Objective To detect the double DNA of trisomy 21 syndrome patients by denaturing high-performance liquid chro-matography(DHPLC) in order to rapidly diagnose trisomy 21 syndrome .Methods To amplify DNA fragments of three short tan-dem repeats of D21S111 ,D21S1411 and D21S1412 using corresponding primers .Then DHPLC was introduced to analyze the DNA fragments in the temperature of 50 ℃ .Results DHPLC elution profiles of D21S111 ,D21S1411 and D21S1412 of normal control showed one peak or two peaks with the same altitude .However DHPLC elution profiles of 21 trisomy syndrome patients showed two peaks of different altitudes ,which one′s altitude was twice than another .Conclusion DHPLC is a sensitive ,convenient ,auto-matic and highly-efficient method to diagnose trisomy 21 syndrome and can be widely used in the clinic diagnosis .

Objective To establish Beagle dogs’model of abducens nerves injury and to observe the clinical therapeu?tic effect of electroacupuncture treatment. Methods Twenty-four Beagle dogs were randomly divided into simple crush group (control group) and crush with electrical stimulation group (experimental group). Cisternal segment of the abducens nerve was given a crush injury, then electrodes were implanted to stimulate the abducens nerve and lateral rectus muscle. Distance between the center of the pupil to medial margin of extraocular adjoin was measured from 1 to 12 weeks after opera?tions. Results All procedures used in the study were well tolerated by Beagle dogs. Electrode implantation to stimulate the lateral rectus muscle and the abducens nerve behind of cavemous sinus was successful. There was no statistical significance of the distance between the two groups from 1 to 2 weeks after operations, and the distance was shorter in experimental group than that in control group from 4 to 12 weeks after operations (P<0.01). Conclusion The animal models established to study electroacupuncture treatment of the injured abducens nerves was successful. Electroacupuncture can promote the re?covery of the injured abducens nerves obviously.

Objective To investigate the changes of antibrain-antibody (AB-Ab) in blood serum and the effect of AB-Ab on blood-brain barrier (BBB) and cerebral edema after the traumatic brain injury (TBI) in rabbits.Methods Forty-five New Zealand rabbits were randomly divided into control group (n =5),sham operation group (fenestration only without injury,n =15) and TBI group (severe lateral fluid percussion brain injury,n =15) according to the random number table.Sham and TBI animals were subdivided at postoperative 1,3,7 and 14 days.Level of AB-Ab,BBB permeability and brain water content were determined after operation.Results At each time point,serum AB-Ab level,BBB permeability and brain water content were higher in sham operation group and TBI group than in control group (P ＜0.05).At postoperative 3,7 and 14 days,serum AB-Ab level,BBB permeability and brain water content were higher in TBI group than in sham operation group (P ＜ 0.05).Conclusion Serum level of AB-Ab is significantly increased after TBI along with synchronous changes in BBB permeability and brain water content,indicating that AB-Ab may be associated with the increase of BBB permeability and brain edema.

Objective: To investigate the effect of ophiopogonin D (OP-D) on blood lipids and intestinal flora in ApoE-/- mice fed with high-fat diet (HFD). Methods: A total of 24 male ApoE-/- mice, aged six weeks old, were randomly divided into control group, model group, OP-D group [0.5 mg/(kg∙d)] and simvastatin group [5 mg/(kg∙d)]. Another six male C57BL/6 mice were in blank group. After 12 weeks of HFD, the drugs were given by intragastric administration for 12 weeks. After the end of administration, fresh feces of mice were collected to detect intestinal flora. Serum of mice was separated to detect blood lipid. Liver section staining was prepared to observe the damage. Results: OP-D could reduce the weight gain of mice caused by HFD, inhibit the increase of total cholesterol and triglyceride, improve hepatic steatosis, and regulate intestinal flora imbalance. Conclusion: OP-D may regulate blood lipids and hepatic steatosis by improving intestinal flora imbalance induced by HFD in ApoE-/- mice.

Objective To analyze MRI features of breast intraductal papilloma,to improve the acquaintance of this disease.Methods The preoperative MRI images (T2 WI-SPAIR,DWI,ADC,TIC and MIP)of eight patients with breast intraductal papilloma confirmed by surgery were reviewed retrospectively,which were compared with the postoperative pathology.The morphology,distribution, enhanced methods and signal characteristics of the lesion were summarized.Results Of 8 cases,the lession was dormant,and MRI revealed three patterns:the first type was occult papilloma,which presented distention of ducts and no solid nodule in 3 cases (37.5%);the second type showed tiny nodules in bar-like dilatation of ducts in 3 cases (37.5%);and the third type presented small round nodules scattering distribued in terminal ductules in 2 cases (25%).The maximum diameter of nodular lesions was 0.4-1.0 cm(average 0.7 cm).The lesions on T2 WI-SPAIR showed equal signal intensity or mixed signals with isointensity/hypointensity,and dilatation catheter.enhancement. The ADC and TIC value were various,therefore,diagnosis of the tumor should be combined with morphology and associated symptoms. Conclusion At early stage,the occult focus of breast intraductal papilloma can be sensitively detected and localized on MRI.It reveals that MRI has advantage in showing morphology of lesion and functional imaging,which is of important value in clinical diagnosis and early treatment.

Objective To observe the dynamic change of brain natriuretic peptide (BNP) in plasma of elderly patients with hy-pertensive intracerebral hemorrhage ,and to explore the relationship between BNP levels and cerebral edema .Methods 56 elderly patients with hypertensive intracerebral hemorrhage were recruited and divided into the operation group (n=26) and the non-opera-tion group(n=30) ,25 hypertensive patients were collected as the control group .ELISA was applied to detect the levels of plasma BNP at 6 ,24 ,72 ,168 h after the onset of hypertensive intracerebral hemorrhage .The non-invasion brain edema monitor was utilized to dynamically monitor the cerebral edema degrees .Results The plasma BNP levels in the operation group and the non-operation group at 6 ,24 ,72 ,168 h were higher than those in the control group ,the differences showed statistical difference (P<0 .05) ,but which at 168 h in the operation group was lower than that in the non-operation group ,cerebral edema appeared at 24 h in the two groups ,and reached the peak value at 72 h in the operation group and at68 h in the non-operation group;the changes of plasma BNP levels had positive correlation with cerebral edema degree (r=0 .685 ,P<0 .05) .Conclusion Dynamic monitoring of plasma BNP levels is an effective indicator for early diagnosis and monitoring of acute brain edema in elderly patients with hypertensive in-tracerebral hemorrhage .

Objective To investigate the relationship between the genetic polymorphisms of glutathione S-Transferase M1,T1 and the susceptibility to sporadic colorectal adenocarcinoma(SCRAC) and smoking and alcohol consumption in Chinese Hans.Methods Multiplex polymerase chain reaction (M-PCR) was used in the study of genetic polymorphisms of GSTM 1,T1 gene.Logistic analysis was performed to elucidate the roles of GSTM1,GST1,smoking and alcohol.Results The null GSTM1,T1 genotypes could increase the susceptibility to SCRAC(OR=1.711,95% CI:1.043～2.805;OR=1.734,95% CI:1.057～2.843),but smoking and alcohol consumption made no significant effect on SCRAC(OR=0.584,95% CI:0.356～0.958;OR=0.378.95% CI:0.217～0.657).Further stratification of the SCRAC patients by chnical features showed that there were no relationship between the GST M1,T1 genotype and the age of the SCRAC patients.But the frequency of null GSTM1 genotype was significantly associated with distal colon adenocarcinoma (P=0.021),colorectal adenocarcinoma of Dukes C classification (P=0.003) and poor difierentiation (P=0.020),respectively.The frequency of null GSTF1 genotype was only higher in colorectal adenocarcinoma of Dukes C classification(P=0.041).No relationship was found between the location,the degree of differentiation and the frequency of null GSTF1 genotype(P＞0.05).Furthermore,the frequencies of homozygous deletion in GSTM1,T1 genes were found to be significantly increased in SCRAC patients than those in healthy controls(38.9%VS25.7%.P=0.023).Conclusion The GST genotype is strongly correlated with SCRAC incidence in Chinese Hans.The null GSTM1,T1 genotypes can enhance the genetic susceptibility to SCRAC.while smoking and alcohol consumption have no significant effect on the susceptibility to SCRAC.
