Objective To evaluate the safety and efficacy of Voriconazole on invasive fungal infections in very elderly patients.Methods Clinical data of 24 very elderly patients with invasive fungal infections who had sought treatment at the Department of Geriatrics of our hospital from April 2013 to April 2014 were retrospectively investigated.The classifications and quantities of fungi,accompanying symptoms,adverse reactions,blood tests,and liver and kidney function indicators were recorded and analyzed before and after treatment.Results Each of the 24 cases was found to have been infected with one or more of 17 fungal strains belonging to the genus of Candida.The rate of complete fungal elimination after treatment was 70％ (12/17).Of the 24 cases,5 achieved a full recovery(20.8 ％),10 (41.7 ％) had significant improvement,5 (20.8 ％) had some improvement,and 4 cases(16.7％)showed no therapeutic benefits,with a total effectiveness rate of 62.5 ％.There was no significant difference in liver and kidney function before and after treatment(P＞0.05).A transient increase in serum creatinine occurred in 1 case and defective vision in another patient during Voriconazole treatment.Conclusions The incidence of invasive fungal infections is high in very elderly patients,with Candida as the main pathogen.Voriconazole is effective in treating invasive fungal infections in very elderly patients,and close monitoring of liver and kidney function is required during voriconazole treatment.

Objective To investigate the influence of prepubertal exposure to estradiol benzoate (EB)in the male reproductive system of the rats and the natural process of tissue repair,and to clarify the possible mechanism of the reproductive toxicity of exogenous estrogen.Methods Ninety 2 1-day-old male Wistar rats were randomly divided into 2 experimental groups (low dose of EB group and high dose of EB group,n=30)and control group (n=30). The rats in the experimental groups were injected with EB dissolved in peanut oil at 15(low dose of EB group)and 15 000μg·kg-1 (high dose of EB group)respectively,the rats in control group received equal vehicle injection only,once every other day for two weeks from postnatal day(PND)21 to 34.All of them were normally fed after the drug usage was stopped.The testes were harvested at the stages of PND 60 and PND 125(n=15 at each stage).The serum levels testosterone of (T),follicle-stimulating hormone(FSH),luteinizing hormone(LH),prolactin (PRL)and estradiol(E2)of the rats in various groups were detected with radioimmunology method and the weights of the rats in various groups were recorded;the histological changes of the testes tissue were observed with light microscope.Results On PND60,compared with control group,the T levels in low dose of EB group and high dose of EB group were decreased(P<0.05 or P<0.01);the FSH,LH and E2 levels were increased (P<0.05 or P<0.01),and the PRL levels had no change(P>0.05);the weights of testes were decreased(P<0.01);the histological changes of the testes of the rats in experimental groups included seminiferous tubules maldevelopment, decreased cell number of seminiferous epithelia.Compared with low dose of EB group,the T and FSH levels in high dose of EB group were decreased (P<0.05 or P<0.01),the E2 and LH levels were increased(P<0.01),the PRL level had no change (P>0.05 ), and the weight of testes was decreased (P<0.01 );the diameters of seminiferous tubules were smaller,there was no sperm in high dose of EB group while there were a few sperms in low dose of EB group.On PND125,compared with control group,the T,FSH and PRL levels in low dose of EB group and high dose of EB group were decreased(P<0.01),the E2 levels were increased (P<0.01);the LH level in low dose of EB group was increased(P<0.05),the LH level in high dose of EB group was decreased(P<0.01), and the weights of testes in high dose of EB group were decreased(P<0.01);the diameters of seminiferous tubules and the cell number of seminiferous epithelia were increased but not apparent change.Compared with low dose of EB group,the T,LH levels in high dose of EB group were decreased (P<0.01),the E2 and FSH levels were increased(P<0.01),the PRL level had no change(P>0.05),and the weight of testes was decreased(P<0.01);there was still no sperm in high dose of EB group, the number of sperms was increased in low dose of EB group, but it was still lower than that in control group.Conclusion EB is harmful to the reproductive system and can change the normal serum sex hormone levels,even induces the irreversible injury.

Objective To summarize the clinical features,treatment and prognosis of bullous systemic lupus erythematosus (BSLE).Methods Clinical data were collected from 6 cases of BSLE between May 2009 and September 2015,and were analyzed retrospectively.Results Among the 6 patients,2 were male and 4 were female.The mean age of onset was 34 years.All the 6 patients presented with tense blisters and bullae arising on an erythematous base or normal skin,which were arranged in an annular pattern in 3 patients.The SLE Disease Activity Index (SLEDAI) score was ＞ 4 in all the 6 patients.Histopathological examination showed subepidermal blisters or fissures in all the patients.Direct immunofluorescence (DIF) revealed continuous linear deposition of immunoglobulin G (IgG),IgM and IgA in all the patients,linear deposition of C3 in 4 patients,and linear deposition of Clq in 2 patients at the basement membrane zone (BMZ).All the 6 patients were treated with oral glucocorticoids and hydroxychloroquine,and 2 patients were additionally treated with cyclophosphamide.During the follow-up period,adverse reactions to different extents were observed in the 6 patients.Conclusions BSLE mainly occurs in young and middle-aged people.Histopathologically,subepidermal blisters or fissures can be observed with linear deposition of IgG,IgM,IgA,or C3 along the basement membrane zone on DIF.

Objective:To investigate the change of expression of miR-7 in activated CD4+ T cells in vitro, and preliminary explore its possible significance. Methods: CD4+CD62L+T cells was purified from splenocytes of FVB mice by magnetic cell sorting system (MACS). After stimulation with anti-CD3/CD28 antibody,the relative expression of miR-7 was examined by Real-time PCR, and the expression level of CD69 molecular was analyzed by FACS. Furthermore,the relative expression of miR-7 in CD4+T cells was detected at different time points during stimulation. With the treatment of ERK inhibitor PD98059,change of miR-7 expression was de-termined by Real-time PCR. Meanwhile, the proliferation of CD4+T cells was examined by CCK-8 assay and the expression level of CD69 and CD62L molecular were analyzed by FACS. Finally,the expression of cytokines IL-6,IL-10,and IFN-γ were determined by Real-time PCR. Results:Compared with control group,the relative expression of miR-7 was increased significantly after stimulation with anti-CD3/CD28 antibody,as well as expression level of CD69 molecular was augmented(P<0. 05). In contrasted with 0 h and 24 h,the expression of miR-7 was significantly increased after 48 h and 72 h during stimulation(P<0. 05). Furthermore,the relative expression of miR-7 was significantly declined in CD4+T cells in ERK inhibitor PD98059 treatment group. Finally, the expression level of CD69 molecular,as well as cytokines IL-6, IL-10 and IFN-γ, were also decreased significantly ( P<0. 05 ) . Conclusion: The relative expression of miR-7 was significantly increased in activated CD4+T cells,closely related to ERK pathway,which provided an important foundation for successive research work on exploring the functional role of miR-7 in the CD4+T cells.

ObjectiveTo evaluate the efficacy of sphenopalatine ganglion stimulation with acupuncture for moderate-to-severe perennial allergic rhinitis.MethodsA total of 50 patients were recruited into a sphenopalatine ganglion stimulation group and a routine acupuncture group according to order of presentation, with 25 in each group. The sphenopalatine ganglion stimulation group received sphenopalatine ganglion stimulation with filiform needle, 1-2 sessions/week for 4 weeks. The routine acupuncture group received traditional acupuncture, withyingxiang(LI 20),yintang(GV29),fengchi(GB20),fengfu(GB16),zusanli(ST36) as the maln points, andyingxiang(LI 20),yintang(GV29),fengchi(GB20),fengfu(GB16),zusanli(ST36) as the adjunct points, 1-2 points from both the maln and adjunct points in each session, 2 sessions/week for 4 weeks. The nasal symptom score (2004 version), the total nasal symptom score (TNSS) and the total non-nasal symptom score (TNNSS) were used to evaluate symptom improvement. The Rhinoconjunctivitis Quality of Life Questionnalre (RQLQ) was used to assess the patients’ quality of life. The time to symptom alleviation, duration of symptom alleviation in every session and the recurrence duration during 1 month after the treatment were compared between the two groups.Results After the treatment, the score of the nasal symptom score (99.74 ± 31.89vs.196.83 ± 31.22;t=-4.912,P=0.001), TNSS (33.63 ± 12.37vs.71.82 ± 19.21;t=-3.463,P=0.003), TNNSS (33.63 ± 12.37vs.71.82 ± 19.21,t=-3.463,P=0.003) in the sphenopalatine ganglion stimulation were significant lower than those in the routine acupuncture group. Compared with the routine acupuncture group, the time to symptom alleviation was significant shorter (13.85 ± 4.21 minvs.45.63 ± 7.87 min;t=-1.763,P=0.008), while the duration of symptom alleviation was significant longer (37.92 ± 9.94 hvs.3.35 ± 1.23 h;t=7.637,P<0.01) after each session in the sphenopalatine ganglion stimulation group. Four weeks after the treatment, RQLQ score in the sphenopalatine ganglion stimulation group was significant lower than that in the routine acupuncture group (8.48 ± 3.71vs.37.68 ± 12.46;F=-7.312,P<0.01). The recurrence duration during 1 month after the treatment in the sphenopalatine ganglion stimulation group was significant longer than that in the routine acupuncture group (4.12 ± 2.15 dvs.23.53 ± 4.63 d;t=-8.879,P=0.003).ConclusionSphenopalatine Ganglion stimulation is superior to routine acupuncture in treatment of patients with moderate-to-severe perennial allergic rhinitis.

Objective To explore the effects of miR -30c over -expression on early cardiac development of zebrafish.Methods The single -cell -stage zebrafish embryos were micro -injected with 3 different concentrations of miR -30c mimics in order to model the miR -30c over -expressed animal.Besides,the effects of miR -30c overex-pression on cardiac development were investigated.The mortality rate and the heart rate were assessed.Beside,the gross morphology and heart morphology of the zebrafish were observed.Moreover,the molecular mechanisms underlying miR -30c function in zebrafish cardiac development was explored,and in -situ hybridization was performed.Results Compared with the wild -type embryos,the mortality rate of zebrafish was increased with the rising miR -30c concen-tration.Furthermore,when the miR -30c mimic concentration was up to 8 μmol/L,the mortality rate reached 80% at 96 h post -fertilization.Simultaneously,the heart rate,which was viewed as an important index to cardiac function,was decreased.Moreover,the pericardial edema was getting worse over time with increasing concentration of overexpression. Then,the cardiac specific gene expression on the zebrafish embryos by whole -mount in situ hybridization was ex-plored.The area of the cardiac chamber was extended and the heart tube looping was negatively affected.Besides,the expression of atrioventricular canal marker genes was absent in zebrafish embryos from miR -30c over -expression groups.Conclusion miR -30c can impact the early cardiac development of zebrafish.

Objective To evaluate the effects of rapamycin combined with rosiglitazone on lung injury in septic rats.Methods One hundred and twenty healthy male Wistar rats were randomly divided into 5 groups (n =6 each):sham operation group (group S); cecum ligation and punture (CLP) group; rapamycin group (group RPM) ; rosiglitazone group (group RGZ) ; rapamycin plus rosiglitazone group (group RPM + RGZ).The rats were anesthetized with intraperitoneal 10% chloral hydrate 100 mg/kg.Sepsis was induced by CLP in groups CLP,RPM,RGZ and RPM + RGZ.At 30 min before CLP,rapamycin 0.4 mg/kg was injected subcutaneously in RPM group,rosiglitazone 0.3 mg/kg was injected via the femoral vein in RGZ group,and rapamycin 0.4 mg/kg was injected subcutaneously and rosiglitazone 0.3 mg/kg was injected via the femoral vein in group RPM + RGZ.While the equal volume of normal saline was given instead in CLP group.Six rats were sacrificed at 2,6,24 and 48 h after CLP in each group,and lungs were removed and cut into sections which were stained with haematoxylin and eosin and examined under microscope.The pathological changes of lungs were scored.The myeloperoxidase (MPO) activity and signal transducer and activator of transcription 3 (STAT3)-DNA binding activity in lung tissues were measured.Results Compared with group S,the pathological scores,MPO activity and STAT3-DNA binding activity were significantly increased in groups CLP,RPM,RGZ,RPM + RGZ (P ＜ 0.05).The pathological scores,MPO activity and STAT3-DNA binding activity were significantly lower in groups RPM,RGZ and RPM +RGZ than in group CLP,and in group RPM + RGZ than in groups RPM and RGZ (P ＜ 0.05).Conclusion Rapamycin combined with rosiglitazone offers additional benefit to attenuating lung injury induced by sepsis over rapamycin or rosiglitazone alone,and inhibition of activation of STAT3 pathway is involved in the mechanism.

Objective Sarcopenia and metabolic syndrome share similar pathophysiological mechanisms. The aim of this study was to investigate the prevalence of sarcopenia among health examination population, and to analyze the relationship between sar-copenia and blood pressure, blood glucose, uric acid and lipids. Methods Physical examination data of 1191 healthy persons in the medical examination center of the hospital from Mar 2011 to Jun 2011 were collected. The weight, skeletal muscle, body fat, body mass index ( BMI) , waist circumference,body fat percentage, waist-hip ratio and visceral fat area were analyzed by human body compositionanalyzer and the prevalence of sarcopenia was observed. At the same time, triglyceride (TG), total cholesterol (TC), high density lipo-protein-cholesterol ( HDL-C ) , low density lipoprotein-cholesterol ( LDL-C) , uric acid and fasting blood glucose were also detected. Results The prevalence rate of sarcopenia of the subjects was 5.21%, and the highest incidence was found in ≥60 years group( 11.11%) . The prevalence rates of overweight and obesity were 33.8% and 10.2%, respectively. The prevalence of sarcopenia is grad-ually higher along with increasing BMI. The prevalence rates of sarcopenia of overweight and obesity subjects were 5.47% and 26.23%, respectively. Compared with the normal control group, the level of weight[(66.34±11.75)kg vs (76.71±12.84)kg ], BMI[(23.37± 3.13) vs (28.05±3.66)], body fat percentage[(25.33±6.06)% vs (36.76±4.47)%], waist circumference[(83.19±9.56)cm vs (95.45±13.74)cm] and visceral fat area[(88.96±29.74)cm2 vs (136.91±25.56)cm2] were higher in the sarcopenia group (P<0.05). Compared with the normal control group, the incidence of systolic blood pressure[(125.59±30.04)mmHg vs (139.39±19.79) mmHg], diastolic blood pressure[(75.82±11.95)mmHg vs (82.34±10.96)mmHg ] TG[(1.56±1.12)mmol/L vs (1.98±1.72)mmol/L] and uric acid[(313.75±83.07)mmol/L vs (335.55±96.07)mmol/L] were higher in the sarcopenia group (P<0.05). Compared with the normal subjects, the detectable rates of abnormal diastolic blood pressure, fasting blood glucose, uric acid, and LDL-C were increased in the sarcopenia, obesity and sarcopenia combined with obesity subjects (P<0.05). The odds ratio of abnormal systolic blood pressure, diastolic blood pressure, uric acid, and LDL-C increased in the sarcopenia, obesity and sarcopenia combined with obe-sity subjects using logistic regression analyses after correction of gender and age. Conclusion The sarcopenia may have some con-nection with metabolic risk factors. Early detection of sarcopenia can help to distinguish people predisposed to metabolic syndrome, and it has important significance for prevention of chronic disease.
