Advanced breast cancer in a relatively young man with severe obesity and type 2 diabetes mellitus

Orbital Metastases of Breast Cancer in Males

We report a case of orbital metastasis of infiltrative breast carcinoma in a 65-year-old man. The patient was diagnosed with stage four breast cancer one year before, for which a mastectomy was performed. He refused postoperative radiotherapy and chemotherapy at that time. He had a history of lung, liver, and mediastinal metastases. At admission, he presented with blurred vision, diplopia, ocular pain, and mild swelling of the upper lid of the left eye (LE). Computed tomography (CT) of the brain and orbit revealed a front-ethmoidal tissue mass with left orbital and frontal intracranial extension. Ophthalmologic examination revealed exophthalmos on the LE with a downward and outward deviation of the eyeball, proptosis, and intraocular pressure (IOP) of 40 mmHg. The patient's treatment started with topical maximal anti-glaucomatous drops and radiotherapy sessions. After three weeks of follow-up, there was a gradual improvement of local symptoms and signs and a normal IOP.

Anti-Obesity Effect of DKB-117 through the Inhibition of Pancreatic Lipase and α-Amylase Activity

This study sought to evaluate the effects of Phaseolus multiflorus var. albus Bailey extract (PM extract) and Pleurotus eryngii var. ferulae extract (PF extract) on the inhibition of digestive enzymes and to confirm the anti-obesity effect of DKB-117 (a mixture of PM extract and PF extract) in digestive enzyme inhibition in a mouse model of obesity induced by a high-fat diet. In in vitro studies, PM extract and PF extract have increased dose-dependent inhibitory activity on α-amylase (Inhibitory concentration (IC₅₀ value: 6.13 mg/mL)) and pancreatic lipase (IC₅₀ value; 1.68 mg/mL), respectively. High-fat diet-induced obese mice were orally administered DKB-117 extracts at concentrations of 100, 200, and 300 mg/kg/day, while a positive control group was given orlistat (pancreatic lipase inhibitor) and Garcinia cambogia (inhibiting the enzymes needed to synthesize carbohydrates into fat) at concentrations of 40 and 200 mg/kg/day, respectively, for eight weeks. As a result, body weight, fat mass (total fat mass, abdominal fat, and subcutaneous fat) detected with microcomputed tomography, fat mass (abdominal fat and inguinal fat) after an autopsy, and liver triglyceride levels were decreased significantly in the DKB-117 (300 mg/kg/day) group compared to those in the HFD control group. Additionally, we obtained results indicating that the presence of carbohydrates was found more in the DKB-117-300 (300 mg/kg/day) group than in the HFD control group. These data clearly show that DKB-117 extracts are expected to have an anti-obesity effect through a complex mechanism that promotes carbohydrate release through the inhibition of carbohydrate-degrading enzymes while blocking lipid absorption through lipase inhibition.

High glucose contributes to the proliferation and migration of non-small cell lung cancer cells via GAS5-TRIB3 axis

Despite the growing number of studies exhibited an association of diabetes mellitus (DM) and lung cancer progression, the concrete mechanism of DM aggravating lung cancer has not been elucidated. This study was to investigate whether and how high glucose (HG) contribute to the proliferation and migration of non-small cell lung cancer (NSCLC) cells in vitro. In the present study, we confirmed that HG promoted the proliferation and migration of NSCLC cells, and also induced an anti-apoptosis effect on NSCLC cells. Moreover, HG inhibited the expression of GAS5 in NSCLC cells but elevated the protein level of TRIB3. GAS5 overexpression promoted the degradation of TRIB3 protein by ubiquitination and inhibited the HG induced-proliferation, anti-apoptosis and migration of NSCLC cells. Importantly, TRIB3 overexpression reversed the effects of GAS5 on the HG-treated NSCLC cells. Taken together, down-regulated GAS5 by HG significantly enhanced the proliferation, anti-apoptosis and migration in NSCLC cells through TRIB3, thus promoting the carcinogenesis of NSCLC.

Herbal Medicine for the Treatment of Obesity: An Overview of Scientific Evidence from 2007 to 2017

Obesity is a very common global health problem, and it is known to be linked to cardiovascular and cerebrovascular diseases. Western medical treatments for obesity have many drawbacks, including effects on monoamine neurotransmitters and the potential for drug abuse and dependency. The safety of these medications requires improvement. Herbal medicine has been used for treatment of disease for more than 2000 years, and it has proven efficacy. Many studies have confirmed that herbal medicine is effective in the treatment of obesity, but the mechanisms are not clear. This article will discuss the possible effects and mechanisms of herbal medicine treatments for obesity that have been reported in the past decade.
