It is common in bacterial genomes of the integration of prophages. As an important participant of the vital movement of their hosts, prophages affect closely the biological properties of the hosts. Therefore, if we want to comprehend a bacterial genome fully, it is essential to recognize and understand accurately prophages in it. This article is a compendious review about the classification, distribution, identification, evolution of prophages and the interaction with their hosts.

ObjectiveTo establish a surface location method and acupuncture manipulation standard by dissecting the local structure of rat point Renying(ST9)and make a validation through the hypotensive effect of acupuncture.MethodA Wistar rat was sacrificed and fixed by cryogenic freezing. According the anatomical characteristics of human point Renying, cervical point Renying region was dissected layer by layer, and the common carotid artery, the internal carotid artery and the external carotid artery were bluntly separated. Location and measurement were made using vernier calipers and digital photographs were taken. Body surface location and acupuncture point depth were statistically analyzed to establish acupuncture manipulation standards. Point Renying and a non-acupoint were separately acupunctured to treat rat spontaneous hypertension. The changing tendency of blood pressure was statistically analyzed after four weeks.ResultAccording to the 95% reference value range, the surface location of rat point Renying was determined to be (8±0.3)mm below a line connecting bilateral mandibular angles and (5.5±0.4)mm lateral to the anterior midline, one on each side. Acupuncture manipulation standards were perpendicular insertion (5.5±0.4)mm and cautious lifting and thrusting to avoid injuring the artery. Acupuncture at point Renying had a marked hypotensive effect as compared with a non-acupoint (P<0.05).ConclusionThe surface location of rat point Renying is reliable and can be applied to animal experimental study.

BACKGROUND:Bone marrow mesenchymal stem cells have beneficial effects on the treatment of various diseases. Mitochondria transfer is newly proposed and its specific mechanisms of action and control factors remain unclear.
OBJECTIVE:To review the studies about stem cells and mitochondrial transfer, then to discuss its value on clinical.
METHODS:The PubMed, VIP and Wanfang databases were searched for related articles concerning stem cells and mitochondrial transfer. Key words were“stem cell, embryonic stem cell, progenitor cell, mitochondria”in Chinese and“Stem cell[s], Mother cell[s], Progenitor cell[s], Colony-Forming Unit[s], Colony Forming Unit[s], Mitochondria[l] transfer”in English. Thirteen articles were found initial y, and using the citation tracking method, final y 42 articles were determined. RESULTS AND CONCLUSION:Studies have shown that mitochondrial transfer from bone marrow mesenchymal stem cells is associated with rescue of aerobic respiration and restoration of mitochondrial function in the injured somatic cells. Bone marrow mesenchymal stem cells and recipient cells form tunneling nanotubes for mitochondrial transfer. Movement of mitochondria between cells is regulated and directed by Miro1. The successful transfer of mitochondria may be accompanied with the clearance of damaged mitochondria. The rescue of mitochondrial function in early stages may provide a valuable therapeutic strategy for various diseases include acute lung injury.

Objective To search for evidence of diagnosis of pulmonary embolism for guiding clinical practice.Methods We searched PubMed(1970~2005-10)and CBM(1992~2005-10)in Oct.2005 to identify system reviews(SR)and cross-sectional study(CSS)about the diagnosis of pulmonary embolism.Results Sixteen SR and 9 CSS were identified in PubMed,none in CBM.Pulmonary arteriography was the gold standard in the diagnosis of pulmonary embolism.Our result showed that computed tomography,ventilation-perfusion scanning and doppler ultrasound were useful in the diagnosis of pulmonary embolism combind with clinical judgment.Multidetector CT might be another gold standard in the diagnosis of pulmonary embolism.A negative result on quantitative rapid ELISA of D-dimer could exclude the diagnosis of pulmonary embolism.Conclusion Diagnostic tests combind with clinical judgment are useful for diagnosing or excluding pulmonary embolism.

OBJECTIVE　To study the pharmacokinetics of bifonazole in healthy human,in order to evaluate the safety of bifonazole.METHODS　8 healthy volunteers were given single dose of 300 mg bifonazole solution and cream preparation respectively in a cross-over design.Blood samples were collected at the designed time,and the concentrations of bifonazole in plasma were determined by means of GC-MS(SIM) quantitative method.The pharmacokinetic parameters were calculated with the 3P87 software.RESULTS　The plasma concentration-time curves of the two preparations were fitted to two-compartment open model.The tmax of the solution and cream preparations were 2.91 h and 5.62 h,cmax 713.46 ng.mL-1 and 410.70 ng*mL-1,respectively.The cream preparations absorption,distribution and clearance was a little slower than that of the solution preparation.However,no significant difference in their AUC.CONCLUSION　Bifonazole is a safe drug,and clinical use of the solution and cream preparation in turn is suggested to improve its therapeutic efficacy.

Objective To study the dynamic changes of soluble intracellular adhesion molecule-1 (sICAM-1), and to assess its role in the pathogenesis of hemorrhagic fever(HFRS) with renal syndrome. Methods A total of 30 patients with HFRS(case group) and 20 healthy subjects (control group) from Worker Hospital of Finance & Commerce of Qiqihar city were included in the study during 2006 - 2007. Double-antibody sandwich ELISA method was used to measure the level of sICAM-1 in serum samples. Results The serum levels of sICAM-1 in patients with HFRS in early stage, critical stage, convalescent stage were(47.56±6.51), (94.23±15.36), (54.19±8.42)ng/L,respectively. The serum level of sICAM-1 in control group was (22.63±3.40)ng/L. The above values were compared between any two groups, differences were statistically significant (all P < 0.01). The serum level of urea nitrogen in patients with HFRS in early stage, critical stage, convalescent stage were (5.16±0.12), (33.84±9.24),(8.20±1.30)mmol/L, respectively. The serum level of urea nitrogen in control group was (4.20±0.56)mmol/L.The above value were compared between any two groups, the differences were statistically significant (all P< 0.01). Conclusions sICAM-1 is involved in the pathogenesis of HFRS as protective factors. Cellular immune playes an important role in the pathogenesis of HFRS.
