Leukemia inhibitory factor(LIF) is a multifunctional cytokine.In recent years,investigations have made some advancement in the effect of LIF on central nervous system.LIF shows a high expression in various central nervous system diseases and related animal models,which shows a neuroprotective effect most time in central nervous system injuries.LIF is defined as a neurotrophic factor.It might provide a new strategy for the therapy of central nervous system diseases to undertake further studies on leukemia inhibitory factor and central nervous system diseases.

Objective The high-pressure-vapor disinfection basket was made to take precautions against the sterile article pollution after disinfection from boiler disinfection and also for convenience. Methods Items after disinfection from 100 pots were randomly allocated to the observation group and the control group, each group had 50 pots.The observation group used the high-pressure-vapor disinfection basket to take the items from the sterilization room to the disinfection room directly. The control group used conventional disinfection cart, re-moved the items to the cart,thon took them to the disinfection room. Time cost for convey of the disinfection items was observed,and surface sampling for gormiculture was obtained from the last item conveyed to the disinfection room. Results After germiculture,2 pollution packets were found in the observation group,the polluting rate was 4%;49 pollution packets in the control group,the polluting rate was 98%,which was statistically different from that of the observation group(P<0.01). Time cost of the observation group was 8 minutes,of the control group was 13 minutes. Conclusions Use of the portable,pollution-prevention and high-pressure-vapor disinfection basket can prevent the surface of disinfection items from pollution,besides,it is convenient and costs less labor and time.

Parenteral nutrition (PN) is one of the important measures to cure premature babies and critically ill infants.In recent years,with the improvement of rescue techniques in the perinatal period,a growing number of preterm infants alive,very low birth weight and low birth weight infants gradually become an important part of the neonatal disease.The gastrointestinal development of these premature babies are not mature or combined with other diseases,in a long period of time after birth need partial or complete PN support.Due to the use of PN,provides the children with survival and greatly reduce the case fatality rate,but the cause of parenteral nutrition associated cholestasis would become one of the main complications of premature infants,seriously affect the patient's quality of life.In this paper,the treatment of premature parenteral nutrition associated cholestasis status is summarized.

Protection for privacy is the guarantee for sustaining personal dignity and individual liberty.Protection for patients' privacy has a long history and is of great realistic significance.However,patients with A H1N1 Influenza are facing the risk of exposing privacy in current circumstances.This paper argues that the privacy protection for this particular population is beneficial both for social and public interests,and also can be justified from an ethical perspective.

OBJECTIVE:To prepare granisetron hydrochloride nasal spray and establish a method for its quality control. METHODS: Granisetron hydrochloride nasal spray was prepared using granisetron hydrochloride as chief ingredient and its content was determined by UV spectrophotometry. RESULTS: Spray appeared as colorless or yellowish supernatant liquid and it was up to the standard specified in Chinese Pharmacopeia (2005 edition). The linear range of granisetron hydrochloride was 105.9～635.4 ?g?mL-1 (r=0.999) and its average recovery rate was 100.1% (RSD=0.4%). CONCLUSION: The preparation is simple and feasible in preparation process and its quality is controllable.

Microphthalmos is a developmental disorder of the eye consisting of a smaller cornea,coloboma of iris and choroid and nystagmus.It can present as an isolated disease or associate with other systemic disor- ders.Cataract commonly occurs in these eyes.Ten eyes which received cataract extraction and intraocular lens implant were reviewed in this paper.If the diameters of the cornea are smaller than 8mm,the surgical results arc not good;otherwise it is safe and successful.

Objective To explore the relation between the blood glucose and the clinical aspects of acute bischemic stroke.Methods 164 patients with acute cerebral infarction were divided into threegroups:normal glycemic group,diabetes hyperglycemic group and non-diabetes hyperglycemic group.To study the relation between blood glucose and clinical aspects of bischemic stroke.Results There were significant differences in curatio improvement rate among the three groups(P

OBJECTIVE:To improve the classified drug control level and drug supervision in China by drawing advanced experiences from Germany.METHODS:The laws and regulations,standards for classified drug control in Germany were introduced.RESULTS & CONCLUSIONS:The humanized management,the management model on narcotic drugs,adopting advanced equipment and informationized management in Germany serve as a model for China to follow.

Objective To observe the curative effect of fresh amniotic membrane and biotic amniotic membrane grafting for treating eye burn in early stage. Method We collected 19 cases (19eyes) with burn in ocular surface treated in our hospital from January 2006 to March 2007. The 19 cases were divided into two groups. One group was treated with amniotic membrane grafting (FAMG) and the other group was treated with biotic amniotic membrane grafting(BAMG) ,with follow time of 3 ～ 18 month after operation. Results After opera-tion, all the grafted membranes in the 19 cases survived. The corneal epithelium was well healed without rejection and secondary infection. No symblepharon or corneal neovascularization was noted and the vision improved with different degree. Conclusion Both fresh amniotic membrane and biotic amniotic membrane are used for recovering the ocular surface to cure bye burn and biotic amniotic membrane has the same curative effect as compared with fresh amniotic membrane.

Lactose is one of the important nutrients in milk.It is decomposed by the lactase enzyme and plays an important role in the life activities of cells in human health.Due to the lack of lactase,the symptoms of lactose intolerance occur highly in Chinese population,thus limiting the large part of the people to drink milk.Milk is a good source of high-quality protein,minerals and vitamins for the human,so the problem of lactase deficiency also seems particularly severe.
