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.

In mice, adriamycin (l7.5mg/kg, ip ) produced heart peroxida-tion abnormality including increased TBA value & decreased gluta-thione peroxidase activity, respectively. But the change of former was not parallel to the latter. The drug also produced early pathological change of the heart i.e. more D-PAS positiveness. The results suggested that the early heart pathological change produced by adriamycin may be related to increased accumulation of pero-xi dative products.

OBJECTIVE: To analyse the situation of use of therapeutic drugs for benign prostate hyperplasia(BPH) in hospitals of Shanghai and to make OBJECTIVE: evaluation as reference for production,sale and consumption departments.METHODS: To investigate the BPH drugs used in 47 hospitals of Shanghai during the 1999 - 2001 period in respect to the amunt of consumption, kinds, sum of money of consumption, DDDs and clinical evaluation .RESULTS: Consumption of BPH drugs was increasing in recent years, but kinds of drugs had no obvious change, major drugs for BPH were Finasteride, Tamsulosin and Prostat .CONCLUSION: Therapeutic drugs for BPH are common drugs, but price is very expensive.To speed up the reseach and development of drugs in our country and to advocate the use of domestic products are suggested.

OBJECTIVE:To get a clear idea about the situation of application of hypolipemic agents in hospitals of Shanghai so as to provide information for departments of production,sale and consumption METHODS:The kind,amount,sum of money and DDDs of hypolipemic agents,used in 47 hospitals in Shanghai during the period 1999～2001,were analysed RESULTS:Vastatin,Fibrate and Chinese materia medica were the most commonly used drugs;Simvastatin,Zhibituo and Fenofibrate occupied the front places in amount of consumption;The sales volume of Zocor(Simvastatin)Pravachol and Xuezhikang was at the top of list;Simvastatin,Fluvastatin,Xuezhikang and Fenofibrate revealed increasing tendency and Gemfibrozil,Zhibituo,Duoxikang and Chondroitine showed decreasing tendency in clinical use CONCLUSION:The market prospects of hypolipemic agents will be wide and bright

Objective To study the clinical characteristics,pathologic change,surgical treatment and survival rate of primary hepatic carcinoma complicated with cancer embolus of biliary tract (PHC-CEBT).Methods Case analysis data,clinical manifestation and pathological findings of 16 cases of PHC were comprehensively analyzed in our hospital.Results No death case was seen after resection. The survival time of 2 patients without tumor resection were 2 5～4 5 months,other 14 patients with tumor resection were 1～4 5 years.Conclusions Surgical operation treatment of PHC-CEBT is effective,it can increase the survival rate and improve life quality.

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.
