ObjectiveThis study explored the risk factors for malignant risks of pulmonary nodules based on clinical data,constructed an integrated traditional Chinese and Western medicine model for predicting malignant risks of pulmonary nodules, and visualized the prediction results by using a nomogram. MethodsBased on a cross-sectional survey study design,patients with pulmonary nodules who were hospitalized in the Department of Respiratory and Cardiothoracic Surgery of Guangdong Provincial Hospital of Traditional Chinese Medicine from April 2023 to January 2024 were included. The dataset was randomly divided into a training set and a validation set according to 7∶3. In the training set,predictive factors were selected through univariate Logistic regression analysis and Least Absolute Shrinkage and Selection Operator (LASSO) regression analysis,and Logistic regression models were built. The discriminative ability,calibration,and clinical decision-making curves of the Western medicine model and the integrated traditional Chinese and Western medicine prediction model were compared to select the optimal model,which was then visualized in a nomogram. ResultsThis study included a total of 366 patients,and they were divided into a training set (258 cases) and a validation set (108 cases). Seven predictive factors were considered including age,preference for fatty and greasy foods,history of environmental or occupational exposure,Qi deficiency,Yang deficiency,nodule density,and nodule diameter. A Logistic regression model was constructed. A Western medicine model,defined as model1,was created using only age,history of environmental or occupational exposure,nodule density,and nodule diameter as predictive factors. In addition,an integrated traditional Chinese and Western medicine model,defined as model2,was created by adding preference for fatty and greasy foods, Qi deficiency,and Yang deficiency as predictive factors. Model2 demonstrated better predictive performance in both the training and validation sets. Its accuracy in training set was 0.740,with precision of 0.825, recall of 0.829, F1 score of 0.827, the area under the curve (AUC)of 0.865 (95% confidence interval (CI):0.815-0.915), and a Brier score of 0.122. The accuracy in validation set was 0.731, with precision of 0.776, recall of 0.831, F1 score of 0.803, AUC of 0.852 (95%CI:0.776-0.927), and a Brier score of 0.149. The calibration curve and decision-making curve analysis showed that this model exhibited good consistency and clinical utility in prediction. The equation for the malignant probability of pulmonary nodules was defined as p=

Objective:
To investigate the chemical compositions of Maxing Shigan Decoction (麻杏石甘汤, MXSGD) and elucidate its anti-influenza A virus (IAV) mechanism from prediction to validation.
Methods:
Ultra high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was employed to analyze the chemical compositions of MXSGD. Network pharmacology theories were used to screen and identify shared targets of both the potential targets of active ingredients of MXSGD and IAV. A protein-protein interaction (PPI) network was then constructed, followed by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses. The binding stability between core bioactive compounds and key targets was validated by molecular docking and dynamic simulations. A total of 24 BALB/c mice were infected with IAV to build IAV mouse models. After successful modelling, the mouse models were randomly divided into model, MXSGD high-dose (2.8 g/kg), MXSGD low-dose (1.4 g/kg), and oseltamivir (20.14 mg/kg) groups, with an additional normal mice as control group (n = 6 per group). The treatments were administered by gavage daily between 8:00 a.m. and 10:00 a.m. for five consecutive days. Upon completion of the administration, the body weight ratio, lung index, protein content in the bronchoalveolar lavage fluid (BALF), and the levels of inflammatory factors including interleukin (IL)-6 and tumor necrosis factor (TNF)-α in mice were measured to preliminarily analyze the therapeutic efficacy of MXSGD against IAV infection. Furthermore, the expression levels of mechanistic target of rapamycin (mTOR), hypoxia inducible factor (HIF)-1α, and vascular endothelial growth factor (VEGF) proteins in the HIF-1 signaling pathway, which was enriched by network pharmacology, were detected by Western blot.
Results:
A total of 212 chemical components in MXSGD were identified by the UPLC-MS/MS method. These chemical components can be classified into 9 primary categories and 31 secondary categories. After intersecting the chemical component targets with IAV-related targets, a total of 567 potential MXSGD components targeting IAV were identified. The construction of PPI network and the results of both GO and KEGG enrichment analyses revealed that the anti-IAV effects of MXSGD were associated with multiple pathways, including apoptosis, TNF, HIF-1, and IL-17 signaling pathways. The results of molecular docking demonstrated that the binding energies between the core compound 1-methoxyphaseollin and key targets including HIF-1α, mTOR, and VEGF were all lower than – 5.0 kcal/mol. Furthermore, molecular dynamics simulations confirmed the structural stability of the resulting complexes. Animal experiments showed that compared with the normal controls, IAV-infected mice showed significantly reduced body weight ratio, markedly increased lung index, protein content in BALF, and the levels of inflammatory factors such as IL-6 and TNF-α (P < 0.01), thereby causing damage to the lung tissue; consequently, the expression levels of mTOR, HIF-1α, and VEGF proteins in the lung tissues of these mice were significantly elevated (P < 0.01). However, after MXSGD treatment, the mouse models presented a significant increase in body weight ratio, as well as marked decreases in lung index, protein content in BALF, and the levels of inflammatory factors including IL-6 and TNF-α (P < 0.01). Furthermore, the therapy alleviated IAV-induced injuries and significantly downregulated the expression levels of mTOR, HIF-1α, and VEGF proteins in lung tissues (P < 0.01 or P < 0.05).
Conclusion
MXSGD exerts anti-IAV effects through multi-component, multi-target, and multi-pathway synergism. Among them, 1-methoxyphaseollin is identified as a potential key component, which alleviates virus-induced lung injury and inflammatory response via the regulation of HIF-1 signaling pathway, providing experimental evidence for the clinical application of MXSGD.

ObjectiveTo explore the differences in human papillomavirus (HPV) genotype among patients with varying stages of cervical intraepithelial neoplasia (CIN). MethodsThis retrospective study included 113 patients with CIN who were treated at the Third People’s Hospital of Hangzhou from April 2020 to March 2023. The patients were divided into three groups based on the progression of CIN: CIN Ⅰ (n=30), CIN Ⅱ (n=42), and CIN Ⅲ (n=41). The influencing factors of CIN progression were analyzed, and HPV genotyping was performed logistic regression analysis was used to examine relationship between HPV genotypes and the degree of CIN progression, and the interaction between HPV genotypes and CIN progression-related factors were assessed. ResultsHPV genotype analysis revealed that HPV16, HPV58, HPV18, and HPV52 were the most common genotypes among CIN patients. The proportion of negative HPV cases in CIN I patients (53.33%) was significantly higher than that in CIN Ⅱ (33.33%) and CIN Ⅲ (0) patients. The infection rates and multiple infection rates of HPV16, HPV58, HPV18, and HPV52 (3.33%, 3.33%, 0, 0, 0.) were significantly lower in CIN Ⅰ patients compared to CIN Ⅱ (7.14%, 4.76%, 2.38%, 4.76%, 2.38%) and CIN Ⅲ patients (24.39%, 19.51%, 12.20%, 14.63%, 12.20%) (P<0.05). After adjusting for confounding factors, HPV16, HPV18, HPV52, and HPV58 remained significantly associated with the progression of CIN (P<0.05). Having ≥2 sexual partners (OR=3.529, 95%CI: 2.756~6.925, P=0.025), abnormal discharge odor (OR=5.684, 95%CI: 2.439~8.942, P=0.036), contact bleeding (OR=2.679, 95%CI: 1.627~3.192, P=0.018), and chronic cervicitis (OR=3.894, 95%CI: 1.952~4.931, P=0.031) were independent factors influencing the progression of CIN. HPV16, HPV18, HPV52, HPV58 exhibited positive interactions with the number of sexual partners, abnormal discharge odor, contact bleeding, and chronic cervicitis (P<0.05). ConclusionHPV16, HPV58, HPV18, and HPV52 are the most common genotypes of HPV infection in CIN patients, which are positively correlated with the degree of CIN progression. These genotypes are also closely related to factors influencing CIN progression.

ObjectiveTo evaluate the clinical efficacy and safety of Xianqi Qinglong Formula (仙芪青龙方, XQF) in the treatment of cough variant asthma (CVS) patients with lung and kidney deficiency and exuberant wind-induced spasm and tension syndrome. MethodsA randomized, positive-controlled, non-inferiority clinical trial was designed. Totally, 102 CVS patients with lung and kidney deficiency and exuberant wind-induced spasm and tension syndrome were randomly divided into a treatment group (52 cases) and a control group (50 cases). The treatment group was given XQF granules orally, 1 dose per day, 2 bags each time (9.25 g/bag), twice a day, after breakfast and dinner; the control group was given XQF granules placebo orally combined with inhaled fluticasone propionate inhalation aerosol (125 μg each time, twice a day). Both groups were treated for 12 weeks and followed up for 12 weeks, with a total of 24 weeks. The primary outcome was the cough symptom score (including daytime, nighttime and total score), evaluated before treatment (at enrollment), during treatment (after the 6th week of enrollment), at the end of treatment (after the 12th week of enrollment), and at the end of follow-up (after the 24th week of enrollment). The non-inferiority was determined by the lower limit (LCL) of the unilateral 95% confidence interval. The secondary outcomes included cough relief and disappearance, total score of TCM syndrome, cough visual analogue (VAS) score, Leicester Cough Questionnaire (LCQ) score, and lung function indicators including forced expiratory volume in 1 second (FEV1), percentage of predicted forced expiratory volume in 1 second (FEV1%pred), forced vital capacity (FVC), and peak expiratory flow (PEF). Blood routine and liver and kidney function were tested before and after treatment, and the adverse events were recorded. ResultsA total of 101 patients were included in the full analysis set (FAS), including 52 cases in the treatment group and 49 cases in the control group. After treatment, the daytime, nighttime and total cough symptom scores during treatment, at the end of treatment and at the end of follow-up all decreased in both two groups (P<0.01). The unilateral 95% LCL of the total cough symptom scores during treatment, at the end of treatment and at the end of follow-up of the two groups were -0.14, -0.47 and -0.27 (95% LCL all>-0.6). There were no significant differences in the cough relief rate, cough disappearance rate, cough relief days and cough disappearance days between the two groups at each time point (P>0.05). Compared to those before treatment, the TCM syndrome scores and cough VAS scores during treatment, at the end of treatment and at the end of follow-up decreased in both groups, while the LCQ scores increased (P<0.01), but there were no significant differences in FEV1, FEV1%, FVC and PEF before and after treatment (P>0.05). There were no significant differences in TCM syndrome scores, cough VAS scores, LCQ scores, FEV1, FEV1%, FVC, and PEF between the two groups at each time point (P>0.05). No clinically significant abnormal liver and kidney function were found in the two groups before and after treatment. ConclusionXQF is not inferior to fluticasone propionate inhalation aerosol in relieving cough symptoms, reducing cough scores, decreasing the number of cough attack days, and improving the quality of life when treating CVS patients with lung and kidney deficiency and exuberant wind-induced spasms and tension syndrome, and relatively safe.

Objective:To analyze the expression of silent information regulator 2-related enzyme 1 (SIRT1) and its relationship with chondrocyte apoptosis in patients with Kashin-Beck disease (KBD).Methods:Twenty patients with KBD were selected as the KBD group from Guide County, Qinghai Province, and 40 healthy subjects matched by age and sex were selected as the control group. Fasting elbow venous blood of the study subjects was collected, and peripheral blood mRNA levels of SIRT1 and selenoprotein genes [glutathione peroxidase (GPX) 2, GPX3, thioredoxin reductase (TXNRD) 1, TXNRD3, iodothyronine deiodinase Ⅰ (DIO1), and selenophosphate synthetase 2 (SPS2)] were detected by real-time PCR. The correlation between SIRT1 expression and selenoprotein genes in peripheral blood of KBD patients was analyzed by curve fitting method. Meanwhile, normal human chondrocytes cultured in vitro were divided into control group (without any treatment), resveratrol (RES) group (to verify the activation effect of RES on SIRT1), tert-butyl hydroperoxide (tBHP) injury group (oxidative injury model of chondrocyte), and RES protection group (tBHP injury after RES pre protection). The mRNA levels of SIRT1, selenoprotein genes, and apoptosis-related genes [B lymphoblastoma-2 gene (BCL2), BCL2-associated X protein (BAX), nuclear transcription factor κB (NF-κB) p65, and tumor suppressor gene P53] in each group of cells were detected by real-time PCR. Results:In the population study, the peripheral blood SIRT1 mRNA level in the KBD group (1.12 ± 0.38) was lower than that of control group (1.87 ± 0.97), and the difference was statistically significant ( t = 3.31, P = 0.002). According to curve fitting analysis, the mRNA levels of GPX3, TXNRD1, and TXNRD3 in peripheral blood of KBD group increased with the increase of SIRT1 mRNA level ( R2 = 0.48, 0.66, 0.95, P < 0.001). The level of DIO1 mRNA showed a trend of decreased first and then increased with the increase of SIRT1 mRNA level ( R2 = 0.51, P = 0.024). The mRNA levels of GPX2 and SPS2 showed no significant change trend with the increase of SIRT1 mRNA level ( R2 = 0.16, 0.12, P = 0.064, 0.114). In cell studies, compared with the control group (1.00 ± 0.10), the SIRT1 mRNA level in the RES group (1.79 ± 0.07) was higher ( P < 0.05). Compared with tBHP injury group, the RES protection group had higher mRNA levels of selenoprotein genes GPX3, TXNRD1, TXNRD3, and DIO1 ( P < 0.05); the mRNA levels of apoptosis-related genes BAX, P53 and the ratio of BAX/BCL2 were lower, while the mRNA levels of BCL2 and NF-κB p65 were higher ( P < 0.05). Conclusions:KBD patients have low expression of SIRT1. And RES activation of SIRT1 may enhance the antioxidant capacity of chondrocyte by up-regulating the expression of selenoprotein genes, thus inhibiting chondrocyte apoptosis.
