BACKGROUNDCervicothoracic junction spinal tuberculosis (CJST) in children is uncommon, especially when accompanied by a huge abscess. However, its consequences can be severe. Because of the special anatomic location of the cervicothoracic junction, surgical treatment is difficult and rarely reported. The aim of this clinical study was to assess the effectiveness of combined anterior and posterior approaches for focal debridement, decompression, allografting and anterior instrumentation in the treatment of CJST in children.

METHODSTen pediatric CJST patients underwent focal debridement and cord decompression through combined anterior and posterior approaches. Then an appropriate allograft and titanium plate were applied to reconstruct the spine. The patients were asked to wear head-neck-chest braces for six months and received regular anti-tubercular drugs therapy for 12 months.

RESULTSThe patients were followed-up for an average of 26 months (range, 15-32 months). There was no recurrent tuberculous infection. The bone grafts incorporated well and the instrumentation was stable. Cervical and thoracic kyphosis was successfully corrected from 40° (range, 30-52°) before the operation to 18° (range, 12-26°) post-operation. Neurological function was improved in all patients.

CONCLUSIONSCombined anterior and posterior approaches for focal debridement, decompression, bone allografting and anterior instrumentation provided an effective means of treatment in children of CJST with a huge abscess in the posterior part of the vertebral body.

Background Noninvasive positive pressure ventilation (NIPPV) has been proposed to shorten the duration of mechanical ventilation in intubated patients,especially those who fail initial weaning from invasive mechanical ventilation (IMV).However,there are also some discrepancies in terms of weaning success or failure,incidence of re-intubation,complications observed during study and patient outcomes.The primary objective of this update was to specifically investigate the role of NIPPV on facilitating weaning and avoiding re-intubation in patients intubated for different etiologies of acute respiratory failure,by comparing with conventional invasive weaning approach.Methods We searched randomized controlled trials (RCTs) comparing noninvasive weaning of early extubation and immediate application of NIPPV with invasive weaning in intubated patients from PubMed,Embase,Cochrane Central Register of Controlled Trials,Web of Knowledge and Springerlink databases.Records from conference proceedings and reference lists of relevant studies were also identified.Results A total of 11 RCTs with 623 patients were available for the present analysis.Compared with IMV,NIPPV significantly increased weaning success rates (odds ratio (OR):2.50,95％ confidence interval (C/):1.46-4.30,P=0.0009),decreased mortality (OR:0.39,95％ CI:0.20-0.75,P=0.005),and reduced the incidence of ventilator associated pneumonia (VAP) (OR:0.17,95％ CI:0.08-0.37,P ＜0.00001) and complications (OR:0.22,95％ CI:0.07-0.72,P=0.01).However,effect of NIPPV on re-intubation did not reach statistical difference (OR:0.61,95％ CI:0.33-1.11,P=0.11).Conclusions Early extubation and immediate application of NIPPV is superior to conventional invasive weaning approach in increasing weaning success rates,decreasing the risk of mortality and reducing the incidence of VAP and complications,in patients who need weaning from IMV.However,it should be applied with caution,as there is insufficient beneficial evidence to definitely recommend it in terms of avoiding re-intubation.

This study was purposed to investigate the relationship between tissue factor associated platelet microparticles and thrombosis of patients with lymphoma by detecting the density of platelet microparticles and the tissue factor coagulative activity, and to evaluate the possibility of tissue factor coagulative activity for predication of thrombosis in lymphoma patients. This study was divided into 3 groups: A group including 50 healthy persons who did not take any drugs and had no hypercoagulation diseases; B group including 50 cases of lymphoma without thrombosis, and C group including 8 cases of lymphoma with thrombosis. The plasma was isolated from venous blood by centrifugation. The density of platelet microparticles was detected by flow cytometry; the tissue factor coagulative activity of plasma was measured by chromogenic substrate. The results indicated that compared with group A, the density of platelet microparticles increased in group B. Compared with group B, group C had significantly higher density of platelet microparticles and tissue factor coagulative activity (P < 0.01). It is concluded that the density of tissue factor associated platelet microparticle has predictive value for lymphoma with thrombosis, which can be used as target of clinical test.

OBJECTIVETo summarize the histological and clinical characteristics of 40 cases with Burkitt's and Burkitt-like lymphoma in children, to evaluate the effects of treatment with international regimen, and to explore the treatment-related complications and prognostic factors.

METHODSForty patients with Burkitt's and Burkitt-like lymphoma were registered in Beijing Children Hospital from Feb 2003 to Apr 2006. The diagnosis was confirmed by histology and immunohistochemistry of biopsy, and clinical staging by the examination of imaging, cerebrospinal fluid and bone marrow based on St. Jude system. Intensive, short-term chemotherapy witch was modified from LMB89 protocol was given to the patients.

RESULTSOf the 40 patients, 30 were diagnosed as Burkitt's lymphoma (BL) and 10 as Burkitt-like lymphoma (BLL). Antibody against Epstein-Barr virus (EBV-Ab) was positive in 19 cases at diagnosis, only 7 of the patients were positive for EBER. Thirty-three of the cases were male and 7 female (M:F = 4.7:1); the median age was 6 years 9 months. The most frequently seen clinical characteristics were abdominal masses and surgical abdomen. Nine cases were at stage I - II and 31 cases at stage III - IV at diagnosis; CNS was involved in 4 cases and bone marrow in 2 cases. The courses of treatment were approximately 2 - 8 months. All the patients were followed up, the median follow-up period was 22.6 months. After chemotherapy, 35 patients (88.7%) were still alive during the one-year follow-up. The 3-year event-free survival (EFS) rate was 81.8%. Major toxicity was myelosuppression and mucositis. Stage III to IV of myelosuppression occurred in the most patients with unresected tumor and CNS-involvement. Of 5 patients who died, 2 died of infection, 2 died of lymphoma progression during chemotherapy, and 1 died of relapse.

CONCLUSIONBurkitt's and Burkitt-like lymphoma are the most common NHL in children with rapid clinical process. Outcome was greatly improved by current intensive, short-term chemotherapy regimen, the 3-year EFS was 81.8% including the patients who were in advanced stage. Childhood lymphoma with short clinical history, stage IV and residual disease after 3 months of therapy are associated with poor prognosis.

To explore the new method of discriminating Astragali Radix and Hedysari Radix by using PCR amplification of specific alleles, 30 samples of the different Astragali Radix materials and 28 samples of Hedysari Radix were collected. The total DNA of all samples were extracted, trnL-trnF sequence from Astragali Radix and Hedysari Radix was amplified by PCR and sequenced unidirectionally. These sequences were aligned by using Clustul W. Primer was designed and the PCR reaction systems including annealing temperature, dNTP, etc were optimized. All samples were amplified by PCR with specific primer, DNA from Astragali Radix would be amplified 136 bp, whereas PCR products from all of Hedysari Radix were 323 bp. This method can detect 10% of intentional Hedysari Radix DNA into Astragali Radix. PCR amplification of alleles can be used to identify Astragali Radix and Hedysari Radix successfully and is an efficient molecular marker for authentication of Astragali Radix and Hedysari Radix.

OBJECTIVETo construct luxS mutant aften luxS gene of Streptococcus mutans (S. mutans) was knocked out, and examine their ability of biofilm formation.

METHODSA recombinant plasmid containing the flanking fragment of luxS of S. mutans was transformed into S. mutans UA159, and selected by brain heart infusion (BHI) agar medium with kanamicin. The luxS mutant further confirmed via polymerase chain reaction (PCR) and the autoinducer-2 (AI-2) bioluminescence assay of Vibrio harveyi (V. harveyi), and ability of luxS mutant and S. mutans UA159 biofilm formation was examined in different phases, in BHI medium with 1% sucrose and 1% glycose by scanning electron microscopy (SEM).

RESULTSLuxS-deficient S. mutans strains were successfully constructed. Compared with S. mutans UA159, the luxS mutant maintained in BHI medium containing 1% sucrose displayed an apparent defect in biofilm formation, while they showed no significant deviation in BHI medium containing 1% glycose.

CONCLUSIONluxS gene in S.mutans can play a role in dental plaque biofilm formation, and the luxS gene is possible to regulate sucrose-dependent biofilm formation.

OBJECTIVETo summarize the clinical features and to evaluate outcomes and to assess therapeutic effects in 34 children and adolescents with Hodgkin lymphoma treated with risk-adapted combination chemotherapy and low-dose, involved-field radiation therapy (IFRT) in China.

METHODFrom January 2003 to April 2009, 34 hospitalized children with Hodgkin lymphoma were enrolled into the BCH-HL 2003 protocol (revised CCG 5942) in our hospital. Pathological samples were reviewed centrally and classified based on the World Health Organization guidelines. Staging was based on clinical evaluation and was defined by the Ann Arbor staging system. The 34 patients were treated according to the different risk factors in three treatment groups (standard, intermediate, and high risk), and received risk-adapted combination chemotherapy and IFRT. All analyses were calculated by the statistical program SPSS.

RESULTOf the 34 Hodgkin lymphoma patients, 28 were male and 6 were female. The median age was 8.7 years (range from 4 years to 15 years) at the time of diagnosis. In terms of clinical presentation, 53% had bulky lymph nodes, 47.1% had more than 4 node regions involved and 44% had "B" symptoms at presentation. The distribution for stage of disease was 0% for Stage I, 21% for Stage II, 35% for Stage III and 44% for Stage IV disease. All patients had classical histology consisting of three different sub-discipline: 22 cases of mixed cellularity (64.7%). In pathological samples of 25 cases there was EBV encoded RNA (EBER) or latent membrane protein (LMP) staining. The overall survival (OS) was 100% and the 5-year event-free survival was 94.1% with a median follow-up of (26.1 ± 16.3) months. Two patients had early relapse after treatment was finished. Organ toxicity was limited to hematological grades III and IV at rates of 40% and 71% respectively.

CONCLUSIONChildhood Hodgkin lymphoma in our study was more frequently seen in male school aged children. Combined-modality therapy using risk-adapted chemotherapy with radiation is effective and well tolerated. The overall prognosis was good.
