Objective To investigate the diagnostic value of biexponential model of DWI in nontypical hippocampal sclerosis (HS) of the youth.Methods DWI with multiple b values were performed on 75 youths with right temporal lobe epilepsy and 20 healthy youths(control group).There were no abnormalities in hippocampus on conventional MRI.11 of 75 patients were proved right HS by surgery and pathology (HS group).Compare the volume of the right hippocampus and their D,D? and f values in HS group and control group.Results There were statistical differences in D and f values between HS group and control group (Z=-3.08,Z=-2.23,P<0.05). There were no statistical differences in the volume of hippocampus and D? values between two groups (Z=1.77,Z=-0.19,P>0.05). Conclusion When HS does not have typical appearances on conventional MRI,D and f values can provide help from diffusion and the perfusion of microcirculation aspects.

Objective To investigate the relationship of D-dimer(DD) and fibrinogen levels in blood plasma and diabetic nephropathy(DN).Methods According to the results of urinary albumin excretion rate (UAER), 98 cases of type 2 diabetas were divided into simple diabetic mellitus ( SDM), early diabetic nephropathy ( EDN) and clinical diabetic nephropathy (CDN); other 45 healthy persons were employed as control. Plasma levels of DD and the fibrinogen of all groups were examined.Results There was significant difference of DD and fibrinogen levels in all groups as compared with control group (P

Lower urinary tract symptoms due to benign prostatic hyperplasia is of great prevalence among ageing males,and it can markedly affect patients' quality of life.Personalized drug therapy according to genetic characteristics is the ideal choice for this problem.Here we summarized the latest research findings on the associations of gene polymorphisms with drug efficacy and adverse reaction in the treatment of benign prostatic hyperplasia/urinary tract symptoms.

o statistical difference between WMD group and control group (t = 1.83, t = 0. 88, P 0. 05). Conclusion Conventional MRI is able to quantify the brain maturation and prognosis of premature infants using TMS.

Objective To detect the expression of TrkA in the brain of the Wistar rats during the embryonic phase.Methods Adult Wistar rats were fed in one cage.It was E0 day when sepermia were found in vaginal suppository and vaginal smear.The expressions of TrkA in the brain of Wistar rats during various brain regions were observed by immunohistochemistry on E13,E15,E17,E19 and E21 day. Results On E13 day no obvious expression of TrkA was observed in the embryonic brain.The expression of TrkA had an obviously increasing tendency in the cortex of telencephalon from E15 day to E17 day.And on E17 day,the positive rate of the expression of TrkA reached the second peak.While on E19 day,the expression of TrkA had a temporary decreasing.Then on E21 day the expression of TrkA reached the highest peak.The striatum and hippocampus developed later than the telencephalon till E17 day,and the expressions of TrkA during these stages were same as the cerebrum.Conclusion From E15 to E17 day,obvious expressions of TrkA are observed in the embryonic telencephalon,and it accords with embryonic induction.

OBJECTIVE To investigate the infection status and drug resistance of mycoplasma and chlamydia isolated from female genitourinary tract in order to provide reference for doctors′ reasonable use of medicine.METHODS The IST2 kit produced by Bio-Merieux was used to culture the mycoplasma strains and to do drug susceptibility test.The VEDALAB kit was used to detect chlamydia.RESULTS Among 376 suspected patients with nongonococcal urethritis(NGU),the number of the patients infected by Ureaplasma urealyticum(Uu),mixed strains of Uu and Mycoplasma hominis(Mh),and Chlamydia trachomatis(Ct) were 216,35 and 125,respectively.The positive rate was 57.4%,9.3% and 33.3%,respctively.The drug susceptibility test showed that drug resistance rates of the other six antibiotics in mixed infection of Uu and Mh were higher than that in simple infection of Uu except for josamycin,ofloxacin and doxycycline.The sensitivity of doxycycline,josamycin and platenomycin in mycoplasma was the most highest.CONCLUSIONS Infection in female genitourinary tract is mainly due to Uu.We should reasonably choose and use antibiotics according to drug susceptibility.

Objective To determine the contents of lutein,zeaxanthin and ?-carotene in 31 vegetables.Method High performance liquid chromatography method with Develosil C30 column and ultraviolet detector was used to detect lutein,zeaxanthin and ?-carotene at wavelength of 480nm.A gradient elution method with elution A (acetonitrile:methol=75:25) and B (methyl-tert-butyl-ether) was used to separate the carotenoids in both raw and cooked vegetables.Results The retention time of lutein,zeaxanthin and ?-carotene was 10.355,10.732 and 20.789 min respectively.The contents of lutein,zeaxanthin and ?-carotene were linearly related with the peak area.Analysis showed that dark leafy vegetable such as amaranth,Chinese celery leaf,parsley,spinach and pakchoi petiole contained the highest amount of lutein.Zeaxanthin was detected only in dehydrated daylily.There was little or no loss of lutein,zeaxanthin and ?-carotene but an average increase in lutein and ?-carotene in vegetables after cooking.Conclusion Vegetables,especially dark leafy vegetables are major sources of dietary lutein,and ?-carotene.Consuming cooked vegetables tends to increase the intakes of lutein,zeaxanthin and their bioavailability.

Objective To design a pulse wave measurement system based on ZigBee wireless technology. Methods CC2430 controlled by the pulse sensor unit will be collected in pulsatile signal to human superficial artery through analog circuit preprocessing, which could be transformed into digital signal in digital model, and then can be impressed and displayed by control unit to deal with and display, at the same time, data in ZigBee wireless communication data unit is sent to the host computer and these data would be retrieval and playback of medical workers. Results The experiments show that the system is able to acquire the pulse wave of the human body in real-time, at the same time, through the ZigBee wireless network, it can be real-time, secure and reliable communications. Conclusion It is applicable to a wide range of health movement monitoring, monitoring of mobile hospitals and other areas.

Objective To investigate the amide proton transfer (APT) values in basal ganglia of neonatal piglet hypoxicischemic brain injury (HIBI) model using MR APT imaging.Methods Totally 35 healthy neonatal piglets were selected.There were 5 piglets underwent sham-operation in control group and 30 piglets used to established HIBI models in HIBI group.According to the time interval between APT imaging and the establishment of HIBI model,the piglets in HIBI group were divided into 0-＜2 h,2-＜6 h,6-＜12 h,12-＜24 h,24-＜48 h and 48-＜72 h subgroups.APT imaging was performed on all piglets.The APT value of basal ganglia between control group and all the subgroups in HIBI group were compared.Results After HIBI occurred,the APT values immediately decreased in 0-2 h,and then increased gradually.In 24 h after HIBI,the APT values were mainly returned to the level of control group,then continuously increased.The APT value in control group and 0-＜2 h,2 ＜6 h,6 ＜12 h,12-＜24 h,24-＜48 h,48-＜72 h subgroups in HIBI group were 0.52 ± 0.09,-0.35 ± 0.08,-0.02 ± 0.14,0.28± 0.04,0.46 ± 0.11,0.80 ± 0.11,1.24 ± 0.18,respectively.The APT values between control group and each subgroups in HIBI group had significant differences (all P＜0.01) except for 12-＜24 h subgroup (P=0.68).Conclusion The APT value decreased firstly and then increased after HIBI in neonatal piglet.APT imaging can provide a non-invasive molecular MR method to evaluate the pathophysiological changes of HIBI.
