Objective:To investigate the effect of transurethral green laser prostate enucleation (GreenLEP) in the treatment of benign prostate hyperplasia (BPH) with detrusor underactivity (DU).Methods:The clinical data of 157 BPH patients treated with GreenLEP at Zhejiang Provincial People's Hospital from June 2019 to June 2020 were retrospectively analysed. The average age of the patients was (73.2±7.9) years old, with disease duration of 4(2, 8) years. Prior to surgery, all patients underwent comprehensive urodynamic studies and prostate ultrasonography (or enhanced MRI). Preoperative prostate volume was 42.1(34.2, 59.4) ml, international prostate symptom score (IPSS) was (27.9±3.4), quality of life (QOL) score was (5.1±0.8), preoperative residual urine volume (PVR) was 40.0(20.0, 80.0) ml, and preoperative maximum urinary flow rate (Q max) was 4.0(2.0, 7.0) ml/s. Patients were stratified into DU and non-DU groups using a bladder contractility index (BCI) threshold of less than 100 to diagnose DU. The cohort comprised 76 individuals in the DU group and 81 in the non-DU group. At the three-month postoperative juncture, a follow-up assessment was conducted on the patients, focusing on the evolution of subjective metrics (IPSS, QOL) and objective parameters (PVR, Q max). This study defined successful treatment outcomes at the 3-month mark as achieving PVR<20 ml and Q max>10 ml/s. Cases not meeting these criteria were categorized as treatment failure. Based on treatment outcomes, receiver operator characteristic (ROC) curve were plotted to identify the optimal cutoff value of BCI for predicting treatment efficacy. Subsequently, DU patients were classified into mild and severe DU groups based on this optimal BCI threshold. The differences of subjective indicators (IPSS, QOL) and objective parameters (PVR, Q max) preoperatively among non-DU, mild DU, and severe DU groups, as well as changes in these indices three months postoperatively were analyzed. Results:All 157 surgeries were successfully completed, with a median hospital stay of 6(5, 8) days. At the 3-month postoperative follow-up, 78 patients were deemed treatment successes and 3 as failures in non-DU group, 64 were successful and 12 failed in DU group. Utilizing ROC curve analysis, the BCI was optimally set at 57.5. This stratification resulted in 56 cases classified as mild DU (57.5≤BCI<100) group and 20 cases as severe DU (BCI<57.5) group. A comparative analysis of the three patient cohorts, revealed no significant statistical variation in terms of age, disease duration, or prostate volume ( P>0.05). In the non-DU, mild DU, and severe DU groups, IPSS were (26.8±3.4), (28.6±3.0), and (30.6±2.4) respectively, QOL sores were (4.9±0.9), (5.2±0.7), and (5.7±0.5) respectively, PVR volumes were 50.0(20.0, 90.0), 20.0(10.0, 50.0), and 60.0(27.5, 165.0) ml respectively, Q max were 4.0(2.0, 7.0), 5.0(4.0, 6.0), and 0(0, 2.3) ml/s respectively. Preoperative IPSS and QOL were significantly lower in the non-DU group compared with mild and severe DU groups ( P<0.05). Mild DU group had lower preoperative IPSS and QOL than the severe DU group ( P<0.05). Preoperative PVR in the mild DU group was less than that in both non-DU and severe DU groups ( P<0.05), but there was no statistically significant difference in preoperative PVR between non-DU and severe DU groups ( P>0.05). Preoperative Q maxof non-DU and mild DU groups was significantly higher than that of severe DU group ( P<0.05), with no significant difference between non-DU and mild DU ( P>0.05). Three months after surgery, IPSS scores of non-DU group, mild DU group and severe DU group were (12.5±4.7), (14.9±3.6) and (18.8±4.1), respectively. QOL scores of the 3 groups improved to (1.1±0.4), (1.2±0.5) and (1.9±1.0), respectively. PVR was 0 in non-DU and mild DU, and 20.0 (19.5, 61.3) ml in severe DU. Q max of the 3 groups were improved to 22.0(18.0, 27.0), 17.0(14.0, 22.3), and 9.0(6.8, 13.0) ml/s, respectively. Significant improvements of subjective symptoms (IPSS, QOL) and objective parameters (PVR, Q max) were observed in non-DU and mild DU group compared with preoperative( P<0.05). Significant improvements of IPSS, QOL and Q max ( P<0.05) but not PVR ( P=0.14)were observed in severe DU group. Additionally, significant differences were noted in PVR and Q max changes among the three groups ( P<0.05), but not in IPSS and QOL changes ( P>0.05). The absolute value of PVR and Q max changes in the non-DU group were higher than those in the mild DU group and the severe DU group ( P<0.05). Additionally, the change of Q max in mild DU group was significantly higher than that in severe DU group ( P<0.05). Conclusions:BPH patients with different degrees of DU can benefit from GreenLEP surgery, but for BPH patients with severe DU (BCI < 57.5), the improvements in PVR and Q max are less than that in the non-DU group.

Purpose The purpose of this study was to in-vestigate programmed death ligand-1(PD-L1)expression in gastric adenocarcinoma(GAC)patients and the consistency of immunohistochemical(IHC)detection of four different clones of PD-L1 antibodies,so as to provide reference for the gradual standardization of PD-L1 IHC detection in gastric adenocarcino-ma and subsequent clinical studies.Methods This study col-lected surgically resected and pathologically confirmed specimens from 286 gastric adenocarcinoma patients,and specimens were stained with four antibodies:PD-L1 22C3,SP263,E1L3N and SP142.The consistency of the antibodies was statistically ana-lyzed under different critical values using two scoring criteria:comprehensive positive score(CPS)and tumor proportion score(TPS).Results Regardless of the TPS and CPS cut-off val-ues,the positive rate of 22C3 was the highest among the four an-tibodies.Consistency analysis showed that E1L3N had good con-sistency with SP142(κ=0.612)and SP263(κ=0.660)only when the cut-off value of CPS positive was 1.In addition,the consistency between the other antibodies was only moderate or poor.Conclusion The four PD-L1 antibodies exhibited incon-sistent concordance across various TPS and CPS positive thresh-olds,so it is not recommended to exchange reagents during clini-cal testing of GAC and the test results shall be documented in accordance with the specification.

Objective:To compare the characteristics of background mucosa, lesion features, and the efficiency of endoscopic submucosal dissection(ESD)between elderly and non-elderly patients with early gastric cancer(EGC).Methods:This study retrospectively collected data on patients with EGC who underwent ESD treatment at Beijing Hospital from April 2020 to December 2022.The clinical characteristics, background mucosa, lesion features, ESD outcomes, and pathological results of the patients were analyzed to compare the differences between elderly and non-elderly patients.Results:A total of 100 patients with EGC were selected, comprising 57 patients in the elderly group and 43 patients in the non-elderly group, with a total of 111 lesions identified(64 lesions in the elderly group and 47 lesions in the non-elderly group).The proportion of patients with a history of chronic atrophic gastritis was significantly higher in the elderly group(89.5%、51/57)compared to the non-elderly group(74.4%、32/43), with a statistically significant difference( P=0.047).Additionally, the difference in the extent of atrophy between elderly patients with EGC and their non-elderly counterparts was statistically significant( P=0.022).Among these patients, the proportion of those classified as Kimura-Takemoto C0 to C1 in the elderly group(15.6%、10/64)was lower than that in the non-elderly group(40.4%、19/47).In contrast, the proportion of patients classified as C2 to C3 in the elderly group(65.6%、42/64)was higher than that in the non-elderly group(51.1%、24/47), and the proportion of those classified as O1 to O3 in elderly patients(12.5%、8/64)was also higher than in the non-elderly group(4.3%、2/47).Furthermore, the difference in the extent of intestinal metaplasia between elderly and non-elderly patients with early gastric cancer was statistically significant( P=0.007).The overall proportion of total intestinal metaplasia in elderly patients(85.9%、55/64)was significantly higher than that in non-elderly patients(61.7%、29/47).Notably, the proportion of patients exhibiting extensive intestinal metaplasia(intestinal metaplasia present in both the gastric antrum and gastric body)was greater in the elderly group(43.8%、28/64)compared to the non-elderly group(23.4%、11/47).The Kyoto gastric cancer risk endoscopic score for elderly patients with EGC was(2.43±1.28)points, significantly higher than that of the non-elderly group(1.72±1.41)points, with a statistically significant difference observed( t=2.778, P=0.006).No statistically significant differences were observed in the proportions of total resection rates, R0 resections, curative resections, or postoperative complications following ESD when comparing elderly patients with EGC to their non-elderly counterparts. Conclusions:The proportion of extensive atrophy and intestinal metaplasia was higher in the background mucosa of elderly patients with EGC, and correspondingly, the Kyoto endoscopic gastric cancer risk score was elevated.Therefore, endoscopic examinations for elderly patients with chronic atrophic gastritis should be conducted with greater care and comprehensiveness.

Glioblastoma (GBM) is the most common and aggressive malignant brain tumor in adults and is poorly controlled. Previous studies have shown that both macrophages and angiogenesis play significant roles in GBM progression, and co-targeting of CSF1R and VEGFR is likely to be an effective strategy for GBM treatment. Therefore, this study developed a novel and selective inhibitor of CSF1R and VEGFR, SYHA1813, possessing potent antitumor activity against GBM. SYHA1813 inhibited VEGFR and CSF1R kinase activities with high potency and selectivity and thus blocked the cell viability of HUVECs and macrophages and exhibited anti-angiogenetic effects both in vitro and in vivo. SYHA1813 also displayed potent in vivo antitumor activity against GBM in immune-competent and immune-deficient mouse models, including temozolomide (TMZ) insensitive tumors. Notably, SYHA1813 could penetrate the blood-brain barrier (BBB) and prolong the survival time of mice bearing intracranial GBM xenografts. Moreover, SYHA1813 treatment resulted in a synergistic antitumor efficacy in combination with the PD-1 antibody. As a clinical proof of concept, SYHA1813 achieved confirmed responses in patients with recurrent GBM in an ongoing first-in-human phase I trial. The data of this study support the rationale for an ongoing phase I clinical study (ChiCTR2100045380).

Objective:To examine the association between working hours and urinary sodium and potassium excretion levels in a population undergoing health examinations and the potential mediating effect of timely eating behaviors.Methods:In this cross-sectional study, 64 400 people who received health checkups from August 2017 to August 2022 at the Third Xiangya Hospital of Central South University were recruited as study subjects. General information on socio-demographic characteristics of the enrolled subjects were collected using the health checkup self-assessment questionnaire in the Expert Consensus on Basic Items for Health Checkups. Urinary excretion levels of sodium and potassium were measured with the Kawasaki method. The association between working hours and urinary sodium and potassium excretion levels was checked by using Pearson′s correlation analysis. The relationships between timely eating behaviors, working hours, and urinary sodium and potassium excretion levels and their ratios were analyzed using logistic regression and linear regression models, while the mediating mechanisms involved was also examined.Results:Among the 64 400 subjects, there were 39 274 males (60.98%) and 25 126 females (39.02%), the mean age was (43.80±11.13) years. There were 16 980 individuals (26.37%) with an average working time exceeding 8 hours per day. Additionally, 4 332 subjects (6.73%) were unable to eat three meals on time. The mean urinary sodium and potassium excretion and their ratios were (4.12±1.86) g/d, (2.06±0.80) g/d, 2.05±0.66, respectively. There was a significant positive correlation between working hours and urinary sodium excretion, urinary potassium excretion, and their ratios ( r=0.034, 0.021, 0.032, respectivley); it showed that timely eating behavior had a significant negative correlation with urinary sodium and potassium excretion ( r=-0.022, -0.019, respectivley) (all P<0.001). There was a partial mediating effect of timely eating behavior in the association between working hours and urinary sodium excretion (effect value of -0.006), and after stratifying the labor intensity, this mediating effect was only found among individuals engaged in light physical labor (both P<0.001). Conclusions:Prolonged working hours leads to increased levels of urinary sodium and urinary potassium excretion, and timely eating behavior facilitates salt/sodium reduction in light-duty workers.

Background: The risk factors affecting the non ⁃ curative resection of endoscopic submucosal dissection (ESD) for early colorectal cancer and precancerous lesions were still lacking large scale studies in China. Aims: To analyze the efficacy of ESD for patients with early colorectal cancer and precancerous lesions, and explore the risk factors affecting the non⁃curative resection. Methods: A total of 229 patients with early colorectal cancer and precancerous lesions underwent ESD from September 2016 to September 2021 at Beijing Hospital were collected. The clinicopathological characteristics, efficacy of ESD were analyzed. Risk factors affecting the non ⁃ curative resection of ESD were analyzed by univariate analysis and Logistic multivariate regression analysis. Results: A total of 255 lesions were found. The en bloc resection rate was 90.2%, R0 resection rate was 87.8%, and curative resection rate was 83.5%. The total incidence of complications was 2.7%. Univariate analysis showed that detection rate of intraluminal protruding tumor (61.0% vs. 24.4%, P<0.05), rate of severe submucosal fibrosis (24.4% vs. 2.4%, P<0.05) were significantly increased in the non⁃curative resection group than in the curative resection group, and positive rate of lifting sign was significantly decreased (80.5% vs. 95.1%, P<0.05). Logistic multivariate regression analysis showed that intraluminal protruding tumor (OR=4.087, 95% CI: 1.523⁃10.968, P= 0.005) and severe submucosal fibrosis (OR=9.609, 95% CI: 1.107⁃83.439, P=0.04) were risk factors for ESD non⁃curative resection of early colorectal cancer and precancerous lesions. Conclusions: R0 resection rate and curative resection rate of ESD for early colorectal cancer and precancerous lesions are high, the incidence of surgical complications is low. Intraluminal protruding tumor, severe submucosal fibrosis are the independent risk factors of non⁃curative resection. Strict evaluation should be carried out before operation and reasonable treatment strategies should be formulated accordingly.

OBJECTIVES: The plateau environment is characterized by low oxygen partial pressure, leading to the reduction of oxygen carrying capacity in alveoli and the reduction of available oxygen in tissues, and thus causing tissue damage. Cilostazol is a phosphodiesterase III inhibitor that has been reported to increase the oxygen release of hemoglobin (Hb) in tissues. This study aims to explore the anti-hypoxic activity of cilostazol and its anti-hypoxic effect. METHODS: A total of 40 male BALB/C mice were randomly divided into a low-dose cilostazol (6.5 mg/kg) group, a medium-dose (13 mg/kg) group, a high-dose (26 mg/kg) group, and a control group. The atmospheric airtight hypoxia experiment was used to investigate the anti-hypoxic activity of cilostazol and to screen the optimal dosage. Twenty-four male Wistar rats were randomly divided into a normoxia control group, a hypoxia model group, an acetazolamide (22.33 mg/kg) group, and a cilostazol (9 mg/kg) group. After 3 days of hypoxia in the 4 010 m high altitude, blood from the abdominal aorta was collected to determine blood gas indicators, the levels of IL-6 and TNF-α in plasma were determined by enzyme-linked immunosorbent assay, and the levels of malondialdehyde (MDA), superoxide dismutase (SOD), and glutataione (GSH) were measured. The degree of pathological damage for rat tissues was observed with HE staining. RESULTS: Compared with the control group, the survival time of mice in the low, medium, and high dose group of cilostazol was significantly prolonged, and the survival time of mice in the medium dose group was the longest, with an extension rate at 29.34%, so the medium dose was the best dose. Compared with the hypoxia model group, the P50 (oxygen partial pressure at Hb oxygen saturation of 50%) value of rats in the cilostazol group was significantly increased by 1.03%; Hb and Hct were significantly reduced by 8.46% and 8.43%, and the levels of IL-6 and TNF-α in plasma were reduced by 50.65% and 30.77%. The MDA contents in heart, brain, lung, liver, and kidney tissues were reduced by 37.12%, 29.55%, 25.00%, 39.34%, and 21.47%, respectively. The SOD activities were increased by 94.93%, 9.14%, 9.42%, 13.29%, and 20.80%, respectively. The GSH contents were increased by 95.24%, 28.62%, 28.57%, 20.80%, and 44.00%, respectively. The results of HE staining showed that compared with the hypoxia model group, cilostazol significantly improved the damage of heart, lung, and kidney tissues in rats after hypoxia. CONCLUSIONS Cilostazol can significantly improve the oxidative stress and inflammatory reaction caused by rapid altitude hypoxia, and it has a significant protective effect on tissue damage caused by hypoxia, suggesting that it has obvious anti-hypoxic activity.

The clinicopathological data of 242 gastric cancer patients who underwent laparoscopic radical gastrectomy in 19 hospitals of the Chinese Laparoscopic Gastrointestinal Surgery Study Group-04 study, including 54 patients in Fujian Medical University Union Hospital, 32 patients in the First Hospital of Putian City, 32 patients in Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine, 31 patients in Zhangzhou Affiliated Hospital of Fujian Medical University, 17 patients in Nanfang Hospital of Southern Medical University, 11 patients in the First Affiliated Hospital with Nanjing Medical University, 8 patients in Qinghai University Affiliated Hospital, 8 patients in Meizhou People′s Hospital, 7 patients in Fujian Provincial Hospital, 6 patients in Zhongshan Hospital of Fudan University, 6 patients in Longyan First Hospital, 5 patients in the First Affiliated Hospital of Xinjiang Medical University, 5 patients in the First Hospital Affiliated to Army Medical University, 4 patients in the Second Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine, 4 patients in West China Hospital of Sichuan University, 4 patients in Beijing University Cancer Hospital, 3 patients in the First Affiliated Hospital of Xiamen University, 3 patients in Guangdong Provincial People′s Hospital, 2 patients in the First Affiliated Hospital of Xi′an Jiaotong University, from September 2016 to October 2017 were collected. There were 193 males and 49 females, aged 62(range, 23?74)years. Observation indicators: (1) age distribution, comorbidities and ACCI status of patients; (2) the grouping of ACCI and comparison of clinicopathological characteristics of patients in each group; (3) incidence of postoperative early complications and analysis of factors affecting postoperative early complications; (4) follow-up; (5) analysis of factors affecting the 3-year recurrence-free survival rate of patients. Follow-up was conducted using outpatient examination or telephone interview to detect postoperative survival of patients up to December 2020. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the nonparametric rank sum test. The X-Tile software (version 3.6.1) was used to analyze the best ACCI grouping threshold. The Kaplan-Meier method was used to calculate survival rates and draw survival curves. The Log-Rank test was used for survival analysis. The Logistic regression model was used to analyze the factors affecting postoperative early complications. The COX proportional hazard model was used for univariate and multivariate analyses of factors affecting the 3-year recurrence-free survival rate of patients. Multivariate analysis used stepwise regression to include variables with P<0.05 in univariate analysis and variables clinically closely related to prognosis. Results:(1) Age distribution, comor-bidities and ACCI status of patients. Of the 242 patients, there were 28 cases with age <50 years, 68 cases with age of 50 to 59 years, 113 cases with age of 60 to 69 years, 33 cases with age of 70 to 79 years. There was 1 patient combined with mild liver disease, 1 patient combined with diabetes of end-organ damage, 2 patients combined with peripheral vascular diseases, 2 patients combined with peptic ulcer, 6 patients combined with congestive heart failure, 8 patients combined with chronic pulmonary diseases, 9 patients with diabetes without end-organ damage. The ACCI of 242 patients was 2 (range, 0-4). (2) The grouping of ACCI and comparison of clinicopathological characteristics of patients in each group. Results of X-Tile software analysis showed that ACCI=3 was the best grouping threshold. Of the 242 patients, 194 cases with ACCI <3 were set as the low ACCI group and 48 cases with ACCI ≥3 were set as the high ACCI group, respectively. Age, body mass index, cases with preoperative comorbidities, cases of American Society of Anesthesiologists classification as stage Ⅰ, stage Ⅱ, stage Ⅲ, tumor diameter, cases with tumor histological type as signet ring cell or poorly differentiated adenocarcinoma and cases with tumor type as moderately or well differentiated adenocarcinoma, cases with tumor pathological T staging as stage T1, stage T2, stage T3, stage T4, chemotherapy cycles were (58±9)years, (22.6±2.9)kg/m 2, 31, 106, 85, 3, (4.0±1.9)cm, 104, 90, 16, 29, 72, 77, 6(4,6) in the low ACCI group, versus (70±4) years, (21.7±2.7)kg/m 2, 23, 14, 33, 1, (5.4±3.1)cm, 36, 12, 3, 4, 13, 28, 4(2,5) in the high ACCI group, showing significant differences in the above indicators between the two groups ( t=-14.37, 1.98, χ2=22.64, Z=-3.11, t=-2.91, χ2=7.22, Z=-2.21, -3.61, P<0.05). (3) Incidence of postoperative early complications and analysis of factors affecting postoperative early complications. Of the 242 patients, 33 cases had postoperative early complications, including 20 cases with local complications and 16 cases with systemic complica-tions. Some patients had multiple complications at the same time. Of the 20 patients with local complications, 12 cases had abdominal infection, 7 cases had anastomotic leakage, 2 cases had incision infection, 2 cases had abdominal hemorrhage, 2 cases had anastomotic hemorrhage and 1 case had lymphatic leakage. Of the 16 patients with systemic complications, 11 cases had pulmonary infection, 2 cases had arrhythmias, 2 cases had sepsis, 1 case had liver failure, 1 case had renal failure, 1 case had pulmonary embolism, 1 case had deep vein thrombosis, 1 case had urinary infection and 1 case had urine retention. Of the 33 cases with postoperative early complications, there were 3 cases with grade Ⅰ complications, 22 cases with grade Ⅱ complications, 5 cases with grade Ⅲa complications, 2 cases with grade Ⅲb complications and 1 case with grade Ⅳ complica-tions of Clavien-Dindo classification. Cases with postoperative early complications, cases with local complications, cases with systemic complications were 22, 13, 9 in the low ACCI group, versus 11, 7, 7 in the high ACCI group, respectively. There were significant differences in cases with postoperative early complications and cases with systemic complications between the two groups ( χ2=4.38, 4.66, P<0.05), and there was no significant difference in cases with local complications between the two groups ( χ2=2.20, P>0.05). Results of Logistic regression analysis showed that ACCI was a related factor for postoperative early complications of gastric cancer patients undergoing laparoscopic radical gastrectomy [ odds ratio=2.32, 95% confidence interval ( CI) as 1.04-5.21, P<0.05]. (4) Follow-up. All the 242 patients were followed up for 36(range,1?46)months. During the follow-up, 53 patients died and 13 patients survived with tumor. The 3-year recurrence-free survival rate of the 242 patients was 73.5%. The follow-up time, cases died and cases survived with tumor during follow-up, the 3-year recurrence-free survival rate were 36(range, 2-46)months, 29, 10, 80.0% for the low ACCI group, versus 35(range, 1-42)months, 24, 3, 47.4% for the high ACCI group. There was a significant difference in the 3-year recurrence-free survival rate between the two groups ( χ2=30.49, P<0.05). (5) Analysis of factors affecting the 3-year recurrence-free survival rate of patients. Results of univariate analysis showed that preoperative comorbidities, ACCI, tumor diameter, histological type, vascular invasion, lymphatic invasion, neural invasion, tumor pathological TNM staging, postoperative early complications were related factors for postoperative 3-year recurrence-free survival rate of gastric cancer patients undergoing laparoscopic radical gastrectomy [ hazard ratio ( HR)=2.52, 3.64, 2.62, 0.47, 2.87, 1.90, 1.86, 21.77, 1.97, 95% CI as 1.52-4.17, 2.22-5.95, 1.54-4.46, 0.27-0.80, 1.76-4.70, 1.15-3.12, 1.10-3.14, 3.01-157.52, 1.11-3.50, P<0.05]. Results of multivariate analysis showed that ACCI, tumor pathological TNM staging, adjuvant chemotherapy were indepen-dent influencing factors for postoperative 3-year recurrence-free survival rate of gastric cancer patients undergoing laparoscopic radical gastrectomy ( HR=3.65, 11.00, 40.66, 0.39, 95% CI as 2.21-6.02, 1.40-86.73, 5.41-305.69, 0.22-0.68, P<0.05). Conclusions:ACCI is a related factor for post-operative early complications of gastric cancer patients undergoing laparos-copic radical gastrectomy. ACCI, tumor pathological TNM staging, adjuvant chemotherapy are indepen-dent influencing factors for postoperative 3-year recurrence-free survival rate of gastric cancer patients undergoing laparoscopic radical gastrectomy.
