Objective: To investigate the status and influencing factors of substance-induced psychotic disorders in residents over 18 years old in Hebei Province, and to provide evidence for the prevention and control of substance-induced psychotic disorders. Methods: Using multi-stage stratified random sampling method, the permanent residents aged 18 years and over were selected from urban and rural areas in Hebei Province. The demographic data was collected, the 12-Item General Health Questionnaire ( GHQ-12 ) and eight risk factors about mental disorder questionnaire were used to find out mental disorders. The multivariate logistic regression model was conducted to analyze the influencing factor for substance-induced psychotic disorders. Results: A total of 23 675 questionnaires were sent out, 20 884 were valid ( 88.20% ).The weighted lifetime prevalence rates of substance-induced psychotic disorders, alcohol-related disorders, sedatives/hypnotics/anti-anxiety disorders and other substance-induced psychotic disorders were 6.20%, 5.93%, 0.24% and 0.04%, respectively. Multivariate logistic regression analysis showed that age ( 35-<45, OR=1.582, 95%CI: 1.091-2.292; 45-<60, OR=2.185, 95%CI: 1.524-3.132; ≥60, OR=2.061, 95%CI: 1.422-2.986 ), males ( OR=10.832, 95%CI: 8.265-14.196 ), urban area (OR=1.431, 95%CI: 1.202-1.703 ), non-poor family ( OR=2.291, 95%CI: 1.652-3.177 ), physical diseases ( OR=2.028, 95%CI: 1.678-2.452 ) and genetic history ( OR=1.574, 95%CI:1.181-2.098 ) were the influencing factors for substance-induced psychotic disorders. Conclusion The lifetime prevalence of substance-induced psychotic disorders among residents aged 18 years and over in Hebei Province is 6.20%, which is mainly related to age, gender, region, family economic situation, physical disease history and genetic history.

Objective To analyze MRI findings and its clinical significance in complications of polyamide hydrogel injection for augmentation mammoplasty. Methods The complication findings of MR imaging in 20 cases with polyamide hydrogel injection for augmentation mammoplasty were retrospectively reviewed and analyzed. Results In 20 patients, 26 breasts suffered from complications, including infection (n=5) with pieces of long T_1and long T_2 signals, aseptic inflammation (n=2) with pieces of slight long T_1and moderate T_2 signals, hard nodule (n=10) with long T_1 and long T_2 signals, and rupture (n=5) with pieces and nodes of long T_1 and long T_2 signals on MR images. Conclusion MRI has the great diagnostic value in the detection of complications after polyamide hydrogel injection for augmentation mammoplasty, and it should be taken as the first diagnostic choice.

Objective To observe anomalous genotypes of 4 multi-copy RM Y-STRs in Han population in Hubei province. Methods 252 unrelated male samples were ampliifed using reported and newly designed primers, then detected and analyzed by AB 3130 genetic analyzer. Results A total of 25 anomalous multi-band patterns were observed in 20 samples corresponding to an incident rate of 7.94%. 5 anomalous genotypes were observed in DYF387S1 locus, 15 in DYF399S1, 1 in DYF403S1 and 4 in DYF404S1. Four samples showed extra alleles in more than one locus. Conclusion Anomalous genotype has high incident rates in RM Y-STR markers and requires extensive attention in forensic practice.

Background and Purpose:Pancreatic cancer is malignant tumor of the digestive tract with poor prognosis and is not sensitive to conventional chemotherapy.This study investigates the safety and feasibility of regional arterial ligation followed by intra-arterial perfusion chemotherapy in 14 pigs divided into groups A,B and C.Methods:14 pigs were divided into 3 groups.Group A(n=5) underwent gastroduodenal artery ligation and catheterization through the right gastroepiploic artery.Group B(n=5) underwent splenic artery ligation and catheterization.Group C(n=4) underwent left periotic vein puncture.5-FU(20mg/kg) was perfused into these catheters in 60 min.Blood samples and pancreatic tissue were obtained for the purposes of the determination of drug concentration and pathological diagnosis.Results:At 80 min and 100 min the drug concentration in portal vein of group A and group B were higher than those of group C(P

Objective To investigate the diagnositic value of uhrasonography in fetuses with persistent right umbilical vein.Methods Three cases of persistent right umbilical vein diagnosed in our hospital were analyzed,including the sonographic findings and clinical outcome.Results In all cases the fetal gallbladder was located between the intraabdominal umbilical vein and the stomach,the umbilical vein was connected to the right portal vein,and the portal vein curved toward the stomach.Other intracranial malformations were detected in one case,and the baby died after birth.No addional malformations were found in the other two babies,and both of them were healthy at the age of 6 months.Conclusions Persistent right umbilical vein has typical prenatal sonographic appearances.The neonatal prognosis is favorable when other anomalies are ruled out.It's clinically important for early diagnosis and genetics consultation.

Objective To compare the differences of prescription pattern, adverse events, economic burden and drug-use adherence between preferred mood stabilizers and preferred antipsychotics in patients with bipolar disorder. Methods We investigated 240 cases of patients with bipolar disorder from 39 mental health institutions in 11 cities in Hebei province. The self-made questionnaire was used to investigate the demographic information, disease characteris-tics, prescription pattern and medical expense. The clinical global impression scale-severity of illness (CGI-SI) was used to assess the disease severity. The treatment emergent symptom scale (TESS) was used to assess the adverse drug reac-tions. The medication adherence rating scale (MARS) was used to assess drug therapy compliance in patients. Results One hundred fifty-two patients (63.3%) used antipsychotics as the first choice (antipsychotics group), 88 patients (36.7%) used mood stabilizers as the first choice (mood stabilizers group). The number of patients in-patient (90.1%vs. 76.1%), patients with psychotic symptom (27.0%vs. 11.4%), incidences of adverse events (46.1%vs. 31.8%), drug daily cost (me-dians 12.00 yuan vs. 8.37 yuan) and drug total cost (medians 344.61 yuan vs. 144.64 yuan) were larger in antipsychotics group than in mood stabilizers group (P<0.05). There was no significant difference between two groups in pattern of pre-scription, severity of adverse events and total scores of MARS (P>0.05). Conclusion The bipolar disorder patients more frequently use antipsychotics as the first choice in Hebei province. The use of antipsychotics does not alter the combina-tion medication pattern. In addition, antipsychotics cause a higher incidence of adverse events and heavier economic bur-den compared with mood stabilizers, suggesting that mood stabilizers should be the first choice to bipolar disorder.

OBJECTIVE:To provide reference for rational use of antipsychotic drugs in schizophrenia patients. METHODS:The general information and antipsychotic treatment information,which were extracted from the database of prior drug investigation in Mental Health Center of Hebei Province in 2002,2006 and investigation data in 2012 of 5014 schizophrenia patients,were ana-lyzed. RESULTS:Over time,the frequency of the first generation antipsychotic drugs decreased(P<0.05),while that of the sec-ond generation antipsychotic drugs increased (P<0.01). The frequency of long-acting antipsychotic drugs were generally low among outpatients and inpatients in 2002,2006,2012,with statistical significance(P<0.01). There were no significant difference in the proportion of outpatients receiving antipsychotic drugs combination treatment and monotherapy (P>0.05). Over time,the proportion of inpatients receiving monotherapy decreased,while that of inpatients receiving combination treatment increased (χ2=18.682,P<0.01). CONCLUSIONS:The second generation antipsychotic drugs have gradually replaced the first generation antipsy-chotic drugs,and have became the leading drugs in the treatment of schizophrenia in Hebei province. The proportion of inpatients receiving combination treatment has increased,which is different from the domestic and foreign prevention and treatment guide-lines.

Objective To develop a RP-HPLC method for the determination of Brucine and Strychnine in Semen Strychni and its extractive of total alkaloids. Methods A chromatographic column of Licrospher C18 (4.6 mm×250 mm, 5 μm) was used with the mobile phase of acetonitrile∶0.01 mol/L sodium heptane sulfonate and 0.02 mol/L potassium dihydrogen phosphate mixed with equal amount (adjusted pH to 2.8 with 10% phosphonic acid)=27∶73, detection wavelength at 260 nm, column temperature of 30 ℃ and flow rate of 1 mL/min. Results The calibration curves of Brucine and Strychnine were both in good linearity in the ranges of 0.1-1.0 μg and 0.12-1.2 μg (r=1.000) respectively. The average recovery rates of Brucine and Strychnine were 99.88% (RSD=1.06%) and 100.06% (RSD=0.78%) respectively. Conclusion The method is realiable and accurate, which can be applied to determination of Brucine and Strychnine in Semen Strychi and its extractive.

Objective To evaluate the ultrasonic characteristics of nasal bone absence at 16-34 weeks of pregnancy referring to fetal chromosomal anomalies. Methods The ultrasonic findings of the 20 fetuses with nasal bone absence at second or third trimester in Peking Union Medical College Hospital were reviewed referring to chromosomal karyotyping and labor induction or birth outcomes. Results The ultrasound features of the 20 fetuses including:(1) There were 17 fetuses showed bilateral nasal bones absence. The sonographic features were absence of hyper echo of nasal bone underneath the skin on either sagittal or transverse section. There were 5 fetuses showed multiple abnormalities:Four fetuses showed cardiac abnormalities (three showed atrioventricular septal defect, one showed ventricular septal defect, one showed ventricular septal defect with abnormal great vessels). One fetus showed duodenal obstruction′double bulbs′. The other minor abnormalities including short femur and humerus, increasing echogenetic bowels, aberrant right subclavian artery, mild unilateral ventriculomegaly, mild renal pelvic ectasia, outreached tongue, abnormal gestures of hands. (2) There were 3 fetuses showed unilateral nasal bone absence. The sonographic features were absence of hyper echo of either nasal bone on transverse section but with hyper echo on sagittal section. Two fetuses showed cardiac abnormalities (one fetus showed atrioventricular septal defect, one showed ventricular septal defect). The other minor abnormalities including short femur and humerus, hyper echogenetic bowels, increasing thickness of nuchal translucency or nuchal fold. Twelve fetuses were induced labor but only one had biopsy showed accordant result with ultrasound. (3) Karyotyping results:there were 9 of trisomy 21, 1 of 4p-and 7 of normal karyotype fetuses showed bilateral nasal bone absence. There were 2 of trisomy 21 and 1 of normal karyotype fetuses showed unilateral nasal bone absence. (4) Birth outcomes and follow-up:twelve fetuses induced labor but only one fetus had biopsy. Eight fetuses were born until term and 5 fetuses showed normal in follow-up. The results of twelve fetuses showed concordant with ultrasonic ifndings. Conclusions Characteristics of the nasal bone absence are absence of bilateral or unilateral nasal bones. If we ifnd nasal bone absence in prenatally ultrasound screening, the karyotyping should be recommended in order to detect chromosomal abnormalities especially trisomy 21.

Objective The aim of the study was to determine the placenta volume (PV) at 11-13+6 weeks of gestation by three-dimensional ultrasound (3DUS) in combination with birth weight, placenta weight, placenta volume at birth and maternal age, body mass index (BMI) additionally. Methods From June 2011 to July 2012, placental volumes were prospectively measured by VOCAL (Virtual Organ Computer-aided Analysis) method in 129 normal pregnancies of Peking Union Medical College Hospital at 11-13+6 weeks of Gestation, multiples of the median was calculated (MOM) after logarithmic10 transformation referring to different crown-rump length (CRL) groups. The normal pregnancies were selected without any combinations or fetal abnormalities, then recorded the birth weights, placenta diameters and thicknesses and placenta weight at delivery. The maternal basic status was also concluded in the study. Results Correlation analysis results: (1) The transformed placenta volume MOM showed a significant correlation (Spearman rho=0.200, P<0.05) with birthweight but not with placenta weight or placenta volume calculated as ellipsoid (Spearman rho=0.164, 0.112 respectively, P>0.05). (2) The birthweight showed significant correlations with placenta weight, placecnta volume and maternal BMI (Spearman rho=0.478, 0.361, 0.259 respectively, P<0.01). (3) The placenta weight at birth showed a significant correlation with placenta volume at birth (Spearman rho=0.467, P<0.01) and maternal BMI (Spearman rho=0.198, P<0.05). Regression analysis results: (1) Birth weight (g)=1136.9+1530.9×MOM+45.3×BMI-15.0×maternal age (r=0.29, P=0.01<0.05). (2) Placenta weight (g)=88.1+315.3×MOM+10.0×BMI+0.1×maternal age (r=0.27, P=0.02 <0.05). Conclusions The placental volume at 11-13+6 weeks of gestation has significant correlation with birthweight. This might assist in the identification of the high risk pregnancies caring large or low for gestational age fetuses.
