Objective:To investigate the therapeutic role of topical, oral and combine of itraconazole treatment using a rabbit model of Aspergillus fumigatus keratitis. Methods: The epithelium was removed from the central cornea and the inoculum of Aspergillus fumigatus blastoconidia was placed on the corneal surface and covered with a contact lens. Forty-eight hours later the 32 rabbits were randomly divided into four groups. In topical group, rabbits were treated with topical itraconazole(1%,eight times daily); in oral group, rabbits received oral itraconazole (40 mg/kg,bid);in combine of group, rabbits were treated between topical itraconazole(1%,eight times daily) and oral itraconazole [40 mg/(kg?d)]. Untreated controls were also set. The eyes were examined and photographed with a slit-lamp 1,3,6, 10,15,20 and 25 days after inoculation, and an observer graded the corneas in a masked fashion. Corneal scraping, cultures were taken on days 3,6,15 and 25 for fungus growth. Results: At the beginning of treatment, with in 1 to 3 days, the slit-lamp scores did not differ among four groups. However, after days 6 the three treated groups had statistically significant lower scores compared to the untreated controls (P

ObjectiveTo investigate the hypersensitive C-reactive protein(hs-CRP),level in serum and the heart rate variability(HRV) in patients with dysthymic disorder,and explore the possible psychological and physiological mechanisms.MethodsPHI and short-term HRV were measured in 42 patients with dysthymic disorder( DD group),33 patients with major depressive disorder ( MD group)and 30 heathy controls( NC group),fasting blood samples were also analyzed with high-sensitivity C-reactive protein (hs-CRP).Results ( 1 ) DD group gained higher score in the somatization,anxiety,psychopathic deviate and hypomania than the MD group(P＜0.05 or P ＜ 0.01 ).(2)The standard deviation of differences between the consecutive RR intervals (SDNN),the percentage value of consecutive RR intervals that differ more than 50 ms(PNN50) and the high frequency band(HF) of DD group were lower significantly than MD and NC groups,the low frequency band(LF),and the ratio of LF to HF power(LF/HF) and hs-CRP level were higher than other two groups (P ＜ 0.05 or P＜0.01 ).(3)The somatization and anxiety were correlated with SDNN,the very low frequency band(VLF),LF and hs-CRP level ( r=-0.27,-0.29,r=0.38,0.33,r=0.41,0.31,r=0.34,0.23,P＜0.05 or P＜0.01).(4)The hs-CRP level in serum were correlated with SDNN,the root mean square of successive RR intervals (RMSSD),the standard deviation of differences between the consecutive RR intervals ( SDSD),VLF,LF,HF and LF/HF ( r =- 0.47,- 0.45,- 0.45,0.26,0.46,-0.51,0.10,P ＜ 0.05 or P ＜ 0.01 ).ConclusionThe patients with dysthymic disorder have significant somatization and anxiety,the personality character was mainly resulting in reducing HRV,which is related with the increasing serum hs-CRP level.

Objective To investigate the relationship of serum IL-6 levels with cognitive dysfunction among patients with obstructive sleep apnoea syndrome (OSAS).Methods Patients diagnosed with OSAS by polysomnography (PSG) received assessment of cognitive function with Montreal Congnitive Assessment (MoCA).According to the result of MoCA assessment,patients were divided into two groups,without cognitive dysfunction group (n =47) and with cognitive dysfunction group (n =55);30 health volunteers were used as control.Serum IL-6 levels were detected by enzyme-linked immunosorbent assay (ELISA) in three groups;according to the apnea hypopnea index (AHI),OSAS patients with cognitive dysfunction were divided into three groups,light group (n =15),moderate group (n =16),and severe group (n =24),and differences in MoCA scores and serum IL-6 levels were analyzed among three groups.The correlation of serum IL-6 levels and MoCA scores were analyzed in OSAS patients with cognitive dysfunction.Results Serum levels of IL-6 in OSAS patients with cognitive dysfunction [(197.3 ± 72.58) pg/ ml] were significantly increased than those without cognitive dysfunction [(155 ± 39.3)pg/ml] as well as health control [(87.39 ±33.44)pg/ml] (P ＜0.01).For OSAS patients with cognitive dysfunction,MoCA scores were decreased and the level of serum IL-6 was increased among patients with poor AHI grade,with statistically significant difference.Pearson correlation analysis showed serum IL-6 levels were significantly negatively correlated with MoCA scores among OSAS patients with cognitive dysfunction (r =-0.65,P ＜ 0.01).Conclusions Serum levels of IL-6 in OSAS patients with cognitive dysfunction were significandy increased and correlated with the cognitive dysfunction.OSAS patients with cognitive dysfunction experiencing sever AHI grade have more serious cognitive dysfunction and the higher serum levels of IL-6.

Objective: To study the effects of hyperbaric oxyge(HBO) in the treatment of periodontitis.Methods: 60 Guinea pigs were divided into 3 groups, 20 animals each group: ①Experimental periodontitis was induced by silk suture and feeding with the food containing 100 g/L of sugar and then exposed to 0.25 MPa of HBO for 60 min once a day when periodontitis established; ② the other 20 animals were simillary treated to group ① but not exposed to HBO; ③ another 20 animals were used as controls. HBO treatment was conducted for 2 weeks. Samples of periodontal tissues were obtained 0,4,8 and 10 weeks after treatment and prepared for histopathological study and electron microscopic observation.Results: In the treated group there were fewer macrophages in gingiva and periodontal ligment, more blood vessles, less absorption of alveolar bone, more osteoblasts and more osteogenesis in the bone. There were fewer metochodria and rough endo reticulum in plasmacytes, macrophages and osteoclasts; and more in fibroblasts, endothelial cells of blood vessles and osteoblasts. Conclusion: HBO may improve blood supply, inhibit macrophage and bone absorption.

Cerebral ischemia-induced inflammatory cascade reaction may aggravate nerve tissue damage and destroy blood-braln barrier, and angiogenesis after ischemia can improve nerve function. Inhibiting inflammatory response after stroke, promoting angiogenesis and protecting blood-braln may reduce nerve tissue damage and promote recovery of neurological function. Monocyte chemotactic protein 1-induced protein inhibits inflammatory signaling pathways through degradating proinflammatory cytokine mRNA. Its unique biological characteristics also suggest that it has the potential protective effect in cerebral ischemia. This article focuses on the roles of monocyte chemotactic protein 1-induced protein in cerebral ischemia.

OBJECTIVE:To explore the effects of Xuesaitong injection on related indexes of patients with acute ST segment el-evation myocardial infarction(STEMI)before percutaneous coronary intervention(PCI). METHODS:112 STEMI patients under-went PCI were analyzed retrospectively and divided into control group (48 cases) and observation group (64 cases) according to different treatment methods. Control group was given Clopidogrel sulfate tablets 300 mg and Aspirin enteric-coated tablets 300 mg orally before PCI;given conventional treatment according to patients'condition after surgery. Observation group additionally re-ceived intravenous push of Xuesaitong injection 8 mL before surgery,and Xuesaitong injection 8 mL added into Sodium chloride 250 mL intravenously,once a day after surgery,on the basis of control group. Treatment course of 2 groups lasted for 14 d. TIMI level,MPG level,the serum levels of cTnT,CKMB were observed in 2 groups before surgery,24 h after surgery;serum level of PTX-3,hs-CRP were observed before surgery,one week after surgery;LVEF,LVEDD,serum level of BNP were observed before surgery and one month after surgery;the occurrence of ADR was observed to. RESULTS:Before surgery,there was no statistical significance in TIMI level,MPG level,the serum levels of cTnT,CKMB,PTX-3 and hs-CRP,LVEF,LVEDD,serum level of BNP between 2 groups (P>0.05). 24 h after surgery,TIMI level and MPG level of 2 groups were significantly higher than be-fore,and the observation group was significantly higher than the control group;the serum levels of cTnT and CKMB in 2 groups were significantly lower than before,and the observation group was significantly lower than the control group,with statistical sig-nificance(P<0.05). One week after surgery,the serum levels of PTX-3 and hs-CRP in 2 groups were significantly lower than be-fore surgery,and the observation group was significantly lower than the control group,with statistical significance(P<0.05). One month after surgery,the level of LVEF in 2 groups were significantly higher than before surgery,and the observation group was significantly higher than the control group;LVEDD and se-rum level of BNP in 2 groups were significantly lower than be-fore surgery,and the observation group was significantly lower than the control group,with statistical significance (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Based on convention-al treatment,Xuesaitong injection can effectively improve myocardial blood supply before PCI,decrease the level of inflammatory factor,relieve myocardial injury,improve cardiac function without increasing the incidence of ADR.
