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.

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

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.

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 To approach the clinical distribution and drug resistance in nosocomial infections with Acinetobacter baumannii(ABA) to provide the scientific evidence for clinical diagnosis and treatment.METHODS Referring to National Rules of Operation in Clinical Laboratory,215 strains of ABA were isolated.Microscan auto-4 was used to identify strains.And the antibiotic susceptibility test was performed by K-B method.The test results were judged according to CLSI 2007.RESULTS The top four of isolated rates were the intensive care unit(23.3%),department of neurology(17.7%),department respiratory medicine(15.8%) and department of tumor(14.4%).The detection rate of ABA from specimen from respiratory tract was the highest,arriving at 72.6%.The antibiotic susceptibility test showed ABA had been resistant to commonly used antibiotics.The resistance rates to imipenem and meropenem were 22.3% and 23.7%,respectively.The isolated rate of pan-resistant stains was 7.4%.CONCLUSIONS Hospitals should think highly of monitoring and controlling of drug resistance in ABA and prevent nosocomial infections with multidrug resistant strains.

Objective To explore the influence of different anesthetics on emergence agitation (EA) after general anesthesia. Methods 134 EA patients after general anesthesia were randomly divided into three groups. Group A (n=42), Group B (n=45) and Group C (n=47) was given intravenously parecoxib 40 mg, butorphanol 20μg/kg and tramadol 1 mg/kg, respectively. The improvement of agitation, VAS score and Ramsay score were compared and analyzed among the groups. Results After treatment, the degree of EA in Group A, Group B was significantly lower than that in Group C ( <0.05) . VAS score in all the cases was reduced, and Ramsay score was increased compared with that before treatment ( <0.05) . VAS score in Group C was significantly higher than that in Group A, Group B (<0.05) . Ramsay score in Group B was significantly higher than that in Group A, Group C (<0.05) . After treatment, awaking time and postanesthesia care unit (PACU) stay in Group B was significantly higher than that in Group A, Group C (<0.05) .Conclusions Parecoxib is safe and effective for EA after general anesthesia, it can effectively improve the degree of EA, increase postoperative sedative effect, and shorten PACU stay.

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 evaluate the analgesic effect of botulinum toxin type A (BTX-A) in osteoarthritis model and the changes of Nav1.8 protein expression in spinal ganglia changes.Method:Animal model of knee osteoarthritis (KOA) was established by intra-articular injection of 4％ papain solution 0.3ml into SD rat right knee.After the formation of arthritis,they were randomly divided into two groups at the 2nd day:BTX-A group (n=10):intra-articular injection of 5μl BTX-A 0.1IU;WFI group (n=10):intra-articular injection of 5μl water.No papain or BXT-A was given to the sham group (n=10).At the 1st,3rd,5th day after injection,we tested the pain behavior,thermal pain threshold,and sodium channel 1.8 (Nav1.8) protein expression in spinal ganglion by using immunohistochemistry.Result:Analysis of spontaneous pain behavior showed abnormal gait caused by rat osteoarthritis.Comparing with the WFI group,abnormal gait caused by osteoarthritis improved significantly in BTX-A group.At day 5 it improved more significantly than day 1 and day 3.Thermal pain threshold of BTX-A group increased more than that of WFI group (P＜0.05) at any time point.Abnormal high Nav1.8 protein in model rats decreased in spinal ganglia for BTX-A group.Conclusion:The intra-articular injection of BTX-A may play the analgesic effect in the model of KOA by down-regulating of the expression of Nav1.8 protein in spinal ganglia and reduction in the central sensitization to pain stimulation.
