Objeetive To observe the effect of the fire and leopard-spot needling therapy in treating ankle sprain.Methods We randomly selected 59 ankle sprain cascs and divided them into 2 groups,with one contained 30 cases treated hy fire and leopard-spot needling therapy as the treatment group,and another contained 29 cases treated by computerized multa-function therapy apparatus as the control group.After 7 days'treatment,we observed the effects of each group.Results The results snowed that the effect of the treatment group was much better than the control group.Conclusion With the features of collateral vessel pricking and warming and activating meridians,fire and leopard-spot needling therapy can remove swelling and relieve pain rapidly.

Objective:To analyze the effect of first aid knowledge and skills training for women in poverty-stricken areas, and summarize the importance of first aid knowledge and skills for women in poverty-stricken families.Methods:By cluster sampling, 318 women from poverty-stricken families who participated in the vocational training class in Zhen’an County, Shaanxi Province were trained in first aid knowledge and skills. The mastery of first aid knowledge before and after the training was evaluated by questionnaire survey, and the mastery of first aid skills before and after the training was evaluated by on-site assessment.Results:After the theoretical training of women from poor families, the awareness rate ranked in the top five were fire, poisoning, burns, heatstroke and earthquake first aid measures, with a knowledge rate of 98.1%(312/318),96.5%(307/318), 95.3%(303/318), 93.4%(297/318), 91.8%(292/318), which were statistically different from the pre-training rate, 88.0%(280/318), 84.0%(267/318), 78.4%(249/318), 43.4%(138/318), 72.6%(231/318), ( χ2 value was 15.03-183.89, all P<0.01). The pass rate of post-training cardiopulmonary resuscitation, hemostatic, dressing, and carrying skills of poor family women were 69.8% (222/318) , 52.8% (168/318) , 50.0% (159/318) , 76.1% (242/318) , respectively, which were statistically different from pre-training, 1.3%(4/318), 2.2%(7/318), 1.9%(6/318), 6.9%(22/318), ( χ2 value was 191.57-326.19, all P<0.01). Conclusion:The effect of training on first aid knowledge and skills of women in poverty-stricken families is significant, and a long-term training mechanism can be established.

To explore the relativity between alexithymia and cognitive function in somatoform disorder patients.A total of 40 patients aged 18-65 years fulfilling the criteria of ICD-10 for somatoform disorders were recruited as research group.And 40 normal healthy subjects were selected as control group.Toronto alexithymia scale-20 (TAS-20) was employed to examine the alexithymia.And cognitive abilities screening instrument (CASI) was used to measure their cognitive ability.The 9-factor scores and total score of CASI test in patients with somatoforill disorder were significantly lower than those in the normal controls (P ＜ 0.05 or ＜ 0.01).The 3-factor scores and total score of TAS-20 test in patients withsomatoforill disorder were significantly higher than those in the normal controls (P ＜ 0.05 or ＜ 0.01).In research group,CASI scores were negatively correlated with the TAS-20 scores (P ＜0.05 or 0.01).

Objective:To explore the central mechanism of working memory impairments experienced by patients with schizophrenia.Methods:Using block-design,ten normal and twenty patients with schizophrenia perform digital recognition(remember two or five digitals simultaneous and make judgment about whether the digital presented latter is that appeared before)and direction judgment of arrows(toward to left or right)while proceeding blood-oxygen level dependent contrast functional magnetic resonance imaging(BOLD-fMRI).Results:On the condition of same cognitive load,abnormal activation of basal ganglia occurred in schizophrenics.Comparing to normal control,patients with schizophrenia exhibited a tendency of more activation in dorsolateral prefrontal cortex.Conclusion:Abnormal activity of basal ganglia and dorsolateral prefrontal cortex may be the critical cause of working memory deficit experienced by patients with schizophrenia.

Objective To study the inter-allelic recombination event occurring in the HLA-C locus in a family of Chinese Han nationality, and to evaluate the molecular genetic background of the new HLA allele.Methods Peripheral blood samples were collected from a Chinese leukemia woman patient, as well as her healthy parents and two brothers.HLA-A, C, B, DRB1 and DQB1 alleles were typed by high-resolution PCR-sequence-based typing (SBT) method using Atria Genetic AlleleSEQR HLA SBT kits.The Protrans S4 HLA-C single allele-specific sequencing strategy was used to separate the two HLA-C alleles and to determine novelty of the allele.The full length sequences of HLA-C alleles of the patient and her parents were further analyzed using cloning and haplotype sequencing method. The HLA five loci linked haplotypes and the recombination site were analyzed by family study, meanwhile the full length sequences of the five HLA-C alleles were compared with the IMGT/HLA database by the program BLAST.Results The two haplotypes of the father and mother were a:A*0207-C*010201-B*550201-DRB1*090102-DRQ1*030302 and b:A*240201-C*120202-B*5201-DRB1*1502-DRQ1*0601, c:A*300101-C*060201-B*130201-DRB1*0405-DRQ1*0401 and d:A*110101-C*070201-B*4001-DRB1*080302-DRQ1*0601,respectively.The two brothers inherited their parent′s haplotypes a, d and b, c respectively.The two haplotypes of the patient were the maternal c and paternal recombinant a/b haplotype.The recombinant a/b haplotype A*240201-C*new-B*550201-DRB1*090102-DRQ1*030302, A*240201 came from the paternal haplotype b,while B*550201-DRB1*090102-DRQ1*030302 came from the other paternal haplotype a.When comparing the full length sequences of the HLA-C new allele with the father′s allele C*010201 and C*120202, it could deduce that the recombinant a/b haplotype derived from a recombination event occurring between the paternal chromosome 6 during meiosis.The crossover site was between genomic nt273 and nt330 of HLA-C alleles, which created a HLA-C new allele and the fifth haplotype of the family, and inherited it to the patient.The full length sequences of the new allele had been submitted to Genbank, and officially named C*0121 by WHO nomenclature committee.Conclusion This study demonstrates a rare inter-allelic recombination event occurring in the HLA-C locus within a Chinese Han family and illustrates the process of novel allele and haplotype, and provides direct theory for further studying the mechanisms of gene recombination and HLA polymorphism.

OBJECTIVETo observe the effect of sodium tanshinone II (A) sulfonate (STS) on Ang II -induced atrial fibroblast collagen synthesis and TGF-beta1 activation.

METHODAtrial fibroblasts of neonatal rats were cultured to determine the content of collagen protein. The original synthesis rate determined by the [3H]-proline incorporation method was taken as the index for myocardial fibrosis. The content of active TGF-beta1 and total TGF-beta1 in cell culture supernatants were tested and cultured by ELISA. The expression of thrombospondin-1 (TSP-1) was assessed by using Western blot.

RESULTAng II could significantly increase the content of atrial fibroblast collagen and the collagen synthesis rate, the TSP-1 expression and the concentration of active TGF-beta1, without any obvious change in total TGF-beta1. After the STS treatment, all of the indexes, apart from total TGF-beta1, were obviously down-regulated.

CONCLUSIONSTS could decrease the secretion of Ang II -induced atrial fibroblast collagen and the synthesis rate. Its mechanism is related to the inhibition of TSP-1/TGF-beta1 pathway.

Objective To investigate the effects of exogenous prostaglandin E 1 (PGE 1) on expression of platelet derived growth factor B (PDGF-B) mRNA and its receptor ? protein in rabbit with schistosomiasis. Methods In this study, 14 rabbits were infected with cercaria of S. japonicum percutaneously. PGE 1 ( 2.5 ?g/kg?d -1 ) was given intravenously to 7 rabbits from the 60th day to day 120. The expressions of PDGF-B mRNA, PDGFR ? protein and ?-SMA were detected by RT-PCR, Western blotting and immunohistochemistry, respectively. Endogenous IFN-? was measured by in situ hybridization. Results Up-regulated expressions of PDGF-B mRNA, receptor ? protein as well as ?-SMA were observed in rabbits with Schistosome hepatic fibrosis. The increased expressions of PDGF mRNA and receptor ? were suppressed in rabbits treated with exogenous PGE 1 (29.42?5.05 vs 41.37?7.23, P
