Objective To study the association of peptidylarginine deiminase 4 (PADI4) (padi4_94 and padi4_104) genetic single nucleotide polymorphism (SNP) and rheumatoid arthritis (RA) susceptibility in Han population of Hebei province. Methods This hospital-based case-control study included 115 RA patients and 106 healthy controls. All the individuals were recruited from Han Hebei residents and were randomly selected. The genotype and allele frequencies of PADI4 gene polymorphisms (padi4_94 and padi4_104) were analyzed by PCR-DNA sequencing method. Results The distribution of padi4_94 and padi4_104 genotypes between the two groups was not significantly deviated from that expected by Hardy-Weinberg equilibrium (P>0.05). The combined effect of padi4_94 and padi4_104 SNPs was analyzed and three haplotypos (AA, AG and GG) were found but without GA haplotype. The genotype and allele distribution of padi4_94 and padi4_104 in the patients with RA was not significantly different from that in healthy controls,and the analysis of haplotypes revealed that no haplotypes were risk factors for RA. Conclusion In Han population of Hebei province, the SNPs of PADI4 (padi4_94 or/and padi4_104) is no associated with RA susceptibility. Therefore, it should not be regarded as a genetic risk factor for RA.

Objective To investigate relationship between levels of follicle-sitimulating horomone receptor(FSHR) and ovarian response induced by gonadotropin hormone,and whether the FSHR expression is correlated with in vitro fertilization(IVF) outcome.Methods Granulose cells were collected from 43 women receiving IVF-embryo transplantation(IVF-ET).According to the number of oocyte,the women were divided into three groups: low response(15).The expression intensity of FSHR was measured by immunohistochemistry technique.The expression intensity of FSHR on the granular cell,the embryological and clinical outcomes were compared and analyzed. Results The expression of FSHR was significantly different in three groups with the highest in high response group(P0.05).The FSHR level was positively correlated either with the number of oocyte (r=0.719) or with the serum E2 levels(r=0.516,P0.05). Conclusion Ovarian response to gonadotropin hormone stimulation is correlated with the level of FSHR in the granulose cells.The development of follicles may be influenced by it.

AlM: To evaluate the clinical effect of 200g/L protein-free calf blood extract eye gel for corneal epithelial defect.METHODS: One hundred and sixty - eight cases of corneal epithelial defect ( 58 cases with herpes simplex keratitis; 24 cases with chemical injury; 85 cases with pterygium operation injury ) were randomly divided into two groups: 84 eyes were treated with protein-free calf blood extract eye gel; 84 cases were treated with basic fibroblast growth factor eye gel ( bFGF ) . The bFGF and protein-free calf blood extract eye gels were used 4 times a day. The treatment course was 7d. Epithelial defect restoration, local symptom and sign were observed.
RESULTS: The difference between pre-treatment and post-treatment was significant ( P<0. 01 ) in the two groups. The effect of protein-free calf blood extract eye gel (83. 3%) group was prior to that of bFGF (69%) for corneal epithelial defect. The effective rate of protein-free calf blood extract eye gel in the herpes simplex keratitis, chemical injury and pterygium operation injury was 72. 4%,69. 2% and 95. 2%. Localized stimulus and adverse reaction of all over the body were not been observed.
CONCLUSlON: Protein-free calf blood extract eye gels is valuable and safe for corneal epithelial defect.

Objective To study the gene polymorphism at position padi4_94 in Chinese Han people of Hebei Province and the characters of distribution.Methods 106 healthy individuals and 115 rheumatoid arthritis patients in Hebei Province were randomly selected. Padi4_94 gene was screened by sequencing of the promotor. The correlations between the SNP site and anti-cyclic citrullinated peptide antibody (anti-CCP) was discussed.Results There were three genotypes: AA, AG and GG in Chinese Han people of Hebei Province. No significant differences of gene frequency and allele gene frequency were found between healthy individuals and RA patients, and no correlation between SNP and the production of anti-CCP.Conclusions Hebei Province The gene polymorphisms at position padi4_94 existed in Chinese Han people of Hebei Province,but possibly would not affect RA susceptibility and the production of anti-CCP.

Objective To evaluate the role of early cleavage embryo in combination with embryo growth rate and morphology scoring in embryo selection in in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles. Methods Six hundred and ten IVF/ICSI cycles were randomly assigned to group A(269 cycles) and group B(341 cycles). In group A, transferred embryos were chosen according to embryo growth rate and morphology scoring by 72 h(D3) after fertilization, while early cleavage embryo was added to the selecting system in group B. The pregnancy rate and implantation rate were compared between two groups, and the clinic outcomes were compared between transfers with early cleavage embryos and without early cleavage embryos in group B. Results The pregnancy rate and implantation rate in group B were significantly higher than those in group A (P < 0.05). Transfers with early cleavage embryos also achieved much higher pregnancy rate and implantation rate in group B (P < 0.01). Conclusion Compared with embryo growth rate and morphology scoring, early cleavage embryo in combination with embryo growth rate and morphology scoring can improve the clinical outcomes in IVF/ICSI cycles.

AIM: To understand the relation between the penetrating keratoplasty rejection and the methods of cornea preservation.
METHODS: The 30 Wistar rats as donator and 60 SD rats as receptor were used to establish the animal models of penetrating keratoplasty rejection. And 60 SD rats were randomly divided into 3 groups. Donor cornea of Wistar rats preserved in different methods were used separately in 3 groups. The penetrating keratoplasty rejection index ( RI ) , means survival time ( MST ) of corneal grafts and pathological changes in post -operation were analyzed.
RESULTS: The MST was ( 10. 4±1. 70 ) d in moist-chamber- preserved group (Ⅰ), ( 12. 9 ± 1. 81 ) d in medium-term-preserved group (II) and (16. 1±2. 57) d in cryopreserved group ( Ⅲ) . The MST in the cryopreserved group was evidently prolonged, showing a significant correlation compared with other two groups (P<0. 01). The sections with HE staining revealed that the severity of inflammation in Ⅲ group was reduced compared with that of Ⅰ, II group after 10d of keratoplasty.
CONCLUSION: The postoperative rejection of penetrating keratoplasty in rats is decreased and rejection time is delayed in cryopreserved cornea.

Objective To study the relationship between reactive oxygen species (ROS) as well as total antioxidant capacity ( TAC ) within follicle fluid and body mass index ( BMI ) in patients with polycystic ovary syndrome (PCOS).Methods All patients enrolled in this study were infertile women receiving in vitro fertilization-embryo transfer (IVF-ET) treatment.55 PCOS patients were divided into over-weight group ( n =23 ) and non-over-weight group ( n =32 ).Another 55 age-matched non-PCOS women were also divided into control group ( n =30) and overweight group ( n =25 ).Plasma sex hormone,triglycerides,and total cholesterol were determined.On oocyte retrieval day after ovarian stimulation,ROS and TAC in follicular fluid were assayed.Results Subjects in over-weight and PCOS over-weight groups had higher triglycerides than those in control and PCOS non-over-weight groups [ ( 1.9 ±1.1,1.7 ± 0.9,1.0 ± 0.5,1.2 ± 0.7 ) mmol/L,respectively,all P＜0.05],so did total cholesterol [ ( 4.8 ± 1.2,5.2 ± 1.1,4.0 ± 0.6) mmol/L,respectively,all P＜0.05].In PCOS over-weight group,ROS and ROS/TAC within follicular fluid were ( 35.4 ± 6.7 ) RLU/S and 39.8 ± 22.0,both were higher than those in the other 3 groups ( all P＜0.05).TAC [ (0.8 ± 0.5 ) Mm] was lower in PCOS over-weight group than that among the other 3 groups( all P＜0.05 ).ROS/TAC was higher in PCOS non-over-weight group than that of control group ( 26.5 ± 14.5 vs 14.2 ± 12.5,P＜0.05 ).Univariate analysis showed that both ROS and ROS/TAC within follicular fluid in PCOS patients were positively correlated with BMI ( r =0.34 and r =0.32,both P＜0.05 ).Conclusion Abnormal oxidative stress exists in follicular fluid of PCOS patients,and the oxidative stress parameters show positive correlation with BMI.
