The treatment of systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS) is difficult in ICU. In addition to traditional methods, immunologic therapy has been used recently to treat SIRS and MODS through adjusting inflammatory responses and redressing abnormal responses. This article reviews the progress in treatment of SIRS and MODS,including blocking inflammatory activation, modifying the activation of inflammation, giving gene therapy and combination therapy of TCM and western medicine.

Objective To investigate the correlation between regional cerebral oxygen saturation (rSO2) value and the prognosis of comatose patients in the intensive care unit (ICU).Methods From January 2013 to September 2014, a total of 64 comatose patients admitted in the department of ICU were enrolled.The patients were divided into two groups : consciousness group (n =25) and coma group (n =39).The level of the Glasgow coma scale (GCS), APACHE Ⅱ score and Full Outline of UnResponsiveness score (FOUR) of patients were monitored.The rSO2 was measured by Somanetics INVOS 5100 monitor.Results The differences in levels of FOUR and GCS at admission and GCS at discharge between the two groups were statistically significant (P ＜ 0.05).In the consciousness group, the levels of GCS、 FOUR and rSO2 were higher compared with the coma group (P ＜ 0.05).ROC curve analysis revealed that the areas under the curve of GCS, FOUR and rSO2 for predicting prognosis were 0.823 (0.718-0.928), 0.820 (0.728-0.912) and 0.924 (0.863-0.985) respectively.Conclusions The rSO2 was useful for estimating the prognosis of comatose patients in general ICU.

ObjectiveTo review the etiology and classification of cholangiectasia. MethodThe clinical data of 1098 patients with cholangiectasia treated from January 2000 to December 2009 were retrospectively analyzed. Results For the 1098 patients, 69 patients (6.3％) had congenital choledochal cyst, and 1029 patients (93.7％) had secondary cholangiectasia which were secondary to 22 diseases, The top 5 of the etiological diseases were bile duct stones (366 patients, 33.3 ％), pancreatic head carcinoma (137 patients, 12.5％), peri-ampullary carcinoma (122 patients, 11.1％), cholangiocarcinoma (68 patients,6.2％),and chronic pancreatitis or pancreatic head cyst (62 patients,5.6 ％). ConclusionsCholangiectasia can be divided into two major categories (congenital and secondary). Congenital choledochal cyst accounted for 6.0％, secondary cholangiectasia accounted for 94 ％.The most common etiologies were bile duct stones, pancreatic head carcinoma and peri-ampullar carcinoma.

METHODS: The methylation of p15 gene in 53 cases of non-Hodgkin’s lymphoma was detected by using methylation-specific PCR (MSP) technique. RESULTS: 18.9% (10/53) in NHL were methylation in p15 gene. p15 gene was frequently in high malignant NHL patients (27.3%) compared with in low malignant patients (0%). CONCLUSION: The result suggested that the hypermethylation of p15 may play an important role in non-Hodgkin’s lymphoma.

Objective To evaluate the effects of therapeutic hypothermia on both neurological status and survival rate in patients after cardiac arrest.Methods The data were searched from MEDLINE,PubMed,EMBASE,Cochrane Library,Wanfang database,CNKI and CBM.The randomized and controlled trials were selected for evaluating the main outcomes of neurological status and survival rate in patients after cardiac arrest.Meta-analysis was carried out by using Review Manger 5.0 software.The results were expressed in risk ratio (RR) for dichotomous outcomes data with 95％ confidence intervals (CI),and P ＜ 0.05 was considered to be significant.Results Eight randomized controlled clinical trials with a total of 1 512 patients met our inclusion criteria.The overall risk ratio of favorable neurological status was 1.34 (95％ CI:1.01-1.78,P ＜0.05) and of survival rate was 1.09 (95％ CI:0.98-1.20,P ＞0.05) with therapeutic hypothermia compared with controls,however,when the applications of conventional cooling trials were analyzed,the risk ratio was 1.51 (95％ CI:1.22-1.87,P ＜0.01) and 1.36 (95％CI:1.13 -1.63,P ＜ 0.01),respectively.Conclusions Patients treated with therapeutic hypothermia after cardiac arrest had more favorable neurological status compared with the controls.There was no benefit of therapeutic hypothermia to survival rate identified.Compare with conventional cooling methods,the therapeutic hypothermia could improve neurological status and survival rate in patients after cardiac arrest.

Objective:To investigate the risk factors affecting the prognosis of patients with extremely severe burns.Methods:Totally 46 patients with extremely severe burn in the dust explosion of aluminum powder in Kunshan, Jiangsu province on August 2, 2014 were included in this study. The patients were divided into the survival group and death group according to the prognosis of the patients. The patients' age, sex, burn degree, white blood cell, and lactic acid at admission, lactic acid at 48 h, creatinine, albumin, urine volume, blood calcium, acute physiology and chronic health score system II (APACHE II) and SOFA scores, and 90 d mortality were collected. COX regression analysis was used to analyze the possible relationship between the indicators of the two groups and the prognosis.Results:There were no significant differences in white blood cell at admission, creatinine, albumin, urine volume, SOFA score, and APACHE II score in the survival group compared with those in the death group (all P>0.05) and burn degree, the levels of lactic acid at admission, lactic acid at 48 h and blood calcium were significantly different (all P<0.05). Multivariate regression analysis showed that age, albumin and lactic acid at 48 h were independent predictors of death in patients with severe burn ( P<0.05), and these are independent outcome predictors of patients with severe burns ( P<0.05). Conclusions:Age, albumin level and lactic acid at 48 h are independent risk factors affecting the prognosis of patients with severe burns.

OBJECTIVE: To study the clinical value of polysomnography (PSG) and ApneaGraph (AG200) in the diagnosis evaluation of obstructive sleep apnea hypopnea syndrome (OSAHS). METHOD: From January to December in 2012, 67 OSAHS patients diagnosed by PSG were examined by AG200. The apnea hypopnea index (AHI), hypopnea index (HI), apnea index (AI), the lowest oxygen saturation (LSaO2) was were detected and the results were analyzed statistically. RESULT: Significant differences were observed in AI, AHI, LSaO2 between AG200 and PSG (P < 0.05, respectively). No statistically significant difference was found in HI. The differences in HI between AG200 and PSG were not significant (P > 0.05). AHI, HI and LSaO2 was were significantly correlated between AG200 and PSG (r = 0.870, 0.743, 0.374, 0.716, P < 0.01). CONCLUSION AG200 could not replace PSG but could identify the level of upper airway obstruction.
