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.

Human sTNFR1 (soluble tumor necrosis factor receptor 1) gene was amplified by RT-PCR from Hela cells. A recombinant expression vector of sTNFR1-MBP was constructed in pMAL-c2x, and transformed into E. Coli JM109.It was sequenced and confirmed to be identifical to the sTNFR1 gene in data bank. Recombinant protein sTNFR1-MBP was induced by IPTG and purified by Amylose resin Affinity Chromatography. sTNFR1-MBP was binded to sTNFR1's antibody in Western-blotting. From MTT assays, the results showed that sTNFR1-MBP could effectively block the cytotoxicity mediated by TNF?on QSG7701 cells. Annexin V-FITC staining and flowcytometry were used to observe the recombinant protein's anti-apoptosis capacity and the recombinant protein has marked anti-apoptosis effect in vitro.sTNFR1-MBP had good biological activity and it will be employed in further study.

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.

Lemuel Shattuck (1793-1859) was a famous American public health reformer, historian and statistician in the mid-19th century. He introduced statistics into the American system of vital statistics registration and promoted the modernization of the United States demographics. In 1850, he submitted Report of a General Plan for the Promoting of Public and Personal Health to the Sanitary Commission of Massachusetts, which built a blueprint for the future development of the American public health system and laid the foundation for the widespread development of the public health movement in the late 19th century. Shattuck is not only a pioneer in the modern American census, but also a leader in public health in the United States.

OBJECTIVETo compare the difference in the efficacy on gait time cycle of ischemic stroke between yin-yang respiratory reinforcing and reducing needling technique (yin-yang needling) and the conventional acupuncture.

METHODSSixty cases of ischemic stroke were randomized into a conventional acupuncture group and a yin-yang needling group, 30 cases in each one. The basic treatment (the control of blood pressure, blood sugar and blood lipid, the intravenous drops of ginkgo leaf extract and dipyridamole injection and vinpocetine injection) were applied in the two groups. Additionally, in the conventional acupuncture group, the acupoints of the Stomach Meridian of Foot-Yangming [Biguan (ST 31), Liangqiu (ST 34), Zusanli (ST 36), Shangjuxu (ST 37), Xiajuxu (ST 39), etc.] were selected and stimulated with the even needling technique. In the yin-yang needling group, the acupoints of yin meridians such as Zuwuli (LR 10), Xuehai (SP 10), Yinlingquan (SP 9) and Sanyinjiao (SP 6), etc. and the acupoints of yang meridians such as Biguan (ST 31), Liangqiu (ST 34) and Yanglingquan (GB 34), etc. were selected. The reducing manipulation of respiratory reinforcing and reducing technique was applied to the acupoints of yin meridians and the reinforcing manipulation was applied to the acupoints of yang meridians. The kinematics time parameters were determined and compared before and 4 weeks after treatment.

RESULTSAfter treatment, the differences in the gait cycle, the phase time of standing (%), the phase time of single support (%), the phase time of unilateral sway (%) on the affected (healthy) foot and phase time of double support (%) were significant as compared with those before treatment in the patients of the two groups (all P < 0.05), in which, the gait cycle (1.75 +/- 0.21 vs 2.02 +/- 0.37), the phase time of standing (%) on the affected (healthy) foot [(65.41 +/- 5.20)% vs (68.37 +/- 6.24)%, (70.99 +/- 6.47)% vs (74.51 +/- 5.19)%], the phase time of unilateral sway (%) on the affected (healthy) foot [(36.08 +/- 4.86)% vs (33.65 +/- 2.94)%, (31.04 +/- 3.41)% vs (26.77 +/- 2.67)%] and the phase time of double support (%) [(36.91 +/- 5.10)% vs (41.22 +/- 5.39)%] in the yin-yang needling group were improved much obviously after treatment as compared with those in the conventional acupuncture group. The differences in support phase time (%), single support phase time (%) and sway phase time (%) were significant between the affected limb and healthy limb of the two groups after treatment (all P < 0.05).

CONCLUSIONYin-yang respiratory reinforcing and reducing needling technique effectively improves hemiplegic gait movement cycle and walking function in patients of ischemic stroke, which is superior to the conventional acupuncture treatment.
