Objective To evaluate the efficacy and safety of micafungin in the treatment of invasive fungal infections (IFI) in patients with acute leukemia.Methods A total of 133 IFI patients with acute leukemia received micafungin 150 mg once daily for 14 days.The clinical and mycological efficacies were evaluated on (7±2) days and(14±2) days of treatment.Meanwhile,the adverse events were recorded.The normally distributed data was compared using analysis of variance and nonnormal distributed data was analyzed using Wilcoxon rank-sum test.Results Among 133 IFI patients with acute leukemia,116 finished the 14-day micafungin treatment.The total clinical efficacy was 94.8% and the total mycological efficacy was 75.0% at (14±2) days of treatment.The fungus eliminate rates were 82.9%,66.7% and 55.6% against Monilia,Aspergillus and others,respectively.The clinical and mycological efficacies of (14±2)-day treatment were both higher than those of (7±2)-day treatment(X2=6.060,34.416.both P<0.05).The clinical efficacy was not related with age,sex,IFI diagnose,types of leukemia and combinative drugs (X2=26.541,P<0.05).The incidence of drug-related adverse events of micafungin was 3%among 133 patients,which included skin rash in 3 eases, diarrhea in 1 case. Only one case was discontinued because of severe skin rash and micafungin was well tolerant in other patients. Conclusion Treatment of micafungin 150 mg daily for 14 days is effective and safe in IFI patients with acute leukemia.

Objective To analyze the current status and influencing factors of occupational stress among firefighters in Shenzhen City. Methods A total of 5 434 first-line firefighters in Shenzhen City was selected as the study subjects using the judgment sampling method. The Job Content Questionnaire was used evaluate the occupational stress level. Results The detection rate of occupational stress in the study subjects was 52.5% (2 854/ 5 434). The result of dichotomous logistic regression analysis results showed that the risk of occupational stress was higher in firefighters who had a bachelor's degree or above than in those who had junior high school or below (P<0.01), the risk of occupational stress in those with irregular meals was higher than those with regular meals (P<0.01), and the risk of occupational stress was lower in those who exercised 1-3 times a month or ≥3 times a week than in those who did no daily exercise (all P<0.05). The risk of occupational stress was higher with older the weekly working hours, the more frequent the injury and the more firefighting workload (all P<0.01). The risk of occupational stress in firefighters who stand for a long time was higher than that in workers who not-stand for a long time (P<0.05). Conclusion The detection rate of occupational stress among the firefighters in Shenzhen City is relatively high. Educational level, dietary habits, daily exercise, weekly working hours, injury frequency, long-standing work and firefighting workload are all influencing factors for occupational stress in firefighters.

Objective:To retrospectively analyze clinical efficacy and safety of omalizumab in the treatment of chronic urticaria (CU) in southern Zhejiang, China.Methods:A retrospective observational study was conducted on CU patients who received omalizumab treatment at the First Affiliated Hospital of Wenzhou Medical University from January 1st, 2018 to August 1st, 2021. Through the outpatient follow-up visits, the disease activity, condition control, and quality of life were evaluated using the 7-day urticaria activity score (UAS7) , urticaria control test (UCT) , and dermatology life quality index (DLQI) . In addition, changes in disease condition, recurrence after withdrawal, and adverse events were assessed. Independent-sample t test was used for intergroup comparisons of normally distributed measurement data, Wilcoxon signed-rank sum test or Kruskal-Wallis H test was used for comparisons of non-normally distributed measurement data, and chi-square test or Fisher′s exact test was used for comparisons of enumeration data. Results:A total of 252 CU patients with poor response to antihistamines were included, with a baseline UCT score of 5.0 ± 2.4 points, a UAS7 score of 25.6 ± 6.2 points, and a DLQI score of 17.5 ± 4.7 points; among them, 204 (81.0%) were treated with omalizumab at an initial dose of 300 mg, and 48 (19.0%) with omalizumab at an initial dose of 150 mg. At the end points (12.0 ± 1.4 months after the start of treatment) , an overall control rate of 90.3% (224/248) was achieved after the omalizumab treatment; concretely, 137 (55.2%) patients achieved complete control (UCT = 16 points) , 87 (35.1%) achieved partial control (12 points ≤ UCT < 16 points) , and 24 (9.7%) showed no response (UCT < 12 points) , while 10 with partial response shifted to complete control after dose increase. During the treatment period, recurrence occurred in 50 patients (36.5%) , of whom 32 patients opted for retreatment with omalizumab, and then 30 (93.8%) achieved partial or complete control. Adverse events were reported in 8 patients (3.2%) , and all were mild or moderate.Conclusion:Omalizumab was effective in the real-world treatment of CU, and could improve patients′ quality of life, with a favorable safety profile.

Objective:To investigate the effect of posture training on head posture in myogenic temporomandibular disor-ders(TMD)patients with forward head posture. Method:Forty-five myogenic TMD patients(6 male,39 female;age 29.24±6.13y)were recruited from the outpatient rehabilitation clinics of the Ninth People's Hospital of Shanghai Jiaotong University School of Medi-cine from January 2019 to February 2021.Under the design of a prospective controlled study,all patients were randomly divided into the posture training group(23 cases)and the control group(22 cases).The pos-ture training group received posture training for 3 weeks with 30 minutes each time;the control group only re-ceived health education.The patients in two groups received outpatient follow-up after 3 weeks.The maximum mouth opening(MMO)and pain intensity were measured before and after treatment,and the head rotation and craniovertebral angle were measured using the sagittal photograph. Result:The craniovertebral angle of the posture training group(n=22)after treatment were signifiicantly higher than the control group(n=20)(55.3°±2.3° vs 48.4°±4.4°,P＜0.001).The pain score in the posture training group was significantly lower than that in the control group(1.9±0.7 vs 2.9±0.8,P＜0.001).There were no sig-nificant group differences between the improvement of head rotation angle and MMO(P=0.437,P=0.313). Conclusion:Posture training can improve the head posture of myogenic and symptoms in TMD patients.
