Objective: To evaluate the repair method and its curative effects on defects and joint instability in elderly patients with recurrent soft tissue sarcoma around the knee after wide excision. Methods:Our study included 6 elderly patients with limb sal-vage and effective preoperative chemotherapy. These patients underwent extended resections, including internal or lateral articular cap-sule and collateral ligament excisions. Owing to polyleptic soft-tissue sarcoma around the knee, formed soft-tissue defects, and joint in-stability, collateral ligament and/or partial articular capsule was reconstructed using #5 Ethibond sutures. Simultaneously, soft-tissue de-fects around the knee were repaired by composite-wide pedicled fasciocutaneous flaps or medial head of gastrocnemius muscle flaps of the leg. The maximum flexion angles of the knee (MFKs) were observed and statistically tested before and during surgery, with a fol-low-up period of 6 months. Results: The immediate stability of the joints and complete coverage of the soft tissue defects were achieved during the surgery. The MFKs during preoperative treatment, intraoperative treatment, and six-month follow-up were 115.0° ± 7.8°, 101.7° ± 9.3°, and 104.8° ± 10.2°, respectively, with significant differences between the preoperative and intraoperative MFKs (t=2.68, P<0.05). By contrast, no difference existed between the intraoperative and six-month follow-up MFKs (t=0.55, P>0.05). Conclu-sion:This repair method can be applied to elderly patients with polyleptic soft tissue sarcoma around the knee by using simple, fast, and reliable surgical techniques for the reconstruction, stability, and repair of soft tissue defects in the knee joint.

Objective To determine whether the susceptibility to ischemia-reperfusion injury in aged heart is higher than that in adult heart and,if so,to clarify the mechanisms underlying this change.Methods Wister rats(5-or 20-month-old)were randomly divided into 4 groups(6 animals in each group).The rats were subjected to 30 minutes of myocardial ischemia via ligating the left anterior descending coronary artery,followed by 3 hours of reperfusion(Young-MI/R group and Old-MI/R group);A silk suture around the left anterior descending coronary artery was not ligated in young and old rats(Young-sham group and Old-sham group).Myocardial apoptosis was detected by terminal deoxynueleotidyl transferase biotin-d UTP nick end labeling(TUNEL)staining and caspase-3 activity was detected by using a caspase-3 colorimetrie assay.Nitrotyrosine content,a footprint of in vivo ONOO~-formation,and total NO content were determined by ELISA and chemiluminescence method respectively.Results A significantly exacerbated cardiac reperfusion injury was found in Old-MI/R group as evidenced by increased TUNEL positive myocytes[(19.0?2.1)% vs.(14.6?1.7)%],and increased myocardial caspase-3 activity[(436?35)?mool/mg vs.(340?32)?mol/mg] compared with Young-MI/R group(P＜0.05).Aged hearts had a markedly increased basal NOx level compared with young adult hearts.Marked higher myocardial nitrotyrosine content was found in OId-MI/R group[(7.25?0.18)nmol/g]than that in Young-MI/R group[(4.68?0.15)nmol/g] (P＜0.05).Conclusions In aged hearts,high levels of NO might form highly toxie derivant, ONOO~-,and its subsequent nitrified protein.This may attribute to the increased susceptibility of the aged heart to isehemic-reperfusion injury.

OBJECTIVETo observe the effect of Liuweidihuang Pills in relieving cellphone electromagnetic radiation-induced histomorphological abnormality, oxidative injury, and cell apoptosis in the rat testis.

METHODSThirty adult male SD rats were equally randomized into a normal, a radiated, and a Liuweidihuang group, the animals in the latter two groups exposed to electromagnetic radiation of 900 MHz cellphone frequency 4 hours a day for 18 days. Meanwhile, the rats in the Liuweidihuang group were treated with the suspension of Liuweidihuang Pills at 1 ml/100 g body weight and the other rats intragastrically with the equal volume of purified water. Then all the rats were killed for observation of testicular histomorphology by routine HE staining, measurement of testicular malondialdehyde (MDA) and glutathione (GSH) levels by colorimetry, and determination of the expressions of bax and bcl-2 proteins in the testis tissue by immunohistochemistry.

RESULTSCompared with the normal controls, the radiated rats showed obviously loose structure, reduced layers of spermatocytes, and cavitation in the seminiferous tubules. Significant increases were observed in the MDA level (P < 0.01) and bax expression (P < 0.01) but decreases in the GSH level (P < 0.01) and bcl-2 expression (P < 0.01) in the testis issue of the radiated rats. In comparison with the radiated rats, those of the Liuweidihuang group exhibited nearly normal testicular structure, significantly lower MDA level (P < 0.05), bax expression (P < 0.01), and bcl-2 expression (P < 0.01).

CONCLUSIONLiuweidihuang Pills can improve cellphone electromagnetic radiation-induced histomorphological abnormality of the testis tissue and reduce its oxidative damage and cell apoptosis.

Argyrogramma agnata has been selected as a substitutive host insect for producing Dendrolimus punctatus Cytoplasmic Polyhedrosis Virus (DpCPV). In our experiment, it is very susceptible to DpCPV. The DpCPV produced in A. agnata is designated Aa-DpCPV. The cytoplasmic polyhedra body (CPB), the virion size and the shape of Aa-DpCPV are same as that of its original DpCPV (DpCPV-W1984). The RNA bands of Aa-DpCPV and DpCPV-W1984 all have 10 RNA segments respectively in 3% PAGE, which molecular weights ranged in size from 2.98×106 to 0.66×106 Dalton. Aa-DpCPV has the same strong toxicity as that of DpCPV-W1984 (from D. punctatus) to D. punctatus (Walker) larva. So it can be applied to the pine caterpillar control. The DpCPV yield in A.agnata is 2.5×108CPB/larva.

The 1.23 kb DNA fragment encoding the early protein EP0 of pseudorabies virus (PRV) Ea strain was amplified by PCR technique and cloned into pBluescriptII sk+.Three sequencing plasmids containing the partial fragment of the EP0 gene were constructed and the sequences were obtained by Sanger's sequencing technique. Compared with PRV InFh strain, there were multipile site-mutations and a deleted-mutation in the EP0 gene of PRV strain Ea，and the diversity of amino acid residues also existed.Then, the EP0 gene was inserted into an expression vector, pET-28a, fused into the downstream of the 6ΧHis-Tag in frame, to yield the expression plasmid pETEP0. After induction by IPTG, a high expression of fusion protein was obtained, SDS-PAGE analysis and Western blotting showed that the fusion protein was 62kD and the protein was specific to antisera against PRV Ea strain. This indicated that the EP0 gene be expressed in BL21(DE3) and the expression products have immuno-genicity.

Background There is no effective method to regenerate the optic nerve after injury. It has been recently reported that α-crystallin could promote the survive rate and axon regeneration of retinal ganglion cells (RGCs) effectively. However,the molecular mechanism is not clear. Objective This study was to identify the site of RGCs where the exogenous α-crystallin bind to. Methods RGCs was isolated from retinas of two 2-day-old Long Evans rats and primarily cultured. The positive rate of the RGCs was assessed by counting the number of positive cells for fluorescently-labeled thy1. 1 and cy3 under the fluorescence microscope. The biotinylated exogenous α-crystallin was evaluated by direct coloration and the activity of molecular chaperones was measured by insulin test.After identifying the success of biotinylation along with the activity of molecular chaperones,biotinylated α-crystallin was co-incubated with RGCs and the cells then were reacted to fluorescently labeled avidin for the observation of binding site of exogenous α-crystallin under the laser confocal microscope. Results RGCs of 94% were survived through primary culture. The coloration of biotinylated α-crystallin labeled by the direct coloration method was more intensive, and the value of A450 descended as the decrease of biotinylated α-crystallin concentration,indicating that the α-crystallin was biotinylated successfully. The activity of molecular chaperones of biotinylated α-crystallin was significantly strong but no significant change after being biotinylated after co-incubation of RGCs with biotinylated α-crystallin. Laser confocal microscope examination revealed that co-incubated RGCs with biotinylated α-crystallin showed the red fluorescence on membrane and axon of RGCs rather than cytoplasm and nucleus. The absent response was seen in the control group. Conclusion Exogenous α-crystallin can specifically combine with the membrane of RGCs to play the biological function,but its binding mode and mechanism need further study.
