Objective: To compare the efifcacy between emergent and delayed stent implantation in patients with ST-elevation myocardial infarction (STEMI) after thrombus extraction.
Methods: A total of 82 STEMI patients who received thrombus extraction and intracoronary injection of tiroifban, sodium nitroprusside, nitroglycerin via thrombus extraction catheter and with recovered TIMI 3 lfow from 2012-11 to 2014-01 were retrospectively studied. The patients were randomized into 2 groups by SAS software: Emergent group, the patients received stent implantation immediately upon diagnosis and Delayed group, the patients were treated by anti-platelet and anticoagulant medication for 10-14 days, and then received stent implantation. n=41 in each group. The primary and secondary indicators were compared between 2 groups which including ST-segment resolution (STR), the occurrence rate of no-relfow/slow-relfow, myocardial blush grade (MBG) 3, parameters of stent, ventricular remodeling condition, the incidence of major adverse cardiac events (MACE).
Results: ①Delayed group had the post PCI STR at (68.2 ± 9.2)%, TIMI 3 grade at 97.5%, MBG 3 at 69.0%and corrected TIMI frame count (CTFC) at (19.5 ± 5.2), compared with Emergent group, P<0.05. The occurrence rate of no-relfow/slow-relfow in Delayed group and Emergent group were 2.5% and 31.0%, P<0.01. ②The parameters of stents in Delayed group and Emergent group were as the number at (1.21 ± 0.32) vs. (1.76 ± 0.76), the mean length at (28.3 ± 11.7) mm vs. (33.7 ± 12.9) mm, the mean diameter at (3.17 ± 0.76) mm vs. (2.82 ± 0.87) mm, all P<0.01. Delayed group had the higher dilating pressure than that in Emergent group, (18.5 ± 6.2) atm vs (13.6 ± 7.1) atm, P<0.01, and more patients in Delayed group receive high-pressure non-compliant balloon dilation 75% vs 23.8%, P<0.01. ③With 6 months of follow-up study, there were slightly declining trend for LVEF and LVSF in both groups than that at 1 week condition, P>0.05, while LVEDV and LVEDD increased than 1 week, P<0.05, the changes were more obvious in Emergent group, P<0.05. Delayed group had less MACE occurrence, P<0.05.
Conclusion: Delayed stent implantation in STEMI patients after thrombus extraction had reduced incidence of post PCI no-relfow/slow-relfow phenomenon, improved myocardial reperfusion and less MACE occurrence.

Methods:Twelve microsatellite markers located at chromosomes 3p,9p and 14q were selected to investigate microsatellite alterations(MSI and LOH)in 31 RCC specimens and their paired metastasis specimens by polymerase chain reaction- polyacrylamide gel elect rophoresis-ethylene dibromide(PCR-PAGE-EB)staining and sequencing.Results:The frequency of MSI could reached 61.3% and that of LOH could reach 54.8%.The highest frequency of MSI was at locus of D9S168(32.3%);the highest frequency of LOH was at locus of D3S1289(21.4%).No correlation was found between MSI or LOH and the patients' age,sex,pathology type and metastastis,except that MSI was correlated with TNM stage of RCC(P

Objective To explore the effect of cutaneous never anastomosis on sensory recovery in repairing wide spreadly soft tissue defects in dorsal hand with free anterolateral femoral flap. Methods The cases with wide spreadly soft tissue defects in dorsal hand repaired with free anterolateral femoral flap from January 2006 to December 2012 were divided into 2 groups. The control group including 15 consecutive patients from January 2006 to January 2009, whose sensation was reconstructed in routine way. Other 15 consecutive patients from Febnary 2009 to December 2012 were as research group, whose sensation was reconstructed with the suture of cutaneous nevers of anterolateral femoral flaps and forearm. All the patients were followed up for 12~24 months. Results All the free flaps survived in both groups. There were 4 cases good of sensory recovery in the control group, and it was 11 in the research group. No ulceration happened. Conclusion Cutaneous never anastomosis may result in satisfactory sensory function in the patients with wide spreadly soft tissue descts in dorsal hand repaired with free anterolateral femoral flap.

On account of the dense cuticles of the fresh stem and the light, hard and pliable texture of the dried stem, Dendrobii Caulis is difficult to dry or pulverize. So, it is very important to the ancient doctors that Dendrobii Caulis should be properly treated and applied to keep or evoke its medicinal effects. The current textual research results about the preliminary processing, processing and usage methods of Dendrobii Caulis showed that: (1) In history the clinical use of fresh or processed Dendrobii Caulis as teas and tinctures were very common. (2) Its roots and rhizomes would be removed before using. (3) Some ancillary approaches were applied to shorten drying times, such as rinsing with boiling mulberry-ash soup, washing or soaking with liquor, mixing with rice pulp and then basking, etc. (4) According to the ancients knowledge, the sufficient pulverization, by means of slicing, rasping, hitting or pestling techniques, was necessary for Dendrobii Caulis to take its effects. (5) The heat processing methods for Dendrobii Caulis included stir-baking, stir-frying, steaming, decocting and stewing techniques, usually with liquor as an auxiliary material. Among above mentioned, steaming by pretreating with liquor was most commonly used, and this scheme was colorfully drawn in Bu Yi Lei Gong Pao Zhi Bian Lan (Ming Dynasty, 1591 CE) ; moreover, decocting in advance or long-time simmering so as to prepare paste products were recommended in the Qing Dynasty. (6) Some different processing programs involving stir-baking with grit, air-tightly baking with ondol (Kangs), fumigating with sulfur, which appeared in modern times and brought attractive outward appearance of the drug, went against ancients original intentions of ensuring drug efficacy.

It is held by some of the researches that the "16 collaterals" is composed of the "15 collaterals" and "the major collateral of stomach". And it is included into the textbook that Xuli, the major collateral of stomach, is the pulsation point at the cardiac region. Xuli is often explained as the empty portion of the human body by many researches. Through analysis and summarization of the related theory of the major collateral of stomach, the above mentioned opinion is discussed. And the understanding on the major collateral of stomach is deepened. As a result, it is concluded that count the major collateral of stomach into the 16 collaterals together with the 15 collaterals is inadvisable. The real pulsation point at the cardiac region locates under the left breast. And the real meaning of Xuli is "extending in all directions".

Objective To investigate the clinical value of axillary ultrasound (AUS)in the identification of axillary nodal metastasis (ALNM).Methods Two hundred and eighty-two consecutive patients with stage Tis-T2 breast cancer were prospectively enrolled between December 2013 and September 2015.All the patients underwent AUS performed by two specified senior ultrasound doctors.Sonographic features of their axillary lymph nodes (longitudinal and transverse diameters,cortical and hilar thickness,blood flow form)were collected.These patients were divided into metastatic, suspicious and non-metastatic groups based on the ultrasound features by ultrasound doctors.The diagnostic accuracy of AUS was compared with results of pathology.Univariate and multivariate Logistic regression analyses were used to evaluate the relationship between sonographic features and ALNM.The area under the ROC curve was used to assess the accuracy of the multivariate Logistic regression model.Results The sensitivity,specificity,positive and negative predictive value and accuracy of AUS were respectively 85.6%,87.1%,86.4%,86.3%,and 86.3% in the metastatic and non-metastatic groups.The Kappa value was 0.727(P <0.001).The ALNM burden in the non-metastatic group was significantly lower than in the metastatic group (1.2 vs 6.9,P <0.001).The false-negative results were found only in 16 cases,fourteen of whom had only 1,and two had 2 and 3 ALNM,respectively.Univariate Logistic regression analysis showed that maximum cortical thickness was the most significant predictive factor of ALNM(the area under the ROC curve was 0.872).Multivariate Logistic regression analysis suggested that cortical thickness and the ratio of hilar thickness to cortical thickness were predictive factors of ALNM(P <0.05).The area under the ROC curve of the multivariate Logistic regression model was 0.879 and its sensitivity and specificity were 77.0% and 85.1%,respectively.Conclusion AUS is a valuable tool for detecting ALNM.Patients with false-negative results of AUS have a lower axillary metastatic burden.Maximum cortical thickness is the most significant predictive factor of ALNM.AUS may be a potential alternative method for sentinel lymph node biopsy as axillary lymph node staging in early-stage breast cancer patients.

Objective To explore the association of NH2-terminal pro-B-type natriuretic peptide ( NT-proBNP) with the risk of type 2 diabetes.Methods One hundred and twenty-six impaired glucose regulation( IGR) participants from Diabetic Identification Center of Tianjin Metabolic Diseases Hospital were included.NT-proBNP was measured in plasma samples collected from participants at baseline condition.Results At baseline, NT-proBNP was inversely associated with body mass index, waist circumference, fasting glucose, insulin and low-density lipoprotein-cholesterol( LDL-C) levels.During a follow-up of 2 years, 51 participants reported a new diagnosis of diabetes from OGTT.Baseline quartiles of NT-proBNP were inversely associated with diabetes risk, even after multivariable adjustment.Theadjustedrelativerisksfordiabeteswere1.0(reference),0.83(95%CI0.74-0.96),0.78(95%CI 0.68-0.90), 0.74 (95%CI 0.64-0.87) for the 1st, 2nd, 3rd, and 4th quartiles of baseline NT-proBNP, respectively ( P<0.01 ) .Conclus ion In IGRpopulation , lowlevels of NT-proBNP were associated with a significantly increased risk of type 2 diabetes.

AIM: To investigate the bio-effects of salusins on rat heart and cardiomyocytes. METHODS: The cardiac function was determined by multipurpose polygraph in isolated rat heart treated with various concentrations of salusin-? or salusin-?. [ 45Ca 2+] and [3H]-Leu incorporation were determined in cultured neonatal rat cardiomyocytes with ?-liquid scintillation counter. RESULTS: 10 -12-10 -7mol/L salusin-? and salusin-? had no effects on isolated rat cardiac function. However, salusin-? and salusin-? stimulated [ 45Ca 2+] uptake and [3H]-Leu incorporation. The [ 45Ca 2+] uptake induced by salusins were inhibited by nicardipine, and were synergistically increased by endothelin-1. The [3H]-Leu incorporation induced by salusin-? and salusin-? was inhibited by nicardipine, FK506 (a special inhibitor of carcineulin), PD 98059 (inhibitor of MAPK) and chelerthine (inhibitor of PKC). The effects of salusin-? on [ 45Ca 2+] uptake was stronger than those of salusin-?. But there were no statistical difference in [3H]-Leu incorporation between salusin-? and salusin-?. CONCLUSIONS: Salusin-? and salusin-? did not affect directly cardiac function in rat hearts. But salusins improved calcium uptake and protein synthesize in neonatal rat cardiomyocytes. Those effects of salusins were related with calcium channel, carcinuelin, MAPK and PKC signal pathways. Salusins may be the regulatory factors for myocardium growth and hypertrophy.
