RESUMO
For a long time, macrolides have been the first choice for the antibacterial treatment for pertussis.However, in the past decade, resistance to macrolide antimicrobials has been common in clinically isolated Bordetella pertussis in China, which is in contradiction with the recommended macrolide treatment.Therefore, Trimethoprim-Sulfamethoxazole (TMP-SMZ) is suggested as the first choice for antibacterial treatment for pertussis in China, with a dosage determined according to age and body weight, lasting 14 days.If TMP-SMZ cannot be used, full-dose and full-course β-lactam antimicrobials may be used, of which the effects should be assessed carefully.The impact of other antibacterial drugs, such as quinolones and tetracyclines, on the elimination of Bordetella pertussis should also be evaluated as soon as possible to treat adult pertussis and potential cases caused by drug-resistant bacteria in future.
RESUMO
Objective:To study the effects of poly adenosine diphosphate ribose polymerase (PARP) inhibitors niraparib and pamiparib on the radiosensitivity of breast cancer cell lines MCF-7 and MDA-MB-436, and to explore its mechanism.Methods:MCF-7 and MDA-MB-436 cells were divided into control group, niraparib group, pamiparib group, radiation group, combination group treated with niraparib and radiation, and combination group treated with pamiparib and radiation, respectively. The effects of drugs on cell proliferation and radiosensitivity were measured by CCK-8 assay and colony formation assay, respectively. The effect of drugs combined with radiation on cell cycle and apoptosis were detected by flow cytometry. Immunofluorescence method was used to detect the changes of γ-H2AX focal number of cells. The expressions of FANCG, Bax and Bcl-2 mRNA and protein were detected by qPCR and Western blot, respectively.Results:Both niraparib and pamiparib inhibited the proliferation of breast cancer cells MCF-7 and MDA-MB-436 in a time-dose dependent manner. With the increase of irradiation dose, D0, Dq, SF2 value of MCF-7 and MDA-MB-436 cells decreased, and SER D0 and SER Dq value increased. Compared with control group, the percentages of cells in G 2/M phase were increased ( tMCF-7=41.66, 44.08, P<0.05; t436=24.69, 18.91, P<0.05), the percentage of cells in G 0/G 1 phase were decreased ( tMCF-7=8.67, 29.61, P<0.05; t436=26.39, 29.12, P<0.05), and the cell apoptosis rate was significantly increased ( tMCF-7=11.17, 11.71, P<0.05; t436=42.68, 15.89, P<0.05) in the combination group. Compared with control group, the number of γ-H2AX foci of MCF-7 cells in the radiation group and combination group treated with niraparib and radiation increased significantly at 2 h after irradiation ( t=8.89, 21.72, P<0.05). At 24 h after irradiation, the number of γ-H2AX foci basically returned to normal level in the radiation group but remained at a higher level in the combination group ( t=8.82, P<0.05). Compared with control group, the expressions of FANCG and Bcl-2 mRNA decreased ( tFANCG=14.07, P<0.05; tBcl-2=29.21, P<0.05), the expression of Bax mRNA increased ( t=8.90, P<0.05), and the expression of FANCG and Bcl-2 proteins decreased ( tFANCG=7.09, P<0.05; tBcl-2=10.24, P<0.05), while the expression of Bax protein increased ( t=2.90, P<0.05) in the combination group. Conclusions:PARP inhibitors niraparib and pamiparib can increase the radiosensitivity of breast cancer MCF-7 and MDA-MB-436 cells probably through down-regulating the expression of FANCG in FA-BRCA pathway, up-regulating apoptosis-related genes and inhibiting DNA damage repair.
RESUMO
Objective:To evaluate the effectiveness and safety of concurrent chemoradiotherapy combined with nimotuzumab in the treatment of patients with inoperable esophageal squamous cell carcinoma (ESCC).Methods:A retrospective analysis was conducted on the clinical data of 503 patients with inoperable ESCC who underwent concurrent chemoradiotherapy in the Department of Radiation Oncology, Changzhou No. 2 People′s Hospital Affiliated to Nanjing Medical University and Department of Radiation Oncology, Affiliated Hospital of Jiangnan University from 2014 to 2020. Among these patients, 69 received concurrent chemoradiotherapy combined with nimotuzumab (the combined therapy group) and 434 received concurrent chemoradiotherapy alone (the concurrent chemoradiotherapy group). Patients of both groups were matched at a ratio of 1∶2 using the propensity score matching (PSM) method. As a result, 168 patients were determined for clinical analysis, including 61 in the combined therapy group and 107 in the concurrent chemoradiotherapy group. The short-term efficacy and adverse reactions of both groups were compared. The overall survival (OS) curves and progression-free survival (PFS) curves were plotted using the Kaplan-Meier method for the Log-rank test.Results:The two groups showed no statistical difference ( P > 0.05) in clinical baseline characteristics after the PSM. The objective response rate (ORR) of the combined therapy group was significantly higher than that of the concurrent chemoradiotherapy group with statistically significant differences (85.2% vs. 71.0%, χ2 = 4.33, P = 0.037). There was no statistical difference (98.4% vs. 91.6%, P > 0.05) in the disease control rate (DCR) between the two groups. The combined therapy group had median PFS of 28.07 months and 1-, 3-, and 5-year PFS ratios of 78.2%, 37.5% and 29.1%, respectively. The concurrent chemoradiotherapy group had mPFS of 19.54 months and 1-, 3-, and 5-year PFS ratios of 72.9%, 28.3% and 21.3%, respectively. Both groups showed statistically significant differences in PFS ( χ2 = 4.49, P = 0.034). The combined group had median OS of 34.93 months and 1-, 3-, and 5-year OS ratios of 88.5%, 46.8% and 37.4%, respectively. The concurrent chemoradiotherapy group had mOS of 24.30 months and 1-, 3-, and 5-year OS ratios of 81.3%, 35.2% and 28.0%, respectively. Both groups showed statistically significant differences in OS (χ 2= 5.11, P = 0.024), but did not show statistical differences ( P > 0.05) in the severity degree of each adverse effect during the treatment. Conclusions:Concurrent chemoradiotherapy combined with nimotuzumab can improve the ORR and prolong the PFS and OS of patients with inoperable ESCC compared with concurrent chemoradiotherapy alone. Furthermore, combining with nimotuzumab does not increase adverse effects and can be tolerated by patients with high safety.

RESUMO
Objective@#To investigate the adverse events and efficacy in cervical cancer patients receiving intensity modulated radiationtherapy (IMRT) plusbrachytherapy with or without chemotherapy, and to indentify the factors that may affect the prognosis.@*Methods@#In this retrospective analysis, we analyzed the clinical and follow-up data of the 422 cervical cancer patients, who received IMRT plus brachytherapy with or without chemotherapy.Among these patients, 353 cases received concurrent chemoradiotherapy and the other 69 cases received radiotherapy alone. Kaplan-Meier method was utilized to calculate the overall survival (OS) rates. Log-rank-test and Cox regression were performed to executing the univariate and multivariate analysis of the OS, respectively.@*Results@#The rate of complete response (CR) in the patients receiving concurrent chemoradiotherapy was significantly higher than that of the patients who received single radiotherapy (77.6% vs. 65.2%, χ2=4.812, P<0.05). The 1-, 3-, and 5-year OS rates were 93.4%, 79.4%, and 65.0%, respectively. Univariate analysis showed that age, Federation International of Gynecology and Obstetr(FIGO)2009 staging, lymph node metastasis, pathological type, chemotherapy experiences concurrent with radiotherapy, short-term efficiency, and sequential chemotherapy could affect the OS (χ2=6.375-613.123, P<0.05). Multivariate analysis showed that FIGO staging, lymph node metastasis, pathological type, chemotherapy experiences concurrent with radiotherapy, and the short-term efficacy were the independent determinants for the prognosis (χ2=3.930-42.994, P<0.05). For patients with positive pelvic lymph node, there were no statistical differences in the para-aortic lymph node (PALN) metastasis whether undergoing prophylactic extended field irradiation of the PALN or not(PALN metastasis rates: 6.1% vs. 16.8%, P>0.05). The OS for the patients receiving prophylactic extended field irradiation of the PALN was higher than that of patients without prophylactic radiation (χ2=3.953, P<0.05).@*Conclusions@#Cervical cancer patients receiving IMRT plus brachytherapy with or without chemotherapy had achieved promising prognosis. Prophylactic extended field irradiation of the PALN contributed to the improved OS in the patients with pelvic lymph node metastasis. FIGO staging, pathology type, lymph node metastasis, radiotherapy concurrent with chemotherapy or not, and short-term efficiency were independent factors for the prognosis.

RESUMO
Objective To assess the long-term efficacy and adverse effects of three-dimensional radiotherapy (3-DCRT) for elderly patients with esophageal cancer,to investigate the effects of diabetes and hypertension on radiation esophagitis and pneumonitis and to analyze the prognostic factors.Methods A total of 233 patients aged 70 or over with esophageal squamous cell carcinoma were treated with 3-DCRT,and 27 of the patients had type-2 diabetes and 63 had hypertension.Radiation esophagitis and pneumonitis were monitored in patients with or without diabetes and in patients with or without hypertension.Potential prognostic factors were analyzed by Logrank single factor analysis and Cox multivariate analysis.Results The incidences of radiation esophagitis and pneumonitis in grade 3 or over were significantly higher in patients with diabetes than in those without diabetes (Z =-3.762,-2.972;P <0.001,0.003).The incidences of radiation esophagitis and pneumonitis in grade 3 or over in patients with hypertension were significantly higher than in those without hypertension (Z =-2.610,-2.209;P =0.009,0.027).The 1-,3 and 5-year overall survival (OS) rates were 70.6%,35.8% and 23.9%,respectively.The median OS was 23.0 months (95%CI:18.6-27.5).Univariate analysis showed that age (x2 =4.274,P =0.039),T stage (x2=9.376,P 0.025),N-stage (x2=8.504,P=0.014),TNM stage (x2=7.806,P=0.020),gross tumor volume (GTV) (x2 =5.209,P =0.022) and short-term therapeutic efficacy (x2 =25.276,P<0.001) had influenced OS.Multivariate analysis showed that T-stage (P =0.001),N-stage (P =0.007),TNM stage (P =0.002) and short term therapeutic efficacy (P < 0.001) were independent prognostic factors for OS.Conclusions 3-DCRT achieves favorable long-term efficacy in elderly patients with esophageal cancer.Diabetes and hypertension are potential risk factors for radiation esophagitis and pneumonitis.T-stage,N-stage,TNM stage,and short term therapeutic efficacy are independent prognostic factors.
RESUMO
Objective To study the possible pathogenesis of TNBS (2,4,6-trinitrobenzenesulfonic acid)-induced inflammatory bowel disease (IBD) in a mouse model by analyzing histological changes in colon and the expression of cytokines and transcription factor RORγt related to T cell subsets in mesenteric lymph nodes.Methods Female BALB/c mice aged 6-8 weeks were randomly grouped into two groups: IBD model and normal control groups.The mouse model of IBD was established by treating mice with 200 μl of 5% TNBS/50% ethanol solution (1∶1) through intestinal instillation, while the mice in the normal control group were instilled with PBS.Pathological changes in colon samples of mice were observed.Real-time PCR was performed to detect the dynamic expression of Th1 cytokines (IL-2, IFN-γ and IL-12p40), Th2 cytokine (IL-4), Treg-related cytokine (IL-10), Th17 cell-related cytokines (IL-17, IL-21 and IL-23) and transcription factor RORγt in mesenteric lymph nodes.Results The mice in the model group begun to show abnormal vital signs such as diarrhea, loss of weight and reduced activity, and mild hyperemia of intestinal mucosa and edema from the third day after modeling.Slight lesions were observed in histological slices of colon tissues stained with hematoxylin and eosin (HE).The expression of IL-21, IL-23 and IL-17 at mRNA level were significantly increased, while the expression of other cytokines showed no significant change.On the sixth day after modeling, many pathological symptoms and intestinal mucosal lesions were aggravated, and marked infiltration of inflammatory cells was observed in histological slices of colon tissues, which indicated that the IBD model was successfully induced by TNBS.Compared with the control group, the IBD model group showed significantly enhanced expression of IL-2, IL-12p40 and IL-10 in mesenteric lymph nodes at mRNA level on the sixth day after modeling.Although the expression of IL-21, IL-23, IL-17 and RORγt at mRNA level on the sixth day were down-regulated to different extent as compared with those on the third day, they were still significantly higher than those of the control group.Conclusion Th17 cell-related cytokines play an important role in the early stage of TNBS-induced IBD.With the progression of the disease, both Th1 and Th17 cells are involved in the immunopathological injury of colon tissues.

RESUMO
Objective To optimize the method for radiotherapy target delineation after breast cancer surgery, and to observe its advantage in raising work efficiency. Methods Ten physicians in our department were selected, and 20 patients who received breast?conserving surgery were randomly selected. The 10 physicians delineated the targets for these patients with the method in the control group and the method in the study group, and the time required for each delineation was recorded. The method in the control group was commonly used in daily practice and the method in the study group was optimized. The independent?samples t test was applied to compare the differences between the two groups. Results With the optimized method, the average time of delineation in the study group was less than that in the control group ( 51 min vs. 65 min, P=0. 029) . The time curves for delineation in the control group were relatively flat;the time curves for delineation in the study group were high at first, then decreased gradually, and finally became flat. The time for each physician to finish delineation skillfully was relatively stable, while in the study group, the time started to decrease after delineation for the first few patients, with an apparent learning process. Conclusions The optimized method for target delineation in breast cancer is feasible, reliable, and easy to master, and can increase work efficiency, which is more obvious in physicians with rich experience in delineation.
