A comprehensive regulation mechanism,as one of the five basic healthcare system components,plays an important role in safeguarding the health and life rights of all nationals of a country.The authors explored the construction of such a mechanism and related reform experiences of the healthcare industry in the context of building a healthy China.On such basis,the paper analyzed in depth the connotation of the comprehensive regulation and the existing challenges,in order to propose countermeasures for the establishment of a proactive,comprehensive and coordinated comprehensive regulation mechanism.

Objective To investigate the changes aad possible role of estrogen and its receptor ERα、ERβ、GPR30 in the pathogenesis of asymptomatic hyperuricemia.Methods The peripheral blood of 62 asymptomatic hyperuricemia patients (AH) and 68 healthy controls (HC) were collected.The expression of estradial (E2) in serum was detected by the chemilluminescent microparticle immunoassay (CMIA).The expression of ERα,ERβ,GPR30 mRNA in peripheral blood mononuclear cells (PBMCs) was measured using Real time quantitative polymerase chain reaction (RT-qPCR).Statistical Package form Soci-science (SPSS) 17.0 statistical software was used for data analysis.The measurement data were compared by t test,rank sum test or one factor analysis of variance test.The correlation between variables was used by Spearman correlation analysis.Results ① The expression of E2 in serum of the HC group was higher than that in the AH group [(38.7±10.2) pg/ml vs (33.7±8.6) pg/ml,Z=-0.356,P＜0.05].② The expression of ERα,GPR30 mRNA in PBMCs of HC group was increased,compared with that in the AH group (0.000 17±0.000 23 vs 0.000 12± 0.000 12,0.002 0±0.002 1 vs 0.001 5±0.000 8,Z=-2.112,-2.147,P＜0.05,respectively).No significant difference in PBMCs ERβ mRNA levels was found between HC group and AH group,while a slight but not significant increase was observed in HC group.③ The Spearman correlation analysis found that the expression of ERα and ERβ mRNA,E2 and GR,ERβ and GLU in the AH group were positively related (r=0.259,0.251,0.260,P＜0.05,respectively).Conclusion The expression of E2,ERα,ERβ,GPR30 mRNA in the peripheral blood of patients with AH is decreased,suggesting that the estrogen and its receptor may be involved in the patho-genesis of hyperuricemia.

Objective:To explore the changes of estrogen, androgen and progesterone in serum of male patients with primary gouty arthritis (pGA) and their possible role in the pathogenesis of gout.Methods:The serum, clinical data and laboratory parameters of 266 patients with PGA [including 93 patients with acute gout (AG), 118 patients with intermittent gout (IG), 55 patients with chronic gout (CG)] and 129 healthy controls (HC) were collected. The serum estradiol (E 2), progesterone (P), testosterone (T) and E 2/T were detected by CMIA Expression level. SPSS 17.0 statistical software was used for analysis, Wilcoxon rank sum test was used for comparison of measurement data between groups, and Spearman correlation analysis was used for correlation analysis between variables. Results:① The level of E 2 and T level in the serum of PGA, AG, IG and CG group was lower than that of the HC group [(30±8) pg/ml, (27±7) pg/ml, (31±8) pg/ml, (34±7) pg/ml, (35±10) pg/ml; F=17.770, P<0.05] and [(4.4±1.6) ng/ml, (3.8±1.4) ng/ml, (4.6±1.4) ng/ml, (5.1±2.0) ng/ml, (5.8±1.9) ng/ml; F=23.314, P<0.05], but there was no significant difference between HC group and CG group ( P>0.05), The serum E 2 and T levels in AG group were lower than those in IG and CG groups [(27±7) pg/ml, (31±8) pg/ml, (34±7) pg/ml; F=17.770, P<0.05] and [(3.8±1.4) ng/ml, (4.6±1.4) ng/ml, (5.1±2.0) ng/ml; F=23.314, P<0.05], andthe serum E 2 level in IG group was lower than that in CG group [(31±8) pg/ml, (34±7) pg/ml; F=17.770, P<0.05). The levels of P and E 2/T in HC group were lower than those in pGA and AG group [(0.24±0.10) ng/ml, (0.27±0.11)ng/ml, (0.30±0.15) ng/ml; F=5.124, P<0.05] and [(0.006 6±0.002 2) ng/ml, (0.007 6±0.003 2) ng/ml, (0.008 0±0.003 8) ng/ml; F=3.787, P<0.05), while those in IG and CG group were lower than those in AG group [(0.25±0.09) ng/ml, (0.26±0.08) ng/ml, (0.30±0.15) ng/ml; F=5.124, P<0.05]; ② Spearman correlation analysis showed that E 2 level in pGA group was positively correlated with T and CysC( r=0.310, P<0.01; r=0.164, P=0.008), negatively correlated with MO ( r=-0.133, P=0.030), P level was positively correlated with MO ( r=0.139, P=0.023), T level was positively correlated with Crea and CysC ( r=0.179, P=0.003; r=0.162, P=0.008), negatively correlated with WBC, GR and MO ( r=-0.140, P=0.022; r=-0.173, P=0.005; r=-0.149, P=0.015), E 2/T was positively correlated with apob1 and Glu ( r=0.131, P=0.032; r=0.140, P=0.023). In AG group, E 2 level was positively correlated with T and Crea ( r=0.234, P=0.024; r=0.245, P=0.018), T level was positively correlated with Crea ( r=0.349, P=0.001), and negatively correlated with apob1 ( r=-0.250, P=0.016), and E 2/T was positively correlated with apob1 ( r=0.276, P=0.007). In IG group, E 2 level was positively correlated with T ( r=0.269, P=0.003), and negatively correlated with MO ( r=-0.183, P=0.048), while P level was positively correlated with MO( r=0.204, P=0.027). Conclusion:The expression of E 2 and T in the peripheral blood serum of gout patients decreases significantly, the expression of P and E 2/T increases significantly, and there is a positive correlation between E 2 and T, as well as the inflammatory and glycolipid metabolism indexes of gout patients, suggesting that estrogen, androgen and progesterone may participate in the pathogenesis of gout by regulating the inflammation and metabolism of gout.

Objective:To analyze the prevalence of poor vision and spatial distribution characteristics among primary school students in Shenzhen.Methods:A cross-sectional study was conducted.Vision screening among primary school students in Shenzhen was carried out by myopia screening hospitals organized by Shenzhen Myopia Prevention and Control Center for Children and Adolescents using the logarithmic visual acuity chart in 2019.The prevalence of poor vision in different districts, different genders and different grades was calculated.Spatial distribution of the prevalence of poor vision was analyzed with Arcgis 10.2 software.This study adhered to the Declaration of Helsinki.Written informed consent was obtained from guardian of each subject.The study protocol was approved by an Ethics Committee of Shenzhen Eye Hospital (No.20201230-06).Results:A total of 1 044 545 students received the visual acuity examination.The prevalence of poor vision among primary school students in Shenzhen in 2019 was 53.4%(557 748/1 044 545). The prevalence of poor vision among primary school students in the former Shenzhen Special Economic Zone was 56.7%(172 771/304 532), which was higher than 52.0%(384 977/740 013) in areas outside the former Shenzhen Special Economic Zone, and the prevalence of poor vision among girls was 56.7%(268 201/473 164), which was higher than 50.7%(289 547/571 381) among boys, and the differences were statistically significant ( χ2=192.412, 375.434; both at P<0.001). As the grade increased, the prevalence of poor vision firstly decreased and then increased, showing an increasing tendency in general.The prevalence rate of poor vision among primary school students among grade 1 to 6 was 49.8%(99 615/200 203), 44.0%(86 521/196 800), 47.2%(82 848/175 331), 54.5%(89 737/164 731), 60.8%(96 271/158 298), and 68.9%(102 756/149 182), respectively, and a significant difference was found ( χ2=2 871.017, P<0.001). The global Moran I index in Shenzhen was 0.278.The local Moran I index and Geary coefficient in Guangming District were 0.933 and 0.78, respectively.The prevalence of poor vision in Guangming District and its surrounding areas was a low-low cluster. Conclusions:The prevalence of poor vision among primary school students in Shenzhen is spatially aggregated.
