Practical teaching of medical ethics is the key point in judging the effectiveness of the course.After 27 years of teaching efforts and exploration,the teaching of medical ethics in our college has gradually formed the basic form of practical teaching,such as case teaching,group discussion,scientific research activities,case assessment,the combination of medical ethics teachers and clinical teachers in the teaching process.But more attention and efforts are still needed in the following issues,including building a scientific evaluation system for the course of medical ethics,focusing on the continuity of practical and systematic teaching,dedicated practice of medical ethics course,and handling new arising problems in modern medical and healthcare practice.

Objective DNA replication increases during tumor cells limitlessly proliferate. To develop a method that can early diagnose and routine screen out bladder cancer, but it does not impair patients by detecting cdc6 in exfoliate cell in urine of patients with bladder cancer. Methods 200 ml fresh urine of patients with bladder cancer or non bladder cancer who voided urine after morning was collected and centrifugated for urine sediment, then total RNA was extracted with TRIZOL reagent from it and detected the expression of cdc6 gene by RT PCR. Results 28 samples were positive and 2 samples were negative in 30samples of bladder cancer, positive rate was 93.3%. Positive rate was 16.7% in 30 samples of non bladder cancer. Compared with the sensitivity of urine cytology, that of cdc6 RT PCR increases markedly ( P

Objective:To set up the HPLC fingerprints of Scutellaria baicalensis collected from different regions and develop a HPLC method for the quantitative analysis of the chief Flavonoids in Scutellaria baicalensis.Methods:The HPLC separation was performed on SHIMADZU VP-ODS column(250mm?4.6mm,5?m),gradient eluted using 0.1% citric acid-acetonitrile solvent system and detected at 276nm and 200nm to 400nm with a DAD detector.The flow rate was 1.0ml/min.The fingerprints of different samples were compared with similarity evaluation software.Results The HPLC fingerprints of Scutellaria baicalensis was set up,in the fingerprints,17common peaks of flavonoids were confi rmed.But the contents of the chief Flavonoids had a big difference,in which the baicalin had the biggest content(18.32%) in cottage Scutellaria baicalensis of Yiyuan County;the baicalein and wogonin had the biggest content(2.31%&0.73%) in wild Scutellaria baicalensis of Northeastern China.Conclusion:This method showed high precision,good repeatability,stability and all of the content were separated well,so it can be useful as the means to assess the quality of Scutellaria baicalensis.

Objective To explore the bone mineral density (BMD) status and its influencing factors in schizophrenia patients in order to provide basis for risk assessment in psychiatric nursing.Methods A total of 1,139 hospitalized schizophrenia patients were recruited and assigned into the medication group (n=652) and the non-medication group (n=487) according to previous antipsychotic drug history.T-score and Z-score of BMD were determined using Sunlight Omnisense 7000S Bone Densitometry.Blood calcium,blood phosphorus and serum prolactin levels were measured using fasting blood of ulnar vein.Results Differences in age,BMD,milk intake,level of activity,level of smoking,history of fall,history of fracture,serum Ca2+ and PRL were statistically significant between two groups(P<0.05);there were significant differences in BMD rank distributions among schizophrenia patients with different courses of disease and lengths of taking antipsychotics (P<0.001);multiple linear regression showed that influencing factors of BMD with statistical significance were courses of disease,lengths of taking antipsychotics,serum Ca2+,serum PRL,milk intake,level of activity,and level of smoking.Conclusion The BMD was lower in the medication group than that in the non-medication group,and the development of osteoporosis was correlated to various factors.Clinical nurses should master high-risk factors thoroughly and adopt intervention measures in a timely manner.

Object To study the chemical constituents of Dracaena cochinchinensis (Lour.) S. C. Chen. Methods The constituents were isolated on silica gel chromatography, preparative TLC, and spectral data. Results Six compounds were isolated and identified from the resin of D. cochinchinensis as: 1, 2, 4, 5-tetrachloro-3, 6-dimethoxybenzene (Ⅰ), cholest-4?-methyl-7-en-3?-ol (Ⅱ), cholest-4?-methyl-7-en-3-one (Ⅲ), hexacosane (Ⅳ), cholest-7-en-3?-ol (Ⅴ), cholest-7-en-3-one (Ⅵ). Conclusion Compounds Ⅳ-Ⅵ were isolated from D. cochinchinensis for the first time.

Objective To investigate the effect of maternal deprivation (MD) on neurobehavior and PP1Cγgene expression in hippocampus. Methods Male pups were randomly divided into MD group(thirty-five)and control group(twenty-four). From PND 1 to PND 21 ,pups in the MD groups underwent daily maternal deprivation for 3 h ( Postnatal day). Neurobehavior was observed to investigate neurodevelopment, Morris water maze was used to measure spatial learning and memory,and Real-Time quantitative PCR was employed to analyze PP1Cγ gene expression. Results Several significant deficiencies were observed in bodyweight and grasping reflex while a great enhancement in hot-plate test in rat pups suffering from MD( (26.23 ± 2.81 )g vs. (30. 38 ± 3.85 )g;( 19.37 ± 11.89) s vs. (22.39 ± 17.62 ) s; (4.36 ± 1.76 ) s vs. ( 5.26 ± 2.55 ) s; P < 0. 05 ), but deficiencies in neurological reflexes were subtle ( ( 0.83 ±- 0.30 ) s vs. ( 0. 83 ± 0. 34 ) s; ( 3.68 ± 1.63 ) s vs. ( 5.61 ± 3. 01 ) s;( 3.00 ± 0.00 ) vs. ( 3.00 ± 0. 00); P > 0. 05 ). MD had a subtle influence on spatial learning and memory (P >0.05). Meanwhile,MD could lead to PP1Cγ expression down-regulation on PND 22 ( (2.19 ±0.62) vs. (3.52 ±0.86), P<0. 05)which was in line with early neurobehavior results. No difference was found compared with MD group and control group on PND60 ( ( 1.73 ± 0. 78 ) vs. ( 1.33 ± 0. 34); P > 0.05 ). However, there was the up-regulation of PP1Cγexpression on PND 90 ( (2.85 ± 0. 34) vs. ( 1.34 ± 0.93 ); P < 0.05 ). Conclusion MD alters early neurobehavior and hippocampal PP1Cγgene expression in the Wistar rats,but has a subtle effect on learning and memory. At the same time,MD can make PP1Cγexpression in the hippocampus varying with the age.

[Summary] Microcephalic or Majewski's osteodysplastic primordial dwarfism type Ⅱ ( MOPD Ⅱ) is an extremely rare genetic disease mainly caused by pericentrin ( PCNT) gene mutations. This paper reported one 13-year-old boy, who was admitted because of the slow growth for more than 13 years and deepened skin color over six months. He was diagnosed as MOPD Ⅱ associated with a combination of growth hormone deficiency, type 2 diabetes, hypertension, acanthosis nigricans, multiple café-au-lait spots. On magnetic resonance imaging of brain, no vascular malformations such as aneurysms were shown. There were novel compound heterozygous mutations of PCNT gene in the patient, with the nonsense mutations of c. 502C > T ( p. Gln168 * heterozygous variation) and c. 3103C > T (p. Arg1035* heterozygous variation). His father carried a nonsense mutation c. 3103C > T ( p. Arg1035 *heterozygous variation ) and his mother had a nonsense mutation c. 502C > T ( p. Gln168 * heterozygous variation). After treatment with metformin for three months, his blood glucose returned to normal, and acanthosis nigricans was improved. It seems critical to evaluate the abnormal condition of blood vessels regularly for MOPD Ⅱpatients with PCNT gene mutations.

Objective To study the expression of MCM5 gene in urine exfoliate cell and bladder cancer tissue in order to research the diagnosis and difference. Methods We collected the samples of urine exfoliate cell and bladder cancer tissue and extracted the total RNA, and then did RT-nest-PCR, immunohistology to check the expressive level of mcm5 gene. Results Sensitivities of that are 93。3% in 30 bladder cancer, 13。3% in other patients and 0% in normal person. The expression of mcm5 between G1?G2 and G3 bladder cancer tissue have very marked statistic significance ( P
