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 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.

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.

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.

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.
