Objective To study the effect and mechanism of Plantago depressa Willd. extract on rats with chronic nonbacterial prostatitis. Methods Sixty rats were divided into six groups randomly: normal control group, model control group, cernilton group, high-, medium- and low- dose Plantago depressa Willd. extract group, ten rats in each group. Chronic nonbacterial prostatitis rat model was established in the animals except of normal control group. Rats in the cernilton group were administrated with cernilton solution( 100 mg . kg-1 ) . High, middle and low dose Plantago depressa Willd. extract groups were given 150, 300 and 600 mg . kg-1 of Plantago depressa Willd. extract, respectively. The rats in the normal control and model control group were treated with the same volume of purified water.The administration was performed once every day, and lasted for three weeks.Effects of Plantago depressa Willd.extract on prostate index (PI), prostate specific antigen (PSA), tumor necrosis factorα ( TNF-α) , interleukin-1β ( IL-1β) , cycloxygenase 2 ( COX-2) , prostaglandin E2( PEG2 ) , transforming growth factor-β1( TGF-β1 ) , and connective tissue growth factor ( CTGF ) levels and pathological changes of prostate tissue in rats were observed. Results PI and PSA levels of the normal control group were(0.8±0.3)mg.g-1 and(106.5±10.6)pg.mL-1, respectively;those of the model control group were(2.2±0.2)mg.g-1 and(319.4±23.4)pg.mL-1 respectively;Those of the cernilton group were(1.6±0.3)mg.g-1 and(179.5±13.7)pg.mL-1 respectively;Those of the low-, medium- and high- dose Plantago depressa Willd.extract groups were(1.8±0.4),(1.3±0.3),(0.8±0.3)mg.g-1 and(263.4±28.6),(178.5±21.5), (143.5±12.9)pg.mL-1, respectively.Compared with the model control group, PI and PSA were significantly decreased(P<0.01) , TNF-α, IL-1β, COX-2, PEG2 , TGF-β1 and CTGF levels in the prostate tissues were decreased ( P<0. 01 ) , and inflammatory cell infiltration and fibrosis of prostate tissue was significantly alleviated in the model control group. Conclusion This study confirms Plantago depressa Willd.extract exerts effective therapeutical effect on chronic nonbacterial prostatitis in rats.

Non-responding pneumonia describes the situation, in which an inadequate clinical response is present de-spite antibiotic treatment. The incidence of treatment failure in community acquired pneumonia (CAP) can range up to 31%. At present, the diagnosis and treatment of this kind of disease remain a great challenge to CAP. For this reason, several stud-ies have attempted to establish risk factors and new strategies for the treatment of non-responding pneumonia. This article re-views the progress of the pathogeny and treatment of non-responding CAP.

BACKGROUND:Although cementation of polyethylene liner into a wel-fixed metal shel during the revision surgery has several advantages compared to total acetabular revision, there are some disputes about its clinical outcomes, especialy regarding the re-revision rate and the prosthetic survivorship. OBJECTIVE:To evaluate the clinical outcomes and safety of cementation of polyethylene liner into a wel-fixed acetabular cup in the revision after total hip arthroplasty with retained stable cup. METHODS:Between March 2012 and November 2014, nine patients underwent revision after total hip arthroplasty with cementation of polyethylene liner into a wel-fixed acetabular cup. There were 1 male and 8 females, aged 43.7 years on average. The time was 9.4 years on average from the primary total hip arthroplasty to revision. Harris Hip Score and prosthesis X-ray films were compared after revision. The effects and safety of cementation of polyethylene liner into a wel-fixed acetabular cup were further evaluated. RESULTS AND CONCLUSION:Nine patients were folowed up for 8-37 months. The Harris hip scores before revision was (49.54±18.28) points previously, and (84.82±10.59) points during final folow-up (t=6.377, P < 0.05). One patient had re-revision surgery because of recurrent dislocation. There were not complications in other patients, resulting in failure rate of 11%. These results indicated that polyethylene liner cementation technique is safe and effective when the wel-positioned and wel-fixed acetabular cup retained.
