Objective To compare of the efficacy of two distinct debridement techniques in membrane induction therapy for chronic tibial osteomyelitis.Methods A retrospective study was conducted on 52 patients with Cierny-Mader type IV A/B chronic tibial osteomyelitis who were treated at the Third Affiliated Hospital of Zunyi Medical University between July 2016 and December 2023.Five patients were diagnosed and treated before 2020,while 47 were managed from 2020 onward.Patients were divided into two groups:a local debridement group(n=28)and an en bloc osteotomy group(n=24).Perioperative outcomes—including operative time,incision length,intraoperative blood loss,and length of hospital stay—were assessed,along with clinical efficacy at 6 months,12 months,and final follow-up.Clinical outcomes were evaluated using the Hospital for Special Surgery(HSS)knee score,the American Orthopaedic Foot&Ankle Society(AOFAS)ankle-hindfoot score,joint range of motion(knee flexion-extension and ankle plantarflexion-dorsiflexion),recurrence rate,and the Paley classification for infectious bone defects.Results The local debridement group exhibited significantly less intraoperative blood loss(P<0.05),shorter operative time(P<0.05),and reduced hospital stay(P<0.05),as well as higher AOFAS and HSS scores at both 6 and 12 months postoperatively(P<0.05).In contrast,the osteotomy group demonstrated superior Paley classification outcomes at 6 months,12 months,and final follow-up(P<0.05),along with lower rates of infection recurrence.Longitudinal analysis indicated significant improvements in AOFAS scores,HSS scores,and joint mobility over time in both groups(P<0.05).However,no statistically significant differences were observed between groups in terms of functional scores or joint mobility parameters at final follow-up(P>0.05).Conclusion En bloc osteotomy combined with the induced membrane technique(Masquelet technique)enables more comprehensive debridement,minimizes the necessity for repeated surgical interventions,reduces postoperative complications,lowers the risk of recurrence,and promotes enhanced bone healing.

OBJECTIVE: To explore and verify the effect and potential mechanism of Brucea javanica Seed Oil Emulsion Injection (YDZI) and Shengmai Injection (SMI) on peripheral microcirculation dysfunction in treatment of gastric cancer (GC). METHODS: The potential mechanisms of YDZI and SMI were explored through network pharmacology and verified by cellular and clinical experiments. Human microvascular endothelial cells (HMECs) were cultured for quantitative real-time polymerase chain reaction, Western blot analysis, and human umbilical vein endothelial cells (HUVECs) were cultured for tube formation assay. Twenty healthy volunteers and 97 patients with GC were enrolled. Patients were divided into surgical resection, surgical resection with chemotherapy, and surgical resection with chemotherapy combining YDZI and SMI groups. Forearm skin blood perfusion was measured and recorded by laser speckle contrast imaging coupled with post-occlusive reactive hyperemia. Cutaneous vascular conductance and microvascular reactivity parameters were calculated and compared across the groups. RESULTS: After network pharmacology analysis, 4 ingredients, 82 active compounds, and 92 related genes in YDZI and SMI were screened out. β-Sitosterol, an active ingredient and intersection compound of YDZI and SMI, upregulated the expression of vascular endothelial growth factor A (VEGFA) and prostaglandin-endoperoxide synthase 2 (PTGS2, P<0.01), downregulated the expression of caspase 9 (CASP9) and estrogen receptor 1 (ESR1, P<0.01) in HMECs under oxaliplatin stimulation, and promoted tube formation through VEGFA. Chemotherapy significantly impaired the microvascular reactivity in GC patients, whereas YDZI and SMI ameliorated this injury (P<0.05 or P<0.01). CONCLUSIONS YDZI and SMI ameliorated peripheral microvascular reactivity in GC patients. β-Sitosterol may improve peripheral microcirculation by regulating VEGFA, PTGS2, ESR1, and CASP9.

Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

Objective To explore the effect of residual tissue glue in forceps channels on the disinfection quality of digestive endoscopes. Methods A total of 103 forceps channels of digestive endoscopes in the Digestive Endoscopy Center of the hospital from March 2022 to June 2023 were randomly selected, and the residual situation of tissue glue in the forceps channels of the endoscopes was observed after cleaning and disinfection. The endoscopes were divided into residual group and non-residual group based on the residual situation of tissue glue in the forceps channels, the disinfection quality and microbial conditions of digestive endoscopes in both groups were detected, and the factors affecting the disinfection quality of digestive endoscopes were analyzed. Results Among the 103 forceps channels, 70 channels (67.96%) had residual tissue glue; the disinfection qualification rate and bacteriological qualification rate of the non-residual group were significantly higher than those of the residual group (P<0.05). There were four personnel carrying out disinfection, and the proportion of qualified disinfection water quality was higher than that of poor group (P<0.05). Conclusion The higher the residual rate of tissue glue in forceps channels and the bacterial detection rate are, and the lower the disinfection quality of digestive endoscopes is. The quality of disinfection water and the number of disinfection personnel can affect the disinfection quality of digestive endoscopes.

Objective:To explore the clinical efficacy of DELTA endoscopic lumbar interbody fusion for the treatment of mild to moderate, single segment lumbar spondylolisthesis.Methods:A retrospective analysis was conducted on the clinical data of 48 surgical cases of grade Ⅰ to Ⅱ lumbar spondylolisthesis admitted to the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine from February 2020 to March 2022. Among them, 24 cases treated with DELTA endoscopic lumbar interbody fusion surgery were classified as the DELTA group, and 24 cases treated with traditional minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) surgery were classified as the MIS-TLIF group. Two groups of patients were compared in terms of perioperative indicators (surgical time, postoperative drainage volume, incision length, hospital stay), clinical efficacy [Visual Analogue Scale (VAS) score for low back and leg pain, lumbar Japanese Orthopaedic Association Scores (JOA), improved MacNab standard excellence rate], and lumbar fusion rate (Bridwell intervertebral fusion grade).Results:The DELTA group had longer surgical time than the MIS-TLIF group, and the postoperative drainage volume, incision length, and hospital stay were all lower than the MIS-TLIF group, with statistically significant differences (all P<0.05). The VAS score of lower back and leg pain and lumbar JOA score of the two groups of patients at 1 week, 3 months, and the last follow-up were significantly improved compared to those before surgery (all P<0.01), and the DELTA group had better VAS score of lower back and leg pain and lumbar JOA score at all time points after surgery than the MIS-TLIF group, with statistically significant differences (all P<0.05). The improved MacNab standard was used to evaluate the efficacy of the two groups of patients at the last follow-up after surgery, and there was no statistically significant difference in the excellent and good rates ( P>0.05); There was no statistically significant difference ( P>0.05) in the fusion rate between the two groups. Conclusions:DELTA endoscopic lumbar interbody fusion has a significant therapeutic effect on lumbar spondylolisthesis, with the advantages of small surgical incision and fast recovery; After crossing the DELTA endoscopic learning curve and optimizing surgical procedures, this technology can become an alternative to MIS-TLIF technology.

OBJECTIVE: AP2/ERF (APETALA2/ethylene-responsive factor) superfamily is one of the largest gene families in plants and has been reported to participate in various biological processes, such as the regulation of biosynthesis of active lignan. However, few studies have investigated the genome-wide role of the AP2/ERF superfamily in Isatis indigotica. This study establishes a complete picture of the AP2/ERF superfamily in I. indigotica and contributes valuable information for further functional characterization of IiAP2/ERF genes and supports further metabolic engineering. METHODS: To identify the IiAP2/ERF superfamily genes, the AP2/ERF sequences from Arabidopsis thaliana and Brassica rapa were used as query sequences in the basic local alignment search tool. Bioinformatic analyses were conducted to investigate the protein structure, motif composition, chromosome location, phylogenetic relationship, and interaction network of the IiAP2/ERF superfamily genes. The accuracy of omics data was verified by quantitative polymerase chain reaction and heatmap analyses. RESULTS: One hundred and twenty-six putative IiAP2/ERF genes in total were identified from the I. indigotica genome database in this study. By sequence alignment and phylogenetic analysis, the IiAP2/ERF genes were classified into 5 groups including AP2, ERF, DREB (dehydration-responsive element-binding factor), Soloist and RAV (related to abscisic acid insensitive 3/viviparous 1) subfamilies. Among which, 122 members were unevenly distributed across seven chromosomes. Sequence alignment showed that I. indigotica and A. thaliana had 30 pairs of orthologous genes, and we constructed their interaction network. The comprehensive analysis of gene expression pattern in different tissues suggested that these genes may play a significant role in organ growth and development of I. indigotica. Members that may regulate lignan biosynthesis in roots were also preliminarily identified. Ribonucleic acid sequencing analysis revealed that the expression of 76 IiAP2/ERF genes were up- or down-regulated under salt or drought treatment, among which, 33 IiAP2/ERF genes were regulated by both stresses. CONCLUSION This study undertook a genome-wide characterization of the AP2/ERF superfamily in I. indigotica, providing valuable information for further functional characterization of IiAP2/ERF genes and discovery of genetic targets for metabolic engineering.
