Objective: To evaluate the effects of dietary behaviors on the risk of hypertension, diabetes and cardiovascular diseases. Methods: A total of 12 208 subjects aged 18-60 years old were investigated by questionnaires to collect demographic data, dietary behaviors and lifestyle information, when they did health examination in a tertiary hospital in Beijing from 2014 to 2019. During the observation period of five year, the incidence of hypertension, diabetes and cardiovascular diseases were collected through health examination files every year. The multivariate logistic regression model was employed to analyze the associations of dietary behaviors with hypertension, diabetes and cardiovascular diseases. Results: The study included 6 218 ( 50.93% ) males and 5 990 ( 49.07% ) females. The cumulative incidence rates of hypertension, diabetes and cardiovascular diseases were 7.75%, 2.72% and 3.49%, respectively. The multivariate logistic regression analysis indicated that the high-sodium diet ( OR=1.422, 95%CI: 1.191-1.697 ) , eating fast ( OR=1.457, 95%CI: 1.102-1.974 ), eating more refined grain ( OR=1.251, 95%CI: 1.050-1.490 ) and drinking milk less than once a week ( OR=1.316, 95%CI: 1.022-1.697 ) were risk factors for hypertension. The high-sodium diet ( OR=1.344, 95%CI: 1.048-1.725 ), eating fast ( OR=1.733, 95%CI: 1.046-2.871 ), eating more meat ( OR=1.651,95%CI: 1.263-2.158 ) were risk factors for diabetes. High-sodium diet ( OR=1.501, 95%CI: 1.192-1.889 ) was risk factors for cardiovascular disease. Conclusion The diet with high sodium, more meat and refined grain as well as eating fast can increase the risk of hypertension, diabetes and cardiovascular diseases.

OBJECTIVE: To investigate the clinicopathological features of intestinal diffuse large B-cell lymphoma (DLBCL). METHODS: The clinical features, pathological morphology, immunophenotype, and EBER in situ hybridization of 136 DLBCL patients diagnosed in Jinan People's Hospital Affiliated to Shandong First Medical University from January 2007 to October 2014 were analyzed retrospectively. A total of 136 DLBCL samples were obtained, the DLBCL sites were categorized as: duodenum (n=23), ileocecal region (n=63), other small intestine (n=29), rectum (n=7), and other large intestine (n=14). Survival curves for the DLBCL patients were plotted using the Kaplan-Meier method and judged by the Log-rank test. RESULTS: Patients with DLBCL of the ileocecal region and other small intestine except duodenum were mainly male (P=0.042), and had a higher proportion of limited-stage tumors(P=0.015), and lower International Prognostic Index (IPI) (P=0.001). Patients with DLBCL of ileocecal region had higher incidence of lactate dehydrogenase elevation (P=0.007), and higher incidence of intestinal obstruction or perforation (P<0.001) than those with DLBCL of other regions. The 5-year overall survival and 5-year progression-free survival of patients with DLBCL in ileocecal and other small intestine sites were higher than those in other sites, but the differences were not statistically significant (P=0.135, 0.459). Fifty percent of intestinal DLBCL were germinal center B cell-like (GCB) subtypes. A low-grade B-cell lymphoma was found in 21% of 136 tumor samples. In ileocecal and other small intestinal specimens, the proportion of low-grade B-cell lymphoma was 29%, and the difference was statistically significant(P=0.025). About 16% of 136 DLBCL samples expressed follicular lymphoma while no mucosa-associated lymphoid tissue lymphoma . The Epstein-Barr virus-encoded RNA-1 (EBER1) positive rate of duodenal DLBCL was significantly higher than that of other sites (5/23, 22% vs 2/63, 3%, P=0.001). CONCLUSION The intestinal DLBCL is commonly observed in male, and ileocecal is the most primary site. Patients with DLBCL of the ileocecal region and small intestine except duodenum have low IPI, high proportion of limited-stage tumors, low level of lactate dehydrogenase, high incidence of intestinal obstruction or perforation, and low incidence of inert lymphoma. The EBER1 positive rate of DLBCL in duodenal is higher.

Methods: Employee entered the hospital before 2018 were enrolled in the current study and the position was classified as physicians, nurses, medical technician and administrative staff. Minnesota Multiphasic Personality Inventory (MMPI) was completed by the employee at the time of entering the hospital. Status of job burnout was assessed in 2018 using the Maslach Burnout Inventory-General Survey (MBI-GS) . Results: Physicians have a higher rate of paranoia than others (P<0.05) , and administrative staff and medical technician have a slightly higher score than the other two categories of people (P<0.05) , and administrators lie at a higher rate than others (P<0.05) . Further analysis found that personality traits did not have a significant association with job burnout at the time of entry. Conclusion The administrative and medical staff is slightly more irritable, the administrative staff lying slightly higher score, the staff after the entry of job burnout is not affected by the personality characteristics of the onboarding.

Objective To observe the effect of Kidney-nourishing, Blood-activating, Phlegm-resolving and Resuscitation-inducing Decoction(KBPRD)on the expression of N-methyl-D-aspartate(NMDA)receptor subtype 1,2A,2B(NR1,NR2A,NR2B)in the cochlear spiral ganglion neurons(SGN)of tinnitus rats and to explore its mechanism, thus to provide experimental evidence for the treatment of tinnitus with KBPRD. Methods Sixty rats were randomly divided into normal group,model group,western medicine group,and low-,middle-,and high-dose Chinese medicine groups, 10 rats in each group. Rats were given intraperitoneal injection of sodium salicylate combined with water deprivation to induce tinnitus model. After successful establishment of the model, the rats in low-,middle-,and high-dose Chinese medicine groups were given gastric administration of KBPRD in the dosage of 5.5, 11, 22 g·kg-1·d-1 respectively, the rats in western medicine group were given gastric administration of 5 mg·kg-1·d-1 of carbamazepine,and rats in the model group and normal group were given gastric administration of 2 mL of normal saline,once every day,treatment time covering 8 weeks. The expression levels of NR1,NR2A,and NR2B in the cochlear SGN was detected by immunoblotting and real-time quantitative reverse transcription-polymerase chain reaction(qRT-PCR)after 8 weeks of treatment. Results Compared with the normal group,the expression levels of NR1, NR2A and NR2B in the model group were increased, the difference being significant (P < 0.05). Compared with the model group,the expression of NR1,NR2A and NR2B in low-,middle-,and high-dose Chinese medicine groups were significantly decreased(P<0.05).Conclusion KBPRD is effective on relieving tinnitus of rats, and its mechanism is correlated with lowering the increased expression of NR1,NR2A and NR2B in SGN of tinnitus rats.

OBJECTIVETo explore the curative efficacy of methotrexate(MTX) combined with rituxan for treating patients with primary central nervous system(CNS) lymphoma.

METHODSOne hundred patients with primary CNS lymphoma in our hospital were randomly divided into targeted treatment group(50 cases) and traditional treatment group (50 cases). Targeted treatment group adopted the therapy of high-dose methotrexate combined with rituxan, the traditional treatment group adopted the high-dose methotrexate combined with whole brain radiotherapy. The results of relevant imaging examination, clinical data, imaging, follow-up and the survival time were analysed and compared between these 2 groups.

RESULTSIn the targeted therapy group, there were 33 cases in CR, 9 cases were in stable condition, and 5 cases were in partial response, and 3 cases in the progressive stage. In the group of traditional treatment group, 29 cases reached complete remission, 5 cases were in stable condition, 11 cases were in partial response, and 5 cases were in the progressive stage. In the targeted treatment group and traditional treatment group, the median progression-free survival time was 28 and 11 months, respectively.

CONCLUSIONThe first choice for treatment scheme of PCNSL is high-dose methotrexate chemotherapy combined with whole brain radiotherapy, that showed a certain curative effect, but the adverse reactions are larger, and a big late neuro toxic reaction may occur, while high-dose methotrexate combined PCNSL rituxan treatment shows high curative effect, less adverse reaction and low side effects. This treatment also has a more positive value for the elderly patients with PCNSL.

OBJECTIVE:To observe the effects of Paclitaxel,Cisplatin combined with Recombinant human (Rh) endostatin on the efficacy and related indexes of patients with non-small cell lung cancer(NSCLC). METHODS:78 patients with Ⅲb or ⅣNSCLC were randomly divided into control group(39 cases)and observation group(39 cases). Control group received Paclitaxel injection 135-175 mg/m2,d1,intravenous infusion,once a day+Cisplatin injection 25 mg/m2,3 times a day,d1-3,intravenous infu-sion. Observation group additionally received Rh endostatin injection 15 mg/m2,adding into 500 ml 0.9% Sodium chloride injec-tion by slow intravenous infusion 3-4 h,d1-14,then stopped for 7 d. 21 d was regarded as 1 treatment course,it lasted 6 courses. Clinical efficacy,programmed death ligand-1(PD-L1)level,quality of life(QOL)score before and after treatment,and the inci-dence of adverse reactions in 2 groups were observed. RESULTS:All patients completed 2 courses of chemotherapy. There were 3 patients in observation group and 4 patients in control group quitted the study with uncompleted 6 weeks of chemotherapy due to in-tolerance or adverse reactions. The remission rate in observation group was significantly higher than control group,with statistical significance (P<0.05). Before treatment,there were no significant differences in PD-L1 level and QOL score in 2 groups (P>0.05). After treatment,PD-L1 level and QOL score in 2 groups were significantly lower than before,and observation group was lower than control group,with statistical significance (P<0.05). And there was no significant difference in the incidence of ad-verse reactions in 2 groups (P>0.05). CONCLUSIONS:Paclitaxel,Cisplatin combined with Rh endostatin can improve the short-term efficacy of patients with NSCLC,inhibit PD-L1 expression,improve QOL,and do not increase the incidence of adverse reactions.

BACKGROUNDHemorrhagic shock is usually associated with complicated immune and inflammatory responses, which are sometimes crucial for the prognosis. As regulators of the immune and inflammatory system; proliferation, migration, distribution and activation of myeloid-derived suppressor cells (MDSCs) are intimately linked to the inflammation cascade.

METHODSIn a model of severe hemorrhagic shock, thirty-five rats were randomly divided into control, sham, normal saline resuscitation (NS), hypertonic saline resuscitation (HTS), and hydroxyethyl starch resuscitation (HES), with seven in each group. MDSCs were analyzed by flow cytometric staining of CD11b/c(+)Gra(+) in peripheral blood mononuclear cells (PBMC), spleen cell suspensions, and bone marrow nucleated cells (BMNC). Simultaneously, the expressions of arginase-1 (ARG-1) and inducible nitric oxide synthase (iNOS) mRNA in MDSCs were evaluated by quantitative reverse transcription-polymerase chain reaction (qRT-PCR).

RESULTSIn the early stage after hemorrhagic shock, fluid resuscitation and emergency treatment, the MDSCs in the PBMC of NS, HTS and HES groups markedly increased, and MDSCs in BMNC of these groups decreased accordingly, significantly different to the control group. In hemorrhagic shock rats infused with HTS at the early resuscitation stage, MDSCs in PBMC increased about 2 and 4 folds, and MDSCs in BMNC decreased about 1.3 and 1.6 folds, as compared to the sham group respectively, with statistically significant difference. Furthermore, compared to the NS and HES groups, the MDSCs in PBMC of HTS group increased 1.6 and 1.8 folds with statistically significant differences; the MDSCs decrease in BMNC was not significant. However, there was no statistically significant difference in MDSCs of spleen among the five groups. In addition, compared to the control, sham, NS and HES groups, the ARG-1 and iNOS mRNA of MDSCs in PBMC, spleen and BMNC in the HTS group had the highest level of expression, but no statistically significant differences were noted.

CONCLUSIONSIn this model of rat with severe and controlled hemorrhagic shock, small volume resuscitation with HTS contributes to dramatically early migration and redistribution of MDSCs from bone marrow to peripheral circulation, compared to resuscitation with NS or HES.

To compare the early effects of hypertonic and isotonic saline resuscitation on heme oxygenase-1 (HO-1) expression in organs of rats with hemorrhagic shock. Rats were randomly divided into hypertonic saline resuscitation (HTS), normal saline resuscitation (NS) and sham groups. HO-1 mRNA, protein expression and apoptosis were evaluated in organs. In the HTS group, significant difference was noted in HO-1 protein in small intestinal mucosa and liver compared with the NS and sham groups, and in HO-1 mRNA in liver and kidney compared with the sham group. The apoptosis of small intestinal mucosa, liver, heart, and lung was significantly lower in the HTS group than that in the NS group. In this study, small volume resuscitation with HTS can efficiently up-regulate the expression level of HO-1 in small intestinal mucosa and liver, which may be one of the mechanisms alleviating organ damage.
