Objective To disscuss and analyze the clinical effects of whole body mild hypothermia on MODS caused by cerebral hemorrhage.Methods One hundred and eighty patients with MODS caused by cerebral hemorrhage during the period of hospitalized from January 2013 to December 2015 in ICU of our hospital were divided into two groups (observation group and control group) randomly,90 cases patients in each group.Patients in control group were treated with conventional treatment intervention,patients in control group were treated with whole body mild hypothermia on the base of conventional treatment intervention,the score of MODS,the ratio of,VO2 and DO2,the time during the period of hospitalized in ICU,the time of mechanical ventilation,epilepsy incidence and mortality,NIHSS score and PADL score of the patients in these two group after treatment were compared.Results After the comparion,the score of MODS and the state of oxygen consumption and oxygen supply of the patients in observation group were better than the patients in control group,there was significant differences,and had statistical significance (P＜0.05);the time during the period of hospitalized in ICU and the time of mechanical ventilation of the patients in observation group were shorter than the patients in control group,there was significant difference,and had statistical significance (P＜0.05);the mortality were reduce significantly of the patients in observation group than the patients in control group,there was significant difference,and had statistical significance (P＜0.05);the epilepsy incidence of the patients in observation group and control has no significant difference,has no statistical significance (P＞0.05);the NIHSS score and PADL score of the patients in observation group were higher than the patients in control group,there was significant difference,and has statistical significance (P＜0.05).Conclusion The clinical effects of whole body mild hypothermia on MODS caused by cerebral hemorrhage have important significance,can effectively improve the balance of multiple organ dysfunction syndrome patients,can delay the progression of multiple organ dysfunction syndrome patients,improve the prognosis,it is worthy of clinical application and promotion.

OBJECTIVETo observe the effect of N-acetylcysteine (NAC) on intestine injury induced by cardiopulmonary bypass (CPB) in rats.

METHODSThirty-two rats were randomly divided into sham-operated group, NAC control group, CPB model group, and CPB plus NAC treatment group (n=8). In the latter two groups, the rats were subjected to CPB for 1 h. The rats received intraperitoneal injections of normal saline or NAC (0.5 g/kg) as appropriate for 3 successive days prior to CPB, and those in CPB plus NAC group were given NAC (100 mg/kg) in CPB prime followed by infusion at 20 mgsol;(kg·h) until the cessation of CPB. Intestinal and blood samples were collected 2 h after CPB for pathological analysis and measurement of intestinal concentrations of malondialdehyde (MDA), tumor necrosis factor (TNF)-α, interlukin (IL)-6 and activity of superoxide dismutase (SOD), glutathione (GSH), and glutathione peroxidase (GSH-Px) and serum levels of diamine oxidase (DAO).

RESULTSEvident oxidative stress and pathological damages of the intestines were observed in rats after CPB. NAC treatment obviously alleviated intestinal damages induced by CPB, decreased the levels of intestinal MDA, TNF-α, IL-6 and serum DAO and increased activity of SOD, GSH, and GSH-Px in the intestines.

CONCLUSIONPerioperative NAC treatment can alleviate intestinal injury induced by CPB in rats by suppressing oxidative stress and inflammatory response.

OBJECTIVE: To report on a case with homozygous deletion of large β gene cluster and its clinical characteristics. METHODS: A total of 71 001 peripheral blood samples were subjected to capillary electrophoresis and conventional testing for common thalassemia mutations. The genotypes of suspected β gene cluster deletions were analyzed by Gap-PCR and multiplex ligation-dependent probe amplification (MLPA). Their hematological characteristics were compared by statistical analysis R software. RESULTS: Eighty-nine cases were detected with Chinese CONCLUSION The carrier rate for large fragment deletions of β gene cluster in Huizhou region is rather high, for which the value of HbF is significantly increased. Attention should be paid to screening and diagnosis of rare genotype to prevent missed diagnosis and/or misdiagnosis.

OBJECTIVETo explore hematological and molecular characteristics of Hemoglobin Q-Thailand in Huizhou area of Guangdong Province.

METHODSA total of 34 977 samples were screened by capillary and agarose gel electrophoresis. Samples suspected with HbQ strips were subjected to blood cell count and DNA sequencing. Twenty three common mutations associated with α- and β-thalassemia were identified by liquid phase chip and diversion hybridization technique.

RESULTSThe carrier rate of Hb Q-Thailand in Huizhou area was 0.13%. Pedigree analysis indicated that the Hb Q-Thailand allele is linked with a leftward single a-globin gene deletion (-α). Hematological index (HGB, MCV, MCH, HbA, HbA, HbQ) of 45 heterozygous carriers of Hb Q-Thailand were (130.25±17.37) g/L, (79.81±4.97) fl, (26.38±1.48) pg, (71.37±5.07)%, (1.65±0.45)%, (26.87±4.95)%, respectively. A statistical difference was also found in their hematological index of HbA and HbA compared with 408 heterozygous carriers of -α mutation (P<0.05).

CONCLUSIONHb Q-Thailand has a high detection rate in Huizhou area. The allele is mainly in a heterozygous status and linked with -α. The Hb Q strip can be detected by hemoglobin electrophoresis. When combined with other types of thalassemia, the heterozygotes will show unique hematological parameters.

Objective To examine whether mild hypothermia can decrease the incidence of multiple organ dysfunction syndrome (MODS) in patients after intracerebral hemorrhage.Methods Forty-eight patients with intracerebral hemorrhage,admitted to our hospital from March 2014 to December 2015,were divided into two groups:one was treated with mild hypothermia,and another was treated with normal methods after the surgery;the incidence of MODS was calculated between the two groups.Serum interleukin-10 (IL-10) levels were measured with enzyme-linked immunosorbent assay and E4 promoter-binding protein 4 (E4BP4) levels were measured with Simple Western in peripheral blood lymphocytes one,two,5,7,14 and 21 d after surgery.Results The incidence of MODS in patients with mild hypothermia treatment was 11.11％ and that in patients with normal treatment was 28.57％,with significant difference (P＜0.05).The IL-10 and E4BP4 levels in patients with mild hypothermia treatment were significantly higher than those in patients with normal treatment (P＜0.05).Conclusion Mild hypothermia can decrease the incidence of MODS in patients after intracerebral hemorrhage,IL-10 has some role,and E4BP4 is associated with release of interleukin-10.
