Objective:To investigate the therapeutic effects of bridge internal fixation system on the treatment of periprosthetic femoral fracture of Vancouver type B1.Methods:From June 2013 to October 2018, 10 patients with periprosthetic femoral fracture of Vancouver type B1 were treated by bridge internal fixation system at Department of Orthopedics, Zhucheng People's Hospital Affiliated to Weifang Medical College. They were 3 males and 7 females, aged from 65 to 84 years (average, 73.6 years). All patients had received hip replacement due to femoral neck fracture, including 6 hemi-hip replacements and 4 total hip replacements. Fracture had occurred in 9 cases after the primary hip replacement and in one case after revision. The time from primary hip replacement to the present surgery ranged from 1.5 to 4.0 years (average, 2.5 years). Recorded were operation time, intraoperative blood loss, fracture healing time, hip joint function and complications at the last follow-up.Results:In this group, operation time ranged from 65 to 114 min (average, 82 min), intraoperative blood loss from 110 to 320 mL (average, 145 mL). The 10 patients were followed up for 12 to 18 months (average, 15 months). Their X-ray films showed that bony union was achieved in all after 3 to 6 months (average, 4.3 months). According to their hip Harris scores at the last follow-up, 7 cases were rated as excellent, 2 as good and one as fair. Follow-ups revealed no loosening or breakage of implants, infection, femoral prosthesis loosening, fracture or femoral prosthesis displacement.Conclusion:Bridge internal fixation system is a good way to treat periprosthetic femoral fracture of Vancouver type B1, leading to satisfactory short-term outcomes and fine functional recovery.

Objective To explore the efficacy of autologous pleural patch in surgical operation on the patient with chronic tuberculous empyema.Methods Autologous pleura patches were used to repair the pulmonary wound in the surgical operations for 7 patients with chronic tuberculous empyema,who received surgical management in Hebei Provincial Chest Hospital from August 2012 to November 2014.The leak time of the patient and the time of the chest tube were recorded,the pulmonary re-examination was observed by chest X-ray,and the follow-up results were recorded.Results The time of persistent pulmonary air leak of 6 patients was not more than 10 hours after operation,1 patient was not more than 24 hours.Review of X-ray chest showed that good for lung,4-7 d after operation removal of thoracic dosed drainage tube,there was no death and no chest infection in 7 patients and review of CT chest showed no significant residual cavity.After follow-up for 6-24 months 7 patients had satisfactory efficacy,there was no pneumothorax and thoracic infection,no residual cavily.Conclusion Autologous pleura can be used to patch the pulmonary wound in the surgical operation on the patient with chronic tuberculous empyema.

<p><b>OBJECTIVE</b>To study the anticonvulsive action of scorpion alcoholic extraction (SAE) on phenytoin-resistant convulsive rats made by direct cortical electrical stimulation in order to investigate the mechanism of antagonizing drug-resistance of SAE.</p><p><b>METHOD</b>Using the method of implanting microelectrodes in the cortical motor area of the brains of rats where the brain tissue was stimulated frequently by electricity through microelectrodes until igniting and then PHT (0.154 g x kg(-1) x d(-1)) ig for 7 days, We established phenytoin-resistant convulsive rat model. Total 6 groups were set up in the experiment: Normal control group, convulsion model control group (CMCG), phenytoin-resistant convulsion control group (PRCG), verapamil positive control group (VPCG, 0.0385 g x kg(-1)), scorpion alcohol extraction (SAE1, 6.5 g x kg(-1)) and scorpion alcohol extraction (SAE2, 13.0 g x kg(-1)). After ig both doses of SAE (6.5, 13.0 g x kg(-1)), the effects of SAE on the changes of convulsion threshold of phenytoin-resistant convulsive rats were observed. The method of RT-polymerase chain reaction (RT-PCR) was used to detect the changes of mdrl gene expression and the method of immunohistochemistry (SABC) was adopted to determine the changes of P-gp expression.</p><p><b>RESULT</b>Both doses of SAE and verapamil (Ver) ig all raised the convulsant threshold of phenytoin-resistant rats (480.38 +/- 18.48) microA, there were statistical differences (P < 0.05) compared to themselves before drugs-treated. PHT was administrated, and mdrl mRNA and P-gp expression in PRCG was much higher than that in CMCG, with significantly statistical difference (P < 0.01); ig both doses of SAE and Ver all decreased mdrl mRNA and P-gp expression compared to PRCG respectively (P < 0.01).</p><p><b>CONCLUSION</b>SAE and Ver ig all produce antagonizing action on phenytoin-resistant convulsive rat model. The machanism is related with inhabiting the mdrl mRNA expression and further decreasing the product P-gp.</p>

AIM To investigate the anticonvulsive action of supercritical CO2 ethanol extract from Pinellia Pedatisecta Schott(SEE-CO2PP). METHODS The rat convulsive model was induced by penicillin localized injected in rat cortex. The effects of SEE-CO2PP on the latency of seizure and changes of convulsive behaviors were investigated. The latency of epileptiform discharge, and frequency and amplitude of highest wave in cortex and hippocampus were recorded by using RM6240C multichannel physiological signal collection and analysis recorder. At the same time, the contents of glutamic acid (Glu), aspartic acid (Asp), glycine (Gly) and γ-aminobutyric acid (GABA) in hippocampus were determined with high performance liquid chromatography. RESULTS SEE-CO2PP 15 and 30 g·kg-1, ig, prolonged the latent period of seizure and weakened the extent. SEE-CO2PP also prolonged the latent period of epileptiform discharge, reduced the frequency and decreased amplitude of the highest wave in both cortex and hippocampus. Moreover, SEE-CO2PP increased the content of GABA in hippocampus, but the levels of Gly,Asp and Glu had no obvious changes. CONCLUSION SEE-CO2PP inhibits the epileptiform discharge and convulsive behaviors of convulsive model rats, which suggests SEE-CO2PP has anticonvulsive action.

Aim To investigate the effects of topiramate (TPM) o n the model of seizure rats induced by penicillin and explore its mechanism of ant iconvulsant action.Methods Using the model of seizure rats indu ced by penicillin localized injected in cortex, we investigated the effect of TP M on the changes of seizure extent and recorded the latency of epileptiform disc harge, frequency of epileptiform wave, highest wave of hippocampus EEG. The leve ls of Glu, Asp, Gly and GABA in hippocampus were determined by high performance liquid chromatography (HPLC). Results Compared with the model g roup, TPM (110 mg?kg -1, 440 mg?kg -1, ig) could significantly light ened the extent of seizure, prolonged the latency of epileptiform discharge, red uced the frequency of epileptiform wave and minished the highest wave of hippoca mpus EEG (P
