Pulmonary complications， the most common postoperative complications of lung cancer， not only affect the quality of life of the patients after surgery but also increase the prognostic risks of postoperative recurrence and metastasis， threatening the life safety. At present， a multidisciplinary model of diagnosis and rehabilitation with integrated traditional Chinese medicine （TCM） and Western medicine has been initially formed under the guidance of the concept of rapid rehabilitation post operation for lung cancer. However， the treatment that only aims at shortening hospital stay and reducing the incidence of postoperative complications does not pay enough attention to the postoperative functional rehabilitation of the lung and the impact of follow-up adjuvant therapy， which affects the completeness of rehabilitation. This paper classifies the typical postoperative symptoms and manifestations of lung cancer into five groups： Lung system， emotion， digestive tract， pain， and nerve. On this basis， this paper summarizes the three core pathogeneses of postoperative complications of lung cancer as failure of Qi to ascend and descend leading to insecurity of defensive exterior， vessel block leading to Qi stagnation and fluid retention， and lung Qi deficiency leading to spleen and kidney deficiency. Accordingly， this paper proposes the treatment principle of protecting healthy Qi and treating Qi with the core of descending-tonifying-ascending-dispersing Qi and puts forward three treatment methods. The first is replenishing Qi and consolidating exterior， and expelling phlegm and regulating lung. The second is replenishing Qi and promoting blood flow to resolve stasis and relieving pain. The third is replenishing Qi and tonifying lung， and invigorating spleen and tonifying kidney. Furthermore， this paper elaborates on the pathogenesis and treatment principles of four common postoperative complications： Lung infection， pleural effusion， atelectasis， and bronchopleural fistula. On the basis of Western medical treatment， the TCM treatment characteristics of treating symptoms in the acute phase and eradicating the root cause in the chronic phase should be played. While dispelling the pathogen， measures should be taken to protect the healthy Qi， including tonifying lung Qi， regulating spleen Qi， and replenishing kidney Qi. This study summarizes the pathogenesis and treatment strategy of common postoperative complications of lung cancer according to the principle of protecting healthy Qi and treating Qi， aiming to provide guidance for the future treatment of postoperative complications of lung cancer.

Objective:To investigate the underlying mechanism behind the significant reduction in intracellular virus loads after respiratory syncytial virus (RSV) and influenza viruses infect respiratory epithelial cells overexpressing the chemokine (C-C motif) receptor 1 (CCR1).Methods:A549 cells were infected with respiratory syncytial virus (RSV), influenza A viruses (H1N1, H3N2), or influenza B virus (FluB), and the expression of chemokine (C-C motif) ligand 5 (CCL5) and CCR1 were detected by qRT-PCR, ELISA, and Western blot. After overexpressing or knocking down CCR1 in A549 cells, these cells were infected with RSV, H1N1, H3N2, or FluB, and the expression of CCR1, heat shock protein 90 (HSP90), cyclin-dependent kinase 1 (CDK1), and viral proteins were detected by qRT-PCR and Western blot. After stimulating CCR1-overexpressed A549 cells with CCL5, Western blot was used to detect the expression of HSP90 and CDK1, and co-immunoprecipitation was used to detect the interaction between HSP90 and CCR1. CCR1 -/- mice were infected with RSV, H1N1, or H3N2 to observe the changes in the expression of HSP90, CDK1, and viral proteins with Western blot, and the inflammation in lung tissues with HE staining. One-way analysis of variance and t test were used for statistical analysis. Results:RSV, H1N1, H3N2, and FluB infections induced high expression of CCL5 in A549 cells ( P<0.05), but the expression of CCR1 showed an overall downward trend. After activating its receptor CCR1, CCL5 inhibited the replication of RSV and influenza viruses by suppressing the activity of HSP90 ( P<0.05). The experiments conducted on CCR1 -/- mice confirmed that the enhanced activity of HSP90 facilitated the replication of RSV and influenza viruses. Conclusion:RSV and influenza viruses may reduce the binding of CCL5 to CCR1 by downregulating the expression of CCR1 in respiratory epithelial cells, thereby weakening the inhibitory effect of CCR1 on HSP90 activity, which enables them to evade host immune defense.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

ObjectiveMolecular docking and animal experiments were employed to explore the protective effect and mechanism of Da Chengqitang （DCQD） on intestinal barrier in septic mice. MethodText mining method was used to screen the active ingredients in DCQD. AutoDock Tools and Discovery Studio were used to study the interactions of active components with the core target proteins ［claudin-1， tumor necrosis factor （TNF）-α， interleukin （IL）-6， endogenous antimicrobial peptide mCRAMP， Toll-like receptor 4 （TLR4）， and myeloid differentiation primary response gene 88 （MyD88）］ in sepsis. Fifty C57BL/6 mice were randomized into sham， model， low- and high-dose （4 g∙kg^-1 and 8 g∙kg^-1） DCQD， and ulinastatin groups （n=10）. Before， during， and after the day of modeling surgery， each group was administrated with corresponding drugs. The mice in other groups except the model group were subjected to modeling by cecal ligation and puncture. Enzyme-linked immunosorbent assay （ELISA） was used measure the serum level of D-lactic acid to assess intestinal mucosa permeability. Hematoxylin-eosin staining was employed to observe the histopathological changes in the ileum and assess the intestinal mucosal damage and inflammatory infiltration. Western blotting was employed to determine the expression levels of tight junction proteins claudin-1 and occludin in the ileal tissue， which were indicative of the bowel barrier function. The TNF-α and IL-6 levels were measured by ELISA to assess the intestinal inflammation. The expression of mCRAMP in the ileal tissue was observed by immunohistochemistry. The mRNA levels of mCRAMP， TLR4， and MyD88 in mouse ileal tissue were determined by Real-time polymerase chain reaction， on the basis of which the mechanism of DCQD in protecting the intestinal barrier of septic mice was explored. ResultMolecular docking results showed that most of the 10 active ingredients of DCQD that were screened out by text mining could bind to sepsis targets by van der Waals force， hydrogen bonding， and other conjugated systems. The results of animal experiments showed that compared with the model group， low- or high-dose DCQD lowered the D-lactic acid level in the serum （P<0.01）， alleviated damage to the ileal tissue and mucosal edema， protected the small intestine villus integrity， reduced inflammatory cell infiltration， promoted the expression of claudin-1 （P<0.01）， lowered the IL-6 level （P<0.01）， up-regulated the mRNA and protein levels of mCRAMP （P<0.01）， and down-regulated the mRNA and protein levels of TLR4 and MyD88 （P<0.01） in the ileal tissue. In addition， high-dose DCQD lowered the TNF-α level and promoted the expression of occludin in the ileum tissue （P<0.01）， and low-dose DCQD up-regulated the protein level of occludin in the ileum tissue （P<0.05）. ConclusionDCQD has a protective effect on intestinal barrier in septic mice. It can reduce intestinal inflammation， repair intestinal mucosal damage， improve the tight junction protein level， and reduce intestinal mucosal permeability by up-regulating the mRNA and protein levels of mCRAMP and the down-regulating the expression of genes in the TLR4/MyD88 pathway.

Lung cancer is the malignant tumor with the highest incidence and mortality among the Chinese.Tumor node metastasis(TNM)staging established by the American Joint Committee on Cancer(AJCC)and International Union Against Cancer(UICC)is a commonly used criterion,but it still has limitations in judging the prognosis of non-small cell lung cancer(NSCLC)patients.With the advantages of real-time and convenient sampling,the immune score based on peripheral blood biomarkers have the ability to predict prognosis and efficacy of NSCLC patients,which have been developed and validated in clinical studies.However,clinical impleruentation of peripheral immune scores is still not widely in NSCLC patients.Therefore,this study introduces and evaluates the 6 peripheral immune scores and reviews the reseach progress of them in the treatment of NSCLC.

Based on the theory of "one qi circulation" founded by HUANG Yuanyu， the core disease mechanism of colorectal cancer is the innate spleen deficiency and stomach qi failing to bear downward， which leads to the turbidity assemble in large intestine， forming the carcinoma toxin， and ultimately transforms into colorectal cancer. The treatment should base on recovering the circulation of qi， Huangya Decoction （黄芽汤） as the basic formula， the circulation of qi ascending and descending as the base， adjusting ascending and descending together with Xiaqi Decoction （下气汤）， and differentiating the syndrome on yin-yang excess-deficiency； for spleen-kidney yang deficiency syndrome， treated with Tianhun Decoction （天魂汤） to supplement liver， kidney and assist yang； for liver-kidney yin deficiency syndrome， treated wtih Dipo Decoction （地魄汤） to supplement lung， kidney， and assist yang. They jointly prompt one qi circulation to provide the thoughts for the treatment of colorectal cancer by traditional Chinese medicine.
