Objective To study the clinical value of extensively whey protein hydrolyzed formula and partially whey protein hydrolyzed formula as an adjunctive therapy in treating infantile eczema.Methods Totally 59 bottle-feeding babies with infantile eczema were divided into three groups depending on different formula feeding:extensively hydrolyzed formula feeding group (eHF group,n =18),partially hydrolyzed formula feeding group (pHF group,n =22),and conventional cow's milk formula feeding group (CMF group,n =19).Meanwhile,all patients received the same drug treatment.The effective rate and remission rate were evaluated using the SCORing Atopic Dermatitis (SCORAD) index.Results After 2 weeks of treatment,the effective rate was 38.9％ and the remission rate was 50.0％ in the eHF group,which were significantly different from those in the CMF group (5.3％ and 31.6％) (x2 =12.225,P =0.002).The effective rate was 9.1％ and the remission rate was 40.9％ in the pHF group,showing no significant difference when compared with the CMF group (x2 =0.761,P =0.683).After 8 weeks of treatment,the effective rate was 55.6％ and the remission rate was 38.9％ in the eHF group,comparing to 15.8％ and 47.4％ in the CMF group,the difference was statistically significant (x2 =8.498,P =0.014).The effective rate was 31.8 ％ and the remission rate was 59.1％ in the pHF group,a trend towards higher than that of the CMF group,but the difference was not statistically significant (x2 =4.912,P =0.086).Before (F =0.773,P =0.466) and after (F =1.313,P =0.277) the treatment,the growth and development data in different groups showed no significance differences.Conclusion Both the extensively and partially whey protein hydrolyzed formula play an adjunctive role in treating infantile eczema,although the treatment effectiveness of the extensively hydrolyzed formula appears earlier than that of the partially hydrolyzed formula.

Systemic inflammatory response syndrome (SIRS) and its lethal sequela multiple organ dysfunction syndrome (MODS) are common complications in critical illness, such as severe trauma, shock, infection and major operations. During the past three decades, the evolution in our understanding of SIRS and/or MODS could be divided into three stages. Particularly in recent years, advances in molecular and cellular biology have provided new insights in the pathogenesis of this complex condition. The earlier emphasis on the pro inflammatory mediators involved in propagation of inflammatory response, has gradually been replaced by a realization that SIRS/MODS are the result of an imbalance of pro and anti inflammatory mediators to create the final status of excessive inflammation or immunoparalysis'. Though prognosis remains poor, the knowledge that now exists about SIRS/MODS gives great hope for the future. Progress has been made in new treatment modalities and re evaluation of current available measures. Nevertheless, improved techniques to monitor immunological or other markers of inflammatory and host defense responses will be important in assessing the effects of future therapies on central mechanisms contributing to SIRS/MODS.

For uncontrolled hemorrhagic shock the traditional method and target of resuscitation may be harmful. The existing data supported a strategy of less aggressive interventions to those shock with uncontrolled hemorrhage until a decisive surgery begin. The choice of liquor for resuscitation remains in controversy. A combined application of crystalloid and colloid liquor seems to be reasonable and may be accepted by most physicians. It should be noted that the new resuscitation strategy may not be suitable to some kinds of trauma, such as traumatic brain injury, and its long-term effects on to the prognosis should be further evaluated.

Objective To detect the changes of interleukin-18 (IL-18) in plasma of trauma patients and evaluate their value in early warning of organ dysfunction. Methods A prospective study was carried out in 54 trauma patients admitted in from March 2001 to September 2002, which were divided into low injury severity score(ISS) group (Group L-ISS) and high ISS group (Group H-ISS). ELISA was applied to measure the level of IL-18 of blood samples that were collected on arrival, at days 4, 7 and 14 following admission. In the meantime, IL-18 level of plasma samples from patients with systemic inflammatory response syndrome (SIRS), sepsis and multiorgan dysfunction syndrome (MODS) was retrospectively analyzed so as to calculate the critical value of IL-18 in predicting organ dysfunction. Results After trauma, IL-18 concentration of plasma reached peak at days 4 and 7, and decreased gradually at day 14, which was significantly related to SIRS, sepsis and MODS, respectively. The IL-18 level was high relatively in plasma from patients with organ dysfunction. The higher IL-18 level in plasma within seven days after trauma indicated the severer organ dysfunction. Conclusion IL-18 is sensitive in early warning of organ dysfunction after trauma.

OBJECTIVETo evaluate the therapeutic effect of ulinastatin combined with thymosin α1 in the treatment of severe sepsis in rats.

METHODSNormal Wistar rats were subject to cecal ligation and puncture (CLP) to establish models of severe sepsis. The rats were then randomized into 4 groups for treatment with saline (control), ulinastatin, thymosin α1, or the combination of the latter two injected through the caudal vein or subcutaneously at 6, 24, 48 and 72 h after modeling. The mortality rate was recorded daily and the rats were executed at 24, 48, 72 and 96 h after CLP to harvest the heart, liver, spleen, lung, kidney and small intestines for pathological examination. The spleen of the rats were taken for detection of apoptosis of the spleen cells.

RESULTSThe mortality rate of the septic rats in the combined treatment group was decreased significantly (P=0.0325). The control group showed the most severe organ damage, which was moderate in single drug treatment group and the mildest in combined treatment group. Obvious spleen cell apoptosis was found in the control group, and was significantly ameliorated in the combined treatment group[(47.4∓10.9)% vs (39.3∓11.4)%, P=0.0000].

CONCLUSIONCombined treatment with ulinastatin and thymosin α1 can significantly improve the prognosis and ameliorate organ damage and spleen cell apoptosis in rats with sever sepsis.
