The complete chloroplast genome of .

(Linn.) 1936 is a high-quality perennial forage in Loess Plateau of China. In this study, we sequenced and characterized the complete chloroplast genome of , which was a circular DNA of 138,316 bp in length, including a large single copy (LSC) region of 80,226 bp, a small single copy (SSC) region of 12,526 bp, and the circular DNA was separated by a pair of identical inverted repeat regions (IRs) of 22,782 bp each.

Facile Synthesis of Highly Dispersed and Well-Alloyed Bimetallic Nanoparticles on Oxide Support.

Supported alloy catalysts play a pivotal role in many heterogeneous catalytic processes of socioeconomic and environmental importance. But the controlled synthesis of supported alloy nanoparticles with consistent composition and tight size distribution remains a challenging issue. Herein, a simple yet effective method for preparation of highly dispersed, homogeneously alloyed bimetallic nanoparticles on oxide supports is reported.

Uncovered stent insertion for isolated superior mesenteric artery dissection.

The aim of this study is to describe our clinical outcomes in isolated superior mesenteric artery dissection (SMAD) patients that underwent uncovered stent insertion.Between January 2016 and August 2019, consecutive isolated SMAD patients at our center were treated via uncovered stent insertion. Both short- and long-term outcomes in these patients were analyzed.

Relationship between Maternal PBMC HBV cccDNA and HBV Serological Markers and its Effect on HBV Intrauterine Transmission.

Objective: To investigate the relationship between maternal peripheral blood mononuclear cells (PBMC) hepatitis B virus (HBV) covalenty closed circular deoxyribonucleic acid (cccDNA) and other HBV serological markers and its effects on HBV intrauterine transmission.

Methods: We enrolled 290 newborns and their hepatitis B surface antigen (HBsAg) positive mothers. HBV cccDNA in PBMC and HBV DNA in serum were detected by a real-time PCR-TaqMan probe while HBV serological markers were detected with an electrochemiluminescence immunoassay.

Direct observation of solid-state reversed transformation from crystals to quasicrystals in a Mg alloy.

Phase transformation of quasicrystals is of interest in various fields of science and technology. Interestingly, we directly observed unexpected solid-state epitaxial nucleation and growth of Zn6Mg3Y icosahedral quasicrystals in a Mg alloy at about 573 K which is about 300 K below the melting point of Zn6Mg3Y, in contrast to formation of quasicrystals through solidification that was usually found in many alloys. Maximizing local packing density of atoms associated with segregation of Y and Zn in Mg adjacent to Mg/Zn3MgY interfaces triggered atomic rearrangement in Mg to form icosahedra coupled epitaxially with surface distorted icosahedra of Zn3MgY, which plays a critical role in the nucleation of icosahedral clusters.

[TCM societies in Shanghai during the first half of the 20(th) century].

In the first half of the 20(th) century, with the introduction of western academic thought and the assemblage of TCM doctors of different factions, the variety of cultures provided an ideological and academic background for TCM societies in Shanghai in modern times. Under the pressure of banning and exclusion, protective measures taken by the TCM circles promoted the establishment of TCM societies. The establishment and development of TCM societies in Shanghai in modern times included four stages - the embryonic stage (1903 - 1911), the development stage (1912 - 1926), the struggling stage (1927 - 1937) and the recovery stage (1938 - 1949).

[Analysis of medical thoughts of LU Yuan-lei-relationship with Japanese Kampo medicine].

LU Yuan-lei (1894 - 1955) is the representative of Chinese and Western Medicine Convergence School in modern times. He is also the advocate of scientization of Traditional Chinese Medicine (TCM). TCM scientization is the refleetion of influence of Kampo medicine in modern China.

[Comparison of academic viewpoints between Yun Tie-qiao and Lu Yuan-lei].

Both Yun Tie-qiao and Lu Yuan-lei are medical professionals coming from the literary field with versatile and in-depth knowledge and extensive experience in medical education and clinical practice, all closely related to modern TCM development. Yun, the elder, insisted on reforming TCM and was early to advocate the academic idea of amalgamating western and traditional Chinese medicine; while Lu, the younger, insisted on the idea of "scientizing TCM" and was the representative of amalgamating western and traditional Chinese medicine in the later stage. They shared many common viewpoints, including venerating Zhang Zhongjing, stressing exogenous cold pathogens, advocating reformation and amalgamation of western medicine and TCM and objecting to the abolishment of TCM.

Increased liver-infiltrating CD8+FoxP3+ regulatory T cells are associated with tumor stage in hepatocellular carcinoma patients.

Hepatocellular carcinoma (HCC) is the most common primary malignant tumor of the liver, and patients who are diagnosed with this tumor typically have a poor prognosis. The suppressive effects of CD4(+)FoxP3(+) regulatory T cells on antitumor immune response in HCC have been studied in great detail. CD8(+)FoxP3(+) regulatory T cells have recently been detected in tumors; however, the role of CD8(+)FoxP3(+) regulatory T cells in HCC is still unknown.

[Liver transplantation for treating hepatocellular carcinoma].

Objective: To evaluate the role of orthotopic liver transplantation (OLT) in treating hepatocellular carcinoma (HCC).

Methods: Data of 92 consecutive orthotopic liver transplantations (OLTs) performed during January 1999 and February 2005 at our institution were analyzed.

Results: Of the 92 recipients, 8 HCC patients were stage I, 13 were stage II, 12 stage III and 59 stage IV (UICC TNM staging system).
