RESUMEN
Objective:To compare the safety and efficacy of the " step-up approach" versus the " step-jump approach" in treatment of infected pancreatic necrosis (IPN).Method:The clinical data of IPN patients who underwent step-up strategy or step-jump strategy treatment at the Department of Pancreatic and Biliary Surgery of the First Affiliated Hospital of Harbin Medical University from December 2018 to November 2022 were analyzed retrospectively. Propensity score matching (PSM) was done based on the nearest neighbor matching method (1: 1 ratio). After matching the baseline data (the caliper value was 0.01), a total of 62 patients with IPN were included, including 41 males and 21 females, aged (41.1±13.1) years old. Patients who were treated with the step-up strategy were included in the step-up group, while patients who were treated with the step-jump strategy were included in the step-jump group. There were 31 patients in each group after PSM, and the treatment effect of the two groups were compared.Results:Of the 62 patients with IPN, 43 received surgical intervention, and 19 were managed successfully using symptomatic anti-inflammatory treatment or percutaneous catheter drainage. The total hospitalization cost of patients in the step-jump group was significantly higher than that in the step-up group [122 000 (73 000, 179 000) yuan vs. 88 000 (46 000, 144 000) yuan, P=0.034]. The overall cure rate of IPN patients in the step-jump group was 93.5%(29/31). The 2 patients who died had type Ⅲ IPN. In the IPN patients in the step-up group were all cured, and the overall cure rate was 100%(31/31), with no death. There were no statistical differences between the two groups in the rates of death, postoperative complications, residual infection, debridement ≥2 times, and positive bacterial culture in blood or drainage fluid (all P>0.05). A total of 19.4% (12/62) patients had postoperative complications, including 4 patients with abdominal bleeding, 3 patients with new organ dysfunction, 2 patients with gastrointestinal bleeding, 2 patients with gastrointestinal fistula, and 1 patient with venous thrombosis in both lower limbs. Conclusion:Both the step-up treatment strategy and the step-jump treatment strategy were safe and effective for treatment of IPN patients.
RESUMEN
In recent years, the risk of perioperative concurrent venous thromboembolism (venous thromboembolism, VTE) has been significantly increased in patients with pancreatic cancer. Early prediction of VTE and strengthening the quality evaluation and clinical management of pancreatic surgery are the key to promote the prevention and treatment of VTE in pancreatic cancer patients. In view of the particularity of pancreatic surgery and the risk of related complications, clinicians should not only focus on the prevention of VTE, but also take into account the occurrence of serious complications such as postoperative bleeding, and strive to balance the two. Based on the relevant guidelines and the clinical experience of the center, the author's team elaborated on the early prediction of VTE in patients with pancreatic cancer, the indication and timing of perioperative VTE prevention and treatment in pancreatic surgery, in order to provide beneficial reference for the clinicians of VTE prevention and treatment in such patients.
RESUMEN
The step-up approach is the most important modality in the treatment of infected pancreatic necrosis (IPN) and has been recommended by several national and international guidelines. Screening patients with low success rates of percutaneous drainage for timely treatment using the step-up approach and selecting appropriate escalation approach based on IPN staging are expected to improve the overall cure rate of IPN. The open debridement in the step-up approach should be carried out under reasonable indications and timing. When the patient's overall condition is poor and the condition of disease is complex, it is not necessary to adhere to a fixed treatment mode and choose a leapfrogging treatment strategy in a timely manner after thorough evaluation.When following the step-up approach in the treatment of IPN, endoscopic and surgical interventions are advocated in parallel, and escalating and leapfrogging strategies are promoted to establish an integrated, disease-centric, multidisciplinary treatment platform, with the aim of improving clinical prognosis. The authors review relevant literature and combine with team's treatment experience to explore the escalating strategies of surgical intervention for IPN, with a view to further improving the overall cure rate of IPN patients.
RESUMEN
Acute pancreatitis is one of the common surgical acute abdominal diseases. Since people first recognized acute pancreatitis in the middle of the nineteenth century, a diversified minimally invasive treatment model with standardization has been formed today. According to the main line of surgical intervention of acute pancreatitis treatment,this period can be roughly divided into five stages:exploration stage, conservative treatment stage, pancreatectomy stage, debridement and drainage of the pancreatic necrotic tissue stage, and minimally invasive treatment as the first choice led by the multidisciplinary team mode stage. Throughout history, the evolution and progress of surgical intervention strategies for acute pancreatitis cannot be separated from the progress of science and technology, the update of treatment concepts and the further understanding of the pathogenesis. This article will summarize the surgical characteristics of acute pancreatitis treatment at each stage to explain the development of surgical treatment of acute pancreatitis,to help investigate the development of surgical treatment of acute pancreatitis in the future.

Objective: To explore the clinical characteristics of various types of infected pancreatic necrosis(IPN) and the prognosis of different treatment methods in the imaging classification of IPN proposed. Methods: The clinical data of 126 patients with IPN admitted to the Department of Pancreatic and Biliary Surgery, the First Affiliated Hospital of Harbin Medical University from December 2018 to December 2021 were analyzed retrospectively. There were 70 males(55.6%) and 56 females(44.4%), with age(M(IQR)) of 44(17)years (range: 12 to 87 years). There were 67 cases(53.2%) of severe acute pancreatitis and 59 cases (46.8%) of moderately severe acute pancreatitis. All cases were based on the diagnostic criteria of IPN. All cases were divided into Type Ⅰ(central IPN)(n=21), Type Ⅱ(peripheral IPN)(n=23), Type Ⅲ(mixed IPN)(n=74) and Type Ⅳ(isolated IPN)(n=8) according to the different sites of infection and necrosis on CT.According to different treatment strategies,they were divided into Step-up group(n=109) and Step-jump group(n=17). The clinical indicators and prognosis of each group were observed and analyzed by ANOVA,t-test,χ2 test or Fisher exact test,respectively. Results: There was no significant difference in mortality, complication rate and complication grade in each type of IPN(all P>0.05). Compared with other types of patients, the length of stay (69(40)days vs. 19(19)days) and hospitalization expenses(323 000(419 000)yuan vs. 60 000(78 000)yuan) were significantly increased in Type Ⅳ IPN(Z=-4.041, -3.972; both P<0.01). The incidence of postoperative residual infection of Type Ⅳ IPN was significantly higher than that of other types (χ2=16.350,P<0.01). There was no significant difference in the mortality of patients with different types of IPN between different treatment groups. The length of stay and hospitalization expenses of patients in the Step-up group were significantly less than those in the Step-jump group(19(20)days vs. 33(35)days, Z=-2.052, P=0.040;59 000(80 000)yuan vs. 122 000(109 000)yuan,Z=-2.317,P=0.020). Among the patients in Type Ⅳ IPN, the hospitalization expenses of Step-up group was significantly higher than that of Step-jump group(330 000(578 000)yuan vs. 141 000 yuan,Z=-2.000,P=0.046). The incidence of postoperative residual infection of Step-up group(17.4%(19/109)) was significantly lower than that of Step-jump group(10/17)(χ2=11.980, P=0.001). Conclusions: Type Ⅳ IPN is more serious than the other three types. It causes longer length of stay and more hospitalization expenses. The step-up approach is safe and effective in the treatment of IPN. However, for infected lesions which are deep in place,difficult to reach by conventional drainage methods, or mainly exhibit "dry necrosis", choosing the step-jump approach is a more positive choice.

In the past decade, the technology of minimally invasive pancreatic surgery (MIPS) has developed rapidly, and now has become an important part of pancreatic surgery. In the context of the minimally invasive era, how to guide surgeons to operate in a standardized manner and mini-mize the surgical risks has become an urgent difficulty to be overcome. Following the 2019 Miami consensus, a more authoritative European guideline for MIPS, The Brescia Internationally Validated European Guidelines on Minimally Invasive Pancreatic Surgery, has emerged. The Brescia Guideline mainly includes eight fields, such as professional terminology formulation, surgical indication evalua-tion, selection of high-risk patients, and key points of intraoperative operation. Combined with the latest literature, the Brescia Guideline puts forward authoritative recommendations in various fields and reflects the status quo and research progress of MIPS.
RESUMEN
Pancreatic surgery is an important specialty in the field of general surgery. As the anatomical location of pancreas is deeply and complex, and the diseases of pancreatic surgery is various kinds of and serious with high difficulty in surgery, the development of pancreatic surgery is slowly in the past. In the recent 20 years, with the deepening of basic and clinical researches in related fields, researchers' cognition of pancreatic diseases has gradually deepened. A series of new con-cepts and techniques have been applied to pancreatic surgery, making pancreatic surgery enter a rapid development stage. At the same time, researchers also recognize that the existing medical concepts and technical means are not sufficient to solve all clinical problems. Therefore, the cancer of pancreatic surgery in China can be alive and flourishing by grasping the opportunities, making continuous exploration and innovation.
RESUMEN
Objective:To investigate the epidemiological characteristics, diagnosis, treat-ment and prognosis of gallbladder cancer in China from 2010 to 2017.Methods:The single disease retrospective registration cohort study was conducted. Based on the concept of the real world study, the clinicopathological data, from multicenter retrospective clinical data database of gallbladder cancer of Chinese Research Group of Gallbladder Cancer (CRGGC), of 6 159 patients with gallbladder cancer who were admitted to 42 hospitals from January 2010 to December 2017 were collected. Observation indicators: (1) case resources; (2) age and sex distribution; (3) diagnosis; (4) surgical treatment and prognosis; (5) multimodality therapy and prognosis. The follow-up data of the 42 hospitals were collected and analyzed by the CRGGC. The main outcome indicator was the overall survival time from date of operation for surgical patients or date of diagnosis for non-surgical patients to the end of outcome event or the last follow-up. Measurement data with normal distribu-tion were represented as Mean±SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and com-parison between groups was conducted using the U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Univariate analysis was performed using the Logistic forced regression model, and variables with P<0.1 in the univariate analysis were included for multivariate analysis. Multivariate analysis was performed using the Logistic stepwise regression model. The life table method was used to calculate survival rates and the Kaplan-Meier method was used to draw survival curves. Log-rank test was used for survival analysis. Results:(1) Case resources: of the 42 hospitals, there were 35 class A of tertiary hospitals and 7 class B of tertiary hospitals, 16 hospitals with high admission of gallbladder cancer and 26 hospitals with low admission of gallbladder cancer, respectively. Geographical distribution of the 42 hospitals: there were 9 hospitals in central China, 5 hospitals in northeast China, 22 hospitals in eastern China and 6 hospitals in western China. Geographical distribution of the 6 159 patients: there were 2 154 cases(34.973%) from central China, 705 cases(11.447%) from northeast China, 1 969 cases(31.969%) from eastern China and 1 331 cases(21.611%) from western China. The total average number of cases undergoing diagnosis and treatment in hospitals of the 6 159 patients was 18.3±4.5 per year, in which the average number of cases undergoing diagnosis and treatment in hospitals of 4 974 patients(80.760%) from hospitals with high admission of gallbladder cancer was 38.8±8.9 per year and the average number of cases undergoing diagnosis and treatment in hospitals of 1 185 patients(19.240%) from hospitals with low admission of gallbladder cancer was 5.7±1.9 per year. (2) Age and sex distribution: the age of 6 159 patients diagnosed as gallbladder cancer was 64(56,71) years, in which the age of 2 247 male patients(36.483%) diagnosed as gallbladder cancer was 64(58,71)years and the age of 3 912 female patients(63.517%) diagnosed as gallbladder cancer was 63(55,71)years. The sex ratio of female to male was 1.74:1. Of 6 159 patients, 3 886 cases(63.095%) were diagnosed as gallbladder cancer at 56 to 75 years old. There was a significant difference on age at diagnosis between male and female patients ( Z=-3.99, P<0.001). (3) Diagnosis: of 6 159 patients, 2 503 cases(40.640%) were initially diagnosed as gallbladder cancer and 3 656 cases(59.360%) were initially diagnosed as non-gallbladder cancer. There were 2 110 patients(34.259%) not undergoing surgical treatment, of which 200 cases(9.479%) were initially diagnosed as gallbladder cancer and 1 910 cases(90.521%) were initially diagnosed as non-gallbladder cancer. There were 4 049 patients(65.741%) undergoing surgical treatment, of which 2 303 cases(56.878%) were initially diagnosed as gallbladder cancer and 1 746 cases(43.122%) were initial diagnosed as non-gallbladder cancer. Of the 1 746 patients who were initially diagnosed as non-gallbladder cancer, there were 774 cases(19.116%) diagnosed as gallbladder cancer during operation and 972 cases(24.006%) diagnosed as gallbladder cancer after operation. Of 6 159 patients, there were 2 521 cases(40.932%), 2 335 cases(37.912%) and 1 114 cases(18.087%) undergoing ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) examination before initial diagnosis, respec-tively, and there were 3 259 cases(52.914%), 3 172 cases(51.502%) and 4 016 cases(65.205%) undergoing serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis, respectively. One patient may underwent multiple examinations. Results of univariate analysis showed that geographical distribution of hospitals (eastern China or western China), age ≥72 years, gallbladder cancer annual admission of hospitals, whether undergoing ultrasound, CT, MRI, serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis were related factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.45, 1.98, 0.69, 0.68, 2.43, 0.41, 1.63, 0.41, 0.39, 0.42, 95% confidence interval as 1.21-1.74, 1.64-2.40, 0.59-0.80, 0.60-0.78, 2.19-2.70, 0.37-0.45, 1.43-1.86, 0.37-0.45, 0.35-0.43, 0.38-0.47, P<0.05). Results of multivariate analysis showed that geographical distribution of hospitals (eastern China or western China), sex, age ≥72 years, gallbladder cancer annual admission of hospitals and cases undergoing ultrasound, CT, serum CA19-9 examination before initially diagnosis were indepen-dent influencing factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.36, 1.42, 0.89, 0.67, 1.85, 1.56, 1.57, 0.39, 95% confidence interval as 1.13-1.64, 1.16-1.73, 0.79-0.99, 0.57-0.78, 1.60-2.14, 1.38-1.77, 1.38-1.79, 0.35-0.43, P<0.05). (4) Surgical treatment and prognosis. Of the 4 049 patients undergoing surgical treatment, there were 2 447 cases(60.435%) with complete pathological staging data and follow-up data. Cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb were 85(3.474%), 201(8.214%), 71(2.902%), 890(36.371%), 382(15.611%), 33(1.348%) and 785(32.080%), respectively. The median follow-up time and median postoperative overall survival time of the 2 447 cases were 55.75 months (95% confidence interval as 52.78-58.35) and 23.46 months (95% confidence interval as 21.23-25.71), respectively. There was a significant difference in the overall survival between cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb ( χ2=512.47, P<0.001). Of the 4 049 patients undergoing surgical treatment, there were 2 988 cases(73.796%) with resectable tumor, 177 cases(4.371%) with unresectable tumor and 884 cases(21.833%) with tumor unassessable for resectabi-lity. Of the 2 988 cases with resectable tumor, there were 2 036 cases(68.139%) undergoing radical resection, 504 cases(16.867%) undergoing non-radical resection and 448 cases(14.994%) with operation unassessable for curative effect. Of the 2 447 cases with complete pathological staging data and follow-up data who underwent surgical treatment, there were 53 cases(2.166%) with unresectable tumor, 300 cases(12.260%) with resectable tumor and receiving non-radical resection, 1 441 cases(58.888%) with resectable tumor and receiving radical resection, 653 cases(26.686%) with resectable tumor and receiving operation unassessable for curative effect. There were 733 cases not undergoing surgical treatment with complete pathological staging data and follow-up data. There was a significant difference in the overall survival between cases not undergoing surgical treatment, cases undergoing surgical treatment for unresectable tumor, cases undergoing non-radical resection for resectable tumor and cases undergoing radical resection for resectable tumor ( χ2=121.04, P<0.001). (5) Multimodality therapy and prognosis: of 6 159 patients, there were 541 cases(8.784%) under-going postoperative adjuvant chemotherapy and advanced chemotherapy, 76 cases(1.234%) under-going radiotherapy. There were 1 170 advanced gallbladder cancer (pathological staging ≥stage Ⅲa) patients undergoing radical resection, including 126 cases(10.769%) with post-operative adjuvant chemotherapy and 1 044 cases(89.231%) without postoperative adjuvant chemo-therapy. There was no significant difference in the overall survival between cases with post-operative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.23, P=0.629). There were 658 patients with pathological staging as stage Ⅲa who underwent radical resection, including 66 cases(10.030%) with postoperative adjuvant chemotherapy and 592 cases(89.970%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.05, P=0.817). There were 512 patients with pathological staging ≥stage Ⅲb who underwent radical resection, including 60 cases(11.719%) with postoperative adjuvant chemotherapy and 452 cases(88.281%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemo-therapy and cases without post-operative adjuvant chemo-therapy ( χ2=1.50, P=0.220). Conclusions:There are more women than men with gallbladder cancer in China and more than half of patients are diagnosed at the age of 56 to 75 years. Cases undergoing ultrasound, CT, serum CA19-9 examination before initial diagnosis are independent influencing factors influencing initial diagnosis of gallbladder cancer patients. Preoperative resectability evaluation can improve the therapy strategy and patient prognosis. Adjuvant chemotherapy for gallbladder cancer is not standardized and in low proportion in China.
RESUMEN
In recent years, with the continuous studies on tumor metabonomics, more and more results have shown that changes of metabolism play important roles in the occurrence and development of malignant tumor. Carcinogenic factors can destroy the metabolic balance of human body, induce metabolic reprogramming, and then mediate a variety of biological behaviors to partici-pate in the proliferation and invasion of cancer cells. Lipids provide the body with the necessary energy and essential fatty acids, and a variety of lipid molecules and metabolites are involved in cell signal transduction. Lipid metabolism is an important link in the metabolic system of the body, and the relationship between the occurrence and development of pancreatic cancer and lipid metabo-lism is not clear. The purpose of this paper is to reveal the changes of lipid metabolism in pancreatic cancer, summarize some preclinical studies and clinical trials, and deeply explain the research status of abnormal lipid metabolism associated with pancreatic cancer, so as to provide new ideas for the study of pancreatic cancer pathogenesis and accurate treatment.
RESUMEN
Objective:To explore the effect of play-based communication and behavior intervention (PCBI) on internalizing and externalizing behaviors in children with autism spectrum disorder (ASD).Methods:From November 2018 to November 2021, 90 ASD children aged 8-30 months who registered in the Child Mental Health Research Center of the Affiliated Brain Hospital of Nanjing Medical University for PCBI ultra-early intervention training were selected and randomly assigned to the intervention group( n=60) and the waiting group( n=30) according to the ratio of 2∶1.Behavioral videos of free play between children and caregivers were collected before and after the 12-week intervention and the behavioral observation and analysis system (Observer XT) was used to code the parent-child interaction status and children's internalizing and externalizing behaviors.SPSS 23.0 statistical software were used and the data were analyzed by t-test, chi-square test, Pearson correlation analysis and multiple linear stepwise regression analysis. Results:After the intervention, the children in the intervention group had improved internalizing and externalizing behaviors (2.43±2.22, 1.88±1.91) compared with those before the intervention (4.82±3.37, 3.68±5.68), and the difference was statistically significant ( t=4.66, 2.60, both P<0.05). The children in the waiting group had no significant difference in internalizing and externalizing behaviors before (4.23±2.47, 4.00±2.18) and after intervention (4.37±2.57, 4.67±3.72) ( t=-0.23, -0.83, both P>0.05). After intervention, the children in the intervention group had fewer internalizing and externalizing behaviors than those in the waiting group, and the difference was statistically significant ( t=-3.70, -4.71, both P<0.05). The differences in internalizing behaviors (2.38±3.96, 1.80±5.37) and externalizing behaviors (1.80±5.37, -0.67±4.38) between the two groups before and after the intervention were statistically significant ( t=3.03, 2.18, both P<0.05). The results of multiple linear stepwise regression showed that the negative interaction of caregivers ( β=0.29, P<0.01) was a risk factor for internalizing behaviors.The negative interaction of children ( β=0.45, P<0.01) was a risk factor for externalizing behaviors, and the child's object status ( β=-0.30, P<0.01) and binary interaction ( β=-0.39, P<0.01) were protective factors for externalizing behaviors.In the intervention group, active child interaction, active caregiver interaction, and binary interaction increased after the intervention ( t=-6.77, -4.58, -7.72, all P<0.05), while the child's object status and the caregiver's negative interaction decreased ( t=3.37, 4.30, both P<0.05). Conclusion:The PCBI ultra-early intervention can effectively improve the internalizing and externalizing behaviors of ASD children.Improvements in internalizing behaviors may work by reducing negative caregiver interactions, and improvements in externalizing behaviors may work by increasing parent-child binary interactions.
RESUMEN
The method of homogeneity evaluation for active pharmaceutical ingredient (API) spatial distribution in lyophilized product was investigated for the first time with confocal micro-Raman spectroscopy mapping, using pemetrexed disodium for injection as a model drug. Certain areas of the lyophilized product were scanned to obtain Raman spectra. The classical method ("peak clipping" method) was employed for mapping with characteristic Raman peaks of the API and the excipient. Due to the API being finely dispersed in the excipient in lyophilized products, the classical method cannot discriminate between the two ingredients making the distribution homogeneity difficult to evaluate. The "ratio of characteristic peak intensities" method was then utilized. Using this method, the relative intensity of the characteristic Raman peaks of the API to the excipient was applied for mapping and the relative content of API to excipient was calculated for a homogeneity evaluation of the drug distribution. The validation of this method showed a good linear relationship between the relative intensity and the relative content of API to excipient (r2 > 0.99), and the precision and recovery were adequate for homogeneity evaluation of API by Raman spectroscopy mapping. Five products of pemetrexed disodium for injection from different manufacturers were tested through Raman maps applying this method and the histograms of relative Raman intensity were also plotted by frequency to help the homogeneity evaluation of drug distribution. The results showed that there were obvious differences in the drug distribution homogeneity from different products, where a more homogeneous API distribution was found in the brand product. This research provides a reliable method for the homogeneity evaluation of API distribution, which facilitates quality evaluation and process optimization of lyophilized products.
RESUMEN
Aim To explore the feasibility of the micro- dynamic chromogenic method for quantitative detection of bacterial endotoxin in recombinant novel coronavirus vaccine ( CHO cell).Methods The micro-dynamic color method of Limulus reagent was used to establish a bacterial endotoxin standard curve.The dilution factor was determined through interference pre -experiment, the recoverv rate of the endotoxin added to the test so- J lution was determined, and the interference test to complete the quantitative detection test of the bacterial endotoxin content in the test product was performed, and the results were compared with those of the gel-clot method.Results Hie linear range of the concentration of the standard curve was 0.02 to 2.0 EU • mL 1 , and the regression equation of the standard curve was lgT =-0.302 7 lgC +2.858 7( r = 0.998 9).When recombinant novel coronavirus vaccine ( CHO cell) was cliluted 40 times or below, the micro -dynamic chromogenic reagent did not interfere with the bacterial endotoxin agglutination reaction, and the recovery rate was 50% to 200%.The test results were consistent with the gel- clot method.Conclusions The micro-dynamic chromogenic method can be used for the quantitative detection of bacterial endotoxins in recombinant novel coronavirus vaccine ( CHO cell) with accurate results, high sensitivity, and process monitoring.
RESUMEN
Objective:To investigate the predictive value of stress hyperglycemia for the functional outcomes in patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to the Affiliated Hospital of Lianyungang, Xuzhou Medical University from September 1, 2019 to December 31, 2020 were enrolled prospectively. The glucose to glycated hemoglobin ratio (GAR) was used to express stress hyperglycemia. The functional outcome was evaluated by the modified Rankin Scale at 3 month after discharge, 0-2 was defined as a good outcome and >2 as a poor outcome. Multivariate logistic regression analysis was used to determine the independent related factors of functional outcome. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of GAR for poor functional outcome. Results:A total of 1 286 patients with AIS were included. Their median age was 67 years old, and 762 were males (59.3%). The median baseline National Institutes of Health Stroke Scale (NIHSS) score was 2. The median fasting blood glucose level was 5.48 mmol/L, the median glycosylated hemoglobin was 6.00%, and the median GAR was 0.92. Eight hundred and twelve patients (63.1%) had good outcomes and 474 (36.9%) had poor outcomes. The GAR in the good outcome group was significantly lower than that in the poor outcome group (0.86 vs. 1.03; P<0.001). All patients were divided into 4 groups (GAR1, GAR2, GAR3, and GAR4) according to the GAR quartile from low to high. Multivariate logistic regression analysis showed that after adjusting for relevant confounding factors, GAR4 (taking the GAR1 as a reference, odds ratio [ OR] 8.896, 95% confidence interval [ CI] 5.775-13.702; P<0.001), age ( OR 1.041, 95% CI 1.027-1.055; P<0.001) and baseline NIHSS score classification ( OR 25.898, 95% CI 14.221-47.163; P<0.001) were closely associated with the poor outcomes at 3 months. Further subgroup analysis showed that the higher level of GAR was significantly and independently correlated with the poor functional outcome, regardless of whether the patients had diabetes or not. The ROC curve analysis showed that the area under the curve of GAR predicting poor outcome at 3 months was 0.705 (95% CI 0.675-0.735; P<0.001), and the predictive value was significantly higher than that of glycosylated hemoglobin and fasting blood glucose. When the cut-off value of GAR was 0.97, the Yoden index was the largest, which was 0.370. The sensitivity and specificity of its predicting the poor outcome at 3 months were 61.6% and 75.4%. Conclusion:Whether or not diabetes is present, GAR is an independent predictor of the poor outcomes in patients with AIS.
RESUMEN
Pancreatic cancer is a rapidly progressive and highly malignancy of the digestive system. In recent years, the diagnosis and treatment of pancreatic cancer has been in a slow stage of development, and the 5-year survival rate of patients remains very low. The main objective of translational medicine is to remove the barriers between basic medical research and clinical medical applications, to achieve practical integration between laboratory and clinic, and to accelerate the translation of the results obtained from basic research into clinical diagnosis, evaluation and treatment of diseases, thus promoting the development of life sciences. With the rapid development of the concept and technology of translational medicine, its application in the early diagnosis of pancreatic cancer can bring new hope for effectively improving the overall prognosis of patients.

Chronic pancreatitis (CP) is a chronic inflammatory and fibrotic disease of the pancreas caused by a variety of causes. The basic treatment principle of CP is to remove the etiology, control the symptoms, improve the pancreatic secretory function and prevent the complications. At present, more and more studies have been conducted on CP treatment strategies. The step-up approach and the surgery first approach are both effective strategies for CP treatment. In clinical practice, endoscopic intervention can be the preferred treatment for pancreatic pseudocyst, pancreatic duct stone, and biliary stenosis. Partington operation is the first choice for dilated main pancreatic duct patients without pancreatic head lesion. Patients with pancreatic head lesions should be intervened with the Beger or Frey operation. For patients without main pancreatic duct dilatation, pancreatectomy should be performed according to the specific lesion location. The total pancreatectomy is advisable for patients with total pancreatic inflammatory disease or multiple lesions of pancreas. Surgeons should follow the individualized and multidisciplinary treatment concepts and strategies in choosing surgical procedures, especially for the control of surgical indications, timing and methods. The authors comprehensively analyze the research progress at home and abroad, elaborate the endoscopic treatment and surgical intervention strategies of CP in order to further optimize the overall efficacy of CP.
RESUMEN
Chronic pancreatitis (CP) is characterized by progressive pancreatic fibrosis, which can lead to irreversible pancreatic endocrine and exocrine dysfunction. Previous reported studies suggested that in patients with CP, there are varying degrees of intestinal bacteria imbalance. In addition, intestinal bacteria have been found to associate with a variety of fibrosis-related diseases. The purpose of this study is to analyze the possible mechanisms of intestinal bacteria in progression of pancreatic fibrosis in CP, by investigating regulation of intestinal barrier, regulation of immunity, and synthesis and release of metabolites, to provide further references in exploring the clinical value of intestinal bacteria in diagnosis and treatment of CP.
RESUMEN
Objective:To investigate the acute effect of fructose intake on serum uric acid, plasma glucose, and insulin levels in healthy young adults.Methods:Sixty-four healthy young subjects were recruited, and randomized to 25 g, 50 g, 75 g fructose group, and 75 g glucose group( n=16) by random number table. The anthropometric parameters, blood pressure, heart rate were measured. Several biochemistry parameters were measured, which were serum uric acid, plasma glucose, plasma insulin, serum total cholesterol, triglyceride, low density lipoprotein-cholesterol (LDL-C) at 0, 60, 120, and 180 min before and after ingestion of fructose or glucose. Results:(1) The serum uric acid level after fructose administration increased significantly than after glucose over 3 h, and peaked at 60 min. The increment of uric acid at 60 min and area under curve of uric acid at 3 h after fructose administration were significantly higher than those of glucose. The increment of uric acid at 60 min increased significantly as fructose dose was increased, especially in the 75 g fructose (increment rate of uric acid at 60 min in 25g, 50g, 75g fructose groups were 9.33%, 13.11%, 17.69% vs 0.75% respectively; Areas under curve of uric acid were 1 674.1±410.38, 1 598.3±417.03, 1 504.6±292.46 vs 1 434.8±328.94, P<0.01). (2) The glucose and insulin levels increased after fructose/glucose intake in four groups with top augment in glucose followed by 75 g fructose. The increase peaked at 30 min, began to decline at 120 min, and returned to fasting level at 180 min. The area under curve of insulin at glucose group was significantly higher than those among fructose groups. With the increase of fructose dose, the increment rate of glucose and insulin at 60 min also increased obviously, especially in the 75 g fructose (the increment rates of glucose at 60 min in 25 g, 50 g, 75 g fructose, 75 g glucose were 7.40%, 8.29%, 13.74%, 28.22% respectively; The increment rates of insulin at 60 min were 54.29%, 115.25%, 185.58%, 730.31% respectively, P<0.01). (3) There were no difference of cholesterol, triglyceride, and LDL-C after fructose/glucose ingestion. Conclusion:Acute fructose intake can lead to the increase of uric acid and insulin; Moreover, the increments of uric acid and insulin after fructose consumption were dependent on fructose dose.
RESUMEN
Objective:To assess the association of hemoglobin (Hb) levels with the prevalence of diabetic retinopathy (DR) in patients with type 2 diabetes mellitus (T2DM).Methods:A cross-sectional study. From January 2017 to December 2018, 707 patients with T2DM who were hospitalized in the Department of Internal Medicine of Chu Hsien-I Memorial Hospital & Tianjin Medical University, were included in the study. All patients underwent color photography of the fundus of both eyes with dilated pupils. According to DR diagnostic criteria, patients were divided into DR group and non-DR (NDR) group, with 210 and 497 cases, respectively; DR group was further divided into non-proliferative DR group (NPDR) group and proliferative DR (PDR) group, about 186, 24 cases, respectively. Hb level was detected, single factor analysis of its correlation with DR; logistic regression analysis was used to evaluate the relationship between Hb level and DR risk.Results:The Hb levels of the patients in the NDR group and the DR group were 140.58±17.26 and 132.35±23.48 g/dl; compared with the NDR group, the Hb level of the DR group was significantly lower, and the difference was statistically significant ( t=5.107, P=0.000). In the NDR group, NPDR group, and PDR group, Hb levels of male patients were 149.3±1.01, 142.6±2.35, 132.9±8.44 g/dl, respectively; Hb levels of female patients were 131.7±0.90, 124.0±2.09, 116.8±5.23 g/dl. With the progress of DR, Hb levels of different sexes decreased significantly, and the difference was statistically significant ( P<0.000 1). The results of correlation analysis showed that Hb reduction was an independent risk factor for DR (odds ratio=4.437, 95% confidence interval 2.590-7.603, P<0.000 1). Conclusion:The reduction of Hb in T2DM patients is positively correlated with the severity of DR.
RESUMEN
Acute pancreatitis (AP) is a common clinical acute abdominal disease, usually with local complications such as pancreatic necrosis, pseudocysts, and abdominal abscesses, as well as systemic inflammatory response syndrome and multiple organ dysfunction syndrome. It is dangerous, difficult to treat, and the prognosis is poor. Although significant progress has been made on the pathogenesis of AP, its specific mechanism is still unclear. In the past few decades, many studies have emphasized the role of oxidative stress in acute inflammatory response. This article clarified the role of oxidative stress in the occurrence and development of AP by introducing oxidative stress to break the cellular Ca 2+ balance, participate in the stimulation of transcription factor activation and excessive release of inflammatory mediators and introduces the application of antioxidant adjuvant therapy in the treatment of AP.
RESUMEN
Pancreatic neuroendocrine neoplasms are a kind of potential malignant neoplasms originating from pancreatic neuroendocrine cells with high heterogeneity and good biological behavior and prognosis. Surgical treatment is considered to be the most important and the only way to cure pancreatic neuroendocrine neoplasms, but there are still many controversies on the treatment. Not only the nature, volume, location, number, invasion of surrounding organs and blood vessels, lymph nodes and distant metastasis of the tumor should be fully evaluated, but also the risk of pancreatic surgery and patients’ own conditions should be taken into account. In this paper, the progress of surgical treatment of pancreatic neuroendocrine tumors in recent years is reviewed.
