ABSTRACT

OBJECTIVE To study the effects of leonurine on pancreatic injury in rats with severe acute pancreatitis (SAP), and to explore its mechanism based on the high-mobility group box 1 (HMGB1)/receptor for advanced glycation end products (RAGE) signaling pathway. METHODS SAP rat model was constructed by injecting 5% sodium taurocholate into the bile duct of the pancreas. Model rats were randomly divided into model group, low dose leonurine group (8 mg/kg), high dose leonurine group (16 mg/kg), HMGB1 overexpression group (8 μg/kg), and high dose leonurine+HMGB1 overexpression group (16 mg/kg+8 μg/kg), with 14 rats in each group. Another 14 rats were selected as the sham operation group. Rats in each group were injected with corresponding drugs or normal saline via abdominal cavity or tail vein once a day for 5 consecutive days. After the last administration, the levels of serum amylase (AMS) and lipase (LPS) were detected; the pathological injury of pancreatic tissue was observed; the levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), malondialdehyde (MDA) and superoxide dismutase (SOD), mRNA and protein expressions of HMGB1 and RAGE in pancreatic tissues were detected. RESULTS Compared with model group, the structure of pancreatic tissue in rats gradually recovered in low and high dose leonurine groups; inflammatory cell infiltration gradually decreased; the pathological injury score and the levels of AMS, LPS, TNF-α, IL-6, MDA, the mRNA and protein expressions of HMGB1 and RAGE were significantly decreased, while the SOD levels were significantly increased (P<0.05). The high dose leonurine group showed more significant improvement (P<0.05); the pathological damage of pancreatic tissue in the HMGB1 overexpression group worsened, and except for a decrease in SOD levels, all other quantitative indicators increased significantly (P<0.05). Overexpression of HMGB1 could reduce the improvement effect of high dose leonurine on the above indexes in SAP rats (P<0.05). CONCLUSIONS Leonurine may alleviate pancreatic injury, inflammation and oxidative stress in pancreatic tissue of rats with SAP by inhibiting the HMGB1/RAGE signaling pathway.

ABSTRACT

Objective:To establish the best evidence-based approach for early fluid resuscitation management in patients with severe acute pancreatitis (SAP).Methods:A literature search was conducted utilizing evidence-based nursing methods to identify relevant evidence on the management of early fluid resuscitation in patients with SAP. The search followed the hierarchical order of the " 6S" evidence pyramid, including databases such as China National Knowledge Infrastructure (CNKI), China Biomedical Literature Database (SinoMed), Wanfang Database, UpToDate, NICE, RNAO Guidelines Network, Pancreatology International, WHO Association Website, JBI, Cochrane, PubMed, EMBASE, and CINAHL. The search was limited to articles published from the establishment of each database to March 2022. The literature quality evaluation tools and an evidence pre-grading system from the JBI Evidence-Based Health Care Center were employed to assess the quality of the literature included in the study. Additionally, the FAME structure was utilized to evaluate the feasibility, appropriateness, clinical significance, and validity of the evidence.Results:Nine articles were finally incorporated into the analysis, including four guidelines, one evidence summary, two systematic reviews, and two expert consensus articles. 21 pieces of evidence pertaining to early fluid resuscitation management in patients with SAP was summarized, encompassing five key aspects: resuscitation timing, type of fluid infusion, total volume and speed of fluid infusion, dynamic monitoring, and fluid resuscitation goals. It was advisable for patients diagnosed with SAP to promptly receive fluid resuscitation, ideally within 72 hours of diagnosis. The initial choice for fluid resuscitation was lactated Ringer′s solution, with the addition of human albumin as a supplementary colloid solution. The quantity of fluid administered within the first 24 hours of rehydration should constitute approximately 33.3% of the total rehydration volume within the 72 hours time-frame. In the case of patients experiencing early shock or dehydration, it was advised that the fluid rate administered should be 5-10 ml·kg -1·h -1 within the first 24 hours of admission. Additionally, an infusion of 20 ml/kg of fluid can be administered within the initial 30-45 minutes. It was recommended to assess the adequacy of early fluid resuscitation every 4-6 hours, ensuring that the resuscitation objective could meet at least two of the following criteria: urine output of 0.5-1 ml·kg -1·h -1, mean arterial pressure of 65-85 mmHg, central venous pressure of 8-12 mmHg, heart rate below 120 beats/min, central venous oxygen saturation of at least 70%, and a decrease in hematocrit levels to 30%-35%. Conclusions:The most compelling evidence supporting the implementation of early fluid resuscitation management in patients with SAP is derived from an evidence-based nursing approach, which could effectively improve patient care outcomes.

ABSTRACT

Objective:To construct a prognostic model for severe acute pancreatitis (SAP) based on CT scores and inflammatory factors, and to evaluate its efficacy.Methods:128 patients with SAP diagnosed admitted to the First Hospital Affiliated to Hebei North College from March 2019 to December 2021 were enrolled and given Ulinastatin combined with continuous blood purification therapy. The levels of C-reactive protein (CRP), procalcitonin (PCT), interleukins (IL-6, IL-8), tumor necrosis factor-α (TNF-α), and D-dimer were measured before and on the third day of treatment. An abdominal CT was performed on the third day of treatment to assess the modified CT severity index (MCTSI) and extra-pancreatic inflammatory CT score (EPIC). Patients were divided into the survival group ( n = 94) and the death group ( n = 34) according to the 28-day survival prognosis after admission. The risk factors for the SAP prognosis were analyzed using Logistic regression, which was then used to build nomogram regression models. The value of the model was evaluated using the concordance index (C-index), calibration curves and decision curve analysis (DCA). Results:Before treatment, the levels of CRP, PCT, IL-6, IL-8 and D-dimer in the death group were higher than those in the survival group. After treatment, the levels of IL-6, IL-8 and TNF-α in the death group were higher than those in the survival group. MCTSI and EPIC scores in the survival group were lower than those in the death group. Logistic regression analysis shows that, pre-treatment CRP > 140.70 mg/L, D-dimer > 2.00 mg/L, and post-treatment IL-6 > 31.28 ng/L, IL-8 > 31.04 ng/L, TNF-α > 31.04 ng/L, and MCTSI > 8 points were all independent risk factors for SAP prognosis [odds ratios ( OR) and 95% confidence intervals (95% CI) were 8.939 (1.792-44.575), 6.369 (1.368-29.640), 8.546 (1.664-43.896), 5.239 (1.108-24.769), 4.808 (1.126-20.525), 18.569 (3.931-87.725), all P < 0.05]. Model 1 (consisting of pre-treatment CRP, D-dimer, and post-treatment IL-6, IL-8 and TNF-α) had a lower C-index than that model 2 (consisting of pre-treatment CRP, D-dimer, and post-treatment IL-6, IL-8 and TNF-α, and MCTSI; 0.988 vs. 0.995). The mean absolute error (MAE) and mean square error (MSE) of model 1 (0.034, 0.003) were higher than those of model 2 (0.017, 0.001). When the threshold probability was in the range of 0-0.66 or 0.72-1.00, the net benefit of model 1 was lower than that of model 2. When the threshold probability was in the range of 0.66-0.72, the net benefit of model 1 was higher than that of model 2. In addition, model 2 had a higher C-index than acute physiology and chronic health evaluationⅡ (APACHE Ⅱ) and bedside index of acute pancreatitis severity (BISAP, 0.995 vs. 0.833, 0.751). Model 2 had a lower MAE (0.017) and MSE (0.001) than APACHEⅡ (0.041, 0.002). Model 2 had a lower MAE than BISAP (0.025). Model 2 had a higher net benefit than both APACHEⅡ and BISAP. Conclusion:The prognostic assessment model of SAP consisting of pre-treatment CRP, D-dimer, and post-treatment IL-6, IL-8 and TNF-α, and MCTSI has high discrimination, precision and clinical application value, and is superior to APACHEⅡ and BISAP.

ABSTRACT

Objective:To establish a risk prediction model dominated by diaphragm thickening fraction (DTF) and intra-abdominal pressure (IAP) monitoring, and to explore the predictive value of the model for weaning failure in patients with severe acute pancreatitis (SAP).Methods:A prospective research was conducted. Sixty-three patients undergoing invasive mechanical ventilation treatment who diagnosed with SAP admitted to intensive care unit of the First Affiliated Hospital of Jinzhou Medical University from August 2020 to October 2021 were enrolled. The spontaneous breathing trial (SBT) was carried out when the clinical weaning criteria was met. The stable cardiovascular status, good pulmonary function, no chest and abdominal contradictory movement, and adequate oxygenation were defined as successful weaning. Otherwise, it was defined as failure weaning. The clinical indicators such as SBT 30-minure DTF, IAP, tidal volume (VT), respiratory rate (RR), body mass index (BMI), and blood lactic acid (Lac) were compared between the weaning success group and the weaning failure group. The indicators with statistically significant differences in the single-factor analysis were included in the secondary multivariable Logistic regression analysis to establish a risk prediction model. The correlation between the DTF and IAP at 30 minutes of SBT was analyzed. Receiver operator characteristic curve (ROC curve) was drawn to analyze the predictive value of the risk prediction model for SAP patient withdrawal failure at 30 minutes of SBT.Results:Finally, 63 patients with SAP were enrolled. Among the 63 patients, 42 were successfully weaned and 21 failed. There were no significant differences in age, gender, and oxygenation index (PaO 2/FiO 2), sequential organ failure assessment (SOFA) score, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score at admission between the two groups, indicating that the data in the two groups were comparable. Compared with the weaning success group, IAP, RR, BMI and Lac at 30 minutes of SBT in the weaning failure group were significantly increased [IAP (mmHg, 1 mmHg≈0.133 kPa): 14.05±3.79 vs. 12.12±3.36, RR (times/min): 25.43±8.10 vs. 22.02±5.05, BMI (kg/m 2): 23.71±2.80 vs. 21.74±3.79, Lac (mmol/L): 5.27±1.69 vs. 4.55±1.09, all P < 0.05], while DTF and VT were significantly decreased [DTF: (29.76±3.45)% vs. (31.86±3.67)%, VT (mL): 379.00±98.74 vs. 413.60±33.68, both P < 0.05]. Secondary multivariable Logistic regression analysis showed that DTF [odds ratio ( OR) = 0.758, 95% confidence interval (95% CI) was 0.584-0.983, P = 0.037], IAP ( OR = 1.276, 95% CI was 1.025-1.582, P = 0.029), and RR ( OR = 1.145, 95% CI was 1.014-1.294, P = 0.029) were independent risk factors for SBT withdrawal failure in 30 minutes in SAP patients. The above risk factors were used to establish the risk prediction model of aircraft withdrawal failure at 30 minutes of SBT: Logit P = -0.237-0.277×DTF+0.242×IAP+0.136×RR. Pearson correlation analysis showed that SBT 30-minute DTF was significantly correlated with IAP in SAP patients, and showed a significant positive correlation ( r = 0.313, P = 0.012). The ROC curve analysis results showed that area under the ROC curve (AUC) of the risk prediction model for SAP patient withdrawal failure at 30 minutes of SBT was 0.716, 95% CI was 0.559-0.873, P = 0.003, with the sensitivity of 85.7% and the specificity of 78.6%. Conclusions:DTF, IAP and RR were independent risk factors for SBT withdrawal failure in 30 minutes in SAP patients. The DTF and IAP monitoring-oriented risk prediction model based on the above three variables has a good predictive value for weaning failure in patients with SAP.

ABSTRACT

OBJECTIVE To compare the efficacy of different enteral nutrition (EN) drugs for severe acute pancreatitis (SAP) and their gastrointestinal tolerance. METHODS A total of 118 SAP patients admitted to the Pancreatic Center of Jiangsu Provincial People’s Hospital from January 1, 2022 to June 30, 2023 were collected and divided into short-peptide EN drugs (SP) group (41 cases), dietary fiber-free intact protein EN drugs (TP-MCT) group (40 cases) and dietary fiber-containing intact protein EN drugs (TPF-DM) group (37 cases) according to the types of EN. All three groups of patients were given continuous pumps of EN drugs via nasal feeding for 24 hours, with a target energy dose of 25-30 kcal/kg. The blood nutritional indexes [albumin (ALB), total protein (TP), hemoglobin (Hb), globulin (GLB)], inflammation indexes [white blood cells (WBC), percentage of neutrophils (N%), procalcitonin (PCT), C-reactive protein (CRP), interleukin-6 (IL-6)], clinical outcomes indexes [time of stay in the intensive care unit (ICU), length of hospital stay, duration of resuming oral diet, the rate of cases without improvement, mortality rate] and the occurrence of gastrointestinal tolerance were collected from 3 groups before medication and 7 d after medication. RESULTS After treatment, ALB and TP in 3 groups were significantly higher than before treatment (P<0.05); CRP and N% of 3 groups, PCT of TP-MCT group and IL-6 of SP group were significantly lower than corresponding group before medication (P< 0.05); PCT of TP-MCT group and IL-6 of SP group were significantly lower than those of other two groups at corresponding period (P<0.05). There were no statistical significances in ALB, TP, CRP or N% among the three groups after medication, and in Hb, GLB or WBC among the three groups before and after treatment (P>0.05). There was no significant difference in clinical outcome indexes among 3 groups (P>0.05). The incidence of gastrointestinal adverse reactions in the TP-MCT group was the lowest (32.50%), and significantly lower than those in the SP group (46.34%) and TPF-DM group (48.65%) (P<0.05). CONCLUSIONS Different EN preparations can improve the nutritional status and reduce the inflammatory response in SAP patients to different extents, among which SP and TP-MCT are more effective, and TP-MCT shows the better gastrointestinal tolerance.

ABSTRACT

Objective:To study the clinical characteristics and risk factors for hypertriglyceridemia-induced severe acute pancreatitis (HTG-SAP) complicated by acute kidney injury.Methods:The clinical data of HTG-SAP patients admitted to the Department of Critical Care Medicine of the Second Affiliated Hospital of Anhui Medical University from January 2014 to July 2022 were retrospectively collected, and divided into an AKI group and a non-AKI group according to whether AKI occurred. The general condition, laboratory data and clinical characteristics of the two groups were compared. Factors with statistically significant differences were screened for logistic regression analysis and a predictive model was constructed. We plotted the receiver operating characteristic curve and used the area under the curve (AUC) to evaluate the predictive ability of each predictor for HTG-SAP complicated with AKI.Results:A total of 91 patients were included, including 37 (40.7%) with AKI and 54 (59.3%) without AKI. The proportions of extrapancreatic infection, sepsis and multiple organ dysfunction syndrome, requiring mechanical ventilation, continuous renal replacement therapy (CRRT), retroperitoneal puncture, and surgical intervention were higher in the AKI group than in the non-AKI group (all P<0.05). The length of ICU stay, total length of hospitalization, and mortality rate in the AKI group were higher than those in the non-AKI group (all P<0.05). Multivariate logistic regression analysis showed that acute physiology and chronic health status scoreⅡ (APACHEⅡ) ( OR=2.069, 95% CI: 1.286-3.417, P=0.003), abdominal pressure ( OR=1.469, 95% CI: 1.108-1.958, P=0.007), and lactic acid ( OR=3.156, 95% CI: 1.013-9.831, P=0.047) were independent risk factors for AKI in HTG-SAP patients. The AUCs of the APACHEⅡ score, abdominal pressure, lactic acid level and combined prediction model were 0.951, 0.918, 0.837 and 0.986, respectively. Conclusions:Patients with HTG-SAP complicated with AKI were more likely to have complications related to extrapancreatic infection, sepsis and multiple organ dysfunction, and the proportion of mechanical ventilation, CRRT, retroperitoneal puncture and surgical intervention required during hospitalization was greater, the lengths of ICU stay and total hospital stay were longer, and the mortality rate was higher. APACHEⅡ score, abdominal pressure and lactic acid were independent risk factors for HTG-SAP concurrent AKI, and the prediction model established based on these three factors had higher value in predicting HGT-SAP concurrent AKI

ABSTRACT

Objective:To establish and validate a nomogram model for early prediction of the risk of acute pancreatitis (AP) progressing to severe acute pancreatitis (SAP).Methods:CT signs and clinical laboratory parameters of 361 AP patients admitted to our Hospital from January 2016 to July 2022 were retrospectively collected. There were 221 males (61.2%) and 140 females (38.8%). According to the Atlantic score, all patients were divided into the SAP group (64 cases) and the non-SAP (NSAP) group (297 cases). Univariate analysis was used to screen out variables with statistically significant differences. Multivariate Logistic regression analysis was used to screen out the independent risk factors of SAP, and finally a nomogram prediction model was established. Receiver operating characteristic (ROC) curve, calibration curve and decision curve (DCA) were used to evaluate the predictive efficacy, accuracy and clinical practicability of the model, and Bootstrap method was used to verify the model internally.Results:Univariate analysis and multivariate Logistic regression analysis showed that pleural effusion ( OR=7.353, 95% CI: 3.344-16.170), posterior pararenal space (PPS) involvement ( OR=3.149, 95% CI: 1.314-7.527), serum creatinine concentration (Cr) ( OR=1.027, 95% CI: 1.017-1.038) and serum calcium concentration (Ca 2+) ( OR=0.038, 95% CI: 0.009-0.166) were independent risk factors for SAP ( P<0.05). A Nomogram model was established based on these four factors. The area under the ROC curve (AUC) of this model was 0.905 (95% CI: 0.869-0.933), indicating high predictive efficiency. Internal verification showed that the model had good accuracy in predicting SAP, and C-index was 0.90. DCA analysis showed that the model had high clinical practicability. Conclusions:The Nomogram model combining pleural effusion, PPS involvement, Cr and Ca 2+ had a good effect on early prediction of SAP, which could provide a new reference tool for clinical diagnosis and treatment.

ABSTRACT

Objective:To analyze the predictive value of serological measures within 24 hours of admission in acute pancreatitis patients against patients with severe acute pancreatitis(SAP), because the severity of acute pancreatitis was characterized by a timely assessment and prediction by emergency department physicians upon visit.Methods:A total of 119 acute pancreatitis patients admitted in Emergency Department in Beijing Jishuitan Hospital, Capital Medical University from January 2022 to December 2022 were retrospectively collected. According to the revised Atlanta classification, patients were characterized by mild acute pancreatitis group (77 cases), moderately severe acute pancreatitis group (27 cases), and SAP group (15 cases). Basic characteristics, early disease severity scores and early serological indexes of the three groups were compared, independent risk factors of serological indexes affecting the occurrence of SAP were analyzed, and receiver operator characteristic curve was drawn, evaluate the predictive value of related serological indexes for SAP.Results:There were no significant differences in the basic characteristics of the three groups including of gender, age, BMI, type of pancreatitis and complications ( P>0.05), but there were significant differences in early BISPA, Ranson, APACHEⅡ and Panc3 scores among the three groups ( P<0.05).Albumin-bilirubin score ( OR=3.653, 95% CI 1.665-8.012, P=0.001), blood urea nitrogen ( OR=1.117, 95% CI 1.039-1.202, P=0.003) were independent risk factors for SAP. The areas under ROC curve predicted by albumin-bilirubin score, blood urea nitrogen and albumin-bilirubin score combined with blood urea nitrogen were 0.762, 0.776 and 0.857, respectively, which showed no statistical difference compared with earlier Ranson, BISAP and APACHE Ⅱ scoring systems, respectively ( P>0.05). Conclusions:Early albumin-bilirubin score and blood urea nitrogen indexes of acute pancreatitis patients have good predictive value for SAP. Albumin-bilirubin score combined with blood urea nitrogen can improve the predictive value of SAP, and the predictive effect is as good as early Ranson, BISAP and APACHEⅡ scoring systems.

ABSTRACT

Objective:To analyze the effect and clinical significance of continuous renal replacement therapy (CRRT) on severe acute pancreatitis complicated with different grades of intra-abdominal hypertension, and to determine whether the level of intra-abdominal pressure can be used as one of the indicators of CRRT in these patients.Methods:From September 2020 to September 2022, the clinical data of 66 patients with severe acute pancreatitis complicated by intra-abdominal pressure (IAP) ≥12 mmHg who were treated with CRRT and admitted to the EICU of Affiliated Hospital of Xuzhou Medical University were retrospectively analyzed. According to the level of IAP, they were divided into group A: 12 mmHg≤IAP < 15 mmHg, 22 cases; group B: 15 mmHg≤IAP≤20 mmHg, 23 cases and group C: IA P>20 mmHg, 21 cases. The general clinical data and IAP values before and after CRRT treatment, as well as the ΔIAP (difference of IAP before and after treatment) were recorded. The difference of IAP before and after treatment and the ΔIAP between group B and group C were compared by independent sample t test. The relationship between IAP before treatment and ?IAP was analyzed by spearman test. Results:There were no significant differences in gender, age, modified Marshall score, APACHE Ⅱ score, number of mechanical ventilation, and etiology among the three groups before treatment( P>0.05). After CRRT treatment, IAP of group A was no significantly changed before and after treatment ( P>0.05). IAP in groups B and C was significantly lower after treatment than before treatment ( P<0.05), and the ΔIAP of group C was significantly higher than that of group B ( P<0.05). There was a positive correlation between IAP before treatment and ?IAP in group B and Group C ( P<0.05). Conclusions:1.For patients with severe pancreatitis complicated with intra-abdominal hypertension, CRRT treatment can effectively reduce IAP when IAP≥15 mmHg, and the higher the IAP, the more obvious effect of CRRT treatment in controlling intra-abdominal pressure. 2. IAP≥15 mmHg can be used as one of the indicators for CRRT in SAP patients.

ABSTRACT

This study was designed to investigate the effect of emodin(EMO)on endoplasmic reticulum stress(ERS)in alveolar macrophages(AMs)of rats with severe acute pancreatitis(SAP)and the underlying mechanism.Forty rats were recruited and randomized into four groups:sham-operation(SO)group,SAP group,4-phenylbutyric acid(4-PBA)group and EMO group.The SAP model was established by retrograde injection of 5%sodium taurocholate into the biliopancreatic duct.HE staining was performed to observe the pathological changes in the pancreas and lung;the wet/dry weight ratio of lung tissue was calculated.Arterial partial pressure of the oxygen(PaO2)and carbon dioxide(PaCO2)were measured;the serum amylase activity and the levels of inflammatory factors TNF-α and IL-6 were evaluated.TUNEL staining was used to determine the cell apoptosis rate of lung tissue;Western blot was used to detect the protein expression levels of GRP78,ATF6,CHOP,and Caspase-12.Moreover,rat AMs(NR8383)were signed into control(CON)group,lipopolysaccharide(LPS)group,4-phenylbutyric acid(4-PBA)group and EMO group in vitro.Glutathione(GSH)and malondialdehyde(MDA)levels in the cell medium were measured,as were the protein expression levels of GRP78,ATF6,CHOP,and Caspase-12 in AMs.For experiments in vivo,compared with the SO group,the pathological score of pancreatic and lung in SAP rats was increased(P<0.05),the levels of serum amylase activity,IL-6 and TNF-α were increased(P<0.05),the wet/dry weight ratio and apoptosis rate of lung tissue were increased(P<0.05),PaO2 was decreased,PaCO2 was increased(P<0.05),and the protein expression of GRP78,ATF6,CHOP and Caspase-12 were increased in lung tissue(P<0.05).Compared with the SAP group,these indexes mentioned above in the 4-PBA and EMO groups were reversed(P<0.05).For experiments in vitro,compared with the CON group,GSH levels were decreased,and MDA levels were increased in the cell medium of LPS group(P<0.05),and the expression of GRP78,ATF6,CHOP and Caspase-12 proteins were upregulated(P<0.05).Compared with the LPS group,these indexes mentioned above in in cell medium of the 4-PBA and EMO groups were reversed(P<0.05).In conclusion,the protective effect of EMO on pancreatic and lung injury in SAP rats may be closely related to the inhibition of ATF6/CHOP pathway-induced inflammation and oxidative stress in AMs.

ABSTRACT

Objective:To investigate the efficacy of neostigmine combined with raw rhubarb enema on severe acute pancreatitis (SAP) patients with intra-abdominal hypertension (IAH).Methods:The clinical data of 89 SAP patients, who were admitted and underwent continuous renal replacement treatment (CRRT) in intensive care unit (ICU) department of the First Affiliated Hospital of Hebei North University from January 2018 to June 2022, were retrospectively analyzed. Patients were divided into control group ( n=44) and experimental group ( n=45) according to the treatment mode. Raw rhubarb enema plus sodium sulfate topical application were administrated twice a day for 7 days in control group; besides the treatment above, intramuscular injection of neostigmine 0.5 mg twice a day for 7 days was given in experimental group. Intra-abdominal pressure was monitored, acute physiology and chronic health evaluation (APACHE)Ⅱ, kidney disease: improving global outcome stage (KDIGO), lung injury score (LIS) were recorded, and serum leukocyte, CRP, procalcitonin (PCT), IL-6, IL-8 and tumor necrosis factor (TNF)-ɑ level were examined before and after treatment in both groups. The primary endpoint was the amount change of intra-abdominal pressure within 24 hours, and secondary endpoints included increased fecal volume within 7 days after treatment, new abdominal compartment syndrome (ACS), new organ dysfunction, vascular complications, length of ICU stay, total length of stay, survival rate and treatment intervention and occurrence of complications within 6 months after the end of treatment. Results:Intra-abdominal pressure began to decrease at 9 hours after treatment both in control group and experimental group. Compared with that before treatment, the intra-abdominal pressure of the two groups decreased significantly after 7 days of treatment, and the decrease rate of the experimental group within 7 days was obviously higher than that of the control group, with statistical significance (all P values <0.05). Compared with those before treatment, APACHEⅡ, KDIGO and LIS in both groups were significantly decreased, but the decreases in experimental group were more remarkable than those in control group (all P values <0.05). After treatment, the serum WBC count and the levels of inflammatory factors CRP, PCT, IL-6, IL-8, TNF-ɑ in experimental group were obviously lower than those in control group with statistical significance (all P values <0.05). Compared with control group, the change of intra-abdominal pressure in experimental group was significantly increased after 24-hour treatment, and the fecal volume was also obviously increased on day 1, 2, 3, 5 and 7 after treatment (all P values <0.05). However, there were no significantly statistical differences on the severity of intra-abdominal pressure, new occurrence of ACS and organ failure, vascular complication, ICU hospitalization and total length of stay and survival rate between two groups. After 6-month follow-up, the recurrence of pancreatitis and its treatment intervention between two groups were not statistically significant. Conclusions:The adjuvant treatment of neostigmine could reduce intra-abdominal pressure, increase defecation volume in SAP patients and alleviate SAP condition, which might be related to reducing the release of inflammatory cytokines.

ABSTRACT

Objective:To evaluate the clinical efficacy of TCM Qingjie Huagong Decoction combined with routine internal medicine in the treatment of severe acute pancreatitis with cholelithiasis (bile duct stones) in the early stage.Methods:Thirty-two patients with severe acute pancreatitis combined with cholelithiasis in the first affiliated Hospital of GuangXi University of Traditional Chinese Medicine were selected and randomly divided into two groups with 16 in each, both groups were treated for 14 days. Serum amylase (AMS) was detected by iodine-starch colorimetry, GOT and GPT were detected by continuous monitoring method, and CRP, IL-6 and procalcitonin (PCT) were detected by immune transmission turbidimetry. Acute Physiological and Chronic Health Score Ⅱ (APACHE Ⅱ), CT Severity Index Score (CTSI) and Modified Marshall Score were used to evaluate the severity of SAP. The recovery time of body temperature, the relief time of abdominal distension pain, the recovery time of bowel sounds and the total hospital stay were observed and recorded to evaluate the clinical effect.Results:The total effective rate was 93.8% (15/16) in the treatment group and 75.0% (12/16) in the control group. There was significant difference between the two groups ( χ2=8.19, P=0.042). After treatment, the level of AMS, WBC, CRP, PCT, AST, ALT and IL-6 in the treatment group were lower than those in the control group ( t values were 14.3, 7.24, 9.63, 5.48, 7.05, 7.33, 28.34, respectively, all Ps<0.05); After treatment, the time for body temperature to return to normal [(2.91±0.12)d vs. (3.78±0.38)d, t=8.76], the time for relief of abdominal distension pain [(4.77±0.68)d vs. (7.13±1.55)d, t=9.52], the time for recovery of bowel sounds [(3.90±1.80)d vs. (4.89±1.38)d, t=2.98] and the total hospital stay [(22.60±2.80)d vs. (30.37±3.89)d, t=7.88] in the treatment group were all significantly shorter than those in the control group ( P<0.01); APACHE Ⅱ, CTSI and the Modified Marshall Score in the treatment group were lower than those in the control group ( t values were 11.82, 12.72, 7.71, respectively, all Ps<0.01). Conclusion:Qingjie Huagong Decoction combined with ERCP and conventional western medicine therapy can reduce the level of inflammation in patients with cholelithiasis in the early stage of SAP, relieve clinical symptoms and improve clinical efficacy.

ABSTRACT

Objective:To investigate the early evaluation potential of serum levels of apolipoprotein B/apolipoprotein A1 (Apo B/A1), microtubule-associated protein 1-light chain 3 (MAP1-LC3) and intercellular adhesion molecule-1 (ICAM-1) in acute pancreatitis (AP) patients.Methods:A total of 413 AP patients who were treated at the Second Affiliated Hospital of Anhui Medical University between January 2019 and August 2020 were enrolled. Serum samples were collected from AP patients within 24 h of admission. Patients were divided into the non-severe acute pancreatitis (Non-SAP, n=315) and severe acute pancreatitis (SAP, n=98) groups according to the severity of the disease. Sixty healthy controls were recruited. The differences of serum Apo B/A1, MAP1-LC3 and ICAM-1 among the three groups were compared by one-way analysis of variance, and the correlation between Apo B/A1, MAP1-LC3 and ICAM-1 and the severity of AP was analyzed by Pearson correlation analysis. Sensitivity and specificity in assessing AP severity were predicted by receiver operating characteristic curve (ROC). Results:The early levels of Apo B/A1, MAP1-LC3 and ICAM-1 were all significantly higher for AP patients than for healthy controls ( P<0.05), and the levels of Apo B/A1, MAP1-LC3 and ICAM-1 in SAP patients were significantly higher than those in non-SAP patients[Apo B/A1: 2.21±1.40 vs. (0.96±0.34); MAP1-LC3: 0.92±0.29 vs. (0.48±0.24) ng/mL and ICAM-1: (235.57±54.50 ) vs. (120.28±61.69)ng/mL; P<0.05]. Pearson correlation analysis showed that levels of Apo B/A1, MAP1-LC3 and ICAM-1 were positively correlated with the first Ranson score after admission ( P<0.05), and ICAM-1 showed the highest degree of correlation with AP severity ( r=0.519). Areas under the receiver operating characteristic curve (AUROC) were 0.769 for Apo B/A1, 0.811 for MAP1-LC3, 0.828 for ICAM-1, and 0.938 for combined detection. Conclusions:Serum levels of Apo B/A1, MAP1-LC3 and ICAM-1 within 24 h after admission are significantly correlated with the severity of AP, which has clinical significance for early prediction of the severity of AP.
