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.

OBJECTIVETo explore the effect of Yixintai Granule (YG) on mRNA and protein expression levels of AQP2 in renal medulla of chronic heart failure (CHF) rabbits.
METHODSCHF rat model was established by ear marginal vein injection of adriamycin. Successfully modeled rabbits were divided into the model group, the high (8.4 g/kg), middle (4.2 g/kg), and low dose (2.1 g/kg) YG group, and the Furosemide group (2 mg/kg). Besides, a normal control group was set up. Equal volume of physiological saline was administered to rabbits of the model group and the normal control group by gastrogavage. YG at different doses was administered to rabbits of the 3 YG groups by gastrogavage. The intervention lasted for 4 weeks, once per day. After treatment the urine volume and pathomorphological changes of renal medulla tissue were observed. mRNA and its protein expression levels of AQP2 were detected.
RESULTSCompared with the normal control group, the urine volume decreased significantly, mRNA and protein expression levels of renal medulla AQP2 increased significantly in the model group (all P < 0.01). Compared with the model group, the urine volume increased significantly, and mRNA and protein expression levels of renal medulla AQP2 decreased significantly in all medicated groups (all P < 0.01). Compared with the low dose YG group, the urine volume significantly increased and the mRNA expression level of renal medulla AQP2 significantly decreased in the middle and high dose YG groups (all P < 0.01). The expression level of AQP2 protein significantly decreased in the high dose YG group (P < 0.01). Pathological changes of the renal medulla was the most obviously seen in the model group. But they were alleviated to various degrees in all medicated groups. They were more obviously attenuated in the middle and high dose YG groups.
CONCLUSIONYG could improve CHF possibly through down-regulating mRNA and protein expression levels of AQP2 in renal medulla, and elevating the urine volume.

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 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.

OBJECTIVETo observe the curative effect of Shenyanning (SYN) on non-nephrotic syndrome IgA nephropathy (IgAN).
METHODSSeventy primary IgAN patients were equally randomized into two groups, the treatment group and the control group, they were orally treated with SYN Decoction (one dose per day) and Losartan (50 mg per day) respectively for 1 year. Efficacy of treatment, Chinese medicine syndrome scores, end-point events occurrence as well as changes of related laboratory indices were observed.
RESULTSThe total effective rate in the treatment group was obviously higher than that in the control group (77.1% vs. 54.3%, P < 0.05). After treatment, the Chinese medicine syndrome scores, urinary protein and urinary red-cell count reduced significantly in the treatment group (P < 0.05 or P < 0.01) and showed significant difference as compared with those in the control group (P < 0.05 or P < 0.01); while the endogenous creatinine clearance was changed insignificantly in both groups. Beside, the occurrence of end-point events in the treatment group was slightly lower than that in the control group, though showed no statistical difference between them.
CONCLUSIONThe curative effect of SYN in treating IgAN was obviously better than that of simple Western medicine.
