Objective The current study was aimed to establish an electrically amygdala kindling model of refractory epilepsy in Sprague-Dawley rats, and to study their changes of electrocorticagram ( ECoG ) .Materials and methods Male Sprague-Dawley rats were used in the experiment.Two-polar electrode was implanted into the right amygdala stereotactically.Two weeks after the surgery, electrical stimulations were given to elicit the grade 4 seizure in all animals with the fast kindling protocol.Rekindling was administrated after the first kindling.The after discharge threshold ( ADT) and the number of stimulus were reassessed in the two kindling protocols.ECoG and the behavior of the animals were recorded during the whole experiment.Result The changes of ECoG and behavior: Animals showed stage 1 -3 seizure when the ADT was assessed.While during the kindling period, the animals showed generalized convulsion with stage 4-5 seizure.ECoG showed sharp waves, spike waves, sharp-slow waves and spike-slow waves.Statistical analysis showed that the ADT was not significantly increased at two weeks after kindling ( from 83.33 ±22.29μA to 84.17 ±16.76μA, P=0.923 ) .The number of stimulus given to elicit the stage 4 convulsion was not significantly increased as well ( from 4.41 ±2.27 to 5.58 ±3.96, P=0.231 ) .Conclusions Rapid kindling model of epilepsy in rats is an effective epilepsy model, which is stable for 2 weeks.

Objective To introduce a new kind of circuit with temperature and voltage double compensation function in view of the deficiency of ambient temperature change on existing respiratory signal detection circuit. Methods The respiratory signal is detected by the characteristics of diode junction voltage with temperature changes. Results The functions of automatic temperatures compensation and automatic voltage fluctuation compensation are realized with the differential connection of two identical diodes. Conclusion The experimental results shows that the proposed circuit is basically immune to the fluctuation of ambient temperature changes and voltage fluctuation, its structure is simple and the accuracy of breathing signal detection is also improved.

Objective To investigate the correlation between benign prostate hyperplasia(BPH) and atherosclerotie related indicators.Methods Totally 125 patients were divided into two groups based on prostate volume(PV):50 cases without BPH (PV≤30 ml) and 75 cases with BPH (PV＞30 ml).Age,body mass index (BMI),triglycerides (TG),total cholesterol,low-density lipoprotein cholesterol,high-density lipoprotein cholesterol,glycosylated hemoglobin,prostate specific antigen (PSA),HOMA-IR,bilateral ankle brachial index (ABI) and cardio-ankle vascular index (CAVI) were measured and calculated.All these indicators were compared between two groups.The correlations of these indicators with PV were analyzed.Results BMI,TG,PSA,HOMA-IR and right-CAVI in BPH group were higher than in group without BPH (t=2.177,2.033,3.060,2.859,3.085,all P＜0.05),and right ABI was lower in the BPH group than in group without BPH (t=2.557,P＜0.05).The incidences of diabetes and coronary diseases in BPH group were increased compared with those without BPH (52％ and 36％ vs.30％ and 10％,x2 =5.917,10.648,P =0.015,0.001,respectively).PV was positively correlated with BMI,TG,PSA,right CAVI,left CAVI(r=0.336,0.216,0.556,0.295,0.389,all P＜0.05)by Pearson analysis.Conclusions BPH is closely correlated with insulin resistance and atherosclerosis.Atherosclerosis might cause prostate chronic ischemia and hypoxia,which may play a role in the pathogenesis of BPH.

Studies have shown that microRNA plays a role of oncogene or tumor suppressor gene in the carcinogenesis and progression of tumor.However, the role of microRNA-143 (miR-143) in esophageal squamous cell carcinoma (ESCC) needs further study.Aims: To investigate the expression and clinical significance of miR-143 in ESCC.Methods: Sixty-three ESCC tissues and corresponding para-cancerous tissues, 40 esophageal intraepithelial neoplasia (IEN) tissues and corresponding normal tissues from Jan.2013 to Dec.2013 at the First Affiliated Hospital with Nanjing Medical University were enrolled.The expression of miR-143 was examined by real-time quantitative PCR, and its correlations with clinicopathological features were analyzed.Results: Compared with controls, expression of miR-143 was down-regulated in ESCC and IEN (P<0.05).Expression of miR-143 was correlated with pathological type (P<0.001), but not with gender and age (P>0.05).Expression of miR-143 was correlated with pathological staging, lymph node metastasis and TNM staging (P<0.05), but not correlated with tumor infiltration depth in ESCC patients (P>0.05).Conclusions: Expression of miR-143 is down-regulated in ESCC and IEN tissues, which may be closely related to the development and progression of ESCC, and has the potential to be used as a new target for diagnosis of ESCC.

Results The therapeutic effects in the treatment group was superior to that in control group (X2=13.12, P<0.05) . Conclusion It is effective to treat cerebral hemorrhage with operation combined with Chinese medicines with the functions of stopping endogenous wind, eliminating phlegm and removing blood stasis.

[Objective]To investigate the changes of the hemodynamics and pulmonary histopathology in acute spinal cord injured rats during isoflurane inhalation.[Method]Sixty male SD rats with body weights of 300～330 g were divided into 3 groups:chloral hydrate group,1.5% isoflurane group and 3% isoflurane group.Epidural balloon compression of the T8 spinal cord was performed.Blood pressure and heart rate were monitored during surgery.All animals were sacrificed 10 min after being compressed.The author harvested the lung and recorded lung wet/dry weight ratios(W/D)to assess lung injury severity,and observed the changes of the pulmonary pathology.[Result]Blood pressure in all animals was higher than that of the baseline during the spinal cord injury,but the heart rate was lower than that of the baseline(P0.05).Rats from the 1.5% isoflurane group exhibited severe neurogenic pulmonary edema.The W/D in 1.5% group was significantly higher than those in the other two groups(P

We have transferred the different amounts of the plasmid DNA pCGl, which was constructed by cloning rhGM-CSF gene into the eukaryotic expression plasmid pCDS, directly into the BALB/c mice's quadriceps pretreated with bupivacaine. The result of ELISA confirmed that rhGM - CSF was expressed and secreted in mice of group B injected 60?g of plasmid pCGl, but not in mice of group C injected 30?g of plasmid pCGl. The time for the highest level of rhGM-CSF expression was during the fifteenth to twentieth days after plasmid DNA pCGl was injected. Meanwhile, the results of biological activity detection showed that mice's serum of group B (injected 60?g) had the function of retaining the growth of TF - 1 cells. This demonstrates that the rhGM-CSF in mice's serum of group B has certain biological activity. This Model of animal will blaze a new trail in the treatment and prevention of the leukyopenia.
