Objective To explore the criminological characteristics and appraisal traits of capacity for responsibility in murder by patients with mental retardation and schizophrenics. Methods 20 cases who were appraised as mental retardation and 58 ones as schizophrenics were retrospectively compared. Results They were similar in gender, age, occupation, casualty and criminal plan , but different in criminal motives, criminal targets, action after crimes, repeated crimes. Conclusion The irritability mental retardation patients and schizophrenics with delusion of persecution or jealousy would be warded strictly. The criminological characteristics is helpful to assess the capacity for responsibility as well as differential diagnose mental retardation and schizophrenics.

ObjectiveTo investigate the role and clinical significance of interferon regulatory factor 7 (IRF7) and Toll-like receptor 9 (TLR9) in the development of condyloma acuminatum (CA).MethodsReverse transcription-PCR was performed to analyze the mRNA expressions of IRF7 and TLR9 in peripheral blood mononuclear cells(PBMCs) of 25 patients with CA and 20 normal human controls.ResultsThe expression levels of IRF7 and TLR9 mRNA in PBMCs were significantly higher in the patients with CA than in the controls(both P ＜ 0.01 ).Conclusion There is a significant increase in the expression of IRF7 and TLR9 in the PBMCs of patients with CA.

AIM:To demonstate the expression of human cytochrome P450 3A4 isozyme in the transgenic cell line CHL - 3A4 established in this laboratory. METHODS:Nifedipine (NIF) can induce the reversal of the brug resistance for adriamycin of multidrug resistant(MDR) cell K562r. The NIF is the specific substlate for CYP3A4. To determine the NIF oxidase activity of the transgenic CHL - 3A4 cells by comparing the biological effect of NIF, which preinculbated with or without CHL - 3A4 S9 mix. RESULTS: When the multidrug resistance cell K562r was cultured in medium with NIF (12. 5 ?g? L- 1 ), a calcium channel blocker and specific substrate for CYP3A, it's IC50 for adri- amycin declined from(6.47?0.60) mg ? L- 1 to (0. 89?0. 15) mg? L-1. When cells were cultured in NIF(exactly the same concentration ) pretreated with CHL - 3A4 S9 mix,no reversal of MDR was observed [IC50 for adriamycin is (6.10?0.50) mg? L-1 ] while if NIF was pretreated with CHL S9 or inactivated CHL - 3A4 S9 mix, its biological effect was not deteriorated [IC50 for adriamycin is (0. 32?0.90) and (0.32?0.04) mg?L-1, P

Objective To investigate the clinical features of anuria caused by pediatric congenital bilateral ureteral stenotic obstruction,and to improve the diagnosis and treatment of the disease.Methods This series included 7 infants(2 males and 5 females;age range,35-57 d) with congenital bilateral ureteral stenotic obstruction.The clinical presentations were characterized by sudden anuria or oliguria.B-ultrasound,cystography and puncture pyelography were performed in all of them,and magnetic resonance urography(MRU) in 3.Based on the definite diagnosis,resection of stenotic segment of the ureter or ureteral implantation was performed on them.Results The diagnosis was confirmed by puncture pyelography in all of the 7 cases.Six cases underwent phase I surgery and recovered.No ureteral stenosis and cystoureteral reflux occurred during a follow-up of 2-4 years.The renal function was normalized in them.One case had stenosis recurrence due to scar formation,and was cured by the second operation.Conclusions Anuria caused by pediatric congenital bilateral ureteral stenosis should be diagnosed and treated as early as possible.Definite diagnosis can be established by puncture pyelography and MRU.Resection of the obstructive segment of the ureter,protection of renal function,and ureteral implantation are the main therapies.

Objective To investigate and compare the argumentativeness and attitudes towards thinking and learning between clinical nurses in general adult wards and wards for patients requiring particularity healthcare for the identification and development of core communication skills.Mettods “Argumentativeness Scale” and “Attitudes toward Thinking and Learning Survey” in Chinese were used to measure a convenience sample of 504 clinical nurses in seven hospitals.Results The scores in items reflecting rationality,positivism,empathy and acceptance in 247 nurses in wards for particularity heahhcare were significantly different from those nurses working in internal medical wards for adults with internal medical problems.Conclusions To develop harmonious interpersonal relationships in nurses,we should strengthen competencies in emotional regulation and rational thinking in nurses in wards for adults with in-ternal medical problems.

AIM: To study the expression and its kinetics of rice phenylalanine ammonia-lyase gene encoding into E. coli as the basis of treatment for phenylketouria. METHODS: The phenylalanine ammonia-lyase-1-cDNA(rPAL-1-cDNA) from rice was recombined into E. coli high expression vector pET-28c and transformed into E. coli host strain BL21DE3. Engineering bacteria was then inducted by isopropyl-?-D-thiogalactoside (IPTG) for 1, 3, 5, 7 hours, in order to obtain high level expression. RESULTS: After induction, the expression level of fusion protein was 21.40%, 30.60%, 35.40%, 35.43% respectively. The fusion protein exhibited a band of 78 6 kD on SDS-PAGE analysis,but was not found in controls.The target protein was mainly existed in the form of inclusion body. CONCLUSION:Rice PAL gene expressing E. coli was established by gentic engineering technique.

AIM:To clon human cytochrome P450 2A6 cDNA. METHODS:Using reverse transcription polymerase chain reaction(RT-PCR) and DNA recombinant technique, a full-length cDNA encoding cytochrome P450 2A6( CYP2A6 ) from human liver was cloned into pBluescript vector. The cDNA segment was identified by DNA sequencing.RESULTS: Comparing with the CYP2A6 sequence, the cloned CYP2A6 cDNA had two different bases, codon 8 CTG(Leu)→TTG(Leu), codon 479 GGC(Gly)→GTC(Val) and was quite different in their 3′end noncoding region. Comparing with CYP2A7 seqence reported by Fernandez-Salguero,the cloned CYP2A6 cDNA had some different in 5′ end coding sequence and several differencey in the 3′ end coding and noncoding sequence, but both codon 479 were GTC(Val).Comparing with the CYP2A7 seqence reported by Yamano,the cloned CYP2A6 cDNA had some difference in the coding sequence but the 3′ end no-coding area was the same. CONCLUSION: The cloned cDNA was a new cDNA of CYP2A6 which may be transcripted from a new allele of CYP2A6.

Objective To evaluate the changes of left ventricular regional function in normal subjects with aging and the influencing factors by Doppler tissue imaging. Methods One hundred and twelve normal subjects were divided into four groups according to age: I group with age≤18 years old ; II group with 18 60 years old. Using a quantitative tissue velocity analysis system and tissue tracking, the peak velocities of different ventricular segments at systole, early and late diastole (Vs, Ve,Va) , the Ve/Va ratios were obtained and the effects of age, gender, heart rate and STd were analyzed. Results (1) Peak velocities of different segments of each wall were decreased one by one from mitral annulus, the basal, middle segment to the apical portion. (2) Peak velocities of different ventricular walls were significantly different, with the antero- and posterio-inter-ventricular septum being the lowest CVe (6. 89?2. 60) ,(7. 94?2. 64)cm/s]and with the latero-,posterio-,antero, and inferior walls of the left ventricle being higherCVe (9. 85?3. 02) , (9. 80?3. 09), (8. 86?3. 16), (8. 23?2. 48) cm/s] . (3) Peak velocities of different segments were associated with age, STd, BMI, heart rate and not associated with gender. (4) The Ve/Va ratios were increased one by one from mitral annulus, basal, middle segment to apical portion, and were significantly lower in III group and IV group than in I group and II group. Conclusions Peak velocities of different segments at different walls change regularly and age is the most important influencing factor to the diastolic velocities.

Objective To compare the effects of health education on fat intake behavior and its psychology in students with different BMI,provide evidence for improving individual healthy education.Methods A experimental epidemiology was used,Twenty-nine secondary school classes were randomly selected by multi-stage cluster sampling from two cities in Zhejiang province.Overweight or obesity group included all students who were judged overweight or obesity,normal group included students who were judged normal and basic matched by age,grade,sex and stage of baseline.Intervention based on transtheoretical mode was conducted on two groups and intervention results were measured by the adolescent fat intake behavior of psychological measurement scales (Chinese version).Chi-square tests,T-tests,non-parameters tests and binary logistic regression were performed for data analyses.Results Stage of students with overweight or obesity and with normal BMI all moved forward after intervention,while the proportion of stage advance for students with overweight or obesity was further than students with normal BMI.Change strategy(2.60±0.79),pros(3.58±0.90) and self-efficacy(3.01±0.72) of students with overweight or obesity better than students with normal BMI in baseline((2.34±0.86),(3.08±0.91),(2.79±0.81)) while difference was not significant after intervention.Logistic regression analysis discovered that the promotion of change strategy moved stage forward for students with normal BMI(OR=2.168,95％ CI:1.560-3.014)and promotion of self-efficiency moved stage forward for students with overweight or obesity (OR=1.801,95％ CI:1.026-3.159).Conclusion The intensity and duration of psychological intervention is essential to be reinforced for students with normal BMI,while for students with overweight and obesity,psychological intervention should be promoted in combination with social support.

Objective To investigate the osteogenic potential for size-critical bone defect of fibrin sealant combined with recombined human bone morphogenetic protein-2 (rhBMP-2) grafting and varied autologous bone marrow mesenchymal stem cells (BMSCs) implanting in vivo. Methods BMSCs were cultured and induced with osteogenic supplement (OS) medium. BMSCs with and without OS induction were collected and percutaneously autologous injected respectively into the 15 mm bone defect of experimental rabbit model. The grafts were BMSCs, osteo-induced BMSCs, BMSCs and osteo-induced BMSCs, BMP combined with fibrin sealant, 0.9% NaCl solution.
