Cadmium is one of the important heavy metal pollutants with strong toxicity and wide distribution. It poses a threat to human health and invertebrates,especially to insects. It has been demonstrated that cadmium can infiltrate into insects through respiration ,food intake and so on. It can affect their development,and even induce apoptosis via oxidative damage. Insects can gradually develop defense mechanisms against cadmium with the help of metallothionein,antioxidant enzymes, excretion and heat shock protein. Toxicity effect varies among different species. This paper reviewsed the effect of cadmium on development,cell apoptosis mechanism and defense mechanism in insects.

Objective To compare the effectiveness of enteral nutritional emulsion (TPF-D) and enteral nutritional emulsion (TP) in patients with chronic wound and diabetes (CWD). Methods Totally 20 CWD patients in Beijing Jishuitan Hospital from June 2008 to June 2010 were enrolled in this study. Enteral nutritional emulsion (TP) was used for the first 5 days ( TP group) and enteral nutritional emulsion (TPF-D) was used for the second 5 days (TPF-D group). Changes of mean amplitude of glycemic excursions (MAGE), insulin dosage, and prealbumin (PA) were compared between TPF-D group and TP group. The adverse effects and post-operational complications were also observed. Results The every-day MAGE was (2. 56 ±0. 35) mmol/L in TPF-D group, which was significantly lower than that in TP group [ (3.23 ± 0. 42) mmol/L] ( P = 0. 01 ). The mean insulin dosage was (9.6 ± 1.7) U in TPF-D group, which was significantly lower than that in TP group [ ( 12. 2 ± 2. 5 ) U ] ( P =0.03 ). The increase of PA showed no significant difference between TPF-D group [ ( 12.7 ± 3. 3) mg/L] and TP group [ ( 13.4 ± 2. 8 ) mg/L ] ( P = 0. 08 ). No enteral nutrition-related adverse effect or post-operation complication was noted. Conclusion Compared with TP, TPF-D is more suitable for the CWD patients.

Objective To study on the changes of the DNT cells and T lymphocyte subtype in children with infectious mononucleosis (IM) and its clinical significance.Methods The flow cytometry (FCM) was used to detected the DNT cells and other T lymphocyte subtype in 48 cases of IM.Results The study showed that DNT cells( 9.39 ± 4.89 )% were greatly increased in comparison with normal controls (NC) (4.26 ± 1.68)% ( P ＜0.01 ).CD4 cells(21.45 ±9.87)% were decreased ( P ＜0.01 ) and CD8 cells increased in comparison with NC (32.43 ± 5.07) % ( P ＜ 0.01 ).Conclusion DNT cells and T lymphocyte subtype can be used to evaluate the immune function of children with infectious mononucleosis (IM) and provide guidance for adoptive immunotherapy.

Objective To detect the changes of serum integrinβ4 level during both exacerbation and clinical remission of asthmatic patients, and observe the correlation between the changes and balance of Th1/Th2,and to explore the relationship between integrinβ4 and the immune function in asthmatic patients.Methods Thirty?five cases patients who were hospitalized in the Seventh People's Hospital of Shenzhen from May 2013 to June 2015 were collected into this study.Serum interleukin?4(IL?4),interferonγ(IFN?γ),and integrinβ4 were measured with ELISA and western?blotting methods during both exacerbation and remission of asthmatic patients. Then the level of IL?4, IFN?γand integrinβ4 of the two groups were compared. Results The level of serum integrinβ4 protein in the remission stage of asthma was significantly higher than that in the acute attack period, and the difference was statistically significant(0.633±0.032 vs. 0.375±0.107,t=3.31,P<0.01).The level of ser?um IFN?γ in the remission stage of asthma was significantly higher than that in the acute attack period,and the difference was statistically significant((49.3±6.4) g/L vs. (16.7±7.2) g/L,t=3.11,P<0.05),and the level of IL?4 was (25.3±3.6) ng/L and (43.7±11.2) ng/L respectively,the difference between the two groups had sta?tistical significance(t=3.23,P<0.05).The serum level of integrinβ4 and IL?4/IFN?γratio were passively corre?lated(the acute attack period:r=0.749,P=0.05;the remission stage of asthma:r=0.745,P=0.015).Conclu?sion The serum level of integrinβ4 is passively related to IL?4/IFN?γ. Integrinβ4 may play an important role between immune function and the development in airway inflammation of asthmatic patients.
