Objective To explore the expression levels of NOD-like receptor thermal protein domain-asso-ciated protein 3(NLRP3)and interleukin-6(IL-6)in children with bronchial asthma combined with pulmona-ry infection and its relationship with prognosis.Methods A sample of 150 children with bronchial asthma combined with pulmonary infection hospitalized in Nanjing University Medical College Teaching Hospital,North Jiangsu People's Hospital from January 2021 to December 2022 were prospectively enrolled as observa-tion group,All children were followed up for one year.Another 164 healthy children underwent health check-ups were concurrently selected as control group.According to the prognosis,the children in the observation group were divided into good prognosis groups(n=92)and poor prognosis groups(n=58).Serum IL-6 and NLRP3 expression levels were detected in all participants,and receiver operating characteristic(ROC)curve was plotted to evaluate the value of IL-6 and NLRP3 in predicting the poor prognosis in children with bronchi-al asthma combined with pulmonary infection.Results Serum IL-6 and NLRP3 expression levels in the obser-vation group were significantly higher than those in the control group(P＜0.05).Serum IL-6 and NLRP3 ex-pression levels in the poor prognosis group were higher than those in the good prognosis group(P＜0.05).The results of ROC curve analysis showed that the area under the curve of IL-6 alone for predicting the poor prognosis of children with asthma combined with pulmonary infection was 0.772,with a sensitivity of 79.3％and a specificity of 73.9％.The area under the curve(AUC)of NLRP3 alone for predicting the poor prognosis of children with asthma combined with pulmonary infection was 0.735,with a sensitivity of 55.2％and a spe-cificity of 88.0％.The AUC of the combination of IL-6 and NLRP3 for predicting poor prognosis in children with asthma combined with pulmonary infection was 0.851,which was higher than those of IL-6 and NLRP 3 alone for predicting poor prognosis in children(Z=1.563,2.003,P=0.059,0.045),and the sensitivity was 82.8％and specificity was 75.0％,with high predictive value.Conclusion The expression levels of serum IL-6 and NLRP3 is abnormally up-regulated in children with bronchial asthma combined with pulmonary infec-tion,and the two could serve as predictive indicators for poor prognosis.

Objective To investigate the effects and potential mechanisms of Marsdeniae Tenacissimae Caulis(Tongguanteng)injection and extract in human osteosarcoma cells proliferation,migration,invasion,and apoptosis.Methods MNNG/HOS,Saos-2 osteosarcoma cells,and normal bone marrow mesenchymal stem cells(BMSC)were cultured in vitro.Cells were incubated with different concentrations of Tongguanteng injection and Tongguanteng extract(40,60,80 mg/mL).Cell proliferation was evaluated by CCK-8 assay and plate colony formation assay.Cell migration and invasion were evaluated by scratch assay and Transwell assay.Cell apoptosis was evaluated by Hoechst33342 staining and Annexin-V/PI double staining assay.Bax,Bcl-2 and Caspase-3 mRNA expression were detected using RT-qPCR.The protein expressions of JAK1,p-JAK1,STAT3,p-STAT3 and MMP9 were detected by Western blot.Results Compared with the control group,both Tongguanteng injection and extract significantly decreased the survival rate of MNNG/HOS and Saos-2 cells,inhibited cell clone formation,migration,and invasion,induced cell apoptosis(P<0.05,P<0.01),promoted Bax mRNA and protein expression,inhibited Bcl-2 mRNA and protein expression,and up-regulated Caspase-3 mRNA and Cleaved Caspase-3 protein expression.Tongguanteng injection could significantly down-regulate the expressions of p-JAK1,p-STAT3 and MMP9 protein expression in Saos-2 cells(P<0.05,P<0.01).Conclusion Both Tongguanteng injection and Tongguanteng extract can significantly inhibit proliferation,migration and invasion of human osteosarcoma MNNG/HOS and Saos-2 cells,and induce apoptosis,with no significant difference in anti-tumor effect.The mechanism may be related to the inhibition of the activation of JAK1/STAT3 signaling pathway.

Objective·To analyze the epidemiological characteristics of risk factors for cardiovascular diseases and malignant tumors based on the Shanghai community elderly cohort.Methods·The study subjects were selected from the Shanghai community elderly cohort established from February to August 2019,with a total of 17 948 people.The study subjects were divided into 4 groups according to self-reported presence or absence of tumors and/or cardiovascular diseases during the baseline survey:tumor-free and non-cardiovascular disease group,single cardiovascular disease group,single tumor group and tumor cardiovascular disease co-occurrence group.The differences among the four groups of subjects were collected and compared in terms of demographic characteristics and physiological indicators,daily living habits(smoking,drinking tea,drinking coffee,drinking carbonated drink,drinking alcohol,sedentary time,physical activity level and sleep quality),past medical history,psychological status(depression and anxiety)and dietary compliance.Results·Among the study subjects,60.1%of tumor patients were complicated with cardiovascular diseases.The differences among the four groups of subjects in age,gender,educational level,pre-retirement occupation,waist circumference,hip circumference and body mass index were statistically significant(all P<0.05).Compared with the tumor-free and non-cardiovascular disease group,the single cardiovascular disease group,single tumor group and tumor cardiovascular disease co-occurrence group all exhibited lower proportions of smoking and high physical activity levels(all P<0.05),and higher proportion of sedentary time exceeding 4 h/d and poor sleep quality(all P<0.05);the proportion of subjects with past medical histories including hyperlipidemia,peripheral vascular disease,endocrine system disease,respiratory system disease,urinary system disease and digestive system disease of the single cardiovascular disease group and the tumor cardiovascular disease co-occurrence group was higher(all P<0.05),and the proportion of subjects with depression and anxiety was also higher(all P<0.05).Furthermore,compared with the tumor-free and non-cardiovascular disease group,the single cardiovascular disease group had lower compliance rates of poultry,fish,fruit and liquid milk(all P<0.05).Among the four groups,only the compliance rate of vegetable intake exceeded 50%,while the compliance rates of poultry,fish,fruit,liquid milk and tubers were all below 20%.Conclusion·In the elderly population of Shanghai communities,over half of malignant tumor patients are concomitant with cardiovascular diseases.Unhealthy daily habits are prevalent among those with cardiovascular diseases,tumors and tumor-cardiovascular disease co-occurrence.The intake of many foods in the elderly of the community do not reach the levels recommended by Chinese Dietary Guidelines.

Objective·To compare the physical activities of stroke population and non-stroke population based on the baseline survey of the elderly population cohort in Shanghai communities,and explore the participation in different types of physical activities of stroke population.Methods·The subjects were screened from Shanghai Community Elderly Cohort constructed from February to August,2019 according to the admission criteria.The subjects were divided into non-stroke group and stroke group according to whether they had reported a history of stroke by themselves,and the two groups were matched 2 to 1 by controlling age and sex with propensity score matching.The baseline characteristics of the two groups were collected,and the physical activities related to sports,transportation and housework in the last week were investigated with the International Physical Activity Questionnaire(IPAQ).Pittsburgh Sleep Quality Index(PSQ1)was used to evaluate the sleep quality of the subjects.Generalized Anxiety Disorder(GAD-7)and Patient Health Questionnaire-9(PHQ-9)were used to evaluate anxiety and depression of the subjects,respectively.The above characteristics were compared between the stroke group and non-stroke group,and the participation of different types of physical activities were compared between the two groups by multivariate Logistic regression model.Results·Among the 17 948 people included,there were 993(5.5％)in the stroke group and 16 955(94.5％)in the non-stroke group.After propensity score matching,there were 1 984 people(66.7％)in the non-stroke group and 992 people(33.3％)in the stroke group.There were significant differences in education level,pre-retirement occupation,waist circumference,body mass index,sleep status,anxiety symptoms,depression symptoms and disease history between the two groups(all P＜0.05).In terms of physical activities,the female stroke group had shorter daily moderate exercises time,fewer riding and walking days in one week,and shorter daily riding time,compared with the non-stroke people,with statistical significance(all P＜0.05).Compared with the non-stroke people,the weekly housework days and daily housework time in the male and female stroke groups were lower than those in the non-stroke group,while the daily sedentary time was longer,with statistical significance(all P=0.000).In terms of physical activity level,the proportions of men and women in the stroke group who reached medium or high level were lower than those in the non-stroke group,and the differences were statistically significant(all P=0.000).After adjusting for gender,age,occupation,anxiety symptoms,history of hyperlipidemia,history of atrial fibrillation,history of chronic gastritis and history of hip fracture by multivariate Logistic regression model,the level of vigorous exercise participation in the stroke group was lower,the proportions of no housework in the last week and sedentary time greater than 180 min per day were higher,and the proportion at medium and high activity levels was lower(all P＜0.05).Conclusion·The frequency and duration of housework participation and the physical activity level of elderly people with a history of stroke in Shanghai communities are at a lower level than those without stroke,and they also have a longer sedentary time.

Objective:To compare the clinical efficacy of endoscopic resection and laparoscopic surgery in the treatment of gastric gastrointestinal stromal tumor (GIST) with a maximum diameter of 2 to 5 cm, and to analyze the influence of factors such as tumor surface, growth pattern and lesion origin on the choice of resection method, so as to provide a safer and more effective treatment for patients with gastric GIST.Methods:From January 2012 to November 2019, at the First Affiliated Hospital of Zhengzhou University, the clinical data of 301 patients with gastric GIST who underwent endoscopic resection (137 cases in the endoscopic resection group) or laparoscopic surgery (164 cases in the laparoscopic surgery group) were retrospectively analyzed, including age, gender, whether there was depression on the tumor surface (the local subsidence depth of the mucosa on the tumor surface was >5 mm), whether the tumor surface was irregular (non-hemispherical or non-elliptical tumor surface), whether there was combined ulcer, location, shape, origin of the lesion, growth pattern (intralumina growth or combined intraluminal and extraluminal growth), risk classification (very low risk, low risk, medium risk, high risk), whether the tumor was en bloc resection, operation time, whether bleeding or not, fasting time, indwelling time of gastric tube, time of hospitalization, time of postoperative hospital stay, postoperative complications and follow-up. Independent sample t test, chi-square test or Fisher′s exact test and Wilcoxon rank sum test were used for statistical analysis. Results:Among the 137 patients with gastric GIST in the endoscopic resection group, 85 cases (62.0%) underwent endoscopic submucosal dissection, 9 cases (6.6%) underwent endoscopic submucosal excavation, 42 cases (30.7%) underwent endoscopic full-thickness resection, and 1 case (0.7%) underwent submucosal tunnel endoscopic resection. There were no significant differences in gender, age, lesion location, tumor size, and risk classification between the endoscopic resection group and the laparoscopic surgery group (all P>0.05). The tumor surface was depressed, with ulcer or irregular in 1, 49, 26, and 2 cases of patients with gastric GIST of very low risk, low risk, medium risk and high risk, respectively. There was statistically significant difference in the proportion of depression, irregularity and ulcer on the tumor surface at different risk levels ( Z=-2.55, P=0.011). The complete tumor resection rate of the endoscopic resection group was lower than that of the laparoscopic surgery group (86.1%, 118/137 vs. 100.0%, 164/164), and the difference was statistically significant ( χ2=24.28, P<0.001). However the operation time, fasting time, the indwelling time of gastric tube, time of hospitalization, and the time of postoperative hospital stay of the endoscopic resection group were shorter than those of the laparoscopic surgery group, and the total hospitalization cost was lower than that of the laparoscopic surgery group (90.0 min (62.5 min, 150.0 min) vs. 119.5 min, (80.0 min, 154.2 min); 3 d (3 d, 4 d) vs. 5 d (4 d, 7 d); 3 d (2 d, 4 d) vs. 4 d (2 d, 6 d); 11 d (10 d, 14 d) vs. 16 d (12 d, 20 d); 7 d (6 d, 9 d) vs. 9 d (7 d, 11 d); (38 211.6±10 221.0) yuan vs. (59 926.1±17 786.1) yuan), and the differences were statistically significant ( Z=-2.46, -7.12, -4.44, -6.89 and -5.92, t=-13.24; all P<0.05). The incidence of postoperative abdominal pain and other severe postoperative complications (including shock, respiratory failure, pulmonary embolism, gastroparesis, etc.) of the endoscopic resection group were all lower than those of the laparoscopic surgery group (16.8%, 23/137 vs. 27.4%, 45/164; 0.7%, 1/137 vs. 4.9%, 8/164), and the differences were statistically significant ( χ2=4.84, Fisher′s exact test, P=0.028 and 0.043). There were no significant differences in the incidence of intraoperative bleeding, postoperative bleeding, fever and perforation between the two groups (all P>0.05). The incidence of operation-related complications of lesions with intraluminal growth and originating from muscularis propria in the endoscopic resection group were lower than those of the laparoscopic surgery group (19.5%, 25/128 vs. 32.6%, 45/138; 12.6%, 12/95 vs. 31.4%, 37/118), and the differences were statistically significant ( χ2=5.86 and 10.42, P=0.016 and 0.001). There was no significant difference in the postoperative tumor recurrent rate between the endoscopic resection group and the laparoscopic surgery group (0, 0/137 vs. 2.4%, 4/164; Fisher’s exact test, P=0.129). Conclusions:Endoscopic treatment is safe and effective for gastric GIST with a maximum diameter of 2 to 5 cm, which is superior to laparoscopic surgery. However, laparoscopic surgery is recommended for tumor with depressed, ulcerative, or irregular surface and combined intraluminal and extraluminal growth.

Isocitrate dehydrogenase (IDH) is an essential metabolic enzyme in the tricarboxylic acid cycle (TAC). The high mutation frequency of the IDH gene plays a complicated role in gliomas. In addition to affecting gliomas directly, mutations in IDH can also alter their immune microenvironment and can change immune-cell function in direct and indirect ways. IDH mutations mediate immune-cell infiltration and function by modulating immune-checkpoint gene expression and chemokine secretion. In addition, IDH mutation-derived D2-hydroxyglutarate can be absorbed by surrounding immune cells, also affecting their functioning. In this review, we summarize current knowledge about the effects of IDH mutations as well as other gene mutations on the immune microenvironment of gliomas. We also describe recent preclinical and clinical data related to IDH-mutant inhibitors for the treatment of gliomas. Finally, we discuss different types of immunotherapy and the immunotherapeutic potential of IDH mutations in gliomas.

Cleft lip and/or palate (CLP) are the most common craniofacial malformations in humans. Speech problems often persist even after cleft repair, such that follow-up articulation training is usually required. However, the neural mechanism behind effective articulation training remains largely unknown. We used fMRI to investigate the differences in brain activation, functional connectivity, and effective connectivity across CLP patients with and without articulation training and matched normal participants. We found that training promoted task-related brain activation among the articulation-related brain networks, as well as the global attributes and nodal efficiency in the functional-connectivity-based graph of the network. Our results reveal the neural correlates of effective articulation training in CLP patients, and this could contribute to the future improvement of the post-repair articulation training program.

Objective:To explore the relationship between rs2010963, rs3025039 and rs699947 gene polymorphism of vascular endothelial growth factor(VEGF) gene and bronchopulmonary dysplasia(BPD) in Mongolian premature infants.Methods:A case-control design was used to collect 50 cases of Mongolian premature infants who were hospitalized at the Affiliated Hospital of Inner Mongolia Medical University and diagnosed with BPD from January 2016 to December 2020 as the observation group, while 56 cases of non-BPD premature infants of the same nationality and time period were selected as the control group.Using PCR method to detect the genotype and allele distribution of the VEGF gene rs2010963, rs3025039 and rs699947 locus.Combining clinical data to analyze whether the above gene loci were related to the onset of premature infants with Mongolian BPD in our area.Results:Through genetic testing, it was found that CC, CA and AA genotypes can be detected at the rs699947 site of VEGF gene in premature infants in both the observation group and the control group.The frequencies of the three genotypes in the observation group were 16.0%, 24.0%, and 60.0%, respectively; the frequency of the C allele was 28.0%, the frequency of the A allele was 72.0%, and the frequency of the three genotypes in the control group was 32.1.%, 32.1% and 35.7%, respectively.The frequency of C allele was 48.2%, the frequency of G allele was 51.8%, and the allele and genotype frequencies of this locus between the observation group and the control group were significant differences from those of the control group( P<0.05). Conclusion:The polymorphism of VEGF gene rs699947 locus is associated with the occurrence and development of BPD in Mongolian premature infants, and allele A may be a susceptible factor.

Data of 55 cases of gastric neuroendocrine neoplasms (G-NENS) with diameter ≤12 mm in the First Affiliated Hospital of Zhengzhou University from August 2014 to August 2019 were retrospectively analyzed. According to the methods of endoscopic resection, the patients were divided into two groups: the endoscopic mucosal resection with a cap (EMR-C) group (35 cases) and the endoscopic submucosal dissection (ESD) group (20 cases). The results showed that the success rates of operation, the whole resection rates and the complete resection rates were all 100.0% in the two groups. Compared with the ESD group, the EMR-C group had a shorter median operation time (12.00 min VS 28.35 min, P<0.001), less mean hospitalization costs (21 165.19 yuan VS 28 400.35 yuan, P=0.004), and a similar overall incidence of complications [2.86% (1/35) VS 0, P=1.000]. By March 2020, the recurrence rate of EMR-C group and ESD group were 28.6% (10/35) and 15.0% (3/20), respectively, without significant difference ( P=0.418). It is suggested that for G-NENS with diameter ≤12 mm, without muscular invasion, lymph node metastasis or distant metastasis, EMR-C and ESD are both safe and effective, but EMR-C has more advantages in terms of operation time and hospitalization costs.

Objective:To study the effects of conservative treatment versus percutaneous interventional treatment(PCI)on symptoms and prognosis of chronic coronary syndrome patients aged over 75 years with fractional flow reserve(FFR)in the grey zone(0.75≤FFR≤0.80).Methods:A total of 96 coronary heart disease(CHD)patients aged over 75 years undergone FFR examination in our hospital from January 2011 to December 2017 were retrospectively selected.All patients showed stenosis of 50%-90% in at least one main coronary artery and had FFR values within the range of 0.75-0.80(0.75≤FFR≤0.80). According to the treatment, patients were divided into the optimized medication group(OMT group, n=35)and the PCI group(n=61). The degree of angina alleviation assessed by the Seattle Angina Questionnaire(SAQ)and the incidence of major adverse cardiovascular endpoints(death, myocardial infarction, stroke, and repeated revascularization)were recorded during the one-year follow-up after treatment.Results:There was no significant difference in baseline data including age, gender and comorbidities between the OMT and PCI groups( P>0.05). The incidence of previous myocardial infarction, and the basal level of low-density lipoprotein cholesterol(LDL-C)were higher in the PCI group than in the OMT group( P<0.05). One-year follow-up showed that there was no significant difference between the OMT and PCI groups in the score of SAQ(77.6 ± 19.5 vs. 83.1 ± 22.8, P>0.05)and the incidence of composite MACEs(11.4% or 4 / 35 vs. 9.8% or 6/61, P>0.05). However, the incidence of repeated target vessel revascularization was lower in the PCI group than in the OMT group(1.6% or 1 case vs. 5.8% or 2 cases, P<0.05). Conclusions:In elderly CHD patients aged over 75 years with FFR values between 0.75-0.8 in the grey zone, optimal medication treatment has similar effects as the PCI on symptom alleviation, and no significant increase in composite MACEs is found at one-year follow-up.
