This article combined the pathogenic characteristics of "latent wind" with the theory of collateral diseases to clarify the pathological features of tumor blood vessels, including their active proliferation, high permeabi-lity, and promotion of metastasis. The theory framework of "latent wind in collaterals" as the tumor mechanism was proposed, which suggests that at the site of tumor lesions, the collaterals inherit the nature of latent wind to grow excessively, adopt an open and discharge nature to leak essence, and tumor toxins, characterized by their rapid movement and frequent changes, spread and metastasize, driving the progression of malignant tumors. Focusing on the fundamental pathogenesis of "latent wind in collaterals", specific clinical treatment principles and methods centered on treating wind are proposed, including regulating qi and dispelling wind, clearing heat and extinguishing wind, unblocking collaterals and expelling wind, and reinforcing healthy qi to calm wind, so as to provide references for enhancing the precision of traditional Chinese medicine in treating malignant tumors.

BACKGROUND:Titanium implants are widely used in clinical practice because of their high strength and good biocompatibility.However,during implantation,bacterial infection and tissue damage environment produce a large number of reactive oxygen species,which can easily lead to delayed tissue healing and surgical failure.Consequently,the development of titanium implants with antimicrobial and antioxidant properties becomes paramount. OBJECTIVE:Considering the potent antimicrobial attributes of copper ions and the remarkable antioxidant qualities of polyphenols,we proposed the fabrication of polyphenol-mediated copper ion coatings on titanium surfaces.These coatings were subsequently assessed for their in vitro antimicrobial and antioxidant properties. METHODS:Nanostructures were generated on the titanium surface using the alkali thermal method.The titanium was immersed in a solution containing tannic acid and copper ions to achieve polyphenol-mediated copper ion coatings.The surface morphology and water contact angle were detected.The loading and release of copper ions were examined using atomic absorption spectroscopy.Staphylococcus aureus was inoculated on the surface of pure titanium sheet(blank group),alkali heat treated titanium sheet(control group),and polyphenol mediated copper ion modified titanium sheet(experimental group)to observe the bacterial survival status.Osteoblast precursor cells MC3T3-E1 were co-cultivated on the surface of three groups of titanium sheets to assess their antioxidant properties and bioactivity. RESULTS AND CONCLUSION:(1)Scanning electron microscopy showed that the polyphenol-mediated copper ion modified titanium sheet had rod-like nanostructures and no cracks on the surface.The surface hydrophilicity of copper ion modified titanium sheet mediated by polyphenol was close to that of pure titanium sheet.Atomic absorption spectrometry results showed a 51%increase in the loading capacity of copper ions after polyphenol mediation,with a uniform release of copper ions.(2)The antibacterial rates of titanium sheets in the blank group,control group,and experimental group were 0%,21.65%,and 93.75%,respectively.The live/dead staining and CTC staining showed that the live bacteria on the surface of titanium plates in the blank group were the most,and the live bacteria on the surface of titanium plates in the experimental group were the least.(3)The results of live/dead staining and CCK-8 assay showed that the three groups of titanium sheets had good cytocompatibility,and the titanium sheets in the experimental group were more conducive to the proliferation of MC3T3-E1 cells.Active oxygen fluorescence probe detection exhibited that compared with the other two groups,the fluorescence intensity of active oxygen on the surface of the experimental group was significantly reduced.The results of alkaline phosphatase and alizarin red S staining showed that the osteogenic differentiation and extracellular matrix mineralization of MC3T3-E1 cells on the surface of titanium sheets in the experimental group were stronger than those in the other two groups.(4)These results show that the polyphenol-mediated copper ion coating has strong antibacterial and antioxidant properties and promotes osteogenic differentiation.

Objective To investigate the effectiveness of the integrated schistosomiasis control programme in Sichuan Province during the stage moving from transmission interruption to elimination (2015—2023), so as to provide insights into formulation of the schistosomiasis control measures during the post-elimination stage. Methods Schistosomiasis control data were retrospectively collected from departments of health, agriculture and rural affairs, forestry and grassland, water resources, and natural resources in Sichuan Province from 2015 to 2023, and a database was created to document examinations and treatments of human and livestock schistosomiasis, and snail survey and control, conversion of paddy fields to dry fields, ditch hardening, rivers and lakes management and building of forests for snail control and schistosomiasis prevention. The completion of schistosomiasis control measures was investigated, and the effectiveness was evaluated. Results A total of 20 545 155 person-times received human schistosomiasis examinations in Sichuan Province during the period from 2015 to 2023, and 232 157 person-times were seropositive, with a reduction in the seroprevalence from 2.10% (44 299/2 107 003) in 2015 to 1.12% (9 361/837 896) in 2023 (χ2 = 7.68, P < 0.001). The seroprevalence of human schistosomiasis appeared a tendency towards a decline in Sichuan Province over years from 2015 to 2023 (b = −8.375, t = −10.052, P < 0.001); however, no egg positive individuals were identified during the period from 2018 to 2023, with the prevalence of human Schistosoma japonicum infections maintained at 0. Expanded chemotherapy was administered to 2 754 515 person-times, and medical assistance of advanced schistosomiasis was given to 6 436 persontimes, with the treatment coverage increasing from 46.80% (827/1 767) in 2015 to 64.87% (868/1 338) in 2023. Parasitological tests for livestock schistosomiasis were performed in 35 113 herd-times, and expanded chemotherapy was administered to 513 043 herd-times, while the number of fenced livestock decreased from 121 631 in 2015 to 103 489 in 2023, with a reduction of 14.92%. Snail survey covered 433 621.80 hm2 in Sichuan Province from 2015 to 2023, with 204 602.81 hm2 treated by chemical control and 4 637.74 hm2 by environmental modifications. The area of snail habitats decreased from the peak of 5 029.80 hm2 in 2016 to 3 709.72 hm2 in 2023, and the actual area of snail habitats decreased from the peak of 8 585.48 hm2 in 2016 to 473.09 hm2 in 2023. The mean density of living snails remained low across the study period except in 2017 (0.62 snails/0.1 m2). Schistosomiasis control efforts by departments of agriculture and rural affairs in Sichuan Province included conversion of paddy fields to dry fields covering 153 346.93 hm2, hardening of 6 110.31 km ditches, building of 70 356 biogas digesters, replacement of cattle with 227 161 sets of machines, and captive breeding of 21 161 070 livestock from 2015 to 2023, and the control efforts by departments of water resources included rivers and lakes management measuring 5 676.92 km and renovation of 2 331 irrigation areas, while the control efforts by departments of forestry and grassland included building of forests for snail control and schistosomiasis prevention covering 23 913.33 hm2, renovation of snail control forests covering 8 720 hm2 and newly building of shelterbelts covering 764 686.67 hm2. All 63 endemic counties (cities and districts) had achieved the criterion for schistosomiasis elimination criteria in Sichuan Province by the end of 2023. Conclusion Following the integrated control efforts from 2015 to 2023, remarkable achievements have been obtained in the schistosomiasis control programme in Sichuan Province, with all endemic counties successfully attaining the schistosomiasis elimination target at the county level.

BackgroundNon-suicidal self-injury (NSSI) behavior among adolescents has become a global public health concern. Anxiety and depression are considered key factors influencing NSSI behavior, while social support may play a protective role in alleviating emotional and behavioral issues. However, existing research has primarily focused on the direct impact of individual factors on NSSI behavior, with insufficient exploration of the combined effects of anxiety, depression and social support. ObjectiveTo investigate the direct effect of anxiety on NSSI, the mediating role of depression and the moderating role of social support in relationship between anxiety and NSSI behavior, thus to provide references for the prevention and intervention of NSSI behavior among adolescents. MethodsIn February 2022, a total of 40 820 students in grades 7 to 12 across 10 middle schools in a district of Chengdu were selected as participants, and they were assessed using Generalized Anxiety Disorder Scale-7 item (GAD-7), Patient's Health Questionnaire Depression Scale-9 item (PHQ-9), Social Support Scale for Urban Students (SSSUS) and Adolescent Self-Harm Scale (ASHS). Pearson correlation analysis was conducted to examine the correlations between scale scores among adolescents with NSSI behaviors. Mediation and moderation analyses were performed using Process 3.5 in SPSS, and the significance was tested with bootstrapping. The interaction was visualized by using simple slope analysis. ResultsAmong 34 534 (84.60%) valid respondents, 542 adolescents (1.57%) reported engaging in NSSI behavior. Significant differences in gender, GAD-7 scores, PHQ-9 scores, and SSSUS scores were observed between NSSI behavior group and non-NSSI group (χ²/t=62.889, 71.120, 94.365, -41.464, P<0.01).Adolesents with NSSI showed positive correlations between GAD-7 scores and both ASHS and PHQ-9 scores (r=0.158, 0.166, P<0.01). PHQ-9 scores were positively correlated with ASHS scores (r=0.364, P<0.01), but negatively correlated with SSSUS scores (r=-0.290, P<0.01). SSSUS scores were negatively correlated with ASHS scores (r=-0.247, P<0.01). Depression partially mediated the relationship between anxiety and NSSI behavior, with an effect size of 0.544 (95% CI: 0.162~0.944), accounting for 35.79% of the total effect. Social support moderated the relationship between depression and NSSI bahavior, with an effect value of -0.082 (95% CI: -0.135~-0.029). ConclusionAnxiety not only directly influences NSSI bahavior among adolescents, also indirectly exacerbates it through depression, while social support mitigates the impact of depression on NSSI behavior.

PURPOSE:
The rate of complications among patients undergoing surgery has increased due to infection with SARS-CoV-2 and other variants of concern. However, Omicron has shown decreased pathogenicity, raising questions about the risk of postoperative complications among patients who are infected with this variant. This study aimed to investigate complications and related factors among patients with recent Omicron infection prior to undergoing orthopedic surgery.
METHODS:
A historical control study was conducted. Data were collected from all patients who underwent surgery during 2 distinct periods: (1) between Dec 12, 2022 and Jan 31, 2023 (COVID-19 positive group), (2) between Dec 12, 2021 and Jan 31, 2022 (COVID-19 negative control group). The patients were at least 18 years old. Patients who received conservative treatment after admission or had high-risk diseases or special circumstances (use of anticoagulants before surgery) were excluded from the study. The study outcomes were the total complication rate and related factors. Binary logistic regression analysis was used to identify related factors, and odds ratio (OR) and 95% confidence interval (CI) were calculated to assess the impact of COVID-19 infection on complications.
RESULTS:
In the analysis, a total of 847 patients who underwent surgery were included, with 275 of these patients testing positive for COVID-19 and 572 testing negative. The COVID-19-positive group had a significantly higher rate of total complications (11.27%) than the control group (4.90%, p < 0.001). After adjusting for relevant factors, the OR was 3.08 (95% CI: 1.45-6.53). Patients who were diagnosed with COVID-19 at 3-4 weeks (OR = 0.20 (95% CI: 0.06-0.59), p = 0.005), 5-6 weeks (OR = 0.16 (95% CI: 0.04-0.59), p = 0.010), or ≥7 weeks (OR = 0.26 (95% CI: 0.06-1.02), p = 0.069) prior to surgery had a lower risk of complications than those who were diagnosed at 0-2 weeks prior to surgery. Seven factors (age, indications for surgery, time of operation, time of COVID-19 diagnosis prior to surgery, C-reactive protein levels, alanine transaminase levels, and aspartate aminotransferase levels) were found to be associated with complications; thus, these factors were used to create a nomogram.
CONCLUSION
Omicron continues to be a significant factor in the incidence of postoperative complications among patients undergoing orthopedic surgery. By identifying the factors associated with these complications, we can determine the optimal surgical timing, provide more accurate prognostic information, and offer appropriate consultation for orthopedic surgery patients who have been infected with Omicron.

OBJECTIVE:
To evaluate the clinical efficacy and safety of Yangxue Qingnao Pills (YXQNP) combined with amlodipine in treating patients with grade 1 hypertension.
METHODS:
This is a multicenter, randomized, double-blind, and placebo-controlled study. Adult patients with grade 1 hypertension of blood deficiency and Gan (Liver)-yang hyperactivity syndrome were randomly divided into the treatment or the control groups at a 1:1 ratio. The treatment group received YXQNP and amlodipine besylate, while the control group received YXQNP's placebo and amlodipine besylate. The treatment duration lasted for 180 days. Outcomes assessed included changes in blood pressure, Chinese medicine (CM) syndrome scores, symptoms and target organ functions before and after treatment in both groups. Additionally, adverse events, such as nausea, vomiting, rash, itching, and diarrhea, were recorded in both groups.
RESULTS:
A total of 662 subjects were enrolled, of whom 608 (91.8%) completed the trial (306 in the treatment and 302 in the control groups). After 180 days of treatment, the standard deviations and coefficients of variation of systolic and diastolic blood pressure levels were lower in the treatment group compared with the control group. The improvement rates of dizziness, headache, insomnia, and waist soreness were significantly higher in the treatment group compared with the control group (P<0.05). After 30 days of treatment, the overall therapeutic effects on CM clinical syndromes were significantly increased in the treatment group as compared with the control group (P<0.05). After 180 days of treatment, brachial-ankle pulse wave velocity, ankle brachial index and albumin-to-creatinine ratio were improved in both groups, with no statistically significant differences (P>0.05). No serious treatment-related adverse events occurred during the study period.
CONCLUSIONS
Combination therapy of YXQNP with amlodipine significantly improved symptoms such as dizziness and headache, reduced blood pressure variability, and showed a trend toward lowering urinary microalbumin in hypertensive patients. These findings suggest that this regimen has good clinical efficacy and safety. (Registration No. ChiCTR1900022470).

BackgroundThe distressingly high prevalence of depressive symptoms among adolescents exerts profound impacts on their physical and psychological development, urgently necessitating effective preventive interventions. Existing studies, however, have predominantly focused on isolated risk factors, neglecting to construct an integrated model that systematically disentangles the intricate relationships linking parenting styles, learning burnout, and childhood trauma to adolescent depressive symptoms. Moreover, the potential protective roles of social support and psychological resilience in this context remain insufficiently elucidated. ObjectiveTo construct a structural equation model encompassing multiple pathways to unravel the comprehensive mechanisms through which negative parenting styles, childhood trauma, learning burnout, psychological resilience, and social support collectively influence adolescent depressive symptoms, thereby providing evidence-based intervention strategies. MethodsA stratified sampling technique was utilized to recruit 5 865 students from 12 middle schools in Chengdu City, Sichuan Province from March to May 2022. Participants were assessed using the following validated instruments: the Short-form Egna Minnen av Barndoms Uppfostran (s-EMBU), the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Adolescent Student Burnout Inventory, the Patients' Health Questionnaire Depression Scale-9 item (PHQ-9), the Social Support Rating Scale (SSRS),and the Connor-Davidson Resilience Scale (CD-RISC). A partial least squares structural equation modeling (PLS-SEM) approach was employed to construct a predictive framework examining the complex network of pathways through which negative parenting styles, childhood trauma, learning burnout, psychological resilience,and social support collectively influence depressive symptoms in adolescents. ResultsThe PHQ-9 scores demonstrated significant positive correlations with the scores on s-EMBU overprotection subscale (r=0.272, P<0.01), s-EMBU rejection subscale (r=0.368, P<0.01), CTQ-SF (r=0.288, P<0.01) and Adolescent Student Burnout Inventory (r=0.587, P<0.01). Conversely, significant negative correlations were observed between PHQ-9 scores and both SSRS (r=-0.532, P<0.01) and CD-RISC scores (r=-0.418, P<0.01). Negative parenting styles (β=0.113, 95% CI: 0.087-0.138) and learning burnout (β=0.339, 95% CI: 0.315-0.364) emerged as significant positive predictors of depressive symptoms, with childhood trauma mediating the relationship between negative parenting styles and depressive symptoms (effect size=0.018, 95% CI: 0.013-0.024). Social support servesed as a mediating pathway between negative parenting styles and depressive symptoms (β=0.080, 95% CI: 0.069-0.092), as well as between negative parenting styles and childhood trauma (β=0.041, 95% CI: 0.032-0.050). It also functioned as an intermediary pathway linking learning burnout to depressive symptoms (β=0.092, 95% CI: 0.081-0.104) and connecting learning burnout with childhood trauma (β=0.048, 95% CI: 0.037-0.058). Additionally, psychological resilience serveed as a mediating pathway between negative parenting styles and depressive symptoms (β=0.004, 95% CI: 0.002-0.007), between learning burnout and depressive symptoms (β=0.037, 95% CI: 0.023-0.052), and between childhood trauma and depressive symptoms (β=0.003, 95% CI: 0.001-0.006). ConclusionLearning burnout exerts a direct effect on adolescent depressive symptoms. Negative parenting styles influence depressive symptoms both directly and indirectly through childhood trauma. Furthermore, social support and psychological resilience serve as mediator linking negative parenting styles and learning burnout to depressive symptoms in adolescents.
