Objective To explore the characteristics, related risk factors and prognosis of cervical carcinoma in elderly women. Methods 163 cases with stage Ⅰ-Ⅱ cervical carcinoma according to International Federation of Gynecology and Obstetrics (FIGO) criteria underwent radical hysterectomy and pelvic lymph dissection from January 1997 to December 2006. They were divided into aged group, adult group and young group. The clinical pathological data, prognosis and recurrence were retrospectively analyzed. Results The prevalence rate of stage Ⅱ cervical carcinoma was 78.7% (37/47) in aged group, 61.7 % (58/94) in adult group and 59.1% (13/22) in young group. The prevalence difference was statically significant. The prevalence rate of non-squamous cell carcinoma was 8. 5 % (4/47) in aged group, which was higher than that in adult group [5.3%(5/94)]and lower than that in young group [18. 2% (4/22)] (P<0.05). In aged group, pathological grading were 78.7% (37/47) of middle differentiation and 4. 3% (2/47) of low differentiation(P<0. 01). The rate of lymph node metastasis was 8. 51% (4/47)in aged women, 27.7 % (26/94) in adult women and 40.90% (9/22) in young women (P<0. 01). The recurrence rate was similar among the three groups. The death rate was 85.7% in overall recurrent cases, (12/14)in aged group, 73.1% (19/26)in adult group and 50.0% (4/8)in young group, and there was no significant difference (P=0. 193). Conclusions Cervical carcinoma in elderly women has a later clinical stage, higher prevalence of non-squamous cell carcinoma, more middle differentiation tumour tissues and fewer lymphatic metastasis, which can provide evidence for clinical diagnosis and treatment.

Objective To explore relativity between serum cortisol and post-stroke depression in old patients with stroke. Methods Serum cortisols of 41 stroke patients were examined two weeks after stroke, and they were all assessed through Hamilton Depression Scale and then happening rates of post-stroke depression observed in both normal cortisol group and enhanced cortisol group were tested through χ2 test. Meanwhile relativity between serum cortisol level and post-stroke depression were analysised. Results Happening rates of post-stroke depression had an evidently difference between both normal cortisol group and enhanced cortisol group(χ2=4.11;P <0.05). Mark of normal cortisol group was 15.29±7.28, enhanced cortisol group was 25.85±10.81, both groups had an evidently difference( P <0.01). Serum cortisols were not obviously relative to depression degree in normal cortisol group( r =0.295;P =0.194) while they were obviously relative in enhanced cortisol group( r =0.702;P =0.001). Conclusion Enhanced cortisol could forecast higher possibility of depression after the old post-stroke, and detecting cortisol could offer theory foundation for prevention and cure of post-stroke depression.

Objective To investigate the effect and underlying mechanism of Caudatin combined with Gefitinib on Gefitinib resistance induced by HGF in PC-9.Methods Model of EGFR-TKIs resistance in PC-9 cells was induced by exogenous HGF and co-cultured with MRC-5.Caudatin was tested as a drug resistant modulator to reverse the resistance of Gefitinib in PC-9 cells induced by HGF by MTT assay.Western blot was performed to observe the mechanism of Caudatin combined with Gefitinib reversing the resistance of PC-9 induced by HGF.Results The resistance of gefitinib to PC-9 was induced by exogenous HGF and co-cultured with MRC-5 which could reduce relative inhibitory rate ( P<0.05 ) .Neither caudatin ( 0-32 μM ) or Gefitinib (1μM) alone could significantly inhibit proliferation of PC-9 in the presence of HGF, which could be inhibited in a dose-dependent manner by Caudatin combined with Gefitinib ( P<0.05 ); Caudatin combined with Gefitinib down-regulated the phosphorylation levels of Met and PI3K/Akt simultaneously (P<0.05).Conclusion Caudatin could reverse the drug resistance of Gefitinib in PC-9 induced by HGF, the mechanism of which may be related to the inhibition of Met/PI3K/AKT pathway.
