Objective To investigate clinical and pathological characteristics of acquired digital fibrokeratoma (ADF).Methods Clinical data were collected from 12 patients with ADF,and their clinical manifestations,histopathological features,treatment and prognosis were analyzed retrospectively.Results The mean age at onset of ADF was 39.75 ± 17.69 years (range,17-64.5 years),and the average disease duration was 4.83 ± 5.77 years (range,0.5-20 years).The ratio of male to female was 1.4:1.Most skin.lesions were polymorphic,and mainly involved fingers,toes and nail grooves.Sometimes non-extremity sites are also involved.Histopathological examination of skin lesions showed epidermal hyperkeratosis,acanthosis and broadened dendroid rete ridges.The dermis consisted of mature collagen bundles,fibroblasts and a large number of dilated capillaries.The characteristic manifestation was that most collagen bundles were vertical to the epidermis.Conclusions ADF,a rare benign fibrous tumor with unknown etiology,usually occurs in adults as a solitary lesion on fingers or toes,sometimes in non-extremity sites.Surgery and laser therapy are common treatments for ADF with low recurrence rate.

Objective To study the effect of specific immunotherapy (SIT) with purified humulus pollen allergens for asthma patients. Methods The humulus pollen allergens were purified partially by gelatin filtration. A double-blinded study was carried out. Eight-six patients with seasonal humulus pollen allergic asthma were divided randomly into two groups: observation group (group A) and control group (group B), which were administered SIT with purified or crude humulus pollen allergens, respectively, before the allergic season for half a year. The clinical effect and side effects were observed. The laboratory observation norms included T lymphocyte subpopulation, the wheals’diameter of IT, the average index of HBDT and the specific IgE before and after SIT . Results The general effect of SIT with purified allergens in group A was 90.7% (39/43), and that with crude allergens in group B was 79.1% (34/43) (P

AIM To evaluate the effect of METHODS 2 month-old mice were fed routinelycistanche desertica polysacchrides(CDP) on the ni- for 11 mounths to establish the model of naturallytric oxids(NO) ,superoxide dismutase(SOD) in se- aging mice. The cistanche desertica polysacchridesrum and apoptosis of lung cell in aging mice. 25, 50, 100 mg ?kg~' were administrated respec- lively to the mice po. then investigated the concentration of NO, SOD and the morphological changes of apoptosis by fluoromicroscope. RESULTS Aging could induce the lung cell apoptosis, decrease the level of SOD, and increase the level of NO as well. The cistanche desertica polysacchrides signif- icantly ameliorated the lung cell apoptosis; decreased the level of NO, improved the activity of SOD. CONCLUSION Cistanche desertica polysac-chrides have ameliorating and postponing effects on the regressive changes in the lung of aging mice.

Aim To evaluate the pharmacological effects of sodi um ferulate on asthmatic guinea pigs. Methods Guinea pigs were sensit ized by ovalbumin. Two weeks later,ment of Sodium ferulate were injected every d ay five minutes before inhale, the guinea pigs were killed 7 days later. Granul ocyte-macrophage colony-stimulating factor (GM-CSF), interleukin-4 (IL-4), interleukin-5(IL-5), Eosinophil cationic protein (ECP) in serum were measured by Enzyme-linked immunosorbent assay(ELISA) and fluoroimmunoassay method, the e osinophils (EOSs) were counted and the phosphodiesterase (PDE) in the bronchoalv eolar lavage fluid(BALF) were determined by inverse high-performance liquid chr omatography (HPLC) method. Result After treatment with sodium f erulate for one week at the dose of 25,50,100 mg?kg -1 respectively, th e GM-CSF, IL-4, IL-5 contents were inhibited as compared with the untreated g roup in a dose dependent manner.The count of eosinophil was decreased.The activi ty of PDE of cell in BALF and the level of ECP were decreased.Conclusion Sodium ferulate attenuates the GM-CSF, IL-4, IL-5 in serum and eosi nophils and the activity of PDE and ECP and has protective effect in asthmatic g uinea pig.

Objective To study the mechanism of hypoxia inducing factor-1α(HIF-1α)pathway in establishment of hypoxia inducing low endometrial receptivity.Methods RL95-2 cell lines.the ideal model of study ER,were cultured in hypoxia condition induced by CoCl2,and the expression of mRNA and protein of HIF-1α and tumor necrosis factor like weak inducer of apoptosis(TWEAK)were measured by reverse transcription-PCR and western blot. The apoptosis rate was analyzed by flow eytometry.Then the mechanism confirmed by comparing the two factors in endometrium and the ultra-appearance of inflammatory reaction and apoptosis between recurrent spontaneous abortion women and control women.Results (1)On difierent time point(0,12,24,48 hour),mRNA expression of HIF-1α were 0.272±0.010,0.354±0.020,0.591±0.020.0.890±0.020,while the expression of TWEAK were 0.104±0.010,0.510±0.020,1.021±0. 020, 1. 237 +0. 040, respectively, the expression level between 12, 24, 48 and 0 hour all showed significant differences (P＜0. 05 ). (2) Protein expression of HIF-1α were 0. 853 +0. 010, 0. 931 ±0. 030,1. 124±0.010, 1.317±0.0 20 respectively, while was 0.042±0.010, 0.091 ±0.010, 0. 131±0.020,0. 205 ±0. 030 in TWEAK expression, the different level were statistically significant ( P＜0. 05 ). ( 3 )With longer culture under hypoxia, the cell apoptosis rate increased obviously. The apoptosis rate of each time point were ( 3.2±1.4 ) %, ( 16. 2 ±3.2 ) %, ( 26. 3±3.5 ) %, ( 31.8±3.5 )%, the differences between 12, 24, 48 and 0 hour had significance (P ＜0. 05). (4) The positive rate of HIF-1α stained in epithelium cells and stroma cells of test group were 32. 3%, 8.4% and 16. 7%, 7. 3% in control group. The positive rate of TWEAK were 28. 3%, 3.9% in recurrent spontaneous abortion group and 11.6%, 2. 7% in control group ( P ＜0. 05 ). The ultra-appearance of inflammatory cell infiltrated and apoptosis were obvious in test group. Conclusions Cell inflammation reaction and apoptosis induced by HIF-1α pathway may participate the mechanism of hypoxia inducing low endometrial receptivity. HIF-1α might become a novel target for improving poor endometrial receptivity.

Objectives To understand the status of wild feces distribution and pollution in schistosomiasis endemic areas in Yunnan Province. Methods According to the distribution of Oncomelania hupensis snails and characteristics of human and ani-mal activities in recent five years 6 schistosomiasis endemic villages in Weishan Nanjian and Midu counties 2 villages each county were selected as the investigated areas and more than 4 hm2 area with snails around each village were investigated for the types and densities of wild feces. The schistosome infested feces was detected with the hatching method. Results Totally 63 hm2 were investigated and 420 wild feces were found in all kinds of environments. The densities of wild feces were 0.066 7 piles/100 m2 and the densities of wild feces of the road and the hillside were the highest 0.098 7 piles/100 m2 and 0.088 0 piles/100 m2 respectively . Totally 260 fresh wild feces were collected including the feces of human being cattle horse dog sheep and pig and the feces of cattle and dog was the most 37.38%and 30.71% respectively . No schistosome positive feces was found. Conclusions There are a lot of wild feces in snail areas in Yunnan Province and the risk of schistosomiasis transmission is still high. Therefore we should strengthen the banning grazing measures and the investigation of dogs.
