Objective To evaluate the effect of electroacupuncture on postoperative cognitive func?tion in elderly patients undergoing carotid endarterectomy. Methods Fifty patients of both sexes, aged≥65 yr, of American Society of Anesthesiologists physical status Ⅱ orⅢ, with the educational level≥ the level of primary school, scheduled for elective unilateral carotid endarterectomy, were divided into 2 groups ( n=25 each) using a random number table: control group ( group C) and electroacupuncture group ( group EA). In group EA, electroacupuncture (frequency 2∕100 Hz, intensity 5-12 mA) of Baihui (GV20), Neiguan (PC6) and Zusanli (ST36) was performed throughout surgery starting from 30 min before opera?tion, and then general anesthesia was performed. General anesthesia was performed directly in group C. Before operation ( T0 ) , at the end of operation ( T1 ) and at 24 h after operation ( T2 ) , blood samples were collected from the internal jugular vein for determination of plasma S?100βprotein, tumor necrosis factor?αand brain?derived neurotrophic factor ( BDNF) concentrations by enzyme?linked immunosorbent assay. The cognitive function was assessed using Montreal Cognitive Assessment at T0,2 and at 3 and 7 days after opera?tion ( T3,4 ) . Results Compared with group C, the Montreal Cognitive Assessment scores were significantly increased at T2?4 , the plasma S?100β protein and tumor necrosis factor?α concentrations were significantly decreased at T1,2 , and the plasma BDNF concentrations were significantly increased at T2 in group EA ( P<0?05) . Conclusion Electroacupuncture can improve postoperative cognitive function in the elderly pa?tients undergoing carotid endarterectomy, which may be related to inhibition of inflammatory responses,
promotion of BDNF production and reduction of brain injury.

The chalcone synthase (CHS) superfamily of the type III polyketide synthases (PKSs) generates backbones of a variety of plant secondary metabolites. Benzalacetone synthase (BAS) catalyzes a condensation reaction of decarboxylation between the substrates of 4-coumaric coenzyme A and malonyl coenzyme A to generate benzylidene acetone, whose derivatives are series of compounds with various biological activities. A BAS gene Pcpks2 and a bifunctional CHS/BAS PcPKSI were isolated from medicinal plant P. cuspidatum. Crystallographic and structure-based mutagenesis studies indicate that the functional diversity of the CHS-superfamily enzymes is principally derived from small modifications of the active site architecture. In order to obtain an understanding of the biosynthesis of polyketides in P. cuspidatum, which has been poorly described, as well as of its activation mechanism, PcPKS2 was overexpressed in Escherichia coli as a C-terminally poly-His-tagged fusion protein, purified to homogeneity and crystallized, which is helpful for the clarification of the catalytic mechanism of the enzyme and lays the foundation for its genetic engineering manipulation.

Objective To analyze the imaging features of congenital spinal deformity (CSD) associated with split cord malformation (SCM) and other intraspinal abnormalities, and to investigate the relationship to neurological symptoms. Methods 105 cases CSD with SCM were retrospectively studied. Analysis the imaging features of SCM (including type of SCM, location of SCM, location and apical vertebrae, symmetry of divided cord) and other intraspinal abnormalities. To investigate the relationship of the factors and neurological symptoms using Chi?square test of one factor and multiple factors logistic regression analysis. Re?sults 28 cases (26.7%) were formation failure, 33 cases (31.4%) were segmentation failure, and 44 cases (41.9%) were combina?tion of 2 disorders. 41 cases had neurological symptoms, 64 cases were asymptomatic. The distribution of SCM combined with spi?nal deformities:thoracic (11 cases), thoracolumbar (18 cases) and lumbar (20 cases) in type I SCM, thoracic (31 cases), thoracolum?bar (20 cases) and lumbar (5 cases) in type II, none was in cervical. The location of SCM upper than apical vertebrae 29 cases, on apical vertebrae 25 cases, lower than apical vertebrae 51 cases. Spinal cord was splitted symmetric 27 cases and asymmetric 78 cases. 66 cases combined with other intraspinal abnormalities, lower conus 42 cases, syringomyelia 38 cases, meningocele 10 cas?es and sakrale zyste 5 cases. Associated with intraspinal abnormalities, the rate of neural symptoms was different. According to Chi?square test of one factor and multiple factors logistic regression analysis, lumbar SCM, spinal cord asymmetric and lower conus were related with neurological symptoms. Conclusion The predilection spinal deformity of type I is combination, type II SCM is segmentation failure. When SCM patients associated with other intraspinal abnormalities, the incidence of neurologic symptoms is increased. The lumbar SCM, hemicords asymmetry and lower lying conus have significant relationship with neurologic symptoms.

OBJECTIVETo explore the effects of moxibustion with seed-sized moxa cone at "Ganshu" (BL 18) on liver furiction and morphology in rat with precancerous lesion of hepatic cellular cancer MCC).

METHODSA total of 60 male Wistar rats were randomly divided into a normal group (10 rats), a model group (20 rats), a 20-day treatment group (15 rats) and a 40-day treatment group (15 rats). HCC model was established by intraperitoneal injection of diethylnitrosamine (DEN). Rats in the normal group received no treatment. Rats in the model group were treated with fixation. Rats in the 20-day treatment group and 40-day treatment group were treated by moxibustion with seed-sized moxa cone at "Ganshu" (BL 18), once every other day, for 20 days and 40 days, respectively. Blood sample in each group was collected 1 d before model establishment, 20 d, 40 d and 84 d after model establishment. Chemical method was applied to test the activity of ALT (alamine aminotransferase), AST (aspartate transaminase) and GGT (glutamyl transpeptidase); at the end of model establishment, all the rats were sacrificed to observe the liver morphology changes.

RESULTSAfter the first therapeutic course, the. content of ALT and AST in the 20-day treatment group was significantly lower than that in the model group (all P<0. 05); after the second therapeutic course, the content of ALT, AST and GGT in the 40-day treatment group was insignificantly lower than that in the model group (all P>0. 05). Under light microscope, the slice of liver tissue indicated that primary tumor was induced in the model group, and the tumor cells were stained and irregular; the cytoplasm in the 20-day treatment group was even, and the tumor cells were few with several nodules alone. In the 40-day treatment group the liver morphology was normal and the staining was even; the tumor cells were few without nodules or a few. Conclusion Moxibustion with seed-sized moxa cone at "Ganshu" (BL 18) could reduce the serum content of ALT, AST and GGT in rats with HCC, which could protect the liver and: delay the DEN-induced precancerous lesion on some levels.
