Objective:To explore the clinical efficacy of autologous platelet-rich plasma (PRP) in the treatment of acute injury to the anterior talofibular ligament (ATFL).Methods:A retrospective study was conducted to analyze the data of 96 patients who had been admitted to Department of Orthopedic Trauma Repair, The Nanhua Hospital Affiliated to Hengyang Medical School for acute ATFL injuries of grades Ⅰ & Ⅱ from January 2022 to December 2023. They were divided into 2 groups according to their different treatments. In the PRP group subjected to local PRP injection combined with conservative treatment, there were 49 patients (28 males and 21 females), with an age of (32.5±6.5) years. In the conservative group subjected to traditional conservative treatment, there were 47 patients (24 males and 23 females), with an age of (30.5±5.3) years. The 2 groups were compared in terms of visual analog scale (VAS) pain scores, talar anterior translations, Karlsson scores, American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scores before and 6 months after treatment.Results:No statistically significant differences were observed in the baseline characteristics between the 2 groups before treatment, indicating comparability ( P>0.05). All patients were followed up for (9.1±1.7) months. In both groups, the VAS pain scores significantly decreased after treatment than the pre-treatment ones, the talar anterior translations significantly reduced after treatment than the pre-treatment ones, and the AOFAS and Karlsson scores significantly increased after treatment than the pre-treatment ones ( P < 0.05). After 6 months of treatment, the talar translation distance [(2.5±0.4) mm], AOFAS ankle hind foot score [(91.7 ± 4.0) points], and Karlsson score [(93.0±3.5) points] in the PRP group were significantly better than those in the conservative group [(6.1±0.9) mm, (87.1±4.3) points, (89.0±4.0) points]( P < 0.05). Conclusion:In the treatment of acute ATFL injury, PRP therapy demonstrates good clinical efficacy, for it can significantly reduce pain, promote functional recovery, and improve joint stability.

Objective:To explore the efficacy and safety of type A botulinum toxin (BTX-A) in alleviating pain and reducing capsular contracture after breast augmentation surgery.Methods:This single-center, double-blind, and randomized controlled trial included 212 female patients who underwent breast augmentation surgery at Changsha YaMei Medical Cosmetic Hospital from May 2020 to January 2021. Patients were divided into two groups according to whether BTX-A was injected into the pectoralis major during the augmentation: 106 in the BTX-A group, with an average age of (33.1±3.8) years; and 106 in the control group, with an average age of (33.3±3.5) years. The visual analogue scale (VAS) was used to assess pain on days 1, 3 and 7 post-operation. After two years of follow-up, the postoperative VAS scores, duration of pain, rates of capsular contracture, and incidence of adverse reactions were compared between the two groups.Results:One case was lost to follow-up in each group. On postoperative days 1 and 3, the VAS scores of the BTX-A group were (3.93±1.77) and (5.35±2.04) scores, respectively, lower than those of the control group, which were (5.93±2.17) and (7.34±1.75) scores (both P<0.001). On day 7, the scores were (1.96±1.71) and (2.26±1.90) scores, respectively, with no statistically significant difference ( P=0.225). The pain severity in both groups showed a trend of initial increase followed by a decrease, with a significant difference ( P<0.001). The duration of pain in the BTX-A group was (2.6±1.8) days, shorter than that in the control group (4.9±2.1) days, with a statistically significant difference ( P<0.001). The rate of capsular contracture in the BTX-A group was 0.95% (1/105), compared to 1.90% (2/105) in the control group, with no statistically significant difference ( P=1.000). The incidence of adverse reactions was 11.32% (12/106) in the BTX-A group and 10.38% (11/106) in the control group, with no statistically significant difference ( P=0.825). There were no severe adverse reactions such as respiratory or cardiovascular events or deaths in either group. Conclusion:BTX-A can alleviate pain after breast augmentation surgery with high safety. However, it does not have a significant advantage in preventing capsular contracture.

Objective To explore the effects and mechanisms of Changpu Yujin Tang(CPYJT)on the NOD-like receptor thermal protein domain associated protein 3/cysteinyl aspartate specific proteinase-1/Gasdermin D(NLRP3/Caspase-1/GSDMD)signaling pathway-mediated neuroinflammation in rats with Tourette syndrome(TS).Methods SPF-grade male SD rats were randomly divided into the Control and TS groups.After successful modeling in the TS group,the rats were randomly divided into the Model,Tiapride,and CPYJT groups,and were treated with the corresponding drugs for 4 weeks.After the treatment,the rats' behavior was scored,H & E staining was used to observe pathological changes in the striatum,ELISA was used to measure the content of IL-1β and IL-18,RT-qPCR was used to detect the expression of NLRP3 and ASC mRNA,and Western blot was used to detect the expression of NLRP3,ASC,Caspase-1,Cleaved-Caspase-1,GSDMD,and GSDMD-NT proteins.Results Compared with the Control group,the Model group showed increased scores of stereotyped and motor behaviors(P＜0.01),pathological changes in the striatal tissue,increased content of IL-1β and IL-18(P＜0.01),and upregulated expression of NLRP3,ASC mRNA,and NLRP3,ASC,Caspase-1,Cleaved-Caspase-1,GSDMD,and GSDMD-NT proteins(P＜0.01).Compared with the Model group,the Tiapride group and the CPYJT group showed decreased scores of stereotyped and motor behaviors(P＜0.01),improved pathological damage in the striatal tissue,reduced content of IL-1β and IL-18(P＜0.01),and inhibited expression of NLRP3,ASC mRNA,and NLRP3,ASC,Caspase-1,Cleaved-Caspase-1,GSDMD,and GSDMD-NT proteins(P＜0.01).Conclusion The therapeutic effect of CPYJT on TS is related to the inhibition of the neuroinflammatory response mediated by the NLRP3/Caspase-1/GSDMD signaling pathway.

Objective : To investigate the effect of isoprene cysteine carboxymethyltransferase (ICMT) gene on the migration and invasion of salivary adenoid cystic cancer cells (SACC) and the related mechanism, to provide experimental evidence for molecular targeted therapy of SACC. Methods: Adenoid cystic cancer cells SACC-LM and SACC-83 were cultured in vitro, and siRNA was transfected into human SACC-LM and SACC-83 cells (experimental group) by transient transfection of a liposome vector. A blank control group and negative control group were set up respectively (transfected NC-siRNA). qRT-PCR was peformed to measure the mRNA expression of ICMT and RhoA in each group after transfection and to determine the silencing efficiency. The expression of ICMT, membrane RhoA, total RhoA, matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9) and Rho associated with coiled helical binding protein kinase 1 (ROCK1) in each group was detected by Western blot. The proliferation abilityies of SACC cells was detected by CCK-8 assay. The migration and invasion ability of SACC cells were detected by comparing the relative healing area of cell scratch assay and the number of Transwell assay cells. Results: After transfection of ICMT-siRNA into SACC-LM and SACC-83 cells, the expression of ICMT gene and protein in the experimental group was significantly decreased compared with the negative control group and blank control group (P<0.05), but there were no significant differences in the expression of RhoA gene and total protein among all groups (P>0.05). The expression of RhoA membrane proteins, ROCK1, MMP-2, MMP-9 in the experimental group was significantly decreased compared with that in the negative control group and blank control group (P<0.05). Cell proliferation ability was significantly decreased (P<0.05). The migration and invasion abilities were significantly decreased (P<0.05). Conclusion In vitro silencing of ICMT gene can effectively inhibit the migration and invasion of human SACC-LM and SACC-83 cells, and the mechanism may be related to RhoA-ROCK signaling pathway.
