This paper describes the value of positron emission tomography(PET) in diagnosis and staging of lung cancer. Current status and prospect of positron emission tomography in mainland of China were briefly discussed: PET examination cost has not been covered by national health care system at present. Numbers of PET should be increased within limits and its development should keep balance with economic and social development level. It is necessary to have more nuclear medicine physicians training and cooperation between PET physicians and clinical referring physicians.

Objective To study the levels of serum acute-phase proteins,interleukin-6(IL-6) and tumor necrosis factor-?(TNF-?) in different stages of diabetic nephropathy in type 2 diabetes mellitus(T2DM) and to explore the clinical significance.Methods One hundred and five patients with T2DM diagnosed by WHO(1999) criteria were divided into three subgroups according to their urinary albumin excretion rate(UAER): 34 cases normal UAER group(NA group),31 cases microalbuminuria group(MA group) and 30 cases clinical proteinuria group(CA group).Thirty-three healthy individuals were selected as controls(NC group).The levels of acute-phase proteins including C reactive protein(CRP),?_1-acid glycoprotein(?_1-AAG),ceruloplasmin(CER) and haptoglobin(THP) were measured with immunoscattering assay,The levels of IL-6 and TNF-? were detected with electrochemiluminescence immunoassay.Results The levels of serum acute-phase proteins,IL-6,TNF-? were significantly higher in patients with T2DM than those in NC group(all P

Objective: To analyze the prevalence and changing trend of overweight and obesity among high school seniors in Beijing from 2009 to 2018, and to provide scientific basis for health and education departments to work out effective measures to prevent and control overweight and obesity among adolescents. Methods: The physical examination data of 700 588 high school seniors in Beijing from 2009 to 2018 were selected to describe the distribution characteristics of the detection rate of overweight and obesity, and to analyze whether there are differences in the prevalence of overweight and obesity among different genders and regions. Results: From 2009 to 2018, the prevalence rate of total overweight and obesity of high school seniors in Beijing showed an increasing trend by year ( χ 2=3.58, P <0.01). After 2016, the rising trend was more stable, and it declined for the first time in 2018. The prevalence of overweight ( χ 2=6 681.34, P <0.01) and obesity ( χ 2=15 663.08, P <0.01) were higher in male than in female. The prevalence of overweight and obesity in urban students was higher than that in suburban students (29.55%,27.95%; χ 2=211.43, P < 0.01 ), the prevalence of obesity in urban students was higher than that in suburban students from 2009 to 2013, and the prevalence of obesity in suburban students was higher than that in urban students from 2014 to 2018. The districts and counties with the highest detection rates of overweight and obesity are Shijingshan District (overweight: 19.06%, obesity: 13.99%), and the districts and counties with the lowest detection rates of overweight and obesity are Yanqing District (overweight: 13.48%, obesity: 7.18%). Conclusion From 2009 to 2018, the prevalence of overweight and obesity among high school seniors in Beijing has been increasing by year, and tends to be stable after 2016. Significant upward trend in obesity prevalence in suburban areas of Beijing has been observed.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.
