ABSTRACT
Objective:To investigate the clinical characteristics and related risk factors of sarcopenia in elderly patients undergoing maintenance hemodialysis.Methods:This was a retrospectively study involving 135 elderly hemodialysis patients aged(70.6±7.7)years, with 46(34.1%)females and a mean hemodialysis duration of(3.2±2.9)years, at Shanghai Sixth People's Hospital.The incidence of sarcopenia in patients was examined by measuring handgrip strength, walking speed and muscle mass of the limbs using bioelectrical impedance analysis.Related risk factors were analyzed with univariate and multivariate logistic regression analysis.Results:Among 135 elderly hemodialysis patients, the incidence of sarcopenia was 62.9%(85 cases), and severe sarcopenia cases accounted for 44.4%(60 cases). Compared with the non-sarcopenia group, patients with sarcopenia were older, had lower body mass index(BMI)and handgrip strength, walked more slowly and had less muscle mass in their limbs.Advanced age, low BMI and long dialysis duration were correlated with the high incidence of sarcopenia in elderly dialysis patients.The odds ratio( OR)for sarcopenia increased by 12% per year, and the OR decreased by 32% with an increase of 1.0 kg/m 2 in BMI.Advanced age and lower BMI were also correlated with a high incidence of severe sarcopenia( OR=1.12, 95% CI: 1.05~1.18; OR=0.84, 95% CI: 0.74~0.95; all P<0.01). Conclusions:The incidence of sarcopenia is high in elderly hemodialysis patients and is closely related to advanced age and low body weight.Improving nutritional status and avoiding low body weight will help reduce the occurrence and development of sarcopenia in elderly hemodialysis patients.

ABSTRACT
Background Immediately ocular rinsing is a key step for the prevention of eye tissue damage after acute chemical bums.A good ophthalmic rinsing solution can neutralize chemical substance and improve the prognosis of patients.Objective This study attempted to evaluate the therapeutic effect of self-made citric aciddisodium hydrogen phosphate buffer and citric acid-disodium hydrogen phosphate-potassium chloride buffer on corneal chemical burns in mice.Methods Citric acid-disodium hydrogen phosphate buffer solution (solution 1) and citric acid-disodium hydrogen phosphate-potassium chloride buffer solution (solution2) with the pH 7.4 were prepared.One hundred and twenty clean male C57 mice aged 6-8 weeks were randomized to two groups,and filter papers containing 1 mol/L H2SO4 or 0.15 mol/L NaOH were attached to the central corneas of the right eyes to create the acid or alkali burning models.Then the eyes were immediately rinsed by 40 ml solution 1,tap water or solution 2 according to the grouping and the model eyes without rinsing served as the control group.The corneal opacity was examined by slit lamp microscope and scored in 3,7 and 14 days after modeling.The percentages of corneal fluorescein staining,corneal neovascularization and corneal ulcer were analyzed.The study protocol was approved by Experimental Animal Ethic Commission of Second Military Medical University.Results In the corneal acid burning models,the number of eye with corneal opacity scored 1 in the solution 1 group,tap water group and solution 2 group was significantly more than that in the non-rinsing group in 3,7 and 14 days after modeling (all at P＜0.01);In 3 days after modeling,the numbers of eye scored 1 were more in the solution 1 group than those in the tap water group and solution 2 group (x2 =11.000,P =0.001;x2 =4.000,P =0.046).There were no differences in the eye number of different corneal opacity scores in 14 days after acid burning (all at P＞0.05).In 3,7 and 14 days after corneal alkali burning,the number of eyes with corneal opacity scored 1-2 was significantly increased in the solution 1 group,tap water group and solution 2 group compared with non-rinsing group (all at P＜0.01).The percentage of corneal ulcer in the solution 1 group,tap water group and solution 2 group was 7％,27％ and 13％,respectively,which was significantly lower than 73％ in the non-rinsing group (P =0.000,0.027,0.003),and no significant differences were seen in various time points after corneal alkali burning (all at P＞O.05).Corneal neovascularization occurred in 50％ mice in non-rinsing group in 14 days after acid burning.However,no neovascularization was seen in the mice of the solution 1 group,tap water group and solution 2 group in both acid and alkali burning mice.Conclusions Citric aciddisodium hydrogen phosphate buffer (pH 7.4) appears to be an effective emergency rinsing solution for corneal chemical burns and the rinsing solution with or without potassium chloride is not obviously affected to the prognosis of corneal chemical burns in the mice.
ABSTRACT
Objective: To study the mRNA and protein expressions of ICAM 1 and CD44s in non small cell lung cancer as well as nearby normal lung tissue. Methods: RT PCR and SP immunohistochemistry were used to detect the mRNA and protein expressions of ICAM 1 and CD44s in 42 non small cell lung cancer and nearby normal lung tissue. Results: The expression level of ICAM 1 and CD44s increased in NSCLC tissue than in normal tissue. No correlations were noted in expression of ICAM 1 and CD44s and pathological type, histological differentiation and TNM stage. But there was significant correlation between abnormal expressions of ICAM 1 and CD44s and lymph node metastasis. Conclusion: These results suggest that the level of ICAM 1 and CD44s genes expression in lung cells increases as they progress from normal to the transformed stage, that indicate these two genes are involved in the process of lung cancer development.
