Objective:The time-dependent changes of hypoxia-inducible factor-1? (HIF-1?) expression induced by CoCl_(2 ) treatment and the effects of genistein on the level of HIF-1? expression in human retinal pigment epithelium cells were studied. Methods:Using a confocal scanning laser microscope coupled to a computer, HIF-1? expression was determined. Results:CoCl_(2 ) treatment could significantly elevate the level of HIF-1? expression. At 0.5 hour after CoCl_(2 ) treatment, the highest level was observed. Genistein 50 ?mol/L, 100 ?mol/L, 200 ?mol/L could suppress HIF-1? expression in a concentration-dependent manner. Conclusions:These results suggested that genistein could inhibit HIF-1? expression induced by CoCl_(2).

Objective To discuss the application and effect of predictive care in stage divided treatment and salvage of children's persistent status of epilepsy (SE).Methods Sixty-four children with SE were admitted to the First Peoples Hospital of Wenling in Zhejiang Province from December 2014 to December 2016 as the research objects, a controlled study was adopted, in which the stage divided therapeutic method was compared with the conventional method for treatment of SE, and the children were divided into an observation group and a control group, 32 cases in each group. Foresight treatment method was used in the observation group: the first stage of treatment (early treatment or pre-hospital treatment) was intravenous injection of the first-line drugs (benzodiazepines); the second stage of treatment (progressive stage treatment or initial treatment) mainly used epileptic drugs to prevent recurrence; the third stage treatment (referred to after the first-line drug in combination with one second line antiepileptic drug treatment, the disease was still unable to be controlled) adopted the mild hypothermia therapy to reduce the SE attack amplitude and decrease recurrence; in terms of aspects of predictive nursing measures, the respiratory tract nursing, basic nursing, the prediction of complications and their nursing, etc. were implemented. The routine nursing without care about the stages was carried out in the control group. The SE control time, skin lesions, false aspiration, lung infection, tongue bite, cerebral edema, etc. the incidenceof complications were observed in two groups of children.Results The SE control time was significantly shorter in observation group than that in the control group (minutes: 18.13±3.15 vs. 25.19±2.69,P < 0.05), and the incidence of complications was obviously lower in observation group than that in the control group [6.25% (2/32) vs. 28.13% (9/32),P < 0.05]. Conclusion Using different therapy at different stages of children SE combined with predictive care can effectively shorten the SE control time, decrease the incidence of complications and elevate the therapeutic and nursing effects.

Objective To observe the learning and memory ability,oxidative stress,apoptosis morphological changes in the hippocampus,and to explore the effects of hyperuricemia on cognitive function.Methods 51 healthy male SD rats were randomly divided into three groups (17 in each group):Blank group,Distilled water group and Hyperuricemia group.Using the lavage methods of yeast extract combined with ethambntol to establish hyperuricemic model.Morris water maze test was used to measure the learning and memory ability.The levels of MDA,GSH-Px,ASAFR,SOD were measured through chemical colorimetry.Hippocampus morphology structures were observed under the HE staining light microscopy to detect the apoptosis of hippocampus cone cell with TUNEL.Results The average escaped latency and passing platform times of Blank group had no significant difference compared with those of Distilled water group and Hyperuricemia group (all P＞ 0.05).GSH-Px,ASAFR,SOD of Hyperuricemia group ((83.70 ± 5.47) nmol/mg,(606.03±46.61) U/L and (55.05 ± 2.11) units/mg) were increased compared with those of Blank group ((67.28±8.37) nmol/mg,(473.84 ± 57.64) U/L,(45.79 ± 2.05) units/mg) and Distilled water group ((71.96±9.47) nmol/mg,(505.97 ± 47.19) U/L,(46.24 ± 3.65) units/mg) (all P＜ 0.05).Compared with Blank group ((3.19±1.14) μmol/L) and Distilled water group ((3.16±1.43) μmol/L),the MDA of Hyperuricemia group ((1.74±0.45) μmol/L) was significantly decreased (all P＜ 0.05).Form and structures of hippocampal neurons of each group were basically normal under the HE staining light microscopy.Compared with Blank group (CA1:(3.59±0.63) ％,CA3:(5.54± 0.78) ％) and Distilled water group (CA1:(3.25±0.97) ％,CA3:(5.96± 0.82) ％),the hippocampal cells of Hyperuricemia group (CA1:(4.04± 0.78) ％,CA3:(5.95±0.80) ％) also had no statistical differences (P＞0.05).Conclusion Hyperuricemia has antioxidant effect on hippocampal neurons and has no effect on cognitive function and hippocampal neural morphology in rats.

OBJECTIVETo explore activity laws of mitochondrial complex II in patients of deficiency-cold syndrome (DCS) and deficiency-heat syndrome (DHS) under various ambient temperatures.

METHODSSubjects were recruited by questionnaire and expert diagnosis from grade 1 - 3 undergraduates at Henan College of Traditional Chinese Medicine in November 2012, and assigned to a normal control group, the DCS group, and the DHS group, 20 in each group. Their venous blood samples were collected at two different temperature conditions. Activities of mitochondrial complex II were measured by spectrophotometry.

RESULTS(1) Comparison of mitochondrial complex It under various ambient temperatures: Compared with room temperature in the same group, activity values were all increased in the normal control group at cold temperature with significant difference (P <0.05), but there was no significant difference in the DCS group and the DHS group (P >0. 05). Compared with the normal control group, activity values of complex H were reduced in the DCS group at cold and room temperatures with significant difference (P <0.05). Compared with the DCS group, activity values of complex It were increased in the DHS group with significant difference (P <0. 05). (2) Changes of adjustment rates: Compared with room temperature, the adjustment rate all rose at cold temperature in the normal control group and the DHS group with significant difference (P <0.05), but with no significant difference found in the DCS group (P >0. 05). Compared with the normal control group at the same temperature, the adjustment rate in the DHS group and the DCS group was all reduced at cold and room temperatures with significant difference (P <0. 05). There were no significant difference in the adjustment rate between the DHS group and the DCS group (P > 0. 05).

CONCLUSIONSEnvironment temperature can affect the activity of mitochondrial complex II with different influence degrees on different syndrome types of people, but its change trend are basically identical.

Aim: Clone and characterize of the 5′- flanking region of the nitrate reductase (NR) gene derived from Dunaliella salina(D. salina). Methods : The genomic DNA from D. salina was respectively digested with BamHI, EcoRI, HindIII, Pst I, Sal I and Xba I. A genomic walking cassette was ligated to the ends of the digested DNA fragments, and then genomic walking libraries comprising BL, EL, HL, PL, SL and XL were constsucted. The 5′- flanking region of the NR gene from genomic walking libraries of D. salina was amplified by LA-PCR. The DNA sequences were analyzed with the software - Promoter Predictions. Isolated 5′-flanking regions fused to the GUS gene were tested for transient expression in the alga. Results: A single specific PCR product of about 1200bp in length from the HL library was generated. Also, several conserved motifs, such as CAAT-box, GAGA-box were found, which are related to regulation of transcription, and the putative binding sites of transcriptional factors such as EBP, EFII, NF-E1 and LV. BLAST showed that the DNA sequences shared high homology with 5′-upstream region of the NR gene from Dunaliella viridis. The isolated 5′-flanking regions were able to strongly drive GUS reporter gene expression, suggesting that it contains the promoter elements necessary for the transcription of the NR gene. The expression pattern of the GUS gene and the NR gene were similar, both ware induced by nitrate and repressed by ammonium. Conclusion: The cloned 5′- flanking sequences of NR gene derived from D. salina might be a specific promoter with the ability to“switch on or off” an expression of the heterologous gene in transgenic D. salina.

OBJECTIVE To assess the effect of Ibudilast on the quality of life (QOL) of patients with steroid resistant allergic rhinitis.METHODS A randomized,double-blind,placebo-controlled study was carried out with Ibudilast in 66 patients with the steroid resistant allergic rhinitis.QOL was measured with Short-Form Health Survey (SF-36) questionnaire (Chinese version).Ibudilast (10rag twice daily,34 patients),placebo (32 patients) was given for 3 weeks. The SF-36 questionnaire was administered at the start of treatment and after 3 weeks of treatment.Sings and Symptom-medication scores were measured daily during the study.RESULTS There were no significant differences between the Ibudilast and placebo group in terms of sings and symptoms or QOL scores before study.After 3 weeks of treatment,symptoms scores were significantly decreased and QOL scores significantly improved in the Ibudilast group compared with those in placebo group (both P

Objective:To analyze the relationship between free androgen index and insulin function in obese young men aged from 20 to 35.Methods:A total of 82 young obese men in Obesity Clinic from February to October 2019 were enrolled in the study. The subjects were divided into 3 subgroups according to free androgen index level tertiles. The blood glucose and insulin levels were tested after oral glucose tolerance test. Homeostasis model assessment for insulin resistance (HOMA-IR), homeostasis model assessment for β cell function (HOMA-β), insulin secretion index, and insulin sensitivity index (Matsuda index) were used to evaluate β cell function in oder to analyze the relationship between free androgen index and insulin function.Results:In young obese men, participants with higher free androgen index levels exhibited less waist circumference, lower body mass index, 1 h postprandial insulin, 2 h postprandial insulin, HOMA-IR level but with a higher total testosterone, sex hormone binding globulin, and Matsuda index level (all P<0.05). There was a negative correlation between the free androgen index and the HOMA-IR ( r=-0.386, P=0.016), and the correlation tended to a linear trend after adjustment for age, sex, body mass index, and waist circumference ( Ptrend=0.034). Free testosterone was positively correlated with Matsuda index ( r=0.280, P=0.004), but the correlation disappeared after adjustment ( Ptrend=0.623). The results of further regression analysis showed that the level of free testosterone index decreased by 14.1% ( OR=0.869, 95% CI0.767-0.984, P=0.028) for each increase of HOMA-IR after adjustment. Conclusion:The level of free testosterone index is a predictor of insulin resistance in obese young men, but the association between this parameter and insulin sensitivity may be caused by obesity.

OBJECTIVETo investigate the expression and significance of CD151 in pituitary adenomas.

METHODSThirty-six pituitary adenomas were collected immediately after surgery together with five normal pituitary tissue. Real time-PCR, Western blot and immunohistochemistry analysis were performed to detect the expression of CD151 mRNA and protein in thirty-six pituitary adenomases and five normal pituitary tissues.

RESULTSThe expression of CD151 in all pituitary adenomases was observed to be significantly higher than that in normal pituitary tissues by Western blot, real time PCR, and immunohistochemistry analysis (P < 0.01). The expression levels of protein and mRNA in invasive pituitary adenomas were much higher than those in non-invasive pituitary adenomas (P < 0.01).

CONCLUSIONThe results suggested that the expression of CD151 was closely correlated with malignant degree of pituitary adenomas, which indicated the expression of CD151 was intimately correlated with occurrence and development of pituitary adenomas. Detecting CD151 might be a vital index to predict prognosis of pituitary adenomas.

OBJECTIVETo study the clinical effect of combination of kurarinone (KR) and interferon a-lb (IFNalpha-1b) in treating chronic hepatitis B.

METHODSOne hundred and forty-six patients with chronic hepatitis B were randomized into four groups. Under the basic conventional treatment, additional KR combined IFNa-lb was given to Group A, IFNa-lb to Group B and KR to Group C while none was given to Group D. The therapeutic course for them was 6 months and succeeded with 6 months of follow-up. Changes in liver histology, expression of transforming growth factor beta (TGF-beta) in liver tissue, and serum levels of TGF-beta, hyaluronic acid (HA), laminin (LN), collagen type IV (IVC), precollagen III (PCIII), as well as the negative conversion rate of HBeAg and HBV DNA, and normalization rate of alanine transaminase (ALT) before and after treatment were observed by immuno chemical method, RIA and ELISA.

RESULTSAfter treatment, in Group A, the scores of liver fibrosis and all the above-mentioned indexes significantly lowered, as compared with those in Group B and C, the difference was significant (P<0.05 or P<0.01). The negative conversion rate of TGF-beta in liver tissue was in accordance with the dynamic change of liver fibrosis. Comparison between Group B and C in those aspects showed insignificant difference (P >0.05).

CONCLUSIONKR combined with IFNalpha-1b shows better effect in treating chronic hepatitis B than that of using either of the two alone.
