Currently,lymph node metastases(LNM)are seen as the gateway to distant metastases in CRC and play a crucial role in the Tumor Node Metastasis(TNM)staging system[1,2].Tumor deposits(TD)have been identified as another histological feature with a strong prognostic impact but are currently only deemed clinically relevant in the absence of LNM[2,3].TD are clusters of tumor cells in the fat surrounding the bowel and are often associated with nerves,vessels and lymphatic tissue,giving the cancer cells access to multiple routes of spread[4].

Introduction: Obstetric emergencies are common throughout the world and more particularly in developing countries where they are responsible for high maternal-fetal mortality and morbidity. Objective: Study obstetric emergencies in the maternity ward of Kara University Hospital. Method: Retrospective and descriptive study from April 1, 2022 to March 30, 2023, carried out in the Obstetrics and Gynecology Department of Kara University Hospital. Results: Eight hundred and thirty-five (835) obstetric emergencies were recorded out of 2215 admissions, i.e. a frequency of 37.7%. The average age of the patients was 26.7 with a range of 14 and 45 years. They were primigravidas (36.7%) and nulliparous (38.7%), referred (84.7%) and came from rural areas (72%). Emergencies occurred in the 3rd trimester in 74.1% and in parturients (54.1%). Preeclampsia (27%), cessation of progression of labor due to feto-pelvic disproportion (12.4%), postpartum hemorrhage (7.5%) constituted the main obstetric emergencies. In 44.8%, the delivery was carried out vaginally. Magnesium sulfate was the most used drug, i.e. 30.1%;followed by antihypertensive medications in 28.1%. Blood transfusion was performed in 24.3%. The evolution was simple in 90.9%. The maternal fatality rate was 1.6%. The perinatal case fatality rate was 12.3%. Conclusion: Obstetric emergencies are common, dominated by preeclampsia, stopping progress of labor and postpartum hemorrhages. They are responsible for high morbidity and mortality.

Cancer Biology & Medicine 2015年第3期12卷 193-200页

There has been a paradigm shift in medicine away from tradition, anecdote and theoretical reasoning from the basic sciences towards evidence-based medicine(EBM). In palliative care however, statistically significant benefits may be marginal and may not be related to clinical meaningfulness. The typical treatment vs. placebo comparison necessitated by ‘gold standard' randomised controlled trials(RCTs) is not necessarily applicable. The complex multimorbidity of end of life care involves considerations of the patient's physical, psychological, social and spiritual needs. In addition, the field of palliative care covers a heterogeneous group of chronic and incurable diseases no longer limited to cancer. Adequate sample sizes can be difficult to achieve, reducing the power of studies and high attrition rates can result in inadequate follow up periods. This review uses examples of the management of cancer-related fatigue and death rattle(noisy breathing) to demonstrate the current state of EBM in palliative care. The future of EBM in palliative care needs to be as diverse as the patients who ultimately derive benefit. Non-RCT methodologies of equivalent quality, validity and size conducted by collaborative research networks using a ‘mixed methods approach' are likely to pose the correct clinical questions and derive evidencebased yet clinically relevant outcomes.

Cancer causes millions of deaths annually and microtubule-targeting agents （MTAs） are the most commonly-used anti-cancer drugs. However, the high toxicity of MTAs on normal cells raises great concern. Due to the non-selectivity of MTA targets, we analyzed the interaction net- work in a non-cancerous human cell. Subnetworks of fourteen MTAs were reconstructed and the merged network was compared against a randomized network to evaluate the functional rich- ness. We found that 71.4% of the MTA interactome nodes are shared, which affects cellular pro- cesses such as apoptosis, cell differentiation, cell cycle control, stress response, and regulation of energy metabolism. Additionally, possible secondary targets were identified as client proteins of interphase microtubules. MTAs affect apoptosis signaling pathways by interacting with client pro- teins of interphase microtubules, suggesting that their primary targets are non-tumor cells. The paclitaxel and doxorubicin networks share essential topological axes, suggesting synergistic effects. This may explain the exacerbated toxicity observed when paclitaxel and doxorubicin are used in combination for cancer treatment.

The article examines the role of the seas in Sumerian and Akkadian royal inscriptions and literary texts from the third millennium BC *** tracing the presence of the sea in these texts,it becomes clear that the Upper and Lower Sea—or the Mediterranean and the Persian Gulf,though the former could shift geographically—could stand as temiinal points for imperial control;as an obstacle or opponent to tackle;and moreover,as markers of distant,even constructed ***,the sea functioned as both a real and imagined border within the Mesopotamian worldview.

Purpose: The primary aim of this paper is to design, create, and improve functional and artificial Bruch’s membranes (BM) using bioengineering techniques, which can be applied in the treatment of maculopathies by supporting the growth and maintenance of retinal pigment epithelium (RPE) cells, thereby potentially enabling subretinal implantation in patients. Methods: We fabricated by electrospinning ultrathin 3D nanofibrous membranes from Polycaprolactone (PCL), and different concentrations of gelatin (5%, 15% and 30%). ARPE-19 cells were seeded onto these artificial membranes. MTT assays were performed in order to evaluate ARPE-19 cell viability and cytotoxicity. IF assays were realized to observe the ARPE-19 cells onto each membrane. Ultrastructure of the modified Bruch’s membrane and ARPE-19 morphology after 25 days of culture were studied with transmission and scanning electron microscopy. To evaluate expression changes in markers of ARPE-19 (RPE65 and ZO-1) qRT-PCR assays were realized. Data from three independent experiments were pooled and expressed as the mean SD. A confidence level of P 0.05 was considered to be statistically significant. Results ARPE-19 cells grew on PCL/Gelatin membranes mainly in PCL/30% gelatin combination, which had not cytotoxic effect. RPE65/cytokeratin-18/ and actin-positive ARPE-19 cells formed a correctly orientated monolayer of polygonal cells with morphological polarity. The apical cell surfaces exhibited abundant protruding microfolds. Moreover, zones of polygonal border look as if ARPE-19 cells fused among, suggesting the presence of tight junctions. The expression of RPE65 and ZO-1 was unchanged. Conclusions: PCL/30% Gelatine membranes may imitate the natural BM to such extent that they support RPE-cells and exhibited RPE-like morphology. The engineering of a human RPE monolayer with these artificial BM, emulating the in vivo retina, arouse their potential subretinal implantation in patients with wet age-related macular degene
