A prediction model of elderly hip fracture mortality including preoperative red cell distribution width constructed based on the random survival forest (RSF) and Cox risk ratio regression.

Unlabelled: An independent correlation between pre-RDW and 1-year mortality after surgery in elderly hip fracture can be used to predict mortality in elderly hip fracture patients and has predictive significance in anemia patients. With further research, a treatment algorithm can be developed to potentially identify patients at high risk of preoperative mortality.

Introduction: Red blood cell distribution width (RDW) is an independent predictor of various disease states in elderly individuals, but its association with the prognosis of elderly hip fracture patients is controversial.

The transcription factor masculinizer in sexual differentiation and achieved full functional sex reversal in prawn.

Some Zinc finger (ZnF) proteins are required for masculinization in silkworms. In the present study, a masculinizer gene (Mr-Masc) with multi-tissue expression is identified in the freshwater prawn . The Mr-Masc is clustered into a separate branch with ZnF proteins from decapoda by phylogenetic tree analysis.

Full Functional Sex Reversal Achieved Through Silencing of Gene in : Production of All-Male Monosex Freshwater Prawn.

The freshwater prawn is one kind of important economic aquaculture species and displays remarkable sexual dimorphism. The molecular mechanism of sexual differentiation in has been primarily unraveled through the research efforts of the androgenic gland and its related genes. However, the understanding of conserved genes involved in the molecular mechanism underpinning sex determination and sexual differentiation of is still fragmentary.

[Efficiency and Kinetics of Triclosan Degradation in Aqueous Solution by UV/Sodium Persulfate].

UV activated sodium persulfate was employed to remove triclosan (TCS) in aqueous solution. The effects of several factors such as UV wavelength,UV intensity,sodium persulfate dosage,pH value,and HA on TCS degradation were investigated. The second-order rate constants of free radicals (·OH, SO) reacting with TCS and their contributions to TCS removal were determined,respectively.

Abnormal expression of FLOT1 correlates with tumor progression and poor survival in patients with non-small cell lung cancer.

Recent studies have revealed that flotillin-1 (FLOT1) plays important roles in cancer progression. However, the role of FLOT1 in development and progression of non-small cell lung cancer (NSCLC) remains largely unknown. The objective of the current study was to investigate the expression pattern and clinicopathological significance of FLOT1 in patients with NSCLC.

[Clinical study on improving decreased gastrointestinal motility of post-operative esophageal cancer patients by unblocking the interior and purgation method].

Objective: To observe the clinical effect of unblocking the interior and purgation method on improving decreased gastrointestinal motility of post-operative esophageal cancer patients, and to study its mechanisms.

Methods: 60 patients with post-operative esophageal cancer were randomly assigned to two groups, the treatment group and the control group, 30 in each group. Routine therapies were given to the two groups.

[Comparison of the characteristics in recurrence and metastasis between bronchioloalveolar carcinoma and other lung adenocarcinomas].

Background & Objective: The histological definition of bronchioloalveolar carcinoma (BAC) has been changed recently by the revised World Health Organization (WHO) classification. Although bronchioloalveolar carcinoma is a subtype of lung adenocarcinoma, its biological features are better than those of other lung adenocarcinomas. This study was to analyze differences in metastatic activity between bronchioloalveolar carcinoma and other lung adenocarcinomas.

[Bronchial and pulmonary arterial sleeve resection and reconstruction in the treatment of central NSCLC].

Objective: To evaluate the indications and surgical procedure of bronchial and pulmonary artery sleeve resection for patients with centrally located non-small cell lung cancer, and how to prevent complications.

Methods: From July 1989 to Aug 2000, 32 cases of central NSCLC were treated with bronchial and pulmonary arterial sleeve resection and reconstruction. The results were retrospectively analyzed.
