Objective:To explore the characteristics of attention bias and the role of embodied emotion prim-ing in college students with different traits of anxiety.Methods:From 2 310 college students,28 from low trait anxi-ety group and 30 from high trait anxiety group were selected based on the scores of the Trait Anxiety Scale.The at-tention bias index,attention orientation index and attention detachment difficulty index were calculated by point de-tection experiment.By asking two groups of subjects to change their body posture to induce embodied emotion,and then responding to the location of the detection point,the effects of embodied emotion priming on the attention bias of college students with different traits of anxiety were investigated.Results:The point detection experiment found that the attention detachment difficulty index of negative emotional faces in the high trait anxiety group was signifi-cantly greater than 0,and the attention orientation index of positive emotional faces in the low trait anxiety group was significantly greater than 0(Ps＜0.05).The attention bias index for positive emotional faces in low trait anxie-ty group was significantly higher than that in high trait anxiety group(P＜0.05).Under embodied negative prim-ing,the attention bias index of negative emotional faces in low trait anxiety group was significantly greater than 0(P＜0.05).The attention orientation indices of negative emotional faces were significantly higher than that of posi-tive emotional faces in both groups(P＜0.05).Conclusion:College students with high trait anxiety have difficulty in escaping attention to negative faces,while those with low trait anxiety have accelerated attention orientation to positive emotional faces.Embodied negative priming may have a greater impact onattention bias of towards negative emotional faces in students with low trait anxiety.

In recent years,a growing body of research has demonstrated that acupuncture can be used to effectively treat a diverse range of diseases,including functional gastrointestinal disorders,cardiovascular diseases,as well as anxiety and depression,through the modulation of the paraventricular hypothalamic nucleus(PVN).Acupuncture may exert its therapeutic effect either by modulating specific neurons within the PVN,such as corticotropin releasing hormone(CRH)neurons,or by regulating the release of hormones,such as oxytocin(OXT)and vasopressin(VP),and the activity of neural circuits associated with the PVN.This review summarizes the mechanisms by which PVN is involved in acupuncture treatment,including its regulatory mechanisms in gastrointestinal diseases,cardiovascular diseases,and negative emotions and pain.Future research should be conducted to further explore the precise mechanisms by which acupuncture regulates PVN to treat diseases,focusing on clarifying the specific processes of signaling pathway transduction,and exploring the specific effects of acupunture of different acupoint combinations and stimulation frequencies and intensity on PVN.

Objective:To assess the efficacy and safety profile of antaitasvir phosphate combined with yiqibuvir in the treatment of chronic hepatitis C (CHC) of various genotypes, without cirrhosis or with compensated cirrhosis.Methods:394 cases with CHC from 22 centers were collected from October 2021 to April 2023. They were randomly assigned to receive either the experimental drugs (antaitasvir phosphate 100 mg+yiqibuvir 600 mg) or placebo treatment in a 3∶1 ratio. The patients were administered drugs once a day for 12 consecutive weeks, and then followed up for 24 weeks after treatment cessation. All subjects were unblinded at the four-week follow-up following drug discontinuation, with the experimental drug group continuing to complete subsequent post-discontinuation follow-up. The placebo group was switched to receive the experimental drugs for a repeated 12-week treatment period and followed up for another 24 weeks after discontinuation of the drug (placebo delayed treatment phase).The sustained virologic response rate (SVR12) was observed for subjects in the double-blind phase and the placebo delayed-treatment phase at 12 weeks after treatment cessation.Virological resistance analysis was performed on subjects who failed treatment. The primary efficacy endpoint was SVR12. The number and percentage of subjects who achieved "HCV RNA

Objective:This study aimed to investigate the association between early immune reconstitution and Epstein-Barr virus (EBV) reactivation by analyzing changes in natural killer (NK), B, and T cells and their functional status in the peripheral blood during the early post-transplant period.Methods:This study included 23 patients who underwent haplo-hematopoietic stem cell transplantation (HSCT). The immune reconstitution of NK cells, T cells, and B cells as well as the expression levels of NK and T cell exhaustion markers (PD-1, TIM-3, and CTLA-4) and cytotoxic function at 1, 2, and 3 months post-transplantation were compared between patients with EBV activation (EBV+ group) and those without activation (EBV- group) post- transplantation.Results:EBV activation occurred in nine patients post-transplantation (EBV+ group), whereas 14 patients demonstrated no activation (EBV- group). All patients with EBV activation exhibited EBV viremia, and no EBV-associated diseases occurred. No significant differences in the clinical characteristics were found between the two groups of patients. The median proportion of CD3 +CD8 + T cells in the EBV+ group was significantly lower than that in the EBV- group at 1 month post-transplantation ( P=0.033). The median proportion of the CD3 -CD16 negCD56 bri subset in the EBV+ group was significantly higher than that in the EBV- group at 2 months post-transplantation ( P=0.046). No significant differences in the median proportions of CD3 -CD19 + B cells were observed between the two groups at 1, 2, and 3 months post-transplantation. The expression of CTLA-4 on CD3 -CD16 briCD56 dim NK cells in the EBV+ group was significantly higher than that in the EBV- group at 1 month post-transplantation ( P=0.033). The expression of TIM-3 on CD3 +CD8 + T cells in the EBV+ group was significantly higher than that in the EBV- group ( P=0.009). The expression level of TIM-3 on CD3 -CD16 negCD56 dim NK cells in the EBV+ group was significantly lower than that in the EBV- group at 2 months post-transplantation ( P=0.023). The expression levels of TIM-3 on CD3 +CD4 + T cells in the EBV+ group than those in the EBV- group at 1 and 3 months post-transplantation ( P=0.002, P=0.043). The median positive rate of Granzyme B expression in CD3 +CD8 + T cells and CD3 +CD4 + T cells in the EBV+ group was significantly lower than that in the EBV- group at 1-month post-transplantation ( P=0.033, P=0.016). The median positive rate of Granzyme B expression in the CD3 -CD16 briCD56 neg cell subset in the EBV+ group was higher than that in the EBV- group at 2 months post-transplantation ( P=0.012). The median positive rate of Granzyme B expression in CD3 +CD4 + T cells in the EBV+ group remained significantly lower than that in the EBV- group at 2 months post-transplantation ( P=0.049). The median positive rate of perforin expression in the CD3 -CD16 briCD56 dim cell subset was significantly higher in the EBV+ group than in the EBV- group at 3 months post-transplantation ( P=0.003). The median positive rate of IFN-γ expression in CD3 +CD8 + T cells in the EBV+ group was significantly lower than that in the EBV- group at 3 months post-transplantation ( P=0.036) . Conclusion:Delayed NK cell and T lymphocyte reconstitution, high exhaustion marker expression, and weakened cytotoxic functions may be related to EBV reactivation after haploidentical HSCT.

Objective:To evaluate the efficacy and safety of antaitasvir phosphate 100 mg or 200 mg combined with yiqibuvir for 12 weeks in patients with various genotypes of chronic hepatitis C, without cirrhosis or compensated stage cirrhosis.Methods:Patients with chronic hepatitis C (without cirrhosis or compensated stage cirrhosis) were randomly assigned to the antaitasvir phosphate 100 mg+yiqibuvir 600 mg group (100 mg group) or the antaitasvir phosphate 200 mg+yiqibuvir 600 mg group (200 mg group) in a 1∶1 ratio. The drugs were continuously administered once a day for 12 weeks and observed for 24 weeks after drug withdrawal. The drug safety profile was assessed concurrently with the observation of the sustained virological response (SVR12) in the two patient groups 12 weeks following the drug cessation. The intention-to-treat concept was used to define as closely as possible a full analysis set, including all randomized cases who received the experimental drug at least once. The safety set was collected from all subjects who received the experimental drug at least once (regardless of whether they participated in the randomization group) in this study. All efficacy endpoints and safety profile data were summarized using descriptive statistics. The primary efficacy endpoint was SVR12. The primary analysis was performed on a full analysis set. The frequency and proportion of cases were calculated in the experimental drug group (antaitasvir phosphate capsules combined with yiqibuvir tablets) that achieved "HCV RNA

ObjectiveTo construct the mental health benefits of physical activity of Tai Chi and framework for college students based on International Classification of Functioning, Disability, and Health (ICF), and to systematically review the effect of physical activity of Tai Chi on anxiety, depression and sleep quality of college students. MethodsRelevant literatures about the health outcomes on anxiety, depression and sleep quality of college students participating in physical activity of Tai Chi were retrieved from databases of Web of Science, PubMed, Medline, Scopus, CNKI, Wanfang data, from the establishment to November 10th, 2022, and screened and reviewed. ResultsTen randomized controlled trials were included finally, from China and U.S.， involving 960 participants (aged 16.4 to 40 years). The main sources were from journals about physical activity and health, with publication dates from 2016 to 2021. The quality of the included literatures was evaluated using the Physical Therapy Evidence Database (PEDro) scale with a mean score of 6.3. The main mental health problems of college students mainly focused on depression, anxiety, high stress, and poor sleep quality. The physical activity of Tai Chi included 24 simplified Tai Chi and Chen style Tai Chi. The frequency of physical activity of Tai Chi was mainly 1 to 6 times a week, 45 to 90 minutes (60 minutes mostly) a time, for 4 to 18 weeks. The health benefits of Tai Chi on anxiety, depression, and sleep quality for college students in the ICF were mainly in the affective function (b152), psychomotor function (b147), energy and drive function (b130), and sleep function (b134). The beneficial outcomes of physical activity of Tai Chi involved reducing anxiety, alleviating depressive symptoms and reducing stress. Compared with physical activity of Tai Chi, physical activity of Tai Chi with the addition of a twenty-four-pattern Taijiquan theory course was more effective in improving depression levels in patients with mild and moderate depression. Tai Chi also can help to improve sleep quality, shorten the time to sleep, and reduce sleep disturbances and daytime dysfunction. ConclusionA PICO framework of Tai Chi for the health benefits of college students has been constructed using ICF. Tai Chi engaged in by college students are mainly 24 simplified Tai Chi. The frequency of physical activity of Tai Chi is 45 to 90 minutes (60 minutes mostly) a time, 1 to 6 times a week, for 4 to 18 weeks. The physical activities of Tai Chi can benefit in reducing anxiety and depression of college students and improving the quality of sleep.

Objective:To explore the clinical effect of X-N advancement flap in repairing pressure ulcer on the buttock or back.Methods:From June 2018 to June 2019, 20 patients with grade Ⅳ pressure ulcers on the buttock or back were hospitalized and treated in the Department of Traumatology, Burns and Plastic Surgery of Fourth Affiliated Hospital of Guangxi Medical University, including 15 males and 5 females, aged 48-89 years. The area of the patient′s wound was 8 cm×5 cm-15 cm×12 cm after debridement, and all were repaired with the X-N advancement flap designed by the author. The flap was designed according to the direction of skin relaxation on both sides of the wound, and the skin was incised in X-shape and sutured in N-shape. The width and advancement distance of the flap were recorded, and the ratio of the advancement distance to the width of the flap was calculated. The flap survival, complication, and follow-up were observed and recorded.Results:The width of the flap was (5.9±1.2) cm, the advancement distance of the flap was (10.3±2.5) cm, and the ratio of the advancement distance to the width of the flap was 1.8±0.4. All the flaps survived, and none of the flaps had blood flow disorder. Local dehiscence occurred in the flap of one patient 1 week after surgery, which was healed after laying on the floating bed, strengthened care, and wound dressing change. The flap of one patient developed infection 5 days after surgery, which was healed after partial suture removal, smooth drainage, and replacement with sensitive antibiotics. The wounds of the remaining 18 patients were all cured. After 3 months of follow-up, the flaps survived well with good elasticity and texture.Conclusions:The X-N advancement flap can make the skin and soft tissue move forward effectively. It is simple and effective to repair pressure ulcers on the back or buttock of patients with this flap, which is worthy of clinical promotion and application.
