Objective To study the protective effect of pure carbachol or combined with dietary fiber on intestinal mucosal barrier of rats after diffuse brain injury (DBI).Methods An adult male Wistar rat model of DBI was reproduced by gravitational shock method. The rats injured and survived after resuscitation were divided into three groups: model group (n = 40), carbachol group (n = 40) and carbachol combined with dietary fiber group (combined group,n = 32). In addition, a control group was established by simply an incision performed on the scalp, and the rats could drink freely (n = 5). In the experimental groups, 2 hours after resuscitation the rats began to receive gavage, 6 hours once, the liquid amount 15 mL/kg should be assured in every 6 hours, and if insufficient, normal saline was supplemented. In model group, normal saline 90 mL/kg was given, in carbachol group, carbachol 300μg/kg was administered and in combined group, carbachol 300μg/kg combined with dietary fiber 60 mL/kg was supplied. At 3 (combined group being excluded), 6, 12, 24 and 48 hours after resuscitation, the rats were anesthetized to collect samples and detect the plasma levels of D-lactate and activity of diamine oxidase (DAO) respectively, and the changes of villus height of small intestine were examined by a light microscope.Results The plasma D-lactate levels and the activities of DAO at any time point in the experimental groups were significant higher than those in control group (allP < 0.01). Along with the prolongation of time, the levels of plasma D-lactate and DAO activities in carbachol and carbachol plus diatary fiber groups were gradually lower than those of the model group, and at 48 hours after injury they reached their valley values [D-lactate (ng/L): 6.32±0.79, 7.46±1.67 vs. 17.65±1.53, DAO activity (kU/L): 0.76±0.01, 0.86±0.01 vs. 2.23±0.15]. Under light microscopy, compared with control group, the villus height of small intestinal mucosa at any time point in any experimental group was gradually lowered, and reached the valley values at 12 hours, then gradually increased , and peaked at 48 hours, the villus height in carbachol group and combined group was higher than that in model group (μm: 265.36±10.20, 261.54±10.38 vs. 247.51±9.39, bothP < 0.05).Conclusion When only carbachol is administered into the rat intestine early after diffuse brain injury in rats, beginning from 6 hours after injury, the protective effect of intestinal mucosal barrier is shown, representing decrease of plasma D-lactate level and DAO activity, amelioration of intestinal mucosal damage and protection of intestinal mucosal barrier; under the same above situation, the carbachol combined with dietary fiber was applied, showing the similar above carbachol protective effects.

OBJECTIVE:To evaluate the curative efficacy of Yixinshu capsule(YXSC)for patients with chronic heart failure(CHF)and its effects on plasma levels of angiotrnsionⅡ(Ang Ⅱ)and tumor necrosis factor-alpha(TNF-?).MET-HODS:60 patients with CHF were randomly assigned to either treatment group(n=30)or control group(n=30):the control group received conventional symptomatic treatment with western medicines including anti-infection therapy,relieving airway obstruction,continuous low-flow oxygen inhalation,cardiac and diuretic therapy,vasodilator,correcting acid-base imbalance and electrolyte disturbances etc;the treatment group received YXSC in combination with the above conventional symptomatic treatment.Plasma levels of AngⅡ and TNF-? in two groups before and after treatment were detected;and the cardiac function and the indexes of echocardiography(LVEF,A/E)of all cases were recorded in detail before and after treatment.Meanwhile,10 healthy subjects served as normal control.RESULTS:After treatment,plasma levels of AngⅡ and TNF-? in both group decreased remarkably(P

Objective By using digital three-dimensional (3D) model of abdominal and pelvic vessels to investigate the relationship between the angle/position of the bifurcation of bilateral common iliac arteries and the length of the common iliac artery, thus to guide the endovascular interventional catheterization manipulation. Methods A total of 439 patients, who received abdominal and pelvic CTA at authors’ department during the period from Sep. 2011 to May 2013, were included in this study. By using digital 3D reformation technique, the 3D model of the abdominal and pelvic vessels as well as the lumbosacral vertebrae was established in all patients. With the help of mimics and geomagic software the angles between the left and right common iliac arteries and the lengths of common iliac arteries were determined, and the lumbar vertebra corresponding to the bifurcation of common iliac arteries was recorded. Using statistical software, the relationship between the bifurcation angle of bilateral common iliac arteries and the corresponding lumbar vertebra as well as the length of common iliac arteries was analyzed. Results The digital 3D model of the abdominal and pelvic vessels as well as the lumbosacral vertebrae was successfully reconstructed in all 439 patients. Both the angle between the left and right common iliac arteries and the corresponding lumbosacral level of bifurcation angle were clearly demonstrated on the model. The average angle was 49.1° ± 12.4°. The bifurcation was located at L3 -L4 level in 38 cases, at upper one-third level of L4 in 63 cases, at middle one third level of L4 in 89 cases, at lower one-third level of L4 in 135 cases and at L4 -L5 level in 114 cases. The average length of the left and right common iliac artery was (45.6 ± 15.6) mm and (43.3 ± 15.4) mm respectively. Pearson correlation analysis indicated that a negative correlation existed between the angle and the position level of the left and the right common iliac artery (r = -0.172, P< 0.05), and a negative correlation also existed between the angle and the length of the common iliac artery (left: r = -0.171, P<0.05; right: r = -0.164, P < 0.05). Conclusion The lower the opening position of the left and right common iliac artery is, and the bigger the intersection angle is, the shorter the length of corresponding common iliac artery will be. In this case, catheterization via femoral artery to contralateral iliac artery is a short path, and the catheterization procedure is easy to manipulate with higher success rate. On the contrary, the catheterization will be difficult, and the use of loop-technique will be needed. The digital 3D model of the abdominal and pelvic vessels as well as the lumbosacral vertebrae can help select the optimal catheterization path.

Objective To observe the protection of carbachol on intestinal barrier function in patients with trauma. Methods A prospective randomized controlled trial was conducted. Seventy patients after trauma with a definite diagnosis of multiple organ dysfunction syndrome(MODS)from Department of Critical Care Medicine in Hebei United University Affiliated Hospital were included. According to random number table,the patients were divided into a carbachol treatment group(37 cases)and a mosapride citrate treatment group(33 cases),and all the patients in the two groups were treated by antibacterial drugs,supportive agents for organ function,surgery, etc symptomatic treatment. Based on the conventional treatment,in the carbachol treatment group,carbachol was administered through a stomach tube at the dose of 0.2 mg/kg,twice a day,and the dose was doubled if no exhaust or defecation persisted for 3 days after treatment,while in the mosapride group,mosapride citrate was given at the dose of 5 mg once and thrice a day,the therapeutic course of both groups being 7 days. On the 1st,3rd,5th, 7th day after admission,peripheral venous fasting blood in early morning was collected,the activity of diamine oxidase(DAO),expression rates of CD11b+and CD18+in polymorphonuclear neutrophil(PMN),contents of tumour necrosis factor-α(TNF-α)and interleukin-10(IL-10) were detected,and the clinical curative effects were observed. Results Compared to the mosapride citrate treatment group,the total effective rate was significantly higher in the carbachol treatment group on the 7th day after treatment〔70.3%(26/37)vs. 45.5%(15/33),P<0.05〕. The activity of DAO,expression rates of CD11b+and CD18+in PMN,contents of TNF-αand IL-10 in the carbachol treatment group were decreased with the extension of time,and reached valley values on the 7th day,the differences were statistically significant in the comparisons with those in mosapride citrate treatment group at the same time point〔DAO(mg/L):3.21±0.52 vs. 3.93±0.51,CD11b+:(14.89±2.16)% vs.(28.92±1.59)%,CD18+:(53.67±2.44)% vs. (72.46±4.08)%, TNF-α(ng/L):111.44±16.42 vs. 129.73±18.74, IL-10(ng/L):67.71±38.83 vs. 121.45±40.23,all P<0.05〕. At the various time points,the above indexes had no obvious changes in mosapride citrate treatment group. Conclusion Carbachol can ameliorate the ischemic/reperfusion(I/R)injury in patients with intestinal barrier dysfunction after trauma,decrease the release of inflammatory cytokines in vivo,and promote peristalsis of intestinal tract,therefore carbachol has clinical value of protecting intestinal barrier function.
