Objective To observe the effects of intra-articular injection of sinomenine on the expressions of vascular endothelial growth factor (VEGF) and nerve growth factor (NGF) in articular cartilage and synovium of rabbit knee osteoarthritis models; To discuss its mechanism of action. Methods Totally 40 New Zealand white rabbits were randomly divided into 4 groups: control group, model group, hyaluronate group and sinomenine group. Model group, hyaluronate group and sinomenine group established knee osteoarthritis model by using intra-articular injection of papain enzyme and were treated with saline, sodium hyaluronate and sinomenine respectively for 30 d, except for the control group. After treatment, method of immunohistochemistry was used to detect the expressions of VEGF and NGF in rabbit articular cartilage and synovium. Results Compared with the control group, the expressions of VEGF and NGF in articular cartilage and synovium of model group significantly increased (P<0.01); compared with the model group, the expressions of VEGF and NGF in articular cartilage and synovium of sinomenine group significantly decreased (P<0.05, P<0.01); the expressions of VEGF and NGF in articular cartilage and synovium in sinomenine group were lower than hyaluronate group (P<0.05, P<0.01). Conclusion Intra-articular injection of sinomenine can down-regulate the expressions of VEGF and NGF in articular cartilage and synovium of rabbit knee osteoarthritis.

Objective To investigate infection status and antimicrobial resistance mechanism of methicillin-resistant Staphylococcusaureus(MRSA),and provide reference for the rational antimicrobial use in clinic. Methods Staphylococcusaureus (SA)isolated from various specimens in Xuzhou area in 2012-2015 were collected,MR-SA strains were preliminarily screened by cefoxitin disk diffusion method,and confirmed by amplification of mecA gene,antimicrobial resistance of MRSA was determined by Kirby-Bauer method,minimal inhibitory concentration (MIC)was measured by E-test method,genotypes of staphylococcal chromosomal cassette mec(SCCmec)were de-termined by multiplex PCR. Results A total of 116 strains of MRSA were identified among 210 SA strains in 2012-2015,114 of which were positive for mecA gene,the total detection rate of MRSA was 55.24% . Susceptibility rates of MRSA to vancomycin,quinupristin/dalfopristin,and linezolid were all 100% ,resistance rates of MRSA to chloramphenicol and furantoin were both low,which were 15.52% and 1.72% respectively,resistance rates of MR-SA to 10 kinds of antimicrobial agents were all>80% ;resistance rates of MRSA to penicillins,aminoglycosides, macrolides,quinolones,sulfanilamide,rifampicin,tetracycline,and clindamycin were all higher than methicillin-sensitive Staphylococcusaureus(MSSA). MICs of vancomycin to MRSA in 2012-2015 were all 1.0μg/mL,MIC90 were all 1.5μg/mL,one MRSA isolate was with a vancomycin MIC of 2.0μg/mL in 2015. MRSA typing results of 116 MRSA isolates showed that SCCmec II,SCCmec III,and SCCmec IV accounted for 9.48% (n= 11),73.28% (n= 85),and 1.72% (Iva,n= 2;IVb,n= 2)respectively,13.79% (n= 16)of MRSA isolates were nontypeable, SCCmec I and SCCmec V type strains were not found. Conclusion MRSA is seriously multidrug-resistant,the drift has not been discovered in MIC value of vancomycin against MRSA,the major SCCmec genotype of MRSA is SCCmec III,infection control measures should be taken to control MRSA infection.

OBJECTIVE To investigate the effect of sodium ferulate (SF) on lipopolysaccharide (LPS)-induced preterm delivery and intra-uterine fetal death (IUFD). METHODS Pregnant Kunming mice were subcutaneously pretreated with SF (25 or 50 mg · kg-1) from gestational day (GD) 10 to GD 15 and with the single injection of LPS (150μg·kg-1, ip) on GD15.5. The incidence of preterm delivery and IUFD was observed. HE staining was used for uterine and placental histological evaluation. The levels of thiobarbituric acid reactive substances (TBARS) and reduced glutathione (GSH) as well as the activities of glutathione S-transferase (GST) and glutathione peroxidase (GSH-Px) were detected in the maternal liver, placenta, and fetal liver using commercial kits. Interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) levels in amniotic fluid were evaluated by enzyme linked immunosorbent assay. RESULTS For LPS group, the incidence of preterm was 47.8%, delivery time was (17.5 ± 1.3) d, and the pups′survival rate was only 42.6%. Compared with LPS-treated group, SF 50 mg · kg-1 group showed a lower incidence of preterm (14.3%, P<0.01), longer gestational days (18.4 ± 0.5, P<0.05), and a higher pups′survival rate (75.6%, P<0.01). SF 50 mg · kg-1 restored the LPS-induced GSH both in the maternal and fatal liver (a tendency without statistical significance), GST activity〔(163±82) kU·g-1 protein vs (95±90) kU·g-1 protein, P<0.01)〕in the placenta, TBARS content〔(2.5±0.4)μmol·g-1 protein vs (3.1±0.6)μmol·g-1 protein, P<0.01〕in the fetal liver, and TNF-αlevel〔(11±8) ng·L-1 vs (20±8) ng·L-1, P<0.01〕in the amniotic fluid. SF also attenuated LPS-induced placental congestion and neutrophil infiltra?tion in the uterus. CONCLUSION SF may protect against LPS-induced preterm delivery and IUFD, and anti-oxidation as well as anti-inflammation may contribute to these effects.

OBJECTIVETo investigate the influence of seasons, blood types and semen parameters on the cryosurvival rate of frozen-thawed spermatozoa from sperm donors.
METHODSWe retrospectively analyzed the influence of seasons, blood types, abstinence period, semen volume, sperm morphology, and pre-freeze sperm motility and concentration on the cryosurvival rate of frozen-thawed sperm in 4 088 semen samples from Shaanxi Human Sperm Bank.
RESULTSThe cryosurvival rate of the post-thaw sperm was correlated negatively with the progressive motility of the pre-freeze sperm (r = -0.262, P < 0.01), but positively with pre-freeze sperm concentration (r = 0.247, P < 0.01), and it was significantly higher in the 6-day abstinence group ([70.2 +/- 5.4]%) than in the other abstinence groups (P < 0.01), so was it in the normal sperm morphology rate > 20% group ([71.4 +/- 5.1]%) than in the others (P < 0.01). The survival rate of the post-thaw sperm was not correlated with seasons, blood types, and semen volume (P > 0.05).
CONCLUSIONSperm motility, concentration and morphology and the abstinence period of sperm donors may be valuable predictors of the cryosurvival rate of post-thaw sperm, but no correlation was found between the survival rate and seasons, blood types and semen volume.

OBJECTIVETo discuss long-term clinical results of using Zweymüller cup to treat protrusio acetabuli.
METHODSFrom May 1998 to September 2006, 31 patients with 39 hips diagnosed protrusio acetabuli were treated with Zweymüller cup in total hip arthroplasties or revisions. There were 12 men and 19 women with average age of 57.6 years (from 30 to 82 years). The reasons causing protrusio acetabuli were as followed: rheumatoid arthritis 3 cases 6 hips, osteoarthritis followed femoral head necrosis 7 cases 12 hips, acetabular wear after hemi-arthroplasty 11 cases 11 hips and acetabular component loosening 10 cases 10 hips. During all operations, Zweymüller cup was used to fix the acetabular part.
RESULTSAll cases were followed up 6 months and one year after operations. Two patients with 3 hips were died for lung cancer and acute myocardial infarction respectively. Twenty-four cases with 31 hips got recent follow-up with average 7.4 years (from 5.0 to 11.5 years). The average Harris score improved from 31.0 (from 14 to 61) preoperatively to 84.7 (from 70 to 95) postoperatively. There was one infection in right hip after bilateral hip arthroplasty treating by removal prosthesis and cement spacer insert. But until now this patient still did not get revision for her internal medicine. One rheumatoid arthritis patient with two-stage bilateral hip arthroplasty was found slight internal migration and loosening line of left acetabular component, but the patient had no pain with good hip function. All other cases had good hip functions and were very satisfied with clinical results.
CONCLUSIONUsing Zweymüller cup to treat protrusion acetabuli can get strong fixations and perfect medium and long-term clinical results for over 7.4 years.

OBJECTIVETo discuss the treatment and clinical result of using titanium cerclage band to teat intra- and post-operative femoral fracture in total hip arthroplasty.
METHODSFrom August 1999 to September 2007, twenty-two patients who suffered from intra-and post-operative femoral oblique fracture in total hip arthroplasty were reviewed among 2186 consecutive total hip arthroplasty patients performed by one surgeon. There were 12 fractures occurred intraoperative and 10 fractures postoperative. There are 9 primary and 13 revision total hip arthroplasty patients including 10 men and 12 women. All fractures are classified as Vancouver B1 type in 15 cases and B2 type in 7 cases. Two to five titanium cerclage bands had been used to fix the fracture followed by open reduction with 13 cases using 2 cerclage bands and 7 cases using 3 bands and 1 case using 4 bands and 1 case using 5 bands. Whether change the original stem or not depended on the classification of fractures and stability of stems. There were 15 cases of type B1 and 1 case of type B2 without changing stems and 6 cases of type B2 changing to revision stems of the same series of original stems.
RESULTSAll fractures showed successfully union for 12 - 20 weeks (average 18 weeks) after operation. The average Harris score of the hip improved to 90 points (80 to 95 points) at an average 6.5 years follow-up (4 to 11 years) and the average range of motion of the hip got to 120° (105° - 135°). Femoral prostheses were well-fixed without any subsidence or lucent lines or loosening. All patients were satisfied with the results with well-fixed and good alignment of femoral stem.
CONCLUSIONSStrong fixation of the fractures and good initial stability of femoral stem can be obtained using titanium cerclage bands to fix the intra- and post-operative femoral oblique fracture. Original stems should be changed to revision stems in case of type B2 and be retained in case of type B1.
