Objective:To investigate the clinical and pathological characteristics and prognosis of upper tract urothelial carcinoma (UTUC) with concurrent other histological variants.Methods:The clinical data of 566 UTUC patients admitted to Peking University People's Hospital from January 2007 to April 2021 were retrospectively analyzed. Among them, 289 were males and 277 were females, with an average age of (67.3±10.0)years old. Among the patients, 97 had a history of smoking, 29 had undergone kidney transplantation, 120 had diabetes, 76 had coronary heart disease, 146 had hyperlipidemia, 271 had hypertension, and 50 had a history of chronic kidney disease. Among the UTUC cases, 366 had concurrent hydronephrosis, 55 had concurrent bladder cancer, and 43 had a history of previous bladder cancer. The distribution included 210 cases of renal pelvis carcinoma, 5 cases of carcinoma at the renal pelvis-ureter junction, 226 cases of ureteral carcinoma, and 125 cases of multifocal tumors. Patients were classified into the pure UTUC group and the UTUC with concurrent other histological variants group based on postoperative pathology, and their clinical and pathological features were compared. Logistic regression analysis was used to explore risk factors for the occurrence of histological variations in UTUC. The log-rank test was employed to compare the overall survival (OS) and cancer-specific survival (CSS) between the two groups, while Cox regression analysis was performed to investigate prognostic factors.Results:Among the 566 cases, 511 were pure UTUC and 55 were UTUC with concurrent other histological variants. Among the latter, 30 cases had squamous differentiation, 6 had glandular differentiation, 5 had mucinous differentiation, 5 had sarcomatoid carcinoma, 2 had micropapillary carcinoma, 2 had neuroendocrine carcinoma, 1 had giant cell carcinoma, and 4 had other mixed histological variations. The proportion of patients with a history of kidney transplantation was higher in the UTUC with concurrent histological variants group than that in the pure UTUC group [14.5% (8/55) vs. 4.1% (21/511)], with statistically significant difference ( P=0.003). In the UTUC with concurrent histological variants group, the proportion of postoperative high-grade tumors [98.2% (54/55) vs. 80.2% (410/511)], muscle-invasive tumors [89.1% (49/55) vs. 68.1% (348/511)], lymph node metastasis tumors [10.9% (6/55) vs. 2.3% (12/511)], and maximum tumor diameter [(3.60±2.64) cm vs. (2.96±1.98) cm] were higher than those in the pure UTUC group ( P<0.05). Multivariate logistic regression analysis showed that a history of kidney transplantation ( OR=4.991, 95% CI 1.749-13.615, P=0.002) was an independent predictive factor for the occurrence of histological variants. Follow-up was conducted for 1 to 174 months, with a median follow-up time of 32.8 months. UTUC with concurrent histological variants was significantly associated with worse OS and CSS ( P<0.05). Multivariate Cox regression analysis indicated that histological variants were an independent risk factor for OS ( HR=1.860, 95% CI 1.228-2.816, P=0.003) and CSS ( HR=2.146, 95% CI 1.349-3.412, P=0.001). Conclusions:UTUC with concurrent other histological variants exhibited higher postoperative tumor grade and stage compared to pure UTUC, and UTUC with concurrent other histological variants was an independent risk factor for worse prognosis.

As a recognized rare and highly fatal disease, hereditary angioedema (HAE) is difficult to diagnose and characterized by recurrent edema involving the head, limbs, genitals and larynx, etc. Diagnosis of HAE is not difficult. However, low incidence and lack of clinical characteristics lead to difficulty of doctors on timely diagnosis and correct intervention for HAE patients. Therefore, it is crucial to improve the awareness of this disease and prevent its recurrence. for HAE patients. In view of absent cognition of doctors and the general public on HAE, patients often suffer from sudden death or become disabled due to laryngeal edema which cannot be treated in time. Thus, based on the Internet mobile terminal platform, the team set up an all-day rapid emergency response system which is provided for HAE patients by setting up "one-click help". The aim is to offer optimization on overall management of HAE and designed the intelligent follow-up management to provide timely assistance and specialized suggestion for patients with acute attacks.

Allergic diseases affect about 40% of the world's population. Environmental factors are important in the occurrence and development of allergic diseases. Dust mites are one of the most important allergens in the indoor environment. The World Health Organization proposes the "four-in-one, combination of prevention and treatment" treatment principle for allergic diseases, in which environmental control to avoid or reduce allergens is the first choice for treatment. Modern people spend much more time at home (including sleeping) than outdoors, and the control of the home environment is particularly critical. This practice introduces the hypoallergenic home visit program, which including home environment assessment, environmental and behavioral intervention guidance, and common household hypoallergenic supplies and service guidance for the patient's home environment. The real-time semi-quantitative testing of dust mite allergens, qualitative assessments of other indoor allergens, record of patients' household items and lifestyle, and precise, individualized patient prevention and control education will be conducted. The hypoallergenic home visit program improves the doctors' diagnosis and treatment data dimension, and becomes a patient management tool for doctors outside the hospital. It also helps patients continue to scientifically avoid allergens and irritants in the environment, effectively build a hypoallergenic home environment, reduce exposure to allergens in the home environment, and achieve the goal of combining the prevention and treatment of allergic diseases.

Objective: To investigate the clinical characteristics of hospitalized children infected with the Omicron variant in Kunming after the withdrawal of non-pharmaceutical interventions (NPI) and analyze the risk factors of severe cases. Methods: Clinical data was retrospectively collected from 1 145 children with SARS-CoV-2 Omicron infection who were hospitalized in six tertiary grade A hospitals in Kunming from December 10th, 2022 to January 9th, 2023. According to clinical severity, these patients were divided into the general and severe SARS-CoV-2 groups, and their clinical and laboratory data were compared. Between-group comparison was performed using t-test, chi-square test and Mann-Whitney U test. Spearman correlation test and multivariate Logistic regression analysis were used to determine the risk factors of severe illness. Results: A total of 1 145 hospitalized patients were included, of whom 677 were male and 468 female. The age of these patients at visit was 1.7 (0.5, 4.1) years. Specifically, there were 758 patients (66.2%) aged ≤3 years at visit and 387 patients (33.8%) aged >3 years. Of these children, 89 cases (7.8%) had underline diseases and the remaining 1 056 cases (92.2%) had no combined diseases. Additionally, of all the patients, 319 cases (27.9%) were vaccinated with one or two doses of SARS-CoV-2 vaccine, 748 cases (65.3%) had acute upper respiratory tract infection (AURTI), and six cases died (0.5%). A total of 1 051 cases (91.8%) were grouped into general SARS-CoV-2 group and 94 cases (8.2%) were grouped into severe SARS-CoV-2 group. Compared with the general cases, the severe cases showed a lower rate of SARS-CoV-2 vaccination and younger median age, lower lymphocyte count, as well as proportions of CD8+T lymphocyte (36 cases (38.3%) vs. 283 cases (26.9%), 0.5 (2.6, 8.0) vs. 1.6 (0.5, 3.9) years, 1.3 (1.0, 2.7) ×109 vs. 2.7 (1.3,4.4)×109/L, 0.17 (0.12, 0.24) vs. 0.21 (0.15, 0.16), respectively, χ2=4.88, Z=-2.21,-5.03,-2.53, all P<0.05). On the other hand, the length of hospital stay, proportion of underline diseases, ALT, AST, creatine kinase isoenzyme, and troponin T were higher in the severe group compared to those in the general group ((11.6±5.9) vs. (5.3±1.8) d, 41 cases (43.6%) vs. 48 cases (4.6%), 67 (26,120) vs. 20 (15, 32) U/L, 51 (33, 123) vs. 44 (34, 58) U/L、56.9 (23.0, 219.3) vs. 3.6 (1.9, 17.9) U/L, 12.0 (4.9, 56.5) vs. 3.0 (3.0, 7.0) ×10-3 pg/L,respectively, t=-20.43, χ2=183.52, Z=-9.14,-3.12,-6.38,-3.81, all P<0.05). Multivariate regression analysis indicated that increased leukocyte count (OR=1.88, 95%CI 1.18-2.97, P<0.01), CRP (OR=1.18, 95%CI 1.06-1.31, P<0.01), ferritin (OR=1.01, 95%CI 1.00-1.00, P<0.01), interleukin (IL)-6 (OR=1.05, 95%CI 1.01-1.08, P=0.012), D-dimer (OR=2.56, 95%CI 1.44-4.56, P<0.01) and decreased CD4+T lymphocyte (OR=0.84, 95%CI 0.73-0.98, P=0.030) were independently associated with the risk of severe SARS-CoV-2 in hospitalized children with Omicron infection. Conclusions: After the withdrawal of NPI, the pediatric inpatients with Omicron infection in Kunming were predominantly children younger than 3 years of age, and mainly manifested as AURTI with relatively low rate of severe SARS-CoV-2 infection and mortality. Elevated leukocyte counts, CRP, ferritin, IL-6, D-dimer, and decreased CD4+T lymphocytes are significant risk factors for developing severe SARS-CoV-2 infection.

Objective: To analyze the clinical characteristics of children with Burkitt lymphoma (BL) and to summarize the mid-term efficacy of China Net Childhood Lymphoma-mature B-cell lymphoma 2017 (CNCL-B-NHL-2017) regimen. Methods: Clinical features of 436 BL patients who were ≤18 years old and treated with the CNCL-B-NHL-2017 regimen from May 2017 to April 2021 were analyzed retrospectively. Clinical characteristics of patients at disease onset were analyzed and the therapeutic effects of patients with different clinical stages and risk groups were compared. Survival analysis was performed by Kaplan-Meier method, and Cox regression was used to identify the prognostic factors. Results: Among 436 patients, there were 368 (84.4%) males and 68 (15.6%) females, the age of disease onset was 6.0 (4.0, 9.0) years old. According to the St. Jude staging system, there were 4 patients (0.9%) with stage Ⅰ, 30 patients (6.9%) with stage Ⅱ, 217 patients (49.8%) with stage Ⅲ, and 185 patients (42.4%) with stage Ⅳ. All patients were stratified into following risk groups: group A (n=1, 0.2%), group B1 (n=46, 10.6%), group B2 (n=19, 4.4%), group C1 (n=285, 65.4%), group C2 (n=85, 19.5%). Sixty-three patients (14.4%) were treated with chemotherapy only and 373 patients (85.6%) were treated with chemotherapy combined with rituximab. Twenty-one patients (4.8%) suffered from progressive disease, 3 patients (0.7%) relapsed, and 13 patients (3.0%) died of treatment-related complications. The follow-up time of all patients was 24.0 (13.0, 35.0) months, the 2-year event free survival (EFS) rate of all patients was (90.9±1.4) %. The 2-year EFS rates of group A, B1, B2, C1 and C2 were 100.0%, 100.0%, (94.7±5.1) %, (90.7±1.7) % and (85.9±4.0) %, respectively. The 2-year EFS rates was higher in group A, B1, and B2 than those in group C1 (χ2=4.16, P=0.041) and group C2 (χ2=7.21, P=0.007). The 2-year EFS rates of the patients treated with chemotherapy alone and those treated with chemotherapy combined with rituximab were (79.3±5.1)% and (92.9±1.4)% (χ2=14.23, P<0.001) respectively. Multivariate analysis showed that stage Ⅳ (including leukemia stage), serum lactate dehydrogenase (LDH)>4-fold normal value, and with residual tumor in the mid-term evaluation were risk factors for poor prognosis (HR=1.38,1.23,8.52,95%CI 1.05-1.82,1.05-1.43,3.96-18.30). Conclusions: The CNCL-B-NHL-2017 regimen show significant effect in the treatment of pediatric BL. The combination of rituximab improve the efficacy further.

ObjectiveTo explore the guidance value of “treatment of disease in accordance with three conditions” theory in the prevention and treatment of corona virus disease 2019(COVID-19) based on the differences of syndromes and traditional Chinese medicine(TCM) treatments in COVID-19 patients from Xingtai Hospital of Chinese Medicine of Hebei province and Ruili Hospital of Chinese Medicine and Dai Medicine of Yunnan province and discuss its significance in the prevention and treatment of the unexpected acute infectious diseases. MethodDemographics data and clinical characteristics of COVID-19 patients from the two hospitals were collected retrospectively and analyzed by SPSS 18.0. The information on formulas was obtained from the hospital information system (HIS) of the two hospitals and analyzed by the big data intelligent processing and knowledge service system of Guangdong Hospital of Chinese Medicine for frequency statistics and association rules analysis. Heat map-hierarchical clustering analysis was used to explore the correlation between clinical characteristics and formulas. ResultA total of 175 patients with COVID-19 were included in this study. The 70 patients in Xingtai,dominated by young and middle-aged males,had clinical symptoms of fever, abnormal sweating,and fatigue. The main pathogenesis is stagnant cold-dampness in the exterior and impaired yin by depressed heat, with manifest cold, dampness, and deficiency syndromes. The therapeutic methods highlight relieving exterior syndrome and resolving dampness, accompanied by draining depressed heat. The core Chinese medicines used are Poria,Armeniacae Semen Amarum,Gypsum Fibrosum,Citri Reticulatae Pericarpium,and Pogostemonis Herba. By contrast,the 105 patients in Ruili, dominated by young females, had atypical clinical symptoms, and most of them were asymptomatic patients or mild cases. The main pathogenesis is dampness obstructing the lung and the stomach, with obvious dampness and heat syndromes. The therapeutic methods are mainly invigorating the spleen, resolving dampness, and dispersing Qi with light drugs. The core Chinese medicines used are Poria,Atractylodis Macrocephalae Rhizoma,Glycyrrhizae Radix et Rhizoma,Coicis Semen,Platycodonis Radix,Lonicerae Japonicae Flos, and Pogostemonis Herba. ConclusionThe differences in clinical characteristics, TCM syndromes, and medication of COVID-19 patients from the two places may result from different regions,population characteristics, and the time point of the COVID-19 outbreak. The “treatment of disease in accordance with three conditions” theory can help to understand the internal correlation and guide the treatments.

ObjectiveTo establish the determination for index components in benchmark samples of Erdongtang, and clarify the content and transfer rate rages of index components in 15 batches of benchmark samples, and to explore the quantity transfer of index components of decoction pieces to benchmark samples. MethodFifteen batches of benchmark samples were prepared, the contents of mangiferin, baicalin and glycyrrhizic acid were determined by high performance liquid chromatography (HPLC)-diode array detector (DAD), the mobile phase was acetonitrile (A)-0.1% formic acid aqueous solution (B) for gradient elution (0-10 min, 10%-17%A; 10-25 min, 17%-19%A; 25-28 min, 19%-25%A; 28-45 min, 25%-33%A; 45-46 min, 33%-45%A; 46-60 min, 45%-55%A), detection wavelength was set at 254 nm. Contents of timosaponin BⅡ and the sum of protoneodioscin and protodioscin were determined by HPLC-evaporative light scattering detector (ELSD), the mobile phase was acetonitrile (A)-water (B) for gradient elution (0-20 min, 24%A; 20-25 min, 24%-27%A; 25-33 min, 27%-28%A; 33-36 min, 28%-90%A; 36-41 min, 90%-24%A). ResultThe methodological verification of the established method was good, which could be used for determination of five index components in benchmark samples. The content ranges of mangiferin, baicalin, glycyrrhizic acid, timosaponin BⅡ, and the sum of protoneodioscin and protodioscin in 15 batches of benchmark samples of Erdongtang were 0.14%-0.23%, 2.40%-3.37%, 0.07%-0.44%, 0.43%-0.95%, and 0.15%-0.47%, the transfer rate ranges of them were 33.90%-52.15%, 84.46%-105.61%, 22.59%-93.86%, 38.07%-61.43%, and 53.28%-96.11%, respectively. ConclusionThe consistencies of transfer rate of mangiferin, baicalin, timosaponin BⅡ and the sum of protoneodioscin and protodioscin (except glycyrrhizic acid) between decoction pieces and benchmark samples of Erdongtang are good, indicates that the transfer rates of 4 index components are stable during the preparation process of benchmark samples, which can provide data support for research and development of the compound preparation of this formula.
