Chinese Journal of Comparative Medicine 2015;(12):54-58
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.

Chinese Journal of Geriatrics 2012;31(10):847-849
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.

Chinese Medical Equipment Journal 1989;0(03):-
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 study the value of the preoperative detrusor contractility to the outcome assessment of prostatectomy for benign prostatic hyperplasia (BPH).Methods A total of 109 patients with BPH were analyzed.Their ages ranged from 62 to 83 years with a mean of 71 years.All patients underwent urodynamic study to confirm a diagnosis of BOO preoperatively.Further more, their BOO was not caused by nervous, endocrine or other diseases.Pateints were divided into two groups based on maximum detrusor contractility.Group Ⅰ (n =61, BPH with maximum detrusor contractility ≥ 40 cm H2O, 1cm H2O =0.098 kPa) underwent TURP or open surgery, respectively.Group Ⅱ (n =48, BPH with maximum detrusor contractility ≤ 20 cm H2O ) underwent TURP and suprapubic punctural cystostomy simultaneously,the bladder fistula was kept open continuously for at least two weeks postoperatively.The difference in outcome between the two grous was assessed by using urodynamic parameters including maximum detrusor contractility, Qmax and residual urine at one and three months postoperatively respectively.Student's t-test was used to compare the result for normally distributed data and Wilcoxon's signed-ranks test for skewed data in this study.Results There was significant difference in preoperative maximum contractility, Qmax between group Ⅰand groupⅡ (78.4 ±37.0 cm H2O) vs (19.2 ±5.4 cm H2O)(P<0.01), (7.6±2.2 ml/s) vs (2.5 ± 1.1 ) ml/s (P < 0.05) respectively.Although there was significant difference at one month postoperatively in Qmax (17.4 ±2.9)ml/s vs (12.5 ±2.0)ml/s (P<0.05), no significant difference was found in Qmax between the two groups after three months ( 18.3 ±2.8 ml/s) vs ( 15.2 ± 1.8)ml/s (P > 0.05).Conclusions The Qmax may improve and the impaired detrusor recovered gradually after the BOO was removed.Performing an operation on patients with BOO accompanied with detrusor underactivity may be useful to recover detrusor contractility.

ObjectiveTo observe the effect of the doctor-led telephone interview on the state of anxiety for outpatients with epilepsy.Methods100 outpatients with epilepsy and state of anxiety were divided into two groups: intervention group (doctor-led telephone interview) and control group (outpatient face-to-face visit in the epileptic clinic), 50 cases in each group. Doctor-let semi-structured telephone interview was performed in the intervention group, while routine face-to-face interview in outpatient was performed in the control group for 6 months. Self-rating Anxiety Scale (SAS) was used to assess the anxiety state before and 6 months after intervention. The state of anxiety and the patients' contents in the two groups were analyzed.ResultsThe scores of SAS in two group decreased 6 months after intervention and the intervention group was better than the control group.ConclusionThe doctor-led telephone interview can improve the state of anxiety for the patients with epilepsy.

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.
