The molecular mechanism of GSDMB regulating the fate of intestinal epithelial cells / 西安交通大学学报(医学版)

【Objective】 To explore the molecular mechanism of Gasdermin B (GSDMB) regulating the fate of intestinal epithelial cells. 【Methods】 The human GSDMB plasmid was overexpressed into two human intestinal epithelial cell lines (NCM460 and HT-29 cells) and human colon-derived organoids. Western blotting was used to confirm the efficiency of electroporation. Cell counting kit (CCK8), cell apoptosis, and cell cycle by flow cytometry were performed to analyze the effect of GSDMB overexpression on cell function. Transcriptome sequencing was used to analyze the downstream effector molecules of GSDMB. T test was used to compare the data between the two groups. 【Results】 The overexpression of GSDMB protein in the two intestinal epithelial cell lines was successfully reconstructed. The absorbance value (A) of human intestinal epithelial cells overexpressing GSDMB protein [NCM460 cells: (1.17±0.01), HT-29 cells: (0.96±0.06)] was significantly lower than that of blank control cells [NCM460 cells: (1.67±0.12), HT-29 cells: (1.24±0.07)] (t=7.24 and 5.46, P<0.05). The number of apoptotic cells in the GSDMB overexpression group [NCM460 cells: (12.03±1.55), HT-29 cells: (29.30±4.48)] was significantly higher than that in the blank group [NCM460 cells: (4.96±1.74), HT-29 cells: (6.95±3.42)] (t=5.26 and 6.97, P<0.05). Cell cycle analysis showed that the ratio of cells at G0/G1 phase in the GSDMB overexpression group [NCM460 cells: (47.98±5.28)%, HT-29 cells: (38.04±3.45)%] was significantly lower than that in the control group [NCM460 cells: (59.54±3.90) %, HT-29 cells: (63.81±1.76) %] (t=3.05 and 11.53, P<0.05). Transcriptome sequencing results showed that the dual specificity phosphatase 4 and 6 (DUSP4 and DUSP6) genes were significantly upregulated after GSDMB protein expression. Fluorescence quantitative PCR results confirmed that the relative expression levels of DUSP4 (2.45±0.15) and DUSP6 (4.34±0.22) in intestinal epithelial cells transfected with GSDMB were significantly higher than those in the control group (1.06±0.05 and 1.01±0.02) (t=15.08 and 26.52, P<0.05). After GSDMB-expressing NCM460 cells were treated with the DUSP inhibitor BCI, the BCI treatment group had a significantly increased expression level of p-ERK compared to the control group [(1.14±0.17) vs. (0.58±0.12)] (t=5.42, P=0.002); the A value (1.84±0.07) and G0/G1 phase ratio (59.83±2.17)% in the BCI treatment group were significantly higher than those in the non-treatment group [(1.52±0.10) and (52.10±2.23)%] , and the number of apoptosis in the BCI treated group (7.60±0.56) was significantly lower than that in the untreated group (12.57±1.00) (t=4.71, 4.31, 7.52, P<0.05). TUNEL staining in human colon organoids showed a significant increase in apoptotic cells, and the relative expression level of DUSP6 protein (0.85±0.09) was significantly higher than that of the control group (0.21±0.04), accompanied by a decrease in p-ERK levels [(0.83±0.18) vs. (0.19±0.06)] , with statistical significance (t=11.95, P<0.001; t=6.56, P<0.001). 【Conclusion】 GSDMB may inhibit cell proliferation, induce cell cycle arrest, and promote apoptosis by upregulating dual specificity phosphatase DUSP6-mediated ERK phosphorylation, thus affecting the fate of intestinal epithelial cells.

Objective:To observe effect of Jingulian capsule on the proliferation of human breast cancer MDA-MB-231 cells and investigate its action mechanism against triple negative breast cancer （TNBC）. Method:The ingredients of Jingulian capsule were identified by ultra-performance liquid chromatography-tandem mass spectrometry（UPLC-MS/MS）. The inhibitory effect of Jingulian capsule at different doses （0.125，0.25，0.5，1，and 2 g·L^-1） against the proliferation of MDA-MB-231 cells were detected by methyl thiazolyl tetrazolium （MTT） assay. After treatment for 24 h， the morphological changes in nuclear apoptosis of MDA-MB-231 cells were detected by Hoechst 33258 staining. The effect of different concentrations of Jingulian capsule on the apoptosis and cycle of MDA-MB-231 cells after different treatment time were determined by flow cytometry. The protein expression levels of Poly-ADP-ribose polymeras （PARP）， proto-oncogene c-Myc， cyclin B₁， and phosphorylated extracellular signal-regulated kinase （p-ERK） in each group were assayed by Western blot. Result:A total of 113 compounds in Jingulian capsule were identified by UPLC-MS/MS. As revealed by MTT assay，compared with blank group，Jingulian capsule （0.125，0.25，0.5，1，2 g·L^-1） significantly inhibited viability of MDA-MB-231 cells （<italic>P</italic><0.01）， with the half maximal inhibitory concentration （ IC₅₀） of（0.13±0.02）g·L^-1. According to flow cytometry，compared with the blank group，Jingulian capsule at 1 g·L^-1 significantly induced the apoptosis of MDA-MB-231 cells （<italic>P</italic><0.05）and Jingulian capsule at 0.5， 1 g·L^-1 obviously increased the number of MDA-MB-231 cells in S phase （<italic>P</italic><0.05，<italic>P</italic><0.01）. The results of Western blotting demonstrated that the protein expression levels of PARP，c-Myc，and cyclin B₁ in 0.5， 1 g·L^-1Jingulian capsule groups were remarkably down-regulated as compared with those in the blank group（<italic>P</italic><0.01）， and the protein expression level of p-ERK in 1 g·L^-1Jingulian capsule group was also down-regulated （<italic>P</italic><0.01）. Conclusion:Jingulian capsule is able to inhibit the proliferation of MDA-MB-231 cells，induce S phase cell cycle arrest， and promote their apoptosis， which may be related to the inactivation of the MAPK signaling pathway.

MicroRNA abnormality is closely related to the development of acute leukemia. This study was aimed to investigate the differential expression of miR-143 in bone marrow cells between patients with acute leukemia and normal people. Bone marrow cells from 50 AL patients and 20 normal people were collected respectively and the total RNA was isolated routinely. The quantitative real-time PCR (Q-PCR) method was used to detect the expression levels of miR-143 in these specimens. The results showed that compared with the normal people, the expression of miR-143 in AL patients was significantly decreased (p < 0.05), which significantly increased after complete remission; besides, the expression of miR-143 was negatively correlated with the expression of DNMT3A mRNA, a known target gene of miR-143. It is concluded that the expression of miR-143 in bone marrow cells of AL patients is down-regulated which may be related with the development of acute leukemia.

Importance of early diagnosis and operative treatment for trans-scaphoid perilunate dislocation / 中国骨伤

<p><b>OBJECTIVE</b>To evaluate the effectiveness of open reduction and internal fixation and repair of palmar ligment in treating trans-scaphoid perilunate dislocation.</p><p><b>METHODS</b>From June 1995 to June 2001,14 patients with trans-scaphoid perilunate dislocation were treated with open reduction and internal fixation and repair of palmar ligment. Among them,there were 13 males and 1 female,the ranging in age from 21 to 38 years,averaged 25.4 years. All patients were posterior dislocation and all operations were performed within 2 weeks after injury.</p><p><b>RESULTS</b>All patients were followed up from 24 to 60 months with an average of 28.3 months. Thirteen scaphoid fractures were primary healed and functions of wrist joint were good. Bone disunion was found in 1 case and part functions of wrist joint were limited. No found necrosis of lunate and scaphoid. According to clinical scoring system of Cooney, 9 case got excellent results, 3 good, 1 fair and 1 poor.</p><p><b>CONCLUSION</b>Open reduction and internal fixation and repair of palmar ligament is effective in treating trans-scaphoid perilunate dislocation,which can early provide steady fixation for scaphoid,and profit to recover blood supply of lunatum and subterminal scaphoid.</p>

Application of circular staplers in cervical esophagogastric anastomosis after esophageal cancer resection / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To evaluate safety and feasibility of circular staplers in cervical esophagogastrostomy after esophageal cancer resection.</p><p><b>METHODS</b>The clinical data of patients with esophageal carcinoma were analyzed retrospectively. These patients underwent esophagectomy and cervical esophagogastrostomy with mechanical staplers from August 2009 to April 2011 in the Henan Provincial People's Hospital.</p><p><b>RESULTS</b>A total of 202 patients had the anastomosis performed successfully except for one case who had esophageal tear during anastomosis and required hand-sewn repair. There was no operative mortality. Six patients developed cervical anastomotic leakage after operation, and all were treated conservatively. There was no thoracic anastomotic leakage and other complications related to anastomosis. Two patients had obvious gastroesophageal reflux. After a median of 10.2 months of follow-up, there was no anastomotic stricture.</p><p><b>CONCLUSION</b>Circular mechanical stapling in cervical esophagogastric anastomosis is a safe and feasible operative procedure.</p>
