Background There is multi-dimensional order of spatial stereopsis perception in human,however,current stereopsis examination is zero-order of position disparity.A multi-dimensional space perception model is very important for the detection of stereoacuity.Objective This study was to screen the deficit of zero-order,first-order,second-order multi-dimensional spatial stereopsis perception in amblyopia and strabismus children and to explore the association of zero-order,first-order,second-order spatial perception deficit.Methods Multidimensional spacial perception was examined in 79 children aged 4-14 years in Beijing Children' s Hospital.Nineteen normal children,19 children with ametropia amblyopia,12 children with anisometropic amblyopia,18 children with strabismus and 11 children with strabismus combined amblyopia were included this study.The random-dot and line spatial stereopsis perception in zero-order,first-order and second-order were examined with a new system of multidimensional space perception screening.Written informed consent was obtained from each subject or custodian before any ocular examination associated with this study.Results Absence of zero-order,first-order,second-order random-dot channel was found in 24 children (24/79,30.4％),18 children (18/79,22.8％) and 24 children (24/79,30.4％) respectively,with an average percentage of 27.9％.Absence of zero-order,first-order,second-order line channel was examined in 37 children (37/79,46.8％),37 children (37/79,46.8％),32 children (32/79,40.5％),with an average percentage of 44.7％.In the children with a deficiency of the zero-order spatial perception,the children who still remained the first-order or/and second-order spatial perception of random-dot accounted for 41.6％ and that of lines accounted for 43.2％.In children without deficiency of zero-order random-dot or lines spatial space perception,deficiency of first-order and/or second-order spatial perception was in 37.5％ children.Various order spatial perception deficiency was seen in children suffering from amblyopia or strabismus compared with normal group(P ＜ 0.05).Conclusions There exists spatial perception deficiency in children with amblyopia or strabismus.The patients with zero-order spatial perception absence partially remain a first-order or/and second-order spatial perception;while the patients with normal zero-order spatial perception might have first-order or second-order spatial perception deficiency.The multi-dimensional space perception model has a directive role for the training of visual information process and the treatment of spatial perceptual learning in children with amblyopia or strabismus.

BACKGROUNDSinonasal malignancy with orbital invasion is rare. The objective of the current study was to evaluate the clinical and pathological features, treatment outcomes and survival rates for these malignancies.

METHODSNinety-three patients who were treated between 1997 and 2007 were retrospectively reviewed. Age, life style, symptoms, location of lesions, previous occurrences, histological subtypes, and treatment modalities were analyzed.

RESULTSNinety-three patients were evaluated, including 51 men and 42 women: the gender ratio was 1.2 men to 1.0 women. The median age was 40.5 years old. The nasal cavity (34.4%), the maxillary sinus (29.0%) and the ethmoid sinus (19.4%) were the most common primary malignant tumor sites. Almost half of the patients, 44.1% had squamous cell carcinoma, 13.9% had neuroectodermal carcinoma, 11.7% had rhabdomyosarcoma, 9% had adenocarcinoma and salivary gland-type carcinoma, and 11% had other malignancy. The majority of patients presented with T3/T4 (99%), N0 (93.1%), M0 (98%) disease. The distant metastasis rate was 20.9%. The overall survival and disease-free survival rates were 68.1% and 40.9% at three years, respectively. When the overall survival rate was computed according to the epicenter of the original malignant tumor, patients with nasal cavity malignancy and maxillary sinus had the best survival, and patients with ethmoid sinus malignancy had the worse survival (P = 0.03). According to their pathology classification, patients with rhabdomyosarcoma had worse overall survival than those with squamous cell carcinoma, or neuroendocrine carcinoma (P < 0.001). Squamous cell carcinoma and rhabdomyosarcoma invaded the orbit more often and malignancy of the nasal cavity invaded the orbit more than malignancy of the nasal sinus.

CONCLUSIONSFor nasal orbital tumors early diagnosis is crucial. Orbital exenteration and postoperative rehabilitation should be carefully considered. The current data suggest that surgical resection with postoperative radiation therapy may offer durable local control.

OBJECTIVETo investigate the objective index of the diagnosis of varicocele (VC) in infertile males by ultrasonography and the testis volume changes resulting from varicocele.

METHODSForty-six healthy male volunteers and 178 infertile men with left varicocele were detected by high frequency ultrasound. According to the clinical data and ultrasonographic results, the 178 VC patients were divided into 4 groups, SVC group (45 cases), VC I group (44 cases), VC II group (48 cases), and VC III group (41 cases).

RESULTS(1) The differences in DR, DV, Vmax, TR and testis volume between the right and the left sides were not statistically significant in the control group (P > 0.05). (2) The differences in DR, DV, Vmax and TR between the experimental and control groups as well as among the VC groups were statistically significant (P < 0.001). (3) The left testis volume was smaller than the right among the VC groups (P < 0.01). The right testis volume of the VC II and VC III groups was significantly smaller than that of the control group ( P < 0.05), and the left testis volume in the VC III group was significantly smaller than that of the SVC group (P < 0.05).

CONCLUSION(1) High frequency ultrasound can detect the accurate diameter of the internal spermatic vein, hemodynamic index and testis volume of infertile men with VC, and hence help to screen the causes of male infertility. (2) Unilateral varicocele can cause a volume decrease in both testes, especially in the left. Both unilateral SVC and VC can cause testicular atrophy, and the more serious VC, the higher testicular atrophy.

OBJECTIVETo clone and identify one novel regeneration related gene H(3) (CA854305) from the differential expression genes library we had set up before.

METHODSUse the method of Northern blot to detect the different expressions of the novel gene under different situations, employ the technique of in silico cloning to scan the span of the novel gene, and analyze their sequences. Also we used reverse transcription PCR to validate the largest open reading frame.

RESULTSNorthern blotting results of H(3) (CA854305) showed that the transplanted group had more efficient and extensive expression than untreated and uninjured groups 5 days after spinal cord injury, while the untreated group had more extensive expression than uninjured group. It implied that H(3) might have some relationship with nerve regeneration after spinal cord injury. From the results of in silico cloning we got a longest contig of 1635 bp and an largest open reading frame of 542 bp from 49 to 591 bp correspondent with the Cozak rules. Reverse transcription PCR validated the largest open reading frame sequence primarily.

CONCLUSIONSWe got the sequence of novel gene H(3) which might be one of the regenerationjrelated genes. Key words:Gene library; Genes; Nerve regeneration; Spinal cord injuries.

OBJECTIVETo explore the sonographic characteristics of intraveous leiomyomatosis (IVL) with intracardiac extension and improve its diagnosis.

METHODSThe clinical and sonographic data of 13 female patients with pathologically confirmed IVL with intracardiac extension who were treated in our hospital between 2002 and 2012 were retrospectively analyzed. These patients aged 44 years old (range: 38-49 years), and 10 of them were first-episode patients and the remaining 3 were recurrent patients. Eight patients had a history of hysterectomy for leiomyoma.

RESULTSThe first-episode symptoms included exertional chest tightness and shortness of breath (n=5), abdominal distention and edema of low extermity (n=4), exertional palpitation of cardiac origin (n=3), and menorrhagia (n=1). Ultrasonography showed that all patients had isoechoic or hypoechoic tumors extended through the inferior vena cava into right heart chambers (62% in right atrium alone and 38% in right ventricle and atrium). Nine masses in right heart chamber (69.2%) were oval and 4 (30.8%) were serpentine, which were all with well-demarcated borders and most (80%) with heteroechogenic texture. Ten patients had hypoechoic or mixed echoic tumors in pelvic cavity or uterus, and 6 of them had abundant blood flow.

CONCLUSIONSIVL with intracardiac extension has certain sonographic characteristics. Ultrasonography is a valuable tool in the diagnosis of IVL with intracardiac extension.

OBJECTIVETo evaluate the clinical value of (89)SrCl(2) (Ke xing Inc, Shanghai) as a palliative therapy modality for cancer patients with bone metastasis.

METHODSIn 504 cancer patients with painful limitation of movement due to bony metastasis, a dose of 1.48-2.22 MBq/kg (40-60 uCi/kg) iv infusion of (89)SrCl(2) was given.

RESULTSIn 97 patients (19.2%) there was no improvement in pain and life quality, 298 patients (59.1%) showed mild to moderate improvement (moderately effective), 109 patients (21.6%) became free of pain and were subsequently fully ambulatory (markedly effective). The pain relief appeared from D1-D46 after (89)SrCl(2) administration, most frequently from D5-D14. The palliative effect could last for about 56 days to 13 months. Repeated bone scans of some patients showed that the metastatic foci in the bone became smaller or even disappeared gradually after the administration of (89)SrCl(2). Approximately 55% of patients experienced grade I approximately III bone marrow depression attributable to (89)SrCl(2), which would return to the pre-treatment level within 3 approximately 9 months.

CONCLUSION(89)SrCl(2) is effective and safe for the relief of bone pain and improvement of quality of life in cancer patients with painful bony metastasis.

Objective:To explore the influence of region of interest(ROI)size on signal-to-noise ratio(SNR)measurement during the test of magnetic resonance(MR)quality control(QC),so as to provide references for selecting ROI in conducting SNR measurement during MR QC test.Methods:According to the national health industry standard"Specification of image quality test and evaluation for medical magnetic resonance imaging(MRI)equipment"(WS/T 263-2006),this study utilized Magphan SMR170 performance test phantom(abbreviation:SMR170 phantom)to perform QC test on MR equipment after conducted three times tests.The slices of SNR measurement were selected on the obtained QC images,and 41 circular ROIs,which were incremental from 200mm2 to 4200mm2 as 100mm2,were sequentially chosen in the central region of the images on the SNR slices.The SNR was calculated according to formula,and then,the SNR curve that changed with the increasing of ROI size was formed.Finally,the influence of ROI size on SNR was obtained.Results:In conducting the QC test for MRI equipment by SMR170 phantom,the influence of the selected ROI size of central region of image on SNR was significant.The SNR fluctuation could not be really reflected when ROI>1000mm2 because the basically stable SNR leaded to the SNR change could not be timely found.When ROI<1000mm2,the signal means slowly increased with the increasing of ROI size,and the increase amplitude of noise was larger,and the SNR faster decreased and was smaller and smaller with ROI increase,and it tended towards stability at finally.Conclusion:When SMR170 phantom is used to conduct QC test for MR equipment and SNR is measured,it is recommended to select≤1000 mm2 of ROI size of the central region of the images,and to choose the same ROI for each measurement,which can really reflect the SNR change and ensure the result of each measurement has comparability.
