Health economics evidence plays an important role in linking clinical value evidence with health resource allocation decisions in the development of clinical practice guidelines. It can not only effectively balance clinical effectiveness and economic feasibility but also avoid forming "idealized" recommendations that are detached from the affordability of the healthcare system or the burden-bearing capacity of patients. To promote guideline developers to use health economics evidence more standardizedly and fully, this paper conducts an in-depth analysis of the current application status, existing challenges, access channels, and application processes of health economics evidence in current guidelines, and on this basis, puts forward considerations and suggestions for strengthening and standardizing the application of health economics evidence in China's clinical practice guidelines.

Cancer is one of the most lethal and burdensome diseases worldwide. Its progression not only causes irreversible damage to the body, but also imposes a substantial psychological burden on patients due to its complex prognosis. Immune imbalance, a hallmark of the tumor microenvironment (TME), accelerates tumor invasion and metastasis by impairing the function of effector immune cells, promoting the abnormal infiltration of immunosuppressive cells, and disrupting cytokine homeostasis, thereby constituting a major barrier to the efficacy of cancer immunotherapy. Compared with conventional chemotherapy and radiotherapy, aerobic exercise has shown considerable potential in antagonizing tumor progression through relatively mild but effective immunomodulatory mechanisms. On the one hand, regular aerobic exercise enhances the number and activity of key effector immune cells, such as CD8⁺ T cells, thereby strengthening their ability to recognize and eliminate tumor cells and alleviate immune imbalance. On the other hand, aerobic exercise promotes tumor vascular normalization, improves vascular maturity, and stimulates the secretion of irisin and other anti-inflammatory myokines, thereby remodeling the TME and relieving its immunosuppressive state to delay tumor progression. However, psychological stress following a cancer diagnosis can not only act as an independent disruptive factor that exacerbates immune imbalance within the TME, but also amplify the effects of other detrimental factors, such as reduced treatment adherence, thereby further weakening the antagonistic effect of aerobic exercise on tumor growth. Psychological stress, as a chronic stressor, promotes the excessive secretion of emotion-related hormones, including glucocorticoids (GCs) and norepinephrine (NE), which further suppress the activation and effector functions of antitumor immune cells such as CD8⁺ T cells and natural killer (NK) cells, while facilitating the recruitment of protumor immune cells such as regulatory T cells (Tregs). These changes ultimately disrupt immune homeostasis in the TME, promote tumor immune evasion, accelerate tumor invasion and metastasis, and offset the beneficial effects of aerobic exercise on tumor control. In addition, psychological stress induces hyperactivation of the hypothalamic-pituitary-adrenal (HPA) axis and abnormal excitation of the sympathetic nervous system (SNS), thereby maintaining elevated levels of GCs, NE, and related stress hormones, suppressing inflammatory chemokine expression and immune cell recruitment, and further disturbing immune homeostasis in the TME, which accelerates tumor progression. More importantly, prolonged psychological stress can also disrupt the homeostasis of central neurotransmitters, such as 5-hydroxytryptamine (5-HT) and glutamate (Glu). This not only directly inhibits the activation and effector functions of antitumor immune cells and promotes the establishment of an immunosuppressive microenvironment, but also impairs cellular energy metabolism and continuously provides energy for tumor cells through metabolic reprogramming, thereby sustaining rapid tumor growth and adaptation to a hostile TME. Ultimately, these alterations contribute to the dysregulation of “neuro-endocrine-immune” axis and weaken the protective effect of aerobic exercise against tumor progression. Therefore, this review focuses on the interaction between psychological stress and the “neuro-endocrine-immune” axis, with particular emphasis on the mechanisms by which psychological stress induces immune imbalance and weakens the antagonistic effect of aerobic exercise on tumor progression. We further highlight the important role of psychological stress in tumor progression and propose that combining psychotropic interventions, aerobic exercise, and clinical antitumor immunotherapy may help restore the tumor-killing capacity of the immune system. Such a multimodal strategy may exert synergistic effects at multiple levels, including psychological stress relief, neuroendocrine regulation, and reconstruction of immune homeostasis, thereby providing new perspectives for identifying therapeutic targets in solid tumors, enhancing the efficacy of cancer immunotherapy, and improving patient prognosis.

Objective:To investigate the impact of preoperative biliary drainage (PBD) on early postoperative outcomes in patients undergoing pancreaticoduodenectomy (PD) for malignant obstructive jaundice of varying severity.Methods:Clinical data of 346 patients who underwent PD at the Second Hospital of Lanzhou University between January 2019 and December 2024 were retrospectively analyzed, including 229 males and 117 females, aged (62.2±8.9) years. Pathological diagnoses included pancreatic malignancy (121 cases, 35.0%), bile duct malignancy (128 cases, 37.0%), duodenal malignancy (76 cases, 22.0%), and ampullary malignancy (21 cases, 6.0%). Based on a preoperative total bilirubin cutoff of 171 μmol/L, patients were stratified into a mild jaundice group ( n=133, total bilirubin <171 μmol/L) and a moderate-to-severe jaundice group ( n=213, total bilirubin ≥171 μmol/L). Each group was further divided into PBD and non-PBD subgroups. After propensity score matching, 36 pairs were matched in the mild jaundice group and 30 pairs in the moderate-to-severe jaundice group. Intraoperative blood loss, operation time, R 0 resection rate, postoperative complications (pancreatic fistula, bile leakage, postoperative hemorrhage, etc.), severe complications (Clavien-Dindo grade Ⅲ or above), total hospital stay, and total hospitalization costs were compared between the PBD and non-PBD groups. Results:In both the mild and moderate-to-severe jaundice groups, no statistically significant differences were observed between the PBD and non-PBD groups regarding intraoperative blood loss, operation time, or R 0 resection rate (all P>0.05). In the mild jaundice group, the total hospital stay [28.5 (24.0, 37.5) days] and total hospitalization costs [9.4 (7.8, 10.8) wanyuan] in the PBD group were significantly higher than those in the non-PBD group [22.0 (19.0, 29.0) days and 8.1 (7.0, 10.2) wanyuan, respectively)] ( Z=3.94, P<0.001; Z=2.25, P=0.025). In the moderate-to-severe jaundice group, the total hospital stay in the PBD group [28.5 (24.8, 36.0) days] was significantly longer than that in the non-PBD group [21.5 (20.8, 30.8) days] ( Z=2.68, P=0.007). The overall incidence of postoperative complications did not differ significantly between the PBD and non-PBD groups in either jaundice severity cohort (all P>0.05). However, in the moderate-to-severe jaundice group, the incidence of severe complications in the PBD group (16.7%, 5/30) was significantly lower than that in the non-PBD group (43.3%, 13/30) ( χ2=5.08, P=0.024). Conclusion:PBD brought no significant benefit in patients undergoing PD with mild jaundice but increased the financial burden, which may recommended for routine use. In patients undergoing PD with moderate-to-severe jaundice, PBD helped reduce severe complications despite a prolonged hospitalization. which is recommended after comprehensive evaluation.

Objective:To report the follow-up status of patients participating phase Ⅲ clinical trial (ZGDD3) of Donafenib tosilate (abbreviated as Donafenib) in the treatment of progressive radioactive iodine-refractory differentiated thyroid cancer (RAIR-DTC), and to explore its efficacy, safety and prognostic factors.Methods:This study was a randomized controlled trial, and the clinicopathological data and follow-up results of 29 patients (16 males, 13 females, age 40-68 years) who participated in the clinical trial ZGDD3 between August 2018 and March 2021 were analyzed. Patients were divided into Donafenib group and placebo group using the central dynamic randomization method with the ratio of 2∶1. Adverse reactions (AE) during the trial were observed. Independent-sample t test, Mann-Whitney U test and Fisher exact test were used to analyze the differences of baseline characteristics between the two groups. Progression-free survival (PFS) and overall survival (OS) were followed up. Kaplan-Meier method was used to draw the survival curve (log-rank test) and Cox regression analysis was used to analyze the prognostic factors. Results:There were 22 patients in Donafenib group and 7 patients in placebo group. There were no significant differences of baseline characteristics between the two groups ( t values: -0.68, Z values: from -1.47 to -0.56, all P>0.05). The follow-up was 32.07(21.07, 49.85) months. During the trial, drug-related AEs occurred in all patients in Donafenib group, mostly was grade Ⅰ-Ⅱ, no grade Ⅳ or Ⅴ AEs were found. The median PFS was significantly longer in Donafenib group than that in placebo group (13.23 vs 4.03 months; χ2=9.68, P=0.002), and the median OS was 55.00 and 24.30 months respectively ( χ2=2.07, P=0.150). Metastasis to less common sites was the independent risk factor for OS (hazard ratio ( HR)=6.789, 95% CI: 1.272-36.246, P=0.025). Conclusions:Donafenib shows good clinical application in the treatment of RAIR-DTC, demonstrating good safety and efficacy. Metastasis to less common sites is closely related to OS.

Objective:To evaluate the efficacy and safety of telitacicept in the treatment of systemic lupus erythematosus (SLE) .Methods:The clinical data of 25 SLE patients who received standard therapy combined with telitacicept at the Department of Dermatology, Xiangya Second Hospital, Central South University, from 2021 to 2024 were retrospectively collected. Baseline demographic and clinical characteristics were analyzed. Changes in skin lesions, joint pain symptoms, complete blood count, and biochemical parameters at 4, 12, and 24 weeks of treatment were compared with baseline (week 0). The Wilcoxon signed-rank test was used to compare complement C3 and C4 levels before and after treatment, and univariate logistic regression analysis was performed to explore factors influencing the efficacy of telitacicept.Results:Among the 25 SLE patients, 3 were male (12.0%) and 22 were female (88.0%). Based on the SLE Disease Activity Index (SLEDAI) -2000 scores, 8 patients were mild, 13 were moderate, and 4 were severe. Of the 11 SLE patients with rashes before treatment, 6 achieved complete remission at 12 weeks. Among the 7 patients with joint pain before treatment, 4 experienced symptom resolution at 24 weeks. The proportion of patients with leukopenia at baseline and at 4, 12, and 24 weeks was 10/25 (40.0%), 0/24 (0), 1/22 (4.5%), and 2/19 (10.5%), respectively. The proportion of patients with thrombocytopenia was 6/25 (24.0%), 3/24 (12.5%), 1/22 (4.5%), and 1/19 (5.3%), respectively, and the proportion of patients with anemia was 7/25 (28.0%), 3/24 (12.5%), 1/22 (4.5%), and 1/19 (5.3%), respectively. At baseline, 11 out of 25 patients (44.0%) had proteinuria. At 12 weeks, the urinary protein quantification level (0.4 [0, 0.6] g/L) was significantly lower than at baseline (0.9 [0.8, 1.2] g/L). The SLE responder index-4 (SRI4) response rates at 4, 12, and 24 weeks were 14/18, 15/17, and 12/14, respectively. Complement C3 and C4 levels were significantly higher at 4, 12, and 24 weeks compared to baseline (all P < 0.001). Univariate logistic regression analysis showed that age, disease duration, glucocorticoid dosage, baseline complement C4 levels, antinuclear antibody titer, and SLEDAI-2K score did not significantly affect the efficacy of telitacicept (SRI4 response rate at 12 weeks) (all P > 0.05). No serious adverse reactions related to telitacicept were observed in patients. Conclusions:Telitacicept improved skin lesions, complement C3 and C4 levels, and anti-double-stranded DNA antibody levels in SLE patients. No association was found between the efficacy of telitacicept and baseline SLEDAI-2K scores, antinuclear antibody titers, or complement C4 levels, suggesting that telitacicept is an effective and safe treatment for SLE patients.

Objective:To analyze differences on characteristics of HIV/AIDS knowledge, beliefs and behavior among female college students who reported having sex in Zhejiang Province between 2018 and 2020, and provide reference for HIV/AIDS prevention and control among female college students.Methods:Cross-sectional surveys were conducted in October-November 2018 and November-December 2020 among female college students in 13 universities in 11 cities in Zhejiang Province, and female college students who self-reported having sexual intercourse in the past year were included as study subjects, with sample size estimates of 5 265 and 9 466 for the two surveys, respectively. The factors related to the change of relevant characteristics of the two survey subjects were analyzed. The χ2 test was used for univariate analysis and logistic regression model was used for multivariate analysis.Statistical analyses were performed with SPSS 23.0 software. Results:Of the 17 354 and 20 675 female college students surveyed in 2018 and 2020, respectively, the proportion who self-reported having had sex in the past year was 6.56% (1 139/17 354) and 4.19% (866/20 675). Multivariate logistic regression analysis showed that compared with female college students in 2018, the students who have sexual behaviour, receiving health education class by their university in the past year (a OR=1.57, 95% CI:1.29-1.91), receiving HIV testing promotion by the university in the past year (a OR=2.59,95% CI:2.13-3.14), receiving self-assessment of HIV risk by the university in the past year (a OR=2.97,95% CI:2.43-3.65), high self-efficacyfor condom use (a OR=2.00, 95% CI:1.66-2.41), receiving voluntary counseling and HIV testing (VCT) (a OR=1.81,95% CI: 1.41-2.87), perceived risk of HIV infection (a OR=2.44, 95% CI:1.32-4.54), using condoms whenever having casual sexual behaviour in the past year (a OR=3.35,95% CI:1.66-6.77) were significantly higher in 2020. Conclusions:Compared with female college students in 2018, the proportion of female college students who self-reported sexual activity decreased slightly in 2020, and the proportion of receiving HIV/AIDS lectures or health education classes, the proportion of self-rated at risk of HIV infection, the proportion of receiving VCT, the proportion of using condoms with very high confidence in self-efficacy and condom use had an increased.

OBJECTIVE: To explore clinical efficacy of different technical combinations in treating ischemic diabetic foot (DF). METHODS: A retrospective analysis was conducted on 35 patients with DF who were treated with vascular interventional opening technique, periosteal distraction technique and bone cement coverage technique from January 2024 to November 2024. They were divided into comprehensive group and periosteal distraction group according to whether the vascular interventional opening technique was used in combination or not. There were 5 patients in comprehensive group, including 4 males and 1 female, aged from 59 to 73 years old with an average of (64.40±5.46) years old;the duration of diabetes ranged from 0.17 to 30.00 years with an average of (14.63±12.02) years;the courses of DF ranged from 30 to 150 days with an average of (84.00±61.48) days;2 patients were grade 2, 2 patients were grade 3, and 1 patient was grade 4 according to Wagner classification;combined vascular interventional opening, periosteal distraction and bone cement coverage surgery for treatment. There were 30 patients in periosteal stretch group, including 22 males and 8 females, aged from 58 to 86 years old with an average of (72.63±7.84) years old;the duration of diabetes was 10.00 (6.75, 16.75) years;the courses of DF was 30.00 (15.00, 37.50) days;14 patients were grade 2, 11 patients were grade 3, and 5 patients were grade 4 according to Wagner classification; combined periosteal distraction and bone cement coverage surgery for treatment. Changes of C-reactive protein (CRP), interleukin-6 (IL-6), and procalcitonin (PCT), toe skin temperature, peripheral capillary oxygen saturation (SpO₂), and visual analogue scale (VAS) for pain were compared between two groups before operation and 1 week after operation. The number of operations, healing period, healing number, toe amputation number, preoperative fever situation and the number of complications were compared between two groups. RESULTS: Both groups were followed up for at least 6 months. There were no statistically significant differences in the number of operations, healing period, toe amputation rate, wound healing rate and complications between two groups (P>0.05). Before operation, the toe skin temperature of comprehensive group (26.98±0.88) ℃ was lower than that of periosteal distraction group (28.17±1.45) ℃, and the difference was statistically significant (P<0.05);while there were no statistically significant difference in CRP, IL-6, PCT, toe SpO2 and VAS between two groups (P>0.05). At 1 week after operation, IL-6, toe skin temperature, toe SpO₂ and VAS in comprehensive group were 12.29(7.92, 22.15) pg·ml-1, (36.02±0.23) ℃, (95.80±0.84) % and(1.40±0.55) respectively, while those in periosteal distraction group were 5.49(4.36, 7.45) pg·ml^-1, (31.36±1.57) ℃, (84.53±6.38) %, (2.20±0.81);and there were statistically significant differences between two groups(P<0.05). CRP, IL-6 and VAS at 1 week after operation in both groups were decreased compared with those before operation, and the differences were statistically significant(P<0.05). The toe skin temperature and SpO₂ were increased compared with those before operation, and the differences were statistically significant(P<0.001). CONCLUSION The multi-technique combination therapy, including vascular interventional opening technique, periostealdistraction technique and bone cement covering technique, could protect each other, enhance efficacy, effectively promote the wound healing of ischemic diabetic foot ulcer, and reduce the toe amputation rate. For moderate to severe ischemic DF, the combined use of periosteal distraction and bone cement coverage techniques has a satisfactory effect. For extremely severe ischemic DF with inflow tract lesions, vascular interventional opening techniques need to be added.

Objective To analyze the clinical characteristics of recipients with interstitial lung disease (ILD) who underwent second lung transplantation and summarize the diagnostic and therapeutic experience. Methods A retrospective analysis was conducted on the clinical data of 14 patients who underwent first and second lung transplants for ILD at the First Affiliated Hospital of Guangzhou Medical University from January 2015 to December 2024. The preoperative conditions, intraoperative events, postoperative treatments and prognoses of the first and second lung transplantation were compared, and the postoperative survival of ILD patients after the second lung transplantation was analyzed. Results Among the 14 recipients of the second lung transplant, 13 underwent the procedure due to chronic lung allograft dysfunction, and 1 due to airway complications. The median interval time from the first to the second lung transplant was 32 (2, 80) months. Before the second transplantation, 2 recipients required endotracheal intubation and mechanical ventilation, and 2 required endotracheal intubation, mechanical ventilation, and extracorporeal membrane oxygenation (ECMO) support. The surgical time for the second lung transplantation was longer than that for the first, with increased intraoperative red blood cell and plasma transfusion volumes, the proportion of ECMO support during the second lung transplantation was higher than that during the first (all P<0.05). However, the cold ischemia time for one-sided lung transplant completion in the first lung transplant was similar to that in the second lung transplantation (P>0.05). The median follow-up time after the second lung transplantation was 32 (1, 63) months. The 1-month, 6-month and 1-year survival rates after the second lung transplantation were 79%, 57% and 50%, respectively, with causes of death being infection, multiple organ failure and gastrointestinal bleeding. Conclusions For ILD patients undergoing second lung transplantation after the first lung transplantation, the second lung transplantation is more challenging, with longer surgical time and higher intraoperative blood loss. It requires higher surgical skills and perioperative management. Non-emergency second transplantation may still achieve good results.
