Research progress in the relationship between loss of heterozygosity events and antifungal drug resistance in Candida albicans / 中华微生物学和免疫学杂志

Candida albicans as a pathogen of great clinical significance can widely colonize in many ecological niches of human body, especially in the immunocompromised population. Currently, antifungal drugs that can be used in clinical treatment are very limited. However, the genome of Candida albicans has a high rate of mutation, which can help it quickly develop resistance to antifungal drugs. Therefore, drug resistance in Candida albicans remains a great threat to clinical practice. This article focused on the frequent loss of heterozygosity (LOH) events in Candida albicans, summarized the association between LOH and other genomic variants and discussed the relationship of the frequency of de novo mutations, heterozygous status of key drug resistance genes and reproductive pattern with antifungal drug resistance.

Changes of serum transient receptor potential channel 1 in peripheral blood of patients with vascular depression / 中华行为医学与脑科学杂志

Objective@#To understand the changes of serum transient receptor potential channel 1(TRPC1) in patients with vascular depression.@*Methods@#58 patients with vascular depression, 49 patients with major depressive disorder and 38 healthy controls were recruited.The TRPC1 of all subjects were detected by ELISA.Patients with vascular depression and patients with primary depression were scaled by HAMD-17.The level of TRPC1 was contrasted in different ages groups and in different nosogenesis (cerebral infarction, ischemic cerebrovascular disease, old cerebral hemorrhage, cerebral microbleeds, vascular risk factors, etc.) of vascular depression.The relationship between TRPC1 level and severity of depressive symptoms was further analyzed.@*Results@#(1)The level of TRPC1 of serum((643.76±118.43)pg/ml) was decreased in patients with vascular depression compared with that in healthy controls ((712.48± 98.75) pg/ml). The level of TRPC1 in patients with vascular depression over 60 years ((601.43±113.55)pg/ml)was lower than that in patients with major depressive disorder over 60 years ((626.32±125.46)pg/ml) and healthy controls over 60 years((721.84± 99.62)pg/ml) .(2) Among the various causes of vascular depression, the level of TRPC1 in patients with cerebral infarction, ischemic cerebrovascular disease and cerebral microbleeds was significantly lower (P<0.05). (3) The levels of TRPC1 in the patients with vascular depression (r=-0.962, P<0.05) and patients with major depressive disorder (r=-0.674, P<0.05) were negatively correlated with HAMD-17 score.@*Conclusion@#The level of TRPC1 is lower in patients with vascular depression, which is more obvious in patients with cerebral infarction, ischemic cerebrovascular disease, and cerebral microhaemorrhage.The lower the level of TRPC1, the more severe the depression.The neuroprotective effect of TRPC1 is reduced in patients with vascular depression.The TRPC1 can be used as a biomarker for vascular depression.

Objective: To tease relevant research on the ethical review of Traditional Chinese medicine in Chi-na and reveal hot topics and trends in the field.Methods: Taking the academic papers included in the domestic database on ethical review of Traditional Chinese medicine as literature samples,the BICOMB and SPSS22.0 soft-ware were used for document information mining,and the high-frequency keywords were analyzed used co-word clustering and thematic strategic diagram.Results: A total of 78 documents were retrieved,and 17 high-frequen-cy keywords were used.The four major hotspots in the field of ethical review of Traditional Chinese medicine in-cluded: institution building and system certification,GCP ethics optimization,ethical principle research,trial scheme design and project quality management.Conclusion: In recent years,the ethical review of Traditional Chi-nese medicine has been explored by scholars and institutions in China from multiple perspectives,and further re-search can be strengthened combined with the current weak areas,in order to increase the overall level of ethical review of Traditional Chinese Medicine.

Effect of hyperthermia-induced MMP-9 on expression of claudin-1 in in vitro blood brain barrier model / 中华老年心脑血管病杂志

Objective To study the effect of hyperthermia-induced MMP-9 on expression of claudin-1 in in vitro BBB model.Methods BMEC and astrocytes were cultured.An in vitro BBB model was established with its permeability assayed by LY test.The BBB model was randomly divided into 37℃ group,39℃ group,37℃+MMP-9 group and 39℃+MMP-9 group.The permeability of BBB model was recorded at 30,60 and 90 min respectively.Expression of claudin-1 in BMEC was detected by Western blot with immunocytochemical staining.Results The permeability of BBB model was higher in 39℃ group than in 37℃ group (P＜0.05) and was significantly higher in 39℃ +MMP-9 group than in 37℃ group (P＜0.05).The number of claudin-1 positive BMEC was smaller in 39℃ +MMP-9 group than in 37℃ group at the same time points (P＜0.05) and in 39℃ +MMP-9 group than in 39℃ group at 90 min (75.0±12.8/HP vs 97.0±6.1/HP,P＜0.05).The expression level of claudin-1 was lower in 39℃ group than in 37℃ group (P＜0.05) and was significantly higher in 39℃ +MMP-9 group than in 37℃ group (P＜0.05),which further increased with the increasing time.Conclusion Hyperthermia can downregulate the expression of claudin-1 in in vitro BBB model and upregulate the permeability of in vitro BBB model.Adding MMP-9 can further aggrevate the damage of in vitro BBB model,indicating that hyperthermia can aggrevate the damage of in vitro BBB model through MMP-9.

Cost Effectiveness Analysis on Integrated Traditional Chinese and Western Medicine in ;Treatment of Leukemia / 中国中医药信息杂志

Objective To analyze the features of health economics in the treatment of leukemia;To evaluate the improvement trend of levels of clinical diagnosis, treatment and management. Methods TCM medical information dtatabase and electronic medical system in Zhejing Province TCM Hospital from January 2010 to December 2015 were retrived. According to inclusion and exclusion criteria, leukemia patients’ materials that met the critiria were screened. The total hospitalization fees, cost of Western medicine, the cost of Chinese patent medicine, cost of TCM decoction pieces, and cost of blood transfusion were set as costs, while white blood cell count, hemoglobin concentration, and platelet count were set as effectiveness indicators for cost effectiveness analysis. Results In patients with low white blood cell count increased unit white blood cell count, patients with high white blood cell count declined unit white blood cell count, patients with low hemoglobin increased unit hemoglobin count and patients with low platelet count increased unit platelet count, the total hospitalization fees, cost of Western medicine, the cost of Chinese patent medicine, cost of TCM decoction pieces, and blood transfusionfor the above increases showed a decreasing trend. Conclusion Health economics advantages in three blood routine indicators after treatment of integrated traditional Chinese and western medicine for leukemia is increasing year by year.

Matrix metalloproteinase-9 and ischemic stroke / 国际脑血管病杂志

The pathophysiological mechanism of ischemic stroke is very complex.Many intracellular and extracellular factors play the important roles in it.Studies have shown that the expression of matrix metalloproteinase-9 (MMP-9) has the changes of quantity,time and space after stroke.These changes are closely associated with the occurrence and development of ischemic stroke.The experimental studies focusing on MMP-9 also have made corresponding effects.The in-depth study of the mechanism of action of MMP-9 is expected to provide a new approach for the diagnosis and treatment of ischemic stroke.
