Objective To study the relationship between CXXC motif and biologic activity of human augmenter of liver regeneration protein(hALRp).Methods The function of CXXC motif and its relationship with bioactivity were investigated between hALRp and hALRp-C65A groups by detecting the sulfhydryl oxidase activity;the interaction of target protein with GST-Na~+,K~+-ATPase fusion protein was examined by GST-Pulldown and MTT was used to study the ability of hALRp-C65A to promote HL-7702 hepatic cells proliferation in vitro.Results The turnover number(TN) of hALRp in sulfhydryl oxidase activity assay was 1.25?0.21,while TN was 0 of hALRp-C65A,there was significant difference between them(P

Objective　To observe the change of lipidemia and lipoprotein in wistar rats with fluorosis.Methods　14 wistar rats were fed normal food with hyper concentration of NaF water (100 mg/L) for six months,the TC,TG,HDL-c,LDL-c,APO AI APO B and AI,R-CHE were measured in serum.Results　The result show that there are an increace of T C,TG,HDL-c,LDL-c,APO AI，APO B and AI,R-CHD compared with normal rats (P <0.05).Conclusions　The result indicate that the fluorosis can increase the lipidemia and lipoprotein in rats with fluorosis and lead to athero selerosis.

microRNA (miRNA) is a class of endogenous non-coding small RNAs,they play an important role in post-transcriptional regulation of gene expression through combining the target mRNA that the target protein would not synthesis.The present studies have found that miRNA is involved in many kinds of physiological processes,as well as the pathological processes.The abnormal expression of miRNA in many diseases can be used in diagnosis,prognosis and treatment monitoring.But all of these studies depend on an ideal detection method of miRNA.A lot of detection methods of miRNA expression developed from qualitative analysis to quantitative analysis step by step and from single miRNA detection to high throughput screening in recent years.Various detection methods are improved constantly,the specificity and sensitivity has been improved at the same time,detection procedure become simple and practicable,detection time shorten considerably and cost also reduced ceaselessly,which make the application of miRNA in clinical possible.This review highlights the latest research progress of the common detection methods of miRNA.

Objective　To analyze the advantages of intracrani al hematoma smash puncture (IHSP) in the treatment of cranial hemorrhage for the elderly. Methods　A total of 104 cases of cerebral hemorrhage a dmitted in the recent 3 years were collected and divided into 4 grou ps, i.e . group A, elderly with IHSP treatment (n=36), group B, elderly with regular medical treatment (n=33), group C, non-elderly with IHSP treatment (n= 21) and group D, non-elderly with routine therapy (n=14). The clinical and follow-up outcomes were studied and analyzed. Results　There w as significant difference in rehemorrhage rate after puncture between grou p A (0/36) and group C (2/21). Significant difference was found in early mortali ty rate in group A (16.67%) and group B (39.40%). The rate of activity of daily living (ADL) 1-2 was significantly higher in group A (58.62%) than group B (5.88 %)(P<0.005) and that of ADL 4-5 was obvious lower in group A (13.79%) than g roup B (47.06%)(P<0.025). Conclusion　Intracranial hematoma smash hemorrage is safe and efficient in the treatment of elderly cerebr al hemorrhage, especially in reducing the disability rate.

?AIM: To study the changes of choroidal thickness and hemodynamic parameters in patients with diabetic retinopathy and their influencing factors.?METHODS: From January 2013 to January 2015, 100 patients (100 eyes) with type 2 diabetes were divided into 3 groups:34 patients without diabetic retinopathy ( NDR) , 36 patients with non proliferative diabetic retinopathy ( NPDR) group, and 30 patients with proliferative diabetic retinopathy (PDR). According to the results of OCT, the patients with diabetic retinopathy were divided into 2 groups: diabetic macular edema ( DME ) group ( 28 cases) , and 38 cases without diabetic macular edema. During the same period in our hospital 35 subjects for physical examination were selected as the control group. The hemodynamic parameters of the posterior ciliary artery in different groups of patients at different distance from the center of the macular were compared, analyzing influencing factors.?RESULTS:With the aggravation of diabetic retinopathy, the choroidal thickness in different distance from the center of the macular decreased. The choroidal thickness of NPDR and PDR group were thinner than that of the control group (P<0. 05). The choroidal thickness of NDR group was not different from the control group (P>0. 05). There was no significant difference in the choroidal thickness between the DME patients and non DME patients (P>0. 05). Pearson correlation analysis showed that there was no significant correlation between choroidal thickness of patients with diabetic retinopathy and diabetic duration, fasting blood glucose, HbA1c, eye axis length, systolic blood pressure and diastolic blood pressure (P>0. 05), but there was a correlation with BCVA (logMAR) (P<0. 01). EDV and PSV in NDR group and NPDR group were significantly lower than those in control group, RI was higher than that in control group. PSV and EDV in PDR group were significantly lower than those in other three groups, RI was higher than the other three groups, and the difference was statistically significant ( P<0. 05).?CONCLUSION:With the severity of retinopathy in type 2 diabetic patients, the choroidal thickness decreased, and the thickness of the choroid is beneficial in the comprehensive analysis of 2 diabetic retinopathy.

Angiogenesis after cerebral ischemia iS increasingly receiving attention.The expression of angiogenesis growth factor increases after cerebral ischemia.It promotes endothelial proliferation and neovascularization,and thus improves blood supply in ischemic regions and decreases the volume of infarction.The combination of exogenous angiogenesis growth factor.stem cell transplantation and therapeutic angiogenesis to promote angiogenesis was mainly achieved by promoting the expression of angiogenesis growth factor."Ihe further study of the mechanism of angiogenesis after ischernia will provide theoretical basis for the treatment of ischemic stroke.
