Primary hypophysitis includes 3 subtypes:lymphocytic,granulomatous and xanthomatous hypophysitis. The primary hypophysitis has a low morbidity and the final diagnosis is mostly determined based on the pathological findings after operation.Now it is considered as an organ specific autoimmune disease.Its clinical manifestations and imaging features are similar to hypophyseal tumor,but the endocrine and pathologic features are different.Glucocortieoid pulse therapy and surgery are the two methods of treatment.

Aim To explore the concentration range of organic solvent which can both effectively increase solubility of the difficult soluble medicine monomer, and have low toxicity to cells, and to clarify the influence of different concentration of ethanol on curcumol efficacy.Methods Different DMSO and ethanol concentrations were diluted in culture medium and incubated with cells A549, NCI-H460, NCI-H1299, NCI-1650, LTEP-a2 and SPC-A1 for 12 h, 24 h, or 48 h, cell viability was tested by a colorimetric assay with 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide(MTT), and different concentrations of ethanol with/without different concentrations of curcumol were also prepared with culture medium, then incubate with A549 and NCI-H460 cells for 24 h, and cell viability was tested by MTT as well.Results Within 48 h the solution with 0.008(V/V) DMSO or less had no significant effect on the cell A549 compared with control group, for NCI-H1650 the concentration was 0.004(V/V) or less, for NCI-H460 the result turned to be 0.002(V/V) or less, and the solution with DMSO below 0.001(V/V) had significant effect on the three other cells, NCI-H1299, LTEP-a2 and SPC-A1.While within 48 h, the liquor with 0.004(V/V) ethanol or less did not exhibit significant cytotoxic effect on the cell A549, for NCI-H460 and NCI-H1650 the result of ethanol concentration became 0.002(V/V) or less, for NCI-H1299 the data was 0.001(V/V) or less, and the liquor with ethanol below 0.001(V/V) showed significant cytotoxic effect on LTEP-a2and SPC-A1.When the proportion of ethanol in solution was below 0.01, it has no cytotoxic on cell A549 and NCI-H460, and the curcumol solution prepared with this kind of ethanol solution only represented the efficacy of curcumol on the cells.Since the solution with 0.01(V/V) ethanol dissolved the curcumol better, the cell viability changed from about 100% to about 35%.Conclusions Different organic solvent expressed different toxicity to the same cell, and the sensitivity of different cells to one organic solvent is dissimilar.and DMSO could be the optimum solvent for A549 and NCI-H1650, while the optimum solvent of NCI-H1299 is ethanol, for NCI-H460 it could be both and DMSO and ethanol, and DMSO and ethanol is not suitable for LETP-a2, SPC-A1 to be solvent.

Objective To analyze the language structure of nursing records and the application of defined vocabulary in nursing records of community child care,and to explore the possibility of structuralization and standardization of community nursing records by researchers' consulting International Classification of Nursing Practice (ICNP(R)2.0).Methods Convenient sampling method was used.A total of 432 handbooks about child health care were extracted from three community health service centers in Liaoning province.By analyzing the nursing records,the vocabulary was selected,and a coding book was built.Then researchers compared them with ICNP(R)2.0 Chinese version.Results Totally 567 terms were extracted.All phrases in nursing records about community child health care can be classified into three categories and seven shafts,which were nursing phenomenon,nursing action and nursing outcome.Our community nursing records about child health care could not fully meet shaft level of nursing record writing requirements from the International Council of nurses.Only 146 records were labeled as perfect fit with ICNP(R)2.0 terminology,223 records as not fit at all.The difference of different levels of suitability distribution about nursing phenomenon,nursing action and nursing outcome had statistically significant difference.Words of able to adapt and can't adapt about nursing action had larger proportion.Words that can't adapt about nursing phenomenon and nursing outcome had larger proportion.Conclusions There is still certain gap between domestic nursing records and ICNP(R)2.0 terminology.The list of terms from comparison nursing records about community child health care with ICNP(R)2.0 can lay the foundation for nursing language system structure and perfect community nursing record language in our country.

Methods The levels of serum C-reactive protein (CRP),interleukin-6 (IL-6),fasting insulin (Fins),fasting plasma glucose (FPG),blood lipids and blood pressure were measured in 114 patients with CI (CI group). The insulin sensitivity index (ISI) was observed and the correlation between ISI and indexes of inflammation were analysed. The results were compared with 70 patients without CI(control group). Results (1) The levels of serum CRP [(2.73?0.87) mg/L]and IL-6[(0.14?0.03) ng/ml] in CI group were significantly higher and ISI(-4.31?0.53) was significantly lower compared with control group[CRP(1.63?0.93) mg/L,IL-6(0.12?0.03) ng/ml,ISI(-3.92?0.43)] ( all P8.2 mg/L was significantly lower than that in the patients with the CRP≤8.2 mg/L (-4.18?0.54)(P

Objective To investigate the effects of perfluorochemical ( PFC) on in vitro long-term hypothermic heart preservation in rats. Methods Thirty Wistar rats were randomly divided into control group ( Celsior solution), Celsior + O_2 group (Celsior solution plus oxygen) and PFC/Celsior + O_2 group (two-layer method plus oxygen) , with 10 rats in each group. Langendorff model of isolated rat heart was prepared. The isolated heart was preserved at 4 ℃ for 8 h, and hemodynamic parameters, coronary effluent flow, and leakage of creatine kinase ( CK), lactate dehydrogenase ( LDH) and aspartate transaminase (AST) were detected after reperfusion. Besides, the myocardial ultrastructure was also observed. Results Compared with control group and Celsior + O_2 group, the left ventricular developed pressure and ± dp/dt in PFC/ Celsior + O_2 group significantly increased ( P < 0.01), while LDH, CK and AST leakage significantly decreased ( P < 0.01). However, there was no significant difference in the above paramters between Celsior + O_2 group and control group (P>0.05). Compared with control group and Celsior + O_2 group, the impairment of myocardial ultrastructure in PFC/ Celsior + O_2 group after hypothermic preservation was alleviated. Conclusion PFC as a supplementation to oxygen in heart preservation solution could enhance myocardial protection during in vitro long-term hypothermic heart preservation in rats via the improvement of energy metabolism.
