Objective To analyze the effect of the application of the concept of humane care in the ICU patient care. Methods A total of 126 patients in our hospital ICU from December 2013 to February 2015 were treated for analysis objects, and they were divided into two groups, the control group and observation group, and the control group was given routine care, observation group was given humane care treatments, including environmental, psychological and physio-logical care, The nursing satisfaction, physilolgical discomfort and adverse psychological reactions of two groups were compared. Results The satisfaction rate of observation group was 98.41%, the control group was 88.89%;The incidence of physiological discomfort of patients in the observation group was lower than the control group, there was a significant difference(P<0.05);The adverse mental reaction rate of observation group was significantly lower than the control group (P<0.05). Conclusion Application in the ICU nursing care and humane care philosophy helps to improve results, should be widely used.

Objective To analyze the correlation between T lymphocyte subsets,neutrophil/lymphocyte ratio(NLR),procalcitonin(PCT)and the severity of sepsis.Methods A prospective research method was adopted.A total of 78 sepsis patients admitted to the department of intensive care medicine of Zibo Central Hospital from January 2021 to December 2022 were selected as the research subjects.Patients were divided into a septic shock group(37 cases)and a sepsis group(41 cases)based on the severity of their condition,with 40 healthy examinees from our hospital as the healthy control group.Using flow cytometry to measure the levels of CD4+ T lymphocytes count(CD4+ T)and CD8+ T lymphocytes count(CD8+ T)in three groups of subjects,calculate the CD4+ T/CD8+ T lymphocyte ratio(CD4+ T/CD8+ T)and NLR.The levels of PCT and interleukin-6(IL-6)were measured using electrochemiluminescence immunoassay,and the levels of C-reactive protein(CRP)were measured using immunoassay turbidimetry.Acute physiology and chronic health evaluationⅡ(APACHEⅡ)score within 24 hours was recorded for the two groups of patients,and the differences in lymphocyte subsets and various inflammatory indicators were compared between the groups.Pearson correlation analysis was used to analyze the correlation between various indicators and APACHEⅡscore.Results The CD4+ T,CD8+ T,and CD4+T/CD8+T levels in the septic shock and sepsis groups were significantly lower than those in the healthy control group[CD4+ T(×106/L):168.27±76.68,266.08±131.57 vs.789.60±173.78,CD8+ T(×106/L):156.50±68.37,205.81±75.60 vs.636.42±90.59,CD4+ T/CD8+ T:1.09±0.39,1.27±0.34 vs.1.44±0.38,all P<0.01],NLR,PCT,CRP and IL-6 were significantly higher than those in the healthy control group[NLR:25.85±11.62,15.94±8.72 vs.2.68±1.31,PCT(μg/L):21.82±15.28,9.09±4.96 vs.0.13±0.10,CRP(mg/L):158.65±62.33,106.97±51.49 vs.6.48±2.08,IL-6(ng/L):1 344.64±899.21,245.31±176.99 vs.3.25±1.83,all P<0.01].The APACHEⅡscore in the septic shock group was significantly higher than that in the sepsis group(32.00±1.00 vs.22.01±1.09,P<0.05).Correlation analysis showed that the levels of CD4+ T,CD8+ T,CD4+ T/CD8+ T in two groups of sepsis patients were negatively correlated with the APACHEⅡscore(r values were-0.571,-0.506,and-0.555,respectively,all P<0.01),while the levels of NLR,PCT,CRP,and IL-6 were positively correlated with the APACHEⅡscore(r values were 0.711,0.709,0.777,and 0.707,respectively,all P<0.01).Conclusions As the levels of T lymphocyte subsets decrease,inflammatory indicators like NLR and PCT rise,indicating a more severe sepsis condition.Therefore,T lymphocyte subsets and levels of various inflammatory indicators can serve as markers for evaluating the severity of sepsis.

Objective:To explore the role of small molecule glycoprotein Serglycin (SRGN) in chemotherapy resistance of non-small cell lung cancer (NSCLC).Methods:In NSCLC H1299 cell line, shRNA technology was used to interfere with the expression of SRGN and establish stable interfering cell line. Western blot and real time fluorescence quantitative polymerase chain reaction (qRT-PCR) were used to verify the knockdown efficiency; MTS was used to detect the knockdown cell line′s drug sensitivity to cDDP and Oxaliplatin; enzyme linked immunosorbent assay (ELISA), Western blot and qRT-PCR were used to explore the effect of transforming growth factor β (TGFβ) on SRGN and vice versa; Western blot was used to detect the effect of SRGN on epithelial-mesenchymal transition (EMT) related molecules, and online data bioinformatics was used to analyze the correlation between SRGN and EMT related molecules expression; in addition, online prognostic analysis software (kmplot) was used to analyze the correlation between SRGN, TGFβ and prognosis of lung cancer patients.Results:Comparing with the control group, the test group, knocking down SRGN can obviously improve the drug sensitivity of NSCLC cell to cDDP ( P=0.032 7) or Oxaliplatin ( P=0.014 2). TGFβ can enhance the experission of SRGN in NSCLC and SRGN also can help TGFβ secreted from cells. SRGN promotes the epithelial mesenchyme transition by modulating Snail1. By analyzing TCGA database, we found that the expression of SRGN was negatively correlated with the expression of CDH1 (coding for Ecadherin protein) ( r=-0.25) and there was a positive correlation with Snai1 expression ( r=0.37). These results suggest that SRGN can promote the change of EMT in lung cancer cells through TGF β 1 and snail 1. The overall survival time of NSCLC patients with low expression of SRGN was much longer than the patients with high expression of SRGN ( P=0.007 7). The overall survival time of NSCLC patient with low expression in both SRGN and TGFβ1 or TGFβ2 was 73months or 42.8 months longer than that with high expression in both SRGN and TGFβ1/2. Conclusions:Intercting with TGFβ1, SRGN promotes EMT of NSCLC cells, which facilitates the chemoresistence of NSCLC. The simultaneous low expression of SRGN and TGFβ1 or TGFβ2 can significantly prolong the overall survival of patients with NSCLC.

The key pathogenesis of coronary heart disease （CHD） is spleen deficiency and phlegm stasis， and dysfunctional high-density lipoprotein （dys-HDL） may be the biological basis for the occurrence of CHD due to spleen deficiency and phlegm stasis. Considering the biological properties and effects of high-density lipoprotein （HDL）， it is believed that the structure and components of HDL are abnormal in the state of spleen deficiency which led to dys-HDL； and dys-HDL contributes to the formation of atherosclerotic plaques through two major pathways， namely， mediating the dysfunction of endothelial cells and mediating the foaminess of macrophages and smooth muscle cells， thus triggering the development of CHD. It is also believed that dys-HDL is a microcosmic manifestation and a pathological product of spleen deficiency， and spleen deficiency makes foundation for the production of dys-HDL； dys-HDL is also an important biological basis for the phlegm-stasis interactions in CHD. The method of fortifying spleen， resolving phlegm， and dispelling stasis， is proposed as an important principle in the treatment of CHD by traditional Chinese medicine， which can achieve the therapeutic purpose by affecting the changes in the structure and components of dys-HDL， thus revealing the scientific connotation of this method， and providing ideas for the diagnosis and treatment of CHD by traditional Chinese medicine.

OBJECTIVE To explore the effects and mechanism of Huayu qutan formula on atherosclerosis （AS） in ApoE－/－ mice. METHODS Thirty ApoE－/－ mice were randomly divided into model group， Huayu qutan formula group [20 g/（kg·d）]， rosuvastatin group [1.55 mg/（kg·d）]， with 10 mice in each group. Another 10 C57BL/6J mice were selected as normal control group. ApoE－/－ mice were given high-lipid diet for 12 weeks to induce AS model. After modeling， each group was given relevant medicine or normal saline intragastrically， once a day， for 4 consecutive weeks. After the last administration， the levels of total cholesterol （TC）， triglycerides （TG）， low-density lipoprotein cholesterol （LDL-C）， high-density lipoprotein cholesterol （HDL- C）， 5，6-epoxyeicosatrienoic acid （5，　6-EET）， 8，9-EET， 11，12-EET， 14，15-EET， interleukin-1β （IL-1β） and IL-18 in serum were detected； mRNA expressions of inhibitor of nuclear factor κB （IκB）， nuclear factor κB （NF-κB）， NOD-like receptor thermal protein domain associated protein 3 （NLRP3）， Caspase-1， IL-1β and IL-18 in the aortic tissue of mice were detected； protein expression levels of IκB， NF- κB， NLRP3， apoptosis-associated speck-like protein containing CARD （ASC）， Caspase-1， gasdermin D （GSDMD）， IL-1β and IL-18 in the aortic tissue of mice were detected. The morphological changes of the aortic tissue were observed. RESULTS Compared with model group， the serum levels of TC， TG， LDL-C， IL-1β and IL-18， the mRNA expressions of IκB， NF-κB， NLRP3， Caspase-1， IL-1β and IL-18 in aortic tissue， and the protein expressions of IκB， NF-κB， NLRP3， ASC， Caspase-1， GSDMD， IL-1β and IL-18 were all decreased significantly in Huayu qutan formula group and rosuvastatin group （P＜0.05）， while the serum levels of 5，6-EET， 8，9-EET， 11，12-EET and 14，15-EET were increased significantly （P＜0.05）. The aortic atherosclerotic plaques were alleviated significantly. CONCLUSIONS Huayu qutan formula can play role of anti-AS through EETs-mediated pyroptosis.
