ABSTRACT
This study primarily concentrated on scientific problems of poor taste caused by unclear critical quality attributes of oral preparations manufactured by Chinese materia medica, successfully established an identification method for taste critical quality attribute and a taste improvement method combining electronic tongue with human senses, and determined the optimal taste formula, to improve patients' oral medication compliance. The study received ethical approval from the Review Committee of the Beijing University of Chinese Medicine. The results showed that the proportion of bitterness of Xiaoer Qingrening Granule was 61.8%, and its bitterness grade was 3.70, it was determined that bitterness is the critical quality attribute that caused the poor taste of Xiaoer Qingrening Granule. Additionally, the optimal taste formula per milliliter of Xiaoer Qingrening sugar-free intermediate was determined with allowable daily intake, solubility, and sweetness as the limiting conditions, which was 40 mg hydroxypropyl β-cyclodextrin, 180 mg trehalose, and 1.5 mg acesulfame potassium. Compared with the Xiaoer Qingrening Granule, the sensory evaluation score of the optimal taste formula was increased by 37.5 points. In conclusion, this study achieved the taste improvement of Xiaoer Qingrening Granule and formed a set of taste improvement strategies including the identification of taste critical quality attribute, the selection of the type and dosage of corrigent, and the optimization of taste formula, which provided a thought reference for the taste improvement of other oral preparations and a new perspective for quality control of intelligent manufacturing of traditional Chinese medicines.

ABSTRACT
Objective:To test the reliability and validity of Work-ability Support Scale (WSS) in stroke patients. Methods:WSS was translated into Chinese with the standard translation-retroversion. From December, 2018 to March, 2019, 193 middle-aged and young stroke patients from two community health service centers in Zhengzhou were conveniently selected, and investigated with Chinese WSS by two nurses. The data were analyzed with item analysis, content validity, exploratory factor analysis, internal consistency reliability and inter-rater reliability. Results:The content validity was 0.94 in WSS A and 0.90 in WSS B. Three factors were extracted from 16 items in WSS A, with cumulative variance contribution of 67.747%; while three factors were extracted from 12 items in WSS B, with cumulative variance contribution of 56.056%. Cronbach's α was 0.933 and 0.778 in WSS A and WSS B, respectively. The kappa coefficient was above 0.6 between two raters in every item, except items B8 and B10. Conclusion:Chinese WSS is satisfactory in validity and reliability for using in young and middle-aged stroke patients during their return to work.
ABSTRACT
Objective: A network model of ulcerative colitis-associated colon cancer (UCRCC) and NF-κB signaling pathway was established, in order to predict the key inflammatory targets of UCRCC and identify the effect of GQD and composition of index components on these targets. Methods: HPLC method was used, the mobile phase was acetonitrile-0.2% phosphoric acid aqueous solution, and the gradient elution was carried out. The 10 indicators were determined. The literature of databases such as Pubmed and ScienceDirect were searched, the terms of the upstream and downstream proteins of UCRCC disease and NF-κB pathway were examined. The Cytoscape software was used to predict the key inflammatory targets of UCRCC. The UCRCC model was established by AOM/DSS method, and the effect of GQD and composition of index components on key inflammatory targets were identified by immunohistochemistry and ELISA. Results: The contents of puerarin, daidzin, glycyrrhizin, jatrorrhizine, baicalin, palmatine, berberine, baicalein, glycyrrhizic acid and wogonin in GQD were 1.677, 0.154, 0.159, 0.045, 0.448, 0.035, 0.095, 0.013, 0.111 and 0.006 μg/g, respectively. The top eight inflammatory factors of the key protein in the interaction network were NF-κBp65, iNOS, COX-2, Bcl-2, TNF-α, IL-1β, ICAM-1 and VCAM-1. Compared with the model group, the high-, medium- and low-dose groups of GQD, the composition of index components group and the 5-ASA group were able to down-regulate the relative expression levels of NF-κBp65, iNOS, Bcl-2, COX-2 in colonic tissues of UCRCC mice (P < 0.01), and down-regulate the expression levels of TNF-α, IL-1β, ICAM-1, VCAM-1 in serum of UCRCC mice (P < 0.05, 0.01). Conclusion: GQD and composition of index components can improve the pathological condition of colon tissue in UCRCC mice, down-regulate the expression of inflammatory factors in colon tissue of UCRCC mice, and have a certain intervention effect on UCRCC, which laid the foundation for determining the quality marker (Q-marker) of GQD.
ABSTRACT
Objective: To observe the impact and difference of resection of left stellate ganglion (LSG) or right stellate ganglion (RSG) on rats with heart failure. Methods: Thirty male SD rats were divided into 3 groups (n=10 each) by random number table method: control group, LSG group, RSG group. All three groups underwent TAC surgery to establish a pressure-overloaded heart failure model. Then, LSG and RSG were bluntly separated and removed in rats assigned to the LSG group or RSG group by surgery, while rats in the control group underwent sham operation. The changes in blood pressure and heart rate before operation, 30 minutes and 10 weeks after operation were recorded; echocardiography was performed before operation and 10 weeks after operation to detect the thickness of the ventricular septum, left ventricle posterior wall diameter, left ventricular end diastolic diameter, left ventricular end diastolic volume, and calculate the left ventricular fractional shortening and left ventricular ejection fraction. HE staining and Masson staining were performed to observe the degree of myocardial hypertrophy and myocardial fibrosis, and to judge the ventricular remodeling. Results: The heart rates of the three groups of rats were (352.4±4.3), (320.3±4.0) and (297.9±5.9) beats/min, and the blood pressure was (142.8±2.3), (123.4±2.7) and (129.6±2.9) mmHg(1 mmHg=0.133 kPa) at thirty minutes after surgery; the heart rates of the three groups of rats were (352.9±4.0), (321.6±3.4) and (301±4.1) beats/min, and the blood pressure was (145.6±1.9), (124.8±1.7) and (130.4±4.4) mmHg at 10 weeks after surgery. The heart rate and blood pressure in the LSG group and RSG group at 30 min and 10 weeks after surgery were significantly lower than those in the control group; at 10 weeks after surgery, the heart rate in the RSG group was significantly lower than that in the LSG group (P both<0.001). After 10 weeks, rats in the control group developed severe left ventricular dilatation. Degree of left ventricular hypertrophy was significantly reduced in the LSG group and RSG group than in the control group, the thickness of the ventricular septum was (3.2±0.3), (2.5±0.1) and (2.5±0.1) mm; the left ventricular end-diastolic diameters were (7.5±0.3), (5.5±0.3) and (5.7±0.2) mm; the left ventricular end-diastolic volume was (9.5±0.3), (4.5±0.2) and (4.8±0.2) ml; the left ventricular fractional shortening was (21.6±1.3)%, (49.1±3.9)% and (47.4±1.5)%; and the left ventricular ejection fraction was (50.9±2.5)%, (81.9±2.1)% and (80.0±2.3)%, respectively in the control group, LSG group and RSG group. Compared with the control group, the left ventricular posterior wall diameter, left ventricular end-diastolic diameter and left ventricular end-diastolic volume were significantly lower and the left ventricular fractional shortening and left ventricular ejection fraction were significantly higher in the LSG group and RSG group (all P<0.001). 10 weeks after operation, the values of type Ⅰ collagen in the control group, LSG group, and RSG group were (0.354±0.013), (0.211±0.012) and (0.243±0.013), respectively. Ratio of type Ⅰ/Ⅲ collagen was (1.109±0.065), (0.737±0.055) and (0.839±0.075), respectively. Compared with the control group, the ratio of type Ⅰcollagen and ratio of type Ⅰ/Ⅲ collagen were significantly lower in the LSG group and RSG group (P<0.001). Conclusion: Both left and right stellate ganglion resection can similarly reduce ventricular remodeling caused by pressure overload and delay the progression of heart failure in tis TAC rat model.

ABSTRACT
This prospective study was designed to examine the combined influence of insulin resistance (IR) and inflammatory biomarker levels on type 2 diabetes mellitus (T2DM) among 1,903 Inner Mongolians. During follow-up, 205 (10.77%) participants developed T2DM, and the incidence of T2DM was higher among subjects with IR, elevated C-reactive protein (CRP), elevated sICAM-1, elevated sE-selectin, or the coexistences of IR with elevated CRP, elevated sICAM-1, elevated sE-selectin, and elevated angiotensin II (all P < 0.05) compared with patients without IR or any elevated biomarkers. In multivariate analysis, the odd ratios [OR, (95% confidence intervals)] for these conditions were 1.944 (1.405-2.691), 2.003 (1.449-2.767), 1.706 (1.232-2.362), 1.560 (1.123-2.165), 2.708 (1.809-4.054), 1.885 (1.155-3.078), 2.101 (1.340-3.295), and 2.260 (1.426-3.582), respectively. Our findings demonstrated that IR and elevated inflammatory biomarkers were associated with T2DM, and that the coexistence of IR and elevated inflammatory biomarkers increased the risk of T2DM.

<p><b>Background</b>Shensong Yangxin Capsule (SSYX), traditional Chinese medicine, has been used to treat arrhythmias, angina, cardiac remodeling, cardiac fibrosis, and so on, but its effect on cardiac energy metabolism is still not clear. The objective of this study was to investigate the effects of SSYX on myocardium energy metabolism in angiotensin (Ang) II-induced cardiac hypertrophy.</p><p><b>Methods</b>We used 2 μl (10 mol/L) AngII to treat neonatal rat cardiomyocytes (NRCMs) for 48 h. Myocardial α-actinin staining showed that the myocardial cell volume increased. Expression of the cardiac hypertrophic marker-brain natriuretic peptide (BNP) messenger RNA (mRNA) also increased by real-time polymerase chain reaction (PCR). Therefore, it can be assumed that the model of hypertrophic cardiomyocytes was successfully constructed. Then, NRCMs were treated with 1 μl of different concentrations of SSYX (0.25, 0.5, and 1.0 μg/ml) for another 24 h. To explore the time-depend effect of SSYX on energy metabolism, 0.5 μg/ml SSYX was added into cells for 0, 6, 12, 24, and 48 h. Mitochondria was assessed by MitoTracker staining and confocal microscopy. mRNA and protein expression of mitochondrial biogenesis-related genes - Peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α), energy balance key factor - adenosine monophosphate-activated protein kinase (AMPK), fatty acids oxidation factor - carnitine palmitoyltransferase-1 (CPT-1), and glucose oxidation factor - glucose transporter- 4 (GLUT-4) were measured by PCR and Western blotting analysis.</p><p><b>Results</b>With the increase in the concentration of SSYX (from 0.25 to 1.0 μg/ml), an increased mitochondrial density in AngII-induced cardiomyocytes was found compared to that of those treated with AngII only (0.25 μg/ml, 18.3300 ± 0.8895 vs. 24.4900 ± 0.9041, t = 10.240, P < 0.0001; 0.5 μg/ml, 18.3300 ± 0.8895 vs. 25.9800 ± 0.8187, t = 12.710, P < 0.0001; and 1.0 μg/ml, 18.3300 ± 0.8895 vs. 24.2900 ± 1.3120, t = 9.902, P < 0.0001; n = 5 per dosage group). SSYX also increased the mRNA and protein expression of PGC-1α (0.25 μg/ml, 0.8892 ± 0.0848 vs. 1.0970 ± 0.0994, t = 4.319, P = 0.0013; 0.5 μg/ml, 0.8892 ± 0.0848 vs. 1.2330 ± 0.0564, t = 7.150, P < 0.0001; and 1.0 μg/ml, 0.8892 ± 0.0848 vs. 1.1640 ± 0.0755, t = 5.720, P < 0.0001; n = 5 per dosage group), AMPK (0.25 μg/ml, 0.8872 ± 0.0779 vs. 1.1500 ± 0.0507, t = 7.239, P < 0.0001; 0.5 μg/ml, 0.8872 ± 0.0779 vs. 1.2280 ± 0.0623, t = 9.379, P < 0.0001; and 1.0 μg/ml, 0.8872 ± 0.0779 vs. 1.3020 ± 0.0450, t = 11.400, P < 0.0001; n = 5 per dosage group), CPT-1 (1.0 μg/ml, 0.7348 ± 0.0594 vs. 0.9880 ± 0.0851, t = 4.994, P = 0.0007, n = 5), and GLUT-4 (0.5 μg/ml, 1.5640 ± 0.0599 vs. 1.7720 ± 0.0660, t = 3.783, P = 0.0117; 1.0 μg/ml, 1.5640 ± 0.0599 vs. 2.0490 ± 0.1280, t = 8.808, P < 0.0001; n = 5 per dosage group). The effect became more obvious with the increasing concentration of SSYX. When 0.5 μg/ml SSYX was added into cells for 0, 6, 12, 24, and 48 h, the expression of AMPK (6 h, 14.6100 ± 0.6205 vs. 16.5200 ± 0.7450, t = 3.456, P = 0.0250; 12 h, 14.6100 ± 0.6205 vs. 18.3200 ± 0.9965, t = 6.720, P < 0.0001; 24 h, 14.6100 ± 0.6205 vs. 21.8800 ± 0.8208, t = 13.160, P < 0.0001; and 48 h, 14.6100 ± 0.6205 vs. 23.7400 ± 1.0970, t = 16.530, P < 0.0001; n = 5 per dosage group), PGC-1α (12 h, 11.4700 ± 0.7252 vs. 16.9000 ± 1.0150, t = 7.910, P < 0.0001; 24 h, 11.4700 ± 0.7252 vs. 20.8800 ± 1.2340, t = 13.710, P < 0.0001; and 48 h, 11.4700 ± 0.7252 vs. 22.0300 ± 1.4180, t = 15.390; n = 5 per dosage group), CPT-1 (24 h, 15.1600 ± 1.0960 vs. 18.5800 ± 0.9049, t = 6.048, P < 0.0001, n = 5), and GLUT-4 (6 h, 10.2100 ± 0.9485 vs. 12.9700 ± 0.8221, t = 4.763, P = 0.0012; 12 h, 10.2100 ± 0.9485 vs. 16.9100 ± 0.8481, t = 11.590, P < 0.0001; 24 h, 10.2100 ± 0.9485 vs. 19.0900 ± 0.9797, t = 15.360, P < 0.0001; and 48 h, 10.2100 ± 0.9485 vs. 14.1900 ± 0.9611, t = 6.877, P < 0.0001; n = 5 per dosage group) mRNA and protein increased gradually with the prolongation of drug action time.</p><p><b>Conclusions</b>SSYX could increase myocardial energy metabolism in AngII-induced cardiac hypertrophy.

ABSTRACT
Objective To analyze the image characteristics of chest schwannoma in coincidence 18FFDG SPECT studies,and to evaluate its prospective diagnostic function on chest schwannoma.Methods Four cases confirmed as schwannoma by surgery and pathology were enrolled in this retrospective study.Enhanced CT and coincidence 18F-FDG SPECT studies were performed before surgery.Imaging characteristics for the diagnosis of chest schwannoma were summarized.Results Tumors were totally removed by surgery.The histological diagnosis of schwannoma was confirmed by pathological,HE and immunohistological staining examination (positivity for the S-100 protein and vimentin),including 1 case of malignant schwannoma and 3 cases of benign.Four cases all showed high uptake of 18F-FDG.The uptake in malignant schwannoma was much higher than that in benign schwannoma.Benign schwannomas were noninvasive masses and mainly showed compression symptoms,with obvious lobulation and distinct borders.Malignant schwannoma was invasive masses.Conclusions 18 F-FDG coincidence SPECT is of limited value as a prospective diagnostic imaging technique for the identification of benign schwannoma from malignant schwannoma.But it could play an important role in the staging,restaging,and post-therapy follow-up of schwannoma.
ABSTRACT
Objective To evaluate the diagnostic value of dobutamine?stressed cardiac morphing ( CM) MPI ( CMMPI) for coronary artery disease ( CAD) in middle?aged patients. Methods A total of 97 middle?aged patients (52 males, 45 females, age 40-65 (52.98±7.74) years) from March 2011 to Febru?ary 2015 with chest distress, cardiopalmus and chest pain symptoms ( suspected CAD) were retrospectively studied. Informed consents were signed by patients before examination. All patients underwent one?day dobu?tamine?stressed/rest CMMPI and CAG within one month. The diagnostic value of CMMPI was assessed and compared with CAG. Results CMMPI revealed 42 abnormal cases and 9 normal cases in 51 cases with cor?onary artery stenosis by CAG. CMMPI found 11 abnormal cases and 35 normal cases in 46 cases with normal coronary artery by CAG. In comparison with CAG, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of CMMPI were 82.35%(42/51), 76.09%(35/46), 79.38%(77/97), 79.25%(42/53)and 79.55%(35/44) respectively. The side effect was slight and transient with an inci?dence of 82.47%(80/97). Conclusion The dobutamine?stressed CMMPI has an important value for the diagnosis of CAD and the assessment of myocardial damage in middle?aged patients.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the application of the expanding forming under the plate through cervical spatium intermusculare approach to treat multi-segmental myelopathic cervical spondylosis.</p><p><b>METHODS</b>From July 2005 to June 2013, 25 patients with multi-segmental myelopathic cervical spondylosis were treated by the expanding forming under the plate through cervical spatium intermusculare approach including 16 males and 9 females with an average age of 56.5 years old ranging from 35 to 78 years old. Among them, 10 cases were onset without causes slowly, 7 cases were onset without causes suddenly, 8 cases were onset after mild trauma or tired. JOA scoring, incidence of postoperative axial symptoms and imaging studies were used to evaluate the effect.</p><p><b>RESULTS</b>Twenty-five cases were followed up for 6 months to 7 years and 6 months with an average of 2 years and 9 months. There were no infection, cerebrospinal fluid leakage after the operation, and complications such as nerve damage were occurred. The operation time was 120 to 150 min, the bleeding was 300 to 500 ml. Imaging examination showed vertebral canal sagittal diameter increased, the vertebral canal increased significantly in the cross sectional area of the spinal cord, cervical curvature was straighten in 4 cases (2 cases of them became normal sequence). There were no more cases of cervical protruding and segmental instability increased. Postoperative walking ability enhanced, the finger activity of majority of patients improved on flexibility, grip strength, and accuracy of using chopsticks improved, numbness and chest waist band feeling had different degree of reduce, preoperative urine impairment were improved to varying degrees. Preoperative JOA scores were 3 to 13 points with an average of (8.86 ± 4.25) points; Postoperative 12 months' JOA scores were 7 to 17 points with an average of (13.76 ± 3.56) points, period was 60.19% in average, JOA score had statistically difference between before and after operation (P < 0.05). The result were excellent in 14 cases, good in 6 cases, and fair in 4 cases and poor in 1 case.</p><p><b>CONCLUSION</b>Application of the expanding forming under the plate through cervical spatium intermusculare approach to treat multi-segmental myelopathic cervical spondylosis, through muscular clearance, can retain complete cervical back muscle, maintain stability of cervical spine, and vertebral canal can get effective decompression at the same time.</p>

Objective To investigate the biodistribution and gamma imaging of 99Tcm-arginine-glutamate-threonine (RET) in nude mice bearing lung cancer xenografts and to explore its feasibility for human lung cancer imaging.Methods RET was labeled directly with 99Tcm.The binding efficiency of 99Tcm-RET with human NSCLC H1299 cells was measured.99Tcm-RET was injected via the tail vein in nude mice bearing H1299 xenografts.The mice(n=32) were sacrificed at different time points:15 min,30 min,1 h,2 h,4 h,8 h,24 h,and 48 h.Organs of interest were excised,weighted and counted by a gamma counter.The organ uptake was calculated as ％ID/g.The gamma imaging was performed on 3 mice at 0.5,1,2,4,4.5,5,6 h after intravenous injection of 4.81 MBq 99Tcm-RET.Results The radiolabeling yield of 99Tcm-RET was (93.15±2.02)％,and the binding efficiency of 99Tcm-RET with H1299 cells was (3.56±0.37)％.At 4 h after injection,the uptake of tumor,liver and spleen was (4.96±1.05) ％ID/g,(15.89±1.84) ％ID/g and (10.83±1.66) ％ID/g and the T/NT was 5.70±0.21 for the heart and 12.40±0.11 for the blood.The tumor in nude mice could be best visualized at 4.5-6.0 h.Conclusion 99Tcm-RET might have potential to serve as a lung cancer imaging agent.
ABSTRACT
<p><b>OBJECTIVE</b>With functional magnetic resonance imaging (fMRI), cerebral function imaging of acupuncture and sham acupuncture at Taichong (LR 3) in patients with essential hypertension (EH) was observed to analyze central mechanism of Taichong (LR 3) to treat EH.</p><p><b>METHODS</b>Eighteen EH patients were divided into a twisting acupuncture group (10 cases) and a sham acupuncture group (8 cases), which were treated with twisting manipulation and sham acu- puncture at right Taichong (LR 3), respectively. The treatments were both given with 30-second manipulation and 30- second interval for totally 5 min. During the acupuncture, fMRI was adopted to scan the cerebral function imaging of EH patients on resting state, and the acquired data were analyzed with SPM2 module in Matlab software.</p><p><b>RESULTS</b>Acupunc- ture at Taichong (LR 3) in EH patients mainly increased opposite-side oxygen consumption, which generally activated left anterior cingulated gyrus (BA 32), left inferior parietal lobule (BA 40), left inferior temporal gyrus (BA 19), left middle temporal gyrus (BA 37) and right anterior central gyrus (BA 6). The activated areas were related to motor, vision and cognition of emotion. Stimulation region of sham acupuncture mainly included right anterior cingulated gyrus (BA 24), left inferior parietal lobule (BA 40) and left inferior frontal gyrus (BA 7).</p><p><b>CONCLUSION</b>The central mechanism of Tai- chong (LR 3) on antihypertensive effect and symptom improvement is not in thalamus and medulla that are traditionally believed to control blood pressure. Taichong (LR 3) could activate anterior cingulated gyrus to regulate parasympathetic nerve and lower blood pressure, and through anterior cingulated gyrus, the connection with the surrounding areas is strengthened to improve the cognitive impairment caused by long-term hypertension.</p>
