ABSTRACT

Objective:To summarize the clinical characteristics and prognosis of acute hyperextension spinal cord injury (SCI) in children, and to provide some recommendations for the treatment and prevention of this disease.Methods:Reviewed the data of children of SCI after sustained or repeated hyperextension of the spine at Wuhan Union Hospital and Wuhan Children's Hospital from September 2010 to September 2020. According to the American Spinal Injury Association impairment scale (AIS grade), the patients were divided into complete SCI group and incomplete SCI group. The age, symptoms and evolution after injury, neurological level of injury, imaging data, laboratory examination data, prognosis and complications of the two groups were analyzed. Retrospectively summarize the characteristics of this type of injury.Results:Forty-four cases of acute hyperextension SCI in children were included. Their age ranged from 3 to 10 years old, 95% of them were under 8 years old and 95% of them were female. There was no significant difference in age at injury and time of dance training between children with complete SCI and incomplete SCI. Back and leg pain, lower limb weakness or paresthesia, and rapidly progress to complete or incomplete SCI in a short period were typical symptoms. All blood test results anddiagnostic analysis of cerebrospinal fluid were unremarkable or negative. There was no fracture or dislocation in the whole spine. Magnetic resonance imaging showed a longitudinally extended intramedullary high-intensity signal in the thoracolumbar spinal cord. Complete SCI accounted for 60% of all cases, and the prognosis was poor with spinal cord atrophy and various complications.Conclusion:Children younger than 10 years old after sustained or repeated hyperextension of the spine may suffer acute hyperextension SCI. Children with complete SCI have poor prognosis and serious complications. Therefore, prevention of this type of injury is the best strategy.

ABSTRACT

Objective:To investigate the predictive value of inflammatory markers for the risk of stroke-associated infection (SAI) in patients with anterior circulation large vessel occlusive stroke who received endovascular therapy.Methods:Patients with anterior circulation large vessel occlusive stroke received endovascular treatment in Nanjing First Hospital, Nanjing Medical University from 2016 to 2020 were retrospectively enrolled. The clinical data of SAI group and non-SAI group were compared. Multivariate logistic regression analysis was used to screen the independent influencing factors of SAI, and then the predictive nomogram was established according to these influencing factors to verify its clinical application efficiency. Results:A total of 409 patients were enrolled during the study. Their age was 71.3±11.7 years, and 250 were male (61.1%). The median baseline Naitonal Institutes of Health Stroke Scale (NIHSS) score was 16. One hundred and nineteen patients (29.1%) received intravenous thrombolysis, 376 (91.9%) were successfully recanalized after endovascular therapy, and 293 (71.6%) developed SAI. Univariate analysis showed that age, atrial fibrillation ratio, NIHSS score at admission, fasting blood glucose, triglyceride, high sensitivity C reactive protein (hs-CRP), leukocyte count, neutrophil count, neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) were significantly higher than those in the non-SAI group (all P<0.05). Multivariate logistic regression analysis showed that age, NIHSS score at admission, fasting blood glucose, hs-CRP, leukocyte count, neutrophil count and NLR were the independent influencing factors of SAI ( P<0.05). Receiver operating characteristics curve analysis showed that the predictive value of multiple inflammatory markers (hs-CRP, leukocyte count, neutrophil count and NLR) for SAI was significantly better than that of the single inflammatory marker ( P<0.01). The area under the curve was 0.782 (95% confidence interval 0.719-0.846), and the predictive sensitivity and specificity were 80.6% and 64.5% respectively. Decision curve analysis showed that compared with the traditional indicators, the predictive nomogram based on inflammation related indicators (hs-CRP, leukocyte count and NLR) had a higher net profitability for predicting SAI. Conclusion:The hs-CRP, leukocyte count and NLR can be used to predict the risks of SAI in patients with acute ischemic stroke receiving endovascular therapy.

ABSTRACT

OBJECTIVE@#To investigate the effect of two different approaches ERRα strategy on the apoptosis in multiple myeloma cell line MM.1S.@*METHODS@#For the one strategy, shRNA was mediated by lentivirus. Stable cell clones were established by transfecting the lentivirus into MM.1S cells and screened by puromycin. For the other strategy, XCT790, a specific reverse agonist of ERRα, was used to treat MM.1S cells. The apoptosis of the cells was analyzed by flow cytometry after ERRα was down-regulated. Western blot assay was used to detect the apoptosis of related proteins.@*RESULTS@#The knocked down ERRα was achieved, lentivirus with shERRα were successfully infected into MM.1S and ERRα was reduced significantly. Knockdown of ERRα could induce MM.1S cell apoptosis dramatically. Meanwhile, the expression of cleaved PARP (a kind of apoptosis related markers) was significantly increased following depletion of ERRα in MM.1S cells. XCT790 could significantly down-regulate the expression of ERRα protein in MM.1S cells, which was consistent with the effect caused by shRNA.@*CONCLUSION@#Interference the expression of ERRα by shRNA or XCT790 can induce apparent apoptosis in MM.1S cells, which indicating that ERRα is crucial for the survival of myeloma cells.

ABSTRACT

This Meta-analysis was designed to evaluate the effects of Bailing Capsules on microinflammation and nutritional status of maintenance hemodialysis patients, and to determine its efficacy and safety. The randomized controlled trials concerning the intervention of microinflammation and nutritional status in maintenance hemodialysis patients with Bailing Capsules were searched from Chinese and English databases including CNKI, Wanfang, VIP, PubMed, EMbase, and Cochrane Library. A total of 16 articles were obtained, involving 1 095 cases. As revealed by Meta-analysis,(1)Bailing Capsules lowered the levels of serum high sensitivity C-reactive protein(SMD=-0.92, 95%CI[-1.05,-0.80], P<0.000 01), interleukin-6(SMD=-1.49, 95%CI[-1.96,-1.02], P<0.000 01), and tumor necrosis factor-α(SMD=-1.48, 95%CI[-1.68,-1.28], P<0.000 01) in patients with maintenance hemodialysis, thus alleviating microinflammation.(2)Bailing Capsules elevated the levels of serum hemoglobin(SMD=1.37, 95%CI[1.21, 1.54], P<0.000 01), albumin(SMD=0.78, 95%CI[0.57, 0.98], P<0.000 01), and triglyceride(SMD=0.29, 95%CI[0.07, 0.50], P=0.01) in patients with hemodialysis to improve their nutritional status.(3)Bailing Capsules reduced the incidence of cardiovascular events(RR=0.45, 95%CI[0.34, 0.59], P<0.000 01).(4)A total of six patients presented with mild gastrointestinal discomfort after receiving Bailing Capsules, and no serious adverse reactions were observed. The sequential analysis showed that the sample size of this Meta-analysis had reached the expected value. Meanwhile, the grade of evidence quality suggested that the outcome indicators were mainly low or extremely low in quality. In conclusion, Bailing Capsules might have potential advantages in alleviating microinflammation, improving nutritional status, and reducing the incidence of cardiovascular events. However, in view of the low quality and evidence of the included literature, high-quality clinical trials are needed to further confirm the efficacy and safety of Bailing Capsules.

ABSTRACT

The development of nanotechnology has made it possible to develop safe, efficient, precise and controllable drug delivery system (DDS). Among them, organic or inorganic synthetic nanocarriers have been widely reported and used for the delivery of tumor therapeutic agents. However, some of carriers have several problems, such as easily eliminated by the body's immune system, difficult to preparation or poor safety in vivo. In recent years, with the development of biomedicine, biomimetic technology based biomembrane-mediated nanodrug delivery has organically integrated the low immunogenicity of natural biomembrane, cancer targeting, and the controllable and multifunctional of smart nanocarrier design. It will achieve a new breakthrough of nanotechnology in cancer targeted therapy. Based on the recent advances of cell membrane-derived biomimetic nanotechnology and the nanomedicine in the field of cancer therapy, this review discusses the three aspects including the experimental basis of cell membrane-derived biomimetic nanotechnology, the classification of biomimetic nanodrug delivery platforms, and the application in cancer targeted therapy. Therefore, the review will provide reference for the design of smart drug delivery system and its development in cancer targeted treatment.

ABSTRACT

Objective:To investigate the predictive values of serum hypersensitive C-reactive protein (hs-CRP) and lipoprotein-associated phospholipase A 2 (Lp-PLA 2) for early neurological deterioration (END) and parenchymal hematoma (PH)-type 2 hemorrhagic transformation (HT) after intravenous thrombolysis in patients with acute ischemic stroke. Methods:Patients with acute ischemic stroke treated with intravenous thrombolysis in the Department of Neurology, Nanjing First Hospital, Nanjing Medical University from January 2018 to January 2021 were enrolled retrospectively. END was defined as an increase of ≥4 in the National Institutes of Health Stroke Scale (NIHSS) score at 24 h after thrombolysis compared with the baseline. PH-2 type HT was defined as parenchymal hematoma with obvious space occupying effect or hemorrhage at the distant site of infarct. Multivariate logistic regression analysis was used to determine the independent influencing factors of END and PH-2 type HT. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of hs-CRP and Lp-PLA 2 levels for END and PH-2 type HT. Results:A total of 804 patients with acute ischemic stroke treated with intravenous thrombolysis were included, of which 63 (7.8%) developed END within 24 h after intravenous thrombolysis; 41 (5.1%) developed HT, of which 38 were PH-2 type HT. Univariate analysis showed that the levels of serum hs-CRP and Lp-PLA 2 in the END group were significantly higher than those in the non-END group (all P<0.05), and the levels of serum hs-CRP and Lp-PLA 2 in the PH-2 HT group were significantly higher than those in the non-PH-2 HT group ( P<0.05). Multivariate logistic analysis showed that hs-CRP (odds ratio [ OR] 1.017, 95% confidence interval [ CI] 1.001-1.034; P=0.043) and Lp-PLA 2 ( OR 1.002, 95% CI 1.000-1.003; P=0.020) were the independent risk factors for END after intravenous thrombolysis. In addition, hs-CRP ( OR 1.019, 95% CI 1.002-1.036; P=0.027) and Lp-PLA 2 ( OR 1.002, 95% CI 1.000-1.003; P=0.018) were also the independent risk factors for PH-2 HT after intravenous thrombolysis. The ROC curve analysis showed that the areas under the curve of hs-CRP and Lp-PLA 2 for predicting END were 0.675 (95% CI 0.609-0.741; P<0.001) and 0.606 (95% CI 0.528-0.683; P=0.005) respectively, and the areas under the curve for predicting PH-2 HT were 0.641 (95% CI 0.545-0.737; P=0.003) and 0.600 (95% CI 0.500-0.699; P= 0.051) respectively. Conclusion:Higher baseline serum hs-CRP and Lp-PLA 2 are the independent predictors of END and PH-2 type HT after intravenous thrombolysis in patients with acute ischemic stroke.

ABSTRACT

Objective:To investigate the risk factors of pancreatic pseudocyst (PPC) in patients with severe acute pancreatitis (SAP).Methods:The clinical data of 142 SAP patients treated in the First Affiliated Hospital of Chongqing Medical University from January 2015 to December 2019 were collected and retrospectively analyzed. The patients were divided into two groups: group with PPC ( n=48) and group without PPC ( n=94) according to whether they were complicated with PPC. The sex, age, body mass index, etiology, past history of diabetes or pancreatitis, modified CT severity index (MCTSI) score within 3 to 10 days of the onset, APACHEⅡ score within 48 hours of admission, fasting time, oxygenation index, hematocrit, white blood cell count, the percentage of neutrophil, serum procalcitonin (PCT), the levels of albumin, urea nitrogen(BUN), serum calcium, lactate dehydrogenase and creatinine, whether complicated with ascites and whether hemofiltration treatment was performed within 24 hours after admission were recorded. Univariate analysis and multivariate logistic stepwise regression were used to analyze the independent risk factors of PPC formation after SAP. The receiver operating characteristic curve (ROC) was drawn and the area under the curve (AUC) was calculated to evaluate the efficacy of each index in predicting the formation of PPC in patients with SAP. Results:Univariate analysis showed that PPC formation significantly correlated with MCTSI score, APACHEⅡ score, fasting time, PCT, serum albumin, BUN, lactate dehydrogenase, creatinine, serum calcium level and ascites ( P<0.05). Multivariate regression analysis showed that MCTSI score ( OR=1.81, 95% CI 1.273-2.571, P=0.001) and fasting time ( OR=1.083, 95% CI 1.002-1.171, P=0.044) were the risk factors for PPC formation in SAP patients. Serum albumin ( OR=0.875, 95% CI 0.781-0.979, P=0.02) and serum calcium ( OR=0.02, 95% CI 0.002-0.178, P<0.001) were the protective factors for PPC formations. AUC predicted by MCTSI score, fasting time, serum albumin and serum calcium levels for PPC formations in patients with SAP were 0.783 (95% CI 0.706-0.860), 0.650 (95% CI 0.553-0.746), 0.809(95% CI 0.738-0.881) and 0.855(95% CI 0.795-0.915) respectively, and the best cut-off values predicted were 7 points, 17.5 days, 33.5 g/L and 1.79 mmol/L. Conclusions:MCTSI score >7, fasting time >17.5 days, hypocalcemia and low albumin level were the independent risk factors for SAP complicated with PPC, which need close follow-up and timely intervention.

ABSTRACT

The increasing burden of cardiovascular disease in China has become a major public health problem, and the prevention and treatment of cardiovascular disease is in urgent need. For the reality of integrated Chinese and Western medicine in the Chinese health care system, we can consider the service ability of traditional Chinese medicine. Xueshuan Xinmaining Tablet is a kind of Chinese patent medicine commonly used in the treatment of recovery stage of ischemic stroke and angina pectoris of coronary heart disease. Based on the data of hospitalized patients covered by national urban basic medical insurance of China Medical Insurance Research Association in 2013, this study evaluated the treatment cost and detailed composition of the cost for the patients with cerebral infarction and coronary heart disease treated by Xueshuan Xinmaining Tablets. At the same time, the differences in disease burden and direct medical expenses among Xueshuan Xinmaining Tablets group, Western medicine group and another commonly used Chinese patent medicine group were analyzed. Among the three groups of patients with cerebral infarction and coronary heart disease, the hospitalization rates caused by various causes(44.4% and 29.6%) and diseases(20.8% and 5.2%) in Xueshuan Xinmaining Tablets group were the lowest(all P<0.01), and the number of hospitalization times in half a year was highest in the common Chinese patent medicine group(all P<0.01). In patients with cerebral infarction, the median annual total outpatient expenses were 7 476.8, 7 601.8, 15 650.1 yuan respectively in Western medicine group, Xueshuan Xinmaining Tablets group and the common Chinese patent medicine group(P<0.01), and the median hospitalization expenses were 11 620.2, 14 988.9, 13 325.6 yuan respectively(P=0.058). In patients with coronary heart disease, the total outpatient expenses of the three groups were 6 831.4, 10 228.6, 13 132.4 yuan respectively(P<0.01), and the total hospitalization expenses were 13 354.7, 14 911.5, 15 725.3 yuan respectively(P=0.134). The results showed that in patients with cerebral infarction and coronary heart disease, the hospitalization rate was lowest in Xueshuan Xinmaining Tablets group, beneficial to the turnover of hospital beds and full use of hospital medical resources. The total annual outpatient cost of Xueshuan Xinmaining Tablets group was lower than that of common Chinese patent medicine group, beneficial to reduce the burden of disease.

ABSTRACT

Objective:To analyze the clinical characteristics and risk factors of fungal infections secondary to severe acute pancreatitis (SAP), so as to provide experience for clinical diagnosis and treatment.Methods:From January 2013 to August 2020, at The First Affiliated Hospital of Chongqing Medical University, 48 SAP patients with secondary fungal infection (infection group) were enrolled. At the same period, 72 SAP patients without fungal infection (non-infection group) were selected as control group. The location of fungal infection, bacterial species distribution, anti-fungal treatment of the infection group, and the prognosis of the two groups were analyzed. Independent sample t test, Wilcoxon rank sum test and chi-square test were used for statistical analysis. The factors that may affect the secondary fungal infection of SAP were analyzed by binary logistic regression analysis in order to detect the independent risk factors of SAP with secondary fungal infection, and receiver operating characteristic curve analysis was performed to evaluate their value in predicting SAP with secondary fungal infection. Results:There were 74 fungal infection sites in the infection group, mainly respiratory infections (25.7%); 54 fungal strains were isolated and all of which were Candida infection, mainly Candida albicans (48.1%). In the infection group, 36 patients received antifungal therapy, among whom 20 patients (55.6%) died; the remaining 12 patients did not receive antifungal therapy, six of them died, in total 26 (54.2%) patients died. In the non-infection group there were nine patients (12.5%) died. There was a significant difference in mortality between the infection group and the non-infection group (54.2% vs. 12.5%, χ2=24.20, P<0.01). Compared with the non-infection group, the acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score at admission, time of fasting and drinking, time of urinary catheter catheterization and deep venous catheterization, types and duration of broad-spectrum antibiotics usage, hospital stay, time of invasive ventilator using and indwelling time of abdominal drainage tube were higher in the infection group ((16.92±5.70) point vs. (13.32±4.73) point, (16.38±6.87) d vs. (9.51±4.90) d, (15.65±9.68) d vs. (10.40±9.45) d, (19.48±10.43) d vs. (12.74±10.28) d, (4.13±1.02) type vs. (2.35±1.78) type, (30.54±12.94) d vs.(19.10±9.48) d, (36.10±26.27) d vs.(21.93±9.91) d, 6.00 d (0.00 d, 21.75 d) vs. 0.00 d(0.00 d, 7.00 d), 9.00 d (0.00 d, 18.00 d) vs. 0.00 d (0.00 d, 0.00 d)), and the differences were statistically significant ( t=-3.61, -6.56, -3.08, -3.82, -6.86, -5.06 and -3.95, Z=-2.71 and -4.19, all P<0.01). The results of binary logistic regression analysis showed that APACHEⅡ score at admission, time of fasting and drinking, and broad-spectrum antibiotic usage were independent risk factors of SAP with secondary fungal infection (odds ratio=1.181, 2.589 and 1.205, 95% confidence interval ( CI) 1.036 to 1.347, 1.409 to 4.757 and 1.060 to 1.370), and the differences were statistically significant (all P<0.05). The area under curve values of APACHEⅡ score, broad-spectrum antibiotics usage and time of fasting and drinking were 0.695 (95% CI 0.596 to 0.794), 0.853 (95% CI 0.784 to 0.923) and 0.907 (95% CI 0.798 to 0.923), respectively; and the cut-off values at 17.5 point, 3.5 types, and 11.5 d were most effective in predicting secondary fungal infection of SAP. Conclusions:Respiratory tract is the most common site for secondary fungal infections in SAP. Candida albicans infection is more common. SAP patients with APACHE Ⅱ score >17 point at admission, time of fasting and drinking >11 d and more than three kinds of broad-spectrum antibiotics application are prone to secondary fungal infections in the later stage.

ABSTRACT

OBJECTIVE@#To estimate the prevalence rate of bone and joint injury in China and to describe the three-dimension distribution of the disease (area, time and people).@*METHODS@#Based on a cross-sectional design, a retrospective study was conducted by using Chinese basic medical insurance database from January 1, 2013 to December 31, 2017 to analyze the epidemiological characteristics of bone and joint injury. The prevalence rate of bone and joint injury in each city was calculated, and then using meta-analyses to estimate the pooled prevalence of each area and the whole country. The pooled prevalence rates were compared among the different groups of populations, in terms of geographical area, time and population characteristics (age and gender).@*RESULTS@#A total of 28 419 264 subjects were included in this study, including 705 793 patients with bone and joint injury. From 2013 to 2017, in Chinese basic medical insurance database, the overall prevalence rate of bone and joint injury was 141.5(95%CI: 90.4-203.7) per 10 000 population, and the prevalence rates of non-specific or polyarticular disease, knee disease, and shoulder disease were 101.6 (95%CI: 63.5-148.4)per 10 000 population, 22.5(95%CI:15.1-31.4)per 10 000 population and 10.9 (95%CI: 6.4-16.4)per 10 000 population. The prevalence rates varied across the areas, the highest rate was observed in North China, with the prevalence of 310.6 (95%CI: 12.6-989.7) per 10 000 population, and the lowest rate was observed in Southwest China, with the prevalence of 59.0 (95%CI: 37.5-85.2) per 10 000 population. The prevalence rate of bone and joint injury increased over the study period, from 111.1 (95%CI: 56.0-182.5)per 10 000 population in 2013 to 175.5 (95%CI: 116.8-245.5)per 10 000 population in 2017. The prevalence of bone and joint injury in the female population was 149.1 (95%CI: 94.2-215.9) per 10 000 population, which was higher than that of men [133.6(95%CI: 86.2-190.9) per 10 000 population]. The higher prevalence of knee disease, unspecified or polyarticular disease, and bone and joint injury were observed in people aged 60 years and older, while the prevalence of shoulder disease peaked in 40-59 years old people [20.6 (95%CI: 12.5-30.5) per 10 000 population].@*CONCLUSION@#This study reported a relative low prevalence of bone and joint injury in China from 2013 to 2017. The prevalence increased over the study period, and the highest prevalence rate was observed in North China. The prevalence rate showed differences among different groups of populations, and higher rates were observed in females and people aged 60 years and older.

ABSTRACT

OBJECTIVE@#To observe the clinical prognosis and surgical treatment results in patients with postinfarction ventricular septal rupture, and to discuss the risk factors, methods & timing of treatment.@*METHODS@#From January 2006 to February 2019, 23 patients with postinfarction ventricular septal rupture were admitted to the department of cardiac surgery, Peking University People's Hospital, including 12 males (52.2%) and 11 females (47.8%), aged (64.26 ±11.09) years. Among them, 18 cases underwent operation, and 5 cases did not receive surgical treatment. The clinical data and follow-up data were summarized retrospectively.@*RESULTS@#Among the patients treated with operation, the average time from perforation to operation was (19.39 ±13.67) d, including 6 cases (33.3%) of perforation within 1 week, 6 cases (33.3%) within 2 to 4 weeks and 6 cases (33.3%) more than 4 weeks. Emergency surgery was performed in 11 cases (61.1%) because of hemodynamic instability, and selective operation in 7 cases (38.9%). Direct enlarged patch was used in 13 cases (72.2%), and some infarct exclusion techniques were used in 5 patients (27.8%). In 18 cases, coronary artery bypass grafting was performed in 12 cases (66.7%). Of all the surgical patients, 7 (38.9%) died during hospitalization. Compared with the survival patients, the perioperative death patients had earlier perforation [(1.83±0.75) d vs. (5.22 ±4.66) d, P=0.019] and higher emergency operation rate (100% vs. 36.4%, P=0.009) and lower simultaneous bypass grafting rate (28.6% vs. 90.1%, P=0.008). The median follow-up time was 2 years (3 months to 10 years). 2 patients died of heart failure in 2 months after operation, and 9 cases (50.0%) survived for a long time. Of the 5 patients who had not been treated, 2 died while waiting for operation, and 3 patients who refused surgery died within 1 week after discharge.@*CONCLUSION@#Surgery is an effective treatment for patients with acute myocardial infarction complicated with ventricular septum perforation. The best time for operation should be determined by real-time evaluation and monitoring, combined with the situation of patients. Concomitant coronary artery bypass grafting may be beneficial to these patients.

ABSTRACT

OBJECTIVE@#To investigate and analyze the relationship between intraoperative graft flow measurements and the early mid-term outcomes after off-pump coronary artery bypass grafting (OPCAB).@*METHODS@#Patients who underwent isolated OPCAB in the Department of Cardiac Surgery of Peking University People's Hospital from January 2013 to June 2016 were included. Perioperative characteristics, graft flow measurements and postoperative follow-up outcomes were retrospectively collected. Comparison was made between flow measurements of grafts and the early mid-term outcomes. Flow measurements of grafts included the mean flow (MF) and the pulsatility index (PI). The early outcomes included peri-operative myocardial infarction (PMI), use of an intra-aortic balloon pump (IABP), reoperation for all causes, new-onset atrial fibrillation and in-hospital or 30-day mortality.@*RESULTS@#A total of 463 patients were included in the study. Mean age was (62.80±8.36) years, and 24.8% were females. The total number of grafts was 1 435, which averaged 3.10 grafts per patient. The MF and PI were separately (32.34±14.45) mL/min and 2.87±0.92. Of all the patients, 23(5%) had PMI, and 11 used IABP. Observed in-hospital or 30-day mortality was 0.86% (4 patients). Compared with non-PMI group, the MF was lower and the PI was higher in the PMI group (P<0.05). However, the differences of other early outcomes had no statistical significance between the PMI group and the non-PMI group. The lower MF (Wald=5.684, P=0.017, 95%CI: 0.894-0.989) and the higher PI (Wald=9.040, P=0.003, 95%CI: 1.252-2.903) were risk factors of PMI in multivariable Logistic regression modeling. The longest follow-up time was 37 months, and 7 patients died. The differences of graft flow measurements between the surviving group and the nonsurvivors had no statistical significance, but overall mid-term survival was lower in patients with poor left internal mammary artery (LIMA) to left anterior descending artery (LAD) graft flow (MF<10 mL/min; OR=9.6, P<0.05).@*CONCLUSION@#Intraoperative graft flow parameters during OPCAB can predict the early mid-term outcomes. The lower MF and the higher PI should increase the rate of PMI. A lower flow of LIMA to LAD graft (<10 mL/min) should increase the rate of midterm mortality, but further research will be needed to confirm and explore the findings.

ABSTRACT

Objective To investigate the characteristics of pathogens and risk factors of severe acute pancreatitis (SAP) complicated with infection,so as to provide reference for clinical diagnosis and treatment.Methods From February 2011 to January 2018,at the First Affiliated Hospital of Chongqing Medical University,438 patients with SAP were selected.The samples including ascites,sputum and blood were collected and cultured.Distribution and drug resistance of pathogens were analyzed.Chi-square test and logistic regression analysis were used for analyzing the risk factors related to SAP complicated with infection.Results The total infection rate of SAP was 49.09% (215/438),of which the bacterial infection rate was 44.29% (194/438) and the fungal infection rate was 22.60% (99/438).A total of 625 pathogens were cultured,including 333 (53.28%) strains of Gram-negative bacteria,171 (27.36%) strains of Grampositive bacteria and 121 (19.36%) strains of fungi.Gram-negative bacteria were extremely resistant to β-lactams antibiotics,among them Acinetobacter baumannii was the highest (63.93% to 100.00%),and resistance rate to enzyme inhibitors was slightly lower (11.54% to 48.15%).The resistance rates of Grampositive bacteria to penicillin and erythromycin were both high,which were 92.86% to 100.00% and 81.25% to 95.00%,respectively,and Gram-positive bacteria resistant to vancomycin,linezolid,and tigecycline were not found.The resistance rate of fungi was generally low (0 to 28.57%).The results of logistic regression analysis showed that multiple organ dysfunction syndrome (MODS) (odds ratio (OR) =2.031,95% confidence interval (CI)1.230 to 3.356),acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score≥11 (OR =1.780,95%CI 1.129 to 2.806),fasting time more than three weeks (OR =3.437,95% CI 2.119 to 5.574),mechanical ventilation (OR =2.697,95% CI 1.643 to 4.427) and surgery (OR =3.464,95% CI 1.806 to 6.643) were the independent risk factors of SAP complicated with infection (all P < 0.05).The results of stratified analysis indicated that MODS,fasting time more than three weeks,mechanical ventilation and surgery were the independent risk factors of more locus infection (all P <0.05).Conclusions The infection rate of SAP is high and the risk factors are complex.Early prevention,improvement of the pathogen detection and guiding the reasonable use of antibiotics are necessary.For patients with invasive procedures and treatment,aseptic awareness should be strengthen to prevent iatrogenic infection.

ABSTRACT

Non-syndromic cleft lip with/without cleft palate (NSCL/P) is a common congenital disease worldwide, and its etiology is related to the combination of genetic and environmental factors. Although genome-wide association analysis did not involve Single Nucleotide Polymorphisms (SNPs) in Wnt genes, it has been reported that SNPs in Wnt genes are related to NSCL/P, and the study of SNPs of Wnt genes and its corresponding phenotypic effect is helpful to explain the etiological mechanism of NSCL/P. In recent years, Wnt3 gene related to NSCL/P, rs142167, rs3809857, rs9890413 and other teratopoietic single nucleotide loci are the main teratopoietic single nucleotide loci studied most, and the research conclusions on the correlation between Wnt3 gene polymorphism and NSCL/P are obviously different in different populations. This paper reviews the research progress on the correlation between Wnt3 gene polymorphism and NSCL/P.

ABSTRACT

Objective To explore the clinical manifestation,treatment and prognosis of patients with acute superior mesenteric artery embolism (ASMAE).Methods From October 2012 to March 2018,the clinical data of 66 patients with ASMAE who were admitted to The First Affiliated Hospital of Chongqing Medical University were collected and retrospectively analyzed.The patients were divided into the death group and the survival group according to whether they died during hospitalization.The clinical features,the time of diagnosis and treatment methods of two groups were compared.T-test and chi-square test were performed for statistical analysis.Results Among 66 ASMAE patients,16 were in the death group and 50 in the survival group.The age of the death group was (75.6 ± 9.9) years,which was greater than that of the survival group ((68.1 ±13.2) years),and the difference was statistically significant (t =1.998,P =0.041).Among 16 dead patients,the case numbers of diagnosis time less than six hours,complicated with atrial fibrillation,peritoneal irritation sign,weakened or disappeared bowel sounds and complicated with systemic inflammatory response syndrome were 0,14,9,9 and 16,respectively.However,among 50 survival patients,the case numbers of diagnosis time less than six hours,complicated with atrial fibrillation,peritoneal irritation sign,weakened or disappeared bowel sounds and complicated with systemic inflammatory response syndrome were 15 (30.0%),30 (60.0%),14 (28.0%),14 (28.0%) and 36 (72.0%),respectively.The differences between two groups were all statistically significant (x2 =4.621,4.125,4.261,4.261 and 4.134,all P < 0.05).Conclusions When sudden severe abdominal pain occurs in elderly patients with atrial fibrillation,ASMAE should be alerted.Early (less than six hours) and correct diagnosis can improve the prognosis of the ASMAE patients.

ABSTRACT

BACKGROUND@#There are few reports of peri-operative application of intra-aortic balloon pumping (IABP) in patients with coronary artery disease (CAD) and different grades of left ventricular dysfunction. This study aimed to analyze the early outcomes of peri-operative application of IABP in coronary artery bypass grafting (CABG) among patients with CAD and left ventricular dysfunction, and to provide a clinical basis for the peri-operative use of IABP.@*METHODS@#A retrospective analysis of 612 patients who received CABG in the General Hospital of People's Liberation Army between May 1995 and June 2014. Patients were assigned to an IABP or non-IABP group according to their treatments. Logistic regression analysis was performed to investigate the influence of peri-operative IABP implantation on in-hospital mortality. Further subgroup analysis was performed on patients with severe (ejection fraction [EF] ≤ 35%) and mild (EF = 36%-50%) left ventricular dysfunction.@*RESULTS@#Out of 612 included subjects, 78 belonged to the IABP group (12.7%) and 534 to the non-IABP group. Pre-operative left ventricular EF (LVEF) and EuroSCOREII predicted mortality was higher in the IABP group compared with the non-IABP group (P < 0.001 in both cases), yet the two did not differ significantly in terms of post-operative in-hospital mortality (P = 0.833). Regression analysis showed that IABP implantation, recent myocardial infarction, critical status, non-elective operation, and post-operative ventricular fibrillation were risk factors affecting in-hospital mortality (P < 0.01 in all cases). Peri-operative IABP implantation was a protective factor against in-hospital mortality (P = 0.0010). In both the severe and mild left ventricular dysfunction subgroups, peri-operative IABP implantation also exerted a protective role against mortality (P = 0.0303 and P = 0.0101, respectively).@*CONCLUSIONS@#Peri-operative IABP implantation could reduce the in-hospital mortality and improve the surgical outcomes of patients with CAD with both severe and mild left ventricular dysfunction.

The results of logistic regression analysis showed that multiple organ dysfunction syndrome (MODS) (odds ratio (OR)=2.031, 95% confidence interval (CI)1.230 to 3.356), acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ) score≥11 (OR=1.780, 95%CI 1.129 to 2.806), fasting time more than three weeks (OR=3.437, 95%CI 2.119 to 5.574), mechanical ventilation (OR=2.697, 95%CI 1.643 to 4.427) and surgery (OR=3.464, 95%CI 1.806 to 6.643) were the independent risk factors of SAP complicated with infection (all P<0.05). The results of stratified analysis indicated that MODS, fasting time more than three weeks, mechanical ventilation and surgery were the independent risk factors of more locus infection (all P<0.05).@*Conclusions@#The infection rate of SAP is high and the risk factors are complex. Early prevention, improvement of the pathogen detection and guiding the reasonable use of antibiotics are necessary. For patients with invasive procedures and treatment, aseptic awareness should be strengthen to prevent iatrogenic infection.

ABSTRACT

Objective@#To investigate the correlations of serum uric acid with outcomes and symptomatic intracranial hemorrhage (sICH) after intravascular mechanical thrombectomy bridged with intravenous thrombolysis in patients with ischemic stroke.@*Methods@#From January 2015 to January 2019, patients with acute ischemic stroke admitted to Nanjing First Hospital, Nanjing Medical University and underwent intravascular mechanical thrombectomy bridged with intravenous thrombolysis were analyzed retrospectively. Demographic characteristics, vascular risk factors, laboratory findings, National Institutes of Health Stroke Scale (NIHSS) scores, onset to treatment time, and whether sICH occurred were recorded. The modified Rankin Scale was used to evaluate the outcomes at 90 d after onset, and 0 to 2 was defined as good outcome. Multivariate logistic regression models were used to determine the independent factors for outcomes and sICH.@*Results@#A total of 144 patients were included, 54 (37.5%) had a good outcome, 90 (62.5%) had a poor outcome (including 28 deaths), and 29 (20.1%) had sICH. Serum uric acid was significantly higher in the good outcome group than in the poor outcome group (P<0.05). Serum uric acid was significantly higher in the non-sICH group than in the sICH group (P<0.05). Multivariate logistic regression analysis showed that higher serum uric acid were the independent protective factors of good outcome (odds ratio 0.82, 95% confidence interval 0.66-0.93; P<0.001) and sICH (odds ratio 0.97, 95% confidence interval 0.93-0.99; P=0.004).@*Conclusion@#High serum uric acid level is independently associated with good outcome after intravascular mechanical thrombectomybridged with intravenous thrombolysis in patients with acute ischemic stroke.
