Aim To evaluate the effect of ZST93 on the proliferation in human chronic myeloid leukemia(CML)cells(K562)and explore the possible mechanism.Methods MTT assay, cell growth curve and inverted microscope were used to investigate the effect of ZST93 on proliferation of K562 cells.Cell transfection and Western blot were performed to detect the autophagy, while PI staining, Annexin V-FITC/PI and flow cytometry were conducted to determine cell apoptosis and its anticancer mechanism.Results ZST93 could significantly inhibit the proliferation of K562(IC50=2.59 μmol·L-1)and induce cell cycle arrest at G1-phase in a dose- and time-dependent manner.Also, through leading to accumulation of GFP-LC3, transition into LC3- II from LC3- 1 , and decrease of p62 expression, ZST93 induced autophagy initiation and autophagic flux.Furthermore, ZST93 induced extrinsic apoptotic pathway by activating caspase-8, and further promoted the cleavage of apoptosis related proteins including caspase-9, caspase-3 and PAR P.Moreover, Z-DEYD-FMK, the specific inhibitor of caspase-3 , could dramatically reduce the apoptosis induced by ZST93.Taken together, ZST93 could effec tively inhibit CML cells, arrest eell cycle at G,-phase, induce cell apoptosis anrl initiate autophagy.Conclusions The potential mechanism may he related to the regulation of autophagy intiation/caspase-8/caspase-3 signaling pathway, which provides a new idea and theoretical basis for the treatment of CML.

Actin-like 6A (ACTL6A), also known as BAF53A, is an SWI / SNF subunit of chromatin-remodeling factors and plays an important role in regulating stem cell function. Recent studies found that ACTL6A was involved in tumor occurrence and development. However, the mechanism of ACTL6A in cisplatin resistance is still unclear. This study investigated the biological function and molecular mechanism of ACTL6A in maintaining cancer stem cell function and cisplatin resistance. First, analysis from TCGA, GEO, and GEPIA databases showed that ACTL6A expression levels in lung adenocarcinoma (LUAD) tissues and cisplatin resistant cells were dramatically higher than that in adjacent normal tissues and cisplatin sensitive cells (P < 0. 05), and ACTL6A high expression was positively associated with a poor prognosis of LUAD. Knockdown of ACTL6A enhanced cisplatin sensitivity (P < 0. 05), reduced tumor sphere (P<0. 05), inhibited cell migration (P<0. 05), and promoted cell apoptosis (P<0. 05) in A549 cells. Western blotting showed that knockdown of ACTL6A increased the protein expression of E-cadherin, and decreased the protein expression of N-cadherin, vimentin, and twist. Moreover, knockdown of ACTL6A inhibited the expression of cancer stem cell markers, including ALDH3A1, ALDH4A1, SOX2, OCT4, and Nanog. Subsequently, Hippo / YAP signaling-related proteins were analyzed by Western blotting. The results showed the expression of beta-TRCP and YAP was decreased in A549 cell with knockdown of ACTL6A. However, phosphorylation levels at S127 and S397 of YAP were increased and inhibited translocation of YAP into the nucleus for regulating related gene expression. In summary, ACTL6A maintained the stemness of lung cancer stem cells and promoted cisplatin resistance in A549 cells by inhibiting activation of the Hippo signaling pathway.

This paper summarized the effects of ecological planting on secondary metabolism firstly and pointed out that ecological planting can increase the content of secondary metabolites in plants, especially the content of defensive secondary metabolites. The possible mechanism was analyzed subsequently. Then, we reviewed the induction and utilization of secondary metabolism in the ecological planting of Chinese materia medica from the perspectives of biological control of pests and diseases, promotion of beneficial microorganism accumulation, optimization of mixed planting, regulation of no-tillage and straw cover. In this article, we pointed out that paying close attention to secondary metabolism is the most important feature of ecological planting of Chinese materia medica. Ecological planting can promote the accumulation of secondary metabolites of Chinese materia medica which means can improve the quality of Chinese materia medica, beneficial to the prevention and control of diseases, insects and weeds. Furthermore, lacking of systemic researches,the extensive verifications and systematic in-depth researches on the ecological planting of Chinese materia medica should be carry out urgently.

OBJECTIVETo investigate the feasibility and reliability on the quantitative evaluation of Colles' fracture by multislice CT (MSCT) multiplanner reconstruction (MPR).

METHODSA total of 36 patients with Colles' fracture from July 2011 to July 2014 were investigated in this study. There were 11 males and 25 females with a mean age of (42.5 ± 5.4) years old (ranged 35 to 72 years). All the patients underwent anteroposterior and lateral X-ray films and MSCT scans on wrist joints within 2 days after trauma. Images were sent to the workstation through picture archiving and conserving system (PACS). One associate chief physician independently and respectively measured the dorsal intercalation depth of distal fracture block, palmar angle and dislocation degree of wrist articular surface collapse on anteroposterior and lateral X-ray film and MSCT-MPR. The time interval between the two measurements was 2 weeks. All the data between the first and second measurement on X-ray and MPR and the mean value between the X-ray and MPR was examined with paired t-test. The pearson analyzed their correlation.

RESULTSAmong the 35 cases, 35 cases of palmar angle, 21 cases of intercalation depth and 16 cases of dislocation of wrist articular surface collapse could be measured on both X-ray and MPR. For the above parameters, the first measurement results were (12.5 ± 3.6)°, (4.5 ± 2.1) mm, (3.7 ± 1.6) mm and the second measurement results were (4.8 ± 2.2)°, (6.4 ± 3.6) mm, (2.5 ± 1.2) mm on X-ray films respectively. The first measurement results on MPR were (14.5 ± 5.3)°, (4.2 ± 1.2) mm, (5.7 ± 2.3) mm, and the results were (13.2 ± 2.6)°, (4.7 ± 2.2) mm, (4.6 ± 2.1) mm for the second measurement respectively. The three parameters between the first and second measurement on plain film had statistical difference and low correlation (r = 0.681, 0.640, 0.345, P < 0.05). The data between the first and second measurement on MPR showed that the dislocation degree of wrist articular surface collapse had statistical difference (P < 0.05) and no statistical significance was found for the other two parameters (P > 0.05), with the moderate correlation (r = 0.954, 0.854, 0.642). The three parameters had low or moderate correlation with each other on X-ray (r = 0.454, 0.532, 0.378, P < 0.05), compared with the mean value on MPR.

CONCLUSIONUsing MSCT MPR images may carry on the multiple parameter measurement of Colles fracture, to make quantitative evaluation, and repeated measurement is better reliability.

OBJECTIVETo explore the effect of hepatitis B virus (HBV) X protein (HBX) on expression of the host gene Wnt induced secreted protein-1 (WISP-1) that is related to the pathogenic process of hepatocellular carcinoma (HCC).

METHODSTumor and paratumor tissues were collected from HCC patients, and normal liver tissues were collected from healthy controls. Immunohistochemistry was used to evaluate the in vivo presence and expression levels of HBX and WISP-1 in the three tissue types. HepG2 cells stably transfected with pc-DNA3.1(+)-HBX or with pc-DNA3.1(+) only (G0, control) were generated and used to examine in vitro the HBX-induced changes in WISP-1 expression at the mRNA and protein levels by reverse transcription polymerase chain reaction and western blotting, respectively.

RESULTSThe HCC tissues showed significantly higher rates of positivity for WISP-1 expression than the non-tumor controls (76.6% vs. paratumor: 23.4% or normal tissues: 0%, x2= 35.967, P less than 0.01). HBX increased WISP-1 expression in HepG2 cells at both the mRNA (1170.33 +/- 41.26 vs. G0: 265.34 +/- 27.47, t = 31.63, P less than 0.01) and protein (240.33 +/- 11.37 vs. G0: 40.33 +/- 7.09, F = 600.57, P less than 0.01) levels.

CONCLUSIONHBV may up-regulate expression of the host gene WISP-1 through its X protein and thus promote the development of HCC.
