OBJECTIVETo observe the effect of Polygonatum sibiricum on Yin deficiency model rats induced by long-term overload swimming.

METHODExcept for the normal group, all of the remaining rats performed the long-term overload swimming for eight weeks, with five days every week and once every day, to establish the Yin deficiency model. The daily swimming time increased from 10 min to 180 min at the end of the 7th week, with the water depth of 60 cm and the water temperature at 30 degrees C. After the success of the modeling, the rats were orally administered with different doses of aqueous extracts from P. sibiricum (2.5, 10 g x kg(-1)) for eight weeks. After the final administration, their blood were collected from orbits to measure immunoglobulin A, G and M (IgA, IgG, IgM), interleukin 2 and 6 (IL-2, IL-6) and cAMP, cGMP contents in plasma General behavioral indicators (weight, facial temperature, pain threshold and holding power) of rats were observed during the drug administration.

RESULTCompared with the model control group, aqueous extracts from P. sibiricum was given for eight weeks to significantly increase the rat weight and holding power of Yin deficiency model rats, decrease the facial temperature and the sensitivity of pain threshold, and increase IgA, IgG, IgM and IL-6 content and IgG content in serum, but without statistical difference. Aqueous extracts from P. sibiricum (10 g x kg(-1)) could also increase IL-2 content in serum, and decrease cAMP content and cAMP/cGMP ratio.

CONCLUSIONP. sibiricum could improve the general behavioral indicators (weight, holding power, pain threshold and facial temperature), immunologic functions (IgA, IgG, IgM) and cyclic nucleotide (cAMP, cAMP/cGMP), so as to ameliorate such Yin deficiency symptoms as dysphoria in chestpalms-soles, weight loss, soreness and weakness of waist and knees, immunologic dysfunction and cyclic nucleotide system disorders.

OBJECTIVE: To investigate genetic polymorphisms of 21 non-CODIS STR loci in Han population from the east of China and to explore their forensic application value. METHODS: Twenty-one non-CODIS STR loci, were amplified with AGCU 21+1 STR kit and DNA samples were obtained from 225 unrelated individuals of the Han population from the east of China. The PCR products were analyzed with 3130 Genetic Analyzer and genotyped with GeneMapper ID v3.2 software. The genetic data were statistically analyzed with PowerStats v12.xls and Cervus 2.0 software. RESULTS: The distributions of 21 non-CODIS STR loci satisfied the Hardy-Weinberg equilibration. The heterozygosity (H) distributions were 0.596-0.804, the discrimination power (DP) were 0.764-0.948, the probability of exclusion of duo-testing (PEduo) were 0.176-0.492, the probability of exclusion of trios-testing (PEtrio) were 0.334-0.663, and the polymorphic information content (PIC) were 0.522-0.807. The cumulative probability of exclusion (CPE) of duo-testing was 0.999707, the CPE of trios-testing was 0.9999994, and the cumulated discrimination power (CDP) was 0.99999999999999999994. CONCLUSION Twenty-one non-CODIS STR loci are highly polymorphic. They can be effectively used in personal identification and paternity testing in trios cases. They can also be used as supplement in the difficult cases of diad paternity testing.

OBJECTIVETo obtain streptavidin-tagged human interleukin-15 (SA/hIL15) fusion protein and evaluate its bioactivity.

METHODSpET24a-6His-SA-hIL-15 and pET32a-hIL-15-SA-6His plasmids were constructed and expressed in BL 21(DE3) host bacteria to generate the fusion protein. The recombinant fusion protein IL-15/SA was purified using Ni-NTA affinity chromatography and refolded, and the efficiency of surface modification of the fusion protein on biotinylated cells was examined by fluorescence-activated cell sorting. CCK-8 method was used to evaluate the effect of IL-15/SA fusion protein in inducing the proliferation of human peripheral-blood lymphocyte (PBL) cells stimulated by PHA.

RESULTSThe recombinant SA-hIL-15 and hIL15-SA fusion proteins were highly expressed in BL21(DE3) at about 20% of the total bacterial proteins. The purified hIL15-SA fusion protein exhibited a bifunctionality by promoting the proliferation of PBL cells activated by PHA and high-affinity binding to biotinylated cell surface mediated by SA, with a cell surface modification efficiency exceeding 95%. SA-hIL-15 showed a 4-fold higher hIL15 bioactivity than hIL15-SA.

CONCLUSIONSA/hIL-15 bifunctional fusion protein has been successfully obtained to facilitate the future development of hIL-15-surface-modified cancer cell vaccine.

OBJECTIVETo explore the treatment plan in patients with congenital lower incisor missing.

METHODSThirty-six patients with congenital lower incisor missing were included in the investigation. The missing location, missing quantity, malocclusion type and treatment method were analyzed. Bolton index of two groups were analyzed. The first group was congenital missing one lower incisor who treated by extracting two upper first premolars and one lower first premolar. The second group was congenital missing two lower incisors who treated by exacting two upper first premolars.

RESULTSThe therapeutic effect of 36 cases were better. Overall ratio in two groups were 91.70% +/- 1.85% and 92.83% +/- 2.74%, anterior ratio were 81.69% +/- 2.12% and 85.46% +/- 2.39%, anterior tooth-size discrepancy were (2.16 +/- 0.64) mm and (4.27 +/- 1.14) mm. There were no significance difference on overall ratio in two groups (P > 0.05). There were significance difference in anterior ratio and anterior tooth-size discrepancy (P < 0.01).

CONCLUSIONFor patients with congenital missing one lower incisor who need extraction in upper and lower jaws, it is less affection on Bolton index that extracting one premolar at non-missing side than extracting one center incisor in mandible.

OBJECTIVETo study the genetic basis in the patients with clinical diagnosis of spinal muscular atrophy(SMA) but without survival motor neuron telomeric copy (SMN-T) deletion; the relationship between the SMN-C (centromeric) copies and the phenotype; and the distribution of SMN-C and SMN-T copies in the SMA patients, the carriers and the controls.

METHODSQuantitative PCR analysis of SMN-T and SMN-C copies were carried out in 45 patients, 25 consanguineous and 33 control individuals. The patients were identified by clinical manifestation and muscular pathology. Two internal standards of SMN-T and cystic fibrosis transmembrane conductance regulator (CFTR) were constructed. Nonradioactive and nonfluorescence-labelling competitive PCR were used. The numbers of SMN-T and SMN-C copies were determined by calculating the ratios of SMN-T/CFTR and SMN-C/CFTR.

RESULTSQuantitation of SMN-T gene copies in SMA patients revealed that nine cases of type I-III were homozygously deleted. Two cases of type III had only one copy and four cases of type III had two copies. SMA IV and other type cases had two copies. Nine cases of consanguineous individuals had one copy, but other 16 had two copies. All of the normal individuals had two copies. Analysis of SMN-C copies showed that SMA I had < or = 2 copies, II-III had < or = 3 copies, SMA IV and others had 0-3 copies, the consanguineous individuals and normal individuals had 0-3 copies.

CONCLUSIONThe number of copies determined by PCR quantitative assay of SMN-T is in accordance with the result of PCR qualitative assay of homozygous deletion. Quantitative assay of the number of copies can find out the cases and the carriers of heterozygous deletion. The SMA phenotype is related to the number of copies of SMN-C; the smaller the number of copies the patient has, the severer the patient's phenotype will be. The pathogenesis of SMA IV and other types of SMA may not relate to SMN gene.
