Objective To investigate the methylation status in the promoter region of Dickkopf-3 (Dkk3) gene in patients with myelodysplastic syndromes (MDS),and to initially explore the relationship between the methylation of this gene and survival time.Methods Methylation-specific PCR (MSP) was applied to measure the promoter methylation of Dkk3 gene in 43 bone marrow or peripheral blood samples of MDS patients.As controls,70 normal peripheral blood samples from general outpatients were examined.Results In 43 patients with MDS,7 patients (16.3 ％) showed Dkk3 gene methylation.And 5 of them were semi-methylation status,2 of them were exhaustive methylation status.In 70 controls,1 showed Dkk3 gene semi-methylation.The frequency of methylation in MDS patients was significantly higher than that of controls (x2 =8.93,P =0.005).In the Dkk3 methylation group,2/7 were from bone marrow and 5/7 were from peripheral blood.Meanwhile,2 patients were RA,1 patient was RCMD,4 patients were RAEB.There was no significant difference between the different sample source (bone marrow or peripheral blood) for the results of the methylation status (x2 =0.051,P =0.821).Either between the different sex,age,type,chromosome and WPSS score (P ＞ 0.05).The progress of disease didn't influence the methylation frequency (P ＞ 0.05).The smvival analysis showed no relationship between the methylation of this gene and smvival time.Conclusions In this MDS group,there is high level of methyl-modification in Dkk3 gene.The methylation of Dkk3 might be one of the molecular mechanisms that contribute to the progress of patients with MDS.The peripheral blood sample maybe a better substitute in detective of Dkk3 with MDS.

Objective To explore the outcome of monoclonal gammopathy of undetermined significance (MGUS). Methods The data from 14 MGUS patients in our hospital including clinical features, outcome and change of M protein concentration were analyzed retrospectively. Results The MGUS didn't have the clinical manifestations of multiple myeloma (MM), the time of outcome from MGUS to MM was about 4-20 years (mean time, 10 years). The most types of MM were IgA and IgG, 6 cases were IgA type, 6 cases were IgG type and 2 cases were light chain type. The concentration of immune globulin in general showed an upward trend year by year. A few showed fold lines ascend. Conclusions The elevated monoclonal immunoglobulin may develop into MM after many years. We must follow up frequently to avoid error diagnosis and missed diagnosis.

The growth changes of glutathione (GSH) and ergosterol in Saccharomyces cerevisiae (CICC1447 and CICC1339) were detected under 0.5Mpa pressure with compressed high-pure air (O-2∶N-2=21∶79). The results showed that logarithmic phases of the two strains were delayed; their biomass and special growth rate were lower than those of control sample (0.1MPa) and the double time were prolonged under 0.5MPa. High-pressure could increase the content of GSH obviously, compared to ambient atmosphere control samples. When the holding time was 3h, the content of GSH and ergosterol in CICC1447 increased 42.6% and 20.1%, respectively. However, the content of GSH in CICC1339 increased 58.7% when the holding time was 6h, while ergosterol content reduced. The results indicated that different yeast strains have different stress-response mechanism to copy with high-pressure shock.

Objective To systematically evaluate the clinical efficacy of Lanqin Oral Liquid(LOL)and ribavirin on infantile hand-foot-mouth disease(HFMD).Methods The randomized controlled trials(RCT)of LOL and ribavirincombined for treating HFMD were retrieved from EMbase, PubMed, CNKI, CBM and VIP(from establish to Oct 2014), the methodological quality of included literature was evaluated, and data analyses were performed with RevMan 5.2 software.Results Fifteen studies involving 2 016 patients were ultimately identified.The meta-analysis results showed that the effective rate of LOL group was superior to that of the control,OR(95%CI)was 5.80 (3.94, 8.52), and there were significant differences in the antifebrile time, erythra regression time, herpes regression time and oral ulcer regression time between the groups,MD (95%CI): -1.29 (-1.45,-1.13), -1.88 (-2.44,-1.33), -1.57 (-2.36,-0.78), -1.57 (-2.07,-1.08), respectively. Conclusion Based on the present clinical evidence, the meta-analysis results indicate that LOL and ribavirin treating HFMD is effective and safe. However, due to the uneven quality of these included studies, this conclusion need more large sample size and high-quality clinical RCTs to be confirmed.

Objective To study the inhibitory effects of TPP,a desmosdumotin-C B ring para-fluoro modified derivative,on human breast cancer MCF-7 cell proliferation,and investigate the possible mechanisms.Methods MTT assay was used to measure the proliferation suppression of MCF-7 cells after treated with 1.0,2.5,5.0,10.0,and 20.0 μg/mL TPP for 48 h,and then the cell apoptosis rate and expression rate of NF-κB P65 positive cells were tested by flow cytometry after 20.0 μg/mL TPP treatment for 0,24,and 48 h.Results MTT assay showed that,after treatment for 48 h,1.0,2.5,5.0,10.0,and 20.0 μg/mL TPP all exhibited the inhibitory effects and showed a dose-dependent relationship.Flow cytometry results showed that 20.0 μg/mL TPP induced cell apoptosis after treatment for 24 and 48 h.TPP (20.0 μg/mL) significantly reduced the rate ofNF-κB P65-positive cells in MCF-7 cells after treatment for 48 h.Conclusion TPP could inhibit the proliferation of MCF-7 cells,which may be induced by cell apoptosis.Down-regulation of NF-κB is possible to be related with apoptosis.

Objective To compare the saccharometabolism with the pancreatic islets functions and insulin resistance index in children with severe stress. Methods Thirty children with severe stress and 30 healthy children in control group were tested. The levels of fasting blood glucose (FBG), fasting insulin (FINS) and fasting C - peptide (FCP) were detected by radioimmunoassay respectively and insulin sensitivity index (ISI), insulin resistance index (IR) and fasting blood cell function index (FBCI) were calculated statistically. Results There were significant differences between the children with severe stress and the normal controls in the levels of FINS, FCP and FBG,(all P0.05). Conclusion There is insulin resistance with the significant decrease in the insulin sensitivity index and significant increase in insulin resistance index in the children with severe stress, which may cause the disorder in glucose metabolism in children with severe stress.

Coronary artery disease (CAD) is one of the leading causes of death. Safflower attracts great attention owing to its anti-ischemia/reperfusion injury effect. Ninety-three patients with CAD were included and randomized into safflower treatment group, PCI group and control group. Low-dose dobutamine stress echocardiography (DSE) was performed to measure end-systolic volume (ESV), end-diastolic volume (EDV), left ventricular ejection fraction (LVEF) and wall motion score index (WMSI) to determine the recovery of hibernating myocardium and cardiac function in all patients before treatment and after 3-month follow-up. The study was to investigate the effects of safflower on hibernating myocardial revascularization and cardiac function. It was found that LVEF was significantly improved, while the ESV and WMSI were significantly reduced after 2-week treatment in safflower and PCI treatment groups. No significant differences were found between safflower and PCI treatment groups in ESV, EDV, WMSI and LVEF after treatment Safflower injection effectively improved hibernating myocardial function.

ObjectiveTo investigate the methylation status in the promoter region of secreting frizzled related protein 2 (SFRP2) gene in patients with myelodyplastic sydrome (MDS) and to initially explore the relationship between the methylation of this gene and prognosis/survival time.MethodsMSP method was applied to examine the promoter methylation of SFRP2 gene in 43 bone marrow or peripheral blood samples of MDS patients.As controls,70 normal peripheral blood samples from volunteers of general outpatients were examined.Then some of the patients were followed up.ResultsIn 43 patients of MDS,10 samples (23.3 ％)showed SFRP2 gene methylation,and all of them were semi-methylation status.In 70 controls,no sample showed SFRP2 gene methylation.The frequency of SFRP2 gene methylation in MDS patients was significantly higher than that in controls (x2 =17.86,P ＜0.0001).Of the 10 SFRP2 gene methylation samples,5 were bone marrow samples and 5 were peripheral blood samples.In this group of patients,3 patients were diagnosed as RA,1 patient was diagnosed as RAS,2 patients were diagnosed as RCMD,3 patients were diagnosed as RAEB and 1 patient was diagnosed as MDS-U.There was no significant difference between the different sample source (bone marrow or peripheral blood) for the results of the methylation status (x2 =0.912,P ＞0.05).Either no significant difference between the different sex,age,type,chromosome and WPSS score (all P ＞0.05).The progress of disease didn' t influence the methylation rate (P ＞0.05).16 patients accepted follow-up and 11patients died,3 patients went to AML.2 died patients showed SFRP2 gene methylation.The survival analyses showed no relationship between the methylation of this gene and survival time(x2 =0.022, P ＞0.05).ConclusionIn this MDS group,there is a high level of methyl-modification in SFRP2 gene.The methylation of SFRP2 may be one of the molecular mechanisms that contribute to the progress of patients with MDS.The peripheral blood sample maybe a better substitute in detection of SFRP2 with MDS.

OBJECTIVETo evaluate the value and inadequacy in clinical practice of the concept of gastric high-grade intraepithelial neoplasia (HIN).

METHODSForty-five cases with gastric HIN diagnosed by the esophagogastroduodenoscopy (EGD) biopsy were treated from 2003 to 2009. The clinical and histopathological data were analyzed retrospectively.

RESULTSRadical surgeries were successfully performed on all the patients, among whom 33 underwent distal subtotal gastrectomy, 3 proximal partial gastrectomy, 7 total gastrectomy, and 2 endoscopic mucosal resection. In postoperative pathological examination, only 15 cases (33.3%) were HIN, while 14 cases (31.1%) were found to be early gastric cancers, and 16 (35.6%) were advanced cancers. Twelve(40.0%) out of 30 cancers had regional lymph nodes metastasis. When the maximum diameter of the HIN lesion was greater than 3.0 cm, or when ulcer or the features of poorly-differentiated carcinoma or signet-ring cell carcinoma were present in preoperative biopsy, the likelihood of cancer in postoperative pathological examination was higher (P<0.05), and when malignancy was confirmed, the presence of the features above was associated with lymph nodes metastasis and advanced cancer.

CONCLUSIONSCarcinoma is identified in a large proportion of patients with gastric HIN by the EGD biopsy. Lymph nodes metastasis or advanced cancer may be detected in these cases. Cautions must be taken when the new concept of HIN is widely used for diagnosing gastric lesion. Radical resection should be considered when the maximum diameter of the HIN lesion is greater than 3.0 cm, or when ulcer, or the feature of poorly-differentiated carcinoma or signet-ring cell carcinoma are present in the EGD biopsy.
