Objective To evaluate the optimum ratio of medicine dosage for dexmedetomidine mixed with sufentanil used for patient?controlled intravenous analgesia ( PCIA) after Nuss procedure in pedi?atric patients with pectus excavatum. Methods Sixty pediatric patients diagnosed with pectus excavatum, aged 5-12 yr, weighing 18-50 kg, of ASA physical statusⅠorⅡ, scheduled for elective Nuss procedure under general anesthesia, were randomly divided into 3 equal groups using a random number table:different ratios of medicine dosage while dexmedetomidine was added to sufentanil groups ( SD1-3 groups) . Postopera?tive analgesia was as follows: group SD1 received sufentanil 1 μg∕kg + dexmedetomidine 2 μg∕kg; group SD2 received sufentanil 1 μg∕kg + dexmedetomidine 3 μg∕kg; group SD3 received sufentanil 1 μg∕kg +dexmedetomidine 4 μg∕kg. A mixture of tropisetron 0?1 mg∕kg and dexamethasone 0?1 mg∕kg ( in 100 ml of normal saline) was added in each group. The PCA pump was programmed to deliver 0?5 ml with a lockout interval of 15 min and background infusion at 2 ml∕h. The PCA pump was connected immediately after the end of operation, and sufentanil with a dosage of 0?1μg∕kg was used as a rescue analgesic within 48 h post?operatively. The VAS score was maintained below 4. The requirement for rescue analgesics was recorded. The Ramsay sedation scores was recorded at 4, 8, 12, 24 and 48 h postoperatively, and the occurrence of adverse reactions such as nausea and vomiting, bradycardia, over?sedation, respiratory depression, agitation and shivering was recorded within 48 h after surgery. Results No pediatric patients developed nausea and vomiting, respiratory depression, bradycardia, over?sedation, and shivering. No pediatric patients required rescue analgesics in SD2 and SD3 groups. Compared with group SD1 , the requirement for rescue analgesics and incidence of agitation were significantly decreased, and Ramsay sedation scores were increased at 4 and 8 h after operation in SD2 and SD3 groups. Ramsay sedation scores were significantly higher at 4 h after oper?ation in SD3 group than in SD2 group. Conclusion Dexmedetomidine 3 μg∕kg mixed with sufentanil 1μg∕kg is the optimum ratio of medicine dosage when used for PCIA after Nuss procedure in pediatric patients with pectus excavatum.

Objective To investigate the effect of rhubarb and ephedra prescription on the pulmonary function and blood pressure circadian rhythm in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods One hundred and enghty six patients with AECOPD admitted to Department of Integrated Medicine of Harrison International Peace Hospital from December 2013 to Auguest 2016 were enrolled, and they were divided into a control group 90 cases and an experimental group 96 cases by random number talbe method. The patients in control group were treated with conventional therapy, while those in the experimental group were treated with the conventional therapy and additionally rhubarb and ephedra prescription (including rhubarb 6 g, ephedra 5 g, agrimony 15 g, licorice 15 g), taken orally 2 times a day, the therapeutic course in the two groups being 2 weeks. The diference of blood gas analysis, pulmonary function indexes, dyspnea score (mMRC) and ambulatory blood pressure monitoring were compared before and after treatment in the two groups.Results Compared with before treatment, the pH value, arterial partial pressure of oxygen (PaO2), forced vital capacity (FVC), one second forced expiratory volume (FEV1), FEV1/FVC of the two groups were significantly increased after treatment, while the arterial partial pressure of carbon dioxide (PaCO2) and mMRC score were significantly lowered, and the changes in the experimental group were more significant than those in the control group [pH: 7.40±0.04 vs. 7.37±0.03, PaO2 (mmHg, 1 mmHg = 0.133 kPa): 81.09±12.54 vs. 76.27±12.20, PaCO2 (mmHg): 48.01±8.27 vs. 51.91±8.37, FVC (L): 2.37±0.39 vs. 2.13±0.45, FEV1 (L): 2.08±0.38 vs. 1.87±0.41, FEV1/FVC: (69.01±12.04)% vs. (64.02±11.81)%, mMRC: 2.02±0.76 vs. 2.40±0.87, allP < 0.05 orP < 0.01]. Based on the percentage of blood pressure circadian value difference, the blood pressure circadian rhythm was divided into dipper type, non dipper type, super dipper type and anti dipper type, 24.2% patients were of dipper type and 75.8% patients were of non dipper, super dipper and anti dipper types. There was no significant difference in daytime systolic blood pressure (dSBP) between patients with super dipper and dipper types (P > 0.05),and the dSBP (mmHg) in patients with non dipper type was significantly higher than that in patients with dipper, super dipper and anti dipper types (131.55±5.08 vs. 117.78±4.47, 118.26±4.24, 113.37±3.97, allP < 0.05); the daytime diastolic blood pressure [dDBP (mmHg)] of anti dipper, non dipper type, dipper type, super dipper type increased in turn (respectively, 63.27±2.80, 70.24±3.82, 73.98±2.61, 82.96±4.52, allP < 0.05); the night SBP (nSBP) of anti dipper type was the highest (127.38±4.98) mmHg, and the nSBP of super dipper type was the lowest (89.07±3.81) mmHg; the night DBP (nDBP) of dipper type was lower than that of non dipper, anti dipper and super dipper types (mmHg: 63.57±1.37 vs. 68.86±2.12, 67.15±1.56, 67.89±2.04, allP < 0.05). After treatment, the proportion of patients with dipper type [66.7% (64/96) vs. 54.4% (49/90)], no dipper type [11.5% (11/96) vs. 8.9% (8/90)], and super dipper type [5.2% (5/96) vs. 2.2% (2/90)] in experimental group was significantly higher than that in the control group, the proportion of patients with anti dipper type [16.7% (16/96) vs. 34.4% (31/90)] in experimental group were significantly lower than those in the control group (allP< 0.05).Conclusion The Rhubarb and ephedra prescription can obviously improve the blood gas analysis indexes, pulmonary function and blood pressure rhythm in patients with AECOPD.

AIM: To identify the down-regulated genes in adult rat cardiac fibroblasts (CF) stimulated with angiotensin Ⅱ (AngⅡ). METHODS: Suppression subtractive hybridization (SSH) was performed between the CF stimulated by AngⅡ (driver) and unstimulated CF (tester) to generate subtractive cDNA library. The library was screened with dot blots hybridization to further verify the differentially expressed cDNA clones. Partial positive clones were sequenced and BLAST analyzed. RESULTS: Seventeen down-regulated genes related to intracellular signal transduction, transcriptional repression, deposition of fibrous matrix and cellular cytoskeletal rearrangement, and 4 new expression sequence tags (EST) were acquired. CONCLUSION: SSH is a powerful technique with high sensitivity for the detection and clone of down-regulated genes expressed in CF induced by AngⅡ, which is helpful to clarify the mechanism of cardiac remodeling.

To investigate the contamination conditions of Campylobacter spp.in duck production chain and its antimicrobial resistance,virulence gene distribution,samples were collected at the duck slaughterhouse according to GB 4789.9-2014.Triplex PCR assay was applied to identify the species of Campylobacter and the recovered Campylobacter strains were tested for the antimicrobial susceptibility against 8 kinds of antimicrobial agents using a broth microdilution method,the susceptibility results were determined according to the NARMS criteria (2011).Subsequently,4 virulence genes were detected by PCR method.The result showed that 187 Campylobacter isolates were obtained from 489 samples,including 160 C.jejuni,130 C.coli and 10 unidentified Campylobacter isolates.The total isolation rate of Campylobacter was 38.24％.The prevalence of Camnpytobacter before slaughtering,at depilation stage,evisceration stage and duck products was 76.33％,5.62％,24.00％,and 0％,respectively.The Campylobacter isolates were most frequently resistant to tetracycline (95.72 ％),followed by resistance to clindamycin(90.91％),the resistance rate of azithromycin (63.64％) was in the middle,the resistance rates of ciprofloxacin(31.02％),gentamicin(34.76％),nalidixic acid (37.43 ％),erythromycin (41.18 ％),chloramphenicol (41.18％) were relatively low.The multi-drug resistance was common among Campylobacter isolates with a rate of 72.19％.The prevalence of adhesion-associated gene cadF,flagellin gene flaA,invasion associated protein gene iamA,toxin regulation gene cdtB was 100％,80.75 ％,71.12％ and 94.65％,respectively.The results indicated that the Campylobacter contamination occurred in the slaughtering procedures of duck,and the antimicrobial resistance of Campylobacter isolates was relatively serious.In addition,the virulence-associated genes were detected widely among Campylobacter isolates.Therefore,the supervision of antimicrobial agents using at rearing stage should be strengthened,along with health management in duck production chain.

Objective:To investigate the preoperative diagnostic value of 99Tc m-methoxyisobutylisonitrile (MIBI) planar imaging and SPECT/CT imaging for primary hyperparathyroidism (PHPT), and analyze the relevant factors affecting the imaging results. Methods:From June 2016 to September 2019, a total of 62 patients (15 males, 47 females, age range: 27-80 years) confirmed as PHPT by postsurgical pathology in Affiliated Hospital of Qingdao University were retrospectively enrolled. The diagnostic efficacies of 99Tc m-MIBI planar imaging and SPECT/CT imaging were compared using χ2 test. The differences of preoperative serum parathyroid hormone (PTH), Ca and the maximum diameter of lesion between the positive and negative groups of planar imaging were analyzed using independent-sample t test and Mann-Whitney U test. The region of interest (ROI) method was applied to calculate the uptake ratio of lesions to normal tissues at the early phase (T/Ne) and delayed phase (T/Nd) in positive cases of planar imaging. Pearson or Spearman correlation analysis was used to evaluate the correlation of T/Ne, T/Nd with preoperative serum PTH, Ca and the maximum diameter of lesion. The receiver operating characteristic (ROC) curves of preoperative serum PTH, Ca and positive planar imaging were drawn and the cut-off values were obtained. Results:The sensitivity of planar imaging and SPECT/CT imaging was 69.35%(43/62) and 87.10%(54/62) respectively ( χ2=5.729, P=0.017). The preoperative serum PTH, Ca levels and the maximum diameter of lesion in patients with positive planar imaging (253.32(107.00, 331.70) ng/L, 2.78(2.51, 2.87) mmol/L, (2.01±0.88) mm) were higher than those with negative planar imaging ((111.86±44.29) ng/L, (2.59±0.21) mmol/L, (1.42±0.55) mm; z values: -2.802, -1.978, t=3.300, all P<0.05). T/Ne was positively correlated with preoperative serum PTH ( rs=0.511, P<0.001) and the maximum diameter of lesion ( r=0.381, P=0.012), and T/Nd was positively correlated with preoperative serum PTH ( rs=0.538, P<0.001), Ca ( rs=0.348, P=0.022) and the maximum diameter of lesion ( r=0.463, P=0.002). The area under the ROC curve between preoperative serum PTH, Ca and planar imaging was 0.725 and 0.646, respectively. Preoperative serum PTH had a better predictive value with the optimal cut-off value of 150.4 ng/L. Conclusions:Preoperative serum PTH, Ca and the maximum diameter of lesion are positively correlated with 99Tc m-MIBI uptake in PHPT patients with positive planar imaging results. When preoperative serum PTH is lower than 150.4 ng/L, planar imaging is prone to false negative. SPECT/CT imaging has a significant value in preoperative diagnosis and the combination of PTH and CT can improve the positive rate.

Objective To investigate the effect of section of pancreatic envelope combined with vacuum sealing drainage under laparoscopy on inflammatory mediators of patients with early severe acute pancreatitis (SAP). Methods Forty-two SAP patients were admitted to Foshan Hospital of Traditional Chinese Medicine in Guangdong Province from January 2008 to December 2016. That 22 patients underwent pancreatic membrane incision and vacuum sealing drainage under laparoscopy was in the experimental group, and that 20 patients underwent the routine pancreatic membrane incision and double tube drainage was in the control group. The venous blood was collected, the levels of C-reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were measured before and after operation for 1, 3, 7 and 14 days, and the clinical therapeutic effects were observed in the two groups. Results With the prolongation of therapy, the levels of CRP, IL-6 and TNF-α were decreased continuously in both groups, the degrees of decrease of above indexes in experimental group were more significant than those in the control group, and the differences in these indexes between the two groups were statistically significant [CRP (mg/L): 1 day was 203.80±25.12 vs. 271.79±60.41, 3 day was 117.26±19.70 vs. 174.53±42.37; IL-6 (ng/L): 1 day was 40.63±3.38 vs. 57.10±11.46, 3 days was 23.14±3.51 vs. 46.87±10.69; TNF-α (ng/L): 1 day was 23.91±10.42 vs. 36.73±15.90, 3 days was 19.13±8.34 vs. 32.58±15.81, all P < 0.05]. There were no statistical significant differences in the levels of above indexes on 7 days and 14 days after treatment between the two groups (all P > 0.05). The therapeutic efficacy of the experimental group was significantly higher than that of the control group [95.45% (21/22) vs. 90.0% (18/20), P < 0.05]. Conclusion Under laparoscopy, pancreatic envelope incision combined with vacuum sealing drainage performed for early SAP patients can control the body inflammation more rapidly, reduce complications and shorten the disease course.

Objective To investigate the impulsivity and aggressiveness characteristics of patients with hepatolenticular degeneration (HLD) and its relationship with brain structure.Methods The Chinese version of the Barratt impulsiveness scale,11 version (BIS-1 1-C) and Buss-Perry aggression questionnaire (BPAQ) were assessed in 78 patients with hepatolenticular degeneration(HLD group) and 86 normal adults (health control group).HLD patients were examined by 3.0T magnetic resonance imaging (MRI).The differences in impulsivity and aggressiveness of the two groups were compared,and the relationship was analyzed between impulsivity,aggressiveness and different brain structures in patients with HLD.Results The total impulsive score,unplanned factor score,the total aggressive score and anger factor score of patients with cerebral HLD (61.74±9.82,26.08±5.06,82.71 ± 15.92,20.06± 5.74,respectively) were higher than those in patients with hepatic HLD (56.73±7.11,23.02±4.20,72.84± 11.15,16.64±5.01,respectively),and health control group(52.19±7.53,21.50± 3.93,64.64±9.83,14.27 ±4.38,respectively),and the differences were significant (F=3.193,4.646,11.830,8.270,all P＜0.05).Total impulsive score was positively correlated with aggressive score and physical aggression in HLD group(r=0.299,0.290,both P＜0.05).Unplanned score was positively correlated with aggressive total score (r=0.324) and physical aggression (r=0.320) in HLD group (P＜0.05).Frontal lobe injury was the influencing factor of total impulsive score(B=10.263,95％CI=0.467-19.946,P=0.008),attention score(B=2.837,95％CI=0.382-5.600,P=0.010) and unplanned factor score (B=3.977,95％ CI=0.848-8.502,P=0.046).Thalamus injury was the influencing factor of aggressive total score and its factor score.Caudate nucleus injury was the influencing factor of aggressive total score (B=10.030,95％ CI=3.351-18.039,P=0.017) and physical aggression score (B =4.432,95％ CI=1.193-7.729,P=0.016).Conclusion Patients with HLD have higher impulsive and aggressive tendencies,which are mainly manifested in unplanned impulsive and anger tendencies.Brain injury may be an important factor affecting impulsiveness and aggression in patients with HLD.Impulsiveness is related with frontal lobe injury and aggression to thalamus and caudate nucleus injury.Impulsiveness and aggressiveness in patients with HLD are not caused by damage to isolated brain areas,but are related to damage to multiple brain areas.
