A patient with basidiobolomycosis is reported,the clinical course described,the ultra- structural and histologic changes observed,and mycologic examination was made.The results indicated that:(1)In the course of using corticosteroids,because the inflammatory reaction was suppressed par- tially,the clinical manifestation was relatively relieved.In the loci the pathogenic fungi still grew well, and focal dissemination was observed;(2) In the course of using itraconazole,the drug exerted fungistatic and fungicidal action through the destruction of cell membranes of fungi.Meanwhile,itra- conazole also exerted a synergistic action with the defense function of the human body,resulting in an enhanced therapeutic effects.The strong acute inflammatory reaction was triggered by the destroyed fungi caused by itraconazole.Then the fungi were cleared,the lesions were absorbed and repaired.Sur- gical intervention may be helpful to remove abscesses and fibrous nodules formed in the clinical course, so as to shorten the course of treatment.

OBJECTIVE:To study improvement effect of modified mahuang chanyi decoction on allergic rhinitis(AR)model guinea pigs and its mechanism. METHODS:32 guinea pigs were randomly divided into normal group (0.9% Sodium chloride in-jection),model group (0.9% Sodium chloride injection),experimental [Modified mahuang chanyi decoction,5.18 g (medicinal materials)/kg] group and control [Fluticasone propionate nasal spray,50 μg/(guinea pig·d)] group. Except for normal group,other groups received ovalbumin 30 mg and calmogastrin 30 mg intraperitoneally to induce AR model. Except for control group,other groups were given relevant medicine intragastrically,twice a day for consecutive 15 d. Nasal symptoms of guinea pigs were ob-served and recorded,and then analyzed and scored. The protein expression of nasal mucosa SHP-1 was detected by immunohisto-chemistry,the serum contents of IL-4 and IFN-γ were determined by enzyme-linked immunosorbent assay. RESULTS:Compared with normal group,model group suffered from AR symptom,and nasal symptoms score was increased;and the protein expression of nasal mucosa SHP-1 and the serum content of IL-4 increased,while the content of IFN-γ decreased(P<0.05). Compared with model group,AR symptom of experimental group and control group were improved;nasal symptoms score,the protein expression of nasal mucosa SHP-1 and the serum content of IL-4 decreased while the content of IFN-γ increased(P<0.05). CONCLUSIONS:Modified mahuang chanyi decoction shows certain improvement effect on AR,and its mechanism is associated the decrease of IL-4 content and the increase of IFN-γcontent in serum.

Background Studies showed that macophenolic acid (MPA)down-regulates and inhibits the expression and secretion of tissue growth factor and inflammatory factor,and further impacts the proliferation and inflammation process.Pterygium is an inflammatory and proliferative lesion.Whether MPA has an inhibitory effect on pterygium is unclear.Objective This study was to investigate the antifibrotic effects of macophenolic acid on pterygium fibroblasts(PFBs) in vitro and discuss its mechanism.Methods Pterygium tissue was obtained from pterygium patient during the surgery.PFBs were cultured using explants and identified with vimentin immunohistochemisty.0,0.125,0.250,0.500,1.000 μmol/L MPA were added into the culture medium,respectively,and the cells were cultured in the medium without MPA as the control group.MTT colorimetry was used to find the optimization effective concentration of MPA and evaluate their inhibitory effect on PFBs,and BrdU fluorescence staining was used to assess the growth statue of PFBs.Expressions of nuclear factor-κB(NF-κB),p65 and inhibitor of NF-κB-α(IκB-α) in the cells were detected by Western blot.Results The cells was spindle in shape 3 days after cultured and showed the vortex and radial arrangement with the positive response to vimentin.With the increase of MPA,the proliferative value of PFBs (A560)showed gradually decline,with a significant difference among the five groups (F =42.874,P＜0.01).In addition,the proliferative value of PFBs (A560) significantly lowed as the prolong of MPA active time(F=26.038,P＜0.01).BrdU fluorescence staining showed a significant decrease of DNA synthesis of PFBs with the elevation of MPA dose among the five groups(F=175.279,P＜0.05),and the A560of PFBs DNA synthesis in different concentrations of MPA groups was lower than that of the control group (all at P＜0.05).No apoptotic and necrotic cell was found after MPA action by DAPI staining.The expression level of p65 in the PFBs was 0.886±0.072 and 1.542±0.124 in the MPA group and the control group,indicating a declined value in the MPA group(P＜0.05).However,the expression value of IκB-α in the cytoplasm PFBs was significantly higher in the MPA group compared with the control group(2.141 ±0.305 vs.1.559±0.267) (P＜0.05).Conclusions MPA has an inhibitory effect on the growth of PFBs,which probably is related to the arresting of NF-κB pathway.

Objective To explore the effect of high voltage alternating electric field therapy on fracture healing in rats. Methods An animal model of cortical bone defect was successfully established in the unilateral proximal tibia of 41 rats.They were then randomized into an experimental group (21 rats) and a control group (20 rats).The animals in the experimentsl group were given high voltage alternating electric field therapy for 30 minutes daily,while those in the control group only had sham exposure to the high voltage alternating electric field therapy.Rats in each group were sacrificed at days 7,14,21 and 28 post-operation.After blood collection,the operated tibias of the rats were resected with muscle and other soft tissue removed.Bone mineral density (BMD) of the callus at the fracture point was measured using dual energy X-ray absorptiometry (DEXA).The calluses were then cut down and fixed,decalcificated and sliced for histological observation.At the same time serum osteocalcin ( OC ) and bone alkaline phosphatase (RAP) were also detected by ABC-ELISA. Results The BMD examination showed that callus BMD in the experimental group was significantly higher than in the control group at days 14 and 28.Serum OC and RAP in the experimental group were also higher at days 14 day 21,and OC was still significantly higher in the experimental group at day 28.Histological examination showed that in the early stages of bone healing hematoma absorption and organization appeared earlier in the experimental group than in the control group,with remarkable osteoblast and chondroblast proliferation.While at the later stage,bone trabeculas connection and mineralization also appeared earlier in the experimental group than in the control group. Conclusions High voltage alternating electric field therapy may promote fracture healing by accelerating hematoma absorption and organization,elevating osteoblast proliferation and differentiation as well as promoting extracellular matrix secretion and mineralization.The underlying therapeutic mechanism might be related to the increased expression of OC and RAP caused by exposure to the high voltage alternating electric field.
