ObjectiveTo study the effect and underlying mechanism of Stemona tuberosa alkaloids on the proliferation and apoptosis of human non-small cell lung cancer NCI-H460 cells. MethodNon-small cell lung cancer NCI-H460 cells were divided into a blank group and S. tuberosa alkaloids groups （50， 100， 150， 200， and 250 mg·L^-1）. The effect of S. tuberosa alkaloids on the proliferation of human NCI-H460 cells was observed by thiazolyl blue tetrazolium bromide （MTT） assay and colony formation assay. Cell apoptosis was observed by Hoechst 33258 staining and flow cytometry. Real-time fluorescence-based polymerase chain reaction （Real-time PCR） was used to detect the effect of S. tuberosa alkaloids on the mRNA expression of cysteinyl aspartate-specific protease 3 （Caspase-3）， B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， and epidermal growth factor receptor （EGFR）. The protein expression levels of Caspase-3， Bax， Bcl-2， protein kinase B （Akt）， phosphorylated （p-）Akt， EGFR， c-Jun N-terminal kinase （JNK）， p-JNK， p38 mitogen-activated protein kinase （p38 MAPK）， and p-p38 MAPK were measured by Western blot. ResultCompared with the blank group， the S. tuberosa alkaloids groups showed increased inhibition rate on cell proliferation （P<0.01）， reduced number of cell clones formed and the rate of cell clonal formation （P<0.05， P<0.01）， and increased karyopyknosis， cytoplasmic aggregation， and cell apoptosis rate （P<0.01）. The S. tuberosa alkaloids groups at 100， 150， 200， and 250 mg·L^-1 showed increased Caspase-3 mRNA expression （P<0.05）， decreased EGFR mRNA expression （P<0.05， P<0.01）， up-regulated protein expression of Caspase-3 and p-JNK （P<0.01）， and down-regulated protein expression of EGFR and p-Akt （P<0.05， P<0.01）. Additionally， compared with the blank group， the S. tuberosa alkaloids groups showed increased expression of Bax mRNA （P<0.01）， decreased expression of Bcl-2 mRNA （P<0.01）， up-regulated protein expression of Bax and p-p38 MAPK （P<0.01）， and down-regulated protein expression of Bcl-2 （P<0.01）. ConclusionsS. tuberosa alkaloids can inhibit proliferation and induce apoptosis of human non-small cell lung cancer NCI-H460 cells， and the mechanism may be related to the inhibition of EGFR protein expression and phosphorylation of Akt protein， as well as the activation of the JNK/p38 MAPK signaling pathway.

ObjectiveTo investigate the effect of Stemona tuberosa alkaloids （STA） on apoptosis and phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） and c-Jun N-terminal kinase/p38 mitogen-activated protein kinase （JNK/p38 MAPK） signaling pathways in human lung cancer A549 cells. MethodA549 cells were classified into blank group and STA groups （100， 150， 200， 250， 300 mg⋅L^-1）. Thiazole blue （MTT） assay and colony formation assay were used to evaluate the proliferation of A549 cells. Apoptosis was observed based on Hoechst 33258 staining， flow cytometry， and Annexin V-FITC/PI staining. Western blot was employed to detect the expression of apoptosis-related proteins cysteine-aspartic acid protease-3 （Caspase-3）， B-cell lymphoma-2 （Bcl-2）-associated X protein （Bax）， and Bcl-2， and the expression of PI3K， phosphorylated （p）-PI3K， Akt， p-Akt， JNK， p-JNK， p38 MAPK， and p-p38 MAPK. ResultCompared with the blank group， STA groups （150， 200， 250， 300 mg⋅L^-1） demonstrated the increase in inhibition rate of cell proliferation （P<0.01） and cell clone inhibition rate， and decrease in cell clone formation rate （P<0.01）. In comparison with the blank group， STA groups showed typical characteristics of apoptosis， such as chromatin condensation and enhanced fluorescence reaction. The apoptosis rate of STA groups was significantly higher than that of the blank group （P<0.01）. Compared with the blank group， STA （150， 200， 250， 300 mg⋅L^-1） significantly up-regulated the protein expression of Caspase-3 and Bax （P<0.05， P<0.01） and down-regulated the expression of Bcl-2 protein （P<0.01）. Compared with the blank group， STA had no significant influence on the total protein expression of PI3K， Akt， JNK， and p38 MAPK. However， STA （150， 200， 250， 300 mg⋅L^-1） significantly decreased the levels of p-PI3K and p-Akt （P<0.05， P<0.01） and increased the level of p-p38 MAPK （P<0.05， P<0.01）. Compared with the blank group， STA （200， 250， 300 mg⋅L^-1） significantly raised the level of p-JNK （P<0.05， P<0.01）. ConclusionSTA can inhibit the proliferation and induce the apoptosis of A549 cells by inhibiting PI3K/Akt signaling pathway and activating JNK/p38 MAPK signaling pathway.

ObjectiveTo study the effect of apigenin on the proliferation and apoptosis of human colon cancer CL187 cells and the underlying mechanisms. MethodHuman colorectal cancer CL187 cells were treated with different concentrations of apigenin （0， 30， 45， 60 mg·L^-1） according to the results of the preliminary experiment. The proliferation of CL187 cells was detected by methyl thiazolyl tetrazolium （MTT） and colony formation assays， and the apoptosis was observed via Hoechst 33258 staining. Real-time fluorescence quantitative PCR was conducted to determine the mRNA levels of cysteine protease-3 （Caspase-3）， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein （Bax） in the CL187 cells treated with apigenin. Western blot was employed to measure the protein levels of Caspase-3， Bcl-2， and Bax associated with apoptosis， protein kinase B （Akt） and phosphorylated Akt （p-Akt） in phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） pathway， and extracellular signal-regulated kinases 1/2 （ERK1/2）， p-ERK1/2， c-Jun N-terminal kinase （JNK）， p-JNK， p38 mitogen-activated protein kinase （MAPK）， and p-p38 MAPK protein in MAPK pathway. ResultCompared with the blank group， the apigenin groups had low cell survival rates and high inhibition rates on cell proliferation （P<0.01）. Apigenin decreased the cell clone number and clone formation rate， and increased the inhibition rate on clone formation （P<0.01）. After CL187 cells were treated with different concentrations of apigenin for 48 h， typical apoptosis characteristics such as nuclear pyknosis， chromatin condensation， and enhanced fluorescence reaction were observed. Compared with blank group， 45， 60 mg·L^-1 apigenin treatments down-regulated the mRNA level of anti-apoptotic gene Bcl-2 （P<0.01） and all the apigenin treatments up-regulated those of the pro-apoptotic genes Bax and Caspase-3 （P<0.05， P<0.01）. Similarly， apigenin treatments down-regulated the protein level of Bcl-2 （P<0.05， P<0.01） and up-regulated those of Caspase-3 （P<0.05， P<0.01） and Bax （P<0.01， 45， 60 mg·L^-1）. The blank group had higher protein level of Akt than the 60 mg·L^-1 apigenin group （P<0.01）， higher protein levels of p-Akt， ERK1/2， and p-ERK1/2 than the 45， 60 mg·L^-1 apigenin groups （P<0.01）， and higher protein levels of JNK and p-JNK than the apigenin groups （P<0.05， P<0.01）. Compared with blank group， 60 mg·L^-1 apigenin up-regulated the protein level of p38 MAPK （P<0.05）， and all the apigenin groups up-regulated that of p-p38 MAPK （P<0.01）. Furthermore， apigenin lowered the p-Akt/Akt ratio （P<0.05， P<0.01） and p-ERK1/2/ERK1/2 ratio （P<0.01）， while it increased the p-JNK/JNK ratio （45， 60 mg·L^-1； P<0.05， P<0.01） and p-p38 MAPK/p38 MAPK ratio （P<0.05， P<0.01）. ConclusionApigenin can inhibit the proliferation and promote the apoptosis of CL187 cells by inhibiting the PI3K/Akt signaling pathway and regulating the expression of proteins in the MAPK signaling pathway.

Glycyrrizae Radix et Rhizoma has high medicinal value and is widely used in compatibility. It is used most frequently in the compatibility of Chinese medicine prescriptions，and is known as ''Guolao''（national medicine） and "master of all medicines". The characteristic active ingredients are mainly liquitin，glycyrrizic acid，glycyrrizin，and licochalcone. In different compatibilities，based on traditional and modern pharmacological theories，the corresponding effect of Glycyrrizae Radix et Rhizoma are brought into play through different mechanisms. Based on the traditional pharmacology of Glycyrrizae Radix et Rhizoma for tonifying spleen，replenishing Qi，clearing heat，removing toxin，dispelling phlegm，relieving cough and pain，and harmonizing various medicines，this paper used herbal authentication to analyze its compatibility application and mechanism. It was found that Glycyrrizae Radix et Rhizoma played corresponding effect in compatibilities through "tonification"，"harmonization"，and "regulation". For example，Glycyrrizae Radix et Rhizoma was combined with tonics including Ginseng Radix et Rhizoma and Atractylodis Macrocephalae Rhizoma to tonify the five Zang-organs through its strong tonifying effect，combined with Paeoniae Radix Alba and Aconiti Lateralis Radix Praeparata to relieve emergencies and pains through harmonizing medicine power and properties，and combined with Rhei Radix et Rhizoma and Natrii Sulfas to reduce medicine intensity through regulating medicine properties and body characteristics. The application law and mechanism of the modern pharmacological compatibility of Glycyrrizae Radix et Rhizoma were analyzed by data mining and network pharmacology. It was found that the modern clinical formula was often compatible with Glycyrrizae Radix et Rhizoma for anti-inflammation，cardiovascular and cerebrovascular protection，anti-virus，and anti-tumor，Ephedrae Herba and Scutellariae Radix for anti-inflammation，Bambusae Caulis in Taenias，Salviae Miltiorrhizae Radix et Rhizoma，and Aurantii Fructus Immaturus for cardiovascular and cerebrovascular protection，and Ophiopogonis Radix and Chuanxiong Rhizoma for nerves protection. Meanwhile，the important targets of the characteristic ingredients were protein kinase B1 （Akt1），interleukin-6 （IL-6），tumor necrosis factor （TNF），and epidermal growth factor receptor （EGFR）. The important characteristic pathways such as tyrosine kinase inhibitor resistance pathway and cyclic guanosine monophosphate （cGMP）/protein kinase G （PKG） signal pathway played the role of cardiovascular and cerebrovascular protection，and proteoglycan pathway in cancer played a neuroprotective role. This study is expected to provide references for the rational compatibility and application of Glycyrrizae Radix et Rhizoma，as well as the compatibility application of Chinese medicine prescriptions.

Piperine is a kind of amide alkaloids presenting in Piper nigrum L.，which has the pharmacological action such as protecting cardiovascular system ，regulating glucose and lipid metabolism ，anti-tumor，improving nervous system diseases ， anti-inflammation and so on. This paper summarized the pharmacological action and mechanisms of piperine in recent years and found that piperine ，as the main active ingredient of P. nigrum ，could protect the cardiovascular system by reducing inflammation and oxidative stress ；improve mitochondrial function through anti-inflammatory and antioxidant effects ，thereby regulate glucose and lipid metabolism ；play an anti-tumor role by mediating the signaling pathways of Wnt/β-catenin，NF-κB/Nrf-2/KeAP-1/HO-1， PI3K/Akt，TGF-β1/Smad2/ERK1/2；improve neurological diseases by inhibiting autophagy ，relieving inflammation ，improving antioxidant，inhibiting neuronal apoptosis and regulating the expression of related proteins in neurons ；play an anti-inflammatory effect by inhibiting the activity of NF-κB and other signaling pathways and reducing the expression of inflammation-related proteins. However，the mechanism of action of piperine is not perfect ，and most of the studies have been confined to the pharmacological level or a certain signaling pathway and a certain target ，without being able to elucidate the interconnection between the relevant signaling pathway and the specific target from a holistic perspective. In the follow-up ，the specific targets of piperine can be identified and clinical trials can be carried out to provide support for the clinical application of piperine.

Objective:To investigate the clinical value of nutritional indexes including body mass index (BMI), albumin (ALB), nutrition risk screening 2002 (NRS 2002) and the nutrition risk in critically ill score (NUTRIC) in 28-day prognosis of patients with sepsis related acute kidney injury (AKI).Methods:A prospective cohort study was conducted. Patients with sepsis treated in the emergency intensive care unit (EICU) of China Rehabilitation Research Center from December 1, 2018 to December 1, 2020 were observed for 7 days. Patients with sepsis related AKI were enrolled in this study. The gender, age, BMI, basic diseases, shock, number of affected organs, length of hospital stay, ALB, mechanical ventilation (MV) and vasoactive drug use, sequential organ failure score (SOFA), rapid sequential organ failure score (qSOFA) and acute physiology and chronic health evaluationⅡ(APACHEⅡ) were recorded. The NRS 2002 score and NUTRIC score were calculated. Cox regression model was used to analyze the risk factors of 28-day mortality in patients with sepsis related AKI. The receiver operator characteristic curves (ROC curves) were drawn and the areas under the ROC curves (AUC) were calculated, and the value of BMI, ALB, NRS 2002 score and NUTRIC score was analyzed to predict 28-day mortality in patients with sepsis related AKI. Kaplan Meier survival curves were used to analyze the effects of NRS 2002 score and NUTRIC score stratification on the 28 day prognosis of patients with sepsis related AKI.Results:A total of 140 patients with sepsis related AKI were enrolled, including 73 survival patients and 67 died patients within 28 days. The 28-day mortality was 47.9% (67/140). BMI in the survival group was significantly higher than that in the death group [kg/m 2: 22.0 (19.5, 25.6) vs. 20.7 (17.3, 23.9), P < 0.05], and NRS 2002 score and NUTRIC score were significantly lower than those in the death group [NRS 2002 score: 5 (4, 6) vs. 7 (6, 7), NUTRIC score: 6 (5, 7) vs. 7 (6, 9), both P < 0.05]. The ALB of the survival group was slightly higher than that of the death group, but the difference was not statistically significant. Cox regression analysis showed that NRS 2002 score and NUTRIC score were independent risk factors for 28-day death in patients with sepsis related AKI. ROC curve analysis showed that NUTRIC score had the strongest predictive ability for 28-day death [AUC = 0.785, 95% confidence interval (95% CI) was 0.708-0.850], followed by NRS 2002 score (AUC = 0.728, 95% CI was 0.647-0.800), but there was no significant difference between them. Compared with NRS 2002 score, the predictive ability of BMI and ALB was poor. Kaplan-Meier curve analysis showed that the prognosis of patients with NRS 2002 score≥5 was significantly worse than that of patients with NRS 2002 score < 5 (28-day cumulative survival rate: 42.1% vs. 75.6%, Log-Rank test: 2 = 11.884, P = 0.001), and the prognosis of patients with NUTRIC score≥6 was significantly worse than that of patients with NUTRIC score < 6 (28-day cumulative survival rate: 40.4% vs. 86.1%, Log-Rank test: 2 = 19.026, P = 0.000). Conclusions:Patients with sepsis related AKI have high nutritional risk. Both NRS 2002 score and NUTRIC score have good predictive value for the prognosis of patients with sepsis related AKI, while BMI and ALB have low predictive value. Due to the complex calculation of NUTRIC score, NRS 2002 score may be more suitable for emergency department.

Objective: To explore the effect of case management on postoperative affected limb lymphedema in breast cancer patients. Methods: This study is a non-concurrent control trial. A total of 157 cases of breast cancer patients who met the inclusion/exclusion criteria were selected from the Sun yet-sen University Cancer Center from June 2016 to July 2017 and from June 2016 to July 2017 by the convenient sampling method. Among them, 80 patients from June to July 2016 were listed as the control group, and 77 patients from June to July 2017 were listed as the intervention group. The control group implemented the routine nursing mode of breast cancer. The intervention group implemented case management on the basis of routine nursing. Lymphedema of the affected limb were compared between the two groups before intervention, 3 months after surgery, 6 months after surgery and 1 year after surgery. Results: The incidence of postoperative lymphedema (OR=2.467, 95%CI1.177-5.169, P<0.05) of the affected limb was lower in the intervention group than in the control group. The incidence of lymphedema in the limbs of the two groups was not statistically different 3 months after operation (χ²=0.617, P>0.05). There was a statistically significant difference between the two groups 6 months after operation (χ²=5.835, P<0.05) and 1 year after operation (P=0.003). The incidence of lymphedema in the affected limbs in the experimental group was lower than that in the control group. There was an increased incidence of lymphedema in the control group, the incidence of side pain, but an incidence of lymphedema in the intervention group was in a downward trend. Conclusion Case management mode can effectively prevent and improve the occurrence of postoperative lymphedema in patients with breast cancer.

Objective To investigate the predictive value of the whole nodule size and solid component size of lung adenocarcinoma manifesting as subsolid nodule(SSN) in three different dimensions for pathologic grade.Methods We evaluated retrospectively preoperative chest HRCT data of 125 patients with 127 SSNs surgically resected and pathologically conformed lung adenocarcinomas.All specimens were divided into two groups: a total of 69 SSNs in group A, including 22 AIS and 47 MIA;a total of 58 SSNs in group B, only including IAC.Computer aided diagnosis software were used to measure the one dimension maximum diameter of solid component with lung window setting(1D-SCLW),two dimension maximum diameter of solid component with lung window setting(2D-SCLW),one dimension maximum diameter of solid component with mediastinal window setting(1D-SCMW),two dimension maximum diameter of solid component with mediastinal window setting(2D-SCMW),one dimension maximum diameter of whole nodule with lung window setting (1D-WNLW), two dimension maximum diameter of whole nodule with lung window setting (2D-WNLW), and volume of solid component with threshold of-300 HU (SCT) of all SSNs.Results 1D-SCLW, 2D-SCLW,1D-SCMW,2D-SCMW,1D-WNLW,2D-WNLW and SCT of the group B were significantly larger than those of the group A(P=0.000).ROC analyses indicated that the diagnostic efficiency of SCT for the pathologic grade was the highest among 7 CT features(AUC=0.887, sensitivity:81%,specificity:93%);The cut-off values of 1D-SCLW,2D-SCLW,1D-SCMW,2D-SCMW,1D-WNLW, 2D-WNLW and SCT were 17.50 mm,14.75 mm,9.50 mm,7.75 mm,0.50 mm,1.25 mm and 139.00 mm3.Multiple Logistic regression analysis revealed that SCT was the independent predictor of pathologic grade(OR=4.978,95%CI=1.430-17.331,P=0.012).SCT of 139.00 mm3 or greater was a significant indicator of IAC.Conclusion Among the whole nodule size and solid component size of SSN in three different dimensions on preoperative HRCT, SCT is found to be the independent predictor of pathologic grade, which may provide reference for surgery.
