Liver transplantation is an essential treatment of primary liver cancer,but the postoperative high risk of recurrence and metastasis has seriously affected the effect of liver transplantation.With the development of molecular biology,researchers have found numerous molec-ular markers potentially related to the recurrence and metastasis of liver cancer after liver transplantation.These markers,including genes, proteins,tumor markers,and serum viruses,are summarized,and their predictive values for tumor recurrence and metastasis after liver transplantation are analyzed.A growing number of molecular markers have been found,but which is not enough for clinical guidance.There-fore,more studies are needed to identify appropriate molecular markers of tumor recurrence and metastasis after liver transplantation.

Objective:In 2003,a survey of the manpower of pediatric dentists was made in China in order to provide basis for database. Methods:Questionnaires were distributed to dentists presenced the 5th conference of pediatric dentistry in China,and 139 available answers were analysis. Results:In those 139 pediatric dentists, with a mean age of 38.2?8.7,females were significantly more than males, and 89.9% dentists had bachelor, master or doctor degree. Significant relations were found between self-estimate ability of dentists and their length of work, degree, character of clinic.Conclusion:To date, the team of pediatric dentists begins to take shape, the structure of age and education are rational, but the number of them is insufficient and it is necessary to improve the basic and continuing education.

To build the Dendrobium nobile -T2DM network, and elucidate the molecular mechanism of D. nobile to type 2 diabetes (T2DM). Collect the chemical composition of D. nobile and the targets on T2DM by retrieving database and documents, build the network of D. nobile to T2DM using the entity grammar systems inference rules. The molecular mechanism of D. nobile to T2DM includes: (1) regulating lipid metabolism by lowering triglyceride; (2) reducing insulin resistance; (3) protecting islet cells; (4) promoting the glucose-dependent insulin tropic peptide (GIP) secretion; (5) inhibiting calcium channel. Under the guidance of network pharmacology, through entity grammar systems inference rules we elucidate the molecular mechanism of D. nobile to T2DM, and provide the basis for the further development of health care products based on D. nobile.

Objective:To analyze the distribution of UGT1A1 gene polymorphisms in Chinese Han patients with extensive-disease small cell lung cancer(ED-SCLC),and evaluate the correlation between UGT1A1 gene polymorphisms and toxicity and efficacy of irino-tecan(CPT-11) based regimen in the patients with ED-SCLC. Methods: The analysis of UGT1A1?28 and UGT1A1?6 gene poly-morphisms was performed in 67 patients with ED-SCLC admitted in our hospital from June 2011 to January 2013. The 67 cases with ED-SCLC treated with irinotecan(CPT-11) based regimen were enrolled to observe the adverse events and efficacy during the chemo-therapy, including objective responserate rate ( ORR) , progression free survival ( PFS) and overall survival ( OS) . The incidence of different genotypes was compared. Results:The distribution of UGT1A1 genotypes in the 67 patients was follows:UGT1A1?28 wild-type (WT) genotype TA6/6 (56, 83. 6%), heterozygous genotype TA6/7 (11, 16. 4%);UGT1A1?6 wild-type (WT) genotype G/G (45,67. 2%), heterozygous genotype G/A (22,32. 8%). No significant difference of PFS and OS was observed between the differ-ent genotypes. The incidence of grade 3 and 4 delayed diarrhea and neutropenia in the patients carrying UGT1A1?6 G/A was higher than that in those with WT genotype (36. 4% vs. 6. 6%, P<0. 05;27. 2% vs. 4. 4%, P<0. 05, respectively). The incidence of grade 3 and 4 thrombocytopenia in the patients carrying UGT1A1?28 TA6/7 was higher than that in those with WT genotype (27. 2%vs. 1. 8%, P<0. 05). The patients simultaneously carrying UGT1A1?28 TA6/7 and UGT1A1?6 G/A were prone to suffering 3 and 4 delayed diarrhea and neutropenia. Conclusion: UGT1A1 polymorphisms may predict the adverse events of CPT-11 in ED-SCLC, while can not predict the efficacy of CPT-11.

0.05).Conclusions The patients with sepsis lasting more than 7 days had high mortality (50%). While percentage of CD14 and CD14MFI of peripheral blood are increased,the total scores of SOFA and numbers of MOF are decreased.The improvement of monocytes function indicates good prognosis. The changes of expression of ICAM-1,serum TNF-? and IL-10 can not reflect prognosis in septic patients.

Objective To investigate the effect of dual antiplatelet drugs on the intestinal damage in rats. Meth-ods Eighty SD rats were randomly allocated into four groups:control group (normal saline, n=20), aspirin group (10.41 mg/kg, n=20), clopidogrel group (7.81 mg/kg, n=20) and clopidogrel combined aspirin group (n=20). Each group was given intra-gastric administration of drugs once per day for 14 days. All rats received operation after the final intragastric administration. The intestinal injury was observed. The jejunal fluid was taken for bacterial culture. The intestinal permeability was detected by ethidium bromide (EB) method. The small intestinal mucosal injury was estimated by Chiu method. Results The differ-ent degrees of small intestinal mucosal injury were found in four groups. The scores of pathological lesions were significantly higher in aspirin group, clopidogrel group and clopidogrel combined aspirin group than those of control group (P<0.05). The dual antiplatelet group showed the highest score (3.450±1.356). The small intestinal permeability was significantly increased in experiment groups compared with that of control group (54.012±3.513μg/g, P<0.05). There was a significantly higher small intestinal permeability in dual antiplatelet group than that of aspirin group and clopidogrel group (μg/g:130.533 ± 29.631 vs 90.965±3.765 vs 66.800±4.853, P<0.001). The total jejunal bacteria was significantly increased in dual antiplate-let group than that of control group (CFU/mL:61924.805±1751.159 vs 18154.280±1153.376, P<0.001). The ratio of entero-bacterium and enterococcus was significantly decreased in dual antiplatelet group compared with that of control group (0.220±0.089 vs 1.007±0.148, P<0.001). Conclusion The routine dose of dual antiplatelet drug aggravates the small intes-tinal injury in rats compared with that of single drug. The manifestations of intestinal mucosal injury include increased intes-tinal bacteria, dysbacteriosis, and increased small intestinal permeability.

Objective To investigate the clinical features of non-steroidal anti-inflammatory drugs (NSAIDs) caused gastrointestinal bleeding in the elderly.Methods We performed a retrospective analysis ofNSAIDs caused gastrointestinal bleeding with 308 cases admitted to Department of Gastroenterology,The Second Hospital of Tianjin Medical University.Patients were divided into elderly group(≥65 years,n =208) and young group (＜ 60 years,n =100) to make a comparative analysis of two group differences in clinical characteristics.Results The NSAIDs in the elderly taking were mainly Aspirin (55.8 ％ (116/208)),which was significantly more frequent than that of young group (37.0％ (37/100),x2 =9.517,P ＜ 0.05).There was no significant difference on the blood routine and coagulation between the two groups (P ＞ 0.05).The recent bleeding rate of the elderly group (21.2％ (44/208)) was lower than the young group (63.0％ (63/100))(x2 =52.161,P ＜0.05).The two groups had no significant difference on the history of uleer and Hp infection (P ＞ 0.05).Conclusion The clinical characteristics of NSAIDs caused gastrointestinal bleeding on the elderly were different with young or middle-aged.This infers that elderly patients need individualized treatment.
