Objective To compare the differences of cognitive dysfunction and hippocampal atrophy among patients with temporal lobe epilepsy (TLE) and healthy controls and probe into the relativity of cognitive dysfunction with hippocampal atrophy after temporal lobe epilepsy. Methods Forty-nine TLE cases and 20 healthy individuals were randomly selected. The WAMS-R and WAIS-R scales were adopted to assess the memory and intelligence of all the subjects. Hippocampal volumes were measured by semiautomatic measurement on the head magnetic resonance imaging (MRI). The degree of hippocampal atrophy (DHA) and asymmetry index (AsI) were caculated by adjusting hippocampal volumes and ratio of difference of two lateral hippocampal volumes. Results Compared with the healthy controls, not only did the TLE patients exhibit more memory deficits (83.2±21.0,t=-3.365 ,P=0.001 ), but also more fullscale intelligence (91.0±12.3, t=- 4.291, P=0.000). The bilateral hippocampi of all TLE patients significantly decreased in volume ( P=0.000 ) and increased in AsI ( t=3.975, P=0.000 ). The MQ of TLE patients was significantly negatively related to the duration of the illness ( r=-0.339, P=0.017 ). The bilateral DHA and the hippocampal AsI were negatively related to Z scores (left: r=-0.297, P= 0.038, right: r=-0.305, P=0.033, AsI: r=-0.441, P=0.002), repectively. Conclusions The more the DHA and asymmetry of bilateral hippocampi, the worse the cognitive dysfunction. The quantitative measurements of hippocampal volume could be used as a clinically effective factor for evaluating the decrease of the intelligence of TLE patients.

Digitalization of ancient medical documents has become an important platform for the development and protection of medical literature and digitalization of ancient medical documents based on ancient medical documents themselves will lead to a series of intellectual property rights. After the relationship between ancient medical docu-ments and protection of intellectual property rights was analyzed, the major intellectual property rights involved in current digitalization of ancient medical documents were pointed out with their solutions elaborated from the reasona-bleness, rationality, legality and normality.

Objective To investigate the current situation of maternal self- efficacy of breastfeeding and explore its influencing factors in Zhengzhou. Methods Using the general condition questionnaires, breast feeding self-efficacy scale, perceived social support scale and Edinburgh postnatal depression scale to assess the situation of 180 puerperas by the convenience sampling in one obstetric hospital of Zhengzhou. Results The total score of maternal breast feeding self-efficacy was(114.04 ± 21.57)points.The frequency of delivery, the way of delivery and feeding ways, the average income of family were effected with breastfeeding self-efficacy. The total score of social support was(68.87 ± 10.43) points, the total score of puerperas depression was(7.61 ± 4.25) points.The social support score had positive correlation with breastfeeding self-efficacy(r=0.423, P<0.01). Puerperas depression had negative correlation with breastfeeding self- efficacy(r=- 0.342, P<0.01). Conclusions The maternal breastfeeding level in Zhengzhou was at a lower level. The level of maternal breastfeeding self-efficacy scale was impacted by maternal social support degree, the degree of depression. Measures should be taken to enhance maternal social support degree, reduce the degree of depression, in order to improve the level of maternal breastfeeding self-efficacy.

Aim To observe the effect of Guishao-tongluo ( GSTL ) on the angiogenesis of vasa vasorum and oxidative stress in the early stage of atherosclero-sis. Methods The rabbits ( n =84 ) were randomly divided into 7 groups (n=12):control group,high-fat group, adventitial injury group, GSTL high(GH)and medium ( GM ) dose group, atorvastain group ( ATO ) , and Tongxinluo group ( TXL ) . The normal group was fed with common foodstuffs, and high-fat foodstuffs for the high-fat group to establish an early model of hyper-lipidemia, and all the other groups were fed with high-fat diet combined with carotid artery cannula to build early atherosclerosis carotid artery injury rabbit mod-els. The GSTL high and medium dose was given Guishaotongluo ultrafine powder 4. 16,2. 08 g·kg-1 · d-1 respectively. The atorvastain group and Tongxinluo group were given suspension of atorvastain solution 2. 5 mg·kg-1 ·d-1 , Tongxinluo supermicro powder 0. 6 g ·kg-1 ·d-1 . All groups were treated with gastric per-fusion for 4 weeks. Biochemical method was applied to detect blood lipid change. HE staining was used to ob-serve the pathological morphology of intima-media. Aactivity of serum superoxide dismutase( SOD) ,malon-dialdehyde ( MDA ) content and the total antioxidant capacity ( T-AOC ) in artery serum were detected. NADPH subunits p22phox mRNA, gp91phox mRNA in carotid arteries were located and semi-quantitated by fluorescence in situ hybridization. The expression of VEGF, VEGFR-2 in the carotid artery adventitia was detected by Western blot. Results Compared with normal group,the contents of TC,TG and LDL-C were significantly increased, and VEGF, VEGFR-2 protein levels were remarkly increased in high-fat and adventi-tial injury group. The carotid artery injuries,the degree of angiogenesis of vasa vasorum and NADPH subunits p22phox, gp91phox mRNA in adventitia tissue of the GH,GM, ATO and TXL group were milder in varying degrees compared with those of the vasa injury group. Also the activity of SOD,T-AOC increased,while MDA content,VEGF,VEGFR-2 protein levels were remarkly decreased ( P < 0. 5 or P < 0. 01 ) . Conclusions GSTL can inbibit adventitial neovascularization in the early stage of atherosclerosis, and its mechanism might be related to the increase of total antioxidant capacity of the vascular system and adventitia tissue.

Gut microbiota(GM)consists of a complex community of microorganism species that live in the digestive tracts of animals including humans. Dysbiosis is believed to involve in the development of some diseases. Recently dysbiosis in the patients with Alzheimer′s disease(AD)and AD rat models was reported. GM may influence the pathogenesis and development of AD in several ways. Some neurotoxic substances produced by GM can invade into the brain via circulation and impair the neural functions. These sub?stances include ammonia,cyanobacteria-producedβ-N-methylamino-L-alanine,saxitoxin,anatoxin-αand amyloid. The decrease in brain-derived neurotrophic factor(BDNF)in hippocampus and cerebral cortex induced by dysbiosis contributes to the cognitive dys?function. Dysbiosis related endotoxin can induce inflammation,which is one important risk factor for obesity,insulin resistance(IR) and type 2 diabetes mellitus(TIDM). AD and diabetes have good correlation and similarity. Probiotics,prebiotics and Chinese herbal medicines can rebuild GM and have been reported to ameliorate the memory loss of AD patients or model rats. However ,whether and how their preventative and therapeutic effects on AD mediated by GM are worthy of further investigation.
