Objective To observe the adipose-derived cytokine changes and aggravate cognitive impairment in olanzapine-induced obese rats caused by glucose metabolic disorder.Methods 20 rats fed with ordinary fodder were used as normal control group,olanzapine group of 20 rats fed with olanzapine(1.2 mg · kg-1) and ordinary fodder for 4 weeks.Successfully established experimental model rats induced by olanzapine after 4 weeks.Serum tumor necrosis factor α(TNF-α),interleukins 6 (IL-6) and C-reactive protein (CRP) contents were measured by Elisa.Serum glucose contents were determined by biochemical colorimetric method and blood lipid contents determined with automatic biochemical analyzer.Learning,memory capacity and escape latency were detected with Maze test.Results After administration 4 weeks,the levels of body weight,blood glucose and blood lipid in olanzapine group were higher than those in control group.The serum TNF-α((1.57±0.04) ng/ml),IL-6((127.47±11.38) pg/ml) and CRP ((2.68±0.06) mg/ml) in olanzapine group rised,compared with control group ((0.59±0.03) ng/ml,(96.58± 8.77) pg/ml and (1.86±0.04) mg/ml respectively),the differences were statistically significant(P＜0.05).Electric shocks and escape latency in olanzapine group were higher than those in control group (P＜0.05).The FBS had positive correlation with hs-CRP,IL-6 and TNF-α respectively (r=0.385,0.260,1.280; all P＜0.05).Conclusion Olanzapine can induce metabolic disturbance of blood glucose,blood hpid,and the increase of serum TNF-α,IL-6 and CRP levels in rats.Positive correlation is showed between TNF-of and FBS.Hyperglycemia can promote cell toxicity and leads to cognitive dysfunction in rats.

Bacillus cereus B-04 antagonist to Botrytis cinerea were isolated from samples of tomato soil infected by Botrytis cinerea in Zibo, which are identified through a series of morphological and biochemical characteristics and the sequence of 16SrDNA. Aiming at enhancing the inhibitory effect of this strain, a 4.1kb DNA fragment containing ?-1,3-glucanases gene from pUC1940 was inserted into vector pBE2 and pHY300PLK to construct recombination plasmids, PBE2-glu and pHY300PLK-glu, which were transferred into Bacillus cereus B-04, resulting in a new strain named B-04-glu. Restriction enzyme digestion and ?-1,3-glucanases plate culture confirmed that B-04-glu contained a functional ?-1,3-glucanases gene. Compared to the wild strain B-04, B-04-glu had an increased inhibitory effect against Botrytis cinerea on tomato.

Objective:To investigate the effect of the application of "internet +" disease management based on the AISAS model on the young and middle-aged patients after PCI therapy.Method:A total of 90 young and middle-aged patients hospitalized in cardiological department of the First Affiliated Hospital of University of Science and Technology of China (Anhui Provincial Hospital) were enrolled between June 2018 to October 2019, and they were randomly divided into observation group and control group with 45 cases in each group. Patients in the control group received telephone follow-up while "internet +" disease management based on the AISAS model was applied in the observation group. The drug therapy compliance, acquisition of the disease knowledge, quality of life, anxiety and depression levels, return to workand incidence of cardiovascular events.Results:One year after the intervention, the drug therapy compliance score, disease-related knowledge score, quality of life score, SAS and SDS scores of the observation group were 7.55±1.21, 7.29±1.27, 701.17±74.86, 32.55± 4.31, 34.74±4.16, the scores of patients in the control group were 6.48±1.56, 6.12±1.94, 670.58±65.29, 41.72±4.33, 40.79±4.17. The difference was statistically significant ( t value was 2.066-11.203, P<0.05). The comparison between the return of the patients and the incidence of cardiovascular events in the two groups was statistically significant ( χ2 value was 5.031, 11.275, P<0.05). Conclusion:This management model can increase the knowledge of disease PCI postoperative patients, improve their quality of life, make patients return to society earlier, and promote the improvement of the quality of continuous nursing service.

OBJECTIVETo study the risk factors of male infertility.

METHODCase control study including 94 cases and control group with a ratio of 1 to 1.

RESULTSThe risk factors of male infertility were long time heavy smoking habit (OR = 3.45, 95% CI: 1.95 - 6.10), illegal sexual intercourse (OR = 7.29, 95% CI: 2.54 - 20.89), growing vegetable under plastic in higher temperature (OR = 6.73, 95% CI: 1.91 - 23.69), contact with benzene chemicals (OR = 20.53, 95% CI: 4.67 - 90.25) and having Ureaplasma urealyticum (Uu) infection (OR = 5.55, 95% CI: 2.28 - 13.53).

CONCLUSIONMale infertility was resulted from many factors repeatedly acting on men for long time. In order to prevent male infertility, issues as environmental pollution, occupational protection need to be improved while bad working condition and risky behavior should be changed.

OBJECTIVETo explore the effect of 18-β glycyrrhetinic acid (GA) on the endoplasmic reticulum of nasal epithelial cells in allergic rhinitis (AR) model rats.

METHODSTotally 96 Wistar rats were randomly divided into the blank group, the AR model group, the loratadine group, the GA group, 24 in each group. AR models were established by peritoneally injecting ovalbumin (OVA). Morphological scoring was performed. GA at 21. 6 mg/kg was intragastrically administered to rats in the GA group. Nasal mucosal tissues were taken for electron microscopic examinations at the second, fourth, sixth, and tenth week after drug intervention.

RESULTSThe overlapping score was 2.10 ± 0.45 in the blank group, 5.10 ± 0.56 in the loratadine group, 5.10 ± 0.56 in the AR model group, 5.20 ± 0.78 in the GA group, showing statistical difference when compared with the blank group (P < 0.01). Results under transmission electron microscope showed that the number of the endoplasmic reticulum increased in the AR model group, with obvious cystic dilatation, a lot of vacuole formation, and degranulation. A large number of free ribosomes could be seen in cytoplasm. With persistent allergen exposure, changes mentioned above was progressively aggravated in the endoplasmic reticulum of nasal mucosal epithelium in the AR model group. But the dilation of endoplasmic reticulum, vacuole formation, and degranulation were relieved in the GA group, and got close to those of the blank group.

CONCLUSION18-β GA could improve the expansion, vacuolization, and degranulation of the endoplasmic reticulum of nasal epithelial cells in AR model rats.

This study was purposed to summarize the clinical characteristics and laboratorial data of blastic plasmacytoid dendritic cell neoplasm (BPDCN) in pediatric patients in order to enhance understanding this disease in diagnosis and therapy. A rare case of BPDCN in children was enrolled in this study. The blood routine test, examination of bone marrow cell morphology, histopathology and immunophenotype of the skin lesions were performed and analysed, the single cell suspensions of the biopsied skin mass were detected by flow cytometry. The results showed that tumor cells expressed CD4, CD56, CD43 and CD123, while not expressed CD19, CD20, CD3, CD8, CD13, CD11b and myeloperoxidase (MPO). According to the clinical and laboratorial features and the results from histopathological and immunophenotype examinations, BPDCN was confirmed. It is concluded that BPDCN in children is an extremely rare hematopoietic malignancy with presenting a rapidly and fatally aggressive clinical course. The diagnosis of this disease is mainly based on the clinical presentations, pathologic and immunohistochemical features. BPDCN is a highly aggressive disease, its prognosis is very poor, its pathogenesis remans still unclear. A standard treatment protocol for BPDCN has not yet been established.
