Objective To investigate the correlation of serum alpha-fetoprotein (AFP) with clinical pathological factors and prognosis of hepatocellular carcinoma ( HCC ).Methods Two hundred and twenty patients with HCC who hospitalized in our hospital from January 2007 to June 2009 were enrolled in this study.The relationship of AFP levels before operation to clinical pathological factors such as pathological grade,tumor size,tumor encapsulation,tumor numbers,portal vein tumor thrombus,TNM stage and postoperative recurrence were analyzed.Results Serum AFP concentration before operation were related with tumor size ( x2 =11.76,P ＜ 0.05 ),tumor encapsulation ( x2 =17.07,P ＜ 0.05 ),portal vein tumor thrombus ( x2 =8.944,P ＜ 0.05 ),higher TNM stage ( x2 =4.929,P ＜ 0.05 ) and early postoperative recurrence rate ( x2 =5.569,P ＜ 0.05 ).However,it had no correlation with pathological edmondson grade tumor numbers.Conclusion HCC patients with high serum AFP concentration often has greater tumor without encapsulation,high occurrence rate of portal vein tumor thrombus and higher TNM stage,they are more likely to early postoperative recurrence.Serum AFP before operation is useful not only for diagnosis,but also as a prognostic biomarker to predict prognosis and recurrence.

Objectives:In situ coronary calcium is a specific anatomic marker of coronary atheroma. Electron beam CT is the first noninvasive method to determine coronary artery calcium. The aim of this study was to investigate the coronary artery calcium(CAC) in Chinese. Methods:Nine hundred and fifty-nine Chinese cases undergoing electron beam screening were divided into six age groups: ①younger than 29,②30～39,③40～49,④50～59,⑤60～69,⑥older than 70 years old, and were divided into another three groups according to coronary artery disease(CAD) symptoms.①symptomatic group: symptomatic patients with CAD;②doubtful symptom group: patients had atypical chest pain, but without sufficient information of angina,③asymptomatic group: patients without CAD symptoms. Results:① Prevalence of CAC and the total scores of CAC in asymptomatic men and women increased significantly with increased ages. ② There was a large increase in the prevalence of CAC in asymptomatic women between the age of 40～49 and 50～59. Conclusions: ①Coronary artery calcium prevalence increases with age in both men and women.②There is a marked difference in the prevalence of calcium between men and women.③The noninvasive detection of CAC by EBCT has certain prognostic and predictive value for coronary artery disease.

Background and purpose:Gastric cancer is one of the common malignancies seen in our country, most patients were diagnosed at a late stage. Surgery remains as one of the main treatments for the patients but the local local and regional failures were still high. The importance of the role of chemotherapy and radiotherapy has been investigated in the treatment of gastric cancer.We evaluated the efficacy and side-effects of CPT-11 combined with capecitabine for the treatment of advanced gastric cancer. Methods:Since May 2004 to May 2006, twenty patients with pathologically proved gastric cancer have been treated by CPT-11 plus capecitabine in our hospital. The regimen consisted of CPT-11 120 mg/m2 infusion at 1st day and 8th day, capecitabine 1000 mg/(m2?d) twice a day from 1st-14th day . The cycles were repeated every three weeks. All the patients were planned to receive at least 2 cycles of chemotherapy.Results:In 20 evaluable patients, 1 case had complete response; 8 case had partial response; 6 case had stable disease and 5 case with progressive disease. The response rate of the whole group was 45.0%(9/20); Clinical tumor control rate was 75.0%(15/20). The major toxicities were bone marrow suppression (52.1%) and reactions relative to digestive system (35.2%). All of complications were RTOGⅠ/Ⅱ degree.Conclusions:Combination of CPT-11 and capecitabine is effective for advanced gastric cancer and well tolerated by the patients. For the patients with either old age, poor general status or relapse after other chemotherapeutic regimen, the regimen could be the one of choice.

Epidemiological and animal studies have demonstrated that dietary lower intake of n-3 polyunsaturated fatty acids (n-3 PUFAs) and(or) higher intake of n-6 polyunsaturated fatty acids(n-6 PUFAs) leading to imbalance of their ratios are closely related to obesity.The mechanisms underlied are involved in PUFA′s effects on fatty acid synthesis and oxidation,adipocyte proliferation and differentiation and leptin expression.At transcription level,PUFAs can regulate the activities of peroxisome proliferator-activated receptors and CCAAT enhancer bin-ding proteins.

Objective:To investigate the expression of pre-B-cell leukemia homeobox 3 (PBX3) and the phosphatase and tensin homology deleted on chromosome 10 (PTEN) in cervical cancer and its relationship with the clinicopathologic characteristics and prognosis.Methods:Cervical cancer tissues and adjacent tissues of 85 patients with cervical cancer admitted to Xianlin Gulou Hospital from June 2014 to December 2018 were collected and the expression levels of PBX3 and PTEN were detected by immunohistochemistry. The univariate analysis and Logistic regression model were used to analyze the relationship between the expression levels of PBX3, PTEN and clinicopathologic features. Kaplan-Meier survival curve was used to analyze the relationship between the expression levels of PBX3, PTEN and prognosis.Results:The positive expression rate of PBX3 protein in cervical cancer tissues was higher than that in adjacent tissues: 38.82%(33/85) vs. 25.53%(20/85); the positive expression rate of PTEN protein was lower than that in adjacent tissues: 36.47%(31/85) vs. 98.82%(84/85), and there were significant differences ( P<0.05). The univariate analysis showed that the expression levels of PBX3 and PTEN were associated with clinical stages, degree of tumor differentiation, lymph node metastasis, vascular invasion, and degree of tumor invasion ( P<0.05). The multiple Logistic regression model showed that the clinical stages, tumor differentiation and lymph node metastasis were independent influencing factors for the positive expression of PBX3 or PTEN in cervical cancer tissues ( P<0.05). While 45.45%(15/33) of patients with positive PBX3 expression died, with a median survival of 31 months, and 25.00% (13/52)of patients with negative expression died, with a median survival of 38 months. Kaplan-rank test showed that the survival time in the patients with positive PBX3 expression and in the patients with negative expression had significant difference ( P=0.025). While 22.58%(7/31) of patients with positive PTEN expression died, with a median survival of 39 months, and 38.89%(21/54) of the patients with negative expression died, with a median survival time of 33 months. Kaplan-rank test showed that the survival time in the patients with positive PTEN expression and in the patients with negative expression had significant difference ( P=0.035). Conclusions:The expression of PBX3 is up-regulated and PTEN is down-regulated in cervical cancer. The expression levels of PBX3 and PTEN are related to clinical stage, tumor differentiation and lymph node metastasis. The prognosis of the patients with positive PBX3 expression is worse than that of the patients with negative expression, and the prognosis of the patients with positive PTEN expression is better than that of the patients with negative expression.

BACKGROUND:With respect to mesenchymal stem cels from other sources, synovial mesenchymal stem cels are rich in source, and moreover, the synovial tissue can regenerate quickly after partial hepatectomy and lead to fewer complications, in recent year, which have become a hot spot in stem cel research. OBJECTIVE:To observe the proliferation and directional differentiation of synovial mesenchymal stem cels from osteoarthritis patients. METHODS:Synovial mesenchymal stem cels were isolated and cultured. MTT assay was used to detect cel proliferation ability. Alkaline phosphatase activity was detected quantitatively at 7 days of osteogenic induction, and osteogensis-related gene expression was measured at 7, 14, 21 days of osteogenic induction. Alizarin red staining was performed at 21 days of induction. RESULTS AND CONCLUSION:(1) Passage 3 synovial mesenchymal stem cels proliferated faster, which were in latent period at 1, 2 days after inoculation, in logarithmic growth phase at 3-6 days, and then entered into the plateau phase at 7 days. (2) The activity of alkaline phosphatase was significantly higher in the induction group than the control group at 3, 7, 10 days after osteogenic induction (P < 0.05). The cels were positive for alizarin red staining at 21 days of osteogenic induction, and there were calcium deposits and calcium nodules in the extracelular matrix. (3) Bone-binding protein and Runx2 were visible at 7 days of osteogenic induction, and reached the peak at 21 days. These findings indicate that synovial mesenchymal stem cels from patients with advanced osteoarthritis have strong proliferation ability, which can differentiate into osteoblasts under in vitro induction.

Objective To study the positive incidence and clinical significance of auto-antibody of liver antigens in the serum of patients with autoimmune hepatitis diseases and viral hepatitis.Methods The serum samples with hepatic diseases were col-lected in Jiangyin People’s Hospital from 2010 to 2014 year.Patients were divided into three groups according to diseases:autoimmune hepatic disease group including autoimmune hepatitis (AIH)12 cases and primary biliary cirrhosis (PBC)36 case;viral hepatic group including HAV 23 cases,HBV 30 cases,HCV 14 cases and HEV 8 cases;normal control group 30 cases.Auto-antibody of live antigens AMA-M2,LKM-1,LC-1,SLA/LP,GP210 and SP100 were tested respectively by west-ern blotting assay.Results The positive rates of anti-AMA-M2,anti-LKM-1,anti-LC-1,anti-SLA/LP,anti-GP210,anti-SP100 were 16.7%,16.7%,8.3%,25%,0% and 16% respectively in AIH group,83.3%,0%,0%,0%,44.4% and 27.8% respectively in PBC group.Patients with viral hepatitis,one case were anti-AMA-M2 positive,one case were anti-GP210 positive and three case with positive anti-SP100.anti-AMA-M2,anti-GP210 and anti-SP100 were detected more fre-quently in autoimmune liver diseases group than viral hepatitis group (χ2 = 33.9,10.6 and 8.8,P < 0.05),anti-SLA/LP were detected more frequently in AIH group than PBC group (χ2 = 6.4,P <0.05),while anti-AMA-M2,anti-GP210 and were detected more frequently in PBC group than AIH group (χ2 =15.1 and 6.1,P <0.05).The positive rate of viral hepat-ic group was a very low frequency,there are little statistically significant difference (χ2 =1.1,P >0.05)compared with nor-mal control group.Conclusion The antibody of liver antigens are useful clinically for diagnosing and classifying autoimmune liver disease.

Objective To investigate the expression pattern of transcription factor,paired homebox 6(Pax6) in rat whisker hair follicle.Methods Whisker hair follicle was collected from 5 7-day-old SD rats.Immunohistochemical assay was carried out to detect Pax6 in the follicle.Pax6 mRNA expressions and its splicosome,Pax6-5a were detected by RT-PCR.Whisker hair follicle was primarily cultured to harvest rat hair follicle bulge cells.Then expressions of Pax6,CD34,?6-integrin,and Ki67 were detected in the obtained cells by immunofluorescent method.Results Pax6 was positively expressed in rat whisker hair follicle.The mRNA expression of Pax6-5a was stronger than that of Pax6.The primarily cultured cells expressed CD34 and ?6-integrin in the membrane.Pax6 was mainly located in the nuclei of the cells with Ki67,and little in the cytoplasm.The proliferative ability of the cells was correlated with the location of Pax6 protein.Conclusion Pax6 expresses in rat whisker hair follicle.Its expression patterns indicate that it may be involved in the formation and function of whisker hair follicle.

To observe the growth, expansion and differentiation of the cultured bone marrow stroma cell (BMSC) from Macaca Lrus, BMSC isolated from adult Macaca Lrus were cultured with the culture medium confected by ourselves and were induced with some cytokines such as LIF and bFGF. The results showed that the BMSC could proliferate and generate Nestin positive clones when they were cultured in vitro. After subculture, these cells could grow rapidly and differentiated into neuron like cells and astrocyte like cells further, which expressed GFAP or NSE antigen respectively. Therefore, these BMSC possess renewal and differentiation abilities. On the other hand, the culture method we used in this experiment is suitable for culture of BMSC in vitro. The BMSC might be used as the seed cells of the neural stem cells.
