Psychological problems are significant factors that contribute to the occurrence of postoperative complications, reduced quality of life, and prolonged hospital stays. Lung cancer patients who require surgery often experience high psychological stress related to both the disease and the treatment, making them more susceptible to depression and anxiety. Therefore, timely intervention to address these psychological issues is crucial for promoting postoperative recovery and improving patients' quality of life. This paper will review the current status, impact, and interventions for depression and anxiety-related psychological problems in lung cancer surgery patients.

Threatened abortion is a common disease of obstetrics and gynecology and one of the diseases responding specifically to traditional Chinese medicine （TCM）. The China Association of Chinese Medicine organized experts in TCM obstetrics and gynecology， Western medicine obstetrics and gynecology， and pharmacology to deeply discuss the advantages of TCM and integrated Chinese and Western medicine treatment as well as the medication plans for threatened abortion. After discussion， the experts concluded that chromosome， endocrine， and immune abnormalities were the key factors for the occurrence of threatened abortion， and the Qi and blood disorders in thoroughfare and conception vessels were the core pathogenesis. In the treatment of threatened abortion， TCM has advantages in preventing miscarriages， alleviating clinical symptoms and TCM syndromes， relieving anxiety， regulating reproductive endocrine and immune abnormalities， personalized and diversified treatment， enhancing efficiency and reducing toxicity， and preventing the disease before occurrence. The difficulty in diagnosis and treatment of threatened abortion with traditional Chinese and Western medicine lies in identifying the predictors of abortion caused by maternal factors and the treatment of thrombophilia. Recurrent abortion is the breakthrough point of treatment with integrated traditional Chinese and Western medicine. It is urgent to carry out high-quality evidence-based medicine research in the future to improve the modern diagnosis and treatment of threatened abortion with TCM.

Objective:To investigate the reproducibility of whole-heart and volume-targeted balanced steady-state free precession (bSSFP) non-contrast MR coronary angiography (CMRA) for displaying coronary trunks.Methods:From February and September 2021, the whole-heart and volume-targeted CMRA examinations of 58 volunteers were prospectively and consecutively acquired in The First Affiliated Hospital of Fujian Medical University. Each volunteer underwent CMRA twice within a week. The subjective score, vessel-to-myocardium ratio (VMR), vessel-to-fat ratio (VFR), signal-noise ratio (SNR), and coronary corresponding coordinate was analyzed and extracted. Inter-observer, intra-observer and inter-scan consistency were evaluated by intraclass correlation coefficient (ICC), Bland-Altman analysis, Hausdorff Distance (HD), and Dice Similarity Coefficient (DSC).Results:The inter-observer and intra-observer consistencies of subjective scores, VMR, and VFR of the whole-heart and volume-targeted coronary artery images were excellent (ICC>0.76, P<0.001). The inter-scan VFR consistencies of RCA, LM, and LCX of whole-heart coronary scans were moderate (ICC=0.235, 0.264, 0.380, all P<0.05), while the consistencies of the remaining variables were good, (all ICCs>0.49, P<0.001). Bland-Altman method showed that most VMR, VFR, and SNR of two CMRA imaging were within the 95% limits of agreement. Whole-heart CMRA inter-and intra-observer mean HD was 1.79 (1.35, 3.25), 1.68 (1.09, 4.10), mean DSC was 0.96±0.04, 0.97±0.03. Volume-targeted CMRA inter-and intra-observer mean HD were 1.74 (1.63, 3.11), 1.74 (1.63, 1.98), and the mean DSC was 0.91±0.10, 0.95±0.05. The subjective score of raw images of the total artery trunk of volume-targeted CMRA [3.86 (3.68,4.00) vs. 3.80 (3.58,3.96) ], VMR [1.45 (1.27,1.58) vs. 1.22 (1.13,1.41) ], and VFR [7.36 (6.44,8.60) vs. 5.97 (4.97,6.64) ] were better than those of whole-heart CMRA (all P<0.05). The overall subjective score of whole-heart CMRA coronary trunk curved projection reformation was better than volume-targeted CMRA [3.75 (3.57, 3.88) vs. 3.63 (3.44, 3.71)] ( P<0.001). Conclusions:Whole-heart and volume-targeted bSSFP non-contrast CMRA represent good reproducibility and image quality in the main coronary artery of healthy volunteers. Both of the two methods have their advantages and complement each other.

Objective To investigate the expression of miR-372 in the plasma of patients with acute my-eloid leukemia(AML)and the possible mechanism to participate in the development of AML. Methods Real-time quantitative PCR was used to detect the level of miR-372 in plasma. Bioinformatics software predicted the pos-sible target genes of miR-372 and dual luciferase reporter assay was performed to validate the prediction. In HL-60 cells,miR-372 was knocked down,and the effects on cell migration and cloning were detected by scratch test and clone formation. Results The level of miR-372 was significantly up-regulated in the plasma of AML patients. ROC analysis showed that miR-372 could distinguish between AML patients and healthy controls. Dual luciferase report-er assay showed that miR-372 could inhibit the activity of PTEN-3'UTR. Inhibition of miR-372 in HL-60 cells can significantly reduce the cell migration rate and clone formation ability. Conclusion In summary,for the first time,we showed novel data that the level of miR-372 was increased in the plasma of AML patients. By targeting the tumor suppressor gene PTEN,miR-372 may become a potential noninvasive biomarker for the screening and di-agnosis of AML.

AIM To study the therapeutic effects of Neiyi Kangfu Tablets (Trionycis Carapax,Ostreae concha,Rhei Radix et Rhizoma,etc.) on adenomyosis and its possible mechanism of action.METHODS The mouse model for adenomyosis was set up by the pituitary allograft,and received the gavage of Neiyi Kangfu Tablets,Dan'e Fukang Decoction (Salviae miltiorrhizae Radix et Rhizoma,Curcumae Rhizoma,Paeoniae Radix rubra,etc.) and gestrinone,respectively,for three months.Western blot,real-time PCR,IHC were used to measure the expression of GPER-Ras-STAT3 in ectopic endometrium and entopic endometrium.RESULTS High doses of Neiyi Kangfu Tablets could significantly lower GPER protein and gene expression;down-regulate the Ras and STAT3 protein expression;reduce the lesion severity score of ectopic tissue morphology.Its curative effect was better than Dan'e Fukang Decoction and gestrinone.CONCLUSION Neiyi Kangfu Tablets may control the development of ectopic lesions by inhibiting the GPER-Ras-STAT3 pathway activity and weakening the production of estrogen.

Objective: To study the relationship between the development of hepatocellular carcinoma(HCC) and HBV gene characteristics among the HCC patients with hepatitis B virus (HBV) infection. Methods: Some acute and chronic hepatitis B patients were collected as control group and HBV associated HCC patients as HCC group. Serum samples of subjects were tested for HBV serological markers. HBV DNA of those samples had been extracted and nested PCR was used to amplify the sequence of HBV DNA. Furthermore, MEGA 6.0 and Bioedit softwares were used to made phylogenetic trees and analyze the gene mutations. Results: The sequences of S region and BCP/Precore region of HBV were amplified from 86 samples in study group and 39 samples in control group. The prevalence of PreS deletion, A1762T and A1762T/G1764A in HCC group were 39.53%, 74.42% and 72.09% respectively, and in control group were 20.51%, 53.85% and 53.85% respectively. The statistical differences of them were significant. The prevalence of A1762T and A1762T/G1764A in ≥ 50 years group were higher than that of < 50 years group. The prevalence of A1762T, G1764A and A1762T/G1764A of subjects who infected genotype C were higher than those infected genotype B. On the contrary, the prevalence of G1896A of subjects who infected genotype C were lower than that of genotype B. It was found that ≥ 50 years, genotype C and G1896A mutation were independently associated with HCC. The risk for suffer from HCC of ≥50 years group, genotype C group and G1896A group were 9.349, 28.875 and 7.648 times compared with < 50 years group genotype B group and without G1896A mutation group, respectively. Conclusions The population of ≥50 years or genotype C had a higher prevalence of A1762T, A1762T/G1764A, ≥50years、genotype C、G1896A were independently associated with HCC, as compared with the subjects of the control group.

Objective To investigate the relationship between plasma homocysteine (Hcy), Kv1.3 channel and cardiac troponinI (cTnI) in patients with acute ST-segment elevation myocardial infarction (STEMI). Methods According to the level of Hcy, 80 STEMI patients were divided into STEMI with Hhcy group (Hcy > 15 μmol/L, n=41) and control group (STEMI group, Hcy≤15μmol/L, n=39). The Hcy, blood lipid and cTnI were detected with automatic biochemistry analyzer, respectively. Peripheral lymphocytes were isolated by ficoll density gradient centrifugation. Real-time PCR was used to detect mRNA expression of Kv1.3, and Western blot assay was used to detect protein expression of Kv1.3. Results cTnI concentrations were obviously higher in STEMI with Hhcy group than those in STEMI group (μg/L:22.997 ± 5.880 vs. 12.881 ± 6.343;P<0.01). Multiple linear regression analysis showed that age, gender, hypertension, diabetes mellitus, smoking, family history, total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C) and low density lipoprotein-cholesterol (LDL-C) had no obvious influence on Hcy (P>0.05). The relative expression levels of Kv1.3 mRNA and protein were significantly higher in STEMI with Hhcy group (1.35±0.14, 0.85±0.12) than those in STEMI group (1.00 ± 0.07, 0.64 ± 0.05, P<0.05). Moreover, there was a positive relation between Hcy level and the mRNA and proteinexpression of Kv1.3 channel (r=0.299, r=0.542, P<0.05). There was a positive relation between protein expression levels of Kv1.3 channel and cTnI (r=0.644, P<0.05). Conclusion Our results support that Hcy could exacerbate the concentration of cTnI through playing an important role in the Kv1.3 mRNA and protein expression in lymphocytes.

Objective:To establish the cisplatin-resistant human lung adenocarcinoma cell line A549/(DDP) cisplatin and to study the relationship between EHD2 and drug resistance. Methods:DDP-resistant human lung cancer cell line A549/DDP was established by gradual and stepwise dose enhancement. MTT was used to measure drug sensitivity. Western blot and immunofluorescence were used to evaluate expression and subcellular localization of EHD2 and breast cancer resistance protein (BCRP). Results:The DDP-resistant cell line A549/DDP was established, with a resistance index of 7.6. EHD2 and BCRP expressions both increased and were enriched on the cell surface membrane. Conclusion:Both EHD2 and BCRP expressions were enriched on the resistant cell surface membrane, suggesting that EHD2 endocytic protein stabilizes BCRP and is involved in drug resistance.

Objective To investigate the roles of the chemokine receptor CXCR3 and its ligand I-TAC in the pathogenesis of immune thrombocytopenic purpura (ITP).Methods A total of 48 ITP patients were enrolled in this study:30 with newly diagnosed or relapse ITP and 18 in remission after treatment,and 24 healthy volunteers were as controls.IFNγ and I-TAC in plasma were detected by ELISA.The mRNA expression of CXCR3 in the peripheral blood mononuclear cells (PBMNCs) was determined by quantitative RT-PCR.Results The IFNγ level in the plasma of ITP patients before the treatment was obviously increased than those in the remission group and controls[ (71.45 ± 17.62)ng/L vs (36.94 ±14.86 )ng/L and (25.28 ± 12.85 )ng/L,all P ＜ 0.05 ]and those in the remission group was higher than in the controls ( P ＜ 0.05 ).In contrast,there were no statistic differences of the levels of I-TAC among the three groups[ (455.56 ± 144.70 ) ng/L,( 488.24 ± 164.70 ) ng/L and ( 382.97 ± 167.43 ) ng/L,P ＞0.05 ].Both ITP patients before the treatment and remission groups expressed more CXCR3 mRNA [ 6.76(3.03,37.00),1.76 (0.45,14.18 ) vs 0.12 ( 0.04,0.28 ),P ＜ 0.05 ].After effective therapy,CXCR3mRNA expression decreased,while it was still higher than that in the controls.Conclusions Our data demonstrate that Th1 cytokine (IFNγ) dominance is reflected in ITP.Simultaneously,the CXCR3 + cell may play a role in cell-mediated immunity through chemotaxis in ITP.

OBJECTIVE: To observe the clinical treatment effectiveness of clarithromycin for naso-sinusitis after nasopharyngeal carcinoma radiotherapy. METHOD: Twenty-four cases of naso-sinusitis after one year nasopharyngeal carcinoma radiotherapy were treated with the oral clarithromycin of small dosage (250 mg everyday).
