Objective Looking for the chemical components which have positive correlations with anti-inflammatiory activity of Flos Lonicerea to set up pharmacodynamic-fingerprint. Methods To gain the fingerprints of different parts by HPLC and to detect the pharmacological activities of anti-inflammation, then the correlationship between chemical components and pharmacological activities were detected by linear regression. Results Pharmacological activities of the methanol extracted part were best of all, so the fingerprint of the methanol part could represent the pharmacodynamic-fingerprint of Flos Lonicerea. Conclusion The fingerprint established by this way is more scientific and reasonable.

OBJECTIVE:To establish the method for simultaneous determination of 6 components in Lonicera japonica,and to study the content changes of them before and after before and after carbonized. METHODS:UPLC method was adopted. The deter-mination was performed on Agilent Eclipse Plus C18 RRHD column with mobile phase consisting of 0.1% phosphoric acid solu-tion-acetonitrile(gradient elution)at the flow rate of 0.2 mL /min. The detection wavelength was set at 350 nm,and column tem-perature was 25 ℃. The sample size was 1 μL. RESULTS:The linear ranges of chlorogenic acid,rutin,galuteolin,isochlorogenic acid A,isochlorogenic acid B and isochlorogenic acid C were 21.2-424 μg(r=0.9993),1.17-23 μg(r=0.9995),2.18-43 μg(r=0.9998),5.10-102 μg(r=0.9993),2.60-52 μg(r=0.9991),4.95-99 μg(r=0.9998),respectively. RSDs of precision,stability and repeatability tests were all lower than 2.0%. Recoveries were 97.11%-99.76%(RSD=1.20%,n=6),95.20%-99.90%(RSD=2.20%,n=6),95.71%-100.30%(RSD=2.20%,n=6),95.00%-96.98%(RSD=0.88%,n=6),96.47%-103.00%(RSD=2.40%, n=6),95.78%-103.80%(RSD=3.20%,n=6). Compared with before processing,the contents of rutin,isochlorogenic acid B and isochlorogenic acid C in L. japonica were increased along with processing,the contents of chlorogenic acid and isochlorogenic acid A were decreased significantly,while the content of galuteolin had no significant change. CONCLUSIONS:The method is sim-ple,precise,stable and repeatable,and can be used for simultaneous determination of 6 components in L. japonica. Those chemi-cal components have certain changes before and after carbonized.

Objective To explore the expression of miR-146a and its target gene LIN52 in advanced gastric cancer and their potential impact on clinical prognosis.Methods Total RNAs were extracted from 93gastric cancer tissues and their corresponding adjacent non-tumor tissues to quantify the relative expression of miR-146a by using real-time quantitative PCR (RT-qPCR).Expression of LIN52 was detected in tumors and normal tissues by immunohistochemistry.Correlation analysis was assessed between the expression of miR-146a and LIN52 and clinicopathological parameters,including clinical diagnostic specificity,tumor TNM staging,lymph node metastasis,differentiation grade,curative effect and prognosis of gastric cancer.Results The expression of miR-146a in gastric carcinoma was negatively correlated with lymph node metastasis (P ＜0.05).The expression of miR-146a had a significant correlation with the prognosis of the patients (P ＜ 0.01).The patients with high expression of miR-146a had higher survival rate (P ＜ 0.05),but the patients with high expression of LIN52 had lower survival rate (P ＜ 0.05).The receiver operating characteristic curve regression analysis showed that sensitivity and specificity of miR-146a were 94.1％ and 61.5 ％ to diagnose gastric cancer.Conclusions As a tumor suppressor gene in gastric cancer,miR-146a has significantly negative correlation with LIN52.High expression of miR-146a in the gastric cancer tissue might be associated with improved treatment efficacy of chemotherapy,suggesting that miR-146a may be a molecular marker for the diagnosis and prognosis of gastric cancer.

This study was aimed to explore the characteristics of urine metabolomics among HIV/AIDS patients with spleen-lung qi-deficiency. H-NMR technique was combined with principal component analysis and cluster analysis in the comparison of urine metabolic products among 24 HIV/AIDS cases with spleen-lung qi-deficiency and 20 healthy control cases. The results showed that urine metabolic products of HIV/AIDS patients with spleen-lung qi-deficiency and healthy people by H-NMR technique detection and PLS-DA analysis can classify the outline of urine metabolites. There were about 20 variables in the difference between two groups. The speculated substances contained glycyl-L-leucine, L-valine, α-aminobutyric acid, methyl succinic acid, glycine propionyl, and etc. It was concluded that H-NMR technique was able to classify the outline of urine metabolites between HIV/AIDS cases with spleen-lung qi-deficiency and healthy people. Part of the potential existed characteristic markers contributed to the clinical diagnosis of traditional Chinese medicine (TCM) syndrome differentiation of AIDS. It had certain effect in its quantitative analysis.

OBJECTIVETo evaluate the efficacy and safety of autologous cytokine-induced killer (CIK) cell t combined with XELOX regimen in treatment of senile advanced gastric cancer.

METHODSForty-six cases of senile advanced gastric cancer patients with a mean age of 70 years were prospectively divided into two groups according to individual acceptance of CIK cells: 25 patients receiving autologous CIK cell treatment combined with XELOX regimen (trial group) and 21 patients receiving simple chemotherapy (control group). Patients in CIK group were matched to those in control group by sex, ages, KPS ranking scores, histological type, pathological grade, and clinical stage. Immune reaction, adverse reaction, time to progression (TTP) and overall survival (OS) were evaluated.

RESULTSHost immune function was increased (P<0.05) and the adverse reaction was decreased in patients of trial group as compared to control group. There were no significant differences in response rate (RR)(33.3% vs. 23.1%, P>0.05), disease control rate (DCR)(86.7% vs. 80.8%, P>0.05) between the two groups. TTP (4.8 months vs. 3.1 months, P<0.05) and OS (7.1 months vs. 5.9 months, P<0.05) in trial group were significantly improved as compared to control group.

CONCLUSIONAutologous CIK cells combined with XELOX regimen can increase immune function, improve clinical efficacy, decrease adverse reaction and prolong OS for senile patients with advanced gastric cancers.

Objective To investigate the effect of Zinc finger E-box binding homeobox protein 1 (ZEB1) on the radiosensitivity of gastric cancer cells AGS and its possible mechanism. Methods AGS cells were irradiated by X-rays at different doses (0, 2, 4, 6, and 8 Gy). Western blot was used to observe the expression of ZEB1 in cells. AGS cells, in logarithmic growth phase, were transfected with of ZEB1 gene or its interference plasmids, the corresponding control plasmids ( pcDNA3. 1 ) and negative control interference plasmids. They were classified as overexpression ZEB1 group, silencing ZEB1 group, control group and negative control group, respectively. The effect of overexpression and silencing ZEB1 on the survival of AGS cells after irradiation were analyzed by colony formation assay. The cell apoptosis rate was analyzed by flow cytometry. The expressions of histone H2A (H2AX), phosphorylated H2AX (γ-H2AX) and telangiectasia mutated gene (ATM) were detected by Western blot. Results The expression of ZEB1 in AGS cells was dependent on radiation dose (F=58. 57, P<0. 05). Overexpression of ZEB1 increased AGS cells viability, inhibitedγ-H2AX expression (t=12. 18, P<0. 05), blocked cell apoptosis (t=7. 27, P<0. 05) and up-regulated ATM expression in time-dependent manner after irradaition (F=165. 70, P <0. 05). Silencing ZEB1 reduced AGS cells viability, increased γ-H2AX expression ( t =12. 88, P<0. 05) and cell apoptosis (t =8. 36, P <0. 05), and down-regulated of ATM expression (F=44. 80, P<0. 05). Conclusions ZEB1 regulates the radiosensitivity of gastric cancer AGS cells by up-regulating ATM expression.

Objective: To investigate the application of 3D-printed minimally-invasiveguided template in the treatment of recurrent cer-vical cancer after surgery, assisting interstitial brachytherapy. Methods: From July 2017 to April 2018, a total of 10 patients admitted to Cangzhou Hospital of Integrated Traditional Chinese and Western Medicine in Hebei province with recurrent cervical cancer after radi-cal surgery underwent the 3D-printed customized template-assisted interstitial brachytherapy. According to the specific conditions of patients, different vaginal localization templates were selected for CT simulation localization. The main guidance needle space distribu-tion was designed, and 3D minimally-invasive guidance templates were printed. Then, needles were inserted according to the main guide channel of the template commissioned by medical photosensitive resin. The high-risk clinical target volume (HR-CTV) of 6 Gy/fraction was administered (4 to 6 fractions). Results: Overall, 10 patients were treated with implantation for a total of 52 times. Treat-ment with average scanning CT number for each brachytherapy was (1.58±0.70) times. The average elapsed time for each brachythera-py implant treatment, from plug implant to inserting planting needle satisfactorily with the location of the tumor, was (10.88±2.94) minutes. The mean number of metal needles used was (5.69±1.91) in each brachytherapy. The mean D90 value for high-risk clinical tar-get volume (HR-CTV) was (6.41±0.29) Gy. The cumulative D2cm3 values for the bladder, rectum, and sigmoid colon were (4.75±0.37) Gy, (3.93±0.26) Gy, and (4.33±0.24) Gy, respectively. After 3 months of treatment, the efficacy was evaluated in 8 cases with CR and 2 cas-es with PR. Conclusions: The technology of 3D-printed minimally-invasive guided template shows the advantage of accurate location and superior repeatability in the application of interstitial brachytherapy in treating recurrent cervical cancer after operation, which in-volves less time and insertion needles. The patients had minor aches and few complications. The tumor shrank significantly, which indi-cated a bright future of the technology's clinical application.

OBJECTIVE： To observe the effects of Shenfu yixin decoction on reactive oxygen species （ROS） and energy metabolism in primary hypoxic cardiomyocytes. METHODS： After isolation， culture and identification， primary cardiomyocytes of neonatal SD rats were randomly divided into normal group， model group， positive control group （coenzyme Q10， 0.1 mmol/L） and Shenfu yixin decoction low-dose and high-dose groups （0.25， 0.5 mg/mL）. Except for normal group， other groups were cultured with 5％O2， 5％CO2 and 90％N2 for 6 h to induce hypoxic injury model. After 6 hours of hypoxia， ROS contents in cardiomyocytes and mitochondria of each group were detected by ROS probe and flow cytometry. Luciferase luminescence and Western blotting were used to detect ATP content and CK protein expression of each group. Transmission electron microscope was used to observe ultrastructure of cardiomyocytes in each group. RESULTS： Compared with normal group， the expression of ROS in primary hypoxic cardiomyocytes and mitochondria as well as the content of ROS were increased significantly， while the content of ATP and expression levels of CK protein were decreased significantly （P＜0.05）； there were swelling of endoplasmic reticulum and mitochondria， dissolution or even disappearance of mitochondrial ridge， obvious cardiomyocytes injury. Compared with model group， the expression of ROS in primary hypoxic cardiomyocytes and mitochondria of administration groups， the contents of ROS in primary hypoxic cardiomyocytes of positive control group and Shenfu yixin decoction high-dose group as well as the content of ROS in primary hypoxic cardiomyocytes mitochondria of administration groups were all decreased significantly， while ATP contents in primary hypoxic cardiomyocytes of positive control group and Shenfu yixin decoction high-dose group as well as expression levels of CK protein in primary hypoxic cardiomyocytes of administration groups were all increased significantly （P＜0.05）. The primary hypoxic cardiomyocytes injury was relieved significantly in positive control group and Shenfu yixin decoction high-dose group. CONCLUSIONS： Shenfu yixin decoction can improve primary hypoxic cardiomyocytes， down-regulate the expression of ROS in cardiomyocytes and mitochondria and also improve its energy metabolism.
