Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

Objective:To explore the effect of nursing intervention based on self-regulation theory on the self-care ability and mood state of patients with hepatitis B.Methods:From July 2021 to June 2023, a total of 126 patients with hepatitis B in the Department of Infectious Diseases in the First Affiliated Hospital of Zhengzhou University were selected as the research objects by the convenient sampling method. They were divided into the control group ( n=63) and the intervention group ( n=63) using the simple random number method. The control group received routine nursing intervention, while the intervention group received nursing intervention based on self-regulation theory based on routine nursing intervention. The intervention period was six months. Self-care ability, mood state, regular follow-up rate, medication compliance rate, and nursing satisfaction before and after intervention were compared between the two groups. Results:After six months of intervention, the score of the Exercise of Self-Care Agency Scale (ESCA) and the score of energy dimension in Profile of Mood states-short form (POMS-SF) in the intervention group were both higher than those in the control group? ( P<0.05), while scores of confusion, fatigue, anger, tension, and depression dimensions in POMS-SF were lower than those in the control group ( P<0.05). The intervention group's regular follow-up rate, medication compliance rate, and nursing satisfaction were all higher than those of the control group ( P<0.05) . Conclusions:Nursing intervention under the theoretical framework of self-regulation can improve the self-care ability of hepatitis B patients, their mood state, the regular follow-up rate, medication compliance rate, and nursing satisfaction.

Purpose: This study examined the diagnostic value of high-frequency ultrasound (HFUS) features in differentiating between benign and malignant skin lesions. Methods: A total of 1,392 patients with 1,422 skin lesions who underwent HFUS examinations were included in an initial dataset (cohort 1) to identify features indicative of malignancy. Qualitative clinical and HFUS characteristics were recorded for all lesions. To determine which HFUS and clinical features were suggestive of malignancy, univariable and multivariable logistic regression analyses were employed. The diagnostic performance of HFUS features combined with clinical information was evaluated. This assessment was validated using internal data (cohort 2) and multicenter external data (cohort 3). Results: Features significantly associated with malignancy included age above 60 years; lesion location in the head, face, and neck or genital regions; changes in macroscopic appearance; crawling or irregular growth pattern; convex or irregular base; punctate hyperechogenicity; blood flow signals; and feeding arteries. The area under the receiver operating characteristic curve, sensitivity, and specificity of HFUS features combined with clinical information were 0.946, 92.5%, and 86.9% in cohort 1; 0.870, 93.1%, and 80.8% in cohort 2 (610 lesions); and 0.864, 86.2%, and 86.6% in cohort 3 (170 lesions), respectively. However, HFUS is not suitable for evaluating lesions less than 0.1 mm in thickness or lesions exhibiting surface hyperkeratosis. Conclusion In a clinical setting, the integration of HFUS with clinical information exhibited good diagnostic performance in differentiating malignant and benign skin lesions. However, its utility was limited in evaluating extremely thin lesions and those exhibiting hyperkeratosis.

Progressive functional deterioration in the cochlea is associated with age-related hearing loss (ARHL). However, the cellular and molecular basis underlying cochlear aging remains largely unknown. Here, we established a dynamic single-cell transcriptomic landscape of mouse cochlear aging, in which we characterized aging-associated transcriptomic changes in 27 different cochlear cell types across five different time points. Overall, our analysis pinpoints loss of proteostasis and elevated apoptosis as the hallmark features of cochlear aging, highlights unexpected age-related transcriptional fluctuations in intermediate cells localized in the stria vascularis (SV) and demonstrates that upregulation of endoplasmic reticulum (ER) chaperon protein HSP90AA1 mitigates ER stress-induced damages associated with aging. Our work suggests that targeting unfolded protein response pathways may help alleviate aging-related SV atrophy and hence delay the progression of ARHL.

Objective:To analyze the survival time, prognostic factors and the value of postoperative thoracic radiotherapy in resected small cell lung cancer (SCLC) patients.Methods:Clinic opathological data of SCLC patients who received surgical treatment in Cancer Hospital & General Hospital of Ningxia Medical University from April 2014 to September 2021 were enrolled in this retrospective study. All patients were subject to follow-up. The survival time of SCLC patients was evaluated by Kaplan-Meier method. Univariate and multivariate analyses of prognostic factors were performed by Cox proportional hazard model.Results:A total of 64 patients with SCLC were enrolled in the study. The 5-year overall survival (OS) rate was 43.5%. Univariate analysis showed that TNM staging ( P=0.027), postoperative neutrophil-lymphocyte ratio (NLR) ( P=0.039) and adjuvant thoracic radiotherapy ( P=0.041) were the prognostic factors. Multivariate analysis showed that TNM staging ( P=0.038) and adjuvant thoracic radiotherapy ( P=0.022) were the prognostic factors in patients with SCLC. The 5-year OS rates of patients with and without adjuvant thoracic radiotherapy were 71.6% and 35.4% ( P=0.028), respectively. There was a statistically significant difference in the 5-year OS rates between pathological stage N 2 SCLC patients with or without adjuvant thoracic radiotherapy (75.0% vs. 0%, P=0.030). Conclusions:TNM staging and postoperative adjuvant thoracic radiotherapy are prognostic factors in patients with SCLC undergoing surgical treatment. Pathological stage N 2 SCLC patients can benefit from adjuvant thoracic radiotherapy.

Objective:The investigation and research on the application status of Hepatic Venous Pressure Gradient (HVPG) is very important to understand the real situation and future development of this technology in China.Methods:This study comprehensively investigated the basic situation of HVPG technology in China, including hospital distribution, hospital level, annual number of cases, catheters used, average cost, indications and existing problems.Results:According to the survey, there were 70 hospitals in China carrying out HVPG technology in 2021, distributed in 28 provinces (autonomous regions and municipalities directly under the central Government). A total of 4 398 cases of HVPG were performed in all the surveyed hospitals in 2021, of which 2 291 cases (52.1%) were tested by HVPG alone. The average cost of HVPG detection was (5 617.2±2 079.4) yuan. 96.3% of the teams completed HVPG detection with balloon method, and most of the teams used thrombectomy balloon catheter (80.3%).Conclusion:Through this investigation, the status of domestic clinical application of HVPG has been clarified, and it has been confirmed that many domestic medical institutions have mastered this technology, but it still needs to continue to promote and popularize HVPG technology in the future.
