Objective To explore the safety and effects of alpha-lipoic acid (ALA) in patients with ischemic heart failure (IHF). Methods A randomized, double-blind, placebo-controlled trial was designed (ClinicalTrial.gov registration number NCT03491969). From January 2019 to January 2023, 300 patients with IHF were enrolled in four medical centers in China, and were randomly assigned at a 1∶1 ratio to receive ALA (600 mg daily) or placebo on top of standard care for 24 months. The primary outcome was the composite outcome of hospitalization for heart failure (HF) or all-cause mortality events. The second outcome included non-fatal myocardial infarction (MI), non-fatal stroke, changes of left ventricular ejection fraction (LVEF) and 6-minute walking distance (6MWD) from baseline to 24 months after randomization. Results Finally, 138 patients of the ALA group and 139 patients of the placebo group attained the primary outcome. Hospitalization for HF or all-cause mortality events occurred in 32 patients (23.2%) of the ALA group and in 40 patients (28.8%) of the placebo group (HR＝0.753, 95%CI 0.473-1.198, P＝0.231; Figure 1A-1C). The absolute risk reduction (ARR) was 5.6%, the relative risk reduction (RRR) associated with ALA therapy was approximately 19.4% compared to placebo, corresponding to a number needed to treat (NNT) of 18 patients to prevent one event. In the secondary outcome analysis, the composite outcome of the major adverse cardiovascular events (MACE) including the hospitalization for HF, all-cause mortality events, non-fatal MI or non-fatal stroke occurred in 35 patients (25.4%) in the ALA group and 47 patients (33.8%) in the placebo group (HR＝0.685, 95%CI 0.442-1.062, P＝0.091; Figure 1D). Moreover, greater improvement in LVEF (β＝3.20, 95%CI 1.14-5.23, P＝0.002) and 6MWD (β＝31.7, 95%CI 8.3-54.7, P＝0.008) from baseline to 24 months after randomization were observed in the ALA group as compared to the placebo group. There were no differences in adverse events between the study groups. Conclusions These results show potential long-term beneficial effects of adding ALA to IHF patients. ALA could significantly improve LVEF and 6MWD compared to the placebo group in IHF patients.

Objective:To analyze the curative effect of sandwich cheiloplasty for the treatment of macrocheilia secondary to port-wine stain (PWS).Methods:A total of 43 patients, including 20 males and 23 females, aged 37.0 years (ranged from 4 to 69 years), who underwent sandwich cheiloplasty for the treatment of macrocheilia secondary to PWS from March 2008 to March 2022 were retrospectively enrolled. According to the location of the lesions, they were divided into two groups: upper lip group (21 cases) and lower lip group (22 cases). Pathological examinations were performed in all excised specimens. Postoperative attentions should be paid to keeping incisions locally clean, observing the blood supplying, and taking care of fluid accumulation or incision split. After discharge, the lip appearance and function were evaluated every six months in the outpatient department, and the long-term efficacy was further divided into three levels: grade Ⅰ (poor), grade Ⅱ (moderate), and grade Ⅲ (good). The comparison of grade data named long-term efficacy between the two groups was conducted by Mann-Whitney U test.Results:All 43 patients underwent sandwich cheiloplasty, of which 40 patients received one operation, whereas the other 3 received two due to recurrences. One-stage incision healing was achieved in 43 cases, whereas partial mucosal necrosis appeared in 2 cases, and slight incision dehiscence occurred in 1 case, which healed well after local dressing change. The pathological examination results of 43 excised tissue specimens all showed capillary malformations. After follow-up for 1 to 10 years, long-term efficacy evaluation was made up as follows: 36 cases were evaluated as grade Ⅲ, 7 cases as grade Ⅱ, and 0 case as grade Ⅰ. There were 18 cases of grade Ⅲ, and 3 cases of grade Ⅱ in group A, compared to 18 cases of grade Ⅲ, and 4 cases of grade Ⅱ in group B. By rank sum test, there was no significant difference in overal efficacy between the two groups ( Z=0.342, P>0.05). Conclusions:Sandwich cheiloplasty for the treatment of macrocheilia secondary to PWS effectively removes malformed vascular lesions, and consequently, it can achieve a good long-term therapeutic effect.

Objective:To investigate the effect and adverse reactions of radiotherapy combined with targeted drugs for the treatment of multiple brain metastases (MBM) in patients with non-small cell lung cancer (NSCLC) and the changes in serum tumor marker levels.Methods:A retrospective cohort study was conducted. Eighty-six patients with NSCLC-MBM who were admitted to the Fifth People's Hospital of Datong from June 2019 to June 2022 were selected, and the patients were divided into the study group and the control group according to different treatment methods, with 43 cases in each group. The study group was given radiotherapy to the tumor primary focus combined with erlotinib or gefitinib targeted therapy, and the control group was given radiotherapy to the tumor primary focus based on conventional chemotherapy with pemetrexed combined with platinum-based drugs. The efficacy, overall survival rate and incidence of adverse reactions were compared between the two groups at 1 month after treatment; the levels of serum tumor markers S100-β, carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCCA) were compared between the two groups before and after treatment.Results:The study group was aged (55±5) years old, ranging from 39 to 75 years old, including 15 (34.88%) males and 28 (65.12%) females; the control group was aged (54±5) years old, ranging from 38 to 72 years old, including 17 (39.53%) males and 26 (60.47%) females. The general data such as age and gender of patients were compared between the two groups, and the differences were not statistically significant (all P>0.05). The objective remission rate [53.49% (23/43) vs. 32.56% (14/43)] and disease control rate [93.02% (40/43) vs. 69.77% (30/43)] at 1 month after treatment, and 1-year overall survival rate [58.14% (25/43) vs. 46.51% (20/43)] of the study group were higher than those of the control group, and the differences were statistically significant ( χ2 values were 10.91, 5.76 and 11.02, respectively; P values were 0.001, 0.016 and 0.001, respectively). Before treatment, the differences in serum S100-β, CEA and SCCA levels between the two groups of patients were not statistically significant (all P > 0.05). At 1 month after treatment, the serum S100-β, CEA and SCCA levels of the study group were lower than those of the control group, and the differences were statistically significant (all P < 0.05). The proportion of patients with adverse reactions in the study group was lower than that in the control group [13.95% (6/43) vs. 39.53% (17/43)], and the difference was statistically significant ( χ2 = 8.35, P < 0.05). Conclusions:Radiotherapy combined with targeted drugs therapy may prolong the survival of NSCLC-MBM patients, reduce the occurrence of adverse reactions and decrease the levels of serum tumor markers, which is worthy of clinical promotion.

Purpose: This systematic review aimed to scrutinize the progression of symptom cluster research in adult cancer patients who received primary or adjuvant chemotherapy between 2001 and 2023, providing a comprehensive understanding of clinical practice and future research. Methods: PubMed, Ovid MEDLINE, Excerpta Medica Database, Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, and Web of Science databases were searched for theme words and free words related to symptom clusters, cancer, and chemotherapy. Eligible studies were published between January 1, 2001, and May 30, 2023; adults who were diagnosed with cancer and received primary or adjuvant chemotherapy were evaluated. Results: Twenty-eight studies were included in this review. The Memorial Symptom Assessment Scale emerged as the predominant instrument and exploratory factor analysis was the most frequently employed statistical method to identify symptom clusters. Psychological, gastrointestinal, and physical image symptom clusters were the most commonly delineated. Furthermore, the temporal stability of the symptom clusters showed varying dynamics, with psychological symptom clusters displaying relative consistency over time. Conclusion Interventions are needed for the most common and stable symptoms in patients with cancer undergoing chemotherapy. Future endeavors may necessitate more longitudinal studies to delve deeper into the temporal stability and dynamic variations of symptom clusters. Such investigations hold promise for advancing symptom cluster research, elucidating the underlying mechanisms, and fostering the development of targeted interventions, thereby enriching the symptom management paradigm in oncological care.
