The over-activation of phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mechanistic target of rapamcyin (mTOR) pathway is closely related to the occurrence, development and clinical prognosis of malignant tumors. Taking this signal pathway as a target can effectively inhibit tumor progression. At present, the Food and Drug Administration of the United States has approved three drugs (CAL-101, BAY80-6946, IPI-145) for the treatment of recurrent and refractory indolent non-Hodgkin lymphoma, which demonstrates significant efficacy and a manageable safety profile.

Objective To observe the effect of Ginkgo biloba extract (EGb) on intestinal function after spinal cord injury (SCI) in rats. Methods 36 Sprague-Dawley rats were randomly divided into group A (n=12), group B (n=12) and group C (n=12). SCI model was established with Allen's mode (10 g×25 mm) at T10. 30 minutes later, group A was intraperitoneally injected with methylprednisolone 30 mg/kg every 24 hours; group B was injected with Shuxuening injection (EGb) 1.75 mg/kg every 24 hours; group C were injected with equal volume of saline. The slow wave of intestinal smooth muscle was measured, the activity of superoxide dismutase (SOD) and the content of malondialdehyde (MDA) in serum were determined 1 day, 3 days and 7 days after modeling, while intestinal tissue was tested with HE staining. Results The amplitude and frequency of the myoelectric slow wave increased in the groups A and B 3 and 7 days after modeling compared with those in the group C (P<0.05); meanwhile, the activity of SOD increased and content of MDA decreased in the groups A and B (P<0.05). The HE scores decreased in the groups A and B compared with those in the group C (P<0.05), which presented that the inflammatory exudation was mild, the hemorrhagic spot was few and the area was limited. The intestinal villous of the group C was blunt with large infiltration of inflammatory cells and inflammatory exudate on the mucosal surface. Conclusion EGb can improve the recovery of intestinal function in rats spinal cord injury through antioxidant.

Objective:To investigate the prognostic significance of D-dimer level in patients with diffuse large B-cell lymphoma (DLBCL).Methods:The clinical data of 70 newly diagnosed DLBCL patients who were admitted to Tianjin People's Hospital from January 2015 to June 2019 were retrospectively analyzed. The optimal cut-off value of D-dimer for survival was determined according to the receiver operating characteristic (ROC) curve, and the patients were grouped. The differences of coagulation related indexes and clinicopathological features between patients with different D-dimer levels were compared. Kaplan-Meier method was used for univariate analysis of overall survival (OS), and Cox regression model was used for multivariate analysis of OS.Results:According to ROC curve, the best cut-off value of D-dimer for survival was 0.75 mg/L. The proportion of patients with different clinical staging, international prognostic index score, lactate dehydrogenase level had statistically significant differences between the D-dimer ≥0.75 mg/L group (36 cases) and <0.75 mg/L group (34 cases) (all P < 0.05). The prothrombin time of D-dimer ≥ 0.75 mg/L group and < 0.75 mg/L group were (13.5±0.9) s and (13.0±0.8) s, respectively, and the activated partial thromboplastin time were (37±5) s and (34±6) s, respectively,and the differences were statistically significant (all P < 0.05). Univariate analysis showed that the 5-year OS rates of DLBCL patients with Ann Arbor stage Ⅲ-Ⅳ, international prognostic index score > 2, lactate dehydrogenase level > 240 U/L, B symptoms, D-dimer level ≥0.75 mg/L were decreased (all P < 0.05). Multivariate Cox regression analysis showed that D-dimer ≥0.75 mg/L was an independent risk factor for OS of DLBCL patients ( HR=0.368, 95% CI 0.144-0.944, P= 0.038). Conclusion:The level of D-dimer can be used as a clinical indicator to judge the prognosis of DLBCL patients, and the prognosis of patients with high D-dimer level is poor.

Objective: To investigate the current status of HIV-related stigma among college students in Guilin,and to explore the impact of perspective-taking and empathy on HIV-related stigma among college students. Methods: The stratified cluster sampling method was used to select college students from 4 universities in Guilin city. Stratified randomization was used to assign all subjects into a control group (410) and an experimental group (396) for randomized controlled trials,and the HIV-related Stigma Questionnaire and the Basic Empathy Scale were used before and after the intervention. Results: Before the intervention of perspective-taking,there were no statistically significant differences between two groups in subscale scores and total scores of HIV-related stigma (t=0.80，0.35，-0.62，-0.10，P>0.05); However, signiticant differences in subscale scores and total score in HIV-related stigma were found after intervention (t=3.53，2.21，2.30，3.98，P<0.05). There was no statistically singnificant in the scores of all dimensions of empathy level and the total score before the intervention (t=0.10,-0.27,-0.08,P>0.05), dimensional score and total score in empathy were statistically significant after intervention (t=-2.15，-3.06，P<0.05). Empathy played an intermediary role of 14.08% between opinion selection and HIV stigma. Conclusion HIV-related stigma exists among college students in Guilin,and perspective-taking intervention effectively reduces its AIDS stigma. Empathy plays an intermediary role between them.

Objective: To identify the lifestyle pattern of adolescents in Guangzhou and to provide a scientific basis for targeted and individualized interventions for adolescents with different lifestyle pattern. Methods: A survey was conducted by questionnaire among 12 540 students from 27 middle schools in the urban area of Guangzhou using a convenient sampling method. The latent class model (LCM) was used to identify lifestyle patterns of adolescents, and further analyses were conducted to compare differences in dietary habits and willingness to exercise among the different classes. Results: Three lifestyle patterns were identified based on the latent class model: "high sweet snacks/excessive screen time, sleep and exercise deficiency group", 3 797 people, accounting for 30.3%; "low nutrition diet/severe sleep and exercise deficiency group", 2 745 people, accounting for 21.9%; "general diet/sleep and exercise deficiency group", 5 998 people, accounting for 47.8%. Adolescents of different classes had different perceptions of their eating habits and different degrees of willingness to participate in physical exercise, these differences were statistically significant(χ 2=671.54, Z=153.16, P<0.05). Conclusion The results of the latent class model showed that the three classes of adolescents had their own unique characteristics. It is necessary to inform them of their needs, provide guidance and implement targeted interventions according to the unique characteristics of the different lifestyle patterns in empirical work.

At present, there are few treatment protocols with limited efficacy for relapsed and refractory non-Hodgkin lymphoma (NHL). Histone deacetylase inhibitors (HDACi) exert anti-tumor effects by inhibiting the activation of histone deacetylase (HDAC) and regulating gene expression. HDACi alone or combined with other anti-tumor drugs have shown good efficacy in the treatment of relapsed and refractory NHL. This article reviews the progress of HDACi in the treatment of NHL.

OBJECTIVE： To establish a method for simultaneous determination of spinosin and jujuboside A in the seads of Ziziphus jujuba， and to investigate its quality grading standard. METHODS： HPLC-ELSD method was adopted. The separation was carried out on Inertsil ODS-SP column with mobile phase consisted of acetonitrile-water （gradient elution） at the flow rate of 1.0 mL/min. The column temperature was 30 ℃， the temperature of drift tube was 90 ℃， the flow of carrier gas was 2.9 L/min and injection volume was 20 μL. The thickness， width， length and 100-grain quality of the medicinal materials were used as indicators to investigate the appearance traits. SPSS 22.0 software was used to analyze the correlation of the contents of spinosin and jujuboside A， its appearance traits with the quality constant of TCM， and establish a quality classification standard for the seads of Z. jujuba. RESULTS： The linear range of spinosin and jujuboside A were 1.03-6.18 μg/mL （r＝0.999 7）， 1.05-6.30 μg/mL （r＝0.999 8）； the limits of quantitation were 0.171， 0.174 μg/mL， respectively； the limits of detection were 0.052， 0.053 μg/mL， respectively. RSDs of precision， stability and reproducibility tests were all lower 2％. The recoveries were 99.01％-102.97％ （RSD＝1.39％， n＝6）， 97.94％-101.03％ （RSD＝1.13％， n＝6）， respectively. Correlation analysis results showed that the length， width， 100-grain quality spinosin content and jujuboside A content of the medicinal materials were positively correlated with the quality constant of TCM. The results of quality classification for 30 batches of medicinal materials showed that S1-S4 and S7-S12 were first-class products； S5， S6， S13-S17 and S20-S30 were second-class products； S18 and S19 were third-class products. CONCLUSIONS： Established content determination method is simple， precision， accurate and stable， and can be used for simultaneous determination of spinosin and jujuboside A in the seads of Z. jujuba. Established quality grading standard of the seads of Z. jujuba can be used to evaluate the quality.

Objective To investigate the effect of blood group serology and polymerase chain reaction with sequence-specific primers (PCR-SSP) on identification and genotyping of ambiguous ABO blood group. Methods Eighty suspicious ABO blood group samples were identified by serology and polymerase chain reaction with sequence-specific primers (PCR-SSP). The final blood group type and the strategy of the transfusion of each case were determined according to the results of serology and PCR-SSP. Results 40 cases were confirmed to be subtypes, and the remaining 40 cases were normal types with weakened antigens or missing antibodies due to other reasons. The results of molecular genetic blood group typing based on PCR-SSP were 41 cases of subtypes (There were 3 discrepancies between two methods: one was Ael identified by serological methods, while its gene type was O2O2; one was common type O, while its gene type was BO1; one was type A, while its gene type was AB.) and 39 cases of normal ones. Conclusion Genotyping technology combined with serological typing has an important significance in identification of ABO blood groups.

Objective: To explore the patient and hospital related determinants of adherence to early antithrombotic therapy among patients with acute ischemic stroke (AIS). Methods: AIS patients aged 50 years old or above who were eligible for early antithrombotic therapy, were included from the China National Stroke Registry Ⅱ (CNSR Ⅱ) project. Characteristics related to patients and hospitals were collected. Univariate analysis method was conducted to explore the correlation between hospital or patient-related determinants and early antithrombotic therapy. A 2-level logistic regression model was set up to identify patient and hospital-related variables that were associated with the adherence to early antithrombotic therapy, with patient as level 1 and hospital as level 2. Results: A total of 16 910 patients were included in the study, with 14 332 (84.75%) of them having received early antithrombotic therapy. Results from the univariate analysis showed that the patient determinants to early antithrombotic therapy would include age, type of health insurance, average income and history of dyslipidemia. Hospital determinants would include factors as: level and region of the hospital, academic status, with/without stroke unit, quality control on single disease and the percentage of neurological beds in total beds (P<0.05). Data on multilevel model showed that the patient-related determinants on early antithrombotic therapy would include age, gender, average income, history of hypertension, National Institutes of Health Stroke Scale (NIHSS) score at admission while hospital related determinants would include percentage of neurological beds in total beds, and region of the hospital (P<0.05). Conclusions The quality of a hospital was associated with the adherence to early antithrombotic therapy. AIS patients at advanced age or with high NIHSS score at admission should be paid more attention.
