OBJECTIVETo investigate the main factors that influence measles morbidity and the genotype of measles virus, so as to provide evidence for scientific decision making to further control the prevalence of measles.

METHODA retrospective analysis included 182 children in Children's Hospital of Fudan University, diagnosed with measles from January 1, 2012 to December 31. The clinical and epidemiological characteristics, including the gender, age, the incidence of seasonal trends, measles vaccine vaccination history, contact history and other clinical manifestations, laboratory test results, and so on were analyzed. And the reverse transcription PCR (RT-PCR) was adopted to detect sputum specimens from suspected patients with measles,who were selected randomly,the sequence of the part of the PCR products was analyzed.

RESULT(1) Clinical and epidemiological data: Totally were 182 children with measles (125 males, 57 females) were enrolled into this study. The age of the patients ranged from 3 months to 89 months, 127 cases were younger than 9 months (69. 8%). The prevalence season was from April to August, while the peak month was April and May (22. 5%, 23. 1%). Among 182 hospitalized children, only 11 cases underwent measles vaccination (6. 0%), and among them 5 cases were within 2 weeks before disease onset. A total of 167 cases (91. 8%) had not been vaccinated, most of whom were immigrants, and the measles vaccination history of the remaining 4 cases were unknown. There was a positive correlation between the measles vaccination ratio in children of the floating population (8. 45%, 6/71) and the settled children (29.4%, 5/17, χ =8. 11 P =0. 004). In total, 24 cases (13. 2%) had definite measles exposure history, with 153 cases (84. 1%) of unknown origin,5 cases (2.7%) without any history of contact. (2) Clinical manifestations: All the 182 patients had fever (100%) and obvious rashes (100%), among them 145 cases had body temperature higher than 39 °C (79. 7%). The fever period ranged from 2 to 38 days. Among 182 hospitalized children,165 cases (90. 7%) had typical measles,17 cases had atypical measles. Among the 17 cases, two had severe measles, one had heterotypic measles. (3) The common complica tions: 96 cases had pneumonia (52. 8%), 80 had laryngitis (44. 0%), 38 had bronchitis (20. 9%),15 had hepatic dysfunction (8. 2%), 11 had myocardial damage (6. 0%), 3 had febrile seizures (1. 6%), and no patient had encephalitis. Of the 96 cases with pneumonia, 92 received sputum test; 38 were sputum culture positive (41%). The dominant pathogens were Streptococcus pneumoniae(11/38,29%), Haemophilus influenzae (6/ 38,16%), Moraxella catarrhalis (4/38, 11%), Escherichia coli (4/38, 11%), Candida albicans (4/38, 11%), Mycoplasma pneumoniae (4/38, 11%) and Staphylococcus aureus (3/38, 8%). (4) The H1a genotype was the only one genotype in the detected sequence of 54 measles virus strains.

CONCLUSIONMeasles was more often seen in the children under the age of 9 months from the floating population. The morbidity peak month was from April to May in Shanghai. The H1a genotype was the only one genotype. We should try to improve vaccination coverage rate in the children who are at the age for vaccination, so as to prevent measles outbreak.

Objective To investigate the effects of oxidative stress on homocysteine and related amino acids metabolism in methionine-loading BRL rat hepatocytes.Methods Cultured BRL rat hepatocytes were divided into control and oxidatively stressed group(100 μmol/L H2O2 was added in culture medium for 2 hours),methionine group(50 mmol/L methionine was added in culture medium for 1 hour),and oxidatively stressed + methionine group(100 μmol/L H2O2 was added in culture medium for 2 hours + 50 mmol/L methionine was added in culture medium for 1 hour).At the end of the experiment,culture fluid was collected.Homocysteine,cysteine,and glutathione were measured by high-performance liquid chromatography,and amino acids were assayed by amino acids analyzer.Results Compared with the control group,the contents of homocysteine[(3.76 ± 0.22)vs.(1.54±0.05)μmol/L,P=0.000]and cysteine[(199.80 ±8.75)vs.(99.11 ±2.47)μmol/L,P=0.000]significantly increased in methionine group,and the contents of homocysteine[(3.84 ± 0.34)vs.(1.54 ±0.05)μmol/L,P=0.000]and cysteine[(200.66±8.60)vs.(99.11 ±2.47)μ mol/L,P=0.000]also increased in oxidatively stressed + methionine group.Compared with oxidatively stressed group,the concentrations of homocysteine[(3.76 ± 0.22)vs.(1.67 ± 0.13)μmol/L,P =0.000],cysteine[(199.80 ± 8.75)vs.(82.64±15.88)μmol/L,P=0.000],and glutathione[(1.50 ±0.14)vs.(1.00 ±0.11)μ mol/L,P=0.011)]significantly increased in methionine group,and the concentrations of homocysteine[(3.84 ± 0.34)vs.(1.67±0.13)μmol/L,P=0.000],cysteine[(200.66±8.60)vs.(82.64±15.88)μmol/L,P=0.000]and glutathione[(1.40 ± 0.30)vs.(1.00 ± 0.11)μmol/L,P =0.028]significantly increased in oxidatively stressed + methionine groups.Compared with the control group,the contents of serine[(12.41 ± 1.51)vs.(24.00 ±2.54)mg/L,P =0.000],glutamate[(33.31 ±0.17)vs.(43.10 ±0.52)mg/L,P =0.000]and glycine[(6.23 ± 0.18)vs.(24.66 ± 10.87)mg/L,P =0.000]significantly decreased,while taurine [(7.99 ±0.16)vs.(6.17 ±0.15)mg/L,P =0.000]increased significantly in oxidatively stressed group.Compared with the oxidatively stressed group,the concentrations of serine[(16.98 ± 0.39)vs.(12.41 ± 1.51)mg/L,P=0.006)]and glutamate[(35.44 ±0.82)vs.(33.31 ±0.17)mg/L,P =0.002]in methionine group significantly increased,while taurine[(3.77 ±0.16)vs.(7.99 ±0.16)mg/L,P =0.000]significantly decreased in methionine group.Compared with the methionine group,the contents of serine[(12.59 ± 0.66)vs.(16.98±0.39)mg/L,P=0.008],glutamate[(30.87±0.60)vs.(35.44±0.82)mg/L,P=0.000]significantly decreased while taurine[(4.37 ± 0.12)vs.(3.77 ± 0.16)mg/L,P =0.001]in oxidatively stressed + methionine group significantly increased.Conclusion Oxidative stress can somehow promote homocysteine production in methionine loading BRL rat hepatocytes,but it is not the main effects.

Objective To establish the genetic test technique of trisomy 21 concurrently conducts with prenatal diagnosis for hereditary hearing loss. Methods Fifty-four pregnant women who underwent prenatal diagnosis for hearing loss of their fetuses in Chinese People's Liberation Army General Hospital from March 2009 to May 2010 were enrolled in this study. All probands from the deaf families have confirmed the causative mutation for hearing loss in Genetic Testing Center in Chinese People's Liberation Army General Hospital. The mean age of 54 pregnant women is 31 years at pregnancy of 18 - 26 weeks, 5 cases ＞ pregnancy of 23 weeks, 9 cases ≥ 35 years. All subjects did not conduct the serologic tests for trisomy 21before. Fifteen to twenty ml amniotic fluid was drawn from 49 cases at pregnancy of 18 - 23 weeks and 5 cases ＞ pregnancy of 23 weeks. One to two ml umbilical blood was drawn from 5 cases ＞ pregnancy of 23 weeks. For 9 cases ≥ 35 years, amniotic fluid cell culture and karyotyping analysis were conducted concurrently. A multiple quantitative fluorescent ( QF) PCR and six microsatellite markers were applied to as trisomy 21. Results (1) Fifty-four fetuses were successfully conducted prenatal genetic diagnosis for hearing loss (included GJB2 and SLC26A4). Ten fetuses copied the exactly same genotypes as the probands. The other 44 cases fetuses did not copy the same genotypes as the probands and won't develop hearing loss. The hearing test showed normal hearing for the neonates. (2) All the 54 fetuses were excluded of trisomy 21 by QF-PCR and were verified after birth. Five fetuses with advanced maternal age were performed karyotyping analysis and showed normal. The diagnostic results of QF-PCR can be obtained in 1 - 3 days without misdiagnosed. Conclusions QF-PCR is an efficient, rapid and accurate technique for detection of trisomy 21 without increasing sample amount. It can be used for fetuses who were undertaken hearing loss gene test or other prenatal gene test.

Objective To evaluate the optimum ratio of medicine dosage for dexmedetomidine mixed with sufentanil used for patient?controlled intravenous analgesia ( PCIA) after Nuss procedure in pedi?atric patients with pectus excavatum. Methods Sixty pediatric patients diagnosed with pectus excavatum, aged 5-12 yr, weighing 18-50 kg, of ASA physical statusⅠorⅡ, scheduled for elective Nuss procedure under general anesthesia, were randomly divided into 3 equal groups using a random number table:different ratios of medicine dosage while dexmedetomidine was added to sufentanil groups ( SD1-3 groups) . Postopera?tive analgesia was as follows: group SD1 received sufentanil 1 μg∕kg + dexmedetomidine 2 μg∕kg; group SD2 received sufentanil 1 μg∕kg + dexmedetomidine 3 μg∕kg; group SD3 received sufentanil 1 μg∕kg +dexmedetomidine 4 μg∕kg. A mixture of tropisetron 0?1 mg∕kg and dexamethasone 0?1 mg∕kg ( in 100 ml of normal saline) was added in each group. The PCA pump was programmed to deliver 0?5 ml with a lockout interval of 15 min and background infusion at 2 ml∕h. The PCA pump was connected immediately after the end of operation, and sufentanil with a dosage of 0?1μg∕kg was used as a rescue analgesic within 48 h post?operatively. The VAS score was maintained below 4. The requirement for rescue analgesics was recorded. The Ramsay sedation scores was recorded at 4, 8, 12, 24 and 48 h postoperatively, and the occurrence of adverse reactions such as nausea and vomiting, bradycardia, over?sedation, respiratory depression, agitation and shivering was recorded within 48 h after surgery. Results No pediatric patients developed nausea and vomiting, respiratory depression, bradycardia, over?sedation, and shivering. No pediatric patients required rescue analgesics in SD2 and SD3 groups. Compared with group SD1 , the requirement for rescue analgesics and incidence of agitation were significantly decreased, and Ramsay sedation scores were increased at 4 and 8 h after operation in SD2 and SD3 groups. Ramsay sedation scores were significantly higher at 4 h after oper?ation in SD3 group than in SD2 group. Conclusion Dexmedetomidine 3 μg∕kg mixed with sufentanil 1μg∕kg is the optimum ratio of medicine dosage when used for PCIA after Nuss procedure in pediatric patients with pectus excavatum.

Objective To assess the utility of single source-dual energy CT for distinguishing bladder cancer from hematoma. Methods We retrospectively identified 14 patients with postoperative or follow-up bladder hematoma who had undergone dual energy protocol (40-140 keV)scanning by single source-dual energy CT.The subjective scoring of tumor detection and image quality,the optimal monochrome images and iodine-water images were evaluated by two radiologists who didn’t know the results.The consistency of two observers was analyzed by Kappa test.Mann-Whitney U test was used to compare the difference between the two kinds of diseases and ROC curve was used to analyze the diagnostic efficiency.The statistical differences of image quality scoring among different images were obtained by using Mann-Whitney U test.Results The consistency of the two observers about scoring of lesion detection was good for all groups.There were statistical differences between two groups in non-enhanced phase and arterial phase of mixed-energy images,non-enhanced phase,arterial phase and delayed phase of optimal monochromatic images,and all phase of iodine-water images. The AUC of iodine-water images in the four phases (0.985,1.000,0.955,0.924,respectively)were all higher than that of polychrome unenhanced and arterial phase images (0.909,0.909).The diagnostic efficiency of arterial phase on iodine-water images was the highest.Sensitivity and specificity were both 100% when score was greater than 2.5.There was no statistical difference between two kinds of diseases on non-enhanced phase,delayed phases of mixed-energy or monochromatic images(P >0.05).There were no statistical differences in image quality scoring among the three groups with the same phases (P>0.05).Conclusion Optimal monochromatic images and iodine-water images of single source-dual energy CT are more effective than conventional CT in distinguishing bladder cancer from hematoma.
