OBJECTIVE: To evaluate the impact of sutureless approach to the dorsal venous complex (DVC) combined with robotic-assisted laparoscopic prostatectomy on sexual function of patients with prostatic cancer. METHODS: This study included 114 prostate cancer patients who underwent robot-assisted laparoscopic radical prostatectomy at our hospital from January 2021 to January 2024. The patients were randomly divided into a control group (n=57) and an observation group (n=57). The control group received conventional "figure-of-eight" suture ligation of the dorsal venous complex (DVC), while the observation group underwent direct DVC transection using monopolar electrocautery scissors after increasing pneumoperitoneum pressure.Surgical duration, intraoperative blood loss, positive surgical margin rates, and positive apical margin rates were recorded. The continence rates and rates of morning erections at 1, 3 and 6 months after the operation were compared between groups. Sexual function was assessed pre-operatively and at 6 months post-operation by using the IIEF-5 and PEDT. RESULTS: The operative time in the observation group was significantly longer than that in the control group (［115.71 ± 19.42］ min vs ［103.42 ± 12.78］ min， P<0.05). While no significant differences were observed in intraoperative blood loss, positive surgical margin rate, or positive apical margin rate between the two groups (P>0.05). At 3 and 6 months after the operation, the observation group exhibited higher urinary continence rates and morning erection recovery rates compared to the control group （P<0.05). Furthermore, at 6 months postoperatively, the observation group demonstrated significantly higher IIEF-5 scores and lower PEDT scores than those of control group(P<0.05). CONCLUSION The use of a sutureless DVC technique in robotic-assisted laparoscopic radical prostatectomy protects the post-operative sexual function in patients.

Objective To explore the efficacy of T-cell spot test of tuberculosis infection(T-SPOT.TB)in the differential diagnosis of spinal tuberculosis(STB),and optimize diagnostic efficacy through the optimal cut-off value of receiver operating characteristic(ROC)curve.Methods Clinical data of patients with spinal infection in a hospi-tal from January 2010 to May 2019 were collected,including preoperative T-SPOT.TB test results,white blood cell count,C-reactive protein,erythrocyte sedimentation rate,procalcitonin,and tuberculosis antibodies,etal.Clinical diagnosis was conducted based on diagnostic criteria.The sensitivity and specificity of T-SPOT.TB in preoperative diagnosis of STB and other spinal infection was analyzed,and the diagnostic efficacy of the optimized T-SPOT.TB indicators was evaluated.Results A total of 132 patients were included in this study,out of whom 78 patients(59.09％)were diagnosed with STB,and 54(40.91％)were diagnosed with non-tuberculosis(non-TB)spinal in-fection.The sensitivity and specificity of T-SPOT.TB in differential diagnosis of STB were 67.68％and 66.67％,respectively.Univariate logistic regression analysis showed that compared with non-TB spinal infection,the OR va-lue of T-SPOT.TB test in diagnosing STB was 4.188(95％CI:1.847-9.974,P＜0.001).The optimized T-SPOT.TB evaluation index through ROC curve to determine the optimal cut-off values of ESAT-6,CFP-10,and CFP-10+ESAT-6 for differential diagnosis of STB and non-TB spinal infection were 12.5,19.5,and 36,respec-tively,and area under curve(AUC)values were 0.765 6,0.741 5,and 0.778 6,respectively,all with good diag-nostic efficacy.CFP-10+ESAT-6 had the highest AUC.CFP-10+ESAT-6 specific spot count had higher efficacy in the diagnosis of STB,with a diagnostic accuracy of 75.56％,higher than 67.42％of pre-optimized T-SPOT.TB.Conclusion T-SPOT.TB test has high diagnostic efficacy in differentiating STB from non-TB spinal infection.Posi-tivity in T-SPOT.TB test,especially with spot count of CFP-10+ESAT-6 over 36,indicates a higher likelihood of STB.

Objective:To investigate the current status of endoscopic treatment for gastroesophageal varices in portal hypertension in China, and to provide supporting data and reference for the development of endoscopic treatment.Methods:In this study, initiated by the Liver Health Consortium in China (CHESS), a questionnaire was designed and distributed online to investigate the basic condition of endoscopic treatment for gastroesophageal varices in portal hypertension in 2022 in China. Questions included annual number and indication of endoscopic procedures, adherence to guideline for preventing esophagogastric variceal bleeding (EGVB), management and timing of emergent EGVB, management of gastric and isolated varices, and improvement of endoscopic treatment. Proportions of hospitals concerning therapeutic choices to all participant hospitals were calculated. Guideline adherence between secondary and tertiary hospitals were compared by using Chi-square test.Results:A total of 836 hospitals from 31 provinces (anotomous regions and municipalities) participated in the survey. According to the survey, the control of acute EGVB (49.3%, 412/836) and the prevention of recurrent bleeding (38.3%, 320/836) were major indications of endoscopic treatment. For primary [non-selective β-blocker (NSBB) or endoscopic therapies] and secondary prophylaxis (NSBB and endoscopic therapies) of EGVB, adherence to domestic guideline was 72.5% (606/836) and 39.2% (328/836), respectively. There were significant differences in the adherence between secondary and tertiary hospitals in primary prophylaxis of EGVB [71.0% (495/697) VS 79.9% (111/139), χ2=4.11, P=0.033] and secondary prophylaxis of EGVB [41.6% (290/697) VS 27.3% (38/139), χ2=9.31, P=0.002]. A total of 78.2% (654/836) hospitals preferred endoscopic therapies treating acute EGVB, and endoscopic therapy was more likely to be the first choice for treating acute EGVB in tertiary hospitals (82.6%, 576/697) than secondary hospitals [56.1% (78/139), χ2=46.33, P<0.001]. The optimal timing was usually within 12 hours (48.5%, 317/654) and 12-24 hours (36.9%, 241/654) after the bleeding. Regarding the management of gastroesophageal varices type 2 and isolated gastric varices type 1, most hospitals used cyanoacrylate injection in combination with sclerotherapy [48.2% (403/836) and 29.9% (250/836), respectively], but substantial proportions of hospitals preferred clip-assisted therapies [12.4% (104/836) and 26.4% (221/836), respectively]. Improving the skills of endoscopic doctors (84.2%, 704/836), and enhancing the precision of pre-procedure evaluation and quality of multidisciplinary team (78.9%, 660/836) were considered urgent needs in the development of endoscopic treatment. Conclusion:A variety of endoscopic treatments for gastroesophageal varices in portal hypertension are implemented nationwide. Participant hospitals are active to perform emergent endoscopy for acute EGVB, but are inadequate in following recommendations regarding primary and secondary prophylaxis of EGVB. Moreover, the selection of endoscopic procedures for gastric varices differs greatly among hospitals.

This review systematically examines the pathophysiological effects of vasoactive medications on gastrointestinal tract of critically ill patients,the current value and safety of enteral nutrition in this patient's population,summarizes the optimal strategies for implementing enteral nutrition in these patients for clinical reference.

【Subjects】 To investigate the clinical application value of myocardial contrast echocardiography （MCE） in selecting CTO-PCI patients. MethodsFrom February 2019 to March 2020， a total of 50 patients with chronic coronary artery occlusion were consecutively selected as the research subjects. MCE and two-dimensional speck-tracking echocardiography were completed before and 12 months after interventional therapy. The primary end point was major adverse cardiovascular events. Patients were divided into groups according to the preoperative myocardial perfusion level of MCE. The improvement of left ventricular function was evaluated by two-dimensional echocardiography and left ventricular global longitudinal strain. ResultsCompared with the abnormal perfusion group， the improvement of GLS in the normal perfusion group was greater （P=0.028）. The wall motion score index （WMSI） of the abnormal perfusion group before PCI was higher than that of the normal perfusion group （P=0.002）. WMSI in the abnormal perfusion group was higher than that in the normal perfusion group one year after PCI （P<0.001）. The left ventricular GLS（P=0.008）.WMSI（P=0.016） and left ventricular end-diastolic volume（P=0.032） in the normal perfusion group were improved compared with those before operation； The postoperative perfusion score of patients with abnormal perfusion was significantly improved （ P=0.032）. ConclusionMCE has clinical application value in optimizing the selection of CTO-PCI patients. CTO patients with different myocardial perfusion types have different benefits after PCI.

Aim To investigate the effect of RORα antagonist T0901317 promoting EMT (epithelial-mesenchymal transition) of human gastric cancer MGC803 cells by RORα/β-catenin signal. Methods Cell proliferation was detected by MTT. Cell migration and invasion were detected by cell scratch and Transwell assay respectively. RORα/β-catenin signaling molecules were detected by Western blot and immunofluorescence. RORα binding to β-catenin protein was detected by immunoprecipitation. Results MTT assay showed that the proliferation ability of T0901317 cells increased in a time-dependent manner compared with MGC803 cells (P < 0. 05). Cell scratches and Transwell experiments showed that the migration and invasion ability of T0901317 cells were significantly enhanced compared with MGC803 cells (P < 0. 05). Western blot analysis showed that RORα protein was significantly down-regulated after T0901317 compared with untreated group (P < 0. 05), and total β-catenin protein and nuclear β-catenin in MGC803 cells were up-regulated after T0901317 (P < 0. 05). Compared with the control group, RORα protein binding to β-catenin protein significantly decreased after T0901317 treatment (P < 0. 05). Compared with MGC803 cells treated with T0901317, the long spindle cells increased and the heteromorphism was more obvious. T0901317 significantly up-regulated the expression of Rac1, TGFβ1 and Vimentin in MGC803 cells (P < 0. 05), and inhibited the expression of E-cadherin (P < 0. 05). Conclusion T0901317 can promote the proliferation, migration, invasion and EMT in human gastric cancer MGC803 cells by RORα/β-catenin signal.

Objective: To investigate the association of mixed exposure to greenness and nitrogen dioxide(NO₂) and hypertension among the older adults aged 65 years and over in China. Methods: The study subjects were from the Chinese Longitudinal Healthy Longevity Survey from 2017 to 2018. A total of 15 423 older adults aged 65 years and over meeting the criteria were finally included in the study. A questionnaire survey was used to collect information on demographic characteristics, lifestyle habits and self-reported prevalence of hypertension. Blood pressure values were obtained through physical examination. The level of normalized difference vegetation index(NDVI) was measured by the Medium-resolution Imaging Spectral Radiator(MODIS) of the National Aeronautics and Space Administration(NASA). The concentration of NO₂ was from China's surface air pollutant data set. Meteorological data was from NASA MERRA-2. The exposure to NDVI and NO₂ for each study subject was calculated based on the area within a 1 km radius around their residence. The association between mixed exposure of NDVI and NO₂ as well as their interaction and hypertension in older adults was analyzed by using the multivariate logistic regression model. The restrictive cubic spline(RCS) function was used to explore the exposure-response relationship between greenness and NO₂ and the risk of hypertension in study subjects. Results: The mean age of 15 423 older adults were (85.6±11.6). Women accounted for 56.3%(8 685/15 423) and 55.6%(8 578/15 423) lived in urban areas. The mean time of residence was (60.9±28.5) years. 59.8% of participants were with hypertension. The mean NDVI level was 0.41±0.13, and the mean NO₂ concentration was (32.18±10.36) μg/cm³. The results of multivariate logistic regression analysis showed that NDVI was inversely and linearly associated with the hypertension in older adults, with the OR(95%CI) value of 0.959(0.928-0.992). Compared with the T₁ group of NDVI, the risk of hypertension was lower in the T₃ group, with the OR(95%CI) value of 0.852(0.769-0.944), and the trend test was statistically significant(P<0.05). Compared with the T₁ group of NO₂, the risk of hypertension was higher in the T₂ and T₃ groups, with OR(95%CI) values of 1.160(1.055-1.275) and 1.244(1.111-1.393), and the trend test was statistically significant (P<0.05). The result of the RCS showed that NDVI was inversely and linearly associated with hypertension in older adults. NO₂ was nonlinearly associated with hypertension in older adults. The interaction analysis showed that NDVI and NO₂ had a negative multiplicative interaction on the risk of hypertension, with OR(95%CI) value of 0.995(0.992-0.997). Conclusion: Exposure to greenness and NO₂ are associated with hypertension in older adults.
