OBJECTIVETo observe the effect of Qiju Dihuang Pill (QDP) on changes of Chinese medical syndrome types in pregnant women of Gan-Shen yin deficiency syndrome (GSYDS), and to explore the correlation between imbalanced cytokine levels and GSYDS.

METHODSThis was a random controlled trail. A total of 163 pregnant women of GSYDS at 12 -16 gestational weeks were randomly allocated into the experimental group (86 cases) and the control group (77 cases). Patients in the experimental group took QDP for 2 -4 weeks. Changes of Chinese medical syndrome types and serum interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) levels were observed and compared between the two groups before and after treatment.

RESULTS(1) Totally 41 patients (47.7%) in the experimental group were transformed to normal Chinese medical syndrome type. In the same period of the follow-ups, 9 patients (11.7%) in the control group were transformed to normal Chinese medical syndrome type, showing statistical difference (P < 0.05). (2) In the experimental group, the serum level of IFN-gamma and the ratio of IFN-gamma/IL-4 in the peripheral blood were obviously lower after treatment than before treatment (P < 0.01), and obviously lower than those in the control group (P < 0.01). The level of IL-4 after treatment in the experimental group was higher than that before treatment, and also higher than that in the control group, but with no statistical difference.

CONCLUSIONSThese results indicated that there was imbalanced IFN-gamma/IL-4 ratio in the peripheral blood of pregnant women of GSYDS. QDP might play a role in immunoregulation by affecting the IFN-gamma level.

OBJECTIVETo evaluate bi-directional modulation effect of Chinese herbal medicine on immunol cells.

METHODTwo different active portions were isolated from Kudzuvine Root(Radix puerariae), one being the ethanol extraction and another the water extraction. Different concentration of these two different portions was studied by using PMA stimulated lymphocyte or eosinophil initiated chemiluminescence system.

RESULTWater extraction of Kudzuvine Root could enhance chemiluminescence concentration dependently whereas enthanol extraction of Kudzuvine Root inhibited the chemiluminescence significantly.

CONCLUSIONThe bi-directional regulation effect of Chinese herbal medicine can be found in the same herb, because of its efficacy of different active compounds.

OBJECTIVETo explore the correlation between the polymorphism in the DNA methyltransferase-3B (DNMT3B) gene promoter single nucleotide polymorphism (SNP)-149C→T (rs2424913) and-579G→T(rs1569686) and the genetic susceptibility to colorectal cancer in Jiangsu population.

METHODSGenomic DNA was extracted from the leukocyte cell of blood samples collected from 544 colorectal cancer (CRC) patients (including 280 cases of colon cancer and 264 cases of rectal cancer) since January 2009 and July 2010, in a hospital, Jiangsu Province. The same samples were collected from the other 533 control subjects. Polymerase chain reaction with restriction fragment length polymorphism (PCR-RFLP) and DNA sequencing analysis were employed to assess the polymorphism of DNMT3B gene promoter-149C→T and-579G→T.

RESULTSFor DNMT3B-149C→T, no significant deviation was observed in the genotype distributions of polymorphisms between CRC cases (TT: 98.90% (538/544); CT: 1.10% (6/544)) and controls (TT: 97.75% (521/533); CT: 2.25% (12/533)) (χ(2) = 2.07, P = 0.15). The CC genotype was not detected in either patients or control subjects. The DNMT3B-149CT genotype was not associated with the risk of CRC (adjusted OR = 0.48, 95%CI: 0.18 - 1.30). For DNMT3B-579G→T, the genotype distributions of polymorphisms in CRC patients (TT: 90.07% (490/544); GT: 9.19% (50/544); GG: 0.74% (4/544)) were significantly different from those in control group (TT: 81.80% (436/533); GT: 17.82% (95/533); GG: 0.38% (2/533)) (χ(2) = 15.49, P < 0.05). The results showed that the-579 G allele could significantly decrease the risk of CRC (adjusted OR = 0.50, 95%CI: 0.35 - 0.72) in comparison with the -579 TT genotype. In addition, stratification analysis showed that for DNMT3B-579G→T, the genotype distributions of polymorphisms in colon cancer (TT: 92.50% (259/280); GT: 7.50% (21/280)) were significantly different from those in the controls (TT: 81.80% (436/533); GT: 17.82% (95/533); GG: 0.38% (2/533)) (χ(2) = 13.53, P < 0.05); and similar result was found in rectal cancer (TT: 87.50% (231/264); GT: 10.98% (29/264); GG: 1.52% (4/264)) and controls (TT: 81.80% (436/533); GT: 17.82% (95/533); GG: 0.38% (2/533)) (χ(2) = 5.64, P = 0.018). G allele carriers could decrease the risk of colon cancer (adjusted OR = 0.38, 95%CI: 0.23 - 0.63), and the risk of rectal cancer (adjusted OR = 0.65, 95%CI: 0.42 - 0.99). However, for DNMT3B-149C→T , there were no significant deviation in the genotype distributions of polymorphisms between colon cancer (TT: 98.57% (276/280); CT: 1.43% (4/280)) and controls (TT: 97.75% (521/533); CT: 2.25% (12/533)) (χ(2) = 0.82, P = 0.366); and there was no significant deviation between rectal cancer (TT: 99.24% (262/264); CT: 0.76% (2/264)) and controls (TT: 97.75% (521/533); CT: 2.25% (12/533)) either (χ(2) = 1.89, P = 0.169).

CONCLUSIONOur research demonstrates that the-579 G allele is a potential protective factor for the occurrence of CRC, however, the polymorphism of DNMT3B-149 gene shows no close correlation with the occurrence and development of CRC among Chinese population.

The study of human new gene's function has become an increasingly active academic field basically relying on the gene knockout (KO) mouse. The construction of targeting vector economically and efficiently has turned into the key step to acquire a KO mouse because of the low efficiency of recombination with traditional constructed targeting vector. For study of the function of new gene-Resp18, we brought in a new DNA engineering platform-Red/ET recombination to construct Resp18 targeting vector. Red/ET recombineering differs from the conventional ways of vector construction (e.g., PCR, restriction enzyme digestion and ligation) and achieves genetic modification by acquisition, insertion, fusion or replacement of the target gene through small fragments mediated homologous recombination. Now Resp18 targeting vectors of three strategies were yielded successfully through two homologous recombination processes of retrieve and neo-targeting. Red/ET recombination has the advantage of getting longer homology regions without mutation, which makes it a new and reliable alternative to the construction of a targeting vector today.

OBJECTIVETo develop a newly real-time RT-polymerase chain reaction assay for severe acute respiratory syndrome (SARS) related coronavirus in human whole blood.

METHODSA pair of primers and a probe (molecular beacon) had been designed that were specific for the recognition of a highly conservative region between 15 301 and 15 480 of the SARS-related coronavirus polymerase gene sequences obtained from GenBank (G130027616).

RESULTSIn the real-time RT-PCR assay, the extent of SARS related coronavirus amplification was measured in terms of the increase in fluorescence during the amplification process. The 145 bp fragment of PCR product was further confirmed by conventional PCR assay and proved by DNA sequencing to be identical to the target sequence to which the probe was hybridized.

CONCLUSIONThis assay has a broad application for clinical diagnosis and surveillance investigation.
