Acute lung injury （ALI） refers to the rapid onset of dyspnea, hypoxemia, and diffuse alveolar damage induced by various direct and indirect injurious factors, representing one of the clinically common diseases with a high mortality rate. However, there is currently a lack of specific therapeutic interventions targeting their underlying pathological mechanisms. Western medical treatment primarily relies on supportive care, and the existing pharmacological agents for ALI are predominantly corticosteroids, which, while efficacious, often accompany severe adverse effects. Recent research has revealed that numerous active components in Traditional Chinese Medicine （TCM） exhibit remarkable efficacy in the prevention and treatment of ALI, providing new insights into the therapeutic approaches for ALI. In this article, the pathological mechanisms of ALI and the roles and mechanisms of active components from TCM in the prevention and treatment of ALI were reviewed, aiming to provide a theoretical basis for the development of new drugs for the prevention and treatment of ALI.

The classification of lung tumor with the help of computer-aided diagnosis system is very important for the early diagnosis and treatment of malignant lung tumors.

This paper summarizes the commonly used research algorithms for lung tumor classification, introduces concepts and technologies of machine learning, radiomics, deep learning and multiple data fusion, points out the existing problems and difficulties in the field of lung tumor classification, and looks forward to the development prospect and future research direction of lung tumor classification.

OBJECTIVE：To improve the quality standard of Taraxaci Herba ，and to evaluate the quality of T. officinale from different origins. METHODS ：Based on the provisions of the 2020 edition of Chinese Pharmacopoeia （part Ⅰ）under the item “Taraxaci Herba ”，the method of content determination was added for the detection of water-soluble extracts （hot extraction method）and alcohol-soluble extracts （hot extraction method ），total flavonoids ，chlorogenic acid ，caffeic acid ，cichoric acid and isochlorogenic acid A. HPLC fingerprint was established by using 42 batches of T. officinale from 8 producing areas as object ，and principal component analysis was performed on the basis of above results. RESULTS ：The contents of alcohol-soluble extracts in 42 batches of T. officinale were 15.30％-30.40％，and those of water-soluble extracts were 27.59％-38.96％. The concentration of total flavonoids（UV spectrophotometry ），chlorogenic acid ，caffeic acid ，cichoric acid and isochlorogenic acid A （HPLC method ）were 0.016-0.096，0.003-0.196，0.004-0.117，0.025-1.578，0.002-0.152 mg/mL，respectively （all R2＞0.999）；RSDs of precision ， stability and repeatability tests were all lower than 2.00％（n＝6）；average sample recovery were 98.97％-103.53％，and RSDs were 1.19％-1.58％. The contents of total flavonoids ，chlorogenic acid ，caffeic acid ，cichoric acid and isochlorogenic acid A were 0.734％ -3.700％ ，0.004％ -0.123％ ，0.006％ - 0.087％ ，0.073％ -1.499％ ，0.005％ -0.109％ respectively in 42 batches of T. officinale. For 42 batches of T. officinale samples in HPLC fingerprint ，RSDs of the relative retention time of the common peak were 0-0.94％，and RSDs of the relative peak area were 0-125.57％. Among them ，the similarity of 39 batches of samples was all higher than 0.900. Results of principal component analysis showed that the quality of T. officinale from Shaanxi province was better，followed by medicinal materials from Hebei province. CONCLUSIONS ：Tentatively，the contents of alcohol-soluble extract，water-soluble extract ，total flavonoids ，chlorogenic acid ，caffeic acid ，cichoric acid and isochlorogenic acid A shall not be less than 17.0％，27.0％，1.383％，0.024％，0.021％，0.450％，0.021％ for Taraxaci Herba. In addition to the low content of caffeic acid in T. officinale from Shaanxi province ，the other indexes were better ；the content of caffeic acid in T. officinale from Hebei province was higher than that from Shaanxi province ，and other indicators were slightly lower than that from Shaanxi province. The quality of comprehensive evaluation of T. officinale from other origins was relatively poor ，and the quality of different batches of medicinal materials from the same origin was unstable.

Objective: To explore the molecular and genetic mechanism of transcription factor GATA-6 in nonsyndromic conotruncal defect (CTD) in order to provide evidence for early prevention and inheritance consultation of CTD. Methods: A total of 32 cases of patients with nonsyndromic CTD and 100 healthy individuals were enrolled in the study.A total of 7 exons and bilateral partial intron-exon boundaries of GATA-6 were amplified by means of polymerase chain reaction (PCR). The PCR products were purified and directly sequenced by using an ABI Genetic Analyzer 3100 Automatic DNA sequence equipment.The acquired GATA-6 gene sequence was compared with standard gene sequence published in National Center for Biotechnology Information database, as well as the healthy control group to observe the GATA-6 gene mutations.The mutations were introduced into pcDNA3.1(+ ) by site-directed mutagenesis PCR on the basis of pcDNA3.1(+ )-GATA-6 in order to generate the GATA6-G245R mutant constructs.Wild type GATA-6, GATA-6-G245R and atrial natriuretic factor-luciferase(ANF-luciferase) were cotransfected into HEK 293T cells in vitro, and the CMV-LacZ were cotransfected as internal reference.Luciferase and galactosidase activity were measured by using luminometer 24 h after transfection and detected in the downstream ANF-luciferase reporter gene. Results: A heterozygous missense mutation in the GATA-6 gene was identified in a patient with double outlets of the right ventricle.The mutation was located in Gly245Arg(G245R) in exon 2 of GATA-6.The mutation of pcDNA3.1(+ )-GATA-6 expression vectors were successfully constructed.Through the detection of luciferase reporter gene activity, it was found that GATA-6-G245R and wild-type GATA-6 decreased by 41.3%, and the comparison between them was statistically significant (P<0.001). Conclusions Transcription factor GATA-6 gene mutation is associated with the occurrence of nonsyndromic CTD.Transcription factor GATA-6 gene may be susceptible gene in human nonsyndromic CTD.

The lung is the second most common site of neuroendocrine tumors (NETs). Typical and atypical carcinoids are low-grade NETs of the lung. These rare tumors have received little attention and education is needed for treating physicians. The article describes the classifcation of lung NETs, the epidemiology and pathological characteristics. When lung NETs are diagnosed at an early stage, surgical intervention is often curative. For advanced lung NETs patients, different treatment methods including chemotherapy, somatostatin analogs, m-TOR inhibition, peptide receptor radioligand therapy, and biologic systemic therapy are discussed. The conclusions are generally extrapolated from the outcome of extra-pulmonary carcinoids. Prospective randomized well-designed trials are urgently needed to inform current recommendations on systemic treatment.

Objective To study l-arginine aerosolized inhalation's protective effect on pulmonary ventilation of the pulmonary-arterial-hypertension patients during the early stage after pulmonary lobectomy,and its preventive effect on reducing postoperative complications.Methods 54 cases of pulmonary lobectomy patients with preoperative plumonary arterial hypertension were divided into two groups randomly-Group A was given L-arginine aerosolized inhalation within 4 h after the operation;Group B was given the same dose of aerosolized inhalation of physiological saline as contrast(other postoperative medication being the same with Group A).Compare the two groups of patients in terms of oxygenation index(PaO2/FiO2),alveolararterial oxygen difference(PA-aO2),nitric oxide(NO) concentration,ultrasonic cardiogram,mechanical ventilation duration,ICU duration,occurances of hemodvnamic disturbance and arrhythmia,and differences in postoperative hospital stay.Results The oxgenation index and the content of NO in plasma of Group A were higher than that of Group B(P ＜0.001);the alveolar-arterial oxygen difference and the postoperative pulmonary arterial pressure detected by UCG of Group A were lower than that of Group B(P ＜ 0.001);the postoperative mechanical ventilation duration,ICU duration,occurances of hemodynamic disturbance and arrhythmia of Group A were all lower than that of Croup B(P ＜ 0.05).Conclusion The postoperative l-arginine aerosolized inhalation during the early stage after pulmonary lobectomy has positive effect on the lung protection of the pulmonary-arterial-hypertension patients and it can reduce the perioperative complications and postoperative hospital stay of such patients.

Objective The mechanism of the lymph node metastasis in lung adenocarcinoma is unknown.The characteristic of the N1 and N2 lymph nodes metastasis are different.We explore the relationship between the N1 lymph node metastasis and clinicopathological factors in lung adenocarcinoma patients.Methods Data of 126 patients who had received lobectomy and systematic lymph node dissection were retrospectively analyzed.Chi-square test and Fisher exact method was used in univariate analysis,logistic regression was performed to analyze the multivariate analysis.Critical value was calculate in ROC.All the methods executed in software SPSS 19.0.Results After analyzed the N1 lymph node metastasis and clinicopathological factors,sex (P =0.016),diameter of tumor (P =0.001),pleural invasion (P =0.008),micropapillary pattern (P =0.028),solid pattern (P =0.047) has statistical significance in univariate analysis.Logistic regression analysis reveal diameter of tumor,micropapillary pattern and solid pattern were independent risk factors for N1 lymph nodes.CEA level (P =0.004),cancer embolus (P =0.029),micropapillary pattern (P =0.018),affect the groups (number of metastasis station) of the metastasis lymph nodes.Logistic regression analysis find CEA and micropapillary pattern were independent risk factors,which might lead multiple groups lymph nodes metastasis.There is only one factor could impact the location of the N1 lymph node metastasis,which is micropapillary pattern (P =0.027).Conclusion Via ROC results,there are three factors affect the N1 lymph nodes metastasis:purity of micropapillary pattern more than 27.5％,purity of solid pattern more than 15％,diameter of tumor larger than 3.0 cm.If a lung adenocarcinoma patient who was in early stage has one or more than one factors,we suggest chemotherapy followed the surgery.Higher CEA level or higher content of micropapillary pattern much more groups lymph nodes metastasis might appear,so radiotherapy and other method should be considered to added on.High content of micropapillary pattern maybe imply cancer cell has already invaded extra pulmonary lymph nodes.

Objective To understand the relationship between GATA -4,-5,-6 gene mutations and con-genital heart disease(CHD),and to provide grounds for early prevention and genetic counseling of children with CHD. Methods GATA -4,-5,-6 coding regions exons and the flanking intron sequences in 1 98 CHD patients were screened,including 66 cases of the ventricular septal defects,84 cases of the atrial septal defects,and 48 cases of the nonsyndromic conotruncal heart defects patients.A total of 300 healthy subjects were selected as controls.The acquired sequences were aligned with which those publicized in GenBank by the aid of program BLAST.All exons and bilateral partial intron -exon boundaries of GATA -4,-5,-6 genes were amplified by the polymerase chain reaction (PCR). The PCR products were purified and directly sequenced by automatic DNA sequence equipment.The acquired GATA -4,-5,-6 gene sequences were compared with GenBank standard gene sequences with the aid of program BLAST. Results A heterozygous missense mutation in the GATA -4 gene was identified in a ventricular septal defect patient and a persistent truncus arteriosus patient.The mutation was located in c.799G >A(p.V267M)in exon 4 of GATA -4. Multiple aligenment of GATA -4 proteins across species demonstrated that altered amino acid was highly conserved. Transcription factor GATA -5,-6 screening showed no mutations in children with CHD in this study.Conclusions Transcription factor GATA -4 gene mutation may be associated with the occurrence of CHD.Transcription factor GATA -4 gene may be susceptible gene in human CHD.

Objective To compare the clinical effects between uniportal video-assisted thoracic surgery (VATS) and 3-portal VATS lobectomy for patients with lung cancer. Methods Patients were divided into uniportal VATS lobectomy group (n=45) and 3-portal VATS lobectomy group (n=53). The clinical data were compared between two groups, including the oper-ation time, intraoperative blood loss, number of lymph node dissection, length of incision, postoperative extubation time, post-operative pain score and postoperative hospitalization. Results There were no significant differences in intraoperative blood lose (128.75±18.32) mL vs (129.15±17.69) mL, lymph node dissection number (13.33±1.05) vs (13.12±1.38), duration of chest drainage (4.90±0.75)d vs (4.75±0.70)d, duration of hospital stay (7.52±1.16)d vs (7.55±1.10)d and incidence of seri-ous postoperative complications between two groups (P>0.05). The incision length (5.36±0.22)cm vs (7.44±0.35)cm, numeric pain intensity scale including first day(6.47±0.54) vs (6.86±0.52),third day(3.59±0.29) vs (4.05±0.25), and patient satisfac-tion scores (91.03 ± 2.62) vs (88.35 ± 2.97) were significantly better in uniportal VATS group than those of 3-portal VATS group (P<0.05). The operation time (143.81±17.97) min vs(130.11±15.03)min was longer in uniportal VATS group than that of 3-portal VATS group (P < 0.05). Conclusion Uniportal VATS lobectomy is safe and reliable for patients with early-stage lung cancer, which has less surgical injury, slighter pain, and higher satisfaction than 3-portal VATS lobectomy.

Objective To investigate the expression levels and clinical significance of (forkhead box Q1) FOXQ1 and E-cadherin in esophageal squamous cell carcinoma (ESCC). Methods Expression levels of FOXQ1 and E-cadherin were in ESCC tissues (ESCC group, n=42) and adjacent normal esophageal tissues (control group, n=42) were detected using im?munohistochemistry. Correlations of FOXQ1 and E-cadherin expressions with clinical pathological parameters and progno?sis were analyzed between two groups. Results The expression level of FOXQ1 was significantly higher in ESCC group than that in control group(64.29% vs 28.57%,χ2=5.384,P<0.05). The expression level of E-cadherin was significantly lower in ESCC group than that incontrol group(52.38%vs 90.48%,χ2=7.691,P<0.05). There were significant differences in FOXQ1 expressions between different TNM stages and whether lymph node metastasis is involved within ESCC group. There were significant differences in expression of E-cadherin between different tumor differentiation, depth of invasion, TNM stage and whether lymph node metastasis is involved within ESCC group. The expression of FOXQ1 was negatively cor?related with E-cadherin in ESCC (r=-0.412, P<0.05). The 5-year survival rates were significantly lower with high expres?sion of FOXQ1 or with low expression of FOXQ1(18.52%vs 66.67%,χ2=9.737,P<0.05). The 5-year survival rates were significantly higher with high expression of E-cadherinor low expression of E-cadherin(59.09%vs 10.00%,χ2=10.996,P<0.05). A multivariate Cox's proportional hazard regression analysis indicated that high FOXQ1 expression, low E-cadherin expression and lymph node metastasis were independent prognostic factors for ESCC. Conclusion The expression of FOXQ1 and E-cadherin showed a good correlation with ESCC. And examining expressions of both FOXQ1 and E-cadherin in ESCC may have practical values in estimating the prognosis of ESCC and directing future treatment .
