Objective To evaluate the therapeutic effect of modifiedHuanglian-Jiedudecoction for resistant hypertension and explore its possible mechanism.Methods A total of 90 patients with resistant hypertension were recruited and randomly divided into a treatment group and a control group, 45 patients in each group. The control group was treated with oral administration of irbesartan and hydrochlorothiazide tablets and controlled-release nifedipine tablets, while the treatment group was further added modifiedHuanglian-Jiedu decoction for 4 weeks. Plasma endothelin (ET) and calcitonin gene-related peptide (CGRP) were measured by radioimmunoassay.Rusults The total efficiency according to the TCM syndrome in the treatment group was 86.7%(39/45) which was higher than 64.4%(29/45) in the control group(χ2=4.873,P=0.027). The systolic blood pressure (SBP) and diastolic blood pressure (DBP) decreased after the treatment in both groups ( SBP in the treatment group: 119.26 ± 9.34 mmHgvs.172.11 ± 10.52 mmHg,t=25.201,P<0.01; DBP in the treatment group: 78.18 ± 7.21 mmHgvs.111.12 ± 11.16 mmHg,t=16.631, P<0.01; SBP in the control group: 145.21 ± 7.56 mmHgvs.171.32 ± 11.15 mmHg,t=13.002,P<0.01; DBP in the control group: 93.57±8.13 mmHgvs. 109.89 ± 12.21 mmHg,t=7.463,P<0.01), while the decrease of SBP (t=14.487,P<0.01) and DBP (t=9.501, P<0.01) in the treatment group was more greater than those in the control group. The control rate of blood pressure in the treatment and control groups were 73.3% (33/45) and 55.6% (25/45), respectively, there had no significant difference (χ2=2.376,P=0.123). The plasma ET in the treatment group was significantly decreased than that in the control group (75.68 ± 10.67 ng/Lvs.112.79 ± 12.26ng/L;t=15.317,P<0.05), and CGRP significantly increased (49.87 ± 4.75 ng/Lvs.33.87 ± 7.89 ng/L;t=11.654,P<0.05).Conclusion Modified Huanglian-Jiedudecoction may have some therapeutic effect for resistant hypertension, its mechanism may be involved in ET decreasing and CGRP increasing.

Objective To evaluate the accuracy and feasibility of time-resolved immunofluorometric assay (TRI FA) for detection of HBsAg based on Abbott automated chemiluminescence immunoassay(CMIA),so as to carry out this project in primary hospitals,and provide reference for individual antiviral strategy and prediction of therapeutic effect.Methods Serum of 157 patients infected with hepatitis B virus were detected with CMIA and TRIFA,specimens with HBsAg titers exceeding the detection limit were firstly diluted,then performed quantitative analysis.HBsAg levels were divided into 4 groups:≤100 IU/mL,101-1 000 IU/mL,1 001-20 000 IU/mL,and ＞ 20 000 IU/mL,quantitative correlation between two methods was analyzed.Results The linear regression equation of two methods was Y=2.323X-896.3,correlation coefficent r=0.943,P＜0.001.CMIA was as a reference,4 groups were divided for analysis,results showed that when detected specimens was at low concentration of HBsAg,TRIFA value was low compared with CMIA method,while detected specimens was at high concentration of HB sAg,CMIA value was high,two reagents had good consistency in the detection of different concentrations of HBsAg(both P＜0.05),when concentration was at 1 001-20 000 IU/mL,consistency was the best.Conclusion The accuracy of two reagents in the quantitative detection of HBsAg is similar,and the best correlation of detection value is 1 000-20 000 IU/mL.TRIFA assay has wide application for its low-cost and easy to be operated,which is especially suitable for primary hospitals.

Objective To evaluate the minimally invasive treatment of calcaneal fractures of Sanders Ⅱ &Ⅲ by closed reduction or a sacral sinus arc-shaped minimally invasive incision under subtalar arthroscopy assisted by a self-designed cervical retractor and a self-designed reducer to expose and assist the reduction followed by internal fixation with hollow nails and Kirschner wires.Methods From June 2016 to February 2018,53 patients (60 feet) were treated at Department of Hand and Foot Surgery,Central Hospital of Linyi for closed intra-articular calcaneal fractures.Of them,24 (28 feet) received the minimally invasive treatment and 29 (32 feet) open surgery via the conventional lateral L-shaped incision.The 2 groups were compared in terms of B(o)hler angle,Gissane angle,and the width,length and height of the calcaneus before operation,one week after operation and at the final follow-up,as well as in terms of preoperative preparation time,operation time,surgical bleeding volume,incision complications,subtalar joint stiffness,and anklehindfoot score of the American Foot and Ankle Surgery Association (AOFAS).Results The 2 groups were comparable because there were no significant differences between them in the preoperative general data (P ＞ 0.05).All the patients were followed up for 10 to 22 months (average,16 months).The B(o)hler angles,Gissane angles,and the widths,lengths and heights of the calcaneus after operation and at the final follow-up were significantly better than the preoperative values in the minimally invasive group (all P ＜ 0.05).The preoperative preparation time (2.5 d ± 1.2 d) and operation time (62.6 min ± 6.3 min) in the minimally invasive group were significantly shorter than those (7.6 d ± 3.5 d and 85.9 min ± 9.7 min) in the conventional group (P ＜ 0.05),the surgical bleeding volume in the former (30.5 mL ± 3.8 mL) was significantly smaller than that in the latter (80.9 mL ± 8.3 mL) (P ＜ 0.05),and the rates of incision complications (0) and subtalar joint stiffness (10.7％) in the former were significantly lower than in the latter (9.4％ and 43.7％) (P ＜ 0.05).However,there was no significant difference between the 2 groups in the AOFAS anlle-hindfoot score (92.8 ± 5.9 versus 89.5 ± 7.5) (P ＞ 0.05).Conclusion The minimally invasive treatment of calcaneal fractures of Sanders Ⅱ & Ⅲ by closed reduction or a sacral sinus arc-shaped minimally invasive incision under subtalar arthroscopy assisted by a self-designed cervical retractor and a self-designed reducer to expose and assist the reduction followed by internal fixation with hollow nails and Kirschner wires can lead to satisfactory clinical results,because this method shortens significantly the time for hospitalization and leads to less invasion,fewer complications,accurate reposition and reliable fixation.

OBJECTIVE: To determine whether time-resolved immunofluorescence assay (TRIFA) shares the similar accuracy and specificity with automatic chemiluminescence immunoassay (CMIA) in analyzing HBeAg levels in hepatitis B.
 METHODS: A total of 157 serum samples were collected from outpatients with infection of HBV in Xiangya Hospital, Central South University. CMIA and TRIFA were used to analyze HBeAg quantitation and HBeAg/HBeAb qualitative detection, respectively.
 RESULTS: The linear regression equation for the two methods was Y=0.72779X-4.0551 (r=0.712, P<0.001). Compared with the CMIA, the sensitivity and specificity in detection of HBeAg by TRIFA were 89.89% and 100%, respectively, and the coincidence rate of HBeAg was 94.27% by two assays. Similarly, the sensitivity and specificity in detection of HBeAb by TRIFA were 100% and 95.45%, respectively. The coincidence rate was 97.45% by two assays.
 CONCLUSION TRIFA has similar accuracy, sensitivity, and specificity with CMIA in quantitative detection of HBeAg, and their coincidence rate in detection of HBeAg/HBeAb is high.
