Objective To evaluate the efficacy and safety of domperidone combined with flupentix-ol,melitracen ( deanxit ) and alprazolam in the treatment of functional dyspepsia .Methods One hundred and sixty patients with functional dyspepsia were randomly divided into the treatment group ( n =80 ) and the control group ( n =80 ) .The treatment group was given domperidone combined with flupentixol , meli-
tracen (deanxit) and alprazolam, and the control group was only given domperidone for 4 weeks.The im-provement of clinical symptoms such as stomach burn ,early enough, abdominal distension, sour regurgita -tion and eructation were evaluated by clinical symptom score .Results Compared with patients in the con-trol group, the rate of marked improvement and rates of improvement for patients in the treatment group were all better ( P <0.01).Furthermore, the adverse reaction is light .Conclusion The application of domp-eridone combined with flupentixol, melitracen ( deanxit ) and alprazolam is quite effective in treating patients with FD.

Objective To investigate the possible influence of immunosuppressive therapy,including sirolimus (SRL) and calcineurin inhibitors (CNI, tacrolimus), on level of Treg in the liver allo-graft recipients, Methods Forty-seven liver transplant recipients with stable liver function were assessed for at least 2 years, and divided into two groups: one composed of 15 patients receiving SRL,and another, of those receiving CNI (32 patients with tacrolimus). Thirty-eight age-matched healthy subjects (HS) were used as normal controls. We examined the expression of CD4, CD25, and Foxp3 in peripheral blood monouclear cells. Treg of every group was analyzed using Cell Quest software.Results SRL significantly increased the prevalence of CD4+ CD25high T cells, compared with HS and CNI group. The prevalence of CD4+ CD25high T cells of CNIs group was significantly lower than that of HS. The percentage of CD4+ CD25high T cells in the total CD4+ T cells was 1.88 % (1.56 %-2. 60 %), 1. 15 % (0. 57 %-l. 48 %) and 0. 84 % (0. 46 %-1. 45 %) in SRL, NS and CNI group,respectively (P<0. 01 or P<0. 05). Foxp3 was expressed in more than 95 % of CD4 + CD25high T cells and less than 20 % of CD4+ CD25low T cells, whereas not expressed in CD4+ CD25- T cells.Conclusion Different immunosuppressive therapy (SRL or CNI) might have different roles in tolerance induction in liver transplant recipients. Namely, SRL promoted the induction of allo-antigen tolerance, but CNI hampered the progression.

Objective:To explore the clinical features of acute pancreatitis in pregnancy (APIP) and the risk factors for fetal death.Methods:The clinical data of 90 patients with APIP in the Affiliated Hospital of Southwest Medical University were retrospectively analyzed from January 2013 to June 2020. Based on the severity, the patients were classified into MAP groups ( n=41), MSAP groups ( n=33), SAP group ( n=16). According to the presence of fetal deaths, the patients were divided into fetal death group ( n=13) and fetal survival group ( n=77). The clinical characteristics and indicators of patients in each group were compared. Binary logistic regression analysis was performed on the variables with differences between groups to explore independent risk factors for fetal death. The receiver operating characteristic curves of laboratory indicators were drawn to evaluate their diagnostic efficacy. Results:Hyperlipidemia was the main cause in 90 APIP cases (42/90, 46.7%). The levels of LDH, CRP, blood glucose, D2 polymer, albumin and ApoA1, the 1-min and 5-min Apgar scores of neonates were statistically significant among MAP group, MSAP group and SAP group (all P<0.05). There were no maternal deaths in 90 cases and 13 fetal deaths (14.4%). Fetal mortality increased with the severity of APIP. APIP combined with hypertension ( OR=14.742, 95% CI 1.157-187.890, P=0.038), ketoacidosis ( OR=19.587, 95% CI 1.789-214.469, P=0.015) and CRP level ( OR=1.013, 95% CI 1.001-1.025, P=0.031) were risk factors for fetal death. ApoA1 level ( OR=0.118, 95% CI 0.021-0.664, P=0.015) was a protective factor for fetal death. The sensitivity and specificity of ApoA1 for predicting fetal death were 84.6% and 79.2%, the sensitivity and specificity of CRP for predicting fetal death were 76.9% and 84.4%, and the sensitivity and specificity of the combination of the two indicators for predicting fetal death were 100% and 67.5%. Conclusions:The severity of APIP was closely related to fetal death. Hypertension, ketoacidosis and blood level CRP were independent risk factors for fetal death, which should be paid special attention.

ObjectiveTo investigate the clinical features of elderly patients with acute pancreatitis (AP) aged ≥80 years. MethodsA retrospective analysis was performed for 3642 patients with pancreatitis who were admitted to Department of Gastroenterology in The Affiliated Hospital of Southwest Medical University from January 2013 to December 2019, and according to age, they were divided into young group (aged ＜65 years) with 2955 patients, middle-aged group (aged 65-79 years) with 558 patients, and elderly group (aged ≥80 years) with 129 patients. Related clinical data were collected and analyzed, including sex, age, etiology, predisposing factors, past medical history, disease severity, complication, and clinical outcome. The independent samples one-way ANOVA-test was used for comparison of normally distributed continuous data between groups and the least significant difference t-test was used for comparison within each group; the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups; the Kruskal-Wallis H test was used for comparison of ordinal categorical variables. ResultsIn the young group, there were 1721 male patients and 1234 female patients; in the middle-aged group, there were 214 male patients and 334 female patients; in the elderly group, there were 48 male patients and 81 female patients; the middle-aged group and the elderly group had a significantly higher proportion of female patients than the young group (62.8% vs 61.6% vs 41.8%, P＜0.05). High-fat diet was the main predisposing factor for all three groups, and compared with the young group, the elderly group had a significantly lower proportion of patients with AP induced by alcohol or high-fat diet+alcohol (P＜0.05). The elderly group had a significantly higher proportion of patients with the etiology of biliary diseases than the middle-aged group and the young group (798% vs 69.2% vs 41.4%, χ2=204.127, P＜0.05), as well as a significantly lower proportion of patients with the etiology of hyperlipidemia, alcohol, or biliary diseases+hyperlipidemia (all P＜0.05). Among the 129 patients in the elderly group, 83 (64.3%) had mild AP, 23 (17.8%) had moderate-severe AP, and 23 (17.8%) had severe AP; there was a significant difference in the constituent ratio of disease severity between the elderly group and the middle-aged/young groups (H=1972.5, P＜005). The elderly group and the middle-aged group had a significantly lower proportion of patients with recurrence than the young group (both P＜0.05). There were no significant differences in local complications between the three groups (all P＞0.05), and as for systemic complications, compared with the young group, the elderly group had a significantly higher proportion of patients with pneumonia (3.9% vs 2.2%, P＜0.05), acute kidney injury (AKI) (6.2% vs 2.5%, P＜0.05), or multiple organ dysfunction syndrome (MODS) (7.8% vs 4.0%, P＜0.05). Compared with the middle-aged group and the young group, the elderly group had a significantly lower proportion of cured patients (67.4% vs 76.3% vs 820%, P＜0.05) and a significantly higher proportion of patients with improvement (23.3% vs 147%/12.7%, P＜0.05). The elderly group and the middle-aged group had a significantly higher proportion of patients withdrawn from treatment than the young group (8.5%/5.9% vs 3.4%, P＜0.05). There was 1 death in the elderly group (0.8%), 9 deaths in the middle-aged group (1.6%), and 16 deaths in the young group (0.5%), and there was no significant difference between the three groups (P＞0.05). There were no significant differences in length of hospital stay and hospital costs between the three groups (P＞0.05). ConclusionAP patients aged ≥80 years are mainly female and are often caused by biliary factors, and they are likely to develop the complications such as pneumonia, AKI, and MODS.

ObjectiveTo investigate the influence of serum triglyceride (TG) level on the outcome of acute biliary pancreatitis (ABP). MethodsA retrospective analysis was performed for 249 ABP patients who were admitted to The Affiliated Hospital of Southwest Medical University from September 2018 to August 2019, and the patients were divided into normal blood lipid group(n=156) and mild(n=25), moderate(n=44), and severe(n=24) hyperlipidemia groups. The patients’ data were collected for analysis. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups, and the Dunn-Bonferroni test was used for further comparison between two groups. The chi-square test was used for comparison of nominal categorical variables between multiple or two groups; the Kruskal-Wallis H test was used for comparison of ordinal categorical variables between multiple groups, and the Mann-Whitney U rank sum test was used for further comparison between two groups. A multivariate logistic regression analysis was used to investigate the influencing factors for organ failure and infectious pancreatic necrosis (IPN), and the receiver operating characteristic (ROC) curve was used to evaluate the value of different indices in predicting severe acute pancreatitis (SAP). ResultsThere were significant differences in age and BISAP between four groups(χ2=25.057， 10.430, all P＜0.05) . Compared with the normal blood lipid group, the severe hyperlipidemia group had a significantly higher proportion of patients with IPN or multiple organ failure syndrome (MODS) (both P＜0.05), and the moderate hyperlipidemia group had a significantly higher proportion of patients with MODS (P＜0.05), while the severe hyperlipidemia had a significantly higher proportion of patients with systemic inflammation reaction syndrome than the other three groups (all P＜005). Compared with the normal blood lipid group, the moderate and severe hyperlipidemia groups had a significant increase in the risk of MODS (moderate hyperlipidemia group: odds ratio ［OR］=3.500, 95% confidence interval ［CI］: 1.193-10.270, P＜0.05; severe hyperlipidemia group: OR=6.167, 95%CI: 1921-19.792, P＜0.05), and after adjustment, the risk of MODS in the severe hyperlipidemia group was 3.430 times that in the normal blood lipid group (95%CI: 1.198-9.825, P=0.022). The severe hyperlipidemia group had a significant increase in the risk of IPN (OR=4.351, 95%CI: 1.719-11.008, P＜0.05), and after adjustment, the risk of IPN in the severe hyperlipidemia group was 5.819 times that in the normal blood lipid group (95%CI: 1.489-22.745, P＜0.05). Blood lipids had a good value in predicting SAP, with an area under the ROC curve of 0.626 (95%CI: 0.530-0.723, P=0.008). ConclusionCompared with the ABP patients with normal TG, ABP patients with elevated TG tend to have a younger age, more complications, and a higher mortality rate, especially those with a TG level of ＞5.65 mmol/L, and therefore, antihyperlipidemic treatment for such patients should be taken seriously to improve their survival rate and prognosis.

Objective: To compare and analyze patient’s general condition, changes in laboratory parameters, and the spectrum of UGT1A1 mutations in patients with inherited non-hemolytic unconjugated hyperbilirubinemia. Methods: A retrospective study was conducted at Nanjing Second Hospital from January 2015 to July 2018 and patients’ demographic characteristics, liver function test, and UGT1A1 gene were analyzed. The categorical variable data were compared by χ ² test. The normal distribution continuous variable data were compared by t-test and the non-normal distribution continuous variable data were compared using Mann-Whitney U test. Results: Of the 51 patients with inherited non-hemolytic unconjugated hyperbilirubinemia, 44 (86.3%) were Gilbert’s syndrome (GS) and seven (13.7%) were Crigler-Najjar syndrome type II (CNS- II). The male to female ratio was 2.9:1 and the average age was 36.11 ± 13.17 years. Six variant types were detected: C. -40_-39insTA, C. -3279T > G, c.211G > A (p.G71R), c.686C > A (p.P229Q), c.1091C > T (p.P364L), c.1456T > G (P.Y486D). Among them, c.211G > A accounted for 58.82% (30/51), c.-40_-39insTA accounted for 27.5% (14/51), and c.1456T > G accounted for 25.5% (13/51). The total bilirubin(TB) and unconjugated bilirubin (UCB) in CNS-II patients were significantly higher than GS patients[155.91 (130 ~ 207) vs. 38.25(29 ~ 52.15) μmol/L, U = 0, P < 0.01; 144.13 (120.8 ~ 197) vs. 30.00 (21.7 ~ 46.75) μmol/L, U = 0.00, P < 0.01, respectively]. Exon mutations of c.1091C > T and c.1456T > G were statistically significant(P < 0.01).There were no differences in age, TB, UCB, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) between the c.211G > A homozygous variants and heterozygous variants (P > 0.05). Conclusion The common pathogenic mutations of UGT1A1 gene were c.211G > A, c.-40_-39insTA, c.1456T > G. c.211G > A. The mutation has little effect on the level of total bilirubin, but c.1091C > T, c.1456T > G mutations has great influence on the level of total bilirubin.

ObjectiveTo investigate the potential association between early-stage inflammatory response and late-stage infectious pancreatic necrosis (IPN) in patients with acute pancreatitis (AP). MethodsA retrospective analysis was performed for the clinical data of 219 patients with moderate-severe acute pancreatitis (MSAP) and 53 patients with severe acute pancreatitis (SAP) who were admitted to The Affiliated Hospital of Southwest Medical University from June 2019 to June 2020, and according to the presence or absence of systemic inflammatory response syndrome (SIRS) at the initial stage of the disease, they were divided into SIRS group with 160 patients and non-SRIS group with 112 patients. Baseline data, serological markers, complications, and mortality rate were included for analysis. The t-test or the Mann-Whitney U test was used for comparison of continuous data between two groups; the chi-square test was used for comparison of categorical data between multiple groups, and the Bonferroni method was used for further comparison between two groups. A logistic regression analysis was used to screen out valuable variables; the receiver operating characteristic (ROC) curve was used to compare the diagnostic value of variables, and the Z-test was used for pairwise comparison of area under the ROC curve (AUC). ResultsCompared with the non-SIRS group, the SIRS group had significantly higher white blood cell count (WBC), C-reactive protein (CRP), and procalcitonin (all P＜0.05) and a significantly higher proportion of patients with acute peripancreatic necrosis (ANC), IPN, pancreatic necrosis (PN), organ dysfunction, multiple organ dysfunction syndrome (MODS), SAP, critically-ill acute pancreatitis (CAP), death, BISAP score ＞2, CTSI score ＞2,or RANSON score ＞2 (all P＜0.05). The univariate analysis showed that SIRS duration, obesity, CRP, WBC, blood urea nitrogen, PN, ANC, SAP, MODS, RANSON score, BISAP score, and CTSI score were risk factors for IPN in patients with AP (all P＜005), and the multivariate analysis showed that SIRS duration (odds ratio ［OR］=1.307, 95% confidence interval ［CI］: 1.081-1580, P=0006) and ANC (OR=42.247, 95% CI: 10.829-164.818, P＜0.001) were risk factors for IPN; when ANC was excluded, SIRS duration (OR=1.430, 95% CI: 1.207-1.694, P＜0.001) and PN (OR=5.296, 95% CI: 1.845-15.203, P=0.002) were risk factors for IPN. The ROC curve showed that SIRS duration (AUC=0.772, Youden index=0.521), RANSON score (AUC=0701, Youden index=0.319), BISAP score (AUC=0.741, Youden index=0.377), and CTSI score (AUC=0.765, Youden Index=0.414) had a certain value in predicting IPN, and there was no significant difference in AUC between any two indices. The long-duration SIRS group(＞4 d) had a significantly higher proportion of patients with PN, ANC, IPN, SAP, or CAP than the non-SIRS group(0 d), the transient SIRS group(1~2 d), and the persistent SIRS group(3~4 d) (all P＜0.05), and the persistent SIRS group had a significantly higher proportion of patients with SAP than the non-SIRS group (P＜0.05). ConclusionAP patients with SIRS in the early stage are likely to develop organ failure and local complications, and there is a significant increase in the risk of IPN when SIRS duration is ＞4.5 days.

Objective:To explore the independent risk factors for bleeding in patients following percutaneous liver biopsy examination.Methods:The clinicopathological data of patients who underwent percutaneous liver biopsy examination at Nanjing Second Hospital from January 2012 to December 2021 were retrospectively collected. Univariate and multivariate logistic regression analysis were used to investigate the effect of age, gender, lesion type (diffuse liver parenchymal lesions, focal liver lesions), number of biopsies, tissue length, presence or absence of cirrhosis, presence or absence of portosystemic shunt, erythrocytes, white blood cells, hemoglobin, platelets, prothrombin time, fibrinogen, international normalized ratio, and liver biochemical indicators on bleeding following liver biopsy, as well as to screen independent risk factors.Results:A total of 3 331 patients were examined by percutaneous liver biopsy, and 3 060 cases were actually included by excluding 271 cases who took consultation from other hospitals. The overall postoperative hemorrhagic rate was 1.6% (49/3 060). Of which, forty-four cases (1.4%) had overt bleeding (hemodynamic changes or hemoglobin decreased by more than 20 g/L), five cases (0.2%) had minor bleeding, three cases had subcapsular hepatic hemaotma, and two cases had local bleeding from liver biopsy. Among the overt bleeding cases, two cases were in the off-label group (platelet<50×10 9/L or international normalized ratio>1.5), and the rest were in the non-off-label group. The results of univariate analysis showed that factors such as focal liver lesions, portosystemic shunt, prolonged prothrombin time, increased international normalized ratio, bilirubin, and alkaline phosphatase were associated with bleeding after liver biopsy in the non-off-label group. The multivariate collinearity diagnosis revealed statistically significant differences for the indicators. Multivariate logistic regression analysis finally included factors such as lesion type, portosystemic shunt, international normalized ratio, total bilirubin, and alkaline phosphatase. The results showed that patients with focal liver lesions were more prone to bleed after surgery than patients with diffuse liver parenchymal lesions ( OR=3.396, P=0.002, 95% CI: 1.596-7.228). Patients with portosystemic shunt were more prone to bleed than those without portosystemic shunt ( OR=3.301, P=0.018, 95% CI: 1.232-8.845). Patients were more likely to experience bleeding following liver biopsy when their total bilirubin levels were elevated ( OR=1.006, P<0.001, 95% CI:1.003-1.008). Conclusion:Focal liver lesions, portosystemic shunts, and elevated total bilirubin are independent risk factors for bleeding after percutaneous liver biopsy.

For rat spinal magnetic resonance imaging (MRI) experiments, due to the lower main magnetic field strength, shallower detected depth and poor spatial compatibility of the traditional radio frequency (RF) coil, the image signal-to-noise ratio (SNR) of rat spinal was rather lower. In this paper, a RF coil for rat spinal MRI at 9.4 T was developed to improve the image quality and at the same time to avoid the space limitation while scanning in special conditions (cardiac catheterization, etc.). In this article, open birdcage structure was built and magnetic field distribution was calculated. The phantom and rat spine MRI imaging were experimented at 9.4 T to verify the advantage of the coil in rat spine MRI application.

Objective:To examine the overall status of the Jiangsu Province Coronary Artery Bypass Grafting Registry database.Methods:The patients date of Jiangsu Province Coronary Artery Bypass Grafting Registry database from October 2017 to December 2019 was collected retrospectively.Risk factors, history, cardiac function (New York Heart Association class), extent of coronary artery lesion, European system for cardiac operative risk evaluation Ⅱ (EuroSCORE Ⅱ), cardiopulmonary bypss, arterial grafts, the numbers and flow of grafts and postoperative major adverse cardiac and cerebrovascular event(MACCE) information were analyzed. The clinical data of patients underwent on-pump CABG(ONCABG) or off-pump CABG (OPCAB) were compared by t test or χ 2 test. Results:Up till December 2019, the database enrolled 7 138 patients, in which 4 661 patients receiving primary isolated CABG. There were 3 486 males and 1 175 females with the age of (64.6±8.1) years (range:31 to 87 years). There were coronary left main disease in 960 patients, triple vessel disease in 3 934 patients, both left main and triple vessel disease in 837 patients, ejection fraction >50% in 3 841 patients, cardiac function class Ⅲ to Ⅳ in 1 664 patients. EuroSCORE Ⅱ was (2.3±0.7)% (range: 0.5% to 35.8%). There were 2 731 patients (58.59%) underwent ONCABG and 1 930 patients (41.41%) underwent OPCAB. There were 4 144 patients (88.91%) for whom the left internal thoracic artery was harvested. Seven centers (2 centers routinely) used left radial artery, 5 centers (3 centers routinely) used the transit time flow meter. The graft was 3.4±0.7 (range:1 to 7), the aortic crossclamp time was (65.0±20.4) minutes (range: 21 to 196 minutes), the cardiopulmonary bypass time was (90.0±24.2) minutes (range: 33 to 227 minutes). In-hospital death ocurred in 84 patients(1.80%), while re-operation in 93 patients (2.00%), myocardial infarction in 71 patients (1.52%), cerebral infarction in 33 patients (0.71%) and dialysis in 56 patients (1.20%). There were 2 936 patients prescribed with secondary prevention drugs(62.99%).Comparing with OPCAB group, ONCABG group had younger age, more female, more diabetes mellitus, more history of myocardial infarction and percutaneous transluminal coronary angioplasty, poorer cardiac function and coronary lesions, higher EuroSCORE Ⅱ, preoperatively (all P<0.05), and was associated with higher MACCE (135/2 731 vs. 71/1 930, χ 2=4.280, P=0.039), and of more grafts, transfusion and intra-aortic balloon counterpulsation application (all P<0.05). Conclusions:Jiangsu Province Coronary Artery Bypass Grafting Registry database is generally in good operation, and some parameters still need to be improved. Comparing with OPCAB group, ONCABG has more severe preoperative general conditions, while the outcomes is acceptable.
