Objective To investigate the morphological difference of spinal single vertebral tuberculosis and metastasis by means of CT.Methods CT features of 16 cases of single vertebral tuberculosis and 17 cases of single vertebral metastasis which were proven by clinically and/or pathology, were retrospectively analyzed,and then the CT differential criteria of the two categories of diseases was recommended.Results The reliable CT findings for vertebral tuberculosis were as follows: involvement of anteriomedial potion of vatebral body,presence of sequstra in lesion ,marginal sclerosis in the edge of lesion,calcification within paravertebralmass or abscesses ,only edge enhancement of more of paravertebralmass.Metastasis was characterized by involvement of posteriomedial portion of vertebral bone,absence of sequestra within lesion ,no calcification within paravertebralmass.Both of them had normal intervertebral disc.Conclusion The different CT features of the single vertebral tuberculosis and metastasis are helpful in differerntiating diagnosis ,the morphological change of intervertebral discs is not helpful in differerntiating diagnosis .

Bile reflux is not only related to diseases such as gastritis,esophagitis,pharyngitis,chorditis,bronchitis and pneumonia,but also related to residual gastric ulcer,residual gastric cancer,intestinal metaplasia,dysplasia and carcinogenesis. Risk factors related to bile reflux include various operation modes, various anastomosis methods, gallbladder stone, cholecystectomy and various non-operative factors such as age, gender, allergy, mental and psychological factors,congenital factors. This article reviewed the advances in study on risk factors related to bile reflux.

Objective To discuss the strategies of lower complications of LC in the initial stage. Methods The clinical data of 168 patients,from Sep. 2008 to May. 2010 ,treated with laparoscopic cholectectomy were retrospectively analyzed. Results LC was performed in all patients(100%). None of the series had intra-abdominal bleeding,biliary tract injury and no other serious complications were observed. Conclusion Through correct perioperative management and meticulous operation, LC was safe and complications lower in the initial stage.

Objective To investigate the effects of valsartan on the expression of acyl-coenzyme A: cholesterol acyltransferase-1(ACAT-1) and peroxisome proliferator activated receptor-gamma(PPAR-?) in atherosclerotic plaques on rabbit aortic wall.Methods Twenty-four male Japanese white rabbits were randomly assigned into three groups(8 each): control group,valsartan group and high cholesterol feeding group.All rabbits were fed according to the experimental protocol for 12 weeks.Blood samples were taken from vein for measurement of serum lipids.The ratio of intima/media thickness of the aorta was measured.ACAT-1 mRNA/protein and PPAR-? mRNA/protein were determined by reverse transcription polymerase chain reaction(RT-PCR) and Western blotting,respectively.Results After 12 weeks,the levels of serum total cholesterol(TC),triglyeride(TG) and low density lipoprotein-cholesterol(LDL-C) in valsartan group and cholesterol group were significantly higher than those in control group(P0.05).The intima thickness and the ratio of intima/media in carotid arteries in cholesterol group were significantly higher than those in control group and valsartan group(P

Objective To evaluate the relationship between long-term survival rate and protection to marrow and lymphoid tissues in the pelvis with hypoxia radiotherapy for uterine cervical carcinoma. Methods 113 patients, confirmed as having carcinoma of uterine cervix by pathology, were randomly divided by the envelope method into two groups: hypoxia radiotherapy group(HRG,57 patients) and conventional radiotherapy group (CRG,56 patients). HRG was given by sustained inhaling hypoxia gas (oxygen physical volume=0.105) for two minutes before the start of radiotherapy till the end of radiotherapy of each field and then repeated for the other field in the same way. The duration of irradiation to each field was less than five minutes. CRG was given with conventional radiotherapy. The irradiation dose in the midpelvical plane was 20-50Gy depending on the different stages of cervical carcinomatous lesion. The dose of four-divided-field in the parametria was 15-34Gy.The dose at point A of intracavitary therapy was 15-35Gy. Results The decreased value of peripheral blood white cells after treatment was (1.36?1.27)?109/L in HRG and (2.97?1.19)?109/L in CRG(P

Objective To study the relationship between QT interval and the components of metabolic syndrome in adult Chinese population.Methods Totally 975 adults(494 men and 481 women)aged 41~53 from the study cohort of Fetal Origin of Adult Disease(FOAD)were recruited in the study for epidemiologic examinations,involving anthropometry and measurements of blood pressure,fasting and 2hr plasma levels of glucose and insulin and serum levels of lipid.A standard 12-lead ECG was recorded and the corrected QT(QTc)was calculated accordingly by Bazett formula.HOMA-IR index was calculated for estimating individual insulin resistance.Metabolic syndrome(MS)was diagnosed according to the definition issued by the International Diabetes Federation(IDF)in 2005.Results The prolonged QT interval was found in 262 of the 975 cases(26.9%),and the rates of prolonged QT interval being 21.6% and 32.6% in men and women respectively(P=0.0001).The prevalences of MS,IR,central obesity,IFG,higher serum level of triglyceride(TG)and lower serum level of high-density lipoprotein cholesterol(HDL-C)were 19.7%,19.5%,42.5%,34.3%,26.3%,34.6% and 31.1% in this mid-aged population respectively.The prolonged QT interval was significantly associated with MS,IR,IFG,higher serum level of triglyceride(TG)and certral obesity respectively(P

Objective To discuss the treatment of cranialfacial fibrous dysplasia. Methods The treatment of 10 cases of cranialfacial fibrous dysplasia was analyzed. Results The cosmetic deformity was corrected in all the cases.No new symptom of nervous system occurred. Conclusion It is important to carry out the correct surgical plan according to patients' age,location,mono-or poly-ostotic form of fibrous dysplasia,presence or absence of functional limitations,and aesthetic problem.

Experiment teaching is a major part of medical education,which plays an important role in cultivating science thought and creative ability.In order to further deepen functional experiment teaching reform,this paper generalized the achievements and the problems in function experiment centre operation.It also proposed the new trend in the next step of reform.

Objective To evaluate the effectiveness and safety of dexmedetomidine for the sedation of the patients after coronary artery bypass grafting (CABG).Methods The selective 96 CABG patients,ASA Ⅱor Ⅲ,aged 36 to 68 years old,58 males and 38 females,were randomly divided into 2 groups (n =48):dexmedetomidine group (group A) and midazolam group (group B).Group A patients received Dexmedetomidine (1.0 μg/kg)over 10 min,followed by 0.2-0.7 μg · kg-1 · h-1 to maintain sedation,whereas the other group patients received midazolam (0.05 mg/kg) over 10 min,followed by 0.02-0.10 mg · kg-1 · h-1 to maintain sedation.Two groups of patients stopped using drug when they were fit off-line and extubation.Observe the percentage of time within target sedative scope (Riker range 3-4),the changes of vital signs before and after treatment,the prevalence of delirium,the awakening time,the duration of mechanical ventilation,ICU length of stay,the adverse events of blood pressure and heart rate.Results There were no significant difference in the percentage of time within target sedative scope between two groups (75.5％ for dexmedetomidine group vs 74.6％ for midazolam group,P ＞ 0.05).Compared to midazolam group,the Dexmedetomidine group has a shorter awakening time [(14.0 ± 6.2) min for dexmedetomidine group vs (50.4 ± 12.8) min for midazolam group,P ＜ 0.05] and duration of mechanical ventilation,and also the prevalence of delirium was lower(15.3％ for dexmedetomidine group vs 34.6％ for midazolam group,P ＜0.05).ICU length of stay was similar.Dexmedetomidine-treated patients were more likely to develop bradcardia,with a non significant increase in the proportion requiring treatment,but had a lower likelihood of tachycardia or hypertension requiring treatment.Conclusion Dexmedetomidine is safe and effective in patients after CABG surgery.
