Objective:To deteat N‐terminal pro B type natriuretic peptide (NT‐pro BNP) and cystatin C (Cys C) con‐tent in Kazak patients with hypertensive heart disease (HHD) complicated heart failure (HF) and analyze the corre‐lation between them .Methods :A total of 100 Kazak HHD patients were divided into hypertension complicated HF group (Complicated HF group , n=50) and pure HHD group (n=50) .Venous blood sample was taken within 24h after hospitalization for measuring serum levels of NT‐proBNP and Cys C ,then they were compared and analyzed between two groups .Results:Compared with pure HHD group ,there were significant rise in serum levels of NT‐proBNP [ (246.53 ± 165.65) ng/L vs .(4568.32 ± 2722.36) ng/L] and Cys C [ (0.82 ± 0.31) mg/L vs .(1.93 ± 2.46) mg/L] in complicated HF group , P< 0.01 both .Spearman correlation analysis indicated that serum NT‐proBNP level was positively correlated with Cys C level in complicated HF group , r=0.961 , P<0.01. Conclusion:In Kazak patients with hypertensive heart disease complicated HF ,serum NT‐proBNP and Cys C levels significantly rise and they significantly positively correlate ,so it suggest there may be slight damaged renal function also .

Objective To explore the infusion chemotherapeutic efficacy and clinical application value for patients with middle-terminal stage esophageal carcinomas.Methods Eighty patients with esophageal squamous carcinoma confirmed with barium meal examination and histopathology were undergone angiography and infusion chemotherapy through catheter in the target artery of the esophageal tumor.Results Complete reliefs were acquired in 26 of 80 patients after the infusion, partial relief in 42, no-change in 11 and progress in 1; the overall effective rate was 85%(68/80). The survival rates was 87.5%(70/80), 38.8%(31/80), 21.3%(17/80), 15%(12/80) at 1, 2, 3 and 5 year intervals respectively. The patients of more than 3 years survival were complete symtomlessness after infusion. The survival rate could be improved significantly with infusion as long as necessary.Conclusions The short-term efficacy with infusion is remarkable and should be the preferable choice, but the medium-long term survival rate is still low. Accomplishment with other therapies is further to be recommeded.

OBJECTIVETo analyze the imaging features of osteopoikilosis and its diagnosis knowledge.
METHODSThe imaging data of 9 patients with osteopoikilosis were analyzed retrospectively, including 6 familial cases and 3 sporadic cases. In 6 familial cases,there were 4 males and 2 females with an average age of 28 years old ranging from 10 to 63 years. Clinical manifestations of 1 familial case were left knee pain and limitation of activity for 3 years, and other 5 cases without clinical manifestation. In 3 sporadic cases, there were 2 males and 1 female with an average age of 33.7 years old ranging from 25 to 44 years. Three sporadic cases had obvious injury history with following up from 6 to 12 months. All imaging results of 9 cases were observed.
RESULTSThe imaging data of 6 familial osteopoikilosis showed the multiple round or oval nodes within bone with clear margins, uniform density, different size. The occurrence of the hyperostotic spots preferentially localized in the epiphyses and metaphyses of the long bones, and carpus and tarus. X-ray features of 3 sporadic osteopoikilosis were similar to that of 6 familial cases and for 6 to 12 months follow-up X-ray features were unchanged.
CONCLUSIONThe imaging features of osteopoikilosis are relatively specific such as the multiple mottling dense focal within bone with clear border and bilateral symmetry, and the focus located on cancellous bone and the diaphyses usually is unaffected. The imaging is a valuable examination for the accurate diagnosis of osteopoikilosis.

OBJECTIVETo determine the expression of Skp2 in different prostate cancer (PCa) cell lines and tissues, and explore its influence on the androgen receptor (AR) signaling pathway and development of castration-resistant prostate cancer (CRPC).
METHODSThe expression levels of Skp2 and AR in different PCa cell lines were detected by Western blot. After knockdown of Skp2 in the C4-2 and 22RV1 cells transfected with shRNA, the expressions of AR and P27 were determined and the activity of ARR3-Luc measured by dual-luciferase reporter gene assay following treatment with dihydrotestosterone (DHT). The expressions of AR and Skp2 in human naïve PCa or CRPC specimens were detected by immunohistochemical staining followed by analysis of their differences and correlation.
RESULTSThe Skp2 protein expression level was significantly higher in the C4-2 or 22RV1 cells than in the LNCaP cells. DHT treatment increased the expression of Skp2 in the C4-2 cells, but knock-down of Skp2 significantly up-regulated the expression of the well-known downstream protein P27 and down-regulated that of AR. Consistently, DHT treatment increased the activity of ARR3-Luc, while knockdown of Skp2 remarkably decreased it in the C4-2 and 22RV1 cells (P < 0.05). In addition, significantly higher expressions of Skp2 and AR were observed in the CRPC than in the naïve specimens (P < 0.05), with a positive correlation between the two proteins (r = 0.658 1, P < 0.05).
CONCLUSIONSkp2 can enhance the expression and transcription activity of the AR protein in CRPC cells or tissues and is promising to be a critical molecular therapeutic target.

Objectives:To investigate the effect of early EN on mucosal structure and absorption function of allograft after living-related small bowel transplantation. Methods:Early enteral nutrition was used.The image analysis,D-xylose absorbtion test and blood culture were used to measure the villus height and area,D-xylose absorption and bacterial translocation in blood. Results:The morphometric examination showed that villus height and villus area were decreased on the 7th postoperative day,began to increase on the 12th day after transplantation and had been the 80% of normal level.The percentage of D-xylose absorption was gradually increased and reached the normal level on the postoperative 38th day.Postoperative blood cultures were always negative. Conclusions:Early EN support can improve the mucosal structure and absorption function of small bowel allograft after living-related small bowel transplantation.

A cellulase high-yield strain was identified and named as Trichoderma longibrachiatum SSL by ITS sequence identification. The endoglucanase1 gene (eg1) encoding endo-l,4-?-D-glucanase I was ampli-fied by RT-PCR method, which including 1386 bp and encoding 461 amino acid. Sequence analysis showed that: This gene has a more 90% homology with the T. longibrachiatum eg1 gene. The eg1 gene encoding the mature peptide was inserted into the Pichia pastoris expression vector pPIC9K, which resulted in construc-tion of the recombinant expression plasmid, pPIC9k-eg1. The pPIC9k-eg1 was then introduced into the host Pichia pastoris GS115. After the induction of methanol, extracellular recombinant endoglucanase I from the supernatant of the recombinant Pichia pastoris strain reached 73 U/mL. A clear strengthening of the protein bands, whose molecular weight is about 58 kD, appeared in the SDS-PAGE.
