Objective To evaluate the factors influencing prognosis and to explore the pathological mechanism in which herpes simplex virus encephalitis(HSE) was one of the severe types of acute viral encephalitis in children and had poor prognosis.Methods Twenty-one children with HSE were diagnosed by the clinical syndrome of focal encephalitis and HSV DNA-PCR positive in cerebrospinal fluid(CSF) from Jan.2012 to Oct.2013,among whom,19 patients were treated with intravenous Acyclovir,30 mg/(kg · d) 48 hours after onset and were followed up for 6 to 24 months.Clinical data were collected including Glasgow Coma Score,the brain magnetic resonance imaging(MRI),and electroencephalography(EEG).All MRI examinations including plain scan and contrast enhancement were carried out at the beginning of admission and 1 month after the onset of symptoms.The clinical outcomes were divided into two levels accoming to the severity of the neurological deficit,then the data were analyzed by using Logistic regression and Fisher's exact probability method.The OR value was calculated.Results Eighteen children survived,of whom 5 cases had no neurological deficit(27.8％),3 cases were left with mild impairment(16.7％),and the above 8 cases were thought to have better outcome.Six cases had moderate impairment (33.3％) and 4 cases had severe impairment(22.2％) and 1 child died,and these 11 cases were thought to have worse outcome.Patients aged between 1 month and 10 years,average (2.03 ± 2.23) years old.The mean GCS score was (9.68 ± 2.65) scores,the GCS of the patients were more than 7except for one death child with 3 scores.The multiple factor analysis showed that EEG,age,GCS and the range and character in MRI were significantly correlative to the prognosis(P ＜ 0.05).The single factor analysis illustrated that age 1-4 years old(OR =30,95％ CI 2.066-366.510,P =0.002),GCS ≤ 10 scores(OR =27.518,95％ C1 2.066-366.510,P =0.004)and the wide necrosis existence involving diffuse white matter or deep nuclei of MRI findings (OR =12,95 ％ CI 1.294-111.323,P =0.017) indicated the worse outcome.Conclusions Age,GCS score,nature and damage degree of MRI lesions are the main important factors affecting the prognosis of children's HSE.HSE in children is apt to involve the cortex such as frontal lobe,parietal lobe even diffuse white matter or deep nuclei,which indicates the poor prognosis.

Objective: To explore the predictive value of high-sensitivity C-reactive protein (hs-CRP) levels in patients with persistent atrial fibrillation (AF) recurrence after radiofrequency catheter ablation (RFCA). Methods: A total of 77 patients of persistent AF as the first diagnosis with initial RFCA in our hospital were studied. The patients were divided into 2 groups: Recurrent group, n=27 and Non recurrent group, n=50. Basic clinical conditions were studied by Cox model analysis to screen the risk factors for AF recurrence, receiver operating characteristic (ROC) curve was conducted to assess the predictive value of hs-CRP level on AF recurrence. Results: AF recurrence was related tothe age (HR=1.126, 95% CI 1.044-1.215, P=0.002), body mass index (HR=1.297, 95% CI 1.077-1.563, P=0.006), hypertension at stage II (HR=4.142, 95% CI 1.047-16.390, P=0.043), hypertension at stage III (HR=8.595, 95%CI 1.913-38.610, P=0.005), left atrial size (HR=1.438, 95% CI 1.212-1.707, P=0.000) and hs-CRP (HR=2.026, 95% CI 1.010-4.061,P=0.047). The area under ROC curve of hs-CRP level was 0.693,P=0.005 with the cut-off point at 0.355 mg/dl. Conclusion: Persistent AF recurrence after RFCA was related to pre-operative inflammatory status; actively control pre-operative condition may reduceAF recurrence, improve prognosis and decrease adverse cardiovascular event in relevant patients.

Objective: To investigate the differences of biochemical markers between the patients with pulmonary hypertension related to left heart disease (PH-LHD) and LHD; to explore the sensitive bio markers which may predict PH in LHD patients. Methods: A total of 355 LHD patients admitted to our hospital from 2014-01 to 2015-05 were enrolled. According to 2009 ESC/ERS guidelines, PH was deifned by pulmonary artery systolic pressure (PASP)>50 mmHg and patients were divided into 2 groups: LHD group,n=224 and PH-LHD group,n=131. The basic information with blood levels of biomarkers was recorded and their accuracy for predicting PH was analyzed. Results: The pathogenesis of LHD included 184 (51.83%) patients of coronary heart disease, 90 (25.35%) of dilated cardiomyopathy and 81 (22.81%) of cardiac valve heart disease. Compared with LHD group, PH-LHD group had increased ratio of NYHA III and IV degree (89.31% vs 45.54%), decreased LVEF [42.0 (33.0, 59.0) % vs 60.0 (42.0, 65.0) %], all P<0.001; PH-LHD group presented elevated blood levels of BNP, bilirubin, red cell distribution width (RDW), uric acid and cystatin C, while reduced lipoprotein (HDL), allP<0.001. PASP was positively related to biomarkers as BNP, bilirubin, RDW, uric acid and cystatin C, while negatively related to HDL. With the combination of BNP, direct bilirubin and RDW, the predictive value for PH-LHD under ROC curve was 0.828 with the sensitivity at 0.813, speciifcity at 0.708. Conclusion: Blood levels of biochemical markers were statistically different between the patients of PH-LHD and LHD; the combination of BNP, direct bilirubin and RDW showed the higher accuracy for predicting PH occurrence in LHD patients.

Objective To explore a better medication by analyzing retrospectively 179 cases with confirmed auricle pseudocyst.Methods A comparative study was carried out for the clinical effects of injecting triamcinolone acetonide in cavity with that of washing the cyst using dexamethasone and fixing it with gypsum.Results There was significant difference between the two groups(P

Objective To explore the relationship between activation-induced cytidine deaminase (AID) expression and melanoma invasion, metastasis and prognosis, and to evaluate the clinical significance of AID. Methods An immunohistochemical study was conducted to detect the expression of AID in paraffin-embedded tissue sections from 80 cases of melanoma and 23 cases of pigmented nevus. The relationship between the expression of AID and clinicopathological and biological features of melanoma was analyzed. Results The expression rate of AID was significantly higher in melanoma than in pigmented nevus tissue specimens(53.75%(43/80)vs. 13.04%(3/23), P<0.05). AID expression was closely correlated with lymphatic metastasis, Clark grade, depth of invasion and prognosis of melanoma (all P<0.05), but was of no significant difference among patients of different age, gender or nationalities(all P > 0.05). Of 19 melanoma specimens with BRAF mutations, 17 expressed AID, including all the 15 melanoma specimens with the BRAFV600E mutation. Conclusions AID may induce BRAF mutations in melanoma, participate in melanoma invasion and metastasis, and be correlated with melanoma prognosis.

Objective:To analyze one case of diabetes allergic to insulin preparations and investigate the role of clinical pharmacist in the treatment. Methods:Different insulin preparations were tried out after the patient was allergic to one kind of insulin preparation. However, the allergic symptoms were not improved significantly. Clinical pharmacist recommended to use glargine combined with oral hypoglycemic drugs instead of insulin containing protamine for the patient. Results:The allergic symptoms of the patient were improved significantly after the drug adjustment in the hypoglycemic program by clinical pharmacist. The blood glucose was controlled and aller-gic symptoms didn't show again during the hospitalization. Conclusion:Clinical pharmacist can participate in the treatment of diabetes allergic to insulin preparations through identifying allergens accurately and improving individual hypoglycemic program using pharmaco-logical knowledge. It is important to improve the clinical diagnosis and treatment, and ensure and promote the safety of medical treat-ment and drug use.

Objective To compare the diagnostic performances of strain elastography (SE) and shear-wave elastography (SWE) in differentiating benign and malignant solid breast lesions. Methods From January 2015 to December 2015, 150 patients with 155 lesions were examined with SE and SWE respectively in the First Affiliated Hospital with Nanjing Medical University. Elasticity scores on a improved 5-point scale,strain ratio (SR), maximum elasticity (Emax), mean elasticity (Emean), standard deviation of the elasticity (Esd) and the lesion-to-fat elasticity ratio (Eratio) were assessed. The receiver operating characteristic (ROC) curve of SE and SWE parameters were plotted to assess the value in distinguishing benign and malignant breast lesions. The results were compared using the area under the ROC curve (AUC). The accuracy of the parameters with the largest AUC were compared between SE and SWE by McNemar test in different breast imaging reporting and data system (BI-RADS) categories. Results The AUC of elasticity scores, SR, Emax,Emean, Esd and Eratio were 0.823, 0.810, 0.877, 0.835, 0.881 and 0.853, respectively. The SE and SWE parameter with the largest AUC were elasticity scores and Esd respectively. The accuracy of Esd was higher than that of elasticity scores(86.3% vs 64.7%)in 4A lesions (2=4.639, P < 0.05). There were no significant differences in accuracy in other BI-RADS categories. Conclusions Both SE and SWE were helpful for the differentiation of benign and malignant solid breast lesions, and the diagnostic performance of SE and SWE was similar. The optimization of elastography can be achieved by combination with BI-RADS.

Objective: To investigate the multi-imaging diagnostic values, especially MSCT technology in patients with congenital aortic diverticulum with its clinical application. Methods: The MSCT ifndings in 12 patients with congenital aortic diverticulum were retrospectively analyzed. Results: There were 9 patients with right aortic arch and 1 with left aortic arch, all of them having coexisted aberrant subclavian artery which initially dilated like aneurysm by diverticulum changing (Kommerell diverticulum), and there was 1 patient with incomplete double aortic arch with atresia of left arch combining retro-esophageal aortic diverticulum (RAD) and 1 patient with ducts diverticulum. Echocardiogram only made the suggestive diagnosis of speeding up blood lfow or right aortic arch in 4 patients. While MSCT accurately displayed the diverticulum for the location, morphology and with or without other complications. The post-eroanterior chest radiograph indicated “double aortic node” as the special sign in 8 patients. The echocardiogram, X-ray and MSCT for correctly diagnosing the aortic diverticulum were as 0, 72.7% and 100% respectively. Conclusion: MSCT is a rather ideal non-invasive diagnosing method for aortic diverticulum, meanwhile X-ray could also make suggestive diagnosis; if MSCT and X-ray joint with echocardiogram examination may provide the effective supplement for valve structure and hemodynamics condition in relevant patients.

Objective To evaluate the correlations between the cerebral hemodynamic changes of severe acute encephalopathy with the clinical features from emergency periods to stable periods and the value of transcranial Doppler ultrasonography( TCD)in cerebral function assess. Methods Thirty patients with acute brain diseases by assisted mechanical ventilator from Jun 2014 to May 2015 in PICU were included and followed up to Nov 2015,then grouped by Glasgow Coma Scale( GCS),MRI,prognosis( mental sequelae after half a year). Each subject was examined through the temporal bone window by TCD at emergency peri-ods and stable periods. The systolic cerebral blood flow velocity( sCBFV),and pulsatility index( PI)of bilat-eral middle cerebral artery( MCA),anterior cerebral artery,posterior cerebral artery were analyzed. Multivari-ant analysis of variance,repeated measures analysis of variance was conducted to compare sCBFV and PI of MCA among groups in different clinical periods. The variants included sex,disease diagnosis,prognosis, MRI,GCS,and the first abnormal TCD. The variation within groups was tested via a Hotelling T2 test. All sCBFV and PI of each artery and the D-value of sCBFV between the different periods were compared accord-ing to the prognosis groups. Results (1)Five patients could be lateralized,and their lateralization of MRI focus was consistent with the abnormal sides of sCBFV in the stable periods.(2)The D-value of sCBFV in left MCA between the different periods in the poor prognosis group was significantly higher than that in the good prognosis group[(71. 93 ± 58. 21)cm/s vs.(33. 20 ± 30. 23)cm/s,t = -2. 287,P =0. 033].(3) Multivariant analysis of variance showed that GCS classification and disease diagnosis were significantly cor-related with the cerebral hemodynamic changes respectively(P =0. 042,0. 005,respectively).(4)sCBFV and PI of left MCA reduced significantly in the stable periods than those in the emergency periods( P =0. 002,0. 003,respectivly). Conclusion The cerebral hemodynamic changes by TCD from emergency peri-ods to stable periods are consistent with the clinical status,dynamic evaluation by TCD may facilitate the evaluation of brain dysfunction in the severe acute encephalopathy.

Objective: To explore the necessity of multi-slice CT (MSCT) and echocardiogram in diagnosing multiple cardiac myxoma or myxoma originated from special site of heart via analyzing medical imaging features. Methods: A total of 14 patients with multiple cardiac myxoma or myxoma not originated from left atrium fossa ovale were studied; the patients had operation conifrmed diagnosis in our hospital from 2003-02 to 2015-12, the imaging features of MSCT and echocardiography were analyzed and compared. Results: There were 12/14 patients diagnose by echocardiography with the accuracy of 85.7% and 11 patients diagnosed by MSCT with the accuracy of 84.6%. MSCT and echocardiography had similar pre-operative accuracy and complimentary advantages for diagnosing multiple cardiac myxoma or myxoma not originated from regular site of heart. Echocardiography was superior for examining the motion, pedicle position, shape and attachment point of cardiac myxoma; MSCT may exclude pulmonary embolism and coronary artery disease at meanwhile. Conclusion: Unconventional cardiac myxoma not only has similar image signs to typical single myxoma from left atrium, but also has the speciifc features; MSCT combining echocardiogram examinations could make more accurate diagnosis and provide a better condition for surgical treatment.
