ABSTRACT
ABSTRACT:Objective To investigate the clinical features of seronegative rheumatoid arthritis (RA)in western China and its outcomes after one-year treatment with disease modifying anti-rheumatoid drugs (DMARDs) so as to provide evidence for effective therapy.Methods We made a retrospective analysis of 240 RA patients treated in our department from May 2013 to June 2014.We compared the 47 seropositive and 25 seronegative RA patients in clinical features,laboratory parameters and outcomes after one-year DMARDs medication.Results The percentage of seronegative RA was 10.4% (25/240).The number of swollen small joints was significantly smaller in seronegative RA group (P<0 .0 1 ).Compared with those in seropositive RA,the level of hemoglobin was lower,the level of platelets was higher,and the level of alkaline phosphatase was lower in seronegative RA (P<0 .0 5 ).The remission rate was higher in seronegative RA group than in seropositive RA group after one-year DMARDs administration (P<0.05).Conclusion Seronegative RA is not rare in clinic.Even though seronegative RA patients often present fewer swollen small joints, it is difficult to distinguish between seronegative and seropositve RA just based on the clinical features.Besides,hematological damage is more severe in some patients with seronegative RA.Only after one-year treatment with DMARDs,the remission rate is higher in seronegative RA patients than in seropositve RA ones.
ABSTRACT
PURPOSE: We analyzed the clinicopathologic features, including treatment and outcome, and the survival rates between young and elderly patients with gastric cancer. MATERIALS AND METHODS: Clinical information was reviewed for 1086 patients who had undergone a gastrectomy for gastric cancer during a 10-year period from 1990 to 1999, and the patients were assigned to one of two groups: the A group ( or =70 years of age, 85 patients). RESULTS: Compared to the B group, the A group had more females (47.3% vs 32.9%), a greater frequency of family history of cancer (15.4% vs 3.5%), and greater proportions of histologically poorly differentiated tumors (84.5% vs 40.2%) and Lauren diffuse-type tumors (69.1% vs 35.1%)(P<0.05). There was no difference in TNM stage. Cardiopulmonary co-morbidities were more in the B group, respectively, 1.1% (A group) and 11.8% (B group)(P<0.01), but the morbidity and the mortality were similar. Although there was no difference in curability, the B group underwent less aggressive operations in lymph-node dissection above D3 and had a shorter operation time, a smaller number of retrieved lymph nodes, and less adjuvant chemotherapy (P<0.001). However, there were no differences in the disease-specific 5-year survival rates, 67.6% and 67.0% respectively. CONCLUSION: Young and elderly patients with gastric cancer had different clinicopathological features. Especially, elderly patients underwent relatively less aggressive treatment. In spite of these facts, the outcome of treatment and the disease-specific survival rates were not different.

Objective To ameliorate the percutaneous lumbar discectomy(APLD)for improving the effectiveness and amplifying the indicative range of PLD.Methods To ameliorate percutaneous punctured route based on classic PLD and discectomy of extracting pulp out of the herniated disc with special pulpforceps. The statistical analysis of the therapeutic results on 750 disc protrusions of 655 cases undergone APLD following up from 6 to 54 months retrospectively. Results The effective ratios were excellent in 40.2%, good for 46.6% and bad of 13.3%. No occurrance of intervertebral inflammation and paradiscal hematoma, there were only 1 case complicated with injuried cauda equina, and 4 cases with broken appliance within disc.Conclusions APLD is effective and safe, not only indicative for inclusion disc herniation,but also for noninclusion herniation.
