Objective To investigate the thyroid hormone changes and their relationship with the state of severity in critically ill patients. Methods Ninety-two patients with no thyroidal illness syndrome admitted to the ICU from January ,2009 to December,2009 were enrolled in this study. The common situations and the score of acute physiology and chronic health evaluation Ⅱ were assessed on addmission. We measured the thyroid hormone levels on the day after admission and analysed whether thyroid hormone levels were related to disease severity. Results The thyroid hormone levels in septic shock group [TT3 (1.16 ± 0.24) nmol/L, TT4 (68.93 ± 24.11) nmol/L, FT3 (3.76 ± 0.21) prnol/L, FT4 (16.40 ± 2.74) pmol/L, TSH (1.58 ± 1.01) mU/L] were significantly lower than those in non-septic shock [TT3 (1.50 ± 0.25) nmol/L, TT4 (91.70 ± 21.90) nmol/L, FT3 (4.24 ± 0.45) pmol/L, FT4(17.98 ± 3.28) pmol/L, TSH (2.43 ± 2.76) mU/L] (P ＜ 0.05). The serum thyroid hormone levels of free triiodothyronine (FT3) ,free thyroxine (FT4) were related to the score of APACHE Ⅱ in septic shock(P ＜ 0.05).Conclusions The levels of thyroid hormone were significantly lower in critically ill patients than the control group and had positive correlation with the disease severity.

ObjectiveTo study the possibility of differentiation of human umbilical cord mesenchymal stem cells(HUCMSCs) into human male germ cells,and to explore a new source of cells for the treatement of male infertility.MethodsHUCMSCs were transplanted into the seminiferous tubules of the testis of infertile mice by microinjection.The survival rate,migration and germ cell markers of HUCMSCs in the mice testis were detected via immunohistochemistry,immunofluorescence and confocal laser scanning. ResultsHUCMSCs can survive in the mice testis for at least 120 days,and they can migrate from the lumens to the basement membrane.Immunofluorescence showed that HUCMSCs can further differentiate in the mice testicular environment,and express the germ cell marker.ConclusionsHUCMSCs can survive,migrate and differentiate into early male germ cell-like cells in the infertility mice testis after transplantation.

Rheumatoid diseases (RD) are a group of diseases affecting bones,joints,and the surrounding soft tissues,such as muscle,synovial membrane,tendons,fascia,nervus.The etiology and pathogenesis are complicated.Since most RD are systemic diseases,traditional imaging techniques have limited value for the diagnosis and treatment monitoring of RD.18F-FDG PET/CT can display morphologic and metabolic information simultaneously,and is considered as a potential tool for the diagnosis of RD.This review summarizes the application of 18F-FDG PET/CT in RD,such as systemic vasculitis,relapsing polychondritis and rheumatoid arthritis.

Objective To study the antagonistic effects of selenium and germanium (Se-Ge) in combination on the kidney damage induced by fluoride in rats.Methods Fifty SD rats were randomly divided into 5 groups,the control group (distilled water),fluoride group (NaF,100 mg/L),fluoride plus selenium group (100 mg/L NaF + 20 mg/L Na2SeO3),fluoride plus germanium group(100 mg/L NaF + 2 000 mg/L Ge-132) and fluoride plus selenium and germanium group(100 mg/L NaF+ 20 mg/L Na2SeO3+ 2 000 mg/L Ge-132),10 in each group (males and females were in the same number).The administration was conducted through gavage for 90 days.After 90 days of treatment,the kidneys were collected and the organ coefficients were calculated,MDA contents,SOD and GSH-Px activities in the tissue were determined and the histopathological examination was done.Results Fluoride decreased the organ coefficient of kidney,Se and/or Ge showed an obvious antagonism to fluoride,administration in combination was more efficient than singly.Na2SeO3 and/or Ge-132 had an antagonistic effect to fluoride in the increase of lipid peroxide(MDA) and decrease of the activity of glutathione peroxidase(GSH-Px),superoxide dismutase(SOD).Na2SeO3 and/or Ge132 could prevent the pathologic damage caused by fluoride in the kidneys.Conclusion Na2SeO3 and Ge-132 in combination has an obvious antagonistic effect on fluoride-induced kidney damage.

Objective To investigate the impact of percutaneous coronary interventional (PCI) on the inflammatory indices and postoperative vascular restenosis.Methods This study involved 90 patients undergoing PCI procedures for Coronary artery disease (CAD) compromising a single coronary artery.Fourty healthy individuals with normal findings by coronary angiography were selected as the control group.Before and after PCI or coronary angiography,plasma hs-CRP and IL-6 were measured in all the subjects by immunonephelometry and enzyme-linked immunosorbant assay (ELISA),respectively.Results (1) In the CAD patients,the plasma hs-CRP level was significantly elevated after PCI as compared with the preoperative level((18.69 ±5.14) mg/L vs (14.45 ± 4.32) mg/L,t =1.42,P ＜ 0.01),whereas in the control group,the hs-CRP level underwent no significant changes after coronary angiography((13.59 ±5.99) mg/L vs(12.46 ±5.35) mg/L,t =1.25,P ＞ 0.05).(2) PCI procedures also resulted in significant elevation of plasma IL-6 level in the CAD patients((1.87±0.45) pg/L vs (1.35 ±0.39) pg/L,t =1.33,P＜0.01),but in the control group,IL-6 showed no significant variation after coronary angiography ((1.32 ± 0.41) pg/L vs (1.21 ± 0.38)pg/L,t =1.16,P ＞ 0.05).We observed significant difference of hs-CRP and IL-6 levels between the CAD patient group and the control group (t =4.96,6.61 respectively,P ＜ 0.01).Conclusion Plasma hs-CRP and IL-6 are elevated in CAD patients following PCI procedures.But the roles of elevated hs-CRP and IL-6 in the vascular restenosis following the procedures need further investigation.

A total of 60 patients with an acute attack of asthma were studied.On presentation,fractional exhaled nitric oxide (FeNO) and the serum concentrations of procalcitonin (PCT) and C-reactive protein (CRP) were measured.And sputum culture was also performed.The patients were re-evaluated while returning to their clinical remission states.They were classified into 2 groups:patients with bacterial infection (group A) and those with nonbacterial infection (group B).The levels of FeNO were significantly higher in patients with acute exacerbation than those in remission.No difference existed between groups A and B ( P ＞ 0.05 ).The levels of PCT and CRP of group A with acute exacerbation were significantly higher than those of group B( all P ＜0.05).While in remission,the levels of PCT and CRP decreased significantly in group A ( P ＜ 0.05 ) ; But compared with exacerbation,the levels of PCT and CRP showed no change in group B (P ＞0.05).And no differences existed between two groups while in remission (P ＞ 0.05 ).An elevation of FeNO indicates the acute exacerbation of asthma.And the increased serum levels of PCT and CRP are associated with bacterial infection.

Objective To investigate the pathologic foundation,clinical characteristics and CT features of microscopic polyangiitis(MPA)with lung involvement.Methods Clinical data of 6 patients of MPA with lung involvement in 2003-2006 were retrospectively analyzed.Results The types of lung imaging manifestations as the followings:(1)Mutiple flaky shadow in both lung in 3 cases.(2)Ground-glass shadow in 1 case.(3)Disseminated interstitial lung involvement in 2 cases.The main respiratory symptom was haemoptysis except cough and expectoration.Renal damaging often occurred besides the lung.Six cases with positive antineutrophil cytoplasmic antibody(ANCA)and 5 cases with positive P-ANCA/MPO-ANCA were found in laboratory examination.Conclusions The CT manifestations of MPA with lung involvement have no characteristic features.Clinical characteristics and laboratory examination can help to understand and diagnose MPA with lung involvement early.
