Objective To evaluate the value of magnetic resonance spectroscopy (MRS) in the diagnosis of prostate cancer and benign prostate hyperplasia. Methods Fifty-five patients including 36 benign prostate hyperplasia patients and 19 prostate cancer patients,were performed with the scanning of magnetic resonance imaging (MRI) and MRS. MRI observation was focused on the size of the gland,the signal features, the location of the lesion and the extent of the tumor. MRS observation included the chemical shift of citrate(Cit), choline(Cho) and creatine(Cre) spectra, and the ratio of (Cho + Cre) /Cit SPSS 13.0 statistical analysis software was performed for statistic analysis of MRI,MRI + MRS in the diagnosis of prostate cancer to get the sensitivity,specificity and accuracy, respectively. Results Based on the analysis of MRI of prostate cancer and pathological findings, the diagnostic sensitivity,specificity and accuracy of MRI were 78.9%( 15/19),66.7%(24/36),70.9%(39/55), respectively. The diagnostic sensitivity,specificity and accuracy of MRI + MRS were 84.2%(16/19),88.9%(32/36),87.3%(48/55),respectively. There was significant difference between the two methods (P<0.05). Conclusions MRS has made it possible to obtain functional and metabolic information about prostate cancer non-invasively. Combining MRI and MRS are useful for differentiating diagnosis of benign prostate hyperplasia from prostate cancer.

Conclusion Jizhipingchuan soft capsula showed definite antitussive, an-tiasthmatic and expectorant effects.

Objective To evaluate the necessity and feasibility of low-dose dual-source CT coronary angiography imaging in the evaluation of high body mass index (BMI) patients. Methods Sixty patients with BMI≥28 kg/m2 and heart rate 65-90 beats/min were selected, and they were divided into prospective electrocardiography gated scanning group and retrospective electrocardiography gated scanning group by random digits table method with 30 cases each. The image quality, CT dose weighing index (CTDI) and dose length product (DLP) were compared between 2 groups. Results There was no statistical difference in the score of coronary image quality between retrospective electrocardiography gated scanning group and prospective electrocardiography gated scanning group:(3.47±0.61) scores vs. (3.18±0.94) scores, P>0.05. The CTDI and DLP in prospective electrocardiography gated scanning were significantly lower than those that in retrospective electrocardiography gated scanning: (32.44 ±10.18) mGy vs. (45.86 ±15.34) mGy and (458.00±95.27) mGy/cm vs. (532.15±154.43) mGy/cm, and there were statistical differences (P<0.05). Conclusion For high BMI patients, different low-dose dual-source CT scanning, especially prospective electrocardiography gated scanning, can guarantee image quality and reduce the radiation dose and the radiation damage at the same time.

Objective To discuss the prenatal ultrasound manifestations of Apert syndrome. Methods The prenatal ultrasound features of 4 fetuses identified as Apert syndrome after detailed antenatal ultrasound examinations between January, 2010 to Februry, 2014 in our hospital were analyzed. The ultrasound images and postnatal outcome or autopsy were compared to analysis the sonographic features of Apert syndrome in prenatal. Results The prenatal ultrasound characteristics and pregnant outcome of the 4 fetuses were showed as followings:(1) Skull deformity:4 fetuses were all appeared as acrocephaly, coronal suture premature close and frontal protrusion, while 3 cases (case 1-3) had“clover leaf skull deformity”features. (2) Midfacial malformation deformity:3 cases (case 1-3) were all with hypertelorism and mid-sagittal facial proifle abnormal and only 1 case (case 2) had nose hypoplasia. (3) Limbs abnormal:4 cases were all appeared as bilateral symmetry syndactyly of hands and 1 case (case 2) was diagnosed as bilateral symmetry syndactyly of feet. (4) Associated abnormality:persistent right umbilical vein in 1 case (case1), thoracic spine stenosis in 1 case (case 2), hyperechogenic renal parenchyma in 1 case (case 3) and left-diaphragmatic hernia in 1 case (case 4). (5) The pregnant outcome:3 cases underwent pregnancy termination and 1 case was labored at term. The 3 cases (case1-3) were diagnosed as bilateral symmetry syndactyly of feet after induced labor. The cleft palate and bilateral symmetry syndactyly of feet were misdiagnosed in the full-time infant (case 3), who was died two days after birth. Conclusions The Apert syndrome is a rare syndrome. It generally has typical characteristic of prenatal ultrasound, such as coronal suture premature close, acrocephaly, mid-sagittal facial profile abnormal and bilateral symmetry syndactyly of hands and feet. Prenatal diagnosis of Apert syndrome can play an important role in genetic counseling and postnatal treatment.
