Objective:To investigate the efficacy and safety of darolutamide in the treatment of patients with metastatic hormone-sensitive prostate cancer.Methods:A retrospective analysis was conducted on 17 cases of prostate cancer patients who received treatment with darolutamide in combination with ADT at our hospital from January to December 2022. The median age was 70 (range: 56 to 92) years old. The median pre-treatment prostate-specific antigen (PSA) level was 63.50 (range: 29.16 to 700.74) ng/ml. Sixteen cases had a Gleason score of 8 or above, and 11 cases were classified as high tumor burden (with four or more bone metastases and/or visceral metastases). The patients were treated with darolutamide in combination with goserelin (10.8 mg, subcutaneous injection, every 12 weeks). The decrease in PSA levels was observed at 2 weeks and at 1, 2, 3, and 6 months post-treatment. The time to achieve a 50% decrease in PSA level (PSA50), a 90% decrease (PSA90), and a PSA level of ≤0.2 ng/ml was recorded.Adverse drug reactions were also documented.Results:All the 17 patients were followed up and continued to receive darolutamide at our center without any loss to follow-up. The median follow-up time was 11.4(8.9, 15.3)months. It showed a median PSA decrease from baseline of 83.33% at 2 weeks, 95.37% at 1 month, 96.71% at 2 months, 97.22% at 3 months, and 99.10% at 6 months. The median time to achieve PSA50, PSA90, and PSA ≤ 0.2 ng/ml were 1.3 (0.9, 1.7)months, 1.7 (1.2, 2.4)months, and 3.6 (2.9, 4.5)months respectively. Six patients with bone metastases experienced relief of metastatic lesions after treatment. Only one patient developed papules on the left upper limb, which were assessed as grade 1 rash, and the rash disappeared after three days treatment of topical application of hydrocortisone cream.Conclusions:Darolutamide could rapidly control and significantly reduce PSA levels in prostate cancer patients, with a favorable safety profile.

Objective:To investigate impacts of paeoniflorin on inflammation and nuclear transcription factor-κB(NF-κB)/nucleotide-binding oligomeric domain-like receptor protein 3(NLRP3)signal pathway in knee osteoarthritis(KOA)model rats.Meth-ods:SD rats were randomly grouped into model group,glucosamine group,paeoniflorin low-dose group,paeoniflorin high-dose group,paeoniflorin high-dose+phorbol ester(PMA)(NF-κB activator)group,with 10 rats in each group,another 10 rats were regarded as control group,and only knee joint capsule was cut,after treatment with glucosamine,paeoniflorin and PMA,joint pain symptoms of rats were detected by mechanical stimulation method and thermal radiation method;knee joint width,joint swelling and synovial thick-ness were measured;HE staining was applied to detect joint tissue structure and morphology of rats in each group;levels of inflamma-tory factors IL-1β,monocyte chemoattractant protein 1(MCP-1)and IL-9 in joint fluid and serum of rats were detected by ELISA;and Western blot was applied to detect expressions of NF-κB/NLRP3 signal pathway related proteins in rat joint tissue.Results:Com-pared with control group,joint tissue structure of model group was significantly damaged,mechanical pain threshold and thermal sen-sitivity pain threshold were significantly lower(P<0.05),knee joint width,joint swelling and synovial thickness,levels of IL-1β,MCP-1 and IL-9 in joint fluid and serum,and expression of p-NF-κB p65/NF-κB p65 and NLRP3 proteins in joint tissue were higher(P<0.05).Compared with model group,joint tissue damage of rats in glucosamine group,paeoniflorin low-dose group and paeoniflorin high-dose group was reduced,mechanical pain threshold and thermal sensitivity pain threshold were higher(P<0.05),knee joint width,joint swelling and synovial thickness,levels of IL-1β,MCP-1 and IL-9 in joint fluid and serum,and expressions of p-NF-κB p65/NF-κB p65 and NLRP3 proteins in joint tissue were lower(P<0.05);joint tissue injury of rats in paeoniflorin high-dose group was further reduced compared with paeoniflorin low-dose group,mechanical pain threshold and thermal sensitivity pain threshold were further higher(P<0.05),knee joint width,joint swelling and synovial thickness,levels of IL-1β,MCP-1 and IL-9 in joint fluid and serum,and expression of p-NF-κB p65/NF-κB p65 and NLRP3 proteins in joint tissue were further lower(P<0.05).Compared with paeoniflorin high-dose group,joint tissue damage of rats in paeoniflorin high-dose+PMA group was increased,mechanical pain threshold and thermal sensitivity pain threshold were lower(P<0.05),knee joint width,joint swelling and synovial thickness,levels of IL-1β,MCP-1 and IL-9 in joint fluid and serum,and expression of p-NF-κB p65/NF-κB p65 and NLRP3 proteins in joint tissue were higher(P<0.05);there was no significant change in all indexes of rats in glucosamine group(P>0.05).Conclusion:Paeoniflorin can play an anti-inflammatory role by down-regulating the NF-κB/NLRP3 signal pathway,thus alleviating joint injury and joint pain symptoms of KOA rats.

Objective To investigate the effect of ACOT4 expression on the formation of calcium oxalate stones.Methods The HK2 cell of human tubular epithelial cells was used as subject,HK2 cell was treated with calcium oxalate,and the expression of ACOT4 was interfered with by siRNA.The gene expression levels in HK2 cell were detected by qPCR and Western blot.The cell viability was de-tected by CCK-8 assay.The cell apoptosis was detected by flow cytometry.The cell damage was detected by LDH assay.The adhesion ability of HK2 cell to calcium oxalate crystals was detected by crystal adhesion experiment.Results Calcium oxalate could regulate the expression of ACOT4 in HK2 cell.Interfering with ACOT4 can significantly inhibit the proliferation ability of HK2 cell,and promote the effect of cell activity reduction,damage and apoptosis of calcium oxalate to HK2 cell.At the same time,interfering with ACOT4 can sig-nificantly promote the adhesion ability of HK2 cells to calcium oxalate crystals.Conclusion Knocking down of ACOT4 can promote the damage of calcium oxalate to HK2 cell and promote the adhesion ability of HK2 cell to calcium oxalate crystals.

This article retrospectively analyzed the clinical data of 8 patients with vesicovaginal fistula after radiotherapy for cervical cancer admitted in our hospital from January 2015 to October 2021. All of them underwent cystostomy under local anesthesia. A single J tube of bilateral ureters was retained under cystoscope, and the single J tube was introduced into the fistula bag through the cystostomy opening. All patients wore diapers for a long time before operation, and used urine pads 0-2 pieces/day after operation. QOL score was 5.3±0.5 points before operation, and 2.5±0.5 points after operation. The patient's body odor basically disappeared. The vesicovaginal fistula can be repaired by surgery, but for patients who cannot be operated or failed repeatedly due to various reasons, a single J tube of bilateral ureters can be drawn out through the cystostomy opening, which can improve the quality of life of patients through minor trauma.

Objective:To investigate the safety and efficacy of submucosal tunnel docking endoscopic resection (SDER) for the treatment of giant submucosal tumors in the cardia.Methods:A retrospective analysis was performed on data of patients with giant submucosal tumors in the cardia who were treated with SDER at the endoscopy center of Zhongshan Hospital, Fudan University and Xuhui District Central Hospital from January 2021 to January 2022. The surgical records, postoperative pathology, complications, hospitalization, and follow-up were analyzed.Results:A total of 6 patients were included. The mean long diameter of the lesions was 4.0 cm, all of which were located in the cardia. All patients successfully underwent SDER treatment with a surgical time of 23-42 min. Postoperative pathology revealed that 4 cases were leiomyomas and 2 cases were gastrointestinal stromal tumors. All lesions were completely resected. The postoperative hospital stay was 3-5 d, and no serious complications occurred after surgery. All patients recovered on follow-up gastroscopy at 3 and 6 months postoperatively.Conclusion:The preliminary conclusion is that SDER for the treatment of giant submucosal tumors in the cardia is safe, effective.

Purpose: Although drug-coated balloon (DCB) treatment is known to be effective for de novo lesions, the influence of sex on angiographic and clinical outcomes remains unknown. This study aimed to investigate the angiographic and clinical impact of DCB treatment in patients with de novo coronary lesions according to sex. Materials and Methods: A total of 227 patients successfully treated with DCB were retrospectively enrolled and divided into two groups according to sex. The primary endpoint was late lumen loss (LLL) at 6-month angiography, and the secondary endpoint was target vessel failure (TVF), which included cardiac death, target vessel myocardial infarction, target lesion revascularization, and target vessel thrombosis. Results: The study enrolled 60 women (26.4%) and 167 men (73.6%). Compared to men, women had a smaller vessel size, larger DCB to reference vessel ratio, and more dissections after DCB treatment (55.0% vs. 37.1%, p=0.016). Women also had a significantly higher LLL compared to men (0.12±0.26 mm vs. 0.02±0.22 mm, p=0.012) at the 6-month follow-up angiography. During a median follow-up of 3.4 years (range 12.7–28.9 months), TVF was similar (women 6.7% vs. men 7.8%, p=0.944). In multivariable analysis, women were independently associated with a higher LLL. Conclusion LLL was higher in women, but there was no difference in TVF between women and men. Based on multivariable analysis, the women sex was an independent predictor of higher LLL (Impact of Drug-coated Balloon Treatment in de Novo Coronary Lesion; NCT04619277).

Objective:To investigate the epidemiological characteristics and current status of surgical management for esophageal cancer in China.Methods:A national database was setup through a network platform. The clinical data of esophageal cancer treated by surgery was collected from 70 major hospitals in China between January 2009 and December 2014.Results:Complete data of 8 181 cases of esophageal cancer patients who underwent surgery were recorded in the database and recruited in the analysis. Among them, 6 052 cases were male and 2 129 were female, the average age was 60.5 years.The epidemiological investigation results showed that 148 cases (1.8%) had history of psychological trauma, 7 527 cases (92.0%) were lower social economic status, 5 072 cases (62.0%) were short of fresh vegetables and fruits, 6 544 cases (80.0%) ate rough food frequently, 3 722 cases (45.5%) drank untreated water directly from lake or river or shallow well, 3 436 cases (42.0%) had a unhealthy eating habit, including habits of eating food fast (507 cases, 6.2%), eating hot food or drinking hot tea/soup (998 cases, 12.2%), eating fried food (1 939 cases, 23.7%), 4 410 cases (53.9%) had the habits of smoking cigarettes and 2 822 cases (34.5%) drank white wine frequently.The pathological results showed that 7 813 cases (95.5%) were squamous cell carcinoma, 267 cases were adenocarcinoma (3.3%), 25 cases were adenosquamous cell carcinoma (0.3%) and 50 cases were small cell carcinoma (0.6%). A total of 1 800 cases (22.0%) received preoperative neoadjuvant therapy due to locally advanced disease or difficulty of resection. The esophagectomies were performed through left thoracotomy approach in 5 870 cases (71.8%), through right chest approach in 2 215 cases (27.1%), and the remain 96 cases (1.2%) received surgery though other approaches.A total of 8 001 cases (97.8%) underwent radical resection, the other 180 cases (2.2%) received palliative resection. The 30-day postoperative mortality rate was 0.5%, the overall ≥ grade Ⅱ postoperative complication rate was 11.6% (951 cases). The 1-yr, 3-yr, and 5-yr overall actual survival rates were 82.6%, 61.6%, and 52.9%, respectively.Conclusions:The data analysis of the national database for esophageal cancer shows that bad eating habits or eating rough food without enough nutrients, lower social and economic status, drinking white wine and smoking cigarettes frequently may be correlated with tumorigenesis of esophageal cancer. However, strong evidences produced by prospective observation studies are needed. Overall, the long-term survival of esophageal cancer patients has been improved gradually due to the application of advanced surgical techniques and reasonable multimodality treatment.
