Objective:To make a preliminary application of the assessment system for cancer pain management and find insuffi-ciency in the clinical practice of cancer pain diagnosis and treatment. Methods:Data from 41 doctor questionnaires, 43 nurse question-naires, 50 patient questionnaires, and 12 ward questionnaires from the tumor departments of 3 hospitals were analyzed, and the insuffi-ciency in cancer pain management was determined. The wards in the tumor and non-tumor departments related to oncology were as-sessed using rank test, and differences between the 2 wards were investigated. Results:The average scores of doctor, nurse, and wards were 85.41±5.93, 88.46±5.09 and 83.75±3.11, respectively, whereas patient score was 68.67±7.14. To further analyze the patient subsys-tem by converting into a hundred-mark system, the effectiveness and safety scores for the pain management was 81.69±7.71. However, patients' opinion score on pain treatment was only 55.78±11.37. The score of tumor departments was 82.22±2.03, whereas related non-tumor departments had a score of 39.27 ± 3.58. Wilcoxon W value was at 120.0 with P<0.01 after rank test. Conclusion:Education on patients' opinion on cancer pain management should be promoted in the tumor wards, and continuous education on cancer pain diagno-sis and treatment is needed in the non-tumor departments relative to oncology.

OBJECTIVETo investigate the effect of Xianxiong decoction on the mice with acute lung injury induced by lipopolysaccharide.

METHODEighty female ICR mice were randomly divided into 8 groups: model group, Xianxiong decoction group, Daxianxiong decoction group, Xianxiong decoction group without Kansui Radix group, Xianxiong decoction group without Glycyrrhizae Radix et Rhizoma group, Glycyrrhizae Radix et Rhizoma and Kansui Radix group, normal group and control group. Animals of each group, except normal group, were undertaken intraperitoneal injection and intranasal inhalation of lipopolysaccharide (LPS) on day 1, 2, 3 to establish acute lung injury (ALI) model. 30 min after modeling, 0.2 mL corresponding drugs were administrated to each mice, dexam ethasone and normal saline were given to the mice of control group and normal group respectively. White blood cell in blood, neutrophil percentage of blood and bronchoalveolar lavage fluid (BALF) supernatant, the ratio of wet and dry lung tissue ( W/D), histopathological changes of lung tissue were estimated. Sixty ICR mice were randomly divided into normal, model, control, high, middle and low dose Xianxiong decoction groups and were modeled in the same way. ELISA was applied to detect the level of NF-kappaB, TNF-alpha and IL-6 in BALF, PCR for NF-kappaB and TNF-alpha mRNA in lung tissue, and Western blot for NF-kappaB and TNF-alpha. Half of 20 ICR mice were administrated with Xianxiong decoction of its maximum tolerant normal saline.

RESULTCompared with model group, the number of WBC in blood of Xianxiong decoction group mice decreased (P < 0.01), percentage of neutrophils in both blood and BALF decreased as well (P < 0.01, P < 0.05); it also significantly reduced the ratio of W/D (P < 0.01); and found the alveolar wall, the number of inflammatory cells infiltrating improved, compared with model group. Xianxiong decoction reduced the level of NF-kappaB, TNF-alpha and IL-6 in BALF (P < 0.01, P < 0.01, P < 0.05); its high and low dose groups only found TNF-alpha level declined. Five mice died 24 h after administration of Xianxiong decoction which indicated its toxicity when other influential factors were considered.

CONCLUSIONXianxiong decoction is effective on the ALI mice induced by LPS, but it is of toxicity at 3 g x mL(-1).

Aim To investigate the changes of serum metabolism after the treatment of DOA and DOO on myocardial ischemia reperfusion ( MI/R ) injury in rats, and to explore the pathogenesis of MI/R injury and drug action mechanism. Method The serum samples of Sham group, Model group, DOA group and DOO group of rats were acquired, gas phase time of flight mass spectrometry ( GC-TOF-MS) was applied to analyze the metabolic profiles of the samples. After da-ta preprocessing, they were processed into SIMCA 14. 1 software for multivariate statistical analysis. Results By principal components analysis ( PCA ) , partial least squares analysis ( PLS-DA) and orthogonal partial least squares analysis ( OPLS-DA ) , the Model group and Sham group were obviously separated, the drug in-tervention group and Model group were separated and close to Sham group. The therapeutic effect of DOO and DOA on MI/R injury in rats was proved. The ex-perimental results identified 13 endogenous biomark-ers, which were related to the glucose metabolism,lipid metabolism and amino acid metabolism pathway. Con-clusion DOA and DOO may protect the MI/R injured rats by regulating the glucose metabolism, lipid metab-olism and amino acid metabolism pathway.

The purpose of this study was to synthesize and evaluate the necrosis target of MRI contrast agent based on rhein.The novel ligand 10-{ [6-(1,8-dihydroxyanthraquinone-3-carboxamido) hexyl] amino} acetyl-1,4,7,10-tetraazacyclododecan-1,4,7-triacetic acid (DO3A-rhein) was synthesized by two-step acylation and two-step deprotection.The paramagnetic contrast agent gadolinium 10-{ [6-(1,8-dihydroxyanthraquinone-3-carboxamido) hexyl] amino} acetyl-1,4,7,10-tetraazacyclododecan-1,4,7-triacetate (Gd-DO3A-rhein) was obtained by coordination of Gd3+ with the synthesized ligand.Its necrosis affinity was evaluated by liver infarction and muscular necrosis on rat models.The MRI was performed before administration of Gd-DO3A-rhein and during 0 h to 12 h after administration of Gd-DO3A-rhein (0.1 mmol/kg),respectively,and Gd-DOTA was used as control.After MRI scanning,rats were sacrificed and necrotic tissues were stained using triphenyltetrazolium chloride (TTC) and hematoxylin-eosin (HE).MRI images of liver infarction and muscular necrosis on rat models showed significantly enhanced signal intensity compared with normal tissues.The contrast ratios of necrotic liver/normal liver were 1.61 ±0.14 and 2.36 ±0.20 at 3 h and 12 h postinjection of Gd-DO3A-rhein (0.1 mmol/kg) respectively,demonstrating a significant difference compared with pre-administration of Gd-DO3A-rhein (1.16 ±0.10;P ＜ 0.05).The same results were obtained from necrotic muscles.These findings suggested that Gd-DO3A-rhein possessed the necrosis target and imaging capability of necrotic tissues.

Objective To analyze the genetic characteristics and the evolution of the influenza A (H3N2) virus strains circulating in Jiangsu province between 2013 and 2014.Methods This study analyzed thirty-one representative strains of influenza A (H3N2) virus, which were isolated in different regions of Jiangsu province and during different time periods from 2013 to 2014.Results Genetic distances in nucleic acid and amino acid between a strain used for vaccine production (A/Texas/50/2012) and the 31 strains were 0.010 5 and 0.012 4.Similarities between them in nucleic acid and amino acid sequences were 97.9%-99.6% and 97.2%-99.3%.Phylogenetic analysis showed that the hemagglutinin (HA) genes of the 31 strains were divided into three different groups.Three strains isolated in 2013 and three strains isolated in 2014 belonged to Group 1 and Group 2, respectively, while the others belonged to Group 3.Three positive selection sites (237, 366 and 367) in HA protein were observed by REL model.Compared with the strain used for vaccine production, the 31 strains were characterized by amino acid substitutions (N128A/T and P198S/A) in HA protein and all of the mutations located in B-cell epitopes.The total number of mutation sites reached 24.Compared with the A/Texas/50/2012 strain, seven strains presented the glycosylation site 126NWT, and three strains showed disappeared glycosylation sites of 45NSS and 144NNS.Evaluation of vaccine efficacy for A(H3N2) virus strains showed that the vaccine efficacy was not very well.Conclusion The HA gene of A(H3N2) virus had undergone a greater variation and the vaccine efficacy was not very well in Jiangsu province during 2013 to 2014, which made the influenza A(H3N2) virus become the circulating strain.

Objective To investigate the effects on IL-6 and PGE2 expression in wear-particles-induced osteoblast cells by blocking calcium phosphatase (Cn)/ activated T nuclear factor (NFAT) pathway. Methods Fetal Sprague-Dawley rats were used in this study. Osteoblast were prepared from the calvariae of rats . Osteoblast cells were incubated in four group according to different supplementation:(1) neither Ti particles nor 11R-VIVIT (Control group), (2) only Ti particles (Ti group), (3) both Ti particles and 11R-VIVIT (Ti/VIVIT group), and (4) only 11R-VIVIT (VIVIT group). Cells were incubated for 96 hours and the expression of NFATc1 protein was detected by western blot. The expression of IL-6 and PGE2 in liquid supernatant of osteoblast were detected at 6, 24 and 96 hours by ELISA. Results The expression of NFATc1 in the Ti group was higher than that in the Control group (P < 0.01), but in Ti/VIVIT group that was significantly lower than in the titanium particle group (P < 0.01). The IL-6 and PGE2 expression in the supernatant of the Ti group were significantly increased than those in the control group (P < 0.05). The IL-6 and PGE2 in the Ti/VIVIT group were significantly lower than that in the Ti group (P < 0.05). Conclusions 11R-VIVIT peptide specific blockade of Cn/NFAT signaling pathway significantly inhibited IL-6 and PGE2 of osteoblast cells induced by titanium particles.

Objective To observe the relationship between serum gamma-glutamyltransferase (GGT) and the risk factors of metabolic syndrome (MS). Methods Between April and August 2010, a total of 4110 persons from the out-patient Department of Tianjin First CentralHospital, were divided into two groups, the less than and the older than 65-year-old groups. Items as body mass index (BMI), blood pressure, FPG, serum total cholesterol(TC) ,triglyceride(TG) ,alanine transaminase (ALT) , aspartate aminotransferase (AST) , GGT, serum high-density lipoprotein level (HDL-C) , serum low-density lipoprotein level (LDL-C) and uric acid(UA) were tested and data was analyzed by SPSS. All subjects were divided into normaland abnormal groups, according to the GGT level. Results 14.6 percent of thesubjects in the younger groups and 24.3 percent in the older groups were diagnosed as MS. Significant differences were noticed among MS groups and normal groups, regarding items as BMI, dystolic, ALT, GGT, HDL-C, FPG, and UA(F<0.05). There were significant differences between GGT normal group and abnormal group (F<0.05). The GGT levels were significant positively related to the levels of BMI, dystolic, TC, TG, FPG and UA with Rs as 0.212, 0.226, 0.362,0.200,0.120 and 0.213 (P<0.01), while negatively related to the HDL-C level (r=-0.23, P<0.001). Data from the regression analysis demonstrated thatdystolic, TG, FPG and UA were predictors for GGT (β =0.170, 0.293, 0.107, 0.094, P<0.05). Conclusion GGT levels were significantly related to the risk factors of metabolic syndrome.

Background Hypertension is a multigenetic inheritable disease.Gene therapy with long-term effects and less side effects by regulating gene expression has been shown to be a potential and exciting prospect. Objective To investigate the effects of RNA interference(RNAi)targeting angiotensin-converting enzyme(ACE)on the blood pressure and ACE expression in kidney of spontaneously hypertensive rats(SHR).Methods SHR were randomly to receive placebo(n=12)or control adenovirus Ad5-EGFP)or a single injection of recombinant adenovi- ral vectors,Ad5-EGFP-ACE-shRNA(n=12,iv).Normotensive Wistar-Kyoto rats(WKY)were served as normal control group.SBP was measured before and after the intervention.Aorta,lung,myocardium and kidney were studied using fluorescence microscope to identify the sites of Ad5-EGFP-ACE-shRNA.Expressions of ACE mRNA and protein in kidney were evaluated by RT-PCR and Western blot.Results SBP of the treat group was effectively reduced by 19.0?3.2 mmHg at the 3rd day,and 22.1?3.3 mmHg at the 13th day of the experiment.The anti- hypertensive effect significant remained at least for 14 days.On the contrary,increase in BP was shown in placebo and the adenovirus control group.Compared with placebo or adenovirus control rats,ACE mRNA expression level in kidney of the treated rats was lower by 61.1% and 62.3% respectively,with ACE protein expression level lower- ing by 56.2% and 53.30% as well(ail P0.05). Conclusion RNA interference targeting ACE gene inhibits the expressions of ACE mRNA and protein.A single dose injection resulted in a prolonged decrease in BP.The evidence of strong antihypertensive effect by genetic therapy justifies efforts for further investigation.
