Professor LIU Qingguo's academic thoughts and clinical experience in treating pediatric tic disorders with scalp fire needling is introduced. Professor LIU believes that the core pathogenesis of this disease lies in "wind stirring and qi disorder, leading to the spirit failing to govern the body". Therefore, treatment should focus on "regulating the spirit to stabilize the form and extinguishing wind to stop movement". Clinically, the main acupoints include Shenting (GV24), Benshen (GB13), Xinhui (GV22), Baihui (GV20), Sishencong (EX-HN1), Fengchi (GB20), and Fengfu (GV16), which are rapidly punctured with fine fire needles, leading to significant therapeutic efficacy.

Objective To investigate the clinical characteristics and its prognostic factors for hilar cholangiocarcinoma with exairesis .Methods The clinical data of 58 cases of hilar cholangiocarcinoma were ret-rospectively analyzed .The Kaplan-Meier method was used to estimate the overall survival and disease specific survival rates for these patients .And the factors that may influence the prognosis and survival of patients were an -alyzed using univariate(log-rank test)and multivariate Cox proportional hazard models .Results The median survival time was 22 months for all patients .The 1-,3-and 5-year survival rates were 76%,40%and 21%, respectively.Univariate analysis showed that preoperative albumin (P=0.002),intraoperative blood loss (P=0.039),surgical method(P =0.006),histologic differentiation(P =0.001),portal vein encroached(P =0.014),surgical margin(P=0.020)were correlated factors for postoperative survival duration .Multivariate analy-sis by Cox Proportional Hazard Model showed that surgical method (P=0.022),histologic differentiation(P=0.020)were independent prognostic factors for patients with Hilar cholangiocarcinoma excised .Conclusion Low albumin leve,intraoperative blood loss more than 500 mL,low degree of tumor differentiation,portal vein en-croached ,radical surgery ,positive surgical margin are risk factors for total survival of Hilar cholangiocarcinoma .

Objective To investigate high risk human papillomavirus(HR-HPV)prevalence among married women in Beijing and to study the high risk flactors.nethods During March 2007 to September 2008.a total of 6185 married women sampled from 137 communities in 12 districts were screened bv HR-HPV DNA test and cytogical test.The interview was carried out with unified questionnaires.The databage was set up and twice entered in EpiDam 3.0.After checked up,the data were analyzed in SPSS 15.0.Results (1) The HR-HPV infection rate was 9.89%.The HR-HPV infection rate of the city zone,the suburb and the exurb were 9.34%,10.51% and 9.51% (P>0.05).The HR-HPV infection rate of the native and the oudander were 9.53%,11.30% (P<0.05).(2) The age distribution of HR-HPV infection was that the rate was around 10% among 25 to 44 age groups,which was the highest(11.21%) in 30 to 34 age group;then the rate was descended as the age raising,the rate of 50 to 54 age group was the lowest(7.78%).(3) Multiple logistic regression showed that the related risk factors of HR-HPV infection mainly included 1000 RMB and above of family income per person per month.possessing more than 1 sexual partner of her husband,outlander and hish levels of education.(4) The prevalence of cervical intraepithelial neoplasia(CIN)in HR-HPV positive group wag significantly higher than that in HR-HPV negative group(29.76% vs 3.32%,P<0.01).Conclusions(1)The HR-HPV infection rate among aged 25 to 54 years was 9.9% and there was no significant difference in area distribution.(2)The hish risk population which should strengthen screening was the married bearing-age women with high level of family income,outlander,high levels of education and her husband possessing more than 1 sexual partner.(3)HR-HPV infection is the main risk factor for CIN and cervical cancer.while does not provide a causal relationship with them.The high risk population should be checked regularly to understand the development of HR-HPV infection and CIN incidence.

The enantiomeric resolution of lactic acid was studied by reversed high performance liquid chromatography. β-cyclodextrin (β-CD), dimethyl (DM) and TM-β-CD were used as chiral mobile phase additives. The effects of different mobile phase, pH and concentration of chiral mobile phase additives on resolution of D,L-lactic acid were investigated. The results showed: the enantioselectivity of TM-β-CD was better than those of β-CD and DM-β-CD. D,L-lactic acid could be partly separated by DM-β-CD 　and could not be separated by β-CD, while it could be fully separated by TM-β-CD. As the concentration of TM-β-CD changed from 0.20　mmol/L to 1.00　mmol/L, The resolution varied slightly. The experiment of the effect of pH of mobile phase on Rs showed: as pH changed from 2.4 to 3.0, the Rs remain stable, and when pH＞3.1, the Rs decreased with the increase of pH. The RSD of retention time of L-lactic acid and D-lactic acid were 0.2% and 0.2%, respectively. The chromatographic systems with a dynamically-generated stationary phase with 2,3,6-tri-O-methyl-β-cyclodextrin proved to be an effective method for lactic acid enantiomer separation
