ObjectiveTo analyse the clinical characteristics of different traditional Chinese medicine （TCM） syndromes in patients with heart failure based on information from electronic medical record. MethodsA cross-sectional study was conducted to collect clinical data of all inpatients with heart failure in the Department of Cardiology， Affiliated Hospital of Liaoning University of Traditional Chinese Medicine from January 1， 2019 to December 31， 2020. A database of clinical TCM data was established to explore the characteristics of clinical data of basic information， syndromes and syndrome element types， and biochemical indexes. The distribution of TCM syndromes and syndrome elements in heart failure patients were also analysed， and the basic information and biochemical indexes of the patients with top 7 different TCM syndrome types were compared. ResultsA total of 1676 inpatients with heart fai-lure were included. The top 7 TCM syndromes of heart failure were syndrome of phlegm turbidity and blood stasis （477 cases， 28.46%）， syndrome of qi deficiency and blood stasis （439 cases， 26.19%）， syndrome of qi deficiency and blood stasis with water retention （274 cases， 16.35%）， syndrome of yang deficiency with water retention （145 cases， 8.65%）， syndrome of qi and yin deficiency （104 cases， 6.21%）， syndrome of qi and yin deficiency with blood stasis （80 cases， 4.77%）， syndrome of heart yang deficiency （59 cases， 3.52%）. Among the 1676 patients， 6 syndrome elements accounted for more than 5%. Blood stasis accounted for the highest proportion of TCM syndrome element type （1292 cases， 77.09%）， followed by qi deficiency （919 cases， 54.83%）， phlegm （498 cases， 29.71%）， water retention （434 cases， 25.89%）， yang deficiency （215 cases， 12.82%） and yin deficiency （191 cases， 11.40%）. Among the 1676 patients， 1308 cases of acute heart failure mainly showed syndrome of phlegm turbidity and blood stasis （386 cases， 29.51%）， and 368 of chronic heart fai-lure mainly showed syndrome of qi deficiency and blood stasis （118 cases， 32.07%）. Patients with syndrome of phlegm turbidity and blood stasis had the shortest disease duration of 0.3 months， while those with syndrome of heart yang deficiency had the longest disease duration of 15 months. The proportion of syndrome of phlegm turbidity and blood stasis was the highest in patients with heart failure combined with coronary artery disease， the proportion of syndrome of qi deficiency and blood stasis with water retention was the highest in patients with heart failure combined with atrial fibrillation， and the proportion of patients with syndrome of qi deficiency and blood stasis with water retention and syndrome of yang deficiency with water retention in those applying diuretics during the hospital stay was the highest with more than 86%. The different 7 TCM syndromes showed statistically difference in patients with complications including coronary artery disease， old myocardial infarction， atrial fibrillation， pre and post-admission medication usage including intravenous vasodilators， cardiac stimulants， diuretics， and level of blood chloride， blood urea， blood creatinine， blood bicarbonate， blood albumin， and blood total bilirubin （P＜0.05）. ConclusionThe most common TCM syndromes in patients with heart failure are syndrome of phlegm turbidity and blood stasis and syndrome of qi deficiency and blood stasis. Different TCM syndromes have different characteristics in gender， disease complications， medication before and after admission， and blood indexes.

Objective To explore the predictive value of CT radiomics and morphological features for the prognosis and survival in non-small cell lung cancer(NSCLC)patients.Methods The clinic data of 300 NSCLC patients(300 lesions)were downloaded from the Cancer Imaging Archive,with 210 randomly selected as the training set and 90 as the test set.According to the prognosis and survival,the patients were divided into two groups with survival period≤3 and＞3 years.3D Slicer software was used to delineate the regions of interest layer by layer in CT images,and the radiomics features were extracted from each region of interest.Both t-test and least absolute shrinkage and selection operator were utilized for radiomics feature screening.Three types of prediction models,namely radiomics model,morphological model and combined model,were constructed with Logistic regression,whose performances were evaluated using the receiver operating characteristic(ROC)curve.Results The differences in radiomics labels and mediastinal lymph node metastasis between the training set and the test set were statistically significant.For radiomics model,morphological model and combined model,the area under the ROC curve was 0.784(95%CI:0.722-0.847),0.734(95%CI:0.664-0.804)and 0.748(95%CI:0.680-0.815)in the training set,and 0.737(95%CI:0.630-0.844),0.665(95%CI:0.554-0.777)and 0.687(95%CI:0.578-0.797)in the test set,which demonstrated that radiomics model had the best diagnostic performance.Conclusion The CT radiomics model can effectively predict the prognosis and survival in NSCLC patients.

Objective:To compare the prognosis of patients with hepatolithiasis-associated intrahepatic cholangiocarcinoma (ICC) and hepatitis B virus (HBV)-associated ICC after radical resection.Methods:The clinicopathological and survival data of 69 patients with ICC undergoing radical resection in the Department of Hepatobiliary and Pancreatic Surgery, Lihuili Hospital Affiliated to Ningbo University from January 2012 to February 2024 were retrospectively analyzed, including 40 males and 29 females, aged (62.9±10.2) years. Patients were divided into the stone group ( n=40, with hepatolithiasis) and HBV group ( n=29, with HBV). Kaplan-Meier method was used for survival analysis, and log-rank test was used for survival rate comparison. Cox proportional hazard regression model was used for multivariate analysis to analyze the effect of hepatolithiasis and HBV on the prognosis. Results:The median overall survival of ICC patients in the stone group was 16 months, and that in the HBV group was 27 months. The 1-, 3-, and 5-year cumulative survivals of the stone group were 56.6%, 23.2%, and 10.3%, respectively, which were lower than those of the HBV group (72.0%, 50.7%, and 43.4%, respectively, χ2=5.95, P=0.015). The median recurrence-free survivals (RFS) of the stone group and the HBV group were 12 months and 23 months, respectively. The 1-year and 3-year RFS of the stone group were 49.2% and 18.1%, which were lower than those of the HBV group (65.0% and 39.8%, respectively, χ2=3.94, P=0.047). Univariate analysis showed that hepatolithiasis was assciated with prognosis ( χ2=5.95, P=0.015). Multivariate Cox regression analysis showed that hepatolithiasis and hepatitis B virus infection had no effect on the prognosis of ICC patients after surgery (all P>0.05). Conclusion:Compared to HBV infection, ICC patients with hepatolithiasis have a worse prognosis. Hepatolithiasis and HBV infection have no effect on the prognosis of ICC after radical resection.

Objective:To investigate the factors influencing recipient liver regeneration after full-size split liver transplantation (fSLT).Methods:The clinical data of patients undergoing split liver transplantation in the Affiliated Li Huili Hospital of Ningbo University from May 2019 to Sep 2023 were retrospectively collected. Graft volume (GV) and initial graft volume (IGV) at (30±7) days after operation were measured, and postoperative liver regeneration rate (LRR) was calculated. The patients undergoing fSLT were divided into high regeneration group and low regeneration group with LRR=30% as boundary. The differences of donor and recipient data and perioperative data between the two groups were compared.Results:A total of 52 patients were included. The low fSLT regeneration group (16 cases) was compared with the high fSLT regeneration group (36 cases), and in high fSLT regeneration group donor age was lower, the donor liver steatosis was less, GRWR was lower, the incidence of hepatitis B virus-related liver disease was lower, the postoperative diagnosis of malignant liver disease was lower, the intraoperative blood loss was less, and the postoperative platelet count was higher. The levels of liver enzyme and total bilirubin (TBiL) were higher than those in high regeneration group ( P<0.05). Conclusions:Donor age, donor liver steatosis, GRWR, hepatitis B virus associated liver disease, and recipient pathogenesis are important factors affecting liver regeneration after fSLT. Postoperative platelet and liver enzyme levels are important indicators for monitoring liver regeneration after fSLT.

Objective:To evaluate the short-term efficacy of split liver transplantation (SLT) in patients with acute-on-chronic liver failure (ACLF).Methods:The clinical data of 9 ACLF patients receiving SLT in our center from Mar 2021 to May 2022 were retrospectively analyzed to evaluate its safety and efficacy.Results:The preoperative APASL ACLF Research consortium (AARC) score of the 9 ACLF patients was 8 points in 1 case, 9 points in 3 cases, 10 points in 3 cases, 11 points in 1 case and 12 points in 1 case, 7 cases were in AARC-ACLF grade 2, and 2 cases in grade 3.In-situ liver splitting was performed in 9 deceased donors, including 4 classical split cases, 5 full size split cases. Among these 9 ACLF patients, 2 received left half liver transplantation, 3 received right half liver transplantation, and 4 received extended right lobe liver transplantation. After transplantation, all 9 recipients were discharged fully recovered, 1 case developed Clavien grade Ⅳa complication and 2 cases developed Clavien grade Ⅲb complication.After SLT treatment the median postoperative hospital stay was 27 days, the 1-year survival rate was 100%, and the organ survival rate was 88.9%.Conclusion:Split liver transplantation is a safe and feasible treatment method for ACLF patients.

Peribiliary glands (PBG) is a kind of microscopic structure around the intra-hepatic bile ducts and extrahepatic bile ducts. PBG not only participates in maintaining the normal physiological function of biliary epithelial tissue, but also plays an important role in its damage and repair process. Biliary tree stem/progenitor cells in PBG are important cell sources of biliary epithelial regeneration and repair. PBG and the surrounding peribiliary vascular plexus are key influencing factors for the occurrence of ischemic-type biliary lesions (ITBL) after liver transplantation. Based on relevant literatures and clinical practice, the authors summarize the function of PBG as well as its relationship with ITBL.

Objective:To study the safety and efficacy of combining portal vein resection and reconstruction (PVR) with resection of perihilar cholangiocarcinoma (PHC).Methods:A total of 104 patients with PHC who underwent hepatectomies for either biliary resection alone or biliary resection combined with PVR from October 2006 to December 2019 at the Department of Hepatopancreatobiliary, Ningbo Medical Center of Lihuili Hospital entered into this study. There were 63 males and 41 females, with the age of (64.4±10.4) years. The control group consisted of 75 patients who underwent biliary resection alone, while the PVR group consisted 29 patients with biliary resection combined with PVR. The patient characteristics and the follow-up outcomes of the two groups were analyzed and compared. Survival analyses were performed using the Kaplan Meier method with the log-rank test.Results:Wedge resection of portal vein, side to side anastomosis in 2 cases, segmental resection and end to end anastomosis in 27 cases. The time taken for PVR and portal vein resection were (12.7±2.9)(range 8 to 18)min and (20.7±7.3)(range 8 to 38) mm, respectively. The estimated blood loss for the PVR group was significantly more than the control group [ M( Q1, Q3)] 800.0 (600.0, 1 500.0) ml vs. 600.0(500.0, 1 000.0) ml ( P<0.05). Based on postoperative pathological studies, the proportion of lymph node metastasis was significantly higher in the PVR group than the control group (58.6% vs. 32.0%, P<0.05). Clavien-Dindo grade Ⅲ and above complications were 30.7%(23/75) and 34.5%(10/29) in the control and PVR groups, respectively ( P>0.05). The re-operation and postoperative 90 days mortality rates were 9.3%(7/75) and 2.7%(2/75) in the control group, compared with 3.4%(1/29) and 0 in the PVR group, respectively (both P>0.05). The 1-, 3- and 5-year survival rates were 81.1%, 44.8% and 36.4% respectively for the control group and 78.1%, 35.9% and 31.4% for the PVR group (χ 2=0.33, P=0.570). Conclusion:When compared to biliary resection alone, biliary resection combined with PVR did not significantly increase postoperative complication and mortality rates, but with comparable long-term survival outcomes. Combined biliary resection with PVR was safe and improved the resection rate in selected patients with locally advanced PHC.

Objective:To explore the feasibility of technological modification and innovation of full-left/full-right liver splitting in situ for donors and examine the safety of clinical application for liver transplantation (LT).Methods:From March 2021 to June 2022, clinical and surgical data are retrospectively reviewed for 27 donors undergoing full-left/full-right liver splitting in situ and the corresponding 49 recipients undergoing full-left/full-right LT.According to the split liver technique used in donor liver surgery, they are divided into conventional split group(group A, 13 cases)and innovative split group(group B, 14 cases). The corresponding recipients are divided into two groups of recipient C(25 cases)and recipient D(24 cases). General profiles, intraoperative findings, type of vascular allocation and short-term outcomes in two groups are compared.After full-size split liver transplantation(fSLT), follow-ups continued until the end of September 2022.Results:There are 23 males and 4 females in donors.The causes of mortality for donors are traumatic head injury(12 cases)cerebrovascular accident(13 cases)and anoxia encephalopathy(2 cases). Baseline characteristics of two groups indicate that body weight and body mass index(BMI)are higher in group B and blood sodium level is lower than that in group A( P<0.05). No statistical differences exist for the others.Liver splitting time is significantly shorter in group B than that in group A(175 vs.230 min, P=0.022). No significant inter-group difference exists in type of vascular allocation.Retrohepatic inferior vena cava(IVC)is split in one case in group A and 10 cases in group B( P=0.001). Among 20 cases of right hemiliver requiring a reconstruction of segment Ⅴ/Ⅷ venous outflow, 12 cases in group A and 3 cases in group B are reconstructed with conventional independent bridging method(independent type)while another 5 cases in group B reconstruct with innovated technique by bridging Ⅴ/Ⅷ vein for splitting IVC with iliac vessel and molding all outflows as one for anastomosis(combined typ e). There is significant inter-group difference( P=0.004). No significant differences exist in operative duration, anhepatic phase or blood loss between groups C and B, except for T tube retaining in 7 cases of group A and 14 cases of group D( P=0.032). Twelve cases developed a total of 26 instances of≥Clavien-Dindo grade Ⅲ complications.Of which, 7 cases in group C and 5 cases in group D show no significant difference in postoperative morbidity.However, for serious biliary complications(≥Clavien Dindo grade Ⅲ), there are 6 cases in group C versus none in group D( P=0.016). Two cases died from postoperative complication with a postoperative mortality rate of 4.1%.Postoperative hospital stay is similar in two groups.And accumulates 6/12-month survivals were 95.9% and 87.7% for grafts and 95.9% and 92.4% for recipients respectively. Conclusions:Operative duration of full-left/full-right liver splitting in situ tends to shorten with an accumulation of a certain amount of cases.Technological modification and innovation in IVC splitting and segment Ⅴ/Ⅷ vein reconstruction should be further validated as both feasible and safe by short-term outcomes of the corresponding recipients.
