BACKGROUND: Retinitis pigmentosa (RP) is a non-inflammatory, bilaterally progressive, retinal degeneration characterized by loss of photoreceptor cells via an apoptotic mechanism, and it eventually leads to blindness.Research shows that the traditional Chinese medicines of Astragalus has great prospect on blocking the progression of RP disease.OBJECTIVE: To observe the protective effect of Astragalus on N-methylN-nitrosourea (MNU)-induced retinal damage in Sprague-Dawley (SD) rats and provide the optimal treatment for RP in humans.DESIGN: Randomized controlled experiment.SETTING: School of Pharmaceutical Sciences, Xinxiang Medical College.MATERIALS :The experiment was completed in Pharmacological Laboratory of Zhongshan Ophthalmic Centre, Sun Yat-sen University between March to December 2004. Totally 114 female SD rats were purchased from the Animal Center of Zhongshan Medical College, Sun Yat-sen University.MNU was purchased from Sigma Company of America. Astragalus injection was purchased from Chengdu Diao Jiuhong Pharmaceutical Factory (Batch No. Z99060535, 2 mL/ampoule, main ingredient: Astragalus).METHODS: Among 114rats, 30 were for morphometric analysis of retinal layers, 30 were for detection of apoptosis and 54 were for detection of NF-κB p65 activity. All of them were randomly divided into different groups and each group had 6 rats. Astragalus at doses of 2.5, 5 and 10 g/kg were injected intraperitoneally into 47-day rats once a day. Meanwhile, a single intraperitoneal injection of 60 mg/kg MNU was given to 50-day rats in model and Astragalus groups. At different intervals after MNU treatment,the animals were sacrificed. Retinal damage was evaluated based on retinal thickness, the apoptotic index of the photoreceptor cells was detected by TUNEL labeling and the DNA-binding activity of NF-κB p65 was analyzed according to transcription factor assay kit.MAIN OUTCOME MEASURES: Comparison of retinal thickness, apoptotic index and the activity of nuclear NF-κB p65.RESULTS: Totally 114 rats entered the result analysis. Pretreatment with Astragalus could dose-dependently suppress MNU-induced photoreceptor cell loss and decreased the apoptotic index. Astragalus at dose of 10 g/kg also time-dependently up-regulated the activity of nuclear NF-κB p65.However, protective effect of Astragalus on MNU-induced central retinal damage was not found.CONCLUSION: Astragalus partially protects against MNU-induced retinal damage by up-modulating the activity of nuclear NF-κB p65 to inhibit apoptosis of photoreceptor cells in a dose-dependent manner.

Objective To investigate the association between single nucleotide polymorphism (SNP) of macrophage migration inhibitory factor (MIF) gene-rs1007888 and the pathogenesis of gestational diabetes mellitus (GDM).Methods A total of 120 GDM pregnant women (GDM group) and 165 healthy pregnant women (control group) from Affiliated Hospital of Medical College,Qingdao University were recruited from June 2011 to July 2012.Their age,gestational week,height and weight were recorded.The levels of fasting blood glucose (FBG) and fasting insulin (FIN) were determined.Body mass index (BMI),the hemeostasis model assessment-insulin resistance (HOMA-IR) and hemeostasis model assessment-β cell function (HOMA-β) were calculated.DNA was extracted from fasting blood samples.SNP of MIFrs1007888G/A was determined by DNA sequencing.The FBG,FIN,HOMA-IR and HOMA-β were compared between GDM group and the control group.They were also compared among pregnancies withdifferent genotypes.Results (1) GDM group had higher FBG,FIN and HOMA-IR levels,but lower HOMA-β than the control group (all P ＜ 0.05).(2) MIF-rs1007888 SNP genotype frequencies of GG,GA and AA were 37.5％,45.8％ and 16.7％,and the allelic frequencies of G and A were 60.4％,39.6％ in GDM group; However,in the control group,the frequencies of GG,GA and AA were 26.1％,54.5％ and 19.4％,and the allelic frequencies of G and A were 53.3％,46.7％,respectively.The distributions of MIF genotypes in GDM patients were significantly different from the healthy subjects (P ＜ 0.05).No significant difference of MIF-rs1007888 allele distributions was observed between GDM group and the control group (P ＞0.05).(3) The FBG,FIN and HOMA-IR in pregnant women with GG genotype were statistically higher than those with GA or AA genotypes,while HOMA-β was lower in women with GG genotype (all P ＜0.05).Conclusions The SNP of MIF rs-1007888 was related to the insulin resistance and pancreatic β cell function of pregnant women.GG genotype of MIF-rsl007888 might be a genetic susceptible factor in the pathogenesis of GDM.

Objective To investigate the clinical characteristics and treatment of acute postrenal acute renal dysfunction associated with ceftriaxone.Methods Twenty-five cases of the ceftriaxione-associated acute postrenal renal insufficiency were reviewed.There were 16 males and 9 females,mean age 28years.The serum contents of BUN and Cr were ( 18.6 ± 7.0) mmol/L and (635.5 ± 248.7 ) μmol/L,respectively.All patients were divided into two groups depending on the therapy:11 patients accepted the drug therapy (alkalinization of the urine,antispasmodic,etc) and 14 patients accepted the intraureteral cannula.The clinical characteristics and the treatment effect were compared between the 2 groups.Results The patients of the intraureteral cannula group ( 1.4 ± O.7 d) went to hospital earlier than the drug therapy group (3.0 ± 1.4 d) ( P =0.045 ) after the symptom of oliguria or anuria appeared.There were no significant differences in serum creatinine,urea nitrogen,and the age between the 2 groups ( P ＞ 0.05 ).All the patients were cured after treatment.There were no significant differences in recovery time (2.9 ± 1.1 d and 3.2 ± 1.2 d,P =0.963) and hospitalization time (7.0 ±2.3 d and 5.9 +3.9 d,P =0.568) between the 2 groups.Conclusions The acute renal failure associated with ceftriaxone should have high attention.The prompt medical attention,including the intraureteral eannula and the drug therapy,can both achieve the satisfying curative effect.

Objective To construct extravillous trophoblast(EVCT) tissue microarray and detect the expression of phosphorylated signal transducer and activator of transcription 3 (pStat3) in EVCT and to explore the role of Stat3 signal transduction pathway in the pathogenesis of preeclampsia.Methods Placentas of 80 pregnant women with preeclampsia and 58 normal pregnant women hospitalized in the Third Affiliated Hospital of Zhengzhou University from December 12,2007 to December 31,2010 were recruited for constructing EVCT tissue microarray.Vimentin,cytokeratin and human leukocyte antigen-G were used to verify EVCT tissue microarray immunohistochemically.The difference of pStat3 expression was detected between preeclampsia patients and normal pregnant women by immunohistochemical staining.Rank sum test,Kruskai-Wallis H test,t-test and Chisquare test were used for statistical analysis.Results Placental tissues from 57 preeclampsia patients (109 tissue cores) and 31 normal pregnant women (65 tissue cores) were suitable for constructing EVCT tissue microarray.The target tissue was positive for both cytokeratin and human leukocyte antigen-G staining and negative for vimentin,which was in accordance with the characters of EVCT tissue.Totally 86.4％(76/88) samples retained the target EVCT tissues,which meant EVCT tissue microarray was constructed successfully.The expression of pStat3 was significantly decreased in EVCT of preeclampsia patients (51.1％,24/47),the early onset (50.0％,19/38) and severe preeclampsia patients(52.3％,23/44) as compared to normal pregnant women (72.4％,21/29) (U=492.00,473.00 and 401.00,P＜0.05 respectively).Conclusions EVCT tissue microarray has been successfully constructed,and could be used to detect pStat3 expression.pStat3 signal transduction pathway may be involved in the development of preeclampsia.

Objective To investigate the expression of macrophage migration inhibitory factor (MIF) and CD_(74), the receptor of MIF, in preeclamptic placenta and its correlation with the pathogenesis of preeclampsia.Methods From March 2008 to November 2008,69 preeclamptic women who delivered in the Department of Obstetrics, Affiliated Hospital of Qingdao University Medical College,were recruited,including 33 women with mild preeclampsia (MPE group) and 36 women with severe preeclampsia (SPE group).Another 43 healthy pregnant women were taken as control group.Immunoturbidimetry was applied to measure the concentrations of C-reactive protein (CRP) in maternal blood.The expressions of MIF and CD_(74) in placenta were tested with immunohistochemistry and the expressions of MIF mRNA and CD_(74) mRNA were detected by semiquantitative RT-PCR.The relationship between maternal blood level of CRP and MIF mRNA and CD_(74) mRNA in placenta was analyzed in the MPE and SPE group.Results (1) MIF and CD_(74) were expressed in the placenta of all pregnant women in the 3 groups, as shown in brown-yellow color, and significantly higher expression was found in the MPE and SPE group.(2) The expression of MIF mRNA and CD_(74) mRNA in the MPE group (0.70±0.13 and 0.96±0.16), SPE group (0.88 ± 0.12 and 1.08 ± 0.15) were significantly higher than in the control group (0.67 ± 0.11 and 0.83 ± 0.14) (P < 0.01), and statistical significance was also found between the MPE and SPE group (P <0.01).(3)The maternal blood concentrations of CRP in the MPE and SPE group were significantly higher than in the control group [(15.3±7.0) mg/L and (21.6±9.1)mg/L vs (4.8 ± 1.8) mg/L, P <0.01] , and significant difference was also found between the MPE and SPE group (P <0.01).(4) In the two preeclamptic groups, the blood concentrations of CRP were positively correlated with the expression of both MIF mRNA(r =0.67 ,P <0.01)and CD_(74) mRNA(r =0.83 ,P <0.01) in placenta.Positive correlation was also found between the levels of MIF mRNA and CD_(74) mRNA in placenta (r =0.93 ,P < 0.01).Conclusions Overexpression of MIF and CD_(74) in the placenta may up-regulate the CRP level in maternal blood, resulting in systemic inflammatory reaction and vascular endothelium damage which may be involved in the pathogenesis of preeclampsia.
