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.

Recent studies have demonstrated that the malignant proliferation and continuous progression of lymphoma are highly dependent on enhanced lipid metabolism. Consequently, targeting lipid metabolism pathways have emerged as a promising direction for lymphoma treatment. This paper reviews the fatty acid metabolism, cholesterol metabolism, and phospholipid metabolism in lymphoma, thereby providing novel insights for its therapeutic strategies.

Objective To observe the clinical efficacy of regulating conception vessel and unblocking governor vessel electroacupuncture in the treatment of cancer-related fatigue(CRF)of middle-to-advanced stage cervical cancer,and to explore its effect on inflammatory factors.Methods A total of 122 patients with a definitive diagnosis of CRF of middle-to-advanced stage cervical cancer admitted to the wards and outpatient clinics of Cangzhou Central Hospital from August 2021 to August 2023 were selected for the study.The patients were randomly divided into the control group and the observation group according to the random number table method,with 61 cases in each group.The patients in both groups were given conventional symptomatic treatments such as gastric protection and anti-vomiting since the day of action of chemotherapy.The control group was treated with Dexamethasone Tablets,and the observation group was treated with regulating conception vessel and unblocking governor vessel electroacupuncture on the basis of the control group,the course of treatment covered 21 days.After three weeks of treatment,the clinical efficacy of the two groups was evaluated.The changes in the traditional Chinese medicine(TCM)syndrome scores,Piper's Fatigue Scale(PFS)scores,Karnofsky Performance Status(KPS)scores,and Functional Assessment of Cancer Therapy-General(FACT-G)scores of the patients in the two groups before and after treatment were observed.The changes in interleukin 6(IL-6),hypersensitive C-reactive protein(hs-CRP),tumor necrosis factor α(TNF-α),and T-lymphocyte subsets indicators[CD3+,CD4+,CD8+,CD4+/CD8+]were compared between the patients in the two groups before and after treatment.Results(1)The total effective rate was 95.08%(58/61)in the observation group and 77.05%(47/61)in the control group.The efficacy of the observation group was superior to that of the control group,the difference being statistically significant(P<0.05).(2)After treatment,the TCM syndrome scores of patients in the two groups were significantly improved(P<0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P<0.05).(3)After treatment,the PFS scores of patients in the two groups were improved significantly(P<0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P<0.05).(4)After treatment,the serum IL-6,hs-CRP,and TNF-α levels of patients in the two groups were significantly improved(P<0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P<0.05).(5)After treatment,the CD3+,CD4+,CD8+,CD4+/CD8+of patients in the two groups were significantly improved(P<0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P<0.05).(6)After treatment,the KPS scores and FACT-G scores of patients in the two groups were significantly improved(P<0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P<0.05).Conclusion Regulating conception vessel and unblocking governor vessel electroacupuncture in the treatment of CRF of middle-to-advanced stage cervical cancer can effectively alleviate the fatigue of patients,inhibit the release of inflammatory factors,regulate the immune function,and improve the physical condition of patients,so as to improve the quality of life of patients.

BACKGROUND:Static stretching effectively improves joint motion amplitude,dynamic stretching effectively improves muscle strength and athletic performance through the post-activation strengthening effect of the muscles.OBJECTIVE:To explore the immediate effects of different stretching methods on knee joint muscle strength and vertical jump performance,and provide theoretical support for seeking the best stretching plan,improving sports performance,and preventing training injuries.METHODS:Thirty healthy college students were randomly recruited.The Biodex isokinetic muscle strength system,Qualisys infrared motion capture system,and AMTI three-dimensional force measurement platform were used to collect knee joint muscle strength and vertical jump data after static quadriceps/hamstring stretching,dynamic quadriceps/hamstring stretching,dynamic quadriceps/static hamstring stretching,and static quadriceps/dynamic hamstring stretching.The peak torque,average power,vertical jump height,peak vertical ground reaction force,and joint motion amplitude of the knee joint were used to evaluate the muscle strength and vertical jump performance of the knee joint.RESULTS AND CONCLUSION:Compared with the static quadriceps/hamstring stretching,dynamic quadriceps/hamstring stretching significantly increased knee joint peak torque,average power,and vertical jump height(P<0.05);dynamic quadriceps/static hamstring stretching and static quadriceps/dynamic hamstring stretching significantly increased knee extension and flexion peak torque and average power(P<0.05).Compared with static quadriceps/hamstring stretching,second peak vertical ground reaction force significantly decreased after static quadriceps/dynamic hamstring stretching(P<0.05);lower limb joint motion amplitude significantly increased after dynamic quadriceps/hamstring stretching(P<0.05).These findings indicate that immediate agonists/antagonistic muscle dynamic stretching and agonists dynamic stretching/antagonistic muscle static stretching significantly improve knee joint muscle strength,vertical jump performance,and joint motion amplitude.A larger joint motion amplitude is beneficial for improving athletic performance and better absorbing ground impact during landing.At the same time,agonists muscle dynamic stretching/antagonistic muscle static stretching is better than agonists/antagonistic muscle dynamic stretching to improve knee joint muscle strength,and agonists muscle static stretching/antagonistic muscle dynamic stretching is beneficial for improving the energy absorption capacity during vertical jumping and reducing the risk of injury during landing.

Objective:We genetically modified our non-replicating vaccinia virus NTV to improve its immunogenicity.Methods:We constructed NTV-modified strain NTV-ΔF1L-C7L by homologous recombination of vaccinia virus based on CRISPR-Cas9 technology by inserting the C7L gene while deleting the F1L gene. The recombinant virus NTV-ΔF1L-C7L was then immunized with 10 7 PFU in BALB/c mice, and the levels of humoral and cellular immunity induced by NTV-ΔF1L-C7L were detected by ELISA and ELISpot method, respectively, and the levels of neutralizing antibodies were determined by the phage-reduced neutralization assay. Results:The PCR and western- blot identification proved that the F1L gene of the constructed NTV-modified strain NTV-ΔF1L-C7L was missing, while the C7L gene was inserted back in the region, and the C7L gene could be expressed normally, indicating that the recombinant virus was constructed correctly. After immunization of mice with NTV-ΔF1L-C7L, ELISA result showed that the recombinant virus NTV-ΔF1L-C7L induced a higher level of IgG antibody than NTV; ELISpot result also showed that the recombinant virus was able to induce a higher level of IFN-γ; and the result of plaque reduction neutralization test showed that the recombinant virus was able to induce a higher level of IFN-γ antibody than that of NTV.Conclusions:We correctly constructed the NTV gene-modified strain NTV-ΔF1L-C7L, which induced stronger humoral and cellular immunity compared with NTV, and provided reference data for the research and development of replacement products for smallpox or monkeypox vaccines.
