ABSTRACT

Purpose@#We report outcomes and evaluate patient factors and the impact of surgical evolution on outcomes in consecutive ulcerative colitis patients who had restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) at an Australian institution over 26 years. @*Methods@#Data including clinical characteristics, preoperative medical therapy, and surgical outcomes were collected. We divided eligible patients into 3 period arms (period 1, 1990 to 1999; period 2, 2000 to 2009; period 3, 2010 to 2016). Outcomes of interest were IPAA leak and pouch failure. @*Results@#A total of 212 patients were included. Median follow-up was 50 (interquartile range, 17 to 120) months. Rates of early and late complications were 34.9% and 52.0%, respectively. Early complications included wound infection (9.4%), pelvic sepsis (8.0%), and small bowel obstruction (6.6%) while late complications included small bowel obstruction (18.9%), anal stenosis (16.8%), and pouch fistula (13.3%). Overall, IPAA leak rate was 6.1% and pouch failure rate was 4.8%. Eighty-three patients (42.3%) experienced pouchitis. Over time, we observed an increase in patient exposure to thiopurine (P=0.0025), cyclosporin (P=0.0002), and anti-tumor necrosis factor (P<0.00001) coupled with a shift to laparoscopic technique (P<0.00001), stapled IPAA (P<0.00001), J pouch configuration (P<0.00001), a modified 2-stage procedure (P=0.00012), and a decline in defunctioning ileostomy rate at time of IPAA (P=0.00002). Apart from pouchitis, there was no significant difference in surgical and chronic inflammatory pouch outcomes with time. @*Conclusion@#Despite greater patient exposure to immunomodulatory and biologic therapy before surgery coupled with a significant change in surgical techniques, surgical and chronic inflammatory pouch outcome rates have remained stable.

ABSTRACT

Objective:To evaluate the effects and safety of stress ulcer prophylaxis (SUP) versus no prophylaxis in adult septic patients at risk of gastrointestinal bleeding (GIB).Methods:A retrospective cohort study was conducted, the data was extracted from Electronic Intensive Care Unit-Collaborative Research Database (eICU-CRD). All patients who received proton pump inhibitor (PPI) or H 2 receptor antagonist (H 2RA) or combined/sequential use for SUP within the first 48 hours of intensive care unit (ICU) admission were enrolled in the SUP group, those who did not received any SUP were enrolled in the non-SUP group. The differences of in-hospital mortality, length of ICU stay (LOS), the incidence of GIB and secondary infection complications between the two groups were compared. Propensity score matching (PSM) was conducted to balance the distributions of study variables between the two groups. Further subgroup analysis was performed according to whether SUP was used for more than 3 days. Multivariate Logistic regression analysis was conducted to analyze the factors influencing the outcome of GIB and secondary pneumonia. Results:A total of 11 413 patients were included in the final analysis, with 9 799 patients in SUP group and 1 614 in non-SUP group. A 1∶1 PSM created 1 600 patients in each cohort. ① Baseline characteristics: compared with SUP group, patients in non-SUP group were older [years old: 69.0 (56.0, 80.0) vs. 67.0 (56.0, 78.0)], acute physiology and chronic health evaluation Ⅳ (APACHEⅣ) score and sequential organ failure assessment (SOFA) score were significantly lower [APACHEⅣ score: 65 (50, 73) vs. 72 (58, 87), SOFA score: 5 (4, 7) vs. 7 (5, 9)], higher rates of underlying diseases such as hypertension and diabetes [hypertension: 15.6% (252/1 614) vs. 12.2% (1 196/9 779), diabetes: 4.5% (72/1 614) vs. 3.3% (325/9 779), both P < 0.05], indicating that patients in the SUP group were more severe. ② Comparison of clinical outcome: before PSM, SUP group had significantly higher in-hospital mortality [17.2% (1 688/9 799) vs. 10.9% (176/1 614)], longer LOS [days: 4.4 (2.9, 7.7) vs. 3.1 (2.5, 4.3)], and higher incidence of secondary pneumonia than non-SUP group [11.3% (1 112/9 799) vs. 6.8% (110/1 614)], with significant differences (all P < 0.05). There was no significant difference in the incidence of GIB and Clostridium difficile infection (CDI) between the two groups. After PSM, no significant differences were observed between the two groups with regard to in-hospital mortality, incidence of GIB and CDI. However, the SUP group had longer LOS [days: 3.9 (2.8, 6.6) vs. 3.1 (2.5, 4.3)], and higher incidence of secondary pneumonia [10.9% (174/1 600) vs. 6.8% (108/1 600)] compared with non-SUP group, the differences were statistically significant (all P < 0.05). Subgroup analysis showed that compared with SUP < 3 days group, patients in SUP ≥ 3 days group had higher disease severity score [APACHEⅣ score: 66 (51, 79) vs. 62 (48, 72), SOFA score: 6 (4, 8) vs. 5 (4, 7), both P < 0.05], in addition, patients in SUP≥3 days group had higher in-hospital mortality, incidence of GIB and secondary pneumonia (16.4% vs. 10.7%, 6.1% vs. 1.8%, 19.0% vs. 8.6%, respectively), and longer ICU LOS [days: 6.6 (4.1, 11.8) vs. 3.5 (2.6, 5.3), all P < 0.05]. ③ Multivariate Logistic regression analysis showed that SUP≥3 days group was associated with more GIB than that of non-SUP group [odds ratio ( OR) = 1.84, 95% confidence interval (95% CI) was 1.07-3.08, P = 0.030], and the incidence of GIB was less in SUP < 3 days group than that of non-SUP group ( OR = 0.57, 95% CI was 0.34-0.94, P = 0.020). When compared with non-SUP group, the risk of secondary pneumonia was increased both in SUP≥ 3 days group and SUP < 3 days group ( OR values were 2.95 and 1.34, 95% CI were 2.10-4.13 and 1.01-1.77, P values were < 0.001 and 0.040, respectively). Conclusion:Among critically ill adult patients with sepsis at risk for GIB, SUP showed no effect on reducing in-hospital mortality, the rate of GIB and CDI, but was associated with increased risk of secondary pneumonia and prolonged LOS.

ABSTRACT

Xinjiang is rich in resources of medicinal plants, which are widely used in ethnic medicines because of their remarkable pharmacological activities and safeguard lives and health of people of all ethnic groups in Xinjiang and local health services. The ethnic medicines in Xinjiang are harmonious but different and united in diversity. Besides, they also promote each other and develop together, constituting an inseparable and important part of traditional Chinese medicine in China. Among them, Uygur medicine, Kazak medicine, Kirgiz medicine, Tajik medicine, and Tatar medicine are predominant in regional characteristics, but the development of the ethnic medicine industry in Xinjiang is backward. In recent years, Xinjiang ethnic medicines have been reported to possess significant pharmacological activities, which deserve further development and investigation. However, the development of ethnic medicines in Xinjiang has been restricted severely due to the lack of effective inheritance of practice and experience, weak basic research, insufficient brand awareness, resource destruction, etc. This study analyzed the medicinal value, development status, and prospects of Xinjiang ethnic medicines and summarized the problems in the modernization of ethnic medicines in Xinjiang to provide some scientific references for the follow-up development and clinical application of Xinjiang ethnic medicines, aiming to promote the sustainable development of traditional ethnic medicines of China.

ABSTRACT

Acute pancreatitis (AP) is one of the most common digestive system diseases in clinic. Its pathogenesis is complex and has not yet been fully clarified. It easily progresses to severe AP if the treatment is not provided in time, and the resulting condition is dangerous with high mortality. Intestinal mucosal barrier (IMB) injury is the key link leading to the aggravation of AP. The IMB injury in the late stage of AP promotes the translocation of harmful intestinal bacteria, the entry of bacteria and the produced endotoxins into blood circulation triggers endotoxemia and enterogenous infection,causing multiple organ failure and even death. Western medicine has limitations in the treatment of IMB injury induced by AP. By contrast, Chinese medicine has been proved effective and reliable in repairing the IMB injury induced by AP through oral administration and external application,and has been widely recognized by physicians and patients. AP falls into the categories of "precordial pain due to spleen disorder", "thoracic accumulation", and "pancreas-heat syndrome" in traditional Chinese medicine. The main causes of AP are excessive intake of sweet and greasy food, improper diet, and cholelithiasis, which lead to damp-heat accumulation in the middle energizer, stagnation of spleen and stomach, and obstruction of fu-organ intestine. Therefore, dredging the interior, purging, clearing heat, removing toxin, moving Qi, and activating blood should be emphasized in treatment. According to the related literature both in China and abroad in the past five years, this paper summarized the action mechanisms of Chinese medicine in the treatment of AP-induced IMB injury as follows: It protects the mechanical barrier by improving intestinal microcirculation disorders, relieving intestinal ischemia-reperfusion injury and oxidative stress response, reducing the release of inflammatory mediators and cytokines, and inhibiting the apoptosis of intestinal epithelial cells. It restores the chemical barrier by promoting gastrointestinal functional recovery and shortening enteral nutrition time. It improved the biological barrier by regulating intestinal microecological imbalance. It reinforces the immune barrier by adjusting the level of immune cells. This paper reviewed the characteristics of IMB injury in AP as well as its therapeutic principles and mechanisms with Chinese medicine, aiming to provide a theoretical and scientific basis for the in-depth study and rational application of Chinese medicine for the treatment of IMB injury in AP.

ABSTRACT

Objective:To provide a scientific basis for reducing the rate of invalid ambulance attendance and the establishment of grades dispatch system through a retrospective analysis of the invalid ambulance attendance in prehospital emergency care.Methods:The data of the invalid ambulance attendance was collected in Huazhong University of Science and Technology Union Shenzhen Hospital (the only tertiary hospital of in Nanshan District) from 2014 to 2018, and the reasons of the invalid ambulance attendance, the time period during the invalid ambulance attendance occurred (every 3 hours was divided into one time period), and the reasons of ambulance calling were statistically analyzed.Results:① The invalid ambulance attendance rates showed a fluctuating decrease trend year by year from 2014 to 2018, the rates were 31.22% (2 515/8 055), 26.94% (2 147/7 970), 29.80% (2 398/8 046), 25.69% (1 844/7 177) and 21.89% (1 686/7 703), respectively. The total invalid ambulance attendance rate was 27.19% (10 590/38 951) in the five years. ② The top three reasons for the invalid ambulance attendance were cancelled calls, departure before the ambulance arrived, and going to hospital by themselves, accounting for 36.87%, 25.08%, and 17.03%, respectively. The constituent ratios of the causes of invalid ambulance attendance in each year were different with statistical significance (χ 2 = 217.626, P < 0.001). ③ The top three time period of invalid ambulance attendance occurred at 21:00-23:59, 18:00-20:59 and 09:00-11:59, accounting for 16.86%, 14.95% and 13.54%, respectively. There was no statistical significance in the distribution of time period in each year (χ 2 = 32.571, P = 0.252). ④ The top five reasons for ambulance calling of invalid ambulance attendance were fainting/syncope, trauma, alcoholism, traffic accident injuries, and brawls, accounting for 20.13%, 15.67%, 9.97%, 8.64%, and 6.45%, respectively, and there was statistically significant difference in the distribution of the reason for ambulance calls in each year (χ 2 = 194.213, P < 0.001). Conclusion:The invalid ambulance attendance rate is high in Nanshan District of Shenzhen. Improving the professional level and triage ability of the dispatchers, improving the system construction of prehospital emergency care system and increasing social education are conducive to reduce invalid ambulance attendance rate.

ABSTRACT

Objective@#To evaluate the effect of dexmedetomidine on cell apoptosis during lung ischemia-reperfusion (I/R) injury in a rat model of cardiopulmonary bypass (CPB).@*Methods@#Ninety-six SPF healthy adult male Sprague-Dawley rats, weighing 350-500 g, were divided into 4 groups (n=24 each) using a random number table method: sham operation group(group S), CPB group(group C), CPB plus left lung I/R group (group IR), and CPB plus left lung I/R plus dexmedetomidine group (group D). The chest was only opened, and the rats underwent no CPB in group S. Only the CPB model was established in group C. The model of left lung I/R injury was established based on the CPB model in group IR.In group D, the model of CPB plus left pulmonary I/R injury was established, dexmedetomidine was intravenously infused in a dose of 3 μg/kg through the tail vein, followed by a continuous infusion of 1.5 μg·kg-1·h-1 until the end of surgery.Eight rats were selected in each group before operation (T0), at 10 min after opening the left hilum (T1), and at the end of operation (T2), the left lung tissues were taken for examination of pathological changes (with a light microscope) which were scored and for determination of cell apoptosis, and immunohistochemistry score (IHS) was assessed.The apoptosis index was calculated.@*Results@#Compared with group S, the pathological changes of lung tissues, IHS and apoptosis index were significantly increased at T1, 2 in the other three groups (P<0.05). Compared with group C, the pathological changes of lung tissues, IHS and apoptosis index were significantly increased at T1, 2 in IR and D groups (P<0.05). Compared with group IR, the pathological changes of lung tissues, IHS and apoptosis index were significantly decreased at T2 in group D (P<0.05).@*Conclusion@#The mechanism by which dexmedetomidine reduces lung I/R injury during CPB is related to inhibiting cell apoptosis in rats.

ABSTRACT

Objective To evaluate the effect of dexmedetomidine on oxidative stress and pulmonary function in children with congenital heart disease after cardiopulmonary bypass. Methods From June 2016 to June 2018, fifty-five children who underwent ventricular septal or atrial defect repair under cardiopulmonary bypass in the First Affiliated Hospital of Zunyi Medical University were recruited and randomly divided into two groups: control group (group C) and dexmedetomidine group (group D). After tracheal intubation, patients of group D were received dexmedetomidine 0.5 ug/kg/h by intravenous pump until the end of operation. Patients of group C were received 0.9% physiological saline with the same volume. Heart rate, mean arterial pressure, oxygen saturation, bypass time, and computation of respiratory index (RI) and oxygenation index (OI) based on blood gas analysis, measured SOD, MDA and GSH in plasma, recording the time from the end of operation to the extubation of tracheal tube, the duration of stay in extracardiac ICU after operation, and pulmonary complications were followed up before infusion of dexmedetomidine (T0), sternal sawing (T1), CPB stopping (T2), and 24 hours after operation (T3). Results The changes of heart rate and mean arterial pressure in the two groups were within the normal range. There was no significant difference in plasma SOD, MDA and GSH between the two groups (P>0.05). There was no difference in OI and RI at T0 and T1 time points (P>0.05). Compared with group C, OI was increased and RI was decreased in group D at T2 and T3 time points (P< 0.05). Compared with group C, group D had shorter ICU support time and extubation time, and fewer pulmonary complications after operation (P<0.05). Conclusion The treatment of 0.5 μg/kg/h dexmedetomidine can improve the respiratory function, reduce the pulmonary complications, and is conducive to the rehabilitation of children after CPB. But, this concentration cannot alleviate the oxidative stress reaction of children with CPB.

ABSTRACT

Objective To evaluate the chemopreventive effects of 8-allyl garcinol on oral squamous cell carcinoma(OSCC).Methods OSCC cell line CAL27 were cultured and treated with different concentrations of garcinol or 8-allyl garcinol. Their effects on the biological behaviors of OSCC cell line CAL27 were measured by MTT assay,clony formation assay,scratch migration assay,and flow cytometry with Annexin V-FITC/PI staining assay. We established DMBA-induced hamster cheek pouch models of dysplasia. While the negative control group was not treated,the positive group was treated with 0.5% DMBA solution tropically to the left cheek pouch three times per week for three consecutive weeks. The other four groups received 0.5 mmol/L or 1.0 mmol/L garcinol or 8-allyl garcinol respectively three times within the following two weeks after DMBA treatment. Hamsters were sacrificed at the fifth week to obtain tissue samples of the left cheek pouch. The samples were examined by histopathology and BrdU immunohistochemisty.Results MTT assay showed that both garcinol and 8-allyl garcinol inhibited the proliferation of CAL27 cells in a concentration-and time-dependent manner. The half maximal inhibitory concentration(IC)of 8-allyl garcinol[(13.13±2.55)μmol/L] was significantly lower than garcinol[(32.20±3.24)μmol/L;t=8.008,P=0.001]. Comparing the two grougs of medicine in the same concentration,the inhibiting proliferation effects 8-allyl garcinol had significantly stronger effect in inhibiting proliferation than garcinol when the same dose was applied,and the difference was largest at the concentrations of 10(24 h:t=8.012,P=0.001;48 h:t=5.939,P=0.001;72 h:t=12.551,P=0.001)and 20 μmol/L(24 h:t=8.887,P=0.001;48 h:t=9.324,P=0.002;72 h:t=5.361,P=0.002). The clone formation assay showed the clone formation rates after the treatment with 20 μmol/L garcinol and 20 μmol/L 8-allyl garcinol were(44.1±0.4)% and(23.6±0.6)%,respectively,which were significantly lower than those after treatment with 10 μmol/L garcinol[(55.6±2.8)%;t=6.894,P=0.019] and 10 μmol/L 8-allyl garcinol[(31.0±0.6)%;t=15.556,P=0.001]. The inhibiting effects of 8-allyl garcinol at the concentrations of 10 μmol/L(t=14.682,P=0.003)and 20 μmol/L(t=51.514,P=0.001)were significantly stronger than garcinol.Scratch test showed the relative cell migration rates after treatment with 10 and 20 μmol/L garcinol for 12 hours were(16.00±4.55)%(t=3.139,P=0.026)and(3.00±3.16)%(t=6.608,P=0.001),respectively,which were lower than negative control [(30.33±7.64)%]. The relative cell migration rates after treatment with 10 and 20 μmol/L 8-allyl garcinol for 12 hours were(16.25±3.86)%(t=3.245,P=0.023)and(6.00±2.65)%(t=5.214,P=0.006),respectively,which were also lower than negative control[(30.33±7.64)%]. In addition,the relative cell migration rates after treatment with 10 and 20 μmol/L garcinol for 24 hours were(23.75±4.57)%(t=4.718,P=0.005)and(5.75±1.50)%(t=10.432,P=0.001),respectively,which were lower than negative control[(45.33±7.64)%]. The relative cell migration rates after treatment with 10 and 20 μmol/L 8-allyl garcinol for 24 hours were(23.50±2.38)%(t=5.529,P=0.003)and(11.67±2.31)%(t=7.308,P=0.002),respectively,which were also lower than negative control[(45.33±7.64)%]. Furthermore,the relative cell migration rate after treatment with 20 μmol/L garcinol for 24 hours was significantly lower than after treatment with 8-allyl garcinol(t=4.151,P=0.009). The apoptosis experiments showed that the early apoptosis rate of CAL27 cells was(5.00±0.10)% after treatment with 10 μmol/L garcinol,which was significantly higher than negative control[(1.57±0.21)%;F=70.950,P=0.001]. The early and late apoptosis rates of CAL27 cells were(5.90±0.78)%(t=39.384,P=0.001)and(9.73±1.67)%(t=10.101,P=0.001),respectively,after treatment with 20 μmol/L garcinol,which were also significantly higher than negative control. The early apoptosis rate of CAL27 cells was(4.63±1.16)% after treatment with 8-allyl garcinol,which was significantly higher than negative control(t=4.511,P=0.041). The effects of 8-allyl garcinol in promoting cell apoptosis were weaker than garcinol(10 μmol/L:t=5.982,P=0.004;20 μmol/L:t=8.578,P=0.001). The histopathological test also showed that the hyperplastic areas of oral mucosal epithelium in hamsters after treatment with 0.5 mmol/L garcinol(t=2.546,P=0.031),0.5 mmol/L 8-allyl garcinol(t=3.485,P=0.008),1.0 mmol/L garcinol(t=4.556,P=0.001),and 1.0 mmol/L 8-allyl garcinol(t=5.393,P=0.001)were significantly smaller than positive control. The dysplasia areas of oral mucosal epithelium in hamsters after treatment with 0.5 mmol/L 8-allyl garcinol(t=2.130,P=0.046),1.0 mmol/L garcinol(t=3.434,P=0.010),and 1.0 mmol/L 8-allyl garcinol(t=4.518,P=0.004)were also smaller than positive control;1.0 mmol/L garcinol group(t=2.793,P=0.023)and 1.0 mmol/L 8-allyl garcinol group(t=4.997,P=0.001)were smaller than 0.5 mmol/L garcinol treatment group. Immunohistochemical staining of BrdU showed that the BrdU-labeled indicators were significantly lower in negative control group(t=7.563,P=0.001),0.5 mmol/L garcinol(t=2.862,P=0.029),0.5 mmol/L 8-allyl garcinol(t=4.693,P=0.002),1.0 mmol/L garcinol(t=5.071,P=0.002),and 1.0 mmol/L 8-allyl garcinol(t=5.133,P=0.001)when compared with the positive control. The BrdU-labeled indicators in 0.5 mmol/L 8-allyl garcinol(t=3.724,P=0.007),1.0 mmol/L garcinol(t=7.000,P=0.001),and 1.0 mmol/L 8-allyl garcinol(t=4.413,P=0.003)were also significantly lower than in 0.5 mmol/L garcinol group.Conclusions 8-allyl garcinol could inhibit the proliferation and migration of OSCC cell line CAL27 and promotes apoptosis. It also has prominent inhibitory effects on DMBA-induced hamster cheek pouch dysplasia. However,the specific effects are slightly different from garcinol.

ABSTRACT

In this paper,the effects of active fractions of Ferula ferulaeoides on the growth and apoptosis of human gastric cancer cell MGC-803 transplantation tumor were systematically studied. The subcutaneous ectopic transplantation tumor model was established in human gastric cancer MGC-803 nude mice by cell suspension implantation method. The anti-tumor rate and organ index were used to evaluate the anti-tumor effect of the active fractions of F. ferulaeoides on the tumor-bearing nude mice. HE staining,TUNEL staining,RT-PCR,Western-blot and ELISA were used for pathological examination,apoptosis observation,and detection of apoptosis-related genes,proteins and cytokines expression. The results showed that as compared with the model group,the low,medium and high doses of the active fraction of F. ferulaeoides had inhibitory effects on xenografts in nude mice,respectively,in a dose-dependent manner; the apoptotic ratio was increased with the increase of drug concentration. As compared with the model group,F. ferulaeoides could down-regulate the expression of survivin mRNA in nude mice,and the protein expression levels of Bax,Bcl-2,caspase-3 and caspase-9 in tumor tissues of nude mice could be increased to different degrees in F. ferulaeoides groups. The contents of IL-10 and TGF-β1 in plasma of nude mice were decreased in high dose group of F. ferulaeoides active fractions. The results indicated that F. ferulaeoides can significantly inhibit the growth of human gastric cancer MGC-803 subcutaneously transplanted tumor,and its mechanism may be related with down-regulating the expression of survivin mRNA,and up-regulating the expression of apoptosis-related proteins Bax,caspase-3 and caspase-9.

ABSTRACT

OBJECTIVE@#To compare the clinical effect of acupuncture at "three points of iliolumbar" combined with celecoxib and celecoxib alone in the treatment of iliopsoas muscle strain.@*METHODS@#A total of 60 patients with iliopsoas muscle strain were randomly divided into an observation group and a control group, 30 patients in each group. Celecoxib was given orally to both groups, 200 mg once a day for 3 days. On the basis of the above drugs, acupuncture was applied at (Extra), Wushu (GB 27), (Extra) in the observation group, once a day for 3 days. The Japanese Orthopaedic Association (JOA) score and visual analogue scale (VAS) score were observed and compared before and after treatment, and the content of 5-hydroxytryptamine (5-HT) in serum was detected by enzyme-linked immunosorbent assay (ELISA) before and after treatment in the two groups.@*RESULTS@#After treatment, the JOA scores in the two groups were increased (both <0.05), and the VAS scores and 5-HT contents were decreased (all <0.05). The increase of JOA score in the observation group was greater than that in the control group (<0.05), and the decrease of VAS score and 5-HT content in the observation group was greater than that in the control group (both <0.05).@*CONCLUSION@#Acupuncture at "three points of ilioumbar" combined with celecoxib in the treatment of iliopsoas muscle strain can improve lumbar function, relieve pain and reduce 5-HT content in serum, which is better than celecoxib alone.

ABSTRACT

Objective To evaluate the effect of dexmedetomidine on cell apoptosis during lung is-chemia-reperfusion(I/R)injury in a rat model of cardiopulmonary bypass(CPB).Methods Ninety-six SPF healthy adult male Sprague-Dawley rats,weighing 350-500 g,were divided into 4 groups(n=24 each)using a random number table method: sham operation group(group S),CPB group(group C),CPB plus left lung I/R group(group IR),and CPB plus left lung I/R plus dexmedetomidine group(group D).The chest was only opened,and the rats underwent no CPB in group S.Only the CPB model was es-tablished in group C.The model of left lung I/R injury was established based on the CPB model in group IR.In group D,the model of CPB plus left pulmonary I/R injury was established,dexmedetomidine was intrave-nously infused in a dose of 3 μg/kg through the tail vein,followed by a continuous infusion of 1.5 μg?kg-1?h-1 until the end of surgery.Eight rats were selected in each group before operation(T0),at 10 min after opening the left hilum(T1),and at the end of operation(T2),the left lung tissues were taken for examination of pathological changes(with a light microscope)which were scored and for determination of cell apoptosis,and immunohistochemistry score(IHS)was assessed.The apoptosis index was calculated.Results Compared with group S,the pathological changes of lung tissues,IHS and apoptosis index were significantly increased at T1,2 in the other three groups(P<0.05).Compared with group C,the pathologi-cal changes of lung tissues,IHS and apoptosis index were significantly increased at T1,2 in IR and D groups(P<0.05).Compared with group IR,the pathological changes of lung tissues,IHS and apoptosis index were significantly decreased at T2 in group D(P<0.05).Conclusion The mechanism by which dexme-detomidine reduces lung I/R injury during CPB is related to inhibiting cell apoptosis in rats.

ABSTRACT

Objective To evaluate the role of PI3K∕Akt signaling pathway in dexmedetomidine-in-duced reduction of lung ischemia-reperfusion ( I∕R ) injury in rats undergoing cardiopulmonary bypass (CPB). Methods Twenty-four healthy adult male Sprague-Dawley rats, weighing 350-450 g, were di-vided into 3 groups (n=8 each) using a random number table method: group I∕R, dexmedetomidine group ( group D) and dexmedetomidine plus wortmannin group (group D+W). Rats were anesthetized with pento-barbital sodium. Lung I∕R was induced by clamping the left hilum of lung for 60 min starting from 10 min of CPB, followed by 120-min reperfusion. Dexmedetomidine was injected via the tail vein in a dose of 3 μg∕kg at 10 min before clamping the left hilum of lung, followed by a continuous infusion of 1. 5 μg·kg-1·h-1 until the end of CPB in group D. Dexmedetomidine was injected via the tail vein in a dose of 3 μg∕kg at 10 min before clamping the left hilum of lung, followed by a continuous infusion of 1. 5 μg·kg-1·h-1until the end of CPB, and wortmannin was simultaneously injected via the tail vein in a dose of 15 μg∕kg, fol-lowed by a continuous infusion of 2. 0 μg·kg-1·min-1until the end of CPB in group D+W. Arterial blood samples were collected immediately before CPB ( T1), immediately after opening the left hilum of lung (T2) and at 1. 5 h after the end of CPB (T3), and oxygenation index (OI) and respiratory index (RI) were calculated. The rats were sacrificed at T3, and the left lung was removed for examination of the patho-logical changes which were scored and for determination of apoptosis rate ( by flow cytometry) and Akt, Bad, activated caspase-3, phosphorylated Akt ( p-Akt) and phosphorylated Bad ( p-Bad) in lung tissues ( by Western blot). Results Compared with the baseline at T1, OI was significantly decreased and RI was increased at T2and T3in the three groups (P<0. 05). OI was significantly decreased and RI was increased at T3than at T2in the three groups ( P<0. 05). Compared with group I∕R, OI was significantly increased and RI was decreased at T3, the pathological damage score and apoptosis rate were decreased, ratios of p-Akt∕Akt and p-Bad∕Bad were increased, and the expression of activated caspase-3 was down-regulated in group D, and OI was significantly decreased and RI was increased at T2in group D+W ( P<0. 05). Com-pared with group D, OI was significantly decreased and RI was increased at T3, the pathological damage score and apoptosis rate were increased, ratios of p-Akt∕Akt and p-Bad∕Bad were decreased, and the ex-pression of activated caspase-3 was up-regulated in group D+W ( P<0. 05). Conclusion Dexmedetomi-dine can reduce dexmedetomidine-induced reduction of lung I∕R injury through activating PI3K∕Akt signa-ling pathway and inhibiting cell apoptosis in rats undergoing CPB.
