Objective To evaluate early diagnositic value of thyroid transcription factor-1(TTF-1) for patients with lung cancer.Method Ninety-nine lung cancer tissue samples and 21 non-neoplastic lung tissue samples were collected from surgical resections.TTF-1 expressions in the above samples were assessed by micro array combined with immunohisto-chemistry assay.According to percentage of reactive cells,tissue immunoreactivity for TTF-1 were categorized into 3 groups :negative(

Objective To observe the effects of hepatocyte-like cells differentiated from human umbilical cord mesenchymal stem cells (HuMSCs) on the liver function of the rats with liver cirrhosis.Methods Carbon tetrachloride was used to prepare rat model of liver cirrhosis.Then the rats in the experimental group received portal vein injection of 1 ml differentiated hepatocyte-like cells (1 × 107) ; the mesenchymal stem cell (MSC) group was injected with the same volume and number of MSCs; the model group was injected with the same volume of saline (NS) ; the normal rats were treated as control group.After transplantation,the rat angular vein blood and liver tissue were obtained for testing.Results One week after transplantation,compared with the model group,levels of serum alanine aminotransferase (ALT),aspartate aminotransferase (AST) and total bilirubin (TBil) in the experimental group significantly decreased (P ＜0.05),while the albumin (Alb) level increased significantly (P ＜0.05).Compared with the MSC group,the level of Alb in the experimental group also significantly increased (P ＜ 0.05),but there were no differences between the two groups of ALT,AST and TBil.4 weeks after transplantation,compared with the model group,levels of serum ALT,AST and TBil in the experimental group also significantly decreased (P ＜ 0.05),while Alb level increased significantly (P ＜ 0.05).Compared with the MSC group,the differences of the levels of Alb,ALT,AST and TBil were all statistically significant (P ＜ 0.05).Real-time PCR test results showed that the expressions of four liver-related genes of the MSC group and experimental group significantly increased comparing with the model group (P ＜ 0.05).And the experimental group showed higher expression level comparing with the MSC group (P ＜ 0.05).Conclusion The differentiated hepatocyte-like cells could improve hepatic function of patients with liver cirrhosis to a certain degree and showed greater advantage than MSC.

Objective　To analyze the advantages of intracrani al hematoma smash puncture (IHSP) in the treatment of cranial hemorrhage for the elderly. Methods　A total of 104 cases of cerebral hemorrhage a dmitted in the recent 3 years were collected and divided into 4 grou ps, i.e . group A, elderly with IHSP treatment (n=36), group B, elderly with regular medical treatment (n=33), group C, non-elderly with IHSP treatment (n= 21) and group D, non-elderly with routine therapy (n=14). The clinical and follow-up outcomes were studied and analyzed. Results　There w as significant difference in rehemorrhage rate after puncture between grou p A (0/36) and group C (2/21). Significant difference was found in early mortali ty rate in group A (16.67%) and group B (39.40%). The rate of activity of daily living (ADL) 1-2 was significantly higher in group A (58.62%) than group B (5.88 %)(P<0.005) and that of ADL 4-5 was obvious lower in group A (13.79%) than g roup B (47.06%)(P<0.025). Conclusion　Intracranial hematoma smash hemorrage is safe and efficient in the treatment of elderly cerebr al hemorrhage, especially in reducing the disability rate.

We retrospectively reviewed the clinical data of 826 cases with vitiligo treated in Beijing Hospital from 1998 to 2008. Most of patients present vitiligo in early age;20. 6% patients had positive family history. There were 44. 12 %, 41.18% and 10. 00 % of patients with vitiligo in their first, second and third degree relatives, respectively. Patients with family history had an earlier onset than those without a family history ( t = 1.97, P < 0. 05 ). Vitiligo vulgaris was found in 91.40 % patients. The most common affected site was head and face (31.5%) ;8. 1% of the patients was associated with other autoimmune diseases, including thyroid diseases, diabetes. There were more females than males in patients aged below 14. The child patients were more likely to present with Koebner' sign and halo nevus than the elder ones (P<0.05).

Objective:To establish the fingerprints of Rhizoma Atractylodis macrocephalae from different origins with high performance liquid chromatography(HPLC)technology,which was furthermore applied in the quality comparison of plant resource.Methods:In this method,C1 8column(4.6mm?250 mm)was used with the mobile phase containing acetonitrile-water for gradient elution,acetonitrile(A):0-15min,75%;15-20min,75%-95%;20-35min,95%;35-40min,95%-75%;40-50min,75%,flow rate 1 mL/min and wave length 220nm.Results:The HPLC fingerprints of Rhizoma Atractylodis macrocephalae from different origins were established and the correlated coefficients of each were calculated.9 common peaks were determined in HPLC chromatogram,three of them were identified as atractylenolideⅢ,Ⅰand atractylon respectively.Conclusion:The method was simple,reproducible and can be used as plant resource selection and quality control of Rhizoma Atractylodis macrocephalae.

Objective To determine the effectiveness and safety of antiplatelet and anticoagulant agents in the treatment of extracranial internal carotid artery dissection (eICAD). Methods Antiplatelet and anticoagulant agents were adopted to treat two cases of eICAD in our hospital. The clinical data were retrospectively analyzed and the medical literatures concerning eICAD, which were obtained from Pubmed database, were reviewed. Results Most researches advocated the empirical use of antiplatelet and anticoagulant agents in eICAD. About 30% of occluded eICAD could be reopened in 8 days and about 60% - 80% in 3 months after the onset of the disease. During the period of treatment, the rate of ischemic stroke recurrence, disability or death was 8.3%-14.3% in anticoagulant group, while it was 7% - 23.7% in antiplatelet group. Conclusion Antiplatelet agents can be used in patients with eICAD who are contraindicated to anticoagulants. Anticoagulants should be used as early as possible in patients who are not contraindicated to anticoagulants.

Objective To evaluate the role of Akt and nuclear factor (NF)-κB pathway in the development of chemoresistance in gastric cancer and the relation between Akt and NF-κB.Methods SGC-7901 cells were exposed to chemotherapeutic drugs (doxorubicin and etoposide ) or chemotherapeutic drugs combined with Wortmannin or MG-132.The cell growth was detected using MTT method.The apoptosis of SGC-7901 cells was measured by TUNEL and Annexin V/PI methods.The protein level of NF-κB was analyzed by immunocytochemical staining.Electrophoretic mobility shift assay (EMSA) was used to confirm the increased nuclear translocation of NF-κB/P65.chemotherapeutic drugs could obviously inhibit the growth of SGC-7901 cells in time-dose-dependent manner.Pretreatment of SGC-7901 cells with Wortmannin or MG-132 could promote this inhibitory κB in a dose-dependent manner.Wortmannin or MG-132 pretreatment could enhance the apoptosis of NF-κB was found in SGC-7901 cells stimulated with Wortmannin,but no activation of Akt was noted in those treated with MG-132.Conclusions The chemotherapeutic drugs can both induce apoptosis and activate Akt and NF-κB in SGC-7901 cells.The efficacy of chemotherapeutic drugs can be increased via inhibiting activation of Akt or NF-κB.

It is to difficult to diagnose and treat hepatobiliary surgical diseases since its diverse clinical manifestations,which increases the difficulty of clinical internship.Taking clinical cases as teaching material,case-based learning was combined with teaching theme and was conducted by means of discussion and question and answer between teachers and students.Students can know about concepts or theories related to teaching theme.Case-based learning in internship can consolidate basic knowledge of hepatobiliary surgery,cultivate clinical scientific thinking and is helpful in analyzing and resolving problems of hepatobiliary surgical diseases.

Remarkable progress has been achieved in the transplantation of mesenchymal stem cells (MSCs)for the treatment of liver injury and hepatic failure.However,there are obstacles such as low engraftment capacity,tumorigenesis,and a fibrogenic potential that all hamper the use of MSCs in clinical trials.Therefore,it is worthwhile to talk about the alternatives that will increase the safety and efficacy of MSCs therapy.To date,applications of MSCs-derived hepatocytes,genetically modified MSCs,or MSC-conditioned medium for promoting liver regeneration have shown encouraging results.This review summarizes the current applications of MSCs in the study of hepatic regeneration.
