Objective To observe the effect of Huolisu oral liquid combined with mirtazapine tablets on the expressions of NE and 5-HT in the patients with depression,and explore the therapeutic efficiency. Methods 75 patients with depression were randomly divided into a study group with 43 cases,which were treated with Huolisu oral liquid and mirtazapine tablets and a control group with 32 cases,which were only treated with mirtazapine tablets The Hamilton depression scale(HAMD)score, serum NE,and 5-HT were detected in the patients before the treatment and 4 and 8 weeks after the treatment separately. Results Before treatment,there were no statistical significance in HAMD score,serum depression NE and 5-HT(t=0.501, 0.520, 0.611,P>0.05). After treated for 4 and 8 weeks, compare with the control group, HAMD score was decreased(t=1.829、2.263, P<0.05), serum 5-HT was increased(t=2.119, 2.870, P<0.05),and NE was increased in the study group(t=2.264, 2.705,P<0.05). Conclusion Huolisu oral liquid combined with mirtazapine tablets can significantly decrease HAMD score,and increase serum NE and 5-HT level. The treatment can improve the depression symptoms in the patients with depression obviously.

Objective To analyze and discuss the value and significance of coronary artery bypass grafts in the same period of heart valve replacement in the process of the coronary heart disease with heart valve disease treatment, in order to improve the effect of treatment and reduce the incidence of adverse events. Methods 60 cases with coronary heart disease with heart valve disease , which admitted in our hospital during February 2013-February 2015, were selected as the research objectaccording to random number table method and divided into the-experimental group and the control group , each group of 30 cases according to the principle of double blind control. The experimental group was given the coronary artery bypass grafts in the same period of heart valve replacement and the control group was given the coronary artery bypass grafts without heart valve replacement. The curative ef-fects of different schemes and effects on cardiac function after surgery of the two groups were compared. Results After statistical analysis found thatthe observation indexes of the control group was significantly increased compared with the experimental group, the difference was significant statistically significant (P<0.05). The postoperativecar-diac function indexes of the experimental group was significantly improved then control group , the difference was significant statistically significant (P<0.05). Conclusion Coronary heart disease with heart valve disease in the process of treatment can also take heart valve surgery combined coronary artery bypass surgery. By preoperative and postoperative symptomatic treatment, intraoperative protect myocardium, can effectively prevent and reduce the op-eration of various complications, which is worthy of clinical popularization and application.

Objective To find out the bioactive constituents in the stem of Lonicera japonica and to carry out a systematic study on the chemical constituents of the plant. Methods Three compounds were isolated from the plant by means of solvent extraction and column chromatography, and their structures were elucidated by spectral analyses. Results All these compounds were identified as luteolin (Ⅰ), loga-nin (Ⅱ), r-1-(4-hydroxy-3-methoxy-phenyl)-trans-2, cis-3-dihydroxymethyl-7, 8-dihydroxy-6-methoxy-1, 2, 3, 4-tetrahydro-naphthalene (Ⅲ), respectively. Conclusion Compound Ⅲ is a new compound named as japenol.

Objective: To investigate the relationship between the c-Jun N-terminal kinase (JNK) pathway and lung-resistance protein (LRP). Methods:A549 cells were treated with various concentrations of CDDP for 72 h. The LRP mRNA expression was then analyzed using reverse transcription PCR (RT-PCR). LRP, JNK, and P-JNK were analyzed by Western blotting. The A549 cells were then pretreated with SP600125 (2 μg/ml to 4 μg/ml ) for 1 h. Afterward, CDDP (16 μg/ml) was added into the culture for 72 h. A Cell Counting Kit-8 was used to investigate the sensitivity of CDDP to the A549 cells. Flow cytometry was used to detect the apoptosis rate. The LRP mRNA expression was analyzed using RT-PCR. LRP, JNK, and P-JNK were analyzed by Western blotting. Results:CDDP in-duced the mRNA and protein expression of both LRP and P-JNK in a dose-dependent manner. Pretreatment with SP600125 enhanced the sensitivity of CDDP to the A549 cells and increased the apoptosis rate. However, the LRP mRNA and LRP expression in the pre-treated cells was lower than that in the presence of CDDP alone. Conclusion:In A549 cells, CDDP induces the LRP expression via the JNK pathway. This result suggests that lung cancer therapy can be improved by the addition of CDDP to inhibit the JNK signaling path-way.

Objective To evaluate the pharmacokinetic profiles of lopinavir(LPV) in Chinese HIV-infected patients.Methods A total of 16 patients were enrolled in the LPV pharmacokinetic study.Blood samples were collected before LPV intake and 0.5,1.0,1.5,2.0,2.5,3.0,4.0,6.0,8.0,10.0,12.0 h after administration.Serum level of LPV was determined by the developed high performance liquid chromatography (HPLC) method.The pharmacokinetic profiles were assessed by WinNonlin software.Results The non-compartment model pharmacokinetic (PK) parameters were as follows:the peak time of LPV (Tmax) (3.88 ± 0.23) h,maximum plasma concentration (Cmax) (10.36 ± 3.42) mg/L,minimum plasma concentration (Cmin) (2.18 ± 0.34) mg/L,the 24 h area under plasma-concentration-time curve (AUC0-24) (116.22 ± 15.68) mg · h · L-1,half life(T1/2) (4.5 ± 0.13) h,and clearance rate (CL/F) (3.44 ± 1.34) L/h respectively.Conclusions The pharmacokinetic profiles of LPV in Chinese HIV-1 infected patients demonstrate lower Cmin than those of reported studies,while other parameters are similar.Patients should be educated for compliance based on the narrow gap between Cmin and minimum effect concentration.

Objective To observe the effect and mechanism of Pingwei Xiaodao Capsule (Capsule for functional dyspepsia) on the gastric motility of functional dyspepsia (FD) model rats.Methods Totally 60 wistar rats were randomized into a blank control group (normal group),model group,domperidone group,Pingwei Xiaodao Capsule large,medium,and small dosage groups.Except for the normal group,the rats of all other groups were irritated by clamping tails for making FD models.Then,the treatment was given for 7 days.The comparative observation was carried out on the gastric interdigestive myoelectric complex (IMC),slow wave frequency variation coefficient,abnormal rhythm index,and gastric emptying rate of all groups.Results Compared with the model group,the IMC period of domperidone group and all Pingwei Xiaodao Capsule groups was shortened,phase Ⅲ prolonged,incidence of phase Ⅲ increased(P

Distortion product otoacoustic emission (DPOAE) signal can be used for diagnosis of hearing loss so that it has an important clinical value. Continuously using sweeping primaries to measure DPOAE provides an efficient tool to record DPOAE data rapidly when DPOAE is measured in a large frequency range. In this paper, locally weighted least squares estimation (LWLSE) of 2f1-f2 DPOAE is presented based on least-squares-fit (LSF) algorithm, in which DPOAE is evoked by continuously sweeping tones. In our study, we used a weighted error function as the loss function and the weighting matrixes in the local sense to obtain a smaller estimated variance. Firstly, ordinary least squares estimation of the DPOAE parameters was obtained. Then the error vectors were grouped and the different local weighting matrixes were calculated in each group. And finally, the parameters of the DPOAE signal were estimated based on least squares estimation principle using the local weighting matrixes. The simulation results showed that the estimate variance and fluctuation errors were reduced, so the method estimates DPOAE and stimuli more accurately and stably, which facilitates extraction of clearer DPOAE fine structure.
