Some practices of work related stress in USA and Chinese special education field were discussed in the article. In the end, the author took a perspective on future research of teacher's work related stress in Chinese special education field.

Objective To analyze the influence of different types of seizures and nonepileptic events on peripheral white blood cell (WBC)counts. Methods We prospectively collected blood samples from all patients and detered WBC count to evaluate the relation of each type of seizure,duration,frequencies,and ttme lapse between a seizure and collection of blood sample to peripheral WBC count. Results Peripheral WBC count was elevated in about 50% cases after a generalized seizure. The length of a seizures was positively associated, whereas its frequencies and the lapse time was negatively correlated with the increase in WBC counts. Conclusion Peripheral WBC counts increase significantly after a generalized seizure.

OBJECTIVETo compare clinical effects between percutaneous compressing plating (PCCP) and proximal femoral nail antirotation (PFNA) for the treatment of patients with intertrochanteric fracture with risk external wall.

METHODSFrom September 2007 to June 2010, 43 patients with intertrochanteric fracture with risk external wall were treated by PCCP or PFNA according to different kinds of internal fixations. There were 22 cases in PCCP, including 9 males and 13 females with an average age of 68.4 (ranged, 60 to 86) years old, and 13 cases with type A2.2 and 9 cases with type A2.3; while 21 cases in PFNA, including 7 males and 14 females with an average age of 67.7 (ranged, 57 to 93) years old, and 10 cases with type A2.2 and 11 cases with type A2.3. Blood loss, operation time, hospital stay, fracture healing time, complications and Harris score after 1 years' following-up were observed and compared.

RESULTSAll patients were followed up for 12 to 22 (means 18.4) months, and all patients were obtained fracture healing, and recovered walking ability as before injury. There were no significant differences in blood loss, operation time, hospital stay, fracture healing time, complications and Harris score after 1 years' following-up (P>0.05). One case occurred displacement on the top of greater trochanter, and 1 case injuried weakness of hip abduction. One case occurred screw breakage in PCCP, while 1 case occurred hip joint pain in PFNA.

CONCLUSIONBoth of PCCP and PFNA in treating patients with intertrochanteric fracture with risk external wall can receive good clinical effects, while the effects and therapy strategy for displacement of bone on the top of lateral wall should further study.

ITS2 sequence was used as a barcode to identify Viticis Fructus and its adulterants. The study collected 46 samples include Viticis Fructus and its adulterants. The sequences were obtained by extracting DNA, amplification, sequencing bi-direstionlly, and then assembling with CodonCode Aligner. To identify Viticis Fructus and its adulterants, the study used the methods of computing the genetic distances by Kimura 2-Parameter (K2P) model and constructing the Neighbor-joining (NJ) phylogenetic trees using MEGA5.0. The results showed that the maximum inter-specific K2P distance of Viticis Fructus was less than the minimum inter-specific K2P distance of Viticis Fructus and its adulterants and the NJ tree indicated that the Viticis Fructus and its adulterants could be distinguished clearly. Therefore, using ITS2 barcode can distinguished Viticis Fructus and its adulterants accurately.

Objective To investigate the surgical approach for adult patients with presacral cystic teratoma.Methods In this study,16 female patients,aged at 26-45 years,with presacral cystic teratoma underwent surgical resection between March 2007 and August 2012.Tumor was primary in 9 cases and recurrent in 7 cases,Rectal examination revealed retrorectal tough semi-circular poorly movable massess with intact rectal mucosa.MR examination showed cystic or solid mass in the anterior sacral,clear boundary,rectum and or vagina compressed.Tumors were completely removed in all cases.Results All patients were cured by surgery,13 cases were cured by one stage resection and 1 was cured by two stage resection.Two cases suffered from recurrence and was cured by reoperation.There were no injury to rectum,anal sphincter,cauda equina,presacral vein.Pathological diagnosis was cystic teratoma.Conclusions By sacrococcygeal surgical resection of presacral cystic teratoma was safe and effective ; complete resection of the tumor capsule is the key to successful operation.

Objective To compare the clinical effects of intramedullary nails and locking compression plate in the treatment of femur shaft fracture.Methods The clinical data and follow-up records of 43 patients with femur shaft fracture treated by intramedullary nails and locking compression plate were retrospectively reviewed.Including 31 males and 12 females with an average age of 40.07 years(25 to73).According to AO classification:5 cases were type A,24 cases were type B,14 cases were type C.26 patients in group A treated by intramedullary nails and 17 patients in group B treated by locking compression plate.Operation time,fracture union time,blood loss and complications were compared between the two groups.The Karlstrom and Olerud result were compared and analyzed.Results All patients were followed up at an average of 15 months(range 5-24) after surgery.According to Karlstrom and Olerud score system,the excellent and good rate of group A was 88.4％,higher than the group B 82.3％.But there was no significant difference between the two groups.In group A:the operation time (113.77 ±20.14)min,the blood loss in the operation (386.74 ± 65.16) ml,clinical bone healing (15.52 ± 1.77) weeks.All these outcomes were better than group B (P ＜ 0.01).One case in group A appeared screw loose,but X-ray showed the nail stable,the bone wasn't displacement.One case in group B appeared broken plate 1 month after operation,and received twice operation,the clinical outcome was good as well.Another 1 case with fracture delayed union in group B,after internal fixation removed,we check the X-ray showed bone union.Conclusion Two methods of treatment femur shaft fracture can all reach the above requirement.Fixation of intramedullary interlocking nail is the preferred surgery than locking compression plate.

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.

Appendectomy involves several key concepts in the foundation course of operative surgery. So it is the best choice to test whether the students can be flexible in using and fully under-stand what they learned about the basic theories and skills of appendectomy. Changzheng Hospital applies Wechat-ald team-based learning and problem-based learning teaching in appendectomy-related courses by actively delivering messages with content of educational administration, basic knowledge, clinical images and videos to the micro-groups, achieving instantly efficient information dissemination and interactive communication. It breaks the shackles of traditional classroom in space and time, mo-bilizes students' enthusiasm for learning, enhances their communicational skills and sense of team-work and improves students' comprehensive analysis and practical ability, therefore achieving better teaching results.
