Enhancement of Catalytic Activity via Inevitable Reconstruction of the Ni-Mo Interface for Alkaline Hydrogen Oxidation.

The inevitable oxidation of nickel-metal-based catalysts exposed to the air will lead to instability and poor reproducibility of a catalytic interface, which is usually ignored and greatly hinders their application for the catalysis of alkaline hydrogen oxidation. The details on the formation of a world-class nickel-based HOR catalyst Ni-MoO/C-500 are reported via an interfacial reconstruction triggered by passive oxidation upon air exposure. Interfacial reconstruction, initiated with various Ni-Mo metal ratios and annealing temperature, can fine-tune the Ni-Mo interface with an increased work function and a reduced d-band center.

Development and validation of a new risk assessment model for immunomodulatory drug-associated venous thrombosis among Chinese patients with multiple myeloma.

Background: Individuals with multiple myeloma (MM) receiving immunomodulatory drugs (IMiDs) are at risk of developing venous thromboembolism (VTE), a serious complication. There is no established clinical model for predicting VTE in the Chinese population. We develop a new risk assessment model (RAM) for IMiD-associated VTE in Chinese MM patients.

Secondary perichondrium patch to enhance cartilage graft during endoscopic cartilage myringoplasty.

Objectives: The aim of this study was to explore the method of adding a secondary perichondrium patch to enhance the primary cartilage-perichondrium patch during endoscopic myringoplasty and to evaluate the effectiveness of this method in terms of healing rate and post-operative hearing of patients with poor prognostic factors (eustachian tube dysfunction, large perforations, subtotal perforations, and anterior marginal perforations).

Design: This retrospective study analyzed a total of 80 patients (36 females and 44 males, median age of 40.55 years) who had received a secondary perichondrium patch during endoscopic cartilage myringoplasty.

Effect of polyethylene glycol 400 on the pharmacokinetics and tissue distribution of baicalin by intravenous injection based on the enzyme activity of UGT1A8/1A9.

Baicalin (BG) is a bioactive flavonoid extracted from the dried root of the medicinal plant, Scutellaria radix (SR) (dicotyledonous family, Labiatae), and has several biological activities. Polyethylene glycol 400 (PEG400) has been used as a suitable solvent for several traditional Chinese medicines (TCM) and is often used as an excipient for the compound preparation of SR. However, the drug-excipient interactions between BG and PEG400 are still unknown.

Comparison of endoscopic and microscopic tympanoplasty in patients with chronic otitis media.

Background: To compare the results between type I tympanoplasty performed with transcanal endoscopic ear surgery (TEES) and microscopic ear surgery (MES) for treatment of chronic otitis media in a homogenous group of patients.

Methods: A retrospective study was performed in our department between January 2011 and January 2016 to review primary type I tympanoplasty cases with a subtotal perforation, an intact ossicular chain, a dry ear for at least 1 month, normal middle ear mucosa, and a follow-up period of at least 6 months post surgery. The adoption of TEES or MES was divided temporally (before and since 2013).

[Observation on the efficacy of Eustachian tube dilation hormone under the guidance of endoscope in the treatment of sudden deafness].

To evaluate the efficacy of Eustachian tube dilation hormone under the guidance of otoscope in the treatment of patients with sudden deafness. One hundred and seventy-six patients（185 ears） with sudden deafness treated by otorhinolaryngology head and neck surgery in Shaanxi Provincial People's Hospital from January 2020 to December 2020 were selected. According to the inclusion and exclusion criteria, 176 patients（185 ears） were randomly divided into control group（=86, 90 ears） and study group（=90, 95 ears）.

Novel LiSnO/g-CN Heterojunction With Enhanced Visible Light Photocatalytic Efficiency Toward Rhodamine B Degradation.

The design of highly efficient and stable photocatalysts to utilize solar energy is a significant challenge in photocatalysis. In this work, a series of novel heterojunction photocatalysts, LiSnO/g-CN, was successfully prepared via a facile calcining method, and exhibited superior photocatalytic activity toward the photodegradation of Rhodamine B solution under visible light irradiation as compared with pure LiSnO and g-CN. The maximum kinetic rate constant of photocatalytic degradation of Rhodamine B within 60 min was 0.

In Situ Construction of a MgSn(OH) Perovskite/SnO Type-II Heterojunction: A Highly Efficient Photocatalyst towards Photodegradation of Tetracycline.

Using solar energy to remove antibiotics from aqueous environments via photocatalysis is highly desirable. In this work, a novel type-II heterojunction photocatalyst, MgSn(OH)/SnO was successfully prepared via a facile one-pot in situ hydrothermal method at 220 °C for 24 h. The obtained heterojunctions were characterized via powder X-ray diffraction, Fourier-transform infrared spectroscopy, transmission electron microscopy, and ultraviolet-visible diffuse reflectance spectroscopy.

[The expression and clinical significance of pepsin and pepsinogen in patients with otitis media with effusion].

Objective: To analyze the role and significance of pepsin and pepsinogen in the pathogenesis of OME in children.

Method: Pediatric patients with otitis media aged 2-8 years who enrolled in our department of the hospital from May of 2012 to December of 2012 were set as experimental group (38 cases, 48 ears) which should be underwent tympanic membrane puncture/tube insertion. Meanwhile, pediatric patients waiting for cochlear implant without otitis media (10 ears), were set as control group.

Role of pepsin and pepsinogen: linking laryngopharyngeal reflux with otitis media with effusion in children.

Objectives/hypothesis: To analyze the relationship between laryngopharyngeal reflux (LPR) represented by pepsin and pepsinogen, and pathogenesis of otitis media with effusion (OME).

Study Design: Prospective case-control study.

Methods: Children with OME who required adenoidectomy and tympanostomy/tympanostomy tubes placement were enrolled in OME group, whereas children with adenoid hypertrophy (AH) who required adenoidectomy and individuals who required cochlear implantation (CI) were enrolled in AH and CI groups, respectively.

[A Systematic Review of Erlotinib for Advanced Non-small Cell Lung Cancer.].

Background: It was unclear whether advanced non-small cell lung cancer (NSCLC) patients could benefit from erlotinib therapy. This study was aimed to evaluate the efficacy and safety of NSCLC patients treated with erlotinib.

Methods: The relevant randomized controlled trials (RCT) were searched from VIP, CMB, CNKI, PubMed, EMBASE and The Cochrane Library.

[A meta analysis of gemcitabine plus platinum chemotherapy compared with single-agent chemotherapy in the treatment of non-small cell lung cancer].

Background And Objective: Whether gemcitabine plus platinum chemotherapy is superior to gemcitabine or platinum single-agent chemotherapy for patients with non-small cell lung cancer (NSCLC) is still in dispute, and the aim of this study is to evaluate the efficacy and safety of gemcitabine combining platinum chemotherapy for patients with NSCLC.

Methods: We searched relevant randomized controlled trials (RCTs) from VIP, CBM, CNKI, the Cochrane library, PUBMED and EMBASE. We traced the related references and experts in this field and communicated with other authors to obtain the information that has not been found.
