Objective To assess the effects of medicated permeation with traditional Chinese medicine Shujin-Zhitong liquid combined with ion tophoresis on osteoarthritis(OA) of rabbit knee joint in vivo.Methods The modified Hulth OA model was prepared with rabbits by anterior cruciate ligament desmotomy plus medial meniscus resection.Twenty-four model rabbits were randomly divided into three groups: Chinese medicine group: treated with Chinese medicine Shujin-Zhitong liquid by ion tophoresis for 20 minutes per day;positive control group: glucosamine hydrochloride was administered orally per day;blank control group: no treatment was administered to the model rabbits.Serum nitrogen monoxidum(NO) concentration was determined at the time points of prior model making,prior treatment,and 4 and 8 weeks of treatment.At 4 and 8 weeks of treatment,the apoptotic rate of chondrocytes was determined by flow cytometry,and the gene expressions of collagen Ⅱand aggrecan were determined by reverse transcription polymerase chain reaction(RT-PCR).Results The contents of serum NO in Chinese medicine group and positive control group were lower than that in blank control group at 4 weeks after treatment,and the content of serum NO in Chinese medicine group was lower than those in positive control group and blank control group at 8 weeks after treatment.The apoptotic rates in Chinese medicine group and positive control group were lower than that in blank control group at 4 and 8 weeks after treatment.Gene expression levels of collagen Ⅱ and aggrecan in Chinese medicine group and positive control group were higher than that in blank control group at 4 weeks after treatment,while the gene expression level in Chinese medicine group was higher than those in positive and blank control groups at 8 weeks after treatment.Conclusions The treatment of medicated permeation with traditional Chinese medicine Shujin-Zhitong liquid combined with ion tophoresis has shown good therapeutic effect on osteoarthritis(OA) of rabbit knee joint,the mechanism might be the inhibition of chondrocytes apoptosis and reduced secretion of inflammatory factors,and the improvement of cartilage repair by up-regulating related gene expression of chondrocyte.

Objective]To compare the efficacy and safety of retroperitoneal laparoscopic intrasinusal pyelolithotomy (RLIP) and percutaneous nephrolithotomy(PCNL)in the treatment of solitary renal pelvic stone.[Methods]From March 2012 to September 2016,101 patients with solitary renal pelvic stone,divided into RLIP group(n=46)and PCNL group(n=55),were retrospectively analyzed to compare the difference between the two groups in clinical curative effect.[Results]There was no difference between the two groups regarding age,sex,stone side and stone size. Although the operative time was significantly longer,the stone-free rate in the RLIP group was significantly higher than that in the PCNL(P < 0.05). The postoperative complication of urinary tract infection was lower in the RLIP group (P < 0.05),however ,no significant difference was found in postoperative discharge time ,fever (>38.5℃)and the decrease values of hemoglobin and glomerular filtration rate.[Conclusion]Compared to PCNL,RLIP was more efficient and slight safer in the management of solitary renal pelvic stone ,and had a certain value for generalization in clinic.

Objective To evaluate the role of c-AMP-protein kinase A (cAMP-PKA) on the up-regulation of heme oxygenase-1 (HO-1) expression during lipopolysaccharide (LPS)-induced acute lung injury (ALI) in rats.Methods Forty-eight healthy male Sprague-Dawley rats,weighing 180-220 g,aged 2.5-3.0 months,were randomly divided into 4 groups (n =12 each)∶ normal control group (group C),ALI group (group ALI),H89 +ALI group (group H + ALI) and H89 group (group H).In group C,normal saline (solvent for LPS) 0.5 ml was injected via the femoral vein and normal saline (solvent for H89) 0.5 ml was injected subcutaneously 2 h later.In group ALI,10 mg/kg LPS 0.5 ml was injected via the femoral vein and normal saline 0.5 ml was injected subcutaneously 2 h later.In group H +ALI,10 mg/kg LPS 0.5 ml was injected via the femoral vein and 5 mg/kg H89 0.5ml was injected subcutaneously 2 h later.In group H,normal saline 0.5 ml was injected via the femoral vein and 5 mg/kg H89 0.5 ml was injected subcutaneously 2 h later.The rats were then sacrificed at 6 h after iv injection of LPS and the lungs were removed for microscopic examination and lung water content.The pathological changes of the lung were scored.The expression of HO-1 and PKA (by Western blot) and HO-1 mRNA (by RT-PCR) was detected.Results Compared with group C,the pathological score and lung water content were significantly increased,and the expression of HO-1,PKA and HO-1 mRNA was up-regulated in groups ALI and H +ALI (P ＜0.05),and no significant change was found in the parameters mentioned above in group H (P ＞ 0.05).The pathological score and lung water content were significantly higher,and the expression of HO-1,AP-1 and HO-1 mRNA was significantly lower in group H + ALI than in group ALI (P ＜ 0.05).Conclusion Activation of signaling pathway c-AMP-PKA is involved in the up-regulation of HO-1 expression during LPS-induced ALI in rats.

Objective To evaluate the role of activator protein-1 (AP-1) in the up-regulation of heme oxygenase-1 (HO-1) expression during lipopolysaccharide (LPS)-induced acute lung injury (ALI) in rats.Methods Forty-eight healthy male Sprague-Dawley rats,weighing 200-220 g,aged 2.5-3.0 months,were randomly divided into 4 groups (n=12 each): normal control group (group C),ALI group,curcumin + ALI group (group Cur+ ALI),and curcumin group (group Cur).In groups C and ALI,normal saline 0.5 ml and LPS 10 mg/kg (0.5 ml) were injected intravenously,respectively,30 min after 0.1％ dimethyl sulfoxide (the vehicle for curcumin) 0.5 ml was injected intraperitoneally.In groups Cur+ ALl and Cur,curcumin 20 mg/kg (0.5 ml) was injected intraperitoneally,and 30 min later LPS 10 mg/kg and normal saline 0.5 ml were injected,respectively.The rats were then sacrificed at 6 h after injection of LPS.The lungs were removed for microscopic examination.The pathological changes of the lung were scored.The malondialdehyde (MDA) content,superoxide dismutase (SOD)activity and expression of HO-1,AP-1 and HO-1 mRNA in lung tissues were determined.Results Compared with group C,the pathological score and MDA content were significantly increased,the SOD activity was significantly decreased,and the expression of HO-1,AP-1 and HO-1 mRNA was up-regulated in groups ALl and Cur +AL(l) (P ＜ 0.05),and no significant change was found in the parameters mentioned above in group Cur (P ＞ 0.05).The pathological score and MDA content were significantly higher,and the SOD activity and expression of HO-1,AP-1 and HO-1 mRNA were significantly lower in group Cur + ALl than in group ALI(P ＜ 0.05).Conclusion Transcription factor AP-1 activation is involved in the up-regulation of HO-1 expression during LPS-induced ALI in rats.

Objective To evaluate the effect of electro-acupuncture (EA) at Zusanli and Feishu on endotoxin shock-induced acute lung injury in rabbits.Methods Sixty healthy male New Zealand white rabbits aged 2 months weighing 1.5-2.0 kg were randomly divided into 6 groups (n =10 each):group sham operation (group S); group zinc protoporphyrin-Ⅸ (ZnPP-Ⅸ) (group Z); group lipopolysaccharide (LPS) (group L); group LPS + EA (group EL) ; group LPS + sham EA (group SEL) and group LPS + EA + ZnPP-Ⅸ (group ELZ).The animals were anesthetized with intraperitoneal 10％ chloral hydrate 400 mg/kg and tracheostomized.The animals kept spontaneous breathing.Right internal carotid artery was cannulated for BP monitoring.Ear vein was cannulated for drug administration.LPS 5 mg/kg was injected iv in groups L,EL,SEL,ELZ.Endotoxin shock was confirmed by decrease in BP by 20 ％ of the baseline value and PaO2/FiO2 ≤ 300.ZnPP-Ⅸ (heme oxygenase (HO-1 ) inhibitor)10μmol/kg was injected intraperitoneal at 2 h after LPS injection in groups Z and ELZ.Bilateral 15 min EA stimulation of Zusanli and Feishu ( according to atlas of animal acu-points) was performed once a day for 5 days before LPS administration in groups EL and ELZ.The animals were sacrificed by blood-letting at 6 h after LPS administration.The lungs were removed for microscopic examination (0 =no injury,4 =most severe injury),detection of alveolar epithelial cell apoptosis (by TUNEL) and determination of HO-1 protein and mRNA expression.Results LPS significantly increased lung injury scores,alveolar epithelial cell apoptosis index (the number of apoptotic cells/total cells) and HO-1 protein and mRNA expression.EA significantly attenuated lung injury and alveolar epithelial cell apoptosis induced by LPS and further increased the expression of HO-1 protein and mRNA in group EL as compared with group L.The protective effects of EA was counteracted by ZnPP- Ⅸ in group ELZ.Conclusion EA at Zusanli and Feishu can attenuate endotoxin shock-induced lung injury by up-regulation of HO-1 expression and inhibiting alveolar epithelial cell apoptosis in the lung.

Objective To explore the protective effect of astragalus injection(黄芪注射液)on cerebral cells after craniocerebral injury.Methods Sixty male Sprague-Dawley(SD)rats were randomly divided into five groups(each n=12).In the control group,only anesthesia and cranial bone surgery was performed, which did not impact on dura mater.In the model group,a freefall method was used to cause the left parietal lobe of brain limited contusion and saline was given.In the low,medium and high-dose astragalus injection (5,10,20 ml/kg)treatment groups,astragalus injection was injected intraperitoneally after injury at 30 minutes and 12 hours after injury respectively.After 24 hours of injury in each group,the rats were executed.The brain tissue from contusion was taken out and content changes of Ca~(2+),Mg~(2+),glutamate (Glu)and plasma endothelin(ET)were measured.Results In the model group,the Ca~(2+),Glu and ET contents in the rat brain tissues were significantly higher,but Mg~(2+)content was markedly lower than that of the control group(all P0.05).Conclusion Astragalus has a protective effect on nerve cells after craniocerebral injury.

Objective To evaluate the role of mitochondrial fusion?fission in endotoxin?induced a?cute lung injury in rats. Methods Twenty healthy male Sprague?Dawley rats, weighing 160-180 g, were e?qually and randomly divided into either control group ( group C ) or endotoxin?induced acute lung injury group (group L) using a random number table. Lipopolysaccharide 5 mg∕kg was injected intravenously in group L, while the equal volume of normal saline 0?5 ml was given instead in group C. The animals were sacrificed at 6 h after administration of lipopolysaccharide or normal saline. The lungs were immediately re?moved for measurement of wet to dry lung weight ratio ( W∕D ratio) , superoxide dismutase ( SOD) activity and malondialdehyde ( MDA) content. The mitochondrial fusion proteins mitofusin 1 ( Mfn1) , Mfn2 and op?tic atrophy 1 ( OPA1) mRNA and protein expression was detected, and mitochondrial fission proteins dy?namin?related protein 1 (Drp1) and fission 1 (Fis1) mRNA and protein expression was also detected in lung tissues. Results Compared to group C, the W∕D ratio and MDA contents in lung tissues were signifi?cantly increased, SOD activity was decreased, Mfn1, Mfn2 and OPA1 mRNA and protein expression in lung tissues was down?regulated, and Drp1 and Fis1 mRNA and protein expression was up?regulated in group L. The pathological damage to lung tissues was obviously aggravated in group L when compared to group C. Conclusion The mechanism underlying endotoxin?induced acute lung injury is related to enhanced oxidative stress responses caused by decreased mitochondrial fusion and increased mitochondrial fission in rats.
