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.

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 explore the diagnosis and Fogarty catheter embolectomy operation management of acute arterial embolism in the extremities.Methods The clinical data of 87 cases of acute arterial embolism in the extremities treated by Fogarty catheter was ana- lyzed retrospectively,Results All cases were diagnosed through asking patient history and symptom,physical examination and the check of color Doppler while the results were proved by operation.No one case received vasography.After operation,78 cases blood stream of limb had been resumed and cure rate of 87.6% was achieved while 4 cases improved(4.5%),and no occurrence of ischemic necrosis and amputated ex- tremity.5 cases(5.6%)received amputation at the relative level and there were 2 cases(2.3%)of perioperative death.Those cases who re- ceived operations within 48 hours from the time of morbidity achieved cure rate of 100%,while those cases more than 48 hours achieved cure rate of 47.6%,improvement rate of 19.0%,amputation rate of 23.8% and mortality of 9.6%.Conclusion First,Ultrasound Doppler exami- nation should be taken for avoidance of misdiagnosis when acute extremity arterial embolism is suspected.Second,The key Intraarterial embo- lectomy using Fogarty catheter is an effective method for the treatment of acute arterial embolism in the extremities,is significant in application,Third,as soon as the diagnosis is established,embolectomy with Forgarty catheter must be carried out to avoid clot extension and necrosis of the extremity.Satisfactory therapeutic efficacy can be got,if the patient receive operation within 48 hours from onset.

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

AIM:To observe the effects of adiponectin on injury of the 3-4 d SD rat cardiomyocytes induced by the intervention of H2O2.METHODS:Primary cardiomyocytes were obtained from neonatal rat and were cultured by enzymatic digestion methods.The molecular marker was observed by ?-actin immunocytochemistry.Primary cultured 3-4 d cells were used in experiment,and the injury model was established by H2O2,and adiponectin and Ara-A were used for pre-treatment before cell culture.The morphological change of cardiomyocytes was observed under electron microscope.The contents of LDH,MDA and the activity of SOD were measured.The apoptosis of cardiomyocytes was detected by agarose gel electrophoresis and Annexin V/PI staining with flow cytometry.RESULTS:Adiponectin pretreatment significantly decreased the release of LDH(P
