According to the medical history,imaging and pathological diagnosis,the advanced gastric cancer patients able to tolerate radiotherapy can be divided into the following three groups:(1) unresectable locally advanced or locally recurrent disease;(2) metastatic disease at primary diagnosis with stage Ⅳ;(3) patients experiencing severe tumor-related clinical symptoms.The role of palliative radiotherapy in patients with advanced gastric cancer would be discussed by reviewing 33 articles (8 in last five years,13 in ten years).

ObjectiveTo investigate the value of CEUS in differential diagnosis of benign and malignant thyroid solid lesions.MethodsTotally 45 patients with thyroid solid lesions underwent CEUS examination.The enhancement mode and blood perfusion characteristics of malignant and benign lesions were analyzed,and the results were compared with pathology.ResultsCEUS diagnosed 31 benign lesions and 14 malignant masses.The diagnostic accordance rate of CEUS was 93.75％ (30/32) and 92.31％ (12/13) for benign and malignant lesions respectively.In 31 benign lesions,27 (27/31,87.10 ％) showed entire homogeneous enhancement,4 (4/31,12.90％) presented inhomogeneous enhancement.In 14 malignant masses,1 (1/14,7.14 ％) showed homogeneous hypoechoic enhancement,12 (12/14,85.71％) presented inhomogeneous hyperechoic enhancement and 1 (1/14,7.14％) presented non-enhancement.ConclusionCombined with two-dimensional grey scale ultrasound and CDFI,CEUS enables dynamic observation of the microvascular perfusion of thyroid lesions,therefore helps to differentiate benign and malignant thyroid lesions.

Sphingosine-1-phosphate (S1P) is a lysophospholipid signaling molecule that regulates important biological functions in both intracellular and extracellular compartments. It interacts with five G protein-coupled receptors subtypes (S1PR(1-5)) to generate multiple downstream signaling. Activation of S1PR1 has been validated to be involved in the process of immune modulation. Fingolimod (FTY720), the novel S1PR1 agonist, has been approved for the treatment of multiple sclerosis in clinical trials. The study towards discovery of selective S1PR1 agonists has become hot spot for immunological diseases. This article summarized the research progress of S1PR1 agonists, emphasizing their structure types, structure-activity relationship and direction of development.

Objective To investigate the changes of antibiotic resistance and its correlations with antibiotics use density (AUD) in intensive care unit (ICU) after implementation of antimicrobial stewardship. Methods Data on AUDs and synchronous antibiotic resistance in ICU of the Affiliated Hospital of Taishan Medical University during 2010 and 2014 were retrospectively reviewed.Autoregressive integrated moving average ( ARIMA) model was used to identify the correlation between AUDs and antibiotic resistance.Results The total AUD which stood at 163.46 DDDs· 100 person-1 · d-1 in the year 2010 decreased to 68.20 DDDs · 100 person-1 · d-1 in 2014, and the most significant decreases were found in quinolones, imidazole, carbapenems, aminoglycosides, other beta lactam and macrolides. Synchronously, a wide range of improvements in antibiotic resistance of major pathogens were also observed from 2010 to 2014, and the improvements were positively correlated with the decrease of AUDs.However, antibiotic resistance in 2014 was not significantly improved compared with that in 2013. The rate of ciprofloxacin resistance in Pseudomonas aeruginosa and the resistant rates of amikacin, imipenem, and meropenem in Acinetobacter baumannii even increased in 2014.Conclusions With the implementation of antimicrobial stewardship, antibiotic consumption in ICU was decreasing, and antibiotic resistance rate in major pathogenic bacteria was decreasing.But the rebound in antibiotic resistance in some types of bacteria was also observed and should be put on enough caution.

Objective:To study the eExecutive fFunctions Characteristics of Cchildren with Aattention dDeficit hHyperactivity Ddisorder in Cclock Ddrawing Ttest. Methods: 60 ADHD children and 60 normal children awere tested by CDT. Then analyze the data to detect the difference of Executive Functions of two growps. Results:ADHD group geot significant lower scores than control group on both time total score (data) and clock face structure score. (3.23?1.40/4.15?0.78,11.2?1.48/11.90?0.76,t=7.742、5.073,P0.05). Conclusions: the lower score in CDT showed that ADHD child have some weaknesses in planning , in attention regulating and in working memory. The core of these weaknesses is failing of execute function.

Pesticide played an important role in agriculture. With the increase of pesticides in recent years,they have easily gone into the aquatic environment through some ways such as rain or surface water. The residual pesticide in the water may destroy the aquatic ecosystems,do harm to the aquatic organisms and human health,now more and more attention has been paid to the situation of the pesticide pollution in the aquatic environment. This present paper introduced the type of common pesticide residues in the water in China, it also described the pesticide pollution situation in rivers,groundwater,marine and other water as well as the potential impact of pesticide on the aquatic organisms and human health,in order to provide a basis for China to carry out relative research.

Chemoradiotherapy is an important part in the adjuvant regimen for locally advanced gastric cancer after radical resection. Adjuvant chemoradiotherapy has demonstrated a clear local control and survival advantage for locally advanced patients with less than D2 lymph node dissection. Thus, chemoradiotherapy is recommended as standard of care in the postoperative setting. However, the role of radiotherapy for patients with more extensive D2 lymph node dissections remains controversial. Three phase III random-ized clinical trials in Asia show that adjuvant chemoradiotherapy after D2 dissection is safe and feasible and may benefit certain groups of patients. The benefit of radiotherapy in the case of more extensive surgery still warrants well-designed, fully powered randomized controlled clinical trials for verification. More studies are needed to focus on the identification of patient subgroups that are at high risk for locoregional failure and may benefit from adjuvant chemoradiotherapy. Further optimization of target volume in the radiother-apy and exploration of new modalities of radiation techniques are also necessary.

This paper concluded the health status of the population migrated from agriculture areas as well as the existing problems of health rights and interests in the process of new urbanization, and proposed the following suggestions:it must strengthen the government responsibility, adhere topeople-oriented, and firm social ethics construction. It also should plan health resource allocation, adjust the medical security policy, improve service quality according to the characteristics of population migrated from agriculture areas, and build up a multi-level and joint health service system.

Objective: To observe the clinical efficacy of puncturing Renying (ST 9) in the treatment of poststroke dysphagia. Methods: Sixty cases of poststroke dysphagia were randomized into two groups, a control group in which 30 cases were given rehabilitation training, and a treatment group in which 30 cases were treated by puncturing Renying (ST 9) and rehabilitation training, with a course of four weeks. Results: The total effective rate for dysphagia was higher in the treatment group than in the control group (P<0.05). Conclusion: Puncturing Renying (ST 9) is quite effective for poststroke dysphagia.
