Objective To explore the expressions and significance of Yes-associated protein (YAP) and large tumor suppressor gene 1 ( LATS1 ) in renal clear cell carcinoma (RCCC).Methods There are 30 cases of RCCC,15 males and 15 females.The median age was 63 (36 - 77) years.There were 17 cases of stage Ⅰ - Ⅱ,13 cases of stage Ⅲ - Ⅳ.There were 8 cases well differentiated,13 cases moderately differentiated and 9 cases low differentiated.The expressions of YAP,LATS1 mRNA and proteins in 30 cases of RCCC and normal renal tissues were tested by RT-PCR and immunohistochemistry,and were analyzed with clinical data.ResultsThe expression level of YAP mRNA in RCCC was higher than that in normal renal tissues (0.569 ± 0.066 vs 0.515 ±0.068,P =0.003 ),and the level of LATS1 mRNA in RCCC was lower than that in normal renal tissues (0.454 ± 0.115 vs 0.514 ± 0.093,P =0.029 ).Thepositive rate of YAP proteins in RCCC was obviously higher than that in normal renal tissues (63.3％ vs 33.3％,P =0.020),and the positive rate of LATS1 proteins in RCCC was lower than that in normal renal tissues (46.7％ vs 76.7％,P =0.017).The positive rate of YAP proteins was 33.3％ in well differentiated tissues,61.5％ in moderately differentiated tissues and 88.9％ in low differentiated tissues ( P =0.018),and the positive rate of LATS1 proteins was 75.0％ in well differentiated tissues,53.8％ in moderately differentiated tissues and 11.1％ in low differentiated tissues (P =0.024).The positive rate of YAP proteins was 47.1％ in stage Ⅰ - Ⅱ and 84.6％ in stage Ⅲ - Ⅳ ( P =0.034 ),and the positive rate of LATS1 proteins was 64.7％ in stage Ⅰ - Ⅱ,23.1％ in stage Ⅲ - Ⅳ ( P =0.024 ).ConclusionYAP and LATS1 play important roles in the development of renal clear carcinoma,and may become new targets in the treatment of RCCC.

Objective:To study the relationship between serum soluble intercellular adhesion molecule-1(sICAM-1) and vascular endothelial growth factor(VEGF), placenta growth factor(PLGF), vascular endothelial growth factor receptor 1(VEGFR1, Flt-1), soluble vascular endothelial growth factor receptor 1(sVEGFR1, sFlt-1) mRNA expression in placenta tissue of preeclampsia(PE). Methods: The serum level of sICAM-1 was measured by enzyme-linked immunosorbent assay and gene expression of placenta tissue was detected by quantitative reverse transcriptase-polymerase chain reaction(RT-PCR). Results:(1)The average serum level of sICAM-1 was(218.45±29.93) μg/L in PE group compared with (168.84±19.39) μg/L in controls(P < 0.01).(2)The mRNA expressions of VEGF, PLGF, Flt-1 and sFlt-1 were increased in placenta of PE than those in controls (P < 0.01).(3)There was a positive correlation between the serum level of sICAM-1 and the sFlt-1 mRNA expression in placenta tissue(r = 0.90, P < 0.01). Conclusion: The serum level of sICAM was increased in the patients with PE. The expressions of VEGF, PLGF, Flt-1 and sFlt-1mRNA were increased remarkably in the placenta tissue of palients with PE,especial for sFlt-1. The remarkable increase for expression of sFlt-1mRNA may contribute to endothelial dysfunction, hypertension and proteinuria.

Objective To observe the changes of adrenal cortical function in children with growth hormone deficiency before and after treatment with recombinant human growth hormone. Methods Seventy-two children diagnosed with GHD who received rhGH treatment for no less than 6 month were included, among whom there were 32 children who were accompanied with adrenal cortical hormone (ACTH) deficiency. The changes of fasting plasma cortisol (COR) and ACTH levels before and 3 and 6 months after treatment with rhGH were retrospectively analyzed. Results Thirty-two children with ACTH deficiency were treated with rhGH after COR level reached normal by the supplementing exogenous hydrocortisone. There was negative correlation between COR level before treatment and the HC dose that make the COR reach normal lowest limit level (r?=?-0.899, P??0.05). The level of COR was obviously decreased after treatment with rhGH, and there was statistical difference compared with that before treatment (P?

BACKGROUND:Previous studies have shown that, curcumin plays a crucial role on the inflammation in cells caused by oxidative stress.
OBJECTIVE:To elucidate the biological effect and mechanism of curcumin in the pathological inflammation reaction in vascular endothelial cells.
METHODHuman vascular endothelial cells were taken as the cellmodels. Tumor necrosis factor (10μg/L) treatment was used to induce the inflammation of cells. Curcumin (0, 50, 100μg/L) treatment for 24 hours was used to intervene the cells. The intercellular hyperpermeability of the vascular endothelial cellmonolayers was examined by HRP-conjugated bovine serum albumin, and intercellular filamentous actin stress fiber formation was examined by rhodamin-phal oidin staining. ELISA assay was used to detect the secretion of interleukin-1βin vascular endothelial cells. Immunoflurensece staining was applied to investigate the expression and translocalization of nuclear factor-κB. Western blot analysis reflected the expression of NRLP3 and caspase-1.
RESULTS AND CONCLUSION:HRP-bovine serum albumin detection results showed that, curcumin inhibited the intercellular hyperpermeability of the vascular endothelial cellmonolayers and the formation of robust intercellular filamentous actin in a dose-dependent manner. ELISA assay showed that curcumin protected vascular endothelial cells against tumor necrotic factor-α-induced interleukin-1βsecretion in a dose-dependent manner. Meanwhile, the nuclear factor-κB expression was increased and the translocation of nuclear factor-κB into the nuclei was obviously seen in vascular endothelial cells induced by tumor necrosis factor-α, but the translocation was not changed in 100μg/L curcumin-treated cells. Furthermore, western blot analysis revealed that the expression of NRLP3 and caspase-1 were inhibited in curcumin-treated cells. Curcumin can inhibit tumor necrosis factor-α-induced activation of inflammasome and secretion of interleukin-1βin vascular endothelial cells by down-regulating the expression of nuclear factor-κB, thus prevent pathological inflammatory injury in cells.

BACKGROUND:Stem cel s can be induced to differentiate into dopaminergic neurons in vivo and in vitro, which provides a theoretical basis for stem cel transplantation in the treatment of Parkinson’s disease
OBJECTIVE:To explore the feasibility and mechanism of intracerebral transplantation of umbilical cord blood mesenchymal stem cel s for treatment of Parkinson’s disease rats.
METHODS:Intracerebral injection of 6-hydroxydopamine was used to make Parkinson’s disease models in SD rats. Twenty-two model rats were randomized into cel transplantation group (n=12) and control group (n=10) and respectively injected intracerebral y with umbilical cord blood mesenchymal stem cel suspension and PBS. At 1-8 weeks after cel transplantation, intra-abdominal injection of apomorphine was performed every week to observe the rotation behaviors of rats;at the 2nd and 8th weeks, rat’s striatum and substantia nigra were taken for immunohistochemistry staining.
RESULTS AND CONCLUSION:The rotation behaviors were gradual y decreased with time in the cel transplantation, but had no changes in the control group. At 3-8 weeks after transplantation, there were significant differences in the rotation behaviors between the two groups (P<0.05). At 2 weeks after transplantation, tyrosine hydroxylase-positive cel s were found within and around the striatum of the cel transplantation group;but there were no exogenous cel s in the control group. At 8 weeks after transplantation, there were stil active cel s and tyrosine hydroxylase-positive cel s in the striatum of cel transplantation group, and there was no tyrosine hydroxylase expression in the striatum of the control group. These findings suggest that transplanted umbilical cord blood mesenchymal stem cel s can survive in the brain that are positive for tyrosine hydroxylase, which can improve the behavior abnormalities of Parkinson’s disease rats.
