Résumé
Objective@#To establish the information solution for the classification and assessment of specimen quality based on the assembly line. @*Methods@#Before the samples entered into the assembly line, they were took pictures and screened by the image results. For the suspected samples, serum index was detected. Then, the classification criteria of specimen quality were set, and the alarm thresholds of serum indices for each item suitable for our laboratory were established. The results of serum indices were compiled into the corresponding text descriptions and automatically written into the notes of the result reports. The pictures of blood collection tubes were stored in the laboratory information management system (LIMS) and could be accessed at any time for verification. The samples intercepted by the automatic review were further reviewed by manual. @*Results@#The intra-assay coefficients of variation (CV) of serum indices for haemolysis (H), lipaemia (L) and icterus (I) were 0.6%, 0.7% and 1.3%, respectively, indicating that the precision was good. Among 657 770 samples detected by the assembly line, 11.9% of samples were screened out before they entered the assembly line. The detection of serum indices of these samples demonstrated that the samples with haemolysis, lipaemia and icterus accounted for 1.6%, 1.2% and 0.3% of the total samples, respectively. According to the results of the interference experiment, the alarm threshold of hemolytic serum index was set in 11 items, and those of lipaemia and icterus were set in 1 item. @*Conclusion@#By establishing the information solution of specimen quality based on the assembly line, the real-time classification prompting of specimen quality is realized, and the missed detection is avoided, which is helpful to reduce the pre-analysis errors caused by serum quality and simplify the laboratory workflow.

Objective To evaluate the elastic score (ES) and strain ratio (SR) in papillary thyroid carcinoma patients, and analyse their relationship with serologic index. Methods Totally one hundred and six patients with thyroid neoplasm were divided into papillary thyroid carcinoma group (n=56) and thyroid adenoma group ( n=50) according to histopathology results. Another fifty cases of healthy people were chosen as normal control group at the same period. The ES and SR were evacuated by color Doppler ultrasonic diagnostic apparatus in three groups of patients. Thyroid stimulating hormone (TSH), thyroglobulin antibody (TgAb), and thyroid peroxidase antibody (TpoAb) were detected by electrochemiluminescence immunoassay. Data of galectin-3 (Gal-3), vascular endothelial growth factor (VEGF), and cytokeratin 19 fragment (Cyfra21.1) were tested by automatic optical inspection. Results Indexes of ES, SR, Gal-3, VEGF and Cyfra21.1 showed statistically increasing tendency in the control group, thyroid adenoma group and papillary thyroid carcinoma group sequentially (P<0.05). Serum levels of TSH, TgAb and TpoAb were significantly higher in the papillary thyroid carcinoma group than those in the other two groups (P<0.05). And there were no significant differences in serum TSH, TgAb and TpoAb between the control group and thyroid adenoma group (P>0.05). There were positive correlation between ES, SR and TSH, TgAb, TpoAb, Gal-3, VEGF, Cyfra21.1 in patients with papillary thyroid carcinoma (P<0.05). Conclusion Papillary thyroid carcinoma shows increased ES and SR detected by ultrasound, and which are relevant to related serological indicators. The two indices may be used for auxiliary diagnosis of papillary thyroid carcinoma.

Objective To research the effect of letrozole combined with clomiphene on women with polycystic ovary induced infertility and the effect on matrix metalloproteinases-9(MMP-9),vascular endothelial growth factor(VEGF)and hepatocyte growth factor(HGF)levels.Methods 108 patients with polycystic ovary syndrome combined with infertility from February 2013 to August 2015 in our hospitolwere divided into control group and experimental group by lottery,54 cases in each groups,control group treated with clomiphene,the experimental group based on control group treatment with letrozole,the linical curative effect,MMP-9,VEGF and HGF level,sex hormones,insulin resistance index,adverse drug reactions of two groups were compared.Results The number of ovulation,advantage of ovulation number,normal rate of menstruation,ovulation rate and pregnancy ratesofin experimental group was higherthan the control group,the difference was statistically significant(P<0.05).The MMP-9,VEGF and HGF levels of experimental group was lower than the control group,the difference was statistically significant(P<0.05).The sex hormone level of experimental group was better than that of control group(P<0.05).The adverse reactions was no differences between the two groups.Conclusion The efficacy of letrozole combined with clomiphene in treatment of polycystic induced infertility,can inhibits MMP-9,VEGF and HGF expression,and with high safety.

Objective To investigate thecurative effect of Hanchuan Zupa granule combined with ventolin atomizing inhalation in the treatment of infantile bronchial asthma and the influence of serum myeloperoxidase(MPO),neutrophil(PMN),monocyte chemotactic protein-4(MCP-4).Methods 92 cases of infantile bronchial asthma from June 2015 to June 2016 in yiwu materal and child health care family planning senice center,according to the draw method was divided into the control group(n=46)and experimental group(n=46),the control group was treated with salbutamol inhalation,and the experimental group was based on control group treated with Hanchuan Zupa granule,the curative effect,MPO,PMN,MCP-4,inflammatory factor,the T lymphocyte subgroup,arterial blood gas index,clinical symptoms disappeared time and safety of two groups were observed.Results After treatmented,the total effective rate of experimental group was 93.48％higher than that of control group 76.08％,the difference was statistically significant(P<0.05).The MPO,PMN,MCP-4 of experimental group was lower than the control group,the difference was statistically significant(P<0.05).The inflammatory factor,T lymphocyte subgroup,arterial blood gas index in the experimental group were more significantly improved than those in the control group,the difference was statistically significant(P<0.05).The clinical symptoms disappear time of experimental group was better than that of control group,the difference was statistically significant(P<0.05).There was no significant difference in safety between the two groups.Conclusion Hanchuan Zupa granule combined withventolin atomizing inhalation of children with bronchial asthma in the exact effect,and down-regulated the expression of MPO,PMN,MCP-4,promote the recovery of children.
