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).

Objective To evaluate the clinical application of ultrasound-guided Mammotome system in the treatment of breast lesions.Methods A total of 1081 patients with 1913 breast lesions received Mammotome minimally invasive excision,and the efficacy of treatment and follow-up results were retrospectively analyzed.Results All 1913 lesions in 1081 patients were treated with the Mammotome system.The duration of operation was 4 minutes,and the average excision times was 15 for every lesion,1894 lesions (99.01%) in 1063 patients were benign breast masses,19 lesions (0.99%) in 18 patients were breast carcinoma.Complication occurred in 39 lesions (2.04%).Conclusion Ultrasound-guided Mammotome system is one of the effective ways in the clinical diagnosis and treatment of breast lesions.

Objective To discuss the prenatal diagnosis of abnormalities of fetal limb bone.Methods We selected 18 cases which long bone of fetus less than 2SD of average volume of gestational weeks or long bone changed into angle or other fetus's abnormalities by first B-mode ultrasonic. All above cases was delivered at Capital Medical University of Obstetric and Gynecological Hospital during Jan. 2006 to Dec. 2009. We B-mode ultrasonic was used to measure fetus's biparietal diameter (BPD) ,femur length (FL) ,abdominal circumference(AC) ,head circumference(HC) ,humerus length (HL) ,amniotic fluid index (AFI) and structures of organ and calculated FL/AC, growth speed of long bone. The standard of achondroplasia is that FL and HL are less than 4SD of average of gestational weeks or FL/AC less than 0. 16. The standard of Osteogenesis Imperfecta is fetal long bone of fetus shows short and thick, curves into angle, fracture in uterus by X-ray, or skull shows thin or sink by X-ray. Results (1) By B-mode ultrasonic and X-ray exam of all 18 cases: 7 cases shows that HC ＞2SD, 10 cases shows too much amniotic fluid, 12 cases shows AFI ＞ 18.0, 9 cases shows abnormalities of narrow cavitas thoracis, disordered vertebral column, or unusual architecture of heart. For cases 1 to 14 are achondroplasia, among which,11 cases are FL＜4SD and HL＜4SD, 2 cases are FL ＜3SD and HL ＜4SD, 1 case is not only FL ＜2SD and HL ＜3SD but also hydroncus all over the body of fetus. The growth velocity of long bone of fetus in all the 14 cases is more slowly than the normal rate. For all the above 14 cases, 12 cases FL/AC ＜0. 16, 1 case FL/AC =0. 19, 1 case FL/AC =0. 20. The length of femur or humerus is shorter than the normal rate and have other abnormalities the above last two cases. For case 15 and 16, they don't show any abnormalities of bone growth though one year's follow up studying. For case 17 and 18, they are osteogenesis imperfecta. (2) The result of fetal perinatal period fate and autopsy: there are 8 female and 10 male in all the 18 cases. One case is labored after 39 weeks pregnancy, and it is low birth weight infant, weight ＜3%th. All the other cases are normally birth weight infant. All the 18 cases of abnormalities of fetal limb bone are examined by chromosomes check, among which, 9 cases are amniocentesis, 7 cases are cordocentesis,2 cases are checked chromosomes by fetus cord blood, all the caryotype are normal. In the 16 autopsy cases,14 cases are achondroplasia or hypochondroplasis. It can be seen amplifying extremities, hyperplasia chondrocytes of tubiform born, karyomegaly, anachromasis, hyperplasia capillaries though microscope and grow up into cartilage irregularly. Also can be seen hyperplasia chondrocytes of epiphyses, delaying osteosis.2 cases are osteogenesis imperfecta. It can be seen broadening of metaphyses, exility of bone trabeculae. For the other two cases which the fetus is alive, we do the follow up studying to their one year old one of them is low birth weight new born, their limb and height are all normal. Conclusions To diagnose fetal Achondroplasia, it is not only based on the significantly shorter of femur or humerus length but also based on the dynamics observing the long bone growth velocity and calculating FL/AC. For osteogenesis imperfecta fetus, it should be diagnosed by fractures in uterus though X-ray.

The role of bacterial biofilms in the chronic diseases has been recognized more and more. The experts in the centers for disease control and prevention of the United States estimate that 65% of human bacterial infection is involved with the biofilms. In the recent study. it has been proved that there is a high correlation between the bacterial biofilm and the pathogenesis and prognosis of chronic rhinosinusitis(CRS). In order to elucidate the role of bacteria films in the pathogenesis of CRS, we reviewed various method of testing the bacterial biofilms in CRS, and summarized the related researches. Based on the detection researches and summaries, we conclude that bacterial biofilm can contribute to the continuance and development (diffusion and repeated) of CRS. It can lead to the continuous inflammation by influencing the immune system of the mucous membrane. While there is little research on the bacterial biofilm. Further researches will be needed for the exact mechanism of the bacterial biofilm in CRS. in order to find more effective therapeutic method and targets.

Eukaryotic elongation factor 2 kinase (eEF2K) is well known as a Ca2+/calmodulin (CaM)-dependent kinase. eEF2K catalyzes the phosphorylation of eEF2 and subsequently inactivates eEF2 by impairing its ability to bind to the ribosome, thereby negatively modulates protein synthesis. The high expression of eEF2K has been found recently in several types of malignancies. As participating in the progress of tumor, eEF2K emerges a potential target for future cancer therapy. The relationship between eEF2K and tumor, and the latest progress of eEF2K inhibitors were summarized in this article.

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.

Objective To investigate the antimicrobial properties of human amniotic homogenate supernatant (HAHS) in order to found a theoretical base for the use of human amniotic membrane in ophthalmological field. MethodsFresh human amniotic membranes were used to make HAHS and acellular amniotic membranes. Then, we observed their antimicrobial effects and antimicrobial spectrums, compared the antimicrobial capacity with 10 commonly used antibiotics in eyes, and investigated the effects of time, temperature and pH value on the antimicrobial capacity. Finally, transmission electron microscopy (TEM) was used to explore the possible targeting site of the antibiosis. ResultsHuman amnion membrane contained antimicrobial components locating in its epithelial cells. HAHS had a broad antimicrobial spectrum and was steady in nature. Its antimicrobial capacity was stronger than those of sulfasulfonamide, chloromycetin and cefuroxime sodium. TEM indicated that the antimicrobial effect were exerted through plasma membrane of microorganism. ConclusionHAHS can be an effective and convenient treatment for ocular surface infectious diseases. Traditional amnion transplantation should employ fresh human amniotic membranes containing complete epithelial lamina to reconstruct the ocular surface.

Objective To evaluate the in vivo efficacy of modified platelet(PLT) additive solution(PAS-ⅢM) with trehalose as a substitute for plasma for the storage of platelet concentrates at low temperature(10℃).Methods Rabbit platelet concentrates were collected and stored in different media and temperature conditions,plasma(22℃),70%PAS-ⅢM/30% plasma(10℃) and plasma/trehalose(-85℃).Platelets in plasma(22℃) on storage day 3,in 70%PAS-ⅢM/30% plasma(10℃) on storage day 3,7,9,and in plasma/trehalose(-85℃) thawed on day 20 were transfused to rabbit thrombocytopenia model.The in vivo recoveries and survivals of the three preserved platelets and fresh platelets were measured and evaluated after transfusion into rabit model of thrombocytopenia.Results The survival of platelets stored in 70% PAS-ⅢM/30% plasma(10℃) on day 9 was lower than that of fresh platelets(P0.05).Recovery and survival of frozen platelets were significant lower than those of the other groups(P
