ObjectiveTo evaluate the efficacy and safety of Xiaoji Hufei Formula in protecting children with close contact exposure to influenza， and to provide reference and evidence-based support for better clinical prevention and treatment of influenza in children. MethodsA multicenter， prospective， non-randomized， parallel， controlled trial was conducted from October 2021 to May 2022 in five hospitals， including Dongfang Hospital of Beijing University of Chinese Medicine. Confirmed influenza cases and influenza-like illness （ILI） cases were collected， and eligible children with close contact exposure to these cases were recruited in the outpatient clinics. According to whether the enrolled close contacts were willing to take Xiaoji Hufei formula for influenza prevention， they were assigned to the observation group （108 cases） or the control group （108 cases）. Follow-up visits were conducted on days 7 and 14 after enrollment. The primary outcomes were the incidence of ILI and the rate of laboratory-confirmed influenza. Secondary outcomes included traditional Chinese medicine （TCM） symptom score scale for influenza， influenza-related emergency （outpatient） visit rate， influenza hospitalization rate， and time to onset after exposure to influenza cases. ResultsA total of 216 participants were enrolled， with 108 in the observation group and 108 in the control group. Primary outcomes： （1） Incidence of ILI： The incidence was 12.0% （13/108） in the observation group and 23.1% （25/108） in the control group， with the observation group showing a significantly lower incidence （χ²=4.6， P<0.05）. （2） Influenza confirmation rate： 3.7% （4/108） in the observation group and 4.6% （5/108） in the control group， with no statistically significant difference. Secondary outcomes： （1） TCM symptom score scale： after onset， nasal congestion and runny nose scores differed significantly between the two groups （P<0.05）， while other symptoms such as fever， sore throat， and cough showed no significant differences. （2） Influenza-related emergency （outpatient） visit rate： 84.6% （11 cases） in the observation group and 96.0% （24 cases） in the control group， with no significant difference. （3） Time to onset after exposure： The median onset time after exposure to index patients was 7 days in the observation group and 4 days in the control group， with a statistically significant difference （P<0.05）. ConclusionIn previously healthy children exposed to infectious influenza cases under unprotected conditions， Xiaoji Hufei formula prophylaxis significantly reduced the incidence of ILI. Xiaoji Hufei Formula can be recommended as a specific preventive prescription for influenza in children.

Objective To investigate and evaluate the nutrition status in serum 25-hydroxy vitamin D[25(OH)D]levels of 0～12 years old children in Xi'an.Methods A total of 2 670 patients aged 0～12 years old who underwent routine physical examinations in Children's Health Department of the Second Hospital of Air Force Medical University were selected from March 2020 to July 2023,and the 25(OH)D data of these patients were conducted in retrospective analysis.The nutritional status of vitamin D in these children of different genders,ages and seasons were also analyzed.Results ①This study included 2 670 children aged 0～12 years old in Xi'an,with the average level of serum 25(OH)D was 40.80±18.00 ng/ml.Among them,38 cases(1.42%)had serum 25(OH)D deficiency,333 cases(12.47%)had serum 25(OH)D insufficience,and 2 299 cases(86.11%)had sufficient serum 25(OH)D.②There was a statistically significant difference in serum 25(OH)D levels among different age groups(H=1 524.23,P=0.000).The group aged 1～<4 has the highest value of 52.51±13.57 ng/ml,while the group aged 8～12 has the lowest value of 21.65±6.75 ng/ml.③The levels of serum 25(OH)D in summer(39.44±17.46 ng/ml)were lower than those in spring(41.96±17.76 ng/ml)and autumn(42.71±18.15 ng/ml),with statistical significant differences(Z=101.57,-134.06,all P<0.01).However,the deficiency and inadequate rate of serum 25(OH)D in winter(18.95%)was higher than those in spring,summer and autumn(13.52%,12.75%,12.36%),with statistical significant differences(χ2=14.32,P=0.026).④There was no statistically significant difference in serum 25(OH)D levels between genders(H=0.933,P=0.351).However,the deficiency and inadequate rate of serum 25(OH)D in boys(12.51%)was lower than that in girls(15.46%),and the difference was statistically significant(χ2=9.257,P=0.010).Conclusion The nutritional status of serum 25(OH)D in children aged 0～12 years in Xi'an area is comparatively fine,and it is necessary to strengthen the intake and supplementation of vitamin D in over 3 years old children.

ObjectiveTo investigate the effects of treadmill testing guided-rehabilitation exercises upon quality of life (QOL) of patients who underwent revascularization for coronary heart disease (CHD).Methods All the participants received routine therapy and rehabilitation for 6 weeks.A 36-item short-form (SF-36) was used to assess QOL of the patients.Results Injured functioning of patients who received revascularization for CHD were physiological function ( 37.86 ),social function ( 43.67 ),vitality (45.58),physical performance ( 65.45 ),mental health ( 68.73 ),role emotion ( 71.30 ),physical pain ( 79.52 ),and general health ( 86.75 ).After intervention,physiology function ( 37.86 ± 8.49 vs 62.13 ± 10.53 ),social function (43.67 ±26.23 vs 56.98 ± 18.89),vitality (45.58 ±27.01 vs 77.42 ±23.48),and physical pain (79.52 ±9.05 vs 87.32 ± 13.14) were significantly improved.Conclusion Rehabilitation exercises and behavioral psychological treatment may be beneficial to improve QOL of patients undergoing revascularization for CHD.

Objective To explore the value and criteria for primary tumor resection in patients with stage Ⅳ rectal cancer. Methods The clinical data were retrospectively analyzed for 53 patients with stage Ⅳ rectal cancer undergoing primary tumor resection. Results All patients were graded according to Eastern Cooperative Oncology Group (ECOG) performance as status 1. Seventeen of 53 patients (32%) received palliative resection. Thirty-six patients received adjuvant radiotherapy and/or chemotherapy. The median follow-up was 14 months. Forty-seven patients had complete resolution of their symptoms related to the primary rectal cancer for a year. The median survival was 16 months and 2-year overall survival of 24.5%. On multivariate analysis, chemotherapy was a determinant of prolonged survival (P=0.046). Conclusions Resection of primary tumor in patients with stage Ⅳ rectal cancer can improve the quality of life. Patients who have a good performance status, minimal metastatic disease and normal preoperative liver function tests should undergo resective surgery and aggresive systemic chemotherapy.
