RESUMO

OBJECTIVE To compare the efficacy and safety of Cefazolin sodium for injection, Cefuroxime sodium for injection, and Ceftazidime for injection from nationally organized centralized drug procurement (hereinafter referred to as “centralized procurement”) and non-centralized procurement in patients with bacterial infection. METHODS The case data of hospitalized patients who had used 3 kinds of Cephalosporins for injection from centralized procurement or non-centralized procurement in the treatment of bacterial infections were retrospectively collected from 19 medical institutions in Kunming from January 2020 to September 2022. After balancing the baseline differences between the groups with the propensity score matching method, the effectiveness and safety differences of 3 kinds of Cephalosporins for injection from centralized procurement or non- centralized procurement were compared respectively. RESULTS After balancing the baseline differences among the groups, 394 cases in each group of Cefazolin sodium for injection from centralized procurement or non-centralized procurement, 472 cases in each group of Cefuroxime sodium for injection from centralized procurement or non-centralized procurement, 504 cases in group of Ceftazidime for injection from centralized procurement and 590 cases in group of non-centralized procurement were included in the analysis. In terms of effectiveness, there were no significant differences in clinical response rate, 72 h response rate, bacterial clearance rate, and the recovery rate of body temperature, white blood cell count, neutrophil count, neutrophil percentage, C-reactive protein, procalcitonin recovery between the centralized procurement group and non-centralized procurement group of Cefazolin sodium for injection and Cefuroxime sodium for injection (P>0.05). The proportion of patients in centralized procurement group of Ceftazidime for injection with C-reactive protein restored to normal reference range was significantly higher than that in non-centralized procurement group (46.9% vs. 27.9%, P<0.05), but there were no statistically significant differences in other effectiveness indicators among groups (P>0.05). In terms of safety, there was no statistical difference in the incidence of adverse drug reactions between centralized procurement group and non-centralized procurement group of 3 kinds of Cephalosporins for injection (P>0.05); the incidence of platelet count reduction in centralized procurement group of Cefazolin sodium for injection was significantly higher than non-centralized procurement group (20.7% vs. 7.1%, P<0.05), the incidence of eosinophilia elevation in centralized procurement group of Ceftazidime for injection was significantly higher than non-centralized procurement group (5.3% vs. 1.9%, P<0.05). In addition, there was no statistically significant difference in the abnormal rates of other laboratory indicators among the three types of injection Cephalosporins (P> 0.05). CONCLUSIONS The efficacy of 3 kinds of Cephalosporin for injection from centralized procurement is not inferior to non- centralized procurement varieties, and the safety is equivalent to that of non-centralized procurement varieties.

RESUMO

Rejection has constantly been an unresolved challenge in the field of organ transplantation. The research on the mechanism of rejection plays a significant role in improving the efficacy of organ transplantation and enhancing the survival rate of graft. The innate and specific immune responses of the human body jointly participate in the graft rejection, leading to graft injury. In recent years, multiple researchers have conducted in-depth studies on the mechanism underlying the role of microRNA (miR) in regulating rejection. Among them, miR-155 has been widely considered as a key factor involved in immune regulation. The expression level and functional status of miR-155 may be intimately associated with the occurrence of rejection, which may become a new target for overcoming rejection. In this article, relevant studies on the role of miR-155 in regulating key immune cells in innate and specific immune responses were reviewed, aiming to provide novel ideas for the development of new immunosuppressants and rejection therapy.

RESUMO

Tacrolimus (Tac) is a commonly used immunosuppressant after organ transplantation, which has high immunosuppressive efficacy. However, the pharmacokinetics of Tac significantly differ among individuals, and gene polymorphism is the main influencing factor. In recent years, the gene polymorphism of drug transporter has become a novel research hotspot. Nevertheless, the effect of the gene polymorphism of transporter on Tac pharmacokinetics remains controversial. Consequently, the correlation between the gene polymorphism of transporter and Tac blood concentration plays a significant role in guiding Tac-based individualized immunosuppressive therapy. In this article, the research progresses on the gene polymorphism of adenosine triphosphate-binding cassette (ABC) transporter and solute carrier (SLC) transporter in organ transplantation was reviewed. The correlation between the gene polymorphism of transporter and Tac blood concentration was summarized, aiming to provide reference for Tac-based individualized therapy.

RESUMO

The outbreak of COVID-19 has infected millions of people and caused hundreds of thousands of deaths worldwide. As there is no specific medicines or effective vaccines against 2019-nCoV at present, it is an alternative strategy to repurpose existing drugs for new diseases. Cyclosporin A inhibits the replication of coronaviruses by binding to cellular cyclophilins. Chloroquine/hydroxychloroquine can block virus-receptor binding through interfering with terminal glycosylation of the cellular receptor angiotensin-converting enzyme 2 (ACE2). Trastuzumab prevents the binding of IL-6 to both sIL-6R and mIL-6R and thereby inhibits the cytokine storm syndrome induced by COVID-19. This paper discussed the potential anti-2019-nCoV effects of some common immunosuppressant including cyclosporine, chloroquine/hydroxychloroquine, and tocilizumab.

RESUMO

Background and purpose:Thalidomide can enhance the radiation sensitivity on tumor effectively, but the mechanism of radiosensitization is still unclear. The present study aimed to investigate whether thalidomide could enhance the radiation sensitivity on colon cancer transplanted tumor of mouse, and to investigate the underlying mechanism. Methods: We established the model of colon26 colonic carcinoma, and the mice were divided into 4 groups:Control group, the thalidomide group, the radiotherapy group and thalidomide+radiotherapy group. From the day of treatment, tumors were measured every other day. Then, the xenograft tumor growth curve was depicted. Tumor volumes were measured in different treatment groups, then, the inhibitory rates of tumor growth were calcutated. Using immunohistochemical method in to detect the expression of microvessel density (MVD) in tumor tissue. Results:The mean tumor volumes at day 22 were (4.97±1.20)cm3 (control group), (2.90±0.92)cm3 (T group), (2.66±0.88)cm3 (R group), and (1.89±0.76)cm3 (T+R group). The tumor inhibition rate in the combination group (61.9%) was signiifcantly higher than the other groups (41.7%, 46.5%, P<0.05). The radiotherapy sensitization enhancement ratio of the combined treatment group was 2.27 times than in the radiotherapy group. Thalidomide combined with radiation therapy can significantly inhibit microvessel density of tumor:The decreasing MVD of T+R group, T group and R group were respectively 46.8%, 40.7%and 37.7%, and there was statistical significance between T+R group and T group (P<0.05 ), so as between T+R group and R group. It could be found more necrotic cells in tumor of group, and there was statistical signiifcance between T+R group and control group (P<0.05). Conclusion:Thalidomide can enhance the radiosensitivity mice of colonic carcinoma, and its mechanism may be related to the inhibition of tumor angiogenesis related.
