Objective To study the clinical application of endoscopic retrograde cholangiopancre-atography(ERCP)combined with biliary microlithiasis exploration in acute cholangitis.Methods The clinical data of consecutive 54 cases of acute cholangitis were analyzed.Before ERCP,all cases were examined by routine examinations,including abdominal uhrasonography,CT or magnetic resonance cholangiopancre atography(MRCP).The bile Was collected through ERCP or endoscopic mtsobiliary drainage(ENBD),then all the samples were choked by polarization microscope.Results Thirty-six cases(66.67%)out of 54 patients with common bile duct(CBD)stones or dilation of common bile duct were diagnosed by routine examination.ERCP Was performed in all patients,only 3 cases failed,and the rest were successful.Through ERCP,39 cases with CBD stones(76.47%),4 cases with CBD inflamnmtory smcmre were diagnosed,and 12 cases were normal.Among the 12 cases,9 cages were found with biliary microlithiasis by polarization microscope.The diagnostic effectiveness of ERCP combined with biliary microlithiasis exploration was highest(94.12%),and there Was significant difference between them(P＜0.05).Conclusions It may improve the diagnostic accuracy to combine ERCP with biliary microlithiasis exploration in CBD stones.Biliary microlithiasis may play an important role in the pathogenesis in unknown aetiology acute unexplained cholangitis.

Objective To investigate the psychological characteristics and personality of perinatal women, and to provide evidence for effective psychological intervention. Methods Five hundred and seventy pregnant women were randomly selected from the out-patient department from October, 2002 to March, 2003. Eysenck Personality Questionnaire(EPQ) , Self-rating Anxiety Scale(SAS) and Self-rating Depression Scale(SDS) were applied for their personality, psychological characteristics and the influencing factors. Psychological surveys were performed in 216 cases in labor, and 300 cases were followed up during 1-5 days and 42-60 days postpartum. Results During pregnant period, the incidence of anxiety and depression was 10. 5% and 10. 2%, respectively, while 4. 0% and 5. 3% during early stage of puerperium. The rate of depression was 40. 7% and 10. 0% during late stage of puerperium and after puerperium. Pregnant women with personality of stability were less likely to have psychological disorder. Conclusions The rate of psychological disorder varies in different per sonallity. Proper intervention among high risk pregnant women is important in perinatal psychological

Parkinson's disease (PD) is a complicated disease, commonly diagnosed among the elderly, which leads to degeneration of the central nervous system. It presently lacks an effective therapy for its complex pathogenesis. Adverse effects from Western drug-based medical intervention prevent long-term adherence to these therapies in many patients. Traditional Chinese medicine (TCM) has long been used to improve the treatment of PD by alleviating the toxic and adverse effects of Western drug-based intervention. Therefore, the aim of this study is to evaluate the efficacy and safety of Xifeng Dingchan Pill (XFDCP), a compound traditional Chinese herbal medicine, taken in conjunction with Western medicine in the treatment of PD patients at different stages in the progression of the disease.

Objective To explore the value of trypsinogen activation pepfide (TAP) levels in blood plasma and urine in the diagnosis of acute pancreafitis at early stage and severity predicting combined with the CT results. Method Sixty-five patients with acute pancreatitis who scanned with enhanced CT were di-vided into mild acute pancreatitis (MAP) group and severe acute pancreatitis (SAP) group according to the CT results, 29 patients with acute abdomen except for acute pancreatitis were as control group. TAP levels in blood plasma and urine were measured in all patients. Results At the time of 6, 12 and 24 h after admis-sion, the level of blood plasma TAP in SAP group ( > 9.0 nmol/L) was significantly higher than that in MAP group(< 3.5 nmol/L), there were significant differences between SAP group and MAP group or control group (P<0.05). And the median urinary TAP in SAP group (102.8, 78.2, 52.3 nmol/L)was significantly higher than those in MAP group (32.5, 28.7, 25.6 nmol/L)and control group(12.6, 12.2, 11.5 nmol/L), there were significant differences among three groups (P<0.05). At the time of 3, 5 d after admission, there was no significant difference in TAP levels in blood plasma and urine among three groups (P>0.05). Conclusions Early dynamic detection of TAP levels in blood plasma and urine is of higher diagnostic value and predictive value for acute pancreatitis, which is of benefit in the early diagnosis and treatment of acute pancreatitis.

BACKGROUND:Eucommia ulmoides gum has good thermoplastics, liquidity, bondability and antimicrobial properties. However, the application of Eucommia ulmoides gum as a root canal filing material is rarely reported. OBJECTIVE: To compare the different contents of gas phase nano-silica on mechanical performance of composite material taking the gutta-percha as the matrix, and observe the effect of the root canal filing. METHODS:Four kind of root canal filing materials were prepared through adding barium sulfate (20%), nano-hydroxyapatite (10%) and different contents of gutta-percha and gas phase nano-silica (40% and 15%, 45% and 20%, 50% and 25%, 55% and 30%). PureEucommia ulmoidesgum served as the blank control. The mechanical properties (hardness, tensile strength and rupture elongation rate) of those five materials were detected. Furthermore, four kinds of composite materials, pureEucommia ulmoidesgum and Gutta-Percha Pelets were filed into the fresh extracted premolar root canal by using Obtura II technology. The effect of root canal filing was observed under X-ray and scanning electron microscopy.RESULTS AND CONCLUSION: Along with the increase of the content of gas phase nano-silica, the hardness of Eucommia ulmoides gum composite material increased, tensile strength increased firstly and then decreased, and rupture elongation rate decreased. PureEucommia ulmoides gum was transmitted to the X-ray and no image of filing material was obtained. Four kinds of composite materials were resistant to X-ray, and images showed that al composite materials were equaly filed into the root canal, without cacuole, and were in contact with the root canal inner wal, showing good filing effect. Scanning electron microscopy showed that, fingerlike projections were the longest at the surface of pureEucommia ulmoides gum; as the content of gas phase nano-silica increased, fingerlike projection length reduced at the surface of composite materials.Eucommia ulmoides gum composite materials could be developed as a canal filing material under heat flow condition.

Objecltive To intensify the coordination and nursing in the operation room in order to prevent surgical site infection after gastrointestinal operation. Methods 337 medical history of patients received gastrointestinal operation and third rate healing from 1999 to 2006 were collected. A series of intensified measures were applied to surgical site infection from 2003 gradually, including invocation of new surgical handwashing method, modified skin disinfection manner, adoption of degreasing with ethanol first before disinfection with iodophor, placement of incision protector and clean bag for incision protection after entering abdomen, changing to use new gastrointestinal anastomofic thimerosal,standardization of operation order and clean manage-ment in operation room. The incidence rate of surgical site infection after gastrointestinal operation of patients from 1999 to 2002 and from 2003 to 2006 underwent χ2 test. Results The incidence rate of surgical site in-fection after gastrointestinal operation greatly decreased after adoption of intensified nursing intervention, Signifi-cant difference existed in rate of patients with third rate healing between the year 1999 to 2002 and 2003 to 2006. Conclusions Modified nursing intervention for surgical incision after gastrointestinal operation can de-crease incision infection rate evidently.

Objective To quantitatively investigate the expression levels of the cytosine deaminases,hA3B,hA3F and hA3G in peripheral blood mononuclear cell(PBMC)of human immunodeficiency virus(HIV)infected patients and to analyze the correlation between cytosine deaminases expression and CD4~+ T lymphocyte counts. Methods Peripheral blood samples were collected from 21 HIV-infected subjects who didn't take antiretroviral therapy(ART-),21 HIV-infected subjects receiving ART(ART+),and 10 HIV-uninfected subjects. PBMC were isolated by Ficoll density gradient centrifugation, followed by RNA extraction and cDNA synthesis.hA3B,hA3F and hA3G mRNA levels were determined by real-time fluorescent quantitative polymerase chain reaction(PCR).CD4~+ T lymphocyte counts were determined using flow cytometry. Data were analyzed by t test, t' test or Wilcoxon rank sum test. Results In HIV-infected subjects without or with ART,HIV-uninfected subjects, the levels of hA3B mRNA were 208.4,365.2 and 563.6,hA3F mRNA were 245.5,316.6 and 442.9,hA3G mRNA were 404.6,360.8 and 638.6,respectively.hA3G mRNA level in HIV-infected subjects was lower than that in HIV-uninfected controls(P=0.0131),but there was no statistical difference between ART+ and ART-groups(P=0.7342).There were no correlations between hA3B,hA3F and hA3G mRNA levels and CD4+ T lymphocyte counts in either ART-or ART+HIV-infected subjects(ART-:r=-0.0104,r=-0.0545,r=0.1623,all P＞0.05;ART+:r=0.3220,r=0.2193,r=0.1455,all P＞0.05).In addition,hA3B,hA3F and hA3G mRNA levels were positively correlated with one another in ART-HIV-infected subjects and HIV-uninfected controls(P＜0.05),but not in ART-HIV-infected subjects(P＞0.05).Conclusions hA3B,hA3F and hA3G expression levels do not directly correlate with CD4~+ T lymphocyte counts in HIV-1-infected patients,hA3B,hA3F and hA3G expression levels in PBMCs tend to he decreased after HIV-1 infection, and ART may increase hA3B and hA3F mRNA expression.
