OBJECTIVE: To analyze the medical records of poisoned children to provide references for the forensic identification of melamine-tainted milk powder poisoning. METHODS: Medical records of six fatal cases of consuming some brand melamine-tainted milk powder were studied, specifically the poisoning symptoms, medical imaging, blood biochemical tests, treatment and prognosis. RESULTS: The major medical problems of these eight-month sick infants were urinary tract obstruction caused by urinary tract calculi. The poisoned infants developed oliguria, anuria and other symptoms, eventually, acute renal failure or other complications leaded to death. The serum BUN and Cr abnormally increased. CONCLUSION By considering the toxicological effects of melamine, it was concluded that the deaths of these sick infants were related to the melamine poisoning.

OBJECTIVETo understand the clinical features of gastrointestinal cow's milk allergy in children, and to assess the importance of cow's milk challenge.

METHODAn analysis was performed on the clinical manifestations and the challenge results of 50 children who received cow's milk challenges after admission to the department of gastroenterology, Children' s Hospital of Zhejiang University School of Medicine from January,2009 to December, 2012. The value of immunoglobulin E antibody was also analyzed among the 50 children, 25 cases were male and the other 25 were female. The youngest subject was 1. 6 months old, and the oldest was 20 months, most of the cases were younger than 6 months (36 cases).

RESULT(1) Diarrhea (27 cases, 54%) and hematochezia (25 cases, 50%) were the most common clinical features, vomiting, hematemesis and abdominal distention were rare. (2) Cow's milk challenges failed in 58% of the cases, 90% of whom showed delayed allergy. Diarrhea (19 cases, 73%) was the major later presentation, whereas the immediate hypersensitivity showed angio-edema, gastrointestinal symptom and rash. (3) The neutrophil count ((3.8 ± 2.8) x 10(9)/L vs. (2.5 ± 1.3) x 10(9)/L) was higher after challenge among children who failed the challenge. The change in the count of blood cell, neutrophil and platelet was studied, however, there were no statistical differences between the challenge-failed children and the passed ones. (4) Forty-seven cases had milk specific immunoglobulin E antibody test, and 5 showed positive results, 4 of whom were seen among the challenge-failed children.

CONCLUSIONDiarrhea and hematochezia was the most common clinical manifestation, and cow's milk protein induced proctocolitis was the most common disease in practice. It is important and necessary to perform cow's milk challenge.

Objective To investigate the difference and significance of the glucocorticoid receptors of the peripheral leukocytes in patients with acute spinal cord injury or with chronic spinal cord compression. Methods Glucocorticoid receptors binding sites on the peripheral leukocytes in 20 patients with acute spinal cord injury and 21 patients with chronic spinal cord compression were measured by the radioligand binding assay. Results Glucocorticoid receptors binding sites on peripheral leukocytes from the patients with acute spinal cord injury is 2 517?857.8 per cell, the patients with chronic spinal cord compression is 4 225?1 271 per cell and outcome is 2 279?921 per cell in the patients with complete paralysis, 2 806?718 per cell in the incomplete paralysis patients. T test was used to evaluate the final outcome. Conclusion Glucocorticoid receptors binding sites on the peripheral leukocytes consist of two kinds: the high affinity binding sites and the low affinity binding sites. The high affinity glucocorticoid receptors binding sites on peripheral leukocytes in patients with acute spinal cord injury decrease and low affinity binding sites remain unchanged. Large doses of glucocorticoid combine the low affinity binding sites on peripheral leukocytes which inhibits the tendency of movement of leukocytes to the injured spinal cord; so inflammatory reaction produced by acute injury can be alleviated and thus the spinal cord was protected. There is no curative effect by using large doses of glucocorticoid to treat patients with chronic spinal cord compression.

Objective To investigate correlation between serum C-reactive protein (CRP) level and severity of disease and outcome in cerebral infarction (CI).Methods Ninety patients with CI within onset of 2 weeks were evaluated by National Institutes of Health Stroke Scale (NIHSS) and Barthel index (BI) at admission and 3 months later. Serum CRP level were measured at admission. Correlation analysis was performed between serum CRP level and NIHSS, BI scores.Results The patients were divided into group A [( 1.23?0.32)mg/L], group B [( 5.04?1.93) mg/L]and group C [( 25.34?14.27)mg/L] according to different serum CRP level. Serum CRP level correlated significantly with severity and outcome at admission and 3 months later ( r=0.40, 0.42, -0.55,-0.44,respectively, all P

OBJECTIVE To discuss the mycology characteristic of two strains of Rhodotorula glutinis causing infection in ICU,and conduct molecular biological identification and antifungal agent sensitivity experiment.METHODS The methods used included conventional mycology identification and sequencing the ITS region of strains,and the in vitro antifungal agent sensitivity experiment were done by glutinis liquid-based dilution method(M27-A).RESULTS The two strains of R.glutinis were confirmed after mycology identification and sequenced the ITS region of strains.They were both sensitive to amphotericin B and 5-flucytosine,and insensitive to fluconazole,itraconazole and voriconazole.CONCLUSIONS The reasons causing Rh.glutinis infection include catheter related infections,(total parenteral nutrition TPN) and immunosuppressives.Using amphotericin B and removing intravenous catheter can be the first choices in the treatment of Rh.glutinis infection.Azole shows insensitive to Rh.glutinis in the in vitro antifungal agent sensitivity experiment,therefore it should be used very carefully.

Objective:This study investigated 376 adolescents' interpretations to peer rejection events. Methods:Measuring 376 adolescents' degrees of peer acceptance and their interpretations to peer rejection events by means of pen and paper questionnaires.Results:Peer-rejected adolescents presented a similar way of general interpretation to rejected events happened in other peers,however they interpret their own rejected events in a completely different way compared with popular adolescents:The main effects of peer acceptance types were significant on objective and subjective question scores(F(3,344)=3.212,P=0.023;F(3,344)=4.059,P=0.007, respectively);and there was a significant interaction effect of sex?age?peer acceptance types (F(9,344)=3.447, P

Objective To observe the expression of resistin mRNA and protein in adipose tissues of obese rats,and to explore the correlations between resistin and obesity,insulin resistance.Methods Thirty SD rats were divided into control group(n=15) and high-fat diet group(n=15).The rats in control group recieved common forage.The obese and insulin resistance models were induced with high-fat diet in SD rats.The plasma insulin level was determined by double antibody radioinimunity analysis,and automatic biochemistry analyzer in plement was used to detect the plasma free fatty acid.After 11 weeks,glucose tolerance test was carried out to determine blood glucose levels at intervals(0,30,60,90,120 min).Resistin mRNA from fat pads tissue was extracted by RT-PCR,and then its protein was detected by Western blot.The data were analyzed statistically by SPSS 11.5 software.Results After 11 weeks,the rats′ weight in high-fat diet group increased obviously than that of control group,as well as fasting blood glucose,free fat acid homeostasis model assessment of insulin resistance(HOMAIR) and the glucose tolerance in high-fat diet group reduced greatly.The resistin mRNA and protein in white adipose tissues were significantly higher in the obese mice than those of control group(Pa
