Objective:To assess the clinical effectiveness and safety of Omalizumab for treating pediatric allergic asthma in real world in China.Methods:The clinical data of children aged 6 to 11 years with allergic asthma who received Omalizumab treatment in 17 hospitals in China between July 6, 2018 and September 30, 2020 were retrospectively analyzed.Such information as the demographic characteristics, allergic history, family history, total immunoglobulin E (IgE) levels, specific IgE levels, skin prick test, exhaled nitric oxide (FeNO) levels, eosinophil (EOS) counts, and comorbidities at baseline were collected.Descriptive analysis of the Omalizumab treatment mode was made, and the difference in the first dose, injection frequency and course of treatment between the Omalizumab treatment mode and the mode recommended in the instruction was investigated.Global Evaluation of Treatment Effectiveness (GETE) analysis was made after Omalizumab treatment.The moderate-to-severe asthma exacerbation rate, inhaled corticosteroid (ICS) dose, lung functions were compared before and after Omalizumab treatment.Changes in the Childhood Asthma Control Test (C-ACT) and Pediatric Asthma Quality of Life Questionnaire (PAQLQ) results from baseline to 4, 8, 12, 16, 24, and 52 weeks after Omalizumab treatment were studied.The commodity improvement was assessed.The adverse event (AE) and serious adverse event (SAE) were analyzed for the evaluation of Omalizumab treatment safety.The difference in the annual rate of moderate-to-severe asthma exacerbation and ICS reduction was investigated by using t test.The significance level was set to 0.05.Other parameters were all subject to descriptive analysis.A total of 200 allergic asthma patients were enrolled, including 75.5% ( n=151) males and 24.5% ( n=49) females.The patients aged (8.20±1.81) years. Results:The median total IgE level of the 200 patients was 513.5 (24.4-11 600.0) IU/mL.Their median treatment time with Omalizumab was 112 (1-666) days.Their first dose of Omalizumab was 300 (150-600) mg.Of the 200 cases, 114 cases (57.0%) followed the first Omalizumab dosage recommended in the instruction.After 4-6 months of Omalizumab treatment, 88.5% of the patients enrolled ( n=117) responded to Omalizumab.After 4 weeks of treatment with Omalizumab, asthma was well-controlled, with an increased C-ACT score [from (22.70±3.70) points to (18.90±3.74) points at baseline]. Four-six months after Omalizumab administration, the annual rate of moderate-to-severe asthma exacerbation had a reduction of (2.00±5.68) per patient year( t=4.702 5, P<0.001), the median ICS daily dose was lowered [0 (0-240) μg vs. 160 (50-4 000) μg at baseline] ( P<0.001), the PAQLQ score was improved [(154.90±8.57) points vs. (122.80±27.15) points at baseline], and the forced expiratory volume in one second % predicted (FEV 1%pred) was increased [(92.80±10.50)% vs. (89.70±18.17)% at baseline]. In patients with available evaluations for comorbidities, including allergic rhinitis, atopic dermatitis or eczema, urticaria, allergic conjunctivitis and sinusitis, 92.8%-100.0% showed improved symptoms.A total of 124 AE were reported in 58 (29.0%) of the 200 patients, and the annual incidence was 0(0-15.1) per patient year.In 53 patients who suffered AE, 44 patients (83.0%) and 9 patients (17.0%) reported mild and moderate AE, respectively.No severe AE were observed in patients.The annual incidence of SAE was 0(0-1.9) per patient year.Most common drug-related AE were abdominal pain (2 patients, 1.0%) and fever (2 patients, 1.0%). No patient withdrew Omalizumab due to AE. Conclusions:Omalizumab shows good effectiveness and safety for the treatment of asthma in children.It can reduce the moderate-to-severe asthma exacerbation rate, reduce the ICS dose, improve asthma control levels, and improve lung functions and quality of life of patients.

Objective:To investigate the epidemiological and clinical characteristics of human parainfluenza viruses (HPIVs) infection among hospitalized children with community-acquired pneumonia (CAP) in China, and provide basic data for diagnosis, treatment and prevention of HPIVs infection.Methods:From November 2014 to February 2020, 5 448 hospitalized children with CAP were enrolled in 14 hospitals in 11 provinces and municipalities directly under the Central Government in southern China and northern China. Nasopharyngeal aspirates or throat swabs were collected, and the nucleic acids of 18 types respiratory viruses including HPIV1-4 were screened by suspension array technology. Demographic data and clinical information were collected for statistical analysis.Results:The total detection rate of HPIVs in 5 448 children with CAP was 8.83% (481/5 448), and the detection rate in males was higher than that in females (62.79% vs. 37.21%; χ2=0.000, P=0.992). The detection rate of HPIVs in 1~< 3 years age group was higher than that in other age groups, and the difference was statistically significant ( χ2=61.893, P<0.001). The detection rate of HPIVs in the northern region was higher than that in the southern region (9.02% vs 8.65%), but the difference was not statistically significant ( χ2=0.239, P=0.625). The prevalence of HPIV1-4 in northern and southern China was not completely same. HPIV1 was mainly prevalent in autumn in both northern and southern regions. HPIV2 was prevalent in summer in northern China, and the detection rate was low in southern China. HPIV3 reached its peak in both spring and summer in both northern and southern China, but its duration was longer in southern China than in northern China. HPIV4 is mainly popular in autumn in both southern China and northern China. Among 481 children infected with HPIVs, 58.42% (281/481) were infected with HPIV alone, and the main clinical manifestations were cough (90.75%) and fever (68.68%). Out of the HPIV-positive cases, 42.62% (205/481) were co-infected with another type of HPIV or a different virus, while 11.43% (55/481) had co-infections with two or more different viruses. HPIV3 was the most common type of co-infection with other viruses. HPIV3 infection accounted for the largest proportion (76.80%) in 47 HPIVs-positive children with severe pneumonia. Conclusions:HPIVs is one of the most important pathogens causing CAP in children in China, and children under 3 years of age are the main populations of HPIVs infection. The prevalence characteristics of all types of HPIVs in children in the north and south are not completely same. HPIV3 is the dominant type of HPIV infections and causes more severe diseases.

Acute respiratory tract infection is the most common infectious disease in children, which seriously threatens children′s health.Rapid and accurate etiological diagnosis is of great significance for the clinical treatment and control of these diseases.Pathogen nucleic acid test was applied and became the main method of respiratory tract infection diagnosis for its high sensitivity and specificity.To regulate the application of pathogen nucleic acid amplification test in respiratory tract infection in children, improve the diagnosis level, expert consensus on nucleic acid amplification test of respiratory pathogens in children was prepared to guide the application and promote pathogens diagnosis ability.

Monkeypox is a zoonotic disease.Previous studies have shown that children are vulnerable to monkeypox and are also at high risk for severe disease or complications.In order to improve pediatricians′ understanding of monkeypox and achieve early detection, early diagnosis, early treatment and early disposal, the committee composed of more than 40 experts in the related fields of infectious diseases, pediatrics, infection control and public health formulate this expert consensus, on the basis of the latest clinical management and infection prevention and control for monkeypox released by the World Health Organization (WHO), the guidelines for diagnosis and treatment of monkeypox (version 2022) issued by National Health Commission of the People′s Republic of China and other relevant documents.During the development of this consensus, multidisciplinary experts have repeatedly demonstrated the etiology, epidemiology, transmission, clinical manifestations, laboratory examinations, diagnosis and differential diagnosis, treatment, discharge criteria, prevention, case management process and key points of prevention and control about monkeypox.

Group A Streptococcus (GAS) is a very important pathogen, especially for children.On a global scale, GAS is an important cause of morbidity and mortality.But the burden of disease caused by GAS is still unknown in China and also has not obtained enough attention.For this purpose, the expert consensus is comprehensively described in diagnosis, treatment and prevention of GAS diseases in children, covering related aspects of pneumology, infectiology, immunology, microbiology, cardiology, nephrology, critical care medicine and preventive medicine.Accordingly, the consensus document was intended to improve management strategies of GAS disease in Chinese children.

Objective:To explore the classification of the therapeutic effect of patients with high-risk differentiated thyroid carcinoma (DTC) after surgery and 131I treatment, and to analyze the relevant factors that affect the therapeutic effect. Methods:From January 2015 to January 2018, 256 high-risk DTC patients (70 males, 186 females; age (47.6±12.9) years) in the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. According to the 2015 American Thyroid Association(ATA)guidelines for therapeutic effect classification standards and the data measured during 6 months postoperative stimulation state, patients were divided into excellent response (ER) group, inderterminate response (IDR) group, biochemical incomplete response (BIR) group and structurally incomplete response (SIR) group, and the latter two groups were further combined into incomplete response (IR) group. χ2 test, Fisher exact test and Kruskal-Wallis rank sum test were used to compare the clinical characteristics among the four groups. The receiver operating characteristic (ROC) curve of the relationship with ER and IR was established. Multivariate logistic regression was used to analyze the independent influencing factors of ER and IR. The subgroups with B-Raf proto-oncogene, serine/threonine kinase (BRAF) V006E results were individually tested with χ2 test of therapeutic efficacy. Results:There were 48.05%(123/256), 20.31%(52/256), 19.53%(50/256) and 12.11%(31/256) of DTC patients in ER, IDR, BIR and SIR groups respectively. The differences in gender ( χ2=11.495, P=0.008), tumor size ( H=21.368, P<0.001), N stage ( χ2=42.012, P<0.001), distant metastasis ( P<0.001) and pre-ablation stimulated thyroglobulin (psTg) level ( H=142.829, P<0.001) were statistically significant among the 4 groups. The cut-off values of psTg for predicting ER and IR were 5.38 μg/L and 15.85 μg/L with the sensitivities of 79.7%(98/123) and 88.9%(72/81), with the specificities of 84.2%(112/133) and 91.4%(160/175) respectively. The cut-off values of tumor size for predicting ER and IR were 1.45 cm and 1.95 cm with the sensitivities of 63.4%(78/123) and 53.1%(43/81), with the specificities of 66.2%(88/133) and 74.3%(130/175) respectively. Multivariate regression analysis showed that female (odds ratio ( OR)=2.305, 95% CI: 1.041-5.104), N0 stage ( OR=2.365, 95% CI: 1.104-5.066), psTg<5.38 μg/L ( OR=17.271, 95% CI: 8.561-34.841) and tumor size <1.5 cm ( OR=2.194, 95% CI: 1.092-4.409) were independent predictors of ER; psTg≥15.85 μg/L ( OR=81.544, 95% CI: 30.561-217.577), N1b stage ( OR=3.617, 95% CI: 1.276-10.253) and tumor size >4.0 cm( OR=47.060, 95% CI: 2.449-904.360) were independent predictors of IR. The BRAF V006E mutation rate of patients in the distant metastasis subgroup of the SIR group was significantly lower than that in ER, IDR, and BIR groups ( χ2 values: 20.852-40.905, all P<0.008). Conclusions:About 48.05% of high-risk patients can achieve ER half a year after the initial treatment and be classified as low-risk again. Female, patients with N0 stage, psTg<5.38 μg/L and tumor size <1.5 cm have better therapeutic effect after initial treatment; patients with N1b stage, psTg≥15.85 μg/L and tumor size >4.0 cm have poor therapeutic effect after initial treatment.

Objective:To screen the factors that were conducive to prolonging the effective half-life of 131I, and to provide a basis for selecting more suitable patients for the treatment of hyperthyroidism with lithium carbonate assisted radioactive 131I. Methods:Between July 2017 and March 2019, a total of 61 patients (23 males, 38 females, age: 13-73 (37.7±1.9) years) who received lithium carbonate adjuvant therapy before 131I treatment in the First Affiliated Hospital of Zhengzhou University were collected into this prospective study. Clinical parameters (serum free triiodothyronine (FT 3), serum free thyroxine (FT 4), iodine uptake rate (2 h, 12 h, 24 h) and ratio of iodine uptake rate (2 h/24 h, 4 h/24 h) before and after taking lithium carbonate were compared by using paired t test. The factors which were conducive to prolonging the effective half-life of 131I were analyzed by linear and multiple regression analyses. Results:Compared with the pretreatment results, lithium carbonate treatment significantly improved the 24 h iodine uptake rate ((74.82±2.69)% vs (82.38±2.33)%; t=2.674, P=0.010), decreased the ratio of 4 h/24 h iodine uptake rate ((88.96±2.85)% vs (82.12±2.27)%; t=2.644, P=0.010), prolonged the effective half-life of 131I ((123.03±3.09) vs (130.38±2.49) h; t=2.656, P=0.010), and decreased serum FT 3 ((26.46±1.65) vs (21.31±1.42) pmol/L; t=3.421, P=0.001) and serum FT 4 ((56.59±2.12) vs (49.24±2.19) pmol/L; t=3.289, P=0.002). Linear regression analysis showed that 2 h and 4 h iodine uptake rate, the ratios of 2 h/24 h and 4 h/24 h iodine uptake rate, and effective half-life of 131I before lithium carbonate treatment were related to the effective half-life of 131I after lithium carbonate treatment ( b values: from -0.576 to 0.642, all P<0.05). Multiple linear regression analysis showed that the ratio of 4 h/24 h iodine uptake rate was the main factor affecting the effective half-life of 131I after taking lithium carbonate ( b=0.642, 95% CI: 0.453-0.832, P<0.001). Multiple linear regression equation was y=-49.785+ 0.642 x. Lithium carbonate treatment could prolong the effective half-life of 131I if the ratio of 4 h/24 h iodine uptake exceeded 77.55%. Conclusion:The ratio of 4 h/24 h iodine uptake rate is the main factor affecting the change of the effective half-life of 131I after lithium carbonate treatment, and patients with hyperthyroidism whose ratio of 4 h/24 h iodine uptake rate exceeds 77.55% can effectively prolong the effective half-life of 131I after taking lithium carbonate.

Liver fibrosis, a common pathological process of most types of chronic liver diseases, is caused by the excessive deposition of extracellular matrix proteins after chronic liver injury. An increasing number of evidence has shown that oxidative stress is closely associated with the development and progression of liver fibrosis and is involved in the pathological process of liver fibrosis caused by various factors. With natural constituents and a clear structure, Chinese herbal monomers herbs have achieved a marked clinical effect in the treatment of liver fibrosis. This article reviews the research advances in monomers of Chinese herbs in the treatment of liver fibrosis by regulating oxidative stress-related signaling pathways.
