Objective To explore the characteristics of chest multi-slice spiral CT and dynamic changes in adult patients with se-vere adenovirus pneumonia.Methods Clinical and CT data of 6 patients with severe pneumonia in an epidemic of the respiratory ade-novirus infection were retrospectively analyzed.The impact of hormone therapy was also studied.Results The first chest CT exami-nations in 6 patients were performed 2.22 ± 0.75 days after fever.CT showed segmental consolidation with ground-glass opacity (GGO)in one case,patchy consolidation with GGO in 3 cases,patchy interstitial changes in one case and small nodules in one case. The duration reaching the standards of severe pneumonia was 6.1 7 ± 0.37 days from the onset.During severe phase chest CT showed a range of lobar consolidation in one case,lobar in 2 cases,segmental in 2 cases or patchy in one case,consolidation with GGO in 5 cases.In all cases the lesions were commonly seen in the lower lobes of bilateral lungs.Multiple lobes were involved in 2 cases.After methylprednisolone treatment,no new lesion was showed but the early lesion was enlarged.During the first 2 to 4 days GGO absorbed completely in 6 cases,consolidation absorbed completely in one case and mostly in 5 cases.Conclusion Chest CT findings of severe adenovirus pneumonia in adult are single or multiple lobar or segmental consolidations with or without GGO which distribute mainly at lower lobes.

Objective To evaluate the value of three-dimensional power Doppler imaging(3D-PDI) in the discrimination between benign and malignant endometrium in women with postmenopausal bleeding. Methods Eighty-four women with post menopausal bleeding who examined by 3D-PDI were enrolled. All patients scheduled for pathological examination were divided into benign group (30 cases with endometrial polyps and 34 cases with hyperplasia) and malignant group (20 cases with endometrial carcinoma). Endometrial volume, vascularity index ( VI) , flow index ( FI) and vascularity flow index ( VFI) were measured. The diagnostic value of parameters derived from 3D-PDI was evaluated by using the receiver operating characteristic ( ROC) curve. Results Differences of these parameters (VI, FI and VFI) were considered statistically significant between two groups, the parameters of endometrial volume had no significant differences between two groups; the area under ROC curve(AUC) of the meaningful data were 0.976,0.888 and 0.894 respectively. Among these parameters, VI had the highest diagnostic value for discriminating between benign and malignant endometrium, the cut-off value of which was 2. 97 with a sensitivity of 95% and a specificity of 86%. Conclusions 3D-PDI is a good diagnostic tools in the discriminations between benign and malignant endometrium in women with postmenopausal bleeding.

To evaluate the application of intracavitary three-dimensional ultrasonography in the diagnosis of polycystic ovary syndrome ( PCOS). The three-dimensional volumes of ovary were measured by intracavitary ultrasonography in 40 PCOS patients and 40 normal controls. The diagnostic value of parameters derived from three-dimensional ultrasonography was evaluated by using the receiver operating characteristic (ROC) curve. The ovarian volume, stromal volume, and the stromal/total volume ratio in PCOS group were significantly higher than those in control group (both P ＜ 0. 05 ) ; the area under ROC curve ( AUC ) of them were 0. 876, 0. 926, 0. 886 respectively. Among these parameters, stromal volume had the highest diagnostic value for PCOS, the cut-off value of which was 7.52 cm3 with a sensitivity of 88% and a specificity of 90%. Volume parameters of ovary measured by intracavitary three-dimensional ultrasonography can offer quantitative information for the diagnosis of PCOS.

ObjectiveTo present 4 cases of primary c ar cinoid tumor of urinary bladder and to discuss the characteristics,diagnosis,tre atment and prognosis.MethodsA retrospective study of p athological and clinical data of 4 cases of primary bladder carcinoid tumor was made.Three were male patients and 1 female with an average age of 58.Two cases w ere considered as benign carcinoid tumor whereas the other 2 carcinoid of high malignancy.All of them presented macroscopic or microscopic hematuria but with no carcinoid syndrome noted.ResultsOne case of maligna nt carcinoid tumor with deep muscle invasion underwent radical cystoprostatectom y and adjurvent chemotherapy,but the prognosis was poor (died 5 months after the operation).Transurethral resection were performed for 2 cases of benign carcino id tumor and 1 case of focal malignant carcinoid with good prognosis.ConclusionsThe primary carcinoid tumor of urinary bladder has no specific symptoms,and should be diagnosised on histopathologic studies.Surgical intervention is the mainstay to treat the disease but the prognosis is hard to b e predicted.

To explore the diagnostic values of real-time elastosonography quantitative parameters in uterine fibroids and adenomyoma.The clinical data of 175 cases were analyzed retrospectively.Strain ratios (B/A) of lesion and normal adjacent myometrium were measured and mean B/A was calculated.The average B/A of uterine fibroids and adenomyoma was 3.81 ±0.52 and 1.39 ±0.46 respectively.And there was significant statistic difference (t =2.563,P ＜ 0.05).the accuracy rates of real-time elastosonography in the diagnosis of uterine fibroids and adenomyoma were high at 97.4％ (148/152) and 95.3％ (122/128) respectively.Real-time elastosonography has high diagnostic values for uterine fibroids and adenomyoma.

Objective To analyze gene expression profiles of biopsy specimens from breast cancer patients who were treated with neoadjuvant chemotherapy(NAC) after biopsies, and to identify the genes which are closely associated with the efficacy of neoadjuvant chemotherapy with T/FAC [docetaxel(Taxotere), 5-fluorouracil, doxorubicin and cyclophosphamide] or T/FEC (Taxotere, 5-fluorouracil, epirubicin and cyclophosphamide) regimen.Methods We retrieved and collected gene expression profiles from publicly available databases.Four datasets, a total of 844 samples, were finally retained because all the patients had received a uniform neoadjuvant chemotherapy regimen.Response to neoadjuvant chemotherapy was categorized as a pathological complete response (pCR) or residual invasive cancer (RD).The differentially expressed genes (adjusted P-value<0.05) and therapeutic efficacy were analyzed and explored.Results After differential analysis, genes whose expressions were higher or lower in pCR group than in RD group were identified in each of the four datasets, respectively.There were 34 and 42 genes which were simultaneously more highly expressed or more lowly expressed in pCR group than in RD group in the four datasets.The unsupervised clustering, based on the 76 intersection genes, showed that the pCR specimens tended to form one cluster and the RD tended to form the other.Conclusion The seventy-six differentially expressed genes are associated with the efficacy of neoadjuvant chemotherapy and are likely to be novel predictive biomarkers for the efficacy of neoadjuvant chemotherapy.

Objective To elucidate the prevalence and risk factors of cardiovascular disease (CVD) in end-stage renal disease (ESRD) patients on peritoneal dialysis (PD), and to investigate the associated problems in treatment. Methods A total of 254 PD patients in our division were enrolled in this study. CVD history, laboratory measurements, examinations of carotid atherosclerosis and left ventricular hypertrophy by ultrasonography were collected and associated factors were analyzed. The median follow-up time was 49 months. Results The overall prevalence of CVD was 37% (93/254). Diabetes, longer dialysis duration, hypertfiglyceridemia, hypoalbuminemia, hypoprealbuminemia were commonly found in the patients with new CVD event. The patients without pre-existing CVD had the higher Ccr, Kt/V, D/Pr, nPCR, serum albumin level. In those with pre-existing CVD, the hypertriglyceridemia and the duration of dialysis were independent predictors of progression of CVD. Differences of LAD, LVST, LVMI and IMT were significant between with and without pre-existing CVD groups. Kaplan-Meier curves showed that the presence of CVD was the independent risk factor of survival. Alb<330 g/L, LAD>39.6 mm and peritonitis were risk factors of CVD. Conclusion The prevalence of CVD in PD patients is quite high. CVD history should be realized, dialysis adequacy should be maintained, and peritonitis should be prevented.
