Objective This paper is to explore the relationship between the placement of the bone oscillator and bone-conducted thresholds to ASSR stimuli in adults with normal hearing and to investigate the amplitude and the threshold differences to bone-conducted auditory steady-state responses (BC-ASSR) stimuli between single - and multiple-stimulus conditions. Methods Two groups of subjects were selected with 0. 5, 1, 2 and 4 kHz brief tones repeated at the rate of 77, 87, 93 and 101 Hz using a B-71 bone oscillator either in single- or multiple ted no significant differences between mastoid and behind-the-ear placements. The mean and standard deviations of bone-conducted behavioral thresholds to ASSR stimuli at 0.5, 1, 2 and 4 kHz were 62.6±4.8,47.1±4.8,46.8cant difference between the two conditions while the mean and standard deviations of BC-ASSR thresholds at 0.5, 1, 2 and 4 kHz were 96.7±9.7,70.3±11.6,60.6±7.4,52.8±7.2 dB re: 1μN (ppe), respectively. Conclusion The behavioral bone-conducted thresholds to ASSR stimuli with mastoid and behind-the-ear placemen yielded no significant differences. When the stimuli intensity was 50 dB nHL, the amplitudes in single-stimulus condition were significantly higher than those to multiple-stimulus condition. There were no significant differences for BC-ASSR thresholds between single- and multiple-stimulus condition.

Hepatitis B virus(HBV)will become reactive in non-active HBsAg carriers when they are in the immunosuppression status,which is often caused by cytotoxic drugs in chemotherapy or immunosuppressants.Liver damage will be induced in such patients and even liver failure in some patients.Nucleoside analogues could be used in early phase as prophylaxis for reactivation of hepatitis B in immunosuppression and to improve clinical prognosis.

Objective To explore the personality change in patients with epilepsy during the interictal period and the correlation between clinical features and personality change. Methods One hundred and fifteen patients with idiopathic or cryptogenic epilepsy were chosen as the epileptic group and 42 age- and sex-matched healthy subjects served as controls. All participants were evaluated by Mini Mental Status Examination and Brief Psychiatric Rating Scale to ensure the normality of cognition and mental state.Personality was evaluated by adult version of Eysenck Personality Questionnaire (EPQ)in interictal epilepsy patients and healthy controls.Scores of psychoticism (P),extraversion (E),neuroticism (N) and lie (L)were obtained using computer software. Pearson correlation analysis and logistic regression were used to investigate the scores of EPQ and influential factors.Results P and N scores were significantly elevated in epilepsy patients compared with controls ( P scores:50.48 ± 9.55 vs 46.59 ± 7.28,N scores:51.13 ±12.89 vs 46.83 ± 9.40 ; t =2.374,2.266,both P ＜ 0.05 ),while E scores were significantly decreased (51.74 ± 10.74 vs 60.37 ± 9.84;t =- 4.511,P ＜ 0.01 ).There were no significant differences in L scores.Multivariate analysis showed that disease duration was independently correlated to P scores (β =0.043,P＜0.05),while education was correlated to E scores (β =0.109,P ＜ 0.05 ).There were no significant correlations between personality scores,patient age,gender,age of onset,frequency,seizure type,National Hospital Seizure Severity Scale scores,family history,history of status epilepticus and antiepileptic drugs usage.Conclusions High psychoticism and neuroticism and low cxtraversion scores are correlated to patients with epilepsy during the interictal period.Disease duration is an independent risk factor for psychoticism personality,and education level is an independent risk factor for extraversion personality in epilepsy patients.

Objective To observe the effects of a decoction of buzhong yiqi in conjunction with rehabilitation training in relieving post-stroke fatigue.Methods A group of 115 stroke patients was enrolled and randomly divided into a simple rehabilitation group and a combination therapy group.Both groups received conventional rehabilitation treatment and appropriate treatment of any primary diseases.In addition,those in the combination therapy group were given a decoction of buzhong yiqi twice daily for a total of 4 weeks.EMG signals,subjective evaluations of fatigue severity,active rehabilitation exercise duration,motor function and ability in the activities of daily living (ADL) were assessed before treatment and after 4 weeks of treatment.The slope of the surface electromyogram's mean power frequency (KMPF) and median frequency (KMF) were used to quantify fatigue.Subjective fatigue severity was estimated using a fatigue severity scale (FSS).The active rehabilitation exercise lasted,on average,90 minutes daily.The Fugl-Meyer assessment (FMA) was used to evaluate motor function and the modified Barthel index (MBI) ADL ability.Results There were no statistically significant differences between the groups before treatment.After 4 weeks of treatment all the outcomes in both groups had improved (except the FSS scores of the simple rehabilitation group).The KMPF,KMF,FSS,exercise duration,FMA scores and MBI scores in the combination therapy group were all significantly better than those in the simple rehabilitation group.Conclusion Taking buzhong yiqi can significantly improve the clinical effects of conventional rehabilitation training on post-stroke fatigue.It helps relieve fatigue,improve active participation in rehabilitation exercise,and also improve motor function and ADL ability.

Objective To analyze how is the elastography of renal tissue correlated to clinical biochemical indexes and pathological changes in patients with chronic kidney disease (CKD), and toexplore the potential of renal elastography to become a new noninvasive method available for the dynamic monitoring of renal disease progression, as well as its efficacy assessment and prognosis evaluation. Methods Patients admitted to the department of nephrology of the First Affiliated Hospital of China Medical University and received renal biopsy from August 2014 to January 2015 were selected. One hundred and thirteen cases of CKD patients, 61 males and 52 females were enrolled, including 23 cases of IgA nephropathy, 39 cases of membranous nephropathy, 15 cases of minimal change nephropathy and 7 cases of focal segmental glomerulosclerosis. The Young modulus of renal cortex and medulla (YMcortex and YMmedul a) were detected by Aix Plorer type full digital color Doppler ultrasound. The correlations between the YMs and clinical biochemical indicators in blood and urine, and the difference of YMs among different pathological changes in patients with CKD were analyzed by statistics. Results The YMcortex and YMmedul a in CKD patients were higher than those in the control group (all P<0.05); and with the progression of CKD, the YMcortex and YMmedul a gradually increased. The YMcortex in CKD G5 patients was higher than that in CKD G1?3 patients (all P<0.05). The YMmedul a in CKD G3?5 patients was higher than that in CKD G1?2 patients (all P<0.05). The YMcortex was correlated with systolic pressure, serum creatinine, cystatin C, serum albumin, serum phosphorus, calcium and phosphorus product, uric acid, intact parathyroid hormone (iPTH), urinary NAG, estimate glomerular filtration rate (eGFR) and hemoglobin (all P<0.05). The YMmedul a was correlated with systolic pressure, serum creatinine, serum albumin, uric acid, iPTH, urine microalbumin (MA), urinary NAG and hemoglobin (all P<0.05). Serum cystatin C (β=0.485, P=0.018) and uric acid (β=0.418, P=0.039) were independently correlated with the YMcortex. Serum creatinine (β=0.380, P=0.019), uric acid (β=0.482, P=0.004) and smoking (β=0.337, P=0.009) were independently correlated with YMmedul a. The YMcortex and YMmedul a in different pathological types were statistically significant (P<0.001, P=0.003). The YMcortex and YMmedul a in patients with membranous nephropathy and IgA nephropathy were higher than those in the patients with minimal change nephropathy (all P<0.05). The YMmedul a in patients with focal segmental glomerulosclerosis was higher than that in the patients with minimal change nephropathy (P<0.05). The YMcortex in the patients with phases Ⅳ and Ⅴ based on the Lee grading system of IgA nephropathy was higher than that in the patients with phases Ⅱ andⅢ (P<0.05). According the Oxford classification for IgA nephropathy, the YMcortex and YMmedul a in the T1 and T2 patients were higher than those in the T0 patients (P<0.05). The YMcortex and YMmedul a showed no statistically significant differences among different stages of membranous nephropathy. Conclusions The YMcortex and YMmedul a are associated with the progress of renal insufficiency, which may become new indicators for determining CKD progression. The renal ultrasound elastography may become a new non?invasive method for early diagnosing CKD, dynamic monitoring disease progression, and assessing efficacy and prognosis.

OBJECTIVEA component-knockout approach was established to discover active components from traditional Chinese medicine.

METHODAccording to the principle of gene knockout technique, an experiment workflow for component-knockout method was developed, which is distinct from the bio-guided screening method. The differences of therapeutic efficacies between different combinations of individual components were analyzed by some statistical methods including Analysis of Variance (ANOVA), whilst a set of criterias were established to assess active components. By comparing the difference of drug efficacy between the original formulae and the mixture being knockout certain component, the active components can be identified.

RESULTThe presented component-knockout method was applied to discover the active components of Shenmai formulae for the synergistic effects on the cyclophosphamide chemotherapy for S180 tumor-bearing mice. The results indicated that panoxadiol, a type of ginsenosides, were the effective components of Shenmai formulae.

CONCLUSIONA new method for identifying effective components from Chinese medicinal formulae was developed and successfully applied to discover the active components of Shenmai Formulae, which possesses the synergistic actions towards chemotherapy process.
