Cell adhesion molecules (CAMs) are involved in glycoproteins expressed on cell surfaces which play an essential role in clinical disorders. At present, there are several groups of anti inflammatory drugs interfere with the expression of CAMs either directly or indirectly. This paper reviews the study of recent finding pharmacological agents associated with CAMs.

To retrospectively analyze the clinical data of 305 cases with apoplectic sequela admitted at our general geriatric nursing ward from January 2000 to December 2011.The subjects were divided into 2 groups:hypoalbuminemia and non-hypoalbuminemia.Advanced age (OR =5.624),chronic heart failure (OR =2.298),conscious disturbance (OR =1.575),dysphagia (OR =1.565),complete bedridden (OR=2.874),pneumonia (OR =3.725) and bedsore (OR =5.336) were risk factors for hypoalbuminemia in the patients with apoplectic sequela.And hyperglycemia(OR =0.066)was a protective factor for it.

To date, three techniques of total spondelyctomy were used for spinal tumor, including piecemeal technique, eggshell technique and total en bloc spondelyctomy, and each has specific features and indications. Due to limitations of technique, piecemeal technique and eggshell technique are gradually replaced by total en bloc spondelyctomy in treatment of spinal tumor. Moreover, with technical development, application of total en bloc spondelyctomy in treatment of spinal tumor becomes more rigorous and standard. However, it is controversial about its indications and surgical approach. Postoperative spinal stability reconstruction is achieved through various methods according to different conditions.

Therapeutic hypothermia is believed to improve neurodevelopment outcome of infants with moderate-to-severe hypoxic-ischemic encephalopathy(HIE),however,the severe brain injury and neurologic sequelae still can be observed in some infants received therapeutic hypothermia.Optimal monitor and management of systematic complications presented by infants during cooling treatment are necessary for improvement of overall outcome.Therefore,it is essential to understand the functional change of each system of the whole body,to adapt adequate diagnostic methods and to train multidisciplinary staffs to monitor and manage moderate-to-severe HIE infants during therapeutic cooling.With the development of therapeutic hypothermia,it is currently considered as a standard of care for infants with moderate-to-severe HIE.It is recommended that any neonatal intensive care unit(NICU) using routinely therapeutic hypothermia to reference the national or international benchmarking protocols in order to improve the medical quality and prognosis of infants.

BACKGROUND: Inadequate hyperventilation may trigger cerebrovascular contraction and lead to lowered cerebral perfusion and oxygen supply-demand imbalance.OBJECTIVE: To investigate the influence of hyperventilation on oxygen saturation in the internal jugular vein, difference in oxygen and lactic acid contents between the cerebral arteries and veins in patients with serious traumatic brain injury.DESIGN: Case analysis.SETTING: Department of Anesthesiology, First Hospital Affiliated to Shantou University.PARTICIPANTS: Sixteen patients who received emergency operations in the First Hospital Affiliated to Shantou University between January and July 2002.METHODS: Patients with traumatic brain injury underwent operation under general anesthesia, and the PaCO2 was maintained at 30 mm Hg for 15 minutes by regulating the respiration rate, followed by decrease to 25 mm Hg, maintained for 15 minutes before restoration to 30 mm Hg for 15 minutes. The fractional concentration of inspired oxygen was adjusted to maintain blood PaO2 at around 100-150 mm Hg, and the blood sample was collected from the artery and internal jugular vein 15 minutes after adjustment of PaCO2 for blood gas analysis. The PaO2 was then increased to 200-250 mm Hg by increasing the fractional concentration of inspired oxygen, and the PaCO2 was adjusted from 30 to 25 and then back to 30 mm Hg in the described manner, and the oxygen saturation in the internal jugular vein, difference in oxygen and lactic acid contents between the arteries and the veins were measured.MAIN OUTCOME MEASURES: Influence of blood PaO2 and PaCO2 on oxygen saturation in the internal jugular vein, difference in oxygen and lactic acid contents between the arteries and the veins.RESULTS: Sixteen patients met the diagnostic criteria and completed data collection. The arterial PaCO2 decreased from 30 to 25 mm Hg when arterial blood oxygen pressure increased from 100-150 to 200-250 mm Hg, which leads to obvious decrease of oxygen saturation in the internal jugular vein and obvious increased difference in oxygen content between the cerebral artery and vein. However the absolute value of oxygen saturation in the internal jugular vein was obviously higher at PaO2 of 200-250 mm Hg than that at PaO2 of 100-150 mm Hg, while the absolute value of cerebral arteriovenous difference of brain oxygen content was obviously lower. Compared to the basal level, the arteriovenous lactic acid difference was obviously increased at PaO2 of 100-150 mm Hg,PaCO2 of 30 and 25 mm Hg, and at PaO2 of 200-250 mm Hg and PaCO2 of 25 mm Hg.CONCLUSION: Relatively higher PaO2 (200-250 mm Hg) and mild hyperventilation (PaCO2 of 30 mm Hg) has no obvious effect on brain oxygen supply-demand balance.

With the development of all kinds of new simulative training equipment,the way of medico's clinic skill training method will change radically.Their clinic skill will be greatly improved.This article analyzed the necessities and imminence of setting up the clinic skill training center,and discussed how to manage it.At last we discussed how to build the clinic skill training center in the large comprehensive hospitals.

Restenosis is a major complication after percutaneous transluminal coronary intervention. Evaluation of restenosis early and accurately can help to giude treatment, improve outcome and save costs for the patients. All kinds of imaging methods for restenosis have their merits and demerits. It is essential to choose the appropriate imaging method in clinical practice.

Objective To establish a method for the quantitative determinations of the ingredients in yiqi hewei capsules. Methods RP-HPLC method was used. The separation was performed on a Thermo C18 column with mobile phase consisting of acetonitrile-water (20: 80) (pH was adjusted to 3 with glacial acetic acid) at the flow rate of 1. 0 mL·min-1. The detection wavelength was 283 nm. Results The linear ranges were ( 0. 5735 -5. 7360) × 10 -2 mg·mL-1 for baicalin, (0. 1940-1. 9395) × 10 -2 mg·mL-1 for hesperidin, (0. 2051 -2. 0510) × 10 -3 mg·mL-1 for naringin and (0. 2020 -2.0200) ×10 -2 mg·mL-1 for neohesperidin;RSD =0.28%,0.54%,0.54%,0.31%(n =5),respectively. The average recoveries were 103. 94%, 98. 06%, 103. 09%, 95. 67%, respectively. Conclusion The established method is simple, sensitive and accurate,which can be used for the quality control of yiqi hewei capsules.

In the article, it thinks that moral lacking of advertisement is the basic reason which leads to intensified illegal medical advertisement. The main reasons for moral lacking of advertisement: imperfect legal system of medical advertisement, indifferent ethical consciousness of medical advertisement, insufficient social supervision of medical advertisement. Therefore, we should perfect the legislation, establish the correct advertising moral concept, improve the quality of advertising employees, and realize the function of social supervision fully.
