In 2016, American Association of Clinical Endocrinologists(AACE) published the guidelines for obesity and defined obesity as an adiposity-based chronic disease and obesity should be managed according to the obesity-related complications (16 complications are listed). Obesity intervention should be transferred from the purpose of weight loss to the intervention of metabolic disorder and its complications. The diagnosis and intervention of obesity in this guideline is sub- classified focus on the gender, region, and combined diseases, which is with more practical and scientific significances. This interpretation is expected to help the professional medical staffs to understand the new strategy in obesity therapy and to combine with the real world and clinical experience. New suggestions should put forward and improve the theories.

The rat model of obesity was induced by high fat diet and in situ hybridization was performed with oligonucleotide probes.The results showed that expressions of leptin receptor mRNA and neuropeptide Y mRNA were significantly increased, suggesting that these increments might be related to leptin resistance.

Hyperthyroidism with periodic paralysis is common in clinic,the curative effect of peroral drugs on it is not satisfactory. In order to evaluate the treatment of 131 I for periodic paralysis in patients with hyperthyroidism, fouty two patients with hyperthyroidism complicated with periodic paralysis were put on p.o. 5.0 9.0 mCi 131 I Na treatment and the remission rate of periodic paralysis was observed.The total effective rate was over 95%. It can be concluded that 131 I could be used as a routine therapy for periodic paralysis in most patients with hyperthyroidism for its safety and efficiency.

Metabolic syndrome, whose incidence is higher than that we have thought, has done great harm to people's health. This review is to introduce the recent advance in the defination,epidemiology,etiology,major risk factors,clinical diagnosis and treatment, etc . of metabolic syndrome.

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.

The new protein suppressors of cytokine signaling(SOCS) as negative regulators of signaling pathways involve in the cellular actions of many cytokines, including leptin. It regulates intracellular signal transduction cascades such as the JAK STAT pathway. SOCS is now evident of leptin resistance and has close relation with obesity. We reviewed the structure and function of SOCS 3 and the mechanism in leptin signaling pathway,providing data for the potential effect of SOCS 3 in the treatment of obesity.

Objective To investigate the effect of ketamine on learning and memory function of adult rats after injection of ketamine at early development stage. Methods Twelve rats born in a week were randomly divided into ketamine anesthesia group(Ket group)and normal saline control group(Ns group).Rats in Ket group were intraperitoneally injected with 50 mg/kg ketamine,and those in Ns group were administrated with same amount of normal saline.After eight weeks,Morris water maze test was adopted to explore the latency in place navigation and spatial probe ability.The sections of hippocampus were obtained,and immunohistochemical staining was employed to detect the expression of Bax and Bcl-2.Results In Morris water maze test,the latency in place navigation of Ket group Was significantly longer than that of Ns group(P<0.05),and the spatial probe ability significantly decreased(P<0.05).It Was revealed by immunohistochemical staining that the expression of Bax in Ket group was significantly higher than that in Ns group,while there was no significant difference in the expression of Bcl-2 between these two groups. Conclusion Application of ketamine in neonatal rats may result in learning and memory impairment in adulthood,and the underlying mechanism may correlate to the apoptosis of neuron in hippocampus region.

Objective To induce the site-directed mutation of human cardiac troponin I (cTnI) gene, express the mutant in E. coli, and to study the effects of the mutation on the prokaryotic expression of cTnI. Methods The cDNA encoding cTnI was cloned with RT-PCR from the total RNA extracted from human myocardium tissues. A pair of primers was designed and, after the mutations were induced at the second and the fourth codons, inserted into prokaryotic vector pET-28c (+) and transform the recombinant to BL21 (DE3) bacteria. After purified with Ni-NTA resin, the histidine-tagged fusion protein expressed by IPTG-induced was identified by Western blotting and the expression yield of cTnI protein was investigated. Results The expression of the recombinant carrying processed cTnI cDNA was stronger than that in control group. Conclusion cDNA encoding cTnI was successfully cloned. The recombinant with mutations can be more efficient expressed in E. coli. The cTnI protein can be purified to near homogeneity.

Objective: To explore the possible relationships of adolescent personality traits, personality deviation and parental rearing pattern. Methods: 393 students from a high school in ShanDong were tested by PACL and EMBU. Re- sults: Generally, adolescent personality traits showed different profiles while factors of EMBU varied in different levels; Antisocial personality deviation was greatly influenced by parental warmth and understanding factor, father's punishment and rigor, father's overprotection. Schizoid personality deviation was mainly influenced by parental warmth and under- standing. Passive- aggressive personality dysfunction was influenced by father's warmth and understanding. Conclusion: Adolescent personality deviation is greatly influenced by parental rearing.

Compared with CT scan results of OSAS patients and normal adults to explore the value of CT diagnosis of upper airway stricture in patients with OSAS, 35 patients with OSAS and 35 normal adults were included in the study. 22, 19, 12, 8 cases had obstruction at palate, uvula, lingua and epiglottis region respectively, the awaked CT scan results of 61 obstructive sites were compared with those of normal adults. Obvious difference was found between patients and normal adults in area, left right dimension and coronal dimension. difference was also found in thickness of lateral pharyngeal tissue of palate, uvula and lingua region and retropharyngeal tissue of palate and uvula. The normal extent was determined by unilateral 95% confidence interval in normal adult group. And 43 sites had abnormal CT scan results, the positive ratio was 72 13%. The results sugget that there are obvious differences between the patients with OSAS and normal adults, the CT scan measure can show the upper airway obstructive site of patients with OSAS.
