Silk Nanofibril-Palygorskite Composite Membranes for Efficient Removal of Anionic Dyes.

To develop membrane materials with good performance for water purification that are green and low cost, this work reports an organic-inorganic composite membrane composed of silk nanofibrils (SNFs) and palygorskite (PGS). To improve the stability of the the composite membrane, genipin was used as a crosslinking agent to induce the conformational transition of SNF chains from random coils to β-sheets, reducing the swelling and hydrolysis of the membrane. The separation performance can be adjusted by tailoring the component ratio of the nanomaterial.

Diagnosis and treatment of primary pulmonary enteric adenocarcinoma: Report of Six cases.

Background: Primary pulmonary enteric adenocarcinoma (PEAC) is a very rare subtype of invasive adenocarcinoma, and there have been no large studies on PEAC to date. Therefore, it is necessary to obtain much more information about the clinical and pathological features, diagnosis, differential diagnosis, and treatment of PEAC.

Case Summary: All clinical data of six patients with confirmed PEAC from 2013 to 2018 were collected, and data on diagnosis, differential diagnosis, and treatment of PEAC are discussed combined with all the associated literature.

Diagnose of occult bronchial foreign body: A rare case report of undetected Chinese medicine aspiration for 10 long years.

Background: Occult bronchial foreign body can be very difficult to diagnose early in an adult patient without acute symptoms. This report describes a rare case of undetected Chinese medicine "Coptis chinensis" aspiration for 10 long years.

Methods: A case was reported that a female patient complained of a 10-year history of productive cough.

The tracheobronchial foreign body in welder without the history of allotriophagy and foreign body aspiration.

The typical chest computed tomography (CT) finding of the arc welders is ill-defined micronodules diffusely distributed in the lung. We report a rare case of tracheobronchial foreign body in welder without the history of allotriophagy and foreign body aspiration. We used the CT and mineralogical analysis in diagnosis and the flexible fiberoptic bronchoscope in therapy.

Soil fertility, salinity and nematode diversity influenced by Tamarix ramosissima in different habitats in an arid desert oasis.

The aim of this paper was to assess the influence of tamarisk shrubs on soil fertility, salinity and nematode communities in various habitats located in an arid desert-oasis region in northwest China. Three habitats were studied: sand dune, riparian zone and saline meadow, where tamarisk shrubs have been established in recent decades in order to vegetation restoration used as desertification control and saline land rehabilitation projects and become the dominant plant community. The parameters measured include soil organic carbon (SOC), total nitrogen, available phosphorus (P) and potassium (K), pH, salt component, and nematode community characteristics.

[Clinical study of induced abortion of early-early pregnancy: an analysis of 10, 404 cases].

Objective: To evaluate the advantages and disadvantages of early-early pregnancy induced abortion (EPIA).

Methods: A total of 10 404 cases of EPIA performed at our hospital from January 1993 to December 2003 were retrospectively analyzed and compared with 9434 cases of common induced abortion (CIA). The amount of hemorrhage and operative duration, degree of pain, rate of induced-abortion syndrome, rate of incomplete abortion, menstrual changes and post-operative onset of Asherman's syndrome were observed and compared between 2 groups.

[Correlation of CerbB-2 to Ki-67 and P53 expressions in hormone-independent breast cancer].

Objective: To investigate the relation of CerbB-2 with Ki-67 and P53 expressions in hormone-independent breast cancer.

Methods: A total of 180 patients with breast cancer were examined for the positivity to estrogen receptor (ER) and progesterone receptor (PR), and subsequently divided into hormone-dependent group (positive for both ER and PR) and hormone-independent group (negative for both). CerbB-2, Ki-67 and P53 expressions were detected in these patients using an improved Envision immunohistochemical staining with the corresponding antibodies.

Effects of sandy desertified land rehabilitation on soil carbon sequestration and aggregation in an arid region in China.

The rehabilitation of sandy desertified land in semi-arid and arid regions has a great potential to increase carbon sequestration and improve soil quality. Our objective was to investigate the changes in the soil carbon pool and soil properties of surface soil (0-15 cm) under different types of rehabilitation management. Our study was done in the short-term (7 years) and long-term (32 years) desertification control sites in a marginal oasis of northwest China.

Pulmonary epithelioid haemangioendothelioma mimicking central lung cancer.

A 40-year-old woman was hospitalized for investigation of dry cough, dyspnoea, and pain and swelling in the large joints of the arms and legs. Chest CT revealed a left hilar mass with partial atelectasis in the apical segment of the left lower lobe. X-ray of the wrists, elbows, ankles and knee joints showed a periosteal reaction, associated with hypertrophic pulmonary osteoarthropathy.

[Construction, expression and characterization of recombinant fusion protein HSA-PTH (1-34) in Pichia pastoris].

Objective: To obtain recombinant fusion protein HSA (human serum albumin)-PTH(1-34) in Pichia pastoris.

Methods: HSA and PTH(1-34) cDNA were obtained with PCR and the DNA segments were cloned into vector pPIC9 with linker. The linearized plasmids were transformed GS115 competent cells treated with LiCl, and mut+ transformants were screened on MD plate.

Inhibitory effect of 1,8-cineol (eucalyptol) on Egr-1 expression in lipopolysaccharide-stimulated THP-1 cells.

Aim: To study the effects of 1,8-cineol (eucalyptol) on the expression of early growth response factor-1 (Egr-1) and NF-kappaB in the human monocyte THP-1 cell line stimulated by lipopolysaccharide (LPS).

Methods: The THP-1 cells were incubated with serial doses of 1,8-cineol (1, 10, and 100 mg/L, 30 min) before being stimulated with LPS (1 mg/L, 30 min). The localization of Egr-1 in the THP-1 cells was detected by immunofluorescence and a laser scanning confocal microscope.

Inhibition of expression of vascular endothelial growth factor and its receptors in pulmonary adenocarcinoma cell by TNP-470 in combination with gemcitabine.

Angiogenesis is required for solid tumor growth and facilitates tumor progression and metastasis. The inhibition effects of O-(chloroacetyl-carbamoyl) fumagillol (TNP-470), an angiogenesis inhibitor, and gemcitabine, a chemotherapeutic agent, on expression of growth factors were investigated using human pulmonary adenocarcinoma cell line, A549. The A549 cells were divided into four groups: control group, 10(-6) mg/ml gemcitabine treated group, 10(-4) mg/ml TNP-470 treated group and gemcitabine+TNP-470 treated group.

[Chronic necrotizing pulmonary aspergillosis: diagnosis and treatment].
