OBJECTIVETo investigate the feasibility and features of 3 catheter-mediated approaches of gene transfer into heart, including direct myocardial injection (DMI), coronary artery perfusion (CAP), and intrapericardial cavity injection (ICI).

METHODSFifteen dogs were used, and 0.3 ml (1 x 10(9) pfu) of an adenovirus (Adex1SR LacZ) was injected into the heart by 3 methods. The dogs were killed 5 days following injection, and gene expressions in heart and liver were evaluated by histochemical analysis.

RESULTSThe results showed that (1) the CAP method was relatively less damaging and induced sparse LacZ expression in the myocardium, and the gene expression was also found in both vessels within the myocardium and liver; (2) gene transfer by DMI resulted in intense LacZ expression around the injection accompanied by a local inflammatory response; (3) LacZ expression elicited by ICI was detected in either the inner surface of the parietal pericardium or epicardial surface of the heart, and also in the myocardium underlying the visceral pericardium.

CONCLUSIONThree catheter-mediated methods of gene transfer into the heart may be used and a reasonable approach should be chosen according to purpose.

AIM: To establish an animal model of experimental autoimmune myocarditis (EAM) in BALB/c mice and to investigate the expression and significance of Toll-like receptor 3 in mouse EAM. METHODS: BALB/c mice were immunized with cardiac myosin extracted from porcine ventricular myocardium covered by complete freund's adjuvant (CFA) on 0 d and 7 d, then divided into immunized with CFA only. Serum and myocardium samples were collected at 14 d and 21 d after the first immunization. HE staining was used to identify the areas of inflammation. The myosin IgG antibody was examined by indirect ELISA assay. The changes of TLR3 protein and mRNA expression in myocardial tissue were measured by immunohistochemistry and real time-PCR. RESULTS: Compared to control group, immunohistochemistry results showed that there was positive expression of TLR3 in the myocardium of mice with EAM and the mRNA of TLR3 were more than 20 times (P<0.05). The expression of interferon beta mRNA in EAM group was more than 14 times as many as basal expression, that of tumor necrosis factor alpha was more than 18 times (P<0.05). CONCLUSION: The expression of Toll-like receptor 3 in myocardium is up-regulated in experimental autoimmune myocarditis. The inflammatory response to cardiac myosin may associate with the TLR3 signal transduction pathway.

Objective:To explore the influence of the timing of the drainage tube removal on the clinical pathway after radical resection of papillary thyroid carcinoma.Methods:The clinical data of 64 patients with radical resection of papillary thyroid carcinoma discharged to the department of general surgery, First Affiliated Hospital of Anhui University of Science and Technology from December 2019 to May 2020 were retrospectively analyzed. There were 14 males and 50 females, aged (45.8 ± 11.7) years and ranging from 23 to 73 years. According to the amount of postoperative drainage fluid, decide whether to extubate and divide the patient into a study group and a control group, there were 37 cases in the study group and 27 cases in the control group. The extubation indication in the study group was 24 hours of drainage fluid volume <20 mL, the control group was 24 hours of drainage fluid volume <10 mL. The differences in operation time, intraoperative blood loss, tumor diameter, number of lymph node dissection, extubation time, postoperative complications, hospitalization cost, postoperative hospitalization time, total hospitalization time, and clinical path completion rate were compared between the two groups. The measurement data of normal distribution were expressed as mean±standard deviation ( Mean± SD), and the t test was used for comparison between groups, the measurement data of non-normal distribution were measured by M ( P25, P75), and the Mann-Whitney U test were used for comparison between groups.Counting data were expressed as percentages(%), and chi-square test was used in comparison between groups. Results:There were no significant difference between the two groups in the operation time, total intraoperative blood loss, tumor diameter, number of lymph node dissections, postoperative complications and hospitalization costs( P>0.05). The extubation time, postoperative hospitalization time, hospitalization time and clinical path completion rate of the study group were 2.9(2.5, 3.5) d、3.0(3.0, 3.5) d、7.0(7.0, 8.5) d and 70.3% (26/37), vespectively. In the control group, they were 4.5(3.8, 5.5) d、5.0(4.0, 6.0) d、11.0(10.0, 13.0) d and 11.1% (3/27), respectively. The difference between the two groups were statistically significant ( P<0.05). Conclusion:After radical resection of papillary thyroid cancer, taking the 24 h drainage volume <20 mL as the timing of extubation does not increase the incidence of postoperative complications, which can significantly shorten the extubation time, postoperative hospitalization time and total hospitalization time and improve clinical path completion rate.

Objective:To explore the safety of clinical application of liver cysts under the mode of ambulatory surgery.Methods:Retrospective analysis of the data of 84 patients with liver cysts admitted to the Huainan First People′s Hospital, the Fourth Affiliated Hospital of Bengbu Medical College from January 2017 to December 2019, they were divided into study group ( n=42) and control group according to the random number table method ( n=42). The control group adopted the traditional perioperative management method, and the research group adopted the day surgery treatment mode. The two groups of patients were evaluated for their hospitalization days, total cost, satisfaction, activity of daily living (ADL) score of 7 days after surgery, temporary cancellation rate, unplanned readmission rate, total postoperative complications and other indicators. Normally distributed measurement data were expressed as mean±standard deviation ( Mean± SD), and independent sample t test was used for comparison between groups.

The control group were (5.33±1.69) d and (0.90±0.22) ten thousand yuan, respectively. The study group was lesser than In the control group, the differences between the two groups were statistically significant ( P<0.001). The patient satisfaction score of the study group was (4.20±0.64) points, and the control group was (3.20±0.92) points. The study group was higher than the control group. The difference between the two groups was statistically significant ( P<0.001). The postoperative ADL score, temporary cancellation rate, unplanned readmission rate, and total postoperative complication rate in the study group were (46.45±9.75) points, 4.76%, 7.14% and 9.52%, respectively. The control group were (45.57±7.02) points, 2.38%, 4.76% and 7.14%, there was no significant difference between the two groups ( P>0.05). Conclusions:Ambulatory laparoscopic fenestration of liver cysts is safe and effective for the treatment of patients with liver cysts. Compared with traditional in-patient surgery, it can reduce the length of stay and the cost of hospitalization and increase the satisfaction of patients.

Objective:To study the factors influencing repeatedly hospitalization in patients with acute pancreatitis (AP), and to analyse the predictive value of triglyceride for repeated hospitalization.Methods:The clinical data of 1 958 patients with AP treated at the First Affiliated Hospital of Anhui University of Science and Technology from January 2012 to April 2022 were analyzed. Of 1 733 AP patients who were enrolled, there were 1 000 males and 733 females, with mean ± s. d age being (49.4±16.4) years. Patients were grouped based on their ID numbers to determine their number(s) of hospitalization. Those who were admitted only once were included in the initial hospitalization group ( n=1 030), and those who were admitted twice or more were included in the repeated hospitalization group ( n=703). The factors influencing repeated hospitalization were analyzed by univariate analysis and multivariate logistic regression analysis. The predictive value of triglyceride for repeated hospitalization was evaluated by receiver operating characteristic (ROC) curve. Results:Multivariate logistic regression analysis showed that hypertriglyceridemia ( OR=1.445, 95% CI: 1.144-1.825, P=0.002) and biliary causes ( OR=3.184, 95% CI: 1.978-5.125, P<0.001) were independent risk factors for repeated hospitalization. When triglyceride <10.9 mmol/L, the prediction of AP patients without repeated hospitalization was 90.6%. The area under the ROC curve was 0.589, and the Yoden index was 0.170. Conclusion:Hypertriglyceridemia was risk factor for repeat hospitalization in AP patients and the efficacy of triglyceride in predicting repeat hospitalization in AP patients was good.

Objective To investigate the values of systemic inflammatory response index(SIRI),systemic immunoinflammatory index(SII),neutrophil count/lymphocyte count(NLR),platelet count/lymphocyte count(PLR)and lymphocyte count/monocyte count(LMR)in prediction of the severity of acute pancreatitis(AP)at early stage.Methods The clinical data on 666 AP patients admitted to the department of hepatobiliary surgery,the First Affiliated Hospital of Anhui University of Science and Technology,from January 2020 to November 2023 were retrospectively analyzed.The patients were divided into a mild group(MAP group,mild acute pancreatitis)and a non-mild group(non-MAP group,including moderate to severe acute pancreatitis).Blood routine and biochemical indicators were collected at admission and 24 hours after admission.The differences in SIRI,SII,NLR,PLR and LMR between the two groups were compared,so were the values of these five indexes in prediction of non-MAP.Results Of the 666 AP patients,507 were in the MAP group and 159 in the non-MAP group.In the non-MAP group,C-reactive protein(CRP),SIRI,SII,and NLR were higher than those in the MAP group 24 hours after admission,while LMR was lower than that in the MAP group,and the differences were statistically significant(P<0.05).CRP(HR=1.008,95%CI:1.004～1.012,P<0.05)and SIRI(HR=1.216,95%CI:1.029～1.436,P<0.05)were identified as the risk factors for the severity of AP.The ROC curve showed that the AUC and sensitivity of SIRI for predicting non-MAP 24 hours after admission were 0.718 and 75.00%,respectively,higher than those of SII,CRP,NLR,and LMR.Both SIRI and CRP had AUC values greater than 0.7,and the combined AUC was 0.788(0.738～0.837),the sensitivity was 86.00%and the specificity was 81.44%.Conclusions SIRI can be used as a predictor of disease severity in early AP patients,and combined with CRP can improve the predictive value.
