The morphology,cultural characteristics,physiological and biochemical properties of phosphate solubilizing strain BL-11 were studied.Combine with its 16S rDNA sequence analysis result strain BL-11 was identified as Brevibacillus laterosporus.Results showed that the phosphate solubilizing efficiency of strain BL-11was up to 10.91% when with Ca_ 3 (PO_ 3 )_ 2 as the sole phosphorus source in the medium,while the efficiency of that was up to 1.56% when with sands as the sole phosphorus source.An optimal media of BL-11 strain for solubilizing phosphate was obtained by orthogonal test.It was composed of sugar 20g/L,(NH_ 4 )_ 2 HCO_ 3 0.3g/L,MgSO_ 4 .7H_ 2 O 0.5g/L,NaCl 0.3{g/L},KCl 0.5g/L,FeSO_ 4 0.03g/L,MnSO_ 4 .H_ 2 O 0.03{g/L.}_ While other conditions were consisted of initial pH7.0-8.0,180 r/min,and 30℃.

A gene that could be potentially involved in spermatogenesis was identified and characterized by using suppression subtractive hybridization (SSH) and rapid amplification of cDNA ends (RACE) with total RNA from type A spermatogonia and pachytene spermatocytes of rat. This gene consists of 3 433 base pairs (bp) with a complete open reading frame (ORF) of 3 171 bp and encodes a putative protein containing 1057 amino acids. The nucleotide sequence displays a 93% identity to mouse ubiquitin-activating enzyme E1, Chr Y 1 (Ube1y1) and an 82% identity to human ubiquitin-activating enzyme E1 (UBE1). The putative protein of this gene contains an ubiquitin-activating enzyme signature 1 and an ubiquitin-activating enzyme active site, which are also existed in mouse ubiquitin-activating enzyme E1, human ubiquitin-activating enzyme E1 et al. So we named this gene as Rattus norvegicus ubiquitin-activating enzyme E1 (Ube1). The sequence of Ube1 was submitted to GenBank and the accession number is EF690356. Reverse transcription-polymerase chain reaction (RT-PCR) analysis showed that Ube1 was specifically expressed in testis, while its expression was not detected in heart, brain, spleen, lung, liver, muscle, kidney and ovary. Comparison of the expression of Ube1 in different developmental stages of testis and Sertoli cells (real-time PCR) indicated that Ube1 was expressed more highly in spermatogonia than in spermatocytes, spermatids and Sertoli cells. In conclusion, Ube1 is a gene encoding rat ubiquitin-activating enzyme E1 and specifically expressed in testis, which might play a key role in ubiquitin system and influence spermatogenesis.

Objective:To investigate the underlying mechanism of histone deacetylase (HDAC) inhibitor FK228-in- duced apoptosis of the prostate cancer cell line DU145.Methods:The inhibitory effect of FK228 on DU145 cell growth and its cytotoxicity were determined by MTT assay;cell cycle arrest was detected by flow cytometry assay;morphological change was observed by Giemsa staining;and defined kinase protein levels were determined by Western blot analysis.Re- suits:FK228 obviously inhibited DU145 cells growth,arrested cell cycle at G_0/G_1 phase,induced cells morphological changes and degraded several kinase proteins,including EGFR,Her2,Raf-1,Src,Cdk4 and IAP member Survivin.The degradation of these kinases blocked Raf-Mek-Erk and PI3K/Akt survival signal pathways,inducing apoptosis.Condu- sion:FK228 may induce DU145 cell apoptosis through depletion of multiple kinase proteins and blockade of survival sig- nal pathways of DU145 cells.

Objective To assess the effect of high quality nusing care on inpatients in order to expand and improve the high quality nursing care systerm.Methods Patients were investigated with questionnaire about satisfaction before and after implemented high quality nusing care.Results the score of patients' satisfaction was (47.82 ±6.919 ) and ( 50.52 ± 3.413 ),respectively,before and after implemented high quality nusing care,and the difference was statistically significant( P ＜ 0.05 ).Conclusions Implementing the “high quality nursing care” can improve the patients' satisfaction and improve the relationship between patients and nursing.

OBJECTIVETo investigate the effect of preoperative use of viable Bifidobacterium supplement on the intestinal flora, immune status, inflammatory response and prognosis of patients undergoing colorectal cancer resection.

METHODSSixty patients with colorectal cancer were randomized into treatment group (n=30) and control group (n=30). Patients in the treatment group received oral viable Bifidobacterium with routine enteral nutrition and patients in the control group received routine enteral nutrition alone. The intestinal flora of stool was analyzed and stool SIgA, serum IgG, IgM, IgA, IL-6, and C-reactive protein (CRP) were detected.

RESULTSPostoperative Bifidobacterium/E.coli (B/E) ratio in the treatment group decreased significantly as compared to the preoperative ratio (2.01+/-0.36 vs 26.53+/-4.22, P<0.05). However, the ratios remained above one. Both preoperative and postoperative B/E ratios in the control group (0.72+/-0.14, 0.02+/-0.06) were significantly lower than those in the treatment group (P<0.05). Indexes of immunity and inflammation were not significantly different between the two groups (P>0.05). At day 9 after operation, stool SIgA was higher in the treatment group, while serum IgG, IgM, IgA, IL-6, CRP in the treatment group were lower (P<0.05). Postoperative septic complications in the treatment group was less than that in the control group (P<0.05), but other complications and hospital stay were comparable.

CONCLUSIONSIn patients with colorectal cancer, supplementation of viable Bifidobacterium before surgery can improve bacterial dysbiosis and immunity, and can reconstruct the balance of intestinal flora, and reduce infection complication of surgery.

OBJECTIVETo explore the effect of acupoint massage dominant early comprehensive intervention on the prognosis of premature infants with brain injury.

METHODSTotally 210 premature infants with brain injury were assigned to the intervention group (112 cases) and the control group (98 cases). All patients received routine therapy (medicinal + routine care instructions). Patients in the intervention group additionally received acupoint massage. Those with abnormal early motion received physical sports treatment. Those with upper limbs dysfunction or with fine movement disorders received occupational therapy. Premature infants' development quotient (DQ) was performed at corrected age of 6 and 12 months by using neuropsychological development examination table for 0 - 6 years old children. The incidence of cerebral palsy was statistically calculated.

RESULTSAt corrected age of 6 months, DQ of gross motor, fine motor, language three functional areas was higher in the intervention group than in the control group with significant difference (P < 0.05). At corrected age of 12 months, DQ of gross motor, fine motor, language, social and adaptive capacities was higher in the intervention group than in the control groupwith significant difference (P < 0.05). The incidence of cerebral palsy was 4.46% (5/112) in the intervention group and 12.24% (12/98) in the control group (P < 0.05).

CONCLUSIONAcupoint massage dominant early comprehensive intervention could obviously improve the intelligence development level and lower the incidence of cerebral palsy in premature infants with brain injury.
