OBJECTIVETo discuss the TCM pattern classification and measurable diagnosis criterion of the protracted symptoms of heroin-addiction abstinence (PSHAA).

METHODSThrough literature review and clinical study, the concept of TCM patterns and diagnostic standard were established, and a TCM pattern scale for quantitatively analysis of PSHAA was formulated. The scale were used on the clinical investigation on the abuser for 5 times on day 15, 30, 60, 90 and 120 after abstinence. Then the TCM patterns of PSHAA was classified using methods of DME and quantitative diagnosis, to create a corresponding scale of diagnostic indexes referring maximum likelihood method.

RESULTS(1) The TCM patterns of PSHAA commonly seen were Toxin-stasis accumulation (TSA) with Qi-blood insufficiency, TSA with Qi-yin deficiency, TSA with Yin-deficiency and Fire-excess and TSA with Yin-Yang deficiency. (2) The retrospective and prospective verification of the scale of diagnostic indexes showed it has high sensitivity and speciality, with low rates of misdiagnosis and of missed diagnosis.

CONCLUSIONIt is feasible to develop measurable diagnosis on the TCM patterns of PASAA using DME method and measurable diagnostic methods. The scale of diagnostic indexes formulated with the maximum likelihood method of quantified diagnosis has a certain clinical practicability.

To develop and validate a novel 6-dye STR(short tandem repeat) 25-plex DNA typing system for forensic DNA profiling and databases. In this study, a novel STR 25-plex DNA typing system that includes 24 autosomal STRs (D1S1656, D2S1338, D2S441, D3S1358, D5S818, D6S1043, D7S820, D8S1179, D10S1248, D12S391, D13S317, D16S539, D18S51, D19S433, D21S11, D22S1045, CSF1PO, FGA, Penta D, Penta E, TH01, TPOX, vWA, D11S4463) and Amelogenin was developed. Validation studies demonstrated the sensitivity, accuracy, and reproducibility of our novel STR 25-plex DNA typing system. The sensitivity of the STR 25-plex DNA typing system was demonstrated by the ability to obtain complete profiles from as little as 0.125ng of human DNA. Specificity testing was demonstrated by the lack of cross-reactivity to a variety of commonly encountered animal species and microbial pool. For stability testing, full profiles were obtained with humic acid concentration ≤60ng/μL and hematin ≤600μM. For forensic evaluation, the selected 24 autosomal STRs followed the Hardy–Weinberg equilibrium. Since 24 autosomal STRs were independent from one another, PM (Probability matching) was 3.5434×10-28, TDP (Total Probability of Discrimination Power) was 0.999999999999999999999999969863, and CEP (Cumulative probability of exclusion) was 0.99999999375. The new STR 25-plex typing system is sensitive, reproducible, and stable, therefore it is highly applicable for use in national DNA database and can help to facilitate international data sharing.

Objective To investigate the possible role of plasma leptin and total cholesterol in the pathophysiology of attempted suicide in depressive episode patients. Methods The subjects were 25 depressive episode patients who had recently attempted suicide and 30 depressive episode patients without suicide attempt. The Hamilton Depression Rating Scale-24 items ( HAMD24 ), Beck Helpless Rating Scale (BHS) and Self-rating Idea of Suicide Scale (SIOSS) were used to evaluate the severity of symptoms. In addition, 32 individuals who took part in health examination were selected as health control group. Body height and weight were measured to get body mass index (BMI) of all objects, and plasma leptin and total cholesterol were measured by venous blood before taking pill. Results (1)HAMD score , BHS score and SIOSS score in patients with attempted suicide were higher than patients without suicide (P ＜ 0.01 ). (2) The total cholesterol and plasma leptin in patients with attempted suicide ( (3.3 ±0.9)mmol/L, (6.1 ±3.7)μg/L)were lower than that in patients without suicide( (3.6± 1.2)mmol/L, (9.4 ± 4.4)μg/L; P ＜ 0.05 ～ 0. 0l ), while total cholesterol and leptin in patients without suicide attempt ( (3.6 ± 1.2 ) mmol/L, ( 9.4 ± 4.4 ) μg/L) were lower than that in normal controls ( ( 4.8 ± 0.9 )mmol/L, ( 13.4 ± 6.7 ) μg/L; P ＜ 0.05 ～ 0.01 ). (3) Plasma leptin and total cholesterol of all patients were positively correlated with BMI(P＜0.01 ). Moreover, plasma leptin and total cholesterol in patients with attempted suicide and patients without attempted suicide were inversely positively correlated with HAMD score , BHS score and SIOSS score. Plasma leptin was significantly positively correlated with total cholesterol in patients with attempted suicide and patients without suicide, but there was no significant difference in normal controls(P＞ 0. 05). Conclusion The results suggest that decreased plasma leptin is related to the pathophysiology of attempted suicide in depressive episode patients.

A system coupling ethanol fermentation with microalgae culture was developed, in which CO2 produced during ethanol fermentation was used as carbon source for the growth of Tetraselmis subcordiformis, a microalgae accumulating starch intracellularly. The biomass concentration about 2.0 g DCW/L was achieved within the photobioreactor for the batch culture of 7 days, and intracellular starch accumulation was about 45%. Furthermore, ultrasonic pretreatment and enzymatic hydrolysis were applied to the microalgae biomass, and 71.1% of the intracellular starch was converted into glucose that was fermented sequentially to ethanol by Saccharomyces cerevisiae with an ethanol yield of 87.6% of the theoretical value, indicating that the microalgae biomass could be an alternative feedstock for ethanol production to save grain consumption, and in the meantime mitigate the CO2 emission.

The study is aimed to ensure the quality and safety of medicinal plants by using ITS2 DNA barcode technology to identify Corydalis boweri, Meconopsis horridula and their close related species. The DNA of 13 herb samples including C. boweri and M. horridula from Lhasa of Tibet was extracted, ITS PCR were amplified and sequenced. Both assembled and web downloaded 71 ITS2 sequences were removed of 5. 8S and 28S. Multiple sequence alignment was completed and the intraspecific and interspecific genetic distances were calculated by MEGA 5.0, while the neighbor-joining phylogenetic trees were constructed. We also predicted the ITS2 secondary structure of C. boweri, M. horridula and their close related species. The results showed that ITS2 as DNA barcode was able to identify C. boweri, M. horridula as well as well as their close related species effectively. The established based on ITS2 barcode method provides the regular and safe detection technology for identification of C. boweri, M. horridula and their close related species, adulterants and counterfeits, in order to ensure their quality control, safe medication, reasonable development and utilization.

BACKGROUNDMutations in fumarylacetoacetate hydrolase (FAH) gene can lead to tyrosinemia type 1 (HT1), a relatively rare autosomal recessive disorder. To date, no molecular genetic defects of HT1 in China have been described. We investigated a Chinese family with a HT1 child to identify mutations in FAH.

METHODSDNA sequencing was used for mutations screening in FAH gene. Real-time polymerase chain reaction (PCR) was performed to determine the FAH gene expression level. To confirm the presence of degradation by the nonsense-mediated mRNA decay pathway (NMD), the fragments containing R237X mutations were analyzed by primer introduced restriction analysis-polymerase chain reaction (PIRA-PCR) and cDNA sequencing. Finally, the effects of the mutations reported in this study were predicted by online softwares.

RESULTSA boy aged 3 years and 8 months was diagnosed clinically with HT1 based on his manifestations and biochemical abnormalities. Screening of FAH gene revealed two heterozygous mutations R237X and L375P transmitted from his mother and father respectively. In this pedigree, the amount of FAH mRNA relative to a healthy control was 0.44 for the patient, 0.77 for his mother and 1.07 for his father. Moreover, both PIRA-PCR and cDNA sequencing showed significant reduction of the FAH mRNA with R237X nonsense mutation. The missense mutation of L375P was not reported previously and prediction software showed that this mutation decreased the stability of protein structure and affected protein function.

CONCLUSIONSThis is the first case of HT1 analyzed by molecular genetics in China. The R237X mutation in FAH down- regulates the FAH gene expression, and the L375P mutation perhaps interrupts the secondary structure of FAH protein.
