Objective To explore the variation about the application of fast-track surgery and laparoscopy in treatment for colorectal cancer in recent years.To investigate the probability of combining protocols of the two for treatment for colorectal cancer.Methods The clinical and basic literatures of related researches about colorectal treatment of laparoscopy and fast-track surgery were collected and reviewed.Results Compared with the traditional treatment modalities,both of fast-track surgery and laparoscopy used for the treatment of colorectal cancer have better clinical effects.Conclusions Fast-track surgery and laparoscopic techniques used for the treatment of colorectal cancer are feasible,but the combination of the two should be confirmed by further randomized controlled trials.

Fetal intrauterine growth restriction is one of the common diseases in the perinatal period,which not only increases the child morbidity and mortality in the perinatal period,affecting the long-term development of the nervous system,and can make the risk of adult obesity,hypertension,type Ⅱ diabetes increased significantly.A number of studies suggest that the down-regulation of A amino acid transporter expression is closely associated with intrauterine growth restriction.The down-regulation of A amino acid transporter expression may be an important cause of intrauterine growth restriction.

Although the treatment of aneurysmal subarachnoid hemorrhage (SAH) has made considerable progress in recent years,its mortality and disability have not been effectively controlled.Ischemic brain injury after SAH is considered to be an important reason for the poor prognosis of patients; however,its mechanism is still not fully understood.Studies have shown that the cerebral microcirculation disturbance after SAH is closely associated with ischemic brain injury.This article reviews the advances in research on cerebral microcirculation disturbance and ischemic brain injury after SAH.

Objective To investigate the effect of ketamine on learning and memory function of adult rats after injection of ketamine at early development stage. Methods Twelve rats born in a week were randomly divided into ketamine anesthesia group(Ket group)and normal saline control group(Ns group).Rats in Ket group were intraperitoneally injected with 50 mg/kg ketamine,and those in Ns group were administrated with same amount of normal saline.After eight weeks,Morris water maze test was adopted to explore the latency in place navigation and spatial probe ability.The sections of hippocampus were obtained,and immunohistochemical staining was employed to detect the expression of Bax and Bcl-2.Results In Morris water maze test,the latency in place navigation of Ket group Was significantly longer than that of Ns group(P<0.05),and the spatial probe ability significantly decreased(P<0.05).It Was revealed by immunohistochemical staining that the expression of Bax in Ket group was significantly higher than that in Ns group,while there was no significant difference in the expression of Bcl-2 between these two groups. Conclusion Application of ketamine in neonatal rats may result in learning and memory impairment in adulthood,and the underlying mechanism may correlate to the apoptosis of neuron in hippocampus region.

Objective To study the main causes of hearing disability in Beijing residents. Methods The second national sample survey on disability of China was carried out in Beijing on April 1,2006. Muhiphase, stratified, proportional and cluster samplings were adopted to investigate 74 795 residents in Beijing, including 36 753 males and 38 042 females. 55 773 were urban residents while 19 022 from rural areas. The method of descriptive study was used to analyze the data of hearing disabitity in Beijing. Results Top five causes of hearing disability (including multiple disabilities) in Beijing were presbycusis, unknown, systematic diseases, noise induced, and odds media. The prevalence was 1.10%, 0.30%, 0.30%, 0.20% and 0.17%, respectively. Heredity, unknown and others were the main causes of children under 0～14 years. Unknown, ototoxicity, and otitis media were the main causes of people aged 15 ～59 years. Presbycusis, systematic diseases, noise induced and unknown were main causes of people aged 60 years and older. Presbycusis was the top cause of hearing disability for male and female residents as well as people live in urban and rural areas in Beijing. Conclusion Presbyeusis, unknown, systematic diseases, noise induced, and otitis media were main causes of hearing disability (including multiple disabilities) in Beijing.

Gene therapy has emerged as an efficient modality to treat human diseases.This method is based on the transfer of genetic material to tissues to induce a curative effect.Gene therapy vectors are molecular constructs used to facilitate the penetration of genomic sequences inside the cells.Viral vectots have however several limitations when administered directly to the patient.They may cause significant toxicity by activating innate immunity or by eliciting an adaptive immune response against viral proteins.In addition,targeting the vector to the desired site is an issue when given systemically.The use of cells as vehicles for gene therapy vectors has many advantages.The combination of cell-viro-gene therapy has been thought as a new and promising strategy for therapy of cancer.The targeting vector to cancer stem cells will become a new direction in the field of gene therapy.In this article,we will introduce progressions,limitations and future directions of gene therapy of liver cancer.
