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.

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.

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.

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.

To study the expression of herpes simplex virus type 2 latency-associated transcript (LAT) open reading frame 1 (ORF1) and its anti-apoptosis function induced by actinomycin D in Vero cells. The recombinant plasmid pEGFP-ORF1 was constructed and transfected into Vero cells, and the expression of ORF1 was identified by RT-PCR. The changes of Vero cells morphology induced by actinomycin D were observed by fluorescence microscopy, Hochest33258 fluorescence staining. Cells viability was evaluated by MTT assay and cells apoptosis rate was detected by flow cytometry. Double digestion and sequencing confirmed the pEGFP-ORF1 was constructed successfully, RT-PCR showed that the target gene was highly expressed in Vero cells. Hochest33258 staining reaveals that Vero cells transfected with pEGFP-ORF1 and induced apoptosis by actinomycin D had no changes in morphology. MTT assay showed that the viabilities of Vero cells transfected with recombinant plasmid pEGFP-ORF1 and induced apoptosis by actinomycin D has no statistically significant difference compared with the untreated normal control group (P > 0.05), but remarkable higher than Vero cells transfected with empty plasmid pEGFP-C2 and induced apoptosis by actinomycin D, the difference was statistically significant (P < 0.05). Flow cytometry assay shows that the cells apoptosis rate had no significant difference between pEGFP-ORF1 group and the normal group, but the cells apoptosis rate ofpEGFP-ORF1 was lower than the pEGFP-C2 group. HSV-2 LAT ORF1 gene can be expressed in Vero cells and can protect Vero cells from apoptosis induced by actinomycin D.

BACKGROUND: Opiate drugs are widely used to control chronic cancer pain, which brings many adverse reactions. Transplantation of sodium alginate-polylysine-alginate microencapsulated bovine adrenal chromaffin cell (BCC) has reported to be used as chronic cancer pain controllers. However, the high price and poor strength of polylysine limited its clinical application. Chitosan is characterized by sufficient resource, low price and good biocompatibility, which is a substitute for polylysine.OBJECTIVE: To study the effect of xenotransplantation of sodium alginate-chitosan-alginate (ACA) microencapsulated BCC on patients with advanced cancer pain.DESIGN, TIME AND SETTING: A retrospective case analysis. All cases were obtained from Department of Oncology, Affiliated Zhongshan Hospital of Dalian University from January 2007 to December 2008.PARTICIPANTS: Totally 10 patients with advanced cancer, including 1 female and 9 males, aged 46-78 years. According to visual algetic mimic scale (VAS), 3 patients suffered moderate pain and 7 cases suffered severe pain.METHODS: Microencapsulation method was applied to encapsulate BCC with ACA membrane and transplant the microencapsulated BCC (5-7)×10~6 into the subarachnoids pace of 10 patients.MAIN OUTCOME MEASURES: The degree of pain release, duration of analgesic effect, as well as adverse reaction.RESULTS: All 10 patients had pain relief rapidly after transplantation in varying degrees. Complete pain relief was shown in 2 cases, medium relief in 1 case, slight relief in 4 cases. Slight irritation of cauda eguina was presented after transplantation, which could disappear within 3-5 days.CONCLUSION: Xenotransplantation of ACA microencapsulated BCC into the spinal subarachnoids pace of patients with cancer pain can produce analgesic effect promptly, significantly, and safely.

Objective To construct rat TRESK gene recombinant adenovirus expression vector.Methods TRESK full-length cDNA was cloned from rat dorsal root ganglion cells and confirmed by RT-PCR and sequencing. pAd/CMV/V5-DEST-TRESK was then constructed under the control of CMV-promotor. DH5α colibacillus was translated and the positive recombinants were subsequently identified by PCR and DNA sequencing. 293T cells were cotransfected and packed to produce adenovirus. Results The titer of virus was tested using Hole-by-dilution titer method. The full length of TRESK from rat dorsal root ganglion cells is 781 bp. It was demonstrated that the DNA sequencing was completely consistent with TRESK sequencing of rat recorded in GeneBank. The PCR amplification of the pAd/CMV/V5-DEST-TRESK gDNA was matched with pAD-GFP blank vector as anticipated. The titer of the concentrated virus was 1.31×109 TU/ml.
