Objective To compare the efficacy and toxicity of paclitaxel and carboplatin regimen concurrent chemoradiotherapy and radiotherapy alone in the treatment of stage Ⅲ cervical cancer.Methods A retrospective analysis of 158 patients with stage Ⅲ cervical cancer who were admitted to Shanxi Provincial Cancer Hospital from May 2009 to October 2012 was conducted.According to different treatment methods,86 patients were in the concurrent chemoradiotherapy group and 72 patients were in the radiotherapy group.The efficacy and adverse reactions of the two groups were compared.Results The effective rate (complete remission + partial remission) in the concurrent radiotherapy group and radiotherapy group was 95.3％ (82/86) and 84.7 ％ (61/72),respectively,and the difference was statistically significant (x2 =5.15,P =0.023).The 1-,2-,3-,and 5-year survival rates of the concurrent radiotherapy group and radiotherapy group were 93.0 ％ (80/86),77.9 ％ (67/86),68.6 ％ (59/86),60.5 ％ (52/86),and 81.9 ％ (59/72),61.1％ (44/72),41.7 ％ (30/72),36.1％ (26/72),respectively,and the differences were statistically significant (x2 values were 4.55,5.29,11.56,9.30,all P ＜ 0.05).The short-term adverse reactions in the concurrent chemoradiotherapy group and radiotherapy group were mainly myelosuppression and gastrointestinal reactions,and the incidence of myelosuppression was 87.2 ％ (75/86) and 50.0 ％ (36/72),respectively,and the difference was statistically significant (x2 =25.96,P ＜ 0.01);the incidence of gastrointestinal reactions was 91.9 ％ (79/86) and 20.8 ％ (15/72),respectively,and the difference was statistically significant (x2 =82.04,P ＜ 0.01).The incidence of radiation proctitis in the concurrent radiotherapy and chemotherapy group was 17.4 ％ (15/86) and 16.7 ％ (12/72),respectively,and the difference was not statistically significant (x2 =0.017,P =0.89);the incidence of radiation cystitis was 7.0 ％ (6/86) and 5.6 ％ (4/72),respectively,and the difference was not statistically significant (x2 =0.134,P =0.71).Conclusion Paclitaxel and carboplatin regimen chemotherapy combined with radiotherapy can improve the survival rate of patients with stage Ⅲ cervical cancer,and the adverse reactions are tolerable.

Objective:To investigate the relationship between tumor volume changes, squamous cell carcinoma antigen (SCC-Ag), carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125) and the prognosis of cervical cancer patients with concurrent radiotherapy and chemotherapy and their combined prediction of prognosis.Methods:One hundred and twenty-eight patients in Shanxi Cancer Hospital from February 2018 to February 2020, with cervical cancer undergoing radical concurrent radiotherapy and chemotherapy were selected for a prospective study. According to different prognostic effects, the patients were divided into poor prognosis group (44 cases) and good prognosis group (84 cases). The general data, tumor reduction rate (TVRR), SCC-Ag, CEA, and CA125 levels were compared between the two groups, and the Logistic regression equation was used to analyze the prognostic factors of patients with concurrent radiotherapy and chemotherapy for cervical cancer. The receiver operating characteristic (ROC) curve and the area under the curve (AUC) were used to analyze the performance of each index and the joint prediction of prognosis. Kaplan-Meier survival curve analysis and log-rank (Mantel-Cox) were used to test the survival curves of TVRR, SCC-Ag, CEA, CA125 high-risk individuals and low-risk individuals.Results:The TVRR in the poor prognosis group was significantly lower than that in the good prognosis group: (76.63 ± 7.52)% vs. (85.54 ± 6.71)%, the SCC-Ag, CEA, CA125 were significantly higher than those in the good prognosis group: (6.98 ± 2.15) μg/L vs. (4.61 ± 1.37) μg/L, (9.34 ± 2.23) μg/L vs. (5.76 ± 1.87) μg/L, (68.79 ± 12.01) kU/L vs. (49.97 ± 15.22) kU/L, and there were statistical differences ( P<0.05). Logistic regression showed that TVRR, SCC-Ag, CEA and CA125 were significant factors influencing the prognosis of patients with concurrent chemoradiotherapy for cervical cancer ( P<0.05). Among the single indicators, TVRR predicted the highest prognosis AUC, and the combined prognostic AUC of all indicators (0.837, 95% CI 0.761 to 0.920) was higher than any single indicator, with a sensitivity of 81.82% and specificity of 84.52%. The survival curves of TVRR, SCC-Ag, CEA, CA125 between high-risk and low-risk patients showed statistically significant differences ( P<0.05). Conclusions:The changes in tumor volume, SCC-Ag, CEA, CA125 and the prognosis of patients with concurrent radiotherapy and chemotherapy for cervical cancer have a certain correlation. The combined examination of the four in the early stage is expected to become a new approach to clinically predict the prognosis of cervical cancer and make appropriate treatment plans.

When partial nephrectomy is performed by posterior abdominal approach, the surgical field is poorly exposed, resulting in increased surgical difficulty and risk of injury.In this study, 28 patients with T 1a stage kidney tumors underwent retroperitoneal laparoscopic partial nephrectomy. Intraoperatively, exposure of the surgical field was achieved using the percutaneous puncture of the renal fascia suspension technique. There were no dissatisfactory exposures due to peritoneal damage during the surgery, no additional tubes were inserted, and no conversions to open surgery were needed. The operation time was (76.5±20.3) minutes, blood loss was (92.1±18.7) ml, renal artery clamping time was (19.5±4.3) minutes. Postoperatively, there were no complications such as bleeding, infection, or hematuria.

Background Paraquat (PQ) is one of the environmental factors that can cause sporadic Parkinson's disease (PD). Microglia-mediated neuroinflammation plays an important role in the occurrence and development of PD. Our previous studies have found that low doses of PQ can activate BV-2 microglia to the M1 phenotype and exert pro-inflammatory effects, but the associated mechanism is not clear yet. Objective To explore the role of c-Jun N-terminal kinase (JNK)/activator protein 1 (AP-1) signaling pathway in PQ-induced activation of the NOD-like receptor thermal protein domain associated protoin 3 (NLRP3) inflammasome in microglia. Methods An in vitro microglia model was established. The cells were treated with 0, 0.03, 0.06,and 0.12 μmol·L⁻¹ PQ for 24 h, the whole cell protein was extracted. The relative expression levels of JNK, AP-1 constituent proteins (c-Jun, c-Fos), NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), caspasse-1 precursor (pro caspase-1), interleukin-18 (IL-18), and interleukin-1β (IL-1β) were evaluated by Western blotting, to observe the effects of PQ exposure on JNK/AP-1 signaling pathway and NLRP3 inflammasome. After the treatment of 20 μmol·L⁻¹ JNK inhibitor SP600125, the above proteins were detected again, to explore the driving effect of JNK/AP-1 signaling pathway on NLRP3 inflammasome activation. Results After PQ exposure, the relative expression levels of key proteins of JNK, c-Jun, and c-Fos, NLRP3, ASC, and pro caspase-1 in the 0.06 μmol·L⁻¹ PQ group and the 0.12 μmol·L⁻¹ PQ group were higher than those in the 0 μmol·L⁻¹ PQ group (P＜0.05), and the relative expression levels of IL-18 and IL-1β increased with higher exposure (P＜0.05). After the treatment of JNK inhibitor SP600125, the relative expression levels of key proteins of JNK/AP-1 signaling pathway (JNK, c-Jun, and c-Fos), NLRP3 inflammasome (NLRP3, ASC, and Pro caspase-1), and inflammatory factors (IL-18 and IL-1β) in the control group, the 20 μmol·L⁻¹ SP600125 group, and the 20 μmol·L⁻¹ SP600125+0.06 μmol·L⁻¹ PQ group were lower than those in the 0.06 μmol·L⁻¹ PQ group (P＜0.05). Conclusion PQ exposure can activate the JNK/AP-1 signaling pathway and subsequently drive the activation of NLRP3 inflammasome in BV-2 microglia to mediate neuroinflammatory responses..
