Schizophrenia is a common but complex mental disorder affected by multiple factors. Forensic psychiatric assessment of schizophrenia involves evaluations on many aspects, but there is no effective biological identification index for schizophrenia. Researches indicate that dysfunction of dopaminergic neurotransmission plays an important role in the pathogenesis of schizophrenia. Our study reviews the classification, genetic structure of dopamine receptors and the recent pertinent studies between the dopamine receptors and schizophrenia and its forensic significance.

The study was undertaken to ascertain the effects of C2 on he- patic lipase(HL), lipoprotein lipase ( LPL ) and plasma lipids. It was found that HDL-c and HDL-c /TC were increased, but(VLDL + LDL)-c and TC were decreased. LPL activety was positively correlated with the increase of HDL-c and the decrease of ( VLDL+LDL )-c.

In the perspective of the theory of intersubjectivity, the educators and the educated in the mental health education of college students establish a subject-subject relationship by experience teach-ing as an intermediary. By focusing on the needs of students, mobilizing the students ' active participation, adopting the experience teaching in small class, the way of formative evaluation, the relationship of mutual integration and mutual promotion are established , which realizes the validity of the College Students ' Mental Health Educationcourse.

Objective To study the genetic polymorphisms of DYF155S1 locus in 107 unrelated individuals both in the Han population, China and the Japanese population. Methods MVR-PCR, automated fluorescence detection and DNA sequence analysis were carried out for studying. Results Five types of repeat unit and one type newly named type 6 which was resulted from the T22A substitution on Type 1 were detected. Type 6 is monopolized by Japanese and may be regarded as a racial characteristic genetic marker. The common arrangement of the repeat units was 3134 which were detected at 73.44 % and 67.44 % in the Han and Japanese populations respectively. The abundance of arrangement of 3134 is the character of yellow race. Next to the arrangement of 3134 was the arrangement of 134 which was detected at 17.19% in the Han population while the arrangement of 6134 was detected at 16.28% in the Japanese population. The average number of type 4 unit at the 3'terminal was 8.8 in the Japanese population much lower than 12.5 in the Han population. Conclusion This study implies that DYF155S1 locus is an important geneticmarker with good genetic polymorphisms. The population difference between the Han and the Janpanes is significant.

Objective To investigate the molecular structure, gene expression and detecting methods of some new variant alleles at FUT2 locus. Method We examined four new variant alleles at FUT2 locus using PCR, RFLPs, gene recombination, DNA sequencing and techniques related to gene expression. Results Three missense gene mutations which were C664T, G868A and G760A respectively were found in three New Guinea individuals. Absence of the glycosyltransferase activity in all three enzymes coded by above three missense gene mutations were confirmed by gene expression techniques. Nonsense mutation A660T was found in one Chinese Han individuals. Changing of sequence of endonuclease SacI resulted from C664T and A660T can be detected by RFLP method. Weak peaks of variats might be missed if DNA sequencing was used to detect heterozygotes. RFLP method can't be used to determine specific site of variation within identified sequence of endonuclease. Conclusion All three FUT2 genes resulted from three mutations C664T, G868A, and G760A were non-secretor genes. More than two methods must be used for checking results each other when detect DNA sequence polymorphisms.

Objective To study the genetic polymorphism and population diversity of three SNP loci and their haplotypes on human Y Chromosome. Methods Genetic polymorphisms, population diversity and hap-lotypes of these SNP loci, M4, M9 and M122, on human Y chromosome, in 140 wnrelated individuals from Zang Nationality in China, Japanese, Negroes and white men from southern Africa were studied by using PCR-RFLPs and DNA sequencing analysis. Results No polymorphism was found on M4 locus, each sample was M4A. All samples were wild type. 3 haplotypes were found. In all Negroes there was a wild haplotype of M4A/M9C/M122T. A haplotype of M4A/M 9G/M122T were found in 8 white men. No M122C gene was found. The haplotypes of M4A/M9C/M122T were mainly found in both Japanese and Chinese, The haplotype frequencies in Japanese and Zang population in china were 0.5 and 0.65 respectively. The probability of discrimination power (DP) and the excluding probability of paternity (EPP) were 0.6191 and 0.4994 respectively and the haplotype of M4A/M9C/M122C was absent. There was a remarkable difference (P

It is unable to cultivate students' ability of application and innovation by the traditional teaching form in pharmaceutics for the pharmaceutics is fragmented and intersective with other disciplines. This paper analyzes the characteristics and shortcomings of traditional teaching methods of pharmaceutics. The flipped classroom is applied to pharmaceutics teaching with SPOC, world coffee and hacker. The results shows that the flipped classroom can effectively improve the motivation and learning efficiency of students, especially improve their self-study and innovation ability. It can realize the diversity of teaching evaluation.

Objective To investigate the changes of autoantibodies in hepatitis B disease and its clinical sig-nificance.Methods 418 cases of hepatitis B patients were selected as hepatitis B group.At the same time,148 hos-pitalized patients in our hospital with autoimmune hepatitis( AIH) were chosen as AIH group.And 100 healthy people with physical examination were selected as control group at the same time .The antinuclear antibodies , anti -smooth muscle antibody( SMA) and anti-kidney microsomal antibodies and other autoantibodies of the three groups were detected and analyzed statistically.Results ANA-positive rate of hepatitis B group was 22.73%,ANA titer was mainly 1:100,only two cases of liver cirrhosis titers were 1:320,ANA karyotype was mainly homogenous,only four cases belonged speckled pattern;ANA positive rate of AIH patients was 60.14%,ANA titer was mainly 1:320,or even 1:1 000, primarily as a spot -type karyotype, nucleolar and centromere type.Differences between the two groups were statistically significant (P<0.05).The positive rates of hepatitis B,chronic hepatitis,severe hepatitis B and hepatitis B patients with cirrhosis ANA were significantly higher than in patients with acute hepatitis B,the differ-ences were statistically significant (χ2 =12.172,12.560,28.123,all P<0.05).Compared with AIH group,the posi-tive rate of SMA and LKM in patients with hepatitis decreased 51.98%,32.22%,respectively,the differences were statistically significant (χ2 =196.843,107.357,all P<0.05).The positive rate of hepatitis B level ANA ( +) patients of ALT and AST,HBV DNA was significantly higher than ANA (-) group.The level of hepatitis B patients ALT and AST,HBV DNA positive group were significantly higher than AIH.Differences were statistically significant (all P<0.05).Conclusion Autoantibody detection helps to study autoimmune etiology and pathogenesis of great importance for patients with hepatitis B and cirrhosis,but the reaction involved in the pathogenesis of autoimmune hepatitis level research still needs to be deeper.

The polymorphisms of the TPOX locus in two population were studied by PCR technique followed by the denatured PAGE and silver staining.Seven alleles were detected in each population of 100 unrelated Northern Chinese Han individuals and 93 unrelated African(Xhosa)individuals in South Africa respectively.No deviation from the Hardy Weinberg equilibrium was demonstrated.The power of discrimination(DP)and the exclusion probability(EPP)were 0 7978 and 0 4625;0 9141 and 0 6125 respectively.Comparison of gene frequency distribution showed that there is significant difference between different races.In addition,three rare genes were detected in we Africans(Xhosa)individuals.Sequencing proved that the only difference among them was the number of repeat unit in the region amplified by the specific primer pair.It might be due to the unequal exchange between chromosomes which was resulting in the production of a chimera.Our study showed that the TPOX locus has a high discriminating power which is important for the study of forensic medicine and human genetics\;

The spceics identification by the hemoglobin band patterns in blood stains using isoelectric focusing with amphotine made in China is reported. Forty different sorts of bloodstain from human and animals were studied. Although the ability of species identification of hemogolbin band patterns in blood stains is lower than those in hemolysates, but the indentification of humen blood stain and the blood stains from most different spcies of animads were achieved. With the exception blood stain indintification between human adult foetus and monkey as well as between five groups in classes of bird and fish Human adult blood stain could be distinguished much easily from animal's blood stains but not from human foetus ,if the blood stairis were pretreated with PCMB. It is concluded that the species indentification of blood staine using isoelectice focusing with ampholinemade in china is possible.
