Objective To analyze the relative factors for the prognosis in elderly patients with stroke,and provide theoretical basis for improving prognosis.Methods 188 elderly patients with stroke were treated in our department from Jan.2011 to Nov.2013,and clinical data was analyzed.The prognosis and relative risk factors for stroke were statistically analyzed.Results 99 cases had good prognosis,89 cases had poor prognosis,and the recovery rate were 52.7％ (99/188) and 47.3％ (89/188) respectively.The age was older in group of good prognosis than in group of poor proghosis (t=1.7930,P＜0.05).Univariate analysis showed that the age,position of cerebral infarction,size of lesions,hypertension,diabetes,drinking and smoking were associated with the prognosis of stroke (t=1.7930,x2 =8.6473,15.046,13.1334,4.1536,5.7004,5.9043,respectively,all P＜0.05),while the prognosis was not associated with gender,a family history of stroke,hyperlipidemia and heart disease.Multivariate logistic regression analyses revealed the prognosis of stroke was related with risk factors of age (OR=1.072),size of the lesion (OR=3.481),hypertension (OR=2.034),diabetes (OR=1.631) and smoking (OR=3.144).Conclusions It is beneficial to the prognosis of patients with stroke to stop bad habits and to treat hypertension and diabetes actively.

Objective To observe the impact of Aspergillus fumigatus conidia on the early apoptosis of alveolar epithelial cells.Methods A549 cells was first stimulated with tumor necrosis factor-α(TNF-α)or staurosporine (STS)to induce cell apoptosis,and then co-cultured with Aspergillus fumigatus conidia of three different concentrations (5 × 10 5 ,5 × 10 6 ,5 × 10 7 )simultaneously.The changes of the apoptosis rate of A549 cells were detected by flow cytometry.Results The early apoptosis of A549 cells was increased markedly after stimulated with TNF-α ([14.94 ± 0.82 ]% vs [3.26 ± 0.74]%,χ2 =9.18,P <0.05)and STS ([18.10±1 .00]% vs [3.26±0.74]%,χ2 =12.32,P <0.05). When Aspergillus fumigatus conidia of different concentrations were added,the apoptosis rate was decreased (χ2 =31 .23,P <0.05 ).The early apoptosis of A549 cells was negatively correlated with the concentration of Aspergillus fumigatus conidia (rTNF = - 0.92,r STS = - 0.94,both P < 0.05 ). Conclusion Aspergillus fumigatus conidia inhibits the early apoptosis of A549 cells induced by TNF-αor STS and the inhibit effect increases with the concentration of Aspergillus fumigatus conidia.

Abstract: Objective　To compare the different effects of body mass index (BMI) and lean body mass index (LBMI) on the risk of all-cause death among elderly Chinese individuals. For the more scientific, accurate and convenient measurement of the elderly physique, analysis and evaluation of the health risk factors of the elderly in China. Methods　This study is based on follow-up data from 2014 to 2018, involving 5 990 participants who met the inclusion criteria in the Chinese Longitudinal Healthy Longevity Survey. Participants were grouped according to their BMI and LBMI, and both univariate and multivariate Cox proportional hazard models were established to compare the effects of BMI and LBMI on the risk of death in the elderly. According to gender, age, activities of daily living, and comorbidities, subgroup analysis was conducted to study the influence of LBMI in different subgroups. Results　The study population predominantly comprised females (52.9%, 3 167/5 990), with an average age of (84.7 ± 10.1) years, and most participants lived in rural areas (55.1%, 3 298/5 990). A majority were non-smokers (82.7%, 4 952/5 990) and non-drinkers (84.3%, 5 050/5 990). The prevalence of hypertension was 32.8% (1 966/ 5 990), diabetes 5.6% (334/5 990), and heart disease 12.9% (774/5 990). In the analysis of the impact of BMI on all-cause death in the elderly, univariate analysis showed that an increase in BMI was associated with a reduced risk of mortality. After adjusted by multiple factors (age, gender, living environment, marital status, average arterial pressure, number of children, smoking, drinking, hypertension, diabetes, heart disease, cerebrovascular disease, tumor, ADL/IADL, number of complications), compared to the normal group, the emaciated group (BMI<18.5 kg/m2) had the highest risk of death (HR=1.15,95%CI: 1.01-1.30); the overweight group (24.0 kg/m2≤BMI<28.0 kg/m2) had a lower risk of death (HR=0.78, 95%CI: 0.67-0.91). In the analysis of the impact of LBMI on the risk of death in the elderly, compared to moderate LBMI, lower LBMI was associated with a higher risk of death. Multivariate analysis showed that compared with moderate LBMI, a decrease in LBMI increased the risk of death, whereas an increase in LBMI did not show statistically significant differences in mortality risk in the elderly. Conclusion　In measuring fitness and quality of life in the elderly, LBMI has better representativeness and practical value.

The deubiquitinating enzyme ubiquitin specific peptidase 15 (USP15) is regarded as a regulator of TGFβ signaling pathway. This process depends on Smad7, the inhibitory factor of the TGFβ signal, and type I TGFβ receptor (TβR-I), one of the receptors of TGFβ. The expression level of USP15 seems to play vital roles in the pathogenesis of many neoplasms, but so far there has been no report about USP15 in psoriasis. In this study, immunohistochemical staining of USP15, TβR-I and Smad7 was performed in 30 paraffin-embedded psoriasis specimens and 10 normal specimens to investigate the expression of USP15, TβR-I and Smad7 in psoriasis and to explore the relevance among them. And USP15 small interfering RNA (USP15 siRNA) was used to transfect Hacat cells to detect the mRNA expression of TβR-I and Smad7. Of 30 cases of psoriasis in active stage, 28, 24 and 26 cases were positive for USP15, TβR-I and Smad7 staining, respectively. The positive rates of USP15 and Smad7 were significantly higher in psoriasis specimens than in normal skin specimens (44.1%±26.0% vs. 6.1%±6.6%, 47.2%±27.1% vs. 6.6%±7.1%), and positive rate of TβR-I (20.3%±22.2%) in psoriasis was lower than that in normal skin specimens (46.7%±18.2%). There was a significant positive correlation between USP15 and Smad7 expression, and significant negative correlations between USP15 and TβR-expression, an I d between TβR- and Smad7 expression I in psoriasis. After transfection of USP15 siRNA in Hacat cells, the expression of TβR-mRNA was up I -regulated and that of Smad7 was down-regulated. It is concluded that USP15 may play a role in the pathogenesis of psoriasis through regulating the TβR-I/Smad7 pathway and there may be other cell signaling pathways interacting with USP15 to take part in the development of psoriasis.

Abstract: Schistosomiasis is a serious major parasitic disease that threatens human life and health. A better understanding of the mechanism of host-schistosome interactions is the key to designing new prevention and control strategies. MicroRNAs (miRNAs) are endogenous small non-coding RNA molecules, which lead to the degradation of the target messenger RNA (mRNA) or inhibition of its translation in a sequence-specific manner. Both schistosome and its host produce miRNAs, which can be secreted by extracellular vesicles (EVs). There is accumulating evidence that miRNAs from schistosome can be taken up by host cells, and finely manipulate the phenotype of host cells for their survival or pathogenesis in a cross-species manner, even inhibiting the growth and metastases of hepatoma cells. It is still unknown whether host free miRNAs can be taken up by schistosome, but this phenomenon is highly probable. miRNA-mediated cross-species regulation has emerged as a novel mechanism for host-schistosome interactions, and this review summarizes the advances in this regard.
