OBJECTIVETo introduce a new measuring tool for measuring postoperative limb length exactly, and to provide a convenient and effective method to control limb length after total hip replacement.

METHODSFrom January 2013 to September 2014, 102 patients undergoing primary unilateral hip replacement were divided into two groups: experimental group and control group. There were 51 patients in the experimental group, including 25 males and 26 females, ranging in age from 37 to 92 years old, with an average of 60.41 years old. The patients in experimental group were treated with new method to control limb length. Other 51 patients in the control group, including 27 males and 24 females, ranging in age from 35 to 87 years old, with an average of 61.00 years old. The patients in the control group were treated with normal methods such as shuck test or limb touching. All the patients were operated by the same experienced surgeon. In the experimental group,total hip arthroplasties (THA) were performed on 35 patients with avascular necrosis of the femoral head or femoral neck fracture, and 16 patients were treated with hemiarthroplasty (HA). In the control group, 38 patients received THA and 13 patients received HA. On the anterior-posterior X-ray radiograph, several indexes were measured as follows: the distance of bilateral femoral offset (a), the height from tip of great trochanter to the rotation center of the femoral head (b) and the vertical distance between the top of the minor trochanter and the two tear drops line (c). The leg length discrepancy can be assessed with three parameters as follows: d1, the absolute value of the difference between the bilateral a values; d2, the difference between the bilateral b values; d3, the difference between the bilateral c values. The SPSS 21.0 was applied for the statistical analysis.

RESULTSIn the experimental and control groups, d1 were 4.49 mm and 7.32 mm (P = 0.013); d2 were 2.37 mm and 4.32 mm (P = 0.033); d3 were 3.32 mm and 6.08 mm (P = 0.031). The values of d1, d2 and d3 in the experimental group were significant smaller than those in the control group.

CONCLUSIONThe new measuring tool and method can be used to control the limb length and offset effectively during operation.

Glycyrrhizin acid and licorice flavonoids are the component of Glycyrrhiza uralensis Fisch root that has been used for various medicinal purposes in traditional oriental medicine for thousands of years. Macrophages as a principal component of immune system play an important role in the initiation, modulation and final activation of immune response against pathogens. In the present study, glycyrrhizin acid and licorice flavonoids was investigated the anti-inflammatory effect on lipopolysaccharide (LPS)-induced macrophage cell line of RAW264.7. Well-grown RAW264.7 cells were collected and randomly divided into the blank control group, the LPS(1 mg x L(-1)) group, the dexamethasone (5 mg x L(-1)) with LPS group, the glycyrrhizin acid (400, 80, 16 mg x L(-1)) with LPS group and the licorice flavonoids (200, 40, 8 mg x L(-1)) with LPS group. RAW264.7 cells were cultured in 24-well plates, pre-incubated for 4 h with different concentrations of dexamethasone, glycyrrhizin acid, or licorice flavonoids. Then cells were stimulated for 20 h with LPS. The supernatant of culture medium was collected from each well and determinated the concentrations of cytokines by means of BioPlex mouse cytokines assay. Compared with the control group, the LPS group could significantly induced relatively high levels of granulocyte colony stimulating factor (G-CSF), granulocyte-macrophage colony stimulating factor( GM-CSF), macrophage inflammatory protein-1 alpha (MIP-1α), macrophage inflammatory protein-1 beta (MIP-1β), regulated upon activation normal T cell expressed and secreted factor (RANTES), tumor necrosis factor alpha ( TNF-α), monocyte chemotactic protein 1 (MCP-1), chemokine (C-X-C motif) ligand 1 (KC), eotaxin, interleukin(IL)-1α, IL-1β, IL-3, IL-4, IL-5, IL-6, IL-10, IL-12 (p40), IL-12 (p70), IL-13, and IL-17 secretion (P < 0.05). The glycyrrhizin acid significantly inhibited IL-1β, IL-3, IL-5, IL-6, IL-10, IL-12 (p40), IL-12 (p70), IL-13, Eotaxin and TNF-α secreted by LPS-stimulated RAW264.7 cells (P < 0.05). The expression levels of IL-6 and Eotaxin were observably decreased in the licorice flavonoids with LPS group (P < 0.05). The data presented here suggested that the glycyrrhizin acid and licorice flavonoids modulate various cytokines secreted by macrophages and were important anti-inflammatory constituent of Licorice.

To study the anti-inflammatory activity of glycyrrhizin acid, ligustrazine and puerarin. In the study, the liquichip-based high-throughput synchronous detection technique for 23 inflammatory factors, uniform design, comprehensive weight method were adopted to study the effect of different combined administration of glycyrrhizin acid, ligustrazine and puerarin in inhibiting the expression of lipopolysaccharide (LPS)-induced RAW264. 7 cells and multiple inflammatory cytokines. In the study, the uniform design table U₉ (9³) was adopted to design doses of glycyrrhizin acid, ligustrazine and puerarin. The liquichip technique was used to detect the effect of different combined administration of glycyrrhizin acid, ligustrazine and puerarin on the 23 cytokines expressed in LPS-induced mouse macrophage RAW264. 7 inflammation model. The traditional Chinese medicine component optimization software and the improved least angle regression algorithm were used to analyze the dose-effect relationship among the three components and the cytokine inhibition rate and produce the regression equation. The comprehensive weight method was applied to get the optimal dose ratio of glycyrrhizic acid, ligustrazine and puerarin with highest efficacy of 25:2:13 and verify the optimal dose ratio. The verification results were consistent with the prediction trend, indicating the accuracy of the mathematical model for predicting the experiment. The experimental results showed the multi-target and multi-level efficacies of glycyrrhizic acid, ligustrazine and puerarin and the high anti-inflammatory activity of their combined administration, which provides powerful basis for subsequent drug development.

A Staphylococcus aureus strain, designated zfb, was isolated from a clinical bovine mastitis case of a dairy cow. Staphylococcus aureus zfb can have resistance to methicillin and no lipase contrast by ATCC 25923. The production of the capsule was assessed by the diffuse colonial morphology in serumsoft agar. A mouse infection model was used to determine the LD50 and the invasiveness of SA zfb. The LD50 of SA 25923 to experimental mice was 10-2.5/mL, and the LD50 of SA zfb to experimental mice was 10-4.33/mL. The purpose to detect characteristics of SA zfb makes it an interesting candidate for the preparation and assay of an avirulent mutants against staphylococcal infections and further investigate on pathogenic mechanism.

Objective To explore the relation between the expression of PBMCs IP-10 mRNA and systemic lupus erythematosus.Methods The expression of PBMCs IP-10 mRNA was investigated by RT-PCR semi quantitative method and samples from 46 patients with SLE,20 patients with RA,11 non-SLE patients with renal impairment and 20 healthy volunteers.Results The expression of PBMCs IP-10 mRNA in active SLE group was significantly higher than that in inactive group(P0.05).Serum levels of IP-10 were highly correlated with the expression levels of PBMCs IP-10 mRNA(r=0.897 1,P

Objective To explore different doses of calcium 5-formyltetrahydrofolate(CF)for protecting enteral mucosa after chemotherapy of high-dose methotrexate(HD-MTX) in rats.Methods Sixty of 6 weeks old Wistar rats were divided into 5 groups in random,12 rats every group.Group A:control group,normal sodium(NS) intraperitoneal injection only;Group B to E:after HD-MTX intraperitoneal injection(120 mg/kg),1% CF(CF dose amounts to 1% of total MTX dose) for group B,2% CF for group C,8% CF for Group D and empty for group E.For group B、C and D,CF were intramuscular injected after 12 hours of MTX used,q6h?7 times.Rats were killed after 18 hours of the last time of CF.Morphous of jejunum dissection were observed and length of intestinal villus and depth of crypt were mea-sured.Results For group A,jejunum walls were thick and elastic and intestinal villus were close and orderly.Jejunum walls were congestive,swollen and thin,length of intestinal villus and depth of crypt reduced both in group B to E.These were most obvious in group E,and were secondary in group B.Statistical analysis showed that significant difference in effect existed between group B,C,D,E and group A(Pa0.05).Conclusion MTX can damage in intestinal mucosa of rats,CF can reduce this damage,excessive low doses of CF can't play this role.

Objective To introduce the technique and experience in reconstruction of posterior crueiate ligament-posterolateral comer(PCL-PLC)injuries with only one allograft of Achilles tendon. Methods The instable knees in 12 cases with PCL injury combined with three degree chronic PLC injury were treated with PCL reconstruction under arthroscope and PLC reconstruction through posterolateral arc incision.Single bundle grafts of PCL reconstructions in tibial and femoral tunnels were fixed by resorption screws.Fibular collateral ligament(FCL)and popliteofibular ligament(PFL)were reconstructed with reforming Larson(?)method.All reconstruction grafts only needed one Achilles tendon as donator.Total op- eration time was 130 minutes including 90 minutes of PCL reconstruction and 40 minutes of PLC recon- struction.Gradual weight loading was allowed after six weeks of bracing.Results Follow-up for mean 12 months(5-24 months)indicated that tibial“step off”reduction was 83%(10/12)and posterior drawer test of 0-1~+ 75%(9/12).Dial sign evaluated that normal external rotation angle was 75%(8/12).Nor- real varus stress test at 30?knee flexion accounted for 83%(10/12).Scores of Lysholm,Tegner and HSS were 90.5,5.1 and 84.5,respectively(P＜0.01=.Conclusion Synchronized reconstruction of PCL and PLC injuries with only one Achilles tendon can obtain satisfactory clinical result,with less expense and shorter operation time.
