ABSTRACT
Objective To detect serum IgG4 and IgE levels in children with allergic asthma and rhinallergosis to provide an im-portant laboratory evidence for its diagnosis ,treatment and prevention.Methods The serum IgG4 and IgE levels were detected in 118 children patients with allergic asthma ,167 children patients with rhinallergosis and 150 healthy children(control group) under-going physical examination in the same period.Results The levels of serum IgG4 and IgE in the allergic asthma group and rhinal-lergosis group were significantly higher than those in the control group ,the difference was statistically significant (P0.05).Conclusion Serum IgG4 and IgE have a certain clinical significance in the occurrence ,treatment and surveillance of allergic asthma and rhinallergosis in children.
ABSTRACT
ObjectiveTo explore the clinical feature of severe hand, foot and mouth disease (HFMD) in pediatric patients, and to observe the hemodynamic changes in those with acute pulmonary edema.Methods A prospective observation study was conducted. Thirty-five severe HFMD pediatric patients with acute pulmonary edema admitted to the intensive care unit (ICU) and Department of Pediatric of First People's Hospital of Foshan from May 2008 to September 2014 were enrolled. The clinical features were thoroughly investigated. Hemodynamic data were monitored by pulse-indicated continuous cardiac output (PiCCO) in 5 cases, and the changes in PiCCO parameters were observed at ICU admission (0 hour), and 24, 48, 96 hours after treatment.Results Thirty-five patients who met the diagnostic standard of severe HFMD were enrolled, including 22 male and 13 female, aged from 7 months to 4 years. Six patients were younger than 1 year, 13 1-2 years, 12 2-3 years, and 4 patients 3-4 years old. The most common time of occurrence of pulmonary edema was 3-4 days after the onset of the disease. Fever and central nervous system symptoms were found in all the patients, and examination of the cerebral spinal fluid (CSF) revealed non-bacterial inflammatory changes. PiCCO results showed a tendency of lowering of heart rate (HR), systemic vascular resistance index (SVRI), and extravascular lung water index (EVLWI) after the treatment, and the values obtained at 96 hours were significantly lower than those at 0 hour [HR (bpm): 119.0±14.7 vs. 200.8±19.7, SVRI (kPa·s·L-1·m-2):148.9±14.6 vs. 209.6±58.7, EVLWI (mL/kg): 10.5±1.9 vs. 34.8±10.8,P< 0.05 orP< 0.01], global end-diastolic volume index (GEDVI) was also gradually decreased without significant differences among all the time points, together with a tendency of increase in stroke volume index (SI) and cardiac index (CI). The values of the parameters at 96 hours were significantly higher than those at 0 hour [SI (mL/m2): 38.5±6.5 vs. 17.4±2.8, CI (mL·s-1·m-2): 75.0±8.0 vs. 55.5±8.5, bothP< 0.01]. Left atrium was found to be enlarged, and left ventricular systolic function decreased in two patients by cardiac ultrasonic. Four out of 35 patients died, and functional disability of extremities was found in 1 patient. Other patients were cured and discharged without any sequelae.Conclusions Severe HFMD complicated by acute pulmonary edema is a perilous condition in children, accompanied commonly by pathologic changes in central nervous system and systolic dysfunction of left ventricle. According to the results with PiCCO monitoring, HFMD patients suffering from acute pulmonary edema may be of cardiac origin in addition to neurogenic origin.
ABSTRACT
To improve the teaching quality of neonatal diseases,we analyzed the diseases register of 760 neonates hospitalized in one year,two editions of textbook of pediatrics and the teaching outline,8 times of examination after the students had finished the exercitation.Accounted for 88.55%,673 cases of the neonates suffered from 15 diseases,which were included in the 17 diseases required by the teaching outline.Among the 669 cases of the neonates suffering from 10 common diseases,105 cases suffered from 5 diseases,which were not required by the teaching outline.As the second common disease,neonatal pneumonia was asked to be familiar with instead of mastering by the students.Accounted for 58.82%,10 diseases were required by the teaching outline without having them in the exams.Therefore it is important:1.to stand out the keystone on the clinic teaching of neonatal diseases such as neonatal jaundice,premature,and pneumonia which were required by the teaching outline as well as herpangina,vomit,humid lung-which were common diseases.2.to put neonatal vomit into the textbook and ask the students to master neonatal pneumonia.3.to perfect the setting of test paper:in the test paper neonatal diseases accounting for 20.00%,the diseases required by the teaching outline accounting for 85.00%.The proportion of important diseases to common diseases is 1.80∶1.
ABSTRACT
We analyszed 108 examination papers that were taken when the students of 8 groups had finished theexercitation. The attainment was 73.6?4.4 points. Among the 400 selective questions, the difficult questions whichwere concentrated only on a few diseases accounted for 35.3%. There was mush difference between the proportion of theselective questions and that of the demands of the teaching program in different system of diseases. There was few or noselective question in the important diseases of the teaching program. It is suggested that the proposition of difficultquestions must include the important diseases in the teaching program. The diseases that are not commonly encountereddiseases may be deleted from the teaching program, but the commonly encountered must be put in the teaching program.It is necessary to reinforce the ability of students to analyse and resolve problems[
ABSTRACT
Objective To investigate the relationship between newborn's feeding pattern and mother's knowledge-attitude-behavior in nutrition(K-A-B). Methods 246 pairs of mother and her newborn, 28?3 days old,were enrolled in the study,and questionnaire on the K-A-B was sent. Results The breaset-feeding rate of the newborn was 65.1%. 9.8% newborns were fed inappropriately. Only 65.5% mothers passed the examination of nutritional knowledge. However,88.5% mothers had positive attitude to receiving nutritional education. A lot of mothers have food preference. Nutritional lecture ,consultation in out patient department and by telephone were the nutritional education channels choiced by 78.5% mothers. Conclusion Breast-feeding rate of the newborns had been significantly reduced in comparison with that(85.1%) two years ago. Solid foods were given too early to the newborns. The major contributing factor is lack of knowledge in nutrition of mothers . Mothers should learn more about nutrition and improve their feeding skill through nutritional education.
ABSTRACT
Metronidazole derivative CMCa is a kind of radiosensitizers to tumor hypoxic cells. It can highly concentrated in cancer tissues. Acute toxicity assay revealed that ALD was 3.43 g/kg and MLD was 4.0g/kg. No significant changes in clinical symptoms, blood pictures and hepatorenal function were found at small dose (1g/kg), but at middle dose (2 g/kg) nausea and vomiting might occur but not significant in laboratory findings. However at larger dose (4.0 g/kg) the G-I and CNS symptoms were marked, and the cause of death was DIC. So, it can not be used in clinically at this dosage. Owing to the unstability of CMCa it should be prepared freshly before usage.
ABSTRACT
Lymphocyte chalone was partially purified by ultrafiltration and chromatography on Sephadex G75. Its inhibitory effect on proliferation of T, B lymphocyte was demonstrated by [3H]-TdR incorporation method. In mouse bone marrow transplantation model, the treatment with lymphocyte chalone in vivo and in vitro was found to significantly improve the 30 d survival rate and prolong mean survival time, suggesting that it has an inhibitory effect on acute GVHD and is beneficial to H-2 incompatible bone marrow transplantation in mice.
