Objective To investigate the levels of pro-inflammatory cytokine interferon (IFN)-γand anti-inflammatory cytokine interlenkin (IL)-10 in expressed prostatic secretions (EPS) of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and their clinical significance. Methods The levels of IFN-γ and IL-10 in EPS of 20 patients with CP (type Ⅲ A, group A ), 20 patients with CPPS (type Ⅲ B,group B) and 10 healthy men (control group) were measured using enzyme-linked immunosorbent assay (ELISA). The results were analyzed comparatively with NIH-chronic prostatitis symptom index (NIH-CPSI).Results The levels of IFN-γ in EPS of group A and group B were ( 14.92 ± 7.85 ), ( 13.74 ± 5.96) ng/L respectively, which were higher than that in control group [(7.47 ± 1.40) ng/L] (P < 0.05 ). And the levels of IL-10 in EPS of group A and group B were (216.40 ± 33.65 ), (223.70 ± 45.21 ) ng/L respectively, which were higher than that in control group [( 162.10 ± 43.81 ) ng/L] ( P < 0.05 ). There was no statistically significant difference between group A and group B. No correlation between NIH-CPSI and IFN- γ,IL-10 levels in EPS(P > 0.05 ). Conclusion IFN-γ and IL-10 have a very important role in etiology of CP/CPPS and they can be the objective parameters in the diagnosis of CP/CPPS.

Objective To study the prevalence, clinical characteristics and risk factors of HIV-related lipodystrophy syndrome (HIV-LD) in our cohort of HIV-1 infected Chinese adults. Methods In a cross-sectional study, 55 HIV-infected patients were recruited from the HIV clinic of Peking Union Medical College Hospital; most of them were undergoing the first-class highly active antiretroviral therapy (HAART) of today in China. Lipoatrophy or lipohypertrophy was defined if there was concordance between the report of fat change and clinical examination of the participants. Whole body dual-energy X-ray absorptiometry (DEXA) scanning was performed. Results Prevalence of clinical body fat redistribution in the present study was 47.3%. Comparing with non-LD patients, HIV-LD patients had elder age and longer exposure to HAART(P<0.05). HAART exposure and stavudine(d4T) usage were two independent risk factors for HIV-LD. Conclusions HIV-related fat redistribution does exist in Chinese HIV population. Peripheral lipoatrophy occurs commonly in HIV-infected adults but is not associated with increased trunk fat. HAART exposure and especially d4T usage are independent risk factors for HIV-LD.

Background and purpose: The literature on dose-volume parameters and pneumonitis is extensive. The results are inconsistent, both for the best predictive metrics and significant comorbid factors. This study aimed to investigate a prospective functional equivalent uniform dose (fEUD) with perfusion single photon emission computed tomography (SPECT) images as predictors of radiation pneumonitis (RP) in patients undergoing curative radiotherapy (RT). Methods: Functional lung imaging was performed using SPECT for perfusion imaging. Perfusion factors were defined as the mean percentile perfusion levels of the 4 areas, top to 75%, 75% to 50%, 50% to 25%, 25% to 0%, re-spectively. fEUD was calculated from perfusion factors and standard dose-volume parameters extracted from treatment planning computed tomography (CT) scans. Total lung (TL), ipsilateral (IL) and contralateral lung (CL) volumes minus gross tumor volume (GTV), whole-lung V5, V20, whole lung fEUD, IL and CL fEUD, and general equivalent uniform dose (gEUD) were analyzed to evaluate correlations between RP using Common Terminology Criteria for Adverse Events (CTCAE) version 4.03. Statistical significance was defined as P<0.05. Results: A total of 15 patients treated with intensity modulated RT or 3D conformal RT were analyzed, grades≥3 RP were observed in 6 patients. There was only a trend toward significance for unilateral (UL) fEUD of higher dose side (P=0.007). Whole-lung V5, V20 were almost identical between patients who developed pneumonitis and patients who did not, as the values were below the recommended thresholds from published papers. Unilateral fEUDs were linear with unilateral gEUDs (t=0.815, P=0.000). Conclusion: SPECT-based equivalent uniform dose appears to be a better predictor of RP compared to stan-dard dose-volume parameters. Planning constraints should aim to keep unilateral fEUD below 21 Gy.

Objective To describe a new kind of Y-shaped metallic stent delivery system and evaluate its feasibility and preliminary effect for managing multiple airway stenoses involving the lower trachea and the tracheal carina.Methods The Y-shaped metallic stent delivery system consisted of three- tier structure.The inner-tier was composed of four parallel guiding tubes,which was used for two guidewires and two threads passing through,the middle-tier was delivery catheter,which contained the four guiding tubes,and the outer-tier was introducer sheath.Under the fluoroscopic guidance,15 patients with multiple stenoses involving the lower trachea and the tracheal carina were treated with the new covered self-expandable Y-shaped metallic stents.Results Stent placement in the tracheo-bronchial tree was technically successful in all patients with obliteration of the dyspnea immediately after stent placement,and SaO_2 was increased form preoperative 75%—89% to postoperative 96%—99%.During follow-up a period of 3—58 weeks (M 22 weeks),all stenosis were resolved without stent-related complications,and the general physical of all 15 patents was improved with no occurrence of obviously dyspnea and bleeding.Karnofsky performance status(KPS)was improved from preoperative 26%—45% to postoperative 72%—95%.Five patients died of the following causes unrelated to stent insertion:multiple organ failure(n=3),cachexia(n=1)and pulmonary infection caused by gastrobronchial fistula(n=1),and the remaining 10 patients were alive with no evidence.of dyspnea at the time of this report.Conclusion Deployment of the covered Y-shaped metallic stent with the use of Y metallic stent delivery system in the management of airway stenoses involving the lower trachea and the tracheal earina was a simple and safe procedure and with a good short-term clinical efficacy.

This study is to investigate the effect of osthol on osteoclasts' activity, bone resorption as well as apoptosis in vitro, and explore the mechanism of osthol in preventing osteoporosis. Osteoclasts were separated from long-limb bones of new born rabbits, cultured in 24-well plate with glass slices and bone slices, and treated by 1 x 10(-5) mol x L(-1) osthol. Osteoclasts were identified by observing live cells with phase contrast microscope, HE staining, TRAP staining and toluidine blue staining of bone resorption pits. The numbers of bone resorption pits were counted as well as the surface area of bone resorption on bone slice. Osteoclasts were stained with acridine orange to detect the cell apoptosis. The ratio of apoptotic osteoclasts was observed under fluorescence microscope. The gene expression of RANKL, OPG, TRAP and p-JNK1/2 protein expression were examined using real time PCR and Western blotting, respectively. Comparing with the control group without osthol, the rates of apoptotic osteoclasts increased obviously and the number and area of bone resorption pits decreased evidently with 1 x 10(-5) mol x L(-1) osthol. There is significant difference between control group and experiment group treated by 1 x 10(-5) mol x L(-1) osthol. Therefore, the osthol through RANK+RANKL/TRAF6/Mkk/JNK signal pathway inhibits the osteoclasts activity, enhances osteoclasts apoptotic and inhibits the bone resorption.

OBJECTIVETo study the accuracy of the application of the intrapartum fetal oxygen saturation (FSO2) monitoring in predicting fetal acidosis and diagnosing intrauterine fetal distress.
METHODSContinuous FSO2 monitoring as well as internal and external fetal heart rate monitoring were applied respectively in 60 women in labor during active phase of the first stage and the second stage. All the monitoring methods were validated with standard sensitivity, specificity, positive predictive value, negative predictive value, and accuracy on the bases of Apgar score and cord artery blood analysis.
RESULTSThe mean FSO2 in the active phase of the first stage were significantly higher than in the second stage of labor. FSO2 correlated with pH, PO2, PCO2, and base excess (BE) of cord blood to a significant degree. There was linear correlation between FSO2 and cord artery blood pH. Using 30% cutoff diagnosing intrauterine fetal distress, the sensitivity, specificity, and accuracy were 80%, 100% and 98.3%, respectively.
CONCLUSIONFSO2 monitoring is an effective method diagnosing intrauterine fetal distress.
