OBJECTIVETo explore the therapeutic effect of diagnosis and treatment program of integrative medicine (IM) on level 2 hypertension in the young and middle-aged patients and their ambulatory blood pressure.

METHODSA randomized, placebo parallel and controlled, multi-center clinical trial was performed. Totally 199 young and middle-aged level 2 hypertension patients were randomly assigned to the treatment group (99 cases) and the control group (100 cases). All received combined hypotensive treatment program by taking Nifedipine Sustained Release Tablet and Hydrochlorothiazide as basic drugs. Patients in the treatment group additionally took Western medicine (WM) combined Jiangyabao serial drugs (0.31 g per tablet, 2 tablets each time, twice daily), while those in the control group additionally took WM combined simulative agents of Jiangyabao serial drugs (0.31 g per tablet, 2 tablets each time, twice daily). The treatment course was 8 weeks for all, and 24-week follow-ups performed. 24 h ambulatory blood pressure and casual blood pressure, and their efficacies were compared between the two groups, and safety assessed as well.

RESULTSCompared with before treatment in the same group, daytime and night casual blood pressure, as well as 24 h ambulatory blood pressure were all obviously improved in the two groups (P < 0.01). Average diastolic and systolic blood pressures at night decreased more in the treatment group than in the control group with statistical difference (P < 0.05). There was no statistical difference in total efficacies of daytime casual blood pressure or ambulatory blood pressure (P > 0.05).

CONCLUSIONJiangyabao serial drugs combined WM in treating young and middle-aged level 2 hypertension patients showed obvious effect in improving night blood pressure, especially for night diastolic blood pressure.

Objective To investigate the biodistribution,excretion and other pharmacokinetics,of 188Re-1-hydroxy-1,1-ethylidene disodium phosphonate (HEDP) in cancer patients with osseous metastases who were suffering form bone pain. Methods A single dose (20,30,40,and 50 MBq/kg,10 patients in every group) of 188Re-HEDP was administered as a bolus injection,meanwhile dynamic images on patient's chest were collected for 30 min. Anterior and posterior whole-body images were obtained at 1,2,4,5,12,24,36,48,60 and 72 h after injection of 188Re-HEDP. By region of interest (ROI) technology,the curve of time-background corrected counts of left cardiac ventricle could be generated,and the background-corrected counts of various organs and total whole body could be calculated as a geometric mean using the anterior and posterior scans,and transformed to the percentage injected dose ( % ID). Urine was collected after injection of 188Re-HEDP. Counts of urine were measured by γ counter. Analysis of variance and t-test were used. Results Linear relationship of metabolism of 188Re-HEDP was observed in the doses from 20 to 50 MBq/kg,with correlation coefficient r2 = 0. 9376. A two-compartment model was the best fit for metabolism of 188Re-HEDP with the parameters median area under curve (AUC) 3.32 × 105,3.97 × 105,7.83 × 105,8.58 ×105,respectively; median α 0.06,0.05,0.04,0.06 respectively; median β 1.16 ×10-3,1.16 × 10-3,1.03 × 10-3,1.15 × 10 -3 respectively; median A 3591.21,4858.23,5642. 48,4167.05 respectively; median B 293.97,352.95,614.41,1063.82 respectively; median T1/2(α) 12.51,12.83,15.41,12.02 min respectively; median T1/2(β) 595.47,596.50,673.09,600.93 min respectively in the doses of 20,30,40and 50 MBq/kg. 188Re-HEDP was taken up mainly by bone up to 40% ID at 4 h. Urine profile showed that 66.79 % ID was eliminated within 24 h,being its 74% collected along the first 5 h after-administration.Conclusions In the doses of 20,30,40 and 50 MBq/kg,metabolism of 188Re-HEDP presented linear model. Pharmacokinetics of 188 Re-HEDP followed a two-compartment model administrated by blood vessel.Following injection,188 Re-HEDP was taken up mainly by bone and excreted by uropoietic system.

Objective To compare the effect of right ventricular outflow tract (RVOT) and right ventricular apex (RVA) pacing on ventricular systolic synchrony using gated blood pool SPECT (GBPS).Methods A total of 50 patients implanted with pacemaker due to high degree or complete atria-ventricular block were enrolled in the study. Twenty-three patients were RVOT paced ( Group A, n = 23) and 27 were RVA paced (Group B, n=27). Twenty-four patients with malignancy, normal echocardiographic findings and no history of cardiac diseases were scheduled for pre-chemotherapy evaluation of cardiac structure and function and were enrolled as control group ( Group C, n = 24). All patients underwent GBPS imaging and the values of phase angle (PS), mean phase of each wall, standard deviation (SD) of mean phase of each wall, lateral-septal motion delay of left ventricle ( LV Sep-Lat Delay), septal-right ventricular (RV) delay of LV ( LV Sep-RV Delay) and LV-RV Delay were acquired. The parameters of ventricular systolic synchrony among the three groups were compared using one-way ANOVA. Results The mean phase of LV lateral wall in Groups A and B were significantly higher than that in Group C: Group A (120.50 ±40.58) ms; Group B (103.23±28.34) ms; Group C (84.63 ±22.38) ms (F=7.72, P ＜0.05). There was no significant difference between Groups A and B ( t = 1.30, P ＞ 0.05 ). The mean phase of RV in Group A was significantly larger than those in Groups B and C: Group A ( 137.05 ± 39.27) ms, Group B ( 100.85 ± 23.79) ms,Group C (59. 13 ±30.52) ms (F=35.55, P＜0.05). PS, SD and LV Sep-Lat Delay in Groups A and B were significantly higher than those in Group C: (85.73 ± 12.00)°vs (89.85 ± 15.61 )°vs (58.95 ±9.87)°, (27.68±10.66) ms vs (26.15 ±13.02) ms vs (15.63 ±8.35) ms, (25.06±34.23) ms vs (2. 62 ± 60. 31 ) ms vs ( - 23.66 ± 31.39) ms, F = 41.54,8.55,6.81, all P ＜ 0.01 ), however, there was no significant difference between Groups A and B ( t = 0. 68, 0.68, 1.30, all P ＞ 0.05 ). LV Sep-RV Delay and LV-RV Delay were significantly different among the three groups ( LV Sep-RV Delay: Group A (57.60 ±56.77) ms, Group B (6.36 ±61.88) ms, Group C ( -41.89 ±35.78) ms; LV-RV Delay:Group A (47.36 ±42.59) ms, Group B ( 3.08 ± 38.81 ) ms Group C ( - 26.50 ± 20.99 ) ms, F = 20. 32,25.38, both P ＜ 0.01 ). Conclusion Both RVA and RVOT pacing increase the segmental phases detected by GBPS, causing inter- and intra- ventricular asynchrony compared with patients without pacemakers.

pH, affects of different alkaline materials KOH, K 2CO 3, NaOH, Na 2CO 3 on the growth, and NaCl, KCl tolerance of 29 isolates from the saline and alkaline soils in Xinjiang and Qinghai Provinces of China and 1 type strain were studied. Results showed that only a few alkaliphilic actinomycetes were Na +-obligately dependent, and K +-sensitive. Some alkaliphilic actinomycetes were CO 3 2- -sensitive, and NaCl, KCl could inhibit their growth. 4 kinds of alkaline materials had no affect on growth of alkaliphilic Nocardiopsis, and these strains showed high tolerance to NaCl, KCl. So it was presumed that only K + and CO 3 2- obligately dependent alkaliphilic Actinomycetes maybe exist in alkaline environments.

BACKGROUNDMicrovascular decompression (MVD) is a well accepted surgical treatment strategy for trigeminal neuralgia (TN) with satisfying long-term outcome. However, considerable recurrent patients need more effective management. The purpose of this study was to evaluate the effectiveness of radiofrequency thermocoagulation rhizotomy (RTR) on patients with recurrent TN after MVD.

METHODSTotally 62 cases of recurrent TN after MVD undergoing RTR from January 2000 to January 2010 were retrospectively evaluated. Based on surgical procedures undertaken, these 62 cases were classified into two subgroups: group A consisted of 23 cases that underwent traditional RTR by free-hand; group B consisted of 39 cases that underwent RTR under the guidance of virtual reality imaging technique or neuronavigation system. The patients in group A were followed up for 14 to 70 months (mean, 40 ± 4), and those in group B were followed up for 13 to 65 months (mean, 46 ± 7). Kaplan-Meier analyses of the pain-free survival curves were used for the censored survival data, and the log-rank test was used to compare survival curves of the two groups.

RESULTSAll patients in both groups A and B attained immediate pain relief after RTR. Both groups attained good pain relief rate within the first two years of follow-up: 92.3%, 84.6% and 82.6%, 69.6% respectively (P > 0.05). After 2 years, the virtual reality or neuronavigation assisted RTR group (group B) demonstrated higher pain relief rates of 82.5%, 76.2% and 68.8% at 3, 4 and 5 years after operation respectively, while those in group A was 57.2%, 49.6%, and 36.4% (P < 0.05). Low levels of minor complications were recorded, while neither mortalities nor significant morbidity was documented.

CONCLUSIONSRTR was effective in alleviating the pain of TN cases suffering from unsuccessful MVD management. With the help of virtual reality imaging technique or neuronavigation system, the patients could attain better long-term pain relief.
