Objective To investigate the methods and effects of the pedicle modification in free flap which use medial-lower-leg-flap with a healthy limb cross-leg bridging thoracic umbilical flap.Methods From June 2006 to June 2010,twenty-eight cases with a large area of soft tissue defects caused by severe trauma were included in this study.We used The flap was used to repair the wound,the pedicle of the flap was improved which was designed by medial lower leg flap with a healthy limb cross-leg bridging thoracic umbilical flap:thoracic umbilical flap carrying the cross midline side flap.Medial lower leg flap in tongue cutting out and carrying on the medial malleolus perforator.In the processing of bridge-pedicled,we rolled the proximal porting of cross-leg flap,used medial malleolus perforator flap as a posterior wall and used thoracic umbilical flap carrying the cross midline lateral flap as anterior wall.Two portions formed a combined percutaneous tube.The two tile formmed a combined percutaneous tube.Fixing method for operation adopted external fixator which two legs were paralleling.Observation of postoperative flap survival situation,shape,color,elastic,scar contracture,and dysfunction.Results Twenty-eight cases of postoperative all flaps survived.Vascular crisis was appeared in 2 cases after 8 hours.Upon examination that was low blood pressure,low hematocrit.In treatment of transfusion and infusion,crisis mitigated.In 1 case after 12 hours with pain occurred arterial crisis,which was reliefed with analgesia.There were no vascular crisis in other 26 cases.Followed up for 2-20 months,flap had good blood supply,color and good elasticity.The appearance was not bloated and sensory recoverred partly.There was no apparent stiffness in double knee,ankle joint.Conclusion Medial lower leg flap with a healthy limb cross-leg bridging thoracic free flap transplantation for repairing serious soft tissue defects of the leg is clinically proven good means.Based on the improvement of pedicle,it can reduce the risk and complications.At the same time,it can improve the postoperative nursing care effects.It is worthy of popularization and application.

AIM: To investigate the effect of PMA(phorbol 12-myristate 13-acetate) on the expression of CD18 and the mechanism. METHODS: The technique of quantitative RT-PCR analysis was used to measure the expression of CD18 mRNA in U937 cells treated by PMA. RESULTS: PMA could significantly induce CD18 mRNA expression in a dose and time-dependent manner. The induction effects of PMA on CD18 mRNA could be inhibited obviously by Myr (2 ?mol/L), a specific inhibitor of PKC, and APDC, an inhibitor of NF-?B, but not be inhibited by curcumin, a inhibitor of transcriptional factor AP-1. CONCLUSION: PMA enhanced the expression of CD18 via the pathway of PKC. Transcriptional factor NF-?B, but not AP-1, was essential for the gene transcription of CD18 in U937 cells treated by PMA.

OBJECTIVE: To evaluate the function of tubomanometry (TMM) in forcasting the progonosis of acute otitis media with effusion (OME). METHOD: We used the technique of TMM to quantify the degree of eustachian tube (ET) dysfunction in 65 patients with OME. The opening of the ET and the transportation of gas into the middle ear were registered by a pressure sensor in the occluded outer ear after applying the stimulus of a controlled gas bolus into the nasopharynx during swallowing. Three excess pressure values were tested subsequently (30, 40, and 50 mbar). If tube opening was registered, the time of opening in relation to pressure applied was measured. The TMM calculated the opening latency index or index R. An R value of < 1 indicated early opening of the tube at the start of application of the stimulus, which was considered optimal. A value > 1 indicated late opening of the tube occurring after the initial stimulus and was interpreted as suboptimal. Inability to calculate the index R value indicated that the tube was unable to actively open at all. The TMM results, were weighted as follows: no R with 0 points, R > 1 with 1 point and R < 1 with 2 points for the measurements at 30, 40, and 50 mbar, respectively. The points of these three tests were added so the ET score (ETS) ranges from 0 (worst value) to 6 (best value). According to the medical history, the patients were divided into two groups, chronic OME group (defined as positive control group), 30 cases with 38 ears; and acute OME group, 35 cases with 46 ears. The healthy ears of all patients were defined as normal control group, 46 cases with 46 ears. The same regular treatments, including classic medical treatments and intratympanic dexamethasone injections, were used to acute OME group in the following 1-2 months. On the basis of therapeutic effect, acute OME group was subdivided into valid group (26 cases with 33 ears) and invalid group (9 cases with 13 ears). RESULT: The ETS of normal control group was 5.11 ± 1.32 while it was 1.08 ± 1.32 in positive control group. It was found marked differences between the two groups (P < 0.01). The ETS of both valid and invalid subgroup of actue OME group were significantly lower than normal control group (P < 0.01), but in valid subgroup it was significantly higher than positive control group (P < 0.01), and no marked difference was found between the invalid subgroup and positive control group. After treatments, a significant improvement of the ETS was found in both valid and invalid subgroup (P < 0.05) there was no marked difference between valid subgroup and normal control group. But in invalid subgroup it was still significantly lower than normal cohtrol group (P < 0. 01). CONCLUSION TMM could forecast the prognosis of acute OME. Patients with acute OME suffered from ET dysfunction of varied degrees. Those with high ETS could be cured by classic medical treatments and intratympanic dexamethasone injections. But those with poor ETS could not be cured in short period, tube insertion should be considered. If ETS could not be improved by ventilation tube placement, more active treatment, for example, balloon Eustachian tuboplasty (BET), should be used to prevent transforming into chronic OME.

AIM:To evaluate the effects of pilocarpine, brinzolamide and the preservatives of them on corneal epithelial cells and the histopathology of rabbit conjunctiva. METHODS: Fifteen New Zealand white rabbits weighing 1.5 kg to 2.5 kg were randomly divided into three groups. One group with three rabbits served as untreated controls. Pilocarpine 1% and brinzolamide 1% each were administered to the right eyes in one treated group, and the preservatives (chlorobutanol 0.01% in pilocarpine, benzalkonium chloride 0.01% in brinzolamide) to the left eyes. Corneal epithelial damage was evaluated by scanning electron microscopy, and conjunctival specimens were examined under light microscopy. RESULTS: Compared with normal controls, brinzolamide and BAC caused corneal epithelium damage and increased number of inflammatory cells in the conjunctiva, while pilocarpine and the preservative chlorobutanol mainly influenced the corneal epithelium. Brinzolamide produced significantly more damage than pilocarpine (P

Objective To investigate the synergistic anticancer effect of ATO combined with Rad001 on human ovarian cancer cells in vitro and the underlying mechanisms. Methods SKOV3 cells were treated with Rad001, ATO and a combination of Rad001 and ATO, respectively. Cell relative luminescence units, viability, and combination index were tested. The apoptosis was quantified by Flow cytometry. Autophagy and apoptosis associated proteins were measured with immunoblotting. Results Significant decrease in live cell number were observed in cells treated with combination of Rad001 and ATO , compared with single compound treatment (P <0.05). Moreover, a higher rates of autophagy as well as apoptosis were observed in the combination treatment compared with single compound treatment (P < 0.05). Conclusions combination of Rad001 and ATO can result in synergistic cytotoxicity through activation of the excessive autophagy and apoptotic pathway.

AIM: To study the effect of dexamethasone(Dex) on the expression of CD18. METHODS: Quantitative RT-PCR analysis, Northern blotting technique were used to measure the expression of CD18 in U937 cells treated by PMA. RESULTS : Dex could significantly attenuated the effects of PMA in a dose-dependent manner (10 -6 mol/L-10 -10 mol/L). These effects of Dex (10 -7 mol/L) were completely aborted by RU-486 (10 -6 mol/L).CONCLUSION: Dex, via GR, could inhibit CD18 mRNA expression in U937 cells treated by PMA. The effects of Dex might be possibly depended on the counteracting action on the NF-?B.
