Lung cancer is the malignant tumor with the highest incidence and mortality rates globally. Current treatment methods for lung cancer primarily include surgery， chemotherapy， targeted therapy， and immunotherapy. However， the main limitations of these treatments are their side effects， the drug resistance， and the economic burden they impose. As a critical cancer pathway， the Janus kinase （JAK）/signal transducer and activator of transcription （STAT） signaling pathway regulates tumor occurrence and development through multiple mechanisms by influencing various downstream targets. Consequently， the JAK/STAT signaling pathway offers a promising avenue for lung cancer treatment research. Numerous studies have demonstrated that the JAK/STAT signaling pathway plays a key role in the proliferation and growth of lung cancer cells， angiogenesis， epithelial-mesenchymal transition （EMT）， metabolic alterations， remodeling of the immune microenvironment， and the development of treatment resistance. Traditional Chinese medicine （TCM） has garnered increasing attention due to its minimal side effects， low economic burden， and its potential to enhance efficacy and reduce toxicity when used in conjunction with Western medicine. In addition to traditional Chinese medicine compounds， a growing number of Chinese medicine monomers have come into the spotlight because of their more targeted effects. Numerous studies investigating the regulation of the JAK/STAT signaling pathway by TCM in the treatment of lung cancer have demonstrated that TCM can inhibit the proliferation and invasion of lung cancer cells， tumor angiogenesis， and EMT， improve the inflammatory and immunosuppressive microenvironments， and enhance treatment sensitivity by intervening in the JAK/STAT signaling pathway， thereby impeding the progression of lung cancer. In recent years， the research on the regulation of this pathway by TCM in the treatment of lung cancer has been updated rapidly. However， the summary of these studies has not been updated in time. This review summarizes and reflects on the recent research findings regarding the regulation of the JAK/STAT signaling pathway by TCM to intervene in lung cancer from three aspects， introducing the JAK/STAT pathway， elaborating the mechanism of this pathway in lung cancer， and exploring the intervention of TCM in the treatment of lung cancer through this pathway， to provide more reference for the treatment of lung cancer in the future.

BACKGROUND: Electroacupuncture (EA) treatment is efficacious in patients with respiratory disorders, although the mechanisms of its action in lung-function protection are poorly understood. This study aimed to explore the neuroanatomical mechanisms of EA stimulation at the BL13 acupoint (Feishu, EA-BL13) improvement in asthma. METHODS: Allergic asthma was induced by intranasal 2.0% ovalbumin (OVA) instillation combined with intraperitoneal injection of the 10.0% OVA. The levels of interleukin (IL)-4 and IL-5 were detected by enzyme-linked immunosorbent assay. Hematoxylin and eosin and periodic acid-schiff stain were used to evaluate inflammatory cell infiltration and mucus secretion. Cellular oncogene fos induction in neurons after EA stimulation was detected by immunofluorescent staining. The messenger RNA expression levels of adrenergic receptors were quantified with real-time polymerase chain reaction. RESULTS: EA improved airway inflammation and mucus secretion mainly by activating somatosensory-sympathetic pathways ( P <0.001). Briefly, the intermediolateral (IML) nuclei of the spinal cord received signals from somatic EA stimulation and then delivered the information via the sympathetic trunk to the lung. Excited sympathetic nerve endings in lung tissue released large amounts of catecholamines that specifically activated the β2 adrenergic receptor (β2AR) on T cells ( P <0.01) and further decreased the levels of IL-4 and IL-5 ( P <0.001) through the cyclic adenosine monophosphate/protein kinase A signaling pathway. CONCLUSION This study provided a new explanation and clinical basis for the use of EA-BL13 as a treatment for allergic asthma in both the attack and remission stages and other respiratory disorders related to airway inflammation.

Myeloproliferative neoplasms (MPN) are a group of clonal disorders of hematopoietic stem cells, and JAK2 V617F gene mutation is the main basis for the diagnosis of MPN. Previous studies have shown that BCR-ABL fusion gene and JAK2 V617F gene mutation are mutually exclusive in MPN patients, but in recent years, patients with a double mutation of both genes are often reported. The article synthesizes the relevant domestic and foreign literature in recent years, and reviews the BCR-ABL fusion gene and JAK2 V617F mutation double-positive MPN.

Objective:To explore the clinical utility of liquid chromatography tandem mass spectrometry forprimary aldosteronism screening.Methods:From January to October 2019, 413 inpatients diagnosed hypertension from Fuwai Hospital of Chinese Academy of Medical Sciences were enrolled, including 60 Primary aldosteronism(PA)patients and 353 primary hypertension patients. The plasma aldosterone concentration (PAC) and renin concentration (DRC) were measured after 2 h of standing. The 24 h urine samples were collected for measurement of aldosterone using LC-MS/MS. The performance of urine aldosterone and urine aldosterone/renin ratio (UADRR) in PA screening was evaluated by ROC, and compared with PAC/DRC ratio (ADRR). Meanwhile, the efficiency of urine aldosterone in elderly patients or patients with low blood potassium or 24 h urine sodium over 200 mmol was investigated.Results:Area under the curve (AUC)of urine aldosterone was 0.725 (95 %CI 0.679-0.767), and the best cut-off was 7.13 μg/24 h, which was lower than AUC of ADRR (0.958, 95 %CI 0.934-0.975). The AUC of UADRR was 0.947 (95 %CI 0.920-0.966), the best cut-off was 1.11 (μg/24 h)/(μIU/ml), the sensitivity and specificity were 91.7% and 89.0%, respectively. There is no significant differences found with ADRR. In patients with 24 h urine sodium over 200 mmol, AUC of aldosterone was 0.834 (95 %CI 0.730-0.910) and the best cut-off was 9.31 μg/24 h. The sensitivity and specificity were 90.9% and 68.7%, respectively. For the elderly patients over 60 years old, the AUC of urinary aldosterone was 0.860 (95 %CI 0.770-0.925), and the best cut-off was 6.91 μg/24 h. The sensitivity and specificity were 84.6% and 81.3%, respectively. When admission blood potassium was less than 3.50 mmol/L, AUC of urinary aldosterone was 0.822 (95 %CI 0.684-0.917), and the best cut-off was 10.63 μg/24 h. The sensitivity and specificity were 85.7% and 66.7%, respectively. Conclusion:The detection of aldosterone in urine by LC-MS/MS can provide clinical information for PA screening, and the screening performance is better in patients with 24-hour urine sodium over 200 mmol, elderly patients or patients with low blood potassium. If combined with renin, screening efficiency was the same as that in ADRR.

Objectives To evaluate the role of PCSK9 (proprotein convertase subtilisin kexin type 9) on the lipid accumulation and kidney injury of C57BL/6 mice. Methods The 24 h urine of 12 weeks old wide type C57BL/6 mice and PCSK9 knockout (KO) mice were collected through a metabolic cage, followed by perfusion and sacrifice. Urinary microalbumin?to?creatinine ratio (UACr), total cholesterol and triglyceride in kidney tissues were measured by ELISA. BODIPY 493/503 staining and standard transmission electron microscopy (TEM) of kidney tissues was performed for evaluating lipid accumulation and podocyte foot effacement in the kidney. Kidney tissues were also evaluated by PAS stain and TUNNEL stain. PCSK9, podocin and nephrin were quantified through real?time PCR, and the Bcl?2, Bax and cleaved caspase 3 were evaluated by Western blotting. Results Total cholesterol and triglyceride contents were higher in the kidneys of PCSK9 KO mice than controls (P<0.05). The level of lipid accumulation in glomeruli and tubules through BODIPY 493/503 stain, and the amount of lipid drop in TEM were more serious in PCSK9 KO mice. UACr and podocyte foot process effacement were increased, and the transcription of podocin and nephrin were decreased in the kidneys of PCSK9 KO mice (all P<0.05). The expression of Bcl?2 was decreased, and Bax and cleavedcaspase 3 were increased in the kidney samples of PCSK9 KO mice. Conclusion PCSK9 might be reversely involved in lipid homeostasis and accumulation, resulting in injury and apoptosis in the kidneys of C57BL/6 mice.

Objective To investigate the expression of IL-24 in patients with non-small cell lung cancer (NSCLC),and to evaluate its influence on the bioactivity of NSCLC cells. Methods Thirty-nine patient with NSCLC (23 patients with adenocarcinoma and 16 patients with squamous carcinoma) and 17 healthy subjects were enrolled in this study. Serum samples and lung cancer tissues were collected. IL-24 expression in the serum samples was measured using enzyme-linked immunosorbent assay. Its expression at mRNA level in the lung cancer tissues was measured using reverse transcriptional real-time PCR. Adenocar-cinoma cell line A549 and squamous carcinoma cell line NCI-H520 were stimulated with recombinant human IL-24 (10 ng/ml and 100 ng/ml) for 24 hours. Cell proliferation was measured using CCK-8 method. Ap-optosis and cell cycle were measured using flow cytometry. Cell invasion was measured using Transwell as-say. Results Serum IL-24 was significantly elevated in patients with NSCLC in comparison with that in healthy subjects [(144.10±64.43) vs(48.47±18.00) pg/ml]. No significant difference in IL-24 expres-sion was found between patients with adenocarcinoma and squamous carcinoma. IL-24 expression at mRNA level in lung cancer tissues of patients with NSCLC was also significantly increased with an approximately 5-fold enhancement in comparison with that in normal lung tissues. Stimulation with low concentration of re-combinant IL-24(10 ng/ml) promoted the proliferation and suppressed the apoptosis of A549 and NCI-H520 cells. In contrast, high concentration of recombinant IL-24 (100 ng/ml) stimulation notably inhibited the proliferation and enhanced the apoptosis of lung cancer cell lines. No remarkable changes in cell cycle of the two kinds of lung cancer cells in response to IL-24 stimulation were observed. Moreover,low concentration of recombinant IL-24 (10 ng/ml) did not affect the invasion of A549 and NCI-H520 cells,while high concen-tration of recombinant IL-24 (100 ng/ml) significantly inhibited the invasion of lung cancer cells. Conclu-sion IL-24 might influence the bioactivity of NSCLC cells in a concentration-dependent manner. High con-centration of IL-24 might counteract the invasion and metastasis of NSCLC,which is important to prevent dis-ease promotion.

Objective To investigate the effects of 12-lipoxygenase (12-LO) and angiotensin Ⅱ (Ang Ⅱ) on the CIP/KIP family of cyclin-dependent kinase inhibitors (CKIs) p21,p27 and p57 related to cell hypertrophy.Methods Mesangial cells were treated with high glucose for 24 hours and 48 hours respectively.12(S)-hydroxyeicosatetraenoic acid [12(S)-HETE] and Ang Ⅱ were infused to rats by osmotic mini-pump for 1 week and 2 weeks respectively.Rats fed high fat diet were received low dose streptozotocin (STZ) to make type 2 diabetes (DN).The rats were divided into normal control group,DN group,DN+Ang Ⅱ type 1 receptor blocker (ARB) group or 12-LO inhibitor (CDC) group.DN+ARB rats were treated by losartan for 6 weeks,and DN+CDC rats were treated for 8 weeks.Urine albumin and protein expressions of p21,p27 and p57 were detected by ELISA and Western blotting respectively.Glomeruli injury and expressions of p21 and p27 were detected by PAS staining and immunohistochemistry respectively.Results High glucose increased p21 and p27 protein expression in mesangial cells significantly compared with the relative control (all P ＜ 0.05),but had no effect on p57.Ang Ⅱ increased p27 protein expression in gloneruli significantly (P ＜ 0.05),but had no effect on p21 and p57 protein expression.12(S)-HETE increased both p21 and p27 protein expression in glomeruli significantly (all P ＜ 0.05),but had no effect on p57 protein expression.Blood glucose,kidney/body weight,urinary protein,and glomerular p21 and p27 protein expressions were increased in DN group (all P ＜ 0.05) compared with those in control group,with little change of p57 protein expression (P ＜ 0.05).Moreover,glomerular hypertrophy and extra cellular matrix accumulation were observed in DN group.However,urine protein,kidney/body weight,renal injury,but not blood glucose,were decreased in DN+ARB group and DN+CDC group compared with DN group respectively (P＜ 0.05).Further DN+CDC rats had decreased both p21 and p27 protein expressions in glomeruli,but DN+ ARB rats only had decreased p27 protein expression (all P ＜ 0.05).Conclusions 12-LO may induce both p21 and p27 protein expression in DN glomeruli,but Ang Ⅱ may induce only p27 expression.

Objective:To determine the effects of Foxp3-overexpressing lung cancer cells on activated CD4+T lymphocyte.Methods: Stable Foxp3-overexpressing lung cancer cells NCIH-1299,NCIH-hFoxp3,was generated by transfection of NCIH-1299 cells with plasmid pcDNA3-hFoxp3 mediated by Lipofectamine 2000 and by selection with G418,and validated by quantitative PCR and Western blot.The expression levels of IL-8 and IL-10 secreted by NCIH-hFoxp3 and NCIH-control were measured by ELISA.IL-2 secrection by activated human CD4+T lymphocyte which was tested after stimulation with 20% conditioned medium of NCIH-hFoxp3 and NCIH-control cells.The proliferation of activated human CD4+ T lymphocytes was assessed by MTT after coculture with NCIH-hFoxp3 cells.The adhesive ability of activated human CD4+ T lymphocytes was probed with NCIH-hFoxp3 cells by immunocytochemistry.Results: Compared with NCIH-control cells,NCIH-hFoxp3 secreted high level of IL-10 and low level of IL-8.NCIH-hFoxp3 with Foxp3 overexpression significantly suppressed the proliferation,adhesive potential and IL-2 expression by activated CD4+ T cells.Conclusion: Suppression of immune activities of activated CD4+ T cells by Foxp3 overexpression in lung cancer cells may correlate with cytokine IL-8 and IL-10,which can contribute lung cancer progression.

Objective:To determine the effects of enforced expression of Foxp3 in lung cancer cell with regards to proliferation and tumorgeneity. Methods: A stable subline NCIH-hFoxp3 was established by liopfectamin-mediated pcDNA plasmid transfection carrying exogenous hFoxp3. The growth curve and secrection of IL-8 and IL-10 of NCIH-hFoxp3 were evaluated using MTT and ELISA, respectively. The in vivo tumorigeneity was assessed as well by inoculation of NCIH-hFoxp3 subcutaneously in nude mice. Results:Lung cancer cell NCIH-hFoxp3 with enforced expression of Foxp3 proliferated slowly but exihited increased in vivo tumorgeneity compared with corresponding control subline. In addition,increased expression of hFoxp3 in NCIH-hFoxp3 augmented secretion and at-tenuated secretion of IL-8 and IL-10,respectively. Conclusion:Increased expression of Foxp3 may promote progression of lung cancer cell by change of cellular microenvironment and evasion of immune surveillance.
