ABSTRACT
Objective:To analyze the risk factors of clinically significant bleeding in patients with severe acute pancreatitis (SAP).Methods:The clinical data of SAP patients who were managed at Changhai Hospital affiliated to Naval Medical University from January 1, 2014 to October 31, 2022 were retrospectively analyzed. Twenty-nine SAP patients with clinically significant bleeding were classified to form the bleeding group. There were 23 males and 6 females, aged (56.25±14.01) years old. Another 116 SAP patients with similar general data but with no clinically significant bleeding during the same hospitalization period were included to form the non-bleeding group based on a ratio of 1∶4. There were 94 males and 22 females, aged (56.14±13.96) years old in this non-bleeding group. The general data, modified CT severity index (MCTSI), bedside index for severity of acute pancreatitis (BISAP) and other clinical data of the two groups were collected to determine the risk factors of bleeding in SAP patients.Results:Of the 29 patients with bleeding, 6 had gastrointestinal bleeding, 14 had intra-abdominal bleeding, and 9 had mixed bleeding sites, 15 were cured and discharged, and 14 died. All the 29 SAP patients with bleeding received treatment using drugs. In addition, 8 patients underwent successful hemostasis using digital subtraction angiography, 3 underwent successful endoscopic hemostasis, 2 underwent successful surgical hemostasis, and 2 underwent successful conservative drug hemostasis. Multivariate logistic regression analysis showed that SAP patients with higher MCTSI ( OR=1.824, 95% CI: 1.187-2.802), longer prothrombin time (PT) ( OR=3.431, 95% CI: 1.470-8.007) and higher BISAP ( OR=2.286, 95% CI: 1.054-4.957) had an increased risk of bleeding (all P<0.05). Conclusion:The prognosis of SAP patients was compromised with bleeding. High MCTSI, prolonged PT, and high BISAP were independent risk factors for bleeding in SAP patients.
ABSTRACT
Objective:To evaluate the efficacy and safety of omeprazole and sodium bicarbonate suspension in the treatment of peptic ulcer.Methods:This present study was a multicenter, randomized, double-blind, double-dummy, positive drug parallel controlled phase Ⅱ clinical trial. According to different indications, the trial was divided into gastric ulcer (GU) and duodenal ulcer (DU) studies. Patients were stratified-block randomly divided with a 1∶1 ratio into experimental group and control group. The patients in the experimental group were administrated with omeprazole and sodium bicarbonate suspension omeprazole (20 mg for DU or 40 mg for GU, and 1 680 mg sodium bicarbonate) once a day. The patients in the control group received omeprazole magnesium enteric-coated tablet20 mg for DU or 40 mg for GU once a day. The treatment period was 4 weeks for DU and 8 weeks for GU. The main efficacy indicator was ulcer healing rate under endoscopy. The time of pain disappearance and the total effective rate of clinical symptom relief were used as the secondary efficacy indicators, and the incidence of adverse reactions was used as the safety indicator. The data set included full analysis set (FAS), per-protocol set (PPS) and safety set (SS). Independent sample t test, Wilcoxon rank sum test, chi square test, Fisher exact test method and non-inferiority test were used for statistical analysis. Results:Two hundred and seventy two DU patients and 237 GU patients were included in the FAS, 247 DU patients and 201 GU patients were included in the PPS, and 272 DU patients and 235 GU patients were included in the SS. The results of FAS analysis showed that after 4 weeks treatment, the healing rate of DU under endoscopy in the experimental group was 91.91% (125/136) and that in the control group was 94.85% (129/136), and the difference was not statistically significant ( P>0.05). After 8 weeks treatment the healing rate of GU under endoscopy in the experimental group was 86.44% (102/118) and that in the control group was 87.39% (104/119), and the difference was not statistically significant ( P>0.05). The results of non-inferiority analysis showed the lower limit of 95% confidence interval of difference in effective rate between the two groups was over -10% (-8.84% for DU and -9.54% for GU), which indicated that the effective rate of experimental group was not inferior to that of the control group. The results of PPS analysis were consistent with the results of FAS. The results of FAS analysis showed the median time of abdominal pain disappearance of DU patients in the experimental group and the control group was both 6 d, and the difference was not statistically significant ( P>0.05). The median time of abdominal pain disappearance of GU patients in the experimental group and the control group was both 8 d, and the difference was not statistically significant ( P>0.05). After 4 weeks of treatment, the total effective rates of clinical symptom relief of DU of the trial group and the control group were 95.59% (130/136) and 97.79% (133/136), respectively, and the difference was not statistically significant ( P>0.05). After 8 weeks of treatment, the total effective rates of clinical symptom relief of GU of the experimental group and the control group were 95.76% (113/118) and 93.28% (111/119), respectively, and the difference was not statistically significant ( P>0.05). The results of SS analysis showed that the incidence of adverse reactions of DU patients in the trial group and the control group was 5.15% (7/136) and 2.21% (3/136), respectively, and the difference was not statistically significant ( P>0.05). The incidence of adverse reactions of GU patients in the experimental group and the control group was 12.71% (15/118) and 6.84% (8/117), respectively, and the difference was not statistically significant ( P>0.05). Conclusions:Omeprazole and sodium bicarbonate suspension is not inferior to omeprazole magnesium enteric-coated tablet in healing efficacy under endoscopy in peptic ulcer, and has a good safety.
ABSTRACT
Objective:To explore the efficacy and safety of Ganhai Weikang capsule (GWC) in the treatment of functional dyspepsia (FD).Methods:A randomized, double-blind, placebo-controlled parallel, multi-center, superiority clinical trial was conducted. From March 2018 to April 2020, totally 324 patients with dyspepsia symptoms, who were diagnosed as chronic non-atrophic gastritis by endoscopy and pathology and met the Rome Ⅳ diagnostic criteria for FD from 7 top hospitals were enrolled, including the First Affiliated Hospital of Naval Medical University (Shanghai Changhai Hospital), Heilongjiang Hospital of Traditional Chinese Medicine, Tianjin Academy of Traditional Chinese Medicine Affiliated Hospital, Qilu Hospital of Shandong University, the First Affiliated Hospital of Zhejiang University, Beijing Hospital of Traditional Chinese Medicine of Capital Medical University and the Third Xiangya Hospital of Central South University. The patients were randomly divided into the GWC group and the placebo group according to the ratio of 1∶1. The patients of GWC group were given GWC and the patients of placebo group were given GWC capsule simulant. The patients of both groups orally took capsules before meals, 2.4 g each time and 3 times per day, and the course of treatment was 4 weeks. The main efficacy index was the total clinical effective rate after 4 weeks, and the secondary efficacy index was the changes of clinical symptom scores of upper abdominal pain, upper abdominal burning, postprandial fullness and early satiety. The safety index included laboratory tests and adverse events. Chi-square test and Wilcoxon rank sum test were used for statistical analysis.Results:A total of 320 FD patients were enrolled in the full analysis set (FAS), which included 161 cases in GWC group and 159 cases in placebo group. A total of 298 cases were in the per-protocol set (PPS), 149 cases each in GWC group and placebo group. The results of FAS and PPS both showed that the total clinical effective rates of the GWC group were higher than those of the placebo group (84.5%, 136/161 vs. 44.0%, 70/159 and 83.9%, 125/149 vs. 46.3%, 69/149), and the differences were statistically significant ( χ2=57.07 and 46.32, both P<0.001). In addition, the differences of the total score of main symptoms and each symptom (upper abdominal pain, upper abdominal burning, postprandial fullness and early satiety) before and after treatment of GWC group were all higher than those of the placebo group (FAS: 10 (7, 14) vs. 5 (3, 11); 3 (2, 4) vs. 2 (0, 3); 2 (0, 4) vs. 1 (0, 3); 3 (1, 4) vs. 2 (1, 3); 2 (0, 4) vs. 1 (0, 3). PPS: 10 (7, 13) vs. 5 (3, 11); 3 (2, 4) vs. 2 (0, 3); 2 (0, 4) vs. 1 (0, 2); 3 (1, 4) vs. 2 (1, 3); 2 (0, 4) vs.1 (0, 3)), and the differences were statistically significant (FAS: Z=5.80, 5.91, 3.19, 3.72 and 3.30; PPS: Z=5.14, 5.11, 2.86, 3.21 and 2.84; all P<0.01). The results of FAS and PPS indicated that the improvement rates of main symptoms and each symptom (upper abdominal pain, upper abdominal burning, postprandial fullness and early satiety) of GWC group were all higher than those of the placebo group (FAS: 77.8% (54.6%, 91.3%) vs. 42.9% (28.6%, 61.5%); 100.0% (60.0%, 100.0%) vs. 50.0% (25.0%, 60.0%); 100.0% (50.0%, 100.0%) vs. 50.0% (25.0%, 100.0%); 71.4% (33.3%, 100.0%) vs. 41.4% (25.0%, 66.7%); 100.0% (50.0%, 100.0%) vs. 50.0% (20.0%, 100.0%). PPS: 77.8% (54.2%, 89.5%) vs. 44.0% (28.6%, 65.0%); 100.0% (60.0%, 100.0%) vs. 50.0% (25.0%, 100.0%); 100.0% (50.0%, 100.0%) vs. 50.0% (25.0%, 100.0%); 71.4% (33.3%, 100.0%) vs. 46.4% (25.0%, 66.7%); 100.0% (50.0%, 100.0%) vs. 50.0% (20.0%, 100.0%)), and the differences were statistically significant (FAS: Z=8.60, 7.72, 4.98, 4.24 and 5.61; PPS: Z=7.90, 7.03, 4.49, 3.88 and 4.83; all P<0.001). After 2 weeks of treatment, the differences of the total score of main symptoms and score of each symptom (upper abdominal pain, upper abdominal burning and early satiety) before and after treatment of GWC group were all higher than those of the placebo group (5.0 (3.0, 8.0) vs. 4.0 (2.0, 6.0); 2.0 (1.0, 2.0) vs. 2.0 (0.0, 2.0); 1.5 (0.0, 2.0) vs. 1.0 (0.0, 2.0); 1.5 (0.0, 2.0) vs. 1.0 (0.0, 2.0)), and the differences were statistically significant ( Z=2.95, 3.44, 2.43 and 2.79, all P<0.05). There was no significant difference in the incidence of adverse events between the GWC group and the placebo group (0.6%, 1/163 vs. 0, 0/159). Conclusion:The clinical total effective rate of GWC in the treatment of FD is superior to that of placebo and it has good safety.
ABSTRACT
Pancreatic neuroendocrine neoplasms (pNENs) are highly heterogeneous, and the management of pNENs patients can be intractable.

By reviewing the important issues regarding the diagnosis and treatment of pNENs, the committee concluded evidence-based statements and recommendations in this article, in order to further improve the management of pNENs patients in China.
ABSTRACT
Objective:To investigate the predictive value of acute gastrointestinal injury (AGI) score for the severity of acute pancreatitis (AP), infectious pancreatic necrosis and patients′ death.Methods:Clinical data of 719 patients with AP were collected from the AP database of the National Clinical Research Center for Digestive System Diseases from January 2016 to June 2018. According to the severity of the disease, they were divided into MAP group (506 cases), MSAP group (112 cases) and SAP group (101 cases). AGI, APACHEⅡ, MCTSI and BISAP scores were calcululated in the three groups. Receiver operating characteristic curve (ROC) was drawn and the area under the curve (AUC) was calculated. The predictive value of the above four scoring systems for the hospitalization days, disease severity, infectious pancreatic necrosis and death was analyzed, respectively.Results:There were no cases of infectious pancreatic necrosis or death in the MAP group, but there were 9 cases of infectious pancreatic necrosis and 2 deaths in the MSAP group and 19 cases of infectious pancreatic necrosis and 8 deaths in the SAP group. There was a strong correlation between AGI score and AP patients′ hospitalization days ( r=0.619). AUC of AGI, APACHEⅡ, MCTSI and BISAP score in predicting the AP patients′ severity (MSAP+ SAP) was 0.967 (95% CI 0.951-0.982), 0.769(95% CI 0.720-0.899), 0.842(95% CI 0.809-0.875), 0.862 (95% CI0.832-0.893). AUC for forecasting infectious pancreatic necrosis was 0.803, 0.677, 0.692, 0.724, and the 95% CI was 0.724-0.882, 0.573-0.781, 0.582-0.636, 0.801-0.812. AUC for predicting death in patients with AP were 0.915, 0.597, 0.659, 0.812, and the 95% CI were 0.843-0.986, 0.444-0.751, 0.498-0.698 and 0.882-0.926. AGI score had the highest predictive value, followed by BISAP score, and the correlation between these two scores was the closest. The predictive value of AGI combined with BISAP score for infectious pancreatic necrosis and patient death (AUC were 0.837, 0.942, 95% CI were 0.770-0.903, 0.897-0.987) was better than that of AGI and BISAP score alone. Conclusions:AGI score combined with BISAP score is more effective in predicting the severity of AP, the occurrence of infectious pancreatic necrosis or patient death.
ABSTRACT
Objective:To explore the expression of miR-216a in patients with acute pancreatitis (AP) associated with acute lung injury (ALI) and its influence on endothelial cells permeability.Methods:40 AP patients admitted in Department of Gastroenterology of the First Affiliated Hospital of Navy Medical University from December 2015 to March 2016 were collected and were classified into AP with ALI (AP-ALI group, n=13) and AP without ALI (AP group, n=27) according to the presence or absence of ALI. 8 normal volunteers were enrolled in the control group. Blood samples were collected and the plasma samples were separated. Plasma RNA was extracted. miR-216a level in plasma was detected by RT-PCR. Plasma exosomes were extracted by exosome extraction kit and identified by the electron microscopy. Exosome RNA was extracted. miR-216a level in exosome was detected by RT-PCR. Plasma exosomes of AP-ALI patients were co-cultured with human umbilical vein endothelial cells (HUVEC, AP-ALI-HUVEC group) and anti-miR-216a transfected HUVECs (AP-ALI-anti-miR-216a HUVEC group) for 24 hours, respectively, and untreated HUVECs served as control group. Trans-endothelium electrical resistance (TEER) was measured by Millicell Ers-2 epithelial volt-ohmmeter to evaluate the cell permeability. Results:RT-PCR results showed that the expression level of plasma miR-216a in AP-ALI group (14.45±1.64) was significantly higher than that in AP group (11.08±1.6) and the control group (5.37±1.54) ( P<0.01). Under electron microscope, plasma exosomes were goblet like vacuoles, with the size of about 50-90 nm. The plasma exosomal miR-216a level in the AP-ALI group (14.03±1.58) was significantly higher than that in the AP group (10.86±1.31) and the control group (5.01±0.79), and the difference was statistically significant ( P<0.01). The resistance value of HUVEC in the control group was referred as 1, and the resistance ratio of HUVEC in AP-ALI-HUVEC group was 0.74±0.04, which was significantly lower than that of HUVEC in AP-ALI-anti-miR-216a HUVEC group (1.02±0.08), the difference was statistically significant ( P<0.01). Conclusions:miR-216a was highly expressed in plasma exosomes of AP patients with ALI. miR-216a can increase endothelial cell permeability, which may be associated with ALI during AP.
ABSTRACT
Objective:To analyze the efficacy of blood purification (BP) in the treatment of moderately severe acute pancreatitis (MSAP) and severe acute pancreatitis (SAP).Methods:The clinical data of 102 patients of MSAP and SAP in Changhai Hospital affiliated with Navy Medical University from December 2015 to March 2019 were retrospectively analyzed. According to the treatment method and prognostic outcome, patients were divided into control group ( n=46) and BP group ( n=56), control survival group ( n=43), and control death group ( n=3), BP survival group ( n=37) and BP death group ( n=19), respectively. Based on BP treatment duration each time, BP group was sub-divided into BP short-term group (4 h≤T<8 h, n=38) and BP long-term group (8 h≤T≤12 h, n=18). General data, laboratory findings, complications, average daily hospitalization cost, prognosis and effects of BP duration on the blood urea nitrogen improvement were recorded. Results:Compared with control survival group, BP survival group had lower levels of lactic acid, urea nitrogen and other metabolites, and SIRS duration was significantly shortened [12(7, 16) days vs 5(3, 9) days, HR=0.19, 95% CI 0.11-0.35, P<0.0001]. The clearance of urea nitrogen in BP short-term group was more obvious than BP long-term group (χ 2==4.44, P=0.035). APACHEⅡ score on admission( OR=1.33, 95% CI 1.087-1.617, P=0.005) and numbers of organ failure ( OR=3.445, 95% CI 1.426-8.323, P=0.006) were important risk factors affecting MSAP and SAP prognosis under BP therapy. For patients with extremely poor prognosis, it was still difficult for BP to reverse the progression trend and prognosis of MSAP and SAP. Conclusions:BP can effectively remove accumulated metabolites at acute stage and shorten the duration of SIRS. BP duration of 4-8 h each time may be more conducive for improving the severity of the disease.
ABSTRACT
Objective To investigate the pshcyological status and influencing factors of patients with acute pancreatitis. Methods Acute pancreatitis patients admitted in Changhai Affiliated Hospital of Navy Medical University from December 2018 to February 2019 were enrolled, and 120 patients were selected using random number table method. Self-made general questionnaire, self-rating depressing scale, self-rating anxiety scale and coping style questionnaire were used for investigation and patients′ psychological status was evaluated. Results In this survey, 109 questionnaires were collected and eligible for final analysis. The incidence of depression in patients with acute pancreatitis was 44. 0％, and the incidence of anxiety was 20. 2％. Male patients had significantly lower anxiety and depression than women. The levels of anxiety and depression in the 31-50 age group were significantly lower than those in other age groups. The level of anxiety in patients with pancreatitis with children was significantly lower than in patients without children. The coping style of "solving problem" was significantly negatively correlated with depression and anxiety level. The"self-blame" coping style was significantly positively correlated with depression and anxiety level. The"rationalized"coping style was positively correlated with the level of depression. Conclusions The mental health status of patients with acute pancreatitis was not optimistic. Different coping styles were important factors affecting the level of anxiety and depression.
ABSTRACT
Objective To investigate the early predictive value of several commonly used biochemical markers for predicting persistent organ failure ( POF ) in patients with hyperlipidemic acute pancreatitis ( HLAP) . Methods Clinical data of 157 patients with HLAP within 72 hours after the onset of first attack who were admitted to the Dept. of Gastroenterology in Changhai Hospital from January 2015 to December 2017 were retrospectively analyzed, including 106 cases without POF ( non POF group ) and 51 cases with POF ( POF group) . Hct, BUN, Cr, APACHEⅡand BISAP were recorded within 24 hours after admission. Receiver-operating characteristic ( ROC) curve was drawn to calculate area under the ROC curve ( AUC) and evaluate the performance of Hct, BUN, Cr, APACHEⅡand BISAP scores in predicting HLAP complicated with POF, which was compared by DeLong test. Results Values of BUN, Cr, APACHEⅡand BISAP were significantly higher in HLAP patients with POF than those without POF [(10. 30 ± 7. 43) vs (5. 34 ± 2. 26) mmol/L, (165. 31 ± 123. 93) vs (65. 61 ± 20. 82)μmol/L, (10. 22 ± 6. 22) vs (4. 61 ± 2. 99) points, (2. 61 ± 0. 87) vs (1. 42 ± 1.07) points], and the differences were all statistically significant (all P<0.05), whereas Hct was not significantly different between the two groups. The AUC of Cr and BUN for predicting POF was 0. 77(95％ CI, 0. 69-0. 86) and 0. 71 (95％ CI, 0. 61-0. 81), respectively, and the optimum predictive Cut-off values were 130 μmol/L and 8. 95 mmol/L, respectively. The sensitivity was 53％, and the specificity was 99％ and 94％;the accuracy was 84％ and 81％;negative predictive value was 81％, and positive predictive value was 96％ and 82％. DeLong test showed that predictive performance of BUN and Cr was not statistically different from that of APACHEⅡand BISAP. Conclusions Cr≥130 μmol/L and BUN≥8. 95 mmol/L can be used clinically to predict the presence of POF in HLAP, and the predictive efficacy were comparable to APACHEⅡand BISAP.
ABSTRACT
Objective@#To explore the predictive value of acute gastrointestinal injury(AGI) grading system in assessing the severity, infectious pancreatic necrosis and death of patients with moderate severe acute pancreatitis (MSAP) and severe acute pancreatitis (SAP).@*Methods@#The clinical data of 344 patients with MSAP or SAP admitted in Changhai Hospital Affiliated to Navy Medical University from June 2011 to June 2015 were collected. ROC curve was used and the area under ROC curve (AUC) was calculated. The predictive value of AGI grade for the severity, infectous pancreatic necrosis and death was compared with those of different clinical scores(APACHEⅡ score, MCTSI and Marshal score).@*Results@#Of 344 patients, 81 patients were classified into high AGI grade group (Grade Ⅲ, Ⅳ), while 263 patients were in low AGI grade group(Grade Ⅰ, Ⅱ).

AUC of high AGI grade for predicting patients′ death and infectious pancreatic necrosis was 0.944(95% CI 0.916-0.972) and0.779(95% CI 0.723-0.836), respectively, which was higher than those of APACHEⅡ and Marshall score.@*Conclusions@#AGI grading system can be applied to better assess the severity of acute pancreatitis, and its predictive value for death and infectious pancreatic necrosis was higher than that of APACHEⅡ, MCTSI and Marshall score.
ABSTRACT
Objective@#To compare the therapeutic value of transnasal gastroscopy and conventional gastroscopy for infective pancreatic necrosis(IPN) through percutaneous endoscopic necrosectomy(PEN).@*Methods@#A total of 24 IPN patients who received PEN for IPN from December 2015 to March 2019 were divided into the conventional gastroscopy group (n=15) and the transnasal gastroscopy group (n=9). The clinical therapeutic indicators such as vital signs, APACHE Ⅱ score changes, operation duration, difference in preoperative and postoperative volumes of peripancreatic necrosis and other indicators were compared between the two groups.@*Results@#There was no significant difference in the variation curve fitting of APACHE Ⅱ scores between the two groups (t=0.378, P=0.710). The operation time of the transnasal gastroscopy group was significantly shorter than that of the conventional gastroscopy group (119.7±47.4 min VS 172.8±56.2 min, P=0.018). Peripancreatic necrotic volume significantly decreased after operation in the transnasal gastroscopy group (404.03±170.73 mL VS 468.9±137.37 mL, P=0.002), and in the conventional gastroscopy group (499.44±227.17 mL VS 722.50±292.96 mL, P<0.001). There was no significant difference in the decrease extent in the conventional gastroscopy group and the transnasal gastroscopy group (223.06±212.92 mL VS 64.87±54.94 mL, P= 0.094).@*Conclusion@#On the condition of poor drainage of percutaneous catheter drainage, PEN can significantly reduce the range of necrotic lesions. Transnasal gastroscopy has the advantages in operation time in PEN and clearing deep abscess cavities over conventional gastroscopy.

Objective To investigate the impact of the initial fluid resuscitation with different ratio of crystalloid and colloid on the prognosis of patients with moderate severe acute pancreatitis (MSAP).Methods A retrospective analysis was made by reviewing the clinical data of 72 patients with the diagnosis of MSAP from January 2015 to July 2017 in Shanghai Changhai Hospital.According to crystalloid-colloid ratio,which was the total volume of crystalloid fluid versus colloid fluid in the first 7d at admission,patients were randomly divided into low crystalloid-colloid ratio group (＜ 4.5),middle crystalloid-colloid ratio group (4.5-7.5),and high crystalloid-colloid ratio group (＞ 7.5).The parameters of the fluid resuscitation,the cases progressing into severe acute pancreatitis (SAP),the incidence of multiple organs dysfunction syndrome (MODS) and mechanical ventilation,pancreatic necrosis and infection rate,30-day mortality,the duration of systemic inflammatory response syndrome(SIRS) and the time reaching full amount of enteral nutrition were analyzed.Results There was no statistically significant difference in gender,age,etiology and APACHE Ⅱ score within 24 h at admission in each group,which were comparable.Within the first 7 d,there were no statistic difference in the total volume of fluid infusion and the speed of resuscitation in the three groups.While the total fluid volume in the first 24 h and 72 h [(3 095 ± 1 253) ml vs (2 524 ± 751) ml,(8 005 ± 7 269) ml vs (6 667 ± 1 498)ml],the total volume of crystalloid fluid in the first 7 d [(14 485 ± 3 917) ml vs (11 544 ±2 639) ml],crystalloid-colloid ratio (12.7 ± 4.9 vs 6.0 ± 1.0),the cases of SAP (12 vs 4),MODS (41.7 ％vs 16.0％) in high ratio group were significantly higher than those in middle ratio group,but the total volume of colloid fluid was significantly lower [(996 ± 528) ml vs (1 968 ± 574) ml].In addition,the duration of SIRS [(16.5 ± 15.2) d vs (8.2 ± 6.4) d],and the time reaching full amount of enteral nutrition [(7.2 ±3.6) d vs (4.8 ± 2.4) d] in high crystalloid-colloid ratio group were higher than those in middle crystalloid-colloid ratio group (all P ＜ 0.05).Comparing with middle crystalloid-colloid ratio group,there were no significant difference in the mechanical ventilation rate,pancreatic necrosis and infection rate and 30-day mortality in high ratio group.The total volume of colloid fluid was significantly higher [(3 680 ± 1 310) vs (1 968 ±574)] and the crystalloid-colloid ratio was significantly lower [(3.2 ±0.9) vs (6.0 ± 1.0)] in low ratio group than that in middle ratio group,and there were no statistical differences on other parameters.Conclusions For the patients with MSAP,early fluid resuscitation with the crystatloid-colloid ratio of (4.5-7.5) can decrease the incidence of SAP and MODS,shorten the duration of SIRS,and promote the recovery of intestinal mucosal barrier function.
ABSTRACT
Objective To evaluate the diagnostic value of gastrin?17( G?17) and pepsinogen( PG) for gastric cancer. Methods A multicenter cross?sectional study of patients with continuous stomach discomfort from four centers including Changhai Hospital Affiliated to Second Military Medical University, the First Hospital Affiliated to Anhui Medical University, Qinghai Provincial People′s Hospital and the First Hospital Affiliated to Zhejiang University of Chinese Medicine from May 2014 to September 2015 was conducted. Before gastroscopy, fasting serum gatrin?17 and pepsinogen were analyzed by enzyme?linked immunosorbent assay(ELISA). The efficacy of G?17 and PG were evaluated according to endoscopic and pathological results. Results Based on the results of the pathological diagnosis, 1 122 cases were enrolled and divided into chronic atrophic gastritis group ( 548 cases ) , chronic non?atrophic gastritis group ( 370 cases), and gastric cancer group(204 cases). Serum G?17 and PGⅡ levels significantly increased(P7 pmol/L and PGR7 pmol/L and PGⅡ>10μg/L was regarded as the cut?off value, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 48?04%, 79?74%, 73?98%, 34?51% and 87?35% respectively. If PGR10 μg/L was regarded as the cut?off value, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 33?82%, 84?86%, 75?58%, 33?17% and 85?23% respectively. Based on logistic regression analysis of the independent variables of high serum G?17 value(>7 pmol/L), low serum PGR value(10 μg/L), their OR value were 2?592, 2?237 and 1?864 respectively, and high serum G?17 value showed the highest risk of gastric cancer. Conclusion High serum G?17 and PGⅡ, low PGR are indicators of gastric cancer. Combination of G?17 and PGR has the best diagnostic value for gastric cacer. Gastric cancer can be screened in large scale by combining G?17 and PGR in order to improve the early diagnostic rate of gastric cancer and reduce the mortality of gastric cancer in our country.
ABSTRACT
Background: Chronic atrophic gastritis (CAG) is a precancerous lesion of gastric cancer.The diagnostic value of serum gastrin-17 (G-17) level for CAG differs substantioulsy, and Helicobacter pylori (Hp) infection may play an important role.Aims: To explore the effect of Hp infection on serum G-17 level, and the diagnostic value of serum G-17 level for CAG under different Hp infection status.Methods: A total of 204 patients with chronic non-atrophic gastritis and 81 patients with CAG from May 2014 to May 2015 at the three different hospitals were enrolled.Gastroscopy was performed, fasting serum G-17 level, postprandial serum G-17 level and Hp-IgG antibody were determined by ELISA.Results: Fasting serum G-17 level was significantly increased in Hp positive group than in Hp negative group (P=0.001), and postprandial serum G-17 level was significantly decreased in CAG group than in non-atrophy group (P=0.002).AUC of fasting serum G-17 level for diagnosing Hp positive and negative CAG were 0.634 (95% CI: 0.537-0.732) and 0.576 (95% CI: 0.478-0.675), respectively, the accuracy were 62.6% and 54.9%, respectively.AUC of postprandial serum G-17 level for diagnosing Hp positive and negative CAG were 0.675 (95% CI: 0.581-0.769) and 0.595 (95% CI: 0.495-0.694), respectively, the accuracy were 61.8% and 53.1%, respectively.Conclusions: Hp infection has impact on serum G-17 level, as a result, the diagnostic value of G-17 level for CAG is different for patients with and without Hp infection.Diagnostic values of fast and postprandial serum G-17 for Hp positive CAG are higher than Hp negative CAG.
ABSTRACT
Objective To evaluate the therapeutic effect of percutaneous endoscopic necrosectomy (PEN) in treating infectious pancreatic necrosis (IPN).Methods A retrospective review of clinical data of 6 patients with IPN who received PEN in Changhai Hospital, Second Military Medical University from Dec 2015 to Sep 2016 was performed.Clinical parameters were recorded, including basic information, severity evaluation and therapeutic methods and times.In addition, vital sign parameters and inflammatory marks before and after PEN treatment were compared.Results There were 4 patients with severe acute pancreatitis (SAP) and 2 patients with moderately severe acute pancreatitis (MSAP) in these 6 patients with IPN.Mean APACHEⅡ score was 12 (10~15), and mean MCTSI scores was 9.3(8~10).All 6 patients received a total of 13 times PEN treatments, with a mean of 2.2(1~3) times.Each patient was treated with a mean of 2.5(1~4) drainage tubes placed in the peripancreatic abscess after PEN treatment, and the mean time for drainage was 139 d(106~183 d).Besides, the mean hospitalization time was 116 d (48~223 d).All the patients′ condition was improved significantly after PEN treatment, including reduced heart rate, body temperature and inflammatory markers, without bleeding or other serious complications.Only 1 patient had pancreatic fistula after treatment, and no patients needed open abdominal drainage surgery.Patients with higher MCTSI scores likely required more times of PEN and more drainage catheters, longer length of drainage and hospital stay.Conclusions PEN was safe and effective for treating patient with IPN, but those with higher MCTSI scores were associated with more PEN treatments, more drainage tubes, and longer time of drainage and hospitalization.
ABSTRACT
Objective To evaluate the effectiveness and safety of double balloon enteroscopy( DBE) in retrieval of retained capsule and identify the factors associated with successful retrieval. Methods A total of 23 consecutive retention cases who received retrieval of retained capsules by DBE from January 2010 to December 2013 were reviewed. They were assigned to success group and failure group. The differences in insertion route, insertion depth, lesion location between the two groups were analyzed. Results Fifteen cases of all 23 retention cases were successfully retrieved and the success rate was 65?2%. There was no significant difference in the mean entrapped period of CE between the two groups [20?0(15?0,57?0)d VS 21?0(16?0,240?0) d,P=0?525]. DBE via oral route exhibited remarkable higher success rate than anal route [ 71?4%( 15/21) VS 0/5, P=0?007] . Compared with ileum, it was easier to take out CE located at jejunum( 8/8 VS 7/13, P=0?046 ) and the insertion depth was significantly less in the success group [(167?3±33?8)cm VS (258?3±23?9) cm, P=0?041]. Whether the capsule was in pelvic cavity shown by x?ray film before the surgery was irrelevant to the successful rate(9/14 VS 5/6,P=0?613) and insertion depth of the DBE on access to the capsule[(132?0±68?6) cm VS (200?0±40?3) cm, P=0?376],or to the actual location of the capsule. Conclusion Peroral DBE is an effective method for removal of retained CE and the success rate isn′t relevant to the entrapped period. Retained CE locates in ileum and jejunum is more difficult to be taken out than in duodenum.
ABSTRACT
Objective To evaluate the efficacy and safety of Houpu Paiqi mixture in treatment of functional dyspepsia (FD)with abdominal distension symptom.Methods From July 2014 to June 2015 , in nine centers,a total of 162 FD patients with abdominal distension symptom and met Rome Ⅲpostprandial distress syndrome (PDS)diagnostic criteria were enrolled.All patients were randomly divided into trial group and control group,81 patients in either group.The patients of trial group and control group took Houpu Paiqi mixture or placebo,respectively,25 mL per time,twice daily,and both the courses of treatment were two weeks.Before and after the treatment,the improvement of main symptoms,total clinical efficacy rate and efficacy of traditional medicine between two groups were compared.Chi square test,Fisher exact probability method and Wilcoxon test were performed for statistical analysis.Results According to the results of per-protocol (PP)analysis,the total efficacy rate of trial group and control group was 69.4% (50/72)and 59.2% (42/71),respectively,and there was no statistically significant difference in total efficacy rate between the two groups (χ2 =1 .650,P =0.199 ). And there was no statistically significant difference in the improvement of PDS main symptoms(postprandial fullnessand early satiety)between the two groups (56.3% ±27.9% vs 54.4% ±32.1%,t =0.606,P =0.727 ).For those with baseline symptom score over 14,median early satiety score of trial group after the treatment was 0,which was lower than that of control group,and the difference was statistically significant (Z =-2.370,P =0.018).The total efficacy rate of traditional medicine of trial group was 80.8% (59/73 )and that of control group was 72.0% (54/75 ),and the difference was not statistically significant (χ2 = 0.676,P =0.411 ).Conclusion Houpu Paiqi mixture has certain efficacy in FD with abdominal distension,and could be used for the treatment of PDS-predominant FD.
ABSTRACT
Objective To investigate the risk factors for failure of percutaneous catheter drainage (PCD) for patients with infective pancreatic necrosis (IPN).Methods A retrospective review of medical records of patients with IPN who received PCD at Pancreatic Intensive Care Unit (PICU) of Changhai Hospital from April 2010 to June 2014 was performed.The patients were divided into 2 groups:(1) PCD success group (n =48) and (2) PCD failure group (n =12).The potential parameters for failure of PCD were recorded,which included age,sex,etiology,length of hospital stay,outcome,MCTSI,APACHE Ⅱ scores,number of organ failure,duration of use of antibiotics,duration of use of PPIs,if delayed fluid resuscitation occurred,start of enteral nutrition,nutrition status,etc,and univariate and multivariate logistic regression analysis was used.Results Univariate analysis showed MCTSI,number of organ failure,malnutrition,use of PPIs (more than two weeks),delayed enteral nutrition,delayed fluid resuscitation,the number of drainage catheter,number of aspiration,multi-drug resistant infections of drainage fluid were risk factors for failure of PCD;while multivariate logistic regression analysis showed that MCTSI (OR =3.33;95％ CI 1.52 ～ 7.29;P =0.003);multi-drug resistant infections of drainage fluid (OR =8.62;95 ％ CI 1.11 ～ 67.19;P =0.040) were risk factors for failure of PCD.Conclusions MCTSI and multi-drug resistant infections of drainage fluid can significantly influence the success rate of PCD.PCD should be carefully considered for patients with high score of MCTSI and multi-drug resistant infections of drainage fluid.
ABSTRACT
Objective To evaluate the risk factors,treatment and follow-up of capsule retentions after capsule endoscopy examination.Methods A total of 1 100 capsule enteroscopic examinations,performed at our hospital from October 2006 to March 2013,were retrospectively studied.The positive findings of lesions, clinical indications of capsule endoscopy,treatment and follow-ups were recorded.Results The incidence of capsule retentions was 1.18%(n =13).The rates of capsule retentions in OGIB,suspected Crohn′s disease (CD),known CD,suspected tumors and chronic abdominal pain were 0.95%,4.0%,10.5%,7.1% and 0.3%,respectively.In 11 patients,the capsule was removed by means of double-balloon enteroscopy,the cap-sule was removed surgically in one patient,and spontaneous expulsion occurred in another patient after 1 year of treatment.Risk factors for capsule retention were known or suspected CD and suspected tumor(OR =11.44, P =0.02;OR =5.59,P =0.02),and suspected tumor was also a risk factor(OR =7.42,P =0.04).Conclu-sion Capsule endoscopy is a safe procedure with low risk of capsule retentions.Advantages and disadvantages of capsule endoscopy examinations should be considered carefully when high-risk patients are involved.
