Objective To explore the clinical characteristics and the remedial measurement of measles complicated with severe pneumonia and the acute respiratory distress syndrome(ARDS) in children.Methods From Jan 2004 to Jul 2007,clinical data of 32 cases with measles complicated with severe pneumonia and ARDS in PICU of Chongqing Children's Hospital were retrospective analyzed.In addition,the ratio of partial pressure of oxygen in arterial blood fractional concentration of oxygen in inspired gas[pa(O2)/FiO2] between the death group and survival group,the mortality rates between the hormone therapy group and control group were performed.Results Sixteen cases were cured and 16 cases were died,with the mortality rate 50%.The ratio of pa(O2) /FiO2 before mechanical ventilation in death group was lower than that in the survival group [(11.93?1.67) kPa,(21.77?1.16) kPa,respectively,P0.05).Conclusions ARDS is a severe complication in children with measles pneumonia and associated with a high mortality,which requires early diagnosis and intervention to improve survival rate and prognosis.The ratio of pa(O2)/FiO2 may provide reference to evaluation for severity and prognosis of ARDS.

Hyponatremia is relatively common in patients with neurologic disorders, while its diagnosis and treatment remain controversial. Osmotic demyelination syndrome (ODS) has shown to be closely associated with hyponatremia. ODS patients often present as central pontine myelinolysis, extrapontine myelinolysis, or both. This article reviews the clinical manifestations, pathogenesis, and risk factors of ODS in patients with hyponatremia caused by neurologic disorders.

AIM: To discuss the clinical efficacy of fresh amniotic membrane ( AM ) during the microscopic adjustable suture surgery in children's intercommunity strabismus, in order to guide clinical treatment.
METHODS: With the clinical randomized control study (RCT), 60 (112 eyes) cases of patients in childhood who received microscopic strabismus surgery in our hospital were divided them into two different groups from Jan. 2010 to Oct. 2015. According to the application of AM on the basis of ophthalmology outpatient number, 30 cases (58 eyes) in group A were treated with rectus muscle recession surgery combined adjustable suture combined with AM. The other 30 cases (54 eyes) in group B were treated with rectus muscle recession surgery combined adjustable suture only. All patients in two groups were followed-up over 6mo after the strabismus surgery.
RESULTS:Twenty-seven cases ( 48 eyes ) of all the strabismus patients must be adjusted after strabismus surgery, and the eye position adjustment rate was 42.9%. At 1mo after surgery, eye position of 18 cases (29 eyes) can be adjusted in all patients, and 44. 8% (16 cases, 26 eyes ) in group A with the average of adjustment lengths was 2. 56±0. 64mm, and 5. 6% ( 2 cases, 3 eyes ) in group B, with the average of adjustment lengths was 0. 52±0. 28mm, the differences of the adjustment rate and the average of adjustment amount were both high statistically significant (χ2 =22.477, P<0. 01; t=16. 502, P<0. 01 ) between the two groups. Except of 3 cases who couldn't cooperate with eye position adjustment, they all received eye position adjustment in different degrees in one month after strabismus surgery,and after eye position adjustment, 27 cases (53 eyes) in group A got normal eye position, and the correction rate of eye position was 91. 4%, and 16 cases (28 eyes) in group B got normal eye position after eye position adjustment, the correction rate was 51. 9%, the differences of the correction rate were statistically significant (χ2=21. 827, P<0. 01) between the two groups.
CONCLUSION: The application of fresh AM in the microscopic adjustable suture strabismus surgery is exactly effective in treatment of children's intercommunity strabismus. It can significantly extend the adjustment time and increase the adjustment amount, and it also can statistically improve the controllability and achievement ratio for children's strabismus surgery.

Objective To study the effect of cleaning intestinal tract on treatment jaundice in premature infants.Methods We randomly assigned 48 premature infants from January to December in 2004.In the treatment group the intestinal tract was cleaned with 30～40 mL NS once daily and 3～4 days.The through cutis bilirubin(TCB),the times of blue light,me conium exhustion and feeding toleration were recorded.Results 1.The TCB was obviously descented about 34.2 ?mol/L and the time of blue light was shortened by 20 h in treated group(P

Objective To study the anatomy basis and biomechanical stability of euthyphoria reduction and percutaneous cannulated screw fixation for sacroiliac dislocation,and to evaluate the primary clinical efficacy of this method.Methods The distances from the anterior branches of the nerve roots at L4,and L5 and obturator nerve on the superior border of sacral ala to the sacroiliac joint were measured on 12 adult cadavers (24 sides) fixed and preserved by formalin.Models of sacroiliac dislocation were made on six pelvic specimens of fresh cadavers.A comparison of stability was made on the six models between the fixation studied here and the traditional fixations by posterior percutaneous sacroiliac screws and by anterior sacroiliac joint plates.At the same time,17 patients with type C Tile fracture were treated with our method.The clinical efficacy was analyzed for the 17 patients.Results The distances from the anterior branches of the nerve roots at L4,and L5 and obturator nerve on the superior border of sacral ala to the sacroiliac joint were 20.24?1.20mm,23.80?1.43mm,and 16.26?2.07 mm respectively. There was no statistically significant difference in stability between our method and the traditional fixation by posterior percutaneous sacroiliac screws,though ours seemed better.Follow-ups for the 17 cases averaged 2.2 years,re- vealing fine functional recovery in all according to Matta scoring.Conclusions Euthyphoria reduction and per- cutaneous cannulated screw fixation can lead to sufficient biomechanical stability for the sacroiliac joint and effec- tively avoid nervous injuries.In addition,our method is simple and clinically effective,It is recommendable for small and middle-sized hospitals.

OBJECTIVE To investigate the HIV infections states in tumor patients for clinical diagnosis,treatment and to prevent HIV infection in the tumor hospital.METHODS The result of HIV detection in tumor patients from Dec 2000 to Aug 2006 was analyzed by the review statistics analysis.RESULTS Totally 48 101 tumor paients were detected,and the number of tumor patients with positive HIV antibody result was 51(0.106%).Among the positive patients there were 21 cases with blood transfusion history,14 cases with blood donating experience,2 cases with both these two kinds of experiences and 14 cases without the two kinds of experiences.Their rate was separately 41.0%,27.5%,4.0% and 27.5%.Most of the HIV positive patients had no clinical synptoms.CONCLUSIONS The HIV positive rate of patients with blood transfusion or blood donating is significantly higher than the patients without these experiences.The routine detection for the HIV before the operation,blood transfusion or other traumatic detection is very necessary.

Objective To explore the clinical efficacy and safety of transcatheter absolute ethanol injection treatment on varicose veins of lower extremity.Methods twenty-there patients with 25 varicose veins of lower extremity were treated by puncture of great saphenous vein above 1—2 cm of complicated inner ankle,perforating catheter to the point below the 3—4 cm of the conjunction of great saphenous vein and Femoral vein and pressing the conjunction of these two veins.Under the monitor of DSA,inject the absolute ethenal slowly while retrieve the catheter little by little(one limb with varicose veins injected total volume 15—20 ml),in the mean time,using contrast agent to monitor the level of embolism until the formation of total embolism in the all great saphenous veins.Results All the cases were retrospectively followed up with CDFI examination after 3—12 months of the surgery,No blood flow were seen in the 25 embolismic great saphenous vein.Clinical symptom were alleviated obviously after 2—3 weeks of treatment;varicose veins were collapse after 3 to 7 days.Two eases of leg ulceration were healed after 4 to 6 weeks of operation.20 limbs were found mild swelling in the 2 day after the surgery.However,all the cases were disappeared after 1 to 2 weeks;4 treated limbs developed delayed paresthesia in the 3 day after the surgery,and recovered totally in the 2 weeks.No complications of deep vein thrombosis,lung thrombosis etc al,were found after operation.Conclusions Using transcatheter injection of absolute ethanol to treat varicose veins of lower extremity has the advantage of less invasion,more safety and low appearance of complications.The short term efficacy is solid while the long term effect needs further evaluation.
