Diabetic retinopathy(DR)is a neurovascular unit lesion caused by diabetes mellitus,the incidence of which has increased significantly with the increase of the diabetic population.Therefore,it is important to use a reasonable animal model to explore the pathogenesis and therapeutic targets of DR.The db/db mouse is a relatively mature animal model of spontaneous type 2 diabetes and is therefore widely used in early prevention and treatment studies of type 2 DR.This paper describes the progress of db/db mouse model in exploring the pathogenesis of DR and the pharmacological research of Chinese and Western medicine,in order to provide a certain reference for the research of DR and drug development.

Clinical data of a 33-year-old rheumatoid arthritis patient accompanied with pregnancy and lactation-associated osteoporosis(PLO) was retrospectively reviewed.The patient had two pregnancies within three years,and bone pain occurred during lactation of the second pregnancy after 2 months of delivery.Dual-energy X-ray (DEXA) showed decreased bone density,while thoracolumbar spine and pelvic X-ray film suggested osteoporosis.Her rheumatoid arthritis was stable and previous treatment did not include glucocorticoids.Other causes of metabolic bone diseases were excluded and the diagnosis of PLO was confirmed.The breastfeeding was stopped;calcium,active vitamin D,alendronate sodium were administrated,and the treatment was effective.Domestic and international literature from January 2000 to January 2019 was searched and no cases of PLO accompanied with rheumatoid arthritis were reported.There were only 100 cases of PLO retrieved in the literature,including 19 cases of PLO in China reported by four articles.It is suggested that PLO should be considered in RA patients presenting with arthragia during the lactation,in addition to relapse of disease.Awareness of PLO should be increased in physicians,especially rheumatologists,and anti-osteoporosis therapy is effective in patients with PLO.

Objective: To observe the long-term efficacy and safety of autologous hematopoietic stem cell transplantation (AHSCT) for systemic sclerosis (SSc) patients. Methods: Between May 2007 and June 2009,4 patients with SSc were enrolled in the study. Peripheral blood stem cells were mobilized with cyclopho-sphamide (CTX) followed by granulocyte colony stimulating factor (G-CSF). Conditioning was performed with i.v. cyclophosphamide 50 mg·kg^-1·d^-1 for 4 days. The results of the modified Rodnan skin score (mRSS), thoracic high-resolution computer tomography and pulmonary function were collected after transplantation. Results: There was an improvement in mRSS, lung function and HRCT in the six months after AHSCT. Within six month to one year after transplantation, one patient had sustained and two patients recurred. After active treatments two patients were improved again. During the follow-up of 8.7 (4.1-9.8) years, three patients were stable and one patient died. Infection and hepatic function injury were the major complications. There was not transplant-related mortality. Conclusion AHSCT with CTX as a pre-conditioning regimen is safe and effective for SSc. The efficacy for patients with short course, rapid progress and edema is significant. However, long-term efficacy is poor, and long-term maintenance treatment is needed.

Objectives To understand the social support levels among breast cancer patients in Yunnan, as well as to explore the factors associated with social support. Methods According to the unified inclusion and exclusion criteria,121 breast cancer in-patients with chemotherapy were interviewed with structured questionnaire. Social demographic characteristics, Xiao's Social Support Rating Scale,General Self-Efficacy Scale,clinical and experimental data were collected. SPSS version19.0 was used to analyze the frequency and the correlation between social support and influential variables were analyzed by using the chi-square test and non-parametric test. Results The levels of social support in total, objective social support, subjective social support and utilization degree for breast cancer patients were (49.43 ±5.69), (13.35 ±2.51), (27.59 ±3.78), (8.50 ±1.98) respectively. Marriage status and self-efficacy were associated with social support level significantly. The influencing factors such as age, education level, marital status, occupation, income, place of residence, religion, medical expenses payment type, self-efficacy were included in the univariate analysis. However, only marital status and self efficacy were positively correlated with social support (p<0.05) . Conclusions The breast cancer patients in Yunnan have a higher social support level overall. Having-marriage status and higher self-efficacy have a positive influence on breast cancer in patients' social support level.

Objective To explore the effect of continuous nursing on patients with spinal cord injury neurogenic bladder who were discharged from the hospital after spercutaneous minimal invasive bladder fistulization. Methods Totally 43 patients with spinal cord injury and underwent percutaneous minimal invasive bladder fistulization were divided into the control group and the observation group by random digital table method, with 23 cases in each group. Patients in the control group received routine nursing, while patients in the observation group received continuous nursing based on the routine nursing. The level of colostomy adaptation and the incidence of complications related to catheter in two groups were observed. Results Six months after nursing intervention, the score of colostomy adaptation level in the observation group was significantly superior to that in the control group (P<0.01); in the intervention group, the incidence of urinary tract infection, skin infection around the stoma;the incidence of complications such as catheter slippage, catheter blockage, catheter breakage, were all lower than that in the control group ( P<0. 05 ) . Conclusions The continuous nursing intervention can improve the level of colostomy adaptation and reduce the incidence of catheter related complications.

ObjectiveTo investigate the predisposing factors and pathogenic fungal species of Malassezia folliculitis in different geographical areas and body sites.MethodsTotally,241 patients diagnosed with Malassezia folliculitis were asked to complete a questionnaire.The content of hair follicles was obtained and subjected to fungal smear and culture examination.Fungal species were identified according to morphological,physiological and biochemical features.Results Of the 241 patients with Malassezia folliculitis,204 (84.65％) were positive for smear examination.A total of 259 specimens were collected from these patients,and fungal culture grew 213(82.24％) strains,of which,209 belonged to Malassezia species,4(1.54％) to Candida species.Among the 209 Malassezia strains,186 were activated and subjected to species identification which resulted in 6 species,including M.furfur (111 strains,59.68％ ),M.sloofiae (43 strains,23.12％ ),M.sympodialis (17 strains,9.14％),M.globosa (9 strains,4.84％),M.pachydermatis (4 strains,2.15％),and M.obtuse(2 strains,1.08％ ).Of the pathogenic fungi of Malassezia folliculitis,M.furfur predominated in the chest,back,abdomen,face and neck,M.sloofiae in the upper limbs,shoulders and vertex,M.globosa in the lower limbs.There were obvious differences in the distribution of pathogenic fungal species at different body sites in a same host,and M.furfur with M.sloofiae or M.sympodialis appeared to be the most common pathogens.ConclusionsIn this study,6 Malassezia species are identified in patients with Malassezia folliculitis in Nantong and Nanjing area,M.furfur and M.sloofiae appear to be the dominant pathogens.
