Practical Oncology Journal 2017;31(3):205-210
Objective The relationship between the clinicopathological features and the prognosis of breast cancer patients was evaluated by the expression of EPB41L4A-AS2 in breast cancer tissues.Methods The relationship between the expression of EPB41L4A-AS2 and the clinical features of breast cancer was evaluated by using the genome meta analysis,TCGA and Gene Expression Library(GEO) datasets.The correlation between EPB41L4A-AS2 and apoptotic pathway was verified by Western blotting.Results The results from Meta -analysis,TCGA and GEO datasets showed that EPB41L4A-AS2 was low in breast cancer tissues and was positively correlated with poor clinical and pathological features.EPB41L4A-AS2 was confirmed an association with the classical apoptosis pathway in breast cancer cell lines.In the meta-analysis of GEO,we found the high expression of EPB41L4A-AS2 with good prognosis.Conclusion EPB41L4A-AS2 inhibits tumor formation and has a high value in clinical prognosis of breast cancer.
2.Diagnosis and management of splenic cysts
International Journal of Surgery 2008;35(6):407-409
Splenic cyst is clinically rare.It can be classified as either true or false.Ultrasound,CT and MRI scan are helpful in diagnosing splenic cyst.Indication for a treatment depends mainly on clinical symptoms and diameter of the cyst.Now,there is a more conservative attitude on splenic surgery and the patient should be offered laparoscopic approach.Both nonoperatively treated patients and surgically treated patients should be given ultrasound examination regularly,in order to check the cyst size and exclude reappearance.
3.The changes and the significance of salivary levels of immunoglobulin A, alpha-amylases and acetylcholinesterase in patients with Parkinson disease
Chinese Journal of Geriatrics 2016;35(8):811-814
Objective To detect the salivary levels of IgA,alpha-amylase and acetylcholinesterase (AChE) and saliva flow rates of IgA in normal controls versus Parkinson disease (PD) patients,and to analyze the correlation of these salivary biochemical indexes with disease duration,H&Y rating scale,SCOPA-AUT score,sialorrhea score,dry mouth score and the use of levodopa.Methods Thirty-eight PD patients including twenty-two patients treated with levodopa,and twenty-one normal controls were selected in our study.About 3 ml saliva was collected from each subject.Salivary IgA was detected by immunoturbidimetry.Alpha-amylase and AChE were tested by enzymatic colorimetry.The protein concentration was analyzed by BCA kit to normalize ACHE.The salivary flow rate and IgA flow rate were also calculated.Results Salivary flow rate (ml/min) was (0.39±0.22) in normal controls,and (0.35±0.28) in PD groups;the level of IgA (mg/L) was (148.3±86.1) in normal controls,and (183.7±126.3) in PD groups;IgA flow rate (μg/min) was (47.8±25.9) in normal controls,and (46.9±27.1) in PD groups;the level of alpha-amylase (U/L) was (1.63 ± 1.21) × 105 in normal control,and (1.35 ± 9.87) × 105 U/L in PD group;and the level of AChE (U/mg) was (0.12±0.08) in normal controls,and (0.09±0.05) in PD group.No statistically significant differences in above indexes were found between PD group and controls.There were negative correlations between salivary flow rate and dry mouth score (r =-0.445,P =0.005) and between alpha-amylase concentration and sialorrhea score (r=-0.327,P=0.045).The positive associations were found between IgA concentration and the SCOPA-AUT score (r =0.438,P =0.006),and between IgA flow rate and sialorrhea score (r =0.411,P =0.01).Conclusions Salivary flow rate and level of alpha-amylases tend to be decreased in PD patients,while IgA concentration has an upward tendency.Salivary alpha-amylases concentration and IgA flow rate are correlated with the symptom of sialorrhea,while IgA concentration correlates with the degree of autonomic symptoms.These measurements can be used as indexes for evaluating the lesions of the autonomic nervous system.
