Objective·To discusses the high risk factors and therapy strategies for ovarian hyperstimulation syndrome (OHSS). Methods·Seventy-seven cases with moderate and severe OHSS were collected to be retrospectively analyzed in Shanghai Ninth People's Hospital affiliated to Shanghai Jiao Tong University School of Medicine from January 2010 to December 2016. Results·Compared with non-pregnant patients, pregnant patients were more likely to have severe OHSS (P<0.05). Embryo transfer patients who underwent ovulation induction and oocyte retrieval became severe OHSS much more easily and had a much longer hospital stay than oocyte retrieval patients (P<0.05). Pumping ascites and pleural effusion or not has no effect on the length of hospital stay and the usage of low molecular dextran for patients with severe OHSS. Conclusion·The risk of OHSS should be evaluated to determine whether or not to carry out a fresh embryo transfer in patients who underwent ovulation induction and oocyte retrieval. For OHSS patients who have undergone embryo transfer or pregnancy, more attention should be paid to the progress of the disease, and individualized treatment is required.

Objective To explore the correlation of illness uncertainty and coping styles of patients with hepatitis B . Method A total of 254 patients with hepatitis B were assessed by Chinese version of Mishel′s uncertainty in illness scale ( MUIS ) and medical coping modes questionnaire ( MCMQ ) . Results The average score of illness uncertainty was at a higher level . The patients mainly used confrontation coping style. The illness uncertainty was positively correlated with the coping style of acceptance-resignation (P<0.05). Conclusion The illness uncertainty of patients with hepatitis B is at a higher level. Nursing intervention should be taken to reduce the degree of patients′uncertainty in illness and encourage them to take positive coping style.

Immune thrombocytopenia (ITP) is a common bleeding disease in children.Recent advances has indicated that such factors as decreased platelet,fear of bleeding,prognosis,therapy associated side effect and restricted activities,usually decreased quality of life of patients and their parents.This review focuses on domestic and overseas researches on health-related quality of life (HRQoL) in children with ITP,in order to attract more scholars' attention.HRQoL should be recommended as an important indicator in treatment and management of ITP.

Objective To observe the effect of cyanin on the expression of L-glutamate/ L-aspartate transporter (GLAST) in high glucose cultured retina Müller cells. Methods The retinal tissue of SpragueDawley (SD) rats was collected at postnatal 10 day, and Müller cells were isolated and cultured according to literature. The Müller ceils (2nd-4th generations) were treated with five different medium as normal group (group A), high glucose control group (group B), high glucose+30 μmol/L cyanin group (group C), high glucose+60 μmol/L cyanin group (group D) and high glucose+100 μmol/L cyanin group (group E). Cell relative survival rates (A value) were measured by MTT assay at 570 nm. The GLAST protein expression in M011er cells was observed by Western blot. Results MTT assay showed that the A value of the five group were 0. 450 8±0. 020 4, 0. 270 1±0. 031 4, 0. 332 0±0. 023 2, 0. 428 3±0. 017 2, 0. 361 9±0. 027 0,the cell relative survival rate were 100. 0%, 59. 9%, 73.6%, 95%, 80.3% respectively. The A value of group C, D, E were significantly higher than that of group B (F=32.25, P<0.05), the A value of group D were significantly higher than that of group C and E (F=21.07, P<0. 05). Western blot showed that the GLAST protein expression of group B was lower than that of group A (t=5.25, P<0. 05) ; there was no obvious changes of GLAST protein expression in group A, C, D and E (F= 2. 979, P>0.05).Conclusion Cyanin can rescue high glucose-induced GLAST reduction.

AIM: To study the effect of heat shock protein (HSP) on the maturation of dendritic cells (DCs) and observe the morphological changes of DCs dynamically. METHODS: The HSP (gp96)-peptide complex was purified from the tissues of hepatocellular carcinoma. Hepatoma cells were treated by heat shock for preparation of the HSP expressed on cell surface and then marked with DiI fluorescence. Immature DCs from peripheral blood mononuclear cells were cocultured with two types of HSPs. The morphological changes of DCs were observed dynamically and the effects of HSPs on the maturation of DCs analyzed by Flowcytometer. RESULTS: The morphological changes and the processes of antigen capture of DCs cocultured with DiI marked tumor cells were well showed. Four ways to capture antigens of DCs were observed, including direct contact, besieging, forming bubbles and extending pseudopodia with bubbles on the terminals. Results also indicated that both types of HSP could promote the maturation of DCs. CONCLUSION: DiI is a good fluorescent dye suitable for the morphological studies of DCs. Four ways for DCs to capture antigens were indicated in this paper. Different types of HSP, purifed from tumor tissues or expressed on tumor cells surface, promote DC maturation, and the purified HSP is more effective. [

Fusion PCR, which employs chimeric primers to generate PCR products with complementary ends in its amplifications, is a rapid and flexible method in joining different DNA fragments. This method can assemble DNA fragments without the treatment of restriction endonucleases and T4 DNA ligase. It offered a shortcut for the construction of homologous recombinant fragments. Through assembling three recombinant fragments successfully, fusion PCR procedure was improved and manipulation essentials of fusion PCR were described in detail. The results indicated that the improved procedure can assemble three or four fragments simultaneously, and the length of each fusion product is above 4.5 kb. The result recombinants were proposed to be use in further experiments, which structures had been confirmed by sequencing.

Based on a ?-tubulin gene EST sequence from Trichoderma harzianum mycelium cDNA library,a 1.74kb ?-tubulin gene coding region,together with a 1.5kb 5'-flanking region and a 1.0kb 3'-flanking region was cloned from T.harzianum by IPCR methods.The gene encodes a 446 amino acid polypeptide,which shows a high degree of homology with other fungal ?-tubulins.A three-dimensional model of the T.harzianum ?-tubulin was built based on the crystal structure of bovine tubulin using homology modeling method.Tertiary protein structure of the ?-tubulin should provide a basis for understanding a significant body of research on tubulin's properties and interactions with antimicrotubule agents.

Conclusions To assess the fall risk of hospitalized patients in neurology department and implement safety nursing measures among the target patients may be effective in preventing the patients from falling down.

Fine particles,less than 2.5 micrometer in diameter (PM2.5),are the main components of inhalable particles.Because of their relatively small size and large surface area,PM2.5 can absorb and retain chemicals,bacteria,viruses and other toxic substances,penetrate deeply into the respiratory tract and easily reach the alveolar ducts,exerting adverse effects on the lungs.PM2.5 can also be absorbed into the bloodstream through alveolar capillaries,causing serious damage to human health.The biological effects produced by PM2.5 are frequently attributed to the oxidative stress induced by intracellular reactive oxygen species alterations and abnormal release of inflammatory mediators closely involved in the development of lung diseases.This review discusses the research advances in relationships between PM2.5 exposure and inflammatory responses and oxidative stress based on experimental researches,in vivo and in vitro studies.Recent epidemiologic investigations have shown associations between increased incidence of respiratory diseases and lung cancer from exposure to low levels of various forms of respirable fibers and particulate matter.In vivo experiments have disclosed the association between PM2.5 exposure and the exacerbation of asthma,bronchitis,chronic obstructive pulmonary disease,and other lung damages.Cell damage mechanisms mainly include alterations of cell signaling pathways,DNA damage,immune injury,autophagy and apoptosis.
