Polygonati Rhizoma demonstrates significant potential for addressing both chronic and hidden hunger. The supply of high-quality seedlings is a primary factor influencing the development of the Polygonati Rhizoma industry. Warm water soaking is often used in agriculture to promote the rapid germination of seeds, while its application and molecular mechanism in Polygonati Rhizoma have not been reported. To rapidly obtain high-quality seedlings, this study treated Polygonatum kingianum var. grandifolium seeds with sand storage at low temperatures, warm water soaking, and cultivation temperature gradients. The results showed that the culture at 25 ℃ or sand storage at 4 ℃ for 2 months rapidly broke the seed dormancy of P. kingianum var. grandifolium, while the culture at 20 ℃ or sand storage at 4 ℃ for 1 month failed to break the seed dormancy. Soaking seeds in 60 ℃ warm water further increased the germination rate, germination potential, and germination index. Specifically, the seeds soaked at 60 ℃ and cultured at 25 ℃ without sand storage treatment(Aa25) achieved a germination rate of 78. 67%±1. 53% on day 42 and 83. 40%±4. 63% on day 77. The seeds pretreated with sand storage at 4 ℃ for 2 months, soaked in 60 ℃ water, and then cultured at 25 ℃ achieved a germination rate comparable to that of Aa25 on day 77. Transcriptomic analysis indicated that warm water soaking might promote germination by triggering reactive oxygen species( ROS), inducing the expression of heat shock factors( HSFs) and heat shock proteins( HSPs), which accelerated DNA replication, transcript maturation, translation, and processing, thereby facilitating the accumulation and turnover of genetic materials. According to the results of indoor controlled experiments and field practices, maintaining a germination and seedling cultivation environment at approximately 25 ℃ was crucial for the one-year seedling cultivation of P. kingianum var. grandifolium.

OBJECTIVE: To investigate lymph node metastasis (LNM) in the prostatic anterior fat pad (PAFP) of PCa patients after robot-assisted radical prostatectomy (RARP), and analyze the clinicopathological features and prognosis of LNM in the PAFP. METHODS: We retrospectively analyzed the clinicopathological data on 1 003 cases of PCa treated by RARP in the Department of Urology of PLA General Hospital from January 2017 to December 2022. All the patients underwent routine removal of the PAFP during RARP and pathological examination, with the results of all the specimens examined and reported by pathologists. Based on the presence and locations of LNM, we grouped the patients for statistical analysis, compared the clinicopathological features between different groups using the Student's t, Mann-Whitney U and Chi-square tests, and conducted survival analyses using the Kaplan-Meier and Log-rank methods and survival curves generated by Rstudio. RESULTS: Lymph nodes were detected in 77 (7.7%) of the 1 003 PAFP samples, and LNM in 11 (14.3%) of the 77 cases, with a positive rate of 1.1% (11/1 003). Of the 11 positive cases, 9 were found in the upgraded pathological N stage, and the other 2 complicated by pelvic LNM. The patients with postoperative pathological stage≥T3 constituted a significantly higher proportion in the PAFP LNM than in the non-PAFP LNM group (81.8% ［9/11］ vs 36.2% ［359/992］, P = 0.005), and so did the cases with Gleason score ≥8 (87.5% ［7/8］ vs 35.5% ［279/786］, P = 0.009). No statistically significant differences were observed in the clinicopathological features and biochemical recurrence-free survival between the patients with PAFP LNM only and those with pelvic LNM only. CONCLUSION The PAFP is a potential route to LNM, and patients with LNM in the PAFP are characterized by poor pathological features. There is no statistically significant difference in biochemical recurrence-free survival between the patients with PAFP LNM only and those with pelvic LNM only. Routine removal of the PAFP and independent pathological examination of the specimen during RARP is of great clinical significance.

OBJECTIVE: To investigate the efficacy and safety of transurethral water vapor thermal therapy (WVTT) using the Rezūm system for benign prostatic hyperplasia (BPH) in the real world. METHODS: A total of 181 patients with BPH were recruited from the Second Affiliated Hospital of Nanjing Medical University from August 2022 to December 2023, of whom 173 patients were treated with WVTT using the Rezūm system, while 8 patients were treated with WVTT combined with TURP. They were followed up at 1, 3, and 6 months postoperatively to assess changes in the IPSS, QoL, Qmax, IIEF-5, and the occurrence of any complications. Results： All 181 surgeries in this group were successfully completed. The operation time of the Rezūm system was (4.6 ± 1.4) minutes. The postoperative indwelling catheterization time was (8.0 ± 2.1) days. With a follow-up of at least 6 months, there was a significant decrease in PV, IPSS and QoL, and a remarkable increase had been found in Qmax as well (P<0.05). There was no significant difference in IIEF-5 before and after the operation (P>0.05). In this groups of patients, postoperative complications mainly included 95 cases (52.5%) of gross hematuria, 6 cases (3.3%) of retrograde ejaculation, 5 cases (2.8%) of urethral stricture, 4 cases (2.2%) of prostatitis, and 10 cases (5.5%) of urinary tract infection. Four cases (2.2%) underwent surgical retreatment for BPH after surgery. CONCLUSION In the real world, the use of Rezūm thermal steam ablation system for the treatment of BPH has satisfactory short-term effect, short surgical time, and significant improvement in IPSS, QoL, Qmax, which does not adversely affect sexual function.

Objective:To investigate the safety and therapeutic effect of split liver transplantation (SLT) in clinical application.Methods:This is a retrospective case-series study. The clinical data of 203 consecutive SLT, 79 living donor liver transplantation (LDLT) and 1 298 whole liver transplantation (WLT) performed at the Third Affiliated Hospital of Sun Yat-sen University from July 2014 to July 2023 were retrospectively analyzed. Two hundred and three SLT liver grafts were obtained from 109 donors. One hundred and twenty-seven grafts were generated by in vitro splitting and 76 grafts were generated by in vivo splitting. There were 90 adult recipients and 113 pediatric recipients. According to time, SLT patients were divided into two groups: the early SLT group (40 cases, from July 2014 to December 2017) and the mature SLT technology group (163 cases, from January 2018 to July 2023). The survival of each group was analyzed and the main factors affecting the survival rate of SLT were analyzed. The Kaplan-Meier method and Log-rank test were used for survival analysis.Results:The cumulative survival rates at 1-, 3-, and 5-year were 74.58%, 71.47%, and 71.47% in the early SLT group, and 88.03%, 87.23%, and 87.23% in the mature SLT group, respectively. Survival rates in the mature SLT group were significantly higher than those in the early SLT group ( χ2=5.560, P=0.018). The cumulative survival rates at 1-, 3- and 5-year were 93.41%, 93.41%, 89.95% in the LDLT group and 87.38%, 81.98%, 77.04% in the WLT group, respectively. There was no significant difference among the mature SLT group, the LDLT group and the WLT group ( χ2=4.016, P=0.134). Abdominal hemorrhage, infection, primary liver graft nonfunction,and portal vein thrombosis were the main causes of early postoperative death. Conclusion:SLT can achieve results comparable to those of WLT and LDLT in mature technology liver transplant centers, but it needs to go through a certain time learning curve.

Objective To analyze the influencing factors of pancreatic fat deposition in patients with type 2 diabetes mellitus(T2DM),and to explore the relationship between pancreatic fat deposition and islet function.Methods A survey on diabetes prevalence was conducted among 548 residents in the Nicheng community of Pudong New Area from October 2015 to December 2016,including 301 patients with T2DM and 247 subjects with normal glucose tolerance(NGT).General information of the subjects were recorded,blood biochemical and insulin indexes were measured,body composition was measured by dual-energy X-ray absorptiometry,and insulin resistance index(HOMA-IR)and islet cell sensitivity index(HOMA-β)were calculated.Fatty liver and pancreatic fat deposition were detected by ultrasound.Both the T2DM group and NGT group were further divided into two subgroups according to the pancreatic fat deposition.Differences in general demographic information,biochemical and body fat indices among the groups were compared.Multivariate logistic regression was used to analyze the influencing factors of pancreatic fat deposition.Results In the NGT group,the subgroup with pancreatic fat deposition showed higher levels of age,waist circumference,waist-to-hip ratio(WHR),body mass index(BMI),fasting insulin levels(FINS),2-hour postprandial insulin levels(2 h INS),triglycerides(TG),uric acid(UA),alanine aminotransferase(ALT),fatty liver prevalence,abdominal fat percentage,and abdomen-to-hip ratio(AHR),compared with the subgroup without pancreatic fat deposition.High-density lipoprotein cholesterol(HDL-C)and limb fat percentage were lower in the subgroup with pancreatic fat deposition.In the T2DM group,the subgroup with pancreatic fat deposition showed higher levels of waist circumference,BMI,FINS,2 h INS,TG,UA,ALT,aspartate aminotransferase(AST),fatty liver prevalence,and abdominal fat percentage,compared with the subgroup without pancreatic fat deposition,with statistically significant differences(P<0.05).The HOMA-IR and HOMA-β in both NGT and T2DM groups with pancreatic fat deposition were significantly higher than those in the groups without pancreatic fat deposition.The prevalence of insulin resistance also significantly increased,with statistically significant differences(P<0.05).The results of multivariate logistic regression analysis showed that HDL-C,HOMA-β,abdominal fat percentage,age and fatty liver were the influencing factors for pancreatic fat deposition in NGT.Conclusion Elderly individuals with abdominal obesity and fatty liver are more prone to developing pancreatic fat deposition,which can affect islet function and aggravate the insulin resistance.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.
