AIM: To screen TIGR/myocilin gene (MYOC) mutation in high myopic Chinese children with family history.METHODS: Gene sequencing was performed in exon 3 of the TIGR gene in high myopic Chinese Children. The coding sequence of TIGR exon 3 was screened by capillary electrophoresis sequencing. The sequence alterations were analyzed by bioinformatics.RESULTS: TIGR gene mutation was not found in high myopic patients and normal controls group.CONCLUSION: No identified gene mutation is found in TIGR gene in high myopic Chinese children.

To review the background and advance of a strategy of bioethnopharmaceutical analytical pharmacology(BAP).BAP is an idea for elucidating absorbed bioactive compound(ABC)in traditional Chinese medicine(TCM)formula or herbal remedy.It is also a mode of active comparison between absorbed compounds and the parent formula including determination of ABC in blood,the ABC dosage identical to its content in formula,and the active comparison of ABC and the parent formula.The ABC of Guan-Xin-Er-Hao formula elucidated by BAP strategy has been reviewed and the significance of BAP strategy will be further discussed.

Objective To explore the change of activin A(ACT A) in umbilical artery blood of newborns with fetal distress and its clinical significance.Methods Forty healthy pregnant women(control group)and 35 pregnant women with fetal distress (experimental group)were collected.The levels of ACT A of umbilical artery blood in both groups were determined by a solid quantitative biotin-avidin system enzyme-linked immunosorbent assay(BAS-ELISA),umbilical artery blood gas were also measured.Results The level of ACT A of umbilical artery blood in fetal distress group was (1 235.89?178.78)ng/L,and that in control group was (627.28?75.24)ng/L,and the level of ACT A of umbilical artery blood in fetal distress group was significantly higher than that in control group(P

OBJECTIVETo clone and screen genes related to multidrug resistance (MDR) in leukemia.
METHODSSuppression subtractive hybridization (SSH) was performed to profile differentially expressed genes between a MDR leukemia cell line (K562/DOX, as tester) and its parent cell line (K562, as driver). Reverse Northern dot blot was carried out to further screen the subtracted cDNA library. The overexpressed cDNA fragments in K562/DOX cells were sequenced and compared with known genes in Genbank. RT-PCR and Northern blot were employed to confirm the differential expression of some identified genes.
RESULTSEleven genes were identified being overexpressed in K562/DOX, including S3 ribosomal protein (S3rp) gene, NADH dehydrogenase subunit 2 (ND2) gene and My023 gene, which have not been reported to be related to MDR in cancer.
CONCLUSIONSeveral genes, which might be involved in MDR were identified, indicating novel mechanisms of MDR in leukemia.

Background Statistic data revealed that different retinopathy of pre-term infants have different susceptibility to retinopathy of prematurity (ROP),which may be associated with polymorphism of vascular endothelial growth factor(VEGF) gene.Objective This study was to determine the association of polymorphisms of VEGF gene with the risk for ROP.Methods This research was approved by Ethics Committee of Hunan Children's Hospital,and written informed consent was obtained from the parents of patients.A prospective case-controlled study was designed.Ninety-nine ROP patients in Hunan Children' s Hospital and 88 pre-termed children without ROP were included from January,2006 to December,2009.Thirty-nine patients who received retinal photocoagulation or cryotherapy were included as the treatment group,and 60 untreated but spontaneously regressed ROP patients as the non-treatment group.No significant differences were seen in demography between with the ROP group and the without ROP group,or between the treatment group and the non-treatment group (all P>0.05).2 mL of peripheral blood was collected for the extraction of DNA.Gene polymorphisms of VEGF-A+405 and VEGF-A936 were detected using the pyrosequencing method.Results No significant difference was found in the frequencies of the VEGF-A+405 gene polymorphisms between the ROP group and without ROP group (P =0.071,OR =0.675,95 % CI =0.444-1.026).Also no significant difference was found in the frequencies of the VEGF-A936 gene polymorphisms between with the ROP group and without the ROP group (P =0.118,OR =0.768,95 % CI=2.823-4.614).However,the frequencies of the VEGF-A+405 gene polymorphisms were significantly higher in the ROP treatment group than the non-treatment group (P<0.01,OR--0.857,95 % CI =5.239-14.024),and VEGF-A936 gene polymorphisms was also significantly higher in the ROP treatment group than the non-treatment group (P =0.000,OR =3.609,95 % CI =0.711-0.829).Conclusions There is no association between the VEGF-A+405/VEGF-A936 single nucleotide polymorphism with the risk of ROP,but polymorphisms of VEGF gene may be correlated with the prognosis of ROP.The carrier of VEGF-A +405 /VEGF-A936 allele is more susceptible to ROP progression.

OBJECTIVETo investigate the incidence of hepatotoxicity in acquired immunodeficiency syndrome (AIDS) patients on combined anti-retroviral therapy (cART) containing nevirapine (NVP) and to assess the risk factors and its impact on cART.
METHODS330 AIDS patients from March 2003 to June 2008 at local county were enrolled and a retrospective study using Kaplan-meier survival and Multivariate logistic regression modeling was conducted.
RESULTS267 out of 330 patients received NVP based cART and 63 cases received EFV-based cART. The deference of prevalences of hepatotoxicity between the two groups is statistically significant (Chi2 = 6.691, P = 0.01). 133 out of 267 (49.8%) patients on NVP based cART had at least one episode of ALT elevation during a median 21 months (interquartile ranges, IQR 6, 37) follow-up time, amounts for 28.5 cases per 100 person-years. Baseline ALT elevation (OR = 14.368, P = 0.017)and HCV co-infection (OR = 3.009, P = 0.000) were risk factors for cART related hepatotoxicity, while greatly increased CD4+ T(CD4) cell count was protective against hepatotoxicity development (OR = 0.996, P = 0.000). Patients co-infected with HCV received NVP-based cART had the higher probability of hepatotoxicity than those without HCV co-infection (Log rank: Chi2 = 16.764, P = 0.000). 23 out of the 133 subjects (17.3%) with NVP related hepatotoxicity discontinued cART temporarily or shifted NVP to efavirenz.
CONCLUSIONNVP related hepatotoxicity was common among ARV naive HIV infected subjects in our cohort. Baseline ALT elevation and HCV co-infection were associated statistically with the development of hepatotoxicity. Hepatotoxicity led to discontinuing cART temporarily or switching to other regimens in some subjects. It suggested that NVP should be used with caution in patients co-infected with HCV among whom anti-HCV therapy before cART initiation may contribute to minimizing the probability of NVP associated hepatotoxicity.
