Objective To assess the value of combined detection of enterovirus nucleic acid and antibody in early etiological diagnosis for hand-foot-and-mouth disease ( HFMD).Methods A case-control study was conducted.A total of 1 066 cases of children clinically diagnosed with HFMD from Hangzhou Children′s Hospital were involved into the research group from January to June 2014, consisting of 401 common cases and 665 severe cases; Throat swabs and serum samples from these children underwent combined detection for EV71/CA16/EV of enterovirus nucleic acid by fluorescence quantitative RT-PCR and for EV71/CA16-IgM by ELISA.All data were analyzed with SPSS 16.0.Results The total positive rate of enterovirus nucleic acid EV71/CA16/EV by fluorescence quantitative RT-PCR in the 1 066 cases of children clinically diagnosed with HFMD was 75.52%( 805/1 066 ) ( 95%CI: 72.80%-78.05%).But the total positive rate of combined detection was 91.46%( 975/1 066 ) ( 95%CI:89%.58-93.04%).The total positive rate of combined detection is higher than that of RT-PCR test(χ2 =98.338,P=0.000).The positive rate of EV71 type of combined detection was 64.63%(689/1 066)(95%CI:61.67%-67.49%),which is 15.38%higher than that of RT-PCR test 49.25%(525/1 066)(95%CI:46.21%-52.29%)(χ2 =51.453, P=0.000).In 665 severe cases of HFMD, the total positive rate of combined detection was 96.69%(643/665)(95%CI:94.95%-97.87%), which is higher than that of RT-PCR test 79.25%(527/665)(95%CI:75.92%-82.22%)(χ2 =95.607, P =0.000).In the severe cases, the positive rate of EV71 type of combined detection was 87.52%( 582/665 ) ( 95%CI:84.71%-89.89%) , which is 18.95% higher than that of RT-PCR test 68.57%(456/665) (95%CI:64.87%-72.06%) (χ2 =69.665, P=0.000).In the fatal cases, the positive rate of EV71 type of combined detection was 95.92%(94/98) (95%CI:89.28%-98.68%).Conclusions The combined detection of enterovirus nucleic acid and specific IgM antibody can significantly increase the positive rate of HFMD, especially for severe cases.The combine detection increases both the total positive rate and EV71 positive rate.Thus it has a high potential for becoming a new guidelines for laboratory diagnosis of HFMD.

Objective To explore the clinical application value of serum amyloid A (SAA),C-reactive protein (CRP) and SAA/CRP in early diagnosis of hand-foot-mouth disease (HFMD).Methods The serum levels of SAA and CRP were detected in 873 children with HFMD who were admitted in Hangzhou Children's Hospital from April to December in 2015.And 487 healthy children were enrolled as healthy control group.SAA was measured by nephelometry assay,and CRP was measured by immunoturbidimetry.Variables were compared using Mann-Whitney U test and diagnostic value was measured by using receiver operating characteristic (ROC) curve.Results The median levels of SAA in HFMD group and control group were 330.5 and 4.0 mg/L,respectively,which was statistically different (Z=-29.02,P＜0.01);the median levels of CRP were 10.0 and 1.0 mg/L,respectively,with statistical difference (Z =23.79,P＜ 0.01);and the median SAA/CRP were 23.06 and 2.40,respectively,with statistical difference (Z=-24.79,P＜0.01).In ROC curve comparison,the area under the curve of SAA (0.980) was higher than those of SAA/CRP ratio (0.911) and CRP (0.899) for diagnosing HFMD.When using 10.30 mg/L as the cut off value for SAA according to the ROC curve,the sensitivity was 91.6％ and the specificity was 96.6％.Conclusions Joint detection of SAA and CRP can improve the efficiency in the early diagnosis of HFMD.SAA can provide useful auxiliary information for the diagnosis of HFMD,which is worthy of extensive clinical application.

Objective:The poor prognosis of patients with malignant gliomas (MG) has led to the search for new therapeutic strat-egies. Recently, nimotuzumab has been studied as a new anti-EGFR-receptor humanized monoclonal antibody in patients with MG, who showed improvement of outcome and good tolerability. We conducted phase I of our study to determine the toxicity, tolerated dose, and clinical feasibility of nimotuzumab in combination with concurrent chemoradiotherapy for Chinese MG patients after surgical resection. Methods:Patients with pathologically proven grades 3 and 4 glioma were enrolled in the study. The protocol included infu-sions of nimotuzumab plus standard Stupp schedule (postoperative radiotherapy in a total dose of 60 Gy in combination with daily te-mozolomide). Patients received 6 weekly infusions of nimotuzumab at three levels (100, 200, and 400 mg/week). If none of the first three patients enrolled at a dose level experienced dose-limiting toxicity (DLT), the dose was increased, as appropriate. If DLT was ob-served, another three patients were added to the dose level. Results:Nine patients with MG were enrolled, including 7 with grade 3 MG and 2 with glioblastoma. The treatment was well tolerated, and no evidence of grade 3 or 4 adverse events was detected, even at the highest level (400 mg/week). Grade 1 or 2 myelosuppression was the most common toxicity. Three months after treatment, stable dis-ease occurred in 5 patients, whereas progression disease was observed in 4 patients. Conclusion:Nimotuzumab combined with concur-rent chemoradiotherapy was associated with mild toxicity in Chinese MG patients.

Objective To develop a method of simultaneous detection and Gram classification for pathogens causing sepsis with gram-specific probes based real-time PCR. Methods A pair of universal primers and a set of probes including Gram-positive probe and Gram-negative probe were designed based on the bacterial highly conserved region of 16SrRNA gene. With the gram-specific probes based real-time PCR, 35 clinical frequently-isolated strains including 17 gram-positive and 18 gram-negative bacteria were identified correctly with the corresponding gram probe. The blood samples from 512 cases of suspected septicemia, who were hospitalized in our neonatal ward and the NICU and developed clinical signs suggestive of infection, were tested with routine culture and bacterial gram-specific probes based real-time PCR separately. Results The detection limit of the gram-specific probes based real-time PCR assay was 10 CFU of the bacteria. The 35 isolates could be detected and classified correctly by gram-specific probes based real-time PCR. The PCR results were all negative for Cytomegalo virus, EB virus, hepatitis B virus, Cryptococcns neoformans, candida albican, human genomic DNA and negative control. The gram-specific probes based real-time PCR appeared to be quite specific. For 512 blood specimens from the patients with suspicious neonatal sepsis, the positive rate of the gram-specific probes based real-time PCR array was 8.20% (42/512,), which is significantly higher than that of blood culture (32/512, 6.25%) (χ2=8.10, P<0.01). When blood culture was used as a standard, the sensitivity of the gram-specific probes based real-time PCR was 100%. The specificity was 97.92% and the accuracy was 98.05%. Canclusions Cram-specific probes based real-time PCR with universal primers and gram-specific probes are developed. This study suggests that the bacterial gram-specific probes based real-time PCR are very useful for the rapid and accurate diagnosis of bacterial infection.
