Moyamoya disease (MMD) is a chronic and progressive cerebrovascular disease which is characterized by the bilateral internal carotid artery ends and (or) stenosis or occlusion of anterior cerebral artery and middle cerebral artery initial segments,compensatory proliferation of small blood vessels in the skull base and formation of abnormal vascular network.Its etiology and pathogenesis remains unclear.The present studies speculate that MMD may be a polygenic disease,inflammation,immune response,abnormal cytokine secretion,endothelial progenitor cell change and nitric oxide level change are associated with the occurrence and development of MMD.This article reviews the advances in research on the genetics and pathophysiological mechanism of MMD.

Objective To investigate the clinical efficacy of conventional treatment combined with flupentixol and melitracen in patients with reflux esophagitis (RE).Methods From June 2012 to March 2015, a total of 182 patients were selected as study subjects from newly diagnosed RE patients.The anxiety and depression scores were evaluated according to Hamilton anxiety scale (HAMA) and Hamilton depression scale (HAMD).And then patients were divided into HAMA and HAMD negative conventional treatment group and combined treatment group, HAMA and HAMD positive conventional treatment group and combined treatment group.Rabeprazole and mosapride were administrated in conventional treatment group.For patients in combined treatment group, on the base of conventional treatment flupentixol and melitracen were added.The treatment course was eight weeks.The degree of anxiety and depression, RE symptoms and mucosal healing under gastroscope were evaluated before and after treatment.Adverse drug reaction was observed.Chi square test or t test was performed for statistical analysis.Results Eight weeks after treatment, the scores of HAMA and HAMD in HAMA and HAMD positive combined treatment group were 7.930 ±3.832 and 9.630 ± 3.650, which were both lower than those of conventional treatment group (11.660 ± 4.108 and 12.170 ± 4.459), and the differences were statistically significant (t=3.683 and 2.233;both P＜0.05).The symptom scores of heartburn, regurgitation, chest pain of HAMA and HAMD positive combined treatment group were 0.700±0.591,0.780± 0.629 and 0.720±0.621, respectively, which were lower than those of conventional treatment group (1.280 ± 0.502, 1.370 ± 0.610 and 1.040 ± 0.842), and the differences were statistically significant (t =5.133, 4.413 and 2.114, all P＜0.05).There were no statistical significance in symptoms scores between HAMA and HAMD negative combined treatment group and conventional treatment group (all P＞0.05).After treatment, the mucosal healing rate of HAMA and HAMD positive combined treatment group was 91.3％ (42/46), which was higher than that of conventional treatment group (71.7 ％, 33/46), and the difference was statistically significant (x2 =5.845, P =0.016).The incidence of adverse events of HAMA and HAMD negative combined treatment group was 4.8％ (2/42), and that of HAMA and HAMD positive combined treatment group was 2.2％(1/46).Conclusions The conventional treatment combined with flupentixol and melitracen in RE patients accompanied with anxiety and depression was remarkable and safe.RE patients without obvious anxiety or depression, preventive use of antianxiety and antidepressant medicine can not improve the efficacy.

Objective To investigate general and clinicopathological characteristics of male breast cancer and analyze the factors affecting the outcomes of the patients.Methods Fifty-nine male breast cancer patients treated at Cancer Hospital of Zhengzhou University from January 2002 to December 2011 were included into the study.The clinicopathologic features and 5-year survival rate were retrospectively analyzed.The clinicopathologieal characteristics were investigated by univariate analysis to evaluate the impact of these factors on patient survival.Results The median age at diagnosis was 64 years old in these patients.The positive rate of ER/PR was 74.6 ％ (44/59).The patients were followed up for 9-123 months.The 5-year survival rate was 61％.Patients in stages Ⅰ and Ⅱ had better overall survival than those in stages Ⅲ and Ⅳ.Conclusion The male breast cancer patient has special clinical characteristics.TNM stage is a significant predictor of the overall survival.

Objective To optimize the volatile oil extraction and inclusion process of Wenweiyang capsules. Methods An orthogonal test was adopted in this study. The extraction technology was optimized for the yield of volatile oil regarding the amount of water loaded, grain size of medicinal material, and decoction time as factors. The inclusion technology was optimized for the inclusion yield and volatile oil inclusion rate using the ratio ofβ-CD:oil, amount of water and grinding time as factors. Results The optimized extraction parameters were as follows:breaking medicinal material through 10 mesh screen, adding 6 fold volume of water and extracting for 5 h. The optimized inclusion progress was grinding at theβ-CD:oil ratio of 81, loading equivalent amount of water and grinding for 30 minutes. The average yield of volatile oil is 1. 72%, the average inclusion rate is 93. 01% and the average volatile oil inclusion rate is 74. 82%. Conclusion The extraction and inclusion technology is simple, reliable, which can effectively retain the volatile oil and provide evidence for the preparation of Wenweiyang capsules.

Objective To explore the value of urine formaldehyde test in the diagnosis of Alzheimer's disease (AD),and the influential factors of urine formaldehyde level in AD patients.Methods A total of 52 AD patients and 53 cognitively normal controls were recruited in a cohort study.All subjects were no less than 65 years old,and those with acute infection,or dysfunction in heart,liver or kidneys were excluded.The impact of age,gender,onset age,MMSE score,NPI score,MTA score,and ApoE ε4 gene on urine formaldehyde of AD patients were analyzed by multiple regression analysis.Results Urine formaldehyde level of AD group was statistically higher than that of cognitively normal control group ((13.27±4.16)μmol/L vs (10.76±4.47)μmol/L,t=2.99,P=0.15).Urine formaldehyde of AD patients was statistically negatively correlated with MMSE score (β=-0.35,P=0.03) and MTA score (β=-0.38,P=0.02).The impact of onset age,neuropsychiatric disorders and ApoE ε4 gene on urine formaldehyde of AD patients was not statistically significant(all P>0.05).Conclusion Urine formaldehyde level is worthwhile to be explored as a marker in AD diagnosis and severity assessment.

Objective To investigate histopathological and ultrastructural differences between melasma tissues and normal skin tissues around pigmented nevus. Methods Eight patients with melasma and 16 patients with facial pigmented nevus were included in this study. Two millimeter punch biopsies were taken from melasma lesions and adjacent normal skin of facial pigmented nevus. Biopsy specimens were then subjected to hematoxylin?eosin (HE) staining, Fonton?Masson staining, Verhoeff?van Gieson staining, and immunohistochemical staining with monoclonal antibodies HMB45 and NKI/beteb. Transmission electron microscopy was used to observe the tissue specimens. Semi?quantitative analysis was performed under a light microscope, and quantitative analysis by using a computerized image analysis system. Results Histopathological study revealed increased number of melanin granules mainly in the basal and prickle cell layers, sometimes in the dermis, in melasma tissues compared with normal skin tissues. Melanocytes were only observed in the epidermis of melasma tissues. Compared with normal skin tissues, melasma tissues showed no significant difference in the quantity of melanocytes, but a significant increase in the volume, staining intensity and dendrite number of melanocytes. In all of the 8 patients with melasma, mild to moderate lymphocytic infiltration was observed in the superficial dermis and around capillaries, with moderate telangiectasis in the superficial dermis. Electron microscopy revealed that there were more melanosomes in melanocytes and keratinocytes, and melanocyte dendrites extended into the dermis in melasma tissues. Conclusions Among the 8 patients, there were only two types of melasma, i.e., epidermal melasma and mixed melasma, and no dermal melasma was found. Inflammation and telangiectasis may induce or aggravate melasma.

OBJECTIVETo dicuss the application and therapeutic effect of middle-forearm flap based on perforator of ulnar artery for electrical burn wound on the wrist.

METHODSFrom Oct. 2009 to Oct. 2012, 10 cases of electrical burn wounds on the wrist were treated. A line from radialis medial epicondyle of humerus to the interior radialis pisiform bone was connected as flap axis. At the midpoint of the line, Doppler flow imaging meter was used to detect the emerging point of perforator vessel. The flap was designed and harvested. The flap was transferred reversely, with superficial vein retaining which was anastomosed with vein at recipient sites in 3 cases. The wounds in the donor sites were closed directly in 2 cases, and with skin graft in 8 cases.

RESULTSAll the 10 flaps survived completely. 7 cases without vein anastomosis underwent obvious flap edema during 2-4 days postoperatively, which resovled 1 week later. Sub-flap tissue necrosis and infection happened in 2 cases, which healed after dressing and drainage. Patients were followed up for 3-36 months with satisfactory results.

CONCLUSIONSThe middle-forearm flap based on perforator of ulnar artery has a stable and reliable blood supply. It offers a new choice for the electric burn wound on the wrist, especially at the ulnar side.
