OBJECTIVE: To investigate the therapeutic efficacy of using decitabine as maintenance therapy for patients with relapsed MDS/AML and as prophylactic therapy for patients with high-risk AML after allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: Clinical data of 10 patients with MDS/AML from November 2016 to May 2018 were analyzed retrospectively. Among 10 patients there were 4 cases of AML, 2 cases of MDS, and 4 cases of AML transformed from MDS (t-AML). The 10 patients were devided into 2 groups: the relapsed group (n=8) and the prophylactic group (n=2). In relapsed group the decitabine was used as maintenance therapy after achieved complete remission (CR) with decitabine chemotherapy. In prophylactic group the decitabine was used as prophylactic therapy if the patients didn't appear the symptom of graft-versus- host-disease (GVHD) during 30 to 45 d after allo-HSCT. Eight patients received G-CSF-mobilized donor lymphocyte infusion (DLI). The dosage of decitabine for maintenance therapy and prophylactic therapy was 5 mg/m for 7 to 10 days every 4 to 6 weeks, as 1 cycle, amount to 3 to 7 cycles. The dosage was adjusted by the endurance of patients. RESULTS: Until Nov 30, 2018, 7 out of 10 patients survived. The average survival time was 15.5±1.9 months. 1-year OS rate was 64.0%. Six patients appeared aGVHD, and four patients appeared cGVHD. CONCLUSION The usage of decitabine combined with DLI in patients with relapsed MDS/AML and high-risk AML after allo-HSCT can prolong lives of patients, reduce relapsed rate, and provide the probability for long time survival.

OBJECTIVE: To investigate the clinical efficacy, related side-effectt and long-term survival condition of Philadelphia chromosome positive acute lymphoblastic leukemia (Ph ALL) patients treated with second generation TKI dasatinib and chemotherapy followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: Clinical data of 19 newly diagnosed as Ph ALL patients treated by dasatinib, chemotherapy and allo-HSCT from January 2012 to September 2018 were collectd and analyzed. RESULTS: There were 10 males and 9 females with median age of 29 years old. 14 patients were BCR/ABL P190 positive while 5 with BCR/ABL P210 positive. Three patients had complex karyotype, and 3 cases were confirmed to have central nervous system leukemia. All the patients received treatment with the induction chemotherapy regimen of VDCLP and consolidation regimens such as HD-MTX and MAE. 11 patients (57.9%) received dasatinib during induction chemotherapy, 3 patients (15.8%) received dasatinib after remission and 5 patients (26.3%) received dasatinib to replace imatinib. Side-effect appeared in 3 patients including rash, edema and nausea. All the patients got morphological remission and 7 patients(63.6%) got MMR after 4 weeks of induction chemotheraphy. 17 patients (89.5%) got MMR and 15 patients(78.9%) got CMR before allo-HSCT. All the patients received related bone marrow and peripheral hematopoietic stem cell transplantation from related donors, the median time of WBC and platelet engraftment were 12 d and 14 d after transplantation, respectively. The incidence rate of aGVHD and cGVHD were 42.1% and 57.9% respectivety. 13 patients received therapy of dasatinib after HSCT but 7 patients discontinued because of severe headache, vomiting and serious effusions. All the patients were followed-up for the median time of 42 months, the 3-year and 5-year OS both were 94.4%, and 3-year and 5-year RFS of 81.9% and 71.6%, respectively. CONCLUSION First-line administration of dasatinib and chemotherapy followed by allo-HSCT for treatment of PhALL is effective and patients can well-tolerate, the patients long-tern survival maybe superior to that of the patients treated with first generation TKI.

OBJECTIVE: To investigate the efficacy and safety of arsenic trioxide combined with ATRA and chemo- therapy for treatment of relapsed acute promyelocytic leukemia (APL) patients. METHODS: The clinic data of 25 patients with relapse APL treated in our hospital from 1996 to 2013 were collected and analyzed. Among the 25 patients, 15 patients suffered first-time hematological relapse (HR), and the other 10 patients showed first-time molecular relapse (MR). The patients with first-time replase were treated with ATO+ATRA+Anthracycline re-induction chemotherapy. The clinical features, complete remission (CR) rate, overall survival (OS), disease-free survival (DFS) and adverse events after re-induction therapy were analyzed. RESULTS: Fourteen of 15 hematological relapsed patients achieved the second-time hematological complete remission (CR2) after re-induction therapy except one patient died of bleeding complication during the re-induction. 8 of 14 patient showed molecular complete remission (CRm) after two cycles of therapy with this regimen. Totally, eleven out of the 14 HR patients were alive without disease till the last follow-up, and 3 of the 14 HR patients died because of bleeding complications. All of the 10 molecular relapsed patients received the second CRm after treated by the regimen. Among these 10 patients, 6 patients suffered only once relapse and continued with the molecular CR2 status, and for the other 4 patients with more than two-relapses, only 1 survived untill 89.3 months after achieved second-time CRm, and other 3 patients died because of bleeding complications. CONCLUSION For relapsed APL patients, the treatment with ATO+ATRA+chemotherapy regimen after relapse still shows encouraging efficacy, no matter whether or not the application of ATO in the previous regimens. In addition, patients with more than two molecular relapses show a poor prognosis.

The current document is based on a consensus reached by a panel of experts from the Chinese Society of Allergy and the Chinese Society of Otorhinolaryngology-Head and Neck Surgery, Rhinology Group. Chronic rhinosinusitis (CRS) affects approximately 8% of Chinese adults. The inflammatory and remodeling mechanisms of CRS in the Chinese population differ from those observed in the populations of European descent. Recently, precision medicine has been used to treat inflammation by targeting key biomarkers that are involved in the process. However, there are no CRS guidelines or a consensus available from China that can be shared with the international academia. The guidelines presented in this paper cover the epidemiology, economic burden, genetics and epigenetics, mechanisms, phenotypes and endotypes, diagnosis and differential diagnosis, management, and the current status of CRS in China. These guidelines—with a focus on China—will improve the abilities of clinical and medical staff during the treatment of CRS. Additionally, they will help international agencies in improving the verification of CRS endotypes, mapping of eosinophilic shifts, the identification of suitable biomarkers for endotyping, and predicting responses to therapies. In conclusion, these guidelines will help select therapies, such as pharmacotherapy, surgical approaches and innovative biotherapeutics, which are tailored to each of the individual CRS endotypes.

The aim of this study is to o explore the diagnosis, treatment and prognosis of idiopathic subglottic stenosis （ISS） The clinical data of 15 patients with idiopathic subglottic stenosis treated in our department were analyzed retrospectively. The degree of stenosis was classified by the Cotton Airway grading system of Myer, with 8 cases of gradeⅡ, 4 cases of grade Ⅲ and 3 cases of grade Ⅳ. The time of follow-up of HTSS was 0.5-10 years. All 15 patients were successfully extubated without asphyxia, decannulation and wound nonunion. For patients with idiopathic subglottic stenosis in the non-progressive stage, active surgical treatment strategy should be adopted and treated individually. The prognosis is satisfactory.

Objective: To investigate the long-term effects of GnRHa treatment on final height gain, gonadal function, and body mass index(BMI) in children with central precocious puberty(CPP) or early and fast puberty(EFP), and to explore the influencing factors of height gain and early predictors. Methods: Fifty patients with CPP and 44 patients with EFP who were treated with GnRHa for more than 2 years were enrolled(80 females and 14 males). Body height, bone age, BMI, gonads hormone, uterus and ovarian volumes(female), testicular volume(male), and other parameters before and after treatment were measured. Results: (1)For girls: GnRHa plus GH treatment gained more final height compared with GnRHa treatment [(10.69±5.73) cm vs (7.42±5.76) cm, P<0.05]. Height lost >5cm at the initial treatment benefited much more for the final height compared with height lost<5cm [(10.65±3.32) cm vs (6.51±3.40) cm, P<0.01]. The proportion of overweight/obesity decreased when reaching the final height compared with the initial treatment and stopping the treatment. Serum LH level, uterine and ovarian volume were significantly decreased after stopping treatment compared with before treatment, and increased half a year to 1 year after stopping treatment.100% of girls had menarche and 95% reached the regular cycle 3 years after stopping treatment.(2)For boys: GnRHa plus GH treatment and GnRHa treatment gained height by(8.78±5.2) and(7.99±4.82) cm, respectively. Serum LH level and testicular volume were significantly decreased after stopping treatment as compared with those before treatment, and increased for half a year to 1 year after stopping treatment. Conclusion GnRHa treatment can significantly improve the final height for girls with CPP and EFP. The patients with more height lost could gain more height, which can be used as a predictor of height gain.

Objective: To analyze influencing factors for depressive symptoms in the elderly aged 65 years and older in 8 longevity areas in China. Methods: We recruited 2 180 participants aged 65 years and older in 8 longevity areas from Healthy Aging and Biomarkers Cohort Study, a sub-cohort of the Chinese Longitudinal Healthy Longevity Survey in 2017. Multivariate logistic regression analysis was performed to evaluate the relationships of socio-demographic characteristics, behavioral lifestyle, chronic disease prevalence, functional status, family and social support with depressive symptoms in the elderly. Results: The detection rate of depression symptoms was 15.0% in the elderly aged 65 years and older in 8 longevity areas of China, and the detection rate of depression symptoms was 11.5% in men and 18.5% in women. Multivariate logistic regression analysis results showed that the detection rate of depressive symptoms was lower in the elderly who had regular physical exercises (OR=0.44, 95%CI: 0.26-0.74), frequent fish intakes (OR=0.57, 95%CI: 0.39-0.83), recreational activities (OR=0.65, 95%CI: 0.44-0.96), social activities (OR=0.28, 95%CI: 0.11-0.73) and community services (OR=0.68, 95%CI: 0.50-0.93). The elderly who were lack of sleep (OR=2.04, 95%CI: 1.49-2.80), had visual impairment (OR=1.54, 95%CI: 1.08-2.18), had gastrointestinal ulcer (OR=2.97, 95%CI: 1.53-5.77), had arthritis (OR=2.63, 95%CI: 1.61-4.32), had higher family expenditure than income (OR=1.80, 95%CI: 1.17-2.78) and were in poor economic condition (OR=4.58, 95%CI: 2.48-8.47) had higher detection rate of depressive symptoms. Conclusion The status of doing physical exercise, fish intake in diet, social activity participation, sleep quality or vision, and the prevalence of gastrointestinal ulcers and arthritis were associated with the detection rate of depressive symptoms in the elderly.

Objective: To establish a prediction model for 6-year incidence risk of chronic kidney disease (CKD) in the elderly aged 65 years and older in China. Methods: In this prospective cohort study, we used the data of 3 742 participants collected during 2008/2009-2014 and during 2012-2017/2018 from Healthy Aging and Biomarkers Cohort Study, a sub-cohort of the Chinese Longitudinal Healthy Longevity Survey. Two follow up surveys for renal function were successfully conducted for 1 055 participants without CKD in baseline survey. Lasso method was used for the selection of risk factors. The risk prediction model of CKD was established by using Cox proportional hazards regression models and visualized through nomogram tool. Bootstrap method (1 000 resample) was used for internal validation, and the performance of the model was assessed by C-index and calibration curve. Results: The mean age of participants was (80.8±11.4) years. In 4 797 person years of follow up, CKD was found in 262 participants (24.8%). Age, BMI, sex, education level, marital status, having retirement pension or insurance, hypertension prevalence, blood uric acid, blood urea nitrogen and total cholesterol levels and estimated glomerular filtration rate in baseline survey were used in the model to predict the 6-year incidence risk of CKD in the elderly. The corrected C-index was 0.766, the calibration curve showed good consistence between predicted probability and observed probability in high risk group, but relatively poor consistence in low risk group. Conclusion The incidence risk prediction model of CKD established in this study has a good performance, and the nomogram can be used as visualization tool to predict the 6-year risk of CKD in the elderly aged 65 years and older in China.

Objective: To understand the consciousness of the cancer early treatment and its demographic and socioeconomic factors. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China (CanSPUC) from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The questionnaire collected personal information, the consciousness of the cancer early treatment and relevant factors. The Chi square test was used to compare the difference between the consciousness of the cancer early treatment and relevant factors among the four groups. The logistic regression model was used to analyze the influencing factors related to the consciousness of the cancer early treatment. Results: With the assumption of being diagnosed as precancer or cancer, 89.97% of community residents, 91.84% of cancer risk assessment/screening population, 93.00% of cancer patients and 91.52% of occupational population would accept active treatments (P<0.001). If the immediate family members were diagnosed as precancer or cancer, people who would encourage their family members to receive early treatment in the four groups accounted for 91.96%, 91.94%, 92.44% and 91.55%, respectively (P<0.001). The company employees, annual household income with 40 000 yuan and more and other three groups had a relatively better consciousness of the cancer early treatment (P<0.05). Male, widowed, unemployed and from the central and western regions had a relatively worse consciousness of the cancer early treatment (P<0.05). Conclusion Residents in urban China participants had a good consciousness of the cancer early treatment. The marital status, occupation, annual household income and residential regions were major factors related to the consciousness of the cancer early treatment.

PURPOSE: Extranodal natural killer/T-cell lymphoma, nasal type (ENKTL) is a rare subtype of non-Hodgkin lymphoma, and asparaginase-based regimens are the best first-line treatments. Data on the role of specific circulating lymphocyte subsets in the progression of ENKTL are limited. The aim of this study was to investigate the clinical correlation and distribution of circulating absolute CD4+ T-cell counts (ACD4Cs) in ENKTL. MATERIALS AND METHODS: We retrospectively searched medical records for 70 newly diagnosed ENKTL patients treated with pegaspargase-based regimens. Comparison of ACD4Cs as a continuous parameter in different groups was calculated. Univariate and multivariate analyses were used to assess prognostic factors for overall survival (OS) and progression-free survival (PFS). RESULTS: Stage III/IV, B symptoms, elevated lactate dehydrogenase, monocytopenia, high-intermediate and high risk International Prognostic Index (IPI) and Korean Prognostic Index (KPI), high risk Prognostic Index of Natural Killer Lymphoma (PINK), and lower lymphocytes were significantly associated with low ACD4C at diagnosis. With a median follow-up time of 32 months, patients who had an ACD4C < 0.30×109/L had a worse OS. Median OS was 11 months and median PFS was 5 months in the low ACD4C cohort. There were significant differences in both OS and PFS between the two cohorts. Moreover, multivariate Cox analysis identified ACD4Cs as an independent predictor for OS and PFS. CONCLUSION: Low ACD4Cs were associated with poorer survival and could act as a negative predictor for ENKTL patients treated with asparaginase-based regimens.
