OBJECTIVE:To summarize the current status,hotspots,emerging trends,and frontiers of global research on the treatment of adolescent idiopathic scoliosis to provide reference and guidance for future related research. METHODS:The literature related to the treatment of adolescent idiopathic scoliosis was retrieved on the Web of Science Core Collection(WOSCC)database from 2013 to 2023.CiteSpace 6.2.R1 software was used for visual analysis of countries,institutions,authors,and keywords. RESULTS AND CONCLUSION:(1)A total of 561 English articles were included in this study.Among countries,institutions,and authors,the United States has contributed the most.Nanjing University and Qiu,Yong(Affiliated Drum Tower Hospital,Nanjing University School of Medicine)are the most published institution and author.The academic journal with the largest number of articles is the European Spine Journal.(2)In the analysis of cited literature,the top 10 most cited articles mainly describe the effects of surgical treatment and conservative treatment on improving adolescent idiopathic scoliosis,especially improving the curvature of patients.(3)Through the summary of highly cited articles and the keyword clustering,keyword prominence in-depth mining,the research hotspots are currently the relationship between Cobb angle and treatment choice,the therapeutic effect of exercise therapy and the therapeutic effect of posterior vertebral fusion.(4)The prognosis of patients with different curvatures has not been studied in depth,and the etiology of adolescent idiopathic scoliosis has not been clarified,so the relationship between curvature and prognosis and the etiology of adolescent idiopathic scoliosis may be a new research trend in the future.

Objective:To investigate the efficacy of tibiofibular-based reconstruction technique with single femoral tunnel for Fanelli type C posterolateral complex (PLC) injury.Methods:A retrospective case series study was conducted to analyze the clinical data of 16 patients with Fanelli type C PLC injury admitted to Tianjin Hospital from July 2016 to July 2019, including 10 males and 6 females, aged 20-61 years [(36.5±13.9)years]. PLC reconstruction was performed by tibiofibular-based technique with single femoral tunnel using gracilis tendon and semi-tendinosus autografts. If the posterior and anterior cruciate ligaments (PCL/ACL) rupture were combined, arthroscopic single bundle reconstruction was performed simultaneously. If the posteromedial corner (PMC) injury was combined, PMC repair or reconstruction surgery was performed simultaneously. Operation time and intraoperative blood loss were recorded. When the bone needle and tunnel for PLC were drilled during the operation, the interference of the femoral tunnel through the cruciate ligament was observed under the arthroscope. Before and at 6 and 12 months after operation, the varus stability of the knee joint was evaluated with the difference of lateral joint space width of both knees and the International Knee Documentation Committee (IKDC) objective classification of varus stability of the knee joint; the external rotation stability was evaluated with the difference of external rotation angle of both knees and the IKDC objective classification of external rotation stability of the knee joint. Before, at 6 and 12 months after operation and at the last follow-up, IKDC 2000 subjective score and Lysholm score were compared. The occurrence of complications was observed.Results:All the patients were followed up for 12-36 months [24(15, 33)months]. The operation time was 100-220 minutes [175.0(111.3, 200.0)minutes], with intraoperative blood loss of 30-150 ml [(84.3±36.5)ml]. Intraoperative arthroscopy showed no interference of perforation between PLC and cruciate ligament femoral tunnel. The differences of lateral joint space width of both knees at 6 and 12 months after operation were 0.5(0.2, 1.4)mm and 0.6(0.2, 1.5)mm respectively, which were both significantly improved compared with 12.1(10.8, 12.6)mm before operation ( P<0.05), while there was no significant difference at 6 and 12 months after operation ( P>0.05). The IKDC objective classification of varus stability of the knee joint was grade A in 13 patients, grade B in two and grade C in one at 6 or 12 months after operation, and showed statistical difference from grade D in all the patients before operation ( P<0.01). At 6 and 12 months after operation, the difference of external rotation angle of both knees was -2.0(-3.2, 1.3)° and -1.4(-3.0, 1.7)° respectively, which were significantly improved compared with 16.8(13.9, 18.4)° before operation ( P<0.05), while there was no significant difference at 6 and 12 months after operation ( P>0.05). IKDC objective classification of external rotation stability of the knee joint was grade A in 14 patients, grade B in one and grade C in one at 6 or 12 months after operation, and showed statistical difference from grade C in 14 patients and grade D in 2 before operation ( P<0.01). At 6 and 12 months after operation and at the last follow-up, the IKDC 2000 subjective scores [(76.3±4.7)points, (80.3±4.4)points, (79.9±3.8)points respectively] and the Lysholm scores [(76.1±3.9)points, (81.1±4.3)points, (82.8±3.2)points respectively] were significantly improved compared with those before operation [(48.6±3.7)points and (52.6±2.4)points] ( P<0.05). The IKDC 2000 subjective scores and Lysholm scores were significantly improved at 12 months after operation and at the last follow-up than those at 6 months after operation ( P<0.05). There were no significant differences in the IKDC 2000 subjective scores and Lysholm scores at 12 months after operation and at the last follow-up ( P>0.05). There were no complications such as wound infection, vascular and nerve injury, joint stiffness or ectopic ossification. Conclusion:For Fanelli type C PLC injury, tibiofibular-based reconstruction technique with single femoral tunnel reduces the interference between the lateral femoral tunnels, significantly improves the varus and external rotation stability and the function of the knee joint, and has few complications and satisfactory short-term clinical efficacy.

Objective:To investigate the mechanism of curcumin affecting HIV-1 infection co-receptor CCR5 by regulating transcription factor FOXP3.Methods:Binding sites of transcription factor FOXP3 on CCR5 promoter were predicted and analyzed by bioinformatics method.AutoDock 4.2 software was used to connect curcumin and FOXP3 flexibly.MTT assay was used to detect cyto-toxcity of curcumin on activity of Jurkat cells.qRT-PCR and Western blot were used to detect expression levels of CCR5 and FOXP3 mRNA and protein in Jurkat cells that were treated with different concentrations of curcumin.pcDNA3.1-FOXP3 expression vector was built and combined with the prediction results of transcription factors.The mutant CCR5 gene fragment was amplified by Overlap PCR,and the mutant CCR5 promoter recombinant vector pFireRluc-Mt-CCR5 was constructed.Binding site between transcription fac-tor FOXP3 and CCR5 promoter was verified by double luciferase reporter gene assay.Results:Results of JASPAR transcription factor prediction showed that there was a binding site between CCR5 promoter and transcription factor FOXP3;molecular docking results showed that curcumin could bind to the active region of FOXP3;MTT results showed that curcumin inhibited the activity of Jurkat cells after 24 hours,and the IC50 was 34.48 μmol/L.qRT-PCR and Western blot showed that expression levels of CCR5 and FOXP3 mRNA and protein were decreased in a dose-dependent manner after different concentrations of curcumin treated Jurkat cells;double luciferase reporter gene confirmed that FOXP3 could bind to CCR5 promoter,and the transcription factor FOXP3 could regulate the activity of CCR5 promoter;results of the recovery experiment of FOXP3 on curcumin showed that when the curcumin concentration was 60 μmol/L,relative value of luciferase activity in HEK293T cells with pcDNA3.1-FOXP3 and pFireRluc-Wt-CCR5 was signifi-cantly higher than that in pFireRluc-Wt-CCR5+curcumin-60 group(P<0.01).Conclusion:FOXP3 can regulate the activity of CCR5 promoter,and the mechanism may be that curcumin affects activity of CCR5 promoter by acting on binding site of FOXP3 and CCR5 promoter.

In the past few years, there has seen an increase in the detection rate of early upper gastric cancer. Early upper gastric cancer is of good prognosis. How to further enhance the postoperative quality of life of patients has increasingly become an issue of concern. This has naturally given rise to function-preserving proximal gastrectomy. However, due to its damage to the original structure of cardia and its vicinity, proximal gastrectomy is prone to postoperative reflux. To prevent postoperative reflux, various ways of digestive tract reconstruction have emerged one after another, but the optimal way thereof remains controversial. Therefore, reducing postoperative reflux through an appropriate way of digestive tract reconstruction has been taken as a focus of proximal gastrectomy. Esophagogastric anastomosis with seromuscular flap technique, as a way of digestive tract reconstruction, builds an "artificial cardia" on the basis of guarantee of normal entry of food into the digestive tract, and functions against postoperative reflux. For its good anti-reflux effect, eso-phagogastric anastomosis with seromuscular flap technique has gradually become a research focus. On top of the latest research progress at home and abroad and relevant evidence-based medicine, the authors provide on the principles, key points, improvement, postoperative status, and applica-tion of esophagogastric anastomosis with seromuscular flap technique in laparoscopic proximal gastrectomy.

Isochrysis galbana is considered an ideal bait for functional foods and nutraceuticals of humans because of its high fucoxanthin(Fx)content.However,multi-omics analysis of the regula-tory networks for Fx biosynthesis in I.galbana has not been reported.In this study,we report a high-quality genome assembly of I.galbana LG007,which has a genome size of 92.73 Mb,with a contig N50 of 6.99 Mb and 14,900 protein-coding genes.Phylogenetic analysis confirmed the monophyly of Haptophyta,with I.galbana sister to Emiliania huxleyi and Chrysochromulina tobinii.Evolutionary analysis revealed an estimated divergence time between I.galbana and E.huxleyi of～133 million years ago.Gene family analysis indicated that lipid metabolism-related genes exhibited significant expansion,including IgPLMT,IgOAR1,and IgDEGS1.Metabolome analysis showed that the content of carotenoids in I.galbana cultured under green light for 7 days was higher than that under white light,and β-carotene was the main carotenoid,accounting for 79.09％of the total carotenoids.Comprehensive multi-omics analysis revealed that the content of β-carotene,antheraxanthin,zeaxanthin,and Fx was increased by green light induction,which was significantly correlated with the expression of IgMYB98,IgZDS,IgPDS,IgLHCX2,IgZEP,IgLCYb,and IgNSY.These findings contribute to the understanding of Fx biosynthesis and its regulation,pro-viding a valuable reference for food and pharmaceutical applications.

Objective: To establish a method for simultaneous and rapid detecting of the polymorphisms in Cytochrome P450 2C9 (CYP2C9), CYP2C19, CYP4F2, Vitamin K epoxide reductase (VKORC1) and ATP-binding cassette subfamily B member1 (ABCB1) gene, which were associated with warfarin and clopidogrel, based on liquid phase chip technology. Methods: Method establishment. The eight gene sequences near targeted sites related to warfarin and clopidogrel were found in Genbank, and the specific primers and probes were designed. Through multiple PCR amplification, followed by allele specific primer extension (ASPE), and MagPlex-Tag microspheres hybridization, the suspension array Luminex 200 system step-by-step, the genotypes were determined by fluorescence signal. The reaction system was optimized and its methodological evaluation was performed. 260 patients with antithrombotic therapy from Dongguan houjie hospital were recruited in this study form June 2017 to December 2018. The eight genotypes of the 260 patients were detected by the established method, and the results were compared with the sequencing results. Results: The results of 260 samples showed that allelic median fluorescence intensity (MFI) ratios of homozygotes (mutant/wild-type) were all greater than 0.9 or less than 0.1, and all the allelic MFI ratios of heterozygotes were between 0.3 and 0.6. The within run and between run coefficients of variance for allelic MFI ratios were lower than 6.4% and 10.9%, respectively. The minimum DNA template requirements was 0.75ng. The genotypes of 260 patients determined by the established method were completely concordant with the sequencing results. Conclusion A method was established successfully for rapid detecting the genotypes which associated with warfarin and clopidogrel based on liquid phase chip technology.

Objective To investigate dynamic changes of serum Tau proteins and their correlation with cognitive dysfunction in patients with acute traumatic brain injury (TBI).Methods A total of 95 patients with acute TBI were retrospectively studied by case-control study.There were 61 males and 34 females,with age of 16-65 years [(40.7 ± 13.6)years].The Glasgow coma scale (GCS) was 3-8 points in 9 patients,9-12 points in 11,and 13-15 points in 75.A total of 30 healthy physical examinees were recruited as control group.The levels of Tau proteins were measured at days 1,3,5,7 and 14 after TBI.The cognitive dysfunction was evaluated by the Montreal Cognitive Assessment (MoCA) score at 6 months after injury.The correlation between Tau protein levels at different time points and MoCA was determined.Results The serum Tau proteins of TBI group was significantly higher than that of control group at all time points (P ＜ 0.05).In TBI group,39 (41％) out of 95 patients developed cognitive dysfunction assessed by MoCA scale.The main manifestations of cognitive dysfunction were the defects in visual spatial and acting function,delayed memory,language,abstract,attention and calculation,with statistical significance compared with control group (allP ＜ 0.05).The serum Tau proteins of patients with cognitive dysfunction were significantly higher than those without cognitive dysfunction at all time points after TBI (P ＜ 0.05).Tau proteins at days 1,3,5 after TBI was significantly correlated with cognitive dysfunction at 6 months after TBI (P ＜ 0.05).Conclusions The levels of serum Tau proteins show a significant increase after TBI,the early changes of which are statistically related to cognitive dysfunction.The early changes of serum Tau protein after TBI can be used as a reliable biomarker for early prediction of cognitive function prognosis.

Objective The key points in the epithelial-mesenchymal transition ( EMT) procedure include the downregula-tion of epithelial protein (E cadherin) and the upregulation of cell activity and cell matrix generation .The aim of this study was to es-tablish a method for primary culture and identification of mouse renal tubular epithelial cells and to explore whether the activation of C3aR can induce epithelial-to-mesenchymal transition in mouse primary renal epithelial cells .
