【Objective】 To investigate the application of different ureteral length measurement methods in the indwelling of double-J stent. 【Methods】 Clinical data of 260 patients with double-J stent indwelling after ureteroscopic surgery during Jul.2018 and Dec.2020 were prospectively analyzed. The patients were randomly divided into height calculation group, CT measurement group, KUB group and ureteroscopic measurement group. The length of ureter was calculated accordingly and the appropriate length of double-J stent was selected. KUB was performed on the first day after operation and before extubation to determine the position of double-J stent. The patients completed the ureteral stent-related symptom questionnaire (USSQ), urinary symptom score, lower urinary tract symptom (LUTS) score, pain score, hematuria score, and quality of life score before and after double-J catheter placement. 【Results】 There were no significant differences in age, gender, height, side of stent and urinary symptom score among the four groups (P>0.05). The average lengths of the ureters measured by the four methods were (21.5±1.0) cm, (21.5±1.8) cm, (23.8±1.3) cm and (21.7±1.8) cm, respectively. There were no significant differences among the height calculation group, CT measurement group and ureteroscope group, but there was significant difference between the three groups and the KUB group. The ideal ureteral stent length indwelling ratio in the ureteroscopic group was 76.9%, which was better than that in the other three groups. Postoperative indwelling time was 7-42 d (mean 29.8 d). The USSQ score of the ureteroscopic group before extubation was (14.1±1.5), which was lower than that of the other three groups (P<0.05). The ureteroscopic group was better than the other three groups in the comparison of frequency and urgency of urination, nocturia, hematuria, quality of life score, and pain score (P<0.05). 【Conclusion】 Intraoperative ureteroscopic measurement of the ureteral length is a simple and feasible method in guiding the indwelling of double-J stent to reduce ureteral stent related symptoms.

Pancreatic cancer is one of the digestive system tumors with a high degree of malignancy,and most of the patients are diagnosed in advanced stages.Because of limited available therapies,the mortality of this disease remains high.Tumor-associated macrophages(TAM),the main immune cells in the tumor microenvironment,are involved in the regulation of the occurrence and development of pancreatic cancer.Specifically,TAM are involved in the proliferation,invasion,immune escape,and chemoresistance of pancreatic cancer cells,demonstrating potential in the targeted therapy of pancreatic cancer.In this paper,we summarize the TAM-based therapies including consuming TAM,reprogramming TAM,dynamic imaging of TAM with nanoprobes,and regulating the phagocytic ability of TAM for pancreatic cancer,aiming to provide a theoretical basis for developing new therapies for pancreatic cancer.

OBJECTIVE:
To study the effect of traditional chinese medicine (TCM) compound on myeloid leukemia cells and to explore its anti-leukemic mechanism.
METHODS:
Myeloid leukemia cell lines were cultured in vitro and treated with TCM compound. The proliferation of the leukemia cells was measured by CCK8 method. The differentiation of the leukemia cells was evaluated by using Wright's staining method and by light microscopy, and the expression of differentiation-related surface antigens such as CD11B was measured and by flow cytometry, the apoptosis of the leukemia cells was detected by flow cytometry with using Annexin V staining.
RESULTS:
Compared with untreated 4 leukemia cell lines HL-60, MOLM-13, MV4-11, AML-M5, the proliferations of 4 leukemia cells treated with different concentrations of TCM compound decreased (P<0.05), and their proliferation inhibition were in a dose-dependent manner (r=0.9236; r=0.7488; r=0.8889; r=0.8119); compared with HL-60 and AML-M5 leukemia cells, the drug-treated 2 leukemia cells displayed obvious differentiated changes; compared with untreated HL-60 leukemia cell line, the expression of surface antigen CD11B increased by 85%±7.13% in HL-60 cells treated IC50 concentration of drug; compared with untreated AML-M5 leukemia cell line, the apoptotic rate of AML-M5 treated with 1.5 and 2 μl doses of TCM compound increased. (P<0.05).
CONCLUSION

In the field of bilingualism research, a key scientific question is how bilinguals process two language systems, particularly the effective switch from one language to another, namely bilingual code switching. With the rapid development of neuroimaging techniques, important progresses have been made in bilingual processing studies, especially in code switching. However, consensus has not been achieved regarding the mechanisms of bilingual code switching. Bilingual switching studies using neuropsychological and neuroimaging techniques have gained insights into the temporal and spatial features of the language switching process and the neurological mechanism, which provide direct evidence for the generation mechanism of bilingual code switching.

Objective To evaluate the role of preoperative serological indexes in predicting long-term survival and tumor recurrence of hepatocellular carcinoma (HCC) patients after liver transplantation, aiming to explore its significance in expanding the Milan criteria. Methods Clinical data of 669 recipients undergoing liver transplantation for HCC were retrospectively analyzed. The optimal cut-off value was calculated by the receiver operating characteristic (ROC) curve. The risk factors affecting the overall survival and recurrence-free survival rates of HCC patients after liver transplantation were identified by univariate and multivariate regression analyses. The correlation between preoperative serum liver enzymes and pathological characteristics in HCC patients was analyzed. The predictive values of alpha-fetoprotein (AFP) combined with γ -glutamyl transferase (GGT) and different liver transplant criteria for the survival and recurrence of HCC patients after liver transplantation were compared. Results Exceeded Milan criteria, total tumor diameter (TTD) > 8 cm, AFP > 200 ng/mL and GGT > 84 U/L were the independent risk factors for the overall survival and recurrence-free survival rates of HCC patients after liver transplantation (all
