Objective To study the clinical manifestations and surgical treatment in renal transplant recipients with benign prostatic hyperplasia (BPH). Methods From January 2013 to May 2015, 5 patients of kidney transplant recipients who suffered from BPH for transurethral resection of prostate (TURP) treatments were enrolled (kidney transplant recipients group) and 15 patients with the same surgical treatments during the same peoriod were enrolled too (common control group). The routine examination, urodynamic, sex hormone levels and and the clinical efficacy were observed. Results The levels of hemoglobin, total protein, urea nitrogen, creatinine, prostate volume , residual urine and maximum flow rate (Qmax) before operation between two groups had no significant differences (P>0.05). The level of testosterone in kidney transplant recipients group was significantly lower than that in common control group: (3.5 ± 1.2) mmol/L vs. (5.5 ± 2.2) mmol/L, P < 0.05. The level of estradiol in kidney transplant recipients group was significantly higher than that in common control group:(49.6 ± 13.8) mmol/L vs. (40.5 ± 16.4) mmol/L, P < 0.05. In kidney transplant recipients group, the levels of hemoglobin, total protein, urea nitrogen, creatinine before and after operation had no significant differences (P>0.05). After operation, the levels of hemoglobin, total protein, urea nitrogen, creatinine in two groups had no significant differences (P>0.05). In kidney transplant recipients group, the quality of life (QOL) score before operation was 5 scores in 4 cases and 6 scores in 1 case, and those after operation were zero in 3 cases and 1 score in 2 cases. Conclusions Under the sufficient preoperative preparation and assessment, the renal transplant recipients with BPH patients can improve the symptoms of urinary obstruction and obtain satisfactory clinical efficacy as common BPH patients.

Background:Pancreatic cancer is obscure in onset and progresses rapidly with very poor prognosis. Photodynamic therapy( PDT)has been developed as a novel anti-tumor treatment modality since 1980s. At present,there are only limited researches on pancreatic cancer treated with PDT in vivo. Aims:To investigate the efficacy of quantum dots-RGD ( QDs-RGD)based PDT combined with gemcitabine for treatment of pancreatic cancer xenograft in nude mice. Methods:QDs-RGD probe was synthesized and nude mice bearing pancreatic cancer xenograft was established. Nude mice were imaged at 1,5,10 and 24 hours after injection of QDs-RGD and QDs by in vivo imaging system. Forty model nude mice were randomly divided into five groups:control group( without any treatment),simple illumination group( laser 630 nm, 120 J/cm2,20 min),PDT group(QDs-RGD 0. 5 nmol+laser irradiation),gemcitabine group(gemcitabine 50 mg/kg)and combination group(QDs-RGD 0. 5 nmol+laser irradiation+gemcitabine 50 mg/kg). All the nude mice were sacrificed 18 days later. Tumor weight and volume were measured and tumor inhibition rate was calculated. Results:Fluorescence of tumor was shown 1 hour after injection and became clearest at the 5th hour,then showing a decrescendo trend. Density of QDs surrounding tumor was significantly less than that of QDs-RGD and faded away at the 10th hour. Tumor weight and volume in PDT group,gemcitabine group and combination group were all significantly lower than those in control group and simple illumination group(P<0. 01),and those in combination group were significantly lower than those in PDT group and gemcitabine group(P <0. 05). No significant differences in tumor weight and volume were found between control group and simple illumination group(P >0. 05),as well as between PDT group and gemcitabine group(P >0. 05). Tumor inhibition rate in combination group,gemcitabine group and PDT group was 70. 5%,43. 5% and 37. 1%, respectively. Conclusions:QDs-RGD based PDT combined with gemcitabine can inhibit the growth of pancreatic cancer xenograft in nude mice,which introduces a new idea to the treatment of pancreatic cancer.

Objective To investigate the effect of double lumen tube applied in the simple negative pressure drainage.Methods Forty cases were divided into two groups by a random table method,with 20 cases in each group. The double lumen tube was used in observation group while the normal gastric tube was used in control group,then the indexes on the drainage effect and wound healing were quantized and analyzed.Results In the observation group,one case suffered obstruction at 2 -4 days,1 case after 4 days of treatment,the obstruction rate was 10%.In the control group,two cases suffered obstruction at 2 -4 days,and 2 cases after 4 days of treatment,the obstruction rate was 25%.There was significant difference between two groups(χ2 =9.212,5.021,P =0.027,0.032).There were two cases of delayed healing and 17 cases with effective in the observation group,but 8 cases delayed healing and 11 cases with effective in the control group,there was statistically significant difference (χ2 =5.833,4.800,P =0.016, 0.028).Conclusion Double lumen tube can delay the occurrence time and reduce the occurrence rate of obstruction in simple negative pressure drainage,which promotes wound healing,and it is worth popularizing and using clinically.

Objective To study the relationship between apoE alleles and the occurrence of sporadic Alzheimer's disease (SAD) and to compare the alleles relating to the SAD and the vascular dementia (VD). Methods The polymorphism of apoE gene was detected using polymerase chain reaction restriction fragment length polymorphism(PCR RFLP) technique for 58 patients with SAD, 59 patients with VD and 60 normal controls. Results The frequencies of the ?4 and 3/4 genotype in SAD group(19 82% and 25 86%)were significantly higher than those in the controls(5 00% and 6 67%, ? 2=13 87, P 0 05). Conclusions The apoE ?4 allele is a genetic risk factor for the occurrence of SAD.

Objective To investigate the value of interphase fluorescence in situ hybridization(FISH)technique and the detection of fusion gene in the diagnosis of acute myeloid leukemia(AML)M2 and M3 Methods FISH was used to detect the AML1/ETO fusion gene and/or PML/RARα fusion gene in incipient cases including 9 AML-M2, 12 AML-M3 and 10 AML undetermined as AML-M2 or AML-M3 primarily diagnosed by routine morphology though bone marrow,cytochemical staining and immunophenotyping,which can help diagnose and guide clinical therapy.Results 4 of 9 AML-M2 cases were AML1/ETO positive.Among 12 AML-M3 cases,10 were PML/RARα positive.1 case was detected AML1/ETO fusion gene.In 10 untonfirmed M3 or M2,3 case8 showed AML1/ETO,5 showed PMIJRARot fusion gene and the rest showed neither of the genes.Conclusion As a new technique of the molecular genetics,FISH is accurate, rapid and efficient.It would be of significance not only at diagnosis of AML,but also for subsequent clinical decision-making.
