Chinese Journal of Applied Clinical Pediatrics 2015;30(23):1838-1840
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.

With the implementation of the strategies for the development of our country through science and education and talents, and of the"211 and 985 projects", there has been a more substantial increase in the scientific and technological strength and international competitiveness of research universities, reflected in the year-by-year increase in the number and total funding of research projects taken up by universities, and in the output results. All the achievements rely on the increasing investment of the government in the fields of science and technology and on hard-working scholars and students who devote themselves to scientific research, as well as the prospective planning and scientific decision making of leaders, and the concerted efforts, standard management and guiding service of the administrative departments. In the present paper the important role of the president's office of a university in ensuring that research work can be running smoothly is explored through analysis on the assistant role of the president's office of Peking University Health Science Center, and its practice in the provision of service-oriented management and promotion of the innovation and development of scientific research by close cooperation with the research management department and integrated coordination of all the individual administrative departments.

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 investigate the methods of X-ray diagnosis of various displacement of unstable pelvic fracture in three-dimensional space and its instructive significance in closed reduction.Methods A normal adult pelvic specimen was selected and fixed in a wood-frame at supine position after soft tissue rejection and ligament preservation.With the breakage at the unilateral anterior-posterior ring,models of hemipelvic rotation in the transverse and sagittal planes and hemipelvic vertically upward displacement were induced.Anteroposterior radiographs of the pelvic specimen were made and picture archiving and communication system (PACS) was used to measure width of iliac wing,suprainferior diameter of hemipelvis,vertical displacement of iliac crest,acetabulum roof,pubic tubercle and sciatic tuber and area of obturator foramen.Methods of X-ray diagnosis of various displacements of hemipelvis were concluded and applied in treatment of 43 patients with unstable pelvic fractures.Operation time and intraoperative blood loss were recorded.Postoperative images were evaluated by Matta standard.Results Hemipelvic rotation in transverse plane included eversion and inversion.Width of iliac crest was enlarged and area of obturator foramen was shrunk while extroversion ; on the contrary,an opposite result was observed while inversion.Sagittal rotation included pronation and supination.Pubic tubercle had obvious downward shift,iliac crest presented no change or slight upward shift,suprainferior diameter of hemipelvis was lengthened,iliac roof and sciatic tuber remained their position unchanged and area of obturator foramen was shrunk while pronation; on the contrary,pubic tubercle had obvious upward shift,iliac crest presented no change or slight downward shift,suprainferior diameter of hemipelvis was shortened,iliac roof and sciatic tuber remained their position unchanged and area of obturator foramen was enlarged while supination; iliac crest,acetabular roof,pubic tubercle and sciatic tuber presented equidistant upward shift while the hemipelvis displaced upward vertically.Average operation time was 55 minutes (range,15-85 minutes) and intraoperative blood loss was 26 ml (range,10-50 ml).According to Matta standard,pelvic radiography evaluation at postoperative 3 days was excellent in 31 cases and good in 12 cases,with excellent and good rate of 100%.Conclusion Pelvis X-ray films are able to diagnose various three-dimensional displacement of unstable pelvic fractures and guide closed reduction timely and rapidly to achieve satisfactory result.

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.
