Objective To investigate the expressions of transforming growth factor-?1(TGF-?1)and ?-smooth muscle actin(?-SMA)in the lungs of mice with intra-amniotic endotoxin priming and exposed to 60% hyperoxia after born in order to elucidate the possible relationship with bronchopulmonary dysplasia(BPD).MethodsFifty C57 pregnant mice were divided into 2 groups:lipopolysaccharide(LPS,40 ?g/L)group and saline solution group,and then received an intra-amniotic injection of corresponding solution on E15.The neonatal mice of each group were randomized to be set in 60% oxygen exposure or in room air.So there were 4 subgroups,LPS+air,LPS+hyperoxia,saline+air and saline+hyperoxia groups.On days 1,3,7,10 and 14 after birth(8 rats each time point),the lung histological changes was assessed with hematoxylin and eosin(HE)staining for radial alveolar counting(RAC).The expressions of TGF-?1 and ?-SMA proteins were detected by immunohistochemical and immunofluorescence staining,and the expressions of TGF-?1 and ?-SMA mRNA by real-time polymerase chain reaction(RT-PCR).ResultsIn the LPS+hyperoxia group and saline+hyperoxia group,RAC began to decrease on day 3,and then further declined in a time-dependent manner.Compared with saline+hyperoxia group,LPS+hyperoxia group had significantly lower RAC(P

Objective To analyze the features of normal high-frequency ultrasonography of tarsal tunnel. Methods Forty volunteers (20 males and 20 females) were examined with high-frequency ultrasound (12 MHz). The tendons,nerve and blood vessels in tarsal tunnel were observed from short-axis and long-axis views dynamically. The areas of tarsal tunnel and posterior tibial nerve were measured and com-pared between the males and females. Results High-frequency ultrasonography depicted the anatomical structure of tarsal tunnel,and the tendons,nerve and blood vessels presented different sonographic features that were easy to differentiate. The area of tarsal tunnel: male (7.61 ±1.00) cm2,female (6. 61 ± 1. 07) cm2 (P <0. 01). The area of posterior tibial nerve: male (9. 59 ± 0. 75) mm2,female (8.91 ±0.74) mm2(P<0.01). Conclusion High-frequency ultrasonography can clearly show and accurately measure the tarsal tunnel structure. To be familiar with the normal ultrasonographic anatomy of tarsal tunnel will help to improve the efficacy of ultrasound diagnosis of tarsal tunnel abnormalities.

Objective To investigate the relationship between platelet maximum aggregation rate(MAR),platelet thrombocyt-ocrit(PCT),platelet count(PLT),platelet distribution width(PDW)and mean platelet volume(MPV)with the course of acute cere-bral infarction(ACI)to provide the basis for its clinical early diagnosis and treatment.Methods 107 patients with ACI in our hospi-tal were selected and divided into the great infarction group(infarction size >10 cm3 ),middle infarction group(infarction size 4-10 cm3 )and small infarction group(infarction size<4 cm3 )according to the infarction lesion size by head CT or MRI and the infarction volume calculated by the Pullicino formula(length×width×layer number/2),40 healthy individuals were selected as the healthy control group.MAR,PLT,PDW,MPV and PCT were detected before and after the induction by PLR-06.Results (1 )Compared with the control group,PLT,PCT,PDW and MPV before the induction by PLR-06 in the great infarction group were obviously in-creased(P <0.01);PLT,PCT,PDW and MPV in the middle and small infarction groups were increased(P <0.05).(2)Compared with the control group,MAR after the induction by PLR-06 in each infarction group was increased(P <0.05);PLT had no statisti-cal difference among the groups(P >0.05 );PCT,PDW and MPV in the great and middle infarction groups were increased(P <0.05);PCT,PDW and MPV in the small infarction group had no statistical differences(P >0.05).Conclusion The change of the platelet aggregation rate,number and volume is closely related with the occurrence and development of ACI,monitoring their change has important clinical significance to prevention and treat ACI.

Objective To analyze the ultrasonic features of thyroid microcarcinoma (TMC) and the causes of misdiagnosis. Methods The ultrasonic features including shape, margin, echogenecity, microcalcification, vascularity and lymphadenopathy were analyzed retrospectively in 26 pathologically-proven TMC patients. Results In 26 cases, 11 cases were diagnosed correctly before operation (11/26, 42.31%), 12 cases were misdiagnosed (12/26, 46.15%) as adenoma or benign nodule, and 3 cases were missed diagnosed (3/26, 11.54%). Among the 23 cases detected on ultrasound, 21 cases were solid and hypoechoic (21/23, 91.30%);19 cases were ill-defined (19/23, 82.61%);12 cases were taller than wide in shape (12/23, 52.17%); 14 cases had microcalcification (14/23, 60.87%); 7 cases showed central or peripheral blood flow signals (7/23,30.43%) with arterial resistance index>0.70 in 3 lesions and<0.70 in 4 lesions. Conclusions Several ultrasonographic features are helpful in identiifcation of TMC, including hypo/iso-echogenecity, ill-deifned margin, taller-than-wide shape, microcalciifcation, arterial signals with high resistance index, and abnormal lymphadenopathy. Moreover, for cases with multiple lesions, to the potential co-existence of benign and malignant lesions should be considered.

Objective To investigate the effect of human cytomegalovirus (HCMV) on proliferation of colony forming unit T-lymphocyte (CFU -TL)and its interference methods. Methods Normal CFU - TL culture was used as blank control. Normal CFU- TL culture system plus inactivated HCMV fluid as inactivated HCMV control. The dilution of 1:10,1:100,1:1000 were added into CFU -TL colonies culture system directly as infected group. Astragalus (AMI) and ganciclovir(GCV) were added into culture system with HCMV dilution of 1:10 as experimental group. By methylcellulose semi-solid culture, different concentrations of HCMV - AD1699 affect CFU-TL and interfered by astragalus AMI, GCV. CFU - TL were surveyed. The effect of HCMV on CFU-TL proliferation was measured by MTT; HCMV-AD169 DNA in CFU-TL was found by PCR. Results 1. Compared with control group, the numbers of CFU -TL in the HCMV infection groups decreased significantly(P

Objective To assess the effectiveness of the clinical pathway for the treatment of advanced schistosomiasis he-patic fibrosis. Methods The duration of hospital stay,gross hospitalization expense,individual-paid expense,interior diame-ter of portal vein,levels of four serum hepatic fibrosis-related parameters(PIIIP,CIV,HA,and LN),and activities of ALT, AST andγ-GT were assessed and compared between the advanced schistosomiasis patients receiving the clinical pathway and ones receiving non-clinical pathway. Results There were 142 advanced schistosomiasis patients with hepatic fibrosis receiving the clinical pathway of anti-hepatic fibrosis. Compared with the patients receiving non-clinical pathway ,the gross hospitalization expenses reduced by 11.2%(t=6.310,P<0.05),and the individual-paid expenses reduced by 16.1%(t=4.326,P<0.05). The mean HA level was twice higher than the normal range,with a positive rising from 70.4%to 83.1%,and the abnormal rates of CIV andγ-GT were 64.1%and 28.9%respectively. Conclusions The clinical pathway can drastically reduce the treatment expenses in advanced schistosomiasis patients with hepatic fibrosis. However,the patients have a trend towards the persistent disease progression. Therefore,the researches of more effective therapeutic methods for advanced schistosomiasis hepatic fibro-sis are urgently needed.
