Objective To study the etiology,clinical characteristics,electroencenphalography(EEG),mental degree of Lennox-Gastaut syndrome(LGS). Method Retrospectively analyzed etiology,sex,age,seizure types,EEG,mental degree of 54 children diagnosed as LGS. Results The number of male was 36,female was 18,seizure onset from 1 month to 8 years,diagnosing age from 3 months to 11years. The EEG reveals 1.5-2.5 Hz spike-wave discharges and a slow baseline activity. Conclusions LGS is one of the most difficult epilepsys to treat and need frequently more than 2 antiepilepsy drugs. It is characterized by variable etiology,multiple types of intractable seizures, and has enormous detrimental effects on patient′s developmental health.

OBJECTIVETo explore the clinical application of mandibular-driven simultaneous maxillo-mandihular distraction to correct hemifacial microsomia with rapid prototyping technology.
METHODSThe patient' s skull resin model was manufactured with rapid prototyping technology. The osteotomy was designed on skull resin model. According to the preoperative design, the patients underwent Le Fort I osteotomy and mandibular ramus osteotomy. The internal mandible distractor was embedded onto the osteotomy position. The occlusal titanium pin was implanted. Distraction were carried out by mandibular-driven simultaneous maxillo-mandihular distraction 5 days after operation.
RESULTSThe distraction in five patients was complete as designed. No infection and dysosteogenesis happened. The longest distance of distraction was 28 mm, and the shortest distance was 16 mm. The facial asymmetry deformity was significantly improved at the end of distraction. The ocelusal plane of patients obviously improved.
CONCLUSIONSRapid prototyping technology is helpful to design precisely osteotomy before operation. Mandibular-driven simultaneous maxillo-mandibular distraction can correct hemifacial microsomia. It is worth to clinical application.

Abstract?AlM:To evaluate the accuracy and practicability of three - dimensionally preformed Arbeitsgemeinschaft Osteosynthese AO titanium mesh plates for orbital fractures.?METHODS:Forty-seven patients with isolated blow-out orbital fractures were included in this study. Fracture locations were as follows: floor/medial wall ( n = 26, 55%), medial wall ( n = 12, 26%), and floor ( n = 9, 19%) . The floor fractures were exposed by a standard transconjunctival approach, whereas a combined transcaruncular transconjunctival approach was used in patients with medial wall fractures with temporary dissection of inferior oblique muscle. A three -dimensionally preformed AO titanium mesh plate was selected according to the size of the defect previously measured on the preoperative computed tomographic scan examination and fixed at the inferior orbital rim with 2 screws. The accuracy of plate positioning of the reconstructed orbit was assessed on the postoperative computed tomography ( CT) scan. The practicability of clinical use of AO three - dimensionally preformed titanium mesh plates was assessed on the preoperative and postoperative clinical data.?RESULTS: Postoperative orbital CT scan showed an anatomic three- dimensional placement of the orbital mesh plates in all of the patients. All patients had a successful treatment outcome without clinical complications. 40 patients ( 87%) had a successful enophthalmos correction. 25 patients ( 86%) had a successful recovery from diplopia.?CONCLUSlON: Three- dimensionally preformed AO titanium mesh plates for orbital fracture reconstruction results in an accurate anatomic restoration of the bony orbital contour with a high rate of success to correctenophthalmos and diplopia.

Objective To study risk factors associated with predisposition to Lm -ABM in adult patients and to evaluate the clinical features,management and out in this cohort of patients because Listeria monocytogenes (Lm) is the third most common cause of acute community acquired bacterial meningitis (Ac-ABM),after Streptococcus pneumoniae and Neisseria meningitides aetiologies.Methods A descriptive,prospective study carried out in a tertiary grade medical center emergency department in Beijing over a 10 -year period.During the study period,15 patients of Lm- ABM were included.Comparison of episodes of Lm - ABM versus other aetiologies was made.Results Fifteen episodes of Lm - ABM were identified in327 adult Ac - ABM patients.Three cohorts of individuals were vulnerable to Lm - ABM:the elderly ( RR=3.14; 95% CI 1.84-5.35),the immunocompromised (RR =3.34; 95% CI2.08-5.38),and pregnant women ( RR 12.48 ; 95% CI 3.29 ~ 47.39 ).The classic triad of fever,neck stiffness,and altered mental status was present in 40% (6 of 15) Lm - ABM patients.Similarly,40% patients had at least one of cerebrospinal fluid (CSF) samples with features met the criteria of typical bacterial meningitis.The coverage of empirical antimicrobial therapy was microbiologically inadequate for 13 ( 86.7% ) patients.The mortality rate was 33.3% (5 of 15),and 7 (46.7% ) of 15 patients led to an unfavorable outcome ( GOS < 4),both of which were significantly higher than those in other aetiologies of Ac - ABM ( P =0.015P =0.009 respectively). Conclusions Our study showed the elderly,the immunocompromised patients,and pregnant women predisposed to Ac - ABM most likely to be Listeria monocytogenes aetiology.In contrast with similar previous reports, the current study showed that patients with meningitis due to Listeria monocytogenes did not present with atypical clinical features.A high proportion of patients received empirical antimicrobial therapy that did not cover Listeria monocytogenes.Lm - ABM is still a serious disease that leads to high morbidity and mortality rates.With these important caveats in mind,our findings have implications for clinical practice and food safety policy makers.
10.Reactive oxygen species and bone marrow hematopoietic stem cell senescence.
Journal of Experimental Hematology 2012;20(6):1518-1521
Reactive oxygen species (ROS) are bioactive oxygen molecules produced after exposure to exogenous oxidants or endogenously through cellular aerobic metabolism. Hematopoietic stem cells (HSC) are multipotent, self-renewing stem cells residing in hematopoietic tissues. Recent studies show that an abnormal increase in ROS production is associated closely with HSC senescence. Many signaling molecules such as FoxOs, ATM, mTOR, TSC1, Bmi1 and AKT play a significant role in ROS-induced HSC senescence. The roles of p53-p21 and p16-Rb pathways can induce hematopoietic dysfunction and lead to ROS-induced HSC senescence. This review summarizes the recent progress of studies on ROS-induced HSC senescence, and further elaborates the potential signaling molecules and pathways, aiming to provide a new target and thread for clinical treatment.
