Methods The expression of MT and Ki 67 were assayed by means of immunohistochemical technique in RCC tissues and normal renal tissues.DNA content and S phase fraction(SPF) were measured by flow cytometry(FCM). Results The positive expression rates of MT in RCC tissues and normal renal tissues were 52.5%,78.9% respectively( P

Objective To determine the value of vascular indication of sexual excitation response (VISER) in the diagnosis of erectile dysfunction (ED). Methods Fifty three cases of ED underwent PGE1 intracavernous injection,VISER and color duplex ultrasonography.The comparison of the results was performed. Results Forty three cases were in Porst Grade 3, whose average cavernous pressure and carvenous pressure index were 144.29 mmHg and 1.24,respectively.Of them,42 cases were of normal penile vascular function,the remaining one was of venous ED;10 cases were in Porst Grade 2, whose average cavernous pressure and carvenous pressure index were 87.76 mmHg and 0.81,respectively.There were significant differences in the average cavernous pressure and carvenous pressure index between the two groups ( P

To explore the related risk factors and outcome in pregnancy- induced hypertension patients with Ⅲ phase of retinopathy.
●METHODS: A total of 105 pregnancy - induced hypertension patients with Ⅲ phase of retinopathy in our hospital from Januany 2012 to December 2013 were enrolled. Clinical date of them were collected to analyze.
●RESULTS: The occurrence of pregnancy - induced hypertension patients with Ⅲ phase of retinopathy were positively correlated with the course of the disease, blood pressure, proteinuria, and it was higher occurred in cold winter and spring, timely termination of pregnancy and appropriate hormone therapy can promote the recovery of vision, and improve outcomes of pregnancy.
●CONCLUSlON: The occurrence of pregnancy - induced hypertension patients with Ⅲ phase of retinopathy associated with season and disease severity. Timely treatment can restore normal vision, improve maternal and neonatal prognosis. Routine examination of fundus examination should be used as the pregnancy induced hypertension syndrome.

Objective: To explore the core composition and compatibility features of Ershiwuwei Songshi pills in the treatment of liver disease, in order to provide ideas and methods for the optimization of Tibetan medicine prescriptions and the creation of new medicine. Methods: In this study, I checked common prescriptions for the treatment of liver diseases from the Tibetan Medical Classics, such as Four Medical Classics, Xin Xiu Jing Zhu Ben Cao, etc., summarizing the flavor, nature and efficacy of the 25 herbs in Ershiwuwei Songshi pill, and analyzing the compatibility features of flavor and of nature and efficacy of the 25 herbs in Ershiwuwei Songshi pill. And I also sorted out 21 common prescriptions for the treatment of liver diseases in the Tibetan Medical formula, counting and analyzing the using frequency of the ingredient medicine of Ershiwuwei Songshi pill in the 21 Tibetan medical formula for the treatment of liver and the compatibility frequency. Conclusion: The results show that Ershiwuwei Songshi pills are composed of a heat clearing formula, mainly for the treatment of heat liver diseases.

OBJECTIVETo investigate contrast-enhanced ultrasound imaging features of diabetic foot ulcers.

METHODSSixteen patients with diabetic foot ulcers underwent conventional and contrast-enhanced ultrasound examinations, and the features of contrast-enhanced ultrasound imaging were analyzed. Pathological examination was also carried out in some cases.

RESULTSContrast-enhanced ultrasound showed slow enhancement in the artery phase in the 16 ulcers after administration of SonoVue. The mean time of initial enhancement was 30.02 ± 2.35 s, and the mean time for the occurrence of peak enhancement was 37.54 ± 4.13 s. In 5 cases a homogeneous enhancement pattern was clearly displayed, and in the other 11 cases, a pattern of homogenous peripheral enhancement with non-enhanced patches within the ulcers was found. Contrast-enhanced ultrasound showed a greater ulcerous area than conventional ultrasound.

CONCLUSIONContrast-enhanced ultrasound is a valuable means for evaluating the ulcerous area and the treatment efficacy for diabetic foot ulcers.

Molecular genetic map is a fundamental organizational tool for genomic research. However, a genetic linkage map for Bupleurum chinense DC. has not been developed. In this study, with the theory of pseudo-testcross, 96 F1 plants from an intraspecific cross of B. chinense were used as mapping populations. Twenty eight ISSR (inter-simple sequence repeat) primers and 44 SSR (simple sequence repeat) primers were used to detect the polymorphisms between the parental plants, and of them, 28 ISSRs and 14 SSRs were selected to analyze the F1 populations. The map consisted of 13 linkage groups which included 80 (72 ISSRs and 8 SSRs) loci, and covered 2 633.9 cM with an average density of 33.4 cM. All 13 linkage groups consisted of 2-31 loci ranging in length from 15.4-1295.7 cM. This map will provide a basis for studies on gene mapping, map-based cloning and maker-assisted selection of important traits in B. chinense.

OBJECTIVETo investigate the effect of SHIP gene mutation on the cell cycle and its related gene expression in K562 cells.

METHODSThe recombined green fluorescent protein (GFP) containing FIV-SHIP gene was transfected into K562 cells. The transfection efficiency and cell cycle of K562/SHIP were assessed by flow cytometry (FCM). The proliferation of K562 cells was detected by MTT assay, the mRNA levels of SHIP by real-time fluorescent relative-quantification reverse transcriptional PCR (FQ-PCR), and the protein levels of SHIP, Cyclin D1, p21(WAF1/CIPI) and p27(KIP1) by Western blot.

RESULTSWild type SHIP inhibited K562 cell proliferation and caused a G(0)/G(1) arrest \[(34.2 +/- 7.8)% vs (0.7 +/- 8.3)% (P < 0.01)\]; while the point mutation of SHIP gene did not show such effect. Western blot results showed that the Akt phosphorylation and cyclin D1 expression was significantly decreased (P < 0.01), and the expression of p27(KIP1) and p21(WAF1/CIPI) increased. Site-directed mutation of SHIP gene SH2 domain (TTC-->CTC, Phe-->Leu) did not influence the Akt phosphorylation and cyclins (P > 0.05).

CONCLUSION(1) wtSHIP gene can down-regulate Akt phosphorylation and result in inhibition of cyclin D1 expression, up-regulating p27(KIP1) and p21(WAF1/CIPI) expression, finally leading to the reduction of K562 cell proliferation, and inducing G(0)/G(1) phase arrest. (2) SHIP gene suppresses the proliferation of K562, being dependent on its intact structure and function.
