Object To investigate the structure, physicochemical properties and anticancer activity of three kind of glycyrrhizic acid aniline platinum complex compounds. Methods Using the FT IR methods, elementary analysis and X ray diffraction, the physicochemical properties of the tested drugs were determined; by means of MTT test the inhibitory effects of the drugs on human tumor cell growth were examined, with hematopoietic cell K 562 , melanoma cell LiBr and liver cancer cell 7721 as the model of anticancer activity. Results Experimental values of elemental analysis of three complex compounds tally with the theoretically calculative values. The infrared spectroscopy showed that the functional group location agreed with the structure. The X ray diffraction exhibited that this type of the compounds was monoclinic system. Conclusion The experimental results show that the anticancer activity of the test complex compounds is related to their concentration and ligands. Magnetic field treatment has significant influence on anticancer activity of this type of compounds.

Objective To explore the relationship between the levels of inflammatory factors and carotid intima-media thickness (IMT) in patients with type 2 diabetes mellitus (T2DM).Methods Fifty patients with T2DM were recruited and divided into T2DM with insulin resistance(IR) group(26 patients) and T2DM without insulin resistance (NIR) group (24 patients) according to insulin resistance index (HOMA-IR).Twenty-four healthy individuals conducting physical examination were recruited as the healthy control group.All participants underwent carotid ultrasound IMT to assess carotid intima-media thickness.The level of fasting plasma glucose (FPG),fasting insulin (FINS),blood lipids,high sensitivity C reactive protein (hs-CRP) and tumor necrosis factor-α(TNF-α) were measured.Homeostasis model assessment (HOMA)index was used for quantitative analysis of HOMA-IR.Results The levels of HOMA-IR,hs-CRP,TNF-α and IMT in control group,NIR group and IR group increased gradually and were significantly different(HOMA-IR:(1.74 ±0.49) vs.(2.24 ±0.41) vs.(4.89 ±0.84) ;F =190.228,P ＜0.01) ;hs-CRP(mg/L):(1.75 ±0.83) vs.(3.08 ± 1.04) vs.(5.89 ± 1.17) ;F =106.523,P ＜ 0.01) ;TNF-α (ng/L):(15.25 ± 7.64) vs.(23.38 ± 8.82) vs.(47.42 ± 9.97) ;F =89.210,P＜0.01) ;IMT(mm):(0.69 ±0.31) vs.(1.07±0.32) vs.(1.49±0.43);F=30.942,P＜0.01).Correlation analysis showed that the level of hs-CRP was positively correlated with the levels of HOMA-IR and IMT (r =0.453 and 0.395 respectively,P ＜ 0.05) ;The level of TNF-α was positively correlated with the levels of HOMA-IR and IMT (r =0.428 and 0.376 respectively,P ＜ 0.05) ; The level of HOMA-IR was positively correlated with the level of IMT (r =0.403,P ＜ 0.05).Conclusion Inflammatory activity is found in patients with T2DM,which is significantly correlated with insulin resistance.Inflammatory factors and insulin resistance play an important role in the occurrence and development of carotid atherosclerosis in patients with T2DM.

Medicinal properties are specific attributes of traditional Chinese medicines(TCM). The medicinal property theory is an important principle for the compatibility of traditional Chinese medicines. In this paper, medicinal properties, flavors and meridian tropism were combined to represent TCM medicinal properties; and multiple medicinal properties were further combined into medicinal property combination modes. TCMs and medicinal property combination modes were divided according to their efficacies, which were regarded as the concept of inductive logic programming and finally got medicinal property combination and compatibility rules with different efficacies. These medicinal property combination and compatibility rules were used to form the theoretical model through the entity grammar system, realize the automatic reasoning process from the medicinal property combination and compatibility to the efficacies, verify the reasoning result and analyze their rationality and limitations, in order to provide new ideas for revealing the relations between the TCM compatibility rules and efficacies.

ObjectiveTo explore the difference in quality of life in patients with gastrointestinal cancer between those who knew cancer diagnosis and those who did not.Methods 130 patients with recently diagnosed gastrointestinal cancer in 4 general hospitals in Tangshan were interviewed. Patients were categorized into two groups:one group was those who knew their diagnosis(n=62) and the other group was those who did not ( n =68).The Chinese version of European Organization for Research and Treatment (EORTC) quality of life (QOL)questionnaire (QLQ-C30) was used.ResultsThe comparison of quality of life between patients who knew their diagnosis and those who did not indicated that the score of global quality of life and other functional scales including physical,emotional,role and cognitive functioning did not show significant difference(P ＞ 0.05 ).Compared with those who did not know cancer diagnosis,patients who were aware of diagnosis showed a significant lower degree of social functioning ( (45.8 ± 24.2 ) vs ( 73.0 ± 16.2 ) ),a significant higher degree of fatigue ( ( 55.8 ±26.2) vs (41.8 ±10.2) ) and financial difficulties ((38.2 ±35.1) vs (12.00 ±10.0) ) (P＜0.01).In multiple regression analysis,physical functioning and symptom of fatigue had statistically significant differences (P＜ 0.05 ).ConclusionThe knowledge of cancer diagnosis does not contribute to the quality of life in patients with gastrointestinal cancer.

Objective To summarize the experience of general anesthesia management in pregnant women with pulmonary hypertension who had to undergo cesarean section. Methods Clinical data, anesthesia methods and outcome of 6 pregnant women with pulmonary hypertension were analyzed. Among them, 1 case of patent ductus arteriosus had to undergo cesarean section twice, because the interval time of twice cesarean section was longer (2 years), and the number of pregnant women was counted to 7 cases. Results Seven patients had to undergo cesarean section with general anesthesia, and all the pregnant women′s hemodynamic were stable during the operation. After operation, 1 pregnant woman discharged from hospital against the doctor′s advices because of massive brain infarction, and the others were all rehabilitated. Seven newborns status:preterm in 3 cases, cardiopulmonary resuscitation in 2 cases, the Apgar score of the others newborns was 9-10 scores. Conclusions Pregnant women with pulmonary hypertension have high peri-operative risk, especially those who undergo general anesthesia. To improve the survival rate, anesthetist should reinforce the perioperative care, maintain oxygen supply, reduce the stress response, maintain the preload and blood pressure, and avoid the increasing of pulmonary pressure.

Objective To observe contents and effect of total flavonoids of acanthopanax senticosus extract on erythrocyte membrane fluidity.Methods The contents of total flavonoids of acanthopanax sentieosus were deter- mined by spectrophotometry,and erythrocyte membrane fluidity and microviscosity were measured by fluorescence polarization technique.Results The total flavonoids contents of acanthopanax senticosus extract and injection were alike.Both of them increased erythrocyte membrane fluidity and lowered microviscosity,and the effect of acan- thopanax senticosus injection was more significant.Conclusion Total flavonoids of acanthopanax senticosus can in- crease erythrocyte membrane fluidity,so that blood viscosity is lowered and hemorheology factors are improved.

Objective: Cardiac resynchronization therapy defibrillator (CRT-D) increases ventricular transmural dispersion of repolarization (TDR). Our work evaluated the relationship between QTc interval of TDR indicators, TpTe, TpTe/QTc ratio and rapid ventricular arrhythmia in patients with CRT-D. Methods: A total of 160 consecutive patients who received CRT-D implantation in our hospital from 2011-01 to 2013-03 were studied. The immediate post operative ECG was collected to analyze lead V5 QTc interval, TpTe and TpTe/QTc ratio for assessing its TDR. The patients were divided into 2 groups: Treatment group, the patients with ventricular tachycardia or ventricular ifbrillation received CRT-D,n=30 (18.7%) and Non-treatments group,n=130 (81.3%). All patients were followed-up for (20 ± 10) months and the rapid ventricular arrhythmia was recorded by CRT-D devices. Results: The patients in Treatment group had increased TpTe/QTc (0.24 ± 0.05) vs (0.20 ± 0.04, and TpTe (119 ± 30) ms vs (95 ± 20) ms, bothP<0.001. The QTc interval was similar between 2 groups (480 ± 60) ms vs (470 ± 70) ms,P=0.6 and QTc interval was not related to the risk of CRT-D requirement. The sensitivity and speciifcity for TpTe/QTc ≥ 0.25 predicting the risk of ventricular arrhythmia in CRT-D patients were at 47% and 91%, while TpTe ≥ 120 ms were at 40% and 95%respectively. The post CRT-D surviving curve analysis indicated that TpTe/QTc ratio and TpTe could predict the prognosis in relevant patients,P<0.001. Conclusion: The elevated TpTe and TpTe/QT ratio may increase the incidence of CRT-D requirement in patients with ventricular arrhythmia after resynchronization.

Objective To investigate the effect of songling xuemaikang(SL-xmk)pretreatment on the expression of matrix metalloproteinase-9(MMP-9)after focal cerebral ischemia-reperfusion in rats.Methods A total of 45 male Sprague-Dawley rats were randomly allocated into SL-xmk pretreatment,sham operation,and normal saline control group.Preventive gavage was per-formed for 8 weeks in rats using SL-xmk(937.50 mg/kg)suspension in the SLxmk pretreatment group(n = 15);the preventive gavage was performed in rats using the equal volume of normal saline in the sham operation(n = 15)and normal saline control(n = 15)groups.At the end of the pretreatment process,a model of middle cerebral artery occlusion(MCAO)in rats was induced by suture method for 2 hours and reperfusion for 24 hours.The effects of SL-xmk pretreatment on the neurologic deficit scores after transient MCAO,brain water content,and infarct volume in rats were observed.Immunohistochemical staining was used to detect the MMP-9 immunoreactive positive cells in ischemic brain tissue.Results The neurologjc deficit scores(1.21 ± 0.25 vs.2.37 ± 0.35,P = 0.000),the brain water content (76.24% ± 7.09% vs.88.78% ± 6.57%,P = 0.000),the percentage of infarct volume (22.62% ±2.17% vs.27.84% ±3.43%,P =0.000),and the numbers of MMP-9 positive cells(16.20 ± 2.17/mm vs.20.60 ± 2.71/mm,P = 0.000)were all significantly lower than those in the control group.Conclusions SL-xmk pretreatment may significantly inhibit the expression of MMP-9 in the brain tissue of focal cerebral ischemia-reperfusion rats and reduce brain water content and infarct volume.
