OBJECTIVE:To investigate the improvement effect of Prostatitis capsule on chronic non-bacterial prostatitis(CNP) model rats. METHODS:60 rats were randomly divided into sham operation group (distilled water),model group (distilled wa-ter),Pule'an tablet group(positive control,2 g/kg)and Prostatitis capsule high-dose,medium-dose,low-dose groups(16,8,4 g/kg). Except for sham operation group,other 5 groups were injected Xiaozhiling injection 0.2 mL to reduce CNP model. After 7 d of modeling,they received related medicines,ig,once a day,for 45 d. After 24 h of last administration,prostate lesions were ob-served by eyes and wet quality was weighed. White blood cell(WBC)count and lecithin body(SPL)count were conducted under microscope,and prostate tissue slices were pathologically observed. RESULTS:Compared with sham operation group,prostate showed gray nodules,adhesion in glands and surrounding tissue;wet quality of prostate and WBC,SPL count in prostate tissue were significantly increased(P<0.01);under microscope,there were significant congestion,edema and a variety of inflammatory cell infiltration in prostate interstitial. Compared with model group,gray nodules in prostate in Pule'an tablet group and Prostatitis capsule group were reduced,as well as adhesion degree in prostate and surrounding tissue;wet quality of prostate and WBC,SPL count in prostate tissue were significantly decreased(P<0.01);pathological changes had improved to varying degrees under micro-scope,especially the changes in Prostatitis capsule high-dose group,and prostate tissue only showed mild congestion,edema and little inflammatory cell infiltration. CONCLUSIONS:Prostatitis capsule has a certain improvement effect on CNP model rats.

Objective To investigate the clinical effects of arthroscopic patelloplasty combined with lateral patellar retinaculum release and circumpatellar denervation for treatment of moderate and severe patellofemoral osteoarthritis.Methods A retrospective case-control study was done on 80 patients with moderate to severe patellofemoral osteoarthritis who were treated in our hospital between March 2013 and March 2015.According to treatment methods,the patients were divided into two groups:Group A including 40 cases (22 cases of Outerbridge grade Ⅲ degree and 18 cases of Outerbridge grade Ⅳ) undergone arthroscopic debridement,and Group B including 40 cases (22 cases of Outerbridge grade Ⅲ degree and 18 cases of Outerbridge grade Ⅳ) undergone arthroscopic patelloplasty combined with lateral patellar retinaculum release and circumpatellar denervation.The Kujula scores and Lysholm scores of the patellofemoral joint were compared between the two groups before and after operation.The lateral patellofemoral angle was measured according to patellar axial X-ray performed 3 months after operation to evaluate patellofemoral joint function.Results All patients were followed up for 13-36 months (average 19.8 months).The patellofemoral joint scores of the two groups was increased at different degrees after operation.In moderate patellofemoral osteoarthritis patients,at 3 months after operation and the last follow-up of Group B,Kujula scores [(85.1 ± 6.8)points,(86.8 ± 4.6)points] and Lysholm scores [(88.1 ± 1.8) points,(88.4 ± 2.3) points] were higher than that of Group A [(78.1 ± 5.7) points,(78.3±5.3)points,(82.4 ±2.9)points,and (82.5 ±2.5)points] (P＜0.05).In each group,the Kujula scores and Lysholm scores at 3 months after operation and the last follow-up were improved to be higher than preoperation (P ＜ 0.05),with insignificant statistical difference between the two groups (P ＞ 0.05).According to the Lysholm scores,the excellent rate after operation in Group B (86％) was higher than that of Group A (55％) (P ＜ 0.05).For patients with severe patellofemoral osteoarthritis,Kujula scores [(72.3 ± 5.3) points,(72.7 ± 3.6) points] and Lysholm scores [(75.1 ± 1.9) points,(75.3 ± 2.3) points] at 3 months postoperatively and at the last follow-up in Group B were higher than that of Group A [(70.8 ± 5.2) points,(71.1 ± 4.2) points,(73.4 ± 2.8) points,and (73.6 ± 2.5) points],but the difference was not statistically significant (P ＞ 0.05).Within each group,although the Kujula scores and Lysholm scores at 3 months postoperatively and at the last follow-up were improved compared with before operation,but the difference was not statistically significant (P ＞ 0.05).According to the Lysholm scores,although the excellent rate after operation of Group B (33％) was higher than that of Group A (28％),with insignificant statistical difference (P ＞ 0.05).No matter Outerbridge Ⅲ or Ⅳ patellofemoral osteoarthritis a patient was,the lateral patellofemoral angle of Group A after operation had no significant improvement (P ＞ 0.05),while Group B showed significant improvement after operation (P ＜0.01).Group B had better improvements than that of Group A (P ＜0.01).Conclusions Compared with simple arthroscopic debridement,patelloplasty combined with lateral patellar retinaculum release and circumpatellar denervation can better relieve the symptoms of moderate patellofemoral osteoarthritis and improve knee function.But for patients with severe patellofemoral osteoarthritis,this method is not effective.

OBJECTIVE:To establish the quality standard for Prostatitis capsules. METHODS:TLC method was performed to qualitatively identify Pseudostellaria heterophylla,Acortw tatarinowii,Sargentodoxa cuneata,Rubia cordifolia and Vaccaria segeta-lis in the preparation. HPLC method was adopted to determine the content of leonurine in the preparation. The determination was performed on Agilent Eclipse XDB-C18 column with mobile phase consisted of methanol-0.025 mol/L potassium dihydrogen phos-phate(pH adjusted to 2.5)(24 : 76,V/V)with phosphoric acidat the flow rate of 1.0 mL/min. The detection wavelength was set at 277 nm,and column temperature was 30 ℃. The sample size was 10 μL. RESULTS:The TLC spots of P. heterophylla,A. tatari-nowii,S. cuneate,R. cordifolia,and V. segetalis were clear and well-separated without interference from negative control. The lin-ear range of leonurine were 4.05-81.00 μg/mL(r=0.9999). RSDs of precision,stability and reproducibility tests were all lower than 2.0%. The recovery was 98.47%-103.83%(RSD=2.04%,n=9). CONCLUSIONS:Established standard can be used for quali-ty control of Prostatitis capsules.

Objective To investigate the effect of songling xuemaikang(SL-xmk)pretreatment on the expression of matrix metalloproteinase-9(MMP-9)after focal cerebral ischemia-reperfusion in rats.Methods A total of 45 male Sprague-Dawley rats were randomly allocated into SL-xmk pretreatment,sham operation,and normal saline control group.Preventive gavage was per-formed for 8 weeks in rats using SL-xmk(937.50 mg/kg)suspension in the SLxmk pretreatment group(n = 15);the preventive gavage was performed in rats using the equal volume of normal saline in the sham operation(n = 15)and normal saline control(n = 15)groups.At the end of the pretreatment process,a model of middle cerebral artery occlusion(MCAO)in rats was induced by suture method for 2 hours and reperfusion for 24 hours.The effects of SL-xmk pretreatment on the neurologic deficit scores after transient MCAO,brain water content,and infarct volume in rats were observed.Immunohistochemical staining was used to detect the MMP-9 immunoreactive positive cells in ischemic brain tissue.Results The neurologjc deficit scores(1.21 ± 0.25 vs.2.37 ± 0.35,P = 0.000),the brain water content (76.24% ± 7.09% vs.88.78% ± 6.57%,P = 0.000),the percentage of infarct volume (22.62% ±2.17% vs.27.84% ±3.43%,P =0.000),and the numbers of MMP-9 positive cells(16.20 ± 2.17/mm vs.20.60 ± 2.71/mm,P = 0.000)were all significantly lower than those in the control group.Conclusions SL-xmk pretreatment may significantly inhibit the expression of MMP-9 in the brain tissue of focal cerebral ischemia-reperfusion rats and reduce brain water content and infarct volume.

Irreparable rotator cuff tear can result in pain and should disfunction, and the management of patient with it remains a challenge. A variety of treatment options have been proposed, such as debridement, tuberplasty, partial rotator cuff repair, patch augmented rotator cuff repair, tendon transfers, superior capsule reconstruction, suprascapular nerve ablation or kill, inpace and reverse shoulder arthroplasty. These procedures are still widely debated, The aim of this review is to summarise procedures and the results, the operative essence is to restore the stable rotation center of glenohumeral joint, the choice is dictated by our special need.
