Pleuritis rat model was adopted to observe the influence of Eryngium foetidun L . on in- flammatory cell factors (TNF-a, IL- 6 and NO) . The results showed that Eryngium foetidum L. can decrease the contents of TNF-a , IL- 6 and NO in serum. It is indicated that the anti- inflam- matory effect of Eryngium foetidum L. is probably related to the decrease of the contents of the above factors.

1.The nutrient content of yeast (Condida Y-17) grown on n-alkane studied in this experiment was comparable to that of the same type of yeast produced in other countries. Its content of lead, arsenic, mercury and benzo (a) pyrene were within the limit proposed by the Protein-Calorie Advisory Group of the United Nations System. The Content of its residual n-alkanes and total aromatic hydrocarbons were within or a little over that limit. It is a good supplementary protein feed.2.The corrected PER values were, yeast grown on n-alkane 1.18; deli pid and denucleic acid yeast grown on n-alkane 1.16; brewer's yeast 1.52; full fat soybean meal 1.81. The PER of yeast grown on n-alkane was significantly lower than those of other samples. When 0.3% DL-methionine was added to the diet, the corrected PER values increased: n-alkane grown yeast 2.32; delipid and denucleic acid n-alkane grown yeast 2.49; brewer's yeast 2.35; full fat soybean meal 2.28. The corrected PER value of casein used for correction was 2.43, it was standardized with ANRC reference protein (PER = 2.50).3.Yeast grown on n-alkane with and without removal of lipids and nucleic acid was fed to groups of rats at a dietary level of 25% and 35% respectively for 1 year. A stock diet group and a brewer's yeast diet group were used as control. In the first 3 months the weight gain and feed consumption of the rats fed n-alkanc grown yeast diet were lower than those of the two control groups. The male rats were more sensitive to the change of diet. In the later 9 months the difference of weight gain among different groups were not significant. The concentration of haemoglobin, red cell counts, white cell counts, GPTase activity, serum cholesterol levels and serum urea levels determined at the beginning and the end of the experiment were all in the normal ranges. The concentrations of n-alkanes and odd-chain fatty acids in the adipose tissue of the n-alkane grown yeast group were higher than those of the two control groups, and the difference was highly significant. The concentrations of total aromatic hydrocarbons and benzo(a) pyrene in the muscle of different groups of rats were 0.4-0.6 ppm and 0.4 ppb respectively. No detrimental effect was observed in pathological examination.4.When 5% fish meal or 3.5% casein was added to the 25% n-alkane grown yeast diet, the weight gain and feed consumption of weanling rats were improved significantly, though it was still inferior to those fed with stock diet.5.Strongly growth depressive effect was noted as the level of n-alkane grown yeast was increased to 20% in the diet. This depressive effect was neither due to the toxicity of the residual n-alkanes and aromatic hydrocarbons, nor due to the deficiencies of potassium and selenium in the diet. It might be the result of nutrient or nutrients imbalance of the diet. The appropriate amount of yeast grown on n-alkane used in mixed feed should not be more than 15%.

Objective: Non-suicidal self-injury (NSSI) in adolescents appeared prevalent and multifactorial. This study was to examine the associations between exposure to suicidal behaviors and NSSI in the Chinese adolescents. Methods: Participants included for analyses were 5 154 adolescent students who participated in the baseline survey in 2015 and the first follow-up survey in 2016 of the Shandong Adolescent Behavior and Health Cohort, but with no history of NSSI at the baseline survey. A self-administered structured questionnaire was used to collect data on demographics, behavioral and emotional problems, lifetime and last-year NSSI. Data on the history of exposure to suicide attempt or death of a family member, friend, or close acquaintance were also collected. Multivariate logistic regression methods were used to examine the associations between exposure to suicidal behaviors and NSSI. Results: In the baseline survey, mean age of the 5 154 participants was (14.49±1.48) years, with 48.5% of the participants as girls. Of the participants, 9.0% reported having been exposed to suicidal behaviors, including 6.0% reported to suicide attempt, 4.9% to suicide death, 7.3% to suicidal behaviors of friends/close acquaintances, and 3.1% to suicidal behaviors of relatives. The prevalence rates of NSSI in the last year were significantly higher in adolescents who had been exposed to suicidal behaviors than those who had not (P<0.05). Results from the multivariate logistic regressions showed that exposure to suicide death (OR=1.91, 95%CI: 1.22-3.01) or to suicidal behaviors of relatives (OR=1.79, 95%CI: 1.02-3.12) were both significantly associated with the increased risk of NSSI. Conclusions Experiences related to exposure to suicide-death or suicidal behaviors of relatives were associated with increased risk of NSSI in adolescents. After the suicide events, psychological counseling and health education programs set for high-risk groups were helpful in promoting physical and mental health and preventing the attempt of self-injury in teenagers.

Objective To analyze the therapeutic effect and tolerability of decitabine monotherapy or combined with arsenic trioxide for the treatment of patients with myelodysplastic syndromes (MDS). Methods Clinical characteristics of 32 patients with primary MDS in North Hospital of Ruijin Hospital Affiliated to Medical College of Shanghai Jiaotong University from January 2014 to April 2017 were retrospectively analyzed. The clinical data of these patients were collected, and the patients were followed up. Decitabine combined with arsenic trioxide was used in 23 cases, decitabine (20 mg·m-·2d-1) and arsenic trioxide (0.16 mg/kg) were administrated from day 1 to day 5 and was repeated every 4-6 weeks. For the remaining 9 cases, only decitabine was applied, decitabine(20 mg·m-2·d-1) was administrated from day 1 to day 5 and was repeated every 4-6 weeks. The clinicopathological characteristics and the effect of genetic mutations on the efficacy of treatment were investigated. Results Of the 32 patients with primary MDS, 18 were male and 14 were female. The patients were 17-72 years old with a median age of 56 years old. Genetic analysis revealed 10 cases with TP53 mutations, 8 cases with TET2 mutations, 4 cases with U2AF1 mutations, 3 cases with RUNX1 mutations, 3 cases with ASXL1 mutations, 2 cases with NRAS mutations, 2 cases with DNMT3A mutations and 1 case with JAK2 V617 mutation. The follow﹣up time was 2-23 months with a median follow﹣up time of 8 months. A total of 21 cases (65.6%) attained treatment response. Among them, there were 10 cases (31.3%) with complete remission (CR), 5 cases (15.6%) with bone marrow complete remission (MCR), and 6 cases (18.7%) with hematological improvement. There was no significant difference in the efficiency and CR rate between the combination group and the monotherapy group (P＝0.441, P＝0.681). Ten cases were found to have TP53 mutations, of which 7 cases had CR. Multivariate analysis demonstrated that TP53 mutation was an independent risk factor for CR (P＝ 0.037). All patients developed myelosuppression after treatment, of which 16 cases developed pulmonary infection. Conclusions Decitabine combined with arsenic trioxide in the treatment of MDS is effective and well tolerated. The therapeutic effects of decitabine monotherapy or decitabine combined with arsenic trioxide for treatment of patients with TP53 mutations are better than the average levels.

Objective To quantify the setup errors for the different anatomical sites of patients who received intensity-modulated radiotherapy (IMRT) with linear accelerator on-board kilovolt fan beam CT(kV-FBCT) as non-isocenter IGRT and megavolt cone beam CT (MV-CBCT) as isocenter IGRT. Methods A retrospective analysis was performedon 70 patients who underwent radiotherapy, kV-FBCT, and/or MV-CBCT scans after each routine setup prior to IMRT. The average displacement (M), systematic error (Σ), and random error (б) at different treatment sites in the left-right, anterior-posterior, and cranial-caudal directions were calculated according to the individual displacements. The formula 2.5Σ+0.7б was used to estimate the PTV margin in respective direction. For each single patient, the root mean square in three directions was used as 3D displacement. Results A total of 1130 displacements were recorded in the 70 patients. The PTV margin was estimated to be 1.9-3.1 mm in head and neck cancer, 2.8-5.1 mm in thoracic cancer, 4.6-5.1 mm in breast cancer, 3.0-5.5 mm in upper abdominal cancer, and 3.5-6.8 mm in pelvic tumor. For the 3D mean displacements, the head and neck, thoracic, breast, upper abdominal, and pelvic cancer were 2.4±1.0, 4.0±1.6, 4.1±2.0, 4.6±2.1, and 4.6±2.1 mm, respectively. The average 3D displacement obtained by kV-FBCT and MV-CBCT were 4.1 and 3.4 mm, respectively (P=0.212). Conclusion The quantitative setup-error data can be obtained using linear accelerator on-board FBCT, and the non-isocenter IGRT induced set-up error cannot be negligible.

Transketolase(TKT)is an important enzyme that catalyzes the non-oxidative phase group transfer reac-tion of pentose phosphate pathway(PPP),and is involved in the metabolism of various energy substances in the body,such as glucose,ribose,nucleotides and lipids.TKT can reduce oxidative stress,inflammation,atheroscle-rosis,endothelial dysfunction and Tau protein phosphorylation by inhibiting advanced glycated end-produces(AGEs)produced by non-enzymatic glycosylation(NEG)of proteins and lipids in a high-glucose environment im-proving blood glucose,glucose tolerance and β cell function so to prevent and treat diabetes and its complications.This article reviews research progress on the mechanism of TKT in the treatment of diabetes mellitus and its compli-cations.

Dental resin materials have been widely used in the treatment of dental defects. However, the polymerization shrinkage of the resin materials tends to cause microleakage and accumulation of bacterial plaque, which leads to secondary dental caries. Endowing dental resin with antibacterial properties is an important way to solve this problem. Adding antibacterial agents to dental resin is the main method to give it antibacterial properties. Antimicrobial agents are mainly divided into three types: release type, non-release type and mixed type. In terms of antibacterial effects, the selection and addition of antibacterial agents will affect the antibacterial and mechanical properties of dental resin materials; and the long-term antibacterial effect of antimicrobial agents in the oral cavity remains to be verified; as antimicrobial agents or other environmental factors can lead to drug resistance and even dormant persistent bacteria. In recent years, researchers have been committed to improving the antibacterial effect by modifying antibacterial agents. The sustained release of antimicrobial agents via carriers is also the main research direction. This paper reviews the research progress on the antibacterial properties of dental resin materials.

POEMS syndrome is a rare paraneoplastic disorder. A 60-year-old female patient was admitted to the Department of Gastroenterology, Xiangya Hospital of Central South University (Changsha, China), complaining of abdominal distension, severe edema of both lower limbs and shortness of breath for more than 1 year. After intensive and careful medical investigations, the patient manifested with polyneuropathy, M-proteinemia, splenomegaly, lymphadenopathy, hypothyroidism, extravascular volume overload, sclerotic bone lesions, elevated VEGF and pulmonary hypertension. According to the latest diagnostic criteria of POEMS syndrome, this patient met two mandatory major criteria, two other major criteria and three minor criteria, the diagnosis was clear after ruling out differential diagnosis. The patient was treated with dexamethasone and lenalidomide, which relieved her clinical symptoms. The pathogenesis of POEMS syndrome is not fully understood; however, increased levels of vascular endothelial growth factor may contribute to most of the clinical manifestations. This patient had been in physical discomfort for more than 14 months, which seriously affected her quality of life. Clinically, the awareness of early diagnosis and treatment of POEMS syndrome should be improved.
