Objective To study the correlation with the infectious situation of Borna disease with the multiple sclerosisof Zunyi region. Methods Established method of the specific CIC and an antibody of Borna were used to detect the PBMC of 7cases of patients with multiple sclerosis and 93 cases of control group.Results In the collected 7 cases of PBMC in patients with multiple sclerosis, detected 2 positive samples of the specific CIC and antibody of Borna with a positive rate of 28.57%(2/7).Meanwhile, positive plasma samples were also detected in healthy control group, and the positive rate was 7.53%(7/93),The antibody positive rate of control group was also 5.38%(5/93).But between the two groups, the difference was no statistically significant.Conclusion Results indicate that the possibility of BDV infection is presented in Zunyi regions.BDV infection is not necessarily associated with multiple sclerosis.

Objective To explore the simplified method by examining the levels of luteinizing hormone(LH),follicle-stimulating hormone(FSH),estradid(E2) and stosterone(T) at different times in the stimutation test of luteinizing hormone-releasing hormone(LHRH).Methods Sixty patients with precocious puberty accepted LHRH stimutation test.The levels of E2,T,FSH,LH before injection and after 30,60,90 minutes were compaired.The levels of stimutation test of LHRH examined with ACS:180 chemiluminesence.Results There were 39 patients in the group of central precocious puberty(CPP).The levels of FSH and LH in CPP group significantly increased after LHRH 30 minutes injection.The ratio of LH/FSH was higher than 1.The peak level of LH was higher than 12 IU/L.There were 21 patients in group of peripheral precocious puberty(PPP).Compared with the results before injection,the levels of LH were similar to the results of 30,60 and 90 minutes after LHRH injection.Compared with the result before injection,the levels of E2 and T were similar to the result of 60 minutes after LHRH injection.The peak levels of LH and FSH in two groups all focused in 30,60 minutes.Conclusions LHRH stimutation test is mainly based on the peak level of LH and the ratio of LH/FSH,the test can be simplified to examine the levels the of LH and FSH before the test and 30,60 minutes after injection as a basis for the clinical diagnosis.

Objective To evaluate the effects of goal-directed fluid therapy on the tissue perfusion of elderly patients undergoing Laparoscopic Radical Cystectomy.Methods Thirty patients aged 60-82 years with ASA physical status Ⅰ or Ⅱ who were presenting for elective laparoscopic radical cystectomy were randomly divided into routine fluid replacement group (group C,n=15) and GDFT group (group G,n=15).Patients in group C received routine fluid replacement.Patients in group G were treated under goal-directed fluid infusion strategy with a target of SVV≤13%,CI≥2.5 L·min-1·m-2 and ScvO2≥73% under the monitoring of PiCCO.The indexes of hemodynamics and tissue perfusion were collected and recorded at 7 time points: before induction of anesthesia (T1),5 minutes after intubation (T2),5 minutes after pneumoperitoneum and change positions (T3),1 hour after pneumoperitoneum (T4),5 minutes after the abdomen was opened (T5),1 hour after the abdomen was opened (T6) and the end of surgery (T7).Results Compared with group C,group G received less fluid.MAP and SVV between two groups were no statistical significance.The CI in group G in time point T4,T6 and T7 was significantly higher than that in group C (P<0.05).The HR in group G in time point T5 and T6 was significantly higher than that in group C (P<0.05).The aLac in group G in time point T4 and T5 was significantly lower than that in group C (P<0.05).Pcv-aCO2,DO2I and O2ERe between the two groups were not statistically different.Postoperative rehabilitation indexes between the two groups were not statistically significant.Conclusion The GDFT guided under SVV,CI and ScvO2 can keep the effective circulatory volume and pressure to ensure the whole body perfusion,reduce aLac and improve microcirculation without affecting the balance of oxygen supply and demand and the postoperative complication.

Objective To measure the level of diamine oxidase (DAO), and observe the intestinal motor and mucosal barrier injury after acute spinal cord injury (SCI) in rats. Methods A total of 45 Sprague-Dawley rats were randomly divided into SCI group (group A, n=15), sham group (group B, n=15) and control group (group C, n=15). SCI model was established with Allen's strike mode (10 g × 25 mm) by striking T10 spinal segment in rats. One day, three days and seven days after SCI, hind limb motor function was assessed with Basso-Beat-tie-Bresnahan (BBB) Scale in each group, the myoelectric slow wave and ileum smooth muscle contractility were measured in rats, ileum tis-sues were tested with HE staining, and the DAO content of serum was tested with ELISA kit. Results One day, three days and seven days af-ter SCI, the BBB score was significantly lower in group A than in groups B and C (P<0.001). One day, three days after SCI, the frequency and amplitude of both slow wave and contractility were lower in group A than in groups B and C (P<0.05);seven days after SCI, there was no significant difference among three groups (P>0.05). Group A showed ileal mucosal edema, lodging, inflammatory cell infiltration, and submucosal gap increase. The Chiu's score of intestinal mucosal injury was higher in group A than in groups B and C (P<0.05), as well as the serum DAO content one day and three days after SCI (P<0.05), and no significant difference was found in the serum DAO content among three groups seven days after SCI (P>0.05). Conclusion Serum DAO content may respond to the intestinal motor function and mu-cosal injury after acute SCI in rats.

Objective To explore the relationship between extraintestinal rotavirus infections and serum MBP levels. Methods Serum MBP levels were measured by double-antibody sandwich enzyme-linked immunosorbent assays (ELISA) in children including extraintestinal rotavirus infections (n = 76) and common rotavirus enteritis ( n = 63 ) during the acute and convalescence phases. A group of healthy children ( n =50) were recruited as control. Results MBP levels were significantly lower in patients with extraintestinal rotavirus infections( 176.35 ± 113.12 ) μg/L in acute phases than those in patients with common rotavirus enteritis (392. 27 ± 128.96) μg/L and healthy control group(676. 25 ± 248. 63) μg/L, and the difference was significant (P ＜0. 001 ). The serum MBP levels in convalescence phases in the group of extraintestinal rotavirus infections( 358.63 ± 106. 54 ) μg/L was lower than those in the group of common rotavirus enteritis (558. 49 ± 173. 24 ) μg/L and the healthy controls, and their difference was significant ( P ＜ 0. 001 ). The MBP levels in the acute phases among pneumonia group, hepatic lesion group, cardiac damage group and central nervous system damage group caused by rotavirus infection were ( 198.24 ± 126.47) μg/L, ( 169.34 ±124. 38) μg/L,( 184. 62 ± 123.64) μg/L, ( 180. 74 ± 126. 86) μg/L, respectively. The difference among those groups was not significant ( P ＞ 0. 05 ). Conclusion Patients with extraintestinal rotavirus infections showed significantly lower MBP levels during acute and convalescence phases than patients with common rotavirus enteritis. But MBP levels showed no significant differences among those groups of patients with different extraintestinal organ damage caused by rotavirus infection. Lower MBP levels may be associated with the increased susceptibility to extraintestinal rotavirus infections.

Acute myeloid leukemia (AML) is a group of diseases with a conspicuous heterogeneity. Following the development of cytogenetics, multiple reproducible chromosome aberrations have been discovered in AML, many of which not only are diagnostic markers for specific AML subtypes but also significant prognostic factors for determining complete remission (CR), relapse risk, and overall survival (OS). However, with the foundation of available chromosome analysis, a large group of acute myeloid leukemia (AML) patients, 40% to 49% of adults and 25% of children had not been found abnormality of chromosome karyotype under microscope. These so-called cytogenetically normal acute myeloid leukemia (CN-AML) patients have usually been classified in an intermediate-risk prognostic category. Nevertheless, the outcome of the CN-AML patients are varied in clinical studies, likely because there exist diverse gene mutations in these patients according to recent researches. Those mutations at the molecular level, on basis of which AML could be further classified, are significantly associated with CN-AML patients and offer potential targets for specific therapeutic studies. The review focuses on research advances abroad in this field including gene mutations suggesting bad prognosis such as FMS-related tyrosine kinase 3 gene mutation, Baalc gene and ETS-related gene hyperexpression, Wilms' tumor gene mutation and other gene mutations as well as gene mutations suggesting good prognosis such as nucleophosmin gene mutation, mixed lineage leukemia-partial tandem duplication, CCAAT/enhancer-binding protein α gene mutation.
