Objective To investigate the probability and dosimetric risk factors of lung injury after sequential immune checkpoint inhibitors (ICIs) and thoracic radiotherapy. Methods A retrospective analysis was conducted on 139 patients who received sequential ICIs and thoracic radiotherapy in Xuzhou Cancer Hospital and Affiliated Hospital of Xuzhou Medical University between February 2020 and February 2024. The relationships of clinical factors and lung and heart volume dose parameters with grade ≥ 2 acute lung injury (ALI) in patients with thoracic tumors were studied using univariable (χ² test, t test, nonparametric test) and multivariable (binary logistic regression analysis) methods. The thresholds of dosimetric risk factors were determined using the receiver operating characteristic curves. Clinical factors included age, gender, smoking history, type of ICIs, cycle of ICI application, and the interval between ICI application and thoracic radiotherapy. Dose parameters included total radiotherapy dose, single dose, planning target volume, maximum dose of planning target volume, average dose of planning target volume, total lung volume, heart volume, and the V₅, V₁₀, V₁₅, V₂₀, V₂₅, V₃₀, V₃₅, and V₄₀ of lung and heart. Results The incidence of grade ≥ 2 ALI in the included cases was 36% (50/139). The χ² test did not find any statistically significant clinical factors. In the univariable and binary Logistic regression analysis, lung V₁₅ and V₂₀, heart V₁₅ and V₂₀, and lung volume were independent risk factors for the occurrence of grade ≥ 2 ALI in sequential ICIs and thoracic radiotherapy. The thresholds were 18.51% for lung V₁₅, 14.43% for lung V₂₀, 32.41% for heart V₁₅, and 17.74% for heart V₂₀. Conclusion For patients who are going to receive thoracic radiotherapy after ICIs, the thresholds of lung V₁₅ and V₂₀ and heart V₁₅ and V₂₀ in the radiotherapy plan are recommended to be less than 18.51%, 14.43%, 32.41%, and 17.74%, respectively, which can effectively reduce the occurrence of grade ≥ 2 ALI.

Chronic prostatitis is a common and frequently occurring disease in male clinics. Due to the diverse symptoms， complex etiology， unclear mechanisms， and recurrent episodes of chronic prostatitis， Western medicine often faces the challenge of limited treatment options and unsatisfactory outcomes. In order to fully leverage the unique advantages of traditional Chinese medicine （TCM） in the treatment of chronic prostatitis， the China Association of Chinese Medicine organized a discussion among experts from the fields of TCM urology， Western urology， and related pharmacy. The experts focused on the advancements in the understanding of chronic prostatitis in modern medicine， various theories on the etiology， pathogenesis， and treatment of chronic prostatitis in TCM， entry points from interdisciplinary fields， the role and advantages of TCM in the comprehensive management of chronic prostatitis， and research into mechanisms related to chronic prostatitis. After discussions， the experts concluded that chronic prostatitis is one of the diseases where TCM has a distinct advantage. TCM can effectively improve the clinical syndromes of chronic prostatitis， including urinary issues， social psychology， organ specificity， infection， nervous system problems， pain and discomfort， sexual dysfunction， etc.， and can enhance the quality of life. For patients with chronic prostatitis who cannot tolerate or may not accept the adverse effects of Western medicine， as well as for those with non-inflammatory chronic prostatitis/chronic pelvic pain syndrome （CP/CPPS）， those with pain as the primary symptom， those with urinary tract symptoms， those with coexisting anxiety and depression， and those with abnormal semen liquefaction， TCM-based treatment can be the main approach. Currently， the optimal diagnosis and treatment strategy for chronic prostatitis has not yet been established， and further research from perspectives such as clinical epidemiology， evidence-based medicine， and molecular biology is needed. Both TCM and Western medicine should integrate their respective strengths， clarify the role and advantages of TCM interventions based on mutual reference， and improve the diagnosis and treatment standards for chronic prostatitis in China.

Objective To observe the effects of Tianma Gouteng Decoction combined with magnesium sulfate and Labetalol on lowering blood pressure and improving hemorheology in patients with gestational hypertension.Methods Ninety patients with gestational hypertension of liver-yang hyperactivity type were randomly divided into the combination group and the control group,with 45 cases in each group.The control group was treated with magnesium sulfate combined with Labetalol,and the combination group was treated with Tianma Gouteng Decoction on the basis of treatment for the control group.The course of treatment lasted for 5 days.The changes of systolic blood pressure(SBP),diastolic blood pressure(DBP),urinary protein level,and hemorheological indicators of the two groups were observed before and after the treatment.Moreover,the adverse pregnancy outcomes,adverse reactions,and patients'satisfaction of the two groups were compared.Finally,the influencing factors of patients'adverse pregnancy outcomes were investigated by logistic regression analysis.Results(1)After treatment,the SBP,DBP and urinary protein level of patients in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease in the combination group was significantly superior to that in the control group(P＜0.01).(2)After treatment,the hemorheological indicators of plasma viscosity,whole blood viscosity and hematocrit of patients in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease in the combination group was significantly superior to that in the control group(P＜0.05 or P＜0.01).(3)The total incidence of adverse pregnancy outcomes in the combination group was 11.11%(5/45),which was significantly lower and that in the control group(33.33%,15/45),the difference being statistically significant(P＜0.05).(4)The patients'satisfaction of the combination group was 97.78%(44/45),which was significantly higher than that of the control group(84.44%,38/45),and the difference was statistically significant(P＜0.05).(5)The total incidence of adverse reactions in the combination group was 13.33%(6/45)and that in the control group was 8.89%(4/45),but the intergroup comparison showed no significant difference between the two groups(P＞0.05).(6)Logistic regression analysis of influencing factors showed that no medication of Tianma Gouteng Decoction combined with Labetalol and magnesium sulfate,and poor antihypertensive effect were the independent risk factors for adverse pregnancy outcomes in patients with gestational hypertension(all OR＞1,P＜0.05).Conclusion Tianma Gouteng Decoction combined with magnesium sulfate and Labetalol in treating gestational hypertension exerts certain antihypertensive effect,and the therapy can effectively improve the hemorheological indicators and the adverse pregnancy outcomes,and enhance the patients'satisfaction.

Objective To investigate the effect and mechanism of transplantation of neuregulin1(NRG1)gene-modified bone marrow mesenchymal stem cells(BMSCs)on the repair of hemi-transected spinal cord injury(SCI)in rats.Methods Isolated and cultured rat BMSCs,followed by transfection with the NRG1 gene.The levels of NRG1 in BMSCs lysate and culture supernatant was deected by ELISA method,and the proliferation activity of the BMSCs was detected by cell counting method.Forty-three healthy 8-week-old SD rats were randomly divided into control group(n=10),SCI model group(n=10),BMSCs group(n=10),and NRG1-BMSCs group(n=13).After establishing the spinal cord hemisection model,animals received in-situ transplantation of BMSCs or NRG1-BMSCs.On the 1,7,14,21,and 28 days after transplantation,the hind limb motor function was evaluated using BBB score and inclined plate test;on the 7th day after transplantation,the migration and distribution of transplanted cells was monitored using a fluorescence microscope;on the 28th day after transplantation,the pathological changes of rat spinal cord tissues was examined using HE staining and Nissl staining;cell apoptosis using TUNEL staining,and levels of endoplasmic reticulum stress-related proteins[X-box binding protein 1(XBP1),C/EBP homologous protein(CHOP),activating transcription factor 4(ATF4),ATF6,glucose-regulated protein 78(GRP78)]and apoptosis-related proteins[B-cell lymphoma-2(Bcl-2)and Bcl-2-associated protein X(Bax)]in rat spinal cord tissues using Western blotting.Results BMSCs were successfully isolated,cultured,and transfected with the NRG1 gene.ELISA method results showed that the NRG1 contents in the NRG1-BMSCs lysate and culture supernatant were significantly higher than that of BMSCs in a time-dependent manner(P<0.05).The proliferation activity of NRG1-BMSCs was significantly higher than that of BMSCs(P<0.05).On the 21 and 28 days after transplantation,the BBB score and the slope angle of the inclined plate in NRG1-BMSCs group were higher than those in SCI model group or BMSCs group(P<0.05).However,it did not reverse to the level in control group(P<0.05).On the 28th day after transplantation,compared with the SCI model group and BMSCs group,neuronal pyknosis reduced,the Nissl body density increased,the expression levels of XBP1,CHOP,ATF4,ATF6,GRP78,and Bax,and the rate of TUNEL-positive cells significantly reduced in NRG1-BMSCs group(P<0.05),and the expression level of Bcl-2 significantly increased(P<0.05).Conclusion Transplantation of NRG1 gene-modified BMSCs can alleviate SCI and improve the recovery of motor function in rats.The mechanism may be related to promoting the proliferation activity of BMSCs,inhibiting cell apoptosis,and mitigating endoplasmic reticulum stress.

Objective To compare the effects of CalliSpheres drug-eluting beads transcatheter arterial chemoembolization(DEB-TACE)and conventional TACE(c-TACE)on liver fibrosis and liver function in the treatment of primary hepatocellular carcinoma(HCC).Methods A total of 40 patients diagnosed with HCC at Xuzhou Municipal Cancer Hospital of China between October 2020 and October 2022 were enrolled in this study.According to therapeutic scheme,the patients were divided into DEB-TACE group(n=20)and c-TACE group(n=20).The preoperative,and postoperative 5-day and one-month hyaluronidase(HA),type Ⅲ procollagen peptide(P Ⅲ NP),type Ⅳ collagen(CⅣ)and laminin(LN),alanine aminotransferase(ALT),aspartate aminotransferase(AST),total bilirubin(TBil),albumin(Alb),and prothrombin time(PT)were compared between the two groups.Results The technical success rate was 100％in both groups,and tumor staining completely disappeared immediately after TACE in all patients.The postoperative 5-day levels of HA,LN,P Ⅲ NP,and CⅣ in both groups were remarkably higher than the preoperative ones(P＜0.05).One month after TACE,HA level in the DEB-TACE group was prominently higher than its preoperative value(P＜0.05);HA and LN levels in the c-TACE group were obviously higher than their preoperative values(P＜0.05);and the HA and LN levels in c-TACE group were significantly higher than those in DEB-TACE group(P＜0.05).Five days after TACE,in the DEB-TACE group the AST and PT levels were higher than their preoperative values while the Alb level was lower than its preoperative value(P＜0.05);in the c-TACE group the ALT,AST,TBiL and PT were higher than their preoperative values while the Alb level was lower than its preoperative value(P＜0.05);the ALT and AST levels in the c-TACE group were strikingly higher than those in the DEB-TACE group while Alb level was strikingly lower than that in the DEB-TACE group(P＜0.05).Conclusion Both CalliSpheres DEB-TACE and c-TACE can aggravate liver fibrosis and cause liver function damage.However,the degree of liver fibrosis and liver function damage caused by CalliSpheres DEB-TACE is less than that caused by c-TACE.(J Intervent Radiol,2024,33:259-263)

Objective:To explore the mechanism by which miRNA-4469 (miR-4469) regulates the proliferation and invasion of renal cancer cells in vitro.Methods:The survival differences of patients with different expression levels of miR-4469 were analyzed based on the OncomiR database. Real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) method was used to detect the expression of miR-4469 in renal cancer cell lines ACHN, OS-RC-2, SK-RC-20, 769-P, A498 and normal renal tubular epithelial cell line HK-2, and the renal cancer cells with the lowest expression level of miR-4469 were divided into miR-4469 group and control group, and were transfected with miR-4469 mimic and negative control sequence, respectively. The CCK-8 assay was used to detect the cell proliferation ability (expressed as absorbance value) in the two groups, and Transwell assay was used to analyze the number of invasive cells in the two groups. TargetScan Release 8.0 software was used to predict the binding site between miR-4469 and protein disulfide isomerase A4 (PDIA4) mRNA, and dual-luciferase reporter gene assay was used to verify the targeting relationship between miR-4469 and PDIA4 mRNA. qRT-PCR method was used to detect the expression of PDIA4 mRNA in cells of each group, and Western blotting method was used to detect the expression levels of PDIA4 protein and PI3K-AKT-m-TOR pathway proteins in cells of each group.Results:Analysis of relevant data from the OncomiR database showed that compared with patients with low miR-4469 expression, the overall survival of renal cancer patients with high miR-4469 expression was better ( P < 0.001). The relative expression of miR-4469 in each renal cancer cell line was lower than that in HK-2 cells (all P < 0.05), and the expression of miR-4469 in 769-P cells was the lowest, which were selected to perform the subsequent experiments. The proliferation ability of 769-P cells in the miR-4469 group was lower than that in the control group ( P < 0.01). The number of 769-P cell invasions in the miR-4469 group were less than that in the control group [(19±3) cells vs. (64±7) cells, t = 5.44, P = 0.002]. Compared with the co-transfection of wild-type PDIA4 and miR-4469 negative sequence group, the relative luciferase activity of cells in the co-transfection of wild-type PDIA4 and miR-4469 mimic sequence group was lower (0.42±0.07 vs. 1.01±0.08, t = 5.74, P = 0.001); there was no statistical difference in cell luciferase activity between the co-transfected mutant PDIA4 and miR-4469 negative sequence group and the co-transfected mutant PDIA4 and miR-4469 mimic sequence group (0.99±0.11 vs. 1.02±0.11, t = 0.19, P = 0.001). The relative expression levels of PDIA4 mRNA in 769-P cells in the miR-4469 group were lower than that in the control group (0.98±0.23 vs. 7.19±2.23, t = 2.77, P = 0.032). Compared with the control group, the expression of PDIA4 protein and PI3K-AKT-m-TOR pathway-related p-PI3K, p-AKT, p-mTOR, and p-SGK1 proteins in 769-P cells in the miR-4469 group were all lower (all P < 0.05). Conclusions:miR-4469 may be related to the survival of renal cancer patients, and its expression is down-regulated in various renal cancer cell lines. miR-4469 may inhibit the proliferation and invasion of renal cancer 769-P cells by regulating the PI3K-AKT-m-TOR pathway through PDIA4.

Objective:To verify the predictive value of the Second Revision of the International Staging System (R2-ISS) in newly diagnosed patients with multiple myeloma (MM) who underwent first-line autologous hematopoietic stem cell transplantation (ASCT) in a new drug era in China.Methods:This multicenter retrospective cohort study enrolled patients with newly diagnosed MM from three centers in China (Beijing Chao-Yang Hospital, Capital Medical University; the First Affiliated Hospital, Sun Yat-Sen University, and the Second Affiliated Hospital of Naval Medical University) from June 2008 to June 2018. A total of 401 newly diagnosed patients with MM who were candidates for ASCT were enrolled in this cohort, all received proteasome inhibitor and/or immunomodulator-based induction chemotherapy followed by ASCT. Baseline and follow-up data were collected. The patients were regrouped using R2-ISS. Progression-free survival (PFS) and overall survival (OS) were analyzed. The Kaplan-Meier method was used to analyze the survival curve and two survival curves were compared using the log-rank test. Cox regression analysis were performed to analyze the relationship between risk factors and survival.Results:The median age of the patients was 53 years (range 25-69 years) and 59.5% (240 cases) were men. Newly diagnosed patients with renal impairment accounted for 11.5% (46 cases). According to Revised-International Staging System (R-ISS), 74 patients (18.5 %) were diagnosed with stage Ⅰ, 259 patients (64.6%) with stage Ⅱ, and 68 patients (17.0%) with stage Ⅲ. According to the R2-ISS, the distribution of patients in each group was as follows: 50 patients (12.5%) in stage Ⅰ, 95 patients (23.7%) in stage Ⅱ, 206 patients (51.4%) in stage Ⅲ, and 50 patients (12.5%) in stage Ⅳ. The median follow-up time was 35.9 months (range, 6-119 months). According to the R2-ISS stage, the median PFS in each group was: 75.3 months for stage Ⅰ; 62.0 months for stage Ⅱ, 39.2 months for stage Ⅲ, and 30.3 months for stage Ⅳ; and the median OS was not reached, 86.6 months, 71.6 months, and 38.5 months, respectively. There were statistically significant differences in PFS and OS between different groups (both P<0.001). Multivariate Cox regression analysis showed that stages Ⅲ and Ⅳ of the R2-ISS were independent prognostic factors for PFS ( HR=2.37, 95% CI 1.30-4.30; HR=4.50, 95% CI 2.35-9.01) and OS ( HR=4.20, 95% CI 1.50-11.80; HR=9.53, 95% CI 3.21-28.29). Conclusions:The R2-ISS has significant predictive value for PFS and OS for transplant-eligible patients with MM in the new drug era. However, the universality of the R2-ISS still needs to be further verified in different populations.
