There is a contradictory between patients' privacy on his condition and the public' civil of knowing facts in the course of preventing and treating SARS.The contradictory should be argued in favor of ethics and be supported by social psychology.

Now the treatment of lymphoma mainly uses combined chemotherapy and radiotherapy.Es- pecially hemopoietic stem cell transplantation is effective in the treatment to the patients with refractory and later stage.During the recent years the domestic and foreign scholars have obtained the encouraging results with arsenic trioxide to treat lymphoma.This article has reviewed the experimental study and the clinical re- search progress about arsenic trioxide in application to lymphoma cells.

Due to the latent and highly invasive characteristics of liver carcinoma,a majority of patients are frequently not diagnosed until moderate or advanced stage in the disease process,and usually complicate with cirrhosis.Only 15％ -30％ of the patients are eligible for radical resection.The overall survival time is about 3-4 months.Therefore,on the basis of early diagnosis and treatment of liver carcinoma,how to improve the treatment effect of the moderate and advanced liver carcinoma,ameliorate the quality of life and prolong the survival time,becomes the focuses and difficulties both at home and abroad.

Objective The purpose of this study was to investigate the preventive effect of flurbiprofen axetil or small-dose ketamine for remifentanil-induced postoperative hyperalgesia. Methods 120 anesthetized patients with ASA ⅠorⅡwere randomly divided into three groups. Group A (40 cases) was given 0.5 mg/kg of ketamine by intravenous injection,and 5μg/(kg.min) vein to maintain,group B (40 cases) was given 100 mg of preoperative flurbiprofen axetil by intravenous injection and group C (40 cases) had no flurbiprofen axetil or ketamine which was served as controls. After the treatment, all groups were given continuous intravenous tramadol controlled analgesia (PCIA) . Results After 1 h, 2 h, 4 h and 8 h, the visual analog scale (VAS) of group C was significantly higher than that of group A and group B ( <0.05);after 24 h, there was no statistically significant difference among the three groups in VAS scores ( > 0.05) . The number of fentanyl analgesia were 25 cases and postoperative 24 h PCIA self-control were (8.6 ±4.2) times, which were more than 7 cases and (3.3 ±2.8) times of group A, and 6 cases and (3.2 ± 2.2) times of group B ( <0.05) . Conclusion The preoperative administration of flurbiprofen axetil or intraoperative continuously administered ketamine is able to prevent the occurrence of remifentanil-induced postoperative hyperalgesia, and it will not affect the patient regained consciousness. The method is safe and reliable,so it is worth promoting and popularizing.

Micrometastasis is small metastasis at the cellular and molecular level. Early detection of micrometasis through tumor markers can improve the accuracy of TNM staging, prognosis and subsequently treatment for lung cancer patients. Currently, a number of markers with good specificity and sensitivity have been found, including CK19 mRNA, Lunx mRNA, MUC1 mRNA and GPRP mRNA. These markers can be detected using methods such as RT-PCR, immunohistochemistry and western blot.

Silk fiber,as a kind of natural polymer,has been used as surgical sutures in clinic for years.Silk fiber is composed of a filament core protein,termed fibroin and a glue-like coating called sericin proteins.Due to its unique mechanical properties,good biocompatibility and slow degradability,silk fiber has been put in variety of applications as a new kind of biomedical scaffolds in recent years.With the development of the processing technique,silk fiber can be processed through the new versatile processing method to form various forms of scaffolds and its surface could be modified for different purposes.Further more,it could be tailored through genetic recombination to form the silk fibroin-like polymers which has a promising potential in medical applications.

Ovjective To observe the surgically excised specimens from eyes with hemorrhagic agerelated macular degeneration (AMD).Methods Thirty-six surgically excised specimens were captured from 36 patients with hemorrhagic AMD,26 specimens were diagnosed as occult choroidal neovascular membrane (CNVM),10 specimens were diagnosed as polypoidal choroidal vasculopathy (PCV).All specimens were routinely processed by hematoxylin and eosin,periodic acid-Schiff's stain and Masson stainings.At the maximum horizontal and vertical slice of the specimens,the category and amount of the cells in the specimen were recorded,as well as the relationship between the specimens and the surrounding tissue.Results The 36 specimens are categorized as neovascular membrane dominant (19/36),collagen fiber dominant (6/36),blood clot dominant (8/36) and degenerated thickened Bruch's membrane dominant (3/36).Eighteen occult CNVM specimens and 1 PCV specimen are categorized as neovascular membrane dominant; all 6 collagen fiber dominant specimens are occult CNVM; 1 occult CNVM and 7 PCV specimens are categorized as blood clot dominant; and 1 occult CNVM and 2 PCV specimens are categorized as degenerated thickened Bruch's membrane dominant.The occult CNVM categorized as neovascular membrane dominant present as small blood vessel with single endothelium cell attached; the PCV specimen categorized as neovascular dominant presents as big blood vessel with thick vessel wall under the Bruch's membrane,retinal pigment epithelium and choroidal melanocyte are both observed in the PCV specimens.Conclusion The components of the specimens captured from eyes with hemorrhagic AMD are diversified.

The relative content of DNA-RNA and the nuclear area/nucleolar area ratio of the hyperplastic tissue,glottic polypus,dysplastic tissue of grade I to I laryngeal squamous cell carcinoma were measured in 33 cases with image analysis technique.It was found that the changes of DNA-RNA content and the ratio of nuclear/nucleolar area were parallel to those of the severity of the carcinoma,and RNA was markedly increased in grade 11 and I dysplastic tissue.On the basis of the current grading of laryngeal pathology,the combined determination of DNA-RNA can provide more sensitive indicators to the stages of malignant degeneration of the laryngeal squamous cell carcinoma.

Objective To investigate of the expression of vascular endothelial growth factor receptor 3 (VEGFR-3) and its relationship with the prognosis of esophageal carcinoma. Methods VEGFR-3 in 156 cases of esophageal carcinoma tissues was detected by immunohistochemistry. The follow-up data for 3 years in 47 cases were analyzed. Results The VEGFR-3 expression in esophageal carcinoma tissues with lymph node metastasis was higher than that in those without lymph node metastasis. VEGFR-3 expression was associated with the clinicopathological stages. Analysis of the follow-up data also showed that there was a statistically positive correlation between VEGFR-3 expression and lymph node metastasis in primary tumors (P
