OBJECTIVE:To provide reference for rational use of antiemetics in cancer patients. METHODS:Two thousand six hundred and sixteen pieces of medical orders of patients receiving antiemetics were collected from oncology department of our hospital via EMRS during Oct. 2015-Jun. 2016. RESULTS:Among 2 616 cases surveyed,1 301 cases conformed to inclusion and exclusion criteria,of which irrational use of drugs were found in 595 cases,760 times in total. Main manifestations were unsuitable drug selection(33.82%),irrational usage and dosage(25.26%),unsuitable drug combination(34.08%)and non-standard medication course(6.84%). The incidence of nausea in female was higher than male,with statistical sighificance(P=0.003),but gender had no significant effect on the incidence of nausea(P>0.05). Age had no significant effect on both nausea and vomiting(P>0.05). The control rate of nausea/vomiting in rational drug use group was higher than irrational drug use group. Average cost of antiemetic treatment of different emetic risk chemotherapy drugs in rational drug use group were all lower than irrational drug use group, indicating therapeutic efficacy could be guaranteed and economic burden was reduced in rational drug use group. CONCLUSIONS:The antiemetic plan should be selected rationally according to emetic risk degree of chemotherapy drugs. Patients receiving combined chemotherapy should select antiemetic plan according to highest emetic risk degree of chemotherapy drugs,and strictly master usage, dosage and duration. At the same time,treatment cost should be considered when selecting antiemetic plan to guarantee the safe, effective,economical and rational use of drugs.

To observe the histopathological changes of mice experimentally infected with plerocercoid,mice were infected orally by plerocercoids that were collected from Rana nigromaculatus (5 strips/mouse),and were killed 2-10 weeks later to undergo the histopathological observation.Plerocercoids were found in the skin,muscle,liver,lung cavity of mice.There were diffuse congested spots and capsule formation ;the fat tissue showed severe degeneration and necrosis.In the fibrous tissues ,moderate proliferation of the enveloping adipose tissue was demonstrated.In addition,a large number of acute and chronic inflammatory cell infiltration and abscess formation could be found.It is evident that the plerocercoids parasitize mainly in the subcutaneous tissues and muscles of mice.and mice experimentally infected with plerocercoids show different degree of histopathological changes.

OBJECTIVE:To investigate the characteristics and influential factors of adverse drug reactions(ADRs)of docetax-el in our hospital,and to provide suggestions for clinical rational drug use and individualized administration. METHODS:Medical records of patients receiving anti-tumor chemotherapy were extracted from hospital information system(HIS)of our hospital during Apr. 2014 and Oct. 2015,and Docetaxel related ADR reports were collected and comprehensively analyzed by retrospective classi-fied statistics. RESULTS:Among 417 cases,105 cases of docetaxel related ADR were reported. There were 69 patients aged 50-69 with highest ADR frequency. The ADR incidence of female patients was higher than that of male patients (29.29% vs. 19.66%). The incidence of docetaxel related ADR and arrest of bone marrow increased as the increase of drug dosage;the incidence of breast cancer ADR was the highest (46.03%),followed by lung cancer (37.25%) and gastric cancer (25.00%). The incidence of docetaxel+platinum chemotherapy plan ADR was the highest (35.10%). Main organs/system involved in ADR was hematological system (55.65%). CONCLUSIONS:The individual difference of docetaxal related ADR are great and affected by several factors. Individual physical condition of patients should be taken into consideration as early as possible,which can reduce the incidence of ADR and promote clinical rational drug use.

ObjectiveTo investigate the expression of ATA1 in the synovial tissue from patients with ankylosing spondylitis (AS) and to localize expression of ATA1 in AS synovial membranes.In addition,tag SNPs were genotyped to determine the possible association of this gene with AS risk.MethodsWestern blotting analysis was applied to determine the expression of ATA1 in the synovial tissues by comparing the expression profiles of AS(n=8),rheumatoid arthritis(RA,n=9) and osteoarthritis(OA,n=9) samples.Immuno-histochemistry was used to localize the expression of ATA1 in the synovial membrane.The levels of ATA1 in the synovial fluid of patients with AS were determined using ELISA with OA and RA as controls.Taqman method was used to genotype tag SNPs (rs2753934,rs2749531 and rs6575424) in 56 AS cases,260RA cases and 160 healthy controls.ANOVA,LSD test andx2 test were used for statistical analysis.Results Increased expression of ATA1 in synovial membranes of AS was found when compared with samples from RA and OA.ELISA results showed significantly elevated level of ATA1 in the synovial fluid of patients with AS (1.6+0.6),but not in samples of RA(1.4±0.5) and OA (1.2±0.5)(P＜0.05).Haplotype analysis did not reveal a haplotype association in AS or RA(P＞0.05).ConclusionThe current findings suggest that upregulation of ATA1 may play an important role in the pathogenesis of AS.

Objective:To determine whether CD46, CD55, and CD59 are differentially expressed in neoplastic and adjacent nor-mal colon tissues and to investigate their influence on clinicopathologic variables. Methods:Immunohistochemistry (a modified two-step method) was used to detect the expression of CD46, CD55, and CD59 in a tissue microarray of 121 cases of colon cancer and corre-sponding adjacent non-tumor tissues with detailed clinical information, including gender, age, differentiation, TNM classification, tu-mor location, and tumor histotype. The colon carcinoma microarray was constructed from patients' samples obtained from the Depart-ment of Gastrointestinal Surgery of Xijing Hospital of the Fourth Military Medical University between October 2004 and June 2006. The correlation between expression and clinicopathologic features was analyzed. Results:The expression levels of CD46, CD55, and CD59 were significantly higher in colon cancer tissues compared with those in normal adjacent colon tissues (P<0.001). CD46 expres-sion was not related to any specific patient characteristics, such as age, gender, grade of tumor differentiation, or TNM classification (P>0.05). The expression levels of CD55 and CD59 were correlated with the grade of colon cancer differentiation. Low levels of CD55 and CD59 were detected in cancer cells of highly differentiated cancer, whereas stronger staining for CD55 and CD59 was mainly observed in cancer cells of moderately and poorly differentiated colon cancer (P<0.05). In addition, the expression levels of CD55 and CD59 were higher in stages III and IV colon cancer than those in stages I and II according to TNM classification (P<0.05). Conclusion:CD46, CD55, and CD59 are up-regulated in colon cancer. Specifically, CD55 and CD59 are of clinical relevance to differentiation and TNM staging of colon cancer, and their expression might be closely related to clinical biological behaviors.
