A strain Trichoderma koningii No.0143 which produces cellulase was isolated from 11 fungi in the east area in QingHai,its FPA activity was 15u/g. It can be used in enzymatic feed.

AIM: To investigate the levels of IL-18, IL-16, IL-8, eotaxin and the chymase activity in the sputum of asthmatics. METHODS: IL-18, IL-16, IL-8 and eotaxin levels were detected with sandwich ELISA procedures and chymase activity was determined spectrophotometrically (410 nm) by the rate of hydrolysis of N-succinyl-L-Ala-L-Ala-L-Pro-L-Phe-p-nitroanilide (SAAPP). RESULTS: The specific chymase activities in the severe and moderate asthmatics were higher than that in controls. Native protease inhibitors ?_1-antitrypsin (?_1-AT) and soybean trypsin inhibitor (SBTI) inhibited 71.9% and 72.1% enzymatic chymase activity, respectively. The levels of IL-18, IL-16, IL-8 and eotaxin were significantly elevated in the sputum of patients with acute asthma. There were correlations between the levels of IL-8 and IL-16 (r=0.55, P

Objective To map the deletion breakpoint of chromosome 9p21 in breast cancer cell line MCF-7. Methods The deletion of chromosome 9p21 was checked by Multiplex Ligation-dependent Probe Amplification (MLPA) in MCF-7. Subsequently, the deletion breakpoint was amplified by long range PCR and the deletion region was narrowed by primer walking. Finally, the deletion position was confirmed by sequencing. Results The deletion was found starting within the MTAP gene and ending within CDKN2A gene by MLPA. Based on long range PCR and primer walking, the deletion was confirmed to cover the region from chr9:21819532 to chr9:21989622 by sequencing, with a deletion size of 170kb, starting within the intron 4 of MTAP and ending within the intron 1 near exon 1β of CDKN2A. Conclusions Long range PCR is an efficient way to detect deletion breakpoints. In MCF-7, the deletion has been confirmed to be 170kb, starting within the MTAP gene and ending within the CDKN2A gene. The significance of the deletion warrants further research.

AlM: To explore the different ages of congenital nasolacrimal duct obstruction in infants, take different treatment methods at different times.
METHODS:The 87 cases of 102 children were divided into three different age groups: the first group of 25d-3mo of age 21 cases 26 eyes; The second group >3mo-7mo 31 cases 36 eyes;The third group >7-24mo of age 35 cases 40 eyes. For the first group of infants, the implementation of the lacrimal sac nasolacrimal duct massage + eye drops; for the second group of infants, carry lacrimal pressure washing treatment; for the third group of infants, the implementation of the nasolacrimal duct probing treatment.
RESULTS: The first group of children through the nasolacrimal duct sac massage + drops tobramycin eye drops treatment unobstructed 12, the cure rate was 46. 2%;The second group of children through pressurized irrigation treatment lacrimal patency by 33, the cure rate was 91. 7%; The third group of children through the nasolacrimal duct probing unobstructed 36 treatment, the cure rate was 90. 0%. The second and third group were better than the first group (χ2=15. 71, P<0. 01;χ2=15. 27, P<0. 01);the treatment effect of the second and third groups was no significant difference (χ2=0. 02, P>0. 05).
CONCLUSlON:lnfants with congenital nasolacrimal duct obstruction should distinguish between ages, taking different treatments, in order to obtain a better therapeutic effect, and lacrimal pressure washing is the preferred way of treating infants with congenital nasolacrimal duct obstruction.

Usage of reverse genetic techniques in the research area of the fundamental etiology of foot-and-mouth disease virus (FMDV), has resolved the issue about the function of viral gene of FMDV on genomic integer level. At present, a further recognition and apprehension for the molecular etiology of FMDV based on the development in reverse genetics was made. Combined with the research work in our labs, we reviewed international advances about the molecular pathogenic mechanism, the relationship be-tween virulence and variation in the genomes, influencing factors for the viral replication, and the develop-ment of new-type gene vaccine of FMD in this article, and propose the potential research aspects in reverse genetics of FMDV in the future.

Objective To survey the prevalence of elderly asthmatics among urban and rural residents of Liaoning Province and to provide data for preventive and therapeutic policies of asthma. Methods Stratified cluster disproportional 2.5‰ random sampling survey for 116 276 re sidents was performed using uniform scheme, procedures and questionnaire. Among them 12 735 cases were over 60 years old. Results Totally 522 cases (207 male and 315 female) were diagnosed as asthma, the overa ll prevalence was 1 25% and that of elderly was 4 09% ( male 3 26%, female 4 92%, P

Objective To investigate the potential relationship between initial 131Ⅰ uptake by lung metastases from differentiated thyroid cancer (DTC) and treatment outcomes. Methods From 1997 to 2009, 41 patients with DTC lung metastases were treated in the authors' department. 131Ⅰ whole body scan (WBS), serum Tg levels and other imaging results were analyzed to evaluate the therapeutic effects. Complete response (CR) or partial response (PR) was considered to be effective. The x2 test and correlation analysis were performed using SPSS 11.5 software package. Results 131 Ⅰ treatment was effective in 63% (26/41) patients with DTC lung metastases, CR in 8 patients and PR in 18 patients. In other 37% ( 15/41 ) patients, 131Ⅰ treatment was ineffective, including one case died of distant metastases. Patients with initial presence of 131Ⅰ lung uptake had higher effective rate than those with 131Ⅰ lung uptake during the second or later 131Ⅰ treatment (76% (22/29)vs33% (4/12),x2 =4.911, P=0.027). Also, significantly higher effective rate was found in patients with lung metastases alone than those with extra-pulmonary metastases (75% (24/32) vs 22% (2/9), x2 = 6. 312, P =0.012). However, the effective rate in patients with diffuse metastases was not significantly different from that in patients with focal metastases (67% (12/18)vs 61% ( 14/23), x2 =0. 146, P=0.702). The positive rate of initial 131Ⅰ uptake by lung metastases was higher in patients with total thyroidectomy than those with partial thyroidectomy (83% (24/29) vs 42% (5/12) ). Those positive rates in patients with papilary DTC and patients with follicular DTC were 72% (23/32) and 6/9, respectively. The surgical mode was correlated with the initial 131Ⅰ uptake by lung metastases (r = 0.411, P ＜ 0.05), but no correlation was found between the histological type and the initial 131Ⅰ uptake by lung metastases ( r = 0. 047, P ＞ 0.05 ). Conclusion Initial uptake of 131 Ⅰ by lung metastases alone is a favorable prognostic factor for DTC patients treated by131Ⅰ, and total thyroidectomy may be beneficial for initial 131Ⅰ uptake by lung metastases.
