ABSTRACT

Objective To analyze the in-hospital and long term prognosis of acute myocardial infarction(AMI)patients with N-terminal B-type brain natriuretic peptide(NT-proBNP)peak value exceeding the up-per limit.Methods A total of 669 patients with AMI diagnosed in a hospital from 2013 to 2018 were selected as research objects.According to the peak value level of NT-proBNP,they were divided into the NT-proBNP peak value exceeding the upper limit group(50 cases)and the NT-proBNP peak value detectable group(619 cases).Propensity score was used for matching(1:2),and the patients were divided into NT-proBNP peak value exceeding the upper limit group(50 cases)and NT-proBNP peak value detectable group(107 cases),and the in-hospital prognosis and long-term prognosis of the two groups were compared,as well as the echo-cardiographic indexes of each group in the acute stage and recovery stage of AMI.Multiple linear regression a-nalysis was used to predict the factors affecting left ventricular ejection fraction in the recovery stage of AMI.Results After matching the propensity score,compared with the NT-proBNP peak value detectable group,the neutrophil to lymphocyte ratio,hypersensitive C reactive protein level and fibrinogen level in the NT-proBNP peak value exceeding the upper limit group were higher at admission,and the differences were statistically sig-nificant(P<0.05).The proportion of Killip≥ Grade Ⅱ,left ventricular ejection fraction,hospitalization time and major adverse cardiovascular and cerebrovascular events in the NT-proBNP peak value exceeding the up-per limit group were compared with those in the NT-proBNP peak value detectable group,and the differences were statistically significant(P<0.05).The left ventricular ejection fraction and left ventricular shortening fraction of the NT-proBNP peak value detection group in AMI acute stage were higher than those in the NT-proBNP peak value exceeding the upper limit group in AMI acute stage,and the difference was statistically significant(P<0.05).Multiple linear regression analysis showed the relationship between the NT-proBNP peak value during hospitalization and the left ventricular ejection fraction of cardiac function during AMI re-covery.The results suggested that the NT-proBNP peak value was not a risk factor affecting the left ventricu-lar ejection fraction of cardiac function during AMI recovery.Conclusion AMI patients with NT-proBNP peak value exceeding the upper limit should be treated with a series of comprehensive treatment strategies to pro-mote their rehabilitation and improve their long-term prognosis.

ABSTRACT

Objective:To investigate the safety and efficacy of pseudomonas aeruginosa Injection (PAI) in the treatment of coeliac leakage after cervical lymph node dissection for robotic thyroid cancer.Methods:Retrospective analysis of 1262 patients who underwent robotic thyroid surgery at the 960th Hospital of the People’s Liberation Army from Jan. 2021 to Aug. 2023 was made. Postoperative celiac leakage happened in 28 patients. The control and injection groups were divided according to whether pseudomonas aeruginosa injection was used or not. In the control group, there were 4 males and 11 females out of 15 patients, with an average age of (46.20±9.02) years old, and the treatment methods of low-fat diet, negative pressure suction, and pressure bandage were used. In the injection group, there were 7 males and 6 females among 13 patients, with an average age of (41.00±8.87) years. They were treated with low-fat diet, negative pressure suction, pressure bandage, and PAI .The number of lymph node dissection, total drainage volume, peak drainage volume, days of hospitalization and the rate of decline in drainage volume within 24 h after the use of PAI in the injection group, post-injection temperature, number of injections, and post-injection extubation time were statistically analyzed in both groups. Independent samples t test, Mann-Whitney U test, χ2 test or Fisher’s exact test were used for comparison between groups. Results:There was no statistically significant difference in age, gender, extent of thyroidectomy, highest daily drainage volume, and total drainage volume between the two groups ( P>0.05). The difference in the number of lymph node dissection (49.15±23.05 vs. 30.80±11.76, P=0.012) and hospitalization time (11.77±4.64 vs. 16.40±6.42, P=0.041) between the injection group and the control group was statistically significant. After the use of pseudomonas aeruginosa injection, the draining fluid decreased from the previous day (69.56± 20.82) % in the injection group; Twelve patients were successfully extubated after one injection of pseudomonas aeruginosa injection, and one patient was successfully extubated after two injections; the mean time to extubation after injection was (3.85±1.28) days; 76.9% patients (10/13) had fever symptoms within 48 h with body temperature (38.05±0.89) ℃ after injection, body temperature returned to normal after symptomatic treatment,and no other adverse reactions occurred except fever. Conclusion:Pseudomonas aeruginosa injection is safe and effective in the treatment of celiac leakage after cervical lymph node dissection for robotic thyroid cancer, effectively reducing cervical drainage and shortening hospitalization days.

ABSTRACT

BACKGROUND:Acromion morphology is the most important external factor of degenerative rotator cuff tear,and studies on acromion morphology and acromion coverage have been continuing. OBJECTIVE:To investigate the coverage of acromion on rotator cuff tissue in three-dimensional space,measure coronal and sagittal parameters,and explore the relationship of acromial overhang,acromioglenoid angle and acromial coverage angle with degenerative full-thickness rotator cuff tears. METHODS:A total of 56 patients diagnosed with full-thickness rotator cuff tears by shoulder arthroscopic surgery or MRI in the Affiliated Hospital of Xuzhou Medical University from January 2022 to June 2023 were retrospectively collected as the tear group,while 48 patients with non-rotator cuff tear were included as the control group.Clinical data and chest CT data of the patients of the two groups were collected,and the shoulder blades of the patients were reconstructed using Mimics software.Acromial overhang,acromioglenoid angle and acromial coverage angle were measured in 3-matic software.The differences between the measurement parameters were compared between the two groups.Binary Logistic regression analysis and receiver operating characteristic curve analysis were performed to evaluate the ability of the measurement parameters to predict rotator cuff tear.It is generally believed that the parameter had good diagnostic value when the area under the receiver operating characteristic curve was greater than 0.8. RESULTS AND CONCLUSION:(1)The mean acromial overhang in patients with rotator cuff tears was greater than that in controls(P<0.001).The mean acromial coverage angle was also greater in patients with rotator cuff tears than in controls(P<0.001).There was no significant difference in the acromioglenoid angle between the two groups(P>0.05).(2)Binary Logistic regression analysis showed that acromial overhang and acromial coverage angle were both risk factors for rotator cuff tear(P<0.05).(3)Receiver operating characteristic curve analysis indicated that the areas under the curve of acromial overhang and acromial coverage angle were 0.725 and 0.865,respectively,and the optimal cutoff values were 36.15 mm and 60.65°.(4)The results showed that the acromial overhang and acromial coverage angle were greater in patients with rotator cuff tears than in patients without rotator cuff tears.Both were associated with degenerative full-thickness rotator cuff tears,and they could be used to predict rotator cuff tears,and the acromial coverage angle was more effective in predicting rotator cuff tears.

ABSTRACT

During the occurrence and development of various heart diseases,continuous deterioration of myocardial fibrosis leads to remodeling and dysfunction of the cardiac structure.As a newly discovered mechanically sensitive ion channel,Piezo1 has opened up a new field of research on cellular mechanical transduction.Piezo1 combines a fine force transducer with Ca2+ influx and participates in the regulation of cellular mechanical transduction,thereby regulating cellular biological functions.Recent studies have shown that the biomechanical changes induced by myocardial injury regulate the expression of Piezo1 in cardiomyocytes and cause an imbalance in calcium homeostasis,which plays an important role in the positive feedback loop of myocardial fibrosis.This review summarizes the theoretical basis and related studies of Piezo1 in regulating cardiac fibrosis and suggests that the Piezo1 channel may become a new target for the treatment of cardiac fibrosis,thereby providing a new research horizon for the prevention and treatment of cardiac fibrosis.

ABSTRACT

【Objective】 To observe the presence of ferroptosis in acute pancreatitis (AP) and the effect of iron ions on the NLRP3 pathway so as to explore the possible mechanisms for the protection of pancreatic alveolar cells. 【Methods】 A total of 45 male C57BL/6 mice were randomly divided into three groups (control, AP, and AP+2′2-bipyridyl). A total of 12 injections (caerulein, 50 μg/kg) were given at one-hour intervals. The AP+2′2-bipyridyl group was pretreated with 2′2-bipyridyl (20 mg/kg) for 1 hour, and then injected with caerulein. The control group was injected with an equal volume of normal saline. All of the mice were killed one hour after the last injection. Their pancreases were harvested for histopathological evaluation, immunohistochemistry analyses, and Western blotting. 【Results】 The ferroptosis inhibitor 2′2-bipyridyl could prevent the accumulation of iron ions, reduce the formation of lipid peroxides and the injury in the process of AP, and it also reduced pancreatic inflammation through NLRP3 pathway. 【Conclusion】 This experiment confirmed the real existence of ferroptosis, a form of cell death, in AP, and revealed that inhibition of ferroptosis can reduce pancreatic inflammatory damage in AP.

ABSTRACT

【Objective】 To investigate the relationship between the initial serum ammonia level and the risk of ICU and hospital mortalities in critically ill patients without hepatic disease. 【Methods】 A retrospective cohort study was conducted among patients admitted to the eICU Collaborative Research Database (eICU-CRD) for a single admission who had serum ammonia test records within 48 hours of the first ICU admission and had no hepatic disease. The age, sex, ethnicity, Acute Physiologic and Chronic Health Evaluation Ⅳ score (APACHE Ⅳ score), treatment methods, complications, and outcomes were extracted. Univariable and multivariable Logistic regression were used to analyze the relationship between serum ammonia level and the risk of mortality. Interactions were used to analyze whether the relationship between serum ammonia level and the risk of mortality differed in subgroups of APACHE Ⅳ scores, age, sex, and ethnicity; subgroup analyses were made. 【Results】 A total of 1 674 patients were included. The multivariable Logistic regression showed that for every 10 μg/dL increase in ammonia, the risk of ICU death increased by 6.9% (OR=1.069, 95% CI: 1.036-1.104), and the risk of hospital death increased by 4.6% (OR=1.046, 95% CI: 1.017-1.076). The risk of ICU death was 1.7 times greater in patients with initial ammonia level of 49-82 μg/dL than in those with <49 μg/dL (OR=1.700, 95% CI: 1.165-2.482), the risk of ICU death was 2.862 times greater in patients with a level of ≥82 μg/dL compared to those with <49 μg/dL (OR=2.862, 95% CI: 1.792-4.570), and the risk of hospital death was 1.844 times higher in the ≥82 μg/dL group than in the <49 μg/dL group (OR=1.844, 95% CI: 1.213-2.804). There were no significant differences between initial ammonia level and the risk of mortalities in different subgroups of APACHEⅣ scores, age, sex, or ethnicity. 【Conclusion】 In critically ill patients without hepatic disease, elevated initial serum ammonia level after ICU admission is associated with a high risk of ICU and hospital mortality.

ABSTRACT

OBJECTIVE To establish a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the simultaneous determination of bepotastine and hydroxychloroquine concentrations in human breast milk and apply it in clinical practice. METHODS The milk samples (50 μL) were precipitated with 200 μL methanol containing the internal standard (100 ng/mL chloroquine), and the supernatant was taken for analysis after vortexing and centrifugation. The separation was performed on a Waters ACQUITY UPLC HSS T3 column with mobile phase consisted of 0.1% formic acid-10 mmol/L ammonium acetate solution (phase A) and methanol (phase B) at gradient elution of 0.35 mL/min. The injection volume was 2 μL, and the analysis time was 4 min. The detection of the analytes was performed by electrospray ionization in positive mode by multiple reaction monitoring with the transition of m/z 388.9→201.9 (bepotastine), m/z 336.3→247.1 (hydroxychloroquine), and m/z 320.2→247.2 (chloroquine). The established LC-MS/MS method was researched in methodology and used to determine the drug concentrations in the breast milk of 1 case of lactating patient. RESULTS The linear range of bepotastine was 2-200 ng/mL( r=0.999), and hydroxychloroquine was 50-1 000 ng/mL (r=0.998). The intra-assay and inter-assay precisions were both ≤15%, and the accuracy, extraction recovery, matrix effect, and stability all met the acceptance criteria for bioanalytical method validation. The concentration result of bepotastine and hydroxychloroquine in the breast milk of the lactating patient showed, after 2 h and 14 h, the concentrations of bepotastine in the breast milk of the patient were 34.95 ng/mL and 5.72 ng/mL; those of hydroxychloroquine were 211.92 ng/mL and 104.18 ng/mL, respectively. The relative infant doses were 1.83% and 0.56%, respectively. CONCLUSIONS The established method is simple, rapid, and sensitive. It is suitable for simultaneous determination of bepotastine and hydroxychloroquine concentrations in human milk and can provide reference for safe drug use during lactation.

ABSTRACT

Objective:To analyze the predictive value of von Willebrand factor (vWF) for venous thromboembolism (VTE) of patients in intensive care unit (ICU) by using propensity score matching (PSM).Methods:Patients admitted to ICU of the Second Affiliated Hospital of Kunming Medical University from December 2020 to June 2022 who stayed in ICU for ≥72 hours and underwent daily bedside vascular ultrasound screening were included. Baseline data such as age, gender, primary disease, and chronic comorbidities were collected. Coagulation indexes before admission to ICU and 24 hours and 48 hours after ICU admission were collected, including prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), international normalized ratio (INR), fibrinogen (Fib), fibrin monomer (FM), vWF, D-dimer, antithrombin Ⅲ (ATⅢ), etc. Patients were divided into VTE group and non-VTE group according to whether they had VTE or not [diagnosis of VTE: patients underwent daily ultrasound screening of bedside blood vessels (both upper and lower limbs, visceral veins), and those suspected of having thrombosis were confirmed by ultrasonographer or pulmonary angiography]. Using PSM analysis method, the VTE group was used as the benchmark to conduct 1 : 1 matching of age, whether there was malignant tumor, whether there was infection, whether there was diabetes, and coagulation indicators before admission to ICU. Finally, the cases with balanced covariates between the two groups were obtained. The risk factors of VTE were analyzed by multivariate Logistic regression analysis. Receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive value of vWF in the occurrence of VTE in critically ill patients.Results:A total of 120 patients were enrolled, of which 18 (15.0%) were diagnosed with VTE within 72 hours after admission to ICU, and 102 (85.0%) were not found to have thrombus in ICU. Before PSM, there were significant differences in age, gender, proportion of malignant tumor and infection, and coagulation indexes between VTE group and non-VTE group. After PSM, 14 pairs were successfully matched, and the unbalanced covariables between the two groups reached equilibrium. Multivariate Logistic regression analysis showed that vWF was an independent risk factor for VTE at 48 hours after ICU admission in critically ill patients [odds ratio ( OR) = 1.165, 95% confidence interval (95% CI) was 1.000-1.025, P = 0.004]. ROC curve analysis showed that the area under the ROC curve (AUC) of vWF at 48 hours after ICU admission for predicting VTE was 0.782, 95% CI was 0.618-0.945, P = 0.007. When the optimal cut-off value was 312.12%, the sensitivity was 67.7% and the specificity was 93.0%. Conclusion:Dynamic monitoring of vWF is helpful to predict the occurrence of VTE in ICU patients, and vWF at 48 hours after ICU admission has certain value in predicting the occurrence of VTE.

ABSTRACT

Diabetic ulcer(DU) is a chronic and refractory ulcer which often occurs in the foot or lower limbs. It is a diabetic complication with high morbidity and mortality. The pathogenesis of DU is complex, and the therapies(such as debridement, flap transplantation, and application of antibiotics) are also complex and have long cycles. DU patients suffer from great economic and psychological pressure while enduring pain. Therefore, it is particularly important to promote rapid wound healing, reduce disability and mortality, protect limb function, and improve the quality of life of DU patients. By reviewing the relevant literatures, we have found that autophagy can remove DU wound pathogens, reduce wound inflammation, and accelerate ulcer wound healing and tissue repair. The main autophagy-related factors microtubule-binding light chain protein 3(LC3), autophagy-specific gene Beclin-1, and ubiquitin-binding protein p62 mediate autophagy. The traditional Chinese medicine(TCM) treatment of DU mitigates clinical symptoms, accelerates ulcer wound healing, reduces ulcer recurrence, and delays further deterioration of DU. Furthermore, under the guidance of syndrome differentiation and treatment and the overall concept, TCM treatment harmonizes yin and yang, ameliorates TCM syndrome, and treats underlying diseases, thereby curing DU from the root. Therefore, this article reviews the role of autophagy and major related factors LC3, Beclin-1, and p62 in the healing of DU wounds and the intervention of TCM, aiming to provide reference for the clinical treatment of DU wounds and subsequent in-depth studies.

ABSTRACT

Diabetic ulcer(DU) is one of the common complications of diabetes often occurring in the peripheral blood vessels of lower limbs or feet with a certain degree of damage. It has high morbidity and mortality, a long treatment cycle, and high cost. DU is often clinically manifested as skin ulcers or infections in the lower limbs or feet. In severe cases, it can ulcerate to the surface of tendons, bones or joint capsules, and even bone marrow. Without timely and correct treatment, most of the patients will have ulceration and blackening of the extremities. These patients will not be able to preserve the affected limbs through conservative treatment, and amputation must be performed. The etiology and pathogenesis of DU patients with the above condition are complex, which involves blood circulation interruption of DU wound, poor nutrition supply, and failure in discharge of metabolic waste. Relevant studies have also confirmed that promoting DU wound angiogenesis and restoring blood supply can effectively delay the occurrence and development of wound ulcers and provide nutritional support for wound healing, which is of great significance in the treatment of DU. There are many factors related to angiogenesis, including pro-angiogenic factors and anti-angiogenic factors. The dynamic balance between them plays a key role in angiogenesis. Meanwhile, previous studies have also confirmed that traditional Chinese medicine can enhance pro-angiogenic factors and down-regulate anti-angiogenic factors to promote angiogenesis. In addition, many experts and scholars have proposed that traditional Chinese medicine regulation of DU wound angiogenesis in the treatment of DU has broad prospects. Therefore, by consulting a large number of studies available, this paper expounded on the role of angiogenesis in DU wound and summarized the research advance in traditional Chinese medicine intervention in promoting the expression of angiogenic factors [vascular endothelial growth factor(VEGF), fibroblast growth factor(FGF), and angiopoietin(Ang)] which played a major role in promoting wound angiogenesis in the treatment of DU to provide ideas for further research and new methods for clinical treatment of DU.

ABSTRACT

Objective: To investigate the pathological features and the clinicopathological significance of TERT detection in those tumors that were difficult to diagnosis. Methods: A total of 93 cases of fibroepithelial tumors without definite diagnosis were collected from the Affiliated Hospital of Qigndao University between 2013 and 2021. The clinical details such as patients' age and tumor size were collected. All slides were re-reviewed and the pathologic parameters, including stromal cellularity, stromal cell atypia, stromal cell mitoses, and stromal overgrowth were re-interpreted. Sanger sequencing was used to detect TERT promoter status, and immunohistochemistry was performed to detect TERT protein expression. The relationship between TERT promoter mutation as well as protein expression levels and the clinicopathological parameters were also analyzed. Results: The patients' ages ranged from 30 to 71 years (mean of 46 years); the tumor size ranged from 1.2 to 8.0 cm (mean 3.8 cm). These tumors showed the following morphologic features: leafy structures in the background of fibroadenoma, or moderately to severely abundant stromal cells. The interpretations of tumor border status were ambiguous in some cases. The incidence of TERT promoter mutation was high in patients of age≥50 years, tumor size≥4 cm, and stromal overgrowth at ×4 or ×10 objective, and these clinicopathologic features were in favor of diagnosis of phyllodes tumors. TERT protein expression levels was not associated with the above clinicopathologic parameters and its promoter mutation status. Conclusions: The diagnostic difficulty for the breast fibroepithelial tumors is due to the difficulty in recognition of the leafy structures or in those cases with abundant stromal cells. A comprehensive evaluation combined with morphologic characteristics and molecular parameters such as TERT promoter may be helpful for the correct diagnosis and better evaluating recurrence risk.

ABSTRACT

Objective: To explore the clinical characteristics of various types of infected pancreatic necrosis(IPN) and the prognosis of different treatment methods in the imaging classification of IPN proposed. Methods: The clinical data of 126 patients with IPN admitted to the Department of Pancreatic and Biliary Surgery, the First Affiliated Hospital of Harbin Medical University from December 2018 to December 2021 were analyzed retrospectively. There were 70 males(55.6%) and 56 females(44.4%), with age(M(IQR)) of 44(17)years (range: 12 to 87 years). There were 67 cases(53.2%) of severe acute pancreatitis and 59 cases (46.8%) of moderately severe acute pancreatitis. All cases were based on the diagnostic criteria of IPN. All cases were divided into Type Ⅰ(central IPN)(n=21), Type Ⅱ(peripheral IPN)(n=23), Type Ⅲ(mixed IPN)(n=74) and Type Ⅳ(isolated IPN)(n=8) according to the different sites of infection and necrosis on CT.According to different treatment strategies,they were divided into Step-up group(n=109) and Step-jump group(n=17). The clinical indicators and prognosis of each group were observed and analyzed by ANOVA,t-test,χ2 test or Fisher exact test,respectively. Results: There was no significant difference in mortality, complication rate and complication grade in each type of IPN(all P>0.05). Compared with other types of patients, the length of stay (69(40)days vs. 19(19)days) and hospitalization expenses(323 000(419 000)yuan vs. 60 000(78 000)yuan) were significantly increased in Type Ⅳ IPN(Z=-4.041, -3.972; both P<0.01). The incidence of postoperative residual infection of Type Ⅳ IPN was significantly higher than that of other types (χ2=16.350,P<0.01). There was no significant difference in the mortality of patients with different types of IPN between different treatment groups. The length of stay and hospitalization expenses of patients in the Step-up group were significantly less than those in the Step-jump group(19(20)days vs. 33(35)days, Z=-2.052, P=0.040;59 000(80 000)yuan vs. 122 000(109 000)yuan,Z=-2.317,P=0.020). Among the patients in Type Ⅳ IPN, the hospitalization expenses of Step-up group was significantly higher than that of Step-jump group(330 000(578 000)yuan vs. 141 000 yuan,Z=-2.000,P=0.046). The incidence of postoperative residual infection of Step-up group(17.4%(19/109)) was significantly lower than that of Step-jump group(10/17)(χ2=11.980, P=0.001). Conclusions: Type Ⅳ IPN is more serious than the other three types. It causes longer length of stay and more hospitalization expenses. The step-up approach is safe and effective in the treatment of IPN. However, for infected lesions which are deep in place,difficult to reach by conventional drainage methods, or mainly exhibit "dry necrosis", choosing the step-jump approach is a more positive choice.
