0.05).It was revealed that all the patients followed up 3 to 6 months after treatment were free from complaints of the involved teeth,with nomal food intake and mastication.No abnormal adjacent tissues of dental roots were detected by imaging examination.Conclusion For the vital teeth,the similar clinical effect may be obtained by one-visit RCT and multi-visit RCT.

Objective To investigate the changes and clinical significances of the chemokines of interferon-?-inducible protein-10(IP-10),monocyte chemoattractant protein-1(MCP-1) and growth-related oncogene-?(Gro-?) involved in pathagenesis of Kawasaki disease(KD) and HenochSchonlein purpura(HSP).Methods The chemokines production of IP-10,MCP-1 and Gro-? were assayed by ELISA in 15 patients with KD,12 patients with HSP and 10 healthy children.Results The plasma levels of IP-10 and MCP-1 were markedly elevated in KD group [(394.2?176.4)and(420.5?163.4)ng?L-1]compared with HSP group[(94.8?66.4)and(109.2?76.6)ng?L-1] and the control group [(76.4?46.5)and(87.7?47.8)ng?L-1](all P0.05),as well as Gro-? between the three groups.Conclusion Monocyte may enhance the immune damage in KD pathogenesis,and the levels of IP-10,MCP-1 may be important indexes for KD.Neutrophil may be not involved in pathogenesis of HSP and KD.

The teaching method of critical thinking was introduced in the course of medical physics for undergraduate students by means of case teaching,PBL teaching,Bio-Physics teaching and research-oriented teaching patterns.The teaching quality and both the abilities of critical thinking and innovation of the students were enhanced.

Cordyceps militaris is of significant economic value in medical care and food exploitation because of its many physiological activities. This paper reviews(1) the taxonomic position of its anamorph,(2) interesting culture ways,(3) strain degeneration and genetic variability,and(4) research progress in bioactive compounds and pharmacological functions.

The exploration of drug toxicity and mechanisms is a vital component in ensuring the safe use of drugs in clinical practice, as this topic has attracted widespread concern. The intestinal flora holds great significance for drug metabolism, efficacy and mechanism, and is an instrumental metabolic organ that facilitates material information transfer and biotransformation. However, an increasing number of studies have shown that intestinal bacteria are closely related to the toxicity of specific drugs. On the one hand, drugs are transformed into toxic metabolites under the influence of intestinal bacteria, thus inducing direct drug toxicity. On the other hand, the composition and function of the intestinal flora are altered under drug influence, resulting in disruption of endogenous metabolic pathways. Consequently, this disruption compromises the intestinal barrier and affects other organs, leading to indirect drug toxicity. This review meticulously compiles recent examples of drug toxicity attributed to intestinal bacteria, explores in depth the contention that metabolic enzymes of gut microbiota may be of great influence on oral drug toxicity, and outlines prospective avenues for future research on gut microbiota and drug toxicity and mechanisms. This not only provides novel perspectives for the judicious clinical utilization of drugs but also offers insights for the safety assessment of innovative pharmaceuticals.

Background The pathological foundation of diabetic retinopathy is the breakdown of the bloodretina barrier induced by multifactors.Objective This study was to investigate the retinal morphologic change and the levels of serum vascular endothelial growth factor(VEGF),endothelin(ET)and nitric oxide(NO)in diabetic rats.Methods Forty healthy female SD rats were randomly divided into experimental group and control group and 20 rats for each group.Acute diabetes models were established by the intraperitoneal injection of 60 mg/kg streptozotocin in experimental group and the equal volume of buffer solution was injected at the same way in the control group.The serum VEGF level,ET level and NO concentration of diabetic and control rats were detected using ELISA double antibody sandwich method,125I radioimmune method and nitrate reduction method respectively at 2,4,6 and 8 weeks after injection.The eyeballs of rats were enucleated at the eighth week for retinal pathologic examination.This experiment followed the Measures for the administration of experimental animals of Shanghai City.Results The retinal structure was normal throughout the experimental duration in the control group.However,retinal edema and cellular disorganization appeared at 4 months and retinal blooding could be seen with the extending of diabetes course.The levels of serum VEGF and ET in each experimental group were significantly higher than those in control groups(P＜0.05).The levels of serum NO elevated in 2-month experimental group compared with same-phase control group(Z =-2.193,P＜0.05),and those in 6-and 8-month experimental groups were significantly lower than in corresponding control groups(Z =-2.449,Z =-2.236,P＜0.05).With the progression of the disease,the levels of VEGF and ET increased gradually,but the levels of NO decreased gradually,showing statistically significant differences(P＜0.05).The level of serum VEGF showed a positive correlation with serum ET level and a negative correlation with the serum NO concentration(r=-0.814,r=-0.803,P＜0.01)in the experimental group.A negative leaner relation was also found between serum ET level and serum NO concentration(r=0.821,P＜0.01).Conclusions The serum VEGF,ET and NO levels are closely associated with the degree of retinal lesion in early diabetic models.These results suggest that serum VEGF,ET and NO levels may be the important indexes predicting the course of retinal disease in diabetic rats.
