Allergic asthma is a complex,polygenic disease characterized by chronic inflammation and airway hyperresponsiveness. Fungus and dust mites are the most important inhaled allergens of allergic asthma,and often exist in the form of mixed allergens. In recent years,genetic studies have shown that several genes are associated with allergic asthma attacks. This article reviews the studies on the genes related to allergic asthma caused by dust mites and fungus,such as a disintegrin and metalloproteinase 33(ADAM33),interleukin-4(IL-4),glycoprotein A repetitions predominant(GARP),toll like receptor 3(TLR3),mannose-binding lectin 2(MBL2),chemokine(C-C motif)ligand 17(CCL17)and other genes .

Objective:
To reveal the molecular mechanism underlying the compatibility of Salvia miltiorrhiza Bge (S. miltiorrhiza, Dan Shen) and C. tinctorius L. (C. tinctorius, Hong Hua) as an herb pair through network pharmacology and subsequent experimental validation.
Methods:
Network pharmacology was applied to construct an active ingredient-efficacy target-disease protein network to reveal the unique regulation pattern of S. miltiorrhiza and C. tinctorius as herb pair. Molecular docking was used to verify the binding of the components of these herbs and their potential targets. An H9c2 glucose hypoxia model was used to evaluate the efficacy of the components and their synergistic effects, which were evaluated using the combination index. Western blot was performed to detect the protein expression of these targets.
Results:
Network pharmacology analysis revealed 5 pathways and 8 core targets of S. miltiorrhiza and C. tinctorius in myocardial protection. Five of the core targets were enriched in the hypoxia-inducible factor-1 (HIF-1) signaling pathway. S. miltiorrhiza-C. tinctorius achieved vascular tone mainly by regulating the target genes of the HIF-1 pathway. As an upstream gene of the HIF-1 pathway, STAT3 can be activated by the active ingredients cryptotanshinone (Ctan), salvianolic acid B (Sal. B), and myricetin (Myric). Cell experiments revealed that Myric, Sal. B, and Ctan also exhibited synergistic myocardial protective activity. Molecular docking verified the strong binding of Myric, Sal. B, and Ctan to STAT3. Western blot further showed that the active ingredients synergistically upregulated the protein expression of STAT3.
Conclusion
The pharmacodynamic transmission analysis revealed that the active ingredients of S. miltiorrhiza and C. tinctorius can synergistically resist ischemia through various targets and pathways. This study provides a methodological reference for interpreting traditional Chinese medicine compatibility.

In 2016, a national one million general population cohort project was set up in China for the first time in "Precision Medicine Research" Key Project, National Key Research and Development Program of China, which consists of general population cohorts in seven areas in China. As one of the seven major areas in China, northeastern China has unique climate and specific dietary patterns, and population aging is serious in this area. And the burden of chronic and non-communicable diseases ranks tops in China. Therefore, it is of great significance to establish a large general population cohort in northeastern China to explore the area specific exposure factors related to pathogenesis and prognosis of chronic and non-communicable diseases, develop new prevention strategies to reduce the burden of the diseases and improve the population health in northeastern China. In July 2018, the general population cohort study in northeastern China was launched, the study includes questionnaire survey, health examination and blood, urine and stool sample collection and detection in recruited participants. By now, the cohort has covered all age groups, and the baseline data of 115 414 persons have been collected. This paper summarizes the design and practice of the general population cohort study in northeastern China to provide reference for related research in China.

Objective:To evaluate the antibacterial efficacy of ceftobiprole, vancomycin, linezolid, and daptomycin against Staphylococcus aureus (SAU) and coagulase-negative Staphylococcus (CNS) bloodstream infections, which can provide a reference for clinical medication. Methods:A total of 1 777 strains of staphylococci were isolated from blood culture of 51 hospitals within the Blood Bacterial Resistant Investigation Collaborative System (BRICS) from January to December in 2021. The dilution method was used to assess the minimum inhibitory concentrations (MIC) of ceftobiprole, vancomycin, linezolid and daptomycin on staphylococci. Additionally, the probability of target attainment (PTA) and cumulative fraction of response (CFR) of these medications in varied dosage regimens were predicted using Monte Carlo simulation.Results:Ceftobiprole demonstrated significant antibacterial activity against methicillin-resistant Staphylococcus aureus(MRSA), the MIC 50 and MIC 90 were 0.500 and 1.000 mg/L, respectively, and the MIC range was ≤0.060 to 4.000 mg/L.Meanwhile, the ceftobiprole-resistance rate of SAU was 0.1%(1/1 073), but the resistance rate of CNS was 7.7%(54/704). There was no evidence of staphylococcal resistance to daptomycin or vancomycin. Against methicillin-sensitive Staphylococcus aureus (MSSA), no resistance to the four drugs was observed. Monte Carlo simulation showed that standard drug regimens of ceftobiprole (500 mg once every eight hours) and daptomycin (6 mg·kg -1·d -1) achieved high PTA and CFR against staphylococcus.The current vancomycin and linezolid standard treatment for staphylococcal bloodstream infections had a low CFR. When vancomycin 1 000 mg once every eight hours was used, the CFRs of MRSA and MSSA were both≥90.0%, while the CFR of CNS was still less than 80.0%. CFR of linezolid against staphylococcus was ≥90.0% under the dosages of 600 mg once every eight hours. Conclusions:Ceftobiprole, vancomycin, linezolid and daptomycin all show strong antibacterial activity against staphylococcus.Ceftobiprole and daptomycin standard treatment represent adequate antibacterial efficacy against staphylococcal bloodstream infections. Furthermore, appropriate increase of the dosages of vancomycin and linezolid based on the MIC value and species of bacteria is necessary.

Objective To establish and improve the quality standard of ginkgo semen decoction pieces. Methods The morphological character for 29 batches of ginkgo gemen and 12 batches of stir-fried ginkgo gemen were observed, and the moisture contents were assayed using the method in Chinese Pharmacopoeia 2015 edition, the first supplement. Results The character of ginkgo gemen and stir-fried ginkgo gemen were consistent in different batches. The moisture content of ginkgo gemen was 8.8% to 12.2%, with an average of 10.5%. The moisture content of stir-fried ginkgo gemen was from 5.4% to 12.3%, with an average of 8.9%. Considering that ginkgo semen decoction pieces are stored for a long time, they are prone to the attack of mildew and insects, and the moisture limit is set to be no more than 10.0% in ginkgo gemen and stir-fried ginkgo. Conclusion Compared with the Chinese Pharmacopoeia 2015 edition, the first supplement, the character identification for ginkgo semen decoction pieces was added and the quality standards were improved. The moisture content of ginkgo semen decoction pieces needs to be strictly controlled under 10.0% to prevent mildew and insects.
