Objective:To approach the change of five serum markers such as CA15-3、CA125、CEA、CYFRA21-1 and TPS with breast cancer between pre-and post-neoadjuvant chemotherapy,to screen the better treatment effectiveness evaluation markers.Methods:The serum markers such as CA15-3、CA125、CEA、CYFRA21-1 and TPS of 48 cases with breast cancer were detected by enzyme linked immunosorbent assay respectively pre-and post-neoadjuvant chemotherapy.Results:In effective group,CA15-3、CYFRA21-1 and CEA were significantly decreased(P0.05).Through Logistic multiple factor regression analysis,CA15-3?CYFRA21-1and CEA were the better markers of among the five markers to evaluate the neoadjuvant chemotherapy efficacy of breast cancer,and evaluate role from strong to poor by turns.Conclusion:CA15-3 was the best marker of five serum markers to evaluate the neoadjuvant chemotherapy efficacy of breast cancer.

The results suggest that the root cause of formation of peritoneal adhesions is cong-cllation. produced by exudation of fibrin. Extensive adhesions are associated with multi-factors.The principal measures to prevent peritoneal adhesions are removing of exudate and foreign bodies during abdominal operations.Granulation composed mainly of spin die-shaped fibroblasts and capillaries forms by 72 hours, indicating that congelation caused by multi-factors can result in peritoneal adhesions at the initial stage.The effccient precautions against adhesions within three days need further research.There were no normal mesothelial cells, which have fibrinolytic activity, to be found in the study.The reason may be that plasminogen activating factor in the blood vessels beneath mesothelium is inhibited by ischemia,injury,infection,foreign bodies and hemorrhage. This is worth notice in the prevention and treatment.

OBJECTIVE To explore the correlative fators of nosocomial infections of preterm infants and decrease the infections rate of preterm infants.METHODS A retrospective analysis of nosocomial infection was made among preterm infants in our hospital from Jan 1998 to Dec 2005.RESULTS The incidence rate of nosocomial infections of preterm infants was 12.28%.The most infection site was respiratory tract.Small gestational age,low birth weight and birth asphyxia were the risk factors of nosocomial infections.CONCLUSIONS Intensive care of preterm infants and rational use of antibiotics are effective methods to decrease the rate of nosocomial infections.

The emergence of drug resistance mutations in human immunodeficiency virus (HIV) genome is the major reason for antiviral treatments failure.To investigate the drug-resistance viral quasispecies in HIV-infected individuals and to find out the new drug resistance mutations have significant effects on directing effective clinical treatment and developing novel antiviral drugs.HIV drug resistance tests mainly include genotypic drug susceptibility assay and phenotypic drug susceptibility assay.We reviewed in this article some novel development in the field.

Objective To establish a method for the determination of arsenic in urine by microwave digestion-oscillopolarographic method. Methods The urine samples were treated by microwave digestion. After being reduced to As3+,total arsenic in the samples was determined by oscillopolarographic method in the system of H2SO4-KBr-Se4+. The experiment conditions were optimized. Results The linear range of the method was 0-50 ?g/L(r=0.999 8),the limit of detection was 0.67 ?g/L,the relative standard deviation was 1.44%,and the rates of recovery were 95.0% -103.0%. Conclusion The method is simple,rapid,accurate and applicable to the determination of arsenic in human urine,which presents an advantage of low losing of arsenic in the treatment and determination.

The diseases of esophagus and stomach possess highest morbidity in China. For decades the interventional radiology has effectively solved a lot of clinical puzzles upon the lesions of esophagus and esophagogastric junction. Rapid development and extensive application offen induce the exaggeration of indication and improper choice of the proceduce, resulting in clinical disposal for various complications. Scientific attitude should be taken on the utilization of interventional method: possessing rich imaging and clinical knowledge; understanding the property of various interventional instruments; strictly grasping indications of arterial infusion chemotherapy, balloon catheter dilation and stent placement; perfectly mastering the operation technology; well controlling complications.

Emodin is the main effective monomer of Rhubarb, which has a variety of pharmacological actions and valuable clinical applications.Recently, there are many reports about molecular mechanisms of emodin pharmacological actions,and they givehighly attention on the dephlogisticating and antineoplastic effects. These effects are achieved through affecting the concentration and transportation of ions, resisting of oxidation and free radical, and affecting the secretion of inflammatory factor and the enzyme activity and apoptosis and so on. This article summarizes the reports and hopes to provide theoretical basis for the practical application.

After many targeted drugs have entered into the treatment guideline or all stage clinical trial of non-small-cell lung cancer (NSCLC), many researchers undertake deep investigation on the role of molecular gene marker in targeted therapy of NSCLC. It is a good outset that mutation detection of epidermal growth factor receptor (EGFR) gene direct the selection of EFGR tyrosine kinase inhibitors (EGFR-TKI). To choose individualized therapy regimens according to molecular gene marker will be the important research direction, but also be the critical measure to improve the management level of NSCLC and prolong patient"s survival. Accompanied with deep investigation of targeted therapy, there will be more molecular gene markers to direct the formulation of individualized therapy regimens.

Many clinical studies have demonstrated that raised morning blood pressure surge is closely related to path‐ogenesis and prognosis of cardiovascular diseases ,but there is still no unified understanding for its prevention until now ,and raised morning blood pressure surge phenomenon is not effectively controlled in most patients .The pres‐ent article made a brief review on raised morning blood pressure surge .

Objective To observe the clinical efficacy of acupuncture plus rehabilitation training in improving post-stroke dysphagia. Method A total of 60 patients with post-stroke dysphagia were randomized into a treatment group and a control group, 30 cases in each group. The two groups were intervened by basic treatment of internal medicine and swallowing rehabilitation training, and the treatment group was additionally given acupuncture treatment. The Standardized Swallowing Assessment (SSA), water swallowing test and Swallowing Quality of Life Questionnaire (SWAL-QOL) were evaluated in the two groups before and after the treatment. Result After the treatment, the SSA scores in the two groups were significantly decreased compared to those before the treatment (P<0.01), and the SWAL-QOL scores were significantly increased compared to those before the treatment (P<0.01); the SSA score in the treatment group was significantly lower than that in the control group (P<0.01), and the SWAL-QOL score was significantly higher than that in the control group (P<0.05). The water swallowing test classification after the treatment was significantly superior to that before the treatment in the treatment group (P<0.01), and there was a significant difference compared to that in the control group (P<0.05). Conclusion Acupuncture plus rehabilitation training can obviously improve the swallowing function of patients with post-stroke dysphagia, and the clinical efficacy was superior to single rehabilitation training.
