ABSTRACT

Objective:To evaluate the effect of angiotensin-converting enzyme (ACE) gene polymorphism on dexmedetomidine-induced inhibition of responses to endotracheal intubation in the patients with hypertension.Methods:One hundred and eighty patients with essential hypertension, aged 48-61 yr, weighing 51-66 kg, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, in whom ACE genotype was determined using polymerase chain reaction-restriction fragment length polymorphisms method before operation, were divided into 6 groups ( n=30 each) according to whether dexmedetomidine was applied: DD genotype group (DD group), ID genotype group (ID group), II genotype group (II group), dexmedetomidine plus DD genotype group (DEX+ DD group), dexmedetomidine plus ID genotype group (DEX+ ID group), and dexmedetomidine plus II genotype group (DEX+ II group). Dexmedetomidine 0.8 μg/kg was intravenously infused over 15 min before induction of anesthesia in DEX+ DD group, DEX+ ID group and DEX+ II group.Systolic and diastolic pressure (SP, DP) and heart rate (HR) were measured before dexmedetomidine (T 0), immediately before tracheal intubation (T 1), immediately after tracheal intubation (T 2), and at 1.5 and 5.0 min after tracheal intubation (T 3, 4). The rate-pressure product (RPP) was calculated.The occurrence of myocardial ischemia and cardiovascular responses within 5 min after tracheal intubation was recorded.Blood samples from the internal jugular vein were collected at T 0 and T 2-4, and plasma concentrations of epinephrine (E) and norepinephrine (NE) were determined by high performance liquid chromatography-electrochemical detection assay. Results:Compared with group DD, the SP, DP, HR and RPP were significantly decreased at T 2-4, plasma NE and E concentrations were decreased at T 2, 3, and the incidence of myocardial ischemia and cardiovascular reactions was decreased in group Dex+ DD ( P<0.05). Compared with group ID, SP, DP, HR and RPP were significantly decreased at T 2-4, plasma NE and E concentrations were decreased at T 2, 3, and the incidence of myocardial ischemia and cardiovascular responses were decreased in group Dex+ DD ( P<0.05). Compared with group II, SP, DP, HR and RPP were significantly decreased at T 2, 3, plasma NE and E concentrations were decreased, HR and RPP were decreased at T 4, and the incidence of myocardial ischemia and cardiovascular reactions was decreased in group Dex+ II ( P<0.05). There was no significant difference in the above parameters among group Dex+ DD, group Dex+ ID and group Dex+ II ( P>0.05). Conclusion:ACE gene polymorphism does not affect dexmedetomidine-induced inhibition of responses to endotracheal intubation in the patients with hypertension.

ABSTRACT

Objective To compare the outcomes between interstitial cystitis/bladder pain syndrome (IC/BPS)patients treated with three-drug combination (M blockers + alpha blockers + Amitriptyline) and Sodium hyaluronate intravesical instillation.Methods The patients who came to Second Affiliated Hospital of Nanjing Medical University during October 2014 to September 2015 were investigated if they had IC/BPS.According to the treatment plan,27 patients (group A) received three-drug combination (M blocker + alpha blockers + Amitriptyline)therapy.Thirty-eight patients recelved instillation of sodium hyaluronate (40 mg/50 ml) therapy (group B).Intravesical instillations were performed weekly in the first 6 weeks,and monthly until sixth month.Interstitial cystitis symptom index,interstitial cystitis problem index,overactive bladder symptom score,visual analogue scale/score,the maximum urination and self-rating depression scale were assessed at baseline and the sixth month.Measurement data were expressed as ((x) ±s),t test was used for comparison between groups,and paired t-test was used for comparison of paired data.Results There were 65 patients.Age range was 25-73 years,course of disease (2-99 months),average age (51.4 ± 13.5),average duration (39.8 ± 31.0) months,of which 9 male (13.8%) and 56 female (86.2%) patients.The group A variation of ICSI、ICPI、OABSS、VAS、SDS and maximum urination were 3.7 ± 2.4、1.3 ± 1.5、1.2 ± 1.3、2.1 ± 1.5、3.1 ± 4.5、74.6 ± 52.4,The variation of group B ware 6.8 ± 3.6、5.0 ± 3.8、2.5 ± 1.8、2.8 ± 1.7、8.9 ± 6.4、109.0 ± 81.1.The improvement in ICSI,ICPI,OABSS,SDS of group B were higher than group A (P < 0.05).Conclusion IC/BPS seriously affect the quality of life and the patients are prone to depression.The sodium hyaluronate intravesical instillation therapy could achieve more effect than the three-drug combination therapy.

ABSTRACT

Objective To evaluate the effect of angiotension-converting enzyme (ACE) gene poly-morphism on dexmedetomidine-induced inhibition of responses to extubation in the patients with hyperten-sion. Methods A total of 180 patients with primary hypertension, aged 50-63 yr, weighing 54-69 kg, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, scheduled for elective abdominal surgery under general anesthesia, in whom ACE genotypes were detected using polymerase chain reaction-restriction fragment length polymorphism, were divided into 6 groups (n = 30 each) according to whether dexmedeto-midine was applied: DD genotype group (DD group), ID genotype group (ID group), Ⅱ genotype group (Ⅱ group), dexmedetomidine +DD genotype group (DEX+DD group), dexmedetomidine +ID genotype group (DEX+ID group) and dexmedetomidine+Ⅱ genotype group ( DEX+Ⅱ group). Dexmedetomidine 0. 5 μg·kg-1 ·h-1 was intravenously infused starting from 30 min before the end of surgery until the end of surgery in DEX+DD, DEX+ID and DEX+Ⅱ groups. Immediately before infusing dexmedetomidine (T1 ), at 30 min of dexmedetomidine infusion (T2 ), immediately after extubation (T3 ) and at 1. 5, 5 and 15 min after extubation (T4-6 ), systolic blood pressure, diastolic blood pressure, heart rate and ECG were recor-ded, and rate-pressure product was calculated. The development of myocardial ischemia and responses to extubation was recorded within 15 min after extubation. Results Compared with the baseline at T1 , each parameter of hemodynamics was significantly increased at T3-6 in DD, ID and Ⅱ groups (P<0. 05), and no significant change was found in each parameter of hemodynamics at T2-6 in Dex+DD, Dex+ID and Dex+Ⅱ groups (P> 0. 05). Each parameter of hemodynamics was significantly lower at T3-6 , and the inci-dence of myocardial ischemia and responses to extubation was decreased in group Dex+DD than in group DD and in group Dex+ID than in group ID (P<0. 05). Compared with group Ⅱ, each parameter of he-modynamics at T3-6 and incidence of responses to extubation were significantly decreased in group Dex+Ⅱ, and each parameter of hemodynamics was significantly increased at T3-6 , and the incidence of myocardial ischemia and responses to extubation was increased in DD and ID groups (P<0. 05). There was no signif-icant difference in each parameter of hemodynamics or incidence of myocardial ischemia and responses to extubation among group Dex+DD, group Dex+ID and group Dex+I (P>0. 05). Conclusion ACE gene polymorphism does not affect dexmedetomidine-induced inhibition of responses to extubation in the patients with hypertension.

ABSTRACT

BACKGROUND:The patients with neurogenic urinary incontinence could be cured to restore their urinary storage function through the implant of the suburethral sling made of appropriate materials in a reasonable way. Meanwhile the choice of materials and the safe and effective control of tension are crucial factors. OBJECTIVE:To review the implanted methods, effectiveness and safety of sling made of different materials in the surgical treatment of neurogenic stress urinary incontinence. METHODS:The PubMed database, English database, CNKI database and related English books were retrieved with computer from January 1986 to January 2012 for the articles on the urethral sling material, urethral sling placement methods, efficacy and safety. The key words were“urethral sling, neurogenic, urinary incontinence”in English and Chinese. Final y, 47 articles were included for review according to the inclusion and exclusion criteria. RESULTS AND CONCLUSION:Urethral sling is a safe, handy, and micro-invasive operation, by using autologous fascia or various synthetic materials to implant into the body. The mechanism of neurogenic urinary incontinence is mainly related with the change of bladder function or the insufficiency of urethral sphincter function. However, it is stil a big problem for us to assure the postoperative ability of such patients to store and control urine because of their complicated conditions.
