Objective:To examine the relation between the alteration of condylar endochondral in response to mandibular protrusion and the action time length by establishing a model of mandibular protrusion on young adult rats. Methods: 75 female Sprague-Dawley rats aged 9 weeks were divided into two experimental groups and one control group. In two experimental groups, bite jumping appliances created forward positioning of the condyle for twelve hours and whole day, respectively. The experimental rats, together with the control rats, were sacrificed on days 3, 7, 14, 21 and 30, respectively. Tissue sections were cut in the sagittal plane through the mandibular condyle and were processed for in situ hybridization and immunostaining of type X collagen. Results: The peak of type X collagen protein expression in 24-hour experimental groups appeared on day 21 which was on the top of all experimental groups, while in 12-hour experimental groups it was found on day 30. The results of in situ hybridization were basically in agreement with the results of immunostaining. Conclusion: Both intermittent and continuous mandibular advancement can provoke endochondral ossification in young adult rat condylar, while 24-hour ones can produce more obvious and quicker effect.

Objective: We examined the cause、level of pathology、onset of symptoms、time taken to treatment and outcome of 14 patients with cauda equina syndrome(CES) to determine how these factors influenced the eventual outcome.Methods:14 patients with CES treated at our hospital between 1991 and 1997 underwent laminectomy followed by bilateral decompression.The mean time of followup was 35 months(range 22～48months).Logistical regression analysis was used to manage the data.Results:Out of 14 patients,11 had satisfactory recovery at 2 years postdecompression;3 patients were left with some residual dysfunction.Conclusion:There was a clear correlation between delayed decompression and the poor overall outcome,as well as the presence of perineal anaesthesia and significant sphicter dysfuncation.

AIM: To investigate the effect of homocysteine(Hcy) on the apoptosis of endothelial cells (EC). METHODS: First-passaged human umbilical vein endothelial cells (hUVEC) were cultured with M199 containing 3 mmol/L Hcy. hUVEC apoptosis was detected as follow: demonstration of nuclear changes by Hoechst 33258 staining, agarose gel electrophoresis of DNA fragments, detection of apoptotic cells by flow cytometry following Annexin V-PI doubled stain, Western blot for P53 and Bax protein detection and colorimetry detecting caspase-3 activity. RESULTS: Compared with control, homocysteine induced characteristic apoptotic changes in hUVEC. The chromosomal DNA of hUVEC appeared “DNA ladder” by agarose gel electrophoresis. Apoptotic cells were increased significantly (P

Objective To explore the effect and mechanism of atorvastatin on pulmonary hyper-tension in chronic pulmonary heart disease.Methods Sixty eight patients with chronic pulmonary heart disease were randomly divided into treatment group (n=35) and observation group ( n=33 ).Thirty healthy people were picked up from people taking physical examination at the same stage as control group.Patients in both treatment and observation groups were given routine treatment and the observation group were given atorvastatin (20 mg/d) supplement.Changes in pulmonary function,ultrasound cardiogram,plasma high-sensitive C-reactive protein (hs-CRP) and interleukin (IL-8) were observed before and after 6 months of treatment.Results The levels of hs-CRP,IL-8 and pulmonary arterial pressure in treatment and observation groups are higher than that in normal group before treatment (t=2.87,2.79,3.01,3.28,3.31,3.15,respectively,and P =0.005,0.007,0.004,0.001,0.001,0.002,respectively).The pulmonary arterial pressure,hs-CRP,IL-8 in observation group after treated for 6 months were significantly lower than those before treatment and in treatment group (t=2.17,2.59,2.63,1.91,1.86,1.74,respectively,and P =0.039,0.008,0.007,0.031,0.037,0.042,respectively).The pulmonary function indexes including FEV1 and FEV1/FVC in observation group were much better than those in treatment group after 6 months treatment (t=1.84,2.13,respectively,and =0.037,0.024,respectively).There were no significant differences on these indicators in treatment group after 6 months treatment when compared with before treatment ( P ＞ 0.05 ).Conclusion Atorvastatin can effectively improve the life quality and pulmonary function,decrease pulmonary arterial pressure of patients with chronic pulmonary heart disease.These effects may be related to the inhibition of inflammation in pulmonary vessels.

Objective To evaluate the clinical features in patients with pre- or post-operation epilepsy, and to explore the relationship of secondary epilepsy and craniocerebral operations. Methods The patients involved in present study were admitted and underwent the craniocerebral operations in the General Hospital of PLA from Jun.1999 to Feb.2008. The clinical data of epilepsy occurred at pre- or post-operation were retrospectively analyzed. All the 186 patients were divided into the pre-operation epilepsy group(Group A, n=90 ) and the post-operation epilepsy group(Group B, n=96). Based on a standardized questionnaire, a database was established with Microsoft Access 2007 including the primary etiological factor, the location of epileptogenic focus, the seizure frequency, the seizure type, and the abnormal electroencephalogram (EEG). Results Intracranial tumor and cerebrovascular malformation were the main primary etiological factors in group A, and intracranial tumor, cerebral trauma, cerebrovascular malformation and acute cerebral apoplexy were the main primary etiological factors in group B. The four main primary etiological factors for seizures were discovered in significant difference between group A and group B(?2=45.857 3,P=0.000 0). Cranial computed tomography(CT) or nuclear magnetic resonance imaging(MRI) detected that the most locations of epileptogenic focus were in frontal lobe(31.8% in group A and 29.5% in group B), temporal lobe(30.7% in group A and 26.3% in group B), and parietal lobe(17.0% in group A and 24.2% in group B). The frequency of seizure was significantly decreased in group A(?2=11.313 3,P=0.010 1), and was increased in group B(?2=77.080 3,P=0.000 0). The quantity of abnormal EEG for focal epilepsy was significantly decreased in group A(?2=9.773 4,P=0.007 5), but the increasing quantity of abnormal EEG was not significant in group B(?2=4.366 0,P=0.112 7). No significant difference in seizure type was proved after the craniocerebral operations in group A(?2=0.214 3,P=0.643 4). Campared with the post-operation epilepsy group, the location of epileptogenic focus did not show significant distinction in the pre-operation epilepsy group(?2=1.772 2,P=0.777 6). Conclusions Craniocerebral operation is an effective therapy for the secondary epilepsy with certain epileptogenic focus, and it is one of the definite causes of secondary epilepsy.

OBJECTIVE:To provide reference for the reform of the postgraduate training mode of pharmaceutical professional degree. METHODS:Domestic literatures about postgraduate training mode of pharmaceutical professional degree from 2010 to 2013 were searched and combined with the current education situation in China to conclude and summarize the existing problems and reform strategy.

Type 1 diabetes mellitus(T1DM)is a chronic, immune-mediated disease characterised by the destruction of insulin-producing cells.The specific pathogenesis of T1DM has not been clarified.It is mainly believed that the occurrence of T1DM is caused by the joint action of genetic and environmental factors.The occurrence, development, treatment and prevention of T1DM are urgent problems to be solved.A number of studies have found that vitamin D is involved in the pathological process of many autoimmune diseases and is related to cell proliferation, differentiation, apoptosis and other mechanisms.Vitamin D may play a key role in the pathological mechanism of T1DM.Here we review the relationship between the incidence, prevention and treatment of T1DM and vitamin D.

Objective To investigate the effect of deproteinised calf serum enteric-coated capsules (DCSECC) on cognitive function of patients with epilepsy.Methods Sixty-six patients were randomly divided into two groups including experimental group who received DCSECC 5 mg/d,3 times a day and antiepileptics,and control group who received antiepileptics.To detect the cognitive function by means of Wechlors memory scale (WMS),Montreal cognitive assessment (MoCA),event related potentials (P300) latency period and malondialdehyde (MDA) before treatment and after treatment for 1,2,3 months,and compared with 33 healthy subjects controls (healthy group).Results Compared with healthy group,the scores of memory quotient (MQ) and MoCA were signifiantly decreased in experimental group and control group [(80.4 ± 14.2),(79.6 ± 13.9) scores vs.(103.2 ± 30.1) scores; (13.5 ± 4.5),(12.9 ± 3.9) scores vs.(28.8 ±8.7) scores],in the mean time,P300 latency period and MDA were signifiantly prolonged [(380.8 ± 49.7),(389.5 ± 50.4) ms vs.(309.8 ± 44.7) ms ; (5.0 ± 1.8),(4.8 ± 1.7) μ mol/L vs.(2.2 ± 0.6) μ mol/L],there was significant difference (P ＜ 0.05).Compared with the control group after treatment for 3 months,the scores of MQ and MoCA in experimental group [(96.5 ± 18.3) scores,(26.8 ± 7.7) scores] were increased and P300 latency period [(321.3 ±36.1) ms] was shortened,there were significant differences (P ＜ 0.05).The level of MDA decreased significantly in experimental group after 2,3 months treatment[(3.02 ± 1.04),(2.99 ± 1.01) μ mol/L],there was significant difference(P＜ 0.05).The scores of MQ and MoCA in control group after treatment had no significant difference compared with before treatment (P ＜ 0.05).Conclusions The cognitive function in patients with epilepsy is decreased.DCSECC medical treatment can improve the cognitive function by means of antioxidant activity.
