Background Increase in ophthalmic optical medical instruments and microsurgical applications leads to retinal photochemical damage and other problems delivery of a variety of devices,so the in-depth study and understanding of its pathogenesis after retina light damage can provide a reference for the clinical treatment of related diseases.Objective This study was to investigate the therapeutic effect and relative mechanism of erythropoietin (EPO) on mouse retina photic injury by studying the expression of matrix metalloproteinases-2 (MMP-2)and MMP-9.Methods Fifty-two SPF BALB/c mice were randomized into normal control group,simple light-induced group and EPO pretreatment group by balloting method.The mice of simple light-induced group and EPO pretreatment group were continuously irradiated with 6000 lx diffuse light for 4 hours in a home-made box to establish the models of light-induced damage;while recombinant human EPO (rhEPO)of 5000 U/kg was intraperitoneally injected prior to the light exposure in the EPO pretreatment group.The expressions of MMP-2 and MMP-9 were examined at 6,12,36,72,96 hours and 7 days following light-exposure by immunohistochemistry.Results Edema and structural disorder of RPE cells appeared inthe simple light-induced group after light-exposure and aggravated with lapse of light-exposure time,but no similar change was seen until 7 days in the EPO pretreatment group.The immunohistochemistry findings showed that the expression of MMP-2(A value)in RPE cells was less in the normal mice.However,a large quantity of positive cells appeared in RPE layer 36 hours after light-exposure.Compared with the simple light-induced group,the positive expression of MMP-2 protein in EPO pretreatment group was significantly decreased,showing statistically significant differences among these three groups and different time points (Fgroup =3.68,P =0 04; Ftime =9.13,P=0.00).There was hardly any MMP-9 expression in the retina of the normal mice.In simple light-induced group,a few of positive cells appeared in RPE layer 6 hours after light-exposure and reached its peak 12 hours following light-exposure.The gradually down-regulation of MMP-9 expression happened 96 hours later following light-irradiation.The expression tendency of MMP-9 in EPO pretreatment group was similar to the simple light-induced group.Significant differences in expressions of MMP-9 were found among different groups and time points (Fgroup=3.61,P =0.04;Ftime =16.91,P=0.00).Conclusions MMP-2 and MMP-9 may be involved in the mechanism of retina photic injury by down-regulating the expression of MMP-2 and MMP-9 in RPE cells.

AIM To investigate actions of total paeony glycoside(TPG) on learning and memory capacity and related products of metabolism of senile mice induced by D galactose. METHODS The subacute senile mouse models induced by injection of D galactose subcutaneously were used. RESULTS TPG could improve the learning and memory capacity of model mice in shuttle test and enhance spatial resolution in water maze test. TPG not only reduced the content of monoamine oxidase(MAO) and inhibited the decrease of cholinesterase(CHE) significantly, but also lessened the level of malondialdehyde(MDA) and inhibited the decrease of superoxide dismutase(SOD) in cerebrum of model mice. TPG still promoted the recovery of lobar atrophy and hypoimmunity of senile mice remarkedly. CONCLUSION TPG possesses obvious effects of improvement on learning, spatial resolution and delaying senility.

Objective To investigate the iodine nutritional status in the key populations before and after the adjustment of salt iodine content in Yantai of Shandong.Methods In 2010 (the pre-adjustment period) and 2014,2015 (the post-adjustment period),the changes in the residents' iodized salt,the goiter prevalence and urinary iodine of children aged 8-10,the urinary iodine of pregnant women,and the iodine content of drinking water before and after the adjustment were analyzed.Results The coverage rate of iodized salt and the edible rate of qualified iodized salt were 98.27％ and 97.28％,respectively before the adjustment of salt iodine content,and 97.44％ and 96.14％ after the adjustment.The mean of salt iodine after the adjustment (21.96 mg/kg) was significantly lower than that of 2010 (31.45 mg/kg,t =66.29,P ＜ 0.05).The goiter prevalence of children aged 8-10 by thyroid palpation was 0.92％ in 2010,while it was 1.89％ by ultrasonic in 2014,2015.There was significant difference in the iodine nutritional status of children in 2010 (191.0 μg/L) and in 2014,2015 (173.0 μg/L,Z =3.56,P ＜ 0.05).The difference of iodine nutritional status in pregnant women between pre-adjustment (154.0 μg/L) and post-adjustment (130.4 μg/L) was also significant (Z =5.54,P ＜ 0.05).The median of water iodine was 5.4 μg/L after the adjustment.There were 52 towns with medians of water iodine below 10 μg/L.Conclusions The coverage rate of iodized salt and the edible rate of qualified iodized salt have all met the national standard before and after the adjustment of salt iodine content.The mean of salt iodine during 2014,2015 is significantly lower than that of 2010.Before and after the adjustment,the goiter rates of children aged 8-10 are all below 5％.The adjustment of salt iodine content is more suitable to children aged 8-10 than to pregnant women currently.It is suggested that pregnant women eat more foods rich in iodine.

OBJECTIVETo observe the short-term clinical effectiveness of bone ring graft technique and to summarize the key points of related surgical operation to provide comprehensive clinical guidelines.

METHODSFifteen patients with severe alveolar bone absorption were selected to receive bone ring grafting and immediate dental implant. Final fixed prostheses were cemented five months after initial implantation. Cone beam CT scans were conducted on all subjects before the procedure, as well as four months post-operation to evaluate alveolar bone height and level of bone height and absorption around the implants. Four to six months after prosthesis installation, each implant's Jemt classification, gingiva attachment, and probing depth (PD) were analyzed. The difference of PD between implants and adjacent teeth, as well as the difference of the bone absorption between labial and lingual sides, was compared. The survival rate of the bone ring and the retention rate of implants were calculated. Complications and patient satisfaction were also investigated.

RESULTSBone graft survival rate was 94.4% and dental implantation retention rate was 100% four months post-operation. Average bone level increase was (6.06 +/- 1.06) mm, average bone absorption was (1.33 +/- 0.84) mm, and average bone thickness at the neck of the dental implant body was (6.94 +/- 0.73) mm. Approximately 4 to 6 months after crown restoration, average bone level increase was (5.62 +/- 1.03) mm, average bone absorption was (1.51 +/- 1.02) mm, and average bone thickness at the neck of the dental implant body was (6.77 +/- 0.72) mm. The PD around the implant body and the adjacent teeth was statistically insignificant. No major post-operative complication was observed, restorations were successful, and patient satisfaction level was high.

CONCLUSIONBone ring graft technique and immediate dental implantation are relatively simple to perform, and these techniques facilitate reduction in required treatment time. Short-term effect is reliable and satisfactory, whereas long-term outcomes require further follow up and study.

Objective To investigate the expression and significance of the endocrine gland-derived vascular endothelial growth factor (EG-VEGF) and vascular endothelial growth factor(VEGF) in adrenocortical lesions of primary aldosteronism. Methods The expressions of EG-VEGF, and VEGF were detected by immunohistochemistry and real-time fluorescence quantitative PCR in samples of 18 cases of adrenocortical adenoma, 6 adrenocortical hyperplasia, and 8 normal adrenal cortex. The correlation between the expressions of EG-VEGF, VEGF, and clinicopathological parameters was analyzed. Results The expression of EG-VEGF or VEGF in adrenocortical adenomas was higher than that in adrenocortical hyperplasia or normal adrenal cortex ( all P＜0. 05 ), and the expression of EG-VEGF or VEGF between adrenocortical hyperplasia samples and normal adrenal cortex samples was indistinctive. There was no statistically significant correlation between EG-VEGF or VEGF expression and sex, age, blood pressure, serum potassium, plasma renin activity, except in case of serum aldosterone( P＜0.05 ). A positive correlation between EG-VEGF and VEGF ( P＜0. 01 ) was found. Conclusions EG-VEGF and VEGF may play a significant role in the formation and development of adrenocortical tumors in primary aldosteronism.
