Objective To investigate the therapeutic mechanism of bazedoxifene, the third-generation selective ER modulator (SERM), on endometriosis lesions in a rat model. Methods Endometriosis was induced by transplanting pieces of endometrium from other syngeneic rats that were as donors onto the subcutaneous of other unmated female rats. The rats with successful ectopic implants were divided into two groups:control group (n=10) and bazedoxifene group (n=10). The macroscopic morphology, volume, histopathology of ectopic implant and rats uterine wet weight were determined before and after the treatment. Expression of proliferation cell nuclear antigen (PCNA), ER and PR in the eutopic endometrium and endometriosis lesions detected by immunohistochemistry in the two groups. Results (1) The gross morphology and histological changes of endometriosis lesions in rats after treatment: compared with the control group, it was obviously depauperated and had more less glands and blood vessels in the stroma. (2) The change of rats′weight, the volume of endometriosis lesion before and after treatment and rats uterine wet weigh after treatment respectively in the control group and the bazedoxifene group:rats′ weight were respectively before treatment: (201±17) g, (202±18) g, that were respectively after treatment: (266±16) g, (261±16) g, which showed no significant difference between two groups before and after treatment (P>0.05). The volume of ectopic implant before treatment were respectively (85±17) mm3, (85±12) mm3, and showed no significant difference between two groups;that were respectively (48±11) mm3, (24±9) mm3 afte rtreatment, which was significantly decreased compared with the control group (P<0.05). Rats uterine wet weight after treatment were respectively:(0.77±0.16) g, (0.45±0.18) g, and was significantly reduced compared with the control group (P<0.05). (3) The protein expression levels of PCNA, ER and PR in the endometriosis lesions after treatment were respectively 0.282 ± 0.044, 0.51 ± 0.06, 0.49 ± 0.05 in the control group, 0.191 ± 0.020, 0.23 ± 0.03, 0.48 ± 0.06 in the bazedoxifene group; that in eutopic endometrium were respectively 0.369 ± 0.081, 0.56 ± 0.08, 0.56 ± 0.10 in the control group, 0.211 ± 0.037, 0.27 ± 0.05, 0.54 ± 0.08 in the bazedoxifene group;the protein expression levels of PCNA and ER in endometriosis lesions and the eutopic endometrium were significantly decreased in the bazedoxifene group compared with the control group (P<0.05), but the protein levels of PR in endometriosis lesionsand and the eutopic endometrium were not significantly altered by treatment (P>0.05). Conclusion Bazedoxifene could obviously reduce the size of endometriosis lesions, the mechanism may be related with suppressing estrogen-induced proliferation, the expression of ER and direct ER antagonism by this SERM.

Objective To study the clinical characteristics of healthcare-associated pneumonia (HCAP).Methods A retrospective cohort study was conducted on consecutive hospitalized pneumonia cases from January 2007 through April 2008.Results HCAP group of 75 patients was compared with 133 patients of community-acquired pneumonia (CAP) and 76 patients of hospital-acquired pneumonia (HAP). Most of HCAP patients had a history of recent hospitalization (47 cases), clinical IV infusion (27 cases), and prior chemotherapy or antibiotic therapy (27 cases). Underlying diseases were identified in 71 (94.7%) of HCAP patients, significantly higher than that in CAP group (37.6%, P<0.01). Positive sputum culture in CAP, HCAP and HAP was 22.6%, 56.9%, 77.6% respectively. Antibiotic resistance of bacteria in HCAP (71.43%) and HAP (80%) was comparable (P>0.05). Initial antibiotic therapy was effective in 47 (62.6%) cases of HCAP. Only 52.9% of the identified pathogens were sensitive to initial antibiotic therapies. The mortality of HCAP (12%) was similar to HAP (23%, P>0.05), but significantly higher than CAP (3%, P<0.05).Conclusions HCAP is a common type of pneumonia, which is characterized by more resistant pathogens, higher mortality, more comorbidities and poor outcomes. Antibiotic therapy should cover the hospital acquired bacterial pathogens.
