To observe the effect of autologous stem cell transplantation in diabetic retinopathy.
●METHODS:Totally 58 cases (116 eyes) who underwent autologous stem cell transplantation were confirmed as no diabetic retinopathy (18 eyes), mild non-proliferative diabetic retinopathy (NPDR) (41 eyes), mid-level NPDR (51 eyes); severe NPDR (6 eyes) by ophthalmoscope directly or indirectly and fluorescence fundus angiography (FFA ). Follow - up was 6 - 12mo, the changes of retinopathy were observed.
●RESULTS: The total effective rate of vision and retinopathy was 84. 4%, 76. 7%. The results of severe NPDR was statistically worse than the other groups ( P <0. 05).
●CONCLUSlON: The stable blood glucose level and improved pancreatic function after autologous stem cell transplantation might be helpful in diabetic retinopathy, the long effects need to be researched further.

Prostate cancer, bladder cancer, and rectal cancer are common malignancies in the male pelvis. The incidence rate of erectile dysfunction (ED) following radical prostatectomy, cystectomy or rectal cancer surgery is about 25% - 100%. The main cause of post-surgery ED is mainly attributed to injury of neurovascular bundles, which may lead to reduced oxygenation in and fibrosis of the penile tissue. Early penile rehabilitation after surgery can improve or restore the erectile function of the patients. This article focuses on penile rehabilitation after radical pelvic surgery.

Objective To investigate the pathogenesis of age-related cortex and nuclear cataract.Methods The levels of transforming growth factor-?_2 (TGF-?_2)mRNA,proliferating cell nuclear antigen (PCNA),ratio of Bcl-2/Bax,fibronection (FN),vimentin and the density of lens epithelial cells (LECs) were measured and compared among age-related nuclear cataract,cortex cataract and normal LECs.Results The ratio of TGF-?_2 mRNA expression/?-actin expression,the levels of PCNA protein,Bax and Bcl-2 in age-related nuclear cataract(0.16?0.02,16.01,15.97, 16.97)and in cortex cataract (0.27?0.01,1.98,16.93,1.44) were significantly different from those in normal LECs(0.15+0.02,2.43,16.84,6.12),all P

Objective To analyze the correlations between pediatric intersive cave unit (PICU) nurses′job satisfaction and their perception of job characteristics. Method One hundred and thirty-six PICU nurses from a women and children′s hospital of Guangzhou participated in the study and the job diagnostic survey (JDS) and Minnesota satisfaction questionnaire short-form (MSQ20) were used to investigate the relationship between the job characteristics and job satisfaction. Results The average score on general satisfaction was (3.57 ± 0.41). The dimensions like skill variety, task integrity, feedback from job and feedback from others, had a significant positive impact on general satisfaction (all P<0.05). Conclusion Nurses generally have a relatively middle level of job satisfaction and measures should be taken to improve their job satisfaction as well as the quality of nursing.

Xanthine oxidase (XOD), catalyzing purine metabolism, is the key enzyme in uric acid (UA) biosynthesis, and becomes an important target for hyperuricemia treatment. The inhibition on XOD plays an important role in the treatment of hyperuricemia-related diseases, such as gout, as well as oxidative stress-induced tissue injury. Here, studies on the natural products with XOD inhibition are reviewed.

Objective]To prove that Fujian Province is also a natural focus of Pagumogonimus veocularis(Pv).[Methods]The adult worms were obtained from a cat fed with Pv metacercariae.[Results]Pv were found in Jianou,Fujian Province.All 1 873 Semisulcospira libertina showed negative.The positive rate of Tricula fujianensis and Erhaia jianouenensis were 0.10%(1/695) and 0.25%(5/2 038), respectively. The main crab host was S.fujianensis.Ps alone and mixed infection with Pv were found in the Sinopotamon ,the infection rates were 36.8%(43/117)and 20.5%(24/117), respectively. The numbers of the metacercariae were 806 and 40, respectively. A cat was infected with 12 metacercariae of Pv , eggs were found in the stool 56 days after infection,and 6 worms were found in the lungs 68 days after infection. [Conclusion]Fujian is one of the natural focus of Pv, cat is the adequate host. The fluke was identified as Pv according to the characteristics of the metacercariae.

This paper is aimed to microscopic identification of traditional Chinese medicines (TCMs) using an in situ imaging method. In this study, two kinds of Zingiberaceae seeds, Amomi Rotundus Fructus and Alpiniae Katsumadai Semen, were investigated by synchrotron radiation in-line X-ray phase-contrast computed tomography (IXPCT) imaging method. The results showed that the microstructures of these Zingiberaceae seeds could be clearly obtained from the virtual slices information in different observing angles. It proves that IXPCT is an effective imaging method, which can provide the imaging information for the microscopic identification of the intact TCMs in situ and non-destructively.

Objective To investigate the association between PARK16 gene polymorphism and Parkinson's disease(PD)susceptibility in Chinese Han population.and to analyze its single-nucleotide polymorphism(SNP)genotypes,frequencies and odds ratios(OR)of different genotypes.Methods The association between two SNP loci in PARK16 gene(Rs947211,Rs823128)and PD susceptibility was investigated by TaqMan quantitative polymerase chain reaction(PCR)in 226 PD patients and 362 healthy controls.Allele and genotype frequencies were calculated by the Chi-square test,and the clinical data were also analyzed.Results Three genotypes of Rs947211(GG,AG and AA)account for 34.1%(77/226),46.0%(104/226),19.9%(45/226)in the PD group,and 23.8%(86/362),53.0%(192/362),23.2%(84/362)in the control group,respectively.There was significant difference between two groups (P<0.05).Setting the GG genotype as the reference,OR values of AG and AA genotype were 0.57(95%CI0.38-0.85,P=0.006)and 0.55(95%CI 0.34-0.85,P=0.015),while the OR value for exposure to the A allele(AA+AG)was 0.56(95%CI0.38-0.82,P=0.003).Genotypes of Iate-onset PD were also significantly different from the controls(OR valne of AG=0.46,95%CI 0.27-0.78,P=0.004:OR value of AA=0.35.95%CI 0.18-0.68,P=0.002).And there was no diffefence in clinical features among the 3 genotypes. The frequency of Rs823128, another locus, in PD group was not significantly different from the control group( AA genotype as the reference, OR value of AG was 1. 12, 95% CI 0. 75-1.68, P = 0.568; OR value of GG was 0.99, 95% CI 0.35-2.76, P = 0.994). Conclusion Polymorphism of PARK 16 locus Rs947211 is associated with PD patients in Chinese Han population.

In order to improve the interfacial bonding strength of hydroxyapatite/polyurethane implanted material and dispersion of hydroxyapatite in the polyurethane matrix, we in the present study synthesized nano-hydroxyapatite/polyurethane composites by in situ polymerization. We then characterized and analyzed the fracture morphology, thermal stability, glass transition temperature and mechanical properties. We seeded MG63 cells on composites to evaluate the cytocompatibility of the composites. In situ polymerization could improve the interfacial bonding strength, ameliorate dispersion of hydroxyapatite in the properties of the composites. After adding 20 wt% hydroxyapatite into the polyurethane, the thermal stability was improved and the glass transition temperatures were increased. The tensile strength and maximum elongation were 6.83 MPa and 861.17%, respectively. Compared with those of pure polyurethane the tensile strength and maximum elongation increased by 236.45% and 143.30%, respectively. The composites were helpful for cell adhesion and proliferation in cultivation.

Objective To explore disinfection efficacy of anerdian using swab and spray disinfection methods.Methods Hands of 30 subjects were randomly divided into the swab group and the spray group.The samples of before and after disinfection in each group were collected separately and observed their disinfection effect.Results The number of bacteria showed no significant difference between the two groups.The passing rate of disinfection reached 100％.The time of disinfection in the spray group was (2.58±0.32)s,significantly less than that in the swab group,(12.26±1.48)s,however,the drying time in the spray group was (42.37±1.79)s,significant longer than that in the swab group,(26.24±1.46)s.A subject hand disinfection used 0.5ml 0.2％ anerdian in the spray group,and 0.75ml 0.2％ anerdian and two cotton buds was used in the swab group.Conclusions There is identical disinfection efficacy between spray and swab methods.Spray disinfection method has short operating time,less use of disinfectant without using cotton buds,it is able to replace swab disinfection and will play an important role to reduce medical waste and health care costs.
