Objective To explore the diagnosis value of cystatin C(Cyst-C) level on the renal function early impairment of Henoch-Schonlein purpura(HSP).Methods The selected serum creatinine(SCr) normal 45 sufferers,with measured their urine routine analysis,and the same time did serum Cyst-C.Compared with 30 healthy children of serum Cyst-C.Results The levels of serum Cyst-C in HSP were definitely higher than those in healthy group,and the differences were together with its signifincance(P

Objective To detect genetic alterations in pleomorphic xanthoastrocytoma (PXA), and to investigate the mechanism of development of this neoplasm. Methods Three patients with PXA were studied. Comparative genomic hybridization (CGH) was performed to study chromosomal imbalances in PXA. Using immunohistochemical analysis, the expression of EGFR was detected in PXA. Results Using CGH analysis, genetic imbalance was detected on at least one chromosome for each case. One patient revealed multiple genetic alterations, including gains of 2p14-pter, 4p15-pter, 7p21-qter, 11q24-qter, 12 and 15q14-qter,as well as losses of 8p11.2-pter, 9p11-p23, 10p12-pter, and 13q14-qter. This patient experienced tumor recurrence and died one year later. Gain on Chromosome 7 and loss on Chromosome 8p were demonstrated in 2 of the 3 patients. Immunohistochemically, no EGFR positive reaction was found in all cases. Conclusion Detection of genetic alterations is very important in understanding the pathogenesis of PXA.

Objective To investigate the value of thyroid transcription factor-1(TTF-1) in the diagnosis and biological behavior assessment of hepatocellular carcinoma (HCC). Methods Thirty liver specimens obtained from benign lesions were analysed, among which 25 were hepatic cirrhosis and inflammatory diseases, and the other 5 were adenomas. And there were 176 specimens of liver tumors, among which 142 were HCC (well differentiated, n=12; moderately differentiated, n=57; poorly differentiated, n=73), 17 were intrahepatic cholangiocellular carcinoma (ICC) and the other 17 were liver metastatic carcinoma (MC). The expression of TTF-1 was examined immunohistochemically in the above tissues, and the difference in expression of TTF-1 among different tissues was examined by Fisher's exact test, Kruskal-Wallis test and Spearman rank correlation analysis. Results TTF-1 was significantly expressed in the cytoplasms of all the hepatocytes besides tumors and liver benign lesions. The expression rate of TTF-1 in HCC was 78.9% (112/142), however, TTF-1 was negatively expressed in ICC and MC(P

Objective To study the effect of sevoflurane pretreatment or aftertreatment on intrapulmonary shunt for patients with one lung ventilation(OLV)during thoracic surgical procedures .Methods 80 ASA I or II patients underwent thoracic surgery with OLV were randomly divided into four groups(n= 20 for each):(1)Propofol group(group P);(2)Sevoflurane pretreatment group(group S1);(3)Sevoflurane aftertreatment group(group S2);(3)Sevoflurane whole-treatment group(group S3) .Blood sam-ples were taken from radial artery and right atrial blood before induction of anesthesia(baseline T .0) ,before OLV(sevoflurane pre-treatment 30 min ,T1) ,after OLV 30 ,60 min and before the end of OLV(T2-T4)and after the end of OLV(T5)for measurement of blood gases and calculation of Qs/Qt .The indexs of hemodynamics and relative clinical data were recorded .Results Arterial oxy-gen pressure of the four groups for OLV significantly reduced ,when compared with double lung ventilation(P<0 .05) ,but there was no significant difference among the four groups(P>0 .05) .Intrapulmonary shunt of the four groups for OLV significantly in-creased ,when compared with double lung ventilation(P<0 .05) ,but intrapulmonary shunt of S1 ,S2 and S3 groups significantly de-creased ,when compared with P group ,and there was no significant difference for S1 ,S2 and S3 groups(P> 0 .05) .Conclusion Sevoflurane can decrease intrapulmonary shunt for patients during OLV ,but there is no significant difference for pretreatment or af-tertreatment or whole treatment and do not increase arterial oxygen pressure .

Aim To study clinical efficacy of valsartan,in comparison with amlodipine, in hypertentive patients with left ventricular hypertrophy. Methods 65 hypertentive patients with left ventricular hypertrophy is divided into two groups, with 33 cases in valsartan group and 32 cases in amlodipine group Valsartan 80～160mg and amlodipine 5～ 10 mg were taken by the patients in the two groups for 6 months respectively. 24 h ambulatory blood pressure monitoring ( 24 h ABPM) and color echocardiography were performed in the two groups before and after treatment. Results The parameters of 24 h ABPM ( 24 h SBP? 24 h DBP?dSBP?dDBP?nSBP?nDBP) and color echocardiography (IVST?PWT?LVMI)after treatment in the two groups were significant decreased compared with those before treatment respectively (P0.05). Conclusion Valsartan can lower significantly the blood pressure level and make left ventricular hypertrophy remarkably dispelled in hypertensive patients with left ventricular hypertrophy and has the effect similar to that of amlodipine.
