Objective To investigate the expression and prognostic value of microRNA-29b-2-5p(miR-29b-2-5p)and syntaxin 16(STX16)in hepatocellular carcinoma(HCC).Methods The cancer tissues and adjacent tissues of 88 HCC patients diagnosed in Nantong Tumor Hospital from January 2013 to September 2020 were collected.The expressions of miR-29b-2-5p and STX16 in cancer tissues and adjacent tissues were analyzed by real-time fluorescent quantitative PCR.The expression of STX16 protein in cancer tissues and adjacent tissues were analyzed by immunohistochemistry.Pearson correlation analysis was used to analyze the correlation be-tween miR-29b-2-5p and STX16.Non-parametric χ2 test was used to analyze the relationship between the ex-pression of the two proteins and clinicopathological parameters,and Kaplan-Meier survival curve was used to analyze the relationship between the expression of the two proteins and prognosis.Results The relative ex-pression level of miR-29b-2-5p was 0.780(0.351,1.708)in cancer tissues and 1.014(0.458,3.124)in adja-cent tissues in 88 HCC patients.The relative expression level of miR-29b-2-5p in cancer tissues was signifi-cantly lower than that in adjacent tissues(P=0.012).The relative expression level of STX16 mRNA was 0.775(0.406,0.946)in cancer tissues and 0.368(0.080,1.301)in adjacent tissues in 88 HCC patients.The relative expression level of STX16 mRNA in cancer tissues was significantly higer than that in adjacent tissues(P<0.01).Immunohistochemical results showed that STX16 was expressed in the cytoplasm,and the expres-sion of STX16 in cancer tissues was higher than that in adjacent tissues(P<0.05).The expression of miR-29b-2-5p in cancer tissues was related to cancer stage(P<0.05),and the expression of STX16 was related to cancer stage and alpha-fetoprotein(P<0.05).Patients with low miR-29b-2-5p expression had a shorter over-all survival(OS)than those with high miR-29b-2-5p expression,and patients with high STX16 expression had a shorter OS than those with low STX16 expression(P<0.05).Conclusion The expression of miR-29b-2-5p is low and STX16 is high in HCC tissues.The combined detection of miR-29b-2-5p and STX16 can effectively evaluate the prognosis of HCC patients.

OBJECTIVE To prepare hyaluronic acid （HA）-modified emodin （EMD）-contained multi-walled carbon nanotubes （MWCNTs） drug delivery system （HA-MWCNTs-EMD） and explore its in vitro inhibitory effect on breast cancer cells. METHODS EMD was loaded onto MWCNTs to prepare a drug delivery system MWCNTs-EMD； subsequently， the system was further modified with HA to obtain the drug delivery system HA-MWCNTs-EMD. The two drug delivery systems mentioned above were characterized. With free EMD as the reference， the drug release in vitro of the above two drug delivery systems was investigated； the uptake of EMD by two breast cancer cells （MCF-7， MDA-MB-231 cells） was detected. The impacts of the above two drug delivery systems on the expression of surface glycoprotein differentiation group 44 （CD44）， activity， apoptosis and lactate dehydrogenase （LDH） release of two breast cancer cells were detected. RESULTS The encapsulation efficiencies of MWCNTs-EMD and HA-MWCNTs-EMD were both （63.52±2.74）%， with drug loading rates of （25.01±1.83）% and （12.13± 1.96）%， particle sizes of （865.95±2.16） and （351.86±1.68） nm， polydispersity indexes of 0.54±0.02 and 0.23±0.01， and Zeta potentials of （23.87±0.14） and （－42.79±0.39） mV， respectively. The 2， 4， 6， 8， 10， 12 and 24-hour cumulative release rates of EMD in MWCNTs-EMD and HA-MWCNTs-EMD were significantly lower than those in free EMD， while the cumulative release rate of HA-MWCNTs-EMD was significantly higher than that of MWCNTs-EMD （P＜0.05）； the EMD uptakes of MWCNTs-EMD and HA-MWCNTs-EMD by the two types of breast cancer cells were significantly higher than their uptake of free EMD （P＜0.05）. Compared with the free EMD group， the MWCNTs-EMD and MWCNTs-EMD groups showed significantly higher apoptosis rate and LDH release， significantly lower surface CD44 expression （except for the MWCNTs-EMD group） and cell viability in both cell types， and the effect of HA-MWCNTs-EMD was more pronounced （P＜0.05）. CONCLUSIONS A novel drug delivery system HA-MWCNTs- EMD loaded with EMD is developed successfully； the drug delivery system has a certain slow-release effect， which can significantly reduce the activity of breast cancer cells， promote their apoptosis and increase the release of LDH， and the above anti- breast cancer effect is significantly stronger than that of free EMD and MWCNTs-EMD.

Objective To introduce a modified technique of right ventricular outflow tract (RVOT) reconstruction using a handmade bicuspid pulmonary valve crafted from expanded polytetrafluoroethylene (ePTFE) and to summarize the early single-center experience. Methods Patients with complex congenital heart diseases (CHD) who underwent RVOT reconstruction with a handmade ePTFE bicuspid pulmonary valve due to pulmonary regurgitation at Guangdong Provincial People’s Hospital from April 2021 to February 2022 were selected. Postoperative artificial valve function and right heart function indicators were evaluated. Results A total of 17 patients were included, comprising 10 males and 7 females, with a mean age of (18.18±12.14) years and a mean body weight of (40.94±19.45) kg. Sixteen patients underwent reconstruction with a handmade valved conduit, with conduit sizes ranging from 18 to 24 mm. No patients required mechanical circulatory support, and no in-hospital deaths occurred. During a mean follow-up period of 12.89 months, only one patient developed valve dysfunction, and no related complications or adverse events were observed. The degree of pulmonary regurgitation was significantly improved post-RVOT reconstruction and during follow-up compared to preoperative levels (P<0.001). Postoperative right atrial diameter, right ventricular diameter, and tricuspid regurgitation area were all significantly reduced compared to preoperative values (P<0.05). Conclusion The use of a 0.1 mm ePTFE handmade bicuspid pulmonary valve for RVOT reconstruction in complex CHD is a feasible, effective, and safe technique.

Radiochemotherapy-induced oral mucositis (OM) is a common oral complication in patients with tumors following head and neck radiotherapy or chemotherapy. Erosion and ulcers are the main features of OM that seriously affect the quality of life of patients and even the progress of tumor treatment. To date, differences in clinical prevention and treatment plans for OM have been noted among doctors of various specialties, which has increased the uncertainty of treatment effects. On the basis of current research evidence, this expert consensus outlines risk factors, clinical manifestations, clinical grading, ancillary examinations, diagnostic basis, prevention and treatment strategies and efficacy indicators for OM. In addition to strategies such as basic oral care, anti-inflammatory and analgesic agents, anti-infective agents, pro-healing agents, and photobiotherapy recommended in previous guidelines, we also emphasize the role of traditional Chinese medicine in OM prevention and treatment. This expert consensus aims to provide references and guidance for dental physicians and oncologists in formulating strategies for OM prevention, diagnosis, and treatment, standardizing clinical practice, reducing OM occurrence, promoting healing, and improving the quality of life of patients.

OBJECTIVE: To explore the role of CDGSH iron-sulfur domain 2 (CISD2) in patients with sepsis-related myocardial injury (SMI) and its predictive value for 28-day prognosis and myocardial damage through clinical studies and cell experiments. METHODS: A retrospective study was conducted. Adult patients diagnosed with sepsis admitted to the critical care medicine of Third Affiliated Hospital of Qiqihar Medical University from January 2023 to January 2024 were enrolled. The clinical data, laboratory indicators, expression level of CISD2 mRNA in peripheral blood mononuclear cells (PBMC) 24 hours after admission, and 28 days prognosis were collected. Patients were divided into SMI group [left ventricular ejection fraction (LVEF) < 0.50 or LVEF decreased by ≥ 10% from baseline] and sepsis non-myocardial injury group based on LVEF. The expression levels of CISD2 mRNA were compared between the two groups, and the correlation between CISD2 and myocardial injury was analyzed. Patients were divided into the low-expression group (CISD2 mRNA < 0.5 copy/μL) and the high-expression group (CISD2 mRNA ≥ 0.5 copy/μL) based on the expression of CISD2 mRNA, and into the survival group and the death group based on the prognosis at 28 days. The clinical characteristics were analyzed between the groups. Multivariate Logistic regression was used to analyze the independent predictors of 28-day mortality in patients with sepsis. The predictive value of CISD2 for myocardial damage and 28-day prognosis in patients with sepsis were evaluated by using the receiver operator characteristic curve (ROC curve). In addition, in vitro experiments using human AC16 cardiomyocytes was conducted. The cells were divided into control group, lipopolysaccharide (LPS) group, the LPS+transfection group with overexpression of CISD2 plasmid (LPS+p-CISD2 group), and the LPS + transfection group with negative control plasmid (LPS+p-NC group). The mRNA expression of CISD2 in cells were detected by real-time quantitative polymerase chain reaction (RT-qPCR), the protein expression of CISD2 in cells were detected by Western blotting, and the cell viability was determined by cell counting kit-8 (CCK-8). RESULTS: A total of 85 sepsis patients were included, with 32 developing myocardial injury and 53 without myocardial injury. There were 40 cases of low expression of CISD2 and 45 cases of high expression of CISD2. At 28 days, 60 cases survived and 25 cases died. The mRNA expression of CISD2 in the SMI group was significantly lower than that in the sepsis non-myocardial injury group (copy/μL: 0.41±0.09 vs. 0.92±0.13, P < 0.05). CISD2 was significantly correlated with myocardial injury in patients with sepsis (r = 0.729, P < 0.05). The proportion of LVEF < 0.50 (67.50% vs. 11.11%), sequential organ failure score (SOFA: 15.63±2.15 vs. 11.12±1.52), and acute physiology and chronic health evaluation II (APACHEII: 29.49±3.51 vs. 22.41±2.61) in the CISD2 low-expression group were significantly higher than those in the CISD2 high-expression group (all P < 0.05), while there were no significantly differences in other indicators. The Kaplan-Meier survival curve showed that the 28-day survival time of sepsis patients with in the CISD2 low-expression group was significantly shorter than that in the CISD2 high-expression group (Log-rank test: χ ² = 5.601, P < 0.05). The proportion of CISD2 low-expression and the proportion of LVEF < 0.50 in the survival group were both higher than those in the death group (80.00% vs. 33.33%, 64.00% vs. 26.67%, both P < 0.05), while there were no significantly differences in other indicators. Multivariate Logistic regression analysis showed that CIDS2 and LVEF were independent predictive factors for 28-day mortality in patients with sepsis [CIDS2: odds ratio (OR) = 3.400, 95% confidence interval (95%CI) was 1.026-11.264, P = 0.045; LVEF: OR = 2.905, 95%CI was 1.029-8.199, P = 0.044]. ROC curve analysis showed that when CISD2 was expressed at a low level, patients with sepsis were at high risk of death within 28 days and myocardial injury. The sensitivity of CISD2 in predicting the 28-day mortality of patients with sepsis was 80.00%, and the specificity was 66.67%, and the area under the curve (AUC) was 0.733 (95%CI was 0.626-0.823). The sensitivity of CISD2 in predicting myocardial injury in patients with sepsis was 83.87%, the specificity was 74.07%, and the AUC was 0.790 (95%CI was 0.688-0.871). In addition, compared with the control group, the mRNA and protein expressions of CISD2 as well as the cell activity in the LPS group were significantly decreased. The mRNA and protein expressions of CISD2 and the activity of cardiomyocytes transfected with p-CISD2 were significantly increased. CONCLUSIONS CISD2 plays a protective role in sepsis-associated myocardial injury and has good predictive value for 28-day prognosis and myocardial injury.
