Objective To discuss feasibility and therapeutic effect of the interventional management through biliary tract drainage with percutaneous transhepatic puncture technique for biliary tract stricture after orthotopic liver transplantation. Methods A retrospective review of the clinical and imaging materials of 292 postoperative orthotopic liver transplantation cases was made. Of these 292 cases, 30 patients suffered from biliary tract complications and treated with billiary balloon dilatation, bile drainage and biliary stenting techniques. Results After biliary balloon dilatation, 3 cases of biliary tract strictures and leaks, 3 cases of simple biliary anastomosis site strictures and 7 out of the 8 cases of multiple biliary tract strictures were cured. In one of the multiple biliary tract stricture patients, a hepatic hematoma after biliary balloon dilatation was found and a second liver transplantation was done. In the 14 cases of multiple biliary tract strictures accompanied with biliary sludge, balloon dilatation technique was repeatedly performed. In 12 of the 14 cases, the strictures were improved remarkably and jaundice was subsided; In one of 14 cases, biliary tract stenting procedure was performed, but liver re-transplatation was carried out because of stent obstruction by much sludge. In the remaining 1 of the 14 cases, because there was no improvement of the strictures and relief of jaundice was revealed after the repeated procedures, liver re-transplantation was finally done In 2 cases of strictures at the opening segment of the T tube, the procedure of percutaneous transhepatic puncture for bile drainage was managed. After the procedure, the strictures were alleviated and the jaundice relieved. Conclusion The interventional managements through percutaneous transhepatic puncture techniques were effective, convenient and minimally invasive for treating biliary tract strictures after orthotopic liver transplantation.

Pain caused by surgery is an important clinical issue that seriously affects postoperative rehabilitation and health-related quality of life. Failure to effectively manage postoperative pain not only leads to a decrease in patient quality of life, increases medical expenses, but also has a negative impact on patient recovery. Therefore, it is of great clinical significance to address the challenges of acute postoperative pain management, find effective management strategies, and improve the quality of pain management. This article summarizes the current status of acute postoperative pain management in recent years, including the mechanism of pain occurrence, pain assessment methods, drug and non drug management strategies, and predictive factors for chronic postoperative pain. It also looks forward to future research directions and application prospects.

OBJECTIVETo investigate the roles of Domain I and Domain II of hepatitis C virus (HCV) 5' untranslated region (UTR) in the translation initiation activity of HCV 5'UTR in different host cell lines.

METHODSThe eukaryotic expression plasmid pCMVNCRLuc (pCN1), in which full-length HCV 5'UTR regulates firefly luciferase expression, was modified by deleting Domain I and the downstream single-stranded sequence (43 bp in total) from the UTR (pCNl-d2), Domain I with the downstream single-stranded sequence and Domain II (118 bp in total) from the UTR (pCNl-d3), or the total UTR (pCNl-d5). The modified plasmids were transfected via liposome into different cell lines with pRL-TK plasmid co-transfected as the normalization control. At 36 h after the transfection, the total cellular RNA was harvested for semi-quantitative RT-PCR, and the relative expression activities of luciferase were assayed with a dual luciferase reporter gene assay system. The translation initiation activities of the truncated HCV 5'UTRs in different translation systems were analyzed.

RESULTSDeletion of Domain I and the downstream single-stranded sequence caused no significant changes of the translational activity of HCV 5'UTR in Hela or C6 cells, but decreased the translational activity by 46% in L-02 cells and increased the translational activity by 46% in 293T cells. Deletion of both Domain I and Domain II resulted in decreased translational activity of HCV 5'UTR by 51% in HeLa cells, but increased the translational activity by 40% in L-02 cells, 60% in C6 cells and 135% in 293T cells.

CONCLUSIONSDomain I and Domain II of HCV 5'UTR perform cell type-specific roles in HCV IRES-driven translation initiation.

Objective:To investigate the risk factors for bleeding and thrombosis during extracorporeal membrane oxygenation (ECMO) therapy in critically ill patients and determine the best predictors of coagulation-related complications.Methods:A retrospective analysis was performed on patients who received ECMO for respiratory or circulatory failure at Xiangya Hospital of Central South University from January 2020 to December 2022. The outcome was whether bleeding or thrombosis occurred from 24 h after ECMO insertion to before weaning. The differences in demographic characteristics, weaning conditions, prognosis, routine blood tests, organ function, coagulation and blood product transfusion of each group were compared. Logistic regression analysis was used to evaluate the risk factors for bleeding and thrombosis, and ROC curve evaluation was used to assess their capacity to predict complications.Results:A total of 61 patients with ECMO were enrolled, with 21 cases of bleeding and 14 cases of thrombosis during ECMO. Compared with the nonbleeding group, the activated partial thromboplastin time, thromboplastin time (TT), and transfusions of frozen plasma and red blood cells were higher in the bleeding group (all P<0.05). Compared with the nonthrombotic group, the increase in body weight, D-dimer (DD), fibrinogen degradation product (FDP), and improvement of arterial oxygen partial pressure (ΔPO 2) within 24 h were significantly higher in the thrombotic group (all P<0.05). Logistic regression analysis revealed that TT ( OR=1.039, 95% CI: 1.006~1.072, P=0.018) and frozen plasma transfusion volume ( OR=1.046, 95% CI: 1.010-1.083, P=0.012) were risk factors for bleeding events. FDP ( OR=1.030, 95% CI: 1.009-1.051, P=0.005), DD ( OR=1.181, 95% CI: 1.044-1.336, P=0.008), and ΔPO 2 ( OR=1.007, 95% CI: 1.002-1.012, P=0.006) were risk factors for thrombosis. According to ROC curve analysis, the AUCs of TT, frozen plasma transfusion, and combined indexes for predicting bleeding were 0.712, 0.690, and 0.816, respectively. The combined indices had a cut-off value of 0.273, a sensitivity of 75.61%, and a specificity of 80.00%. The AUCs of FDP, DD, ΔPO 2, and combined FDP with ΔPO 2 for predicting thrombosis were 0.778, 0.748, 0.786, and 0.868, respectively. The cut-off value of the combined index was 0.157, the sensitivity was 68.09%, and the specificity was 92.86%. Conclusions:TT combined with frozen plasma transfusion volume predicted bleeding optimally, while FDP plus ΔPO 2 predicted thrombotic events better during ECMO treatment in critically ill patients.

Objective:To analyze the relationship between antithrombin Ⅲ(AT-Ⅲ) activity and survival, bleeding and thrombosis complications in patients with acute-on-chronic liver failure (ACLF), and to explore the prediction value of AT-Ⅲ activity in the prognosis of ACLF patients.Methods:The clinical data of 130 hospitalized patients with ACLF were retrospectively collected in Wuxi No.5 People′s Hospital from January 1, 2013 to April 1, 2019. The liver function, international normalized ratio (INR), and 90-day survival rate were detected. The AT-Ⅲ activity values at admission, week two, week four, and week eight of hospitalization were recorded, and the occurrences of fecal occult blood and femoral vein thrombosis were also recorded. The measurement data were compared by t test, analysis of variance, or rank sum test, and the categorical data were compared by chi-square test. The risk factors affecting the survival of ACLF patients were analyzed by Cox regression. The survival analysis was performed using the Kaplan-Meier method. Results:At the end of 90-day follow-up of 130 patients, 56 patients died, 20 patients (15.38%) were fecal occult blood positive and 15 (11.54%) had femoral vein thrombosis. The baseline AT-Ⅲ activity in the death group was lower than that in the survival group ((17.89±13.68)% vs (36.03±11.96)%), and the difference was statistically significant ( t=-8.045, P<0.01). The baseline AT-Ⅲ activities in fecal occult blood positive and negative patients were (18.26±11.52)% and (25.06±10.97)%, respectively, and in femoral vein thrombosis and non-thrombotic patients were (17.55±10.33)% and (32.48±11.88)%, respectively. The differences were both statistically significant ( t=8.746 and 8.090, respectively, both P<0.01). Through dynamic monitoring of AT-Ⅲ, the AT-Ⅲ activity showed a downward trend in the death group, while that showed an upward trend in the survival group, but the differences were not statistically significant ( F=0.282 and 0.401, respectively, both P>0.05). The Cox regression analysis suggested INR (odds ratio ( OR)=1.364, 95% confidence interval ( CI) 1.078-1.726, P=0.010) and AT-Ⅲ activity ( OR=0.930, 95% CI 0.906-0.954, P<0.01) were the independent factors affecting the survival of patients with ACLF. The area under the receiver operator characteristic curve of the AT-Ⅲ activity for predicting 90-day survival outcome of the patient was 0.706 (95% CI 0.773-0.952, P<0.01), and the cut-off value was 25%. Patients with AT-Ⅲ activity ≥ 25% had a higher survival rate than those with AT-Ⅲ activity <25% ( χ2=58.20, P<0.01). Conclusions:AT-Ⅲ activity is associated with fecal occult blood positive and femoral vein thrombosis in ACLF patients. The AT-Ⅲ activity is an independent influencing factor for predicting the prognosis of ACLF patients. Patients with AT-Ⅲ activity less than 25% have the higher mortality rate.

Objective:To investigate the clinical effect of deep brain stimulation (DBS) in the treatment of Parkinson′s disease (PD).Methods:32 PD patients treated in Hunan Brain Hospital from January 2016 to December 2018 were selected for the study. Guided by MRI and supplemented by electrophysiological stimulation to correct the target, PD patients were treated with DBS for the nucleus accumbens. Based on Webster and Unified Parkinsons Disease Rating Scale (UPDRS) scores before and after DBS treatment, the clinical treatment effects were evaluated. And the content of Aβ1-42, interleukin (IL)-1β, IL-6, uric acid (UA), malondialdehyde (MDA), homocysteine (Hcy), S-nitrosylated dynamin-relatedprotein 1 (SNO-Drp1) and Drp1 was measured before and after DBS treatment. The ratio of SNO-Drp1/Drp1 was also measured.Results:The Webster score and UPDRS score of PD patients after DBS treatment were lower than those before DBS treatment ( P<0.05). The Aβ1-42 and Drp1content of PD patients after DBS treatment was higher than that before DBS treatment ( P<0.05), while the content of IL-1β, UA, MDA, Hcy and the ratio of SNO-Drp1/Drp1 were lower than before treatment ( P<0.05). Conclusions:DBS has confirmed a good clinical effect in the treatment of PD patients and significantly improved the quality of life of patients.

OBJECTIVE: To explore the effect of dust exposure, type of work, age, length of service and duration of dust exposure on pulmonary function in coal miners by pulmonary function tests.
 METHODS: A total of 1 953 coal miners, who received occupational healthy examination and pulmonary function tests during June, 2013 and August, 2014 in Hunan Prevention and Treatment Institute, were enrolled for this study.
 RESULTS: A total of 1 302 miners (66.7%) displayed pulmonary dysfunction, including 1 139 with mild dysfunction (58.3%) and 163 with moderate or more serious dysfunction (8.3%). The risk factors for pulmonary dysfunction were age (OR=1.329, 95% CI: 1.196-1.620), dust exposure duration (OR=1.267, 95% CI: 1.136-1.413) and type of works (mining workers OR=1.156, 95% CI: 1.033-1.293; all P<0.05).
 CONCLUSION The incidence rate of pulmonary dysfunction in coal miners is relatively high in Hunan Province. Most of them are mild dysfunction. The incidence rate of pulmonary dysfunction in mining works is statistically higher than that in other work types. Older workers and long duration-exposed workers are more likely to have pulmonary dysfunction.

OBJECTIVE: To study the effect of underground work on cardiovascular system health in coal miners.
 METHODS: Male coal miners, who received electrocardiographic examinations between June, 2013 and August, 2014 in Hunan Prevention and Treatment Institute for Occupational Diseases to exclude pneumoconiosis, were enrolled for this study (n=3 134). Miners with 2 years or more underground work experience were selected as the exposed group (n=2 370), while miners without underground work experience were selected as the control group (n=764). The prevalence of electrocardiographic abnormalities and the influential factors were compared between the 2 groups.
 RESULTS: The prevalences of electrocardiographic abnormalities, hypertension, heart rate abnormalities and cardiovascular system abnormalities in the exposed group vs the control group were 37.6% vs 25.4%, 20.5% vs 13.4%, 5.7% vs 6.0%, 49.8% vs 35.2%, respectively. The cardiovascular system abnormalities were correlated with the underground work (OR=3.128, 95% CI: 1.969-4.970), the underground work experience (OR=1.205, 95% CI: 1.070-1.358) and the type of works (mining worker OR=1.820, 95% CI: 1.527-2.169; auxiliary worker OR=1.937, 95% CI: 1.511-2.482; other worker OR=3.291, 95%CI: 2.120-5.109).
 CONCLUSION Underground work may increase the prevalence of cardiovascular system abnormalities for coal miners. The longer the coal miners work in underground, the higher the risk of the cardiovascular system abnormalities they are.
