Objective: To explore the effectiveness of different intervention modalities on nonsuicidal selfinjury (NSSI) in adolescents, so as to provide an evidencebased basis for the intervention strategy of NSSI in adolescents. Methods: Randomized controlled trials on interventions for adolescent NSSI were retrieved from databases, such as CNKI, Wanfang, VIP, CBM, Web of Science, PubMed, Embase, and Cochrane Library, spanning from the inception of these databases to March 5, 2025. Network Metaanalysis was performed by using Stata 17.0 and Review Manager 5.3 software, and the standardized mean difference (SMD) and 95%CI were used as the effect indicators to compare the differences in the effectiveness of the interventions and rank the effect. Results: A total of 26 articles with 2 034 adolescents with NSSI were included in the study, including 10 intervention modalities:dialectical behavior therapy, emotional regulation intervention, mentalizationbased therapy, family therapy, cutting down programme, cognitive behavioral therapy, narrative therapy, stepped care approach, positive psychological intervention, and acceptance and commitment therapy. The results showed that compared with the treatment as usual, positive psychological intervention [SMD(95%CI)=-2.12(-3.51 to -0.74)], stepped care intervention [SMD(95%CI)=-2.07(-3.43 to -0.71)], and dialectical behavior therapy [SMD(95%CI)=-1.70(-2.60 to -0.80)], cognitive behavioral therapy [SMD(95%CI)=-1.54(-2.61 to -0.48)], and acceptance and commitment therapy[SMD(95%CI)=-1.50(-2.68 to -0.32)] were statistically significant differences in reducing adolescents NSSI behaviors(P<0.05). Positive psychological intervention, stepped care intervention, and dialectical behavior therapy were more effective than the mentalizationbased therapy and the cutting down programme (SMD=-2.08, -2.03, -1.66, -2.06, -2.01, -1.64,P<0.05); the area under the cumulative ranking probability graph revealed that positive psychological intervention may have the best effect in improving NSSI among adolescents (82.5). Conclusions Positive psychological interventions show the best results in improving adolescent NSSI among multiple intervention modalities. It is recommended to give priority to positive psychological interventions in clinical interventions.

Neural loops are formed by interconnections between neurons through synaptic structures,which are the basic units of information transmission and processing in the brain and play an important role in the regulation of neural functions.After stroke,neural connections between the infarct and peri-infarct regions and the remote area are damaged,resulting in patients being at risk of neurological dysfunction or even disability.However,with advances in detection technology,an increasing number of studies are demonstrating that patients with stroke can undergo some functional recovery during the chronic phase,possibly via a mechanism related to the re-establishment of synaptic connections and neural circuits.Therefore,the development of specific technology to identify and manipulate neuronal activity patterns,as well as the use of high-resolution temporal and spatial imaging strategies to decipher these neurological processes,will allow us to understand the whole-brain network dynamics of stroke recovery and the mechanisms by which neural loop reestablishment occurs.Furthermore,we may be able to neurobiologically comprehend the closed-loop mechanisms that underlie the development of stroke pathology and their relationship to behavioral outcomes.Current technologies used for studying neural circuits include optogenetics,chemical genetics,in vivo calcium imaging,and functional magnetic resonance imaging.This article introduces the working principles of these four major technologies and focuses on summarizing the result of their respective application in resolving neural remodeling after stroke.We briefly analyze the application scenarios,advantages and disadvantages,and future development trends of each technique.This paper will help clinical and basic researchers to use these technologies to discover new therapeutic strategies and evaluate the effectiveness of rehabilitation strategies.

Cardiovascular disease is a health hazard to humans and systolic heart failure due to myocardial infarction is a major cause of death.It was previously thought that myocardial cells of the adult mammalian heart possess a limited ability to proliferate and self-renew.However,it has been widely reported that mammals have the ability to regenerate the myocardium,which is restricted to early postnatal life,and that it is strong enough to repair damaged heart tissue.The discovery of myocardial regeneration in neonatal hearts has provided an ideal animal model to investigate the mechanisms that affect myocardial regeneration,and many mechanisms that reverse myocardial cell cycle arrest and promote myocardial regeneration have been revealed.In this article,we review the factors affecting gene expression for myocardial regeneration(e.g.,ncRNAs and transcription factors),myocardial regeneration-related signaling pathways,and the regulation of myocardial regeneration by non-myocardial cells(e.g.,extracellular matrix,immune response,and epicardium)to provide directions for achieving myocardial regeneration after myocardial injury in adult mammals.

While biological identification technology has brought positive impacts to society,it has also raised ethical issues,such as privacy protection and fair application.Taking the technical dimension as the main line is the foundation of efficient and agile governance of ethical issues in biological identification technology.Based on the technology track theory,a framework for ethical governance of biological identification technology was constructed,and the track and ethical governance technology of biological identification technology were sorted out.The key to efficient governance lies in the application of ethical governance technologies such as privacy and security protection and fairness detection at the three levels of the entire lifecycle of biological identification technology,including data,algorithms,and systems.Taking Hikvision's facial recognition technology as an example,this paper elaborated that increasing the application of ethical governance technology is of great significance to ensure the trustworthy and sustainable development of biological identification technology.

Objective:To evaluate the cerebral infarct volume and the nerve fiber connectivity between cortical and neurogenesis-related regions in the mouse model of reperfusion after middle cerebral artery occlusion (MCAO) by 11.7 Tesla(11.7 T) magnetic resonance imaging (MRI).Methods:MCAO models were established in SPF grade adult male C57BL/6 mice using the suture-occluded method.MRI scans were performed at 3 days before and 1 day after modeling.Infarct volumes were calculated, and nerve fiber tracking was performed on specific brain regions to analyze the nerve fiber number and the parameters of fractional anisotropy(FA), mean diffusivity(MD), axial diffusivity (AD)and radial diffusivity(RD). SPSS 26.0 was used for statistical analysis, and paired t test was used to compare the data before and after modeling. Results:(1) After MCAO-induced ischemia, the infarct volume was up to (35.11±17.57)mm 3, and the FA value of the infarct area was significantly reduced compared with that of before modeling( t=4.73, P<0.01). (2) At the anterior-posterior(AP): + 1.2 mm section, the results of fiber tracking showed that compared with before modeling, the number of fiber bundles originating from the dorsal horn of the lateral sub-ventricle zone(SVZ)to the cortex reduced ((92 584.20±14 751.00) vs (59 815.60±6 752.46), t=4.87, P<0.01), and the number of fiber bundles projected to the infarcted area reduced ((107 671.40±10 497.57) vs (61 658.60±10 178.21), t=6.43, P<0.01). FA, AD, MD, and RD values were all decreased in different degrees( t=3.38-6.43, all P<0.05). (3) At the AP: -3.8 mm section, the number of fiber bundles originating from the dorsal horn of the SVZ to the cortex decreased (after modeling(96 944.00±18 331.09), before modeling(58 767.80±16 445.25), t=2.99, P<0.05), and the values of FA, AD, MD and RD decreased after ischemia ( t=7.30, 5.05, 6.74, 4.13, all P<0.05). Conclusion:The ultra-high field strength of 11.7 T MRI can accurately detect the following results that the number of nerve fiber bundles from the SVZ to the cortex or infarct area are both significantly reduced, and diffusion tensor parameters are consistently changed in mice after 1 day of ischemia-reperfusion.

ObjectiveTo observe the effect of the Fangfeng Tongshengsan on post-chemoembolization syndrome with primary liver cancer or postoperative liver metastases of colorectal cancer. MethodSeventy-two patients suffered from post-chemoembolization syndrome after transcatheter hepatic arterial chemoembolization were randomly divided into 2 groups， including a Fangfeng Tongshengsan group and a control group， with 36 patients in each group. The patients in Fangfeng Tongshengsan group orally took the decoction for consecutive 7 d. The patients in the control group were physically cooled down with alcohol rub bath and ice pack for consecutive 7 d. Furthermore， the difference of fever， Karnofsky performance status （KPS）， pain in the liver region， nausea vomiting， constipation， and liver function between these two groups were observed. ResultCompared with the control group， Fangfeng Tongshengsan significantly relieved fever， reduced the body temperature （P<0.05）， and shortened the duration of fever （P<0.05）， indicating that Fangfeng Tongshengsan remarkably improved the KPS （P<0.05）. Meanwhile， Fangfeng Tongshengsan obviously alleviated nausea， vomiting， and constipation status and shortened the duration time compared with the control group （P<0.05）. In addition， the parameters of liver function including alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， γ-glutamyl transpeptidase （GGT）， and total bilirubin （TBIL） were significantly decreased in the Fangfeng Tongshengsan group （P<0.05）， which indicated that Fangfeng Tongshengsan alleviated liver dysfunction of patients with post-chemoembolization syndrome. ConclusionFangfeng Tongshengsan can be used to treat post-chemoembolization syndrome with primary liver cancer and postoperative liver metastases of colorectal cancer.

Rheumatoid arthritis is a chronic, systemic autoimmune disease predominantly based on joint lesions with an extremely high disability and deformity rate. Several drugs have been used for the treatment of rheumatoid arthritis, but their use is limited by suboptimal bioavailability, serious adverse effects, and nonnegligible first-pass effects. In contrast, transdermal drug delivery systems (TDDSs) can avoid these drawbacks and improve patient compliance, making them a promising option for the treatment of rheumatoid arthritis (RA). Of course, TDDSs also face unique challenges, as the physiological barrier of the skin makes drug delivery somewhat limited. To overcome this barrier and maximize drug delivery efficiency, TDDSs have evolved in terms of the principle of transdermal facilitation and transdermal facilitation technology, and different generations of TDDSs have been derived, which have significantly improved transdermal efficiency and even achieved individualized controlled drug delivery. In this review, we summarize the different generations of transdermal drug delivery systems, the corresponding transdermal strategies, and their applications in the treatment of RA.

Objective:To investigate the role of recombinant phospholipase A2 receptor (PLA2R) tandem dominant epitopes (PLA2RTD) in the removal of anti-PLA2R autoantibodies (anti-PLA2R) from primary membranous nephropathy (PMN).Methods:The recombinant protein PLA2RTD (cysteine-rich domain, C-type lectin like domain 1 and C-type lectin like domain 7) was expressed in bacmid-insect cell expression system. Circular dichroism was used to determine the secondary structure of PLA2RTD. Enzyme-linked immunosorbent assay and immunofluorescence were used to determine the biological activity of PLA2RTD. Epoxy activation method was used to couple the recombinant PLA2RTD and agarose gel CL-6B microspheres for preparing specific immune adsorbent of anti-PLA2R.Results:The study achieved the expression of PLA2RTD in the first time from the bacmid-insect cell system, demonstrating the good immunogenicity and high binding specificity of PLA2RTD. A single in vitro adsorption of PLA2RTD could averagely eliminate 76.66% of anti-PLA2R [(6.66±0.30) RU/ml vs. (28.54±2.10) RU/ml], the changes of IgG, IgA, albumin, β2 microglobulin, interleukin 6, and tumor necrosis factor α were all less than 4% after completion of adsorption, and the second or third repeated use of PLA2RTD could maintain the adsorption efficiency of about 65%. Conclusion:PLA2RTD-based specific immunosorbent can effectively remove anti-PLA2R in plasma, which provides a new way to specifically remove PMN-related autoantibodies.

Objective:To investigate the application value of pelvic floor ultrasound in screening early postpartum stress urinary incontinence (SUI).Methods:A total of 220 postpartum women, who were admitted by the Department of Gynecology and Obstetrics of The People's Hospital of Hechi from January 2018 to June 2019, were selected for this study. These women were divided into SUI ( n = 52) and no SUI ( n = 168) groups according to whether SUI occurred within 42 days after delivery. Pelvic floor ultrasound parameters and clinical data were compared between the two groups. The effects of each ultrasound parameter on postpartum SUI were assessed. The receiver operating characteristic (ROC) curve was plotted for each parameter. The area under the ROC was calculated. The risk factors for postpartum SUI were investigated using the logistic regression analysis. Results:The number of deliveries (≥ 2 times), the proportion of women subjected to vaginal delivery, and neonatal weight in the SUI group were significantly higher than those in the no SUI group [ χ2 = 4.13, 3.30, t = 4.43, all P < 0.05]. There were significant differences in the bladder neck position and levator hiatus area in the resting state between the two groups ( t = 2.29, 3.09, both P < 0.05). There were significant differences in the bladder neck position, levator hiatus area, urethral rotation angle, and bladder neck mobility during the Valsalva movement between the two groups ( t = 13.14, 4.27, 15.64, 8.54, all P < 0.05). The areas under the ROC of bladder neck position and levator hiatus area in the resting state and the areas under the ROC of bladder neck position, levator hiatus area, urethral rotation angle, and bladder neck mobility during the Valsalva movement were 0.707, 0.725, 0.730, 0.771, 0.813, and 0.836, respectively. The area under the ROC of parameters used in combination was 0.849. Logistic regression analysis results revealed that the number of deliveries (≥ 2 times), bladder neck position (> 27.286 mm) and levator ani hiatus area in resting state (> 16.663 cm 2), and bladder neck position (< -2.774 mm), levator hiatus area (> 21.915 cm 2), urethral rotation angle (> 80.445°), and bladder neck mobility (> 30.501°) during the Valsalva movement were the risk factors for postpartum SUI. Conclusion:Combined use of pelvic floor ultrasound parameters is valuable for the diagnosis of postpartum SUI. Abnormal changes in the bladder neck position, levator ani hiatus area, urethral rotation angle, and bladder neck mobility are closely related to the occurrence of postpartum SUI. Therefore, combined use of pelvic floor ultrasound parameters can be preferred to screen early postpartum SUI.

Objective:To investigate the influence of hemoglobin glycation index (HGI) on the risk of incident chronic kidney disease (CDK) among nondiabetic patients.Methods:Prospective cohort study. At baseline, a total of 7 407 nondiabetic patients without a history of CKD from Pingguoyuan Community of the Shijingshan District in Beijing were included from December 2011 to August 2012, who were then divided into three groups according to the tertiles of their baseline HGI levels. The CKD incidence rate was compared among the different HGI groups at last follow-up. Cox multivariable regression was applied to evaluate whether HGI measures predicted CKD risk. Test for trend across tertiles were examined using ordinal values in separate models.Results:The mean age of the subjects was (56.4±7.5) years, and 4 933 (66.6%) were female. At mean follow-up of 3.23 years, 107 (1.4%) individuals developed CKD. The incidence of CKD was gradually increasing from the low to high HGI groups [1.1% (28/2 473) vs. 1.2% (31/2 564) vs. 2.0% (48/2 370), P=0.016]. In the multivariate Cox regression analysis, after adjustment for potential confounders, the high HGI group had a 68.5% increased risk of CKD compared with the low HGI group ( HR=1.685, 95% CI 1.023 to 2.774). CKD risk increased with increasing HGI tertiles ( P for trend=0.028). Conclusion:High HGI is associated with an increased risk for CKD in the nondiabetic population, indicating that HGI may help identify individuals at high risk for CKD.
