#1
Zhiwei Wang, Jianan Ren, Gefei Wang, Qinjie Liu, Kun Guo, Jieshou Li
BACKGROUND Diabetes mellitus (DM) is a critical medical problem that can make people more likely to develop infectious complications, even sepsis. However, the influence of DM on the outcomes of septic patients is still controversial. Thus, we conducted the present meta-analysis to investigate whether DM worsens outcomes of septic patients. MATERIAL AND METHODS We searched studies from PubMed, Embase, and Cochrane Library databases from 1966 to July 1, 2016. The primary outcome we chose was 28-day or 30-day mortality or in-hospital mortality...

BACKGROUND To evaluate the incidence of preoperative anemia and its prognostic role in patients with urinary bladder cancer (BC). MATERIAL AND METHODS A total of 317 patients diagnosed with BC were enrolled in this retrospective cohort study. Univariate and multivariate analysis was used to identify independent prognostic factors and Kaplan-Meier survival analysis was applied to examine the influence of anemia on survival. RESULTS 109 patients (34.4%) were anemic with a median preoperative hemoglobin of 114 g/L (interquartile range 104 to 122...

BACKGROUND Recovery from post-stroke aphasia is a long and complex process with an uncertain outcome. Various interventions have been proposed to augment the recovery, including constraint-induced aphasia therapy (CIAT). CIAT has been applied to patients suffering from post-stroke aphasia in several unblinded studies to show mild-to-moderate linguistic gains. The aim of the present study was to evaluate the neuroimaging correlates of CIAT in patients with chronic aphasia related to left middle cerebral artery stroke...

BACKGROUND With the advances in imaging technologies, multi-slice spiral computed tomography (MSCT) has demonstrated superiority in the diagnosis and staging of colorectal carcinoma. In the current study, preoperative TNM staging of colorectal carcinoma by using MSCT was conducted and compared with the corresponding postoperative pathological examination findings, in order to evaluate the accuracy of preoperative MSCT for TNM staging. MATERIAL AND METHODS Combinations of biphasic or triphasic enhanced-phase MSCT scans were obtained for 76 patients with colorectal carcinoma, and the TNM stage was determined based on imaging reconstruction from various angles and perspectives to display the size, location, and affected range of tumors...

BACKGROUND It has been reported that trifluoperazine (TFP) inhibits proliferation of cancer cells, however, the effects of TFP in renal proliferation diseases are still unclear. This study examined the effects of TFP on proliferation of human renal mesangial cells and analyzed the underlying mechanisms. MATERIAL AND METHODS Cell proliferation in vivo was determined by HE staining, immunohistochemistry of proliferating cell nuclear antigen (PCNA), and Western blot analysis (Ki-67 and PCNA). Effects of different TFP concentrations and treatment duration on cell proliferation and cell cycle were analyzed using the MTT assay and flow cytometry...

The lung is one of several moderately radiosensitive organs. Radiation-induced lung injury (RILI), including acute radiation pneumonitis and chronic radiation-induced pulmonary fibrosis, occurs most often in radiotherapy of lung cancer, esophageal cancer, and other thoracic cancers. Clinical symptoms of RILI include dry cough, shortness of breath, chest pain, fever, and even severe respiratory failure and death. The occurrence of RILI is a complex process that includes a variety of cellular and molecular interactions which ultimately leads to large fibroblast accumulation, proliferation, and differentiation, resulting in excessive extracellular matrix deposits, causing pulmonary fibrosis...

Anterior glenohumeral dislocation affects about 2% of the general population during the lifetime. The incidence of traumatic glenohumeral dislocation ranges from 8.2 to 26.69 per 100 000 population per year. The most common complication is recurrent dislocation occurring in 17-96% of the patients. The majority of patients are treated conservatively by closed reduction and immobilization in internal rotation for 2-3 weeks. However, no clear conservative treatment protocol exists. Immobilization in external rotation can be considered an alternative...

BACKGROUND Paeoniflorin is a monoterpene glycoside extracted from the roots of Paeonia lactiflora and is used in Chinese herbal medicine to treat hyperlipidemia. The aim of this study was to evaluate the effects of an enriched extract of paeoniflorin on cholesterol levels, hemodynamics, and oxidative stress in a hyperlipidemic rat model. MATERIAL AND METHODS Male Sprague-Dawley rats were fed high-cholesterol diets and treated with three different doses of paeoniflorin for 12 weeks. The effects of paeoniflorin treatment were assessed on cholesterol levels, cholesterol metabolism, red blood cell vascular flow using hemorheology, antioxidant enzymes, and expression of the rate-limiting enzyme in the mevalonate pathway, 3-hydroxy-3-methylglutharyl-coenzyme A reductase (HMG-CoAR)...

BACKGROUND Renal cell carcinoma (RCC) is among the most common malignant cancers of males worldwide. For advanced RCC patients, there still is no effective therapy. Immune checkpoint blockade therapies have shown benefits for many cancers, but previous clinical trials of immune checkpoint blockade therapies in RCC patients achieved only modest results. MATERIAL AND METHODS We explored the effects of combining chemotherapy with immune checkpoint blockade therapy in RCC xenograft mouse models. We also studied the potential mechanisms by which chemotherapy might enhance the efficacy of immune checkpoint blockade therapy, both in vitro and in vivo...
