Objective To discuss manifestations of neurogenic tumors on chest wall on CT imaging and pathology.Methods 7 patients with neurogenic tumors on chest wall confirmed surgically and pathologically were reviewed.To facilitate differential diagnosis,3 cases of malignant sarcoma were reviewed for their features on CT.Results 4 out of 5 cases of neurinoma were benign,with one case showing even density on plain CT scan,3 were poorly even,one case showed obvious evenness after enhancement,and 1 case was poorly evenly enhanced,2 benign cases had compression absorption of surrounding bone of scapula or ribs.One case of moderate malignancy was uneven in plain scan and slightly enhanced after enhancement procedure,and neighboring bone of scapula and rib were compressed and destroyed and absorbed,and neighboring muscular interspace and upper mediastinum were involved.One case showed single lesion of neurofibroma,displaying relatively even density on plain scan and moderate unevenness after enhancement procedure,as well as compression and absorption of neighboring ribs.One case of neurofibroma had multiple lesions,showing uneven density on plain scan.This case did not undergo enhanced scan.The remaining 3 cases were all sarcoma including 2 cases of fibrosarcoma and one case of synovial sarcoma.Conclusion Mass of soft tissues that are situated on chest wall or paravertebral area and with smooth edge are suggestive for benign neurogenic tumor.On the contrary,rough edge and coarse shape and infiltration into neighboring tissues are characteristic for malignant ones.

OBJECTIVE To investigate the characteristics and risk factors of nosocomial infection(NI) in patients with hematological malignancies(HM),and provide the bases for making the controlling measures of NI.METHODS Using the targeted monitoring to study NI in patients with HM,and recording 14 factors such as the time of hospitalization,chemotherapy,count of leukocyte and absolute neutrophil count(ANC) and so on.The data were analyzed with unifactorial ?2 test and multifactorial Logistic-regression analysis.RESULTS Among 242 patients with HM the prevalence of NI was 35.5%(86/242) and the prevalence of NI time-cases was 52.9%(128/242).Among 86 patients of NI there were 27 patients occurred multiple sites NI(31.4%).The main infection sites were upper respiratory tract,gastrointestinal tract,lower respiratory tract,oral cavity and blood.66.7% Of NI happened in the period of chemotherapy and 7 days after chemotherapy.The time of hospitalization and ANC were independent risk factors of NI in patients with HM.CONCLUSIONS The patients with HM are susceptible population of NI,and NI often occurs in the period of chemotherapy and 7 days after chemotherapy.So medical staff should strengthen monitoring,and shorten the time of patient hospitalization and of recovery of ANC to reduce the prevalence of NI efficiently.

OBJECTIVE By investigating the incidence of nosocomial infection with objective monitoring method and prospective overall monitoring method, to analyze the advantage and significance between two methods. METHODS Using the objective monitoring method to study the incidence of nosocomial infection of patients after neurosurgical operation from May to December in 2003 and using the prospective overall monitoring method to study the incidence of nosocomial infection of patients after neurosurgical operation from May to December in 2002. All data were analyzed with Stata 7.0 soft. RESULTS There were 100 cases occurring nosocomial infection in 267 neurosurgical operation patients. The patient incidence of nosocomial infection was 37.5% and the rate of nosocomial infection cases was 50.9% with objective monitoring method, that was significant higher than those data coming from May to December in 2002 with 248 cases under prospective overall monitoring method, with which the patient incidence of nosocomial infection and the rate of nosocomial infection cases were 20.2%(50 cases ) and 21.4%(53 cases), respectively . Statistically significant difference was found (P

0.05).The average rate of three times NI prevalence surveys was 5.23% and that of NI prospective overall(monitoring) method in the same months was 6.60%,the statistical difference between them was found(P

OBJECTIVETo study the predicting effect of proly 4-hydroxylase beta polypeptide (P4HB) in treating non-small cell lung cancer (NSCLC) patients by Yiqi Chutan Recipe (YCR).

METHODSTotally 46 stage III and IV NSCLC patients were treated by YCR for 4 therapeutic courses. Effect was assessed by RECIST of solid tumor. P4HB expression was detected in the lung cancer tissue by immunohistochemical assay. Factors affecting disease control rates (DCR) of YCR were analyzed by Logistic regression analysis. The correlation between P4HB expression and the effect of YCR was analyzed.

RESULTSThe DCR of advanced NSCLC treated by YCR was 36.96% (17/46 cases). P4HB was high expressed in advanced lung cancer tissue (6/15 cases). Gender, initial treatment, and retreatment are independent factors for affecting DCR of treating lung cancer by YCR.

CONCLUSIONP4HB might be taken as a factor for predicting the effect of YCR in treating NSCLC.

This study was purposed to confirm the practical efficacy of reducing indicating germs suspended in plasma by riboflavin and photosensitized inactivation and to evaluate its influence on activation of apheresis platelet concentrates. The synergistic effects of riboflavin combined with ultraviolet irradiation on inactivation of germs were investigated by using Escherichia Coli (E. coli) and Staphylococcus Aureus (S. aureus) as Gram⁻ and Gram(+) indicating germs, respectively. The activation status of apheresis-platelet concentrates treated with riboflavin combined with ultraviolet irradiation was detected by flow cytometry. The results showed that when 50 μmol/L of riboflavin was combined with 6.2 J/ml of ultraviolet irradiation, the T/E ratios reached 1.42 for E. coli and 1.68 for S. Aureus, and reduction of E. Coli and S. Aureus were 3.87 Logs and 3.82 Logs respectively; the CD62p expression level on germ-inactivated platelets stored at 22 degrees C for 0 and 5 days were 4.92% and 36.18% respectively, which slightly increased as compared with controls (3.94% and 32.03)% (p < 0.05). It is concluded that combination of riboflavin with ultraviolet irradiation displays well synergistic effects which can reduce E. Coli and S. Aureus counts, but no significantly influence on platelets. The partial activation of liquid platelets mainly presents metabolism damage during storage, which is found at an acceptable level.

Objective To investigate the enlarged perivascular space (EPVS) and its clinical significance in patients with cerebral small vessel disease (CSVD).Methods One hundred seventy-four patients with CSVD and 86 patients without CSVD admitted to Jinling Hospital,Clinical School of Nanjing University School of Medicine from October 2011 to February 2012 were recruited.All patients underwent cranial MRI examination (including diffusion-weighted imaging and fluid attenuated inversion recovery sequences).The numbers of EPVS and anatomic distribution in all the subjects of both groups were analyzed.The receiver operator characteristic (ROC) curve was used to investigate its diagnostic critical value of anatomic distribution.Results Multivariate logistic regression analysis showed that EPVS in basal ganglia region (odds ratio [OR] 1.491,95％ confidence interval [CI] 1.165-1.909; P =0.002) and EPVS in centrum semiovale (OR 1.279,95％ CI 1.022-1.601;P=0.032) were independently associated with CSVD.EPVS in the basal ganglia region and the centrum semiovale in patients with CSVD was significantly more than that in patients with non-CSVD (all P ＜0.001).Its corresponding diagnosis cut-off points of CSVD were 4 and 6 respectively.The area under the ROC curve and the diagnostic sensitivity and specificity were 0.859,72.4％,93.0％ and 0.808,65.5％,95.3％,respectively.Conclusions EPVS contributes to the diagnosis of CSVD.When using EPVS to diagnose CSVD,the anatomical sites need to be distinguished and establish appropriate diagnostic critical value.
