Objective To analyze the association of blood uric acid level with the severity of coronary artery stenotic changes, metabolic syndrome (MS), and its components. Methods A total of 343 individuals ( male 223,female 120) who underwent coronary angiography and had complete data on MS and serum uric acid were collected. The severity of coronary artery disease (CAD) was assessed by the coronary stenesis index (CSI). MS was diagnosed according to the Guideline on Prevention and Treatment of Blood Lipid Abnormality in Chinese Adults. Results (1)The mean uric acid level was significantly lower in women than in men [ ( 306.3±76.9 vs 358.9±85.2 ) μmol/L, P＜0.01 ]. The prevalence of MS and its components showed no difference between men and women. (2) The uric acid level in women with 3 components was higher than those with1( P＜0. 01 ) or 2 ( P＜0.05 ) components of metabolic disorders, but not in men. (3) Quartiles of concentration of uric acid were computed. Compared with those in the lowest quartile of uric acid, women in the highest quartile had higher CSI score [ 7.0 (2.5-12.0) vs 2. 0( 0.0-6.0), P= 0. 025 ]. Moreover, the uric acid level was higher in women with multivessel lesions than nonCAD patients [ (327.0±81.9 vs 284.9±78.6) μmol/L, P = 0.033 ]. However, no correlation was found between uric acid level and the severity of coronary artery lesion in men. (4) Logistic regression showed that age (β=0.042, P=0. 007) and dyslipidemia(β=0.836, P=0. 037 ) were the independent risk factors of CAD in men, and hypertension(β=1. 127, P=0.039) and dyslipidemia(β=0.901, P=0.009)in women. Conclusions In women with higher uric acid level, the clustering of metabolic abnormalities was increased, and the coronary artery lesion was more severe. High uric acid level might be a marker of CAD for women.

Objective To explore the role of clinical pharmacists in rational drug use through the pharmacy care of an elderly pneumonia patient with Chlamydia psittaci infection and drug-induced liver injury. Methods The clinical pharmacists participated in the treatment of one patient with Chlamydia psittaci pneumonia and drug-induced liver injury. Based on the results of second-generation gene sequencing, the characteristics of the pathogen were learned by literature search. The clinical pharmacists monitored the patient’s liver and kidney function, provided a new medication treatment plan to Doctors, and performed patient education during the treatment. Results The initial empirical anti-infective treatment with teicoplanin and imipenem-cilastatin was not effective. After the diagnosis of Chlamydia psittaci and Candida albicans infection, the combination of doxycycline with azithromycin and fluconazole was administered. Drug-induced liver injury was found with this treatment. The clinical pharmacist proposed to switch to doxycycline and clarithromycin with co-administration of magnesium isoglycyrrhizinate and polyene phosphatidylcholine to protect the liver. With this new regime, patient's liver function was improved and the infection was under control. Conclusion Individualized pharmaceutical cares provided by clinical pharmacists helped the safe, rational and effective use of medications.

Background and Objective:Nitric oxide (NO) is involved in many physiologic and pathologic processes.As an important biologic mediator, NO has been the focus of cancer study for its function in tumorigenesis. Tumor progression.and death.This study investigated the effect of NO donor sodium nitroprusside(SNP)on the growth and proliferation of gastric cancer cell line AGS.Methods:The growth inhibition of AGS cells was analyzed by MTT assay.The cell cycle was measured using flow cytometry.The changes of mRNA expression of proliferating cell nuclear antigen (PCNA) and caspase-3 were examined by reverse transcriptase polymerase chain reaction (RT-PCR), and the protein expressions of PCNA and caspase.3 were analyzed by Western blot. Results:Dose-dependent SNP inhibited cell growth and proliferation.When the AGS cells were treated with SNP at 100,500,1000,1500,and 2000 μmol/L for 24 h.the growth inhibition rates were(2.02±2.96)%,(10.82±2.21)%,(18.95±3.35)%,(26.88±2.54)%,and(42.57±1.27)%,respectively(P<0.05).SNP altered the cell cycle in AGS cells.Compared with the control group,treatment with SNP at 100,500,1000,1500,and 2000 μmol/L for 24 h reduced the number of cells in the S phase by 2.29%,7.8%,11.34%,20.49%, and 23.6%,respectively, and enhanced the number of cells in the G_1/G_0 phases by 3.33%,9.3%,13.46%,21.37%,and 24.73%,respectively(P<0.05).With the increasing concentration and action time of SNP,the expressions of PCNA mRNA and protein decreased.The expression of caspase.3 mRNA remained unchanged,but procaspase-3 was activated.Conclusions:NO not only inhibits cell growth and proliferation, but also induces apoptosis in gastric cancer cells, and such effects of NO showed significant dosedependent activity.

Objective To evaluate collateral flows using vessel encoded arterial spin labeling (VE-ASL) perfusion imaging. MethodsVE-ASL was achieved to assess the presence and function of collateral flow on patients with internal carotid artery (ICA) stenosis. The presence of the anterior and posterior collateral flow was demonstrated by flow patterns of the A1 segment and posterior communicating artery (PCoA).Distal function of collateral flow of stenotic hemisphere was categorized as adequate ( cerebral blood flow ≥10 ml · min-1·100 g-1 ) or deficient (cerebral blood flow < 10 ml · min-1· 100 g-1 ). The results were compared with magnetic resonance angiography (MRA) and intraarterial digital subtraction angiography (DSA) in crosstable by using Kappa values. The VE-ASL before and after ICA stent therapy were compared. ResultsThe Kappa values of the flow patterns of AI segment and PCoA between VE-ASL and MRA were 0. 746 and 0. 700. The Kappa value of the function of collaterals using VE-ASL and DSA was914. VE-ASL showed collateral flow via leptomeningeal anastomoses. VE-ASL changed significantly after ICA steat therapy. ConclusionVE-ASL reveals the presence and distal function of collateral flow, which helps to evaluate the efficacy of ICA steat therapy.

Objective To know the mental health of secondary nursing students in Xinjiang and provide evidence for the psychological intervention.Methods 309 secondary nursing students in one health school were investigated with the general questionnaire,SCL-90 and EPQ.Results Compulsive symptoms rate in SCL-90was highest,and accounted for 72.5％.Average score in SCL-90 was (2.08 ± 0.56),and higher than national norm ( 1.75 ± 0.67) (t =10.25,P ＜ 0.01 ).Every factor score of SCL-90 about the secondary nurses was higher than the national norm,and had statistical difference (P ＜ 0.01 ). The girls,scores of depression (2.13 ±0.73),anxiety (2.08 ±0.72) and terrorist ( 1.93 ±0.74) were higher than boys [( 1.60 ±0.33),( 1.66 ± 0.52),( 1.42 ± 0.37 ) ],and the difference was significant ( t =- 5.54,- 2.12,- 4.68 ; P ＜0.05).The Uygur secondary nursing students,scores of somatization,coercion,depression anxiety and psychosis were higher and they have statistical differences (P ＜ 0.05 ).There is a direct correlation between all dimensions of SCL-90 and nervousness and psychoticism of EPQ (P ＜ 0.05 ),and were negative correlation with dissimulation ( P ＜ 0.05 ).Conclusions The mental health status of Xinjiang secondary nursing students are bad,so these students need to be paid more attention to their mental health,especially female nursing students and minority nationality nursing students.

OBJECTIVETo study the targeted point and mechanism of the function of the blood-activating and stasis-removing Chinese drugs, Paeoniae Radix 801(PR801) in its cardiovascular protective effects and its specific binding with endothelin 1 (ET-1) as well as the dynamics of the two's interactive function by means of using affinity biosensors: IAsys Plus and quartz crystal microbalance (IAQCM).

METHODSET-1 was immobilized on the surfaces of IAQCM by using the new surface modification methods. The PR801 in the solution was detected by modified substrates and the specific binding between PR801 and ET-1 was studied.

RESULTSThe curves went up or down after adding PR801. There is specific binding between PR801 and ET-1. The bound mass were 0.458 ng/mm(2) and 133.54 ng/cm(2), respectively. There exists relatively good stability with these two methods.

CONCLUSIONThe affinity biosensors: IAQCM can be used to study the interaction mechanism between PR801 and ET-1, providing a new way to study the interaction mechanism of TCM. PR801 can bind ET-1 specifically in the experiments. Therefore, ET-1 is another target that PR801 can bind specifically besides thromboxane A(2).
