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.

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.

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.

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.

Objective To evaluate the functions of the left atrium using two-dimensional strain（2DS）echocardiography and left atrium volume index（LAVI）in the patients with hypertrophic cardiomyopathy（HCM）and explore its clinical value.Methods There were 37 patients with HCM and 35 healthy subjects enrolled in our study.Left atrial passive ejection fraction（LAPEF）and left atrial active ejection fraction（LAAEF）were calculated using Simpson＇s method.The analysis for atrial longitudinal peak systolic strain（S）,peak systolic stain rate（SRs）,peak early diastolic stain rate（SRe）and peak late diastolic strain rate（SRa）on the interatrial septum and the lateral wall of the left atrium were performed using 2DS echocardiography.Results LAPEF and LAAEF significantly decreased compared with those in the control group（P 0.05,P 0.01）.LAVI in HCM group increased compared with that of the control group（P 0.01）.S,SRs,SRe and SRa of the interatrial septum and the lateral wall were lower in patients with HCM than those in control group（P 0.05）.LAVI was negatively correlated to 2DS（r =0.73,P 0.05）.Conclusion The left atrial functions decreased in patients with HCM.2DS and LAVI are readily obtained parameters that provide unique data about global and segmental atrial functions.

Objective To analyze the current status of neonatal resuscitation in medical institutions in China.Methods With the number of obstetric beds as the inclusion criteria,the survey was conducted in 163 medical institutions randomly selected in 11 provinces (including 51 tertiary hospitals,88 secondary hospitals and 24 primary hospitals) from October 1 to December 31 in 2011.The mail-questionnaire was sent to collect information about system establishment,personnel training,neonatal resuscitation equipment etc.Statistical data was analyzed by t-test,variance analysis and Chi-square test.Results The incidence of neonatal asphyxia among live birth babies was 2.15％ (3328/154 853) in tertiary hospitals,1.41％ (2829/200 731) in secondary hospitals and 1.50％ (701/46 695) in primary hospitals (x2=298.559,P＜0.01).The mortality rate during delivery was 0.41‰ (63/154 853),0.24‰ (48/200 731) and 0.60‰ (28/46 695) at the three different level hospitals,respectively (x2=16.993,P＜0.01).The mortality rate within 24 hours after delivery was 0.42‰ (65/154 853) in tertiary hospitals,0.24‰ (49/200 731) in secondary hospitals and 0.62‰ (29/46 695) in primary hospitals (x2 18.075,P＜0.01).About 86.5％ (141/163) of the included hospitals maintained routine neonatal resuscitation trainings,but only 73.0％ (119/163) applied resuscitation training equipments during the trainings.The outfit rate of basic neonatal resuscitation equipments (such as neonatal laryngoscope,radiant heater) was high in most hospitals,but the outfit rate of equipments recommended by the new guideline (such as umbilical venous catheter,T piece and oxygen saturation meter) was low.For example,the outfit rate of umbilical venous catheter was 23.5％ (12/51),10.2％ (9/88) and 4.2％ (1/24) in tertiary,secondary and primary hospitals respectively (x2 =6.992,P ＜ 0.05).47.9％ (78/163) of the hospitals had set up neonatal intensive care unit,with the proportion in tertiary,secondary and primary hospitals being 80.4％ (41/51),34.1％ (30/88) and 27.2％ (7/24),respectively (x2=31.677,P＜0.01).Most of the hospitals (80.4％,131/163) could ensure the pediatricians being presented in the delivery room for high risk women,and the proportion was 94.1％ (48/51),79.5％ (70/88) and 54.2％ (13/24) in tertiary,secondary and primary hospitals,respectively (x2 =16.591,P＜0.01).There were 88.3％ (144/163) of the hospitals had routine neonatal resuscitation case audit,with the proportion in the three different level hospitals being 94.1％ (48/51),92.0％ (81/88) and 62.5％ (15/24),respectively (x2 =18.388,P＜0.01).Conclusions Strengthen the training,equipment and system establishment in primary medical institutions is conducive to promote neonatal resuscitation.
