Objective:To investigate the relationship between spread through air spaces(STAS) of peripheral stage ⅠA small adenocarcinoma of the lung(≤2 cm) and related factors such as clinical and CT morphological features, and to construct a nomogram model.Methods:Relevant clinical, pathological and imaging data of patients who underwent lung surgery and were diagnosed as peripheral stage ⅠA small lung adenocarcinoma by postoperative pathology in the Affiliated Hospital of Nantong University from 2017 to 2022 were collected, of which cases that met the inclusion criteria from 2017 to 2021 served as the training group, and those that met the inclusion criteria in 2022 served as the validation group. The independent risk factors for the occurrence of STAS in peripheral stage ⅠA lung small adenocarcinoma were investigated by using univariate analysis and multifactorial logistic regression analysis, based on which a nomogram prediction model was constructed, and the subjects were analyzed by using the receiver operating characteristic curve( ROC), correction model, etc. were used to evaluate the model. Results:A total of 430 patients who met the criteria were included, including 351 patients in the training group(109 STAS-positive and 242 STAS-negative) and 79 patients in the validation group(23 STAS-positive and 56 STAS-negative). Univariate analysis showed that the patients in the two groups showed a significant difference in age(>58 years old), gender, smoking history, tumor location(subpleural, non-subpleural), pleural pull, nodule type, nodule maximal diameter, solid component maximal diameter, consolidation tumor ratio(CTR), lobulation sign, burr sign, bronchial truncation sign, vascular sign(includes thickening and distortion of blood vessels in/around the nodes), satellite lesions, and ground-glass band sign were statistically significant( P<0.05). The results of multifactorial logistic regression analysis showed that CTR( OR=4.98, P<0.001), lobulation sign( OR=4.07, P=0.013), burr sign( OR=3.66, P<0.001), and satellite lesions( OR=3.56, P=0.009) were the independent risk factors for the occurrence of STAS. Applying the above factors to construct the nomogram model and validate the model, the results showed that the ROC curve was plotted by the nomogram prediction model, and the area under the ROC curve( AUC) of the training set was 0.840(sensitivity 0.835, specificity 0.734), and the validation set had an AUC value of 0.852(sensitivity 0.786, specificity 0.783), and the training set and validation set calibration curves have good overlap with the ideal curve. Conclusion:CTR, lobular sign, burr sign, and satellite lesions are independent risk factors for STAS, and the nomogram model constructed in this study has good predictive value.

BACKGROUND:Cardiac hypertrophy is an adaptive response of the heart to physiological and pathological stimuli such as pressure overload.It is of compensatory significance in the early stage,but if the stimulation continues,it can cause cardiomyopathy leading to heart failure.MicroRNAs are involved in the regulation of cardiac hypertrophy.However,the role of miR-20a in pressure overload-induced cardiac hypertrophy has not been reported. OBJECTIVE:To investigate the role of miR-20a in pressure overload-induced cardiac hypertrophy and the underlying mechanisms. METHODS:Transverse aortic constriction was used to induce cardiac hypertrophy in vivo and angiotensin Ⅱ was used to induce H9c2 cell models of cardiac hypertrophy in vitro.MiR-20a was overexpressed in vivo by intramyocardial injection of miR-20a overexpressing adenovirus and in vitro by transfecting miR-20a mimic into H9c2 cells.Cardiac hypertrophy was assessed by measuring heart weight/body weight ratio,cell surface area,and myocardial fibrosis.The expression levels of atrial natriuretic peptide,brain natriuretic peptide,β-myosin heavy chain and miR-20a were detected by real-time fluorescence quantitative PCR.Mitochondrial fission was detected by MitoTracker.The downstream target genes of miR-20a were predicted by RNAhybrid software. RESULTS AND CONCLUSION:(1)The expression level of miR-20a was significantly decreased in both hypertrophic cardiomyocytes and hearts(P<0.05).(2)At the animal level,overexpression of miR-20a significantly inhibited transverse aortic constriction-induced cardiac hypertrophy,including decreasing the upregulated expression level of hypertrophic marker genes(P<0.05),reduced the enlarged heart volume,reducing the increased heart weight/body weight ratio(P<0.01),reducing the increased myocardial cross-sectional area(P<0.05),and attenuating fibrosis(P<0.01).(3)At the cellular level,overexpression of miR-20a significantly inhibited angiotensin Ⅱ-induced cardiomyocyte hypertrophy,including decreasing the upregulated expression levels of atrial natriuretic peptide(P<0.05),brain natriuretic peptide(P<0.01)and β-myosin heavy chain(P<0.05),reducing the increased protein/DNA ratio(P<0.01),and suppressing the increased cell surface area(P<0.05).(4)Overexpression of miR-20a significantly inhibited angiotensin Ⅱ-induced mitochondrial fission(P<0.05).(5)The results of RNAhybrid software analysis showed that miR-20a and the mRNA 3'untranslated region of cAMP-dependent protein kinase inhibitor alpha were well complementary and the predicted binding sites were highly conserved.(6)In conclusion,miR-20a is significantly down-regulated in pressure overload-induced cardiac hypertrophy.Overexpression of miR-20a inhibits cardiac hypertrophy at both the cellular level and animal level and attenuates angiotensin Ⅱ-induced mitochondrial fission.

This paper explored the disease mechanism of autism spectrum disorders (ASD) from the perspectives of “vital activity” and “qi configuration”, and it is believed that “vital activity” represents the internal regulatory mechanisms of the human body, while “qi configuration” represents the ability of the body to communicate and adapt to the external environment. Abnormal genetic factors lead to the extinction of vital activity in children with ASD, resulting in increased susceptibility to ASD. Environmental instability leads to the solitary qi configuration in ASD, triggering and exacerbating the manifestations of ASD on the basis of genetic susceptibility. In addition, epigenetic mechanisms also play an important role in the pathogenesis of ASD. Imbalances in vital activity and disruptions in qi configuration result in failure in qi transformation of zang-fu organs, with abnormal symptoms manifested through the five orifices. It is proposed that the treatment of ASD should aim to achieve a harmonious interaction between “vital activity” and “qi configuration” to accelerate the recovery of affected children.

Daochisan is a pediatric famous classical formula in traditional Chinese medicine(TCM) specializing in clearing the heart, disinhibiting water and enriching Yin, which has been inherited and developed by medical experts of successive generations. The formula can be traced back to Xiaoer Yaozheng Zhijue written by QIAN Yi from Song dynasty, and most of the later-developed Daochisan(Daochitang) is based on this formula with additions and subtractions. So as to promote the literature excavation of this formula, this paper conducts a thorough textual research and analysis of the composition, processing, preparation methods, clinical applications of Daochisan based on a systematic collation of relevant ancient and modern literature in the method of bibliometrics. A total of 127 pieces of data involving 86 antient TCM books were collected. Statistical analysis showed that the drug origin of Daochisan is basically clear, we suggest that Rehmanniae Radix is the root tuber of Rehmannia glutinosa of Scrophulariaceae, Akebiae Caulis is the dry stem of Akebia quinata of Lardizabalaceae, Glycyrrhizae Radix et Rhizoma is the dry root and stem of Glycyrrhiza uralensis of legume, bamboo leaf is the dry leaves of Phyllostachys nigra var. henonis of gramineous plants. Four herbs are recommended to use its raw products. The key information of the dosage and decocting method is supposed to be "4.13 g each of raw Rehmanniae Radix, raw Glycyrrhizae Radix et Rhizoma, Akebiae Caulis, adding 300 mL of water, and then adding 4.13 g of bamboo leaf, decocting together to 150 mL, taking warmly after meal". Daochisan has the effect of clearing the heart and enriching Yin, disinhibiting water and relieving stranguria, and is widely used in treating symptoms such as heart vexed hotness, hydrodipsia and reddish complexion. Modern studies have showed that Daochisan are frequently used in treating oral ulcer, herpetic stomatitis, urinary tract infection, herpes zoster and other diseases. The above research results can provide scientific reference for the future development and research of Daochisan.
