ObjectiveTo investigate the effect of β-adrenergic receptor(β2AR) stimulation on vascular smooth muscle cell apoptosis in physiological state and receptor overexpression model.Methodsβ2AR overexpression model was established by transgenic techniques. Hoechst 33342 staining as well as flow cytometer(FCM) detected were chosen to measure the incidence of vascular smooth muscle cell apoptosis.ResultsVascular smooth muscle cell exhibited significantly fewer viable cell rate when stimulated with β2AR agonist isoproteronol for 48 hours compared with control (P<0.01),while no difference at the time point of 24 hours. Much fewer viable rate detected by FCM and high apoptotic rate by Hoechst staining were observed when VSMCs overexpressing β2AR were stimulated with isoproteronol for 24 hours (P<0.01).ConclusionStimulation of physiological and overexpressing β2AR could induce apoptosis of vascular smooth muscle cell.

Objective To investigate the effects of c?myc promoter binding protein 1(MBP?1)gene on the proliferation of human Saos?2 osteo?sarcoma cells in vitro. Methods Saos?2 cells were divided into three groups:blank control group(untransfected cells),negative group(cells transfected with missense sequence)and experimental group(cells transfected with MBP?1 shRNA). Two MBP?1 shRNA sequences and one neg?ative control shRNA sequence were designed ,synthesized and cloned into pSIREN?retroQ plasma. Then the recombinant plasmids were construct?ed and transfected into human Saos?2 osteosarcoma cells by Lipofectamine 2000. The expressions of MBP?1 mRNA and protein in Saos?2 cells were detected by real?time PCR and Western blot ,respectively. The effects of altered expression of MBP?1 on cell proliferation were measured by CCK?8 cell proliferation assay. The expressions of cyclin D1 and cyclin E in Saos?2 were determined by Western blot. Results PCR and sequenc?ing results indicated that the recombinant plasmids pSIREN?retroQ was constructed. The relative expression level of MBP?1 mRNA in the MBP?1 siRNA transfection group was significantly decreased than that in blank control group(P<0.05). Compared with the blank control group,the ex?pression levels of MBP?1 protein in the experimental group also significantly decreased. The proliferation abilities of Saos?2 cells at 48,72,and 96 hours after MBP?1 siRNA transfection were significantly increased than those in the blank control group(P<0.05). Compared with the blank con?trol group,the expression levels of cyclin D1 and cyclin E protein in the experimental group also significantly increased(P<0.05). Conclusion Knockdown of the expression of MBP?1 gene promotes the proliferation of human Saos?2 osteosarcoma cells. MBP?1 gene may become the new tar?get of gene therapy for osteosarcoma.

Objective To silence human gene Set7/9 and screen out stable transfection cell line in hepatocellular carcinoma cell line HepG2 so as to investigate the impact of down-regulation of Set7/9 in cell line HepG2 and provide experimental foundation for studies on the effect of set7/9 in HepG2.Methods The target oligo was designed and synthesized;shRNA interference vector and the control vector were constructed and transfected into HepG2 cells;the stable transfection cells were screened out.Then Real-time PCR and Western blot were performed to detect the silence of Set7/9 according to both gene expression and protein expression level. Results The shRNA interference vector was constructed and transfected into HepG2 cells successfully.Compared with that in the negative control group,the expression of Set7/9 was dramatically downregulated (P < 0.05 ). Meanwhile,the expression of related protein Sirt1 and Suv39h1 was upregulated 8.4 folds and 1.1 fold, respectively.Conclusion Downregulation of Set7/9 expression can upregulate Sirt1 and Suv39h1,suggesting that Set7/9 may affect the activity of HepG2 cell lines.

This study was aimed to evaluate the clinical effect and safety of Chinese medicine treatment of lumbar disc herniation with qi-tonifying, stasis-resolving and kidney-tonifying method. The randomized con-trolled trial (RCT) was applied in the study to evaluate the clinical effect of qi-tonifying, stasis-resolving and kidney-tonifying method in the treatment of lumbar disc herniation . A total of 122 lumbar disc herniation pa-tients were randomly divided into the treatment group ( n = 61 ) and the control group ( n = 61 ) . Chinese medicine treatment with the qi-tonifying, stasis-resolving and kidney-tonifying method was applied in the treatment group . And Celecoxib and Methycobal were orally administered in the control group . Then , the VAS scores, JOA scores, Oswestry disability index (ODI) were recorded and analyzed pre-treatment, four weeks af-ter treatment and the twelfth week of follow-up in order to evaluate the clinical effect . Adverse reactions were also observed and recorded at the same time to give a comprehensive evaluation on its safety . The results showed that there were no significant differences between the treatment group and control group in the baseline data before treatment . Hence , data from two groups were comparable . Compared with pre-treatment , the VAS scores and ODI scores were obviously reduced in both groups after four-week treatment . The JOA scores were increased obviously ( P < 0 . 05 ) . There were no statistical differences on ODI scores and JOA scores between two groups . The VAS scores of the treatment group were obviously higher than the control group ( P < 0 . 05 ) . In the twelfth week of follow-up , the VAS scores , ODI scores and JOA scores had increasing tendency in
both groups . There were no statistical differences between two groups . There were no statistical differences on the total effective rate between two groups . In the treatment group , four patients received surgery , four cases lost to follow-up , and four cases with mild adverse event . In the control group , six patients received surgery , three cases lost to follow-up , and two cases with mild adverse event . It was concluded that the RCT of Chi-nese medicine treatment of lumbar disc herniation with q i-tonifying , stasis-resolving and kidney-tonifying method received same clinical effect as the combination of Celecoxib and Methycobal . The Chinese medicine treatment can effectively relieve pain degree of lumbar disc herniation , improve function of the lumbar vertebrae and improve the daily life and social activity ability of patients. The short-term follow-up effects were con-firmed . However , the long-term efficacy still requires further study .

ObjectiveTo investigate the effect of simvastatin on severe complications and prognosis of subarachnoid heamorrhage (SAH).Methods98 cases with SAH were randomly divided into the treatment groups and control group (finally, there were 32 cases in treatment group, 48 cases in control group). Patients in treatment group were given simvastatin 20 mg/day, and those in control group were treated with routine therapy. The incidences of cerebral vasospasm, hydrocephalus, rebleeding and mortality between the two groups were compared.ResultsThe incidence of hydrocephalus of treatment group was 3.13%; that of control group was 18.7%, there was a significantly difference between two groups (P<0.05). There were no significant differences for incidences of cerebral vasospasm, rebleeding and mortality between two groups (P>0.05).ConclusionSimvastatin can reduce the occurrence of hydrocephalus after SAH.

ObjectiveTo investigate the incidence of skeletal and/or articular malformations in central core disease (CCD) patients, and their risk of malignant hyperthermia (MH) in orthopedics. Methods28 unrelated patients with central core disease collected in the past 23 years were analyzed retrospectively. Results22 patients showed limb muscle weakness, while 6 patients didn't show any clinical symptom. Skeletal and/or articular malformations appeared in 21 patients, including joint contracture in 11, joint dislocation in 9, scoliosis in 12, lordosis in 5 and thoracic deformity in 1. 6 of the 10 patients could not endure orthopedic operation because of MH attack or dubitable MH attack. Calcium-induced calcium release (CICR) test performed on other 8 patients with MH family history or MH attack showed all those patients were MH susceptibilities. ConclusionSkeletal and/or articular malformations are common in CCD, as well as MH attack in orthopedics.

This paper presents and discusses the liquid density sensing potential of a delay line Lamb-wave sensor configuration, where Lamb wave is excited only by interdigital transducer (IDT), without membrane when fabricated. An optimized cut orientation and the normalized thickness of substrate by using genetic algorithm is presented to improve the sensitivity of the sensor and to get low noise. Experimental measurements performed on Lamb-wave device fabricated from Y-Z LiNbO3 in a delay line configuration are found to be in agreement with theoretical calculations.
