Objectives To evaluate the complications predicting efficacy of the American College of Surgeons(ACS)National Surgical Quality Improvement Program(NSQIP)surgical risk calculator for cervical cancer patients undergoing open radical hysterectomy in China.Methods This study enrolled the cervical cancer patients(139 cases)undertaken open radical hysterectomy at Women's Hospital of Nanjing Medical University from Janu-ary to December in 2021.Preoperative risk factors were abstracted from medical records and the surgical risk scores were calculated using ACS NSQIP surgical risk calculator.The association between risk scores and actual outcomes were assessed using logistic regression together with the c-statistic(area under ROC)and Brier score.Results The ACSNSQIP calculator did not predict accurately for serious complications,any complications,venous thrombo-embolism(VTE),readmission,return operation room and surgical site infection(SSI)compared with actual out-comes.There was significantly difference in the predicted and actual length of stay(3.93±0.42 days vs.13.11±4.71 days,P<0.001).Conclusions The ACS NSQIP surgical risk calculator failed to predict the postoperative complications and the length of hospital stay for cervical cancer patients undergoing open radical hysterectomy.

Bacterial biofilm refers to a tunicate-like biological group composed of polysaccharide, protein and nucleic acid secreted by bacteria on the surface of the mucous membrane or biological material. The biofilm formation is a major cause of chronic infections. Bacteria could produce some secondary metabolites during the growth and reproduction. Some of them act as signaling molecules allowing bacteria to communicate and regulate many important physiological behaviors at multiple-cell level, such as bioluminescence, biofilm formation, motility and lifestyles. Usually, these signal molecules play an important role in the formation of bacterial biofilm. We review here the effects of related signal molecules of Quorum Sensing, cyclic diguanylate, Two-Component Systems and sRNA on the biofilm formation. Focusing on these regulation mechanism of signal molecules in the process of biofilm formation is necessary for the prevention and treatment of some chronic diseases.

【Objective】 To analyze the composition of urinary calculi in Longnan, Gansu province, and the relationship between the composition and clinical characteristics of patients, so as to provide reference for the prevention and treatment of this disease. 【Methods】 The composition of 500 cases of urinary calculi hospitalized in our department during Apr. 2021 and Feb.2023 were analyzed using the infrared spectrum stone composition analyzer. The clinical characteristics of the patients were evaluated and analyzed. 【Results】 The male-to-female ration of patients was 2.70∶1. Most patients aged 21 to 60 years (437, 87.4%). Most cases were ureteral calculi (72.8%), followed by renal calculi (22.2%), and bladder calculi (5.0%). There were 166 cases of calcium oxalate calculi, 293 cases of calcium oxalate + carbonated apatite calculi, 24 cases of calcium oxalate + carbonated apatite + hydroxyl apatite calculi, 4 cases of calcium oxalate + calcium bicarbonate calculi, 7 cases of urate calculi, 6 cases of carbonated apatite + struvite calculi. Oxalate calculi were the most common in all age groups, and urate calculi were the most common in the 21 to 40 age group. Calcium oxalate calculi were most common in the ureter (127, 76.5%), significantly higher than in other sites (χ2=3.222, P=0.020). Calcium oxalate + calcium hydrogen phosphate calculi was the least common in the bladder, significantly different from the other parts (χ2=2.092, P=0.037). Magnesium ammonium phosphate hexahydrate and/or calcium carbonate or calcium oxalate calculi were the most common in the kidney (50.0%), significantly different from the other parts (χ2=9.448, P=0.007). 【Conclusion】 In Longnan area, the incidence of urinary calculi is significantly higher in male than in female. Ureteral calculi are mainly composed of calcium oxalate + carbonated apatite and calcium oxalate. According to different risk factors, individual prevention programs should be developed.

Prostate cancer (PCa) is one of the most common malignant tumors in the male genitourinary system. The phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway is a carcinogenic pathway responsible for the migration, proliferation, and drug resistance of various cancers. In recent years, as the research on the pathogenesis of PCa is deepening, the role of the PI3K/Akt signaling pathway in the development of PCa has attracted much attention. Traditional Chinese medicine, comprehensively regulating multiple components, targets, and pathways, has shown great potential in the treatment of PCa. This article reviews the research progress of traditional Chinese medicine targeting the PI3K/Akt signaling pathway in the treatment of PCa and discusses the expression of the PI3K/Akt signaling pathway in PCa, which involves inhibiting apoptosis of PCa cells, promoting the cell cycle, invasion, and migration of PCa cells, promoting tumor tissue angiogenesis, and mediating the androgen receptor. Additionally, it summarizes the single Chinese medicines that target and regulate this pathway, including Hedyotis diffusa, Taxus chinensis, Bovisc Alculus, and Atractylodis Macrocephalae Rhizoma. The active ingredients of these Chinese medicines mainly include flavonoids, alkaloids, terpenes, polyphenols, lignans, and other compounds. The Chinese medicine compound prescriptions targeting the PI3K/Akt pathway mainly include Wenshen Sanjie prescription, Jianspi Lishi Huayu prescription, Yishen Tonglongtang, Qilan prescription, Xihuangwan, and modified Shenqi Dihuangtang. This review is expected to provide a scientific basis for deeply understanding the pathogenesis of PCa and identifying potential therapeutic targets, as well as to provide new ideas for clinical research and drug development for PCa.
