Effectiveness of Total Hip Arthroplasty Combined With Hip Braces for Hip Charcot Arthropathy.

Objective: Charcot arthropathy is characterized by varying degrees of sensory loss and rapidly progressive joint destruction. Historically, limited studies indicated that Charcot arthropathy of the hip joint may be a contraindication for total hip arthroplasty (THA). Yet, some recent studies have shown that good clinical results and acceptable survival rate.

Preliminary study of short-term outcomes and learning curves of robotic-assisted THA: comparison between closed platform robotic system and open platform robotic system.

Background: Both closed platform and open platform robotic-assisted total hip arthroplasty (THA) have recently been recommended as a viable treatment option for achieving accurate positioning of components. Yet, limited studies paid attention to the differences between the closed platform robotic system and the open platform robotic system. Hence, this study aimed to investigate clinical outcomes, radiographic outcomes, complication rates and learning curve of two systems.

Outcomes of dual mobility articulation total hip arthroplasty in ipsilateral residual poliomyelitis.

Background: Patients with poliomyelitis underwent total hip arthroplasty (THA) are known to be at higher risk of dislocation on account of muscular atrophy. This study aimed to investigate clinical outcomes, radiographic outcomes, complication rates, and survivorship of dual mobility THA in displaced femoral neck fractures of elderly with poliomyelitis.

Materials And Methods: We retrospectively included 17 patients (17 hips) with residual poliomyelitis who underwent THA with dual mobility articulation.

The role of routine postoperative laboratory tests following hip hemiarthroplasty for an elderly femoral neck fracture.

Background: Performing postoperative laboratory tests following joint arthroplasty is a regular practice. However, the role of routine postoperative laboratory tests in primary hip arthroplasty is currently in doubt. This study aimed to assess the role of routine postoperative laboratory tests for femoral neck fractures in elderly patients who underwent hip hemiarthroplasty and to evaluate the risk factors for postoperative laboratory testing abnormalities and related interventions.

[Herbalogical study on olibanum(Ruxiang)].

As a representative foreign medicinal material, olibanum(Ruxiang) was imported to China since the Qin and Han Dynasties. Olibanum was first described as a medicinal by the name "Xunluxiang" in Miscellaneous Records of Famous Physicians(Ming Yi Bie Lu). This study investigated historical records on olibanum and conducted the herbalogical study.

[Herbalogical study on original plant and medicinal and edible values of Citri Sarcodactylis Fructus].

Citri Sarcodactylis Fructus is a both medicinal and edible species specified by the China Ministry of Health, with a long history in China. According to the ancient monographs about materia medica, it was found that the records of the Citri Sarcodactylis Fructus on the original plants were confused. This paper reviewed the ancient monographs about materia medica, and made a summarization and textual research on the name, origin, habitat, processing methods, medicinal properties and clinicacy efficacy of Citri Sarcodactylis Fructus based the comprehensive analysis on modern literatures and authoritative books of Chinese herbal medicine.

Transgelin interacts with PARP1 in human colon cancer cells.

Background: Transgelin, an actin-binding protein, is associated with cytoskeleton remodeling. Findings from our previous studies demonstrated that transgelin was up-regulated in node-positive colorectal cancer (CRC) versus node-negative disease. Over-expression of affected the expression of 256 downstream transcripts and increased the metastatic potential of colon cancer cells in vitro and in vivo.

[Historical evolution of Coicis Semen processing methods].

Coicis Semen is widely used as a raw material which can be used as both medicine and food among people. According to the ancient monographs on materia medica and relevant documents on the processing specifications in various provinces and cities, herba logical study on the historical evolution of the processing methods of Coicis Semen was conducted in this paper from the aspects of collecting and processing methods of Coicis Semen, the processing methods in the past dynasties and the nature, flavour and efficacy of Coicis Semen. The results showed that the processing methods of Coicis Semen recorded in monographs on materia medica mainly included stir-frying, glutinous rice stir-frying, salt processing(including salt cooking and salt stir-frying), stir-frying with the earth scraped from the wall facing east, and ginger juice stir-frying, etc.

Hemiarthroplasty compared with internal fixation for treatment of nondisplaced femoral neck fractures in elderly patients: a retrospective study.

Introduction: Internal fixation (IF) with cannulated screws is the most widely accepted operation method for nondisplaced femoral neck fractures (FNFs) in elderly patients. However, there were higher rate of reoperation, severe complications and poorer functional outcomes reported in these patients treated with IF. The purpose of this research is to compare the prognosis, complications, reoperation and mortality of bipolar hemiarthroplasty (HA) with IF of cannulated screws in elderly patients.

Atomic Force Microscopy-Based Nanoscopy of Chondrogenically Differentiating Human Adipose-Derived Stem Cells: Nanostructure and Integrin β1 Expression.

Integrin β1 is known to be involved in differentiation, migration, proliferation, wound repair, tissue development, and organogenesis. In order to analyze the binding probability between integrin β1 ligand and cluster of differentiation 29 (CD29) receptors, atomic force microscopy (AFM) was used to detect native integrin β1-coupled receptors on the surface of human adipose-derived stem cells (hADSc). The binding probability of integrin β1 ligand-receptor interaction was probed by integrin β1-functionalized tips on hADSc during early chondrogenic differentiation at the two-dimensional cell culture level.

[The relationship between PMI and concentration of potassium ion and sodium ion in swine aqueous humor after death].

Objective: To explored the relationship between the concentration of potassium ion as well as sodium ion in the aqueous humor and post-mortem interval (PMI).

Methods: The concentrations of potassium ion and sodium ion in the aqueous humor of swine within 48 h after death at 4 degrees C and 28 degrees C were detected using Z-500 atomic absorption spectrophotometer.

Results: The concentrations of potassium ion and sodium ion in aqueous humor of isolated swine eyeballs within 48 h after death when the environmental temperature was 4 degrees C were significantly related to PMI.

[Survivin and COX-2 expressions in giant cell tumor of bone and their relation to the prognosis].

Objective: To investigate the expression of survivin and COX-2 in giant cell tumor of bone (GCT) and explore the prognostic factors for GCT.
