Objective:To investigate the effect of uridine diphosphate ceramide galactosyltransferase 8(UGT8)on colorectal cancer(CRC)cell growth and migration,elucidate an underlying mechanism,and assess the potential regulatory role of SRY-box transcription factor 9(SOX9)on UGT8.Methods:UGT8 and SOX9 mRNA expression levels in CRC tissues,and correlation between their expression levels,were analyzed using GEPIA2,UALCAN,and TIMER 2.0 online databases.UGT8 and SOX9 protein expression in CRC and adjacent tissues was detec-ted using immunohistochemistry,and relationships between their expression and clinicopathological characteristics were analyzed.Impact of UGT8 knockdown on CRC cell proliferation was assessed using a CCK-8 assay,and cell migration was evaluated using Transwell and wound healing assays.Western blot was performed to detect expression of epithelial-mesenchymal transition(EMT)markers(E-cadherin and ZEB1).RT-qPCR and Western blot were used to measure UGT8 mRNA and protein expression levels after SOX9 knockdown.The JASPAR online database was used to assess SOX9 potential for binding to the UGT8 promoter.Results:Bioinformatics analyses revealed significantly higher mRNA expression levels of both UGT8 and SOX9 in CRC tissues than in normal tissues.Positive correlation was observed between expres-sion levels.Immunohistochemistry results showed that tumor UGT8 and SOX9 protein levels were significantly higher than those in adjacent tissues.UGT8 protein level was found to correlates with N stage,and SOX9 protein level correlated with T stage.A positive correlation was observed between UGT8 and SOX9 expression levels.Following UGT8 knockdown,cell proliferation capacity was attenuated and cell migra-tion ability was reduced.E-cadherin expression concurrently increased and ZEB1 expression decreased.RT-qPCR and Western blot results showed that SOX9 knockdown significantly reduced UGT8 mRNA and protein levels.The JASPER website predicts that SOX9 will bind to the UGT8 promoter.Conclusions:UGT8 and SOX9 are highly expressed in CRC tissues,and their expression levels correlate with clinicopatholo-gical features.UGT8 and SOX9 expression levels display significant positive correlation.Mechanistically,UGT8 promotes CRC cell prolifera-tion and migration by facilitating epithelial-mesenchymal transition(EMT).SOX9 enhances UGT8 mRNA and protein expression and may bind to the UGT8 promoter region.

Objective:To compare the safety, number of lymph nodes removed, rate of lymph node metastasis, and prognosis between proximal gastrectomy (PG) and total gastrectomy (TG) in patients with Siewert types II and III adenocarcinoma of the esophagogastric junction.Methods:In this retrospective cohort study, clinical data of patients diagnosed with adenocarcinoma of the esophagogastric junction at Changzhi People's Hospital, affiliated with Changzhi Medical College, between December 2019 and November 2022, were collected. Patients who had received neoadjuvant therapy, had multiple malignant lesions in the stomach, had concomitant malignancies in other organs, had incomplete clinical data, or had been lost to follow-up were excluded. The study cohort comprised 308 patients, 99 in the PG group and 209 in the TG group. To reduce confounding bias, propensity score matching was performed, matching patients for age, sex, body mass index, tumor diameter, and pathological stage in a 1:1 ratio, resulting in 73 patients in each group. The primary outcomes assessed were operative details, number of lymph nodes dissected, rate of lymph node metastasis, postoperative complications, duration of hospital stay, and follow-up and survival outcomes.Results:The PG group had a significantly shorter median operative time than did the TG group (250 vs. 280 minutes, Z = -4.970, P<0.001), with fewer cases of intraoperative blood loss >100 mL (30.1%[22/73] vs. 46.6%[34/73], χ2=4.171, P=0.041), and a smaller number of lymph nodes removed (median 33 vs. 46, Z =-4.774, P<0.001); all of these differences are statistically significant (all P<0.05). Differences between the two groups in postoperative hospital stay and postoperative complications were not statistically significant (both P>0.05). Furthermore, no statistically significant differences were found between the PG and TG groups in the number of lymph nodes dissected or the lymph node metastasis rates at stations No. 1, No. 2, No. 3, No. 4sa, No. 4sb, and No. 7 (all P> 0.05). Among the 209 patients in the TG group, analysis of risk factors for metastasis to distal perigastric lymph nodes (No.4d, No.5, and No.6) showed that patients with tumor diameters ≤4 cm and T1–T3 stage disease had significantly lower rates of metastasis to these lymph nodes than did patients with tumor diameters >4 cm and/or T4 stage disease (0/78 vs. 12/131 [9.2%]); these differences are statistically significant ( P=0.014). The median duration of follow-up for the entire cohort was 26 months. The 3-year overall survival rates for the PG and TG groups were 62.5% and 63.3%, respectively; this difference is not statistically significant (χ 2=0.330, P = 0.565). Multivariate analysis showed that older age ( P = 0.035) and advanced pathological stage ( P = 0.018) were significant independent risk factors that affected overall survival in patients with Siewert type II and III adenocarcinoma of the esophagogastric junction. Conclusions:PG is safe and feasible for patients with Siewert types II and III adenocarcinoma of the esophagogastric junction. The number of lymph nodes dissected and metastasis status were similar in the TG and PG groups.

In this study, we proposed an idea on systematic construction and optimization of a clinical coaching teacher qualification access system in Peking University Third Hospital by combining lean thinking and the Six Sigma methodology and following the steps of definition, measurement, analysis, improvement, and control. Based on the constructivism theory, the clinical coaching teacher qualification access system is divided into two progressive sessions: access to clinical coaching qualifications and access to theoretical teaching qualifications. By analyzing the appraisal data of clinical coaching teacher qualification access in the past 10 years, we revealed the data characteristics of pass rates of clinical coaching qualifications to determine the goal for dynamic improvement. On top of this analysis, we identified measures to maintain a stable pass rate of clinical coaching teacher qualification access, optimized the development direction and path of the clinical coaching teacher qualification access, and continuously promoted the teaching ability of teachers through the coordinated implementation of different systems and measures. In our research, we expanded the administrative scope of the access system, sorted out the objectives and paths of the system improvement, and provided a practical reference for constructing a clinical coaching teacher qualification access system and promoting the construction of teaching quality standardization in university-affiliated hospitals.

Objective:To investigate the application value of optimized mesenteric defect closure technique in laparoscopic-assisted right hemicolectomy.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 26 patients who underwent laparo-scopic-assisted right hemicolectomy at Changzhi People′s Hospital Affiliated to Changzhi Medical College from May 2023 to June 2024 were collected. There were 11 males and 15 females, aged (65.7±1.8)years. All patients received optimized mesenteric defect closure using a combined extra-corporeal-laparoscopic suturing technique. Observation indicators: (1) surgical and intraoperative conditions; (2) postoperative conditions; (3) follow-up. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M( Q1, Q3) or M(range). Count data were described as absolute numbers. Results:(1) Surgical and intraoperative conditions. All 26 patients underwent laparoscopic-assisted right hemicolectomy with optimized mesenteric defect closure. The time of optimized mesenteric defect closure was 9.8(8.8,12.8)minutes, time of digestive tract reconstruction was 10.0(8.7,13.0)minutes, operation time was (164±4)minutes, volume of intraoperative blood loss was 50(50,100)mL. One of the 26 patients had intraoperative mesenteric hematoma, which required no specific intervention. The patient recovered uneventfully and was discharged from hospital. (2) Postoperative conditions. The visual analog scale pain score of 26 patients on postoperative day 1 and day 3 were 5(4,5) and 3(2,3), respectively. Time to postoperative first anal flatus and bowel movement were both 3(3, 4)days. Time to postoperative first intake of liquid diet was 2(2,3)days, duration of postoperative abdominal drainage was 4(3,5)days, and duration of postoperative hospital stay was 9(8,12)days. The number of lymph node dissected in 26 patients was 25(18,27) and the number of positive lymph node was 1(0,2). Cases in stage Ⅰ, stage Ⅱ and stage Ⅲ of tumor TNM staging were 5, 6, 15. (3) Follow-up. All 26 patients were followed up for 15(range, 6?20)months. Of the 26 patients, one case had incom-plete intestinal obstruction on postoperative day 25, which was diagnosed as adhesive intestinal obstruction based on imaging examination and classified as Clavien-Dindo grade Ⅱ. The patient recovered and was discharged after conservative treatment. None of the 26 patients had bleeding, infection of incision, anastomotic leakage, internal hernia, or delayed gastric emptying. There was no tumor recurrence, metastasis or death.Conclusion:The optimized mesenteric defect closure tech-nique in combined extracorporeal-laparoscopic suturing procedure can be used in laparoscopic-assisted right hemicolectomy.
