ABSTRACT
Objective:To investigate the correlation between cyclooxygenase-2(COX-2), estrogen receptor (ER), progesterone receptor(PR) and the formation of endometrial polyps and the increased malignant rate of postmenopausal endometrial polyps.Methods:From January 2018 to January 2019, a total of 160 postmenopausal women treated in the People's Hospital of Changxing County were selected and divided into endometrial polyps group(83 cases) and oothectomy group(42 cases), normal menopause group(35 cases) according to different diseases.The levels of COX-2, ER, PR in the three groups were measured.The expression of COX-2 in mesenchymal cells and glandular epithelial cells, the expression of ER in mesenchymal cells and glandular epithelial cells, the expression of PR in mesenchymal cells and glandular epithelial cells in the three groups were compared, and the correlation between COX-2, ER, PR and increased malignant rate of endometrial polyps was analyzed.Results:The positive expression rates of COX-2 in mesenchymal cells and glandular epithelial cells in the endometrial polyps group(16.9%, 30.1%) were higher than those in the normal menopause group(0.0%, 11.4%) and the oothectomy group(4.8%, 7.1%)(χ 2=4.568, 5.806, all P<0.05 ). There were no statistically significant differences in the expression of ER in mesenchymal cells and glandular epithelial cells among the three groups(χ 2=1.333, 1.412, all P>0.05). The expression of PR in mesenchymal cells and glandular epithelial cells in the endometrial polyps group was lower than that in the normal menopause group and the oothectomy group(χ 2=4.890, 5.022, all P<0.05). COX-2 was positively correlated with the increase in malignant rate of endometrial polyps( r=4.335, P<0.05), PR was negatively correlated with an increase in the malignant rate of endometrial polyps( r=-4.256, P<0.05), and ER had no significant correlation with an increase in the malignant rate of endometrial polyps( r=1.203, P>0.05). Conclusion:COX-2 and PR are significantly related to the formation of endometrial polyps and the increase in malignant rate of postmenopausal endometrial polyps, but there is no significant expression of ER.Therefore, the detection of COX-2 and PR levels is beneficial to provide a certain scientific basis for clinical treatment.
ABSTRACT
OBJECTIVE:To observe therapeutic efficacy and safety of NB-UVB combined with Total glucosides of white paeony(TGP)capsules and Urea cream in the treatment of psoriasis vulgaris. METHODS:A total of 75 patients with psoriasis vulgaris in dermatology department of our hospital during Jan. 2015-Dec. 2016 were divided into control group(37 cases)and observation group(38 cases)according to random number table. Control group was given TGP capsules 0.6 g orally,3 times a day,reducing to 0.3 g,3 times a day if diarrhea or stool increased significantly after taking the medicine+Urea cream,smearing on the skin,day and evening,for consecutive 12 weeks. Observation group was additionally given NB-UVB irradiation with initial dose of 0.36 J/cm2,2 min/time,every other day,adjusted according to skin reaction for consecutive 8 weeks,on the basis of control group. Clinical efficacies of 2 groups were observed,and PASI scores before and after treatment and the occurrence of ADR were observed. RESULTS:One patient of observation group withdrew from therapy after suffering from obvious edematous erythema with pain due to irradiation. All patients of control group completed treatment. Total response rate of observation group (86.49%)was significantly higher than that of control group(56.76%),with statistical significance(P<0.05). Before treatment, there was no statistical significance in PASI scores between 2 groups(P>0.05). After treatment,PASI scores of 2 groups were significantly lower than before treatment,and observation group was significantly lower than control group,with statistical significance(P<0.05). There was no statistical significance in total incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:NB-UVB combined with TGP capsules and Urea cream show good therapeutic efficacy and safety for psoriasis vulgaris,and can significantly decrease PASI score of patients.
