RESUMEN

<p><b>OBJECTIVE</b>To determine the effect of laparoscopic radiofrequency ablation of T1aN0M0 renal cell carcinoma (RCC) with regular follow-up.</p><p><b>METHODS</b>All patients underwent surgery from March 2006 to March 2009. Eight cases were solitary kidney. Twenty-two cases of left RCC and 18 cases of right RCC were diagnozed by ultrasonography and CT scanning.All of the cases were T1aN0M0 stage. No metastasis was found by iconography test. By ultrasound positioning, laparoscopic radiofrequency were performed on the renal tumor. All patients were followed up with eGFR and enhanced-CT.</p><p><b>RESULTS</b>All patients underwent laparoscopic radiofrequency ablation surgery successfully. The mean operation time was (101 ± 19) minutes and the mean blood loss was (90 ± 14) ml (no blood transfusion pre- and post-operation). During postoperative follow-up, enhanced CT revealed complete ablation in 39 cases (the success rate was 97.5%), and 1 residue tumor was confirmed by enhanced CT 7 days post operation. This patient was under close surveillance because of solitary kidney. No progression of the residue tumor was found during the follow-up. One case of recurrence was confirmed by enhanced CT in 6 month after operation. The 3-year recurrence rate was 2.5%. No further intervation was performed on this patient and no change was found in the recurrence area during the follow-up. Both 3-year total survival rate and 3-year cancer specific survival rate were 100%. The mean eGFR was (72 ± 9) ml/(min·1.73 m(2)) in 3 years after surgery. There was no significant difference between pre-and post-operation (P > 0.05).</p><p><b>CONCLUSION</b>Mid-term follow-up results show the effectiveness and safety of laparoscopic radiofrequency ablation in the treatment for T1aN0M0 RCC and have no negative influence on the renal function.</p>

RESUMEN

<p><b>OBJECTIVE</b>To investigate the differential plasma protein profiles in patients with hyperlipidemia & atherosclerosis (H&A) of different patterns of phlegm-stasis syndrome (PSS) for seeking their biomarker proteins.</p><p><b>METHODS</b>Two-dimensional gel electrophoresis and gel screening graphical analysis were performed on plasma proteins got from 146 patients; corresponding protein spots were fetched from the gel for two-stage mass-spectrometric analysis by quadruple time-of-flight mass spectrometry; then the differential proteins for PSS were discriminated by Fisher discriminate analysis.</p><p><b>RESULTS</b>Excepting two uncertain proteins, 7 differential proteins were screened out from the 11 differentially expressed plasma protein spots with variability over 100% in the inter-block matching. Classic analysis found that haptoglobin precursor and fibrinogen gamma chain were possibly the plasma biomarker proteins for H & A; fibrinogen beta chain and apolipoprotein A-I precursor were that set apart PSS from non-PSS; fibrinogen gamma chain, albumin and apolipoprotein A-I precursor were for phlegm syndrome; haptoglobin precursor, adrenomedullin binding protein precursor, albumin and complement component C4 were for stasis syndrome; albumin and adrenomedullin binding protein precursor were for the phlegm-stasis mutual blocking syndrome. Moreover, the above mentioned expressions of possible marker proteins had their own special rule of changing in the transforming progress of PSS.</p><p><b>CONCLUSION</b>This study reported, for the first time, the existence of evident variation of functional protein constitution in different patterns of PSS, and definite compatibility being detected in some functional proteins, which may be the marker proteins for making diagnosis and prognosis of PSS in H&A. Besides, preliminary proof for the transformation of PSS has gained at the functional protein level.</p>

RESUMEN

<p><b>OBJECTIVE</b>To investigate the effects of Apo A1 and B gene polymorphism on avascular necrosis of the femoral head (ANFH) in north Chinese Han population.</p><p><b>METHODS</b>Polymerase chain reaction-restriction fragment length polymorphisms (PCR-RFLP) technique was used in samples of 143 cases with documented ANFH and 92 healthy control matched by age and sex individuals selected from north Chinese Han nationality. The studied loci include promoter region (-75bp) and the intron 1 (+83 bp) of Apo A1 gene, Eco RI,Xba I of Apo B gene; polymerase chain reaction was used to study 3'-VNTR of Apo B gene.</p><p><b>RESULTS</b>At -75 bp in promoter, the frequency of A/A genotype in ANFH group was significantly higher than that in control group (P < 0.01), while the frequency of G/A genotype in ANFH group was significantly lower than that in control group (P < 0.01). No difference was found in the frequency of genotype at +83bp in intron 1 of Apo A1 gene, Eco RI, Xba I and 3'-VNTR loci of Apo B gene.</p><p><b>CONCLUSION</b>Apolipoprotein A1 gene A/A substitution at position -75 in promotor is associated with ANFH, the mutation may be one of the sensitive genes of ANFH, first reported inside and abroad. But no evident relationship was found between gene polymorphism of +75 bp loci of Apo A1 gene, Eco RI loci of Apo B gene, Xba I loci of Apo B gene or 3'-VNTR of Apo B gene and ANFH.</p>
