Objective To evaluate the therapeutic effects of three-dimensional conformal radiation therapy (3DCRT) in combination with transcatheter arterial chemoembolization (TACE) for stage Ⅱ primary liver cancer. Methods Eighty-one patients were retrospectively analyzed, including 36 received 3DCRT combined with TACE (Group A) and 45 received TACE alone (Group B). The short-term therapeutic effects and 1-, 2-, 3-year survival rates, average survival time of the dead patients, and side effects were compared between the two groups. Results The follow-up rate was 100%. The numbers of patients finished 1-, 2- and 3-year follow-up were 55,19 and 6,respectively. The reponse rates were 72% in group A, and 60% in group B, which were not significant different (χ~2= 1.32, P > 0.05). The 1-, 2- and 3-year survival rates of the dead patients were 83%, 63% and 25% in group A and 75%, 37% and 8% in group B. The corresponding average survival time was 21 months and 16 months, respectively. The differences of 2- and 3-year survival rates were significant between group A and B. (χ~2= 4.87, P < 0. 05 ). The incidence and se-verity of side effects did not differ significantly between the two groups. Conclusions In patients with stage Ⅱ primary liver cancer, 3DCRT combined with TACE, being more effective than TACE alone, can prolong the long-term survival without increasing the toxicities.

Objective To investigate the correlation of XRCC1 Arg194Trp Arg399Gln Single nucleotide polymor-phism (SNP) with radiotherapy response of squamous cell carcinoma of cervix. Methods Patients with exogenous type cer-vical squamous cell carcinoma confirmed by histopathology were selected for our study. These include:patients in stageⅠ(4 cases), patients in stageⅡ(36 cases), patients in stageⅢ(30 cases), patients in stageⅣ (3 cases). There are 30 patients with tumor diameter less than 4 cm and 43 patients with tumor diameter over 4 cm in our test. There are 36 cases with dose point A less than 80 Gy and 37 cases with dose point A over 80 Gy . Radiotherapy outcomes showed 47 cases of complete re-mission and 26 cases of part remission. Polymorphisms Arg194Trp, Arg399Gln of XRCC1 gene in 73 cervical cancer pa-tients were analyzed by mismatch amplification polymerase chain reaction (MAMA-PCR). Results Arg/Arg, Arg/Trp, TrP/Trp of Arg194Trp genotype distribution were 31 (42.5%), 37 (50.7%), 5 (6.8%) respectively. Arg/Arg, Arg/Gln, Gln/Gln of Arg399Gln distribution were 6 (35.6%), 39 (53.4%), 8 (11.0%) respectively. The response to radiotherapy was not statistical-ly significant in three genotypes, Arg/Arg, Arg/Trp, TrP/Trp of XRCC1 at codon 194(P>0.05). Neither was XRCC1 at codon 399. Multivariate analysis showed that late clinical stage was a risk factor of part remission. Conclusion SNP of XRCC1 gene at codon 194 and codon 399 could not predict clinical response of patients with squamous cell carcinoma of cervix to ra-diotherapy. The patients with advanced cervical cancer had poor response to radiotherapy.

Objective To prepare Paracetamol (APP) multiloculated implant loaded with poly-lactide-co-glycolide acid (PLGA) and to study the drug release profile in vitro. Methods APP multiloculated implant was fabricated by micro-electro-mechanical system (MEMS), and high-performance liquid chromato graphy (HPLC) measurement was used to investigate in vitro drug release profile. HPLC analysis was carried out by employing C18 column and a mixture of methanol-water (15∶85) as mobile phase. The detection wavelength was 215nm and flow rate was 0.8mL/min. Results With different multiloculated shape, the rate of the drug release in vitro was varied significantly. Moreover, the releasing of APP multiloculated implant with ecto-tetragonum ento-hexagon in vitro conformed to Higuchi equation. Conclusion The technology of the preparations is feasible, and the structural and morphological characteristics of the multiloculated implant have a significant impact on the release speed of the drug delivery system.
