Objective To investigate the current policy of medical insurance expenditure control in Shanghai and put forward feasible advice. Methods Survey in 5 tertiary first-class hospitals in Shanghai involving 400 doctors and patients was conducted.The result of the questionnaire was tracked with Microsoft Excel 2000.The expense reports during 2001 to 2006 from the Office of Medical Insurance of Shanghai Renji Hospital was collected.All the data were statistically analysed. Results The global budget system was accepted by both the doctors and patients.Charging based on disease categories was proved a relatively satisfying method.Drug expenditure control was concerned by both the doctors and patients. Conclusion Ever since the global budget system of medical insurance is implemented in Shanghai,the medical insurance expenditure has been effectively controlled.The key point is the restraint of irrational consumption during the medical treatment.

To improve the precision of image registration based on corner detection, a relative position function between multiple points to determine matching points accurately. First the corners in images are detected using Harris detector, and clustering method is used to eliminate most wrong matches after coarse screening. Then the proposed relative position function is used as a criterion of precise matching. Finally the image registration process is accomplished by affine transformation. Results show that the proposed algorithm is more effective and accurate than conventional registration algorithm.

ObjectiveTo investigate the language cortex organization characteristics of native Chinese. Methods20 patients who underwent language mapping via intraoperative direct cortical electrical stimulation (ioDCES) under awake anaesthesia for glioma in dominant hemisphere were analyzed retrospectively. Results16 patients were identified at least one language site, 3 patients located in the frontal and 1 patient in the temporal lobe. The language sites mostly located in the perisylvian region. The frontal language sites conformed to traditional Broca's areas, but the superior temporal gyrus contained much more language sites than the middle temporal gyrus.ConclusionHigh individual variability in language organization indicates a need for revision of the classical model of language localization. Because of the samples were too small, our current dates can't fully reflect language cortex organization characteristics of native Chinese.

Objective:To compare the therapy effects of chemotherapy and non-chemotherapy groups and to determine the value of chemotherapy for adult diffuse low-grade gliomas. Methods:We reviewed and analyzed 64 patients with adult diffuse low-grade glio-mas admitted to the Beijing Tiantan Hospital from May 2005 to April 2008. Among the patients, 18 received 4 to 12 cycles of temozolo-mide chemotherapy after operation and radiotherapy, whereas the other 46 cases only received radiotherapy. The progression-free survival of the two groups was compared. Results:The median progression-free survival of the chemotherapy and the control groups were 67.8 and 51.3 months, respectively. The results of the comparison implied a significant difference (χ2=8.741, P=0.003). Conclu-sion:Chemotherapy can improve the progression-free survival of the patients with adult diffuse low-grade gliomas, and thus, can be recommended as its effective therapy.

OBJECTIVE:To evaluate the therapeutic effect of clarithromycin on prostatitis induced by NG,CT and U?U.METHODS:56cases of venereal disease-related prostatitis were treated with oral clarithromycin in combination with prostatic massage and hip bath.7days after withdrawing drug,examination of prostatic secretion(EPS)and detection of pathogens were carried out.RESULTS:Total effective rate was82.1%;negative turn rate was92.9%;87.5%EPS routine came back to normal;no obvious ARDs were found.CONCLUSION:Clarithromycin is high in therapeutic effect,slight in ad?verse reactions and convenient in administration.It is suitable for treatment of venereal disease-related prostatitis.

Objective To observe the curative effect of lumbar sympathetic nerve injury combined with systemic and local medication in intractable lower limb ischemic pain.Methods21 patients with intractable lower limb ischemic pain accepted lumbar sympathectomy,at the same time foot topical Votalinemulgel used and Combined with anticonvulsants and opioids according to circumstances,the visual analogue scale of resting pain(visual analogue scale,VAS),the Local skin temperaturebefore and after treatment were observed and evaluated.ResultsAfter Lumbar sympathetic nerve block and topical Votalinemulgel,21 patients had pain relief.After treatment, 2 patients had poor effect,the remaining 19 patients had pain relief to VAS<3, 4 patients did not need systemic analgesic drugs,the rest of the patients need systemic analgesic drugs.ConclusionIt is necessary to adopt multimodal comprehensive treatment for intractable lower limb ischemic pain.

Objective To evaluate the role of hippocampal histone acetylation in isoflurane-induced amnestic effect in mice.Methods Fifty-four male C57BL/6J mice,aged 8 weeks,weighing 18-22 g,were randomly divided into 3 groups (n =18 each) using a random number table:control group (group C),isoflurane group (group ISO) and histone deacetylase inhibitor sodium butyrate group (group SB).Group C inhaled 35％ oxygen for 30 ain,and ISO and SB groups inhaled the mixture of 35 ％ oxygen and 0.4％ isoflurane for 30 min,and then the animals underwent contextual fear conditioning training.After the end of training,normal saline 6 ml/kg was intraperitoneally injected in C and ISO groups,while in group SB,sodium butyrate 1.2 g/kg was intraperitoneally injected.One hour after the end of training,3 mice were sacrificed randomly in each group and their hippocampi were immediately removed for determination of the expression of acetylated histone-H3 (Ac-H3) and Ac-H4 by Western blot.Twenty-four hours after the end of training,contextual fear conditioning test and open field test were conducted.The freezing time,total distance and time of staying at the central zone were recorded.Results Compared with group C,Ac-H3 and Ac-H4 expression was significantly down-regulated,and the percentage of freezing time during testing was decreased in group ISO (P ＜ 0.05).Compared with group ISO,Ac-H3 and Ac-H4 expression was significantly up-regulated,and the percentage of freezing time during testing was increased in group SB (P ＜ 0.05).There was no significant difference in the percentage of freezing time during training,total distance and time of staying in the central zone among the 3 groups (P ＞ 0.05).Conclusion Hippocampal histone acetylation is involved in the regulation of isoflurane-induced amnestic effect in mice.
