Evaluating Docking Site Local Hematoma Formation and Blood Flow on its Healing Using the Accordion Technique at the End of Tibial Bone Transport.

Objective: At present, due to the lack of early observation methods, the effect of the 'accordion' technique on the treatment of nonunion of the docking site varies greatly. In this study, color Doppler ultrasound was used to observe the docking site's local changes and investigate the relationship between local microenvironment changes and bone healing after the accordion technique.

Methods: 30 patients with tibial bone transport treated at the Department of Orthopedics, Second Hospital of Shanxi Medical University, from May 2018 to June 2022, were analyzed retrospectively.

Pulmonary fibrosis insights and therapy targets from disease models and administration of the lipophilic diterpene, sodium tanshinone IIA sulfonate: Review and meta-analysis.

Pulmonary fibrosis (PF) is a chronic and progressive pulmonary interstitial disease of unknown etiology and is also a sequela in severe patients with the Coronavirus Disease 2019 (COVID-19). Seven databases were systematically searched to evaluate the preclinical evidence of Tanshinone IIA (Tan IIA) on PF. The quality of the included studies was assessed using a 10-item risk of bias tool, and data were analyzed using RevMan 5.

Subwavelength dichroic demultiplexer based on double Fabry-Perot cavities.

Plasmonic demultiplexers hold promise for the realization of the subwavelength and high-splitting ratio dichroic splitter and have a wide range of applications from optical communication, and manipulation to ultrafast data treatment. However, this vision has not been realized for a long time due to lacking the suitable splitting structure design, which limits its further development of integrated photonic circuits. Here, we demonstrate a plasmonic demultiplexer with subwavelength feature size (0.

Objective: To explore the relationship between obesity and lumbar disc herniation in adolescents.

Methods: From January 2018 to July 2019, 581 patients (337 males, 244 females) with lumbar disc herniation were included in the surgical treatment. According to the age classification standard of the World Health Organization, they were divided into two groups:the adolescent group, 235 cases (145 males, 90 females), age 14 to 44 years old with an average of (32.

[Limited open reduction and intramedullary fixation for the treatment of refractory femoral subtrochanteric fractures].

Objective: To explore the surgical technique and clinical effect of limited open reduction and intramedullary fixation assisted with orthopedic traction bed for the treatment of femoral subtrochanteric fractures.

Methods: From July 2015 to October 2017, 12 patients with femoral subtrochanteric fractures were treated including 9 males and 3 females with an average age of 44 years old ranging from 33 to 67 years old. Among them, 10 cases were on the left trochanter and 2 on the right, and there were 8 cases of highly fall injury and 4 cases of traffic accident injury.

[Meta-analysis of the efficacy and safety of PFNA and InterTAN for the treatment of intertrochanteric fractures].

Objective: To system evaluate the clinical effect and safety of PFNA and InterTAN internal fixation methods for femoral intertrochanteric fracture.

Methods: According to the Cochrane systemic analysis method, randomized controlled trials and quasi-randomized controlled trials which were about the comparison of PFNA and InterTAN for intertrochanteric fracture were collected from Cochrane Library(2017, issue 4), PubMed (January, 2003-May, 2017), Wanfang Med Online (January, 2003-May, 2017) and China Academic Journals Full-text Database(January, 2003-May, 2017) by computer searching. Cross-checking was done after assessing the quality of the included trials and extracting the data by two reviewers independently.

Anti-Cancerous Potential of Polysaccharide Fractions Extracted from Peony Seed Dreg on Various Human Cancer Cell Lines Via Cell Cycle Arrest and Apoptosis.

In this study, four homo/heterogenous polysaccharides (HBSS, CHSS, DASS, and CASS) extracted from peony seed dreg with respective molecular weights of 3467, 4677, 229, and 56 kDa were evaluated for anti-cancerous attributes in prostate cancer cells (Pc-3), colon cancer cells (HCT-116), human breast cancer cells (MCF-7), cervical cancer (Hela cells) and human embryonic kidney 293 (HEK 293) cells as control. Among them, CASS and DASS extracted by alkali, consisted of 34.43% , 26.

Structure revision of aspergicin by the crystal structure of aspergicine, a co-occurring isomer produced by co-culture of two mangrove epiphytic fungi.

The structure of aspergicin (1), an antibacterial alkaloid produced by co-culture of two marine-derived mangrove epiphytic fungi, were revised by the co-occurring isomer named as aspergicine (2), whose structure was determined on the basis of spectroscopic analysis and X-ray crystallography.

Thermal, emulsifying and rheological properties of polysaccharides sequentially extracted from Vaccinium bracteatum Thunb leaves.

Plant polysaccharides are widely used in food industry as thickening and gelling agents and these attributes largely depend on their thermal, emulsifying and rheological properties. As known, the extraction methods always bring about the diversification of property and functions of polysaccharides. Thus, the Vaccinium bracteatum Thunb leaves polysaccharides (VBTLP) were sequentially extracted using hot buffer (HBSS), chelating agent (CHSS), dilute alkaline (DASS) and concentrated alkaline (CASS).

The rheological properties of polysaccharides sequentially extracted from peony seed dreg.

The peony seed dreg polysaccharides (PSDPs) were sequentially extracted using hot buffer (HBSS), chelating agent (CHSS), dilute alkaline (DASS) and concentrated alkaline (CASS). The rheological properties of PSDPs were investigated by steady-shear and oscillatory rheological measurements. The four PSDPs fractions in solution exhibited typical non-Newtonian and shear-thinning behavior.

Physicochemical properties and antioxidant activities of polysaccharides sequentially extracted from peony seed dreg.

The sequential extraction of peony seed dreg polysaccharides (PSDP) with hot buffer (HBSS), chelating agent (CHSS), dilute alkaline (DASS) and concentrated alkaline (CASS) yielded four different polysaccharide fractions. Based on their absorptions at 3600-3200cm(-1) and 1200-800cm(-1), these fractions were confirmed to be polysaccharides. The properties of four PSDPs displayed some slight differences.

Stepwise synthesis of cubic Au-AgCdS core-shell nanostructures with tunable plasmon resonances and fluorescence.

Cubic Au-AgCdS core-shell nanostructures were synthesized through cation exchange method assisted by tributylphosphine (TBP) as a phase-transfer agent. Among intermediate products, Au-Ag core-shell nanocubes exhibited many high-order plasmon resonance modes related to the special cubic shape, and these plasmon bands red-shifted along with the increasing of particle size. The plasmon band of Au core first red-shifted and broadened at the step of Au-Ag₂S and then blue-shifted and narrowed at the step of Au-AgCdS.
