Hyperuricemia is the second largest metabolic disease next to the diabetes and is an independent risk factor for other chronic diseases. With the increase of incidence rate, it has become one of the common chronic diseases in general practice. For the implementation of hierarchical medical system, it is necessary to establish a sound and effective community model for the management of hyperuricemia in China. This article reviews the literature at home and abroad to provide information for building a community management model of hyperuricemic patients.

ObjectiveTo observe the effects of enriched environment on depressive-like behaviors induced by chronic stress in rats.MethodsAdult rats were randomly divided into stress group and the control group,then after 21 days of stress,rats were raised in an enrich environment (EE) or standard environment (SE)for 28 days.Open field test,forced swimming test and sucrose preference test were used to detect depressive-like behavior in rats.Results ( 1 ) Open field test showed that grid crossing,standing and rearing in stress ( no gap)rats were significantly reduced ( 13.88 ±4.38 vs 45.00 ± 10.19,9.13 ±2.54 vs 16.38 ±4.11 and 4.78 ± 1.39vs 10.51 ± 2.52 ; n =8 ; P< 0.01 respectively) ; but grid crossing and standing in stress + EE rats were significantly increased than stress + SE rats (41.61 ± 10.53 vs 26.25 ± 6.18 and 16.79 ± 3.49 vs 11.25 ± 3.12 ; n =8 ; P<0.01 and P<0.05 respectively).(2) Sucrose preference tests showed that sucrose consumption and sucrose preference% in stress ( no gap) rats were significantly decreased than those in the control group ( 5.22 ± 0.94 vs 10.61 ±2.59 and (49.11 ±6.77)% vs(63.38 ±8.36)% ; n=8; P<0.01 respectively).(3) Forced swimming test showed that immobility time was increased in stress ( no gap) rats ( ( 19.5 ± 5.43 ) s vs ( 12.75 ± 3.9 ) s; n =8 ; P < 0.05 ) and was restored by EE compared to SE rats ( ( 10.25 ± 3.57) s vs ( 17.75 ± 5.45 ) s; n =8 ; P < 0.05).ConclusionChronic stress can reduce depressive-like behaviors,and EE can restore depressive-like behaviors induced by chronic stress.

Objective To explore the role of humall papillomavims (HPV) type 16 E6 variants in the persistent infection and recurrence of the cervical high-grade squamous intraepithelial lesion (HSIL) after conization. Motheds During May to June 2012, 100 HSIL patients with HPV16 positive but negative at the margin after Loop electrosurgical excision procedure (LEEP) were selected from Shanghai People′s Hospital of Pudong District. The gene sequencing was done to the E6. The patients were followed up for 2 years. The E6 gene sequencing was done again to detect the HPV16 variants among those with persistent infections and recurrence. Results Among the 100 cases, E6 variants were detected, 81% of them HPV E6 variants Asian prototype, 14% European variant; 2% European prototype (EP) and 3% African variant 1. LEEP for Asian prototype was susceptible to the clearance of HPV16 (P < 0.001). The European variants of T350G, and A442C were correlated with persistent infection and recurrence (P < 0.001). Conclusion The HPV16 variant is closely related to the HSIL incidence. HSIL caused by HPV16 in Pudong New Area of Shanghai belong to the Asian type variant. The European variants of E6 , T350G/A442C were likely related to the recurrence of HPV16.

Objective · To explore the change of metabolomic profiling after erlotinib (anepithelial growth factor receptor tyrosine kinase inhibitor)resistance of lung adenocarcinoma cells (PC9-ER), and find the differential metabolome associated witherlotinib resistance. Methods · Metabolic profiling of PC9-ER cells and homologous parent PC9 cells was acquired by the ultraperformance liquid chromatography tandem quadrupole time-of-flight mass spectrometry (UPLC-QTOF/MS). The data were analyzed by multi-dimensional statistical methods, such as partial least squares projection to latent structures-discriminant analysis (PLS-DA), to select and identify differential metabolites associated with erlotinib resistance. Results · A total of 14 differential metabolites were identified in PC9-ER cells. Seven up-regulated metabolites included N-acetylspermidine, phosphatidylethanolamine, AMP, pantothenic acid,proline, glutamate, and histidine, while seven down-regulated metabolites included citrulline, phosphorylcholine, glutathione, cysteinylglycine, glutathione oxidized, NAD, and S-adenosylmethionine, mainly participating in glutathione metabolism, glutamate metabolism, ammonia recycling, and protein biosynthesis. Conclusion · Metabolic profiling of erlotinib-resistant lung adenocarcinoma cells was changed. The information of differential metabolites associated with erlotinib resistance could provide clues for new resistance mechanisms and potential metabolism-related drug targets.

Apolipoprotein C3 (APOC3) is a multifunctional protein.Its concentration is positively correlated with triglyceride (TG) levels and is an independent risk factor for coronary heart disease (CAD) prediction and development.Recent studies showed that APOC3 could not only regulate triglyceride-rich lipoproteins (TRL) metabolism,but also regulated endothelial function,that is,it could induce endothelial dysfunction and disorders of lipid metabolism.Gradually,APOC3 induces atherosclerosis (AS),increases the risk of the occurrence of CAD and other related diseases.APOC3 polymorphisms are also closely related to related diseases.
