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.

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 explore the pharmaceutical care for the elderly cancer patients complicated with bone marrow suppres-sion by clinical pharmacists. Methods:Clinical pharmacists performed the pharmaceutical care through the evaluation of chemothera-py, symptomatic treatment for bone marrow suppression and infection prevention after bone marrow suppression etc. Results:The bone marrow suppression was alleviated without bleeding related with the decrease of platelet and infection. Conclusion:The pharmaceutical care performed by clinical pharmacist can enhance the safety and effectiveness of medication.

AIM To establish mice hyperuricemia model METHOD Yeast extract paste 7 5～30 g?kg -1 was given to mice by ig once daily for 7,14,21,28 consecutive days, and detected the level of uric acid in serum RESULT The serum uric acid level in mice were (271 8?53 2),(215 4?31 5),(195 9?56 0),(142 1?30 7) ?mol?L -1 in 30 g?kg -1 group after administration 1,2,3,4 weeks;and (226 8?40 7),(148 67?30 4),(176 9?27 0),(119 3?27 4) ?mol?L -1 in 15 g?kg -1 group after administration 1,2,3,4 weeks;In 7 5 g?kg -1 group the serum uric acid level was (117 0?29 0) ?mol?L -1 after 1 week, respectively CONCLUSION Yeast extract paste (15～30) g?kg -1 given by ig could form mice hyperuricemia model, and the hyperuricemia could last 1～2 weeks

Aim To investigate the rationality and the dose of TSD combined with TSA on reducing serum uric acid and anti-inflammatory.Methods Mice hyperuricemic models were made by uric acid intraperitoneal injection or yeast extract paste intragastric administration.Mice ear swelling model was induced by locally painting dimethylbenzene.Optimized combination dosage of TSD and TSA was obtained using the Codrug software.Results In the mice hyperuricemic models,the serum uric acid in TSD group,TSD plus TSA group and positive control groups was significantly reduced compared with the model group(P

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 evaluate the therapeutic efficacy and safety of radiofrequency ablation (RFA) combined with ethanol injection with a multipronged needle under ultrasound guidance for the treatment of hepatocellular carcinoma (HCC) larger than 3 cm in diameter.Methods 65 patients with 67HCC nodules ranging from 3.1 to 7.0 cm in diameter were treated percutaneously under ultrasound guidance.Tumor response and complications after treatment were observed.Results Complete ablation was achieved in 94.0％ (63/67) of HCC nodules.4 residual tumor nodules received complete ablation after additional treatment.Ablation-related major complications was occurred in 3 patients,including liver abscess in 1 case,abdominal bleeding in 1 case and massive ascites in 1 case,all were cured by conservative therapy.After a mean follow-up period of (20.0 ± 7.6) months (6.7-32.6 months),local-tumor progression was observed in 10 (14.9％) of 67 HCC nodules,and distant recurrence was observed in 32 (49.2％) of 65patients.The 1-year and 2-year survival rate were 93.1 ％ and 88.1％,respectively.Conclusions RFA combined with ethanol injetion with a multipronged needle is a safe and effective technique for the treatment of hepatocellular carcinoma larger than 3 cm,especially 3-5 cm in diameter.
