Bian stone hot ironing can harmonize stomach qi, nourish qi and assist yang, clear the internal organs and clear turbidity, regulate intestinal qi circulation, and promote qi stagnation.

Preparation of nitrogen doped hyper-crosslinked polymer-based hard carbon for high performance Li/Na battery anode.

Hyper cross-linked polymers (HCPs), as a key precursor of hard carbon (HC) anode materials, stand out because of their capacity for molecular-scale structural design and comparatively straightforward preparation techniques, which are not seen in other porous materials synthesized procedure. A novel synthesis method of HCPs is developed in this paper, which is through the incorporation of functional macromolecules, the structural control and heteroatom doping of the product has been achieved, thus augmenting its electrochemical performance in batteries. In this work, carbonized tetraphenylporphyrin zinc (TPP-Zn) doped HCP-based hard carbon (CTHCP) with stable structure was prepared by Friedel-Crafts reaction and carbonization by using naphthalene and trace TPP-Zn as monomers, dimethoxybenzene (DMB) as crosslinking agent and FeCl as catalyst.

Preoperative Anemia Is a Predictor of Worse Postoperative Outcomes Following Open Pancreatoduodenectomy: A Propensity Score-Based Analysis.

Methods: We analyzed the data of consecutive patients undergoing open pancreatoduodenectomy with a complete record of preoperative hemoglobin, at two pancreatic centers in China between 2015 and 2019.

Emerging Role of Exosomal-Derived Long Noncoding RNAs in Human PDAC.

Background: The incidence and mortality of pancreatic ductal adenocarcinoma (PDAC) are increasing recently. Most patients with PDAC are diagnosed at advanced stage because of the high invasiveness of cancer cells and the lack of typical early symptoms. Therefore, early diagnosis of PDAC is very important to improve the prognosis.

Withaferin A induces mitochondrial-dependent apoptosis in non-small cell lung cancer cells via generation of reactive oxygen species.

Purpose: Withaferin A (WA) is a bioactive lactone, isolated from natural sources, mainly found in Withania somnifera, and was known to be highly effective against a variety of tumor cells both in vitro and in vivo. Accumulating experimental evidence suggests the involvement of reactive oxygen species (ROS) in WA-mediated cytotoxicity against cancer cells. Hence, the purpose of this study was to investigate the effect of WA in non-small cell lung cancer (NSCLC) cells and also the role of ROC in WA-mediated cytotoxicity.

A meta-analysis of interlaminar minimally invasive discectomy compared to conventional microdiscectomy for lumbar disk herniation.

A meta-analysis was conducted to evaluate the evidence that compared the safety and efficacy of interlaminar minimally invasive discectomy (ILMI) and conventional microdiscectomy (MD) for treating lumbar disk herniation (LDH) patients and to develop GRADE based recommendations for using the procedures to treat LDH. Eleven studies, encompassing 1012 patients, met the inclusion criteria. Overall, the results of the meta-analysis indicated that there were significant differences between the two groups in blood loss (SMD=-0.
