This study retrospectively analyzed the literature on the prevention and management of complications associated with hyaluronic acid injectable fillers.Starting with the physicochemical prop-erties and pharmacological research of hyaluronic acid,this review summarized its clinical application in facial injection,complications,and corresponding treatment modalities.Clinicians administering hy-aluronic acid injections should attach great importance to potential risks,adopt targeted preventive measures,and promptly address issues to maximize the avoidance of severe complications.

To summarize the clinical experience of Professor LIU Jinmin in treatment for epilepsy. It is believed that main pathogenesis of epilepsy is yangming failure to close and vital activity loss control， so a therapeutic approach focused on restoring the closure of yangming and regaining vital activity was proposed for the treatment of epilepsy. For excess syndrome， the treatment focuses on draining excess and descending qi， promoting purgation and restoring spirit. When yangming dryness-heat predominates， the approach involves unblock the bowels and regulating the spirit， descending qi and reducing fire， with modified Chengqi Decoction （承气汤） as prescription； when yangming phlegm-fire predominates， the treatment focuses on clearing heat and resolving phlegm， calming mind and suppressing fright， with modified Qingxin Wendan Decoction （清心温胆汤） as prescription； when yangming blood stasis predominates， the approach involves breaking up blood stasis and promoting purgation， eliminating stasis and awakening the mind， with Taoren Chengqi Decoction （桃核承气汤） as prescription. For deficiency syndrome， the treatment emphasizes tonifying deficiency and raising qi， strengthening the stomach and nourishing the spirit. When center qi deficiency and sinking of clear qi of the nutrients from food， the approach involves replenishing and uplifting qi while nourishing vital activity， with modified Liujunzi Decoction （六君子汤） as prescription； when yin deficiency and fluid consumption， the treatment focuses on nourishing stomach and tonifying yin， promoting fluid production and calming the spirit， with modified Maimendong Decoction （麦门冬汤） combined with Yiwei Decoction （益胃汤） as prescriptions. In clinical situations of deficiency-excess complex， it is essential to distinguish the primary condition from the secondary， applying both supplementing and draining methods flexibly to achieve optimal treatment.

Pathogenic microorganisms are direct causative agents of zoonotic infectious diseases,po-sing severe threats to the livestock industry by inducing massive animal mortality,economic losses in livestock products,and significant risks to human health.The CRISPR/Cas system has been widely adopted in nucleic acid detection of pathogenic microorganisms due to its unique trans-cleavage activity.By leveraging the superior optical properties of nanomaterials,researchers have integrated them with CRISPR/Cas systems to develop numerous visual biosensors,which not only significantly enhance signal output but also substantially reduce detection time and cost.This re-view focuses on five nanomaterials-graphene oxide(GO),gold nanoparticles(AuNPs),MoS2 nanosheets,metal-organic frameworks(MOFs),and quantum dots(QDs)—that have been exten-sively integrated with CRISPR/Cas systems in recent years.We systematically summarize their distinct physical characteristics and specific applications in CRISPR/Cas-based pathogen detection,followed by a concise comparison of the advantages and limitations of different methodologies.Fi-nally,we discuss the prospects for nanomaterials in CRISPR/Cas detection systems,aiming to pro-vide a valuable reference for advancing molecular diagnostics of pathogenic microorganisms.

AIM:To explore the core target and mechanism of α-Linolenic acid(ALA)in improving neuroinflammation through network pharmacology combined with in vitro experiments.METHODS:Pharmacological studies have shown that ALA has anti-inflammatory,antioxidant,and neuroprotec-tive properties.The targets of α-Linolenic acid were obtained from PharmMapper and Swiss Tar-get Prediction databases,the targets of neuroin-flammation were searched from GeneCards,TTD and OMIM databases,and the potential targets of ALA and neuroinflammation were obtained from Wayne diagram.Protein interaction network(pro-tein-protein interaction,PPI)of potential targets was constructed by STRING website,and the core targets in PPI were screened by Cytoscape 3.8.0 software.At the same time,potential targets are imported into DAVID database,GO and KEGG data were obtained and the results were visualized.Autodock vina and Pymol software were used to dock the selected core targets with ALA and visual-ize the results.An in vitro model of neuroinflamma-tion was constructed,and cell growth status,oxida-tive stress,and migration or repairing capacity were determined by CCK-8 analysis,SOD,MDA and cell scratches,and the expression of IL-6,iba 1,COX-2(PTGS2),and iNOS proteins was determined by ELISA or Western blot experiments.RESULTS:Network pharmacology analysis revealed 46 poten-tial targets of ALA for neuroinflammation,and 10 core targets,including IL-6 and PTGS 2.With 232 entries enriched by GO enrichment analysis and 70 signaling pathways enriched by KEGG enrichment analysis,molecular docking showed that ALA can form hydrogen bonding with COX-2.Experiments showed that ALA could improve cell viability,allevi-ate cell oxidative stress levels,and promote cell mi-gration and motor repair in an in vitro model of neuroinflammation.CONCLUSIONS:ALA may im-prove neuroinflammation by alleviating oxidative stress and inhibiting IL-6 and COX-2 protein expres-sion.

Objective:To assess the risk factors affecting development of non-tumor- related anastomotic stenosis after rectal cancer and to construct a nomogram prediction model.Methods:This was a retrospective study of data of patients who had undergone excision with one-stage intestinal anastomosis for rectal cancer between January 2003 and September 2018 in Nanfang Hospital of Southern Medical University. The exclusion criteria were as follows: (1) pathological examination of the operative specimen revealed residual tumor on the incision margin of the anastomosis; (2) pathological examination of postoperative colonoscopy specimens revealed tumor recurrence at the anastomotic stenosis, or postoperative imaging evaluation and tumor marker monitoring indicated tumor recurrence; (3) follow-up time <3 months; and (4) simultaneous multiple primary cancers. Univariate analysis using the χ 2 or Fisher's exact test was performed to assess the study patients' baseline characteristics and variables such as tumor-related factors and surgical approach ( P<0.05). Multivariate analysis using binary logistic regression was then performed to identify independent risk factors for development of non-tumor-related anastomotic stenosis after rectal cancer. Finally, a nomogram model for predicting non-tumor-related anastomotic stenosis after rectal cancer surgery was constructed using R software. The reliability and accuracy of this prediction model was evaluated using internal validation and calculation of the area under the curve of the model's receiver characteristic curve (ROC). Results:The study cohort comprised 1,610 patients, including 1,008 men and 602 women of median age 59 (50, 67) years and median body mass index 22.4 (20.2, 24.5) kg/m2. Non-tumor-related anastomotic stenosis developed in 121 (7.5%) of these patients. The incidence of non-tumor-related anastomotic stenosis in patients who had undergone neoadjuvant chemotherapy, neoadjuvant radiotherapy, and surgery alone was 11.2% (10/89), 26.4% (47/178), and 4.8% (64/1,343), respectively. Neoadjuvant treatment (neoadjuvant chemotherapy: OR=2.455, 95%CI: 1.148–5.253, P=0.021; neoadjuvant chemoradiotherapy, OR=3.882, 95%CI: 2.425–6.216, P<0.001), anastomotic leakage (OR=7.960, 95%CI: 4.550–13.926, P<0.001), open laparotomy (OR=3.412, 95%CI: 1.772–6.571, P<0.001), and tumor location (distance of tumor from the anal verge 5–10 cm: OR=2.381, 95%CI:1.227–4.691, P<0.001; distance of tumor from the anal verge <5 cm: OR=5.985,95% CI: 3.039–11.787, P<0.001) were identified as independent risk factors for non-tumor-related anastomotic stenosis. Thereafter, a nomogram prediction model incorporating the four identified risk factors for development of anastomotic stenosis after rectal cancer was developed. The area under the curve of the model ROC was 0.815 (0.773–0.857, P<0.001), and the C-index of the predictive model was 0.815, indicating that the model's calibration curve fitted well with the ideal curve. Conclusion:Non-tumor-related anastomotic stenosis after rectal cancer surgery is significantly associated with neoadjuvant treatment, anastomotic leakage, surgical procedure, and tumor location. A nomogram based on these four factors demonstrated good discrimination and calibration, and would therefore be useful for screening individuals at risk of anastomotic stenosis after rectal cancer surgery.

Gas therapy is emerging as a highly promising therapeutic strategy for cancer treatment. However, there are limitations, including the lack of targeted subcellular organelle accuracy and spatiotemporal release precision, associated with gas therapy. In this study, we developed a series of photoactivatable nitric oxide (NO) donors NRh-R-NO (R = Me, Et, Bn, iPr, and Ph) based on an N-nitrosated upconversion luminescent rhodamine scaffold. Under the irradiation of 808 nm light, only NRh-Ph-NO could effectively release NO and NRh-Ph with a significant turn-on frequency upconversion luminescence (FUCL) signal at 740 nm, ascribed to lower N-N bond dissociation energy. We also investigated the involved multistage near-infrared-controlled cascade release of gas therapy, including the NO released from NRh-Ph-NO along with one NRh-Ph molecule generation, the superoxide anion O₂^⋅- produced by the photodynamic therapy (PDT) effect of NRh-Ph, and highly toxic peroxynitrite anion (ONOO^‒) generated from the co-existence of NO and O₂^⋅-. After mild nano-modification, the nanogenerator (NRh-Ph-NO NPs) empowered with superior biocompatibility could target mitochondria. Under an 808 nm laser irradiation, NRh-Ph-NO NPs could induce NO/ROS to generate RNS, causing a decrease in the mitochondrial membrane potential and initiating apoptosis by caspase-3 activation, which further induced tumor immunogenic cell death (ICD). In vivo therapeutic results of NRh-Ph-NO NPs showed augmented RNS-potentiated gas therapy, demonstrating excellent biocompatibility and effective tumor inhibition guided by real-time FUCL imaging. Collectively, this versatile strategy defines the targeted RNS-mediated cancer therapy.

Epilepsy is a disease of the central nervous system caused by excessive neuronal discharges in the brain,characterized by sudden,recurrent and self-limited onset. The brain's qi collateral and the brain neural network are highly correlated and internally consistent in terms of structure and function. The theory of "brain's qi collateral-abnormal collateral",which is centered on the structural disorder and dysfunction of brain's qi collateral leading to the poor circulation of brain's qi collateral,can comprehensively explain the related pathogenesis of epilepsy and the law of disease evolution,so it has important clinical value. Taking the pathogenic characteristics as an entry point and based on the theory of "brain's qi collateral-abnormal collateral",this paper argues that phlegm and qi stagnation,wind in the brain's qi collateral,and phlegm and blood stagnation damaging the brain's collaterals,as well as the structural and functional characteristics of brain's qi collateral that circulate bi-directionally are the key factors for epilepsy to present sudden,recurrent,and self-limited characteristics. According to the therapeutic principle of "Collaterals need to be unobstructed to function normally",it is proposed that the method of regulating the qi and collaterals should be used as the basic treatment principle throughout the treatment. In addition,the method of resolving phlegm and eliminating blood stasis is supplemented for different pathological changes,while combining the syndrome differentiation of zang-fu viscera and attaching importance to the accompanying symptoms of epileptic seizures,to regulate the brain's qi collateral to achieve the effects of wind quenching and epileptic arrest. This is to provide reference for the treatment of epilepsy in traditional Chinese medicine.

【Objective】 To analyze differences of eplets between the patient who generated HLA allele-specific antibodies after platelet transfusion with donors. 【Methods】 The HLA genotypes of the patient and donors were detected by PCR-SBT, and the Luminex single antigen beads coating was used to screen HLA-Ⅰ antibodies in the patient’s serum. HLA Matchmaker was utilized to analyze different amino acids and eplets. 【Results】 The patient carried HLA-A^*02∶03 allele, and HLA-A2 antibodies were found in his serum after platelet transfusion (A^*02∶01, A^*02∶06, and A^*02∶07). Sequence alignment showed that the patient′s A^*02∶03 has a difference in position 149, which resulted in a different eplet between A^*02∶03 and A^*02∶01, A^*02∶06, A^*02∶07 and then induced the production of antibodies. 【Conclusion】 HLA antibodies are specific for HLA epitopes that have structural differences due to amino acid differences between HLA alleles, suggesting that high-resolution typing of HLA-A, -B need to be conducted in patients and donors, and the acceptable mismatch of HLA should be determined based on epitopes rather than antigens, so as to reduce alloimmune response and improve platelet count after transfusion.
