Headache is a common clinical symptom.Some headache disorders belong to secondary category.Many intracranial disorders,such as head trauma,cerebral vascular diseases,intracranial tumors and inflammation,can lead to headache due to mass effect,inflammation reaction,stimulation of vasoactive substances and decreased intracranial pressure.Furthermore,many drugs and other substances,disorders of eyes,nose,ear,mouth,neck and other systemic disorders can also cause headache.Many headache disorders can be determined by detailed case history and physical examination.Blood test,lumber puncture,CT,MRI and other imaging examinations are necessary methods for finding the causes and the treatment of diseases.

Objective:To investigate the operation technique and the effect of the posterior microendoscopic discectomy (MED) system on lumbar intervertebral disc hermiation (LIDH). Methods: We retrospectively reviewed and analyzed 25 cases of LVDH treated with the MED system from March 2004 to August 2005. Results: All the patients were ambulant 20 hours to 7 days (mean 2.4 days) after the operation, with a mean hospital stay of 5.2 days. And all were healed within the first stage except 1 case of infection. The patients were followed for 2-15 months (mean 6 months). Excellent results were achieved in 18 cases, good results in 5 and fairly good results in 2, the first two groups making up 92%. Conclusion: The key to successful MED with no complications is familiarity with the equipment, proper choice of indication, exact surgical location and skilful operation.

Aim To examine subcellular localization of serotonin 5-HT2A receptor (5-HT2AR) and glutamate NMDA receptor in dorsal hippocampal CA1 area ( dCA1 ) and further explore the effect of systemic acti-vation of 5-HT2A R on hippocampal neuronal firing rate. Methods The distribution of 5-HT2A R and NMDA re-ceptor in the dCA1 region was detected with immune e-lectron microscopy after embedding. The effect of acti-vation of 5-HT2A R on the principal neuron and inter-neuron firing rates was examined with multichannel re-cording. Results 5-HT2A R immunoreactivity was ob-served in the dCA1 neurons, including rough endoplas-mic reticula and mitochondria, and the 5-HT2A R and glutamate NMDA receptors were colocalized in the syn-aptic membrane, vesicle and neurofilament of the hipp-ocampal neuron. 5-HT2A R activation increased princi-pal neuronal firing rate and the interneuronal firing rate was not changed. Conclusion The 5-HT2A R and NM-DA receptor are colocalized in dCA1 neurons, and acti-vation of 5-HT2A R increases hippocampal principal neuronal firing rate.

Objective To analyze the recent changes in features of joint injury caused by the fast running railroad train. Methods 1279 joint injuries o f the 10214 cases of train injury after the speeding up of the railway services from 1997 to 2003 were analyzed to find out their particular causal conditions, the severity of the injury, and the classification of the injuries, the correlat ion between which and recovery was also tested by AIS-ISS grading. Results Afte r the speeding up of the railway services, the incidence of joint injuries rose from 33.54% to 34.12%,the mortality rose from 22.88% to 30.33%,the multipl e joint severances rose from 19.84% to 34.19%,the open joint injury rose from 31.71% to 63.15%,and the mortality caused by multiple joint severances rose from 21.19% to 49.07%. Conclusions The incidence of multiple traumas resulted from the train is much higher than those resulted from other causes. Multiple t raumas caused by train are very difficult to deal with. The multiple organ dysfu nction syndrome (MODS) is a main factor to cause the death.

Objective To observe the application effect of mental nursing on perioperative nursing of patients. Methods 66 patients with cutaneous carcinoma were randomly divided into the conventional nurs-ing group and the psychological intervention group. The conventional nursing group received perioperative mu-fine nursing,the psychological intervention group was given mental intervention before,during and after operation based on routine nursing. The anxiety value was measured before and 30 minutes after the operation, pain de-gree was assessed 30 minutes after the operation,the results underwent t test and X2 teat. Results Compared to the conventional nursing group, the anxiety value before the operation and 30 minutes pestoperation as well as pain degree 30 minutes pestoperation of the psychological intervention group were significantly decreased. Conclusions Mental nursing of patients with cutaneous carcinoma can efficiently eliminate or re-duco patients' psychologic obstacle and significantly reduce patients' painful feeling.

As a tool, cholelithiasis animal models have become an important platform for pathogenetic, preventative, diagnostic and therapeutic research. As biliary calculus formation has a close relationship with dysfunction of hepatic and biliary systems, inability of lipid metabolism homeostasis and impairment of immunologic barriers, increasing studies have been carried out with the use of animal models in these fields. Animal genetic susceptibility to cholelithiasis has greatly attracted people's attention in recent years and cholelithiasis animal models have been used in Chinese traditional medicine development and authentication. Furthermore, reports on invasive and traumatic research have been published in which large animal models were used. It is supposed that technical progress and scientists' demands would result in wide application of more kinds of cholelithiasis animal models.

BACKGROUND: To summarize the feature and clinical application of various injectable bone substitutes.DATA SOURCES: The computer-based research was done in Pubmed database for articles concerning various injectable bone substitutes published from January 1995 to May 2009 with the key words of "injectable bone substitute, bone injury" in titles and abstracts. Literatures of the same fields published in recent years or in authorized journals were selected.DATA SELECTION: Latest literatures addressing feature and clinical application of various injectable bone substitutes were selected; old and repetitive studies were excluded. Finally, 21 articles were included.MAIN OUTCOME MEASURES: Feature and clinical application of various injectable bone substitutes were measured.RESULTS: Present various injectable bone substitutes contained complex hydroxyapatite bone substitutes, complex calcium sulfate bone substitutes, and complex calcium phosphate bone substitutes. Addition of bone morphogenetic protein-2 etc. in injectable bone substitute could significantly elevate bone union speed, promote osteoblastic proliferation, and overcome disadvantage of physical bone substitute to some degrees. Addition of platelet-rich plasma could promote repair effect of injectable bone substitute on bone defects, and promote differentiation of bone marrow stromal stem cells and proliferation of osteoblasts. Addition of cells could make up the insufficiency of physical materials to great degrees.CONCLUSION: The compound injectable bone substitute has a bright perspective of clinical application. Injectable bone substitutes combined with cells (especially stem cells) will be a new direction for biomaterial development in the future.
