Objective To explore the effect of Curcumae on acute hepatic injuried mice.Methods The model mice of acute hepatic injury were established with intraperitoneal injecting 0.2% carbon tetrachloride (CCl4) 0.2 ml/10mg. 48 mice were randomized into 6 groups: model group, control group, Ganlixin group (25 mg/kg) and three treating groups of Curcumae which were administrated by gavage at the doses of 2.5 g/kg, 5 g/kg, 10 g/kg once everyday.7 d later, all mice were put to death. The liver index, the activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST) in serum, the activities of superoxide dismutase (SOD) and the content of malondialdehyde (MDA) in hepatic tissue were observed. Pathological change was observed under HE staining. Results Compared with the model group, Curcumae could decrease the liver index and the activities of ALT and AST in serum, MDA in hepatic tissue significantly (P<0.05), and increase the activities of SOD (P<0.05). The pathological changes were less in three treating groups than that of the models. Conclusion Curcumae can protect the liver from acute hepatic injuried induced with CCl4 in mice.

Objective To investigate the spherical diopter and astigmatism change of humans at sitting and supine position.De- sign Prospective case series.Participants 96 eyes of 52 patients (spherical diopter from-2.50 D to-10.00 D,astigmatism diopter from -0.75 D to-4.50 D) were selected.Methods The subjects were examined with NIKON portable retinomax at sitting and supine posi- tion,respectively.Main Outcome Measures The spherical diopter,cylinder diopter and axis change were analyzed statistically.Re- sults Spherical diopter at supine position (-5.31?3.43 D) was a little higher than that at sitting position (-5.27?3.24 D) statistically(P= 0.25),and cylinder diopter at sitting position (-2.27?1.24 D) and at supine position (-2.35?1.19 D) was no statistically difference (P= 0.20).The axis of astigmatism changed from-16?to +18?.Axis change was within 2?in 52.1% eyes,6?-10?in 5.2%,over 10?in 3.1%. The change of axis rotation tended to counter-clockwise in the right eye and clockwise in the left eye.Conclusions Eye rotation at sit- ting and supine position may cause the astigmatism axis change.It may be one of the main factors affecting the results of LASIK.

Objective To study the distribution of variable number tande repeat(VNTR) polymorphisms of the platelet membrane glycoprotein Ⅰ b? in Han nationality at Harbin and the relationship between these polymorpbisms and cerebral infarction(CI).Methods The identification of alleles and genotypes of VNTR polymorphism of the glycoprotein Ⅰ b? gene was performed by polymerase chain reaction (PCR)in 200 healthy individuls and 200 CI patients(77 lacunar infarction patients and 123 atherosclerotic thrombotic infarction patients),to analyze The relationship between gene polymorphisms and cerebral infarction.Results(1)There were three types of alleles:B、C、D,and five types genotypes:BC,BD,CC, CD,DD in Harbin Han nationality.No person with A allele and BB genotype was found.(2)No statistically significant differences of GP Ⅰ b? gene VNTR polymorphism was found between CI patients or subtype CI patients and controls(P=0.412 and 0.572,respectively).Conclusions(1)This study indicates that the C and D alleles of VNTR polymorphisms of GP Ⅰ b? are the main alleles while the CC and CD genotypes are the main genotypes in Harbin Han people.(2)Our findings indicate that no association exists between the VNTR polymorphism of platelet GP Ⅰ b? gene and CI.

Objective To compare the efficacy and efficiency of simulation-based training of flexible fibreoptic intubation in novices with virtual reality simulator.Methods A total of 46 anaesthesia residents in their first stage of training in anaesthesiology with no experience in flexible fibreoptic intubation at Peking University People's Hospital were enrolled in the study,and were divided into 2 groups randomly,which were virtual reality simulator group (group S,n=23) and manikin group (group M,n=23).The group S was then trained for 25 times on simulator,while the group M did the same processes on manikin.After training,participants in both groups had their performance assessed with the fibrescope evaluated through the oral route using a simulation manikin,who were instructed to attempt to advance the fibrescope 5 consecutive times to view the carina in the shortest amount of time.The time required to view the carina of each practice during training in both groups were recorded as pooled data to construct group learning curves with the application of SPSS 20.0.By using repeated measures analysis of variance and Ttest,the procedure time and global rating scale (GRS) of fibreoptic bronchoscope manipulation ability were compared between groups,so did the participant's confidence between before and after the training both within-subjects and between-subjects.Results The plateaus in the learning curves were achieved after 19 (15,26) practice sessions in group S and 24 (19,31) in group M,respectively.There was no significant difference in the procedure time [(13.7 ± 6.6) s and (11.9 ±4.1) s] and GRS [(3.9 ±0.4) vs.(3.7 ±0.3)]between groups.There were significant increases in participant's confidences in both groups after training [group S:(1.8 ± 0.5) vs.(3.9 ± 0.6),t=10.928,P=0.000;group M:(2.0 ± 0.7) vs.(3.9 ± 0.5),t=15.306,P=0.000],but there was no significant difference between groups.Conclusion The simulation-based training of flexible fibreoptic intubation in novices with virtual reality simulator is more efficient than the one with manikin,but the similar effects can be achieved in both modalities,after adequate trainings.In the related training a balance between time cost and economic cost should be considered and the appropriate teaching methods and forms should be taken.

Objective To explore the association of Gly71Arg mutation in gene of bilirubin uridine 5'-diphosphate-glucuronosyltransferase(UGT1A1)and neonatal jaundice in Beijing city Han population.Methods The genotypes and alleles of the Gly71 Arg polymorphism for UGT1A1 gene were identified by polymerase chain reaction-restricted fragment length polymorphism assay in infants of Beijing city Han population of China,including 96 infants with neonatal jaundice[serum bilirubin(307.06?38.5)?mol/L,indirect bilirubin(292.9?35.9)?mol/L] and 101 healthy control infants [serum bilirubin(131.2?42.1)?mol/L,indirect bilirubin(126.3?39.7)?mol/L].The genotypes and allele frequencies of the polymorphism were compared between infants with neonatal jaundice group and healthy infant group(control group).The effect of polymorphism in infants with neonatal jaundice group on serum bilirubin level were analyzed.Results There were significant differences in genotypes distribution in Gly71Arg polymorphism for UGT1A1 gene between the 2 groups(?2=9.47 P=0.002).Compared with control group,neonatal jaundice group had significantly higher Arg allele frequency in the polymorphism for UGT1A1 gene(?2=10.34 P=0.001).There were independent effects of Gly71Arg mutation in the gene on serum bilirubin level in neonatal jaundice group,at the carriers of homozygote of the Arg allele of Gly71Arg polymorphism had higher serum bilirubin levels compared to carriers of heterozygote of the Arg allele of the polymorphism and non-carriers of the Arg allele of the polymorphism(Pa

OBJECTIVETo explore the effect of Bushen Tiaojing Recipe (BTR) on the quality of oocytes, reproductive hormones, and the expression of bone morphogenetic protein-15 (BMP15) of in vitro fertilization-embryo transfer (IVF-ET) patients.

METHODSSixty infertility patients who prepared for IVF-ET were assigned to two groups according to the treatment order, the treatment group [20 cases, treated with BTR + controlled ovarian hyperstimulation (COH)] and the control group (treated with COH alone, 40 cases). Age, the time limit for infertility, basal follicle-stimulating hormone (bFSH) concentration, usage days and the dosage of gonadotropins (Gn), serum levels of estradiol (E2), luteotropic hormone (LH), and progesterone (P) on the HCG injection day, the number of retrieved occytes, the fertilization rate, the number of embryos, the high quality embryo rate, and the clinical pregnancy rate were compared. Concentrations of follicle-stimulating hormone (FSH), LH, E2, testosterone (T), and P in the follicular fluid were detected via chemiluminescence microparticle immunoassay. The mRNA and protein expression of BMP-15 in mature granulosa cells was detected by real-time fluorescent PCR and Western blot.

RESULTSThirty-two patients were pregnant and the total pregnancy rate was 53.3%. Of them, 19 were pregnant and the total pregnancy rate was 47.5% in the control group, while 20 were pregnant and the total pregnancy rate was 65.0% in the treatment group. But there was no statistical difference between the two groups (P > 0.05). Compared with the control group, the Gn dosage was lower and the high quality embryo rate was higher in the treatment group, showing statistical difference (P < 0.05). There was no statistical difference in serum concentrations of E2, LH, or P on the HCG injection day, the number of retrieved oocytes, or the fertilization rate (P > 0.05). Compared with the control group, FSH concentrations in the follicular fluid were significantly lower and LH concentrations were significantly higher in the treatment group (P < 0.05). The LH concentrations in the follicular fluid were significantly higher in pregnant patients than non-pregnant patients, showing statistical difference (P < 0.05).There was no statistical difference in E2, T, or P concentrations (P > 0.05). The mRNA and protein expression of BMP-15 in granulosa cells was higher in the treatment group than in the control group (P < 0.05). It was also higher in pregnant patients than non-pregnant patients, showing statistical difference (P < 0.05).

CONCLUSIONDuring the IVF-ET process, BTR could elevate the quality of oocytes, and increase the sensitivity of ovarian follicles to exogenous Gn, which was correlated with the mRNA and protein expression of BMP-15 in granulosa cells, and changing concentrations of FSH and LH.

Literature about functional dyspepsia treated with acupuncture in recent 5 years is retrieved in China National Knowledge Infrastructure (CNKI), Wanfang database and PubMed. The research achievements are arranged and summed up to explore the mechanism of acupuncture for functional dyspepsia. It is found that acupuncture can regulate the secretion of braingut petide, and cause the coordination response of limbic system-brain. Also, it adjusts serum molecule metabolin and the gene expression of the transduction pathway of adjustment signal for rats. It is believed that functional dyspepsia treated with acupuncture is through multiple ways, and adjusting the function of braingut axis is one of the important mechanisms.

ObjectiveTo assess the relationship of filaggrin expression with atopic diathesis and disease severity in patients with alopecia areata (AA).MethodsThirty-seven patients with AA aged (26.3 ± 10.6) years were enrolled in this study.Atopic diseases were noted in 8 of these patients.Clinical data and laboratory test resuhs were reviewed.Immunohistochemical staining was performed to quantify the expression of filaggrin protein in scalp biopsy specimens from all of the 37 patients with AA and from 10 human controls,and fluorescence-based semiquantitative reverse transcription-PCR to detect the expression of filaggrin mRNA in scalp biopsy specimens from 22 patients with AA and 13 healthy controls.Data were statistically analyzed by Mann Whitney U test,chi-square test,and Spearman's rank correlation test.ResultsThe expressions of filaggrin protein and mRNA were significantly lower in patients with AA than in the controls(P ＜ 0.05 or 0.01 ),and the decrease seemed more obvious in patients with large areas of lesions,long duration of disease,and nail abnormalities,but the degree of decrease was unrelated to the complication with atopic diseases.No significant differences were observed in sex ratio,age at onset,disease duration,area of hair loss,the prevalence of family history or incidence of nail abnormalities and increase in serum IgE and eosinophils,between patients with atopic diseases and those without.ConclusionsThe expressions of filaggrin protein and mRNA are decreased in patients with AA,suggesting that filaggrin may participate in the development of AA and is correlated with the severity of AA.

Objective To observe the microstructural changes in lesions of alopecia areata (AA) with dermoscopy and to evaluate their correlation with clinicopathological manifestations. Methods The area of alopecia of 62 patients with AA and 44 patients with other types of hair loss were observed by using a noncontact polarized dermoscope (Dermlite, USA). Clinical data on and laboratory findings from these patients were collected. Pathological examination was carried out with scalp biopsy specimens from the alopecia area of 15 AA patients. Results Characteristic dermoscopic signs of AA included yellow dots, black dots, broken hairs, exclamation mark hairs, short vellus hair and newly-grown short hairs. Among these signs, yellow dots showed the highest prevalence (83.9%). Exclamation mark hairs, black dots and broken hairs were rather specific signs for AA, and the prevalence of the three signs was positively correlated with disease activity and positivity rate of hair-pull test. A positive correlation was also noted between the prevalence of elevated thyroid peroxidase antibody levels and positivity rate of hair-pull test (r = 0.269, P ＜ 0.05 ) as well as prevalence of broken hairs (r = 0.445, P ＜ 0.05), and between the prevalence of yellow dots and that of keratinous plug in follicular orifice. There was a negative correlation between the prevalence of newly-grown short hairs and perifollicular mast cell infiltration and between the prevalence of black dots and the anagen/catagen ratio. Conclusions Yellow dots can serve as a preliminary screening marker for AA. Exclamation mark hairs, black dots and broken hairs are highly sensitive for the confirmation of diagnosis of AA, and often predict progressive AA.Dermoscopic signs are well correlated to the histopathology features of AA, and may be useful for the evaluation of disease severity and guidance on the treatment of AA.
