As the hallmark sequelae of juvenile dermatomyositis(JDM),the calcinosis still bothers approxi-mately one third of the patients,but it was considered a good prognostic sign. Today,however,it is universally acknow-ledged that the calcinosis is instead deemed a marker of the special state and inappropriate treatment for JDM. The treatment of based on disease process,including the biological agents and other immunomodulator,which have been not the radical therapy. However,it is a crucial to alleviate the calcinosis that controlling the long - term chronic inflamma-tion for JDM.

This article mainly discusses the relationship between the active treatment concept of the systemic lupus erythematosus (SLE) and its positive outcome in long-term prognosis,which is the overall prognosis of SLE benefits from the improvement on the liying conditions of patients with lupus nephritis (LN).Although more argumentations are still required in regards to whether to use the different general conclusions of the meta analysis between the childhood-onset SLE (cSLE) and the early adulthood-onset SLE patients at the same age as more proactive induction therapy in early phase,yet the time point for early therapy before clinical symptoms appearing can be determined and thereby positive anticipation can be achieved through keeping the difference between the long-term prognosis of the cSLE and the adult-onset patients as evidences,and making in-depth study on the innate laws of the heterogeneity of cSLE,meanwhile giving biological markers more application which can be highly reliable in reflecting the morbid status,supported by the study outcomes of pharmacogenetics/pharmacogenomics and further optimization of current immunoregulation/immune inhibitors approaches (as evidences required by long-term effects).

It is an important turning point that early diagnosis and prompts initiation of adequate treatment improve the outcomes of primary or secondary hemophagocytic lymphohistiocytosis (HLH) which is a rare life-threatening syndrome.Even though the survival rate of the patients with HLH has been improved because of the immunochemotherapy or targeted immunotherapy based on new findings in the immunopathogenesis and the genetic defects,reducing the mortality will be main challenge for the pediatricians in pediatric intensive care unit.All of the clinical features are significant clues for the diagnosis,including continuing fever,specific liver dysfunction with coagulation abnormalities,pancytopenia,hypertriglyceridemia and hyperferritinemia.Defining patients' natural killer cells status during the different stages of sepsis and autoimmune diseases will be guiding innovative immunointerventions.

The common mucosal immunological system is an important anatomical basis of the allergic disorders.Its function is not only regulated by the susceptibility gene,but also affected the development because of the early life exposure to antibiotics.It is the tangible that early life antibiotic-driven changes in mucosal immune enhance susceptibility to allergic disorders of respiratory system.A holistic approach to study the mucosal immune system as an integrated global organ is imperative for future advances in understanding mucosal immunology and for future treatment of the allergic disorders.This review will be focus on the latest evidence and the mechanisms in driving the lung-gutcross-talk.

Objective To explore the effects of p38 mitogen-activated protein kinase (MAPK) on apoptosis of small intestinal epithelial cells after transplantation in rats. Methods Small intestinal transplantation was performed in SD and Wistar rats. The recipients were divided into three groups: isograft group (Wistar→Wistar group), allograft group (SD→Wistar group) and allograft+cyclosporine A group (SD→Wistar+CsA group). The grafts were harvested on day 1, 3, 5 and 7 after operation. All graft samples were subjected to histological examination. The apoptosis of graft epithelial cells was detected by TUNEL method. p38 MAPK was measured by Western-blotting method and serum TNF-? was determined by ELISA. Results Mild, moderate and severe rejection reaction occurred in the SD→Wistar group, it was showed that the number of apoptotic cells increased with the severity of the rejection reaction by TUNEL. In SD→Wistar group, the numbers of apoptotic cells were significantly higher than those of the other two groups (P0.05). The expression of p38 MAPK and the level of serum TNF-? were positively correlated with apoptosis in small intestinal rejection after transplantation (r=0.875, P

A rapid method for directly determining tryptophan contents in foods and feedstuffs was described. l-5mg dry sample could be completely hydro-lyzed in a teflon tube containing 5N NaOH with 0.5% soluble starch under 145℃ for 4 hours in vacuum (760mmHg). The hydrolysate was then adjusted to neutral with 6N HCL in icebath and diluted by five times with 4M urea solution (pH = 11), and was measured at excitation wavelength 280nm and fluorescence wavelength 368nm. The sensitivity of the method was 5ng /10ml, and the recovery rate of 97-107% were obtained in the range of 1-5 ?g/10ml standard tryptophan. The value of a number of foods and feed-stuffs obtained were in agreement with the literatature values.

The emulsifiers of the ferula oil was shown to suppress markedly the swelling of the hind paw induced by injection of carrageenin and to suppress the increase of vascular permeability induced by intrad-ermal HA or 5-HT in rats. It also showed significant suppressive effects on oedema of rats hind paw induced by CFA.Experimental results indicated that it has inhibiting effect on DTH by SRBC in mice and suppressing on lymphocytes transformation induced by PHA.

OBJECTIVE:To investigate the use of antibiotics in our hospital.METHODS:The data regarding the use of antibiotics retrieved in July 2006 from 184 discharged histories were analyzed retrospectively.RESULTS:The application rate of antibiotics in our hospital reached 77.3%,of which,34.6% were used in combination of two kinds,and 32.6% were used in combination of three kinds.Only 5.9% of the specimens had been sent for pathologic examination.CONCLUSION:The application rate of antibiotics in the inpatients of our hospital as well as the postoperative use of antibiotics were all on the high side,while the rate of specimens sent for pathologic examination was on the low side,therefore,it is urgent to strengthen control on the rational use and standardized management of antibiotics.
