The incidence and mortality of hepatocellular carcinoma (HCC) in China are among the highest in the world, imposing a heavy social burden. Liver resection and liver transplantation are the primary radical treatments for HCC, although most patients are no longer able to meet the surgical requirements at initial diagnosis. Yttrium-90 microsphere selective internal radiation therapy (⁹⁰Y-SIRT) has the advantages of shrinking tumors, enlarging residual liver, regressing portal vein tumor thrombus and improving the quality of life, which can be used for conversion, downstaging and bridging therapy for HCC before surgical treatment, enabling patients regain the chance of radical treatment and reducing the postoperative recurrence rate. This review focuses on the clinical application and progress of ⁹⁰Y-SIRT in this field.

Vein graft (VG) failure (VGF) is associated with VG intimal hyperplasia, which is characterized by abnormal accumulation of vascular smooth muscle cells (VSMCs). Most neointimal VSMCs are derived from pre-existing VSMCs via a process of VSMC phenotypic transition, also known as dedifferentiation. There is increasing evidence to suggest that ginger or its bioactive ingredients may block VSMC dedifferentiation, exerting vasoprotective functions; however, the precise mechanisms have not been fully characterized. Therefore, we investigated the effect of ginger on VSMC phenotypic transition in VG remodeling after transplantation. Ginger significantly inhibited neointimal hyperplasia and promoted lumen (L) opening in a 3-month VG, which was primarily achieved by reducing ferroptotic stress. Ferroptotic stress is a pro-ferroptotic state. Contractile VSMCs did not die but instead gained a proliferative capacity and switched to the secretory type, forming neointima (NI) after vein transplantation. Ginger and its two main vasoprotective ingredients (6-gingerol and 6-shogaol) inhibit VSMC dedifferentiation by reducing ferroptotic stress. Network pharmacology analysis revealed that 6-gingerol inhibits ferroptotic stress by targeting P53, while 6-shogaol inhibits ferroptotic stress by targeting 5-lipoxygenase (Alox5), both promoting ferroptosis. Furthermore, both ingredients co-target peroxisome proliferator-activated receptor gamma (PPARγ), decreasing PPARγ-mediated nicotinamide adenine dinucleotide phosphate (NADPH) oxidase 1 (Nox1) expression. Nox1 promotes intracellular reactive oxygen species (ROS) production and directly induces VSMC dedifferentiation. In addition, Nox1 is a ferroptosis-promoting gene that encourages ferroptotic stress production, indirectly leading to VSMC dedifferentiation. Ginger, a natural multi-targeted ferroptotic stress inhibitor, finely and effectively prevents VSMC phenotypic transition and protects against venous injury remodeling.

OBJECTIVES: This study aimed to investigate the perception of dental outpatient care quality from multiple perspectives of administrators, physicians, nurses, and patients and propose nursing care quality evaluation indices that are consistent with the clinical reality to provide reference for the construction of a scientific, systematic, and comprehensive dental outpatient care quality evaluation system. METHODS: A total of 39 interviewees, including 7 administrators, 11 doctors, 11 nurses, and 10 patients, were selected for semi-structured in-depth interviews in five regionally representative tertiary-level A stomatological specialty hospitals nationwide during January-April 2024 by using a multistage sampling method. Colaizzi 7-step analysis was used to analyze and summarize the interview data. Themes were extracted on the basis of the Structure-Process-Outcome (SPO) three-dimensional quality assessment model. RESULTS: Five main themes and 15 secondary themes were extracted from three quality dimensions: structure, process, and result. The related topics of structural quality were as follows: disinfection and isolation norms, equipment and consumable management, nursing manpower ratio and nurse education structure, and emergency capability. The related topics of process quality were as follows: pre-diagnosis risk assessment, patient triage and guidance, communication and attitude, health education, humanistic care, continuous care, specialty operation, and four-hand operation. The related topics of result quality were as follows: satisfaction, adverse event management and analysis, effective complaints and disputes. CONCLUSIONS Structure quality is the foundation, process quality is the core, and result quality is the key in the evaluation of the quality of oral outpatient care. The standardization of disinfection and isolation, equipment and consumable management, allocation of reasonable nursing manpower and post capacity, implementation of high-quality nursing services, and improvement of the quality and satisfaction of medical cooperation are necessary guarantees to ensure the quality of oral outpatient care.

OBJECTIVES: This study aimed to construct an evaluation index system for nursing quality management in outpatient dental clinics based on the structure-process-outcome model and provide an objective standard for the evaluation of nursing quality in outpatient dental clinics. METHODS: Through literature review, multi-subject interviews, and expert meetings, the first draft of the evaluation index for nursing quality management in outpatient dental clinics was formulated. The Delphi method was adopted to select and invite 15 experts in the fields of hospital infection management, nursing management, and specialized oral care from across the country to modify the first draft. RESULTS: The positive coefficients of the experts in the two rounds of consultation were 86.7% and 92.3%, respectively. The total authority coefficients of the experts were 0.791 and 0.717, respectively. The mean scores of the importance and feasibility of the third-level indices in the two rounds of consultation were all ≥4.333; the coefficients of variation were all ≤0.150; and the Kendall's coordination coefficients were 0.308 and 0.184 respectively, with P<0.05 for all. These results indicated that the experts were motivated to participate in this study. They recognized the importance and feasibility of the overall items in this index system, and their opinions were relatively consistent. Finally, an evaluation index system, which included 3 first-level indices, 7 second-level indices, 22 third-level indices, and 69 index connotations, for nursing quality management in outpatient dental clinics was determined. The weights of the three first-level indicators were all 0.333. Patient satisfaction (0.076, outcome dimension), hand hygiene (0.061, outcome dimension), chair care ratio (0.057, structural dimension), and turnover rate (0.057, structural dimension) were the top tertiary indicators in terms of portfolio weight. CONCLUSIONS The construction method of the evaluation index system for nursing quality management in outpatient dental clinics is scientific and reliable. It can provide a reference for the evaluation of the management level of nursing quality in outpatient dental clinics and promote the continuous improvement of nursing quality in outpatient dental clinics.

Objective:To investigate the association between exposure to major air pollutants (including PM 2.5, PM 10, NO 2, SO 2, O 3 and CO) and 28-day all-cause mortality in patients admitted to the intensive care unit (ICU). Methods:The electronic medical records of critically ill patients admitted to the ICU in Hubei Province General Hospital and Jingzhou Central Hospital were collected from August 2018 to August 2019 and from May 2021 to May 2022. Patients' exposure to air pollutants was assessed based on the average concentrations at their place of residence during the previous two months. A generalized linear regression model was used to estimate the association between air pollutant exposure and 28-day all-cause mortality in critically ill patients. Subgroup analysis was then conducted to examine the impact of individual air pollutant exposure on 28-day mortality, which served as the primary outcome in this study. The effect size and confidence interval were adjusted for patient characteristics including age, gender, smoking or drinking habits, length of hospital stay, and SOFA score. Additionally, mediation analysis was conducted using the mediation package (Bruce R) in R software. The direct effect represented the association between exposure to air pollutants and risk of mortality, while the indirect effect aimed to assess whether neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and monocyte- lymphocyte ratio (MLR) served as mediating variables in the correlation between exposure to air pollutants and mortality risk.Results:The study included a total of 3 772 critically ill patients admitted to the ICU, with a 28-day all-cause mortality rate of 40.0% (1 509/3 772). A significant positive correlation was observed between an incremental increase of 1 μg/m 3 in air pollutants (specifically PM 2.5, NO 2 and CO) and an elevated risk of mortality within 28 days among critically ill patients. Conversely, there is an inverse relationship between O 3 levels and mortality risk. Additionally, male gender and SOFA rating >3 scores were identified as independent risk factors for all-cause mortality in ICU patients exposed to NO 2 or CO. The Neutrophil/lymphocyte ratio (NLR) played a mediating role in the correlation between PM 2.5 or CO exposure and mortality risk, accounting for 9.09% or 4.71% of the correlations, respectively. Conclusions:The exposure to air pollutants (PM 2.5, NO 2, CO) significantly associate with a high risk of 28-day all-cause mortality in ICU patients. Even at low levels of air pollution, NO 2, CO remains positively correlate with the mortality risk in critically ill patients, who belong to a vulnerable population.

Objective:To investigate the effect of tele-rehabilitation program on ataxic dysarthria following stroke.Methods:A total of 101 patients with stroke and dysarthria who received treatment at The First People's Hospital of Huzhou between January 2021 and October 2023 were included in this study. They were divided into an observation group ( n = 51) and a control group ( n = 50) using the random number table method. Patients in the control group received conventional family rehabilitation guidance, while those in the observation group participated in a tele-rehabilitation program. All patients were treated for 12 weeks. Before and 12 weeks after the intervention, the Frenchay Dysarthria Assessment (FDA) and speech clarity tests were used to assess speech function. Changes in FDA scores and speech clarity scores post-intervention were compared with pre-intervention scores. The observation group was further divided into mild, moderate, and severe groups based on FDA scores, and the differences in effect of tele-rehabilitation program on ataxic dysarthria among the three groups after the intervention were compared. Results:At 12 weeks after intervention, both the observation and control groups showed improvements in FDA scores and speech clarity [observation group: (43.88 ± 16.13) points, (68.65 ± 16.99)%; control group: (49.68 ± 12.09) points, (62.36 ± 14.20)%] compared with their baseline measurements [observation group: (55.12 ± 12.63) points, (57.96 ± 13.48)%; control group: (54.16 ± 10.69) points, (57.84 ± 12.78)%] ( t = 12.23, -14.01, 12.42, -13.86, all P < 0.001). Moreover, the observation group showed significant improvements compared with the control group ( t = 2.04, -2.01, both P < 0.05). At 12 weeks after intervention, both the mild and moderate groups showed improvements in FDA scores and speech clarity score [mild group: (31.41 ± 3.08) points, (82.94 ± 6.97)%, moderate group: (40.08 ± 4.67) points, (70.92 ± 6.26)%] compared with their baseline measurements [mild group: (42.24 ± 6.78) points, (70.53 ± 7.98)%, moderate group: (56.17 ± 4.65) points, (57.58 ± 6.54)%, t = 10.06, -20.25, 45.21, -21.34, all P < 0.001]. There were no significant improvements in the severe group for FDA scores and speech clarity score [(74.20 ± 4.29) points, (38.90 ± 5.80)%] compared with their baseline measurements [(74.50 ± 4.01) points, (37.50 ± 4.74)%, t = 1.96, -1.44, both P > 0.05]. Conclusion:The tele-rehabilitation program can improve post-stroke ataxic dysarthria, particularly showing significant effectiveness for patients with mild to moderate ataxic dysarthria.

Objective To investigate the effect of magnetic resonance diffusion tensor imaging(DTI)combined with Buyang Huanwu decoction on limb rehabilitation of patients with spontaneous hypertensive cerebral hemorrhage in basal ganglia.Methods A total of 68 patients with spontaneous hypertensive intracerebral hemorrhage in basal from March 2022 to March 2023 were selected from the department of neurosurgery of the First People's Hospital of Huzhou as research object.According to the random number table method,the patients were divided into control group(30 cases)and experimental group(38 cases).The control group was diagnosed with hypertensive intracerebral hemorrhage and received conventional therapy,and the experimental group was treated with DTI combined with Buyang Huanwu decoction.After 4 weeks of treatment,the overall treatment effect of the two groups was compared,and the differences of Fugl-Meyer assessment(FMA),National Institutes of Health Stroke Scale(NIHSS),Berg balance scale(BBS),and modified Barthel index(MBI)scores were compared.Results The overall therapeutic effect of experimental group was significantly higher than that of control group[86.8%(33/38)vs.56.7%(17/30),P<0.05].After 4 weeks of treatment,FMA,BBS and MBI scores were significantly increased in both groups,NIHSS scores were significantly decreased in both groups,and the improvement degree of the experimental group was significantly better than that of the control group(FMA score:74.21±9.07 vs.66.73±12.76,NIHSS score:15.16±3.73 vs.20.27±6.15,MBI score:69.29±14.68 vs.60.63±19.10,BBS score:43.55±4.30 vs.36.90±3.86,all P<0.05).Conclusion DTI combined with Buyang Huanwu decoction can improve the motor function of the limbs of patients in the basal ganglia area and enhance their ability to perform activities of daily living.

Objective To explore the health promotion behaviors among patients with pulmonary tuberculosis(TB),and to analyze its relationship with health locus of control,in order to provide scientific references for improving TB patients'health-promotion behaviors in clinical nursing care.Methods The interpretive sequence mixed method design was utilized.A convenient sampling was used to enroll 300 TB patients from 2 TB specialized tertiary hospitals in Xi'an as research subjects from January to April 2023.General information questionnaire,Health promoting lifestyle profile-Ⅱ,and Multidimensional health locus of control scale were used to collect data,and single-factor analysis and multiple linear regression analysis were conducted.Purposeful sampling was used to select 11 TB patients for a semi-structured interview,and the Colaizzi 7-step method was used to extract themes.Results In the quantitative study,the total score of health promoting behaviors in 294 TB patients was(110.26±15.74).Patients'intemal health locus of control,chance health locus of control,and occupational status significantly influenced their health-promotion behaviors(P＜0.05).In the qualitative study,4 themes were extracted,including awakening self-awareness of health,the desire to establish a normal life,the distress of multiple uncertainties,and the immediate effect of authoritative guidance.The qualitative and quantitative studies complemented each other and further verified the relationship between health promotion behaviors and health locus of control of TB patients.Conclusion The level of health-promotion behaviors in TB patients needs to be further improved.Nurses need to take systematic health education as an opportunity by the catalytic effect of individual health awareness,to improve their internal locus of control,reduce their opportunity control tendency due to multiple uncertainties,with the ultimate purpose of helping TB patients form and maintain health promotion behaviors.

Objective:To explore the causes of blood supply disorder of the pedicled rectus abdominis flap.Methods:Between January 2019 and May 2021, a cohort of 61 female patients, aged 25 to 70 years with a mean age of (46.9±2.1) years, underwent surgical repair for extensive thoracic wall defects at Hunan Province Cancer Hospital. These defects, resulting from thoracic wall tumor resection, were addressed using a combination of pedicled rectus abdominis myocutaneous flaps and free inferior abdominal artery perforator flaps. The patient cohort included 39 cases of locally advanced breast cancer, 12 cases of recurrent breast cancer, 6 cases of lobular cell sarcoma, and 4 cases of soft tissue sarcoma. The patients were divided into two groups according to the order of revascularization sequence of free inferior abdominal artery perforator flap: 31 cases in the group of anastomosing the artery first and then the accompanying vein (group A), and 30 cases in the group of anastomosing the vein first and then the artery (group B). The main reasons for the blood supply disorders of the pedicled rectus abdominis flap were analysed in the two groups.Results:In all 61 patients, the pedicled rectus abdominis myocutaneous flap showed immediate red and purple plaques and other blood supply disorders. Further anastomosis of the free inferior abdominal wall artery perforating the flap vessel tip was conducted to achieve pressurization. The vascular selection for the recipient area included the intrathoracic vessels in 26 cases, the thoracic acromion vessels in 15 cases, the thoracodorsal vessels in 9 cases, the anterior serratus branch of the thoracodorsal vessels in 7 cases, and the lateral thoracic arteries and veins in 4 cases. The flap length measured (29.1±0.6) cm, while the width of the skin island was (12.9±0.6) cm. The follow-up period was from 9 to 16 months, with a mean of 12.7 months.In the Group A, the flap blood supply was significantly relieved before further anastomosing the vein in 7 cases, and the flap blood supply returned to normal in the other 24 cases after further anastomosing the vein. In the Group B, the flap blood supply was significantly relieved before further anastomosing the artery in 27 cases, and the flap blood supply returned to normal in the other 3 cases after further anastomosing the artery.61 flaps survived completely, the shape of reconstructed chest wall was satisfactory, and there was no flap contracture and deformation; only linear scar was left in the donor area of the flap, and there was no significant effect on the function of the abdominal wall. The patients were followed-up for 9-16 months, with an average of 12.7 months.Conclusions:The main reason for the blood supply obstacle of the rectus abdominis flap is the venous return obstacle, in order to ensure the reliable blood supply of the flap, the venous return should be increased as a priority.

Objective:To investigate the effect of pressurized pedicled rectus abdominis flap for breast reconstruction.Methods:A retrospective study was conducted to include 37 female patients with breast cancer who underwent immediate breast reconstruction using a pressurized pedicle rectus abdominis skin flap transplantation after surgery at the Department of Plastic and Reconstructive Surgery, Hunan Provincial Cancer Hospital from March 2019 to December 2022. The patients were aged 29-61 years, with an average age of (37.7±3.5) years. According to the preoperative imaging and ultrasound data, 17 patients were planned to complete immediate breast reconstruction with free inferior abdominal artery perforator flap transplantation, and the operation was adjusted to directly prepare a pedicled rectus abdominis flap with long inferior abdominal vessel pedicle according to the actual situation. In addition, 20 patients were scheduled to use pedicled rectus abdominis flap alone, and the operation was changed according to the actual situation. The flap was trimmed according to the condition of the affected area and immediate intraoperative fluorgraphy. After cutting off the vascular pedicle, the recipient area was placed, and the recipient blood vessels were selected for vascular anastomosis. After shaping, the donor and recipient areas were sutured. The survival of the skin flap was observed.Results:Intraoperative fluorescein angiography was used to determine the blood supply of the flap. It was found that 37 cases of pedicled rectus abdominis flaps had different degrees of blood supply disorders. The affected vessels in the specific anastomosis comprised the intrathoracic vessels (19 cases, 51.4%), the lateral thoracic arterial vein (10 cases, 27.0%), and anterior branches of the thoracic and dorsal vessels (8 cases, 21.6%). In 37 cases, the lateral abdominal wall vein was carried in the flap, 20 of which carried the lateral abdominal wall shallow vein, 17 cases carried the lateral abdominal wall shallow vein, six of which were extra anastomosed and superficial vein, and the actual utilization rate was 16.2%. The follow-up was 47 months, averaging 22.7 months. 37 patients had fair reconstructed breast appearance, good elasticity, and no flap contracture deformation. Only linear scar was left in the flap donor area with no effect on abdominal wall function.Conclusions:Pressurized rectus flap can improve the survival rate and surgical safety.
