Objective To investigate the clinical features and the imaging examination changes of bacterial meningitis in children of different age groups,and to offer theoretical basis for the clinic diagnosis of bacterial meningi-tis. Methods The sick children with bacterial meningitis treated in Guangzhou Women and Children′s Medical Center from January 2011 to June 2013,were recruited and divided into three groups according to the age,including newborns group,infants group and more than 1 year group. Eighty-nine cases with purulent meningitis were recruited,included 58 males and 31 females. Among them,there were 34 cases in the newborns group,41 cases in the infants group and 14 ca-ses in the more than 1-year group. The information on the clinical features,laboratory examination and the imaging ex-amination were summarized and analyzed,and were compared among the 3 groups. Results (1)Among them,54 cases with high fever,44 cases with respiratory symptoms,12 cases with alimentary tract symptoms. (2)The major neurologi-cal features included convulsions(44 cases,49. 4%),fatigue(36 cases,40. 4%),vomiting(21 cases,23. 6%),cervical rigidity(9 cases,10. 1%),fontanel full(7 cases,7. 9%),headache(6 cases,6. 7%),limb paralysis(5 cases,5. 6%). The percentage of high fever,vomiting,headache,cervical rigidity in the more than 1 year group were significantly more than those of the newborns group and the infants group(χ2=10. 093,12. 063,34. 466,7. 177,all P<0. 05). (3)Among them,whitebloodcell(WBC)accountswerefrom2.20to60.60×109/L,themeanwas(16.49±10.37)×109/L.Hy-persensitive C-reaction protein concentration in blood was 4. 00 to 376. 53 g/L,the mean was (131. 07±86. 91) g/L. In cerebrospinal fluid(CSF),WBC accounts were from 1 to 21 800×106/L,the mean was (910. 05±274. 07)×106/L, the glucose concentration from 0. 00 to 4. 50 mmol/L,the mean (1. 72±1. 03)mmol/L,the protein concentration from 0. 42 to 4. 89 g/L,the mean was(1. 64±1. 03)g/L. In 40 cases with atypical CSF change, 23 cases with CSF glucose ratio(CSF glucose/blood glucose) less than or equal to 0. 4, and 15 cases with blood cultures positive. (4)The image examination showed magnetic resonance imaging( MRI) abnormalities in 51/75 cases,computerized tomography( CT) scan abnormalities in 15/30 cases. The percentage of convulsions,the brain MRI abnormalities and the MRI display rate of bacterial meningitis in the infants group were significantly more than those of the newborns group and the more than 1 year group(χ2=11. 768,9. 047,7. 674,all P<0. 05). The display rate of meningitis and subdural hydroma by the brain MRI were significantly more than those of the head CT scan(χ2=7. 430,5. 291,all P<0. 05). Conclusions Be-cause of the atypical clinical features of bacterial meningitis in newborn and infant, lumber puncture should be per-formed in all doubtful cases who had a fever and/or seizure. CSF glucose less than or equal to 0. 4 of simultaneously ob-tained blood glucose value,the enhanced MRI sequence or blood cultures were useful for the likelihood of meningitis,if CSF chemistries and cytology vary atypically. The MRI sequence can significantly mostly improve the display rate of bacterial meningitis than the enhance CT.

Objective To improve the understanding of cutaneous Mycobacterium haemophilum infection.Methods Clinical and laboratory data were collected from two patients with cutaneous Mycobacterium haemophilum infection.The clinical and histopathologic manifestations, etiology and treatment of cutaneous Mycobacterium haemophilum infection were analyzed.Results The two patients were both immunocompromised.Lesions, which occurred after trauma in both the patients, began as well-marginated subcutaneous nodules, and then gradually progressed into ulceration with crusting and abscess formation.Histopathological examination revealed epithelial cell granuloma or histiocytic infiltrate in the dermis, as well as focal necrosis and neutrophil abscesses.Acid-fast staining showed abundant bacilli in tissues.These bacilli only grew in iron-containing medium, and were finally identified as Mycobacterium haemophilum by PCR and sequencing.According to the result of antimicrobial sensitivity testing, both the patients were treated with rifampicin, clarithromycin and moxifloxacin.Three months later, the condition was improved in both of them.Conclusions Mycobacterium haemophilum infection occurs most frequently in immunocompromised populations after trauma, manifests as subcutaneous nodules and abscesses with histopathological changes consistent with infectious granuloma.Molecular biological approaches are reliable for the identification of Mycobacterium haemophilum.

BACKGROUND: Pathophysiological mechanism of local microenvironment is complex after central nerve injury; especially,both inflammatory reaction at an acute phase and formation of secondary glial scar have tremendous effects on effective regeneration of axon, regeneration and arrangement of local nerve cells, proliferation and migration of local stem cells;therefore, it becomes a basic reason for blocking nerve repair in an early period. Thus, how to effectively resist inflammatory factors in injured region at an acute phase and how to optimize microenvironment of neural regeneration are the most important strategies for repairing spinal cord injury in recent years.OBJECTIVE: To design, establish and screen the best expression of interleukin-6 receptor (IL-6R) α to inhibit shRNA adenovirus expression vector by using spinal cord injury models.DESIGN: Duplicative measurement study.SETTING: Department of Spine Surgery, the Second People's Hospital of Shenzhen.MATERIALS: A total of 40 healthy Wistar rats, either gender, 8-10 weeks old, were selected in this study. Rabbit-anti-rat glial fibrillary acidic protein (GFAP) antibody Ⅰ was provided by Santa Cruz Compan; siRNA eukaryon expression plasmid pGenesil (cohtaining green fluorescent expression system) was provided by Wuhan Jingsai Bioengineering Company.METHODS: The experiment was carried out in ImmuneOpening Laboratory, Basic Medical Faulty, Tongji Medical College, Huazhong University of Science and Technology, and Medica Laboratory Center, the Second People's Hospital of Shenzhen in November 2006. Three pairs of shRNA template which composed of 19 bp reverse repeated motif of IL-6 receptor (IL-6R) α target sequence with 9 bp spacer were designed and synthesized, then the recombinant adenovirus expression vectors with green fluorescence protein were constructed in vitro respectively. The acute spinal cord injury models were completed, and the adenovirus recombinants were regionally injected post 12 hours after spinal cord injury;in addition, the inhibitory effect of RNA interference (RNAi) on expression of IL-6R in local region after spinal cord injury were detected by using real-time fluorescence quantitative reverse transcription polymerase chain reaction (RT-PCR) and Western blot so as to screen adenovirus expression vector which had the best inhibitory effect on expression of IL-6R.MAIN OUTCOME MEASURES: Inhibitory effect of RNAi on expressions of IL-6R RNA and protein in local region after spinal cord injury.RESULTS: Sequence analysis showed that IL-6R-shRNA recombinant adenovirus expression vector was successfully constructed, and optimal IL-6R-shRNA recombinant adenovirus expression vector was screened by using real-time fluorescence quantitative RT-PCR and Western blot. The IL-6R expressions were 49% and 56% at the levels of mRNA and protein, respectively.CONCLUSION: The IL-6R--shRNA recombinant adenovirus expression vector is successfully constructed and screened.The gene expression of IL-6R can be highly inhibited after acute spinal cord injury.

objective To explore the indication of mechanical ventilation and evaluate the effects of mechanical ventilation with the least delay on the Severe cases of hand-foot-mouth disease(HFMD).Methods Retrospective cohort study was conducted among the severe HFMD cases(n=66)admitted to pediatric intensive care unit(PICU)between July 2008 and september 2009.Sixty-six cases were divided into two groups:42 cases(group A,July 5 to October 31,2008)were ventilated with the common mechanical ventilation,24 cases(group B,April 21 to september 30,2009)were ventilated at least delay when the symptoms of neurogenic pulmonary edema appeared.Then the diffcrences on the survival rate and the mortality in the group A and group B were investigated.Results Twenty out of 42 patients died(47.6%),eighteen were cured(42.6%) and four showed improved signs(9.5%)in group A.Twenty-two out of 24 patients were cured(91.7%),two showed improved signs(8.3%)and no death in group B.The clinical effect of group B was much better tllan group A(P<0.001).Conclusion Early mechanical ventilation would improve the survival rate and decrease the mortality of severe hand-foot-mouth disease.
