In order to meet the requirements of ultrasound bone density measurement, we designed a sofware based on Visual Studio C+ + 2008. The software includes interface design, acquisition and control, data processing and parameter extraction, data storage and printing. Excellent human-computer interface (HCI) will give users a convenient experience. Auto gain control (AGC) and digital filter can improve the precision effectively. In addition, we can observe waveform clearly in real time. By using USB communication, we can send control commands to the acquisition and get data effectively, which can shorten the measuring time. Then we calculated the speed of sound (SOS) and broadband ultrasound attenuation (BUA). Patients' information can be accessed by using XML document. Finally, the software offers printing function.

Objective To observe the effect of nerve growth factor(NGF)and electro-acupuncture(EA) on learning and memory in rats with cerebral ischemia.Methods An experimental model of cerebral ischemiareperfusion was established in 40 rats,who were then randomly divided into a model group,a sham operated group,a NGF group,an acupuncture group and a NGF plus acupuncture group.Three weeks were allowed for the recovery of the blood-brain barrier lesion caused by ischemia-reperfusion before intravenous injection of NGF(10μg/kg,once daily for 15 days)via the vena caudalis.In the two acupuncture groups,this was administered in combination with EA at the Baihui(DU20)and Yamen(DU15)acupoints(frequency 100 Hz,2 mA,20 min/time,once daily for 15 days).Morris' water maze test was used to assess any changes in spatial learning and memory abilities.Results The ischemic rats showed significant learning and memory disorders compared with the sham-operated group.In the NGF group,the rats' learning and memory abilities did not impmve significantly compared with the model group and the EA group.Significantly better learning was observed in the NGF+EA group compared with the model group,the EA group and the NGF group.Conclusion NGF combined with EA can improve the learning and memory abilities of rats with learning and memory dysfunction caused by cerebral ischemia-repedusion.

OBJECTIVE:To study inhibitory effect of Lycianthes biflora polysaccharide on the proliferation of hepatic stellate HSCs-T6 cells in rats and its mechanism. METHODS:After treated with 0(blank control),50,100,200μg/ml L. biflora polysac-charide for 24 and 48 h,the activity of hepatic stellate HSCs-T6 cells in rats was determined by MTT assay and inhibitory rate of cell proliferation was calculated;the content of Hyp in supernatant was detected by immunohistochemical assay. After 48 h,the ex-pression of cellular α-smooth muscle actin(α-SMA)was measured by immunohistochemical assay;both transforming growth fac-tor β1(TGF-β1)and Smad3 were measured by Western blot assay. RESULTS:Compared to blank control,50,100 and 200 μg/ml L. biflora polysaccharide could inhibit the proliferation of HSCs-T6 cells;cell inhibitory rates were 39.84%-69.31% and 45.16%-82.93% respectively after treated for 24 and 48 h,which were positively associated with time and concentration. The con-tents of Hyp in supernatant were 178.36-93.25 μg/ml and 131.94-68.74 μg/ml respectively after treated with different concentrations of PRP for 24 and 48 h,which were negatively associated with time and concentration. The protein level of TGF-β1 and Smad3 de-creased after treated with L. biflora polysaccharide for 48 h(P<0.01). CONCLUSIONS:L. biflora polysaccharide can inhibit the proliferation of hepatic stellate HSCs-T6 cells in rats,and its mechanism is associated with the inactivation of endogenous TGF-βpathway for reducing collagen production.

Objective To analyze the application value of enhanced depth imaging optical coherence tomography (EDI-OCT) in measuring the lamina cribrosa thickness(LCT) in patients with branch retinal vein occlusion (BRVO).Methods The clinical data of 65 patients with unilateral BRVO treated in our hospital from September 2014 to March 2016 were selected as the observation group.The single healthy eyes of 40 healthy individuals who received physical examination in the hospital during the same period were selected as the control group.The changes of retinal nerve fiber layer (RNFL) thickness,LCT,central corneal thickness,axial length,transverse diameter of optic disc,vertical diameter of optic disc,diopter and extent of visual field defect in the two groups were determined by EDI-OCT.Results There was no significant difference in the central corneal thickness,axial length,transverse diameter of optic disc,vertical diameter of optic disc and diopter between the two groups (all P ＞ 0.05).LCT of different regions of optic disc in the observation group were lower than those in the control group (all P ＜ 0.05).The range of visual field defects in the observation group was larger than that in the control group,and the RNFL thickness was lower than that in the control group (P ＜ 0.05).LCT was positively correlated with the thickness of whole RNFL in patients with BRVO,and was negatively correlated with the visual field defects (P ＜ 0.05).Conclusion EDI-OCT is an effective means for measuring LCT.LCT of patients with glaucoma BRVO is thinner than that of normal healthy people,and LCT is positively correlated with RNFL.thickness,and negatively correlated with visual field defects.

Objective To identify the potential neoplastic risk in gonadal development abnormality with Y chromosome.Methods Inquiries about the illness history were made.Lymphocyte chromosoreal karyotype of peripheral blood Was analyzed.Sex determining region Y gene and relative steroids and enzymes were detected.Gonadal site was examined through medical imaging.Conadal excision Was performed by laparotomy or laparoscopy.Pathological examinations were done on all of the specimens.Results Among 41 cases of androgen insensitive syndrome,spermatogenie cell neoplasm occurred in 1 patient,sertoli cell tumor in 2,and interstitial cell hyperplasia in 5.Among 14 cases of 17a.hydroxylase deficiency(XY)syndrome,one was sertoli eell tumor,and one Was sertoli cell hyperplasia.In 4 cases of XY pure gonadal dysgenesis.one was gonadoblastoma with dysgerminomm One of 16 cases of X0/XY gonadal dysgenesis Was spermatogenic cell neoplasm with agenda cell tumor.Four cases of testes degeneration were all with dysgenetic testes.All of the gonadoblastoma and germ-cell tumor were located in the pelvis.Tumors occurred mostly during 15 years of age to 32 years.Conclusions The gonads of XY pure gonadal dysgenesis has high risks of gonadoblastoma and germ-cell tumor.The older the onset age after puberty. the higher the malignancy risk is.Once diagnosed,bilateral gonads should be excised as soon as possible.

In order to meet the requirements of ultrasound bone density measurement, we proposed a software solution to improve the accuracy and speed of measurement of bone mineral density of the ultrasound bone densitometer. We used a high-speed USB interface chip FT232H, along with a high-speed AD converter chip to calculate speed of sound (SOS), broadband ultrasound attenuation (BUA ) and other bone density parameters in the PC software. This solution improved the accuracy of the measurement data, reduced the measurement time and increased the quality of the displayed image. It is well concluded that the new software can greatly improve the accuracy and transmission speed of bone density measurement data through a high-speed USB interface and a software data processing technology.
