Objectives To investigate the eosinophil in t he lung of patients died of asthmatic attack.Methods All samples were divided into three groups.G roup A died of asthmatic attack,Group B once had asthmatic history,died of non-asthmatic attack,Group C had no asthmatic history.Immunohistochemistry me thod was used to st udy the positive cells of EG 1 and EG 2 in lungs. Results The number of positive cells of EG 1 and EG 2 in the l ung died o f asthmatic attack was significantly higher than the other two groups.T here was no difference between Group B and Group C.There was no difference be tw een the larger bronchial and smaller bronchial and lung parenchyma.However,th e number of positive cells of EG 2 in the smaller bronchial and lung parenchyma was higher than that in the larger bronchi.Conclusion A large amount of eosinophiles infiltrate into the lung and airway of cases died of asthmatic attack,and mainly in the small er bronchi and lung parenchyma.

Objective To observe the curative effect of cervical traction combined with low-cycle or intermediate frequency electrical current in cervical vertebrae.Methods 171 patients with cervical vertebrae were randomly divided into the therapy group and control group,86 cases in therapy group were performed the curative measure of cervical traction and low-cycle,85 cases in control group underwent the curative measure of cervical traction and intermediate frequency electrical current.Both of the two groups carried out continuous therapy for 10 days.Results There was significant difference before and after treatment within each group in CASCS score(P ＜ 0.01)and there was also significant difference after treatment between the two groups(P ＜ 0.05),the effective rate of therapy groupwas significant higher than that of control group(P ＜ 0.05).Conclusion The methods of cervical traction and low cycle or intermediate frequency electrical current has better curative effect in cervical vertebrae and cervical traction and low-cycle do much benefit in cervical vertebrae treatment.

Objective To observe and analyse the efficacy of retrograde gonarthritis with interference current and drug-iontophoresis direct current. Methods 185 patients with retrograde gonarthritis were randomly divided into treatment group 92 cases and control group 93 cases. The patients in treatment group underwent interference current and drug-iontophoresis direct current and patients in control group performed modulated medium frequency drug-ionto-phoresis direct current for two treatment courses. Results The comprehensive score of various kind of symptom such as pain、swelling、flexion、walking ability, up-down stair ability in treatment group significantly improved than that of control group (P < 0.01). Conclusion The interference current and drug-iontophoresis direct current is one of effec-tive and safe measurement in treating arthritis with main manifestation of pain and soft tissue disease.

BACKGROUNDTo detect quantitatively HCMV DNA in peripheral blood leukocytes to monitor the status of HCMV infection, evaluate the effectiveness of antiviral treatment with ganciclovir (GCV) combined with intravenous immunoglobulin (IVIG) and find out the relationship among the HCMV DNA levels, the state of infection and the clinical outcome.The long-term goal of the study was to establish a molecular diagnostic standard for HCMV infection in children.

METHODS45 cases of suspected HCMV-infected children were examined by PCR, ELISA and fluorescent quantitative (FQ)-PCR, respectively. Twenty five HCMV hepatitis cases of the 45 were randomly assigned to a treated group or a control group. Both groups were treated with prednisone, glucurone, Luminal and Xiaoyanlidanpian. But the treated group was given with GCV+IVIG in addition. Each infant of the two groups was checked with FQ-PCR at the five time points.

RESULTSThe positive rates of PCR, ELISA and FQ-PCR were 60.00%, 33.33% and 66.67%,their sensitivities were 84.38%, 46.88% and 93.75%, respectively. There was no significant difference in viral DNA copy numbers between the two groups before being treated (P>0.05), but there was significant difference between HCMV hepatitis and normal infants (P<0.001). Although viral load of both groups decreased in both groups, the viral load of the treated group decreased more significantly. The level of HCMV DNA fell to 103 copies/ml at second time point while that of the control group fell to the same level after third time point. The differences between the two groups at each time point were statistically significant (P<0.001). The results of 135 person times testing indicated that 103 copies/ml of FQ-PCR can be taken as a critical value for prediction of active HCMV infection.

CONCLUSIONSFQ-PCR may be one of the effective methods for diagnosis of HCMV disease; it can offer a key index in the diagnosis of HCMV active infection; dynamic detection of HCMV viral load can play a role not only in monitoring antiviral therapy, but also in evaluating the development and prognosis of HCMV disease.

Objective To provide objective parameters for differentiating pancreatic cystic tumors via using computed tomography texture analysis (CTTA) to quantify the special imaging features of pancreatic cystadenomas.Methods Enhanced CT images of pancreas from patients who were admitted in Department of Radiology in First Hospital affiliated with Zhejiang University and First People's Hospital of Hangzhou City and pathologically diagnosed as pancreatic serous cystadenomas (n =48) and mucinous cystadenomas (n =34) from January 2009 to December 2016 were retrospectively analyzed.Regions of interest were drawn on the parenchymal phase CT images in 5 slices according to the border of the tumors.Mean grey level intensity (M),variance (V),entropy (E),skewness (Ske) and kurtosis (Kur) were obtained from fine texture (σ =1.0) to coarse texture (σ =2.5).Receiver operating characteristic (ROC) curve for texture parameters with statistically difference was drawn,and the area under curve (AUC),diagnostic sensitivity and specificity were calculated.The diagnostic accuracy of senior and junior doctors was compared with the traditional CT analysis method.Results Reliability coefficient of the two radiologists was 0.809 ～ 0.997 with high consistency.Compared with mucinous cystic tumors,serous cystadenomas had a significantly different V (5.93 ± 9.02 vs 1.29±0.62),E (2.39±0.61 vs2.02±0.39) and Kur(30.18 ±42.55 vs 8.80-±4.34) in Ske0 of 2.5 (P ＜0.05),and there were no statistically significant differences on other parameters.The AUC of differential parameters for diagnosing two kinds of cystic tumors ranged from 0.56 to 0.84.The diagnostic accuracy of the traditional CT analysis method by junior doctor and senior radiologist was 60％ and 71％,respectively.Conclusions CTTA can not only effectively quantify the heterogeneity of pancreatic cystadenomas,but also is effective in the differentiation.
