RESUMO
@#Objective To investigate visual impairment students' quality of life and its influencing factors in Braille learning class at Quanzhou Special School. Methods November, 2020, 52 students (aged seven to 26) with the best corrected distance visual acuity of the better eye above 0.02 were investigated with near visual acuity, contrast sensitivity and Chinese-version Low Vision Quality of Life Questionnaire (CLVQOL). The subjects were divided into second grade blindness group, first grade low vision group and second grade low vision group according to the best corrected distance visual acuity of the better eye. Results There were significant differences in distance visual acuity (Z = 45.671, P < 0.001), near visual acuity (Z = 24.972, P < 0.001), and contrast sensitivity (CS) ( Z = 13.285, P = 0.001) among three groups. There was a correlation between near visual acuity and distance visual acuity (r = 0.74, P < 0.001), CS to distance visual acuity (r = -0.58, P < 0.001) and near visual acuity (r = -0.57, P < 0.001), score of CLVQOL and CS (r = 0.44, P < 0.001). There were significant differences in the total score (Z = 10.145, P = 0.006), distance visual acuity subscale (Z = 13.586, P = 0.001), psychological adjustment subscale (Z = 7.824, P = 0.020), reading and fine work subscale (Z = 7.923, P = 0.019) of CLVQOL among the three groups. Conclusion Quality of life is different with the visual impairment for students in special school, especially the distance visual acuity, psychological adjustment and fine reading. CS correlates to the quality of life of visually impaired students, which needs to be a part of evaluation of visual function.
RESUMO
Objective To study the effect of transsphenoidal approach operation for pituitary adenoma.Methods Transoral and transsphenoidal approach operations were performed in 17 patients with pituitary adenoma,and transnosal and transsphenoidal approach operations were performed in 31 patients with pituitary adenoma,from January 2000 to December 2005.For transoral and transsphenoidal approach operations,the upper lip mucous membrane was opened to introduce into the nasal cavity.For transnosal and transsphenoidal approach operations,the instruments were inserted by way of the right nostril,and the nasal septum was opened.During both of the approaches,a tunnel was established between both sides of the nasal septum,through which the sphenoidal sinus was opened,for entering the sella through the bottom.Results Total resection was completed in 37 patients,subtotal resection was completed in 6,and partial resection,in 5.No surgical-related death occurred.Postoperatively,transient hyperuresis was found in 15 patients,and cerebrospinal fluid rhinorrhea was seen in 7 patients.Seventeen patients were followed for 3～24 months(mean,12 months).Recurrence was encountered in 4 patients at 6 months after operation.Four patients were pregnant and delivered of a child.Conclusions For pituitay adenoma not obviously extending to the parasellar,transsphenoidal approach is a safe and effective option.
RESUMO
Objective To establish a new method for determination of trace cadmium in river water. Methods Cadmium in river water was separated and enriched with sulfhydryl cotton, in the presence of 4?10~3 % emulsifier OP and H3PO4-NaH2PO4 water solution, Victoria Pure Blue BO reacted with [CdI4]2- forming an ionic-associated complex and the color of the solution changed from yellow to pure blue, and the content of trace cadmium in river water was determined by spectrophotometry. Results When cadmium was enriched fifty times, the apparent molar absorptivity of the associated complex was ?=2.79?10_5 L/(mol?cm). Beer's law was obeyed in the range 2-100 ?g/L. The recovery rate and RSD of the method was 96.2%-98.6% and 2.5% respectively. Conclusion The method was accurate and sensitive,and was suitable for determination of trace cadmium in river water.
RESUMO
OBJECTIVE:To assess the application value of large dose of naloxone hydrochloride in treating early stage craniocerebral trauma.METHODS:79craniocerebral trauma cases whose GCS scores were5to8scores were enrolled:38(control group)were randomly assigned to receive conventional therapy(dehydrating agent,glucocorticoid,antibacterials,nu?tritional brain cells,and so on),and41(naloxone group)to receive additional naloxone besides the conventional therapy as stated in the control group.Variations on GCS scores,serum?-endorphin(?-EP)level,indexes of respiration and circulation,and safe consciousness time of the2groups after treatment were observed.RESULTS:As compared with the control group,naloxone group had shorter safe consciousness time,lower incidences of respiration failure and circulatory failure,more and faster decrease of serum?-EP level(P
