Objective To discuss the clinical application of preoperative transcatheter arterial chemoembolization (TACE) in treating squamous cell carcinoma of tongue. Methods A total of 26 patients with pathologically proved squamous cell carcinoma of tongue were enrolled in this study. Using Seldinger technique, lingual artery angiography and TACE were carried out in all patients. Radical resection of tongue cancer was performed in 2-3 weeks after TACE. Results Super-selective catheterization and TACE was successfully accomplished in all patients. After TACE the tumor size was significantly decreased in all patients. During the operation, clear lesion's border was observed, and the amount of blood loss was less than usual. Conclusion For the treatment of squamous cell carcinoma of tongue, preoperative superselective TACE is safe and effective;it can increase the opportunity of surgical resection, reduce the surgical damage, and improve the quality of life as well as the survival rate.

Objective To investigate the effect of cyclopentolate cycloplegic on the refraction measurement in adult guinea pigs. Design Experimental study.Participants 24 eyes of 12(10 weeks) adult guinea pigs.Methods 12 animals were randomly examined thrice by streak retinoscopy pre and post mydriasis.1%cyclopentolate hydrochloride was topically administrated to the eye every five minutes for three times.Main Outcome Measures The eye refraction of guinea pigs included the scope,cylinder and the equivalent power.Results The average refraction of guinea pigs in pre-mydriasis and post-mydriasis were 1.92?0.79 D and 2.08?0.79 D respectively. The average refraction that included the scope,cylinder and the equivalent power all showed no significant difference between pre and post mydriasis.The effect of mydriasis and measure time points on the refraction that included the scope,cylinder and the equivalent scope showed no significant difference either.Conclusions The effect of 1%cyclopentolate cycloplegic on adult guinea pigs in refraction is limited.The refraction of adult guinea pig can be measured naturally without cyclopentolate cycloplegic administrated.

Objective: To study the relationship between explicit/implicit self-esteem and mental health. Methods: 49 college students (including 26 male and 23 female, mean age 22) completed Rosenberg Self-esteem Scale and SCL-90. Their implicit self-esteem was measured by Implicit Association Test (IAT). Results: The results indicated a moderate to strong correlation between explicit self-esteem and mental health level. Yet the implicit indicator show insignificant influence on mental health. Conclusion: The study tends to support the hypothesis that implicit self-esteem is a independent structure from explicit self-esteem

Objective To investigate the usage of antibiotics in pediatrics patients in Changchun,and detect the bacterial drug resistance of main pathogens for direction of the appropriate clinical choice of drug antibiotics.Methods A total of 900 cases of infectious patients were retrospectively investigated in antibiotic usage in the ⅢA hospital in Changchun from January 2003 to November 2005 and the data were statistics analyzed.The bacterium were isolated from all kinds of specimen of children in hospital patients from December 2004 to November 2005,according to the method of "Clinical Medicine Test Handbook".All bacterial isolated from bacterial susceptibility tes-(ting) was done with Kirby-Bauey method.Tests were performed according to the guidelines of National Committee for Clinical Laboratory Standards(NCCLS)(2004).Results Antibiotics were administered in all of the cases.Four categories and 11 kinds of antibiotics were used.Usage of the first six antibiotics were as followed: ceftezole(22.3%),cefoperazone-sulbactam(21.6%),amoxicillin clavulanic acid((19.6%),)penicilin(17.2%),azithromycin(16.40%),oxacillin(10.1%).The rate of antibiotic use was 60.6% for solo use,70.7% for bigeminy use,81.7% for intravenously guttae,18.3% for peroral administration.Eight hundred and eighteen strains of pathogens were isolated.Gram-positive coccus,gram-negative accounted for 48.0% and 52.0%,respectively.All bacterium isolated showed a high resistance against penicillins and cephalosporins.Drug resistance rate of Gram-positive bacteria to penicillin was more than 50.0%,CNS,S.aureus,E.faecalis and S.pneumonic to erythromycin and cphalosporins was over 71.4% and 35.7%.The antibiotic remaining the most active against Gram-positive bacteria was vancomycin.The drug resistance rate against imipenem and ciprofloxacin were lower than(25.0%.)The antibiotic resistance rate of Gram-negative bacteria to ampicillin,cephalosporins and aztreonam were more than 83.0%,(40.0%) and 32.0%,to piperacillin and amoxicillin-clavulanic acid were morn than 68.9%,except P.aeruginosa(33.3%).The susceptibility of Gram-negative bacteria was imipenem(

Objective To investigate the clinical efficacy of Jiawei Guizhi Fuling Decoction combined with mifepristone on uterine fibroids and the changes of serum sex hormone levels in patients after treatment.MethodsForty-two patients were randomly divided into three groups: control group (42 cases) and control group (41 cases).The rats were treated with Guizhi Fuling Decoction plus mifepristone combination for three months.The control group was given only monotherapy with normal mifepristone tablets.The time of treatment was consistent with that of the study group.The levels of serum sex hormones were measured quantitatively before and after treatment.By comparing the therapeutic effect of the patients in different experimental groups and the levels of hormone Differences in evaluation between groups.ResultsThe total effective rate of 92.9% in the study group was significantly better than that in the control group (73.8%).The difference between the two groups was statistically significant (P<0.01).After treatment, the study group and the control group Uterine / tumor volume was significantly reduced, the difference was significantly different (P<0.01), compared between the two groups after treatment of uterine / tumor volume, the study group than the control group, the volume was significantly reduced, the difference was statistically significant (P<0.05).Serum levels of sex hormones: Serum levels of E2 and P were significantly lower in the study group than in the control group (P<0.05).Before and after treatment, the levels of serum E2 and P were lower in the two groups than before treatment (P<0.05).ConclusionJiawei Guizhi Fuling Decoction combined with mifepristone has a better effect on the treatment of uterine fibroids with mifepristone monotherapy, which significantly reduces the level of serum sex hormones and promotes the reduction of uterine / tumor volume after administration.It is worthy of promotion the combination of traditional Chinese and Western medicine conservative treatment of uterine fibroids means.

OBJECTIVETo verify the optimal cut-off points for overweight and obesity in Chinese adults based on the relationship of baseline body mass index (BMI) to all-cause mortality, and incidence of cardiovascular diseases from pooled data of Chinese cohorts.

METHODSThe prospective study data of existing cohort studies in China were collected, and the age-adjusted all-cause mortality stratified by BMI were estimated. The similar analysis was repeated after excluding deaths within the first three years of follow-up and after excluding smokers. The incidence of age-adjusted coronary heart disease (CHD) and stroke stratified by BMI were also analyzed. Multiple Cox regression coefficients of BMI for the incidence of CHD and stroke after controlling other risk factors were pooled utilizing the methods of weighting by inverse of variance to reveal whether BMI had independent effect and its strength on the incidence of CHD and stroke.

RESULTSThe data of 4 cohorts including 76,227 persons, with 745,346 person-years of follow-up were collected and analyzed. The age-adjusted all-cause mortality stratified by BMI showed a U-shaped curve, even after excluding deaths within the first three years of follow-up and excluding smokers. Age-adjusted all-cause mortality increased when BMI was lower than 18.5 and higher than 28. The incidence of CHD and stroke, especially ishemic stroke increased with increasing BMI, this was consistent with parallel increasing of risk factors. Cox regression analysis showed that BMI was an independent risk factor for both CHD and stroke. Each amount of 2 kg/m2 increase in baseline BMI might cause 15.4%, 6.1% and 18.8% increase in relative risk of CHD, total stroke and ischemic stroke. Reduction of BMI to under 24 might prevent the incidence of CHD by 11% and that of stroke by 15% for men, and 22% of both diseases for women.

CONCLUSIONBMI < or = 18.5, 24-27.9 and > or = 28 (kg/m2) is the appropriate cut-off points for underweight, overweight and obesity in Chinese adults.
