AIM: To analyze the reasons of low vision and blindness in elderly patients and the application of optical aids in rehabilitation.METHODS: Totally 87 elderly patients which had 74 cases of low vision,13 cases of blind,including 53 males and 34 females.Routine internal and external eye examinations should be performed,and special removal examinations should be performed if necessary.Both refractive correction,and try with far and near optical aids,check after wearing a typoscope distant and near vision,distant vision ≥0.05 out the blindness,distant vision ≥0.3 out the disability.Near vision ≥ 0.5 was valid,<0.5 was invalid.RESULTS: Among 87 elderly patients with low vision,high myopia was the leading cause of blindness,followed by macular degeneration,cataracts,glaucoma and diabetic retinopathy.The visual acuity after refractive correction increased ≥ 2 lines in 62 cases (71%),visual acuity was not correct or corrected for ≤ 1 of 25 cases (29%).With aids,far visual was ≥0.3 of the 70 cases (80%),≥0.05 in 10 cases (11%),<0.05 in 7 cases (8%),residue removal rate of 92%.With reading glasses near and near visual acuity was >0.5 effective in 60 cases (69%),<0.5 ineffective in 27 cases (31%).Typoscope was often used in 58 cases,not often used 18 cases,11 cases rarely used or give up.CONCLUSION: High myopia is the leading cause of low vision and blindness in the elderly,followed by macular degeneration.The application of visual aids is still reliable and economical and effective treatment method,patients should be encouraged to use visual aids to improve the utilization rate of aids,so as to improve the quality of life of patients.

Objective To introduce the methods and cosmetic effect of reduction mammaplasty in patients with benign diseases of breast. Methods From December 1990 to November 2001, reduction mammaplasty was performed in 15 patients with breast hypertrophy, ptosis and benign diseases, including hamartoma (1 case), adenofibroma (1 case), lobular hyperplasia with adenofibroma (2 cases), mild papillomatosis (2 cases), ductal ectasia with secretion depot (2 cases), and lobular and ductal epithelial hyperplasia (7 cases). Nine patients received reduction mammaplasty using an inferior pyramidal pedicle technique, and six patients received Mckissock vertical bipedicle technique. Results The successful rate was high (89.6 %), except that three mammary glands developed necrosis of whole areola in Mckissock procedure group. Complications caused by breast hypertrophy and benign diseases were improved apparently. Conclusion Reduction mammaplasty is the best option for the treatment of breast hypertrophy and ptosis with benign diseases.

Objective To investigate the clinical significance of pulse high-volume hemofiltration (PHVHF) on expressions of Toll-like receptor (TLR) 2 and TLR4 mRNA in peripheral blood mononuclear cells (PBMCs) in patients with severe sepsis.Methods Forty patients with severe sepsis were divided into conventional treatment group (n =20) and PHVHF group (n =20) according to random number table.Another fifteen healthy volunteers served as controls.TLR2 and TLR4 mRNA expressions in PBMCs were detected using RT-PCR and plasma concentrations of TNF-α and IL-6 were measured using ELISA method before therapy and at 24 h,48 h and 72 h after therapy.Vital signs,BIL,Cr,BUN,Lac,PaO2/FiO2,acute physiology,chronic health evaluation Ⅱ (APPACHE Ⅱ),sequential organ failure assessment (SOFA) and prognosis were compared among the groups.Besides,complications associated with PHVHF therapy were monitored.Results Expressions of TLR2 and TLR4 mRNA in PBMCs and concentrations of TNF-α and IL-6 were significantly higher in patients with severe sepsis than in the controls (P < 0.01).At 72 hours after therapy,PHVHF group showed significantly lower concentrations of TNF-α and IL-6 than those before therapy (P < 0.01) as well as significantly lower expressions of TLR2 and TLR4 mRNA in PBMCs than those in conventional treatment group (P < 0.O1).However,no significant decline in the levels of TNF-α and IL-6 and the expressions of TLR2 and TLR4 mRNA in PBMCs were shown in conventional treatment group after therapy.At 72 hours after therapy,PHVHF group showed significant increases of MAP and PaO2/FiO2 and significant decreases of Cr,BUN,Lac,APACHE Ⅱ and SOFA as compared to those before therapy (P < 0.05).Moreover,the differences of MAP,PaO2/FiO2,Cr,BUN,Lac,APACHE Ⅱ and SOFA were statistically significant between and conventional treatment group at 72 hours after therapy (P < 0.05).Conclusion PHVHF achieves a reduced systemic inflammatory response,improved major organ functions,shortened length of stay in ICU and down-regulated TLR2 and TLR4 expressions in PBMCs that may be a novel mechanism of PHVHF in treatment of severe sepsis.

Objective To evaluate the value of neutrophil CD64 positive cells percentage(CD64%)detec-tion to stop using antibiotic in patients with severe pneumonia.Methods 60 accepted antibiotic therapy patients with severe pneumonia,in accordance with the random number table,were separated into observation group(n =30)and control group(n =30).Antibiotics were stopped according to CD64% in observation group,while it according to the clinical symptoms,the plasma level of white blood cell and C -reactive protein in control group.The main observation indexes included the days of antibiotics use,the length of Intensive Care Unit(ICU)stay,clinical efficacy and the case fatality rate.Results The days of antibiotics use in the observation group was (10.3 ±5.2)d,while it was (16.8 ± 5.8)d for patients in the control group,and it had significant difference(t =-4.570,P <0.01).The length of ICU stay in the observation group was shorter than that in the control group[(6.5 ±3.5)d vs (10.5 ±4.5)d],and it had significant difference(t =3.843,P <0.01).The clinical efficacy were 83.67% and 82.12%,and the case fatality rate were 9.68% and 10.24% in the observation group and control group,respectively,and both had no significant difference(P >0.05).Conclusion Stop using antibiotics according to the neutrophil CD64 % is safe,reliable,and can effectively reduce the excessive use of antibiotics and shorten the length of ICU stay in patients with severe pneumonia.

Objective To describe the anatomical variants of infants’internal cerebral veins and their tributaries with MR suscep-tibility weighted imaging,and to evaluate the capability in the visualization of cerebral deep veins.Methods 80 healthy infants were enrolled in this study.All the brain images were obtained by a 3D gradient-echo sequence (Enhanced T2 ? weighted angiography-ES-WAN)on a 3.0T MR,which were reconstructed with minimal intensity projection.The septal vein,thalamostriate vein,internal cerebral vein and anterior caudate nucleus veins were evaluated.4 types (ⅠA,ⅠB,ⅡA,ⅡB)were classified based on their rela-tionship with the septal vein-internal cerebral vein junction and interventricular foramen,and 3 types (Ⅰ,Ⅱ,Ⅲ)based on the drainage patterns of the anterior caudate nucleus veins.Results The septal vein,thalamostriate vein and internal cerebral vein could be clearly and continuously visualized in 100% infants,and the visualization rate of the anterior caudate nucleus veins was 88.1%. TypeⅠA and TypeⅠ were most common in the two classification patterns.Conclusion Infants’internal cerebral veins and their tributaries are able to be clearly shown with the minimal intensity projection in susceptibility weighted imaging,which is a good method to evaluate the cerebral deep veins in infants.
