Objective To investigate the cell types of renal allograft intimal arteritis in posttransplantation patients and its relationship with peritubular capillaries (PTCs)C4d deposition. Methods Twenty allograft kidney transplant recipients from Jun 2006 to Jun 2008 were enrolled in the retrospective study. Twenty-one biopsy specimens with acute vascular rejection were immunostained for macrophages, T cells and C4d. In each biopsy specimen, arterial intimal macmphages and T cells were counted, and mean number of macrophages per "artery and T cells per artery were determined. The recipients were divided into C4d + and C4d- group according to whether C4d deposition in the PTCs. Results In the intimal arteritis of biopsies diagnosed as acute vascular rejection, the infiltrating cells were predominantly macrophages including C4d+ and C4d- group. T cells were the minority. The mean macrophage number per artery cross-section was significantly higher than the mean T cell number per artery cross-section in the C4d + group (12.45±9.86 vs 3.91±3.03, P=0.007) and in the C4d- group (3.47±1.89 vs 1.45±1.37, P=0.006). Forther more, the mean number of macrophage per artery cross-section in the C4d+ group was significantly higher than that in the C4d- group (P=0.007). Conclusions In the intimal arteritis of biopsies diagnosed as acute vascular rejection, the infiltrating cells are predominantly macrophages which has relationship with peritubular capillary C4d deposition. The mean number of macmphage per artery cross-section in the C4d+ biopsies is significantly higher than that in the C4d- biopses.

Objective To investigate the cell types of renal allograft glomerulitis in posttransplantation patients and its relationship with peritubular capillary (PTC) C4d deposition.Methods Fifty-one allograft kidney transplant recipients diagnosed as acute rejection from June 2006 to June 2009 in our center were enrolled in this retrospective study. Fifty-one biopsy specimens of these patients accompanied with glomerulitis were examined by immunostain for macrophages, T cells, granzyme B, Foxp3 and C4d. Glomeular macrophages, T cells, cytotoxic T cells, regulatory T cells were counted. The recipients were divided into C4d+ and C4d- groups according to the C4d deposition in peritubular capillaries. Results The total number of glomerular infiltrating cells in C4d+ group was significantly higher than that in C4d- group (17.79±7.70 vs 8.17±3.80, P<0.01). The infiltrating cell was predominantly macrophage in CAd+ group and significantly higher as compared to C4d- group (13.73 ±7.03 vs 2.57 ±1.22, P<0.01).However, the infiltrating cell was predominantly T cell in C4d- group and significantly higher as compared to C4d+ group (5.60±2.81 vs 4.05±2.60, P=0.023). The infiltrating T cells in both groups were predominantly cytotoxic T cells. Conclusions The total number of infiltrating cells in glomerulitis is related to peritubular capillary C4d deposition. The infiltrating cell is predominantly macrophage in C4d+ group and predominantly T cell in C4d- group. Meanwhile the infiltrating T cell in both groups is predominantly cytotoxic T cell.

Fourteen psychrotrophic bacteria were isolated from swamp soil collected in Ruoergai plateau wetland,and their generation time and degrading ability of livestock wastewater CODcr was determined.The results showed that the generation time was within 4.9 h to 11.6 h.Based on the generation time,9 psychro-trophic strains(NLJ1,NLJ6,NLJ7,NLJ9,NLJ10,NLJ11,NLJ12,NLJ13 and NLJ14),whose generation time was within 4.9 h to 5.6 h,were chosen to treat livestock wastewater.The results suggested that these 9 strains had different CODcr disposal ability when treating livestock wastewater singly at 6?C for 6 h,and strains NLJ6,NLJ7,NLJ9,NLJ10,NLJ11 and NLJ13 had good ability to degrade livestock wastewater,the CODcr degrading rate was about 60%~70%,hence,they were used as high efficient strains;However,the CODcr degrading rate of the other strains was less than 50%.After inoculating mixture culture of these six strains into the distilled livestock wastewater,after 6 h's treating,the CODcr degrading rate reached to 85.42%.Furthermore,activated sludge collected from Yaan,Dujiangyan and Chengdu were inoculated by the mixture culture of those six strains,and used to treat livestock wastewater for 6 h.The results showed that the average CODcr degrading rate was 81.67%,76.32% and 70.56%,respectively;Variance analysis showed that there was no significant differentiation between each treatment,which revealed that those six psychrotrophic strains had good adaptability to different source of activated sludge.

AIM: To retrospectively analyze selection of operation, surgery effect, complications and treatment methods of super high myopia combined with rhegmatogenous retinal detachment( RRD) .
METHODS:A total of 47 cases(47 eyes) with the super high myopia patients combined with RRD who accepted scleral buckling of external pressure, vitrectomy combined silicone oil filling, or intravitreous gas injection were chosen in our hospital from Jan. 1, 2011 to Jan. 1, 2016. Best corrected visual acuity ( BCVA), intraocular pressure, retinal reattached rate, closure rate of holes and the postoperative complications of patients in half year were analyzed.
RESULTS:Half a year postoperation, BCVA of twenty-four cases underwent vitrectomy combined silicone oil filling were improving(71%), and eight cases with scleral buckling surgery were enhanced ( 73%) . Statistical test showed the surgical treatment could significantly improve patients'eyesight, especially PPV with silicone oil, but the BCVA of patients with scleral buckling of external pressure in this study had no obvious significance according to the rank sum test. Compare with other surgery, pars plana vitrectomy( PPV ) combined silicone oil filling had more complications, such as high intraocular pressure and diplopia.
CONCLUSION: The therapy of super high myopia patients with rhegmatogenous retinal detachment need many years' clinical experience, surgical skill of clinician and according to the number, the shape and the site of the retinal holes and area of detached retina, they need to choose the right means of surgery, and timely deal with postoperative complications, in order to improve the patients' postoperative retina, reset rate and visual function.

Diabetic retinopathy(DR), one of the most common retinal vascular disease, is one of the causes of blindness for people over the age of 50.In the early stage of DR, microvascular cells are damaged, expand, start to leak, form micro hemangioma, then show occlusion, and non-perfusion area come into being, eventually form new blood vessels because of ischemia and hypoxia of retina.Illness develop into proliferative diabetic retinopathy(PDR).With the aggravation of the disease, PDR can cause the formation of fibrovascular membrane, the more serious fibrillation of epiretinal membrane, resulting in traction retinal detachment(tRD).Present studies suggest that aquaporins, the essential component of new blood vessels, including aquaporin 1 and aquaporin 4, play a significant pole in the development of diabetic retinopathy, causing the destruction of blood retinal barrier, inducing retinal edema, even macular edema, and participating in the formation of retinal angiogenesis.

Objective To analyse the diagnosis and treatment of testicular torsion. Methods The clinical data of 66 cases of testicular torsion were retrospectively analysed. Results Among the 66 cases,32(48.5%) paid the first medical visit within 10 h,and 24(36.4%)were confirmed diagnosis at the first visit.False negative results occurred with color Doppler flow imaging(CDFI),and 8 testicles were damaged due to the false negative diagnosis.Thirty-three patients without prophylactic contralateral orchidopexy were followed up for 6 months to 20 years,and one experienced recurrent torsion. Conclusion The testicular torsion must be considered when a sudden acute scrotum pain is occurred.Testicular damage is closely related to the torsion time,and delayed medical intervention contributes to the testicular damage.Highly suspected cases should be performed surgical exploration timely due to the false negative results with CDFI.Prophylactic contralateral orchidopexy is recommended.

The purpose of this investigation is to improve ethanol production and decrease acetate formation in Saccharomyces cerevisiae strain YS2-?adh2.The strain YS2-?adh2 with deleted alcohol dehydrogenase Ⅱ(adh2) gene was isolated in our lab with higher ethanol production than that of the strain YS2.The ace-taldehyde dehydrogenase Ⅵ(ald6) gene encoded a cytosolic acetaldehyde dehydrogenase,a key enzyme of the pyruvate dehydrogenase(PDH) bypass,transfers acetaldehyde to acetate.To disrupt ald6 gene of the strain YS2-?adh2,ald6 gene targeting cassettes were synthesized by long flanking homology PCR(LFH-PCR) and then were transformed into YS2-?adh2 mutants by LiAc/SS Carrier DNA/PEG method.Positive transformants were selected with G418 and further confirmed by PCR.Once correctly integrated into the genome,the selective marker was rescued by transforming the plasmid pSH65 into the positive transformants and inducing the Cre expression with a Cre/loxP-mediated marker removal procedure.We named the ald6 gene knocked-out strain as YS2-?adh2-?ald6 which has a 12.5% higher ethanol production and a 18% lower acetate formation compared to the strain YS2.
