Objective To explore the association of Gly71Arg mutation in gene of bilirubin uridine 5'-diphosphate-glucuronosyltransferase(UGT1A1)and neonatal jaundice in Beijing city Han population.Methods The genotypes and alleles of the Gly71 Arg polymorphism for UGT1A1 gene were identified by polymerase chain reaction-restricted fragment length polymorphism assay in infants of Beijing city Han population of China,including 96 infants with neonatal jaundice[serum bilirubin(307.06?38.5)?mol/L,indirect bilirubin(292.9?35.9)?mol/L] and 101 healthy control infants [serum bilirubin(131.2?42.1)?mol/L,indirect bilirubin(126.3?39.7)?mol/L].The genotypes and allele frequencies of the polymorphism were compared between infants with neonatal jaundice group and healthy infant group(control group).The effect of polymorphism in infants with neonatal jaundice group on serum bilirubin level were analyzed.Results There were significant differences in genotypes distribution in Gly71Arg polymorphism for UGT1A1 gene between the 2 groups(?2=9.47 P=0.002).Compared with control group,neonatal jaundice group had significantly higher Arg allele frequency in the polymorphism for UGT1A1 gene(?2=10.34 P=0.001).There were independent effects of Gly71Arg mutation in the gene on serum bilirubin level in neonatal jaundice group,at the carriers of homozygote of the Arg allele of Gly71Arg polymorphism had higher serum bilirubin levels compared to carriers of heterozygote of the Arg allele of the polymorphism and non-carriers of the Arg allele of the polymorphism(Pa

OBJECTIVETo explore the effect of a self-made guiding needle of steel wire in guiding the wire through the tibial tunnel for the treatment of avulsion fractures of tibial posterior cruciate ligament with open reduction and wire fixation.

METHODSFrom February 2011 to June 2014, a total of 22 patients with avulsion fractures of tibial posterior cruciate ligament underwent surgical treatments were analyzed, including 14 males and 8 females with an average age of 35.6 years old (ranged, 17 to 63 years old). According to Meyers classification, 9 patients were classified as type II, 13 patients were classified as type III. All the patients underwent open reduction and wire fixation with medial knee "L" shape approach. A wire guiding needle was used to guide the wire through the tibial tunnel during operation.

RESULTSWith the assistance of wire guidance needles, wires passed through the tibial tunnel rapidly during the operation in all the 22 patients. All the patients were followed up, X-ray imagings 6 months after operation showed the fractures healed well. The average follow-up time in all patients was 6 months (ranged, 6 to 12 months). The averaged Lysholm knee score in 22 knee was 92.7 +/- 3.4. All patients' posterior drawer test were negative.

CONCLUSIONSelf-made wire guiding needle can simplify the operation procedures in which the wires pass through the tibial tunnel, shorten the operation time, reduce the surgical trauma and complications, and be worthy of clinical application.

AIM: To explore the predisposing factors, population characteristics and clinical features of severe fungal keratitis.
METHODS:The data of 233 cases 233 eyes of severe fungal keratitis in my hospital from January, 2008 to November, 2013 was retrospectively reviewed. The predisposing factors, population characteristics and clinical features were analyzed.
RESULTS: In 233 cases of severe fungal keratitis, the number of male patients was 153 ( 65. 7%) and the number ratio of male to female was 1. 9:1. The average age of them was (52. 7±11. 3), and most of them were middle-aged and elderly people living in the rural area (78. 1%) and were farmers ( 66. 1%) with low literacy (59. 7%). In 233 cases, 188 cases (80. 7%) possessed a clear history of ocular trauma, mainly caused by plant-based trauma (60. 9%). 90 cases (57. 3%) were infected with Fusarium, and 47 cases ( 29. 9%) by Aspergillus. The main treatment of severe fungal keratitis was surgery (87. 9%). 83 cases ( 52. 9%) were treated with penetrating keratoplasty, and in Fusarium and Aspergillus infected patients with severe fungal keratitis, 58. 4% ( 80/137 ) were performed with penetrating keratoplasty. In addition, patients treated with eye enucleation or evisceration, 68. 4% (13/19) were infected with Fusarium species.
CONCLUSION: Patients with severe fungalkeratitis in our hospital are mainly elderly male farmers living in rural, because of low economic condition and poor diagnosis consciousness. The main pathogens are Fusarium and Aspergillus species, and the major treatment is penetrating keratoplasty. Most of patients with poor clinical outcomes are infected with Fusarium species.

To explore the method of explants directly induced bud and establish the tissue culture system of mutiple shoot by means of direct organogenesis, core bud and daughter bulbs (the top of bud stem expanded to form daughter bulb) of T. edulis were used as explants and treated with thidiazuron (TDZ) and 1-naphthlcetic acid (NAA). The results showed that the optimal medium for bud inducted form core bud and daughter bulb were MS + TDZ 2.0 mg x L(-1) + NAA 4.0 mg x L(-1) and MS +TDZ 2.0 mg x L(-1) + NAA 2.0 mg x L(-1) respectively, both of them had a bud induction rate of 72.92%, 79.22%. The optimal medium for cluster buds multiplication was MS + TDZ 0.2 mg x L(-1) + NAA 0.2 mg x L(-1), and proliferation coefficient was 2.23. After proliferation, cluster buds rooting occurred on MS medium with IBA 1.0 mg x L(-1) and the rooting rate was 52.6%, three to five seedlings in each plant. Using core bud and daughter bulb of T. edulis, the optimum medium for adventitious bud directly inducted from daughter bulb, core bud and cluster bud multiplication were screened out and the tissue culture system of multiple shoot by means of direct organogenesis was established.

This study is to evaluate the therapeutic effect of fibroblast growth factor 21 (FGF21) on NAFLD in MSG-IR mice and to provide mechanism insights into its therapeutic effect. The MSG-IR mice with insulin resistance were treated with high dose (0.1 micromol.kg-1d-1) and low dose (0.025 micromol.kg-1d-1) of FGF21 once a day for 5 weeks. Body weight was measured weekly. At the end of the experiment, serum lipids, insulin and aminotransferases were measured. Hepatic steatosis was observed. The expression of key genes regulating energy metabolism were detected by real-time PCR. The results showed that after 5 weeks treatment, both doses of FGF21 reduced body weight (P<0.01), corrected dyslipidemia (P<0.01), reversed steatosis and restored the liver morphology in the MSG model mice and significantly ameliorated insulin resistance. Additionally, real-time PCR showed that FGF21 significantly reduced transcription levels of fat synthetic genes, decreased fat synthesis and promoted lipolysis and energy metabolism by up-regulating key genes of lipolysis, thereby liver fat accumulation was reduced and liver function was restored to normal levels. In conclusion, FGF21 significantly reduces body weight of the MSG-IR mice, ameliorates insulin resistance, reverses hepatic steatosis. These findings provide a theoretical support for clinical application of FGF21 as a novel therapeutics for treatment of NAFLD.

OBJECTIVETo investigate the interventional effect of comprehensive behaviour psychotherapy on the ejaculatory latency of premature ejaculation (PE) patients, sexual satisfaction of sexual partners, as well as its influence on the results of clinical treatment.

METHODSNinety PE patients were randomly divided into a psychological intervention group (n = 45) and a control group (n = 45). Both groups were given medicine therapy, and the former also received comprehensive behaviour psychotherapy for 6 weeks. All the patients were assessed with the Chinese index of sexual function for PE and ejaculatory latency in the vagina, and the clinical efficacy was compared between the two groups.

RESULTSBefore treatment, the ejaculatory latency in the vagina was (0.69 +/- 0.25) min and (0.71 +/- 0.19) min respectively in the intervention and the control groups, as compared with (5.87 +/- 0.59) min and (4.76 +/- 0.54) min before treatment, with significant difference (P < 0.01). In the intervention group, the scores in the control of ejaculatory reflex, the sexual satisfaction of the patients and their sexual partners and anxiety or depress in sexual activity in CIPE were higher than in the control group, with significant difference between the two groups (t = 2.12, 2.31, 2.01, 2.24, P < 0.05). The difference in the SAS score after therapy was of significance (P < 0.01). A month after treatment, the effectivity rates of the two groups were 82.9% and 30% respectively, and the difference was significant (P < .01).

CONCLUSIONComprehensive behaviour psychotherapy obviously adds to the clinical efficacy of drugs in the treatment of PE.

AIMTo explore whether the oligonucleotide uptake in hematological tumor cells is related to cellular species and proliferation.

METHODSIntracellular mean fluorescence intensity was measured by flow cytometry.

RESULTSAfter treatment with FITC-labeled G3139 at the concentration of 0.60 mumol.L-1 for 4 h, the G3139 uptake into peripheral blood mononuclear cell and bone marrow mononuclear cell in hematological tumor patients was significantly higher than that in normal control. There was different uptake of G3139 among the malignant hematological tumor cell strains, and the uptake in cells derived from monocyte, B lymphocyte and myeloid cell was much higher than that in cells derived from T lymphocyte. After treatment with all-trans retinoic acid (ATRA), HL60 cell proliferation was markedly inhibited and the uptake of G3139 decreased significantly.

CONCLUSIONHematological tumor cells were capable of taking up oligonucleotide, and the oligonucleotide uptake in hematological tumor cells is related to its cellular species and its activation.

OBJECTIVETo induce the differentiation of K562/MDR1 cells into dendritic cells (DC) with multidrug resistance property.

METHODSK562/MDR1 cells and K562 cells were cultured in the presence of GM-CSF and IL-4 to generate DC and matured by TNF-α. On d14 K562/MDR1-DC and K562-DC cells were harvested and the expressions of CD1a, CD83, CD80, CD86, HLA-ABC and HLA-DR were assessed by flow cytometry (FCM). The antigen presentation function of K562/MDR1-DC and K562-DC was determined by allogenic mixed lymphocyte reaction (Allo-MLR). The expression of P-glycoprotein and the intracellular accumulation of daunorubicin (DNR) were detected by FCM. The sensitivity of K562/MDR1-DC and K562-DC cell to vincristine, adriamycin was measured using MTT assay.

RESULTSBoth K562/MDR1 and K562 cells were differentiated into dendritic cells in the presence of cytokine cocktails, showing the morphologic and immunophenotypic characteristics of DC. K562/MDR1-DC more markedly enhanced proliferation of allogeneic lymphocytes in MLR than K562-DC. High level expression of P-glycoprotein and efflux of DNR were demonstrated in K562/MDR1-DC. K562/MDR1-DC showed multidrug resistance property, with higher IC(50) to VCR and ADM than that of K562-DCs.

CONCLUSIONK562/MDR1 cells can be differentiated into DC with the presence of cytokines, the induced K562/MDR1-DC cells express high level of P-glycoprotein and acquire the multidrug resistance property.
