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.

OBJECTIVE:To study the effect of HP-β-CD on solubility of 1,8-oxido-p-menthane in volatile oil of magnoliae flos,and optimize the extraction technology of Xinzhi nasal drops. METHODS:Steam distillation method was adopted to extract the volatile oil in magnoliae flos. Using the content of 1,8-oxido-p-menthane in volatile oil of magnoliae flos as index,HPLC was adopted to determine the effects of HP-β-CD with different concentration on solubility of 1,8-oxido-p-menthane in volatile oil of magnoliae flos. Using the comprehensive scores of imperatorin and extract yield as indexes,orthogonal test was used to optimize the amount of ethanol,volume fraction and extraction time in extraction technology of Xinzhi nasal drops. Verification test was car-ried out. RESULTS:50% HP-β-CD aqueous solution can improve the solubility of 1,8-oxido-p-menthane to 7.6 times. The optimal extraction technology of Xinzhi nasal drops was as follow as 10-fold 80% ethanol,extracting twice,1 h every time. In verification test,the average content of imperatorin was 0.078%(RSD=2.01%,n=3),and extract yield was 10.80%(RSD=1.85%,n=3). CONCLUSIONS:HP-β-CD shows good solubilization effect on the 1,8-oxido-p-menthane in volatile oil of magnoliae flos,and the optimized extration technology for Xinzhi nasal drops is feasible.

Objective To compare the clinical effect between CO2-1aser assisted and cold instrument assisted suspension laryngoscopic surgery for vocal fold cyst.Methods From January, 2011 to December, 2014, 72 patients with vocal fold cyst, which diagnosed by strobolaryngoscopy, were randomly divided into CO2-1aser assisted group and cold instrument group.Strobolaryngoscopy, acoustic analysis and perceptual voice analyses were performed on each patient before surgery, 1 month, and 3 months after surgery, respectively.Results All operations were successfully completed.The complete vocal fold cyst resection rate of CO2-1aser assisted group was significantly higher than cold instrument group (29/36, 80.5％ vs 21/36, 58.3％, P ＜ 0.05), especially the left vocal fold cyst (13/16, 81.3％ vs 9/19, 47.4％, P ＜ 0.05).The complete right vocal fold epidermoid cyst resection rate was significantly higher than retention cyst (17/19, 89.4％ vs 11/18, 61.1％, P ＜ 0.05).Two recurrent cases were found in cold instrument group but no recurrent cases in CO2-laser assisted group (0/36, 0％ vs 2/36, 5.6％, P ＞ 0.05).Correlation analysis showed that vocal fold cyst recurrence was related to complete resection rate and has no relation with surgical methods, histopathological types and position.Subjective and objective assessment of voice quality in preoperative, 1-month postoperative and 3-month postoperative were similer between CO2-1aser assisted group and cold instrument group (P ＞ 0.05).Conclusion The CO2-laser assisted suspension laryngoscopic surgery for vocal fold cyst, can increase the surgical precision, reduce the left hand impact, improve the complete resection rate and reduce the recurrence rate.

Objective To investigate the effect of intrathecal (IT) dexmedetomidine on the expression of cAMP response element-binding protein phosphorylation (p-CREB) in spinal dorsal horn in a rat model of bone cancer pain. Methods Sixty-four adult female Wistar rats weighing 200-240 g were randomly divided into 4 groups (n = 16 each): sham operation group (group S); bone cancer pain group (group BP); normal saline group ( group NS) ; dexmedetomidine group (group D) . Bone cancer pain was induced by injecting Walker 2S6 mammary gland carcinoma cell suspension (2 ×106 cells/ml) 10μl into the medullary cavity of the tibia in BP, NS and D groups. Groups S and BP received no IT injection. Croups NS and D received IT injection of NS 10 μl and dexme detomidine 5 μg/kg respectively 7 days after successful establishment of the model. Ten animals were selected from each group at 1 day before IT administration (T0), immediately before IT administration (T1 ) and at 1, 6, 12 and 24 h after IT administration (T2-5 ) and paw withdrawal threshold (PWT) to mechanical stimuli was measured with von Frey filaments. The other 6 rats in each group were sacrificed at T4 and the spinal cord was removed for determination of p-CREB expression in the spinal dorsal horn.Results PWT was significantly decreased at T1-5 and pCREB expression up-regulated at T4 in BP, NS and D groups compared with group S ( P ＜ 0.05) . Compared with group BP, PWT was significantly decreased at T2-5 and p-CREB expression down-regulated at T4 in group D ( P ＜0.03), while no significant change in PWT and p-CREB expression was found in group NS (P ＞ 0.05) .Conclusion IT dexmedetomidine can reduce the bone cancer pain through inhibiting the phosphorylation of CREB in rat spinal dorsal horn.

Objective To investigate the effect of different doses of dexmedetomidine(Dex)on sevoflurane consumption in patients undergoing laparoscopic oophorocystectomy.Methods Eighty ASA Ⅰ or Ⅱ patients aged 25-50 yr with body mass index 18-25 kg/m2 undergoing laparoscopic oophorocystectomy were randomly divided into 4 groups (n =20): control group (group C),low dose Dex group(group DL),medium dose Dex group(group DM) and high dose Dex group(group DH).Normal saline 20 ml and Dex 0.3,0.6,0.9μg/kg was infused iv over 10 min at 10 min before skin incision in groups C,DL,DM and DH,respectively.End-tidal sevoflurane concentration (ETsev) was recorded before Dex administration(T1 ),skin incision(T2 ),immediately after pneumoperitoneum (T3 ),10 min of pneumoperitoneum(T4 ) and the end of surgery (T5 ).Duration of anesthesia,consumption of sevoflurane,emergence time,extubation time were recorded and restlessness at 10 min after extubation was also recorded.The concentrations of blood glucose and corticosteroid were measured by quickly by glucose analyzer and radio-immunity gefore anethesia induction (T0) and at T3,T4,T5 respectively.Results The consumption of sevoflurane per hour,ETsev at T2-5,concentrations of blood glucose and corticosteroid at T3-5 were decreased gradually in groups C,DL,DM and DH ( P ＜ 0.05).The emergence time and extubation time were shorter and the incidence of restlessness was lower in groups DL,DM and DH than in group C ( P ＜ 0.05 ).Conclusion Dexmedetomidine can reduce the consumption of sevoflurane in a dose-dependent manner in patients undergoing laparoscopic oophorocystectomy.
