There are many kinds of research methods in proteomics of breast cancer,one of them is mass spectrometry and have made a great progress.With more progress in proteomics studies,diagnosis and prognosis of the specific markers for breast cancer continue to be found,there would be great benefits for patients with breast cancer in diagnosis and prognosis.

Objective Wnt signal is very important to control the gastrointestinal mucosal proliferation, but its role in the gastric mucosal proliferation after acidified ethanol injury is not clear yet,neither is the relationship with cyclooxygenase 2 (COX-2). Methods X-gal staining was used to measure the expression of Wnt signaling; Western blot and RT-PCR were used to measure the expression of TCF4 and P-Catenin in the gastric mucosa before and after acidified ethanol injury. We also used TOP/flash plasmid to further indentify the relationship between COX-2 and Wnt signal pathway. Results After acidified ethanol injury, the expression of LacZ signal, β-Catenin and TCF4 increased only in the wild type mouse. The expression of β-Catenin and TCF4 protein increased about (3.52 ±0.52) times and (3.02 ±0.62) times separately, and the expression of β-Catenin and TCF4 mRNA increased about (19. 85 ±3.63) times and (17.82 ±4.82) times separately. Without ethanol injury, the expression of TOP/flash plasmid was inhibited by COX-2 inhibitor (NS398) about 80% and promoted by prostaglandin E2(PGE2) about 50%.After 1% ethanol injury, the expression of plasmid was inhibited by NS398 about 25% ; on the contrary,PGE2 promoted the expression about 10%. Conclusion Wnt signal in gastric mucosa is activated after acidified ethanol injury. COX-2 may work through modulating Wnt signal to control the proliferation of gastric mucosa.

Objective To explore the incidence and distribution features of neonatal phenylketonuria(PKU) and congenital hypothyroidism(CH) in Lianyungang area.Methods The heel blood samples dried on filter paper was collected from newborns after 72 hours.As the screening indicators,PKU was detected through serum phenylalanine concentration(Phe) detection by Guthrie′s bacterial inhibition assay and CH was detected through serum thyroid stimulating hormone(TSH) levels detection by time-resolved fluorometry(TRFIA) or enzyme linked immunosorbent assay(ELISA).Results Sixty-four children with CH were diagnosed and the rate of CH was 1∶2423,41 patients were examined by thyroid gland nuclein kinescope picture,among which there were 23 patients whose thyroid glands were unusal.These patients lived in 45 towns(streets),which had no difference between men and women,city and country side.A couple of twins were screened for CH;15 cases of PKU was detected with an incidence of 1∶10 339.These patients′ parents were neither consanguineous marriage nor dominance hereditary family history.Their physical and mental development were similar to the same age children after interventive treatment.Conclusions The distribution of CH and PKU is diffuse in Lianyungang.Neonatal screening is the only valid means to find patients with CH and PKU.

Objective To establish an in vitro skin sensitization test,human cell line activation test (h-CLAT),based on THP-1 cell line (a human acute monocytic leukemia cell line),and to assess the sensitizing potency of plant raw materials of chemical and cosmetic products by this in vitro skin sensitization test.Method THP-1 cells were cultured in vitro and exposed to 11 reference skin sensitization chemicals and 9 samples,by monitoring the cell viability,cell surface marker CD54 /CD86 and relative fluorescence intensity of cells surface after the cells was exposures to the substances,and to discover whether there is a positive reaction.At the same time,Buehler test was used to validate the results of samples tested by h-CLAT.Results 11 reference chemicals were distinguished correctly by h-CLAT.Among the 9 samples tested,7 samples were recognized as negative sensitizer and 2 plant extracted substances were identified as suspicious skin sensitizer.The qualitative classification of the 9 samples by h-CLAT test was consistent with the results obtained by animal test.Conclusions The h-CLAT-in vitro test can be used to replace some animal tests for the prediction of soluble skin sensitizing substances.

BACKGROUND:Tai Chi exercise can relax the affected muscle of patients, increase muscle flexibility and strength, promote normal movement patterns of stroke patients, inhibit abnormal posture and spasm patterns, improve patient motion control and balance function. OBJECTIVE:To systematicaly assess the effectiveness of Tai Chi on the movement, emotional disorder and quality of life in patients with stroke. METHODS: Al extracted data from databases of PubMed, EMbase, Web of Science, EBSCO, Google Scholar, CNKI, VIP and Wangfang were obtained, which were the randomized controled trials addressing the effects of Tai Chi on the movement, emotional disorder and quality of life in patients with stroke. The retrieval time was from database establishment to July 1st, 2015. According to the inclusion and exclusion criteria, two reviewers independently screened, extracted data and assessed the methodological quality of the included literatures. Then the meta-analysis was conducted using RevMan 5.3 software. RESULTS AND CONCLUSION:A total of 15 randomized controled trials involving 1016 patients were included. The results of Meta-analysis suggested that: Tai Chi was superior to the conventional rehabilitation in improvement of balance function [mean difference (MD)=7.87, 95% confidence interval (CI) (4.56, 11.18),P < 0.000 01], gait speed [MD=0.27, 95%CI (0.04, 3.94),P=0.02], anxiety [standardized mean difference (SMD)=-0.47, 95%CI(-0.89,-0.04),P=0.03] and quality of life [SMD=0.65, 95%CI(0.10, 1.19),P=0.02], and there were statistical differences. But there was no statisticaly significant difference in the improvement of depression and functional walking ability. These findings indicate that Tai Chi is superior to the conventional rehabilitation in the improvement of balance function, gait speed, anxiety and quality of life. However, large-sample, high-quality randomized controled trials are needed to provide more reliable evidence for the effect of Tai Chi in depression and functional walking ability.
