Objective To discuss the influence of blood exchange transfusions on hemato- microenvironment of neonates with hyperbilirubinemian.Methods Blood exchange transfusion was performed in 35 neonates.Mean transfusion volume was (136.9±27.4) ml/kg.The speed of blood exchange transfusion was 92 ml/(kg·h).Blood bilirubin,blood electrolyte,blood routine and blood sugar levels were measured before,during and after the transfusion.Results Serum total bilirubin (TB) decreased by 53.78% after blood exchange,but there was no change in Na~+,Cl~-,and blood sugar (P＞0.05),and K~+ was remarkably decreased from (4.45±2.40)mmol/L to (3.87±0.52)mmol/L (t=21.979,P＜0.05).TB,Hb,PLT,WBC,Ca~(2+) were decreased[TB from(511.52±80.21) μmol/L to (236.41±66.54) μmol/L;Hb from (145.20±11.70) g/L to (128.66±2.54) g/L;PLT from (207.84±70.67)×10~9/L to (134.86±48.61)×10~9/L;WBC from (16.90±10.56)×10~9/L to (8.94±7.44)×10~9/L,and Ca~(2+) from (1.26±0.32) mmol/L to (0.99±0.22) mmol/L,P＜0.05 or ＜0.01].Conclusions Blood exchange transfusion can not influence Na~+,Cl~-,and blood sugar,but has remarkable effect on total bilirubin,Ca~(2+),Hb,K~+,PLT,and WBC.

Objective To investigate the expression of DNA methyltransferase 1 (DNMT1)mRNA in tissue of human transitional cell carcinoma of bladder(TCCB)and its clinical significance.Methods DNMT1 mRNA expression in 35 tumor tissues and 10 normal bladder tissues was measured by real-time PCR.Results Higher expression of DNMT1 transcripts was detected in tumor(3.25±0.74)than in normal tissues(1.53±0.44,P＜0.001).The expression level of DNMT1 mRNA in stage Tis-T1,T2-T4 was 3.14±0.67,3.31±0.84;in grade Ⅰ,Ⅱ,Ⅲ was 3.13±0.59,3.25±0.64,3.43±0.55;in patients older tham 40 years and younger than 40 years was 3.34±0.50.3.01±0.27;in male and female group was 3.31±0.42,3.01±0.20;in primary and recurrence group was 3.21±0.63,3.45±0.33.mRNA levels did not correlate with grade.stage and recurrence (P＞0.05).Higher levels of expression were associated with advanced age(P＜0.05).Male group had significant higher levels of expression than female group(P＜0.05).Conclusions Over-expres-sion of DNMT1 may play an important role in TCCB.DNMT1 can be an important therapeutic target in TCCB.

Objective To investigate the possible association between the CCND1 A870G polymorphism and susceptibility to prostate cancer(PCa)in a Chinese population.Methods The CCND1 A870G genotypes were determined by TaqMan assays in 245 PCa cases and age-matched 245 controis.Odds ratios(OR)for PCa and 95%confidence intervals(CI)from unconditional logistic regression models were used to evaluate relative risks.Age,a potential PCa risk factor,was included in the logistic regression models as a covariate in the multivariate analyses on genotype and PCa risk.Results The frequencies for G and A alleles were 0.476,0.524 in PCa cases,and 0.408 and 0.592 in controls,respectively.The G allele was marginally significantly associated with the presence of PCa (P=0.054)and had an increased risk for PCa(OR=1.31,95%CI=1.00-1.72)as compared to theA allele.Compared to AA homozygote,AG heterozygote had a 1.43-fold increased risk(95%CI=0.89-2.31,P=0.142),whereas GG homozygote had a significantly higher 2.02-fold increased risk (95%CI=1.07-3.80,P=0.029)of PCa(Armitage's trend test,P=0.029).The G allele(AG or GG genotype)was more frequently found in PCa patients with metastasis than those without metastasis(P=0.014).Conclusion The G allele of CCND1 A870G is associated with the presence of PCa and GG homozygote is potentially one of the genetic risk factors for PCa in Chinese population.The G allele may be associated with the progression of PCa metastasis.

Methods Totally 90 Wistar rats were inflicted to hyperbilirubinemia models and then divided randomly into 3 groups:untreated group (BG),treated-1 group (T_ 1 G), treated-2 group (T_ 2 G), and another 30 rats served as control group (CG). bFGF injection were given at 30 min, 1, 3, 5 and 7 d by abdominal cavity (T_ 1 G,) and cranial cavity (T_ 2 G). GAP-43 expression levels and the micro-morphological features were observed with immunohistochemical assay and transmission electron microscopy respectively at 2 nd, 8 st, 28 st and 60 st day. Results ①Hyperbilirubinemia rat model was verified by gross and microscopic observation, bilirubin concentrations in the plasma and brain.②Compared to CG, the expression level of GAP-43 was significantly up-regulated in BG, T_ 1 G and T_ 2 G, especially in the later 2 groups (P

Objective To investigate the methods of steroid supplement following adrenalectomy in the patients with Cushing syndrome.Methods The methods and outcome of steroid supplement following adrenalectomy in 75 cases of Cushing syndrome were retrospectively reviewed.Results Supraphysiological doses of glucocorticoid was given during the perioperative period,and the dosage was reduced gradually.Prednisone with a dosage of 5 to 7.5 mg was given once a day on discharge.In the patients with adrenocortical adenoma,4 to 15 month of steroid supplement was required.The patients undergoing bilateral adrenalectomy required lifelong steroid supplementation.Steroid withdrawal syndrome occurred during steroid tapering in 8 patients with adrenocortical adenoma,2 of them had normal plasma cortisol level.Conclusion In the patients with Cushing syndrome,even those with normal plasma cortisol level might have steroid withdrawal syndrome episodes during steroid tapering.

Objective: To investigate the factors associated with CD4⁺ /CD8⁺ T lymphocyte ratio normalization in acquired immunodeficiency syndrome (AIDS) patients after antiretroviral therapy (ART). Methods: The data of 1 188 human immunodeficiency virus (HIV)/AIDS patients from the national ART reporting system in Yuxi City, Yunnan Province between January 1, 2006 and December 31, 2016 were retrospectively collected and analyzed. The rate of CD4⁺ /CD8⁺ T lymphocyte ratio normalization after ART was calculated by lifetable. Cox proportional hazard models were used to analyze the factors associated with CD4⁺ /CD8⁺ T lymphocyte normalization in AIDS patients after ART. The Wilcoxon rank sum test was used for comparison between groups. Results: The follow-up time was 3.8 (1.0-10.8) years. CD4⁺ /CD8⁺ T lymphocyte ratio normalization was documented in 95 patients with the rate of 1.89 per 100 person-years (95% confidence interval(CI) 1.52-2.27) after ART. The average time from ART to CD4⁺ /CD8⁺ T lymphocyte ratio normalized was 9.4 years. The cumulative normalization rate was 0.02 for the first year, 0.06 for the third year, 0.11 for the fifth year, 0.19 for the seventh year and 0.37 for the ninth year. By Cox proportional hazard models, the probability of CD4⁺ /CD8⁺ T lymphocyte ratio normalization in patients infected HIV by heterosexual contacts was 3.709 (95%CI 1.781-7.726) times higher than those by intravenous injection. The probability of CD4⁺ /CD8⁺ T lymphocyte ratio normalization in patients with baseline CD4⁺ T lymphocytes of 350-499 and more than 500 cell/μL groups were 2.792 (95%CI 1.196-6.519) and 3.832 (95%CI 1.648-8.913) times higher than those with baseline CD4⁺ T lymphocytes less than 200 cell/μL, respectively. The probability of normalization after ART in patients with higher baseline CD4⁺ /CD8⁺ T lymphocyte ratio was higher than those with baseline CD4⁺ /CD8⁺ T lymphocyte ratio≤ 0.20 (hazard ratio>1, all P<0.01). Conclusion The CD4⁺ /CD8⁺ T lymphocyte ratio normalization in AIDS patients after ART is associated with baseline CD4⁺ T lymphocyte counts, baseline CD4⁺ /CD8⁺ T lymphocyte ratio and HIV transmission mode.

The role of serum and glucocorticoid-induced kinase 1 (SGK1) pathway in the connective tissue growth factor (CTGF) expression was investigated in cultured human mesangial cells (HMCs) under high glucose. By using RT-PCR and Western blot, the effect of SGK1 on the CTGF expression in HMCs under high glucose was examined. Overexpression of active SGK1 in HMCs transfected with pIRES2-EGFP-S422D hSGK1 (SD) could increase the expression of phosphorylated SGK1 and CTGF as compared with HMCs groups transfected with pIRES2-EGFP (FP) under high glucose or normal glucose. Overexpression of inactive SGK1 in HMCs transfected with pIRES2-EGFP-K127N hSGK1 (KN) could decrease phosphorylated SGK1 and CTGF expression as compared with HMCs groups transfected with FP under high glucose. In conclusion, these results suggest that high glucose-induced CTGF expression is mediated through the active SGK1 in HMCs.
