Lymph node mapping in rabbit liver cancer with nanocarbon and methylene blue injecta

OBJECTIVE

To discuss the value of lymph node mapping in rabbit liver cancer with nanocarbon and methylene blue injecta.

METHODS

Rabbit liver cancer model was established by transplanting VX2 cells with laparotomy in celiac planting method. Twenty Japan white rabbits were divided into two groups randomly. Each group had 10 rabbits. Lymph node mapping in two groups rabbit liver cancer were observed. Two groups rabbit liver cancer and local lymph nodes were removed. The number and location of local lymph nodes were recorded, and then the samples were obtained from both groups.

RESULTS

The lymph nodes dyed time was (100.50±29.92) s in nanocarbon group, and (11.20±4.18) s in methylene blue group with statistical significance between two groups (P=0.000). In the comparison of lymph node fading time, nanocarbon group was (2.22±0.74) h, methylene blue group was (1.63±0.54) h, nanocarbon group was longer than the methylene blue group, but without statistical significance (P=0.058). The accuracy was 87.5% (35/40) in methylene blue group, while, the nanocarbon group was 87.2% (34/39), with statistical significance (P=1.000).

CONCLUSIONS

Experimental results show that application of nanocarbon injection and methylene blue injection during resection of liver cancer and local lymph nodes in rabbit liver cancer model has obvious tracer function in liver cancer and lymphatic drainage. It can reduce the complexity and risk of the operation, and avoid the blindness in the process of traditional lymph node dissection surgery. Besides, they can effectively reduce the number of residual lymph nodes after operation. It can achieve the lymph node dissection more thoroughly, promptly, easily and safely.

Correlation between single nucleotide polymorphism of rs3811047 in IL-1 F7 gene and rheumatoid arthritis susceptibility among Han population in central plains of China

OBJECTIVE

To discuss the association between single nucleotide polymorphism (SNP) of rs3811047 in IL-1 F7 gene and rheumatoid arthritis (RA) susceptibility among the Han population in central plains of China.

METHODS

A total of 276 RA patients admitted to our hospital from December 2009 to December 2011 together with 276 healthy physical examinees in the same period were chosen as the subjects. The typing for rs3811047 SNP in IL-1 F7 gene was carried out by using ligase detection reaction and polymerase chain reaction technique. And the frequency of each allele and genotypes distribution was calculated so as to evaluate the association between genotype distribution and RA susceptibility.

RESULTS

The frequency of A allele of rs3811047 in IL-1 F7 gene in RA group and control group was 16.27% and 17.68%, respectively, and that of G allele in two groups was 83.73% and 82.32%, respectively. The difference between two groups wasn't statistical significant (P >0.05). The frequency of genotype AA, AG and GG in RA group was 2.19%, 27.84% and 69.97%, respectively, while that in control group was 2.94%, 29.78% and 67.28%, respectively. The difference of distribution of three genotypes was not statistically significant (P >0.05). RA patients with A allele were better than those without A allele in joint swelling index, rest pain, HAQ scoring and blood sedimentation. There was significant difference between two groups in above indexes (P<0.05/P<0.01).

CONCLUSIONS

No significant correlation between RA susceptibility among the Han population in central plains of China and rs3811047 SNP inIL-1 F7 gene is observed. However, A allele of rs3811047 has certain influence on the condition of RA patients.

Efficiency of HAART in the prevention of mother to children HIV-1 transmission at Saint Camille medical centre in Burkina Faso, West Africa

OBJECTIVE

To evaluate efficiency of HAART in the prevention of mother to child HIV transmission.

METHODS

A longitudinal study was conducted on 1 300 women attending the antenatal service at Saint Camille Medical Centre from September 2010 to July 2011. The HIV status of mothers was determined by rapid tests and ELISA. Discordant results were confirmed by real-time PCR. PCR was used to determine HIV status of children born from HIV-positive mothers.

RESULTS

Among 1 300 pregnant women tested for HIV, 378 were seropositive. Mothers were predominantly housewives (69.7%), and their mean age was (28.32±0.15) years. The overall prevalence of HIV transmission from mother to child was 4.8% (18/378). This prevalence differed significantly from 0.0% (0/114) to 6.8% (18/264) in children born from mothers under HAART and those with mothers under New Prophylactic Protocol (AZT + 3TC + NVP), respectively (P< 0.01). Children's mortality rate during the medical follow up was 1.3% (5/378). Among 16 women with HIV dubious status by ELISA, the Real Time PCR confirmed 2/16 (12.5%) as HIV positive.

CONCLUSIONS

The protocol of prevention of mother to children HIV transmission (PMTCT) is effective. The rate of HIV vertical transmission is significantly reduced. Early diagnosis determined by PCR of children born from HIV-positive mother is necessary and recommended in the context of PMTCT in Burkina Faso. We also found that PCR is an effective tool to confirm HIV status in pregnant women.
