1.Establishment and characterization of SAC clone system from a mouse SRS ascitic tumour
Chinese Journal of Pathophysiology 1986;0(02):-
A clone system designated SAC was established from a SRS-82 mouse ascitic turnout cell line by using limited dilution method. Clones SAC-ⅡB_2, SAC-ⅡB_3 of this system were found to be different in their morphology, growth pattern, karyotypes and tumorigenicity from their parent cell line. Both the two clones and their parent cell line were X-C assay positive, and type A and type C virus particles were found in the cytoplasm and cell surface of these cells electronmicroscopically. Cell surface markers(ALS, Thy, SmIg G) of these two clones and their parent cell line were investigated by ABC immunohistochemical method and immunofluorescent staining technique, the results of which indicate that all of them belong to T cell origin.

Journal of China Medical University 2016;45(7):591-595,600
Objective To investigate the effects of combined treatment of suberoylanilide hydroxamic acid(SAHA)and TNF?related apoptosis inducing ligand(TRAIL)on proliferation and morphology change of triple?negative breast cancer cell MDA?MB?231. Methods The effects of combination treatment of SAHA and TRAIL on proliferation and morphology change of MDA?MB?231 cells were monitored by RTCA. Morphology changes of MDA?MB?231 cells by different treatment factors were observed through time?lapse live cell imaging acquisition. Results Real?time cell proliferation assays showed that a synergistic effect were found when MDA?MB?231 cells were treated with combination of SAHA and TRAIL , and reached the best effect with 5μmol/L SAHA and 50 ng/mL TRAIL. The results of time?lapse live cell imaging acquisition showed that the growth inhibition of MDA?MB?231 cells with combined treatment of SAHA and TRAIL were more obvious than that with treatment of SAHA or TRAIL alone. Conclusion The combined treatment of SAHA and TRAIL induces a synergistic effect on growth inhibition in triple?negative breast cancer cell line MDA?MB?231.

4.Establishing better biological models to understand occlusion.I:TM joint anatomic relationships
Journal of Practical Stomatology 2015;(4):560-576
Belief in and rejection of a relationship of occlusion and temporomandibular joint (TMJ)condyle-fossa position with normal and abnormal function are still contentious issues.Clinical opinions can be strong,but support in most published data (mostly univariate)is problematic.Distribution overlap,low sensitivity and specificity are a common basis to reject any useful prediction value.Notwithstanding,a relationship of form with function is a basic tenet of biology.These are multifactor problems,but the questions mostly have not been analysed as such.This review moves the question forward by focusing on TMjoint anatomic organisation as the multifactor system it is expected to be in a closed system like a synovial joint.Multifactor analysis allows the data to speak for itself and reduces bias.Classification tree analysis revealed useful prediction values and usable clinical models which are illustrated,backed up by stepwise logistic regression.Explained vari-ance,R2 ,predicting normals from pooled TMJ patients was 32.6%,sensitivity 67.9%,specificity 85.7%;37% versus disc displacement with reduction;and 28.8% versus disc displacement without reduction.Significant osseous organisational differences between TMjoints with clicking and locking suggest that this is not necessarily a single disease continuum.However,a subset of joints with clicking contained char-acteristics of joints with locking that might contribute to symptom progression versus resistance.Moderately strong models confirm there is a relationship between TMJ osseous organisation and function,but it should not be overstated.More than one model of normals and of TMde-rangement organisation is revealed.The implications to clinical decision-making are discussed.
5.Updates on the research of genetics and epigenetics of pancreatic neuroendocrine tumors
Chinese Journal of Digestive Surgery 2014;13(10):822-825
Mounting evidences suggest that the ATRX (α-thalassaemia/mental retardation syndrome X-linked) and DAXX (death-domain associated protein) which encode 2 subunits of a chromatin remodelling complex required for H3.3 incorporation at pericentric heterochromatin and telomeres,and multiple endocrine neoplasia type 1 (MEN-1) genes are significantly mutated in most patients with pancreatic neuroendocrine tumors (pNETs),as are genes encoding key molecules of the mammalian target of rapamycin (mTOR) signaling pathway.These mutated genes promote deregulation of epigenetic processes such as chromatin remodeling,histone modification and activation of alternative lengthening of telomeres,and thus combined alteration of these genes may contribute to drive tumorigenesis and metastasis of pNETs which are characterized by complex patterns of phenotypes.These findings may have great significance in the diagnosis and treatment of pNETs and predicting the prognosis,as well as providing clinical implications for targeted cancer therapy.
6.Small cell carcinoma of urinary bladder (report of 6 cases)
Chinese Journal of Urology 2000;0(12):-
Objective To improve the understanding of small cell carcinoma of the urinary bladder. Methods The pathological and clinical data of 6 small cell carcinoma cases (4 men and 6 women, mean age of 51 years) were analyzed.Of them 2 cases had components of transitional cell carcinoma or adenocarcinoma.Two cases underwent partial cystectomy,and 4 cases,cystectomy.After operation,5 of them underwent 2~6 courses of chemotherapy. Results All the 6 cases were followed-up for 12~60 months,and they all died of tumor relapse.Their average survival time was 28 months. Conclusions Small cell carcinoma of urinary bladder accounts for 0.44% of the primary malignant tumor of urinary bladder.It has high malignancy and easily metastasizes to lymph nodes,liver and bones,thus the prognosis is bad.Radical cystectomy in combination with systemic chemotherapy has better efficacy.

9.Neuroprotective mechanisms of histone deacetylase inhibitors in ischemic stroke
International Journal of Cerebrovascular Diseases 2010;18(5):358-362
Histone deacetylases (HDACs) catalyze the deacetylation of histone and nonhistone proteins. They play important roles in regulating chromatin remodeling and gene transcription,and that aberrant chromatin remodeling and transcriptional dysregulation are associated with many neurodegenerative diseases. Preclinical studies have suggested that histone deacetylases inhibitors (HDACIs) can target diverse pathophysiologies of ischemic stroke,not only reduce neuronal damage and infarct volume,but also promote the neuronal plasticity and functional recovery after ischemia. This article mainly reviews the neuroprotective mechanisms of HDACIs in ischemic stroke.
10.Clinical application of pancreatic amylase and lipase in acute pancreatitis
International Journal of Laboratory Medicine 2008;29(11):980-982
Objective To investigate the clinical value of pancreatic amylase (P-AMY) in acute pancreatitis, and perform methodical evaluation on total amylase (α-AMY), P-AMY and lipase.Methods 126 cases of patients with acute pancreatitis, 105 cases of disease controls and 95 healthy controls were involced in the investigation. Hitachi7600 automatic biochemical analyzer was applying to measuring α-AMY, P-AMY and lipase. The upper limit of the reference range of the total amylase, pancreatic amylase and lipase was 216 U/L, 115 U/L and 200 U/L respectively in our laboratory.Results The sensitivity of total amylase, pancreatic amylase, and lipase for the diagnosis of acute pancreatitis was 73.1%, 88.5% and 92.3% respectively;and while the specificity was 70.5%、81.9% and 82.9% respectively. The diagnostic accuracy, determined as the area under the curve, was 0.795 for total amylase, 0.868 for pancreatic amylase, and 0.886 for lipase. There was a significant difference between the total amylase and pancreatic amylase (P=0.045), but no significant difference was found between the pancreatic amylase and lipase (P=0.613) by ROC curve.Conclusion Pancreatic amylase has a higher sensitivity, specificity and diagnostic accuracy than α-AMY in acute pancreatitis, and shows a similar diagnostic performance as lipase. Therefore, P-AMY and lipase should be measured in combination in the diagnosis of acute pancreatitis.
