Objective:To explore expression of plasma omentin -1 in patients with central obesity (CO) complicated essential hypertension (EH) and its clinical significance .Methods : Serum level of omentin - 1 was measured by enzyme linked immunosorbent assay in 57 CO patients without EH (pure CO group) and 67 CO complicated EH patients (CO + EH group) ,and 56 healthy subjects (normal control group) .Blood glucose ,blood lipid and biochemical indexes were compared and analyzed among three groups ,and Logistic multi - factor gradual regression analysis was used to perform risk factor analysis .Results : Serum omentin - 1 level in CO + EH group was significantly lower than those of pure CO group and normal control group [ (25.15 ± 3.95) ng/ml vs .(45.63 ± 9.66) ng/ml ,(53.12 ± 7.97) ng/ml , P < 0.05 or < 0.01] ,but there was no significant difference between pure CO and normal control group , P > 0.05 ;Logistic multi - factor gradual regression analysis indicated that age and homeostasis model - insulin resistance index (HOMA - IR ) were independent risk factors affecting EH occurrence in obese people (OR = 1.124 ,95% CI : 1.000 - 1.248 ,P = 0.049 ;OR = 3.446 ,95% CI : 1.087 - 5.607 ,P = 0.001) ,while serum omentin - 1 level was an independent protective factor (OR = 0.423 ,95% CI : 0.210 - 0.636 , P = 0.001) .Conclusion : Serum omentin - 1 level may possess certain guiding significance in early diagnosis ,prevention and treatment for patients with central obesity complicated essential hypertension .

Object To study the effect of puerarin on the expression of inflammatory factors and miR-155-3p in human umbilical vein endothelial cells ( HUVEC) induced by visfatin.Methods The HUVEC cell injury model was es-tablished with visfatin.Cell proliferation was measured by MTT assay.Cell apoptosis was detected by flow cytometry.The level of CRP and NF-κB was detected by ELISA, and the expression of miR-155-3p was detected by RT-PCR.The expres-sion of myeloid differentiation factor 88 ( MyD88) was identified by western blotting.Results Visfatin induced cell prolif-eration and inhibited apoptosis in HUVEC, meanwhile the expressions of both CRP and NF-κB were significantly increased, compared with that of the control group (P<0.01).Puerarin at moderate and high concentrations obviously reduced the HUVEC injury induced by visfatin, mainly through down-regulating the expression of CRP and NF-κB, as well as up-regu-lating the level of miR-155-3p in the HUVEC.MiR-155-3p mimic markedly decreased the level of MyD88, CRP and NF-κB in the HUVEC induced by visfatin (P<0.05).Conclusions Pueprarin obviously alleviates HUVEC injury induced by visfatin, probably related to down-regulating the level of MyD88, CRP, NF-κB, and up-regulating the expression of miR-155-3p in HUVEC.

Many medical journals have already digitalized their publishing procedure,but not achieved digital publishing yet.Utilizing digital technology,digital publishing can achieve the functions that paper media cannot,such as information storage,fast search,real-time publishing,individualized information and interaction with readers.These functions entail digitalization of medical journals,and involve a range of macro- and micro-modifications,including laws,industry policies,personnel training,and culture development.There is a long way to go for Chinese medical journals to enter the stage of digital publishing.

Objective To explore the efficacy and safety of dyclonine hydrochloride mucilage applied as a lubricant for orotracheal intubation. Methods A prospective study was conducted,144 patients with respiratory failure(RF)and clear consciousness admitted into Emergency Department of Xingtai People's Hospital in December 2010 to June 2013 for orotracheal intubation were randomly divided into experimental and control groups(each, 72 cases). Topical spray anesthesia onto the throat wall was applied for all the patients before orotracheal intubation. In the experimental group,the patients received 1%hydrochloric acid dyclonine mucilage as a lubricant,while in the control group,they received paraffin oil as a lubricant before the insertion of tracheal tube. The operating procedure of the insertion was in accord to the rules of orotracheal intubation in both groups. The changes of heart rate,systolic blood pressure,diastolic blood pressure,pulse oxygen saturation(SpO2),success rate of once tracheal intubation,incidence of choking cough,the time of tracheal intubation and dyclonine adverse reactions were observed. Results The heart rate,systolic and diastolic blood pressures were significantly higher and SpO2 was obviously lower after the intubation in both groups than those before the procedure,and the changes were more significant in the control group〔heart rate(bpm):135.2±9.9 vs. 98.1±8.1,systolic blood pressure(mmHg,1 mmHg=0.133 kPa):145.6±20.8 vs. 138.8±22.1,diastolic blood pressure(mmHg):96.1±17.6 vs. 82.9±22.8,SpO2:0.643±0.128 vs. 0.749±0.102, all P<0.05〕;the success rate of once tracheal intubation in experimental group was significantly higher than that in the control group〔98.6%(71 cases)vs. 84.7%(61 cases),P<0.01〕,the incidence of choking cough was obviously lower than that in the control group〔36.1%(26 cases)vs. 52.8%(38 cases),P<0.05〕,the time for insertion of tracheal tube in experimental group was also significantly shorter than that of control group(minutes:1.9±0.9 vs. 2.3±1.1,P<0.05). No drug adverse reactions occurred. Conclusion Compared with paraffin oil,dyclonine hydrochloride mucilage as a lubricant for tracheal intubation is a simpler and easier operation which has the advantages of having better anesthesia,effectively reducing the irritation of the throat wall,improving the success rate of intubation,being more tolerable by the patients,reducing the adverse reaction rate during insertion of tube and having no occurrence of drug adverse reactions,therefore dyclonine can be applied in tracheal intubation.

Objective To observe the parameters and effect of endocardial pacing by steel wire electrode cardiac puncture on heart with normal beat in living animal, and evaluate its safety.Methods After anaesthesia and thoracotomy in 6 living dogs with normal heart beat, the pericardia were excised. Steel wire electrodes with annular or hook tips were used respectively at right ventricular 4 corresponding spots to perform cardiac puncture endocardiac pacing (each dog experienced 8 times of puncture); the time from puncture to effective pacing, pacing parameter and puncture complication (time and quantity of bleeding) of each electrode at each spot were recorded. Finally, the two types of electrode completed 24 times of manipulation respectively; the data collected of the two types were compared. Results The cardiac pacing successful rates in the two groups were 100%; the time taken from the beginning of heart puncture to effective pacing in annular tip group was less than that in hook tip group, but the time difference between the two groups showed no statistical significance (s: 18.4±2.3 vs. 19.6±4.1,P > 0.05). The parameters of pacing in the annular tip group, such as operation time (s: 18.4±2.3 vs. 19.6±4.1), the threshold value of pacing (V: 2.1±0.2 vs. 2.2±0.8), the amplitude of R wave sensed (mV: 11.3±3.2 vs. 12.6±4.1) and the impedance of electrode (Ω: 674.2±89.7 vs. 668.5±101.3) were not significantly different compared with those in the hook tip group (allP > 0.05). Either after puncture or after the electrodes were taken out, the time of bleeding [after puncture (minutes): 4.4±2.3 vs. 4.5±3.1, after the electrodes taken out (minutes): 4.1±2.2 vs. 4.8±2.5] and the volume of bleeding [after puncture (mL): 2.8±2.4 vs. 3.2±3.5, after the electrodes taken out (mL): 3.3±1.7 vs. 3.5±2.6] were not significantly different between the two groups (allP > 0.05).Conclusions In living dogs with normal heart beat, the manipulation and function of endocardiac pacing by cardiac puncture with either steel wire annular or hook tip electrode are well and effective, and the performance is simple and safe without any serious myocardial injury and complication. Thus, it is helpful to quickly establish efficient endocardiac pacing in emergency cases.

Objective To test the effectiveness, reliability and acceptability of the European Organization for Research and Treatment of Cancer (EORTC) QLQ-STO22 scale in gastric cancer patients in China. Methods One hundred and twenty-eight cases were collected in the Affiliated Cancer Hospital of Xiangya School of Medicine of Central South University from September 2014 to April 2015. All the patients completed the EORTC QLQ-STO22 and EORTC QLQ-C30 scales and given the Zubrod-ECOG-WHO (ZPS) score. Karen Bach coefficient and Pearson correlation test were used for statistical analysis while using ZPS score to detect EORTC QLQ-STO22 in validity. After score was standardized, P<0.05 represented the difference had statistical significance. Results The Karen Bach coefficient was 0.607-0.830, confirming that the EORTC QLQ-STO22 scale had good reliability. A number of enhanced analysis showed that the scale had good convergent validity and divergent validity. In the same or similar dimension, EORTC QLQ-C30 and EORTC QLQ-STO22 scales had good correlation and the correlation scores were higher than 0.400. The patients were divided into four groups according to ZPS score, with ZPS score increase, the overall quality of life scores were decreasing and entries associated with symptoms were increasing, showing difference between different groups(P<0.05). Conclusion The EORTC QLQ-STO22 scale shows high reliability and validity that can be used for assessing the quality of life of patients with advanced gastric cancer in China.

Objective To study the effect of a Chinese medicine, Huanglian Jiedu Decoction ( HLJDD) , on ath-erosclerotic plaque, inflammatory factors and regulatory T cells in ApoE-/- mice. Methods High fat diet was given to ApoE-/- mice to establish an atherosclerosis model. 40 male ApoE-/- mice were randomly divided into five groups:model group, simvastatin group, low, moderate and high dose HLJDD groups (n =8). HLJDD was intragastrically administered in a dose of 3. 5, 7. 0, or 14. 0 g/( kg?bw) once dailg for 16 weeks. The dose of simvastatin was 5. 0 g/( kg?bw). An-other 8 male C57BL/6J mice were taken as control group. At the end of the 29-week experiment, all of the mice were sacri-ficed. The aortic plaques, level of blood lipids, inflammatory factors, Tregs number and the level of Foxp3 mRNA were de-tected and analyzed by ELISA, flow cytometry and RT-PCR, respectively. Results Compared with the control group, the aortic plaques were much larger in the model group, and the levels of TC, TG, LDL-C, IL-6, hs-CRP, and TNF-α were significantly higher than those in the control group (P<0. 01 for all). Meanwhile, the levels of HDL-C, IL-10, TGF-βand Foxp3 mRNA were much lower than those in the control group ( P<0. 01 for all) , and the Tregs numbers were less than that in the control group (P<0. 01). HLJDD regulated the blood lipids in ApoE-/ - mice and decreased the levels of IL-6, hs-CRP, andTNF-α, however increased the levels of IL-10, TGF-β and Foxp3 mRNA. At the same time, it in-creased Tregs number in the ApoE-/ - mice. Compared with the model group, the difference was statistically significancet (P<0. 01). Conclusions HLJDD can significantly alleviate the aortic plaque damages in ApoE-/ - mice. It may be re-lated to the up-regulation of Tregs, which can lead to decrease the expression of serum pro-inflammatory factors such like IL-10, hs-CRP and TNF-α.

Objective To investigate the effect of Shensong Yangxin capsule on cardiac remodelling of myocardial infarction mouse model and the possible molecular mechanisms. Methods Adult male C57BL/6J mice were divided into sham operation group(n=10), model control group(n=20)and Shensong Yangxin group(n=20)according to random number table. Left anterior descending branch of coronary artery was ligated to establish myocardic infarction model in the model control group and Shensong Yangxin group. From the 2nd day after the surgery, Shensong Yangxin ( 400 mg . kg-1 ) was intragastrically administered, and the death rate of the mice was observed.Four weeks after the surgery, echocardiography was used to measure the cardiac function;myocardiac infarction area was detected by pathological staining;the expression levels of cardiac remodelling markers and extracellular matrix proteins were detected by RT-PCR. The possible molecular mechanisms were screened by Western blotting. Results As compared with the model control group, Shensong Yangxin significantly reduced the mortality after myocardial infarction in mice(P<0.05), as well as the myocardial infarct size(P<0.05).The mRNA expression levels of cardiac remodelling markers ANP, BNP, and β-MHC and the extracellular matrix proteins(collagenⅠ, collagen Ⅲ, CTGF, TGFβ) decreased significantly in the Shensong Yangxin group as compared with the model control group. Western blotting showed that Shensong Yangxin significantly decreased activation of smad3, and reduced expression level of smad4. Conclusion Shensong Yangxin attenuates cardiac remodelling after myocardial infarction and the mechanism may be related with blockage of smad signaling pathway.
