Objective To evaluate the individuality of patients with primary angle-closure glaucoma and discuss the relation between individuality and glaucoma. Design Questionnaire. Participants 99 patients with primary angle-closure glaucoma and 99 healthy people. Methods Questionnaire were performed with Self-rations Anxiety seal: TH means "Time and Hurry", CH means"Competition and Hostility" and L means "Lit". The questionnaires were compartmentalizied with the scoring of TH+CH and statistical analysis; Score 50-28 means Type A behavior, 27 means Type X behavior, 26-1 means Type B behavior. Main Outcome Measures CH, TH, CH+TH. Results The quantity of primary angle-closure glaucoma in type A behavior group was 49 (64.5%), while the quantity of healthy people was 32 (36.8%). There was obvious difference between two groups (P=0.001). The scoring of TH, CH and TH+CH of primary angle-closure glaucoma patients were higher obviously than those of the healthy one (P

0.05).There was a positive correlation between the tempo of the engraftment and the progressive increase of the doses of MNC in the range of (3～5.99)?108/kg,but which was not found in the range of 6?108/kg.Conclusion These results indicate that MNC taken as an index for the measurement of the hematopoietic stem cell/progenitor content can reliably predict hematopoietic reconstitution after both HLA-matched and-mismatched sibling donor peripheral blood stem cell transplantation,with the rate and tempo of engraftment comparable with that in CD34+ cell group,and however,the target dose was reached with one apheresis in all 83 donors in MNC group(100%),as compared with 14 donors in CD34+ cell group(37.84%),suggesting that MNC may replace CD34+ cell as an independent index for the assessment of the stem cell/progenitor content in clinical practice.

Objective To evaluate the role of fetal brainstem-vermis (BV) and brainstem-tentorium (BT) angles in differential diagnosis of fetal cereballar vermis anomalies by three-dimensional ultrasonography. Methods A total of 335 normally developed fetuses at 18-34 gestational weeks were examined prospectively in Prenatal Ultrasound Center of Suzhou Municipal Hospital from July 2013 to July 2014 by three-dimensional ultrasonography scanning. The BV angles and BT angles were measured at the mid-sagittal sections of fetal heads which were obtained by three-dimensional ultrasonography. Sixteen fetuses with abnormal cerebellar vermis were selected. The BV angles and BT angles were measured and compared with the measurements of normal group. Results In normal fetuses, the mean of BV angles was (3.3±1.7)° , ranging from1.0 to 10.0°;the mean BT angle was (31.5±6.9)° , and ranging from 16.6 to 57.8° . In 16 cases of abnormal cerebellar vermis, 4 cases of Dandy-Walker Malformation (DWM) showed significantly upward rotated cerebellar vermises, the BV angles increased significantly (88.9±18.1)° , the cerebellar tentoriums were superior displaced, the BT angles increased remarkably (89.0±12.8) ° ;6 cases of Dandy-Walker variant (DWV) showed upward rotated cerebellar vermises, with increased BV angles (23.7±5.2) ° , and slightly increased BT angles (54.5±12.0)°;6 cases of Blake′s pouch cyst (BPC) showed upward rotated cerebellar vermises were, mildly increased BV angles (16.7±1.8)° , and slightly increased BT angles (50.3±8.2)° . The comparison results showed:BV angles increased with increasing severity of the condition in BPC, DWV and DWM;BT angles increased significantly in DWM. Conclusions The measurements of BV angles and BT angles are valuable in the differential diagnosis of fetal cereballar vermis anomalies. From 19 gestational weeks, a BV angle>60° is strongly suggestive of a Dandy-Walker malformation, while a measurement>10.0° and<20° favors the diagnosis of Blake′s pouch cyst.

Objective To study the value of time intensity curve of contrast enhanced ultrasound in the discrimination of benign and malignant soft tissue tumors. Methods Thirty-seven cases of soft tissue tumors were carried out contrast-enhanced ultrasound examination. The region of interest in the dynamic images were chosen to carry out Gamma-Variate curve fitting through Q-LAB software and made a quantitative analysis. Then they were compared with pathological diagnosis to analyze the ultrasound imaging performance of benign and malignant tumors and their characteristics of micro-irrigation. Results Thirty-seven cases of soft tissue tumors were pathologically diagnosed 21 cases of benign and malignant in 16 cases. The perfusion of benign tumors were mainly uniformity (19/21) or potentialization (2/21). The perfusion of malignant tumors were mainly uniformity (10/16) or nonuniformity (6/16). There were no significant differences in time to peak(TTP) and arrival time of contrast agent(AT) between benign and malignant tumors( P ＞0.05). The upslope rate(A) and the derived peak intensity(DPI) in benign group were significantly less than malignant group ( P ＜0.05). Conclusions Time-intensity curve analysis of contrast-enhanced ultrasound showed that benign and malignant soft tissue tumors were different in perfusion,and it will be of a certain value for the clinical differential diagnosis.

Objective To prospectively evaluate the value of diffusion-weighted imaging with background signal suppression (DWIBS) in the detection and diagnoses of metastatic cervical lymph nodes. Methods Twenty patients with head and neck squamous cell carcinomas underwent conventional MRI and DWIBS. The ADC values were measured and compared between metastatic and benign lymph nodes. The abilities of DWIBS and conventional MRI in the evaluation of metastatic cervical lymph nodes were compared. Results Conventional MRI demonstrated 101 lymph nodes, in which 58 were diagnosed as metastatic nodes. When MRI criteria were used for discrimination between metastatic and benign nodes, the obtained sensitivity, specificity, accuracy, positive and negative predictive value were 78% (47/60), 81%(44/54), 80% (91/114), 82% (47/57) and 77% (44/57), respectively. The mean ADC values of metastatic nodes (n =60) and benign nodes (n =54) were (0.945 ±0.122) × 10-3 mm2/s and (1. 210 ±0. 151 ) × 10-3 mm2/s ( t = - 10. 354 ,P ＜0. 01 ). When an ADC value of 1. 090 × 10 -3 mm2/s was used as the threshold for discrimination between metastatic and benign nodes, the obtained sensitivity, specificity,accuracy, positive and negative predictive value were 88% (53/60), 80% (43/54), 84% (96/114), 83%(53/64) and 86% (43/50), respectively. Conclusion DWIBS is helpful in diagnosing metastatic cervical lymph nodes of head and neck squamous cell carcinoma, and is superior to conventional MRI in their detection.

Objective To investigate the clinical characteristics of diffuse alveolar hemorrhage. Methods 12 patients with diffuse alveolar hemorrhage hospitalized in Guangzhou NO.1 Hospital were included in the research, whose clinical characteristics were analyzed. Results 7 cases of the 12 diffuse alveolar hemorrhage cases were male and 5 cases were female. 8 cases were caused by ANCA associated vasculitis , 1 cases by connective tissue disease, 1 cases by poisoning, and 2 cases of unknown etiology (medication could be considered). The clinical manifestations were fever (91.67%), hemoptysis (100%), anemia (100%), and dyspnea (3.33%). Conclusion Diffuse alveolar hemorrhage is a life-threatening clinical syndrome. It can be caused by many causes. It should be considered if there is the presence of hemoptysis, dyspnea, anemia, etc. Timely examination and early intervention can effectively improve the prognosis of the disease.

Objective To compare the clinical effect between CO2-1aser assisted and cold instrument assisted suspension laryngoscopic surgery for vocal fold cyst.Methods From January, 2011 to December, 2014, 72 patients with vocal fold cyst, which diagnosed by strobolaryngoscopy, were randomly divided into CO2-1aser assisted group and cold instrument group.Strobolaryngoscopy, acoustic analysis and perceptual voice analyses were performed on each patient before surgery, 1 month, and 3 months after surgery, respectively.Results All operations were successfully completed.The complete vocal fold cyst resection rate of CO2-1aser assisted group was significantly higher than cold instrument group (29/36, 80.5％ vs 21/36, 58.3％, P ＜ 0.05), especially the left vocal fold cyst (13/16, 81.3％ vs 9/19, 47.4％, P ＜ 0.05).The complete right vocal fold epidermoid cyst resection rate was significantly higher than retention cyst (17/19, 89.4％ vs 11/18, 61.1％, P ＜ 0.05).Two recurrent cases were found in cold instrument group but no recurrent cases in CO2-laser assisted group (0/36, 0％ vs 2/36, 5.6％, P ＞ 0.05).Correlation analysis showed that vocal fold cyst recurrence was related to complete resection rate and has no relation with surgical methods, histopathological types and position.Subjective and objective assessment of voice quality in preoperative, 1-month postoperative and 3-month postoperative were similer between CO2-1aser assisted group and cold instrument group (P ＞ 0.05).Conclusion The CO2-laser assisted suspension laryngoscopic surgery for vocal fold cyst, can increase the surgical precision, reduce the left hand impact, improve the complete resection rate and reduce the recurrence rate.
