Objective To investigate the frequency of lesions detection in patients with cerebral infarction (CI) with SPECT/CT. To investigate fluctuation of regional cerebral blood flow (rCBF) and its relationship with clinical symptoms. Methods Sixty-seven CI patients without cerebellar lesion were randomly selected. The rCBF in the regions of interest (ROI) was examined by SPECT/CT, which was collected from the frontal lobe, temporal lobe, parietal lobe, occipital lobe, thalamus, basal ganglia and cerebellum. The rCBF index was calculated. The association between fluctuation of rCBF index and clinical symptoms of patients was explored. Results There were 251 positive regions in all viewing regions , the total positive rate was 31.2%. The left side was 38.1%, while the right side was 24.4% (χ2=17.522,P < 0.01). In normal group, there were no statistical difference of average rCBF between two halves (P > 0.05). However, the average rCBF on the left parietal lobe was lower (P < 0.01). The average rCBF in the abnormal group was lower than that in ipsilateral normal group (P < 0.01). The average rCBF index in the abnormal group was higher (P < 0.01). In normal group , the average rCBF on the frontal lobe and parietal lobe was low , but the average rCBF on the thalamus and basal ganglia was high (P < 0.01). In abnormal group, there were no statistical difference in the average rCBF (P >0.05). rCBF≥0.7 is a clinical sign of abnormal ROI. Conclusion 30% of ROI of CI patients have lesions and the positive rate of the left side was higher. The biological rCBF values of all lobes were different. Therefore, rCBF index could be used to reflect whether the ROI is normal. rCBF≥0.7 could be used as a sign to quantitatively assess abnormal ROI in clinical practice.

Objective To investigate the effects of sperm DNA fragmentation (SDF)and sperm morphology on the fertilization and embryo development in ICSI.Methods SDF and sperm morphology were detected in the meanwhile of taking eggs in 1 45 ICSI treatment cycle.On the basis of SDF index (DFI)divided into group A (DFI≤30%)and group B (DFI >30%).According to the normal sperm morphology divided into group C (NMSR≥4%), group D (1 %≤NMSR <4%),group E (NMSR <1 %).According to the sperm DFI and NMSR divided into group F (DFI≤30% and NMSR≥4%)and group G (DFI >30% and NMSR <4%).Statistically analyzed ICSI outcome of research group:fertilization rate,embryo utilization rate,good quality embryo rate,implantation rate and clinical pregnancy rate.Results (1 )The normal fertilization rate,embryos utilization rate,good quality embryo rate,implan-tation rate in group A were significantly higher than those in group B (χ2 =6.96,8.95,5.49,3.92,all P <0.05), but clinical pregnancy rate had no significant difference (χ2 =1 .08,P >0.05).(2)The normal fertilization rate was statistically significant in group C,group D,group E (χ2 =34.5,65.8,11 .8,all P <0.05),but there were no significant differences in embryo utilization rate,good quality embryo rate,implantation rate and clinical pregnancy rate (P >0.05).(3 )The normal fertilization rate,embryo utilization rate,good quality embryo rate,implantation rate and clinical pregnancy rate in group F were significantly higher than those in group G,and normal fertilization rate,embryos utilization rate,good quality embryo rate had statistically significant differences (χ2 =37.5,1 1 .0,4.3,all P <0.05). Conclusion Sperm abnormal morphology has negative effect on fertilization,and the high DNA fragments have negative effects on fertilization and embryo development.

Objective To investigate the treatment outcome of modified intracytoplasmic sperm injection (ICSI)using zona pellucida(ZP)-bound sperm.Methods 82 patients with less,weak,abnormal sperm disease who were conformed to ICSI,were divided into traditional ICSI group and the group of modified ICSI using ZP-bound sperm according to ICSI case number.The results of normal fertilization rate,cleavage rate,high-quality embryo rate, planting rate,clinical pregnancy rate and early abortion rate were compared.Results The women's age,the sterility year,mature egg rate,normal fertilization rate,cleavage rate in the two groups had no statistically significant differ-ences (all P>0.05).The planting rate and clinical pregnancy rate of the observation group (46.6%,63.3%)were higher than those of the control group(38.5%,53.6%),but there were no statistically significant differences(all P>0.05).The using embryo rate and high-quality embryo rate of the observation group (73.9%,51.0%)were signifi-cantly higher than those of control group(65.8%,38.6%),the differences were statistically significant(χ2 =5.84,χ2 =11.6,all P<0.05).Conclusion Modified ICSI using ZP-bound sperm can effectively improve the embryos quality in ICSI.

Objective To study the relationship between ischemic stroke and gene polymorphism of an-giotensin-converting enzyme (ACE), apolipoprotein E (APOE) and methylene tetrahydrofolate reductase (MTHFR) among the population of Zhuang nationality in western Gui. Methods We directly sequenced ACE, APOE and MTHFR genes in 149 cases of ischemic stroke and 109 cases of normal people in western Gui. χ2 test was used to measure the relationship between gene polymorphism and ischemic stroke. Hardy-Weinberg genetic equilibrium test was used to evaluate the reliability of these data. Results In the ischemic stroke group, 62 cases, 22 cases and 65 cases carried II genetype, DD genetype and ID genetype in ACE. χ2 test showed no relationship between ACE gene polymorphism and ischemic stroke. In analysis of the polymorpism of APOE in the ischemic stroke and control group, no relationship between APOE gene polymorphism and ischemic stroke was found by χ2 test. MTFHR gene polymorphism was significantly related with ischemic stroke by χ2 test (P = 0.019). Conclusion Polymorphism of gene MTFHR but neither ACE nor APOE is significantly associated with ischemic stroke.

Objective:To obtain the parameters associated with hematoma morpholoy by finite element analysis(FEA) and investigated their performance on predicting and diagnosis hematoma expansion(HE) in patients with spontaneous intracrebral hemorrhage(SICH).Methods:Patients with SICH who met research criteria were retrospective enrolled between June 2015 and December 2017. Clinical parameters on admission were collected, Perform 2 independent methodology on same patient to analysis the hematoma shape base on computed tomography(CT): Clinical routine method that performed by clinical investigator to identified margin irregularity of hematoma by CT ,and calculated the volume of hematoma by simplify Tada formula(ABC/2);The FEA method performed by FEA investigator and gain the hematoma 3 dimensional morphology and variables, include Volume, Surface area, and The quantity of triangles per square milimet surface(TQOT/mm 2). The HE was defined as volume enlargement of >33% compared with that on addmission. All patients were divided into HE and none HE group ,respectively, ABC/2 and FEA generated thire own HE and none HE group as different volume calcuation. The HE risk factors of ABC/2 and FEA were assessed in univariate and multivariable Logistic regression models. and the risk fators diagnosis value for HE were determined by the receiver operating characteristic(ROC) curves. Results:Total of 127 patients were enrolled, The mean time of symptom onset to hospital admitted was 3.08±1.34 h. There were 34(26.77%) cases HE identifed by ABC/2 and 31(24.41%)by FEA. Althought there are significant different (pearson χ2=53.66, P<0.01) of HE identification between ABC/2 and FEA, the 2 methods has moderate consistency (Kappa=0.65). All patients’ hematoma 3D reconstruction were performed by FEA and general observation show that TQOT/mm 2 most likely correlate to irregularity of hematoma 3D shape. Multivariable Logistic regression models indicated that ICH score( OR=1.79, 95% CI:1.19~2.68)was independent HE risk factor for ABC/2, respectively, TQOT/mm 2≥1.95/mm 2 ( OR=16.99,95% CI:5.98~48.33)and Ultraearly Hematoma Growth,(uHG) ( OR=1.05, 95% CI:1.01~1.09)were independent HE risk factor for FEA. With ROC analysis, both the ICH score of ABC/2 and uHG of FEA have low HE predictive and diagnosis value ,the area under the curve (AUC) were 0.64 and 0.67 respectively. However, TQOT/mm 2 was found to have excellent diagnosis value (AUC:0.9), sensitivity and specificity were 77% and 83% when the cut-off value was 1.95. Panel parameter model (TQOT/mm 2+uHG) was not be found to have a significant higher AUC than single parameter on FEA and the clinical routine parameters panel model (ICH +SB P>180 mmHg on addmission) have a unacceptable AUC(<0.7) as well as single parameters. Conclusions:Hematoma shape could be reconstructed and analysis by FEA and TQOT/mm 2 was likely relevance to hematoma morphology. TQOT/mm 2≥1.95 was indicate to have a better HE predicting and diagnosis value than any other risk factors and clinical parameters panel models in our reaserch.

OBJECTIVETo investigate the association of SNP of CD40 gene and its serum levels with ischemic stroke (IS).

METHODSA total of 202 IS patients from a hospital of Baise city were enrolled in case group from May 2013 to November 2014. At the same time, 109 healthy people who had physical check-ups in the outpatient department at the same hospital were enrolled in the control group. All participants were from Guangxi Zhuang Autonomous Region and unrelated to each other. 3 ml venous blood were collected on the premise of informed consent. The single nucleotide polymorphisms of CD40 gene rs1883832 C/T, rs13040307 C/T, rs752118 C/T and rs3765459 G/A were analyzed using a Snapshot SNP genotyping assays, and the serum levels of CD40 were tested by ELISA. t-test was used to compare the serum levels of CD40 between the case and control group, and the genotypes at different locuses in case group; χ(2) test was used to compare the distribution differences of the CD40 gene locuses in different genotypes and allele between the case group and the control group; alleles was established as independent variables, the occurrence of the IS as dependent variable, and expressed relative risk with OR (95%CI) value.

RESULTSIn the case group, the frequency of CC, CT and TT genotypes in CD40 gene rs1883832 C/T were 21.78% (44/202), 49.51% (100/202) and 28.71% (58/202), respectively, and 33.17% (66/199), 48.74% (97/199), 18.09% (36/199) in the control group, respectively, the differences between the two groups was significant (χ(2)=9.57, P=0.008). The CD40 serum levels were (62.7 ± 24.5) pg/ml in the case group, which was higher than that in the control group (45.3 ± 17.2) pg/ml (t=8.97, P<0.001). The serum levels of TT and CT genotypes in CD40 gene were (65.9 ± 26.3) and (64.3 ± 25.9) pg/ml, respectively, and the differences were significant when comparing with CC genotype (t equaled 5.34 and 5.03, respectively, P<0.001). The risk of developing IS was 1.56 times higher in 1883832 T allele carriers than that in rs1883832 C allele carriers (OR=1.56, 95% CI: 1.18-2.06); Combined genotype analysis displayed that CD40 gene rs1883832 C/T, rs13040307 C/T, rs752118 C/T and rs3765459 G/A polymorphisms showed strong linkage disequilibrium, the case group TCCA haplotype was tested to be associated with a significantly increased risk of IS as compared with that in the control group(OR=2.49; 95%CI: 1.13-5.48).

CONCLUSIONCD40 gene rs1883832 C/T polymorphism and its TCCA haplotype were possibly associated with ischemic stroke, and the susceptibility gene for ischemic stroke may be rs1883832 T allele.

Objective To investigate the role of three-dimensional (3D) reconstruction based parameters of hematoma cavity and encephalocoele in predicting hematoma expansion and hospitalized poor outcome in patients with primary brainstem hemorrhage (PBH). Methods Thirty-two PBH patients met research criterion were enrolled from intensive care unit (ICU) between June 2015 and December 2017. Baseline clinical characteristics, CT images on admission and within 48 h of admission were collected. The 3D reconstruction of hematoma cavity and encephalocoele based on CT images was performed by Mimics10.0, and quantity of triangles per square milimet surface (TQOT/mm2), and hematoma volume (HV) and encephalocoele volume (EV) were obtained. All patients were divided into hematoma expansion group and non-hematoma expansion group according to whether hematoma expansion appeared (hematoma expanded>33％ within 48 h of admission as compared with that on admission), and hospitalized poor outcome group and hospitalized non-poor outcome group according to whether hospitalized poor outcome appeared (modified Rankin scale scores>4 at discharge or hospitalized deaths), respectively. The risk factors of hematoma expansion were investigated by multivariable Logistic regression analysis. Multivariable Cox hazard regression was used to analyze the risk factors of poor outcome; Kaplain-Meier survival curve analysis and Log-rank test were used to compare the differences in survival curves between independent risk factors screened by Cox regression analysis. Results There were 11 patients (34.4％) with hematoma expansion and 14 (43.8％) with ventriculomegaly in 32 patients; in these 11 patients with hematoma expansion, 8 had ventriculomegaly, and the two had positive correlation (rp=0.423, P=0.016). Fifteen patients (46.9％) had poor outcome, in which 11 (34.4％) died in hospital; 5 had hematoma expansion and 8 had ventriculomegaly. Multivariate Logistic regression analysis showed that baseline lactate >2.0 mmol/L (OR=11.986, 95％CI: 1.084-132.552, P=0.043) and TQOT/mm2>2 (OR=10.223, 95％CI: 1.424-73.396, P=0.021) were independent risk factors of hematoma expansion. Baseline HV (HR=1.102, 95％ CI: 1.020-1.143, P=0.002) and EV (HR=3.485, 95％ CI:1.071-11.463, P=0.040) were risk factors of hospitalized poor outcome identified by multivariable Cox analysis. Kaplan-Meier survival analysis showed that the hospitalization days of hospitalized poor outcome were (74.0±10.6) d and (25.5±7.0) d between patients have hematoma expansion Cut-off value of 7 mL, with significant difference (Log-rank: χ2=11.832, P=0.001), and the hospitalization days of hospitalized poor outcome in patients with and without ventriculomegaly were (68.1±9.0) d and (29.9± 8.8) d, respectively, with significant difference (Log-rank: χ2=7.483, P=0.006). Conclusions There is correlation between hematoma expansion and ventriculomegaly; patients with TQOT/mm2>2 might have high risk of hematoma expansion; patients with baseline HV>7 mL and ventriculomegaly would sooner have hospitalized poor outcome.

Objective:To investigate the influences of SCN3A gene polymorphism(c.905A>G/p.N302S and c. 1441C>T/p.L481L) on the efficacy of valproic acid sodium in the treatment of Zhuangzu epilepsies.Methods:Using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP)technique and the way of direct sequence, the SCN3A gene c. 905A>G/p.N302S and c. 1441C>T/p.L481L genotypes in peripheral blood were detected in 244 epileptic patients (85 cases in effective group and 139 cases of ineffective group) in the standardized treatment of valproic acid sodium.The blood concentration of valproic acid sodium was detected by LC-MS.Evaluating the correlation between the genotype and alleles of two groups of patients and the efficacy of valproic acid sodium and analyzing the difference of valproic acid sodium's blood concentration between different genotypes.The linkage disequilibrium of c. 905A>G/p.N302S and c. 1441C>T/p.L481L were analyzed by software SHEsis.Results:The allele and genotype distribution in c. 905A>G/p.N302S loci between effective group(A, G allele: 50.6%, 49.4%, AA, AG, GG genotype: 27.1%, 47.1%, 25.8%) and ineffective group(A, G allele: 37.4%, 62.6%, AA, AG, GG genotype: 16.6%, 41.7%, 41.7%) had statistically significant difference(χ 2=7.501, P=0.006; χ 2=7.907, P=0.019). There was no significant difference in allele and genotype distribution of c. 1441C>T/p.L481L loci between effective group(C, T allele: 47.1%, 52.9%, CC, CT, TT genotype: 23.5%, 47.1%, 29.4%) and ineffective group(C, T allele: 38.8%, 61.2%, CC, CT, TT genotype: 18.7%, 40.3%, 41.0%)(χ 2=2.920, P=0.088; χ 2=3.099, P=0.212). Compared with the AA + AG genotype, the GG genotype at c. 905A>G/p.N302S locus significantly reduced the efficacy of valproic acid sodium ( OR=2.051, 95% CI=1.136-3.703). Compared with genotypes AA+ AG, there were no significant differences in blood concentration of genotype GG of c. 905A>G/p.N302S ( t=3.256, P=0.137). Compared with genotypes CC+ CT, there were no significant differences in blood concentration of genotype TT of c. 1441C>T/p.L481L( t=4.628, P=0.082). c.905A>G/p.N302S and c. 1441C>T/p.L481L were without linkage disequilibrium. Conclusion:These results suggest that the single nucleotide polymorphisms of c. 905A>G/p.N302S in SCN3A genes may play a role in the resistivity of valproic acid sodium in Zhuangzu epilepsies.
