ABSTRACT

Objective:To investigate the efficacy of liposomal doxorubicin intensive preconditioning regimen and allogeneic hematopoietic stem cell transplantation (allo-HSCT) in treatment of leukemia.Methods:The data of 20 patients with intensive preconditioning regimen allo-HSCT who were admitted to Shenzhen Second People's Hospital from January 2016 to June 2017 were retrospectively analyzed. The transplantation effect, occurrence of complications and prognosis of patients were analyzed.Results:The median time of granulocyte engraftment was 17 d (13-23 d); the median time of platelet engraftment was 22.5 d (minimum 13 d, maximum >90 d). The acute graft-versus-host disease (GVHD) and chronic GVHD occurred in 2 cases and 1 case, respectively. Eight cases occurred hemorrhagic cystitis, 15 cases occurred Epstein-Barr viremia, 8 cases occurred cytomegaloviremia, 1 case occurred sepsis, 1 case occurred acute liver injury, and 2 cases occurred fungal pneumonia. The median follow-up time was 31.7 months (0.8-53.8 months). One patient died of intracranial infection on the 25th day after transplantation; 3 patients relapsed during the follow-up period, and 2 of them died; the other 16 patients carried 100% donor genes during the follow-up period.Conclusions:The liposomal doxorubicin intensive preconditioning regimen and allo-HSCT have a good effect on leukemia. Increasing the intensity of pretreatment does not increase the treatment-related adverse reactions. The incidence rates of Epstein-Barr viremia and cytomegaloviremia are high, but they are improved after active treatment.

ABSTRACT

Objective:To compare the growth speed of pulmonary artery and left ventricle after the repair of tetralogy of Fallot(TOF) with valve-sparing and transannular patch.Methods:The clinical data of children with tetralogy of Fallot admitted to our hospital from January 2015 to October 2020 were reviewed. According to the way of relieving right ventricular outflow tract stenosis, they were divided into two groups: valve-sparing and transannular patch. Independent sample t test or non- parametric test was used to compare the pulmonary artery and left ventricular growth indexes before operation and at the last follow-up between the two groups. The paired t test was used to compare preoperative and postoperative indexes. Results:A total of 104 children with tetralogy of Fallot, including 58 males and 46 females, had surgery at a median age and weight of 6.7(4.1, 10.3) months and 7.0(5.8, 8.4) kg, respectively. The preoperative Nakata index, McGoon ratio, pulmonary artery Z-score, left ventricular end diastolic volume(LVEDV) index and Z-score in valve-sparing were higher than those in transannular patch( P=0.001, 0.000, 0.003, 0.000, 0.000). At the last follow-up, the Z-scores of pulmonary arteries in both groups were greater than those before operation( P=0.016, 0.000), the LVEDV Z-score in transannular patch was greater than that before surgery( P=0.000), while the LVEDV Z-score of valve-sparing was not significantly different from that before operation( P=0.581), there was no significant difference in pulmonary artery Z-score and LVEDV Z-score between two groups( P=0.468, 0.884). The difference between the last follow-up and preoperative of pulmonary artery Z-score and LVEDV Z-score in valve-sparing was smaller than that in transannular patch( P=0.000, 0.000). Conclusion:Compared with valve-sparing, the pulmonary artery and left ventricle grow faster in transannular patch during the early stage after TOF repair.

ABSTRACT

Objective:To investigate the clinical efficacy of laparoscopic-assisted inters-phincteric resection (ISR) with different surgical approaches for low rectal cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 90 patients with low rectal cancer who were admitted to the Second Affiliated Hospital of Fujian Medical University from January 2016 to December 2020 were collected. There were 58 males and 32 females, aged (60±9)years. Of 90 patients, 60 cases underwent laparoscopic assisted ISR with transpelvic approach, 30 cases underwent laparoscopic assisted ISR with transabdominal and transanal mixed approach. Observation indicators: (1) clinicopathological characteristics of patients with transpelvic approach and mixed approach; (2) intraoperative and postoperative conditions of patients with transpelvic approach and mixed approach; (3) postoperative complications of patients with transpelvic approach and mixed approach; (4) follow-up. Follow-up was conducted by telephone interview and outpatient examination once every 3 months within postoperative 3 years, once every six months in the postoperative 3 to 5 years and once a year after postoperative 5 years to detect tumor recurrence and metastasis, and survival of patients.Follow-up was up to March 2021 or patient death. Measurement data with normal distribution were represented as Mean± SD, and the t test was used for comparison between groups. Measurement data with skewed distribution were expressed as M(range), and comparison between groups was conducted using the non-parametric Mann-Whitney U test. Count data were expressed as absolute numbers or percentages, and comparison between groups was performed using the chi-square test or Fisher exact probability. Comparison of ordinal data was analyzed by the non-parametric rank sum test. Kaplan-Meier method was used to draw survival curves and calculate survival rates, and survival analysis was performed by the Log-Rank test. Results:(1) Clinicopathological characteristics of patients with transpelvic approach and mixed approach. The sex (males, females), distance from the distal margin of tumor to anal margin were 34, 26, (4.5±0.5)cm for patients with transpelvic approach, versus 24, 6, (3.5±0.5)cm for patients with mixed approach, respectively, showing significant differences between them ( χ2=4.75, t=8.35, P<0.05). (2) Intraoperative and postoperative conditions of patients with transpelvic approach and mixed approach. The operation time, volume of intraoperative blood loss, distance from the postoperative anastomosis to anal margin were (187±9)minutes, 50(range, 20?200)mL, (3.4±0.7)cm for patients with transpelvic approach, versus (256±12)minuets, 100(range, 20?200)mL, (2.6±0.7)cm for patients with mixed approach, showing significant differences between them ( t=?26.99, Z=?2.48, t=4.67, P<0.05). None of the 90 patients had a positive distal margin. The stoma reversal rates of patients with transpelvic and mixed approach were 93.3%(56/60) and 90.0%(27/30), respectively. Of the 60 patients with transpelvic approach, 3 cases had no stoma reversal due to anastomotic complications, and 1 case was not yet to the reversal time. Of the 30 patients with mixed approach, 2 cases had no stoma reversal due to anastomotic complications, and 1 case was not yet to the reversal time. The 1-, 3-month Wexner scores after stoma reversal were 15(range, 12?17), 12(range, 10?14) for patients with transpelvic approach, versus 16(range, 14?18), 14(range, 12?16) for patients with mixed approach, showing significant differences between them ( Z=?4.97, ?5.49, P<0.05). The 6-month Wexner score after stoma reversal was 10(range, 9?12) for patients with transpelvic approach, versus 11(range, 8?12) for patients with mixed approach, showing no significant difference between them ( Z=?1.59, P>0.05). (3) Postoperative complications of patients with transpelvic approach and mixed approach. The complications occurred to 16 patients with transpelvic approach and 9 patients with mixed approach, respectively, showing no significant difference between them ( χ2=0.11, P>0.05). Cases with postoperative anastomotic fistula, cases with anastomotic bleeding, cases with anastomotic stenosis, cases with intestinal obstruction, cases with incision infection, cases with urinary retention, cases with pelvic infection, cases with pulmonary infection, cases with incisional hernia, cases with chylous fistula, cases with abdominal and pelvic abscess were 5, 2, 1, 7, 0, 1, 5, 3, 1, 1, 1 for patients with transpelvic approach, versus 6, 3, 2, 2, 2, 1, 2, 3, 1, 1, 1 for patients with mixed approach, showing no significant difference between them ( P>0.05). The same patient could have multiple postoperative complications. (4) Follow-up. All the 90 patients were followed up for 27(range, 6?62)months. The follow-up time of 60 patients with transpelvic approach was 27(range, 8?62)months. The follow-up time of 30 patients with mixed approach was 28(range, 6?53)months. Of the 60 patients with transpelvic approach, 3 cases had local recurrence, 4 cases had liver metastasis, 3 cases had lung metastasis, and all of them survived with tumor. Of the 30 patients with mixed approach, 1 case had local recurrence, 2 cases had liver metastasis, 1 case had lung metastasis, and all of them survived with tumor. There was no death. The 3-year disease-free survival rates of patients with transpelvic approach and mixed approach were 84.7% and 87.9%, respectively, showing no significant difference between them ( χ2=0.39, P>0.05). Conclusions:Lapa-roscopic assisted ISR via transpelvic approach or mixed approach for low rectal cancer are safe and feasible. Compared with transanal mixed approach, the transpelvic approach of laparoscopic-assisted ISR has shorter operation time, less volume of intraoperative blood loss and longer distance from the postoperative anastomosis to anal margin.

ABSTRACT

@#Objective    To summarize the experience and lessons of right ventricular decompression in children with pulmonary atresia and intact ventricular septum (PA/IVS) and to reflect on the strategies of right ventricular decompression. Methods    The clinical data of 12 children with PA/IVS who underwent right ventricular decompression in our hospital from March 2015 to December 2019 were reviewed retrospectively. There were 10 males and 2 females with a median age at the time of surgery was 5 d (range, 1-627 d). Correlation analysis between the pulmonary valve transvalvular pressure gradient and changes in Z score of tricuspid valves after decompression was performed. Results    One patient died of refractory hypoxemia due to circulatory shunt postoperatively and family members gave up treatment. There were 2 (16.67%) patients received postoperative intervention. The pulmonary transvalvular gradient after decompression was 31.95±21.75 mm Hg. Mild pulmonary regurgitation was found in 7 patients, moderate in 2 patients, and massive in 1 patient. The median time of mechanical ventilation was 30.50 h (range, 6.00-270.50 h), and the average duration of ICU stay was 164.06±87.74 h. The average postoperative follow-up time was 354.82±331.37 d. At the last follow-up, the average Z score of tricuspid valves was 1.32±0.71, the median pressure gradient between right ventricle and main pulmonary artery was 41.75 mm Hg (range, 21-146 mm Hg) and the average percutaneous oxygen saturation was 92.78%±3.73%. Two children underwent percutaneous balloon pulmonary valvoplasty at 6 and 10 months after surgery, respectively, with the rate of reintervention-free of 81.8%. There was no significant correlation between pulmonary transvalvular gradients after decompression and changes in Z score of tricuspid valves (r=–0.506, P=0.201). Conclusion    For children with PA/IVS, the simple pursuit of adequate decompression during right ventricular decompression may lead to  severe pulmonary dysfunction, increase the risk of ineffective circular shunt, and induce refractory hypoxemia. The staged decompression can ensure the safety and effectiveness for initial surgery and reduce the risk of postoperative death.

ABSTRACT

Objective:To review and analyze the clinical experience of children with aortic valve stenosis and/or insufficiency treated with autologous pulmonary valve for aortic valve replacement procedure(Ross operation) with ePTFE artificial valve for right ventricular outflow tract reconstruction.Methods:From 2015 to 2020, 8 cases of aortic stenosis and/or aortic insufficiency treated by Ross operation in our center were collected, with an age of 0.5-13.2 years old. 4 cases of aortic stenosis were diagnosed preoperatively, 3 cases of aortic stenosis with aortic insufficiency, and 1 case of infective endocarditis involving the aortic valve. The operation was carried out in three steps: Harvest autologous pulmonary valve; the diseased aortic valve was resected and autologous pulmonary valve was transplanted to the aorta by aortic root transplantation; the right ventricular outflow tract was reconstructed by a handmade ePTFE artificial flap blood vessel.Results:In 6 cases, the right ventricular outflow tract was reconstructed by hand-sewn ePTFE trileaflets, and artificial univalve in 2 cases, no death occurred during operation; all patients were cured and discharged. The patients were followed up for 1 to 36 months, with mean of(12.63±12.19) months. There was no long-term death or valvular complications. During follow-up echocardiography indicated 1 case of moderate aortic regurgitation, 1 case of mild-moderate regurgitation, and moderate regurgitation was found in 2 patients with artificial single pulmonary valve. For the remaining patients, they were mild aortic regurgitation, and a trivial or mild pulmonary artery regurgitation with hand-sewn three-leaflets ePTFE artificial vessel; All patients were followed up at the last time with a peak pressure of(6.63±3.46) mmHg(1 mmHg=0.133 kPa) across the aortic valve. The left ventricular outflow tract and aortic annulus shrank slightly after surgery(the diameter of one patient with Ross-Konno operation increased), but the annulus diameter increased with age. There was no need for further intervention.Conclusion:The Ross operation is safe for the treatment of aortic valve disease, it has good hemodynamic effect, and the autologous pulmonary artery has growth potential, especially suitable for children and young patients. Hand-sewn ePTFE with trileaflet vessels for reconstruction of right ventricular outflow tract performs well in anti-regurgitation function in the short term or may be used as a replacement material for the homograft/heterograft vessel, but longer follow-up and more cases are needed.

ABSTRACT

Objective:To evaluate the effect of dexmedetomidine on pyroptosis in rats with endotoxin-induced acute lung injury (ALI).Methods:Sixty SPF male Sprague-Dawley rats, aged 6 weeks, weighing 200-220 g, were divided into 5 groups ( n=10 each) by a random number table method: control group (group C), ALI group and different doses of dexmedetomidine groups (D 1-3 groups). In ALI group and D 1-3 groups, LPS 5 mg/kg was intraperitoneally injected to establish endotoxin-induced ALI model.Immediately after establishing the model, dexmedetomidine 12.5, 25.0 and 50.0 μg/kg were intraperitoneally injected in D 1-3 groups, and the equal volume of normal saline was intraperitoneally injected in group C, once a day for 14 consecutive days.After the end of administration, the rats were sacrificed, the left bronchus was lavaged, and the left bronchoalveolar lavage fluid (BALF) was collected for determination of the concentrations of interleukin-1beta (IL-1β), IL-6 and tumor necrosis factor-alpha (TNF-α) (by enzyme-linked immunosorbent assay), and the lung tissue was taken for determination of the wet/dry weight ratio (W/D ratio) and expression of cleaved-caspase-1, N-terminal of the spliceosome (GSDMD-N), IL-18 and IL-1β (by Western blot) and for microscopic examination of the pathological changes (with a light microscope). Results:Compared with group C, the W/D ratio of lung tissues was significantly increased, the concentrations of IL-1β, IL-6 and TNF-α in BALF were increased, the expression of cleaved-caspase-1, GSDMD-N, IL-1β and IL-18 in lung tissues was up-regulated ( P<0.05), and the pathological damage was aggravated in ALI group and D 1-3 groups.Compared with group ALI, the W/D ratio of lung tissues was significantly decreased, and the concentrations of IL-1β, IL-6 and TNF-α in BALF were decreased, the expression of cleaved-caspase-1, GSDMD-N, IL-1β and IL-18 in lung tissues was down-regulated in a dose-dependent manner ( P<0.05), and the pathological damage was significantly reduced in D 1-3 groups. Conclusion:The mechanism by which dexmedetomidine attenuates endotoxin-induced ALI may be related to inhibition of pyroptosis and reduction of inflammatory responses in rats.

ABSTRACT

Objective:To investigate the timing of primary repair for tetralogy of Fallot based on pulmonary valve-sparing.Methods:A retrospective analysis of the perioperative data of children undergoing primary repair for tetralogy of Fallot in our hospital between June 2015 and May 2019 was performed. To determinate cutoff value of pulmonary valve-sparing by using receiver operating characteristic curve( ROC curve); the children were divided into two groups according to the age of cutoff value. The duration of postoperative mechanical ventilation, the length of hospital and ICU stay, emergency surgery rate, hospital mortality, 31 day readmission rate, valve-sparing rate and fast-track rate and other indicators were compared between the two groups. Results:A total of 105 children were enrolled according to the inclusion criteria, including 67 males and 38 females, with a body mass of 4.21 kg to 21.5 kg, the median body mass was 7.9 kg, and age 1.3 months to 99.1 months, the median age was 8.8 months. Cutoff value of age for pulmonary valve-sparing was between 5.5 months and 5.6 months(sensitivity 0.90, specificity 0.58, 95% CI: 0.588-0.792). Based on the age of 6 months, the children with tetralogy of Fallot were divided into two groups.There were no significant differences in duration of postoperative mechanical ventilation, length of ICU stay, emergency surgery rate, hospital mortality, 31 day readmission rate and fast-track rate in <6 months group compared with those in ≥6 months group( P>0.05). The rate of valve-sparing in <6 months group was higher than that in ≥6 months group(65.52% vs. 30.26%)( P<0.01), and the length of hospital stay was lower than that in ≥6 months group(11 days vs. 15 days)( P<0.01). The median follow-up was 14.5 months(0.3-54.9 months), and there was no reoperation intervention at the last follow-up. There were no significant difference in the follow-up period, pulmonary regurgitation and residual obstruction between the two groups( P>0.05). Conclusion:Therapeutic effect of elective early primary repair for tetralogy of Fallot in infants is not only satisfactory, but also improve the rate of pulmonary valve-sparing during operation. It is recommended that the age of elective primary repair for tetralogy of Fallot should be advanced to less than 6 months.

ABSTRACT

Objective:To intestigate the clinical efficacy between modified Overlap anastomosis and traditional auxiliary incision anastomosis in laparoscopic total gastrectomy.Methods:The retrospective cohort study was conducted. The clinicopathological data of 115 patients with gastric cancer who were admitted to the Second Affiliated Hospital of Fujian Medical University from January 2016 to December 2018 were collected. There were 62 males and 53 females, aged from 27 to 83 years, with a median age of 62 years. Of 115 patients, 51 patients undergoing totally laparoscopic total gastrectomy with modified Overlap anastomosis using linear stapler were divided into modified Overlap group and 64 patients undergoing laparoscopic assisted total gastrectomy with traditional auxiliary incision anastomosis using circular stapler were divided into traditional assisted group. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) anastomotic complications; (4) follow-up. Follow-up using outpatient examination or telephone interview was conducted to detected tumor recurrence and survival of patients up to December 2019. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Count data were represented as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Comparison of ranked data was analyzed using the rank sum test. Results:(1) Surgical situations: the operation time, time of esophagojejunostomy, volume of intraoperative blood loss, the number of lymph node dissected, length of proximal incisional margin and length of auxiliary incision of the modified Overlap group were (234.0±11.0)minutes, (29.4±2.1)minutes, (53±14)mL, 42±13, (2.0±0.3)cm and (5.1±0.4)cm, respectively. The above indicators of the traditional assisted group were (231.0±11.0)minutes, (29.2±2.2)minutes, (50±13)mL, 40±10, (2.2±0.4)cm and (8.2±0.4)cm, respectively. There was significant difference in the length of auxiliary incision between the two groups ( t=-43.098, P<0.05), and there was no significant difference in the operation time, time of esophagojejunostomy, volume of intraoperative blood loss, the number of lymph node dissected, length of proximal incisional margin between the two groups ( t=1.168, 0.460, 0.990, 1.127, -1.926, P>0.05). (2) Postoperative situations: cases with mild, moderate, severe pain (postoperative pain degree), time to first flatus, time to initial fluid diet intake, duration of postoperative hospital stay of the modified Overlap group were 40, 9, 2, (2.9±1.0)days, (4.8±2.2)days, (11.7±2.8)days, respectively. The above indicators of the traditional assisted group were 31, 27, 6, (3.9±1.4)days, (6.5±2.5)days, (13.0±3.1)days, respectively. There were significant differences in the above indicators between the two groups ( Z=-3.217, t= -4.344, -3.888, -2.261, P<0.05). (3) Anastomotic complications: cases with anastomotic leakage, cases with anastomotic bleeding, cases with anastomotic stenosis of the modified Overlap group were 1, 1, 0, respectively. The above indicators of the traditional assisted group were all 1. There was no significant difference in the above indicators between the two groups ( P>0.05). Cases with anastomotic leakage were cured after the treatment of enteral nutritional support through nasogastric catheterization, which were confirmed by gastroenterography. Cases with anastomotic bleeding were improved by active hemostatic therapy. Cases with anastomotic stenosis were improved after the symptomatic treatment of anti-inflammatory and anti-swelling. (4) Follow-up: 109 of the 115 patients were followed up. Forty-eight of 51 patients in the modified Overlap group were followed up for 15.0-45.0 months, with a median follow-up time of 33.5 months. Sixty-one of 64 patients in the traditional assisted group were followed up for 16.0-46.0 months, with a median follow-up time of 27.0 months. There was no tumor recurrence in the modified Overlap group. One patient in the traditional assisted group had tumor recurrence with liver metastasis and survived with tumor. There was no significant difference in tumor recurrence rate between the two groups ( P>0.05). There was no patient died during the follow-up. Conclusion:Compared with traditional auxiliary incision anastomosis, patients undergoing total laparoscopic total gastrectomy with modified Overlap anastomosis have small incision, good postoperative recovery.

ABSTRACT

PURPOSE: The significance of neuroendocrine differentiation (NED) in gastric carcinoma (GC) is controversial, leading to ambiguous concepts in traditional classifications. This study aimed to determine the prognostic threshold of meaningful NED in GC and clarify its unclear features in existing classifications. MATERIALS AND METHODS: Immunohistochemical staining for synaptophysin, chromogranin A, and neural cell adhesion molecule was performed for 945 GC specimens. Survival analysis was performed using the log-rank test and univariate/multivariate models with percentages of NED (PNED) and demographic and clinicopathological parameters. RESULTS: In total, 275 (29.1%) cases were immunoreactive to at least 1 neuroendocrine (NE) marker. GC-NED was more common in the upper third of the stomach. PNED, and Borrmann's classification and tumor, lymph node, metastasis stages were independent prognostic factors. The cutoff PNED was 10%, beyond which patients had significantly worse outcomes, although the risk did not increase with higher PNED. Tumors with ≥10% NED tended to manifest as Borrmann type III lesion with mixed/diffuse morphology and poorer histological differentiation; the NE components in this population mainly grew in insulae/nests, which differed from the predominant growth pattern (glandular/acinar) in GC with <10% NED. CONCLUSIONS: GC with ≥10% NED should be classified as a distinct subtype because of its worse prognosis, and more attention should be paid to the necessity of additional therapeutics for NE components.

ABSTRACT

Objective:To explore the influence of ulinastatin combined with thymosinα1 on the immune function of patients with a-cute brain injury. Methods:Sixty-eight cases of patients with acute brain injury were divided into the control group and the observation group randomly with thirty-four ones in each. The control group was given the routine treatment, and the observation group was given ulinastatin combined with thymosinα1 additionally. After the 1-day, 3-day, 7-day and 14-day treatment, transforming growth factor-β1 (TGF-β1), interleukin-6(IL-6), interleukin-10 (IL-10), tumor necrosis factor-α (TNF-α) and the other serum inflammatory cyto-kine levels, and CD4 +, CD8 +, CD4 + /CD8 +, HLA-DR and cellular immune index levels were detected in the two groups. The prog-nosis effects were evaluated by the prognostic classification of brain injury, and the adverse reactions were analyzed in the two groups as well. Results:After the 1-day treatment, there were no significant differences in the serum inflammatory cytokines and immune param-eters between the groups (P>0. 05). After the 3-day, 7-day and 14-day treatment, serum TGF-β1, IL-6, IL-10 and TNF- α levels were higher than those on the first day after the treatment, and TGF-β1 showed an increasing trend with time extension, while IL-6, IL-10, TNF-α and CD4 + and CD4 + /CD8 +rose first and then decreased. After the 3-day, 7-day and 14-day treatment, serum IL-10 and CD4 +levels in the observation group were significantly higher than those in the control group, and IL-6 and TNF-αlevels were signifi-cantly lower than those in the control group (P<0. 05). After the 3-day and 14-day treatment, CD4 + and CD8 + levels in the observa-tion were significantly higher than those in the control group, and after the 7-day and 14-day treatment, HLA-DR levels were signifi-cantly higher than those in the control group (P<0. 05). The prognosis effect of the observation group was better than that of the con-trol group with statistically significant difference (P<0. 05). Conclusion:Ulinastatin combined with thymosin α1 is used to treat the patients with acute brain injury with better cellular immune function improvement and prognosis effect, which is worthy of clinical popu-larization and application.

ABSTRACT

[Objective] To investigate the effects of airway dysbacteriosis on the development of murine atlergic airway diseases (AAD).[Methods] Female C57BL/6 mice were neubulized with Vancomycin for 10 days and then were sacrificed.The bacterial population in bronchoalveolar lavage fluid (BALF) were evaluated using 16S rRNA high-throughput sequencing technology,exploriug the method of establishing an airway dysbacteriosis mouse model.After the mouse model was established successfully,airway dysbacteriosis mouse models were established by the same method,and based on that,the mice were sensitized and challenged with ovalbumin (OVA) to induce airway allergic inflammation.The frequency of nasal rubbing behaviors per mice was counted;the total cell number and eosinophil relative abundance in BALF were evaluated;the lung tissue inflammation and goblet cell metaplasia were assessed according to histopathological features;and the IgE level in serum,IFN-γ,IL-4 and IL-5 levels in BALF,and IL-33 levels in serum,BALF and intestine tissue were measured by ELISA.[Results] Nebulization of Vancomycin increased Bradyrhizobium,Sphingopyxis,Cupriavidus,Pelomonas,and decreased Akkermansia and Prevotella_6 in airway,inducing significant airway dysbacteriosis.Using the animal model,further study found that airway dysbacteriosis exacerbated OVA-induced airway allergic inflammation,including increased nasal rubbing frequency,higher serun IgE level,more total cell count especially eosinophil infiltration,more serious lung tissue inflammation and goblet cell metaplasia.Additionally,compared to OVA group,mice in Dysbacteriosis and OVA group had significantly increased level of Th2 cytokine IL-4 and IL-5,and significantly decreased Thl cytokine IFN-γin BALF,which revealed that mice in Dysbacteriosis and OVA group had mote remarkable Thl/Th2 imbalance.Furthermore,IL-33 level showed a significant increase in BALF,but didn't change in serum or intestine tissue in Dysbacteriosis and OVA group compared to OVA group.Indicating that airway dysbacteriosis may only affect the local production of IL-33.[Conclusions] An airway dysbacteriosis mouse model was established by Vancomycin nebulization successfully.Airway dysbacteriosis may activate innate lymphoid cells (ILC) and Th2 cell by inducing local IL-33 secreting,which leads to the imbalance of Th1/Th2,and in turn promotes the development of AAD.

ABSTRACT

Exercise is one of the important techniques of cardiovascular rehabilitation. Exercise can reduce inflammatory response to improve endothelial function, and improve mitochondrial function to increase myocardial cell activity. For cardiovascular risk factors, exer-cise can promote the activity of lipoprotein, increase the level of high-density lipoprotein;improve the function of insulin receptor to reduce insulin resistance, reduce platelet aggregation and improve endothelial function to reduce blood pressure. For the respiratory system, aerobic exercise can improve the function of respiratory muscle, thus relieve the dyspnea. Exercise can promote the activation of immune factor and increase metabolism, to increase immune function and anti-aging. Resistance exercise can improve mitochondrial function and promote fi-ber type conversion, to improve the function of skeletal muscle system.

ABSTRACT

Background and purpose:Adenocarcinoma of the esophagogastric junction (AEG) has a high incidence of early recurrence and metastasis after operation. The prognosis of AEG is poor. However, few studies have investigated the recurrence of AEG. The purpose of this study was to clarify the important clinical pathological factors affecting the early recurrence ofⅠ,Ⅱ type of AEG after operation. Thus more active treatment for patients at high risk of recurrence may improve the prognosis.Methods:This study retrospectively reviewed the clinical data from 145 AEG patients who underwent R0 resection during the period from Dec. 2008 to Dec. 2012. Risk factors associated with the early recurrence were analyzed.Results:The mean time to tumor recurrence was 25.4 months after R0 resection, and the 1-year recurrence rate was 38.6%. Univariate analysis showed that the histological grade (degree of tumor differentiation), number of positive lymph nodes, TNM stage and vascular invasion were signiifcantly related with the early recurrence (P<0.05). Logistic multivariate regression analysis showed that only histological grade and vascular invasion were independently related with early tumor recurrence (P<0.05).Conclusion:Histological grade and vascular invasion are independent risk factors for predicting the early tumor recurrence after R0 resection for AEG.
