Radiofrequency ablation (RFA) is the current gold standard for palliative care of non-small cell lung cancer (NSCLC). Pain relief for advanced metastases of NSCLC is notoriously difficult. Combined RFA therapy may be more effective than palliating therapy alone in management of painful metastatic disease. The effects of RFA on quality of life, particularly pain, as well as long-term outcome studies are not well studied. To study the effectiveness of percutaneous minimal invasive RFA in pain management of NSCLC patients with metastatic chest wall, vertebral bodies and rib, and periphery lung nodule.

Forty patients with 59 tumors underwent percutaneous computed tomography (CT) or ultrasound-guided RFA for pain management over a 4-week observation. Forty patients were referred to ablation because of persistent severe pain despite using analgesics, chemotherapy or radiotherapy. The tumors were located in the periphery lung, or metastatic to chest wall, rib or vertebral body. Quantitative pain scale values werith average OS of 6.5 months in the further follow-up.

Percutaneous RFA resulted in sustained pain relief from in most advanced NSCLC patients with intractable pain and resistant to chemotherapy or radiotherapy. The effect of RFA was satisfactory, and patients can obtain a better life quality with less pain and complications.

To explore computed tomography (CT) characteristics of the 2019 novel coronavirus (COVID-19) pneumonia and explore variations among the different clinical types.

Clinical and CT imaging data of 43 patients diagnosed with COVID-19 in our hospital and the cooperative hospital between January 15-30, 2020 were collected (27 male and 16 female). Patients were classified as common type (26 cases, 60%), severe type (14 cases, 33%) or critical type (three cases, 7%) according to the new coronavirus pneumonia treatment scheme (sixth edition). Patient clinical data and CT images were analyzed and evaluated.

Fever was the main symptom in common type COVID-19 cases (23/26, 88.46%). Both severe and critical type COVID-19 patients had fever and cough symptoms, and dyspnea was observed in all three critical COVID-19 patients. CT manifestations in the common type COVID-19 cohort were bilateral involvement (20/26, 71%), multiple lesions (14/26, 54%), ground-glass density shadow (17/26, 65%), and some cases were accompanssment of the severity of COVID-19.
To evaluate the efficacy of different pharmacological interventions, with emphasis on monoclonal antibodies (McAbs) for the treatment of postmenopausal osteoporotic women.

A search of PubMed, Google Scholar, Embase, and the Cochrane Library, as well as China National Knowledge Infrastructure (CNKI) was performed. Data were collected and pooled using Bayesian network meta-analysis (NMA), which conducts both direct and indirect comparisons. The primary outcome was the percentage change in bone mineral density (BMD) in the lumbar spine from baseline to 1 year of treatment. All drugs were ranked based on the surface under the cumulative ranking area (SUCRA). Furthermore, the heterogeneity, consistency, and publication bias of the enrolled literature were assessed.

There were 14 randomized controlled trials (RCTs) consisting of 4,881 participants included to compare 11 interventions. Compared with that of a placebo, all the 10 selected therapies showed significant efficacy through changes in BMD ranging from 6.0% to 19.0% (all P<0.01). As the SUCRA values indicated, the therapeutic performance of antibody drugs was better than that of the conventional chemical agents, and blosozumab was the best choice (SUCRA 99.2%) to improve lumbar spine BMD.

Novel McAb treatments achieved better therapeutic effects in the treatment of postmenopausal osteoporosis (PMO), especially blosozumab. Further trials are needed to investigate and optimize the delivery strategy of McAbs.

However, for patients with tracheal stenosis, management of one lung ventilation (OLV) in the anesthesia is still full of challenges due to mismatching between the trachea lumen and tracheal tube diameter. In the past, a small single-lumen tube (SLT) combined with an endobronchial pediatric BB or extraluminal detached BB of a uninvent obtained successful OLV in patients with tracheal stenosis. Additionally, nonintubated tracheal and surgical pneumothorax may work. We first report an interesting case of a 65-year-old man with a history of an upper left lobe nodule in the lung and tracheotomies. A chest computed tomographic (CT) scan showed the middle of the trachea was severely narrowed. We used a minor SLT and extraluminal BB and acquired optimal collapse of the left lung. He accepted video-assisted thoracoscopic lobectomy of an upper left lobe under general anesthesia. After both BB and SLT were removed, the patient did not present dyspnea or airway injury. The patient recovered well and was discharged from the hospital a week after surgery. This method, a minor SLT combined with extraluminal BB, is convenient for sputum suction and fiber optic bronchoscope examination, moreover, it is an option for OLV in severe tracheal stenosis cases.Additive manufacturing (AM) of orthopedic implants is growing in popularity as it offers almost complete design flexibility and freedom, meaning complex geometries mimicking specific body parts can be easily produced. Novel composite materials with optimized functionalities present opportunities for 3D printing osteoconductive implants with desirable mechanical properties. Standard metals for bone implants, such as titanium and its alloys, are durable and nontoxic but lack bioactivity. Bioactive glasses promote strong bone formation but are susceptible to brittle failure. Metal-bioactive glass composites, however, may combine the mechanical reliability of metals with the bone-bonding ability of bioactive glasses, potentially reducing the incidence of implant failure. Processing such composites by AM paves the way for producing unprecedented bespoke parts with highly porous lattices, whose stiffness can be tailored to meet the mechanical properties of natural bone tissue. This Perspective focuses on titanium-bioactive glass composites, critically discussing their processability by AM and highlighting their potential as a next-generation implantable biomaterial.The aliphatic Claisen rearrangement of allyl vinyl ether has attracted great interest for its broad applications in chemical synthesis and biosynthesis. Although it is well agreed that this reaction proceeds via a concerted, "chair-like" transition state, certain inconsistencies of kinetic isotope effect (KIE) data between experimental measurements and theoretical simulations or between independent experiments indicate that the nature and mechanism of this important reaction need to be investigated in more detail. In order to verify two independent sets of experimental data, we present theoretical calculations on heavy-atom KIE values of alipahtic Claisen rearrangement, using our recently developed path-integral method with the second-order Kleinert's variational perturbation theory, which goes beyond the traditional method for computing KIE values by employing the Bigeleisen equation. Amazingly, the results demonstrate that both sets of experimental measurements are correct, while the inconsistency originates from the fact that the aliphatic Claisen rearrangement undergoes similar but different mechanisms in gas and solution phases. Different experimental conditions will alter the actual reactant state by tuning the population distribution of reactant conformers. According to the comparison between experimental and theoretical results, a more clear reaction mechanism of aliphatic Claisen rearrangement is revealed.We used yeast proteome microarrays (∼5800 purified proteins) to conduct a high-throughput and systematic screening of PI5P-interacting proteins with PI5P-tagged fluorescent liposomal nanovesicles. Lissamine rhodamine B-dipalmitoyl phosphatidylethanol was incorporated into the liposome bilayer to provide the nanovesicles with fluorescence without any encapsulants, which not only made the liposome fabrication much easier without the need for purification but also improved the chip-probing quality. A special chip assay was washed very gently without the traditional spin-dry step. Forty-five PI5P-interacting proteins were identified in triplicate with this special chip assay. Subsequently, we used flow cytometry to validate these interactions, and a total of 41 PI5P-interacting proteins were confirmed. Enrichment analysis revealed that these proteins have significant functions associated with ribosome biogenesis, rRNA processing, ribosome binding, GTP binding, and hydrolase activity. Trametinib purchase Their component enrichment is located in the nucleolus. The InterPro domain analysis indicated that PI5P-interacting proteins are enriched in the P-loop containing nucleoside triphosphate hydrolases domain (P-loop). Additionally, using the MEME program, we identified a consensus motif (IVGPAGTGKSTLF) that contains the Walker A sequence, a well-known nucleotide-binding motif. Furthermore, using a quartz crystal microbalance, both the consensus motif and Walker A motif showed strong affinities to PI5P-containing liposomes but not to PI5P-deprived liposomes or PI-containing liposomes. Additionally, the glycine (G6) and lysine (K7) residues of the Walker A motif (-GPAGTG6K7S-) were found to be critical to the PI5P-binding ability. This study not only identified an additional set of PI5P-interacting proteins but also revealed the strong PI5P-binding affinity (Kd = 1.81 × 10-7 M) of the Walker A motif beyond the motif's nucleotide-binding characteristic.Sulfidation can enhance both the reactivity and selectivity (i.e., electron efficiency, εe) of zero-valent iron (ZVI) in contaminant removal, which may make this technology cost-effective for a wider range of water treatment applications. However, current sulfidation methods involve either hazardous or unstable sulfidation agents (e.g., Na2S, Na2S2O3, and Na2S2O4) or energy-intensive preparations (e.g., mechanochemical sulfidation with elemental sulfur). In this study, we demonstrate that very efficient sulfidation of microscale ZVI (mZVI) can be achieved at all S/Fe molar ratios (∼100% sulfidation efficiency, εs) simply by direct reaction between elemental sulfur (S0) and ZVI in an aqueous suspension at ambient temperature. In comparison, the εs values obtained using Na2S, Na2S2O3, or Na2S2O4 as the sulfidation agents were only ∼23, ∼75, and ∼38%, respectively. The sulfidated mZVI produced using the new method reacts with trichloroethylene (TCE) with very high rates and electron efficiencies rate constants and electron efficiencies were 800- and 79-fold higher than those of the unsulfidated mZVI.
