The high frequency subject headings were extracted from papers published in Journal of American Medi-cal Informatics Association from 2006 to 2015 to form a matrix of high frequency subject headings and their source papers. The co-occurrence of high frequency subject headings in a paper was clustered and analyzed, which showed that studies in Journal of American Medical Informatics Association from 2006 to 2015 were focused on the design and development of clinical software or platform, application of data mining in medical field, and clinical decision-making support system.

11.1mmol/L were treated by 2 weeks CSⅡ.The elements of 2 hours postprandial,insulin,C-peptide, HbAlc,HOMA-?,and HOMA-IR were analyzed and compared before and after treatment,and the control of post- prandial of patients for 2 years was observed.Results The excellent control of FPG and 2h PG in 36 patients were achieved stably in(5.6?0.4)mmol/L and(8.2?1.4)mmol/L below the condition of(13.6?1.5)mmol/L and (20.1?4.0)mmol/L before treatment(P

ObjectiveTo investigate the variation of thalamus metabolism in patients with multiple sclerosis (MS) or neuronmyelitis optica (NMO) using 1H-MRS.Methods1H-MRS was performed to 32 MS patients (MS group),28 NMO patients (NMO group) and 35 healthy volunteers (normal control group).The ratios of metabolism in thalamus,including N-acetylaspartic acid/creatine (NAA/Cr),choline/creatine (Cho/Cr) and myo-inositol/creatine (mI/Cr) were calculated and compared.ResultsThere was statistical difference of NAA/Cr in thalamus among the three groups (P＜0.05).NAA/Cr in thalamus of MS group was significantly lower than that of normal control group (t= -3.45,P＜0.05),while no statistical difference of Cho/Cr and mI/Cr was found (t=0.086,0.661,all P＞0.05).No statistical difference of NAA/Cr,Cho/Cr or ml/Cr was found between NMO group and normal control group (t=-0.792,1.408,1.735,all P＞0.05).Conclusion1H-MRS shows the decrease of thalamus NAA/Cr that suggesting axon damage in MS patients,but in NMO patients no same result is found.1 H-MRS can reflect the pathological changes of MS and NMO,and improve the differential diagnosis of the two diseases.

Objective To investigate the efficacy of transverse insertion of thick needles into the Du meridian in treating rat ischemic facial paralysis and preliminarily explore the possible mechanism by which it produces a therapeutic effect. Methods Sixty Wistar rats were randomly allocated to groups A (transverse insertion of thick needles), B (basic Western drugs), C (blank control) and D (sham operation), 15 rats each. A rat model of ischemic facial paralysis was made using a modified vascular occlusion method in all the rats. Facial nerve deficits were scored in every group of rats during treatment. At 1 day after model making, group A was treated by transverse insertion into point Shendao and 4-hour retention of needle, once daily, for a total of 14 days; group B was treated by an oral gavage of prednisone and intraperitoneal injection of vitamine B12, once daily, for a total of 14 days. Groups C and D were not treated. In 4 rats randomly chosen at 3, 7 or 14 days after model making, facial nerve concomitant intrinsic vascular tissue HIF-1αprotein was measured by an immunohistochemical method; serum NO, by enzyme-linked immunosorbent assay; serum ET content, by radioimmunoassay.Results After 7 days of treatment, the neurological deficit score increased gradually in groups A and B and there was a statistically significant difference compared with after model making in the two groups (P<0.01). After 7 days of treatment, there was a statistically significant difference in the neurological deficit score in groups A and B compared with groups C and D (P<0.05) and between groups C and D (P<0.05). After 14 days of treatment, there was a statistically significant difference in the neurological deficit score between group A or B and group C (P<0.05) and between group B or C and group D (P<0.05). In group A, there was a statistically significant difference in the neurological deficit score after 14 days of treatment compared with after 7 days of treatment (P<0.05). After 3, 7 and 14 days of treatment, there was a statistically significant difference in HIF-1αMOD value in groups A , B and C compared with group D (P<0.01). After 3 and 7 days of treatment, there was a statistically significant difference in HIF-1αMOD value between group A or B and group C (P<0.05). In groups A and B, there was a statistically significant difference in HIF-1αMOD value after 3 and 14 days of treatment compared with after 7 days of treatment (P<0.05). After 3 and 7 days of treatment, there was a statistically significant difference in serum NO content between group A or B and group D (P<0.01). In groups A and B, there was a statistically significant difference in serum NO content after 7 days of treatment compared with after 3 days of treatment (P<0.05). After 3 and 7 days of treatment, there was a statistically significant difference in serum ET content in groups A , B and C compared with group D (P<0.05). In groups A and B, there was a statistically significant difference in serum ET content after 7 days of treatment compared with after 3 days of treatment (P<0.05).Conclusions Transverse insertion of thick needles into the Du meridian can effectively promote rat’s recovery from ischemic facial paralysis. The mechanism by which it produces a therapeutic effect may be regulating the expression of tissue HIF-1α and the NO and ET contents of serum.

To evaluate the neuroprotective effect of nerve growth factor ( NGF ) on acute angle-closure glaucoma patients after trabeculetomy.METHODS: Patients with viral keratitis who underwent trabeculectomy in treatment of acute angle - closure glaucoma in Xiamen Eye Center of Xiamen University from December 2011 to October 2013 were selected and completed the treatment, 61 eyes of 45 cases were followed up. The treatment group of 23 cases (32 eyes) with acute angle-closure glaucoma patients were treated by NGF gel for 3mo after trabeculetomy, while in the control group 22 cases (29 eyes) were treated by normal saline replaced NGF. All patients were followed up for at least 12mo, visual acuity, perimetry, retinal nerve fiber layer ( RNFL) thickness and cup/disc ratio of the patients were followed up during the treatment. The safety of topical use of NGF gel was also evaluated.RESULTS:ln all patients, the intraocular pressure ( lOP) was successfully controlled under 21mmHg and the visual acuity was markedly increased in the affected eye after trabeculectomy. Compared with control group, the postoperative lOP and visual acuity had no significant differences in treatment group (P>0. 05). The average light sensitivity of perimetry and mean defect were better than that in control group postoperative 6 and 12mo; The results of optical coherent tomography ( OCT ) and Heiderburg Retina Tomography ( HRT )-Ⅲ showed that RNFL thickness was significantly greater than that in control group, while cup/disc ratio significantly less than that in control group postoperative 6 and 12mo. Ocular surface damage, corneal endothelium to reduce and other eye complication were no observed in treatment group.CONCLUSlON:Acute angle-closure glaucoma treated by NGF gel after operation is effective and safe.

OBJECTIVETo study the protective effects of polysaccharide of Spirulina platensis and Sargassum thunbeergii on vascular of alloxan (ALX) induced diabetic rats.

METHODWith the doses of polysaccharide of Spirulina platensis (PSP) and Sargassum thunbeergii (PST) compound (1:1) 12.261, 36.783, 110.349 mg x kg(-1) by i.g. administration to alloxan induced diabetic rats respectively for 6 weeks. Then the blood glucose and the TC, HDL-C, TG, NO, ET in serum were detected. The contraction and relaxation response to NE and ACh in aortic rings of the alloxan induced diabetic rats has been studied.

RESULTThe results showed the compound of PSP and PST could decrease the blood glucose and the TC, TG, NO, ET in serum and increase HDL-C than in the alloxan induced diabetic rats. The contraction responses to NE in aortic rings of the alloxan induced diabetic rats were significantly elevated in the normal rats, and the responses to ACh were significantly lower. PSP and PST compound could significantly lower the responses to NE and significantly elevate the responses to ACh in aortic rings of the alloxan induced diabetic rats.

CONCLUSIONPSP and PST compound could decrease blood glucose and could protect the vascular of alloxan induced diabetic rats.
