Objective To investigate the predictive value of the combined tumor burden score (TBS) and platelet-albumin-bilirubin (PALBI) score model for postoperative tumor recurrence in liver transplant recipients with hepatocellular carcinoma (HCC). Methods The general information of 158 recipients diagnosed with HCC and underwent liver transplantation at the 900th Hospital of the Joint Logistics Support Force of the Chinese People's Liberation Army from 2008 to 2021 was collected. Lasso regression analysis combined with multivariate Cox regression analysis were used to identify independent risk factors for postoperative tumor recurrence after liver transplantation with HCC. A nomogram prediction model was constructed based on variables selected by Lasso regression analysis, and the predictive performance of the model was verified by calibration curve and clinical decision curve. The optimal cut-off values for postoperative tumor recurrence in liver transplant recipients with HCC were determined by receiver operating characteristic (ROC) curve, and Kaplan-Meier analysis was used to compare survival differences among different groups. Results Among the 158 liver transplant recipients with HCC, 82 experienced tumor recurrence, with a recurrence rate of 51.9% and a median tumor-free survival time of 10 (4, 25) months. Results of Lasso regression analysis and multivariate Cox regression analysis showed that alpha-fetoprotein (AFP) ≥400 ng/mL, TBS and PALBI score were all independent risk factors for postoperative tumor recurrence in liver transplant recipients with HCC (all P<0.05). The combined high TBS-high PALBI score showed the highest predictive value (hazard ratio 6.909, 95% confidence interval 3.067-15.563, P<0.001). A nomogram prediction model was constructed based on six variables selected by Lasso regression analysis. Calibration curve showed good consistency between the model's predicted results and the ideal curve. Decision curve analysis indicated that the nomogram prediction model provided the highest clinical benefit for predicting 1-year tumor-free survival after liver transplantation with HCC. Time-dependent ROC curves at 1, 3 and 5 years after surgery showed that TBS-PALBI model had good predictive performance, with no significant difference in area under the curve (AUC) compared with TBS-PALBI-AFP model. The optimal cut-off values for predicting postoperative tumor recurrence were determined by ROC curve, with a PALBI score cut-off of −2.334 and a TBS cut-off of 5.305. Recipients were divided into a low TBS-low PALBI score group (n=47) and a low/high TBS-low/high PALBI score group (at least one score was high) (n=111). Kaplan-Meier survival analysis showed that the low TBS-low PALBI score group had a higher tumor-free survival rate than the low/high TBS-low/high PALBI score group, with a significant difference (P<0.05). Conclusions TBS-PALBI model provides a novel, simple and effective tool for assessing the prognosis of liver transplant recipients with HCC. The nomogram model constructed based on this has significant advantages in predictive performance and may serve as a reference for guiding individualized treatment plans and improving clinical outcomes.

Objective To investigate the distribution of high-risk human papillomavirus(HR-HPV)subtypes and risk factors in Jiaxing,so as to provide reference for cervical cancer screening in high-risk population.Methods A total of 22 573 women from Zhejiang cervical cancer screening project management system from April to October 2023 were selected for HR-HPV screening,and they were divided into HR-HPV positive group(2045 cases)and negative group(20 528 cases).The medical history data of the patients were analyzed,and the risk factors of HR-HPV infection were analyzed by univariate and multivariate regression analysis.Results The overall HR-HPV infection rate was 9.06％.HPV52 was the most common type in single infection(29.6％),and HPV2 was the most common type in multiple infections(13.0％).There were significant differences between HR-HPV positive group and negative group in age,education level,gravidity,number of abortions and different neighborhoods(P＜0.05).Multivariate Logistic regression analysis showed that age＞45 years old,primary school education or below,gravidity were independent risk factors for HR-HPV infection.Conclusion HPV52 is the predominant type of HR-HPV in Jiaxing.Age＞45 years,primary school education or below,and gravidity are related risk factors for HR-HPV infection.These populations should still focus on screening,which has a pivotal role in the prevention and treatment of cervical lesions.

Objective:To explore the therapeutic mechanism of moxibustion in Crohn disease(CD)-associated intestinal fibrosis by observing its effects on the angiotensin-converting enzyme(ACE)/angiotensin Ⅱ(Ang Ⅱ)/angiotensin Ⅱ type 1 receptor(AT1R)axis in CD mouse models.Methods:Six randomly selected male C57BL/6 mice were assigned to a normal group,while the remaining mice were administered 0.1 mL of 2,4,6-trinitrobenzene sulfonic acid via enema to establish a CD intestinal fibrosis model.After successful modeling,the mice were randomly divided into a model group,a moxibustion group,and a Western medication group,with 6 rats in each group.The normal group and the model group only received grabbing without intervention.In the moxibustion group,mild moxibustion was applied to Qihai(CV6)and bilateral Tianshu(ST25)once a day for 10 min each time over 7 consecutive days.The Western medication group was administered mesalazine suspension via oral gavage once a day for 7 consecutive days.At the end of the intervention,the general condition,disease activity index(DAI)score,and gross colon score of mice in each group were evaluated.Hematoxylin-eosin staining was used to observe and score the histological changes in the colon tissue in each group.Masson staining was used to observe colonic fibrosis and the ratio of collagen-positive areas was analyzed;the expression of Ang Ⅱ in the colon tissue was detected by the enzyme-linked immunosorbent assay;immunohistochemistry and real-time quantitative reverse transcription polymerase chain reaction were used to detect the protein and mRNA expression of ACE and AT1R in the colon tissue,respectively;Western blotting was used to detect the expression of transforming growth factor(TGF)-β1 and connective tissue growth factor(CTGF)in the colon tissue.Results:Compared to the normal group,the DAI score,gross colon score,colonic histological score,collagen-positive area ratio,ACE protein and mRNA,Ang Ⅱ protein,AT1R protein and mRNA,TGF-β1 protein,and CTGF protein in the colon tissue in the model group increased significantly(P<0.01).In contrast,the above indicators in both the moxibustion group and the Western medication group reduced significantly compared to the model group(P<0.01 or P<0.05).There was no statistical difference in these indicators between the moxibustion group and the Western medication group(P>0.05).Conclusion:Moxibustion can alleviate intestinal fibrosis in CD mice,and its therapeutic mechanism may be associated with the regulation of colonic ACE/AngⅡ/AT1R axis.

Objective: To observe the effect of moxibustion on behaviors and related products of tryptophan (Trp) metabolism in the colon of mice with irritable bowel syndrome (IBS), and to explore the mechanism of moxibustion in the IBS treatment.Methods: Twenty-four mice were randomly divided into a normal group, a model group, a moxibustion group, and a probiotic group, with 6 mice in each group. The visceral pain model of IBS was established by enema with 2,4,6-trinitrobenzene sulfonic acid (TNBS) solution. Mice in the moxibustion group were treated with mild moxibustion at bilateral Zusanli (ST36), and those in the probiotic group were treated with probiotics such as Bifidobacterium by gavage. Abdominal withdrawal reflex (AWR) test, elevated plus-maze (EPM) test, and forced swimming test (FST) were performed after treatment. The expression levels of 5-hydroxytryptamine (5-HT) and tryptophan hydroxylase 1 (TPH1) in the colon were detected by immunofluorescence, and the expression levels of Trp, kynurenine (Kyn), and indole-2,3-oxygenase (IDO) in the colon were detected by enzyme-linked immunosorbent assay. Results: Compared with the normal group, the AWR scores were increased significantly in the model group under different pressure values (P<0.01), the open-arm staying time and open-arm entries in the EPM test were decreased significantly (P<0.01, P<0.05), the motionless time in the FST was increased significantly (P<0.01), and the expression levels of colonic Trp, TPH1, IDO, 5-HT, and Kyn were increased significantly (P<0.01) in the models. Compared with the model group, the AWR scores were differently decreased (P<0.05 or P<0.01), the open-arm entries in the EPM test were increased (P<0.05), the motionless times in the FST were decreased (P<0.05), and the colonic expression levels of Trp, TPH1, IDO, and 5-HT were decreased (P<0.01 or P<0.05) in the moxibustion and probiotic groups; the open-arm staying time was significantly increased in the moxibustion group (P<0.01), and the colonic expression level of Kyn was significantly decreased in the probiotic group (P<0.01). Conclusion: Moxibustion at Zusanli (ST36) improves visceral pain and pain mood and down-regulates the expression levels of colonic TPH1, IDO, Trp, 5-HT, and Kyn in IBS mice.

Objective: To explore the effects of lncRNA HULC on hepatocellular carcinoma (HCC) growth by down-regulating miR-29. Methods: The expression levels of HULC and miR-29 in HCC tissues and cells were detected by real-time quantitative PCR (RT-qPCR), and the correlation analysis was performed. After HCC cells were transfected with HULC overexpressed plasmid or siRNA, the expressions of miR-29 and its target gene SETDB1 were determinate by RT-qPCR. According to the bioinformatic prediction of the miR-29 binding site in the HULC sequence, the report gene plasmids were constructed. The HCC cells were co-transfected with miR-29 mimics or miR-29 inhibitor, and the HULC targeted regulation of miR-29 was verified by dual luciferase reporter assay. The effect of miR-29 on the HULC-mediated proliferation in HCC cells was detected by cell count kit 8 (CCK-8) experiment. Expression of tumor proliferation antigen Ki-67 was detected by RT-qPCR.The Hep3B cells were inoculated in mice and miR-29 mimics and miR-29 negative control (NC) further injected into the lesions. The tumor volume was observed, and the expressions of tumor proliferation antigen ki-67 in tumor tissues were detected by immunohistochemical staining. Results: The expression of HULC was significantly up-regulated while the expression of miR-29 was significantly down-regulated in HCC tissues and cells (P<0.01). The level of HULC was negatively correlated with miR-29 in tumor tissues (r=-0.754, P<0.01) and HCC cells (r=-0.865, P<0.05). The in vitro experiments showed that, compared with the blank control group, the expression of miR-29 in HULC overexpressed Huh7 cells was significantly reduced, while the mRNA level of miR-29 target gene SETDB1 was increased (P<0.01). The expression of miR-29 was significantly increased in HULC deleted Hep3B cells, while the mRNA expression of SETDB1 was decreased (P<0.01). Double luciferase reporter gene assay showed that miR-29 mimics significantly inhibited the luciferase activity of Hep3B cells transfected with HULC wide type (psi-HULC-WT) plasmid but had no effect on Hep3B cells transfected with mutant plasmid (psi-HULC-Mut). However, the miR-29 inhibitor antagonized the inhibitory effect of miR-29 mimics on luciferase activity of psi-HULC-WT (P<0.01). Cell proliferation experiments showed that, compared with the control group, the proliferation ability of miR-29 mimics overexpressed Huh7 cells was significantly reduced.After 24, 48 and 72 hours of treatment, the proliferation rates of Huh7 cells in the HULC overexpressed group were (43.87±3.82)%, (83.45±7.46)% and (123.34±8.67)%, respectively, significantly higher than (13.45±1.77)%, (23.54±1.37)% and (38.21±2.09)% of control group (P<0.05). After treatment for 48 and 72 hours, the proliferation rates of miR-29 mimics transfected Huh7 cells were (57.10±1.94)% and (73.76±3.46)%, respectively, significantly lower than (83.45±7.46)% and (123.34±8.67)% of control group (P<0.05). After treatment for 48 and 72 hours, the proliferation rates of Huh7 cells transfected with miR-29 mimics and miR-29 inhibitor group were (76.45±3.24)% and (89.37±4.37)%, respectively, significant higher than (57.10%±1.94)% and (73.76±3.46)% of the control group (P<0.05). After 48 h transfection, the expression of Ki-67 in Huh7 transfected with miR-29 mimics was significantly inhibited compared with the control group (P<0.01). However, the expression of Ki-67 mRNA was increased in Huh7 cells transfected with miR-29 inhibitor (P<0.01). The results of in vivo experiments showed that the tumor volumes of the control group, miR-29 mimics group and miR-29 mimics + miR-29 inhibitors group were (504.0±19.6) mm³, (310.0±24.3) mm³ and (483.7±21.2) mm³, respectively. Injection of miR-29 mimics reduced while miR-29 inhibitor promoted tumorigenesis ability of Huh7 in nude mice (P<0.01). The immunohistochemical staining showed that the average optical density values of Ki-67 protein in tumor tissues of the control group, miR-29 mimics group and miR-29 analogue+ miR-29 inhibitor group were 0.65±0.08, 0.36±0.07 and 0.56±0.06, respectively. The expression level of Ki-67 protein in miR-29 mimics group was significantly reduced (P<0.01) while increased in the miR-29 mimics+ miR-29 inhibitor group (P<0.01). Conclusion LncRNA HULC promotes HCC growth by down-regulating miR-29.
