Objective: To analyze the information of patients with acute myocardial infarction (AMI) in a single center during last 6 years, and to distinguish the clinical differences of patients between TakoSTubo cardiomyopathy (TTC) and ST-segment elevation myocardial infarction (STEMI). Methods: A total of 1042 consecutive patients with primarily diagnosed acute anterior ST-segment elevation (STEMI) admitted in our hospital from 2008-01 to 2014-04 were retrospectively enrolled. The relevant patients were studied in 2 groups:TTC group, the patients with coronary angiography (CAG) and the contrast study of left ventricle corrected TTC diagnosis, n=10, and STEMI group, the patients received CAG within 6 hours of on set with conifrmed left anterior descending singlevessel disease at the same period of time as TTC patients,n=32. The basic clinical characteristics, levels of blood lipids, MI related biomarkers, the incidence rate of pathological Q wave, QTc interval and negative T wave in 12-lead ECG were compared between 2 groups. Results: The percentage of corrected TTC diagnosis in patients with primarily diagnosed STEMI was 1.06%. The female gender in TTC group and STEMI group was 100% vs 9%,P<0.01, TTC group had more patients with stress history before on set than that in STEMI group (70% vs 22%,P=0.02), lower levels of MI related biomarkers as CK (486 ± 249) U/L vs (716 ± 132) U/L, CK-MB (13.5 ± 17.1) mg/L vs (47.5 ± 21.9) mg/L, cTnI (22.8 ± 16.3) ng/mL vs (56.4 ± 24.0) ng/mL, allP<0.01. The age of morbidity, the ratios of hypertension, diabetes mellitus and blood lipids were similar between 2 groups. The frequency of abnormal Q-wave in ECG was similar between 2 groups, while the QTc interval was different in TTC group and STEMI group (630 ± 117) ms vs (540 ± 62) ms,P=0.001, the negative T waves in ECG leads II, III, aVF, aVR and V6 were as (100.00% vs 3.13%), (60.00% vs 6.25%), (90.00% vs 3.13%), (100.00% vs 21.88%), (100.00% vs 46.88%), allP<0.05. Conclusion: TTC patients with the main presentation as ST-segment elevation are usually having emotional or physical stress before on set, with obviously prolonged QTc interval and more frequency of negative T waves in ECG.

Objective To study the mechanism of glutamine dipeptide on wound healing after operations on bums. Methods Totally, 30 burned patients were randomly divided into study group and control group (15 cases in each group). All patients received parental nutrition support after operation. Study group patients were supplemented with glutamine dipeptide at a dose of 0. 5 g · kg±1 · d±1. The plasma free hydroxyproline level was measured by a standard amino acid analyzer 1 day before operation and 7 days after operation and the wound healing time was recor± ded. Results The plasma free hydroxyproline levels of both groups were higher than the normal values before opera± tion but without significant difference [control group: (2. 24 ±0. 84) fig/ml, study group: (2. 32 ±0.92) μg/ml, normal value: (1.27 ±0.44) μg/ml]. On the post±operative 7 day, the plasma free hydroxyproline level of study group [ (4. 31 ±1. 05) μg/ml] was significantly higher than that of control group [ (3. 04± 1. 01) μ/ml] (P = 0.002). The wound healing time of study group [ (29. 7±5.3) d] was shorter than that of control group but with± out significant difference [ (33. 3 ±7.5) d, P = 0. 14 ]. Conclusion The intravenous supplementation of glutamine dipeptide may increase the plasma hydroxyproline level after operation and thus promote wound healing.

Eight compounds from six Chrysanthemum morifolium cv. 'Hangju' were determined and multivariate statistics, including principle component analysis (PCA) and partial least squares discriminate analysis (PLS-DA) were used to investigate the potential damaging effect of sulfr-fumigating process. Meanwhile, S, Mn, Fe, Cu, Pb were also detected by using ICP-MS and ICP-OES. In this study, dramatic chemical changes were found that the contents of flavonoid aglycones remarkably increased while those of glycosides and hydroxycinnamoylquinic acids were significantly reduced. The PCA score plots showed six samples were clearly classified into the non-fumigated and sulfur-fumigated types. And according to VIP > 1, the most important chemical markers were luteolin, apigenin and luteolin-7-O-glucoside which indicated that the extracted three components might have a marked effect on the discrimination among different group samples. And then, it was found that the residue of sulfur of SHJ were significantly higher than NHJ (P < 0.05). The established approach was applied to rapidly discriminate sulfur-fumigated HJ with combining the quantitative chemical analysis and multivariate statistical analysis, and then the result will provide some evidence to evaluat the quality of HJ and control its processing.

OBJECTIVETo compare the sonographic findings with pathological features of ovarian thecoma, and to analyze the relationship between them.
METHODSThe sonograms of 45 ovarian thecoma cases were reviewed retrospectively and categorized into three subtypes as sound attenuation pattern, homogeneous hypoechoic pattern and solid and cystic mixed pattern. The pathological findings were classified as theca cell-predominant, fibroblast-predominant and mixed thecoma according to the cellular composition of the tumors. Hyaline degeneration and luteinization of the tumors were recorded. The pathologic findings of each subtype based on sonography were compared.
RESULTSOf the 45 patients, there were 34 (75.6%) solid ovarian lesions, 15 (33.3%) of those showed a sound-attenuation pattern with an anterior hypoechoic zone and posterior acoustic attenuation in sonography, the other 19 (42.2%) cases had homogeneous hypoechoic pattern with no posterior acoustic attenuation, and the remaining 11 (24.4%) cases presented as a solid and cystic mixed pattern. There were no significant differences in pathological cellular composition among the three sonographic subtypes. Five solid tumors containing hyaline degeneration and one with luteinization were found to have posterior acoustic attenuation. The solid and cystic mixed thecomas showed cystic degeneration and hemorrhage.
CONCLUSIONSolid ovarian thecomas usually have typical sonographic features, which may be associated with degeneration but not with cellular composition within the tumor.

The methods to determine the total phenols, total saponins, and marker constituents salidroside, chlorogenic acid and 3, 4-dihydroxy-phenylethyl-β-D-glucopyranoside in the samples of Sargentodoxae Caulis were established to provide the evidence for the improvement and revision of the quality standard of the crude material recorded in the Chinese Pharmacopoeia (2015 Edition). The content of total phenols was determined by ultraviolet spectrophotometry, using gallic acid as a reference substance. The content of total saponins was determined by ultraviolet spectrophotometry, using 3-O-[β-D-xylopyranosyl-(1-2)-O-β-D-glucuronopyranosyl]-28-O-[β-D-glucopyranosyl] asiatic acid as a reference substance. The contents of salidroside, chlorogenic acid and 3,4-dihydroxy-phenylethyl-β-D-glucopyranoside were detected by HPLC. The linear ranges were 1.01-7.04 mg x L(-1) for total phenols, 37.7-201 μg for total saponins, 0.025 8-1.55 μg for salidroside, 0.076 2-5.44 μg for chlorogenic acid, and 0.064 9-3.47 μg for 3,4-dihydroxy-phenylethyl-βP-D-glucopyranoside, respectively. Their average recoveries were 99.12%, 99.11% 105.5%, 99.08%, and 101.6%, respectively. The contents of total phenols and total saponins were 3. 04% -11. 9% and 0. 87% -3. 63%. The contents of salidroside, chlorogenic acid and 3,4-dihydroxy-phenylethyl-β-D-glucopyranoside fluctuated from 0.018% to 0. 572%, from 0.041% to 1.75% and from 0.035% to 1.32%. The established methods were reproducible, and they could be used for the quality control of Sargentodoxae Caulis. The present investigation suggested that total phenols, salidroside, and chlorogenic acid should be recorded in the quality standard of Sargentodoxae Caulis and their contents should not be less than 6.8% for total phenols, 0.040% for salidroside, and 0.21% for chlorogenic acid.
