Objective To evaluate the effect of calcitonic gene related peptide(CGRP) and endothelin(ET) on acute and delayed cerebral vasospasm(CVS) after subarachnoid hemorrhage(SAH).Methods The SAH model in rabbit were established by single injection of autologous arterial blood(0.5 ml/kg) to cisterna magna on percutaneous suboccpital route. Transcranial Dopper(TCD) was performed to detect the spastic of rabbit basilar artery(BA). The CGRP and ET concentrations in cerebrospinal fluid were examinated quntitatively by radioimmunologlc techniques at 30 minutes, 3 days, and 5 days after SAH.Results The results of TCD showed that rabbit basilar artery was spastic at 30 minutes, 3 days and 5 days after SAH. At 30 minutes after SAH, CGRP concentration significantly increased upto about 18 fold( P

To prepare decalcified bone matrix particles(DBMP)with adriamycin(ADM) impregnated bone cement(BC) drug delivery system(DDS), its drug delivery characteristics were studied and analysed in vivo. DBMP were made according to the methods of Urist et al. ADM was putting into DBMP by vacuum absorption and freeze drying techniques. Then the DBMP with ADM were impregnated into BC in 1∶1 to form DDS. The DDS was implanted into the greater trochanter of femur in rabbits and the release test was done in vivo. The DDS could gradually release ADM for over 12 weeks in local bone tissues, maintained stable release for 4 weeks. The maximum ADM in local bone tissues was 29 times higher than that of the same intrarenous dose, while the maximum ADM in plasma was only 1/10 of the same intravenous dose. The DDS has a good sustained release function, and can meet the needs of local chemotherapy for limb salvage treament of bone tumor.

Objective To evaluate and compare open and retroperitoneal laparoscopic adrenalectomy.Methods Clinical data of 30 cases undergoing open adrenalectomy and 119 cases undergoing retroperitoneal laparoscopic surgery were retrospectively analyzed. The 2 groups were compared in terms of these aspects: operation duration, intraoperative blood loss, postoperative analgesic use, time to remove drainage tube, time to resume eat, postoperative hospitalization time, complications, and tumor recurrence. In open surgery group, tumor diameter was between 0.5 cm -10.8 cm, 4.57 cm in average. 18 tumors were located on the left side and 12 tumors on the right side. In laparoscopic group, tumor diameter was between 0.8 cm -14.5 cm, 2.78 cm in average. 59tumors were located on the left side and 60 tumors on the right side. Patients in open surgery group were followed up for 6-72 months and retroperitoneal laparoscopic group 4-20 months. Results Open adrenalectomy were successful in all the 30 cases. 12 cases in laparoscopic surgery group converted to open surgery among whom 8 cases were due to poor visibility, 1 case due to renal artery injury, 1 case due to large tumor size, 1 case because of diaphragmatic injury and 1 case because of pleural injury. Laparoscopic surgery was superior to open surgery in terms of operation duration, intraoperative blood loss, postoperative analgesic use, time to start food taking, time to remove drainage tube, and postoperative hospitalization time. The difference had statistical significance (P ＜0.05 ). Conclusion Retroperitoneal laparoscopic adrenalectomy has advantages such as less trauma, less blood loss, and shorter recovery time, which make this procedure the modern golden standard for treatment of benign adrenal neoplasm.

This study evaluated the effects of teaching methods through questionnaire and score analysis of the two groups.Results Students taught by project draft design combined with PBL teaching method generally believed that this teaching method can stimulate their learning interest, improve their ability of locating problems, solving problems, and comprehensively applying knowledge and enhance test scores.Conclusion Project draft design combined with PBL teaching method shows better teaching outcomes than traditional teaching method, which can cultivate students’ all-round ability and comprehensive quality.

Objective To analyze the policy support of rural doctors for the essential medicine system,and explore the main influence factors and mechanism affecting the support degree.Methods 621 rural doctors from five cities in Shandong province were subject to a stratified random sampling for a quantitative questionnaire,to build a hypothesis model of policy support of rural doctors,which is verified using factor analysis and path analysis.Results 59.1% of rural doctors support the essential drugs policy.It was found that the essential medicine factor,the factor to influence the practitioner,and the supporting policy factor had a direct impact on policy support of rural doctors,with the effect of 0.305, 0.1 59 and 0.135 respectively;Essential medicine factor and the supporting policy factor indirectly influence the policy support of rural doctors through the factor to influence practitioners,with the effect of 0.065 and 0.032 respectively.Conclusion The essential medicine system needs to emphasize such rationality as the quality,list and pricing of essential medicines;it is imperative for the government to better oversee the purchase and supply of essential drugs,to cater to the interests of rural doctors,to encourage the enforcement of the system,and promote the development of village clinics.

Background and purpose: High-dose chemotherapy followed by autologous stem cell transplantation (auto-HSCT) is considered as the ifrst line treatment for patients with relapse/refractory lymphoma after conventional chemotherapy. However, most of these patients still relapse the second time. The purpose of this study was to analyze the efifcacy of the consolidation chemotherapy after autologous stem cell transplantation (HSCT) refractory/relapse lymphoma in high risk. Methods:A total of 38 patients with relapsed/refractory lymphoma including Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) were included, who were underwent auto-HSCT in our transplan-tation department from Jan. 2010 to Dec. 2013. In treatment group, 19 patients received 2 courses of consolidation che-motherapy after auto-HSCT every 2 to 3 months, with the regimen of mini-BEAM or modiifed mini-CBV. Another 19 patients had no chemotherapy after auto-HSCT as control group. Results:The median follow-up duration was 17.2 and 7.5 months in the treatment and control group respectively. The follow-up data demonstrated prolonged progression-free survival (PFS) in the treatment group than the control group [24.7 months vs 7.8 months, P=0.029 under intend-to-treat analysis ITT;24.7 months vs 5.2 months, P=0.01 under per protocol analysis(pp)]. There is also a trend of improved overall survival (OS) in the treatment group (P=0.055, ITT). Conclusion:Consolidation chemotherapy after auto-HSCT for refractory/relapsed lymphoma patients delay the relapse and tend to improve the overall relapse rate.

Objective:To study the effects of smokeless tobacco extract(ST)on the proliferation and the heat shock protein 70 (HSP70)expression of human periodontal ligament cells(hPDLCs).Methods:hPDLCs were cultured in vitro and identified by im-munohistochemistry(IHC).The cells were stimulated with ST at 0.01 6 -50 g/L respectively for 24 h,the proliferation was examine by MTT assay,HSP70 expression was detected by immunehistochemical staining and Western Blot.Results:ST inhibited the prolifer-ation and increased HSP70 expression in cytoplasm and nucleus at 0.4 -50 g/L dose dependantly.Conclusion:ST may inhibit the proliferation and increase HSP70 expression of hPDLCs in a dose depandant manner.
