Progress and prospect of inhaled biological agents in asthma / 中国临床药理学与治疗学

More than 300 million people worldwide suffer from asthma, and the incidence is increasing year by year. As one of the most common chronic diseases, asthma is an immune-mediated inflammatory disease with complex triggering mechanisms and strong heterogeneity. With the in-depth study of physiological and pathological mechanisms, therapeutic small molecule and hormone drugs have been introduced to control and treat most patients, but about 5% - 10% of patients still suffer from various subtypes of difficult to control and treat asthma, that is, severe asthma. In the past decade, with the rapid development of bio-pharmaceutical research, protein and antibody have become the key drugs for the treatment of severe asthma with high efficacy, high specificity and high safety. However, biological drugs are usually administered by injection, they cannot be noninvasive and directly delivered into the lung to quickly absorb and take effect. Therefore, there is an urgent need for the introduction of inhaled biologics with quick effectiveness, convenience, economy and safety in clinical. The review summarizes the existing small molecule, hormone and biological therapy drugs, and summarizes the development of inhalable biological agents of asthma, and analyzes the future prospects of the inhalable biological drugs, which is designed to deepen the perception of the direction of the inhalable biological drugs research, and update the information of the field, in order to provide reference for the development of more inhalable biologics.

A new form of familial platelet disorder caused by germline mutations in RUNX1 in a pedigree / 中华内科杂志

Objective: To investigate the clinical and biological characteristics of familial platelet disorder (FPD) with germline Runt-related transcription factor (RUNX) 1 mutations. Methods: Patients diagnosed with myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) with RUNX1 mutations from February 2016 to December 2021 in Wuhan No.1 Hospital underwent pedigree analysis and were screened for gene mutations (somatic and germline). Patients diagnosed with FPD with germline RUNX1 mutations were enrolled and evaluated in terms of clinical characteristics and biological evolution. Bioinformatics analysis was used to assess the pathogenicity of mutations and to analyze the effect of mutated genes on the function of the corresponding protein. Results: Germline RUNX1 mutations were detected in three out of 34 patients suffering from MDS/AML who had RUNX1 mutations. A pedigree of FPD with RUNX1 (RUNX1-FPD) c.562A>C and RUNX1 c.1415T>C mutations was diagnosed, and the mutations were of patrilineal origin. Bioinformatics analysis indicated that the locus at positions 188 and 472 in the AML-1G type of RUNX1 was highly conserved across different species, and that variations might influence functions of the proteins. The mutations were evaluated to be highly pathogenic. Of the nine cases with germline RUNX1 mutations: two patients died due AML progression; one case with AML survived without leukemia after transplantation of hemopoietic stem cells; four patients showed mild-to-moderate thrombocytopenia; two cases had no thrombocytopenia. During the disease course of the proband and her son, mutations in RUNX1, NRAS and/or CEBPA and KIT appeared in succession, and expression of cluster of differentiation-7 on tumor cells was enhanced gradually. None of the gene mutations correlated with the tumor were detected in the four cases not suffering from MDS/AML, and they survived until the end of follow-up. Conclusions: RUNX1-FPD was rare. The mutations c.562A>C and c.1415T>C of RUNX1 could be the disease-causing genes for the family with RUNX1-FPD, and these mutations could promote malignant transformation. Biological monitoring should be carried out regularly to aid early intervention for family members with RUNX1-FPD.

Objective: To understand and analyze the incidence of club drug abuse and influencing factors in men who have sex with men (MSM) in Qingdao, and provide reference for the AIDS prevention and intervention in this population. Methods: From March 2017 to July 31, 2022, MSM who did not abuse club drug were recruited by snowball sampling of MSM social organizations in Qingdao, a prospective cohort was established, and a follow-up survey was conducted every 6 months. The survey collected the information about the MSM's demographic characteristics, sexual characteristics, club drug abuse and others. The incidence of club drug abuse was the outcome dependent variable and the interval between the recruitment into the cohort and the incidence of club drug abuse was the time dependent variable. Cox regression analysis was conducted to identify the influencing factors for club drug abuse. Results: A total of 509 MSM were recruited at baseline survey, and 369 eligible MSM were enrolled in this cohort. A total of 62 MSM began to abuse club drug during the study period, and the cumulative follow-up time was 911.54 person-years, the incidence of club drug abuse was 6.80/100 person-years. All the club drug abusers shared drugs with others in the first club drug abuse, and 16.13% (10/62) had mix-use of club drugs. The multivariate Cox proportional risk regression analysis showed that being students (aHR=2.17, 95%CI: 1.15-4.10), receiving no HIV testing or receiving 1 HIV testing during past 6 months (aHR=4.57, 95%CI:1.80-11.60; aHR=5.15, 95%CI: 2.83-9.36), having sex only with regular sexual partners during past 6 months (aHR=4.75,95%CI:2.32-9.75), having more than 4 homosexual partners (aHR=1.70, 95%CI:1.01-2.87) and abuse of club drug of sexual partners during past 6 months (aHR=12.78, 95%CI:3.06-53.35) were significantly associated with club drug abuse in the MSM. Conclusions: The incidence of club drug abuse was at a high level in the MSM cohort in Qingdao, indicating a high risk for HIV infection. Being student, receiving less HIV testing, having sex only with regular sexual partners, having more homosexual partners and abuse of club drug of sexual partners during past 6 months were risk factors for the incidence of club drug abuse in the MSM. Targeted surveillance and intervention measures should be strengthened to reduce the risk of club drug abuse in MSM.

Aim To study the antitumor effect of cispl-atin ( DDP) chemotherapy promoted by Taohong Siwu Decoction (TSD) on mice with lung adenocarcinoma mice. Methods Lewis lung carcinoma cell line was used to make homologous lung adenocarcinoma trans¬plantation mouse model. Normal control, Model, TSD, DDP, TSD + DDP groups were set up. The change of transplanted tumor volume after administration was observed, the weight of transplanted tumor was weighed, the expression of Ki67 in transplanted tumor tissue was detected by immunohistochemistry, TUNEL was detected by fluorescence staining, Bcl-2, Bax, cleaved Caspase-3 and cleaved Caspase-9 were detected by immunoblotting, and the content of D-dirtier in plasma was measured by ELISA. Results DDP plus TSD significantly inhibited the growth of transplanted tumor. Ki67 expression in tumor tissue was lower than that in DDP group (28. 3% ±3. 1% vs 40. 3% ±2.1% ). The combined use of TSD and DDP significantly promoted the apoptosis level of transplanted tumor. The positive rate of TUNEL was significantly higher than that of DDP group (41. 0% ±3.0% vs 30.7% ± 4.5%). Bax, cleaved Caspase-3 and cleaved Caspase-9 expressions in tumor tissue were also higher than those of DDP group, while the expression of Bcl-2 was significantly lower than that of DDP group. Moreover, we found a significant interaction between TSD and DDP on the expression of four apoptotic proteins ( P < 0.05 ) . The plasma D-dimer content in TSD + DDP group was significantly lower than that in DDP group (188. 50 ± 28. 46 vs 269.80 ± 35.92) μg • L

Mechanism of regulating immune dysfunction of sepsis based on network pharmacology and experimental verification / 中国药理学通报

Aim To verify the role of Shengjiang Powder in sepsis and explore its molecular mechanism. Methods The targets of drug active ingredients and disease-related targets were searched by TCMSP, Disgenet and other databases, and the intersection of the two was selected. DAVID database was used to carry out enrichment analysis of GO and KEGG pathways for intersection targets, and molecular docking was performed between drug active ingredients and core genes of key pathways. Mouse model of sepsis was constructed by cecal ligation puncture (CLP). Spleen tissue and serum of mice were collected. The percentage of T cell subsets in spleen was detected by flow cytometry, and IL-6 and IL-10 levels in serum were detected by ELISA. Results A total of 25 active ingredients, 238 targets of active ingredients, 2797 disease-related targets, 90 genes of intersection between active ingredients and disease-related targets, potential targets were AKT, JUN, EGFR, MMP9, etc. GO enrichment analysis showed 1021 items, including 942 biological processes, 23 cell compositions and 55 molecular functions. KEGG pathway analysis found that the intersection genes were mainly enriched in THE PD-1/PD-L1 signaling pathway, HIF-1 signaling pathway, TNF signaling pathway and inflammatory mediators signaling pathway, indicating that the therapeutic effect may be related to these pathways. The molecular docking results showed that quercetin, kamanol, emodin and other core compounds could be well combined with key genes. Flow cytometry results showed that after seven days of CLP, the proportion of CD4 T cells in spleen decreased, the proportion of CD4 PD-1 T cells increased, the release of IL-6 decreased, the content of IL-10 increased, and the mice were immunosuppressed. The percentage of CD4 T cells in spleen increased, the number of CD4 PD-1 T cells decreased, the release of IL-6 was enhanced, the content of IL-10 decreased, and the immunosuppression was improved. Conclusions It is proved that Shengjiang Powder can increase the release of pro-inflammatory cytokine IL-6, increase the ratio of CD4 T/CD8 T cells, and decrease the expression of anti-inflammatory cytokine IL-10 in the late stage of sepsis, so as to improve immune suppression in the late stage of sepsis and improve the survival rate of mice.

The Hammersmith Infant Neurological Examination for following-up the gross motor development of high-risk infants / 中华物理医学与康复杂志

Objective:To explore the ability of the Hammersmith Infant Neurological Examination (HINE) to predict the gross motor development of high-risk infants.Methods:A total of 207 high-risk infants were assessed with the HINE and the Gesell Developmental Schedule (GDS) at the ages of 3, 6, 9 and 12 months. They were then divided into a normal development group and a delayed group according to their gross motor development at 12 months old. The validity of the HINE′s discrimination was quantified retrospectively as the difference in the total HINE score at each follow-up month between the two groups. Spearman coefficients relating the total HINE score with the gross motor development quotient from the GDS were calculated at each follow-up month. The HINE′s total score threshold for predicting gross motor retardation at 12 months was determined from a receiver operating characteristics curve, and the predictive validity, sensitivity and specificity were evaluated by calculating the area under the curve.Results:At each time point the average total HINE score of the delayed group was significantly lower than the normal group′s average. The correlation between the HINE total scores and the GDS gross motor development quotients was strongest at 6 months old, and weakest at 3 months. The threshold total HINE score for predicting gross motor retardation at 12 months old was 60 at 3 months, 67 at 6 months, and then 71. The instrument′s sensitivity and specificity were very good at all four time points.Conclusion:The HINE can usefully predict gross motor retardation in the first year of life for high-risk infants. The critical value of the total score can be used as an auxiliary diagnostic reference for neuromotor development in such infants.
