Objective To understand the arsenic level in drinking water and the current situation in prevention and control of endemic arsenic poisoning in Tuyouqi,Baotou of Inner Mongolia.Methods Through door-to-door survey,we selected patients with arsenic poisoning in order to monitor the arsenic poisoning condition of seven villages(Gangfangying,Laohuyao,Shilaozhang,Youfangying,Wanglaosi,Dajing and Xiaojing) in Tuyouqi,Baotou in 2010,and the disease was diagnosed based on Standard of Diagnosis for Endemic Arsenism(WS/T 211-2001).We also investigated the operation of Salaqi Water Company,Maodai Water Company and the Laohuyao water improvement project.We collected two samples per place in both low water period and high water period to measure water arsenic with silver diethyldithiocarbamate spectrophotometry(WS/T 28-1996).Results Three water improving projects were operating in normal conditions.Water arsenic in Salaqi Water Company and Maodai Water Company was level less than 0.01 mg/L,which met the National Safety Standards of drinking water with arsenic.Water arsenic in Laohuyao improvement project was 0.053 mg/L,which was higher than the drinking water safety standards.The seven villages in Tuyouqi had improved their water conditions.Among them,the arsenic level in Laohuyao was 0.052 mg/L,and the remaining six villages were < 0.05 mg/L.There were 6 suspected cases,14 mild cases,4 moderate cases and 10 severe cases of the 2095 people monitored and no new cases found.The age of patients with arsenic poisoning was in the range of 40 to 70.Conclusions The monitoring results show that drinking water arsenic level in some villages in Tuyouqi is still excessive,but no new arsenic poisoning patients in arsenic poisoning areas are found.

Background Econazole nitrate is not effective as an antifungal eyedrop because of its poor intraocular permeability,therefore changing the formulation of econazole nitrate to improve its intraocular permeability become a critical point in the treatment of intraocular fungal infection. Objective The present study was to observe the penetration of 0.5% econazole nitrate nanoparticles in the corneas and aqueous humors following its topicaladministration. Methods Econazole nitrate nanoparticles were prepared by quasi-emulsion solvent diffusion.Characteristics and size of nanoparticles were examined with transmission electron microscope and laser scatteringmethod,respectively.Econazole nitrate nanoparticles drops (0.5% )was topically administered in 27 New Zealandwhite rabbits bilaterally,and aqueous humor and corneas were obtained after the application of the eye drops for 5,15,30,45,60,90,120,180,240 minutes respectively to detect the concentration of econazole nitrate with highperformance liquid chromatography (HPLC). The pharmacokinetic parameters were calculated with 3 p97pharmacokinetic computer software.The use of the animals followed the Regulation for the Administration of AffairsConcerning Experimental Animals by State Science and Technology Commission. Results The diameter of thenanoparticles was 50 nm with the round shape and encapsulation efficiency was 96.0%.Econazole nitrate nanoparticlesat the concentration of 0.5% could be rapidly separated with other elements by HPLC with a lowest quantitativeconcentration of 0.1 mg/L.The mean recovery rates of econazole nitrate nanoparticles were 98.09% in cornea and 99.66% in aqueous humor,respectively after topical administration.The peak levels of econazole nitrate nanoparticles in cornea and aqueous humor were achieved at 5 minutes after application ( cornea:40.620 μg/g± 7.756 μg/g;aqueous humor:0.504 mg/L±0.153 mg/L),and its half-life( t1/2 )in cornea and aqueous humor was 23.5 minutes and 18.6 minutes,respectively. Conclusions Econazole nitrate nanoparticles at 0.5% concentration can remain a feasible bioavailability in ocular tissue and therapeutic level in cornea and aqueous humor.

BACKGROUND:Due to special physiological and anatomical location, stability of the spine is very complicated during thoracolumbar fractures. It is difficult to identify the stability of the spine. It should be based on their individual circumstances, to explore more effective internal fixation repair method.
OBJECTIVE:To explore the Cobb’s angle and vertebral height of patients with thoracolumbar fracture and spinal cord compression treated with posterior laminectomy and screw fixation, and compared with anterior laminectomy.
METHODS:One hundred patients with thoracolumbar fracture and spinal cord compression, who were treated in the Panyu District Central Hospital from January 2013 to November 2014, were enroled in this study. The patients were equaly and randomly divided into posterior laminectomy fixation group and anterior laminectomy fixation group. Tactile and sports of American Spinal Injury Association scores, Cobb’s angle and vertebral height were assessed before treatment and 1 month after treatment, and fixation effects were compared between the twogroups.
RESULTS AND CONCLUSION:(1) No significant difference in each index was detected between the two groups preoperatively (P> 0.05). (2) Tactile and sports of American Spinal Injury Association scores, Cobb’s angle and vertebral height were better in the posterior laminectomy fixation group than in the anterior laminectomy fixation group at 1 month postoperatively (P< 0.05). (3) These findings indicated that compared with the anterior laminectomy fixation, posterior laminectomy fixation for thoracolumbar fracture combined with spinal cord compression obtained better outcomes, and could obviously relieve spinal cord compression. Posterior laminectomy fixation isasafe and effective treatment method for thoracolumbar fracture and spinal cord compression.

Objective To evaluate the efficacy and safety of the bundles of treatment protocol for patients with acute brain injury (ABI) complicated by acute lung injury (ALl)/acute respiratory distress syndrome (ARDS).Methods A total of 83 patients with acute brain injury complicated by ALI/ARDS were randomly divided into experimental group (n =41) and control group (n =42).The control group was treated with the routine bundle protocol while the experimental group was treated with an intensive bundle protocolin addition to the routine bundle protocol.The data was collected,and the effectiveness and safety of the two bundles of treatment protocol were evaluated.Results The results of heart rate (HR),SpO2,and PO2/FiO2 in the two groups showed significant differences before and after treatment.The improvement of PO2/FiO2 in the experimental group occurred earlier and was more significant compared tothe control group,24 hours after treatment.The mechanical ventilation time,ICU stay time,and total hospitalization time for the experimental group were significantly different (P < 0.05) from the control group.The 28-day mortality and morbidity of ventilator-associated pneumonia showed no significant difference (P > 0.05) between the two groups.Conclusion The treatment of acute brain injury complicated by ALI/ARDS by the two bundles of treatment protocol is effective.Compared to the conventional treatment bundles,the intensive treatment bundles can significantly improve oxygenation,and shorten the mechanical ventilation time required,as well as ICU and total hospital stay.
