Objective To observe the protective effect of the separate zinc gluconate oral and combined of Salvia injection on whole blood metal ion of calcium,magnesium,iron,copper and zinc concentration in noise-induced rats.Methods 50 female SD rats were randomly divided into a control group,a noise group,a zinc gluconate noise group (plus zinc group),a Salvia injection noise group (plus Salvia group) and a Zinc gluconate oral liquid and Salvia injection noise group (combined group),with10 rats in each group.Except the control group did not expose to noise,the rest groups were continuously exposed to high frequency steady noise for two weeks.Each group was compared for the concentration differences of whole blood metal ion of calcium,magnesium,iron,copper and zinc after the intervention of noise.Results ① In each group at the comparison of the calcium ion concentration: Calcium ion concentration of the control group(1.25± 0.16)mmol/L and the combination group(1.27 ± 0.10) mmol/L was significantly lower than the noise group (1.42 ± 0.18) mmol/L.The rest groups compared to each other were not statistically significant.②Magnesium ion concentration was highest in the noise group (1.53 ± 0.10)rmtmol/L),and lowest in the control group (130 ± 0.29) mmol/L,and the noise group was significantly higher than that of the control group.The mean of magnesium ion concentration in plus zinc group (1.42± 0.27) mmol/L,plus Salvia group (1.38± 0.15) mmol/L and combined group(l.37±0.11)mmol/L were lower than the noise group,but the difference was not significant (P＞0.05).③ The iron ion concentration of the noise group (5.47± 1.29)mmol/L was significantly lower than the other four groups (P＜0.05).The control group,plus zinc group,plus Salvia group,the combined group showed no significant differences.④ Whole blood copper ion concentration of the noise group (16.69 ± 4.18) μmol/L was significantly lower than the control group (21.53 ± 3.78) μmol/L and the combination group(19.53± 1.92)μmol/L with a statistical difference; compared with the control group,the concentration of copper ions in plus zinc group(16.19± 1.93)mμol/L was significantly lower (P＜0.05).⑤The whole blood zinc ion concentration in the noise group (50.83±7.99)μmol/L was significantly lower than the other groups,zinc ion concentration in the plus Salvia group (53.87±6.77)μmol/L was significantly lower than the control group (63.86± 8.83) μmol/L; the whole blood zinc ion concentration showed no difference between the plus zinc group (54.81 ± 5.90) μmol/L,plus Salvia group and combined group (59.21 ± 3.90) μmol/L.Conclusion Combined zinc gluconate oral solution and Salvia injection had protective effect on whole blood metal ion concentration affected by noise.The protection effect of zinc gluconate oral solution and Salvia injection combination was stronger than any individual.

Objective · To investigate antiemetic effect of aprepitant for moderately chemotherapy-induced nausea and vomiting in patients with gastrointestinal cancer. Methods · From 2014 July to 2015 August, 130 cases of gastrointestinal cancer patients were collected in Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine, who received moderate emetogenic risk of chemotherapy for at least four courses. One hundred and nine patients were treated with aprepitant, palonosetron and dexamethasone on day 1, and aprepitant and dexamethasone on day 2 and 3. Twenty-one patients only received aprepitant and dexamethasone on day 1 and dexamethasone on day 2 and 3 in the first course of chemotherapy. During subsequent courses of chemotherapy they received aprepitant and treated in the same way as 109 patients. MASCC antiemetic tool (MAT) was used to evaluate the intensity of nausea. The primary endpoint was complete response (CR, no emesis and use of no rescue antiemetics) during the overall study phase (0-120 h after chemotherapy) at the second course. The secondary endpoint was complete protection (CP, CR plus no significant nausea) during the overall, acute (0-24 h), and delayed (24-120 h) phases at the second course. Results · The CR rates were 90.0%, 94.6% and 90.8% of patients in the overall, acute and delayed phases, respectively. The corresponding CP rates were 83.8%, 87.8% and 84.6 %, respectively. The CR rate increased from 42.9% to 57.1% during acute phase and increased from 9.5% to 90.5% during delayed phase for 21 patients after treatment with aprepitant. The main adverse reactions include constipation, anorexia and hiccups. Conclusion · Aprepitant combined with palonosetron and dexamethasone can effectively prevent moderately chemotherapy-induced nausea and vomiting in patients with gastrointestinal cancer. Aprepitant therapy can effectively maintain antiemetic effect in patients with many chemotherapy courses.

ObjectiveThe purpose of this paper is to grade hypervascularized mass lesions in CE MR imaging of the breast by analyzing morphology and dynamic characteristics.MethodsCriteria for the evaluation of breast MR findings were used,including the analysis of shape,margin,internal enhancement characteristics,initialenhancementphase,anddelayedphaseenhancementpattern.Atotalof 188 hypervascularized mass lesions were analyzed,and scores were given from 1 to 10 points and then the mass was classified into one of five categories.Next,the score results and pathology results were used to calculate the ROC curve and to find out the optimal benign and malignant diagnosis points.According to these results,the lesions were classified as benign or malignant.The sensitivity and specificity of this classification system were also calculated.ResultsOut of the 188 hypervascularized mass lesions,91 lesions were confirmed to be malignant by pathologic diagnosis and 97 to be benign.The area under the ROC curve was 0.938 ± 0.016.This curve was used to calculate the optimal point of differentiation diagnosis,and it was found to be a score of 5.The 188 lesions were classified into grade Ⅱ of 24 lesions,grade Ⅲ of 72,grade Ⅳ of 54,and grade Ⅴ of 38.Sensitivity for the detection of malignancy using this classification system was 87.91％ and specificity was 87.62％.If the three cases with false negative results of ductal carcinoma in situ of grade Ⅲ were excluded,the specificity increased to 90.90％.Conclusion The classification based on a multifactorial analysis is very helpful in the objective interpretation of breast CE MRI.

Traditional Chinese medicine (TCM) has definitely clinical effect in treating hyperlipidemia, but the action mechanism still need to be explored. Based on consulting Chinese Pharmacopoeia (2010), all the lipid-lowering Chinese patent medicines were analyzed by associated rules data mining method to explore high frequency herb pairs. The top three couplet medicines with high support degree were Puerariae Lobatae Radix-Crataegi Fructus, Salviae Miltiorrhizae Radix et Rhizoma-Crataegi Fructus, and Polygoni Multiflori Radix-Crataegi Fructus. The 20 main ingredients were selected from the herb pairs and docked with 3 key hyperlipidemia targets, namely 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG-CoA reductase), peroxisome proliferator activated receptor-α (PPAR-α ) and niemann-pick C1 like 1 (NPC1L1) to further discuss the molecular mechanism of the high frequency herb pairs, by using the docking program, LibDock. To construct evaluation rules for the ingredients of herb pairs, the root-mean-square deviation (RMSD) value between computed and initial complexes was first calculated to validate the fitness of LibDock models. Then, the key residues were also confirmed by analyzing the interactions of those 3 proteins and corresponding marketed drugs. The docking results showed that hyperin, puerarin, salvianolic acid A and polydatin can interact with two targets, and the other five compounds may be potent for at least one of the three targets. In this study, the multi-target effect of high frequency herb pairs for lipid-lowering was discussed on the molecular level, which can help further researching new multi-target anti-hyperlipidemia drug.

Referring to the rules for agricultural seed testing (GB /T 3543-1995) issued by China, the test of sampling, seed purity, weight per 1 000 seeds, seed moisture, seed viability and germination rate had been studied for screening seed quality test methods of Pesudostellaria heterophylla. The seed quality from different collection areas was measured. The results showed that at least 6.5 g seeds should be sampled and passed through 10-mesh sieve for purity analysis. The weight of 1 000 seeds was determined by using the 500-seed method. The phenotypic observation and size measurement were used for authenticity testing. The seed moisture was determined under the higher temperature (130 ± 2) degrees C for 5 hours. The seeds were dipped into 0.2% TTC sustaining 1 hour at 40 degrees C, then the viability could be determined. The break dormancy seeds were cultured on sand at 10 degrees C. K cluster analysis was applied for the data analysis, the seed quality from different collection areas grading of P. Heterophylla was described as three grades. The seed quality of each grade should reach following requirements: for first grade seeds, germination rate ≥ 86%, 1 000-grain weight ≥ 2.59 g, purity ≥ 87%, moisture ≤ 13.1%; for second grade seeds, germination rate ≥ 70%, 1 000-grain weight ≥ 2.40 g, purity ≥ 77%, moisture ≤ 14.3%; for third grade seeds, germination rate ≥ 41%, 1 000-grain weight ≥ 2.29 g, purity ≥ 76%, moisture ≤ 15.8%. The seed testing methods for quality items of P. heterophylla had been initially established, as well as the primary P. heterophylla seed quality classification standard.
