RESUMEN
<p><b>OBJECTIVE</b>To report a newborn infant who died of alveolar capillary dysplasia (ACD). The literature on about 20 cases of ACD was reviewed.</p><p><b>METHODS</b>A retrospective review of records of infants from Medline with a diagnosis of ACD was carried out.</p><p><b>RESULTS</b>The case was a newborn female infant who developed respiratory distress 5 hours after an uncomplicated delivery. She died at the fourth day after birth despite full ventilatory support. The lung autopsy provided a diagnosis of ACD. In the 21 infants, 7 were male and 14 were female; 19 infants were born full-term and 2 were born pre-term. The birth weight of 19 infants and Apgar score of 15 infants were normal; 16 infants developed progressing tachypnea and cyanosis within 24 hours of age, 5 developed cyanosis at 1 day to 19 days. Echocardiography demonstrated a right to left shunt in the hearts of all the 21 infants, and pulmonary hypertension in 20 infants. Twenty infants were treated with conventional mechanical ventilation, 7 infants with high-frequency oscillatory ventilation and 12 infants with extracorporeal membrane oxygenation (ECMO). Fourteen infants were also treated with inhaled nitric oxide therapy and 4 with exogenous surfactant. Diagnostic open lung biopsy was performed in 6 infants. The chest radiography showed normal findings in 3 infants, pneumothoraces in 9 infants, reticular markings, granular, patchy or diffuse opacity in lungs of 7 infants, and decreased pulmonary vascular markings in two infants. All the 21 infants died; 8 of them died within 10 days of age, 7 within 30 days of age, and one died at the age of 4 months who was the longest survivor. Fourteen infants were associated with congenital malformations, such as cardiovascular, gastrointestinal, and genitourinary systems, including one infant associated with chromosomal abnormalities, two infants of familial genetic predisposition.</p><p><b>CONCLUSIONS</b>At present, ACD is still a disease with poor prognosis, significant medical expenses and no specific treatment. When respiratory failure or persistent pulmonary hypertension (PPHN) is persistent after routine treatment in an infant, ACD should be highly suspected and conventional open-lung biopsy should be preformed to confirm the diagnosis.</p>

Octenyl succinic anhydride (OSA) modified early Indica rice starch was prepared in aqueous slurry systems using response surface methodology. The paste properties of the OSA starch were also investigated. Results indicated that the suitable parameters for the preparation of OSA starch from early Indica rice starch were as follows: reaction period 4 h, reaction temperature 33.4 degrees C, pH of reaction system 8.4, concentration of starch slurry 36.8% (in proportion to water, w/w), amount of OSA 3% (in proportion to starch, w/w). The degree of substitution was 0.0188 and the reaction efficiency was 81.0%. The results of paste properties showed that with increased OSA modification, the starch derivatives had higher paste clarity, decreased retrogradation and better freeze-thaw stability.

Objective In order to improve the understanding of Kimura's disease,the clinical features and the pathological changes of 12 patients were analyzed.Methods Twelve cases with Kimura's disease ad- mitted to Qilu Hospital of Shandong University were retrospectively reviewed.Results All 12 patients were in relatively good condition and presented as subcutaneous nodules or swelling lymph nodes.Peripheral blood eosinophilia did not occur in 5 cases,4 out of 6 patients had high-level serum IgE.Biopsies were taken in all cases and the characteristic histological presentations were discovered.Only one patient developed pulmonary inflammation and acute myocardial infarction which were rare in Kimura's disease.Conclusions Definite di- agnosis of Kimura's disease mainly relies on biopsy.A patient with Kimura's disease can suffer from severe pulmonary and cardiac diseases,but the relationship between them should be studied further.
RESUMEN
Objective To investigate BAALC(brain and acute leukemia cytoplasmic)gene expression in patients with de novo acute myeloid leukemia(AML)and its clinical significance. Methods BAALC expression was determined by real-time quantitative polymerase chain reaction(RQ-PCR) in 63 de novo AML patients.The association between BAALC expression and therapeutic effect was analyzed.Results The correlation coefficiencies were over 0.99 for standard curves of RQ-PCR method. BAALC expression was detected in 49(78%)AML patients.The peripheral WBC counts,hemoglobin, platelet counts and the bone mahow blast cell percentage at onset in 31 AML patients with high BAALC expression were(26.3?18.1)?10~9/L,(78.3?21.8)g/L,(76.9?64.5)?10~9/L and(61.2?22.3)% and those of 32 AML patients with low BAALC expression were(30.2?21.7)?10~9/L,(81.6?30.9)g/L, (73.9?57.2)?10~9/L,(54.3?16.3)%,respectively.No statistic differences were found between these two groups.The AML patients with normal chromosome karyotypes are more likely to have a high BAALC expression(68%)compared with those with abnormal chromosome karyotypes(23%,?~2=12.093,P= 0.001).AML patients with normal cytogenetics and high BAALC expression shows significant lower CR rate (65%)compared with those with low BAALC expression(84%,?~2=6.573,P=0.013). Conclusion High BAALC expression may define an important risk factor in AML with normal cytogenetics and predicts an adverse prognosis.
