Growth patterns of trichome and contaminative bacteria in Spirulina sp. liquid culture were observed, and it was found that the number of neutral and alkalophilic bacteria was always 105~106 times of that of Spirulina sp. trichome. It would be very difficult to get real pure Spirulina sp. strain by classical methods of dilution plate, capillary and single trichome selecting methods. A great deal of contaminative bacteria was washed out by two pretreatment processes. Low speed centrifugation was designed to wash the strains which usually deposit at bottom, and filtration method was designed to treat the strains usually floating at surface. Sandwich plate and dilution plate were designed for the purification of the mobile strains and non-mobile strains, respectively. A lot of strains were purified by the above processes and pure single trichome formed pure colonies on plates.

Objective To investigate the influence of retinoic acid receptor (RAR-α,RAR-β and RAR-γ)-mediated all-trans retinoic acid (ATRA) on renal tissue cell proliferation and apoptosis in rats with diabetic nephropathy,and to analysze the possible mechanism. Methods Male SD rats were randomly divided into normal control group (group N,n=10) and diabetic model group (n=20).Diabetes was induced by streptozotocin(STZ) injection.After successful modeling,the model rats were randomly divided into diabetes group (group D,n=10) and ATRA treatment group (group T,n=10).Rats in group T received ATRA 10 mg·kg-1·d-1 by gavage from the 2nd day of successful modeling for 8 or 12 weeks,meanwhile group N and group D received same volume distilled water.In each group,5 rats were sacrificed respectively at the 8th week or the 12th week,then biochemical markers were measured and kidney pathology was examined.Apoptosis index(AI)of renal tissue cells of each group was tested by TUNEL.The expressions of RAR-α,RAR-β and RAR-γ in renal tissues were tested using indirect immunofluorescence.The expressions of type Ⅰ collagen and laminin as proliferation indicators,along with Smac and caspase-3 as the correlated factors of apoptosis in renal tissue of each group were tested by immunohistochemistry staining.The mRNA expressions of Smac and caspase-3 were tested using real-time fluorescence quantitative PCR. Results Compared with group N,24 h urine protein,serum creatinine,blood urea nitrogen,ratio of kidney weight/body weight increased significantly (P<0.05,respectively) in group D,and further increased with observation time.Compared with the group D,24 h urine protein and ratio of kidney weight/body weight decreased in group T (P<0.05,respectively).Compared with group D,the group T presented minor pathological changes.TUNEL assay indicated that compared with group N,the group D showed an obvious increase in renal cell apoptosis in time-dependent manner,and the group T showed a decrease compared with the group D (P<0.01,respectively).Compared with group N,the expression of RAR-α and RAR-β positive cells number in group D were decreased (P<0.01,respectively).Compared with group D,the expression of RAR-α and BAR-β positive cells number in group T increased (P<0.01,respectively).Renal tissues of each group did not show expressions of RAR-γ.After 12 weeks,compared with group N,expressions of type-Ⅰ collagen,laminin,Smac and caspase-3 protein in the glomerular mesangial area and basement membrane of renal tissues in group D increased significantly (P<0.01,respectively),and enhanced with time.Compared with the group D,expressions of type Ⅰ collagen,laminin,Smac and caspase-3 protein in group T decreased (P<0.01,respectively).Compared with the group N,group D had an obvious increase in the mRNA expressions of Smac and caspase-3,and a significantly decrease in group T (P<0.01,respectively). Conclusions ATRA may prevent the cell proliferation and apoptosis in diabetic renal tissue through its receptor-mediated pathway,and may protect rats against diabetic nephropathy.

Objective To study the morphological characteristics of eyes of female Uygur youth for providing the relevant data for eye aesthetic plastic surgery.Methods Compared with 150 cases of Han youth in the same school,the somatological survey was carried out in 150 female Uighur college students with the morphological characteristics of the eyes and good facial harmony.SPSS 17.0 was used for statistical analysis of the measured data in groups divided according to different race.Results 59.3% (89/150) of the Uighur young women had prominent brow ridges tall nose and superior orbit cave,18.7% (28/150) of them were similar to the Han type of eye,and 22.0% (33/150) in between.The rate of epicanthus in Uighur women was 28.0% (42/150),which was significantly lower than the Han nationality women 62.7% (94/150).Double eyelid incidence was 96.7% (145/150),which was significantly higher than that of Chinese Han women 67.3% (101/150).There was a no statistically significant difference between them in palpebral fissure length inner canthic diameter and outer canthic diameter (P>0.05),but a statistically significant difference was found in the height of palpebral fissure,the width of double eyelid and the distance between the eyebrow eyelid (P<0.05).Conclusions The Uighur women's eye morphology has dual characteristics of Caucasoid and Mongoloid.The data have great significance and value in guiding the eye's cosmetic plastic surgery.

Objective To explore the clinical characteristics,therapy reactions and prognosis of the elderly patients with idiopathic thrombocytopenic purpura(ITP). Methods A total of 43elderly ITP patients(age≥60 years old)including 16 men and 27 women were reviewed and further followed up for 1 month to 15 years. Results Until June 2007,35 elderly ITP patients survived,platelet counts were sustained(30-50)×109/L in 7 cases,but no significant bleeding was found.Thirty-six patients had adrenocorticosteroid therapy first, 25 patients were sensitive to adrenocorticosteroid therapy,4 patients underwent splenectomy,and 3 patients achieved a normal platelet count. Immunosuppressive agents(vinscristine,cyclophosphamide, azathioprine and Cyclosporin A)treatments were held in 5 6 case-times,Cyclosporin A and azathioprine were more effective than vinscristine and cyclophosphamide.The refractory rate was 13.9%.One patient progressed to monoclonal gammopathy of unknown significance and 1 to lymphoma.Eight patients died.1 patient died of brain bleeding after trauma,3 patients died of malignant neoplasm,4 patients died of heart failure induced by infection. Conclusions The clinical features of elderly ITP patients are atypical.the mortal bleeding in them was rare,treatment strategy should be individualized tO each elderly patient.

AIM:To study testicular pathological change and its pathogenesis. METHODS:Testicular structure of alloxan induced diabetic rats was observed under light microscopy (LM)and transmission electron microscopy(TEM). Activity of superoxide dismutase(SOD),glutathione peroxidase(GSH-PX),nitric oxide synthase(NOS)and content of malondialdehyde (MDA),nitric oxide(NO) were detected biochemically in testicular homogenate. RESULTS:It is manifestated as atrophy of seminiferous tubule and germinal arrest under LM and expansion of mitochondria and smooth endoplasmic reticulum, cytoplasmic inclusion of sertoli cell under TEM.Activity of SOD, GSH-PX decreased while activity of NOS, content of MDA, NO increased in diabetic rats compared with control one. CONCLUSION:Disturbance of spermatogenesis and damage of sertoli cell are the main morphological change of diabetic testis, lipid peroxidation and NO may be involved in it.
