The mechanism of sepsis is complicated,currently the treatment of severe sepsis is still a challenge.When infected,the body would release cytokines and inflammatory mediators,resulting in out of control of inflammatory reaction and disorder of immune system.Furthermore,sepsis and severe sepsis will be developed.The technique of continuous blood purification (CBP)can powerfully clear solute as water,metabolic wastes,toxic substances,cytokines and inflammatory mediators.Now this technique is not only applied in renal disorders,but also widely used in rescue treatment for critically ill patients.Recently,the guide of sepsis recommended CBP as a method of treating severe sepsis.With CBP application in the early stage of children severe sepsis,it can improve function of heart and lung function,renal function,immune function,coagulation function,and etc.CBP is becoming more and more important in the treatment of children severe sepsis.There are some remaining problem to be resolved,and the individaulized treatment for children sepsis is the focus in the future study.

Purpose To observe the effect of Anti-c-myc on the apoptosis of HL60 cells and leukemicpatients' leukocytes. Methods HL60 cells and leukemic patients, leukocytes were treated with anti-c-mycoligomer-5' d(CTT CTC GAG GCA GGA GGG)3'-complementary to the transcriptional initiation of c-mycmRNA. After 10 hours, we detected the apoptosis by several methods: DNA agarose gel electropboresis,ELISA(enzyme- linked immunosorbent assay), Flow Cytometric Analysis, and Accounting the number ofapoptotic cells after stained with Wright' s. Results The apoptosis of HL60 cells were induced by theanti-c-myc oligomer, and the induction of apoptosis was dose-dependent, i. e. more HL60 cells vereapoptotic as we treated them with higher dose of the antisense oligodeoxynucleotides. Furthermore, the antic-myc oligomer also induced the apoptosis of leukemic patients, leukocytes, but had no effect on theapoptosis of normal leukocytes. Conclusions These results imply that we can treat acute myeloidleukemia with the anti-c-myc oligomer through apoptosis-inducing, and it has good specificity. This studyprovides basis for leukemia treatment.

Lung cancer, a malignant cancer with highest death rate, severely threats the people's health. 80% lung carcinomas are non-small cell lung cancer (NSCLC). Recent studies have found that estrogen system has close relationship with the biological behaviors of NSCLC. Meanwhile, the level of estrogen influences the progression of disease and the prognosis of lung cancer patients. As a result, estrogen pathway has become a hot target in NSCLC treatment. This paper reviews the recearch advances of estrogen system in NSCLC treatment.

BACKGROUND:Most of the traumatic brain injury and stroke survivors have foot drop and varus deformity, that need to be treated with ankle-foot orthosis. OBJECTIVE:To investigate the advantages and effect of early application of front-ankle-foot orthosis on the walking function of the patients with hemiplegia after stroke. METHODS:The clinical data of 54 patients with hemiplegia after stroke treated in the Changshu No. 2 People’s Hospital from June 2008 to October 2009 were retrospectively analyzed. The patients treated with front-ankle-foot orthosis were the front group (n=28), and the patients treated with rear-ankle-foot orthosis were the rear group (n=26). Al the patients received 10 m maximum walking speed test, and the recovery of walking function of the patients in two groups were observed daily. RESUTLS AND CONCLUSION:There were no patients exited and dead in the observation period. The activities of daily living Barthel index in the front-ankle-foot orthoses group (60.0±12.9) was significantly higher than that in the rear-ankle-foot orthoses group (59.1±10.9), and there was no significant difference in the activities of daily living Barthel index between two groups (P>0.05). For the 10 m maximum walking speed test, the walking speed of (39.6±11.6) m/min in the front-ankle-foot orthosis group was significantly faster than that of (33.0±12.4) m/min in the rear-ankle-foot orthosis group (P<0.05). Front-ankle-foot orthosis is more appropriate for patients with hemiplegia after stroke to improve the walking speed.

Objective To evaluate the efficacy and safety of fractionated CO2 laser combined with 308-nm excimer laser for the treatment of stable vitiligo.Methods Forty-nine patients with 109 lesions of stable vitiligo were enrolled in this clinical trial.Each of these lesions was equally divided into 2 parts along the longest diameter,which were then assigned into the treatment group and control group respectively.The treatment group were treated with fractionated CO2 laser radiation for 15-20 minutes once every two weeks combined with 308-nm excimer laser radiation twice weekly.The control group were only treated with 308-nm excimer laser radiation twice weekly.Efficacy was evaluated on day 3 after 12 consecutive weeks of treatment.Results After the treatment,the total response rate in the treatment group and control group was 92.7％ (101/109) and 77.1％ (84/109) respectively.The marked response rate in the treatment group and control group was 85.4％ (35/41) and 65.8％ (27/41) respectively for lesions on the face and neck (x2 =4.23,P ＜ 0.05),70.6％ (24/34) and 41.2％ (14/34) respectively for lesions on the trunk (x2 =7.27,P＜ 0.01),64.0％ (16/25) and 36.0％ (9/25) respectively for lesions on the extremities (x2 =3.92,P ＜ 0.05),5/9 and 1/9 respectively for lesions on the dorsal hands (X2 =4.00,P ＜ 0.05).The number of sessions of 308-nm excimer laser therapy required for the marked response of vitiligo in the treatment group and control group was 7.24 ± 1.23 and 10.81 ± 2.01 respectively for lesions on the face and neck (t =9.70,P ＜ 0.05),15.10 ± 2.47 and 18.95 ± 3.45 respectively for lesions on the trunk (t =5.29,P＜ 0.05),17.37 ± 3.84 and 21.06 ± 4.23 respectively for lesions on the extremities (t =3.23,P ＜ 0.05).No severe adverse reactions were observed in any of the patients during the treatment.Conclusion Fractionated CO2 laser combined with 308-nm excimer laser is effective and safe in treating stable vitiligo.

Objective To observe the interferon-γ(IFN-γ),interhukin-2(IL-2)levels of Th1 cytokine and IL-4、IL-10 levels of Th2 cytokine in serum and culture supernatants of splenic cells of the rats in the prevention of experimentaI autoimmune uveoretinitis(EAU)by oral tolerance. Methods 72 Lewis rats were randomly divided into EAU group,oral tolerance group(which including 10 μg、100 μg、1 mg、10 mg of S antigen group respectively)and control group,12 rats in each group.The animal model of EAU was induced by immunization with S antigen(50 μg)and Freund's complete adjuvant.Oral tolerance 10 μg、100μg、1 mg and 10 mg group were fed with 1 ml mixture of 10 μg、100μg、l mg、10 mg S antigen and 1 mg trypsin inhibitor respectively by intuhation,once the other day,totally 7 times,and then induced EAU according to above methods;control group was fed with 1 ml mixture of phosphate buffered saline and 1 mg trypsin inhibitor,once the other day,totally 7 times,and then induced EAU.The clinical manifestation of EAU in the eye were recorded,the eyeballs were enucleated at the peak of EAU,followed by pathological grading.Meanwhile the serum was colleced;splentic cells were separated and cultured to collect the supernatant.Cytokine levels of IFN-γ,IL-2,IL-4 and IL-10 in serum.cultured supernatant of splenic cells were determined by enzyme-linked immunosorbent assay(ELISA). Results Compared with EAU and control group,the levels of IFN-γ and IL-2(Th1 eytokine)in the serum in 100 μg and 1 mg group were decreased while the levels of IL-4 and IL-10(Th2 eytokine)were inereased,the diffefences were statistically significant(F=51.9,68.8,35.7,7.5,P＜0.01).Compared the levels of Th1 and Th2 cytokines in the serum in 10 μg,10 mg group with EAU and control group.the differences were not statistically significant.In 100 gg、1 mg group,the levels of IFN-γ and IL-2(Th1 cytokine)in the culture supernatant of splenic cells were decreased while the Ievels of IL-4 and IL-10(Th2 cytokine)were increased,compared with EAU and control group,the differences were statistically significant(F=57.1,15.6,33.1,167.7,P＜0.01).Compared the levels of Th1 and Th2 eytokine in the culture supernatant of splenic cells in 10 μg、10 mg groups with EAU and control group,the difference are not statistically significant. Conclusions In the process to prevent EAU by oral intake,the levels of IFN-γ and IL-2 (Th1 cytokine)were decrease while the levels of IL-4 and IL-10(Th2 cytokine).Oral administration with tOO high or low dose of the antigen can not prevent EAU as well as the cytokine levels do not change obviously.Cytokines has played an important role in the prevention of EAU.

Objective To observe the efficacy of the anti-tumor necrosis factor-α monoclonal antibody(TNF-α MCAb)in the treatment of experimental autoimmune uveoretinitis(EAU). Methods EAU animal models were induced by interphotoreceptor retinoid-binding protein(IRBP)R16 peptide with immunization.The rats were divided into 2 groups according to the injection times.TNF-α MCAh was administered intravenously on day 6 or 4,6 and 8 post-immunization respectively,and then to observe the clinical expression by slit-lamp microscope.Meanwhile,take the rats which did not accept TNF-α MCAb as conttol group.Delayed type hypersensitivity(DTH)responses were measured on day 13 postimmunization of IRBP R16;the rats were killed on day 14 post-immunization of IRBP R16,and then enucleated the eyes for histopathological examination.To detect the cytokine level of IFN-γ,IL-4 in serum and IFN-γ in aqueous humor by enzyme-liked immunosorbent assay(ELISA)on day 14 postinjection.The hyperplasia responses of antigen specific lymphocyte of draining lymph node cells were detected. Results The TNF-αMCAb group had mitigated ocular inflammation and decreased pathological grades compared with the control group;the IFN-γ concentrations in aqueous humor and serum were decreased,IL-4 was increased in serum;DTH responses were decreased;the hyperplasia responses of draining lymphocytes to IRBP R16 peptide were decreased,all the differences were statistically significant(P＜0.01).The rats accepted TNF-α MCAb thrice had much better curative effect than the rats injected once(P＜0.05). Conclusions Injection of TNF-α MCAb can inhibit ocular inflammation and specific immune cells of EAU remarkably and change the Th1/Th2 balance.Many times injections of TNF-α MCAb were more effective than once.

Objective To investigate the survival rates of main malignant tumors in Nanhui district. Methods Total 5 783 cases, registered as new cases with malignant neoplasm from 2002 to 2004 in Nanhui, were followed up. Data was studied by survival analysis with SPSS 13.0 of life table and Kaplan -Meier. Results The average annual crude incidence of malignant tumors was 267.57 / 100 000, the World standardized incidence rate of 209.98 / 100 000. Cancer Incidence in the top five ranks followed by lung, liver, stomach, colon and esophageal cancer, the incidence was 43.06 / 100 000, 28.65 / 100 000, 26.82 / 100 000, 18.63 / 100 000 and 9.57 / 100 000, respectively. The difference of the survival rates between the top five cancers was remarkable. Survival rates of cancers among males from the lowest to the highest were liver, lung, esophagus, stomach and intestines. Survival rates of cancers among females from the lowest to the highest were of liver, lung, esophagus, stomach, intestines, cervical and breast. The male or female main cancer's relative survival rate droped along with the age rising. Conclusion The survival status was better in the patients with intestine cancers and female patients with breast cancer, but worse in patients with liver, ung and esophageal cancer.
