Objective To investigate the clinical features of invasive pneumococcal disease (IPD) and the antimicrobial susceptibility of invasive Streptococcus pneumoniae (Sp). Methods The clinical features of 54 children with IPD and the antimi-crobial susceptibility of 54 invasive Sp isolates were retrospectively analyzed from 2009 to 2012. Results The ratio of boys to girls in IPD was 1.35:1. Most of the children with IPD were within 2 years old. Few of the children had the onset in summer. Most of the children were diagnosed with septicemia, followed by meningitis. All of the children had middle or high fever. Forty-four children had an increased white blood cell count and 42 children had an increased C-reactive protein.β-lactam antibiotics was most frequently used in clinics, followed by vancomycin. Most of invasive Sp were resistant to penicillin. Multiple drug resis-tance was common in invasive Sp. Conclusions The incidence of IPD has seasonal difference. The clinical manifestations of IPD are diverse, with septicemia being the most common. The resistant rate to penicillin is high in invasive Sp.

Objective To outline the classification of spinal tuberculosis based on MRI findings (Southern Medical University classification,SMU classification) and explore its use in the diagnosis,surgical protocols.Methods The MRI data from 230 cases with spinal tuberculosis were analyzed retrospectively.Our classification system was based on clinical and radiological criteria (abscess formation,disc degeneration,vertebral collapse,kyphosis,sagittal index,instability and neurological problems).The surgical strategies were made according with this classification.Results Two hundred and thirty cases with spinal tuberculosis were classified into the 5 types.There were signal change type (type Ⅰ) in 28 cases,abscess formation type (type Ⅱ) in 39,vertebral collapse type (type Ⅲ) in 78,canal compression type (type Ⅳ) in 46 and kyphosis type (type Ⅴ) in 39 respectively.In type I lesion,25 patients had been followed up.Twenty patients were treated medically.Recurrence of tuberculosis was found in 2 cases.Surgical meticulous debridements were done in 5 cases without recurrence.In type Ⅱa lesion,6 patients were treated medically.The other 6 patients underwent surgical meticulous debridement with recurrence occurred in one patient.There was no difference between medical and surgical treatment regarding outcomes in patients with type Ⅰ and Ⅱa lesion.In type Ⅱb-Ⅴ,surgical treatments were carried out according to the pathological changes.There was no difference between medical and surgical treatment regarding outcomes in the patients with type Ⅱb-Ⅴ.Conclusion The SMU classification helps in differentiating the various manifestations of spinal tuberculosis and appears to correlate with the surgical treatment of spinal tuberculosis.We believe that this new classification system can be used as a practical guide in the treatment of spinal tuberculosis.

Objective To investigate the anti-inflammatory activity of the main active ingredients in the dried stem bark of Daphne giraldii Nitsche.Methods Severialchemical compounds like vladinol D, pinoresinol, daphneticin, daphnoretin, daphnetin, giraloid A and giraldoid B were isolated from the stem barks. The CCK-8 experiemnts were analyzed for the cytotoxicity study. The cells were divided into the control group, the model group and the treatment group according to random number table method. The control group and the model group were added with 50μl culture medium. Moreover, treatment group was added with different concentrations (50.00, 25.00, 12.50, 6.25, 3.12μg/ml) of the solutions of giraloid A, giraldoid B and daphneticin. Then, RAW264.7 cells were treated with 50μl LPS (4μg/ml) for 24 h in the model group and treatment group. Griess reagent was used to determine the amount of NO release, and the secretion of TNF-α was detected by ELISA kit.Results Cytotoxicity test indicated that giraldoid A (50.00μg/ml), giraldoid B (50.00μg/ml) and daphneticin (50.00μg/ml) showed noobvious cytotoxicity. Giraldoid B (12.50, 25.00, 50.00μg/ml) could inhibit the production of NO (271.86% ± 20.92%, 256.48% ± 20.92%, 199.31% ± 15.16%vs.358.62% ± 28.64%) and  TNF-α (647.87% ±115.79%, 618.42% ± 87.52%, 588.33% ± 87.94%vs. 1035.06% ± 58.29%) in RAW264.7 induced by LPS compared with the model group. Giraldoid A (25, 50μg/ml) could inhibit the production of NO (234.99% ± 34.28%, 167.36% ± 25.76% vs.358.62%±28.64%) and TNF-α (691.76% ± 60.37%, 534.01% ± 41.60% vs. 1035.06% ± 58.29%) in RAW264.7 induced by LPS compared with the model group. Daphneticin (12.5, 25, 50μg/ml) could inhibit the production of NO (283.89% ± 36.69%, 243.08% ± 48.19%, 225.92% ± 33.67% vs.358.62% ± 28.64%) and TNF-α (713.77% ± 121.96%, 670.62% ± 18.70% vs. 1035.06% ± 58.29%) in RAW264.7 induced by LPS compared with the model group.Conclusions Giraldoid A, giraldoid B and daphneticin exhi bited anti-inflammatory effect through inhibiting the release of NO and the production of TNF-α in RAW264.7 induced by LPS.

OBJECTIVE To analyze the major reasons of wound infection after external fixator application and then introduce management measures to prevent following wound infections. METHODS Totally 542 patients adopting external fixators between May 2005 and May 2007 were retrospectively reviewed. All the external fixator-related infections were inspected and the excretions from these infected wounds were collected to perform bacterial culturing. RESULTS The total infection rate of these 542 patients after external fixator application was 2.77%. Among them, six were infected with the bacteria in distraction osteogenesis group and the infection rate was 8.82%; three were infected in bone un-union and bone defect group and the infection rate was 5.36%; whilest the common fracture-fixing group got the lowest infection rate of 0.39%. CONCLUSIONS Wire-crossing positions are the most frequently infected sites after external fixation and the drug-resisted bacteria are the most commonly detected pathogens. Thus, increasing the stability of fixators, enhancing the infection supervision of operation environment, draining the wound thoroughly and using antibiotics rationally are the most effective managing measures to prevent external fixator-related infections in orthopedics.
