Objective To explore the relationships among implicit self-esteem,explicit self-esteem and alexithymia.Methods According to the scores of Toronto Alexithymia Scale(TAS-20),82 tests were divided into the alexithymia group and the control group,which were assessed with Rosenberg Self-Esteem Scale(SES) and Implicit Association Test (IAT).Results The level of explicit self-esteem in the alexithymia group was significantly lower than that of the control group((28.57 ±4.57 vs 32.44 ±2.71)),there was significant differences between two groups(P＜ 0.01).Each factor of the alexithymia (as difficulty describing feelings,difficulty identifying feelings and externally oriented thinking) had significantly negative correlation with explicit self-esteem (r =-0.572,-0.52,-0.56,-0.378,P ＜ 0.01),and the alexithymia was positively correlated with the degree of separation in implicit and explicit self-esteem (r =0.421) (P ＜ 0.05).Conclusion The alexithymia group has defects in the process of controlling emotional; Alexithymia as a kind of psychological traits may be influence consistency of implicit and explicit self-esteem.

A total of 306 Malaysian university students and staff were surveyed to ascertain the physical and emotional effects of the polluted haze on them. All subjects completed self-reported questionnaires. Analysis of the results indicated that the majority of subjects reduced their outdoor activities and sports, and also reported an increase in emotional and physical health problems. The results indicated that there was a general increase in emotional problems such as feeling depressed, lacking in energy, not feeling like doing anything, feeling anxious and afraid, difficulty sleeping, feeling agitated and irritable, and having no appetite. There was also an increase in physical symptoms such as itchy or red eyes, itchy or running nose, dry throat/cough, headaches, nausea, and fever. This study indicated that emotional and behavioural problems are just as common during the haze, when compared with physical health problems. The study also suggests that there are a broad range of problems which health care and human resource departments need to be aware of and take precautions to minimize during a haze.

Objective To investigate the risk factors of severe intrahepatic cholestasis during early period after liver transplantation.Methods The clinical data of 225 patients who received orthotopic liver transplantation at the Nanfang Hospital of Southern Medical University from August 2004 to February 2011 were retrospectively analyzed.All patients were divided into positive group (60 patients with intrahepatic cholestasis) and negative group (165 patients without intrahepatic cholestasis).Preoperative,intraoperative and postoperative factors of the 2 groups were compared via t test,chi-square test,Wilcoxon test or Logistic regression analysis.Results The proportion of patients with hepatic cirrhosis,hepatic encephalopathy integral,ascites integral,international normalized ratio,and the levels of prothrombin time (PT),total bilirubin (TBil),aspartate aminotransferase of the positive group before operation were significantly higher than those in the negative group (x2 =6.09,Z =2.22,2.60,2.46,2.84,4.81,3.42,P ＜ 0.05),while the levels of albumin,Na +,K +,hemoglobin,platelet (PLT) of the positive group in the operation were significantly higher than those in the negative group (t =2.10,4.97,Z =2.49,t =3.51,Z =3.66,P ＜ 0.05).The ratio of compatible blood type of the donors and recipients,ratio of fatty liver graft,cold ischemia time,relative warm ischemia time,intraoperative blood loss,intraoperative transfusion of red blood cells,PLT,and cryoprecipitate of the positive group after the operation were significantly higher than those in the negative group (x2 =4.29,13.11,Z =2.45,2.61,3.75,3.20,2.89,3.95,P ＜0.05).The incidences of acute rejection,hepatic artery embolism,pulmonary infection,bacteraemia,fungal infection and cytomegalovirus (CMV) infection were significantly higher than those in the negative group (x2 =9.87,4.91,8.21,6.29,3.92,9.26,P ＜0.05).The results of multivariate analysis revealed that preoperative level of TBil ＞ 51.3 μmol/L,fatty of the liver graft,intraoperative transfusion of cryoprecipitate,postoperative acute rejection,hepatic artery embolism,postoperative pulmonary infection,bacteraemia,CMV infection were independent risk factors of severe inrahepatic cholestasis (OR =15.82,7.99,2.88,3.03,53.20,3.34,4.11,3.22,P ＜ 0.05).The incidence of severe intrahepatic cholestasis was significantly lower in patients with higher level of PLT and longer PT (OR =0.33,0.25,P ＜ 0.05).The mortality rates of the positive group and negative group at 6 months after the operation were 41.7％ (25/60) and 19.4％ (32/165),and the mortality rate of the positive group was significantly higher (x2 =11.54,P ＜ 0.05).Conclusion Correction of poor clinical status before liver transplantation,reinforcement of infection control and anti-rejection may reduce the incidences of complications and decrease the associated early mortality.

Objective To investigate the prognostic relevant factors of hepatocellular carcinoma (HCC) in recipients following liver transplantation (LT).Methods The clinical data of 147 cases of HCC undergoing LT between Aug. 2004 and Feb. 2011 in Nanfang Hospital were studied retrospectively.Those of significance in 14 relevant factors involving gender,age,blood-type,CTP,model of end-stage liver disease (MELD),alpha-fetoprotein (AFP),tumor number,cumulative diameter of tumor,tumor occupying proportion of the liver,bilobar involvement,envelope invasion,macrovascular invasion,and microvascular invasion (MVI),HCC histology differentiation,which were based on univariate analysis with Log-Rank,were analyzed by means of Multivariate Cox proportional hazard regression model to screen out independently relevant ones.Results 143 cases were followed up.The follow-up duration ranged from 6 to 84 months.The 1- and 3-year cumulative survival rate was 75.2％ and 54.7％ respectively.The tumor free 1- and 3-year cumulative survival rate was 70％ and 59％ respectively.Univariate ananlysis revealed that age,AFP,tumor number,cumulative diameter of tumor,tumor occupying proportion of the liver,bilobar involvement,envelope invasion,macrovascular invasion,and MVI had significant difference, In a Cox model,MVI,macrovascular invasion and AFP≥ 400 μg/L were independent prognostic factors.Conclusion MVI,macrovascular invasion and AFP are the main prognostic risk fators.Intervention and non-tumor technique should be performed preoperatively and intraoperatively,respectively.

BACKGROUND: Recent data suggested that Notch signal pathway plays important regulatory effects in peripheral transplantation immunological response, promotes differentiation of regulatory T cells, induces antigen specific immune tolerance. We proposed that Notch/Notch ligand may play important roles in MHC/TCR interface.OBJECTIVE: To construct the eukaryotic expression vector of rat Deltai gene (Notch ligand), and to examine its expression in dendritic cells.METHODS: The complete encoding cDNA of rat-Delta1 was isolated from bone marrow cells by reverse transcription-polymerase chain reaction (RT-PCR) and this gene was recombined into pcDNA3.1(+) plasmid vector.pcDNA3.1/Delta1 plasmid was transfected into rat dendritic cells with lipofectamine gene transfection method.RESULTS AND CONCLUSION: Double enzyme digestion detection demonstrated that Delta 1 had been successfully constructed in Hindilll and xbal of pcDNA3.1. A positive clone pcDNA3.1/Delta1 was delivered to Shanghai Sangon Biological Engineering Technology & Services Co., Ltd. for sequencing. Sequencing results were identical to Delta1 gene sequence in Genebank, with correct reading frame. The Delta 1 gene-transfected dendritic cells showed similar morphology as their parent cells. Western blotting assay detected that Delta 1 expression was significantly increased in cells. The eukaryotic expression vector pcDNA3.1/Delta1 was constructed, and significant increase of Delta 1 expression was detected after transfection.

Objective To investigate the effects and toxic side effects of concurrent radiotherapy and chemotherapy combined with adjuvant chemotherapy in nasopharyngeal carcinoma.Methods 141 patients of nasopharyngeal carcinoma divided into two groups randomly.All patients treated two-dimension exact radiotherapy and concurrent chemotherapy which combined DDP and 5-Fu intravenously for two circles,then experiment group started adjuvant chemotherapy 3 weeks later after above treatment,which intravenous DDP and 5-Fu for other three circles.Results All patients completed concurrent radiotherapy and chemotherapy,63 patients of treatment group completed adjuvant chemotherapy.The mainly toxic side effect was mucositis,leukopenia and low-platelet,and gastrointestinal reaction during therapy,there is no statistical significance in two groups.The regression rate of lymph nodes is 94.4 ％(n=67)and 87.3 ％(n=62)in nasopharynx and neck after 3 month of radiotherapy and concurrent chemotherapy.All patients followed up 3 years.The total survival rate of two groups were 94.3 ％,84.8 ％,78.6 ％ and 90.1％,75.0 ％,62.5 ％ respectly in 1,2 and 3 year,the mean survival period was 36 months and 27 months,and this differece was statistical significance(x2=7.356,P=0.007).The total survival rate of Ⅲ stage patients of two groups were 98.2 ％,92.5 ％,83.7 ％ and 93.0 ％,83.2 ％,68.2 ％ respectly in 1,2 and 3 year,the both mean survival period was 36 months,and this differece was statistical significance(x2=8.081,P=0.005).The total survival rate of Ⅳ stage patients of two groups were 81.3 ％、53.8 ％、42.9 ％ and 78.6 ％、36.4 ％ 、22.3 ％ respectly in 1,2 and 3 year,the meat survival period were 22 month and 14 month respectly,and this differece was statistical significance(x2=3.903,P=0.048).The progression-free survival rate of two groups were 90.0 ％、76.2 ％、68.8 ％,and 81.7 ％、60.3 ％、34.3 ％ respectly in 1,2 and 3 year,the meat progression-free survival period was 30months and 22months,and this differece was statistical significance as well(x2=13.616,P=0.000).Conclusion The therapy of concurrent radiotherapy and chemotherapy combined with adjuvant chemotherapy was obviously increased total survival rate and progression-free survival rate in nasopharyngeal carcinoma,especially to Ⅲ and Ⅳ stage patient of nasopharyngeal carcinoma.But the long period effects still remains unclear.

BACKGROUND:Growth differentiation factor 5 (GDF5) has been shown to play a crucial role in the development of chondrocytes via different regulatory mechanisms.
OBJECTIVE:To explore the effect of GDF5 on the chondrogenic differentiation of adipose-derived stem cel s (ADSCs).
METHODS:ADSCs in passage 4 isolated from Japanese White rabbits were cultured in the medium containing 0 (blank control group), 10, 50, 100, 150 and 200μg/L, respectively. The morphological changes were observed, and the optimal concentration of GDF-5 was screened, and its round coverslips at 1, 2 and 3 weeks of culture were selected to undergo immunocytochemistry, toluidine blue staining and immunofluorescent staining.
RESULTS AND CONCLUSION:The growth of ADSCs was stable in the medium containing 10 and 50μg/L GDF5, while apoptotic cel s appeared after induction with 200μg/L GDF5. In the medium containing 100 and 150μg/L GDF5, some spindle-shaped cel s changed into irregular shape, and became round or oval after 7-10 days of culture. The optimal concentration of GDF5 was 100μg/L. The cel s transfected by 100μg/L GDF5 were positive for type II col agen obviously and with blue-stained nucleus. The transfected cel s were positive for toluidine blue, and metachromatic granules were visible in the cytoplasm. The proteoglycan mRNA expression of the transfected cel s was significantly increased, and reached the highest at 3 weeks. These results suggest that GDF5 promotes the chondrocytic differentiation of ADSCs.
