The estimation of chronologic age based on the stages of third-molar development was evaluated by using the eight stages (A-H) method of Demirjian and the third-molar development was compared, in terms of sex and age, with results of previous studies. The samples consisted of 291 orthopantomograms from young Chinese subjects of known chronologic age and sex (including 139 males with a mean age of 14.67+/-3.62 y and 152 females with a mean age of 14.85+/-3.70 y). Statistical analysis was performed by employing the Mann-Whitney U-test and the t-test. Regression analysis was conducted to obtain regression formulas for calculating dental age from the chronologic age. Our results showed statistically significant differences (P<0.05) in third-molar development between males and females, at the calcification stages D, E and H. And a strong correlation was found between age and third-molar development in both males (r (2)=0.65) and females (r (2)=0.61). New equations (Age=8.76+1.32 Development stage) for estimating chronologic age were derived. It is concluded that third-molar genesis took place earlier in males than in females. The use of third molars as a developmental marker is appropriate in young adults of Central China. The formula obtained in the present study can be used as a guide for estimation of dental maturity and a standard for age estimation for young adults of Central China.

Objective To investigatethe changes of serum IL-12 level and Th balance of chronic hepatitis B (CHB) patients in the course of lamivudine therapy and the related significance. Methods According to the differ ent responses to lamivudine therapy, patients were divided into three groups: group I ( n = 10), HBeAg positive CHB and complete response group; group Ⅱ (n = 10), HBeAg positive CHB and non-complete response group;group Ⅲ ( n = 5), HBeAg negative CHB group. Sera were collected from patients with chronic hepatitis B before and after lamivudine therapy and healthy blood donors. Then serum IL-12, IFN?, and IL-4 levels were measured by ELISA method. The ratio of IFN?/IL-4 was selected as the marker of Th balance after comparison with that of the normal control. Results Before therapy, serum IL-12 level in chronic hepatitis B patients was lower than that of the healthy blood donors, and Th balance tendency was to Th2 direction. After lamivudine therapy, serum IL-12 level was increased. The highest point of IL-12 was observed in complete response group at the third month after therapy.The tendency of Th balance was to Th 1 direction in complete response group and to Th 2 direction in non-complete response group and HBeAg negative group. Conclusion After lamivudine therapy, the immunity response to HBV of chronic hepatitis B patients can be recovered. The response degree to therapy is associated with the level of serum IL-l2 and Th balance recovery level after lamivudine therapy. Serum IL-12 level may be an appropriable marker to predict the effect of lamivudine therapy in earlier period of the whole course. The recovery of Th balance is the assurance of complete response.

Objective To study the probability of using hepatitis D virus (HDV) ribozyme as a kind of anti-hepatitis-C-virus (HCV) gene thera-py drugs. Methods The natural HDV genomic ribozyme′s stem Ⅳ was optimized and its substrate-binding region reconstructed, thus three recombinant HCV-specific HDV genomic ribozymes RzC1, RzC2 and RzC3 were obtained. HCV RNA 5'-noncoding region and 5'-fragment of C region (HCV RNA5'-NCR-C) were transcribed from plasmid pHCV-neo by T7 phage RNA polymerase in vitro, and radiolabelled at its 5'-end. The trans-cleaving reaction was performed by mixing the ribozymes and substrate at mol ratio 100∶1 under conditions as follows: 37℃, pH7.5, Mg2+ 20 mmol/L and deionized formamide 2.5 mol/L. Percentage of trans-cleaved products were calculated at different time points and used as the activity indicator of the three ribozymes. Results RzC1, RzC2 trans-cleaved more substrate when the time extended, and got to 24.9%,20.3% after reac-ting for 90 minutes respectively; RzC3 was not able to trans-cleave its substrate. Conclusion Recombinant HDV genomic ribozymes have the ability to trans-cleave HCV RNA, but the appropriate target sequence should be selected.

Objective Acquiring genetic information of Y-SNPs and Y-STRs genetic makers from samples with the surname of Kong, which is useful for exploring the correlation between surname and Y chromosome in forensic applications studies.Methods Two multiplex genotyping assays and SNaPshot assay were used to analyze 255 unrelated male blood samples who share the same surname Kong and 330 unrelated male blood samples obtained randomly. 17 Y-STRs were typed for the surname Kong population samples. The software Arlequin 3.5.1.2 and the program Network 4.6.1.1 were used for data statistical analysis.Results 13 haplogroups were observed. The highest haplogroup frequency in the two populations were O3a2c1a-M117 (21.57%, 14.85%). 196 haplotypes in Kong population deifned by 17 Y-STRs locus were obtained and the haplotype diversity was 0.9939. 14-12-25-28-19-15-12-19-12-11-12-22-12-11-14-10-19 is the typical haplotype. Median Joining algorithm and Mismatch Distribution were adopted to analyze the Y-STR haplotye under haplogroup O3-M122, and the result shows that there are two “central star” distribution. Conclusion Combined with Y-SNP and Y-STR analysis showed that the Kong population had experienced complicated exchanges and expansion or continued growth, which has more than one surname origin. Hence, its population genetic structure and historical differences have potential applications in forensic science.

OBJECTIVETo assess the association of 8 single nucleotide polymorphisms (SNPs) from chromosomes X and 20 with androgenetic alopecia among ethnic Han population from Yunnan province.
METHODSAn eight-SNP co-amplification protocol was developed for the genotyping with a SNaPshot platform. A case-control study was carried out for the 8 SNPs from chromosomes X and 20 in 115 androgenetic alopecia cases and 125 healthy controls. Statistical analysis was conducted with SPSS17.0, Haploview4.2, SHEsis and MDR software.
RESULTSNo association was found between the two groups with regard to the 4 SNPs located on the X chromosome. The genotypic frequencies of rs2180439, rs913063 and rs1160312 were significantly different between the two groups (P < 0.05). The frequency of T allele of rs2180439 was significantly higher in the case group (P < 0.05). The frequencies of A alleles of rs913063 and rs1160312 were significantly higher in the case group (P < 0.05). The haplotypes of C-T-C-G, T-C-C-G and T-T-A-A based on rs6137444-rs2180439-rs913063-rs1160312 showed significant difference between the two groups (P <0.05). rs6137444, rs21804393 and rs1160312 have a strong association with androgenetic alopecia.
CONCLUSIONThe 4 SNPs located on chromosome X were all monomorphic among ethnic Hans from Yunnan. The rs6152, rs16990427, rs1352015, rs1385699 SNPs located on chromosome 20 are associated with androgenetic alopecia in the same population. Individuals with T allele of rs2180439 and A allele of rs913063 and rs1160312 are more likely to develop androgenetic alopecia.

Background:
Clinical dexamethasone (DEX) treatment or stress in bovines results in extensive physiological changes with prominent hyperglycemia and neutrophils dysfunction.
Objectives:
To elucidate the effects of DEX treatment in vivo on cellular energy status and the underlying mechanism in circulating neutrophils.
Methods:
We selected eight-month-old male bovines and injected DEX for 3 consecutive days (1 time/d). The levels of glucose, total protein (TP), total cholesterol (TC), and the proinflammatory cytokines interleukin (IL)-1β, IL-6 and tumor necrosis factor (TNF)-α in blood were examined, and we then detected glycogen and adenosine triphosphate (ATP) content, phosphofructosekinase-1 (PFK1) and glucose-6-phosphate dehydrogenase (G6PDH) activity, glucose transporter (GLUT)1, GLUT4, sodium/glucose cotransporter (SGLT)1 and citrate synthase (CS) protein expression and autophagy levels in circulating neutrophils.
Results:
DEX injection markedly increased blood glucose, TP and TC levels, the Ca 2+ /P 5+ ratio and the neutrophil/lymphocyte ratio and significantly decreased blood IL-1β, IL-6 and TNF-α levels. Particularly in neutrophils, DEX injection inhibited p65-NFκB activation and elevated glycogen and ATP contents and SGLT1, GLUT1 and GR expression while inhibiting PFK1 activity, enhancing G6PDH activity and CS expression and lowering cell autophagy levels.
Conclusions
DEX induced neutrophils glucose uptake by enhancing SGLT1 and GLUT1 expression and the transformation of energy metabolism from glycolysis to pentose phosphate pathway (PPP)-tricarboxylic acid (TCA) cycle. This finding gives us a new perspective on deeper understanding of clinical anti-inflammatory effects of DEX on bovine.
