly or moderately susceptible. Disease index was significantly correlated with toxin accumulation on nation scale, but no clear correlation was found within most ecological regions. The toxin accumulation was also not well correlated with resistant levels. As the incidence of FHB has increased dramatically over the last decade, improved FHB resistance in cultivars is urgently needed. We recommend that besides scoring for disease index also mycotoxin accumulation in cultivars is incorporated in breeding procedures and the evaluation of cultivars.

Abstract
AIMS To extract and identify the metabolites of strain A217 as well as its antifungal spectrum and control effect on various plant pathogens. METHODS AND RESULTS Strain A217 was identified as a Streptomyces sp. which was most similar to Streptomyces lienomycini. An antimicrobial spectrum test indicated that strain A217 inhibited several plant pathogenic fungi and strong antibacterial effect such as Phytophthora capsici, Botrytis cinerea, Sclerotinia sclerotiorum, Fusarium oxysporum, Pseudomonas syringae and Xanthomonas campestris. An in vivo tissue test demonstrated that the fermentation broth of strain A217 exerted therapeutic and protective effects of 49·47 and 61·60% respectively, on S. sclerotiorum. Additionally, the fermentation broth of A217 exerted control effects on walnut black spot disease in walnut leaves and branches amounting to 79·33 and 81·52% respectively. In a pot experiment, the fermentation broth exhibited a stronger protective and control effect (68·29%), as well as better bacteriostatic and disease control effects on Phytophthora blight of pepper, compared with Metalaxyl. Compounds possessing antifungal and antibacterial activities were obtained from the fermentation broth of strain A217, using column chromatography and HPLC. Chemical and structural analyses conducted using MS and nuclear magnetic resonance confirmed that these compounds were 1H-pyrrole-2-carboxylic acid and 1H-pyrrole-2-carboxamide. The EC50 values of compound 1H-pyrrole-2-carboxylic acid1 for S. sclerotiorum and P. capsici were 20·13 and 50·36 μg ml-1 respectively. Compound 1H-pyrrole-2-carboxamide2 showed significant antibacterial activity against different plant pathogenic bacteria. The MIC values of P. syringae, X. campestris and X. campestris pv. jugiandis were 7·5, 30 and 15·0 μg ml-1 respectively. CONCLUSIONS Actinomyces A217 fermentation products have a broad spectrum of bacteriostasis, and have good bacteriostasis activity to many plant pathogenic fungi and bacteria. SIGNIFICANCE AND IMPACT OF THE STUDY The present study revealed a new antimicrobial producing strain of Streptomyces and its potential application as a biological control agent for plant diseases.

Abstract
Objective: To investigate the value of rapid on-site evaluation (ROSE) of bronchoscopy in the diagnosis of pulmonary complications after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: A retrospective analysis was conducted on the diagnosis and treatment process before and after ROSE examination of 12 patients with pulmonary complications after allo-HSCT who were admitted to the Department of hematology, Tianjin First Central Hospital from January 2017 to June 2019. The diagnostic accuracy of the ROSE was evaluated by comparing the initial diagnosis of ROSE with the final clinical diagnosis. At the same time, the safety of ROSE examination was evaluated and two typical cases were shared. Results: In the 12 transbronchial lung biopsies, there were 5 cases of organizing pneumonia, 3 cases of bronchiolitis obliterans with organizing pneumonia, 1 case of pulmonary fibrosis, 1 case of acute fibrinous and organizing pneumonia, 1 case of pseudomembranous tracheobronchial aspergillosis and 1 case of uncertain diagnosis evaluated by ROSE. Compared with the final clinical diagnosis, there were 10 cases of accurate diagnosis made by ROSE (10/12). All patients were well tolerant to the operation of bronchoscopy. There was only a small amount of bleeding observed during the operation, without pneumothorax and hemoptysis. And no complications related to ROSE occurred. According to the initial diagnosis of ROSE, 10 cases of non-infectious pulmonary complications were treated with methylprednisolone or other immunosuppressive agents and 1 case of Aspergillus infection was given antifungal therapy. Seven patients with non-infectious pulmonary complications improved after treatment. One patient obtained uncertain diagnosis by ROSE was later diagnosed with virus infection by next generation sequencing technology and improved after treatment with foscarnet sodium and immunoglobulin. As of June 30, 2019, 7 patients improved and 5 died. Conclusion: ROSE has the advantages of diagnostic accuracy and rapidity, and is very suitable for patients with critical illness after hematopoietic stem cell transplantation, who are in urgent need of definite diagnosis and prompt treatment, which is beneficial to improve the prognosis of patients.

Abstract
Objective: To examine the effectiveness of non-operative of colonic fistula following acute pancreatitis. Methods: Retrospective analysis of 354 patients with acute pancreatitis who were admitted to Department of Hepatobiliary Surgery of Chinese People's Liberation Army General Hospital from January 2013 to December 2018. Age of the patients was (46±14) years (range: 14-85 years); 249 cases (70.3%) were males. There were 41 cases of acute edematous pancreatitis and 313 cases of acute necrotising pancreatitis. Two hundred and fifteen cases were diagnosed as moderate severe acute pancreatitis and 139 were diagnosed as severe acute pancreatitis. Among 313 cases of acute necrotising pancreatitis, 62 cases underwent non-surgical treatment, 251 cases underwent surgical treatment in which 218 of minimal access retroperitoneal pancreatic necrosectomy underwent percutaneous nephroliguectomy with peripancreatic necrotic tissue removal technique. Results: There were 15 cases of colon fistula following acute necrotising pancreatitis, and the incidence rate was 4.2%(15/354). There were 7 males and 8 females, with age of (39±8) years (range: 27 to 50 years). The median interval between acute pancreatitis onset and diagnosis of colonic fistula was 71 days(27-134) days. Two cases occurred at the hepatic flexure of the colon, 4 cases at transverse colon, and 9 cases at splenic flexure of colon. Of the 354 patients, 39 cases died and the mortality was 11.0%. Two patients underwent laparotomy, and one of them died. The remaining 13 patients underwent non-surgical treatment and were discharged. Conclusion: Acute pancreatitis with colonic fistula can be treated with non-surgical treatment and can achieve good prognosis.
