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

Objective To investigate the effect of mixed-skin grafting with autologous microskin and allogenetic acellular dermal matrix microskin on wound healing in rats,and to make a further study on the related mechanism.Methods Wistar rats were served as a allogenetic acellular dermal matrix donor rats,and SD rats as acceptors with mould of full thickness skin defects on their back.The ninety SD rats were divided into 5 groups with 18 rats in each group.Group 1 was transplanted with autologous microskin,and group 2 with allogenetic acellular dermal matrix microskin.Groups 3,4 and 5 were grafted with mixed-skin ratio between autologous microskin and allogenetic acellular dermal matrix microskin 1 ∶ 1,1 ∶ 0.5 and 1 ∶ 0.25,repectively.The rate of wound healing was measured,wound samples collected,hematoxylin and eosin stain carried out,fibronectin (FN) and laminin (LN)detected,and intergroup comparison made,respectively,2,3 and 4 weeks after skin grafting.Results The wound healing rates and FN and LN expression of mixed-skin grafting groups were higher than those of the group with autologous microskin grafting.The group of 1 ∶ 0.25 obviously increased (P＜0.05 or P＜0.01).Conclusions The wound healing rate with mixed-skin grafting is higher than that with autologous microskin grafting.The best effect is achieved when the skin ratio between autologous microskin and allogenetic acellular dermal matrix microskin is 1 ∶ 0.25.It is possibly due to the increase of FN and LN on wound skin surface.

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 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 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.

Objective To explore the effect and application value of percutaneous transhepatic various interventional technique for treatment of common bile duct stones.Methods 46 patients with common bile duct stones were treated.All patients were treated by percutaneous transhepatic cholangiopancreatography in order to confirm the number and location and size of the stones.Place me-chanical lithotripsy net according to the size of stones.Then percutaneous transhepatic balloon dilation.Postoperatively biliary tract was drained for 2 weeks.Results 45 operations were successful,The successful rate was 97.83%.Complete stone removal was obtained with one session in 41 patients and two sessions in 4 cases,respectively.There was no serious complications occurred during the operation. There was no perforation and bleeding,but hyperamylasemia occurred in 3 patients and acute pancreatitis occurred in 1 patient and bile perito-nitis occurred in 2 patients.Conclusion Percutaneous transhepatic various interventional technique can keep the function of papillary sphincter and is a valuable methed for patients suffering from common bile duct stones with a high successful rate and safety.
