Viral encephalitis is a common pediatric infectious disease of the nervous system,the correct diagnosis, treatment and quality control has always been a challenge;America, British, European, Australia had issued guidelines for the diagnosis and treatment of encephalitis in 2008-2015 ,which had important reference value for guiding clinicians dealing with viral encephalitis, this article integrated above guides and introduced the definition, classification, etiology, accessory examination, handling procedures and treatment of viral encephalitis in children, and the quality control program in the diagnosis and treatment of viral encephalitis in children was preliminarily discussed.

Bone remains the predominant site of metastasis in advanced breast cancer. Bone metastases dramatically decrease the quality of life. Moreover, pathologic fractures and other skeletal-related events (SREs) caused by bone metastases could result in higher mortality risk in patients with breast cancer. Palliative radiotherapy is a crucial element in bone metastases treatment. The present review discusses the emerging evidence in bone metastases of breast cancer, focusing on optimized radiotherapy strategies and multidisciplinary management.

Objective To explere the curative effects of L-carnitine on neonates with myocardial injury caused by asphyxia.Methods Ninety-one neonates with myocardial injury caused by asphyxia were randomly divided into L-carnitine treatment group(48 cases) and control group(43 cases).The patients in control group were received routine treatment;the patients in treatment group were given L-carnitine 0.1 g/(kg?d) on the basis of routine treatment for 10 days.Symptoms and physical signs were observed pretreatment and during the time of therapy.Before and after the treatment,serum MB isoenzyme of creatine kinase(CK-MB) and aspartate aminotransferase(AST) were mea-sured with immunosuppression and enzyme rate respectively,and serum albumin and prealbumin were detected with the method of bromcresol green chromatometry and immunoturbidimetry,respectively.Results Clinical effective rate of the treatment group(91.67%)was higher than that of control group(74.42%)(P

Objective To test the reliability and validity of the brief International Classification of Functioning, Disability and Health (ICF) core sets for Chinese stroke patients using Rasch model analysis. Methods The body functions of 38 Chinese stroke patients were measured using the brief ICF core sets. The qualifiers of the 20items were measured by two raters and analyzed using FACETS statistical software. The intra-rater reliability and validity were tested by using the separation index and separation reliability and fit analysis. Results The brief ICF core sets had good internal consistency and reliability (person separation index = 6.02, person separation reliability = 0.94 ) with these Chinese patients. The raters showed significantly different strictness in rating, but their ratings had good internal self-consistency. The construct validity was good for the body functions of the ICF component ( separation index = 10.50, separation reliability = 0.80) , but misfitting and overfitting were found in items b117, b152and b755. Conclusion The body function of the brief ICF core sets has good reliability and validity for Chinese stroke patients. A many-facet Rasch measurement model can provide comprehensive information and has good application prospects for testing the reliability and validity of ICF core sets.

Objective To investigate the results of laparoscopy and small incision splenectomy in the treatment of Idiopathic Thrombocytopenic Purpura (ITP). Methods Under CO2 pneumoperitoneum, laparoscopy and small incision splenectomy was performed in 13 patients . After freeing of the spleen with laparoscopy , we performed a small incision under the left costal margin. The splenic pedicle was 1-igated under direct vision, and the spleen was excised and extracted. Analysis was made of the pre-and post-operative platelet counts, and the complication rate and recovery condition of the patients. Results No complications occurred in the 13 palients, and the effect-iveness of ITP treatment was 100%.Conclusions Laparoscopy and small incision splenectomy is a safe and effective method to treat ITP.

A new, convenient, and rapid method for kinetic measurement of human fibrinolysis was established. The alteration of absorbance (A) in the process of blood coagulation and lyses was automatically scanned and recorded using a UV2000 spectrophotometer connected to a computer. The parameters of human fibrinolysis kinetics were established. Urokinase at 20 U/mL was the optimal concentration used. There was significant difference in fibrinolysis kinetics and plasma plasminogen concentration between 22 normal subjects and 27 patients with acute myeloblastic leukemia (P<0.05 and <0.01 respectively). The coefficience of variation was (5.24+/-1.51)%. This method could also be used to measure the plasma fibrinogen concentration at the same time. It was concluded that this method was stable and was capable of providing dynamic, direct experimental data and multiparemeters for clinicians. It was also valuable in evaluating the anti-and pro-fibrinolytic capcity of patients' plasmas, allowing for monitoring of therapy, choice of drugs and adjustment of drug concentrations.

Objective To establish an expression system of TCRγ9/δ2-Fc protein by baculovirus vector ex-pression system and identify biological function of expressed TCRγ9/δ2-Fc protein. Methods γ9Fc and 82 (OT3) Fc gene fragments were amplified by overlap PCR and inserted into expression vector pBACp10ph. The recombinant plasmid pBACp10ph-γ9/δ2(OT3)-Fc and the baculovirus DNA were co-transfected into st9 cells. The expression position of TCRγ9/δ2 (OT3)-Fc was identified by Western blot and the expression efficiency of γ9Fc and δ2 (OT3) Fc was tested by flow cytometry (FCM). Furthermore, the binding activity of TCRγ9/δ2 (OT3)-Fc protein with SKOV3 ceils and MNS protein was evaluated with laser scanning confocal microslopy and surface plasmon resonance (SPR). Results The recombinant vector pBACp10ph-γ9/δ2(OT3)-Fc was constructed and TCRγ9/δ2(OT3)-Fc protein was expressed in sf9 ceils. However, the expression efficiency of γ9Fc and 82 (0T3) Fc was quite differ-ent. It was proved that purified TCRγ9/δ2 (OT3)-Fc protein can bind with SKOV3 cell and MNS protein. Conclu-sion TCRγ9/δ2-Fc protein is successfully expressed in baculovirus vector expression system and TCRγ9/δ2-Fc protein can simulate the binding activity of TCR in vitro.

ObjectiveTo study the technique and therapeutic effect of percutaneous cannulate screw fixation to treat the traumatic diastasis of the pubic symphysis.MethodsFrom February 2003 to December 2010,46 patients (27 men and 19 women,mean age of 34.6 years) with unstable pelvic fractures and diastasis of the pubic symphysis were admitted.All the patients were treated by closed reduction and percutaneous cannulate screw fixation of the symphysis pubis.Then to complete the fixation of posterior ring,by percutaneous screw inserted through the sacroiliac joint or posterior iliac wing.According to Tile's classification,the patients were classified into type B1.1 in 4 cases,B1.2 in 7,B2 in 2,B3 in 2,C1.1 in 7,C1.2 in 7,C1.3 in 10,C2 in 5 and C3 in 2.All patients were performed posterior ring fixation except 4 cases of type B1.1.Anteroposterior,inlet and outlet X-ray radiographs and CT scans of the pelvis were taken preoperatively to evaluate the stability and deformities,and after surgery the plain radiographs and CT scans were taken to evaluate the reduction and the location of screws.ResultsThe average operative time was 45 min (range,15-65 min),and the average intraoperative blood loss was 25 ml (range,15-50 ml).Each patient was inserted one screw in the symphysis pubis.Thirty-five patients underwent postoperative pelvic CT scan and 3screws of them penetrated the wall of symphysis pubis.The average follow-up period was 23.5 months (range,5-48 months).In the follow-up period,no infection and displacement were found.The last follow-up result:according to Matta and Tornetta's standard,the result was excellent in 43 cases and good in 3.Among all patients,31 cases (67.39％) had returned to their original works,6 were to give up their original works as complicating injuries; 28 cases had no pain,13 cases had slight pain of the symphysis pubis while to make an effort,5 cases had pain of sacroiliac joint.There were no iatrogenic injury of nerve.ConclusionClosed reduction and percutaneous cannulate screw fixation of the traumatic diastasis of the pubic symphysis is a safe,feasible and easy manipulated method.The operative injuries is small and the clinical outcome is satisfactory.
