Prompt gamma rays are a kind of secondary radiation produced in particle therapy, and prompt gamma information largely reflects the incidence of particles. Consequently, use of prompt gamma information to verify the range of particles is a promising verification method. In this article, the concept of prompt gamma ray in vivo range verification and the advantages of prompt gamma verification over existing methods were introduced. Secondly, the progress in developing a method for range verification using prompt gamma in recent years was reviewed, and the advantages and disadvantages of three methods including prompt gamma imaging (PGI), prompt gamma timing (PGT) and prompt gamma spectroscopy (PGS) were discussed. Finally, these three methods were summarized, and the development trend of prompt gamma rays for in vivo range monitoring was prospected.

Objective To identify Chinese character writing related cortex (WRC) and its relationship with hand motor cortical areas. Methods Ten native Chinese-speaking, right-hand volunteers were recruited in the study. NTMS mapping was conducted during picture naming task. The WRC were mapped based on nTMS-induced impairment of Chinese character writing. The extent and area of WRC was calculated. The right-hand motor representations were mapped while motor-evoked potentials were produced under nTMS stimulation. EMG data and coordinates of positive stimulus were recorded. The relationship between WRC and hand motor cortex (HMC) was analyzed on the basis of area comparison and distance calculation. Results The cortical areas related to Chinese character writing were mapped successfully in all subjects by nTMS. WRC was primarily centered in left posterior middle frontal gyrus (pMFG) (86%,55/64). The mean WRC area (161.03 mm2 ±62.58mm2) was significantly smaller than the mean HMC area (589.50 mm2±227.34mm2) (P<0.001). The WRC and HMC were not conjoined or overlapped in the dominant hemisphere. The distance between those two was 12.58mm±2.71mm. Conclusions NTMS can provide reliable assistance in mapping WRC areas. The WRC is relatively fixed and centralized in pMFG but is not overlapped with the HMC.

Objective:
Aimed to construct an immune-related risk signature and nomogram predicting endometrial cancer (EC) prognosis.
Methods:
An immune-related risk signature in EC was constructed using the least absolute shrinkage and selection operator regression analysis based on The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases. A nomogram integrating the immune-related genes and the clinicopathological characteristics was established and validated using the Kaplan-Meier survival curve and receiver operating characteristic (ROC) curve to predict the overall survival (OS) of EC patients. The Estimation of STromal and Immune cells in MAlignant Tumor tissues using Expression data (ESTIMATE) R tool was used to explore the immune and stromal scores.
Results:
CCL17, CTLA4, GPI, HDGF, HFE2, ICOS, IFNG, IL21R, KAL1, NR3C1, S100A2, and S100A9 were used in developing an immune-related risk signature evaluation model. The Kaplan-Meier curve indicated that patients in the low-risk group had better OS (p<0.001).The area under the ROC curve (AUC) values of this model were 0.737, 0.764, and 0.782 for the 3-, 5-, and 7-year OS, respectively. A nomogram integrating the immune-related risk model and clinical features could accurately predict the OS (AUC=0.772, 0.786, and 0.817 at 3-, 5-, and 7-year OS, respectively). The 4 immune cell scores were lower in the high-risk group. Forkhead box P3 (FOXP3) and basic leucine zipper ATF-like transcription factor (BATF) showed a potential significant role in the immune-related risk signature.
Conclusion
Twelve immune-related genes signature and nomogram for assessing the OS of patients with EC had a good practical value.

Objective:
This study aims to analyze factors associated with lymphovascular space invasion (LVSI) and evaluate the prognostic significance of LVSI in Chinese endometrioid endometrial cancer (EEC) patients.
Methods:
Five-hundred eighty-four EEC patients undergoing surgery in our center from 2006 to 2016 were selected for analysis. Univariate analysis and multivariate logistic regression were used to examine relevant factors of LVSI. To evaluate the prognostic role of LVSI, survival analyses were conducted. In survival analyses, both multivariate Cox regression and propensity score matching were used to control the confounders.
Results:
The incidence of LVSI was 12.16% (71/584). Diabetes history (p=0.021), lymph node metastasis (p=0.005), deep myometrial invasion (p<0.001) and negative PR expression (p=0.007) were independently associated with LVSI. Both Kaplan-Meier method and univariate Cox regressions showed LVSI negative and positive cases had similar tumor-specific survival (TSS) and disease-free survival (DFS). After adjusting for the influence of adjuvant therapy and other clinicopathological factors with multivariate Cox regressions, LVSI still could not bring additional survival risk to the patients (p=0.280 and p=0.650 for TSS and DFS, respectively). This result was verified by Kaplan-Meier survival analyses after propensity score matching (p=0.234 and p=0.765 for TSS and DFS, respectively).
Conclusion
LVSI does not significantly compromise the survival outcome of Chinese EEC patients.

Objective To make bibliometrics analysis on case management literature in China so as to understand the research hotspots of case management and provide a basis for development of case management. Methods Journal articles related to case management were retrieved based on the theme "Case Management"in Chinese National Knowledge Infrastructure (CNKI) from 1st January 2009 to 31st December 2018 and the bibliography was collected. Excel and self-design computer program were used to frequency statistics and to construct co-word analysis and co-occurrence matrix of high-frequency keywords. SPSS 22.0 was used to hierarchical cluster analysis. Results A total of 1 102 articles were included and 53 high-frequency keywords were extracted. From 2009 to 2018, case management applied research showed growth trend in China. A total of 988 authors published 1 102 articles in 531 journals. Hierarchical cluster analysis showed that research hotspots of case management in China focused on 8 aspects including community-based rehabilitation, Aids, chronic heart failure, diabetes, peritoneal dialysis, chronic obstructive pulmonary disease, human resources and social work. Conclusions Nearly 10 years, case management is widely used in nursing field and social work, but research depth and width is insufficient. Achievable case management scheme should be built and informative case management system should be constructed to improve prognosis and quality of life of patients. There is still large room for development in the future.

Objective:To evaluate short-term clinical efficacy of femoral neck system (FNS) for treatment of femoral neck fractures in young and middle-aged patients.Methods:A retrospective analysis was conducted of the 70 middle-aged and young patients who had been surgically treated for femoral neck fractures at Department of Trauma Orthopaedics, Honghui Hospital from January to November 2020. Of them, 32 cases were fixated by FNS; they were 16 males and 16 females, with an age of (49.4±11.0) years, including 10 cases of type Ⅱ, 12 cases of type Ⅲ and 10 cases of type Ⅳ by the Garden classification. The other 38 patients were fixated by cannulated compression screws (CCS); they were 19 males and 19 females, with an age of (48.8±10.1) years, including 12 cases of type Ⅱ, 15 cases of type Ⅲ and 11 cases of type Ⅳ by the Garden classification. The 2 groups were compared in terms of operation time, intraoperative blood loss, fracture reduction, fracture union time, weight-bearing time, complications, Barthel index at 3 months after surgery, and hip function at 6 months after surgery.Results:There was no statistically significant difference in preoperative general information or follow-up time between the 2 groups, showing comparability between groups ( P>0.05). There was no significant difference in operation time, intraoperative blood loss or fracture reduction quality between the 2 groups ( P>0.05). In the FNS group, weight-bearing time [(11.4±3.4) weeks] and fracture healing time [(3.1±0.9) months] were significantly shorter than those in the CCS group [(16.4±3.9) weeks and (3.6±0.9) months], rate of complications (12.5%, 4/32) was significantly lower than that in the CCS group (34.2%, 13/38), Barthel index at 3 months after operation (98.1±2.8) and Harris hip score at 6 months after operation (96.8±4.0) were significantly higher than those in the CCS group (93.8±4.1 and 93.6±6.7) ( P<0.05). Conclusion:In the treatment of femoral neck fractures in young and middle-aged patients, compared with CCS fixation, FNS fixation can obtain better short-term curative effects, due to its advantages of shorter bone union and weight-bearing time, a decreased rate of complications and early functional recovery of daily activities.

Objective:To explore the value of dual-layer spectral detector CT in differentiating the diagnosis of lung cancer and inflammatory nodules.Methods:A total of 92 patients undergoing enhanced chest scan from March 2019 to September 2020 at Renji Hospital, School of Medicine, Shanghai Jiaotong University, were retrospectively enrolled in the study. The conventional CT parameters, spectral CT parameters were measured and the nodules′ morphological characteristics were analyzed. Later the factors with statistical significance were identified as independent variables in a logistic regression model to establish models for predicting malignant nodules. ROC curve was used to assess the diagnostic performance for the conventional CT model, spectral CT parameters and combined model, respectively. Differences in the area under the ROC curve (AUC) were analyzed by the DeLong test.Results:Lobulated sign (42 and 8, respectively, χ2=10.779, P=0.001), short burr sign (41 and 7, respectively, χ2=11.911, P=0.001), pleural indentation sign (45 and 9 respectively, χ2=11.705, P=0.001), vascular convergence sign (35 and 8, respectively, χ2=5.337, P=0.021) and the venous phase iodine concentrations (IC) value [(2.1±0.5) mg/ml, (2.3±0.5) mg/ml, t=-2.464, P=0.016], normalized iodine concentrations (NIC) value (0.40±0.06, 0.45±0.08, t=-6.943, P<0.001), and Z-effective (Z eff) values (8.38±0.21, 8.49±0.19, t=-2.122, P=0.037) were significantly different between the lung cancer group and the inflammatory group, while other CT signs and CT indicators were not significantly different between the lung cancer group and the inflammatory group ( P>0.05). The conventional CT model was established with lobulated sign, short burr sign, pleural indentation sign, vascular convergence sign, and the AUC for differential diagnosis of lung cancer and inflammatory nodules was 0.827. The spectral CT parameter model was established with venous phase IC, venous phase NIC, and venous phase Z eff value, and the AUC for differential diagnosis of lung cancer and inflammatory nodules was 0.899. The conventional CT model combined spectral CT parameter model was established with the significant factors in the univariate analysis, and the AUC for differential diagnosis of lung cancer and inflammatory nodules was 0.925. The AUC of the combined model showed no significant difference from that of the spectral CT parameter model ( Z=1.794, P=0.073). However, AUC of the combined model was significantly higher than that of evaluation based on conventional CT alone ( Z=2.156, P=0.031). Conclusion:Spectral CT parameters combined with conventional CT signs can improve the differential diagnosis efficiency between lung cancer and inflammatory nodules.
