Treatment data of approximately 6000 patients before and after implementation were compared. Results The error rate was reduced from 17% to 09% after using the entire QA workflow management. Conclusions Entire QA workflow management effectively improves the accuracy and safety of radiotherapy.

The purpose of the present study was to explore whether substance P (SP) modulates the response mediated by GABAA receptors. Experiments were carried out on cultured hippocampal pyramidal neurons of rats. GABA-activated inward currents were recorded using the whole-cell-patch-clamp techique. The majority of the neurons examined (66/92, 72%) were sensitive to both GABA and SP. When the neurons were treated with SP prior to application of GABA, the GABA-activated current (IGABA) was inhibited markedly, which was concentration-dependent and could be blocked by spantide, an NK1 receptor antagonist. With 10－8, 10－7, 10－6 and 10－5 mol/L SP, IGABA was inhibited by 18%, 24.8%, 25.9% and 28% respectively. Intracellular application of H7, a potent inhibitor of PKC, abolished inhibition of IGABA by SP, suggesting that the inhibition of IGABA by SP may be a result of intracellular phosphorylation of the GABAA receptor.

OBJECTIVETo explore clinical effect of manipulative reduction and percutaneous K-wires fixation in treating supracondylar fractures of the humerus in children.

METHODSFrom July 2010 to December 2012, clinical data of 52 children with supracondylar fractures of the humerus, which treated with manipulative reduction and percutaneous K-wires fixation, were retrospectively analyzed. Among them, there were 35 males and 17 females with an average age of 6.7 (ranged from 2.5 to 12) years old. All fractures were type Garland II - III fractures, and 51 cases were extension type and 1 case were flexion type. Flynn evaluation standard of elbow performance score were applied to evaluate clinical effects.

RESULTSAll patients were followed up from 12 to 18 months with average of 16 months. According to Flynn evaluation standard of elbow performance score, 41 cases obtained excellent result, 8 good and 3 moderate.

CONCLUSIONManipulative reduction and percutaneous K-wires fixation for the treatment of supracondylar fractures of the humerus in children has many advantages, such as minimally invasive, rapid recovery, stable fixation. It could prevent osteofascial compartment syndrome, Volkmann Contracture and cubitus varus.

Objective To investigate the relationship between the characteristics of psychological defense style and clinical symptoms of eating attitude in patients with anorexia nervosa patients. Methods Totally 92 ca?ses ( 46 cases of restricting type,46 cases of binge?eating/purging type,48 cases of early onset before 16 years old, 44 cases of late onset after 16 years old) meeting the Diagnostic and Statistical Manual of Mental Disorders,Forth Edition ( DSM?4) for anorexia nervosa (AN) were collected.92 gender?marriage?and education?matched normal cases in a psychiatric hospital were selected as the healthy control group(HC) .All were assessed with defensive style questionnaire(DSQ) and eating attitude test?26(EAT?26).DSQ and EAT?26 were compared between AN and HC,between early onset of AN( before 16 old years) and late onset of AN( after 16 old years) ,and between AN?R and AN?P.Then correlation study was done for the AN. Results Compared with HC,AN showed higher scores in the immature defense,neurotic defense ((4.49±1.13)vs (3.55±0.93),(4.33±0.76)vs (3.88±0.69), P<0.001), and higher EAT?26 median total and factor scores of dieting scale items,bulimia&food preoccupation scale items, oral control subscale items (P<0.01).Compared with AN?R,AN?P showed higher scores in the immature defense ((4.49±1.03)vs (4.79±1.13), P=0.01),and higher EAT?26 median total and factor score of bulimia&food pre?occupation scale items (P<0.05, P<0.01).The correlations between immature defense and EAT?26 total score,be?tween neurotic defense and EAT?26 total score were significant( r=0.472, P<0.001;r=0.315, P=0.002). The correlations between immature defense and EAT?26 dieting score, between neurotic defense and EAT?26 dieting score were significant( r=0.343, P<0.001, r=0.257, P=0.014).The correlations between immature defense and EAT?26 bulimia & food preoccupation score,between neurotic defense and EAT?26 bulimia & food preoccupation score were significant( r=0.523, P<0.001, r=0.267, P=0.010).The correlations between immature defense and duration were significant( r=0.375, P<0.001).The correlations between all defense factors and BMI were not sig?nificant( r=-0.15?0.25, P>0.05) . Conclusion AN patients tend to use more immature defense and neurotic de?fense compared with HC,and AN?P patients use more immature defense compared with AN?R. Immature defense and neurotic defense are related to the eating attitude,and the immature defense is related the duration.

Danshen,an efficacious agent for cardiovascular diseases,has been found to play an essential role in kidney injury.In the present study,the effect of Danshen on cisplatin-induced renal dysfunction was investigated in a mouse model.Danshen was administered to mice at a dose of 3 g/kg 4 days before and 3 days after cisplatin treatment.A single intraperitoneal injection of 20 mg/kg cisplatin was used to induce nephrotoxicity.The mice were sacrificed 72 h after cisplatin intoxication.Biochemical parameters including serum creatinine and blood urea nitrogen were analyzed.Histopathological changes of kidney tissues were detected using HE staining.Antioxidant enzymes (GSH-Px and SOD) and peroxidative product (MDA) were detected.Protein expressions of Nrf2 and its target genes including HO-1 and NQO1 were measured by Western blotting.The results showed that pretreatment with Danshen significantly reduced serum creatinine and blood urea nitrogen in the cisplatin-treated mice.Histopathological examination showed that Danshen mitigated the renal damage induced by cisplatin.Moreover,Danshen restored the activities of antioxidant enzymes (GSH-Px and SOD) and normalized the MDA contents in renal tissues.Western blotting revealed that Danshen enhanced the expressions of Nrf2 and its target genes in cisplatin-exposed mice.It was suggested that Danshen protects against the cisplatin-induced renal impairment in the mice,which is potentially associated with the upregulation of Nrf2-mediated signaling pathway.

OBJECTIVETo analyze the polymorphism of natural killer cell immunoglobulin-like receptor (KIR)gene and the characteristics of its genotypes and haplotypes in Korean ethnic group of Jilin area, and to compare with that of Han nationality.

METHODSDNA samples randomly collected from 214 Han and 160 Korean populations were genotyped with PCR-SSP method, and KIR genotypes and haplotypes were assigned according to the standard model by Hsu et al.

RESULTSAll individuals contain KIR 3DL3, KIR 2DL4, KIR 3DL2 with the genotype frequency of 100%; the most common genotypes were 2DL1, 2DL3, 3DL1, 3DP1(*)003 and 2DP1; the genotypes with low frequency were 2DL2, 2DS2, 2DS3, 3DP1(*)001/002/004. Thirty-nine different KIR genotype and 16 haplotypes had been found in Korean and Han individuals. The most common KIR genotypes were AJ and AF with frequency of 18.1%, 19.4% and 31.8%, 19.6%, respectively. The most common KIR haplotype was haplotype 2 with frequency of 41.8% (n = 127) and 51.2% (n = 216) (P < 0.05), respectively.

CONCLUSIONKIR gene distribution in Jilin Korean ethnic group showed some common features of KIR gene polymorphisms in Chinese Han population, but also showed this nation's unique characteristics of KIR gene polymorphism.
