Objective:To analyze the depression incidence in premenopausal or postmenopausal women, find out the countermeasures to control or eliminate depression. Methods:Randomly divided the menopause group and premenopausal group in 724 patients who were assessed using Zung depression scale and venous blood determination of endocrine hormone FSH, LH, E2. Zung score≥40 points can diagnose depression. Results:The incidence in premenopausal group of climacteric depression was 13.3%, and postmenopausal group was 5.6%. The incidence of climacteric depression premenopausal group was obviously higher than that after menopause (x2=12.797, P<0.05). Conclusion:Menopause depression patients often have some physical or mental factors as incentive, spirit and body disease, etc.;Patients often change in physical and psychological. So the comprehensive care in the biological, psychological and social are necessary.

Objective To study the effect of myocardial infarction induced by distal left ascending artery occlusion on left ventrieular(LV) synchronism. Methods Routine echocardiography and vector velocity imaging were performed within 2 hours before and 7-14 days after myocardial infarction by occluding distal left ascending coronary arteries in experimental pigs. Routine eehocardiographie parameters of LV, including end diastolic and systolic diameters, volumes, and spherical indexes were measured or calculated. Six segmental peak systolic velocity, strain and strain rate were compared between pre- and post-myocardial infarction. Results After myocardial infarction, LV end diastolic, end systolic long diameter and end systolic volume increased with decreased ejection fraction. With the 6 segmental systolic velocity, strain and strain rate significantly reduced,the mean 6-segmental time to peak strain rate delayed significantly. Conclusions Abnormal synchronism after myocardial infarction may aggravate LV systolic dysfunction.

Objective To investigate the antitumor effect of specific cytotoxic T lymphocytes induced by renal cell carcinoma multiple antigen peptide dendritic cell (DC) vaccine in vitro. Methods Dendritic cells were induced by hGM-CSF,hIL-4 from blood.Peptide of renal cell carcinoma cell line (RCC786-0)was got by citrate-phosphate buffer elution.Peripheral blood mononuclear cell was cultured.Multiple antigen peptide DC cell vaccine was obtained by acid-eluted peptide pulsed DC.The tumor antigen specific CTL was generated from activated T cell by vaccine.Killing activity of the tumor antigen specific CTL was activated by vaccine. Results Antigen peptide DC cell vaccine could show a strong cytotoxic activity of CTLs(31.93±5.05%),which was much higher than control groups(5.88±2.26%,8.03±6.70%,9.70±2.09%,9.35±3.58%). Conclusion Renal cell carcinoma antigen peptide DC vaccine could show a high antitumor effect in vitro.

Objective To assess the therapeutic effect of music- regulated laser therapy on mild and moderate primary hypertension (PH) so as to provide clinical evidence for the development of an effective non-drug therapy for hypertension. Methods One hundred mild and moderate PH patients were divided into obser-vation ( n = 50 ) and control groups ( n = 50 ) according to their stage of hypertension. There were two phases of treatment with 6 weeks in each phase for a total of 12 weeks. In the first phase, patients in the observation group received music-regulated laser therapy while the control group received drug therapy. In the second phase, the treatments were reversed, with the observation group receiving the drugs. The blood pressure and quality of life (QOL) of all the patients was evaluated after each phase. Results Before therapy there were no significant differences in average blood pressure or QOL between the groups. After the first phase, systolic blood pressure (SBP) and diastolic blood pressure (DBP) had been reduced significantly in both groups, but the decrease was significantly greater in the control group. The score on each item of the QOL evaluation was not significantly different between the two groups. After the second phase, blood pressure had decreased further in the observation group, but no significant change was observed in the control group, and there was no significant difference in blood pressure between two groups. The scores on each item of the QOL evaluation were not significantly different between the two groups, but average somatic symptoms, healthy and pleasant feelings, task perform-ance and life satisfaction were significantly ameliorated in both groups. Conclusions Music-regulated laser therapy can lower the blood pressure of mild and moderate PH patients effectively. Compared with antihyperten-sion drugs, music-regulated laser therapy provides a weaker effect in lowering blood pressure, but plays an e-quivalent role in improving the QOL of patients.

Objective Using surface electromyography (sEMG) techniques to investigate the patterns of frequency domain indexes of sEMC signals recorded from adolescent idiopathic scoliosis (AIS) patients' paraspinal muscles. Methods Twenty-five AIS patients were enrolled. All the patients undertook the Biering Sorensen test ( BST) ,the object-lifting test and a semi-bridge test, the ME3000P sEMG instrument was applied to record the electric activities of paraspinal muscles (convex/concave) of all subjects, and the time domain indexes such as averaged EMG(AEMG)and spectrum area(SPA) were analyzed, values in three tests were compared with one way ANOVA. Results The differences of AEMGs and SPAs on both convex and concave sides among the three tests showed no statistical significances (P = 0. 10,0.23, 0. 24 and 0. 45, respectively). Conclusions Any of the Biering Sorensen test( BST) , the object-lifting test or the semi-bridge test can be used to test the electric activities of paraspinal muscles (convex/concave) of AIS patients.

Objective To explore the relationship between ULI43 sequence variability and clini-cal disease. Methods UL143 from samples obtained from suspected congenitally human cytomegalovirus (HCMV) infected symptomatic infants were PCR amplified and sequenced. Results There were not too much sequence variability of UL143 compared with Toledo. But no one was completely identical to Toledo, and all UL143 ORFs were shorter than Toledo for frame-shift. Conclusion HCMV-UL143 existed in moat of low passage isolates and sequences were variable. No obvious linkage was observed between UL143 poly-morphisms and outcome of suspected congenital HCMV infection.

BACKGROUND:At present, a large number of studies have proved that the expandable intramedul ary nail and interlocking intramedul ary nail are effective in treatment of limb fractures. However, for the treatment of tibial fractures, the advantages and disadvantages of the two kinds of fixation methods are stil inconclusive. OBJECTIVE:To systematical y review the effectiveness and safety of expandable intramedul ary nail and interlocking intramedul ary nail for treatment of tibia fracture. METHODS:We searched PubMed, Embase, The Cochrane Library (Issue 1, 2015), CBM, CNKI, VIP and WanFang Data for articles concerning randomized control ed trials on expandable intramedul ary nail versus interlocking intramedul ary nail published from inception to January 1, 2015. The key words were“tibia, fracture, tibia fracture, tibia fractures, expandable intramedul ary nail, expandable nail, intramedul ary nail, interlocking intramedul ary nail”. Meta-analysis was performed using RevMan 5.2 software. RESULTS AND CONCLUSION:Ten randomized control ed trials involving 574 patients were included. The results of meta-analysis showed that, compared with interlocking intramedul ary nail, expandable intramedul ary nail was shorter in operation time [MD=-23.42, 95%CI (-26.94,-19.90), P<0.000 01], less in intraoperative hemorrhage [MD=-47.64, 95%CI (-52.21,-43.09), P<0.000 01], less in fluoroscopy times [MD=-1.40, 95%CI (-1.49,-1.30), P<0.000 01], shorter in union time [MD=-30.84, 95%CI (-35.27,-26.41), P<0.000 01], and less in incidence of complications [OR=0.20, 95%CI (0.10, 0.40), P<0.000 01]. The Johner-Wruh scores showed on significant difference. These findings suggest that expandable intramedul ary nail for tibia fracture has more advantages than interlocking intramedul ary nail. That is to say, the expandable intramedul ary nail is an improved nail of interlocking intramedul ary nail, but a large sample of high quality randomized control ed trials are stil needed to confirm the conclusion.

BACKGROUND:At present, a large number of studies have proved that the discectomy and interbody fusion are effective in treatment of lumbar disc herniation. But for the treatment of lumbar disc herniation with Modic change, the advantages and disadvantages of above two kinds of surgical methods are stil inconclusive. OBJECTIVE: To systematicaly review the effectiveness of discectomy versus interbody fusion in treatment of lumbar disc herniation with Modic change. METHODS: We searched PubMed, Embase, The Cochrane Library (Issue 2, 2015), CBM, CNKI, VIP and WanFang database for randomized controled trials on discectomyversus interbody fusion for lumbar disc herniation with Modic change from inception to May 1st, 2015. Clinical outcomes were back pain Visual Analog Scale, leg pain Visual Analog Scale, Oswestry Disability Index, lumbar Japanese Orthopaedic Association score, the number of cases affecting complications, and MacNab criteria. Meta-analysis was performed using RevMan 5.2 software. RESULTS AND CONCLUSION:Nine randomized controled trials were included, involving 945 patients. The results of meta-analysis showed that compared with discectomy group, back pain Visual Analog Scale was lower [MD=0.81, 95%CI (0.69, 0.92),P < 0.000 01]; Oswestry Disability Index was lower [MD=2.07, 95%CI (1.62, 2.52),P< 0.000 01]; lumbar Japanese Orthopaedic Association score was higher [MD=-2.32, 95%CI(-4.32,-0.32),P=0.02] in the interbody fusion group. No significant difference in leg pain Visual Analog Scale and MacNab criteria outcomes was detected between both groups. These findings verified that interbody fusion was safer and more effective for lumbar disc herniation with Modic change, compared with discectomy.

Objective:To study the nephrotoxicity induced by triptolide ( TP) on MDCK cell model and investigate its effect on oxidative stress. Methods:Aristolochic acid was chosen as the positive control. After the MDCK cells were incubated with 0. 5, 5, 50 and 500 nmol·L-1 TP for 24h, MTT method was used to observe the cell inhibiting rate and lactate dehydrogenase (LDH) release test was used to detect the cell membrane damage caused by TP. The cell morphology was observed under an inverted microscope. After the MDCK cells were incubated with 500 nmol·L-1 TP respectively for 30min, 1h, 2h, 4h and 6h, the level of reactive oxygen species ( ROS) was detected using 2′,7′-dichlorodihydro-fluorescein diacetate ( DCFH-DA) as the fluorescent probe. Results:Compared with those of the negative control group, the cell inhibiting rates and the relative LDH release rates in TP-treated group were increased sig-nificantly(P<0. 01). The cells in TP-treated group were creased, turned into the round shape and began to shed off. After the MDCK cells were incubated with TP for 30min, the level of ROS reached the highest value, and then began to decrease (P<0. 01). Conclu-sion:TP can induce the toxic effects on MDCK cells and the mechanism may be related to oxidative stress.
