Objective To investigate the effect of Niaochangshu capsule on urodynamics in bladder filling period of patients with post-menopause urethral syndrome of renal deficiency and blood stasis type.Methods A total of 36 patients with post-menopause urethral syndrome of renal deficiency and blood stasis type were randomly assigned to two groups:the trial group(24 patients were treated with Niaochangshu capsule) and the control group(12 patients were treated with Nilestriol).All patients were treated for 8 weeks.The changes of the urodynamic indexes in bladder filling period(the capacity of the bladder,the compliance of the bladder and the sensitivity of the bladder) were compared between the two groups.Results After treatment,the urodynamic index,including the maximum cystic capacity,the volume at the first desire to void and the cystic compliance were evidently improved in both of the trial group and the control group(P0.05).Conclusion Niaochangshu capsule is effective in treating the patients with post-menopause urethral syndrome of renal deficiency and blood stasis type.It can increase the cystic capacity and compliance,step down the sensitivity of the bladder.Its effect is similar to Nilestriol.

ObjectiveTo investigate the effect of Dendrobium officinale polysaccharides （DOP） in reversing carbon tetrachloride （CCl₄）-induced hepatic fibrosis （HF） in rats via the Notch signaling pathway and evaluate the therapeutic effect of DOP by ultrasound elastography. MethodFifty-six male SD rats were randomized into normal， model， colchicine （1×10^-4 g·kg^-1）， Fuzheng Huayu powder （0.45 g·kg^-1）， and low-， medium-， and high-dose （0.05， 0.1， 0.2 g·kg^-1） DOP groups （n=8）. The rats in the model group and each treatment group were injected subcutaneously with a mixture of CCl₄-olive oil （2∶3） once every 3 days for 10 weeks. After 6 weeks of modelling， the rats were administrated with corresponding drugs once a day for 4 weeks. Hematoxylin-eosin （HE） staining and Masson staining were employed to observe the pathomorphological changes of the liver tissue. An automatic biochemical analyzer was used to measure the serum levels of alanine aminotransferase （ALT）， aspartate transaminase （AST）， alkaline phosphatase （ALP）， and total bile acids （TBA）. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the serum levels of hyaluronic acid （HA）， laminin （LN）， type Ⅲ precollagen （PC-Ⅲ）， and type Ⅳ collagen （Col-Ⅳ）. The mRNA and protein levels of α-smooth muscle actin （α-SMA）， Notch1， Jagged1， and Hes1 in the liver tissue were determined by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot， respectively. The Young's modulus （YM） of the rat liver was measured by acoustic radiation force impulse （ARFI） elastography before and after treatment. Then， the correlations of YM with the serum levels of HA， LN， PC-Ⅲ， and Col-Ⅳ and the protein levels of α-SMA and Notch1 signaling pathway-related factors in the liver tissue were analyzed. ResultCompared with the normal group， the model group showed disordered arrangement of liver cell cords， obvious infiltration of inflammatory cells， appearance of a large number of fat vacuoles， and fibrous proliferation， elevated levels of ALT， AST， TBA， ALP， HA， LN， PC-Ⅲ， and Col-Ⅳ in the serum， and up-regulated mRNA and protein levels of α-SMA， Notch1， Jagged1， and Hes1 in the liver tissue （P<0.01）. Compared with the model group， drug interventions alleviated the pseudolobule formation and the collagen deposition in confluent areas. Except that the serum level of ALT in the low-dose DOP group had no significant changes， drug interventions， especially high-dose DOP， lowered the levels of ALT， AST， TBA， ALP， HA， LN， PC-Ⅲ， and Col-Ⅳ in the serum and down-regulated the mRNA and protein levels of α-SMA， Notch1， Jagged1， and Hes1 in the liver tissue （P<0.05， P<0.01）. The results of ARFI and correlation analysis showed that the YM of the liver tissue was increased in the model group （P<0.01） compared with that in the normal group， Compared with the model group， drug interventions decreased YM （P<0.01）. YM was positively correlated with the expression levels of HA， LN， PC-Ⅲ， α-SMA， Notch1， Jagged1， and Hes1s （r=0.754， 0.734， 0.801， 0.885， 0.896， 0.757， and 0.800， respectively， P<0.01）， and it had a moderate correlation with Col-Ⅳ （r=0.688， P<0.01）. ConclusionDOP can reverse HF by down-regulating the Notch1/Jagged1/Hes1 signaling pathway. YM can be used as an indicator in the assessment of the efficacy of DOP against HF.

ATP-binding cassette protein E (ABCE1) has been annotated as an Rnase L inhibitor in eukaryotes. Previous study showed that the overexpression of ABCE1 was related with the occurrence and clinical stage of lung adenocarcinoma. As an initial investigation into the novel functions of ABCE1, siRNA-expressing vectors targeting sites of the ABCE1 gene were constructed from RNAi-Ready pSIREN-DNR-DsRed-Express vector. Cultured 95-D and NCI-H446 lung carcinoma cells were transfected with the siRNA-expressing vectors using FuGENE 6 and transfection efficiency was determined by using fluorescence microscopy. The expression level of ABCE1 protein was determined by Western blot and immunofluorescence staining. Cell viability was determined by MTT, cell cycle was analysed by flow cytometry.The apoptotic rate was observed by ELISA. Fluorescence microscopy showed a satisfactory transfection efficiency which was about 42.70%. Cell viability and the growth fraction were markedly suppressed, whereas the apoptosis was significantly increased in SiRNA-95-D and SiRNA-NCI-H446 cells than controls(P< 0.05). It can be concluded that the siRNA targeting ABCE1 gene shows a dramatic inhibitory effect on RNA transcription and protein expression and a promoting effect on the apoptosis in 95-D/NCI-H446 cells, which offers a reliable base for the further in vivo experiment.

This study aims to investigate the role of slient mating-type information regulation 2 homolog 1(SIRT1)/tuberous sclerosis complex 2(TSC2)/mammalian target of rapamycin(mTOR) signaling pathways in the Periplaneta americana extract CⅡ-3-induced senescence of human leukemia K562 cells. K562 cells were cultured in vitro and treated with 0(control), 5, 10, 20, 40, 80, and 160 μg·mL~(-1) of P. americana extract CⅡ-3. Cell counting kit-8(CCK-8) and flow cytometry were employed to examine the proliferation and cell cycle of the K562 cells. Senescence-associated β-galactosidase stain kit(SA-β-gal) was used to detect the positive rate of senescent cells. Mitochondrial membrane potential was detected by flow cytometry. The relative mRNA level of telomerase reverse transcriptase(TERT) was determined by fluorescence quantitative PCR. The mRNA and protein levels of SIRT1, TSC2, and mTOR were determined by fluorescence quantitative PCR and Western blot, respectively. The results showed that CⅡ-3 significantly inhibited the proliferation of K562 cells and the treatment with 80 μg·mL~(-1) CⅡ-3 for 72 h had the highest inhibition rate. Therefore, 80 μg·mL~(-1) CⅡ-3 treatment for 72 h was selected as the standard for subsequent experiments. Compared with the control group, CⅡ-3 increased the proportion of cells arrested in G_0/G_1 phase, decreased the proportion of cells in S phase, increased the positive rate of SA-β-Gal staining, elevated the mitochondrial membrane potential and down-regulated the mRNA expression of TERT. Furthermore, the mRNA expression of SIRT1 and TSC2 was down-regulated, while the mRNA expression of mTOR was up-regulated. The protein expression of SIRT1 and p-TSC2 was down-regulated, while the protein expression of p-mTOR was up-regulated. The results indicated that P. americana extract CⅡ-3 induced the senescence of K562 cells via the SIRT1/mTOR signaling pathway.

Objective To investigate the mRNA and protein expression of E3 ubiquitin ligase Iduna in non-small-cell lung cancer tissue and para-neoplastic lung tissue,and the correlation of the Iduna expression with clinicopathological factors and prognosis.Methods The expression levels of the Iduna mRNA and protein in non-small-cell lung cancer tissue and para-neoplastic lung tissue were determined by reverse transcriptase-polymerase chain reaction (RT-PCR),Western-Blot and immunohistochemistry respectively,and the correlation of the Iduna expression with clinicopathological factors and prognosis was analyzed.Results RT-PCR and Western-Blot showed the expression levels of the Iduna mRNA and protein in non-small-cell lung cancer tissue (0.468 ± 0.086 and 2.554 ± 0.544) were significantly higher than those in para-neoplastic lung tissue (0.203 ± 0.070 and 1.570 ± 0.316),there were statistical differences (P ＜ 0.05).Immunohistochemistry results showed that Iduna was negative expression in the alveolar epithelium cells,negative or weak positive expression in normal bronchial and positive expression in different degrees in the non-small-cell lung cancer tissue.Iduna high expression rate was negative correlation with tumor differentiation (P =0.002),Iduna high expression rate was positive correlation with large tumor size (P =0.044),TNM staging (P=0.015) and lymph node metastasis (P=0.009).Iduna high expression of I stage non-small-cell lung cancer patients was correlated with poor post-operative survival (P =0.016).Conclusions High expression of Iduna may be related to the process of invasion and metastasis of nonsmall-cell lung cancer.It is possible that Iduna serve as potential markers for predicting prognosis in nonsmall-cell lung cancer.

OBJECTIVE: To investigate the effects of compound preparation of Cordyceps sinensis and Tripterygium hypoglaucum (CSTHC) on survival time of grafted pigskin after allogeneic transplantation and its mechanism. METHODS: The pigskin was treated with CSTHC solution before allogeneic transplantation, and CSTHC ointment was applied for external use on the grafted pigskin after skin transplantation. Cyclosporine A (CsA) and normal saline were served as control. The survival time, the appearance and the histomorphological changes of the grafted pigskin were observed. The histomorphological changes of testicles in pigs were also examined. The CD4 and CD8 expressions in the grafted pigskins were measured by immunohistochemical method. The white blood cell count in peripheral blood and the liver and renal functions were also examined. RESULTS: The survival time of the grafted pigskin in the CSTHC-treated group was (28.50+/-3.26)d, which was much longer as compared with (10.60+/-1.52)d in the untreated group (P<0.01). The survival time of the grafted pigskin in the CsA-treated group was (28.33+/-3.50)d, and there was no remarkable difference in the survival time of the grafted pigskin between the CsA-treated group and the CSTHC-treated group. The expressions of CD4 and CD8 were lower in the CSTHC-treated group than those in the untreated group on the 7th and 14th day after skin graft (P<0.05), while there was no significant difference in the indices between the CSTHC-treated group and the CsA-treated group. The WBC count was higher in the untreated group than that in the CSTHC-treated group or CsA-treated group on the 7th day after skin graft (P<0.05). CONCLUSION: CSTHC can prolong the survival time of allogeneic grafted pigskin. Its mechanism of inhibiting the immunological rejection may relate to decreasing the expressions of CD4(+) and CD8(+) in the grafted pigskin and reducing the local inflammatory reaction.

Objective To observe the influence of the short effect antihypertension drugs- nifedipine and medial effect antihypertension drugs- extended release nifedipine on the blood pressure variability (BPV) in essential hypertension(EH). Methods Twenty-five EH patients were underwent 24-hour noninvasive ambulatory blood pressure monitoring (ABPM) and observed their BPV respectively before taking drugs, after taking nifedipine and extended release nifedipine. Meantime,25 normotensive controls (NC) were observed. Results (1)BPV in EH group was higher than that in controlled group and the severer the rise of blood pressure, the more obvious the increase of BPV (P 0.05). Conclusions Nifedipine could increase BPV but extended release nifedipine did not change BPV while they decreased blood pressure. Effect of extended release nifedipine was better than nifedipine in decreasing blood pressure.
