OBJECTIVETo investigate the therapeutic effect of Yiqi Huaju Recipe (YHR) combined with routine therapy on the blood pressure, the blood pressure variability and other cardiovascular risk factors in hypertension patients complicated with metabolic syndrome (MetS).
METHODSTotally 43 hypertension patients complicated with MetS were recruited in this study and randomly assigned to the treatment group (22 cases, treated with basic routine treatment +YHR) and the control group (21 cases, treated with basic routine treatment + placebo). The treatment course was 12 weeks. Detected were parameters such as 24-h ambulatory blood pressure monitoring (ABPM), body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR), homeostatic model assessment for insulin resistance (HOMA-IR), fasting glycosylated hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), 2 h postprandial plasma glucose (2 h PPG), fasting plasma insulin (FPI), serum lipid, etc.
RESULTSThe anthropometric parameters and plasma glucose levels (except HbAlc) were obviously lowered after treatment than before treatment in the treatment group (P < 0.01, P < 0.05). Besides, better effects were obtained in the WC, WHR, 2 h PPG, FPI and HOMA-IR (P < 0.05). The average blood pressure amplitude, the blood pressure variability, and blood pressure load at any time point were more obviously improved in the two groups after treatment than before treatment (P < 0.01, P < 0.05). Besides, partial indices were better in the treatment group than in the control group (P < 0.01, P < 0.05).
CONCLUSIONSYHR combined with routine therapy exhibited better effect on reducing the blood pressure amplitude, the blood pressure variability, and the blood pressure load in hypertension patients complicated with MetS. It could also effectively decrease the risk of other vascular disease.

Objective To determine whether Fudenine is a novel membrane protein. Methods Green fluorescence protein(GFP)was used to localize Fudenine in vivo. GFP, as a control, was targeted to cytoplasm.Epithelial cell, CBRH7919, and non-epithelial cell, L-6TG, were cultured and transiently transfected by using the lipofectamine reagent. After 48 h, intact cells were examined with fluorescence microscope for Fudenine. Results Reporter plasmid pEGFP-N1, as a control , was expressed and localized to cytoplasm. But Fudenine, driven by the cytomegalovirus promoterenhancer contained in the pEGFP-N1 vector, was overexpressed and targeted to cellular membrane. Conclusions Fudenine is a novel membrane protein. It may play the similar role with its homologues AC133 antigen and prominin in human and mouse.respectively. It might be involved in signaling transduction and regulate blood glucose metabolism in vivo.

Objective To investigate the changes of early and delayed washout rates of 99Tcm-methoxyisobutylisonitrile (MIBI) in ischemic heart disease (IHD), and to explore the value of 99Tcm-MIBI SPECT in evaluating impairment of ischemic myocardial cells. Methods Patients diagnosed of IHD with three-vessel stenosis ( ≥50% ) without myocardial infarction based on angiography (CAG) underwent 99Tcm-MIBI static planar and gated SPECT imaging. The early (90 min after the intravenous injection) and delayed (4 h after the intravenous injection) washout rates of 99Tcm-MIBI and left ventricular ejection fraction (LVEF) of IHD patients and normal subjects were compared using t-test. Linear correlation analysis was performed between the early, delayed washout rates and LVEF measured by gated SPECT. Results Statistically significant lower early washout rate of 99Tcm-MIBI was observed in IHD group than control group: (13.44 ± 2.87 )%vs ( 17.32 ± 4.92) %, t = 2.384, P < 0.05, but higher delayed washout rate of 99Tcm-MIBI was observed in IHD group than control group: (19.24 ±4.71)% vs (15.23 ±3.81)%, t= -2.246, P<0.05. LVEF in IHD group was significantly lower than that in control group: (55.71 ±7.97)% vs (67.75 ±5.43)%, t =-4.418, P <0.01. There were no correlations between the early/delayed washout rates and LVEF, respectively in IHD patients (r = -0.212, P > 0.05; r =0.352, P > 0.05, respectively). Conclusion 99Tcm-MIBI washout rate may reflect myocardial cell impairment due to IHD.

Objective To study the indication, contraindication and short-term clinical effects of stereotactic radiotherapy (X-knife) in lung cancer. Methods A total of 56 cases (Treatment group) of lung cancer were treated with X-knife composing of the modern 3-D treatment planning system and the stereotactic body frame, and SL-75 accelerator. And another 53 cases only treated with routine external radiation served as the control. In treatment group, 42 cases received 50 Gy radiation, at 2 Gy per day, 5 d per week in the upper mediastinum, hilus of lung, below the primary focus first and then underwent X-knife for the primary focuses, and other 14 recurrent and metastatic cases received irradiation of 8-12 Gy per day, 5 d by X-knife alone. Results The actually reexamination rate for 1, 3, 6, and 12 months after X-knife treatment in 78 focuses from 56 cases was 79.5% (62/78), 89.8% (70/78), 87.2% (68/78) and 78.2% (61/78) respectively. The focuses reappeared in 3 months after the treatment and the growth rates of focus in 3, 6, and 12 month after the treatment were 2.6% (2/78), 5.1% and 9% (7/78) respectively. There were 2 focuses received a second treatment with X-knife because no change after the first one. Both the 1-and 2-year survival rates of 36 cases of the primary lung cancer in the treatment group were higher than that of control group (89.1%, 53.9% and 77.4%, 39.6%). Conclusion The stereotactic radiotherapy is of applicable and prospective in the treatment of lung cancer. The indications include: ①As a boost dose in case when primary focus is less than 5 cm after the first external radiotherapy may reduce the exposure of lung tissue to x-ray and the occurrence of radiation pneumonia; ②Treatment for the recurrence after radiotherapy and operation; ③Radical treatment for the metastatic focus less than 5 cm. Attention must be paid to when multiple treatment is carried on the volume of the focus, the Karnofsky scores and the general condition when stereotactic radiotherapy combined with X-knife for lung cancer.
