OBJECTIVETo study clinical effects of unilateral pedicle screw-rod system fixation combined with the single the cage of interbody fusion in the treatment of lumbar degenerative instability via paraspinal intermuscular approach under MAST Quadrant retractor.

METHODSFrom February 2010 to December 2011, 39 patients with lumbar degenerative instability after invalid conservative treatment were treated with unilateral fixation combined with interbody fusion via the paraspinal intermuscular approach under MAST Quadrant retractor. The indexes such as the operative time, blood loss, complications, VAS pain scores, JOA (subjective symptoms of low back pain,lower limb pain and numbness, sensory disturbance, movement disorders) scores, modified Macnab criteria for curative effect evaluation were observed before treatment, at the 1st month after treatment and the latest follow-up. The intervertebral fusion was studied on the X-ray at the latest follow-up.

RESULTSAll the patients were followed up, and the mean during was (22.3 +/- 8.6) months. The operation time was (138 +/- 46) min, and the amount of bleeding was (335 +/- 152) ml. There were no complications such as cerebrospinal fluid leakage and spinal nerve injury during operation, and no incision infection after operation. The VAS pain score was reduced from preoperative 7.93 +/- 1.27 to 2.05 +/- 1.18 on the 1st month after operation and 1.89 +/- 0.42 at the latest follow-up. The JOA total score was improved from preoperative 1.59 +/- 0.42 to 8.86 +/- 0.37 on the 1st month and 9.02 +/- 0.29 at the latest follow-up. According to modified Macnab criteria, there were 17 cases got an excellent result, 19 good, 3 case fair. Thirty-five patients got intervertebral bony fusion at the latest follow-up.

CONCLUSIONUnilateral pedicle screw-rod system fixation combined with single cage interbody fusion in the treatment of lumbar degenerative instability via paraspinal intermuscular approach under MAST Quadrant retractor is a safe, minimally invasive, satisfactorily effective methods to treat lumbar degenerative instability.

OBJECTIVETo introduce the method and evaluate the efficacy of endoscopic repair of nasal septal perforation with acellular dermal matrix and pedicled mucoperichondrial flap.

METHODSTwelve patients with perforation of nasal septum were encountered since February 2006 to October 2010. The most common symptoms and sings were nasal obstruction and crusting at the margin of the perforation. Eight of 12 patients were iatrogenic following surgery. The perforation typically located at anterior medial part of the nasal septum, with their sizes ranged approximately 1.0-2.3 cm in diameter. The incision was made at the anterior edge of the perforation from the left nasal cavity and continued to the nasal floor horizontally. It ended at the lateral nasal cavity. Then, another incision was made parallel to the first one, which was 1.5 cm from the posterior of the perforation. The two incisions was connected. The mucoperichondrium was stripped along with the incisions and the pedicle of mucoperichondrial flap kept on the nasal septum. Then, the flap was turned up to cover the perforation and fixed with apposition suture. Put the acellular dermal matrix graft on the perforation from the right nasal cavity and fixed it with apposition suture.

RESULTSThe healing of the acellular dermal matrix and mucoperichondrium was good in the first week postoperatively and there was no rejective reaction and contracture. The epithelization of the nasal septal perforation finished 4 weeks after surgery. Follow-up ranged from 3 months to 4 years. Eleven patients had successful outcomes with complete closure of their perforations. One patient failed the operation. All of them had no complications.

CONCLUSIONSUsing acellular dermal matrix graft and mucoperichondrial flap to repair the septal perforation is a simple method and the success rate is high. Therefore, it is an effective way to repair the perforation of nasal septum.

The influence of 3α-androstanediol (3α-diol) on twitch and electroencephalogram (EEG) of the epileptic rats induced by pentylenetetrazole (PTZ) has been observed in this experiment in order to comprehensively explore the role of 3α-diol on epileptic attack from the aspects of behavior and EEG. Thirty-two male Sprague-Dawley rats were evenly and randomly divided into 4 groups: the normal and supplied with oil epileptic (N+oil+PTZ) group, the normal and supplied with 3α-diol epileptic (N+3α-diol+PTZ) group, the gonadectomized and supplied with oil epileptic (GDX+oil+PTZ) group and the gonadectomized and supplied with 3α-diol epileptic (GDX+3α-diol+PTZ) group. The changes of the behavior and EEG of epileptic rats in every group were recorded and analyzed. The results of behavior observation showed that the latency to clonic seizure and tonic-clonic seizure was shortened and the number of tonic-clonic seizure was increased significantly in the GDX+oil+PTZ group in comparison with N+oil+PTZ group (P < 0.05); comparing GDX+3α-diol+PTZ group with GDX+oil+PTZ group, or N+3α-diol+PTZ group with N+oil+PTZ group, we found that the latency to clonic seizure and tonic-clonic seizure became prolonged significantly, and the number of clonic seizure and tonic-clonic seizure was decreased significantly (P < 0.05). The results of EEG showed that the latency to epileptic waves was cut and the number of epileptic waves was augmented significantly in the GDX+oil+PTZ group in comparison with N+oil+PTZ group (P < 0.05); comparing GDX+3α-diol+PTZ group with GDX+oil+PTZ group, or N+3α-diol+PTZ group with N+oil+PTZ group, we found that the latency to epileptic waves became lengthened significantly, the number of epileptic waves was reduced significantly and the percentage of change of TP (total power of spectrum) was lessened significantly (P < 0.05). These results indicate that 3α-diol has an antiepileptic activity in the gonadectomized and normal epileptic rats.

OBJECTIVETo explore the common causative genes and mutation sites for hereditary non-syndromic deafness in Shanxi.

METHODSPeripheral blood samples were collected from regional schools for children with deafness. The samples were analyzed by matrix-assisted laser desorption ionization of flight mass spectrometry, and the results were verified by DNA sequencing.

RESULTSFor all samples, the 20 mutational sites of the 4 common causative genes were tested. As revealed, c.235delC of GJB2 gene has the highest mutational rate (13.67%). c.IVS7-2A>G of SLC26A (PDS) gene has a mutation rate of 17.67%, and c.1555A>G of mitochondrial 12S rRNA has a mutation rate of 2.00%. No mutations have been found with GJB3 gene. Sequencing analysis has suggested that the above results have a consistency rate of 99%.

CONCLUSIONAnalysis of mutations of the 4 common deafness-related genes can facilitate early diagnosis and treatment for the disease. Matrix-assisted laser desorption ionization time of flight mass spectrometry is a reliable method for such a task.

OBJECTIVETo explore the effect of 18-β glycyrrhetinic acid (GA) on the endoplasmic reticulum of nasal epithelial cells in allergic rhinitis (AR) model rats.

METHODSTotally 96 Wistar rats were randomly divided into the blank group, the AR model group, the loratadine group, the GA group, 24 in each group. AR models were established by peritoneally injecting ovalbumin (OVA). Morphological scoring was performed. GA at 21. 6 mg/kg was intragastrically administered to rats in the GA group. Nasal mucosal tissues were taken for electron microscopic examinations at the second, fourth, sixth, and tenth week after drug intervention.

RESULTSThe overlapping score was 2.10 ± 0.45 in the blank group, 5.10 ± 0.56 in the loratadine group, 5.10 ± 0.56 in the AR model group, 5.20 ± 0.78 in the GA group, showing statistical difference when compared with the blank group (P < 0.01). Results under transmission electron microscope showed that the number of the endoplasmic reticulum increased in the AR model group, with obvious cystic dilatation, a lot of vacuole formation, and degranulation. A large number of free ribosomes could be seen in cytoplasm. With persistent allergen exposure, changes mentioned above was progressively aggravated in the endoplasmic reticulum of nasal mucosal epithelium in the AR model group. But the dilation of endoplasmic reticulum, vacuole formation, and degranulation were relieved in the GA group, and got close to those of the blank group.

CONCLUSION18-β GA could improve the expansion, vacuolization, and degranulation of the endoplasmic reticulum of nasal epithelial cells in AR model rats.

OBJECTIVETo summarize our clinical experience in adult-to-adult living donor liver transplantation (ALDLT).

METHODSClinical data of 12 patients with ALDLT performed in our center from September 2000 to June 2005 were analyzed, retrospectively.

RESULTSLeft lobe (segments II, III, IV, including the middle hepatic veins) transplantation was performed in 3 patients and right lobe (segments V, VI, VII, VIII, with or without the middle hepatic veins) transplantation was performed in 9 patients. Donors: There were no operative deaths. The median operative time was 6.20+/-1.40 hours and their blood loss ranged from 300 ml to 1200 ml. Postoperative complications included biliary fistula (1 donor) and wound fat liquefaction (1 donor). During a 6-12 months follow-up, no long-term complications were found. Recipients: The operating time ranged from 5 to 11 hours and their blood loss ranged from 800 to 7000 ml. Modified outflow reconstruction, microvascular reconstruction of the hepatic artery and duct-to-duct biliary reconstruction were done during the recipient operations. The median cold ischemia time was 1.90+/-0.50 hours. The median anhepatic phase of recipients was 1.63+/-0.43 hours. Graft/recipient weight ratio (GRWR) was (1.20+/-0.26)%. One recipient presented a postoperative complication of biliary fistula and another recipient died 1 month after the operation from serious infection. The other 11 recipients had long-term survivals.

CONCLUSIONALDLT is an effective treatment for decompensated end-stage liver disease patients and is relatively safe for the donors.
