Objective To investigate the executive function of children with different sports training. Methods Forty children with Ping-Pong training (Ping-Pong group) and 41 children with swimming training (swimming group), aged 6-9 years, completed GO/NOGO task. Behavioral data (reaction time and accuracy) and event related potential component N2 were collected and analyzed. Results The reaction time was significantly faster and accuracy significantly lower of GO task and NOGO task in swimming group than in Ping-Pong group (P<0.05 and P<0.01). There were significant differences in the amplitude of NOGO-N2 on site CPz between swimming group and Ping-Pong group[(-11.36±9.4) μV vs (-7.55±7.99) μV, P<0.05]. Conclusion The inhibitory function of children with Ping-Pong training is stronger than those with swimming training.

Objective To learn the prevalence and trends of Brucella disease in Ningxia, in order to provide scientific basis for effective control of the disease. Methods Data of Brucella cases reported through city network from 2004 to 2009 in Yinchuan city, Shizuishan city, Wuzhong city, Guyuan city and Zhongwei city of Ningxia were reviewed and retrospectively analyzed. The data included demographic characteristics, treatment conditions and medical history so on related information. Analytical indicators include reported incidence;with patients' gender, age, regional distribution, urban and rural distribution;become chronic and associated factors;distribution of the cases reporting unit and so on. Results From 2004 to 2009, Ningxia had reported 349 cases of Brucellosis, no deaths, the annual incidence rates reported were 0.017/10 million, 0.543/10 million, 0.151/101 (295/54);The proportion of 34- to 40-year-old age group was higher than other age groups(27.5%, 96/349);Occupational distribution of patients was mainly farmers and herdsmen(70.2% ,245/349), in regional distribution of the patients, the highest percentage was Wuzhong city(61.9%,216/349), followed by Yinchuan city(22.9%,80/349);The proportion of patients in rural areas(97.4% ,340/349) was higher than urban(2.6% ,9/349);the proportion of patients converted to chronic was 11.2% (39/349). With age, the chance of patients converted to chronic was in a decreasing trend(odds ratio was 0.966);cases reported by Centre for Disease Control and Prevention accounted for 74.8%(261/349), by hospital accounted for 25.2%(88/349). Conclusions The reported incidence of Brucellosis in Ningxia is in a rapid upward trend year by year, the patients is mainly young men, the rate of converted to chronic is higher and the ability of hospital in founding and reporting of the cases is weaker.Comprehensive measures should be taken to increase funding, strengthen monitoring, and continuously improve the level of awareness and diagnosis of medical personnel for further strengthen the prevention and control of Brucellosis.

Chinese patent medicine with double identity was a special phenomenon, and many preparations not only were prescription drugs but also over the counter ( OTC) drugs, which brought a lot of trouble. Based on statistics of list of OTC medicines of CFDA, related varieties, route of administration and functions of these drugs were searched. The causes of insufficient were analyzed and the potential risk was investigated. To ensure the safety of drug usage for the patient, risk management system should be set up by improving the technical requirements for registration, improving the drug labels and manuals, playing the role of pharmacists in pharmacy services and raising awareness of doctor and patient for these drugs.

BACKGROUND: Experimental autoimmune encephalomyelitis has become the most classical animal model for multiple sclerosis. However, the experimental autoimmune encephalomyelitis model of China presented one-way course of disease. By using proteolipid protein 139-151 and proteolipid protein 178-191, relapse remitting experimental autoimmune encephalomyelitis models may be induced in SJL/J mice which were susceptible to immune, which have similar clinical situation, course and histologicallterations to multiple sclerosis.OBJECTIVE: To establish the relapse remitting experimental autoimmune encephalomyelitis mouse model induced by proteolipid protein, which has similar clinical situation, course and histological alterations to multiple sclerosis.DESIGN: Completely randomized controlled study.SETTING: The centre of Neuro-information, and Neurological Institute,General Hospital of Chinese PLA.MATERIALS: The study was carried out at the Laboratory of Neuro-pathology, General Hospital of Chinese PLA, from February to June 2004.Sixty female SJL/J mice with 8-12 weeks old were selected and randomly divided into proteolipid protein 139-151 group and proteolipid protein-178-191 group with 30 in each.INTERVENTIONS: After injected with proteolipid protein-139-151 or proteolipid protein-178-191, the models of relapse remitting experimental autoimmune encephalomyelitis were induced, and the body weight and neurological signs of each female SJL/J mouse were viewed. The tissue morphological changes of models were observed with hematoxylin and eosin and uxol fast blue stain.MAIN OUTCOME MEASURES: The neurological symptoms and signs,features of relapse and remitting and the perivascular inflammatory cell infiltration, demyelinated lesion of the model of experimental autoimmune encephalomyelitis mouse induced by two proteolipid protein peptides.RESULTS: All 60 mice entered the final analysis. ① Significant neurological symptoms, signs and features of relapse and remitting was manifested in the model of experimental autoimmune encephalomyelitis mouse induced by two proteolipid protein peptides. Obvious phenomena of perivascular inflammatory cuffing, satellitism, predominant perivascular inflammatory cell infiltration and demyelinated lesion were found in spinal and cerebral tissue. ②Changes of body mass: Before immunity, the body mass of mice in two groups was( 17. 84 ± 2.59) g and (17. 88 ± 0.52) g respectively. Onset of relapse of the mice in proteolipid protein-178-191 group was earlier and faster, their body mass had no distinctive change after immunization and the mean body mass was(23.52 ± 2.37) g till the 60th day. Meanwhile, Onset of relapse of the mice in proteolipid protein-139-151 group was later and slower. After the immunity, the body mass of mice was little decrease, and the body mass was (16. 70 ±0.46) g on the 60th day. ③ Neural functional scores: The highest functional scores in the two groups were not different(3.86 ± 1.10vs 3.71 ±1.05, t=0.49, P=0.628).CONCLUSION: The two different antigenic peptides of proteolipid protein can all cause the autoimmune response of central nervous system. Both models have the same characters of relapse and remitting and the severity has no significant difference. But compared with proteolipid protein 139- 151 group,onset and recover of the experimental autoimmune encephalomyelitis of the mice in proteolipid protein 178-191 group were earlier, as well as weight variance was larger, which maybe due to the different structure of two peptides.

Objective To investigate the tissue remodeling and cell alignment of TDBM scaffolds seeded with rabbit tenocytes under the cycle dynamic tensile force or static tension-free culture in vitro. Methods TDBM were made by ourselves, and uniaxial cyclic tendon stretching device was designed and manufactured on our own. Primary tenocytes were isolated from the Achilles tendon of three-day-old New Zealand white rabbits and seeded into scaffolds, and were cultured collectively in DMEM in vitro. Samples were divided into two groups:dynamic tension-loaded group, and static tension-free group. Fresh natural tendons were used to be positive control. The experiment's time was six weeks. The scaffold-cell complexes were harvested at 3 and 7 days of culture for Inverted microscope and scanning electron micrograph (SEM) analysis. The morphological characters of the samples, including the general view, HE and Masson's dyeing, were observed at 2, 4 and 6 weeks. In addition, the gene expression of the I-type collagen and III-type collagen of the samples was detected by using Real time PCR at every week. Set fresh natural tendon as control. Results The inverted microscope and SEM showed that it was nice compatible condition between the tendon cells and TD-BM scaffold. In addition, the tendon of tension-loaded group revealed a structure of longitudinally aligned collagen fi bers and dense structure of collagen fibers arranged in orderly form a unique corrugated structure. Tenocytes layer located between the col-lagen fibers and aligned longitudinally along the force axis, with increased matrix deposition after the 3th week showed by RT-PCR. The cell/matrix ratio decreases. When cultured to 6 weeks, the tissue structure was very similar to that of fresh natural ten-don pattern. By contrast, HE and Masson's staining revealed the collagen fibro-tissue structure in tension-free groups with disorga-nized matrix structure and randomly distributed cells. Collagen fibers were gradually degraded with time. In tension-loaded group, Real-time PCR showed that gene expression of I-type collagen and III-type collagen gradually increase, but in tension-free group, the relative gene expression of I-type collagen and III-type collagen was highest at 3rd week, and from that time the relative expres-sion gradually decrease. Conclusion Under the dynamic stress, the TDBM scaffolds seeded with rabbit tenocytes can promote extra-cellular matrix biosynthesis and tendon structure remodeling, which is a promising method for tendon tissue engineering.

5 fold) were noted.Six significant differential proteins in gel were identified by LTQ-ESI,e.g.endoplasmin precursor,acidic leucin-rich nuclear phosphoprotein 32 family member A,serotransferrin precursor,stress-70 protein precursor,fibronectin precursor,complement C3 precursor,fibrinogen gamma polypeptide.CONCLUSION: The protein profile of apoE-/-/LDLR-/-mouse liver exhibits significant difference compared to that of WT mice.The results imply that lipid metabolism relative polygenetic mutation contributes to the alteration of mouse liver protein expression profile,especially that lipid metabolism related perhaps participates in dysfunction in lipid metabolism during atherogenesis.

The results show that there are 1.728 (0. 195 -4.225)?104cfu/g (fw) bacterial endophytes in the variety of mangroves, the most population of the endophytic bacteria was found in Rhizophora stylosa, the figure was4. 225?104cfu/g (fw) , the next was Bruguiera gymnorrhiza, Aegiceras corniculatum, Kandelia candel and Avicennia marina. In parts of the mangroves, the contents of the bacteria in stem was the most, the figure was 1. 649?10 cfu/g (fw) , then the root and the leaf. Of the bacteria, about 43. 53% strains expressed the antagonism against the growth of the plant pathogens, such as Fusarium oxyspontm f. sp. cubense , Colletotrichum sp. and Rahtonia solanaceance etc. and these bacteria were identified as Bacillus sp. . The results also showed that 9 of the 13 strains (69. 23% ) could promote the growth of the tomato, while 4 strains (30. 77% ) restrained the tomato's growth.

OBJECTIVETo investigate the anatomic feature of pudendal-thigh flap and to provide anatomic guide for clinical design and application of the flap in repairing and reconstructing male perineal region.

METHODSThe clinical anatomy of blood supply and refluence and nerve innervation of the perineal region in 15 male cadavers (30 sides) were investigated. Then reasonable flaps were designed for male patients needing repair and reconstruction of the perineal regions based on the anatomic findings.

RESULTSPerineal region has adequate arterial blood supply, abundant venous refluence and reliable nerve innervation. The area has multi-source blood supplies: external pudendal artery, anterior cutaneous branches of obturator artery, bole and lateral branch of arteriae scrotales posteriores. The locations of the arteries were mainly uniform in the 30 sides. Three vasoganglion composed by these arteries and their branches connecting superior, central and inferior parts of the flap. In the 23 cases, the largest flap was 17 cm x 9 cm, and the smallest was 8 cm x 5 cm. The flaps survived and recovered well, with perfect appearance and sensation. The patients were all satisfied with the operation results.

CONCLUSIONSThe pudendal-thigh flap has abundant blood supply. It can be incised conveniently and covers donor sites well. The flap can be used to repair and reconstruct male perineum with ideal appearance and sensation.
