Objective To study the clinical significance of P - selection expression in children with viral encephalitis and the correlation between this expression and the cerebral infarction with critical viral encephalitis. Methods Flow cytometric was employed to detect the expression of P- selection on the surface of platelet membrane in 44 children with viral encephalitis(20 light patients and 24 critical patients) and 20 healthy control children. The area of the cerebral infarction was determined by computed tomographic scan in 20 patients with critical viral encephalitis. The correlation between the two variables was analyzed. Results The expressions of P - selection on the surface of platelet membrane on less than 5 days and on 2 weeks after the onset of viral encephalitis were significantly higher in critical patients than those in normal control children and light patients( P

Objective To explore the effects of transcranial magnetic stimulation (TMS) on motor function in patients with Parkinson's disease (PD) using meta-analysis. Methods Eight comparative studies of the effects of TMS were meta-analyzed. Results The combined studies confirmed a significant difference before and after TMS treatment. Between the experimental and control groups the effect was also highly significant. Conclusion TMS may play an active role in the rehabilitation of motor function for patients with Parkinson's disease.

Objective To explore surgical treatment of ulcerative colitis (UC). Methods Clinical data of 16 patients of UC undergoing surgery were retrospectively analyzed. Results In this series,16 out of 78 UC patients undergoing surgery included failing to control symptom by conservative therapy in 10, bowel obstruction in 3,suspected malignance in 3. Eight cases underwent total proctocolectomy and ileostomy,4 with total proctocolectomy and ileal pouch-anal anastomosis (IPAA),2 with total colectomy and ileorectal anastomosis,2 with partial colectomy. Conclusions The main indications for surgery in UC patients were failure of medical treatment, complicated bowel obstruction and suspected malignance. Total proctocolectomy and ileostomy is a cure for UC, total proctocolectomy and ileal pouch-anal anastomosis benifits defecation control but suffering from high incidence of stomal ulcer.

To further explore the result of bilingual teaching in pediatrics,we randomly chose 200 undergraduates of 4 class and released students'questionnaires about bilingual teaching with teaching content before and after class to assess students'understanding of bilingual teaching and analysed appraisal result.We found no significant difference of student score between students accepting bilingual teaching and not accepting the bilingual teaching,but there was difference for English tests and expression level.So we think that students can fully accept the bilingual teaching of pediatrics under the premise with selecting appropriate teaching methods and means.

Objective To compare the bone microstructure and osteoblast and osteoclast activity in different regions of osteonecrosis of the femoral head.Methods The osteonecrosis femoral heads were collected from 10 patients (Ficat Ⅳ) who had undergone total hip arthroplasty from March 2011 to May 2013.There were 6 males and 4 females.Their average age was 47.7 years old (range,40-57 years).The samples were divided into subchondral bone region,necrotic region,sclerosis region and healthy region according to radiographic results,then the bone microstructure,micro mechanism and osteoblasts/osteoclasts activity were analyzed byMicro-CT,RT-PCR,Nanoindentation,immunohistochemistry and Trap staining.Results According to the micro-CT results,the continuity of trabecular bone in necrotic region was damaged.The number of trabecular was increased and the gap was narrowed in sclerosis region.The shape and number of trabecular bone were normal in the healthy region.The elasticity moduli in different regions were:subchondral bone region 13.808±4.22 GPa,necrotic region 13.999±3.816 GPa,sclerosis region 17.266±3.533 GPa and healthy region 11.927±1.743 GPa.The hardness were subchondral bone region 0.425±0.173 GPa,necrotic region 0.331±0.173 GPa,sclerosis region 0.661±0.208 GPa,and healthy region 0.423±0.088 GPa.The trap staining of subchondral bone in healthy region and necrotic region were positive while other regions were negative.Immunohistochemistry staining showed that compared with necrotic region,the RANK and RANKL staining level increased significantly in subchondral bone and necrotic region,while Runx2 and BMP2 staining level increased significantly in sclerosis region.Conclusion The mechanical properties of trabecular have no significant difference between necrotic region and healthy region in the progress of the osteonecrosis,while the bone structure has obvious changes.An active bone resorption is observed in subchondral bone and necrotic region,while a higher bone formation activity is found in sclerosis region.

ObjectiveTo compare the therapeutic effec between sustained low-efficiency dialysis (SLED) and continuous blood purification (CBP) in critically ill patients.MethodsAccording to the treatment ways,96 critically ill patients were divided into SLED group and CBP group.A comparison was made on the biochemical indicators,in-hospital duration,hemodynamic parameters,acute physiology and chronic health evaluation (APACHE-Ⅱ ),the survival and the mortality rates.ResultsAfter treatment,the levels of serum creatine kinase isozyme MB (CK-MB),creatine kinase (CK),creatinine (Cr),glutamic-oxalacetic transaminase (AST),glutamate-pyruvate transaminase (ALT),APACHE Ⅱ score on the 1st,2nd and 7th day were lower than those prior to the treatment in both groups ( P ＜0.05).There were no statistical differences in in-hospital duration, biochemical indicators, APACHEⅡscore,hemodynamic parameters,the survival rate and the mortality rate between the two groups (P ＞ 0.05 ).ConclusionsSLED has similar hemodynamic stability with CBP,and the two methods have similar treatment effects in critically ill patients.However,SLED can be relatively economical and convenient for critically ill patients in clinical.

Objective To explore the surgical treatment of Crohn's disease(CD).Methods Clinical data of 11 patients with Crohn's disease undergoing surgery were retrospectively analyzed.Results 9 cases were diagnosed before operation,with symptoms including abdomen pain,diarrhea or constipation,weight loss,and segmental lesions.Abdominal mass was the most common cause,accounting for 54.5%(6/11)in surgery,and intestinal obstruction was secondary.accounting for 36.4%(4/11),and perianal abscess,9.1%(1/11).Partial enterectomy and anastomosis was the main procedure.3 cases were suspected malignance and underging radical cure.The pathology results showed there was moderate atypical hyperplasia in 2 of 3.Most of the patients had a good recovery and their nutritional conditions were improved obviously(P＜0.05).Conclusion Abdominal mass and intestinal obstruction are the main causes of surgical management in patients with Crohn's disease.The possibility of cancerization is higher in patients with longer medical history.The length of intestine reseeted would be enough with visitable lesions resected,and the operative effects are as good as those underwent radical cure.

Objective To identify the genetic mechanism of fetuses with short limbs deformity.Methods From Aug.2008 to Aug.2011,ten fetuses with obvious short limbs were found in ultrasound screening performed at 18-24 and (or) 30-32 gestational weeks and underwent artificial induced labor with the patient' consent.Amniotic fluid or cord blood of the fetuses was collected for karyotyping analysis and detection of mutation point of fibroblast growth factor receptor 3 (FGFR3)gene by polymerase chain reaction and gene sequencing.One fetus (case 3) who presented with achondrogenesis underwent sequencing of SLC26A2 and Trip11 gene meanwhile.Results Among the 10 fetuses with short limbs deformity,five cases were found during second trimester and five during third trimester.Nine cases were identified as normal karyotype and one was chimera (46,XY/45,XY,- 18).One fetus carried a rare FGFR3 mutation of c.1108G＞T (G370C) and was diagnosed as thanatophoric dysplasia at 21+3 weeks.Three fetus carried c.1138G＞A (G380R) mutation and were diagnosed as achondroplasia.These four families had low recurrent risk because no gene mutations were found in the parents.Three mothers of these four fetuses were pregnant again and had normal neonates now.No mutations were found in all gene sequencing in case 3.Conclusions Karyotyping analysis and sequencing of FGFR3 gene could find causative gene mutations and provide genetic counselling and prenatal diagnosis for some fetuses with short limbs deformity.In the third trimester,achondroplasia is the most possible diagnosis when short limbs fetus is found by ultrasound.
