HIC1 (hypermethylated in cancer 1) encodes a transcriptional repressor,and extensively resides in various kinds of normal tissue.HIC1 gene is located in chromosome 17p13.3,in which loss of heterozygote or super-methylation is frequently found in a variety of human cancers.As a new tumor marker,HIC1 has been confirmed down-regulated in a wide variety of solid cancers because of HIC1 promoter hypermethylation,and may be associated with tumor prognosis.As a tumor suppressor,HIC1 participates in the development of tumor process through various ways,and is involved in cell proliferation,tumour growth,and angiogenesis.Therefore,the abnormal hypermethylation or the loss of expression of HIC1 in tumor cells or abnormal function could be one of the important mechanisms of tumor development,and may become a new potential therapeutic targets for cancer.

Objective To evaluate the approaches of percutaneous trans-hepatic stent for relieving malignant biliary obstruction and its clinical effect. Methods 20 stents were set up in bile duct to treat malignant biliary obstruction in 18 cases using two steps under x-ray fluoroscopy. After the stents set up successfully, the contrast agent was injected through the long sheath in order to find out the expansion and expedition of the stent. The stents were provided by Micro-Tech co.1td.(Nanjing). The patient’s jaundice, liver function and amylase (AMY)levels were observed after the procedure and all the patients were followed up for three to eleven months. Results Twenty stents were placed in 18 patients successfully in one time.STB , ALT, AST, r-GT and ALP decreased 66.27%, 57.83%, 62.21%, 44.74% and 47.57% respectively one week after the procedure. Early complications included hyperamylasemia , acute pancreatitis,hernobilia, bile leakage,ect.Late complications were displacement and restenosis of the stent . A patient died due to failure of heart and lung. Conclusion The percutaneous transhepatic insertion of biliary stent is an effective method in relieving malignant obstructive jaundice.

Objective To explore the clinical value of combined detection of serum beta human chorionic gonadotropin (β-hCG),estradiol (E2),progesterone (P) and antiphospholipid antibodies (ACA) in predicting the outcomes of early threatened abortion.Methods 80 pregnant women were chosen from six to eight weeks singleton pregnancies,50 cases of threatened abortion and 30 cases of normal pregnancy.The serum levels of β-HCG,estradiol,progesterone and ACA-IgG,ACA-IgM and ACA-IgA were detected.The threatened abortion patients were given intramuscular progesterone 20 mg/day/time for 1 week,then,the pregnancy outcomes were analyzed and the serum levels of β-HCG,estradiol and progesterone were explored.Results The serum β-HCG,estradiol and progesterone of the threatened abortion group [(5 140.77 ± 2 365.47) IU/L,(680.28 ± 306.06) pg/mL,(15.59 ± 3.65) pg/L]were lower than those of the normal pregnant women [(14 520.4 ± 11 016.24) IU/L,(1 142.81 ± 670.57) pg/mL,(27.6 ± 4.78) pg/L] (t =3.224,P =0.003 ; t =2.43,P =0.022 ; t =7.72,P =0.001).According to pregnancy outcome,patients with threatened miscarriages were divided into the two groups,including 45 patients with continuing pregnancies and 5 patients with inevitable miscarriages.The serum levels of β-HCG,estradiol and progesterone in ongoing pregnancies group [(10 829.42 ± 6 926.28) IU/L,(832.9 ± 397.91) pg/mL,(25.62 ± 4.51) pg/L] were higher than those in inevitable miscarriages [(6 310.14 ± 2 593.19) IU/L,(487.14 ± 275.47) pg/mL,(13.6 ±4.84) pg/L] (P ＜ 0.05) ;The serum levels of ACA-IgG,ACA-IgM and ACA-IgA in 80 cases tested,only 2 cases who appeared in the threatened abortion group were detected with the positive of serum ACA-IgG,accounted for 4％ (2/50) (x2 =68.05,P =0.000),occurred spontaneous abortion in the end.Conclusion Combined detection of serum ACA,β-HCG,estradiol and progesterone may be helpful for prognosis of threatened abortion.However,the clinical predictive value of ACA needs further study in the early threatened abortion.

Objective To investigate the differences of related clinicopathologic features in colorectal cancer (CRC) patients with or without Type 2 Diabetes Mellitus (T2DM).Methods Using case-control studies,retrospective analysis of colorectal cancer of 60 patients with colorectal cancer hospitalization and 32 cases of T2DM were taken.The clinical data,histological grade,tumor size,clinical stage and lymph node metastasis pathology indicators conditions of the hospitalized CRC patients with or without type 2 diabetes were compared.Results The average age of the team with hospitalized CRC patients combined with type 2 diabetes is (64.90 ±8.87),fasting blood-glucose is (8.33 ±4.66) mmol/L.BMI and TG are (25.77 ±3.80) kg/m2 and (1.71 ±0.85) mmol/L which were all higher((54.70 ± 11.62),(5.85 ±0.88) mmol/L,(23.57 ±3.64)kg/m2,(1.33 ± 0.83) mmol/L) than patients without DM.There were significant differences between two groups (t =4.324,t =2.982,t =2.728,t =2.045,respectively,P ＜ 0.05).However,total cholesterol,high density lipoprotein-cholesterol and low density lipoprotein-cholesterol had no significantly differences with those patients without DM (P ＞ 0.05).There were no significant differences of clinicopathologic features between CRC patients with and without DM (P ＞ 0.05).Conclusion There is a certain correlation between CRC and DM,DM increases the risk of colorectal cancer so diabetes patients should be early screened for colorectal,with a view to early detection,treatment and improve the prognosis.

ObjectiveTo investigate the control rate and influence factors of glycolated hemoglobin A1C(HbA1c) of type 2 diabetes in Baoding city community.MethodsA cluster-randomized study was conducted and three communities were selected randomly.The study involved all of people aged 45 years old and above in the three communities.The type 2 diabetic patients diagnosed before,were recorded through the cross section study.Then the questionnaire was finished.All diabetic plasma HbA1c was determined by HPLC method.ResultsEighty-seven patients with HbA1c≤7％ were only 18.6％ in all diabetic patients.As the plasma level of HbA1c increased,occurrences of macroangiopathy and microangiopathy were both increased,by the trend test.Logistic regression analysis showed that therapeutic measures and knowledge about diabetes were main influence factors of achieving the hemoglobin Alc target of ＜7％ in type 2 diabetes.ConclusionThere were low HbA1c control in diabetic patients of Baoding community,and knowing diabetes well and receiving insulin treatment might decrease HbA1c level apparently.

Totally 177 individuals (87 males and 90 females), who took abdominal computer tomography were enrolled. Anthropometric surrogates such as abdominal height( AH), waist circumference( WC), body mass index(BMI), and waist to height ratio(WHtR) were measured. Correlations between AH, WC, BMI, and WHtR with visceral abdominal fat were analyzed, and receiver operating characteristic curves ( ROC) were prepared for detecting abdominal adiposity at or beyond 80cm2 using lumbar vertebra 4-5 cross-section visceral fat areas as the screening cut-point within gender separately. Youden′s index was used to determine cut-off values of AH, WC, BMI, and WHtR by which to classify excess abdominal fat. 70(80. 5% ) males and 59(65. 9% ) females had abdominal obesity. Compared to other anthropometic indicators, AH presented the highest correlation with visceral adipose fat. The pearson correlation efficiencies were 0. 825 and 0. 732, the cut-off points were 20 cm and 20. 3 cm in male and female respectively. After controlling for age, receiver operating characteristic analysis showed that AH, followed by WHtR, outperformed WC and BMI in identifying central obesity participants. Optimal cut-off values of the physical anthropometric indices to indentify abdominal adiposity were 20 cm(AH), and 91 cm(WC) 25 kg/ m2 (BMI), and 0. 52(WHtR) for men, and 20. 3 cm(AH), 86. 5 cm(WC), 25 kg/ m2(BMI), and 0. 54(WHtR) for women. AH is effective for predicting visceral adiposity and might be considered the best predictor of abdominal obesity at a cut-point of 20cm in Chinese adults.
