Type 2 diabetes mellitus is a progressive process. With the course of the disease progress, microvascular and macrovascular complications always happen. Thrombotic events caused by macrovascular complications, including coronary heart diseases and cerebrovascular diseases, are the main fatal factor for the patients with type 2 diabetes. Endothelial dysfunction, coagulative activation, impaired fibrinolysis, together with hyper-reactive platelets contribute to the diabetic prothrombotic state, which is strongly related to the macrovascular complications. In particular, the hyper-reactive platelets play a fundamental role among them. Type 2 diabetes is characterized by several metabolic dysfunctions such as hyperglycemia, insulin resistance and shortage, oxidative stress, systemic inflammation, obesity, and dyslipidemia. These metabolic dysfunctions work together to promote the formation of hyper-reactive platelets, which are distinctive in type 2 diabetes. The regular antiplatelet drugs, like aspirin, show limited inhibitory effect on them. Hence, studying the mechanism behind the hyper-reactive platelets could provide a brand-new view on the prevention of macrovascular complications and cardiovascular events in type 2 diabetes.

Ovarian cancer is the most fatal malignant tumor in female reproductive system tumors.In most women, it is diagnosed in a late stage, which largely leads to the poor prognosis of ovarian cancer.Breast cancer susceptibility gene (BRCA) is an important DNA homologous repair gene, which plays a major role in the normal cellular DNA repair mechanism.Its mutation will lead to homologous recombination defects, which will affect the stability of the genome and lead to occurrence of tumors.In recent years, BRCA genetic testing has become a key step in the risk assessment, prognosis, treatment and prevention of ovarian cancer.

Objective: To analyze the distribution of HCV genotype in eastern Zhejiang Province and its correlation with sex, age, viral load, antiviral effect and so on. Methods: A total of 501 cases of HCV infection seen in Ningbo No. 2 hospital from January 2011 to April 2018 were included. The HCV genotypes and HCV RNA were detected by gene chip method and RT-PCR respectively. The liver function and blood routine tests were performed and the APRI index was calculated. The factors affecting the SVR were analyzed for the patients who were partially treated with pegylated interferon and ribavirin (PR). Results: The HCV genotypes of 501 cases were 1b、6、2a、3a、3b、1a from the higher to lower ranks, and genotype 1b was more than 50%.The distribution of HCV genotypes in different age groups was significantly different (χ²=95.433, P<0.001). The age of patients with 1a, 1b and 2 A was significantly higher than that of 3a, 3b, and type 6 (F=11.879, P<0.001). There were significant differences in viral load, AST, PLT and APRI index among different genotypes (F=2.920, χ²=12.400, F=6.294, χ²=12.700, all P<0.013), but ALT had little difference (χ²=7.994, P>0.157); 179 patients with PR standard regimen were followed up. The result showed that there was no significant difference in the overall efficacy of different genotypes (χ²=6.598, P=0.252), but the rate of sustained virological response in type 3 A was significantly higher than that of the 1b type (χ²=4.193, P=0.041). Conclusions The HCV genotypes are mainly 1b and 6 in eastern Zhejiang Province. There were significant differences in age, viral load, AST, PLT and APRI indices among patients with different HCV genotypes, and the therapeutic effect of PR regimen was better for genotype 1b than that of 3a.

Geographic tongue, also called benign migratory glossitis, is a common and superficial benign inflammatory disorder that affects the tongue epithelium. The majority of geographic tongue lesions typically manifest as irregular central erythematous patches. These lesions, which are caused by the loss of filiform papillae, are defined by an elevated whitish band-like border that can change location, size, and pattern over a period of time. Histological observations of the oral mucosa affected by geographic tongue revealed nonspecific inflammation. Some reports described cases of migratory stomatitis, wherein lesions simultaneously manifested on the extra lingual oral mucosa. This condition is also called ectopic geographic tongue, which is clinically and histologically similar to the type normally confined to the tongue. In most cases, patients are asymptomatic and do not require treatment. The condition may spontaneously exhibit periods of remission and exacerbation with good prognosis. The specific etiology of geographic tongue remains unknown. Geographic tongue is age-related and is prevalent among young individuals. Various etiological factors that have been suggested in literature include immunological factors, genetic factors, atopic or allergic tendency, emotional stress, tobacco consumption, hormonal disturbances, and zinc deficiency. Geographic tongue may coexist with other disorders, such as fissured tongue, psoriasis, diabetes mellitus, gastroin- testinal diseases, burning mouth syndrome, and Down syndrome. Experts currently disagree on whether geographic tongue is an oral manifestation of psoriasis. Moreover, some scholars suggest that geographic tongue is a prestage of fissured tongue. The objective of this review is to summarize current research on risk factors of geographic tongue.

Objective To evaluate the efficiency of second trimester screenings for Down syndrome using alpha-fetoprotein and β-human chorionic gonadotropin duplex.MethodsPregnant women of south Zhejiang were screened for Down syndrome fetuses by maternal alpha-fetoprotein and β-human chorionic gonadotropin duplex during second trimester.The high-risk women underwent prenatal diagnosis by amniocentesis,cell culture and chromosome analysis.The newborns followed up by the maternal and child tertiary health care network and suspected to have Down syndrome were diagnosed by peripheral blood chromosome analysis.Statistical analysis was performed using two-sample t test and x2 test.Risk probability of Down Syndrome was calculated by random screening software. Results From Oct.2007 to May 2009,1130 of 32 188 singleton pregnant women in second trimester received prenatal screening were discovered with high risk(≥1 ∶ 270).Prenatal diagnosis was performed in 90.79％ cases (1026/1130) of high risk women and seven fetuses were diagnosed as Down syndrome by amniotic fluid chromosome analysis,and the pregnancies were terminated.Among the other 104 cases without prenatal diagnosis one Down syndrome baby was delivered.Six of 31 058 pregnancy women with low risk delivered Down syndrome babies with the incidence of Down syndrome of 0.19‰ (6/31 058).Detection rate of second trimester screenings for Down syndrome using alpha-fetoprotein and β-human chorionic gonadotropin duplex was 57.14％(8/14).False positive rate was 3.48％ (1122/32 188).Positive predictive value was 7.08‰(8/1130).During the same period,there were 23 813 pregnant women who didn't receive screening and 15 fetuses with Down syndrome were diagnosed after birth.There was no statistical difference in the prevalence rate of Down syndrome between those pregnant women who received prenatal screening or not [0.43‰ (14/32 188) vs 0.63‰ (15/23 813),x2 =1.004,P＞0.05].The prevalence of Down syndrome was 0.52‰ (29/56 001) in this area. ConclusionsThe prenatal screening and diagnosis could reduce the birth rate of Down syndrome patients.However,detection rate,false positive rate and positive predictive value of which were lower than reports in other studies.It's possible that the reference data might be not suitable for Chinese.

Objective To evaluate the effect of sustained silencing Forkhead box Ml (F0XM1) gene by short-hairpin RNA (shRNA) expression vector on cell growth of hepatocelluar carcinoma (HCC) in vitro.Methods Four shRNA expression vectors targeting different sequences of human F0XM1 mRNA were constructed.The expression vector with the best interfering effect and the negative control plasmid were used to transfect HCC cell line QGY-7703, stably transfected cell clones were selected by neomycin (G418).Cell growth was evaluated by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay and colony formation was assessed by clonogenic assay.Cell apoptosis was detected by double staining with APC conjugated Annexin V and PI.Results F0XM1 protein was detected with different levels in all these studied human cell lines.The expression vector shRNA-1026 exhibited excellent interference effect after transient transfection, which showed 38.5% and 53.2% reduction of FOXM1 mRNA and protein level respectively.The growth of QGY-7703 cells was inhibited after stable inhibition of FOXM1 expression by shRNA-1026, which was indicated by decreased absorbance value of the test group after culture for 48, 72 and 96 h compared to control group (t = 10.830,3.578 and 5.734 respectively, P ＜ 0.05).Stable inhibition of F0XM1 also led to reduced colony formation ( t = 5.336, P ＜ 0.05 ) and increased apoptosis of QGY-7703 cells in comparison to control cells (t = 6.827, P ＜ 0.05 ).Conclusions Stable silencing F0XM1 gene by shRNA suppresses the growth of HCC cells in vitro.

Objective To screen for and validate unknown tumor suppressor genes (TSGs) in sporadic colorectal cancer (CRC) patients.Methods Through loss of heterozygosity (LOH) analysis on chromosome 10 in sporadic CRC,we have found D10S185 (10q23.31-24.33 ) exhibit a higher LOH frequency in our previous study.In present study,we screen for unknown TSGs in this region through the microarray.The expression of the new gene was analyzed by quantitative real-time polymerase chain reaction (qRT-PCR).RT-PCR,immunohistochemistry and Western blot were done in colorectal cancer tissues with their pair-matched normal tissues in 50 cases to validate the results of microarray.Results Through the microarray-based high throughput screening,we found 4 significant down-regulated genes:PLCE1,CPEB3,NKX2-3 and SEMA4G,among them the down-regulation of PLCE1 was most significant.The results of qRTPCR were in relative agreement with the DNA microarray data.RT-PCR,immunohistochemistry and Western blot also showed that the expression of PLCE1 was at low levels in 46％ cancer tissues compared with normal tissues,more frequent in the poor differentiation tumor in patients under age 60 years (P ＜ 0.05 ).Conclusions This study demonstrated that down-regulation of PLCE1 was related to the tumorigenesis of sporadic colorectal cancer.PLCE1 might play a suppressive role in the development of colorectal cancer.
