Aim To further study the protective effects of acutobin on focal cerebral ischemia -reperfusion injury in rats. Methods Reversible middle cerebral artery occlusion (MCAO) models were produced by intraluminal suture technique, and reperfusion was begun 3 hours after occlusion and lasted 24 h. The extent of neurological deficits was evaluated by Longa' method; The cerebrovascular morphology was observed by electron microscope. The infarct area of brain was measured by 2,3,5-triphenyltetrazolium chloride (TTC) staining technique;The 2~4 U?kg~(-1) doses of Acutobin were administrated i.v. at the beginning of ischemia or reperfusion respectively. Results ① After 3-h occlusion and 24 h reperfusion, the neurological syndromes and the infarct area were showed, the change of cerebrovascular morphology were appeared and the ratio of TXB_2/6-Keto-PGF_(1?) in plasma was increased. ② After different doses of acutobin were administrated at different time respectively, the neurological syndromes were alleviated; the infarct areas of brain were diminished; the hurt of cerebrovascular endothelial cell was lessened and the ratios of TXB_2/6-Keto-PGF_(1?) in plasma were reduced. Conclusion Protective effects of acutobin on cerebral ischemia-reperfusion injury in rats may be related to lessening cerebrovascular injury and balancing the ratio of TXB_2/6-Keto-PGF_(1?)

Objective To find the mutation of disease-causing genes of sudden unexplained death syn-drome (SU D S ) in the young by whole exome sequencing in one case. Methods O ne SU D S case was found no obvious fatal pathological changes after conventional autopsy and pathological examination. The whole exome sequencing was performed with the Ion Torrent PGMTM Systemwith hg19 as reference se-quence for sequencing data. The functions of mutations were analyzed by PhyloP, PolyPhen2 and SIFT. A three-step bioinformatics filtering procedure was carried out to identify possible significative single nu-cleotide variation (SN V ), which was missense mutation with allele frequency <1% of myocardial cell. Results Four rare suspicious pathogenic SN V were identified. C ombined with the analysis of convention-al autopsy and pathological examination, the mutation MYOM 2 (8_2054058_G/A ) was assessed as high-risk deleterious mutation by PolyPhen2 and SIFT, respectively. Conclusion Based on the second genera-tion sequencing technology, analysis of whole exome sequencing can be a newmethod for the death cause investigation of SU D S. The gene MYOM2 is a newcandidate SU D S pathogenic gene for mecha-nismresearch.

OBJECTIVETo analyze the Chinese medicine syndrome types of patients undergoing maintenance peritoneal dialysis to provide some clinical reference for the treatment based on syndromes.
METHODSAccording to the criterion made by the Nephropathy Branch of China Association of Chinese Medicine in 2006, the syndrome type of 156 patients were differentiated, and the related laboratory parameters, including serum albumin (ALB), C-reactive protein (CRP), hemoglobin (HB), total urea clearance rate (KT/Vt), residual kidney urea clearance (KT/Vr), blood flow mediated vascular endothelial dilatation (FMD) and volume overload (OH) were measured.
RESULTSSyndrome type presented in patients was different. Along with the progress of dialysis, it changed in the root syndromes from qi-deficiency to yang-deficiency and further to both yin-yang deficiency, while in the superficial syndromes it turned from turbid-damp to blood-stasis. ALB in patients with Pi-shen yang-deficiency type and both yin-yang deficiency type was significantly lower than that in patients with Pi-Shen qi-deficiency type and both qi-yin deficiency type (P < 0.05); KT/Vt in both yin-yang deficiency type was the lowest, significantly lower than that in Gan-Shen yin-deficiency type and both qi-yin deficiency (P < 0.05); OH in Pi-Shen yang-deficiency type and both yin-yang deficiency type was significantly higher than that in other types (P < 0.01). Comparison of patients' age showed that group of patients without superficial syndrome was the youngest and the group of patients with damp-heat syndrome type was the oldest (P < 0.01). CRP in damp-heat type was significantly higher than that in other types (P < 0.05); FMD was lower in blood-stasis type than in turbid-damp type and toxic heat type (P < 0.01); and OH was significantly higher in turbid-damp type than in other types (P < 0.01).
CONCLUSIONSome rules of syndrome type distribution could be seen in patients undergoing peritoneal dialysis, which is related with some laboratory parameters to a certain extent, so may provide a few references for clinical treatment based on syndrome type.

Objective To investigate the expression and significance of B lymphocyte stimulator (Blys) and its receptor BAFF (BAFF-R) in peripheral blood mononuclear cells (PBMCs) from patients with systemic lupus erythematosus (SLE). Methods The expression of Blys and BAFF-R was measured by flow cytometry in 90 pa-tients with SLE,which was compared with that of 45 healthy controls. The relationships between the expression of Blys, BAFF-R and other laboratory parameters as well as disease activity were analyzed. Results The expression of Blys and BAFF-R in PBMCs from patients with SLE was significantly elevated compared to healthy controls (P <0.001), so did the active group (P < 0.001) and inactive group (P < 0.001 and P < 0.01). The expression of Blys in PBMCs from active SLE patients was higher than that of inactive patients (P <0.05). However,there was no statisti-cal difference of BAFF-R between the two groups. The expression of Blys in PBMCs was positively related to SLEDAI (r =0.728,P <0.001) ,IgG and IgM(r=0.691,P<0.001 and r =0.453,P<0.01) ,but negatively related to C3 and CA (r = -0.510, P < 0.001 and r = -0.312, P < 0.05). The expression of Blys in dsDNA positive group was higher than those of dsDNA negative group (P < 0.01). The expression of Blys and BAFF-R in Cl qAb positive group was higher than those of ClqAb negative group as well (P <0.01). Conclusion The expression of Blys and its receptor BAFF-R in PBMCs from SLE is elevated ,which may reflect the disease activity and is related to the pro-duction of autoantibody. They might be involved in the pathogenesis of SLE.

Objective To determine the effect of iron deficiency on hemoglobin A2(HbA2) expression in patients with β-thalassemia.Methods The participants were recruited from the out-patient clinics of the Pediatrics Department and Obstetrics Department of Affiliated Hospital of Guilin Medical College and from some β-thalassemia major families.Blood samples from the participants were used for blood smear tests and hemoglobin electrophoresis and to analyze serum ferritin (SF),3 alpha-globin gene deletions,and 17 beta-globin point mutations.Results Of the 408 individuals,304 were assigned to group A (normal controls),26 to group B (iron deficiency),56 to group C (β-thalassemia),and 22 to group D (β-thalassemia combined with iron deficiency). The results for the comparison of the mean HbA2 values among pairs of groups were as follows: group A vs group B,q=5.074 7,P<0.05; group A vs group C,q=37.650 8,P<0.05; group A vs group D,q=16.043 0,P<0.05;group C vs group D,q=7.682 9,P<0.05; Group B vs group D,q=15.806 6,P<0.05. There were no significant correlation between SF and HbA2 in all 4 groups.Conclusions Iron deficiency decreased the HbA2 level in both controls and individuals with β-thalassemia. HbA2 levels decreased significantly in individuals with both β-thalassemia and iron deficiency as compared with β-thalassemia group alone. However,they remained significantly higher than both the control and iron-deficient groups. Therefore,the elevation of HbA2 could be used to diagnose β-thalassemia reliably even in the presence of iron deficiency.
