Sensory, chemical, microbiological quality and bacterial flora on fresh Pseudosciaena crocea were qualitatively and quantitatively investigated. The results showed that total viable counts and total volatile basic nitrogen reached 5. 51?0. 25Log10cfu/g, 7. 84?2. 25mg/100g respectively. 279 strains of bacteria were isolated and 84.2% of them were gram negative bacteria, a small percentages of gram positive bacteria were detected (6. 1% ) . The predominant bacterial floras were composed of Enterobacteriaceae (14. 7% ), Aeromonas spp. (12. 5% ), Acinetobacter spp. (11. 5% ) and Moraxella spp. (11. 1% ) . A few percent of Pseudomonas spp. , Stenotrophomonas maltophilia and other bacteria were also found. The high number of Enterobacteriaceae showed that bacterial contamination on Pseudosciaena crocea, was mainly from cultural water field and polluted seriously by non-borne bacteria, and it should be paid attention to.

OBJECTIVETo investigate the method of medial transposition of the radial nerve in plate fixation of lower segment fracture of humerus.

METHODSFrom January 2010 to December 2013,31 patients with medial transposition of the radial nerve in plate fixation of lower segment fracture of humerus, including 18 males and 13 females ranging in age from 26 to 58 years old with a mean of 37 years old. The time between injury and operation was 1 to 8 days with an average of 4.5 days. According to AO classification, 7 fractures were type A1, 3 fractures were type A2, 6 fractures were type A3, 2 fractures were type B1, 4 fractures were type B2, 2 fractures were type B3, 4 fractures were type C, 3 fractures were type C2. No patients had any signs of radial nerve injury. The results were evaluated with DASH (disability of arm-shoulder-hand) Questionnaire by the American Academy of Orthopedic Surgeons (AAOS) which 0 indicated normal upper extremity function, and 1 to 100 indicated varying degrees of damage to the function of the upper extremties.

RESULTSThere was no neurologic complication or postoperative wound infection in this series. The followed-up period ranged form 8 to 15 months (means 11 months) postoperatively. The clinical outcomes were evaluated with DASH Questionnaire, the score before operation was 76.2±11.8, the final follow-up score was 8.2±7.4, the final follow-up score was significant higher than before operation (P<0.01). The function of the upper extremities recovered satisfactorily.

CONSLUSIONThe method of medial transposition of the radial nerve in plate fixation of lower segment fracture of humerus can avoid iatrogenic radial nerve injury effectively.

Objective To study the hydrogen sulfide productivity by mononuclear cells in patients with atrial fibrillation (AF). Methods Mononuclear cells were extracted from peripherial blood of 60 AF patients and 30 healthy controls. Modified methylene blue method was used to evaluate the hydrogen sulfide productivity of mononuclear cells. Results Hydrogen sulfide productivity of mononuclear cells from AF patients was 92.5%higher than that from control [10.63 (8.21~14.37) μmol/(min.g protein) vs 5.52 (4.42~8.50) μmol/(min.g protein)]. Hydrogen sulfide productivity of mononuclear cells was correlated with the left atrial transverse diameter (r = 0.276,P < 0.01), while no significant correlation was found between hydrogen sulfide and left ventricular end-diastolic diameter , left atrial anterior posterior diameter , C-reaction protein etc. Conclusion Hydrogen sulfide productivity of mononuclear cells from AF patients is promoted.

Aim To study the effect of high salt diet during pregnancy on the development of renal vessels in offspring rats and its mechanism.Methods Natural pregnant Sprague-Dawley rats were randomly divided into high-salt group and control group.The pregnant rats in the high-salt group were given high-salt diet of 8% NaCl content , while the control group normal diet with 1% NaCl content.In both groups, pregnant rats were given normal drinking water.After delivery, all mothers returned to normal diet and all neonatal rats were breast-fed until one month old.The adult male off springs were used as experimental animals.The vessel tone of renal interlobar arteries and electrophysiological behavior of single vascular smooth muscle cells (VSMCs) were detected respectively.Results The contractile response of renal arteries to phenylephrine(Phe) in high-salt group was stronger than that in the control group(P<0.05).The effect of protein kinase C(PKC) non selective blocker GF109203X on Phe-induced contraction in two groups also showed significant difference(P<0.05).In electrophysiology experiments, Phe inhibited high-conductance Ca2+-activated K+ channel(BK channel) currents in renal arteriolar smooth muscle cells in two groups, and the inhibitory effect was more pronounced in high-salt offsprings (P<0.05).GF109203X could eliminate the response of Phe on BK currents in both groups(P>0.05).Conclusions High-salt diet during pregnancy could increase the sensitivity of renal interlobar arterial contractile response to Phe in adult male offsprings, which is associated with PKC-mediated BK channels pathway.Maternal high-salt diet during pregnancy may increase the risk of renal vascular diseases in adult offsprings.

Objective To explore a new surgical approach for the renovation of laryngotracheal stenosis. Methods the anatomical structures of the anteroventral portion of the digastric muscle along with the blood supply, innervation and periosteal coverage of the mandibular were investigated by observing 23(46 sides) cadaver. Results The anteroventral portion of the digastric muscle rise from the fossae digastrica at the angle of 30.4°±3.5°. Its length was (4.8+0.7) cm and the periosteal coverage averaged (111.6+28.2) mm2. The puncta of rami digastricus stats (2.4+0.7) cm from the arteriae submentalis. Mylohyoid nerve together with rami digastricus enters the muscular tissue. Conclusion Designed with reference to sternocleidomastoid clavicular periosteal flap, the periosteal flap of the anterovent of the digastric muscle-mandible may offer a new way for largngotracheal renouation.
