Objective To investigate the clinical and angiographic features in hemorrhagic moyamoya disease patients with the posterior circulation involvement (PCI). Methods The clinical and imaging data of 224 patients with hemorrhagic moyamoya disease from December 2002 to December 2011 were analyzed retrospectively. The patients were divided into either a PCI group (n=57)or a non-PCI group (n=167) according to whether they had PCI or not. Results (1)Suzuki staging concentrated in stageⅤandⅥin the PCI group,accounting for 42. 1%(24/57)and 40. 4%(23/57)respectively;Suzuki staging concentrated in stage Ⅲ and Ⅳ in the non-PCI group,accounting for 31. 1%(52/167)and 41. 9%(70/167)respectively. There was significant difference in the distribution of Suzuki staging between the patients of both groups (P <0. 01). (2)In the PCI group,the thalamic hemorrhage,intraventricular hemorrhage,ganglia hemorrhage,subarachnoid hemorrhage accounted for 43. 9%(26/57),38. 6%(22/57), 3. 5%(2/57),14. 0%(8/57),respectively;There was no cerebral lobe hemorrhage. In the non-PCI group, the thalamic hemorrhage,intraventricular hemorrhage,basal ganglia hemorrhage,subarachnoid hemorrhage and cerebral lobe hemorrhage accounted for 0,37. 7%(63/167),25. 1%(42/167),15. 6%(26/167),21.6 (36/167),respectively. The proportion of hemorrhage types between the PCI group and non-PCI group was significantly different(P<0. 01). (3)The dilation of anterior,posterior choroidal artery ,and patency of posterior communicating artery,posterior pericallosal artery in bleeding side accounting for 19. 3%(11/57),82. 5%(47/57),36. 8%(21/57),78. 9%(45/57)in PCI group and 36. 5%(61/167),3. 0%(5/167),68. 9%(115/167),80. 2%(134/167)in non-PCI group. The ratio of of abnormal vessels between PCI group and non-PCI group had significantly statistical difference (P<0. 01). Conclusion Hemorrhagic moyamoya with PCI is common. Suzuki staging is usually in the advanced stage of vascular staging of moyamoya disease. The thalamic hemorrhage is the main type of bleeding. Posterior choroidal artery rupture may be the main reason of hemorrhage.

Acute myocardial infarction (AMI) is caused by acute occlusion of the coronary artery. The partial necrosis of the myocardium is caused by severe and prolonged ischemia,which is characterized by persistent and severe chest pain, the high mortality rate. Fast recovery can be achieved the coronary artery blood circulation by emergency percutaneous coronary intervention (PCI), can improve myocardial is-chemia, save moribund myocardium. The medical profession is generally believed that on the basis of en-suring the safety of patients with AMI, the normal rehabilitation should be carried out as soon as possible. In this article, the domestic in recent years, AMI emergency PCI in early postoperative rehabilitation treatment method, the intensity and evaluation index of three aspects were summarized. The starting time of the early rehabilitation of AMI patients in foreign countries is earlier than our country. As we all know that via radial artery PCI has the smaller puncture and more convenient hemostasis, so there is no doubt that it can pro-vide favorable conditions for recovery of patients. Therefore, it is necessary to expand the research field in order to determine the best rehabilitation opportunity and the most excellent rehabilitation program , so as so determine the best recovery time and the most excellent rehabilitation program in patients with AMI after PCI operation.

Objective: To investigate the proliferation of three subtypes of odontogenic keratocysts(OKC), namely simple(not recurrent),recurrent and basal cell naevus syndrome(BCNS) associated lesions. Methods: Ki 67 expression was studied in 34 odontogenic keratocysts(simple, n =10;recurrent, n =12;syndrome, n =12)by biotin streptavidin method using Ki 67 monoclonal antibody after microwave treatment. Ki 67 positive cells were counted manually and related to the area of epithelial lining as determined by computer image analyzer. Results: Ki 67 positive cells per mm 2 in simple odontogenic keratocysts ①, recurrent odontogenic keratocysts ② and BCNS ③ were 1 812.29?606.47, 2 393.88 ?997.08 and 3 983.17?858.92 respectively(① or ② vs ③ P 0.05). Conclusion: The basal cell naevus syndrome associated OKC has a higher rate of epithelial proliferation than non syndrome OKC, the increased epithelial proliferation is correlated with increased recurrence potential. Ki 67 may be an alternative method to differentiate syndrome and non syndrome OKC.

Objective To evaluate the long term efficacy of radical cystectomy and ileal conduit in the treatment of bladder cancer. Methods 196 cases of bladder tumor treated from Jan. 1985 to Jan. 2000 with radical cystectomy and ileal conduit for urinary diversion were studied retrospectively. Results Bladder neck or trigone was involved by the neogrowth in 126(64.3%).The growth has been invasive in 145(74.0%). 93.4%(183/196) of the tumor were transitional cell carcinoma. Early operative complication occurred in 19(9.7%) and late complication in 10(7.4%).On following up for 1 to 15 years with a mean of 6.6 years,the 5 year survival rate has been 66.2%. Conclusions Radical cystectomy is the optimal in treating invasive bladder tumor and ileal conduit is a good means of urinary diversion which is simple with minimal complications.

Objective·To explore the diagnostic value of 9 mTc-sestamibi (9 mTc-MIBI) single photon emission computed tomography/computed tomography (SPECT/CT) and ultrasonography in hyperparathyroidism. Methods·Fifty patients with hyperparathyroidism were included. 9 mTc-MIBI SPECT/CT was performed before operations in all patients, while ultrasonography was performed in 33 patients. The diagnostic efficiency was calculated for both imaging methods in comparison to pathological data. Results·Serum parathyroid hormone (PTH) levels were 352.0 (141.5-846.0) pg/mL and 1792.0 (1018.5-2358.5) pg/mL, respectively, in primary hyperparathyroidism (PHPT) and secondary hyperparathyroidism (SHPT), while maximum diameters of lesion were 14.5 (9.0-20.9) mm and 10.0 (8.0-12.6) mm, respectively (both P<0.01). The accuracy of SPECT/CT were 97.7% and 62.5%, respectively (P<0.01), in PHPT and SHPT. In 33 patients, the sensitivity and accuracy of SPECT/CT were 66.3% and 74.2%, respectively, whereas the sensitivity and accuracy of ultrasonography were 45.7% and 61.4%, respectively (both P<0.05). Conclusion·Serum PTH levels were higher, while maximum diameters of lesion were longer in PHPT than that in SHPT, and the diagnostic efficiency was also higher in PHPT than that in SHPT. In the other hand, the sensitivity and accuracy of SPECT/CT were higher than that of ultrasonography.

Objective: To extract the volatile oil in Semen Ocimi Basilici(SOB),determine the chemical con- stituents of the volatile oil extract the polysaccharide from the SOB residue after extracting the volatile oil,and analyze the monosaccharide compositions of the polysaccharide. Methods: The SOB volatile oil was extracted by the simultane- ous distillation and extraction(SDE)method and by the conventional method of steam distillation,respectively,and the chemical constituents of the oils were analyzed and identified by the gas chromatography- mass spectrometry(GC- MS). Polysaccharides in the SOB residues were obtained by the water extraction,followed by the alcohol precipitation,and the monosaccharide compositions of the polysaccharide were analyzed by the thin layer chromatography (TLC). Results In total 51 compounds were identified in the SOB volatile oil extracted by the SDE method,accounting for 91.76% of the total oil amount,involving the alkanes,alkenes,alkynes,alcohols,esters,aldehydes,acids,ketones, ethers,acyl chloride,heterocycles,amide and other substances. In total 43 compounds were identified in the SOB vola- tile oil extracted by the conventional steam distillation,accounting for 88.20% of the total oil amount,which was related to the alkanes,alkenes,alkynes,alcohols,esters,aldehydes,acids,ethers,ketones,heterocycles,amides and other substances. The monosaccharide composition analysis showed that the SOB polysaccharide was composed of 5 kinds of monosaccharides. Conclusion: Among the identified compounds,only 9 compounds existed in the SOB volatile oils extracted by two different Methods:,indicating that the combined use of the two different extraction Methods: may be more powerful for comprehensive analysis of the chemical constituents of SOB volatile oil.
