Objective To investigate the effect of baicalin on inflammatory factors and oxygen free radical metabolism in patients with traumatic shock.Methods 38 patients with traumatic shock were treated with baicalin 200mg intravenous injection when admitted to hospital.Before and 1 h after treatment,TNF-α,IL-6,IL-8,MDA and SOD were measured in blood.Results Compared with before treatment,TNF-,IL-6,IL-8,and MDA levels were decreased after treatment (t =7.32,6.12,20.21,16.10,all P ＜ 0.05),while SOD activity was significantly increased (t =1.69,P ＜ 0.01).Conclusion Baicalin could inhibit the production and release of inflammatory factors TNF-α,IL-6,IL-8 in patients with traumatic shock,reduce the damage of oxygen free radicals to the cells.Early treatment with baicalin had protective effect on patients with traumatic shock.

Objective To explore the effects of Zhu Ling decoction and Alisma orientalis on the osteopotin mRNA expression in the experimental rat model of renal stone. Methods The experimental rat model of renal stone was set up using glyoxylic acid. Osteopontin mRNA expression in the renal tissues in the experimental rat model of renal stone was detected by RT-PCR. Results Glyoxylic acid obviously increased osteopontin mRNA expression in the renal tissues. Zhu Ling decoction and Alisma orientalis remarkably decreased the expression of osteopontin mRNA in the renal tissues. Conclusion Zhu Ling decoction and Alisma orientalis could decrease the osteopotin mRNA expression in the renal tissues in the experimental rat model of renal stone. The results were helpful for prevention and treatment of renal stone.

Immunomagnetic separation (IMS) was coupled with fluorescent microspheres lateral flow assay (FM-LFA) for rapid detection of S.choleraesuis in this study.The target bacteria were firstly enriched from sample by immunomagnetic beads (IMBs),then eluted by heat treatment and detected by fluorescent microspheres lateral flow test strip.The IMBs was labeled with 30 μg/mg antibody,and the capture efficiency was greater than 90％ against 102-106 CFU/mL of S.choleraesuis with great specificity.The immunofluorescent microspheres were prepared by coupling 300 μg of 11 D8-D4 monoclonal antibody with 1 mg of fluorescent microspheres at pH 6.Monoclonal antibody 5F11-B11 (2.0 mg/mL) and donkey anti-mouse IgG (1.0 mg/mL) were sprayed on nitrocellulose membrane as test line and control line,respectively.The FM-LFA based on IMS was used to detect S.choleraesuis in PBS and milk.The limits of detection in PBS buffer and milk were 1.5×105 CFU/mL and 7.6×105 CFU/mL respectively,which were 10 and 200 times lower than that of traditional fluorescent microspheres lateral flow assay,respectively.The results showed that the method,which could enrich S.choleraesuis in milk effectively,could avoid matrix interference and improve the detection sensitivity,thus had a good application prospect.

[Objective] To study the effects of Buyang Huanwu Decoction and Radix Astragali on astrocytes in gerbils with cerebral ischemia and reperfusion injury. [Methods] Gerbils model of cerebral ischemia was set up by occlusion of bilateral common carotid arteries. The dynamic expression of glial fibrillary acidic protein (GFAP) were determined by immunohistochemical method in reperfusion for 24 and 48 hours after 15 minutes of cerebral ischemia. [Results] Positive expression of GFAP reached a peak in reperfusion for 24 hours and was decreased by Buyang Huanwu Decoction and Radix Astragali. Positive GFAP expression was attenuated in reperfusion for 48 hours and enhanced by Buyang Huanwu Decoction and Radix Astragali increased the expression. [ Conclusion ] The regulatory effect of Buyang Huanwu Decoction and Radix Astragali on astrocytes may be one of its mechanisms in repairing nervous function after cerebral ischemia.

OBJECTIVETo evaluate biomechanical properties in different methods of internal fixation combined with distal tibiofibular syndesmosis injury, in order to provide a theoretical basis for clinical choice.

METHODSSix lower limbs specimens were collected and divided into 5 groups, including normal group, distal tibiofibular syndesmosis injury (injury group), 3 cortexes group, 4 cortexes group and hook-plate fixation group. Neutral position, plantar flexion position (30°), dorsiflexion (20°) supination external rotation position of foot movement were simulated on universal materials tester. Strength, stiffness and stability of ankle joint in 4 kinds of motion conditions were measured.

RESULTSThere was significant differences in strength and stiffness of ankle joint between injury group and normal group in 4 different kinds of motion conditions (P<0.05). Strength and stiffness of ankle joint in 3 cortexes group, 4 cortexes group and hook-plate fixation group were improved obviously in 4 different kinds of motion conditions, and biomechanical indexes were recovered normally or better than normal group. Stiffness of the three fixation groups were better than normal group,but there was no significant differences among three groups (P > 0.05), while stiffness of hook-plate fixation group was closed to normal group.

CONCLUSIONFor distal tibiofibular syndesmosis injury, 1 screw with 3 cortexes, 4 cortexes and hook-plate had a positive impact on strength, stiffness and stability of distal tibiofibular syndesmosis injury stress,and could restore the normal stabllity of ankle joint after reconstruction. While fixing by screw fixation would limit the rototary motion of ankle joint,ankle mortise could not adapt to changes of talus bone, thus induces screw breakage and traumatic arthritis. Hook-plate fixation is more suitable than 3 cortexes or 4 cortexes fixation for bilmechanical properties,and its' stress is more balance and can reduce postoperative complcations.

Accessory navicular source flatfoot is one of the foot deformity of clinical common disease,its treatment method is more controversial, differences in clinical efficacy of different surgical methods, according to accessory navicular source flatfoot symptoms of surgical treatment,there is no uniform standard, around a pair of accessory navicular excision how to reconstruct the arch produced a series of operation methods, the clinical curative effect of different operative methods produce also different, how to develop the operation strategy, choose operation method, and after acessory navicular excision whether to rebuild posterior tibial tendon, how to rebuild, the problems such as how to rebuild is the research hotspot and difficulty, looking forward to further research.

Objective To summarize the experiences in treatment of intertochanteric fractures with proximal femur nail antirotation (PFNA). Methods A retrospective study was done on 136 patients with intertrochanteric fractures treated with PFNA from March 2006 to September 2008. Postoperative reduction quality, long-term radiographic results and function of hip were evaluated separately. All the patients had closed fractures. The operation involved orthopedic traction bed, C-arm image intensifier,closed reduction or limited open reduction and locking technique. Results All patients were followed up for 10-18 months (average 14.5 months), which showed fracture healing in all patients. According to Harris criterion, the function of the hip joint obtained excellence in 129 patients ( 94.9% ). Conclusion PFNA has advantages of simple procedure, minimal invasion, firm fixation and early functional exercises and is an effective method for treatment of intertrochanteric fractures.

Objective To assess the impact of additional cycles of temozolomide on the survival of glio-blastoma(GBM)patients after 6 months of maintenance temozolomide(TMZ)following concurrent TMZ chemo-therapy and radiation therapy. Methods Data of 51 GBM patients from 2009 to 2015 were retrospectively studied and the therapeutic effect was assessed according to whether receiving long-term treatment with TMZ. Results Sev-enteen of fifty-one GBM patients received 8 or more cycles and prolonged treatment improved progression-free sur-vival(P=0.011)and overall survival(P=0.004). Conclusions Extended use of TMZ is safe to GBM patients , which may improve response OS and PFS compared to conventional regimen. Prospective studies in larger popula-tions are needed to better-define the population to whom it can be proposed and its optimal duration.
