0.05)]. Conclusion The elevated serum HA is linked to a potential marker in kidney transplantation.

Risk management is derived from industry.In recent years,risk management is introduced by many medical laboratories their process management abroad.However,the concept of risk management is still very new for laboratories in China.Therefore,the establishment of the project for risk detection,classification,correction,prevention and supervision could help medical laboratories improve their service quality.

The laboratory accreditation plan is an effective way to realize the standardization of medical laboratories.The test method validation is required by ISO 15189 guideline and CAP checklists.However,after CBC analyzers and coagulation analyzers are repaired,no solution for the validation is put forward.

Eccrine spiradenoma usually occurs as solitary tender nodules. However, it rarely occurs as multifocal localized tumors or has zosteriform distribution. We report the case of a 32-year-old woman with a 20-year history of itchy lesions on the left side of the back and forearm with a zosteriform distribution. Before disease onset, almost no patients have inducing factors, but our patient received an injection beforehand; however, whether this was coincidental or causative remains unknown. The lesions became very itchy after perspiration or eating spicy food, which has never been reported. A literature search revealed 22 cases of multiple segmental eccrine spiradenoma; we summarized the clinical characteristic in order to aid diagnosis and treatment selection.

AIM: To determine the optimal protocol and condition in which macaca irus mesenchymal stem cells (MSCs) are induced to differentiate into neuron-like cells by cryptotanshinone in vitro. METHODS: MSCs from macaca irus bone marrow were generated in vitro and induced with cryptotanshinone. The morphological changes of MSCs were evaluated by microscope. The positive percentages of neurofilament (NF), neuron specific enolase (NSE) and glial fibrillary acidic protein (GFAP) expression were measured by immunocytochemistry with ABC staining. RESULTS: The result showed that MSCs were positive for CD29, CD44, CD105, CD166, and negative for CD34, CD71, CD80 and CD86. After induced with cryptotanshinone, MSCs began to display neuronal morphologies, such as contracted multipolar cell body and formed extensive networks. The percentages of positive NSE, NF expression were 68.3%?3.5%, 70.3%?1.5%, respectively. CONCLUSION: Macaca irus MSCs could be induced to differentiate into neuron-like cells in vitro by cryptotanshinone and might be applied in cell transplantation and gene therapy in nervous system disorders.

Objective There have been a few reports on chronically recurrent and generalized superficial mycosis caused by trichophyton rubrum.This article was to investigate the cause, diagnosis and therapy of the mycosis. Methods 5 patients with chron-ically recurrent and generalized superficial mycosis caused by trichophyton rubrum were collected from June 2012 to June 2014 in our hospital.Bacterioscopic examination and cultivation were made on skin lesions of the patients.A typical patient who had 7-year course of desease with toenails seriously infected and widespread skin eruption was selected for histopathology examination on skin lesions, mi-crobiology and molecular biology study on 4 bacterial strains isolated from skin lesions in different parts, and in vitro chemosensitivity assay for drug selection.PCR (rDNA ITS sequence analysis) was performed for diagnosis and early treatment. Results Microscopic examintion on skin lesions demonstrated numerous septate, branched hyphae.Cultivation and molecular biology study identified tricho-phyton rubrum.The strain was identified as trichophyton rubrum by ITS sequence analysis and the isolated strains from different lesions were the same fungal species.Histopathology examination revealed slight hyperplasia of squamous epithelium , epidermal hyperkeratini-zation and the upper dermis presented a sparse perivascular lymphocytic infiltrate.The PAS-stain confirmed the presence of few hyphae in the horny layer.The pathogen of this case was trichophyton rubrum. A combination therapy with systemic itraconazole and topically applied terbinafine hydrochloride cream was successful.A follow-up examina-tion one year later showed no recurrence of symptoms. Conclusion The isolation and identification of pathogen is the key to the diagnosis of chronically recurrent and generalized superficial mycosis, with ad-ditional attention to all or none toenail infection.The therapy should not focus simply on the tinea corporis, while comprehensive treatment combined with chemosensitivity assay is preferred.

Objective The article was to observe the clinical efficacy of the application of terbinafine and mizolastine in com -bined treatment of chronic eczema ( CE) with dermatophytes infection , so as to define the etiology role of dermatophytes in allergic dis-eases. Methods All subjects were randomly divided into experiment group and control group .The experiment group was treated with the combination of terbinafine and mizolastine , while the control group took mizolastine orally alone .EASI grading , recovery rate and effective rate were evaluated at 2, 3 week after the treatment and EASI grading and recurrence rate were evaluated at 4 weeks after the treatment. Results 79 patients had finished the experiment .Significant difference was found in the effective rates between two groups at 3 weeks after treatment (P<0.05).At 4 weeks after the treatment, EASI value and recurrence rate in experiment group were obviously lower than those in control group (P<0.05). Conclusion Good therapeutic effect has been achieved through the ap-plication of terbinafine and mizolastine in combined treatment of CE with dermatophytes infection , which implies dermatophytes plays an important role in the etiology of CE .

Objective: To study the influence of conditioned medium of rat brain microvascular endothelial cells on the activity of cortical neurons and the protective effect of Tong Luo Jiu Nao Injection.Methods: We collected the conditioned media from 4 different cultured endothelial cell groups,which were normal endothelial cells,the normal ones and treated with Tong Luo Jiu Nao Injection,the injured ones damaged by simulated cerebral ischemia,as well as the injured ones and treated with Tong Luo Jiu Nao Injection,respectively(N-CM,NT-CM,I-CM,IT-CM).Then,the conditioned medium was added into the cultures of the normal neurons and the damage ones which are injured by simulated cerebral ischemia as well,respectively.The effect of each type of conditioned medium on the activities of neurons was determined through the measurement of MTT and the transduction rate of LDH.Results:(1) N-CM has no obvious effect on the normal neurons,but does show some protective effect on the injured ones by increasing its activity significantly;(2) I-CM could decrease the activity of the normal neurons as well as aggravate the damage on the injured ones,while this injury effect can be reversed remarkably by IT-CM.Conclusion: The paracrine secretion of the brain microvascular endothelial cells might be one of the vital mechanisms in cerebral ischemic injury,indicating that the brain microvascular endothelial cells could be the therapeutic targets of Chinese medicine,which are not able to permeate through the Blood-Brain Barrier.

Objective: To observe the protective effects of Gastrodine on the cultivated rat brain microvessel endothelial cells damage by mimic cerebral ischemia.Methods: The endothelial cells activity,survival rate,the change in NO content,and the effects of Gastrodine were observed in the cultivated rat brain microvessel endothelial cells(BMEC) damaged by mimic cerebral ischemia.Results: The activity and survival rate of BMEC in the ischemia groups are obviously lower than that in the normal groups;compared with the normal groups,the activity,survival rate and NO content of BMEC in the Gastrodin groups have the increasing tendency;comparing to the ischemia groups,the activity of BMEC in the Gastrodin groups obviously increasing(P

Objective To study the diagnosis and treatment of lower thoracic ossification of ligamentum flavum(OLF)combined with lumbar spinal stenosis.Methods Retrospective analysis was carried out on 11 cases of lower thoracic OLF combined with lumbar spinal stenosis.There were 4 males and 7 females,with an average age of 56 years,and the average course of disease was 42 months.From March 2007 to March 2009,all patients undergone thoracic and lumbar laminectomy and posterior-lateral fusion in one stage.Oswestry disability index(ODI)was used to assess the neurological functional status,visual analogue score(VAS)was recorded to assess low back pain,and Cobb's angle was used to evaluate the change of thoracolumbar kyphosis.Results Operation time was 200 to 450 min,with an average of 273 min;blood loss was 600 to 1800 ml,averaged 954 ml.There were two cases of cerebrospinal fluid leakage.Eleven cases were followed up for 13 to 36 months,with an average of 23.7 months,Preoperative VAS,Oswestry score and Cobb's angle was 7.91±0.83,66.36%±10.91%,5.91°±0.83° respectively.Postoperative VAS,ODI and Cobb's angle at the final follow-up was 2.18±1.90,25.45%±12.19% and 12.18°±3.06° respectively.VAS and ODI were significantly decreased after operation.The Cobb's angle was significant increased after operation,resulting in pathologic thoracolumbar kyphosis.Conclusion The clinical features of lower thoracic OLF are complicated,which may result in misdiagnosis if the thoracic OLF is accompanied with lumbar spinal stenosis.It is an optimal selection for lower thoracic OLF combined with lumbar spinal stenosis to resect lower thoracic and lumbar lamina in one stage.For females with osteoporosis,additional internal fixation in lower thoracic spine is necessary.
