Selenoproteins, as the active form of selenium, play an important role in various physiological and pathological processes, such as anti-oxidation, anti-tumor, immune response, metabolic regulation, reproduction and aging. Although the expression level of selenoproteins in adipose tissue is significantly influenced by dietary selenium intake, it is closely related to the homeostasis of adipose tissue. In this review, we summarized the role of selenoproteins in the physiological function of adipose tissue and the pathogenesis of obesity in recent years, in order to provide a rationale for developing potential therapeutic agents for the treatment of obesity and related metabolic diseases.

As a recognized rare and highly fatal disease, hereditary angioedema (HAE) is difficult to diagnose and characterized by recurrent edema involving the head, limbs, genitals and larynx, etc. Diagnosis of HAE is not difficult. However, low incidence and lack of clinical characteristics lead to difficulty of doctors on timely diagnosis and correct intervention for HAE patients. Therefore, it is crucial to improve the awareness of this disease and prevent its recurrence. for HAE patients. In view of absent cognition of doctors and the general public on HAE, patients often suffer from sudden death or become disabled due to laryngeal edema which cannot be treated in time. Thus, based on the Internet mobile terminal platform, the team set up an all-day rapid emergency response system which is provided for HAE patients by setting up "one-click help". The aim is to offer optimization on overall management of HAE and designed the intelligent follow-up management to provide timely assistance and specialized suggestion for patients with acute attacks.

Allergic diseases affect about 40% of the world's population. Environmental factors are important in the occurrence and development of allergic diseases. Dust mites are one of the most important allergens in the indoor environment. The World Health Organization proposes the "four-in-one, combination of prevention and treatment" treatment principle for allergic diseases, in which environmental control to avoid or reduce allergens is the first choice for treatment. Modern people spend much more time at home (including sleeping) than outdoors, and the control of the home environment is particularly critical. This practice introduces the hypoallergenic home visit program, which including home environment assessment, environmental and behavioral intervention guidance, and common household hypoallergenic supplies and service guidance for the patient's home environment. The real-time semi-quantitative testing of dust mite allergens, qualitative assessments of other indoor allergens, record of patients' household items and lifestyle, and precise, individualized patient prevention and control education will be conducted. The hypoallergenic home visit program improves the doctors' diagnosis and treatment data dimension, and becomes a patient management tool for doctors outside the hospital. It also helps patients continue to scientifically avoid allergens and irritants in the environment, effectively build a hypoallergenic home environment, reduce exposure to allergens in the home environment, and achieve the goal of combining the prevention and treatment of allergic diseases.

BACKGROUND: Albuvirtide is a once-weekly injectable human immunodeficiency virus (HIV)-1 fusion inhibitor. We present interim data for a phase 3 trial assessing the safety and efficacy of albuvirtide plus lopinavir-ritonavir in HIV-1-infected adults already treated with antiretroviral drugs. METHODS: We carried out a 48-week, randomized, controlled, open-label non-inferiority trial at 12 sites in China. Adults on the World Health Organization (WHO)-recommended first-line treatment for >6 months with a plasma viral load >1000 copies/mL were enrolled and randomly assigned (1:1) to receive albuvirtide (once weekly) plus ritonavir-boosted lopinavir (ABT group) or the WHO-recommended second-line treatment (NRTI group). The primary endpoint was the proportion of patients with a plasma viral load below 50 copies/mL at 48 weeks. Non-inferiority was prespecified with a margin of 12%. RESULTS: At the time of analysis, week 24 data were available for 83 and 92 patients, and week 48 data were available for 46 and 50 patients in the albuvirtide and NRTI groups, respectively. At 48 weeks, 80.4% of patients in the ABT group and 66.0% of those in the NRTI group had HIV-1 RNA levels below 50 copies/mL, meeting the criteria for non-inferiority. For the per-protocol population, the superiority of albuvirtide over NRTI was demonstrated. The frequency of grade 3 to 4 adverse events was similar in the two groups; the most common adverse events were diarrhea, upper respiratory tract infections, and grade 3 to 4 increases in triglyceride concentration. Renal function was significantly more impaired at 12 weeks in the patients of the NRTI group who received tenofovir disoproxil fumarate than in those of the ABT group. CONCLUSIONS: The TALENT study is the first phase 3 trial of an injectable long-acting HIV drug. This interim analysis indicates that once-weekly albuvirtide in combination with ritonavir-boosted lopinavir is well tolerated and non-inferior to the WHO-recommended second-line regimen in patients with first-line treatment failure.

The solubility of nebivolol hydrochloride was determined in acidic aqueous media in the absence and presence of different concentration of NaCl, NaBr, or NaI at 37 ℃ in order to facilitate proper selection of dissolution media that have adequate discriminating power for enhancing the likelihood of a generic drug product to successfully pass in-vivo bioequivalence test. In the range of pH 5.0 to pH 1.0, the solubility of nebivolol hydrochloride decreased with the decrease in the pH of aqueous solution, and the solubility of nebivolol hydrochloride further decreased with the increase in the concentration of added sodium chloride. The solubility decrease of a few weakly basic drug molecules in acidic media and in higher concentration of added chloride was published previously by other researchers, and the observed decrease in the solubility in the presence of higher chloride concentration was interpreted in terms of common-ion effect. However, the results in this paper showed that the solubility of nebivolol hydrochloride also decreased when sodium chloride was replaced with sodium bromide or iodide. The approach described in this paper (i.e. substituting sodium chloride with sodium bromide or iodide) provides an effective method to verify whether common-ion effect is the true (or at least the sole) driving force behind the observed decrease in the solubility of nebivolol hydrochloride in the presence of sodium chloride. The solubility decrease reported in this paper can be interpreted in terms of salting-out effect of sodium chloride, bromide, and iodide. For hydrochloride salt of a weakly basic drug molecule like nebivolol hydrochloride, its solubility in an acidic dissolution medium can be purposely decreased to the lower end of sink condition by adding sodium chloride to make the resulting medium more discriminating. As shown in this paper, a medium at pH 1.2 with added sodium chloride is discriminating and this medium is shown to be bio-relevant to the in-vivo data collected under fasting condition (in-vivo study protocol was approved by Institutional Review Board).

Objective To investigate the effect of I1imidazoline receptor(I1R)on the expression and function of α2Aadrener-gic receptor(α2AAR)at the cellular level.Methods After sequencing and enzymatic identification,the mouse I1R and α2AAR plas-mids were transfected into CHO cells,respectively.The radioligand receptor binding assay and flow cytometry were used to select sin-gle cell clones,and the CHO cell lines stably expressing the mouse I1R or α2AAR were established.The CHO cell line that stably ex-presses both the mouse I1R and α2AAR were also established by the same technology and strategy.Then,the radioligand receptor bind-ing assay was used to determine the affinity and expression of α2AAR. Further,the effects of I1R on the α2AAR expression and the α2AAR agonist dexmedetomidine(DEX)-induced extracellular regulated protein kinase(ERK)phosphorylation were evaluated by the Western blotting.Results After transfection of mouse I1R and α2AAR plasmids,CHO cells grew normally.In the saturation binding experiments of membrane proteins from the CHO cells that stably expressed α2AAR,the Kdand Bmaxvalues of 3H-RX821002 were(0.96 ± 0.24)nmol/L and(0.29 ± 0.03)nmol/g protein,respectively.The expression levels of I1R were significantly increased in both the CHO cells expressing I1R and the CHO cells co-expressing α2AAR and I1R(P<0.05,P<0.01),when the cells that express exogenous I1R or α2AAR alone were trasfected again with the I1R plasmids.Moreover,in the CHO cells that transfected both I1R and α2AAR sta-bly,the I1R expression upregulated the α2AAR expression(P<0.01),and further increased the ERK phosphorylation induced by DEX through activating α2AAR(P<0.01).Conclusion I1R could upregulate the α2AAR expression and the ERK phosphorylation in-duced by DEX through activating α2AAR in the CHO cells that express exogenous I1R and α2AAR.This study presents a groundwork for further exploration of the relationship between I1R and α2AAR at the molecular level in future.
