Objective To evaluate the results of the treatment and prevention measures for pathological dislocation of the hip following septic arthritis in the newborns. Methods Twenty cases undergone open reduction were studied restropectively. In addition, greater trochanterplasty was penformed in 15 cases, acetabularplasty in 14 cases, greater and lesser trochanterplasty in 2 cases. Rusults A successful rate of reduction achieved in 90％ of the patients; however, central reduction was achieved in only 38.8％ . 20 patients were followed-up for 6 months to 12 years. The stability and motility of the hip gradually improved in majority of the patients. The cases with severe destruction followed by absence of femoral head and neck had unsatisfactory results. Shortening deformity were found in six cases, and subluxation, dislocation, rigidity of the hip in one case each. Conclusion The greater trochanterplasty had a good result for reduction and maintaining the position. Early diagnosis and early open drainage were key measures for prevention of pathological dislocation of the hip resulting from the acute septic arthritis in the newborn.

Objective To explore the effect of meropenem on the treatment of children with severe infection and the effect on the level of PCT.MethodsThe clinical data of patients with infectious diseases treated in our hospital from December 2013 to February 2016 were retrospectively analyzed.According to the anti infective drugs were divided into control group and observation group, the control group was given routine antibiotic treatment, the observation group was given meropenem treatment.The treatment effect of the two groups were observed, the difference of serum PCT, cytokine level and blood gas indexes before and after treatment in the two groups were compared, correlation analysis with PCT level and serum levels of inflammatory cytokines and blood indexes of severe infection.ResultsIn the control group, 50 cases were successful, the observation group was successful in the treatment of the patients, there were no significant differences in the success rate between the two groups.Two groups of patients before treatment PCT and inflammatory cytokines level no difference, after treatment, the observation group PCT, IL-18, IL-6 and hs-CRP levels were lower than the control group;Two groups of children before treatment blood gas index no difference, after treatment, the observation group SpO2 level higher than the control group, P ETCO2 level was lower than the control group.PCT levels in children with severe infection were positively correlated with IL-18, IL-6, hs-CRP and P ETCO2 levels and negatively correlated with SpO2 levels.ConclusionMeropenem has better therapeutic effect in the treatment of children with severe infection, can significantly reduce the serum PCT level, has the value of clinical application.

BACKGROUND:Currently, transplantation of bone marrow mesenchymal stem cel s into the spinal cord is very limited to the recovery of animals fol owing spinal cord injury. Methylcobalamin is a common drug for the treatment of neurological diseases and injuries, but its effects on bone marrow mesenchymal stem cel s are unclear. OBJECTIVE:To study the feasibility of bone marrow mesenchymal stem cel s differentiating into neuron-like cel s induced by methylcobalamin in vitro and to observe the cel viability and proliferation of differentiated cel s. Methods:Rat bone marrow mesenchymal stem cel s were isolated, cultured and purified by density gradient centrifugation and adherent culture. The fourth to fifth generation of bone marrow mesenchymal stem cel s were treated for 24, 48 and 72 hours with different concentrations (25, 50 and 100 mg/L) of methylcobalamin. The morphological changes and cel growth were continuously observed under an inverted phase constract microscope. The viability of induced cel s was detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. The expressions of Nestin and neuron-specific enolase were identified by reverse transcription PCR and western blot. RESULTS AND CONCLUSION:Most of bone marrow mesenchymal stem cel s could differentiate into neuron-like cel s after induction with methylcobalamin. The expressions of Nestin and neuron-specific enolase were up-regulated after 48 hours of methylcobalamin treatment at different concentrations, especial y after treatment with 100 mg/L methylcobalamin. Similarly, the expressions of Nestin and neuron-specific enolase could be increased significantly after 100 mg/L methylcobalamin treatment for 24, 48 and 72 hours, especial y for 72 hours. It is indicated that methylcobalamin can induce bone marrow mesenchymal stem cel s differentiating into neuron-like cel s, and the optimal concentration of methylcobalamin is 100 mg/L.

Objective To explore the clinical characteristics of infratentorial primary angiitis in central nervous system (PACNS).Methods A total of 5 cases diagnosed as infratentorial PACNS in the neurology department of Navy General Hospital of PLA in 2015 were enrolled in the study.The clinical,imaging and pathological data were collected and analyzed.Results All the 5 cases were male with the median onset age of thirty-four.Five cases presented with dizziness,two with headache,three with walking unstable,two with facial numbness and one with dysarthria.Rising pressure of cerebrospinal fluid (CSF) (190-245 cmH2O,1 cmH2O =0.098 kPa) was found in 4 cases by the lumbar puncture,mildly increased number of leukocyte in 2 cases [(12-28) × 106/L],increased CSF protein in 3 cases(540-979 mg/L) and increased IgG index in 3 cases (0.84-1.45).Pons lesions were revealed by magnetic resonance imaging(MRI) in 4 cases,brachium pontis lesions in 2 cases,cerebellum lesions in 2 cases,one with midbrain lesion in 1 case,unilateral lesions in 4 cases and bilateral lesion in 1 case.Different degree of edema and mass effect were shown in all lesions by MRI.Patch like enhancement was found by contrast MRI in 5 cases and meningeal enhancement in 2 cases.Elevation of choline (Cho) peak was found by magnetic resonance spectroscopy (MRS) in 4 cases,reduction of N-acetyl aspartate (NAA) peak in 3 cases,appearance of lactate peak in 1 case and lipid peak in another case.Arterial spin labeling (ASL) was performed in 4 cases and no hyperperfusion was found.Susceptibility weighted imaging(SWI) was performed in 3 cases and microhemorrhage in the lesions was found in 2 cases and normal in 1 case.Magnetic resonance arteriography(MRA) was performed in 1 case and no stenosis was found.Digital subtraction arteriography(DSA) was performed in 1 case and multiple stenosis of the intracranial arteries was showed.Two cases had taken the stereotactic brain biopsy and the histopathologic diagnosis was angiitis.Five cases were treated with methylprednisolone and cyclophosphamide was added on in 1 case.Good prognosis was found in all cases.Conclusions Infratentorial PACNS mostly attacks middle-aged males.The lesions tend to locate in unilateral pons,brachium pontis,cerebellum and midbrain.Hemorrhage or microhemorrhage in lesions is often found by SWI and no hyperperfusion is shown by ASL,which would be useful to distinguish PACNS from malignant tumors.Given the limitations of brain biopsy in clinical practice,clinical and imaging features would be helpful to diagnose PACNS.

Objective To analyze the relationship of penA, ponA, porB and mtrR gene mutations with the reduced sensitivity to ceftriaxone in N.gonorrhoeae isolates from Shenzhen city.Methods A total of 296 clinical isolates of N.gonorrhoeae were collected in Shenzhen city from 2009 to 2011.The agar dilution method was used to estimate the sensitivity of these N.gonorrhoeae to ceftriaxone.Totally, 53 strains with reduced sensitivity to ceftriaxone (minimum inhibitory concentration (MIC): 0.06-0.50 μg/ml) were identified, and 53 strains with high sensitivity to ceftriaxone were randomly selected from the remaining strains and served as the control group.PCR was performed to amplify the penA, ponA,porB and mtrR genes from the 106 isolates followed DNA sequencing.Results The mosaic structure of the penicillinbinding protein 2 (PBP2) gene (penA gene) was found in only one isolate with a ceftriaxone MIC of 0.125 0 μg/ml.Amino acid sequence analysis of the remaining 105 isolates yielded 16 different amino acid patterns.The MICs of ceftriaxone were relatively high (0.062 5 μg/ml) in N.gonorrhoeae strains harboring the amino acid patterns ⅩⅢ, ⅩⅧ or ⅩⅩⅩⅧ,but relatively low (0.008 0 μg/ml) in those harboring the amino acid pattern Ⅱ.No significant differences were observed in the frequency of mtrR, porB or ponA gene mutations between N.gonorrhoeae isolates with reduced sensitivity to ceftriaxone and those with high sensitivity (all P ＞ 0.05).Conclusions The mosaic structure of PBP2 may be not the primary reason for reduced sensitivity of Neisseria gonorrhoeae to ceftriaxone in Shenzhen, while different amino acid patterns produced by various mutations in amino acid residues at positions 500-580 in the non-mosaic PBP2, together with mtrR, porB and ponA mutations, may play more important roles in the reduced sensitivity.
