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 establish the determination method for icariin in Zhuyun Capsules. Methods: The main active component icariin of Herba Epimedii was determined by TLC scanning. Results: This methods was quick, simple, accurate and reproducible. Conclusion: This method can be used as one of quality control standards for Zhuyun Capsules.

Objective To evaluate the criteria for diagnosis of atypical squamous cells(ASC)and its two subtypes: undetermined significance ASC (ASC US) and atypical squamous cells cannot exclude high grade intraepithelial lesion (HSIL, ASC H) defined in 2001 the Bethesda system(TBS) Method One thousand one hundred and eighty six pap smears and liquid based thin layer preparations with diagnosis of atypical squamous cells of undetermined signification (ASCUS) according to TBS 1991 criteria, were re classified by a cytopathologist using TBS 2001 criteria Results The cytologic diagnosis according to TBS 2001 criteria was: negative in 285 cases(24 0 %), ASC US in 627 cases (52 9 %), ASC H in 254 cases(21 4 %), low grade intraepithelial lesion (LISL) in 16 cases(1 3 %), and HISL in 4 cases (0 3 %), respectively Out of 1186 cases, 168 received histological examination Cervical intra epithelial neoplasia (CIN) II III were diagnosed in 18 9 % of patients with ASC H, 5 2% of patients with ASC US, and 14 3% of patients with ASCUS defined by using TBS 1991 criteria, respectively ( P

Objective To investigate the dynamic changes of Trk(tropomyosin receptor kinase) and Akt(protein kinase B), and to explore the neuroprotective role and its mechanism of β-NGF (β-nerve growth factor) after focal cerebral ischemia. Methods A focal cerebral ischemia rat model was made and β-NGF was injected intra abdominally. The phosphorylation of Trk and Akt were tested by immunocytochemistry and Western blot assay. Results Trk receptor was increased obviously in the penumbra area after 8 h of infarction. The level of phosphorylated Trk(p-Trk) was increased after 2 h of infarction, while the level of phosphorylated Akt(p-Akt) had a decrease and then recovered gradually. The level of p Akt in cerebral ischemia group was decreased by 76.5% compared with that in control group after 8 h of infarction(P<0. 01). After the injection of β-NGF, the level of p-Trk was increased by 74.4% after 12 h of infarction(P<0.01), while the level of p-Akt was recovered significantly after 8 h of infarction, and had no statistical difference compared with the control group after 24 h of infarction (P>0.05). Conclusions Ischemia induces the activation and increased expression of Trk receptor, andβ-NGF may play a protective role in cerebral ischemia by increasing the phosphorylation of Trk and regulating the phosphorylation of Akt.

Objective To investigate the pathological findings and diagnosis value of CT and MRI in detec-tion of primary centralnervous system lymphoma (PCNSL)so as to improve diagnostic accuracy of the condition. Methods The results of CT and MRI for 32 patients with PCNSL were analyzed retrospectively,and the results were compared with the finally obtained surgical-pathological examination.Results Of 32 cases,the foci were single in 29 cases and multiple in 4 cases,and there were 41 foci in total.Most foci were located near the surface or middle line of brain.On CT scan appearances,most foci were hyperdensity or slightly hyperdensity masses with the well definite margin,on MRI,it showed low signal of T1 -weighted imaging (T1 WI)and slightly increased non-uniform signal of T2 -weighted imaging (T2 WI).All the foci were equally and markedly enhanced after enhancement.The diagnostic coincident rate of combination diagnosis (93.8%)was significantly higher than that of CT (71.9%)and MRI (75.0%)(χ2 =7.234 6,P=0.003 2;χ2 =6.953 8,P=0.003 7).Conclusion CT,MRI have characteristic mani-festation for PCNSL,and according to the manifestation of CT,MRI,predilection site,mass effect,and combined with pathological examination,which can effectively improve the sensitivity and accuracy of diagnosis.
