As one of the most serious types of psoriasis, pathogenesis of erythrodermic psoriasis (EP) is unclear so far. In this study, we aimed to detect the levels of Th1/Th2 cytokine-associated transcription factors and T-lymphocyte clone in peripheral blood mononuclear cells (PBMCs) derived from EP patients, and gene expression level of T-bet/GATA-3 in skin lesion. The potential role of Th1/Th2 reaction pattern played in the pathogenesis of EP was also discussed. Serum levels of IFN-γ, IL-2, IL-4 and IL-10 were quantified by ELISA among 16 EP patients, 20 psoriasis vulgaris (PV) patients and 15 healthy controls. The expression levels of T-bet/GATA-3 in the skin lesion and PBMCs were examined by real-time qPCR. The ratio of Th1/Th2 was measured by flow cytometry. The levels of IFN-γ, IL-2, IL-4 and IL-10 were higher in EP patients than in the healthy controls. The levels of IL-4 and IL-10 were 69.44±11.45 and 12.62±4.57 pg/mL, respectively, in EP patients, significantly higher than those in PV patients and healthy controls (P<0.05). Flow cytometry revealed the levels of both Th1 and Th2 in PBMCs from EP patients were higher than those in healthy controls, and the Th1/Th2 ratio was dramatically lower than in PV patients (P<0.01). The ratios of IFN-γ/IL-4 and T-bet/GATA-3 in EP patients were both less than 1.0, suggesting a reversal when compared with the other two groups. Our study indicated that the EP patients exerted a Th1/Th2 bidirectional response pattern, and the balance of Th cell subsets inclines to Th2, which might be one of the important mechanisms of EP pathogenesis.

Objective Acute pulmonary thromboembolism(PTE)patients with right ventricular dysfunction(RVD)may benefit from thrombolytic therapy but may end up with worse prognosis.RVD was assessed in prognosis to which a model on it was constructed to decide the indexes correlated to the best prognosis.Methods This prospective study included 520 consecutive acute PTE patients from 41 hospitals in China between June 2002 and February 2005.All the patients were evaluated by transthoracic echocardiography(TTE),CT pulmonary angiography(CTPA),laboratory tests,and blood gas analysis.Physicians were asked to record all the clinical manifestations.Data from Univariate analysis demonstrated the parameters correlated with an 14-day clinically adverse outcomes.Multiple logistic regression analysis was used to decide the independent predictors and to construct a prognostic model.Results Mcan age of the patients was 57.4±14.1 years and 323 of them(62.1%)were male.The 14-day mortality in normotensive patients with RVD was higher(2.0%vs0.4%,P＜0.01)than those without.ROC curve showed the best cut.ofr values of RVED/LVED and SPAP for 14-day prognosis were 0.67 and 60 mm Hg,respectively.SPAP independently predicted 3-month clinicaI outcomes(P＜0.01).Results from Univariate analysis demonstrated tllat 24 parameters were correlated with an adverse 14-day clinical outcomes.which include palpation,syncope,panic,cyanosis,respiratory rate≥30/min,pulse≥110/min,jugular vein,accentuation of P2,murmurs in tricuspid area,time interval from onset,creatine phosphokinase(CPK),lactate dehydrogenase (LDH).alveolar-arterial PO2 difierence(PA-aO2),white blood cell(WBC)＜4.0×109/L or＞10.0×109/L,platelet.thrombus on TTE,RV/LV＞1.1,TRPG＞30 mm Hg,IVCmin＜8 mm,RVD,RVED/LVED＞0.6,SPAP＞60 mm Hg.RVWM.PTE range larger than two lobes or seven segments on CTPA.Furthermore,a multiple logistic regression model implied 8 predictors including RVD,RVED/LVED＞0.6,SPAP＞60 mm Hg,pulse≥110/min,accentuation of P2,Syncope,CPK,WBC＜4.0×109/L or＞10.0×109/L be independent predictors of an 14-day clinically adverse outcome(P＜0.01).This model seemed to fit well (P＜0.001).Wle chose a cut-off value as P≥0.2 and compared the model to the original derivation samples.Data showed that the sensitivity(true positive rate)was 81.82%,specificity was 92.11%.false positive rate was 18.18%.coincidence was 91.14%.and the concordarlCe rate was 80.96%.Conclusion RVD seemed a nice discriminator for poor prognosis in norrnotensive patients.Early detection of RVD(especially RVED/LVED＞0.67 and/or SPAP＞60 mm Hg)was beneficial for identifying patients at high-risk and the multiple logistic regression model(P＜0.001)could be well fitted.

OBJECTIVETo assess the efficacy and safety of Xiaozheng pills in treating mastoplasia.

METHODClinical trials were carried out by five hospitals. In each hospital, patients were divided into two groups with one group 24 patients (trial group) and the other 24 patients (control group). Total 240 patients were included in the study. According to randomized, double-blinded and placebo-controlled clinical study, the trial groups were treated by Xiaozheng pills with Rujiekang mimetic (placebo) and the control groups were treated by Rujiekang with Xiaozheng pills mimetic (placebo). Symptoms, laboratory test results as well as ADR were evaluated after 1 period of treatment.

RESULTThe overall response rates of trial group and control group were 93.8% and 88.6% respectively, no statistic difference between the two groups. No deleterious effect in both groups and the indexes of safety were normal.

CONCLUSIONThese results suggest that Xiaozheng pills are effective and safe in treating mastoplasia caused by qi stagnation, blood stasis or/and stagnation of phlegm.

OBJECTIVETo investigate the expression of androgen receptor (AR) and hepatitis B virus X protein (HBx) in hepatocellular carcinoma (HCC), and analyze the relationship between AR and HBx expressions.

METHODSTumor tissues and peritumoral tissues of 83 HBV-associated HCC cases were investigated in this study. Fourteen cases of HBV-negative HCC and 13 cases of hemangioma peritumoral tissues were considered as control. AR and HBx mRNA levels were determined by quantitative fluorescence real-time RT-PCR and their protein levels were assayed by Western blot. The expression of AR and HBx proteins in tissues were examined with EnVision immunohistochemical staining. The methylation status of AR promoter was determined using methylation-specific PCR (MSP).

RESULTSBoth expression levels of AR mRNA and protein of the peritumoral tissues were significantly higher (0.17) than that of tumor tissues (0.09) in HBV-associated HCC (P < 0.01), but such a difference was not found in HBV-negative HCC (0.06 vs. 0.07, P > 0.05). The level of AR expression in peritumoral tissues was associated with tumor differentiation in HBV-associated HCC. AR mRNA and protein levels of peritumoral tissues in HBV-associated HCC were significantly higher than that in HBV-negative HCC and hemangioma (all P < 0.05). In the tumor tissues, HBV-associated HCC had significantly higher AR expression than HBV-negative HCC at mRNA level (P < 0.05), but not at protein level. Spearman rank correlation analysis showed that the AR mRNA or AR protein levels were positively correlated with HBx in both tumor and peritumoral tissues in HBV-associated HCC, but the expressions of AR and HBx were not associated with AR promoter methylation status. The relative expression levels of AR mRNA and protein in the HBV-associated peritumoral tissues were negatively correlated with tumor differentiation (r = -0.213, P < 0.05; r = -0.313, P < 0.05), the higher the AR expression, the poorer differentiation. But this correlation of AR mRNA and protein was not shown in the hepatocellular carcinoma tissues.

CONCLUSIONSHBx may enhance AR expression in HBV-associated HCC, but AR promoter demethylation maybe not been involved in its main mechanism. An increased AR expression is probably an early event during the development and progression of HBV-associated HCC, and AR expression in the peritumoral tissue is correlated with HBV-associated HCC differentiation. AR may play different roles in HBV-associated HCC and HBV-negative HCC.

OBJECTIVETo discuss the surgical treatment of multilevel lumbar degenerative spondylolisthesis.

METHODSFrom March 2005 to September 2008, 25 cases of multilevel lumbar degenerative spondylolisthesis were treated with total laminectomy, reduction of spondylolisthesis and 360 degrees circumferential fusion through interbody (PLIF), transverse process (PLF) and pedicle screw fixation. All cases were followed up for 0.5 - 4 years. The Lenke grading system was used to assess the spinal fusion and Henderson grading system was used to assess the clinical outcomes.

RESULTSComplete reduction of spondylolisthesis was achieved in all cases. The bone fusion was grade A in 23 cases, grade B in 2 cases. The clinical outcome was excellent in 16 cases, good in 6 cases and poor in 3 cases.

CONCLUSIONSThe pathogenesis of lumbar degenerative multilevel spondylolisthesis is different from that of single-level spondylolisthesis. Complete decompression, reduction of spondylolisthesis sufficient fusion and reliable pedicle screw fixation can provide successful interbody fusion and satisfactory clinical results.It's crucial to reduce multilevel spondylolisthesis by proper techniques based on different types of listhesis.

BACKGROUNDAcute pulmonary thromboembolism (APE) causes right ventricular dysfunction (RVD) and cardiac troponin I (cTnI) elevation. Patients with RVD and cTnI elevation have a worse prognosis. Thus, early detection of RVD and cTnI elevation is beneficial for risk stratification. In this study, we assessed 14-day adverse clinical events and combined RVD on transthoracic echocardiography (TTE) with cTnI in risk stratification among a broad spectrum of APE patients.

METHODSThe prospective multi-centre trial included 90 patients with confirmed APE from 12 collaborating hospitals. Acute RVD on TTE was diagnosed in the presence of at least 2 of the following: right ventricular dilatation (without hypertrophy), loss of inspiratory collapse of inferior vena cava (IVC), right ventricular (RV) hypokinesis, tricuspid regurgitant jet velocity > 2.8 m/s. The study patients were divided into two groups according to clinical and echocardiographic findings at presentation: Group I: 50 patients with RVD; Group II: 40 patients without RVD.

RESULTSMore than half of the patients (50/90, 55.6%) had RVD. Nearly one third (26/90, 28.9%) of patients had elevated cTnI at presentation and only 4.2% on the fourth day after initial therapy. A multiple Logistic regression model implied RVD, right and left ventricular end-diastolic diameter ratio (RVED/LVED), and cTnI independently predict an adverse 14-day clinical outcome (P < 0.01). Receiver operating characteristics (ROC) curves revealed that the cut-off values of RVED/LVED and cTnI yielding the highest discriminating power were 0.65 and 0.11 ng/ml, respectively. Furthermore, the incidence of an adverse 14-day clinical event in patients with RVD and elevated cTnI was greater (40.7%) than in patients with elevated cTnI or positive RVD alone (0% and 8.3%, respectively) (P < 0.001).

CONCLUSIONSRVD, RVED/LVED, and cTnI are independent predictors of 14-day clinical outcomes. The patients with RVED/LVED greater than 0.65 and cTnI higher than 0.11 ng/ml at presentation possibly have adverse 14-day events. RVD combined with cTnI can identify a subgroup of APE patients with a much more guarded prognosis.

OBJECTIVETo examine the differences in the expression of HSP27 and c-kit between benign prostatic hyperplasia (BPH) and prostatic cancer (PCa) tissues and to analyse the relationship between their expression and BPH and PCa, especially the relationship with the occurrence, development, prognosis and treatment of PCa.

METHODSAn immunohistochemical staining (SP method) for HSP27 and c-kit was undertaken on 40 BPH and 40 PCa tissues samples.

RESULTSConsistent patterns of cytoplasmic staining for HSP27 were seen in all sections of tissue from BPH. The glandular epithelium stained very strongly positively and the stroma stained positively. The staining for HSP27 in PCa tissues was located in the cytoplasm of glandular epithelia, but the expression of HSP27 in PCa was higher than BPH (P < 0.05). The staining for c-kit in BPH tissues was located in the cytoplasm of smooth muscle cells, and in PCa tissues was located in epithelial cells. The expression of c-kit in PCa tissues was lower than BPH (P < 0.05). The expression level of both HSP27 and c-kit were decreased with the development of grade of PCa (P < 0.05); HSP27 was increased with the development of clinical stage of PCa (P < 0.05 ); c-kit was decreased with the development of clinical stage of PCa (P < 0.05).

CONCLUSIONThe expression level of HSP27 and c-kit was highly correlated with the process of the development from BPH to PCa, and also correlated with tumor grades and stages. The expression of HSP27 and c-kit may be used as an important pathological index and may be helpful for the treatment of PCa.
