RESUMEN
ObjectiveTo observe the effect of enriched environment (EE) combined with acupuncture at head point (HA) on behavior in rats with autism spectrum disorder. MethodsHealthy female Wistar rats were given peritoneal injection of sodium valproate at 12.5 days of gestation. Twenty-four male offspring rats were randomly selected and then randomly divided into model group (n = 6), EE group (n = 6), HA group (n = 6) and EE combined with HA group (the combined group, n = 6). Six male offspring rats born from female mice injected with the same amount of saline intraperitoneally were as control group. After four weeks of treatment, all the five groups were tested with three-chamber test and marble burying test, and the sociability index, the social novelty index and the number of buried marbles were recorded. The levels of interleukin (IL)-1β and IL-6 in peripheral blood were determined by enzyme-linked immunosorbent assay (ELISA). ResultsAfter treatment, compared with the model group, the sociability index and the social novelty index improved (P < 0.05), the number of buried marbles reduced (P < 0.05), and the levels of IL-6 and IL-1β in peripheral blood decreased in EE group, HA group and the combined group (P < 0.05); while the combined group was the best (P < 0.01). ConclusionBoth EE or acupuncture at HA could improve behavioral symptoms, and reduce the expression of inflammatory factors in rats with autism spectrum disorder. The combination of the two methods showed the best result.
RESUMEN
BACKGROUND:Hyperuricemia is a common metabolic disease,and the main clinical manifestation of patients with hyperuricemia is the formation of uric acid crystals leading to gout.Previous studies have only reported that uric acid crystals lead to intervertebral disc degeneration,but there are fewer studies on the correlation between hyperuricemia and intervertebral disc degeneration. OBJECTIVE:To retrospectively analyze the characteristics of intervertebral disc degeneration in patients with hyperuricemia and the correlation between serum uric acid level and intervertebral disc degeneration. METHODS:A retrospective analysis was performed in all patients diagnosed with intervertebral disc degeneration admitted at the Department of Orthopedics,the Affiliated Hospital of Southwest Medical University from January 2021 to December 2022.There were 97 hyperuricemia patients in the hyperuricemia group and 194 non-hyperuricemia patients in the control group according to sex and age in a ratio of 1:2.Blood uric acid test results were collected,and Pfirrmann scoring was performed for the degree of disc degeneration in patients based on the whole spinal MRI images.The difference in the degree of disc degeneration between the two groups was compared,and the correlation between the serum uric acid level and the degree of intervertebral disc degeneration was analyzed. RESULTS AND CONCLUSION:The Pfirrmann score in the hyperuricemia group was higher than that in the control group,and the total number of disc degeneration in the hyperuricemia group was also significantly higher than that in the control group(P<0.05).Spearman correlation analysis showed that the degree of disc degeneration in male patients was positively correlated with serum uric acid level at many spinal segments in the hyperuricemia group(C3/4:r=0.317,C4/5:r=0.333,C5/6:r=0.309,L2/3:r=0.443,P<0.05);the degree of disc degeneration in female patients was also positively correlated with serum uric acid level(C3/4:r=0.354,C4/5:r=0.388,C6/7:r=0.312,T7/8:r=0.282,T9/10:r=0.305,T11/12:r=0.277,L4/5:r=0.319,L5-S1:r=0.367,P<0.05).In the control group,there was no significant correlation between the degree of disc degeneration and serum uric acid level in male and female patients(P>0.05).To conclude,in patients with hyperuricemia,the higher serum uric acid level indicates the more serious intervertebral disc degeneration.Therefore,hyperuricemia is one of the risk factors for intervertebral disc degeneration.
RESUMEN
Objective To identify and validate co-expressed genes associated with myocardial ischemia/reperfusion injury(MI/RI)and necrotic apoptosis by bioinformatics analysis.Methods Gene expression profile data for MI/RI were obtained by GSE67308 and GSE19875 datasets from the Gene Expression Omnibus(GEO)database.Differential expression analysis was conducted on the GSE67308 dataset to identify differentially expressed genes(DEGs),followed by gene set enrichment analysis and biological pathway analysis.More-over,immune cell infiltration analysis was performed on the GSE67308 dataset.Necrotic apoptosis-related genes were retrieved from the Molecular Signatures Database and the Kyoto Encyclopedia of Genes and Genomes(KEGG).A protein-protein interaction(PPI)network was constructed by overlapping DEGs with these necrotic apoptosis-related genes to identify key genes.Furthermore,the expression pat-terns of these key genes across various cardiac cell types were analyzed using a single-cell sequencing analysis platform,and validation of key gene expression was performed using the GSE19875 dataset.Results A total of 1054 DEGs were identified,comprising 363 upregu-lated and 691 downregulated genes.Gene enrichment analysis revealed that DEGs were primarily associated with processes related to apoptosis,immune responses,and intracellular signaling regulation.Moreover,biological pathway analysis demonstrated that DEGs were predominantly involved in the regulation of signaling pathways such as tumor necrosis factor(TNF)and NF-κB.Immune infiltration anal-ysis indicated a high degree of immune infiltration,particularly with natural killer cells and monocytes,in MI/RI myocardial tissue.PPI network analysis identified Il1b,TNF,Birc3,and Ripk1as crucial genes in the context of necrotic apoptosis.Single-cell sequencing anal-ysis showed the elevated expression of key genes within white blood cells.In comparison to the control group,the MI/RI model group in the GSE19875 dataset exhibited significantly increased expression of Il1b,TNF,Birc3,and Ripk1(P<0.01).Conclusion MI/RI is strongly correlated with the TNF signaling pathway and the NF-κB signaling pathway,both of which play pivotal roles in regulating necrotic apop-tosis.Il1b,TNF,Birc3,and Ripk1emerge as key genes that concurrently regulate both MI/RI and necrotic apoptosis.It is plausible that IL-1b,TNF,Birc3,and Ripk1 may serve as critical regulatory factors in the context of necrotic apoptosis during MI/RI.
RESUMEN
Objective To explore the effects of different acupoints,different target organs,and different interventions on acupoint efficacy based on ACU&MOX-DATA platform;To illustrate and visualize whether the above factors have the characteristics of"specific effect"or"common effect"of acupoint efficacy.Methods The multi-source heterogeneous data were integrated from the original omics data and public omics data.After standardization,differential gene analysis,disease pathology network analysis,and enrichment analysis were performed using Batch Search and Stimulation Mode modules in ACU&MOX-DATA platform under the conditions of different acupoints,different target organs,and different interventions.Results Under the same disease state and the same intervention,there were differences in effects among different acupoints;under the same disease state,the same acupoint and intervention,the responses produced by different target organs were not completely consistent;under the same disease state and acupoint,there were differences in effects among different intervention measures.Conclusion Based on the analysis of ACU&MOX-DATA platform,it is preliminary clear that acupoints,target organs,and interventions are the key factors affecting acupoint efficacy.Meanwhile,the above results have indicated that there are specific or common regulatory characteristics of acupoint efficacy.Applying ACU&MOX-DATA platform to analyze and visualize the critical scientific problems in the field of acupuncture and moxibustion can provide references for deepening acupoint cognition,guiding clinical acupoint selection,and improving clinical efficacy.
RESUMEN
Objective:To delineate the morphological features of pedicle-facet joints in lumbar spondylolysis patients, correlating these with spinopelvic parameters to explore their mechanisms and clinical implications.Methods:This study enrolled 121 patients with L 5 spondylolysis (IS group), 108 with L 4, 5 degenerative spondylolisthesis (DS group), and 100 with normal L 4, 5 but L 5S 1 lumbar disc herniation (NL group), who underwent radiography and multislice spiral CT from May 2020 to January 2023. Parameters including vertebral slip percentage (SP) and spinopelvic alignments, such as sacral slope and lumbar lordosis, were quantified using standing lateral lumbar radiographs. Morphological parameters of the L 4 and L 5 facet joints were measured on 3D reconstructed lumbar CT images, including the facet joint angle (FJA), pedicle-facet joint angle (PFA), facet joint osteoarthritis (OA), and facet joint tropism (FT). Results:The analysis revealed significant variances in SS and LL among the groups ( F=21.910, P<0.001; F=22.439, P<0.001). The IS group exhibited the highest SS and LL, followed by the DS and NL groups. Morphological assessments showed the largest L 4 FJA in the IS group, with progressive decreases in the DS and NL groups ( F=344.791, P<0.001). Conversely, L 4 PFA was greatest in the DS group ( F=193.725, P<0.001). Notably, L 4 OA was markedly more severe in the DS group compared to IS and NL groups ( H=467.925, P<0.001), with no significant disparity between IS and NL groups ( P>0.05). Correlation analyses within each cohort highlighted a negative association of sacral slope and lumbar lordosis with facet joint angles, yet a positive correlation with pedicle-facet joint angles both with statistical significance ( P<0.05). Furthermore, L 4 facet joint angles were consistently smaller than those at L 5, and L 4 pedicle-facet joint angles were larger than L 5 ( P<0.05). Osteoarthritis at L 5 was more pronounced in the IS group compared to L 4 ( Z=7.043, P<0.001), a trend inversely observed in the DS group ( Z=11.868, P<0.001), while the NL group showed no significant osteoarthritic variance between levels ( Z=0.556, P=0.578). Conclusion:Patients with lumbar spondylolysis demonstrate elevated sacral slope and lumbar lordosis, indicative of increased localized biomechanical stress in the lumbar spine. These alterations in the morphology of the pedicle-facet joints highlight the distinctive structural adaptations and potential strain distributions within this cohort.
RESUMEN
Objective:To observe the morphological characteristics of L 4, 5 facet joints in patients with degenerative lumbar spondylolisthesis (DLS) of different spinopelvic types based on Roussouly classification. Methods:We retrospectively analyzed 142 patients with DLS who visited the department of orthopaedics in the Affiliated Hospital of Southwest Medical University from August 2018 to May 2022. There were 33 males aged 65.0±10.7 years and 109 females aged 61.8±9.6 years. The following morphological parameters of the L 4, 5 facet joint were measured on the CT images: facet joint angle (FJA), pedicle facet angle (PFA), facet joint tropism (FT) and facet joint osteoarthritis (OA) degree; the sacral slope (SS), lumbar lordosis (LL) and percentage of L 4 slip distance (SDP) were measured on preoperative standing neutral lumbar radiographs. According to the Roussouly classification, the patients were divided into four groups (type I, type II, type III, and type IV). The differences of morphological parameters of the facet joints and SDP were compared among the four groups, and the correlation between the FJA and PFA was analyzed. Results:There were 142 patients, including 28 type I, 50 type II, 43 type III, and 21 type IV according to the Roussouly classification. The SDPs of type I, type II, type III, and type IV were 19.1%±3.4%, 18.6%±3.9%, 21.7%±3.9%, 25.0%±2.4%, respectively. Except for types I and II, there were statistically significant differences in pairwise comparison among all other types ( P<0.05). The FJAs in type I and type II (31.4°±6.3°, 35.2°±6.8°) were larger than those in type III (28.4°±5.6°) and type IV (23.4°±4.5°), and the FJA in type III was larger than that in type IV. Conversely, the FJA in type I was smaller than that in type II. These differences were statistically significant ( P<0.05). The PFAs in type I and type II (113.9°±4.9°, 111.3°±5.6°) were smaller than those in type III (116.3°±4.4°) and type IV (121.8°±3.5°), and the PFA in type III was smaller than that in type IV, while, the PFA in type I was larger than that in type II. These differences were statistically significant ( P<0.05). The degree of OA in both type I and type II was lower than that in type III and type IV, with statistically significant differences ( P<0.05). However, there were no statistically significant differences in the degree of OA between type I and type II and between type III and type IV ( P> 0.05). Additionally, there were no statistically significant differences ( F=0.40, P=0.752) in the FT values among type I, type II, type III, and type IV (5.8°±2.3°, 5.6°±2.4°, 6.1°±1.8°, 5.9°±1.9°). Pearson correlation analysis showed that FJA was negatively correlated with PFA ( r=-0.68, P<0.001). Conclusion:In the slip segment of DLS, the facet joint morphology was part of the joint configuration in different spinopelvic types, not just the result of joint remodeling after DLS. Morphological characteristics of the facet joints and DLS interacted with each other.

RESUMEN
Intersphincteric resection (ISR) surgery increases the rate of anal sphincter preservation in patients with ultra-low rectal cancers. However, the anastomotic site of ISR surgery is at risk for structural healing complications such as anastomotic leakage, anastomotic dehiscence, secondary anastomotic stenosis, chronic presacral sinus, rectovaginal fistula, and rectourethral fistula, which can lead to a persistent defunctioning ostomy or a secondary permanent colostomy. This article systematically describes the preoperative high-risk factors and characteristics of anastomotic site structural healing complications after ISR surgery, as well as the management of the anastomotic site during various stages including hospitalization, from discharge to one month after surgery, from one month after surgery to before stoma reversal, and after stoma reversal. This is to provide a clearer understanding of the risks associated with the anastomotic site at different stages of the healing process and to timely detect and actively manage related complications, thereby reducing the rate of permanent colostomy and truly achieving the dual goals of "survival benefit" and "quality of life improvement" in ISR surgery.

The China PelvEx Collaborative, under the direction of Colorectal Cancer Committee of the Chinese Medical Doctor Association, Gastrointestinal Surgery Committee of China International Exchange and Promotive Association for Medical and Health, has formulated and issued the Chinese expert consensus for primary rectal cancer beyond total mesorectal excision planes and locally recurrent rectal cancer (2023 edition) , with the academic support of the Chinese Journal of Gastrointestinal Surgery and Chinese Journal of Colorectal Disease (Electronic Edition). This Consensus refers to the expert consensus developed by the International PelvEx Collaboration, incorporates the latest international multi-center research results and combines the latest research results in China. The Consensus unifies some definitions, clarifies the surgical indications, and puts forward the definition and preventive measures of "empty pelvic syndrome" earlier. For the controversial classification of local recurrent rectal cancer, the Chinese classification was proposed for the first time in Consensus. At the same time, the definition of pelvic exenteration is controversial, and a more consistent cognition is proposed. It is believed that, with the in-depth research on complicated rectal cancer, C-PelvEx will gather more higher-level data from clinical research in several domestic centers, so as to further enrich the content of the updated Consensus.

Objective: To explore the feasibility, safety, and short- and long-term efficacy of laparoscopic pelvic exenteration (LPE) in treating locally advanced rectal cancer. Methods: The clinical data of 173 patients who had undergone pelvic exenteration (PE) for locally advanced rectal cancer that had been shown by preoperative imaging or intraoperative exploration to have invaded beyond the mesorectal excision plane and adjacent organs in the Cancer Hospital, Chinese Academy of Medical Sciences (n=64) and Peking University First Hospital (n=109) from 2010 January to 2021 December were collected retrospectively. Laparoscopic PE (LPE) had been performed on 82 of these patients and open PE (OPE) on 91. Short- and long-term outcomes (1-, 3-, and 5-year overall and disease-free survival and 1- and 3-year cumulative local recurrence rates) were compared between these groups. Results: The only statistically significant difference in baseline data between the two groups (P>0.05) was administration of neoadjuvant therapy. Compared with OPE, LPE had a significantly shorter operative time (319.3±129.3 minutes versus 417.3±155.0 minutes, t=4.531, P<0.001) and less intraoperative blood loss (175 [20-2000] ml vs. 500 [20-4500] ml, U=2206.500, P<0.001). The R0 resection rates were 98.8% and 94.5%, respectively (χ2=2.355, P=0.214). At 18.3% (15/82), and the incidence of perioperative complications was lower in the LPE group than in the OPE group (37.4% [34/91], χ2=7.727, P=0.005). The rates of surgical site infection were 7.3% (6/82) and 23.1% (21/91) in the LPE and OPE group, respectively (χ2=8.134, P=0.004). The rates of abdominal wound infection were 0 and 12.1% (11/91) (χ2=10.585, P=0.001), respectively, and of urinary tract infection 0 and 6.6% (6/91) (χ2=5.601, P=0.030), respectively. Postoperative hospital stay was shorter in the LPE than OPE group (12 [4-60] days vs. 15 [7-87] days, U=2498.000, P<0.001). The median follow-up time was 40 (2-88) months in the LPE group and 59 (1-130) months in the OPE group. The 1-, 3-, and 5-year overall survival rates were 91.3%, 76.0%, and 62.5%, respectively, in the LPE group, and 91.2%, 68.9%, and 57.6%, respectively, in the OPE group. The 1, 3, and 5-year disease-free survival rates were 82.8%, 64.9%, and 59.7%, respectively, in the LPE group and 76.9%, 57.8%, and 52.7%, respectively, in the OPE group. The 1- and 3-year cumulative local recurrence rates were 5.1% and 14.1%, respectively, in the LPE group and 8.0% and 15.1%, respectively, in the OPE group (both P>0.05). Conclusions: In locally advanced rectal cancer patients, LPE is associated with shorter operative time, less intraoperative blood loss, fewer perioperative complications, and shorter hospital stay compared with OPE. It is safe and feasible without compromising oncological effect.

Objective:To explore the application research of isolated esophageal ventilation device in painless gastroscopy.Methods:A total of 200 patients who underwent painless gastroscopy requiring esophageal isolation were selected,and they were randomly divided into an observation group(isolated esophageal ventilation device + gastroscopy)and a control group(ordinary mask ventilation + gastroscopy),with 100 cases in each group.The heart rates,blood pressures,the numbers of breaths and blood oxygen saturation(SpO2)of 5 time points of two groups were recorded at entering time(T0),pre installing ventilation device(T1),post installing ventilation device(T2),during gastroscopy(T3)and post gastroscopy(T4).And then,the incidence of complications,occurrence of adverse events,total dosages of Propofol,operation times of gastroscopy,wake-up times and observation times of two groups were compared.Patients'satisfactions for the examination were evaluated by self-designed satisfaction survey and evaluation scale.Results:The differences of SpO2 between the two groups of patients at T1-T4 time points were statistically significant(t=23.150,t=14.720,t=17.900,t=18.520,P<0.05),respectively,and the difference of that between two groups at T0 time point was not statistically significant.There were no significant differences in blood pressure,heart rate and respiratory frequency between the two groups of patients at different time points.The total incidences of complications in the control group and the observation group were respectively 68.00% and 13.00%.The total incidence of complications in the control group was significantly higher than that in the observation group,and the difference was statistically significant(x2=62.766,P<0.05).The total dosage of Propofol,time of gastroscopy examination and observation time of the observation group were significantly lower than those of the control group,and the differences were statistically significant(t=4.977,t=20.040,t=6.486,P<0.05),respectively.There was no statistically significant difference in the wake-up time between the two groups of patients.The satisfaction rates of the control group and observation group were respectively 79.00% and 95.00%for painless gastroscopy,and the satisfaction rate of the control group was significantly lower than that of the observation group,and the difference was statistically significant(x2=11.317,P<0.05).Conclusion:In the application of the isolated esophageal ventilation device in painless gastroscopy,the SpO2 decrease of preventive operation can improve the oxygenation state of patients,and decrease the incidence rate of chocking cough and other adverse reactions,and reduce the occurrence of gastric reflux,and shorten the time of gastroscopy examination,and enhance the satisfaction of patients for examination,which has better safety.
RESUMEN
Objective To explore whether PI3K inhibitor combined with oncolytic virus can play an effective oncolytic effect on osteosarcoma. Methods The cytotoxicity to tumor cells was detected by MTT method, and the mechanism of enhancing the anti-tumor activity was explored by observation of the swelling of endoplasmic reticulum using electron microscope and the expression of apoptosis-related proteins using Western blotting. The tumor clearance ability of the combination of the PI3k inhibitor ZSTK474 and vesicular stomatitis virus A51 (VSVA51) was verified by anti-tumor experiment in vivo. The apoptosis of tumor cells was verified by immunohistochemistry. Results PI3K inhibitor could be used as sensitizers of oncolytic VSVA51, and confirmed that the)' promoted the strong apoptosis of osteosarcoma cells by aggravating the stress of endoplasmic reticulum in tumor cells (P < 0 . 01). In vivo experiments also showed that PI3K inhibitors combined with VSVA51 could significantly promote the oncolytic effect of osteosarcoma (P<0.001), and this combination therapy enhanced the infiltration of immune cells in the tumor (P<0.001). Conclusion PI3K inhibitors combined with oncolytic virus is a potential therapy for osteosarcoma.
RESUMEN
Objective: To evaluate the safety and efficacy of distal rectal transection by using transanterior obturator nerve gateway (TANG) in laparoscopic radical resection for lower rectal cancers. Methods: A descriptive case series study was performed. Inclusion criteria: (1) patients with primary rectal adenocarcinoma, with the distance of 3-5 cm from tumor to anal verge, with normal anal function before surgery and a desire to preserve anus; (2) laparoscopic radical resection of rectal cancer was performed and the distal rectum was transected using TANG approach. Exclusion criteria: (1) patients with distant metastasis or receiving palliative surgery; (2) the distal rectum was transected using non-TANG approach; (3) patients receiving combined multiple organs resection; (4) patients complicated with other tumors requiring additional treatment during the study. Clinicopathological data of 50 patients with low rectal cancer undergoing laparoscopic resection using TANG approach between January 2019 and December 2020 in Peking University First Hospital were retrospectively collected. Perioperative conditions, length of specific pelvic lines, additional angle and postoperative short-term outcomes were observed and described. Additional angle was defined as the angle between the simulated stapling line with the traditional approach and the real stapling line with the TANG approach. Data following normal distribution were presented as Mean±SD, or M [quartile range (Q(R))] otherwise. Results: All the patients successfully completed laparoscopic surgery without transferring to open or transanal surgery. The median operative time was 193 (80) min and blood loss was 50 (58) ml. All tumors received R0 resection with the distance from the tumor to distal resection margin of 1.7 (0.4) cm and the anastomotic height of 2.0 (0.1) cm. Rectal transection was completed by one cartridge in 52.0% of the cases (26/50) and two cartridges in 48.0% (24/50). Length of the stapling line was 6.6 (1.5) cm. The time to construct the gateway was 8.0 (6.0) min. The vessel damage occurred in 4.0% of the cases (2/50) and none of the cases encountered obturator nerve damage. Inlets of the pelvis in TANG and traditional approach were (9.9±1.3) cm vs. (7.2±1.1) cm (t=24.781, P<0.001). Additional angle of TANG was (15±2) °. The transecting positions on the midline and right edge of the rectum specimen by TANG were 0.6 (0.2) cm and 1.0 (0.2) cm lower than those by the traditional approach. One case (2.0%) died of pulmonary infection on the 17th day after surgery, 2 cases (4.0%) received re-operation and 14 cases (28.0%) had postoperative complications, including anastomotic leakage (7/50, 14.0%), urinary retention (6/50, 12.0%), pelvic infection (2/50, 4.0%) and ileus (2/50, 4.0%). The median postoperative hospital stay was 12 (6) days. Conclusions: Laparoscopic distal rectal transection by using TANG approach is safe and effective in the treatment of low rectal cancer. As an alternative rectal transecting method, TANG has advantages especially for the obese and those with a contracted pelvis and ultralow rectal cancers.

Asiatic acid (AA) is a ursane pentacyclic triterpenoids, which possesses a wide range of pharmacological activities, such as anti-tumor, hypoglycemic, anti-inflammatory, anti-bacterial. Due to poor solubility and low bioavailability, clinical application of asiatic acid is limited. To address these defects, the structural modifications of AA have been carried out, and large numbers of AA-based derivatives with novel structure and eximious biological activity have been developed. In this paper, the research progress of structural modifications, biological activity, structure-activity relationship and mechanism studies in recent twenty years are reviewed, which provides reference for development of AA-related drugs.
RESUMEN
Objective To investigate the efficacy of acupuncture and rehabilitation therapy on lower limb motor function, and to explore a cortical mechanism using functional near infrared spectroscopy (fNIRS). Methods From December, 2020 to July, 2021, 24 stroke patients with lower limb motor dysfunction in our hospital were randomly divided into rehabilitation group (n = 12) and acupuncture-rehabilitation group (n = 12), and received routine rehabilitation training and acupuncture-rehabilitation intervention for four weeks, respectively. The control group included ten healthy subjects matched the patients. Before and after intervention, the lower limb motor function of the patients was assessed with Fugl-Meyer Assessment-Lower Extremities (FMA-LE), and all the subjects accepted fNIRS examination. The functional intensity and lateralization index (LI) of supplementary motor area (SMA), premotor cortex (PMC) and sensory motor cortex (SMC) were calculated based on oxygenated hemoglobin (HbO2). Results There was no significant difference in FMA-LE score between the rehabilitation group and the acupuncture-rehabilitation group before the intervention (P > 0.05). After four weeks of intervention, FMA-LE scores improved in both groups (t > 3.770, P 0.05). After intervention, the average functional connection increased in both groups (t > 2.178, P < 0.05), and the functional connection of the affected PMC of acupuncture-rehabilitation group increased (P < 0.05). The LI in SMC increased in the acupuncture-rehabilitation group (P < 0.05). There was a significant positive correlation between the change of functional connection of the affected PMC and the change of FMA-LE scores in the acupuncture-rehabilitation group (r = 0.579, P < 0.05). Conclusion Acupuncture with rehabilitation therapy can significantly improve the lower limb motor function and asymmetrical activation of SMC in stroke patients. The recovery of lower limb motor function may be related to the enhanced activation of affected PMC.
RESUMEN
PURPOSE: Although drug-coated balloon (DCB) treatment is known to be effective for de novo lesions, the influence of sex on angiographic and clinical outcomes remains unknown. This study aimed to investigate the angiographic and clinical impact of DCB treatment in patients with de novo coronary lesions according to sex. MATERIALS AND METHODS: A total of 227 patients successfully treated with DCB were retrospectively enrolled and divided into two groups according to sex. The primary endpoint was late lumen loss (LLL) at 6-month angiography, and the secondary endpoint was target vessel failure (TVF), which included cardiac death, target vessel myocardial infarction, target lesion revascularization, and target vessel thrombosis. RESULTS: The study enrolled 60 women (26.4%) and 167 men (73.6%). Compared to men, women had a smaller vessel size, larger DCB to reference vessel ratio, and more dissections after DCB treatment (55.0% vs. 37.1%, p=0.016). Women also had a significantly higher LLL compared to men (0.12±0.26 mm vs. 0.02±0.22 mm, p=0.012) at the 6-month follow-up angiography. During a median follow-up of 3.4 years (range 12.7-28.9 months), TVF was similar (women 6.7% vs. men 7.8%, p=0.944). In multivariable analysis, women were independently associated with a higher LLL. CONCLUSION: LLL was higher in women, but there was no difference in TVF between women and men. Based on multivariable analysis, the women sex was an independent predictor of higher LLL (Impact of Drug-coated Balloon Treatment in de Novo Coronary Lesion; NCT04619277).

OBJECTIVES: Although drug-coated balloons (DCBs) are established for de-novo lesions in small coronary arteries, the impact of DCB treatment according to the reference vessel diameter (RVD) remains poorly defined. This study aimed to evaluate the angiographic and long-term clinical outcomes of DCB treatment for de-novo coronary lesions according to RVD. METHODS AND RESULTS: A total of 227 patients were retrospectively enrolled and stratified according to an RVD >2.5 mm [nonsmall vessel disease (NSVD) group, n = 100] and ≤2.5 mm [small vessel disease (SVD) group, n = 127]. The primary endpoint was late lumen loss (LLL) at a 6-month follow-up, and the secondary endpoint was target vessel failure (TVF, a composite of cardiac death, target vessel myocardial infarction, target vessel revascularization and target vessel thrombosis). The LLL among the 206 patients (90.8%) returning for scheduled angiography at 6 month was similar (NSVD, 0.03 ± 0.22 mm vs. SVD, 0.06 ± 0.25 mm; P = 0.384). TVF was also comparable in both groups at a median follow-up of 3.4 years (NSVD, 7.0 vs. SVD, 7.9 %; P = 0.596). At baseline, there were numerically more dissections in the SVD group compared to the NSVD group (47.2 vs. 35.0 %; P = 0.064); however, most of these had disappeared in both groups at a 6-month follow-up. In a multivariable analysis, the presence of dissection was not associated with LLL or TVF in either group. CONCLUSIONS: The safety and efficacy of DCB treatment for de-novo coronary lesions, in terms of LLL and TVF, was unrelated to RVD.

Objective To develop an SNP Panel for East Asian population, which has a high individual identification rate and the capability of ancestry analysis. Methods The 55 SNP Panel by Professor KIDD of Yale University and the 128 SNP Panel by Professor SELDIN of Davis School of California University, 170 SNP Panel in total was used as the basis and its test data in the East Asian population was collected. The genetic parameters of SNP loci were calculated and combined with the results of heatmap analysis to screen SNP loci suitable for East Asian population. Some Tibetan and Han samples were tested. The possibility of using the SNP loci in ancestry inference was analyzed by means of STRUCTURE analysis, principal component analysis and heatmap analysis. Results A Panel with 45 SNPs (45 SNP Panel) was screened out, and the average genetic parameters of each SNP were better than 170 SNP Panel, with the same ancestry analysis and inference ability. Conclusion In terms of ancestry inference information, the 45 SNP Panel can completely replace the 170 SNP Panel and achieve the same ancestry analysis and inference ability. In genetic parameters, 45 SNP Panel is better than 170 SNP Panel in the East Asian population, which shows its important potential forensic application value.

Objective To explore the effect of acupuncture-rehabilitation therapy on the expression of transcription factor forkheadbox P3 (Foxp3) and retinoic acid-related orphan receptor γt (RORγt) protein in cerebral ischemic mice. Methods Forty-five female C57BL/6 mice were randomly assigned to sham operation group, model group, acupuncture group, rehabilitation group, and acupuncture-rehabilitation group, with nine mice in each group. Subsequently, each group was divided into three days, seven days and 14 days subgroups. The permanent middle cerebral artery occlusion models were established by the suture method, except the sham operation group. The sham operation group and the model group received no treatment. The acupuncture group received scalp cluster acupuncture, the rehabilitation group received treadmill training, and the acupuncture-rehabilitation group received scalp cluster acupuncture combined with treadmill training. Three days, seven days and 14 days after modeling, the modified Neurological Severity Score (mNSS) was obtained, and the expression of Foxp3 and RORγt in brain tissue of ischemic side was analyzed by Western blotting. Results The mNSS in the sham operation group was 0, and was higher in the model group than in the sham operation group at each postoperative time point. Three days after operation, the mNSS decreased in the rehabilitation group and the acupuncture-rehabilitation group, compared to the model group (P < 0.05). Fourteen days after operation, the mNSS decreased in the acupuncture-rehabilitation group, compared to the model group and acupuncture group (P < 0.05). The expression of Foxp3 protein was significantly lower in the acupuncture-rehabilitation group than in other groups at all time points after surgery( P < 0.05). Three days after operation, the expression of RORγt was higher in the acupuncture-rehabilitation group than in other groups (P < 0.05). Seven days after operation, the expression of RORγt was higher in the acupuncture-rehabilitation group than in the acupuncture group and sham operation group (P < 0.05). Conclusion Acupuncture-rehabilitation therapy may improve the tissue injury of cerebral ischemia mice, and promote the recovery of neural function, possibly by regulating Foxp3 and RORγT expression to reduce the level of inflammation, and then exert neuroprotective effects.
