Krukenberg tumor, a rare metastatic ovarian tumor arising from gastrointestinal adenocarcinoma mainly, tends to occur in premenopausal females. Finding the origin of a Krukenberg tumor is crucial for determining prognosis. In Eastern countries, the most common origin of Krukenberg tumor is stomach cancer, which is generally diagnosed via endoscopic biopsy to investigate an abnormal mucosal lesion. Here, we describe a case of huge adnexal mass in a 33-year-old woman who presented with abdominal distension. Two independent endoscopic examinations performed by experts in two tertiary university hospitals revealed no abnormal mucosal lesion. The patient was diagnosed with a Krukenberg tumor according to findings from random endoscopic biopsies taken from normal-looking gastric mucosa in our hospital. It is very rare to be diagnosed via a random biopsy in cases where three well-trained endoscopists had not found any mucosal lesion previously. Thus, in this case, random biopsy was helpful in finding the origin of a Krukenberg tumor.

Background Although platinum-based chemotherapy is a standard first-line treatment in advanced non-small cell lung cancer （NSCLC）, further research for the safety and efficacy of combination chemotherapy in elderly patients has been required. The purpose of this study was to evaluate the efficacy and safety of gemcitabine and carboplatin as first-line treatment in elderly patients with advanced NSCLC and to evaluate the prognostic factors. Methods Eligibility included：（1） age of 70 years or more, （2） histologically confirmed NSCLC, （3） chemotherapy-na＇l＇ve, （4） advanced disease with stage IIIB or IV, （5） Eastern Cooperative Oncology Group （ECOG） performance status （PS） 0-2, （6） adequate organ function. Patients received intravenous carboplatin （area under curve （AUC）=5） on day 1 and gemcitabine （1000 mg/m2） on days 1 and 8, every 3 weeks. Results The medical records of forty patients were reviewed retrospectively. Median age was 73.9 years （range, 70- 84.6）, and there were 27 men （67.5%）. Thirty-seven patients （92.5%） had ECOG PS 0-1. Adenocarcinoma was found in 57.5%. Median cycles were administrated with 4.5 per person （range： 1-6）. Best responses were partial response in 22 （55.0%） patients and stable disease （SD）in 13 （32.5%）. The median progression free survival （PFS） and overall survival （OS） were 5.9 months （95% CI： 4.5-7.3 months） and 9.6 months （95% CI： 8.2-11.0 months）, respectively. Grade 4 hematologic toxicities for neutropenia （7.5%）, thrombocytopenia （7.5%） and anemia （5.0%） were observed. Histology was significant prognostic factor for PFS （P=0.024）. Conclusion Gemcitabine and carboplatin combination chemotherapy is an effective and manageable treatment option in elderly advanced NSCLC patients with good performance status.

The Kulun region is located in the eastern Bainaimiao arc belt on the southeastern margin of the Central Asian Orogenic Belt(CAOB), adjacent to the North China Craton(NCC) to the south. This region records the closure of the PaleoAsian Ocean during the Paleozoic to early Mesozoic and is key to study the tectonic evolution of the northern margin of the *** conducted zircon U-Pb geochronology and Hf isotope analysis of volcanic-sedimentary and intrusive rocks in the Kulun region. The volcanic-sedimentary rocks were previously assigned an early Carboniferous age, but include volcanic rocks with ages of 267–266 Ma and sedimentary rocks with youngest detrital zircon age peaks of 265–244 Ma, which were intruded by a granite with an age of 242 Ma. This indicates that these rocks are actually middle Permian to Middle Triassic in age(267–242Ma) and correspond to the Qingfengshan and Liujiagou formations. Moreover, two volcanic rock samples have high εHf(t) values(+1.6 to +16.1) and relatively young two-stage Hf model ages(1095–327 Ma), indicating their sources associated with the CAOB. The age spectra and Hf isotopic characteristics of detrital zircons from the sedimentary rocks suggest that, during the middle Permian to Middle Triassic, the sedimentary provenance in the Kulun region was mainly the CAOB. However, by the Early Jurassic, the provenance changed to the NCC(i.e., the Inner Mongolia Paleo-uplift, IMPU). This result, combined with the development of a series of conglomerates on the northern margin of the NCC in the Late Triassic(i.e., Xingshikou, Xiaoyingzi,and Xiaohekou formations), indicates the Kulun region experienced an abrupt change in paleogeography during the Late Triassic, with the IMPU undergoing significant uplift and thus becoming the main sediment source in the Kulun region. Based on the Late Triassic alkaline igneous belt(235–215 Ma) in the IMPU, we speculate that this uplift was caused by detachment of the southward-subducting Paleo-Asian oceanic

The toxic effects of the composites of Fe^0 and Cu^0 with different percentages of CNTs were examined based on the activity of bacterial bioluminescence and seed germination. In terms of the EC50 values, the toxic effects of Cu^0 on bacterial bioluminescence and seed germination were approximately 2 and 180 times greater than that of Fe^0, respectively. The toxicity increased with increasing CNT content in the Cu-CNT mixtures for both organisms,whereas opposite results were observed with Fe-CNT mixtures. The mean toxic effects of Cu-CNT（6%） were approximately 1.3–1.4 times greater than that of Cu-CNT（0%）, whereas the toxic effects of Fe-CNT（6%） were approximately 2.1–2.5 times lower than that of Fe-CNT（0%） for both the bioluminescence activity and seed germination. The causes of this phenomenon are unclear at this point. More research will be needed to elucidate the mechanism of the toxicity of nano-mixture materials and the causes of the different patterns of toxicity with Cu-and Fe-CNT mixtures.

We demonstrate highly efficient multi-colored semitransparent perovskite solar cells that can create high angular tolerant controllable transmissive colors up to 60~, based on phase-compensated microcavities. The efficiency of the semitransparent colors was improved by impedance matching, which was enabled by placing a dielectric functional layer on top of traditional optical microcavities, with negligible influence on color pureness. The vast majority of the visible part of solar radiation is efficiently utilized for solar energy harvesting, achieving 10.47%, 10.66%, and 11.18% of efficiency for red, green, and blue （RGB） colored solar cells, respective136 while a very small proportion of the visible solar spectrum is used for structural coloration that can be readily tuned by altering the cavity medium thickness. The approach described herein can be suitable for a variety of applications such as display systems with ultra-low power consumption, highly efficient colorful solar panels, low-power wearable electronics, and energy-efficient optoelectronics.
