Objective To investigate the CT features of mesenteric lymph nodes in patients with active Crohn’s disease.Methods The CT findings in 54 patients with active Crohn's disease proved by histology were analyzed,and the anatomic distribution,size, number,shape and enhancement ratio (ER)of the mesenteric lymph node were assessed.Results Mesenteric lymphadenopathy in 38 patients (70.4%)was found with a total number of 242,83.5%(202/242)of whom were located at the mesenteric root and 16.5%(40/242) at mesenteric edge.The size of the lymph nodes at the mesenteric root was larger than that at the mesenteric edge (8.57 mm±2.26 mm versus 5.38 mm±0.1 9 mm,the mean maximum short diameter),and 73.6% (1 78/242 )of the lymph nodes were oval in shape.The lymph nodes showed significant enhancement after contrast injection with an ER of 0.53 ±0.09.Conclusion Active CD often leads to mesenteric lymphadenopathy,which is more obvious at the mesenteric root.

AIM:To study the effect of different surgeries for vision and postoperative complications in leprosy patients with lagophthalmos.METHODS:A retrospective analysis.Totally 68 leprosy patients (97 eyes) with lagophthalmos were selected who treated with different surgeries during May 2007 to September 2015 in our sanatorium.The surgeries included nylon thread correction surgery, tarsorrhaphy, temporalis transposition surgery.We observed and compared the best corrected visual acuity(BCVA) and the rate of postoperative complications, such as epiphora, lacrimal duct injury, hard to open eyes, infection at the inner and lateral canthus and scar formation of lacrimal apparatus.RESULTS:The effect on BCVA of patients treated with nylon thread correction surgery and tarsorrhaphy:the preoperative and postoperative BCVA was significantly different of the two groups (Z=-4.193,-4.213;P<0.05);the preoperative and postoperative BCVA was not significantly different of the patients underwent temporalis transposition surgery (Z=-1.532, P >0.05).The postoperative complications:(1) epiphora:there was 91% in patients underwent nylon thread correction surgery, 89% in patients underwent tarsorrhaphy, 59% in patients underwent temporalis transposition surgery, the difference was statistically significant (χ2=12.198, P<0.05);(2) lacrimal duct injury:there was 66% in patients underwent nylon thread correction surgery, 95% in patients underwent tarsorrhaphy, 41% in patients underwent temporalis transposition surgery, the difference was statistically significant (χ2=22.415, P<0.05);(3) hard to open eyes:there was 56% in patients underwent nylon thread correction surgery, 55% in patients underwent tarsorrhaphy, 22% in patients underwent temporalis transposition surgery, the difference was statistically significant (χ2=8.795, P<0.05);(4) infections:there was 84% in patients underwent nylon thread correction surgery, 3% in patients underwent tarsorrhaphy, 11% in patients underwent temporalis transposition surgery, the difference was statistically significant (χ2=60.858, P<0.05).CONCLUSION:There are certain clinical efficacy for lagophthalmos caused by leprosy after surgery, especially patients after temporalis transposition surgery can close eyes by oneself.And their vision does not change significantly, which suggests that this surgery may prevent exposure injury for cornea.But the iatrogenic injury, the vision decrease in patients underwent other surgeries and the ocular tissue damage, such as epiphora, lacrimal duct injury, hard to open eyes, infection at the inner and lateral canthus and scar formation of lacrimal apparatus should be pay more attention to.

ObjectiveTo find out the electroencephalogram(EEG)change of the children with language retardation.MethodsThe EEG change and prognosis of 78 cases of language retardation children were analysed and compared with normal ones.ResultsThe EEG abnormal rate of language retardation was 69.3%,while that of the normal children was 10%(P<0.001).Conclusions The EEG is helpful to understand the developmental status of brain functions.

AIMTo analyze the response factors of different quinolone antibiotics detected by evaporative light-scattering detector (ELSD).

METHODSThe response factors of five different quinolones (enoxacin, levofloxacin, ciprofloxacin, lomefloxacin and gatifloxacin) detected by ELSD were determined by using a YMC-Pack ODS-AM cloumn (150 mm x 4.6 mm ID, 5 microns) as analytical column and 0.5% triethylamine (adjusting pH 2.5 with trifluoroacetic acid)-acetonitrile (48:12) as mobile phase at a flow rate of 0.6 mL.min-1, the temperature of the drift tube was set at 117 degrees C, and the flow of carrier gas at 3.0 L.min-1. Detector responses (A) and the amount of injection of each substance (m) were fitted to the logarithmic regression: log A = b log m + log a.

RESULTSThe linear regression equation obtained were: enoxacin: Y = 1.0799X + 2.7611, r2 = 0.9996; levofloxacin: Y = 1.0913X + 2.7235, r2 = 0.9997; ciprofloxacin: Y = 1.0828X + 2.7523, r2 = 0.9994; lomefloxacin: Y = 1.0891X + 2.7391, r2 = 0.9993; gatifloxacin: Y = 1.0878X + 2.7392, r2 = 0.9995. The differences between them were negligible.

CONCLUSIONDifferent quinolones can give the same responses with ELSD detection. So, the HPLC-ELSD methods can be applied to the determination of new substances by using another substance as reference.

Objective Gastrointestinal rehydration is a simple and effective method in treatment of burn shock during war-time, fire disaster and other harsh conditions , and practice has proved the exact curative effect of HCO 3 salt sugar liquid .This article was to investigate the effect of pyruvate-enriched oral rehydration solution ( Pyr-ORS ) on intestinal mucosal blood flow ( IMBF ) , activity of Na +-K+-ATPase and intestinal absorption rate during en-teral resuscitation of a 35% TBSA third-degree scald in rats . Methods 90 male rats were randomly divided into 5 groups: scald without fluid resuscitation ( S group ); sham scald resuscitated with HCO3 salt sugar liquid ( SS HCO3 group ); sham scald resuscitated with Pyr-ORS ( SS Pyr-ORS group ); scald resuscitated with HCO 3 salt sugar liquid (S HCO3 group); scald resuscitated with Pyr-ORS (S Pyr-ORS group) (n=18).Each group was divided into 2 subgroups of 1.5 and 4.5 h after scald injury.Intestinal absorption rate of water and Na +, IMBF and activity of Na +-K+-ATPase were detected on each group . Results Compared with shame scald groups , the intestinal absorption rates of water and Na +decreased ob-viously in scald groups with fluid resuscitation (P<0.05);at 1 h after scald injury, the intestinal absorption rates of water and Na +in S Pyr-ORS groups were both higher than those in S HCO 3 groups(P<0.05).Compared with shame scald groups , IMBF and activity of Na+-K+-ATPase at 1.5 and 4.5 h after scald injury decreased obviously in scald groups with fluid resuscitation (P<0.05); at 1.5 and 4.5 h after scald injury, IMBF in S Pyr-ORS groups (95.250 ±5.096/112.765 ±7.215) were greater than those in S HCO3 group (80.764 ±7.852/94.671 ±8.469), which was of statistical significance (P<0.05). Conclusion Pyr-ORS is a simple and effec-tive method in treatment of burn shock during wartime , fire disaster and other harsh conditions .

Objective:To compare the Alzheimer's disease model in two species of mice by intracerebroventricular injection of β-amyloid peptide 25-35(Aβ_(25～35)).Method:The step down test and Morris water-maze were used to investigate the influence of the mice's learning and memorizing ability after intracerebroventricular injection of β-amyloid.Results:Normal Kunming mice and BALB/c mice had no significant difference in step down test, but the space cognitive ability of Kunming mice was better than that of BALB/c mice. The learning response in step-down test and Morris water-maze is no influence in male, female BALB/c mice and female Kunming mice. Marked differences were observed in male Kunming mice in acquisition, performance and reversal of a place learning response in a Morris water-maze.Conclusion:The male Kunming mice is much better than female Kunming mice and male, female BALB/c mice in preparing Alzheimer's disease animal model by intracerebroventricular injection of Aβ_(25～35), and is the most suitable animal in this experiment.
