Objective To investigate the effects of standard large trauma craniotomy on neuron-specific enolase(NSE)inflammatory factors in patients withintracranial hematoma caused by severe trau-matic brain injury(sTBI).Methods A total of 64 cases of sTBI patients were randomly divided into con-ventional surgery group (conventional group)and standard large trauma craniotomy group (standard group),with 32 cases in each group.The postoperative Glasgow Outcome Scale(GOS)score,preoperative and postoperativeserum inflammatory factors(IL-8,IL-6,TNF-α,ICAM-1 ,and IL-1 0),NSE levels,and postoperative complications were compared.Results The GOS score of the standard group was signifi-cantly superior tothe conventional group(P <0.05);postoperativeIL-6,TNF-α,ICAM-1 ,and NSE levels in the conventional group were significantly reduced(P <0.05);postoperativeIL-8,IL-6,TNF-α,ICAM-1 ,and NSE levels were significantly reduced and IL-1 0 levelswassignificantly improvedin the standard group(P <0.05);there were3 cases of postoperative cerebrospinal fluid leakage and four cases of inci-sional hernia in the conventional group,and two cases of postoperative cerebrospinal fluid leakage and three cases of incisional hernia in the standard group;there were no significant differencesin the incidence of postoperative complications in both groups(P >0.05 ).Conclusion Inflammatory factors and NSE both playimportant roles in sTBI.Standard large trauma craniotomycan control these indicators effectively and reduce the severity of the patient's illness.

Objective To observe the clinical efficacy of cervus and cucumis polypeptide combined with Duhuo Jisheng Decoction Jiaji pain point injection in the treatment of lumbar intervertebral disc herniation. Methods Totally 68 cases of patients with lumbar intervertebral disc herniation were randomly divided into treatment group (34 cases) and control group (34 cases). Both groups were given Duhuo Jisheng Decoction orally besides basic treatment, and the treatment group received cervus and cucumis polypeptide Jiaji pain point injection additionally. Both groups were in a course of 10 days and treated for two courses. The clinical symptoms, visual analog pain scale (VAS), and Oswestry disability index (ODI) of the two groups were observed and compared among those before treatment, after one and two courses of treatment. Results Compared with the pretreatment of the same group, the VAS and ODI scores were lower after the first and second courses of treatment (P<0.05). After one and two course of treatment, VAS and ODI of the treatment group were lower than the control group (P<0.05, P<0.01). After one course of treatment, the total efficiency of treatment group was 91.2%(31/34), while the control group was 70.6%(24/34);after two courses, the total efficiency were respectively 100%(34/34) and 85.3%(29/34);the treatment group was better than control group during the same period (P<0.05). Conclusion Cervus and cucumis polypeptide combined with Duhuo Jisheng Decoction Jiaji pain point injection has good clinical efficacy in the treatment of lumbar intervertebral disc herniation.

Objective To investigate cytotoxicity,biocompatibility and new bone formation traced of Chinese porous tantalum,and provide experimental strategies for further clinical application.Methods The physical properties of the porous tantalum were observed by the SEM.The osteoblasts were isolated from rabbit embryo.The extract fluid from tantalum was made.The cytotoxicity and proliferation of osteoblasts compounded with porous tantalum in vitro were detected by the MTT assay.The osteoblasts were co-cultured with extract of tantalum in vitro and the morphological changes,proliferation and adhesion were observed under SEM.A total of 24 New Zealand rabbits were used to establish the model of femoral condyles with porous tantalum bars implanted.Among which 4 of them was injected with calcein and alizarin on the 5th day and the 19th day and sacrificed at 10 week postoperatively.The specimens were observed with LSCM at 488 nm and 543 nm wavelength respectively.The remained 20 animals were sacrificed successively at 2,4,8,12 weeks of implantation,then were examined by histological observation.Results The SEM showed that the pore of porous tantalum were three-dimensional connected morphology.MTT assay showed that the osteoblasts grew well in extract and no significant difference between experimental and control groups.The osteoblasts grew and spread extensively on porous tantalum.Early on co-culture,the osteoblasts attached to the surface and inner walls of material,in the later stage,the osteoblasts excreted bone matrix over the surface of porous tantalum.The animal model showed that porous tantalum was bonded closely with host bone.Hard slicing showed that new bone and capillary regenerated on tantalum-bone interface at 2,4 weeks postoperatively.The pores were full with bone tissue at 8,12 weeks.The LSCM indicated that the green and red fluorescence-labeled new bone was displayed on tantalum-bone interface,while the red zone located around the green zones.They appeared to be discontinuous at early stage,but connected with each other at the end.Conclusion The Chinese porous tantalum has good biocompatibility and no cytotoxicity.The contact osteogenesis and bone conduction exist in tantalum-bone interface,and in a time-dependent manner.

Objective To observe the hypoglycemic mechanism of total saponins of Momordica charantia (MC) in type 2 diabetes mellitus (DM) rats. Methods Among the selected 60 male Specific Pathogen Free (SPF)rats, 8 were random- ly chosen as control group, while others were fed with high fat and high glucose diet following streptozotocin injection from caudal vein 8 weeks after to construct type 2 DM models. After the DM models were successfully built, rats were then ran- domized into five groups: DM control group (n=8), the metformin group (n=8) and three groups of total saponins of MC with different dosage (n=8 in each group). The total saponins of MC groups include DM rats administrated with total saponins of MC 100, 200, 400 mg/(kg·d) for 8 weeks, the metformin group include DM rats administrated with metformin 50 mg/(kg·d) for 8 weeks. At the end of the experiment, the fasting blood glucose and insulin were examed. At the same time, a part of pan- creas islet, liver and skeletal muscle were preserved. The pancreas islet structure, the hepatic glycogen and Glucose trans- porter 4 (GLUT4) expression were observed by electron microscope, glycogen dyeing and immunoblot respectively. Results After 8 weeks treatment, compared to type 2 DM control group, fasting blood glucose and insulin values in MC groups were reduced more obviously. However, skeletal muscle GLUT4 expression level, insulin granules and hepatic glycogen increased obviously in MC groups. Conclusion Total saponins of MC has hypoglycemic effect. It’s mechanisms maybe include pro- moting the hepatic glycogen synthesis, inhibiting the hepatic glycogen decomposition and promoting insulin sensitivity by in- creasing peripheral tissue’s GLUT4 expression.

There are many methods for internal and external fixation of limbs fractures,such as plaster,splint,and traction.But the disadvantages such as destroyed local blood supply,unreliable fixation,inappropriate dynamic and static combination,postoperative nursing,delayed functional recovery and complications limit their application.Multifunctional external fixation apparatus has been used to treat limbs fractures.It avoids to dissect surrounding tissues and does not damage blood supply out of medullary cavity,which benefits wound treatment,early functional exercise,prevents joint adherence,improves cure rate,reduces complications and avoids second surgery.Moreover,this method is an effective fixation,saves treatment time and prevents adverse results due to treatment for other wounds.In addition.it can also be used to treat bone nonunion,infective fracture,bone defect and other fracture complications.
