Background/Aims: Exacerbating factors of ulcerative colitis (UC) are multiple and complex with individual influence. We aimed to evaluate the efficacy of disease control by searching and restricting inflammation trigger factors of UC relapse individually in daily clinical practice. Methods: Both patients with UC history or new diagnosis were asked to avoid dairy products at first doctor visit. Individual-reported potential trigger factors were restricted when UC flared up (Mayo endoscopy score ≥1) from remission status. The remission rate, duration to remission and medication were analyzed between the groups of factor restriction complete, incomplete and unknown. Results: The total remission rate was 91.7% of 108 patients with complete restriction of dairy product. The duration to remission of UC history group was significantly longer than that of new diagnosis group (88.5 days vs. 43.4 days, P=0.006) in patients with initial endoscopic score 2–3, but no difference in patients with score 1. After first remission, the inflammation trigger factors in 161 relapse episodes of 72 patients were multiple and personal. Milk/dairy products, herb medicine/Chinese tonic food and dietary supplement were the common factors, followed by psychological issues, non-dietary factors (smoking cessation, cosmetic products) and discontinuation of medication by patients themselves. Factor unknown accounted for 14.1% of patients. The benefits of factor complete restriction included shorter duration to remission (P<0.001), less steroid and biological agent use (P=0.022) when compared to incomplete restriction or factor unknown group. Conclusions Restriction of dairy diet first then searching and restricting trigger factors personally if UC relapse can improve the disease control and downgrade the medication usage of UC patients in daily clinical practice.

OBJECTIVE: To analyze the kinetic characteristics of lymphocyte subsets and myeloid-derived suppressor cell (MDSC) in patients who newly diagnosed intermediate- to high-risk aGVHD and treated with steroids-ruxolitinib as the first line therapy from a single-arm, open clinical trial (NCT04061876). METHODS: We prospectively observed the efficacy of 23 patients having intermediate- to high-risk aGVHD and treated with steroids-ruxolitinib as the first line therapy. The kinetic characteristics of lymphocyte subsets and MDSC were monitored, and then we compared them in steroids-ruxolitinib group (n=23), free-aGVHD group (n=20) and steroids group (n=23). RESULTS: Of the 23 patients, the CR rate was 78.26% (18/23) on day 28 after first-line treatment with steroids-ruxolitinib. On day 28 after treatment, patients had lower level of CD4⁺CD29⁺ T cells (P=0.08) than that of pre-treatment, whereas levels of other lymphocyte subsets in this study were higher than that of pre-treatment; CD4⁺CD29⁺ T cells in CR patients decreased, compared with refractory aGVHD patients. On day 28 of treatment, CD8⁺CD28^- T cells (P=0.03) significantly increased in patients with aGVHD than that in patients without aGVHD, so did CD8⁺CD28^- T / CD8⁺CD28⁺ T cell ratio (P=0.03). Compared with patients without aGVHD, patients with aGVHD had lower level of G-MDSC, especially on day 14 after allo-HSCT (P=0.04). Compared with pre-treatment, M-MDSC was higher in CR patients on day 3 and 7 post-treatment (P₃=0.01, P₇=0.03), e-MDSC was higher on day 28 post-treatment (P=0.01). Moreover, compared with CR patients, M-MDSC was lower in refractory aGVHD patients on day 3 post-treatment (P=0.01) and e-MDSC was lower on day 28 post-treatment (P=0.01). Compared with steroids group, MDSC in steroids-ruxolitinib group was higher, with the most significant difference in M-MDSC (P₃=0.0351; P₇=0.0142; P₁₄=0.0369). CONCLUSION We found that patients newly diagnosed intermediate- to high-risk aGVHD receiving first-line therapy with steroids-ruxolitinib achieved high response rate. Moreover, the novel first-line therapy has a small impact on the immune reconstitution of patients after allo-HSCT. Elevated MDSC might predict a better response in aGVHD patients receiving this novel first-line therapy. M-MDSC responded earlier to steroids-ruxolitinib than e-MDSC, G-MDSC.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.

Objective To explore and analyze the risk factors of severe falciparum malaria cases,and to provide evidence for early clinical prevention and intervention measures. Methods A total of 114 imported cases of falciparum malaria in Wuhan from March 2012 to November 2019 were selected,divided into mild group(n=87)and severe group(n=27),and logistic regression analysis was performed on the risk factors of severe disease. Results There were significant differences in length of stay, erythrocyte, hemoglobin, platelet, urea, creatinine, albumin, creatine kinase isoenzyme, lactate dehydrogenase, urine occulting blood and urine protein between mild group and severe group (P<0.05).Multivariate Logistic regression analysis showed that alanine aminotransferase (OR=0.167, 95%CI: 0.042-0.668), albumin (OR=24.843, 95% CI: 5.170-119.383), urea (OR=0.240,95%CI: 0.074-0.779) and occulted blood in urine (OR=0.204, 95%CI: 0.062-0.672) were independent influencing factors for the occurrence of severe falciparum malaria. Conclusion Patients with liver function damage and alanine aminotransferase increased by more than 2 times(≥80U/L),albumin decreased(<30g/L),renal function damage,increased urea nitrogen,hematuria and other abnormal results, the possibility of severe falsiparum malaria development should be highly suspected.

Objective: To explore the safety and effectiveness of stereotactic body radiation therapy (SBRT) for oligometastases from colorectal cancer (CRC). Methods: This is a prospective, single-arm phase Ⅱ trial. Patients who had histologically proven CRC, 1 to 5 detectable liver or lung metastatic lesions with maximum diameter of any metastases ≤5 cm were eligible. SBRT was delivered to all lesions. The primary endpoint was 3-year local control (LC). The secondary endpoints were treatment-related acute toxicities of grade 3 and above, 1-year and 3-year overall survival (OS) and progression free survival (PFS). Survival analysis was performed using the Kaplan-Meier method and Log rank test. Results: Petients from 2016 to 2019 who were treated in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. Forty-eight patients with 60 lesions were enrolled, including 37 liver lesions and 23 lung lesions. Forty-six patients had 1 or 2 lesions, with median diameter of 1.3 cm, the median biologically effective dose (BED(10)) was 100.0 Gy. The median follow-up was 19.5 months for all lesions. Twenty-five lesions developed local failure, the median local progression free survival was 15 months. The 1-year LC, OS and PFS was 70.2% (95% CI, 63.7%~76.7%), 89.0% (95% CI, 84.3%~93.7%) and 40.4% (95%CI, 33.0%~47.8%). The univariate analysis revealed that planning target volume (PTV) and total dose were independent prognostic factors of LC (P<0.05). For liver and lung lesions, the 1-year LC, OS and PFS was 58.7% and 89.4% (P=0.015), 89.3% and 86.5% (P=0.732), 30.5% and 65.6% (P=0.024), respectively. No patients developed acute toxicity of grade 3 and above. Conclusion: SBRT is safe and effective treatment method for oligometastases from CRC under precise respiratory motion management and robust quality assurance.

Objective:To analyze the functions and indications， formulation， dosage form and medication characteristics of Chinese patent medicines in the 2020 edition of Chinese Pharmacopoeia （part Ⅰ） for treating cough of children， and to provide ideas for the clinical rational application and provide reference for the research and development of new cough medicines for children. Method:The name， dosage form， formulation， functions and indications， usage and dosage， and other information of Chinese patent medicines for cough were collected from the 2020 edition of Chinese Pharmacopoeia （part Ⅰ）， then relevant information was input into Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine v2.0， and data analysis and mining were carried out through the analysis module of prescription medication rule， VOSviewer 1.6.14 was used to make drug clustering network view of Chinese patent medicines for the treatment of exogenous wind cold， exogenous wind heat and phlegm heat cough. Result:In the 2020 edition of Chinese Pharmacopoeia （part Ⅰ）， a total of 75 kinds of Chinese patent medicines for treating cough of children were collected， including 34 kinds of Chinese patent medicines for adults and children， 41 kinds of Chinese patent medicines for children only. There were 7 types of traditional Chinese medicine syndromes， such as wind-cold attacking the lung， wind-heat invading the lung and phlegm-heat obstructing the lung. There were 45 Chinese patent medicines for treating exogenous cough， accounting for 60%， among which 35 kinds were used for exogenous wind-heat cough and 10 kinds were used for wind-cold cough. There were 30 kinds of Chinese patent medicines for treating internal injury cough， including 19 kinds of medicines for phlegm heat obstructing the lung， 4 kinds of medicines for phlegm dampness containing the lung and phlegm food stagnation， 2 kinds of medicines for Yin-deficiency lung heat， 1 kind of medicine for the lung and spleen Qi-deficiency. The formulation analysis showed that Glycyrrhizae Radix et Rhizoma， Platycodonis Radix， Scutellariae Radix， Armeniacae Semen Amarum and Citri Reticulatae Pericarpium appeared frequently， which were mainly cold， bitter and sweet herbs， mainly belonged to the lung and stomach meridians. According to the analysis of administration and dosage forms， 71 kinds of Chinese patent medicines were administered through gastrointestinal tract， including 20 kinds of granules， 15 kinds of oral liquids， others included syrups， pills， capsules， tablets， powers， etc. Only 2 suppositories and 2 injections were administered by nongastrointestinal tract. The usage and dosage of most Chinese patent medicines were not clear. Conclusion:In the 2020 edition of Chinese Pharmacopoeia （part Ⅰ）， the main syndromes of Chinese patent medicines for cough of children are exogenous wind-heat and phlegm-heat obstruction in the lung. Most of the Chinese medicines are cold， bitter and sweet， and their meridians are mainly lung and stomach meridians. Scutellariae Radix， Lonicerae Japonicae Flos and Forsythiae Fructus are the most common medicines of exogenous wind heat syndrome. Perillae Folium， Citri Reticulatae Pericarpium and Ephedrae Herba are the most common medicines of exogenous wind cold syndrome. Meanwhile， Scutellariae Radix， Platycodonis Radix and Armeniacae Semen Amarum are the most common medicines of phlegm heat obstructing the lung syndrome. At present， the dosage forms of Chinese patent medicines used for treating cough of children are too few and the dosage labeling is not comprehensive， so it is necessary to further strengthen the research and development of new Chinese medicines suitable for characteristics of children.
