Objective: To investigate the correlation between tumor size, tumor location, and prognosis in patients with early-stage endometrial cancer (EC) receiving adjuvant radiotherapy. Methods: Data of patients who had been treated for stage I–II EC from March 1999 to September 2017 in 13 tertiary hospitals in China was screened. Cox regression analysis was performed to investigate associations between tumor size, tumor location, and other clinical or pathological factors with cancer-specific survival (CSS) and distant metastasis failurefree survival (DMFS). The relationship between tumor size as a continuous variable and prognosis was demonstrated by restricted cubic splines. Prognostic models were constructed as nomograms and evaluated by Harrell’s C-index, calibration curves and receiver operating characteristic (ROC) curves. Results: The study cohort comprised 805 patients with a median follow-up of 61 months and a median tumor size of 3.0 cm (range 0.2–15.0 cm). Lower uterine segment involvement (LUSI) was found in 243 patients (30.2%). Tumor size and LUSI were identified to be independent prognostic factors for CSS. Further, tumor size was an independent predictor of DMFS. A broadly positive relationship between poor survival and tumor size as a continuous variable was visualized in terms of hazard ratios. Nomograms constructed and evaluated for CSS and DMFS had satisfactory calibration curves and C-indexes of 0.847 and 0.716, respectively. The area under the ROC curves for 3- and 5-year ROC ranged from 0.718 to 0.890. Conclusion Tumor size and LUSI are independent prognostic factors in early-stage EC patients who have received radiotherapy. Integrating these variables into prognostic models would improve predictive ability.

Concurrent chemoradiotherapy (CCRT) refers to the simultaneous treatment of chemotherapy and radiotherapy, and the effect of radiotherapy is enhanced with low-dose chemotherapy, which can reduce tumor recurrence and metastasis and improve clinical prognosis of patients. At present, the main factors for the increase of radiosensitivity of concurrent chemotherapy is that concurrent chemotherapy prevents the repair of tumor cells, and chemotherapy and radiotherapy act on different cell cycles and have synergistic effects. However, even for patients with locally advanced cervical cancer (LACC) who have undergone CCRT, the 5-year survival rate is only 60%, which is still not ideal. In order to improve the efficacy, researchers have conducted a series of exploratory studies, which consist of the combination of targeted drugs and immunodrugs, and neoadjuvant regimens before CCRT, etc. Although targeted or immunologic drugs are effective treatment of LACC, in view of the lack of large-scale evidence-based medical evidence, multi-center prospective and randomized phase III clinical trials and high-level articles are needed to improve the level of evidence-based medicine. This consensus summarizes several key evidence-based medical studies published recently, especially the clinical research progress in targeted and immunological therapies, providing reference for domestic peers.

Objective:To assess the reliability,and validity of the Chinese version of a short-form of Health Literacy Dental scale(HeLD-14)in 3-6 years old preschool children's parents.Methods:The study population consisted of those eligible 3-6 years old preschool children's parents in Yanqing Dis-trict,Beijing,China in 2021.A total of 1 479 preschool children's parents were surveyed by question-naire to understand the general situation of parents and oral health literacy related content.SPSS 21.0 and Mplus 7.4 were used for statistical analysis.Through Cronbach's α coefficient,confirmatory factor a-nalysis,Pearson correlation calculation,Student's t test and other methods,the internal consistency reli-ability,structure validity,calibration validity and discrimination validity of the scale were evaluated.Re-sults:The Cronbach's α coefficient of Chinese version HeLD-14 scale was 0.958,and Cronbach's α co-efficient of different constructs ranged from 0.778 to 0.963.The confirmatory factor analysis showed that the factor loadings of each item of the Chinese version HeLD-14 scale were between 0.719 and 0.977(P＜0.001),root-mean-square error of approximation(RMSEA)=0.04,comparative fix index(CFI)=0.992,Tucker-Lewis index(TLI)=0.988,and the model had good goodness of fit.The total score of the Chinese version HeLD-14 scale and the scores of the dimension of concerning,understanding,sup-porting,financial burden,medical treatment,communication,and application were all positively correla-ted with general self-efficacy,and the correlation coefficients were 0.439,0.406,0.370,0.344,0.346,0.367,0.373,0.390,respectively(P all＜0.05).For parents in the high group with the top 27％HeLD-14 score,the average HeLD-14 score was 69.27±1.06,which was higher than the low group with the bottom 27％HeLD-14 score,41.29±11.09(t=48.13,P＜0.01).Conclusion:The Chinese version HeLD-14 scale has good reliability and validity in the 3-6 years old preschool children's parents,and can be used as a tool to assess the oral health literacy of parents of preschool children.

Liver transplantation(LT)is the only effective treatment for hepatopulmonary syndrome(HPS).Moreover,perioperative refractory hypoxemia(pRH)is a prevalent life-threatening condition and has extremely limited treatment options.Here,we report three patients with HPS who experienced pRH after LT and were consecutively treated with different salvage therapies,ephedrine inhalation,intravenous use of methylene blue with nitric oxide(NO)inhalation,and NO inhalation alone.The results showed that unresolved severe hypoxia may induce fatal morbidity such as early biliary leakage and acute kidney injury.Early initiation of NO inhalation,rather than ephedrine,can significantly improve oxygenation in patients with pRH and may help prevent hypoxia-related complications.Therefore,based on the response to these exploratory salvage treatments,we further demonstrate the unique ventilation-perfusion mismatch pathophysiology in specific lung regions during pRH in HPS.We propose that early inhalation of NO is an important treatment option to rescue severe hypoxia in patients with HPS during the perioperative period of LT.

Actinomycosis is a rare chronic granulomatous disease characterized by granuloma formation and tissue fibrosis with sinus tracts,often misdiagnosed due to its similarity to many infectious and non-infectious diseases.This report presents a case of a 60-year-old female with more than 10 years history of rheumatoid arthritis who developed actinomycosis infection after long-term treatment with immunosuppressants and biologics,including methotrexate,leflunomide,and infliximab,leading to recurrent joint pain,poorly controlled rheumatoid arthritis activity,and persistent elevation of white blood cell counts.Abdominal CT revealed a pelvic mass and right ureteral dilation.Pathological examination of cervical tissue showed significant neutrophil infiltration and sulfur granules,indicating actinomycosis.The patient received 18 months of doxycycline treatment for the infection and continued rheumatoid arthritis therapy with leflunomide,hydroxychloroquine sulfate,and tofacitinib,resulting in improved joint symptoms and normalized white blood cell counts.After 2 years of follow-up,the patient remained stable with no recurrence.This case highlights the importance of clinicians being vigilant for infections,particularly chronic,occult infections from rare pathogens,in rheumatoid arthritis patients on potent immunosuppressants and biologics,advocating for early screening and diagnosis.

Objective:To explore the clinical short-term efficacy of venetoclax (Ven) combined with azacitidine (AZA) in treatment of newly treated and relapsed/refractory patients with acute myeloid leukemia (AML).Methods:The data of 18 newly treated and relapsed/refractory patients with AML who received Ven+AZA treatment in Suzhou Traditional Chinese Medicine Hospital Affiliated to Nanjing University of Chinese Medicine from April 2020 to June 2022 were retrospectively analyzed. The complete remission or complete remission with incomplete recovery of blood cell count (CR/CRi) and objective remission rate (ORR) [calculated as CR/CRi+partial remission (PR)] were analyzed in newly treated and relapsed/refractory patients or patients with different gene mutations. The patients were followed up until June 30, 2022, and the overall survival (OS) of relapsed/refractory patients was analyzed. The occurrence of adverse reactions was summarized.Results:The median age of the 18 patients was 58 years old (23-81 years old), 8 were males and 10 were females; 6 were newly treated and 12 were relapsed/refractory; the median follow-up time was 3 months (1-15 months). In 6 newly treated patients, after the first cycle of Ven+AZA, 5 cases achieved CR/CRi, and the ORR was 83.3% (5/6). In 12 relapsed/refractory patients, after the first cycle of Ven+AZA, 5 cases achieved CR/CRi, 3 achieved PR, and the ORR was 66.7% (8/12). Among the 18 patients, 7 cases had FLT3-ITD/TKD mutation, after the first cycle of Ven+AZA, 1 case achieved CR/CRi, 1 case achieved PR, and the ORR was 28.6% (2/7); 3 cases had NPM1 mutation combined with FLT3-ITD/TKD mutation, 1 case achieved CR/CRi, and the ORR was 33.3% (1/3); 4 cases had IDH1/2 mutation, and 3 cases of them combined with FLT3-ITD/TKD mutation, all of which were non-remission, and the other 1 relapsed/refractory patient combined with K/NRAS mutation achieved CR/CRi; among the 4 cases with K/NRAS mutation, 2 cases combined with FLT3-ITD/TKD mutation, including 1 case of NR and 1 case of PR, and the other 2 cases achieved CR/CRi, the ORR was 75.0% (3/4). Of the 12 relapsed/refractory patients, 6 died by the end of follow-up, with a median OS time of 2.6 months (1- 8 months), including 4 cases of disease progression and 2 cases of disease relapse; the 6 surviving patients had stable disease. All the 18 patients had ≥grade 3 hematologic adverse reactions, and non-hematologic adverse reactions included lung infection, nausea, vomiting and diarrhea.Conclusions:Ven+AZA treatment for newly treated and relapsed/refractory AML patients results in a high response rate with tolerable adverse reactions, but it is not effective in AML patients with FLT3-ITD/TKD mutation.

Objective:To investigate the efficacy and adverse reactions of moderately hypofractionated intensity modulated radiation therapy (IMRT) combined with androgen deprivation therapy (ADT) for locally advanced prostate cancer (LAPC).Methods:This study retrospectively analyzed the medical records of 40 LAPC patients who were admitted in The Second Hospital of Dalian Medical University during 2014-2020. The planning gross target volume (PGTV) dose for prostate gland and seminal vesicle gland was 64.8-70.0 Gy/25-28 f, 2.4-2.8 Gy/f and the dose of PGTVnd in 20 cases with positive pelvic lymph nodes was 60.0-64.4 Gy/25-28 f, 2.3-2.4 Gy/f. The dose of planning target volume (PTV) for the drainage area of pelvic lymph nodes was 45.0-50.4 Gy/25-28 f. The enrolled patients were treated with long-term ADT, including neoadjuvant, simultaneous, and adjuvant therapies. The efficacy and adverse reactions were evaluated. The prognostic factors affecting the biochemical failure-free survival (BFFS) were analyzed.Results:The median follow-up time was 31 months. The 2- and 3-year overall survival (OS) rates were 100% and 96.9%, respectively. The 1-, 2-, and 3-year BFFS rates were 90%, 76.8% and 72%, respectively. The 1-, 2-, and 3-year distant metastasis-free survival (DMFS) rates were 92.2%, 82.8% and 75.1%, respectively. Gleason (GS) score ( χ2=10.00, P < 0.05) and adjacent tissue invasion ( χ2=8.85, P<0.05) were prognostic factors related to BFFS for LAPC. Adjacent tissue invasion and GS 9-10 were independent poor prognostic factors. The incidence of acute urinary adverse reaction and rectal injury (grade≥2) was 7.5% and 20%, respectively. The incidence of late urinary adverse reaction and rectal injury (grade≥2) was 12.5% and 17.5%, respectively. Adverse reactions at grade 3-4 did not occur. Conclusions:The moderately hypofractionated IMRT combined with ADT is feasible for LAPC treatment, achieving satisfactory survival effects. 70 Gy/25-28 f, 2.5-2.8 Gy/f is a safe and effective moderate hypofraction scheme. Adjacent tissue invasion and GS score are prognostic factors related to BFFS for LAPC.

Objective:To investigate the etiology, clinical manifestations, clinicopathological features of cystic neutrophil granulomatous mastitis (CNGM).Methods:From Jan 2019 to Dec 2020, 95 CNGM cases diagnosed by biopsy pathology at Chongqing Hospital of Traditional Chinese Medicine and Chongqing Liangping District Hospitol of Traditional Chinese Medicine were reviewed.Results:There were 95 female patients, aged 21 to 50 years, with a median age of 32 years. Laboratory examination showed that 56% (53/95) cases had elevated rheumatoid antibody level, 27 % (26/95) had increased level of serum thyroid antibody, 15% (14/95) had elevated antineutrophil antibody, 35% (33/95) had increased ESR, 38% (36/95) had increased C-reactive protein. The positive rate of Gram-stained bacilli was 82% (78/95). Histology: pyogenic granuloma with lobule of breast as the center, the center of granuloma was cystic vacuole.Immunohistochemistry showed that the inflammatory cells in and around granuloma were mainly CD3 + cells, and CD4 + cells were more than CD8 + cells. Conclusions:The cystic neutrophilie granulo matous mastitis is a rare type of idiopathic granulomatous mastitis. The diagnosis of CNGM is dependent on its specific pathological features.
