Objective　To analyze the clinical characteristics and prognostic factors for clinical cure in chronic hepatitis B virus (HBV) infected patients with pegylated interferon-α-2b (PEG-IFN-α-2b) based therapy. Methods　This is a retrospective study. Chronic HBV infected patients receiving PEG-IFN-α-2b therapy were enrolled in Yuncheng Central Hospital affiliated to Shanxi Medical University between August 2020 and November 2023. Treatment-naïve patients received PEG-IFN-α-2b monotherapy, while nucleoside (acid) analogs (NAs)-experienced patients received PEG-IFN-α-2b add-on therapy. The study endpoint was hepatitis B surface antigen (HBsAg) negative in accompany with HBV DNA below the detection limit (course of treatment < 48 weeks) or treatment for 48 weeks. The general characteristics, virological variables, blood routine test, and liver function of patients were collected at baseline and study endpoint. Student’s t test or Mann-Whitney U test was used for comparison. The prognostic factors of clinical cure were examined using univariate and multivariate stepwise logistic regression models. Results　A total of 61 chronic HBV infected patients were enrolled, including 39 males and 22 females. The age were (39.13±7.53) years. Twenty-one cases were treatment-naïve, while 40 patients were NAs-experienced. Nineteen cases were positive for HBV DNA at baseline. The baseline HBsAg levels were 211.30(50.93, 2 110.00) IU/mL. Thirty-four patients achieved clinical cure at the study endpoint with 25.50 weeks of median course of PEG-IFN-α-2b treatment. Twenty-seven patients did not achieve clinical cure at the study endpoint, and the course of treatment was 48 weeks. Clinical cure group had significant lower baseline HBsAg level when compared with non-clinical cure group [78.66(19.54, 204.60) IU/mL vs 2 078.00(442.20, 4 237.00) IU/mL, P<0.001]. At the study endpoint, the white blood cell, platelet, red blood cell, hemoglobin levels were lower than those in baseline (P<0.05), while alanine aminotransferase and asparatate aminotransferase levels were higher than those in baseline (P<0.05). There were no remarkable differences in blood routine tests or liver function between clinical cure and non-clinical cure group at either baseline or study endpoint (P>0.05). Baseline low HBsAg level was a predictor for clinical cure in patients receiving PEG-IFN-α-2b therapy (OR=0.998, 95%CI: 0.998-0.999). No severe adverse events were happened during therapy. Conclusion　PEG-IFN-α-2b-based therapy was well-tolerant, and could achieve high rate of clinical cure in chronic HBV-infected patients who had low baseline HBsAg level.

Basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC), as certain forms of non-melanoma skin cancer (NMSC) or keratinocyte carcinoma, are the most common forms of malignant neoplasms worldwide (Sharp et al., 2024). BCC and cSCC have been identified as two major components of NMSC, comprising one-third of all malignancies (Burton et al., 2016). Generally speaking, patients with NMSC tend to have relatively favorable survival outcomes, while different histopathological subtypes of NMSC exhibit distinct biological behaviors (Stătescu et al., 2023). Keratinocyte carcinoma, although not considered as deadly as melanoma, tends to metastasize if left untreated (Civantos et al., 2023; Nanz et al., 2024). cSCC can evolve locally, then aggressively metastasize, invade, and even lead to fatal consequences in a subset of patients (Winge et al., 2023). A solid, pigmented, smooth plaque or a hyperkeratotic papule with or without central ulceration and hemorrhage appears to be characteristic of cSCC (Thompson et al., 2016; Zhou et al., 2023). Of note, a rare type of intraepidermal cSCC in situ often appears as a velvety, demarcated, slightly raised erythematous plaque on the genitalia of men (Yamaguchi et al., 2016). Accounting for approximately 16.0% of scalp tumors and with a rising incidence, cSCC is now the second most common NMSC in humans (Verdaguer-Faja et al., 2024). According to the latest statistics, up to 2%‒5% of cSCCs in situ may gradually progress into invasive cSCCs in the final step (Rentroia-Pacheco et al., 2023). Several risk factors for the carcinogenesis and development of cSCC have been identified, including age, accumulative exposure to ultraviolet light radiation A and B, human papillomavirus infection, arsenic ingestion, chronic scarring, xeroderma pigmentosa, a relevant history of ionizing radiation, androgenetic alopecia in males, and immunosuppression therapy (Martinez and Otley, 2001; Welsch et al., 2012; Mortaja and Demehri, 2023).

Objective To explore the effects of home-based exercise rehabilitation on cardiac structure, valvular function, and exercise capacity in patients with severe aortic stenosis (AS) after transcatheter aortic valve replacement (TAVR). Methods 49 patients with severe AS who underwent TAVR at Zhongshan Hospital, Fudan University, from January 2024 to February 2025 were enrolled. They were divided into an exercise group (n＝25) or a non-exercise group (n＝24) based on participating or not in home-based rehabilitation after TAVR. The exercise group received 12 weeks of home-based exercise training (aerobic exercise plus resistance training every week); the non-exercise group received routine care. Transthoracic echocardiography (TTE) was used to assess cardiac structural parameters before discharge (T0) and after 12 weeks of exercise (T1). Functional outcomes including the 6-minute walk test (6MWT), Duke Activity Status Index (DASI), and Short Physical Performance Battery (SPPB) were compared between the two groups. A linear mixed-effects model was used to analyze the effect of home-based rehabilitation on echocardiographic parameters. Patients were stratified by baseline 6MWT (＜240 m as low-function subgroup, ≥240 m as high-function subgroup) to compare exercise-related outcomes between subgroups. Results At T1, the exercise group had a longer 6MWT distance than the non-exercise group (P＝0.012). The linear mixed-effects model showed that after 12 weeks of exercise, the left ventricular end-diastolic diameter (LVEDD) decreased in the exercise group but slightly increased in the non-exercise group, with a significant difference in changes over time between the two groups (P_interaction＝0.030). The exercise group also showed greater improvement in effective orifice area index (P_interaction＝0.028) and effective orifice area (P_interaction＝0.042) than the non-exercise group. Subgroup analysis revealed that in the low-function subgroup, the exercise group showed greater improvement in the 6MWT (P_interaction＝0.035) and the effective orifice area index (P_interaction＝0.046) compared to the non-exercise group; in the high-function subgroup, the exercise group showed greater improvement only in LVEDD compared to the non-exercise group (P_interaction＝0.046). Conclusions Home-based exercise rehabilitation improves exercise capacity, optimizes left ventricular remodeling, and enhances valvular function in patients with severe AS after TAVR, with greater benefits observed in patients with lower baseline 6MWT.

Chronic eczema is clinically characterized by pruritus and skin lesions such as macules,exudation,desquamation,and lichenification.Traditional Chinese medicine(TCM)typically attributes its pathogenesis to wind,dampness,and heat pathogens,and TCM treatment for chronic eczema focused on dispelling wind,eliminating dampness,and clearing heat.However,there were fewer reports about the treatment of accompanying emotional changes and sleep disturbances in chronic eczema patients.This paper integrated the physique-qi-spirit trinity life view with zang-fu organ differentiation,and proposed that the disorder of spleen transportation and transformation contributed to the pathological foundation of chronic eczema,while the dysfunction of heart and liver was the factor that significantly influenced disease progression after analyzing the clinical features of chronic eczema.For the treatment of chronic eczema,the establishment of strategies should consider clinical characteristics,duration of disease,and skin lesion patterns.The combination of physique-qi-spirit regulation with heart-liver-spleen treatment approaches aims to alleviate clinical symptoms,improve quality of life,and enhance therapeutic efficacy for chronic eczema patients.

Objective To investigate the application value of the global myocardial work parameters in the non-invasive pressure-strain loop (PSL) technology for early assessment of left ventricular systolic function in patients with chronic kidney disease (CKD). Methods A retrospective analysis was performed on 74 patients with normal left ventricular ejection fraction (LVEF) who were hospitalized in the Nephrology Department of Zhongshan Hospital (Xiamen Branch), Fudan University, from August 2021 to December 2021. Based on CKD stages, patients were divided into early group (CKD stages 1-3) and advanced group (CKD stages 4-5). Additionally, 30 healthy volunteers matched for age and gender were selected as the control group. General clinical data, routine left ventricular ultrasound indicators, myocardial strain, and global myocardial work parameters were collected and compared among the three groups. Correlation analysis and multiple linear regression were used to assess the influencing factors of myocardial work. Results There were no statistically significant differences in global work index (GWI) and global constructive work (GCW) among the three groups. Compared to the control group, both CKD groups showed significantly reduced global work efficiency (GWE), along with significantly increased global waste work (GWW, P＜0.05). The absolute value of global longitudinal strain (GLS) in the advanced CKD group (n＝42) was significantly lower than that in the early CKD group (n＝32; [﹣17.09±0.82]% vs [﹣18.33±0.90]%, P＜0.05), and GWE was also significantly lower (93.00%[90.00%, 95.00%] vs 96.00%[92.25%, 96.75%], P＜0.05), while GWW was significantly higher than that in the early CKD group (150.00 mmHg%[105.25 mmHg%, 215.00 mmHg%] vs 88.00 mmHg%[64.25 mmHg%, 144.50 mmHg%], P＜0.05). Correlation analysis showed that GWE was negatively correlated with the absolute value of GLS and peak strain dispersion (PSD; r＝﹣0.396, ﹣0.558, P＜0.05), GWW was positively correlated with absolute value of GLS, and PSD (r＝0.341, 0.610, P＜0.01). Multiple linear regression results indicated that PSD was an independent influencing factor for GWE (β＝﹣0.558, P＜0.001) and GWW (β＝0.538, P＜0.001). Conclusions The myocardial work parameters GWE and GWW in non-invasive left ventricular PSL technology can identify subclinical left ventricular systolic dysfunction in patients with CKD early and quantitatively.

Objective To explore the coronary flow reserve(CFR)in patients with coronary slow flow(CSF)and the diagnostic value of non-invasive myocardial work indices derived from echocardiography for CSF.Methods A retrospective study was conducted on 65 patients who underwent coronary angiography at the Zhongshan Hospital(Xiamen Branch),Fudan University due to angina pectoris,coronary artery risk factors,or electrocardiographic abnormalities from August 2020 to November 2023.Patients were divided into two groups based on the corrected TIMI frame count(cTFC):the CSF group(n=35)and the normal coronary blood flow velocity group(control group,n=30).Both groups underwent an adenosine triphosphate(ATP)drug load test to measure their coronary flow reserve(CFR).Conventional indices and myocardial work indices via echocardiography and two-dimensional speckle-tracking imaging(2D-STI)were acquired:left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),left ventricular ejection fraction(LVEF),E/e'ratio,global longitudinal strain(GLS),global constructive work(GCW),global wasted work(GWW),global work index(GWI),and global work efficiency(GWE).Receiver operating characteristic(ROC)curves were used to evaluate the diagnostic value of myocardial work indices for CSF.Results There was no significant difference in CFR values between the two groups,but the proportion of CSF group with CFR less than 2 was higher than that of the control group(P=0.023).Compared with the control group,the CSF group showed significantly lower levels of GLS,GWI,and GCW(P＜0.05).ROC curve analysis revealed that the GLS diagnostic threshold for CSF was-19.5%,with a sensitivity of 64.7%,specificity of 78.6%,and AUC of 0.793.Among the myocardial work indices,the AUC of GWI was the highest(0.825),with a sensitivity of 88.2% and specificity of 75.0% .Conclusions Some CSF patients retain coronary microcirculatory blood flow reserve function,but the proportion of patients with reduced CFR function is increasing.The left ventricular myocardial work indices can identify early myocardial work abnormalities and monitor myocardial ischemic damage in CSF patients.

The acute combination fractures of the atlas and axis in adults have a higher rate of neurological injury and early death compared with atlas or axial fractures alone. Currently, the diagnosis and treatment choices of acute combination fractures of the atlas and axis in adults are controversial because of the lack of standards for implementation. Non-operative treatments have a high incidence of bone nonunion and complications, while surgeries may easily lead to the injury of the vertebral artery, spinal cord and nerve root. At present, there are no evidence-based Chinese guidelines for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults. To provide orthopedic surgeons with the most up-to-date and effective information in treating acute combination fractures of the atlas and axis in adults, the Spinal Trauma Group of Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field of spinal trauma to develop the Evidence-based guideline for clinical diagnosis and treatment of acute combination fractures of the atlas and axis in adults ( version 2023) by referring to the "Management of acute combination fractures of the atlas and axis in adults" published by American Association of Neurological Surgeons (AANS)/Congress of Neurological Surgeons (CNS) in 2013 and the relevant Chinese and English literatures. Ten recommendations were made concerning the radiological diagnosis, stability judgment, treatment rules, treatment options and complications based on medical evidence, aiming to provide a reference for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults.
