OBJECTIVE To evaluate the anti-tumor activities of WX-127-07,a new microtubule-tar-geting agent invitroand probe its molecular mechanism. METHODS The well-known microtubule-targe-ting anti-tumor drugs taxol,vincristine and anti-gout drug colchicine were used as positive controls. The anti-proliferation activity was examined in five different cell lines after treatment with WX-127-07(0.3 -300 nmol·L-1 )for 72 h by SRB assay. The cell cycle arrest profile was assayed by flow cytometry. The multiparameters of cytotoxicity,cell morphology,apoptosis and different signaling pathways related to tumorigenesis and inflammation were analyzed using the high content analysis platform. Tubulin tryptic digestion and competition inhibition assay for colchicine or vinblastine site were used to confirm the bind-ing site in microtubules at a molecular level. RESULTS All the tested compounds obviously inhibited the growth of A549,HepG2,HeLa,HLF and HUVEC cells. The lC50 values of WX-127-07 were 4.47±0.05, 5.18±0.08,4.90±0.19,4.10±0.16 and(5.04±0.08)nmol·L-1 respectively,lower than those of colchicine〔the lC50 values were 21. 17 ± 1. 22,14. 19 ± 0. 53,43. 80 ± 1. 64,145. 89 ± 10. 97 and( 27. 67 ± 1.79)nmol·L-1 ,respectively〕and those of vincristine〔the lC50 values were 16.51±0.36,16.76±0.33, 27.80±2.75,43.80±1.48 and(9.15±0.78)nmol·L-1 ,respectively〕,but were similar to or lower than those of taxol〔the lC50 values were 10. 68 ± 0. 61,12. 86 ± 0. 25,4. 81 ± 0. 61,102. 07 ± 15. 17 and( 3. 04 ± 0.12)nmol·L-1 ,respectively〕. High content multi-parameter analysis revealed that WX-127-07 induced a concentration-dependent microtubular depolymerization(P=0.0075)with the same pattern as colchicine and vincristine,but at a lower concentration. Both WX-127-07 and positive drugs could induce cell cycle arrest in A549 cells,increase nuclear membrane permeability and early signs of apoptosis in HepG2 cells,but neither cancer related pathways nor inflammation related pathways were affected. Microtubular competition inhibition assay showed that WX-127-07 inhibited the binding of colchicine with tubulin(P =0.0259). Tryptic digestion of tubulin-WX-127-07 premixture showed a similar electrophoretic band to that of tubulin-colchicine premixture. CONCLUSION WX-127-07 is a novel microtubule-depolymerizing agent with anti-proliferation activity and acting on the colchicine binding site.

Objective To investigate the effects of different early enteral nutrient (EN) emulsions of TPF-T and TP on nutritional status and intestinal mucosal barrier in patients with septic shock. Methods From May 2017 to May 2018, 112 patients with septic shock were continuously enrolled in the Department of Intensive Care Unit of the First People's Hospital of Taizhou, and they were randomly divided into a TPF-T group and TP group, each group with 56 cases. After admission, the patients in both groups were all treated according to the 2016 Saving Sepsis Campaign (SSC) Guidelines for septic shock. Both groups were supported with EN, TPT-T group was given TPF-T EN emulsion rich in fish oil, while TP group was supported with standard TP EN emulsion, and the therapeutic course was consecutive 7 days in both groups. The differences in nutritional status, inflammatory response, immune function, intestinal mucosal barrier, gastrointestinal symptoms and prognosis were compared between the two groups. Results After EN, the nutrition indicators such as albumin (Alb), prealbumin (PA), transferrin (TRF) and immune indexes (IgA, IgG), human leukocyte DR antigens (HLA-DR) and D-lactic acid were increased in both groups, reaching the peaks on the 7th day after EN application, Alb, PA, TRF, IgA, IgG, HLA-DR in the TPF-T group were significantly higher than those in the TP group [Alb (g/L): 34.43±5.81 vs. 33.59±5.34, PA (mg/L): 269.83±47.56 vs. 252.67±41.92, TRF (g/L): 3.43±0.64 vs. 3.32±0.81, IgA (mg/L): 159.45±34.56 vs. 143.31±33.81, IgG (mg/L): 4 947.68±871.66 vs. 4 583.75±841.54, HLA-DR: (68.22±9.11)% vs. (62.21±9.69)%], and after EN, the D-lactic acid in the TPF-T group was significantly lower than that in the TP group (mg/L: 30.42±6.79 vs. 33.34±7.31). The inflammatory indicators of tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), procalcitonin (PCT), endotoxin and diamine oxidase (DAO) were all gradually reduced in two groups, reached the lowest levels on the 7th day after EN application, and all the above-mentioned indicators in the TPF-T group were significantly lower than those in the TP group [TNF-α (ng/L):95.43±20.69 vs. 109.59±23.45, CRP (mg/L): 21.33±16.35 vs. 32.36±17.83, PCT (μg/L): 1.24±1.21 vs. 4.18±1.32, endotoxin (U/L): 10.32±2.31 vs. 11.54±2.69, DAO (g/L): 19.45±8.49 vs. 25.47±9.41]. The incidences of gastric retention, diarrhea and paralysis of lower digestive tract in TPF-T group were significantly lower than those in TP group [gastric retention: 14.29% (8/56) vs. 32.14% (18/56), diarrhea: 12.50% (7/56) vs. 35.71% (20/56), paralysis of lower digestive tract: 7.14% (4/56) vs. 23.21% (13/56)], the length of hospital stay was significantly shorter in the TPF-T group than that in the TP group (days: 18.77±5.08 vs. 21.71±6.67, P < 0.05); however, there was no significant difference in mortality between the two groups [14.29% (8/56) vs. 21.43% (12/56), P > 0.05]. Conclusion TPF-T could more effectively maintain nutritional status, reduce inflammatory reaction, improve immunity, protect intestinal mucosal barrier function, and has fewer adverse reactions, which was helpful to improve the prognosis of septic shock patients.

Objective To illustrate the semiological characteristics of the three sub-types within the broad bilateral asymmetric tonic seizures (BATS),summarize their predictive values on lateralization and localization of seizure onset zone (SOZ),and analyze the difference between BATS and asymmetrical tonic limb posturing (ATLP).Methods A retrospective review of 385 patients who underwent stereotactic electrode implantation in the Sanbo Brain Hospital,Capital Medical University from September 2011 to May 2018 was performed.As long as there was a clinical epileptic seizure in the presence of BATS or ATLP,the patients were classified into the corresponding groups.Postoperative prognosis was assessed using Engel's grading criteria for a follow-up of no less than six months.Seizure descriptions were based on the classification of epileptic seizures introduced by Lüiders,which used arrows to connect the symptoms in chronological order.Results There was no statistically significant difference between the classic BATS and bilateral proximal tonic seizure in terms of whether it could be an independent seizure,as the onset and end of the seizure,with version and generalized tonic-clonic seizure (P>0.05).Compared with the ATLP,except for whether it could be an independent seizure (P=1.000) and onset before versive seizure (P=0.068),the BATS showed significantly different semiological features (P<0.05).The classic BATS and secondary motor area epilepsy had a 100.0% predictive accuracy on the lateralization of SOZ.In the patients with broad BATS,the SOZ distribution was more extensive,but it was rare in the orbitofrontal gyrus,frontal pole and mesial temporal lobe.Compared with the bilateral proximal tonic seizures from the other regions,those originated from supplementary somatosensory motor area and its adjacent areas were rare and showed no statistically significant difference (0/8 vs 40.0% (18/45),x2=3.226,P=0.072) but a low trend.The predictive value of BATS on lateralization of SOZ was higher than that of ATLP (84.9% (45/53) vs 57.1% (24/42),x2=9.086,P=0.003),and BATS was less originated from temporal lobe than ATLP (3.8% (2/53) vs 23.8% (10/42),x2=8.523,P=0.004).Conclusion Different from ATLP,the broad BATS are characterized by tonic proximal upper limb posturing,and have a higher predictive value on lateralization and localization of SOZ.
