International Journal of Pediatrics 2014;(5):559-560,564
Objective To evaluate the clinical significance of myocardial enzymes and high sensitive C-reactive protein( hs-CRP) in children with herpangina. Methods A total of 80 children with herpangina( obser-vation group,n=80),at the same time,50 healthy children as control group(n=50)were assigned for the detec-tion of myocardial enzymes(AST,LDH,CK,CK-MB)and hs-CRP. Results The elevated CRP levels were found in 45(56. 25%)patients of observation group and 2(4%)patients of the control group,showing statistical significance(χ2 =31. 55,P<0. 01). Abnormal myocardial enzyme levels were observed in 59(73. 75%)cases, which included AST 51. 6%, CK 40. 1%, CK-MB 21. 4%, LDH 72. 2%. Abnormal myocardial enzyme levels were observed in 6(12%) cases of control group,which included AST l6%,CK 10%,CK-MB 4% and LDH 12%. The significant differences were observed between the two groups ( P<0. 01 ) . Conclusion Herpangina children may have different degrees of myocardial damage. Myocardial enzymes and hs-CRP are useful indicators for myocardial injury which may effectively provide reference for clinical diagnosis and treatment.

Objective To investigate the incidence of anxiety in patients with breast cancer,and further explore the surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI) technology' s clinical value in the diagnosis of anxiety.Methods 121 breast cancer patients were selected as research objects by using convenience sampling method.Self-rating anxiety scale (SAS) was used to evaluate the anxiety on the first day of admission and SELDI was used on the next day to detect the serum from patients' fasting venous blood sample got in the morning after their consent,then anxiety-related protein fingerprints spectrums were selected.The SAS score and SELDI result were finally compared and analyzed.Results SAS score in 121 patients was 53.45±9.78,anxiety occurred in 63 cases (52.07 %).Established the diagnostic model between 15 000+H and 16 800+H protein fingerprints abundance ≥5 %,that was to say,abundance ≥5 % was judged as positive,otherwise negative.On this basis,patients can accurately be distinguished between anxious group and non-anxious group.Correct rate (total coincidence rate) was 91.74 %,specificity and sensitivity respectively were 89.66 % (52/58) and 93.65 % (59/63),the positive predictive value was 90.77 % (59/65),and negative predictive value was 92.86 % (52/56).Conclusions Breast cancer patients have a high incidence of anxiety.SELDI technology has showed high sensitivity and specificity in anxiety detecting.As an objective assessment tool,it could have better prospects for clinical use.

ObjectiveTo observe the effects of free fatty aids (FFAs) on the apoptosis and migration of human breast cancer cells ( MDA-MB-231 ).MethodsBreast cancer cells were exposed to oleic acid (OA) and palmitic acid (PA) with different concentrations (50,200,and 500 umol/L).Quantity RT-PCR was conducted to detect mRNA expression of PTEN,and Western blot to detect protein expression of PTEN and Bcl-2.Cell apoptosis was measured with TUNEL method,and migration measured with transwell method.ResultsThe mRNA and protein expressions of PTEN in MDA-MB-231 cells were down-regulated after OA stimulation,but up-regulated after PA stimulation ( all P < 0.05 ).The protein expression of Bcl-2 increased after OA stimulation and decreased after PA stimulation ( both P < 0.05 ).PA increased the apoptosis,and both OA and PA enhanced the invasion of MDA-MB-231 cells.ConclusionsPA may promote apoptosis of MDA-MB-231 cells through changing the expression of the tumor suppressor PTEN,but also increases the invasion of the cancer cells.The invasion of cancer cells could be enhanced by OA stimulation as well.

Objective To evaluate the value of multiplanar reconstruction (MPR) of spiral CT in diagnosing and staging of cervical cancer .Methods SCT scan with a 3~5 mm collimation thickness and MPR in 1.5~2.5 mm reconstruction interval were performed in 20 patients with cervical cancer , confirmed by biopsy pathology. Results The sagittal imaging could show entirely the growing character of a carcinomal mass;the coronal and transverse imagings showed clearly parametrial invasion and pelvic lymph node metastases. Conclusion MPR images in the pelvic could show entirely the character of growing and invasion of a carcinomal mass. It is an important value in dignosing and staging of cervical cancer.
