Objective To study the relationship among insulin-like growth factor 1 (IGF-1), insulin-like growth factor binding protein 3(IGFBP-3) and birth weight, length and placental weight and to discuss the endocrine factors which affected fetal growth by assaying levels of IGF-1、IGFBP-3 in umbilical cord serum.Methods The neonates were divided into appropriate for gestational age infant(AGA) and small for gestational age infant(SGA) according to birth weight and gestation. The birth weight, length and placental weight of neonates were measured and at meantime the levels of IGF-1 and IGFBP-3 were assayed by immunoradiometric assay.Results 1.There were 105 neonates, including 79 AGA and 26 SGA. There were significantly statistical differences in birth weight, length and placental weight (all, P

According to the designed specific primers of gene fragment based on the Salvia miltiorrhiza transcriptome data, a full-length cDNA sequence of SQS2 from S. miltiorrhiza f. alba was cloned by the method of reverse transcription polymerase chain reaction (RT-PCR). The SmSQS2 cDNA sequence was obtained, this sequence is named SmSQS2 and its GenBank registration number is KM244731. The full length of SmSQS2 cDNA was 1245 bp, encoding 414 amino acids including 5'UTR 115 bp and 3'UTR 237 bp. Sequence alignment and phylogenetic analysis demonstrated that SmSQS2 had relative close relationship to the SQS2 of S. miltiorrhiza. The induction of E. coli [pET28-SQS2] in different temperature, induction time, IPTG concentrations and density of inducing host bacterium (A600) were performed, Shaking the culture at 30 degrees C until the A600 is approximately 0.6 and add IPTG to final concentration of 0.2 mmol x L(-1), and then the optimal expression of SmSQS2 recombinant protein were accumulated after the induction time of 20 h. The research provided important base for the study of sterol and terpene biosynthesis of SQS2 in S. miltiorrhiza f. alba.

? AIM: To investigate health - related quality of life ( HRQOL ) state in children with intermittent exotropia using the Intermittent Exotropia Questionnaire ( IXTQ ) and research the effect of strabismus surgeries on HRQOL.?METHODS: In this prospective study, we chose 42 patients with intermittent exotropia ( aged 5-17 years) as case group, and 42 patients ( aged 5-17 years) as control group. The Chinese IXTQ was used to evaluate HRQOL at 1d preoperatively and 3mo postoperatively in the two groups, and the differences of the two groups before and after surgery and the effect of strabismus surgery on HRQOL were analyzed.?RESULTS:The scores of HRQOL in control group were statistically significant higher than that of case group ( P<0. 01 ). Every items showed a statistically significant difference except on “Kids tease me because of my eyes”and “ My eyes make it hard for me to make friends” ( P<0.05). At 3mo postoperatively ,the scores of HRQOL in case group significantly increased than that at 1d preoperatively(P<0. 01). Child IXTQ of case group was lower on every items than those of control group after surgery(P<0. 05).?CONCLUSION:Intermittent exotropia could affect the HRQOL in psychosocial and visual functional. The greatest HRQOL concerns for children with intermittent exotropia were shutting one eye when sunny, waiting for their eyes to clear up instead of taunts and friendship. The surgical treatment could improve HRQOL in children with intermittent exotropia.

Acyl carrier protein is an essential component involved in the biosynthesis of DHA(Docosahexaenoic Acid) via PKS(Polyketide synthase) pathway,which takes the growing acyl chain from one enzyme to another.One cDNA clone,with high homology of ACP,was isolated from Schizochytrium sp.FJU-512 cDNA library.The deduced amino acid sequence contained 142 residues with isoelectric point of 5.04 and had the 4'-phosphopantetheine prosthetic(4'-PP) binding site.The target fragment was digested with BamHⅠ/HindⅢand inserted into the expression vector pET-30a resulting in the plasmid pET-30a/acp.The recombinant vector was transformed into E.coli BL21(DE3) and induced by IPTG.SDS-PAGE analysis demonstrated that ACP was effectively expressed.

Objective To study the changes of serum level of high mobility group box-1(HMGB- 1)in patients with multiple trauma in order to forecast organ dysfunction(OD)and deaths.Methods The optical densities of HMGB-1 in serum of 35 patients with multiple trauma were determined on 1st,3rd, and 7th days after trauma,and the incidence of organ dysfunction and deaths were evaluated,then analyzed statistically to learn the relation between the serum levels of HMGB-1 and deaths with an attempt of predic- ting the incident of organ dysfunction and deaths.Results (1)As OD was concerned,there was a statis- tically significant difference in optical density of HMGB-1 on 1st and 3rd days between the two groups of multiple injury patients(t=4.411,P

20(Z= -2.117, P=0.034), and between the patients with OD and without OD (Z=-3.089, P=0.002), but PCT was not so between the non-surviror and survivor (Z=-1.307, P=0.191). The serum PCT level correlated with the incidence of organ dysfunction (x~2=14.82, P=0.033) and APACHEII (x~2=12.83, P

Objective To detect the levels of cytokine IL-2,IL-12,IFN-?and IL-4 secreted by peripheral CD8~+ T lymphocytes in patients with condyloma acuminatum (CA).Methods Flow cytometry was employed to study the expression of cytokines IL-2,-12,INF-?and IL-4 in CD8~+ T lymphocytes in the peripheral blood of 60 patients with CA and 20 healthy controls.Results The percentage of CD8~+ T lym- phocytes producing IL-2,IL-12 and IFN-?were significantly lower in CA patients than that in healthy con- trols (P

The latest findings of our laboratory showed that Angelica sinensis polysaccharide (ASP) showed a definite effect in regulating the aging of hematopoietic stem cells. Leukemia is a type of malignant hematopoietic tumor in hematopoietic stem cells. There have been no relevant reports about ASP's effect in regulating the aging of leukemia cells. In this study, human acute myeloid leukemia (AML) KG1alpha cell lines in logarithmic growth phase were taken as the study object, and were divided into the ASP group, the cytarabine (Ara-C) group, the ASP + Ara-C group and the control group. The groups were respectively treated with different concentration of ASP, Ara-C and ASP + Ara-C for different periods, with the aim to study the effect of ASP combined with Ara-C in regulating the aging of human acute myeloid leukemia KG1alpha cell lines and its relevant mechanism. The results showed that ASP, Ara-C and ASP + Ara-C could obviously inhibit KG1alpha cell proliferation in vitro, block the cells in G0/G1 phase. The cells showed the aging morphological feature. The percentage of positive stained aging cells was dramatically increased, and could significantly up-regulate the expression of aging-related proteins P16 and RB, which were more obvious in the ASP + Ara-C group. In conclusion, the aging mechanism of KG1alpha cell induced by ASP and Ara-C may be related to the regulation of the expression of aging-related proteins, suggesting that the combined administration of ASP and anticancer drugs plays a better role in the treatment of leukemia .
