OBJECTIVE: To detect the body surface temperature of the relevant back-shu points in patients with chronic persistent asthma by infrared thermal imaging technology, and observe the specific changes of the body surface temperature of the relevant back-shu points under the condition of lung disease. METHODS: Forty-five patients with chronic persistent asthma (observation group) and 45 healthy subjects (control group) were selected. The body surface temperature of bilateral Feishu (BL 13), Geshu (BL 17), Pishu (BL 20) and Shenshu (BL 23) were measured by BK-MT02A medical infrared thermography. RESULTS: The body surface temperature of bilateral Feishu (BL 13), Geshu (BL 17), Pishu (BL 20) and Shenshu (BL 23) in the observation group was higher than that in the control group (P<0.01, P<0.05). The body surface temperature of bilateral Feishu (BL 13) and Geshu (BL 17) was higher than that of ipsilateral Pishu (BL 20) and Shenshu (BL 23) in the two groups (P<0.01, P<0.05). There was no statistically significant difference in body surface temperature between ipsilateral Feishu (BL 13) and Geshu (BL 17), between ipsilateral Pishu (BL 20) and Shenshu (BL 23) (P>0.05). CONCLUSION The pathological increase of body surface temperature of Feishu (BL 13), Geshu (BL 17), Pishu (BL 20) and Shenshu (BL 23) in patients with chronic persistent asthma indicates that above acupoints have specificity in reflecting lung diseases. The Feishu (BL 13) and Geshu (BL 17), which have significantly increased body surface temperature, not only provide objective basis for the pathological pathogenesis of "deficiency in origin and excess in symptom" in patients with chronic persistent asthma, but also reflect the different expressions of different acupoints on the same meridian for the lung diseases.

21-hydroxylase deficiency(21-OHD) is mainly characterized by cortisol deficiency with or without aldosterone deficiency and hyperandrogenemia.The disease requires lifelong exogenous glucocorticoid/salt supplementation.Excessive doses of exogenous glucocorticoids are often needed to control hyperandrogenemia, but the effect is not satisfactory.Corticotropin releasing factor (CRF) type 1 receptor antagonist can directly block the production of adrenocorticotropin, inhibit the generation of adrenogenic androgen, reduce the dose of glucocorticoid therapy, and thus lower the incidence of adverse reactions.In this article, the current research progress on 21-OHD therapy and CRF1 receptor antagonist was reviewed.

To evaluate e-cigarette vaping-induced respiratory toxicity and the interventional effects of air cleaners. A randomized controlled trial study of toxic vaping by the respiratory tract were conducted at the Key Laboratory of Environmental Medical Engineering, Ministry of Education, the School of Public Health, Southeast University from January to December 2022. 8-week-old male C57BL/6JGpt mice selected with a random number table method were used to establish a vaping-exposure model at different periods (0 d, 3 d, 7 d or 14 d), or exposed to clean air as a control group. Mice were exposed to regular heated vaping (200 ℃) and high-temperature heated vaping (280 ℃). Total lung RNA was extracted from control and e-cigarette exposed mice for transcriptome sequencing analysis. Reactive Oxygen Species (ROS) generation and mitochondrial membrane potential (MMP) were detected by flow cytometry. Total superoxide dismutase (SOD) and superoxide (O^2-) were evaluated using a microplate reader. Real-Time Quantitative PCR (RT-qPCR) was used to detect gene expression. Air filter and ionizer were used to intervene the toxicity of vaping. Data were expressed as (x¯±s), differences between multiple groups were compared using one-way or two-way ANOVA. The results showed that, RNA sequencing assays suggested that the differential genes between the control and vaping exposure groups were significantly enriched in the oxidative stress (Fold Enrichment=3.18) and mitochondrial oxidative phosphorylation (OXPHOS) (Fold Enrichment=5.74) pathways. Both types of heated vaping exposure caused significantly increased the score of alveolitis (F=10.8, P<0.001), increased endogenous ROS generation (F=16.8, P<0.001), decreased MMP (F=13.6, P<0.01), and gene expression of mitochondrial complex I dysfunction. The toxic effects of high-temperature heated vaping were stronger compared to regular heated vaping (F=2.9, P<0.05). The filter demonstrated better protective effects against vaping than the ionizer by reducing pulmonary alveolitis (F=7.4, P<0.01). Air cleaners could partially alleviate oxidative stress and mitochondrial dysfunction. In conclusion, this study demonstrate that vaping brings potential health risks. Air cleaners could partially reverse mitochondrial dysfunction, but cannot completely prevent the toxic effects, effective interventions remain to be investigated.

Objective: To describe the actual efficacy of programmed death-1 (PD-1)/ programmed-death ligand 1 (PD-L1) inhibitors in patients with metastatic non-small cell lung cancer (NSCLC) and explore potential prognostic predictive biomarkers. Methods: Patients with metastatic NSCLC who were treated with PD-1/PD-L1 inhibitors at Cancer Hospital, Chinese Academy of Medical Sciences from January 2016 to December 2019, either as monotherapy or in combination with other agents, were consecutively enrolled into this study. We retrospectively collected the data of demographics, clinical information and pathologic assessment to evaluate the therapeutic efficacy and conduct the survival analysis. Major endpoint of our study is progression-free survival (PFS). Secondary endpoints include objective response rate (ORR), disease control rate (DCR) and overall survival (OS). Results: The ORR of 174 patients who underwent PD-1/PD-L1 inhibitor was 28.7%, and the DCR was 79.3%. Immune-related adverse events (irAEs) occurred in 23 patients (13.2%). Brain metastasis, line of treatment, and treatment patterns were associated with the ORR of metastatic NSCLC patients who underwent immunotherapy (P<0.05). After a median follow-up duration of 18.8 months, the median PFS was 10.5 months (ranged from 1.5 to 40.8 months) while the median OS was not reached. The 2-year survival rate was estimated to be 63.0%. The pathologic type was related with the PFS of metastatic NSCLC patients who underwent immunotherapy (P=0.028). Sex, age, brain metastasis and autoimmune diseases were associated with OS (P<0.05). Analysis of the receptor characteristic curve (ROC) of neutrophil/lymphocyte ratio (NLR) predicting ORR of immunotherapy in metastatic NSCLC showed that the areas under the curve of NLR before immunotherapy (NLR(C0)), NLR after one cycle of immunotherapy (NLR(C1)) and ΔNLR were 0.600, 0.706 and 0.628, respectively. Multivariate logistic regression analysis showed that NLR(C1) was an independent factor of the ORR of metastatic NSCLC patients who underwent immunotherapy (OR=0.161, 95% CI: 0.062-0.422), and the efficacy of combination therapy was better than that of single agent (OR=0.395, 95% CI: 0.174-0.896). The immunotherapy efficacy in patients without brain metastasis was better than those with metastasis (OR=0.291, 95% CI: 0.095-0.887). Multivariate Cox regression analysis showed that NLR(C1) was an independent influencing factor of PFS of metastatic NSCLC patients after immunotherapy (HR=0.480, 95% CI: 0.303-0.759). Sex (HR=0.399, 95% CI: 0.161-0.991, P=0.048), age (HR=0.356, 95% CI: 0.170-0.745, P=0.006) were independent influencing factors of OS of metastatic NSCLC patients after immunotherapy. Conclusions: PD-1/PD-L1 inhibitors are proved to be efficacious and have tolerable toxicities for patients with metastatic NSCLC. Patients at advanced age could still benefit from immunotherapy. Brain metastasis is related to compromised response. Earlier application of immunotherapy in combination with other modalities enhances the efficacy without elevating risk of irAEs. NLR(C1) is an early predictor of clinical outcome. The OS of patients younger than 75 years may be improved when treated with immunotherapy.

UPLC-Q-TOF-MS combined with network pharmacology and experimental verification was used to explore the mechanism of acupoint sticking therapy(AST) in the intervention of bronchial asthma(BA). The chemical components of Sinapis Semen, Cory-dalis Rhizoma, Kansui Radix, Asari Radix et Rhizoma, and Zingiberis Rhizoma Recens were retrieved from TCMSP as self-built database. The active components in AST drugs were analyzed by UPLC-Q-TOF-MS, and the targets were screened out in TCMSP and Swiss-TargetPrediction. Targets of BA were collected from GeneCards, and the intersection of active components and targets was obtained by Venny 2.1.0. The potential targets were imported into STRING and DAVID for PPI, GO, and KEGG analyses. The asthma model induced by house dust mite(HDM) was established in mice. The mechanism of AST on asthmatic mice was explored by pulmonary function, Western blot, and flow cytometry. The results indicated that 54 active components were obtained by UPLC-Q-TOF-MS and 162 potential targets were obtained from the intersection. The first 53 targets were selected as key targets. PPI, GO, and KEGG analyses showed that AST presumedly acted on SRC, PIK3 CA, and other targets through active components such as sinoacutine, sinapic acid, dihydrocapsaicin, and 6-gingerol and regulated PI3 K-AKT, ErbB, chemokine, sphingolipid, and other signaling pathways to intervene in the pathological mechanism of BA. AST can improve lung function, down-regulate the expression of PI3 K and p-AKT proteins in lung tissues, enhance the expression of PETN protein, and reduce the level of type Ⅱ innate immune cells(ILC2 s) in lung tissues of asthmatic mice. In conclusion, AST may inhibit ILC2 s by down-regulating the PI3 K-AKT pathway to relieve asthmatic airway inflammation and reduce airway hyperresponsiveness.

Chinese medicine (CM) has thousands of years of experience in prevention of diseases. As for CM, people's constitution is closely related to their health status, thus recognition of CM constitution is the fundamental and core content of research on constitution types. With development of technologies such as sensors, artificial intelligence and big data, objectification of the four diagnostic methods of CM has gradually matured, bringing changes in the mindset and innovations in technical means for recognition of CM constitution. This paper presents a systematic review of the latest research trends in constitution recognition based on objectification of diagnostic methods in CM.

Objective To evaluate the effects of early exercise intervention in patients who have undergone primary isolated valve surgery. Methods Forty patients scheduled for mitral, aortic, and/or tricuspid valve surgery were allocated to receive a supervised exercise intervention consisting of cycling for 3 min/d at the bedside after operation (intervention group, n=20, mean age [49.05±3.728] years) or to receive no exercise intervention (control group, n=20, mean age [47.95 ± 3.214] years). Oxygen saturation (SpO2) was measured by pulse oximetry continuously before and after the 6-minute walk test. Psycho-educational counseling was provided, and patients were assessed using standard patient questionnaires. Results The arterial SpO2 level increased significantly in the intervention group after exercise compared with the control group (P<0.05). Heart rate returned to baseline in the intervention group postoperatively and was significantly lower than that in the control group (P<0.05). Conclusions A small amount of supervised cycling exercise at the bedside is a safe activity that may improve peripheral arterial SpO2 and reduce heart rate to the baseline level following longer distance walk before discharge in patients who have undergone isolated valve surgery.
