Objective To analyze the long?term efficacy of intensity?modulated radiotherapy (IMRT) with or without chemotherapy in treatment of 454 patients with nasopharyngeal carcinoma (NPC) and its influencing factors. Methods A retrospective analysis was performed on the clinical data of 454 patients with non?metastatic NPC who received IMRT with or without chemotherapy in our center from 2007 to 2012. Prescribed doses of 69. 96?73. 92 Gy in 33 fractions, 69. 96 Gy in 33 fractions, 60. 06 Gy in 33 fractions, and 50. 96 Gy in 28 fractions were applied to nasopharyngeal gross tumor volume, cervical metastatic lymph nodes, high?risk drainage area, and low?risk drainage area, respectively. In all patients, 438 received induction chemotherapy, 420 concurrent chemotherapy, and 216 adjuvant chemotherapy, most of which were based on cisplatin and taxol. The Kaplan?Meier method was used for calculating survival rates and the log?rank test was used for survival difference analysis and univariate prognostic analysis. The Cox model was used for the multivariate prognostic analysis. Results The 3?year sample size was 210. The 3?year overall survival ( OS ) , local recurrence?free survival, nodal relapse?free survival, progression?free survival, and distant metastasis?free survival ( DMFS) rates were 88. 1%, 91. 0%, 90. 7%, 80. 5%, and 85. 1%, respectively. Age, T stage, and N stage were influencing factors for the OS rate ( P=0. 011;P=0. 005;P=0. 033);T stage and N stage were influencing factors for the disease progression?free survival ( P=0. 017;P=0. 005) and DMFS ( P=0. 012;P=0. 019) . The grade≥3 acute and late adverse reactions included hematological toxicity , oral mucositis , xerostomia , dysphagia , and brain injury . Conclusions IMRT promotes the long?term survival rates in patients with NPC. The distant metastasis is the major reason for treatment failure. The adverse reactions induced by IMRT combined with chemotherapy are tolerable.

OBJECTIVETo evaluate the immunophenotype conversion of fibroblasts and its clinical significance in the process of breast tumor stromal remodeling.

METHODSCD34, FAP-α, p63 and a-SMA were detected by immunohistochemistry in 273 breast biopsies, including 60 normal breast tissues, 46 atypical ductal hyperplasia (ADH), 60 ductal carcinoma in situ (DCIS), 47 DCIS microinvasive carcinoma (DCIS-MI) and 60 invasive ductal carcinoma (IDC).

RESULTSThe positive expression rates of CD34, FAP-α and α-SMA in the stromal fibroblasts of normal breast tissues were 93.3%, 6.7% and 18.3%, respectively. Those in the stromal fibroblasts of ADH tissues were 95.7%, 4.3% and 10.9%, respectively. Those in the stromal fibroblasts of DCIS tissues were 95.0%, 8.3% and 15.0%, respectively. Those in the IDC tissues were 35.0%, 85.0% and 93.3%, respectively. The expressions of CD34, α-SMA and FAP-α in the stromal fibroblasts of normal, ASH and DCIS breast tissues did not show significant differences (χ(2) = 1.142, P = 0.896). The main immunophenotype of stromal fibroblasts in the tumor-host interface at the invasive front of ADH and DCIS lesions was CD34(+)α-SMA(+)FAP-α(+). There were statistically significant differences in the expression of CD34, α-SMA and FAP-α between IDC and ADH, DCIS and normal breast tissues (χ(2) = 8.351, P < 0.001). The immunophenotype of stromal fibroblasts in the IDC and DCIS-MI breast tissues was CD34(-) α-SMA(+) FAP-α(+).

CONCLUSIONSImmunophenotype conversion from CD34(+) α-SMA(-) FAP-α(-) to CD34(-) α-SMA(+)FAP-α(+) may be a sensitive indicator to judge whether DCIS has microinvasion. Detection of the immunophenotype conversion of stromal fibroblasts may be helpful to determine the presence of microinvasion, and to improve the diagnostic accuracy rate of DCIS.

Objective: To explore the prognostic value of the international prognostic index (IPI), the national comprehensive cancer network IPI(NCCN-IPI)and the age-adjusted IPI (aa-IPI) in diffuse large B cell lymphoma. Methods: A total of 311 patients with de novo diffuse large B-cell lymphoma (DLBCL) diagnosed from 2003 to 2012 in Nanfang hospital were included. All patients were divided into CHOP (cyclophosphamide, vincristine, doxorubicin, and prednisone) and R-CHOP (rituximab, CHOP) groups. Survival analysis was compared among IPI, NCCN-IPI and aa-IPI models. Discrimination of three different prognostic models was assessed using the Harrell’s C statistic. Results: A total of 311 patients were analyzed. Among them, 128 patients were treated with CHOP regimen and other 183 patients were treated with R-CHOP regimen. In CHOP groups, both NCCN-IPI (5-year OS: 59.7% vs 26.8%, P<0.001) and aa-IPI (5-year OS: 71.0% vs 25.0%, P<0.001) showed better risk stratification for low-intermediate and high-intermediate group than the IPI (5-year OS: 47.6% vs 36.6%, P=0.003). However, in the patients treated with R-CHOP, NCCN-IPI showed better risk stratification in low, low-intermediate, high-intermediate groups (5-year OS: 96.0% vs 83.0% vs 66.5%, P=0.009). According to the Harrell’s C statistic, C-index of IPI, NCCN-IPI and aa-IPI for overall survival (OS) were 0.546, 0.667, 0.698 in CHOP group and 0.611,0.654, 0.695 in R-CHOP group respectively. In patients younger than 60 years old, C-index of IPI, NCCN-IPI and aa-IPI for OS were 0.534, 0.675, 0.698 in CHOP group and 0.584, 0.648, 0.695 in R-CHOP respectively. Conclusion The NCCN-IPI is more powerful than IPI and aa-IPI in DLBCL patients receiving R-CHOP. aa-IPI is a preferable model in predicting prognosis than IPI and NCCN-IPI in anthracycline-based chemotherapy without rituximab.

Objective:The changes of serum inflammatory factors in patients with chronic obstructive pulmonary disease (COPD) with different traditional Chinese medicine (TCM) syndrome types were compared, and the characteristics and significance of inflammatory factors in COPD were discussed from the perspective of traditional Chinese and western medicine.Methods:A total of 100 patients with COPD who met the inclusion criteria and were admitted to Dongzhimen Hospital of Beijing University of Chinese Medicine from September 2021 to September 2022 were selected and divided into phlegm turbation obstructing lung group ( n=50) and lung and kidney qi deficiency group ( n=50) according to TCM syndrome types. Twenty healthy subjects in the same period were selected as control group. Serum levels of monocyte chemoattractant protein-1 (MCP-1), macrophage inflammatory protein-1α (MIP-1α), interleukin-6 (IL-6), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and other inflammatory factors were compared in each group. Results:The MCP-1, IL-6, ESR, CRP, white blood cell count (WBC) and procalcitonin (PCT) of COPD patients in phlegm turbation obstructing lung group were significantly higher than those in lung and kidney qi deficiency group (all P<0.05). The WBC, MCP-1, MIP-1α, IL-6, ESR and CRP of COPD patients in the lung and kidney qi deficiency group were significantly higher than those in the control group (all P<0.05). In the phlegm turbation obstructing lung group, the MIP-1α, MCP-1, IL-6, ESR, CRP, WBC, and PCT were significantly higher than those in the control group (all P<0.05). Conclusions:Patients with COPD have inflammatory reactions, and the inflammatory reactions of patients with phlegm turbation obstructing lung syndrome are more obvious than those with lung and kidney qi deficiency syndrome. The inflammatory factors MCP-1, MIP-1α, IL-6, ESR, CRP, WBC, PCT and other indicators could be used to judge the degree of COPD inflammation, which had certain clinical guiding significance for different syndrome types of COPD patients.

Objective:To analyze the prognosis of glucose metabolism and its impacting factors at 6-12 weeks postpartum in patients with abnormal blood glucose during pregnancy.Methods:In this cross-sectional study, a total of 192 patients with abnormal blood glucose during pregnancy enrolled and delivered in the maternity clinic of Daxing Teaching Hospital of Capital Medical University from December 1, 2019 to December 31, 2020 were collected. The 75 g oral glucose tolerance test (OGTT) was applied for diabetes screening at 6-12 weeks after delivery. According to the results of postpartum blood glucose, the patients were divided into two groups: postpartum normal blood glucose group (148 cases) and abnormal blood glucose group (44 cases). Hypothesis testing was used to compare the clinical data before, during and after the pregnancy between the two groups. Multi-factor logistic regression was performed to analyze the influencing factors of postpartum abnormal blood glucose in patients with abnormal blood glucose during pregnancy.Results:Among the 192 patients with abnormal blood glucose during pregnancy, the incidence of postpartum abnormal blood glucose was 22.92% (44/192), including 6 cases of diabetes mellitus (DM) (13.64%), 38 cases of impaired glucose tolerance (IGT) (86.36%). Neck circumference, waist circumference, multiparous women and insulin use during pregnancy in postpartum abnormal blood glucose group were all significantly higher than those in postpartum normal blood glucose group [34.25(33.00, 36.00) vs 33.55 (32.00, 35.00) cm, 87.00 (82.00, 93.00) vs 84.00 (78.00, 90.00) cm, 54.55% vs 37.16%, 18.18% vs 6.76%] (all P<0.05). Neck circumference ( OR=1.315, 95% CI: 1.026-1.685), multiparous women ( OR=2.261, 95% CI: 1.057-4.836), insulin use during pregnancy ( OR=3.767, 95% CI: 1.236-11.478) were positively correlated with the occurrence of postpartum abnormal blood glucose (all P<0.05). Conclusions:The incidence of postpartum abnormal blood glucose is high at 6-12 weeks postpartum in patients with abnormal blood glucose during pregnancy. Neck circumference, waist circumference, parity and insulin use during pregnancy are important impacting factors of postpartum abnormal blood glucose.

Objective:To investigate the behavior and emotion of trainees (residents) in the standardized residency training under the novel coronavirus pneumonia (NCP) epidemic, and adjust the training plan and mode of standardized residency training during the NCP epidemic according to the survey results.Methods:A real-name closed questionnaire survey was conducted among 40 residents (27 ultrasound majors and 13 other majors) in ultrasound department using the "Questionnaire Star" WeChat applet, including basic personal information, questions related to NCP, behavioral change survey, behavioral attitude survey and emotional status survey. All the collected data were further statistically analyzed by Chi-square test and rank sum test using SPSS 19.0Results:There were forty valid questionnaires and the participation rate was 100.0%. The accuracy of 24 NCP-related questions was not significantly different between residents majoring in ultrasound and other specialties [92.0%(596/648) vs. 93.6%(292/312), P>0.05]. All the residents had a good understanding of NCP. The main behaviors of going out were significantly reduced, while various behaviors of being at home were significantly increased. Their interest in learning declined. When the epidemic happened (or possibly) in the community or village they lived in, their negative emotions, such as nervousness, fear pessimism and depression, were obviously expressed. Network teaching and evaluation through WeChat public number were adopted and we guided residents to adjust their home behaviors and emotions according to the survey results. Conclusion:Under the NCP epidemic, the behaviors and emotions of residents had been extensively changed. The training center should adjust the teaching plan and mode of training in time, and provide more counselling service in psychology and learning for residents during the epidemic.

Objective:To evaluate the value of chemoradiotherapy and surgery in cervical esophageal cancer (CEC).Methods:Data of 459 patients with CEC from 2004 to 2017 were collected and retrospectively analyzed from the surveillance, epidemiology, and end results (SEER) database of National Cancer Institute (US). All patients were divided into the chemoradiotherapy group ( n=379) and surgery group ( n=80) according to the treatment methods. Survival analysis was performed by Kaplan-Meier method and survival curve was drawn. Multivariate survival analysis was conducted by Cox proportional hazards regression model. The death rate of different causes between two groups was calculated by cumulative incidence function (CIF). The differences of death rate between two groups were evaluated by Fine-Gray competing risk model. By analyzing the clinical characteristics and survival of CEC patients, the overall survival (OS) was compared between the surgery and chemoradiotherapy groups. Results:The 2- and 5-year survival rates in the chemoradiotherapy group were 43.1% and 22.4%, while those of the surgical group were 46.8% and 26.0%, respectively. No significant difference was observed in the OS between the chemoradiotherapy and surgery groups ( P=0.750). Cox multivariate analysis showed that treatment (surgery group vs. chemoradiotherapy group) was not an independent prognostic factor for OS. Based on the results of competing risk analysis, the risk of esophageal cancer-specific death in the chemoradiotherapy group was higher than that in the surgery group, and the difference was statistically significant between two groups ( P<0.001). The risk of other cause-specific death in the chemoradiotherapy group was lower than that in the surgery group ( P<0.001). The proportion of patients who died of oral, oropharyngeal, hypopharyngeal and laryngeal diseases in the surgery group was significantly higher than that in the chemoradiotherapy group(all P<0.001). Conclusions:No significant difference is observed in the OS of CEC patients treated with chemoradiotherapy or surgery. In the surgery group, the risk of esophageal cancer-specific death is lower, whereas the risk of other cause-specific death is higher compared with those in the chemoradiotherapy group.

Objective:To study the short-term clinical outcomes of different courses of antenatal corticosteroids (ACS) for preterm twins.Methods:From January 2017 to December 2021, preterm twins with gestational age (GA) 24-34 weeks admitted to the neonatal ward of our hospital and received ACS were retrospectively studied. The infants were assigned into single-course group, partial-course group and multiple-course group according to ACS courses. The short-term clinical outcomes were compared among the groups. SPSS software version 25.0 was used for statistical analysis.Results:A total of 286 infants were enrolled in this study, including 128 in single-course group, 89 in partial-course group and 69 in multiple-course group. Compared with single-course group, the risks of neonatal respiratory distress syndrome (RDS) in both partial-course group ( OR=2.332, 95% CI 1.028-5.293, P=0.043) and multiple-course group ( OR=3.872, 95% CI 1.104-13.584, P=0.034) were higher. The birth length in multiple-course group ( β=-0.016, 95% CI -0.029 - -0.002, P=0.024) was lower than single-course group. Conclusions:The risks of neonatal RDS in preterm twins are higher in partial-course and multiple-course of ACS. A full course of ACS should be used to prevent neonatal RDS until further evidence of effectiveness is available.
