Obesity has been widely accepted as a metabolic disease and its occurrence is closely related to the genetics, environment, and inflammation. Up to now, body mass index is still regarded as the standard diagnostic criterion for obesity. It has not been revised for decades and could not meet the needs of clinical diagnosis and demands for specific treatment at present. In 2013, the concept of metabolic obesity was introduced at the American Diabetes Association ( ADA) annual conference, and it was further proposed that obesity should be classified according to the metabolic status and its related complications at the 2014 American Association of Clinical Endocrinologists ( AACE) annual conference. This means that scientists and clinicians have realized that the etiology of obesity may vary with different outcomes, the treatment should be focused on the metabolic regulation, not merely on weight loss. With years of clinical practice and research in obesity, we have observed and treated numerous obese patients, and we have found that obesity has a lot of phenotypes and clinical features which are related to the metabolic status. Based on our clinical findings, combined with the experience of Chinese traditional medicine, we now propose a new clinical classification and diagnosis of obesity based on individuals′ metabolic status, which, we believe, can facilitate clinicians′practice. Based on the metabolic status and skin features of obese patients, obesity is divided into metabolic healthy obesity (‘white obesity’) and metabolic unhealthy obesity. Then, the latter is further divided into three groups including high metabolic obesity (‘red obesity’ ) , low metabolic obesity (‘yellow obesity’ ) , and severe metabolic disorder with inflammation obesity (‘black obesity’ ) . If we also consider to add normal weight metabolic obesity to this classification, there should be five types of obesity to be classified as presented. We wish this proposed classification of obesity can play a valuable role in enabling clinicians to have a better understanding of obesity in relation to its metabolism, and to develop individualized treatment according to the metabolic status of the patient. As a result, we may finally achieve the desired outcomes through making appropriate diagnosis and treatments.

In recent decades, the mortality and morbidity of diabetes have increased such that it is becoming a major worldwide public health problem. Intensive blood glucose control could significantly raise the patients life and their survival quality nevertheless it develops hypoglycaemia. Repeated hypoglycemia leads to glucose conterregulate deficiencyand hamper reaching glucose target goals. Astragalus, a traditional Chinese herb used in diabetic therapy for thousands years, has also proven its glucose counterregulationeffect on preventing hypoglycemia. Here, we summarize its glycemic regulation mechanism in different extracts. It is projected that the efficacy and safety of astragalus extracts will be proven in clinical trials and animal experiments in future, and this herb extract might be known as a new class of anti-diabetic drug without hypolycemia danger.

Perioperative chemotherapy for gastric cancer has made steady progress with the application of chemotherapeutic agents and conduct of relevant clinical trials. However, palliative chemotherapy has only made marginal progress, and the median survival remains between 8-10 months. An emerging understanding of tumor biology, cellular and molecular mechanisms has revealed novel targets in gastric cancer therapy, such as trastuzumab, bevacizumab, cetuximab, etc. There are still some problems in clinical practice due to the high heterogeneity of gastric cancer including optimization of perioperative chemotherapy regimen, determination of right strategy to personalize chemotherapy or target therapy for advanced gastric cancer. In order to practically achieve individualized therapy, multicenter, prospective, randomized clinical trials according specific matters of gastric cancer should be performed in China. A deeper understanding of the biological characteristics of gastric cancer, and more translational medicine research and multi-disciplinary team collaboration should be carried out to achieve personalized medicine.

OBJECTIVE: To explore the expression and significance of programmed cell death 5 (PDCD5) and Bcelllymphoma/lewkmia-2(Bcl-2) in sinonasal squamous cell carcinoma (SNSCC). METHOD: Immunohistochemical method and Western Blot method was used to determine the expression of PDCD5 and Bcl-2 in specimen of SNSCC in thirty cases, sinonasal inverted papillomas (SNIP) in thirty-eight cases, and normal nasal mucosa in twenty cases. RESULT: (1) The expression of PDCD5 protein in SNSCC significantly decreased compared with SNIP and normal nasal mucosa. (2) The expression of Bcl-2 protein in SNSCC up-regulated obviously compared with SNIP and normal nasal mucosa. (3) Positive rate of PDCD5 protein and Bcl-2 protein in well, moderate and low differentiatied group is respectively 100.00%, 83.33%, 38.89% and 50.00%, 70.83% and 100.00%, the difference was statistically significant (P < 0.05). (4) In the follow-up cases, the survival rate of the patients with higher expression of PDCD5 protein was higher, but that with lower expression of Bcl-2 protein was higher. CONCLUSION The inactivation of PDCD5 protein and the activation of Bcl-2 protein may play an important role in the development of SNSCC, and there are a positive correlation between PDCD5 and Bcl-2 protein in SNSCC, which may be identified as a new therapeutic target.

Objective To observe the protective effects of natural antioxidant tea polyphenols(TP) on myocardial free radical metabolic disorder in mice induced by inhalation of hypobaric pure oxygen under 5500 m hypobaric condition. Method Fourty-two male Kunming mice were randomly divided into three groups(n=14 each):group A, normal control; group B, inhalation of pure oxygen(>96%) at simulated altitude of 5500 m in an animal altitude chamber;group C(TP protection group), same as group B but 100 mg/kg of TP was given orally before the exposure. The exposure time was 2 h/d,3 d/wk for a total of 8 wk, and distilled water was given to groups A and B before exposure. After experiment, the mice were decapitated on the next day and the heart was quickly removed. Malondialdehyde(MDA) concentration, superoxide dismutase(SOD) activity and nitric oxide(NO) content were measured. In addition, Cu,Zn-SOD and inducible NO synthase(iNOS) enzymatic contents in myocardial tissue were qualitatively examined by immunohistochemical assaying. Result Compared with the control, MDA concentration, SOD activity and Cu,Zn-SOD enzymatic content in group B were significantly increased(P<0.05).But in TP protection group, myocardial MDA formation was significantly decreased(P<0.01) and SOD activity and Cu,Zn-SOD expression restored to normal. On the contrary, myocardial NO generation and iNOS expression were significantly reduced after repeated inhalation of hypobaric oxygen at 5500 m.NO metabolism regained to normal after repeated administration of TP. Conclusion Natural antioxidant TP had protective effects on myocardial free radical metabolic disorder induced by inhalation of hypobaric pure oxygen under 5500 m hypobaric condition.
