Aim To investigate the effects of isoliquiritigenin(ISL) on cognition dysfunction and brain energy metabolism following repeated cerebral ischemia-reperfusion in mice.Methods Mouse models of learning and memory deficits were made by repeated occlusion of bilateral common carotid arteries and reperfusion. Step-down test and Y-maze task were used to examine the learning and memory abilities of mice. The brain energy state was analyzed by reversed-phase high performance liquid chromatogra phy. Results ISL 10, 20 and 40 mg?kg -1 ig reduced the n umber of errors and extended the latency of memory in step-down test, decreased the number of cumulated stimulation and increased the number of right choices i n Y-maze task. ISL(10, 20, 40 mg?kg -1) increased the levels of ATP, ener gy charge (EC) and total adenine nucleotides(TAN) in a dose-dependent manner. Conclusion The results suggest that ISL improves cognition dysfun ction induced by repeated cerebral ischemia-reperfusion in mice, which may be r elated to the improvement of brain energy metabolism.

Objective To study the effect of liver transplantation using right liver lobe Ⅴ and Ⅷ segments with middle hepatic vein(MHV) and without main MHV on the regeneration of liver transplantation. Methods 25 pair of donors and receptors of liver transplantation were divided in to two groups:with M HV group (group A, n= 14) and without main MHV (group B, n=11). The volumes of Ⅴ and Ⅷ segments of liver were measured in donors presurgicaUy,half month and 3 month in receptors postsurgically, the rates of regeneration of the Ⅴ and Ⅷ segment were calculated half month and 3 months postsurgically and compared between two groups. Results In group A,the regenerate rates of the Ⅴ,Ⅷ segment were 0.360±0.043 and 0.853±0.059 half month after surgery,0.253±0.043 and 0.708±0.059 three months after surgery respectively. In group B, the regenerate rates of the Ⅴ,Ⅷ segment were 0.306±0.049 and 0.815±0.066, respectively half month after graft, 0.161±0.049 and 0.627±0.066, respectively three months after surgery. There were no statistically significant differences in regenerate rates of the Ⅴ, Ⅷ segment of graft be-tween the two groups (P= 0.685 ,P>0.05 and P= 0.738, P>0.05). Conclusion The right lobe living donor liver transplantation, maintaining the MHV or reconstruct MHV tributaries without MHV has similar effects on the regeneration of Ⅴ,Ⅷ segment of graft.

To explore the clinical characteristic and intervention strategies for pregnancy complicated with heart failure. The clinical data of 67 pregnant women with heart failure during January 1998 to December 2010 were collected and analyzed.The rate of heart failure in pregnancy with heart diseases was 31% (67/216).The causes of pregnancy complicated with heart failure were peripartum cardiomyopathy ( n =33,49% ) and hypertensive disorder complicating with pregnancy heart disease( n =28,42% ).Heart failure in pregnancy appeared at an average of (36.0 ± 2.7 ) weeks.The average terminating time of pregnant women with heart failure was ( 36.5 ± 2.1 ) weeks.Cesarean section was the main safe choice of delivery for pregnant women with heart failure.The average weight of newborns for pregnant women with heart failure was(2517 ±541 )g.The rate of neonatal asphyxia was 22% (11/50).Strengthening routine antenatal examination and treating pregnant complications timely can prevent and reduce the incidence of heart failure.

OBJECTIVETo compare the clinical efficacy difference between electroacupuncture (EA) at qijie area combined with spine balance-regulating massage and medication for posterior circulation ischemia (PCI).
METHODSOne hundred cases of PCI were randomly divided into a treatment group (50 cases) and a medication group (50 cases). The treatment group was treated with EA at Baihui (GV 20), Sishencong (EX-HN 1), Fengchi (GB 20), Shenshu (BL 23), Danzhong (CV 17), etc. in qijie area combined with spine muscle-relieving massage and comprehensive chiropractic. The medication group was treated with oral administration of nimodipine (30 mg per time, three treatments per day) and vinpocetine injection with 500 mL of glucose injection or intravenous drip of 500 mL 0.9% sodium chloride injection, once a day. Ten treatments were taken as one course in both groups, and two courses were given. The symptom score, mean resistance index (RI) of vertebral artery (VA) and basilar artery (BA), mean velocity of blood flow (Vm) and comprehensive clinical efficacy were compared before and after treatment in two groups.
RESULTSThe cured and markedly effective rate was 79.6% (39/49) in the treatment group, which was superior to 54.7% (23/42) in the medication group (P<0.05). The symptom score was both significantly improved after treatment in two groups (both P<0.05), which was more obvious in the treatment group (P<0.05). The RI of VA and BA, Vm of VA and BA were significantly improved after treatment in two groups (all P<0.05), which were more obvious in the treatment group (all P<0.05).
CONCLUSIONThe electroacupuncture combined with spine balance-regulating massage has superior effect on improving mean velocity of blood flow and resistance index of vertebral artery and basilar artery as well as symptom score to medication, and is believed to be a safe and effective treatment for posterior circulation ischemia.

OBJECTIVETo investigate the characteristics, diagnosis, and treatment of ovotesticular disorder of sex development (OT-DSD).
METHODSWe retrospectively analyzed 2 cases of OT-DSD treated in our hospital. The patients were 19 and 15 years old, respectively, and both received systematic physical examination and examinations of the karyotype, sex hormone, adrenocorticotropic hormone (ACTH), color Doppler ultrasonography, urethrocystoscopy, and human chorionic gonadotropin (HCG) test. Under the laparoscope, we performed surgical gonad exploration, gonadectomy, and vulvar orthopedics. Intraoperative exploration and pathology confirmed true hermaphroditism in both cases, with sex selection as female. One underwent laparoscopic resection of the ovotestis, and the other removal of the testis with the ovarian tissue reserved.
RESULTSThe patients were followed up for 12 months postoperatively, which found no abnormality in either the vulvas or the genital glands.
CONCLUSIONSurgical exploration of the gonad is the only method for the diagnosis of OT-DSD and sex selection is the key to treatment. Laparoscopic surgical exploration of the gonad and vulvar orthopedics are the first treatment options.

OBJECTIVETo evaluate the therapeutic effect on pain in the dressing change after perianal abscess surgery treated with warm suspending moxibustion at Changqiang (GV 1).
METHODSOne hundred and sixty patients were randomized into a moxibustion group and a far-infrared therapy group, 80 cases in each one. In the moxibustion group, the warm suspending moxibustion at Changqiang (GV 1) was applied. In the far-infrared therapy group, the infrared ray was radiated at Changqiang (GV 1). The treatment started in 10 min after dressing change in the two groups. Totally, 8 treatments were required. The time requirement being equal to or less than 2 score in the assessment face scale (AFS), the case number of pain relief in 10 min after treatment and the intention of the two therapies after everyday dressing change were observed in the patients of the two groups.
RESULTSIn the moxibustion group, the time of pain relief was shorter than that of the far-infrared therapy group [(11.5 +/- 3.9) min vs (17.8 +/- 3.8) min on the 1st day; (9.4 +/- 3.6) min vs (15.2 +/- 4.3) min on the 2nd day; (7.8 +/- 2.7) min vs (14.3 +/- 3.2) min on the 3rd day; (6.4 +/- 3.3) min vs (10.5 +/- 2.9) min on the 4th day; (5.9 +/- 2.9) min vs (11.2 +/- 1.9) min on the 5th day; (5.3 +/- 2.2) min vs (8.8 +/- 2.3) min on the 6th day; (5.4 +/- 1.8) min vs (9.2 +/- 2.1) min on the 7th day; (5.1 +/- 1.4) min vs (9.5 +/- 2.6) min on the 8th day, all P < 0.05]. The case numbers of pain relief in 10 min after treatment were 74 cases, 75 cases, 77 cases and 78 cases from the 1st to the 4th day separately in the moxibustion group, which were much more than 63 cases, 65 cases, 68 cases and 69 cases in the far-infrared therapy group (all P < 0.05). The treatment intention scores in the moxibustion group were better than those in the far-infrared therapy group (all P < 0.05).
CONCLUSIONThe warm suspending moxibustion at Changqiang (GV 1) relieves pain rapidly in the dressing change of much more patients after perianal abscess surgery in much shorter time as compared with the far-infrared therapy. Moreover, the patients have more expectation to be treated with moxibustion therapy.
