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.

Hepatitis B virus(HBV)will become reactive in non-active HBsAg carriers when they are in the immunosuppression status,which is often caused by cytotoxic drugs in chemotherapy or immunosuppressants.Liver damage will be induced in such patients and even liver failure in some patients.Nucleoside analogues could be used in early phase as prophylaxis for reactivation of hepatitis B in immunosuppression and to improve clinical prognosis.

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

Nitrogen mustard encapsulated with liposomes was administered to the rabbits with acute experimental serum sickness(AESS). Then the serum levels of anti-BSA antibodies and circulating; immune complex(CIC), CH50, and WBC count were determined. The ACPase activity of spleen macrophages was measured. And the sections of renal tissues, after HE-stained, were studied for the accumulation of CIC and the pathological changes. It was found that liposome-encapsulated nitrogen mustard can increase the macrophage activity and in turn aggravate the renal damages of AESS rabbits.The results suggest that the renal damages of AESS rabbits can immunopatholo-gically be attributed to the increased activity of macrophages.

PI3K/Akt pathway is a biological signal transduction pathway activated by phosphatidylinositol 3-kinase (PI3K).It plays a key role in cell proliferation,cell-cycle regulation,apoptosis initiation,and angiogenesis.In addition,the PI3K/Akt pathway is closely associated with the protection mechanisms of central nervous system damage.In-depth study of PI3K/Akt,downstream molecules and their regulation mechanisms,can provide some new ideas and methods for the treatment of brain injury.

Objective To investigate the relationship between absent end-diastolic velocity (AEDV) in umbilical artery and perinatal outcome,and to explore the effect of termination time of pregnancy on perinatal outcome. Methods Data of thirty five pregnant women with AEDV admitted into Beijing Obstetrics and Gynecology Hospital from January 2008 to December 2009 were retrospectively analyzed.According to gestational age and treatment,they were divided into four groups.Group 1:AEDV was identified before 28 weeks without treatment (n=5); Group 2:AEDV was found before 28 weeks,and then was treated (n=13); Group 3:AEDV was found after 28 weeks,and was not treated (n=11); Group 4:AEDV was found after 28 weeks,and then was treated (n=6). Except for three patients in Group 2,all patients had complications.Data were presented by frequency,rate or mean±SD. Results Among the 35 patients,19 (54.3％) delivered and 23 living children were born.When AEDV was found,the gestational age was less than 28 weeks and the mean gestational age was (22.8 ± 2.2) weeks in Group 1,(24.2 ± 2.0) weeks in Group 2,however,the gestational age was over 28 weeks and the mean value was (30.9± 2.8) weeks in Group 3 and (29.5±0.8) weeks in Group 4.Treatment was given to women in Groups 2 and 4,but not in Group 1 and 3.In Group 1,one patient complicated with twin-twin transfusion syndrome; one with hemolysis,elevated liver enzymes and low platelet syndrome and placental abruption; three recovered after two weeks and babies survived.In Group 2,the termination time was (31.4 ± 5.5)gestational weeks and the duration of treatment was (10.7± 5.5) days.AEDV of six patients were not improved after treatment,among which five accepted induced abortion,one had preterm delivery.The rest six women underwent cesarean section and one term delivered.Babies survived except for one preterm neonate and one lost in follow-up.In Group 3,the termination time was (31.2 ± 2.9)gestational weeks.Five patients accepted artificial abortion for severe complications of mother or babies; the other six patients accepted cesarean section,among which one complicated with placental abruption and baby died.The rest five babies survived.In Group 4,the pregnancies were terminated at an average of (32.8±2.9) gestational weeks and the duration of treatment was (10.8±6.7) days.Two accepted induction after treatment and four recovered to normal after treatment and accepted cesarean section with four wellbeing babies. Conclusions Perinatal outcomes of patients with AEDV complicated with severe complications after active treatment might relate to the termination time.Some patients with AEDV without severe complications might recover spontaneously with good prognosis.

Objective To explore the effective method at different times of the early treatment of acupuncture and rehabilitation therapy on motor dysfunction after cerebral infarction. Methods According the course of disease ,97 patients with motor dysfunction after cerebral infarction were divided into two groups:the observation group (48h after onset) and the control group(48h after stable vital signs). The two groups were given to the same acupuncture and rehabilitation treatment at 48h after onset and stable vital signs using 48h after respectively in the premise of conventional treatment. The treatment outcomes after three courses were compared,and each course was 7 ～ 10d. Results The Fugl-Meyer motor function score and FMA motor dysfunction assessed in the observation group were better than that in the control group (P <0.01, P < 0.05 ). Conclusion The acupuncture and rehabilitation treatment for motor dysfunction after cerebral infarction at 48 h after onset was better than that at 48h after stable vital signs.
