In order to determine the challenge dose of pigeon paramyxovirus type 1 (PPMV-1) inactivated vaccine (S-1 strain). The virus titer of PPMV-1 E5 allantoic fluid (Chuansha strain) was determined using SPF chicken embryos in this research. After inoculating 30-day-old and 120-day-old pigeons with low-HI antibody against PPMV-1 (HI antibody < or =2) with different doses of PPMV-1 (Chuansha strain), the clinical symptoms and histopathological lesions of the challenged pigeons were examined. The results showed that the minimal lethal dose (MLD) of PPMV-1 (Chuansha strain) was 102.5 ELD50, so we determined that 10(5.5) ELD50, which was 1000 times the MLD, could be taken as the challenge dose in the vaccine efficacy test for PPMV-1 inactivated vaccine (S-1 strain).

Focused Ultrasound Surgery (FUS) is a promising minimally invasive technique in tissue ablation. Because of the high intensity at the ultrasound focus, a precise 3D-localization system is required to determine the site of the treating target in order to increase the efficiency and security of FUS. This paper represents a three dimensional ultrasound (3D US) localization system developed and its workflow. The system is mainly composed of imaging and image processing system, movement device and its controlling circuits, and position feedback device. The system has a maximum scan range of +/- 30 degrees with a resolution of 8 levels from 0.54' to 0.36 degrees. For a spherical shape like target, in theory, the maximum diameter is 160 mm the system can treat. The system can be used to localize precisely the treatment targets with general sizes in the suitable parts of the body in FUS.

BACKGROUND:Studies have shown that vacuum sealing drainage can accelerate wound healing through increasing the wound blood flow, but its influence on activated gelatinases in human chronic wound stil lacks corresponding research. OBJECTIVE:To observe the effect of vacuum sealing drainage on the activity of gelatinase during the healing of chronic wounds. METHODS:Total y 96 trauma patients admitted at the People’s Hospital of Hubei University of Medicine from April 2013 to January 2014 were divided into two groups:52 patients in chronic wound group were treated with vacuum sealing drainage and 44 in control group treated with wound drainage at 3 days after removal of breast cancer. In the chronic wound group, exudates from pressure sores and skin necrosis after removal of breast cancer were col ected as samples A and B;exudates from two cases of venous stasis ulcer were col ected as samples C and D;exudates from traumatic skin wounds col ected as sample E. RESULTS AND CONCLUSION:TLC analyzer showed that:after 15-day negative pressure therapy, activities of matrix metal oproteinase 2 in sample A with low activity of gelatinase, matrix metal oproteinase 9 in sample B, matrix metal oproteinase 2 and 9 in samples C, D, E were al increased significantly (P<0.05);however, the activities of matrix metal oproteinase 9 in sample A with high activity of gelatinases and matrix metal oproteinase 2 in sample B were reduced significantly after treatment (P<0.05). In addition, no significant difference was found in the activity of matrix metal oproteinase 2, matrix metal oproteinase 9 and activated gelatinase betweenthe chronic wound group and control group (P>0.05). These findings indicate that the variation of activated gelatinases activity in human chronic wounds may be the reason why the chronic wounds cannot be healed for a long time, but vacuum sealing drainage can regulate the activity of activated gelatinases in chronic wounds.

Objective To study the protective effect and its mechanism of anti-tumor necrosis factor-?antibody (TNF-? Ab) on lung injury after cardiopulmanary bypass(CPB).Methods Twenty-eight healthy rabbits were selected and randomly divided into four groups:group Ⅰ only received open chest operation;groups Ⅱ-Ⅳ underwent CPB.In the group Ⅳ,rabbit TNF-? Ab (2 400 pg/kg) was dropped into the intracheal tube before operation and just after releasing the aortic clamp.Saline was given to the group Ⅲ in- stead.Blood neutrophils count,TNF-?,MDA from the right and left atrium in the four groups were determined perioperatively.Water volume,TNF-? mRNA,TNF-? protein,apoptosis and pathomorphological changes were measured in the lung tissues.Results TNF- ? Ab can restrain leukocyte accumulation,reduce releasing of TNF-? and MDA in the lung.It can also reduce the occurrence of apop- tosis and attenuate pathomorphological changes in the lung tissue.However,it cannot reduce the secretion of TNF-? at the transcrip- tion level and protein level.Conclusion Intratracheal TNF-? Ab administration has markedly protective effect on lung injury after CPB.

OBJECTIVETo study the effect of solid dispersion technology and inclusion technology on dissolution performance of Pulsatillae total saponins, and preliminarily investigate its mechanism.

METHODThe solid dispersion of Pulsatillae total saponins-PEG 4000 was prepared by the melting method. The inclusion compound of Pulsatillae total saponins-hydroxypropyl-beta-cyclodextrin ( HP-beta-CD) was prepared by the freeze-drying method. The properties of solid dispersion and inclusion compound were identified by using IR, DSC and NMR. And the dissolution of solid dispersion and inclusion compound were also determined by the small glass method.

RESULTIR, DSC and NMR results showed the formation of solid dispersion and inclusion compound. In terms of the dissolution, the inclusion compound ranked first, which was followed by solid dispersion and bulk pharmaceutical chemicals.

CONCLUSIONThe inclusion technology could significantly increase the dissolution of Pulsatillae total saponins, whereas the solid dispersion showed no notable solubilization effect.

OBJECTIVETo investigate the protective effect of Danxuetong injection (DXT, a combination of Danshen and Xueshuantong injections) against testicular ischemia-reperfusion injury following testis torsion/detorsion in rats.

METHODSThirty-two 4-week-old healthy male SD rats were randomly divided into four groups of equal number: sham operation, normal saline, single DXT injection, and successive DXT injection. The rat models of testicular ischemia-reperfusion injury were established by 2-hour 720-degree torsion/detorsion of the unilateral testis. At 6 weeks after modeling, the rats were killed and their testes were harvested for measure- ment of testicular coefficients, sperm counts, sperm motility, and the levels of total anti-oxidative capacity (T-AOC) , superoxide dismutase (SOD) , nitric oxide synthase (NOS) , and malondialdehyde ( MDA) in the testis tissue.

RESULTSCompared with the rats of the normal saline group, those of the single DXT injection and successive DXT injection groups showed significant increases in the testicular coefficient (0.11 ± 0.03 vs 0.35 ± 0.04 and 0.40 ± 0.06, P < 0.05), sperm count ([0.46 ± 0.10] vs [1.44 ± 0.50] and [3.00 ± 1.28] x10(9)/ml, P < 0.05), sperm motility ([13.63 ± 14.04] vs [39.63 ± 5.04] and [76.31 ± 3.67]%, P < 0.05), the activity of SOD (72.76 ± 5.58 vs 116.25 ± 8.83 and 133.20 ± 13.84, P < 0.05), and the level of T-AOC (5.58 ± 1.07 vs 13.34 ± 5.81 and 19.21 ± 5.69, P < 0.05), but a remarkable decrease in the content of MDA (42.38 ± 8.94 vs 20.94 ± 5.65 and 15.02 ± 1.03, P < 0. 05) in the injured testes.

CONCLUSIONDXT can effectively rid the testis tissue of oxygen free radicals, improve sperm count and motility by antioxidation, and protect the testis tissue of prepubertal rats against testicular ischemia-reperfusion injury after testis torsion/detorsion. It also has a protective effect on the contralateral testis, and successive injection has a better effect than single injection of DXT.

OBJECTIVETo assess the association of the A260G and A386G single nucleotide polymorphisms (SNP) of the DAZL gene with male infertility in the Chinese population of Zhejiang Province.

METHODSWe collected the peripheral blood samples from 317 idiopathic infertile males with azoospermia or oligozoospermia and 246 normal fertile men, and genotyped the polymorphic loci of the A260G and A386G polymorphisms of the DAZL gene using the SNaPshot technique.

RESULTSThe DAZL gene A260G was found genetically polymorphic in the Chinese population of Zhejiang Province, with the gene frequencies and their distribution consistent to the Hardy-Weinberg equilibrium. The frequencies of the AA, AG and GG genotypes of the A260G polymorphism were 92.3%, 7.3%, and 0.4% respectively in the normal controls and 94.3%, 5.7%, and 0% in the infertile patients, with no statistically significant differences between the two groups (P = 0.43, OR = 0.78, 95% CI 0.413-1.46). Heterozygosis (AG) of A386G was found in 1 of the control males but not in the infertile patients, while homozygosis (GG) of A386G was not observed in either group (P = 0.259, OR = 0.698, 59% CI: 0.374-1.306).

CONCLUSIONA260G and A386G SNPs of the DAZL gene are not associated with spermatogenic failure and neither represents a molecular marker for the genetic diagnosis of male infertility in the Chinese population of Zhejiang Province.

Objective: To observe the joint effect of school and family tobacco control on middle school students, and to explore its effectiveness in reducing second-hand smoke exposure in middle school students’ families, as so asto provide a new way of thinking for controlling smoking among middle school sudents. Methods: A questionnaire survey was conducted on the study of 2 125 primary and high school students in four middle schools in the Dongcheng District of Beijing by means of a stratified group sampling method. Personal information of students, tobacco control environment around the family, school and surrounding ares, as well as the knowledge, attitude and behavior of students related to tobacco control was collected. Results: The exposure rate of second-hand smoke in the families of middle and high school students in Dongcheng District of Beijing was 33.41%. Smoking by at least one parent was positively correlated with second-hand smoke exposure in the student’s home (OR=22.88, P<0.05). Among the students who saw the "clear no-smoking label" on campus, the exposure rate (4.92%) when the smoking restriction was set on the home was lower than that of those who did not have a regulation in the home (58.94%) (χ2=452.57, P<0.01). The results of Logistic regression showed that there was a combination of family smoking restrictions and second-hand smoke exposure in middle and high school students who had seen the smoking ban on campus (OR=0.08) and had the school’s tobacco control education (OR=0.08). Conclusion The joint tobacco control measures between school and family can effectively reduce the exposure rate of second-hand smoke in middle school students’ families, which is better than the effect of tobacco control alone.
