Objective To study different e mbolization methods in various aneurys ms with metallic coils. Methods In 6 spherical aneurysms, the e mbolization was p erformed with coils in their bodies, discontinuing the total or part of the bloo d supply to the corresponding viscera. While in 6 diverticulum aneurysms, the em bolization with coils was conducted in their bodies only, maintaining the blood supply of the corresponding viscera. For some pseudoaneurysms, both afferent and efferent arteries were embolized and collateral arterial supplies were prevente d. Results All 19 cases 20 aneurysms, of aneurysms were success fully embolized. Among 8 cases of pseudoaneurysms, bleeding had been stopped in 7 cases. Putting coils in the b odies of aneurysms or embolizing both afferent and efferent arteries improved su ccessful rate. Conclusion Embolizing aneurysms with metallic co ils is an efficient, reliable, and simple interventional method for stopping bleeding.

Objective To investigate related factors of gastrointestinal bleeding in elderly advanced cancer hospice inpatients , in order to facilitate better control. Methods A retrospective investigation of the clinical data of the elderly advanced cancer hospice inpatients was done , 85 cases with gastrointestinal bleeding (experimentalgroup) were compared with 294 cases with non-gastrointestinal bleeding cases (control group). Results Multivariate logistic stepwise regression analysis showed:HP infection [odds ratios (OR) = 3.241,95% confidence interval (CI) 1.792~5.863], non-steroidal anti-inflammatory drugs (OR=3.080,95%CI 1.725~5.497), long-term heart and lung disease (OR=2.323,95%CI 1.315~4.105), stress (OR=1.858,95%CI 1.054 ~ 3.274), albumin (OR =0.760,95%CI 0.679~0.851), enteral nutrition (OR=0.499,95%CI 0.679~0.851) on gastrointestinal bleeding in elderly advanced cancer hospice inpatients were significant (P<0.05). Conclusions We should strengthen the surveillance of elderly advanced cancer hospice inpatients with gastrointestinal bleeding , to improve the quality of life,and according to the risk factors,the early diagnosis and treatment must be regarded.

Ultrasonic sensors are optimal to the guidance system for the blind.The previous ultrasonic guidance systems acquire the position information of obstacles,and transform it into audio signal or tactile vibration.The system developed in this paper,utilizing programmable gain technique and digital potentiometer,acquires the power of reflected ultrasonic as additional information,and informs the blind with modulated audio signal.In this paper,the studies on programmable gain is described detailed including the hardware structure,the software design and information post processing.

Lives are maintained by enough oxygen.Blood oxygen saturation is one of the important parameters which reflects oxygen concentration in blood.The accurate monitoring of blood oxygen saturation is very important to both physiological research and medical application.At present,dual-wavelength method is widely adopted in noninvasive detection of blood oxygen saturation.Therefore,accurate recognition of peak-to-peak value of pulse waveform is a key process in monitoring blood oxygen saturation.In the paper,LMS self-adaptive arithmetic is applied to processing pulse waveform signal.The ratio of corrective detection is improved by the method.

Objective To investigate the promoter methylation status and the transcription level of BLU in bladder carcinoma and their significance.Methods The methylation status of promoter and the transcription level of BLU were examined by methylation specific PCR(MSP) and RT-PCR in bladder cancer tissues from 54 patients,adjacent normal tissues from 45 cases and normal bladder tissues from 3 noncancerous patients.Results ① 31.5%(17/54) bladder cancer tissues showed BLU hypermethylation;neither the paired adjacent normal tissues nor the three normal bladder tissues showed BLU hypermethylation.② There was no significant correlation between the methylation status and the clinical pathological parameters in bladder cancer.③ The expression of BLU was absent in 42.2%(19/45) of bladder carcinoma from cystectomy.④ Loss of BLU expression was associated with the stage and grade of the tumor(P

Objective To investigate the methylation status of the promoter of RASSF1A gene in the tissues of bladder cancer and renal carcinoma and its role in tumorigenesis. Methods Methylation specific PCR (MSP) was used to examine the methylation status of RASSF1A in bladder cancer and renal carcinoma.The specimen included 45 cases of bladder cancer tissues and paired adjacent normal tissues from cystectomy,9 cases of bladder cancer tissues from microresection,3 cases of normal bladder tissues from people without tumor,12 cases of renal carcinoma tissues and paired adjacent normal tissues. Results 30 of 54(55.6%)bladder cancer tissues showed RASSF1A gene aberrant methylation.Of which,26 of 45 ( 57.8 %) bladder cancer tissues from cystectomy showed aberrant methylation,while one of the paired normal tissues showed gene methylation,4 of 9 (44.4%) bladder cancer tissues from microresection showed gene methylation.Eight of 12(66.7%)renal carcinoma tissues showed aberrant methylation,while none of the paired adjacent normal tissues showed gene methylation.None of the three normal bladder tissues showed aberrant methylation.There was no significant correlation between the methylation status and the clinical pathological parameters in bladder cancer tissues from cystectomy,though there was a trend that more frequent methylation was detected in higher stage bladder cancer. Conclusions Hypermethylation of RASSF1A gene in bladder cancer and renal carcinoma suggeste its possible role in the tumorigenesis of both tumors.

Deep vein thrombosis is a common complication after orthopedic, gynecological, and obstetric operations. However, instances of this complication after oral and maxillofacial surgeries have been rarely reported. We report a case with odontogenic keratocyst in the jaw that gained left lower extremity venous thrombosis after operation, and discuss the risk factors and prevention of lower extremity venous thrombosis through literature review.

BACKGROUND:There are more literature reports about the floating shoulder injury in recent years, but there stil have obvious controversies about the treatment of the floating shoulder injury. Whether choose the conservative treatment or operative treatment is an important issue in face of every clinician. OBJECTIVE:To review the clinical features and present treatment situation of the floating shoulder injury. METHODS: A computer-based online search was performed in the PubMed and the China National Knowledge Infrastructure database for the clinical research papers on the treatment methods of the floating shoulder injury from January 1975 to August 2015. The key words were floating shoulder injury, diagnose, treatment method. The articles published earlier and repetitive researches were excluded. Finaly, 33 articles were included for further analysis. RESULTS AND CONCLUSION:(1) Floating shoulder injury is a kind of severe shoulder injury which is caused by high energy and violence. It is often complicated with severe systemic injury, which should be paid more attention in clinic. (2) The treatment of floating shoulder injury has been controversial, and there is no standard treatment guideline. Conservative treatment and operative treatment can get good outcomes. There are less reports about conservative treatment of the floating shoulder injury in recent years. The outcome of operative treatment may better than conservative treatment. (3) Conservative or simple clavicle fixation can be used for fractures without displacement or with smal displacement. Obviously displaced fractures can be treated with simple clavicle fixation or double fixation of clavicle and scapula, which may have good repair effects.

The clinical thoughts of interns have some features such as insufficiency of initiative and enthusiasm and the absence of systemic. It is necessary to develop their good habits of active and diligent thinking as well as comprehensive thinking ability. Clinical teaching rounds, small lectures,discussion of complicated cases and interactive teaching are the specific measures for our medical interns to improve their ability of clinical thoughts effectifally.
