A highly sensitive fluorescence spectroscopic method was established for the selective determination of estradiol, which took advantages of the excellent molecular recognition capability of aptamer and the energy transfer between the specific fluorescent groups. The effects of the pH value, buffer constituent and concentration, the concentration of DNA, the experimental temperature and response time on the detection of estradiol were studied. Under the optimal conditions (50 mmol/L BR buffer solution with pH value at 7. 4, 1. 0×10-7 mol/L for each DNA strand, incubation at 45 ℃, response time 19 min), the change of the fluorescence intensity (ΔI) versus the logarithm of the concentration of estradiol ( lgC) was linear over a concentration range from 1. 0×10-11 mol/L to 5. 0×10-9 mol/L with good linear correlation (r=0. 9953). The limit of detection (LOD) was found to be 6. 0×10-12 mol/L (S/N=3). This method was successfully applied to the detection of estradiol in human urine, with the recovery in the range of 94. 0%-103. 5%. This method showed good precision and accuracy.

Objective To investigate the relationship between subclinical cervical HPV infection and recurrence of condyloma acuminatum (CA) in patients. Methods Cervical swabs were collected from 52 patients with frequently recurrent CA, 55 patients with infrequently recurrent CA, and 65 normal human controls. The Cenechip method was performed to detect the presence and type of HPV in cervical swabs followed by a statistical analysis. Results HPV was found in 67.3% (35/52) of swabs from patients with frequently recurrent CA, 5% (19/55) from patients with infrequently recurrent CA, and 4.6% (3/65) in the controls. There was a statistical difference among the three groups in the detection rate of HPV. Conclusion The subclinical cervical HPV infection may contribute to the recurrence of CA.

ObjectiveTo explore the characteristics of traditional Chinese medicine (TCM) syndrome differentiation in chronic complications of type 2 diabetes mellitus (DM).Methods124 patients with chronic complications of type 2 DM were scored by 5 grades according as the severities of their symptoms. There were 5 kinds of patterns such as deficiency of Qi, deficiency of Yin, deficiency of Yang, blood stasis and retention of phlegm and fluid by which the TCM syndrome differentiation was generalized.ResultsThe sequence of TCM patterns was deficiency of Yin, blood stasis, deficiency of Qi, deficiency of Yang and retention of phlegm and fluid, and the syndrome of the two formers were greater than 50%. The proportion of unity of deficient and excessive pattern was 80.5%. Three larger syndrome types were deficiency of both Yin and Yang combined with blood stasis (17.7%), Qi-Yin deficiency with blood stasis ( 16.9 %) and Yin deficiency with blood stasis (16.9%). There was a statistically significant difference in TCM syndromes which were divided into different groups by course of diseases (P<0.05). At onset of DM, the typical symptoms were less observed in the group whose course of disease was less than 5 years, and only 39.1% of patients had the typical symptoms. But at the same time, the prevalences of hypertension and hyperlipidemia were higher in this group than in the others, respectively 63.0% and 87.0%.ConclusionThe primary syndrome is unity of deficient and excessive pattern in chronic complications of type 2 DM and deficiency of Qi and blood stasis are the commonest patterns in course of DM.

AlM:To compare the clinical results of different surgical methods for diabetic antipathy.
METHODS: Eighty cases ( 102 eyes ) with diabetic antipathy were selected in our hospital from January 2012 to December 2013. Thirty-eight cases (48 eyes) in group A received joint surgical treatment, 42 cases (54 eyes) in group B took staging of surgical treatment. The clinical effect was observed in both groups.
RESULTS: The vision after surgery was improved than that of before surgery in two groups, there were no significant differences ( P > 0. 05 ). A postoperative complication rate was 16. 7% in group A and 22. 2% in group B, showed no significant difference (P>0. 05).
CONCLUSlON: Surgery and staging joint surgery are both feasible for diabetic retinopathy patients, can, improve the visionr. Both of them are worthy of clinical application.
