Multiple organ dysfunction syndrome(MODS),a hot topic worldwide,has made rapid progress with nigh mortality.MODS in pediatrics versus MODS in adults are similar but different.Due to special age-related physiological characteristics.It is difficult to carry out randomized controlled clinical study compared with adults.Diagnosis and treatment of pediatric MODS can only be obtained with reference to adult MODS.This study reviews on the epidemiology,clinical scoring system,pathogenesis,clinical features and treatment of MODS in pediatrics.

Objective To investigate the liver damage caused by single high-dose intake of ethanol in mice. Methods Twenty-four male Kunming mice were randomized into 2 groups. The mice in ethanol group were treated with single dose of ethanol (50%,V/V,12 ml/kg),while the control mice received distilled water. The serum biochemical indices were determined 16 h after ethanol exposure. The hepatic triglyceride (TG) and free fatty acid (FFA) levels and the histological changes were examined to evaluate the fat accumulation,while the Ca2+-induced mitochondrial permeability transition (MPT) was detected for the mitochondrial function assay. The liver and mitochondrial malondialdehyde (MDA) and glutathione (GSH) levels were determined to assess the lipid peroxidation level. The activities and the protein expression of the CYP2E1,1A2,3A were determined. Results Slow response,ataxia and righting reflex disappearance were gradually emerged,which disappeared at about 3 h later. Compared with the control group,the liver index,the serum ALT and AST activities,the hepatic TG,FFA,and MDA levels,and the activity and protein level of the CYP2E1 significantly increased,while the liver GSH level significantly decreased (P0.05). In addition,A540 of ethanol group was higher than that of control group (P

Objective To study the immune regulatory effect of natural killer cell(NKT) in the early stage of murine liver injury induced by type 5 adenovirus(Ad5). Methods Animal models were con-structed by injected C57BL/6 mice with 1.5×109-3×109 PFU Ad5 into the tail vein. Liver injury of mouse at day 0, 1, 2, 3, 4, 5 after infection was determined by HE staining and serum ALT/AST(alanine amin-otransferase/aspartate aminotransferase) level. Flow cytometry analysis was used to measure the proportion of lymphocytes, expression of Fas/FasL on the surface of NKT cells and level of IL-4, IFN-γ/in NKT cell plasma in the infected mouse liver. RT-PCR was applied to semi-quantify the chemokines and their receptors mRNA in infected mouse liver. Results NKT cells of mouse increased significantly at day 1 after infected with high titer Ads(3×109 PFU), expression of FasL on NKT cell and plasma IL-4, IFN-γ/level in NKT cells were also up-regulated, hence the obviously infiltration of lymphocytes in routine liver. Comparing with high titer Ads infection, low titer Ads infection (1.5×109 PFU) lead to little change of NKT cell proper-tion, and fewer infiltration of lymphocytes in murine liver. Hepatic chemokine RANTES, 1P-10, and MIP-1β mRNA expression in C57BL/6 was up-regulated 2 d after intravenous administration of 3×109 PFU Ad5. Corresponding chemokine receptor CCR5, CCR1, CXCR3 mRNA expression was up-regulated 3 d after in-fection. Conclusion NKT cells play an important role in lymphocytes recruitment into the liver of mouse in-fected with AdS, which may relate to up-regulatio of the plasma IL-4, IFN-γ level and expression of FasL of NKT cells, therefore facilitating the production of chemokines, e.g. IP-10 and Mig.

Objective To analyze the relationship of the lateral angulation with the incision level after anterior approach operation for thoracolumbar fractures by evaluating the Cobb' s angle at different approach levels.Methods A retrospective study was done on 154 patients with thoracolumbar fractures treated consecutively with anterior operation from May 2004 to January 2008.The preoperative,postoperative and follow-up angle of coronal Cobb and the postoperative angle between screws and endplates on the anteroposterior radiograph were measured.According to the relationship between the injury vertebrae and the incision level,the patients were divided into two groups,ie,incision level ≥2 vertebrae group and incision level ≤ 1 vertebra group.Results All patients were followed up for 6-47 months(mean 37 months),which showed significant postoperative lateral angulation(P ＜ 0.01)especially at follow-up (P ＞ 0.05).The coronal Cobb' s angle showed insignificant difference before operation between two groups but it was increased after operation and during the follow-up(P ＜0.01).The screws A or B were more parallel to the endplate in two groups(P ＜ 0.01),while the parallel of the screws C or D to the endplate showed no statistical difference(P ＞ 0.05).Conclusions Compared with the operation with incision level ≥2 vertebrae,the operation with incision level ≤ 1 vertebra can more easily induce postoperative lateral angulation and exert a significant impact on implantation orientation of the vertebral screws A and B,which may indirectly lead to postoperative lateral angulation.

Objective To evaluate cause,treatment and prevention of esophageal fistula caused by anterior cervical spine surgery.Methods Between January 2004 and December 2011,2348 patients underwent anterior cervical spine surgery.Among them,5 patients suffered from esophageal fistula owing to operation,including 3 males and 2 females,with an average age of 34 years (range,14 to 48 years).The diagnosis of these patients included 3 cases of cervi(c)al injury,1 case of cervical spondylosis and 1 case of cervical tuberculosis.There was 1 patient whose esophageal injury was founded during the surgery,and that was directly repaired.For another 4 patients,esophageal fistulas were founded after operation; one case underwent debridement and orificium fistulae repair; one case only underwent debridement; one case underwent debridement and second-stage removal of hardware; and one case underwent debridement and second-stage removal of hardware and esophageal repair with sternocleidomastoid flap.Postoperative treatment included esophageal rest,enteral nutrition,wound drainage,and antibiotic administration.Methylene blue was used to evaluate status of orificium fistulae.Results All patients with esophageal fistula were cured 9 to 61 weeks after treatment,and oral intake was achieved.They were followed up for 6-48 months.There was no recurrence of esophageal fistula,cervical instability and infectious spondylitis in any ease.All patients were satisfied with swallowing function and outcome of cervical spine diseases.The Frankel grade was improved averagely one grade in patients with cervical injury,and the JOA score was improved from preoperative 9 points to postoperative 15 points in patients with cervical spondylosis.Conclusion Successful management of esophageal fistula caused by anterior cervical spinal surgery depends on primary closure of the perforation with or without muscle flaps,surgical drainage,esophageal rest and nutrition support,and removal of hardware if necessary.Prevention consists of the careful operation and gentle tissue handling.

Objective To analyze the clinic characteristics, lifetime and prognostic factors of young female breast cancer patients. MethodsClinical data of 155 patients under 35 years of age with breast cancer were retrospectively reviewed and followed up.ResultsThe positive rate of hormone receptors was 61.6 % (77/125) in all cases who had been detected receptor status. The median survival time in hormone receptors positive and negative group were 119.0 and 51.3 months (P＜0.01), and 5-year survival rates were 68 % and 33 %, respectively. For patients who had been treated with adjuvant tamoxifen (47.1%), the median survival time was 182 months which longer than without tamoxifen (P ＜0.05). The median disease-free survival time and median survival time were 24 and 91 months in all cases. The overall 3-, 5- and 10-year survival rates were 79 %, 60 % and 51%, respectively. Multifactor analysis with the COX model indicated that tumor size, axillary metastatic status, tamoxifen treatment and overexpression of Her-2 were independent prognostic factors. While clinic stage and hormone receptors status might be referenced prognostic factors. ConclusionYoung women breast cancer patient may have good prognosis if multimodality treatment is conducted. Tumor size, axillary metastatic status, adjuvant endocrine therapy and overexpression of Her-2 are independent prognostic factors.
