ABSTRACT

The development of broad-spectrum antivirals against human coronaviruses (HCoVs) is critical to combat the current coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its variants, as well as future outbreaks of emerging CoVs. We have previously identified a polyethylene glycol-conjugated (PEGylated) lipopeptide, EK1C4, with potent pan-CoV fusion inhibitory activity. However, PEG linkers in peptide or protein drugs may reduce stability or induce anti-PEG antibodies in vivo. Therefore, we herein report the design and synthesis of a series of dePEGylated lipopeptide-based pan-CoV fusion inhibitors featuring the replacement of the PEG linker with amino acids in the heptad repeat 2 C-terminal fragment (HR2-CF) of HCoV-OC43. Among these lipopeptides, EKL1C showed the most potent inhibitory activity against infection by SARS-CoV-2 and its spike (S) mutants, as well as other HCoVs and some bat SARS-related coronaviruses (SARSr-CoVs) tested. The dePEGylated lipopeptide EKL1C exhibited significantly stronger resistance to proteolytic enzymes, better metabolic stability in mouse serum, higher thermostability than the PEGylated lipopeptide EK1C4, suggesting that EKL1C could be further developed as a candidate prophylactic and therapeutic for COVID-19 and other coronavirus diseases.

ABSTRACT

Anti-CD19 chimeric antigen receptor (CAR) T cell therapy has shown impressive efficacy in treating B-cell malignancies. A single-center phase I dose-escalation study was conducted to evaluate the safety and efficacy of T cells transduced with CBM.CD19 CAR, a second-generation anti-CD19 CAR bearing 4-1BB costimulatory molecule, for the treatment of patients with refractory diffuse large B-cell lymphoma (DLBCL). Ten heavily treated patients with refractory DLBCL were given CBM.CD19 CAR-T cell (C-CAR011) treatment. The overall response rate was 20% and 50% at 4 and 12 weeks after the infusion of C-CAR011, respectively, and the disease control rate was 60% at 12 weeks after infusion. Treatment-emergent adverse events occurred in all patients. The incidence of cytokine release syndrome in all grades and grade ⩾ 3 was 90% and 0, respectively, which is consistent with the safety profile of axicabtagene ciloleucel and tisagenlecleucel. Neurotoxicity or other dose-limiting toxicities was not observed in any dose cohort of C-CAR011 therapy. Antitumor efficacy was apparent across dose cohorts. Therefore, C-CAR011 is a safe and effective therapeutic option for Chinese patients with refractory DLBCL, and further large-scale clinical trials are warranted.

ABSTRACT

Radiotherapy uses high-energy X-rays or other particles to destroy cancer cells and medical practitioners have used this approach extensively for cancer treatment (Hachadorian et al., 2020). However, it is accompanied by risks because it seriously harms normal cells while killing cancer cells. The side effects can lower cancer patients' quality of life and are very unpredictable due to individual differences (Bentzen, 2006). Therefore, it is essential to assess a patient's body damage after radiotherapy to formulate an individualized recovery treatment plan. Exhaled volatile organic compounds (VOCs) can be changed by radiotherapy and thus used for medical diagnosis (Vaks et al., 2012). During treatment, high-energy X-rays can induce apoptosis; meanwhile, cell membranes are damaged due to lipid peroxidation, converting unsaturated fatty acids into volatile metabolites (Losada-Barreiro and Bravo-Díaz, 2017). At the same time, radiotherapy oxidizes water, resulting in reactive oxygen species (ROS) that can increase the epithelial permeability of pulmonary alveoli, enabling the respiratory system to exhale volatile metabolites (Davidovich et al., 2013; Popa et al., 2020). These exhaled VOCs can be used to monitor body damage caused by radiotherapy.

ABSTRACT

The morbidity and mortality of hematological tumors have shown a rising tendency in recent years and become one of the major diseases which affect public health. The nutritional and inflammation status of the body has been proved to play an important role in the occurrence, development and prognosis of the blood system disease. The prognostic nutritional index (PNI) is an important index to reflect the nutritional and inflammation status of the body, and it can be calculated by serum albumin level and peripheral blood lymphocyte count. A large number of studies have reported that PNI can effectively predict the prognosis of several hematological tumors, including lymphoma. In this review, the prognostic value of PNI in patients with lymphoma was summarized briefly.

ABSTRACT

@#Objective    To compare the postoperative chylothorax outcomes of robot-assisted thoracic surgery (RATS) and video-assisted thoracoscopic surgery (VATS), analyze the risk factors for postoperative chylothorax after minimally invasive radical lung cancer resection and explore possible prevention and control measures. Methods    Between June 2012 and September 2020, 1 083 patients underwent minimally invasive pulmonary lobectomy and systematic lymph node dissection in our hospital, including 578 males and 505 females with an average age of 60.6±9.4 years. Patients were divided into two groups according to the operation methods: a RATS group (499 patients) and a VATS group (584 patients). After propensity score matching, 434 patients were included in each group (868 patients in total). Chylothorax and other perioperative indicators were compared between the two groups. Univariate and multivariate logistic regression analyses were performed to identify risk factors for postoperative chylothorax. Results    Overall, 24 patients were diagnosed with chylothorax after surgery. Compared with the VATS group, the rate of chylothorax was higher (3.9% vs. 1.6%, P=0.038), the groups and numbers of dissected lymph nodes were more (both P<0.001), and the intraoperative blood loss was significantly less (P<0.001) in the RATS group. There was no statistical difference in the postoperative hospital stay (P=0.256) or chest tube drainage time (P=0.504) between the two groups. Univariate analysis showed that gender (P=0.021), operation approach (P=0.045), smoking (P=0.001) and the groups of dissected lymph nodes (P<0.001) were significantly associated with the development of chylothorax. Multivariate analysis showed that smoking [OR=4.344, 95%CI (1.149, 16.417), P=0.030] and the groups of dissected lymph nodes [OR=1.680, 95%CI (1.221, 2.311), P=0.001] were the independent risk factors for postoperative chylothorax. Conclusion    Compared with the VATS, the rate of chylothorax after RATS is higher with more dissected lymph nodes and less blood loss. The incidence of chylothorax after minimally invasive radical lung cancer resection is higher in the patients with increased dissected lymph node groups and smoking history.

ABSTRACT

Objective@#To evaluate temporal trend in food supply among pilot schools involved in the National Nutrition Improvement Program for Rural Compulsory Education Students (NNIPRCES).@*Methods@#Ten percent of pilot schools were randomly selected and asked to report the information on food supplies. Daily intake of energy, carbohydrates and protein for each student were calculated and compared with the reference value in Nutrition Guidelines of School Meals (WS/T 554-2017).@*Results@#Energy and protein supply increased among those pilot schools. The supply of energy increased from 1 566.5 kcal in 2012 to 1 927.4 kcal in 2017, protein increased from 49.0 g to 61.0 g. The energy ratio of fat increased from 31.9% to 34.9%, while energy ratio of carbohydrate decreased significantly (F=83.38, 128.36, 20.27 and 17.28, all P<0.05). The proportion of reasonable energy supply from carbohydrate and fat in 2017 were 17.5% and 26.8%, respectively.@*Conclusion@#The supply of energy and macronutrients in the pilot areas were unreasonable, more measures including dietary guide and monitoring need to be adopted to improve students nutrition status among rural areas.

ABSTRACT

Objective@#To evaluate snack consumption and the influencing factors associated with student participation in the Nutrition Improvement Program, and to provide a scientific basis for improving the program.@*Methods@#Among the 50 monitoring counties that implemented the Compulsory Education Student Nutrition Improvement Program, two primary schools and two junior schools were randomly selected according to different food supply patterns (i.e., school, company, and mix). This study randomly selected one or two classes from each grade, which ranged from grade 3 to grade 9. A questionnaire, which addressed snack consumption and choice, was distributed to 27 374 students.@*Results@#The findings revealed that 14.0% of students from poor rural areas in central and western regions consumed snacks two or more times per day, and 21.6% of students spent 3 yuan or more on snacks each day. The top three choices of snacks included fruit and vegetables (50.6%), biscuits and bread (50.1%), and puffed food (40.0%). Students who had mothers who worked outside the home, parents who worked outside the home, who consumed corporate meals, and who had access to a small shop on campus were more likely to consume snacks one or more times per day(OR=1.35,1.19,1.11,1.51,P<0.05).@*Conclusion@#The phenomenon of snack consumption among primary and middle school students from poor rural areas in central and western regions is common, and the selection of unhealthy snacks was identified as a problem. A health education system with comprehensive support and guidance from individuals, families, schools, and society should be established to guide students to opt for healthier snacks.

ABSTRACT

Background@#and Purpose The present study aimed to compare the efficacy and tolerability of different blood pressure (BP)-lowering strategies. @*Methods@#Randomized controlled trials that compared various antihypertensive treatments and stroke outcomes were included. Eligible trials were categorized into three scenarios: single or combination antihypertensive agents against placebos; single or combination agents against other agents; and different BP-lowering targets. The primary efficacy outcome was the risk reduction pertaining to strokes. The tolerability outcome was the withdrawal of drugs, owing to drug-related side effects (PROSPERO registration number CRD42018118454 [20/12/2018]). @*Results@#The present study included 93 trials (average follow-up duration, 3.3 years). In the pairwise analysis, angiotensin-converting enzyme inhibitors (ACEis) and beta-blockers (BBs) were inferior to calcium channel blockers (CCBs) (odds ratio [OR], 1.123; 95% confidence interval [CI], 1.008 to 1.252) (OR, 1.261; 95% CI, 1.116 to 1.425) for stroke prevention, BB was inferior to angiotensin II receptor blockers (ARB) (OR, 1.361; 95% CI, 1.142 to 1.622), and diuretics were superior to ACEi (OR, 0.871; 95% CI, 0.771 to 0.984). The combination of ACEi+CCB was superior to ACEi+diuretic (OR, 0.892; 95% CI, 0.823 to 0.966). The network meta-analysis confirmed that diuretics were superior to BB (OR, 1.34; 95% CI, 1.11 to 1.58), ACEi+diuretic (OR, 1.47; 95% CI, 1.02 to 2.08), BB+CCB (OR, 2.05; 95% CI, 1.05 to 3.79), and renin inhibitors (OR, 1.87; 95% CI, 1.25 to 2.75) for stroke prevention. Regarding the tolerability profile, the pairwise analysis revealed that ACEi was inferior to CCB and less tolerable, compared to the other treatments. @*Conclusions@#Monotherapy using diuretics, CCB, or ARB, and their combinations could be employed as first-line treatments for stroke prevention in terms of efficacy and tolerability.

ABSTRACT

@#Objective    To compare the effect on postoperative immune function between da Vinci robot-assisted thoracoscopic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) , and to provide clinical support for more effective surgical procedures. Methods    A total of 90 patients undergoing radical resection of pulmonary carcinoma in our hospital from June to November 2019 were included. There were 49 males and 41 females with an average age of 62.67 (37-84) years. Among them, 50 patients underwent da Vinci robot-assisted thoracoscopic surgery (a RATS group) and 40 patients underwent video-assisted thoracoscopic surgery (a VATS group). The perioperative indexes as well as postoperative inflammatory factors and immune level effects between the two groups were compared. Results    Compared with the VATS, RATS could significantly shorten the operation time and decrease intraoperative blood loss (P<0.05). RATS also effectively reduced the increase of postoperative inflammatory factor level (P<0.05). But there was no significant difference in postoperative immune function between the RATS group and the VATS group (P>0.05). Conclusion    RATS is superior to VATS in the treatment of non-small cell lung cancer in perioperative indicators and inflammatory factors.

ABSTRACT

@#Objective    To explore the factors that affect the drainage time of da Vinci robot lung cancer surgery, to analyze the coping strategies, and to provide a basis for shortening the drainage time of patients after surgery and speeding up the patients' recovery. Methods    The clinical data of 131 patients who underwent da Vinci robot lung cancer surgery at the Department of Thoracic Surgery, General Hospital of Northern Theater Command from January 2019 to October 2019 were retrospectively analyzed. Among them, 68 were males and 63 were females, with an average age of 59.84±9.66 years. According to the postoperative thoracic drainage time, the patients were divided into two groups including a group A (drainage time≤ 5 days) and a group B (drainage time >5 days). Univariate analysis and logistic multivariate regression analysis were used to analyze the factors that may affect postoperative drainage time, and the correlation between different influencing factors and thoracic drainage time after da Vinci robot lung cancer surgery. Results    Logistic multivariate analysis showed that age≥60 years (P=0.014), diabetes mellitus (P=0.035), operation time≥130 min (P=0.018), number of lymph node dissections≥15 (P=0.002), and preoperative albumin<38.45 g/L (P=0.010) were independent factors affecting the drainage time of da Vinci robot lung cancer surgery. Conclusion    For elderly patients with diabetes mellitus during the perioperative period, blood glucose should be actively controlled, reasonable surgical strategies should be formulated to ensure the safety and effectiveness of the operation, while reducing intraoperative damage and shortening the operation time. After the operation, patients should be guided to strengthen active coughing, expectoration and lung expansion. Thereby it can shorten drainage time and speed up the recovery of patients after operation.

ABSTRACT

Drug-associated reward memories are conducive to intense craving and often trigger relapse. Simvastatin has been shown to regulate lipids that are involved in memory formation but its influence on other cognitive processes is elusive. Here, we used a mass spectrometry-based lipidomic method to evaluate the impact of simvastatin on the mouse brain in a cocaine-induced reinstatement paradigm. We found that simvastatin blocked the reinstatement of cocaine-induced conditioned place preference (CPP) without affecting CPP acquisition. Specifically, only simvastatin administered during extinction prevented cocaine-primed reinstatement. Global lipidome analysis showed that the nucleus accumbens was the region with the greatest degree of change caused by simvastatin. The metabolism of fatty-acids, phospholipids, and triacylglycerol was profoundly affected. Simvastatin reversed most of the effects on phospholipids induced by cocaine. The correlation matrix showed that cocaine and simvastatin significantly reshaped the lipid metabolic pathways in specific brain regions. Furthermore, simvastatin almost reversed all changes in the fatty acyl profile and unsaturation caused by cocaine. In summary, pre-extinction treatment with simvastatin facilitates cocaine extinction and prevents cocaine relapse with brain lipidome remodeling.

ABSTRACT

Objective:To analyze the influence of Corona Virus Disease 2019(COVID-19) epidemic on inpatient disease spectrum, treatment methods and outcomes in pediatric intensive care unit(PICU)in non-epidemic areas.Methods:The clinical data of children admitted to PICU at Shengjing Hospital of China Medical University from February 1, 2019 to May 30, 2019(group Ⅰ)and from February 1, 2020 to May 30, 2020(group Ⅱ)were collected retrospectively.We analyzed the spectrum changes of infectious and non-infectious diseases, visiting time, as well as compared the diseases of various systems and accidental injuries, and the use of important treatment methods, all-cause mortality.Results:There were 339 cases in group Ⅰ and 208 cases in group Ⅱ.The total number of patients in group Ⅱ decreased by 38.6% compared with group Ⅰ.There was no significant difference in pediatric multiple organ dysfunction score (P-MODS)( P=0.894)between two groups within 24 hours after admission, but pediatric logistic organ dysfunction score (PELOD)-2 in group Ⅱ[1(0, 3)] was higher than that in group Ⅰ[1(0, 2)] within 24 hours after admission, with statistical difference( P=0.012). The length of hospital stay in group Ⅱ was longer than that in group Ⅰ, but there was no statistical difference.The length of hospital stay in shock group, accidental injury and poisoning group were 6(5.25, 8.25)days and 9(6, 16)days, respectively, with statistical differences( P=0.048, P=0.001). Compared with group Ⅰ, the number and ratio of infectious diseases(pneumonia, aseptic encephalitis and sepsis)in group Ⅱ decreased significantly[176(52.1%)to 93(44.5%), P=0.095]. Neuromuscular diseases: aseptic encephalitis decreased from 13.2% to 7.2%; non-traumatic intracranial hemorrhage increased from 0.9% to 3.8%, with statistical difference( P=0.028, P=0.017). Compared with group Ⅰ, the number of invasive interventional therapy cases in group Ⅱ decreased significantly, among which non-invasive ventilator, plasma exchange and fiberoptic bronchoscope decreased by at least 50%, but there was no significant difference between two groups.The average time from onset to visit was 7(4, 12)days in group Ⅰ and 3(1, 6)days in group Ⅱ, with statistical difference( P=0.002). There were 16 hospital deaths in group Ⅰ, with a mortality rate of 4.7%, and 7 hospital deaths in group Ⅱ, with a mortality rate of 3.4%.There was no significant difference in the total mortality and the mortality of the main diseases causing death. Conclusion:The epidemic situation of Corona Virus Disease 2019 led to characteristic changes in disease spectrum of children admitted to PICU, and infectious diseases were obviously reduced.Non-infectious diseases such as trauma and poisoning were still the main causes of critically ill children.During the epidemic period, there was no obvious change in treatment, PICU admission time and all-cause mortality rate of critically ill children in non-epidemic areas, thus it could be seen that the epidemic did not have adverse effects on treatment, referral, and prognosis of critically ill children.

ABSTRACT

Objective:To explore the clinical characteristics and early diagnosis of cerebral infarction in critically ill children.Methods:The clinical data of the children who were diagnosed with cerebral infarction in PICU at Shengjing Hospital of China Medical University from January 2013 to September 2019 were analyzed retrospectively.Results:There were 27 children in this study, including 15 males and 12 females.The age of onset ranged from 1 month to 13 years old, with age of 3.0(0.7, 8.0) years old.Among 27 cases, there were ten cases of infection(37.0%), six cases of trauma(22.2%), three cases of congenital heart disease (11.1%), two cases of cerebrovascular disease (7.4%), one case of diabetic ketoacidosis(3.7%) and two cases of autoimmune factors(7.4%). The cause was unknown in three cases(11.1%). The main clinical manifestations were convulsion in 11 cases(40.7%), status convulsion in five cases(18.6%), limb dysfunction in four cases(14.8%), disturbance of consciousness in fvie cases(18.5%) and facial paralysis in four cases(14.8%). Among 27 cases, mechanical ventilation was performed in 12 cases (44.4%). The levels of D-dimer in all children were increased in varying degrees.After improvement and discharge, two children developed secondary epileptic sequelae.Head CT examination was performed in 20 cases, of which 11 cases showed definite cerebral infarction, eight cases of temporal lobe lesions and three cases of basal ganglia lesions.MRI+ MRA examination of the head in 27 cases showed that there were cerebral infarction and the infarct area large.Conclusion:The high incidence age of cerebral infarction in critically ill children is infantile.The most common diseases are infection, trauma, congenital heart disease, and the first clinical manifestations are convulsion and coma.Imaging examination showed that a high proportion of children had large area infarction, and the diagnostic effect of MRI is better than that of CT.D-dimer may be helpful for early clinical diagnosis.

ABSTRACT

Objective:To investigate the physical activity level and sedentary time of school-age children with bronchial asthma (asthma).Methods:Asthmatic children aged 6 to 17 years old who used Chinese Children′s Asthma Action Plan on smartphones from March to May 2021 were included in the study.International Physical Activity Questionnaire (IPAQ) was employed to assess exercise level, and Health Behavior in School-Aged Children (HBSC) was employed to evaluate sedentary behavior.The Childhood Asthma Control Test (C-ACT), and the Asthma Control Test (ACT) were employed to assess asthma control status.Clinical information was collected, including age, gender, body mass index (BMI), respiratory symptoms after exercise and adherence to medication.Results:A total of 265 valid questionnaires were collected, with a median age of 9.4 (7.5, 11.6) years old.The rate of ACT/C-ACT score ≥ 20 was 74.0% (196 cases). There were 52 cases with high, 110 cases with medium and 103 cases with low activity levels.There was no significant correlation between activity level and gender, BMI, regular drug use or educational level of parents ( P>0.05). The number of children with sedentary time ≥2 hours was 204 on weekdays and 233 on weekends, respectively, and the number on weekends was significantly higher (87.9% vs.77.0%, χ2=10.967, P=0.001). There were 160 cases (60.4%) with respiratory symptoms after exercise, with the most common symptoms including cough(72 cases), wheezing(53 cases), dyspnea(43 cases), chest pain(16 cases) and chest tightness(15 cases). Despite the symptoms, 79.6%(211 cases)of all children had the subjective intention to participate in physical activities.The incidence of post-exercise symptoms in children with ACT/C-ACT scores ≥20 was significantly lower than that in children with ACT/C-ACT≤19 (37.8% vs.72.5%, χ2=10.967, P<0.001). Conclusions:Most school-age children with bronchial asthma had low to moderate levels of physical activity, and the sedentary time is long.Children with poorly controlled asthma are more likely to develop respiratory symptoms after exercise.Standardized and individualized exercise prescriptions should be further formulated to guide children with asthma to carry out reaso-nable physical exercise.

ABSTRACT

Objective:To know the exercise status of asthmatic in school-age, and to identify possible influen-cing factors.Methods:School-age children with a firm diagnosis of asthma were continuously included in Asthma Clinic of Allergy Department, Children′s Hospital Affiliated to Capital Medical University from January 2016 to January 2017.Patients who complain any symptoms during or after exercise with or without exercise limitation were assigned to the abnormal exercise group (ANE), and children who stated no symptoms and exercise limitation were defined as normal exercise group (NE), correspondingly.These data include age, gender, length of recurrent wheezing history, duration of treatment with inhaled corticosteroids (ICS), asthma control status, body mass index (BMI), pulmonary function parameters by spirometry and plethysmography that were collected and analyzed.Results:A total of 194 cases were included: 135 cases (69.6%) were well controlled, 39 cases (20.1%) were partially controlled, and 20 cases (10.3%) were uncontrolled.Totally, 95 cases (49.0%) were distributed in ANE group, while 99 cases (51.0%) were in NE group.Meanwhile, 111 patients (57.2%) had normal BMI, 32 patients (16.5%) were overweight, and 51 patients (26.3%) were obese.In the Logistic regression model of all cases, the worse asthma control level (partially controlled OR=4.77, 95% CI: 2.07-11.00, P<0.001, uncontrolled OR=10.02, 95% CI: 2.70-37.22, P=0.001) and higher BMI ( OR=1.15, 95% CI: 1.06-1.25, P=0.001) were closely associated with the significantly increased risk of exercise abnormality.Among the patients with normal BMI, ANE group had more cases with hyperinflation than normal exercise group (43.8% vs.19.0%, P=0.005). Conclusions:The results suggested that poor asthma control status and overweight/obesity are risk factors for exercise limitation, and excessive lung inflation may also affect exercise in children with asthma.
