1.The progress of study on hyperuricemia
Chinese Pharmacological Bulletin 2003;0(10):-
Uric acid is an end product of purine degradation in humans and normally depends upon renal excretion for the majority. Hyperuricemia is likely to cause gout, renal disease, or stones, and associated with cardiovascular impairment over the long term. The prevalence of gout and hyperuricemia appears to be on the increase in recent years. The present paper reviews the relationships between hyperuricemia and insulin resistance,purine metabolism and uric acid elimination , the genetics study and the mechanisms of hyperuricemia.
2.Research progress for animal hyperuricemia model
Chinese Pharmacological Bulletin 1986;0(04):-
Hyperuricemia is induced by the mechanism of the elevated production of uric acid or the decreased renal excretion of uric acid. At present, there are three major methods to establish models for hyperuricemia: first, it will elicit pronounced hyperuricemia when feeding or injecting the animal with hypoxanthine 600~1000 mg?kg -1 , xanthine 600 mg?kg -1 , adenine 150~300 mg?kg -1 , yeast 15~30 g?kg -1 , uric acid 250 mg?kg -1 or 350~700 mg?kg -1 because of the elevated serum uric acid. Such effect will be also observed as administrating the animal with the inhibitors of uric acid excretion such as ethambutol 250 mg?kg -1 , nicotinic acid 100 mg?kg -1 at the same time of the above steps. Second, being an uricase inhibitor, when fed the rats 0 4 g?d -1 and uric acid 0 6 g?d -1 for 3~4 weeks, oxonic acid is able to cause the continuously elevated serum uric acid. Similarly, when potassium oxonate 300 mg?kg -1 ip only once, the serum uric acid in mice will be also elevated. Third, to destruct the urate oxidase gene (EC 1.7.3.3) in the mouse by homologous recombination in embryonic stem cells, and then the oxidase deficient mutant mouse as the hyperuricemia model, is generated by gene recombination.The rats and the mice have urate oxidase, which can decompose the uric acid to allantoin, while the avian (such as chicken, coturnix and so on) have not.

Objective To investigate the effect of continuous nursing on the psychological status and quality of life in patients with low rectal cancer after Miles operation.Methods A total of 84 patients with low rectal carcinoma underwent Miles operation were selected from August 2014 to August 2016 in Henan Rongjun Hospital.The patients were divided into observation group (n =38) and control group (n =46) according to nursing measures.The patients in the control group were given routine nursing measures,while the patients in the observation group were given continuous nursing measures on the basis of routine nursing care.The psychological status and quality of life of the patients were compared between the two groups before and after intervention.Results There was no significant difference in swlf-rating anxiety scale (SAS) and self-rating depression scale(SDS) scores between the two groups before intervention (P > 0.05).After six months intervention,the SAS and SDS scores in the two groups were significantly lower than those before intervention,and the scores of SAS and SDS in the observation group were significantly lower than those in the control group (P <0.05).There was no significant difference in the quality of life between the two groups before intervention (P > 0.05).After six months intervention,the quality of life of patients in the two groups were significantly higher than those before intervention,and the quality of life of patients in the observation group were significantly higher than those in the control group (P < 0.05).Conclusion Continuous nursing can significantly improve the negative emotions of anxiety and depression,and improve the quality of life in patients with low rectal cancer after Miles operation.

Increasing evidence has proved that inflammation plays an extremely important role in tumorigenesis.As the most representative biomarker for inflammation,C-reactive protein (CRP) has been considered to be critically associated with the prognosis of a variety of malignant tumors,like renal cancer.Numerous studies have shown that CRP is a significant prognostic factor for renal cancer patients treated with surgery,cytokine therapy or molecular-targeted therapy,and CRP has been incorporated into some prognostic algorithms for renal cancer.

Glucocorticoid receptor (GR),a member of the steroid receptor superfamily,can mediate the signal pathway of ligands like glucocorticoids,regulate the transcription of target genes,and exert biological activity.GR is expressed in different degrees in three major kinds of urological malignant tumors including renal cancer,bladder cancer and prostate cancer.It also affects the metabolism of tumor cells,and is closely related to the occurrence,development and prognosis of tumors.GR provides an important clue for targeted therapy and endocrine therapy of urological malignant tumors.

Objective To prepare targeted micorbubble with low immunogenicity. Methods The microbubbles were produced with different phospholipids and identified by the fluorescent method. Detect the level of C3a after reaction with human serum in vitro with enzyme-linked immunosorboent assay (ELISA) method and the number of microbubble binding with the streptavidin packed on the dish by using the parallel plate flow chamber. Results The level of C3a was (1.037±0.047)ng/ml in MBb group,(1. 326 ± 0. 042)ng/ml in MBe group and ( 1.004 ± 0.031 ) ng/ml in MBc group. The level of C3a in MBb group was significantly lower than that in MBe group( P <0.05),and there was no significantly difference between MBb group and MBc group ( P > 0. 05). The parallel plate flow experiments showed that the number of MBb(15.2 ± 11.3) in each field of view binding with the streptavidin packed on the dish was significantly fewer than that of MBe ( 103.2 ± 28.3) ( P<0.05 ), and there was no significantly difference between MBb and MBc(17.8 ± 11.9) ( P >0.05). Conclusions The targeted microbubble with low immunogenicity has been prepared successfully,which can be used for further experiment in vivo.

Objective To establish a real-time quantitative polymerase chain reaction (RQ-PCR) assay for fast detection of Aspergillus fumigatus genome in human whole blood samples and explore its clinical application.Methods The primers and the TaqMan-probe were designed on the basis of the multi-copy ITS1-5. 8S region of the rDNA of Aspergillus fumigatus. The Aspergillus fumigatus genomic DNA were extracted with QIAamp(R) DNA Blood Mini Kit.A 20 μl RQ-PCR amplification system was established, and the simulated blood samples containing various given load of Aspergillus fumigatus genome and the 66 whole blood samples of the surgical febrile patients were examined. Results The detection limit of the RQ-PCR instrument is 10-1 genomes/μl DNA sample,namely 78 CFU/ml whole blood. The specificity and the sensitivity were 94. 25% and 99. 04% respectively; and the positive predictive value and negative predictive value were 97. 63% and 97. 62% respectively. The average relative error of the quantitative results was (3. 67 ±13. 19)%, and the intra- and the inter-assay average coefficients of variation were (12.38 ± 1. 53)% and (16. 27 ±2. 72)% , respectively. The average recovery rate of Aspergillus fumigatus genomic DNA in human whole blood samples was (107. 81 ±25. 92)% , and the average coefficient of variation of the average recovery rate was (26. 24 ± 5.62) % . No Aspergillus fumigatus genomic DNA was detected among the 66 blood samples of the surgical febrile patients. Conclusions The RQ-PCR assay for fast quantitative detection of Aspergillus fumigatus genome in human whole blood samples is of high sensitivity, specificity,accuracy and precision. The Aspergillus fumigatus genome was not detected in this group of surgical febrile patients.
