AIM:To evaluate the efficacy,safety,and economy of camrelizumab(CAM)combined with platinum-containing chemotherapy(CT)for the first-line treatment of locally advanced/meta-static non-small cell lung cancer(NSCLC).METH-ODS:Chinese and English databases such as Pubmed,the Cochrane Library,China Knowledge Network,Wanfang Data,and other related web-sites were systematically searched.After literature screening,quality assessment,and data extraction of the literature according to the inclusion and ex-clusion criteria,two researchers conducted a rapid health technology assessment(HTA).RESULTS:A total of 7 systematic evaluations/Meta-analyses and 17 economics evaluations were included.In terms of effectiveness,compared to docetaxel che-motherapy,CAM+CT significantly prolonged the overall survival(OS),progression-free survival(PFS),and improved the objective remission rate(ORR)of mutation-negative patients with locally ad-vanced/metastatic NSCLC.Compared with CT and pembrolizumab(PEM),CAM+CT significantly pro-longed the PFS,and improved the ORR of mutation-negative patients with locally advanced/metastatic NSCLC.Subgroup analysis showed that CAM+CT significantly prolonged PFS in patients with PD-L1 ≥1％and PD-L1 ≥ 50％compared with CT.Compared with CT,CAM+CT significantly prolonged the OS and PFS of mutation-negative patients with locally advanced/metastatic squamous NSCLC.Compared with sintilimab(SIN),CAM+CT significantly pro-longed the PFS of mutation-negative patients with locally advanced/metastatic squamous NSCLC.Sub-group analysis showed that CAM+CT significantly prolonged OS in patients with PD-L1＜1％com-pared with CT.In terms of safety,CAM+CT was comparable in terms of the occurrence of all grades of adverse events,but the incidence of grade 3 or higher treatment-related adverse events was significantly increased compared with CT and PEM for mutation-negative locally advanced/meta-static NSCLC patients.CAM+CT was significantly in-creased the occurrence of all grades of adverse events compared with CT,but was comparable in terms of the occurrence of grade 3 or higher treat-ment-related adverse events.In terms of economy,CAM+CT has a cost-effectiveness advantage over CT for patients with mutation-negative advanced/metastatic squamous NSCLC.CAM+CT has a cost-effectiveness advantage over CT and PEM+CT;and CAM+CT does not have a cost-effectiveness ad-vantage over SIN+CT for patients with mutation-negative locally advanced/metastatic non-squa-mous NSCLC.CONCLUSION:CAM+CT has good ef-ficacy and cost-effectiveness for the first-line treat-ment of locally advanced/metastatic NSCLC,and the safety aspect is compared with CT,PEM or slightly worse.

Objective:To explore the diagnostic value of improved 18F-prostate specific membrane antigen (PSMA)-1007 PET-CT score (referred to as PSMA score) and multi parameter magnetic resonance imaging (mpMRI) prostate imaging reporting and data system (PI-RADS) score (referred to as PI-RADS score) for primary prostate cancer (PCa). Methods:A retrospective case series study was conducted. The imaging and clinical data of 134 suspected PCa patients underwent 18F-PSMA-1007 PET-CT and mpMRI examinations at Shanxi Province Cancer Hospital from July 2018 to May 2023 were collected. Pathological diagnosis showed 92 cases of PCa and 42 cases of benign prostatic lesions. The clinical and imaging parameters, as well as the distribution of patients with two scores, were compared between the two groups. The blind diagnosis of benign and malignant lesions was made based on the improved PSMA score (dividing 1 point into 1a and 1b points, 1b, 2 and 3 points were diagnosed as PCa), PI-RADS score (3, 4 and 5 points were diagnosed as PCa) and the combination of the two (diagnosed as PCa when either PSMA score ≥ 1b point or PI-RADS score ≥ 4 points was met). The indicators of the diagnostic efficiency of PSMA score, PI-RADS score and the combination of the two for PCa were calculated. Using pathological results as the gold standard, the receiver operating characteristic (ROC) curve of PSMA score, PI-RADS score and the combination of the two for diagnosing PCa was drawn, and the diagnostic efficiency of the 3 methods was analyzed. Results:The age, serum prostate-specific antigen, and maximum standard uptake value of PET-CT in the PCa group were higher than those in the benign prostatic lesion group, and the differences were statistically significant (all P < 0.05). The sensitivity, specificity, accuracy, false negative rate, false positive rate, positive predictive value, and negative predictive value of PSMA score for diagnosing PCa were 91.30% (84/92), 80.95% (34/42), 88.06% (118/134), 8.70% (8/92), 19.05% (8/42), 91.30% (84/92), and 80.95% (34/42), respectively; those of PI-RADS score were 93.48% (86/92), 61.90% (26/42), 83.58% (112/134), 61.90% (26/42), 38.10% (16/42), 84.31% (86/102), and 81.25% (26/32), respectively; those of the combination of the two were 97.83% (90/92), 88.10% (37/42), 94.78% (127/134), 2.17% (2/92), 11.90% (5/42), 94.74% (90/95), and 94.87% (37/39), respectively. The differences in specificity, accuracy, false negative rate, and false positive rate among the 3 methods were statistically significant (all P < 0.05). ROC curve analysis showed that the area under the curve of PSMA score, PI-RADS score and the combination of the two for diagnosing PCa were 0.930 (95% CI: 0.872-0.967), 0.935 (95% CI: 0.826-0.939) and 0.959 (95% CI: 0.910-0.986), respectively, and the differences between each two methods were statistically significant (all P < 0.05); the sensitivity of PSMA score, PI-RADS score and the combination of the two was 90.11%, 89.13% and 98.09%, and the specificity was 90.48%, 90.48% and 92.09%. Conclusions:Compared with the PI-RADS score, the improved PSMA score can improve the specificity and accuracy of PCa diagnosis, and decrease the false negative and false positive rates; the diagnostic efficiency of the combination of the two is superior.

Follicular lymphoma (FL) is highly heterogeneous with different histopathologic grades. Its biological characteristics and clinical management are different. This study retrospectively analyzed 18F-FDG PET-CT metabolic parameters, clinical features, and their relationship with prognosis in 161 FL patients with different histopathological grades (grade 1-2, grade 3A, grade 3B) at the Shanxi Cancer Hospital. There were 93 cases in the grade 1-2 group, 40 cases in the grade 3A group, and 28 cases in the grade 3B group. The expression of LDH, CD10, EZH2, c-Myc, and CD37 proteins was correlated with histological grade (grade 1-2, grade 3A, and grade 3B) (all P values<0.05) . The SUVmax, TLG, TBR, and TLR for the three groups were different (all P values<0.05) . The optimal thresholds of SUVmax, MTV, TLG, TBR, and TLR for predicting FL disease progression were 8.32, 201.31, 2 342.55, 6.56, and 3.52, respectively, and the rate of disease progression increased in patients with higher thresholds (all P value<0.05) . β 2-MG (>2.3 μg/L) , Follicular lymphoma international prognostic index-1 (FLIPI-1) score (3-5 points) , negative CD37 expression, positive c-Myc expression, and TLG (>2 342.55 g) were all independent risk factors for PFS in the FL patients ( HR=3.609, 2.509, 0.255, 3.506, 13.531, all P value<0.05) . 18F-FDG PET-CT is a powerful complement to FL histopathological grading and the combination of the two may better predict the prognosis of FL patients.

ObjectiveTo investigate whether elemene（ELE） enhances the anti-glioma efficacy of cabazitaxel（CTX）， and prepare a double-targeted cationic liposome（LIP） co-loaded with ELE/CTX for the treatment of glioma， and to achieve the effect of increasing the efficacy and reducing the adverse reactions. Pharmacodynamic tests in vitro were performed to explore the advantages and mechanism of its preparation. MethodELE/CTX@LIP was prepared by high speed shear combined with probe ultrasound， the particle size and potential were characterized by nano-particle size potentiometer， and high performance liquid chromatography（HPLC） was used to determine the encapsulation efficiency and drug loading capacity of CTX/ELE. The cytotoxicity of ELE/CTX in vitro was detected by cell proliferation and activity assay（CCK8）. JMP Pro 16 software was used to optimize the process parameters of ELE/CTX@LIP based on encapsulation efficiency. The optimal cationic material type， content and ratio were screened by in vitro cytotoxicity and in vitro cell uptake， on this basis， the dual-targeted cationic liposome T7/arginine glycine aspartate tripeptide sequence（T7/cRGD）-ELE/CTX@CLIP was prepared， the stability of morphology and particle size were characterized， and the effect of T7/cRGD-ELE/CTX@CLIP on the apoptosis inducing ability and cell cycle regulation ability of glioma cells was analyzed by cell cycle and apoptosis. ResultELE/CTX showed stronger anti-glioma activity on C6 and RG2 cells. The results of in vitro cytotoxicity and in vitro cell uptake showed that the amount of cationic material was 0.10% of the total content. The optimum ratio of T7， cRGD and phospholipids was 1∶1∶50. T7/cRGD-ELE/CTX@CLIP［1，2-dilinoleyloxy-3-dimethylaminopropane（Dlin-MC3-DMA）］ and T7/cRGD-ELE/CTX@CLIP［1，2-dimyristoyl-rac-glycero-3-methoxypolyethylene glycol 2000（DMG-PEG2000）］ showed multi-level spherical nanostructures with particle sizes of 146.0， 111.3 nm， respectively， and were stable in serum. In vitro cytotoxicity results showed that T7/cRGD-ELE/CTX@CLIP had higher cytotoxicity to glioma cells than single-targeted liposomes or dual-targeted non-cationic liposomes. T7/crGD-ELE/CTX@CLIP affected the apoptosis and cycle of glioma cells， the results showed that ELE/CTX combined with liposomes could more effectively activate the apoptosis channel and inhibit the proliferation of glioma cells， and the use of T7/cRGD short peptide and cation modification enhanced the ability of apoptosis induction. ELE/CTX could effectively block glioma cell cycle at G₂/M phase， and the effect was enhanced after T7/cRGD targeted modification. ConclusionELE can enhance the anti-glioma effect of CTX. The preparation parameters of ELE/CTX@LIP are stable and feasible. Combined with the in vitro efficacy test， the anti-glioma mechanism of T7/cRGD-ELE/CTX@CLIP is preliminarily revealed.

Objective:Diabetic retinopathy (DR) is the most common cause of adult blindness in China. Screening of DR is important for early detection, prevention, and treatment. However, there is still controversy in the research on the prevalence and risk factors of DR in China. This study was designed to evaluate the prevalence of DR and related risk factors in patients with type 2 diabetes mellitus in Beijing City.Methods:A cross-sectional survey was conducted in in Dongcheng District and Tongzhou District, Beijing City. Patients with type 2 diabetes aged 18-80 years were selected from four communities, and all subjects underwent questionnaires, physical examinations, laboratory examinations and fundus photography. The logistic regression model was used to analyze the associated factors of DR.Results:A total of 1 531 subjects were included, with the median age of 66 years old and the average age of (65.6±7.4) years old, and the glycosylated hemoglobin level in the subjects was 7.2%±1.3%, and the glycosylated hemoglobin compliance rate was 56.0%(857/1 531). A total of 254 patients with diabetic retinopathy were detected, and the prevalence of DR was 16.6%(254/1 531). Among them, there were 218 cases of non-proliferative diabetic retinopathy and 36 cases of proliferative diabetic retinopathy. Compared with the non-DR group, there were statistically significant differences in fasting blood glucose ( Z=-3.74, P<0.001), glycosylated hemoglobin( Z=-10.664, P<0.001), urinary microalbumin excretion rate( Z=-7.767, P<0.001), low-density lipoprotein cholesterol( Z=-2.589, P=0.01), and duration of diabetes( Z=-10.189, P<0.001) between the DR group and the non-DR group. Multivariate regression analysis showed that the duration of diabetes ( OR=1.08, 95% CI: 1.06-1.10, P<0.001), glycosylated hemoglobin ( OR=1.38, 95% CI: 1.23-1.55, P<0.001), and FPG ( OR=1.11, 95% CI: 1.03-1.19, P=0.008) were associated factors for DR. Conclusion:In this study, the prevalence of DR in 4 communities of type 2 diabetes in Beijing City was 16.6%. Besides, this study further confirmed that the duration of diabetes, fasting blood glucose levels, and glycosylated hemoglobin are associated factors for DR in patients with type 2 diabetes.

Objective:To compare the efficacy and prognostic evaluation of response evaluation criteria in lymphoma (RECIL) and Lugano classification in patients with 18F-FDG-avid Hodgkin′s lymphoma (HL) and non-HL (NHL) during mid-chemotherapy. Methods:From January 2015 to August 2021, 240 patients (149 males and 91 females, age 50.0(32.0, 62.0) years) with pathologically confirmed lymphoma in Shanxi Cancer Hospital were retrospectively analyzed. Pre-treatment and mid-treatment 18F-FDG PET/CT examinations were performed, and the differences of PET/CT imaging results among patients with different types of lymphoma were analyzed ( χ2 test or Kruskal-Wallis rank sum test). Efficacy evaluation was conducted during mid-chemotherapy, and the results were divided into complete remission (CR), partial remission (PR), stable disease (SD), progressive disease (PD) according to Lugano classification, which were divided into CR, PR, mild remission (MiR), SD, PD according to RECIL. For the better comparison with Lugano classification, MiR was included in PR group (recorded as RECIL-1) and SD group (recorded as RECIL-2) in this study. All patients were followed up, and the progression free survival (PFS) was analyzed. Kappa test, χ2 test or Fisher exact probability method were used to analyze the data, and ROC curve was used to compare the prediction efficiency of different standards. Results:Among 240 patients with different types of lymphoma (96 HL, 30 follicular lymphoma (FL), 114 diffuse large B-cell lymphoma (DLBCL)), there were statistically significant differences in baseline SUV max ( H=54.96, P<0.001) and the sum of longest diameters ( H=15.85, P<0.001). Patients were followed up for 12-89 months, and 26 patients (10.8%) were evaluated as MiR according to the RECIL. The consistency ( Kappa) was 0.84 between results of RECIL-1 and Lugano classification, which was 0.74 between RECIL-2 and Lugano classification (both P<0.001). According to Lugano classification, the PFS rates of patients evaluated as CR, PR, SD and PD were 91.4%(148/162), 57.1%(36/63), 1/3 and 3/12 respectively, which were 91.3%(136/149), 62.8%(49/78), 1/2 and 2/11 for RECIL-1, and 91.3%(136/149), 57.7%(30/52), 71.4%(20/28) and 2/11 for RECIL-2 respectively ( χ2 values: 46.64-52.44, all P<0.001). The AUC of Lugano classification for predicting PFS had a trend to be higher than AUCs of RECIL-1 and RECIL-2 (0.774, 0.758 and 0.746; z values: 1.28, 1.61, P values: 0.200, 0.107). Conclusion:RECIL and Lugano classification have similar efficacy and prognostic evaluation effect on patients with 18F-FDG-avid HL and NHL during mid-chemotherapy.

Objective:To compare the value of 3 methods (threshold method, visual method and CT method) based on 18F-FDG PET-CT for qualitative diagnosis of solitary pulmonary nodules (SPN). Methods:The clinical characteristics, pathological results, CT signs and maximum standardized uptake value (SUV max) of 226 SPN patients who underwent 18F-FDG PET-CT and met lung imaging reporting and data system (Lung-RADS1.1) grading criteria grade 2-4 in Shanxi Province Cancer Hospital from January 2015 to January 2019 were retrospectively analyzed, and the diagnostic efficacy of threshold method (according to SUV max), visual method [according to the degree of fluorodeoxyglucose (FDG) uptake in the mediastinum or liver blood pool] and CT method (according to Lung-RADS1.1 grading criteria) for SPN were compared by using receiver operating characteristic (ROC) curve. The highest diagnostic accuracy of CT method and the highest diagnostic accuracy of threshold method and visual method were combined as PET-CT comprehensive diagnosis method, and the diagnostic efficiency of which was compared with the other methods. Results:Among the 226 patients with SPN, 174 cases were malignant and 52 cases were benign in pathology. ROC curve analysis showed that the area under the curve (AUC) of CT method 2 (defined Lung-RADS1.1 grade 4A and below as benign, grade 4B and above as malignant) in CT methods for qualitative diagnosis of SPN was 0.622, the sensitivity was 87.93%, and the accuracy was 76.11%, the diagnostic efficiency was higher than method 2. The AUC of the threshold method 1 (defined solid nodules that SUV max≥2.5 and ground-glass nodules that SUV max≥1.14 as malignant, the others as benign) in threshold methods for qualitative diagnosis of SPN was 0.675, the sensitivity was 85.06%, and the accuracy was 76.99%, the diagnostic efficiency was higher than other methods in the threshold methods and visual methods. The AUC of PET-CT comprehensive diagnosis method (combination of CT method 2 and threshold method 1) for qualitative diagnosis of SPN was 0.652, the sensitivity was 97.70%, and the accuracy was 82.74%, the diagnostic efficiency was higher than other methods. Conclusions:There is no significant difference among threshold method, visual method and CT method based on 18F-FDG PET-CT in qualitative diagnosis of SPN. The diagnostic efficiency of combining CT method with threshold method is significantly improved.

Objective:To evaluate the value of 18F-FDG uptake features in differential diagnosis of benign and malignant solitary pulmonary lesions. Methods:A total of 274 patients (181 males, 93 females, age: (61.0±10.2) years) with solitary pulmonary lesions who underwent 18F-FDG PET/CT between September 2010 and March 2017 were retrospectively analyzed. The 18F-FDG uptake features of lesions were divided into 5 types: full uptake (Group A), circular uptake (Group B), multi-focus uptake (Group C), mild uptake (Group D) and no-uptake (Group E). According to the pathology or follow-up results, the incidences of benign and malignant lesions in each group were analyzed. The diagnostic efficiencies of 18F-FDG uptake feature classification(A+ B=malignancy, C+ D+ E=benign) and SUV method (lesions with SUV max≥2.5 was taken as the malignancy) were calculated. χ2 test and ROC curve were used to analyze the data. Results:The malignant incidences of Groups A-E were 86.25%(138/160), 71.05%(27/38), 31.25%(10/32), 43.48%(10/23) and 14.29%(3/21), respectively ( χ2=79.49, P<0.001), and the rate of Group A was the highest ( χ2 values: 5.11-55.84, all P<0.05). There were significant differences in the malignancy incidence between A+ B group and C+ D+ E group (83.33%(165/198) vs 30.26%(23/76)), and between SUV max≥2.5 group and SUV max<2.5 group (76.09%(175/230) vs 29.55%(13/44); χ2 values: 71.83 and 37.15, both P<0.001). The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of the 18F-FDG uptake feature classification and the SUV method were 87.77%(165/188) vs 93.09%(175/188), 61.63%(53/86) vs 36.05%(31/86), 79.56%(218/274) vs 75.18%(206/274), 83.33%(165/198) vs 76.09%(175/230), 69.74%(53/76) vs 70.45%(31/44), respectively. ROC curve analysis showed that the diagnostic accuracy of the 18F-FDG uptake feature classification was higher than that of SUV method (AUCs: 0.747, 0.646; Z=4.05, P<0.001). Conclusions:18F-FDG uptake feature classification can improve the diagnostic specificity and accuracy of solitary pulmonary lesions. The multi-focus uptake feature maybe a sign of benign lesions, which still needs more researches to confirm.
