The paper first analyzes the intrinsic need for cultural integration in hospital regrouping and sums up its content, including the integration of values, management ideas, institutional cultures and institutional frameworks. It then introduces some methods of cultural integration in hospital regrouping, such as running in on the basis of respecting human nature, resolving conflicts on the basis of being mutually tolerant, and merging completely on the basis of optimizing means of integration. The paper points out that success or failure of cultural integration in hospital regrouping depends on the thinking of the leaders. For this reason, it is imperative to enhance integration awareness and improve integration capability.

ObjectiveTo study the correlation of urinary iodine and thyroid function in elderly men in Harbin,and to provide the basis for formulation of health measures for the elderly.MethodsSeventy five cases of clinically healthy elderly men were enrolled for check-up of urinary iodine,thyroid function and B-ultrasound in Geriatric Ward the Forth Affiliated Hospital of Harbin Medical University in 2010.The subjects of investigation were divided into iodine appropriate and iodine sufficient groups and thyroid function parameters and B-ultrasound results were compared.ResultsThe average age of the 75 cases of healthy elderly men was (79.07 ± 4.78) years old and the median of urinary iodine was 198.4 μg/L.There were 62.67％ (47/75) elderly males whose iodine nutritional status was appropriate,but there were still some individuals(6.67％,5/75) in the iodine excess state.The level of TSH of the iodine appropriate group [(1.91 ± 0.82)mU/L] was lower than that iodine sufficient group [(4.98 ±0.60)mU/L,t =12.58,P ＜ 0.05],while the level of FT3 of the iodine appropriate group[(4.71 ± 0.56)pmol/L]was higher than that iodine sufficient group[(3.31 ± 0.43)pmol/L,t =12.18,P ＜ 0.05].But the difference of FT4between the two groups [(14.91 ± 3.12),(14.06 ± 2.79)pmol/L] was not statistically significant (t =1.40,P ＞0.05].The thyroid volume of iodine sufficient group[(20.9 ± 6.1 )cm3] was higher than that iodine appropriate group [(17.9 ± 5.6)cm3,t =2.11,P ＜ 0.05].ConclusionsSufficient quantities of iodine intake may affect the thyroid of elderly people.Whether the quantity of iodine intake of the elderly population should be decreased or not need to be further studied.

OBJECTIVETo analyze the factors affecting pathologic complete response (pCR) to neoadjuvant chemotherapy (NAC) in breast cancer patients.

METHODSA retrospective cohort study was carried out to analyze the clinical data of 141 breast cancer patients treated with neoadjuvant chemotherapy. The factors affecting pCR and the changes of tumor receptor status before and after treatment were analyzed.

RESULTSAmong all the 141 patients, 21 patients (14.9%) achieved pCR. The rate of pCR achieved by regimens of anthracycline combined with taxane was higher (16.8%, 19/113) than that by anthracycline-containing regimens (7.1%, 1/14). The dose intensity of anthracycline had a significant correlation with pCR rate (P < 0.05). The pCR rate in the relative dose intensity of taxane ≥ 0.85 arm was higher than that of < 0.85 arm (P = 0.02). Eighty patients (56.7%) had completed more than 4 cycles of chemotherapy and the median time to achieve pCR was 6 (3 to 10) cycles. The pCR rate had a significant difference between patients < 6 and ≥ 6 cycles (7.1% vs. 22.5%,P = 0.01). Multivariate analysis showed that tumor size measured by palpation ≤ 5 cm and ≥ 6 chemotherapy cycles were significantly related with pCR rate (P < 0.05). In all the 21 pCR patients, the pre-treatment ER(-), PR(-), HER-2(-) statuses were in 14, 14 and 17 patients, respectively. The status of ER, PR, HER-2 of most patients (74.2%, 69.7% and 87.7%, respectively) was not changed after treatment. Among the patients with changes in receptor status, ER changed from negative to positive was in the majority (37.1%, 13/35 vs. 12.9%, 4/31, P < 0.05), and the percentage of changes in PR and HER-2 status had no significant differences.

CONCLUSIONSThe regimens of anthracycline combined with taxane can achieve a higher pCR rate. The lymph node and receptor status before therapy have no significant correlation with pCR. Patients who have primary tumor size ≤ 5 cm, ≥ 6 chemotherapy cycles and enough dose intensity are easier to achieve pCR. The receptor status before and after therapy should be determined, and according to any positive results, physicians can chose HER-2 targeted therapy and/or endocrine therapy after surgery to benefit the patients.

Aim To improve the rate of melanoma metastasis animal model and provide a reliable experimental modeling meth-od for the study of melanoma metastasis mechanism. Methods Five immunosuppressants were selected and then their targets were screened by network pharmacology. Intraperitoneal injection of immunosuppressants and intravenous injection of B16F10 cells were performed on C57BL/6 mice, then the mice were observed, and body weight were recorded daily. The contents of TNF-α, IL-6, IL-10, VEGF and MMP-9 in serum were measured with ELISA kit. The mice were dissected, then the metastasis situa-tion and the number of metastatic nodules in the lung and other organs were evaluated. HE-staining was involved to determine the morphology of metastatic tissues. Results The closeness centrality of cyclosporine and dexamethasone ranked the top and the targets were concentrated in lung and liver. No significant difference in body weight were observed after animal madel in-duced. The contents of TNF-α, IL-6 IL-10, VEGF and MMP-9 in the model group increased. The number of metastatic nodules in the lung significantly augmented with some kind of liver metas-tasis. HE-staining in the lung tissues showed that tumor presen-ted invasive growth. Conclusion By intraperitoneal injection of dexamethasone, the success rate of mice melanoma metastasis model can be greatly increased.

Screening aptamers using nano-materials ( such as graphene oxide, gold nanoparticle, carbon nano-tube, etc. ) that can quench fluorescence and absorb single stranded DNA using hydrogen bond, π-πbond, charge transfer, and other non-covalent ways to combine with ssDNA, but without other conformational DNA, can excellently separate specific aptamers from non-specific ones. In this case, we can shorten the cycle numbers, enhance the success rate, and reduce the labour intensity of systematic evolution of ligands by exponential enrichment ( SELEX) . Especially for small molecular target, due to its difficulty in immobilization and small size, it is difficult to use traditional methods such as SPR-SELEX or affinity-SELEX for screening. In this experiment, polydopamine nanospheres ( MNPs@PDAs) were used to screen the Lomefloxacin. Also, we used magnetic separation technique to screen small molecular target rapidly. The interaction between aptamer candidates and the target could be monitored by recovery ratio of ssDNA and the whole MNPs@PDAs-SELEX process was performed through seven-round selection. As a result, we successfully obtained the aptamer named AF-3 which could recognize the lomefloxacin with high affinity (KD=(17. 57±0. 5) nmol/L). This screening method based on MNPs@PDAs makes it a promising reagent in the efficient aptamers selection of other targets.
