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.

The percentages of Th17 cells, IL-17 and IL-6 levels in peripheral blood of the HSP-MP group was significantly higher than those in the other three groups( P<0.05), which in HSP group and MP group were higher than that in control group( P<0.05). There was no statistical difference between HSP group and MP group( P>0.05). The percentage of Treg cells in peripheral blood was significantly lower in HSP-MP group than those in the other three groups( P<0.05), which in the HSP group and MP group were lower than those in control group( P<0.05). There was no statistical difference between HSP group and MP group( P>0.05). There were no statistically significant differences of TGF-β among the four groups( P>0.05). Conclusion:High levels of IL-17 and IL-6 may be an important factor causing severe Th17/Treg immune disorders in children with HSP combined with MP infection, which may play an important role in the pathogenesis of HSP combined with MP infection.

A case-control study on the effect of food allergies on childhood asthma / 公共卫生与预防医学

Objective To analyze the effects of food allergies on asthma in children over 6 years old in Zhongshan. Methods A case-control study was designed. 279 children over 6 years old with asthma diagnosed in Boai Hospital of Zhongshan were enrolled as the case group, and 980 children without asthma from primary school were enrolled as the control group. The food allergy exposure, other related risk factors, and food allergy characteristics of the two groups were retrospectively analyzed. Logistic regression was used to analyze the OR values ​​of each factor. Results The asthma children's food allergy, family asthma history, family medicine and food allergy history, artificial feeding, adding beef and mutton or seafood before the age of one year, and frequent consumption of puffed foods such as shrimp chips were significantly higher than those of non-asthmatic children. Using multivariate logistic regression analysis, food allergy (OR=3.143, P<0.001), artificial feeding (OR=3.045, P<0.001), family history of asthma (OR=2.250, P<0.001) remained significantly in the multivariate model. For food allergies, children with asthma had more types of food allergies than children without asthma (P<0.001), and had a higher proportion of allergies to milk and eggs (P<0.001). There were higher proportion of introduction of beef and mutton and seafood before 1 year old (P<0.001), and higher proportion of frequently consuming puffed foods (P<0.001) in children with asthma than children without asthma, while the rate of desensitization treatment was lower (P<0.001). Conclusion Food allergy may be an independent risk factor for asthma. Children with asthma had a variety of allergies associated with food allergies. Desensitization treatment for food allergies may reduce the risk of asthma.

Surveillance of antimicrobial resistance in the Streptococcus pneumoniae strains isolated from respiratory tract of children / 中国感染与化疗杂志

Objective To investigate the antimicrobial resistance profile of the Streptococcus pneumoniae strains isolated from respiratory tract of children in Zhongshan Boai Hospital, Guangdong Province for better management of such infections. Methods The sputum samples were collected from respiratory tract of children in pediatric outpatient and inpatient from May 2013 to August 2017. S. pneumoniae strains were isolated and identified and their susceptibility to antimicrobial agentswas determined. Results The prevalence of S. pneumoniae was 10.6％ (2 963/28 006) in the sputum samples. S. pneumoniae was mainly isolated from children under 6 years old, and relatively higher in winter and spring. About 43.0％ of the S. pneumoniae isolates was associated with mixed infection, especially Moraxella catarrhalis and Haemophilus influenzae. About 6.0％ of the S. pneumoniae isolates were non-susceptible to penicillin, 59.3％ non-susceptible to ceftriaxone, and more than 95％ non-susceptible to erythromycin, clindamycin or tetracycline. However, more than 95％ of the isolates were susceptible to chloramphenicol or ofloxacin. No S. pneumoniae isolate was found resistant to rifampin, linezolid or vancomycin. Conclusions The respiratory tract infection caused by S. pneumoniae of children is increasing year by year, which is associated with age, season, and higher rate of mixed infection. These data showed that penicillin non-susceptible S. pneumoniae is highly prevalent in Zhongshan. More than 95％ of the S. pneumoniae isolates from children are resistant to erythromycin, clindamycin or tetracycline. S. pneumoniae isolates should be closely monitored for the emergence of multidrug resistant strains. Appropriate control measures must be taken according to the results of susceptibility testing.

The levels of progesterone (16.20 ± 2.49 ng/ml vs. 27.61 ± 2.97 ng/ml, t=-2.378), orphanin (9.94 ± 2.03 ng/L vs. 15.62 ± 3.38 ng/L, t=-2.137), EPDS score (7.7 ± 2.4 vs. 11.6 ± 4.2, t=-2.449) in the treatment group were significantly lower than those in the control group (P<0.05). While the estradiol (231.93 ± 8.25 pg/ml vs. 197.46 ± 8.72 pg/ml, t=-2.273), 5-hydroxytryptamine (1.90 ± 0.36 μmol/L vs. 1.39 ± 0.27 μmol/L, t=-2.016) in the treatment group were significantly higher than those in the control group (P<0.05). Conclusions The Yangxue-Shugan decoction and psychological intervention in the treatment of postpartum depression can improve the depression status of postpartum depression patients, reduce clinical symptoms and improve clinical efficacy.

Studying the Effect of Downregulating Autophagy-Related Gene LC3 on TLR3 Apoptotic Pathway Mediated by dsRNA in Hepatocellular Carcinoma Cells / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: The purpose of this study is to examine the role of the double-stranded RNA (dsRNA) activated Toll–interleukin-1 receptor domain-containing adaptor inducing interferon β (TRIF) signal pathway in triggering apoptosis in hepatocellular carcinoma (HCC) cells. MATERIALS AND METHODS: First, siRNA targeted autophagy–related gene LC3 (pU6H1-LC3 siRNA and siLC3) and a dsRNA used as a Toll-like receptor 3 (TLR3) ligand was constructed and synthesized, respectively. Then, a human HCC cell line was transfected with dsRNA, siLC3, and cotransfected with siLC3 and dsRNA (siLC3+dsRNA), respectively. Finally, quantification real-time polymerase chain reaction, western blotting, and immunofluorescence staining were used in the HCC line (SMMC7721), and MTT assay, flow cytometry, terminal deoxynucleotidyl transferase-mediated dUTP nick-end-labeling, and transmission electron microscopy were used in an HCC xenograft model of nude mice. Human umbilical vein endothelial cell tube forming assay, color Doppler ultrasonographic flow image examination, and CD34-positive microvessel density were used in vitro and in vivo. RESULTS: Compared with untreated cells, the protein and mRNA expression of TLR3 and TRIF was up-regulated, in order, siLC3+dsRNA, dsRNA, and siLC3. Expression of LC3 was obviously down-regulated and the autophagosomes were significantly decreased in siLC3+dsRNA and siLC3, whereas in dsRNA (p < 0.05). LC3 and TRIF colocation was observed in HepG2 cells. Decreased cell viability, increased apoptosis, decrease in xenograft tumor volume, and angiogenesis potential were also observed in order (p < 0.05). CONCLUSION: Suppression of intracellular autophagy resulted in decreased degradation of TRIF protein, which can promote triggering of apoptosis by the TLR3-TRIF pathway. dsRNA and siLC3 could play anticancer roles in coordination.

Interference of IL-4RA transfection to express level of STAT6 in airways / 中国免疫学杂志

Objective:To study the effect of airway IL-4RA gene transfer on asthma-associated expression of STAT6 in the mice of allergic asthma.Methods:Forty BALB/c mice were randomly divided into four groups:blank control,asthma model,asthma model administered by pLNC-laz,and asthma model administered by glucocorticoid and pLNC-IL-4RA.The ten mice in each groups were sensitized by i.p.injection of 10 ?g of OVA emulsified in 40 mg of aluminum hydroxide in a total volume of 200 ?l on the days of 1st,7th and 14th.On the 15th day,the mice were challenged via airways with OVA for 7 days,20 min a day,blank control were sensitized by i.p.injection of 200 ?l pH=7.4 PBS on days 7 and 14.Asthma model was administered by pLNC-laz or pLNC-IL-4RA for 3 days beginning at the 12th day.The mice of the group with glucocorticoid was administered with glucocorticoid on the 15th day for 7 days.24 hours after the last challenge,the mice were sacrificed by bloodletting.Serum OVA-specific IgE and blood Eosinophils were measured.The lungs were fixed by immersion in 10% formalin.Expression of STAT6 was identified by immunohistochemistry.Results:It was shown that pLNC-IL-4RA was integrated to the genomic DNA of pneumonic tissues.Retrovirus-mediated delivery of IL-4RA to airways of the asthma mice weakened airway eosinophilia triggered by either IL-13 or IL-4.Furthermore,IL-4RA delivered by retrovirus was expressed in airways of the mice with allergen sensitization,resulting in significiant reduction of expressing level of asthma-associated STAT6 in the experimental mice of allergic asthma.Conclusion:Retrovirus mediated delivery of IL-4RA to airways reduces expression of STAT6 in pneumonic tissues of asthmatic mice.Thus,the gene theraphy can be a potential therapeutic option to treat and control chronic airway inflammation and asthmatic symptoms.

Expression of p63?PCNA and EGFr in Skin Squamous Cell Carcinoma / 中华皮肤科杂志

Objective To investigate expression of p63?PCNA and epidermal growth factor receptor(EGFr)in skin squamous cell carcinoma(SCC) . Method Tissue specimens from 68 cases of SCC were studied using immunohistochemistry staining method with monoclonal antibodies to p63?PCNA and EGFr. Results The expression of p63 protein and PCNA was principally restricted to basal cells with high proliferative potentiality and was absent in cells of stratum corneum that were undergoing terminal differentiation in normal or carcinoma epidermis. In highly differentiated tumors, the staining of p63 formed a ring surrounding carcinoma nests. In low differentiated tumors, p63 positive cells were increased and disorderly arranged. Diffuse expression of PCNA and EGFr was found through out all carcinoma nests. Expression of p63?PCNA and EGFr was significantly stronger in SCC and intraepithelial neoplasm(SIN)level Ⅲthan those in normal or proliferative epidermis near the carcinoma. A significant correlation was found between expression of p63,PCNA,EGFr and degree of differentiation of SCC,and between p63 and EGFr,p63 and PCNA,PCNA and EGFr, respectively. Conclusion Overexpression of p63?PCNA?EGFr may be contributed to acquisition of enhanced capability of proliferation, aggression and anaplasia in SCC.

Expression of Matrix Metalloproteinases and C-myc in Cutaneous Squamous Cell Carcinoma / 中华皮肤科杂志

Objective To investigate the expression of matrix metalloproteinases(MMP) related to oncogene C-myc and tumor differentiation of cutaneous squamous cell carcinoma (CSCC). Methods Expression of MMP2,MMP9 and C-myc was detected by immunohistochemistry in 68 paraffin embedded specimens of CSCC. Results Distribution of MMP2 and MMP9 was demonstrated within cytoplasm of tumor and stromal cells, especially for those cells at the interface of tumor and interstitial tissues. No expression of MMP2 and MMP9 was observed in the horny centers of tumor cell nests. Expression of MMP2 and MMP9 increased along with the decreasing of the differentiation of tumor tissue and the increasing of C-myc expression. Conclusions Expression of MMP2 and MMP9 might be a common event for both tumor and stromal cells but parenchymal tumor cells might predominate over the activation of MMP2 and MMP9. Oncogene C-myc protein might promote the secretion of MMP2 and MMP9 by tumor cells.
