Objective To investigate the feasibility and clinical effect of hip joint arthrodesis with the application of Kirschner wire and reconstruction plate in the treatment of advanced tuberculosis in total hip joint.Methods A total of 30 patients with advanced tuberculosis of the hip in our hospital from March 2014 to April 2016 were divided as Kirschner wire group and reconstruction plate according to different surgical methods,with 15 cases in each group.The operation time,bleeding volume during operation (intraoperative and postoperative),fusion time,postoperative complications of two groups were observed and compared.Results Patients of two groups reached bony fusion.Compared with reconstruction plate group,Kirschner wire group had less blood loss,shorter operative time,longer fusion time,the differences were statistically significant (P < 0.05).Conclusion Both Kirschner wire fixation and reconstruction plate arthrodesis are effective for patients with advanced tuberculosis of total hip joint,but the clinical efficacy of Kirschner wire fixation in hip arthrodesis was significantly better than the reconstruction plate.

Objective To investigate the effects of melatonin on oxidative stress and neuronal apoptosis in hippocampus of epileptic rats and the mechanism. Methods Seventy-two adult male Sprague-Dawley rats were equally divided into control group, model group, low dose group and high dose group. The model group was injected coriamyrtin 50μg/kg in the lateral ventricle, while the low dose group and high dose group were injected melatonin 20 mg/kg and 60 mg/kg, respectively, 30 minutes before injection of coriamyrtin. The contents of malo-ndialdehyde (MDA) and superoxide dismutase (SOD) were detected with ultraviolet spectrophotometer, the apoptosis was detected with TU-NEL, and the ultrastructural changes of neurons and mitochondria in hippocampal CA3 region were observed with electron microscopy, af-ter 60 minutes of epilepsy. Results The neurons and mitochondria in hippocampus were damaged, the number of apoptotic cells significant-ly increased (P<0.001), the content of SOD decreased (P<0.001), and the content of MDA increased (P<0.001) in the model group, com-pared with the control group. In the low dose group, the ultrastructural damage relieved, the number of apoptotic cells decreased (P<0.01), the content of SOD increased (P<0.05), and the content of MDA decreased (P<0.05);and for the high dose group, the ultrastructural damage relieved very much, the number of apoptotic cells decreased (P<0.001) and was not significantly different from the control group (P>0.05), SOD increased (P<0.001), and MDA decreased (P<0.001), compared with the model group. Conclusion Exogenous melatonin may signifi-cantly reduce neuronal apoptosis in rat hippocampal after epilepsy, and high dose is more effective, which may relate with resistance of oxi-dative stress, alleviate neuronal mitochondrial damage.

Objective:To evaluate the efficacy of Baduanjin combined with mecobalamin tablets in the treatment of type 2 diabetic peripheral neuropathy. Methods:Eighty patients with type 2 diabetic peripheral neuropathy who met the inclusion criteria were randomly divided into two groups with 40 patients in each group ( n=40). The control group took oral mecobalamin tablets and self-management, and the treatment group were treated with Baduanjin on the basis of the control group. All patients were treated for 12 weeks. The clinical symptoms were evaluated by Toronto Clinical Scoring System (TCSS), and the motor nerve conduction velocity (MCV) of tibial nerve and the sensory conduction velocity (SCV) of superficial peroneal nerve were measured by EMG evoked potential instrument. The hemorheological indexes (whole blood low shear viscosity, whole blood high shear viscosity and plasma viscosity) were measured before and after treatment. The clinical efficacy was evaluated and adverse events were recorded. Results:In the course of treatment, 39 patients in each group completed the study with each one dropout. The total effective rate was 87.2% (34/39) in the treatment group and 64.1% (25/39) in the control group. There was significant difference between the two groups ( χ2=5.64, P=0.018). After treatment, the TCSS score of the treatment group was significantly lower than that of the control group ( t=-6.23, P<0.01), the tibial nerve MCV (43.06 ± 4.19 m/s vs. 39.55 ± 4.30 m/s, t=3.65), the superficial peroneal nerve SCV (43.23 ± 4.31 m/s vs. 39.92 ± 3.74 m/s, t=3.62) in the treatment group were significantly higher than the control group ( P<0.001), while the whole blood high shear viscosity, the whole blood low shear viscosity, and the plasma viscosity in the treatment group were significantly lower than the control group ( t value were -10.36, -14.21, -13.88, all Ps<0.001). During the treatment, no serious adverse events occurred in both groups. Conclusion:Baduanjin combined with mecobalamin tablets in the treatment of type 2 diabetic peripheral neuropathy can reduce blood viscosity, promote blood circulation, increase nerve conduction velocity, improve clinical symptoms and signs, and improve clinical efficacy.

Dementia with Lewy bodies(DLB)is the second most common neurodegenerative dementia after Alzheimer's Disease(AD). This article will mainly elaborate the relationship between DLB and blood-brain barrier(BBB)from the following five aspects: (1)The structure and function of BBB; (2)In vivo assessment methods for the blood-brain barrier damage; (3)Evidence for the damage of blood-brain barrier in DLB; (4)The relationship between α-synuclein and the blood-brain barrier; (5)The relationship between APOE and the blood-brain barrier.Future research should focus on the pathogenesis of BBB damage in DLB patients, by which new drug targets for disease diagnosis and treatment may be found.

Neurofibrillary tangle-predominant dementia(NFTPD)is one type of late-onset dementia, with memory disorders as the main clinical manifestation.The pathological feature is the presence of a large number of neurofibrillary tangle(NFT)in the hippocampus with no or little amyloid deposition in the brain.In recent years, primary age-related tauopathy(PART)has been proposed as a new pathological term, which means that NFT appears in the medial temporal lobe with aging, but no amyloid deposits, and NFTPD is one type of dementia associated with the progression of PART.
