Technologies for the trans-institutional sharing of scientific data were studied with the sharing of nucleic acid sequence data as the study object , such as leaving a flexible space for implementation of the unified standards in working out the criteria for data sharing , implementing regular point to point data sharing and updating in agree-ment of institutional league , and providing multiple data services according to the unified working process by giving considerations to the local demands .The significance of trans-institutional sharing of scientific data under the insti-tutional league model was summarized for the reference in constructing the scientific datasharing platform.

The relationship between medical practitioners and padtients always changes with time and this shift becomes quite striking nowadays.The characteristics and underlying reasons of this trend are expounded from such aspects as the changes in medical service system,the alteration in definitions of medical practitioners and patients, the advent of market economy.It is precondition and guarantee of handling the relationship properly to consummate relevant laws and codes,establish medical insurance institution,classify hospitals and set moral restraint for both medical practitioners and patients.

The paper focuses on precision medical initiatives of China,the United States and Britain.It outlines their main aims and tasks,and compares the implementation,data management and sharing of initiatives.Some enlightenment is summarized to provide references for China to carry out national key research,and development program of precision medical research.

Objectives To study a special pattern of electroencephalogram (EEG),regional attenuation without Delta in massive cerebral ischemic infraction and evaluate its clinical value.Methods All the 47 cases diagnosed as massive cerebral infraction were continuously observed and evaluated in the period of 2004 to 2006 for EEG,short-latency somatosensory evoked potential (SLSEP).Glasgow coma scale (GCS) and the National Institutes of Health Stroke Scale (NIHSS) were also rated.EEG monitoring was performed every 1 to 3 day,but at least one time for patient with deteriorated condition.The outcome was evaluated with Glasgow outcome scale (GOS).Results 47 cases were performed 70 times of EEG all together,among whom 32 cases (68.1%) showed RAWOD in EEG.The positive rate of RAWOD was 76.9% within 24 hours of onset,but it was 28.6% in CT in the same time.The GCS and NIHSS of two groups had significant differences (P

Objective To study characteristics of clinical manifestation of patients with acute myocardial infarction (AMI).Methods From 1999 to 2002,the risk factors,symptoms,signs,and results of assistant check of 97 patients with AMI were analyzed.They were divided into thrombelytic group and control group.Results (1) The main risk factor are hypertention,smoking and diabetes.(2) There was no difference in complication of AMI between two groups.Thrombolytic group has higher curing rate.Conclusion AMI patients without contraindication should be treated by thrombolytion in time.

Background Familial vitreous amyloidosis is a rare ocular regional amyloidosis,and it is a kind of autosomal dominant inheritance disease.Familial vitreous amyloidosis demonstrates a variable penetrance due to the mutation in the plasma thyroid hormone-binding protein transtheretin (TTR) gene.Many studies have reported over 100 types of TTR genetic mutation in Switzerland,Portugal and Japan,but rare in China.Objective This survey aimed to investigate the clinical and genetic mutation characteristics in familial vitreous amyloidosis.Methods Physical and eye examinations were performed on 52 family members of this vitreous amyloidosis family.Peripheral blood samples from 52 members were collected for TTR gene test by DNA extract,PCR amplification,clone,bolting and sequencing.Pars plana vitrectomy was firstly performed prior to the pathological examination of vitreous sample on 13 eyes of 8 members.Informed consent was obtained from each individual before any medical procedure.Results Seventeen members suffered from vitreous amyloidosis in this family without nervous system,heart,kidney and liver disease.Vitreous opacity was found in 34 eyes of the 17 members,and retinal vasculopathy was seen in 28 eyes of 15 members.In addition,cataract appeared in 16 eyes of 10 members.None of the members had glaucoma or ocular motility disorders.Congo red test of vitreous specimens showed a positive result in 13 eyes of 8 patients who received vitrectomy.Point mutation was verified on the 83th amine acid location of exon 3 (Gly83Arg) in TTR gene by gene sequencing.Conclusions Clinical characteristics of familial vitreous amyloidosis induced by TTR gene Arg-83 mutation is rate retinal vasculopathy without glaucoma,other ocular regional disease and systemic diseases.

Objective:To investigate the mechanism of miR-128 on the expression of AK2 protein through the STAT3 signaling pathway on the biological behavior of cervical cancer cells .Methods: The expression of AK2 and miR-128 in cervical cancer tissues and cells was detected by qPCR and Western blot .Double luciferase assay was used to detect the interaction between miR-128 and AK2.CCK-8 proliferation assay was used to detect the effect of miR-128 on the enhancement of cervical cancer cells .The effect of miR-128 on the tumorigenesis of cervical cancer cells was exa mined by tumor formation test in nude mice .Western blot was used to detect the effect of miR-128 on STAT3 signal pathway protein level .Western blot was used to detect the inhibitory effect of miR-128 on p-STAT3 by overexpressing AK2 protein.Results:The expression level of AK2 in cervical cancer tissues was higher than that in normal cervical tissues,and the expression level of miR-128 in cervical cancer C33a cells was lower.Double luciferase assay confirmed that miR-128 could directly target the expression of AK 2.CCK-8 proliferation test showed that miR-128 could inhibit the proliferation of cervical cancer cell lines .In vivo tumorigenesis test showed that the increase of miR-128 could inhibit the tumorigenesis ability of cervical cancer cells[volume(3.05±0.35)cm3 vs (0.86±0.11)cm3,P=0.031;weight(3.26±0.39)g vs (0.89±0.15)g,P=0.016 ];Western blot showed that miR-128 could inhibit the activation of p-STAT [ ( 42.12 ±6.28 )% vs ( 91.25 ±9.29 )%, P<0.05 ] ,while the overexpression of AK 2 could reverse the inhibitory effect of miR-128 on p-STAT.Conclusion: miR-128 is used to regulate the expression of AK 2 and regulate the biological behavior of cervical cancer cells through the activation of STAT 3 pathway.
