Objective: To analyze the efficacy and safety of cytoreduction surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) for pseudomyxoma peritonei (PMP) in the early stage. Methods: The clinical data, including pathological features, recurrence and survival of 65 PMP patients in the early stage underwent CRS combined with HIPEC in Aerospace Center Hospital from January, 2011 to December, 2018 were retrospectively analyzed. Results: 65 patients with early stage PMP underwent CRS+ HIPEC. Among these patients, 25 were males and 40 were females, and the mean age was 52.5 years. The median peritoneal cancer index was 3 (0-16). The score of completeness of cytoreduction (CC) of 63 patients (96.9%) was 0, and 2 patients (3.1%) was 1. No perioperative death occurred, the incidence of surgical complications above grade 3 was 3.1%. Three patients relapsed during the follow-up period, including 1 patient with low-grade PMP, 1 patient with high-grade PMP, and 1 patient with high-grade PMP accompanied by signet ring cell. The 5-year disease-free survival rate of the whole group was 92.4%. Conclusions PMP patients in the early stage treated by CRS combined with HIPEC can achieve benefit and safety. A close long-term follow-up is necessary.

Objective To evaluate the outcome of ST-segment elevation myocardial infarction (STEMI) patients received different reperfusion therapies. Methods The 238 consecutive STEMI patients were enrolled from February 2012 to December 2012. According to the current guideline of PCI and the choice of patients, the patients were divided into the groups of percutaneous coronary intervention (PCI), ifbrinolysis, and conservative medication. The major adverse cardiac events (MACE) was analyzed in a follow up of 6 months. Results (1) The enrolled patients included the 210 patients received PCI (88.2%), 14 patients received fibrinolysis (5.9%) and 14 patients received conservative medication (5.9%).The Median time of D2B was 110minutes.(2) The rate of late stent thrombosis was signiifcant higher in BMS than DES (n=2, 2.8%vs 0, P < 0.05) . (3) The PCI group had a signiifcantly higher incidence of stroke than the ifbrinolysis group and the conservative medication group (1.0%vs 0, P < 0.05;1.0%vs 0, P<0.05). (4) The PCI group had a signiifcantly higher incidence of bleeding compared to the thrombolysis group and the medication group (1.0% vs 0, P < 0.05; 1.0% vs 0%, P < 0.05). Conclusions The majority of STEMI patients received PCI;The D2B time, which was required<90 minutes in guideline of PCI, was found delayed in our study;Compared to ifbrinolysis and conservative medication, PCI showed better clinical outcomes of STEMI patients.

Objective: To investigate the clinicopathological features and treatment strategy of pseudomyxoma peritonei (PMP) of ex-tra-appendiceal origin. Methods: Clinical data of 34 patients diagnosed with PMP of extra-appendiceal origin who were treated by cy-toreduction surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in the Aerospace Center Hospital from September 2011 to February 2019 were retrospectively analyzed. Clinical and imaging features were summarized and the Log-rank test was used for survival analysis. Results: The clinical manifestations of the 34 patients with PMP of extra-appendiceal origin were mainly abdomi-nal distension (58.8%) and abdominal pelvic mass (52.9%), which are very similar to those of appendiceal PMP. The incidence of main complications after CRS and HIPEC was 14.7%. During the follow-up period of a median of 12 months (range 1-46 months), 9 patients died, and the 1-and 3-year overall survival rates were 69.6% and 53.5%, respectively. In the univariate analysis, peritoneal cancer in-dex (PCI)>20, no HIPEC, and non-radical surgery were significant risk factors for poor prognosis, while gender, age, origin, and patho-logical type did not show significant correlations. Conclusions: The clinical features of PMP of extra-appendiceal origin are not differ-ent to those of PMP originating from the appendix. It is difficult to ascertain the primary lesion before the operation; however, regard-less of the origin, CRS combined with HIPEC is always a safe and effective treatment choice.

OBJECTIVETo detect the estrogenic activity of genistein and apigenin with ER-positive cell line MCF-7 human breast cancer cells.

METHODMTT method was adopted to study the impact of genistein and apigenin on MCF-7 proliferation in vitro. Real-time RT-PCR method was used to detect their impact on ERalpha, ERbeta, PR and PS2 mRNA expression levels.

RESULTGenistein and apigenin promoted the proliferation of MCF-7. Genistein 1 x 10(-10) mol x L(-1) group showed a significant increase in the expression of ERa mRNA levels or a 17. 76 times more than the control group and a 1.75 times more than the E2 group. Apigenin notably promoted the PR mRNA expression or a 4. 57 times more than the control group and a 1.11 times more than the E2 group. Both of them had different effect in promoting ERalpha, ERbeta, PR or PS2 mRNA.

CONCLUSIONBoth genistein and apigenin have a strong estrogen-like effect. Although they have different effect in promoting estrogenic response genes (such as ERa, ERbeta, PR and PS2 mRNA), genistein shows a stronger activity than apigenin. It also suggests that the signaling pathways of phytoestrogens showing estrogen-like effect are not completely identical with estrogen pathways. The B-cycle position of flavonoids is one of the key sites to estrogen-like activity, and isoflavones (cycle B on site 3) show stronger estrogen-like activity than flavones (B-cycle lies in site 2).

Objective:To investigate the changes of intestinal microecology in the early stage of sepsis rat model by 16S rDNA sequencing.Methods:Sixty male Sprague-Dawley (SD) rats were randomly divided into cecal ligation and puncture (CLP) group and sham operation group (Sham group), with 30 rats in each group. In the CLP group, sepsis rat model was reproduced by CLP method; the rats in the Sham group only underwent laparotomy without CLP. At 24 hours after the operation, the intestinal feces and serum samples of 8 rats in each group were collected. The survival rate of the rest rats was observed until the 7th day. The level of serum tumor necrosis factor-α (TNF-α) was detected by enzyme-linked immunosorbent assay (ELISA). Intestinal feces were sequenced by 16S rDNA sequencing technology. The operational taxonomic unit (OTU) data obtained after sequence comparison and clustering was used for α diversity and β diversity analysis, principal coordinate analysis and linear discriminant analysis effect size analysis (LEfSe) to observe the changes of intestinal microecology in early sepsis rats and excavate the marker flora.Results:At 24 hours after the reproduction of the model, the rats in the CLP group showed shortness of breath, scattered hair and other manifestations, and the level of serum TNF-α increased significantly as compared with that in the Sham group (ng/L: 43.95±9.05 vs. 11.08±3.27, P < 0.01). On the 7th day after modeling, the cumulative survival rate of the Sham group was 100%, while that of the CLP group was 31.82%. Diversity analysis showed that there was no significant difference in α diversity parameter between the Sham group and the CLP group (number of species: 520.00±52.15 vs. 492.25±86.61, Chao1 richness estimator: 707.25±65.69 vs. 668.93±96.50, Shannon index: 5.74±0.42 vs. 5.79±0.91, Simpson index: 0.93±0.03 vs. 0.94±0.05, all P > 0.05). However, the β diversity analysis showed that the difference between groups was greater than that within groups whether weighted according to OTU or not (abundance weighted matrix: R = 0.23, P = 0.04; abundance unweighted matrix: R = 0.32, P = 0.01). At the phylum level, the abundance of Proteobacteria and Candidatus_sacchari in the CLP group increased significantly as compared with the Sham group [18.100% (15.271%, 26.665%) vs. 6.974% (2.854%, 9.764%), 0.125% (0.027%, 0.159%)% vs. 0.018% (0.008%, 0.021%), both P < 0.05]. At the genus level, the abundance of opportunistic pathogen including Helicobacter, Ruthenium, Streptococcus, Clostridium ⅩⅧ in the CLP group was significantly higher than that in the Sham group [5.090% (1.812%, 6.598%) vs. 0.083% (0.034%, 0.198%), 0.244% (0.116%, 0.330%) vs. 0.016% (0.008%, 0.029%), 0.006% (0.003%, 0.010%) vs. 0.001% (0%, 0.003%), 0.094% (0.035%, 0.430%) vs. 0.007% (0.003%, 0.030%), all P < 0.05], and the abundance of probiotics such as Alloprevotella and Romboustia was significantly lower than that in the Sham group [7.345% (3.662%, 11.546%) vs. 22.504% (14.403%, 26.928%), 0.113% (0.047%, 0.196%) vs. 1.229% (0.809%, 2.29%), both P < 0.01]. LEfSe analysis showed that the probiotics belonging to Firmicutes were significantly enriched in the Sham group, and Romboustia was the most significantly enriched species. Opportunistic pathogens such as Helicobacter, Streptococcus and Clostridium ⅩⅧ were significantly enriched in the CLP group, Helicobacter_NGSU_ 2015 was the most significantly enriched species. Conclusion:In the early stage of sepsis, the intestinal microbiota structure of rats is significantly changed, which mainly shows that the abundance of Alloprevotella and other probiotics is significantly reduced, while that of Helicobacter and other opportunistic pathogens is significantly increased.
